This is borderline programming, but look into using tr:

$ echo "this is just a test" | tr -s ' ' | tr ' ' '_'

Should do it. The first invocation squeezes the spaces down, the second replaces with underscore. You probably need to add TABs and other whitespace characters, this is for spaces only.

Use sort.

• float stores floating-point values, that is, values that have potential decimal places
• int only stores integral values, that is, whole numbers

So while both are 32 bits wide, their use (and representation) is quite different. You cannot store 3.141 in an integer, but you can in a float.

Dissecting them both a little further:

In an integer, all bits are used to store the number value. This is (in Java and many computers too) done in the so-called two's complement. This basically means that you can represent the values of −2³¹ to 2³¹ − 1.

In a float, those 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa. They are laid out as follows:

S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM

There is a single bit that determines whether the number is negative or non-negative (zero is neither positive nor negative, but has the sign bit set to zero). Then there are eight bits of an exponent and 23 bits of mantissa. To get a useful number from that, (roughly) the following calculation is performed:

M × 2^E

(There is more to it, but this should suffice for the purpose of this discussion)

The mantissa is in essence not much more than a 24-bit integer number. This gets multiplied by 2 to the power of the exponent part, which, roughly, is a number between −128 and 127.

Therefore you can accurately represent all numbers that would fit in a 24-bit integer but the numeric range is also much greater as larger exponents allow for larger values. For example, the maximum value for a float is around 3.4 × 10³⁸ whereas int only allows values up to 2.1 × 10⁹.

But that also means, since 32 bits only have 4.2 × 10⁹ different states (which are all used to represent the values int can store), that at the larger end of float's numeric range the numbers are spaced wider apart (since there cannot be more unique float numbers than there are unique int numbers). You cannot represent some numbers exactly, then. For example, the number 2 × 10¹² has a representation in float of 1,999,999,991,808. That might be close to 2,000,000,000,000 but it's not exact. Likewise, adding 1 to that number does not change it because 1 is too small to make a difference in the larger scales float is using there.

Similarly, you can also represent very small numbers (between 0 and 1) in a float but regardless of whether the numbers are very large or very small, float only has a precision of around 6 or 7 decimal digits. If you have large numbers those digits are at the start of the number (e.g. 4.51534 × 10³⁵, which is nothing more than 451534 follows by 30 zeroes – and float cannot tell anything useful about whether those 30 digits are actually zeroes or something else), for very small numbers (e.g. 3.14159 × 10⁻²⁷) they are at the far end of the number, way beyond the starting digits of 0.0000...

Another solution would be,you can get the object itself as value if you are not mentioning it's id as value: Note: [value] and [ngValue] both works here.

<select (change)="your_method(values[$event.target.selectedIndex])">
  <option *ngFor="let v of values" [value]="v" >  
    {{v.name}}
  </option>
</select>

In ts:

your_method(v:any){
  //access values here as needed. 
  // v.id or v.name
}

Note: If you are using reactive form and you want to catch selected value on form Submit, you should use [ngValue] directive instead of [value] in above scanerio

Example:

  <select (change)="your_method(values[$event.target.selectedIndex])" formControlName="form_control_name">
      <option *ngFor="let v of values" [ngValue]="v" >  
        {{v.name}}
      </option>
    </select>

In ts:

form_submit_method(){
        let v : any = this.form_group_name.value.form_control_name;  
    }

Another way:

x=$'Some\nstring'
readarray -t y <<<"$x"

Or, if you don't have bash 4, the bash 3.2 equivalent:

IFS=$'\n' read -rd '' -a y <<<"$x"

You can also do it the way you were initially trying to use:

y=(${x//$'\n'/ })

This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'. To make it work, you need to restrict the word separator before parsing it:

IFS=$'\n' y=(${x//$'\n'/ })

...and then, since you are changing the separator, you don't need to convert the \n to space anymore, so you can simplify it to:

IFS=$'\n' y=($x)

This approach will function unless $x contains a matching globbing pattern (such as "*") - in which case it will be replaced by the matched file name(s). The read/readarray methods require newer bash versions, but work in all cases.

Try following example it works !!!

Use [Handler] in onCreate() method which makes use of postDelayed() method that Causes the Runnable to be added to the message queue, to be run after the specified amount of time elapses that is 0 in given example. 1

Refer this code :

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
    //------------------
    //------------------
    android.os.Handler customHandler = new android.os.Handler();
            customHandler.postDelayed(updateTimerThread, 0);
}

private Runnable updateTimerThread = new Runnable()
{
        public void run()
        {
            //write here whaterver you want to repeat
            customHandler.postDelayed(this, 1000);
        }
};

Create dictionaries for both arrays using _.keyBy(), merge the dictionaries, and convert the result to an array with _.values(). In this way, the order of the arrays doesn't matter. In addition, it can also handle arrays of different length.

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = _(arr1) // start sequence_x000D_
  .keyBy('member') // create a dictionary of the 1st array_x000D_
  .merge(_.keyBy(arr2, 'member')) // create a dictionary of the 2nd array, and merge it to the 1st_x000D_
  .values() // turn the combined dictionary to array_x000D_
  .value(); // get the value (array) out of the sequence_x000D_
_x000D_
console.log(merged);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.14.0/lodash.min.js"></script>

Using ES6 Map

Concat the arrays, and reduce the combined array to a Map. Use Object#assign to combine objects with the same member to a new object, and store in map. Convert the map to an array with Map#values and spread:

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = [...arr1.concat(arr2).reduce((m, o) => _x000D_
  m.set(o.member, Object.assign(m.get(o.member) || {}, o))_x000D_
, new Map()).values()];_x000D_
_x000D_
console.log(merged);

You can also use it in named_scope if You want to put there others conditions

for example include some other model:

named_scope 'get_by_ids', lambda { |ids| { :include => [:comments], :conditions => ["comments.id IN (?)", ids] } }

Put each line in cmd or all of theme in the batch file:

@echo off

if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)

"Put your command here"

it works fine for me.

I suggest that all events for Spinner are divided on two types:

1. User events (you meant as "click" event).

2. Program events.

I also suggest that when you want to catch user event you just want to get rid off "program events". So it's pretty simple:

private void setSelectionWithoutDispatch(Spinner spinner, int position) {
    AdapterView.OnItemSelectedListener onItemSelectedListener = spinner.getOnItemSelectedListener();
    spinner.setOnItemSelectedListener(null);
    spinner.setSelection(position, false);
    spinner.setOnItemSelectedListener(onItemSelectedListener);
}

There's a key moment: you need setSelection(position, false). "false" in animation parameter will fire event immediately. The default behaviour is to push event to event queue.

This exception happened when I forgot to close the connections

Responding because this answer came up first for search when I was having the same issue:

[08S01][unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist

MSSQL named instances have to be configured properly without setting the port. (documentation on the freetds config says set instance or port NOT BOTH)

freetds.conf

[Name]
host = Server.com
instance = instance_name
#port = port is found automatically, don't define explicitly
tds version = 8.0
client charset = UTF-8

And in odbc.ini just because you can set Port, DON'T when you are using a named instance.

A valid domain is for me something I'm able to register or at least something that looks like I could register it. This is the reason why I like to separate this from "localhost"-names.

And finally I was interested in the main question if avoiding Regex would be faster and this is my result:

<?php
function filter_hostname($name, $domain_only=false) {
    // entire hostname has a maximum of 253 ASCII characters
    if (!($len = strlen($name)) || $len > 253
    // .example.org and localhost- are not allowed
    || $name[0] == '.' || $name[0] == '-' || $name[ $len - 1 ] == '.' || $name[ $len - 1 ] == '-'
    // a.de is the shortest possible domain name and needs one dot
    || ($domain_only && ($len < 4 || strpos($name, '.') === false))
    // several combinations are not allowed
    || strpos($name, '..') !== false
    || strpos($name, '.-') !== false
    || strpos($name, '-.') !== false
    // only letters, numbers, dot and hypen are allowed
/*
    // a little bit slower
    || !ctype_alnum(str_replace(array('-', '.'), '', $name))
*/
    || preg_match('/[^a-z\d.-]/i', $name)
    ) {
        return false;
    }
    // each label may contain up to 63 characters
    $offset = 0;
    while (($pos = strpos($name, '.', $offset)) !== false) {
        if ($pos - $offset > 63) {
            return false;
        }
        $offset = $pos + 1;
    }
    return $name;
}
?>

Benchmark results compared with velcrow 's function and 10000 iterations (complete results contains many code variants. It was interesting to find the fastest.):

filter_hostname($domain);// $domains: 0.43556308746338 $real_world: 0.33749794960022
is_valid_domain_name($domain);// $domains: 0.81832790374756 $real_world: 0.32248711585999

$real_world did not contain extreme long domain names to produce better results. And now I can answer your question: With the usage of ctype_alnum() it would be possible to realize it without regex, but as preg_match() was faster I would prefer that.

If you don't like the fact that "local.host" is a valid domain name use this function instead that valids against a public tld list. Maybe someone finds the time to combine both.

Apparently GitHub now offer git training courses to companies. Quoth their blog post about it:

I’ve been down to the Google campus a number of times in the last few weeks helping to train the Androids there in Git. I was asked by Shawn Pearce (you may know him from his Git and EGit/JGit glory – he is the hero that takes over maintanance when Junio is out of town) to come in to help him train the Google engineers working on Andriod in transitioning from Perforce to Git, so Android could be shared with the masses. I can tell you I was more than happy to do it.

[…]

Logical Awesome is now officially offering this type of custom training service to all companies, where we can help your organization with training and planning if you are thinking about switching to Git as well.

Emphasis mine.

Static method example

class StaticDemo
{

 public static void copyArg(String str1, String str2)
    {
       str2 = str1;
       System.out.println("First String arg is: "+str1);
       System.out.println("Second String arg is: "+str2);
    }
    public static void main(String agrs[])
    {
      //StaticDemo.copyArg("XYZ", "ABC");
      copyArg("XYZ", "ABC");
    }
}

Output:

First String arg is: XYZ

Second String arg is: XYZ

As you can see in the above example that for calling static method, I didn’t even use an object. It can be directly called in a program or by using class name.

Non-static method example

class Test
{
    public void display()
    {
       System.out.println("I'm non-static method");
    }
    public static void main(String agrs[])
    {
       Test obj=new Test();
       obj.display();
    }
}

Output:

I'm non-static method

A non-static method is always be called by using the object of class as shown in the above example.

Key Points:

How to call static methods: direct or using class name:

StaticDemo.copyArg(s1, s2);

or

copyArg(s1, s2);

How to call a non-static method: using object of the class:

Test obj = new Test();

check before use

You can use computedStyleMap()

The answer is valid but sometimes you need to check what unit it returns, you can get that without any slice() or substring() string.

var element = document.querySelector('.js-header-rep');
element.computedStyleMap().get('padding-left');

var element = document.querySelector('.jsCSS');_x000D_
var con = element.computedStyleMap().get('padding-left');_x000D_
console.log(con);

.jsCSS {_x000D_
  width: 10rem;_x000D_
  height: 10rem;_x000D_
  background-color: skyblue;_x000D_
  padding-left: 10px;_x000D_
}

<div class="jsCSS"></div>

Wrap the menu contents with another div:

<div id="floatingMenu">
    <div>
        <a href="http://www.google.com">Test 1</a>
        <a href="http://www.google.com">Test 2</a>
        <a href="http://www.google.com">Test 3</a>
    </div>
</div>

And the CSS:

#floatingMenu {
    clear: both;
    position: fixed;
    width: 100%;
    height: 30px;
    background-color: #78AB46;
    top: 5px;
}

#floatingMenu > div {
    margin: auto;
    text-align: center;
}

And about your page below the menu, you can give it a padding-top as well:

#content {
    padding-top: 35px; /* top 5px plus height 30px */
}

sed would be a better choice (stream editor)

tail -n0 -f <file> | sed -n '/search string/p'

and then if you wanted the tail command to exit once you found a particular string:

tail --pid=$(($BASHPID+1)) -n0 -f <file> | sed -n '/search string/{p; q}'

Obviously a bashism: $BASHPID will be the process id of the tail command. The sed command is next after tail in the pipe, so the sed process id will be $BASHPID+1.

  /sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'

setTimeout(() => { // your code here }, 0);

I wrapped my code in setTimeout and it worked

arrow offers many useful functions for dates and times. This bit of code provides an answer to the question and shows that arrow is also capable of formatting dates easily and displaying information for other locales.

>>> import arrow
>>> dateStrings = [ 'Jun 1  2005 1:33PM', 'Aug 28 1999 12:00AM' ]
>>> for dateString in dateStrings:
...     dateString
...     arrow.get(dateString.replace('  ',' '), 'MMM D YYYY H:mmA').datetime
...     arrow.get(dateString.replace('  ',' '), 'MMM D YYYY H:mmA').format('ddd, Do MMM YYYY HH:mm')
...     arrow.get(dateString.replace('  ',' '), 'MMM D YYYY H:mmA').humanize(locale='de')
...
'Jun 1  2005 1:33PM'
datetime.datetime(2005, 6, 1, 13, 33, tzinfo=tzutc())
'Wed, 1st Jun 2005 13:33'
'vor 11 Jahren'
'Aug 28 1999 12:00AM'
datetime.datetime(1999, 8, 28, 0, 0, tzinfo=tzutc())
'Sat, 28th Aug 1999 00:00'
'vor 17 Jahren'

See http://arrow.readthedocs.io/en/latest/ for more.

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

grep -q is useful for this purpose.

The same using awk:

string="unix-bash 2389"
character="@"
printf '%s' "$string" | awk -vc="$character" '{ if (gsub(c, "")) { print "Found" } else { print "Not Found" } }'

Output:

Not Found

string="unix-bash 2389"
character="-"
printf '%s' "$string" | awk -vc="$character" '{ if (gsub(c, "")) { print "Found" } else { print "Not Found" } }'

Output:

Found

This error message is displayed when you have an error in your query which caused it to fail. It will manifest itself when using:

• mysql_fetch_array/mysqli_fetch_array()
• mysql_fetch_assoc()/mysqli_fetch_assoc()
• mysql_num_rows()/mysqli_num_rows()

Note: This error does not appear if no rows are affected by your query. Only a query with an invalid syntax will generate this error.

Troubleshooting Steps

• Make sure you have your development server configured to display all errors. You can do this by placing this at the top of your files or in your config file: error_reporting(-1);. If you have any syntax errors this will point them out to you.

• Use mysql_error(). mysql_error() will report any errors MySQL encountered while performing your query.

  Sample usage:

  mysql_connect($host, $username, $password) or die("cannot connect"); 
  mysql_select_db($db_name) or die("cannot select DB");
  
  $sql = "SELECT * FROM table_name";
  $result = mysql_query($sql);
  
  if (false === $result) {
      echo mysql_error();
  }
  

• Run your query from the MySQL command line or a tool like phpMyAdmin. If you have a syntax error in your query this will tell you what it is.

• Make sure your quotes are correct. A missing quote around the query or a value can cause a query to fail.

• Make sure you are escaping your values. Quotes in your query can cause a query to fail (and also leave you open to SQL injections). Use mysql_real_escape_string() to escape your input.

• Make sure you are not mixing mysqli_* and mysql_* functions. They are not the same thing and cannot be used together. (If you're going to choose one or the other stick with mysqli_*. See below for why.)

Other tips

mysql_* functions should not be used for new code. They are no longer maintained and the community has begun the deprecation process. Instead you should learn about prepared statements and use either PDO or MySQLi. If you can't decide, this article will help to choose. If you care to learn, here is good PDO tutorial.

I was trying to save a JSON object from a XHR request into a HTML5 data-* attribute. I tried many of above solutions with no success.

What I finally end up doing was replacing the single quote ' with it code ' using a regex after the stringify() method call the following way:

var productToString = JSON.stringify(productObject);
var quoteReplaced = productToString.replace(/'/g, "'");
var anchor = '<a data-product=\'' + quoteReplaced + '\' href=\'#\'>' + productObject.name + '</a>';
// Here you can use the "anchor" variable to update your DOM element.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

gc() can help

saving data as .RData, closing, re-opening R, and loading the RData can help.

you can check the IMEI #, http://developer.android.com/reference/android/telephony/TelephonyManager.html#getDeviceId%28%29

if i recall on the emulator this return 0. however, there's no documentation i can find that guarantees that. although the emulator might not always return 0, it seems pretty safe that a registered phone would not return 0. what would happen on a non-phone android device, or one without a SIM card installed or one that isn't currently registered on the network?

seems like that'd be a bad idea, to depend on that.

it also means you'd need to ask for permission to read the phone state, which is bad if you don't already require it for something else.

if not that, then there's always flipping some bit somewhere before you finally generate your signed app.

I export lists into YAML format with CPAN YAML package.

l <- list(a="1", b=1, c=list(a="1", b=1))
yaml::write_yaml(l, "list.yaml")

Bonus of YAML that it's a human readable text format so it's easy to read/share/import/etc

$ cat list.yaml
a: '1'
b: 1.0
c:
  a: '1'

All the solutions written here don't help because when you do SaveChanges(), insert statements are sent to database one by one, that's how Entity works.

And if your trip to database and back is 50 ms for instance then time needed for insert is number of records x 50 ms.

You have to use BulkInsert, here is the link: https://efbulkinsert.codeplex.com/

I got insert time reduced from 5-6 minutes to 10-12 seconds by using it.

Login in with System Admin User Account and execute below SQL Procedure.

begin
dbms_xdb.sethttpport('Your Port Number');
end;

Then open the Browser and access the below URL

http://127.0.0.1:YourPortNumber/apex/

Here's a plain javascript (no library required) solution:

function removeUndefinedProps(obj) {
    for (var prop in obj) {
        if (obj.hasOwnProperty(prop) && obj[prop] === undefined) {
            delete obj[prop];
        }
    }
}

In any given Bash session, set the history file to /dev/null by typing:

export HISTFILE=/dev/null

Note that, as pointed out in the comments, this will not write any commands in that session to the history!

Just don't mess with your system administrator's hard work, please ;)

Doodad's solution is more elegant. Simply unset the variable: unset HISTFILE (thanks!)

I closed VS, deleted the node_modules folder.

Then ran:

npm i -D -E [email protected] css- 
[email protected] [email protected] mini-css- 
[email protected] [email protected] [email protected] 
[email protected] [email protected] 

Then had to change the property to not read only on node_modules folder once it got done running.

Then ran:

npm i @microsoft/signalr @types/node

Then opened back up the project in VS and the package.json looked right with the dependencies.

Along the same lines as others talking about read only on node_modules folder and closing down VS to run npm install over.

Another way is to use:

@model Tuple<LoginViewModel,RegisterViewModel>

I have explained how to use this method both in the view and controller for another example: Two models in one view in ASP MVC 3

In your case you could implement it using the following code:

In the view:

@using YourProjectNamespace.Models;
@model Tuple<LoginViewModel,RegisterViewModel>

@using (Html.BeginForm("Login1", "Auth", FormMethod.Post))
{
        @Html.TextBoxFor(tuple => tuple.Item2.Name, new {@Name="Name"})
        @Html.TextBoxFor(tuple => tuple.Item2.Email, new {@Name="Email"})
        @Html.PasswordFor(tuple => tuple.Item2.Password, new {@Name="Password"})
}

@using (Html.BeginForm("Login2", "Auth", FormMethod.Post))
{
        @Html.TextBoxFor(tuple => tuple.Item1.Email, new {@Name="Email"})
        @Html.PasswordFor(tuple => tuple.Item1.Password, new {@Name="Password"})
}

Note that I have manually changed the Name attributes for each property when building the form. This needs to be done, otherwise it wouldn't get properly mapped to the method's parameter of type model when values are sent to the associated method for processing. I would suggest using separate methods to process these forms separately, for this example I used Login1 and Login2 methods. Login1 method requires to have a parameter of type RegisterViewModel and Login2 requires a parameter of type LoginViewModel.

if an actionlink is required you can use:

@Html.ActionLink("Edit", "Edit", new { id=Model.Item1.Id })

in the controller's method for the view, a variable of type Tuple needs to be created and then passed to the view.

Example:

public ActionResult Details()
{
    var tuple = new Tuple<LoginViewModel, RegisterViewModel>(new LoginViewModel(),new RegisterViewModel());
    return View(tuple);
}

or you can fill the two instances of LoginViewModel and RegisterViewModel with values and then pass it to the view.

To solve the same issue as OP, I just had to find cudart64_101.dll on my disk (in my case C:\Program Files\NVIDIA Corporation\NvStreamSrv) and add it as variable environment (that is add value C:\Program Files\NVIDIA\Corporation\NvStreamSrv)cudart64_101.dll to user's environment variable Path).

Sorry not sure what was going on this worked in the end:

<VirtualHost *> 
    ServerName example.com
    DocumentRoot /var/www/html/mjp

    Alias /ncn "/var/www/html/ncn"

    <Directory "/var/www/html/ncn">
        Options None
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

use the following rule for validating radio button group selection

myRadioGroupName : {required :true}

myRadioGroupName is the value you have given to name attribute

import sys
print(sys.argv[0])

This will print foo.py for python foo.py, dir/foo.py for python dir/foo.py, etc. It's the first argument to python. (Note that after py2exe it would be foo.exe.)

Issue related to git commands on Windows operating system:

$ git add --all

warning: LF will be replaced by CRLF in ...

The file will have its original line endings in your working directory.

Resolution:

$ git config --global core.autocrlf false     
$ git add --all 

No any warning messages come up.

I got this error when one of my properties that was required for the constructor was not public. Make sure all the parameters in the constructor go to properties that are public if this is the case:

using statements namespace someNamespace

public class ExampleClass {

  //Properties - one is not visible to the class calling the constructor
  public string Property1 { get; set; }
  string Property2 { get; set; }

   //Constructor
   public ExampleClass(string property1, string property2)
  {
     this.Property1 = property1;
     this.Property2 = property2;  //this caused that error for me
  }
}

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

The debate between cssSelector vs XPath would remain as one of the most subjective debate in the Selenium Community. What we already know so far can be summarized as:

• People in favor of cssSelector say that it is more readable and faster (especially when running against Internet Explorer).
• While those in favor of XPath tout it's ability to transverse the page (while cssSelector cannot).
• Traversing the DOM in older browsers like IE8 does not work with cssSelector but is fine with XPath.
• XPath can walk up the DOM (e.g. from child to parent), whereas cssSelector can only traverse down the DOM (e.g. from parent to child)
• However not being able to traverse the DOM with cssSelector in older browsers isn't necessarily a bad thing as it is more of an indicator that your page has poor design and could benefit from some helpful markup.
• Ben Burton mentions you should use cssSelector because that's how applications are built. This makes the tests easier to write, talk about, and have others help maintain.
• Adam Goucher says to adopt a more hybrid approach -- focusing first on IDs, then cssSelector, and leveraging XPath only when you need it (e.g. walking up the DOM) and that XPath will always be more powerful for advanced locators.

Dave Haeffner carried out a test on a page with two HTML data tables, one table is written without helpful attributes (ID and Class), and the other with them. I have analyzed the test procedure and the outcome of this experiment in details in the discussion Why should I ever use cssSelector selectors as opposed to XPath for automated testing?. While this experiment demonstrated that each Locator Strategy is reasonably equivalent across browsers, it didn't adequately paint the whole picture for us. Dave Haeffner in the other discussion Css Vs. X Path, Under a Microscope mentioned, in an an end-to-end test there were a lot of other variables at play Sauce startup, Browser start up, and latency to and from the application under test. The unfortunate takeaway from that experiment could be that one driver may be faster than the other (e.g. IE vs Firefox), when in fact, that's wasn't the case at all. To get a real taste of what the performance difference is between cssSelector and XPath, we needed to dig deeper. We did that by running everything from a local machine while using a performance benchmarking utility. We also focused on a specific Selenium action rather than the entire test run, and run things numerous times. I have analyzed the specific test procedure and the outcome of this experiment in details in the discussion cssSelector vs XPath for selenium. But the tests were still missing one aspect i.e. more browser coverage (e.g., Internet Explorer 9 and 10) and testing against a larger and deeper page.

Dave Haeffner in another discussion Css Vs. X Path, Under a Microscope (Part 2) mentions, in order to make sure the required benchmarks are covered in the best possible way we need to consider an example that demonstrates a large and deep page.

Test SetUp

To demonstrate this detailed example, a Windows XP virtual machine was setup and Ruby (1.9.3) was installed. All the available browsers and their equivalent browser drivers for Selenium was also installed. For benchmarking, Ruby's standard lib benchmark was used.

Results

NOTE: The output is in seconds, and the results are for the total run time of 100 executions.

In Table Form:

In Chart Form:

• Chrome:

• Firefox:

• Internet Explorer 8:

• Internet Explorer 9:

• Internet Explorer 10:

• Opera:

Analyzing the Results

• Chrome and Firefox are clearly tuned for faster cssSelector performance.
• Internet Explorer 8 is a grab bag of cssSelector that won't work, an out of control XPath traversal that takes ~65 seconds, and a 38 second table traversal with no cssSelector result to compare it against.
• In IE 9 and 10, XPath is faster overall. In Safari, it's a toss up, except for a couple of slower traversal runs with XPath. And across almost all browsers, the nested sibling traversal and table cell traversal done with XPath are an expensive operation.
• These shouldn't be that surprising since the locators are brittle and inefficient and we need to avoid them.

Summary

• Overall there are two circumstances where XPath is markedly slower than cssSelector. But they are easily avoidable.
• The performance difference is slightly in favor of css-selectors for non-IE browsers and slightly in favor of xpath for IE browsers.

Trivia

You can perform the bench-marking on your own, using this library where Dave Haeffner wrapped up all the code.

Do you just mean spaces or all whitespace?

For just spaces, use str_replace:

$string = str_replace(' ', '', $string);

For all whitespace (including tabs and line ends), use preg_replace:

$string = preg_replace('/\s+/', '', $string);

(From here).

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

❐ Using java.sql.Date

If your table has a column of type DATE:

• java.lang.String

  The method java.sql.Date.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d. e.g.:

  ps.setDate(2, java.sql.Date.valueOf("2013-09-04"));
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setDate(2, new java.sql.Date(endDate.getTime());
  

• Current

  If you want to insert the current date:

  ps.setDate(2, new java.sql.Date(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setDate(2, java.sql.Date.valueOf(java.time.LocalDate.now()));
  

❐ Using java.sql.Timestamp

If your table has a column of type TIMESTAMP or DATETIME:

• java.lang.String

  The method java.sql.Timestamp.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d hh:mm:ss[.f...]. e.g.:

  ps.setTimestamp(2, java.sql.Timestamp.valueOf("2013-09-04 13:30:00");
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setTimestamp(2, new java.sql.Timestamp(endDate.getTime()));
  

• Current

  If you require the current timestamp:

  ps.setTimestamp(2, new java.sql.Timestamp(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setTimestamp(2, java.sql.Timestamp.from(java.time.Instant.now()));
  ps.setTimestamp(2, java.sql.Timestamp.valueOf(java.time.LocalDateTime.now()));
  

You can use simple trick which is import flask app variable from main inside another file, like:

test-routes.py

from __main__ import app

@app.route('/test', methods=['GET'])
def test():
    return 'it works!'

and in your main files, where you declared flask app, import test-routes, like:

app.py

from flask import Flask, request, abort

app = Flask(__name__)

# import declared routes
import test-routes

It works from my side.

long start = System.currentTimeMillis();
long end = start + 60*1000; // 60 seconds * 1000 ms/sec
while (System.currentTimeMillis() < end)
{
    // run
}

The cc and cxx is located inside /Applications/Xcode.app. This should find the right paths

export CXX=`xcrun -find c++`
export CC=`xcrun -find cc`

Just in case someone else is looking for this answer, we had a similar problem and solved it by changing the z-index of the input tags. Apparently some other divs had extended too far and were overlapping the input boxes.

include them with this order this will work i dont know why :D

<!-- jQuery -->
<script src="js/jquery-3.4.1.min.js"></script>

<!-- Popper -->

<!-- Bootstrap js -->

You need to set both the user-agent and the referer:

 wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" --referrer  connect.wso2.com http://dist.wso2.org/products/carbon/4.2.0/wso2carbon-4.2.0.zip

...and when I got one how to process it (do I need to use Fourier Transform like it was instructed in the above post)?

If you want a "tap" then I think you are interested in amplitude more than frequency. So Fourier transforms probably aren't useful for your particular goal. You probably want to make a running measurement of the short-term (say 10 ms) amplitude of the input, and detect when it suddenly increases by a certain delta. You would need to tune the parameters of:

• what is the "short-term" amplitude measurement
• what is the delta increase you look for
• how quickly the delta change must occur

Although I said you're not interested in frequency, you might want to do some filtering first, to filter out especially low and high frequency components. That might help you avoid some "false positives". You could do that with an FIR or IIR digital filter; Fourier isn't necessary.

Yes, you can use the built-in hashlib module or the built-in hash function. Then, chop-off the last eight digits using modulo operations or string slicing operations on the integer form of the hash:

>>> s = 'she sells sea shells by the sea shore'

>>> # Use hashlib
>>> import hashlib
>>> int(hashlib.sha1(s.encode("utf-8")).hexdigest(), 16) % (10 ** 8)
58097614L

>>> # Use hash()
>>> abs(hash(s)) % (10 ** 8)
82148974

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

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)

Note: If you know Key, use this code

String value=meMap.get(key);

You can try this, it works for me.

 <input type="text"  onchange="CheckValidAmount(this.value)" name="amount" required>

 <script type="text/javascript">
    function CheckValidAmount(amount) {          
       var a = /^(?:\d{1,3}(?:,\d{3})*|\d+)(?:\.\d+)?$/;
       if(amount.match(a)){
           alert("matches");
       }else{
        alert("does not match"); 
       }
    }
</script>

You can cast it by doing (char *)Identifier_Of_Const_char

But as there is probabbly a reason that the api doesn't accept const cahr *, you should do this only, if you are sure, the function doesn't try to assign any value in range of your const char* which you casted to a non const one.

We just released pako https://github.com/nodeca/pako , port of zlib to javascript. I think that's now the fastest js implementation of deflate / inflate / gzip / ungzip. Also, it has democratic MIT licence. Pako supports all zlib options and it's results are binary equal.

Example:

var inflate = require('pako/lib/inflate').inflate; 
var text = inflate(zipped, {to: 'string'});

It does not work because sequence does not work in following scenarios:

• In a WHERE clause
• In a GROUP BY or ORDER BY clause
• In a DISTINCT clause
• Along with a UNION or INTERSECT or MINUS
• In a sub-query

Source: http://www.orafaq.com/wiki/ORA-02287

However this does work:

insert into table_name
            (col1, col2)
  select my_seq.nextval, inner_view.*
    from (select 'some value' someval
            from dual
          union all
          select 'another value' someval
            from dual) inner_view;

Try it out:

create table table_name(col1 varchar2(100), col2 varchar2(100));

create sequence vcert.my_seq
start with 1
increment by 1
minvalue 0;

select * from  table_name;

Axios

An example (axios_example.js) using Axios in Node.js:

const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

app.get('/search', function(req, res) {
    let query = req.query.queryStr;
    let url = `https://your.service.org?query=${query}`;

    axios({
        method:'get',
        url,
        auth: {
            username: 'the_username',
            password: 'the_password'
        }
    })
    .then(function (response) {
        res.send(JSON.stringify(response.data));
    })
    .catch(function (error) {
        console.log(error);
    });
});

var server = app.listen(port);

Be sure in your project directory you do:

npm init
npm install express
npm install axios
node axios_example.js

You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx

Similarly you can do post, such as:

axios({
  method: 'post',
  url: 'https://your.service.org/user/12345',
  data: {
    firstName: 'Fred',
    lastName: 'Flintstone'
  }
});

SuperAgent

Similarly you can use SuperAgent.

superagent.get('https://your.service.org?query=xxxx')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

And if you want to do basic authentication:

superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

It would be the 32 bit version of eclipse , for instance if you are running the 32 bit version of eclipse in 64 bit JVM, this error will be the result.

To confirm this check for log in your configuration folder of the eclipse. Log will be as following java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM ...

try installing the either 64 bit eclipse or run in 32 bit jvm

Try this

button.addTarget(self, action:#selector(handleRegister()), for: .touchUpInside). 

Just add parenthesis with name of method.

Also you can refer link : Value of type 'CustomButton' has no member 'touchDown'

when you are using 32bits node on 64bits windows(like node-webkit or atom-shell developers), process.platform will echo win32

use

    function isOSWin64() {
      return process.arch === 'x64' || process.env.hasOwnProperty('PROCESSOR_ARCHITEW6432');
    }

Compilr is an online java compiler. It provides syntax highlighting and reports any errors back to you. It's a project I'm working on, so if you have any feedback please leave a comment!

If you are building your project with gradle, you just need to add one line to the dependencies in the build.gradle:

buildscript {
    ...
}
...

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}

and then add the folder to your root project or module:

Then you drop your jars in there and you are good to go :-)

I have had this error.And my solution is following as:

1. Create a custom listview which is non scrollable

public class NonScrollListView extends ListView {

public NonScrollListView(Context context) {
    super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
    super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();    
}

}

2. Use above custom class for xml file

  <com.Example.NonScrollListView
        android:id="@+id/lv_nonscroll_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </com.Example.NonScrollListView>

Hope best for you.

I found two pages that seem helpful, it's written for ASP.Net, but the same stuff should apply:

1. How to add/remove items from a dropdown list using jQuery
2. jQuery selector expressions

Try adding these two lines to your code. I hope it will work. It worked for me :)

display.setLineWrap(true);
display.setWrapStyleWord(true);

Picture of output is shown below

Declare the variable as a static and reference it in the required method using className.variable

It's a modulo operation, except when it's an old-fashioned C-style string formatting operator, not a modulo operation. See here for details. You'll see a lot of this in existing code.

react-tidy has a custom hook just for doing that called useRefresh:

import React from 'react'
import {useRefresh} from 'react-tidy'

function App() {
  const refresh = useRefresh()
  return (
    <p>
      The time is {new Date()} <button onClick={refresh}>Refresh</button>
    </p>
  )
}

Follow the above steps to open the database folder of your app in Android Device explorer and in there you can see six files, The first three is named as android and the last three is named as your database name. You only have to work with the last three files, save these three files at your preferred location. You can save these files by right-clicking to the file and click save as button (like I have my database named as room_database and so three files are named as room_database, room_database-shm, and room_database-wal. Rename the corresponding file as follows:-

1) room_database to room_database.db 2) room_database-shm to room_database.db-shm 3) room_database-wal to room_database.db-wal

Now open the 1st file in any SQLite browser and all the three files will be populated in the browser.

I've tested the performance of all the proposed approaches.

Here is the fastest variant I've got.

String.prototype.repeat = function(count) {
    if (count < 1) return '';
    var result = '', pattern = this.valueOf();
    while (count > 1) {
        if (count & 1) result += pattern;
        count >>= 1, pattern += pattern;
    }
    return result + pattern;
};

Or as stand-alone function:

function repeat(pattern, count) {
    if (count < 1) return '';
    var result = '';
    while (count > 1) {
        if (count & 1) result += pattern;
        count >>= 1, pattern += pattern;
    }
    return result + pattern;
}

It is based on artistoex algorithm. It is really fast. And the bigger the count, the faster it goes compared with the traditional new Array(count + 1).join(string) approach.

I've only changed 2 things:

1. replaced pattern = this with pattern = this.valueOf() (clears one obvious type conversion);
2. added if (count < 1) check from prototypejs to the top of function to exclude unnecessary actions in that case.
3. applied optimisation from Dennis answer (5-7% speed up)

UPD

Created a little performance-testing playground here for those who interested.

variable count ~ 0 .. 100:

constant count = 1024:

Use it and make it even faster if you can :)

Try the following:

import time
timeout = time.time() + 60*5   # 5 minutes from now
while True:
    test = 0
    if test == 5 or time.time() > timeout:
        break
    test = test - 1

You may also want to add a short sleep here so this loop is not hogging CPU (for example time.sleep(1) at the beginning or end of the loop body).

remove the range.

for i in myList

range takes in an integer. you want for each element in the list.

• Wrap radio and image in <label>
• Hide radio button (Don't use display:none or visibility:hidden since such will impact accessibility)
• Target the image next to the hidden radio using Adjacent sibling selector +

/* HIDE RADIO */

  position: absolute;
  opacity: 0;
  width: 0;
  height: 0;
}

/* IMAGE STYLES */
[type=radio] + img {

List list = ..;

String [] stringArray = list.toArray(new String[list.size()]);

great answer from here: https://stackoverflow.com/a/4042464/1547266

As of python 3.2, using only standard library functions:

u_tm = datetime.datetime.utcfromtimestamp(0)
l_tm = datetime.datetime.fromtimestamp(0)
l_tz = datetime.timezone(l_tm - u_tm)

t = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=l_tz)
str(t)
'2009-07-10 18:44:59.193982-07:00'

Just need to use l_tm - u_tm or u_tm - l_tm depending whether you want to show as + or - hours from UTC. I am in MST, which is where the -07 comes from. Smarter code should be able to figure out which way to subtract.

And only need to calculate the local timezone once. That is not going to change. At least until you switch from/to Daylight time.

If the contained type of the Set is an enumeration then there is java built factory method (since 1.5):

Set<MY_ENUM> MY_SET = EnumSet.of( MY_ENUM.value1, MY_ENUM.value2, ... );

SELECT * FROM persons WHERE (`LastName` LIKE 'r%') OR (`FirstName` LIKE 'a%');

Please try with above query.

It is an attribute, but a boolean one (so it doesn't need a name, just a value -- I know, it's weird). You can set the property equivalent in Javascript:

document.getElementsByName("myButton")[0].disabled = true;

Good solution from bmu. I think it's more readable to put the values inside the parentheses vs outside.

    df['Values'] = np.where(df.Action == 'Sell', 
                            df.Prices*df.Amount, 
                           -df.Prices*df.Amount)

Using some pandas built in functions.

    df['Values'] = np.where(df.Action.eq('Sell'), 
                            df.Prices.mul(df.Amount), 
                           -df.Prices.mul(df.Amount))

In the HTTP request you need to set Content-Type to: Content-Type: application/json

So if you're using fiddler client add Content-Type: application/json to the request header

What you have written in your sql string is a Timestamp not Date. You must convert it to Date or change type of database field to Timestamp for it to be seen correctly.

Just wanted to point out that the built-in sink function has good examples of different ways to set arguments in a function:

> sink
function (file = NULL, append = FALSE, type = c("output", "message"),
    split = FALSE)
{
    type <- match.arg(type)
    if (type == "message") {
        if (is.null(file))
            file <- stderr()
        else if (!inherits(file, "connection") || !isOpen(file))
            stop("'file' must be NULL or an already open connection")
        if (split)
            stop("cannot split the message connection")
        .Internal(sink(file, FALSE, TRUE, FALSE))
    }
    else {
        closeOnExit <- FALSE
        if (is.null(file))
            file <- -1L
        else if (is.character(file)) {
            file <- file(file, ifelse(append, "a", "w"))
            closeOnExit <- TRUE
        }
        else if (!inherits(file, "connection"))
            stop("'file' must be NULL, a connection or a character string")
        .Internal(sink(file, closeOnExit, FALSE, split))
    }
}

Or by direct string access:

$string[strlen($string)-1];

Note that this doesn't work for multibyte strings. If you need to work with multibyte string, consider using the mb_* string family of functions.

As of PHP 7.1.0 negative numeric indices are also supported, e.g just $string[-1];

You can create files in browser using Blob and URL.createObjectURL. All recent browsers support this.

You can not directly save the file you create, since that would cause massive security problems, but you can provide it as a download link for the user. You can suggest a file name via the download attribute of the link, in browsers that support the download attribute. As with any other download, the user downloading the file will have the final say on the file name though.

var textFile = null,
  makeTextFile = function (text) {
    var data = new Blob([text], {type: 'text/plain'});

    // If we are replacing a previously generated file we need to
    // manually revoke the object URL to avoid memory leaks.
    if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }

    textFile = window.URL.createObjectURL(data);

    // returns a URL you can use as a href
    return textFile;
  };

Here's an example that uses this technique to save arbitrary text from a textarea.

If you want to immediately initiate the download instead of requiring the user to click on a link, you can use mouse events to simulate a mouse click on the link as Lifecube's answer did. I've created an updated example that uses this technique.

  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');

  create.addEventListener('click', function () {
    var link = document.createElement('a');
    link.setAttribute('download', 'info.txt');
    link.href = makeTextFile(textbox.value);
    document.body.appendChild(link);

    // wait for the link to be added to the document
    window.requestAnimationFrame(function () {
      var event = new MouseEvent('click');
      link.dispatchEvent(event);
      document.body.removeChild(link);
    });

  }, false);

var map:Map[String, String] = Map()

var map1 = map + ("red" -> "#FF0000")

println(map1)

I've also found that if you had display:none, then programmatically changed it to be visible, you might also have to set

$tr.css({display:'table-row'});

rather than display:inline or display:block otherwise the cell might only show as taking up 1 cell, no matter how large you have the colspan set to.

Well I did not think this was possible until I went and checked. In some previous version of Excel I could not do this. I am currently using Excel 2013.

This is what you want to do in a scatter plot:

1. right click on your data point

2. select "Format Data Labels" (note you may have to add data labels first)

3. put a check mark in "Values from Cells"
4. click on "select range" and select your range of labels you want on the points

UPDATE: Colouring Individual Labels

In order to colour the labels individually use the following steps:

1. select a label. When you first select, all labels for the series should get a box around them like the graph above.
2. Select the individual label you are interested in editing. Only the label you have selected should have a box around it like the graph below.
3. On the right hand side, as shown below, Select "TEXT OPTIONS".
4. Expand the "TEXT FILL" category if required.
5. Second from the bottom of the category list is "COLOR", select the colour you want from the pallet.

If you have the entire series selected instead of the individual label, text formatting changes should apply to all labels instead of just one.

This trick worked for me in Eclipse Luna (4.4.2): For a jar file I am using (htsjdk), I packed the source in a separate jar file (named htsjdk-2.0.1-src.jar; I could do this since htsjdk is open source) and stored it in the lib-src folder of my project. In my own Java source I selected an element I was using from the jar and hit F3 (Open declaration). Eclipse opened the class file and showed the button "Attach source". I clicked the button and pointed to the src jar file I had just put into the lib-src folder. Now I get the Javadoc when hovering over anything I’m using from the jar.

Yes. In fact Axel Schreiner provides his book "Object-oriented Programming in ANSI-C" for free which covers the subject quite thoroughly.

Here's an extension that will do it all, on as many elements in as many ways...

Example usage:

keep existing class and attributes:

$('div#change').replaceTag('<span>', true);

or

Discard existing class and attributes:

$('div#change').replaceTag('<span class=newclass>', false);

or even

replace all divs with spans, copy classes and attributes, add extra class name

$('div').replaceTag($('<span>').addClass('wasDiv'), true);

Plugin Source:

$.extend({
    replaceTag: function (currentElem, newTagObj, keepProps) {
        var $currentElem = $(currentElem);
        var i, $newTag = $(newTagObj).clone();
        if (keepProps) {//{{{
            newTag = $newTag[0];
            newTag.className = currentElem.className;
            $.extend(newTag.classList, currentElem.classList);
            $.extend(newTag.attributes, currentElem.attributes);
        }//}}}
        $currentElem.wrapAll($newTag);
        $currentElem.contents().unwrap();
        // return node; (Error spotted by Frank van Luijn)
        return this; // Suggested by ColeLawrence
    }
});

$.fn.extend({
    replaceTag: function (newTagObj, keepProps) {
        // "return" suggested by ColeLawrence
        return this.each(function() {
            jQuery.replaceTag(this, newTagObj, keepProps);
        });
    }
});

Try

body {
    margin: 0;
    padding: 0;
}

instead of

.body {
    margin: 0;
    padding: 0;
}

Do not select body with class selector.

for (Project project : listOfLists) {
    String nama_project = project.getNama_project();
    if (project.getModelproject().size() > 1) {
        for (int i = 1; i < project.getModelproject().size(); i++) {
            DataModel model = project.getModelproject().get(i);
            int id_laporan = model.getId();
            String detail_pekerjaan = model.getAlamat();
        }
    }
}

set height: auto; If you want to have minimum height to x then you can write

height:auto;
min-height:30px;
height:auto !important;        /* for IE as it does not support min-height */
height:30px;                   /* for IE as it does not support min-height */

The current lib.d.ts doesn't have promises in it defined so you need a extra definition file for it that is why you are getting compilation errors.

You could for example use (like @elclanrs says) use the es6-promise package with the definition file from DefinitelyTyped: es6-promise definition

You can then use it like this:

var p = new Promise<string>((resolve, reject) => { 
    resolve('a string'); 
});

edit You can use it without a definition when targeting ES6 (with the TypeScript compiler) - Note you still require the Promise to exists in the runtime ofcourse (so it won't work in old browsers :)) Add/Edit the following to your tsconfig.json :

"compilerOptions": {
    "target": "ES6"
}

edit 2 When TypeScript 2.0 will come out things will change a bit (though above still works) but definition files can be installed directly with npm like below:

npm install --save @types/es6-promise - source

edit3 Updating answer with more info for using the types.

Create a package.json file with only { } as the content (if you don't have a package.json already. Call npm install --save @types/es6-promise and tsc --init. The first npm install command will change your package.json to include the es6-promise as a dependency. tsc --init will create a tsconfig.json file for you.

You can now use the promise in your typescript file var x: Promise<any>;. Execute tsc -p . to compile your project. You should have no errors.

public static string GetTempFileName(string extension)
{
  int attempt = 0;
  while (true)
  {
    string fileName = Path.GetRandomFileName();
    fileName = Path.ChangeExtension(fileName, extension);
    fileName = Path.Combine(Path.GetTempPath(), fileName);

    try
    {
      using (new FileStream(fileName, FileMode.CreateNew)) { }
      return fileName;
    }
    catch (IOException ex)
    {
      if (++attempt == 10)
        throw new IOException("No unique temporary file name is available.", ex);
    }
  }
}

Note: this works like Path.GetTempFileName. An empty file is created to reserve the file name. It makes 10 attempts, in case of collisions generated by Path.GetRandomFileName();

You cannot move a running docker container from one host to another.

You can commit the changes in your container to an image with docker commit, move the image onto a new host, and then start a new container with docker run. This will preserve any data that your application has created inside the container.

Nb: It does not preserve data that is stored inside volumes; you need to move data volumes manually to new host.

With pure HTML you can't influence this - every modern browser (= the user) has complete control over this behavior because it has been misused a lot in the past...

HTML option

You can open a new window (HTML4) or a new browsing context (HTML5). Browsing context in modern browsers is mostly "new tab" instead of "new window". You have no influence on that, and you can't "force" modern browsers to open a new window.

In order to do this, use the anchor element's attribute target^[1]. The value you are looking for is _blank^[2].

<a href="www.example.com/example.html" target="_blank">link text</a>

JavaScript option

Forcing a new window is possible via javascript - see Ievgen's excellent answer below for a javascript solution.

(!) However, be aware, that opening windows via javascript (if not done in the onclick event from an anchor element) are subject to getting blocked by popup blockers!

_{[1] This attribute dates back to the times when browsers did not have tabs and using framesets was state of the art. In the meantime, the functionality of this attribute has slightly changed (see MDN Docu)}

_{[2] There are some other values which do not make much sense anymore (because they were designed with framesets in mind) like _parent, _self or _top.}

intList = Array.ConvertAll(stringList, int.Parse).ToList();

Some other alternatives for copying ArrayList as a Deep Copy

Alernative 1 - Use of external package commons-lang3, method SerializationUtils.clone():

SerializationUtils.clone()

Let's say we have a class dog where the fields of the class are mutable and at least one field is an object of type String and mutable - not a primitive data type (otherwise shallow copy would be enough).

Example of shallow copy:

List<Dog> dogs = getDogs(); // We assume it returns a list of Dogs
List<Dog> clonedDogs = new ArrayList<>(dogs);

Now back to deep copy of dogs.

The Dog class does only have mutable fields.

Dog class:

public class Dog implements Serializable {
    private String name;
    private int age;

    public Dog() {
        // Class with only mutable fields!
        this.name = "NO_NAME";
        this.age = -1;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Dog{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

Note that the class Dog implements Serializable! This makes it possible to utilize method "SerializationUtils.clone(dog)"

Read the comments in the main method to understand the outcome. It shows that we have successfully made a deep copy of ArrayList(). See below "SerializationUtils.clone(dog)" in context:

public static void main(String[] args) {
    Dog dog1 = new Dog();
    dog1.setName("Buddy");
    dog1.setAge(1);

    Dog dog2 = new Dog();
    dog2.setName("Milo");
    dog2.setAge(2);

    List<Dog> dogs = new ArrayList<>(Arrays.asList(dog1,dog2));

    // Output: 'List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]'
    System.out.println("List dogs: " + dogs);

    // Let's clone and make a deep copy of the dogs' ArrayList with external package commons-lang3:
    List<Dog> clonedDogs = dogs.stream().map(dog -> SerializationUtils.clone(dog)).collect(Collectors.toList());
    // Output: 'Now list dogs are deep copied into list clonedDogs.'
    System.out.println("Now list dogs are deep copied into list clonedDogs.");

    // A change on dog1 or dog2 can not impact a deep copy.
    // Let's make a change on dog1 and dog2, and test this
    // statement.
    dog1.setName("Bella");
    dog1.setAge(3);
    dog2.setName("Molly");
    dog2.setAge(4);

    // The change is made on list dogs!
    // Output: 'List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]'
    System.out.println("List dogs after change: " + dogs);

    // There is no impact on list clonedDogs's inner objects after the deep copy.
    // The deep copy of list clonedDogs was successful!
    // If clonedDogs would be a shallow copy we would see the change on the field
    // "private String name", the change made in list dogs, when setting the names
    // Bella and Molly.
    // Output clonedDogs:
    // 'After change in list dogs, no impact/change in list clonedDogs:\n'
    // '[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]\n'
    System.out.println("After change in list dogs, no impact/change in list clonedDogs: \n" + clonedDogs);
}

Output:

List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Now list dogs are deep copied into list clonedDogs.
List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]
After change in list dogs, no impact/change in list clonedDogs:
[Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]

Comment: Since there is no impact/change on list clonedDogs after changing list dogs, then deep copy of ArrayList is successful!

Alernative 2 - Use of no external packages:

A new method "clone()" is introduced in the Dog class and "implements Serializable" is removed compare to alternative 1.

clone()

Dog class:

public class Dog {
    private String name;
    private int age;

    public Dog() {
        // Class with only mutable fields!
        this.name = "NO_NAME";
        this.age = -1;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    /**
     * Returns a deep copy of the Dog
     * @return new instance of {@link Dog}
     */
    public Dog clone() {
        Dog newDog = new Dog();
        newDog.setName(this.name);
        newDog.setAge(this.age);
        return newDog;
    }

    @Override
    public String toString() {
        return "Dog{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

}

Output:

List dogs: [Dog{name='Buddy', age=1}, Dog{name='Milo', age=2}]
Now list dogs are deep copied into list clonedDogs.
List dogs after change: [Dog{name='Bella', age=3}, Dog{name='Molly', age=4}]

Comment: Since there is no impact/change on list clonedDogs after changing list dogs, then deep copy of ArrayList is successful!

Note1: Alternative 1 is much slower than Alternative 2, but easier to mainatain since you do not need to upadate any methods like clone().

Note2: For alternative 1 the following maven dependency was used for method "SerializationUtils.clone()":

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
<dependency>
    <groupId>org.apache.commons</groupId>

As others have already mentioned, running PHP as a daemon is quite easy, and can be done using a single line of command. But the actual problem is keeping it running and managing it. I've had the same problem quite some time ago and although there are plenty of solutions already available, most of them have lots of dependencies or are difficult to use and not suitable for basic usages. I wrote a shell script that can manage a any process/application including PHP cli scripts. It can be set as a cronjob to start the application and will contain the application and manage it. If it's executed again, for example via the same cronjob, it check if the app is running or not, if it does then simply exits and let its previous instance continue managing the application.

I uploaded it to github, feel free to use it : https://github.com/sinasalek/EasyDeamonizer

EasyDeamonizer

Simply watches over your application (start, restart, log, monitor, etc). a generic script to make sure that your appliation remains running properly. Intentionally it uses process name instread of pid/lock file to prevent all its side effects and keep the script as simple and as stirghforward as possible, so it always works even when EasyDaemonizer itself is restarted. Features

• Starts the application and optionally a customized delay for each start
• Makes sure that only one instance is running
• Monitors CPU usage and restarts the app automatically when it reaches the defined threshold
• Setting EasyDeamonizer to run via cron to run it again if it's halted for any reason
• Logs its activity

A library implements functionality for a narrowly-scoped purpose whereas a framework tends to be a collection of libraries providing support for a wider range of features. For example, the library System.Drawing.dll handles drawing functionality, but is only one part of the overall .NET framework.

Yes, a menu gives you the bar but it doesn't give you any items to put in the bar. You need something like (from one of my own projects):

<!-- Menu. -->
<Menu Width="Auto" Height="20" Background="#FFA9D1F4" DockPanel.Dock="Top">
    <MenuItem Header="_Emulator">
    <MenuItem Header="Load..." Click="MenuItem_Click" />
    <MenuItem Header="Load again" Click="menuEmulLoadLast" />
    <Separator />
    <MenuItem Click="MenuItem_Click">
        <MenuItem.Header>
            <DockPanel>
                <TextBlock>Step</TextBlock>
                <TextBlock Width="10"></TextBlock>
                <TextBlock HorizontalAlignment="Right">F2</TextBlock>

The following solution to a struct is inspired by the namedtuple implementation and some of the previous answers. However, unlike the namedtuple it is mutable, in it's values, but like the c-style struct immutable in the names/attributes, which a normal class or dict isn't.

_class_template = """\
class {typename}:
def __init__(self, *args, **kwargs):
    fields = {field_names!r}

    for x in fields:
        setattr(self, x, None)            

    for name, value in zip(fields, args):
        setattr(self, name, value)

    for name, value in kwargs.items():
        setattr(self, name, value)            

def __repr__(self):
    return str(vars(self))

def __setattr__(self, name, value):
    if name not in {field_names!r}:
        raise KeyError("invalid name: %s" % name)
    object.__setattr__(self, name, value)            
"""

def struct(typename, field_names):

    class_definition = _class_template.format(
        typename = typename,
        field_names = field_names)

    namespace = dict(__name__='struct_%s' % typename)
    exec(class_definition, namespace)
    result = namespace[typename]
    result._source = class_definition

    return result

Usage:

Person = struct('Person', ['firstname','lastname'])
generic = Person()
michael = Person('Michael')
jones = Person(lastname = 'Jones')


In [168]: michael.middlename = 'ben'
Traceback (most recent call last):

There are several possible causes.

1. The other end has deliberately reset the connection, in a way which I will not document here. It is rare, and generally incorrect, for application software to do this, but it is not unknown for commercial software.

2. More commonly, it is caused by writing to a connection that the other end has already closed normally. In other words an application protocol error.

3. It can also be caused by closing a socket when there is unread data in the socket receive buffer.

4. In Windows, 'software caused connection abort', which is not the same as 'connection reset', is caused by network problems sending from your end. There's a Microsoft knowledge base article about this.

You can use this regex to get the yyyy-MM-dd format:

((?:19|20)\\d\\d)-(0?[1-9]|1[012])-([12][0-9]|3[01]|0?[1-9])

You can find example for date validation: How to validate date with regular expression.

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

You can use $_SERVER['HTTP_REFERER'] this will give you whole URL for example:

suppose you want to get url of site name www.example.com then $_SERVER['HTTP_REFERER'] will give you https://www.example.com

You have to export it from your NgModule:

@NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule],
  providers: []
})
export class TaskModule{}

Best practice is to define variable as an array at the very top of your code.

foreach((array)$myArr as $oneItem) { .. }

will also work but you will duplicate this (array) conversion everytime you need to loop through the array.

since it's important not to duplicate even a word of your code, you do better to define it as an empty array at top.

A little late here, but I've found this to be a common problem worth a custom directive to handle. Here's how that might look:

  .directive('toggleOnHover', function(){
    return {
      restrict: 'A',
      link: link
    };

    function link(scope, elem, attrs){
      elem.on('mouseenter', applyToggleExp);
      elem.on('mouseleave', applyToggleExp);

      function applyToggleExp(){
        scope.$apply(attrs.toggleOnHover);
      }
    }

  });

You can use it like this:

<li toggle-on-hover="editableProp = !editableProp">edit</li> 

Simplest and best:

i = 0
while not there_is_reason_to_break(i):
    # some code here
    i += 1

It may be tempting to choose the closest analogy to the C code possible in Python:

from itertools import count

for i in count():
    if thereIsAReasonToBreak(i):
        break

But beware, modifying i will not affect the flow of the loop as it would in C. Therefore, using a while loop is actually a more appropriate choice for porting that C code to Python.

OpenTURNS allows to not only simulate the random integers but also to define the associated distribution with the UserDefined defined class.

The following simulates 12 outcomes of the distribution.

import openturns as ot
points = [[i] for i in range(10)]
distribution = ot.UserDefined(points) # By default, with equal weights.
for i in range(12):
    x = distribution.getRealization()
    print(i,x)

This prints:

0 [8]
1 [7]
2 [4]
3 [7]
4 [3]
5 [3]
6 [2]
7 [9]
8 [0]
9 [5]
10 [9]
11 [6]

The brackets are there becausex is a Point in 1-dimension. It would be easier to generate the 12 outcomes in a single call to getSample:

sample = distribution.getSample(12)

would produce:

>>> print(sample)
     [ v0 ]
 0 : [ 3  ]
 1 : [ 9  ]
 2 : [ 6  ]
 3 : [ 3  ]
 4 : [ 2  ]
 5 : [ 6  ]
 6 : [ 9  ]
 7 : [ 5  ]
 8 : [ 9  ]
 9 : [ 5  ]
10 : [ 3  ]
11 : [ 2  ]

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

Assuming $WORKING_DIR is set to the directory... this one-liner should do it:

if [ -d "$WORKING_DIR" ]; then rm -Rf $WORKING_DIR; fi

(otherwise just replace with your directory)

There is no documented /prompt parameter for SETX as there is for SET.

If you need to prompt for an environment variable that will survive reboots, you can use SETX to store it.

A variable created by SETX won't be usable until you restart the command prompt. Neatly, however, you can SETX a variable that has already been SET, even if it has the same name.

This works for me in Windows 8.1 Pro:

set /p UserInfo= "What is your name?  "
setx UserInfo "%UserInfo%"

(The quotation marks around the existing variable are necessary.)

This procedure allows you to use the temporary SET-created variable during the current session and will allow you to reuse the SETX-created variable upon reboot of the computer or restart of the CMD prompt.

Here is an updated answer for iOS7+. It uses NSURLSession, the new hotness. Disclaimer, this is untested and was written in a text field:

- (void)post {
    NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:nil];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://example.com/dontposthere"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    // Uncomment the following two lines if you're using JSON like I imagine many people are (the person who is asking specified plain text)
    // [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    // [request addValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [request setHTTPMethod:@"POST"];
    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    }];
    [postDataTask resume];
}

-(void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(    NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler {
    completionHandler(NSURLSessionAuthChallengeUseCredential, [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]);
}

Or better yet, use AFNetworking 2.0+. Usually I would subclass AFHTTPSessionManager, but I'm putting this all in one method to have a concise example.

- (void)post {
    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:@"https://example.com"]];
    // Many people will probably want [AFJSONRequestSerializer serializer];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    // Many people will probably want [AFJSONResponseSerializer serializer];
    manager.responseSerializer = [AFHTTPRequestSerializer serializer];
    manager.securityPolicy.allowInvalidCertificates = NO; // Some servers require this to be YES, but default is NO.
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"username" password:@"password"];
    [[manager POST:@"dontposthere" parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"darn it");
    }] resume];
}

If you are using the JSON response serializer, the responseObject will be object from the JSON response (often NSDictionary or NSArray).

You got to add python to your PATH variable. One thing you can do is Edit your Path variable now and add

;%PYTHON%;

Your variable PYTHON should point to the root directory of your python installation.

For developers using the Fetch API in a Node.js app, this is how I got this to work using rejectUnauthorized.

Keep in mind that using rejectUnauthorized is dangerous as it opens you up to potential security risks, as it circumvents a problematic certificate.

const fetch = require("node-fetch");
const https = require('https');

const httpsAgent = new https.Agent({
  rejectUnauthorized: false,
});

async function getData() {
  const resp = await fetch(
    "https://myexampleapi.com/endpoint",
    {
      agent: httpsAgent,
    },
  )
  const data = await resp.json()
  return data
}

@Carlo I really like your implementation of this, but I wanted to share my version and how to use it in my ViewModel

First implement ICommand

public class Command : ICommand
{
    public delegate void ICommandOnExecute();
    public delegate bool ICommandOnCanExecute();

    private ICommandOnExecute _execute;
    private ICommandOnCanExecute _canExecute;

    public Command(ICommandOnExecute onExecuteMethod, ICommandOnCanExecute onCanExecuteMethod = null)
    {
        _execute = onExecuteMethod;
        _canExecute = onCanExecuteMethod;
    }

    #region ICommand Members

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute?.Invoke() ?? true;
    }

    public void Execute(object parameter)
    {
        _execute?.Invoke();
    }

    #endregion
}

Notice I have removed the parameter from ICommandOnExecute and ICommandOnCanExecute and added a null to the constructor

Then to use in the ViewModel

public Command CommandToRun_WithCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        }, () =>
        {
            // Code to check to see if we can run 
            // Return true or false
        });
    }
}

public Command CommandToRun_NoCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        });
    }
}

I just find this way cleaner as I don't need to assign variables and then instantiate, it all done in one go.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

Use grep or grepl to find observations with white spaces and sub to get rid of them.

names<-c("Ganga Din\t", "Shyam Lal", "Bulbul ")
grep("[[:space:]]+$", names)
[1] 1 3
grepl("[[:space:]]+$", names)
[1]  TRUE FALSE  TRUE
sub("[[:space:]]+$", "", names)
[1] "Ganga Din" "Shyam Lal" "Bulbul"

Using execComand:

<input type="button" name="save" value="Save" onclick="javascript:document.execCommand('SaveAs','true','your_file.txt')">

In the next link: execCommand

LocalLinks now seems to be obsolete.

LocalExplorer seems to have taken it's place and provides similar functionality:

https://chrome.google.com/webstore/detail/local-explorer-file-manag/eokekhgpaakbkfkmjjcbffibkencdfkl/reviews?hl=en

It's basically a chrome plugin that replaces file:// links with localexplorer:// links, combined with an installable protocol handler that intercepts localexplorer:// links.

Best thing I can find available right now, I have no affiliation with the developer.

In regards to JavaScript:

The === operator works the same as the == operator, but it requires that its operands have not only the same value, but also the same data type.

For example, the sample below will display 'x and y are equal', but not 'x and y are identical'.

var x = 4;
var y = '4';
if (x == y) {
    alert('x and y are equal');
}
if (x === y) {
    alert('x and y are identical');
}

Combining all answers above, you can write reusable code with BaseEntity:

@Data
@NoArgsConstructor
@MappedSuperclass
public abstract class BaseEntity {

  @Transient
  public static final Sort SORT_BY_CREATED_AT_DESC = 
                        Sort.by(Sort.Direction.DESC, "createdAt");

  @Id
  private Long id;
  private LocalDateTime createdAt;
  private LocalDateTime updatedAt;

  @PrePersist
  void prePersist() {
    this.createdAt = LocalDateTime.now();
  }

  @PreUpdate
  void preUpdate() {
    this.updatedAt = LocalDateTime.now();
  }
}

DAO object overloads findAll method - basically, still uses findAll()

public interface StudentDAO extends CrudRepository<StudentEntity, Long> {

  Iterable<StudentEntity> findAll(Sort sort);

}

StudentEntity extends BaseEntity which contains repeatable fields (maybe you want to sort by ID, as well)

@Getter
@Setter
@FieldDefaults(level = AccessLevel.PRIVATE)
@Entity
class StudentEntity extends BaseEntity {

  String firstName;
  String surname;

}

Finally, the service and usage of SORT_BY_CREATED_AT_DESC which probably will be used not only in the StudentService.

@Service
class StudentService {

  @Autowired
  StudentDAO studentDao;

  Iterable<StudentEntity> findStudents() {
    return this.studentDao.findAll(SORT_BY_CREATED_AT_DESC);
  }
}

I spent whole my day figuring out this and found the following. And it works great now.

This is basically an issue with your gateway or proxy, If you are under proxy network, Please go to the network settings and set the proxy server settings(server, port , user name and password). If you are under direct gateway network, your firewall may be blocking the http get request from your eclipse.

Another way that skips even numbers after 2 is handled:

def prime_factors(n):
   factors = []
   d    = 2
   step = 1
   while d*d <= n:
      while n>1:
         while n%d == 0:
            factors.append(d)
            n = n/d
        d += step
        step = 2

  return factors

Python doesn't have an sscanf equivalent built-in, and most of the time it actually makes a whole lot more sense to parse the input by working with the string directly, using regexps, or using a parsing tool.

Probably mostly useful for translating C, people have implemented sscanf, such as in this module: http://hkn.eecs.berkeley.edu/~dyoo/python/scanf/

In this particular case if you just want to split the data based on multiple split characters, re.split is really the right tool.

I had the same problem with Visio 2016. I have the standard license. I think it is very strange that you can select a "UML Sequence" template when you search for it but it then opens a blank canvas without shapes. So you don't see anything and can't select the shapes under the "More Shapes" window on the side.

So I searched the shapes in the installation directory of Visio. I found in the directory C:\Program Files\Microsoft Office\Office16\Visio Content\1033 a couple of Sequence diagram templates (ie: BASIC_UMLSEQUENCE_M.VSTX). They are using the stencil USEQME_M.vssx. I found that out by right clicking the shapes in the left window and select "Save as". I saved them in "My Documents" under "My Shapes" just like custom shapes. I can than use them in any new document that I want.

Note the capital M or U in the name of the template or stencil for US Units or Metric Units. I'm from the Netherlands so I'm using the M version.

A not really friendly way to get the shapes. But it works.

Here's my attempt at the most forgiving string to bool conversion that is still useful, basically keying off only the first character.

public static class StringHelpers
{
    /// <summary>
    /// Convert string to boolean, in a forgiving way.
    /// </summary>
    /// <param name="stringVal">String that should either be "True", "False", "Yes", "No", "T", "F", "Y", "N", "1", "0"</param>
    /// <returns>If the trimmed string is any of the legal values that can be construed as "true", it returns true; False otherwise;</returns>
    public static bool ToBoolFuzzy(this string stringVal)
    {
        string normalizedString = (stringVal?.Trim() ?? "false").ToLowerInvariant();
        bool result = (normalizedString.StartsWith("y") 
            || normalizedString.StartsWith("t")
            || normalizedString.StartsWith("1"));
        return result;
    }
}

ProcessBuilder is very easy to use.

ProcessBuilder pb = new ProcessBuilder("python","Your python file",""+Command line arguments if any);
Process p = pb.start();

This should call python. Refer to the process approach here for full example!

https://bytes.com/topic/python/insights/949995-three-ways-run-python-programs-java

In the elements tab, right click the html node > copy > copy element - then paste into an editor.

As has been mentioned above, once the source has been converted into a DOM tree, the original source no longer exists in the browser. Any changes you make will be to the DOM, not the source.

However, you can parse the modified DOM back into HTML, letting you see the "generated source".

1. In Chrome, open the developer tools and click the elements tab.
2. Right click the HTML element.
3. Choose copy > copy element.
4. Paste into an editor.

You can now see the current DOM as an HTML page.

This is not the full DOM

Note that the DOM cannot be fully represented by an HTML document. This is because the DOM has many more properties than the HTML has attributes. However this will do a reasonable job.

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

http://docs.python.org/2/howto/unicode.html

@Aditya's answer is great, but there are instances where formatting will be thrown off if the very first cell of the row (for row background formatting) has a missing value (in complex tablixes with column/rows groups and missing values).

@Aditya's solution cleverly leverages countDistinct result of runningValue function to identify row numbers within a tablix (row) group. If you have tablix rows with missing value in the first cell, runningValue will not increment countDistinct result and it will return the previous row's number (and, therefore, will affect the formatting of that cell). To account for that, you will have to add an additional term to offset the countDistinct value. My take was to check the first running value in the row group itself (see line 3 of the snippet below):

=iif(
    (RunningValue(Fields![RowGroupField].Value, countDistinct, "FakeOrRealImmediateParentGroup")
    + iif(IsNothing(RunningValue(Fields![RowGroupField].Value, First, "GroupForRowGroupField")), 1, 0)
    ) mod 2, "White", "LightGrey")

Hope this helps.

Yes if you have no idea that how many arguments are possible at the time of function declaration then you can declare the function with no parameters and can access all variables by arguments array which are passed at the time of function calling.

<script>
    var listh = document.getElementById( 'list-home-list' );
    var hb = document.getElementsByTagName('hb');
    $("#list-home-list").click(function(){
    $(this).style.color = '#2C2E33';
    hb.style.color = 'white';
    });
</script>

File currentDirectory = new File(new File(".").getAbsolutePath());
System.out.println(currentDirectory.getCanonicalPath());
System.out.println(currentDirectory.getAbsolutePath());

Prints something like:

/path/to/current/directory
/path/to/current/directory/.

Note that File.getCanonicalPath() throws a checked IOException but it will remove things like ../../../

I navigated to:

Eclipse>Pref>Java>Installed JRE>Search...

2 of them popped up and I checked the latest one. Before I did this I also went to About>Check for Updates and updated it. I didn't have to reinstall any JRE or JDK either. I might have done it a while back, except it was with 1.6 not 1.4. Hope that helps!

Not sure if this is the most efficient answer, but it works for me:

import os
import glob
from PIL import Image
Image.MAX_IMAGE_PIXELS = None # to avoid image size warning

imgdir = "/path/to/image/folder"
# if you want file of a specific extension (.png):
filelist = [f for f in glob.glob(imgdir + "**/*.png", recursive=True)]
savedir = "/path/to/image/folder/output"

start_pos = start_x, start_y = (0, 0)
cropped_image_size = w, h = (500, 500)

for file in filelist:
    img = Image.open(file)
    width, height = img.size

    frame_num = 1
    for col_i in range(0, width, w):
        for row_i in range(0, height, h):
            crop = img.crop((col_i, row_i, col_i + w, row_i + h))
            name = os.path.basename(file)
            name = os.path.splitext(name)[0]
            save_to= os.path.join(savedir, name+"_{:03}.png")
            crop.save(save_to.format(frame_num))
            frame_num += 1

This is mostly based on DataScienceGuy answer here

I had a similar kind of situation and recently found the following command useful.

git branch -D `git branch | awk '{ if ($0 !~ /<Branch_You_Want_to_Keep>/) printf "%s", $0 }'`

If you want to keep multiple branches, then

git branch -D `git branch | awk '{ if ($0 !~ /<Branch_You_Want_to_Keep1>|<Branch_You_Want_to_Keep2>/) printf "%s", $0 }'`

hope this helps someone.

The following identifies Safari 3.0+ and distinguishes it from Chrome:

isSafari = !!navigator.userAgent.match(/Version\/[\d\.]+.*Safari/)

This line:

char b = "blah";

Is no good - your lvalue needs to be a pointer.

Your code is also in danger of a stack overflow, since your recursion check isn't bounding the decreasing value of x.

Anyway, the actual error message you are getting is because char a is an automatic variable; the moment you return it will cease to exist. You need something other than an automatic variable.

A simple modal pop up div or dialog box can be done by CSS properties and little bit of jQuery.The basic idea is simple:

So we need three divs:

    #hider
    {
        position:absolute;
        top: 0%;
        left: 0%;
        width:1600px;
        height:2000px;
        margin-top: -800px; /*set to a negative number 1/2 of your height*/
        margin-left: -500px; /*set to a negative number 1/2 of your width*/
        /*
        z- index must be lower than pop up box
       */
        z-index: 99;
       background-color:Black;
       //for transparency
       opacity:0.6;
    }

    #popup_box  
    {

    position:absolute;
        top: 50%;
        left: 50%;
        width:10em;
        height:10em;
        margin-top: -5em; /*set to a negative number 1/2 of your height*/
        margin-left: -5em; /*set to a negative number 1/2 of your width*/
        border: 1px solid #ccc;
        border:  2px solid black;
        z-index:100; 

    }

        $(document).ready(function () {
        //hide hider and popup_box
        $("#hider").hide();
        $("#popup_box").hide();

        //on click show the hider div and the message
        $("#showpopup").click(function () {
            $("#hider").fadeIn("slow");
            $('#popup_box').fadeIn("slow");
        });
        //on click hide the message and the
        $("#buttonClose").click(function () {

            $("#hider").fadeOut("slow");
            $('#popup_box').fadeOut("slow");
        });

        });

<div id="hider"></div>
<div id="popup_box">
    Message<br />
    <a id="buttonClose">Close</a>
</div>    
<div id="content">
    Page's main content.<br />
    <a id="showpopup">ClickMe</a>

You may group your library.available_until wheres area by grouping method of Codeigniter for without disable escaping where clauses.

$this->db
    ->select('*')
    ->from('library')
    ->where('library.rating >=', $form['slider'])
    ->where('library.votes >=', '1000')
    ->where('library.language !=', 'German')
    ->group_start() //this will start grouping
    ->where('library.available_until >=', date("Y-m-d H:i:s"))
    ->or_where('library.available_until =', "00-00-00 00:00:00")
    ->group_end() //this will end grouping
    ->where('library.release_year >=', $year_start)

Method to convert inputStream to String

    BufferedReader bufferedReader = null;
    StringBuilder stringBuilder = new StringBuilder();
    String line;

    try {
        bufferedReader = new BufferedReader(new InputStreamReader(

I know this is an old question, but none of the answers worked for me, because I wanted to reliably (always be able to) set the cell into edit mode when possibly executing other events like Toolbar Button clicks, menu selections, etc. that may affect the default focus after those events return. I ended up needing a timer and invoke. The following code is in a new component derived from DataGridView. This code allows me to simply make a call to myXDataGridView.CurrentRow_SelectCellFocus(myDataPropertyName); anytime I want to arbitrarily set a databound cell to edit mode (assuming the cell is Not in ReadOnly mode).

// If the DGV does not have Focus prior to a toolbar button Click, 
// then the toolbar button will have focus after its Click event handler returns.
// To reliably set focus to the DGV, we need to time it to happen After event handler procedure returns.

private string m_SelectCellFocus_DataPropertyName = "";
private System.Timers.Timer timer_CellFocus = null;

public void CurrentRow_SelectCellFocus(string sDataPropertyName)
{
  // This procedure is called by a Toolbar Button's Click Event to select and set focus to a Cell in the DGV's Current Row.
  m_SelectCellFocus_DataPropertyName = sDataPropertyName;
  timer_CellFocus = new System.Timers.Timer(10);
  timer_CellFocus.Elapsed += TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Start();
}


void TimerElapsed_CurrentRowSelectCellFocus(object sender, System.Timers.ElapsedEventArgs e)
{
  timer_CellFocus.Stop();
  timer_CellFocus.Elapsed -= TimerElapsed_CurrentRowSelectCellFocus;
  timer_CellFocus.Dispose();
  // We have to Invoke the method to avoid raising a threading error
  this.Invoke((MethodInvoker)delegate
  {
    Select_Cell(m_SelectCellFocus_DataPropertyName);
  });
}


private void Select_Cell(string sDataPropertyName)
{
  /// When the Edit Mode is Enabled, set the initial cell to the Description
  foreach (DataGridViewCell dgvc in this.SelectedCells) 
  {
    // Clear previously selected cells
    dgvc.Selected = false; 
  }
  foreach (DataGridViewCell dgvc in this.CurrentRow.Cells)
  {
    // Select the Cell by its DataPropertyName
    if (dgvc.OwningColumn.DataPropertyName == sDataPropertyName)
    {
      this.CurrentCell = dgvc;
      dgvc.Selected = true;
      this.Focus();
      return;
    }
  }
}

Generally git pull is enough, but I'm not sure what layout you have chosen (or has github chosen for you).

Templates are all about the compiler generating code at compile-time. Virtual functions are all about the run-time system figuring out which function to call at run-time.

Once the run-time system figured out it would need to call a templatized virtual function, compilation is all done and the compiler cannot generate the appropriate instance anymore. Therefore you cannot have virtual member function templates.

However, there are a few powerful and interesting techniques stemming from combining polymorphism and templates, notably so-called type erasure.

Thanks it working

here i am done with this by qty field is zero means it shown that cells are in red color

        int count = 0;

        foreach (DataGridViewRow row in ItemDg.Rows)
        {
            int qtyEntered = Convert.ToInt16(row.Cells[1].Value);
            if (qtyEntered <= 0)
            {
                ItemDg[0, count].Style.BackColor = Color.Red;//to color the row
                ItemDg[1, count].Style.BackColor = Color.Red;

                ItemDg[0, count].ReadOnly = true;//qty should not be enter for 0 inventory                       
            }
            ItemDg[0, count].Value = "0";//assign a default value to quantity enter
            count++;
        }

    }

Give them a trivial pom with these jars listed as dependencies and instructions to run:

mvn dependency:go-offline

This will pull the dependencies to the local repo.

A more direct solution is dependency:get, but it's a lot of arguments to type:

mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version

Here's another approach using json and rouge:

require 'json'
require 'rouge'

formatter = Rouge::Formatters::Terminal256.new
json_lexer = Rouge::Lexers::JSON.new

puts formatter.format(json_lexer.lex(JSON.pretty_generate(JSON.parse(response))))

(parses response from e.g. RestClient)

Very little Javascript is necessary:

window.onload = function() {
    document.body.className += " loaded";
}

Now the CSS:

.fadein {
    opacity: 0;
    -moz-transition: opacity 1.5s;
    -webkit-transition: opacity 1.5s;
    -o-transition: opacity 1.5s;
    transition: opacity 1.5s;
}

body.loaded .fadein {
    opacity: 1;
}

I know the question said "without Javascript", but I think it's worth pointing out that there is an easy solution involving one line of Javascript.

It could even be inline Javascript, something like that:

<body onload="document.body.className += ' loaded';" class="fadein">

That's all the JavaScript that's needed.

.row {
    margin-right: 15px;
}

throw this in your CSS

I had this error as well. In my case it was because there was another virtual host that was pointing to the same root directory.

Here's the simplest way to create/update while also calling the middleware and validators.

Contact.findOne({ phone: request.phone }, (err, doc) => {
    const contact = (doc) ? doc.set(request) : new Contact(request);

    contact.save((saveErr, savedContact) => {
        if (saveErr) throw saveErr;
        console.log(savedContact);
    });
})

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

I had this problem, the solution was to look at the commit graph (using gitk) and see that I had the following:

*   commit I want to cherry-pick (x)
|\  
| * branch I want to cherry-pick to (y)
* | 
|/  
* common parent (x)

I understand now that I want to do

git cherry-pick -m 2 mycommitsha

This is because -m 1 would merge based on the common parent where as -m 2 merges based on branch y, that is the one I want to cherry-pick to.

Be careful with your routes. A "redirectTo" will remove|drop any query parameter.

const appRoutes: Routes [
 {path: "one", component: PageOneComponent},
 {path: "two", component: PageTwoComponent},
 {path: "", redirectTo: "/one", pathMatch: full},
 {path: "**", redirectTo: "/two"}
]

I called my main component with query parameters like "/main?param1=a&param2=b and assume that my query parameters arrive in the "ngOnInit()" method in the main component before the redirect forwarding takes effect.

But this is wrong. The redirect will came before, drop the query parameters away and call the ngOnInit() method in the main component without query parameters.

I changed the third line of my routes to

{path: "", component: PageOneComponent},

and now my query parameters are accessible in the main components ngOnInit and also in the PageOneComponent.

Yet another bash script (i.e. will work for most unix-based systems). Based on the answer by Pedro Rodrigues, but is slightly easier to use.

Improvements over Pedro's version:

1. Original approach did not work for me on Android 7: adb pull kept complaining about no such file or directory while adb shell could access the file. Hence I used different approach, with temporary file.
2. When launched with no arguments, my script will just list all available packages. When partial package name is provided, it will try to guess the full package name. It will complain if there are several possible expansions.
3. I don't hardcode destination path; instead APKs are saved to current working directory.

Save this to an executable file:

#!/bin/bash
# Obtain APK file for given package from the device connected over ADB

if [ -z "$1" ]; then
    echo "Available packages: "
    adb shell pm list packages | sed 's/^package://'
    echo "You must pass a package to this function!"
    echo "Ex.: android_pull_apk \"com.android.contacts\""
    exit 1
fi

fullname=$(adb shell pm list packages | sed 's/^package://' | grep $1)
if [ -z "$fullname" ]; then
    echo "Could not find package matching $1"
    exit 1
fi
if [ $(echo "$fullname" | wc -l) -ne 1 ]; then
    echo "Too many packages matched:"
    echo "$fullname"
    exit 1
fi
echo "Will fetch APK for package $fullname"

apk_path="`adb shell pm path $fullname | sed -e 's/package://g' | tr '\n' ' ' | tr -d '[:space:]'`"
apk_name="`basename ${apk_path} | tr '\n' ' ' | tr -d '[:space:]'`"

destination="${fullname}.apk"

tmp=$(mktemp --dry-run --tmpdir=/sdcard --suffix=.apk)
adb shell cp "${apk_path}" "$tmp"
adb pull "$tmp" "$destination"
adb shell rm "$tmp"

[ $? -eq 0 ] && echo -e "\nAPK saved in \"$destination\""

with Apache PDFBox it goes like this:

PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
    PDFTextStripper stripper = new PDFTextStripper();
    String text = stripper.getText(document);
    System.out.println("Text:" + text);
}
document.close();

LENGTH() returns the length of the string measured in bytes.
CHAR_LENGTH() returns the length of the string measured in characters.

This is especially relevant for Unicode, in which most characters are encoded in two bytes. Or UTF-8, where the number of bytes varies. For example:

select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1

As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC in UTF-8) even though it's only one character.

you can use this extension method and call it like this.

• groupByKey() is just to group your dataset based on a key. It will result in data shuffling when RDD is not already partitioned.
• reduceByKey() is something like grouping + aggregation. We can say reduceBykey() equvelent to dataset.group(...).reduce(...). It will shuffle less data unlike groupByKey().
• aggregateByKey() is logically same as reduceByKey() but it lets you return result in different type. In another words, it lets you have a input as type x and aggregate result as type y. For example (1,2),(1,4) as input and (1,"six") as output. It also takes zero-value that will be applied at the beginning of each key.

Note : One similarity is they all are wide operations.

case the column isn't string, use astype to convert:

df['col'] = df['col'].astype(str).str[:9]

For most of my select options, I start off with an option that simply says 'Please Select' or something similar and that option is always disabled. Then whenever you want to clear your select/option's you can do just do something like this.

Example

<select id="mySelectOption">
   <option value="" selected disabled>Please select</option>
</select>

Answer

$('#mySelectOption').val('Please Select');

How to declare the various functions?

Compile, Controller, Pre-link & Post-link

If one is to use all four function, the directive will follow this form:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.
            return {
                pre: function preLink( scope, element, attributes, controller, transcludeFn ) {
                    // Pre-link code goes here
                },
                post: function postLink( scope, element, attributes, controller, transcludeFn ) {
                    // Post-link code goes here
                }
            };
        }
    };  
});

Notice that compile returns an object containing both the pre-link and post-link functions; in Angular lingo we say the compile function returns a template function.

Compile, Controller & Post-link

If pre-link isn't necessary, the compile function can simply return the post-link function instead of a definition object, like so:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.
            return function postLink( scope, element, attributes, controller, transcludeFn ) {
                    // Post-link code goes here                 
            };
        }
    };  
});

Sometimes, one wishes to add a compile method, after the (post) link method was defined. For this, one can use:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.

            return this.link;
        },
        link: function( scope, element, attributes, controller, transcludeFn ) {
            // Post-link code goes here
        }

    };  
});

Controller & Post-link

If no compile function is needed, one can skip its declaration altogether and provide the post-link function under the link property of the directive's configuration object:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        link: function postLink( scope, element, attributes, controller, transcludeFn ) {
                // Post-link code goes here                 
        },          
    };  
});

No controller

In any of the examples above, one can simply remove the controller function if not needed. So for instance, if only post-link function is needed, one can use:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        link: function postLink( scope, element, attributes, controller, transcludeFn ) {
                // Post-link code goes here                 
        },          
    };  
});

TheNewIdiot's answer successfully explains the problem and the reason why you can't send attributes in request through a redirect. Possible solutions:

1. Using forwarding. This will enable that request attributes could be passed to the view and you can use them in form of ServletRequest#getAttribute or by using Expression Language and JSTL. Short example (reusing TheNewIdiot's answer] code).

   Controller (your servlet)

   request.setAttribute("message", "Hello world");
   RequestDispatcher dispatcher = servletContext().getRequestDispatcher(url);
   dispatcher.forward(request, response);
   

   View (your JSP)

   Using scriptlets:

   <%
       out.println(request.getAttribute("message"));
   %>
   

   This is just for information purposes. Scriptlets usage must be avoided: How to avoid Java code in JSP files?. Below there is the example using EL and JSTL.

   <c:out value="${message}" />
   

2. If you can't use forwarding (because you don't like it or you don't feel it that way or because you must use a redirect) then an option would be saving a message as a session attribute, then redirect to your view, recover the session attribute in your view and remove it from session. Remember to always have your user session with only relevant data. Code example

   Controller

   //if request is not from HttpServletRequest, you should do a typecast before
   HttpSession session = request.getSession(false);
   //save message in session
   session.setAttribute("helloWorld", "Hello world");
   response.sendRedirect("/content/test.jsp");
   

   View

   Again, showing this using scriptlets and then EL + JSTL:

   <%
       out.println(session.getAttribute("message"));
       session.removeAttribute("message");
   %>
   
   <c:out value="${sessionScope.message}" />
   <c:remove var="message" scope="session" />
   

You could also use the <figure> element to link a heading to your list like this:

<figure>
    <figcaption>My favorite fruits</figcaption>    
       <ul>
          <li>Banana</li>
          <li>Orange</li>
          <li>Chocolate</li>
       </ul>
</figure>

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

Since you asked about ready-made Api's ... well Apache's commons. collections library has a CollectionUtils class that provides easy-to-use methods for Collection manipulation/checking, such as intersection, difference, and union.

executeQuery() returns a ResultSet. I'm not as familiar with Java/MySQL, but to create indexes you probably want a executeUpdate().

The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding

The part where we encode from Unicode/UTF-8 is

function utf8_to_b64( str ) {
   return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
   return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

This is one of the most used methods nowadays.

in addition to @emil-vikström's answer, checking for variable!=null would be true for variable!==null as well as for variable!==undefined (or typeof(variable)!="undefined").

I don't have an answer, but I do have an alternative.

If you use Fiddler2 to monitor traffic AND enable HTTPS Decryption, your development environment will not complain. This will not work on WinRT devices, such as Microsoft Surface, because you cannot install standard apps on them. But your development Win8 computer will be fine.

To enable HTTPS encryption in Fiddler2, go to Tools > Fiddler Options > HTTPS (Tab) > Check "Decrypt HTTPS Traffic".

I'm going to keep my eye on this thread hoping for someone to have an elegant solution.

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

You can use the same shortcut, which is used to add/remove (parts of) components ({isVisible && <SomeComponent />}).

class MyComponent extends React.Component {
  render() {
    return (
      <div someAttribute={someCondition && someValue} />
    );
  }
}

You could use a recursive scalar function:-

set nocount on

create table location (
    id int,
    name varchar(50),
    parent int
)
insert into location values
    (1,'france',null),
    (2,'paris',1),
    (3,'belleville',2),
    (4,'lyon',1),
    (5,'vaise',4),
    (6,'united kingdom',null),
    (7,'england',6),
    (8,'manchester',7),
    (9,'fallowfield',8),
    (10,'withington',8)
go
create function dbo.breadcrumb(@child int)
returns varchar(1024)
as begin
    declare @returnValue varchar(1024)=''
    declare @parent int
    select @returnValue+=' > '+name,@parent=parent
    from location
    where id=@child
    if @parent is not null
        set @returnValue=dbo.breadcrumb(@parent)+@returnValue
    return @returnValue
end
go

declare @location int=1
while @location<=10 begin
    print dbo.breadcrumb(@location)+' >'
    set @location+=1
end

produces:-

 > france >
 > france > paris >
 > france > paris > belleville >
 > france > lyon >
 > france > lyon > vaise >
 > united kingdom >
 > united kingdom > england >
 > united kingdom > england > manchester >
 > united kingdom > england > manchester > fallowfield >
 > united kingdom > england > manchester > withington >

Sure you can query your Database with SHOW TABLES and then loop through all the records but that is extra code lines and work.

PHP has a built in function to list all tables into an array for you :

mysql_list_tables - you can find more information about it at The PHP API page

Image.onload() will often work.

To use it, you'll need to be sure to bind the event handler before you set the src attribute.

The algorithm has been designed to support arbitrary input length. I.e you can compute hashes of big files like ISO of a DVD...

If there is a limitation for the input it could come from the environment where the hash function is used. Let's say you want to compute a file and the environment has a MAX_FILE limit.

But the output string will be always the same: 32 hex chars (128 bits)!

I think that where...like/=...case...then... can work with Booleans. I am using T-SQL.

Scenario: Let's say you want to get Person-30's hobbies if bool is false, and Person-42's hobbies if bool is true. (According to some, hobby-lookups comprise over 90% of business computation cycles, so pay close attn.).

CREATE PROCEDURE sp_Case
@bool   bit
AS
SELECT Person.Hobbies
FROM Person
WHERE Person.ID = 
    case @bool 
        when 0 
            then 30
        when 1
            then 42
    end;

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

In case you are coming into this right now, I've just been through it today and can summarize where this stands. If you did not try this yet, some details here might help.

I think @Omid Ariyan's approach is the best way. Add the pre-commit and post-checkout scripts. DON'T forget to name them exactly the way Omid does and DON'T forget to make them executable. If you forget either of those, they have no effect and you run "git commit" over and over wondering why nothing happens :) Also, if you cut and paste out of the web browser, be careful that the quotation marks and ticks are not altered.

If you run the pre-commit script once (by running a git commit), then the file .permissions will be created. You can add it to the repository and I think it is unnecessary to add it over and over at the end of the pre-commit script. But it does not hurt, I think (hope).

There are a few little issues about the directory name and the existence of spaces in the file names in Omid's scripts. The spaces were a problem here and I had some trouble with the IFS fix. For the record, this pre-commit script did work correctly for me:

#!/bin/bash  

SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions

# Clear the permissions database file
> $DATABASE

echo -n "Backing-up file permissions..."

IFSold=$IFS
IFS=$'\n'
for FILE  in `git ls-files`
do
   # Save the permissions of all the files in the index
   echo $FILE";"`stat -c "%a;%U;%G" $FILE` >> $DATABASE
done
IFS=${IFSold}
# Add the permissions database file to the index
git add $DATABASE

echo "OK"

Now, what do we get out of this?

The .permissions file is in the top level of the git repo. It has one line per file, here is the top of my example:

$ cat .permissions
.gitignore;660;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.doc;664;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.pdf;664;pauljohn;pauljohn

As you can see, we have

filepath;perms;owner;group

In the comments about this approach, one of the posters complains that it only works with same username, and that is technically true, but it is very easy to fix it. Note the post-checkout script has 2 action pieces,

# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE

So I am only keeping the first one, that's all I need. My user name on the Web server is indeed different, but more importantly you can't run chown unless you are root. Can run "chgrp", however. It is plain enough how to put that to use.

In the first answer in this post, the one that is most widely accepted, the suggestion is so use git-cache-meta, a script that is doing the same work that the pre/post hook scripts here are doing (parsing output from git ls-files). These scripts are easier for me to understand, the git-cache-meta code is rather more elaborate. It is possible to keep git-cache-meta in the path and write pre-commit and post-checkout scripts that would use it.

Spaces in file names are a problem with both of Omid's scripts. In the post-checkout script, you'll know you have the spaces in file names if you see errors like this

$ git checkout -- upload.sh
Restoring file permissions...chmod: cannot access  '04.StartingValuesInLISREL/Open': No such file or directory
chmod: cannot access 'Notebook.onetoc2': No such file or directory
chown: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chown: cannot access 'Notebook.onetoc2': No such file or directory

I'm checking on solutions for that. Here's something that seems to work, but I've only tested in one case

#!/bin/bash

SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions

echo -n "Restoring file permissions..."
IFSold=${IFS}
IFS=$
while read -r LINE || [[ -n "$LINE" ]];
do
   FILE=`echo $LINE | cut -d ";" -f 1`
   PERMISSIONS=`echo $LINE | cut -d ";" -f 2`
   USER=`echo $LINE | cut -d ";" -f 3`
   GROUP=`echo $LINE | cut -d ";" -f 4`

   # Set the file permissions
   chmod $PERMISSIONS $FILE
   # Set the file owner and groups
   chown $USER:$GROUP $FILE
done < $DATABASE
IFS=${IFSold}
echo "OK"

exit 0

Since the permissions information is one line at a time, I set IFS to $, so only line breaks are seen as new things.

I read that it is VERY IMPORTANT to set the IFS environment variable back the way it was! You can see why a shell session might go badly if you leave $ as the only separator.

Just for completeness: you may also use array_walk:

array_walk($yourArray, function(&$value)
{
  $value = strtolower($value);
});

From PHP docs:

If callback needs to be working with the actual values of the array, specify the first parameter of callback as a reference. Then, any changes made to those elements will be made in the original array itself.

Or directly via foreach loop using references:

foreach($yourArray as &$value)
  $value = strtolower($value);

Note that these two methods change the array "in place", whereas array_map creates and returns a copy of the array, which may not be desirable in case of very large arrays.

Why are you trying to roll your own solution. Spring-boot already supports that.

If you don't already have one, add an application.properties file to src\main\resources. In that properties file, add 2 properties:

server.contextPath=/mainstay
server.port=12378

UPDATE (Spring Boot 2.0)

As of Spring Boot 2.0 (due to the support of both Spring MVC and Spring WebFlux) the contextPath has been changed to the following:

server.servlet.contextPath=/mainstay

You can then remove your configuration for the custom servlet container. If you need to do some post processing on the container you can add a EmbeddedServletContainerCustomizer implementation to your configuration (for instance to add the error pages).

Basically the properties inside the application.properties serve as a default you can always override them by using another application.properties next to the artifact you deliver or by adding JVM parameters (-Dserver.port=6666).

See also The Reference Guide especially the properties section.

The class ServerProperties implements the EmbeddedServletContainerCustomizer. The default for contextPath is "". In your code sample you are setting the contextPath directly on the TomcatEmbeddedServletContainerFactory. Next the ServerProperties instance will process this instance and reset it from your path to "". (This line does a null check but as the default is "" it always fail and set the context to "" and thus overriding yours).
