EDIT: I wrote this answer up in haste, before realizing that your question is about sending values to a chan inside a goroutine. The approach below can be used either with an additional chan as suggested above, or using the fact that the chan you have already is bi-directional, you can use just the one...

If your goroutine exists solely to process the items coming out of the chan, you can make use of the "close" builtin and the special receive form for channels.

That is, once you're done sending items on the chan, you close it. Then inside your goroutine you get an extra parameter to the receive operator that shows whether the channel has been closed.

Here is a complete example (the waitgroup is used to make sure that the process continues until the goroutine completes):

package main

import "sync"
func main() {
    var wg sync.WaitGroup
    wg.Add(1)

    ch := make(chan int)
    go func() {
        for {
            foo, ok := <- ch
            if !ok {
                println("done")
                wg.Done()
                return
            }
            println(foo)
        }
    }()
    ch <- 1
    ch <- 2
    ch <- 3
    close(ch)

    wg.Wait()
}

I have this version about datetimepicker https://tempusdominus.github.io/bootstrap-4/ and for any reason doesn`t work the change event with jquery but with JS vanilla it does

I figure out like this

document.getElementById('date').onchange = function(){ ...the jquery code...}

I hope work for you

function Numbers(e)
{
    if($.browser.msie)
    {
        if(e.keyCode > 47 && e.keyCode < 58)
            return true;
        else
            return false;
    }
    else
    {
        if((e.charCode > 47 && e.charCode < 58) || (e.charCode == 0))
            return true;
        else
            return false;
    }
}

I hope this will work on all browsers.

In vb.net you can actually compare strings with =. Even though String is a reference type, in vb.net = on String has been redefined to do a case-sensitive comparison of contents of the two strings.

You can test this with the following code. Note that I have taken one of the values from user input to ensure that the compiler cannot use the same reference for the two variables like the Java compiler would if variables were defined from the same string Literal. Run the program, type "This" and press <Enter>.

Sub Main()
    Dim a As String = New String("This")
    Dim b As String

    b = Console.ReadLine()

    If a = b Then
        Console.WriteLine("They are equal")
    Else
        Console.WriteLine("Not equal")
    End If
    Console.ReadLine()
End Sub

It depends why the something is on the same line in the first place.

clear in the case of floats, display: block in the case of inline content naturally flowing, nothing will defeat position: absolute as the previous element will be taken out of the normal flow by it.

<table style='border:1px solid black'>
    <tr>
        <td>Derp</td>
    </tr>
</table>

This should work. I use the shorthand syntax for borders.

Scott Guthrie has made a post on how to change Visual Studio's default browser:

1) Right click on a .aspx page in your solution explorer

2) Select the "browse with" context menu option

3) In the dialog you can select or add a browser. If you want Firefox in the list, click "add" and point to the firefox.exe filename

4) Click the "Set as Default" button to make this the default browser when you run any page on the site.

I however dislike the fact that this isn't as straightforward as it should be.

I'm using Android Studio (JetBrains IntelliJ IDEA) on Mac OS and my problem was that ^M started to show up in some files in my pull request on GitHub. What worked for me was changing line separator for a file.

Open the desired file in the editor go to File go to Line Separators then choose the best option for you (for me it was LF - Unix and OS X(\n) )

According to the next article this problem is a result of confused line endings between operating systems: http://jonathonstaff.com/blog/issues-with-line-endings/

And more information you can find here: https://www.jetbrains.com/help/idea/configuring-line-separators.html#d84378e48

You need to add a Serializable attribute to the class which you want to serialize.

The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?

It's cleaner/safer to use the getters provided by google instead of accessing the properties like some did

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(polygon) {
    var coordinatesArray = polygon.overlay.getPath().getArray();
});

If:

• you want multiple, but not all, worksheets, and
• you want a single df as an output

Then, you can pass a list of worksheet names. Which you could populate manually:

import pandas as pd
    
path = "C:\\Path\\To\\Your\\Data\\"
file = "data.xlsx"
sheet_lst_wanted = ["01_SomeName","05_SomeName","12_SomeName"] # tab names from Excel

### import and compile data ###
    
# read all sheets from list into an ordered dictionary    
dict_temp = pd.read_excel(path+file, sheet_name= sheet_lst_wanted)

# concatenate the ordered dict items into a dataframe
df = pd.concat(dict_temp, axis=0, ignore_index=True)

OR

A bit of automation is possible if your desired worksheets have a common naming convention that also allows you to differentiate from unwanted sheets:

# substitute following block for the sheet_lst_wanted line in above block

import xlrd

# string common to only worksheets you want
str_like = "SomeName" 
    
### create list of sheet names in Excel file ###
xls = xlrd.open_workbook(path+file, on_demand=True)
sheet_lst = xls.sheet_names()
    
### create list of sheets meeting criteria  ###
sheet_lst_wanted = []
    
for s in sheet_lst:
    # note: following conditional statement based on my sheets ending with the string defined in sheet_like
    if s[-len(str_like):] == str_like:
        sheet_lst_wanted.append(s)
    else:
        pass

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

I can't comment, so I will put this as a separate answer. I found a few issues with the accepted one-liner answer:

• The one-liner includes a passphrase in the key.
• The one-liner uses SHA-1 which in many browsers throws warnings in console.

Here is a simplified version that removes the passphrase, ups the security to suppress warnings and includes a suggestion in comments to pass in -subj to remove the full question list:

openssl genrsa -out server.key 2048
openssl rsa -in server.key -out server.key
openssl req -sha256 -new -key server.key -out server.csr -subj '/CN=localhost'
openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

Replace 'localhost' with whatever domain you require. You will need to run the first two commands one by one as OpenSSL will prompt for a passphrase.

To combine the two into a .pem file:

cat server.crt server.key > cert.pem

You can use this code to retrieve values from multiple select combo box

HTML:

<form action="c3.php" method="post">
  <select name="ary[]" multiple="multiple">
    <option value="Option 1" >Option 1</option>
    <option value="Option 2">Option 2</option>
    <option value="Option 3">Option 3</option>
    <option value="Option 4">Option 4</option>
    <option value="Option 5">Option 5</option>
  </select>
  <input type="submit">
</form>

PHP:

<?php
$values = $_POST['ary'];

foreach ($values as $a){
    echo $a;
}
?>

Arrays are objects and they have a length field.

String[] haha = {"olle", "bulle"};

haha.length would be 2

That is so basic that I am wondering what book you are using to study? Try

data[1, "V1"]  # row first, quoted column name second, and case does matter

Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.

I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html

Use the jQuery hashchange event plugin instead. Regarding your full ajax navigation, try to have SEO friendly ajax. Otherwise your pages shown nothing in browsers with JavaScript limitations.

Separate the business rules for age from the actions e.g. (NB just typed, not checked)

enum eAgerange { eChild, eYouth, eAdult, eAncient};
eAgeRange ar;
if(age <= 8) ar = eChild;
else if(age <= 15) ar = eYouth;
else if(age <= 100) ar = eAdult;
else ar = eAncient;
switch(ar)
{
 case eChild: 
     // action
 case eYouth:
     // action
 case eAdult:
     // action
 case eAncient:
     // action
 default: throw new NotImplementedException($"Oops {ar.ToString()} not handled");
}

The virtual mechanism only works when you have a based class pointer to a derived class object. Construction has it's own rules for the calling of base class constructors, basically base class to derived. How could a virtual constructor be useful or called? I don't know what other languages do, but I can't see how a virtual constructor could be useful or even implemented. Construction needs to have taken place for the virtual mechanism to make any sense and construction also needs to have taken place for the vtable structures to have been created which provides the mechanics of the polymorphic behaviour.

<a href="<?php echo $_SERVER['DOCUMENT_ROOT'].'/hello.html'; ?>">go with php</a>
    <br />
<a href="/hello.html">go to with html</a>

Try this yourself and find that they are not exactly the same.

$_SERVER['DOCUMENT_ROOT'] renders an actual file path (on my computer running as it's own server, C:/wamp/www/

HTML's / renders the root of the server url, in my case, localhost/

But C:/wamp/www/hello.html and localhost/hello.html are in fact the same file

You can also pull the latest commit and just undo until the commit you desire:

git pull origin master
git reset --hard HEAD~1

Replace master with your desired branch.

Use git log to see to which commit you would like to revert:

git log

Personally, this has worked for me better.

Basically, what this does is pulls the latest commit, and you manually revert commits one by one. Use git log in order to see commit history.

Good points: Works as advertised. You don't have to use commit hash or pull unneeded branches.

Bad points: You need to revert commits on by one.

WARNING: Commit/stash all your local changes, because with --hard you are going to lose them. Use at your own risk!

Take note of what is printed for x. You are trying to convert an array (basically just a list) into an int. length-1 would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.

EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?

import numpy as np
import matplotlib.pyplot as plt
import datetime

time_start = datetime.datetime.now()

# My original answer
def f(x):
    rebuilt_to_plot = []
    for num in x:
        rebuilt_to_plot.append(np.int(num))
    return rebuilt_to_plot

for t in range(10000):
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f(x))

time_end = datetime.datetime.now()

# Answer by ayhan
def f_1(x):
    return np.int(x)

for t in range(10000):
    f2 = np.vectorize(f_1)
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f2(x))

time_end_2 = datetime.datetime.now()

print time_end - time_start
print time_end_2 - time_end

Some time ago I came across the following algorithm which works very well for incrementing and decrementing months on either a date or datetime.

CAVEAT: This will fail if day is not available in the new month. I use this on date objects where day == 1 always.

Python 3.x:

def increment_month(d, add=1):
    return date(d.year+(d.month+add-1)//12, (d.month+add-1) % 12+1, 1)

For Python 2.7 change the //12 to just /12 since integer division is implied.

I recently used this in a defaults file when a script started to get these useful globals:

MONTH_THIS = datetime.date.today()
MONTH_THIS = datetime.date(MONTH_THIS.year, MONTH_THIS.month, 1)

MONTH_1AGO = datetime.date(MONTH_THIS.year+(MONTH_THIS.month-2)//12,
                           (MONTH_THIS.month-2) % 12+1, 1)

MONTH_2AGO = datetime.date(MONTH_THIS.year+(MONTH_THIS.month-3)//12,
                           (MONTH_THIS.month-3) % 12+1, 1)

None of the above solutions worked for me. Append method didn't give error when i tried but it didn't solve my problem. In the end i solved my problem with data property of select2. I used json and got the array and then give it in select2 element initialize. For more detail you can see my answer at below post.

The

res/values/colors.xml.

<color name="red">#ffff0000</color>
android:background="@color/red"

example didn't work for me, but the

android:background="#(hexidecimal here without these parenthesis)"

worked for me in the relative layout element as an attribute.

This is a bit old but I ran into the requirement so here is the solution I came up with.

The Problem:

Our development team maintains many .NET web application products we are migrating to AngularJS/Bootstrap. VS2010 does not lend itself easily to custom build processes and my developers are routinely working on multiple releases of our products. Our VCS is Subversion (I know, I know. I'm trying to move to Git but my pesky marketing staff is so demanding) and a single VS solution will include several separate projects. I needed my staff to have a common method for initializing their development environment without having to install the same Node packages (gulp, bower, etc.) several times on the same machine.

TL;DR:

1. Need "npm install" to install the global Node/Bower development environment as well as all locally required packages for a .NET product.

2. Global packages should be installed only if not already installed.

3. Local links to global packages must be created automatically.

The Solution:

We already have a common development framework shared by all developers and all products so I created a NodeJS script to install the global packages when needed and create the local links. The script resides in "....\SharedFiles" relative to the product base folder:

/*******************************************************************************

Now if I want to update a global tool for our developers, I update the "packages" object and check in the new script. My developers check it out and either run it with "node npm-setup.js" or by "npm install" from any of the products under development to update the global environment. The whole thing takes 5 minutes.

In addition, to configure the environment for the a new developer, they must first only install NodeJS and GIT for Windows, reboot their computer, check out the "Shared Files" folder and any products under development, and start working.

The "package.json" for the .NET product calls this script prior to install:

{ 
"name"                    : "Books",
"description"             : "Node (npm) configuration for Books Database Web Application Tools",
"version"                 : "2.1.1",
"private"                 : true,
"scripts":
  {
  "preinstall"            : "node ../../SharedFiles/npm-setup.js links",
  "postinstall"           : "bower install"
  },
"dependencies": {}
}

Notes

• Note the script reference requires forward slashes even in a Windows environment.

• "npm ls" will give "npm ERR! extraneous:" messages for all packages locally linked because they are not listed in the "package.json" "dependencies".

Edit 1/29/16

The updated npm-setup.js script above has been modified as follows:

• Package "version" in var packages is now the "package" value passed to npm install on the command line. This was changed to allow for installing packages from somewhere other than the registered repository.

• If the package is already installed but is not the one requested, the existing package is removed and the correct one installed.

• For reasons unknown, npm will periodically throw an EBUSY error (-4082) when performing an install or link. This error is trapped and the command re-executed. The error rarely happens a second time and seems to always clear up.

This function works with variables for size and initial value it combines tbur & Filipe responses.

Function ArrayIniValue(iSize As Integer, iValue As Integer)
Dim sIndex As String
sIndex = "INDEX(Row(1:" & iSize & "),)"
ArrayIniValue = Evaluate("=Transpose(" & sIndex & "-" & sIndex & "+" & iValue & ")")
End Function

Called this way:

myArray = ArrayIniValue(350, 13)

For me, the problem was that I copied something from an example and used

<item name="android:windowTranslucentStatus">true</item>

just removing this fixed my problem.

I find that no one mentions this difference:

__getattribute__ has a default implementation, but __getattr__ does not.

class A:
    pass
a = A()
a.__getattr__ # error
a.__getattribute__ # return a method-wrapper

This has a clear meaning: since __getattribute__ has a default implementation, while __getattr__ not, clearly python encourages users to implement __getattr__.

border-collapse: separate !important; worked.

Thanks.

Remove the first / in the path. Also you don't need type="text/javascript" anymore in HTML5.

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

I knew tree was an appropriate, but I didn't have tree installed. So, I got a pretty close alternate here

find ./ | sed -e 's/[^-][^\/]*\//--/g;s/--/ |-/'

I saw this post about a month ago when I was having similar problems. I needed y-axis scrolling for a table inside of a ui dialog (yes, you heard me right). I was lucky, in that a working solution presented itself fairly quickly. However, it wasn't long before the solution took on a life of its own, but more on that later.

The problem with just setting the top level elements (thead, tfoot, and tbody) to display block, is that browser synchronization of the column sizes between the various components is quickly lost and everything packs to the smallest permissible size. Setting the widths of the columns seems like the best course of action, but without setting the widths of all the internal table components to match the total of these columns, even with a fixed table layout, there is a slight divergence between the headers and body when a scroll bar is present.

The solution for me was to set all the widths, check if a scroll bar was present, and then take the scaled widths the browser had actually decided on, and copy those to the header and footer adjusting the last column width for the size of the scroll bar. Doing this provides some fluidity to the column widths. If changes to the table's width occur, most major browsers will auto-scale the tbody column widths accordingly. All that's left is to set the header and footer column widths from their respective tbody sizes.

$table.find("> thead,> tfoot").find("> tr:first-child")
    .each(function(i,e) {
        $(e).children().each(function(i,e) {
            if (i != column_scaled_widths.length - 1) {
                $(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()));
            } else {
                $(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()) + $.position.scrollbarWidth());
            }
        });
    });

This fiddle illustrates these notions: http://jsfiddle.net/borgboyone/gbkbhngq/.

Note that a table wrapper or additional tables are not needed for y-axis scrolling alone. (X-axis scrolling does require a wrapping table.) Synchronization between the column sizes for the body and header will still be lost if the minimum pack size for either the header or body columns is encountered. A mechanism for minimum widths should be provided if resizing is an option or small table widths are expected.

The ultimate culmination from this starting point is fully realized here: http://borgboyone.github.io/jquery-ui-table/

I didn't see anyone answer this correctly. So I'm posting it here. In order to get columns to show up you need to specify the following line.

lvRegAnimals.View = View.Details;

And then add your columns after that.

lvRegAnimals.Columns.Add("Id", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);

Hope this helps anyone else looking for this answer in the future.

I created a function to check if times in an array overlap somehow:

    /**
     * Function to check if there are overlapping times in an array of \DateTime objects.
     *
     * @param $ranges
     *
     * @return \DateTime[]|bool
     */
    public function timesOverlap($ranges) {
        foreach ($ranges as $k1 => $t1) {
            foreach ($ranges as $k2 => $t2) {
                if ($k1 != $k2) {
                    /* @var \DateTime[] $t1 */
                    /* @var \DateTime[] $t2 */
                    $a = $t1[0]->getTimestamp();
                    $b = $t1[1]->getTimestamp();
                    $c = $t2[0]->getTimestamp();
                    $d = $t2[1]->getTimestamp();

                    if (($c >= $a && $c <= $b) || $d >= $a && $d <= $b) {
                        return true;
                    }
                }
            }
        }

        return false;
    }

In PHP >= 5.3 it can be done like this:

$offerArray = array_map(function($value) {
    return $value[4];
}, $offer);

An eclipse specific alternative limited to the java.library.path JVM parameter allows to set it for a specific source folder rather than for the whole jdk as proposed in another response:

1. select the source folder in which the program to start resides (usually source/test/java)
2. type alt enter to open Properties page for that folder
3. select native in the left panel
4. Edit the native path. The path can be absolute or relative to the workspace, the second being more change resilient.

For those interested on detail on why maven argline tag should be preferred to the systemProperties one, look, for example:

Pick up native JNI files in Maven test (lwjgl)

You can always try Manage Docker as a non-root user paragraph in the https://docs.docker.com/install/linux/linux-postinstall/ docs.

After doing this also if the problem persists then you can run the following command to solve it:

sudo chmod 666 /var/run/docker.sock

Generally, it means the program you are trying to run does not have a "main" method. If you are going to execute a Java program, the class being executed must have a main method:

For example, in the file Foo.java

public class Foo {
    public static void main(final String args[]) {
        System.out.println("hello");
    }
}

This program should compile and run no problem - if main was called something else, or was not static, it would generate the error you experienced.

Every executable program, regardless of language, needs an entry point, to tell the interpreter, operating system or machine where to start execution. In Java's case, this is the static method main, which is passed the parameter args[] containing the command line arguments. This method is equivalent to int main(int argc, char** argv) in C language.

Adding to tfe's answer, you can recover with this process mentioned, unless it's commits are not garbage collected. Git branch is simply a pointer to a particular commit in the commit tree. But if you delete the pointer, and the commits on that branch are not merged into other existing branch, then git treats it as dangling commits and removes them during garbage collection, which it may run automatically periodically.

If your branch wasn't merged to an existing branch, and if it was garbage collected, then you will loose all commits up until the point from where branch was forked from an existing branch.

Old thread, but just only to say: to use the classic Left(), Right(), Mid() right now you don't need to write the full path (Microsoft.VisualBasic.Strings). You can use fast and easily like this:

Strings.Right(yourString, 5)

From sun docs:

\s A whitespace character: [ \t\n\x0B\f\r]

The simplest way is to use it with regex.

Of course it is!

Give them both an id and set up the CSS accordingly:

#table1
{
    CSS for table1
}


#table2
{
    CSS for table2
}

I had to modify Lars' answer a bit, as an orphaned \ ended up in the regex, to only compare the actual host (not paying attention to the protocol or port) and I wanted to support localhost domain besides my production domain. Thus I changed the $allowed parameter to be an array.

function getCORSHeaderOrigin($allowed, $input)
{
    if ($allowed == '*') {
        return '*';
    }

    if (!is_array($allowed)) {
        $allowed = array($allowed);
    }

    foreach ($allowed as &$value) {
        $value = preg_quote($value, '/');

        if (($wildcardPos = strpos($value, '\*')) !== false) {
            $value = str_replace('\*', '(.*)', $value);
        }
    }

    $regexp = '/^(' . implode('|', $allowed) . ')$/';

    $inputHost = parse_url($input, PHP_URL_HOST);

    if ($inputHost === null || !preg_match($regexp, $inputHost, $matches)) {
        return 'none';
    }

    return $input;
}

Usage as follows:

if (isset($_SERVER['HTTP_ORIGIN'])) {
    header("Access-Control-Allow-Origin: " . getCORSHeaderOrigin(array("*.myproduction.com", "localhost"), $_SERVER['HTTP_ORIGIN']));
}

As of jQuery 1.6, you could (and some would say should) use .prop instead of .attr

$('.test').click(function(){
    alert($(this).prop('id'));
});

It is discussed further in this post: .prop() vs .attr()

Mailjet

SMTP SETTINGS

Port: 25 or 587 (some providers block port 25)

I work by changing the port after deploying the app to the server.

• In Release it worked for me: $mail->Port = 587;

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

Do you mean any specific syntax for wildcards? Usually * stands for "one or many" characters and ? stands for one.

The simplest way probably is to translate a wildcard expression into a regular expression, then use that for filtering the results.

Just put it between center tags:

<center>><Your text here>></center>

There is an infinity in the NumPy library: from numpy import inf. To get negative infinity one can simply write -inf.

The /i switch might be what your after.

From xcopy /?

/I If destination does not exist and copying more than one file, assumes that destination must be a directory.

A cross browser/version solution to determine whether an element is visible, is to add/remove a css class to the element on show/hide. The default(visible) state of the element could be for example like this:

<span id="span1" class="visible">Span text</span>

Then on hide, remove the class:

$("#span1").removeClass("visible").hide();

On show, add it again:

$("#span1").addClass("visible").show();

Then to determine whether the element is visible, use this:

if ($("#span1").hasClass("visible")) { // do something }

This also solves the performance implications, which may occur on heavy usage of the ":visible" selector, which are pointed in jQuery's documentation:

Using this selector heavily can have performance implications, as it may force the browser to re-render the page before it can determine visibility. Tracking the visibility of elements via other methods, using a class for example, can provide better performance.

Official jQuery API Documentation for ":visible" selector

Check whether the View (.ASPX File) that you have created is having the same name as mentioned in the Controller. For e.g:

 public ActionResult GetView()
 {
    return View("MyView");
 }

In this case, the aspx file should be having the name MyView.aspx instead of GetView.aspx

I think you may want renderInContext, not drawInContext. drawInContext is more a method you would override...

Note that it may not work in all views, specifically a year or so ago when I tried to use this with the live camera view it did not work.

From the Object.toString docs:

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Example:

String[] mystr ={"a","b","c"};
System.out.println("mystr.toString: " + mystr.toString());

output:- mystr.toString: [Ljava.lang.String;@13aaa14a

In case you have trouble building boost or prefer not to do that, an alternative is to download the lib files from SourceForge. The link will take you to a folder of zipped lib and dll files for version 1.51. But, you should be able to edit the link to specify the version of choice. Apparently the installer from BoostPro has some issues.

You need to define the size of file...

header('Content-Length: ' . filesize($file));

And this line is wrong:

header("Content-Disposition:inline;filename='$filename");

You messed up quotas.

One approach could be using find:

for directories

find /desired_location -type d -print0 | xargs -0 chmod 0755

for files

find /desired_location -type f -print0 | xargs -0 chmod 0644

Try using the success() call back

$http.get('/Documents/DocumentsList/' + caseId).success(function (result) {
    $scope.Documents = result;
});

But now since Documents is an array and not a promise, remove the ()

<li ng-repeat="document in Documents" ng-class="IsFiltered(document.Filtered)"> <span>
           <input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" />
        </span>
 <span>{{document.Name}}</span>

</li>

It's 257 characters. To be precise: NTFS itself does impose a maximum filename-length of several thousand characters (around 30'000 something). However, Windows imposes a 260 maximum length for the Path+Filename. The drive+folder takes up at least 3 characters, so you end up with 257.

seeing it in digital circuit domain

1. A Wire will create a wire output which can only be assigned any input by using assign statement as assign statement creates a port/pin connection and wire can be joined to the port/pin
2. A reg will create a register(D FLIP FLOP ) which gets or recieve inputs on basis of sensitivity list either it can be clock (rising or falling ) or combinational edge .

so it completely depends on your use whether you need to create a register and tick it according to sensitivity list or you want to create a port/pin assignment

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

I faced the same issue. In my case, part of my variables were in a dictionary i.e. with_dict variable (looping) and I had to run 3 commands on each item.key. This solution is more relevant where you have to use with_dict dictionary with running multiple commands (without requiring with_items)

Using with_dict and with_items in one task didn't help as it was not resolving the variables.

My task was like:

- name: Make install git source
  command: "{{ item }}"
  with_items:
    - cd {{ tools_dir }}/{{ item.value.artifact_dir }}
    - make prefix={{ tools_dir }}/{{ item.value.artifact_dir }} all
    - make prefix={{ tools_dir }}/{{ item.value.artifact_dir }} install
  with_dict: "{{ git_versions }}"

roles/git/defaults/main.yml was:

---
tool: git
default_git: git_2_6_3

git_versions:
  git_2_6_3:
    git_tar_name: git-2.6.3.tar.gz
    git_tar_dir: git-2.6.3
    git_tar_url: https://www.kernel.org/pub/software/scm/git/git-2.6.3.tar.gz

The above resulted in an error similar to the following for each {{ item }} (for 3 commands as mentioned above). As you see, the values of tools_dir is not populated (tools_dir is a variable which is defined in a common role's defaults/main.yml and also item.value.git_tar_dir value was not populated/resolved).

failed: [server01.poc.jenkins] => (item=cd {# tools_dir #}/{# item.value.git_tar_dir #}) => {"cmd": "cd '{#' tools_dir '#}/{#' item.value.git_tar_dir '#}'", "failed": true, "item": "cd {# tools_dir #}/{# item.value.git_tar_dir #}", "rc": 2}
msg: [Errno 2] No such file or directory

Solution was easy. Instead of using "COMMAND" module in Ansible, I used "Shell" module and created a a variable in roles/git/defaults/main.yml

So, now roles/git/defaults/main.yml looks like:

---
tool: git
default_git: git_2_6_3

git_versions:
  git_2_6_3:
    git_tar_name: git-2.6.3.tar.gz
    git_tar_dir: git-2.6.3
    git_tar_url: https://www.kernel.org/pub/software/scm/git/git-2.6.3.tar.gz

#git_pre_requisites_install_cmds: "cd {{ tools_dir }}/{{ item.value.git_tar_dir }} && make prefix={{ tools_dir }}/{{ item.value.git_tar_dir }} all && make prefix={{ tools_dir }}/{{ item.value.git_tar_dir }} install"

#or use this if you want git installation to work in ~/tools/git-x.x.x
git_pre_requisites_install_cmds: "cd {{ tools_dir }}/{{ item.value.git_tar_dir }} && make prefix=`pwd` all && make prefix=`pwd` install"

#or use this if you want git installation to use the default prefix during make 
#git_pre_requisites_install_cmds: "cd {{ tools_dir }}/{{ item.value.git_tar_dir }} && make all && make install"

and the task roles/git/tasks/main.yml looks like:

- name: Make install from git source
  shell: "{{ git_pre_requisites_install_cmds }}"
  become_user: "{{ build_user }}"
  with_dict: "{{ git_versions }}"
  tags:
    - koba

This time, the values got successfully substituted as the module was "SHELL" and ansible output echoed the correct values. This didn't require with_items: loop.

"cmd": "cd ~/tools/git-2.6.3 && make prefix=/home/giga/tools/git-2.6.3 all && make prefix=/home/giga/tools/git-2.6.3 install",

You can also use C's lroundf(myFloat).

An incredibly useful tip: In Xcode's editor, type your code as say

myInt = roundf(someFloat);

then control/right-click on roundf and Jump to definition (or simply command-click).

You will then clearly see the very long list of the functions available to you. (It's impossible to remember them all, so just use this trick.)

For example, in the example at hand it's likely that lrintf is what you want.

A further tip: to get documentation on those many functions. In your Terminal.app (or any shell - nothing to do with Xcode, just the normal Terminal.app) simply type man lrintf and it will give you full info. Hope it helps someone.

You can use std::ifstream, funcion like is_open, fail, for example as below code (the cout "open" means file exist or not):

cited from this answer

namedtuples are immutable, just like standard tuples. You have two choices:

1. Use a different data structure, e.g. a class (or just a dictionary); or
2. Instead of updating the structure, replace it.

The former would look like:

class N(object):

    def __init__(self, ind, set, v):
        self.ind = ind
        self.set = set
        self.v = v

And the latter:

item = items[node.ind]
items[node.ind] = N(item.ind, item.set, node.v)

Edit: if you want the latter, Ignacio's answer does the same thing more neatly using baked-in functionality.

The best approach for you to communicate between the two controllers is to use events.

See the scope documentation

In this check out $on, $broadcast and $emit.

You don't need to "tell" Terminal to do anything. AppleScript can do shell scripts directly.

set theDir to "~/Desktop/"
do shell script "touch " & theDir &"SomeFile.txt"

or whatever ...

Horizontal to vertical split

Ctrl+W for window command, followed by Shift+H or Shift+L

Vertical to horizontal split

Ctrl+W for window command, followed by Shift+K or Shift+J

Both solutions apply when only two windows exist.

Open help in a vertical split by default

Add both of these lines to .vimrc:

cabbrev help vert help
cabbrev h vert h

:vert[ical] {cmd} always executes the cmd in a vertically split window.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

There are some problems when logical vector contains NA values.
See for example:

z <- c(TRUE, FALSE, NA)
sum(z) # gives you NA
table(z)["TRUE"] # gives you 1
length(z[z == TRUE]) # f3lix answer, gives you 2 (because NA indexing returns values)

So I think the safest is to use na.rm = TRUE:

sum(z, na.rm = TRUE) # best way to count TRUE values

(which gives 1). I think that table solution is less efficient (look at the code of table function).

Also, you should be careful with the "table" solution, in case there are no TRUE values in the logical vector. Suppose z <- c(NA, FALSE, NA) or simply z <- c(FALSE, FALSE), then table(z)["TRUE"] gives you NA for both cases.

You can use regexp_substr(). Example:

create or replace type splitTable_Type is table of varchar2(100);

declare
    l_split_table splitTable_Type;
begin
  select
      regexp_substr('SMITH,ALLEN,WARD,JONES','[^,]+', 1, level)
  bulk collect into
      l_split_table
  from dual
  connect by
      regexp_substr('SMITH,ALLEN,WARD,JONES', '[^,]+', 1, level) is not null;
end;

The query iterates through the comma separated string, searches for the comma (,) and then splits the string by treating the comma as delimiter. It returns the string as a row, whenever it hits a delimiter.

level in statement regexp_substr('SMITH,ALLEN,WARD,JONES','[^,]+', 1, level) refers to a pseudocolumn in Oracle which is used in a hierarchical query to identify the hierarchy level in numeric format: level in connect by

Try This:

<img class="img-responsive" src="assets/img/google-body-ads.png">

if sys.platform[:3] == "win":
    # First try to use the default Windows browser
    register("windows-default", WindowsDefault)

    # Detect some common Windows browsers, fallback to IE
    iexplore = os.path.join(os.environ.get("PROGRAMFILES", "C:\\Program Files"),
                            "Mozilla Firefox\\FIREFOX.EXE")
    for browser in ("firefox", "firebird", "seamonkey", "mozilla",
                    "netscape", "opera", iexplore):
        if shutil.which(browser):
            register(browser, None, BackgroundBrowser(browser))

100% Work....See line number 535-545..Change the path of iexplore to firefox or Chrome According to your requirement... in my case change path I Mention in the above code for firefox setting......

You can initialize it just like any list:

public List<ContactNumber> ContactNumbers { get; set; }

public Human(int id)
{
    Id = id;
    ContactNumbers = new List<ContactNumber>();
}

public Human(int id, string address, string name) :this(id)
{
    Address = address;
    Name = name;
    // no need to initialize the list here since you're
    // already calling the single parameter constructor
}       

However, I would even go a step further and make the setter private since you often don't need to set the list, but just access/modify its contents:

public List<ContactNumber> ContactNumbers { get; private set; }

A more language-independent choice for string literals is the international standard ISO 8601 format "YYYY-MM-DDThh:mm:ss". I used the SQL query below to test the format, and it does indeed work in all SQL languages in sys.syslanguages:

declare @sql nvarchar(4000)

declare @LangID smallint
declare @Alias sysname

declare @MaxLangID smallint
select @MaxLangID = max(langid) from sys.syslanguages

set @LangID = 0

while @LangID <= @MaxLangID
begin

    select @Alias = alias
    from sys.syslanguages
    where langid = @LangID

    if @Alias is not null
    begin

        begin try
            set @sql = N'declare @TestLang table (langdate datetime)
    set language ''' + @alias + N''';
    insert into @TestLang (langdate)
    values (''2012-06-18T10:34:09'')'
            print 'Testing ' + @Alias

            exec sp_executesql @sql
        end try
        begin catch
            print 'Error in language ' + @Alias
            print ERROR_MESSAGE()
        end catch
    end

    select @LangID = min(langid)
    from sys.syslanguages
    where langid > @LangID
end

According to the String Literal Date and Time Formats section in Microsoft TechNet, the standard ANSI Standard SQL date format "YYYY-MM-DD hh:mm:ss" is supposed to be "multi-language". However, using the same query, the ANSI format does not work in all SQL languages.

For example, in Danish, you will many errors like the following:

Error in language Danish The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

If you want to build a query in C# to run on SQL Server, and you need to pass a date in the ISO 8601 format, use the Sortable "s" format specifier:

string.Format("select convert(datetime2, '{0:s}'", DateTime.Now);

The following function shows why and is capable for working out the difference:

function test() {
        var myObj = {};
        console.log(myObj.myProperty);
        myObj.myProperty = null;
        console.log(myObj.myProperty);
}

If you call

test();

You're getting

undefined

null

The first console.log(...) tries to get myProperty from myObj while it is not yet defined - so it gets back "undefined". After assigning null to it, the second console.log(...) returns obviously "null" because myProperty exists, but it has the value null assigned to it.

In order to be able to query this difference, JavaScript has null and undefined: While null is - just like in other languages an object, undefined cannot be an object because there is no instance (even not a null instance) available.

ps aux | awk '{print $2, $4, $11}' | sort -k2rn | head -n 10

(Adding -n numeric flag to sort command.)

Probably not exactly what you're looking for since you say it's "dynamic data" but given your example string, this also works:

? "abcdxxx".TrimEnd('x');
"abc"

Can you test with surefire 2.6 and either configure Surefire with <testFailureIgnore>true</testFailureIgnore>.

Or on the command line:

mvn install -Dmaven.test.failure.ignore=true

Maven is a build tool. Along with Ant or Gradle are Javas tools for building.
If you are a newbie in Java though just build using your IDE since Maven has a steep learning curve.

 <c:forEach items="${sessionScope.empL}" var="emp">
            <tr>
                <td>Employee ID: <c:out value="${emp.eid}"/></td>
                <td>Employee Pass: <c:out value="${emp.ename}"/></td>  
            </tr>

Here is a solution in php that:

• copies the directories (not recursively, only one level)
• preserves permissions
• unlike the rsync solution, is fast even with directories containing thousands of files as it does not even go into the folders
• has no problems with spaces
• should be easy to read and adjust

Create a file like syncDirs.php with this content:

<?php
foreach (new DirectoryIterator($argv[1]) as $f) {
    if($f->isDot() || !$f->isDir()) continue;
        mkdir($argv[2].'/'.$f->getFilename(), $f->getPerms());
        chown($argv[2].'/'.$f->getFilename(), $f->getOwner());
        chgrp($argv[2].'/'.$f->getFilename(), $f->getGroup());
}

Run it as user that has enough rights:

sudo php syncDirs.php /var/source /var/destination

Use scrollTop() to get or set the scroll position.

For the IBM JVM, the command is the following:

You are trying to read the set value before Angular is done assigning.

Demo:

var testController = function ($scope, $timeout) {
    console.log('test');
    $timeout(function(){
        console.log($scope.testInput);
    },1000);
}

Ideally you should use $watch as suggested by @Beterraba to get rid of the timer:

var testController = function ($scope) {
    console.log('test');
    $scope.$watch("testInput", function(){
        console.log($scope.testInput);
    });
}

For the substition impaired here is a real example from GitHub.com to a local directory:

svn export https://github.com/rdcarp/playing-cards/trunk/PumpkinSoup.PlayingCards.Interfaces /temp/SvnExport/Washburn

See: Download a single folder or directory from a GitHub repo for more details.

We can solve this using Hooks:

First we'll need a timeout hook for the delay.

This one is inspired by Dan Abramov's useInterval hook (see Dan's blog post for an in depth explanation), the differences being:

1. we use we setTimeout not setInterval
2. we return a reset function allowing us to restart the timer at any time

import { useEffect, useRef, useCallback } from 'react';_x000D_
_x000D_
const useTimeout = (callback, delay) => {_x000D_
  // save id in a ref_x000D_
  const timeoutId = useRef('');_x000D_
_x000D_
  // save callback as a ref so we can update the timeout callback without resetting the clock_x000D_
  const savedCallback = useRef();_x000D_
  useEffect(_x000D_
    () => {_x000D_
      savedCallback.current = callback;_x000D_
    },_x000D_
    [callback],_x000D_
  );_x000D_
_x000D_
  // clear the timeout and start a new one, updating the timeoutId ref_x000D_
  const reset = useCallback(_x000D_
    () => {_x000D_
      clearTimeout(timeoutId.current);_x000D_
_x000D_
      const id = setTimeout(savedCallback.current, delay);_x000D_
      timeoutId.current = id;_x000D_
    },_x000D_
    [delay],_x000D_
  );_x000D_
_x000D_
  useEffect(_x000D_
    () => {_x000D_
      if (delay !== null) {_x000D_
        reset();_x000D_
_x000D_
        return () => clearTimeout(timeoutId.current);_x000D_
      }_x000D_
    },_x000D_
    [delay, reset],_x000D_
  );_x000D_
_x000D_
  return { reset };_x000D_
};

and now we need a hook which will capture previous children and use our useTimeout hook to swap in the new children after a delay

import { useState, useEffect } from 'react';_x000D_
_x000D_
const useDelayNextChildren = (children, delay) => {_x000D_
  const [finalChildren, setFinalChildren] = useState(children);_x000D_
_x000D_
  const { reset } = useTimeout(() => {_x000D_
    setFinalChildren(children);_x000D_
  }, delay);_x000D_
_x000D_
  useEffect(_x000D_
    () => {_x000D_
      reset();_x000D_
    },_x000D_
    [reset, children],_x000D_
  );_x000D_
_x000D_
  return finalChildren || children || null;_x000D_
};

Note that the useTimeout callback will always have the latest children, so even if we attempt to render multiple different new children within the delay time, we'll always get the latest children once the timeout finally completes.

Now in your case, we want to also delay the initial render, so we make this change:

const useDelayNextChildren = (children, delay) => {_x000D_
  const [finalChildren, setFinalChildren] = useState(null); // initial state set to null_x000D_
_x000D_
  // ... stays the same_x000D_
_x000D_
  return finalChildren || null;  // remove children from return_x000D_
};

and using the above hook, your entire child component becomes

import React, { memo } from 'react';_x000D_
import { useDelayNextChildren } from 'hooks';_x000D_
_x000D_
const Child = ({ delay }) => useDelayNextChildren(_x000D_
  <div>_x000D_
    ... Child JSX goes here_x000D_
    ... etc_x000D_
  </div>_x000D_
  , delay_x000D_
);_x000D_
_x000D_
export default memo(Child);

or if you prefer: ( dont say i havent given you enough code ;) )

const Child = ({ delay }) => {_x000D_
  const render = <div>... Child JSX goes here ... etc</div>;_x000D_
_x000D_
  return useDelayNextChildren(render, delay);_x000D_
};

which will work exactly the same in the Parent render function as in the accepted answer

...

except the delay will be the same on every subsequent render too,

AND we used hooks, so that stateful logic is reusable across any component

...

...

use hooks. :D

You can split that string on , and directly get a list:

mStr = 'A,B,C,D,E'
list1 = mStr.split(',')
print(list1)

Output:

['A', 'B', 'C', 'D', 'E']

You can also convert it to an n-tuple:

print(tuple(list1))

Output:

('A', 'B', 'C', 'D', 'E')

http://www.postgresql.org/docs/current/static/functions-datetime.html shows operators you can use for working with dates and times (and intervals).

So you want

SELECT "date"
FROM "Table"
WHERE "date" > (CURRENT_DATE - INTERVAL '10 days');

The operators/functions above are documented in detail:

• CURRENT_DATE
• INTERVAL '10 days'

1 You can use string.Replace method

var sample = "testtesttesttest#replace#testtesttest";
var result = sample.Replace("#replace#", yourValue);

2 You can also use string.Format

var result = string.Format("your right part {0} Your left Part", yourValue);

3 You can use Regex class

 <div class="custom-control custom-checkbox left">
    <ul class="list-unstyled">
        <li>
         <label class="btn btn-secondary text-left" style="width:100%;text-align:left;padding:2px;">
           <input type="checkbox" style="zoom:1.7;vertical-align:bottom;" asp-for="@Model[i].IsChecked" class="custom-control-input" /> @Model[i].Title
         </label>
        </li>
     </ul>
</div>

Based on reading several Stackoverflow questions and answers on squashing, I think this is a good one liner to squash all commits on a branch:

git reset --soft $(git merge-base master YOUR_BRANCH) && git commit -am "YOUR COMMIT MESSAGE" && git rebase -i master

This is assuming master is the base branch.

getElementById

Return Value: An Element Object, representing an element with the specified ID. Returns null if no elements with the specified ID exists see: https://www.w3schools.com/jsref/met_document_getelementbyid.asp

Truthy vs Falsy

In JavaScript, a truthy value is a value that is considered true when evaluated in a Boolean context. All values are truthy unless they are defined as falsy (i.e., except for false, 0, "", null, undefined, and NaN). see: https://developer.mozilla.org/en-US/docs/Glossary/Truthy

When the dom element is not found in the document it will return null. null is a Falsy and can be used as boolean expression in the if statement.

var myElement = document.getElementById("myElement");
if(myElement){
  // Element exists
}

Set the items into display: inline and use :after:

.text span { display: inline }
.break-after:after { content: '\A'; white-space:pre; }

and add the class into your html spans:

<span class="medium break-after">We</span>

It's very easy to write that yourself, and that way you have more control over things.. As the other answers say, TypeScript is not aimed at adding runtime types or functionality.

Map:

class Map<T> {
    private items: { [key: string]: T };

    constructor() {
        this.items = {};
    }

    add(key: string, value: T): void {
        this.items[key] = value;
    }

    has(key: string): boolean {
        return key in this.items;
    }

    get(key: string): T {
        return this.items[key];
    }
}

List:

class List<T> {
    private items: Array<T>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(value);
    }

    get(index: number): T {
        return this.items[index];
    }
}

I haven't tested (or even tried to compile) this code, but it should give you a starting point.. you can of course then change what ever you want and add the functionality that YOU need...

As for your "special needs" from the List, I see no reason why to implement a linked list, since the javascript array lets you add and remove items.
Here's a modified version of the List to handle the get prev/next from the element itself:

class ListItem<T> {
    private list: List<T>;
    private index: number;

    public value: T;

    constructor(list: List<T>, value: T, index: number) {
        this.list = list;
        this.index = index;
        this.value = value;
    }

    prev(): ListItem<T> {
        return this.list.get(this.index - 1);
    }

    next(): ListItem<T> {
        return this.list.get(this.index + 1);   
    }
}

class List<T> {
    private items: Array<ListItem<T>>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(new ListItem<T>(this, value, this.size()));
    }

    get(index: number): ListItem<T> {
        return this.items[index];
    }
}

Here too you're looking at untested code..

Hope this helps.

Edit - as this answer still gets some attention

Javascript has a native Map object so there's no need to create your own:

let map = new Map();
map.set("key1", "value1");
console.log(map.get("key1")); // value1

I wanted my XAML to remain as elegant as possible so I created a class to wrap the bool which resides in one of my shared libraries, the implicit operators allow the class to be used as a bool in code-behind seamlessly

public class InvertableBool
{
    private bool value = false;

    public bool Value { get { return value; } }
    public bool Invert { get { return !value; } }

    public InvertableBool(bool b)
    {
        value = b;
    }

    public static implicit operator InvertableBool(bool b)
    {
        return new InvertableBool(b);
    }

    public static implicit operator bool(InvertableBool b)
    {
        return b.value;
    }

}

The only changes needed to your project are to make the property you want to invert return this instead of bool

    public InvertableBool IsActive 
    { 
        get 
        { 
            return true; 
        } 
    }

And in the XAML postfix the binding with either Value or Invert

IsEnabled="{Binding IsActive.Value}"

IsEnabled="{Binding IsActive.Invert}"

Martijn's method as a prototype function:

String.prototype.escape = function() {
    var tagsToReplace = {
        '&': '&',
        '<': '&lt;',
        '>': '&gt;'
    };
    return this.replace(/[&<>]/g, function(tag) {
        return tagsToReplace[tag] || tag;
    });
};

var a = "<abc>";
var b = a.escape(); // "&lt;abc&gt;"

It is easy to assign repeated values to an array:

x(1:10) = 5;

If you want to generate the array of elements inline in a statement try something like this:

ones(1,10) * 5

or with repmat

repmat(5, 1, 10)

I think your cron is not correct. According to what you described, you may need to change cron schedule to

*/5 * * * *

What you put in your schedule now mean it will poll the SCM at 5 past of every hour.

Another solution I found was just to encode the result as Windows Code Page 1252 (Windows-1252 or CP1252). This would be done, for example by setting Content-Type appropriately to something like text/csv; charset=Windows-1252 and setting the character encoding of the response stream similarly.

In the progress dialog, user cannot do any kind of work. All the background processes are stopped during progress dialog. So, It is advisable to user progress-bar instead of progress dialog.

Here is settings.xml --> C:\maven\conf\settings.xml

For your code

var mytextvalue = document.getElementById("mytext");

mytextvalue will contain null if you have a document.write() statement before this code. So remove the document.write statement and you should get a proper text object in the variable mytextvalue.

This is caused by document.write changing the document.

Not so graceful, but the very much simple in implementation solution - using global variable.

In the "first" file:

window.myApp = angular.module("myApp", [])
....

in the "second" , "third", etc:

myApp.controller('MyController', function($scope) {
    .... 
    }); 

Print the full path (also called resolved path) with:

realpath README.md

In interactive mode you can use shell expansion to list all files in the directory with their full paths:

realpath *

If you're programming a bash script, I guess you'll have a variable for the individual file names.

Not sure if this is a feature or a bug but this worked for us:

git commit '' -m "Message"

Note the empty file list ''. Git interprets this to commit all modified tracked files, even if they are not staged, and ignore untracked files.

2. smooth effect from right to left

   Create a file called animation_enter.xml and animation_leave.xml in res/anim

   animation_enter.xml

      <set xmlns:android="http://schemas.android.com/apk/res/android"
       android:shareInterpolator="false">
       <translate android:fromXDelta="-100%" android:toXDelta="0%"
           android:fromYDelta="0%" android:toYDelta="0%"
           android:duration="700"/>
      </set>
   

   animation_leave.xml

     <set xmlns:android="http://schemas.android.com/apk/res/android"
       android:shareInterpolator="false">
       <translate
           android:fromXDelta="0%" android:toXDelta="100%"
           android:fromYDelta="0%" android:toYDelta="0%"
           android:duration="700" />
     </set>
   

3. Navigate from one activity to second Activity

      Intent intent_next=new Intent(One_Activity.this,Second_Activity.class);
      overridePendingTransition(R.anim.slide_in_right,R.anim.slide_out_right);
      startActivity(intent_next);
    finish();
   

   4.On back press event or Navigate from second activity to one Activity

    Intent home_intent = new Intent(Second_Activity.this, One_Activity.class);
    overridePendingTransition(R.anim.animation_enter, R.anim.animation_leave);
    startActivity(home_intent);
    finish();
   

Yes, right click the project. Click Run as then Run Configurations. You can change the parameters passed to the JVM in the Arguments tab in the VM Arguments box.

That configuration can then be used as the default when running the project.

It's usually based on significant figures of both the exponent and significand in base 2, not base 10. From what I can tell in the C99 standard, however, there is no specified precision for floats and doubles (other than the fact that 1 and 1 + 1E-5 / 1 + 1E-7 are distinguishable [float and double repsectively]). However, the number of significant figures is left to the implementer (as well as which base they use internally, so in other words, an implementation could decide to make it based on 18 digits of precision in base 3). [1]

If you need to know these values, the constants FLT_RADIX and FLT_MANT_DIG (and DBL_MANT_DIG / LDBL_MANT_DIG) are defined in float.h.

The reason it's called a double is because the number of bytes used to store it is double the number of a float (but this includes both the exponent and significand). The IEEE 754 standard (used by most compilers) allocate relatively more bits for the significand than the exponent (23 to 9 for float vs. 52 to 12 for double), which is why the precision is more than doubled.

This is how I limit the results in MS SQL Server 2012:

SELECT * 
FROM table1
ORDER BY columnName
  OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY

NOTE: OFFSET can only be used with or in tandem to ORDER BY.

To explain the code line OFFSET xx ROWS FETCH NEXT yy ROW ONLY

The xx is the record/row number you want to start pulling from in the table, i.e: If there are 40 records in table 1, the code above will start pulling from row 10.

The yy is the number of records/rows you want to pull from the table.

To build on the previous example: If table 1 has 40 records and you began pulling from row 10 and grab the NEXT set of 10 (yy). That would mean, the code above will pull the records from table 1 starting at row 10 and ending at 20. Thus pulling rows 10 - 20.

The command

$ arch    

is equivalent to

$ uname -m

but is twice as fast to type

If you are in Javascript already, couldn't you just use Date.Parse() to validate a date instead of using regEx.

RegEx for date is actually unwieldy and hard to get right especially with leap years and all.

I was experiencing this same problem. In my instance the send mail was timing out because my Exchange server was relaying email to a server on the internet. That server had exceeded it's bandwidth quota. Apparently php mailer has some built in timeout and it wasn't long enough to see the actual message.

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

data

names = ['Prashobh','Abraham','Anil','Sam','Natasha','Marry','Zian','karan']

You can achieve this by creating a simple pipe

<input type="text" [(ngModel)]="queryString" id="search" placeholder="Search to type">

Pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
    name: 'FilterPipe',
})
export class FilterPipe implements PipeTransform {
    transform(value: any, input: string) {
        if (input) {
            input = input.toLowerCase();
            return value.filter(function (el: any) {
                return el.toLowerCase().indexOf(input) > -1;
            })
        }
        return value;
    }
}

This will filter the result based on the search term

from python 3.4 you may use :

import pathlib

def delete_folder(pth) :
    for sub in pth.iterdir() :
        if sub.is_dir() :
            delete_folder(sub)
        else :
            sub.unlink()
    pth.rmdir() # if you just want to delete the dir content but not the dir itself, remove this line

where pth is a pathlib.Path instance. Nice, but may not be the fastest.

Google Chrome does not allow to load local resources because of the security. Chrome need http url. Internet Explorer and Edge allows to load local resources, but Safari, Chrome, and Firefox doesn't allows to load local resources.

Go to file location and start the Python Server from there.

python -m SimpleHttpServer

then put that url into function:

function run(){
var URL = "http://172.271.1.20:8000/" /* http://0.0.0.0:8000/ or http://127.0.0.1:8000/; */
window.open(URL, null);
}

Change

test=substring(i,j,*s);

to

test=substring(i,j,s);  

Also, you need to forward declare substring:

char *substring(int i,int j,char *ch);

In my case, my site was hosted on shared hosting and there was a resource over usage not even relating to my database, thus my database was locked down, the hosting panel was Plesk

This the solution i'm using even if the leading zero are there.

 WHERE Employee.Empid=emp3.empid

It depends on the nature of the method and how it will be used. If it is normal behavior that the object may not be found, then return null. If it is normal behavior that the object is always found, throw an exception.

As a rule of thumb, use exceptions only for when something exceptional occurs. Don't write the code in such a way that exception throwing and catching is part of its normal operation.

Either one should work OK. In fact, System.Threading.Timer uses System.Timers.Timer internally.

Having said that, it's easy to misuse System.Timers.Timer. If you don't store the Timer object in a variable somewhere, then it is liable to be garbage collected. If that happens, your timer will no longer fire. Call the Dispose method to stop the timer, or use the System.Threading.Timer class, which is a slightly nicer wrapper.

What problems have you seen so far?

A key issue here is that this loop iterates over the rows (1st dimension) of B:

In [258]: B
Out[258]: 
array([[ 0,  1,  2],
       [ 3,  4,  5],
       [ 6,  7,  8],
       [ 9, 10, 11]])
In [259]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b += 1
     ...:     print(b)
     ...:     
[0 1 2] =>[1 2 3]
[3 4 5] =>[4 5 6]
[6 7 8] =>[7 8 9]
[ 9 10 11] =>[10 11 12]

Thus the += is acting on a mutable object, an array.

This is implied in the other answers, but easily missed if your focus is on the a = a+1 reassignment.

I could also make an in-place change to b with [:] indexing, or even something fancier, b[1:]=0:

In [260]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b[:] = b * 2

[1 2 3] =>[2 4 6]
[4 5 6] =>[ 8 10 12]
[7 8 9] =>[14 16 18]
[10 11 12] =>[20 22 24]

Of course with a 2d array like B we usually don't need to iterate on the rows. Many operations that work on a single of B also work on the whole thing. B += 1, B[1:] = 0, etc.

From a Microsoft's script:

DECLARE @dbname nvarchar(128)

WHERE ('[' + name + ']' = @dbname 
OR name = @dbname)))

-- code mine :)
PRINT 'db exists'

If you are looking for UML sequence diagrams, try searching for UML Sequence in the search box and add them.

• Search for UML Sequence in the search box -> Select all shapes and add to My shapes (user defined name).

You can either browse through My shapes to access them. They will be available in the in the sidebar nevertheless once you search.

find is the common tool for this kind of task :

find ./my_dir -mtime +10 -type f -delete

EXPLANATIONS

• ./my_dir your directory (replace with your own)
• -mtime +10 older than 10 days
• -type f only files
• -delete no surprise. Remove it to test your find filter before executing the whole command

And take care that ./my_dir exists to avoid bad surprises !

I was having Same error. While I run Reactjs app. What I do is just remove the node_modules folder and type and install node_modules again. This remove the error.

The most concise solution I have found uses Sympy: https://www.geeksforgeeks.org/python-sympy-line-intersection-method/

# import sympy and Point, Line 
from sympy import Point, Line 
  
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(7, 7) 
l1 = Line(p1, p2) 
  
# using intersection() method 
showIntersection = l1.intersection(p3) 
  
print(showIntersection)

I would suggest to remove the rows from the underlying DataTable, or if you don't need the datatable anymore, set the datasource to null.

It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.

To know your bindings go to the "Keyboard Shortcuts" settings and search for "Go to File"

I make a link. A link is a link. A link navigates to another page. That is what links are for and everybody understands that. So Method 3 is the only correct method in my book.

I wouldn't want my link to look like a button at all, and when I do, I still think functionality is more important than looks.

Buttons are less accessible, not only due to the need of Javascript, but also because tools for the visually impaired may not understand this Javascript enhanced button well.

Method 4 would work as well, but it is more a trick than a real functionality. You abuse a form to post 'nothing' to this other page. It's not clean.

Use this

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.someplace.com");
ResponseHandler<String> resHandler = new BasicResponseHandler();
String page = httpClient.execute(httpGet, resHandler);

This can be used to grab the whole webpage as a string of html, i.e., "<html>...</html>"

While you asked how to kill a window resp. pane, I often wouldn't want to kill it but simply to get it back to a working state (the layout of panes is of importance to me, killing a pane destroys it so I must recreate it); tmux provides the respawn commands to that effect: respawn-pane resp. respawn-window. Just that people like me may find this solution here.

Example - sending some data encoded as JSON as a POST data:

import json
import urllib2
data = json.dumps([1, 2, 3])
f = urllib2.urlopen(url, data)
response = f.read()
f.close()

$("#yourdivid textarea, #yourdivid input, #yourdivid select").attr('disabled',true);

To diagnose it, follow this answer.

But to fix it, knowing you are the only one changing it, do:
1 - backup your project (I did only the files on git, ./src folder)
2 - git pull
3 - restore you backup over the many "messed" files (with merge indicators)

I tried git pull -s recursive -X ours but didnt work the way I wanted, it could be an option tho, but backup first!!!

Make sure the differences/changes (at git gui) are none. This is my case, there is nothing to merge at all, but github keeps saying I should merge...

May I suggest trying to use in else if statement in your if/else statement. And if you don't want to run any code that not under any conditions you want you can just leave the else out at the end of the statement. else if can also be used for any number of diversion paths that need things to be a certain condition for each.

if(condition 1){

} else if (condition 2) {

}else {

}

This is a one-liner. It adds a line to the .bashrc. Tha line is going to check if the directory has already been added to the path and append if not. This will prevent duplicating your directory in the path every time you source .bashrc.

echo "[[ \":\$PATH:\" != *\":$(pwd)/path/to/add:\"* ]] && export PATH=\"\${PATH:+\${PATH}}:$(pwd)/path/to/add\"" >> ~/.bashrc

source ~/.bashrc

I suggest forget the pre and just put it in a textarea.

Your indenting will remain and your code wont get word-wrapped in the middle of a path or something.

Easier to select text range in a text area too if you want to copy to clipboard.

The following is a php excerpt so if your not in php then the way you pack the html special chars will vary.

<textarea style="font-family:monospace;" onfocus="copyClipboard(this);"><?=htmlspecialchars($codeBlock);?></textarea>

For info on how to copy text to the clipboard in js see: How do I copy to the clipboard in JavaScript? .

However...

I just inspected the stackoverflow code blocks and they wrap in a <code> tag wrapped in <pre> tag with css ...

code {
  background-color: #EEEEEE;
  font-family: Consolas,Menlo,Monaco,Lucida Console,Liberation Mono,DejaVu Sans Mono,Bitstream Vera Sans Mono,Courier New,monospace,serif;
}
pre {
  background-color: #EEEEEE;
  font-family: Consolas,Menlo,Monaco,Lucida Console,Liberation Mono,DejaVu Sans Mono,Bitstream Vera Sans Mono,Courier New,monospace,serif;
  margin-bottom: 10px;
  max-height: 600px;
  overflow: auto;
  padding: 5px;
  width: auto;
}

Also the content of the stackoverflow code blocks is syntax highlighted using (I think) http://code.google.com/p/google-code-prettify/ .

Its a nice setup but Im just going with textareas for now.

Your ComboBox is trying to bind to bind to GridItem[x].CompanyItems, which doesn't exist.

Your RelativeBinding is close, however it needs to bind to DataContext.CompanyItems because Window.CompanyItems does not exist

<input type="submit" name="submit" value="submit" onclick="return confirm('Are you sure?');"/> you can perform this action on Button too!

I believe this won't work because you are using a console application and there is no Event Loop running. An Event Loop / Message Pump used for event handling is setup automatically when a Winforms application is created, but not for a console app.

If you want to run the script directly, you can:

1. Add the FolderA's path to the environment variable (PYTHONPATH).
2. Add the path to sys.path in the your script.

Then:

Cannot open backup device 'c:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Backup\ C:\HostingSpaces\dbname_jun14_2010_new.bak'

The error is quite self-explanatory. The file C:\program files\...\Backup \c:\Hosting...\ is incorrectly formatted. This is quite obvious if you inspect the file name. Perhaps ommit the extra space in your backup statement?

BACKUP DATABASE go4sharepoint_1384_8481

If the input field has a class name formData use this : $(".formData").val("data")

If the input field has an id attribute name formData use this : $("#formData").val("data")

If the input name is given use this : $("input[name='formData']").val("data")

You can also mention the type. Then it will refer to all the inputs of that type and the given class name: $("input[type='text'].formData").val("data")

When you convert expressions from one type to another, in many cases there will be a need within a stored procedure or other routine to convert data from a datetime type to a varchar type. The Convert function is used for such things. The CONVERT() function can be used to display date/time data in various formats.

Syntax

CONVERT(data_type(length), expression, style)

Style - style values for datetime or smalldatetime conversion to character data. Add 100 to a style value to get a four-place year that includes the century (yyyy).

Example 1

take a style value 108 which defines the following format:

hh:mm:ss

Now use the above style in the following query:

select convert(varchar(20),GETDATE(),108) 

Example 2

we use the style value 107 which defines the following format:

Mon dd, yy

Now use that style in the following query:

select convert(varchar(20),GETDATE(),107) 

Similarly

style-106 for Day,Month,Year (26 Sep 2013)
style-6 for Day, Month, Year (26 Sep 13)
style-113 for Day,Month,Year, Timestamp (26 Sep 2013 14:11:53:300)

The html_safe version works well in Rails 4...

<%= "<center style=\"color: green; font-size: 1.1em\" > Administrators only </center>".html_safe if current_user.admin? %
>

Use System.Security.Principal.WindowsIdentity.GetCurrent().Name.

This will get the current logged-in Windows user.

If the format is that simple (a space separates the number from the rest) then

int(str1.split()[0])

would do it

It may be "better" to not use attach at all. On the plus side, you can save some typing if you use attach. Let's say your dataset is called mydata and you have variables called v1, v2, and v3. If you don't attach mydata, then you will type mean(mydata$v1) to get the mean of v1. If you do attach mydata, then you will type mean(v1) to get the mean of v1. But, if you don't detach the mydata dataset (every time), you'll get the message about the objects being masked going forward.

Solution 1 (assuming you want to attach):

1. Use detach every time.
2. See Dan Tarr's response if you already have the data attached (and it may be in the global environment several times). Then, in the future, use detach every time.

Solution 2

Don't use attach. Instead, include the dataset name every time you refer to a variable. The form is mydata$v1 (name of data set, dollar sign, name of variable).

As for me, I used solution 1 a lot in the past, but I've moved to solution 2. It's a bit more typing in the beginning, but if you are going to use the code multiple times, it just seems cleaner.

For example, you can define a layout file which contains a EditText element.

<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/searchfield"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:inputType="textFilter" >

</EditText> 

you can do

public class MainActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ActionBar actionBar = getActionBar();
    // add the custom view to the action bar
    actionBar.setCustomView(R.layout.actionbar_view);
    EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
    search.setOnEditorActionListener(new OnEditorActionListener() {

      @Override
      public boolean onEditorAction(TextView v, int actionId,
          KeyEvent event) {
        Toast.makeText(MainActivity.this, "Search triggered",
            Toast.LENGTH_LONG).show();
        return false;
      }
    });
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
        | ActionBar.DISPLAY_SHOW_HOME);


    }

You should configure offHeap memory settings as shown below:

val spark = SparkSession
     .builder()
     .master("local[*]")
     .config("spark.executor.memory", "70g")
     .config("spark.driver.memory", "50g")
     .config("spark.memory.offHeap.enabled",true)
     .config("spark.memory.offHeap.size","16g")   
     .appName("sampleCodeForReference")
     .getOrCreate()

Give the driver memory and executor memory as per your machines RAM availability. You can increase the offHeap size if you are still facing the OutofMemory issue.

You could also do that:

In package.json:

"scripts": {
    "cool": "./cool.js"
}

In cool.js:

 console.log({ myVar: process.env.npm_config_myVar });

In CLI:

npm --myVar=something run-script cool

Should output:

{ myVar: 'something' }

Update: Using npm 3.10.3, it appears that it lowercases the process.env.npm_config_ variables? I'm also using better-npm-run, so I'm not sure if this is vanilla default behavior or not, but this answer is working. Instead of process.env.npm_config_myVar, try process.env.npm_config_myvar

Do you want an incrementing integer column returned with your recordset? If so: -

--Check for existance  
if  exists (select * from dbo.sysobjects where [id] = object_id(N'dbo.t') AND objectproperty(id, N'IsUserTable') = 1)  
drop table dbo.t
go

--create dummy table and insert data  
create table dbo.t(x char(1) not null primary key, y char(1) not null)  
go  
set nocount on  
insert dbo.t (x,y) values ('A','B')  
insert dbo.t (x,y) values ('C','D')  
insert dbo.t (x,y) values ('E','F')

--create temp table to add an identity column  
create table dbo.#TempWithIdentity(i int not null identity(1,1) primary key,x char(1) not null unique,y char(1) not null)  

--populate the temporary table  
insert into dbo.#TempWithIdentity(x,y) select x,y from dbo.t

--return the data  
select i,x,y from dbo.#TempWithIdentity

--clean up  
drop table dbo.#TempWithIdentity

Use ix operator:

print df.ix[159220]

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

You could say

 $name ne ""

instead of

 length $name > 0

Assuming you have two programs that process the two files, process_in.exe and process_out.exe:

for %%f in (*.in) do (
    echo %%~nf
    process_in "%%~nf.in"
    process_out "%%~nf.out"
)

%%~nf is a substitution modifier, that expands %f to a file name only. See other modifiers in https://technet.microsoft.com/en-us/library/bb490909.aspx (midway down the page) or just in the next answer.

After Pulling hair for a long time,I finally found an issue.I've selected wrong certificate while creating Provisioning Profile,By selecting right one,It helped for me.In your case,If it is multiple then You have to try and select one by one to get this issue solved.

?? TL;DR — One line solution.

All you have to do is:

sudo easy_install pip

2019: ??easy_install has been deprecated. Check Method #2 below for preferred installation!

I made a gif, coz. why not?

Details:

?? OK, I read the solutions given above, but here's an EASY solution to install pip.

MacOS comes with Python installed. But to make sure that you have Python installed open the terminal and run the following command.

python --version

If this command returns a version number that means Python exists. Which also means that you already have access to easy_install considering you are using macOS/OSX.

?? Now, all you have to do is run the following command.

sudo easy_install pip

After that, pip will be installed and you'll be able to use it for installing other packages.

Let me know if you have any problems installing pip this way.

Cheers!

P.S. I ended up blogging a post about it. QuickTip: How Do I Install pip on macOS or OS X?

? UPDATE (Jan 2019): METHOD #2: Two line solution —

easy_install has been deprecated. Please use get-pip.py instead.

First of all download the get-pip file

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Now run this file to install pip

python get-pip.py

That should do it.

Another gif you said? Here ya go!

Is this what you're after?

From the page on Random:

The method nextLong is implemented by class Random as if by:

public long nextLong() {
   return ((long)next(32) << 32) + next(32);
}

Because class Random uses a seed with only 48 bits, this algorithm will not return all possible long values.

So if you want to get a Long, you're already not going to get the full 64 bit range.

I would suggest that if you have a range that falls near a power of 2, you build up the Long as in that snippet, like this:

next(32) + ((long)nextInt(8) << 3)

to get a 35 bit range, for example.

When running python (cpython) on windows the <built-in function system> os.system will execute under the curtains _wsystem while if you're using a non-windows os, it'll use system.

On contrary, Popen should use CreateProcess on windows and _posixsubprocess.fork_exec in posix-based operating-systems.

That said, an important piece of advice comes from os.system docs, which says:

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.

There are several libraries. Here are two examples:

❐ Apache Commons Lang

Apache Commons Lang includes a special class to escape or unescape strings (CSV, EcmaScript, HTML, Java, Json, XML): org.apache.commons.lang3.StringEscapeUtils.

• Escape to CSV

  String escaped = StringEscapeUtils
      .escapeCsv("I said \"Hey, I am 5'10\".\""); // I said "Hey, I am 5'10"."
  
  System.out.println(escaped); // "I said ""Hey, I am 5'10""."""
  

• Unescape from CSV

  String unescaped = StringEscapeUtils
      .unescapeCsv("\"I said \"\"Hey, I am 5'10\"\".\"\"\""); // "I said ""Hey, I am 5'10""."""
  
  System.out.println(unescaped); // I said "Hey, I am 5'10"."
  

_{* You can download it from here.}

❐ OpenCSV

If you use OpenCSV, you will not need to worry about escape or unescape, only for write or read the content.

• Writing file:

  FileOutputStream fos = new FileOutputStream("awesomefile.csv"); 
  OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
  CSVWriter writer = new CSVWriter(osw);
  ...
  String[] row = {
      "123", 
      "John", 
      "Smith", 
      "39", 
      "I said \"Hey, I am 5'10\".\""
  };
  writer.writeNext(row);
  ...
  writer.close();
  osw.close();
  os.close();
  

• Reading file:

  FileInputStream fis = new FileInputStream("awesomefile.csv"); 
  InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
  CSVReader reader = new CSVReader(isr);
  
  for (String[] row; (row = reader.readNext()) != null;) {
      System.out.println(Arrays.toString(row));
  }
  
  reader.close();
  isr.close();
  fis.close();
  

_{* You can download it from here.}

var formData=new FormData();
formData.append("fieldname","value");
formData.append("image",$('[name="filename"]')[0].files[0]);

$.ajax({
    url:"page.php",
    data:formData,
    type: 'POST',
    dataType:"JSON",
    cache: false,
    contentType: false,
    processData: false,
    success:function(data){ }
});

You can use form data to post all your values including images.

For me, I was writing to a file that is opened in Excel.

Note: this will not work with ASP.Net Core because WebImage depends on System.Web, but on previous versions of ASP.Net I used this snippet many times and was useful.

String ThumbfullPath = Path.GetFileNameWithoutExtension(file.FileName) + "80x80.jpg";
var ThumbfullPath2 = Path.Combine(ThumbfullPath, fileThumb);
using (MemoryStream stream = new MemoryStream(System.IO.File.ReadAllBytes(fullPath)))
{
      var thumbnail = new WebImage(stream).Resize(80, 80);
      thumbnail.Save(ThumbfullPath2, "jpg");
}

If you are looking for a number that is bigger than all others:

Method 1:

float('inf')

Method 2:

import sys
max = sys.maxsize

If you are looking for a number that is smaller than all others:

Method 1:

float('-inf')

Method 2:

import sys
min = -sys.maxsize - 1

Method 1 works in both Python2 and Python3. Method 2 works in Python3. I have not tried Method 2 in Python2.

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

You will get:

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

Change the active scheme Device from Simulator to Generic iOS Device

Prefix the variable name with env:

$env:path

For example, if you want to print the value of environment value "MINISHIFT_USERNAME", then command will be:

$env:MINISHIFT_USERNAME

You can also enumerate all variables via the env drive:

Get-ChildItem env:

Your project has to have a builder set for it. If there is not one Eclipse will default to Ant. Which you can use you have to create an Ant build file, which you can Google how to do. It is rather involved though. This is not required to run locally in Eclipse though. If your class is run-able. It looks like yours is, but we can not see all of it.

If you look at your project build path do you have an output folder selected? If you check that folder have the compiled class files been put there? If not the something is not set in Eclpise for it to know to compile. You might check to see if auto build is set for your project.

The IIS inbound rules as shown in the question DO work. I had to clear the browser cache and add the following line in the top of my <head> section of the index.html page:

<base href="/myApplication/app/" />

This is because I have more than one application in localhost and so requests to other partials were being taken to localhost/app/view1 instead of localhost/myApplication/app/view1

Hopefully this helps someone!

Everyone is right: stick with POST for non-idempotent requests.

What about using both an URI query string and request content? Well it's valid HTTP (see note 1), so why not?!

It is also perfectly logical: URLs, including their query string part, are for locating resources. Whereas HTTP method verbs (POST - and its optional request content) are for specifying actions, or what to do with resources. Those should be orthogonal concerns. (But, they are not beautifully orthogonal concerns for the special case of ContentType=application/x-www-form-urlencoded, see note 2 below.)

Note 1: HTTP specification (1.1) does not state that query parameters and content are mutually exclusive for a HTTP server that accepts POST or PUT requests. So any server is free to accept both. I.e. if you write the server there's nothing to stop you choosing to accept both (except maybe an inflexible framework). Generally, the server can interpret query strings according to whatever rules it wants. It can even interpret them with conditional logic that refers to other headers like Content-Type too, which leads to Note 2:

Note 2: if a web browser is the primary way people are accessing your web application, and application/x-www-form-urlencoded is the Content-Type they are posting, then you should follow the rules for that Content-Type. And the rules for application/x-www-form-urlencoded are much more specific (and frankly, unusual): in this case you must interpret the URI as a set of parameters, and not a resource location. [This is the same point of usefulness Powerlord raised; that it may be hard to use web forms to POST content to your server. Just explained a little differently.]

Note 3: what are query strings originally for? RFC 3986 defines HTTP query strings as an URI part that works as a non-hierarchical way of locating a resource.

In case readers asking this question wish to ask what is good RESTful architecture: the RESTful architecture pattern doesn't require URI schemes to work a specific way. RESTful architecture concerns itself with other properties of the system, like cacheability of resources, the design of the resources themselves (their behavior, capabilities, and representations), and whether idempotence is satisfied. Or in other words, achieving a design which is highly compatible with HTTP protocol and its set of HTTP method verbs. :-) (In other words, RESTful architecture is not very presciptive with how the resources are located.)

Final note: sometimes query parameters get used for yet other things, which are neither locating resources nor encoding content. Ever seen a query parameter like 'PUT=true' or 'POST=true'? These are workarounds for browsers that don't allow you to use PUT and POST methods. While such parameters are seen as part of the URL query string (on the wire), I argue that they are not part of the URL's query in spirit.

Consider this situation: A sloppy API accepts GET requests like:

http://www.example.com/api?apikey=abcdef123456&action=deleteCategory&id=1

In some settings, when you request this URL and if there is an error/warning regarding the request, this whole line gets logged in the log file. Worse yet: if you forget to disable error messages in the production server, this information is just displayed in plain in the browser! Now you've just given your API key away to everyone.

Unfortunately, there are real API's working this way.

I wouldn't like the idea of having some sensitive info in the logs or displaying them in the browser. POST and GET is not the same. Use each where appropriate.

Have you looked at the samples provided with EPPlus?

This one shows you how to create a file http://epplus.codeplex.com/wikipage?title=ContentSheetExample

This one shows you how to use it to stream back a file http://epplus.codeplex.com/wikipage?title=WebapplicationExample

This is how we use the package to generate a file.

var newFile = new FileInfo(ExportFileName);
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{                       
    // do work here                            
    xlPackage.Save();
}

Sometimes you'll need to specify PATH and GEM_PATH using crontab with rvm.

Like this:

# top of crontab file
PATH=/home/user_name/.rvm/gems/ruby-2.2.0/bin:/home/user_name/.rvm/gems/ruby-2.2.0@global/bin:/home/user_name/.rvm/rubies/ruby-2.2.$
GEM_PATH=/home/user_name/.rvm/gems/ruby-2.2.0:/home/user_name/.rvm/gems/ruby-2.2.0@global

# jobs
00 00 * * * ruby path/to/your/script.rb
00 */4 * * * ruby path/to/your/script2.rb
00 8,12,22 * * * ruby path/to/your/script3.rb

The parent div (I assume the outermost div) is display: block and will fill up all available area of its container (in this case, the body) that it can. Use a different display type -- inline-block is probably what you are going for:

I have made this generic extension that I use.

public static class ObjectExtensions {
    public static void With<T>(this T value, Action<T> todo) {
        if (value != null) todo(value);
    }
}

Then I use it like below.

string myString = null;
myString.With((value) => Console.WriteLine(value)); // writes nothing
myString = "my value";
myString.With((value) => Console.WriteLine(value)); // Writes `my value`
