Programs & Examples On #Url obsfucation

I had some trouble with this, and finally I chose to create my own solution. Without using regular expression engine:

function contains($text, $word)
{
    $found = false;
    $spaceArray = explode(' ', $text);

    $nonBreakingSpaceArray = explode(chr(160), $text);

    if (in_array($word, $spaceArray) ||
        in_array($word, $nonBreakingSpaceArray)
       ) {

        $found = true;
    }
    return $found;
 }

You may notice that the previous solutions are not an answer for the word being used as a prefix for another. In order to use your example:

$a = 'How are you?';
$b = "a skirt that flares from the waist";
$c = "are";

With the samples above, both $a and $b contains $c, but you may want your function to tell you that only $a contains $c.

Try using rextract. It will let you extract text using a regular expression and reformat it.

Example:

$ echo "This is 02G05 a test string 20-Jul-2012" | ./rextract '([\d]+G[\d]+)' '${1}'

2G05

just like pure js do preventdefault : in class you should like this create a handler method :

handler(event) {
    event.preventDefault();
    console.log(event);
}

Protect/Lock Excel VBA Code:

When we write VBA code it is often desired to have the VBA Macro code not visible to end-users. This is to protect your intellectual property and/or stop users messing about with your code. Just be aware that Excel's protection ability is far from what would be considered secure. There are also many VBA Password Recovery [tools] for sale on the www.

To protect your code, open the Excel Workbook and go to Tools>Macro>Visual Basic Editor (Alt+F11). Now, from within the VBE go to Tools>VBAProject Properties and then click the Protection page tab and then check "Lock project from viewing" and then enter your password and again to confirm it. After doing this you must save, close & reopen the Workbook for the protection to take effect.

(Emphasis mine)

Seems like your best bet. It won't stop people determined to steal your code but it's enough to stop casual pirates.

Remember, even if you were able to distribute a compiled copy of your code there'd be nothing to stop people decompiling it.

I just found 0(zero) and shift+0 works on vim.

Try this:

List<string> names = new List<string>("Tom,Scott,Bob".Split(','));
names.Reverse();

I got here because I was concerned that cr-lfs that I specified in C# strings were not being shown in SQl Server Management Studio query responses.

It turns out, they are there, but are not being displayed.

To "see" the cr-lfs, use the print statement like:

declare @tmp varchar(500)    
select @tmp = msgbody from emailssentlog where id=6769;
print @tmp

be sure, that if the declarations for the pipe are done in one module, while you are using the pipe inside another module, you should provide correct imports/declarations at the current module under which is the class where you are using the pipe. In my case that was the reason for the pipe miss

the quick fix is to assign your variable to null at the top of your code

$user_location = null;

Dyamic date BETWEEN sql query

var startDate = '2019-08-22';
var Enddate = '2019-10-22'
     let sql = "SELECT * FROM Cases WHERE created_at BETWEEN '?' AND '?'";
     const users = await mysql.query( sql, [startDate, Enddate]);

import/export is now doing the job with ES6. I still tend to prefix not exported functions with _ if most of my functions are exported.

If you export only a class (like in angular projects), it's not needed at all.

export class MyOpenClass{

    open(){
         doStuff()
         this._privateStuff()
         return close();
    }

    _privateStuff() { /* _ only as a convention */} 

}

function close(){ /*... this is really private... */ }

To complete the picture, since -Werror might considered too "invasive",
for gcc (and llvm) a more precise solution is to transform just this warning in an error, using the option:

-Werror=implicit-function-declaration

See Make one gcc warning an error?

Regarding general use of -Werror: Of course, having warningless code is recommendable, but in some stage of development it might slow down the prototyping.

<?php
$conn=mysqli_connect("127.0.0.1:3306","root","","admin");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="select count('user_id') from login_user";
$result=mysqli_query($conn,$sql);
$row=mysqli_fetch_array($result);
echo "$row[0]";
mysqli_close($conn);
?>

Still having problem visit my tutorial http://www.studentstutorial.com/php/php-count-rows.php

A command-line process such cmd.exe or mysql.exe will usually read (and execute) whatever you (the user) type in (at the keyboard).

To mimic that, I think you want to use the RedirectStandardInput property: http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandardinput.aspx

It looks like sklearn requires the data shape of (row number, column number). If your data shape is (row number, ) like (999, ), it does not work. By using numpy.reshape(), you should change the shape of the array to (999, 1), e.g. using

data=data.reshape((999,1))

In my case, it worked with that.

Trusting all certificates was no real alternative for me, so I did the following to get HttpsURLConnection to trust a new certificate (see also http://nelenkov.blogspot.jp/2011/12/using-custom-certificate-trust-store-on.html).

1. Get the certificate; I got this done by exporting the certificate in Firefox (click on the little lock icon, get certificate details, click export), then used portecle to export a truststore (BKS).

2. Load the Truststore from /res/raw/geotrust_cert.bks with the following code:

       final KeyStore trustStore = KeyStore.getInstance("BKS");
       final InputStream in = context.getResources().openRawResource(
               R.raw.geotrust_cert);
       trustStore.load(in, null);
   
       final TrustManagerFactory tmf = TrustManagerFactory
               .getInstance(TrustManagerFactory.getDefaultAlgorithm());
       tmf.init(trustStore);
   
       final SSLContext sslCtx = SSLContext.getInstance("TLS");
       sslCtx.init(null, tmf.getTrustManagers(),
               new java.security.SecureRandom());
   
       HttpsURLConnection.setDefaultSSLSocketFactory(sslCtx
               .getSocketFactory());
   

In my case, Incorrect string value: '\xCC\x88'..., the problem was that an o-umlaut was in its decomposed state. This question-and-answer helped me understand the difference between o¨ and ö. In PHP, the fix for me was to use PHP's Normalizer library. E.g., Normalizer::normalize('o¨', Normalizer::FORM_C).

I have tried this and it worked:

define PROPp_START_DT = TO_DATE('01-SEP-1999')

select * from proposal where prop_start_dt = &PROPp_START_DT

I believe you are looking for setInterval()

I ran into this problem and fixed it by closing the input and output streams before closing the socket. Now I can disconnect and connect again with no issues.

https://stackoverflow.com/a/3039807/5688612

In Kotlin:

fun disconnect() {
    bluetoothSocket.inputStream.close()
    bluetoothSocket.outputStream.close()
    bluetoothSocket.close()
}

If the form starts up first, in the form Load handler we can instantiate a copy of our class. We can have properties that reference whichever controls we want to reference. Pass the reference to the form 'this' to the constructor for the class.

public partial class Form1 : Form
{
    public ListView Lv
    {
        get { return lvProcesses; }
    }

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        Utilities ut = new Utilities(this);
    }
}

In your class, the reference from the form is passed into the constructor and stored as a private member. This form reference can be used to access the form's properties.

class Utilities
{
    private Form1 _mainForm;
    public Utilities(Form1 mainForm)
    {
        _mainForm = mainForm;
        _mainForm.Lv.Items.Clear();
    }
}

if you happen to not have a graphical interface available you can also print out the commit graph on the command line:

git log --oneline --graph --decorate --all

if this command complains with an invalid option --oneline, use:

git log --pretty=oneline --graph --decorate --all

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

$("form > .form-group > i").click(function(){
    $('#icon').toggleClass('fa-eye fa-eye-slash');

    if($('#icon').hasClass('fa-eye')){
        $('#Password1').attr('type','text');
    } else {
        $('#Password1').attr('type','password');
    }
});

all examples are good....Here is nice visual illustration... source courtesy : DataFlair training of spark

Map : A map is a transformation operation in Apache Spark. It applies to each element of RDD and it returns the result as new RDD. In the Map, operation developer can define his own custom business logic. The same logic will be applied to all the elements of RDD.

Spark RDD map function takes one element as input process it according to custom code (specified by the developer) and returns one element at a time. Map transforms an RDD of length N into another RDD of length N. The input and output RDDs will typically have the same number of records.

Example of map using scala :

val x = spark.sparkContext.parallelize(List("spark", "map", "example",  "sample", "example"), 3)
val y = x.map(x => (x, 1))
y.collect
// res0: Array[(String, Int)] = 
//    Array((spark,1), (map,1), (example,1), (sample,1), (example,1))

// rdd y can be re writen with shorter syntax in scala as 
val y = x.map((_, 1))
y.collect
// res1: Array[(String, Int)] = 
//    Array((spark,1), (map,1), (example,1), (sample,1), (example,1))

// Another example of making tuple with string and it's length
val y = x.map(x => (x, x.length))
y.collect
// res3: Array[(String, Int)] = 
//    Array((spark,5), (map,3), (example,7), (sample,6), (example,7))

FlatMap :

A flatMap is a transformation operation. It applies to each element of RDD and it returns the result as new RDD. It is similar to Map, but FlatMap allows returning 0, 1 or more elements from map function. In the FlatMap operation, a developer can define his own custom business logic. The same logic will be applied to all the elements of the RDD.

What does "flatten the results" mean?

A FlatMap function takes one element as input process it according to custom code (specified by the developer) and returns 0 or more element at a time. flatMap() transforms an RDD of length N into another RDD of length M.

Example of flatMap using scala :

val x = spark.sparkContext.parallelize(List("spark flatmap example",  "sample example"), 2)

// map operation will return Array of Arrays in following case : check type of res0
val y = x.map(x => x.split(" ")) // split(" ") returns an array of words
y.collect
// res0: Array[Array[String]] = 
//  Array(Array(spark, flatmap, example), Array(sample, example))

// flatMap operation will return Array of words in following case : Check type of res1
val y = x.flatMap(x => x.split(" "))
y.collect
//res1: Array[String] = 
//  Array(spark, flatmap, example, sample, example)

// RDD y can be re written with shorter syntax in scala as 
val y = x.flatMap(_.split(" "))
y.collect
//res2: Array[String] = 
//  Array(spark, flatmap, example, sample, example)

All the references to Apache Commons are fine (and that is what most people use) but I think the Guava equivalent, Joiner, has a much nicer API.

You can do the simple join case with

Joiner.on(" and ").join(names)

but also easily deal with nulls:

Joiner.on(" and ").skipNulls().join(names);

or

Joiner.on(" and ").useForNull("[unknown]").join(names);

and (useful enough as far as I'm concerned to use it in preference to commons-lang), the ability to deal with Maps:

Map<String, Integer> ages = .....;
String foo = Joiner.on(", ").withKeyValueSeparator(" is ").join(ages);
// Outputs:
// Bill is 25, Joe is 30, Betty is 35

which is extremely useful for debugging etc.

Suppose you want to display some live feed content (say livefeed.txt) on you web page without any page refresh then the following simplified example is for you.

In the below html file, the live data gets updated on the div element of id "liveData"

index.html

<!DOCTYPE html>
<html>
<head>
    <title>Live Update</title>
    <meta charset="UTF-8">
    <script type="text/javascript" src="autoUpdate.js"></script>
</head>
<div id="liveData">
    <p>Loading Data...</p>
</div>
</body>
</html>

Below autoUpdate.js reads the live data using XMLHttpRequest object and updates the html div element on every 1 second. I have given comments on most part of the code for better understanding.

autoUpdate.js

window.addEventListener('load', function()
{
    var xhr = null;

    getXmlHttpRequestObject = function()
    {
        if(!xhr)
        {               
            // Create a new XMLHttpRequest object 
            xhr = new XMLHttpRequest();
        }
        return xhr;
    };

    updateLiveData = function()
    {
        var now = new Date();
        // Date string is appended as a query with live data 
        // for not to use the cached version 
        var url = 'livefeed.txt?' + now.getTime();
        xhr = getXmlHttpRequestObject();
        xhr.onreadystatechange = evenHandler;
        // asynchronous requests
        xhr.open("GET", url, true);
        // Send the request over the network
        xhr.send(null);
    };

    updateLiveData();

    function evenHandler()
    {
        // Check response is ready or not
        if(xhr.readyState == 4 && xhr.status == 200)
        {
            dataDiv = document.getElementById('liveData');
            // Set current data text
            dataDiv.innerHTML = xhr.responseText;
            // Update the live data every 1 sec
            setTimeout(updateLiveData(), 1000);
        }
    }
});

For testing purpose: Just write some thing in the livefeed.txt - You will get updated the same in index.html without any refresh.

livefeed.txt

Hello
World
blah..
blah..

Note: You need to run the above code on the web server (ex: http://localhost:1234/index.html) not as a client html file (ex: file:///C:/index.html).

The below code worked for me :)

window.open('your current page URL', '_self', '');
window.close();

Based on Henk's answer I have been able to come up with the specific domain, the method I want to allow and also the header I want to enable CORS for:

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>
         options.AddPolicy("AllowSpecific", p => p.WithOrigins("http://localhost:1233")
                                                   .WithMethods("GET")
                                                   .WithHeaders("name")));
    services.AddMvc();
}

usage:

[EnableCors("AllowSpecific")]

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.

Do simultaneous work on the dev branch. What happens is that in your scenario the feature branch moves forward from the tip of the dev branch, but the dev branch does not change. It's easier to draw as a straight line, because it can be thought of as forward motion. You made it to point A on dev, and from there you simply continued on a parallel path. The two branches have not really diverged.

Now, if you make a commit on dev, before merging, you will again begin at the same commit, A, but now features will go to C and dev to B. This will show the split you are trying to visualize, as the branches have now diverged.

*-----*Dev-------*Feature

Versus

       /----*DevB
*-----*DevA
       \----*FeatureC

you should use magic methods __Set and __get. Simple example:

class Foo
{
    //This array stores your properties
private $content = array();

public function __set($key, $value)
{
            //Perform data validation here before inserting data
    $this->content[$key] = $value;
    return $this;
}

public function __get($value)
{       //You might want to check that the data exists here
    return $this->$content[$value];
}

}

Of course, don't use this example as this : no security at all :)

EDIT : seen your comments, here could be an alternative based on reflection and a decorator :

 class Foo
 {
private $content = array();
private $stdInstance;

public function __construct($stdInstance)
{
    $this->stdInstance = $stdInstance;
}

public function __set($key, $value)
{
    //Reflection for the stdClass object
    $ref = new ReflectionClass($this->stdInstance);
    //Fetch the props of the object

    $props = $ref->getProperties();

    if (in_array($key, $props)) {
        $this->stdInstance->$key = $value;
    } else {
        $this->content[$key] = $value;
    }
    return $this;
}

public function __get($value)
{
    //Search first your array as it is faster than using reflection
    if (array_key_exists($value, $this->content))
    {
        return $this->content[$value];
    } else {
        $ref = new ReflectionClass($this->stdInstance);

        //Fetch the props of the object
        $props = $ref->getProperties();

        if (in_array($value, $props)) {

        return $this->stdInstance->$value;
    } else {
        throw new \Exception('No prop in here...');
    }
}
 }
}

PS : I didn't test my code, just the general idea...

Isn't this the path you are looking for?

C:\Program Files\nodejs\node_modules\npm\npmrc

I know that npm outputs that , but the global folder is the folder where node.js is installed and all the modules are.

Cascade will work when you delete something on table Courses. Any record on table BookCourses that has reference to table Courses will be deleted automatically.

But when you try to delete on table BookCourses only the table itself is affected and not on the Courses

follow-up question: why do you have CourseID on table Category?

Maybe you should restructure your schema into this,

CREATE TABLE Categories 
(
  Code CHAR(4) NOT NULL PRIMARY KEY,
  CategoryName VARCHAR(63) NOT NULL UNIQUE
);

CREATE TABLE Courses 
(
  CourseID INT NOT NULL PRIMARY KEY,
  BookID INT NOT NULL,
  CatCode CHAR(4) NOT NULL,
  CourseNum CHAR(3) NOT NULL,
  CourseSec CHAR(1) NOT NULL,
);

ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)
REFERENCES Categories(Code)
ON DELETE CASCADE;

You should check if the POST['username'] is defined. Use this above:

$username = "";

if(isset($_POST['username'])){
    $username = $_POST['username'];
}

"SELECT password FROM users WHERE username='".$username."'"

"FirstLine" + "<br/>" "SecondLine"

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

You can call the super class's constructor like this

class A(object):
    def __init__(self, number):
        print "parent", number

class B(A):
    def __init__(self):
        super(B, self).__init__(5)

b = B()

NOTE:

This will work only when the parent class inherits object

I've just wasted an hour on this. I tried everything - it turned out (and I can hardly believe this) that giving my cancel button and element id of cancel meant that any attempt to prevent event propagation would fail! I guess an HTML page must treat this as someone pressing ESC?

Follow the next steps:

1. Open the app.config and comment on the connection string (save file)
2. Open the edmx (go to properties, the connection string should be blank), close the edmx file again
3. Open the app.config and uncomment the connection string (save file)
4. Open the edmx, go to properties, you should see the connection string uptated!!

You can use "

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

Many time this error is caused when you update a product in your custom module's observer as shown below.

class [NAMESPACE]_[MODULE NAME]_Model_Observer
{
    /**
     * Flag to stop observer executing more than once
     *
     * @var static bool
     */
    static protected $_singletonFlag = false;

    public function saveProductData(Varien_Event_Observer $observer)
    {
        if (!self::$_singletonFlag) {
            self::$_singletonFlag = true;

            $product = $observer->getEvent()->getProduct();
             //do stuff to the $product object
            // $product->save();  // commenting out this line prevents the error
            $product->getResource()->save($product);
    }
} 

Hence whenever you save your product after updating some properties in your module's observer use $product->getResource()->save($product) instead of $product->save()

The javascript below works for me. Credits to @artur.k.space.

function ColabReconnect() {
    var dialog = document.querySelector("colab-dialog.yes-no-dialog");
    var dialogTitle = dialog && dialog.querySelector("div.content-area>h2");
    if (dialogTitle && dialogTitle.innerText == "Runtime disconnected") {
        dialog.querySelector("paper-button#ok").click();
        console.log("Reconnecting...");
    } else {
        console.log("ColabReconnect is in service.");
    }
}
timerId = setInterval(ColabReconnect, 60000);

In the Colab notebook, click on Ctrl + Shift + the i key simultaneously. Copy and paste the script into the prompt line. Then hit Enter before closing the editor.

By doing so, the function will check every 60 seconds to see if the onscreen connection dialog is shown, and if it is, the function would then click the ok button automatically for you.

simple if u are using php Just append the current time at the end of the css like

<link href="css/name.css?<?php echo 
time(); ?>" rel="stylesheet">

So now everytime u reload whatever it is , the time changes and browser thinks its a different file since the last bit keeps changing.... U can do this for any file u force the browser to always refresh using whatever scripting language u want

This is how I solved this problem

$scope.downloadPDF = function () {
    var link = document.createElement("a");
    link.setAttribute("href",  "path_to_pdf_file/pdf_filename.pdf");
    link.setAttribute("download", "download_name.pdf");
    document.body.appendChild(link); // Required for FF
    link.click(); // This will download the data file named "download_name.pdf"
}

If you already have node installed, your path variable is set up and you suddenly start getting this error; try updating to the latest version.

This worked for me going from 6.9.2 to 6.10.

You can use this:

bankHoliday= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   month -= 1#Takes away the numbers from the months, as months start at 1 (January) not at 0. There is no 0 month.
   print(bankHoliday[month])

bank_holiday(int(input("Which month would you like to check out: ")))

Try with an address that is not gmail. They do not allow (as far as i know) smpt access to send mail from. I was doing a simple mail program last week and they also dont use default ports to send from and require that you transport across https

You were missing the small icon. I did the same mistake and the above step resolved it.

As per the official documentation: A Notification object must contain the following:

1. A small icon, set by setSmallIcon()

2. A title, set by setContentTitle()

3. Detail text, set by setContentText()

4. On Android 8.0 (API level 26) and higher, a valid notification channel ID, set by setChannelId() or provided in the NotificationCompat.Builder constructor when creating a channel.

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

That should work via HTTPRewriteModule.

Example rewrite from www.example.com to example.com:

server {    
    server_name www.example.com;    
    rewrite ^ http://example.com$request_uri? permanent; 
}

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

https://msdn.microsoft.com/en-us/library/dd465326(VS.100).aspx

You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.

So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filters.

Using Static will solve your problem (with some other stuff to initialize old_value properly:

Private Sub Worksheet_Change(ByVal Target As Range)
    Static old_value As String
    Dim inited as Boolean 'Used to detect first call and fill old_value
    Dim new_value As String
    If Not Intersect(cell, Range("cell_of_interest")) Is Nothing Then
         new_value = Range("cell_of_interest").Value
         If Not inited Then
             inited = True
         Else
            Call DoFoo (old_value, new_value)
        End If
        old_value = new_value
    Next cell
End Sub

In workbook code, force call of Worksheet_change to fill old_value:

Private Sub Private Sub Workbook_Open()
     SheetX.Worksheet_Change SheetX.Range("cell_of_interest")
End Sub

Note, however, that ANY solution based in VBA variables (including dictionary and another more sophisticate methods) will fail if you stop (Reset) running code (eg. while creating new macros, debugging some code, ...). To avoid such, consider using alternative storage methods (hidden worksheet, for example).

I think you can use the TimeZoneInfo....to convert the datetime....

    static void Main(string[] args)
    {
        long time = 1310522400000;
        DateTime dt_1970 = new DateTime(1970, 1, 1);
        long tricks_1970 = dt_1970.Ticks;
        long time_tricks = tricks_1970 + time * 10000;
        DateTime dt = new DateTime(time_tricks);

        Console.WriteLine(dt.ToShortDateString()); // result : 7/13
        dt = TimeZoneInfo.ConvertTimeToUtc(dt);

        Console.WriteLine(dt.ToShortDateString());  // result : 7/12
        Console.Read();
    }

Sometimes brew update fails on me because one package doesn't download properly. So you can just upgrade a specific library like this:

I would use the jQuery validation plugin for a few reasons.

You validated, ok great, now what? You need to display the error, handle erasing it when it is valid, displaying how many errors total perhaps? There are lots of things it can handle for you, no need to re-invent the wheel.

Also, another huge benefit is it's hosted on a CDN, the current version at the time of this answer can be found here: http://www.asp.net/ajaxLibrary/CDNjQueryValidate16.ashx This means faster load times for the client.

Use timedelta.total_seconds().

>>> import datetime
>>> datetime.timedelta(seconds=24*60*60).total_seconds()

'Effectively final' is a variable which would not give compiler error if it were to be appended by 'final'

From a article by 'Brian Goetz',

Informally, a local variable is effectively final if its initial value is never changed -- in other words, declaring it final would not cause a compilation failure.

For Python 3:

{k:v for k,v in d.items() if v}

what about using unwrap()

<div class="parent">
<p class="child">
</p>
</div>

after using - $(".child").unwrap() - it will be;

<p class="child">
</p>

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

If it's published, you can't delete it (without risking being tarred and feathered, that is). The 'Git way' is to do:

The sane thing. Just admit you screwed up, and use a different name. Others have already seen one tag-name, and if you keep the same name, you may be in the situation that two people both have "version X", but they actually have different "X"'s. So just call it "X.1" and be done with it.

Alternatively,

The insane thing. You really want to call the new version "X" too, even though others have already seen the old one. So just use git-tag -f again, as if you hadn't already published the old one.

It's so insane because:

Git does not (and it should not) change tags behind users back. So if somebody already got the old tag, doing a git-pull on your tree shouldn't just make them overwrite the old one.

If somebody got a release tag from you, you cannot just change the tag for them by updating your own one. This is a big security issue, in that people MUST be able to trust their tag-names. If you really want to do the insane thing, you need to just fess up to it, and tell people that you messed up.

In 'for' loop, local variable is still lives after each loop. In 'each' loop, local variable refreshes after each loop.

The simplest way would be to use FOpen or one of FOpen's Wrappers.

$page = file_get_contents("http://www.domain.com/filename");

This does require FOpen which some web hosts disable and some web hosts will allow FOpen, but not allow access to external files. You may want to check where you are going to run the script to see if you have access to External FOpen.

If you can use UITableViewController, you get the functionality for free. Sometimes, however, this is not an option, specifically if you need multiple views not just the UITableView.

Some of the solutions presented here don't work on iOS =4, some don't work on iPad or in landscape mode, some don't work for Bluetooth keyboards (where we don't want any scrolling), some don't work when switching between multiple text fields. So if you choose any solution, make sure to test these cases. This is the solution we use used in InAppSettingsKit:

- (void)_keyboardWillShow:(NSNotification*)notification {
    if (self.navigationController.topViewController == self) {
        NSDictionary* userInfo = [notification userInfo];

        // we don't use SDK constants here to be universally compatible with all SDKs = 3.0
        NSValue* keyboardFrameValue = [userInfo objectForKey:@"UIKeyboardBoundsUserInfoKey"];
        if (!keyboardFrameValue) {
            keyboardFrameValue = [userInfo objectForKey:@"UIKeyboardFrameEndUserInfoKey"];
        }

        // Reduce the tableView height by the part of the keyboard that actually covers the tableView
        CGRect windowRect = [[UIApplication sharedApplication] keyWindow].bounds;
        if (UIInterfaceOrientationLandscapeLeft == self.interfaceOrientation ||UIInterfaceOrientationLandscapeRight == self.interfaceOrientation ) {
            windowRect = IASKCGRectSwap(windowRect);
        }
        CGRect viewRectAbsolute = [_tableView convertRect:_tableView.bounds toView:[[UIApplication sharedApplication] keyWindow]];
        if (UIInterfaceOrientationLandscapeLeft == self.interfaceOrientation ||UIInterfaceOrientationLandscapeRight == self.interfaceOrientation ) {
            viewRectAbsolute = IASKCGRectSwap(viewRectAbsolute);
        }
        CGRect frame = _tableView.frame;
        frame.size.height -= [keyboardFrameValue CGRectValue].size.height - CGRectGetMaxY(windowRect) + CGRectGetMaxY(viewRectAbsolute);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
        [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];
        _tableView.frame = frame;
        [UIView commitAnimations];

        UITableViewCell *textFieldCell = (id)((UITextField *)self.currentFirstResponder).superview.superview;
        NSIndexPath *textFieldIndexPath = [_tableView indexPathForCell:textFieldCell];

        // iOS 3 sends hide and show notifications right after each other
        // when switching between textFields, so cancel -scrollToOldPosition requests
        [NSObject cancelPreviousPerformRequestsWithTarget:self];

        [_tableView scrollToRowAtIndexPath:textFieldIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
    }
}

- (void) scrollToOldPosition {
  [_tableView scrollToRowAtIndexPath:_topmostRowBeforeKeyboardWasShown atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

- (void)_keyboardWillHide:(NSNotification*)notification {
    if (self.navigationController.topViewController == self) {
        NSDictionary* userInfo = [notification userInfo];

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
        [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]];
        _tableView.frame = self.view.bounds;
        [UIView commitAnimations];

        [self performSelector:@selector(scrollToOldPosition) withObject:nil afterDelay:0.1];
    }
}   

Here's the full code of the class in InAppSettingsKit. To test it, use the "Complete List" child pane where you can test the scenarios mentioned above.

Just to add up my bit:
Remember, you're gonna need to have at least 2 areas in your MVC application to get the routeValues: { area="" } working; otherwise the area value will be used as a query-string parameter and you link will look like this: /?area=

If you don't have at least 2 areas, you can fix this behavior by:
1. editing the default route in RouteConfig.cs like this:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { area = "", controller = "Home", action = "Index", id = UrlParameter.Optional }
);

OR
2. Adding a dummy area to your MVC project.

Run vim from the terminal. For the basics, you're advised to run the command vimtutor.

# On your terminal command line:
$ vim

If you have a specific file to edit, pass it as an argument.

$ vim yourfile.cpp

Likewise, launch the tutorial

$ vimtutor

The foreach underhood is creating the iterator, calling hasNext() and calling next() to get the value; The issue with the performance comes only if you are using something that implements the RandomomAccess.

for (Iterator<CustomObj> iter = customList.iterator(); iter.hasNext()){
   CustomObj custObj = iter.next();
   ....
}

Performance issues with the iterator-based loop is because it is:

1. allocating an object even if the list is empty (Iterator<CustomObj> iter = customList.iterator(););
2. iter.hasNext() during every iteration of the loop there is an invokeInterface virtual call (go through all the classes, then do method table lookup before the jump).
3. the implementation of the iterator has to do at least 2 fields lookup in order to make hasNext() call figure the value: #1 get current count and #2 get total count
4. inside the body loop, there is another invokeInterface virtual call iter.next(so: go through all the classes and do method table lookup before the jump) and as well has to do fields lookup: #1 get the index and #2 get the reference to the array to do the offset into it (in every iteration).

A potential optimiziation is to switch to an index iteration with the cached size lookup:

for(int x = 0, size = customList.size(); x < size; x++){
  CustomObj custObj = customList.get(x);
  ...
}

Here we have:

1. one invokeInterface virtual method call customList.size() on the initial creation of the for loop to get the size
2. the get method call customList.get(x) during the body for loop, which is a field lookup to the array and then can do the offset into the array

We reduced a ton of method calls, field lookups. This you don't want to do with LinkedList or with something that is not a RandomAccess collection obj, otherwise the customList.get(x) is gonna turn into something that has to traverse the LinkedList on every iteration.

This is perfect when you know that is any RandomAccess based list collection.

We had some code here (in VS2005 and C#2.0) where the previous engineers went out of their way to use list.ForEach( delegate(item) { foo;}); instead of foreach(item in list) {foo; }; for all the code that they wrote. e.g. a block of code for reading rows from a dataReader.

I still don't know exactly why they did this.

The drawbacks of list.ForEach() are:

• It is more verbose in C# 2.0. However, in C# 3 onwards, you can use the "=>" syntax to make some nicely terse expressions.

• It is less familiar. People who have to maintain this code will wonder why you did it that way. It took me awhile to decide that there wasn't any reason, except maybe to make the writer seem clever (the quality of the rest of the code undermined that). It was also less readable, with the "})" at the end of the delegate code block.

• See also Bill Wagner's book "Effective C#: 50 Specific Ways to Improve Your C#" where he talks about why foreach is preferred to other loops like for or while loops - the main point is that you are letting the compiler decide the best way to construct the loop. If a future version of the compiler manages to use a faster technique, then you will get this for free by using foreach and rebuilding, rather than changing your code.

• a foreach(item in list) construct allows you to use break or continue if you need to exit the iteration or the loop. But you cannot alter the list inside a foreach loop.

I'm surprised to see that list.ForEach is slightly faster. But that's probably not a valid reason to use it throughout , that would be premature optimisation. If your application uses a database or web service that, not loop control, is almost always going to be be where the time goes. And have you benchmarked it against a for loop too? The list.ForEach could be faster due to using that internally and a for loop without the wrapper would be even faster.

I disagree that the list.ForEach(delegate) version is "more functional" in any significant way. It does pass a function to a function, but there's no big difference in the outcome or program organisation.

I don't think that foreach(item in list) "says exactly how you want it done" - a for(int 1 = 0; i < count; i++) loop does that, a foreach loop leaves the choice of control up to the compiler.

My feeling is, on a new project, to use foreach(item in list) for most loops in order to adhere to the common usage and for readability, and use list.Foreach() only for short blocks, when you can do something more elegantly or compactly with the C# 3 "=>" operator. In cases like that, there may already be a LINQ extension method that is more specific than ForEach(). See if Where(), Select(), Any(), All(), Max() or one of the many other LINQ methods doesn't already do what you want from the loop.

In your specific case, you can set the containing a element to be:

a {
    display: block;
    text-align: center;
}

I think you need something like this....

b="HELLO,THERE,WORLD"
re.findall('[\w]+',b)

Which in Python3 will return

['HELLO', 'THERE', 'WORLD']

Another nice and useful solution is to create this kind of extension:

extension Array where Element: Equatable {

    @discardableResult mutating func remove(object: Element) -> Bool {
        if let index = index(of: object) {
            self.remove(at: index)
            return true
        }
        return false
    }

    @discardableResult mutating func remove(where predicate: (Array.Iterator.Element) -> Bool) -> Bool {
        if let index = self.index(where: { (element) -> Bool in
            return predicate(element)
        }) {
            self.remove(at: index)
            return true
        }
        return false
    }

}

In this way, if you have your array with custom objects:

let obj1 = MyObject(id: 1)
let obj2 = MyObject(id: 2)
var array: [MyObject] = [obj1, obj2]

array.remove(where: { (obj) -> Bool in
    return obj.id == 1
})
// OR
array.remove(object: obj2) 

One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.

For example:

background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.

Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:

background_label.image = background_image

static_cast is the first cast you should attempt to use. It does things like implicit conversions between types (such as int to float, or pointer to void*), and it can also call explicit conversion functions (or implicit ones). In many cases, explicitly stating static_cast isn't necessary, but it's important to note that the T(something) syntax is equivalent to (T)something and should be avoided (more on that later). A T(something, something_else) is safe, however, and guaranteed to call the constructor.

static_cast can also cast through inheritance hierarchies. It is unnecessary when casting upwards (towards a base class), but when casting downwards it can be used as long as it doesn't cast through virtual inheritance. It does not do checking, however, and it is undefined behavior to static_cast down a hierarchy to a type that isn't actually the type of the object.

const_cast can be used to remove or add const to a variable; no other C++ cast is capable of removing it (not even reinterpret_cast). It is important to note that modifying a formerly const value is only undefined if the original variable is const; if you use it to take the const off a reference to something that wasn't declared with const, it is safe. This can be useful when overloading member functions based on const, for instance. It can also be used to add const to an object, such as to call a member function overload.

const_cast also works similarly on volatile, though that's less common.

dynamic_cast is exclusively used for handling polymorphism. You can cast a pointer or reference to any polymorphic type to any other class type (a polymorphic type has at least one virtual function, declared or inherited). You can use it for more than just casting downwards – you can cast sideways or even up another chain. The dynamic_cast will seek out the desired object and return it if possible. If it can't, it will return nullptr in the case of a pointer, or throw std::bad_cast in the case of a reference.

dynamic_cast has some limitations, though. It doesn't work if there are multiple objects of the same type in the inheritance hierarchy (the so-called 'dreaded diamond') and you aren't using virtual inheritance. It also can only go through public inheritance - it will always fail to travel through protected or private inheritance. This is rarely an issue, however, as such forms of inheritance are rare.

reinterpret_cast is the most dangerous cast, and should be used very sparingly. It turns one type directly into another — such as casting the value from one pointer to another, or storing a pointer in an int, or all sorts of other nasty things. Largely, the only guarantee you get with reinterpret_cast is that normally if you cast the result back to the original type, you will get the exact same value (but not if the intermediate type is smaller than the original type). There are a number of conversions that reinterpret_cast cannot do, too. It's used primarily for particularly weird conversions and bit manipulations, like turning a raw data stream into actual data, or storing data in the low bits of a pointer to aligned data.

C-style cast and function-style cast are casts using (type)object or type(object), respectively, and are functionally equivalent. They are defined as the first of the following which succeeds:

• const_cast
• static_cast (though ignoring access restrictions)
• static_cast (see above), then const_cast
• reinterpret_cast
• reinterpret_cast, then const_cast

It can therefore be used as a replacement for other casts in some instances, but can be extremely dangerous because of the ability to devolve into a reinterpret_cast, and the latter should be preferred when explicit casting is needed, unless you are sure static_cast will succeed or reinterpret_cast will fail. Even then, consider the longer, more explicit option.

C-style casts also ignore access control when performing a static_cast, which means that they have the ability to perform an operation that no other cast can. This is mostly a kludge, though, and in my mind is just another reason to avoid C-style casts.

I'll use find command

find / -maxdepth 2 -iname 'tmp' -type d

as non superuser for the demo. It should complain 'Permission denied' when acessing / dir.

#!/bin/bash

echo "terminal:"
{ err="$(find / -maxdepth 2 -iname 'tmp' -type d 2>&1 1>&3 3>&- | tee /dev/stderr)"; } 3>&1 | tee /dev/fd/4 2>&1; out=$(cat /dev/fd/4)
echo "stdout:" && echo "$out"
echo "stderr:" && echo "$err"

that gives output:

terminal:
find: ‘/root’: Permission denied
/tmp
/var/tmp
find: ‘/lost+found’: Permission denied
stdout:
/tmp
/var/tmp
stderr:
find: ‘/root’: Permission denied
find: ‘/lost+found’: Permission denied

The terminal output has also /dev/stderr content the same way as if you were running that find command without any script. $out has /dev/stdout and $err has /dev/stderr content.

use:

#!/bin/bash

echo "terminal:"
{ err="$(find / -maxdepth 2 -iname 'tmp' -type d 2>&1 1>&3 3>&-)"; } 3>&1 | tee /dev/fd/4; out=$(cat /dev/fd/4)
echo "stdout:" && echo "$out"
echo "stderr:" && echo "$err"

if you don't want to see /dev/stderr in the terminal output.

terminal:
/tmp
/var/tmp
stdout:
/tmp
/var/tmp
stderr:
find: ‘/root’: Permission denied
find: ‘/lost+found’: Permission denied

Try changing the version of your react-native specified in your package.json (under dependencies - react-native) to the same as 'Native Version' shown in the error message. Then run 'npm install' again.

Add the file to a formData object, and set the Content-Type header to multipart/form-data.

var formData = new FormData();
var imagefile = document.querySelector('#file');
formData.append("image", imagefile.files[0]);
axios.post('upload_file', formData, {
    headers: {
      'Content-Type': 'multipart/form-data'
    }
})

The sexiest version by far is with format strings.

from datetime import datetime

print(f'{datetime.today():%Y-%m-%d}')

You can use the format option, as described in the documentation

$("#timePicker").datetimepicker({
  format: 'Y-m-d H:i'
});

When you push to a remote and you use the --set-upstream flag git sets the branch you are pushing to as the remote tracking branch of the branch you are pushing.

Adding a remote tracking branch means that git then knows what you want to do when you git fetch, git pull or git push in future. It assumes that you want to keep the local branch and the remote branch it is tracking in sync and does the appropriate thing to achieve this.

You could achieve the same thing with git branch --set-upstream-to or git checkout --track. See the git help pages on tracking branches for more information.

var sessionVal = '@Session["EnergyUnit"]';
alert(sessionVal);

I think this would be a better way to do it in Swift:

func filterContentForSearchText(searchText:NSString, scope:NSString)
{
   searchResults = recipes.filter { name.rangeOfString(searchText) != nil  }
}

try this,

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_sample, menu);
    super.onCreateOptionsMenu(menu,inflater);
}

Finally, in onCreateView method, add this line to make the options appear in your Toolbar

setHasOptionsMenu(true);

It's not a good question for S.O. (it's not a specific programming question), but it's not a bad question in general.

If you think it's trivial: what about read-time vs compile-time, and when is this a useful distinction to make? What about languages where the compiler is available at runtime? Guy Steele (no dummy, he) wrote 7 pages in CLTL2 about EVAL-WHEN, which CL programmers can use to control this. 2 sentences are barely enough for a definition, which itself is far short of an explanation.

In general, it's a tough problem that language designers have seemed to try to avoid. They often just say "here's a compiler, it does compile-time things; everything after that is run-time, have fun". C is designed to be simple to implement, not the most flexible environment for computation. When you don't have the compiler available at runtime, or the ability to easily control when an expression is evaluated, you tend to end up with hacks in the language to fake common uses of macros, or users come up with Design Patterns to simulate having more powerful constructs. A simple-to-implement language can definitely be a worthwhile goal, but that doesn't mean it's the end-all-be-all of programming language design. (I don't use EVAL-WHEN much, but I can't imagine life without it.)

And the problemspace around compile-time and run-time is huge and still largely unexplored. That's not to say S.O. is the right place to have the discussion, but I encourage people to explore this territory further, especially those who have no preconceived notions of what it should be. The question is neither simple nor silly, and we could at least point the inquisitor in the right direction.

Unfortunately, I don't know any good references on this. CLTL2 talks about it a bit, but it's not great for learning about it.

Here is how I ended up solving the problem:

This was the actual issue, clearly the body tag defined in CSS was not picked up.

My environment: Chrome Browser/Safari,

First time when it does not work, So according to the thread recommendation here I ended up adding the css file with the html entry

Sample CSS file: mystyle.css

<style type="”text/css”">
html {
 background-color:#000000;
 background-repeat:repeat-x;
 }

body {
 background-color: #DCDBD9;
color: #2C2C2C;
font: normal 100% Cambria, Georgia, serif;
}
</style>

Sample html file:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">

<html>
<head>
  <meta name="generator" content="HTML Tidy for Mac OS X (vers 31 October 2006 - Apple Inc. build 15.6), see www.w3.org">

  <title>Test Html File</title>
  <link rel="stylesheet" href="mystyle.css" type="text/css">
</head>

<body>
  <h1>Achieve sentence with Skynet! READ MORE</a></h1>
</body>
</html>

After the first loading it will work in Chrome and then go back to CSS file comment the html entry, so your modified CSS will be

<style type="”text/css”">
// html {
//    background-color:#000000;
//    background-image:url('bg.png');
//    background-repeat:repeat-x;
// }

body {
    background-color: #DCDBD9;
    color: #2C2C2C;
    font: normal 100% Cambria, Georgia, serif;
    }

  </style>

Clearly seems to be bug in webkit, Saw the same behavior in Safari as well. Thanks for sharing the html information, have been hunting around forever of why the body tag was not working.

The final output is something like this:

You can use the getTime() method on a Date object to get the timestamp (in milliseconds) relative to January 1, 1970. If you convert your two dates into integer timestamps, you can then compare the difference by subtracting them. The result will be in milliseconds so you just divide by 1000 for seconds, then 60 for minutes, etc.

You'll need to join twice:

SELECT home.*, away.*, g.network, g.date_start 
FROM game AS g
INNER JOIN team AS home
  ON home.importid = g.home
INNER JOIN team AS away
  ON away.importid = g.away
ORDER BY g.date_start DESC 
LIMIT 7

I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.

However, I fortunately came across the following:

Rahul's blog

which informs that servicemodelreg also needs to be run:

Run Visual Studio 2008 Command Prompt as “Administrator”. Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. Run this command servicemodelreg –i.

I suggest this discriminative question:

Is the open-source tool necessary in your process of making money?

• a blog engine on your commercial web site is necessary: commercial use.
• winamp for listening to music is not necessary: non-commercial use.

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

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

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

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

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

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

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

Edit:

    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

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

I am using functional component, in that I am using Flatlist with redux data. I am managing all the state with Redux store. Here is the solution to update the Flatlist data after the api call.

I was first doing like this:-

const DATA  = useSelector((state) => state.address.address);


<FlatList
    style = {styles.myAddressList}
    data = {DATA}
    renderItem = {renderItem}
    keyExtractor = {item => item._id}
    ListEmptyComponent = {EmptyList}
    ItemSeparatorComponent={SeparatorWhite}
    extraData = {refresh}
    
    />

but the data was not re-rendering my Flatlist data at all.

As a solution I did like given Below:-

<FlatList
    style = {styles.myAddressList}
    data = {useSelector((state) => state.address.address)}
    renderItem = {renderItem}
    keyExtractor = {item => item._id}
    ListEmptyComponent = {EmptyList}
    ItemSeparatorComponent={SeparatorWhite}
    />

I am passing the Redux state directly to the Flatlist Datasource rather than allocating it to the variable.

Thank you.

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:

public class Child : Parent 
{
    public void LoadData() 
    {
        base.MyMethod(); // call method of parent class
        base.CurrentRow = 1; // set property of parent class
        // other stuff...
    }
}

Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

If you don't need a signed integer, this is an alternative that uses a slightly different approach, is easy to read and doesn't require an import:

def distance(a, b):
  if a > 0 and b > 0:
    return max(a, b) - min(a, b)
  elif a < 0 and b < 0:
    return abs(a - b)
  elif a == b:
    return 0
  return abs(a - 0) + abs(b - 0)

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

for the 0 minutes text, added a float left to the first div, but personally i'd just combine them, although you may have reasons not to.

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".

You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server

and this is the function I'm using to write cross domain headers:

func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
    // Cross domain headers
    if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
        w.Header().Set("Access-Control-Allow-Headers", acrh[0])
    }
    w.Header().Set("Access-Control-Allow-Credentials", "True")
    if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
        w.Header().Set("Access-Control-Allow-Origin", acao[0])
    } else {
        if _, oko := req.Header["Origin"]; oko {
            w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
        } else {
            w.Header().Set("Access-Control-Allow-Origin", "*")
        }
    }
    w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
    w.Header().Set("Connection", "Close")

}

Use auto margins.

div {
   margin-left: auto;
   margin-right: auto;
   width: NNNpx;

   /* NOTE: Only works for non-floated block elements */
   display: block;
   float: none;
}

The kernel space means a memory space can only be touched by kernel. On 32bit linux it is 1G(from 0xC0000000 to 0xffffffff as virtual memory address).Every process created by kernel is also a kernel thread, So for one process, there are two stacks: one stack in user space for this process and another in kernel space for kernel thread.

the kernel stack occupied 2 pages(8k in 32bit linux), include a task_struct(about 1k) and the real stack(about 7k). The latter is used to store some auto variables or function call params or function address in kernel functions. Here is the code(Processor.h (linux\include\asm-i386)):

#define THREAD_SIZE (2*PAGE_SIZE)
#define alloc_task_struct() ((struct task_struct *) __get_free_pages(GFP_KERNEL,1))
#define free_task_struct(p) free_pages((unsigned long) (p), 1)

__get_free_pages(GFP_KERNEL,1)) means alloc memory as 2^1=2 pages.

But the process stack is another thing, its address is just bellow 0xC0000000(32bit linux), the size of it can be quite bigger, used for the user space function calls.

So here is a question come for system call, it is running in kernel space but was called by process in user space, how does it work? Will linux put its params and function address in kernel stack or process stack? Linux's solution: all system call are triggered by software interruption INT 0x80. Defined in entry.S (linux\arch\i386\kernel), here is some lines for example:

ENTRY(sys_call_table)
.long SYMBOL_NAME(sys_ni_syscall)   /* 0  -  old "setup()" system call*/
.long SYMBOL_NAME(sys_exit)
.long SYMBOL_NAME(sys_fork)
.long SYMBOL_NAME(sys_read)
.long SYMBOL_NAME(sys_write)
.long SYMBOL_NAME(sys_open)     /* 5 */
.long SYMBOL_NAME(sys_close)

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)

Consider changing your markup to this:

<span id="someId">onlineff</span>

Then you can use this script:

var x = document.getElementById('someId');
x.style.color = '#00FF00';

If you want to automate the creating of a custom divergent colormap commonly used for surface plots, this module combined with @unutbu method worked well for me.

def diverge_map(high=(0.565, 0.392, 0.173), low=(0.094, 0.310, 0.635)):
    '''
    low and high are colors that will be used for the two
    ends of the spectrum. they can be either color strings
    or rgb color tuples
    '''
    c = mcolors.ColorConverter().to_rgb
    if isinstance(low, basestring): low = c(low)
    if isinstance(high, basestring): high = c(high)
    return make_colormap([low, c('white'), 0.5, c('white'), high])

The high and low values can be either string color names or rgb tuples. This is the result using the surface plot demo:

For Perl one-liners with implicit loops (using -n or -p command line options), use last or last LINE to break out of the loop that iterates over input records. For example, these simple examples all print the first 2 lines of the input:

echo 1 2 3 4 | xargs -n1 | perl -ne 'last if $. == 3; print;'
echo 1 2 3 4 | xargs -n1 | perl -ne 'last LINE if $. == 3; print;'
echo 1 2 3 4 | xargs -n1 | perl -pe 'last if $. == 3;'
echo 1 2 3 4 | xargs -n1 | perl -pe 'last LINE if $. == 3;'

All print:

1
2

The perl one-liners use these command line flags:
-e : tells Perl to look for code in-line, instead of in a file.
-n : loop over the input one line at a time, assigning it to $_ by default.
-p : same as -n, also add print after each loop iteration over the input.

Ran into a similar issue, in that creating custom error messages for my custom exceptions make ugly code. This was my solution:

class MyRunTimeException: public std::runtime_error
{
public:
      MyRunTimeException(const std::string &filename):std::runtime_error(GetMessage(filename)) {}
private:
      static std::string GetMessage(const std::string &filename)
     {
           // Do your message formatting here. 
           // The benefit of returning std::string, is that the compiler will make sure the buffer is good for the length of the constructor call
           // You can use a local std::ostringstream here, and return os.str()
           // Without worrying that the memory is out of scope. It'll get copied
           // You also can create multiple GetMessage functions that take all sorts of objects and add multiple constructors for your exception
     }
}

This separates the logic for creating the messages. I had originally thought about overriding what(), but then you have to capture your message somewhere. std::runtime_error already has an internal buffer.

First off, using the mail() function that comes with PHP is not an optimal solution. It is easily marked as spammed, and you need to set up header to ensure that you are sending HTML emails correctly. As for whether the code snippet will work, it would, but I doubt you will get HTML code inside it correctly without specifying extra headers

I'll suggest you take a look at SwiftMailer, which has HTML support, support for different mime types and SMTP authentication (which is less likely to mark your mail as spam).

git fetch upstream --tags

works just fine, it will only get new tags and will not get any other code base.

Overload less than operator, then sort. This is an example I found off the web...

class MyData
{
public:
  int m_iData;
  string m_strSomeOtherData;
  bool operator<(const MyData &rhs) const { return m_iData < rhs.m_iData; }
};

std::sort(myvector.begin(), myvector.end());

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

if you need a lighter solution i recommend mysql-shell, install using the command below.

brew cask install mysql-shell

To start after installation type mysqlsh.

The prototype-solution from Krishna Chytanya is very nice, but needs a minor but important improvement. The days param must be parsed as Integer to avoid weird calculations when days is a String like "1". (I needed several hours to find out, what went wrong in my application.)

Date.prototype.addDays = function(days) {
    this.setDate(this.getDate() + parseInt(days));
    return this;
};

Even if you do not use this prototype function: Always be sure to have an Integer when using setDate().

This should be a one-liner:

public static class ProcessHelpers {

< is for one-way binding.

@ binding is for passing strings. These strings support {{}} expressions for interpolated values.

= binding is for two-way model binding. The model in parent scope is linked to the model in the directive's isolated scope.

& binding is for passing a method into your directive's scope so that it can be called within your directive.

When we are setting scope: true in directive, Angular js will create a new scope for that directive. That means any changes made to the directive scope will not reflect back in parent controller.

You can try inserting it in sys.path:

sys.path.insert(0, './lib')
import BoxTime

If you are using SQL Server 2005 (or greater) you might want to consider switching to NVARCHAR(MAX) in your table definition; TEXT, NTEXT, and IMAGE data types of SQL Server 2000 will be deprecated in future versions of SQL Server. SQL Server 2005 provides backward compatibility to data types, but you should probably be using VARCHAR(MAX), NVARCHAR(MAX), and VARBINARY(MAX) instead.

You can use something like this:

List<Object[]> list = em.createQuery("SELECT p.field1, p.field2 FROM Entity p").getResultList();

then you can iterate over it:

for (Object[] obj : list){
    System.out.println(obj[0]);
    System.out.println(obj[1]);
}

BUT if you have only one field in query, you get a list of the type not from Object[]

only the below code in Python 3.7 worked for me

from datetime import datetime,timedelta    
print(datetime.now()-timedelta(seconds=900))

The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.

If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

The HOME button cannot be intercepted by applications. This is a by-design behavior in Android. The reason is to prevent malicious apps from gaining control over your phone (If the user cannot press back or home, he might never be able to exit the app). The Home button is considered the user's "safe zone" and will always launch the user's configured home app.

The only exception to the above is any app configured as home replacement. Which means it has the following declared in its AndroidManifest.xml for the relevant activity:

<intent-filter>
   <action android:name="android.intent.action.MAIN" />
   <category android:name="android.intent.category.HOME" />
   <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

When pressing the home button, the current home app's activity's onNewIntent will be called.

If you want to keep the row with the lowest id value:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MIN(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

If you want the id value that is the highest:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MAX(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

The subquery in a subquery is necessary for MySQL, or you'll get a 1093 error.

I dont know if you can select a specific number of columns?

I shared my experience of using two LEFT JOINS in a single SQL query.

I have 3 tables:

Table 1) Patient consists columns PatientID, PatientName

Table 2) Appointment consists columns AppointmentID, AppointmentDateTime, PatientID, DoctorID

Table 3) Doctor consists columns DoctorID, DoctorName

Query:

SELECT Patient.patientname, AppointmentDateTime, Doctor.doctorname

FROM Appointment 

LEFT JOIN Doctor ON Appointment.doctorid = Doctor.doctorId  //have doctorId column common

LEFT JOIN Patient ON Appointment.PatientId = Patient.PatientId      //have patientid column common

WHERE Doctor.Doctorname LIKE 'varun%' // setting doctor name by using LIKE

AND Appointment.AppointmentDateTime BETWEEN '1/16/2001' AND '9/9/2014' //comparison b/w dates 

ORDER BY AppointmentDateTime ASC;  // getting data as ascending order

I wrote the solution to get date format like "mm/dd/yy" (under my name "VARUN TEJ REDDY")

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

For me, this is the best autofit and autoresize for table and its columns (use css !important ... only if you can't without)

.myclass table {
    table-layout: auto !important;
}

.myclass th, .myclass td, .myclass thead th, .myclass tbody td, .myclass tfoot td, .myclass tfoot th {
    width: auto !important;
}

Don't specify css width for table or for table columns. If table content is larger it will go over screen size to.

The corrected code is

import urllib.request
fhand = urllib.request.urlopen('http://data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand: 
    words = line.decode().split() 
for word in words: 
    counts[word] = counts.get(word, 0) + 1 
print(counts) 

running the code above produces

{'Who': 1, 'is': 1, 'already': 1, 'sick': 1, 'and': 1, 'pale': 1, 'with': 1, 'grief': 1}

In my search for a creating a v4 uuid, I came first to this page, then found this on http://php.net/manual/en/function.com-create-guid.php

function guidv4()
{
    if (function_exists('com_create_guid') === true)
        return trim(com_create_guid(), '{}');

    $data = openssl_random_pseudo_bytes(16);
    $data[6] = chr(ord($data[6]) & 0x0f | 0x40); // set version to 0100
    $data[8] = chr(ord($data[8]) & 0x3f | 0x80); // set bits 6-7 to 10
    return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}

Edit: to clarify, this function will always give you a v4 uuid (PHP >= 5.3.0).

When the com_create_guid function is available (usually only on Windows), it will use that and strip the curly braces.

If not present (Linux), it will fall back on this strong random openssl_random_pseudo_bytes function, it will then uses vsprintf to format it into v4 uuid.

1. give the read / write permission to the IIS user or group users

2. Start -> run -> inetmgr

   enable the ASP.NET authentication for your default website

3. For 64-bit (x64), create this folder: C:\Windows\SysWOW64\config\systemprofile\Desktop

For 32-bit (x86), create this folder: C:\Windows\System32\config\systemprofile\Desktop

The windows service, if running under the systemprofile, needs the Desktop folder. This folder was automatically created on XP and older Windows Server versions, but not for Vista and Windows 2008 Server.

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

this code will display loading on the button label, and set button to

                        $(this).text($(this).attr("label"));
                    })
                });
                //processing finalized
            });
        });
    });
    // and fire it after definition
});

You simply need to use semilogy instead of plot:

from pylab import *
import matplotlib.pyplot  as pyplot
a = [ pow(10,i) for i in range(10) ]
fig = pyplot.figure()
ax = fig.add_subplot(2,1,1)

line, = ax.semilogy(a, color='blue', lw=2)
show()

The first part of your question can be solved with just HTML & CSS; you'll need to use Javascript for the second part.

Getting the Label Near the Radio Button

I'm not sure what you mean by "next to": on the same line and near, or on separate lines? If you want all of the radio buttons on the same line, just use margins to push them apart. If you want each of them on their own line, you have two options (unless you want to venture into float: territory):

• Use <br />s to split the options apart and some CSS to vertically align them:

<style type='text/css'>
    .input input
    {
        width: 20px;
    }
</style>
<div class="input radio">
    <fieldset>
        <legend>What color is the sky?</legend>
        <input type="hidden" name="data[Submit][question]" value="" id="SubmitQuestion" />

        <input type="radio" name="data[Submit][question]" id="SubmitQuestion1" value="1"  />
        <label for="SubmitQuestion1">A strange radient green.</label>
        <br />
        <input type="radio" name="data[Submit][question]" id="SubmitQuestion2" value="2"  />
        <label for="SubmitQuestion2">A dark gloomy orange</label>
        <br />
        <input type="radio" name="data[Submit][question]" id="SubmitQuestion3" value="3"  />
        <label for="SubmitQuestion3">A perfect glittering blue</label>
    </fieldset>
</div>

• Follow A List Apart's article: Prettier Accessible Forms

Applying a Style to the Currently Selected Label + Radio Button

Styling the <label> is why you'll need to resort to Javascript. A library like jQuery is perfect for this:

<style type='text/css'>
    .input label.focused
    {
        background-color: #EEEEEE;
        font-style: italic;
    }
</style>
<script type='text/javascript' src='jquery.js'></script>
<script type='text/javascript'>
    $(document).ready(function() {
        $('.input :radio').focus(updateSelectedStyle);
        $('.input :radio').blur(updateSelectedStyle);
        $('.input :radio').change(updateSelectedStyle);
    })

    function updateSelectedStyle() {
        $('.input :radio').removeClass('focused').next().removeClass('focused');
        $('.input :radio:checked').addClass('focused').next().addClass('focused');
    }
</script>

The focus and blur hooks are needed to make this work in IE.

Step 1: Download any JAR file for your Project.

Step 2: Copy .jar file and past in libs folder.

You can get the total count of lines with wc -l <file> and use

head -n <total lines - lines to remove> <file>

Iterate through a copy of the list and add new elements to the original list.

for (String s : new ArrayList<String>(list))     
{
    list.add("u");
}

    public Multipart (String url, Map<String, String> headers) {
        this.url = url;

        }
        con.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        con.connect();
        os = con.getOutputStream();

        os.write(("Content-Disposition: form-data; name=\"" + paramName + "\"; filename=\"" + fileName + "\"\r\n").getBytes());
        os.write(("Content-Type: application/octet-stream\r\n").getBytes());
        os.write(("Content-Transfer-Encoding: binary\r\n").getBytes());
        os.write("\r\n".getBytes());

        os.write(data);

        os.write("\r\n".getBytes());
    }

    public void finishMultipart() throws Exception {
        os.write((delimiter + boundary + delimiter + "\r\n").getBytes());
    }


    public String getResponse() throws Exception {
        InputStream is = con.getInputStream();
        byte[] b1 = new byte[1024];
        StringBuffer buffer = new StringBuffer();

        while (is.read(b1) != -1)
            buffer.append(new String(b1));

        con.disconnect();

        return buffer.toString();
    }


    private void writeParamData(String paramName, String value) throws Exception {


        os.write((delimiter + boundary + "\r\n").getBytes());
        os.write("Content-Type: text/plain\r\n".getBytes());//;charset=utf-8
        os.write(("Content-Disposition: form-data; name=\"" + paramName + "\"\r\n").getBytes());
        ;
        os.write(("\r\n" + value + "\r\n").getBytes());


    }
}

Then call below

Multipart multipart = new Multipart(url__, map);
            multipart .connectForMultipart();
multipart .addFormPart(entry.getKey(), entry.getValue());
multipart .addFilePart(KeyName, "FileName", imagedata);
multipart .finishMultipart();

If none of the answers work for you which happened to me on macbook pro in one of the projects you can always try to run Android Studio with an alias command passing sdk.dir with each run:

alias studio='launchctl setenv ANDROID_HOME '\''/Users/username/Library/Android/sdk'\'' && open -a '\''Android Studio'\'''

The Kotlin approach

inline fun <reified T: Class<R.drawable>> T.getId(resourceName: String): Int {
            return try {
                val idField = getDeclaredField (resourceName)
                idField.getInt(idField)
            } catch (e:Exception) {
                e.printStackTrace()
                -1
            }
        }

Usage:

val resId = R.drawable::class.java.getId("icon")

In Debian NGINX environment i did the following.

Goto /etc/mysql/mysql.conf.d edit mysqld.cnf if you find log-error = /var/log/mysql/error.log add the following 2 lines bellow it.

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

To see the logs goto /var/log/mysql and tail -f mysql.log

Remember to comment these lines out once you are done with debugging if you are in production environment delete mysql.log as this log file will grow quickly and can be huge.

If you're using local workspaces (TFS 2012+) you can now use the .tfignore file to exclude local folders and files from being checked in.

If you add that file to source control you can ensure others on your team share the same exclusion settings.

Full details on MSDN - http://msdn.microsoft.com/en-us/library/ms245454.aspx#tfignore

For the lazy:

You can configure which kinds of files are ignored by placing a text file called .tfignore in the folder where you want rules to apply. The effects of the .tfignore file are recursive. However, you can create .tfignore files in sub-folders to override the effects of a .tfignore file in a parent folder.

The following rules apply to a .tfignore file:

• # begins a comment line
• The * and ? wildcards are supported.
• A filespec is recursive unless prefixed by the \ character.
• ! negates a filespec (files that match the pattern are not ignored)

Example file:

# Ignore .cpp files in the ProjA sub-folder and all its subfolders
ProjA\*.cpp
# 
# Ignore .txt files in this folder 
\*.txt
#
# Ignore .xml files in this folder and all its sub-folders
*.xml
#
# Ignore all files in the Temp sub-folder
\Temp
#
# Do not ignore .dll files in this folder nor in any of its sub-folders
!*.dll

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

The long values, most likely, correspond to Epoch timestamps, and the values are:

1220227200 = Mon, 01 Sep 2008 00:00:00 GMT

1220832000 = Mon, 08 Sep 2008 00:00:00 GMT

1221436800 = Mon, 15 Sep 2008 00:00:00 GMT

One can convert these long values to java.util.Date, taking into account the fact java.util.Date uses millisecs – as previously hinted, but with some flaw - like this:

// note: enforcing long literals (L), without it the values would just be wrong.
Date date = new Date(1220227200L * 1000L); 

Now, to display the date correctly, one can use java.text.DateFormat as illustrated hereafter:

DateFormat df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println("Wrong date time value: " + date);
System.out.println("Correct date time value: " + df.format(date));

Below are the results of displaying the converted long value to java.util.Date without using and using the DateFormat:

Date wrong (off by 2 hours): Mon Sep 01 02:00:00 CEST 2008
Correct date : Monday, 1 September 2008 00:00:00 o'clock UTC

import sys
sys.executable

will give you the interpreter. You can select the interpreter you want when you create a new notebook. Make sure the path to your anaconda interpreter is added to your path (somewhere in your bashrc/bash_profile most likely).

For example I used to have the following line in my .bash_profile, that I added manually :

export PATH="$HOME/anaconda3/bin:$PATH"

EDIT: As mentioned in a comment, this is not the proper way to add anaconda to the path. Quoting Anaconda's doc, this should be done instead after install, using conda init:

Should I add Anaconda to the macOS or Linux PATH?

We do not recommend adding Anaconda to the PATH manually. During installation, you will be asked “Do you wish the installer to initialize Anaconda3 by running conda init?” We recommend “yes”. If you enter “no”, then conda will not modify your shell scripts at all. In order to initialize after the installation process is done, first run source <path to conda>/bin/activate and then run conda init

How about a Bash Here Document:

ssh otherhost << EOF
  ls some_folder; 
  ./someaction.sh 'some params'
  pwd
  ./some_other_action 'other params'
EOF

To avoid the problems mentioned by @Globalz in the comments, you may be able to (depending what you're doing on the remote site) get away with replacing the first line with

ssh otherhost /bin/bash << EOF

Note that you can do variable substitution in the Here document, but you may have to deal with quoting issues. For instance, if you quote the "limit string" (ie. EOF in the above), then you can't do variable substitutions. But without quoting the limit string, variables are substituted. For example, if you have defined $NAME above in your shell script, you could do

ssh otherhost /bin/bash << EOF
touch "/tmp/${NAME}"
EOF

and it would create a file on the destination otherhost with the name of whatever you'd assigned to $NAME. Other rules about shell script quoting also apply, but are too complicated to go into here.

The Character class of Java API has various functions you can use.

You can convert your char to lowercase at both sides:

Character.toLowerCase(name1.charAt(i)) == Character.toLowerCase(name2.charAt(j))

There are also a methods you can use to verify if the letter is uppercase or lowercase:

Character.isUpperCase('P')
Character.isLowerCase('P') 

Instructions:

1. Click on the Terminal icon in the desktop panel to open a terminal window and access the command prompt.
2. Type the command which java to find the path to the Java executable file.
3. Type the command su - to become the root user.
4. Type the command vi /root/.bash_profile to open the system bash_profile file in the Vi text editor. You can replace vi with your preferred text editor.
5. Type export JAVA_HOME=/usr/local/java/ at the bottom of the file. Replace /usr/local/java with the location found in step two.
6. Save and close the bash_profile file.
7. Type the command exit to close the root session.
8. Log out of the system and log back in.
9. Type the command echo $JAVA_HOME to ensure that the path was set correctly.

set java_home in centos

You can do the following:

echo '<div class="my_class">';
echo ($cart->count_product > 0) ? $cart->count_product : '';
echo '</div>';

If you want to have it inside your statement, do this:

if($cart->count_product > 0) 
{
    echo '<div class="my_class">'.$cart->count_product.'</div>';
}

You don't need the else statement, since you're only going to output the above when it's truthy anyway.

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

You can emulate any other data structure with a hashmap, so that's not a terrible limitation. Scanning from the top to the bottom, you create a hashmap for each row of the database, with an entry for each column. Add each of these hashmaps to a "master" hashmap, keyed on the id. If any node has a "parent" that you haven't seen yet, create an placeholder entry for it in the master hashmap, and fill it in when you see the actual node.

To print it out, do a simple depth-first pass through the data, keeping track of indent level along the way. You can make this easier by keeping a "children" entry for each row, and populating it as you scan the data.

As for whether there's a "better" way to store a tree in a database, that depends on how you're going to use the data. I've seen systems that had a known maximum depth that used a different table for each level in the hierarchy. That makes a lot of sense if the levels in the tree aren't quite equivalent after all (top level categories being different than the leaves).

You will have to connect your RDS through a computer which as mysql installed on it I used one of my hosting VPS using SSH

After i was logged in my VPS ( i used putty ) It was simple, in the prompt i entered the following command:

mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts

There is no option to downgrade XAMPP. XAMPP is hardcoded with specific PHP version to make sure all the modules are compatible and working properly. However if your project needs PHP 5.6, you can just install a older version of XAMPP with PHP 5.6 packaged into it.

Source: How to downgrade php from 5.5 to 5.3

It could be not a problem with a single line of your code.

On some devices (I don't recall if it is in stock Android) the Permission dialog includes a check box labeled "Never ask again". If you click Deny with the box checked then you won't be prompted again for that permission, it will automatically be denied to the app. To revert this, you have to go into Settings -> App -> Permissions and re--enable that perm for the app. Then turn it off to deny it again. You may have to open the app before turning it off again, not sure.

I don't know if your Nexus has it. Maybe worth a try.

The syntax error is just due to a missing alias for the subquery:

from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5)  mySubQuery  /* Alias */

java.io.File class contains four static separator variables. For better understanding, Let's understand with the help of some code

1. separator: Platform dependent default name-separator character as String. For windows, it’s ‘\’ and for unix it’s ‘/’
2. separatorChar: Same as separator but it’s char
3. pathSeparator: Platform dependent variable for path-separator. For example PATH or CLASSPATH variable list of paths separated by ‘:’ in Unix systems and ‘;’ in Windows system
4. pathSeparatorChar: Same as pathSeparator but it’s char

Note that all of these are final variables and system dependent.

Here is the java program to print these separator variables. FileSeparator.java

import java.io.File;

public class FileSeparator {

    public static void main(String[] args) {
        System.out.println("File.separator = "+File.separator);
        System.out.println("File.separatorChar = "+File.separatorChar);
        System.out.println("File.pathSeparator = "+File.pathSeparator);
        System.out.println("File.pathSeparatorChar = "+File.pathSeparatorChar);
    }

}

Output of above program on Unix system:

File.separator = /
File.separatorChar = /
File.pathSeparator = :
File.pathSeparatorChar = :

Output of the program on Windows system:

File.separator = \
File.separatorChar = \
File.pathSeparator = ;
File.pathSeparatorChar = ;

To make our program platform independent, we should always use these separators to create file path or read any system variables like PATH, CLASSPATH.

Here is the code snippet showing how to use separators correctly.

//no platform independence, good for Unix systems
File fileUnsafe = new File("tmp/abc.txt");
//platform independent and safe to use across Unix and Windows
File fileSafe = new File("tmp"+File.separator+"abc.txt");

look at the example

window.history.replaceState({
    foo: 'bar'
}, 'Nice URL Title', '/nice_url');

window.onpopstate = function (e) {
    if (typeof e.state == "object" && e.state.foo == "bar") {
        alert("Blah blah blah");
    }
};

window.history.go(-1);

and search location.hash;

Use dictionary comprehension way,

x = {k:v for k,v in enumerate(states) if v == True}

Input:

states = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]

Output:

{4: True, 5: True, 7: True}

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

Using REGEX you can remove the spaces in a string.

The following namespace is mandatory.

using System.Text.RegularExpressions;

Syntax:

Regex.Replace(text, @"\s", "")

This is possible! At least now that css transforms have good support:

You need to use a CSS transform to scale the image - the trick is not just to use a scale(), but also to apply a very small rotation. This triggers IE to use a smoother interpolation of the image:

img {
    /* double desired size */
    width: 56px; 
    height: 56px;

    /* margins to reduce layout size to match the transformed size */ 
    margin: -14px -14px -14px -14px; 

    /* transform to scale with smooth interpolation: */
    transform: scale(0.5) rotate(0.1deg);
}

Even though @JamesMcNellis answer is a valid one I would like to explain something about error handling and also the fact that there is another way of doing what you want.

You have four ways of accessing a specific item in a vector:

• Using the [] operator
• Using the member function at(...)
• Using an iterator in combination with a given offset
• Using std::for_each from the algorithm header of the standard C++ library. This is another way which I can recommend (it uses internally an iterator). You can read more about it for example here.

In the following examples I will be using the following vector as a lab rat and explaining the first three methods:

static const int arr[] = {1, 2, 3, 4};
std::vector<int> v(arr, arr+sizeof(arr)/sizeof(arr[0]));

This creates a vector as seen below:

1 2 3 4

First let's look at the [] way of doing things. It works in pretty much the same way as you expect when working with a normal array. You give an index and possibly you access the item you want. I say possibly because the [] operator doesn't check whether the vector actually has that many items. This leads to a silent invalid memory access. Example:

v[10] = 9;

This may or may not lead to an instant crash. Worst case is of course is if it doesn't and you actually get what seems to be a valid value. Similar to arrays this may lead to wasted time in trying to find the reason why for example 1000 lines of code later you get a value of 100 instead of 234, which is somewhat connected to that very location where you retrieve an item from you vector.

A much better way is to use at(...). This will automatically check for out of bounds behaviour and break throwing an std::out_of_range. So in the case when we have

v.at(10) = 9;

We will get:

terminate called after throwing an instance of 'std::out_of_range'
what(): vector::_M_range_check: __n (which is 10) >= this->size() (which is 4)

The third way is similar to the [] operator in the sense you can screw things up. A vector just like an array is a sequence of continuous memory blocks containing data of the same type. This means that you can use your starting address by assigning it to an iterator and then just add an offset to this iterator. The offset simply stands for how many items after the first item you want to traverse:

std::vector<int>::iterator it = v.begin(); // First element of your vector
*(it+0) = 9;  // offest = 0 basically means accessing v.begin()
// Now we have 9 2 3 4 instead of 1 2 3 4
*(it+1) = -1; // offset = 1 means first item of v plus an additional one
// Now we have 9 -1 3 4 instead of 9 2 3 4
// ...

As you can see we can also do

*(it+10) = 9;

which is again an invalid memory access. This is basically the same as using at(0 + offset) but without the out of bounds error checking.

I would advice using at(...) whenever possible not only because it's more readable compared to the iterator access but because of the error checking for invalid index that I have mentioned above for both the iterator with offset combination and the [] operator.

Try this:

tar -zxvf file.tar.gz

    $('body').append($('<div/>', {
        id: 'holdy' 
    }));

You can use the asXML method

echo $xml->asXML();

You can also give it a filename

$xml->asXML('filename.xml');

I was experiencing the same problem and the problem was that I hade several projects in the solution (Weband Droid) and even though Default project was choosen in the Package Manager Console it used the connection string from the Droid project:

PM> update-database -Verbose
Using StartUp project 'Droid'. <-- DROID
Using NuGet project 'Web'. <-- WEB
Specify the '-Verbose' flag to view the SQL statements being applied to the target database.
<!-- BAD TARGET DATABASE -->
Target database is: 'DefaultConnection' (DataSource: .\SQLEXPRESS, Provider: System.Data.SqlClient, Origin: Convention).
System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

After setting the Startup Project to Web and the Default Project in Package Manger Console I got it to work.

//photo is bitmap image

Bitmap btm00 = Utils.getResizedBitmap(photo, 200, 200);

 setimage.setImageBitmap(btm00);

  And in Utils class :

public static Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);
    // RECREATE THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height,
            matrix, false);
    return resizedBitmap;
}

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

EXP (export) and IMP (import) are the two tools you need. It's is better to try to run these on the command line and on the same machine.

It can be run from remote, you just need to setup you TNSNAMES.ORA correctly and install all the developer tools with the same version as the database. Without knowing the error message you are experiencing then I can't help you to get exp/imp to work.

The command to export a single user:

exp userid=dba/dbapassword OWNER=username DIRECT=Y FILE=filename.dmp

This will create the export dump file.

To import the dump file into a different user schema, first create the newuser in SQLPLUS:

SQL> create user newuser identified by 'password' quota unlimited users;

Then import the data:

imp userid=dba/dbapassword FILE=filename.dmp FROMUSER=username TOUSER=newusername

If there is a lot of data then investigate increasing the BUFFERS or look into expdp/impdp

Most common errors for exp and imp are setup. Check your PATH includes $ORACLE_HOME/bin, check $ORACLE_HOME is set correctly and check $ORACLE_SID is set

I agree httpclient is something of a standard - but I guess you are looking for options so...

Restlet provides a http client specially designed for interactong with Restful web services.

Example code:

    Client client = new Client(Protocol.HTTP);
    Request r = new Request();
    r.setResourceRef("http://127.0.0.1:8182/sample");
    r.setMethod(Method.GET);
    r.getClientInfo().getAcceptedMediaTypes().add(new Preference<MediaType>(MediaType.TEXT_XML));
    client.handle(r).getEntity().write(System.out);

See http://www.restlet.org/ for more details

Using Maven

First of all you should install android libraries to your local maven repository using Maven Android SDK Deployer

Then you can add dependency to your pom like this:

    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v7-appcompat</artifactId>
        <version>${compatibility.version}</version>
        <type>apklib</type>
    </dependency>

    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v7-appcompat</artifactId>
        <version>${compatibility.version}</version>
        <type>jar</type>
    </dependency>

You could put \s* inbetween every character in your search string so if you were looking for cat you would use c\s*a\s*t\s*s\s*s

It's long but you could build the string dynamically of course.

You can see it working here: http://www.rubular.com/r/zzWwvppSpE

Working Demo here>

The request body is available as byte stream by HttpServletRequest#getInputStream():

InputStream body = request.getInputStream();
// ...

Or as character stream by HttpServletRequest#getReader():

Reader body = request.getReader();
// ...

Note that you can read it only once. The client ain't going to resend the same request multiple times. Calling getParameter() and so on will implicitly also read it. If you need to break down parameters later on, you've got to store the body somewhere and process yourself.

Probably the best way is to use Guava

List<String> list = new ArrayList<String>();
list.add("How are you");
list.add("How you doing");
list.add("Joe");
list.add("Mike");
    
Collection<String> filtered = Collections2.filter(list,
    Predicates.containsPattern("How"));
print(filtered);

prints

How are you
How you doing

In case you want to get the filtered collection as a list, you can use this (also from Guava):

List<String> filteredList = Lists.newArrayList(Collections2.filter(
    list, Predicates.containsPattern("How")));

A real working solution with no other dependencies than angularjs (tested with v.1.0.6)

html

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>

Angularjs (1.0.6) not support ng-model on "input-file" tags so you have to do it in a "native-way" that pass the all (eventually) selected files from the user.

controller

$scope.uploadFile = function(files) {
    var fd = new FormData();
    //Take the first selected file
    fd.append("file", files[0]);

    $http.post(uploadUrl, fd, {
        withCredentials: true,
        headers: {'Content-Type': undefined },
        transformRequest: angular.identity
    }).success( ...all right!... ).error( ..damn!... );

};

The cool part is the undefined content-type and the transformRequest: angular.identity that give at the $http the ability to choose the right "content-type" and manage the boundary needed when handling multipart data.

I am currently on OS X 10.9 and my efforts to compile vim with +xterm_clipboard brought me nothing. So my current solution is to use MacVim in terminal mode with option set clipboard=unnamed in my ~/.vimrc file. Works perfect for me.

It's always better to use the iterator instead of indexing. This is because iterator is most likely optimzied for the List implementation while indexed (calling get) might not be. For example LinkedList is a List but indexing through its elements will be slower than iterating using the iterator.

In python 3.4, while in a virtual environment, make sure you have the build dependencies first:

sudo apt-get build-dep python3-psycopg2

Then install it:

pip install psycopg2 

I have no serial device here to test it, but if you have python and dbus you can try it yourself.

import dbus
bus = dbus.SystemBus()
hwmanager = bus.get_object('org.freedesktop.Hal', '/org/freedesktop/Hal/Manager')
hwmanager_i = dbus.Interface(hwmanager, 'org.freedesktop.Hal.Manager')
print hwmanager_i.FindDeviceByCapability("serial")

If it fails you can search inside hwmanager_i.GetAllDevicesWithProperties() to see if the capability name "serial" that I just guessed has a different name.
