It can be complicated to compute a diff in your head from the different sections in $MERGED and apply that. In my setup, meld helps by showing you these diffs visually, using:

[merge]
    tool = mymeld
    conflictstyle = diff3

[mergetool "mymeld"]
    cmd = meld --diff $BASE $REMOTE --diff $REMOTE $LOCAL --diff $LOCAL $MERGED

It looks strange but offers a very convenient work-flow, using three tabs:

1. in tab 1 you see (from left to right) the change that you should make in tab 2 to solve the merge conflict.

2. in the right side of tab 2 you apply the "change that you should make" and copy the entire file contents to the clipboard (using ctrl-a and ctrl-c).

3. in tab 3 replace the right side with the clipboard contents. If everything is correct, you will now see - from left to right - the same change as shown in tab 1 (but with different contexts). Save the changes made in this tab.

Notes:

• don't edit anything in tab 1
• don't save anything in tab 2 because that will produce annoying popups in tab 3

If you encode the & in your URL to %26 it works correctly. Just tested and verified.

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

well bubble sort is better than insertion sort only when someone is looking for top k elements from a large list of number i.e. in bubble sort after k iterations you'll get top k elements. However after k iterations in insertion sort, it only assures that those k elements are sorted.

• Official Python .msi installers are designed to replace:

  • any previous micro release (in x.y.z, z is "micro") because they are guaranteed to be backward-compatible and binary-compatible
  • a "snapshot" (built from source) installation with any micro version

• A snapshot installer is designed to replace any snapshot with a lower micro version.

(See responsible code for 2.x, for 3.x)

Any other versions are not necessarily compatible and are thus installed alongside the existing one. If you wish to uninstall the old version, you'll need to do that manually. And also uninstall any 3rd-party modules you had for it:

• If you installed any modules from bdist_wininst packages (Windows .exes), uninstall them before uninstalling the version, or the uninstaller might not work correctly if it has custom logic
• modules installed with setuptools/pip that reside in Lib\site-packages can just be deleted afterwards
• packages that you installed per-user, if any, reside in %APPDATA%/Python/PythonXY/site-packages and can likewise be deleted

hi here is a simple example: <div id="test">content</div> and

var test = 5;
document.getElementById('test').innerHTML = test;

and you can test it here : http://jsfiddle.net/SLbKX/

Try defining a new class, ulheader, in css. p.ulheader ~ ul selects all that immediately follows My Header

p.ulheader ~ ul {
   margin-top:0;
{
p.ulheader {
   margin-bottom;0;
}

Just make a new class like this:

public class SortedList<T> extends ArrayList<T> {

private final Comparator<? super T> comparator;

public SortedList() {
    super();
    this.comparator = null;
}

public SortedList(Comparator<T> comparator) {
    super();
    this.comparator = comparator;
}

@Override
public boolean add(T item) {
    int index = comparator == null ? Collections.binarySearch((List<? extends Comparable<? super T>>)this, item) :
            Collections.binarySearch(this, item, comparator);
    if (index < 0) {
        index = index * -1 - 2;
    }
    super.add(index+1, item);
    return true;
}

@Override
public void add(int index, T item) {
    throw new UnsupportedOperationException("'add' with an index is not supported in SortedArrayList");
}

@Override
public boolean addAll(Collection<? extends T> items) {
    boolean allAdded = true;
    for (T item : items) {
        allAdded = allAdded && add(item);
    }
    return allAdded;
}

@Override
public boolean addAll(int index, Collection<? extends T> items) {
    throw new UnsupportedOperationException("'addAll' with an index is not supported in SortedArrayList");
}

}

You can test it like this:

    List<Integer> list = new SortedArrayList<>((Integer i1, Integer i2) -> i1.compareTo(i2));
    for (Integer i : Arrays.asList(4, 7, 3, 8, 9, 25, 20, 23, 52, 3)) {
        list.add(i);
    }
    System.out.println(list);

I think but I am not sure : the for loop takes two operations for checking and incrementing values. foreach loads the data in memory then it will iterate every values.

Here is my understanding of it so far, in case it helps someone.

core.autocrlf=true and core.safecrlf = true

You have a repository where all the line endings are the same, but you work on different platforms. Git will make sure your lines endings are converted to the default for your platform. Why does this matter? Let's say you create a new file. The text editor on your platform will use its default line endings. When you check it in, if you don't have core.autocrlf set to true, you've introduced a line ending inconsistency for someone on a platform that defaults to a different line ending. I always set safecrlf too because I would like to know that the crlf operation is reversible. With these two settings, git is modifying your files, but it verifies that the modifications are reversible.

core.autocrlf=false

You have a repository that already has mixed line endings checked in and fixing the incorrect line endings could break other things. Its best not to tell git to convert line endings in this case, because then it will exacerbate the problem it was designed to solve - making diffs easier to read and merges less painful. With this setting, git doesn't modify your files.

core.autocrlf=input

I don't use this because the reason for this is to cover a use case where you created a file that has CRLF line endings on a platform that defaults to LF line endings. I prefer instead to make my text editor always save new files with the platform's line ending defaults.

I’m reposting my answer to a similar question because no-one seems to have given it here and it’s much cleaner and neater:

Use the alternative buttons property syntax:

$dialogDiv.dialog({
    autoOpen: false,
    modal: true,
    width: 600,
    resizable: false,
    buttons: [
        {
            text: "Cancel",
            "class": 'cancelButtonClass',
            click: function() {
                // Cancel code here
            }
        },
        {
            text: "Save",
            "class": 'saveButtonClass',
            click: function() {
                // Save code here
            }
        }
    ],
    close: function() {
        // Close code here (incidentally, same as Cancel code)
    }
});

Here is a shorter, cleaner way to get the IP address:

function get_ip_address(){
    foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
        if (array_key_exists($key, $_SERVER) === true){
            foreach (explode(',', $_SERVER[$key]) as $ip){
                $ip = trim($ip); // just to be safe

                if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                    return $ip;
                }
            }
        }
    }
}

Your code seems to be pretty complete already, I cannot see any possible bugs in it (aside from the usual IP caveats), I would change the validate_ip() function to rely on the filter extension though:

public function validate_ip($ip)
{
    if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) === false)
    {
        return false;
    }

    self::$ip = sprintf('%u', ip2long($ip)); // you seem to want this

    return true;
}

Also your HTTP_X_FORWARDED_FOR snippet can be simplified from this:

// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    // check if multiple ips exist in var
    if (strpos($_SERVER['HTTP_X_FORWARDED_FOR'], ',') !== false)
    {
        $iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        
        foreach ($iplist as $ip)
        {
            if ($this->validate_ip($ip))
                return $ip;
        }
    }
    
    else
    {
        if ($this->validate_ip($_SERVER['HTTP_X_FORWARDED_FOR']))
            return $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
}

To this:

// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    $iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        
    foreach ($iplist as $ip)
    {
        if ($this->validate_ip($ip))
            return $ip;
    }
}

You may also want to validate IPv6 addresses.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library.

The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

The CertUtil is a pre-installed Windows utility, that can be used to generate hash checksums:

CertUtil -hashfile pathToFileToCheck [HashAlgorithm]

HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

So for example, the following generates an MD5 checksum for the file C:\TEMP\MyDataFile.img:

CertUtil -hashfile C:\TEMP\MyDataFile.img MD5

To get output similar to *Nix systems you can add some PS magic:

$(CertUtil -hashfile C:\TEMP\MyDataFile.img MD5)[1] -replace " ",""

The formal parameters for a function are listed in the function declaration and are used in the body of the function definition. A formal parameter (of any sort) is a kind of blank or placeholder that is filled in with something when the function is called.

An argument is something that is used to fill in a formal parameter. When you write down a function call, the arguments are listed in parentheses after the function name. When the function call is executed, the arguments are plugged in for the formal parameters.

The terms call-by-value and call-by-reference refer to the mechanism that is used in the plugging-in process. In the call-by-value method only the value of the argument is used. In this call-by-value mechanism, the formal parameter is a local variable that is initialized to the value of the corresponding argument. In the call-by-reference mechanism the argument is a variable and the entire variable is used. In the call- by-reference mechanism the argument variable is substituted for the formal parameter so that any change that is made to the formal parameter is actually made to the argument variable.

My perspective would be try/catch blocks are necessary to insure proper exception handling, but creating such blocks has performance implications. Since, Loops contain intensive repetitive computations, it is not recommended to put try/catch blocks inside loops. Additionally, it seems where this condition occurs, it is often "Exception" or "RuntimeException" which is caught. RuntimeException being caught in code should be avoided. Again, if if you work in a big company it's essential to log that exception properly, or stop runtime exception to happen. Whole point of this description is PLEASE AVOID USING TRY-CATCH BLOCKS IN LOOPS

There is indeed no such thing as a forward declaration of enum. As an enum's definition doesn't contain any code that could depend on other code using the enum, it's usually not a problem to define the enum completely when you're first declaring it.

If the only use of your enum is by private member functions, you can implement encapsulation by having the enum itself as a private member of that class. The enum still has to be fully defined at the point of declaration, that is, within the class definition. However, this is not a bigger problem as declaring private member functions there, and is not a worse exposal of implementation internals than that.

If you need a deeper degree of concealment for your implementation details, you can break it into an abstract interface, only consisting of pure virtual functions, and a concrete, completely concealed, class implementing (inheriting) the interface. Creation of class instances can be handled by a factory or a static member function of the interface. That way, even the real class name, let alone its private functions, won't be exposed.

The module approach works well. If I absolutely need a singleton I prefer the Metaclass approach.

class Singleton(type):
    def __init__(cls, name, bases, dict):
        super(Singleton, cls).__init__(name, bases, dict)
        cls.instance = None 

    def __call__(cls,*args,**kw):
        if cls.instance is None:
            cls.instance = super(Singleton, cls).__call__(*args, **kw)
        return cls.instance

class MyClass(object):
    __metaclass__ = Singleton

I guess you could try

table tr td { color: red; }
table tr td table tr td { color: black; }

Or

body table tr td { color: red; }

where 'body' is a selector for your table's parent

But classes are most likely the right way to go here.

<a href="javascript:void(0)" class="aaf" id="users_id">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
  var usersid =  $(this).attr("id");
  //post code
})

//other method is to use the data attribute

<a href="javascript:void(0)" class="aaf" data-id="102" data-username="sample_username">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
    var usersid =  $(this).data("id");
    var username = $(this).data("username");
})

What about just

xxx >& /dev/stdout

???

You can use momentjs it is very helpful you can achieve a lot of things with this library.

Get yesterday date with current timing moment().subtract(1, 'days').toString()

Get yesterday date with a start of the date moment().subtract(1, 'days').startOf('day').toString()

With Jquery:

$(".cancel-button").click(function (e) {
  e.preventDefault();
});

There is a condition that most of these solutions do not address. I revised Patrick Honorez's solution to handle it. I felt I had to share this because I was pulling my hair out when the original function was occasionally clearing more data that I expected.

The situation happens when the table only has one column and the .SpecialCells(xlCellTypeConstants).ClearContents attempts to clear the contents of the top row. In this situation, only one cell is selected (the top row of the table that only has one column) and the SpecialCells command applies to the entire sheet instead of the selected range. What was happening to me was other cells on the sheet that were outside of my table were also getting cleared.

I did some digging and found this advice from Mathieu Guindon: Range SpecialCells ClearContents clears whole sheet

Range({any single cell}).SpecialCells({whatever}) seems to work off the entire sheet.

Range({more than one cell}).SpecialCells({whatever}) seems to work off the specified cells.

If the list/table only has one column (in row 1), this revision will check to see if the cell has a formula and if not, it will only clear the contents of that one cell.

IMHO, a very nice solution is to use c++11 emplace_back function:

revenue.emplace_back("string", map[i].second);

It just creates a new element in place.

You can have multiple CTEs in one query, as well as reuse a CTE:

WITH    cte1 AS
        (
        SELECT  1 AS id
        ),
        cte2 AS
        (
        SELECT  2 AS id
        )
SELECT  *
FROM    cte1
UNION ALL
SELECT  *
FROM    cte2
UNION ALL
SELECT  *
FROM    cte1

Note, however, that SQL Server may reevaluate the CTE each time it is accessed, so if you are using values like RAND(), NEWID() etc., they may change between the CTE calls.

select column1..... from table1
where column1=''
union
select column1..... from table2
where column1= ''

<input type="text" value="A new value" onfocus="javascript: if(this.value == 'A new value'){ this.value = ''; }" onblur="javascript: if(this.value==''){this.value='A new value';}" />

It seems that in lollipop and up (or maybe just a different WebView Version) that calling cprcrack's onHideCustomView() method does not work. It works if it is called from the exit fullscreen button but when you specifically call the method it will only exit fullscreen but the webView stays blank. A way around it is to simply add these lines of code to onHideCustomView():

String js = "javascript:";
js += "var _ytrp_html5_video = document.getElementsByTagName('video')[0];";
js += "_ytrp_html5_video.webkitExitFullscreen();";
webView.loadUrl(js);

This will notify the webView that fullscreen has exited.

I've had the same problem for a long time. What I recently chose is the following directory structure:

project_path
+-- Makefile
+-- src
¦   +-- script_1.py
¦   +-- script_2.py
¦   +-- script_3.py
+-- tests
    +-- __init__.py
    +-- test_script_1.py
    +-- test_script_2.py
    +-- test_script_3.py

and in the __init__.py script of the test folder, I write the following:

import os
import sys
PROJECT_PATH = os.getcwd()
SOURCE_PATH = os.path.join(
    PROJECT_PATH,"src"
)
sys.path.append(SOURCE_PATH)

Super important for sharing the project is the Makefile, because it enforces running the scripts properly. Here is the command that I put in the Makefile:

run_tests:
    python -m unittest discover .

The Makefile is important not just because of the command it runs but also because of where it runs it from. If you would cd in tests and do python -m unittest discover ., it wouldn't work because the init script in unit_tests calls os.getcwd(), which would then point to the incorrect absolute path (that would be appended to sys.path and you would be missing your source folder). The scripts would run since discover finds all the tests, but they wouldn't run properly. So the Makefile is there to avoid having to remember this issue.

I really like this approach because I don't have to touch my src folder, my unit tests or my environment variables and everything runs smoothly.

Let me know if you guys like it.

Hope that helps,

A ClusterIP exposes the following:

• spec.clusterIp:spec.ports[*].port

You can only access this service while inside the cluster. It is accessible from its spec.clusterIp port. If a spec.ports[*].targetPort is set it will route from the port to the targetPort. The CLUSTER-IP you get when calling kubectl get services is the IP assigned to this service within the cluster internally.

A NodePort exposes the following:

• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

If you access this service on a nodePort from the node's external IP, it will route the request to spec.clusterIp:spec.ports[*].port, which will in turn route it to your spec.ports[*].targetPort, if set. This service can also be accessed in the same way as ClusterIP.

Your NodeIPs are the external IP addresses of the nodes. You cannot access your service from spec.clusterIp:spec.ports[*].nodePort.

A LoadBalancer exposes the following:

• spec.loadBalancerIp:spec.ports[*].port
• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

You can access this service from your load balancer's IP address, which routes your request to a nodePort, which in turn routes the request to the clusterIP port. You can access this service as you would a NodePort or a ClusterIP service as well.

.v-center {

  top: 50%;
  -webkit-transform: translateY(-50%);
      -ms-transform: translateY(-50%);
          transform: translateY(-50%);
}

Example: http://jsbin.com/rehovixufe/1/

 .outer {
   display: flex;
   align-items: center; 
   justify-content: center;
 }

You could use GROUP_CONCAT aggregated function to get all years into a single column, grouped by id and ordered by rate:

SELECT   id, GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
FROM     yourtable
GROUP BY id

Result:

-----------------------------------------------------------
|  ID | GROUPED_YEAR                                      |
-----------------------------------------------------------
| p01 | 2006,2003,2008,2001,2007,2009,2002,2004,2005,2000 |
| p02 | 2001,2004,2002,2003,2000,2006,2007                |
-----------------------------------------------------------

And then you could use FIND_IN_SET, that returns the position of the first argument inside the second one, eg.

SELECT FIND_IN_SET('2006', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
1

SELECT FIND_IN_SET('2009', '2006,2003,2008,2001,2007,2009,2002,2004,2005,2000');
6

Using a combination of GROUP_CONCAT and FIND_IN_SET, and filtering by the position returned by find_in_set, you could then use this query that returns only the first 5 years for every id:

SELECT
  yourtable.*
FROM
  yourtable INNER JOIN (
    SELECT
      id,
      GROUP_CONCAT(year ORDER BY rate DESC) grouped_year
    FROM
      yourtable
    GROUP BY id) group_max
  ON yourtable.id = group_max.id
     AND FIND_IN_SET(year, grouped_year) BETWEEN 1 AND 5
ORDER BY
  yourtable.id, yourtable.year DESC;

Please see fiddle here.

Please note that if more than one row can have the same rate, you should consider using GROUP_CONCAT(DISTINCT rate ORDER BY rate) on the rate column instead of the year column.

The maximum length of the string returned by GROUP_CONCAT is limited, so this works well if you need to select a few records for every group.

If you don't have a company, leave your name, it doesn't matter as long as both bundle id in info.plist file and the one you've submitted in iTunes Connect match.

In Bundle ID Suffix you should write full name of bundle ID.

Example:

Bundle ID suffix = thebestapp (NOT CORRECT!!!!)

Bundle ID suffix = com.awesomeapps.thebestapp (CORRECT!!)

The reason for this is explained in the Developer Portal:

The App ID string contains two parts separated by a period (.) — an App ID Prefix (your Team ID by default, e.g. ABCDE12345), and an App ID Suffix (a Bundle ID search string, e.g. com.mycompany.appname). [emphasis added]

So in this case the suffix is the full string com.awesomeapps.thebestapp.

The first part:

.Cells(.Rows.Count,"A")

Sends you to the bottom row of column A, which you knew already.

The End function starts at a cell and then, depending on the direction you tell it, goes that direction until it reaches the edge of a group of cells that have text. Meaning, if you have text in cells C4:E4 and you type:

Sheet1.Cells(4,"C").End(xlToRight).Select

The program will select E4, the rightmost cell with text in it.

In your case, the code is spitting out the row of the very last cell with text in it in column A. Does that help?

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));

Simple alert with array data:

NSString *name = [[YourArray objectAtIndex:indexPath.row ]valueForKey:@"Name"];

NSString *msg = [[YourArray objectAtIndex:indexPath.row ]valueForKey:@"message"];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:name
                                                message:msg
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
[alert show];

Installing bzip2 and zip PHP extensions solved my issue in Ubuntu:

sudo apt-get install php7.0-bz2
sudo apt-get install php7.0-zip

Use php(you version)-(extension) to install and enable any missing modules that is required in the phpmyadmin readme.

In order to replace text using regular expression use the re.sub function:

sub(pattern, repl, string[, count, flags])

It will replace non-everlaping instances of pattern by the text passed as string. If you need to analyze the match to extract information about specific group captures, for instance, you can pass a function to the string argument. more info here.

Examples

>>> import re
>>> re.sub(r'a', 'b', 'banana')
'bbnbnb'

>>> re.sub(r'/\d+', '/{id}', '/andre/23/abobora/43435')
'/andre/{id}/abobora/{id}'

ID's have the functionality to work as links to particular sections within a webpage. a keyword after # tag will take you to a particular section of the webpage. e.g "http://exampleurl.com#chapter5" in the address bar will take you there when you have a "section5" id wrapped around the chapter 5 section of the page.

The most important thing to remember, when you get a NULL result from JSON data that is valid is to use the following command:

json_last_error_msg();

Ie.

var_dump(json_last_error_msg());
string(53) "Control character error, possibly incorrectly encoded"

You then fix that with:

$new_json = preg_replace('/[[:cntrl:]]/', '', $json);

I'm not sure what jQuery api you're looking at, but you should only have to specify id.

$('#thumb').removeAttr('id');

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

On Windows 7 , the only thing that worked for me is this. Go to Device Manager -> Under Android Phone -> Right Click and select 'enable'

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

import pandas as pd
import wmi
from re import escape
import os

def kill_process(kill_path, execs):
    f = wmi.WMI()
    esc = escape(kill_path)
    temp = {'id':[], 'path':[], 'name':[]}
    for process in f.Win32_Process():
        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

With the sqldf package, R is capable of not only statistics, but serious data mining as well - assuming there is enough RAM on your machine.

And with the RServe package R becomes a regular TCP/IP server; so you can call R out of java (or any other language if you have the api). There is also a package in R to call java out or R.

Have you tried loading the socket.io script not from a relative URL?

You're using:

<script src="socket.io/socket.io.js"></script>

And:

socket.connect('http://127.0.0.1:8080');

You should try:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

And:

socket.connect('http://localhost:8080');

Switch localhost:8080 with whatever fits your current setup.

Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).

The string you are returning is not valid JSON. The names in the objects needs to be quoted and the whole string needs to be put in { … } to form an object. JSON also cannot contain something like new Date(). JSON is just a small subset of JavaScript that has only strings, numbers, objects, arrays, true, false and null.

See the JSON grammar for more information.

This has a more elegant explanation and more than one possible solutions. http://kasunh.wordpress.com/2011/10/11/preserving-remote-iphost-while-proxying/

The compiler is confused by the function signature. You can fix it like this:

let task = URLSession.shared.dataTask(with: request as URLRequest) {

But, note that we don't have to cast "request" as URLRequest in this signature if it was declared earlier as URLRequest instead of NSMutableURLRequest:

var request = URLRequest(url:myUrl!)

This is the automatic casting between NSMutableURLRequest and the new URLRequest that is failing and which forced us to do this casting here.

The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.

You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:

1. move the typing head back to the left. In practice in a typewriter this is done by moving the roll which carries the paper (the "carriage") all the way back to the right -- the typing head is fixed. This is a carriage return.
2. move the paper up by the width of one line. This is a line feed.

In computers, these two actions are represented by two different characters - carriage return is CR, ASCII character 13, vbCr; line feed is LF, ASCII character 10, vbLf. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF -- to start a new line, and so the CRLF combination -- vbCrLf -- became a traditional line ending sequence, in some computing environments.

The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF alone (used in Unix and Macintoshes), CR alone (apparently used in older Mac OSes) and the CRLF combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode, where any CRLF pair read from the file was converted to a single CR (and vice versa when writing).

So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine which means someone else has decided for you which to use, and future portability issues should be reduced.

What about using something like:

<?php 
    $page_title = "Your page tile";
    include("navigation.php");             // if required
    echo("<title>$page_title</title>");
?>

My full example is here, but I will provide a summary below.

Layout

Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).

Make the swift file the xib file's owner.

Code

Add the following code to the .swift file and hook up the outlets and actions from the .xib file.

import UIKit
class ResuableCustomView: UIView {

    let nibName = "ReusableCustomView"
    var contentView: UIView?

    @IBOutlet weak var label: UILabel!
    @IBAction func buttonTap(_ sender: UIButton) {
        label.text = "Hi"
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        guard let view = loadViewFromNib() else { return }
        view.frame = self.bounds
        self.addSubview(view)
        contentView = view
    }

    func loadViewFromNib() -> UIView? {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: nibName, bundle: bundle)
        return nib.instantiate(withOwner: self, options: nil).first as? UIView
    }
}

Use it

Use your custom view anywhere in your storyboard. Just add a UIView and set the class name to your custom class name.

For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.

1. Create a custom UIView class in a .swift file to control your xib. i.e. MyCustomClass.swift
2. Create a .xib file and style it as you want. i.e. MyCustomClass.xib
3. Set the File's Owner of the .xib file to be your custom class (MyCustomClass)
4. GOTCHA: leave the class value (under the identity Inspector) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.
5. Hook up your outlets as you normally would using the Assistant Editor.
   • NOTE: If you look at the Connections Inspector you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass), but rather reference File's Owner. Since File's Owner is specified to be your custom class, the outlets will hook up and work propery.
6. Make sure your custom class has @IBDesignable before the class statement.
7. Make your custom class conform to the NibLoadable protocol referenced below.
   • NOTE: If your custom class .swift file name is different from your .xib file name, then set the nibName property to be the name of your .xib file.
8. Implement required init?(coder aDecoder: NSCoder) and override init(frame: CGRect) to call setupFromNib() like the example below.
9. Add a UIView to your desired storyboard and set the class to be your custom class name (i.e. MyCustomClass).
10. Watch IBDesignable in action as it draws your .xib in the storyboard with all of it's awe and wonder.

Here is the protocol you will want to reference:

public protocol NibLoadable {
    static var nibName: String { get }
}

public extension NibLoadable where Self: UIView {

    public static var nibName: String {
        return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
    }

    public static var nib: UINib {
        let bundle = Bundle(for: Self.self)
        return UINib(nibName: Self.nibName, bundle: bundle)
    }

    func setupFromNib() {
        guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
        addSubview(view)
        view.translatesAutoresizingMaskIntoConstraints = false
        view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
        view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
        view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
        view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
    }
}

And here is an example of MyCustomClass that implements the protocol (with the .xib file being named MyCustomClass.xib):

@IBDesignable
class MyCustomClass: UIView, NibLoadable {

    @IBOutlet weak var myLabel: UILabel!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupFromNib()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupFromNib()
    }

}

NOTE: If you miss the Gotcha and set the class value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder) method which then calls Self.nib.instantiate and calls the init again.

This example shows you how to fill column B based on the the volume of data in Column A. Adjust "A1" accordingly to your needs. It will fill in column B based on the formula in B1.

Range("A1").Select
Selection.End(xlDown).Select
ActiveCell.Offset(0, 1).Select
Range(Selection, Selection.End(xlUp)).Select
Selection.FillDown

I thought I'd put my 2 cents to this discussion, even if it's rather old one.. This query returns scalar 1 if the table exists and 0 otherwise.

select 
    case when exists 
        (select 1 from sqlite_master WHERE type='table' and name = 'your_table') 
        then 1 
        else 0 
    end as TableExists

Use DATE_FORMAT()

SELECT
  DATE_FORMAT(NOW(), '%d %m %Y') AS your_date;

Seems to me like you are updating the value of the text field in javascript. onchange event will be triggered only when you key-in data and tab out of the text field.

One workaround is to trigger the textbox change event when modifying the textbox value from the script. See below,

$("#kat").change(function(){ 
    alert("Hello");
});


$('<tab_cell>').click (function () {
   $('#kat')
      .val($(this).text()) //updating the value of the textbox 
      .change();           //trigger change event.
});

In my case it was enough to change relation from:

@OneToMany(mappedBy = "county")
private List<Town> towns;

to:

@OneToMany
private List<Town> towns;

another relation stayed as it was:

@ManyToOne
@JoinColumn(name = "county_id")
private County county;

I am using this Temporary Solution:

import {Pipe, PipeTransform} from "angular2/core";
import {DateFormatter} from 'angular2/src/facade/intl';

@Pipe({
    name: 'dateFormat'
})
export class DateFormat implements PipeTransform {
    transform(value: any, args: string[]): any {
        if (value) {
            var date = value instanceof Date ? value : new Date(value);
            return DateFormatter.format(date, 'pt', 'dd/MM/yyyy');
        }
    }
}

Tim S. was much closer to a "correct" answer then the currently accepted one. If you want to have a 100% width, variable height background image done with CSS, instead of using cover (which will allow the image to extend out from the sides) or contain (which does not allow the image to extend out at all), just set the CSS like so:

body {
    background-image: url(img.jpg);
    background-position: center top;
    background-size: 100% auto;
}

This will set your background image to 100% width and allow the height to overflow. Now you can use media queries to swap out that image instead of relying on JavaScript.

EDIT: I just realized (3 months later) that you probably don't want the image to overflow; you seem to want the container element to resize based on it's background-image (to preserve it's aspect ratio), which is not possible with CSS as far as I know.

Hopefully soon you'll be able to use the new srcset attribute on the img element. If you want to use img elements now, the currently accepted answer is probably best.

However, you can create a responsive background-image element with a constant aspect ratio using purely CSS. To do this, you set the height to 0 and set the padding-bottom to a percentage of the element's own width, like so:

.foo {
    height: 0;
    padding: 0; /* remove any pre-existing padding, just in case */
    padding-bottom: 75%; /* for a 4:3 aspect ratio */
    background-image: url(foo.png);
    background-position: center center;
    background-size: 100%;
    background-repeat: no-repeat;
}

In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value. This works because padding percentage is always calculated based on width, even if it's vertical padding.

Superkey - An attribute or set of attributes that uniquely defines a tuple within a relation. However, a superkey may contain additional attributes that are not necessary for unique identification.

Candidate key - A superkey such that no proper subset is a superkey within the relation. So, basically has two properties: Each candidate key uniquely identifies tuple in the relation ; & no proper subset of the composite key has the uniqueness property.

Composite key - When a candidate key consists of more than one attribute.

Primary key - The candidate key chosen to identify tuples uniquely within the relation.

Alternate key - Candidate key that is not a primary key.

Foreign key - An attribute or set of attributes within a relation that matches the candidate key of some relation.

Christoph's answer is perfect. Sometimes however you may want to go more classes up than one. In this case you could try the @at-root and #{} css features which would enable two root classes to sit next to each other using &.

This wouldn't work (due to the nothing before & rule):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    .desc& {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

But this would (using @at-root plus #{&}):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    @at-root .desc#{&} {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

Your problem is that class B is not declared as a "new-style" class. Change it like so:

class B(object):

and it will work.

super() and all subclass/superclass stuff only works with new-style classes. I recommend you get in the habit of always typing that (object) on any class definition to make sure it is a new-style class.

Old-style classes (also known as "classic" classes) are always of type classobj; new-style classes are of type type. This is why you got the error message you saw:

TypeError: super() argument 1 must be type, not classobj

Try this to see for yourself:

class OldStyle:
    pass

class NewStyle(object):
    pass

print type(OldStyle)  # prints: <type 'classobj'>

print type(NewStyle) # prints <type 'type'>

Note that in Python 3.x, all classes are new-style. You can still use the syntax from the old-style classes but you get a new-style class. So, in Python 3.x you won't have this problem.

Try this

$client = new \GuzzleHttp\Client();
$client->post(
    'http://www.example.com/user/create',
    array(
        'form_params' => array(
            'email' => '[email protected]',
            'name' => 'Test user',
            'password' => 'testpassword'
        )
    )
);

Since java 8 just use ZonedDateTime.parse("2010-04-05T17:16:00Z")

In order to approach to Modular design pattern, you need to understand these concept first:

Immediately-Invoked Function Expression (IIFE):

(function() {
      // Your code goes here 
}());

There are two ways you can use the functions. 1. Function declaration 2. Function expression.

Here are using function expression.

What is namespace? Now if we add the namespace to the above piece of code then

var anoyn = (function() {
}());

What is closure in JS?

It means if we declare any function with any variable scope/inside another function (in JS we can declare a function inside another function!) then it will count that function scope always. This means that any variable in outer function will be read always. It will not read the global variable (if any) with the same name. This is also one of the objective of using modular design pattern avoiding naming conflict.

var scope = "I am global";
function whatismyscope() {
    var scope = "I am just a local";
    function func() {return scope;}
    return func;
}
whatismyscope()()

Now we will apply these three concepts I mentioned above to define our first modular design pattern:

var modularpattern = (function() {
    // your module code goes here
    var sum = 0 ;

    return {
        add:function() {
            sum = sum + 1;
            return sum;
        },
        reset:function() {
            return sum = 0;    
        }  
    }   
}());
alert(modularpattern.add());    // alerts: 1
alert(modularpattern.add());    // alerts: 2
alert(modularpattern.reset());  // alerts: 0

jsfiddle for the code above.

The objective is to hide the variable accessibility from the outside world.

Hope this helps. Good Luck.

You can use calc:

height: calc(100% - 18px);

Note that some old browsers don't support the CSS3 calc() function, so implementing the vendor-specific versions of the function may be required:

/* Firefox */
height: -moz-calc(100% - 18px);
/* WebKit */
height: -webkit-calc(100% - 18px);
/* Opera */
height: -o-calc(100% - 18px);
/* Standard */
height: calc(100% - 18px);

I sorted this problem by verifying the json on JSONLint.com and then using Jackson. Below is the code for the same.

 Main Class:-

String jsonStr = "[{\r\n" + "       \"name\": \"John\",\r\n" + "        \"city\": \"Berlin\",\r\n"
                + "         \"cars\": [\r\n" + "            \"FIAT\",\r\n" + "          \"Toyata\"\r\n"
                + "     ],\r\n" + "     \"job\": \"Teacher\"\r\n" + "   },\r\n" + " {\r\n"
                + "     \"name\": \"Mark\",\r\n" + "        \"city\": \"Oslo\",\r\n" + "        \"cars\": [\r\n"
                + "         \"VW\",\r\n" + "            \"Toyata\"\r\n" + "     ],\r\n"
                + "     \"job\": \"Doctor\"\r\n" + "    }\r\n" + "]";

        ObjectMapper mapper = new ObjectMapper();

        MyPojo jsonObj[] = mapper.readValue(jsonStr, MyPojo[].class);

        for (MyPojo itr : jsonObj) {

            System.out.println("Val of getName is: " + itr.getName());
            System.out.println("Val of getCity is: " + itr.getCity());
            System.out.println("Val of getJob is: " + itr.getJob());
            System.out.println("Val of getCars is: " + itr.getCars() + "\n");

        }

POJO:

public class MyPojo {

private List<String> cars = new ArrayList<String>();

private String name;

private String job;

private String city;

public List<String> getCars() {
    return cars;
}

public void setCars(List<String> cars) {
    this.cars = cars;
}

public String getName() {
    return name;
}

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

public String getJob() {
    return job;
}

public void setJob(String job) {
    this.job = job;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
} }

  RESULT:-
         Val of getName is: John
         Val of getCity is: Berlin
         Val of getJob is: Teacher
         Val of getCars is: [FIAT, Toyata]

          Val of getName is: Mark
          Val of getCity is: Oslo
          Val of getJob is: Doctor
          Val of getCars is: [VW, Toyata]

another way to do it:

<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                    <StackPanel>
                        <Image Source="{Binding ProductImage,RelativeSource={RelativeSource TemplatedParent}}" Stretch="Fill" Width="65" Height="85"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Button x:Name="myButton" Width="40" Height="10">
                            <Popup Width="100" Height="70" IsOpen="{Binding ElementName=myButton,Path=IsMouseOver, Mode=OneWay}">
                                <StackPanel Background="Yellow">
                                    <ItemsControl ItemsSource="{Binding Produkt.SubProducts}"/>
                                </StackPanel>
                            </Popup>
                        </Button>
                    </StackPanel>
                </Border>

If time complexity is not an issue, then You can run bubble sort and within two iterations, you will get your second highest number because in the first iteration of the loop, the largest number will be moved to the last. In the second iteration, the second largest number will be moved next to last.

You're looking for the zip builtin function. From the docs:

>>> x = [1, 2, 3]
>>> y = [4, 5, 6]
>>> zipped = zip(x, y)
>>> zipped
[(1, 4), (2, 5), (3, 6)]

You can also mock your property configuration into your test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class MyTest 
{ 
   @Configuration
   public static class MockConfig{
       @Bean
       public Properties myProps(){
             Properties properties = new Properties();
             properties.setProperty("default.url", "myUrl");
             properties.setProperty("property.value2", "value2");
             return properties;
        }
   }
   @Value("#{myProps['default.url']}")
   private String defaultUrl;

   @Test
   public void testValue(){
       Assert.assertEquals("myUrl", defaultUrl);
   }
}

I think this is the minimal code to implement it:

i=0,a={valueOf:()=>++i}_x000D_
_x000D_
if (a == 1 && a == 2 && a == 3) {_x000D_
  console.log('Mind === Blown');_x000D_
}

Creating a dummy object with a custom valueOf that increments a global variable i on each call. 23 characters!

All objects in python are implemented via references so the distinction between objects and pointers to objects does not exist in source code.

The python equivalent of NULL is called None (good info here). As all objects in python are implemented via references, you can re-write your struct to look like this:

class Node:
    def __init__(self): #object initializer to set attributes (fields)
        self.val = 0
        self.right = None
        self.left = None

And then it works pretty much like you would expect:

node = Node()
node.val = some_val #always use . as everything is a reference and -> is not used
node.left = Node()

Note that unlike in NULL in C, None is not a "pointer to nowhere": it is actually the only instance of class NoneType. Therefore, as None is a regular object, you can test for it just like any other object:

if node.left == None:
   print("The left node is None/Null.")

Although since None is a singleton instance, it is considered more idiomatic to use is and compare for reference equality:

if node.left is None:
   print("The left node is None/Null.")

If you use the nextLine() method immediately following the nextInt() method, nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty). So we read can read the empty space to another string might work. Check below code.

import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        int i = scan.nextInt();
        Double d = scan.nextDouble();
        String f = scan.nextLine();
        String s = scan.nextLine();


        // Write your code here.

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
         System.out.println("Int: " + i);
    }
}

I my case adding android:fillViewport="true" solved the issue

You might be needing a cleanup:

git gc --prune=now

or you might be needing a prune:

git remote prune public

prune

Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".

With --dry-run option, report what branches will be pruned, but do no actually prune them.

However, it appears these should have been cleaned up earlier with

git remote rm public 

rm

Remove the remote named <name>. All remote tracking branches and configuration settings for the remote are removed.

So it might be you hand-edited your config file and this did not occur, or you have privilege problems.

Maybe run that again and see what happens.

Advice Context

If you take a look in the revision logs, you'll note I suggested more "correct" techniques, which for whatever reason didn't want to work on their repository.

I suspected the OP had done something that left their tree in an inconsistent state that caused it to behave a bit strangely, and git gc was required to fix up the left behind cruft.

Usually git branch -rd origin/badbranch is sufficient for nuking a local tracking branch , or git push origin :badbranch for nuking a remote branch, and usually you will never need to call git gc

I personally prefer the for (;;) idiom (coming from a C/C++ point of view). While I agree that the while (true) is more readable in a sense (and it's what I used way back when even in C/C++), I've turned to using the for idiom because:

• it stands out

I think the fact that a loop doesn't terminate (in a normal fashion) is worth 'calling out', and I think that the for (;;) does this a bit more.

Hey so I stumbled upon this and got it working, here is how:

inside my component.html

<mat-paginator #paginator [pageSize]="pageSize" [pageSizeOptions]="[5, 10, 20]" [showFirstLastButtons]="true" [length]="totalSize"
    [pageIndex]="currentPage" (page)="pageEvent = handlePage($event)">
</mat-paginator>

Inside my component.ts

public array: any;
public displayedColumns = ['', '', '', '', ''];
public dataSource: any;    

public pageSize = 10;
public currentPage = 0;
public totalSize = 0;

@ViewChild(MatPaginator) paginator: MatPaginator;

constructor(private app: AppService) { }

ngOnInit() {
  this.getArray();
}

public handlePage(e: any) {
  this.currentPage = e.pageIndex;
  this.pageSize = e.pageSize;
  this.iterator();
}

private getArray() {
  this.app.getDeliveries()
    .subscribe((response) => {
      this.dataSource = new MatTableDataSource<Element>(response);
      this.dataSource.paginator = this.paginator;
      this.array = response;
      this.totalSize = this.array.length;
      this.iterator();
    });
}

private iterator() {
  const end = (this.currentPage + 1) * this.pageSize;
  const start = this.currentPage * this.pageSize;
  const part = this.array.slice(start, end);
  this.dataSource = part;
}

All the paging work is done from within the iterator method. This method works out the skip and take and assigns that to the dataSource for the Material table.

In my case it is a different issue. The database turned into single user mode and a second connection to the database was showing this exception. To resolve this issue follow below steps.

1. Make sure the object explorer is pointed to a system database like master.
2. Execute a exec sp_who2 and find all the connections to database ‘my_db’. Kill all the connections by doing KILL { session id } where session id is the SPID listed by sp_who2.

USE MASTER;
EXEC sp_who2

3. Alter the database

USE MASTER;
ALTER DATABASE [my_db] SET MULTI_USER
GO

JavaScript's Date object supports the ISO date format, so as long as you have access to the date string, you can do something like this:

> foo = new Date("2012-07-14T01:00:00+01:00")
Sat, 14 Jul 2012 00:00:00 GMT
> foo.toTimeString()
'17:00:00 GMT-0700 (MST)'

If you want the time string without the seconds and the time zone then you can call the getHours() and getMinutes() methods on the Date object and format the time yourself.

Python's power operator is ** and Euler's number is math.e, so:

Building on Graham's answer, the extra code saves the workbook back into it's original location in it's original format.

Public Sub SaveWorksheetsAsCsv()

Dim WS As Excel.Worksheet
Dim SaveToDirectory As String

Dim CurrentWorkbook As String
Dim CurrentFormat As Long

 CurrentWorkbook = ThisWorkbook.FullName
 CurrentFormat = ThisWorkbook.FileFormat
' Store current details for the workbook

      SaveToDirectory = "C:\"

      For Each WS In ThisWorkbook.Worksheets
          WS.SaveAs SaveToDirectory & WS.Name, xlCSV
      Next

 Application.DisplayAlerts = False
  ThisWorkbook.SaveAs Filename:=CurrentWorkbook, FileFormat:=CurrentFormat
 Application.DisplayAlerts = True
' Temporarily turn alerts off to prevent the user being prompted

If it is a symmetrical (rectangular) array then Try pushing into a single dimension javascript array; use razor to determine the array structure; and then transform into a 2 dimensional array.

// this just sticks them all in a one dimension array of rows * cols
var myArray = new Array();
@foreach (var d in Model.ResultArray)
{
    @:myArray.push("@d");
}

var MyA = new Array();

var rows = @Model.ResultArray.GetLength(0);
var cols = @Model.ResultArray.GetLength(1);

// now convert the single dimension array to 2 dimensions
var NewRow;
var myArrayPointer = 0;

for (rr = 0; rr < rows; rr++)
{
  NewRow = new Array();
  for ( cc = 0; cc < cols; cc++)
  {
    NewRow.push(myArray[myArrayPointer]);
    myArrayPointer++;
  }
  MyA.push(NewRow);
}

Well, use a bloom filter.

int findmissing(int arr[], int n)
{
    long bloom=0;
    int i;
    for(i=0; i<;n; i++)bloom+=1>>arr[i];
    for(i=1; i<=n, (bloom<<i & 1); i++);
    return i;
}

You need to use an id selector:

 //show
 $('#passwordsNoMatchRegister').show();
 //hide
 $('#passwordsNoMatchRegister').hide();

# is an id selector and passwordsNoMatchRegister is the id of the div.

This is the deep cloning method I use, I think it Great, hope you make suggestions

function deepClone (obj) {
    var _out = new obj.constructor;

    var getType = function (n) {
        return Object.prototype.toString.call(n).slice(8, -1);
    }

    for (var _key in obj) {
        if (obj.hasOwnProperty(_key)) {
            _out[_key] = getType(obj[_key]) === 'Object' || getType(obj[_key]) === 'Array' ? deepClone(obj[_key]) : obj[_key];
        }
    }
    return _out;
}

I encountered the same error, just add "--force" to the command, it works

    for j in range(0, 1000):

        # Split the current line into a list: line
        line = file.readline().split(',')

        # Get the value for the first column: first_col
        first_col = line[0]

        # If the column value is in the dict, increment its value
        if first_col in counts_dict.keys():
            counts_dict[first_col] += 1

        # Else, add to the dict and set value to 1
        else:
            counts_dict[first_col] = 1

# Print the resulting dictionary
print(counts_dict)

I had to look a little more to solve my problem but what solved it was finding where the error was. Here It shows how to do that in Jquery's error dump.

In my case id was empty and $("#" + id);; produces the error.

It was where I wasn't looking so that helped pinpoint where it was so I could troubleshoot and fix it.

A UNIX guy probably told you that. :)

You can use makefiles in VS, but when you do it bypasses all the built-in functionality in MSVC's IDE. Makefiles are basically the reinterpret_cast of the builder. IMO the simplest thing is just to use Solutions.

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

        db.execSQL(CREATE_TABLE_TIMELINE);
        db.execSQL("INSERT INTO ddd (name) VALUES ('One')");
        db.execSQL("INSERT INTO ddd (name) VALUES ('Two')");
        db.execSQL("INSERT INTO ddd (name) VALUES ('Three')");
    }

    @Override

        String selectQuery = "SELECT  * FROM table_name;
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.rawQuery(selectQuery, null);
        return cursor;
    }
}

*Updated

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

After a while trying to build a function to get an integer with the last row in a single column, this worked fine:

    function lastRow() {
    var spreadsheet = SpreadsheetApp.getActiveSheet();
    spreadsheet.getRange('B1').activate();
    var columnB = spreadsheet.getSelection().getNextDataRange(SpreadsheetApp.Direction.DOWN).activate();
    var numRows = columnB.getLastRow();
    var nextRow = numRows + 1; 
    }

You can use an out parameter instead of the return value if you want both a result set and a return value

CREATE PROCEDURE proc_name 
@param int out
AS
BEGIN
    SET @param = value
SELECT ... FROM [Table] WHERE Condition
END
GO

You can simply solve this problem using usort() with callback function. No need to write any custom function.

$your_date_field_name = 'datetime';
usort($your_given_array_name, function ($a, $b) use (&$your_date_field_name) {
    return strtotime($a[$your_date_field_name]) - strtotime($b[$your_date_field_name]);
});

Task.WaitAll blocks the current thread until everything has completed.

Task.WhenAll returns a task which represents the action of waiting until everything has completed.

That means that from an async method, you can use:

await Task.WhenAll(tasks);

... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.

Beware of ORDER BY RAND() because of performance and results. Check this article out: http://jan.kneschke.de/projects/mysql/order-by-rand/

this seems to be working nicely for me

$(window).bind('resize', function() {
    jQuery("#grid").setGridWidth($('#parentDiv').width()-30, true);
}).trigger('resize');

The following plpython snippet might come in handy.

CREATE EXTENSION IF NOT EXISTS plpythonu;
CREATE LANGUAGE plpythonu;

CREATE OR REPLACE FUNCTION json_update(data json, key text, value text)
 RETURNS json
 AS $$
    import json
    json_data = json.loads(data)
    json_data[key] = value
    return json.dumps(json_data, indent=4)
 $$ LANGUAGE plpythonu;

-- Check how JSON looks before updating

SELECT json_update(content::json, 'CFRDiagnosis.mod_nbs', '1')
FROM sc_server_centre_document WHERE record_id = 35 AND template = 'CFRDiagnosis';

-- Once satisfied update JSON inplace

UPDATE sc_server_centre_document SET content = json_update(content::json, 'CFRDiagnosis.mod_nbs', '1')
WHERE record_id = 35 AND template = 'CFRDiagnosis';

I tried to manage using the below command. This will write the output in log file as well as print on console.

#!/bin/bash

# Log Location on Server.
LOG_LOCATION=/home/user/scripts/logs
exec > >(tee -i $LOG_LOCATION/MylogFile.log)
exec 2>&1

echo "Log Location should be: [ $LOG_LOCATION ]"

Please note: This is bash code so if you run it using sh it will through syntax error

In addition to the above, you might be interested in displaying your current directory:

int MAX_PATH_LENGTH = 80;
char* path[MAX_PATH_LENGTH];
getcwd(path, MAX_PATH_LENGTH);
printf("Current Directory = %s", path);

This should work without issue on a gcc/glibc platform. (I'm most familiar with that type of platform). There was a question posted here that talked about getcwd & Visual Studio if you're on a Windows type platform.

The difference can be demonstrated by this example:

1. generate a matrix

   >>> A = numpy.matrix(numpy.ones((3,3)))
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

2. use numpy.array to modify A. Doesn't work because you are modifying a copy

   >>> numpy.array(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

3. use numpy.asarray to modify A. It worked because you are modifying A itself

   >>> numpy.asarray(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 2.,  2.,  2.]])
   

Hope this helps!

I have issue with large calculation in sp_foo that take large time so i fixed

You could use p2pkit, or the free solution it was based on: https://github.com/GitGarage. Doesn't work very well, and its a fixer-upper for sure, but its, well, free. Works for small amounts of data transfer right now.

I am using React 16.6.3 and @Material UI 3.5.1, and is able to use arrays in className like className={[classes.tableCell, classes.capitalize]}

So in your example, the following would be similar.

<li key={index} className={[activeClass, data.class, "main-class"]}></li>

In case this page comes up in someones web search, as of Java 1.7 you can now use java.nio.charset.StandardCharsets to get access to constant definitions of standard charsets.

You're swapping endianness between your two methods. You have intToByteArray(int a) assigning the low-order bits into ret[0], but then byteArrayToInt(byte[] b) assigns b[0] to the high-order bits of the result. You need to invert one or the other, like:

public static byte[] intToByteArray(int a)
{
    byte[] ret = new byte[4];
    ret[3] = (byte) (a & 0xFF);   
    ret[2] = (byte) ((a >> 8) & 0xFF);   
    ret[1] = (byte) ((a >> 16) & 0xFF);   
    ret[0] = (byte) ((a >> 24) & 0xFF);
    return ret;
}

After learning what it is all about, I thought to write a hopefully simpler explanation via analogy:

Summary: What is a hashcode?

• It's a fingerprint. We can use this finger print to identify people of interest.

Read below for more details:

Think of a Hashcode as us trying to To Uniquely Identify Someone

I am a detective, on the look out for a criminal. Let us call him Mr Cruel. (He was a notorious murderer when I was a kid -- he broke into a house kidnapped and murdered a poor girl, dumped her body and he's still out on the loose - but that's a separate matter). Mr Cruel has certain peculiar characteristics that I can use to uniquely identify him amongst a sea of people. We have 25 million people in Australia. One of them is Mr Cruel. How can we find him?

Bad ways of Identifying Mr Cruel

Apparently Mr Cruel has blue eyes. That's not much help because almost half the population in Australia also has blue eyes.

Good ways of Identifying Mr Cruel

What else can i use? I know: I will use a fingerprint!

Advantages:

• It is really really hard for two people to have the same finger print (not impossible, but extremely unlikely).
• Mr Cruel's fingerprint will never change.
• Every single part of Mr Cruel's entire being: his looks, hair colour, personality, eating habits etc must (ideally) be reflected in his fingerprint, such that if he has a brother (who is very similar but not the same) - then both should have different finger prints. I say "should" because we cannot guarantee 100% that two people in this world will have different fingerprints.
• But we can always guarantee that Mr Cruel will always have the same finger print - and that his fingerprint will NEVER change.

The above characteristics generally make for good hash functions.

So what's the deal with 'Collisions'?

So imagine if I get a lead and I find someone matching Mr Cruel's fingerprints. Does this mean I have found Mr Cruel?

........perhaps! I must take a closer look. If i am using SHA256 (a hashing function) and I am looking in a small town with only 5 people - then there is a very good chance I found him! But if I am using MD5 (another famous hashing function) and checking for fingerprints in a town with +2^1000 people, then it is a fairly good possibility that two entirely different people might have the same fingerprint.

So what is the benefit of all this anyways?

The only real benefit of hashcodes is if you want to put something in a hash table - and with hash tables you'd want to find objects quickly - and that's where the hash code comes in. They allow you to find things in hash tables really quickly. It's a hack that massively improves performance, but at a small expense of accuracy.

So let's imagine we have a hash table filled with people - 25 million suspects in Australia. Mr Cruel is somewhere in there..... How can we find him really quickly? We need to sort through them all: to find a potential match, or to otherwise acquit potential suspects. You don't want to consider each person's unique characteristics because that would take too much time. What would you use instead? You'd use a hashcode! A hashcode can tell you if two people are different. Whether Joe Bloggs is NOT Mr Cruel. If the prints don't match then you know it's definitely NOT Mr Cruel. But, if the finger prints do match then depending on the hash function you used, chances are already fairly good you found your man. But it's not 100%. The only way you can be certain is to investigate further: (i) did he/she have an opportunity/motive, (ii) witnesses etc etc.

When you are using computers if two objects have the same hash code value, then you again need to investigate further whether they are truly equal. e.g. You'd have to check whether the objects have e.g. the same height, same weight etc, if the integers are the same, or if the customer_id is a match, and then come to the conclusion whether they are the same. this is typically done perhaps by implementing an IComparer or IEquality interfaces.

Key Summary

So basically a hashcode is a finger print.

1. Two different people/objects can theoretically still have the same fingerprint. Or in other words. If you have two fingerprints that are the same.........then they need not both come from the same person/object.
2. Buuuuuut, the same person/object will always return the same fingerprint.
3. Which means that if two objects return different hash codes then you know for 100% certainty that those objects are different.

It takes a good 3 minutes to get your head around the above. Perhaps read it a few times till it makes sense. I hope this helps someone because it took a lot of grief for me to learn it all!

mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
        RadioButton radioButton = (RadioButton)group.findViewById(checkedId);
    }
});

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

select one.*, two.meal
from table1 as one
left join table2 as two
on (one.weddingtable = two.weddingtable and one.tableseat = two.tableseat)

As mentioned before, you might need GD library installed.

On a shell, check your php version first:
php -v

Then install accordingly. In my system (Linux-Ubuntu) it's php version 7.0:
sudo apt-get install php7.0-gd

Restart your webserver:
systemctl restart apache2

You should now have GD library installed and enabled.

Create .gitignore file in root folder directly by code editor or by command

For Mac & Linux

 touch .gitignore 

For Windows

 echo >.gitignore 

open .gitignore declare folder or file name like this /foldername

Using [Authorize] attributes can help prevent security holes in your application. The way that MVC handles URL's (i.e. routing them to a controller rather than to an actual file) makes it difficult to actually secure everything via the web.config file.

I found that this can happen if the referenced project is targeting a higher version of the framework than the project that is trying to use it. You can tell if this is the problem by going to the output window and looking for something similar to this:

The primary reference "my_reference" could not be resolved because it was built against the ".NETFramework,Version=v4.7.2" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.7".

The solution is to change the target framework of one or other of the projects.

Try string.Remove();

string str = "1,5,12,34,";
string removecomma = str.Remove(str.Length-1);
MessageBox.Show(removecomma);

image container

Scaling images using the above trick only works if the container the images are in changes size.

The #icons container uses px values for the width and height. px values don't scale when the browser is resized.

Solutions

Use one of the following approaches:

1. Define the width and/or height using % values.
2. Use a series of @media queries to set the width and height to different values based on the current screen size.

My solution in Header parameters with example is user="test" is:

@RequestMapping(value = "/restURL")
  public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers){

System.out.println(headers.get("user"));
}

How to update the current menu in order to enable or disable the items when an AsyncTask is done.

In my use case I needed to disable my menu while my AsyncTask was loading data, then after loading all the data, I needed to enable all the menu again in order to let the user use it.

This prevented the app to let users click on menu items while data was loading.

First, I declare a state variable , if the variable is 0 the menu is shown, if that variable is 1 the menu is hidden.

private mMenuState = 1; //I initialize it on 1 since I need all elements to be hidden when my activity starts loading.

Then in my onCreateOptionsMenu() I check for this variable , if it's 1 I disable all my items, if not, I just show them all

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_galeria_pictos, menu);

        if(mMenuState==1){
            for (int i = 0; i < menu.size(); i++) {
                menu.getItem(i).setVisible(false);
            }
        }else{
             for (int i = 0; i < menu.size(); i++) {
                menu.getItem(i).setVisible(true);
            }
        }

        return super.onCreateOptionsMenu(menu);
    }

Now, when my Activity starts, onCreateOptionsMenu() will be called just once, and all my items will be gone because I set up the state for them at the start.

Then I create an AsyncTask Where I set that state variable to 0 in my onPostExecute()

This step is very important!

When you call invalidateOptionsMenu(); it will relaunch onCreateOptionsMenu();

So, after setting up my state to 0, I just redraw all the menu but this time with my variable on 0 , that said, all the menu will be shown after all the asynchronous process is done, and then my user can use the menu.

 public class LoadMyGroups extends AsyncTask<Void, Void, Void> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            mMenuState = 1; //you can set here the state of the menu too if you dont want to initialize it at global declaration. 

        }

        @Override
        protected Void doInBackground(Void... voids) {
           //Background work

            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {
            super.onPostExecute(aVoid);

            mMenuState=0; //We change the state and relaunch onCreateOptionsMenu
            invalidateOptionsMenu(); //Relaunch onCreateOptionsMenu

        }
    }

Results

You don't even need to use do and done. For infinite loops I find it more readable to use for with curly brackets. For example:

for ((;;)) { date ; sleep 1 ; }

This works in bash and zsh. Doesn't work in sh.

I use the Branches options, and then right click on the "remote/origin" folder and then click on "delete branches from remote", see the image below:

Here you go:

Type type = new TypeToken<Map<String, String>>(){}.getType();
Map<String, String> myMap = gson.fromJson("{'k1':'apple','k2':'orange'}", type);

The best way to put is that hg forget is identical to hg remove except that it leaves the files behind in your working copy. The files are left behind as untracked files and can now optionally be ignored with a pattern in .hgignore.

In other words, I cannot tell if you used hg forget or hg remove when I pull from you. A file that you ran hg forget on will be deleted when I update to that changeset — just as if you had used hg remove instead.

This is one way I found. You can add a hidden button:

<button id="openModalButton" [hidden]="true" data-toggle="modal" data-target="#myModal">Open Modal</button>

Then use the code to "click" the button to open the modal:

document.getElementById("openModalButton").click();

This way can keep the bootstrap style of the modal and the fade in animation.

Just as an FYI, here is my working code:

src_dir = "C:\\temp\\CSV\\"
target_dir = "C:\\temp\\output2\\"
keyword = "KEYWORD"

for f in os.listdir(src_dir):
    file_name = os.path.join(src_dir, f)
    out_file = os.path.join(target_dir, f)
    with open(file_name, "r+") as fi, open(out_file, "w") as fo:
        for line in fi:
            if keyword not in line:
                fo.write(line)

Thanks again to everyone for all the great feedback!

It denotes an rvalue reference. Rvalue references will only bind to temporary objects, unless explicitly generated otherwise. They are used to make objects much more efficient under certain circumstances, and to provide a facility known as perfect forwarding, which greatly simplifies template code.

In C++03, you can't distinguish between a copy of a non-mutable lvalue and an rvalue.

std::string s;
std::string another(s);           // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(const std::string&);

In C++0x, this is not the case.

std::string s;
std::string another(s);           // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(std::string&&);

Consider the implementation behind these constructors. In the first case, the string has to perform a copy to retain value semantics, which involves a new heap allocation. However, in the second case, we know in advance that the object which was passed in to our constructor is immediately due for destruction, and it doesn't have to remain untouched. We can effectively just swap the internal pointers and not perform any copying at all in this scenario, which is substantially more efficient. Move semantics benefit any class which has expensive or prohibited copying of internally referenced resources. Consider the case of std::unique_ptr- now that our class can distinguish between temporaries and non-temporaries, we can make the move semantics work correctly so that the unique_ptr cannot be copied but can be moved, which means that std::unique_ptr can be legally stored in Standard containers, sorted, etc, whereas C++03's std::auto_ptr cannot.

Now we consider the other use of rvalue references- perfect forwarding. Consider the question of binding a reference to a reference.

std::string s;
std::string& ref = s;
(std::string&)& anotherref = ref; // usually expressed via template

Can't recall what C++03 says about this, but in C++0x, the resultant type when dealing with rvalue references is critical. An rvalue reference to a type T, where T is a reference type, becomes a reference of type T.

(std::string&)&& ref // ref is std::string&
(const std::string&)&& ref // ref is const std::string&
(std::string&&)&& ref // ref is std::string&&
(const std::string&&)&& ref // ref is const std::string&&

Consider the simplest template function- min and max. In C++03 you have to overload for all four combinations of const and non-const manually. In C++0x it's just one overload. Combined with variadic templates, this enables perfect forwarding.

template<typename A, typename B> auto min(A&& aref, B&& bref) {
    // for example, if you pass a const std::string& as first argument,
    // then A becomes const std::string& and by extension, aref becomes
    // const std::string&, completely maintaining it's type information.
    if (std::forward<A>(aref) < std::forward<B>(bref))
        return std::forward<A>(aref);
    else
        return std::forward<B>(bref);
}

I left off the return type deduction, because I can't recall how it's done offhand, but that min can accept any combination of lvalues, rvalues, const lvalues.

Check out FPDF (with FPDI):

http://www.fpdf.org/

http://www.setasign.de/products/pdf-php-solutions/fpdi/

These will let you open an pdf and add content to it in PHP. I'm guessing you can also use their functionality to search through the existing content for the values you need.

Another possible library is TCPDF: https://tcpdf.org/

Update to add a more modern library: PDF Parser

From the manual page:

-P prefix
--directory-prefix=prefix
           Set directory prefix to prefix.  The directory prefix is the
           directory where all other files and sub-directories will be
           saved to, i.e. the top of the retrieval tree.  The default
           is . (the current directory).

So you need to add -P /tmp/cron_test/ (short form) or --directory-prefix=/tmp/cron_test/ (long form) to your command. Also note that if the directory does not exist it will get created.

A few comments:

1. Since the search position is important you should specify where you start the search. I use ws.[a1] and xlNext below so my search starts in A2 of the specified sheet.
2. Some of Finds arguments - including lookat use the prior search settings. So you should always specify xlWhole or xlPart to match all or part a string respectively.
3. You can do all you want - including inserting a row, and prompting the user for a new value (my code will suggest 20 if the prior value was 19) without using Select or Activate

suggested code

Sub FindEm()
Dim Wb As Workbook
Dim ws As Worksheet
Dim rng1 As Range
Set Wb = ThisWorkbook
Set ws = Wb.Sheets("ECM Overview")
Set rng1 = ws.Range("A:A").Find("ProjTemp", ws.[a1], xlValues, xlWhole, , xlNext)
If Not rng1 Is Nothing Then
rng1.EntireRow.Insert
rng1.Offset(-1, 0).Value = Application.InputBox("Please enter data", "User Data Entry", rng1.Offset(-2, 0) + 1, , , , , 1)
Else
MsgBox "ProjTemp not found", vbCritical
End If
End Sub

Found this post while looking for answers on how to un-delete a file that was deleted in my working directory after a merge from another's branch. No commit was yet made after the merge. Since it was a merge in progress, i could not just add it back using:

$ git reset <commitid#-where-file.cpp-existed> file.cpp

I had to do another step in addition to the reset to bring the file back:

$ git checkout -- file.cpp

I think you can also use BufferedWriter :

BufferedWriter writer = new BufferedWriter(new FileWriter(new File("note.txt")));

String stuffToWrite = info;

writer.write(stuffToWrite);

writer.close();

and before that remember too add

import java.io.BufferedWriter;

Unless you're talking about base 16 numbers (for which there's a method to parse as Hex), you need to explicitly separate out the part that you are interested in, and then convert it. After all, what would be the semantics of something like 23e44e11d in base 10?

Regular expressions could do the trick if you know for sure that you only have one number. Java has a built in regular expression parser.

If, on the other hands, your goal is to concatenate all the digits and dump the alphas, then that is fairly straightforward to do by iterating character by character to build a string with StringBuilder, and then parsing that one.

Use JavaScript objects. You can access their properties like keys in a dictionary. This is the foundation of JSON. The syntax is similar to Python dictionaries. See: JSON.org

You can use XmlDocument. Also some XPath can be useful.

Just a simple example

XmlDocument doc = new XmlDocument();
doc.Load("sample.xml");
XmlElement root = doc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("some_node"); // You can also use XPath here
foreach (XmlNode node in nodes)
{
   // use node variable here for your beeds
}

The Collection interface includes the toArray() method to convert a new collection into an array. There are two forms of this method. The no argument version will return the elements of the collection in an Object array: public Object[ ] toArray(). The returned array cannot cast to any other data type. This is the simplest version. The second version requires you to pass in the data type of the array you’d like to return: public Object [ ] toArray(Object type[ ]).

 public static void main(String[] args) {  
           List<String> l=new ArrayList<String>();  
           l.add("A");  
           l.add("B");  
           l.add("C");  
           Object arr[]=l.toArray();  
           for(Object a:arr)  
           {  
                String str=(String)a;  
                System.out.println(str);  
           }  
      }  

for reference, refer this link http://techno-terminal.blogspot.in/2015/11/how-to-obtain-array-from-arraylist.html

string Value = dic.ContainsKey("Name") ? dic["Name"] : "Required Name"

With this code, we will get string data in 'Value'. If key 'Name' exists in the dictionary 'dic' then fetch this value, else returns "Required Name" string.

In addition to the examples by DigitalRoss, here's another form that you can use if you prefer $() instead of backticks `

echo abc $(: comment) \
     def $(: comment) \
     xyz

Of course, you can use the colon syntax with backticks as well:

echo abc `: comment` \
     def `: comment` \
     xyz

Additional Notes

The reason $(#comment) doesn't work is because once it sees the #, it treats the rest of the line as comments, including the closing parentheses: comment). So the parentheses is never closed.

Backticks parse differently and will detect the closing backtick even after a #.

You Can create a Linear layout containing an array of TextView (mDots). To represent the textView as Dots provide this HTML source in your code . refer my code . I got this information from Youtube Channel TVAC Studio . here the code : `

    addDotsIndicator(0);
    viewPager.addOnPageChangeListener(viewListener);
}

public void addDotsIndicator(int position)
{
        mDots = new TextView[5];
        mDotLayout.removeAllViews();

        for (int i = 0; i<mDots.length ; i++)
        {
             mDots[i]=new TextView(this);
             mDots[i].setText(Html.fromHtml("&#8226;"));            //HTML for dots
             mDots[i].setTextSize(35);
             mDots[i].setTextColor(getResources().getColor(R.color.colorAccent));

             mDotLayout.addView(mDots[i]);
        }

        if(mDots.length>0)
        {
            mDots[position].setTextColor(getResources().getColor(R.color.orange));
        }
}

ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int 
   positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {

        addDotsIndicator(position);
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
};`

This works well

$(function () {
   $('#modal').modal('toggle');
});

However, when you have multiple modals stacking on top one another it is not effective, so instead , this works

data-dismiss="modal"

def f(a,b):
    return a+b

xx = 'f'
print eval('%s(%s,%s)'%(xx,2,3))

OUTPUT

 5

You have to add android:exported="true" in the manifest file in the activity you are trying to start.

From the android:exported documentation:

android:exported
Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

The default value depends on whether the activity contains intent filters. The absence of any filters means that the activity can be invoked only by specifying its exact class name. This implies that the activity is intended only for application-internal use (since others would not know the class name). So in this case, the default value is "false". On the other hand, the presence of at least one filter implies that the activity is intended for external use, so the default value is "true".

This attribute is not the only way to limit an activity's exposure to other applications. You can also use a permission to limit the external entities that can invoke the activity (see the permission attribute).

<?php
//  Use this function and Pass Mixed string and what you want to search in mixed string.
//  For Example :
    $mixedStr = "hello world. This is john duvey";
    $searchStr= "john";

    if(strpos($mixedStr,$searchStr)) {
      echo "Your string here";
    }else {
      echo "String not here";
    }

If you are using Ubuntu/Linux and you are trying to run

php composer.phar require intervention/image on your command line.

Use sudo composer require intervention/image instead. This will give you want you are looking for.

Yes there is a problem with Click event handler (klik) - First argument must be an object type and second must be EventArgs.

public void klik(object sender, EventArgs e) {
  //
}

If you want to paint on a form or control then use CreateGraphics method.

public void klik(object sender, EventArgs e) {
    Bitmap c = this.DrawMandel();
    Graphics gr = CreateGraphics();  // Graphics gr=(sender as Button).CreateGraphics();
    gr.DrawImage(b, 150, 200);
}

They are likely still referenced by the project file. Make sure they are deleted using the Solution Explorer in Visual Studio - it should show them as being missing (with an exclamation mark).

If on Windows and installed using chocolatey make sure firewall is allowing the default ports for it:

netsh advfirewall firewall add rule name="RabbitMQ Management" dir=in action=allow protocol=TCP localport=15672
netsh advfirewall firewall add rule name="RabbitMQ" dir=in action=allow protocol=TCP localport=5672

for the remote access.

Html.TextBox amd Html.DropDownList are not strongly typed and hence they doesn't require a strongly typed view. This means that we can hardcode whatever name we want. On the other hand, Html.TextBoxFor and Html.DropDownListFor are strongly typed and requires a strongly typed view, and the name is inferred from the lambda expression.

Strongly typed HTML helpers also provide compile time checking.

Since, in real time, we mostly use strongly typed views, prefer to use Html.TextBoxFor and Html.DropDownListFor over their counterparts.

Whether, we use Html.TextBox & Html.DropDownList OR Html.TextBoxFor & Html.DropDownListFor, the end result is the same, that is they produce the same HTML.

Strongly typed HTML helpers are added in MVC2.

As already stated ??!??! is essentially two trigraphs (??! and ??! again) mushed together that get replaced-translated to ||, i.e the logical OR, by the preprocessor.

The following table containing every trigraph should help disambiguate alternate trigraph combinations:

Trigraph   Replaces

??(        [
??)        ]
??<        {
??>        }
??/        \
??'        ^
??=        #
??!        |
??-        ~

^{Source: C: A Reference Manual 5th Edition}

So a trigraph that looks like ??(??) will eventually map to [], ??(??)??(??) will get replaced by [][] and so on, you get the idea.

Since trigraphs are substituted during preprocessing you could use cpp to get a view of the output yourself, using a silly trigr.c program:

void main(){ const char *s = "??!??!"; } 

and processing it with:

cpp -trigraphs trigr.c 

You'll get a console output of

void main(){ const char *s = "||"; }

As you can notice, the option -trigraphs must be specified or else cpp will issue a warning; this indicates how trigraphs are a thing of the past and of no modern value other than confusing people who might bump into them.

As for the rationale behind the introduction of trigraphs, it is better understood when looking at the history section of ISO/IEC 646:

ISO/IEC 646 and its predecessor ASCII (ANSI X3.4) largely endorsed existing practice regarding character encodings in the telecommunications industry.

As ASCII did not provide a number of characters needed for languages other than English, a number of national variants were made that substituted some less-used characters with needed ones.

^{(emphasis mine)}

So, in essence, some needed characters (those for which a trigraph exists) were replaced in certain national variants. This leads to the alternate representation using trigraphs comprised of characters that other variants still had around.

FYI - if you are importing a List into a JSP, chances are pretty good that you are violating MVC principles. Take a few hours now to read up on the MVC approach to web app development (including use of taglibs) - do some more googling on the subject, it's fascinating and will definitely help you write better apps.

If you are doing anything more complicated than a single JSP displaying some database results, please consider using a framework like Spring, Grails, etc... It will absolutely take you a bit more effort to get going, but it will save you so much time and effort down the road that I really recommend it. Besides, it's cool stuff :-)

If someone else have got a similar error message, you probably built the app with optimisations(production) flag on and that's why the error message is not that communicative. Another possibility that you have got the error under development (from i386 I know you were using simulator). If that is the case, change the build environment to development and try to reproduce the situation to get a more specific error message.

I'm not really a fan of the most-upvoted answer here (in part because it seems like it isn't correct since it should continue if it reads a null terminator in either string--but not both strings at once--and it doesn't do this), so I wrote my own.

This is a direct drop-in replacement for strncmp(), and has been tested with numerous test cases, as shown below.

It is identical to strncmp() except:

1. It is case-insensitive.
2. The behavior is NOT undefined (it is well-defined) if either string is a null ptr. Regular strncmp() has undefined behavior if either string is a null ptr (see: https://en.cppreference.com/w/cpp/string/byte/strncmp).
3. It returns INT_MIN as a special sentinel error value if either input string is a NULL ptr.

LIMITATIONS: Note that this code works on the original 7-bit ASCII character set only (decimal values 0 to 127, inclusive), NOT on unicode characters, such as unicode character encodings UTF-8 (the most popular), UTF-16, and UTF-32.

Here is the code only (no comments):

int strncmpci(const char * str1, const char * str2, size_t num)
{
    int ret_code = 0;
    size_t chars_compared = 0;

    if (!str1 || !str2)
    {
        ret_code = INT_MIN;
        return ret_code;
    }

    while ((chars_compared < num) && (*str1 || *str2))
    {
        ret_code = tolower((int)(*str1)) - tolower((int)(*str2));
        if (ret_code != 0)
        {
            break;
        }
        chars_compared++;
        str1++;
        str2++;
    }

    return ret_code;
}

TODO:

1. Make a version of this code which also works on Unicode's UTF-8 implementation (character encoding)!

As said, the objectForKey: datatype is :(id)aKey whereas the valueForKey: datatype is :(NSString *)key.

For example:

 NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[NSArray arrayWithObject:@"123"],[NSNumber numberWithInteger:5], nil];

 NSLog(@"objectForKey : --- %@",[dict objectForKey:[NSNumber numberWithInteger:5]]);  
    //This will work fine and prints (    123    )  

 NSLog(@"valueForKey  : --- %@",[dict valueForKey:[NSNumber numberWithInteger:5]]); 
    //it gives warning "Incompatible pointer types sending 'NSNumber *' to parameter of type 'NSString *'"   ---- This will crash on runtime. 

So, valueForKey: will take only a string value and is a KVC method, whereas objectForKey: will take any type of object.

The value in objectForKey will be accessed by the same kind of object.

Here, using your notation:

var data = {
    'PropertyA': 1,
    'PropertyB': 2,
    'PropertyC': 3
};
var propName = 'Property' + someUserInput
//imagine someUserInput was 'Z', how can I now add a 'PropertyZ' property to 
//my object?
data[propName] = 'Some New Property value'

you can try this:

$('div#someDiv').height('');

You can do this only from an XML file too.

Create a color.xml file in the values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="textbody">#ffcc33</color>

</resources>

Then in any XML file, you can set color for text using,

android:textColor="@color/textbody"

Or you can use this color in a Java file:

final TextView tvchange12 = (TextView) findViewById(R.id.textView2);
//Set color for textbody from color.xml file
tvchange1.setTextColor(getResources().getColor(R.color.textbody));

Generate a number in the range from 100000 to 999999.

// pseudo code
int n = 100000 + random_float() * 900000;

For more details see the documentation for Random

It should be in %USERNAME%. Obviously this can be easily spoofed, so don't rely on it for security.

Useful tip: type set in a command prompt will list all environment variables.

You can use the status command in MySQL client.

I had the same problem with openCV on Raspberry Pi... don't know if this can solve your problem, but what worked for me was

import time
import cv2


cap = cv2.VideoCapture(0)

cap.set(3,1280)

cap.set(4,1024)

time.sleep(2)

cap.set(15, -8.0)

the time you have to use can be different

You were almost there:

You just need to append the li to ul and voila!

So just add

ul.appendChild(li);

to the end of your function so the end function will be like this:

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Element 4"));
  ul.appendChild(li);
}

For me it worked by adding android:textAllCaps="true" and android:inputType="textCapCharacters"

<android.support.design.widget.TextInputEditText
                    android:layout_width="fill_parent"
                    android:layout_height="@dimen/edit_text_height"
                    android:textAllCaps="true"
                    android:inputType="textCapCharacters"
                    />

I found a good example of what you need in this link.

import javax.swing.JFileChooser;

public class Main {
  public static void main(String s[]) {
    JFileChooser chooser = new JFileChooser();
    chooser.setCurrentDirectory(new java.io.File("."));
    chooser.setDialogTitle("choosertitle");
    chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    chooser.setAcceptAllFileFilterUsed(false);

    if (chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {
      System.out.println("getCurrentDirectory(): " + chooser.getCurrentDirectory());
      System.out.println("getSelectedFile() : " + chooser.getSelectedFile());
    } else {
      System.out.println("No Selection ");
    }
  }
}

Not wanting to edit my git config file I followed the info in @mipadi's post and used:

$ git pull origin master

If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;

wget --no-verbose --no-parent --recursive --level=1\
--no-directories --user=login --password=pass ftp://ftp.myftpsite.com/

• --no-parent : Do not ever ascend to the parent directory when retrieving recursively.
• --level=depth : Specify recursion maximum depth level depth. The default maximum depth is five layers.
• --no-directories : Do not create a hierarchy of directories when retrieving recursively.

Package names are guaranteed to be unique so you can use the Log function with the tag as your package name and then filter by package name:

NOTE: As of Build Tools 21.0.3 this will no longer work as TAGS are restricted to 23 characters or less.

Log.<log level>("<your package name>", "message");

adb -d logcat <your package name>:<log level> *:S

-d denotes an actual device and -e denotes an emulator. If there's more than 1 emulator running you can use -s emulator-<emulator number> (eg, -s emulator-5558)

Example: adb -d logcat com.example.example:I *:S

Or if you are using System.out.print to send messages to the log you can use adb -d logcat System.out:I *:S to show only calls to System.out.

You can find all the log levels and more info here: https://developer.android.com/studio/command-line/logcat.html

http://developer.android.com/reference/android/util/Log.html

EDIT: Looks like I jumped the gun a little and just realized you were asking about logcat in Eclipse. What I posted above is for using logcat through adb from the command line. I'm not sure if the same filters transfer over into Eclipse.

step 1:

Download dex2jar here. Create a java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

It is matter of performance and memory usage, compile and keep the complied pattern if you need to use it a lot. A typical usage of regex is to validated user input (format), and also format output data for users, in these classes, saving the complied pattern, seems quite logical as they usually called a lot.

Below is a sample validator, which is really called a lot :)

public class AmountValidator {
    //Accept 123 - 123,456 - 123,345.34
    private static final String AMOUNT_REGEX="\\d{1,3}(,\\d{3})*(\\.\\d{1,4})?|\\.\\d{1,4}";
    //Compile and save the pattern  
    private static final Pattern AMOUNT_PATTERN = Pattern.compile(AMOUNT_REGEX);


    public boolean validate(String amount){

         if (!AMOUNT_PATTERN.matcher(amount).matches()) {
            return false;
         }    
        return true;
    }    
}

As mentioned by @Alan Moore, if you have reusable regex in your code, (before a loop for example), you must compile and save pattern for reuse.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

There are some actions which are not working in chrome, inside of the unload event. Alert or confirm boxes are such things.

But what is possible (AFAIK):

1. Open popups (with window.open) - but this will just work, if the popup blocker is disabled for your site
2. Return a simple string (in beforeunload event), which triggers a confirm box, which asks the user if s/he want to leave the page.

Example for #2:

$(window).on('beforeunload', function() {
    return 'Your own message goes here...';
});

2018 here. Use background-size with percentage.

SHEET:

This assumes a single row of sprites. The width of your sheet should be a number that is evenly divisible by 100 + width of one sprite. If you have 30 sprites that are 108x108 px, then add extra blank space to the end to make the final width 5508px (50*108 + 108).

CSS:

.icon{
    height: 30px;  /* Set this to anything. It will scale. */
    width: 30px; /* Match height. This assumes square sprites. */
    background:url(<mysheeturl>);
    background-size: 5100% 100%; /*  5100% because 51 sprites. */
}

/* Each image increases by 2% because we used 50+1 sprites. 
   If we had used 20+1 sprites then % increase would be 5%. */

.first_image{
    background-position: 0% 0;
}

.ninth_image{
    background-position: 16% 0; /* (9-1) x 2 = 16 */
}

HTML:

<div class ="icon first_image"></div>
<div class ="icon ninth_image"></div>

I found two simple approaches that work for me. First, using an already clicked a element and injecting the download data. And second, generating an a element with the download data, executing a.click() and removing it again. But the second approach works only if invoked by a user click action as well. (Some) Browser block click() from other contexts like on loading or triggered after a timeout (setTimeout).

An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture.

Usually, RTSP or HTTP protocol is used by the camera to stream video. An example of IP camera streaming URL is as follows:

rtsp://192.168.1.64/1

It can be opened with OpenCV like this:

capture = cv2.VideoCapture('rtsp://192.168.1.64/1')

Most of the IP cameras have a username and password to access the video. In such case, the credentials have to be provided in the streaming URL as follows:

capture = cv2.VideoCapture('rtsp://username:[email protected]/1')

Mac OS X

I was hoping to find similar information for Mac OS X as well. Since it wasn't here, I went out and dug it up myself. Here are some of the things I found. If anyone has any other suggestions, I'd love to hear them.

Total Virtual Memory

This one is tricky on Mac OS X because it doesn't use a preset swap partition or file like Linux. Here's an entry from Apple's documentation:

Note: Unlike most Unix-based operating systems, Mac OS X does not use a preallocated swap partition for virtual memory. Instead, it uses all of the available space on the machine’s boot partition.

So, if you want to know how much virtual memory is still available, you need to get the size of the root partition. You can do that like this:

struct statfs stats;
if (0 == statfs("/", &stats))
{
    myFreeSwap = (uint64_t)stats.f_bsize * stats.f_bfree;
}

Total Virtual Currently Used

Calling systcl with the "vm.swapusage" key provides interesting information about swap usage:

sysctl -n vm.swapusage
vm.swapusage: total = 3072.00M  used = 2511.78M  free = 560.22M  (encrypted)

Not that the total swap usage displayed here can change if more swap is needed as explained in the section above. So the total is actually the current swap total. In C++, this data can be queried this way:

xsw_usage vmusage = {0};
size_t size = sizeof(vmusage);
if( sysctlbyname("vm.swapusage", &vmusage, &size, NULL, 0)!=0 )
{
   perror( "unable to get swap usage by calling sysctlbyname(\"vm.swapusage\",...)" );
}

Note that the "xsw_usage", declared in sysctl.h, seems not documented and I suspect there there is a more portable way of accessing these values.

Virtual Memory Currently Used by my Process

You can get statistics about your current process using the task_info function. That includes the current resident size of your process and the current virtual size.

#include<mach/mach.h>

struct task_basic_info t_info;
mach_msg_type_number_t t_info_count = TASK_BASIC_INFO_COUNT;

if (KERN_SUCCESS != task_info(mach_task_self(),
                              TASK_BASIC_INFO, (task_info_t)&t_info, 
                              &t_info_count))
{
    return -1;
}
// resident size is in t_info.resident_size;
// virtual size is in t_info.virtual_size;

Total RAM available

The amount of physical RAM available in your system is available using the sysctl system function like this:

#include <sys/types.h>
#include <sys/sysctl.h>
...
int mib[2];
int64_t physical_memory;
mib[0] = CTL_HW;
mib[1] = HW_MEMSIZE;
length = sizeof(int64_t);
sysctl(mib, 2, &physical_memory, &length, NULL, 0);

RAM Currently Used

You can get general memory statistics from the host_statistics system function.

#include <mach/vm_statistics.h>
#include <mach/mach_types.h>
#include <mach/mach_init.h>
#include <mach/mach_host.h>

int main(int argc, const char * argv[]) {
    vm_size_t page_size;
    mach_port_t mach_port;
    mach_msg_type_number_t count;
    vm_statistics64_data_t vm_stats;

    mach_port = mach_host_self();
    count = sizeof(vm_stats) / sizeof(natural_t);
    if (KERN_SUCCESS == host_page_size(mach_port, &page_size) &&
        KERN_SUCCESS == host_statistics64(mach_port, HOST_VM_INFO,
                                        (host_info64_t)&vm_stats, &count))
    {
        long long free_memory = (int64_t)vm_stats.free_count * (int64_t)page_size;

        long long used_memory = ((int64_t)vm_stats.active_count +
                                 (int64_t)vm_stats.inactive_count +
                                 (int64_t)vm_stats.wire_count) *  (int64_t)page_size;
        printf("free memory: %lld\nused memory: %lld\n", free_memory, used_memory);
    }

    return 0;
}

One thing to note here are that there are five types of memory pages in Mac OS X. They are as follows:

1. Wired pages that are locked in place and cannot be swapped out
2. Active pages that are loading into physical memory and would be relatively difficult to swap out
3. Inactive pages that are loaded into memory, but haven't been used recently and may not even be needed at all. These are potential candidates for swapping. This memory would probably need to be flushed.
4. Cached pages that have been some how cached that are likely to be easily reused. Cached memory probably would not require flushing. It is still possible for cached pages to be reactivated
5. Free pages that are completely free and ready to be used.

It is good to note that just because Mac OS X may show very little actual free memory at times that it may not be a good indication of how much is ready to be used on short notice.

RAM Currently Used by my Process

See the "Virtual Memory Currently Used by my Process" above. The same code applies.

You are right that greediness is an issue:

--A--Z--A--Z--
  ^^^^^^^^^^
     A.*Z

If you want to match both A--Z, you'd have to use A.*?Z (the ? makes the * "reluctant", or lazy).

There are sometimes better ways to do this, though, e.g.

A[^Z]*+Z

This uses negated character class and possessive quantifier, to reduce backtracking, and is likely to be more efficient.

In your case, the regex would be:

/(\[[^\]]++\])/

Unfortunately Javascript regex doesn't support possessive quantifier, so you'd just have to do with:

/(\[[^\]]+\])/

See also

• regular-expressions.info/Repetition
  • See: An Alternative to Laziness
    • Possessive quantifiers
  • Flavors comparison

Quick summary

*   Zero or more, greedy
*?  Zero or more, reluctant
*+  Zero or more, possessive

+   One or more, greedy
+?  One or more, reluctant
++  One or more, possessive

?   Zero or one, greedy
??  Zero or one, reluctant
?+  Zero or one, possessive

Note that the reluctant and possessive quantifiers are also applicable to the finite repetition {n,m} constructs.

Examples in Java:

System.out.println("aAoZbAoZc".replaceAll("A.*Z", "!"));  // prints "a!c"
System.out.println("aAoZbAoZc".replaceAll("A.*?Z", "!")); // prints "a!b!c"

System.out.println("xxxxxx".replaceAll("x{3,5}", "Y"));  // prints "Yx"
System.out.println("xxxxxx".replaceAll("x{3,5}?", "Y")); // prints "YY"

Think of HTTP as a person(A) who has SHORT TERM MEMORY LOSS and forgets every person as soon as that person goes out of sight.

Now, to remember different persons, A takes a photo of that person and keeps it. Each Person's pic has an ID number. When that person comes again in sight, that person tells it's ID number to A and A finds their picture by ID number. And voila !!, A knows who is that person.

Same is with HTTP. It is suffering from SHORT TERM MEMORY LOSS. It uses Sessions to record everything you did while using a website, and then, when you come again, it identifies you with the help of Cookies(Cookie is like a token). Picture is the Session here, and ID is the Cookie here.

To complement the existing helpful answers:

Using Bash's own regex-matching operator, =~, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:

set -- '12-34-5678' # set $1 to sample value

kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match

Note, however, that the caveat re using flavor-specific regex constructs such as \d equally applies: While =~ supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.

To remain portable (in the context of Bash), stick to the POSIX ERE specification.

Note that =~ even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]} array variable.

Further notes:

• $kREGEX_DATE is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).

• While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \.

  • E.g., on Linux, where \< is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes does.

• I've changed variable name REGEX_DATE to kREGEX_DATE (k signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.

I had the same problems in two machines: Win8.1x64 with Visual Studio Ultimate 2013 (VS2013) and Win8x64 with VS2013 ultimate

Problem: Shortcut "VS2012 x86 Native Tools Command Prompt" which points to file: C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat which calls C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\vcvars32.bat tries to search the registry for value name "11.0":

reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "11.0"

However my machine doesn't have this value "11.0", instead it has "12.0"

My solution is to run C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\vcvarsall.bat which calls C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\bin\vcvars32.bat which correctly query the registry as the following:

reg query "%1\SOFTWARE\Microsoft\VisualStudio\SxS\VS7" /v "12.0"

So changing/running from C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat to C:\Program Files (x86)\ Microsoft Visual Studio 12.0 \VC\vcvarsall.bat solved it in my case

So, something like the $_POST array?

You can use http_build_query($_POST) to get them in a var=xxx&var2=yyy string again. Or just print_r($_POST) to see what's there.

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

It's very easy:

numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
   if numb == lines[0]:
      print lines

It is possible to connect to the database without specifying a password. Once you've done that you can then reset the passwords. I'm assuming that you've installed the database on your machine; if not you'll first need to connect to the machine the database is running on.

1. Ensure your user account is a member of the dba group. How you do this depends on what OS you are running.

2. Enter sqlplus / as sysdba in a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.

3. Once you're logged in, you can then enter

   alter user SYS identified by "newpassword";
   

   to reset the SYS password, and similarly for SYSTEM.

(Note: I haven't tried any of this on Oracle 12c; I'm assuming they haven't changed things since Oracle 11g.)

November 2020 Update

I searched for the top NodeJS html parser libraries.

Because my use cases didn't require a library with many features, I could focus on stability and performance.

By stability I mean that I want the library to be used long enough by the community in order to find bugs and that it will be still maintained and that open issues will be closed.

Its hard to understand the future of an open source library, but I did a small summary based on the top 10 libraries in openbase.

I divided into 2 groups according to the last commit (and on each group the order is according to Github starts):

Last commit is in the last 6 months:

jsdom - Last commit: 3 Months, Open issues: 331, Github stars: 14.9K.

htmlparser2 - Last commit: 8 days, Open issues: 2, Github stars: 2.7K.

parse5 - Last commit: 2 Months, Open issues: 21, Github stars: 2.5K.

swagger-parser - Last commit: 2 Months, Open issues: 48, Github stars: 663.

html-parse-stringify - Last commit: 4 Months, Open issues: 3, Github stars: 215.

node-html-parser - Last commit: 7 days, Open issues: 15, Github stars: 205.

Last commit is 6 months and above:

cheerio - Last commit: 1 year, Open issues: 174, Github stars: 22.9K.

koa-bodyparser - Last commit: 6 months, Open issues: 9, Github stars: 1.1K.

sax-js - Last commit: 3 Years, Open issues: 65, Github stars: 941.

draftjs-to-html - Last commit: 1 Year, Open issues: 27, Github stars: 233.

I picked Node-html-parser because it seems quiet fast and very active at this moment.

(*) Openbase adds much more information regarding each library like the number of contributors (with +3 commits), weekly downloads, Monthly commits, Version etc'.

(**) The table above is a snapshot according to the specific time and date - I would check the reference again and as a first step check the level of recent activity and then dive into the smaller details.

Here is the R version of b-h-'s function, just in case:

measure <- function(lon1,lat1,lon2,lat2) {
    R <- 6378.137                                # radius of earth in Km
    dLat <- (lat2-lat1)*pi/180
    dLon <- (lon2-lon1)*pi/180
    a <- sin((dLat/2))^2 + cos(lat1*pi/180)*cos(lat2*pi/180)*(sin(dLon/2))^2
    c <- 2 * atan2(sqrt(a), sqrt(1-a))
    d <- R * c
    return (d * 1000)                            # distance in meters
}

I have tried the awnsers before but this did not work. Now I jsut used a LinearLayout instead of a TextureView, now it is working without any problem. Hope it helps some others who have the same problem. :)

    view = (LinearLayout) findViewById(R.id.view); //this is initialized in the constructor
    openWindowOnButtonClick();

public void openWindowOnButtonClick()
{
    view.setAlpha((float)0.5);
    FloatingActionButton fb = (FloatingActionButton) findViewById(R.id.floatingActionButton);
    final InputMethodManager keyboard = (InputMethodManager) getSystemService(getBaseContext().INPUT_METHOD_SERVICE);
    fb.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // check if the Overlay should be visible. If this value is false, it is not shown -> show it.
            if(view.getVisibility() == View.INVISIBLE)
            {
                view.setVisibility(View.VISIBLE);
                keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
                Log.d("Overlay", "Klick");
            }
            else if(view.getVisibility() == View.VISIBLE)
            {
                view.setVisibility(View.INVISIBLE);
                keyboard.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
            }

<style>
.form-error {
        border: 2px solid #e74c3c;
    }
</style>



<div class="form-error">
                                {!! Form::select('color', $colors->prepend('Please Select Color', ''),           ,['class' => 'form-control dropselect form-error'
                                ,'tabindex' => $count++, 'id' => 'color']) !!}
                                </div>

When I need to chain calls like that, I rely on a helper method I created, TryGet():

    public static U TryGet<T, U>(this T obj, Func<T, U> func)
    {
        return obj.TryGet(func, default(U));
    }

    public static U TryGet<T, U>(this T obj, Func<T, U> func, U whenNull)
    {
        return obj == null ? whenNull : func(obj);
    }

In your case, you would use it like so:

    int value = ObjectA
        .TryGet(p => p.PropertyA)
        .TryGet(p => p.PropertyB)
        .TryGet(p => p.PropertyC, defaultVal);

Another option is to use GNU seq and remove all numbers and newlines it generates:

seq -f'#%.0f' 100 | tr -d '\n0123456789'

This command prints the # character 100 times.

I just tried doing this on Chrome:

var $sel = $('#sel'); $sel.find('option').hover(function(){$sel.attr('title',$(this).attr('title'));console.log($(this).attr('title'))}, function(){$sel.attr('title','');});

However, the hover enter never fires... So you wouldn't be able to do this at all using the standard select. You could achieve this though through some non standard ways:

• You could fake a select box by using radio boxes that look like dropdowns. So for example, have a radio box absolute positioned and opacity set to 0 placed over the styled box that is pretending to be the option.
• Or you could use pure javascript and have a series of boxes and adding javascript onclick events to recreate the dropbox yourself - so you will update a hidden value with whichever box was clicked using javascript.
• Or use one of the non standard libraries already out there. (If there are any?)

Here is an option. This is just for the x coordinates.

var div1Pos = $("#div1").offset();
var div1X = div1Pos.left;
$('#div2').css({left: div1X});

I can't believe that in all this time, no one has mentioned:

sudo lshw -class cpu

to get details about the speed, quantity, size and capabilities of the CPU hardware.

Old question, but thought I'd add this to help out,

#if DOTNET35
bool isTrulyEmpty = String.IsNullOrEmpty(s) || s.Trim().Length == 0;
#else
bool isTrulyEmpty = String.IsNullOrWhiteSpace(s) ;
#endif

You can select to an anonymous type, for example

var dataset2 = 
    (from recordset in entities.processlists 
    where recordset.ProcessName == processname 
    select new
    {
        serverName = recordset.ServerName,
        processId = recordset.ProcessID, 
        username = recordset.Username
    }).ToList();

Or you can create a new class that will represent your selection, for example

public class MyDataSet
{
    public string ServerName { get; set; }
    public string ProcessId { get; set; }
    public string Username { get; set; }
}

then you can for example do the following

 var dataset2 = 
    (from recordset in entities.processlists 
    where recordset.ProcessName == processname 
    select new MyDataSet
    {
        ServerName = recordset.ServerName,
        ProcessId = recordset.ProcessID, 
        Username = recordset.Username
    }).ToList();

try this:

    @System.Web.Optimization.Styles.Render("~/Content/css")
    @System.Web.Optimization.Scripts.Render("~/bundles/modernizr")

It worked to me. I'm still learning, and I've not figured it out yet why it is happening

You may try to install Package Control first by following simple instructions available at Installation Guide (which is like 1. Open the Console, 2. Paste the code).

Then please check Package Docs Control Usage for Basic Functionality:

Package Control is driven by the Command Pallete. To open the pallete, press Ctrl+Shift+P (Win, Linux) or CMD+Shift+P (OS X). All Package Control commands begin with Package Control:, so start by typing Package.

The command pallete will now show a number of commands. Most users will be interested in the following:

Install Package

Show a list of all available packages that are available for install. This will include all of the packages from the default channel, plus any from repositories you have added.

You are probably looking for get_attribute(). An example is shown here as well

def test_chart_renders_from_url(self):
    url = 'http://localhost:8000/analyse/'
    self.browser.get(url)
    org = driver.find_element_by_id('org')
    # Find the value of org?
    val = org.get_attribute("attribute name")

Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:

<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}

which works just fine as well.

I use this script to delete last 10 commands in history:

pos=$HISTCMD; start=$(( $pos-11 )); end=$(( $pos-1 )); for i in $(eval echo "{${start}..${end}}"); do history -d $start; done

It uses $HISTCMD environment var to get the history index and uses that to delete last 10 entries in history.

I want some code to run in the background continuously. I don't want to do it in a service. Is there any other way possible?

Most likely mechanizm that you are looking for is AsyncTask. It directly designated for performing background process on background Thread. Also its main benefit is that offers a few methods which run on Main(UI) Thread and make possible to update your UI if you want to annouce user about some progress in task or update UI with data retrieved from background process.

If you don't know how to start here is nice tutorial:

• Understanding AsyncTask – Once and Forever

Note: Also there is possibility to use IntentService with ResultReceiver that works as well.

You will have the same object two times in your array, because object values are passed by reference. You have to create a new object like this

myElement.id = 244;
myElement.value = 3556;
myArray[0] = $.extend({}, myElement); //for shallow copy or
myArray[0] = $.extend(true, {}, myElement); // for deep copy

or

myArray.push({ id: 24, value: 246 });
