String money = output.replace(',', '.');

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

Here is the method I use:

double a=3.545555555; // just assigning your decimal to a variable
a=a*100;              // this sets a to 354.555555
a=Math.floor(a);      // this sets a to 354
a=a/100;              // this sets a to 3.54 and thus removing all your 5's

This can also be done:

a=Math.floor(a*100) / 100;

After reading all of the answers I ended up with this version with + a second function to use parameters as flags

function getURLParameter(name) {
    return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)','i').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null;
}

function isSetURLParameter(name) {
    return (new RegExp('[?|&]' + name + '(?:[=|&|#|;|]|$)','i').exec(location.search) !== null)
}

Your activity doesn't extend FragmentActivity from the support library, therefore the method is not present in the superclass

If you are targeting api 11 or above, you could use Activity.getFragmentManager instead.

In concurrency, the latest record may not be the record you just entered. It may better to get the latest record using the primary key.

If it is a auto increment field, use SELECT LAST_INSERT_ID(); to get the id you just created.

Assuming one has installed a JDK in /opt/java/jdk1.8.0_144 then:

1. Install the alternative for javac

   $ sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_144/bin/javac 1
   

2. Check / update the alternatives config:

   $ sudo update-alternatives --config javac
   

If there is only a single alternative for javac you will get a message saying so, otherwise select the option for the new JDK.

To check everything is setup correctly then:

$ which javac
/usr/bin/javac

$ ls -l /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep  4 17:10 /usr/bin/javac -> /etc/alternatives/javac

$ ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 32 Sep  4 17:10 /etc/alternatives/javac -> /opt/java/jdk1.8.0_144/bin/javac

And finally

$ javac -version
javac 1.8.0_144

Repeat for java, keytool, jar, etc as needed.

The easiest way:

add_compile_options(-std=c++11)

You should include <string.h> (or its C++ equivalent, <cstring>).

This fixed issues for me:

<style>
.super-centered {
    position:absolute; 
    width:100%;
    height:100%;
    text-align:center; 
    vertical-align:middle;
    z-index: 9999;
}
</style>

<table class="super-centered"><tr><td style="width:100%;height:100%;" align="center"     valign="middle" > 
<img alt="Loading ..." src="/ALHTheme/themes/html/ALHTheme/images/loading.gif">

For Linux to allow the edition of a log comment,

• locate the file pre-revprop-change.tmpl in the hooks directory of your repository
• copy the file to the same directory, renaming it to pre-revprop-change
• give execute permission to the file (for the server user, e.g. www-data)

Edited: (thanks to lindes)

• after that you might have to edit the script to return an exit value of 0 for the kind of edits, that you want to allow.

Getting height transitions to work can be a bit tricky mainly because you have to know the height to animate for. This is further complicated by padding in the element to be animated.

Here is what I came up with:

use a style like this:

    .slideup, .slidedown {
        max-height: 0;            
        overflow-y: hidden;
        -webkit-transition: max-height 0.8s ease-in-out;
        -moz-transition: max-height 0.8s ease-in-out;
        -o-transition: max-height 0.8s ease-in-out;
        transition: max-height 0.8s ease-in-out;
    }
    .slidedown {            
        max-height: 60px ;  // fixed width                  
    }

Wrap your content into another container so that the container you're sliding has no padding/margins/borders:

  <div id="Slider" class="slideup">
    <!-- content has to be wrapped so that the padding and
            margins don't effect the transition's height -->
    <div id="Actual">
            Hello World Text
        </div>
  </div>

Then use some script (or declarative markup in binding frameworks) to trigger the CSS classes.

  $("#Trigger").click(function () {
    $("#Slider").toggleClass("slidedown slideup");
  });

Example here: http://plnkr.co/edit/uhChl94nLhrWCYVhRBUF?p=preview

This works fine for fixed size content. For a more generic soltution you can use code to figure out the size of the element when the transition is activated. The following is a jQuery plug-in that does just that:

$.fn.slideUpTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.css("max-height", "0");
        $el.addClass("height-transition-hidden");
    });
};

$.fn.slideDownTransition = function() {
    return this.each(function() {
        var $el = $(this);
        $el.removeClass("height-transition-hidden");

        // temporarily make visible to get the size
        $el.css("max-height", "none");
        var height = $el.outerHeight();

        // reset to 0 then animate with small delay
        $el.css("max-height", "0");

        setTimeout(function() {
            $el.css({
                "max-height": height
            });
        }, 1);
    });
};

which can be triggered like this:

$("#Trigger").click(function () {

    if ($("#SlideWrapper").hasClass("height-transition-hidden"))
        $("#SlideWrapper").slideDownTransition();
    else
        $("#SlideWrapper").slideUpTransition();
});

against markup like this:

<style>
#Actual {
    background: silver;
    color: White;
    padding: 20px;
}

.height-transition {
    -webkit-transition: max-height 0.5s ease-in-out;
    -moz-transition: max-height 0.5s ease-in-out;
    -o-transition: max-height 0.5s ease-in-out;
    transition: max-height 0.5s ease-in-out;
    overflow-y: hidden;            
}
.height-transition-hidden {            
    max-height: 0;            
}
</style>
<div id="SlideWrapper" class="height-transition height-transition-hidden">
    <!-- content has to be wrapped so that the padding and
        margins don't effect the transition's height -->
    <div id="Actual">
     Your actual content to slide down goes here.
    </div>
</div>

This is similar to the scripts we generate on our team. Create the table first, then apply pk/fk and other constraints.

CREATE TABLE [dbo].[ImagenesUsuario] (
    [idImagen] [int] IDENTITY (1, 1) NOT NULL
)

ALTER TABLE [dbo].[ImagenesUsuario] ADD 
    CONSTRAINT [PK_ImagenesUsuario] PRIMARY KEY  CLUSTERED 
    (
        [idImagen]
    )  ON [PRIMARY] 

It must be at least 64 bits. Other than that it's implementation defined.

Strictly speaking, unsigned long long isn't standard in C++ until the C++0x standard. unsigned long long is a 'simple-type-specifier' for the type unsigned long long int (so they're synonyms).

The long long set of types is also in C99 and was a common extension to C++ compilers even before being standardized.

You'll probably want to try textContent instead of innerHTML.

Given innerHTML will return DOM content as a String and not exclusively the "text" in the div. It's fine if you know that your div contains only text but not suitable if every use case. For those cases, you'll probably have to use textContent instead of innerHTML

For example, considering the following markup:

<div id="test">
  Some <span class="foo">sample</span> text.
</div>

You'll get the following result:

var node = document.getElementById('test'),

htmlContent = node.innerHTML,
// htmlContent = "Some <span class="foo">sample</span> text."

textContent = node.textContent;
// textContent = "Some sample text."

See MDN for more details:

• textContent
• innerHTML

Send AJAX Http Requests to the server periodically (say once for every 60 seconds) through javascript to maintain session with the server until the file upload gets completed.

It's important to write full class path in the xml. I got 'Error inflating class' when only subclass's name was written in.

Avoid /etc/*release* files and run this command instead, it is far more reliable and gives more details:

rpm -qia '*release*'

There is no limit according to the HTTP protocol itself, but implementations will have a practical upper limit. I have sent data exceeding 4 GB using POST to Apache, but some servers did have a limit of 4 GB at the time.

DatePicker are not Select element. What your doing in your code is wrong.

Datepicker are in fact table with set of rows and columns.To select a date you just have to navigate to the cell where our desired date is present.

So your code should be like this:

WebElement dateWidget = driver.findElement(your locator);
List<WebElement> columns=dateWidget.findElements(By.tagName("td"));

for (WebElement cell: columns){
   //Select 13th Date 
   if (cell.getText().equals("13")){
      cell.findElement(By.linkText("13")).click();
      break;
 }

It sounds like some of your styles are being reset.

By default in most browsers, uls and ols have margin and padding added to them.

You can override this (and many do) by adding a line to your css like so

ul, ol {  //THERE MAY BE OTHER ELEMENTS IN THE LIST
    margin:0;
    padding:0;
}

In this case, you would remove the element from this list or add a margin/padding back, like so

ul{
    margin:1em;
}

The answer to your problem is easy: replace the current Fragment with the new Fragment and push transaction onto the backstack. This preserves back button behaviour...

Creating a new Activity really defeats the whole purpose to use fragments anyway...very counter productive.

@Override
public void onClick(View v) {
    // Create new fragment and transaction
    Fragment newFragment = new chartsFragment(); 
    // consider using Java coding conventions (upper first char class names!!!)
    FragmentTransaction transaction = getFragmentManager().beginTransaction();

    // Replace whatever is in the fragment_container view with this fragment,
    // and add the transaction to the back stack
    transaction.replace(R.id.fragment_container, newFragment);
    transaction.addToBackStack(null);

    // Commit the transaction
    transaction.commit(); 
}

On a higher level:

1) Async keyword enables the await and that's all it does. Async keyword does not run the method in a separate thread. The beginning f async method runs synchronously until it hits await on a time-consuming task.

2) You can await on a method that returns Task or Task of type T. You cannot await on async void method.

3) The moment main thread encounters await on time-consuming task or when the actual work is started, the main thread returns to the caller of the current method.

4) If the main thread sees await on a task that is still executing, it doesn't wait for it and returns to the caller of the current method. In this way, the application remains responsive.

5) Await on processing task, will now execute on a separate thread from the thread pool.

6) When this await task is completed, all the code below it will be executed by the separate thread

Below is the sample code. Execute it and check the thread id

using System;
using System.Threading;
using System.Threading.Tasks;

namespace AsyncAwaitDemo
{
    class Program
    {
        public static async void AsynchronousOperation()
        {
            Console.WriteLine("Inside AsynchronousOperation Before AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
            //Task<int> _task = AsyncMethod();
            int count = await AsyncMethod();

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod Before Await, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            //int count = await _task;

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod After Await Before DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            DependentMethod(count);

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod After Await After DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
        }

        public static async Task<int> AsyncMethod()
        {
            Console.WriteLine("Inside AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
            int count = 0;

            await Task.Run(() =>
            {
                Console.WriteLine("Executing a long running task which takes 10 seconds to complete, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
                Thread.Sleep(20000);
                count = 10;
            });

            Console.WriteLine("Completed AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            return count;
        }       

        public static void DependentMethod(int count)
        {
            Console.WriteLine("Inside DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId + ". Total count is " + count);
        }

        static void Main(string[] args)
        {
            Console.WriteLine("Started Main method, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            AsynchronousOperation();

            Console.WriteLine("Completed Main method, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            Console.ReadKey();
        }

    }
}

In case of not having the yaml file:

kubectl get pod PODNAME -n NAMESPACE -o yaml | kubectl replace --force -f -

You don't have to use Calendar. You can just play with timestamps :

Date d = initDate();//intialize your date to any date 
Date dateBefore = new Date(d.getTime() - n * 24 * 3600 * 1000 l ); //Subtract n days   

UPDATE DO NOT FORGET TO ADD "l" for long by the end of 1000.

Please consider the below WARNING:

Adding 1000*60*60*24 milliseconds to a java date will once in a great while add zero days or two days to the original date in the circumstances of leap seconds, daylight savings time and the like. If you need to be 100% certain only one day is added, this solution is not the one to use.

It might be late but may help someone, changing directory permissions worked for me.

Assuming that your Laravel project is in /var/www/html/ directory. Goto this directory.

cd /var/www/html/

Then change permissions of storage/ and bootstrap/cache/ directories.

sudo chmod -R 777 storage/
sudo chmod -R 777 bootstrap/cache/

This helped me to get remote branch before merging it into other:

git fetch repo xyz:xyz
git checkout xyz

        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {

According to current Backbone documentation....

view.remove()

Removes a view and its el from the DOM, and calls stopListening to remove any bound events that the view has listenTo'd.

Java 8 groupingBy Collector

Probably it's late but I like to share an improved idea to this problem. This is basically the same of @Vitalii Fedorenko's answer but more handly to play around.

You can just use the Collectors.groupingBy() by passing the grouping logic as function parameter and you will get the splitted list with the key parameter mapping. Note that using Optional is used to avoid the unwanted NPE when the provided list is null

public static <E, K> Map<K, List<E>> groupBy(List<E> list, Function<E, K> keyFunction) {
    return Optional.ofNullable(list)
            .orElseGet(ArrayList::new)
            .stream()
            .collect(Collectors.groupingBy(keyFunction));
}

Now you can groupBy anything with this. For the use case here in the question

Map<String, List<Student>> map = groupBy(studlist, Student::getLocation);

Maybe you would like to look into this also Guide to Java 8 groupingBy Collector

From http://spreadsheetpage.com/index.php/tip/making_an_exact_copy_of_a_range_of_formulas_take_2:

1. Put Excel in formula view mode. The easiest way to do this is to press Ctrl+` (that character is a "backwards apostrophe," and is usually on the same key that has the ~ (tilde).
2. Select the range to copy.
3. Press Ctrl+C
4. Start Windows Notepad
5. Press Ctrl+V to past the copied data into Notepad
6. In Notepad, press Ctrl+A followed by Ctrl+C to copy the text
7. Activate Excel and activate the upper left cell where you want to paste the formulas. And, make sure that the sheet you are copying to is in formula view mode.
8. Press Ctrl+V to paste.
9. Press Ctrl+` to toggle out of formula view mode.

Note: If the paste operation back to Excel doesn't work correctly, chances are that you've used Excel's Text-to-Columns feature recently, and Excel is trying to be helpful by remembering how you last parsed your data. You need to fire up the Convert Text to Columns Wizard. Choose the Delimited option and click Next. Clear all of the Delimiter option checkmarks except Tab.

In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<receiver 
    android:name=.NotificationCancelReceiver" >
    <intent-filter android:priority="999" >
         <action android:name="com.example.cancel" />
    </intent-filter>
</receiver>

In java File:

Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];

NotificationCancelReceiver

public class NotificationCancelReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Cancel your ongoing Notification
    };
}

Based on the clarifying comment by @user2989027, I think a good solution is the following:

definition = ['apple', 'ball']
data = {'orange':1, 'pear':2, 'apple':3, 'ball':4}
my_data = {}
for k in definition:
  try:
    my_data[k]=data[k]
  except KeyError:
    pass
print my_data

I tried not to do anything fancy here. I setup my data and an empty dictionary. I then loop through a list of strings that represent potential keys in my data dictionary. I copy each value from data to my_data, but consider the case where data may not have the key that I want.

setDatabasePath() method was deprecated in API level 19. I advise you to use storage locale like this:

    webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");

Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/

Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):

=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))

To translate your specific example, you would use:

=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))

html {
    overflow: scroll;

}

    width: 0px;  /* Remove scrollbar space */
    background: transparent;  /* Optional: just make scrollbar invisible */
}

In Python 3.x I do:

from pathlib import Path

path = Path(__file__).parent.absolute()

Explanation:

• Path(__file__) is the path to the current file.
• .parent gives you the directory the file is in.
• .absolute() gives you the full absolute path to it.

Using pathlib is the modern way to work with paths. If you need it as a string later for some reason, just do str(path).

If you want to cast it to specific type (e.g. within tests) you can use ReadAsAsync extension method:

object yourTypeInstance = await response.Content.ReadAsAsync(typeof(YourType));

or following for synchronous code:

object yourTypeInstance = response.Content.ReadAsAsync(typeof(YourType)).Result;

Update: there is also generic option of ReadAsAsync<> which returns specific type instance instead of object-declared one:

YourType yourTypeInstance = await response.Content.ReadAsAsync<YourType>();

Using the map() and reduce() built-in functions

def file_to_list(file):
     #stuff to parse file to a list
     return list

files = [...list of files...]

L = map(file_to_list, files)

flat_L = reduce(lambda x,y:x+y, L)

Minimal "for looping" and elegant coding pattern :)

I'm in Windows with WinSCP. It works great on both File Explorer and PuTTY SSH Shell to access my Amazon EC2-VPC Linux. There is nothing to do with chmod pem file as it uses myfile.ppk converted by PuTTYgen from the pem file.

This solution works if you are using asp.net validators:

<script language="javascript" type="text/javascript">
function disableButton(sender,group)
{
    Page_ClientValidate(group);
    if (Page_IsValid)
    {
        sender.disabled = "disabled";
        __doPostBack(sender.name, '');
    }
}</script>

and change the button:

<asp:Button runat="server" ID="btnSendMessage" Text="Send" OnClick="btnSendMessage_OnClick" OnClientClick="disableButton(this,'theValidationGroup')" CausesValidation="true" ValidationGroup="theValidationGroup" />

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

From MSDN:

Application.Exit

Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. This is the code to use if you are have called Application.Run (WinForms applications), this method stops all running message loops on all threads and closes all windows of the application.

Environment.Exit

Terminates this process and gives the underlying operating system the specified exit code. This is the code to call when you are using console application.

This article, Application.Exit vs. Environment.Exit, points towards a good tip:

You can determine if System.Windows.Forms.Application.Run has been called by checking the System.Windows.Forms.Application.MessageLoop property. If true, then Run has been called and you can assume that a WinForms application is executing as follows.

if (System.Windows.Forms.Application.MessageLoop) 
{
    // WinForms app
    System.Windows.Forms.Application.Exit();
}
else
{
    // Console app
    System.Environment.Exit(1);
}

Reference: Why would Application.Exit fail to work?

This is over simplifying it, but Express.js is to Node.js what Ruby on Rails or Sinatra is to Ruby.

Express 3.x is a light-weight web application framework to help organize your web application into an MVC architecture on the server side. You can use a variety of choices for your templating language (like EJS, Jade, and Dust.js).

You can then use a database like MongoDB with Mongoose (for modeling) to provide a backend for your Node.js application. Express.js basically helps you manage everything, from routes, to handling requests and views.

Redis is a key/value store -- commonly used for sessions and caching in Node.js applications. You can do a lot more with it, but that's what I'm using it for. I use MongoDB for more complex relationships, like line-item <-> order <-> user relationships. There are modules (most notably connect-redis) that will work with Express.js. You will need to install the Redis database on your server.

Here is a link to the Express 3.x guide: https://expressjs.com/en/3x/api.html

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:

• the field's tag is "-", or
• the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

Another solution:

z = 10
for x in range (z):
   y = z-x
   print y

Result:

10
9
8
7
6
5
4
3
2
1

Tip: If you are using this method to count back indices in a list, you will want to -1 from the 'y' value, as your list indices will begin at 0.

The isdigit method of the str type returns True iff the given string is nothing but one or more digits. If it's not, you know the string should be treated as just a string.

The accepted answer by @kevinsa5 is correct, but you might be thinking "I swear this code used to work and now it doesn't," and you would be right.

There was an API change in the MySQLdb library between 1.2.3 and 1.2.5. The 1.2.3 versions supported

cursor.execute("SELECT * FROM foo WHERE bar = %s", 'baz')

but the 1.2.5 versions require

cursor.execute("SELECT * FROM foo WHERE bar = %s", ['baz'])

as the other answers state. I can't find the change in the changelogs, and it's possible the earlier behavior was considered a bug.

The Ubuntu 14.04 repository has python-mysqldb 1.2.3, but Ubuntu 16.04 and later have python-mysqldb 1.3.7+.

If you're dealing with a legacy codebase that requires the old behavior but your platform is a newish Ubuntu, install MySQLdb from PyPI instead:

$ pip install MySQL-python==1.2.3

None of these answers really help if you are concerned with aligning the left border with other text fields on an input form.

I'd recommend positioning the dollar sign absolutely to the left about -10px or left 5px (depending whether you want it inside or outside the input box). The inside solution requires direction:rtl on the input css.

You could also add padding to the input to avoid the direction:rtl, but that will alter the width of the input container to not match the other containers of the same width.

<div style="display:inline-block">
 <div style="position:relative">
  <div style="position:absolute; left:-10px;">$</div>
 </div>
 <input type='text' />
</div>

or

<div style="display:inline-block">
 <div style="position:relative">
  <div style="position:absolute; left:5px;">$</div>
 </div>
 <input type='text' style='direction: rtl;' />
</div>

Iterating over strings is unfortunately rather slow in Python. Regular expressions are over an order of magnitude faster for this kind of thing. You just have to build the character class yourself. The unicodedata module is quite helpful for this, especially the unicodedata.category() function. See Unicode Character Database for descriptions of the categories.

import unicodedata, re, itertools, sys

all_chars = (chr(i) for i in range(sys.maxunicode))
categories = {'Cc'}
control_chars = ''.join(c for c in all_chars if unicodedata.category(c) in categories)
# or equivalently and much more efficiently
control_chars = ''.join(map(chr, itertools.chain(range(0x00,0x20), range(0x7f,0xa0))))

control_char_re = re.compile('[%s]' % re.escape(control_chars))

def remove_control_chars(s):
    return control_char_re.sub('', s)

For Python2

import unicodedata, re, sys

all_chars = (unichr(i) for i in xrange(sys.maxunicode))
categories = {'Cc'}
control_chars = ''.join(c for c in all_chars if unicodedata.category(c) in categories)
# or equivalently and much more efficiently
control_chars = ''.join(map(unichr, range(0x00,0x20) + range(0x7f,0xa0)))

control_char_re = re.compile('[%s]' % re.escape(control_chars))

def remove_control_chars(s):
    return control_char_re.sub('', s)

For some use-cases, additional categories (e.g. all from the control group might be preferable, although this might slow down the processing time and increase memory usage significantly. Number of characters per category:

• Cc (control): 65
• Cf (format): 161
• Cs (surrogate): 2048
• Co (private-use): 137468
• Cn (unassigned): 836601

Edit Adding suggestions from the comments.

Swift 5.1. Use with two extension, method return CALayer, so you would reuse it to update frames.

enum Border: Int {
    case top = 0
    case bottom
    case right
    case left
}

extension UIView {
    func addBorder(for side: Border, withColor color: UIColor, borderWidth: CGFloat) -> CALayer {
       let borderLayer = CALayer()
       borderLayer.backgroundColor = color.cgColor

       let xOrigin: CGFloat = (side == .right ? frame.width - borderWidth : 0)
       let yOrigin: CGFloat = (side == .bottom ? frame.height - borderWidth : 0)

       let width: CGFloat = (side == .right || side == .left) ? borderWidth : frame.width
       let height: CGFloat = (side == .top || side == .bottom) ? borderWidth : frame.height

       borderLayer.frame = CGRect(x: xOrigin, y: yOrigin, width: width, height: height)
       layer.addSublayer(borderLayer)
       return borderLayer
    }
}

extension CALayer {
    func updateBorderLayer(for side: Border, withViewFrame viewFrame: CGRect) {
        let xOrigin: CGFloat = (side == .right ? viewFrame.width - frame.width : 0)
        let yOrigin: CGFloat = (side == .bottom ? viewFrame.height - frame.height : 0)

        let width: CGFloat = (side == .right || side == .left) ? frame.width : viewFrame.width
        let height: CGFloat = (side == .top || side == .bottom) ? frame.height : viewFrame.height

        frame = CGRect(x: xOrigin, y: yOrigin, width: width, height: height)
    }
}

That's definitely the best way for any array whose length is a signed integral type. For arrays whose lengths are an unsigned integral type (e.g. an std::vector in C++), then you need to modify the end condition slightly:

for(size_t i = myArray.size() - 1; i != (size_t)-1; i--)
    // blah

If you just said i >= 0, this is always true for an unsigned integer, so the loop will be an infinite loop.

You can use a PowerShell script to look at registers and get the installed program details. The script bellow will generate a file with the complete list of installed programs. Save it with ".ps" extension and double click the file.

#
# Generates a full list of installed programs.
#

# Temporary auxiliar file.
$tmpFile = "tmp.txt"

# File that will hold the programs list.
$fileName = "programas-instalados.txt"

# Columns separator.
$separator = ","

# Delete previous files.
Remove-Item $tmpFile
Remove-Item $fileName

# Creates the temporary file.
Create-Item $tmpFile

# Searchs register for programs - part 1
$loc = Get-ChildItem HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall
$names = $loc |foreach-object {Get-ItemProperty $_.PsPath}
foreach ($name in $names)
{
    IF(-Not [string]::IsNullOrEmpty($name.DisplayName)) {      
        $line = $name.DisplayName+$separator+$name.DisplayVersion+$separator+$name.InstallDate
        Write-Host $line
        Add-Content $tmpFile "$line`n"        
    }
}

# Searchs register for programs - part 2
$loc = Get-ChildItem HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
$names = $loc |foreach-object {Get-ItemProperty $_.PsPath}
foreach ($name in $names)
{
    IF(-Not [string]::IsNullOrEmpty($name.DisplayName)) {      
        $line = $name.DisplayName+$separator+$name.DisplayVersion+$separator+$name.InstallDate
        Write-Host $line
        Add-Content $tmpFile "$line`n"
    }
}

# Sorts the result, removes duplicate lines and
# generates the final file.
gc $tmpFile | sort | get-unique > $filename

I created a little library functionality to solve these problems:

Instead of:

public T DifficultCalculation<T>(T a, T b)
{
    T result = a * b + a; // <== WILL NOT COMPILE!
    return result;
}
Console.WriteLine(DifficultCalculation(2, 3)); // Should result in 8.

You could write:

public T DifficultCalculation<T>(Number<T> a, Number<T> b)
{
    Number<T> result = a * b + a;
    return (T)result;
}
Console.WriteLine(DifficultCalculation(2, 3)); // Results in 8.

You can find the source code here: https://codereview.stackexchange.com/questions/26022/improvement-requested-for-generic-calculator-and-generic-number

Another alternative, not sure if this applies to your particular problem but to some it may be applicable is to use UnaryOperator in java.util.function library. where it returns same type you specify, so you put all your variables in one class and is it as a parameter:

public class FunctionsLibraryUse {

    public static void main(String[] args){
        UnaryOperator<People> personsBirthday = (p) ->{
            System.out.println("it's " + p.getName() + " birthday!");
            p.setAge(p.getAge() + 1);
            return p;
        };
        People mel = new People();
        mel.setName("mel");
        mel.setAge(27);
        mel = personsBirthday.apply(mel);
        System.out.println("he is now : " + mel.getAge());

    }
}
class People{
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

So the class you have, in this case Person, can have numerous instance variables and won't have to change the parameter of your lambda expression.

For those interested, I've written notes on how to use java.util.function library: http://sysdotoutdotprint.com/index.php/2017/04/28/java-util-function-library/

Just happened to us.

We were sure the cause is Apple's Christmas holoday (23-27 Dec 2016). But no - we've tried again 5 minutes later and the version passed.

However - the submission button is greyed out due to the holiday.

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

Functions like textcolor worked in old compilers like turbo C and Dev C. In today's compilers these functions would not work. I am going to give two function SetColor and ChangeConsoleToColors. You copy paste these functions code in your program and do the following steps.The code I am giving will not work in some compilers.

The code of SetColor is -

 void SetColor(int ForgC)
 {
     WORD wColor;

      HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
      CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
     if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
     {
                 //Mask out all but the background attribute, and add in the forgournd     color
          wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
          SetConsoleTextAttribute(hStdOut, wColor);
     }
     return;
 }

To use this function you need to call it from your program. For example I am taking your sample program -

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>

int main(void)
{
  SetColor(4);
  printf("\n \n \t This text is written in Red Color \n ");
  getch();
  return 0;
}

void SetColor(int ForgC)
 {
 WORD wColor;

  HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
  CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                 //Mask out all but the background attribute, and add in the forgournd color
      wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
      SetConsoleTextAttribute(hStdOut, wColor);
 }
 return;
}

When you run the program you will get the text color in RED. Now I am going to give you the code of each color -

Name         | Value
             |
Black        |   0
Blue         |   1
Green        |   2
Cyan         |   3
Red          |   4
Magenta      |   5
Brown        |   6
Light Gray   |   7
Dark Gray    |   8
Light Blue   |   9
Light Green  |   10
Light Cyan   |   11
Light Red    |   12
Light Magenta|   13
Yellow       |   14
White        |   15

Now I am going to give the code of ChangeConsoleToColors. The code is -

void ClearConsoleToColors(int ForgC, int BackC)
 {
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
  DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
}

In this function you pass two numbers. If you want normal colors just put the first number as zero and the second number as the color. My example is -

#include <windows.h>          //header file for windows
#include <stdio.h>

void ClearConsoleToColors(int ForgC, int BackC);

int main()
{
ClearConsoleToColors(0,15);
Sleep(1000);
return 0;
}
void ClearConsoleToColors(int ForgC, int BackC)
{
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
 DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
} 

In this case I have put the first number as zero and the second number as 15 so the console color will be white as the code for white is 15. This is working for me in code::blocks. Hope it works for you too.

To make more than one element fade in/out sequentially such as 5 elements fade each 4s,

1- make unique animation for each element with animation-duration equal to [ 4s (duration for each element) * 5 (number of elements) ] = 20s

animation-name: anim1 , anim2, anim3 ... 
animation-duration : 20s, 20s, 20s ... 

2- get animation keyframe for each element.

100% (keyframes percentage) / 5 (elements) = 20% (frame for each element)

3- define starting and ending point for each animation:

each animation has 20% frame length and @keyframes percentage always starts from 0%, so first animation will start from 0% and end in his frame(20%), and each next animation will starts from previous animation ending point and end when it reach his frame (+20% ),

@keyframes animation1 { 0% {}, 20% {}}
@keyframes animation2 { 20% {}, 40% {}}
@keyframes animation3 { 40% {}, 60% {}}
and so on

now we need to make each animation fade in from 0 to 1 opacity and fade out from 1 to 0,

so we will add another 2 points (steps) for each animation after starting and before ending point to handle the full opacity(1)

I tested each of the above methods for finding if any alphabets are contained in a given string and found out average processing time per string on a standard computer.

~250 ns for

import re

~3 µs for

re.search('[a-zA-Z]', string)

~6 µs for

any(c.isalpha() for c in string)

~850 ns for

string.upper().isupper()

Opposite to as alleged, importing re takes negligible time, and searching with re takes just about half time as compared to iterating isalpha() even for a relatively small string.
Hence for larger strings and greater counts, re would be significantly more efficient.

But converting string to a case and checking case (i.e. any of upper().isupper() or lower().islower() ) wins here. In every loop it is significantly faster than re.search() and it doesn't even require any additional imports.

You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:

body{
   min-width:1000px;        /* Suppose you want minimum width of 1000px */
   width: auto !important;  /* Firefox will set width as auto */
   width:1000px;            /* As IE6 ignores !important it will set width as 1000px; */
}

Or:

body{
   min-width:1000px; // Suppose you want minimum width of 1000px
   _width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}

You could also use lambda. Useful if you're using django.utils.timezone.now

date = models.DateField(_("Date"), default=lambda: now().date())

Yes, JavaScript variables will exist in the scope they are created.

var bannerID = 55;

<input id="EditBanner" type="button" 
  value="Edit Image" onclick="EditBanner(bannerID);"/>


function EditBanner(id) {
   //Do something with id
}

If you use event handlers and jQuery it is simple also

$("#EditBanner").click(function() {
   EditBanner(bannerID);
});

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

The html5 spec expressly rejects new lines in the place holder field. Versions of Webkit /will/ insert new lines when presented with line feeds in the placeholder, however this is incorrect behaviour and should not be relied upon.

I guess paragraphs aren't brief enough for w3 ;)

After looking at the previous responses, I hope this will help resolve any ambiguities. In case the similarities in the previous solutions and my solution are illusive, or this method of solving for roots is unclear, I've also made a graph which can be found here.

This is a working root function capable of solving for any nth-root

(default is square root for the sake of this question)

#include <cmath> 
// for "pow" function

double sqrt(double A, double root = 2) {
    const double e = 2.71828182846;
    return pow(e,(pow(10.0,9.0)/root)*(1.0-(pow(A,-pow(10.0,-9.0)))));
}

Explanation:

click here for graph

This works via Taylor series, logarithmic properties, and a bit of algebra.

Take, for example:

log A = N
   x

*Note: for square-root, N = 2; for any other root you only need to change the one variable, N.

1) Change the base, convert the base 'x' log function to natural log,

log A   =>   ln(A)/ln(x) = N
   x

2) Rearrange to isolate ln(x), and eventually just 'x',

ln(A)/N = ln(x)

3) Set both sides as exponents of 'e',

e^(ln(A)/N) = e^(ln(x))  >~{ e^ln(x) == x }~>  e^(ln(A)/N) = x

4) Taylor series represents "ln" as an infinite series,

ln(x) = (k=1)Sigma: (1/k)(-1^(k+1))(k-1)^n

           <~~~ expanded ~~~>

[(x-1)] - [(1/2)(x-1)^2] + [(1/3)(x-1)^3] - [(1/4)(x-1)^4] + . . .

*Note: Continue the series for increased accuracy. For brevity, 10^9 is used in my function which expresses the series convergence for the natural log with about 7 digits, or the 10-millionths place, for precision,

ln(x) = 10^9(1-x^(-10^(-9)))

5) Now, just plug in this equation for natural log into the simplified equation obtained in step 3.

e^[((10^9)/N)(1-A^(-10^-9)] = nth-root of (A)

6) This implementation might seem like overkill; however, its purpose is to demonstrate how you can solve for roots without having to guess and check. Also, it would enable you to replace the pow function from the cmath library with your own pow function:

double power(double base, double exponent) {
    if (exponent == 0) return 1;
    int wholeInt = (int)exponent;
    double decimal = exponent - (double)wholeInt;
    if (decimal) {
        int powerInv = 1/decimal;
        if (!wholeInt) return root(base,powerInv);
        else return power(root(base,powerInv),wholeInt,true);
    }
    return power(base, exponent, true);
}

double power(double base, int exponent, bool flag) {
    if (exponent < 0) return 1/power(base,-exponent,true);
    if (exponent > 0) return base * power(base,exponent-1,true);
    else return 1;
}

int root(int A, int root) {
    return power(E,(1000000000000/root)*(1-(power(A,-0.000000000001))));
}

You can simply set the window state

this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

Please try this.

 private boolean filemovetoanotherfolder(String sourcefolder, String destinationfolder, String filename) {
            boolean ismove = false;
            InputStream inStream = null;
            OutputStream outStream = null;

            try {

                File afile = new File(sourcefolder + filename);
                File bfile = new File(destinationfolder + filename);

                inStream = new FileInputStream(afile);
                outStream = new FileOutputStream(bfile);

                byte[] buffer = new byte[1024 * 4];

                int length;
                // copy the file content in bytes
                while ((length = inStream.read(buffer)) > 0) {

                outStream.write(buffer, 0, length);

                }


                // delete the original file
                afile.delete();
                ismove = true;
                System.out.println("File is copied successful!");

            } catch (IOException e) {
                e.printStackTrace();
            }finally{
               inStream.close();
               outStream.close();
            }
            return ismove;
            }

The other answers work for floating point numbers, but do not correctly compute the distance for integer dtypes which are subject to overflow and underflow. Note that even scipy.distance.euclidean has this issue:

>>> a1 = np.array([1], dtype='uint8')
>>> a2 = np.array([2], dtype='uint8')
>>> a1 - a2
array([255], dtype=uint8)
>>> np.linalg.norm(a1 - a2)
255.0
>>> from scipy.spatial import distance
>>> distance.euclidean(a1, a2)
255.0

This is common, since many image libraries represent an image as an ndarray with dtype="uint8". This means that if you have a greyscale image which consists of very dark grey pixels (say all the pixels have color #000001) and you're diffing it against black image (#000000), you can end up with x-y consisting of 255 in all cells, which registers as the two images being very far apart from each other. For unsigned integer types (e.g. uint8), you can safely compute the distance in numpy as:

np.linalg.norm(np.maximum(x, y) - np.minimum(x, y))

For signed integer types, you can cast to a float first:

np.linalg.norm(x.astype("float") - y.astype("float"))

For image data specifically, you can use opencv's norm method:

import cv2
cv2.norm(x, y, cv2.NORM_L2)

Why don't just use The Round-trip ("O", "o") Format Specifier?

The "O" or "o" standard format specifier represents a custom date and time format string using a pattern that preserves time zone information and emits a result string that complies with ISO 8601. For DateTime values, this format specifier is designed to preserve date and time values along with the DateTime.Kind property in text. The formatted string can be parsed back by using the DateTime.Parse(String, IFormatProvider, DateTimeStyles) or DateTime.ParseExact method if the styles parameter is set to DateTimeStyles.RoundtripKind.

The "O" or "o" standard format specifier corresponds to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string for DateTime values and to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" custom format string for DateTimeOffset values. In this string, the pairs of single quotation marks that delimit individual characters, such as the hyphens, the colons, and the letter "T", indicate that the individual character is a literal that cannot be changed. The apostrophes do not appear in the output string.

The O" or "o" standard format specifier (and the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string) takes advantage of the three ways that ISO 8601 represents time zone information to preserve the Kind property of DateTime values:

public class Example
{
   public static void Main()
   {
       DateTime dat = new DateTime(2009, 6, 15, 13, 45, 30, 
                                   DateTimeKind.Unspecified);
       Console.WriteLine("{0} ({1}) --> {0:O}", dat, dat.Kind); 

       DateTime uDat = new DateTime(2009, 6, 15, 13, 45, 30, 
                                    DateTimeKind.Utc);
       Console.WriteLine("{0} ({1}) --> {0:O}", uDat, uDat.Kind);

       DateTime lDat = new DateTime(2009, 6, 15, 13, 45, 30, 
                                    DateTimeKind.Local);
       Console.WriteLine("{0} ({1}) --> {0:O}\n", lDat, lDat.Kind);

       DateTimeOffset dto = new DateTimeOffset(lDat);
       Console.WriteLine("{0} --> {0:O}", dto);
   }
}
// The example displays the following output: 
//    6/15/2009 1:45:30 PM (Unspecified) --> 2009-06-15T13:45:30.0000000 
//    6/15/2009 1:45:30 PM (Utc) --> 2009-06-15T13:45:30.0000000Z 
//    6/15/2009 1:45:30 PM (Local) --> 2009-06-15T13:45:30.0000000-07:00 
//     
//    6/15/2009 1:45:30 PM -07:00 --> 2009-06-15T13:45:30.0000000-07:00

I don't see the benefit in aliasing out users tied to Schemas. Here is why....

Most people connect their user accounts to databases via roles initially, As soon as you assign a user to either the sysadmin, or the database role db_owner, in any form, that account is either aliased to the "dbo" user account, or has full permissions on a database. Once that occurs, no matter how you assign yourself to a scheme beyond your default schema (which has the same name as your user account), those dbo rights are assigned to those object you create under your user and schema. Its kinda pointless.....and just a namespace and confuses true ownership on those objects. Its poor design if you ask me....whomever designed it.

What they should have done is created "Groups", and thrown out schemas and role and just allow you to tier groups of groups in any combination you like, then at each tier tell the system if permissions are inherited, denied, or overwritten with custom ones. This would have been so much more intuitive and allowed DBA's to better control who the real owners are on those objects. Right now its implied in most cases the dbo default SQL Server user has those rights....not the user.

Each python object has a __dict__ atttribute which is a dictionary containing all other attributes. e.g. when you type self.attr python is actually doing self.__dict__['attr']. As you can imagine using a dictionary to store attribute takes some extra space & time for accessing it.

However, when you use __slots__, any object created for that class won't have a __dict__ attribute. Instead, all attribute access is done directly via pointers.

So if want a C style structure rather than a full fledged class you can use __slots__ for compacting size of the objects & reducing attribute access time. A good example is a Point class containing attributes x & y. If you are going to have a lot of points, you can try using __slots__ in order to conserve some memory.

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {res.EMAIL, res.USERNAME} );

OR you can use

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {email=res.EMAIL, username=res.USERNAME} );

Explanation :

1. Select employee from the db as res.

2. Filter the employee details as per the where condition.

3. Select required fields from the employee object by creating an Anonymous object using new { }

If I understand you correctly, you're talking about doing a

svn merge -rn:n-1

to back out of an earlier commit, in which case, you're probably looking for

git revert

This is official recommendation for upgrading Tensorflow.

To get TensorFlow 1.5, you can use the standard pip installation (or pip3 if you use python3)

$  pip install --ignore-installed --upgrade tensorflow

You can use --python option to npm like so:

npm install --python=python2.7

or set it to be used always:

npm config set python python2.7

Npm will in turn pass this option to node-gyp when needed.

(note: I'm the one who opened an issue on Github to have this included in the docs, as there were so many questions about it ;-) )

This should do the work:

    vertical-align: top;
}

There seems to be some confusion as to what type=bool and type='bool' might mean. Should one (or both) mean 'run the function bool(), or 'return a boolean'? As it stands type='bool' means nothing. add_argument gives a 'bool' is not callable error, same as if you used type='foobar', or type='int'.

But argparse does have registry that lets you define keywords like this. It is mostly used for action, e.g. `action='store_true'. You can see the registered keywords with:

parser._registries

which displays a dictionary

{'action': {None: argparse._StoreAction,
  'append': argparse._AppendAction,
  'append_const': argparse._AppendConstAction,
...
 'type': {None: <function argparse.identity>}}

There are lots of actions defined, but only one type, the default one, argparse.identity.

This code defines a 'bool' keyword:

def str2bool(v):
  #susendberg's function
  return v.lower() in ("yes", "true", "t", "1")
p = argparse.ArgumentParser()
p.register('type','bool',str2bool) # add type keyword to registries
p.add_argument('-b',type='bool')  # do not use 'type=bool'
# p.add_argument('-b',type=str2bool) # works just as well
p.parse_args('-b false'.split())
Namespace(b=False)

parser.register() is not documented, but also not hidden. For the most part the programmer does not need to know about it because type and action take function and class values. There are lots of stackoverflow examples of defining custom values for both.

In case it isn't obvious from the previous discussion, bool() does not mean 'parse a string'. From the Python documentation:

bool(x): Convert a value to a Boolean, using the standard truth testing procedure.

Contrast this with

int(x): Convert a number or string x to an integer.

Submit is null because it is not part of activity_main.xml

When you call findViewById inside an Activity, it is going to look for a View inside your Activity's layout.

try this instead :

Submit = (Button)loginDialog.findViewById(R.id.Submit);

Another thing : you use

android:layout_below="@+id/LoginTitle"

but what you want is probably

android:layout_below="@id/LoginTitle"

See this question about the difference between @id and @+id.

Since you need the tracks to close the streaming, and you need the stream boject to get to the tracks, the code I have used with the help of the Muaz Khan's answer above is as follows:

if (navigator.getUserMedia) {
    navigator.getUserMedia(constraints, function (stream) {
        videoEl.src = stream;
        videoEl.play();
        document.getElementById('close').addEventListener('click', function () {
            stopStream(stream);
        });
    }, errBack);

function stopStream(stream) {
console.log('stop called');
stream.getVideoTracks().forEach(function (track) {
    track.stop();
});

Of course this will close all the active video tracks. If you have multiple, you should select accordingly.

Not necessarily true. It will be encrypted on the wire however it still lands in the logs plain text

First of all, you should install SignalR.Host.Self on the server application and SignalR.Client on your client application by nuget :

PM> Install-Package SignalR.Hosting.Self -Version 0.5.2

PM> Install-Package Microsoft.AspNet.SignalR.Client

Then add the following code to your projects ;)

(run the projects as administrator)

Server console app:

using System;
using SignalR.Hubs;

namespace SignalR.Hosting.Self.Samples {
    class Program {
        static void Main(string[] args) {
            string url = "http://127.0.0.1:8088/";
            var server = new Server(url);

            // Map the default hub url (/signalr)
            server.MapHubs();

            // Start the server
            server.Start();

            Console.WriteLine("Server running on {0}", url);

            // Keep going until somebody hits 'x'
            while (true) {
                ConsoleKeyInfo ki = Console.ReadKey(true);
                if (ki.Key == ConsoleKey.X) {
                    break;
                }
            }
        }

        [HubName("CustomHub")]
        public class MyHub : Hub {
            public string Send(string message) {
                return message;
            }

            public void DoSomething(string param) {
                Clients.addMessage(param);
            }
        }
    }
}

Client console app:

using System;
using SignalR.Client.Hubs;

namespace SignalRConsoleApp {
    internal class Program {
        private static void Main(string[] args) {
            //Set connection
            var connection = new HubConnection("http://127.0.0.1:8088/");
            //Make proxy to hub based on hub name on server
            var myHub = connection.CreateHubProxy("CustomHub");
            //Start connection

            connection.Start().ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error opening the connection:{0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine("Connected");
                }

            }).Wait();

            myHub.Invoke<string>("Send", "HELLO World ").ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error calling send: {0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine(task.Result);
                }
            });

            myHub.On<string>("addMessage", param => {
                Console.WriteLine(param);
            });

            myHub.Invoke<string>("DoSomething", "I'm doing something!!!").Wait();


            Console.Read();
            connection.Stop();
        }
    }
}

One of the JPA ways for getting only particular columns is to ask for a Tuple object.

In your case you would need to write something like this:

CriteriaQuery<Tuple> cq = builder.createTupleQuery();
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<Tuple> tupleResult = em.createQuery(cq).getResultList();
for (Tuple t : tupleResult) {
    Long id = (Long) t.get(0);
    Long version = (Long) t.get(1);
}

Another approach is possible if you have a class representing the result, like T in your case. T doesn't need to be an Entity class. If T has a constructor like:

public T(Long id, Long version)

then you can use T directly in your CriteriaQuery constructor:

CriteriaQuery<T> cq = builder.createQuery(T.class);
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<T> result = em.createQuery(cq).getResultList();

See this link for further reference.

Stephen's answer is the one I'd use. For completeness, here's the DSU (decorate-sort-undecorate) pattern with list comprehensions:

decorated = [(tup[1], tup) for tup in data]
decorated.sort()
undecorated = [tup for second, tup in decorated]

Or, more tersely:

[b for a,b in sorted((tup[1], tup) for tup in data)]

As noted in the Python Sorting HowTo, this has been unnecessary since Python 2.4, when key functions became available.

I wrote and deployed a simple php-daemon, code is online here

https://github.com/jmullee/PhpUnixDaemon

Features: privilege dropping, signal handling, logging

I used it in a queue-handler (use case: trigger a lengthy operation from a web page, without making the page-generating php wait, i.e. launch an asynchronous operation) https://github.com/jmullee/PhpIPCMessageQueue

Again, after searching for the problem of converting nested lists with N levels into an N-dimensional array I found nothing, so here's my way around it:

import numpy as np

new_array=np.array([[[coord for coord in xk] for xk in xj] for xj in xi], ndmin=3) #this case for N=3

The problem with matplotlibs subplots_adjust is that the values you enter are relative to the x and y figsize of the figure. This example is for correct figuresizing for printing of a pdf:

For that, I recalculate the relative spacing to absolute values like this:

pyplot.subplots_adjust(left = (5/25.4)/figure.xsize, bottom = (4/25.4)/figure.ysize, right = 1 - (1/25.4)/figure.xsize, top = 1 - (3/25.4)/figure.ysize)

for a figure of 'figure.xsize' inches in x-dimension and 'figure.ysize' inches in y-dimension. So the whole figure has a left margin of 5 mm, bottom margin of 4 mm, right of 1 mm and top of 3 mm within the labels are placed. The conversion of (x/25.4) is done because I needed to convert mm to inches.

Note that the pure chart size of x will be "figure.xsize - left margin - right margin" and the pure chart size of y will be "figure.ysize - bottom margin - top margin" in inches

Other sniplets (not sure about these ones, I just wanted to provide the other parameters)

pyplot.figure(figsize = figureSize, dpi = None)

and

pyplot.savefig("outputname.eps", dpi = 100)

Well, this seemed to work on my Razor Page and never even did a round trip to the .cs file. This is old html way. It might be useful.

<input type="reset" value="Reset">

See the difference yourself:

DEMO

From Microsoft IE

The DOMContentLoaded event fires when parsing of the current page is complete; the load event fires when all files have finished loading from all resources, including ads and images. DOMContentLoaded is a great event to use to hookup UI functionality to complex web pages.

From Mozilla Developer Network

The DOMContentLoaded event is fired when the document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading (the load event can be used to detect a fully-loaded page).

BigDecimal value = new BigDecimal(10.0000);
value.setScale(4);

Yes you have to if you take the unique_ptr by value in the constructor. Explicity is a nice thing. Since unique_ptr is uncopyable (private copy ctor), what you wrote should give you a compiler error.

First set position of the parent DIV to relative (specifying the offset, i.e. left, top etc. is not necessary) and then apply position: absolute to the child DIV with the offset you want.
It's simple and should do the trick well.

I would recommend using the coding standards from IDesign or the ones listed on Brad Abram's website. Those are the best two that I have found.

Brad would say...

Classes member should be alphabetized, and grouped into sections (Fields, Constructors, Properties, Events, Methods, Private interface implementations, Nested types)

As commented by David Thomas, descendants of those child elements will (likely) inherit most of the styles assigned to those child elements.

You need to wrap your .myTestClass inside an element and apply the styles to descendants by adding .wrapper * descendant selector. Then, add .myTestClass > * child selector to apply the style to the elements children, not its grand children. For example like this:

JSFiddle - DEMO

.wrapper * {_x000D_
    color: blue;_x000D_
    margin: 0 100px; /* Only for demo */_x000D_
}_x000D_
.myTestClass > * {_x000D_
    color:red;_x000D_
    margin: 0 20px;_x000D_
}

<div class="wrapper">_x000D_
    <div class="myTestClass">Text 0_x000D_
        <div>Text 1</div>_x000D_
        <span>Text 1</span>_x000D_
        <div>Text 1_x000D_
            <p>Text 2</p>_x000D_
            <div>Text 2</div>_x000D_
        </div>_x000D_
        <p>Text 1</p>_x000D_
    </div>_x000D_
    <div>Text 0</div>_x000D_
</div>

The functions _compile_select() and _reset_select() are deprecated.
Instead use get_compiled_select():

#Create where clause
$this->db->select('id_cer');
$this->db->from('revokace');
$where_clause = $this->db->get_compiled_select();

#Create main query
$this->db->select('*');
$this->db->from('certs');
$this->db->where("`id` NOT IN ($where_clause)", NULL, FALSE);

        'password' => 'confirmed|min:6',
    ]);

Also ensure that "client tools" are selected in the install options. However if SQL Managment Studio 2008 exists then it is likely that you installed the express edition.

if (Data_Array["XML_File"] != "") String xmlfile = Data_Array["XML_File"];

The easiest way to achieve this is to create only 1 table with both Table A and B fields NOT NULL. This way it is impossible to have one without the other.

You can just check if the variable has a value or not. Meaning,

if( myVariable ) {
//mayVariable is not :
//null
//undefined
//NaN
//empty string ("")
//0
//false

}

If you do not know whether a variable exists (that means, if it was declared) you should check with the typeof operator. e.g.

if( typeof myVariable !== 'undefined' ) {
    // myVariable will get resolved and it is defined
}

If you only want to get one day it would be easier this way:

Comment.all(:conditions => ["date(created_at) = ?", some_date])

do it this way

         create table person(
         personid int identity(1,1) primary key,
         firstname varchar(20),
         lastname varchar(20),
         addressindex int,
         sound varchar(10)
         )

and later on create a trigger

         create trigger trigoninsert for dbo.person
         on insert 
         as
         declare @personid int;
         select @personid=personid from inserted;
         update person
         set sound=soundex(firstname) where personid=@personid;

now what i can do is i can create a procedure which looks something like this

         create procedure getfuzzi(@personid int)
          as
         declare @sound varchar(10);
         set @sound=(select sound from person where personid=@personid;
         select personid,firstname,lastname,addressindex from person
         where sound=@sound

this will return you all the names that are nearly in match with the names provided by for a particular personid

I found a reference to this in condas issues. The following should now work.

To add my two cents to the conversation a process can have simultaneously open a number of sockets connected equal to this number (in Linux type sytems) /proc/sys/net/core/somaxconn

cat /proc/sys/net/core/somaxconn

This number can be modified on the fly (only by root user of course)

echo 1024 > /proc/sys/net/core/somaxconn

But entirely depends on the server process, the hardware of the machine and the network, the real number of sockets that can be connected before crashing the system

According to this issue, it was a design decision to not allow users to modify the Webpack configuration to reduce the learning curve.

Considering the number of useful configuration on Webpack, this is a great drawback.

I would not recommend using angular-cli for production applications, as it is highly opinionated.

• install stylebot extension from webstore https://chrome.google.com/webstore/detail/stylebot/oiaejidbmkiecgbjeifoejpgmdaleoha
• go to G-document, set appropriate minimal view mode
• click stylebot icon (css) in toolbar of Chrome
• click "Open Stylebot"
• on very first line of new window, which is reading "select an element", insert text .kix-page-compact::before
• set border-style to none

Other than that open the "View" menu at the top of the screen and un-check "Print Layout." Page breaks will now only be shown as a dashed line.

As @Amir posted above, the best way nowadays – cross-browser and leaving behind IE6 – is to use

[type=text] {}

Nobody mentioned lower CSS specificity (why is that important?) so far, [type=text] features 0,0,1,0 instead of 0,0,1,1 with input[type=text].

Performance-wise there's no negative impact at all any more.

normalize v4.0.0 just released with lowered selector specificity.

If you want to use SQL Server Management Studio, you want to install the full Oracle client, not the Instant Client. The full Oracle client is on the same download page as the Oracle database. Assuming that you are installing on a 64-bit version of Windows, I expect you want the "Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64)" download. This is several hundred MB rather than a couple of MB for the Instant Client.

a more modern approach would be to use css flex-box.

div {_x000D_
  height: 50px;_x000D_
  background: grey;_x000D_
  display: flex;_x000D_
  align-items: center_x000D_
}

<div>_x000D_
  <label for='name'>Name:</label>_x000D_
  <input type='text' id='name' />_x000D_
</div>

a more complex example... if you have multible elements in the flex flow, you can use align-self to align single elements differently to the specified align...

div {_x000D_
  display: flex;_x000D_
  align-items: center_x000D_
}_x000D_
_x000D_
* {_x000D_
  margin: 10px_x000D_
}_x000D_
_x000D_
label {_x000D_
  align-self: flex-start_x000D_
}

<div>_x000D_
  <img src="https://de.gravatar.com/userimage/95932142/195b7f5651ad2d4662c3c0e0dccd003b.png?size=50" />_x000D_
  <label>Text</label>_x000D_
  <input placeholder="Text" type="text" />_x000D_
</div>

its also super easy to center horizontally and vertically:

div {_x000D_
  position:absolute;_x000D_
  top:0;left:0;right:0;bottom:0;_x000D_
  background: grey;_x000D_
  display: flex;_x000D_
  align-items: center;_x000D_
  justify-content:center_x000D_
}

<div>_x000D_
  <label for='name'>Name:</label>_x000D_
  <input type='text' id='name' />_x000D_
</div>

Here's another take on the data.table answers, using @Carson's data, that's a bit more readable (and also a little faster, because of using lapply instead of sapply):

library(data.table)
set.seed(1)
dt = data.table(ID=c(1:3), Obs_1=rnorm(9), Obs_2=rnorm(9), Obs_3=rnorm(9))

dt[, c(mean = lapply(.SD, mean), sd = lapply(.SD, sd)), by = ID]
#   ID mean.Obs_1 mean.Obs_2 mean.Obs_3  sd.Obs_1  sd.Obs_2  sd.Obs_3
#1:  1  0.4854187 -0.3238542  0.7410611 1.1108687 0.2885969 0.1067961
#2:  2  0.4171586 -0.2397030  0.2041125 0.2875411 1.8732682 0.3438338
#3:  3 -0.3601052  0.8195368 -0.4087233 0.8105370 0.3829833 1.4705692

It's running every minute of the hour 22 I guess. Try the following to run it every first minute of the hour 22:

0 22 * * * ....

It is better to use .hasClass() when you want to check if an element has a particular class. This is because when an element has multiple class it is not trivial to check.

Example:

<div id='test' class='main divhover'></div>

Where:

$('#test').attr('class');        // returns `main divhover`.

With .hasClass() we can test if the div has the class divhover.

$('#test').hasClass('divhover'); // returns true
$('#test').hasClass('main');     // returns true

SELECT * FROM mysql.user;

It's a big table so you might want to be more selective on what fields you choose.

You can use this code snippet for creating a two buttoned Alert box,

import 'package:flutter/material.dart';

class BaseAlertDialog extends StatelessWidget {

  //When creating please recheck 'context' if there is an error!

  Color _color = Color.fromARGB(220, 117, 218 ,255);

  String _title;
  String _content;
  String _yes;
  String _no;
  Function _yesOnPressed;
  Function _noOnPressed;

  BaseAlertDialog({String title, String content, Function yesOnPressed, Function noOnPressed, String yes = "Yes", String no = "No"}){
    this._title = title;
    this._content = content;
    this._yesOnPressed = yesOnPressed;
    this._noOnPressed = noOnPressed;
    this._yes = yes;
    this._no = no;
  }

  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: new Text(this._title),
      content: new Text(this._content),
      backgroundColor: this._color,
      shape:
          RoundedRectangleBorder(borderRadius: new BorderRadius.circular(15)),
      actions: <Widget>[
        new FlatButton(
          child: new Text(this._yes),
          textColor: Colors.greenAccent,
          onPressed: () {
            this._yesOnPressed();
          },
        ),
        new FlatButton(
          child: Text(this._no),
          textColor: Colors.redAccent,
          onPressed: () {
            this._noOnPressed();
          },
        ),
      ],
    );
  }
}

To show the dialog you can have a method that calls it NB after importing BaseAlertDialog class

_confirmRegister() {
var baseDialog = BaseAlertDialog(
    title: "Confirm Registration",
    content: "I Agree that the information provided is correct",
    yesOnPressed: () {},
    noOnPressed: () {},
    yes: "Agree",
    no: "Cancel");
showDialog(context: context, builder: (BuildContext context) => baseDialog);
}

OUTPUT WILL BE LIKE THIS

The area of abcd`s PDF is not one, which is impossible like pointed out in many comments. Assumptions done in many answers here

1. Assume constant distance between consecutive edges.
2. Probability under pdf should be 1. The normalization should be done as Normalization with probability, not as Normalization with pdf, in histogram() and hist().

Fig. 1 Output of hist() approach, Fig. 2 Output of histogram() approach

The max amplitude differs between two approaches which proposes that there are some mistake in hist()'s approach because histogram()'s approach uses the standard normalization. I assume the mistake with hist()'s approach here is about the normalization as partially pdf, not completely as probability.

Code with hist() [deprecated]

Some remarks

1. First check: sum(f)/N gives 1 if Nbins manually set.
2. pdf requires the width of the bin (dx) in the graph g

Code

%http://stackoverflow.com/a/5321546/54964
N=10000;
Nbins=50;
[f,x]=hist(randn(N,1),Nbins); % create histogram from ND

%METHOD 4: Count Densities, not Sums!
figure(3)
dx=diff(x(1:2)); % width of bin
g=1/sqrt(2*pi)*exp(-0.5*x.^2) .* dx; % pdf of ND with dx
% 1.0000
bar(x, f/sum(f));hold on
plot(x,g,'r');hold off

Output is in Fig. 1.

Code with histogram()

Some remarks

1. First check: a) sum(f) is 1 if Nbins adjusted with histogram()'s Normalization as probability, b) sum(f)/N is 1 if Nbins is manually set without normalization.
2. pdf requires the width of the bin (dx) in the graph g

Code

    midPointShift=abs(edges(counter)-edges(counter+1))/2; % same constant for all
    x(counter)=edges(counter)+midPointShift;

You don't need jQuery, just use javascript's Math.random function.

edit: If you want to have a number from 1 to 6 show randomly every second, you can do something like this:

<span id="number"></span>

<script language="javascript">
  function generate() {
    $('#number').text(Math.floor(Math.random() * 6) + 1);
  }
  setInterval(generate, 1000);
</script>

1. You can use an enum type in Java 5 and onwards for the purpose you have described. It is type safe.
2. A is an instance variable. (If it has the static modifier, then it becomes a static variable.) Constants just means the value doesn't change.
3. Instance variables are data members belonging to the object and not the class. Instance variable = Instance field.

If you are talking about the difference between instance variable and class variable, instance variable exist per object created. While class variable has only one copy per class loader regardless of the number of objects created.

Java 5 and up enum type

public enum Color{
 RED("Red"), GREEN("Green");

 private Color(String color){
    this.color = color;
  }

  private String color;

  public String getColor(){
    return this.color;
  }

  public String toString(){
    return this.color;
  }
}

If you wish to change the value of the enum you have created, provide a mutator method.

public enum Color{
 RED("Red"), GREEN("Green");

 private Color(String color){
    this.color = color;
  }

  private String color;

  public String getColor(){
    return this.color;
  }

  public void setColor(String color){
    this.color = color;
  }

  public String toString(){
    return this.color;
  }
}

Example of accessing:

public static void main(String args[]){
  System.out.println(Color.RED.getColor());

  // or

  System.out.println(Color.GREEN);
}

In my case I needed to control what was the previous element. I then created a stateful Predicate where I controled if the previous element was different from the current element, in that case I kept it.

public List<Log> fetchLogById(Long id) {
    return this.findLogById(id).stream()
        .filter(new LogPredicate())
        .collect(Collectors.toList());
}

public class LogPredicate implements Predicate<Log> {

    private Log previous;

    public boolean test(Log atual) {
        boolean isDifferent = previouws == null || verifyIfDifferentLog(current, previous);

        if (isDifferent) {
            previous = current;
        }
        return isDifferent;
    }

    private boolean verifyIfDifferentLog(Log current, Log previous) {
        return !current.getId().equals(previous.getId());
    }

}

It’s a chicken-and-egg problem. You won’t be able to do it because you need to load the assets to display the progress bar widget, by which time your page will be either fully or partially downloaded. Also, you need to know the total size of the page prior to the user requesting in order to calculate a percentage.

It’s more hassle than it’s worth.

sudo apt-get update   
sudo apt purge python2.7-minimal

From my understanding, fixed-point arithmetic is done using integers. where the decimal part is stored in a fixed amount of bits, or the number is multiplied by how many digits of decimal precision is needed.

For example, If the number 12.34 needs to be stored and we only need two digits of precision after the decimal point, the number is multiplied by 100 to get 1234. When performing math on this number, we'd use this rule set. Adding 5620 or 56.20 to this number would yield 6854 in data or 68.54.

If we want to calculate the decimal part of a fixed-point number, we use the modulo (%) operand.

12.34 (pseudocode):

v1 = 1234 / 100 // get the whole number
v2 = 1234 % 100 // get the decimal number (100ths of a whole).
print v1 + "." + v2 // "12.34"

Floating point numbers are a completely different story in programming. The current standard for floating point numbers use something like 23 bits for the data of the number, 8 bits for the exponent, and 1 but for sign. See this Wikipedia link for more information on this.

GitHub Gists

To gist or not to gist. That is the $64 question ...

GitHub Gists are Single ( or, multiple ) Simple Markdown Files with repo-like qualities that can be forked or cloned ( if public ).

Otherwise, not if private.

Kinda like a fancy scratch pad that can be shared.

Similar to this comment scratch pad that I am typing on now, but a bit more elaborate.

Whereas, an official, full GitHub repo is a full blown repository of source code src, supporting documents ( markdown or html, or both ) docs or root, images png, ico, svg, and a config.sys file for running Yaml variables hosted on a Jekyll server.

Does a simple Gist file support Yaml front matter?

Me thinks not.

From the official GitHub Gist documentation ...

The gist editor is powered by CodeMirror.

However, you can copy a public Gist ( or, a private Gist if the owner has granted you access via a link to the private Gist ) ...

And, you can then embed that public Gist into an "official" repo page.md using Visual Studio Code, as follows:

"You can embed a gist in any text field that supports Javascript, such as a blog post."

"To get the embed code, click the clipboard icon next to the Embed URL button of a gist."

Now, that's a cool feature.

Makes me want to search ( discover ) other peoples' gists, or OPG and incorporate their "public" work into my full-blown working repos.

"You can discover the PUBLIC gists others have created by going to the gist home page and clicking on the link ...

All Gists{:title='Click to Review the Discover Feature at GitHub Gists'}{:target='_blank'}."

Caveat. No support for Liquid tags at GitHub Gist.

I suppose if I do find something beneficial, I can always ping-back, or cite that source if I do use the work in my full-blown working repos.

Where is the implicit license posted for all gists made public by their authors?

P.S. This is a good comment. I think I will turn this into a gist and make it publically searchable over at GitHub Gists.

Note. When embedding the <script></script> html tag within the body of a Markdown (.md) file, you may get a warning "MD033" from your linter.

This should not, however, affect the rendering of the data ( src ) called from within the script tag.

To change the default warning flag to accommodate the called contents of a script tag from within Visual Studio Code, add an entry to the Markdownlint Configuration Object within the User Settings Json file, as follows:

// Begin Markdownlint Configuration Object
"markdownlint.config": {
  "MD013": false,
  "MD033": {"allowed_elements": ["script"]}
}// End Markdownlint Configuration Object

For python 3.6

class SomeClass:

    def attr_list(self, should_print=False):

        items = self.__dict__.items()
        if should_print:
            [print(f"attribute: {k}    value: {v}") for k, v in items]

        return items

If you don't mind using jQuery, then you can use offset() function. Refer to documentation if you want to read up more about this function.

First, to describe dynamic cast in C terms, we have to represent classes in C. Classes with virtual functions use a "VTABLE" of pointers to the virtual functions. Comments are C++. Feel free to reformat and fix compile errors...

// class A { public: int data; virtual int GetData(){return data;} };
typedef struct A { void**vtable; int data;} A;
int AGetData(A*this){ return this->data; }
void * Avtable[] = { (void*)AGetData };
A * newA() { A*res = malloc(sizeof(A)); res->vtable = Avtable; return res; }

// class B : public class A { public: int moredata; virtual int GetData(){return data+1;} }
typedef struct B { void**vtable; int data; int moredata; } B;
int BGetData(B*this){ return this->data + 1; }
void * Bvtable[] = { (void*)BGetData };
B * newB() { B*res = malloc(sizeof(B)); res->vtable = Bvtable; return res; }

// int temp = ptr->GetData();
int temp = ((int(*)())ptr->vtable[0])();

Then a dynamic cast is something like:

// A * ptr = new B();
A * ptr = (A*) newB();
// B * aB = dynamic_cast<B>(ptr);
B * aB = ( ptr->vtable == Bvtable ? (B*) aB : (B*) 0 );

if you are using inline coding in single page and not using oops than go with this full example, it will sure help

//connect to the db
$dbh = new PDO('mysql:host=localhost;dbname=mydb', dbuser, dbpw); 

//build the query
$query="SELECT field1, field2
FROM ubertable
WHERE field1 > 6969";

//execute the query
$data = $dbh->query($query);
//convert result resource to array
$result = $data->fetchAll(PDO::FETCH_ASSOC);

//view the entire array (for testing)
print_r($result);

//display array elements
foreach($result as $output) {
echo output[field1] . " " . output[field1] . "<br />";
}

Simply like that :

<a id="myLink" onclick="alert('link click');">LINK 1</a>
<a id="myLink2" onclick="document.getElementById('myLink').click()">Click link 1</a>

or at page load :

<body onload="document.getElementById('myLink').click()">
...
<a id="myLink" onclick="alert('link click');">LINK 1</a>
...
</body>

On Websphere Application Server, in the same situation, it helped deleting the Temp folders while the server was stopped.

I ran into the situation when the package of the service changed.

function check(selId) {
  var sel = document.getElementById(selId);
  var dropDown_sel = sel.options[sel.selectedIndex].text;
  if (dropDown_sel != "none") {

           state=1;

     //state is a Global variable initially it is set to 0
  } 
}


function checkstatevalue() {
      if (state==1) {
           return 1;
      } 
      return false;
    }

and html is for example

<form name="droptest" onSubmit="return checkstatevalue()">

<select id='Sel1' onchange='check("Sel1");'>
  <option value='junaid'>Junaid</option>
  <option value='none'>none</option>
  <option value='ali'>Ali</option>
</select>

</form>

Now when submitting a form first check what is the value of state if it is 0 it means that no item has been selected.

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

I have a default my-default.ini file in the root and there is one server configuration:

[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

So that does not tell me the path.

The best way is to connect to the database and run this query:

SHOW VARIABLES WHERE Variable_Name LIKE "%dir" ;

Here's the result of that:

basedir                     C:\Program Files (x86)\MySQL\MySQL Server 5.6\
character_sets_dir          C:\Program Files (x86)\MySQL\MySQL Server 5.6\share\charsets\

datadir                     C:\ProgramData\MySQL\MySQL Server 5.6\Data\
innodb_data_home_dir    
innodb_log_group_home_dir   .\
lc_messages_dir             C:\Program Files (x86)\MySQL\MySQL Server 5.6\share\

tmpdir                      C:\Windows\SERVIC~2\NETWOR~1\AppData\Local\Temp

If you want to see all the parameters configured for the database execute this:

SHOW VARIABLES;

The storage_engine variable will tell you if you're using InnoDb or MyISAM.

It's not so much the prime numbers themselves that are important, but the algorithms that work with primes. In particular, finding the factors of a number (any number).

As you know, any number has at least two factors. Prime numbers have the unique property in that they have exactly two factors: 1 and themselves.

The reason factoring is so important is mathematicians and computer scientists don't know how to factor a number without simply trying every possible combination. That is, first try dividing by 2, then by 3, then by 4, and so forth. If you try to factor a prime number--especially a very large one--you'll have to try (essentially) every possible number between 2 and that large prime number. Even on the fastest computers, it will take years (even centuries) to factor the kinds of prime numbers used in cryptography.

It is the fact that we don't know how to efficiently factor a large number that gives cryptographic algorithms their strength. If, one day, someone figures out how to do it, all the cryptographic algorithms we currently use will become obsolete. This remains an open area of research.

Unions are used when you want to model structs defined by hardware, devices or network protocols, or when you're creating a large number of objects and want to save space. You really don't need them 95% of the time though, stick with easy-to-debug code.

I don't think there's any need of writing this much big codes.

I had everything set up, but still couldn't see proper error pages for status code 500 on our staging server, despite the fact everything worked fine on local development servers.

I found this blog post from Rick Strahl that helped me.

I needed to add Response.TrySkipIisCustomErrors = true; to my custom error handling code.

In my case, the view was not viewed in xib. in xib the View was size = none (4th tab right hand). I set size to Freeform and reload xCode. view was appealed and I set the proper link to View.

I had this problem today. I fixed it being being explict about my require

gem 'uglifier', '>= 1.0.3', require: 'uglifier'

I had mine still in the assets group.

One option would be to put all the code in the loop inside a Sub and then just return from that Sub when you want to "continue".

Not perfect, but I think it would be less confusing that the extra loop.

You can do this by just changing the html. Here's an example:

<hmtl>
  <head>
    <title>Some title</title>
  </head>
  <body> 
  <map name="navigatemap">
    <area shape="rect"  
          coords="166,4,319,41" 
          href="WII.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverWII).png'" 
    />
    <area shape="rect"
          coords="330,4,483,41" 
          href="OT.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOT).png'" 
    />

    <area shape="rect" 
          coords="491,3,645,41" 
          href="OP.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOP).png'" 
   />
  </map> 

  <img src="Assets/NavigationBar(OnHome).png" 
     name="navbar" 
     usemap="#navigatemap" />
  </body>

target.Value will give you a Variant type

target.Value2 will give you a Variant type as well but a Date is coerced to a Double

target.Text attempts to coerce to a String and will fail if the underlying Variant is not coercable to a String type

The safest thing to do is something like

Dim v As Variant
v = target.Value 'but if you don't want to handle date types use Value2

And check the type of the variant using VBA.VarType(v) before you attempt an explicit coercion.

For other people coming upon this post on google. There are 2 options, either merging or rebasing your branch. Both works differently, but have similar outcomes.

The accepted answer is a rebase. This will take all the commits done to our-team and then apply the commits done to featurex, prompting you to merge them as needed.

One bit caveat of rebasing is that you lose/rewrite your branch history, essentially telling git that your branch did not began at commit 123abc but at commit 456cde. This will cause problems for other people working on the branch, and some remote tools will complain about it. If you are sure about what you are doing though, that's what the --force flag is for.

What other posters are suggesting is a merge. This will take the featurex branch, with whatever state it has and try to merge it with the current state of our-team, prompting you to do one, big, merge commit and fix all the merge errors before pushing to our-team. The difference is that you are applying your featurex commits before the our-team new commits and then fixing the differences. You also do not rewrite history, instead adding one commit to it instead of rewriting those that came before.

Both options are valid and can work in tandem. What is usually (by that I mean, if you are using widespread tools and methodology such as git-flow) done for a feature branch is to merge it into the main branch, often going through a merge-request, and solve all the conflicts that arise into one (or multiple) merge commits.

Rebasing is an interesting option, that may help you fix your branch before eventually going through a merge, and ease the pain of having to do one big merge commit.

This post has already a very good answer by "Community wiki" and I also recommend to look at Rick Strahl's Web Blog, there are many good posts about WCF Rest like this.

I used both to get this kind of MyService-service... Then I can use the REST-interface from jQuery or SOAP from Java.

This is from my Web.Config:

<system.serviceModel>
 <services>
  <service name="MyService" behaviorConfiguration="MyServiceBehavior">
   <endpoint name="rest" address="" binding="webHttpBinding" contract="MyService" behaviorConfiguration="restBehavior"/>
   <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="MyService"/>
   <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="MyService"/>
  </service>
 </services>
 <behaviors>
  <serviceBehaviors>
   <behavior name="MyServiceBehavior">
    <serviceMetadata httpGetEnabled="true"/>
    <serviceDebug includeExceptionDetailInFaults="true" />
   </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
   <behavior name="restBehavior">
    <webHttp/>
   </behavior>
  </endpointBehaviors>
 </behaviors>
</system.serviceModel>

And this is my service-class (.svc-codebehind, no interfaces required):

    /// <summary> MyService documentation here ;) </summary>
[ServiceContract(Name = "MyService", Namespace = "http://myservice/", SessionMode = SessionMode.NotAllowed)]
//[ServiceKnownType(typeof (IList<MyDataContractTypes>))]
[ServiceBehavior(Name = "MyService", Namespace = "http://myservice/")]
public class MyService
{
    [OperationContract(Name = "MyResource1")]
    [WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "MyXmlResource/{key}")]
    public string MyResource1(string key)
    {
        return "Test: " + key;
    }

    [OperationContract(Name = "MyResource2")]
    [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource/{key}")]
    public string MyResource2(string key)
    {
        return "Test: " + key;
    }
}

Actually I use only Json or Xml but those both are here for a demo purpose. Those are GET-requests to get data. To insert data I would use method with attributes:

[OperationContract(Name = "MyResourceSave")]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource")]
public string MyResourceSave(string thing){
    //...

There are two ways to approach this problem: numerically and symbolically.

To solve it numerically, you have to first encode it as a "runnable" function - stick a value in, get a value out. For example,

def my_function(x):
    return 2*x + 6

It is quite possible to parse a string to automatically create such a function; say you parse 2x + 6 into a list, [6, 2] (where the list index corresponds to the power of x - so 6*x^0 + 2*x^1). Then:

def makePoly(arr):
    def fn(x):
        return sum(c*x**p for p,c in enumerate(arr))
    return fn

my_func = makePoly([6, 2])
my_func(3)    # returns 12

You then need another function which repeatedly plugs an x-value into your function, looks at the difference between the result and what it wants to find, and tweaks its x-value to (hopefully) minimize the difference.

def dx(fn, x, delta=0.001):
    return (fn(x+delta) - fn(x))/delta

def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
    for tries in xrange(maxtries):
        err = fn(x) - value
        if abs(err) < maxerr:
            return x
        slope = dx(fn, x)
        x -= err/slope
    raise ValueError('no solution found')

There are lots of potential problems here - finding a good starting x-value, assuming that the function actually has a solution (ie there are no real-valued answers to x^2 + 2 = 0), hitting the limits of computational accuracy, etc. But in this case, the error minimization function is suitable and we get a good result:

solve(my_func, 16)    # returns (x =) 5.000000000000496

Note that this solution is not absolutely, exactly correct. If you need it to be perfect, or if you want to try solving families of equations analytically, you have to turn to a more complicated beast: a symbolic solver.

A symbolic solver, like Mathematica or Maple, is an expert system with a lot of built-in rules ("knowledge") about algebra, calculus, etc; it "knows" that the derivative of sin is cos, that the derivative of kx^p is kpx^(p-1), and so on. When you give it an equation, it tries to find a path, a set of rule-applications, from where it is (the equation) to where you want to be (the simplest possible form of the equation, which is hopefully the solution).

Your example equation is quite simple; a symbolic solution might look like:

=> LHS([6, 2]) RHS([16])

# rule: pull all coefficients into LHS
LHS, RHS = [lh-rh for lh,rh in izip_longest(LHS, RHS, 0)], [0]

=> LHS([-10,2]) RHS([0])

# rule: solve first-degree poly
if RHS==[0] and len(LHS)==2:
    LHS, RHS = [0,1], [-LHS[0]/LHS[1]]

=> LHS([0,1]) RHS([5])

and there is your solution: x = 5.

I hope this gives the flavor of the idea; the details of implementation (finding a good, complete set of rules and deciding when each rule should be applied) can easily consume many man-years of effort.

When you import lib, you're importing the package. The only file to get evaluated and run in this case is the 0 byte __init__.py in the lib directory.

If you want access to your function, you can do something like this from lib.mod1 import mod1 and then run the mod12 function like so mod1.mod12().

If you want to be able to access mod1 when you import lib, you need to put an import mod1 inside the __init__.py file inside the lib directory.

If you are writing portable code, the answer is "you can't tell", the good news is that you don't need to. Your protocol should involve writing the size as (eg) "8 octets, big-endian format" (Ideally with a check that the actual size fits in 8 octets.)

Even if you don't control the server, you can still see the error messages by adding the following line to the Web.config file in your project (bewlow <system.web>):

<customErrors mode="off" />

1. In the project navigator, select your project.

2. Select your target.

3. Select the "Build Phases" tab.

4. expander. Click the + button.

5. Select your framework.

6. (optional) Drag and drop the added framework to the "Frameworks" group.

   

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.

You can create a Unicode string multiple ways:

>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'

But the real reason is to represent something like this (translation here):

>>> val = u'???????????? ? ?????????????'
>>> val
u'\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u0430\u0446\u0438\u0435\u0439'
>>> print val
???????????? ? ?????????????

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.

There are other symbols you will see, such as the "raw" symbol r for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.

>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'

Unicode and non-Unicode strings can be equal on Python 2:

>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True

but not on Python 3:

>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False

When autocomplete changes a value, it fires a autocompletechange event, not the change event

$(document).ready(function () {
    $('#tags').on('autocompletechange change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
});

Demo: Fiddle

Another solution is to use select event, because the change event is triggered only when the input is blurred

$(document).ready(function () {
    $('#tags').on('change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
    $('#tags').on('autocompleteselect', function (e, ui) {
        $('#tagsname').html('You selected: ' + ui.item.value);
    });
});

Demo: Fiddle

You can use the standard Python idiom, vars():

for attr, value in vars(k).items():
    print(attr, '=', value)

This is the way to iterate on this array:

foreach($hotels as $row) {
       foreach($row['rooms'] as $k) {
             echo $k['boards']['board_id'];
             echo $k['boards']['price'];
       }
}

You want to iterate on the hotels and the rooms (the ones with numeric indexes), because those seem to be the "collections" in this case. The other arrays only hold and group properties.

Your program crashes because it used memory that does not belong to you. It may be used by someone else or not - if you are lucky you crash, if not the problem may stay hidden for a long time and come back and bite you later.

As far as malloc/free implementation goes - entire books are devoted to the topic. Basically the allocator would get bigger chunks of memory from the OS and manage them for you. Some of the problems an allocator must address are:

• How to get new memory
• How to store it - ( list or other structure, multiple lists for memory chunks of different size, and so on )
• What to do if the user requests more memory than currently available ( request more memory from OS, join some of the existing blocks, how to join them exactly, ... )
• What to do when the user frees memory
• Debug allocators may give you bigger chunk that you requested and fill it some byte pattern, when you free the memory the allocator can check if wrote outside of the block ( which is probably happening in your case) ...

Create a linked server to the source server. The easiest way is to right click "Linked Servers" in Management Studio; it's under Management -> Server Objects.

Then you can copy the table using a 4-part name, server.database.schema.table:

select  *
into    DbName.dbo.NewTable
from    LinkedServer.DbName.dbo.OldTable

This will both create the new table with the same structure as the original one and copy the data over.

A query string is an array of parameters sent to a web page.

This url: http://page.asp?x=1&y=hello

Request.QueryString[0] is the same as 
Request.QueryString["x"] and holds a string value "1"

Request.QueryString[1] is the same as 
Request.QueryString["y"] and holds a string value "hello"

Try tagging it with:

In addition to the above comments, I would like to add few points about Views.

1. Views can be used to hide complexity. Imagine a scenario where 5 people are working on a project but only one of them is too good with database stuff like complex joins. In such scenario, he can create Views which can be easily queried by other team members as they are querying any single table.
2. Security can be easily implemented by Views. Suppose we a Table Employee which contains sensitive columns like Salary, SSN number. These columns are not supposed to be visible to the users who are not authorized to view them. In such case, we can create a View selecting the columns in a table which doesn't require any authorization like Name, Age etc, without exposing sensitive columns (like Salary etc. we mentioned before). Now we can remove permission to directly query the table Employee and just keep the read permission on the View. In this way, we can implement security using Views.

I had same issue with F-secure, DeepGuard was blocking the Docker service. My solution was:

Open F-secure client and click "Tasks"

Choose "Allow a program to start"

Choose from list "com.docker.service" and press "Remove"

After that restart Docker client and try to apply for file share.

Also very good troubleshoot guide here: Error: A firewall is blocking file sharing between Windows and the containers

I want to add a little bit of improvement from an almost excellent answer from user @thyago stall above. In Python, we can do one line swapping. The selection_sort below also has been fixed by just swapping the current element with the minimum element at the right side.

In insertion sort we will run the outer loop from the second element and do an inner loop on the left side of the current element, shifting the smaller elements to the left.

def insertion_sort(arr):
    i = 1
    while i < len(arr):
        for j in range(i):
            if arr[i] < arr[j]:
                arr[i], arr[j] = arr[j], arr[i]
    i += 1

In selection sort, we also run the outer loop but instead of starting from the second element, we start from the first element. Then inner loop will loop the current + i element to the end of array to find the minimum element and we will swapped with the current index.

def selection_sort(arr):
    i = 0
    while i < len(arr):
        min_idx = i
        for j in range(i + 1, len(arr)):
            if arr[min_idx] > arr[j]:
                min_idx = j
        arr[i], arr[min_idx] = arr[min_idx], arr[i]
    i += 1

I had these choices:

-----------------------------------------------
*  1           /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java
 + 2           /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
   3           /home/ec2-user/local/java/jre1.7.0_25/bin/java

When I chose 3, it didn't work. When I chose 2, it did work.

I've run into that same issue as well. It's because you're closing your connection to the socket, but not the socket itself. The socket can enter a TIME_WAIT state (to ensure all data has been transmitted, TCP guarantees delivery if possible) and take up to 4 minutes to release.

or, for a REALLY detailed/technical explanation, check this link

It's certainly annoying, but it's not a bug. See the comment from @Vereb on this answer below on the use of SO_REUSEADDR.

You can use the static/class constructor to initialize your dictionary:

public static class ErrorCode
{
    public const IDictionary<string, string> ErrorCodeDic;
    public static ErrorCode()
    {
        ErrorCodeDic = new Dictionary<string, string>()
            { {"1", "User name or password problem"} };
    }
}

If you're trying to print() Unicode, and getting ascii codec errors, check out this page, the TLDR of which is do export PYTHONIOENCODING=UTF-8 before firing up python (this variable controls what sequence of bytes the console tries to encode your string data as). Internally, Python3 uses UTF-8 by default (see the Unicode HOWTO) so that's not the problem; you can just put Unicode in strings, as seen in the other answers and comments. It's when you try and get this data out to your console that the problem happens. Python thinks your console can only handle ascii. Some of the other answers say, "Write it to a file, first" but note they specify the encoding (UTF-8) for doing so (so, Python doesn't change anything in writing), and then use a method for reading the file that just spits out the bytes without any regard for encoding, which is why that works.

In Pyspark you can simply specify each condition separately:

val Lead_all = Leads.join(Utm_Master,  
    (Leaddetails.LeadSource == Utm_Master.LeadSource) &
    (Leaddetails.Utm_Source == Utm_Master.Utm_Source) &
    (Leaddetails.Utm_Medium == Utm_Master.Utm_Medium) &
    (Leaddetails.Utm_Campaign == Utm_Master.Utm_Campaign))

Just be sure to use operators and parenthesis correctly.

The below code works for me -:

jQuery('[id^=select_] > option').each(function(){
        if (this.text.toLowerCase()=='text'){
            jQuery('[id^=select_]').val(this.value);
        }
});

jQuery('[id^=select_]') - This allows you to select drop down where ID of the drop down starts from select_

Hope the above helps!

There seems to be another (rather hacky) way to reuse the router-outlet in one template. This answer is intendend for informational purposes only and the techniques used here should probably not be used in production.

https://stackblitz.com/edit/router-outlet-twice-with-events

The router-outlet is wrapped by an ng-template. The template is updated by listening to events of the router. On every event the template is swapped and re-swapped with an empty placeholder. Without this "swapping" the template would not be updated.

This most definetly is not a recommended approach though, since the whole swapping of two templates seems a bit hacky.

in the controller:

  ngOnInit() {
    this.router.events.subscribe((routerEvent: Event) => {
      console.log(routerEvent);
      this.myTemplateRef = this.trigger;
      setTimeout(() => {
        this.myTemplateRef = this.template;
      }, 0);
    });
  }

in the template:

<div class="would-be-visible-on-mobile-only">
  This would be the mobile-layout with a router-outlet (inside a template): 
  <br>
  <ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>

<hr>

<div class="would-be-visible-on-desktop-only">
  This would be the desktop-layout with a router-outlet (inside a template): 
  <br>
  <ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>

<ng-template #template>
    <br>
    This is my counter: {{counter}}
    inside the template, the router-outlet should follow
    <router-outlet>
    </router-outlet>
</ng-template>

<ng-template #trigger>
  template to trigger changes...
</ng-template>

If you are sure that your value is not null you can use third option which is

String str3 = b.toString();

and its code looks like

public String toString() {
    return value ? "true" : "false";
}

If you want to be null-safe use String.valueOf(b) which code looks like

public static String valueOf(Object obj) {
    return (obj == null) ? "null" : obj.toString();
}

so as you see it will first test for null and later invoke toString() method on your object.

Calling Boolean.toString(b) will invoke

public static String toString(boolean b) {
    return b ? "true" : "false";
}

which is little slower than b.toString() since JVM needs to first unbox Boolean to boolean which will be passed as argument to Boolean.toString(...), while b.toString() reuses private boolean value field in Boolean object which holds its state.

This should help you.

As integers are comparable we can use the following one liner in:

List<Integer> ints = Stream.of(22,44,11,66,33,55).collect(Collectors.toList());
Integer max = ints.stream().mapToInt(i->i).max().orElseThrow(NoSuchElementException::new); //66
Integer min = ints.stream().mapToInt(i->i).min().orElseThrow(NoSuchElementException::new); //11

Another point to note is we cannot use Funtion.identity() in place of i->i as mapToInt expects ToIntFunction which is a completely different interface and is not related to Function. Moreover this interface has only one method applyAsInt and no identity() method.

The simple answer is that arrays are ALWAYS passed by reference and the int arg[] simply lets the compiler know to expect an array

Use pd.to_numeric with errors='coerce'

# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

0    1
1    2
2    3
3    4
4    .
dtype: object

pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
dtype: float64

If you need the NaNs filled in, use Series.fillna.

pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')

0    1
1    2
2    3
3    4
4    0
dtype: float64

Note, downcast='infer' will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.

From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use

pd.__version__
# '0.24.1'

pd.to_numeric(s, errors='coerce').astype('Int32')

0      1
1      2
2      3
3      4
4    NaN
dtype: Int32

There are other options to choose from as well, read the docs for more.

Extension for DataFrames

If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply.

# Setup.
np.random.seed(0)
df = pd.DataFrame({
    'A' : np.random.choice(10, 5), 
    'C' : np.random.choice(10, 5), 
    'B' : ['1', '###', '...', 50, '234'], 
    'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df

   A    B  C    D
0  5    1  9   23
1  0  ###  3    1
2  3  ...  5  ...
3  3   50  2  268
4  7  234  4   $$

df.dtypes

A     int64
B    object
C     int64
D    object
dtype: object

df2 = df.apply(pd.to_numeric, errors='coerce')
df2

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

df2.dtypes

A      int64
B    float64
C      int64
D    float64
dtype: object

You can also do this with DataFrame.transform; although my tests indicate this is marginally slower:

df.transform(pd.to_numeric, errors='coerce')

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric on the non-numeric columns only.

df.dtypes.eq(object)

A    False
B     True
C    False
D     True
dtype: bool

cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')

df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
#     df[c] = pd.to_numeric(df[c], errors='coerce')

df

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

Applying pd.to_numeric along the columns (i.e., axis=0, the default) should be slightly faster for long DataFrames.

I implemented this in java and ran a unit test (source below). None of the above solutions work. This code passes the unit test. If anyone finds a unit test that does not pass, please let me know.

Code: NOTE: nearlyEqual(double,double) returns true if the two numbers are very close.

/*
 * @return integer code for which side of the line ab c is on.  1 means
 * left turn, -1 means right turn.  Returns
 * 0 if all three are on a line
 */
public static int findSide(
        double ax, double ay, 
        double bx, double by,
        double cx, double cy) {
    if (nearlyEqual(bx-ax,0)) { // vertical line
        if (cx < bx) {
            return by > ay ? 1 : -1;
        }
        if (cx > bx) {
            return by > ay ? -1 : 1;
        } 
        return 0;
    }
    if (nearlyEqual(by-ay,0)) { // horizontal line
        if (cy < by) {
            return bx > ax ? -1 : 1;
        }
        if (cy > by) {
            return bx > ax ? 1 : -1;
        } 
        return 0;
    }
    double slope = (by - ay) / (bx - ax);
    double yIntercept = ay - ax * slope;
    double cSolution = (slope*cx) + yIntercept;
    if (slope != 0) {
        if (cy > cSolution) {
            return bx > ax ? 1 : -1;
        }
        if (cy < cSolution) {
            return bx > ax ? -1 : 1;
        }
        return 0;
    }
    return 0;
}

Here's the unit test:

@Test public void testFindSide() {
    assertTrue("1", 1 == Utility.findSide(1, 0, 0, 0, -1, -1));
    assertTrue("1.1", 1 == Utility.findSide(25, 0, 0, 0, -1, -14));
    assertTrue("1.2", 1 == Utility.findSide(25, 20, 0, 20, -1, 6));
    assertTrue("1.3", 1 == Utility.findSide(24, 20, -1, 20, -2, 6));

    assertTrue("-1", -1 == Utility.findSide(1, 0, 0, 0, 1, 1));
    assertTrue("-1.1", -1 == Utility.findSide(12, 0, 0, 0, 2, 1));
    assertTrue("-1.2", -1 == Utility.findSide(-25, 0, 0, 0, -1, -14));
    assertTrue("-1.3", -1 == Utility.findSide(1, 0.5, 0, 0, 1, 1));

    assertTrue("2.1", -1 == Utility.findSide(0,5, 1,10, 10,20));
    assertTrue("2.2", 1 == Utility.findSide(0,9.1, 1,10, 10,20));
    assertTrue("2.3", -1 == Utility.findSide(0,5, 1,10, 20,10));
    assertTrue("2.4", -1 == Utility.findSide(0,9.1, 1,10, 20,10));

    assertTrue("vertical 1", 1 == Utility.findSide(1,1, 1,10, 0,0));
    assertTrue("vertical 2", -1 == Utility.findSide(1,10, 1,1, 0,0));
    assertTrue("vertical 3", -1 == Utility.findSide(1,1, 1,10, 5,0));
    assertTrue("vertical 3", 1 == Utility.findSide(1,10, 1,1, 5,0));

    assertTrue("horizontal 1", 1 == Utility.findSide(1,-1, 10,-1, 0,0));
    assertTrue("horizontal 2", -1 == Utility.findSide(10,-1, 1,-1, 0,0));
    assertTrue("horizontal 3", -1 == Utility.findSide(1,-1, 10,-1, 0,-9));
    assertTrue("horizontal 4", 1 == Utility.findSide(10,-1, 1,-1, 0,-9));

    assertTrue("positive slope 1", 1 == Utility.findSide(0,0, 10,10, 1,2));
    assertTrue("positive slope 2", -1 == Utility.findSide(10,10, 0,0, 1,2));
    assertTrue("positive slope 3", -1 == Utility.findSide(0,0, 10,10, 1,0));
    assertTrue("positive slope 4", 1 == Utility.findSide(10,10, 0,0, 1,0));

    assertTrue("negative slope 1", -1 == Utility.findSide(0,0, -10,10, 1,2));
    assertTrue("negative slope 2", -1 == Utility.findSide(0,0, -10,10, 1,2));
    assertTrue("negative slope 3", 1 == Utility.findSide(0,0, -10,10, -1,-2));
    assertTrue("negative slope 4", -1 == Utility.findSide(-10,10, 0,0, -1,-2));

    assertTrue("0", 0 == Utility.findSide(1, 0, 0, 0, -1, 0));
    assertTrue("1", 0 == Utility.findSide(0,0, 0, 0, 0, 0));
    assertTrue("2", 0 == Utility.findSide(0,0, 0,1, 0,2));
    assertTrue("3", 0 == Utility.findSide(0,0, 2,0, 1,0));
    assertTrue("4", 0 == Utility.findSide(1, -2, 0, 0, -1, 2));
}

You can use this extension method for enumerables containing more complex types:

IEnumerable<Foo> distinctList = sourceList.DistinctBy(x => x.FooName);

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(
    this IEnumerable<TSource> source,
    Func<TSource, TKey> keySelector)
{
    var knownKeys = new HashSet<TKey>();
    return source.Where(element => knownKeys.Add(keySelector(element)));
}

You just need to put "group(1)" instead of "group()" in the following line and the return will be the one you expected:

System.out.println("I found the text: " + matcher.group(**1**).toString());

Yes to the first question and no to the second question; it's a virtual machine. Your problems are probably related to unspecified changes in library implementation between versions. Although it could be, say, a race condition.

There are some hoops the VM has to go through. Notably references are treated in class files as if they took the same space as ints on the stack. double and long take up two reference slots. For instance fields, there's some rearrangement the VM usually goes through anyway. This is all done (relatively) transparently.

Also some 64-bit JVMs use "compressed oops". Because data is aligned to around every 8 or 16 bytes, three or four bits of the address are useless (although a "mark" bit may be stolen for some algorithms). This allows 32-bit address data (therefore using half as much bandwidth, and therefore faster) to use heap sizes of 35- or 36-bits on a 64-bit platform.

I've wanted to do this quite a lot. This hack is very similar to rlotun's suggestion, but it's a one-liner, which is important to me:

blah = 1
blah_name = [ k for k,v in locals().iteritems() if v is blah][0]

Python 3+

blah = 1
blah_name = [ k for k,v in locals().items() if v is blah][0]

Instead of rand(), use newid(), which is recalculated for each row in the result. The usual way is to use the modulo of the checksum. Note that checksum(newid()) can produce -2,147,483,648 and cause integer overflow on abs(), so we need to use modulo on the checksum return value before converting it to absolute value.

UPDATE CattleProds
SET    SheepTherapy = abs(checksum(NewId()) % 10000)
WHERE  SheepTherapy IS NULL

This generates a random number between 0 and 9999.

Old question but I came up with a definitive answer with an example. Can't hurt to keep questions fresh as I had this same problem and didn't find a clear answer. The key is to make sure you have numpy imported, and then run the isinstance bool. While this may seem simple, if you are doing some computations across different data types, this small check can serve as a quick test before your start some numpy vectorized operation.

Add XAttribute in the constructor of the XElement, like

new XElement("Conn", new XAttribute("Server", comboBox1.Text));

You can also add multiple attributes or elements via the constructor

new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));

or you can use the Add-Method of the XElement to add attributes

XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

Try following code;

DropDownList1.Items.Add(new ListItem(txt_box1.Text));

Of Course, abstract class can have a constructor.Generally class constructor is used to initialise fields.So, an abstract class constructor is used to initialise fields of the abstract class. You would provide a constructor for an abstract class if you want to initialise certain fields of the abstract class before the instantiation of a child-class takes place. An abstract class constructor can also be used to execute code that is relevant for every child class. This prevents code duplication.

We cannot create an instance of an abstract class,But we can create instances of classes those are derived from the abstract class. So, when an instance of derived class is created, the parent abstract class constructor is automatically called.

Reference :This Article

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

When and where to use \\\" instead. OK if you are like me you will feel just as silly as I did when I realized what I was doing after I found this thread.

If you're making a .json text file/stream and importing the data from there then the main stream answer of just one backslash before the double quotes:\" is the one you're looking for.

However if you're like me and you're trying to get the w3schools.com "Tryit Editor" to have a double quotes in the output of the JSON.parse(text), then the one you're looking for is the triple backslash double quotes \\\". This is because you're building your text string within an HTML <script> block, and the first double backslash inserts a single backslash into the string variable then the following backslash double quote inserts the double quote into the string so that the resulting script string contains the \" from the standard answer and the JSON parser will parse this as just the double quotes.

<script>
  var text="{";
  text += '"quip":"\\\"If nobody is listening, then you\'re likely talking to the wrong audience.\\\""';
  text += "}";
  var obj=JSON.parse(text);
</script>

+1: since it's a JavaScript text string, a double backslash double quote \\" would work too; because the double quote does not need escaped within a single quoted string eg '\"' and '"' result in the same JS string.
