Using sprintf was already proposed by ldueck in a comment, but I think this is worth being an answer:

f(i) = sprintf('f%d', i);

This is in my opinion the most readable solution and also gives some nice flexibility (i.e. when you want to round a float value, use something like %.2f).

As mentioned before, the use of x(end+1) = newElem has the advantage that it allows you to concatenate your vector with a scalar, regardless of whether your vector is transposed or not. Therefore it is more robust for adding scalars.

However, what should not be forgotten is that x = [x newElem] will also work when you try to add multiple elements at once. Furthermore, this generalizes a bit more naturally to the case where you want to concatenate matrices. M = [M M1 M2 M3]

All in all, if you want a solution that allows you to concatenate your existing vector x with newElem that may or may not be a scalar, this should do the trick:

 x(end+(1:numel(newElem)))=newElem

Rather than provide you with a complete list of differences, I'll give you my view on the matter.

If you read carefully the wiki page you provide, you'll often see sentences like "Octave supports both, while MATLAB requires the first" etc. This shows that Octave's developers try to make Octave syntax "superior" to MATLAB's.

This attitude makes Octave lose its purpose completely. The idea behind Octave is (or has become, I should say, see comments below) to have an open source alternative to run m-code. If it tries to be "better", it thus tries to be different, which is not in line with the reasons most people use it for. In my experience, running stuff developed in MATLAB doesn't ever work in one go, except for the really simple, really short stuff -- For any sizable function, I always have to translate a lot of stuff before it works in Octave, if not re-write it from scratch. How this is better, I really don't see...

Also, if you learn Octave, there's a lot of syntax allowed in Octave that's not allowed in MATLAB. Meaning -- code written in Octave often does not work in MATLAB without numerous conversions. It's also not compatible the other way around!

I could go on: The MathWorks has many toolboxes for MATLAB, there's Simulink and its related products for which there really is no equivalent in Octave (yes, you'd have to pay for all that. But often your employer/school does that anyway, and well, it at least exists), proven compliance with several industry standards, testing tools, validation tools, requirement management systems, report generation, a much larger community & user base, etc. etc. etc. MATLAB is only a small part of something much larger. Octave is...just Octave.

So, my advice:

• Find out if your school will pay for MATLAB. Often they will.
• If they don't, and if you can scrape together the money, buy MATLAB and learn to use it properly. In the long run it's the better decision.
• If you really can't get the money -- use Octave, but learn MATLAB's syntax and stay away from Octave-only syntax. (see note)

Why this last point? Because in the sciences, there are often large code bases entirely written in MATLAB. There are professors, engineers, students, professional coders, lots and lots of people who know all the intricate gory details of MATLAB, and not so much of Octave.

If you get a new job, and everyone in your new office speaks Spanish, it's kind of cocky to demand of everyone that they start speaking English from then on, simply because you don't speak/like Spanish. Same with MATLAB and Octave.

NB -- if all downvoters could just leave a comment with their arguments and reasons for disagreeing with me, that'd be great :)

Note: Octave can be run in "traditional mode" (by including the --traditional flag when starting Octave) which makes it give an error when certain Octave-only syntax is used.

Use $HTTP_RAW_POST_DATA instead of $_POST.

It will give you POST data as is.

You will be able to decode it using json_decode() later.

the way I use jsonp like below:

function jsonp(uri) {
    return new Promise(function(resolve, reject) {
        var id = '_' + Math.round(10000 * Math.random());
        var callbackName = 'jsonp_callback_' + id;
        window[callbackName] = function(data) {
            delete window[callbackName];
            var ele = document.getElementById(id);
            ele.parentNode.removeChild(ele);
            resolve(data);
        }

        var src = uri + '&callback=' + callbackName;
        var script = document.createElement('script');
        script.src = src;
        script.id = id;
        script.addEventListener('error', reject);
        (document.getElementsByTagName('head')[0] || document.body || document.documentElement).appendChild(script)
    });
}

then use 'jsonp' method like this:

jsonp('http://xxx/cors').then(function(data){
    console.log(data);
});

Sounds like a good opportunity to use an AlertDialog.

As basic as it seems, Android does not have a built-in dialog to do this (as far as I know). Fortunately, it's just a little extra work on top of creating a standard AlertDialog. You simply need to create an EditText for the user to input data, and set it as the view of the AlertDialog. You can customize the type of input allowed using setInputType, if you need.

If you're able to use a member variable, you can simply set the variable to the value of the EditText, and it will persist after the dialog has dismissed. If you can't use a member variable, you may need to use a listener to send the string value to the right place. (I can edit and elaborate more if this is what you need).

Within your class:

private String m_Text = "";

Within the OnClickListener of your button (or in a function called from there):

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Title");

// Set up the input
final EditText input = new EditText(this);
// Specify the type of input expected; this, for example, sets the input as a password, and will mask the text
input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
builder.setView(input);

// Set up the buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
    @Override
    public void onClick(DialogInterface dialog, int which) {
        m_Text = input.getText().toString();
    }
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
    }
});

builder.show();

Use the following css:

* {
    font: Verdana, Arial, 'sans-serif' !important;/* <-- fonts */
}

The *-selector means any/all elements, but will obviously be on the bottom of the food chain when it comes to overriding more specific selectors.

Note that the !important-flag will render the font-style for * to be absolute, even if other selectors have been used to set the text (for example, the body or maybe a p).

Many hours spent to clarify what was that. Please, read this post to get the advanced .HTACCESS codes and learn what they do.

You can use:

Header append Vary "Accept-Encoding"
#or
Header set Vary "Accept-Encoding"

Use Counter

>>> from collections import Counter
>>> MyList = ["a", "b", "a", "c", "c", "a", "c"]
>>> c = Counter(MyList)
>>> c
Counter({'a': 3, 'c': 3, 'b': 1})

str.replace(/\s|[0-9_]|\W|[#$%^&*()]/g, "") I did sth like this. But there is some people who did it much easier like str.replace(/\W_/g,"");

You know how when you are running JavaScript in the browser, you have access to variables like "window" or Math? You do not have to declare these variables, they have been written for you to use whenever you want.

Well, when you are running a file in the Node.js environment, there is a variable that you can use. It is called "module" It is an object. It has a property called "exports." And it works like this:

In a file that we will name example.js, you write:

example.js

module.exports = "some code";

Now, you want this string "some code" in another file.

We will name the other file otherFile.js

In this file, you write:

otherFile.js

let str = require('./example.js')

That require() statement goes to the file that you put inside of it, finds whatever data is stored on the module.exports property. The let str = ... part of your code means that whatever that require statement returns is stored to the str variable.

So, in this example, the end-result is that in otherFile.js you now have this:

let string = "some code";

• or -

let str = ('./example.js').module.exports

Note:

the file-name that is written inside of the require statement: If it is a local file, it should be the file-path to example.js. Also, the .js extension is added by default, so I didn't have to write it.

You do something similar when requiring node.js libraries, such as Express. In the express.js file, there is an object named 'module', with a property named 'exports'.

So, it looks something like along these lines, under the hood (I am somewhat of a beginner so some of these details might not be exact, but it's to show the concept:

express.js

module.exports = function() {
    //It returns an object with all of the server methods
    return {
        listen: function(port){},
        get: function(route, function(req, res){}){}
     }
}

If you are requiring a module, it looks like this: const moduleName = require("module-name");

If you are requiring a local file, it looks like this: const localFile = require("./path/to/local-file");

(notice the ./ at the beginning of the file name)

Also note that by default, the export is an object .. eg module.exports = {} So, you can write module.exports.myfunction = () => {} before assigning a value to the module.exports. But you can also replace the object by writing module.exports = "I am not an object anymore."

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

$('selector').css('cursor', 'pointer'); // 'default' to revert

I know that may be confusing per your original question, but the "finger" cursor is actually called "pointer".

The normal arrow cursor is just "default".

You can do this with background-size:

html {
    background: url(images/bg.jpg) no-repeat center center fixed; 
    background-size: cover;
}

There are a lot of values other than cover that you can set background-size to, see which one works for you: https://developer.mozilla.org/en-US/docs/Web/CSS/background-size

Spec: https://www.w3.org/TR/css-backgrounds-3/#the-background-size

Try xcorr, it's a built-in function in MATLAB for cross-correlation:

c = xcorr(A_1, A_2);

However, note that it requires the Signal Processing Toolbox installed. If not, you can look into the corrcoef command instead.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

You can write a small script (look at Ian Clelland's answer) called git-commitall which uses several git commands to perform what you want to do.
Place this script in your anywhere in your $PATH. You can call it by git commitall ... very handy!

In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :

@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

using ByteArrayOutputStream and System.setXXX is simple:

private final ByteArrayOutputStream outContent = new ByteArrayOutputStream();
private final ByteArrayOutputStream errContent = new ByteArrayOutputStream();
private final PrintStream originalOut = System.out;
private final PrintStream originalErr = System.err;

@Before
public void setUpStreams() {
    System.setOut(new PrintStream(outContent));
    System.setErr(new PrintStream(errContent));
}

@After
public void restoreStreams() {
    System.setOut(originalOut);
    System.setErr(originalErr);
}

sample test cases:

@Test
public void out() {
    System.out.print("hello");
    assertEquals("hello", outContent.toString());
}

@Test
public void err() {
    System.err.print("hello again");
    assertEquals("hello again", errContent.toString());
}

I used this code to test the command line option (asserting that -version outputs the version string, etc etc)

Edit: Prior versions of this answer called System.setOut(null) after the tests; This is the cause of NullPointerExceptions commenters refer to.

Since glibc version 2.17, the library linking -lrt is no longer required.

The clock_* are now part of the main C library. You can see the change history of glibc 2.17 where this change was done explains the reason for this change:

+* The `clock_*' suite of functions (declared in <time.h>) is now available
+  directly in the main C library.  Previously it was necessary to link with
+  -lrt to use these functions.  This change has the effect that a
+  single-threaded program that uses a function such as `clock_gettime' (and
+  is not linked with -lrt) will no longer implicitly load the pthreads
+  library at runtime and so will not suffer the overheads associated with
+  multi-thread support in other code such as the C++ runtime library.

If you decide to upgrade glibc, then you can check the compatibility tracker of glibc if you are concerned whether there would be any issues using the newer glibc.

To check the glibc version installed on the system, run the command:

ldd --version

(Of course, if you are using old glibc (<2.17) then you will still need -lrt.)

The semantics of Having

To better understand having, you need to see it from a theoretical point of view.

A group by is a query that takes a table and summarizes it into another table. You summarize the original table by grouping the original table into subsets (based upon the attributes that you specify in the group by). Each of these groups will yield one tuple.

The Having is simply equivalent to a WHERE clause after the group by has executed and before the select part of the query is computed.

Lets say your query is:

select a, b, count(*) 
from Table 
where c > 100 
group by a, b 
having count(*) > 10;

The evaluation of this query can be seen as the following steps:

1. Perform the WHERE, eliminating rows that do not satisfy it.
2. Group the table into subsets based upon the values of a and b (each tuple in each subset has the same values of a and b).
3. Eliminate subsets that do not satisfy the HAVING condition
4. Process each subset outputting the values as indicated in the SELECT part of the query. This creates one output tuple per subset left after step 3.

You can extend this to any complex query there Table can be any complex query that return a table (a cross product, a join, a UNION, etc).

In fact, having is syntactic sugar and does not extend the power of SQL. Any given query:

SELECT list 
FROM table
GROUP BY attrList
HAVING condition;

can be rewritten as:

SELECT list from (
   SELECT listatt 
   FROM table 
   GROUP BY attrList) as Name
WHERE condition;

The listatt is a list that includes the GROUP BY attributes and the expressions used in list and condition. It might be necessary to name some expressions in this list (with AS). For instance, the example query above can be rewritten as:

select a, b, count 
from (select a, b, count(*) as count
      from Table 
      where c > 100
      group by a, b) as someName
where count > 10;

The solution you need

Your solution seems to be correct:

SELECT s.sid, s.name
FROM Supplier s, Supplies su, Project pr
WHERE s.sid = su.sid AND su.jid = pr.jid
GROUP BY s.sid, s.name
HAVING COUNT (DISTINCT pr.jid) >= 2 

You join the three tables, then using sid as a grouping attribute (sname is functionally dependent on it, so it does not have an impact on the number of groups, but you must include it, otherwise it cannot be part of the select part of the statement). Then you are removing those that do not satisfy your condition: the satisfy pr.jid is >= 2, which is that you wanted originally.

Best solution to your problem

I personally prefer a simpler cleaner solution:

1. You need to only group by Supplies (sid, pid, jid**, quantity) to find the sid of those that supply at least to two projects.
2. Then join it to the Suppliers table to get the supplier same.

 SELECT sid, sname from
    (SELECT sid from supplies 
    GROUP BY sid, pid 
    HAVING count(DISTINCT jid) >= 2
    ) AS T1
NATURAL JOIN 
Supliers;

It will also be faster to execute, because the join is only done when needed, not all the times.

If you just want to scroll, you could use jQuery's scrollTop method. http://docs.jquery.com/CSS/scrollTop

var table = jQuery( 'table' );
table.scrollTop( table.find( 'tr:last' ).scrollTop() );

Something like that maybe?

$myVar = $someVar ?? 42;

Is equivalent to :

$myVar = isset($someVar) ? $someVar : 42;

For constants, the behaviour is the same when using a constant that already exists :

define("FOO", "bar");
define("BAR", null);

$MyVar = FOO ?? "42";
$MyVar2 = BAR ?? "42";

echo $MyVar . PHP_EOL;  // bar
echo $MyVar2 . PHP_EOL; // 42

However, for constants that don't exist, this is different :

$MyVar3 = IDONTEXIST ?? "42"; // Raises a warning
echo $MyVar3 . PHP_EOL;       // IDONTEXIST

Warning: Use of undefined constant IDONTEXIST - assumed 'IDONTEXIST' (this will throw an Error in a future version of PHP)

Php will convert the non-existing constant to a string.

You can use constant("ConstantName") that returns the value of the constant or null if the constant doesn't exist, but it will still raise a warning. You can prepended the function with the error control operator @ to ignore the warning message :

$myVar = @constant("IDONTEXIST") ?? "42"; // No warning displayed anymore
echo $myVar . PHP_EOL; // 42

$('#myForm').on('change', 'input[type=checkbox]', function() {
    this.checked ? this.value = 'apple' : this.value = 'pineapple';
});

looks good enough as a generic version. You can modify it to meet your needs, if they're specific enough.

also test for exceptions and error conditions, such as file doesn't exist or can't be read, etc.

you can also do the following to save some space:

 byte[] bytes = System.IO.File.ReadAllBytes(filename);

Just from reading that i would have never understood that "$@" expands into a list of separate parameters. Whereas, "$*" is one parameter consisting of all the parameters added together.

If it still makes no sense do this.

It seems to me that the chief difference between the MIT license and GPL is that the MIT doesn't require modifications be open sourced whereas the GPL does.

True - in general. You don't have to open-source your changes if you're using GPL. You could modify it and use it for your own purpose as long as you're not distributing it. BUT... if you DO distribute it, then your entire project that is using the GPL code also becomes GPL automatically. Which means, it must be open-sourced, and the recipient gets all the same rights as you - meaning, they can turn around and distribute it, modify it, sell it, etc. And that would include your proprietary code which would then no longer be proprietary - it becomes open source.

The difference with MIT is that even if you actually distribute your proprietary code that is using the MIT licensed code, you do not have to make the code open source. You can distribute it as a closed app where the code is encrypted or is a binary. Including the MIT-licensed code can be encrypted, as long as it carries the MIT license notice.

is the GPL is more restrictive than the MIT license?

Yes, very much so.

You can use the following wrap to make sync call

this.setState((state =>{_x000D_
  return{_x000D_
    something_x000D_
  }_x000D_

Not sure exactly what your problem is, but try the following:

1. Do the font files exist?
2. Do you need quotes around the URLs?
3. Are you using a CSS3-enabled browser?

Check here for examples, if they don't work for you then you have another problem

Edit:

You have a bunch of repeated declarations in your source, does this work?

@font-face { font-family: Gotham; src: url('../fonts/gothammedium.eot'); }

a { font-family:Gotham,Verdana,Arial; }

It works like this. View.OnClickListenere is defined -

public interface OnClickListener {
    void onClick(View v);
}

As far as we know you cannot instantiate an object OnClickListener, as it doesn't have a method implemented. So there are two ways you can go by - you can implement this interface which will override onClick method like this:

public class MyListener implements View.OnClickListener {
    @Override
    public void onClick (View v) {
         // your code here;
    }
}

But it's tedious to do it each time as you want to set a click listener. So in order to avoid this you can provide the implementation for the method on spot, just like in an example you gave.

setOnClickListener takes View.OnClickListener as its parameter.

REMOTE_ADDR can not be trusted.

Anyway, try

$ipAddress = $_SERVER['REMOTE_ADDR'];
if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)) {
    $ipAddress = array_pop(explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']));
}

Edit: Also, does your server's router have port forwarding enabled? It may be possible that it's messing with the packets.

Security warning: REMOTE_ADDR can be fully trusted! It comes from your own webserver and contains the IP that was used to access it. You don't even need to quote() it for SQL inserts.
But HTTP_X_FORWARDED_FOR is taken directly from the HTTP headers, it can contain the picture of a cat, malicious code, any content. Treat it like that, never trust it.

Here is a java 8 method to find a string in a text file:

for (String toFindUrl : urlsToTest) {
        streamService(toFindUrl);
    }

private void streamService(String item) {
        try (Stream<String> stream = Files.lines(Paths.get(fileName))) {
           stream.filter(lines -> lines.contains(item))
                       .forEach(System.out::println);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Omit the parenthesis:

}

Check it out in the playground

The ruby core itself has no support to convert a string from (upper) camel case to (also known as pascal case) to underscore (also known as snake case).

So you need either to make your own implementation or use an existing gem.

There is a small ruby gem called lucky_case which allows you to convert a string from any of the 10+ supported cases to another case easily:

require 'lucky_case'

# convert to snake case string
LuckyCase.snake_case('CamelCaseString')      # => 'camel_case_string'
# or the opposite way
LuckyCase.pascal_case('camel_case_string')   # => 'CamelCaseString'

You can even monkey patch the String class if you want to:

require 'lucky_case/string'

'CamelCaseString'.snake_case  # => 'camel_case_string'
'CamelCaseString'.snake_case! # => 'camel_case_string' and overwriting original

Have a look at the offical repository for more examples and documentation:

This is a one line solution.

It will run taskkill only if the process is really running otherwise it will just info that it is not running.

tasklist | find /i "notepad.exe" && taskkill /im notepad.exe /F || echo process "notepad.exe" not running.

This is the output in case the process was running:

notepad.exe           1960 Console                   0    112,260 K
SUCCESS: The process "notepad.exe" with PID 1960 has been terminated.

This is the output in case not running:

process "notepad.exe" not running.

RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:

1. Reuses cells while scrolling up/down : this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

2. Decouples list from its container : so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));

3. Animates common list actions : Animations are decoupled and delegated to ItemAnimator. There is more about RecyclerView, but I think these points are the main ones.

So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.

(cd dir && ls)

I stumbled across this attempting to solve the same issue. The installation I am working with uses JBOSS and Hibernate, so I had to do this a different way. For the basic case, you should be able to add zeroDateTimeBehavior=convertToNull to your connection URI as per this configuration properties page.

I found other suggestions across the land referring to putting that parameter in your hibernate config:

In hibernate.cfg.xml:

<property name="hibernate.connection.zeroDateTimeBehavior">convertToNull</property>

In hibernate.properties:

hibernate.connection.zeroDateTimeBehavior=convertToNull

But I had to put it in my mysql-ds.xml file for JBOSS as:

<connection-property name="zeroDateTimeBehavior">convertToNull</connection-property>

Hope this helps someone. :)

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

Personally, I'd code it as tinyint and:

• Either: change it to text on the client, check constraint between 1 and 4
• Or: use a lookup table with a foreign key

Reasons:

• It will take on average 8 bytes to store text, 1 byte for tinyint. Over millions of rows, this will make a difference.

• What about collation? Is "Daily" the same as "DAILY"? It takes resources to do this kind of comparison.

• Finally, what if you want to add "Biweekly" or "Hourly"? This requires a schema change when you could just add new rows to a lookup table.

I have added this function to a library I created vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------

Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.

If you don't use jQuery then the script would be something like this:

function posY(elm) {
    var test = elm, top = 0;

    while(!!test && test.tagName.toLowerCase() !== "body") {
        top += test.offsetTop;
        test = test.offsetParent;
    }

    return top;
}

function viewPortHeight() {
    var de = document.documentElement;

    if(!!window.innerWidth)
    { return window.innerHeight; }
    else if( de && !isNaN(de.clientHeight) )
    { return de.clientHeight; }
    
    return 0;
}

function scrollY() {
    if( window.pageYOffset ) { return window.pageYOffset; }
    return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}

function checkvisible( elm ) {
    var vpH = viewPortHeight(), // Viewport Height
        st = scrollY(), // Scroll Top
        y = posY(elm);
    
    return (y > (vpH + st));
}

Using jQuery is a lot easier:

function checkVisible( elm, evalType ) {
    evalType = evalType || "visible";

    var vpH = $(window).height(), // Viewport Height
        st = $(window).scrollTop(), // Scroll Top
        y = $(elm).offset().top,
        elementHeight = $(elm).height();

    if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
    if (evalType === "above") return ((y < (vpH + st)));
}

This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.

See in action: http://jsfiddle.net/RJX5N/2/

I hope this answers your question.

-- IMPROVED VERSION--

This is a lot shorter and should do it as well:

function checkVisible(elm) {
  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}

with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/

And a version with threshold and mode included:

function checkVisible(elm, threshold, mode) {
  threshold = threshold || 0;
  mode = mode || 'visible';

  var rect = elm.getBoundingClientRect();
  var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
  var above = rect.bottom - threshold < 0;
  var below = rect.top - viewHeight + threshold >= 0;

  return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}

and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/

If you want the remainder of your division problem, just use the actual remainder rules, just like in mathematics. Granted this won't give you a decimal output.

valone = 8
valtwo = 3
x = valone / valtwo
r = valone - (valtwo * x)
print "Answer: %s with a remainder of %s" % (x, r)

If you want to make this in a calculator format, just substitute valone = 8 with valone = int(input("Value One")). Do the same with valtwo = 3, but different vairables obviously.

Use the btoa() function to encode:

console.log(btoa("password")); // cGFzc3dvcmQ=

To decode, you can use the atob() function:

console.log(atob("cGFzc3dvcmQ=")); // password

InputMethodManager inputManager = (InputMethodManager)
                                  getSystemService(Context.INPUT_METHOD_SERVICE); 

inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
                                     InputMethodManager.HIDE_NOT_ALWAYS);

I put this right after the onClick(View v) event.

You need to import android.view.inputmethod.InputMethodManager;

The keyboard hides when you click the button.

Here is an example to get string/value

    public enum Suit
    {
        Spades = 0x10,
        Hearts = 0x11,
        Clubs = 0x12,
        Diamonds = 0x13
    }

    private void print_suit()
    {
        foreach (var _suit in Enum.GetValues(typeof(Suit)))
        {
            int suitValue = (byte)(Suit)Enum.Parse(typeof(Suit), _suit.ToString());
            MessageBox.Show(_suit.ToString() + " value is 0x" + suitValue.ToString("X2"));
        }
    }

    Result of Message Boxes
    Spade value is 0x10
    Hearts value is 0x11
    Clubs value is 0x12
    Diamonds value is 0x13

Use:

git remote add upstream ORIGINAL_REPOSITORY_URL

This will set your upstream to the repository you forked from. Then do this:

git fetch upstream      

This will fetch all the branches including master from the original repository.

Merge this data in your local master branch:

git merge upstream/master

Push the changes to your forked repository i.e. to origin:

git push origin master

Voila! You are done with the syncing the original repository.

On Ubuntu 14.04 none of these suggestions worked. Postfix would override with the logged in system user as the sender. What worked was the following solution listed at this link --> Change outgoing mail address from root@servername - rackspace sendgrid postfix

STEPS:

1) Make sure this is set in /etc/postfix/main.cf:

   smtp_generic_maps = hash:/etc/postfix/generic

2) echo 'www-data [email protected]' >> /etc/postfix/generic

3) sudo postmap /etc/postfix/generic

4) sudo service postfix restart

Assuming you have those values stored in some strings, try this:

function pad (str, max) {
  str = str.toString();
  return str.length < max ? pad("0" + str, max) : str;
}

pad("3", 3);    // => "003"
pad("123", 3);  // => "123"
pad("1234", 3); // => "1234"

var test = "MR 2";
var parts = test.split(" ");
parts[1] = pad(parts[1], 3);
parts.join(" "); // => "MR 002"

Using jQuery:

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');

jsonObj is your JSON object.

Had the exact same error in a procedure. It turns out the user running it (a technical user in our case) did not have sufficient rigths to create a temporary table.

No, there is no way to comment a line in XML and have the comment end automatically on a linebreak.

XML has only one definition for a comment:

'<!--' ((Char - '-') | ('-' (Char - '-')))* '-->'

XML forbids -- in comments to maintain compatibility with SGML.

As said in the documentation:

Must: The clause (query) must appear in matching documents.

Should: The clause (query) should appear in the matching document. In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

In other words, results will have to be matched by all the queries present in the must clause ( or match at least one of the should clauses if there is no must clause.

Since you want your results to satisfy all the queries, you should use must.

You can indeed use filters inside a boolean query.

Instead of telling you how you could execute a certain command (Esc:wq), I can provide you two links that may help you with VIM:

• http://bullium.com/support/vim.html provides an HTML quick reference card
• http://tnerual.eriogerg.free.fr/vim.html provides a PDF quick reference card in several languages, optimized for print-out, fold and put on your desk drawer

However, the best way to learn Vim is not only using it for Git commits, but as a regular editor for your everyday work.

If you're not going to switch to Vim, it's nonsense to keep its commands in mind. In that case, go and set up your favourite editor to use with Git.

This is an implementation of Supr's answer. Also it uses setTimeout instead of setInterval as Mateusz Charytoniuk suggested.

Phantomjs will exit in 1000ms when there isn't any request or response.

// load the module
var webpage = require('webpage');
// get timestamp
function getTimestamp(){
    // or use Date.now()
    return new Date().getTime();
}

var lastTimestamp = getTimestamp();

var page = webpage.create();
page.onResourceRequested = function(request) {
    // update the timestamp when there is a request
    lastTimestamp = getTimestamp();
};
page.onResourceReceived = function(response) {
    // update the timestamp when there is a response
    lastTimestamp = getTimestamp();
};

page.open(html, function(status) {
    if (status !== 'success') {
        // exit if it fails to load the page
        phantom.exit(1);
    }
    else{
        // do something here
    }
});

function checkReadyState() {
    setTimeout(function () {
        var curentTimestamp = getTimestamp();
        if(curentTimestamp-lastTimestamp>1000){
            // exit if there isn't request or response in 1000ms
            phantom.exit();
        }
        else{
            checkReadyState();
        }
    }, 100);
}

checkReadyState();

Your code has no problem. It does print the way you want. Alternatively, you can do this:

printf("%04x",a);

Personally I extract the POST array and then have if(!$login || !$password) then echo fill out the form :)

You should declare Environment Variable for PHP in path, so you could use like this:

C:\Path\to\somewhere>php cli.php

You can do it like this

It's called an initialization list. An initializer list is how you pass arguments to your member variables' constructors and for passing arguments to the parent class's constructor.

If you use = to assign in the constructor body, first the default constructor is called, then the assignment operator is called. This is a bit wasteful, and sometimes there's no equivalent assignment operator.

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

The class java.sql.Date is designed to carry only a date without time, so the conversion result you see is correct for this type. You need to use a java.sql.Timestamp to get a full date with time.

java.util.Date newDate = result.getTimestamp("VALUEDATE");

reduce(lambda x, y : y + x, "hello world")

I agree with tnguyen80's response. Please note that when there is a specific string value in query better to given entire query in double quotes.

For example:

$hive -e "select * from table where city = 'London' and id >=100" > /home/user/outputdirectory/city details.csv

A regular pipe can only connect two related processes. It is created by a process and will vanish when the last process closes it.

A named pipe, also called a FIFO for its behavior, can be used to connect two unrelated processes and exists independently of the processes; meaning it can exist even if no one is using it. A FIFO is created using the mkfifo() library function.

Example

writer.c

#include <fcntl.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    int fd;
    char * myfifo = "/tmp/myfifo";

    /* create the FIFO (named pipe) */
    mkfifo(myfifo, 0666);

    /* write "Hi" to the FIFO */
    fd = open(myfifo, O_WRONLY);
    write(fd, "Hi", sizeof("Hi"));
    close(fd);

    /* remove the FIFO */
    unlink(myfifo);

    return 0;
}

reader.c

#include <fcntl.h>
#include <stdio.h>
#include <sys/stat.h>
#include <unistd.h>

#define MAX_BUF 1024

int main()
{
    int fd;
    char * myfifo = "/tmp/myfifo";
    char buf[MAX_BUF];

    /* open, read, and display the message from the FIFO */
    fd = open(myfifo, O_RDONLY);
    read(fd, buf, MAX_BUF);
    printf("Received: %s\n", buf);
    close(fd);

    return 0;
}

_{Note: Error checking was omitted from the above code for simplicity.}

Essentially it means you don't have the index you are trying to reference. For example:

df = pd.DataFrame()
df['this']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #I haven't yet assigned how long df[data] should be!
print(df)

will give me the error you are referring to, because I haven't told Pandas how long my dataframe is. Whereas if I do the exact same code but I DO assign an index length, I don't get an error:

df = pd.DataFrame(index=[0,1,2,3,4])
df['this']=np.nan
df['is']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #since I've properly labelled my index, I don't run into this problem!
print(df)

Hope that answers your question!

It probably is the # sign like tho others have mentioned because this appears to work just fine.

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

Note: Replace the input element by Material-Ui TextField and define the other properties also.

Create your own class. This seems odd, but a .Net type is inadequate to cover different currencies.

If we setaside the syntax error of print, then the way to use input in multiple scenarios are -

If using python 2.x :

then for evaluated input use "input"
example: number = input("enter a number")

and for string use "raw_input"
example: name = raw_input("enter your name")

If using python 3.x :

then for evaluated result use "eval" and "input"
example: number = eval(input("enter a number"))

for string use "input"
example: name = input("enter your name")

The only way I could get this to work is to pass the JSON as a string and then deserialise it using JavaScriptSerializer.Deserialize<T>(string input), which is pretty strange if that's the default deserializer for MVC 4.

My model has nested lists of objects and the best I could get using JSON data is the uppermost list to have the correct number of items in it, but all the fields in the items were null.

This kind of thing should not be so hard.

    $.ajax({
        type: 'POST',
        url: '/Agri/Map/SaveSelfValuation',
        data: { json: JSON.stringify(model) },
        dataType: 'text',
        success: function (data) {

    [HttpPost]
    public JsonResult DoSomething(string json)
    {
        var model = new JavaScriptSerializer().Deserialize<Valuation>(json);

Usually when you get this problem, it happens because a script is trying to reference an element that doesn't exist yet while the page is loading.

As richie mentioned: "The HTML parser will parse the HTML content from top to bottom..."

So you can add your JavaScript references to the bottom of the HTML file. This will not only improve performance; it will also ensure that all elements referenced in your script files have already been loaded by the HTML parser.

So you could have something like this:

<html>
    <head>
        <!--  Style sheet references and CSS definitions -->
    </head>
    <body>
        <!-- HTML markup and other page content -->

        <!-- JavaScript references. You could include jQuery here as well and do all your scripting here. -->
    </body>
</html>

Just as we refer to scrolling class

$( ".scrolling" ).each( function(){
    var img = $( "img", this );
    $(this).width( img.width() * img.length * 1.2 ) 
})

The @Url.Action() method is proccess on the server-side, so you cannot pass a client-side value to this function as a parameter. You can concat the client-side variables with the server-side url generated by this method, which is a string on the output. Try something like this:

var firstname = "abc";
var username = "abcd";
location.href = '@Url.Action("Display", "Customer")?uname=' + firstname + '&name=' + username;

The @Url.Action("Display", "Customer") is processed on the server-side and the rest of the string is processed on the client-side, concatenating the result of the server-side method with the client-side.

You're trying to remove index.php from your site URL's, correct?

Try setting your $config['uri_protocol'] to REQUEST_URI instead of AUTO.

if the result does not need to be order-preserving, then you can simply use a set

>>> ''.join(set( "aaabcabccd"))
'acbd'
>>>

There is a whole new approach that you may want to consider if what you're after is the power and performance of stored procedures, and the rapid development that tools like Entity Framework provide.

I've taken SQL+ for a test drive on a small project, and it is really something special. You basically add what amounts to comments to your SQL routines, and those comments provide instructions to a code generator, which then builds a really nice object oriented class library based on the actual SQL routine. Kind of like entity framework in reverse.

Input parameters become part of an input object, output parameters and result sets become part of an output object, and a service component provides the method calls.

If you want to use stored procedures, but still want rapid development, you might want to have a look at this stuff.

As Baptiste said, you need to specify the data argument at the geom level. Either

#df1 is the default dataset for all geoms
(plot1 <- ggplot(df1, aes(v, p)) + 
    geom_point() +
    geom_step(data = df2)
)

or

#No default; data explicitly specified for each geom
(plot2 <- ggplot(NULL, aes(v, p)) + 
      geom_point(data = df1) +
      geom_step(data = df2)
)

Majorly there are 3 ways of creating Objects-

Simplest one is using object literals.

const myObject = {}

Though this method is the simplest but has a disadvantage i.e if your object has behaviour(functions in it),then in future if you want to make any changes to it you would have to change it in all the objects.

So in that case it is better to use Factory or Constructor Functions.(anyone that you like)

Factory Functions are those functions that return an object.e.g-

function factoryFunc(exampleValue){
   return{
      exampleProperty: exampleValue 
   }
}

Constructor Functions are those functions that assign properties to objects using "this" keyword.e.g-

function constructorFunc(exampleValue){
   this.exampleProperty= exampleValue;
}
const myObj= new constructorFunc(1);

ArrayList has a indexOf() method. Check the API for more, but here's how it works:

private ArrayList<String> _categories; // Initialize all this stuff

private int getCategoryPos(String category) {
  return _categories.indexOf(category);
}

indexOf() will return exactly what your method returns, fast.

svick's answer is (as usual) excellent.

However, I find Dataflow to be more useful when you actually have large amounts of data to transfer. Or when you need an async-compatible queue.

In your case, a simpler solution is to just use the async-style parallelism:

var ids = new List<string>() { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" };

var customerTasks = ids.Select(i =>
  {
    ICustomerRepo repo = new CustomerRepo();
    return repo.GetCustomer(i);
  });
var customers = await Task.WhenAll(customerTasks);

foreach (var customer in customers)
{
  Console.WriteLine(customer.ID);

I resolved this issue myself. The problem was I had the solution opened in another place. After closing it it works

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

Here is my example of launching bar/QR code scanner from my app if someone finds it useful

Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage("com.google.zxing.client.android");

try 
{
    startActivityForResult(intent, SCAN_REQUEST_CODE);
} 
catch (ActivityNotFoundException e) 
{
    //implement prompt dialog asking user to download the package
    AlertDialog.Builder downloadDialog = new AlertDialog.Builder(this);
    downloadDialog.setTitle(stringTitle);
    downloadDialog.setMessage(stringMessage);
    downloadDialog.setPositiveButton("yes",
            new DialogInterface.OnClickListener() 
            {
                public void onClick(DialogInterface dialogInterface, int i) 
                {
                    Uri uri = Uri.parse("market://search?q=pname:com.google.zxing.client.android");
                    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                    try
                    {
                        myActivity.this.startActivity(intent);
                    }
                    catch (ActivityNotFoundException e)
                    {
                        Dialogs.this.showAlert("ERROR", "Google Play Market not found!");
                    }
                }
            });
    downloadDialog.setNegativeButton("no",
            new DialogInterface.OnClickListener() 
            {
                public void onClick(DialogInterface dialog, int i) 
                {
                    dialog.dismiss();
                }
            });
    downloadDialog.show();
}

    string fileAndPath = @"c:\webserver\public\myCompany\configs\promo.xml";

    string currentDirectory = Path.GetDirectoryName(fileAndPath);

    string fullPathOnly = Path.GetFullPath(currentDirectory);

currentDirectory: c:\webserver\public\myCompany\configs

Custom Scripts

npm run-script <custom_script_name>

or

npm run <custom_script_name>

In your example, you would want to run npm run-script script1 or npm run script1.

See https://docs.npmjs.com/cli/run-script

Lifecycle Scripts

Node also allows you to run custom scripts for certain lifecycle events, like after npm install is run. These can be found here.

For example:

"scripts": {
    "postinstall": "electron-rebuild",
},

This would run electron-rebuild after a npm install command.

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

also see:

CustomErrors mode="Off"

What happens with bittorrent and a DHT is that at the beginning bittorrent uses information embedded in the torrent file to go to either a tracker or one of a set of nodes from the DHT. Then once it finds one node, it can continue to find others and persist using the DHT without needing a centralized tracker to maintain it.

The original information bootstraps the later use of the DHT.

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

PsExec has whatever access rights its launcher has. It runs under regular Windows access control. This means whoever launched PsExec (be it either you, the scheduler, a service etc.) does not have sufficient rights on the target machine, or the target machine is not configured correctly. The first things to do are:

1. Make sure the launcher of PsExec is familiar to the target machine, either via the domain or by having the same user and password defined locally on both machines.
2. Use command line arguments to specify a user that is known to the target machine (-u user -p password)

If this did not solve your problem, make sure the target machine meets the minimum requirements, specified here.

This is what I did and it works try and play around with it. It calculates total,avarage,minimum and maximum.

public static void main(String[] args) {
   int[] score= {56,90,89,99,59,67};
   double avg;
   int sum=0;
   int maxValue=0;
   int minValue=100;

   for(int i=0;i<6;i++){
       sum=sum+score[i];
   if(score[i]<minValue){
    minValue=score[i];
   }
   if(score[i]>maxValue){
    maxValue=score[i];
   }
   }
   avg=sum/6.0;
System.out.print("Max: "+maxValue+"," +" Min: "+minValue+","+" Avarage: "+avg+","+" Sum: "+sum);}

 }

Try to use deep Equal. It will compare nested arrays as well as nested Json.

expect({ foo: 'bar' }).to.deep.equal({ foo: 'bar' });

Please refer to main documentation site.

Use \W which is equivalent to [^a-zA-Z0-9_]. Check the documentation, https://docs.python.org/2/library/re.html

Import re
s =  'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'

update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.

Here is what I did using cairosvg:

from cairosvg import svg2png

svg_code = """
    <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="#000" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
        <circle cx="12" cy="12" r="10"/>
        <line x1="12" y1="8" x2="12" y2="12"/>
        <line x1="12" y1="16" x2="12" y2="16"/>
    </svg>
"""

svg2png(bytestring=svg_code,write_to='output.png')

And it works like a charm!

From the Javadocs for setDisplayOrientation(int) (Requires API level 9):

 public static void setCameraDisplayOrientation(Activity activity,
         int cameraId, android.hardware.Camera camera) {
     android.hardware.Camera.CameraInfo info =
             new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     int rotation = activity.getWindowManager().getDefaultDisplay()
             .getRotation();
     int degrees = 0;
     switch (rotation) {
         case Surface.ROTATION_0: degrees = 0; break;
         case Surface.ROTATION_90: degrees = 90; break;
         case Surface.ROTATION_180: degrees = 180; break;
         case Surface.ROTATION_270: degrees = 270; break;
     }

     int result;
     if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
         result = (info.orientation + degrees) % 360;
         result = (360 - result) % 360;  // compensate the mirror
     } else {  // back-facing
         result = (info.orientation - degrees + 360) % 360;
     }
     camera.setDisplayOrientation(result);
 }

function file_click() {
    document.body.onfocus = () => {
        setTimeout(_=>{
            let file_input = document.getElementById('file_input');
            if (!file_input.value) alert('please choose file ')
            else alert(file_input.value)
            document.body.onfocus = null
        },100)
    }
}

Using setTimeout to get the certain value of the input.

You seem close.

I would try to set the URI like this :

String folderPath = Environment.getExternalStorageDirectory()+"/pathTo/folder";

Intent intent = new Intent();  
intent.setAction(Intent.ACTION_GET_CONTENT);
Uri myUri = Uri.parse(folderPath);
intent.setDataAndType(myUri , "file/*");   
startActivity(intent);

But it's not so different from what you have tried. Tell us if it changes anything ?

Also make sure the targeted folder exists, and have a look on the resulting Uri object before to send it to the intent, it may not be what we are expected.

You have to properly understand what is a "stdafx.h", aka precompiled header. Other questions or Wikipedia will answer that. In many cases a precompiled header can be avoided, especially if your project is small and with few dependencies. In your case, as you probably started from a template project, it was used to include Windows.h only for the _TCHAR macro.

Then, precompiled header is usually a per-project file in Visual Studio world, so:

1. Ensure you have the file "stdafx.h" in your project. If you don't (e.g. you removed it) just create a new temporary project and copy the default one from there;
2. Change the #include <stdafx.h> to #include "stdafx.h". It is supposed to be a project local file, not to be resolved in include directories.

Secondly: it's inadvisable to include the precompiled header in your own headers, to not clutter namespace of other source that can use your code as a library, so completely remove its inclusion in vector.h.

To expand on the above answer_{copied by Shakti}, I have actually been able to measure a performance difference between the two functions.

I was testing performance of variations of the solution to this question and found that the standard deviation and maximum runtimes were larger when using CAST.

_{*Times in milliseconds, rounded to nearest 1/300th of a second as per the precision of the DateTime type}

For me this problem was entirely related to a broken install of Oracle ODP tools for VS. I uninstalled and reinstalled and everything was working again.

if anyone is trying to nest a <mat-radio-group> inside a <mat-form-field> like below, you will get this error

         <mat-form-field>
                <!-- <mat-label>Image Position</mat-label> -->
                <mat-radio-group aria-label="Image Position" [(ngModel)]="section.field_1">
                    <mat-radio-button value="left">Left</mat-radio-button>
                    <mat-radio-button value="right">Right</mat-radio-button>
                </mat-radio-group>
            </mat-form-field>

remove the parent <mat-form-field> tags

In DOS you couldn't use environment variables on the command line, only in batch files, where they used the % sign as a delimiter. If you wanted a literal % sign in a batch file, e.g. in an echo statement, you needed to double it.

This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your % signs in a .cmd file.

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

Assuming the .resx file was added using Visual Studio under the project properties, there is an easier and less error prone way to access the string.

1. Expanding the .resx file in the Solution Explorer should show a .Designer.cs file.
2. When opened, the .Designer.cs file has a Properties namespace and an internal class. For this example assume the class is named Resources.

3. Accessing the string is then as easy as:

   var resourceManager = JoshCodes.Core.Testing.Unit.Properties.Resources.ResourceManager;
   var exampleXmlString = resourceManager.GetString("exampleXml");
   

4. Replace JoshCodes.Core.Testing.Unit with the project's default namespace.

5. Replace "exampleXml" with the name of your string resource.

There might be neater methods, but the following could be one approach:

SELECT    t.fk,
          (
             SELECT t1.Field1 
             FROM   `table` t1 
             WHERE  t1.fk = t.fk AND t1.Field1 IS NOT NULL
             LIMIT  1
          ) Field1,
          (
             SELECT t2.Field2
             FROM   `table` t2 
             WHERE  t2.fk = t.fk AND t2.Field2 IS NOT NULL
             LIMIT  1
          ) Field2
FROM      `table` t
WHERE     t.fk = 3
GROUP BY  t.fk;

Test Case:

CREATE TABLE `table` (fk int, Field1 varchar(10), Field2 varchar(10));

INSERT INTO `table` VALUES (3, 'ABC', NULL);
INSERT INTO `table` VALUES (3, NULL, 'DEF');
INSERT INTO `table` VALUES (4, 'GHI', NULL);
INSERT INTO `table` VALUES (4, NULL, 'JKL');
INSERT INTO `table` VALUES (5, NULL, 'MNO');

Result:

+------+--------+--------+
| fk   | Field1 | Field2 |
+------+--------+--------+
|    3 | ABC    | DEF    |
+------+--------+--------+
1 row in set (0.01 sec)

Running the same query without the WHERE t.fk = 3 clause, it would return the following result-set:

+------+--------+--------+
| fk   | Field1 | Field2 |
+------+--------+--------+
|    3 | ABC    | DEF    |
|    4 | GHI    | JKL    |
|    5 | NULL   | MNO    |
+------+--------+--------+
3 rows in set (0.01 sec)

Here is what I would do.
Also I would use a template function to make the construction of select2nd easier.

#include <map>
#include <vector>
#include <algorithm>
#include <memory>
#include <string>

/*
 * A class to extract the second part of a pair
 */   
template<typename T>
struct select2nd
{
    typename T::second_type operator()(T const& value) const
    {return value.second;}
};

/*
 * A utility template function to make the use of select2nd easy.
 * Pass a map and it automatically creates a select2nd that utilizes the
 * value type. This works nicely as the template functions can deduce the
 * template parameters based on the function parameters. 
 */
template<typename T>
select2nd<typename T::value_type> make_select2nd(T const& m)
{
    return select2nd<typename T::value_type>();
}

int main()
{
    std::map<int,std::string>   m;
    std::vector<std::string>    v;

    /*
     * Please note: You must use std::back_inserter()
     *              As transform assumes the second range is as large as the first.
     *              Alternatively you could pre-populate the vector.
     *
     * Use make_select2nd() to make the function look nice.
     * Alternatively you could use:
     *    select2nd<std::map<int,std::string>::value_type>()
     */   
    std::transform(m.begin(),m.end(),
                   std::back_inserter(v),
                   make_select2nd(m)
                  );
}

You are tryng to send js array with js object format.

Instead of use

var a = new array();
a['something']=...

try:

var a = new Object();
a.something = ...

One idea would be to winsorize the data in a two-pass procedure:

1. run a first pass, learn what the bounds are, e.g. cut of at given percentile, or N standard deviation above the mean, or ...

2. in a second pass, set the values beyond the given bound to the value of that bound

I should stress that this is an old-fashioned method which ought to be dominated by more modern robust techniques but you still come across it a lot.

If you need support for serializing nested fields, similar to how PHP handles form fields, you can use the following function

function update(data, keys, value) {_x000D_
  if (keys.length === 0) {_x000D_
    // Leaf node_x000D_
    return value;_x000D_

_x000D_
  let key = keys.shift();_x000D_
  if (!key) {_x000D_
    data = data || [];_x000D_
    if (Array.isArray(data)) {_x000D_
      key = data.length;_x000D_
    }_x000D_
  }_x000D_
_x000D_
  // Try converting key to a numeric value_x000D_
  let index = +key;_x000D_
  if (!isNaN(index)) {_x000D_
    // We have a numeric index, make data a numeric array_x000D_
    // This will not work if this is a associative array _x000D_
    // with numeric keys_x000D_
    data = data || [];_x000D_
    key = index;_x000D_

  _x000D_

  data = data || {};_x000D_
_x000D_
  let val = update(data[key], keys, value);_x000D_
  data[key] = val;_x000D_
_x000D_
  return data;_x000D_

_x000D_
function serializeForm(form) {_x000D_
  return Array.from((new FormData(form)).entries())_x000D_
    .reduce((data, [field, value]) => {_x000D_
      let [_, prefix, keys] = field.match(/^([^\[]+)((?:\[[^\]]*\])*)/);_x000D_
_x000D_
      if (keys) {_x000D_
        keys = Array.from(keys.matchAll(/\[([^\]]*)\]/g), m => m[1]);_x000D_
        value = update(data[prefix], keys, value);_x000D_

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

Use $ne instead of $not

http://docs.mongodb.org/manual/reference/operator/ne/#op._S_ne

db.collections.find({"name": {$ne: ""}});

Below query will provide exactly the same result as given in the desired response:

db.books.aggregate([
    {
        $group: {
            _id: { addresses: "$addr", books: "$book" },
            num: { $sum :1 }
        }
    },
    {
        $group: {
            _id: "$_id.addresses",
            bookCounts: { $push: { bookName: "$_id.books",count: "$num" } }
        }
    },
    {
        $project: {
            _id: 1,
            bookCounts:1,
            "totalBookAtAddress": {
                "$sum": "$bookCounts.count"
            }
        }
    }

]) 

The response will be looking like below:

/* 1 */
{
    "_id" : "address4",
    "bookCounts" : [
        {
            "bookName" : "book3",
            "count" : 1
        }
    ],
    "totalBookAtAddress" : 1

Pressing ESC quits from insert mode to normal mode, where you can press : to type in a command. Press i again to back to insert mode, and you are good to go.

I'm not a Vim guru, so someone else can be more experienced and give you other options.

Aside from other great responses, I just had to give NTFS permissions to the Oracle installation folder. (I gave read access)

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is) 

Full source code RoadProvider.java

class MapPathScreen extends MainScreen {
    MapControl map;
    Road mRoad = new Road();
    public MapPathScreen() {
        double fromLat = 49.85, fromLon = 24.016667;
        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }
    protected void onUiEngineAttached(boolean attached) {
        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {
        HttpConnection urlConnection = null;
        InputStream is = null;
        try {
            urlConnection = (HttpConnection) Connector.open(url);
            urlConnection.setRequestMethod("GET");
            is = urlConnection.openInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return is;
    }
}

Simply check if there is a protocol (delineated by "://") and add "http://" if there isn't.

if (false === strpos($url, '://')) {
    $url = 'http://' . $url;
}

Note: This may be a simple and straightforward solution, but Jack's answer using parse_url is almost as simple and much more robust. You should probably use that one.

Tried this out quickly in the interactive shell:

>>> l = ['a', 'ab', 'abc', 'bac']
>>> [x for x in l if 'ab' in x]
['ab', 'abc']
>>>

Why does this work? Because the in operator is defined for strings to mean: "is substring of".

Also, you might want to consider writing out the loop as opposed to using the list comprehension syntax used above:

l = ['a', 'ab', 'abc', 'bac']
result = []
for s in l:
   if 'ab' in s:
       result.append(s)

I noticed one error in Dave Ward's answer (perhaps a recent change?): The query string paramaters are in request.query, not request.params. (See https://stackoverflow.com/a/6913287/166530 )

request.params by default is filled with the value of any "component matches" in routes, i.e.

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

and, if you have configured express to use its bodyparser (app.use(express.bodyParser());) also with POST'ed formdata. (See How to retrieve POST query parameters? )

Although many great answers were written to this question, none of them uses the Rspec tags approach.

I use tags to run one or more specs in different files -- only those related to my current development task.

For example, I add the tag "dev" with the value "current":

it "creates an user", dev: :current do
  user = create(:user)
  expect(user.persisted?).to be_truthy
end

then I run

bundle exec rspec . --tag dev:current

Different tags/values can be set in individual specs or groups.

The resolution is to use TypedQuery instead. When creating a query from the EntityManager instead call it like this:

TypedQuery<[YourClass]> query = entityManager.createQuery("[your sql]", [YourClass].class);
List<[YourClass]> list = query.getResultList(); //no type warning

This also works the same for named queries, native named queries, etc. The corresponding methods have the same names as the ones that would return the vanilla query. Just use this instead of a Query whenever you know the return type.

In my case,this error happen when I use the Floating action button and set android:backgroundTint="#000". Then just don't set backgroundTint and problem solved. Hope it's helpful for you.

simply add to your data structure ( mItems ) , and then notify your adapter about dataset change

private void addItem(String item) {
  mItems.add(item);
  mAdapter.notifyDataSetChanged();
}

addItem("New Item");

Use both. In fact refer a guide like the OWASP XSS Prevention cheat sheet, on the possible cases for usage of output encoding and input validation.

Input validation helps when you cannot rely on output encoding in certain cases. For instance, you're better off validating inputs appearing in URLs rather than encoding the URLs themselves (Apache will not serve a URL that is url-encoded). Or for that matter, validate inputs that appear in JavaScript expressions.

Ultimately, a simple thumb rule will help - if you do not trust user input enough or if you suspect that certain sources can result in XSS attacks despite output encoding, validate it against a whitelist.

Do take a look at the OWASP ESAPI source code on how the output encoders and input validators are written in a security library.

System environment variables are globally accessed by all users.
User environment variables are specific only to the currently logged-in user.

In Xamarin Use this

Control.SetBackgroundColor(global::Android.Graphics.Color.ParseColor("#F5F1F1"));

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

alternatively you can also do this:

p '< echo "x y"' w impulse

x and y are the coordinates of the point to which you draw a vertical bar

Right click on the code, and you have "Format Document". In my case it is Ctrl+Shift+I

For your first question try

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS); 

(available since API 8)

To access individual files in this directory use either File.list() or File.listFiles(). Seems that reporting download progress is only possible in notification, see here.

Another option is to use mongoose-history plugin.

let mongoose = require('mongoose');
let mongooseHistory = require('mongoose-history');
let Schema = mongoose.Schema;

let MySchema = Post = new Schema({
    title: String,
    status: Boolean
});

MySchema.plugin(mongooseHistory);
// The plugin will automatically create a new collection with the schema name + "_history".
// In this case, collection with name "my_schema_history" will be created.

It's even more simple using Faker.

Installation

pip install faker

Usage:

from faker import Faker
fake = Faker()

fake.date_between(start_date='today', end_date='+30y')
# datetime.date(2025, 3, 12)

fake.date_time_between(start_date='-30y', end_date='now')
# datetime.datetime(2007, 2, 28, 11, 28, 16)

# Or if you need a more specific date boundaries, provide the start 
# and end dates explicitly.
import datetime
start_date = datetime.date(year=2015, month=1, day=1)
fake.date_between(start_date=start_date, end_date='+30y')

It's very simple using radar

Installation

pip install radar

Usage

import datetime

import radar 

# Generate random datetime (parsing dates from str values)
radar.random_datetime(start='2000-05-24', stop='2013-05-24T23:59:59')

# Generate random datetime from datetime.datetime values
radar.random_datetime(
    start = datetime.datetime(year=2000, month=5, day=24),
    stop = datetime.datetime(year=2013, month=5, day=24)
)

# Just render some random datetime. If no range is given, start defaults to 
# 1970-01-01 and stop defaults to datetime.datetime.now()
radar.random_datetime()

Another option is setting the log levels for specific tags:

adb logcat SensorService:S PowerManagerService:S NfcService:S power:I Sensors:E

If you just want to set the log levels for some tags you can do it on a tag by tag basis.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

I can copy my answer from here: Easiest way to cause memory leak in Java?

"A memory leak, in computer science (or leakage, in this context), occurs when a computer program consumes memory but is unable to release it back to the operating system." (Wikipedia)

The easy answer is: You can't. Java does automatic memory management and will free resources that are not needed for you. You can't stop this from happening. It will ALWAYS be able to release the resources. In programs with manual memory management, this is different. You cann get some memory in C using malloc(). To free the memory, you need the pointer that malloc returned and call free() on it. But if you don't have the pointer anymore (overwritten, or lifetime exceeded), then you are unfortunately incapable of freeing this memory and thus you have a memory leak.

All the other answers so far are in my definition not really memory leaks. They all aim at filling the memory with pointless stuff real fast. But at any time you could still dereference the objects you created and thus freeing the memory --> NO LEAK. acconrad's answer comes pretty close though as I have to admit since his solution is effectively to just "crash" the garbage collector by forcing it in an endless loop).

The long answer is: You can get a memory leak by writing a library for Java using the JNI, which can have manual memory management and thus have memory leaks. If you call this library, your java process will leak memory. Or, you can have bugs in the JVM, so that the JVM looses memory. There are probably bugs in the JVM, there may even be some known ones since garbage collection is not that trivial, but then it's still a bug. By design this is not possible. You may be asking for some java code that is effected by such a bug. Sorry I don't know one and it might well not be a bug anymore in the next Java version anyway.

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

ID is used to uniquely identify an element.

Name is used in forms.Although you submit a form, if you dont give any name, nothing will will be submitted. Hence form elements need a name to get identified by form methods like "get or push".

And the ones only with name attribute will go out.

Instead of using the instance with the scope resolution operator :: because it wasn't defined like static function.

$r=Page::getInstanceByName($page);

change it to :

$r=Page->getInstanceByName($page);

And it will work like a charm.

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.

I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).

When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

Sometimes AutoGenerateBindingRedirects isn't enough (even with GenerateBindingRedirectsOutputType). Searching for all the There was a conflict entries and fixing them manually one by one can be tedious, so I wrote a small piece of code that parses the log output and generates them for you (dumps to stdout):

// Paste all "there was a conflict" lines from the msbuild diagnostics log to the file below
const string conflictFile = @"C:\AssemblyConflicts.txt";

var sb = new StringBuilder();
var conflictLines = await File.ReadAllLinesAsync(conflictFile);
foreach (var line in conflictLines.Where(l => !String.IsNullOrWhiteSpace(l)))
{
    Console.WriteLine("Processing line: {0}", line);

    var lineComponents = line.Split('"');
    if (lineComponents.Length < 2) 
        throw new FormatException("Unexpected conflict line component count");

    var assemblySegment = lineComponents[1];
    Console.WriteLine("Processing assembly segment: {0}", assemblySegment);
    var assemblyComponents = assemblySegment
                              .Split(",")
                              .Select(kv => kv.Trim())
                              .Select(kv => kv.Split("=")
                              .Last())
                              .ToArray();

    if (assemblyComponents.Length != 4) 
        throw new FormatException("Unexpected conflict segment component count");

    var assembly = assemblyComponents[0];
    var version = assemblyComponents[1];
    var culture = assemblyComponents[2];
    var publicKeyToken = assemblyComponents[3];

    Console.WriteLine("Generating assebmly redirect for Assembly={0}, Version={1}, Culture={2}, PublicKeyToken={3}", assembly, version, culture, publicKeyToken);
    sb.AppendLine($"<dependentAssembly><assemblyIdentity name=\"{assembly}\" publicKeyToken=\"{publicKeyToken}\" culture=\"{culture}\" /><bindingRedirect oldVersion=\"0.0.0.0-{version}\" newVersion=\"{version}\" /></dependentAssembly>");
}

Console.WriteLine("Generated assembly redirects:");
Console.WriteLine(sb);

Tip: use MSBuild Binary and Structured Log Viewer and only generate binding redirects for the conflicts in the project that emits the warning (that is, only past those there was a conflict lines to the input text file for the code above [AssemblyConflicts.txt]).

According to the API for XCUIElement .exists can be used to check if a query exists or not so the following syntax could be useful in some cases!

let app = XCUIApplication()
app.launch()

let label = app.staticTexts["Hello, world!"]
while !label.exists {
    sleep(1)
}

If you are confident that your expectation will be met eventually you could try running this. It should be noted that crashing might be preferable if the wait is too long in which case waitForExpectationsWithTimeout(_,handler:_) from @Joe Masilotti's post should be used.

Main advantage of <jsp:include /> over <%@ include > is:

<jsp:include /> allows to pass parameters

<jsp:include page="inclusion.jsp">
    <jsp:param name="menu" value="objectValue"/>
</jsp:include>

which is not possible in <%@include file="somefile.jsp" %>

I know this is an old post, but I think this is a very important topic, especially nowadays where we have 10M+ records and talk about terabytes of data.

I will also weight in with the following observations. I have about 45M records in my table ([data]), and about 300 records in my [cats] table. I have extensive indexing for all of the queries I am about to talk about.

Consider Example 1:

UPDATE d set category = c.categoryname
FROM [data] d
JOIN [cats] c on c.id = d.catid

versus Example 2:

UPDATE d set category = (SELECT TOP(1) c.categoryname FROM [cats] c where c.id = d.catid)
FROM [data] d

Example 1 took about 23 mins to run. Example 2 took around 5 mins.

So I would conclude that sub-query in this case is much faster. Of course keep in mind that I am using M.2 SSD drives capable of i/o @ 1GB/sec (thats bytes not bits), so my indexes are really fast too. So this may affect the speeds too in your circumstance

If its a one-off data cleansing, probably best to just leave it run and finish. I use TOP(10000) and see how long it takes and multiply by number of records before I hit the big query.

If you are optimizing production databases, I would strongly suggest pre-processing data, i.e. use triggers or job-broker to async update records, so that real-time access retrieves static data.

Answer above is missing an example which might not be obvious (it wasn't to me).

Url could be broken down into parts

https://github.com/liufa/Tuplinator/commit/f36e3c5b3aba23a6c9cf7c01e7485028a23c3811
                  \_____/\________/       \_______________________________________/
                   |        |                              |
            Account name    |                      Hash of revision
                        Project name              

Hash can be found here (you can click it and will get the url from browser).

Hope this saves you some time.

So all in one line:

var checkedItemsAsString = $('[id*="checkbox"]:checked').map(function() { return $(this).val().toString(); } ).get().join(",");

..a note about the selector [id*="checkbox"] , it will grab any item with the string "checkbox" in it. A bit clumsy here, but really good if you are trying to pull the selected values out of something like a .NET CheckBoxList. In that case "checkbox" would be the name that you gave the CheckBoxList control.

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

Originally posted as an edit to @0x90's answer, but it got rejected for deviating from the post's original intent and recommended to post as a comment or answer, so I'm including the short write-up here.

In addition to the answer from @0x90, the syntax can be made more flexible, by using a variable for the width (as per @user2763554's comment):

width=10
'{0: <{width}}'.format('sss', width=width)

Further, you can make this expression briefer, by only using numbers and relying on the order of the arguments passed to format:

width=10
'{0: <{1}}'.format('sss', width)

Or even leave out all numbers for maximal, potentially non-pythonically implicit, compactness:

width=10
'{: <{}}'.format('sss', width)

Update 2017-05-26

With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to access previously defined variables with a briefer syntax:

>>> name = "Fred"
>>> f"He said his name is {name}."
'He said his name is Fred.'

This also applies to string formatting

>>> width=10
>>> string = 'sss'
>>> f'{string: <{width}}'
'sss       '

If setting a fixed width on the image is not an option, here's an alternative solution.

Having a parent div with display: table & table-layout: fixed. Then setting the image to display: table-cell and max-width to 100%. That way the image will fit to the width of its parent.

Example:

<style>
    .wrapper { float: left; clear: left; display: table; table-layout: fixed; }
    img.img-responsive { display: table-cell; max-width: 100%; }
</style>
<div class="wrapper col-md-3">
    <img class="img-responsive" src="https://www.google.co.uk/images/srpr/logo11w.png"/>
</div>

If you don't have to store more than 24 hours you can just store time, since SQL Server 2008 and later the mapping is

time (SQL Server) <-> TimeSpan(.NET)

No conversions needed if you only need to store 24 hours or less.

Source: http://msdn.microsoft.com/en-us/library/cc716729(v=vs.110).aspx

But, if you want to store more than 24h, you are going to need to store it in ticks, retrieve the data and then convert to TimeSpan. For example

int timeData = yourContext.yourTable.FirstOrDefault();
TimeSpan ts = TimeSpan.FromMilliseconds(timeData);

You can with flexbox:

ul.list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    justify-items: center;
    flex-wrap: wrap;
    justify-content: center;
}
li {
    width: 100px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
    margin: 0 5px;
}

<ul class="list">
  <li>title 1</li>
  <li>title 2<br>new line</li>
  <li>title 3<br>new<br>line</li>
</ul>

In Angular 8, ViewChild always takes 2 param, and second params always has static: true or static: false

You can try like this:

@ViewChild('nameInput', {static: false}) component

Also,the static: false is going to be the default fallback behaviour in Angular 9.

What are static false/true: So as a rule of thumb you can go for the following:

• { static: true } needs to be set when you want to access the ViewChild in ngOnInit.

  { static: false } can only be accessed in ngAfterViewInit. This is also what you want to go for when you have a structural directive (i.e. *ngIf) on your element in your template.

To expand on the answer provided by @Orion Edwards, this is how you would do fully from code-behind (no styles set). Basically create a custom class that inherits from Border which has its Child set to a TextBox. The example below assumes that you only want a single line and that the border is a child of a Canvas. Also assumes you would need to adjust the MaxLength property of the TextBox based on the width of the Border. The example below also sets the cursor of the Border to mimic a Textbox by setting it to the type 'IBeam'. A margin of '3' is set so that the TextBox isn't absolutely aligned to the left of the border.

double __dY = 180;

Found a nice hack on codepen that modifies the opacity property but achieves that fade from one gradient to another by leveraging pseudo-elements. What he does is he sets an :after so that when you change the opacity of the actual element, the :after element shows up so it looks as if it were a fade. Thought it'd be useful to share.

Simply, this should do the task:

import pandas as pd

grouped_df = df1.groupby( [ "Name", "City"] )

pd.DataFrame(grouped_df.size().reset_index(name = "Group_Count"))

Here, grouped_df.size() pulls up the unique groupby count, and reset_index() method resets the name of the column you want it to be. Finally, the pandas Dataframe() function is called upon to create a DataFrame object.

declare @n int = 7,
    @m int = 3;

select 
    case 
        when @n = 1 then
            'SOMETEXT'
    else
        case 
            when @m = 1 then
                'SOMEOTHERTEXT'
            when @m = 2 then
                'SOMEOTHERTEXTGOESHERE'
        end
    end as col1
-- n=1 => returns SOMETEXT regardless of @m
-- n=2 and m=1 => returns SOMEOTHERTEXT
-- n=2 and m=2 => returns SOMEOTHERTEXTGOESHERE
-- n=2 and m>2 => returns null (no else defined for inner case)

Step 1: Create a filter component by implementing Filter interface.

@Component
public class PerformanceFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

            ......
            ......
    }

}

Step 2: Set this filter to the uri patterns using FilterRegistrationBean.

@Configuration
public class FilterConfig {
    @Bean
    public FilterRegistrationBean<PerformanceFilter> perfFilter() {
        FilterRegistrationBean<PerformanceFilter> registration = new FilterRegistrationBean<>();
        registration.setFilter(new PerformanceFilter());
        registration.addUrlPatterns("/*");
        return registration;
    }
}

It's necessary because, more or less, when we import a project from git, it's not a maven project, so the maven dependencies are not in the build path.

Here's what I have done to turn a general project to a maven project.

general project-->java project right click the project, properties->project facets, click "java". This step will turn a general project into java project.

java project --> maven project right click project, configure-->convert to maven project At this moment, maven dependencies lib are still not in the build path. project properties, build path, add library, add maven dependencies lib

And wait a few seconds, when the dependencies are loaded, the project is ready!

I took the following approach, which uses a simple modal progress indicator widget that wraps whatever you want to make modal during an async call.

The example in the package also addresses how to handle form validation while making async calls to validate the form (see flutter/issues/9688 for details of this problem). For example, without leaving the form, this async form validation method can be used to validate a new user name against existing names in a database while signing up.

https://pub.dartlang.org/packages/modal_progress_hud

Here is the demo of the example provided with the package (with source code):

Example could be adapted to other modal progress indicator behaviour (like different animations, additional text in modal, etc..).

Using pstools - in particular psservice and "query" - for example:

psservice query "serviceName"

As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:

Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}

From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.

This along with @BlackHawkDesign comment should help you find what you need.

I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00

You can use as below:

string selected = cmbbox.Text;
MessageBox.Show(selected);

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

Try this :

$('#form1').submit();

or

document.form1.submit();

You can use this program instead of sprintf.

void itochar(int x, char *buffer, int radix);

int main()
{
    char buffer[10];
    itochar(725, buffer, 10);
    printf ("\n %s \n", buffer);
    return 0;
}

void itochar(int x, char *buffer, int radix)
{
    int i = 0 , n,s;
    n = s;
    while (n > 0)
    {
        s = n%radix;
        n = n/radix;
        buffer[i++] = '0' + s;
    }
    buffer[i] = '\0';
    strrev(buffer);
}

You can parse the pom file with JDOM (http://www.jdom.org/).

Try this

// Create a DecimalFormat that fits your requirements
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator(',');
symbols.setDecimalSeparator('.');
String pattern = "#,##0.0#";
DecimalFormat decimalFormat = new DecimalFormat(pattern, symbols);
decimalFormat.setParseBigDecimal(true);

// parse the string
BigDecimal bigDecimal = (BigDecimal) decimalFormat.parse("10,692,467,440,017.120");
System.out.println(bigDecimal);

If you are building an application with I18N support you should use DecimalFormatSymbols(Locale)

Also keep in mind that decimalFormat.parse can throw a ParseException so you need to handle it (with try/catch) or throw it and let another part of your program handle it

If your application is making heavy use of Date and Calendar objects, you really should use Joda Time, because java.util.Date is mutable. java.util.Calendar has performance problems when its fields get updated, and is clunky for datetime arithmetic.

It means not equal to, as the others said..

I just wanted to say that I read that as "greater than or lesser than".

e.g.

let x = 12

if x <> 0 then
    //code

In this case 'x' is greater than (that's the '>' symbol) 0.

Hope this helps. :D

I didn't find TextView scrolling to support the 'fling' gesture, where it continues scrolling after a flick up or down. I ended up implementing that myself because I didn't want to use a ScrollView for various reasons, and there didn't seem to be a MovementMethod that both allowed me to select text and click on links.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

Sadly the other posters are correct that you're ...actually as corrected by kRON, you are ok with your IE7 and a strict doc, but most of us with IE6 requirements are reduced to JS or class references for this, but it is a CSS2 property, just one without sufficient support from IE^h^h browsers.

Out of completeness, the type selector is - similar to xpath - of the form [attribute=value] but many interesting variants exist. It will be quite powerful when it's available, good thing to keep in your head for IE8.

The latest version of firefox the firefox 57(Quantum) supports date and other features it was released on November 14, 2017. You can download it by clicking this link

The proper solution to resolve this issue is by following the steps

. Update Visual studio if you have older version to 15.5.4 (Optional)

2. Remove all binding redirects from web.config

3. Add this to the csproj file:

 <PropertyGroup>
  <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
  <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>

4. Build.

5. In the bin folder, there should be a (WebAppName).dll.config file.

6. It should have redirects in it. Copy these to the web.config

7. Remove the above snipped from the csproj file again

8. It should work

I had the same error and I had not made any changes to the application config or the web.xml. Multiple tries to revert back some minor changes to code was not clearing the exceptions. Finally it worked after restarting STS.

I am not sure what the problem is, but I am pretty sure this will fix it.

Ok, i've been here a few times and not entirely sure how or why this happens but reading suggests its a Kotlin/JVM mismatch. I have tried a number of things mentioned on this page but not without complete success. This was the sort of symptom the IDE was displaying in the message panel after trying to run tests via the IDE. However the code panel has no red lines indicating that modules can't be found or imported or anything untoward.

My project (at time of writing this) is a gradle 4.10.2 kotlin 1.3 project in IntelliJ (IntelliJ IDEA 2018.2.5 (Ultimate Edition) Build #IU-182.4892.20, built on October 16, 2018)

For starters though, I invalidated caches and restarted. Then ran a gradle clean build. After rebuilding the project still no joy. I went into the project settings and noticed the compiler versions were not set to java 8, I set the Compiler/Kotlin/Target JVM Version and Compiler/Java/Project Byte Code to 1.8/8 (see below), then ran some tests in the IDE and we are back in business! References resolved in my case.

Demo

css

div {
    width: 100px;
    height: 100px;
    border-radius: 50%;
    background: red;
}

html

<div></div>

Use the setAttribute method:

document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");

But you really should be using data followed with a dash and with its property, like:

<li ... data-icon="base.gif" ...>

And to do it in JS use the dataset property:

document.getElementById('item1').dataset.icon = "base.gif";

You have mixed indentation formatting (spaces and tabs)

On Notepad++

Change Tab Settings to 4 spaces

Go to Settings -> Preferences -> Tab Settings -> Replace by spaces

Fix the current file mixed indentations

Select everything CTRL+A

Click TAB once, to add an indentation everywhere

Run SHIFT + TAB to remove the extra indentation, it will replace all TAB characters to 4 spaces.

For functional components with hooks

const [searches, setSearches] = useState([]);

// Using .concat(), no wrapper function (not recommended)
setSearches(searches.concat(query));

// Using .concat(), wrapper function (recommended)
setSearches(searches => searches.concat(query));

// Spread operator, no wrapper function (not recommended)
setSearches([...searches, query]);

// Spread operator, wrapper function (recommended)
setSearches(searches => [...searches, query]);

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.

For your purpose, you probably want something like:

FOR %i IN (*.ext) DO my-function %i

Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).

The (*.ext) part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:

FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i

To perform an operation in a different directory.

There are scores of options for the filespec and FOR in general. See

HELP FOR

from the command prompt for more information.

For Python 3 you will need to import import urllib.request:

import urllib.request 

urllib.request.urlretrieve(url, filename)

Use public_path()

For reference:

// Path to the project's root folder    
echo base_path();

// Path to the 'app' folder    
echo app_path();        

// Path to the 'public' folder    
echo public_path();

// Path to the 'storage' folder    
echo storage_path();

// Path to the 'storage/app' folder    
echo storage_path('app');

The Web API basically return 4 type of object: void, HttpResponseMessage, IHttpActionResult, and other strong types. The first version of the Web API returns HttpResponseMessage which is pretty straight forward HTTP response message.

The IHttpActionResult was introduced by WebAPI 2 which is a kind of wrap of HttpResponseMessage. It contains the ExecuteAsync() method to create an HttpResponseMessage. It simplifies unit testing of your controller.

Other return type are kind of strong typed classes serialized by the Web API using a media formatter into the response body. The drawback was you cannot directly return an error code such as a 404. All you can do is throwing an HttpResponseException error.
