I don't understand exactly what your code is trying to do, but you can make variables available in any event handler using the advantages of function closures:

function addClickHandler(elem, arg1, arg2) {
    elem.addEventListener('click', function(e) {
        // in the event handler function here, you can directly refer
        // to arg1 and arg2 from the parent function arguments
    }, false);
}

Depending upon your exact coding situation, you can pretty much always make some sort of closure preserve access to the variables for you.

From your comments, if what you're trying to accomplish is this:

element.addEventListener('click', func(event, this.elements[i]))

Then, you could do this with a self executing function (IIFE) that captures the arguments you want in a closure as it executes and returns the actual event handler function:

element.addEventListener('click', (function(passedInElement) {
    return function(e) {func(e, passedInElement); };
}) (this.elements[i]), false);

For more info on how an IIFE works, see these other references:

Javascript wrapping code inside anonymous function

Immediately-Invoked Function Expression (IIFE) In JavaScript - Passing jQuery

What are good use cases for JavaScript self executing anonymous functions?

This last version is perhaps easier to see what it's doing like this:

// return our event handler while capturing an argument in the closure
function handleEvent(passedInElement) {
    return function(e) {
        func(e, passedInElement); 
    };
}

element.addEventListener('click', handleEvent(this.elements[i]));

It is also possible to use .bind() to add arguments to a callback. Any arguments you pass to .bind() will be prepended to the arguments that the callback itself will have. So, you could do this:

elem.addEventListener('click', function(a1, a2, e) {
    // inside the event handler, you have access to both your arguments
    // and the event object that the event handler passes
}.bind(elem, arg1, arg2));

You can use:

 Handler handler = new Handler()
 handler.postDelayed(new Runnable())

Or you can use:

 handler.removeCallbacksAndMessages(null);

Docs

public final void removeCallbacksAndMessages (Object token)

Added in API level 1 Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

Or you could also do like the following:

Handler handler =  new Handler()
Runnable myRunnable = new Runnable() {
public void run() {
    // do something
}
};
handler.postDelayed(myRunnable,zeit_dauer2);

Then:

handler.removeCallbacks(myRunnable);

Docs

public final void removeCallbacks (Runnable r)

Added in API level 1 Remove any pending posts of Runnable r that are in the message queue.

public final void removeCallbacks (Runnable r, Object token)

Edit:

Change this:

@Override
public void onClick(View v) {
    Handler handler =  new Handler();
    Runnable myRunnable = new Runnable() {

To:

@Override
public void onClick(View v) {
    handler = new Handler();
    myRunnable = new Runnable() { /* ... */}

Because you have the below. Declared before onCreate but you re-declared and then initialized it in onClick leading to a NPE.

Handler handler; // declared before onCreate
Runnable myRunnable;

Does document.getElementById("blue") exist? if it doesn't then blue_box will be equal to null. you can't set a onclick on something that's null

You can use this for Simplest Solution:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Write your code here
    }
}, 5000); //Timer is in ms here.

Else, Below can be another clean useful solution:

new Handler().postDelayed(() -> 
{/*Do something here*/}, 
5000); //time in ms

.on() is for jQuery version 1.7 and above. If you have an older version, use this:

$("#SomeId").live("click",function(){
    //do stuff;
});

var module = angular.module('testApp', [])
    .directive('onFinishRender', function ($timeout) {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            if (scope.$last === true) {
                $timeout(function () {
                    scope.$emit(attr.onFinishRender);
                });
            }
        }
    }
});

Notice that I didn't use .ready() but rather wrapped it in a $timeout. $timeout makes sure it's executed when the ng-repeated elements have REALLY finished rendering (because the $timeout will execute at the end of the current digest cycle -- and it will also call $apply internally, unlike setTimeout). So after the ng-repeat has finished, we use $emit to emit an event to outer scopes (sibling and parent scopes).

And then in your controller, you can catch it with $on:

$scope.$on('ngRepeatFinished', function(ngRepeatFinishedEvent) {
    //you also get the actual event object
    //do stuff, execute functions -- whatever...
});

With html that looks something like this:

<div ng-repeat="item in items" on-finish-render="ngRepeatFinished">
    <div>{{item.name}}}<div>
</div>

What you want is an implementation of the observer pattern. You can do it yourself completely, or use java classes like java.util.Observer and java.util.Observable

Of course you can use floats or doubles for "critical" things ... Many applications do nothing but crunch numbers using these datatypes.

You might have misunderstood some of the various caveats regarding floating-point numbers, such as the recommendation to never compare for exact equality, and so on.

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:

Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:

flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only

Then you can fix it by running the following commands:

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

PowerShell 5.0

From Microsoft.PowerShell.Archive you can use:

• Compress-Archive
• Expand-Archive

E.g.:

• Create result.zip from the entire Test folder:

  Compress-Archive -Path C:\Test -DestinationPath C:\result
  

• Extract the content of result.zip in the specified Test folder:

  Expand-Archive -Path result.zip -DestinationPath C:\Test
  

Very simple :

It's my tips

Make sure in your controller that you have your http attribute like:

[HttpPost]

also add the attribute in the controller:

[ValidateAntiForgeryToken]

In your form on your view you have to write:

@Html.AntiForgeryToken();

I had Html.AntiForgeryToken(); without the @ sign while it was in a code block, it didn't give an error in Razor but did at runtime. Make sure you look at the @ sign of @Html.Ant.. if it is missing or not

No more than this IMHO - you can add the upper or lower methods

def count_letter_in_str(string,letter):
    return string.count(letter)

group by fV.tier_id, f.form_template_id

It's a long pointer to a constant, wide string (i.e. a string of wide characters).

Since it's a wide string, you want to make your constant look like: L"TestWindow". I wouldn't create the intermediate a either, I'd just pass L"TestWindow" for the parameter:

ghTest = FindWindowEx(NULL, NULL, NULL, L"TestWindow");

If you want to be pedantically correct, an "LPCTSTR" is a "text" string -- a wide string in a Unicode build and a narrow string in an ANSI build, so you should use the appropriate macro:

ghTest = FindWindow(NULL, NULL, NULL, _T("TestWindow"));

Few people care about producing code that can compile for both Unicode and ANSI character sets though, and if you don't getting it to really work correctly can be quite a bit of extra work for little gain. In this particular case, there's not much extra work, but if you're manipulating strings, there's a whole set of string manipulation macros that resolve to the correct functions.

Mad a similar error, easy to fix:

    TypeError Traceback (most recent call last) <ipython-input-2-1eb12bfdc7db> in <module>
  3 mylist = [10,20,30] ----> 4 arr = np.array[(10,20,30)] 5 d = {'a':10, 'b':20, 'c':30} TypeError: 'builtin_function_or_method' object is not subscriptable

but I should have written it as:

arr = np.array([10,20,30])

Very fixable, rookie/dumb mistake.

Here's a compact way to do something different in all four cases:

if(empty($youtube)) {
    if(empty($link)) {
        # both empty
    } else {
        # only $youtube not empty
    }
} else {
    if(empty($link)) {
        # only $link empty
    } else {
        # both not empty
    }
}

If you want to use an expression instead, you can use ?: instead:

echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
                     : ( empty($link) ? 'only $link empty' : 'both not empty' );

Applies to .NET Core 1 and .Net Core 2 (further down)

If using .Net-Core 1.1

Unfortunately the docs are very confusing in this specific case. So I'll make it dead-simple:

• Add Microsoft.AspNetCore.Cors nuget package to your project
• In ConfigureServices method, add services.AddCors();

• In Configure method, before calling app.UseMvc() and app.UseStaticFiles(), add:

  app.UseCors(builder => builder
      .AllowAnyOrigin()
      .AllowAnyMethod()
      .AllowAnyHeader()
      .AllowCredentials());
  

That's it. Every client has access to your ASP.NET Core Website/API.

If using .Net-Core 2.0

• Add Microsoft.AspNetCore.Cors nuget package to your project

• in ConfigureServices method, before calling services.AddMvc(), add:

   services.AddCors(options =>
      {
          options.AddPolicy("AllowAll",
              builder =>
              {
                  builder
                  .AllowAnyOrigin() 
                  .AllowAnyMethod()
                  .AllowAnyHeader()
                  .AllowCredentials();
              });
      });
  

• (Important) In Configure method, before calling app.UseMvc(), add app.UseCors("AllowAll");

  AllowAll is the policy name which we need to mention in app.UserCors. It could be any name.

Here's an example of the remote-fetch-merge.

cd /home/you/projectA
git remote add projectB /home/you/projectB
git fetch projectB

Then you can:

git cherry-pick <first_commit>..<last_commit>

or you could even merge the whole branch

git merge projectB/master

well there are really enough examples for this, but anyway, here you go

as a side note: the calls to Encrypt() and Decrypt() have a bool parameter that switches between OAEP and PKCS#1.5 padding ... you might want to choose OAEP if it's available in your situation

Another option that may be suitable in this situation is using XML

The XML option to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation. 

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

Vertical expansion

Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

Horizontal expansion

Unlike the PIVOT, newly added documents can be displayed without altering the script.

Performance breakdown

In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

Using onScrollChangeListener (works on API 23):

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        scrollView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
            @Override
            public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {

                int bottom =   (scrollView.getChildAt(scrollView.getChildCount() - 1)).getHeight()-scrollView.getHeight()-scrollY;

                if(scrollY==0){
                    //top detected
                }
                if(bottom==0){
                    //bottom detected
                }
            }
        });
    }

using scrollChangeListener on TreeObserver

 scrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
        @Override
        public void onScrollChanged() {
            int bottom =   (scrollView.getChildAt(scrollView.getChildCount() - 1)).getHeight()-scrollView.getHeight()-scrollView.getScrollY();

            if(bottom==0) {
                //bottom detected
            }
        }
    });

Hope this solution helps :)

You can use rename utility to rename multiple files by a pattern. For example following command will prepend string MyVacation2011_ to all the files with jpg extension.

rename 's/^/MyVacation2011_/g' *.jpg

or

rename <pattern> <replacement> <file-list>

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This is how I made my Application Class

    [Application]
    public class Application : Android.App.Application, IApplication
    {
        public Application(IntPtr handle, JniHandleOwnership transfer) : base(handle, transfer)
        {

        }
        public object MyObject { get; set; }
    }

2x faster than the versions before mentioned - mostly because transform() and inner_product() loops are joined. Sorry about my shortcut/typedefs/macro: Flo = float. CR const ref. VFlo - vector. Tested in VS2010

#define fe(EL, CONTAINER)   for each (auto EL in CONTAINER)  //VS2010
Flo stdDev(VFlo CR crVec) {
    SZ  n = crVec.size();               if (n < 2) return 0.0f;
    Flo fSqSum = 0.0f, fSum = 0.0f;
    fe(f, crVec) fSqSum += f * f;       // EDIT: was Cit(VFlo, crVec) {
    fe(f, crVec) fSum   += f;
    Flo fSumSq      = fSum * fSum;
    Flo fSumSqDivN  = fSumSq / n;
    Flo fSubSqSum   = fSqSum - fSumSqDivN;
    Flo fPreSqrt    = fSubSqSum / (n - 1);
    return sqrt(fPreSqrt);
}

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

• ViewParam vs @ManagedProperty(value = "#{param.id}")

Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:

1. Ctrl-G
2. A1:X50 Enter
3. Delete

Unless you have to do this very often, entering and then triggering the VBAcode is more effort.

And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S to select Goto Special and here select Formulas or Values.

You confuse an abstract stack and the hardware implemented stack. The latter is already implemented.

I solved this problem by searching "mvc". The System.Web.Mvc appeared in search results, despite it is not contained in the list.

If you need to get datetime.time value, you can use this trick:

my_time = (datetime(1970,1,1) + timedelta(seconds=my_seconds)).time()

You cannot add timedelta to time, but can add it to datetime.

UPD: Yet another variation of the same technique:

my_time = (datetime.fromordinal(1) + timedelta(seconds=my_seconds)).time()

Instead of 1 you can use any number greater than 0. Here we use the fact that datetime.fromordinal will always return datetime object with time component being zero.

Having some experience of this, you can indeed use C++ code for your "core" code, but you have to use objective-C for anything iPhone specific.

Don't try to force Objective-C to act like C++. At first it will seem to you this is possible, but the resulting code really won't work well with Cocoa, and you will get very confused as to what is going on. Take the time to learn properly, without any C++ around, how to build GUIs and iPhone applications, then link in your C++ base.

I have an example which I have been using for couple years. Please take a look as a reference.

David Brabant's answer led me to what I needed, with this addition:

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

Here is the way I got that:

@Component
public class ApplicationStartup implements ApplicationListener<ApplicationReadyEvent> {

    /**
     * This event is executed as late as conceivably possible to indicate that
     * the application is ready to service requests.
     */

    @Autowired
    private MovieRepositoryImpl movieRepository;

    @Override
    public void onApplicationEvent(final ApplicationReadyEvent event) {
        seedData();
    }

    private void seedData() {
        movieRepository.save(new Movie("Example"));

        // ... add more code
    }

}

boolean isn't a distinct datatype in MySQL; it's just a synonym for tinyint. See this page in the MySQL manual.

Personally I would suggest use tinyint as a preference, because boolean doesn't do what you think it does from the name, so it makes for potentially misleading code. But at a practical level, it really doesn't matter -- they both do the same thing, so you're not gaining or losing anything by using either.

Since release r59, three.js provides those three functions to rotate a object around object axis.

object.rotateX(angle);
object.rotateY(angle);
object.rotateZ(angle);

if we are using XDocument.Parse(@""). Use @ it resolves the issue.

That looks like you tried to add the libraries servlet.jar or servlet-api.jar into your project /lib/ folder, but Tomcat already should provide you with those libraries. Remove them from your project and classpath. Search for that anywhere in your project or classpath and remove it.

Your method signature is:

- (void) myTest:(NSString *)

withAString happens to be the parameter (the name is misleading, it looks like it is part of the selector's signature).

If you call the function in this manner:

[self performSelector:@selector(myTest:) withObject:myString];

It will work.

But, as the other posters have suggested, you may want to rename the method:

- (void)myTestWithAString:(NSString*)aString;

And call:

[self performSelector:@selector(myTestWithAString:) withObject:myString];

The split work until 4000 chars depending on the characters that you are inserting. If you are inserting special characters it can fail. The only secure way is to declare a variable.

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

reinterpret_cast cannot be used for this conversion, the code will not compile. According to C++03 standard section 5.2.10-1:

Conversions that can be performed explicitly using reinterpret_cast are listed below. No other conversion can be performed explicitly using reinterpret_cast.

This conversion is not listed in that section. Even this is invalid:

long l = reinterpret_cast<long>(i)

static_cast is the one which has to be used here. See this and this SO questions.

In HTML ids should be unique. I suggest you change your code to something like this:

<div id="div1" >
    <input type="text" name="edit1" id="edit1" />
    <input type="text" name="edit2" id="edit2" />
</div>
<div id="div2" >
    <input type="text" name="edit1" id="edit3" />
    <input type="text" name="edit2" id="edit4" />
</div>

There's a whole API for managing portfolios. *Link removed. Google no longer provides a developer API for this.

Getting stock quotes is a little harder. I found one article where someone got stock quotes using Google Spreadsheets.

You can also use the gadgets but I guess that's not what you're after.

The API you mention is interesting but doesn't seem to be documented (as far as I've been able to find anyway).

Here is some information on historical prices, just for reference sake.

i see here already wrote good answers, but sometime to write the same in other form can be helpful

<div ng-app ng-controller="MyCtrl">
  <select ng-model="referral.organization" ng-options="c for c in organizations"></select>
</div>

<script type='text/javascript'>
  function MyCtrl($scope) {
    $scope.organizations = ['a', 'b', 'c', 'd', 'e'];
    $scope.referral = {
      organization: $scope.organizations[2]
    };
  }
</script>

In Windows, with GetFileInformationByHandleEx, passing FileNameInfo, you can retrieve the file name.

I think only push operation suffers, is enough. My implementation includes a stack of nodes. Each node contain the data item and also the minimum on that moment. This minimum is updated each time a push operation is done.

Here are some points for understanding:

• I implemented the stack using Linked List.

• A pointer top always points to the last pushed item. When there is no item in that stack top is NULL.

• When an item is pushed a new node is allocated which has a next pointer that points to the previous stack and top is updated to point to this new node.

Only difference with normal stack implementation is that during push it updates a member min for the new node.

Please have a look at code which is implemented in C++ for demonstration purpose.

/*

Ok, here is a fetch DELETE example too:

When CPU/math computing power is limited:

There are times (such as in my work) when computing power is scarce (e.g. no floating point processor, working with small microcontrollers) where some trig functions can take an exorbitant amount of CPU time (e.g. 3000+ clock cycles), so when I only need an approximation, especially if if the CPU must not be tied up for a long time, I use this to minimize CPU overhead:

/**------------------------------------------------------------------------

1. Install android sdk manager
2. check if building tools installed. install api 23.
3. from the Android SDK Manager download the 'Android Support Repository'
4. remove cordova-plugin-android-support-v4
5. build

It's still not possible.

Be sure that your actual repo is the lastest version

1. Edit .gitignore as you wish
2. git rm -r --cached . (remove all files)
3. git add . (re-add all files)

then commit as usual

You are better off using an iterator instead. Relevant: http://docs.python.org/library/fileinput.html

From the docs:

import fileinput
for line in fileinput.input("filename"):
    process(line)

This will avoid copying the whole file into memory at once.

There's a much easier way to do this, using iconv - from the user notes, this seems to be what you want to do: characters transliteration

// PHP.net User notes
<?php
    $string = "?ABBASABAD";

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $string);
    // output: [nothing, and you get a notice]

    echo iconv('UTF-8', 'ISO-8859-1//IGNORE', $string);
    // output: ABBSBD

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
    // output: ABBASABAD
    // Yay! That's what I wanted!
?>

Be very conscientious with your character encodings, so you are keeping the same encoding at all stages in the process - front end, form submission, encoding of the source files. Default encoding in PHP and in forms is ISO-8859-1, before PHP 5.4 where it changed to be UTF8 (finally!).

There's a couple of functions you can play around with for ideas. First is from CakePHP's inflector class, called slug:

public static function slug($string, $replacement = '_') {
    $quotedReplacement = preg_quote($replacement, '/');

    $merge = array(
        '/[^\s\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}]/mu' => ' ',
        '/\\s+/' => $replacement,
        sprintf('/^[%s]+|[%s]+$/', $quotedReplacement, $quotedReplacement) => '',
    );

    $map = self::$_transliteration + $merge;
    return preg_replace(array_keys($map), array_values($map), $string);
}

It depends on a self::$_transliteration array which is similar to what you were doing in your question - you can see the source for inflector on github.

Another is a function I use personally, which comes from here.

function slugify($text,$strict = false) {
    $text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
    // replace non letter or digits by -
    $text = preg_replace('~[^\\pL\d.]+~u', '-', $text);

    // trim
    $text = trim($text, '-');
    setlocale(LC_CTYPE, 'en_GB.utf8');
    // transliterate
    if (function_exists('iconv')) {
        $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    }

    // lowercase
    $text = strtolower($text);
    // remove unwanted characters
    $text = preg_replace('~[^-\w.]+~', '', $text);
    if (empty($text)) {
        return 'empty_$';
    }
    if ($strict) {
        $text = str_replace(".", "_", $text);
    }
    return $text;
}

What those functions do is transliterate and create 'slugs' from arbitrary text input, which is a very very useful thing to have in your toolchest when making web apps. Hope this helps!

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.

this code works for me (Python3-compatible):

def chunkify(tab, num):
    return [tab[i*num: i*num+num] for i in range(len(tab)//num+(1 if len(tab)%num else 0))]

example (for bytearray type, but it works for lists as well):

b = bytearray(b'\x01\x02\x03\x04\x05\x06\x07\x08')
>>> chunkify(b,3)
[bytearray(b'\x01\x02\x03'), bytearray(b'\x04\x05\x06'), bytearray(b'\x07\x08')]
>>> chunkify(b,4)
[bytearray(b'\x01\x02\x03\x04'), bytearray(b'\x05\x06\x07\x08')]

If you are using visual studio 2005 then

public void sumAverageElements(int[] arr)
{
     int size =arr.Length;
     int sum = 0;
     int average = 0;

     for (int i = 0; i < size; i++)
     {
          sum += arr[i];
     }

     average = sum / size; // sum divided by total elements in array

     Console.WriteLine("The Sum Of Array Elements Is : " + sum);
     Console.WriteLine("The Average Of Array Elements Is : " + average);
}

I am using latest swift (2.1) and the answer (Dharmesh Kheni and jungledev) does not work for me. The image color was off (when setting in IB, it was blue and when setting directly in UIButton, it was black). It turns out I could create the same bar item with the following code:

let barButton = UIBarButtonItem(image: UIImage(named: "menu"), landscapeImagePhone: nil, style: .Done, target: self, action: #selector(revealBackClicked))
self.navigationItem.leftBarButtonItem = barButton

Clustering aims at finding groups in data. “Cluster” is an intuitive concept and does not have a mathematically rigorous definition. The members of one cluster should be similar to one another and dissimilar to the members of other clusters. A clustering algorithm operates on an unlabeled data set Z and produces a partition on it.

For Classes and Class Labels, class contains similar objects, whereas objects from different classes are dissimilar. Some classes have a clear-cut meaning, and in the simplest case are mutually exclusive. For example, in signature verification, the signature is either genuine or forged. The true class is one of the two, no matter that we might not be able to guess correctly from the observation of a particular signature.

Swift 3

if yourArray.contains(item) {
   //item found, do what you want
}
else{
   //item not found 
   yourArray.append(item)
}

window.location adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.

window.location.replace replaces the current history item so you can't go back to it.

See window.location:

assign(url): Load the document at the provided URL.

replace(url):Replace the current document with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

Oh and generally speaking:

window.location.href = url;

is favoured over:

window.location = url;

Add disabled Class in your anchor, following are js:

$('.navbar .dropdown-toggle').hover(function() {
  $(this).addClass('disabled');
});

But this is not mobile friendly so you need to remove disabled class for mobile, so updated js code is following:

$('.navbar .dropdown-toggle').hover(function() {
  if (document.documentElement.clientWidth > 769) { $(this).addClass('disabled');}
  else { $(this).removeClass('disabled'); }
});

Top answers have several disadvantages: you have to add new layout paths, AS places new resources to res\layouts folder instead of res\values.

Combining several answers I wrote similar:

sourceSets {
    main {
        res.srcDirs =
                [
                        'src/main/res',
                        file("src/main/res/layouts/").listFiles(),
                        'src/main/res/layouts'
                ]
    }
}

I made folders with this article: http://alexzh.com/tutorials/how-to-store-layouts-in-different-folders-in-android-project/. In order to create subfolders you should use this menu: New > Folder > Res Folder.

UPDATE

After a couple of weeks I found that changes in resources are not noticed by Android Studio. So, some weird bugs appear. For instance, layouts continue to show old sizes, margins. Sometimes AS doesn't find new XML-files (especially during run-time). Sometimes it mixes view ids (references to another XML-file). It's often required to press Build > Clean Project or Build > Rebuild Project. Read Rebuild required after changing xml layout files in Android Studio.

To vertically center a span or div element within another div, add position relative to parent div and position absolute to the child div.Now the child div can be positioned anywhere inside the div.Example below centers both horizontally and vertically.

<div class="parent">
    <div class="child">Vertically and horizontally centered child div</div>
</div>

css:

.parent{
    position: relative;
}
.child{
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

The solution is much too big. Try this simple one. Please provide a 7+ character buffer, no check made.

char *i2str(int i, char *buf){
  byte l=0;
  if(i<0) buf[l++]='-';
  boolean leadingZ=true;
  for(int div=10000, mod=0; div>0; div/=10){
    mod=i%div;
    i/=div;
    if(!leadingZ || i!=0){
       leadingZ=false;
       buf[l++]=i+'0';
    }
    i=mod;
  }
  buf[l]=0;
  return buf;
}

Can be easily modified to give back end of buffer, if you discard index 'l' and increment the buffer directly.

Define the Private variables

Inside the Constructor and load the data

I have created Constant and load the data from constant to Selected List class.

public  class GridModel
{
    private IEnumerable<SelectList> selectList;
    private IEnumerable<SelectList> Roles;

    public GridModel()
    {
        selectList = from PageSizes e in Enum.GetValues(typeof(PageSizes))
                       select( new SelectList()
                       {
                           Id = (int)e,
                           Name = e.ToString()
                       });

        Roles= from Userroles e in Enum.GetValues(typeof(Userroles))
               select (new SelectList()
               {
                   Id = (int)e,
                   Name = e.ToString()
               });
    }

  public IEnumerable<SelectList> Pagesizelist { get { return this.selectList; } set { this.selectList = value; } } 
  public IEnumerable<SelectList> RoleList { get { return this.Roles; } set { this.Roles = value; } }
  public IEnumerable<SelectList> StatusList { get; set; }

}

Starting with the System.IO namespace (particularly the File or FileInfo objects) should get you started.

There is a blog post on MSDN about why an exponent operator does NOT exists from the C# team.

It would be possible to add a power operator to the language, but performing this operation is a fairly rare thing to do in most programs, and it doesn't seem justified to add an operator when calling Math.Pow() is simple.

You asked:

Do I have to write a loop or include another namespace to handle exponential operations? If so, how do I handle exponential operations using non-integers?

Math.Pow supports double parameters so there is no need for you to write your own.

I use the following directive that makes me and most users very happy! It uses moment for parsing and formatting. It looks a little bit like the one by SunnyShah, mentioned earlier.

angular.module('app.directives')

.directive('appDatetime', function ($window) {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function (scope, element, attrs, ngModel) {
            var moment = $window.moment;

            ngModel.$formatters.push(formatter);
            ngModel.$parsers.push(parser);

            element.on('change', function (e) {
                var element = e.target;
                element.value = formatter(ngModel.$modelValue);
            });

            function parser(value) {
                var m = moment(value);
                var valid = m.isValid();
                ngModel.$setValidity('datetime', valid);
                if (valid) return m.valueOf();
                else return value;
            }

            function formatter(value) {
                var m = moment(value);
                var valid = m.isValid();
                if (valid) return m.format("LLLL");
                else return value;

            }

        } //link
    };

}); //appDatetime

In my form i use it like this:

<label>begin: <input type="text" ng-model="doc.begin" app-datetime required /></label>
<label>end: <input type="text" ng-model="doc.end" app-datetime required /></label>

This will bind a timestamp (milliseconds since 1970) to doc.begin and doc.end.

Andreas Lundgren's answer worked and I was able to compile and run my app.

However, when I tried to run the project's associated JUnit tests I received the same error. Running

gradle -version

from Windows command prompt showed that gradle was still picking up the incorrect jdk. To fix it I had to set the JAVA_HOME environment variable to point to the correct jdk and restart IntelliJ.

If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)

1. go the directory where NodeJS was installed
2. find file nodevars.bat
3. open it with editor as administrator

4. change the default path in the row which looks like

   if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
   

with your path. It could be for example

    if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"

if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:

     cd c:/MyDirectory/

I faced this while I was using ASP .NET Forms. The solution I used was deleting or commenting out jQuery and Bootstrap references from the <asp:ScriptManager runat="server"> in the master page. It seems it creates a conflict with the jQuery and Bootstrap references that you put in the <header>.

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

According to WikiPedia, you can specify which favicon file to load using the link tag in the head section, with a parameter of rel="icon".

For example:

 <link rel="icon" type="image/png" href="/path/image.png">

I imagine if you wanted to write some dynamic content for that call, you would have access to cookies so you could retrieve your session information that way and present appropriate content.

You may fall foul of file formats (IE reportedly only supports it's .ICO format, whilst most everyone else supports PNG and GIF images) and possibly caching issues, both on the browser and through proxies. This would be because of the original itention of favicon, specifically, for marking a bookmark with a site's mini-logo.

In the new ES2015 standard for JavaScript (formerly called ES6), objects can be created with computed keys: Object Initializer spec.

The syntax is:

var obj = {
  [myKey]: value,
}

If applied to the OP's scenario, it would turn into:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    return {
      [this.attr('name')]: this.attr('value'),
    };
  }) 

  callback(null, inputs);
}

Note: A transpiler is still required for browser compatiblity.

Using Babel or Google's traceur, it is possible to use this syntax today.

In earlier JavaScript specifications (ES5 and below), the key in an object literal is always interpreted literally, as a string.

To use a "dynamic" key, you have to use bracket notation:

var obj = {};
obj[myKey] = value;

In your case:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    var key   = this.attr('name')
     ,  value = this.attr('value')
     ,  ret   = {};

     ret[key] = value;
     return ret;
  }) 

  callback(null, inputs);
}

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

Our js-programmer asked me to return the exact JSON format data instead of a json-encoded string to her.

Below is the solution.(This will return an object that can be used/viewed straightly in the browser)

import json
from xxx.models import alert
from django.core import serializers

def test(request):
    alert_list = alert.objects.all()

    tmpJson = serializers.serialize("json",alert_list)
    tmpObj = json.loads(tmpJson)

    return HttpResponse(json.dumps(tmpObj))

Apply DataAnnotation like:

[DisplayFormat(DataFormatString = "{0:MMM dd, yyyy}")]

Number (2) is possible by using a socket implementation (like websocket, socket.io, etc.) with a custom heartbeat for each session the user is engaged in. If a user attempts to open another window, you have a javascript handler check with the server if it's ok, and then respond with an error messages.

However, a better solution is to synchronize the two sessions if possible like in google docs.

instanceof also works when callback is a subtype of Function, I think

If you use MyISAM tables, then you can recover any data you deleted, just

open file: mysql/data/[your_db]/[your_table].MYD

with any text editor

The second one:

word.contains("\n");

If you want to do something x times, you can do this:

Example (x = 200):

FOR /L %%A IN (1,1,200) DO (
  ECHO %%A
)

1,1,200 means:

• Start = 1
• Increment per step = 1
• End = 200

I think this gives you the total list of all files in the repo history:

git rev-list --objects --all | git cat-file --batch-check="%(objectsize) %(rest)" | cut -d" " -f1 | paste -s -d + - | bc

You can replace --all with a treeish (HEAD, origin/master, etc.) to calculate the size of a branch.

I suggest, never delete data. Don't say if the tables is longer than 1000 truncate the end of the table. There needs to be real business logic in your plan like how long has this user been inactive. For example, if it is longer than 1 year then put them in a different table. You would have this happen weekly or monthly in a maintenance script in the middle of a slow time.

When you run into to many rows in your table then you should start sharding the tables or partitioning and put old data in old tables by year such as users_2011_jan, users_2011_feb or use numbers for the month. Then change your programming to work with this model. Maybe make a new table with less information to summarize the data in less columns and then only refer to the bigger partitioned tables when you need more information such as when the user is viewing their profile. All of this should be considered very carefully so in the future it isn't too expensive to re-factor. You could also put only the users which comes to your site all the time in one table and the users that never come in an archived set of tables.

This assumes you know the position of the element in the ListView :

  View element = listView.getListAdapter().getView(position, null, null);

Then you should be able to call getLeft() and getTop() to determine the elements on screen position.

Just be careful. You will get this message if you try to enter a command that doesn't exist like this

/usr/bin/java -v

Try something like this:

$link = @new mysqli($this->host, $this->user, $this->pass)
$statement = $link->prepare($sqlStatement);
                if(!$statement)
                {
                    $this->debug_mode('query', 'error', '#Query Failed<br/>' . $link->error);
                    return false;
                }

You can use Mono to run ASP.NET applications on Apache/Linux, however it has a limited subset of what you can do under Windows. As for "they" saying Windows is more vulnerable to attack - it's not true. IIS has had less security problems over the last couple of years that Apache, but in either case it's all down to the administration of the boxes - both OSes can be easily secured. These days the attack points are not the OS or web server software, but the applications themselves.

Check out this GitHub repository that describes best practices for AngularJS apps. It has naming conventions for different components. It is not complete, but it is community-driven so everyone can contribute.

getJSON() will also parse the JSON for you after fetching, so from then on, you are working with a simple Javascript array ([] marks an array in JSON). The documentation also has examples on how to handle the fetched data.

You can get all the values in an array using a for loop:

$.getJSON("url_with_json_here", function(data){
    for (var i = 0, len = data.length; i < len; i++) {
        console.log(data[i]);
    }
});

Check your console to see the output (Chrome, Firefox/Firebug, IE).

jQuery also provides $.each() for iterations, so you could also do this:

$.getJSON("url_with_json_here", function(data){
    $.each(data, function (index, value) {
        console.log(value);
    });
});

Using LINQ your query should look something like this:

public User GetUser(int userID){

return
(
 from p in "MyTable" //(Your Entity Model)
 where p.UserID == userID
 select p.Name
).SingleOrDefault();

}

Of course to do this you need to have an ADO.Net Entity Model in your solution.

You can programatically change it by setting the system property:

public class App {

    public static void main(String[] args) {

        System.setProperty(org.slf4j.impl.SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "TRACE");

        final org.slf4j.Logger log = LoggerFactory.getLogger(App.class);

        log.trace("trace");
        log.debug("debug");
        log.info("info");
        log.warn("warning");
        log.error("error");

    }
}

The log levels are ERROR > WARN > INFO > DEBUG > TRACE.

Please note that once the logger is created the log level can't be changed. If you need to dynamically change the logging level you might want to use log4j with SLF4J.

I was able to implement DELETE operation with a Request body. I used AWS Lambda and AWS API gateway and used Go language.

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

Just use this line

svn update -r yourOldRevesion

You can know your current revision by using:

svn info

android:maxLines="1"
android:inputType="text"

Add the above code to have a single line in EditText tag in your layout.

android:singleLine="true" is deprecated

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

Valerio is almost right with his solution, but there is some logical mistake.

you must firstly check wether angle2 is bigger than angle, before adding 360 at a negative.

otherwise you always have a bigger value than angle

So the correct solution is:

var west = calculateMin(data.longitudes);
var east = calculateMax(data.longitudes);
var angle = east - west;
var north = calculateMax(data.latitudes);
var south = calculateMin(data.latitudes);
var angle2 = north - south;
var zoomfactor;
var delta = 0;
var horizontal = false;

if(angle2 > angle) {
    angle = angle2;
    delta = 3;
}

if (angle < 0) {
    angle += 360;
}

zoomfactor = Math.floor(Math.log(960 * 360 / angle / GLOBE_WIDTH) / Math.LN2) - 2 - delta;

Delta is there, because i have a bigger width than height.

"Global" JavaScript variables are members of the window object. You could access the reference as a member of the window object.

var v = "initialized";

function byref(ref) {
  window[ref] = "changed by ref";
}

byref((function(){for(r in window){if(window[r]===v){return(r);}}})());
// It could also be called like... byref('v');
console.log(v); // outputs changed by ref

Note, the above example will not work for variables declared within a function.

You need a mechanism which avoids busy-waiting. The old wait/notify mechanism is fraught with pitfalls so prefer something from the java.util.concurrent library, for example the CountDownLatch:

public final CountDownLatch latch = new CountDownLatch(1);

public void run () {
  latch.await();
  ...
}

And at the other side call

yourRunnableObj.latch.countDown();

However, starting a thread to do nothing but wait until it is needed is still not the best way to go. You could also employ an ExecutorService to which you submit as a task the work which must be done when the condition is met.

I fixed this issue as adding Dynamic Web Module to Project Facets

1. right click on project name in the Package Explorer view.
2. select Properties
3. Select Project Facets
4. Activate Dynamic Web Module
5. Click on OK

Yep, I had this exact same problem. It was because I specified the android:name attribute in the application node in the manifest file.

Your Android Manifest file probably looks something like this:

   <application 
       android:name="Novak ESC Track guide" 
       android:icon="@drawable/icon" 
       android:label="@string/app_name" 
       android:description="@string/help_text" >

Do not use the android:name attribute! unless you've implemented a custom Application object.

The application:name attribute has nothing to do with the name of your app. This is the name of a specific class to load as your Application instance. That's why you would get the ClassNotFoundException if that class wouldn't exist.

For the name of the app use the android:label attribute on this same application node instead.

Remove it and it should work:

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:description="@string/help_text" >

You can check for port numbers with these command examples on wireshark:-

tcp.port==80

tcp.port==14220

#ifdef 0
...
#endif

#ifdef expect a macro rather than expression when using constant or expression

#if 0
...
#endif

or

#if !defined(PP_CHECK) || defined(PP_CHECK_OTHER)
..
#endif

if #ifdef is used the it reports this error

#ifdef !defined(PP_CHECK) || defined(PP_CHECK_OTHER)
..
#endif

Where #ifdef expect a macro rather than macro expresssion

See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:

...
vector::iterator iterator1;

  iterator1= vec1.begin();
  vec1.insert ( iterator1+i , vec2[i] );

// This means that at position "i" from the beginning it will insert the value from vec2 from position i

Your first approach was replacing the values from vec1[i] with the values from vec2[i]

The most recent versions of hibernate JPA provider applies the bean validation constraints (JSR 303) like @NotNull to DDL by default (thanks to hibernate.validator.apply_to_ddl property defaults to true). But there is no guarantee that other JPA providers do or even have the ability to do that.

You should use bean validation annotations like @NotNull to ensure, that bean properties are set to a none-null value, when validating java beans in the JVM (this has nothing to do with database constraints, but in most situations should correspond to them).

You should additionally use the JPA annotation like @Column(nullable = false) to give the jpa provider hints to generate the right DDL for creating table columns with the database constraints you want. If you can or want to rely on a JPA provider like Hibernate, which applies the bean validation constraints to DDL by default, then you can omit them.

The following is works best in my opinion:

Get-Item Env:PATH

1. It's shorter and therefore a little bit easier to remember than Get-ChildItem. There's no hierarchy with environment variables.
2. The command is symmetrical to one of the ways that's used for setting environment variables with Powershell. (EX: Set-Item -Path env:SomeVariable -Value "Some Value")
3. If you get in the habit of doing it this way you'll remember how to list all Environment variables; simply omit the entry portion. (EX: Get-Item Env:)

I found the syntax odd at first, but things started making more sense after I understood the notion of Providers. Essentially PowerShell let's you navigate disparate components of the system in a way that's analogous to a file system.

What's the point of the trailing colon in Env:? Try listing all of the "drives" available through Providers like this:

PS> Get-PSDrive

I only see a few results... (Alias, C, Cert, D, Env, Function, HKCU, HKLM, Variable, WSMan). It becomes obvious that Env is simply another "drive" and the colon is a familiar syntax to anyone who's worked in Windows.

You can navigate the drives and pick out specific values:

Get-ChildItem C:\Windows
Get-Item C:
Get-Item Env:
Get-Item HKLM:
Get-ChildItem HKLM:SYSTEM

Here is a way to easily escape & char in oracle DB

set escape '\\'

and within query write like

'ERRORS &\\\ PERFORMANCE';

Another (much safer) approach is to escape all the characters (and not just a few special ones that we currently know) using the unicode escape format \u{code}:

function escapeRegExp(text) {
    return Array.from(text)
           .map(char => `\\u{${char.charCodeAt(0).toString(16)}}`)
           .join('');
}

console.log(escapeRegExp('a.b')); // '\u{61}\u{2e}\u{62}'

Please note that you need to pass the u flag for this method to work:

var expression = new RegExp(escapeRegExp(usersString), 'u');

A simple example would be an app that collects input data from the user and then uses Ajax to upload said data to a database. Here's a simplified example (haven't run it - may have syntax errors):

export default class Task extends React.Component {
  
  constructor(props, context) {
    super(props, context);
    this.state = {
      name: "",
      age: "",
      country: ""
    };
  }

  componentDidUpdate() {
    this._commitAutoSave();
  }

  _changeName = (e) => {
    this.setState({name: e.target.value});
  }

  _changeAge = (e) => {
    this.setState({age: e.target.value});
  }

  _changeCountry = (e) => {
    this.setState({country: e.target.value});
  }

  _commitAutoSave = () => {
    Ajax.postJSON('/someAPI/json/autosave', {
      name: this.state.name,
      age: this.state.age,
      country: this.state.country
    });
  }

  render() {
    let {name, age, country} = this.state;
    return (
      <form>
        <input type="text" value={name} onChange={this._changeName} />
        <input type="text" value={age} onChange={this._changeAge} />
        <input type="text" value={country} onChange={this._changeCountry} />
      </form>
    );
  }
}

So whenever the component has a state change it will autosave the data. There are other ways to implement it too. The componentDidUpdate is particularly useful when an operation needs to happen after the DOM is updated and the update queue is emptied. It's probably most useful on complex renders and state or DOM changes or when you need something to be the absolutely last thing to be executed.

The example above is rather simple though, but probably proves the point. An improvement could be to limit the amount of times the autosave can execute (e.g max every 10 seconds) because right now it will run on every key-stroke.

I made a demo on this fiddle as well to demonstrate.

For more info, refer to the official docs:

componentDidUpdate() is invoked immediately after updating occurs. This method is not called for the initial render.

Use this as an opportunity to operate on the DOM when the component has been updated. This is also a good place to do network requests as long as you compare the current props to previous props (e.g. a network request may not be necessary if the props have not changed).

In response to @A.M.K's question about how to do transitions without jQuery. A very simple example I threw together. If I had time to think this through some more, I might be able to eliminate the JavaScript code altogether:

<style>
    body {
        background-color: red;
        transition: background-color 2s ease-in;
    }
</style>

<script>
    window.onload = function() {
        document.body.style.backgroundColor = '#00f';
    }
</script>

<body>
    <p>test</p>
</body>

Easiest solution

<button type="button" onclick="window.location.href='{{ url_for( 'move_forward') }}';">Forward</button>

$(".ui-widget-overlay").click (function () {
    $("#dialog-id").dialog( "close" );
});

Fiddle showing the above code in action.

Filezilla is great and it can support command line arguments.

You can use stack from the base package. But, you need first to coerce your matrix to a data.frame and to reorder the columns once the data is stacked.

mat <- as.data.frame(mat)
res <- data.frame(time= mat$time,stack(mat,select=-time))
res[,c(3,1,2)]

  ind time values
1 C_0  0.0    0.1
2 C_0  0.5    0.2
3 C_0  1.0    0.3
4 C_1  0.0    0.3
5 C_1  0.5    0.4
6 C_1  1.0    0.5

Note that stack is generally more efficient than the reshape2 package.

Just my two cents : the best way (but probably not the quickest in the short term) would probably be for each developer to work on his own database instance (see rule #1 for database work).

Installing Oracle on a developer station has become a no brainer since Oracle Database 10g Express Edition.

There are many plugins for doing that. I normally use datatables it works great. http://datatables.net/

Although it is an old topic, but i wonder why there is none mentioning a very simple api of python called rpartition in this case:

to get extension of a given file absolute path, you can simply type:

filepath.rpartition('.')[-1]

example:

path = '/home/jersey/remote/data/test.csv'
print path.rpartition('.')[-1]

will give you: 'csv'

This should help you

git init
git add .
git commit -m 'Initial Commit'
git push -u origin master

As @Nils mentionned, you can use the update_fields keyword argument of the save() method to manually specify the fields to update.

obj_instance = Model.objects.get(field=value)
obj_instance.field = new_value
obj_instance.field2 = new_value2

obj_instance.save(update_fields=['field', 'field2'])

The update_fields value should be a list of the fields to update as strings.

See https://docs.djangoproject.com/en/2.1/ref/models/instances/#specifying-which-fields-to-save

I had the same question for macOS.

But the root cause was not installing Six. My macOS shipped Python version 2.7 was being usurped by a Python2 version I inherited by installing a package via brew.

I fixed my issue with: $ brew uninstall python@2

Some context on here: https://bugs.swift.org/browse/SR-1061

Simple to do it in XAML, and surprised that nobody posted this answer yet. In the following example, the Window is defined in a ResourceLibrary (notice the x:Key), but you can also use this XAML binding on a standalone Page-style WPF resource.

<Window x:Key="other_window" 
        Topmost="{Binding Source={x:Static Application.Current},Path=MainWindow.IsActive,Mode=OneWay}">
    <TextBlock Text="OTHER WINDOW" />
</Window>

You can use substring function:

s.substring(0,s.length() - 2));

With the first 0, you say to substring that it has to start in the first character of your string and with the s.length() - 2 that it has to finish 2 characters before the String ends.

For more information about substring function you can see here:

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

The problem happens whenever a process uses port 80.

You can run Netstat which is available in XAMPP Control Panel and check which process uses port 80 in your system.

For me it wasn't IIS, but Skype.

Turn off that process/application and then start the Apache services.

If you have a toggle switch that toggles between list to grid, don't forget to call recyclerView.removeItemDecoration() before setting any new Item decoration. If not then the new calculations for the spacing would be incorrect.

Something like this.

        recyclerView.removeItemDecoration(gridItemDecorator)
        recyclerView.removeItemDecoration(listItemDecorator)
        if (showAsList){
            recyclerView.layoutManager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
            recyclerView.addItemDecoration(listItemDecorator)
        }
        else{
            recyclerView.layoutManager = GridLayoutManager(this, spanCount)
            recyclerView.addItemDecoration(gridItemDecorator)
        }

To be pedantic, it's probably not good to hardcode either / or \ as the path separator. Maybe this would be best?

mypath = os.path.join('c:%s' % os.sep, 'sourcedir')

or

mypath = os.path.join('c:' + os.sep, 'sourcedir')

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Basically if you want to set size and make it change then set it to state on layout like this:

import React, { Component } from 'react';
import { AppRegistry, StyleSheet, View } from 'react-native';

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'yellow',
  },
  View1: {
    flex: 2,
    margin: 10,
    backgroundColor: 'red',
    elevation: 1,
  },
  View2: {
    position: 'absolute',
    backgroundColor: 'orange',
    zIndex: 3,
    elevation: 3,
  },
  View3: {
    flex: 3,
    backgroundColor: 'green',
    elevation: 2,
  },
  Text: {
    fontSize: 25,
    margin: 20,
    color: 'white',
  },
});

class Example extends Component {

  constructor(props) {
    super(props);

    this.state = {
      view2LayoutProps: {
        left: 0,
        top: 0,
        width: 50,
        height: 50,
      }
    };
  }

  onLayout(event) {
    const {x, y, height, width} = event.nativeEvent.layout;
    const newHeight = this.state.view2LayoutProps.height + 1;
    const newLayout = {
        height: newHeight ,
        width: width,
        left: x,
        top: y,
      };

    this.setState({ view2LayoutProps: newLayout });
  }

  render() {
    return (
      <View style={styles.container}>
        <View style={styles.View1}>
          <Text>{this.state.view2LayoutProps.height}</Text>
        </View>
        <View onLayout={(event) => this.onLayout(event)} 
              style={[styles.View2, this.state.view2LayoutProps]} />
        <View style={styles.View3} />
      </View>
    );
  }

}


AppRegistry.registerComponent(Example);

You can create many more variation of how it should be modified, by using this in another component which has Another view as wrapper and create an onResponderRelease callback, which could pass the touch event location into the state, which could be then passed to child component as property, which could override onLayout updated state, by placing {[styles.View2, this.state.view2LayoutProps, this.props.touchEventTopLeft]} and so on.

Simplest Solution

Step 1: Use the latest support library

compile 'com.android.support:appcompat-v7:25.2.0'

Step 2: Use AppCompatActivity as your parent Activity class

public class MainActivity extends AppCompatActivity

Step 3: Use app namespace in your layout XML file

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

Step 4: Use AppCompatButton instead of Button

<android.support.v7.widget.AppCompatButton
    android:id="@+id/buttonAwesome"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Awesome Button"
    android:textColor="@color/whatever_text_color_you_want"
    app:backgroundTint="@color/whatever_background_color_you_want"/>

I scripted this for my Dropbox file list.

sed is used for removing full paths of symlinked file/folder path coming after ->

Unfortunately, tabs are lost. Using zsh I am able to preserve tabs.

!/usr/bin/env bash

#!/usr/bin/env zsh

F1='index-2.md' #With hyperlinks
F2='index.md'

if [ -e $F1 ];then
    rm $F1
fi

if [ -e $F2 ];then
    rm $F2
fi

DATA=`tree --dirsfirst -t -Rl --noreport | \
    sed 's/->.*$//g'`             # Remove symlink adress and ->

echo -e '```\n' ${DATA} '\n```' > $F1  # Markdown needs triple back ticks for <pre>

# With the power of piping, creating HTML tree than pipe it
# to html2markdown program, creates cool markdown file with hyperlinks.

DATA=`tree --dirsfirst -t -Rl --noreport -H http://guneysu.pancakeapps.com`
echo $DATA | \
    sed 's/\r\r/\n/g' | \
    html2markdown | \
    sed '/^\s*$/d' | \
    sed 's/\# Directory Tree//g' | \
        > $F2

The outputs like this:

input(prompt) is basically equivalent to

def input(prompt):
    print(prompt, end='', file=sys.stderr)
    return sys.stdin.readline()

You can read directly from sys.stdin if you like.

lines = sys.stdin.readlines()

lines = [line for line in sys.stdin]

five_lines = list(itertools.islice(sys.stdin, 5))

The first two require that the input end somehow, either by reaching the end of a file or by the user typing Control-D (or Control-Z in Windows) to signal the end. The last one will return after five lines have been read, whether from a file or from the terminal/keyboard.

In maven, folder resources, create the same package structure where the configuration files are located and copy them there

Use directive to restrict the user to enter only numbers in the following way:

.directive('onlyNumber', function () {
    var regExp = /^[0-9]*$/;
    return {
        require: '?ngModel',
        restrict: 'A',
        priority: 1,
        link: function (scope, elm, attrs, ctrl) {
            ctrl.$validators.onlyNumber= function (modalValue) {
                return ctrl.$isEmpty(modalValue) || regExp.test(modalValue);
            };
        }
    };
    })

In HTML:

<input id="txtRollNumber" type="text" name="rollNumber" placeholder="Enter roll number*" ng-model="rollNumber" class="form-control" maxlength="100" required only-number />

Angular2:

    import { Directive, ElementRef, HostListener, Input } from '@angular/core';

@Directive({
  selector: '[OnlyNumber]'
})
export class OnlyNumber {

  constructor(private el: ElementRef) { }

  @Input() OnlyNumber: boolean;

  @HostListener('keydown', ['$event']) onKeyDown(event) {
    let e = <KeyboardEvent> event;
    if (this.OnlyNumber) {
      if ([46, 8, 9, 27, 13, 110, 190].indexOf(e.keyCode) !== -1 ||
        // Allow: Ctrl+A
        (e.keyCode === 65 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+C
        (e.keyCode === 67 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+V
        (e.keyCode === 86 && (e.ctrlKey || e.metaKey)) ||
        // Allow: Ctrl+X
        (e.keyCode === 88 && (e.ctrlKey || e.metaKey)) ||
        // Allow: home, end, left, right
        (e.keyCode >= 35 && e.keyCode <= 39)) {
          // let it happen, don't do anything
          return;
        }
        // Ensure that it is a number and stop the keypress
        if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
            e.preventDefault();
        }
      }
  }
}

And need to write the directive name in your input as an attribute.

<input OnlyNumber="true" />

Place your pointer on the dock button and long click it (some seconds) or right & left mouse click depending on the browser version.

Use dispatch groups: see here for an example, "Waiting on Groups of Queued Tasks" in the "Dispatch Queues" chapter of Apple's iOS Developer Library's Concurrency Programming Guide

Your example could look something like this:

dispatch_group_t group = dispatch_group_create();

dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block1
    NSLog(@"Block1");
    [NSThread sleepForTimeInterval:5.0];
    NSLog(@"Block1 End");
});


dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block2
    NSLog(@"Block2");
    [NSThread sleepForTimeInterval:8.0];
    NSLog(@"Block2 End");
});

dispatch_group_notify(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block3
    NSLog(@"Block3");
});

// only for non-ARC projects, handled automatically in ARC-enabled projects.
dispatch_release(group);

and could produce output like this:

2012-08-11 16:10:18.049 Dispatch[11858:1e03] Block1
2012-08-11 16:10:18.052 Dispatch[11858:1d03] Block2
2012-08-11 16:10:23.051 Dispatch[11858:1e03] Block1 End

Edit: This answer is wrong, even though, strictly speaking, the code works. I'm only leaving it here because the discussion under it is too useful. This other answer is the best answer given at the time I last edited this: How do I pass a unique_ptr argument to a constructor or a function?

The basic idea of ::std::move is that people who are passing you the unique_ptr should be using it to express the knowledge that they know the unique_ptr they're passing in will lose ownership.

This means you should be using an rvalue reference to a unique_ptr in your methods, not a unique_ptr itself. This won't work anyway because passing in a plain old unique_ptr would require making a copy, and that's explicitly forbidden in the interface for unique_ptr. Interestingly enough, using a named rvalue reference turns it back into an lvalue again, so you need to use ::std::move inside your methods as well.

This means your two methods should look like this:

Base(Base::UPtr &&n) : next(::std::move(n)) {} // Spaces for readability

void setNext(Base::UPtr &&n) { next = ::std::move(n); }

Then people using the methods would do this:

Base::UPtr objptr{ new Base; }
Base::UPtr objptr2{ new Base; }
Base fred(::std::move(objptr)); // objptr now loses ownership
fred.setNext(::std::move(objptr2)); // objptr2 now loses ownership

As you see, the ::std::move expresses that the pointer is going to lose ownership at the point where it's most relevant and helpful to know. If this happened invisibly, it would be very confusing for people using your class to have objptr suddenly lose ownership for no readily apparent reason.

I recorded a macro with 'Relative References' and this is what I got :

Range("F10").Select
ActiveCell.Offset(0, 3).Range("A1:D11").Select

Heres what I thought : If the range selection is in quotes, VBA really wants a STRING and interprets the cells out of it so tried the following:

Dim MyRange as String
MyRange = "A1:D11"
Range(MyRange).Select

And it worked :) ie.. just create a string using your variables, make sure to dimension it as a STRING variables and Excel will read right off of it ;)

Following tested and found working :

Sub Macro04()

Dim Copyrange As String

Startrow = 1
Lastrow = 11
Let Copyrange = "A" & Startrow & ":" & "D" & Lastrow
Range(Copyrange).Select
End Sub

Heap pollution is a technical term. It refers to references which have a type that is not a supertype of the object they point to.

List<A> listOfAs = new ArrayList<>();
List<B> listOfBs = (List<B>)(Object)listOfAs; // points to a list of As

This can lead to "unexplainable" ClassCastExceptions.

// if the heap never gets polluted, this should never throw a CCE
B b = listOfBs.get(0); 

@SafeVarargs does not prevent this at all. However, there are methods which provably will not pollute the heap, the compiler just can't prove it. Previously, callers of such APIs would get annoying warnings that were completely pointless but had to be suppressed at every call site. Now the API author can suppress it once at the declaration site.

However, if the method actually is not safe, users will no longer be warned.

I would say that it's preferable to use as few special characters as possible in REST URLs. One of the benefits of REST is that it makes the "interface" for a service easy to read. Camel case or Pascal case is probably good for the resource names (Users or users). I don't think there are really any hard standards around REST.

Also, I think Gandalf is right, it's usually cleaner in REST to not use query string parameters, but instead create paths that define which resources you want to deal with.

Edit /var/lib/logrotate.status (or /var/lib/loglogrotate/logrotate.status) to reset the 'last rotated' date on the log file you want to test.

Then run logrotate YOUR_CONFIG_FILE.

Or you can use the --force flag, but editing logrotate.status gives you more precision over what does and doesn't get rotated.

Press Control + H, then select Options and check Match entire cell contents and Match case. In the Find what field type a 0, and leave the Replace with field blank. Then Replace All. This will remove all of the zeros that are stand alone.

Try using dynamic SQL:

create procedure sp_First @columnname varchar 
AS 
begin 
    declare @sql nvarchar(4000);
    set @sql='select ['+@columnname+'] from Table_1';
    exec sp_executesql @sql
end 
go

exec sp_First 'sname'
go

You forgot to mention the name of your database (is it "my"?).

ALTER DATABASE my SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

ALTER DATABASE my SET OFFLINE;

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Data,
   Filename = 'D:\DATA\my.MDF'
);

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Log, 
   Filename = 'D:\DATA\my_1.LDF'
);

Now here you must manually move the files from their current location to D:\Data\ (and remember to rename them manually if you changed them in the MODIFY FILE command) ... then you can bring the database back online:

ALTER DATABASE my SET ONLINE;

ALTER DATABASE my SET MULTI_USER;

This assumes that the SQL Server service account has sufficient privileges on the D:\Data\ folder. If not you will receive errors at the SET ONLINE command.

Consistency is what everyone strongly suggest, the rest is upto you as long as it works.

For beginners its easy to get carried away and we name whatever we want at that time. This make sense at that point but a headache later.

foo foobar or foo_bar is great. We name our table straight forward as much as possible and only use underscore if they are two different words. studentregistration to student_registration

like @Zbyszek says, having a simple id is more than enough for the auto-increment. The simplier the better. Why do you need foo_id? We had the same problem early on, we named all our columns with the table prefix. like foo_id, foo_name, foo_age. We dropped the tablename now and kept only the col as short as possible.

Since we are using just an id for PK we will be using foo_bar_fk (tablename is unique, folowed by the unique PK, followed by the _fk) as foreign key. We don't add id to the col name because it is said that the name 'id' is always the PK of the given table. So we have just the tablename and the _fk at the end.

For constrains we remove all underscores and join with camelCase (tablename + Colname + Fk) foobarUsernameFk (for username_fk col). It's just a way we are following. We keep a documentation for every names structures.

When keeping the col name short, we should also keep an eye on the RESTRICTED names.

+------------------------------------+
|               foobar               |
+------------------------------------+
| id (PK for the current table)      |
| username_fk (PK of username table) |
| location (other column)            |
| tel (other column)                 |
+------------------------------------+

Thank you all for your contribution! I found the problem:

ITS A FIREBUG BUG !!!

My code works. I have asked the PHP Dev to change the input types hidden in to input type text. The disabled feature works. But the firebug console does not update this status!

you can test out this firebug bug by your self here http://jsbin.com/uneti3/3#. Thx to aSeptik for the example page.

update: 2. June 2012: Firebug in FF11 still has this bug.

String dateStart = "01/14/2015 08:29:58";
String dateStop = "01/15/2015 11:31:48";

//HH converts hour in 24 hours format (0-23), day calculation
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");

Date d1 = null;
Date d2 = null;

d1 = format.parse(dateStart);
d2 = format.parse(dateStop);

//in milliseconds
long diff = d2.getTime() - d1.getTime();

long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);

System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");

The main difference is that if you use a synchronized block you may lock on an object other than this which allows to be much more flexible.

Assume you have a message queue and multiple message producers and consumers. We don't want producers to interfere with each other, but the consumers should be able to retrieve messages without having to wait for the producers. So we just create an object

Object writeLock = new Object();

And from now on every time a producers wants to add a new message we just lock on that:

synchronized(writeLock){
  // do something
}

So consumers may still read, and producers will be locked.

There's a bit of confusion in your question:

• a Date datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE into a Date.
• When you want to display a date, either on screen or to send it to another system via a character API (XML, file...), you use the TO_CHAR function. In Oracle, a Date has no format: it is a point in time.
• Reciprocally, you would use TO_TIMESTAMP_TZ to convert a VARCHAR2 to a TIMESTAMP, but this won't convert a Date to a TIMESTAMP.
• You use FROM_TZ to add the time zone information to a TIMESTAMP (or a Date).
• In Oracle, CST is a time zone but CDT is not. CDT is a daylight saving information.
• To complicate things further, CST/CDT (-05:00) and CST/CST (-06:00) will have different values obviously, but the time zone CST will inherit the daylight saving information depending upon the date by default.

So your conversion may not be as simple as it looks.

Assuming that you want to convert a Date d that you know is valid at time zone CST/CST to the equivalent at time zone CST/CDT, you would use:

SQL> SELECT from_tz(d, '-06:00') initial_ts,
  2         from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
  3    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  4                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  5            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00

My default timestamp format has been used here. I can specify a format explicitely:

SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
  2         to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
  3                 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
  4    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  5                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  6            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
2012-10-09 01:10:21 -06:00      2012-10-09 02:10:21 -05:00

The data-toggle attribute simple tell Bootstrap what exactly to do by giving it the name of the toggle action it is about to perform on a target element. If you specify collapse. It means bootstrap will collapse or uncollapse the element pointed by data-target of the action you clicked

Note: the target element must have the appropriate class for bootstrap to carry out the action

Source action:
data-toggle = collapse //type of toggle
data-target = #myDiv

Target:
class=collapse //I can collapse
id=myDiv

This is same for other type of toggle actions like tab, modal, dropdown

function EmailValidation($email)
{
    $email = htmlspecialchars(stripslashes(strip_tags($email))); //parse unnecessary characters to prevent exploits
    if (eregi('[a-z||0-9]@[a-z||0-9].[a-z]', $email)) {
        //checks to make sure the email address is in a valid format
        $domain = explode( "@", $email ); //get the domain name
        if (@fsockopen ($domain[1],80,$errno,$errstr,3)) {
            //if the connection can be established, the email address is probably valid
            echo "Domain Name is valid ";
            return true;
        } else {
            echo "Con not a email domian";
            return false; //if a connection cannot be established return false
        }
        return false; //if email address is an invalid format return false
    }
}

I'd stick to ActionChains for this.

Here's a function which opens a new tab and switches to that tab:

import time
from selenium.webdriver.common.action_chains import ActionChains

def open_in_new_tab(driver, element, switch_to_new_tab=True):
    base_handle = driver.current_window_handle
    # Do some actions
    ActionChains(driver) \
        .move_to_element(element) \
        .key_down(Keys.COMMAND) \
        .click() \
        .key_up(Keys.COMMAND) \
        .perform()
    
    # Should you switch to the new tab?
    if switch_to_new_tab:
        new_handle = [x for x in driver.window_handles if x!=base_handle]
        assert len new_handle == 1 # assume you are only opening one tab at a time
        
        # Switch to the new window
        driver.switch_to.window(new_handle[0])

        # I like to wait after switching to a new tab for the content to load
        # Do that either with time.sleep() or with WebDriverWait until a basic
        # element of the page appears (such as "body") -- reference for this is 
        # provided below
        time.sleep(0.5)        

        # NOTE: if you choose to switch to the window/tab, be sure to close
        # the newly opened window/tab after using it and that you switch back
        # to the original "base_handle" --> otherwise, you'll experience many
        # errors and a painful debugging experience...

Here's how you would apply that function:

# Remember your starting handle
base_handle = driver.current_window_handle

# Say we have a list of elements and each is a link:
links = driver.find_elements_by_css_selector('a[href]')

# Loop through the links and open each one in a new tab
for link in links:
    open_in_new_tab(driver, link, True)
    
    # Do something on this new page
    print(driver.current_url)
    
    # Once you're finished, close this tab and switch back to the original one
    driver.close()
    driver.switch_to.window(base_handle)
    
    # You're ready to continue to the next item in your loop

Here's how you could wait until the page is loaded.

Try this

$(element).css({
    "propertyName1":"propertyValue1",
    "propertyName2":"propertyValue2"
})

Maybe:

crimefile = open(fileName, 'r')
yourResult = [line.split(',') for line in crimefile.readlines()]

I found an answer that I like much better here

Looks like this:

$(document).ready(function(){
    $("a").click(function () { 
        $(this).fadeTo("fast", .5).removeAttr("href"); 
    });
});

Enabling would involve setting the href attribute

$(document).ready(function(){
    $("a").click(function () { 
        $(this).fadeIn("fast").attr("href", "http://whatever.com/wherever.html"); 
    });
});

This gives you the appearance that the anchor element becomes normal text, and vice versa.

In addition to protonpack, jOO?'s Seq provides this functionality (and by extension libraries that build on it like cyclops-react, I am the author of this library).

Seq.seq(Stream.of(names)).zipWithIndex()
                         .filter( namesWithIndex -> namesWithIndex.v1.length() <= namesWithIndex.v2 + 1)
                         .toList();

Seq also supports just Seq.of(names) and will build a JDK Stream under the covers.

The simple-react equivalent would similarly look like

 LazyFutureStream.of(names)
                 .zipWithIndex()
                 .filter( namesWithIndex -> namesWithIndex.v1.length() <= namesWithIndex.v2 + 1)
                 .toList();

The simple-react version is more tailored for asynchronous / concurrent processing.

An easier way to do this in the current stable version (1.0.6) requires a lot less code.

After setting up your module add a factory:

var app = angular.module('myApp', []);
// Configure routes and controllers and views associated with them.
app.config(function ($routeProvider) {
    // route setups
});
app.factory('MyCache', function ($cacheFactory) {
    return $cacheFactory('myCache');
});

Now you can pass this into your controller:

app.controller('MyController', function ($scope, $http, MyCache) {
    $http.get('fileInThisCase.json', { cache: MyCache }).success(function (data) {
        // stuff with results
    });
});

One downside is that the key names are also setup automatically, which could make clearing them tricky. Hopefully they'll add in some way to get key names.

check the /tmp/tmp/server.pid

there is a pid inside.

Usually, I ill do "kill -9 THE_PID" in the cmd

Personaly I think it's not the problem caused by type casting but a buffer overflow problem; it is this line

cvCopy(iplimagearray[i], xyz);   

that I think will cause segment fault, I suggest that you confirm the array iplimagearray[i] have enough size of buffer to receive copyed data

You can specialize your templates based on what's passed into their parameters like this:

template <> void foo<animal> {

}

Note that this creates an entirely new function based on the type that's passed as T. This is usually preferable as it reduces clutter and is essentially the reason we have templates in the first place.

Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.

If this is the case, you'll want to use an UPDATE...FROM statement:

UPDATE MyTable
SET
    complete = 1,
    complete_date = newdata.complete_date,
    post_score = newdata.post_score
FROM
    (
    SELECT
        userID,
        complete_date,
        post_score
    FROM MyTable
    WHERE
        courseID = 6
        AND complete = 1
        AND complete_date > '8/1/2008'
    ) newdata
WHERE
    CourseID = 11
    AND userID = newdata.userID

nc one-liner local test server

Setup a local test server in one line under Linux:

nc -kdl localhost 8000

Sample request maker on another shell:

nc from the netcat-openbsd package is widely available and pre-installed on Ubuntu.

Tested on Ubuntu 18.04.

I think the confusion is that on my server I had to right click the Task Scheduler Library on left hand side and right click to get the option to enable or disable all tasks history.

With the following code:

$flag = true;
foreach($find_letters as $letter)
    if(false===strpos($string, $letter)) {
        $flag = false; 
        break;
    }

Then check the value of $flag. If it is true, all letters have been found. If not, it's false.

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']

You might find the yes command useful.

See man yes

testSpace.Style.Add("display", "none");

In my case, the setting was HKEY_CURRENT_USER\Software\Policies\Google\Chrome

I deleted Chrome and everything is fine now.

columnDefinition will override the sql DDL generated by hibernate for this particular column, it is non portable and depends on what database you are using. You can use it to specify nullable, length, precision, scale... ect.

If you don't mind getting a new data frame object returned as opposed to updating the original Pandas .assign() will avoid SettingWithCopyWarning. Your example:

df = df.assign(B=df1['E'])

You can use Notification and NotificationManager to display the notification you want. You can then customize the sound you want to play with your notification.

For anyone getting this exception while reading data from the stream, this may help. I was getting this exception when reading the HttpResponseMessage in a loop like this:

using (var remoteStream = await response.Content.ReadAsStreamAsync())
using (var content = File.Create(DownloadPath))
{
    var buffer = new byte[1024];
    int read;

    while ((read = await remoteStream.ReadAsync(buffer, 0, buffer.Length)) != 0)
    {
        await content.WriteAsync(buffer, 0, read);
        await content.FlushAsync();
    }
}

After some time I found out the culprit was the buffer size, which was too small and didn't play well with my weak Azure instance. What helped was to change the code to:

using (Stream remoteStream = await response.Content.ReadAsStreamAsync())
using (FileStream content = File.Create(DownloadPath))
{
    await remoteStream.CopyToAsync(content);
}

CopyTo() method has a default buffer size of 81920. The bigger buffer sped up the process and the errors stopped immediately, most likely because the overall download speeds increased. But why would download speed matter in preventing this error?

It is possible that you get disconnected from the server because the download speeds drop below minimum threshold the server is configured to allow. For example, in case the application you are downloading the file from is hosted on IIS, it can be a problem with http.sys configuration:

"Http.sys is the http protocol stack that IIS uses to perform http communication with clients. It has a timer called MinBytesPerSecond that is responsible for killing a connection if its transfer rate drops below some kb/sec threshold. By default, that threshold is set to 240 kb/sec."

The issue is described in this old blogpost from TFS development team and concerns IIS specifically, but may point you in a right direction. It also mentions an old bug related to this http.sys attribute: link

In case you are using Azure app services and increasing the buffer size does not eliminate the problem, try to scale up your machine as well. You will be allocated more resources including connection bandwidth.

Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns... However, there's some housekeeping to do, as you must specify the size of the target range correctly.

This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. Or at least, so much faster that it's effectively instantaneous, compared with a read or write to the worksheet, even in VBA, and you should do everything you possibly can in code before you hit the sheet.

A major component of this is error-trapping that I used to see turning up everywhere . I hate repetitive coding: I've coded it all here, and - hopefully - you'll never have to write it again.

A VBA 'Array to Range' function

Public Sub ArrayToRange(rngTarget As Excel.Range, InputArray As Variant)
' Write an array to an Excel range in a single 'hit' to the sheet
' InputArray must be a 2-Dimensional structure of the form Variant(Rows, Columns)

' The target range is resized automatically to the dimensions of the array, with
' the top left cell used as the start point.

' This subroutine saves repetitive coding for a common VBA and Excel task.

' If you think you won't need the code that works around common errors (long strings
' and objects in the array, etc) then feel free to comment them out.

You will need the source for ArrayDimensions:

This API declaration is required in the module header:

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
                   (Destination As Any, _
                    Source As Any, _
                    ByVal Length As Long)

...And here's the function itself:

Private Function ArrayDimensions(arr As Variant) As Integer
  '-----------------------------------------------------------------
  ' will return:
  ' -1 if not an array
  ' 0  if an un-dimmed array
  ' 1  or more indicating the number of dimensions of a dimmed array
  '-----------------------------------------------------------------

  Dim ptr As Long
  Dim vType As Integer

  Const VT_BYREF = &H4000&

  'get the real VarType of the argument
  'this is similar to VarType(), but returns also the VT_BYREF bit
  CopyMemory vType, arr, 2

  'exit if not an array
  If (vType And vbArray) = 0 Then
    ArrayDimensions = -1
    Exit Function
  End If

  'get the address of the SAFEARRAY descriptor
  'this is stored in the second half of the
  'Variant parameter that has received the array
  CopyMemory ptr, ByVal VarPtr(arr) + 8, 4

  'see whether the routine was passed a Variant
  'that contains an array, rather than directly an array
  'in the former case ptr already points to the SA structure.
  'Thanks to Monte Hansen for this fix

  If (vType And VT_BYREF) Then
    ' ptr is a pointer to a pointer
    CopyMemory ptr, ByVal ptr, 4
  End If

  'get the address of the SAFEARRAY structure
  'this is stored in the descriptor

  'get the first word of the SAFEARRAY structure
  'which holds the number of dimensions
  '...but first check that saAddr is non-zero, otherwise
  'this routine bombs when the array is uninitialized

  If ptr Then
    CopyMemory ArrayDimensions, ByVal ptr, 2
  End If

End Function

Also: I would advise you to keep that declaration private. If you must make it a public Sub in another module, insert the Option Private Module statement in the module header. You really don't want your users calling any function with CopyMemoryoperations and pointer arithmetic.

What you have there will return no row at all if the user doesn't exist. Here's what you need:

SELECT CASE WHEN EXISTS (
    SELECT *
    FROM [User]
    WHERE UserID = 20070022
)
THEN CAST(1 AS BIT)
ELSE CAST(0 AS BIT) END

It is better if you find quotation marks by using the indexof() method and then add a string behind that index.

string s="hai";
int s=s.indexof(""");

You can create new User library,

On

"Configure Build Paths" page -> Add Library -> User Library (on list) -> User Libraries Button (rigth side of page)

and create your library and (add Jars buttons) include your specific Jars.

I hope this can help you.

Please try this-

ALTER TABLE TABLE_NAME DROP INDEX `PRIMARY`, ADD PRIMARY KEY (COLUMN1, COLUMN2,..);

Be aware "document:keypress" is deprecated. We should use document:keydown instead.

In @dudusan's example, you could also reverse the order of I1, and then sort ascending:

> rum <- read.table(textConnection("P1  P2  P3  T1  T2  T3  I1  I2
+   2   3   5   52  43  61  6   b
+   6   4   3   72  NA  59  1   a
+   1   5   6   55  48  60  6   f
+   2   4   4   65  64  58  2   b
+   1   5   6   55  48  60  6   c"), header = TRUE)
> f=factor(rum$I1)   
> levels(f) <- sort(levels(f), decreasing = TRUE)
> rum[order(as.character(f), rum$I2), ]
  P1 P2 P3 T1 T2 T3 I1 I2
1  2  3  5 52 43 61  6  b
5  1  5  6 55 48 60  6  c
3  1  5  6 55 48 60  6  f
4  2  4  4 65 64 58  2  b
2  6  4  3 72 NA 59  1  a
> 

This seems a bit shorter, you don't reverse the order of I2 twice.

Use OLEDB Connection to communicate with excel files. it gives better result

using System.Data.OleDb;



                string physicalPath = "Your Excel file physical path";

                String connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strNewPath + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
                String query = "SELECT * FROM [Sheet1$]"; // You can use any different queries to get the data from the excel sheet
                OleDbConnection conn = new OleDbConnection(connString);
                if (conn.State == ConnectionState.Closed) conn.Open();
                try
                {
                    cmd = new OleDbCommand(query, conn);
                    da = new OleDbDataAdapter(cmd);
                    da.Fill(ds);

                }
                catch
                {
                    // Exception Msg 

                }
                finally
                {
                    da.Dispose();
                    conn.Close();
                }

The Output data will be stored in dataset, using the dataset object you can easily access the datas. Hope this may helpful

Lists of bytes are subscriptable (at least in Python 3.6). This way you can retrieve the decimal value of each byte individually.

>>> intlist = [64, 4, 26, 163, 255]
>>> bytelist = bytes(intlist)       # b'@x04\x1a\xa3\xff'

>>> for b in bytelist:
...    print(b)                     # 64  4  26  163  255

>>> [b for b in bytelist]           # [64, 4, 26, 163, 255]

>>> bytelist[2]                     # 26

For people live in 2020, and want a clean answer...

Definitions:

• delegate: defines a function pointer.
• event: defines
  • (1) protected interfaces, and
  • (2) operations(+=, -=), and
  • (3) advantage: you don't need to use new keyword anymore.

Regarding the adjective protected:

// eventTest.SomeoneSay = null;              // Compile Error.
// eventTest.SomeoneSay = new Say(SayHello); // Compile Error.

Also notice this section from Microsoft: https://docs.microsoft.com/en-us/dotnet/standard/events/#raising-multiple-events

Code Example:

with delegate:

public class DelegateTest
{
    public delegate void Say(); // Define a pointer type "void <- ()" named "Say".
    private Say say;

    public DelegateTest() {
        say  = new Say(SayHello);     // Setup the field, Say say, first.
        say += new Say(SayGoodBye);
        
        say.Invoke();
    }
    
    public void SayHello() { /* display "Hello World!" to your GUI. */ }
    public void SayGoodBye() { /* display "Good bye!" to your GUI. */ }
}

with event:

public class EventTest
{
    public delegate void Say();
    public event Say SomeoneSay;  // Use the type "Say" to define event, an 
                                  // auto-setup-everything-good field for you.
    public EventTest() {
         SomeoneSay += SayHello;
         SomeoneSay += SayGoodBye;

         SomeoneSay();
    }
    
    public void SayHello() { /* display "Hello World!" to your GUI. */ }
    public void SayGoodBye() { /* display "Good bye!" to your GUI. */ }
}

To make life easier when entering multiple dates/times it is possible to use a custom format to remove the need to enter the colon, and the leading "hour" 0. This however requires a second field for the numerical date to be stored, as the displayed date from the custom format is in base 10.

Displaying a number as a time (no need to enter colons, but no time conversion)

For displaying the times on the sheet, and for entering them without having to type the colon set the cell format to custom and use:

0/:00

Then enter your time. For example, if you wanted to enter 62:30, then you would simply type 6230 and your custom format would visually insert a colon 2 decimal points from the right.

If you only need to display the times, stop here.

Converting number to time

If you need to be able to calculate with the times, you will need to convert them from base 10 into the time format.

This can be done with the following formula (change A2 to the relevant cell reference):

=TIME(0,TRUNC(A2/100),MOD(A2,100))

• =TIME starts the number to time conversion
• We don't need hours, so enter 0, at the beginning of the formula, as the format is always hh,mm,ss (to display hours and minutes instead of minutes and seconds, place the 0 at the end of the formula).
• For the minutes, TRUNC(A2/100), discards the rightmost 2 digits.
• For the seconds, MOD(A2,100) keeps the rightmost 2 digits and discards everything to the left.

The above formula was found and adapted from this article: PC Mag.com - Easy Date and Time Entry in Excel

Alternatively, you could skip the 0/:00 custom formatting, and just enter your time in a cell to be referenced of the edge of the visible workspace or on another sheet as you would for the custom formatting (ie: 6230 for 62:30)

Then change the display format of the cells with the formula to [m]:ss as @Sean Chessire suggested.

Here is a screen shot to show what I mean.

This may be a bit controversial, but Gradle doesn't hide the fact that it's a fully-fledged programming language.

Ant + ant-contrib is essentially a turing complete programming language that no one really wants to program in.

Maven tries to take the opposite approach of trying to be completely declarative and forcing you to write and compile a plugin if you need logic. It also imposes a project model that is completely inflexible. Gradle combines the best of all these tools:

• It follows convention-over-configuration (ala Maven) but only to the extent you want it
• It lets you write flexible custom tasks like in Ant
• It provides multi-module project support that is superior to both Ant and Maven
• It has a DSL that makes the 80% things easy and the 20% things possible (unlike other build tools that make the 80% easy, 10% possible and 10% effectively impossible).

Gradle is the most configurable and flexible build tool I have yet to use. It requires some investment up front to learn the DSL and concepts like configurations but if you need a no-nonsense and completely configurable JVM build tool it's hard to beat.

The return type of a procedure is int.

You can also return result sets (as your code currently does) (okay, you can also send messages, which are strings)

Those are the only "returns" you can make. Whilst you can add table-valued parameters to a procedure (see BOL), they're input only.

Edit:

(Or as another poster mentioned, you could also use a Table Valued Function, rather than a procedure)

You can refer to the proxy documentation here.

If you need to use a proxy, you can configure individual requests with the proxies argument to any request method:

import requests

proxies = {
  "http": "http://10.10.1.10:3128",
  "https": "https://10.10.1.10:1080",
}

requests.get("http://example.org", proxies=proxies)

To use HTTP Basic Auth with your proxy, use the http://user:[email protected]/ syntax:

proxies = {
    "http": "http://user:[email protected]:3128/"
}

Peeskillet's lame tutorial for working with JTables in Netbeans GUI Builder

• Set the table column headers
  1. Highglight the table in the design view then go to properties pane on the very right. Should be a tab that says "Properties". Make sure to highlight the table and not the scroll pane surrounding it, or the next step wont work
  2. Click on the ... button to the right of the property model. A dialog should appear.
  3. Set rows to 0, set the number of columns you want, and their names.

• Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row

  1. Right-click on the button and select Events -> Action -> actionPerformed

  2. You should see code like the following auto-generated

     private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
     

• The jTable1 will have a DefaultTableModel. You can add rows to the model with your data

  private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
      String data1 = something1.getSomething();
      String data2 = something2.getSomething();
      String data3 = something3.getSomething();
      String data4 = something4.getSomething();
  
      Object[] row = { data1, data2, data3, data4 };
  
      DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
  
      model.addRow(row);
  
      // clear the entries.
  }
  

So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.
