Because NULL means 'unknown value' and two unknown values cannot be equal.

So, if to our logic NULL N°1 is equal to NULL N°2, then we have to tell that somehow:

SELECT 1
WHERE ISNULL(nullParam1, -1) = ISNULL(nullParam2, -1)

where known value -1 N°1 is equal to -1 N°2

If you use MAMP, make sure it's started. :)

I just ran into this problem, and after starting MAMP the error went away. Not my finest moment.

Oneliner in Swift 4.2

let size = text.size(withAttributes:[.font: UIFont.systemFont(ofSize:18.0)])

This will be the simplest solution. I tried most of the solutions in the internet but only this helped me.

@print{
    @page :footer {color: #fff }
    @page :header {color: #fff}
}

If the functions are exposed - non-member, public or protected - then the caller should know about them, and the default values must be in the header.

If the functions are private and out-of-line, then it does make sense to put the defaults in the implementation file because that allows changes that don't trigger client recompilation (a sometimes serious issue for low-level libraries shared in enterprise scale development). That said, it is definitely potentially confusing, and there is documentation value in presenting the API in a more intuitive way in the header, so pick your compromise - though consistency's the main thing when there's no compelling reason either way.

try this if you want your radio button to be checked based on value of some variable e.g. "genderStr" then you can use following code snippet

    if(genderStr.equals("Male"))
       genderRG.check(R.id.maleRB);
    else 
       genderRG.check(R.id.femaleRB);

A gcc spec file can do the job, however all users on the machine will be affected.

See here

Give this a go:

var distinct_list 

  = data.DATA.map(function (d) {return d[x];}).filter((v, i, a) => a.indexOf(v) === i)

Create a DataView. You cannot sort a DataTable directly, but you can create a DataView from the DataTable and sort that.

Creating: http://msdn.microsoft.com/en-us/library/hy5b8exc.aspx

Sorting: http://msdn.microsoft.com/en-us/library/13wb36xf.aspx

The following code example creates a view that shows all the products where the number of units in stock is less than or equal to the reorder level, sorted first by supplier ID and then by product name.

DataView prodView = new DataView(prodDS.Tables["Products"], "UnitsInStock <= ReorderLevel", "SupplierID, ProductName", DataViewRowState.CurrentRows);

composer dump-autoload 

this will fix it

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

You have to write a specific media query for this, from your question, below 768px, the navbar will collapse, so apply it above 768px and below 1000px, just like that:

@media (min-width: 768px) and (max-width: 1000px) {
   .collapse {
       display: none !important;
   }
}

This will hide the navbar collapse until the default occurrence of the bootstrap unit. As the collapse class flips the inner assets inside navbar collapse will be automatically hidden, like wise you have to set your css as you desired design.

I wouldn't try to temporarily enable a deprecated feature. According to the MDN documentation for showModalDialog, there's already a polyfill available on Github.

I just used that to add windows.showModalDialog to a legacy enterprise application as a userscript, but you can obviously also add it in the head of the HTML if you have access to the source.

I like the answers from The Aelfinn and aheld. I can improve them only by shortening a bit more, removing superfluous pieces, using a real data source, making it 2.x & 3.x-compatible, and maintaining the high-level of memory-efficiency seen elsewhere:

import csv
import requests

CSV_URL = 'http://web.cs.wpi.edu/~cs1004/a16/Resources/SacramentoRealEstateTransactions.csv'

with requests.get(CSV_URL, stream=True) as r:
    lines = (line.decode('utf-8') for line in r.iter_lines())
    for row in csv.reader(lines):
        print(row)

Too bad 3.x is less flexible CSV-wise because the iterator must emit Unicode strings (while requests does bytes) while the 2.x-only version—for row in csv.reader(r.iter_lines()):—is more Pythonic (shorter and easier-to-read). Anyhow, note the 2.x/3.x solution above won't handle the situation described by the OP where a NEWLINE is found unquoted in the data read.

For the part of the OP's question regarding downloading (vs. processing) the actual CSV file, here's another script that does that, 2.x & 3.x-compatible, minimal, readable, and memory-efficient:

import os
import requests

CSV_URL = 'http://samplecsvs.s3.amazonaws.com/Sacramentorealestatetransactions.csv'

with open(os.path.split(CSV_URL)[1], 'wb') as f, \
        requests.get(CSV_URL, stream=True) as r:
    for line in r.iter_lines():
        f.write(line+'\n'.encode())

Variables are not defined, but declared.

This is possible duplicate of declare variables in a pl/sql block

As others have said, there is now an option for Ctrl+Shf+Vfor paste in Windows 10 Insider build #17643.

Unfortunately this isn't in my muscle memory and as a user of TTY terminals I'd like to use Shf+Ins as I do on all the Linux boxes I connect to.

This is possible on Windows 10 if you install ConEmu which wraps the terminal in a new GUI and allows Shf+Ins for paste. It also allows you to tweak the behaviour in the Properties.

The Console looks like this:

Copy options:

Paste options:

Shf+Ins works out of the box. I can't remember if you need to configure bash as one of the shells it uses but if you do, here is the task properties to add it:

Also allows tabbed Consoles (including different types, cmd.exe, powershell etc). I've been using this since early Windows 7 and in those days it made the command line on Windows usable!

Fastest and easiest way is to use an iframe. Put a frame at the bottom of your page.

<iframe name="frame"></iframe>

And in your form do this.

<form target="frame">
</form>

and to make the frame invisible in your css.

iframe{
  display: none;
}

}); 

I think my answer to my own question here is the simplest solution to what you are trying to do:

1. Select the cell where the first line of text from the file should be.

2. Use the Data/Get External Data/From File dialog to select the text file to import.

3. Format the imported text as required.

4. In the Import Data dialog that opens, click on Properties...

5. Uncheck the Prompt for file name on refresh box.

6. Whenever the external file changes, click the Data/Get External Data/Refresh All button.

Note: in your case, you should probably want to skip step #5.

If you're using Sublime, you can easily generate hundreds or thousands of lines using Text Pastry in conjunction with multiple line selection and Emmet.

So in my case I set the document type to html, then typed div*249, hit tab and Emmet creates 249 empty divs. Then using multiple selection I typed col_id_ in each one and triggered Text Pastry to insert an incremental id number. Then with multiple selection again you can delete the div markup and replace it with the MySQL syntax.

While the other answers have not worked for me in all situations, the best solution I could find (working with POST as well), taken from here:

curl -vs 'https://some-site.com' 1> /dev/null

FileInfo.Length will do the trick (per MSDN it "[g]ets the size, in bytes, of the current file.") There is a nice page on MSDN on common I/O tasks.

SELECT * FROM testcases1 t WHERE NOT EXISTS ( SELECT 1
FROM executions1 i WHERE t.tc_id = i.tc_id and t.pro_id=i.pro_id and pro_id=7 and version_id=5 ) and pro_id=7 ;

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.

To Convert Generic list into DataTable

using Newtonsoft.Json;

public DataTable GenericToDataTable(IList<T> list)
{
    var json = JsonConvert.SerializeObject(list);
    DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));
    return dt;
}

in your ajax request, adding:

dataType: "jsonp",

after line :

type: 'GET',

should solve this problem ..

hope this help you

solved by deleting the target folder manually.

This will work nicely with in-line arrays. Plus, I think things are tidier and more reusable when wrapped up in a function.

function array_rand_value($a) {
    return $a[array_rand($a)];
}

Usage:

array_rand_value(array("a", "b", "c", "d"));

On PHP < 7.1.0, array_rand() uses rand(), so you wouldn't want to this function for anything related to security or cryptography. On PHP 7.1.0+, use this function without concern since rand() has been aliased to mt_rand().

For img tags if you define one side then other side is resized to keep aspect ratio and by default images expand to their original size.

Using this fact if you wrap each img tag into div tag and set its width to 100% of parent div then height will be according to aspect ratio as you wanted.

http://jsfiddle.net/0o5tpbxg/

* {
    margin: 0;
    padding: 0;
}
.slider {
    display: flex;
}
.slider .slide img {
    width: 100%;
}

The answers are correct but don't mention how to sync code between the public repo and the fork.

Here is the full workflow (we've done this before open sourcing React Native):

First, duplicate the repo as others said (details here):

Create a new repo (let's call it private-repo) via the Github UI. Then:

git clone --bare https://github.com/exampleuser/public-repo.git
cd public-repo.git
git push --mirror https://github.com/yourname/private-repo.git
cd ..
rm -rf public-repo.git

Clone the private repo so you can work on it:

git clone https://github.com/yourname/private-repo.git
cd private-repo
make some changes
git commit
git push origin master

To pull new hotness from the public repo:

cd private-repo
git remote add public https://github.com/exampleuser/public-repo.git
git pull public master # Creates a merge commit
git push origin master

Awesome, your private repo now has the latest code from the public repo plus your changes.

Finally, to create a pull request private repo -> public repo:

Use the GitHub UI to create a fork of the public repo (the small "Fork" button at the top right of the public repo page). Then:

git clone https://github.com/yourname/the-fork.git
cd the-fork
git remote add private_repo_yourname https://github.com/yourname/private-repo.git
git checkout -b pull_request_yourname
git pull private_repo_yourname master
git push origin pull_request_yourname

Now you can create a pull request via the Github UI for public-repo, as described here.

Once project owners review your pull request, they can merge it.

Of course the whole process can be repeated (just leave out the steps where you add remotes).

Use Fail module.

1. Use ignore_errors with every task that you need to ignore in case of errors.
2. Set a flag (say, result = false) whenever there is a failure in any task execution
3. At the end of the playbook, check if flag is set, and depending on that, fail the execution

- fail: msg="The execution has failed because of errors."
  when: flag == "failed"

Update:

Use register to store the result of a task like you have shown in your example. Then, use a task like this:

- name: Set flag
  set_fact: flag = failed
  when: "'FAILED' in command_result.stderr"

Here is another concrete example.It is for a shared library. The shared library's main function is to communicate with a smart card reader. But it can also receive 'configuration information' at runtime over udp. The udp is handled by a thread which MUST be started at init time.

__attribute__((constructor))  static void startUdpReceiveThread (void) {
    pthread_create( &tid_udpthread, NULL, __feigh_udp_receive_loop, NULL );
    return;

  }

The library was written in c.

You can simply use the zoom property:

#myContainer{
    zoom: 0.5;
    -moz-transform: scale(0.5);
}

Where myContainer contains all the elements you're editing. This is supported in all major browsers.

Recently I found this:

ArrayList<T> yourList = Collections.list(Collections.enumeration(yourSet<T>));

I've faced this same problem recently and came across to this thread but my problem was with React App. Below changes in the node start command solved my issues.

Syntax

node --max-old-space-size=<size> path-to/fileName.js

Example

node --max-old-space-size=16000 scripts/build.js

Why size is 16000 in max-old-space-size?

Basically, it varies depends on the allocated memory to that thread and your node settings.

How to verify and give right size?

This is basically stay in our engine v8. below code helps you to understand the Heap Size of your local node v8 engine.

const v8 = require('v8');
const totalHeapSize = v8.getHeapStatistics().total_available_size;
const totalHeapSizeGb = (totalHeapSize / 1024 / 1024 / 1024).toFixed(2);
console.log('totalHeapSizeGb: ', totalHeapSizeGb);

If you're ever dynamically generating page content or loading content through AJAX, the following example is really the way you should go:

1. It prevents double binding in the case where the script is loaded more than once, such as in an AJAX request.
2. The bind lives on the body of the document, so regardless of what elements are added, moved, removed and re-added, all descendants of body matching the selector specified will retain proper binding.

The Code:

// Define the element we wish to bind to.
var bind_to = ':input';

// Prevent double-binding.
$(document.body).off('change', bind_to);

// Bind the event to all body descendants matching the "bind_to" selector.
$(document.body).on('change keyup', bind_to, function(event) {
    alert('something happened!');
});

Please notice! I'm making use of $.on() and $.off() rather than other methods for several reasons:

1. $.live() and $.die() are deprecated and have been omitted from more recent versions of jQuery.
2. I'd either need to define a separate function (therefore cluttering up the global scope,) and pass the function to both $.change() and $.keyup() separately, or pass the same function declaration to each function called; Duplicating logic... Which is absolutely unacceptable.
3. If elements are ever added to the DOM, $.bind() does not dynamically bind to elements as they are created. Therefore if you bind to :input and then add an input to the DOM, that bind method is not attached to the new input. You'd then need to explicitly un-bind and then re-bind to all elements in the DOM (otherwise you'll end up with binds being duplicated). This process would need to be repeated each time an input was added to the DOM.

SELECT CONVERT(CHAR(10),GETDATE(),103) + ' ' + RIGHT(CONVERT(CHAR(26),GETDATE(),109),14)

Or you can apply HighlightBrushKey directly to the ListBox. Setter Property="Background" Value="Transparent" did NOT work. But I did have to set the Foreground to Black.

<ListBox  ... >
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True" >
                    <Setter Property="FontWeight" Value="Bold" />
                    <Setter Property="Background" Value="Transparent" />
                    <Setter Property="Foreground" Value="Black" />
                </Trigger>
            </Style.Triggers>
            <Style.Resources>
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
            </Style.Resources>
        </Style>                
    </ListBox.ItemContainerStyle>
</ListBox>

A mix of native Javascript and jQuery:

var gFireEvent = function (oElem,sEvent) 
{
 try {
 if( typeof sEvent == 'string' && o.isDOM( oElem ))
 {
  var b = !!(document.createEvent),
     evt = b?document.createEvent("HTMLEvents"):document.createEventObject();
  if( b )    
  {  evt.initEvent(sEvent, true, true ); 
    return !oElem.dispatchEvent(evt);
  }
  return oElem.fireEvent('on'+sEvent,evt);
 }
 } catch(e) {}
 return false;
};


// Next you can do is (bIsMob etc you have to determine yourself):

   if( <<< bIsMob || bIsTab || bisTouch >>> )
   {
     $(document).on('mousedown', function(e)
     {
       gFireEvent(e.target,'mouseover' );
     }).on('mouseup', function(e)
     {
       gFireEvent(e.target,'mouseout' );
     });
   }

It must be synchronized, using an object lock, stateless, or immutable.

for more exactly positioning:

      background-position: bottom 5px right 7px;

: is the delimiter of the slice syntax to 'slice out' sub-parts in sequences , [start:end]

[1:5] is equivalent to "from 1 to 5" (5 not included)
[1:] is equivalent to "1 to end"
[len(a):] is equivalent to "from length of a to end"

Watch https://youtu.be/tKTZoB2Vjuk?t=41m40s at around 40:00 he starts explaining that.

Works with tuples and strings, too.

If you are looking for ReactNative's componentDidMount equivalent, Flutter has it. It's not that simple but it's working just the same way. In Flutter, Widgets do not handle their events directly. Instead they use their State object to do that.

class MyWidget extends StatefulWidget{

  @override
  State<StatefulWidget> createState() => MyState(this);

  Widget build(BuildContext context){...} //build layout here

  void onLoad(BuildContext context){...} //callback when layout build done
}

class MyState extends State<MyWidget>{

  MyWidget widget;

  MyState(this.widget);

  @override
  Widget build(BuildContext context) => widget.build(context);

  @override
  void initState() => widget.onLoad(context);
}

State.initState immediately will be called once upon screen has finishes rendering the layout. And will never again be called even on hot reload if you're in debug mode, until explicitly reaches time to do so.

CORS is Cross Origin Resource Sharing, you get this error if you are trying to access from one domain to another domain.

Try using JSONP. In your case, JSONP should work fine because it only uses the GET method.

Try something like this:

var url = "https://api.getevents.co/event?&lat=41.904196&lng=12.465974";
$http({
    method: 'JSONP',
    url: url
}).
success(function(status) {
    //your code when success
}).
error(function(status) {
    //your code when fails
});

In one of my projects I run tests against Python 2 and 3. For that I wrote a small script which starts a local server independently:

$ python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')
Serving HTTP on 0.0.0.0 port 8000 ...

As an alias:

$ alias serve="python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')"
$ serve
Serving HTTP on 0.0.0.0 port 8000 ...

Please note that I control my Python version via conda environments, because of that I can use python instead of python3 for using Python 3.

probably it is better to use NSString and load html document as follows:

Objective-C

NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL: [[NSBundle mainBundle] bundleURL]];

Swift

let htmlFile = NSBundle.mainBundle().pathForResource("fileName", ofType: "html")
let html = try? String(contentsOfFile: htmlFile!, encoding: NSUTF8StringEncoding)
webView.loadHTMLString(html!, baseURL: nil) 

Swift 3 has few changes:

let htmlFile = Bundle.main.path(forResource: "intro", ofType: "html")
let html = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
webView.loadHTMLString(html!, baseURL: nil)

Did you try?

Also check that the resource was found by pathForResource:ofType:inDirectory call.

Also you can add #include<vector> in the header. When two of the above solutions don't work.

For UIButton you should use:-

[btn setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];

You can use expand.grid( ) function.

x <-c(1,2,3)
y <-c(100,200,300)
expand.grid(cond=x,rating=y)

I recently had to figure this out for myself and ended up on a solution inspired by @Zahymaka 's answer, but solving the 2x looping of the array.

What you can do is create an array with all your keys, in the order they exist, and then loop through that.

        $keys=array_keys($items);
        foreach($keys as $index=>$key){
                    echo "position: $index".PHP_EOL."item: ".PHP_EOL;
                    var_dump($items[$key]);

Here is another solution I have just build with css grids based on the answers in here:

https://codesandbox.io/s/sweet-resonance-m733i

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

Not sure I completely understand the question but:

$(":button.brown").click(function() {
  $(":button.brown.selected").removeClass("selected");
  $(this).addClass("selected");
});

seems to be along the lines of what you want.

I would certainly recommend using classes instead of directly setting CSS, which is problematic for several reasons (eg removing styles is non-trivial, removing classes is easy) but if you do want to go that way:

$("...").css("background", "brown");

But when you want to reverse that change, what do you set it to?

To compile separately without linking you need to add -c option:

I have edited the given above example...

public class YourActivity extends implements OnMarkerClickListener
{
    ......

    private void setMarker()
    {
        .......
        googleMap.setOnMarkerClickListener(this);

        myMarker = googleMap.addMarker(new MarkerOptions()
                    .position(latLng)
                    .title("My Spot")
                    .snippet("This is my spot!")
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
        ......
    }

    @Override
    public boolean onMarkerClick(Marker marker) {

       Toast.makeText(this,marker.getTitle(),Toast.LENGTH_LONG).show();
    }
}

I tried this and it totally works. The code is:

stage.getIcons().add(
   new Image(
      <yourclassname>.class.getResourceAsStream( "icon.png" ))); 

icon.png is under the same folder as the source files.

To use in Eloquent. Add on top of your model

protected $table = 'table_name as alias'

//table_name should be exact as in your database

..then use in your query like

ModelName::query()->select(alias.id, alias.name)

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

On Windows 10, curl 7.28.1 within powershell, I found the following to work for me:

$filePath = "c:\temp\dir with spaces\myfile.wav"
$curlPath = ("myfilename=@" + $filePath)
curl -v -F $curlPath URL

You might also encounter an error message. "Operand type clash: date is incompatible with int.

Use single quotes around the dates. E.g.: $this->db->where("$accommodation BETWEEN '$minvalue' AND '$maxvalue'");

You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

It depends on the size of your database.

SQL is based on the SET theory: there is no order inherently used when querying a table.

So if you were to run the first query, it would first order by product price and then product name, IF there were any duplicates in the price category, say $20 for example, it would then order those duplicates by their names, therefore always maintaining that when you run your query it will always return the same set of result in the same order.

If you were to run the second query, it would only order by the name, so if there were two products with the same name (for some odd reason) then they wouldn't have a guaranteed order after you run the query.

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

math.fabs() converts its argument to float if it can (if it can't, it throws an exception). It then takes the absolute value, and returns the result as a float.

In addition to floats, abs() also works with integers and complex numbers. Its return type depends on the type of its argument.

In [7]: type(abs(-2))
Out[7]: int

In [8]: type(abs(-2.0))
Out[8]: float

In [9]: type(abs(3+4j))
Out[9]: float

In [10]: type(math.fabs(-2))
Out[10]: float

In [11]: type(math.fabs(-2.0))
Out[11]: float

In [12]: type(math.fabs(3+4j))

In the Notifications case, the NotificationCompat.Builder uses Builder Pattern

like,

mBuilder = new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_stat_notification)
                    .setContentTitle(getString(R.string.notification))
                    .setContentText(getString(R.string.ping))
                    .setDefaults(Notification.DEFAULT_ALL);

You will have to download file from here https://commons.apache.org/proper/commons-io/download_io.cgi and select https://prnt.sc/tk5ewt

I had the same problem with exactly the same error message. In the end the error was, that I still called the maps v2 javascript. I had to replace:

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=####################" type="text/javascript"></script>

with

<script src="http://maps.googleapis.com/maps/api/js?key=####################&sensor=false" type="text/javascript"></script>

after this, it worked fine. took me a while ;-)

Go to NugetPackage manager of you project-> Browse and search for mahApps.Metro -> install package into you project. You will see Reference added: MahApps.Metro. Then in you XAML code add:

"xmlns:mah="http://metro.mahapps.com/winfx/xaml/controls"

Where you want to use your object add:

<mah:NumericUpDown x:Name="NumericUpDown" ... /> 

Enjoy the full extensibility of the object (Bindings, triggers and so on...).

If you only need the date and not the time use:

select*from table where exec_datetime
between subdate(curdate(), 30)and curdate();

Since curdate() omits the time component, it's potentially faster than now() and more "semantically correct" in cases where you're only interested in the date.

Also, subdate()'s 2-arity overload is potentially faster than using interval. interval is meant to be for cases when you need a non-day component.

I have finalized the code for phone numbers +9 (987) 124124.

Unicode characters occupy 4 bytes.

public static String stripNonDigitsV2( CharSequence input ) {
    if (input == null)
        return null;
    if ( input.length() == 0 )
        return "";

    char[] result = new char[input.length()];
    int cursor = 0;
    CharBuffer buffer = CharBuffer.wrap( input );
    int i=0;
    while ( i< buffer.length()  ) { //buffer.hasRemaining()
        char chr = buffer.get(i);
        if (chr=='u'){
            i=i+5;
            chr=buffer.get(i);
        }

        if ( chr > 39 && chr < 58 )
            result[cursor++] = chr;
        i=i+1;
    }

    return new String( result, 0, cursor );
}

As others have said it depends on the encoding of the values in the byte array. Despite this you need to be very careful with this sort of thing or you may try to convert bytes that are not handled by the chosen encoding.

Jon Skeet has a good article about encoding and unicode in .NET. Recommended reading.

You can use your "git url" in 'https" URL format in the Jenkinsfile or wherever you want.

For me this problem arised while trying to connect to the SAP Hana database. When I got this error,

OperationalError: Lost connection to HANA server (ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))

I tried to run the code for connection(mentioned below), which created that error, again and it worked.

    import pyhdb
    connection = pyhdb.connect(host="example.com",port=30015,user="user",password="secret")
    cursor = connection.cursor()
    cursor.execute("SELECT 'Hello Python World' FROM DUMMY")
    cursor.fetchone()
    connection.close()

It was because the server refused to connect. It might require you to wait for a while and try again. Try closing the Hana Studio by logging off and then logging in again. Keep running the code for a number of times.

I found using okHttp a lot easier as I could not get any of these solutions to work: https://stackoverflow.com/a/37942387/447549

It happen if there are two more ContextLoaderListener exist in your project.

For ex: in my case 2 ContextLoaderListener was exist using

1. java configuration
2. web.xml

So, remove any one ContextLoaderListener from your project and run your application.

Either make an account on the Nuget.org website, then log in, browse to the package you want and click on the Download link on the left menu.

Or guess the URL. They have the following format:

https://www.nuget.org/api/v2/package/{packageID}/{packageVersion}

Then simply unzip the .nupkg file and extract the contents you need.

.NET 2.0 does not support LINQ - SO thread;
But you can create a 3.5 project in VS2005 - MSDN thread

Without lambda support, you'll need to do something like this:

string s = "a,b, b, c";
string[] values = s.Split(',');
for(int i = 0; i < values.Length; i++)
{
   values[i] = values[i].Trim();
}

You can try this:

Your html code like this:

<div id="container">
  <div id="left"></div>
  <div id="right"></div>
  <div id="center"></div>
</div>

and your css code like this:

#container{width:100%;}
#left{float:left;width:100px;}
#right{float:right;width:100px;}
#center{margin:0 auto;width:100px;}

so, it's output should be get like this:

[[LEFT]       [CENTER]        [RIGHT]]

you can create an array that filled with your object fields and use an index on the array and access object properties via that

propertiesName:['pr1','pr2','pr3']

this.myObject[this.propertiesName[0]]

This is the simplest solution I guess :

function diffArray(arr1, arr2) {
  return arr1
    .concat(arr2)
    .filter(item => !arr1.includes(item) || !arr2.includes(item));
}

I was trying to integrate the public IP Address into my workflow and these answers didn't help (I like to use the IDE as the IDE). But the above lead me to the solution (after about 2 hours of beating my head against a wall to get this to integrate with Visual Studio 2012 / Windows 8) here's what ended up working for me.

applicationhost.config generated by VisualStudio under C:\Users\usr\Documents\IISExpress\config

    <site name="MySite" id="1">
        <application path="/" applicationPool="Clr4IntegratedAppPool">
            <virtualDirectory path="/" physicalPath="C:\Users\usr\Documents\Visual Studio 2012\Projects\MySite" />
        </application>
        <bindings>
            <binding protocol="http" bindingInformation="*:8081:localhost" />
            <binding protocol="http" bindingInformation="*:8082:localhost" />
            <binding protocol="http" bindingInformation="*:8083:192.168.2.102" />
        </bindings>
    </site>

• Set IISExpress to run as Administrator so that it can bind to outside addresses (not local host)
• Run Visual Stuio as an Administrator so that it can start the process as an administrator allowing the binding to take place.

The net result is you can browse to 192.168.2.102 in my case and test (for instance in an Android emulator. I really hope this helps someone else as this was definitely an irritating process for me.

Apparently it is a security feature which I'd love to see disabled.

You have to put the second div on top of the first one because the both have an z-index of zero so that the order in the dom will decide which is on top. This also affects the relative positioned div because its z-index relates to elements inside the parent div.

<div class="absolute" style="top: 54px"></div>
<div class="absolute">
    <div id="relative"></div>
</div>

Css stays the same.

If you have one large dataframe and only a few update values I would use apply like this:

import pandas as pd

df = pd.DataFrame({'filename' :  ['test0.dat', 'test2.dat'], 
                                  'm': [12, 13], 'n' : [None, None]})

data = {'filename' :  'test2.dat', 'n':16}

def update_vals(row, data=data):
    if row.filename == data['filename']:
        row.n = data['n']
    return row

df.apply(update_vals, axis=1)

You can just make a System.Uri object, and use IsFile to verify it's a file, then Uri.LocalPath to extract the filename.

This is much safer, as it provides you a means to check the validity of the URI as well.

Edit in response to comment:

To get just the full filename, I'd use:

Uri uri = new Uri(hreflink);
if (uri.IsFile) {
    string filename = System.IO.Path.GetFileName(uri.LocalPath);
}

This does all of the error checking for you, and is platform-neutral. All of the special cases get handled for you quickly and easily.

If the data read from the stream is large, I would recommend using a TeeInputStream from Apache Commons IO. That way you can essentially replicate the input and pass a t'd pipe as your clone.

To generate the scaffold:

rails generate scaffold abc

To revert this scaffold:

rails destroy scaffold abc

If you have run the migration for it just rollback

rake db:rollback STEP=1

The formula

=OFFSET(Sheet1!$A$1,MOD(ROW()-1,COUNT(Sheet1!$A$1:$A$20000)),
    (ROW()-1)/COUNT(Sheet1!$A$1:$A$20000))

placed into each cell of your second workbook will retrieve the appropriate cell from the source sheet. No macros, simple copying from one sheet to another to reformat the results.

You will need to modify the ranges in the COUNT function to match the maximum number of rows in the source sheet. Adjust for column headers as required.

If you need something other than a 0 for empty cells, you may prefer to include a conditional.

A script to reformat the data may well be more efficient, but 20k rows is no longer a real limit in a modern Excel workbook.

This is the method which i used to convert the integer to string.Correct me if i did wrong.

/**
 * @param a
 * @return
 */
private String convertToString(int a) {

    int c;
    char m;
    StringBuilder ans = new StringBuilder();
    // convert the String to int
    while (a > 0) {
        c = a % 10;
        a = a / 10;
        m = (char) ('0' + c);
        ans.append(m);
    }
    return ans.reverse().toString();
}

jQuery("[name='test']") 

Although you should avoid it and if possible select by ID (e.g. #myId) as this has better performance because it invokes the native getElementById.

Declare them before the while loop.

$hn = "";
$pid = "";
$datereg = "";
$prefix = "";
$fname = "";
$lname = "";
$age = "";
$sex = "";

You are getting the notice because the variables are declared and assigned inside the loop.

a,b=[],[]
n=int(input("Provide me size of squre matrix row==column : "))
for i in range(n):
   for j in range(n):
      b.append(int(input()))
    a.append(b)
    print("Here your {} column {}".format(i+1,a))
    b=[]
for m in range(n):
    print(a[m])

works perfectly

object[] xparams = {
            new SqlParameter("@ParametterWithNummvalue", DBNull.Value),
            new SqlParameter("@In_Parameter", "Value"),
            new SqlParameter("@Out_Parameter", SqlDbType.Int) {Direction = ParameterDirection.Output}};

        YourDbContext.Database.ExecuteSqlCommand("exec StoreProcedure_Name @ParametterWithNummvalue, @In_Parameter, @Out_Parameter", xparams);
        var ReturnValue = ((SqlParameter)params[2]).Value;  

I always convert the byte data to a Base64 encoding and then insert the image.

This is also the way that Word does it, for it's XML files (not that Word is a good example on how to work with XML :P).

you can drop the Constraint which is restricting you. If the column has access to other table. suppose a view is accessing the column which you are altering then it wont let you alter the column unless you drop the view. and after making changes you can recreate the view.

i have experienced the same problem, and after reading this post i have double checked the JAVA_HOME definition in .bash_profile. It is actually:

export JAVA_HOME=$(which java)

that, exactly as Anony-Mousse is explaining, is the executable. Changing it to:

export=/Library/Java/Home

fixes the problem, tho is still interesting to understand why it's valued in that way in the profile file.

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

Let us consider we are storing the student details of 3 students. These 3 students are having different values for sno, sname and sage, but all 3 students belongs to same department CSE. So it is better to initialize "dept" variable inside a constructor so that this value can be taken by all the 3 student objects.

To understand clearly, see the below simple example:

class Student
{
    int sno,sage;
    String sname,dept;
    Student()
    {
        dept="CSE";
    }
    public static void main(String a[])
    {
        Student s1=new Student();
        s1.sno=101;
        s1.sage=33;
        s1.sname="John";

        Student s2=new Student();
        s2.sno=102;
        s2.sage=99;
        s2.sname="Peter";


        Student s3=new Student();
        s3.sno=102;
        s3.sage=99;
        s3.sname="Peter";
        System.out.println("The details of student1 are");
        System.out.println("The student no is:"+s1.sno);
        System.out.println("The student age is:"+s1.sage);
        System.out.println("The student name is:"+s1.sname);
        System.out.println("The student dept is:"+s1.dept);


        System.out.println("The details of student2 are");`enter code here`
        System.out.println("The student no is:"+s2.sno);
        System.out.println("The student age is:"+s2.sage);
        System.out.println("The student name is:"+s2.sname);
        System.out.println("The student dept is:"+s2.dept);

        System.out.println("The details of student2 are");
        System.out.println("The student no is:"+s3.sno);
        System.out.println("The student age is:"+s3.sage);
        System.out.println("The student name is:"+s3.sname);
        System.out.println("The student dept is:"+s3.dept);
    }
}

Output:

The details of student1 are
The student no is:101
The student age is:33
The student name is:John
The student dept is:CSE
The details of student2 are
The student no is:102
The student age is:99
The student name is:Peter
The student dept is:CSE
The details of student2 are
The student no is:102
The student age is:99
The student name is:Peter
The student dept is:CSE

Checking that strings are integers is separate to comparing if one is greater or lesser than another. You should always compare number with number and string with string as the algorithm for dealing with mixed types not easy to remember.

'00100' < '1' // true

as they are both strings so only the first zero of '00100' is compared to '1' and because it's charCode is lower, it evaluates as lower.

However:

'00100' < 1 // false

as the RHS is a number, the LHS is converted to number before the comparision.

A simple integer check is:

function isInt(n) {
  return /^[+-]?\d+$/.test(n);
}

It doesn't matter if n is a number or integer, it will be converted to a string before the test.

If you really care about performance, then:

var isInt = (function() {
  var re = /^[+-]?\d+$/;

  return function(n) {
    return re.test(n);
  }
}());

Noting that numbers like 1.0 will return false. If you want to count such numbers as integers too, then:

var isInt = (function() {
  var re = /^[+-]?\d+$/;
  var re2 = /\.0+$/;

  return function(n) {
    return re.test((''+ n).replace(re2,''));
  }
}());

Once that test is passed, converting to number for comparison can use a number of methods. I don't like parseInt() because it will truncate floats to make them look like ints, so all the following will be "equal":

parseInt(2.9) == parseInt('002',10) == parseInt('2wewe')

and so on.

Once numbers are tested as integers, you can use the unary + operator to convert them to numbers in the comparision:

if (isInt(a) && isInt(b)) {
  if (+a < +b) {
    // a and b are integers and a is less than b
  }
}

Other methods are:

Number(a); // liked by some because it's clear what is happening
a * 1      // Not really obvious but it works, I don't like it

Normally this error occurs when you invoke java by supplying the wrong arguments/options. In this case it should be the version option.

java -version

So to double check you can always do java -help, and see if the option exists. In this case, there is no option such as v.

It's notable to understand that if you'd like to conditionally add attributes you can also add a dynamic declaration:

<input v-bind="attrs" />

where attrs is declared as an object:

data() {
    return {
        attrs: {
            required: true,
            type: "text"
        }
    }
}

Which will result in:

<input required type="text"/>

Ideal in cases with multiple attributes.

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

Although the accepted solution is correct for iPhones, it will incorrectly declare both isiPhone and isiPad to be true for users visiting your site on their iPad from the Facebook app.

The conventional wisdom is that iOS devices have a user agent for Safari and a user agent for the UIWebView. This assumption is incorrect as iOS apps can and do customize their user agent. The main offender here is Facebook.

Compare these user agent strings from iOS devices:

# iOS Safari
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
iPhone: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

# UIWebView
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

# Facebook UIWebView
iPad: Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; ru_RU) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1;FBBV/4100.0;FBDV/iPhone3,1;FBMD/iPhone;FBSN/iPhone OS;FBSV/5.1.1;FBSS/2; tablet;FBLC/en_US]

Note that on the iPad, the Facebook UIWebView's user agent string includes 'iPhone'.

The old way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);

If you were to go with this approach for detecting iPhone and iPad, you would end up with IS_IPHONE and IS_IPAD both being true if a user comes from Facebook on an iPad. That could create some odd behavior!

The correct way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = (navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);
if (IS_IPAD) {
  IS_IPHONE = false;
}

We declare IS_IPHONE to be false on iPads to cover for the bizarre Facebook UIWebView iPad user agent. This is one example of how user agent sniffing is unreliable. The more iOS apps that customize their user agent, the more issues user agent sniffing will have. If you can avoid user agent sniffing (hint: CSS Media Queries), DO IT.

I suggest to use autotools:

//## Place generated object files (.o) into the same directory as their source files, in order to avoid collisions when non-recursive make is used.

AUTOMAKE_OPTIONS = subdir-objects

just including it in Makefile.am with the other quite simple stuff.

Here is the tutorial.

Just to add to yamen's answer, which is perfect for images but not so much for text.

If you are trying to use this to scale text, like say a Word document (which is in this case in bytes from Word Interop), you will need to make a few modifications or you will get giant bars on the side.

May not be perfect but works for me!

using (MemoryStream ms = new MemoryStream(wordBytes))
{
    float width = 3840;
    float height = 2160;
    var brush = new SolidBrush(Color.White);

    var rawImage = Image.FromStream(ms);
    float scale = Math.Min(width / rawImage.Width, height / rawImage.Height);
    var scaleWidth  = (int)(rawImage.Width  * scale);
    var scaleHeight = (int)(rawImage.Height * scale);
    var scaledBitmap = new Bitmap(scaleWidth, scaleHeight);

    Graphics graph = Graphics.FromImage(scaledBitmap);
    graph.InterpolationMode = InterpolationMode.High;
    graph.CompositingQuality = CompositingQuality.HighQuality;
    graph.SmoothingMode = SmoothingMode.AntiAlias;
    graph.FillRectangle(brush, new RectangleF(0, 0, width, height));
    graph.DrawImage(rawImage, new Rectangle(0, 0 , scaleWidth, scaleHeight));

    scaledBitmap.Save(fileName, ImageFormat.Png);
    return scaledBitmap;
}

Regex:

[RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", ErrorMessage = "Please enter a valid e-mail adress")]

Or you can use just:

    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }

Update

For newer and still maintained library try jquery.floatThead (as mentioned by Bob Jordan in the comment) instead.

Old Answer

This is a very old answer, the library mentioned below no longer maintained.

I am using StickyTableHeaders on GitHub and it works like charm!

I had to add this css to make the header not transparent though.

table#stickyHeader thead {
  border-top: none;
  border-bottom: none;
  background-color: #FFF;
}

If you want to log to the same file:

command1 >> log_file 2>&1

If you want different files:

command1 >> log_file 2>> err_file

One way to control the locale settings is to set the java system properties user.language and user.region.

I guess this is a fairly old question, but now in 2017. We have neovim, which is a fork of vim which adds terminal support.

So invoking :term would open a terminal window. The beauty of this solution as opposed to using tmux (a terminal multiplexer) is that you'll have the same window bindings as your vim setup. neovim is compatible with vim, so you can basically copy and paste your .vimrc and it will just work.

More advantages are you can switch to normal mode on the opened terminal and you can do basic copy and editing. It is also pretty useful for git commits too I guess, since everything in your buffer you can use in auto-complete.

I'll update this answer since vim is also planning to release terminal support, probably in vim 8.1. You can follow the progress here: https://groups.google.com/forum/#!topic/vim_dev/Q9gUWGCeTXM

Once it's released, I do believe this is a more superior setup than using tmux.

You can directly call the default sort method on the list like this:

myList.sort(String.CASE_INSENSITIVE_ORDER); // reads as the problem statement and cleaner

or:

myList.sort(String::compareToIgnoreCase);  // reads as the problem statement and cleaner

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

If after 6 years you still have the issue, this should solve it :)

cols = [c for c in df.columns if df[c].dtype in ['object', 'datetime64[ns]']]

You can redirect anything or more URL via javascript, Just simple window.location.href with if else

Use this code,

<script>
if(window.location.href == 'old_url')
{
    window.location.href="new_url";
}


//Another url redirect
if(window.location.href == 'old_url2')
{
    window.location.href="new_url2";
}
</script>

You can redirect many URL's by this procedure. Thanks.

Now there is a very useful npm package for this: buffer https://github.com/feross/buffer

It tries to provide an API that is 100% identical to node's Buffer API and allow:

• convert typed array to buffer: https://github.com/feross/buffer#convert-typed-array-to-buffer
• convert buffer to typed array: https://github.com/feross/buffer#convert-buffer-to-typed-array

and few more.

For setting up path in Mac two methods can be followed.

1. Creating a file for variable name and paste the path there under /etc/paths.d and source the file to profile_bashrc.

2. Export path variable in ~/.profile_bashrc as

   export VARIABLE_NAME = $(PATH_VALUE)

AND source the the path. Its simple and stable.

You can set any path variable by Mac terminal or in linux also.

I solved this problem by adding C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Runtime.Serialization.dll in the reference

public static byte[] hexToBin(String str)
    {
        int len = str.length();
        byte[] out = new byte[len / 2];
        int endIndx;

        for (int i = 0; i < len; i = i + 2)
        {
            endIndx = i + 2;
            if (endIndx > len)
                endIndx = len - 1;
            out[i / 2] = (byte) Integer.parseInt(str.substring(i, endIndx), 16);
        }
        return out;
    }

An extra pair of rabbits' ears should do the trick.

start "" "C:\Program...

START regards the first quoted parameter as the window-title, unless it's the only parameter - and any switches up until the executable name are regarded as START switches.

Don't know how to do locale, but javascript is a client side technology.

usersLocalTime = new Date();

will have the client's time and date in it (as reported by their browser, and by extension the computer they are sitting at). It should be trivial to include the server's time in the response and do some simple math to guess-timate offset.

A pure JavaScript solution ought to be offered as well, as the solution is not difficult:

var a = [].filter.call(el.attributes, function(at) { return /^data-/.test(at.name); });

This gives an array of attribute objects, which have name and value properties:

if (a.length) {
    var firstAttributeName = a[0].name;
    var firstAttributeValue = a[0].value;
}

Edit: To take it a step further, you can get a dictionary by iterating the attributes and populating a data object:

var data = {};
[].forEach.call(el.attributes, function(attr) {
    if (/^data-/.test(attr.name)) {
        var camelCaseName = attr.name.substr(5).replace(/-(.)/g, function ($0, $1) {
            return $1.toUpperCase();
        });
        data[camelCaseName] = attr.value;
    }
});

You could then access the value of, for example, data-my-value="2" as data.myValue;

jsfiddle.net/3KFYf/33

Edit: If you wanted to set data attributes on your element programmatically from an object, you could:

Object.keys(data).forEach(function(key) {
    var attrName = "data-" + key.replace(/[A-Z]/g, function($0) {
        return "-" + $0.toLowerCase();
    });
    el.setAttribute(attrName, data[key]);
});

jsfiddle.net/3KFYf/34

EDIT: If you are using babel or TypeScript, or coding only for es6 browsers, this is a nice place to use es6 arrow functions, and shorten the code a bit:

var a = [].filter.call(el.attributes, at => /^data-/.test(at.name));

I don't like any of the other answers so far (except perhaps the one by SwiftDeveloper), because they either require you to deserialize your JSON, only for it to be serialized again, or care about the structure of the JSON itself.

The correct answer has been posted by afrodev in another question. You should go and upvote it.

Below is just my adaption, with some minor changes (primarily explicit UTF-8 charset).

let urlString = "https://example.org/some/api"
let json = "{\"What\":\"Ever\"}"

let url = URL(string: urlString)!
let jsonData = json.data(using: .utf8, allowLossyConversion: false)!

var request = URLRequest(url: url)
request.httpMethod = HTTPMethod.post.rawValue
request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData

Alamofire.request(request).responseJSON {
    (response) in

    print(response)
}

From the spring docs

Spring can be easily integrated into any Java-based web framework. All you need to do is to declare the ContextLoaderListener in your web.xml and use a contextConfigLocation to set which context files to load.

The <context-param>:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>

<listener>
   <listener-class>
        org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener> 

You can then use the WebApplicationContext to get a handle on your beans.

WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());
SomeBean someBean = (SomeBean) ctx.getBean("someBean");

See http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/context/support/WebApplicationContextUtils.html for more info

I am try to catch your point.I hope it is helpful.....

if (session.isNew()){
     title = "Welcome to my website";
     session.setAttribute(userIDKey, userID);

Try this

String[] array = values.split("\\|",-1); 

You can do objects the JavaScript way... It makes no sense but it works ;)

>>> def FakeObject():
...   def test():
...     print "foo"
...   FakeObject.test = test
...   return FakeObject
>>> x = FakeObject()
>>> x.test()
foo

If the body of the arrow function is wrapped in curly braces, it is not implicitly returned. Wrap the object in parentheses. It would look something like this.

p => ({ foo: 'bar' })

By wrapping the body in parens, the function will return { foo: 'bar }.

Hopefully, that solves your problem. If not, I recently wrote an article about Arrow functions which covers it in more detail. I hope you find it useful. Javascript Arrow Functions

c = np.array([[1,2,3],[4,5,6]])

list(c.flatten())

To hide both letter e and minus sign - just go for:

onkeydown="return event.keyCode !== 69 && event.keyCode !== 189"

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

Simply Use:

String Uri = request.getRequestURL()+"?"+request.getQueryString();

If your date is not in format standar yyyy-mm-dd (2017-02-06) for example 20/06/2016. You can use this code

var parts ='01/07/2016'.val().split('/');
var d1 = Number(parts[2] + parts[1] + parts[0]);
parts ='20/06/2016'.val().split('/');
var d2 = Number(parts[2] + parts[1] + parts[0]);
return d1 > d2

You could use this:

a = ((4.0, 4, 4.0), (3.0, 3, 3.6), (3.5, 6, 4.8))
a = np.array(a)
a[:,0]
returns >>> array([4. , 3. , 3.5])

the answers on this page eluded me until i found the show package details option

This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.

The overall dimensions of a range are in its Width and Height properties.

Dim r As Range
Set r = ActiveSheet.Range("A4:H12")

Debug.Print r.Width
Debug.Print r.Height

It wants the full time in DD-MM-YYYY_HH-MM-SS.TT where TT is the ticks. The exception says it all.

f you want to use $.getJSON() you can add the following before the call :

$.ajaxSetup({
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8"
});

The correct way to do this is:

typedef void (*callback_function)(void); // type for conciseness

callback_function disconnectFunc; // variable to store function pointer type

void D::setDisconnectFunc(callback_function pFunc)
{
    disconnectFunc = pFunc; // store
}

void D::disconnected()
{
    disconnectFunc(); // call
    connected = false;
}

You may use something like this to call the handler written on click:

import { shallow } from 'enzyme'; // Mount is not required

page = <MyCoolPage />;
pageMounted = shallow(page);

// The below line will execute your click function
pageMounted.instance().yourOnClickFunction();

You could use shallow clones (git > 1.9):

git clone --depth depth remote-url

Further reading: http://blogs.atlassian.com/2014/05/handle-big-repositories-git/

you can use this code

    public static String getSubString(String mainString, String lastString, String startString) {
    String endString = "";
    int endIndex = mainString.indexOf(lastString);
    int startIndex = mainString.indexOf(startString);
    Log.d("message", "" + mainString.substring(startIndex, endIndex));
    endString = mainString.substring(startIndex, endIndex);
    return endString;
}

in this mainString is a Super string.like "I_AmANDROID.Devloper" and lastString is a string like"." and startString is like"_". so this function returns "AmANDROID". enjoy your code time.:)

Alternative built-in: trim()

trim — Strip whitespace (or other characters) from the beginning and end of a string
Description ¶
trim ( string $str [, string $character_mask = " \t\n\r\0\x0B" ] ) : string

This function returns a string with whitespace stripped from the beginning and end of str.
Without the second parameter, trim() will strip these characters:

    " " (ASCII 32 (0x20)), an ordinary space.
    "\t" (ASCII 9 (0x09)), a tab.
    "\n" (ASCII 10 (0x0A)), a new line (line feed).
    "\r" (ASCII 13 (0x0D)), a carriage return.
    "\0" (ASCII 0 (0x00)), the NUL-byte.
    "\x0B" (ASCII 11 (0x0B)), a vertical tab.

It's there to remove line breaks from different kinds of text files, but does not handle html.

This usually happens when you use two ssh keys to access two different GitHub account.

Follow these steps to fix this it look too long but trust me it won't take more than 5 minutes:

Step-1: Create two ssh key pairs:

ssh-keygen -t rsa -C "[email protected]"

Step-2: It will create two ssh keys here:

~/.ssh/id_rsa_account1
~/.ssh/id_rsa_account2

Step-3: Now we need to add these keys:

ssh-add ~/.ssh/id_rsa_account2
ssh-add ~/.ssh/id_rsa_account1

• You can see the added keys list by using this command: ssh-add -l
• You can remove old cached keys by this command: ssh-add -D

Step-4: Modify the ssh config

cd ~/.ssh/
touch config

subl -a config or code config or nano config

Step-5: Add this to config file:

#Github account1
Host github.com-account1
    HostName github.com
    User account1
    IdentityFile ~/.ssh/id_rsa_account1

#Github account2
Host github.com-account2
    HostName github.com
    User account2
    IdentityFile ~/.ssh/id_rsa_account2

Step-6: Update your .git/config file:

Step-6.1: Navigate to account1's project and update host:

[remote "origin"]
        url = [email protected]:account1/gfs.git

If you are invited by some other user in their git Repository. Then you need to update the host like this:

[remote "origin"]
            url = [email protected]:invitedByUserName/gfs.git

Step-6.2: Navigate to account2's project and update host:

[remote "origin"]
        url = [email protected]:account2/gfs.git

Step-7: Update user name and email for each repository separately if required this is not an amendatory step:

Navigate to account1 project and run these:

git config user.name "account1"
git config user.email "[email protected]" 

Navigate to account2 project and run these:

git config user.name "account2"
git config user.email "[email protected]" 

Depending on your specific case, you could do:

>>> vars(x) == vars(y)
True

Something like:

var divided = str.split("/~/");
var name=divided[0];
var street = divided[1];

Have you tried using the [FromUri] attribute when sending parameters over the query string.

Here is an example:

[HttpGet]
[Route("api/department/getndeptsfromid")]
public List<Department> GetNDepartmentsFromID([FromUri]int FirstId, [FromUri] int CountToFetch)
{
    return HHSService.GetNDepartmentsFromID(FirstId, CountToFetch);
}

Include this package at the top also, using System.Web.Http;

This happens to me when I do not clean solution before build new .edmx designer. So just don’t forget to clean solution before you build new .edmx designer. This helps me to skip lot more issues with this one. Bellow the navigation details provided incase you are new in visual studio.

I'm using IBM Data Studio v 3.1.1.0 with an underlying DB2 for z/OS and the accepted answer didn't work for me. If you're using IBM Data Studio (v3.1.1.0) you can:

2. Select tables or views;
3. On the right panel, right click your table or view;
4. There should be an option to extract/download data, in portuguese it says: "Descarregar -> Com sql" - something like "Download -> with sql;"

RewriteBase is only applied to the target of a relative rewrite rule.

• Using RewriteBase like this...

  RewriteBase /folder/
  RewriteRule a\.html b.html
  

• is essentially the same as...

  RewriteRule a\.html /folder/b.html
  

• But when the .htaccess file is inside /folder/ then this also points to the same target:

  RewriteRule a\.html b.html
  

Although the docs imply always using a RewriteBase, Apache usually detects it correctly for paths under the DocumentRoot unless:

• You are using Alias directives

• You are using .htaccess rewrite rules to perform HTTP redirects (rather than just silent rewriting) to relative URLs

In these cases, you may find that you need to specify the RewriteBase.

However, since it's a confusing directive, it's generally better to simply specify absolute (aka 'root relative') URIs in your rewrite targets. Other developers reading your rules will grasp these more easily.

Quoting from Jon Lin's excellent in-depth answer here:

In an htaccess file, mod_rewrite works similar to a <Directory> or <Location> container. and the RewriteBase is used to provide a relative path base.

For example, say you have this folder structure:

DocumentRoot
|-- subdir1
`-- subdir2
    `-- subsubdir

So you can access:

• http://example.com/ (root)
• http://example.com/subdir1 (subdir1)
• http://example.com/subdir2 (subdir2)
• http://example.com/subdir2/subsubdir (subsubdir)

The URI that gets sent through a RewriteRule is relative to the directory containing the htaccess file. So if you have:

RewriteRule ^(.*)$ - 

• In the root htaccess, and the request is /a/b/c/d, then the captured URI ($1) is a/b/c/d.
• If the rule is in subdir2 and the request is /subdir2/e/f/g then the captured URI is e/f/g.
• If the rule is in the subsubdir, and the request is /subdir2/subsubdir/x/y/z, then the captured URI is x/y/z.

The directory that the rule is in has that part stripped off of the URI. The rewrite base has no affect on this, this is simply how per-directory works.

What the rewrite base does do, is provide a URL-path base (not a file-path base) for any relative paths in the rule's target. So say you have this rule:

RewriteRule ^foo$ bar.php [L]

The bar.php is a relative path, as opposed to:

RewriteRule ^foo$ /bar.php [L]

where the /bar.php is an absolute path. The absolute path will always be the "root" (in the directory structure above). That means that regardless of whether the rule is in the "root", "subdir1", "subsubdir", etc. the /bar.php path always maps to http://example.com/bar.php.

But the other rule, with the relative path, it's based on the directory that the rule is in. So if

RewriteRule ^foo$ bar.php [L]

is in the "root" and you go to http://example.com/foo, you get served http://example.com/bar.php. But if that rule is in the "subdir1" directory, and you go to http://example.com/subdir1/foo, you get served http://example.com/subdir1/bar.php. etc. This sometimes works and sometimes doesn't, as the documentation says, it's supposed to be required for relative paths, but most of the time it seems to work. Except when you are redirecting (using the R flag, or implicitly because you have http://host in your rule's target). That means this rule:

RewriteRule ^foo$ bar.php [L,R]

if it's in the "subdir2" directory, and you go to http://example.com/subdir2/foo, mod_rewrite will mistake the relative path as a file-path instead of a URL-path and because of the R flag, you'll end up getting redirected to something like: http://example.com/var/www/localhost/htdocs/subdir1. Which is obviously not what you want.

This is where RewriteBase comes in. The directive tells mod_rewrite what to append to the beginning of every relative path. So if I have:

RewriteBase /blah/
RewriteRule ^foo$ bar.php [L]

in "subsubdir", going to http://example.com/subdir2/subsubdir/foo will actually serve me http://example.com/blah/bar.php. The "bar.php" is added to the end of the base. In practice, this example is usually not what you want, because you can't have multiple bases in the same directory container or htaccess file.

In most cases, it's used like this:

RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]

where those rules would be in the "subdir1" directory and

RewriteBase /subdir2/subsubdir/
RewriteRule ^foo$ bar.php [L]

would be in the "subsubdir" directory.

This partly allows you to make your rules portable, so you can drop them in any directory and only need to change the base instead of a bunch of rules. For example if you had:

RewriteEngine On
RewriteRule ^foo$ /subdir1/bar.php [L]
RewriteRule ^blah1$ /subdir1/blah.php?id=1 [L]
RewriteRule ^blah2$ /subdir1/blah2.php [L]
...

such that going to http://example.com/subdir1/foo will serve http://example.com/subdir1/bar.php etc. And say you decided to move all of those files and rules to the "subsubdir" directory. Instead of changing every instance of /subdir1/ to /subdir2/subsubdir/, you could have just had a base:

RewriteEngine On
RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]
RewriteRule ^blah1$ blah.php?id=1 [L]
RewriteRule ^blah2$ blah2.php [L]
...

And then when you needed to move those files and the rules to another directory, just change the base:

RewriteBase /subdir2/subsubdir/

and that's it.

For Intel graphics and AMD/ATI opensource graphics drivers

Find the "Device" section of /etc/X11/xorg.conf which contains one of the following directives:

• Driver "intel"
• Driver "radeon"
• Driver "fglrx"

And add the following line to that section:

Option     "SwapbuffersWait"       "false"

And run your application with vblank_mode environment variable set to 0:

$ vblank_mode=0 glxgears

For Nvidia graphics with the proprietary Nvidia driver

$ echo "0/SyncToVBlank=0" >> ~/.nvidia-settings-rc

The same change can be made in the nvidia-settings GUI by unchecking the option at X Screen 0 / OpenGL Settings / Sync to VBlank. Or, if you'd like to just test the setting without modifying your ~/.nvidia-settings-rc file you can do something like:

$ nvidia-settings --load-config-only --assign="SyncToVBlank=0"  # disable vertical sync
$ glxgears  # test it out
$ nvidia-settings --load-config-only  # restore your original vertical sync setting

>>> import itertools
>>> int(''.join(itertools.takewhile(lambda s: s.isdigit(), string1)))

Discussing nested classes...

The difference is that a nested class declaration that is also static can be instantiated outside of the enclosing class.

When you have a nested class declaration that is not static, Java won't let you instantiate it except via the enclosing class. The object created out of the inner class is linked to the object created from the outer class, so the inner class can reference the fields of the outer.

But if it's static, then the link does not exist, the outer fields cannot be accessed (except via an ordinary reference like any other object) and you can therefore instantiate the nested class by itself.

I found ljust() and rjust() very useful to print a string at a fixed width or fill out a Python string with spaces.

An example

print('123.00'.rjust(9))
print('123456.89'.rjust(9))

# expected output  
   123.00
123456.89

For your case, you case use fstring to print

for prefix in unique:
    if prefix != "":
        print(f"value  {prefix.ljust(3)} - num of occurrences = {string.count(str(prefix))}")

Expected Output

value  a   - num of occurrences = 1
value  ab  - num of occurrences = 1
value  abc - num of occurrences = 1
value  b   - num of occurrences = 1
value  bc  - num of occurrences = 1
value  bcd - num of occurrences = 1
value  c   - num of occurrences = 1
value  cd  - num of occurrences = 1
value  d   - num of occurrences = 1

You can change 3 to the highest length of your permutation string.

condition1 = False
condition2 = False
val = -1
#here is the function getstuff is not defined, i hope you define it before
#calling it into while loop code

while condition1 and condition2 is False and val == -1:
#as you can see above , we can write that in a simplified syntax.
    val,something1,something2 = getstuff()

    if something1 == 10:
        condition1 = True

    elif something2 == 20:
# here you don't have to use "if" over and over, if have to then write "elif" instead    
    condition2 = True
# ihope it can be helpfull

Another way to accomplish this would be using a linq statement. The recomended answer did not work for me in .NetCore2.0. I was able to figure it out however and below would also work if you are using newer technology.

[HttpPost]
public ActionResult Report(FormCollection collection)
{
    var listofIDs = collection.ToList().Select(x => x.ToString());
    List<Dinner> dinners = new List<Dinner>();
    dinners = repository.GetDinners(listofIDs);
    return View(dinners);
}

Check this.

UDE

This is a port of Mozilla Universal Charset Detector and you can use it like this...

public static void Main(String[] args)
{
    string filename = args[0];
    using (FileStream fs = File.OpenRead(filename)) {
        Ude.CharsetDetector cdet = new Ude.CharsetDetector();
        cdet.Feed(fs);
        cdet.DataEnd();
        if (cdet.Charset != null) {
            Console.WriteLine("Charset: {0}, confidence: {1}", 
                 cdet.Charset, cdet.Confidence);
        } else {
            Console.WriteLine("Detection failed.");
        }
    }
}

I have done the following steps to get rid of this issue. Login into the MySQL in your machine using (sudo mysql -p -u root) and hit the following queries.

1. CREATE USER 'jack'@'localhost' IDENTIFIED WITH mysql_native_password BY '<<any password>>';

2. GRANT ALL PRIVILEGES ON *.* TO 'jack'@'localhost';

3. SELECT user,plugin,host FROM mysql.user WHERE user = 'root';
+------+-------------+-----------+
| user | plugin      | host      |

+------+-------------+-----------+

| root | auth_socket | localhost |

+------+-------------+-----------+

4. ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<<any password>>';

5. FLUSH PRIVILEGES;

Please try it once if you are still getting the error. I hope this code will help you a lot !!

For business data, if the data is private I would use a secured connection, otherwise a forms authentication is sufficient.

If you do decide to use a secured connection, please note that I do not have experience with securing websites, I am just recanting off what I encountered during my own personal experience. If I am wrong in anyway, please feel free to correct me.

What should I do to prepare my website for https. (Do I need to alter the code / Config)

In order to enable SSL (Secure Sockets Layer) for your website, you would need to set-up a certificate, code or config is not altered.

I have enabled SSL for an internal web-server, by using OpenSSL and ActivePerl from this online tutorial. If this is used for a larger audience (my audience was less than 10 people) and is in the public domain, I suggest seeking professional alternatives.

Is SSL and https one and the same...

Not exactly, but they go hand in hand! SSL ensures that data is encrypted and decrypted back and forth while you are viewing the website, https is the URI that is need to access the secure website. You will notice when you try to access http://secure.mydomain.com it displays an error message.

Do I need to apply with someone to get some license or something.

You would not need to obtain a license, but rather a certificate. You can look into companies that offer professional services with securing websites, such as VeriSign as an example.

Do I need to make all my pages secured or only the login page...

Once your certificate is enabled for mydomain.com every page that falls under *.mydomain.com will be secured.

I'm using NodeJS and got the same error. Like the other answers, the problem was also because JQuery needed to be loaded before Bootstrap; however, because of the NodeJS characteristics, this change had to be aplied in the pipeline.js file.

The change in pipeline.js was like this:

var jsFilesToInject = [
  // Dependencies like jQuery, or Angular are brought in here
  'js/dependencies/angular.1.3.js',
  'js/dependencies/jquery.js',
  'js/dependencies/bootstrap.js',
  'js/dependencies/**/*.js',
];

I'm also using grunt to help, and it automatically changed the order in the main html page:

<!--SCRIPTS-->
  <script src="/js/dependencies/angular.1.3.js"></script>
  <script src="/js/dependencies/jquery.js"></script>
  <script src="/js/dependencies/bootstrap.js"></script>
  <!-- other dependencies -->
<!--SCRIPTS END-->

Hope it helps! You didn't said what your environment was, so I decided to post this answer.

Check Demo: https://stackblitz.com/edit/angular-6-checkbox?embed=1&file=src/app/app.component.html

  CheckBox: use change event to call the function and pass the event.

<label class="container">    
   <input type="checkbox" [(ngModel)]="theCheckbox"  data-md-icheck 
    (change)="toggleVisibility($event)"/>
      Checkbox is <span *ngIf="marked">checked</span><span 
     *ngIf="!marked">unchecked</span>
     <span class="checkmark"></span>
</label>
 <div>And <b>ngModel</b> also works, it's value is <b>{{theCheckbox}}</b></div>

I found that even after following all the steps above, I was still getting errors saying that my Maven dependencies (i.e. pom.xml) were pointing to jar files that didn't exist.

Viewing the errors in the Problems tab, for some reason these were still pointing to the old location of my repository. This was probably because I'd changed the location of my Maven repository since creating the workspace and project.

This can be easily solved by deleting the project from the Eclipse workspace, and re-adding it again through Package Explorer -> R/Click -> Import... -> Existing Projects.

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

Try this :

ImageView imageview = (ImageView)findViewById(R.id.your_imageview_id);
Bitmap bmp = BitmapFactory.decodeFile(new java.net.URL(your_url).openStream());  
imageview.setImageBitmap(bmp);

You can also try this : Android-Universal-Image-Loader for efficiently loading your image from URL

You can use

public List<E> addToListStart(List<E> list, E obj){
list.add(0,obj);
return (List<E>)list;

}

Change E with your datatype

If deleting the oldest element is necessary then you can add:

list.remove(list.size()-1); 

before return statement. Otherwise list will add your object at beginning and also retain oldest element.

This will delete last element in list.

here is a pure-javascript, minimalistic approach. I use JQuery but you can use any library (or even no libraries at all).

<html>
    <head>
        <title>An example</title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script>
            function call_counter(url, pk) {
                window.open(url);
                $.get('YOUR_VIEW_HERE/'+pk+'/', function (data) {
                    alert("counter updated!");
                });
            }
        </script>
    </head>
    <body>
        <button onclick="call_counter('http://www.google.com', 12345);">
            I update object 12345
        </button>
        <button onclick="call_counter('http://www.yahoo.com', 999);">
            I update object 999
        </button>
    </body>
</html>

Alternative approach

Instead of placing the JavaScript code, you can change your link in this way:

<a target="_blank" 
    class="btn btn-info pull-right" 
    href="{% url YOUR_VIEW column_3_item.pk %}/?next={{column_3_item.link_for_item|urlencode:''}}">
    Check It Out
</a>

and in your views.py:

def YOUR_VIEW_DEF(request, pk):
    YOUR_OBJECT.objects.filter(pk=pk).update(views=F('views')+1)
    return HttpResponseRedirect(request.GET.get('next')))

When you need to toggle an element away, and you don't need to animate the margin property. You could try margin-top: -999999em. Just don't transition all.

My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:

The wrapper class:

public class ZippedFileInputStream extends InputStream {

    private ZipInputStream is;

    public ZippedFileInputStream(ZipInputStream is){
        this.is = is;
    }

    @Override
    public int read() throws IOException {
        return is.read();
    }

    @Override
    public void close() throws IOException {
        is.closeEntry();
    }

}

The use of it:

    ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));

    while((entry = zipInputStream.getNextEntry())!= null) {

     ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);

     //... perform whatever logic you want here with ZippedFileInputStream 

     // note that this will only close the current entry stream and not the ZipInputStream
     archivedFileInputStream.close();

    }
    zipInputStream.close();

One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.

The .ToLowerCase version is not going to be faster - it involves an extra string allocation (which must later be collected), etc.

Personally, I'd use

string.Equals(val, "astringvalue",  StringComparison.OrdinalIgnoreCase)

this avoids all the issues of culture-sensitive strings, but as a consequence it avoids all the issues of culture-sensitive strings. Only you know whether that is OK in your context.

Using the string.Equals static method avoids any issues with val being null.

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

I agree with @GregoryKlopper that the right way to solve the general problem of finding Waldo (or any object of interest) in an arbitrary image would be to train a supervised machine learning classifier. Using many positive and negative labeled examples, an algorithm such as Support Vector Machine, Boosted Decision Stump or Boltzmann Machine could likely be trained to achieve high accuracy on this problem. Mathematica even includes these algorithms in its Machine Learning Framework.

The two challenges with training a Waldo classifier would be:

1. Determining the right image feature transform. This is where @Heike's answer would be useful: a red filter and a stripped pattern detector (e.g., wavelet or DCT decomposition) would be a good way to turn raw pixels into a format that the classification algorithm could learn from. A block-based decomposition that assesses all subsections of the image would also be required ... but this is made easier by the fact that Waldo is a) always roughly the same size and b) always present exactly once in each image.
2. Obtaining enough training examples. SVMs work best with at least 100 examples of each class. Commercial applications of boosting (e.g., the face-focusing in digital cameras) are trained on millions of positive and negative examples.

A quick Google image search turns up some good data -- I'm going to have a go at collecting some training examples and coding this up right now!

However, even a machine learning approach (or the rule-based approach suggested by @iND) will struggle for an image like the Land of Waldos!

It seems to me that when it displays the "For development purposes only", one cannot see the map configurations as well while developing(or rather playing around with the configurations). In my case I have not enabled billing to be associated with the API I am using and I am thinking that's the reason why its behaving this way.

In your form, You might have hidden input having required attribute:

• <input type="hidden" required />
• <input type="file" required style="display: none;"/>

The form can't focus on those elements, you have to remove required from all hidden inputs, or implement a validation function in javascript to handle them if you really require a hidden input.

The issue I had was also with serialization. The cause was some of my DTO/business classes and properties were renamed or deleted without updating the service reference. I'm surprised I didn't get a contract filter mismatch error instead. But updating the service ref fixed the error for me (same error as OP).

There seems to be a major mistake in almost all the current answers in that they show BOTH GET and POST data. Not ONLY POST data.

The issue with your code as the accepted answer mentioned is that you did not import the facade. This can imported by adding the following at the top:

use Request;

public function add_question(Request $request)
{
    return Request::post();
}

You can also use the global request method like so (mentioned by @Canaan Etai), with no import required:

request()->post();

However, a better approach to importing Request in a controller method is by dependency injection as mentioned in @shuvrow answer:

use Illuminate\Http\Request;

public function add_question(Request $request)
{
    return $request->post();
}

More information about DI can be found here:

• https://laravel.com/docs/5.6/container
• https://laravel.com/docs/5.6/controllers#dependency-injection-and-controllers

In either case, you should use:

// Show only POST data
$request->post(); // DI
request()->post(); // global method
Request::post(); // facade

// Show only GET data
$request->query(); // DI
request()->query(); // global method
Request::query(); // facade

// Show all data (i.e. both GET and POST data)
$request->all(); // DI
request()->all(); // global method
Request::all(); // facade

This is the method I'm using in a project I am currently working on.

var exec = require('child_process').exec;
function execute(command, callback){
    exec(command, function(error, stdout, stderr){ callback(stdout); });
};

Example of retrieving a git user:

module.exports.getGitUser = function(callback){
    execute("git config --global user.name", function(name){
        execute("git config --global user.email", function(email){
            callback({ name: name.replace("\n", ""), email: email.replace("\n", "") });
        });
    });
};

If you want a specific word from the line, awk might be useful, e.g.

$ echo $LINE | awk '{print $2}'

Prints the second whitespace separated word in $LINE. You can also split on other characters, e.g.

$ echo "5:6:7" | awk -F: '{print $2}'
6

This error means that the MVC framework can't find a value for your id property that you pass as an argument to the Edit method.

MVC searches for these values in places like your route data, query string and form values.

For example the following will pass the id property in your query string:

/Edit?id=1

A nicer way would be to edit your routing configuration so you can pass this value as a part of the URL itself:

/Edit/1

This process where MVC searches for values for your parameters is called Model Binding and it's one of the best features of MVC. You can find more information on Model Binding here.

Create a Map or a Set, and using "on connection" event set to it each connected socket, in reverse "once disconnect" event delete that socket from the Map we created earlier

import * as Server from 'socket.io';

const io = Server();
io.listen(3000);

const connections = new Set();

io.on('connection', function (s) {

  connections.add(s);

  s.once('disconnect', function () {
    connections.delete(s);
  });

});

Extending Muein's thoughts for those who prefer to edit files directly over running commands in git-bash or terminal.

Go to the .git directory of your project (project root on your local machine) and open the 'config' file. Then look for [remote "origin"] and set the url config as follows:

[remote "origin"]
    #the address part will be different depending upon the service you're using github, bitbucket, unfuddle etc.
    url = [email protected]:<username>/<projectname>.git

You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.

import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))

I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse() and fromstring() methods.

Double check if you are not able to use keys.

Otherwise use expect:

#!/usr/bin/expect -f
spawn ssh [email protected]
expect "assword:"
send "mypassword\r"
interact

Instead of doing file_put_contents(***WebSiteURL***...) you need to use the server path to /cache/lang/file.php (e.g. /home/content/site/folders/filename.php).

You cannot open a file over HTTP and expect it to be written. Instead you need to open it using the local path.

Note that Charity Leschinski's answer may have a bit of an issue when there is some delay in the response. eg:
lparstat 1 5 returns one response line and works,
lparstat 5 1 should return 5 lines, but only returns the first

I've put the command output while inside another ... I'm sure there is a better way, I had to do this as a quick fix

        while (commandOutput.available() > 0) {
            while (readByte != 0xffffffff) {
                outputBuffer.append((char) readByte);
                readByte = commandOutput.read();
            }
            try {Thread.sleep(1000);} catch (Exception ee) {}
        }

If your database is down then during login as SYSDBA you can assume this. While login command will be executed like sqlplus sys/sys_password as sysdba that time you will get "connected to idle instance" reply from database. This message indicates your database is down. You should need to check first alert.log file about why database is down. If you found it was downed normally then you can issue "startup" command for starting database and after that execute your create user command. If you found database is having issue like missing datafile or something else then you need to recover database first and open database for executing your create user command.

"alter database open" command only accepted by database while it is on Mount stage. If database is down then it won't accept "alter database open" command.

I should this On Windows, environment variable expansion is %BUILD_NUMBER%

If the functions are re-written with completely different variables and we call id on them, it then illustrates the point well. I didn't get this at first and read jfs' post with the great explanation, so I tried to understand/convince myself:

def f(y, z):
    y = 2
    z.append(4)
    print ('In f():             ', id(y), id(z))

def main():
    n = 1
    x = [0,1,2,3]
    print ('Before in main:', n, x,id(n),id(x))
    f(n, x)
    print ('After in main:', n, x,id(n),id(x))

main()
Before in main: 1 [0, 1, 2, 3]   94635800628352 139808499830024
In f():                          94635800628384 139808499830024
After in main: 1 [0, 1, 2, 3, 4] 94635800628352 139808499830024

z and x have the same id. Just different tags for the same underlying structure as the article says.

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.
