Answering to myself. From the RequireJS website:

//THIS WILL FAIL
define(['require'], function (require) {
    var namedModule = require('name');
});

This fails because requirejs needs to be sure to load and execute all dependencies before calling the factory function above. [...] So, either do not pass in the dependency array, or if using the dependency array, list all the dependencies in it.

My solution:

// Modules configuration (modules that will be used as Jade helpers)
define(function () {
    return {
        'moment':   'path/to/moment',
        'filesize': 'path/to/filesize',
        '_':        'path/to/lodash',
        '_s':       'path/to/underscore.string'
    };
});

The loader:

define(['jade', 'lodash', 'config'], function (Jade, _, Config) {
    var deps;

    // Dynamic require
    require(_.values(Config), function () {
        deps = _.object(_.keys(Config), arguments);

        // Use deps...
    });
});

In production

urlArgs can cause problems!

The principal author of requirejs prefers not to use urlArgs:

For deployed assets, I prefer to put the version or hash for the whole build as a build directory, then just modify the baseUrl config used for the project to use that versioned directory as the baseUrl. Then no other files change, and it helps avoid some proxy issues where they may not cache an URL with a query string on it.

[Styling mine.]

I follow this advice.

In development

I prefer to use a server that intelligently caches files that may change frequently: a server that emits Last-Modified and responds to If-Modified-Since with 304 when appropriate. Even a server based on Node's express set to serve static files does this right out the box. It does not require doing anything to my browser, and does not mess up breakpoints.

I had this error because I included the requirejs file along with other librairies included directly in a script tag. Those librairies (like lodash) used a define function that was conflicting with require's define. The requirejs file was loading asynchronously so I suspect that the require's define was defined after the other libraries define, hence the conflict.

To get rid of the error, include all your other js files by using requirejs.

RequireJS implements the AMD API (source).

CommonJS is a way of defining modules with the help of an exports object, that defines the module contents. Simply put, a CommonJS implementation might work like this:

// someModule.js
exports.doSomething = function() { return "foo"; };

//otherModule.js
var someModule = require('someModule'); // in the vein of node    
exports.doSomethingElse = function() { return someModule.doSomething() + "bar"; };

Basically, CommonJS specifies that you need to have a require() function to fetch dependencies, an exports variable to export module contents and a module identifier (which describes the location of the module in question in relation to this module) that is used to require the dependencies (source). CommonJS has various implementations, including Node.js, which you mentioned.

CommonJS was not particularly designed with browsers in mind, so it doesn't fit in the browser environment very well (I really have no source for this--it just says so everywhere, including the RequireJS site.) Apparently, this has something to do with asynchronous loading, etc.

On the other hand, RequireJS implements AMD, which is designed to suit the browser environment (source). Apparently, AMD started as a spinoff of the CommonJS Transport format and evolved into its own module definition API. Hence the similarities between the two. The new feature in AMD is the define() function that allows the module to declare its dependencies before being loaded. For example, the definition could be:

define('module/id/string', ['module', 'dependency', 'array'], 
function(module, factory function) {
  return ModuleContents;  
});

So, CommonJS and AMD are JavaScript module definition APIs that have different implementations, but both come from the same origins.

• AMD is more suited for the browser, because it supports asynchronous loading of module dependencies.
• RequireJS is an implementation of AMD, while at the same time trying to keep the spirit of CommonJS (mainly in the module identifiers).

To confuse you even more, RequireJS, while being an AMD implementation, offers a CommonJS wrapper so CommonJS modules can almost directly be imported for use with RequireJS.

define(function(require, exports, module) {
  var someModule = require('someModule'); // in the vein of node    
  exports.doSomethingElse = function() { return someModule.doSomething() + "bar"; };
});

I hope this helps to clarify things!

Yes it makes sense to use requireJS with Angular, I spent several days to test several technical solutions.

I made an Angular Seed with RequireJS on Server Side. Very simple one. I use SHIM notation for no AMD module and not AMD because I think it's very difficult to deal with two different Dependency injection system.

I use grunt and r.js to concatenate js files on server depends on the SHIM configuration (dependency) file. So I refer only one js file in my app.

For more information go on my github Angular Seed : https://github.com/matohawk/angular-seed-requirejs

Gulp uses micromatch under the hood for matching globs, so if you want to exclude any of the .min.js files, you can achieve the same by using an extended globbing feature like this:

src("'js/**/!(*.min).js")

Basically what it says is: grab everything at any level inside of js that doesn't end with *.min.js

The TextBlock doesn't support vertical text alignment.

I work around this by wrapping the text block with a Grid and setting HorizontalAlignment="Stretch" and VerticalAlignment="Center".

Like this:

<Grid>
    <TextBlock 
        HorizontalAlignment="Stretch"
        VerticalAlignment="Center"
        Text="Your text" />
</Grid>

You need to identify the columns based on their position in dataframe. For example, if you want to drop (del) column number 2,3 and 5, it will be,

df.drop(df.columns[[2,3,5]], axis = 1)

You can simply use this bootstrap helper to dialogs (only 5 kB)

it has support for ajax request, iframes, common dialogs, confirm and prompt!

you can use it as:

eModal.iframe('http://someUrl.com', 'This is a tile for iframe', callbackIfNeeded);

eModal.alert('The message', 'This title');

eModal.ajax('/mypage.html', 'This is a ajax', callbackIfNeeded);

eModal.confirm('the question', 'The title', theMandatoryCallback);

eModal.prompt('Form question', 'This is a ajax', theMandatoryCallback);

this provide a loading progress while loading the iframe!

No html required.

You can use a object literal as parameter to extra options.

Check the site form more details.

For Python 3.5+ use:

import importlib.util
spec = importlib.util.spec_from_file_location("module.name", "/path/to/file.py")
foo = importlib.util.module_from_spec(spec)
spec.loader.exec_module(foo)
foo.MyClass()

For Python 3.3 and 3.4 use:

from importlib.machinery import SourceFileLoader

foo = SourceFileLoader("module.name", "/path/to/file.py").load_module()
foo.MyClass()

(Although this has been deprecated in Python 3.4.)

For Python 2 use:

import imp

foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()

There are equivalent convenience functions for compiled Python files and DLLs.

See also http://bugs.python.org/issue21436.

When the left part is an object instance, you use ->. Otherwise, you use ::.

This means that -> is mostly used to access instance members (though it can also be used to access static members, such usage is discouraged), while :: is usually used to access static members (though in a few special cases, it's used to access instance members).

In general, :: is used for scope resolution, and it may have either a class name, parent, self, or (in PHP 5.3) static to its left. parent refers to the scope of the superclass of the class where it's used; self refers to the scope of the class where it's used; static refers to the "called scope" (see late static bindings).

The rule is that a call with :: is an instance call if and only if:

• the target method is not declared as static and
• there is a compatible object context at the time of the call, meaning these must be true:
  1. the call is made from a context where $this exists and
  2. the class of $this is either the class of the method being called or a subclass of it.

Example:

class A {
    public function func_instance() {
        echo "in ", __METHOD__, "\n";
    }
    public function callDynamic() {
        echo "in ", __METHOD__, "\n";
        B::dyn();
    }

}

class B extends A {
    public static $prop_static = 'B::$prop_static value';
    public $prop_instance = 'B::$prop_instance value';

    public function func_instance() {
        echo "in ", __METHOD__, "\n";
        /* this is one exception where :: is required to access an
         * instance member.
         * The super implementation of func_instance is being
         * accessed here */
        parent::func_instance();
        A::func_instance(); //same as the statement above
    }

    public static function func_static() {
        echo "in ", __METHOD__, "\n";
    }

    public function __call($name, $arguments) {
        echo "in dynamic $name (__call)", "\n";
    }

    public static function __callStatic($name, $arguments) {
        echo "in dynamic $name (__callStatic)", "\n";
    }

}

echo 'B::$prop_static: ', B::$prop_static, "\n";
echo 'B::func_static(): ', B::func_static(), "\n";
$a = new A;
$b = new B;
echo '$b->prop_instance: ', $b->prop_instance, "\n";
//not recommended (static method called as instance method):
echo '$b->func_static(): ', $b->func_static(), "\n";

echo '$b->func_instance():', "\n", $b->func_instance(), "\n";

/* This is more tricky
 * in the first case, a static call is made because $this is an
 * instance of A, so B::dyn() is a method of an incompatible class
 */
echo '$a->dyn():', "\n", $a->callDynamic(), "\n";
/* in this case, an instance call is made because $this is an
 * instance of B (despite the fact we are in a method of A), so
 * B::dyn() is a method of a compatible class (namely, it's the
 * same class as the object's)
 */
echo '$b->dyn():', "\n", $b->callDynamic(), "\n";

Output:

B::$prop_static: B::$prop_static value
B::func_static(): in B::func_static

$b->prop_instance: B::$prop_instance value
$b->func_static(): in B::func_static

$b->func_instance():
in B::func_instance
in A::func_instance
in A::func_instance

$a->dyn():
in A::callDynamic
in dynamic dyn (__callStatic)

$b->dyn():
in A::callDynamic
in dynamic dyn (__call)

For a local copy, the only advantage of rsync is that it will avoid copying if the file already exists in the destination directory. The definition of "already exists" is (a) same file name (b) same size (c) same timestamp. (Maybe same owner/group; I am not sure...)

The "rsync algorithm" is great for incremental updates of a file over a slow network link, but it will not buy you much for a local copy, as it needs to read the existing (partial) file to run it's "diff" computation.

So if you are running this sort of command frequently, and the set of changed files is small relative to the total number of files, you should find that rsync is faster than cp. (Also rsync has a --delete option that you might find useful.)

I find the easiest way is to double up on the quotes to handle a quote.

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0,"""",Sheet1!A1)" 

Some people like to use CHR(34)*:

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0," & CHR(34) & CHR(34) & ",Sheet1!A1)" 

*Note: CHAR() is used as an Excel cell formula, e.g. writing "=CHAR(34)" in a cell, but for VBA code you use the CHR() function.

As RedBlueThing and analog said:

• dir() gives a list of in scope variables
• globals() gives a dictionary of global variables
• locals() gives a dictionary of local variables

Using the interactive shell (version 2.6.9), after creating variables a = 1 and b = 2, running dir() gives

['__builtins__', '__doc__', '__name__', '__package__', 'a', 'b']

running locals() gives

{'a': 1, 'b': 2, '__builtins__': <module '__builtin__' (built-in)>, '__package__': None, '__name__': '__main__', '__doc__': None}

Running globals() gives exactly the same answer as locals() in this case.

I haven't gotten into any modules, so all the variables are available as both local and global variables. locals() and globals() list the values of the variables as well as the names; dir() only lists the names.

If I import a module and run locals() or globals() inside the module, dir() still gives only a small number of variables; it adds __file__ to the variables listed above. locals() and globals() also list the same variables, but in the process of printing out the dictionary value for __builtin__, it lists a far larger number of variables: built-in functions, exceptions, and types such as "'type': <type 'type'>", rather than just the brief <module '__builtin__' (built-in)> as shown above.

For more about dir() see Python 2.7 quick reference at New Mexico Tech or the dir() function at ibiblio.org.

For more about locals() and globals() see locals and globals at Dive Into Python and a page about globals at New Mexico Tech.

[Comment: @Kurt: You gave a link to enumerate-or-list-all-variables-in-a-program-of-your-favorite-language-here but that answer has a mistake in it. The problem there is: type(name) in that example will always return <type 'str'>. You do get a list of the variables, which answers the question, but with incorrect types listed beside them. This was not obvious in your example because all the variables happened to be strings anyway; however, what it's returning is the type of the name of the variable instead of the type of the variable. To fix this: instead of print type(name) use print eval('type(' + name + ')'). I apologize for posting a comment in the answer section but I don't have comment posting privileges, and the other question is closed.]

Something else you could do using raytrace's answer. You could use the stdout of another shell call using backticks to then do some calculations. For instance I wanted to know the file size of the top 100 lines from a couple of files. The original size from wc -c is in bytes, I want to know kilobytes. Here's what I did:

echo `cat * | head -n 100 | wc -c` / 1024 | bc -l

You could use the append() method defined on list objects:

mergedlist =[]
for elem in listone:
    mergedlist.append(elem)
for elem in listtwo:
    mergedlist.append(elem)

A person might get this while working with factory functions, so I can confirm this is valid syntax:

$user = factory(User::class, 1)->create()->first();

You might see the collection instance error if you do something like:

$user = factory(User::class, 1)->create()->id;

so change it to:

$user = factory(User::class, 1)->create()->first()->id;

HC-way :)

This may Happen because Activity "A" may have Fragments and when you navigate to Activity "B" .

then Activity Life Cycle of activty "A" will be

Check out the PHP cURL functions. They should do what you want.

Or if you just want a simple URL GET then:

$lines = file('http://www.example.com/');

First off, please note that I haven't used either of them (but have used Node.js).

Both libraries are documented quite well and have a stable API. However, persistence.js seems to be used in more projects. I don't know if all of them still use it, though.

The developer of sequelize sometimes blogs about it at blog.depold.com. When you'd like to use primary keys as foreign keys, you'll need the patch that's described in this blog post. If you'd like help for persistence.js there is a google group devoted to it.

From the examples I gather that sequelize is a bit more JavaScript-like (more sugar) than persistance.js but has support for fewer datastores (only MySQL, while persistance.js can even use in-browser stores).

I think that sequelize might be the way to go for you, as you only need MySQL support. However, if you need some convenient features (for instance search) or want to use a different database later on you'd need to use persistence.js.

When you are not sure of the number of rows, then you can do it this way:

followers_df.index = range(len(followers_df))

The modulo operator % in C and C++ is defined for two integers, however, there is an fmod() function available for usage with doubles.

tested solution on hackerrank....

select distinct(city) from station
where substr(lower(city), length(city), 1) in ('a', 'e', 'i', 'o', 'u') and substr(lower(city), 1, 1) in ('a', 'e', 'i', 'o', 'u');

var seconds = 0;
setInterval(function () {
  seconds++;
}, 1000);

There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.

Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.

You could also solve this by saving and comparing times.

EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.

You have not joined TableD, merely selected the TableD FIELD (dID) from one of the tables.

You can replicate those brackets in the left join:

LEFT JOIN bookings  
               ON rooms.id = bookings.room_type_id
              AND (  bookings.arrival between ? and ?
                  OR bookings.departure between ? and ? )

is

->leftJoin('bookings', function($join){
    $join->on('rooms.id', '=', 'bookings.room_type_id');
    $join->on(DB::raw('(  bookings.arrival between ? and ? OR bookings.departure between ? and ? )'), DB::raw(''), DB::raw(''));
})

You'll then have to set the bindings later using "setBindings" as described in this SO post: How to bind parameters to a raw DB query in Laravel that's used on a model?

It's not pretty but it works.

You may also which to use aggregate initialization from a braced initialization list for situations like these.

#include <vector>
using namespace std;

struct subject {
    string name;
    int    marks;
    int    credits;
};

int main() {
    vector<subject> sub {
      {"english", 10, 0},
      {"math"   , 20, 5}
    };
}

Sometimes however, the members of a struct may not be so simple, so you must give the compiler a hand in deducing its types.

So extending on the above.

#include <vector>
using namespace std;

struct assessment {
    int   points;
    int   total;
    float percentage;
};

struct subject {
    string name;
    int    marks;
    int    credits;
    vector<assessment> assessments;
};

int main() {
    vector<subject> sub {
      {"english", 10, 0, {
                             assessment{1,3,0.33f},
                             assessment{2,3,0.66f},
                             assessment{3,3,1.00f}
                         }},
      {"math"   , 20, 5, {
                             assessment{2,4,0.50f}
                         }}
    };
}

Without the assessment in the braced initializer the compiler will fail when attempting to deduce the type.

The above has been compiled and tested with gcc in c++17. It should however work from c++11 and onward. In c++20 we may see the designator syntax, my hope is that it will allow for for the following

  {"english", 10, 0, .assessments{
                         {1,3,0.33f},
                         {2,3,0.66f},
                         {3,3,1.00f}
                     }},

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

I find the following link quite useful

If you get code behind, use some like this

        MyCustomObject myObject = new MyCustomObject();
        myObject.name='try';
        //OBJECT -> JSON
        var javaScriptSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        string myObjectJson = javaScriptSerializer.Serialize(myObject);
        //return JSON   
        Response.Clear();     
        Response.ContentType = "application/json; charset=utf-8";
        Response.Write(myObjectJson );
        Response.End();

So you return a json object serialized with all attributes of MyCustomObject.

The commands from WEFX worked for me after I enabled the parent features RemoteServerAdministrationTools, RemoteServerAdministrationTools-Roles, and RemoteServerAdministrationTools-Roles-AD

After a bit of time (and more searching), I found this blog entry by Jomo Fisher.

One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

[Snip]

The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>
</startup>

So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy attribute reverts back to CLR 2.0 loading.

This is what worked for me in the end.

var showMenu = function(el, menu) {
    //get the position of the placeholder element  
    var pos = $(el).offset();    
    var eWidth = $(el).outerWidth();
    var mWidth = $(menu).outerWidth();
    var left = (pos.left + eWidth - mWidth) + "px";
    var top = 3+pos.top + "px";
    //show the menu directly over the placeholder  
    $(menu).css( { 
        position: 'absolute',
        zIndex: 5000,
        left: left, 
        top: top
    } );

    $(menu).hide().fadeIn();
};

UITableViewController does the Scrolling automatically, indeed. The difference compared to using a UIViewController is, that you have to create Navbar-Buttonitems programmatically by using the NavigationController, when using a TableViewController.

if you are using XDocument.Load(url); to fetch xml from another domain, it's possible that the host will reject the request and return and unexpected (non-xml) result, which results in the above XmlException

See my solution to this eventuality here: XDocument.Load(feedUrl) returns "Data at the root level is invalid. Line 1, position 1."

list_1.insert(0,ur_data)

make sure that ur_data is of string type so if u have data= int(5) convert it to ur_data = str(data)

If there is something that is throwing off your Distinct query, you might want to look at MoreLinq and use the DistinctBy operator and select distinct objects by id.

var distinct = items.DistinctBy( i => i.Id );

No, JavaScript doesn't have access to writing files as this would be a huge security risk to say the least. If you wanted to get/store information server-side, though, you can certainly make an Ajax call to a PHP/ASP/Python/etc. script that can then get/store the data in the server. If you meant store data on the client machine, this is impossible with JavaScript alone. I suspect Flash/Java may be able to, but I am not sure.

If you are only trying to store a small amount of information for an unreliable period of time regarding a specific user, I think you want Web Storage API or cookies. I am not sure from your question what you are trying to accomplish, though.

Verify if your packageName is correct. You have to refer for the root package of your Android application.

private String getStringResourceByName(String aString) {
      String packageName = getPackageName();
      int resId = getResources().getIdentifier(aString, "string", packageName);
      return getString(resId);
    }

Jquery Datepicker defaultDate ONLY set the default date that you chose on the calendar that pops up when you click on your field. If you want the default date to APPEAR on your input before the user clicks on the field you should give a val() to your field. Something like this:

$("#searchDateFrom").datepicker({ defaultDate: "-1y -1m -6d" });
$("#searchDateFrom").val((date.getMonth()) + '/' + (date.getDate() - 6) + '/' + (date.getFullYear() - 1));

In more recent versions of NERDTree you can use the command :NERDTreeFocus, which will move focus to the NERDTree window.

The return exits the current function, but the iterations keeps on, so you get the "next" item that skips the if and alerts the 4...

If you need to stop the looping, you should just use a plain for loop like so:

$('button').click(function () {
   var arr = [1, 2, 3, 4, 5];
   for(var i = 0; i < arr.length; i++) {
     var n = arr[i]; 
     if (n == 3) {
         break;
      }
      alert(n);
   })
})

You can read more about js break & continue here: http://www.w3schools.com/js/js_break.asp

If you are able to use org.apache.commons.lang.StringUtils, I suggest using the following:

String container = "aBcDeFg";
String content = "dE";
boolean containerContainsContent = StringUtils.containsIgnoreCase(container, content);

If you have access to the application package, then you can install with the -r option and it will kill the process if it is currently running as a side effect. Like this:

adb -d install -r MyApp.apk ; adb -d shell am start -a android.intent.action.MAIN -n com.MyCompany.MyApp/.MyActivity

The -r option preserves the data currently associated with the app. However, if you want a clean slate like you mention you might not want to use that option.

Another possibility with Guava:

dependency: compile 'com.google.guava:guava:11.0.2'

import com.google.common.io.ByteStreams;
...

String total = new String(ByteStreams.toByteArray(inputStream ));

Another solution could be using jquery button selector inside the if else statement $("#buttonId").text("your text");

function showFilterItem() {
if (filterstatus == 0) {
    filterstatus = 1;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
    $("#ShowButton").text("Hide Filter");
}
else {
    filterstatus = 0;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
     $("#ShowButton").text("Show Filter");
}}

Most answers are brittle because they rely on the order of the SP's parameters. Better to name the Stored Proc's params and give parameterized values to those.

In order to use Named params when calling your SP, without worrying about the order of parameters

Using SQL Server named parameters with ExecuteStoreQuery and ExecuteStoreCommand

Describes the best approach. Better than Dan Mork's answer here.

• Doesn't rely on concatenating strings, and doesn't rely on the order of parameters defined in the SP.

E.g.:

var cmdText = "[DoStuff] @Name = @name_param, @Age = @age_param";
var sqlParams = new[]{
   new SqlParameter("name_param", "Josh"),
   new SqlParameter("age_param", 45)
};

context.Database.SqlQuery<myEntityType>(cmdText, sqlParams)

I also tried to get the field1 = 'a' OR field2 = 'b'

Your code didn't work for me.

Here is my solution

$results = Mage::getModel('xyz/abc')->getCollection();
$results->addFieldToSelect('name');
$results->addFieldToSelect('keywords');
$results->addOrder('name','ASC');
$results->setPageSize(5);

$results->getSelect()->where("keywords like '%foo%' or additional_keywords  like '%bar%'");

$results->load();

echo json_encode($results->toArray());

It gives me

SELECT name, keywords FROM abc WHERE keywords like '%foo%' OR additional_keywords like '%bar%'.

It is maybe not the "magento's way" but I was stuck 5 hours on that.

Hope it will help

Thank you all.

It's undefined; doing things like Jon Skeet suggested will get you an approximation on a given platform, but the way to know precisely for a specific platform is to use a profiler.

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in dirs:
        print os.path.join(root, name)

Walk is a good built-in for what you are doing

run

gradle clean 

then try

gradle build 

it worked for me

Similar to what Mark E has proposed, but no need to recreate the wheel, if you don't mind relying on 3rd party libs.

Apache Commons has tuples already defined:

org.apache.commons.lang3.tuple.Pair<L,R>

Apache Commons is so pervasive, I typically already have it in my projects, anyway. https://mvnrepository.com/artifact/org.apache.commons/commons-lang3

Section 6.16 Frame target names in the HTML 4.01 spec defines the meanings, but it is partly outdated. It refers to “windows”, whereas HTML5 drafts more realistically speak about “browsing contexts”, since modern browsers often use tabs instead of windows in this context.

Briefly, _self is the default (current browsing context, i.e. current window or tab), so it is useful only to override a <base target=...> setting. The value _parent refers to the frameset that is the parent of the current frame, whereas _top “breaks out of all frames” and opens the linked document in the entire browser window.

You can use the following two properties in "colors.xml"

<color name="colorControlNormal">#eeeeee</color>
<color name="colorControlActivated">#eeeeee</color>

colorControlNormal is for the normal view of checkbox, and colorControlActivated is for when the checkbox is checked.

One advantage your current approach does have is that it will raise an error if multiple rows are returned by the predicate. To reproduce that you can use.

SELECT @currentTerm = currentterm,
       @termID = termid,
       @endDate = enddate
FROM   table1
WHERE  iscurrent = 1

IF( @@ROWCOUNT <> 1 )
  BEGIN
      RAISERROR ('Unexpected number of matching rows',
                 16,
                 1)

      RETURN
  END  

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

if you need to overwrite the admin/index.html, you can set the index_template parameter of the AdminSite.

e.g.

# urls.py
...
from django.contrib import admin

admin.site.index_template = 'admin/my_custom_index.html'
admin.autodiscover()

and place your template in <appname>/templates/admin/my_custom_index.html

All the other answers are correct, but you also need to call your method correctly:

Calculate(5, 5, Operator.PLUS))

And since you use int for left and right, the result will be int as well (3/2 will result in 1). you could cast to double before calculating the result or modify your parameters to accept double

Hope it might help someone instantly.

Behavior of Division Operator in Python 2.7 and Python 3

In Python 2.7: By default, division operator will return integer output.

to get the result in double multiple 1.0 to "dividend or divisor"

100/35 => 2 #(Expected is 2.857142857142857)
(100*1.0)/35 => 2.857142857142857
100/(35*1.0) => 2.857142857142857

In Python 3

// => used for integer output
/ => used for double output

100/35 => 2.857142857142857
100//35 => 2
100.//35 => 2.0    # floating-point result if divsor or dividend real

By default, Spring beans are singletons. The problem arises when we try to wire beans of different scopes. For example, a prototype bean into a singleton. This is known as the scoped bean injection problem.

Another way to solve the problem is method injection with the @Lookup annotation.

Here is a nice article on this issue of injecting prototype beans into a singleton instance with multiple solutions.

https://www.baeldung.com/spring-inject-prototype-bean-into-singleton

echo "echo "we are now going to work with ${ser}" " >> $servfile

Escape all " within quotes with \. Do this with variables like \$servicetest too:

echo "echo \"we are now going to work with \${ser}\" " >> $servfile    
echo "read -p \"Please enter a service: \" ser " >> $servfile
echo "if [ \$servicetest > /dev/null ];then " >> $servfile

Unfortunately, there's no way to do that with CSS.

It's not very difficult with JavaScript though:

// JavaScript code:
document.getElementsByClassName("active")[0].parentNode;

// jQuery code:
$('.active').parent().get(0); // This would be the <a>'s parent <li>.

Arrays in Java aren't dynamic, like collection classes. If you want a true collection that supports dynamic addition and deletion, use ArrayList<>. If you still want to live with vanilla arrays, find the index of string, construct a new array with size one less than the original, and use System.arraycopy() to copy the elements before and after. Or write a copy loop with skip by hand, on small arrays the difference will be negligible.

I might suggest 2 things.

1) If your query takes a lot of time because it´s using several tables that might involve locks, a quite fast solution is to run your queries with the "NoLock" hint.

Simply add Select * from YourTable WITH (NOLOCK) in all your table references an that will prevent your query to block for concurrent transactions.

2) if you want to be sure that all of your queries runs in (let´s say) less than 5 seconds, then you could add what @talha proposed, that worked sweet for me

Just add at the top of your execution

SET LOCK_TIMEOUT 5000;   --5 seconds.

And that will cause that your query takes less than 5 or fail. Then you should catch the exception and rollback if needed.

Hope it helps.

CSS Solution:

.h2{
  font-size: 2vw
}
@media (min-width: 700px) {
  .h2{
    /* Minimum font size */
    font-size: 14px
  }
}
@media (max-width: 1200px) {
  .h2{
    /* Maximum font size */
    font-size: 24px
  }
}

Just in case if some need scss mixin:

///
/// Viewport sized typography with minimum and maximum values
///
/// @author Eduardo Boucas (@eduardoboucas)
///
/// @param {Number}   $responsive  - Viewport-based size
/// @param {Number}   $min         - Minimum font size (px)
/// @param {Number}   $max         - Maximum font size (px)
///                                  (optional)
/// @param {Number}   $fallback    - Fallback for viewport-
///                                  based units (optional)

/// @example scss - 5vw font size (with 50px fallback),
///                 minumum of 35px and maximum of 150px
///  @include responsive-font(5vw, 35px, 150px, 50px);
///

@mixin responsive-font($responsive, $min, $max: false, $fallback: false) {
  $responsive-unitless: $responsive / ($responsive - $responsive + 1);
  $dimension: if(unit($responsive) == 'vh', 'height', 'width');
  $min-breakpoint: $min / $responsive-unitless * 100;

  @media (max-#{$dimension}: #{$min-breakpoint}) {
    font-size: $min;
  }

  @if $max {
    $max-breakpoint: $max / $responsive-unitless * 100;

    @media (min-#{$dimension}: #{$max-breakpoint}) {
      font-size: $max;
    }
  }

  @if $fallback {
    font-size: $fallback;
  }

  font-size: $responsive;
}

Else you can get id of process your application runs in:

final static int android.os.Process.myPid()
Returns the identifier of this process, which can be used with killProcess(int) and sendSignal(int, int).

If you need to position an element relative to its containing element first you need to add position: relative to the container element. The child element you want to position relatively to the parent has to have position: absolute. The way that absolute positioning works is that it is done relative to the first relatively (or absolutely) positioned parent element. In case there is no relatively positioned parent, the element will be positioned relative to the root element (directly to the HTML element).

So if you want to position your child element to the top left of the parent container, you should do this:

.parent {
  position: relative;
} 

.child {
  position: absolute;
  top: 0;
  left: 0;  
}

You will benefit greatly from reading this article. Hope this helps!

If the bytes use an appropriate character encoding already; you could print them directly:

sys.stdout.buffer.write(data)

or

nwritten = os.write(sys.stdout.fileno(), data)  # NOTE: it may write less than len(data) bytes

From char and varchar (Transact-SQL)

varchar [ ( n | max ) ]

Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.

In cases where the Oracle solution seems overly convoluted, I create a java class with static methods and then install it as a package in Oracle. This might not be as performant, but you will eventually find other cases (date conversion to milliseconds for example) where you will find the java fallback helpful.

I would do it in the following way:

(If working with MSVC, ignore the GCC compilation commands)

Suppose that I have a C++ class named AAA, defined in files aaa.h, aaa.cpp, and that the class AAA has a method named sayHi(const char *name), that I want to enable for C code.

The C++ code of class AAA - Pure C++, I don't modify it:

aaa.h

#ifndef AAA_H
#define AAA_H

class AAA {
    public:
        AAA();
        void sayHi(const char *name);
};

#endif

aaa.cpp

#include <iostream>

#include "aaa.h"

AAA::AAA() {
}

void AAA::sayHi(const char *name) {
    std::cout << "Hi " << name << std::endl;
}

Compiling this class as regularly done for C++. This code "does not know" that it is going to be used by C code. Using the command:

g++ -fpic -shared aaa.cpp -o libaaa.so

Now, also in C++, creating a C connector. Defining it in files aaa_c_connector.h, aaa_c_connector.cpp. This connector is going to define a C function, named AAA_sayHi(cosnt char *name), that will use an instance of AAA and will call its method:

aaa_c_connector.h

#ifndef AAA_C_CONNECTOR_H 
#define AAA_C_CONNECTOR_H 

#ifdef __cplusplus
extern "C" {
#endif

void AAA_sayHi(const char *name);

#ifdef __cplusplus
}
#endif


#endif

aaa_c_connector.cpp

#include <cstdlib>

#include "aaa_c_connector.h"
#include "aaa.h"

#ifdef __cplusplus
extern "C" {
#endif

// Inside this "extern C" block, I can implement functions in C++, which will externally 
//   appear as C functions (which means that the function IDs will be their names, unlike
//   the regular C++ behavior, which allows defining multiple functions with the same name
//   (overloading) and hence uses function signature hashing to enforce unique IDs),


static AAA *AAA_instance = NULL;

void lazyAAA() {
    if (AAA_instance == NULL) {
        AAA_instance = new AAA();
    }
}

void AAA_sayHi(const char *name) {
    lazyAAA();
    AAA_instance->sayHi(name);
}

#ifdef __cplusplus
}
#endif

Compiling it, again, using a regular C++ compilation command:

g++ -fpic -shared aaa_c_connector.cpp -L. -laaa -o libaaa_c_connector.so

Now I have a shared library (libaaa_c_connector.so), that implements the C function AAA_sayHi(const char *name). I can now create a C main file and compile it all together:

main.c

#include "aaa_c_connector.h"

int main() {
    AAA_sayHi("David");
    AAA_sayHi("James");

    return 0;
}

Compiling it using a C compilation command:

gcc main.c -L. -laaa_c_connector -o c_aaa

I will need to set LD_LIBRARY_PATH to contain $PWD, and if I run the executable ./c_aaa, I will get the output I expect:

Hi David
Hi James

EDIT:

On some linux distributions, -laaa and -lstdc++ may also be required for the last compilation command. Thanks to @AlaaM. for the attention

You can use define window.myvar = {}. When you want to use it, you can use like window.myvar = 1

You can unite this

x = 0
y = 1
z = 3

in one variable.

In [1]: xyz = (0,1,3,) 
In [2]: mylist = []

Change our conditions as:

In [3]: if 0 in xyz: 
    ...:     mylist.append("c") 
    ...: if 1 in xyz: 
    ...:     mylist.append("d") 
    ...: if 2 in xyz: 
    ...:     mylist.append("e") 
    ...: if 3 in xyz:  
    ...:     mylist.append("f") 

Output:

In [21]: mylist                                                                                
Out[21]: ['c', 'd', 'f']

I'm using this alias for checking out a branch in a temporary directory:

[alias]
    cot = "!TEMP=$(mktemp -d); f() { git worktree prune && git worktree add $TEMP $1 && zsh -c \"cd $TEMP; zsh\";}; f" # checkout branch in temporary directory

Usage:

git cot mybranch

You are then dropped in a new shell in the temporary directory where you can work on the branch. You can even use git commands in this directory.

When you're done, delete the directory and run:

git worktree prune

This is also done automatically in the alias, before adding a new worktree.

Another way is casting a string to a WMI object:

$size = ([wmi]"\\remotecomputer\root\cimv2:Win32_logicalDisk.DeviceID='c:'").Size
$free = ([wmi]"\\remotecomputer\root\cimv2:Win32_logicalDisk.DeviceID='c:'").FreeSpace

Also you can divide the results by 1GB or 1MB if you want different units:

$disk = ([wmi]"\\remotecomputer\root\cimv2:Win32_logicalDisk.DeviceID='c:'")
"Remotecomputer C: has {0:#.0} GB free of {1:#.0} GB Total" -f ($disk.FreeSpace/1GB),($disk.Size/1GB) | write-output

Output is: Remotecomputer C: has 252.7 GB free of 298.0 GB Total

Guys in my case none of the solutions above worked.

I had to delete the files within the Project workspace:

• .project
• .classpath

And the folder:

• .settings

Then I copied the ones from a similar project that was working before. This managed to fix my broken project.

Of course do not use this method before trying the previous alternatives!.

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

# du -a /var | sort -n -r | head -n 10

If you want more human readable output try:

$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10

Where,

• Var is the directory you wan to search
• du command -h option : display sizes in human readable format (e.g., 1K, 234M, 2G).
• du command -s option : show only a total for each argument (summary).
• du command -x option : skip directories on different file systems.
• sort command -r option : reverse the result of comparisons.
• sort command -h option : compare human readable numbers. This is GNU sort specific option only.
• head command -10 OR -n 10 option : show the first 10 lines.

The ports required will be different for your XMPP Server and any XMPP Clients. Most "modern" XMPP Servers follow the defined IANA Ports for Server-to-Server 5269 and for Client-to-Server 5222. Any additional ports depends on what features you enable on the Server, i.e. if you offer BOSH then you may need to open port 80.

File Transfer is highly dependent on both the Clients you use and the Server as to what port it will use, but most of them also negotiate the connect via your existing XMPP Client-to-Server link so the required port opening will be client side (or proxied via port 80.)

For the future I would recommend Eran Harel's answer (refactoring moving new to factory that can be mocked). But if you don't want to change the original source code, use very handy and unique feature: spies. From the documentation:

You can create spies of real objects. When you use the spy then the real methods are called (unless a method was stubbed).

Real spies should be used carefully and occasionally, for example when dealing with legacy code.

In your case you should write:

TestedClass tc = spy(new TestedClass());
LoginContext lcMock = mock(LoginContext.class);
when(tc.login(anyString(), anyString())).thenReturn(lcMock);

I have created a tool that can accomplish automatic semantic versioning based on the tags in commit messages, known as change types. This closely follows the Angular Commit Message Convention along with the Semantic Versioning Specification.

You could use this tool to automatically change the version in the package.json using the npm CLI (this is described here).

In addition, it can create a changelog from these commits and also has a menu (with a spell checker for commit messages) for creating commits based on the change type. I highly recommend checking it out and reading to docs to see everything that can be accomplished with it.

I wrote the tool because I couldn't find anything that suited my needs for my CICD Pipeline to automate semantic versioning. I'd rather focus on what the actual changes are than what the version should be and that's where my tool saves the day.

For more information on the rationale for the tool, please see this.

From the python command prompt:

import scipy
print scipy.__version__

In python 3 you'll need to change it to:

print (scipy.__version__)

If you are using PHPMyAdmin You can be solved this issue by doing this:

CAUTION: Don't use this solution if you want to maintain existing records in your table.

Step 1: Select database export method to custom:

Step 2: Please make sure to check truncate table before insert in data creation options:

Now you are able to import this database successfully.

Yes, It is called the for-each loop. Objects in the collectionName will be assigned one after one from the beginning of that collection, to the created object reference, 'objectName'. So in each iteration of the loop, the 'objectName' will be assigned an object from the 'collectionName' collection. The loop will terminate once when all the items(objects) of the 'collectionName' Collection have finished been assigning or simply the objects to get are over.

for (ObjectType objectName : collectionName.getObjects()){ //loop body> //You can use the 'objectName' here as needed and different objects will be //reepresented by it in each iteration. }

I have also read that for some servers one for example needs only annotate persistence contexts, but in some servers, the injection should be done manually.

Actually my solution to this problem was much simpler, because I already had the latest version of PowerShell and is still didn't recognize Install-Module command. What fixed the "issue" for me was just typing the command manually, since originally I tried copying the snippet from a website and apparently there was some issue with the formatting when copy&pasting, so when I typed the command manually it installed the module without any problem.

My recommendation is Virtuous Ten Studio. The tool is free but they suggest a donation. It combines all the necessary steps (unpacking APK, baksmaliing, decompiling, etc.) into one easy-to-use UI-based import process. Within five minutes you should have Java source code, less than it takes to figure out the command line options of one of the above mentioned tools.

Decompiling smali to Java is an inexact process, especially if the smali artifacts went through an obfuscator. You can find several decompilers on the web but only some of them are still maintained. Some will give you better decompiled code than others. Read "better" as in "more understandable" than others. Don't expect that the reverse-engineered Java code will compile out of the box. Virtuous Ten Studio comes with multiple free Java decompilers built-in so you can easily try out different decompilers (the "Generate Java source" step) to see which one gives you the best results, saving you the time to find those decompilers yourself and figure out how to use them. Amongst them is CFR, which is one of the few free and still maintained decompilers.

As output you receive, amongst other things, a folder structure that contains all the decompiled Java source code. You can then import this into IntelliJ IDEA or Eclipse for further editing, analysis (e.g. Go to definition, Find usages), etc.

I made this useful table with all the cases:

blank?, present? are provided by Rails.

No need to use for loop. It can be directly applied to a column of a dataframe

sleepstudy['Reaction'] = sleepstudy['Reaction'].round(1)

For special characters:

var iChars = "!@#$%^&*()+=-[]\\\';,./{}|\":<>?";

for (var i = 0; i < document.formname.fieldname.value.length; i++) {
    if (iChars.indexOf(document.formname.fieldname.value.charAt(i)) != -1) {
        alert ("Your username has special characters. \nThese are not allowed.\n Please remove them and try again.");
        return false;
    }
}

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

I am using the Asp.Net Core angular template project with an Angular 4 front end and webpack. I had to use '/dist/assets/images/' in front of the image name, and store the image in the assets/images directory in the dist directory. eg:

 <img  class="img-responsive" src="/dist/assets/images/UnitBadge.jpg">

An easy solution, if you've got ES6, uses Set:

function checkIfArrayIsUnique(myArray) {_x000D_
  return myArray.length === new Set(myArray).size;_x000D_
}_x000D_
_x000D_
let uniqueArray = [1, 2, 3, 4, 5];_x000D_
console.log(`${uniqueArray} is unique : ${checkIfArrayIsUnique(uniqueArray)}`);_x000D_
_x000D_
let nonUniqueArray = [1, 1, 2, 3, 4, 5];_x000D_
console.log(`${nonUniqueArray} is unique : ${checkIfArrayIsUnique(nonUniqueArray)}`);

Everyone appears to be opening their connections entirely too early? I had this same question, and after digging through the Source here - https://github.com/StackExchange/dapper-dot-net/blob/master/Dapper/SqlMapper.cs

You will find that every interaction with the database checks the connection to see if it is closed, and opens it as necessary. Due to this, we simply utilize using statements like above without the conn.open(). This way the connection is opened as close to the interaction as possible. If you notice, it also immediately closes the connection. This will also be quicker than it closing automatically during disposal.

One of the many examples of this from the repo above:

    private static int ExecuteCommand(IDbConnection cnn, ref CommandDefinition command, Action<IDbCommand, object> paramReader)
    {
        IDbCommand cmd = null;
        bool wasClosed = cnn.State == ConnectionState.Closed;
        try
        {
            cmd = command.SetupCommand(cnn, paramReader);
            if (wasClosed) cnn.Open();
            int result = cmd.ExecuteNonQuery();
            command.OnCompleted();
            return result;
        }
        finally
        {
            if (wasClosed) cnn.Close();
            cmd?.Dispose();
        }
    }

Below is a small example of how we use a Wrapper for Dapper called the DapperWrapper. This allows us to wrap all of the Dapper and Simple Crud methods to manage connections, provide security, logging, etc.

  public class DapperWrapper : IDapperWrapper
  {
    public IEnumerable<T> Query<T>(string query, object param = null, IDbTransaction transaction = null, bool buffered = true, int? commandTimeout = null, CommandType? commandType = null)
    {
      using (var conn = Db.NewConnection())
      {
          var results = conn.Query<T>(query, param, transaction, buffered, commandTimeout, commandType);
          // Do whatever you want with the results here
          // Such as Security, Logging, Etc.
          return results;
      }
    }
  }

Might found a solution very easy which you only need to create different type of
. Seem to have worked for me.

example : (html code)

<br/ class="150%space">

(css code)

br[class='150%space']
{
   line-height: 150%;
}

Try the following

var original = 'www.test.com';
var stripped = original.substring(4);

I faced this problem on the formative project of my young career.

The approach I took was to save the values and the names of the enumeration externally, and the end goal was to be able to write code that looked as close to a language enum as possible.

I wanted my solution to look like this:

enum HatType
{
    BASEBALL,
    BRIMLESS,
    INDIANA_JONES
}

HatType mine = HatType.BASEBALL;

// prints "BASEBALL"
System.out.println(mine.toString());

// prints true
System.out.println(mine.equals(HatType.BASEBALL));

And I ended up with something like this:

// in a file somewhere:
// 1 --> BASEBALL
// 2 --> BRIMLESS
// 3 --> INDIANA_JONES

HatDynamicEnum hats = HatEnumRepository.retrieve();

HatEnumValue mine = hats.valueOf("BASEBALL");

// prints "BASEBALL"
System.out.println(mine.toString());

// prints true
System.out.println(mine.equals(hats.valueOf("BASEBALL"));

Since my requirements were that it had to be possible to add members to the enum at run-time, I also implemented that functionality:

hats.addEnum("BATTING_PRACTICE");

HatEnumRepository.storeEnum(hats);

hats = HatEnumRepository.retrieve();

HatEnumValue justArrived = hats.valueOf("BATTING_PRACTICE");
// file now reads:
// 1 --> BASEBALL
// 2 --> BRIMLESS
// 3 --> INDIANA_JONES
// 4 --> BATTING_PRACTICE

I dubbed it the Dynamic Enumeration "pattern", and you read about the original design and its revised edition.

The difference between the two is that the revised edition was designed after I really started to grok OO and DDD. The first one I designed when I was still writing nominally procedural DDD, under time pressure no less.

This is simple when doing 2 things:

1. setting the automatic height

tableView.rowHeight = UITableView.automaticDimension

2. creating all TableViewCells with FULL constraints from top to bottom. The last element MUST define some bottom spacing to end the cell.

So the layout engine can compute the cell heigth and apply the value correctly.

Inline methods are simply a compiler optimization where the code of a function is rolled into the caller.

There's no mechanism by which to do this in C#, and they're to be used sparingly in languages where they are supported -- if you don't know why they should be used somewhere, they shouldn't be.

Edit: To clarify, there are two major reasons they need to be used sparingly:

1. It's easy to make massive binaries by using inline in cases where it's not necessary
2. The compiler tends to know better than you do when something should, from a performance standpoint, be inlined

It's best to leave things alone and let the compiler do its work, then profile and figure out if inline is the best solution for you. Of course, some things just make sense to be inlined (mathematical operators particularly), but letting the compiler handle it is typically the best practice.

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

You can achieve this like following :

map<string, int>::iterator it;

for (it = symbolTable.begin(); it != symbolTable.end(); it++)
{
    std::cout << it->first    // string (key)
              << ':'
              << it->second   // string's value 
              << std::endl;
}

With C++11 _{( and onwards )},

for (auto const& x : symbolTable)
{
    std::cout << x.first  // string (key)
              << ':' 
              << x.second // string's value 
              << std::endl;
}

With C++17 _{( and onwards )},

for (auto const& [key, val] : symbolTable)
{
    std::cout << key        // string (key)
              << ':'  
              << val        // string's value
              << std::endl;
}

Sometimes, it can be caused by wrong naming for xml or resource file.

At least, for me, that problem was solved by changing name .

You don't have to use CASE...WHEN, you could use an OR condition, like this:

WHERE
  pw='correct'
  AND (id>=800 OR success=1) 
  AND YEAR(timestamp)=2011

this means that if id<800, success has to be 1 for the condition to be evaluated as true. Otherwise, it will be true anyway.

It is less common, however you could still use CASE WHEN, like this:

WHERE
  pw='correct'
  AND CASE WHEN id<800 THEN success=1 ELSE TRUE END 
  AND YEAR(timestamp)=2011

this means: return success=1 (which can be TRUE or FALSE) in case id<800, or always return TRUE otherwise.

I think I've found a way for UI Tabs without redoing the functionality. So far I haven't found any problems.

    $( ".tabs" ).tabs();
    $( ".tabs" ).not(".noHash").bind("tabsshow", function(event, ui) { 
        window.location.hash = "tab_"+ui.tab.hash.replace(/#/,"");
        return false;
    });

    var selectedTabHash = window.location.hash.replace(/tab_/,"");
    var index = $( ".tabs li a" ).index($(".tabs li a[href='"+selectedTabHash+"']"));
    $( ".tabs" ).not(".noHash").tabs('select', index);

All within a ready event. It prepends "tab_" for the hash but work both when clicked and page loaded with hash.

it is different for different icons.(eg, diff sizes for action bar icons, laucnher icons, etc.) please follow this link icons handbook to learn more.

<script>
var deg = 0

function rotate(id)
{
    deg = deg+45;
    var txt = 'rotate('+deg+'deg)';
    $('#'+id).css('-webkit-transform',txt);
}
</script>

What I do is something very easy... declare a global variable at the start... and then increment the variable however much I like, and use .css of jquery to increment.

You should use method listName.isEmpty()

1 line solution in Java 8:

public Date getCurrentUtcTime() {
    return Date.from(Instant.now());
}

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

You could do something like:

>>> from time import gmtime, strftime
>>> strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())
'Thu, 28 Jun 2001 14:17:15 +0000'

The full doc on the % codes are at http://docs.python.org/library/time.html

Sort the arrays and compare their values one by one.

function arrayCompare(_arr1, _arr2) {
    if (
      !Array.isArray(_arr1)
      || !Array.isArray(_arr2)
      || _arr1.length !== _arr2.length
      ) {
        return false;
      }
    
    // .concat() to not mutate arguments
    const arr1 = _arr1.concat().sort();
    const arr2 = _arr2.concat().sort();
    
    for (let i = 0; i < arr1.length; i++) {
        if (arr1[i] !== arr2[i]) {
            return false;
         }
    }
    
    return true;
}

My case is different, it fails because of the scope of 'this':

//this fails:
$("#My-Dialog").dialog({
  ...
  close: ()=>{
    $(this).dialog("close");
  }
});

//this works:
$("#My-Dialog").dialog({
  ...
  close: function(){
    $(this).dialog("close");
  }
});

For me, it happens when i set Project SDK as JAVA SDK 14 in a react-native project. Upon unset, all the folders show up again.

    cerr << sizeof(0) << endl;
    cerr << sizeof(NULL) << endl;
    cerr << sizeof(void*) << endl;

    ============
    On a 64-bit gcc RHEL platform you get:
    4
    8
    8
    ================

The moral of the story. You should use NULL when you're dealing with pointers.

1) It declares your intent (don't make me search through all your code trying to figure out if a variable is a pointer or some numeric type).

2) In certain API calls that expect variable arguments, they'll use a NULL-pointer to indicate the end of the argument list. In this case, using a '0' instead of NULL can cause problems. On a 64-bit platform, the va_arg call wants a 64-bit pointer, yet you'll be passing only a 32-bit integer. Seems to me like you're relying on the other 32-bits to be zeroed out for you? I've seen certain compilers (e.g. Intel's icpc) that aren't so gracious -- and this has resulted in runtime errors.

Just put this blur view on the imageView. Here is an example in Objective-C:

UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

visualEffectView.frame = imageView.bounds;
[imageView addSubview:visualEffectView];

and Swift:

var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light))    

visualEffectView.frame = imageView.bounds

imageView.addSubview(visualEffectView)

Here is my performant approach to paging when using LINQ to objects:

public static IEnumerable<IEnumerable<T>> Page<T>(this IEnumerable<T> source, int pageSize)
{
    Contract.Requires(source != null);
    Contract.Requires(pageSize > 0);
    Contract.Ensures(Contract.Result<IEnumerable<IEnumerable<T>>>() != null);

    using (var enumerator = source.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            var currentPage = new List<T>(pageSize)
            {
                enumerator.Current
            };

            while (currentPage.Count < pageSize && enumerator.MoveNext())
            {
                currentPage.Add(enumerator.Current);
            }
            yield return new ReadOnlyCollection<T>(currentPage);
        }
    }
}

This can then be used like so:

var items = Enumerable.Range(0, 12);

foreach(var page in items.Page(3))
{
    // Do something with each page
    foreach(var item in page)
    {
        // Do something with the item in the current page       
    }
}

None of this rubbish Skip and Take which will be highly inefficient if you are interested in multiple pages.

The field nbytes will give you the size in bytes of all the elements of the array in a numpy.array:

size_in_bytes = my_numpy_array.nbytes

Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger than this.

I have face the same problem and after times of trial and error, I found out that you can avoid scrollbars by overriding frame css class.

You can do like this:

iframe.fancybox-iframe {
    overflow:hidden;
}

JS configuration:

jQuery(document).ready(function(){
    $("a.various").fancybox({
        'width'             : 'auto',
        'height'            : 'auto',
        'autoScale'         : false,
        'autoDimensions'    : false,
        'scrolling'         : 'no',
        'transitionIn'      : 'none',
        'transitionOut'     : 'none',
        'type'              : 'iframe'  
    }); 
});

Note: Your fancybox box type must be an iframe for this to take effect.

Ant is mainly a build tool.

Maven is a project and dependencies management tool (which of course builds your project as well).

Ant+Ivy is a pretty good combination if you want to avoid Maven.

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

And here's my final version.

public static class MyWpfExtensions
{
    public static System.Windows.Forms.IWin32Window GetIWin32Window(this System.Windows.Media.Visual visual)
    {
        var source = System.Windows.PresentationSource.FromVisual(visual) as System.Windows.Interop.HwndSource;
        System.Windows.Forms.IWin32Window win = new OldWindow(source.Handle);
        return win;
    }

    private class OldWindow : System.Windows.Forms.IWin32Window
    {
        private readonly System.IntPtr _handle;
        public OldWindow(System.IntPtr handle)
        {
            _handle = handle;
        }

        #region IWin32Window Members
        System.IntPtr System.Windows.Forms.IWin32Window.Handle
        {
            get { return _handle; }
        }
        #endregion
    }
}

And to actually use it:

var dlg = new FolderBrowserDialog();
System.Windows.Forms.DialogResult result = dlg.ShowDialog(this.GetIWin32Window());

It presents a prompt to the user (the optional arg of raw_input([arg])), gets input from the user and returns the data input by the user in a string. See the docs for raw_input().

Example:

name = raw_input("What is your name? ")
print "Hello, %s." % name

This differs from input() in that the latter tries to interpret the input given by the user; it is usually best to avoid input() and to stick with raw_input() and custom parsing/conversion code.

Note: This is for Python 2.x

NetBeans, Context-Click

In NetBeans 8 with a Maven-driven project, merely context-click on the jar file list item of the dependency in which you are interested. Choose Download Sources. Wait a moment and NetBeans will automatically download and install the source code, if available.

Similarly you can choose Download Javadoc to get the doc locally installed. Then you can context-click some code in the editor and choose to see the JavaDoc.

Basics

You may not know it but, in JavaScript, whenever we interact with string, number or boolean primitives we enter a hidden world of object shadows and coercion.

string, number, boolean, null, undefined, and symbol.

In JavaScript there are 7 primitive types: undefined, null, boolean, string, number, bigint and symbol. Everything else is an object. The primitive types boolean, string and number can be wrapped by their object counterparts. These objects are instances of the Boolean, String and Number constructors respectively.

typeof true; //"boolean"
typeof new Boolean(true); //"object"

typeof "this is a string"; //"string"
typeof new String("this is a string"); //"object"

typeof 123; //"number"
typeof new Number(123); //"object"

If primitives have no properties, why does "this is a string".length return a value?

Because JavaScript will readily coerce between primitives and objects. In this case the string value is coerced to a string object in order to access the property length. The string object is only used for a fraction of second after which it is sacrificed to the Gods of garbage collection – but in the spirit of the TV discovery shows, we will trap the elusive creature and preserve it for further analysis…

To demonstrate this further consider the following example in which we are adding a new property to String constructor prototype.

String.prototype.sampleProperty = 5;
var str = "this is a string";
str.sampleProperty;            // 5

By this means primitives have access to all the properties (including methods) defined by their respective object constructors.

So we saw that primitive types will appropriately coerce to their respective Object counterpart when required.

Analysis of toString() method

Consider the following code

var myObj    = {lhs: 3, rhs: 2};
var myFunc   = function(){}
var myString = "This is a sample String";
var myNumber = 4;
var myArray  = [2, 3, 5];

myObj.toString();     // "[object Object]"
myFunc.toString();    // "function(){}"
myString.toString();  // "This is a sample String"
myNumber.toString();  // "4"
myArray.toString();   // "2,3,5"

As discussed above, what's really happening is when we call toString() method on a primitive type, it has to be coerced into its object counterpart before it can invoke the method.
i.e. myNumber.toString() is equivalent to Number.prototype.toString.call(myNumber) and similarly for other primitive types.

But what if instead of primitive type being passed into toString() method of its corresponding Object constructor function counterpart, we force the primitive type to be passed as parameter onto toString() method of Object function constructor (Object.prototype.toString.call(x))?

Closer look at Object.prototype.toString()

As per the documentation, When the toString method is called, the following steps are taken:

1. If the this value is undefined, return "[object Undefined]".
2. If the this value is null, return "[object Null]".
3. If this value is none of the above, Let O be the result of calling toObject passing the this value as the argument.
4. Let class be the value of the [[Class]] internal property of O.
5. Return the String value that is the result of concatenating the three Strings "[object ", class, and "]".

Understand this from the following example

var myObj       = {lhs: 3, rhs: 2};
var myFunc      = function(){}
var myString    = "This is a sample String";
var myNumber    = 4;
var myArray     = [2, 3, 5];
var myUndefined = undefined;
var myNull      = null;

Object.prototype.toString.call(myObj);        // "[object Object]"
Object.prototype.toString.call(myFunc);       // "[object Function]"
Object.prototype.toString.call(myString);     // "[object String]"
Object.prototype.toString.call(myNumber);     // "[object Number]"
Object.prototype.toString.call(myArray);      // "[object Array]"
Object.prototype.toString.call(myUndefined);  // "[object Undefined]"
Object.prototype.toString.call(myNull);       // "[object Null]"

If You need sth different than AUTO_INCREMENT you can still use triggers.

Making Node.js code sync is essential in few aspects such as database. But actual advantage of Node.js lies in async code. As it is single thread non-blocking.

we can sync it using important functionality Fiber() Use await() and defer () we call all methods using await(). then replace the callback functions with defer().

Normal Async code.This uses CallBack functions.

function add (var a, var b, function(err,res){
       console.log(res);
});

 function sub (var res2, var b, function(err,res1){
           console.log(res);
    });

 function div (var res2, var b, function(err,res3){
           console.log(res3);
    });

Sync the above code using Fiber(), await() and defer()

fiber(function(){
     var obj1 = await(function add(var a, var b,defer()));
     var obj2 = await(function sub(var obj1, var b, defer()));
     var obj3 = await(function sub(var obj2, var b, defer()));

});

I hope this will help. Thank You

The absolute simplest way to accomplish this, is with basename()

echo basename('http://domain.com/artist/song/music-videos/song-title/9393903');

Which will print

9393903

Of course, if there is a query string at the end it will be included in the returned value, in which case the accepted answer is a better solution.

  kw=(EditText)findViewById(R.id.kw);
    btn=(Button)findViewById(R.id.btn);
    cost=(TextView )findViewById(R.id.cost);


            btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) { cst =  Double.valueOf(kw.getText().toString());
            cst = cst*0.551;
            cost.setText(cst.toString());
        }
    });

One idea would be to save the docker image locally and later load it into minikube as follows:

Let say, for example, you already have puckel/docker-airflow image.

1. Save that image to local disk -

   docker save puckel/docker-airflow > puckel_docker_airflow.tar

2. Now enter into minikube docker env -

   eval $(minikube docker-env)

3. Load that locally saved image -

   docker load < puckel_docker_airflow.tar

It is that simple and it works like a charm.

I assume you have a connection to your database and you can not do the insert parameters using c #.

You are not adding the parameters in your query. It should look like:

String query = "INSERT INTO dbo.SMS_PW (id,username,password,email) VALUES (@id,@username,@password, @email)";

SqlCommand command = new SqlCommand(query, db.Connection);
command.Parameters.Add("@id","abc");
command.Parameters.Add("@username","abc");
command.Parameters.Add("@password","abc");
command.Parameters.Add("@email","abc");

command.ExecuteNonQuery();

Updated:

using(SqlConnection connection = new SqlConnection(_connectionString))
{
    String query = "INSERT INTO dbo.SMS_PW (id,username,password,email) VALUES (@id,@username,@password, @email)";

    using(SqlCommand command = new SqlCommand(query, connection))
    {
        command.Parameters.AddWithValue("@id", "abc");
        command.Parameters.AddWithValue("@username", "abc");
        command.Parameters.AddWithValue("@password", "abc");
        command.Parameters.AddWithValue("@email", "abc");

        connection.Open();
        int result = command.ExecuteNonQuery();

        // Check Error
        if(result < 0)
            Console.WriteLine("Error inserting data into Database!");
    }
}

SetX is the command that you'll need in most of the cases.Though its possible to use REG or REGEDIT

Using registry editing commands you can avoid some of the restrictions of the SetX command - different data types, variables containing = in their name and so on.

@echo off

:: requires admin elevated permissions
::setting system variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v MyVar /D MyVal
::expandable variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /T REG_EXPAND_SZ /v MyVar /D MyVal


:: does not require admin permissions
::setting user variable
REG ADD "HKEY_CURRENT_USER\Environment" /v =C: /D "C:\\test"

REG is the pure registry client but its possible also to import the data with REGEDIT though it allows using only hard coded values (or generation of a temp files). The example here is a hybrid file that contains both batch code and registry data (should be saved as .bat - mind that in batch ; are ignored as delimiters while they are used as comments in .reg files):

REGEDIT4

; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"SystemVariable"="GlobalValue"

[HKEY_CURRENT_USER\Environment]
"UserVariable"="SomeValue"

Syntax errors is not checked easily in external servers, just runtime errors.

What I do? Just like you, I use

ini_set('display_errors', 'On');
error_reporting(E_ALL);

However, before run I check syntax errors in a PHP file using an online PHP syntax checker.

The best, IMHO is PHP Code Checker

I copy all the source code, paste inside the main box and click the Analyze button.

It is not the most practical method, but the 2 procedures are complementary and it solves the problem completely

mmap is great if you have multiple processes accessing data in a read only fashion from the same file, which is common in the kind of server systems I write. mmap allows all those processes to share the same physical memory pages, saving a lot of memory.

mmap also allows the operating system to optimize paging operations. For example, consider two programs; program A which reads in a 1MB file into a buffer creating with malloc, and program B which mmaps the 1MB file into memory. If the operating system has to swap part of A's memory out, it must write the contents of the buffer to swap before it can reuse the memory. In B's case any unmodified mmap'd pages can be reused immediately because the OS knows how to restore them from the existing file they were mmap'd from. (The OS can detect which pages are unmodified by initially marking writable mmap'd pages as read only and catching seg faults, similar to Copy on Write strategy).

mmap is also useful for inter process communication. You can mmap a file as read / write in the processes that need to communicate and then use synchronization primitives in the mmap'd region (this is what the MAP_HASSEMAPHORE flag is for).

One place mmap can be awkward is if you need to work with very large files on a 32 bit machine. This is because mmap has to find a contiguous block of addresses in your process's address space that is large enough to fit the entire range of the file being mapped. This can become a problem if your address space becomes fragmented, where you might have 2 GB of address space free, but no individual range of it can fit a 1 GB file mapping. In this case you may have to map the file in smaller chunks than you would like to make it fit.

Another potential awkwardness with mmap as a replacement for read / write is that you have to start your mapping on offsets of the page size. If you just want to get some data at offset X you will need to fixup that offset so it's compatible with mmap.

And finally, read / write are the only way you can work with some types of files. mmap can't be used on things like pipes and ttys.

To get current host name :-

select @@hostname;
show variables where Variable_name like '%host%';

To get hosts for all incoming requests :-

select host from information_schema.processlist;

Based on your last comment,
I don't think you can resolve IP for the hostname using pure mysql function,
as it require a network lookup, which could be taking long time.

However, mysql document mention this :-

resolveip google.com.sg

docs :- http://dev.mysql.com/doc/refman/5.0/en/resolveip.html

        webView.post(new Runnable() {

                webView.loadUrl("javascript:" + scriptSrc); 
            }

I ran into this page while wondering the same question.

As others have noted, it's simple enough to just grab the __name__ attribute from a function in order to determine the name of the function. It's marginally trickier with objects that don't have a sane way to determine __name__, i.e. base/primitive objects like basestring instances, ints, longs, etc.

Long story short, you could probably use the inspect module to make an educated guess about which one it is, but you would have to probably know what frame you're working in/traverse down the stack to find the right one. But I'd hate to imagine how much fun this would be trying to deal with eval/exec'ed code.

Dear You have used two Intent launcher in your Manifest. Make only one Activity as launcher: Your manifest activity is :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.th.mybook"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".MainTabPanel"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="MyBookActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.ALTERNATIVE" />
            </intent-filter>
        </activity>
    </application>
</manifest>

now write code will be ( i have made your 'MyActivityBook' your default activity launcher. Copy and paste it on your manifest.

<?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="org.th.mybook"
        android:versionCode="1"
        android:versionName="1.0" >
        <uses-sdk android:minSdkVersion="8" />
        <application
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name" >
            <activity
                android:name=".MainTabPanel"
                android:label="@string/app_name" >

            </activity>
            <activity
                android:name="MyBookActivity"
                android:label="@string/app_name" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    </manifest>

and Second error may be if you copy paste old code then please update com.example.packagename.FILE_NAME

hope this will work !

I couldn't get the first method to work, and I know this is an old topic, but this is what I ended up doing for a solution:

=IF(ISNA(MATCH(A1,B:B,0)),"Not Matched", A1)

Basically, MATCH A1 to Column B exactly (the 0 stands for match exactly to a value in Column B). ISNA tests for #N/A response which match will return if the no match is found. Finally, if ISNA is true, write "Not Matched" to the selected cell, otherwise write the contents of the matched cell.

@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.

The below examples are based on a domain in the range of 20,000 account objects.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds           : 16
Milliseconds      : 208

measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds           : 3
Milliseconds      : 496

In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).

Note that if I include the where clause per your suggestion to prune to the actually desired results, it's even more expensive.

measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds           : 17
Milliseconds      : 876

Indexed attributes seem to have similar performance (I tried just returning displayName).

Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).

measure-command {$userlist | get-aduser -Properties *}
...
Seconds           : 12
Milliseconds      : 75

I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01

When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).

If you're using PHP 5.5 you can use a generator. This will NOT work in any version of PHP before 5.5 though. From php.net:

"Generators provide an easy way to implement simple iterators without the overhead or complexity of implementing a class that implements the Iterator interface."

// This function implements a generator to load individual lines of a large file
function getLines($file) {
    $f = fopen($file, 'r');

    // read each line of the file without loading the whole file to memory
    while ($line = fgets($f)) {
        yield $line;
    }
}

// Since generators implement simple iterators, I can quickly count the number
// of lines using the iterator_count() function.
$file = '/path/to/file.txt';
$lineCount = iterator_count(getLines($file)); // the number of lines in the file

with this, you avoid to test a lookahead on each positions:

/^(?:[^h]+|h++(?!ede))*+$/

equivalent to (for .net):

^(?>(?:[^h]+|h+(?!ede))*)$

Old answer:

/^(?>[^h]+|h+(?!ede))*$/

I'm using a popup to show the map in a new window. I'm using the following url

https://www.google.com/maps?z=15&daddr=LATITUDE,LONGITUDE

To receive a pure JSON string, without it being wrapped into an XML, you have to write the JSON string directly to the HttpResponse and change the WebMethod return type to void.

    [System.Web.Script.Services.ScriptService]
    public class WebServiceClass : System.Web.Services.WebService {
        [WebMethod]
        public void WebMethodName()
        {
            HttpContext.Current.Response.Write("{property: value}");
        }
    }

i guess your could use the --name-only flag. something like:

git log 73167b96 --pretty="format:" --name-only

i personally use git show for viewing files changed in a commit

git show --pretty="format:" --name-only 73167b96

(73167b96 could be any commit/tag name)

Here is an example from the Date object docs on the Mozilla Developer Network using a custom "pad" function, without having to extend Javascript's Number prototype. The handy function they give as an example is

function pad(n){return n<10 ? '0'+n : n}

And below is it being used in context.

/* use a function for the exact format desired... */
function ISODateString(d){
    function pad(n){return n<10 ? '0'+n : n}
    return d.getUTCFullYear()+'-'
    + pad(d.getUTCMonth()+1)+'-'
    + pad(d.getUTCDate())+'T'
    + pad(d.getUTCHours())+':'
    + pad(d.getUTCMinutes())+':'
    + pad(d.getUTCSeconds())+'Z'
}

var d = new Date();
console.log(ISODateString(d)); // prints something like 2009-09-28T19:03:12Z

Only people from Microsoft can really answer that question. However, I'd like to offer some fun facts about it ;)

First, this is what it says in MSDN about the Boolean.ToString() method:

Return Value

Type: System.String

TrueString if the value of this instance is true, or FalseString if the value of this instance is false.

Remarks

This method returns the constants "True" or "False". Note that XML is case-sensitive, and that the XML specification recognizes "true" and "false" as the valid set of Boolean values. If the String object returned by the ToString() method is to be written to an XML file, its String.ToLower method should be called first to convert it to lowercase.

Here comes the fun fact #1: it doesn't return TrueString or FalseString at all. It uses hardcoded literals "True" and "False". Wouldn't do you any good if it used the fields, because they're marked as readonly, so there's no changing them.

The alternative method, Boolean.ToString(IFormatProvider) is even funnier:

Remarks

The provider parameter is reserved. It does not participate in the execution of this method. This means that the Boolean.ToString(IFormatProvider) method, unlike most methods with a provider parameter, does not reflect culture-specific settings.

What's the solution? Depends on what exactly you're trying to do. Whatever it is, I bet it will require a hack ;)

For PHP 5.5.27 security update

$file = $path.$filename;
$content = file_get_contents( $file);
$content = chunk_split(base64_encode($content));
$uid = md5(uniqid(time()));
$name = basename($file);

// header
$header = "From: ".$from_name." <".$from_mail.">\r\n";
$header .= "Reply-To: ".$replyto."\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";

// message & attachment
$nmessage = "--".$uid."\r\n";
$nmessage .= "Content-type:text/plain; charset=iso-8859-1\r\n";
$nmessage .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$nmessage .= $message."\r\n\r\n";
$nmessage .= "--".$uid."\r\n";
$nmessage .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n";
$nmessage .= "Content-Transfer-Encoding: base64\r\n";
$nmessage .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
$nmessage .= $content."\r\n\r\n";
$nmessage .= "--".$uid."--";

if (mail($mailto, $subject, $nmessage, $header)) {
    return true; // Or do something here
} else {
  return false;
}

The example above can be simplify a bit. Additionally you can put date manually from keyboard instead of selecting it via datepicker only. When clearing the value you need to handle also 'on clearDate' action to remove startDate/endDate boundary:

JS file:

$(".from_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var startDate = new Date(selected.date.valueOf());
    $('.to_date').datepicker('setStartDate', startDate);
}).on('clearDate', function (selected) {
    $('.to_date').datepicker('setStartDate', null);
});

$(".to_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var endDate = new Date(selected.date.valueOf());
    $('.from_date').datepicker('setEndDate', endDate);
}).on('clearDate', function (selected) {
    $('.from_date').datepicker('setEndDate', null);
});

HTML:

<input class="from_date" placeholder="Select start date" type="text" name="from_date">
<input class="to_date" placeholder="Select end date" type="text" name="to_date">

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

Try this: edited

@echo off
set "comd=dir /b /s *.zip"
set "pathName="
set /p "pathName=Enter The Value: "
cd /d "%pathName%"
%comd%
pause

You can check whether it exists and, if it does not exist, load it dynamically.

function loadScript(src) {
    return new Promise(function (resolve, reject) {
        var s;
        s = document.createElement('script');
        s.src = src;
        s.onload = resolve;
        s.onerror = reject;
        document.head.appendChild(s);
    });
}



async function load(){
if (!window.jQuery){
    await loadScript(`https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js`);
}

console.log(jQuery);

}

load();

You can use jQuery toggle to show and hide the div. The script will be like this

  <script type="text/javascript">
    jQuery(function(){
      jQuery("#music").click(function () {
        jQuery("#musicinfo").toggle("slow");
      });
    });
</script>

I had the same scenario occuring..Very basic report, the SP (which only takes in 1 param) was taking 5 seconds to bring back 10K records, yet the report would take 6 minutes to run. According to profiler and the RS ExecutionLogStorage table, the report was spending all it's time on the query. Brian S.'s comment led me to the solution..I simply added WITH RECOMPILE before the AS statement in the SP, and now the report time pretty much matches the SP execution time.

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
for i,price in enumerate(PriceList):
  PriceList[i] = PizzaChange + 3*int(i>=7)

Use modulus:

function isEven(n) {
   return n % 2 == 0;
}

function isOdd(n) {
   return Math.abs(n % 2) == 1;
}

You can check that any value in Javascript can be coerced to a number with:

Number.isFinite(parseFloat(n))

This check should preferably be done outside the isEven and isOdd functions, so you don't have to duplicate error handling in both functions.

Just remember that with this method each console.log call will still do a call to a (empty) function causing overhead, if there are 100 console.log commands, you are still doing 100 calls to a blank function.

Not sure how much overhead this would cause, but there will be some, it would be preferable to have a flag to turn debug on then use something along the lines of:

var debug=true; if (debug) console.log('blah')

Running:

npm install

from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).

You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.

To prevent this, just create a symlink to the relocated node_modules from your app dir:

ln -s ../node_modules node_modules

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

You can print to file and at the same time see progress having (or not) screen, while running a R script.

When not using screen, use R CMD BATCH yourscript.R & and step 4.

1. When using screen, in a terminal, start screen

    screen
   

2. run your R script

    R CMD BATCH yourscript.R
   

3. Go to another screen pressing CtrlA, then c

4. look at your output with (real-time):

    tail -f yourscript.Rout
   

5. Switch among screens with CtrlA then n

You can use below code to get all the privileges list from all users.

Here are the primary differences:

Services

Syntax: module.service( 'serviceName', function );

Result: When declaring serviceName as an injectable argument you will be provided with the instance of a function passed to module.service.

Usage: Could be useful for sharing utility functions that are useful to invoke by simply appending ( ) to the injected function reference. Could also be run with injectedArg.call( this ) or similar.

Factories

Syntax: module.factory( 'factoryName', function );

Result: When declaring factoryName as an injectable argument you will be provided with the value that is returned by invoking the function reference passed to module.factory.

Usage: Could be useful for returning a 'class' function that can then be new'ed to create instances.

Here is example using services and factory. Read more about AngularJS Service vs Factory.

You can also check the AngularJS documentation and similar question on stackoverflow confused about service vs factory.

As long as your list is initialized with values and that value actually exists in the list, then Contains should return true.

I tried the following:

var list = new List<int> {1,2,3,4,5};
var intVar = 4;
var exists = list.Contains(intVar);

And exists is indeed set to true.

I've been using this answer to great effect: Get the property, as a string, from an Expression<Func<TModel,TProperty>>

I realize I already answered this question a while back. The only advantage my other answer has is that it works for static properties. I find the syntax in this answer much more useful because you don't have to create a variable of the type you want to reflect.

PEP 8 advises the first form for readability. You can find it here.

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

Worked for me: in the begining it worked and after a while went to offline. I did the follwong: adb kill-server adb start-server. Plug the phone again with usb to PC adb devices, output of empty list provided. adb tcpip 5555, adb connect <mobile wifi ip address> Then it became online again.

I had the same problem, today 2016 - october - 06 I solved with this:

I changed all dependencies that began with 9.?.? to 9.6.1 I compiled with sdk version 24 and target version 17.

There is another packages in my solution because I used more things then only authentication.

After changed your build.gradle (Module:app) with the code below do it:

1. Put your package NAME in the line with the words applicationId "com.YOUR_PACKAGE_HERE"

2. Synchronize your project (Ctrl+alt+v) and Build Again.

This is the code of the file buid.gradle (Module:app) that worked for me:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    defaultConfig {
        applicationId "com.YOUR_PACKAGE_HERE"
        minSdkVersion 24
        targetSdkVersion 17
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.google.firebase:firebase-core:9.6.1'
    compile 'com.google.firebase:firebase-database:9.6.1'

    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'

    compile 'com.google.firebase:firebase-crash:9.6.1'
    testCompile 'junit:junit:4.12'

    compile 'com.google.firebase:firebase-messaging:9.6.1'

    compile 'com.google.firebase:firebase-ads:9.6.1'


    compile 'com.google.firebase:firebase-auth:9.6.1'


    compile 'com.google.android.gms:play-services:9.6.1'

}
apply plugin: 'com.google.gms.google-services'

AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.

As the OP specifically asked for a jQuery implementation, here you go:

<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
    <input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
    <button>Upload!</button>
</form>

$('#upload').submit(function(e) {
    e.preventDefault(); // stop the standard form submission

    $.ajax({
        url: this.action,
        type: this.method,
        data: new FormData(this),
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
        },
        error: function(xhr, error, status) {
            console.log(error, status);
        }
    });
});

public JsonResult Survey()
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        var file = Request.Files[i];
        // save file as required here...
    }
    return Json(new { UploadedFileCount = Request.Files.Count });
}

You can use read-tree to read or merge a given remote tree into the current index, for example:

git remote add foo [email protected]/foo.git
git fetch foo
git read-tree --prefix=my-folder/ -u foo/master:trunk/their-folder

To perform the merge, use -m instead.

The unix setup should be like the following:

 0 */3 * * * sh cron/update_old_citations.sh

good reference for how to set various settings in cron at: http://www.thegeekstuff.com/2011/07/cron-every-5-minutes/

You can use this and then you can add just a class form from bootstrap. ^{(does not matter which version)}

<div class="form-group">
 <label >Begin voorverkoop periode</label>
 <input type="date" name="bday" max="3000-12-31" 
        min="1000-01-01" class="form-control">
</div>
<div class="form-group">
 <label >Einde voorverkoop periode</label>
 <input type="date" name="bday" min="1000-01-01"
        max="3000-12-31" class="form-control">
</div>

Non-javascript way . . aspx page:

 <form id="form1" runat="server">
<div>
    <asp:CheckBox ID="CheckBox1" runat="server" />
    <asp:CustomValidator ID="CustomValidator1"
        runat="server" ErrorMessage="CustomValidator" ControlToValidate="CheckBox1"></asp:CustomValidator>
</div>
</form>

Code Behind:

Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    If Not CheckBox1.Checked Then
        args.IsValid = False
    End If
End Sub

For any actions you might need (business Rules):

If Page.IsValid Then
   'do logic
End If 

Sorry for the VB code . . . you can convert it to C# if that is your pleasure. The company I am working for right now requires VB :(

You cannot instantiate an abstract class, Jackson neither. You should give Jackson information on how to instantiate MyAbstractClass with a concrete type.

See this answer on stackoverflow: Jackson JSON library: how to instantiate a class that contains abstract fields

And maybe also see Jackson Polymorphic Deserialization

if you can use HTML5 you can do <input type="number" /> If not you will have to either do it through javascript as you said it doesnt get submited to do it from codebehind.

<input id="numbersOnly" onkeypress='validate()' />

function validate(){
  var returnString;
  var text = document.getElementByID('numbersOnly').value;
  var regex = /[0-9]|\./;
  var anArray = text.split('');
  for(var i=0; i<anArray.length; i++){
   if(!regex.test(anArray[i]))
   {
     anArray[i] = '';
   }
  }
  for(var i=0; i<anArray.length; i++) {
    returnString += anArray[i];
  }
  document.getElementByID('numbersOnly').value = returnString;
}

P.S didnt test the code but it should be more or less correct if not check for typos :D You might wanna add a few more things like what to do if the string is null or empty etc. Also you could make this quicker :D

It should be considered an error. But C is an ancient language, so it's only a warning.
Compiling with -Werror (gcc) fixes this problem.

When C doesn't find a declaration, it assumes this implicit declaration: int f();, which means the function can receive whatever you give it, and returns an integer. If this happens to be close enough (and in case of printf, it is), then things can work. In some cases (e.g. the function actually returns a pointer, and pointers are larger than ints), it may cause real trouble.

Note that this was fixed in newer C standards (C99, C11). In these standards, this is an error. However, gcc doesn't implement these standards by default, so you still get the warning.

Live Plotting

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2 * np.pi, 100)
# plt.axis([x[0], x[-1], -1, 1])      # disable autoscaling
for point in x:
    plt.plot(point, np.sin(2 * point), '.', color='b')
    plt.draw()
    plt.pause(0.01)
# plt.clf()                           # clear the current figure

if the amount of data is too much you can lower the update rate with a simple counter

cnt += 1
if (cnt == 10):       # update plot each 10 points
    plt.draw()
    plt.pause(0.01)
    cnt = 0

Holding Plot after Program Exit

This was my actual problem that couldn't find satisfactory answer for, I wanted plotting that didn't close after the script was finished (like MATLAB),

If you think about it, after the script is finished, the program is terminated and there is no logical way to hold the plot this way, so there are two options

1. block the script from exiting (that's plt.show() and not what I want)
2. run the plot on a separate thread (too complicated)

this wasn't satisfactory for me so I found another solution outside of the box

SaveToFile and View in external viewer

For this the saving and viewing should be both fast and the viewer shouldn't lock the file and should update the content automatically

Selecting Format for Saving

vector based formats are both small and fast

• SVG is good but coudn't find good viewer for it except the web browser which by default needs manual refresh
• PDF can support vector formats and there are lightweight viewers which support live updating

Fast Lightweight Viewer with Live Update

For PDF there are several good options

• On Windows I use SumatraPDF which is free, fast and light (only uses 1.8MB RAM for my case)

• On Linux there are several options such as Evince (GNOME) and Ocular (KDE)

Sample Code & Results

Sample code for outputing plot to a file

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(2 * x)
plt.plot(x, y)
plt.savefig("fig.pdf")

after first run, open the output file in one of the viewers mentioned above and enjoy.

Here is a screenshot of VSCode alongside SumatraPDF, also the process is fast enough to get semi-live update rate (I can get near 10Hz on my setup just use time.sleep() between intervals)

Here :)

function isSet(iVal){
 return (iVal!=="" && iVal!=null && iVal!==undefined && typeof(iVal) != "undefined") ? 1 : 0;
} // Returns 1 if set, 0 false

You can set the value property using client script after the element is created:

<input type="text" id="fee" />

<script type="text/javascript>
document.getElementById('fee').value = '1000';
</script>

In addition:

AppDomain.CurrentDomain.BaseDirectory
Assembly.GetEntryAssembly().Location

It worked by simply replacing the <embed/> tag with <img/> and deleting the type attribute.

For instance, in my code, instead of:

<embed src=\"./images/info_09c.svg\" type=\"image/svg+xml\" width=\"45\" onClick='afiseaza_indicatie($i, \"$indicatii[$i]\")'> 

which does not answer the clicking, I wrote:

<img src=\"./images/info_09c.svg\" height=\"25\" width=\"25\" onClick='afiseaza_indicatie($i, \"$indicatii[$i]\")'> 

It works in Internet Explorer and Google Chrome, and I hope that in the other browsers too.

I have this problem in Mozilla. All time: Error: Unknown error acquiring position.

Now i'm using 47 Mozilla. I have tried everything, but all time this problem. BUT then i open about:config in my addsress bar, go geo.wifi.ui and changed it value to "https://location.services.mozilla.com/v1/geolocate?key=test". works!

If u have Position acquisition timed out error, try to increase timeout value:

var options = {
  enableHighAccuracy: true,
  timeout: 5000,
  maximumAge: 0       
};
navigator.geolocation.getCurrentPosition(success, error, options);

Had this issue too. Invalidating Caches/Restart did the trick for me. Please upvote so the the IntelliJ folks take this more seriously. This gives the IDE a terrible UI/UX experience.

https://youtrack.jetbrains.com/issue/IDEA-203100

from python mailing lists: parsing millisecond thread. There is a function posted there that seems to get the job done, although as mentioned in the author's comments it is kind of a hack. It uses regular expressions to handle the exception that gets raised, and then does some calculations.

You could also try do the regular expressions and calculations up front, before passing it to strptime.

Try json_dto. It is header-only and easy to use.

Simple example:

struct message_t
{
  std::string m_from;
  std::string m_text;

  // Entry point for json_dto.
  template < typename JSON_IO >
  void
  json_io( JSON_IO & io )
  {
    io
      & json_dto::mandatory( "from", m_from )
      & json_dto::mandatory( "text", m_text );
  }
};

This will be convertable to and from JSON:

{ "from" : "json_dto", "text" : "Hello world!" }

Yes, they can throw exceptions. If so, they will only be partially initialized and if non-final, subject to attack.

The following is from the Secure Coding Guidelines 2.0.

Partially initialized instances of a non-final class can be accessed via a finalizer attack. The attacker overrides the protected finalize method in a subclass, and attempts to create a new instance of that subclass. This attempt fails (in the above example, the SecurityManager check in ClassLoader's constructor throws a security exception), but the attacker simply ignores any exception and waits for the virtual machine to perform finalization on the partially initialized object. When that occurs the malicious finalize method implementation is invoked, giving the attacker access to this, a reference to the object being finalized. Although the object is only partially initialized, the attacker can still invoke methods on it (thereby circumventing the SecurityManager check).

I resolved issue using below steps :

1. Stop cassandara services

   sudo su -
   systemctl stop datastax-agent
   systemctl stop opscenterd
   systemctl stop app-dse
   

2. Take backup and Change port from 9042 to 9035

   cp /opt/dse/resources/cassandra/conf/cassandra.yaml /opt/dse/resources/cassandra/conf/bkp_cassandra.yaml
   Vi /opt/dse/resources/cassandra/conf/cassandra.yaml
   native_transport_port: 9035
   

3. Start Cassandra services

   systemctl start datastax-agent
   systemctl start opscenterd
   systemctl start app-dse
   

4. create cqlshrc file.

   vi  /root/.cassandra/cqlshrc
   
   [connection]
   hostname = 198.168.1.100
   port = 9035
   

Thanks, Mahesh

For single-threaded programs you can use igprof, The Ignominous Profiler: https://igprof.org/ .

It is a sampling profiler, along the lines of the... long... answer by Mike Dunlavey, which will gift wrap the results in a browsable call stack tree, annotated with the time or memory spent in each function, either cumulative or per-function.

Simple and Complete Solution working for me. Supports ASP.NET MVC 4 and 5 (Supports ASP.NET 4.0, 4.5, and 4.5.1)

Step 1: Install NuGet Package by "Install-Package reCAPTCH.MVC"

Step 2: Add your Public and Private key to your web.config file in appsettings section

<appSettings>
    <add key="ReCaptchaPrivateKey" value=" -- PRIVATE_KEY -- " />
    <add key="ReCaptchaPublicKey" value=" -- PUBLIC KEY -- " />
</appSettings>  

You can create an API key pair for your site at https://www.google.com/recaptcha/intro/index.html and click on Get reCAPTCHA at top of the page

Step 3: Modify your form to include reCaptcha

@using reCAPTCHA.MVC
@using (Html.BeginForm())
{
    @Html.Recaptcha()
    @Html.ValidationMessage("ReCaptcha")
    <input type="submit" value="Register" />
}

Step 4: Implement the Controller Action that will handle the form submission and Captcha validation

[CaptchaValidator(
PrivateKey = "your private reCaptcha Google Key",
ErrorMessage = "Invalid input captcha.",
RequiredMessage = "The captcha field is required.")]
public ActionResult MyAction(myVM model)
{
    if (ModelState.IsValid) //this will take care of captcha
    {
    }
}

OR

public ActionResult MyAction(myVM model, bool captchaValid)
{
    if (captchaValid) //manually check for captchaValid 
    {
    }
}

When workspace is damaged and Eclipse cannot start, even using the -clean option, removing single file workspace/.metadata/.plugins/org.eclipse.core.resources/.snap may help (source: comments to article https://web.archive.org/web/20200517003712/https://letsgetdugg.com/2009/04/19/recovering-a-corrupt-eclipse-workspace/).

Update: when Eclipse 4.X cannot start after crash, try to start with -clearPersistedState option; if it didn't help then remove file workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi (sources: https://www.eclipse.org/forums/index.php/m/1269045/ https://www.eclipse.org/forums/index.php/t/522428/ https://bugs.eclipse.org/bugs/show_bug.cgi?id=404873). Note: you'll lose configuration of your perspective/views/tabs.

Update: Subversive plugin may be responsible for inability to start Eclipse with corrupted metadata. If you have Subversive plugin installed, update it to latest build (at least 0.7.9.I20120210-1700) from update-site. Related bugs 372621 and 370374 were fixed by Subversive developers.

This seems to work just fine:

import sys
print sys._getframe().f_back.f_code.co_name

Apart from the impossibility to get file system access in JS, I would not put any trust at all in a client-generated checksum. So generating the checksum on the server is mandatory in any case. – Tomalak Apr 20 '09 at 14:05

Which is useless in most cases. You want the MD5 computed at client side, so that you can compare it with the code recomputed at server side and conclude the upload went wrong if they differ. I have needed to do that in applications working with large files of scientific data, where receiving uncorrupted files were key. My cases was simple, cause users had the MD5 already computed from their data analysis tools, so I just needed to ask it to them with a text field.

I recently ran into the same thing, and suggest this function for MSTest:

public bool AssertThrows(Action action) where T : Exception
{
    try {action();
}
catch(Exception exception)
{
    if (exception.GetType() == typeof(T))
        return true;
}
    return false;
}

Usage:

There is more in Assert that a particular exception has occured (Assert.Throws in MSTest).

JVM head dump is a snapshot of a JVM heap memory in a given time. So its simply a heap representation of JVM. That is the state of the objects.

JVM thread dump is a snapshot of a JVM threads at a given time. So thats what were threads doing at any given time. This is the state of threads. This helps understanding such as locked threads, hanged threads and running threads.

Head dump has more information of java class level information than a thread dump. For example Head dump is good to analyse JVM heap memory issues and OutOfMemoryError errors. JVM head dump is generated automatically when there is something like OutOfMemoryError has taken place. Heap dump can be created manually by killing the process using kill -3 . Generating a heap dump is a intensive computing task, which will probably hang your jvm. so itsn't a methond to use offetenly. Heap can be analysed using tools such as eclipse memory analyser.

Core dump is a os level memory usage of objects. It has more informaiton than a head dump. core dump is not created when we kill a process purposely.
