My alternative solution to using Valgrind:

I'm very happy because I just helped my friend debug a program. His program had this exact problem (malloc() causing abort), with the same error message from GDB.

I compiled his program using Address Sanitizer with

gcc -Wall -g3 -fsanitize=address -o new new.c
              ^^^^^^^^^^^^^^^^^^

And then ran gdb new. When the program gets terminated by SIGABRT caused in a subsequent malloc(), a whole lot of useful information is printed:

=================================================================
==407==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6060000000b4 at pc 0x7ffffe49ed1a bp 0x7ffffffedc20 sp 0x7ffffffed3c8

Let's take a look at the output, especially the stack trace:

The first part says there's a invalid write operation at new.c:59. That line reads

memset(len,0,sizeof(int*)*p);
             ^^^^^^^^^^^^

The second part says the memory that the bad write happened on is created at new.c:55. That line reads

if(!(len=(int*)malloc(sizeof(int)*p))){
                      ^^^^^^^^^^^

That's it. It only took me less than half a minute to locate the bug that confused my friend for a few hours. He managed to locate the failure, but it's a subsequent malloc() call that failed, without being able to spot this error in previous code.

Sum up: Try the -fsanitize=address of GCC or Clang. It can be very helpful when debugging memory issues.

If you want to do this, you need to save it in a variable first. So you don't need to use id to query this element every time.

var el = $("#page_navigation1");

$("#add").click(function(){
  el.attr("id","page_navigation1");
});     

$("#remove").click(function(){
  el.removeAttr("id");
});     

I tried what Samuel Slade has suggested. Didn't work for me. The PropertyInfo list was coming as empty. So, I tried the following and it worked for me.

    Type type = typeof(Record);
    FieldInfo[] properties = type.GetFields();
    foreach (FieldInfo property in properties) {
       Debug.LogError(property.Name);
    }

You should try to use:

echo "scale=4;$variablename/3"|bc

Here's how to disable minification on a per-bundle basis:

bundles.Add(new StyleBundleRaw("~/Content/foobarcss").Include("/some/path/foobar.css"));
bundles.Add(new ScriptBundleRaw("~/Bundles/foobarjs").Include("/some/path/foobar.js"));

Sidenote: The paths used for your bundles must not coincide with any actual path in your published builds otherwise nothing will work. Also make sure to avoid using .js, .css and/or '.' and '_' anywhere in the name of the bundle. Keep the name as simple and as straightforward as possible, like in the example above.

The helper classes are shown below. Notice that in order to make these classes future-proof we surgically remove the js/css minifying instances instead of using .clear() and we also insert a mime-type-setter transformation without which production builds are bound to run into trouble especially when it comes to properly handing over css-bundles (firefox and chrome reject css bundles with mime-type set to "text/html" which is the default):

internal sealed class StyleBundleRaw : StyleBundle
{
        private static readonly BundleMimeType CssContentMimeType = new BundleMimeType("text/css");

        public StyleBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
        {
        }

        public StyleBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
        {
                 Transforms.Add(CssContentMimeType); //0 vital
                 Transforms.Remove(Transforms.FirstOrDefault(x => x is CssMinify)); //0
        }
        //0 the guys at redmond in their infinite wisdom plugged the mimetype "text/css" right into cssminify    upon unwiring the minifier we
        //  need to somehow reenable the cssbundle to specify its mimetype otherwise it will advertise itself as html and wont load
}

internal sealed class ScriptBundleRaw : ScriptBundle
{
        private static readonly BundleMimeType JsContentMimeType = new BundleMimeType("text/javascript");

        public ScriptBundleRaw(string virtualPath) : this(virtualPath, cdnPath: null)
        {
        }

        public ScriptBundleRaw(string virtualPath, string cdnPath) : base(virtualPath, cdnPath)
        {
                 Transforms.Add(JsContentMimeType); //0 vital
                 Transforms.Remove(Transforms.FirstOrDefault(x => x is JsMinify)); //0
        }
        //0 the guys at redmond in their infinite wisdom plugged the mimetype "text/javascript" right into jsminify   upon unwiring the minifier we need
        //  to somehow reenable the jsbundle to specify its mimetype otherwise it will advertise itself as html causing it to be become unloadable by the browsers in published production builds
}

internal sealed class BundleMimeType : IBundleTransform
{
        private readonly string _mimeType;

        public BundleMimeType(string mimeType) { _mimeType = mimeType; }

        public void Process(BundleContext context, BundleResponse response)
        {
                 if (context == null)
                          throw new ArgumentNullException(nameof(context));
                 if (response == null)
                          throw new ArgumentNullException(nameof(response));

         response.ContentType = _mimeType;
        }
}

To make this whole thing work you need to install (via nuget):

WebGrease 1.6.0+ Microsoft.AspNet.Web.Optimization 1.1.3+

And your web.config should be enriched like so:

Note that you might have to take extra steps to make your css-bundles work in terms of fonts etc. But that's a different story.

Public Function RandomNumber(ByVal n As Integer) As Integer
    'initialize random number generator
    Dim r As New Random(System.DateTime.Now.Millisecond)
    Return r.Next(1, n)
End Function

It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.

Suppose your select has 10 option, then fixed size=9.

Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.

Here is your modified code from jsfiddle:

<select size="5" style="width:100px;">
 <option>1</option>
 <option>2</option>
 <option>3</option>
 <option>4</option>
 <option>5</option>
 <option>6</option>
</select>

this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).

Here is your desired result. I think this will help you:

CSS

  .wrapper{
    border: 1px dashed red;
    height: 150px;
    overflow-x: hidden;
    overflow-y: scroll;
    width: 150px;
 }
 .wrapper .selection{
   width:150px;
   border:1px solid #ccc
 }

HTML

<div class="wrapper">
<select size="15" class="selection">
    <option>Item 1</option>
    <option>Item 2</option>
    <option>Item 3</option>
</select>
</div>

the dictionary

d = {1:2, 3:4, 5:6, 7:8}

the subset of keys I'm interested in

l = (1,5)

answer

{key: d[key] for key in l}

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

from an activity you can do:

getWindow().setStatusBarColor(i color);

Another approach to return a value from an asynchronous function, is to pass in an object that will store the result from the asynchronous function.

Here is an example of the same:

var async = require("async");

// This wires up result back to the caller
var result = {};
var asyncTasks = [];
asyncTasks.push(function(_callback){
    // some asynchronous operation
    $.ajax({
        url: '...',
        success: function(response) {
            result.response = response;
            _callback();
        }
    });
});

async.parallel(asyncTasks, function(){
    // result is available after performing asynchronous operation
    console.log(result)
    console.log('Done');
});

I am using the result object to store the value during the asynchronous operation. This allows the result be available even after the asynchronous job.

I use this approach a lot. I would be interested to know how well this approach works where wiring the result back through consecutive modules is involved.

CGSize expectedLabelSize = [yourString sizeWithFont:yourLabel.font 
                        constrainedToSize:maximumLabelSize 
                        lineBreakMode:yourLabel.lineBreakMode]; 

What is -[NSString sizeWithFont:forWidth:lineBreakMode:] good for?

this question might have your answer, it worked for me.

For 2014, I edited in this new version, based on the ultra-handy comment by Norbert below! This does everything. Cheers

// yourLabel is your UILabel.

float widthIs = 
 [self.yourLabel.text
  boundingRectWithSize:self.yourLabel.frame.size                                           
  options:NSStringDrawingUsesLineFragmentOrigin
  attributes:@{ NSFontAttributeName:self.yourLabel.font }
  context:nil]
   .size.width;

NSLog(@"the width of yourLabel is %f", widthIs);

For those who use Tomcat with Bitronix, this will fix the problem:

The error indicates that no handler could be found for your datasource 'jdbc/mydb', so you'll need to make sure your tomcat server refers to your bitronix configuration files as needed.

In case you're using btm-config.properties and resources.properties files to configure the datasource, specify these two JVM arguments in tomcat:

(if you already used them, make sure your references are correct):

• btm.root
• bitronix.tm.configuration

e.g.

-Dbtm.root="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59" 
-Dbitronix.tm.configuration="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59\conf\btm-config.properties" 

Now, restart your server and check the log.

Put this on an event

$(function(){
    $('.package').click(function(){
       var content = $('.container').html();
       $(this).html(content);
    });
});

For many years I used the command:

ps aux | grep postgres

On one hand it is useful (for any process) and gives useful info (but from process POV). But on the other hand it is for checking if the server you know, you already installed is running.

At some point I found this tutorial, where the usage of the locate command is shown. It looks like this command is much more to the point for this case.

Select all the data and use the option "Text to Columns", that will allow your data for Applying Number Formatting ERIK

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

You can use the new request method getSchemeAndHttpHost():

{{ app.request.getSchemeAndHttpHost() }}

For unlimited memory limit set -1 in memory_limit variable:

ini_set('memory_limit', '-1');

To get rid of symbol warnings you don't want, first you should understand how Eclipse CDT normally comes up with unknown symbol warnings in the first place. This is its process, more or less:

1. Eclipse detects the GCC toolchains available on the system
2. Your Eclipse project is configured to use a particular toolchain
3. Eclipse does discovery on the toolchain to find its include paths and built-in defines, i.e. by running it with relevant options and reading the output
4. Eclipse reads the header files from the include paths
5. Eclipse indexes the source code in your project
6. Eclipse shows warnings about unresolved symbols in the editor

It might be better in the long run to fix problems with the earlier steps rather than to override their results by manually adding include directories, symbols, etc.

Toolchains

If you have GCC installed, and Eclipse has detected it, it should list that GCC as a toolchain choice that a new C++ project could use, which will also show up in Window -> Preferences -> C/C++ -> New CDT Project Wizard on the Preferred Toolchains tab's Toolchains box on the right side. If it's not showing up, see the CDT FAQ's answer about compilers that need special environments (as well as MinGW and Cygwin answers for the Windows folk.)

If you have an existing Eclipse C++ project, you can change the associated toolchain by opening the project properties, and going to C/C++ Build -> Tool Chain Editor and choosing the toolchain you want from the Current toolchain: pulldown. (You'll have to uncheck the Display compatible toolchains only box first if the toolchain you want is different enough from the one that was previously set in the project.)

If you added a toolchain to the system after launching Eclipse, you will need to restart it for it to detect the toolchain.

Discovery

Then, if the project's C/C++ Build -> Discovery Options -> Discovery profiles scope is set to Per Language, during the next build the new toolchain associated with the project will be used for auto-discovery of include paths and symbols, and will be used to update the "built-in" paths and symbols that show up in the project's C/C++ General -> Paths and Symbols in the Includes and Symbols tabs.

Indexing

Sometimes you need to re-index again after setting the toolchain and doing a build to get the old symbol warnings to go away; right-click on the project folder and go to Index -> Rebuild to do it.

(tested with Eclipse 3.7.2 / CDT 8)

p.s. I didn't want to take the liberty of modifying @cwallenpoole's answer to reflect the fact that this is a MySQL question and not an Oracle question and doesn't need DUAL.

You paste this inside :

1. Best answer based on my assessment:

The answer by @Adisak is the best answer here based on my assessment. Note that this answer is in part the best because it is also the _most well-backed-up with real code examples, in addition to using sound and well-thought-out logic._

2. My own words (agreeing with the best answer):

1. For pass-by-value there is no benefit to adding const. All it does is:
   1. limit the implementer to have to make a copy every time they want to change an input param in the source code (which change would have no side effects anyway since what's passed in is already a copy since it's pass-by-value). And frequently, changing an input param which is passed by value is used to implement the function, so adding const everywhere can hinder this.
   2. and adding const unnecessarily clutters the code with consts everywhere, drawing attention away from the consts that are truly necessary to have safe code.
2. When dealing with pointers or references, however, const is critically important when needed, and must be used, as it prevents undesired side effects with persistent changes outside the function, and therefore every single pointer or reference must use const when the param is an input only, not an output. Using const only on parameters passed by reference or pointer has the additional benefit of making it really obvious which parameters are pointers or references. It's one more thing to stick out and say "Watch out! Any param with const next to it is a reference or pointer!".
3. What I've described above has frequently been the consensus achieved in professional software organizations I have worked in, and has been considered best practice. Sometimes even, the rule has been strict: "don't ever use const on parameters which are passed by value, but always use it on parameters passed by reference or pointer if they are inputs only."

3. Google's words (agreeing with me and the best answer):

(From the "Google C++ Style Guide")

For a function parameter passed by value, const has no effect on the caller, thus is not recommended in function declarations. See TotW #109.

Using const on local variables is neither encouraged nor discouraged.

Source: the "Use of const" section of the Google C++ Style Guide: https://google.github.io/styleguide/cppguide.html#Use_of_const. This is actually a really valuable section, so read the whole section.

Note that "TotW #109" stands for "Tip of the Week #109: Meaningful const in Function Declarations", and is also a useful read. It is more informative and less prescriptive on what to do, and based on context came before the Google C++ Style Guide rule on const quoted just above, but as a result of the clarity it provided, the const rule quoted just above was added to the Google C++ Style Guide.

Also note that even though I'm quoting the Google C++ Style Guide here in defense of my position, it does NOT mean I always follow the guide or always recommend following the guide. Some of the things they recommend are just plain weird, such as their kDaysInAWeek-style naming convention for "Constant Names". However, it is still nonetheless useful and relevant to point out when one of the world's most successful and influential technical and software companies uses the same justification as I and others like @Adisak do to back up our viewpoints on this matter.

4. Clang's linter, clang-tidy, has some options for this:

A. It's also worth noting that Clang's linter, clang-tidy, has an option, readability-avoid-const-params-in-decls, described here, to support enforcing in a code base not using const for pass-by-value function parameters:

Checks whether a function declaration has parameters that are top level const.

const values in declarations do not affect the signature of a function, so they should not be put there.

Examples:

void f(const string);   // Bad: const is top level.
void f(const string&);  // Good: const is not top level.

And here are two more examples I'm adding myself for completeness and clarity:

void f(char * const c_string);   // Bad: const is top level. [This makes the _pointer itself_, NOT what it points to, const]
void f(const char * c_string);   // Good: const is not top level. [This makes what is being _pointed to_ const]

B. It also has this option: readability-const-return-type - https://clang.llvm.org/extra/clang-tidy/checks/readability-const-return-type.html

5. My pragmatic approach to how I'd word a style guide on the matter:

I'd simply copy and paste this into my style guide:

[COPY/PASTE START]

1. Always use const on function parameters passed by reference or pointer when their contents (what they point to) are intended NOT to be changed. This way, it becomes obvious when a variable passed by reference or pointer IS expected to be changed, because it will lack const. In this use case const prevents accidental side effects outside the function.
2. It is not recommended to use const on function parameters passed by value, because const has no effect on the caller: even if the variable is changed in the function there will be no side effects outside the function. See the following resources for additional justification and insight:
   1. "Google C++ Style Guide" "Use of const" section
   2. "Tip of the Week #109: Meaningful const in Function Declarations"
   3. Adisak's Stack Overflow answer on "Use of 'const' for function parameters"
3. "Never use top-level const [ie: const on parameters passed by value] on function parameters in declarations that are not definitions (and be careful not to copy/paste a meaningless const). It is meaningless and ignored by the compiler, it is visual noise, and it could mislead readers" (https://abseil.io/tips/109, emphasis added).
4. The only const qualifiers that have an effect on compilation are those placed in the function definition, NOT those in a forward declaration of the function, such as in a function (method) declaration in a header file.
5. Never use top-level const [ie: const on variables passed by value] on values returned by a function.
6. Using const on pointers or references returned by a function is up to the implementer, as it is sometimes useful.
7. TODO: enforce some of the above with the following clang-tidy options:
8. https://clang.llvm.org/extra/clang-tidy/checks/readability-avoid-const-params-in-decls.html
9. https://clang.llvm.org/extra/clang-tidy/checks/readability-const-return-type.html

Here are some code examples to demonstrate the const rules described above:

const Parameter Examples:
(some are borrowed from here)

void f(const std::string);   // Bad: const is top level.
void f(const std::string&);  // Good: const is not top level.

void f(char * const c_string);   // Bad: const is top level. [This makes the _pointer itself_, NOT what it points to, const]
void f(const char * c_string);   // Good: const is not top level. [This makes what is being _pointed to_ const]

const Return Type Examples:
(some are borrowed from here)

// BAD--do not do this:
const int foo();
const Clazz foo();
Clazz *const foo();

// OK--up to the implementer:
const int* foo();
const int& foo();
const Clazz* foo();

[COPY/PASTE END]

if i want to check if any speicfic position of command line arguement is passed or not then how to check? like for example in some scenarios 2 command line args will be passed and in some only one will be passed then how do it check wheather the specfic commnad line is passed or not?

public class check {

public static void main(String[] args) {
if(args[0].length()!=0)
{
System.out.println("entered first if");
}
if(args[0].length()!=0 && args[1].length()!=0)
{
System.out.println("entered second if");
}
}
}

So in the above code if args[1] is not passed then i get java.lang.ArrayIndexOutOfBoundsException:

so how do i tackle this where i can check if second arguement is passed or not and if passed then enter it. need assistance asap.

There are several issues in your code :

• You are handling the click event of a submit button, whose default behavior is to post a request to the server and reload the page. You have to inhibit this behavior by returning false from your handler:

  onclick="SubmitFrm(); return false;"
  

• value cannot be called because it is a property, not a method:

  var Searchtxt = document.getElementById("txtSearch").value;
  

• The search query you are sending in the query string has to be encoded:

  window.location = "http://www.mysite.com/search/?Query="
      + encodeURIComponent(Searchtxt);
  

John Feminella's solution has a bug.

At the line

if (A[i] + A[j] + A[k] == 0) return (A[i], A[j], A[k])

We need to check if i,j,k are all distinct. Otherwise, if my target element is 6 and if my input array contains {3,2,1,7,9,0,-4,6} . If i print out the tuples that sum to 6, then I would also get 0,0,6 as output . To avoid this, we need to modify the condition in this way.

if ((A[i] + A[j] + A[k] == 0) && (i!=j) && (i!=k) && (j!=k)) return (A[i], A[j], A[k])

You can't save things to Hibernate until you've also told Hibernate about all the other objects referenced by this newly saved object. So in this case, you're telling Hibernate about a User, but haven't told it about the Country.

You can solve problems like this in two ways.

Manually

Call session.save(country) before you save the User.

CascadeType

You can specify to Hibernate that this relationship should propagate some operations using CascadeType. In this case CascadeType.PERSIST would do the job, as would CascadeType.ALL.

Referencing existing countries

Based on your response to @zerocool though, you have a second problem, which is that when you have two User objects with the same Country, you are not making sure it's the same Country. To do this, you have to get the appropriate Country from the database, set it on the new user, and then save the User. Then, both of your User objects will refer to the same Country, not just two Country instances that happen to have the same name. Review the Criteria API as one way of fetching existing instances.

The Ruby File class will give you the ins and outs of ::new and ::open but its parent, the IO class, gets into the depth of #read and #write.

window.navigate not supported in some browser

In java script many ways are there for redirection, see the below code and explanation

window.location.href = "http://krishna.developerstips.com/";
window.location = "http://developerstips.com/";
window.location.replace("http://developerstips.com/");
window.location.assign("http://work.developerstips.com/");

window.location.href loads page from browser's cache and does not always send the request to the server. So, if you have an old version of the page available in the cache then it will redirect to there instead of loading a fresh page from the server.

window.location.assign() method for redirection if you want to allow the user to use the back button to go back to the original document.

window.location.replace() method if you want to want to redirect to a new page and don't allow the user to navigate to the original page using the back button.

The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0^{[Ref 1]}.
The second is more readable.

The choice depends on user preference or the one which your coding standard mandates.

^{[Ref 1]} Reference C99 Standard 6.7.8.21:

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

<script type="text/javascript">

    $('#upload').on('change',function(){
       // output raw value of file input
       $('#filename').html($(this).val().replace(/.*(\/|\\)/, '')); 

        // or, manipulate it further with regex etc.
        var filename = $(this).val().replace(/.*(\/|\\)/, '');
        // .. do your magic

        $('#filename').html(filename);
    });
</script>

This functionality is now supported by Python 3.8+ :)

I had missed another tiny detail: I forgot the brackets "(100)" behind NVARCHAR.

You first Perl example doesn't look unreasonable to me.

It's for reasons like this that I migrated from writing shell scripts (in bash/sh etc.) to writing all but the most trivial scripts in Perl. I found that I was having to launch Perl for particular requirements, and as I did that more and more, I realised that writing the scripts in Perl was probably a more powerful (in terms of the language and the wide array of libraries available via CPAN) and more efficient way to achieve what I wanted.

Note that other shell-scripting languages (e.g. python/ruby) will no doubt have similar facilities, and you may want to evaluate these for your purposes. I only discuss Perl since that's the language I use and am familiar with.

git checkout has the --ours option to check out the version of the file that you had locally (as opposed to --theirs, which is the version that you pulled in). You can pass . to git checkout to tell it to check out everything in the tree. Then you need to mark the conflicts as resolved, which you can do with git add, and commit your work once done:

git checkout --ours .  # checkout our local version of all files
git add -u             # mark all conflicted files as merged
git commit             # commit the merge

Note the . in the git checkout command. That's very important, and easy to miss. git checkout has two modes; one in which it switches branches, and one in which it checks files out of the index into the working copy (sometimes pulling them into the index from another revision first). The way it distinguishes is by whether you've passed a filename in; if you haven't passed in a filename, it tries switching branches (though if you don't pass in a branch either, it will just try checking out the current branch again), but it refuses to do so if there are modified files that that would effect. So, if you want a behavior that will overwrite existing files, you need to pass in . or a filename in order to get the second behavior from git checkout.

It's also a good habit to have, when passing in a filename, to offset it with --, such as git checkout --ours -- <filename>. If you don't do this, and the filename happens to match the name of a branch or tag, Git will think that you want to check that revision out, instead of checking that filename out, and so use the first form of the checkout command.

I'll expand a bit on how conflicts and merging work in Git. When you merge in someone else's code (which also happens during a pull; a pull is essentially a fetch followed by a merge), there are few possible situations.

The simplest is that you're on the same revision. In this case, you're "already up to date", and nothing happens.

Another possibility is that their revision is simply a descendent of yours, in which case you will by default have a "fast-forward merge", in which your HEAD is just updated to their commit, with no merging happening (this can be disabled if you really want to record a merge, using --no-ff).

Then you get into the situations in which you actually need to merge two revisions. In this case, there are two possible outcomes. One is that the merge happens cleanly; all of the changes are in different files, or are in the same files but far enough apart that both sets of changes can be applied without problems. By default, when a clean merge happens, it is automatically committed, though you can disable this with --no-commit if you need to edit it beforehand (for instance, if you rename function foo to bar, and someone else adds new code that calls foo, it will merge cleanly, but produce a broken tree, so you may want to clean that up as part of the merge commit in order to avoid having any broken commits).

The final possibility is that there's a real merge, and there are conflicts. In this case, Git will do as much of the merge as it can, and produce files with conflict markers (<<<<<<<, =======, and >>>>>>>) in your working copy. In the index (also known as the "staging area"; the place where files are stored by git add before committing them), you will have 3 versions of each file with conflicts; there is the original version of the file from the ancestor of the two branches you are merging, the version from HEAD (your side of the merge), and the version from the remote branch.

In order to resolve the conflict, you can either edit the file that is in your working copy, removing the conflict markers and fixing the code up so that it works. Or, you can check out the version from one or the other sides of the merge, using git checkout --ours or git checkout --theirs. Once you have put the file into the state you want it, you indicate that you are done merging the file and it is ready to commit using git add, and then you can commit the merge with git commit.

Its a common error which happens when we try to access a database which doesn't exist. So create the database using

CREATE DATABASE blog_development;

The error commonly occours when we have dropped the database using

DROP DATABASE blog_development;

and then try to access the database.

I do it like this:

CREATE UNIQUE INDEX index_name ON TableName (Column1, Column2, Column3);

My convention for a unique index_name is TableName_Column1_Column2_Column3_uindex.

This question is not new and existing answers give some good theoretical background. I just want to add a more pragmatic answer.

getText is a method of the Context abstract class and in order to call it, one needs an instance of it's subclass (Activity, Service, Application or other). The problem is, that the public static final variables are initialized before any instance of Context is created.

There are several ways to solve this:

1. Make the variable a member variable (field) of the Activity or other subclass of Context by removing the static modifier and placing it within the class body;
2. Keep it static and delay the initialization to a later point (e.g. in the onCreate method);
3. Make it a local variable in the place of actual usage.

In Python 3, print is a function, whereas it used to be a statement in previous versions. As @holdenweb suggested, use 2to3 to translate your code.

Taken from the accepted answers comment by Steve on Dec 20, 2013:

Actually, there's a very easy way to do it: just click off "Block popup windows" in the iMac/Safari browser and it does what I want.

To clarify, when running Safari on Mac OS X El Capitan:

1. Safari -> Preferences
2. Security -> Uncheck 'Block pop-up windows'

const countryResolver = (data = [{}]) => {
    const countrySelecter = document.createElement('select');
    countrySelecter.className = `custom-select`;
    countrySelecter.id = `countrySelect`;
    countrySelecter.setAttribute("aria-label", "Example select with button addon");

    let opt = document.createElement("option");
    opt.text = "Select language";
    opt.disabled = true;
    countrySelecter.add(opt, null);
    let i = 0;
    for (let item of data) {
        let opt = document.createElement("option");
        opt.value = item.Id;
        opt.text = `${i++}. ${item.Id} - ${item.Value}(${item.Comment})`;
        countrySelecter.add(opt, null);
    }
    return countrySelecter;
};

public class HelloWorld{

     public static void main(String[] args){
        int[] LA = {1,2,4,5};
        int k = 2;
        int item = 3;
        int j = LA.length;
        int[] LA_NEW = new int[LA.length+1];


       while(j >k){
            LA_NEW[j] = LA[j-1];
            j = j-1;
        }
        LA_NEW[k] = item;
        for(int i = 0;i<k;i++){
            LA_NEW[i] = LA[i];
        }
        for(int i : LA_NEW){
            System.out.println(i);
        }
     }
}

You can prints lines with multiple colors without HTML as:

TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");        

word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");        

wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);

The above are good suggestions, but you can get at the text value of a cell in a grid view without wrapping it in a literal or label control. You just have to know what event to wire up. In this case, use the DataBound event instead, like so:

protected void GridView1_DataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[0].Text.Contains("sometext"))
        {
            e.Row.Cells[0].Font.Bold = true;
        }
    }
}

When running a debugger, you will see the text appear in this method.

Go to your pList and add or remove the following as per your requirement:

"Supported Interface Orientations" - Array
"Portrait (bottom home button)" - String
"Portrait (top home button)" - String
"Supported Interface Orientations (iPad)" - Array
"Portrait (bottom home button)" - String
"Portrait (top home button)" - String
"Landscape (left home button)" - String
"Landscape (right home button)" - String

Note: This method allows rotation for a entire app.

OR

Make a ParentViewController for UIViewControllers in a project (Inheritance Method).

//  UIappViewController.swift

import UIKit

class UIappViewController: UIViewController {
          super.viewDidLoad()   
    }
//Making methods to lock Device orientation.
    override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.Portrait
    }
    override func shouldAutorotate() -> Bool {
        return false
    }                                                                                                                                       
    override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }
    }

Associate every view controller's parent controller as UIappViewController.

//  LoginViewController.swift

import UIKit
import Foundation

class LoginViewController: UIappViewController{

    override func viewDidLoad()
    {
        super.viewDidLoad()

    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

This answer is not relevant for particular recepient, but maybe useful for others. I had similiar issue with 'selecting' right 'option' by value returned from database. I solved it by adding additional tag with applied display:none.

<?php
$status =  "NOT_ON_LIST";

$text = "<html>
<head>
</head>
<body>
<select id=\"statuses\">
   <option value=\"status\" selected=\"selected\" style=\"display:none\">$status</option>
   <option value=\"status\">OK</option>
   <option value=\"status\">DOWN</option>
   <option value=\"status\">UNKNOWN</option>
</select>
</body>
</html>";

print $text;
?>

have you tried ReText? It is a nice desktop Markdown editor

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

As long as you don't COMMIT or ROLLBACK a transaction, it's still "running" and potentially holding locks.

If your client (application or user) closes the connection to the database before committing, any still running transactions will be rolled back and terminated.

You can check if a element is disabled or not with this:

if($("#slcCausaRechazo").prop('disabled') == false)
{
//your code to realice 
}

Oops, immediately found 2//2.

building on mwigdahls answer. if you also need to do grouping here is how to get it to look like

group, csv
'group1', 'paul, john'
'group2', 'mary'

    --drop table #user
create table #user (groupName varchar(25), username varchar(25))

insert into #user (groupname, username) values ('apostles', 'Paul')
insert into #user (groupname, username) values ('apostles', 'John')
insert into #user (groupname, username) values ('family','Mary')


select
    g1.groupname
    , stuff((
        select ', ' + g.username
        from #user g        
        where g.groupName = g1.groupname        
        order by g.username
        for xml path('')
    ),1,2,'') as name_csv
from #user g1
group by g1.groupname

Just wrap your WebElement into Select Object as shown below

Select dropdown = new Select(driver.findElement(By.id("identifier")));

Once this is done you can select the required value in 3 ways. Consider an HTML file like this

<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do

Select dropdown = new Select(driver.findElement(By.id("designation")));

To select its option say 'Programmer' you can do

dropdown.selectByVisibleText("Programmer ");

or

dropdown.selectByIndex(1);

or

 dropdown.selectByValue("prog");

Use the RegExp constructor and multiple replacements to clarify the syntax:

function getCook(cookiename) 
  {
  // Get name followed by anything except a semicolon
  var cookiestring=RegExp(cookiename+"=[^;]+").exec(document.cookie);
  // Return everything after the equal sign, or an empty string if the cookie name not found
  return decodeURIComponent(!!cookiestring ? cookiestring.toString().replace(/^[^=]+./,"") : "");
  }

//Sample usage
var cookieValue = getCook('MYBIGCOOKIE');

I've thought long and hard about this and finally ended up with the solution I'll describe below. It's a pretty big step up in complexity but if you do make this step, you'll end up with what you are really after, which is deterministic results for future requests.

Your example of an item being deleted is only the tip of the iceberg. What if you are filtering by color=blue but someone changes item colors in between requests? Fetching all items in a paged manner reliably is impossible... unless... we implement revision history.

I've implemented it and it's actually less difficult than I expected. Here's what I did:

• I created a single table changelogs with an auto-increment ID column
• My entities have an id field, but this is not the primary key
• The entities have a changeId field which is both the primary key as well as a foreign key to changelogs.
• Whenever a user creates, updates or deletes a record, the system inserts a new record in changelogs, grabs the id and assigns it to a new version of the entity, which it then inserts in the DB
• My queries select the maximum changeId (grouped by id) and self-join that to get the most recent versions of all records.
• Filters are applied to the most recent records
• A state field keeps track of whether an item is deleted
• The max changeId is returned to the client and added as a query parameter in subsequent requests
• Because only new changes are created, every single changeId represents a unique snapshot of the underlying data at the moment the change was created.
• This means that you can cache the results of requests that have the parameter changeId in them forever. The results will never expire because they will never change.
• This also opens up exciting feature such as rollback / revert, synching client cache etc. Any features that benefit from change history.

The compiler may add padding for alignment requirements. Note that this applies not only to padding between the fields of a struct, but also may apply to the end of the struct (so that arrays of the structure type will have each element properly aligned).

For example:

struct foo_t {
    int x;
    char c;
};

Even though the c field doesn't need padding, the struct will generally have a sizeof(struct foo_t) == 8 (on a 32-bit system - rather a system with a 32-bit int type) because there will need to be 3 bytes of padding after the c field.

Note that the padding might not be required by the system (like x86 or Cortex M3) but compilers might still add it for performance reasons.

For Swift 5+, iOS 13+

extension UIViewController {
    static func topMostViewController() -> UIViewController? {
        if #available(iOS 13.0, *) {
            let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            return keyWindow?.rootViewController?.topMostViewController()
        }
        
        return UIApplication.shared.keyWindow?.rootViewController?.topMostViewController()
    }
    
    func topMostViewController() -> UIViewController? {
        if let navigationController = self as? UINavigationController {
            return navigationController.topViewController?.topMostViewController()
        }
        else if let tabBarController = self as? UITabBarController {
            if let selectedViewController = tabBarController.selectedViewController {
                return selectedViewController.topMostViewController()
            }
            return tabBarController.topMostViewController()
        }
            
        else if let presentedViewController = self.presentedViewController {
            return presentedViewController.topMostViewController()
        }
        
        else {
            return self
        }
    }
}

Usage:

When you are getting topMostViewController without instance of UIViewController

guard let viewController = UIViewController.topMostViewController() else { return }
print(viewController)

When you are getting topMostViewController of instance of UIViewController

let yourVC = UIViewController()
guard let vc = yourVC.topMostViewController() else { return }
print(vc)

As per official Cordova documentation it supports only JDK 1.8 not greater till the date (April 2018). Or there might be problem with version detection script within cordova.

In addition to the accepted answer, I would like to add one info, that NuGet packages in Visual Studio 2017 are located in the project file itself. I.e., right click on the project -> edit, to find all package reference entries.

One core (doesn't invoke external process):

while true; do true; done

Two cores:

while true; do /bin/true; done

The latter only makes both of mine go to ~50% though...

This one will make both go to 100%:

while true; do echo; done

In A1 of your new sheet, put this:

=OFFSET(Sheet1!$A$1,(ROW()-1)*7,0)

... and copy down. If you start somewhere other than row 1, change ROW() to ROW(A1) or some other cell on row 1, then copy down again.

If you want to copy the nth line but multiple columns, use the formula:

=OFFSET(Sheet1!A$1,(ROW()-1)*7,0)

This can be copied right too.

sed -i.bak "s#https.*\.com#$pub_url#g" MyHTMLFile.html

If you have a link to be added, try this. Search for the URL as above (starting with https and ending with.com here) and replace it with a URL string. I have used a variable $pub_url here. s here means search and g means global replacement.

It works !

I'd recommend using a class instead of setting css properties. So instead of this:

$(this).css({"border-color": "#C1E0FF", 
             "border-width":"1px", 
             "border-style":"solid"});

Define a css class:

.border 
{ 
  border-color: #C1E0FF; 
  border-width:1px; 
  border-style:solid; 
}

And then change your javascript to:

$(this).addClass("border");

You don't need an onclick. Assuming you're using Bootstrap 3 Bootstrap 3 Documentation

<div class="span4 proj-div" data-toggle="modal" data-target="#GSCCModal">Clickable content, graphics, whatever</div>

I realize this question is a bit dated and since it shows up on Google search for similar issue I thought I will expand a little bit more on top of @CowWarrior's answer. I was looking for somewhat similar solution, and after scouring through countless SO question/answers and Bootstrap documentations the solution was pretty simple. Again, this would be using inbuilt Bootstrap collapse class to show/hide divs and Bootstrap's "Collapse Event".

What I realized is that it is easy to do it using a Bootstrap Accordion, but most of the time even though the functionality required is "somewhat" similar to an Accordion, it's different in a way that one would want to show hide <div> based on, lets say, menu buttons on a navbar. Below is a simple solution to this. The anchor tags (<a>) could be navbar items and based on a collapse event the corresponding div will replace the existing div. It looks slightly sloppy in CodeSnippet, but it is pretty close to achieving the functionality-

All that the JavaScript does is makes all the other <div> hide using

$(".main-container.collapse").not($(this)).collapse('hide');

when the loaded <div> is displayed by checking the Collapse event shown.bs.collapse. Here's the Bootstrap documentation on Collapse Event.

Note: main-container is just a custom class.

Here it goes-

$(".main-container.collapse").on('shown.bs.collapse', function () {    _x000D_
//when a collapsed div is shown hide all other collapsible divs that are visible_x000D_
       $(".main-container.collapse").not($(this)).collapse('hide');_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>_x000D_

<a href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</a>_x000D_
_x000D_
<div id="Bar" class="main-container collapse in">_x000D_
    This div (#Bar) is shown by default and can toggle_x000D_
</div>_x000D_
<div id="Foo" class="main-container collapse">_x000D_
    This div (#Foo) is hidden by default_x000D_
</div>

iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.

There is good uses of public nested members too...

Nested classes have access to the private members of the outer class. So a scenario where this is the right way would be when creating a Comparer (ie. implementing the IComparer interface).

In this example, the FirstNameComparer has access to the private _firstName member, which it wouldn't if the class was a separate class...

public class Person
{
    private string _firstName;
    private string _lastName;
    private DateTime _birthday;

    //...
    
    public class FirstNameComparer : IComparer<Person>
    {
        public int Compare(Person x, Person y)
        {
            return x._firstName.CompareTo(y._firstName);
        }
    }
}

In your database what is the type of "IDNO"? You may need to escape the sql here:

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);

If you just need to go from BitmapImage to Bitmap it's quite easy,

private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
    {
        return new Bitmap(bitmapImage.StreamSource);
    }

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

Flask-Sqlalchemy

Delete All Records

#for all records
db.session.query(Model).delete()
db.session.commit()

Deleted Single Row

here DB is the object Flask-SQLAlchemy class. It will delete all records from it and if you want to delete specific records then try filter clause in the query. ex.

#for specific value
db.session.query(Model).filter(Model.id==123).delete()
db.session.commit()

Delete Single Record by Object

record_obj = db.session.query(Model).filter(Model.id==123).first()
db.session.delete(record_obj)
db.session.commit()

I created an insecure but simple text cipher/decipher util. No dependencies with any external library.

These are the functions

const cipher = salt => {
    const textToChars = text => text.split('').map(c => c.charCodeAt(0));
    const byteHex = n => ("0" + Number(n).toString(16)).substr(-2);
    const applySaltToChar = code => textToChars(salt).reduce((a,b) => a ^ b, code);

    return text => text.split('')
        .map(textToChars)
        .map(applySaltToChar)
        .map(byteHex)
        .join('');
}

const decipher = salt => {
    const textToChars = text => text.split('').map(c => c.charCodeAt(0));
    const applySaltToChar = code => textToChars(salt).reduce((a,b) => a ^ b, code);
    return encoded => encoded.match(/.{1,2}/g)
        .map(hex => parseInt(hex, 16))
        .map(applySaltToChar)
        .map(charCode => String.fromCharCode(charCode))
        .join('');
}

And you can use them as follows:

// To create a cipher
const myCipher = cipher('mySecretSalt')

//Then cipher any text:
myCipher('the secret string')   // --> "7c606d287b6d6b7a6d7c287b7c7a61666f"

//To decipher, you need to create a decipher and use it:
const myDecipher = decipher('mySecretSalt')
myDecipher("7c606d287b6d6b7a6d7c287b7c7a61666f")    // --> 'the secret string'

The only solution I've found is to first create the project in Android Studio, then close the project, then import the project. I searched all over and could not find the root cause and all other solutions people posted didn't work.

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

If you are using Jackson to deserialize the response body, one very simple solution is to use request.getResponseBodyAsStream() instead of request.getResponseBodyAsString()

Here is my updated code. Checks to see if version exists before saving and saves as the next available version number.

Sub SaveNewVersion()
    Dim fileName As String, index As Long, ext As String
    arr = Split(ActiveWorkbook.Name, ".")
    ext = arr(UBound(arr))

    fileName = ActiveWorkbook.FullName

    If InStr(ActiveWorkbook.Name, "_v") = 0 Then
        fileName = ActiveWorkbook.Path & "\" & Left(ActiveWorkbook.Name, InStr(ActiveWorkbook.Name, ".") - 1) & "_v1." & ext
    End If

   Do Until Len(Dir(fileName)) = 0

        index = CInt(Split(Right(fileName, Len(fileName) - InStr(fileName, "_v") - 1), ".")(0))
        index = index + 1
        fileName = Left(fileName, InStr(fileName, "_v") - 1) & "_v" & index & "." & ext

    ActiveWorkbook.SaveAs (fileName)

In C++, nested classes are not connected to any instance of the outer class. If you want bar to access non-static members of foo, then bar needs to have access to an instance of foo. Maybe something like:

class bar {
  public:
    int getA(foo & f ) {return foo.a;}
};

Or maybe

class bar {
  private:
    foo & f;

  public:
    bar(foo & g)
    : f(g)
    {
    }

    int getA() { return f.a; }
};

In any case, you need to explicitly make sure you have access to an instance of foo.

Actually you can find very easy the day a video was created, right-click, property but remember it will only give the details of any copy date of the video but if you do click where it says DETAILS JUST there is the information you need, the original date that the archive was created on. Note that most modern devices will produce this information when you take pictures and videos but others will not.

I have this issue too. I am running 1.6 but want to build the code I'm working on with 1.5. I've changed the JAVA_HOME and PATH (both user and system) to no avail.

The answer is that the installer for 1.6 dropped java.exe, javaw.exe, and javaws.exe into my Windows\System32 folder (Windows 7).

I solved it by renaming those files to java_wrong.exe, javaw_wrong.exe, and javaws_wrong.exe. Only after doing that does it pick up the correct version of java as defined in JAVA_HOME and PATH. I renamed the files thusly because that deleted them in an easily reversible manner.

Hope this helps!

Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.

ASPX

<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
    <ItemTemplate>
        <div id="width:50%;height:30px;background:#0f0a0f;">
            <asp:Label ID="lblSr" runat="server" 
               style="width:30%;float:left;text-align:right;text-indent:-2px;" />
            <span 
               style="width:65%;float:right;text-align:left;text-indent:-2px;" >
            <%# Eval("Item") %>
            </span>
        </div>
    </ItemTemplate>
</asp:Repeater>

Code Behind:

    protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
    {
        Label l = e.Item.FindControl("lblSr") as Label;
        if (l != null)
            l.Text = e.Item.ItemIndex + 1+"";
    }

you can also connect to database as "normal" user (not postgres):

postgres=# \connect opensim Opensim_Tester localhost;

Password for user Opensim_Tester:    

You are now connected to database "opensim" as user "Opensim_Tester" on host "localhost" at port "5432"

This can be done using the numeric_limits in C++:

http://www.cplusplus.com/reference/limits/numeric_limits/

These are the methods you probably want to look at:

infinity()  T   Representation of positive infinity, if available.
quiet_NaN() T   Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T   Representation of signaling "Not-a-Number", if available.

From a ReactJS test, the following code successfully writes a file:

import writeJsonFile from 'write-json-file';

const ans = 42;
writeJsonFile('answer.txt', ans);

const json = {"answer": ans};
writeJsonFile('answer_json.txt', json);

The file is written to the directory containing the tests, so writing to an actual JSON file '*.json' creates a loop!

It shouldn't matter, any more than if you encoded the letter A as %41.

However, if you're dealing with a system that doesn't recognize one form, it seems like you're just going to have to give it what it expects regardless of what the "spec" says.

Microsoft just announced .NET Core v 3.0, which is a much-improved version of .NET Core.

The loop in your code is only an over-simplified example, right?

It would be better to create the PreparedStatement only once, and re-use it over and over again in the loop.

In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.

To address the situation that you want to re-use the Java-side PreparedStatement, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement for the same SQL on the same connection, it will give you the same (cached) instance.

About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.

We can use the angular.element(document).ready() method to attach callbacks for when the document is ready. We can simply attach the callback in the controller like so:

angular.module('MyApp', [])

.controller('MyCtrl', [function() {
    angular.element(document).ready(function () {
        document.getElementById('msg').innerHTML = 'Hello';
    });
}]);

It looks as if you were on the right track. You just need to add the else statement after the ";" following the "then" statement. Also I would split the first line from the second line with a semicolon instead of joining it with "&&".

maxline='cat journald.conf | grep "#SystemMaxUse="'; if [ $maxline == "#SystemMaxUse=" ]; then sed 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf > journald.conf2 && mv journald.conf2 journald.conf; else echo "This file has been edited. You'll need to do it manually."; fi

Also in your original script, when declaring maxline you used back-ticks "`" instead of single quotes "'" which might cause problems.

Hide columns dynamically

The previous answers are using legacy DataTables syntax. In v 1.10+, you can use column().visible():

var dt = $('#example').DataTable();
//hide the first column
dt.column(0).visible(false);

To hide multiple columns, columns().visible() can be used:

var dt = $('#example').DataTable();
//hide the second and third columns
dt.columns([1,2]).visible(false);

Here is a Fiddle Demo.

Hide columns when the table is initialized

To hide columns when the table is initialized, you can use the columns option:

$('#example').DataTable( {
    'columns' : [
        null,
        //hide the second column
        {'visible' : false },
        null,
        //hide the fourth column
        {'visible' : false }
    ]
});

For the above method, you need to specify null for columns that should remain visible and have no other column options specified. Or, you can use columnDefs to target a specific column:

$('#example').DataTable( {
    'columnDefs' : [
        //hide the second & fourth column
        { 'visible': false, 'targets': [1,3] }
    ]
});

With formulas, what you can do is:

• in a new column (say col D - cell D2), add =COUNTA(A2:C2)
• drag this formula till the end of your data (say cell D4 in our example)
• add a last formula to sum it up (e.g in cell D5): =SUM(D2:D4)

I was doing some extensive mathematics with FORTRAN and C for a couple of years. From my own experience I can tell that FORTRAN is sometimes really better than C but not for its speed (one can make C perform as fast as FORTRAN by using appropriate coding style) but rather because of very well optimized libraries like LAPACK, and because of great parallelization. On my opinion, FORTRAN is really awkward to work with, and its advantages are not good enough to cancel that drawback, so now I am using C+GSL to do calculations.

Two options save vijay.sql

declare
begin
execute immediate

SELECT wk.*,bbc.distance_km ,NVL(bbc.tactical_broadband_offer,0) tactical_broadband_offer ,
       sel.tactical_select_executive_flag,

AND    wk.mpn = sel.mpn (+)
AND    wk.mpn = res.mpn (+)

end;

The above will generate table names automatically based on sysdate. If you still need to pass as variable, then save vijay.sql as

I have similar situation like you. I dont wannt sublime open editor for binary like jpg png files. Instead open system default application is more reasonable.

1. create one Build. Just like the accepted answer. But it will both open default application and hex editor.
2. Pulgin OpenDefaultApplication https://github.com/SublimeText/OpenDefaultApplication It will have context right click menu OpenInDefaultApplication. But It will both open default application and hex editor as well

3. Pulgin: Non Text Files https://packagecontrol.io/packages/Non%20Text%20Files Add config in the user settting

   "binary_file_patterns": ["*.JPG","*.jpg", "*.jpeg", "*.png", "*.gif", "*.ttf", "*.tga", "*.dds", "*.ico", "*.eot", "*.pdf", "*.swf", "*.jar", "*.zip"],
   "prevent_bin_preview": true,
   "open_externally_patterns": [
      "*.JPG",
      "*.jpg",
      "*.jpeg",
      "*.JPEG",
      "*.png",
       "*.PGN",
      "*.gif",
       "*.GIF",
       "*.zip",
       "*.ZIP",
       "*.pdf",
       "*.PDF"
   ]
   

I choose the third way, it's quite sutiable for me. It will open jpg file in system default application and quickly close the edit mode automaically at the same time. As to the first two ways, you can set "preview_on_click": false, to stop openning automaticlly the hex editor compromisely.

I didn't see pyformat in the list so I thought I'd throw it in:

                ))
console.log(pyformat('The {0} {1} jumped over the {1}'
                , ['brown' ,'fox' ,'foobar']
                ))
console.log(pyformat('The {color} {animal} jumped over the {thing}'
                , [] ,{color: 'brown' ,animal: 'fox' ,thing: 'foobaz'}
                ))

[1,3].inject([1,1,1,2,2,3]) do |memo,element|
  memo.tap do |memo|
    i = memo.find_index(e)
    memo.delete_at(i) if i
  end
end

Using only vanilla sed and awk, and without using $RANDOM, a simple, space-efficient and reasonably fast "one-liner" for selecting a single line pseudo-randomly from a file named FILENAME is as follows:

sed -n $(awk 'END {srand(); r=rand()*NR; if (r<NR) {sub(/\..*/,"",r); r++;}; print r}' FILENAME)p FILENAME

(This works even if FILENAME is empty, in which case no line is emitted.)

One possible advantage of this approach is that it only calls rand() once.

As pointed out by @AdamKatz in the comments, another possibility would be to call rand() for each line:

awk 'rand() * NR < 1 { line = $0 } END { print line }' FILENAME

(A simple proof of correctness can be given based on induction.)

Caveat about rand()

"In most awk implementations, including gawk, rand() starts generating numbers from the same starting number, or seed, each time you run awk."

According to the certification exam you should use Convert.ToXXX() whenever possible for simple conversions because it optimizes performance better than CXXX conversions.

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?

I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwd which has issues with OverlayFS. I found information about this here:

It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes (if you're actually building bash and your C library does malloc a getcwd call).

The good thing is, this one is really easily and deterministically to analyze: Either, the msi package is really not installed on the system or you're doing something wrong. Of course the correct call is:

msiexec /x {A4BFF20C-A21E-4720-88E5-79D5A5AEB2E8}

(Admin rights needed of course- With curly braces without any quotes here- quotes are only needed, if paths or values with blank are specified in the commandline.)
If the message is: "This action is only valid for products that are currently installed", then this is true. Either the package with this ProductCode is not installed or there is a typo.

To verify where the fault is:

1. First try to right click on the (probably) installed .msi file itself. You will see (besides "Install" and "Repair") an Uninstall entry. Click on that.
   a) If that uninstall works, your msi has another ProductCode than you expect (maybe you have the wrong WiX source or your build has dynamic logging where the ProductCode changes).
   b) If that uninstall gives the same "...only valid for products already installed" the package is not installed (which is obviously a precondition to be able to uninstall it).

2. If 1.a) was the case, you can look for the correct ProductCode of your package, if you open your msi file with Orca, Insted or another editor/tool. Just google for them. Look there in the table with the name "Property" and search for the string "ProductCode" in the first column. In the second column there is the correct value.

There are no other possibilities.

Just a suggestion for the used commandline: I would add at least the "/qb" for a simple progress bar or "/qn" parameter (the latter for complete silent uninstall, but makes only sense if you are sure it works).

The negative margin trick:

http://pastehtml.com/view/1dujbt3.html

Not elegant, I suppose, but it works in some cases.

Try this..

#container
{
   height: auto;
   min-height:100%;
   width: 100%;
}

#container #mainContentsWrapper
{
   float: left;

   height: auto;
   min-height:100%
   width: 70%;
   margin: 0;
   padding: 0;
}


#container #sidebarWrapper
{      
   float: right;

   height: auto;
   min-height:100%
   width: 29.7%;
   margin: 0;
   padding: 0;
}

Did have the same problem. Spent like 6 hours when had to migrate some servers. Tried all suggestions available on this topic and others.

Solution was as simple as server restart!

Git 1.8.2 features a new option, --remote, that will enable exactly this behavior. Running

git submodule update --remote --merge

will fetch the latest changes from upstream in each submodule, merge them in, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

The existing answers are better for how to get the correct value, but I can at least explain why getrusage isn't working for you.

man 2 getrusage:

The above struct [rusage] was taken from BSD 4.3 Reno. Not all fields are meaningful under Linux. Right now (Linux 2.4, 2.6) only the fields ru_utime, ru_stime, ru_minflt, ru_majflt, and ru_nswap are maintained.

min(df['some_property'])
max(df['some_property'])

The built-in functions work well with Pandas Dataframes.

1) Create KeyboardHeightHelper:

public class KeyboardHeightHelper {

    private final View decorView;
    private int lastKeyboardHeight = -1;

    public KeyboardHeightHelper(Activity activity, View activityRootView, OnKeyboardHeightChangeListener listener) {
        this.decorView = activity.getWindow().getDecorView();
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
            int keyboardHeight = getKeyboardHeight();
            if (lastKeyboardHeight != keyboardHeight) {
                lastKeyboardHeight = keyboardHeight;
                listener.onKeyboardHeightChange(keyboardHeight);
            }
        });
    }

    private int getKeyboardHeight() {
        Rect rect = new Rect();
        decorView.getWindowVisibleDisplayFrame(rect);
        return decorView.getHeight() - rect.bottom;
    }

    public interface OnKeyboardHeightChangeListener {
        void onKeyboardHeightChange(int keyboardHeight);
    }
}

2) Let your activity be full screen:

activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

3) Listen for keyboard height changes and add bottom padding for your view:

View rootView = activity.findViewById(R.id.root); // your root view or any other you want to resize
KeyboardHeightHelper effectiveHeightHelper = new KeyboardHeightHelper(
        activity, 
        rootView,
        keyboardHeight -> rootView.setPadding(0, 0, 0, keyboardHeight));

So, each time keyboard will appear on the screen - bottom padding for your view will change, and content will be rearranged.

NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples.

// Both parameters are optional, use empty string for default value
func Concat1(a string, b int) string {
  if a == "" {
    a = "default-a"
  }
  if b == 0 {
    b = 5
  }

  return fmt.Sprintf("%s%d", a, b)
}

// a is required, b is optional.
// Only the first value in b_optional will be used.
func Concat2(a string, b_optional ...int) string {
  b := 5
  if len(b_optional) > 0 {
    b = b_optional[0]
  }

  return fmt.Sprintf("%s%d", a, b)
}

// A declarative default value syntax
// Empty values will be replaced with defaults
type Parameters struct {
  A string `default:"default-a"` // this only works with strings
  B string // default is 5
}

func Concat3(prm Parameters) string {
  typ := reflect.TypeOf(prm)

  if prm.A == "" {
    f, _ := typ.FieldByName("A")
    prm.A = f.Tag.Get("default")
  }

  if prm.B == 0 {
    prm.B = 5
  }

  return fmt.Sprintf("%s%d", prm.A, prm.B)
}

func Concat4(args ...interface{}) string {
  a := "default-a"
  b := 5

  for _, arg := range args {
    switch t := arg.(type) {
      case string:
        a = t
      case int:
        b = t
      default:
        panic("Unknown argument")
    }
  }

  return fmt.Sprintf("%s%d", a, b)
}

The preferred way is to always use the literal syntax with square brackets; its behaviour is predictable for any number of items, unlike Array's. What's more, Array is not a keyword, and although it is not a realistic situation, someone could easily overwrite it:

function Array() { return []; }

alert(Array(1, 2, 3)); // An empty alert box

However, the larger issue is that of consistency. Someone refactoring code could come across this function:

function fetchValue(n) {
    var arr = new Array(1, 2, 3);

    return arr[n];
}

As it turns out, only fetchValue(0) is ever needed, so the programmer drops the other elements and breaks the code, because it now returns undefined:

var arr = new Array(1);

for me it worked by adding

1) "You can run the mongodb instance without username and password first.---OK

2) "Then you can add the user to the system database of the mongodb which is default one using the query below".---OK

db.createUser({
  user: "myUserAdmin",
  pwd: "abc123",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ],
  mechanisms:[ "SCRAM-SHA-1" ] // I added this line

})

IIRC ...

setSize sets the size of the component.

setPreferredSize sets the preferred size. The Layoutmanager will try to arrange that much space for your component.

It depends on whether you're using a layout manager or not ...

Remember, you are NOT allowed to do this.

class foo():
    def print_hello(self):
        print("Hello")       # This next line will produce an ERROR!
    self.print_hello()       # <---- it calls a class function, inside a class,
                             # but outside a class function. Not allowed.

You must call a class function from either outside the class, or from within a function in that class.

Python 3:

user225312's answer is correct:

A. To count number of characters in str object, you can use len() function:

>>> print(len('please anwser my question'))
25

B. To get memory size in bytes allocated to store str object, you can use sys.getsizeof() function

>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50

Python 2:

It gets complicated for Python 2.

A. The len() function in Python 2 returns count of bytes allocated to store encoded characters in a str object.

Sometimes it will be equal to character count:

>>> print(len('abc'))
3

But sometimes, it won't:

>>> print(len('???'))  # String contains Cyrillic symbols
6

That's because str can use variable-length encoding internally. So, to count characters in str you should know which encoding your str object is using. Then you can convert it to unicode object and get character count:

>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols 
3

B. The sys.getsizeof() function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object

>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32

Lots of answer provide specific techniques, rule of thumbs etc to understand this particular instance of variable declaration. But there is a generic technique of understand any declaration:

Clockwise/Spiral Rule

A)

const char *a;

As per the clockwise/spiral rule a is pointer to character that is constant. Which means character is constant but the pointer can change. i.e. a = "other string"; is fine but a[2] = 'c'; will fail to compile

B)

char * const a;

As per the rule, a is const pointer to a character. i.e. You can do a[2] = 'c'; but you cannot do a = "other string";

You need to add tabs plugin to your code

<script type="text/javascript" src="assets/twitterbootstrap/js/bootstrap-tab.js"></script>

Well, it didn't work. I made some tests and it started working when:

1. moved (updated to 1.7) jQuery script to <head> section
2. added data-toggle="tab" to links and id for <ul> tab element
3. changed $(".tabs").tabs(); to $("#tabs").tab();
4. and some other things that shouldn't matter

When using the saveas function the resolution isn't as good as when manually saving the figure with File-->Save As..., It's more recommended to use hgexport instead, as follows:

hgexport(gcf, 'figure1.jpg', hgexport('factorystyle'), 'Format', 'jpeg');

This will do exactly as manually saving the figure.

If your question is about IIS(or other server) configuration - yes, it's possible. All you need is to create ports mapping under your Default Site or Virtual Directory and assign specific ports to the site you need. For example it is sometimes very useful for web services, when default port is assigned to some UI front-end and you want to assign service to the same address but with different port.

A lazy way of doing this if there are alot of tables to be deleted.

1. Get table using the below

   • For sql server - SELECT CONCAT(name,',') Table_Name FROM SYS.tables;
   • For oralce - SELECT CONCAT(TABLE_NAME,',') FROM SYS.ALL_TABLES;

2. Copy and paste the table names from the result set and paste it after the DROP command.

If you are not already using lodash I wouldn't recommend installing it just for this one method. I suggest instead a more narrowly specialized library such as 'clone':

npm install clone

a simple windows search for android-sdk should help you find it, assuming you named it that. You also might just wanna try sdk

@momo's answer for Apache HttpClient, version 4.3.1 or later. I'm using JSON-Java to build my JSON object:

JSONObject json = new JSONObject();
json.put("someKey", "someValue");    

CloseableHttpClient httpClient = HttpClientBuilder.create().build();

try {
    HttpPost request = new HttpPost("http://yoururl");
    StringEntity params = new StringEntity(json.toString());
    request.addHeader("content-type", "application/json");
    request.setEntity(params);
    httpClient.execute(request);
// handle response here...
} catch (Exception ex) {
    // handle exception here
} finally {
    httpClient.close();
}

I use this and it works fine

Most of the time we login to remote server using ssh. If you start a shell script and you logout then the process is killed. Nohup helps to continue running the script in background even after you log out from shell.

Nohup command name &
eg: nohup sh script.sh &

Nohup catches the HUP signals. Nohup doesn't put the job automatically in the background. We need to tell that explicitly using &

The following works for me in Firefox and Internet Explorer:

     <embed src="./test.wmv" autostart="true" showcontrols="true" showstatusbar="1" bgcolor="white" width="320" height="310">
</object>

This method name should do the trick:

Page<QueuedBook> findByBookIdRegion(Region region, Pageable pageable);

More info on that in the section about query derivation of the reference docs.

It sounds like you might need to create and query linked database servers in SQL Server

At the moment you've created a query that's going between different databases using a 3 part name mydatabase.dbo.mytable but you need to go up a level and use a 4 part name myserver.mydatabase.dbo.mytable, see this post on four part naming for more info

edit
The four part naming for your existing query would be as shown below (which I suspect you may have already tried?), but this assumes you can "get to" the remote database with the four part name, you might need to edit your host file / register the server or otherwise identify where to find database.windows.net.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks])
SELECT [InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks] FROM [BC1-PC].[testdabse].[dbo].[invoice]

If you can't access the remote server then see if you can create a linked database server:

EXEC sp_addlinkedserver [database.windows.net];
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [database.windows.net].basecampdev.dbo.invoice;
GO

Then you can just query against MyEmployee without needing the full four part name

You could try the fnmatch module, it's got a shell-like wildcard syntax

or can use regular expressions

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

As said by Sparky in comments on many answers to this question, there is NOT any textarea value for the type attribute of the input tag.

On other terms, the following markup is not valid :

<input type="textarea" />

And the browser replaces it by the default :

<input type="text" />

To define a multi-lines text input, use :

<textarea></textarea>

See the textarea element documentation for more details.

you have to call a function before it can return anything.

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction();
}

var test = mainFunction();
alert(test);

Or:

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction;
}

var test = mainFunction();
alert( test() );

for your actual code. The return should be outside, in the main function. The callback is called somewhere inside the getLocations method and hence its return value is not recieved inside your main function.

function reverseGeocode(latitude,longitude){
    var address = "";
    var country = "";
    var countrycode = "";
    var locality = "";

    var geocoder = new GClientGeocoder();
    var latlng = new GLatLng(latitude, longitude);

    geocoder.getLocations(latlng, function(addresses) {
     address = addresses.Placemark[0].address;
     country = addresses.Placemark[0].AddressDetails.Country.CountryName;
     countrycode = addresses.Placemark[0].AddressDetails.Country.CountryNameCode;
     locality = addresses.Placemark[0].AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName;
    });   
    return country
   }

If the request calls are buried somewhere deep in the code and you do not want to install the server certificate, then, just for debug purposes only, it's possible to monkeypatch requests:

import requests.api
import warnings


def requestspatch(method, url, **kwargs):
    kwargs['verify'] = False
    return _origcall(method, url, **kwargs)

_origcall = requests.api.request
requests.api.request = requestspatch
warnings.warn('Patched requests: SSL verification disabled!')

Never use in production!

you can also use:

pip install package==0.5.*

which is more consistent and easy to read.

I usually use the .ToString() method on exceptions to present the full exception information (including the inner stack trace) in text:

catch (MyCustomException ex)
{
    Debug.WriteLine(ex.ToString());
}

Sample output:

ConsoleApplication1.MyCustomException: some message .... ---> System.Exception: Oh noes!
   at ConsoleApplication1.SomeObject.OtherMethod() in C:\ConsoleApplication1\SomeObject.cs:line 24
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 14
   --- End of inner exception stack trace ---
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 18
   at ConsoleApplication1.Program.DoSomething() in C:\ConsoleApplication1\Program.cs:line 23
   at ConsoleApplication1.Program.Main(String[] args) in C:\ConsoleApplication1\Program.cs:line 13

A slight more difficult answer that uses ControlTemplate and has an animation effect (adapted from https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/customizing-the-appearance-of-an-existing-control)

In your resource dictionary define a control template for your button like this one:

<ControlTemplate TargetType="Button" x:Key="testButtonTemplate2">
    <Border Name="RootElement">
        <Border.Background>
            <SolidColorBrush x:Name="BorderBrush" Color="Black"/>
        </Border.Background>

        <Grid Margin="4" >
            <Grid.Background>
                <SolidColorBrush x:Name="ButtonBackground" Color="Aquamarine"/>
            </Grid.Background>
            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="4,5,4,4"/>
        </Grid>
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal"/>
                <VisualState x:Name="MouseOver">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Pressed">
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Color" To="Red"/>
                    </Storyboard>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>
    </Border>
</ControlTemplate>

in your XAML you can use the template above for your button as below:

Define your button

<Button Template="{StaticResource testButtonTemplate2}" 
HorizontalAlignment="Center" VerticalAlignment="Center" 
Foreground="White">My button</Button>

Hope it helps

To upload files to your repo without using the command-line, simply type this after your repository name in the browser:

https://github.com/yourname/yourrepositoryname/upload/master

and then drag and drop your files.(provided you are on github and the repository has been created beforehand)

Presuming every new branch in your tree is a div, I have implemented this solution with 2 functions:

function fillArray(vector1,vector2){
    for (var i = 0; i < vector1.length; i++){
        if (vector1[i].id.indexOf('q17_') == 0)
            vector2.push(vector1[i]);
        if(vector1[i].tagName == 'DIV')
            fillArray (document.getElementById(vector1[i].id).children,vector2);
    }
}

function selectAllElementsInsideDiv(divId){ 
    var matches = new Array();
    var searchEles = document.getElementById(divId).children;
    fillArray(searchEles,matches);
    return matches;
}

Now presuming your div's id is 'myDiv', all you have to do is create an array element and set its value to the function's return:

var ElementsInsideMyDiv = new Array();
ElementsInsideMyDiv =  selectAllElementsInsideDiv('myDiv')

I have tested it and it worked for me. I hope it helps you.

O...M...G I was getting this error too and I spent almost 2 days on it and now I finally managed to solve it. Honestly...the error had nothing to do with what the problem was. In my case it was a simple matter of syntax. I was trying to run a python module standalone that used some django models in a django context, but the module itself wasn't a django model. But I was declaring the class wrong

instead of having

class Scrapper:
    name = ""
    main_link= ""
    ...

I was doing

class Scrapper(Website):
    name = ""
    main_link= ""
    ...

which is obviously wrong. The message is so misleading that I couldn't help myself but think it was some issue with configuration or just using django in a wrong way since I'm very new to it.

I'll share this here for someone newbie as me going through the same silliness can hopefully solve their issue.

There are two ways to do this. First is like this:

while True:             # Loop continuously
    inp = raw_input()   # Get the input
    if inp == "":       # If it is a blank line...
        break           # ...break the loop

The second is like this:

inp = raw_input()       # Get the input
while inp != "":        # Loop until it is a blank line
    inp = raw_input()   # Get the input again

Note that if you are on Python 3.x, you will need to replace raw_input with input.

You can use the following "trick" to parse any valid URL. It takes advantage of the anchor element's special href-related property, hash.

With jQuery

function getHashFromUrl(url){
    return $("<a />").attr("href", url)[0].hash.replace(/^#/, "");
}
getHashFromUrl("www.example.com/task1/1.3.html#a_1"); // a_1

With plain JS

function getHashFromUrl(url){
    var a = document.createElement("a");
    a.href = url;
    return a.hash.replace(/^#/, "");
};
getHashFromUrl("www.example.com/task1/1.3.html#a_1"); // a_1

I believe you can use the append method

bigdata = data1.append(data2, ignore_index=True)

to keep their indexes just dont use the ignore_index keyword ...

Given this binary tree:

Breadth First Traversal:
Traverse across each level from left to right.

"I'm G, my kids are D and I, my grandkids are B, E, H and K, their grandkids are A, C, F"

- Level 1: G 
- Level 2: D, I 
- Level 3: B, E, H, K 
- Level 4: A, C, F

Order Searched: G, D, I, B, E, H, K, A, C, F

Depth First Traversal:
Traversal is not done ACROSS entire levels at a time. Instead, traversal dives into the DEPTH (from root to leaf) of the tree first. However, it's a bit more complex than simply up and down.

There are three methods:

1) PREORDER: ROOT, LEFT, RIGHT.
You need to think of this as a recursive process:  
Grab the Root. (G)  
Then Check the Left. (It's a tree)  
Grab the Root of the Left. (D)  
Then Check the Left of D. (It's a tree)  
Grab the Root of the Left (B)  
Then Check the Left of B. (A)  
Check the Right of B. (C, and it's a leaf node. Finish B tree. Continue D tree)  
Check the Right of D. (It's a tree)  
Grab the Root. (E)  
Check the Left of E. (Nothing)  
Check the Right of E. (F, Finish D Tree. Move back to G Tree)  
Check the Right of G. (It's a tree)  
Grab the Root of I Tree. (I)  
Check the Left. (H, it's a leaf.)  
Check the Right. (K, it's a leaf. Finish G tree)  
DONE: G, D, B, A, C, E, F, I, H, K  

2) INORDER: LEFT, ROOT, RIGHT
Where the root is "in" or between the left and right child node.  
Check the Left of the G Tree. (It's a D Tree)  
Check the Left of the D Tree. (It's a B Tree)  
Check the Left of the B Tree. (A)  
Check the Root of the B Tree (B)  
Check the Right of the B Tree (C, finished B Tree!)  
Check the Right of the D Tree (It's a E Tree)  
Check the Left of the E Tree. (Nothing)  
Check the Right of the E Tree. (F, it's a leaf. Finish E Tree. Finish D Tree)...  
Onwards until...   
DONE: A, B, C, D, E, F, G, H, I, K  

3) POSTORDER: 
LEFT, RIGHT, ROOT  
DONE: A, C, B, F, E, D, H, K, I, G

Usage (aka, why do we care):
I really enjoyed this simple Quora explanation of the Depth First Traversal methods and how they are commonly used:
"In-Order Traversal will print values [in order for the BST (binary search tree)]"
"Pre-order traversal is used to create a copy of the [binary search tree]."
"Postorder traversal is used to delete the [binary search tree]."

I really liked Al P's answer but wanted uniqueness enforced cheaply so I took it one step further - use a directory. There are some obvious limitations (directory file limits, invalid file names) but it should work for most cases.

hinit() {
    rm -rf /tmp/hashmap.$1
    mkdir -p /tmp/hashmap.$1
}

hput() {
    printf "$3" > /tmp/hashmap.$1/$2
}

hget() {
    cat /tmp/hashmap.$1/$2
}

hkeys() {
    ls -1 /tmp/hashmap.$1
}

hdestroy() {
    rm -rf /tmp/hashmap.$1
}

hinit ids

for (( i = 0; i < 10000; i++ )); do
    hput ids "key$i" "value$i"
done

for (( i = 0; i < 10000; i++ )); do
    printf '%s\n' $(hget ids "key$i") > /dev/null
done

hdestroy ids

It also performs a tad bit better in my tests.

$ time bash hash.sh 
real    0m46.500s
user    0m16.767s
sys     0m51.473s

$ time bash dirhash.sh 
real    0m35.875s
user    0m8.002s
sys     0m24.666s

Just thought I'd pitch in. Cheers!

Edit: Adding hdestroy()

For those users of wamp server, follow the first 2 steps of @Raul Chipad's solution then:

3. Click the wamp icon (normally in green), go to "Apache" > "Apache modules" > "rewrite_module". The "rewrite_module" should be ticked! And then it's the way to go!

My understanding is if you set controls.Visible = false during initial page load, it doesn't get rendered in the client response. My suggestion to solve your problem is

Don't use placeholder, judging from the scenario, you don't really need a placeholder, unless you need to dynamically add controls on the server side. Use div, without runat=server. You can always controls the visiblity of that div using css. If you need to add controls dynamically later, use placeholder, but don't set visible = false. Placeholder won't have any display anyway, Set the visibility of that placeholder using css. Here's how to do it programmactically :

placeholderId.Attributes["style"] = "display:none";

Anyway, as other have stated, your problems occurs because once you set control.visible = false, it doesn't get rendered in the client response.

IF your data includes an arbitrary sequence of blank characters (tab, space), and you want to replace each sequence with one comma, use the following:

sed 's/[\t ]+/,/g' input_file

or

sed -r 's/[[:blank:]]+/,/g' input_file

If you want to replace sequence of space characters, which includes other characters such as carriage return and backspace, etc, then use the following:

sed -r 's/[[:space:]]+/,/g' input_file

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

public class HtmlTextView extends AppCompatTextView {

public HtmlTextView(Context context) {
    super(context);
    init();
}

private void init(){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        setText(Html.fromHtml(getText().toString(), Html.FROM_HTML_MODE_COMPACT));
    } else {
        setText(Html.fromHtml(getText().toString()));
    }
 }
}

sometimes code is easier than words:

var func1 = function (x) { this.x = x; }                    // used with 'new' only
var func2 = function (x) { var z={}; z.x = x; return z; }   // used both ways
func1.prototype.y = 11;
func2.prototype.y = 12;

A1 = new func1(1);      // has A1.x  AND  A1.y
A2 =     func1(1);      // undefined ('this' refers to 'window')
B1 = new func2(2);      // has B1.x  ONLY
B2 =     func2(2);      // has B2.x  ONLY

for me, as long as I not prototype, I use style of func2 as it gives me a bit more flexibility inside and outside the function.

Tried your example

from . import config

got the following SystemError:
/usr/bin/python3.4 test.py
Traceback (most recent call last):
File "test.py", line 1, in
from . import config
SystemError: Parent module '' not loaded, cannot perform relative import

This will work for me:

import config
print('debug=%s'%config.debug)

>>>debug=True

Tested with Python:3.4.2 - PyCharm 2016.3.2

Beside this PyCharm offers you to Import this name.
You hav to click on config and a help icon appears.

If you still need to do this, I ran across the same problem. Somehow, EDGE renders all the scripts even if they are not via HTTP, HTTPS etc... Open the html/js file directly from the filesystem with Edge, and it will work.

Try this:

if cookie and not cookie.isspace():
    # the string is non-empty
else:
    # the string is empty

The above takes in consideration the cases where the string is None or a sequence of white spaces.

Here you go :

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/t", "", "");

Statement st = con.createStatement();
String sql = ("SELECT * FROM posts ORDER BY id DESC LIMIT 1;");
ResultSet rs = st.executeQuery(sql);
if(rs.next()) { 
 int id = rs.getInt("first_column_name"); 
 String str1 = rs.getString("second_column_name");
}

con.close();

In rs.getInt or rs.getString you can pass column_id starting from 1, but i prefer to pass column_name as its more informative as you don't have to look at database table for which index is what column.

UPDATE : rs.next

boolean next() throws SQLException

Moves the cursor froward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown. If the result set type is TYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will return false or throw an SQLException on a subsequent call to next.

If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

Returns: true if the new current row is valid; false if there are no more rows Throws: SQLException - if a database access error occurs or this method is called on a closed result set

I am using VS 2008 and I got this error. I tried everything else suggested here and on some other web sites but nothing worked.

The solution was quite simple and there were two other solutions mentioned on this page that put me in the right area.

1. Go to Project menu and click on Properties (you can also right click on the Project name in the Solution Explorer and select Properties).

2. Select Compile tab on the left.

3. In the "Build output path:" textbox make sure it that you have "bin\" in the textbox.

In my situation it was pointing to another bin folder on the network and that is what caused the breakpoints to fail. You want it looking at your project's current Bin folder.

Try this code

private void clearAppData() {
    try {
        if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager)getSystemService(ACTIVITY_SERVICE)).clearApplicationUserData();
        } else {
            Runtime.getRuntime().exec("pm clear " + getApplicationContext().getPackageName());
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

You may try;

$this->Output(/path/to/file);

So for you, it will be like;

$this->Output(/kuitit/);  //or try ("/kuitit/")

I'm not convinced its a good idea to return image data in a REST service. It ties up your application server's memory and IO bandwidth. Much better to delegate that task to a proper web server that is optimized for this kind of transfer. You can accomplish this by sending a redirect to the image resource (as a HTTP 302 response with the URI of the image). This assumes of course that your images are arranged as web content.

Having said that, if you decide you really need to transfer image data from a web service you can do so with the following (pseudo) code:

@Path("/whatever")
@Produces("image/png")
public Response getFullImage(...) {

    BufferedImage image = ...;

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ImageIO.write(image, "png", baos);
    byte[] imageData = baos.toByteArray();

    // uncomment line below to send non-streamed
    // return Response.ok(imageData).build();

    // uncomment line below to send streamed
    // return Response.ok(new ByteArrayInputStream(imageData)).build();
}

Add in exception handling, etc etc.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

You likely have other files (such as the default configuration) located in /etc/nginx/sites-enabled that needs to be removed.

This issue is caused by a repeat of the default_server parameter supplied to one or more listen directives in your files. You'll likely find this conflicting directive reads something similar to:

listen 80 default_server;

As the nginx core module documentation for listen states:

The default_server parameter, if present, will cause the server to become the default server for the specified address:port pair. If none of the directives have the default_server parameter then the first server with the address:port pair will be the default server for this pair.

This means that there must be another file or server block defined in your configuration with default_server set for port 80. nginx is encountering that first before your mysite.com file so try removing or adjusting that other configuration.

If you are struggling to find where these directives and parameters are set, try a search like so:

grep -R default_server /etc/nginx

why not using?

location.href='http://www.example.com';

The short answer, or TL;DR

Basically, eval is used to evaluate a single dynamically generated Python expression, and exec is used to execute dynamically generated Python code only for its side effects.

eval and exec have these two differences:

1. eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.

   An expression in Python is whatever you can have as the value in a variable assignment:

   a_variable = (anything you can put within these parentheses is an expression)
   

2. eval returns the value of the given expression, whereas exec ignores the return value from its code, and always returns None (in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).

In versions 1.0 - 2.7, exec was a statement, because CPython needed to produce a different kind of code object for functions that used exec for its side effects inside the function.

In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used.

Thus basically:

>>> a = 5
>>> eval('37 + a')   # it is an expression
42
>>> exec('37 + a')   # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47')   # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47')  # you cannot evaluate a statement
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    a = 47
      ^
SyntaxError: invalid syntax

The compile in 'exec' mode compiles any number of statements into a bytecode that implicitly always returns None, whereas in 'eval' mode it compiles a single expression into bytecode that returns the value of that expression.

>>> eval(compile('42', '<string>', 'exec'))  # code returns None
>>> eval(compile('42', '<string>', 'eval'))  # code returns 42
42
>>> exec(compile('42', '<string>', 'eval'))  # code returns 42,
>>>                                          # but ignored by exec

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval') This is where the difference really comes from.

If a code object (which contains Python bytecode) is passed to exec or eval, they behave identically, excepting for the fact that exec ignores the return value, still returning None always. So it is possible use eval to execute something that has statements, if you just compiled it into bytecode before instead of passing it as a string:

>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>

works without problems, even though the compiled code contains statements. It still returns None, because that is the return value of the code object returned from compile.

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

The longer answer, a.k.a the gory details

exec and eval

The exec function (which was a statement in Python 2) is used for executing a dynamically created statement or program:

>>> program = '''
for i in range(3):
    print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>> 

The eval function does the same for a single expression, and returns the value of the expression:

>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84

exec and eval both accept the program/expression to be run either as a str, unicode or bytes object containing source code, or as a code object which contains Python bytecode.

If a str/unicode/bytes containing source code was passed to exec, it behaves equivalently to:

exec(compile(source, '<string>', 'exec'))

and eval similarly behaves equivalent to:

eval(compile(source, '<string>', 'eval'))

Since all expressions can be used as statements in Python (these are called the Expr nodes in the Python abstract grammar; the opposite is not true), you can always use exec if you do not need the return value. That is to say, you can use either eval('my_func(42)') or exec('my_func(42)'), the difference being that eval returns the value returned by my_func, and exec discards it:

>>> def my_func(arg):
...     print("Called with %d" % arg)
...     return arg * 2
... 
>>> exec('my_func(42)')
Called with 42
>>> eval('my_func(42)')
Called with 42
84
>>> 

Of the 2, only exec accepts source code that contains statements, like def, for, while, import, or class, the assignment statement (a.k.a a = 42), or entire programs:

>>> exec('for i in range(3): print(i)')
0
1
2
>>> eval('for i in range(3): print(i)')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Both exec and eval accept 2 additional positional arguments - globals and locals - which are the global and local variable scopes that the code sees. These default to the globals() and locals() within the scope that called exec or eval, but any dictionary can be used for globals and any mapping for locals (including dict of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the executed code creates:

>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}

(If you display the value of the entire g, it would be much longer, because exec and eval add the built-ins module as __builtins__ to the globals automatically if it is missing).

In Python 2, the official syntax for the exec statement is actually exec code in globals, locals, as in

>>> exec 'global a; a, b = 123, 42' in g, l

However the alternate syntax exec(code, globals, locals) has always been accepted too (see below).

compile

The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1) built-in can be used to speed up repeated invocations of the same code with exec or eval by compiling the source into a code object beforehand. The mode parameter controls the kind of code fragment the compile function accepts and the kind of bytecode it produces. The choices are 'eval', 'exec' and 'single':

• 'eval' mode expects a single expression, and will produce bytecode that when run will return the value of that expression:

  >>> dis.dis(compile('a + b', '<string>', 'eval'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 RETURN_VALUE
  

• 'exec' accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None:

  >>> dis.dis(compile('a + b', '<string>', 'exec'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 POP_TOP                             <- discard result
                8 LOAD_CONST               0 (None)   <- load None on stack
               11 RETURN_VALUE                        <- return top of stack
  

• 'single' is a limited form of 'exec' which accepts a source code containing a single statement (or multiple statements separated by ;) if the last statement is an expression statement, the resulting bytecode also prints the repr of the value of that expression to the standard output(!).

  An if-elif-else chain, a loop with else, and try with its except, else and finally blocks is considered a single statement.

  A source fragment containing 2 top-level statements is an error for the 'single', except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:

  In Python 2.7.8:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  >>> a
  5
  

  And in Python 3.4.2:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 1
      a = 5
          ^
  SyntaxError: multiple statements found while compiling a single statement
  

  This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval the resulting code.

Thus greatest distinction of exec and eval actually comes from the compile function and its modes.

In addition to compiling source code to bytecode, compile supports compiling abstract syntax trees (parse trees of Python code) into code objects; and source code into abstract syntax trees (the ast.parse is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.

While eval only allows you to evaluate a string that contains a single expression, you can eval a whole statement, or even a whole module that has been compiled into bytecode; that is, with Python 2, print is a statement, and cannot be evalled directly:

>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print("Python is cool")
      ^
SyntaxError: invalid syntax

compile it with 'exec' mode into a code object and you can eval it; the eval function will return None.

>>> code = compile('for i in range(3): print("Python is cool")',
                   'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool

If one looks into eval and exec source code in CPython 3, this is very evident; they both call PyEval_EvalCode with same arguments, the only difference being that exec explicitly returns None.

Syntax differences of exec between Python 2 and Python 3

One of the major differences in Python 2 is that exec is a statement and eval is a built-in function (both are built-in functions in Python 3). It is a well-known fact that the official syntax of exec in Python 2 is exec code [in globals[, locals]].

Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec statement in CPython 2 can be also used with syntax that looks exactly like the exec function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals) built-in function! And that built-in function was replaced with exec statement somewhere before Python 1.0 release.

Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code was a tuple of length 2 or 3, and globals and locals were not passed into the exec statement otherwise, the code would be interpreted as if the 2nd and 3rd element of the tuple were the globals and locals respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:

The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals. The tuple form of exec provides compatibility with Python 3, where exec is a function rather than a statement.

Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.

Thus while exec is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,

>>> exec("print(a)", globals(), {'a': 42})
42

has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).

What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec into a variable:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
  File "<stdin>", line 1
    a = exec('print(42)')
           ^
SyntaxError: invalid syntax

(which wouldn't be useful in Python 3 either, as exec always returns None), or pass a reference to exec:

>>> call_later(exec, 'print(42)', delay=1000)
  File "<stdin>", line 1
    call_later(exec, 'print(42)', delay=1000)
                  ^
SyntaxError: invalid syntax

Which a pattern that someone might actually have used, though unlikely;

Or use it in a list comprehension:

>>> [exec(i) for i in ['print(42)', 'print(foo)']
  File "<stdin>", line 1
    [exec(i) for i in ['print(42)', 'print(foo)']
        ^
SyntaxError: invalid syntax

which is abuse of list comprehensions (use a for loop instead!).

let str = "{\"names\": [\"Bob\", \"Tim\", \"Tina\"]}"

let data = str.data(using: String.Encoding.utf8, allowLossyConversion: false)!

do {
    let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
    if let names = json["names"] as? [String] 
{
        print(names)
}
} catch let error as NSError {
    print("Failed to load: \(error.localizedDescription)")
}

If you want to grant to both tables and views try:

SELECT DISTINCT
    || OWNER
    || '.'
    || TABLE_NAME
    || ' to db_user;'
FROM
    ALL_TAB_COLS 
WHERE
    TABLE_NAME LIKE 'TABLE_NAME_%';

For just views try:

SELECT
    'grant select on '
    || OWNER
    || '.'
    || VIEW_NAME
    || ' to REPORT_DW;'
FROM
    ALL_VIEWS
WHERE
    VIEW_NAME LIKE 'VIEW_NAME_%';

Copy results and execute.

I did a small experiment of running a method "1,000,000,000 (one billion)" times with "Parallel.For" and one with "Task" objects.

I measured the processor time and found Parallel more efficient. Parallel.For divides your task in to small work items and executes them on all the cores parallely in a optimal way. While creating lot of task objects ( FYI TPL will use thread pooling internally) will move every execution on each task creating more stress in the box which is evident from the experiment below.

I have also created a small video which explains basic TPL and also demonstrated how Parallel.For utilizes your core more efficiently http://www.youtube.com/watch?v=No7QqSc5cl8 as compared to normal tasks and threads.

Experiment 1

Parallel.For(0, 1000000000, x => Method1());

Experiment 2

for (int i = 0; i < 1000000000; i++)
{
    Task o = new Task(Method1);
    o.Start();
}

You can use a CSS3 transition for this. Have a look at this example:

http://jsfiddle.net/ujDkf/1/

Here is the main code:

#box {
  position : relative;
  width : 100px;
  height : 100px;
  background-color : gray;
  border : 5px solid black;
  -webkit-transition : border 500ms ease-out;
  -moz-transition : border 500ms ease-out;
  -o-transition : border 500ms ease-out;
  transition : border 500ms ease-out;
}

#box:hover {
   border : 10px solid red;   
}

I would use itertools.chain - this will also cater for > 1 element in each sublist:

from itertools import chain
list(chain.from_iterable([[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]))

Without java code:

drawable/dotted.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">

    <stroke
       android:color="#FF00FF"
       android:dashWidth="10px"
       android:dashGap="10px"
       android:width="1dp"/>
</shape>

view.xml:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:src="@drawable/dotted"
    android:layerType="software" />

Effect:

if you want to do very quick plots with secondary Y-Axis then there is much easier way using Pandas wrapper function and just 2 lines of code. Just plot your first column then plot the second but with parameter secondary_y=True, like this:

df.A.plot(label="Points", legend=True)
df.B.plot(secondary_y=True, label="Comments", legend=True)

This would look something like below:

You can do few more things as well. Take a look at Pandas plotting doc.

Display Your Video First Frame as Thumbnail:

Add preload="metadata" to your video tag and the second of the first frame #t=0.5 to your video source:

<video width="400" controls="controls" preload="metadata">_x000D_
  <source src="https://www.w3schools.com/html/mov_bbb.mp4#t=0.5" type="video/mp4">_x000D_
</video>

Here I think it's worth mentioning SORT BY and ORDER BY both clauses and why they different,

SELECT * FROM <table_name> SORT BY <column_name> DESC LIMIT 2

If you are using SORT BY clause it sort data per reducer which means if you have more than one MapReduce task it will result partially ordered data. On the other hand, the ORDER BY clause will result in ordered data for the final Reduce task. To understand more please refer to this link.

SELECT * FROM <table_name> ORDER BY <column_name> DESC LIMIT 2

Note: Finally, Even though the accepted answer contains SORT BY clause, I mostly prefer to use ORDER BY clause for the general use case to avoid any data loss.

slicing operator. http://docs.python.org/tutorial/introduction.html#strings and scroll down a bit

This will work too!

foreach($data as &$value) {
  $value['transaction_date'] = date('d/m/Y', $value['transaction_date']);
}

Yay for alternatives!

Standard formats, with their related outputs,

Console.WriteLine("Standard Numeric Format Specifiers");
String s = String.Format("(C) Currency: . . . . . . . . {0:C}\n" +

The <TouchableHighlight> element is the source of the error. The <TouchableHighlight> element must have a child element.

Try running the code like this:

render() {
    const {height, width} = Dimensions.get('window');
    return (
        <View style={styles.container}>
            <Image 
                style={{
                    height:height,
                    width:width,
                }}
                source={require('image!foo')}
                resizeMode='cover' 
            />
            <TouchableHighlight style={styles.button}>
                <Text> This text is the target to be highlighted </Text>
            </TouchableHighlight>
        </View>
    );
}

private void replaceView(View oldV,View newV){
        ViewGroup par = (ViewGroup)oldV.getParent();
        if(par == null){return;}
        int i1 = par.indexOfChild(oldV);
        par.removeViewAt(i1);
        par.addView(newV,i1);
    }

Regexp way with list of values

SELECT * FROM table WHERE field regexp concat_ws("|",
"111",
"222",
"333");

Tutorial is not really required for this. Read up on encapsulation

private String myField; //"private" means access to this is restricted

public String getMyField()
{
     //include validation, logic, logging or whatever you like here
    return this.myField;
}
public void setMyField(String value)
{
     //include more logic
     this.myField = value;
}

I like to use the CPAN 'r' command for this. You can get into the CPAN shell with the old style:

sudo perl -MCPAN -e shell

or, on most newer systems, there is a 'cpan' command, so this command will get you to the shell:

sudo cpan

(You typically have to use 'sudo' to run it as root, or use 'su -' to become root before you run it, unless you have cpan set up to let you run it as a normal user, but install as root. If you don't have root on this machine, you can still use the CPAN shell to find out this information, but you won't be able to install modules, and you may have to go through a bit of setup the first time you run it.)

Then, once you're in the cpan shell, you can use the 'r' command to report all installed modules and their versions. So, at the "cpan>" prompt, type 'r'. This will list all installed modules and their versions. Use '?' to get some more help.

Since version 4.14 of Linux kernel, vfs_read and vfs_write functions are no longer exported for use in modules. Instead, functions exclusively for kernel's file access are provided:

# Read the file from the kernel space.
ssize_t kernel_read(struct file *file, void *buf, size_t count, loff_t *pos);

# Write the file from the kernel space.
ssize_t kernel_write(struct file *file, const void *buf, size_t count,
            loff_t *pos);

Also, filp_open no longer accepts user-space string, so it can be used for kernel access directly (without dance with set_fs).

If jQuery is loading asynchronously, you can wait till it is defined, checking for it every period of time:

(function() {
    var a = setInterval( function() {
        if ( typeof window.jQuery === 'undefined' ) {
            return;
        }
        clearInterval( a );

        console.log( 'jQuery is loaded' ); // call your function with jQuery instead of this
    }, 500 );
})();

This method can be used for any variable, you are waiting to appear.

just a moment ago, i came across with the same issue. and i resolve it in the following manner.

Response.Redirect("../index.aspx?Name="+this.textName.Text+"&LastName="+this.textlName.Text);
