Programs & Examples On #Lazy sequences

try this...

$("#yourdropdownid option:selected").val();

Use SHOW OPEN TABLES: http://dev.mysql.com/doc/refman/5.1/en/show-open-tables.html

You can do something like this

SHOW OPEN TABLES WHERE `Table` LIKE '%[TABLE_NAME]%' AND `Database` LIKE '[DBNAME]' AND In_use > 0;

to check any locked tables in a database.

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

If this batch file is something you want to run as scheduled or always; you can use windows schedule tool and it doesn't opens up in a window when it starts the batch file.

To open Task Scheduler:

• Start -> Run/Search -> 'cmd'
• Type taskschd.msc -> enter

From the right side, click Create Basic Task and follow the menus.

Hope this helps.

if you want to upgrade pip by proxy, can use (for example in Windows):

python -m pip --proxy http://proxy_user:proxy_password@proxy_hostname:proxy_port insta
ll --upgrade pip

@wdavo is correct. The same is also true for functions.

If you override a base function, like Update, then in your subclass you need:

new void Update()
{
  //do stufff
}

Without the new at the start of the function decleration you will get the warning flag.

I've found Waldo!

How I've done it

First, I'm filtering out all colours that aren't red

waldo = Import["http://www.findwaldo.com/fankit/graphics/IntlManOfLiterature/Scenes/DepartmentStore.jpg"];
red = Fold[ImageSubtract, #[[1]], Rest[#]] &@ColorSeparate[waldo];

Next, I'm calculating the correlation of this image with a simple black and white pattern to find the red and white transitions in the shirt.

corr = ImageCorrelate[red, 
   Image@Join[ConstantArray[1, {2, 4}], ConstantArray[0, {2, 4}]], 
   NormalizedSquaredEuclideanDistance];

I use Binarize to pick out the pixels in the image with a sufficiently high correlation and draw white circle around them to emphasize them using Dilation

pos = Dilation[ColorNegate[Binarize[corr, .12]], DiskMatrix[30]];

I had to play around a little with the level. If the level is too high, too many false positives are picked out.

Finally I'm combining this result with the original image to get the result above

found = ImageMultiply[waldo, ImageAdd[ColorConvert[pos, "GrayLevel"], .5]]

With SQL server you can just use a CTE instead of IF/THEN logic to make it easy to map from your existing queries and change the number of involved queries;

WITH cte AS (
    SELECT product,price,1 a FROM table1 WHERE project=1   UNION ALL
    SELECT product,price,2 a FROM table1 WHERE customer=2  UNION ALL
    SELECT product,price,3 a FROM table1 WHERE company=3
)
SELECT TOP 1 WITH TIES product,price FROM cte ORDER BY a;

An SQLfiddle to test with.

Alternately, you can combine it all into one SELECT to simplify it for the optimizer;

SELECT TOP 1 WITH TIES product,price FROM table1 
WHERE project=1 OR customer=2 OR company=3
ORDER BY CASE WHEN project=1  THEN 1 
              WHEN customer=2 THEN 2
              WHEN company=3  THEN 3 END;

Another SQLfiddle.

I comment out //api 'com.google.android.gms:play-services-ads:15.0.1' it worked for me after sync

Remove the dot and import absolute_import in the beginning of your file

from __future__ import absolute_import

from p_02_paying_debt_off_in_a_year import compute_balance_after

Andy gave me some good pointers, but I wanted to do it in an even cleaner way. Not to mention that with the 2>&1 >> method PowerShell complained to me about the log file being accessed by another process, i.e. both stderr and stdout trying to lock the file for access, I guess. So here's how I worked it around.

First let's generate a nice filename, but that's really just for being pedantic:

$name = "sync_common"
$currdate = get-date -f yyyy-MM-dd
$logfile = "c:\scripts\$name\log\$name-$currdate.txt"

And here's where the trick begins:

start-transcript -append -path $logfile

write-output "starting sync"
robocopy /mir /copyall S:\common \\10.0.0.2\common 2>&1 | Write-Output
some_other.exe /exeparams 2>&1 | Write-Output
...
write-output "ending sync"

stop-transcript

With start-transcript and stop-transcript you can redirect ALL output of PowerShell commands to a single file, but it doesn't work correctly with external commands. So let's just redirect all the output of those to the stdout of PS and let transcript do the rest.

In fact, I have no idea why the MS engineers say they haven't fixed this yet "due to the high cost and technical complexities involved" when it can be worked around in such a simple way.

Either way, running every single command with start-process is a huge clutter IMHO, but with this method, all you gotta do is append the 2>&1 | Write-Output code to each line which runs external commands.

There is no official, universal, convention for naming JavaScript files.

There are some various options:

• scriptName.js
• script-name.js
• script_name.js

are all valid naming conventions, however I prefer the jQuery suggested naming convention (for jQuery plugins, although it works for any JS)

• jquery.pluginname.js

The beauty to this naming convention is that it explicitly describes the global namespace pollution being added.

• foo.js adds window.foo
• foo.bar.js adds window.foo.bar

Because I left out versioning: it should come after the full name, preferably separated by a hyphen, with periods between major and minor versions:

• foo-1.2.1.js
• foo-1.2.2.js
• ...
• foo-2.1.24.js

alert and notify-send seem to be the same thing. I use notify-send for non-input messages as it doesn't steal focus and I cannot find a way to stop zenity etc. from doing this.

e.g.

# This will display message and then disappear after a delay:
notify-send "job complete"

# This will display message and stay on-screen until clicked:
notify-send -u critical "job complete"

String s = "aaaabbbbcccddddd";
Map<Character, Integer> map = new HashMap<>();

Using one line in Java8

s.chars().forEach(e->map.put((char)e, map.getOrDefault((char)e, 0) + 1));

Just to clarify some of the great answers here, the steps outlined in many of the answers assume that you already have a remote repository somewhere.

Given: an existing git repository, e.g. [email protected]:some-user/full-repo.git, with one or more directories that you wish to pull independently of the rest of the repo, e.g. directories named app1 and app2

Assuming you have a git repository as the above...

Then: you can run steps like the following to pull only specific directories from that larger repo:

mkdir app1
cd app1
git init
git remote add origin [email protected]:some-user/full-repo.git
git config core.sparsecheckout true
echo "app1/" >> .git/info/sparse-checkout
git pull origin master

I had mistakenly thought that the sparse-checkout options had to be set on the original repository, but this is not the case: you define which directories you want locally, prior to pulling from the remote. The remote repo doesn't know or care about your only wanting to track a part of the repo.

Hope this clarification helps someone else.

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));

Simply follow the instructions given here:

Example install:

sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

It installs current stable Node on the current stable Ubuntu. Quantal (12.10) users may need to install the software-properties-common package for the add-apt-repository command to work: sudo apt-get install software-properties-common

As of Node.js v0.10.0, the nodejs package from Chris Lea's repo includes both npm and nodejs-dev.

Don't give sudo apt-get install nodejs npm. Just sudo apt-get install nodejs.

JObject.ContainsKey(string propertyName) has been made as public method in 11.0.1 release

Documentation - https://www.newtonsoft.com/json/help/html/M_Newtonsoft_Json_Linq_JObject_ContainsKey.htm

This is by far the coolest thing I've seen... and when broken down, it's actually pretty simple:

http://blogs.msdn.com/lukeh/archive/2007/04/03/a-ray-tracer-in-c-3-0.aspx

Yes, Javascript always passes by value, but in an array or object, the value is a reference to it, so you can 'change' the contents.

But, I think you already read it on SO; here you have the documentation you want:

http://snook.ca/archives/javascript/javascript_pass

If this is coming from SQL Server Import Wizard, try editing the definition of the column on the Data Source, it is 50 characters by default, but it can be longer.

Data Soruce -> Advanced -> Look at the column that goes in error -> change OutputColumnWidth to 200 and try again.

As @Antonijn stated, you need to execute getTitle method, by adding parentheses:

 string t = obj.getTitle();

But I want to add, that you are doing Java programming in C#. There is concept of properties (pair of get and set methods), which should be used in such cases:

public class Pin
{
    private string _title;

    // you don't need to define empty constructor
    // public Pin() { }

    public string Title 
    {
        get { return _title; }
        set { _title = value; }
    }  
}

And even more, in this case you can ask compiler not only for get and set methods generation, but also for back storage generation, via auto-impelemented property usage:

public class Pin
{
    public string Title { get; set; }
}

And now you don't need to execute method, because properties used like fields:

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

$this->db->where('(a = 1 or a = 2)');

I my case, I had to switch from API 21 to API 19, clean and build and everything was fine again. I am using a Mac and apparently API 21 is not fully supported on Yosemite.

It's not as straightforward as looks. I just run into a similar question, and here is what I got: First, a little background on wikipedia.

Next, in CSS, for paper, they have pt, which is point, or 1/72 inch. So if you want to have the same size of image as on the monitor, first you have to know the DPI/PPI of your monitor (usually 96, as mentioned on the wikipedia article), then convert it to inches, then convert it to points (divide by 72).

But then again, the browsers have all sorts of problems with printable content, for example, if you try to use float css tags, the Gecko-based browsers will cut your images mid page, even if you use page-break-inside: avoid; on your images (see here, in the Mozilla bug tracking system).

There is (much) more about printing from a browser in this article on A List Apart.

Furthermore, you have to deal width "Shrink to Fit" in the print preview, and the various paper sizes and orientations.

So either you just figure out a good image size in inches, I mean points, (7.1" * 72 = 511.2 so width: 511pt; would work for the letter sized paper) regardless of the pixel sizes, or go width percentage widths, and base your image widths on the paper size.

Good luck...

In ruby 2.0 you can now just use %

For example:

    SQL = %{
      SELECT user, name
      FROM users
      WHERE users.id = #{var}
      LIMIT #{var2}
    }

Could find nothing simpler and better than this solution. Also see the doc.

@register.filter
def dictitem(dictionary, key):
    return dictionary.get(key)

But there's a problem (also discussed here) that the returned item is an object and I need to reference a field of this object. Expressions like {{ (schema_dict|dictitem:schema_code).name }} are not supported, so the only solution I found was:

{% with schema=schema_dict|dictitem:schema_code %}
    <p>Selected schema: {{ schema.name }}</p>
{% endwith %}

UPDATE:

@register.filter
def member(obj, name):
    return getattr(obj, name, None)

So no need for a with tag:

{{ schema_dict|dictitem:schema_code|member:'name' }}

They are often used interchangeably in text, but in most standards the distinction is that an argument is an expression passed to a function, where a parameter is a reference declared in a function declaration.

As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.

I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.

SET @sql = '';
SELECT
    @sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
    SELECT
      DISTINCT
        CONCAT(
         'MAX(IF(pa.fieldname = ''',
          fieldname,
          ''', pa.fieldvalue, NULL)) AS ',
          fieldname
        ) as output
    FROM
        product_additional
) as temp;

SET @sql = CONCAT('SELECT p.id
                    , p.name
                    , p.description, ', @sql, ' 
                   FROM product p
                   LEFT JOIN product_additional AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

VB Version (using port 9100 - tested on Zebra ZM400)

Sub PrintZPL(ByVal pIP As String, ByVal psZPL As String)
    Dim lAddress As Net.IPEndPoint
    Dim lSocket As System.Net.Sockets.Socket = Nothing
    Dim lNetStream As System.Net.Sockets.NetworkStream = Nothing
    Dim lBytes As Byte()

    Try
        lAddress = New Net.IPEndPoint(Net.IPAddress.Parse(pIP), 9100)
        lSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, _                       ProtocolType.Tcp)
        lSocket.Connect(lAddress)
        lNetStream = New NetworkStream(lSocket)

        lBytes = System.Text.Encoding.ASCII.GetBytes(psZPL)
        lNetStream.Write(lBytes, 0, lBytes.Length)
    Catch ex As Exception When Not App.Debugging
        Msgbox ex.message & vbnewline & ex.tostring
    Finally
        If Not lNetStream Is Nothing Then
            lNetStream.Close()
        End If
        If Not lSocket Is Nothing Then
            lSocket.Close()
        End If
    End Try
End Sub

you can put everything in a block and easily write any code that you wish in that block just exactly the below code :

@{
        bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
        if (isUserConnected)
        { // meaning that the viewing user has not been saved
            <div>
                <div> click to join us </div>
                <a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
            </div>
        }
    }

it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes

Created a handy function for this..

function findAndRemove(array, property, value) {
  array.forEach(function(result, index) {
    if(result[property] === value) {
      //Remove from array
      array.splice(index, 1);
    }    
  });
}

//Checks countries.result for an object with a property of 'id' whose value is 'AF'
//Then removes it ;p
findAndRemove(countries.results, 'id', 'AF');

You can use setTableId((short)100). I think this was changed in Java 5 so that numeric literals assigned to byte or short and within range for the target are automatically assumed to be the target type. That latest J2ME JVMs are derived from Java 4 though.

I was using Maven in eclipse and I did not want to have an additional copy of the properties file in the root folder. You can do the following in eclipse:

1. Open run dialog (click the little arrow next to the play button and go to run configurations)
2. Go to the "classpath" tab
3. Select the "User Entries" and click the "Advanced" button on the right side.
4. Now select the "Add External folder" radio button.
5. Select the resources folder

No, which is why so many other libraries have their own copy :)

For those who don't want to use HTML agility pack and want to get HtmlDocument from string using native .net code only here is a good article on how to convert string to HtmlDocument

Here is the code block to use

public System.Windows.Forms.HtmlDocument GetHtmlDocument(string html)
        {
            WebBrowser browser = new WebBrowser();
            browser.ScriptErrorsSuppressed = true;
            browser.DocumentText = html;
            browser.Document.OpenNew(true);
            browser.Document.Write(html);
            browser.Refresh();
            return browser.Document;
        }

You could use a map function that allows multiple arguments, as does the fork of multiprocessing found in pathos.

>>> from pathos.multiprocessing import ProcessingPool as Pool
>>> 
>>> def add_and_subtract(x,y):
...   return x+y, x-y
... 
>>> res = Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))
>>> res
[(-5, 5), (-2, 6), (1, 7), (4, 8), (7, 9), (10, 10), (13, 11), (16, 12), (19, 13), (22, 14)]
>>> Pool().map(add_and_subtract, *zip(*res))
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

pathos enables you to easily nest hierarchical parallel maps with multiple inputs, so we can extend our example to demonstrate that.

>>> from pathos.multiprocessing import ThreadingPool as TPool
>>> 
>>> res = TPool().amap(add_and_subtract, *zip(*Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))))
>>> res.get()
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

Even more fun, is to build a nested function that we can pass into the Pool. This is possible because pathos uses dill, which can serialize almost anything in python.

>>> def build_fun_things(f, g):
...   def do_fun_things(x, y):
...     return f(x,y), g(x,y)
...   return do_fun_things
... 
>>> def add(x,y):
...   return x+y
... 
>>> def sub(x,y):
...   return x-y
... 
>>> neato = build_fun_things(add, sub)
>>> 
>>> res = TPool().imap(neato, *zip(*Pool().map(neato, range(0,20,2), range(-5,5,1))))
>>> list(res)
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

If you are not able to go outside of the standard library, however, you will have to do this another way. Your best bet in that case is to use multiprocessing.starmap as seen here: Python multiprocessing pool.map for multiple arguments (noted by @Roberto in the comments on the OP's post)

Get pathos here: https://github.com/uqfoundation

I think the question should be the difference between mutex and binary semaphore.

Mutex = It is a ownership lock mechanism, only the thread who acquire the lock can release the lock.

binary Semaphore = It is more of a signal mechanism, any other higher priority thread if want can signal and take the lock.

To create the datepicker and set the date.

$('.next_date').datepicker({ dateFormat: 'dd-mm-yy'}).datepicker("setDate", new Date());

Since the title suggests wildcard you could also use this:

$(document).ready(function(){_x000D_
  console.log($('[id*=ander]'));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="jander1"></div>_x000D_
<div id="jander2"></div>

This will select the given string anywhere in the id.

You could decide to make use of a templating engine in your project, such as:

• mustache
• underscore.js
• handlebars

If you don't want to include another library, John Resig offers a jQuery solution, similar to the one below.

Browsers and screen readers ignore unrecognized script types:

<script id="hidden-template" type="text/x-custom-template">
    <tr>
        <td>Foo</td>
        <td>Bar</td>
    <tr>
</script>

Using jQuery, adding rows based on the template would resemble:

var template = $('#hidden-template').html();

$('button.addRow').click(function() {
    $('#targetTable').append(template);
});

You mistyped the set command – you missed the backslash after C:. It should be:

C:\>set path=C:\Program Files (x86)\Java\jdk1.7.0\bin

You just have to figure out the millisecond part of the date and subtract it out before comparison, like this:

select * 
from table 
where DATEADD(ms, -DATEPART(ms, date), date) > '2010-07-20 03:21:52'

You have the arguments in the wrong order:

git branch <branch-name> <commit>

and for that, it doesn't matter what branch is checked out; it'll do what you say. (If you omit the commit argument, it defaults to creating a branch at the same place as the current one.)

If you want to check out the new branch as you create it:

git checkout -b <branch> <commit>

with the same behavior if you omit the commit argument.

If you mean you want them back as a string, in that format;

SELECT 
  CONVERT(CHAR(4), date_of_birth, 100) + CONVERT(CHAR(4), date_of_birth, 120) 
FROM customers

Here are the other format options

I'm also struck with this same problem, finally i got simple solution. just added one line to action bar style.

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:textColorPrimary">@color/colorAccent</item>
    <item name="android:colorBackground">@color/colorAppWhite</item>
</style>

"android:colorBackground" is enough to change option menu background

public class Person{

private int age;

public int getAge(){
     return age;
}

public void setAge(int age){
     this.age = age;
}
}

i think this is you want.. and this also called pojo

Why such complications?

public static GregorianCalendar convertFromDMY(String dd_mm_yy) throws ParseException 
{
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    Date date = fmt.parse(dd_mm_yy);
    GregorianCalendar cal = GregorianCalendar.getInstance();
    cal.setTime(date);
    return cal;
}

There is one very interesting application by Stéphane Sudre which does all of this for you, is scriptable / supports building from the command line, has a super nice GUI and is FREE. Sad thing is: it's called "Packages" which makes it impossible to find in google.

http://s.sudre.free.fr/Software/Packages/about.html

I wished I had known about it before I started handcrafting my own scripts.

Yes, it makes sense.

Angular modules don't try to solve the problem of script load ordering or lazy script fetching. These goals are orthogonal and both module systems can live side by side and fulfil their goals.

throw or throw ex, both are used to throw or rethrow the exception, when you just simply log the error information and don't want to send any information back to the caller you simply log the error in catch and leave. But incase you want to send some meaningful information about the exception to the caller you use throw or throw ex. Now the difference between throw and throw ex is that throw preserves the stack trace and other information but throw ex creates a new exception object and hence the original stack trace is lost. So when should we use throw and throw e, There are still a few situations in which you might want to rethrow an exception like to reset the call stack information. For example, if the method is in a library and you want to hide the details of the library from the calling code, you don’t necessarily want the call stack to include information about private methods within the library. In that case, you could catch exceptions in the library’s public methods and then rethrow them so that the call stack begins at those public methods.

The question is already answered but I wanted to point out another solution which is fast and works if length is not meant to be changed at run-time. Use macro #define before main() to define length and in main() your initialization will work:

#define length 10

int main()
{
    int boardAux[length][length] = {{0}};
}

Macros are run before the actual compilation and length will be a compile-time constant (as referred by David Rodríguez in his answer). It will actually substitute length with 10 before compilation.

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

you need to put a dot between the class like

class="column.wrapper">

There are a least these apt-get extension packages that can help:

apt-offline - offline apt package manager
apt-zip - Update a non-networked computer using apt and removable media

This is specifically for the case of wanting to download where you have network access but to install on another machine where you do not.

Otherwise, the --download-only option to apt-get is your friend:

 -d, --download-only
     Download only; package files are only retrieved, not unpacked or installed.
     Configuration Item: APT::Get::Download-Only.

try this:

i=new Array("aaaa", "bbbb");
j=new Array("cccc", "dddd");

i=i.concat(j);

Technically redirect should be used either if we need to transfer control to different domain or to achieve separation of task.

For example in the payment application we do the PaymentProcess first and then redirect to displayPaymentInfo. If the client refreshes the browser only the displayPaymentInfo will be done again and PaymentProcess will not be repeated. But if we use forward in this scenario, both PaymentProcess and displayPaymentInfo will be re-executed sequentially, which may result in incosistent data.

For other scenarios, forward is efficient to use since as it is faster than sendRedirect

Javac – compiler that converts source code to byte code. JVM- interpreter that converts byte code to machine language code.

As we know java is both compile**r & **interpreter based language. Once the java code also known as source code is compiled, it gets converted to native code known as BYTE CODE which is portable & can be easily executed on all operating systems. Byte code generated is basically represented in hexa decimal format. This format is same on every platform be it Solaris work station or Macintosh, windows or Linux. After compilation, the interpreter reads the generated byte code & translates it according to the host machine. . Byte code is interpreted by Java Virtual Machine which is available with all the operating systems we install. so to port Java programs to a new platform all that is required is to port the interpreter and some of the library routines.

Hope it helps!!!

The following answer is based my understanding & some test.

What is String[] args?

Ans- >

String[] -> As We know this is a simple String array.

args -> is the name of an array it can be anything (e.g. a, ar, argument, param, parameter) no issues with compiler & executed & I tested as well.

E.g.
1)public static void main(String[] argument)

2)public static void main(String[] parameter)

When would you use these args?

Ans->

The main function is designed very intelligently by developers. Actual thinking is very deep. Which is basically developed under consideration of C & C++ based on Command line argument but nowadays nobody uses it more.

Thing 1- User can enter any type of data from the command line can be Number or String & necessary to accept it by the compiler which datatype we should have to use? see the thing 2

Thing 2- String is the datatype which supports all of the primitive datatypes like int, long, float, double, byte, shot, char in Java. You can easily parse it in any primitive datatype.

E.g The following program is compiled & executed & I tested as well.

If input is -> 1 1

// one class needs to have a main() method
public class HelloWorld
{
  // arguments are passed using the text field below this editor
  public static void main(String[] parameter)
  {    
System.out.println(parameter[0] + parameter[1]); // Output is 11

//Comment out below code in case of String
    System.out.println(Integer.parseInt(parameter[0]) + Integer.parseInt(parameter[1])); //Output is 2
    System.out.println(Float.parseFloat(parameter[0]) + Float.parseFloat(parameter[1])); //Output is 2.0    
    System.out.println(Long.parseLong(parameter[0]) + Long.parseLong(parameter[1])); //Output is 2    
    System.out.println(Double.parseDouble(parameter[0]) + Double.parseDouble(parameter[1])); //Output is 2.0    

  }
}

Below is a very irritating example of how JavaScript can get you into trouble:

If you just try to use parseInt() to convert to number and then add another number to the result it will concatenate two strings.

However, you can solve the problem by placing the sum expression in parentheses as shown in the example below.

Result: Their age sum is: 98; Their age sum is NOT: 5048

<!DOCTYPE html>_x000D_
<html>_x000D_
<body>_x000D_
_x000D_
<p id="demo"></p>_x000D_
_x000D_
<script>_x000D_
function Person(first, last, age, eye) {_x000D_
    this.firstName = first;_x000D_
    this.lastName = last;_x000D_
    this.age = age;_x000D_
    this.eyeColor = eye;_x000D_
}_x000D_
_x000D_
var myFather = new Person("John", "Doe", "50", "blue");_x000D_
var myMother = new Person("Sally", "Rally", 48, "green");_x000D_
_x000D_
document.getElementById("demo").innerHTML = "Their age sum is: "+_x000D_
 (parseInt(myFather.age)+myMother.age)+"; Their age sum is NOT: " +_x000D_
 parseInt(myFather.age)+myMother.age; _x000D_
</script>_x000D_
_x000D_
</body>_x000D_
</html>

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

or an ORACLE version:

delete
  from table_name
 where trunc(table_name.date) > to_date('01/01/2009','mm/dd/yyyy') 

You can use this command to quit an app in iOS Simulator

xcrun simctl terminate booted com.apple.mobilesafari

You will need to know the bundle id of the app you have installed in the simulator. You can refer to this link

What about this:

double? amount = string.IsNullOrEmpty(strAmount) ? (double?)null : Convert.ToDouble(strAmount);

Of course, this doesn't take into account the convert failing.

Both r+ and w+ can read and write to a file. However, r+ doesn't delete the content of the file and doesn't create a new file if such file doesn't exist, whereas w+ deletes the content of the file and creates it if it doesn't exist.

You mean you want to add a new row and only put data in a certain column? Try the following:

var row = dataTable.NewRow();
row[myColumn].Value = "my new value";
dataTable.Add(row);

As it is a data table, though, there will always be data of some kind in every column. It just might be DBNull.Value instead of whatever data type you imagine it would be.

You could also sidestep nested cursor issues, general cursor issues, and global variable issues by avoiding the cursors entirely.

declare @rowid int
declare @rowid2 int
declare @id int
declare @type varchar(10)
declare @rows int
declare @rows2 int
declare @outer table (rowid int identity(1,1), id int, type varchar(100))
declare @inner table (rowid int  identity(1,1), clientid int, whatever int)

insert into @outer (id, type) 
Select id, type from sometable

select @rows = count(1) from @outer
while (@rows > 0)
Begin
    select top 1 @rowid = rowid, @id  = id, @type = type
    from @outer
    insert into @innner (clientid, whatever ) 
    select clientid whatever from contacts where contactid = @id
    select @rows2 = count(1) from @inner
    while (@rows2 > 0)
    Begin
        select top 1 /* stuff you want into some variables */
        /* Other statements you want to execute */
        delete from @inner where rowid = @rowid2
        select @rows2 = count(1) from @inner
    End  
    delete from @outer where rowid = @rowid
    select @rows = count(1) from @outer
End

You should do it this way, if you want to get yesterday and tomorrow at 00:00:00 time:

DateTime yesterday = DateTime.Today.AddDays(-1);
DateTime tomorrow = DateTime.Today.AddDays(1); // Output example: 6. 02. 2016 00:00:00

Just bare in mind that if you do it this way:

DateTime yesterday = DateTime.Now.AddDays(-1);
DateTime tomorrow = DateTime.Now.AddDays(1); // Output example: 6. 02. 2016 18:09:23

then you will get the current time minus one day, and not yesterday at 00:00:00 time.

def median(array):
    if len(array) < 1:
        return(None)
    if len(array) % 2 == 0:
        median = (array[len(array)//2-1: len(array)//2+1])
        return sum(median) / len(median)
    else:
        return(array[len(array)//2])

Try this:-

File file = new File("contactids.txt");
Scanner scanner = new Scanner(file);
while(scanner.hasNextLong())
{
  // Read values here like long input = scanner.nextLong();
}

My approach was as follows (in PHP):

$url = "whatever_you_need"

$html = file_get_contents('https://en.wikipedia.org/w/api.php?action=opensearch&search='.$url);
$utf8html = html_entity_decode(preg_replace("/U\+([0-9A-F]{4})/", "&#x\\1;", $html), ENT_NOQUOTES, 'UTF-8');

$utf8html might need further cleaning, but that's basically it.

FOR EXAMPLE

This is a tool to open Java class file binaries, view their internal structure, modify portions of it if required and save the class file back. It also generates readable reports similar to the javap utility. Easy to use Java Swing GUI. The user interface tries to display as much detail as possible and tries to present a structure as close as the actual Java class file structure. At the same time ease of use and class file consistency while doing modifications is also stressed. For example, when a method is deleted, the associated constant pool entry will also be deleted if it is no longer referenced. In built verifier checks changes before saving the file. This tool has been used by people learning Java class file internals. This tool has also been used to do quick modifications in class files when the source code is not available." this is a quote from the website.

Here's a list of some relatively high-profile things built in Django:

1. The Guardian's "Investigate your MP's expenses" app

2. Politifact.com (here's a Blog post talking about the (positive) experience. Site won a Pulitzer.

3. NY Times' Represent app

4. EveryBlock

5. Peter Harkins, one of the programmers over at WaPo, lists all the stuff they’ve built with Django on his blog

6. It's a little old, but someone from the LA Times gave a basic overview of why they went with Django.

7. The Onion's AV Club was recently moved from (I think Drupal) to Django.

I imagine a number of these these sites probably gets well over 100k+ hits per day. Django can certainly do 100k hits/day and more. But YMMV in getting your particular site there depending on what you're building.

There are caching options at the Django level (for example caching querysets and views in memcached can work wonders) and beyond (upstream caches like Squid). Database Server specifications will also be a factor (and usually the place to splurge), as is how well you've tuned it. Don't assume, for example, that Django's going set up indexes properly. Don't assume that the default PostgreSQL or MySQL configuration is the right one.

Furthermore, you always have the option of having multiple application servers running Django if that is the slow point, with a software or hardware load balancer in front.

Finally, are you serving static content on the same server as Django? Are you using Apache or something like nginx or lighttpd? Can you afford to use a CDN for static content? These are things to think about, but it's all very speculative. 100k hits/day isn't the only variable: how much do you want to spend? How much expertise do you have managing all these components? How much time do you have to pull it all together?

By default there will be no branches listed and pops up only after some file is placed. You don't have to worry much about it. Just run all your commands like creating folder structures, adding/deleting files, commiting files, pushing it to server or creating branches. It works seamlessly without any issue.

If you are using MAC Catalina you need to update the .zshrc file instead of .bash_profile or .profile

Take a look at the bash source code here, and specifically look in examples/loadables/mkdir.c especially lines 136-210. If you don't want to do that, here's some of the source that deals with this (taken straight from the tar.gz that I've linked):

      {
          builtin_error ("%s: %s", path, strerror (errno));
          return 1;
      }

      return 0;
  }

    p++;

  while (p = strchr (p, '/'))

      *p = '\0';

      {
          if (mkdir (npath, parent_mode))
          {
              builtin_error ("cannot create directory `%s': %s", npath, strerror (errno));
              umask (original_umask);
              free (npath);
              return 1;
          }
      }
      else if (S_ISDIR (sb.st_mode) == 0)

You can probably get away with a less general implementation.

(1) list[...]<- I had posted this over a decade ago on r-help. Since then it has been added to the gsubfn package. It does not require a special operator but does require that the left hand side be written using list[...] like this:

library(gsubfn)  # need 0.7-0 or later
list[a, b] <- functionReturningTwoValues()

If you only need the first or second component these all work too:

list[a] <- functionReturningTwoValues()
list[a, ] <- functionReturningTwoValues()
list[, b] <- functionReturningTwoValues()

(Of course, if you only needed one value then functionReturningTwoValues()[[1]] or functionReturningTwoValues()[[2]] would be sufficient.)

See the cited r-help thread for more examples.

(2) with If the intent is merely to combine the multiple values subsequently and the return values are named then a simple alternative is to use with :

myfun <- function() list(a = 1, b = 2)

list[a, b] <- myfun()
a + b

# same
with(myfun(), a + b)

(3) attach Another alternative is attach:

attach(myfun())
a + b

ADDED: with and attach

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

None of the css trick worked for me (in my case the fb-like box was pulled right with "float:right"). However, what worked without any additional tricks is an IFRAME version of the button code. I.e.:

<iframe src="//www.facebook.com/plugins/like.php?href=..." 
        scrolling="no" frameborder="0" 
        style="border:none; overflow:hidden; width:71px; height:21px;" 
        allowTransparency="true">
</iframe>

(Note custom width in style, and no need to include additional javascript.)

There is one thing that many people don't realize right away when dealing with loops and invariants. They get confused between the loop invariant, and the loop conditional ( the condition which controls termination of the loop ).

As people point out, the loop invariant must be true

1. before the loop starts
2. before each iteration of the loop
3. after the loop terminates

( although it can temporarily be false during the body of the loop ). On the other hand the loop conditional must be false after the loop terminates, otherwise the loop would never terminate.

Thus the loop invariant and the loop conditional must be different conditions.

A good example of a complex loop invariant is for binary search.

bsearch(type A[], type a) {
start = 1, end = length(A)

    while ( start <= end ) {
        mid = floor(start + end / 2)

        if ( A[mid] == a ) return mid
        if ( A[mid] > a ) end = mid - 1
        if ( A[mid] < a ) start = mid + 1

    }
    return -1

}

So the loop conditional seems pretty straight forward - when start > end the loop terminates. But why is the loop correct? What is the loop invariant which proves it's correctness?

The invariant is the logical statement:

if ( A[mid] == a ) then ( start <= mid <= end )

This statement is a logical tautology - it is always true in the context of the specific loop / algorithm we are trying to prove. And it provides useful information about the correctness of the loop after it terminates.

If we return because we found the element in the array then the statement is clearly true, since if A[mid] == a then a is in the array and mid must be between start and end. And if the loop terminates because start > end then there can be no number such that start <= mid and mid <= end and therefore we know that the statement A[mid] == a must be false. However, as a result the overall logical statement is still true in the null sense. ( In logic the statement if ( false ) then ( something ) is always true. )

Now what about what I said about the loop conditional necessarily being false when the loop terminates? It looks like when the element is found in the array then the loop conditional is true when the loop terminates!? It's actually not, because the implied loop conditional is really while ( A[mid] != a && start <= end ) but we shorten the actual test since the first part is implied. This conditional is clearly false after the loop regardless of how the loop terminates.

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

e.g.

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

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

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

public static void main(String[] args) {

try {
        String keystorePass = "20174";
        String keyPass = "rav@789";
        String alias = "TyaGi!";
        InputStream keystoreStream = new FileInputStream("D:/keyFile.jks");
        KeyStore keystore = KeyStore.getInstance("JCEKS");
        keystore.load(keystoreStream, keystorePass.toCharArray());
        Key key = keystore.getKey(alias, keyPass.toCharArray());

        byte[] bt = key.getEncoded();
        String s = new String(bt);
        System.out.println("------>"+s);      
        String str12 = Base64.encodeBase64String(bt);

        System.out.println("Fetched Key From JKS : " + str12);

    } catch (KeyStoreException | IOException | NoSuchAlgorithmException | CertificateException | UnrecoverableKeyException ex) {
        System.out.println(ex);

    }
}

If you're not interested in getting a reliable representation of the bad character(s) you might use something like this (working with python >= 2.6, including 3.x):

from __future__ import print_function
import sys

def safeprint(s):

The bad character(s) in the string will be converted in a representation which is printable by the Windows console.

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

If you don't know the exact class of your number (Integer, Long, Double, whatever), you can cast to Number and get your long value from it:

Object num = new Integer(6);
Long longValue = ((Number) num).longValue();

From Java documents -

You should use enum types any time you need to represent a fixed set of constants. That includes natural enum types such as the planets in our solar system and data sets where you know all possible values at compile time—for example, the choices on a menu, command line flags, and so on.

A common example is to replace a class with a set of private static final int constants (within reasonable number of constants) with an enum type. Basically if you think you know all possible values of "something" at compile time you can represent that as an enum type. Enums provide readability and flexibility over a class with constants.

Few other advantages that I can think of enum types. They is always one instance of a particular enum class (hence the concept of using enums as singleton arrives). Another advantage is you can use enums as a type in switch-case statement. Also you can use toString() on the enum to print them as readable strings.

Check out the built-in function encodeURIComponent(str) and encodeURI(str).
In your case, this should work:

var myOtherUrl = 
       "http://example.com/index.html?url=" + encodeURIComponent(myUrl);

According to Oracle's Java Documentation:

private static final Pattern NUMBER_PATTERN = Pattern.compile(
        "[\\x00-\\x20]*[+-]?(NaN|Infinity|((((\\p{Digit}+)(\\.)?((\\p{Digit}+)?)" +
        "([eE][+-]?(\\p{Digit}+))?)|(\\.((\\p{Digit}+))([eE][+-]?(\\p{Digit}+))?)|" +
        "(((0[xX](\\p{XDigit}+)(\\.)?)|(0[xX](\\p{XDigit}+)?(\\.)(\\p{XDigit}+)))" +
        "[pP][+-]?(\\p{Digit}+)))[fFdD]?))[\\x00-\\x20]*");
boolean isNumber(String s){
return NUMBER_PATTERN.matcher(s).matches()
}

The query to use with Oracle is:

String sqlStr="select COLUMN_NAME from ALL_TAB_COLUMNS where TABLE_NAME='"+_db+".users' and COLUMN_NAME not in ('password','version','id')"

Never heard of HQL for such queries. I assume it doesn't make sense for ORM implementations to deal with it. ORM is an Object Relational Mapping, and what you're looking for is metadata mapping... You wouldn't use HQL, rather use API methods for this purpose, or direct SQL. For instance, you can use JDBC DatabaseMetaData.

I think tablespace has nothing to do with schema. AFAIK tablespaces are mainly used for logical internal technical purposes which should bother DBAs. For more information regarding tablespaces, see Oracle doc.

+= is an assignment. When you use it you're really saying ‘some_list2= some_list2+['something']’. Assignments involve rebinding, so:

l= []

def a1(x):
    l.append(x) # works

def a2(x):
    l= l+[x] # assign to l, makes l local
             # so attempt to read l for addition gives UnboundLocalError

def a3(x):
    l+= [x]  # fails for the same reason

The += operator should also normally create a new list object like list+list normally does:

>>> l1= []
>>> l2= l1

>>> l1.append('x')
>>> l1 is l2
True

>>> l1= l1+['x']
>>> l1 is l2
False

However in reality:

>>> l2= l1
>>> l1+= ['x']
>>> l1 is l2
True

This is because Python lists implement __iadd__() to make a += augmented assignment short-circuit and call list.extend() instead. (It's a bit of a strange wart this: it usually does what you meant, but for confusing reasons.)

In general, if you're appending/extended an existing list, and you want to keep the reference to the same list (instead of making a new one), it's best to be explicit and stick with the append()/extend() methods.

try:

$("td[id^=" + value + "]")

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

Code below does not print boolean, but allows for dataframe subsetting by index... I understand this is likely not the most efficient way to solve the problem, but I (1) like the way this reads and (2) you can easily subset where df1 index exists in df2:

df3 = df1[df1.index.isin(df2.index)]

or where df1 index does not exist in df2...

df3 = df1[~df1.index.isin(df2.index)]

The three dots (...) are called the spread operator, and this is conceptually similar to the ES6 array spread operator, JSX taking advantage of these supported and developing standards in order to provide a cleaner syntax in JSX

Spread properties in object initializers copies own enumerable properties from a provided object onto the newly created object.

let n = { x, y, ...z };
n; // { x: 1, y: 2, a: 3, b: 4 }

Reference:

2) https://facebook.github.io/react/docs/jsx-spread.html

You have to specify any one of the above phase to resolve the above error. In most of the situations, this would have occurred due to running the build from the eclipse environment.

instead of mvn clean package or mvn package you can try only package its work fine for me

Old question, but I should note that the general task of parsing XLS files from javascript is tedious and difficult but not impossible.

I have basic parsers implemented in pure JS:

• http://oss.sheetjs.com/js-xls/ (XLS files, what you wanted)
• http://oss.sheetjs.com/js-xlsx/ (XLSX/XLSM/XLSB files)

Both pages are HTML5 File API-driven XLS/XLSX parsers (you can drag-drop your file and it will print out the data in the cells in a comma-separated list). You can also generate JSON objects (assuming the first row is a header row).

The test suite http://oss.sheetjs.com/ shows a version that uses XHR to get and parse files.

I have same problem, and solve by this way:

1. Open CMD
2. Go to file netbeans.exe
3. Press Shift Key + Right Click and copy as path Copy as path
4. Paste on CMD look like C:\Users\unnamed>"C:\Users\unnamed\Downloads\Programs\netbeans-8.2-windows.exe"
5. Write --javahome do same point 2 on JDK folder

6. Write on cmd look like C:\Users\unnamed>"C:\Users\unnamed\Downloads\Programs\netbeans-8.2-windows.exe" --javahome "C:\Program Files\Java\jdk-9.0.4"

7. Enter. Enjoy it.

So without Extension functions if you are looking for simple and easy.. This is what I did

<%= Html.DropDownListFor(x => x.CurrentAddress.State, new SelectList(Enum.GetValues(typeof(XXXXX.Sites.YYYY.Models.State))))%>

where XXXXX.Sites.YYYY.Models.State is an enum

Probably better to do helper function, but when time is short this will get the job done.

As dplyr 1.0.0 deprecated the scoped variants which @Feng Mai nicely showed, here is an update with the new syntax. This might be useful because in this case, across() doesn't work, and it took me some time to figure out the solution as follows.

The goal was to extract all rows that contain at least one 0 in a column.

df %>% 
  rowwise() %>% 
  filter(any(c_across(everything(.)) == 0))

with the data

df <- data.frame(a = 1:4, b= 1:0, c=0:3)
df <- rbind(df, c(0,0,0))
df <- rbind(df, c(9,9,9))

# A tibble: 4 x 3
# Rowwise: 
      a     b     c
  <dbl> <dbl> <dbl>
1     1     1     0
2     2     0     1
3     4     0     3
4     0     0     0

So it correctly doesn't return the last row containing all 9s.

An alternative for the bind() method.

Use the click() method, do something like this:

commentbtn.click({id: 10, name: "João"}, onClickCommentBtn);

function onClickCommentBtn(event)
{
  alert("Id=" + event.data.id + ", Name = " + event.data.name);
}

Or, if you prefer:

commentbtn.click({id: 10, name: "João"},  function (event) {
  alert("Id=" + event.data.id + ", Nome = " + event.data.name);
});

It will show an alert box with the following infos:

Id = 10, Name = João

If the destination table does exist but you don't want to specify column names:

DECLARE @COLUMN_LIST NVARCHAR(MAX);
DECLARE @SQL_INSERT NVARCHAR(MAX);

SET @COLUMN_LIST = (SELECT DISTINCT
    SUBSTRING(
        (
            SELECT ', table1.' + SYSCOL1.name  AS [text()]
            FROM sys.columns SYSCOL1
            WHERE SYSCOL1.object_id = SYSCOL2.object_id and SYSCOL1.is_identity <> 1
            ORDER BY SYSCOL1.object_id
            FOR XML PATH ('')
        ), 2, 1000)
FROM
    sys.columns SYSCOL2
WHERE
    SYSCOL2.object_id = object_id('dbo.TableOne') )

SET @SQL_INSERT =  'INSERT INTO dbo.TableTwo SELECT ' + @COLUMN_LIST + ' FROM dbo.TableOne table1 WHERE col3 LIKE ' + @search_key
EXEC sp_executesql @SQL_INSERT

Use this method:

Process.Start(String, String)

First argument is an application (explorer.exe), second method argument are arguments of the application you run.

For example:

in CMD:

explorer.exe -p

in C#:

Process.Start("explorer.exe", "-p")

Since scipy's imread is deprecated, use imageio.imread.

1. Install - pip install imageio
2. Use height, width, channels = imageio.imread(filepath).shape

For String, int, boolean, the best choice would be sharedPreferences.

If you want to store ArrayList or any complex data. The best choice would be Paper library.

Add dependency

implementation 'io.paperdb:paperdb:2.6'

Initialize Paper

Should be initialized once in Application.onCreate():

Paper.init(context);

Save

List<Person> contacts = ...
Paper.book().write("contacts", contacts);

Loading Data

Use default values if object doesn't exist in the storage.

List<Person> contacts = Paper.book().read("contacts", new ArrayList<>());

Here you go.

Below a fully functional method to get hard disk serial number:

public string GetHardDiskSerialNo()
    {
        ManagementClass mangnmt = new ManagementClass("Win32_LogicalDisk");
        ManagementObjectCollection mcol = mangnmt.GetInstances();
        string result = "";
        foreach (ManagementObject strt in mcol)
        {
            result += Convert.ToString(strt["VolumeSerialNumber"]);
        }
        return result;
    }

If you are using Git Extensions you should be able to find your local changes in the Working directory as shown below:

If you don't see any changes, it's probably because you are on a wrong sub-module. So check all the items with a submarine icon as shown below:

When you found some uncommitted change:

Select the line with Working directory, navigate to Diff tab, Right click on rows with a pencil (or + or -) icon, choose Reset to first commit or commit or stash or whatever you want to do with it.

Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.

If you're a minimalist like me. Say you only want to render a record with a list containing entries.

<div>
  {data.map((record) => (
    record.list.length > 0
      ? (<YourRenderComponent record={record} key={record.id} />)
      : null
  ))}
</div>

This depends on what shell you are using. If you are using bash, then the ulimit command controls several settings relating to program execution, such as whether you should dump core. If you type

ulimit -c unlimited

then that will tell bash that its programs can dump cores of any size. You can specify a size such as 52M instead of unlimited if you want, but in practice this shouldn't be necessary since the size of core files will probably never be an issue for you.

In tcsh, you'd type

limit coredumpsize unlimited

For me, this issue was caused in my build system (Travis CI) by doing something kind of dumb in my .travis.yml file. In effect, I was calling npm install before nvm use 0.12, and this was causing node-sass to be built for 0.10 instead of 0.12. My solution was simply moving nvm use out of the .travis.yml file’s before_script section to before the npm install command, which was in the before_install section.

In your case, it is likely that whatever process you are starting with gulp is using a different version of node (than what you would expect).

There's more than one way to do this obviously.

    # This will find files recursively (you can limit it by using some 'find' parameters. 
    # see the man pages
    # Final backslash required for exec example to work
    find . -name '*.gz' -exec gunzip '{}' \;

    # This will do it only in the current directory
    for a in *.gz; do gunzip $a; done

I'm sure there's other ways as well, but this is probably the simplest.

And to remove it, just do a rm -rf *.gz in the applicable directory

Is it very expensive to do this by json convert? But at least you have a 2 line solution and its generic. It does not matter eather if your datatable contains more or less fields than the object class:

Dim sSql = $"SELECT '{jobID}' AS ConfigNo, 'MainSettings' AS ParamName, VarNm AS ParamFieldName, 1 AS ParamSetId, Val1 AS ParamValue FROM StrSVar WHERE NmSp = '{sAppName} Params {jobID}'"
            Dim dtParameters As DataTable = DBLib.GetDatabaseData(sSql)

            Dim paramListObject As New List(Of ParameterListModel)()

            If (Not dtParameters Is Nothing And dtParameters.Rows.Count > 0) Then
                Dim json = Newtonsoft.Json.JsonConvert.SerializeObject(dtParameters).ToString()

                paramListObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of List(Of ParameterListModel))(json)
            End If

MySQL added this utf8mb4 code after 5.5.3, Mb4 is the most bytes 4 meaning, specifically designed to be compatible with four-byte Unicode. Fortunately, UTF8MB4 is a superset of UTF8, except that there is no need to convert the encoding to UTF8MB4. Of course, in order to save space, the general use of UTF8 is enough.

The original UTF-8 format uses one to six bytes and can encode 31 characters maximum. The latest UTF-8 specification uses only one to four bytes and can encode up to 21 bits, just to represent all 17 Unicode planes. UTF8 is a character set in Mysql that supports only a maximum of three bytes of UTF-8 characters, which is the basic multi-text plane in Unicode.

To save 4-byte-long UTF-8 characters in Mysql, you need to use the UTF8MB4 character set, but only 5.5. After 3 versions are supported (View version: Select version ();). I think that in order to get better compatibility, you should always use UTF8MB4 instead of UTF8. For char type data, UTF8MB4 consumes more space and, according to Mysql's official recommendation, uses VARCHAR instead of char.

In MariaDB utf8mb4 as the default CHARSET when it not set explicitly in the server config, hence COLLATE utf8mb4_unicode_ci is used.

Refer MariaDB CHARSET & COLLATE Click

CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

using jquery without prototype, update the js code to

$( ".stars" ).each(function() { 
    // Get the value
    var val = $(this).data("rating");
    // Make sure that the value is in 0 - 5 range, multiply to get width
    var size = Math.max(0, (Math.min(5, val))) * 16;
    // Create stars holder
    var $span = $('<span />').width(size);
    // Replace the numerical value with stars
    $(this).html($span);
});

I also added a data attribute by the name of data-rating in the span.

<span class="stars" data-rating="4" ></span>

Have a look at CONVERT. The 3rd parameter is the date time style you want to convert to.

e.g.

SELECT CONVERT(VARCHAR(10), GETDATE(), 103) -- dd/MM/yyyy format

I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:

 [ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    ForDataset GetCCDBdata();

    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    string GetCCDBdataasXMLstring();


    //[OperationContract]
    //string GetData(int value);

    //[OperationContract]
    //CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

  [DataContract]
public class ServiceData
{
    [DataMember]
    public bool Result { get; set; }
    [DataMember]
    public string ErrorMessage { get; set; }
    [DataMember]
    public string ErrorDetails { get; set; }
}

in your service1.svc.cs you can use this in the catch block:

 catch (Exception ex)
        {
            myServiceData.Result = false;
            myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
            myServiceData.ErrorDetails = ex.ToString();
            throw new FaultException<ServiceData>(myServiceData, ex.ToString());
        }

And use this in the Client application like below code:

  ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();

            string str = obj.GetCCDBdataasXMLstring();

        }

        catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
      {
          Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
          Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
          Console.ReadLine();
      }

Just try this, it will help for sure to get the exact issue.

If you need to set the credentials on the fly, have a look at this source:

http://spc3.codeplex.com/SourceControl/changeset/view/57957#1015709

private ICredentials BuildCredentials(string siteurl, string username, string password, string authtype) {
    NetworkCredential cred;
    if (username.Contains(@"\")) {
        string domain = username.Substring(0, username.IndexOf(@"\"));
        username = username.Substring(username.IndexOf(@"\") + 1);
        cred = new System.Net.NetworkCredential(username, password, domain);
    } else {
        cred = new System.Net.NetworkCredential(username, password);
    }
    CredentialCache cache = new CredentialCache();
    if (authtype.Contains(":")) {
        authtype = authtype.Substring(authtype.IndexOf(":") + 1); //remove the TMG: prefix
    }
    cache.Add(new Uri(siteurl), authtype, cred);
    return cache;
}

Here's my solution to this type of problem:

Create a new class in CSS and position off screen. Then put your alt text in HTML right before the property that calls your background image. Can be any tag, H1, H2, p, etc.

CSS

<style type="text/css">
  .offleft {
    margin-left: -9000px;
    position: absolute;
  }
</style>

HTML

<h1 class="offleft">put your alt text here</h1>
<div class or id that calls your bg image>  </div>

You need to separate the arguments from the file path:

powershell.exe -noexit "& 'D:\Work\SQLExecutor.ps1 ' -gettedServerName 'MY-PC'"

Another option that may ease the syntax using the File parameter and positional parameters:

powershell.exe -noexit -file "D:\Work\SQLExecutor.ps1" "MY-PC"

for me, i did this and it worked. just go to C:\Users\$your username$\AppData(which is hidden most likely)\Local\ then at this location try to find this Folder : "Android" if you don't have it already make one with the exact name and try to open the android studio again.

Try javascript into your Ajax

window.onbeforeunload = function(){
  return 'Are you sure you want to leave?';
};

Reference link

Example 2:

document.getElementsByClassName('eStore_buy_now_button')[0].onclick = function(){
    window.btn_clicked = true;
};
window.onbeforeunload = function(){
    if(!window.btn_clicked){
        return 'You must click "Buy Now" to make payment and finish your order. If you leave now your order will be canceled.';
    }
};

Here it will alert the user every time he leaves the page, until he clicks on the button.

I know this is an old question but I came here first and then discovered the atexit module. I do not know about its cross-platform track record or a full list of caveats yet, but so far it is exactly what I was looking for in trying to handle post-KeyboardInterrupt cleanup on Linux. Just wanted to throw in another way of approaching the problem.

I want to do post-exit clean-up in the context of Fabric operations, so wrapping everything in try/except wasn't an option for me either. I feel like atexit may be a good fit in such a situation, where your code is not at the top level of control flow.

atexit is very capable and readable out of the box, for example:

import atexit

def goodbye():
    print "You are now leaving the Python sector."

atexit.register(goodbye)

You can also use it as a decorator (as of 2.6; this example is from the docs):

import atexit

@atexit.register
def goodbye():
    print "You are now leaving the Python sector."

If you wanted to make it specific to KeyboardInterrupt only, another person's answer to this question is probably better.

But note that the atexit module is only ~70 lines of code and it would not be hard to create a similar version that treats exceptions differently, for example passing the exceptions as arguments to the callback functions. (The limitation of atexit that would warrant a modified version: currently I can't conceive of a way for the exit-callback-functions to know about the exceptions; the atexit handler catches the exception, calls your callback(s), then re-raises that exception. But you could do this differently.)

For more info see:

• Official documentation on atexit
• The Python Module of the Week post, a good intro

I'm using Excel 2003 -

The problem with using conditional formatting here is that you can't reference another worksheet or workbook in your conditions. What you can to do is set some column on sheet 1 equal to the appropriate column on sheet 2 (in your example =Sheet2!B6). I used Column F in my example below. Then you can use conditional formatting. Select the cell at Sheet 1, row , column 1 and then go to the conditional formatting menu. Choose "Formula Is" from the drop down and set the condition to "=$F$6=4". Click on the format button and then choose the Patterns tab. Choose the color you want and you're done.

You can use the format painter tool to apply conditional formatting to other cells, but be aware that by default Excel uses absolute references in the conditions. If you want them to be relative you'll need to remove the dollar signs from the condition.

You can have up to 3 conditions applied to a cell (use the add >> button at the bottom of the Conditional formatting dialog) so if the last row is fixed (for example, you know that it will always be row 10) you can use it as a condition to set the background color to none. Assuming that the last value you care about is in row 10 then (still assuming that you've set column F on sheet1 to the corresponding cells on sheet 2) then set the 1st condition to Formula Is =$F$10="" and the pattern to None. Make it the first condition and it will override any following conflicting statements.

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

I came here trying to get my Azure DevOps Command Line task working. The thing that worked for me was using the pipe (|) character. Using > did not work.

Example:

steps:
- task: CmdLine@2
  inputs:
    script: |
      echo "Selecting Mono version..."
      /bin/bash -c "sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh 5_18_1"
      echo "Selecting Xcode version..."
      /bin/bash -c "echo '##vso[task.setvariable variable=MD_APPLE_SDK_ROOT;]'/Applications/Xcode_10.2.1.app;sudo xcode-select --switch /Applications/Xcode_10.2.1.app/Contents/Developer"

To translate your *nix style command script to windows/command batch style it would go like this:

SET PROJ_HOME=%USERPROFILE%/proj/111
SET PROJECT_BASEDIR=%PROJ_HOME%/exercises/ex1
mkdir "%PROJ_HOME%"

mkdir on windows doens't have a -p parameter : from the MKDIR /? help:

MKDIR creates any intermediate directories in the path, if needed.

which basically is what mkdir -p (or --parents for purists) on *nix does, as taken from the man guide

For http/https proxy with or without authentication:

Run one of the following commands in cmd.exe

set http_proxy=http://your_proxy:your_port
set http_proxy=http://username:password@your_proxy:your_port
set https_proxy=https://your_proxy:your_port
set https_proxy=https://username:password@your_proxy:your_port

Basically you need to do two loops here. The one you are doing already is iterating each element in the 0th array element.

You have programs: [ {...}, {...} ] so programs[0] is { "name":"zonealarm", "price":"500" } So your loop is just going over that.

You could do an outer loop over the array

$.each(data.programs, function(index) {

    // then loop over the object elements
    $.each(data.programs[index], function(key, value) {
        console.log(key + ": " + value);
    }

}

Use this

select cast((1*1.00)/3 AS DECIMAL(16,2)) as Result

Here in this sql first convert to float or multiply by 1.00 .Which output will be a float number.Here i consider 2 decimal places. You can choose what you need.

Remove space between classes in css selector:

driver.find_element_by_css_selector('.button .c_button .s_button').click()
#                                           ^         ^

=>

driver.find_element_by_css_selector('.button.c_button.s_button').click()

SKINDER, your code does not use column name. Correct script is:

declare @table_name nvarchar(256)  
declare @col_name nvarchar(256)  
declare @Command  nvarchar(1000)  

set @table_name = N'users'
set @col_name = N'login'

select @Command = 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name
    from sys.tables t 
    join sys.indexes d on d.object_id = t.object_id  and d.type=2 and d.is_unique=1
    join sys.index_columns ic on d.index_id=ic.index_id and ic.object_id=t.object_id
    join sys.columns c on ic.column_id = c.column_id  and c.object_id=t.object_id
    where t.name = @table_name and c.name=@col_name

print @Command

--execute (@Command)

As explained by Ron, there are two variables, local and global. The local variable is always used, and is the same as global upon connection.

SET FOREIGN_KEY_CHECKS=0;
SET GLOBAL FOREIGN_KEY_CHECKS=0;

SHOW Variables WHERE Variable_name='foreign_key_checks'; # always shows local variable

When setting the GLOBAL variable, the local one isn't changed for any existing connections. You need to reconnect or set the local variable too.

Perhaps unintuitive, MYSQL does not enforce foreign keys when FOREIGN_KEY_CHECKS are re-enabled. This makes it possible to create an inconsistent database even though foreign keys and checks are on.

If you want your foreign keys to be completely consistent, you need to add the keys while checking is on.

I include #include <conio.h> and then, add getch(); just before the return 0; line. That's what I learnt at school anyway. The methods mentioned above here are quite different I see.

In Oracle, you could use rownum to limit the number of rows returned. I am guessing similar construct exists in other SQLs as well. So, for the example you gave, you could limit the number of rows returned to 500001 and apply a count(*) then:

SELECT (case when cnt > 500000 then 500000 else cnt end) myCnt
FROM (SELECT count(*) cnt FROM table WHERE rownum<=500001)

Can I use a field of the type ... and retrieve it after the GET / POST method ...

Yes (haven't you tried?)

Are there any other ways of using hidden fields in PHP?

You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.

Btw. input fiels have no end tag. So write either just <input ...> or as self-closing tag <input .../>.

>>> mask = df['ids'].str.contains('ball')    
>>> mask
0     True
1     True
2    False
3     True
Name: ids, dtype: bool

>>> df[mask]
     ids  vals
0  aball     1
1  bball     2
3  fball     4

Just hide them before showing them:

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("div.desc").hide();
        $("#"+test).show();
    }); 
});

Suppose your application has package name as com.company.myproject. Then you can set the logging level for classes inside your project as given below in application.properties files

logging.level.com.company.myproject = DEBUG

logging.level.org.springframework.web = DEBUG and logging.level.org.hibernate = DEBUG will set logging level for classes of Spring framework web and Hibernate only.

For setting the logging file location use

logging.file = /home/ubuntu/myproject.log

I also had this issue and ended up using Andy's code to create a function to clean things up when multiple commands need to be run.

It'll return stderr, stdout, and exit codes as objects. One thing to note: the function won't accept .\ in the path; full paths must be used.

Function Execute-Command ($commandTitle, $commandPath, $commandArguments)
{
    $pinfo = New-Object System.Diagnostics.ProcessStartInfo
    $pinfo.FileName = $commandPath
    $pinfo.RedirectStandardError = $true
    $pinfo.RedirectStandardOutput = $true
    $pinfo.UseShellExecute = $false
    $pinfo.Arguments = $commandArguments
    $p = New-Object System.Diagnostics.Process
    $p.StartInfo = $pinfo
    $p.Start() | Out-Null
    $p.WaitForExit()
    [pscustomobject]@{
        commandTitle = $commandTitle
        stdout = $p.StandardOutput.ReadToEnd()
        stderr = $p.StandardError.ReadToEnd()
        ExitCode = $p.ExitCode
    }
}

Here's how to use it:

$DisableACMonitorTimeOut = Execute-Command -commandTitle "Disable Monitor Timeout" -commandPath "C:\Windows\System32\powercfg.exe" -commandArguments " -x monitor-timeout-ac 0"

Another easier way to do it is to upload your file to google sheets, then add a pivot, for the columns and rows select the same as you would with Excel, however, for values select Calculated Field and then in the formula type in =

i have a simple solution without lot of changes. the initial statement is

I want to break the if statement above and stop executing echo "yes"; or such codes which are no longer necessary to be executed, there may be or may not be an additional condition, is there way to do this?

so, it seem simple. try code like this.

$a="test";
if("test"==$a)
{
  if (1==0){
      echo "yes"; // this line while never be executed. 
      // and can be reexecuted simply by changing if (1==0) to if (1==1) 
  }
}
echo "finish";

if you want to try without this code, it's simple. and you can back when you want. another solution is comment blocks. or simply thinking and try in another separated code and copy paste only the result in your final code. and if a code is no longer nescessary, in your case, the result can be

$a="test";
echo "finish";

with this code, the original statement is completely respected.. :) and more readable!

In Android Studio, while running an emulator:

1- Hit settings button at the bottom of the emulator sidebar

2- Go to Cellular

3- Set Network Type

sc delete Apache2.4

Remove service in windows

Some of this seems "incomplete"

Groups of people are NOT going to know if they should use quotes etc..

Add 1 specific file showing the location paths as well

git add JobManager/Controllers/APIs/ProfileApiController.cs

Commit (remember, commit is local only, it is not affecting any other system)

git commit -m "your message"  

Push to remote repo

git push  (this is after the commit and this attempts to Merge INTO the remote location you have instructed it to merge into)

Other answer(s) show the stash etc. which you sometimes will want to do

Order of installation matters a lot when configuring IIS 8 on Windows 8 or Windows Server 2012.

I faced lot of issues configuring IIS 8 but finally these links helped me

• Installing IIS 8
• Configuring WCF

when we pass vector by value in a function as an argument,it simply creates the copy of vector and no any effect happens on the vector which is defined in main function when we call that particular function. while when we pass vector by reference whatever is written in that particular function, every action will going to perform on the vector which is defined in main or other function when we call that particular function.

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

Stop using the TEXT data type in SQL Server!

It's been deprecated since the 2005 version. Use VARCHAR(MAX) instead, if you need more than 8000 characters.

The TEXT data type doesn't support the normal string functions, while VARCHAR(MAX) does - your statement would work just fine, if you'd be using just VARCHAR types.

Below is the code that works with both the email or messaging app. If you share through email then the subject and body both are added.

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
                sharingIntent.setType("text/plain");

                String shareString = Html.fromHtml("Medicine Name:" + medicine_name +
                        "<p>Store Name:" + “store_name “+ "</p>" +
                        "<p>Store Address:" + “store_address” + "</p>")  .toString();
                                      sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Medicine Enquiry");
                sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareString);

                if (sharingIntent.resolveActivity(context.getPackageManager()) != null)
                    context.startActivity(Intent.createChooser(sharingIntent, "Share using"));
                else {
                    Toast.makeText(context, "No app found on your phone which can perform this action", Toast.LENGTH_SHORT).show();
                }

(If you are using NetBeans IDE) Just create a folder in your project but out side of src folder. Named the folder Images. And then put the image into the Images folder and write code below.

// Import ImageIcon     
ImageIcon iconLogo = new ImageIcon("Images/YourCompanyLogo.png");
// In init() method write this code
jLabelYourCompanyLogo.setIcon(iconLogo);

Now run your program.

You have an error in you script tag construction, this:

<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

Should look like this:

<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.

UPDATE

But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

div {_x000D_
    width: 200px;_x000D_
    height: 50px;_x000D_
    line-height: 50px;_x000D_
    text-align: center;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
}_x000D_
_x000D_

}

<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>

The answer of RedBlueThing worked quite well for me. Here is some sample code of how I did it.

Header

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface yourController : UIViewController <CLLocationManagerDelegate> {
    CLLocationManager *locationManager;
}

@end

MainFile

In the init method

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];

Callback function

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
    NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
}

iOS 6

In iOS 6 the delegate function was deprecated. The new delegate is

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

Therefore to get the new position use

[locations lastObject]

iOS 8

In iOS 8 the permission should be explicitly asked before starting to update location

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    [self.locationManager requestWhenInUseAuthorization];

[locationManager startUpdatingLocation];

You also have to add a string for the NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription keys to the app's Info.plist. Otherwise calls to startUpdatingLocation will be ignored and your delegate will not receive any callback.

And at the end when you are done reading location call stopUpdating location at suitable place.

[locationManager stopUpdatingLocation];

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.

This will search and replace all non ASCII letters:

String resultString = subjectString.replaceAll("[^\\x00-\\x7F]", "");

Auth::routes() is just a helper class that helps you generate all the routes required for user authentication. You can browse the code here https://github.com/laravel/framework/blob/5.3/src/Illuminate/Routing/Router.php instead.

Here are the routes

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

+1 for print_r(). Use it to dump out the contents of an object or variable. To make it more readable, do it with a pre tag so you don't need to view source.

echo '<pre>';
print_r($arrayOrObject);

Also var_dump($thing) - this is very useful to see the type of subthings

.button{
    background-image:url('/image/btn.png');
    background-repeat:no-repeat;
}

Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...

PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));

So it will return false when the method is called in same test case and then it will return false again and lastly true.

You can try this:

var a = Array<Int>(5){0}

Using vh on mobile devices is not going to work with 100vh, due to their design choices using the entire height of the device not including any address bars etc.

If you are looking for a layout including div heights proportionate to the true view height I use the following pure css solution:

:root {
  --devHeight: 86vh; //*This value changes
}

.div{
    height: calc(var(--devHeight)*0.10); //change multiplier to suit required height
}

You have two options for setting the viewport height, manually set the --devHeight to a height that works (but you will need to enter this value for each type of device you are coding for)

or

Use javascript to get the window height and then update --devheight on loading and refreshing the viewport (however this does require using javascript and is not a pure css solution)

Once you obtain your correct view height you can create multiple divs at an exact percentage of total viewport height by simply changing the multiplier in each div you assign the height to.

0.10 = 10% of view height 0.57 = 57% of view height

Hope this might help someone ;)

Recent bash versions allow fall-through by using ;& in stead of ;;: they also allow resuming the case checks by using ;;& there.

for n in 4 14 24 34
do
  echo -n "$n = "
  case "$n" in
   3? )
     echo -n thirty-
     ;;&   #resume (to find ?4 later )
   "24" )
     echo -n twenty-
     ;&   #fallthru
   "4" | [13]4)
     echo -n four 
     ;;&  # resume ( to find teen where needed )
   "14" )
     echo -n teen
  esac
  echo 
done

sample output

4 = four
14 = fourteen
24 = twenty-four
34 = thirty-four

The lock statement is translated by C# 3.0 to the following:

var temp = obj;

Monitor.Enter(temp);

try
{
    // body
}
finally
{
    Monitor.Exit(temp);
}

In C# 4.0 this has changed and it is now generated as follows:

bool lockWasTaken = false;
var temp = obj;
try
{
    Monitor.Enter(temp, ref lockWasTaken);
    // body
}
finally
{
    if (lockWasTaken)
    {
        Monitor.Exit(temp); 
    }
}

You can find more info about what Monitor.Enter does here. To quote MSDN:

Use Enter to acquire the Monitor on the object passed as the parameter. If another thread has executed an Enter on the object but has not yet executed the corresponding Exit, the current thread will block until the other thread releases the object. It is legal for the same thread to invoke Enter more than once without it blocking; however, an equal number of Exit calls must be invoked before other threads waiting on the object will unblock.

The Monitor.Enter method will wait infinitely; it will not time out.

In the forms you listed here, there's not much difference between the two. CompareTo ends up calling a CompareInfo method that does a comparison using the current culture; Equals is called by the == operator.

If you consider overloads, then things get different. Compare and == can only use the current culture to compare a string. Equals and String.Compare can take a StringComparison enumeration argument that let you specify culture-insensitive or case-insensitive comparisons. Only String.Compare allows you to specify a CultureInfo and perform comparisons using a culture other than the default culture.

Because of its versatility, I find I use String.Compare more than any other comparison method; it lets me specify exactly what I want.

Seems the java procedure/function could work. But why don't you compile your function under a user like the application schema or a admin account that has this grant and just grant your developer account execute on it. That way the definer rights are used.

In Chrome 8.0.552 on a Mac, you can find this under menu View/Developer/JavaScript Console ... or you can use Alt+CMD+J.

Are you asking how to bring up a command windows? If so, you can use the Process object ...

Process.Start("cmd");

SpringBoot developers recommend to locate your main application class in a root package above other classes. Using a root package also allows the @ComponentScan annotation to be used without needing to specify a basePackage attribute. Detailed info But be sure that the custom root package exists.

You need to move your angular app code below the inclusion of the angular libraries. At the time your angular code runs, angular does not exist yet. This is an error (see your dev tools console).

In this line:

var app = angular.module(`

you are attempting to access a variable called angular. Consider what causes that variable to exist. That is found in the angular.js script which must then be included first.

  <h1>{{2+3}}</h1>

  <!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

      <script>
        var app = angular.module('myApp',[]);

        app.directive('myDirective',function(){

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>

For completeness, it is true that your directive is similar to the already existing directive ng-click, but I believe the point of this exercise is just to practice writing simple directives, so that makes sense.

This is essentially the same thing. Use whatever you find more convenient.

I know this is an older post but Bootstrap is still alive and kicking!

Slightly different to @Eduardo's post, I had to modify:

#myCarousel.carousel.slide {
    width: 100%; 
    max-width: 400px; !important
}

When I only modified .carousel-inner {}, the actual image was fixed size but the left/right controls were displaying incorrectly off to the side of the div.

What's wrong with your code? I find it to be quite elegant and simple. The only problem is that if the file doesn't end in a newline, the last line returned won't have a '\n' as the last character, and therefore doing line = line[:-1] would incorrectly strip off the last character of the line.

The most elegant way to solve this problem would be to define a generator which took the lines of the file and removed the last character from each line only if that character is a newline:

def strip_trailing_newlines(file):
    for line in file:
        if line[-1] == '\n':
            yield line[:-1]
        else:
            yield line

f = open("myFile.txt", "r")
for line in strip_trailing_newlines(f):
    # do something with line

If you need to create the regexp from a variable, this is a much better way to do it: https://stackoverflow.com/a/10728069/309514

You can then do something like:

var string = "SomeStringToFind";
var regex = new RegExp(["^", string, "$"].join(""), "i");
// Creates a regex of: /^SomeStringToFind$/i
db.stuff.find( { foo: regex } );

This has the benefit be being more programmatic or you can get a performance boost by compiling it ahead of time if you're reusing it a lot.

You can add a random (or datetime string) as query string to the url that points to your script. Like so:

<script type="text/javascript" src="test.js?q=123"></script> 

Every time you refresh the page you need to make sure the value of 'q' is changed.

Although this isn't a command line solution, I'm surprised the Git GUI hasn't been suggested yet.

I use the command line 99% of the time, but in this case its either far to slow (hence the original question), or you don't know what you are about to delete when resorting to some lengthy, but clever shell manipulation.

The UI solves this issue since you can quickly check off the branches you want removed, and be reminded of ones you want to keep, without having to type a command for every branch.

From the UI go to Branch --> Delete and Ctrl+Click the branches you want to delete so they are highlighted. If you want to be sure they are merged into a branch (such as dev), under Delete Only if Merged Into set Local Branch to dev. Otherwise, set it to Always to ignore this check.

If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.

As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).

So 30 minutes is 30 / 1440 = 0.02083333.

Final code:

$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });

I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.

Jelly Bean adds support for this with the ActivityOptions.makeCustomAnimation() method. Of course, since it's only on Jelly Bean, it's pretty much worthless for practical purposes.

I needed to do a count of a very complex query with many joins. I was using the joins as filters, so I only wanted to know the count of the actual objects. count() was insufficient, but I found the answer in the docs here:

http://docs.sqlalchemy.org/en/latest/orm/tutorial.html

The code would look something like this (to count user objects):

from sqlalchemy import func

session.query(func.count(User.id)).scalar() 

I tried ng remove component Comp_Name also ng distroy component but it is not yet supported by angular so the best option for now is to manually remove it from the folder structure.

This exception may occurs when the activity which manages your fragments was stoped and you try to open it again, so in this case the NavHostFragment will be not reconized by activity which has losing the state. To fix it try to finish the cycle life of your activity in order to reload the NavHostFragment by the FrgamentManager again.

Inside your Activity where you manage your fragments put the below :

@Override
protected void onStop() {
    super.onStop();
    this.finishActivity(0);
}

I has similar problem in context of Stripe:

Error: Stripe no longer supports API requests made with TLS 1.0. Please initiate HTTPS connections with TLS 1.2 or later. You can learn more about this at https://stripe.com/blog/upgrading-tls.

Forcing TLS 1.2 using CURL parameter is temporary solution or even it can't be applied because of lack of room to place an update. By default TLS test function https://gist.github.com/olivierbellone/9f93efe9bd68de33e9b3a3afbd3835cf showed following configuration:

SSL version: NSS/3.21 Basic ECC
SSL version number: 0
OPENSSL_VERSION_NUMBER: 1000105f
TLS test (default): TLS 1.0
TLS test (TLS_v1): TLS 1.2
TLS test (TLS_v1_2): TLS 1.2

I updated libraries using following command:

yum update nss curl openssl

and then saw this:

SSL version: NSS/3.21 Basic ECC
SSL version number: 0
OPENSSL_VERSION_NUMBER: 1000105f
TLS test (default): TLS 1.2
TLS test (TLS_v1): TLS 1.2
TLS test (TLS_v1_2): TLS 1.2

Please notice that default TLS version changed to 1.2! That globally solved problem. This will help PayPal users too: https://www.paypal.com/au/webapps/mpp/tls-http-upgrade (update before end of June 2017)

You should make your thread support interrupts. Basically, you can call yourThread.interrupt() to stop the thread and, in your run() method you'd need to periodically check the status of Thread.interrupted()

There is a good tutorial here.

You don't mention if it has to be batch only, but if you can use ROBOCOPY, try this:

ROBOCOPY C:\Source C:\Destination data.zip info.txt /E

EDIT: Changed the /S parameter to /E to include empty folders.

Sending Data:

First make your serializable data by implement Serializable to your data class

public class YourDataClass implements Serializable {
String someText="Some text";
}

Then put it into intent

YourDataClass yourDataClass=new YourDataClass();
Intent intent = new Intent(getApplicationContext(),ReceivingActivity.class);
intent.putExtra("value",yourDataClass);
startActivity(intent);

Receiving Data:

YourDataClass yourDataClass=(YourDataClass)getIntent().getSerializableExtra("value");

This can be another way to do it and validate nulls

DataControlField dataControlField = UsersGrid.Columns.Cast<DataControlField>().SingleOrDefault(x => x.HeaderText == "Email");
            if (dataControlField != null)
                dataControlField.Visible = false;

Don't put the DB::insert() inside of the Schema::create(), because the create method has to finish making the table before you can insert stuff. Try this instead:

public function up()
{
    // Create the table
    Schema::create('users', function($table){
        $table->increments('id');
        $table->string('email', 255);
        $table->string('password', 64);
        $table->boolean('verified');
        $table->string('token', 255);
        $table->timestamps();
    });

    // Insert some stuff
    DB::table('users')->insert(
        array(
            'email' => '[email protected]',
            'verified' => true
        )
    );
}

If you plan to use Sphinx to document your code, it is capable of producing nicely formatted HTML docs for your parameters with their 'signatures' feature. http://sphinx-doc.org/domains.html#signatures

Confirm in API documentation http://api.jquery.com/jQuery.each/ say:

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

and this is my example http://jsfiddle.net/r6jqP/

(function($){
    $('#go').on('click',function(){
        var i=0,
            all=0;
        $('li').each(function(){
             all++;
             if($('#mytext').val()=='continue')return true;
             i++;
             if($('#mytext').val()==$(this).html()){
                 return false;
             }
        });
        alert('Iterazione : '+i+' to '+all);
    });
}(jQuery));

Try this: TO_DATE('2011-07-28T23:54:14Z', 'YYYY-MM-DD"T"HH24:MI:SS"Z"')

In addition to several other points mentioned already:

Less surprise

that is, it is much easier to see what a piece of code will do do exactly . In C++ you need to approach guru level to be able to know exactly what code the compiler generates (try a combination of templates, multiple inheritance, auto generated constructors, virtual functions and mix in a bit of namespace magic and argument dependent lookup).

In many cases this magic is nice, but for example in real-time systems it can really screw up your day.

I was also faced the same issue with mongodb 2.6.

What solved my problem was I just run mongod --repair command

and then start mongod.exe

It's worked for me

One of the (optional) arguments to the JVM is the stack size. It's -Xss. I don't know what the default value is, but if the total amount of stuff on the stack exceeds that value, you'll get that error.

Generally, infinite recursion is the cause of this, but if you were seeing that, your stack trace would have more than 5 frames.

Try adding a -Xss argument (or increasing the value of one) to see if this goes away.
