Programs & Examples On #Exitstatus

$ foo="/some/directory/file"
$ [ ${foo:0:1} == "/" ] && echo 1 || echo 0
1
$ foo="[email protected]:/some/directory/file"
$ [ ${foo:0:1} == "/" ] && echo 1 || echo 0
0

I've hacked up the following idiom:

echo "Generating from IDL..."
idlj -fclient -td java/src echo.idl
if [ $? -ne 0 ]; then { echo "Failed, aborting." ; exit 1; } fi

echo "Compiling classes..."
javac *java
if [ $? -ne 0 ]; then { echo "Failed, aborting." ; exit 1; } fi

echo "Done."

Precede each command with an informative echo, and follow each command with that same
if [ $? -ne 0 ];... line. (Of course, you can edit that error message if you want to.)

You can do this using the Event Kit framework in OS 4.0.

Right click on the FrameWorks group in the Groups and Files Navigator on the left of the window. Select 'Add' then 'Existing FrameWorks' then 'EventKit.Framework'.

Then you should be able to add events with code like this:

#import "EventTestViewController.h"
#import <EventKit/EventKit.h>

@implementation EventTestViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    EKEventStore *eventStore = [[EKEventStore alloc] init];

    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
    event.title     = @"EVENT TITLE";

    event.startDate = [[NSDate alloc] init];
    event.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];

    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
    NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];       
}

@end

this is just and slice of code, hope works for you

.init/.fini isn't deprecated. It's still part of the the ELF standard and I'd dare say it will be forever. Code in .init/.fini is run by the loader/runtime-linker when code is loaded/unloaded. I.e. on each ELF load (for example a shared library) code in .init will be run. It's still possible to use that mechanism to achieve about the same thing as with __attribute__((constructor))/((destructor)). It's old-school but it has some benefits.

.ctors/.dtors mechanism for example require support by system-rtl/loader/linker-script. This is far from certain to be available on all systems, for example deeply embedded systems where code executes on bare metal. I.e. even if __attribute__((constructor))/((destructor)) is supported by GCC, it's not certain it will run as it's up to the linker to organize it and to the loader (or in some cases, boot-code) to run it. To use .init/.fini instead, the easiest way is to use linker flags: -init & -fini (i.e. from GCC command line, syntax would be -Wl -init my_init -fini my_fini).

On system supporting both methods, one possible benefit is that code in .init is run before .ctors and code in .fini after .dtors. If order is relevant that's at least one crude but easy way to distinguish between init/exit functions.

A major drawback is that you can't easily have more than one _init and one _fini function per each loadable module and would probably have to fragment code in more .so than motivated. Another is that when using the linker method described above, one replaces the original _init and _fini default functions (provided by crti.o). This is where all sorts of initialization usually occur (on Linux this is where global variable assignment is initialized). A way around that is described here

Notice in the link above that a cascading to the original _init() is not needed as it's still in place. The call in the inline assembly however is x86-mnemonic and calling a function from assembly would look completely different for many other architectures (like ARM for example). I.e. code is not transparent.

.init/.fini and .ctors/.detors mechanisms are similar, but not quite. Code in .init/.fini runs "as is". I.e. you can have several functions in .init/.fini, but it is AFAIK syntactically difficult to put them there fully transparently in pure C without breaking up code in many small .so files.

.ctors/.dtors are differently organized than .init/.fini. .ctors/.dtors sections are both just tables with pointers to functions, and the "caller" is a system-provided loop that calls each function indirectly. I.e. the loop-caller can be architecture specific, but as it's part of the system (if it exists at all i.e.) it doesn't matter.

The following snippet adds new function pointers to the .ctors function array, principally the same way as __attribute__((constructor)) does (method can coexist with __attribute__((constructor))).

#define SECTION( S ) __attribute__ ((section ( S )))
void test(void) {
   printf("Hello\n");
}
void (*funcptr)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;

One can also add the function pointers to a completely different self-invented section. A modified linker script and an additional function mimicking the loader .ctors/.dtors loop is needed in such case. But with it one can achieve better control over execution order, add in-argument and return code handling e.t.a. (In a C++ project for example, it would be useful if in need of something running before or after global constructors).

I'd prefer __attribute__((constructor))/((destructor)) where possible, it's a simple and elegant solution even it feels like cheating. For bare-metal coders like myself, this is just not always an option.

Some good reference in the book Linkers & loaders.

Follow these steps:

1. Press Ctrl+H to bring up the Find/Replace Dialog.
2. Choose the Regular expression option near the bottom of the dialog.

To add a word, such as test, at the beginning of each line:

1. Type ^ in the Find what textbox
2. Type test in the Replace with textbox
3. Place cursor in the first line of the file to ensure all lines are affected
4. Click Replace All button

To add a word, such as test, at the end of each line:

1. Type $ in the Find what textbox
2. Type test in the Replace with textbox
3. Place cursor in the first line of the file to ensure all lines are affected
4. Click Replace All button

This will let Git authenticate on HTTPS using .netrc:

• The file should be named _netrc and located in c:\Users\<username>.
• You will need to set an environment variable called HOME=%USERPROFILE% (set system-wide environment variables using the System option in the control panel. Depending on the version of Windows, you may need to select "Advanced Options".).
• The password stored in the _netrc file cannot contain spaces (quoting the password will not work).

Yeah, Date object complects date and time, so comparing it with just date value does not work.

You can simply use the $where operator to express more complex condition with Javascript boolean expression :)

db.posts.find({ '$where': 'this.created_on.toJSON().slice(0, 10) == "2012-07-14"' })

created_on is the datetime field and 2012-07-14 is the specified date.

Date should be exactly in YYYY-MM-DD format.

Note: Use $where sparingly, it has performance implications.

Python is a very versatile language. You may print variables by different methods. I have listed below five methods. You may use them according to your convenience.

Example:

a = 1
b = 'ball'

Method 1:

print('I have %d %s' % (a, b))

Method 2:

print('I have', a, b)

Method 3:

print('I have {} {}'.format(a, b))

Method 4:

print('I have ' + str(a) + ' ' + b)

Method 5:

print(f'I have {a} {b}')

The output would be:

I have 1 ball

You should escape the JavaScript string delimiters inside the PHP string. You're using double quotes for both PHP and JavaScript strings. Try like this instead:

<html>
<body>
<?php

// Here, we use single quotes for PHP and double quotes for JavaScript
echo '<script type="text/javascript">';
echo 'document.write("Hello World!")';
echo '</script>';

?>
</body>
</html>

You have to escape quotes on both JavaScript and PHP when the string delimiter are the same as the quotes:

echo "\""; // escape is done using a backslash
echo '\'';

Same in JavaScript:

alert("\""); // escape is done using a backslash
alert(echo '\'');

But because it's very hard to read a string with such escape sequences, it is better to combine single with double quotes, as needed:

echo '"';
echo "'";

I still cannot make this work. Any other ideas?

to change pro-grammatically use :

imgview.setScaleType(ScaleType.FIT_XY);

OR

to change from xml use:

 android:scaleType="fitXY"

Solved the problem with:

I have the same issue, I'm not able to open a CSV file in Excel. I've found a solution that worked for me in this question Opening a file in excel via Workbooks.OpenText

That question helped me to figure out a code that works for me. The code looks more or less like this:

Private Sub OpenCSVFile(filename as String)
    Dim datasourceFilename As String
    Dim currentPath As String

    datasourceFilename = "\" & filename & ".csv"
    currentPath = ActiveWorkbook.Path

    Workbooks.OpenText Filename:=currentPath & datasourceFilename, _
                       Origin:=xlWindows, _
                       StartRow:=1, _
                       DataType:=xlDelimited, _
                       TextQualifier:=xlDoubleQuote, _
                       ConsecutiveDelimiter:=False, _
                       Tab:=False, _
                       Semicolon:=False, _
                       Comma:=True, _
                       Space:=False, _
                       Other:=False, _
                       FieldInfo:=Array(Array(1, 1), Array(2, 1)), _
                       DecimalSeparator:=".", _
                       ThousandsSeparator:=",", _
                       TrailingMinusNumbers:=True
End Sub

At least, it helped me to know about lots of parameters I can use with Workbooks.OpenText method.

simply you can use this

$("#chkAll").on("click",function(){
    $("input[name=checkBoxName]").prop("checked",$(this).prop("checked"));
});

If the text contains \r\n that need to be converted into new lines use the 'Extended' or 'Regular expression' modes and escape the backslash character in 'Find what':

Find what: \\r\\n

Replace with: \r\n

Replace @RestController with @Controller.

I've just solved this exact problem on my Ubuntu 14.04 with Eclipse Mars 2.

This could happen when Eclipse is not finding Tomcat's configuration files where they are expected to be. This place is in

$eclipse_workspace_folder/$version_of_your_tomcat_server_at_localhost/

(by default if you didn't changed server's name). So you have to copy all the files under your $tomcat_installation_folder/conf/* to the workspace server's folder.

But it was easier to just remove the server from your server list and add it again. Eclipse will automatically recreate all these files again into the proper folders. Like in the picture below:

In my case I've downloaded tomcat-8.0.35 from the website, so the configuration files needed are in /opt/apache-tomcat-8.0.35/conf/ filesystem.

Just delete the desired server from the Servers view (Window -> Show View -> Servers) and then go to Window -> Preferences -> Server -> Runtime Environment -> Add and add the server again.

Right click on the project

->Run As --> Run configurations.

Then select Maven Build

Then click new button to create a configuration of the selected type. Click on Browse workspace (now is Workspace...) then select your project and in goals specify eclipse:eclipse

Yes.

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

If you want the whole GitHub repository name ('full name') - user/repository, and you want to do it in with Ruby...

git remote show origin -n | ruby -ne 'puts /^\s*Fetch.*:(.*).git/.match($_)[1] rescue nil'

The sqlite answer is

update TABLE set mydatetime = datetime('now');

in case someone else was looking for it.

Override onDestroy of the Activity and Dismiss your Dialog & make it null

protected void onDestroy ()
    {
        if(mProgressDialog != null)
            if(mProgressDialog.isShowing())
                mProgressDialog.dismiss();
        mProgressDialog= null;
    }

In 2020, you can use the in-browser Crypto API to generate cryptographically strong random values.

function getRandomNumbers() {
  const typedArray = new Uint8Array(10);
  const randomValues = window.crypto.getRandomValues(typedArray);
  return randomValues.join('');
}

console.log(getRandomNumbers());
// 1857488137147725264738

both Uint8Array and Crypto.getRandomValues are supported on all major browsers, including IE11

The basic loop is not recommended as you do not know the implementation of the list.

If that was a LinkedList, each call to

list.get(i)

would be iterating over the list, resulting in N^2 time complexity.

myArrayOfMatrices = zeros(unknown,500,800);

If you're running out of memory throw more RAM in your system, and make sure you're running a 64 bit OS. Also try reducing your precision (do you really need doubles or can you get by with singles?):

myArrayOfMatrices = zeros(unknown,500,800,'single');

To append to that array try:

myArrayOfMatrices(unknown+1,:,:) = zeros(500,800);

you can use these styles:

style="border-left: 1px solid #cdd0d4;"  
style="border-bottom: 1px solid #cdd0d4;"
style="border-top: 1px solid #cdd0d4;"
style="border-right: 1px solid #cdd0d4;"

with this you want u must use

<td style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;">  

or

<img style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;"> 

Here a small example as response to the title as all mentioned examples are complicated in my opinion as well as the official one.

You should know how to transpile es2015 as well as make your server able to handle the redirect. Here is a snippet for express. More info related to this can be found here.

Make sure to put this below all other routes.

const app = express();
app.use(express.static('distApp'));

/**
 * Enable routing with React.
 */
app.get('*', (req, res) => {
  res.sendFile(path.resolve('distApp', 'index.html'));
});

This is the .jsx file. Notice how the longest path comes first and get's more general. For the most general routes use the exact attribute.

// Relative imports
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route, Switch, Redirect } from 'react-router-dom';

// Absolute imports
import YourReactComp from './YourReactComp.jsx';

const root = document.getElementById('root');

const MainPage= () => (
  <div>Main Page</div>
);

const EditPage= () => (
  <div>Edit Page</div>
);

const NoMatch = () => (
  <p>No Match</p>
);

const RoutedApp = () => (
  <BrowserRouter >
    <Switch>
      <Route path="/items/:id" component={EditPage} />
      <Route exact path="/items" component={MainPage} />          
      <Route path="/yourReactComp" component={YourReactComp} />
      <Route exact path="/" render={() => (<Redirect to="/items" />)} />          
      <Route path="*" component={NoMatch} />          
    </Switch>
  </BrowserRouter>
);

ReactDOM.render(<RoutedApp />, root); 

I did this plunker to explore one way to do what you want.

Here I get mystyle from the parent component but you can get it from a service.

import {Component, View} from 'angular2/angular2'

@Component({
  selector: '[my-person]',
  inputs: [
    'name',
    'mystyle: customstyle'
  ],
  host: {
    '[style.backgroundColor]': 'mystyle.backgroundColor'
  }
})
@View({
  template: `My Person Component: {{ name }}`
})
export class Person {}

By definining the following alias (in ~/.gitconfig) you can easily temporarily disable the fileMode per git command:

[alias]
nfm = "!f(){ git -c core.fileMode=false $@; };f"

When this alias is prefixed to the git command, the file mode changes won't show up with commands that would otherwise show them. For example:

git nfm status

use this..

@"(?></?\w+)(?>(?:[^>'""]+|'[^']*'|""[^""]*"")*)>"

You can use CSS3 transition

I had this same error in an MVC 4 application using Razor. In an attempt to clean up the web.config files, I removed the two webpages: configuration values:

<appSettings>
  <add key="webpages:Version" value="2.0.0.0" />
  <add key="webpages:Enabled" value="false" />

Once I restored these configuration values, the pages would compile correctly and the errors regarding the .Partial() extension method disappeared.

1. Select all the lines on which you want to add prefix or suffix. (But if you want to add prefix or suffix to only specific lines, you can use ctrl+Left mouse button to create multiple cursors.)
2. Push Ctrl+Shift+L.
3. Push Home key and add prefix.
4. Push End key and add suffix.

Note, disable wordwrap, otherwise it will not work properly if your lines are longer than sublime's width.

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col
Next

You can just split on the word boundary using \b. See MDN

"\b: Matches a zero-width word boundary, such as between a letter and a space."

You should also make sure it is followed by whitespace \s. so that strings like "My car isn't red" still work:

var stringArray = str.split(/\b(\s)/);

The initial \b is required to take multiple spaces into account, e.g. my car is red

EDIT: Added grouping

org.apache.commons.lang3.StringUtils.substring(s, -7) 

gives you the answer. It returns the input if it is shorter than 7, and null if s == null. It never throws an exception.

See https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#substring-java.lang.String-int-int-

To convert pdf to byteArray :

public byte[] pdfToByte(String filePath)throws JRException {

         File file = new File(<filePath>);
         FileInputStream fileInputStream;
         byte[] data = null;
         byte[] finalData = null;
         ByteArrayOutputStream byteArrayOutputStream = null;

         try {
            fileInputStream = new FileInputStream(file);
            data = new byte[(int)file.length()];
            finalData = new byte[(int)file.length()];
            byteArrayOutputStream = new ByteArrayOutputStream();

            fileInputStream.read(data);
            byteArrayOutputStream.write(data);
            finalData = byteArrayOutputStream.toByteArray();

            fileInputStream.close(); 

        } catch (FileNotFoundException e) {
            LOGGER.info("File not found" + e);
        } catch (IOException e) {
            LOGGER.info("IO exception" + e);
        }

        return finalData;

    }

You can do it like this:

SELECT * FROM ... WHERE name LIKE 'someone'

(It's not the solution, but in some cases is very convenient)

"The LIKE operator does a pattern matching comparison. The operand to the right contains the pattern, the left hand operand contains the string to match against the pattern. A percent symbol ("%") in the pattern matches any sequence of zero or more characters in the string. An underscore ("_") in the pattern matches any single character in the string. Any other character matches itself or its lower/upper case equivalent (i.e. case-insensitive matching). (A bug: SQLite only understands upper/lower case for ASCII characters. The LIKE operator is case sensitive for unicode characters that are beyond the ASCII range. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.)."

Move your branch pointer to the HEAD:

git branch -f master

Your branch master already exists, so git will not allow you to overwrite it, unless you use... -f (this argument stands for --force)

Or you can use rebase:

git rebase HEAD master

Do it on your own risk ;)

It works for me. Inject $window service in to your controller.

$window.open("somepath/", "_blank")

There are already a lot of good responses to this question, but I thought it may be helpful to clarify the case where you would expect the session cookie to be sent because the cookie domain matches, but it is not getting sent because the AJAX request is being made to a different subdomain. In this case, I have a cookie that is assigned to the *.mydomain.com domain, and I am wanting it to be included in an AJAX request to different.mydomain.com". By default, the cookie does not get sent. You do not need to disable HTTPONLY on the session cookie to resolve this issue. You only need to do what wombling suggested (https://stackoverflow.com/a/23660618/545223) and do the following.

1) Add the following to your ajax request.

xhrFields: { withCredentials:true }

2) Add the following to your response headers for resources in the different subdomain.

Access-Control-Allow-Origin : http://original.mydomain.com
Access-Control-Allow-Credentials : true

Remove the semi-colon after no-repeat, in the url and try it .

$("#globalsearchstr").focus(function(){
    $(this).parent().css("background", "url(/images/r-srchbg_white.png) no-repeat");
});

Inside controller inject Request object. So if you want to access request body inside controller method 'foo' do the following:

public function foo(Request $request){
    $bodyContent = $request->getContent();
}

I don't think you can set arbitrarily sized images on any of the existing button classes. If you want a simple image behaving like a button, you can write your own QAbstractButton-subclass, something like:

class ImageButton : public QAbstractButton {
Q_OBJECT
public:
...
    void setPixmap( const QPixmap& pm ) { m_pixmap = pm; update(); }
    QSize sizeHint() const { return m_pixmap.size(); }
protected:
    void paintEvent( QPaintEvent* e ) {
        QPainter p( this );
        p.drawPixmap( 0, 0, m_pixmap );
    }
};

1. Generalized Substring

To generalise the question and the answer of gniourf_gniourf (as this is what I was searching for), if you want to cut a range of characters from, say, 7th from the end to 3rd from the end, you can use this syntax:

${string: -7:4}

Where 4 is the length of course (7-3).

2. Alternative using cut

In addition, while the solution of gniourf_gniourf is obviously the best and neatest, I just wanted to add an alternative solution using cut:

echo $string | cut -c $((${#string}-2))-

Here, ${#string} is the length of the string, and the "-" means cut to the end.

3. Alternative using awk

This solution instead uses the substring function of awk to select a substring which has the syntax substr(string, start, length) going to the end if the length is omitted. length($string)-2) thus picks up the last three characters.

echo $string | awk '{print substr($1,length($1)-2) }'

Try this one

DATE_ADD(datefield, INTERVAL 30 MINUTE)

Or no float conversion at all by just specifying floats in the list.

l = [-1.2, 0.0, 1]
x = min(l)

or

l = min([-1.2, 0.0, 1])

Use a ByteArrayOutputStream. Here is the process:

• Get an InputStream to read data
• Create a ByteArrayOutputStream.
• Copy all the InputStream into the OutputStream
• Get your byte[] from the ByteArrayOutputStream using the toByteArray() method

Made a modification to the solutions, so it will work with multiple divs based on class instead of specific IDs. For example, if you have multiple blocks of code. This assumes that the div class is set to "code".

<script>
        $( document ).ready(function() {
            $(".code").click(function(event){
                var range = document.createRange();
                range.selectNode(this);
                window.getSelection().removeAllRanges(); // clear current selection
                window.getSelection().addRange(range); // to select text
                document.execCommand("copy");
                window.getSelection().removeAllRanges();// to deselect
            });
        });
    </script>

I think using window.devicePixelRatio is more elegant than the window.matchMedia solution:

if (window.innerWidth*window.devicePixelRatio <= 960 
    && window.innerHeight*window.devicePixelRatio <= 640) { 
    ... 
}

For null values in the dataframe of pyspark

Dict_Null = {col:df.filter(df[col].isNull()).count() for col in df.columns}
Dict_Null

# The output in dict where key is column name and value is null values in that column

{'#': 0,
 'Name': 0,
 'Type 1': 0,
 'Type 2': 386,
 'Total': 0,
 'HP': 0,
 'Attack': 0,
 'Defense': 0,
 'Sp_Atk': 0,
 'Sp_Def': 0,
 'Speed': 0,
 'Generation': 0,

Lists of bytes are subscriptable (at least in Python 3.6). This way you can retrieve the decimal value of each byte individually.

>>> intlist = [64, 4, 26, 163, 255]
>>> bytelist = bytes(intlist)       # b'@x04\x1a\xa3\xff'

>>> for b in bytelist:
...    print(b)                     # 64  4  26  163  255

>>> [b for b in bytelist]           # [64, 4, 26, 163, 255]

>>> bytelist[2]                     # 26 

this might work , you can use the comment out code as well that also woks well with the given scenerio.

In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.

Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts

There is also a builtin function execfile(filename) that will do what you want

If there really is need for something faster than reflection, and it's not just a premature optimization, then bytecode generation with ASM or a higher level library is an option. Generating the bytecode the first time is slower than just using reflection, but once the bytecode has been generated, it is as fast as normal Java code and will be optimized by the JIT compiler.

Some examples of applications which use code generation:

• Invoking methods on proxies generated by CGLIB is slightly faster than Java's dynamic proxies, because CGLIB generates bytecode for its proxies, but dynamic proxies use only reflection (I measured CGLIB to be about 10x faster in method calls, but creating the proxies was slower).

• JSerial generates bytecode for reading/writing the fields of serialized objects, instead of using reflection. There are some benchmarks on JSerial's site.

• I'm not 100% sure (and I don't feel like reading the source now), but I think Guice generates bytecode to do dependency injection. Correct me if I'm wrong.

You will be able to get the time using below query:

select left((convert(time(0), GETDATE ())),5)

Add a contextmenu to your form and then assign it in the control's properties under ContextMenuStrip. Hope this helps :).

Hope this helps:

ContextMenu cm = new ContextMenu();
cm.MenuItems.Add("Item 1");
cm.MenuItems.Add("Item 2");

pictureBox1.ContextMenu = cm;

My use case is similar, except that I want a log cleanup event to run at 2am every night. As I said in the comment above, the DAY_HOUR doesn't work for me. In my case I don't really mind potentially missing the first day (and, given it is to run at 2am then 2am tomorrow is almost always the next 2am) so I use:

CREATE EVENT applog_clean_event
ON SCHEDULE 
    EVERY 1 DAY
    STARTS str_to_date( date_format(now(), '%Y%m%d 0200'), '%Y%m%d %H%i' ) + INTERVAL 1 DAY

                                }
                            });

                            $this.h2cDone = true;

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

1. Create a UNIQUE constraint on your subs_email column, if one does not already exist:

   ALTER TABLE subs ADD UNIQUE (subs_email)
   

2. Use INSERT ... ON DUPLICATE KEY UPDATE:

   INSERT INTO subs
     (subs_name, subs_email, subs_birthday)
   VALUES
     (?, ?, ?)
   ON DUPLICATE KEY UPDATE
     subs_name     = VALUES(subs_name),
     subs_birthday = VALUES(subs_birthday)
   

You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com

3. Note that I have used parameter placeholders in the place of string literals, as one really should be using parameterised statements to defend against SQL injection attacks.

Add this code on values anim

In case you want to work with the original MNIST files, here is how you can deserialize them.

If you haven't downloaded the files yet, do that first by running the following in the terminal:

wget http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz

Then save the following as deserialize.py and run it.

import numpy as np
import gzip

IMG_DIM = 28

def decode_image_file(fname):
    result = []
    n_bytes_per_img = IMG_DIM*IMG_DIM

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[16:]

        if len(data) % n_bytes_per_img != 0:
            raise Exception('Something wrong with the file')

        result = np.frombuffer(data, dtype=np.uint8).reshape(
            len(bytes_)//n_bytes_per_img, n_bytes_per_img)

    return result

def decode_label_file(fname):
    result = []

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[8:]

        result = np.frombuffer(data, dtype=np.uint8)

    return result

train_images = decode_image_file('train-images-idx3-ubyte.gz')
train_labels = decode_label_file('train-labels-idx1-ubyte.gz')

test_images = decode_image_file('t10k-images-idx3-ubyte.gz')
test_labels = decode_label_file('t10k-labels-idx1-ubyte.gz')

The script doesn't normalize the pixel values like in the pickled file. To do that, all you have to do is

train_images = train_images/255
test_images = test_images/255

You separate the values you want to return by commas:

def get_name():
   # you code
   return first_name, last_name

The commas indicate it's a tuple, so you could wrap your values by parentheses:

return (first_name, last_name)

Then when you call the function you a) save all values to one variable as a tuple, or b) separate your variable names by commas

name = get_name() # this is a tuple
first_name, last_name = get_name()
(first_name, last_name) = get_name() # You can put parentheses, but I find it ugly

string time = "19851231";
DateTime theTime= DateTime.ParseExact(time,
                                        "yyyyMMdd",
                                        CultureInfo.InvariantCulture,
                                        DateTimeStyles.None);

After reading the answers above I wrote a Q&D shell script (should work on sh and bash) to run g++ on PGM.cpp to produce executable image PGM. It assumes that the last argument on the command line is the file name (.cpp is optional) and all other arguments are options.

#!/bin/sh
if [ $# -lt 1 ]
then
    echo "Usage: `basename $0` [opt] pgm runs g++ to compile pgm[.cpp] into pgm"
    exit 2
fi
OPT=
PGM=
# PGM is the last argument, all others are considered options
for F; do OPT="$OPT $PGM"; PGM=$F; done
DIR=`dirname $PGM`
PGM=`basename $PGM .cpp`
# put -o first so it can be overridden by -o specified in OPT
set -x
g++ -o $DIR/$PGM $OPT $DIR/$PGM.cpp

You can't break from a forEach. I can think of three ways to fake it, though.

1. The Ugly Way: pass a second argument to forEach to use as context, and store a boolean in there, then use an if. This looks awful.

2. The Controversial Way: surround the whole thing in a try-catch block and throw an exception when you want to break. This looks pretty bad and may affect performance, but can be encapsulated.

3. The Fun Way: use every().

['a', 'b', 'c'].every(function(element, index) {
  // Do your thing, then:
  if (you_want_to_break) return false
  else return true
})

You can use some() instead, if you'd rather return true to break.

For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this

 dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha4'   
          ....
    }

then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program

i use (and recommend):

$(document).attr("title", "Another Title");

and it works in IE as well this is an alias to

document.title = "Another Title";

Some will debate on wich is better, prop or attr, and since prop call DOM properties and attr Call HTML properties, i think this is actually better...

use this after the DOM Load

$(function(){
    $(document).attr("title", "Another Title");
});

hope this helps.

The only reason that the linter complains about using setState({..}) in componentDidMount and componentDidUpdate is that when the component render the setState immediately causes the component to re-render. But the most important thing to note: using it inside these component's lifecycles is not an anti-pattern in React.

Please take a look at this issue. you will understand more about this topic. Thanks for reading my answer.

In other words, doesn't DEFAULT render NOT NULL redundant ?

No, it is not redundant. To extended accepted answer. For column col which is nullable awe can insert NULL even when DEFAULT is defined:

CREATE TABLE t(id INT PRIMARY KEY, col INT DEFAULT 10);

-- we just inserted NULL into column with DEFAULT
INSERT INTO t(id, col) VALUES(1, NULL);

+-----+------+
| ID  | COL  |
+-----+------+
|   1 | null |
+-----+------+

Oracle introduced additional syntax for such scenario to overide explicit NULL with default DEFAULT ON NULL:

CREATE TABLE t2(id INT PRIMARY KEY, col INT DEFAULT ON NULL 10);
-- same as
--CREATE TABLE t2(id INT PRIMARY KEY, col INT DEFAULT ON NULL 10 NOT NULL); 

INSERT INTO t2(id, col) VALUES(1, NULL);

+-----+-----+
| ID  | COL |
+-----+-----+
|  1  |  10 |
+-----+-----+

Here we tried to insert NULL but get default instead.

db<>fiddle demo

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified.

What you also should consider, is keeping a reference to the created element, then you can easily remove it specificly:

   var newUL = $('<ul><li>test</li></ul>');
   $(this).append(newUL);

   // Later ...

   newUL.remove();

Your code sample didn't expand on part of your topic, namely symbols, and so that part of the question went unanswered.

If you have two strings, foo and bar, and both can be either a string or a symbol, you can test equality with

foo.to_s == bar.to_s

It's a little more efficient to skip the string conversions on operands with known type. So if foo is always a string

foo == bar.to_s

But the efficiency gain is almost certainly not worth demanding any extra work on behalf of the caller.

Prior to Ruby 2.2, avoid interning uncontrolled input strings for the purpose of comparison (with strings or symbols), because symbols are not garbage collected, and so you can open yourself to denial of service through resource exhaustion. Limit your use of symbols to values you control, i.e. literals in your code, and trusted configuration properties.

Ruby 2.2 introduced garbage collection of symbols.

Python 2.X

dict((k, v) for k, v in metadata.iteritems() if v)

Python 2.7 - 3.X

{k: v for k, v in metadata.items() if v is not None}

Note that all of your keys have values. It's just that some of those values are the empty string. There's no such thing as a key in a dict without a value; if it didn't have a value, it wouldn't be in the dict.

INTEGER

if echo "$var" | egrep -q '^\-?[0-9]+$'; then 
    echo "$var is an integer"
else 
    echo "$var is not an integer"
fi

tests (with var=2 etc.):

2 is an integer
-2 is an integer
2.5 is not an integer 
2b is not an integer

NUMBER

if echo "$var" | egrep -q '^\-?[0-9]*\.?[0-9]+$'; then 
    echo "$var is a number"
else 
    echo "$var is not a number"
fi

tests (with var=2 etc.):

2 is a number
-2 is a number
-2.6 is a number
-2.c6 is not a number
2. is not a number
2.0 is a number

Further to aduchis answer above - if you then need to filter based on those group by keys, you can define a class to wrap the many keys.

return customers.GroupBy(a => new CustomerGroupingKey(a.Country, a.Gender))
                .Where(a => a.Key.Country == "Ireland" && a.Key.Gender == "M")
                .SelectMany(a => a)
                .ToList();

Where CustomerGroupingKey takes the group keys:

    private class CustomerGroupingKey
    {
        public CustomerGroupingKey(string country, string gender)
        {
            Country = country;
            Gender = gender;
        }

        public string Country { get; }

        public string Gender { get; }
    }

To support a better understanding of copying of objects, this illustrative jsbin may be of value

After set listen_addresses = '*' in postgresql.conf

Edit the pg_hba.conf file and add the following entry at the very end of file:

host    all             all              0.0.0.0/0                       md5
host    all             all              ::/0                            md5

For finding the config files this link might help you.

Intellisense is not auto refreshed and you should not fully rely on that

Others have pointed to the general problem (and are valid answers), but I'll just offer one additional comment: it's not that you should NEVER do it, but rather that do it as little as possible.

Usually this means that it is done exactly once: during bootstrapping. And then it's just to access the "root" bean, through which other dependencies can be resolved. This can be reusable code, like base servlet (if developing web apps).

You can use like this...

<div id="rot">hello</div>

#rot
{
   -webkit-transform: rotate(-90deg); 
   -moz-transform: rotate(-90deg);    
    width:100px;
}

Have a look at this fiddle:http://jsfiddle.net/anish/MAN4g/

The combination that worked for me was:

1. Copy the dSYM file into the directory where the crash report was
2. Unzip the ipa file containing the app ('unzip MyApp.ipa')
3. Copy the application binary from the resulting exploded payload into the same folder as the crash report and symbol file (Something like "MyApp.app/MyApp")
4. Import or Re-symbolicate the crash report from within Xcode's organizer

Using atos I wasn't able to resolve the correct symbol information with the addresses and offsets that were in the crash report. When I did this, I see something more meaningful, and it seems to be a legitimate stack trace.

You can just set it to a class variable and read it from the main program:

class Foo:
    def __init__(self):
        #Do your stuff here
        self.returncode = 42
bar = Foo()
baz = bar.returncode

I found a not-very-intuitive way to do this by using DUMP()

SELECT DUMP(A.NAME), 
       DUMP(A.surname), 
       DUMP(B.ordernum) 
FROM   customer A 
       JOIN orders B 
         ON A.id = B.id

It will return something like:

'Typ=1 Len=2: 0,48' for each column.

Type=1 means VARCHAR2/NVARCHAR2
Type=2 means NUMBER/FLOAT
Type=12 means DATE, etc.

You can refer to this oracle doc for information Datatype Code
or this for a simple mapping Oracle Type Code Mappings

Both answers are correct. If you user .TO -method then the semicolumn is OK - but not for the addrecipients-method. There you need to split, e.g. :

                Dim Splitter() As String
                Splitter = Split(AddrMail, ";")
                For Each Dest In Splitter
                    .Recipients.Add (Trim(Dest))
                Next

There's no way to allocate the whole thing in one go. Instead, create an array of pointers, then, for each pointer, create the memory for it. For example:

int** array;
array = (int**)malloc(sizeof(int*) * 50);
for(int i = 0; i < 50; i++)
    array[i] = (int*)malloc(sizeof(int) * 50);

Of course, you can also declare the array as int* array[50] and skip the first malloc, but the second set is needed in order to dynamically allocate the required storage.

It is possible to hack a way to allocate it in a single step, but it would require a custom lookup function, but writing that in such a way that it will always work can be annoying. An example could be L(arr,x,y,max_x) arr[(y)*(max_x) + (x)], then malloc a block of 50*50 ints or whatever and access using that L macro, e.g.

#define L(arr,x,y,max_x) arr[(y)*(max_x) + (x)]

int dim_x = 50;
int dim_y = 50;

int* array = malloc(dim_x*dim_y*sizeof(int));

int foo = L(array, 4, 6, dim_x);

But that's much nastier unless you know the effects of what you're doing with the preprocessor macro.

request.referer is set by Rack and is set as follows:

def referer
  @env['HTTP_REFERER'] || '/'
end

Just do a redirect_to request.referer and it will always redirect to the true referring page, or the root_path ('/'). This is essential when passing tests that fail in cases of direct-nav to a particular page in which the controller throws a redirect_to :back

EDIT: This function only swaps the endianness of aligned 16 bit words. A function often necessary for UTF-16/UCS-2 encodings. EDIT END.

If you want to change the endianess of a memory block you can use my blazingly fast approach. Your memory array should have a size that is a multiple of 8.

#include <stddef.h>
#include <limits.h>
#include <stdint.h>

void ChangeMemEndianness(uint64_t *mem, size_t size) 
{
uint64_t m1 = 0xFF00FF00FF00FF00ULL, m2 = m1 >> CHAR_BIT;

size = (size + (sizeof (uint64_t) - 1)) / sizeof (uint64_t);
for(; size; size--, mem++)
  *mem = ((*mem & m1) >> CHAR_BIT) | ((*mem & m2) << CHAR_BIT);
}

This kind of function is useful for changing the endianess of Unicode UCS-2/UTF-16 files.

It's March 2019, and I just did it this way:

1. Access https://id.atlassian.com/login/resetpassword
2. Fill your email and click "Send recovery link"
3. You will receive an email, and this is where people mess it up. Don't click the Log in to my account button, instead, you want to click the small link bellow that says Alternatively, you can reset your password for your Atlassian account.
4. Set a password as you normally would

Now try to run git commands on terminal.

It might ask you to do a two-step verification the first time, just follow the steps and you're done!

Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.

The Max value of the default Int in Python 2 is 65535, anything above that will be a long

For example:

>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>

In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.

For example:

• 32 bit systems the default datatype for integers will be 'Int32'
• 64 bit systems the default datatype for integers will be 'Int64'

The min/max values of each type can be found below:

• Int8: [-128,127]
• Int16: [-32768,32767]
• Int32: [-2147483648,2147483647]
• Int64: [-9223372036854775808,9223372036854775807]
• Int128: [-170141183460469231731687303715884105728,170141183460469231731687303715884105727]
• UInt8: [0,255]
• UInt16: [0,65535]
• UInt32: [0,4294967295]
• UInt64: [0,18446744073709551615]
• UInt128: [0,340282366920938463463374607431768211455]

If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.

Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.

There are different ways to check the size of the int and it's memory allocation. Note: In Python 3, using the built-in type() method will always return <class 'int'> no matter what size Int you are using.

Using a filter works for me in C#.

string s = "searchTerm";
    var filter = Builders<Model>.Filter.Where(p => p.Title.ToLower().Contains(s.ToLower()));
                var listSorted = collection.Find(filter).ToList();
                var list = collection.Find(filter).ToList();

It may even use the index because I believe the methods are called after the return happens but I haven't tested this out yet.

This also avoids a problem of

var filter = Builders<Model>.Filter.Eq(p => p.Title.ToLower(), s.ToLower());

that mongodb will think p.Title.ToLower() is a property and won't map properly.

You can use FindIndex

 var index = Array.FindIndex(myArray, row => row.Author == "xyz");

Edit: I see you have an array of string, you can use any code to match, here an example with a simple contains:

 var index = Array.FindIndex(myArray, row => row.Contains("Author='xyz'"));

Maybe you need to match using a regular expression?

Apache Commons has an IntegerValidator class which appears to do what you want. Java provides no in-built method for doing this.

See here for the groupid/artifactid.

You should use the background attribute to give an image to that element, and I would use ::after instead of before, this way it should be already drawn on top of your element.

.Modal:before{
  content: '';
  background:url('blackCarrot.png');
  width: /* width of the image */;
  height: /* height of the image */;
  display: block;
}

A simple and straightforward solution:

Use a standard for-loop running backwards on your collection and RemoveAt(i) to remove elements.

>>> import datetime
>>> first_time = datetime.datetime.now()
>>> later_time = datetime.datetime.now()
>>> difference = later_time - first_time
>>> seconds_in_day = 24 * 60 * 60
datetime.timedelta(0, 8, 562000)
>>> divmod(difference.days * seconds_in_day + difference.seconds, 60)
(0, 8)      # 0 minutes, 8 seconds

Subtracting the later time from the first time difference = later_time - first_time creates a datetime object that only holds the difference. In the example above it is 0 minutes, 8 seconds and 562000 microseconds.

This worked well for me.

Button Style

<Style x:Key="TransparentStyle" TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Border>
                    <Border.Style>
                        <Style TargetType="{x:Type Border}">
                            <Style.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter Property="Background" Value="DarkGoldenrod"/>
                                </Trigger>
                            </Style.Triggers>
                        </Style>
                    </Border.Style>
                    <Grid Background="Transparent">
                        <ContentPresenter></ContentPresenter>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Button

<Button Style="{StaticResource TransparentStyle}" VerticalAlignment="Top" HorizontalAlignment="Right" Width="25" Height="25"
        Command="{Binding CloseWindow}">
    <Button.Content >
        <Grid Margin="0 0 0 0">
            <Path Data="M0,7 L10,17 M0,17 L10,7" Stroke="Blue" StrokeThickness="2" HorizontalAlignment="Center" Stretch="None" />
        </Grid>
    </Button.Content>
</Button>

Notes

• The button displays a little blue cross, much like the one used to close a window.
• By setting the background of the grid to "Transparent", it adds a hittest, which means that if the mouse is anywhere over the button, then it will work. Omit this tag, and the button will only light up if the mouse is over one of the vector lines in the icon (this is not very usable).

As stated in a similar question, try removing instances of the input-group class and see if that helps.

refering to bootstrap:

Individual form controls automatically receive some global styling. All textual , , and elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

To mark a lambda async, simply prepend async before its argument list:

// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
    SQLiteUtils slu = new SQLiteUtils();
    await slu.DeleteGroupAsync(groupName);
}));

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

I realize this is late, but there is another way to obtain the URL of the profile image.

To your original url, you can add the parameter redirect=false to obtain the actual URL of the image you'd normally be redirected to.

So, the new request would look like http://graph.facebook.com/517267866/picture?type=large&redirect=false. This will return a JSON object containing the URL of the picture and a boolean is_silhouette (true if the picture is the default Facebook picture).

The picture will be of the size you specified, as well. You can test this additionally by adding dimensions: http://graph.facebook.com/517267866/picture?type=large&redirect=false&width=400&height=400

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

Here is a simple threading example for Android. It's very basic but it should help you to get a perspective.

Android code - Main.java

package test12.tt;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class Test12Activity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final TextView txt1 = (TextView) findViewById(R.id.sm);

        new Thread(new Runnable() { 
            public void run(){        
            txt1.setText("Thread!!");
            }
        }).start();

    }    
}

Android application xml - main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView  
    android:id = "@+id/sm"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"/>

</LinearLayout>

For Facebook share with an image without an API and using a # to deep link into a sub page, the trick was to share the image as picture=

The variable mainUrl would be http://yoururl.com/

var d1 = $('.targ .t1').text();
var d2 = $('.targ .t2').text();
var d3 = $('.targ .t3').text();
var d4 = $('.targ .t4').text();
var descript_ = d1 + ' ' + d2 + ' ' + d3 + ' ' + d4;
var descript = encodeURIComponent(descript_);

var imgUrl_ = 'path/to/mypic_'+id+'.jpg';
var imgUrl = mainUrl + encodeURIComponent(imgUrl_);

var shareLink = mainUrl + encodeURIComponent('mypage.html#' + id);

var fbShareLink = shareLink + '&picture=' + imgUrl + '&description=' + descript;
var twShareLink = 'text=' + descript + '&url=' + shareLink;

// facebook
$(".my-btn .facebook").off("tap click").on("tap click",function(){
  var fbpopup = window.open("https://www.facebook.com/sharer/sharer.php?u=" + fbShareLink, "pop", "width=600, height=400, scrollbars=no");
  return false;
});

// twitter
$(".my-btn .twitter").off("tap click").on("tap click",function(){
  var twpopup = window.open("http://twitter.com/intent/tweet?" + twShareLink , "pop", "width=600, height=400, scrollbars=no");
  return false;
});

The shortest version I found is to use the --cat option of parallel like below. This version avoids using xargs, only relying on features of parallel:

cat files.txt | \
  parallel -n 500 --lb --pipe --cat rsync --files-from={} user@remote:/dir /dir -avPi

#### Arg explainer
# -n 500           :: split input into chunks of 500 entries
#
# --cat            :: create a tmp file referenced by {} containing the 500 
#                     entry content for each process
#
# user@remote:/dir :: the root relative to which entries in files.txt are considered
#
# /dir             :: local root relative to which files are copied

Sample content from files.txt:

/dir/file-1
/dir/subdir/file-2
....

Note that this doesn't use -j 50 for job count, that didn't work on my end here. Instead I've used -n 500 for record count per job, calculated as a reasonable number given the total number of records.

If you don't want to depends on window title use this :

    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

...

    IntPtr h = Process.GetCurrentProcess().MainWindowHandle;
    ShowWindow(h, 0);
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new FormPrincipale());

UPDATE YourTable SET columnName = null WHERE YourCondition

Daniel Kutik's answer is correct, but it can be even more safe, with database renaming.

So, the truly safe way is:

1. Create new database with the different encoding and name
2. Dump your database
3. Restore dump to the new DB
4. Test that your application runs correctly with the new DB
5. Rename old DB to something meaningful
6. Rename new DB
7. Test application again
8. Drop the old database

In case of emergency, just rename DBs back

Use tail command:

ls -t | tail -n 5

JPA will use all properties of the class, unless you specifically mark them with @Transient:

@Transient
private String agencyName;

The @Column annotation is purely optional, and is there to let you override the auto-generated column name. Furthermore, the length attribute of @Column is only used when auto-generating table definitions, it has no effect on the runtime.

<br> is an HTML element. There isn't any ASCII code for it.

But, for line break sometimes 
 is used as the text code.

Or <br>

You can check the text code here.

You can pass image in short without using bundle like this This is the code of sender .class file

Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher;
Intent intent = new Intent();
Intent.setClass(<Sender_Activity>.this, <Receiver_Activity.class);
Intent.putExtra("Bitmap", bitmap);
startActivity(intent);

and this is receiver class file code.

Bitmap bitmap = (Bitmap)this.getIntent().getParcelableExtra("Bitmap");
ImageView viewBitmap = (ImageView)findViewById(R.id.bitmapview);
viewBitmap.setImageBitmap(bitmap);

No need to compress. that's it

Simply move the declaration outside of the if block.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store2_logo.gif";
    }
}

<a href="@Url.RouteUrl("HomePage")" class="logo"><img  alt="" src="@imgsrc"></a>

You could make it a bit cleaner.

@{
string currentstore=HttpContext.Current.Request.ServerVariables["HTTP_HOST"];
string imgsrc="/content/images/uploaded/store2_logo.gif";
if (currentstore == "www.mydomain.com")
    {
    <link href="/path/to/my/stylesheets/styles1-print.css" rel="stylesheet" type="text/css" />
    imgsrc="/content/images/uploaded/store1_logo.jpg";
    }
else
    {
    <link href="/path/to/my/stylesheets/styles2-print.css" rel="stylesheet" type="text/css" />
    }
}

As other have alluded, 7-zip is great.

Note: I am going to zip and then unzip a file. Unzip is at the bottom.

My contribution:

Get the

7-Zip Command Line Version

Current URL

http://www.7-zip.org/download.html

The syntax?

You can put the following into a .bat file

"C:\Program Files\7-Zip\7z.exe" a MySuperCoolZipFile.zip "C:\MyFiles\*.jpg" -pmypassword -r -w"C:\MyFiles\" -mem=AES256

I've shown a few options.

-r is recursive. Usually what you want with zip functionality.

a is for "archive". That's the name of the output zip file.

-p is for a password (optional)

-w is a the source directory. This will nest your files correctly in the zip file, without extra folder information.

-mem is the encryption strength.

There are others. But the above will get you running.

NOTE: Adding a password will make the zip file unfriendly when it comes to viewing the file through Windows Explorer. The client may need their own copy of 7-zip (or winzip or other) to view the contents of the file.

EDIT::::::::::::(just extra stuff).

There is a "command line" version which is probably better suited for this: http://www.7-zip.org/download.html

(current (at time of writing) direct link) http://sourceforge.net/projects/sevenzip/files/7-Zip/9.20/7za920.zip/download

So the zip command would be (with the command line version of the 7 zip tool).

"C:\WhereIUnzippedCommandLineStuff\7za.exe" a MySuperCoolZipFile.zip "C:\MyFiles\*.jpg" -pmypassword -r -w"C:\MyFiles\" -mem=AES256

Now the unzip portion: (to unzip the file you just created)

"C:\WhereIUnzippedCommandLineStuff\7zipCommandLine\7za.exe" e MySuperCoolZipFile.zip "*.*" -oC:\SomeOtherFolder\MyUnzippedFolder -pmypassword -y -r

As an alternative to the "e" argument, there is a x argument.

  e: Extract files from archive (without using directory names)
  x: eXtract files with full paths

Documentation here:

http://sevenzip.sourceforge.jp/chm/cmdline/commands/extract.htm

How about something like this?

<div id="leftContainer">
  <span>Company Name</span>
  <br><input type="text" value="John Lewis Partnership">
</div>
<div id="rightContainer">
  <span>Contact Name</span>
  <br><input type="text" value="Timothy Patten">
</div>

Then, you can align the 2 divs by floating them left and right:-

#leftContainer {
   float:left;
}

#rightContainer {
   float:right;
}

Doesn't the Directory.GetFiles(String, String) overload already do that? You would just do Directory.GetFiles(dir, "*.jpg", SearchOption.AllDirectories)

If you want to put them in a list, then just replace the "*.jpg" with a variable that iterates over a list and aggregate the results into an overall result set. Much clearer than individually specifying them. =)

Something like...

foreach(String fileExtension in extensionList){
    foreach(String file in Directory.GetFiles(dir, fileExtension, SearchOption.AllDirectories)){
        allFiles.Add(file);
    }
}

(If your directories are large, using EnumerateFiles instead of GetFiles can potentially be more efficient)

You can use library "fluttertoast". To do this, add it in pubspec.yaml file like:

dependencies:
  fluttertoast: ^3.1.0

Then import that library in the dart file you need the toast and write your code. For example, refer to the following code:

import 'package:flutter/material.dart';
import 'package:fluttertoast/fluttertoast.dart';



class ToastExample extends StatefulWidget {
    @override
    _ToastExampleState createState() {
      return _ToastExampleState();
    }
  }

  class _ToastExampleState extends State {
    void showToast() {
      Fluttertoast.showToast(
          msg: 'Some text',
          toastLength: Toast.LENGTH_SHORT,
          gravity: ToastGravity.CENTER,
          timeInSecForIos: 1,
          backgroundColor: Colors.red,
          textColor: Colors.white
      );
    }

    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        title: 'Toast Tutorial',
        home: Scaffold(
            appBar: AppBar(
              title: Text('Toast Tutorial'),
            ),
            body: Padding(
              padding: EdgeInsets.all(15.0),
              child: Center(
                child: RaisedButton(
                  child: Text('Press to show'),
                  onPressed: showToast,
                ),
              ),
            )
        ),
      );
    }
  }

  void main() => runApp(ToastExample());

public void OnClick(View.v)
Button b1 = (Button) findViewById(R.id.playButton);
b1.setVisiblity(View.INVISIBLE);

Just for completeness, this also works

from IPython.core.pylabtools import figsize
figsize(14, 7)

It is a wrapper aroung the rcParams solution

If the .project and .classpath are already committed, then they need to be removed from the index (but not the disk)

git rm --cached .project
git rm --cached .classpath

Then the .gitignore would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse file will then work, which does include:

# Eclipse Core      
.project

# JDT-specific (Eclipse Java Development Tools)     
.classpath

Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR set to a shared folder accessible by all).
That template folder can contain an info/exclude file, with ignore rules that you want enforced for all repos, including the new ones (git init) that any user would use.

As commented by Abdollah

When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files .classpath and .project from the repo.

You can do it using jQuery. Example:

<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>

<script>
    $.ajax({
        url : "next.php",
        type: "POST",
        data : "name=Denniss",
        success: function(data)
        {
            //data - response from server
            $('#response_div').html(data);
        }
    });
</script>

pyinstaller --clean --onefile --icon=default.ico Registry.py

It works for Me

Combining @Ramnath and @Tommy's answers allowed me to find an approach that works in base R for one or more columns.

Basic usage:

> df = data.frame(
+   id=1:3, foo=c('a|b','b|c','c|d'), 
+   bar=c('p|q', 'r|s', 's|t'), stringsAsFactors=F)
> transform(df, test=do.call(rbind, strsplit(foo, '|', fixed=TRUE)), stringsAsFactors=F)
  id foo bar test.1 test.2
1  1 a|b p|q      a      b
2  2 b|c r|s      b      c
3  3 c|d s|t      c      d

Multiple columns:

> transform(df, lapply(list(foo,bar),
+ function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar X1 X2 X1.1 X2.1
1  1 a|b p|q  a  b    p    q
2  2 b|c r|s  b  c    r    s
3  3 c|d s|t  c  d    s    t

Better naming of multiple split columns:

> transform(df, lapply({l<-list(foo,bar);names(l)=c('foo','bar');l}, 
+                          function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar foo.1 foo.2 bar.1 bar.2
1  1 a|b p|q     a     b     p     q
2  2 b|c r|s     b     c     r     s
3  3 c|d s|t     c     d     s     t

But as your system grows in size and functionality... i think that returning always a json is not a bad idea at all. Is more a architectural / "big scale design" matter.

You can think about returing always a JSON with two know fields : code and data. Where code is a numeric code specifying the success of the operation to be done and data is any aditional data related with the operation / service requested.

Come on, when we use a backend a service provider, any service can be checked to see if it worked well.

So i stick, to not let spring manage this, exposing hybrid returning operations (Some returns data other nothing...).. instaed make sure that your server expose a more homogeneous interface. Is more simple at the end of the day.

There are at least three ways to disable the use of unobtrusive JavaScript for client-side validation:

1. Add the following to the web.config file:

   <configuration>
     <appSettings>
       <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
     </appSettings>
   </configuration>

2. Set the value of the System.Web.UI.ValidationSettings.UnobtrusiveValidationMode static property to System.Web.UI.UnobtrusiveValidationMode.None
3. Set the value of the System.Web.UI.Page.UnobtrusiveValidationMode instance property to System.Web.UI.UnobtrusiveValidationMode.None

To disable the functionality on a per page basis, I prefer to set the Page.UnobtrusiveValidationMode property using the page directive:

<%@ Page Language="C#" UnobtrusiveValidationMode="None" %>

I would like to add some of my findings:

If you are using GitBash, then make sure the SSH key is stored in ~/.ssh/id_rsa.

By Default GitBash searches for ~/.ssh/id_rsaas default path for SSH key.

Even the file name id_rsa matters. If you save your SSH key in another filename or path, it will throw the Permission Denied(publickey)error.

As per comments, First you need to install an instance of SQL Server if you don't already have one - https://msdn.microsoft.com/en-us/library/ms143219.aspx

Once this is installed you must connect to this instance (server) and then you can create a database here - https://msdn.microsoft.com/en-US/library/ms186312.aspx

Simply pass your word into the following function:

function highlight_words(word) {
    const page = document.body.innerHTML;
    document.body.innerHTML = page.replace(new RegExp(word, "gi"), (match) => `<mark>${match}</mark>`);
}

Usage:

highlight_words("hello")

This will highlight all instances of the word on the page.

The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax

But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.

You would call it like this:

$.ajax({
  url: 'mypage.html',
  success: function(){
    alert('success');
  },
  error: function(){
    alert('failure');
  }
});

I have shown the success and error function taking no arguments, but they can receive arguments.

The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.

The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.

I'm using SourceTree along with TortoiseMerge/Diff, which is very easy and convinient diff/merge tool.

If you'd like to use it as well, then:

1. Get standalone version of TortoiseMerge/Diff (quite old, since it doesn't ship standalone since version 1.6.7 of TortosieSVN, that is since July 2011). Links and details in this answer.

2. Unzip TortoiseIDiff.exe and TortoiseMerge.exe to any folder (c:\Program Files (x86)\Atlassian\SourceTree\extras\ in my case).

3. In SourceTree open Tools > Options > Diff > External Diff / Merge. Select TortoiseMerge in both dropdown lists.

4. Hit OK and point SourceTree to your location of TortoiseIDiff.exe and TortoiseMerge.exe.

After that, you can select Resolve Conflicts > Launch External Merge Tool from context menu on each conflicted file in your local repository. This will open up TortoiseMerge, where you can easily deal with all the conflicts, you have. Once finished, simply close TortoiseMerge (you don't even need to save changes, this will probably be done automatically) and after few seconds SourceTree should handle that gracefully.

The only problem is, that it automatically creates backup copy, even though proper option is unchecked.

site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default.

There are standard locations:

• Unix (pure)¹: prefix/lib/pythonX.Y/site-packages
• Unix (non-pure): exec-prefix/lib/pythonX.Y/site-packages
• Windows: prefix\Lib\site-packages

¹ Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.

site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards.

This is how I fixed this problem:

I had the following:

Controller:

ViewData["DealerTypes"] = Helper.SetSelectedValue(listOfValues, selectedValue) ;

View

<%=Html.DropDownList("DealerTypes", ViewData["DealerTypes"] as SelectList)%>

Changed by the following:

View

<%=Html.DropDownList("DealerTypesDD", ViewData["DealerTypes"] as SelectList)%>

It appears that the DropDown must not have the same name has the ViewData name :S weird but it worked.

Please, take a look at my library: http://sites.google.com/site/easybashgui

It is intended to handle, with the same commands set, indifferently all four big tools "kdialog", "Xdialog", "cdialog" and "zenity", depending if X is running or not, if D.E. is KDE or Gnome or other. There are 15 different functions ( among them there are two called "progress" and "adjust" )...

Bye :-)

I want to share an available option that doesn't seem to be mentioned here yet:

rumpy.random.permutation(x)

Will generate a random permutation of array x. Not exactly what you asked for, but it is a potential solution to similar questions.

why not just check if the value you want to check is equal to itself cast as an integer as shown below?

def isInt(val):
    return val == int(val)

If you want to make interactive console:

#!/usr/bin/env ruby

require "readline"
addends = []
while addend_string = Readline.readline("> ", true)
  addends << addend_string.to_i
  puts "#{addends.join(' + ')} = #{addends.sum}"
end

Usage (assuming you put above snippet into summator file in current directory):

chmod +x summator
./summator
> 1
1 = 1
> 2
1 + 2 = 3

Use Ctrl + D to exit

Jon Skeet has written a library called morelinq which has a DistinctBy() operator. See here for the implementation. Your code would look like

IEnumerable<Note> distinctNotes = Notes.DistinctBy(note => note.Author);

Update: After re-reading your question, Kirk has the correct answer if you're just looking for a distinct set of Authors.

Added sample, several fields in DistinctBy:

res = res.DistinctBy(i => i.Name).DistinctBy(i => i.ProductId).ToList();

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

These extension methods are pretty useful for me when parsing form input before putting into the database

public static int? ToInt(this string input) 
{
    int val;
    if (int.TryParse(input, out val))
        return val;
    return null;
}

public static DateTime? ToDate(this string input)
{
    DateTime val;
    if (DateTime.TryParse(input, out val))
        return val;
    return null;
}

public static decimal? ToDecimal(this string input)
{
    decimal val;
    if (decimal.TryParse(input, out val))
        return val;
    return null;
}

Using fall-through like in your first example is clearly OK, and I would not consider it a real fall-through.

The second example is dangerous and (if not commented extensively) non-obvious. I teach my students not to use such constructs unless they consider it worth the effort to devote a comment block to it, which describes that this is an intentional fall-through, and why this solution is better than the alternatives. This discourages sloppy use, but it still makes it allowed in the cases where it is used to an advantage.

This is more or less equivalent to what we did in space projects when someone wanted to violate the coding standard: they had to apply for dispensation (and I was called on to advise about the ruling).

The short answer: there is no difference.

The long answer: CHARACTER VARYING is the official type name from the ANSI SQL standard, which all compliant databases are required to support. VARCHAR is a shorter alias which all modern databases also support. I prefer VARCHAR because it's shorter and because the longer name feels pedantic. However, postgres tools like pg_dump and \d will output character varying.

This thread is old but was the first one to come up so I thought id share my solution too. Apart from having named routes in your routes.php file. This error can also occur when you have duplicate URLs in your routes file, but with different names, the error can be misleading in this scenario. Example

Route::any('official/form/reject-form', 'FormStatus@rejectForm')->name('reject-form');  


Route::any('official/form/accept-form', 'FormStatus@acceptForm')->name('accept-form');

Changing one of the names solves the problem. Copy pasting and fatigue will get you to this problem :).

You can also use chr(176) to print the degree sign. Here is an example using python 3.6.5 interactive shell:

It seems that GSon don't support JAXB. By using JAXB annotated class to create or process the JSON message, I can share the same class to create the Restful Web Service interface by using spring MVC.

public class aiubMain {
public static void main(String args[]) throws MalformedURLException{
    //home frame = new home();
    java.net.URL imgUrl2 = home.class.getResource("Campus.gif");

Icon icon = new ImageIcon(imgUrl2);
JLabel label = new JLabel(icon);

JFrame f = new JFrame("Animation");
f.getContentPane().add(label);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
}

One possibility is, if you are familiar with PDF format:

1. Create some simply PDF with one page (Page should be contained within one object)
2. Copy object multiply times
3. Add references to the copied objects to the page catalog
4. Fix xref table

You get an valid document of any size, entire file will be processed by a reader.

To convert a data frame column to numeric you just have to do:-

factor to numeric:-

data_frame$column <- as.numeric(as.character(data_frame$column))

function printr($data)
{
   echo "<pre>";
      print_r($data);
   echo "</pre>";
}

And call your function on the page you need, don't forget to include the file where you put your function in for example: functions.php

include('functions.php');

printr($data);

This is possibly an old thread but I was working on datetimes recently and was stuck with similar issue so I ended up creating a utility of mine which looks like this,

This utility would take a string date and would return an optional date object

        func toDate(dateFormat: DateFormatType) -> Date? {
        let formatter = DateFormatter()
        formatter.timeZone = NSTimeZone(name: "UTC") as TimeZone?
        formatter.dateFormat = dateFormat.rawValue
        let temp = formatter.date(from: self)
        return formatter.date(from: self)
        }

the DateFormatType enum looks like this

        enum DateFormatType : String {
        case type1 = "yyyy-MM-dd - HH:mm:ss"
        case type2 = "dd/MM/yyyy"
        case type3 = "yyyy/MM/dd"
    }

One important thing I would like to mention here is the line

formatter.timeZone = NSTimeZone(name: "UTC") as TimeZone?

it's very important that you add this line because without this the DateFormatter would use it's default conversions to convert the date and you might end up seeing different dates if you are working with a remote team and get all sorts of issues with data depending on dates.

Hope this helps

$str = "http://www.vimeo.com/1234567";
$s = explode("/",$str);
print end($s);

I know this doesn't answer your question, but just to help other people. If you are trying to convert "true" or "false" strings to boolean:

Try Boolean.Parse

bool val = Boolean.Parse("true"); ==> true
bool val = Boolean.Parse("True"); ==> true
bool val = Boolean.Parse("TRUE"); ==> true
bool val = Boolean.Parse("False"); ==> false
bool val = Boolean.Parse("1"); ==> Exception!
bool val = Boolean.Parse("diffstring"); ==> Exception!

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

If you are positive that none of the fields to be updated are serialized, the solutions above will work well.

However, if any of the fields that need updating contain serialized data, an SQL Query or a simple search/replace on a dump file, will break serialization (unless the replaced string has exactly the same number of characters as the searched string).

To be sure, a "serialized" field looks like this:

a:1:{s:13:"administrator";b:1;}  

The number of characters in the relevant data is encoded as part of the data.
Serialization is a way to convert "objects" into a format easily stored in a database, or to easily transport object data between different languages.
Here is an explanation of different methods used to serialize object data, and why you might want to do so, and here is a WordPress-centric post: Serialized Data, What Does That Mean And Why is it so Important? in plain language.

It would be amazing if MySQL had some built in tool to handle serialized data automatically, but it does not, and since there are different serialization formats, it would not even make sense for it to do so.

wp-cli
Some of the answers above seemed specific to WordPress databases, which serializes much of its data. WordPress offers a command line tool, wp search-replace, that does handle serialization.
A basic command would be:

    wp search-replace 'an-old-string' 'a-new-string' --dry-run

However, WordPress emphasizes that the guid should never be changed, so it recommends skipping that column.
It also suggests that often times you'll want to skip the wp_users table.
Here's what that would look like:

wp search-replace 'https://old-domain.com' 'https://shiney-new-domain.com' --skip-columns=guid --skip-tables=wp_users --dry-run

Note: I added the --dry-run flag so a copy-paste won't automatically ruin anyone's database. After you're sure the script does what you want, run it again without that flag.

Plugins
If you are using WordPress, there are also many free and commercial plugins available that offer a gui interface to do the same, packaged with many additional features.

Interconnect/it php script
Interconnect/it offers a php script to handle serialized data: Safe Search and Replace tool. It was created for use on WordPress sites, but it looks like it can be used on any database serialized by PHP.
Many companies, including WordPress itself, recommends this tool. Instructions here, about 3/4 down the page.

I simplify the code a little bit.

from scipy.stats import ttest_ind
ttest_ind(*my_data.groupby('Category')['value'].apply(lambda x:list(x)))

#pragma push/pop are often a solution for this kind of problems, but in this case why don't you just remove the unreferenced variable?

try
{
    // ...
}
catch(const your_exception_type &) // type specified but no variable declared
{
    // ...
}

If this isn't made obvious by the the previous answers:

:bd will close the current buffer. If you don't want to grab the buffer list.

For Swift 3, you can use index(where:) and include a closure that does the comparison of an object in the array ($0) with whatever you are looking for.

var array = ["alpha", "beta", "gamma"]
if let index = array.index(where: {$0 == "beta"}) {
  array.remove(at: index)
}

So I can tell there aren't enough opinions or reinvented wheels in this thread, so I decided to spice things up.

Below is a procedure that:

• is focused (only affects) on sequences that are associated with tables
• works for both SERIAL and GENERATED AS IDENTITY columns
• works for good_column_names and "BAD_column_123" names
• automatically assigns the respective sequences' defined start value if the table is empty
• allows for a specific sequences to be affected only (in schema.table.column notation)
• has a preview mode

For Mac via homebrew:

brew tap petere/postgresql,

brew install <formula> (eg: brew install petere/postgresql/postgresql-9.6)

Remove old Postgres:

brew unlink postgresql

brew link -f postgresql-9.6

If any error happen, don't forget to read and follow brew instruction in each step.

you can do like this:

if("merchant_id" in thisSession){ /** will return true if exist */
 console.log('Exist!');
}

or

if(thisSession["merchant_id"]){ /** will return its value if exist */
 console.log('Exist!');
}

You can use this syntax:

#!/bin/bash

echo " Write in your age: "
read age

if [[ "$age" -le 7 || "$age" -ge 65 ]] ; then
    echo " You can walk in for free "
elif [[ "$age" -gt 7 && "$age" -lt 65 ]] ; then
    echo " You have to pay for ticket "
fi

You'll need to keep the current value of the input in state (or pass changes in its value up to a parent via a callback function, or sideways, or <your app's state management solution here> such that it eventually gets passed back into your component as a prop) so you can derive the disabled prop for the button.

Example using state:

<meta charset="UTF-8">_x000D_
<script src="https://fb.me/react-0.13.3.js"></script>_x000D_
<script src="https://fb.me/JSXTransformer-0.13.3.js"></script>_x000D_
<div id="app"></div>_x000D_
<script type="text/jsx;harmony=true">void function() { "use strict";_x000D_
_x000D_
var App = React.createClass({_x000D_
  getInitialState() {_x000D_
    return {email: ''}_x000D_
  },_x000D_
  handleChange(e) {_x000D_
    this.setState({email: e.target.value})_x000D_
  },_x000D_
  render() {_x000D_
    return <div>_x000D_
      <input name="email" value={this.state.email} onChange={this.handleChange}/>_x000D_
      <button type="button" disabled={!this.state.email}>Button</button>_x000D_
    </div>_x000D_
  }_x000D_
})_x000D_
_x000D_
React.render(<App/>, document.getElementById('app'))_x000D_
_x000D_
}()</script>

This is using dataframes from the pandas package. The "index" part can be either a single index, a list of indices, or a list of booleans. This can be read about in the documentation: https://pandas.pydata.org/pandas-docs/stable/indexing.html

So the index part specifies a subset of the rows to pull out, and the (optional) column_name specifies the column you want to work with from that subset of the dataframe. So if you want to update the 'class' column but only in rows where the class is currently set as 'versicolor', you might do something like what you list in the question:

iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'

On Button click event write this:

Uri uri = Uri.parse("http://www.google.com"); // missing 'http://' will cause crashed
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

that open the your URL.

Pass java.text.Collator.getInstance() to Collections.sort method ; it will sort Alphabetically while ignoring case sensitive.

        ArrayList<String> myArray = new ArrayList<String>();
        myArray.add("zzz");
        myArray.add("xxx");
        myArray.add("Aaa");
        myArray.add("bb");
        myArray.add("BB");
        Collections.sort(myArray,Collator.getInstance());

You need to use the CSS white-space attribute.

In particular, white-space: nowrap and white-space: pre are the most commonly used values. The first one seems to be what you 're after.

var data=[];
var $el=$("#my-select");
$el.find('option:selected').each(function(){
    data.push({value:$(this).val(),text:$(this).text()});
});
console.log(data)

*Updated

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

Yep, that would be the enumerate function! Or more to the point, you need to do:

list(enumerate([3,7,19]))

[(0, 3), (1, 7), (2, 19)]

Alternatively you can also accomplish this with getElementsByName

<select id="mySelect" name="val" size="1" >
<option value="A">Apple</option>
<option value="C">Cars</option>
<option value="H">Honda</option>
<option value="F">Fiat</option>
<option value="I">Indigo</option>                    
</select> 

So in matching on the option value of "C" we could remove Cars from the list.

var selectobject = document.getElementsByName('val')[0];
for (var i=0; i<selectobject.length; i++){
if (selectobject.options[i].value == 'C' )
    selectobject.remove(i);
  }

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

As described here input and output extension will detected by ffmpeg so there is no need to worry about the formats, simply run this command:

ffmpeg -i inputFile.ogg outputFile.mp3

see this article!

1. identify UNC par or local drive path by searching index of ":"

2. if its is UNC PATH you cam map UNC path

3. code to execute drive name is mapped drive name < UNC Mapped Drive or Local Drive>.

   using System.IO;
   
   private long GetTotalFreeSpace(string driveName)
   {
   foreach (DriveInfo drive in DriveInfo.GetDrives())
   {
       if (drive.IsReady && drive.Name == driveName)
       {
           return drive.TotalFreeSpace;
       }
   }
   return -1;
   }
   

4. unmap after you requirement done.

In Bootstrap 3, .form-control (the class you give your inputs) has a width of 100%, which allows you to wrap them into col-lg-X divs for arrangement. Example from the docs:

<div class="row">
  <div class="col-lg-2">
    <input type="text" class="form-control" placeholder=".col-lg-2">
  </div>
  <div class="col-lg-3">
    <input type="text" class="form-control" placeholder=".col-lg-3">
  </div>
  <div class="col-lg-4">
    <input type="text" class="form-control" placeholder=".col-lg-4">
  </div>
</div>

See under Column sizing.

It's a bit different than in Bootstrap 2.3.2, but you get used to it quickly.

As far as I know there's no way to do a blanket delete of any cookie set on the domain. You can clear a cookie if you know the name and if the script is on the same domain as the cookie.

You can set the value to empty and the expiration date to somewhere in the past:

var mydate = new Date();
mydate.setTime(mydate.getTime() - 1);
document.cookie = "username=; expires=" + mydate.toGMTString(); 

There's an excellent article here on manipulating cookies using javascript.

you can also add below code in AndroidManifest.xml.

android:icon="@android:color/transparent"

It will work fine.

But I found that this gives a problem as the launcher icon also become transparent.

So I used:

getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));

and it worked fine.

But if you are having more than one activity and want to make the icon on an activity transparent then the previous approach will work.

Try this:

runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1" 

It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.

If you have another variable also referring to the same dictionary, there is a big difference:

>>> d = {"stuff": "things"}
>>> d2 = d
>>> d = {}
>>> d2
{'stuff': 'things'}
>>> d = {"stuff": "things"}
>>> d2 = d
>>> d.clear()
>>> d2
{}

This is because assigning d = {} creates a new, empty dictionary and assigns it to the d variable. This leaves d2 pointing at the old dictionary with items still in it. However, d.clear() clears the same dictionary that d and d2 both point at.

Why not simply return your calculated value and let the caller modify the global variable. It's not a good idea to manipulate a global variable within a function, as below:

Var1 = 1
Var2 = 0

def function(): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1

Var1 = function()

or even make local copies of the global variables and work with them and return the results which the caller can then assign appropriately

def function():
v1, v2 = Var1, Var2
# calculate using the local variables v1 & v2
return v1 - 1

Var1 = function()

function add_more() {

var text_count = document.getElementById('text_count').value;
var div_cmp = document.getElementById('div_cmp');
var values = div_cmp.innnerHTML;
var count = parseInt(text_count);
divContent = '';

for (i = 1; i <= count; i++) {

    var cmp_text = document.getElementById('cmp_name_' + i).value;
    var cmp_textarea = document.getElementById('cmp_remark_' + i).value;
    divContent += '<div id="div_cmp_' + i + '">' +
        '<input type="text" align="top" name="cmp_name[]" id="cmp_name_' + i + '" value="' + cmp_text + '" >' +
        '<textarea rows="1" cols="20" name="cmp_remark[]" id="cmp_remark_' + i + '">' + cmp_textarea + '</textarea>' +
        '</div>';
}

var newCount = count + 1;

if (document.getElementById('div_cmp_' + newCount) == null) {
    var newText = '<div id="div_cmp_' + newCount + '">' +
        '<input type="text" align="top" name="cmp_name[]" id="cmp_name_' + newCount + '" value="" >' +
        '<textarea rows="1" cols="20" name="cmp_remark[]" id="cmp_remark_' + newCount + '"  ></textarea>' +
        '</div>';
    //content = div_cmp.innerHTML;
    div_cmp.innerHTML = divContent + newText;
} else {
    document.getElementById('div_cmp_' + newCount).innerHTML = '<input type="text" align="top" name="cmp_name[]" id="cmp_name_' + newCount + '" value="" >' +
        '<textarea rows="1" cols="20" name="cmp_remark[]" id="cmp_remark_' + newCount + '"  ></textarea>';
}

document.getElementById('text_count').value = newCount;

}

Adding to the answer from Ignacio Vazquez-Abrams. This will allow for the + sign to precede the integer, and it will allow any number of zeros as decimal points. For example, this will allow +45.00000000 to be considered an integer.
However, $1 must be formatted to contain a decimal point. 45 is not considered an integer here, but 45.0 is.

if [[ $1 =~ ^-?[0-9]+.?[0]+$ ]]; then
    echo "yes, this is an integer"
elif [[ $1 =~ ^\+?[0-9]+.?[0]+$ ]]; then
    echo "yes, this is an integer"
else
    echo "no, this is not an integer"
fi

For the special case of existing Windows Forms applications:

There is a way - though I don't know how well it works.
It goes like this:
Take the Windows Forms implementation from Mono.
Port it to .NET Core or NetStandard.

Recompile your Windows Forms applications against the new System.Windows.Forms.
Fix anything that may be broken by .NET Core.
Pray that mono implements the parts you need flawlessly.
(If it doesn't, you can always stop praying, and send the Mono project a pull request with your fix/patch/feature.)

Here's my CoreFX Windows Forms repository:
https://github.com/ststeiger/System.CoreFX.Forms

You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.

It goes by this syntax: ${VARIABLE:-default}.

The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.

If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".

I waited a bit on @QuinnTaylor to update his answer, but since he didn't, here's the answer a bit more clearly and in a way that it will load on XCode7 (and perhaps greater). I used this in a Cocoa application, but it likely will work okay with an iOS application as well. Has no ARC errors.

Paste before any @implementation section in your AppDelegate.m or AppDelegate.mm file.

    void *buffer = malloc(bufferSize);

    size_t numBytesEncrypted = 0;
    CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding,

    free(buffer); //free the buffer;

Paste these two functions in the @implementation class you desire. In my case, I chose @implementation AppDelegate in my AppDelegate.mm or AppDelegate.m file.

- (NSString *) encryptString:(NSString*)plaintext withKey:(NSString*)key {
    NSData *data = [[plaintext dataUsingEncoding:NSUTF8StringEncoding] AES256EncryptWithKey:key];
    return [data base64EncodedStringWithOptions:kNilOptions];
}

- (NSString *) decryptString:(NSString *)ciphertext withKey:(NSString*)key {
    NSData *data = [[NSData alloc] initWithBase64EncodedString:ciphertext options:kNilOptions];
    return [[NSString alloc] initWithData:[data AES256DecryptWithKey:key] encoding:NSUTF8StringEncoding];
}

i think using getRotationv() doesn't help because http://developer.android.com/reference/android/view/Display.html#getRotation%28%29 getRotation() Returns the rotation of the screen from its "natural" orientation.

so unless you know the "natural" orientation, rotation is meaningless.

i found an easier way,

  Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
  Point size = new Point();
  display.getSize(size);
  int width = size.x;
  int height = size.y;
  if(width>height)
    // its landscape

please tell me if there is a problem with this someone?

The --net=host option is used to make the programs inside the Docker container look like they are running on the host itself, from the perspective of the network. It allows the container greater network access than it can normally get.

Normally you have to forward ports from the host machine into a container, but when the containers share the host's network, any network activity happens directly on the host machine - just as it would if the program was running locally on the host instead of inside a container.

While this does mean you no longer have to expose ports and map them to container ports, it means you have to edit your Dockerfiles to adjust the ports each container listens on, to avoid conflicts as you can't have two containers operating on the same host port. However, the real reason for this option is for running apps that need network access that is difficult to forward through to a container at the port level.

For example, if you want to run a DHCP server then you need to be able to listen to broadcast traffic on the network, and extract the MAC address from the packet. This information is lost during the port forwarding process, so the only way to run a DHCP server inside Docker is to run the container as --net=host.

Generally speaking, --net=host is only needed when you are running programs with very specific, unusual network needs.

Lastly, from a security perspective, Docker containers can listen on many ports, even though they only advertise (expose) a single port. Normally this is fine as you only forward the single expected port, however if you use --net=host then you'll get all the container's ports listening on the host, even those that aren't listed in the Dockerfile. This means you will need to check the container closely (especially if it's not yours, e.g. an official one provided by a software project) to make sure you don't inadvertently expose extra services on the machine.

You can tell any click that bubbles all the way up the DOM to hide the dropdown, and any click that makes it to the parent of the dropdown to stop bubbling.

/* Anything that gets to the document
   will hide the dropdown */
$(document).click(function(){
  $("#dropdown").hide();
});

/* Clicks within the dropdown won't make
   it past the dropdown itself */
$("#dropdown").click(function(e){
  e.stopPropagation();
});

Demo: http://jsbin.com/umubad/2/edit

Try this instead:

public class MyTest {
        @Rule
        public TestName testName = new TestName();

        @Rule
        public TestWatcher testWatcher = new TestWatcher() {
            @Override
            protected void starting(final Description description) {
                String methodName = description.getMethodName();
                String className = description.getClassName();
                className = className.substring(className.lastIndexOf('.') + 1);
                System.err.println("Starting JUnit-test: " + className + " " + methodName);
            }
        };

        @Test
        public void testA() {
                assertEquals("testA", testName.getMethodName());
        }

        @Test
        public void testB() {
                assertEquals("testB", testName.getMethodName());
        }
}

The output looks like this:

Starting JUnit-test: MyTest testA
Starting JUnit-test: MyTest testB

NOTE: This DOES NOT work if your test is a subclass of TestCase! The test runs but the @Rule code just never runs.

That is only possible if that site has declared anchors in the page. It is done by giving a tag a name or id attribute, so look for any of those close to where you want to link to.

And then the syntax would be

<a href="page.html#anchor">text</a>

You have to go to Control Panel>Programs>Turn Windows features on or off. Then, check "Telnet Client" and save the changes. You might have to wait about a few minutes before the change could take effect.

With SQL server 2008 and more, using this query:

ALTER TABLE [RecipeInventorys] ALTER COLUMN [RecipeName] varchar(550)

Set environment variables and use headers to receive them:

You can create new environment variables with RewriteRule lines, as mentioned by OP:

RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

But if you can't get a server-side script to work, how can you then read this environment variable? One solution is to set a header:

Header set TEST_FOOBAR "%{REDIRECT_TEST0}e"

The value accepts format specifiers, including the %{NAME}e specifier for environment variables (don't forget the lowercase e). Sometimes, you'll need to add the REDIRECT_ prefix, but I haven't worked out when the prefix gets added and when it doesn't.
