I'm using Phpass which is a simple one-file PHP class that could be implemented very easily in nearly every PHP project. See also The H.

By default it used strongest available encryption that is implemented in Phpass, which is bcrypt and falls back to other encryptions down to MD5 to provide backward compatibility to frameworks like Wordpress.

The returned hash could be stored in database as it is. Sample use for generating hash is:

$t_hasher = new PasswordHash(8, FALSE);
$hash = $t_hasher->HashPassword($password);

To verify password, one can use:

$t_hasher = new PasswordHash(8, FALSE);
$check = $t_hasher->CheckPassword($password, $hash);

In java8 IntSteam stream can be boxed to stream of Integers.

public static Iterable<Integer> toIterable(int[] ints) {
    return IntStream.of(ints).boxed().collect(Collectors.toList());
}

I think performance matters based on the size of the array.

I'm using the following configuration:

#site.yml:
- name: Example play
  hosts: all
  remote_user: ansible
  become: yes
  become_method: sudo
  vars:
    ansible_ssh_private_key_file: "/home/ansible/.ssh/id_rsa"

For an iBeacon with ProximityUUID E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, major 0, minor 0, and calibrated Tx Power of -59 RSSI, the transmitted BLE advertisement packet looks like this:

d6 be 89 8e 40 24 05 a2 17 6e 3d 71 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 52 ab 8d 38 a5

This packet can be broken down as follows:

d6 be 89 8e # Access address for advertising data (this is always the same fixed value)
40 # Advertising Channel PDU Header byte 0.  Contains: (type = 0), (tx add = 1), (rx add = 0)
24 # Advertising Channel PDU Header byte 1.  Contains:  (length = total bytes of the advertising payload + 6 bytes for the BLE mac address.)
05 a2 17 6e 3d 71 # Bluetooth Mac address (note this is a spoofed address)
02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 # Bluetooth advertisement
52 ab 8d 38 a5 # checksum

The key part of that packet is the Bluetooth Advertisement, which can be broken down like this:

02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010  
   bit 0 (OFF) LE Limited Discoverable Mode
   bit 1 (ON) LE General Discoverable Mode
   bit 2 (OFF) BR/EDR Not Supported
   bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
   bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)
1A # Number of bytes that follow in second (and last) AD structure
FF # Manufacturer specific data AD type
4C 00 # Company identifier code (0x004C == Apple)
02 # Byte 0 of iBeacon advertisement indicator
15 # Byte 1 of iBeacon advertisement indicator
e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 # iBeacon proximity uuid
00 00 # major 
00 00 # minor 
c5 # The 2's complement of the calibrated Tx Power

Any Bluetooth LE device that can be configured to send a specific advertisement can generate the above packet. I have configured a Linux computer using Bluez to send this advertisement, and iOS7 devices running Apple's AirLocate test code pick it up as an iBeacon with the fields specified above. See: Use BlueZ Stack As A Peripheral (Advertiser)

This blog has full details about the reverse engineering process.

I also had the error message "TypeError: cannot concatenate 'str' and 'int' objects". It turns out that I only just forgot to add str() around a variable when printing it. Here is my code:

def main():_x000D_
 rolling = True; import random_x000D_
 while rolling:_x000D_
  roll = input("ENTER = roll; Q = quit ")_x000D_
  if roll.lower() != 'q':_x000D_
   num = (random.randint(1,6))_x000D_
   print("----------------------"); print("you rolled " + str(num))_x000D_
  else:_x000D_
   rolling = False_x000D_
main()

I know, it was a stupid mistake but for beginners who are very new to python such as myself, it happens.

In the root web.config for your project, under the system.web node:

<system.web>
    <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" />

If you are looking for tools like the the mysql and mysqldump command line client for Windows for versions around mysql Ver 14.14 Distrib 5.6.13, for Win32 (x86) it seems to be in HOMEDRIVE:\Program Files (x86)\MySQL\MySQL Workbench version

This directory is also not placed in the path by default so you will need to add it to your PATH environment variable before you can easily run it from the command prompt.

Also, there is a mysql utilities console but it does not work for my needs. Below is a list of the capabilities on the mysql utilities console in case it works for you:

Utility           Description
----------------  ---------------------------------------------------------
mysqlauditadmin   audit log maintenance utility
mysqlauditgrep    audit log search utility
mysqldbcompare    compare databases for consistency
mysqldbcopy       copy databases from one server to another
mysqldbexport     export metadata and data from databases
mysqldbimport     import metadata and data from files
mysqldiff         compare object definitions among objects where the
                  difference is how db1.obj1 differs from db2.obj2

mysqlrplshow      show slaves attached to a master
mysqlserverclone  start another instance of a running server
mysqlserverinfo   show server information
mysqluserclone    clone a MySQL user account to one or more new users

You can just do that too, it seems to work well too. sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"

You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.

You could look at the Wikipedia article on Standard Deviation, in particular the section about Rapid calculation methods.

There's also an article I found that uses Python, you should be able to use the code in it without much change: Subliminal Messages - Running Standard Deviations.

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector

You did not assign the "linux" to the question but you mentioned "Linux top". And thus this might be helpful:

Use the small Linux tool threadcpu to identify the most cpu using threads. It calls jstack to get the thread name. And with "sort -n" in pipe you get the list of threads ordered by cpu usage.

More details can be found here: http://www.tuxad.com/blog/archives/2018/10/01/threadcpu_-_show_cpu_usage_of_threads/index.html

And if you still need more details then create a thread dump or run strace on the thread.

Avro is a row-based storage format for Hadoop.

Parquet is a column-based storage format for Hadoop.

If your use case typically scans or retrieves all of the fields in a row in each query, Avro is usually the best choice.

If your dataset has many columns, and your use case typically involves working with a subset of those columns rather than entire records, Parquet is optimized for that kind of work.

Adding to Dmitri Chebotarev's answer, as for Laravel 5+.

After requiring the doctrine/dbal package:

composer require doctrine/dbal

You can then make a migration with nullable columns, like so:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

To revert the operation, do:

public function down()
{
    /* turn off foreign key checks for a moment */
    DB::statement('SET FOREIGN_KEY_CHECKS = 0');
    /* set null values to 0 first */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    /* alter table */
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
    /* finally turn foreign key checks back on */
    DB::statement('SET FOREIGN_KEY_CHECKS = 1');
}

Like this:

if ($('input[value=""]').length > 0) {
   console.log('some fields are empty!')
}

You've started right - now you just need to fill the each student structure in the array:

struct student
{
    public int s_id;
    public String s_name, c_name, dob;
}
class Program
{
    static void Main(string[] args)
    {
        student[] arr = new student[4];

        for(int i = 0; i < 4; i++)
        {
            Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");


            arr[i].s_id = Int32.Parse(Console.ReadLine());
            arr[i].s_name = Console.ReadLine();
            arr[i].c_name = Console.ReadLine();
            arr[i].s_dob = Console.ReadLine();
       }
    }
}

Now, just iterate once again and write these information to the console. I will let you do that, and I will let you try to make program to take any number of students, and not just 4.

C# CLI is a very simple command-line argument parsing library that I wrote. It's well-documented and open source.

I use if (this.variable) to test if it is defined. A simple if (variable), recommended in a previous answer, fails for me.

It turns out that it works only when a variable is a field of some object, obj.someField to check if it is defined in the dictionary. But we can use this or window as the dictionary object since any variable is a field in the current window, as I understand it. Therefore here is a test:

if (this.abc) 
    alert("defined"); 
else 
    alert("undefined");

abc = "abc";
if (this.abc) 
    alert("defined"); 
else 
    alert("undefined");

It first detects that variable abc is undefined and it is defined after initialization.

If you use the runtime/totalMemory solution that has been posted in many answers here (I've done that a lot), be sure to force two garbage collections first if you want fairly accurate/consistent results.

For effiency Java usually allows garbage to fill up all of memory before forcing a GC, and even then it's not usually a complete GC, so your results for runtime.freeMemory() always be somewhere between the "real" amount of free memory and 0.

The first GC doesn't get everything, it gets most of it.

The upswing is that if you just do the freeMemory() call you will get a number that is absolutely useless and varies widely, but if do 2 gc's first it is a very reliable gauge. It also makes the routine MUCH slower (seconds, possibly).

You cannot run it on main thread instead use handlers, async or working threads . A sample code is available here and read article over room library here : Android's Room Library

/**
 *  Insert and get data using Database Async way
 */
AsyncTask.execute(new Runnable() {
    @Override
    public void run() {
        // Insert Data
        AppDatabase.getInstance(context).userDao().insert(new User(1,"James","Mathew"));

        // Get Data
        AppDatabase.getInstance(context).userDao().getAllUsers();
    }
});

If you want to run it on main thread which is not preferred way .

You can use this method to achieve on main thread Room.inMemoryDatabaseBuilder()

The parentheses are poorly placed.

You need to use:

doThrow(new Exception()).when(mockedObject).methodReturningVoid(...);
                                          ^

and NOT use:

doThrow(new Exception()).when(mockedObject.methodReturningVoid(...));
                                                                   ^

This is explained in the documentation

Situation:

• You have local uncommitted changes
• You pull from the master repo
• You get the error "Checkout conflict with files: xy"

Solution:

• Stage and commit (at least) the files xy
• Pull again
• If automerge is possible, everything is ok.
• If not, the pull merges the files and inserts the merge-conflict markers (<<<<<<, >>>>)
  • Manually edit the conflicting files
• Commit and push

This work for me:

Login as root:

mysql -u root -p

and then you deactivate the automatic expiration of passwords of all the users:

SET GLOBAL default_password_lifetime = 0;

There is a new feature in Directory and DirectoryInfo in .NET 4 that allows them to return an IEnumerable instead of an array, and start returning results before reading all the directory contents.

• What's New in the BCL in .NET 4 Beta 1
• Directory.EnumerateFileSystemEntries method overloads

public bool IsDirectoryEmpty(string path)
{
    IEnumerable<string> items = Directory.EnumerateFileSystemEntries(path);
    using (IEnumerator<string> en = items.GetEnumerator())
    {
        return !en.MoveNext();
    }
}

EDIT: seeing that answer again, I realize this code can be made much simpler...

public bool IsDirectoryEmpty(string path)
{
    return !Directory.EnumerateFileSystemEntries(path).Any();
}

http://devcenter.heroku.com/articles/maintenance-mode

If you’re deploying a large migration or need to disable access to your application for some length of time, you can use Heroku’s built in maintenance mode. It will serve a static page to all visitors, while still allowing you to run rake tasks or console commands.

$ heroku maintenance:on
Maintenance mode enabled.

and later

$ heroku maintenance:off
Maintenance mode disabled.

I've found this page on their github repo, I'll just paste the content here.

Recommended approach for saving a model

There are two main approaches for serializing and restoring a model.

The first (recommended) saves and loads only the model parameters:

torch.save(the_model.state_dict(), PATH)

Then later:

the_model = TheModelClass(*args, **kwargs)
the_model.load_state_dict(torch.load(PATH))

The second saves and loads the entire model:

torch.save(the_model, PATH)

Then later:

the_model = torch.load(PATH)

However in this case, the serialized data is bound to the specific classes and the exact directory structure used, so it can break in various ways when used in other projects, or after some serious refactors.

In my case, I was missing a "name" attribute on my input element.

You should also look at new triggers.

MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:

use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;

delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row 
begin 
  insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//

/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');

print("Name={}, balance={}".format(var-name, var-balance))

Add this line to CardView....

card_view:cardUseCompatPadding="true" //for enable shadow
card_view:cardElevation="9dp" // this for how much shadow you want to show

Tips

You can avoid layout_marginTop and layout_marginBottom as shadow itself takes some space to the up and down of it.The amount space defined by how much you will use in card_view:cardElevation="ndp" .

This is an old question, but, as a newbie I figured I'd add that (using Webstorm) you need to click on Mongo Explorer (tab on far right hand side of your window). From there:

-Click settings. -Click browse button (looks like a button with "..." on it). -Go to Program Files > MongoDB > Server > 3.4 > bin > mongo.exe (your version maybe different than 3.4) -After that, click the green plus sign on the right. A window will open -Enter a name in "Label" slot. -Click apply.

You should now be connected. Entering "mongod" in the terminal isn't enough. You have to do the above steps also.

My apologies in advance to those of you who aren't using Webstorm! Not sure about the steps using other IDE's.

Neither of the above answers worked for me, however this did

UPDATE:

As @doppleganger pointed out below, load is gone as of jQuery 3.0, so here's an updated version that uses on. Please note this will actually work on jQuery 1.7+, so you can implement it this way even if you're not on jQuery 3.0 yet.

$('iframe').on('load', function() {
    // do stuff 
});

You can also add linker flags to a specific target using the LINK_FLAGS property:

set_property(TARGET ${target} APPEND_STRING PROPERTY LINK_FLAGS " ${flag}")

If you want to propagate this change to other targets, you can create a dummy target to link to.

to work this with unicode or fontawesome, you should add a span with class like below, because input tag not support pseudo classes like :after. this is not a direct solution

in html:

   <span class="button1 search"></span>
<input name="username">

in css:

.button1 {
    background-color: #B9D5AD;
    border-radius: 0.2em 0 0 0.2em;
    box-shadow: 1px 0 0 rgba(0, 0, 0, 0.5), 2px 0 0 rgba(255, 255, 255, 0.5); 
    pointer-events: none;
    margin:1px 12px;    
    border-radius: 0.2em;    
    color: #333333;
    cursor: pointer;
    position: absolute;
    padding: 3px;
    text-decoration: none;   

}

Try IndexOf.

None of these work?

Was getting Illegal mix of collations while creating a category in Bagisto. Running these commands (thank you @Quy Le) solved the issue for me:

--set utf8 for connection

SET collation_connection = 'utf8_general_ci'

--change CHARACTER SET of DB to utf8

ALTER DATABASE dbName CHARACTER SET utf8 COLLATE utf8_general_ci

--change category tables

ALTER TABLE categories CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci

ALTER TABLE category_translations CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci

If you don't care about the type of the numbers you can simply use:

qs[0].values()

The best and easy way to get the activity context is putting .this after the name of the Activity. For example: If your Activity's name is SecondActivity, its context will be SecondActivity.this

(As of June 10, 2020)

Swift 5 (Without editing .Plist file)

If you are using Storyboard, go to the NavigationController, select the navigationBar, click on the Attributes Inspector, then change the style. if you need light content (white status bar) set it anything except default lets say set style black And if you want dark content (black status bar) set it default.

The default (UIBarStyleDefault) results in the dark foreground UIStatusBarStyleDefault status bar. And UIBarStyleBlack will give a UIStatusBarStyleLightContent status bar.

Programatically

let nav = UINavigationController(rootViewController: rootViewController)

    nav.navigationBar.barStyle = .default //gives you dark Content status bar

    nav.navigationBar.barStyle = .black  //gives you light content status bar

Without Navigation Bar (Edit .Plist)

add UIViewControllerBasedStatusBarAppearance / View controller-based status bar appearance to your info.plist, and set value is true.

Override the preferredStatusBarStyle property in your Controller

class ViewController: UIViewController {
    override var preferredStatusBarStyle : UIStatusBarStyle {
        return .lightContent
    }
}

Set your css in the table cell to

white-space:pre-wrap;

document.body.innerHTML = 'First line\nSecond line\nThird line';

body{ white-space:pre-wrap; }

EDIT :

According to the ItemAnimator documentation :

This class defines the animations that take place on items as changes are made to the adapter.

So unless you add your items one by one to your RecyclerView and refresh the view at each iteration, I don't think ItemAnimator is the solution to your need.

Here is how you can animate the RecyclerView items when they appear using a CustomAdapter :

public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder>
{
    private Context context;

    // The items to display in your RecyclerView
    private ArrayList<String> items;
    // Allows to remember the last item shown on screen
    private int lastPosition = -1;

    public static class ViewHolder extends RecyclerView.ViewHolder
    {
        TextView text;
        // You need to retrieve the container (ie the root ViewGroup from your custom_item_layout)
        // It's the view that will be animated
        FrameLayout container;

        public ViewHolder(View itemView)
        {
            super(itemView);
            container = (FrameLayout) itemView.findViewById(R.id.item_layout_container);
            text = (TextView) itemView.findViewById(R.id.item_layout_text);
        }
    }

    public CustomAdapter(ArrayList<String> items, Context context)
    {
        this.items = items;
        this.context = context;
    }

    @Override
    public CustomAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_item_layout, parent, false);
        return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position)
    {
        holder.text.setText(items.get(position));

        // Here you apply the animation when the view is bound
        setAnimation(holder.itemView, position);
    }

    /**
     * Here is the key method to apply the animation
     */
    private void setAnimation(View viewToAnimate, int position)
    {
        // If the bound view wasn't previously displayed on screen, it's animated
        if (position > lastPosition)
        {
            Animation animation = AnimationUtils.loadAnimation(context, android.R.anim.slide_in_left);
            viewToAnimate.startAnimation(animation);
            lastPosition = position;
        }
    }
}

And your custom_item_layout would look like this :

<FrameLayout
    android:id="@+id/item_layout_container"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/item_layout_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceListItemSmall"
        android:gravity="center_vertical"
        android:minHeight="?android:attr/listPreferredItemHeightSmall"/>

</FrameLayout>

For more information about CustomAdapters and RecyclerView, refer to this training on the official documentation.

Problems on fast scroll

Using this method could cause problems with fast scrolling. The view could be reused while the animation is been happening. In order to avoid that is recommendable to clear the animation when is detached.

    @Override
    public void onViewDetachedFromWindow(final RecyclerView.ViewHolder holder)
    {
        ((CustomViewHolder)holder).clearAnimation();
    }

On CustomViewHolder:

    public void clearAnimation()
    {
        mRootLayout.clearAnimation();
    }

Old answer :

Give a look at Gabriele Mariotti's repo, I'm pretty sure you'll find what you need. He provides simple ItemAnimators for the RecyclerView, such as SlideInItemAnimator or SlideScaleItemAnimator.

You can use -webkit-border-radius: 0;. Like this:-

-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;

This will give square corners as well as dropdown arrows. Using -webkit-appearance: none; is not recommended as it will turn off all the styling done by Chrome.

There's a way to do it from GitHub's webapp.

Let's go through the following example.

To start with, open the repo that you want to update.

One can see the warning

This branch is 157 commits behind GoogleCloudPlatform:master.

On the right there are two buttons Pull request and Compare. Press Compare.

As there is probably nothing to compare, press switching the base

A list of all the changes will appear and one can create a pull request by pressing the button Create pull request

Give it a title, let's say "Update repo"

And create the pull request.

one can print values using the format method in python. This small example will help take input of two numbers a and b. Print a+b in first line and a-b in second line

print('{:d}\n{:d}'.format(a+b,a-b))

Similarly in the answer we can do

print ("{0}. {1} appears {2} times.".format(22, 'c', 9999))

The python method format() for string is used to specify a string format. So {0},{1},{2} are like array indexes called as positional parameters. Therefore {0} is assigned first value written in format (a+b), {1} is assigned the second value (a-b) and so on. We can also use keyword instead of positional parameter like for example

print("Hi! my name is {name}".format(name="rashi"))

Therefore name here is the keyword and its value is Rashi Hope it helps :)

Found a site on google explaining some changes, according to the author of the page fb does not allow custom buttons. Heres the website.

Unfortunately, it’s against Facebook’s developer policies, which state:

You must not circumvent our intended limitations on core Facebook features.

The Facebook Connect button is intended to be rendered in FBML, which means it’s only meant to look the way Facebook lets it.

My answer may seem a bit too late, but i happened to come across this same error in Android Studio after upgrading the SDK to API 21. I tried all the solutions i came across here on this site and https://code.google.com/p/android/issues/detail?id=61308. Here's how i eventually resoled this error: I opened the app's gradle.build file and changed it from this:

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.0"

    defaultConfig {
        applicationId "com.abundantideas.layoutsample"
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }

to that:

android {
    compileSdkVersion 21
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.abundantideas.layoutsample"
        minSdkVersion 8
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }

I lowered the buildToolsVersion and the targetSdkVersion values back to 20 which i knew was working fine before the upgrade. It looks like API 21 was causing problems for Gradle, in my case. I hope this will help others too.

Here is a code I am using and which is working for me.

window.onload = function(){
    setTimeout(function(){
        var scriptElement=document.createElement('script');
        scriptElement.type = 'text/javascript';
        scriptElement.src = "vendor/js/jquery.min.js";
        document.head.appendChild(scriptElement);

        setTimeout(function() {
            var scriptElement1=document.createElement('script');
            scriptElement1.type = 'text/javascript';
            scriptElement1.src = "gallery/js/lc_lightbox.lite.min.js";
            document.head.appendChild(scriptElement1);
        }, 100);
        setTimeout(function() {
            $(document).ready(function(e){
                lc_lightbox('.elem', {
                    wrap_class: 'lcl_fade_oc',
                    gallery : true, 
                    thumb_attr: 'data-lcl-thumb', 
                    slideshow_time  : 3000,
                    skin: 'minimal',
                    radius: 0,
                    padding : 0,
                    border_w: 0,
                }); 
            });
        }, 200);

    }, 150);
};

Please see my answer here. As dreamwerx.myopenid.com points out, it is possible to do this with SimpleXML, but the DOM extension would be the better and more flexible way. Additionally there is a third way: using XMLWriter. It's much more simple to use than the DOM and therefore it's my preferred way of writing XML documents from scratch.

$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
    $w->writeAttribute("ah", "OK");
    $w->text('Wow, it works!');
$w->endElement();
echo htmlentities($w->outputMemory(true));

By the way: DOM stands for Document Object Model; this is the standardized API into XML documents.

A bearer token is like a currency note e.g 100$ bill . One can use the currency note without being asked any/many questions.

Bearer Token A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

Using CentOS7, logs are available using the command journalctl -u docker. Answering distinctly, because @sabin's answer might be accurate for older versions of CentOS but was not true for me.

I'm pretty sure this is a bug in Chrome. Most likely it happens if you resize the browser TO full screen, then switch tabs. And sometimes if you just switch tabs/open a new one. Good to hear you found a "fix" though.

Try this:

df.loc[len(df)]=['8/19/2014','Jun','Fly','98765'] 

Warning: this method works only if there are no "holes" in the index. For example, suppose you have a dataframe with three rows, with indices 0, 1, and 3 (for example, because you deleted row number 2). Then, len(df) = 3, so by the above command does not add a new row - it overrides row number 3.

}

Editing to add:

Both David's answer using any and mine using in will end when they find a match since we're using generator expressions. Here is a test using an infinite generator to show that:

def mygen():
    ''' Infinite generator '''
    while True:
        yield 'xxx'  # Just to include a non-match in the generator
        yield 'd'

print 'd' in (x for x in mygen())     # True
print any('d' == x for x in mygen())  # True
# print 'q' in (x for x in mygen())     # Never ends if uncommented
# print any('q' == x for x in mygen())  # Never ends if uncommented

I just like simply using in instead of both == and any.

Most of the solutions are directly using grep command to find the class. However, it would not give you the package name of the class. Also if the jar is compressed, grep will not work.

This solution is using jar command to list the contents of the file and grep the class you are looking for.

It will print out the class with package name and also the jar file name.

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep Hello.class &&  echo {}'

You can also search with your package name like below:

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep com/mypackage/Hello.class &&  echo {}'

Maybe you mean like this? I like to make an object and use Format-Table:

> $array = @()
> $object = New-Object -TypeName PSObject
> $object | Add-Member -Name 'Name' -MemberType Noteproperty -Value 'Joe'
> $object | Add-Member -Name 'Age' -MemberType Noteproperty -Value 32
> $object | Add-Member -Name 'Info' -MemberType Noteproperty -Value 'something about him'
> $array += $object
> $array | Format-Table

Name                                                                        Age Info
----                                                                        --- ----
Joe                                                                          32  something about him

This will put all objects you have in the array in columns according to their properties.

Tip: Using -auto sizes the table better

> $array | Format-Table -Auto

Name Age Info
---- --- ----
Joe   32 something about him

You can also specify which properties you want in the table. Just separate each property name with a comma:

> $array | Format-Table Name, Age -Auto

Name Age
---- ---
Joe   32

What you are looking for is Dynamic Programming.

You don't actually have to enumerate all the possible combinations for every possible values, because you can build it on top of previous answers.

You algorithm need to take 2 parameters:

• The list of possible coin values, here [1, 5, 10, 25]
• The range to cover, here [1, 99]

And the goal is to compute the minimal set of coins required for this range.

The simplest way is to proceed in a bottom-up fashion:

Range     Number of coins (in the minimal set)
          1   5   10   25
[1,1]     1
[1,2]     2
[1,3]     3
[1,4]     4
[1,5]     5
[1,5]*    4   1             * two solutions here
[1,6]     4   1
[1,9]     4   1
[1,10]    5   1             * experience tells us it's not the most viable one :p
[1,10]    4   2             * not so viable either
[1,10]    4   1   1
[1,11]    4   1   1
[1,19]    4   1   1
[1,20]    5   1   1         * not viable (in the long run)
[1,20]    4   2   1         * not viable (in the long run)
[1,20]    4   1   2

It is somewhat easy, at each step we can proceed by adding at most one coin, we just need to know where. This boils down to the fact that the range [x,y] is included in [x,y+1] thus the minimal set for [x,y+1] should include the minimal set for [x,y].

As you may have noticed though, sometimes there are indecisions, ie multiple sets have the same number of coins. In this case, it can only be decided later on which one should be discarded.

It should be possible to improve its running time, when noticing that adding a coin usually allows you to cover a far greater range that the one you added it for, I think.

For example, note that:

 [1,5]    4*1  1*5
 [1,9]    4*1  1*5

we add a nickel to cover [1,5] but this gives us up to [1,9] for free!

However, when dealing with outrageous input sets [2,3,5,10,25] to cover [2,99], I am unsure as how to check quickly the range covered by the new set, or it would be actually more efficient.

This would be better approach as I have implemented :)

@model ObjectUser
@using System.Web.Script.Serialization
@{ 
    var javaScriptSearilizer = new JavaScriptSerializer();
    var searializedObject = javaScriptSearilizer.Serialize(Model);
 }

<script>
    var searializedObject = @Html.Raw(searializedObject )
    console.log(searializedObject);
    alert(searializedObject);
</script>

Hope this will help you to prevent you from iterating model ( happy coding )

when I load in a json object I usually setup the relationships by iterating through the object arrays like this:

    for (var i = 0; i < some.json.objectarray.length; i++) {
        var p = some.json.objectarray[i];
        for (var j = 0; j < p.somechildarray.length; j++) {
            p.somechildarray[j].parent = p;
        }
    }

then you can access the parent object of some object in the somechildarray by using .parent

While plain old JavaScript objects can be used as maps, they are usually implemented in a way to preserve insertion-order for compatibility with most browsers (see Craig Barnes's answer) and are thus not simple hash maps.

ES6 introduces proper Maps (see MDN JavaScript Map) of which the standard says:

Map object must be implemented using either hash tables or other mechanisms that, on average, provide access times that are sublinear on the number of elements in the collection.

check

System.getProperty("sun.jnu.encoding")

it seems to be the same encoding as the one used in your system's command line.

You can use instanceof.

JLS 15.20.2 Type Comparison Operator instanceof

 RelationalExpression:
    RelationalExpression instanceof ReferenceType

At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.

That means you can do something like this:

Object o = new int[] { 1,2 };
System.out.println(o instanceof int[]); // prints "true"        

You'd have to check if the object is an instanceof boolean[], byte[], short[], char[], int[], long[], float[], double[], or Object[], if you want to detect all array types.

Also, an int[][] is an instanceof Object[], so depending on how you want to handle nested arrays, it can get complicated.

For the toString, java.util.Arrays has a toString(int[]) and other overloads you can use. It also has deepToString(Object[]) for nested arrays.

public String toString(Object arr) {
   if (arr instanceof int[]) {
      return Arrays.toString((int[]) arr);
   } else //...
}

It's going to be very repetitive (but even java.util.Arrays is very repetitive), but that's the way it is in Java with arrays.

See also

• Managing highly repetitive code and documentation in Java
• Java Arrays.equals() returns false for two dimensional arrays.

I see that some solutions have been provided but not any causes so I will explain this in detail as I believe it is as important to know what were you doing wrong that just to get "something" that works from the given replies.

First, let's see what Oracle has to say

 * <p>The returned array will be "safe" in that no references to it are
 * maintained by this list.  (In other words, this method must
 * allocate a new array even if this list is backed by an array).
 * The caller is thus free to modify the returned array.

It may not look important but as you'll see it is... So what does the following line fail? All object in the list are String but it does not convert them, why?

List<String> tList = new ArrayList<String>();
tList.add("4");
tList.add("5");
String tArray[] = (String[]) tList.toArray();   

Probably, many of you would think that this code is doing the same, but it does not.

Object tSObjectArray[] = new String[2];
String tStringArray[] = (String[]) tSObjectArray;

When in reality the written code is doing something like this. The javadoc is saying it! It will instatiate a new array, what it will be of Objects!!!

Object tSObjectArray[] = new Object[2];
String tStringArray[] = (String[]) tSObjectArray;   

So tList.toArray is instantiating a Objects and not Strings...

Therefore, the natural solution that has not been mentioning in this thread, but it is what Oracle recommends is the following

String tArray[] = tList.toArray(new String[0]);

Hope it is clear enough.

You can achieve this with the following code:

$("input").change(function(e) {

    for (var i = 0; i < e.originalEvent.srcElement.files.length; i++) {

        var file = e.originalEvent.srcElement.files[i];

        var img = document.createElement("img");
        var reader = new FileReader();
        reader.onloadend = function() {
             img.src = reader.result;
        }
        reader.readAsDataURL(file);
        $("input").after(img);
    }
});

Seems you are using outdated version of django.. Simply update django and try again.. Following command will update your django version..

pip install --upgrade django

It's help me :

  var key = 'Hallo';

   if ( $("#chosen_b option[value='"+key+"']").length == 0 ){
   alert("option not exist!");

    $('#chosen_b').append("<option value='"+key+"'>"+key+"</option>");
    $('#chosen_b').val(key);
   $('#chosen_b').trigger("chosen:updated");
                         }
  });

Anyone else who is struggling with this, there is a very simple "inline" way to do this with jQuery:

<input type="search" placeholder="Search" value="" maxlength="256" id="q" name="q" style="width: 300px;" onChange="$('#ADSearch').attr('value', $('#q').attr('value'))"><input type="hidden" name="ADSearch" id="ADSearch" value="">

This sets the value of the hidden field as text is typed into the visible input using the onChange event. Helpful (like in my case) where you want to pass on a field value to an "Advanced Search" form and not force the user to re-type their search query.

Try this one:

$(document).ready(function() {
    $(".tab").click(function () {
        $("this").addClass("active").siblings().removeClass("active");   
    });
});

The only thing that helped is to use a file of JSON instead of json body text. Based on How to send file contents as body entity using cURL

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

I had to add the following i386 and x86_64 to Valid Architectures. I'm running Xcode 7.2 and targeting iOS 8+. I already had armv7, armv7s and arm64 in there and that was working in Xcode 6.4.

If you're really just annoyed at using try/excepts all over the place, please just write a helper function:

def RepresentsInt(s):
    try: 
        int(s)
        return True
    except ValueError:
        return False

>>> print RepresentsInt("+123")
True
>>> print RepresentsInt("10.0")
False

It's going to be WAY more code to exactly cover all the strings that Python considers integers. I say just be pythonic on this one.

LTRIM(RTRIM(FCT_TYP_CD)) & ') AND (' & LTRIM(RTRIM(DEP_TYP_ID)) & ')'

I think you're missing a ) on both of the trims. Some SQL versions support just TRIM which does both L and R trims...

The other answer below by Eric is wrong. The namespace declaration he mentioned had nothing to do with the problem.

The real reason it doesn't work is due to security concerns (cf. issue 4197, issue 111905).

Imagine this scenario:

1. You receive an email message from an attacker containing a web page as an attachment, which you download.

2. You open the now-local web page in your browser.

3. The local web page creates an <iframe> whose source is https://mail.google.com/mail/.

4. Because you are logged in to Gmail, the frame loads the messages in your inbox.

5. The local web page reads the contents of the frame by using JavaScript to access frames[0].document.documentElement.innerHTML. (An online web page would not be able to perform this step because it would come from a non-Gmail origin; the same-origin policy would cause the read to fail.)

6. The local web page places the contents of your inbox into a <textarea> and submits the data via a form POST to the attacker's web server. Now the attacker has your inbox, which may be useful for spamming or identify theft.

Chrome foils the above scenario by putting restrictions on local files opened using Chrome. To overcome these restrictions, we've got two solutions:

1. Try running Chrome with the --allow-file-access-from-files flag. I've not tested this myself, but if it works, your system will now also be vulnerable to scenarios of the kind mentioned above.

2. Upload it to a host, and problem solved.

Bootstrap 5

In Bootstrap 5 (alpha) there is a new -xxl- size:

col-* - 0 (xs)
col-sm-* - 576px
col-md-* - 768px
col-lg-* - 992px
col-xl-* - 1200px
col-xxl-* - 1400px

Bootstrap 5 Grid Demo

Bootstrap 4

In Bootstrap 4 there is a new -xl- size, see this demo. Also the -xs- infix has been removed, so smallest columns are simply col-1, col-2.. col-12, etc..

col-* - 0 (xs)
col-sm-* - 576px
col-md-* - 768px
col-lg-* - 992px
col-xl-* - 1200px

Bootstrap 4 Grid Demo

Additionally, Bootstrap 4 includes new auto-layout columns. These also have responsive breakpoints (col, col-sm, col-md, etc..), but don't have defined % widths. Therefore, the auto-layout columns fill equal width across the row.

Bootstrap 3

The Bootstrap 3 grid comes in 4 tiers (or "breakpoints")...

• Extra small (for smartphones .col-xs-*)
• Small (for tablets .col-sm-*)
• Medium (for laptops .col-md-*)
• Large (for laptops/desktops .col-lg-*).

These grid sizes enable you to control grid behavior on different widths. The different tiers are controlled by CSS media queries.

So in Bootstrap's 12-column grid...

col-sm-3 is 3 of 12 columns wide (25%) on a typical small device width (> 768 pixels)

col-md-3 is 3 of 12 columns wide (25%) on a typical medium device width (> 992 pixels)

The smaller tier (xs, sm or md) also defines the size for larger screen widths. So, for the same size column on all tiers, just set the width for the smallest viewport...

<div class="col-lg-3 col-md-3 col-sm-3">..</div> is the same as,

<div class="col-sm-3">..</div>

Larger tiers are implied. Because col-sm-3 means 3 units on sm-and-up, unless specifically overridden by a larger tier that uses a different size.

xs(default) > overridden by sm > overridden by md > overridden by lg

Combine the classes to use change column widths on different grid sizes. This creates a responsive layout.

<div class="col-md-3 col-sm-6">..</div>

The sm, md and lg grids will all "stack" vertically on screens/viewports less than 768 pixels. This is where the xs grid fits in. Columns that use the col-xs-* classes will not stack vertically, and continue to scale down on the smallest screens.

Resize your browser using this demo and you'll see the grid scaling effects.

This article explains more about how the Bootstrap grid

If you're OK with not using <p>s (only <div>s and <span>s), this solution might even allow you to align your inline-blocks center or right, if you want to (or just keep them left, the way you originally asked for). While the solution might still work with <p>s, I don't think the resulting HTML code would be quite correct, but it's up to you anyways.

The trick is to wrap each one of your <span>s with a corresponding <div>. This way we're taking advantage of the line break caused by the <div>'s display: block (default), while still keeping the visual green box tight to the limits of the text (with your display: inline-block declaration).

.text span {_x000D_
   background:rgba(165, 220, 79, 0.8);_x000D_
   display:inline-block;_x000D_

I had the similar issue and the above examples doesn't help me to read properties. I have posted the complete class which will help you to read properties values from application.properties file in SpringBoot application in the below link.

Spring Boot - Environment @Autowired throws NullPointerException

ALTER TABLE your_table
ADD PRIMARY KEY (Drugid);

I add common parts as header and footer using Server Side Includes. No HTML and no JavaScript is needed. Instead, the webserver automatically adds the included code before doing anything else.

Just add the following line where you want to include your file:

<!--#include file="include_head.html" -->

You must use %ld to print a long int, and %lld to print a long long int.

Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you're using).

You will also need to ensure that you use your compiler in a C99-compatible mode (for example, using the -std=gnu99 option to gcc). This is because the long long int type was not introduced until C99; and although many compilers implement long long int in C90 mode as an extension, the constant 2147483648 may have a type of unsigned int or unsigned long in C90. If this is the case in your implementation, then the value of -2147483648 will also have unsigned type and will therefore be positive, and the overall result will be not what you expect.

As a twist of the accepted answer (https://stackoverflow.com/a/255638/986160) assuming that the keys will be associated with signle values in the dictionary. Similar to (https://stackoverflow.com/a/255630/986160) but a bit more elegant. The novelty is in that the consuming class can be used as an enumeration alternative (but for strings too) and that the dictionary implements IEnumerable.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;

namespace MyApp.Dictionaries
{

    class BiDictionary<TFirst, TSecond> : IEnumerable
    {
        IDictionary<TFirst, TSecond> firstToSecond = new Dictionary<TFirst, TSecond>();
        IDictionary<TSecond, TFirst> secondToFirst = new Dictionary<TSecond, TFirst>();

        public void Add(TFirst first, TSecond second)
        {
            firstToSecond.Add(first, second);
            secondToFirst.Add(second, first);
        }

        public TSecond this[TFirst first]
        {
            get { return GetByFirst(first); }
        }

        public TFirst this[TSecond second]
        {
            get { return GetBySecond(second); }
        }

        public TSecond GetByFirst(TFirst first)
        {
            return firstToSecond[first];
        }

        public TFirst GetBySecond(TSecond second)
        {
            return secondToFirst[second];
        }

        public IEnumerator GetEnumerator()
        {
            return GetFirstEnumerator();
        }

        public IEnumerator GetFirstEnumerator()
        {
            return firstToSecond.GetEnumerator();
        }

        public IEnumerator GetSecondEnumerator()
        {
            return secondToFirst.GetEnumerator();
        }
    }
}

And as a consuming class you could have

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MyApp.Dictionaries
{
    class Greek
    {

        public static readonly string Alpha = "Alpha";
        public static readonly string Beta = "Beta";
        public static readonly string Gamma = "Gamma";
        public static readonly string Delta = "Delta";


        private static readonly BiDictionary<int, string> Dictionary = new BiDictionary<int, string>();


        static Greek() {
            Dictionary.Add(1, Alpha);
            Dictionary.Add(2, Beta);
            Dictionary.Add(3, Gamma);
            Dictionary.Add(4, Delta);
        }

        public static string getById(int id){
            return Dictionary.GetByFirst(id);
        }

        public static int getByValue(string value)
        {
            return Dictionary.GetBySecond(value);
        }

    }
}

What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm-vs-fcgi but more to the implementation of your httpd).

For example, I had a quad-core machine running lighttpd + fcgi humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd every 30 minutes to keep the website up.

I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.

Is this due to php-fpm being better than fcgi? Not entirely, but how you hook into php-fpm seems to be a whole heckuva lot more efficient than how you serve via fcgi.

SIMPLE SOLUTION (tested on Red Hat):

run command: curl -sS https://getcomposer.org/installer | php

to use it: php composer.phar

SYSTEM WIDE SOLLUTION (tested on Red Hat):

run command: mv composer.phar /usr/local/bin/composer

to use it: composer update

now you can call composer from any directory.

I got the answer for the same , Go on SQL Server ? Tools ? Options ? Designers ? Table and Database Designers and unselect Prevent saving changes that require table re-creation

2- Open table design view and that scroll your column up and down and save your changes.

It's used to add padding in UIScrollView

Without contentInset, a table view is like this:

Then set contentInset:

tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

The effect is as below:

Seems to be better, right?

And I write a blog to study the contentInset, criticism is welcome.

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

You can null/blank/space Etc value using LinQ Use Following Query

   var BlankValueRows = (from dr1 in Dt.AsEnumerable()
                                  where dr1["Columnname"].ToString() == ""
                                  || dr1["Columnname"].ToString() == ""
                                   || dr1["Columnname"].ToString() == ""
                                  select Columnname);

Here Replace Columnname with table column name and "" your search item in above code we looking null value.

Use import scala.collection.mutable.MutableList or similar if you really need mutation.

import scala.collection.mutable.MutableList
val x = MutableList(1, 2, 3, 4, 5)
x += 6 // MutableList(1, 2, 3, 4, 5, 6)
x ++= MutableList(7, 8, 9) // MutableList(1, 2, 3, 4, 5, 6, 7, 8, 9)

A more simple way I came across while searching for this answer as well;

string date = DateTime.Now.ToString("yyyyMMdd", System.Globalization.CultureInfo.GetCultureInfo("en-US"));

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

I prefer to install the PowerShell Community Extensions and just use the Get-FileVersionInfo function that it provides.

Like so:

Get-FileVersionInfo MyAssembly.dll

with output like:

ProductVersion   FileVersion      FileName
--------------   -----------      --------
1.0.2907.18095   1.0.2907.18095   C:\Path\To\MyAssembly.dll

I've used it against an entire directory of assemblies with great success.

On express 3 you can use directly res.json({foo:bar})

res.json({ msgId: msg.fileName })

See the documentation

As i have implemented, and it is working fine. you just need to add column width using matColumnDef="description"

for example :

<mat-table #table [dataSource]="dataSource" matSortDisableClear>
    <ng-container matColumnDef="productId">
        <mat-header-cell *matHeaderCellDef>product ID</mat-header-cell>
        <mat-cell *matCellDef="let product">{{product.id}}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="productName">
        <mat-header-cell *matHeaderCellDef>Name</mat-header-cell>
        <mat-cell *matCellDef="let product">{{product.name}}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="actions">
        <mat-header-cell *matHeaderCellDef>Actions</mat-header-cell>
        <mat-cell *matCellDef="let product">
            <button (click)="view(product)">
                <mat-icon>visibility</mat-icon>
            </button>
        </mat-cell>
    </ng-container>
    <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
    <mat-row *matRowDef="let row; columns: displayedColumns"></mat-row>
</mat-table>

here matColumnDef is productId, productName and action

now we apply width by matColumnDef

styling

.mat-column-productId {
    flex: 0 0 10%;
}
.mat-column-productName {
    flex: 0 0 50%;
}

and remaining width is equally allocated to other columns

You want the gcc-specific noinline attribute.

This function attribute prevents a function from being considered for inlining. If the function does not have side-effects, there are optimizations other than inlining that causes function calls to be optimized away, although the function call is live. To keep such calls from being optimized away, put asm ("");

Use it like this:

void __attribute__ ((noinline)) foo() 
{
  ...
}

I got this error because in my code I misspelled a component definition with lowercase react.createClass instead of uppercase React.createClass.

You can also load the content with cURL, if file_get_contents insn't enabled on your server.

Example:

$ch = curl_init();  

curl_setopt($ch,CURLOPT_URL,"http://feeds.bbci.co.uk/sport/0/football/rss.xml?edition=int");
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

$output = curl_exec($ch);

curl_close($ch);

$items = simplexml_load_string($output);

This worked for me. I added alias and restarted my terminal:

alias python=/usr/local/bin/python3

You can convert ndarray to Series or DataFrame with pandas first, then you can use shift method as you want.

Example:

In [1]: from pandas import Series

In [2]: data = np.arange(10)

In [3]: data
Out[3]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

In [4]: data = Series(data)

In [5]: data
Out[5]: 
0    0
1    1
2    2
3    3
4    4
5    5
6    6
7    7
8    8
9    9
dtype: int64

In [6]: data = data.shift(3)

In [7]: data
Out[7]: 
0    NaN
1    NaN
2    NaN
3    0.0
4    1.0
5    2.0
6    3.0
7    4.0
8    5.0
9    6.0
dtype: float64

In [8]: data = data.values

In [9]: data
Out[9]: array([ nan,  nan,  nan,   0.,   1.,   2.,   3.,   4.,   5.,   6.])

This is where netstandard.dll exists: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.7.2\Facades\netstandard.dll Add ref to your Project through this.

This is the PHP ternary operator (also known as a conditional operator) - if first operand evaluates true, evaluate as second operand, else evaluate as third operand.

Think of it as an "if" statement you can use in expressions. Can be very useful in making concise assignments that depend on some condition, e.g.

$param = isset($_GET['param']) ? $_GET['param'] : 'default';

There's also a shorthand version of this (in PHP 5.3 onwards). You can leave out the middle operand. The operator will evaluate as the first operand if it true, and the third operand otherwise. For example:

$result = $x ?: 'default';

It is worth mentioning that the above code when using i.e. $_GET or $_POST variable will throw undefined index notice and to prevent that we need to use a longer version, with isset or a null coalescing operator which is introduced in PHP7:

$param = $_GET['param'] ?? 'default';

This is exactly what you want:

Once you read what What Every Computer Scientist Should Know About Floating-Point Arithmetic you could use the .toFixed() function:

var result = parseFloat('2.3') + parseFloat('2.4');
alert(result.toFixed(2));?

I use:

netstat –aon | find "<port number>"

here o represents process ID. now you can do whatever with the process ID. To terminate the process, for e.g., use:

taskkill /F /pid <process ID>

This is how you do it in your $(document).ready() function with FontAwesome Icons:

 $( ".owl-prev").html('<i class="fa fa-chevron-left"></i>');
 $( ".owl-next").html('<i class="fa fa-chevron-right"></i>');

In your .htaccess you can add:

PHP 5.x

<IfModule mod_php5.c>
    php_value memory_limit 64M
</IfModule>

PHP 7.x

<IfModule mod_php7.c>
    php_value memory_limit 64M
</IfModule>

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.

If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

A standard JavaScript solution:

var addition = [];
addition.push(2);
addition.push(3);

var total = 0;
for (var i = 0; i < addition.length; i++)
{
    total += addition[i];
}
alert(total);          // Just to output an example
/* console.log(total); // Just to output an example with Firebug */

This works for me (the result should be 5). I hope there is no hidden disadvantage in this kind of solution.

I suggest you take a look at tiny httpd. If you want to write it from scratch, then you'll want to thoroughly read RFC 2616. Use BSD sockets to access the network at a really low level.

Little correction at Line 3

HTMLParser.HTMLParser.__init__(self)

it should be

HTMLParser.__init__(self)

The following worked for me though

import urllib2 

from HTMLParser import HTMLParser  

class MyHTMLParser(HTMLParser):

  def __init__(self):
    HTMLParser.__init__(self)
    self.recording = 0 
    self.data = []
  def handle_starttag(self, tag, attrs):
    if tag == 'required_tag':
      for name, value in attrs:
        if name == 'somename' and value == 'somevale':
          print name, value
          print "Encountered the beginning of a %s tag" % tag 
          self.recording = 1 


  def handle_endtag(self, tag):
    if tag == 'required_tag':
      self.recording -=1 
      print "Encountered the end of a %s tag" % tag 

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

All modern browsers now support the unprefixed event:

element.addEventListener('transitionend', callback, false);

Works in the latest versions of Chrome, Firefox and Safari. Even IE10+.

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

ClickOnce apps are designed so that the end user downloads a "downloader" - the ClickOnce app, then when ya run it, it downloads and installs in %LocalAppData%\Apps\2.0..... and then it's random folder names for every OS install you do. Backing up is pointless and so is trying to move the program. The point of ClickOnce is 2-Fold: 1. AutoUpdating of the program 2. The end user has no installer and also can't move the app or it breaks

The %LocalAppData%\Apps\2.0..... folder is the program AND %LocalAppData%\GitHub is the settings folder.

I'm not going to cover how to circumvent this - only stating the above. :P

The best 'tip' I can say legitimately is: You 'can' in some cases move the final folder that all the files are in and use a symlink back, if you are low on space. But, not all apps will work and essentially will delete the symlink once you they run. Then they might reinstall or simply just remove the link. Keep in mind also, other apps may be using that same final folder as well, so move the folder will affect those too.

In each html template I just add the following meta tags at the top:

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

In my understanding each template is free standing therefore it does not inherit meta no caching rules setup in the index.html file.

I think this is the most reliable way to get the desktop path which isn't always the same as the username.

MsgBox CreateObject("WScript.Shell").specialfolders("Desktop")

If your proxy server or container adds the following header when serving the .js file, it will force some browsers such as Chrome to perform strict checking of MIME types:

X-Content-Type-Options: nosniff

Remove this header to prevent Chrome performing the MIME check.

Have you tried using JSONArray.getJSONObject(int), and JSONArray.length() to create your for-loop:

for (int i = 0; i < recs.length(); ++i) {
    JSONObject rec = recs.getJSONObject(i);
    int id = rec.getInt("id");
    String loc = rec.getString("loc");
    // ...
}

Through the UI in SQL Server 2005 manager, change the column remove the autonumber (identity) property of the column (select the table by right clicking on it and choose "Design").

Then run your query:

UPDATE table SET Id = Id + 1

Then go and add the autonumber property back to the column.

MySQL 5.7 supports computed columns. They call it "Generated Columns" and the syntax is a little weird, but it supports the same options I see in other databases.

https://dev.mysql.com/doc/refman/5.7/en/create-table.html#create-table-generated-columns

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

A very simple jquery function.

$(".datepicker").focus(function(event){
                var dim = $(this).offset();
                $("#ui-datepicker-div").offset({
                    top     :   dim.top - 180,
                    left    :   dim.left + 150
                });
            });

specify your marks:

List<Double> marks = new ArrayList<Double>();

This is called generics.

I am behind a corporate proxy, so I usually use an intermediate proxy to enable NTLM authentication.

I had hangs problem with npm install when using CNTLM proxy. With NTLM-APS (a similar proxy) the hangs were gone.

The best method I came up with was to just do a Registry query. Here is my example.

In my example I did an install using a Batch file that added new environment variables. I needed to do things with this as soon as the install was complete, but was unable to spawn a new process with those new variables. I tested spawning another explorer window and called back to cmd.exe and this worked but on Vista and Windows 7, Explorer only runs as a single instance and normally as the person logged in. This would fail with automation since I need my admin creds to do things regardless of running from local system or as an administrator on the box. The limitation to this is that it does not handle things like path, this only worked on simple enviroment variables. This allowed me to use a batch to get over to a directory (with spaces) and copy in files run .exes and etc. This was written today from may resources on stackoverflow.com

Orginal Batch calls to new Batch:

testenvget.cmd SDROOT (or whatever the variable)

@ECHO OFF
setlocal ENABLEEXTENSIONS
set keyname=HKLM\System\CurrentControlSet\Control\Session Manager\Environment
set value=%1
SET ERRKEY=0

REG QUERY "%KEYNAME%" /v "%VALUE%" 2>NUL| FIND /I "%VALUE%"
IF %ERRORLEVEL% EQU 0 (
ECHO The Registry Key Exists 
) ELSE (
SET ERRKEY=1
Echo The Registry Key Does not Exist
)

Echo %ERRKEY%
IF %ERRKEY% EQU 1 GOTO :ERROR

FOR /F "tokens=1-7" %%A IN ('REG QUERY "%KEYNAME%" /v "%VALUE%" 2^>NUL^| FIND /I "%VALUE%"') DO (
ECHO %%A
ECHO %%B
ECHO %%C
ECHO %%D
ECHO %%E
ECHO %%F
ECHO %%G
SET ValueName=%%A
SET ValueType=%%B
SET C1=%%C
SET C2=%%D
SET C3=%%E
SET C4=%%F
SET C5=%%G
)

SET VALUE1=%C1% %C2% %C3% %C4% %C5%
echo The Value of %VALUE% is %C1% %C2% %C3% %C4% %C5%
cd /d "%VALUE1%"
pause
REM **RUN Extra Commands here**
GOTO :EOF

:ERROR
Echo The the Enviroment Variable does not exist.
pause
GOTO :EOF

Also there is another method that I came up with from various different ideas. Please see below. This basically will get the newest path variable from the registry however, this will cause a number of issues beacuse the registry query is going to give variables in itself, that means everywhere there is a variable this will not work, so to combat this issue I basically double up the path. Very nasty. The more perfered method would be to do: Set Path=%Path%;C:\Program Files\Software....\

Regardless here is the new batch file, please use caution.

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS
set org=%PATH%
for /f "tokens=2*" %%A in ('REG QUERY "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v Path ^|FIND /I "Path"') DO (
SET path=%%B
)
SET PATH=%org%;%PATH%
set path

session_start();          //php part
$_SESSION['student']=array();
$student_name=$_POST['student_name']; //student_name form field name
$student_city=$_POST['city_id'];   //city_id form field name
array_push($_SESSION['student'],$student_name,$student_city);   
//print_r($_SESSION['student']);


<table class="table">     //html part
    <tr>
      <th>Name</th>
      <th>City</th>
    </tr>

    <tr>
     <?php for($i = 0 ; $i < count($_SESSION['student']) ; $i++) {
     echo '<td>'.$_SESSION['student'][$i].'</td>';
     }  ?>
    </tr>
</table>

As it was mentioned, there is no direct equivalent, but very close approximation could be created with Java bytecode modifications (for both async/await-like instructions and underlying continuations implementation).

I'm working right now on a project that implements async/await on top of JavaFlow continuation library, please check https://github.com/vsilaev/java-async-await

No Maven mojo is created yet, but you may run examples with supplied Java agent. Here is how async/await code looks like:

public class AsyncAwaitNioFileChannelDemo {

public static void main(final String[] argv) throws Exception {

    ...
    final AsyncAwaitNioFileChannelDemo demo = new AsyncAwaitNioFileChannelDemo();
    final CompletionStage<String> result = demo.processFile("./.project");
    System.out.println("Returned to caller " + LocalTime.now());
    ...
}


public @async CompletionStage<String> processFile(final String fileName) throws IOException {
    final Path path = Paths.get(new File(fileName).toURI());
    try (
            final AsyncFileChannel file = new AsyncFileChannel(
                path, Collections.singleton(StandardOpenOption.READ), null
            );              
            final FileLock lock = await(file.lockAll(true))
        ) {

        System.out.println("In process, shared lock: " + lock);
        final ByteBuffer buffer = ByteBuffer.allocateDirect((int)file.size());

        await( file.read(buffer, 0L) );
        System.out.println("In process, bytes read: " + buffer);
        buffer.rewind();

        final String result = processBytes(buffer);

        return asyncResult(result);

    } catch (final IOException ex) {
        ex.printStackTrace(System.out);
        throw ex;
    }
}

@async is the annotation that flags a method as asynchronously executable, await() is a function that waits on CompletableFuture using continuations and a call to "return asyncResult(someValue)" is what finalizes associated CompletableFuture/Continuation

As with C#, control flow is preserved and exception handling may be done in regular manner (try/catch like in sequentially executed code)

If you got here and you are using Debian/Ubuntu (or any other dpkg based distro), execute the following command:

sudo dpkg-reconfigure phpmyadmin

The phpmyadmin package contains the script to perform this operation for you, all it needs is a user with permissions. sudo is not required if you're logged in as root, of course.

EDIT: It might be worth trying to drop the current phpmyadmin user.

This will work if you wish to simply return an integer:

DECLARE @ResultForPos INT 
EXEC @ResultForPos = storedprocedureName 'InputParameter'
SELECT @ResultForPos

Installing psqlODBC on 64bit Windows

Though you can install 32 bit ODBC drivers on Win X64 as usual, you can't configure 32-bit DSNs via ordinary control panel or ODBC datasource administrator.

How to configure 32 bit ODBC drivers on Win x64

Configure ODBC DSN from %SystemRoot%\syswow64\odbcad32.exe

1. Start > Run
2. Enter: %SystemRoot%\syswow64\odbcad32.exe
3. Hit return.
4. Open up ODBC and select under the System DSN tab.
5. Select PostgreSQL Unicode

You may have to play with it and try different scenarios, think outside-the-box, remember this is open source.

I suggest you use curses.h or ncurses.h these implement keyboard management routines including getch(). You have several options to change the behavior of getch (i.e. wait for keypress or not).

You can use arguments with default values.

def someMethod(def mandatory,def optional=null){}

if argument "optional" not exist, it turns to "null".

There is a command-line utility xcodebuild and you can run shell command within xcode. So, if you don't mind using custom script, this script may help you.

#Configurations.
#This script designed for Mac OS X command-line, so does not use Xcode build variables.
#But you can use it freely if you want.

lipo -create -output "${RELEASE_UNIVERSAL_DIR}/${FILE_NAME}" "${RELEASE_DEVICE_DIR}/${FILE_NAME}" "${RELEASE_SIMULATOR_DIR}/${FILE_NAME}"

Maybe looks inefficient(I'm not good at shell script), but easy to understand. I configured a new target running only this script. The script is designed for command-line but not tested in :)

The core concept is xcodebuild and lipo.

I tried many configurations within Xcode UI, but nothing worked. Because this is a kind of batch processing, so command-line design is more suitable, so Apple removed batch build feature from Xcode gradually. So I don't expect they offer UI based batch build feature in future.

Valid hex colors can contain 0 to 9 and A to F so if we create a string with those characters and then shuffle it, we can grab the first 6 characters to create a random hex color code. An example is below!

code

echo '#' . substr(str_shuffle('ABCDEF0123456789'), 0, 6);

I tested this in a while loop and generated 10,000 unique colors.

code I used to generate 10,000 unique colors:

$colors = array();
while (true) {
   $color          = substr(str_shuffle('ABCDEF0123456789'), 0, 6);
   $colors[$color] = '#' . $color;
   if ( count($colors) == 10000 ) {
      echo implode(PHP_EOL, $colors);
      break;
   }
}

Which gave me these random colors as the result.

outis pointed out that my first example couldn't generate hexadecimals such as '4488CC' so I created a function which would be able to generate hexadecimals like that.

code

function randomHex() {
   $chars = 'ABCDEF0123456789';
   $color = '#';
   for ( $i = 0; $i < 6; $i++ ) {
      $color .= $chars[rand(0, strlen($chars) - 1)];
   }
   return $color;
}

echo randomHex();

The second example would be better to use because it can return a lot more different results than the first example, but if you aren't going to generate a lot of color codes then the first example would work just fine.

Suppose company C offers product P and P involves software in some way. Then C can offer a library/set of libraries to software developers that drive P's software systems.

That library/libraries are an SDK. It is part of the systems of P. It is a kit for software developers to use in order to modify, configure, fix, improve, etc the software piece of P.

If C wants to offer P's functionality to other companies/systems, it does so with an API.

This is an interface to P. A way for external systems to interact with P.

If you think in terms of implementation, they will seem quite similar. Especially now that the internet has become like one large distributed operating system.

In purpose, though, they are actually quite distinct.

You build something with an SDK and you use or consume something with an API.

I know this is an old post, but I found it and then found someone who suggested Total Mail Converter. I was able to convert my folder with 2k .msg files into .txt. It also allows you to convert into PDF and other popular formats.

It's a great tool that I am glad someone suggested as it will save me several days.

FYI - My project is combining the .msg files into one text file so that I can run a script to extract certain information from the files (ie: email and links). Instead of 2k files, I can work with one.

In case if you hate Inner classes, by taking the advantage of functional interface you can write less code in Java 8 with a lambda expression.

JsonDeserializer<Date> dateJsonDeserializer = 
     (json, typeOfT, context) -> json == null ? null : new Date(json.getAsLong());
Gson gson = new GsonBuilder().registerTypeAdapter(Date.class,dateJsonDeserializer).create();

Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.

Iterator<String> itr2 = keys.iterator();
    while(itr2.hasNext()){
        String v = itr2.next();
        System.out.println("Key: "+v+" ,value: "+m.get(v));
    }

private makes the class accessible only to the class in which it is declared. If we make entire class private no one from outside can access the class and makes it useless.

Inner class can be made private because the outer class can access inner class where as it is not the case with if you make outer class private.

I noticed that the first answer wasn't quite what I needed, so I made a couple of modifications and figured I'd post it back here.

Improved replaceTag(<tagName>)

replaceTag(<tagName>, [withDataAndEvents], [withDataAndEvents])

Arguments:

• tagName: String
  • The tag name e.g. "div", "span", etc.
• withDataAndEvents: Boolean
  • "A Boolean indicating whether event handlers should be copied along with the elements. As of jQuery 1.4, element data will be copied as well." info
• deepWithDataAndEvents: Boolean,
  • A Boolean indicating whether event handlers and data for all children of the cloned element should be copied. By default its value matches the first argument's value (which defaults to false)." info

Returns:

A newly created jQuery element

Okay, I know there are a few answers here now, but I took it upon myself to write this again.

Here we can replace the tag in the same way we use cloning. We are following the same syntax as .clone() with the withDataAndEvents and deepWithDataAndEvents which copy the child nodes' data and events if used.

Example:

$tableRow.find("td").each(function() {
  $(this).clone().replaceTag("li").appendTo("ul#table-row-as-list");
});

Source:

$.extend({
    replaceTag: function (element, tagName, withDataAndEvents, deepWithDataAndEvents) {
        var newTag = $("<" + tagName + ">")[0];
        // From [Stackoverflow: Copy all Attributes](http://stackoverflow.com/a/6753486/2096729)
        $.each(element.attributes, function() {
            newTag.setAttribute(this.name, this.value);
        });
        $(element).children().clone(withDataAndEvents, deepWithDataAndEvents).appendTo(newTag);
        return newTag;
    }
})
$.fn.extend({
    replaceTag: function (tagName, withDataAndEvents, deepWithDataAndEvents) {
        // Use map to reconstruct the selector with newly created elements
        return this.map(function() {
            return jQuery.replaceTag(this, tagName, withDataAndEvents, deepWithDataAndEvents);
        })
    }
})

Note that this does not replace the selected element, it returns the newly created one.

You can use curl or wget to retrieve the raw data, or you can use w3m -dump to have a nice text representation of a web page.

$ foo=$(w3m -dump http://www.example.com/); echo $foo
You have reached this web page by typing "example.com", "example.net","example.org" or "example.edu" into your web browser. These domain names are reserved for use in documentation and are not available for registration. See RFC 2606, Section 3.

This is as close as I can get to the natural feel of Python's "in" operator. You have to define your own type. Then you can extend the functionality of that type by adding a method like "has" which behaves like you'd hope.

package main

import "fmt"

type StrSlice []string

func (list StrSlice) Has(a string) bool {
    for _, b := range list {
        if b == a {
            return true
        }
    }
    return false
}

func main() {
    var testList = StrSlice{"The", "big", "dog", "has", "fleas"}

    if testList.Has("dog") {
        fmt.Println("Yay!")
    }
}

I have a utility library where I define a few common things like this for several types of slices, like those containing integers or my own other structs.

Yes, it runs in linear time, but that's not the point. The point is to ask and learn what common language constructs Go has and doesn't have. It's a good exercise. Whether this answer is silly or useful is up to the reader.

After a quality time I have found, theme option is the main problem in my code And following is the proper way to show the toolbar for me

In AndroidManifest file first you have to change your theme style

Theme.AppCompat.Light.DarkActionBar
to 
Theme.AppCompat.Light.NoActionBar

then at your activity xml you need to call your own Toolbar like

<androidx.appcompat.widget.Toolbar
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        android:id="@+id/toolbar"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:elevation="4dp"/>

And then this toolbar should be called in your Java file by

Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

And for toolbar showing U should check the null to avoid NullPointerException

if(getSupportActionBar() != null){
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

For Home activity back add this

@Override
public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId()==android.R.id.home) {
            finish();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

OR for your desired activity back

public boolean onOptionsItemSelected(MenuItem item){
    Intent myIntent = new Intent(getApplicationContext(), YourActivity.class);
    startActivityForResult(myIntent, 0);
    return true;
}

I am may be bit late for this, but I am able to resolve my issue of curl at cmd for windows 10.

I got help from below video tutorial https://www.youtube.com/watch?v=qlTVMuONazs

Here is some explanation

Step 1: go to https://curl.haxx.se/download.html

Step 2: Search "Win64 - Generic" and download "Win64 x86_64 7zip" by "Darren Owen"

Step 3: unzip the download file and install the certificate "ca-bundle.crt" do not touch curl.exe

Step 4: in windows go to "Control Panel" -> "System" -> "Advance system settings " Step 5: click on Envirnoment variables

Step 6: In System variable click on "Path" and paste the path of the file folder in my case it is "C:\curl\curl_7_53_1_openssl_nghttp2_x64"

And you are done.

Don't Forgot to restart you system for one time

A framework provides functionalities/solution to the particular problem area.
Definition from wiki:

A software framework, in computer programming, is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code providing specific functionality. Frameworks are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined Application programming interface (API), yet they contain some key distinguishing features that separate them from normal libraries.

This may be considered a hack but I've done this before using modelform_factory to turn a model instance into a form.

The Form class has a lot more information inside that's super easy to iterate over and it will serve the same purpose at the expense of slightly more overhead. If your set sizes are relatively small I think the performance impact would be negligible.

The one advantage besides convenience of course is that you can easily turn the table into an editable datagrid at a later date.

The following approach will sort the list in descending order and also handles the 'null' values, just in case if you have any null values then Collections.sort() will throw NullPointerException

      Collections.sort(list, new Comparator<Long>() {
          public int compare(Long o1, Long o2) {
                  return o1==null?Integer.MAX_VALUE:o2==null?Integer.MIN_VALUE:o2.compareTo(o1);

        }
    });

You just want to set the field separator as . using the -F option and print the first field:

$ echo aaa0.bbb.ccc | awk -F'.' '{print $1}'
aaa0

Same thing but using cut:

$ echo aaa0.bbb.ccc | cut -d'.' -f1
aaa0

Or with sed:

$ echo aaa0.bbb.ccc | sed 's/[.].*//'
aaa0

Even grep:

$ echo aaa0.bbb.ccc | grep -o '^[^.]*'
aaa0

Of C, A & P (Consistency, Availability & Partition tolerance) which 2 are more important to you? Quick reference, the Visual Guide To NoSQL Systems

• MongodB : Consistency and Partition Tolerance
• CouchDB : Availability and Partition Tolerance

A blog post, Cassandra vs MongoDB vs CouchDB vs Redis vs Riak vs HBase vs Membase vs Neo4j comparison has 'Best used' scenarios for each NoSQL database compared. Quoting the link,

• MongoDB: If you need dynamic queries. If you prefer to define indexes, not map/reduce functions. If you need good performance on a big DB. If you wanted CouchDB, but your data changes too much, filling up disks.
• CouchDB : For accumulating, occasionally changing data, on which pre-defined queries are to be run. Places where versioning is important.

A recent (Feb 2012) and more comprehensive comparison by Riyad Kalla,

• MongoDB : Master-Slave Replication ONLY
• CouchDB : Master-Master Replication

A blog post (Oct 2011) by someone who tried both, A MongoDB Guy Learns CouchDB commented on the CouchDB's paging being not as useful.

A dated (Jun 2009) benchmark by Kristina Chodorow (part of team behind MongoDB),

I'd go for MongoDB.

Hope it helps.

Your code is correct, except you are adding (concatenating) strings, not adding integers. Just change your code into:

function compute() {
    if ( $('input[name=type]:checked').val() != undefined ) {
        var a = parseInt($('input[name=service_price]').val());
        var b = parseInt($('input[name=modem_price]').val());
        var total = a+b;
        $('#total_price').val(a+b);
    }
}

and this should work.

Here is some working example that updates the sum when the value when checkbox is checked (and if this is checked, the value is also updated when one of the fields is changed): jsfiddle.

for example you can return list of all tables in database to the all views of Controller like this :

public function __construct()
{
    $tables = DB::select('SHOW TABLES'); // returns an array of stdObjects
    view()->share('tables', $tables);
}

I tried all suggested answers, but finally i made it work like this

if (false) //your condition
{
    $("a[data-toggle='tab'").prop('disabled', true);
    $("a[data-toggle='tab'").each(function () {
        $(this).prop('data-href', $(this).attr('href')); // hold you original href
        $(this).attr('href', '#'); // clear href
    });                
    $("a[data-toggle='tab'").addClass('disabled-link');
}
else
{
    $("a[data-toggle='tab'").prop('disabled', false);
    $("a[data-toggle='tab'").each(function () {
        $(this).attr('href', $(this).prop('data-href')); // restore original href
    });
    $("a[data-toggle='tab'").removeClass('disabled-link');
}
// if you want to show extra messages that the tab is disabled for a reason
$("a[data-toggle='tab'").click(function(){
   alert('Tab is disabled for a reason');
});

I found that

ALTER USER 'username'@'ip_address' IDENTIFIED WITH mysql_native_password BY 'password';

didn't work by itself. I also needed to set

[mysqld]
    default_authentication_plugin=mysql_native_password

in /etc/mysql/mysql.conf.d/mysqld.cnf on Ubuntu 18.04 running PHP 7.0

Now Android provides ViewModels for saving state, you should try to use that instead of saveInstanceState.

var $myForm = $('#myForm ');
if (!$myForm[0].checkValidity()) {
  $('<input type="submit">').hide().appendTo($myForm).click().remove();
}

If you want to format the JSON and also do some syntax highlighting, you can use the ng-prettyjson directive. See the npm package.

Here is how to use it: <pre pretty-json="jsonObject"></pre>

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

Neither of the suggested solutions worked for me. So I kept on searching for an alternative solution, which ended up being a mixture of the two before mentioned and a third step.

1. set the indent-number into the transformerfactory
2. enable the indent in the transformer
3. wrap the otuputstream with a writer (or bufferedwriter)

//(1)
TransformerFactory tf = TransformerFactory.newInstance();
tf.setAttribute("indent-number", new Integer(2));

//(2)
Transformer t = tf.newTransformer();
t.setOutputProperty(OutputKeys.INDENT, "yes");

//(3)
t.transform(new DOMSource(doc),
new StreamResult(new OutputStreamWriter(out, "utf-8"));

You must do (3) to workaround a "buggy" behavior of the xml handling code.

(If I have cited my source incorrectly please let me know)

string * and string& differ in a couple of ways. First of all, the pointer points to the address location of the data. The reference points to the data. If you had the following function:

int foo(string *param1);

You would have to check in the function declaration to make sure that param1 pointed to a valid location. Comparatively:

int foo(string &param1);

Here, it is the caller's responsibility to make sure the pointed to data is valid. You can't pass a "NULL" value, for example, int he second function above.

With regards to your second question, about the method return values being a reference, consider the following three functions:

string &foo();
string *foo();
string foo();

In the first case, you would be returning a reference to the data. If your function declaration looked like this:

string &foo()
{
    string localString = "Hello!";
    return localString;
}

You would probably get some compiler errors, since you are returning a reference to a string that was initialized in the stack for that function. On the function return, that data location is no longer valid. Typically, you would want to return a reference to a class member or something like that.

The second function above returns a pointer in actual memory, so it would stay the same. You would have to check for NULL-pointers, though.

Finally, in the third case, the data returned would be copied into the return value for the caller. So if your function was like this:

string foo()
{
    string localString = "Hello!";
    return localString;
}

You'd be okay, since the string "Hello" would be copied into the return value for that function, accessible in the caller's memory space.

Simple code that you can write in main(String[] args) function

    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//application will be closed when you close frame
    frame.setSize(800,600);
    frame.setLocation(200,200);

    JFileChooser fc = new JFileChooser();
    if(fc.showOpenDialog(frame) == JFileChooser.APPROVE_OPTION){
        BufferedImage img = ImageIO.read(fc.getSelectedFile());//it must be an image file, otherwise you'll get an exception
        JLabel label = new JLabel();
        label.setIcon(new ImageIcon(img));
        frame.getContentPane().add(label);
    }

    frame.setVisible(true);//showing up the frame

You need to add the command 'go' after you set the identity insert. Example:

SET IDENTITY_INSERT sometableWithIdentity ON
go

INSERT sometableWithIdentity (IdentityColumn, col2, col3, ...)
VALUES (AnIdentityValue, col2value, col3value, ...)

SET IDENTITY_INSERT sometableWithIdentity OFF
go

You should use NSIntegers if you need to compare them against constant values such as NSNotFound or NSIntegerMax, as these values will differ on 32-bit and 64-bit systems, so index values, counts and the like: use NSInteger or NSUInteger.

It doesn't hurt to use NSInteger in most circumstances, excepting that it takes up twice as much memory. The memory impact is very small, but if you have a huge amount of numbers floating around at any one time, it might make a difference to use ints.

If you DO use NSInteger or NSUInteger, you will want to cast them into long integers or unsigned long integers when using format strings, as new Xcode feature returns a warning if you try and log out an NSInteger as if it had a known length. You should similarly be careful when sending them to variables or arguments that are typed as ints, since you may lose some precision in the process.

On the whole, if you're not expecting to have hundreds of thousands of them in memory at once, it's easier to use NSInteger than constantly worry about the difference between the two.

If you are using a lot of memory and facing memory leaks, then you might want to check if you are using a large number of ArrayLists or HashMaps with many elements each.

An ArrayList is implemented as a dynamic array. The source code from Sun/Oracle shows that when a new element is inserted into a full ArrayList, a new array of 1.5 times the size of the original array is created, and the elements copied over. What this means is that you could be wasting up to 50% of the space in each ArrayList you use, unless you call its trimToSize method. Or better still, if you know the number of elements you are going to insert before hand, then call the constructor with the initial capacity as its argument.

I did not examine the source code for HashMap very carefully, but at a first glance it appears that the array length in each HashMap must be a power of two, making it another implementation of a dynamic array. Note that HashSet is essentially a wrapper around HashMap.

To Solve this Error in Webview Android, First Check the Permissions in Manifest.xml, if not define there,then define as like this. <uses-permission android:name="android.permission.INTERNET"/>

My solution requires the array be formatted differently than provided in the question:

<?
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );
?>

We define our function:

<?
    function outputCSV($data) {
        $outputBuffer = fopen("php://output", 'w');
        foreach($data as $val) {
            fputcsv($outputBuffer, $val);
        }
        fclose($outputBuffer);
    }
?>

Then we output our data as a CSV:

<?
    $filename = "example";

    header("Content-type: text/csv");
    header("Content-Disposition: attachment; filename={$filename}.csv");
    header("Pragma: no-cache");
    header("Expires: 0");

    outputCSV($data);
?>

I have used this with several projects, and it works well. I should note that the outputCSV code is more clever than I am, so I am sure I am not the original author. Unfortunately I have lost track of where I got it, so I can't give the credit to whom it is due.

The true way to send a broadcast from ADB command is :

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test from adb"

And, -a means ACTION, --es means to send a String extra.

PS. There are other data type you can send by specifying different params like:

[-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
[--esn <EXTRA_KEY> ...]
[--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
[--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
[--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...]
[--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE> ...]
[--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...]
[--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>]
[--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    (mutiple extras passed as Integer[])
[--eial <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    (mutiple extras passed as List<Integer>)
[--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    (mutiple extras passed as Long[])
[--elal <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    (mutiple extras passed as List<Long>)
[--efa <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]
    (mutiple extras passed as Float[])
[--efal <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]
    (mutiple extras passed as List<Float>)
[--esa <EXTRA_KEY> <EXTRA_STRING_VALUE>[,<EXTRA_STRING_VALUE...]]
    (mutiple extras passed as String[]; to embed a comma into a string,
     escape it using "\,")
[--esal <EXTRA_KEY> <EXTRA_STRING_VALUE>[,<EXTRA_STRING_VALUE...]]
    (mutiple extras passed as List<String>; to embed a comma into a string,
     escape it using "\,")
[-f <FLAG>]

For example, you can send an int value by:

--ei int_key 0

HTML doesn't have a built-in editable dropdown list or combobox, but I implemented a mostly-CSS solution in an article.

You can see a full demo here but in summary, write HTML like this:

<span class="combobox withtextlist">
  <input value="Fruit">
  <span tabindex="-1" class="downarrow"></span>
  <select size="10" class="sticky">
    <option>Apple</option>
    <option>Banana</option>
    <option>Cherry</option>
    <option>Dewberry</option>
  </select>
</span>

And use CSS like this to style it (this is designed for both comboboxes, which have a down-arrow ? button, and dropdown menus which open when clicked and may be styled differently):

/* ------------------------------------------ */
/* ----- combobox / dropdown list styling     */
/* ------------------------------------------ */
.combobox {
  /* Border slightly darker than Chrome's <select>, slightly lighter than FireFox's */
  border: 1px solid #999;
  padding-right: 1.25em; /* leave room for ? */
}
.dropdown, .combobox { 
  /* "relative" and "inline-block" (or just "block") are needed
     here so that "absolute" works correctly in children */
  position: relative;
  display: inline-block;
}
.combobox > .downarrow, .dropdown > .downarrow {
  /* ? Outside normal flow, relative to container */
  display: inline-block;
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  width: 1.25em;

  cursor: default;
  nav-index: -1; /* nonfunctional in most browsers */

  border-width: 0px;          /* disable by default */
  border-style: inherit; /* copy parent border */
  border-color: inherit; /* copy parent border */
}
/* Add a divider before the ? down arrow in non-dropdown comboboxes */
.combobox:not(.dropdown) > .downarrow {
  border-left-width: 1px;
}
/* Auto-down-arrow if one is not provided */
.downarrow:empty::before {
  content: '?';
}
.downarrow::before, .downarrow > *:only-child {
  text-align: center;

  /* vertical centering trick */
  position: relative;
  top: 50%;
  display: block; /* transform requires block/inline-block */
  transform: translateY(-50%);
}
.combobox > input {
  border: 0
}
.dropdown > *:last-child,
.combobox > *:last-child {
  /* Using `display:block` here has two desirable effects:
     (1) Accessibility: it lets input widgets in the dropdown to
         be selected with the tab key when the dropdown is closed. 
     (2) It lets the opacity transition work.
     But it also makes the contents visible, which is undesirable 
     before the list drops down. To compensate, use `opacity: 0`
     and disable mouse pointer events. Another side effect is that
     the user can select and copy the contents of the hidden list,
     but don't worry, the selected content is invisible. */
  display: block;
  opacity: 0;
  pointer-events: none;

  transition: 0.4s; /* fade out */

You also need some JavaScript to synchronize the list with the textbox:

function parentComboBox(el) {
    for (el = el.parentNode; el != null && Array.prototype.indexOf.call(el.classList, "combobox") <= -1;)
        el = el.parentNode;
    return el;
}
// Uses jQuery
$(".combobox.withtextlist > select").change(function() { 
  var textbox = parentComboBox(this).firstElementChild;
  textbox.value = this[this.selectedIndex].text;
});
$(".combobox.withtextlist > select").keypress(function(e) {
  if (e.keyCode == 13) // Enter pressed
    parentComboBox(this).firstElementChild.focus(); // Closes the popup
});

How about PlantUML? It's not for reverse engineering!!! It's for engineering before you code.

You should use the options 'year', 'month', and 'date' when initializing to specify the initial date value used by fullcalendar:

$('#calendar').fullCalendar({
 year: 2012,
 month: 4,
 date: 25
});  // This will initialize for May 25th, 2012.

See the function setYMD(date,y,m,d) in the fullcalendar.js file; note that the JavaScript setMonth, setDate, and setFullYear functions are used, so your month value needs to be 0-based (Jan is 0).

UPDATE: As others have noted in the comments, the correct way now (V3 as of writing this edit) is to initialize the defaultDate property to a value that is

anything the Moment constructor accepts, including an ISO8601 date string like "2014-02-01"

as it uses Moment.js. Documentation here.

Updated example:

$('#calendar').fullCalendar({
    defaultDate: "2012-05-25"
});  // This will initialize for May 25th, 2012.

In SQL Plus:

VAR rc REFCURSOR
EXEC gokul_proc(1,'GOKUL', :rc);
print rc

The Best form to hide and show a modal with bootstrap it's

// SHOW
$('#ModalForm').modal('show');
// HIDE
$('#ModalForm').modal('hide');

=VLOOKUP(LEFT(A4,LEN(A4)-9),$D:$F,3,0)

I use this if my Lookup_Value needs to be truncated because of the format the name is in the Table_Array. E.g. my Lookup_Value is "Eastbay District", but the Table_Array list I have only shows this as "Eastbay". "Eastbay District" minus 9 characters will result in "Eastbay".

I hope this helps!

CSS Keyframes support is pretty good these days:

.fade-in {_x000D_
 opacity: 1;_x000D_
 animation-name: fadeInOpacity;_x000D_

 animation-timing-function: ease-in;_x000D_
 animation-duration: 2s;_x000D_
}_x000D_
_x000D_
@keyframes fadeInOpacity {_x000D_
 0% {_x000D_
  opacity: 0;_x000D_
 }_x000D_
 100% {_x000D_
  opacity: 1;_x000D_
 }_x000D_
}

<h1 class="fade-in">Fade Me Down Scotty</h1>

document.getElementById('textbox-id').readOnly=true should work

Change column position:

ALTER TABLE Employees 
   CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;

If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:

ALTER TABLE UserOrder 
   CHANGE order_id order_id INT(11) NOT NULL FIRST;

Use update instead of stop

http://api.jqueryui.com/sortable/

update( event, ui )

Type: sortupdate

This event is triggered when the user stopped sorting and the DOM position has changed.

.

stop( event, ui )

Assuming your products LINQ class uses a similar yield for enumerating/iterating, the first version is more efficient because its only yielding one value each time its iterated over.

The second example is converting the enumerator/iterator to a list with the ToList() method. This means it manually iterates over all the items in the enumerator and then returns a flat list.

Technically speaking, the C standard only guarantees that sizeof(char) == 1, and the rest is up to the implementation. But on modern x86 architectures (e.g. Intel/AMD chips) it's fairly predictable.

You've probably heard processors described as being 16-bit, 32-bit, 64-bit, etc. This usually means that the processor uses N-bits for integers. Since pointers store memory addresses, and memory addresses are integers, this effectively tells you how many bits are going to be used for pointers. sizeof is usually measured in bytes, so code compiled for 32-bit processors will report the size of pointers to be 4 (32 bits / 8 bits per byte), and code for 64-bit processors will report the size of pointers to be 8 (64 bits / 8 bits per byte). This is where the limitation of 4GB of RAM for 32-bit processors comes from -- if each memory address corresponds to a byte, to address more memory you need integers larger than 32-bits.

In case of you decided the debug your apk which is already in market but not assigned to be debuggable and you do not want to publish it again. So follow the below steps;

1. Decompile the Apk with ApkTool(eg. apktool d <APK_PATH>)
2. Open the AndroidManifest.xml from decompiled files
3. Set android:debuggable="true" in application tag
4. Compile the modified source with ApkTool (eg. apktool b <MODIFIED_PATH>)
5. Debuggable apk ready(which unsigned means cannot publish store). You can debug as you wish.

Yes, the higher the z-index, the better. It will position your content element on top of every other element on the page. Say you have z-index to some elements on your page. Look for the highest and then give a higher z-index to your popup element. This way it will flow even over the other elements with z-index. If you don't have a z-index in any element on your page, you should give like z-index:2; or something higher.

I think you can do this which get your local file path

if not os.path.isdir(f_dir):
    os.mkdirs(f_dir)

try:
    approot = os.path.dirname(os.path.abspath(__file__))
except NameError:
    approot = os.path.dirname(os.path.abspath(sys.argv[1]))
    my_dir= os.path.join(approot, 'f_dir')

My understanding of the original question is two-fold. First, in terms of the simplest possible argparse example, I'm surprised that I haven't seen it here. Of course, to be dead-simple, it's also all overhead with little power, but it might get you started.

import argparse

parser = argparse.ArgumentParser()
parser.add_argument("a")
args = parser.parse_args()

if args.a == 'magic.name':
    print 'You nailed it!'

But this positional argument is now required. If you leave it out when invoking this program, you'll get an error about missing arguments. This leads me to the second part of the original question. Matt Wilkie seems to want a single optional argument without a named label (the --option labels). My suggestion would be to modify the code above as follows:

...
parser.add_argument("a", nargs='?', default="check_string_for_empty")
...
if args.a == 'check_string_for_empty':
    print 'I can tell that no argument was given and I can deal with that here.'
elif args.a == 'magic.name':
    print 'You nailed it!'
else:
    print args.a

There may well be a more elegant solution, but this works and is minimalist.

The following example the fastest (not parallelized) way list files and sub-folders in a directory tree handling exceptions. It would be faster to use Directory.EnumerateDirectories using SearchOption.AllDirectories to enumerate all directories, but this method will fail if hits a UnauthorizedAccessException or PathTooLongException.

Uses the generic Stack collection type, which is a last in first out (LIFO) stack and does not use recursion. From https://msdn.microsoft.com/en-us/library/bb513869.aspx, allows you to enumerate all sub-directories and files and deal effectively with those exceptions.

    public class StackBasedIteration
{
    static void Main(string[] args)
    {
        // Specify the starting folder on the command line, or in 
        // Visual Studio in the Project > Properties > Debug pane.
        TraverseTree(args[0]);

        Console.WriteLine("Press any key");
        Console.ReadKey();
    }

    public static void TraverseTree(string root)
    {
        // Data structure to hold names of subfolders to be
        // examined for files.
        Stack<string> dirs = new Stack<string>(20);

        if (!System.IO.Directory.Exists(root))
        {
            throw new ArgumentException();
        }
        dirs.Push(root);

        while (dirs.Count > 0)
        {
            string currentDir = dirs.Pop();
            string[] subDirs;
            try
            {
                subDirs = System.IO.Directory.EnumerateDirectories(currentDir); //TopDirectoryOnly
            }
            // An UnauthorizedAccessException exception will be thrown if we do not have
            // discovery permission on a folder or file. It may or may not be acceptable 
            // to ignore the exception and continue enumerating the remaining files and 
            // folders. It is also possible (but unlikely) that a DirectoryNotFound exception 
            // will be raised. This will happen if currentDir has been deleted by
            // another application or thread after our call to Directory.Exists. The 
            // choice of which exceptions to catch depends entirely on the specific task 
            // you are intending to perform and also on how much you know with certainty 
            // about the systems on which this code will run.
            catch (UnauthorizedAccessException e)
            {                    
                Console.WriteLine(e.Message);
                continue;

                continue;
            }

            string[] files = null;
            try
            {
                files = System.IO.Directory.EnumerateFiles(currentDir);
            }

            catch (UnauthorizedAccessException e)
            {

                Console.WriteLine(e.Message);
                continue;

            // Perform the required action on each file here.
            // Modify this block to perform your required task.
            foreach (string file in files)
            {
                try
                {
                    // Perform whatever action is required in your scenario.
                    System.IO.FileInfo fi = new System.IO.FileInfo(file);
                    Console.WriteLine("{0}: {1}, {2}", fi.Name, fi.Length, fi.CreationTime);
                }
                catch (System.IO.FileNotFoundException e)
                {
                    // If file was deleted by a separate application
                    //  or thread since the call to TraverseTree()
                    // then just continue.
                    Console.WriteLine(e.Message);
                    continue;

I had some problems with http.get; so I switched to the lib request:

var request = require('request');

var url = 'http://blog.mynotiz.de/';

var options = {
    url: url,
    method: 'HEAD'
};

request(options, function (error, response, body) {
        if (error) {
            return console.error('upload failed:', error);
        }

        if (response.headers['content-length']) {
            var file_size = response.headers['content-length'];
            console.log(file_size);
        }
    }
);

Easiest way, follow the steps :

step 1: After Archive project, right click on project and select show in finder

step 2: Right click on that project and select show as Show package contents, in that go to Products>Applications

step 3: Right click on projectname.app

step 4: Copy projectname.app into a empty folder and zip the folder(foldername.zip)

step 5: Change the zipfolder extension to .ipa(foldername.zip -> foldername.ipa)

step 6: Now you have the final .ipa file

The problem is that you are passing a nullable type to a non-nullable type.

You can do any of the following solution:

A. Declare your dt as nullable

DateTime? dt = dateTime;

B. Use Value property of the the DateTime? datetime

DateTime dt = datetime.Value;

C. Cast it

DateTime dt = (DateTime) datetime;

Also, the apt-show-versions package (installed separately) parses dpkg information about what is installed and tells you if packages are up to date.

Example..

$ sudo apt-show-versions --regex chrome
google-chrome-stable/stable upgradeable from 32.0.1700.102-1 to 35.0.1916.114-1
xserver-xorg-video-openchrome/quantal-security uptodate 1:0.3.1-0ubuntu1.12.10.1
$

Using float does not work.

DECLARE @t1 datetime, @t2 datetime
SELECT @t1 = '19000101 23:55:00', @t2 = '20001102 23:55:00'
SELECT CAST(@t1 as float) - floor(CAST(@t1 as float)), CAST(@t2 as float) - floor(CAST(@t2 as float))

You'll see that the values are not the same (SQL Server 2005). I wanted to use this method to check for times around midnight (the full method has more detail) in which I was comparing the current time for being between 23:55:00 and 00:05:00.

use FileInputStream's readLine() method to read and parse the returned String to int using Integer.parseInt() method.
