Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

# coding: utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

You could also use the exclude option in tsconfig.json file like so:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "declaration": false,
    "noImplicitAny": false,
    "removeComments": true,
    "noLib": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true
  },
  "exclude": [
    "node_modules"
  ]
}

You can expend the following function in order to pull out more parameters from the DB before the insert:

--
-- insert_employee  (Function) 
--
CREATE OR REPLACE FUNCTION insert_employee(p_emp_id in number, p_emp_name in varchar2, p_emp_address in varchar2, p_emp_state in varchar2, p_emp_position in varchar2, p_emp_manager in varchar2) 
RETURN VARCHAR2 AS

   p_state_id varchar2(30) := '';
 BEGIN    
      select state_id 
      into   p_state_id
      from states where lower(emp_state) = state_name;

      INSERT INTO Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager) VALUES 
                (p_emp_id, p_emp_name, p_emp_address, p_state_id, p_emp_position, p_emp_manager);

    return 'SUCCESS';

 EXCEPTION 
   WHEN others THEN
    RETURN 'FAIL';
 END;
/

you should add style="display:none" in any of <tr> that you want to hide.

PhiLho has mentioned AutoRuns in passing, but I think it deserves elaboration.

It doesn't scan the whole registry, just the parts containing references to things which get loaded automatically (EXEs, DLLs, drivers etc.) which is probably what you are interested in. It doesn't track changes but can export to a text file, so you can run it before and after installation and do a diff.

It's important to add that the main difference of running mvn with -U and without -U is that -U will override your local SNAPSHOT jars with remote SNAPSHOT jars.

Local SNAPSHOT jars created from local mvn install in cases where you have other modules of your proj that generate jars.

There are a lot of sources for selenium - here is good one for simple use Selenium, and here is a example snippet too Selenium Examples

You can find a lot of good sources to use selenium, it's not too hard to get it set up and start using it.

Consider the situation where you have more than one constructor. Will the initialization be different for the different constructors? If they will be the same, then why repeat for each constructor? This is in line with kokos statement, but may not be related to parameters. Let's say, for example, you want to keep a flag which shows how the object was created. Then that flag would be initialized differently for different constructors regardless of the constructor parameters. On the other hand, if you repeat the same initialization for each constructor you leave the possibility that you (unintentionally) change the initialization parameter in some of the constructors but not in others. So, the basic concept here is that common code should have a common location and not be potentially repeated in different locations. So I would say always put it in the declaration until you have a specific situation where that no longer works for you.

The default height is 44.0f for a tableview cell I believe. You must be having your datasource in hand in a Array? Then just check if [array count]*44.0f goes beyond the frame bounds and if so set tableview.scrollEnabled = NO, else set it to YES. Do it where you figure the datasource out for that particular tableview.

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>

tl;dr

…parsed … from a String … time zone is not specified … I want to set a specific time zone

LocalDateTime.parse( "2018-01-23T01:23:45.123456789" )  // Parse string, lacking an offset-from-UTC and lacking a time zone, as a `LocalDateTime`.
    .atZone( ZoneId.of( "Africa/Tunis" ) )              // Assign the time zone for which you are certain this date-time was intended. Instantiates a `ZonedDateTime` object.

No Time Zone in j.u.Date

As the other correct answers stated, a java.util.Date has no time zone^†. It represents UTC/GMT (no time zone offset). Very confusing because its toString method applies the JVM's default time zone when generating a String representation.

Avoid j.u.Date

For this and many other reasons, you should avoid using the built-in java.util.Date & .Calendar & java.text.SimpleDateFormat. They are notoriously troublesome.

Instead use the java.time package bundled with Java 8.

java.time

The java.time classes can represent a moment on the timeline in three ways:

• UTC (Instant)
• With an offset (OffsetDateTime with ZoneOffset)
• With a time zone (ZonedDateTime with ZoneId)

Instant

In java.time, the basic building block is Instant, a moment on the time line in UTC. Use Instant objects for much of your business logic.

Instant instant = Instant.now();

OffsetDateTime

Apply an offset-from-UTC to adjust into some locality’s wall-clock time.

Apply a ZoneOffset to get an OffsetDateTime.

ZoneOffset zoneOffset = ZoneOffset.of( "-04:00" );
OffsetDateTime odt = OffsetDateTime.ofInstant( instant , zoneOffset );

ZonedDateTime

Better is to apply a time zone, an offset plus the rules for handling anomalies such as Daylight Saving Time (DST).

Apply a ZoneId to an Instant to get a ZonedDateTime. Always specify a proper time zone name. Never use 3-4 abbreviations such as EST or IST that are neither unique nor standardized.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

LocalDateTime

If the input string lacked any indicator of offset or zone, parse as a LocalDateTime.

If you are certain of the intended time zone, assign a ZoneId to produce a ZonedDateTime. See code example above in tl;dr section at top.

Formatted Strings

Call the toString method on any of these three classes to generate a String representing the date-time value in standard ISO 8601 format. The ZonedDateTime class extends standard format by appending the name of the time zone in brackets.

String outputInstant = instant.toString(); // Ex: 2011-12-03T10:15:30Z
String outputOdt = odt.toString(); // Ex: 2007-12-03T10:15:30+01:00
String outputZdt = zdt.toString(); // Ex: 2007-12-03T10:15:30+01:00[Europe/Paris]

For other formats use the DateTimeFormatter class. Generally best to let that class generate localized formats using the user’s expected human language and cultural norms. Or you can specify a particular format.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Joda-Time

While Joda-Time is still actively maintained, its makers have told us to migrate to java.time as soon as is convenient. I leave this section intact as a reference, but I suggest using the java.time section above instead.

In Joda-Time, a date-time object (DateTime) truly does know its assigned time zone. That means an offset from UTC and the rules and history of that time zone’s Daylight Saving Time (DST) and other such anomalies.

String input = "2014-01-02T03:04:05";
DateTimeZone timeZone = DateTimeZone.forID( "Asia/Kolkata" );
DateTime dateTimeIndia = new DateTime( input, timeZone );
DateTime dateTimeUtcGmt = dateTimeIndia.withZone( DateTimeZone.UTC );

Call the toString method to generate a String in ISO 8601 format.

String output = dateTimeIndia.toString();

Joda-Time also offers rich capabilities for generating all kinds of other String formats.

If required, you can convert from Joda-Time DateTime to a java.util.Date.

Java.util.Date date = dateTimeIndia.toDate();

Search StackOverflow for "joda date" to find many more examples, some quite detailed.

^†Actually there is a time zone embedded in a java.util.Date, used for some internal functions (see comments on this Answer). But this internal time zone is not exposed as a property, and cannot be set. This internal time zone is not the one used by the toString method in generating a string representation of the date-time value; instead the JVM’s current default time zone is applied on-the-fly. So, as shorthand, we often say “j.u.Date has no time zone”. Confusing? Yes. Yet another reason to avoid these tired old classes.

Having just messed around with this, it's useful to kjnow that the e.X / e.Y points are relative to the control, so if (as I was) you are adding a context menu to a listview or something similar, you will want to adjust it with the form's origin. In the example below I've added 20 to the x/y so that the menu appears slightly to the right and under the cursor.

cmDelete.Show(this, new Point(e.X + ((Control)sender).Left+20, e.Y + ((Control)sender).Top+20));

An Android Context is an Interface (in the general sense, not in the Java sense; in Java, Context is actually an abstract class!) that allows access to application specific resources and class and information about application environment.

If your android app was a web app, your context would be something similar to ServletContext (I am not making an exact comparison here).

Your activities and services also extend Context, so they inherit all those methods to access the environment information in which the app is running.

1. Pass By Value / Call By Value

   void printvalue(int x) 
   {
       x = x + 1 ;
       cout << x ;  // 6
   }

   int x = 5;
   printvalue(x);
   cout << x;    // 5

In call by value, when you pass a value to printvalue(x) i.e. the argument which is 5, it is copied to void printvalue(int x). Now, we have two different values 5 and the copied value 5 and these two values are stored in different memory locations. So if you make any change inside void printvalue(int x) it won't reflect back to the argument.

2. Pass By Reference/ Call By Reference

   void printvalue(int &x) 
   {
      x = x + 1 ;
      cout << x ; // 6
   }

   int x = 5;
   printvalue(x);
   cout << x;   // 6

In call by reference, there's only one difference. We use & i.e. the address operator. By doing
void printvalue(int &x) we are referring to the address of x which tells us that it both refers to the same location. Hence, any changes made inside the function will reflect outside.

Now that you're here, you should also know about ...

3. Pass By Pointer/ Call By Address

   void printvalue(int* x) 
   {
      *x = *x + 1 ;
      cout << *x ; // 6
   }

   int x = 5;
   printvalue(&x);
   cout << x;   // 6

In pass by address, the pointer int* x holds the address passed to it printvalue(&x). Hence, any changes done inside the function will reflect outside.

In my case, I had to add using System.Data.Entity;

The max length of a varchar is

65535

divided by the max byte length of a character in the character set the column is set to (e.g. utf8=3 bytes, ucs2=2, latin1=1).

minus 2 bytes to store the length

minus the length of all the other columns

minus 1 byte for every 8 columns that are nullable. If your column is null/not null this gets stored as one bit in a byte/bytes called the null mask, 1 bit per column that is nullable.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

Just do it like this

NSString * strCheck = @"A\nB";

strCheck = [strCheck stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];  //This is to prevent for fetching string from plist or data structure

label.numberOfLines = 0;

label.lineBreakMode = NSLineBreakByWordWrapping;

label.text = strCheck;

Yes, there are a few of them.

You can also use for 1080 hd values:

240p: &vq=small , 360p: &vq=medium , 480p: &vq=large , 720p: &vq=hd720 , &vq=hd1080

Use a raw string:

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'

Note that although it looks wrong, it's actually right. There is only one backslash in the string foo.

This happens because when you just type foo at the prompt, python displays the result of __repr__() on the string. This leads to the following (notice only one backslash and no quotes around the printed string):

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'
>>> print(foo)
baz "\"

And let's keep going because there's more backslash tricks. If you want to have a backslash at the end of the string and use the method above you'll come across a problem:

>>> foo = r'baz \'
  File "<stdin>", line 1
    foo = r'baz \'
                 ^  
SyntaxError: EOL while scanning single-quoted string

Raw strings don't work properly when you do that. You have to use a regular string and escape your backslashes:

>>> foo = 'baz \\'
>>> print(foo)
baz \

However, if you're working with Windows file names, you're in for some pain. What you want to do is use forward slashes and the os.path.normpath() function:

myfile = os.path.normpath('c:/folder/subfolder/file.txt')
open(myfile)

This will save a lot of escaping and hair-tearing. This page was handy when going through this a while ago.

I think you have to go for

$arrayname[indexname] = $value;

1.get all tables and views from information_schema.tables, include those of information_schema and pg_catalog.

select * from information_schema.tables

2.get tables and views belong certain schema

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog')

3.get tables only(almost \dt)

select * from information_schema.tables
    where table_schema not in ('information_schema', 'pg_catalog') and
    table_type = 'BASE TABLE'

Everything in a Java program not explicitly set to something by the programmer, is initialized to a zero value.

• For references (anything that holds an object) that is null.
• For int/short/byte/long that is a 0.
• For float/double that is a 0.0
• For booleans that is a false.
• For char that is the null character '\u0000' (whose decimal equivalent is 0).

When you create an array of something, all entries are also zeroed. So your array contains five zeros right after it is created by new.

Note (based on comments): The Java Virtual Machine is not required to zero out the underlying memory when allocating local variables (this allows efficient stack operations if needed) so to avoid random values the Java Language Specification requires local variables to be initialized.

# ignore these
*
# except foo
!foo

For me, the issue resolved when I updated the Gradle build version. Don't know why?

You must check the certificate hash code.

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain,
    errors) =>
        {
            var hashString = certificate.GetCertHashString();
            if (hashString != null)
            {
                var certHashString = hashString.ToLower();
                return certHashString == "dec2b525ddeemma8ccfaa8df174455d6e38248c5";
            }
            return false;
        };

You should not try to do this directly. Design your tasks to work with a CancellationToken, and cancel them this way.

In addition, I would recommend changing your main thread to function via a CancellationToken as well. Calling Thread.Abort() is a bad idea - it can lead to various problems that are very difficult to diagnose. Instead, that thread can use the same Cancellation that your tasks use - and the same CancellationTokenSource can be used to trigger the cancellation of all of your tasks and your main thread.

This will lead to a far simpler, and safer, design.

I was facing the same issue and then I closed and reopened cmd.exe to get mvn -vto propagate to my command prompt.

If cmd was open when you set the variables they will not be available in that session.

I had the same problem when running: dotnet ef migrations add InitialCreate so what I did is tried to build the project using: dotnet build command.

It throws an error : Startup.cs(20,27): error CS0103: bla bla for example. which you can trace to find the error in your code.

Then i refactored the code and ran: dotnet build again to check any errors until there is no errors and build is succeded. Then ran: dotnet ef migrations add InitialCreate then the build succeded.

Use os.path.abspath():

os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))

sys.argv[0] in your case is just a script name, no directory, so os.path.dirname() returns an empty string.

os.path.abspath() turns that into a proper absolute path with directory name.

My case? I had startup file, but it is excluded in the project. I just included it and the error left.

I'm using Ookii dialogs for a while and it work nice for WPF.

Here's the direct page:

I fixed this problem with sql command line:

connect system/<password>
alter system set processes=300 scope=spfile;
alter system set sessions=300 scope=spfile;

Restart database.

package com.infy.test;

import java.util.Scanner ;
import java.lang.String ;

public class Test1 {


    public static void main (String[]args)
    {

        String a  =null;


        Scanner scan = new Scanner(System.in);
        System.out.println("*********White Space Remover Program************\n");
        System.out.println("Enter your string\n");
    a = scan.nextLine();
        System.out.println("Input String is  :\n"+a);


        String b= a.replaceAll("\\s+","");

        System.out.println("\nOutput String is  :\n"+b);


    }
}

Easy as pie! :P

#include <iostream>

static int current = 1;

struct print
{
    print() { std::cout << current++ << std::endl; }
};

int main()
{
    print numbers [1000];
}

A good example would be a cache.

For recently accessed objects, you want to keep them in memory, so you hold a strong pointer to them. Periodically, you scan the cache and decide which objects have not been accessed recently. You don't need to keep those in memory, so you get rid of the strong pointer.

But what if that object is in use and some other code holds a strong pointer to it? If the cache gets rid of its only pointer to the object, it can never find it again. So the cache keeps a weak pointer to objects that it needs to find if they happen to stay in memory.

This is exactly what a weak pointer does -- it allows you to locate an object if it's still around, but doesn't keep it around if nothing else needs it.

There is a static method on the Thread Class that will return the number of active threads controlled by the JVM:

Thread.activeCount()

Returns the number of active threads in the current thread's thread group.

Additionally, external debuggers should list all active threads (and allow you to suspend any number of them) if you wish to monitor them in real-time.

If you want to center the content horizontally and vertically, but don't know in prior how high your page will be, you have to you use JavaScript.

HTML:

<body>
    <div id="content">...</div>
</body>

CSS:

#content {
    max-width: 1000px;
    margin: auto;
    left: 1%;
    right: 1%;
    position: absolute;
}

JavaScript (using jQuery):

$(function() {
    $(window).on('resize', function resize()  {
        $(window).off('resize', resize);
        setTimeout(function () {
            var content = $('#content');
            var top = (window.innerHeight - content.height()) / 2;
            content.css('top', Math.max(0, top) + 'px');
            $(window).on('resize', resize);
        }, 50);
    }).resize();
});

Good News

As of today 11th April 2020, this is easily possible with backdrop-filter CSS property which is now a stable feature in Chrome, Safari & Edge.

I wanted this in our Hybrid mobile app so also available in Android/Chrome Webview & Safari WebView.

1. https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter
2. https://caniuse.com/#search=backdrop-filter

Code Example:

Simply add the CSS property:

.my-class {
    backdrop-filter: blur(30px);
    background: transparent;     // Make sure there is not backgorund
}

UI Example 1

See it working in this pen or try the demo:

#main-wrapper {_x000D_
  width: 300px;_x000D_
  height: 300px;_x000D_
  background: url("https://i.picsum.photos/id/1001/500/500.jpg") no-repeat center;_x000D_
  background-size: cover;_x000D_
  position: relative;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
.my-effect {_x000D_
  position: absolute;_x000D_
  top: 300px;_x000D_
  left: 0;_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  font-size: 22px;_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  color: black;_x000D_
  -webkit-backdrop-filter: blur(15px);_x000D_
  backdrop-filter: blur(15px);_x000D_
  transition: top 700ms;_x000D_
}_x000D_
_x000D_
#main-wrapper:hover .my-effect {_x000D_
  top: 0;_x000D_
}

<h4>Hover over the image to see the effect</h4>_x000D_
_x000D_
<div id="main-wrapper">_x000D_
  <div class="my-effect">_x000D_
    Glossy effect worked!_x000D_
  </div>_x000D_
</div>

UI Example 2

Let's take an example of McDonald's app because it's quite colourful. I took its screenshot and added as the background in the body of my app.

I wanted to show a text on top of it with the glossy effect. Using backdrop-filter: blur(20px); on the overlay above it, I was able to see this:

There is actually a nice Gem called local_time by basecamp to do all of that on client side only, I believe:

Any easy way to cover ALL file inputs is to just style your input[type=button] and drop this in globally to turn file inputs into buttons:

$(document).ready(function() {
    $("input[type=file]").each(function () {
        var thisInput$ = $(this);
        var newElement = $("<input type='button' value='Choose File' />");
        newElement.click(function() {
            thisInput$.click();
        });
        thisInput$.after(newElement);
        thisInput$.hide();
    });
});

Here's some sample button CSS that I got from http://cssdeck.com/labs/beautiful-flat-buttons:

input[type=button] {
  position: relative;
  vertical-align: top;
  width: 100%;
  height: 60px;
  padding: 0;
  font-size: 22px;
  color:white;
  text-align: center;
  text-shadow: 0 1px 2px rgba(0, 0, 0, 0.25);
  background: #454545;
  border: 0;
  border-bottom: 2px solid #2f2e2e;
  cursor: pointer;
  -webkit-box-shadow: inset 0 -2px #2f2e2e;
  box-shadow: inset 0 -2px #2f2e2e;
}
input[type=button]:active {
  top: 1px;
  outline: none;
  -webkit-box-shadow: none;
  box-shadow: none;
}

When using Monkey Script I noticed that DispatchPress(KEYCODE_BACK) is doing nothing which really suck. In many cases this is due to the fact that the Activity doesn't consume the Key event. The solution to this problem is to use a mix of monkey script and adb shell input command in a sequence.

1 Using monkey script gave some great timing control. Wait a certain amount of second for the activity and is a blocking adb call.
2 Finally sending adb shell input keyevent 4 will end the running APK.

EG

adb shell monkey -p com.my.application -v -v -v -f /sdcard/monkey_script.txt 1
adb shell input keyevent 4

If you are using Windows, you should set the same environment variables, but Windows style:

set http_proxy=<your_http_proxy:proxy_port>
set https_proxy=<your_https_proxy:proxy_port>

That will work for your current cmd.exe. If you want to do this more permanent, y suggest you to use environment variables on your system.

Actually, yagmail took a bit different approach.

It will by default send HTML, with automatic fallback for incapable email-readers. It is not the 17th century anymore.

Of course, it can be overridden, but here goes:

import yagmail
yag = yagmail.SMTP("[email protected]", "mypassword")

html_msg = """<p>Hi!<br>
              How are you?<br>
              Here is the <a href="http://www.python.org">link</a> you wanted.</p>"""

yag.send("[email protected]", "the subject", html_msg)

For installation instructions and many more great features, have a look at the github.

Open a new Search pane in Developer Tools by:

• pressing Ctrl+Shift+F (Cmd+Option+I on mac)
• clicking the overflow menu (?) in DevTools,
• clicking the overflow menu in the Console (?) and choosing the Search option

You can search across all your scripts with support for regular expressions and case sensitivity.

Click any match to load that file/section in the scripts panel.

Make sure 'Search in anonymous and content scripts' is checked in the DevTools Preferences (F1). This will return results from within iframes and HTML inline scripts:

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

As of mid-2015, I believe this is the best solution:

<input type="number" pattern="[0-9]*" inputmode="numeric">

This will give you the numeric keypad on both Android and iOS:

It also gives you the expected desktop behavior with the up/down arrow buttons and keyboard friendly up/down arrow key incrementing:

Try it in this code snippet:

<form>_x000D_
  <input type="number" pattern="[0-9]*" inputmode="numeric">_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

By combining both type="number" and pattern="[0-9]*, we get a solution that works everywhere. And, its forward compatible with the future HTML 5.1 proposed inputmode attribute.

Note: Using a pattern will trigger the browser's native form validation. You can disable this using the novalidate attribute, or you can customize the error message for a failed validation using the title attribute.

If you need to be able to enter leading zeros, commas, or letters - for example, international postal codes - check out this slight variant.

I have looked at all the responses and tested them all. I pretty much compiled them all into one as a 'Safety closure'. This in c#

NOTE you can change the param from IModule app to that of the actual driver.

 public class WebDriverCleaner
{

    public static void CloseWebDriver(IModule app)
    {
        try
        {
            if (app?.GetDriver() != null)
            {
                app.GetDriver().Close();
                Thread.Sleep(3000); // Gives time for everything to close before quiting
                app.GetDriver().Quit();
                app.GetDriver().Dispose();
                KillProcessAndChildren("chromedriver.exe"); // One more to make sure we get rid of them chromedrivers.
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }
    }

    public static void KillProcessAndChildren(string p_name)
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher
            ("Select * From Win32_Process Where Name = '" + p_name + "'");

        ManagementObjectCollection moc = searcher.Get();
        foreach (ManagementObject mo in moc)
        {
            try
            {
                KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
            }
            catch (ArgumentException)
            {
                break;
            }
        }

    }


    public static void KillProcessAndChildren(int pid)
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Process Where ParentProcessID=" + pid);
        ManagementObjectCollection moc = searcher.Get();

        foreach (ManagementObject mo in moc)
        {
            try
            {
                KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
            }
            catch
            {
                break;
            }
        }

        try
        {
            Process proc = Process.GetProcessById(pid);
            proc.Kill();
        }
        catch (ArgumentException)
        {
            // Process already exited.
        }
    }

}

Here's a way to get dimensions of a png file without needing a third-party module. From http://coreygoldberg.blogspot.com/2013/01/python-verify-png-file-and-get-image.html

import struct

def get_image_info(data):
    if is_png(data):
        w, h = struct.unpack('>LL', data[16:24])
        width = int(w)
        height = int(h)
    else:
        raise Exception('not a png image')
    return width, height

def is_png(data):
    return (data[:8] == '\211PNG\r\n\032\n'and (data[12:16] == 'IHDR'))

if __name__ == '__main__':
    with open('foo.png', 'rb') as f:
        data = f.read()

    print is_png(data)
    print get_image_info(data)

When you run this, it will return:

True
(x, y)

And another example that includes handling of JPEGs as well: http://markasread.net/post/17551554979/get-image-size-info-using-pure-python-code

Add two bindings to your website, one for local access and another for LAN access like so:

Open IIS and select your local website (that you want to access from your local network) from the left panel:

Connections > server (user-pc) > sites > local site

Open Bindings on the right panel under Actions tab add these bindings:

1. Local:

   Type: http
   Ip Address: All Unassigned
   Port: 80
   Host name: samplesite.local
   

2. LAN:

   Type: http
   Ip Address: <Network address of the hosting machine ex. 192.168.0.10>
   Port: 80
   Host name: <Leave it blank>
   

Voila, you should be able to access the website from any machine on your local network by using the host's LAN IP address (192.168.0.10 in the above example) as the site url.

NOTE:

if you want to access the website from LAN using a host name (like samplesite.local) instead of an ip address, add the host name to the hosts file on the local network machine (The hosts file can be found in "C:\Windows\System32\drivers\etc\hosts" in windows, or "/etc/hosts" in ubuntu):

192.168.0.10 samplesite.local

Just used the Nathan's solution and it works fine. I needed to convert ISO-8859-1 to Unicode:

string isocontent = Encoding.GetEncoding("ISO-8859-1").GetString(fileContent, 0, fileContent.Length);
byte[] isobytes = Encoding.GetEncoding("ISO-8859-1").GetBytes(isocontent);
byte[] ubytes = Encoding.Convert(Encoding.GetEncoding("ISO-8859-1"), Encoding.Unicode, isobytes);
return Encoding.Unicode.GetString(ubytes, 0, ubytes.Length);

There are a number of ways that you could do this, but the fastest might be to use IndexOf to find the index position of the letter you want to replace and then substring out the text before and after what you want to replace.

I got

No 'Access-Control-Allow-Origin' header is present

and the problem was with the URL I was providing. I was providing the URL without a route, e.g., https://misty-valley-1234.herokuapp.com/.

When I added a path it worked, e.g., https://misty-valley-1234.herokuapp.com/messages. With GET requests it worked either way but with POST responses it only worked with the added path.

tv.setText( a1 + " ");

This will resolve your problem.

Why dont you just add a new Partial View with i's own specific controller passing the required model to the partial view and finally Render the mentioned partial view on your Layout.cshtml using RenderPartial or RenderAction ?

I use this method for showing the logged in user's info like name , profile picture and etc.

You can change set orientation of linearlayout programmatically by:

LinearLayout linearLayout =new linearLayout(this);//just to give the clarity
linearLayout.setOrientation(LinearLayout.VERTICAL);

I will soon released a new version of my app to support to galaxy ace.

You can download here: https://play.google.com/store/apps/details?id=droid.pr.coolflashlightfree

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

Add following dll files to bin folder:

DotNetOpenAuth.AspNet.dll
DotNetOpenAuth.Core.dll
DotNetOpenAuth.OAuth.Consumer.dll
DotNetOpenAuth.OAuth.dll
DotNetOpenAuth.OpenId.dll
DotNetOpenAuth.OpenId.RelyingParty.dll

If you will not need them, delete dependentAssemblies from config named 'DotNetOpenAuth.Core' etc..

Inline SVG coming from 3rd party sources (like Google charts) may not contain XML namespace attribute (xmlns="http://www.w3.org/2000/svg") in SVG element (or maybe it's removed once SVG is rendered - neither browser inspector nor jQuery commands from browser console show the namespace in SVG element).

When you need to re-purpose these svg snippets for your other needs (background-image in CSS or img element in HTML) watch out for the missing namespace. Without the namespace browsers may refuse to display SVG (regardless of the encoding utf8 or base64).

You can use the below code for creating a TextBox as read-only.

Method 1

 @Html.TextBoxFor(model => model.Fields[i].TheField, new { @readonly = true })

Method 2

@Html.TextBoxFor(model => model.Fields[i].TheField, new { htmlAttributes = new {disabled = "disabled"}})

If you want to use enhanced loop, you can convert the string to charArray

for (char ch : exampleString.toCharArray()) {
  System.out.println(ch);
}

If you give find an absolute path to start with, it will print absolute paths. For instance, to find all .htaccess files in the current directory:

find "$(pwd)" -name .htaccess

or if your shell expands $PWD to the current directory:

find "$PWD" -name .htaccess

find simply prepends the path it was given to a relative path to the file from that path.

Greg Hewgill also suggested using pwd -P if you want to resolve symlinks in your current directory.

Use COPY command like this:

COPY foo.txt /data/foo.txt
# where foo.txt is the relative path on host
# and /data/foo.txt is the absolute path in the image

read more details for COPY in the official documentation

An alternative would be to use ADD but this is not the best practise if you dont want to use some advanced features of ADD like decompression of tar.gz files.If you still want to use ADD command, do it like this:

ADD abc.txt /data/abc.txt
# where abc.txt is the relative path on host
# and /data/abc.txt is the absolute path in the image

read more details for ADD in the official documentation

You have created a table with ID as PRIMARY KEY, which satisfies UNIQUE and NOT NULL constraints, so you can't make the ID as NULL by inserting name field, so ID should also be inserted.

The error message indicates this.

It's compiled to bytecode which can be used much, much, much faster.

The reason some files aren't compiled is that the main script, which you invoke with python main.py is recompiled every time you run the script. All imported scripts will be compiled and stored on the disk.

Important addition by Ben Blank:

It's worth noting that while running a compiled script has a faster startup time (as it doesn't need to be compiled), it doesn't run any faster.

export default is used to export a single class, function or primitive from a script file.

The export can also be written as

export default function SafeString(string) {
  this.string = string;
}

SafeString.prototype.toString = function() {
  return "" + this.string;
};

This is used to import this function in another script file

Say in app.js, you can

import SafeString from './handlebars/safe-string';

A little about export

As the name says, it's used to export functions, objects, classes or expressions from script files or modules

Utiliites.js

export function cube(x) {
  return x * x * x;
}
export const foo = Math.PI + Math.SQRT2;

This can be imported and used as

App.js

import { cube, foo } from 'Utilities';
console.log(cube(3)); // 27
console.log(foo);    // 4.555806215962888

Or

import * as utilities from 'Utilities';
console.log(utilities.cube(3)); // 27
console.log(utilities.foo);    // 4.555806215962888

When export default is used, this is much simpler. Script files just exports one thing. cube.js

export default function cube(x) {
  return x * x * x;
};

and used as App.js

import Cube from 'cube';
console.log(Cube(3)); // 27

The number in parentheses in a type declaration is display width, which is unrelated to the range of values that can be stored in a data type. Just because you can declare Int(20) does not mean you can store values up to 10^20 in it:

[...] This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces. ...

The display width does not constrain the range of values that can be stored in the column, nor the number of digits that are displayed for values having a width exceeding that specified for the column. For example, a column specified as SMALLINT(3) has the usual SMALLINT range of -32768 to 32767, and values outside the range allowed by three characters are displayed using more than three characters.

For a list of the maximum and minimum values that can be stored in each MySQL datatype, see here.

Poor man's profiling, no extensions required. Supports nested profiles and percent of total:

function p_open($flag) {
    global $p_times;
    if (null === $p_times)
        $p_times = [];
    if (! array_key_exists($flag, $p_times))
        $p_times[$flag] = [ 'total' => 0, 'open' => 0 ];
    $p_times[$flag]['open'] = microtime(true);
}

function p_close($flag)
{
    global $p_times;
    if (isset($p_times[$flag]['open'])) {
        $p_times[$flag]['total'] += (microtime(true) - $p_times[$flag]['open']);
        unset($p_times[$flag]['open']);
    }
}

function p_dump()
{
    global $p_times;
    $dump = [];
    $sum  = 0;
    foreach ($p_times as $flag => $info) {
        $dump[$flag]['elapsed'] = $info['total'];
        $sum += $info['total'];
    }
    foreach ($dump as $flag => $info) {
        $dump[$flag]['percent'] = $dump[$flag]['elapsed']/$sum;
    }
    return $dump;
}

Example:

<?php

p_open('foo');
sleep(1);
p_open('bar');
sleep(2);
p_open('baz');
sleep(3);
p_close('baz');
sleep(2);
p_close('bar');
sleep(1);
p_close('foo');

var_dump(p_dump());

Yields:

array:3 [
  "foo" => array:2 [
    "elapsed" => 9.000766992569
    "percent" => 0.4736904954747
  ]
  "bar" => array:2 [
    "elapsed" => 7.0004580020905
    "percent" => 0.36841864946596
  ]
  "baz" => array:2 [
    "elapsed" => 3.0001420974731
    "percent" => 0.15789085505934
  ]
]

Change 'middle' to 'center'. Like so:

<img align="center" ....>

gcloud config set project my-project

You may also set the environment variable $CLOUDSDK_CORE_PROJECT.

There are multiple solution exist but none of them perfect. let's go one by one.

1. Unique Telephony Number (IMEI, MEID, ESN, IMSI)

• This solution needs to request for android.permission.READ_PHONE_STATE to your user which can be hard to justify following the type of application you have made.

• Furthermore, this solution is limited to smartphones because tablets don’t have telephony services. One advantage is that the value survives to factory resets on devices.

2. MAC Address

• You can also try to get a MAC Address from a device having a Wi-Fi or Bluetooth hardware. But, this solution is not recommended because not all of the device have Wi-Fi connection. Even if the user have a Wi-Fi connection, it must be turned on to retrieve the data. Otherwise, the call doesn’t report the MAC Address.

3. Serial Number

• Devices without telephony services like tablets must report a unique device ID that is available via android.os.Build.SERIAL since Android 2.3 Gingerbread. Some phones having telephony services can also define a serial number. Like not all Android devices have a Serial Number, this solution is not reliable.

4. Secure Android ID

• On a device first boot, a randomly value is generated and stored. This value is available via Settings.Secure.ANDROID_ID . It’s a 64-bit number that should remain constant for the lifetime of a device. ANDROID_ID seems a good choice for a unique device identifier because it’s available for smartphones and tablets.

  String androidId = Settings.Secure.getString(getContentResolver(),Settings.Secure.ANDROID_ID);
  

• However, the value may change if a factory reset is performed on the device. There is also a known bug with a popular handset from a manufacturer where every instance have the same ANDROID_ID. Clearly, the solution is not 100% reliable.

5. Use UUID

• As the requirement for most of applications is to identify a particular installation and not a physical device, a good solution to get unique id for an user if to use UUID class. The following solution has been presented by Reto Meier from Google in a Google I/O presentation :

  private static String uniqueID = null;
  private static final String PREF_UNIQUE_ID = "PREF_UNIQUE_ID";
  public synchronized static String id(Context context) {
     if (uniqueID == null) {
         SharedPreferences sharedPrefs = context.getSharedPreferences(
                 PREF_UNIQUE_ID, Context.MODE_PRIVATE);
         uniqueID = sharedPrefs.getString(PREF_UNIQUE_ID, null);
         if (uniqueID == null) {
             uniqueID = UUID.randomUUID().toString();
             Editor editor = sharedPrefs.edit();
             editor.putString(PREF_UNIQUE_ID, uniqueID);
             editor.commit();
         }
     }    return uniqueID;
  }
  

Identify a particular device on Android is not an easy thing. There are many good reasons to avoid that. Best solution is probably to identify a particular installation by using UUID solution. credit : blog

This questions seems a little bit outdated but here is my solution.

I assume that you have already downloaded GlassFish on your hard drive and unzipped the files on a directory.

A - Eclipse MarketPlace / Installing GlassFish Tools

The first thing as it is said on previous answers, you have to downloaded GlassFish Tools from eclipse marketplace;

Help -> EclipseMarket Place

And install GlassFish on the screen below;

B - Adding GlassFish Server

Open Server View, if it is not visible on the bottom of the eclipse, then;

Window -> Show View -> Servers

As the server view is visible, simply click "No servers are available. Click this link to create a new server..." as shown below;

C - Adding GlassFish Server

On the New Server window, select GlassFish as shown below. On my experience, there is only one GlassFish option that I can select, instead of several GlassFish options with versions as you can see down below;

D - Configuring GlassFish & Java Locations

Enter the exact GlassFish location and also Java location as you can see below;

E - Last Step

On the last step of this configuration, just leave everything as it is. For simplicity, I don't define an admin password;

Now everything is all set, hope that this helps!

Just to help out anyone that is having the same issue but specifically using Zsh shell with iTerm 2. It turns out that Zsh doesn't read /etc/inputrc properly, and so fails to understand any key bindings you set up through the preferences!

To fix this, you need to add some key bindings to your .zshrc file, such as:

# key bindings
bindkey "\e[1~" beginning-of-line
bindkey "\e[4~" end-of-line

Note the backslashes in the example above before the "e", the linked article does not show them, so add them into your .zshrc file when adding bindings.

Just to add on to the topic of for in/for/$.each, I added a jsperf test case for using $.each vs for in: http://jsperf.com/each-vs-for-in/2

Different browsers/versions handle it differently, but it seems $.each and straight out for in are the cheapest options performance-wise.

If you're using for in to iterate through an associative array/object, knowing what you're after and ignoring everything else, use $.each if you use jQuery, or just for in (and then a break; once you've reached what you know should be the last element)

If you're iterating through an array to perform something with each key pair in it, should use the hasOwnProperty method if you DON'T use jQuery, and use $.each if you DO use jQuery.

Always use for(i=0;i<o.length;i++) if you don't need an associative array though... lol chrome performed that 97% faster than a for in or $.each

 function resize() {
        var map_obj = document.getElementById("map_canvas");

      /*  map_obj.style.width = "500px";
        map_obj.style.height = "225px";*/
        if (map) {
            map.checkResize();
            map.panTo(new GLatLng(lat,lon));
        }
    }

<body onload="initialize()" onunload="GUnload()" onresize="resize()">
<div id="map_canvas" style="width: 100%; height: 100%">
</div>

For MySQL or PostgreSQL 9.3+, a better way is to use the LEAST and GREATEST functions.

SELECT GREATEST(A.date0, B.date0) AS date0, 
       LEAST(A.date1, B.date1, B.date2) AS date1
FROM A, B
WHERE B.x = A.x

With:

• GREATEST(value [, ...]) : Returns the largest (maximum-valued) argument from values provided
• LEAST(value [, ...]) Returns the smallest (minimum-valued) argument from values provided

Documentation links :

• MySQL http://dev.mysql.com/doc/refman/5.0/en/comparison-operators.html
• Postgres https://www.postgresql.org/docs/current/functions-conditional.html

The following is my solution. Test it if it works for you:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>

            </configuration>
        </execution>
    </executions>
</plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <!-- <classpathPrefix>lib</classpathPrefix> -->
                <!-- <mainClass>test.org.Cliente</mainClass> -->
            </manifest>
            <manifestEntries>
                <Class-Path>lib/</Class-Path>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>

The first plugin puts all dependencies in the target/classes/lib folder, and the second one includes the library folder in the final JAR file, and configures the Manifest.mf file.

But then you will need to add custom classloading code to load the JAR files.

Or, to avoid custom classloading, you can use "${project.build.directory}/lib, but in this case, you don't have dependencies inside the final JAR file, which defeats the purpose.

It's been two years since the question was asked. The problem of nested JAR files persists nevertheless. I hope it helps somebody.

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

I wrote an extension that takes into account all possible cases:

• If access is allowed, then the code onAccessHasBeenGranted will be run.
• If access is not determined, then requestAuthorization(_:) will be called.
• If the user has denied your app photo library access, then the user will be shown a window offering to go to settings and allow access. In this window, the "Cancel" and "Settings" buttons will be available to him. When he presses the "settings" button, your application settings will open.

Usage example:

PHPhotoLibrary.execute(controller: self, onAccessHasBeenGranted: {
    // access granted... 
})

Extension code:

import Photos
import UIKit

public extension PHPhotoLibrary {

   static func execute(controller: UIViewController,
                       onAccessHasBeenGranted: @escaping () -> Void,
                       onAccessHasBeenDenied: (() -> Void)? = nil) {

      let onDeniedOrRestricted = onAccessHasBeenDenied ?? {
         let alert = UIAlertController(
            title: "We were unable to load your album groups. Sorry!",
            message: "You can enable access in Privacy Settings",
            preferredStyle: .alert)
         alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
         alert.addAction(UIAlertAction(title: "Settings", style: .default, handler: { _ in
            if let settingsURL = URL(string: UIApplication.openSettingsURLString) {
               UIApplication.shared.open(settingsURL)
            }
         }))
         controller.present(alert, animated: true)
      }

      let status = PHPhotoLibrary.authorizationStatus()
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAccessHasBeenGranted)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAccessHasBeenGranted()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   }

}

private func onNotDetermined(_ onDeniedOrRestricted: @escaping (()->Void), _ onAuthorized: @escaping (()->Void)) {
   PHPhotoLibrary.requestAuthorization({ status in
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAuthorized)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAuthorized()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   })
}

Something like this should work

CSS:

input {
    float: left;
    clear: left;
    width: 50px;
    line-height: 20px;
}

label {
    float: left;
    vertical-align: middle;
}

I know that this is an old question, but Google threw me here and I think I found a simpler answer.

In Railscasts #179, Ryan Bates used the Ruby standard class OpenURI to do much of what was asked like this:

(Warning: untested code. You might need to change/tweak it.)

require 'open-uri'

File.open("/my/local/path/sample.flv", "wb") do |saved_file|
  # the following "open" is provided by open-uri
  open("http://somedomain.net/flv/sample/sample.flv", "rb") do |read_file|
    saved_file.write(read_file.read)
  end
end

I had this issue until I removed the project in question from the server's deployments (in JBoss Dev Studio, right-click the server and "Remove" the project in the Servers view), then did the following:

1. Restarted the JBoss EAP 6.1 server without any projects deployed.
2. Once the server had started, I then added the project in question to the server.

After this, just restart the server (in debug or run mode) by selecting the server, NOT the project itself.

This seemed to flush any previous settings/states/memory/whatever that was causing the issue, and I no longer got the error.

If you can use an array, do use an array, the length and order of an array are half its worth.

function reducer(obj, fun, temp){
    if(typeof fun=== 'function'){
        if(temp== undefined) temp= '';
        for(var p in obj){
            if(obj.hasOwnProperty(p)){
                temp= fun(obj[p], temp, p, obj);
            }
        }
    }
    return temp;
}
var O={a:{value:1},b:{value:2},c:{value:3}}

reducer(O, function(a, b){return a.value+b;},0);

/* returned value: (Number) 6 */

def norm(vector):
    return sqrt(sum(x * x for x in vector))    

def cosine_similarity(vec_a, vec_b):
        norm_a = norm(vec_a)
        norm_b = norm(vec_b)
        dot = sum(a * b for a, b in zip(vec_a, vec_b))
        return dot / (norm_a * norm_b)

This method seems to be somewhat faster than using sklearn's implementation if you pass in one pair of vectors at a time.

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

For background, see the Understanding ASP.NET dynamic compilation article on MSDN.

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

In order to avoid any dependency you can use java.util.Calendar as follow:

    Calendar now = Calendar.getInstance();
    now.add(Calendar.MINUTE, 10);
    Date teenMinutesFromNow = now.getTime();

In Java 8 we have new API:

    LocalDateTime dateTime = LocalDateTime.now().plus(Duration.of(10, ChronoUnit.MINUTES));
    Date tmfn = Date.from(dateTime.atZone(ZoneId.systemDefault()).toInstant());

#include <iostream>
using namespace std;

template <typename charT>
struct ichar {
    operator charT() const { return toupper(x); }
    charT x;
};
template <typename charT>
static basic_string<ichar<charT> > *istring(basic_string<charT> &s) { return (basic_string<ichar<charT> > *)&s; }
template <typename charT>
static ichar<charT> *istring(const charT *s) { return (ichar<charT> *)s; }

int main()
{
    string s = "The STRING";
    wstring ws = L"The WSTRING";
    cout << istring(s)->find(istring("str")) << " " << istring(ws)->find(istring(L"wstr"))  << endl;
}

A little bit dirty, but short & fast.

With quotes around the date:

mysql> CALL insertEvent('2012.01.01 12:12:12');

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

Best practice is to use an interface to specify the contract and an abstract class as just one implementation thereof. That abstract class can fill in a lot of the boilerplate so you can create an implementation by just overriding what you need to or want to without forcing you to use a particular implementation.

Prior to PHP 5.2.0 and above you should use filter_input() which is especially created for that to get a specific external user inputs such as get, post or cookie variables by name and optionally filters it to avoid any XSS/Injection attacks on your site. For example:

$user = filter_input(INPUT_POST, 'username');

You may use one of INPUT_GET, INPUT_POST, INPUT_COOKIE, INPUT_SERVER, or INPUT_ENV.

By using optional 3rd argument, you can extend it by variety of filters (for validating, sanitizing, filtering or other), e.g. FILTER_SANITIZE_SPECIAL_CHARS, FILTER_SANITIZE_ENCODED, etc.

For example:

<?php
$search_html = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_SPECIAL_CHARS);
$search_url = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_ENCODED);
echo "You have searched for $search_html.\n";
echo "<a href='?search=$search_url'>Search again.</a>";
?>

The syntax is:

mixed filter_input ( int $type , string $variable_name [, int $filter = FILTER_DEFAULT [, mixed $options ]] )

(PHP 5 >= 5.2.0, PHP 7)

See also: Why is better to use filter_input()?

What about invoke-item script.bat.

This works for all cases.

function resizeImg(imgId) {
    var img = document.getElementById(imgId);
    var $img = $(img);
    var maxWidth = 110;
    var maxHeight = 100;
    var width = img.width;
    var height = img.height;
    var aspectW = width / maxWidth;
    var aspectH = height / maxHeight;

    if (aspectW > 1 || aspectH > 1) {
        if (aspectW > aspectH) {
            $img.width(maxWidth);
            $img.height(height / aspectW);
        }
        else {
            $img.height(maxHeight);
            $img.width(width / aspectH);
        }
    }
}

Hold down Ctrl+Shift+P (or cmd on Mac), select "Change Language Mode" and there it is.

But I still can't find a way to make VS Code recognized files with specific extension as some certain language.

To execute your program from the command line, you have to call the python interpreter, like this :

C:\Python27>python hello.py 1 1

If you code resides in another directory, you will have to set the python binary path in your PATH environment variable, to be able to run it, too. You can find detailed instructions here.

It needs to be a jQuery element to use .addClass(), so it needs to be wrapped in $() like this:

function addClassByClick(button){
  $(button).addClass("active")
}

A better overall solution would be unobtrusive script, for example:

<asp:Button ID="Button" runat="server" class="clickable"/>

Then in jquery:

$(function() {                       //run when the DOM is ready
  $(".clickable").click(function() {  //use a class, since your ID gets mangled
    $(this).addClass("active");      //add the class to the clicked element
  });
});

This could have been achieved through a simple one line valueof() sort function. Run code snippet below to see demo.

var homes = [_x000D_
    {_x000D_
        "h_id": "3",_x000D_

console.log(homes);

If you are using GitHub Desktop, then just do the following steps:

1. Close GitHub Desktop and all other applications with open files to your current directory path.
2. Move the whole directory as mentioned above to the new directory location.
3. Open GitHub Desktop and click on the blue (!) "repository not found" icon. Then a dialog will open and you will see a "Locate..." button which will open a popup allowing you to direct its path to a new location.

Very easy no need create class extends LocationListener 1- Variable

            LocationManager.GPS_PROVIDER, 500, 10, mLocationListener);
}

4- onDestroy()

@Override
public void onDestroy() {
    super.onDestroy();
    mLocationManager.removeUpdates(mLocationListener);
}

Pattern p = Pattern.compile("-?\\d+");
Matcher m = p.matcher("There are more than -2 and less than 12 numbers here");
while (m.find()) {
  System.out.println(m.group());
}

... prints -2 and 12.

-? matches a leading negative sign -- optionally. \d matches a digit, and we need to write \ as \\ in a Java String though. So, \d+ matches 1 or more digits.

This is how you do a distinct count query. Note that you have to filter out the nulls.

var useranswercount = (from a in tpoll_answer
where user_nbr != null && answer_nbr != null
select user_nbr).Distinct().Count();

If you combine this with into your current grouping code, I think you'll have your solution.

public long fillDataTempo(String table){
    String[] table = new String[1];
    tabela[0] = table; 
    ContentValues args = new ContentValues();
    args.put(DBOpenHelper.DATA_HORA, new Date().toString());
    args.put(DBOpenHelper.NOME_TABELA, nome_tabela);
    return db.update(DATABASE_TABLE, args, STRING + " LIKE ?" ,tabela);
}

Just you need to use 

//for bold
android:textStyle="bold"

//for italic
android:textStyle="italic"

//for normal
android:textStyle="normal"

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textStyle="bold"
    android:text="@string/userName"
    android:layout_gravity="left"
    android:textSize="16sp"
/>

Before mounting external storage BOOT_COMPLETE is sent execute.if your app is installed to external storage it won't receive BOOT_COMPLETE broadcast message. To prevent this you can install your application in internal storage. you can do this just adding this line in menifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="internalOnly"
... >

Some HTC devices can enable a "fast boot" feature that is more like a deep hibernation and not a real reboot and therefore should not give the BOOT_COMPLETE intent. To recover this you can add this intent filter inside your receiver:

            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
                <action android:name="android.intent.action.QUICKBOOT_POWERON" />
            </intent-filter>

There's a lot of confusion on this topic. Let me see if I can clarify it (Python 3.7):

1. glob.glob('*.txt') :matches all files ending in '.txt' in current directory
2. glob.glob('*/*.txt') :same as 1
3. glob.glob('**/*.txt') :matches all files ending in '.txt' in the immediate subdirectories only, but not in the current directory
4. glob.glob('*.txt',recursive=True) :same as 1
5. glob.glob('*/*.txt',recursive=True) :same as 3
6. glob.glob('**/*.txt',recursive=True):matches all files ending in '.txt' in the current directory and in all subdirectories

So it's best to always specify recursive=True.

Another quick way to do this without a regexp is to replace the characters first, as below:

>>> 'a;bcd,ef g'.replace(';',' ').replace(',',' ').split()
['a', 'bcd', 'ef', 'g']

The cleanest way is use a function of janitor package that is built for exactly this purpose.

janitor::row_to_names(DF,1)

If you want to use any other row than the first one, pass it in the second parameter.

This provides you the code example on sorting map. Basically this is what they provide:

var keys []int
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark1-8      2863149           374 ns/op         152 B/op          5 allocs/op

and this is what I would suggest using instead:

keys := make([]int, 0, len(myMap))
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark2-8      5320446           230 ns/op          80 B/op          2 allocs/op

Full code can be found in this Go Playground.

Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.

function foo() {
    var myajax = $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        async: false, //add this
    });
    return myajax.responseText;
}

You can do this also:

$.ajax({
    type: "POST",
    url: "CHService.asmx/SavePurpose",
    dataType: "text",
    data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
    contentType: "application/json; charset=utf-8",
    async: false, //add this
}).done(function ( data ) {
        Success = true;
}).fail(function ( data ) {
       Success = false;
});

I use forms designed only with Twitter Bootstrap 3. I set defaults functions for validor and run only validate method with rules. I use Icons from FontAweSome, but you can use Glyphicons as in doc example.

jQuery.validator.setDefaults({
    highlight: function (element, errorClass, validClass) {
        if (element.type === "radio") {
            this.findByName(element.name).addClass(errorClass).removeClass(validClass);
        } else {
            $(element).closest('.form-group').removeClass('has-success has-feedback').addClass('has-error has-feedback');
            $(element).closest('.form-group').find('i.fa').remove();
            $(element).closest('.form-group').append('<i class="fa fa-exclamation fa-lg form-control-feedback"></i>');
        }
    },
    unhighlight: function (element, errorClass, validClass) {
        if (element.type === "radio") {
            this.findByName(element.name).removeClass(errorClass).addClass(validClass);
        } else {
            $(element).closest('.form-group').removeClass('has-error has-feedback').addClass('has-success has-feedback');
            $(element).closest('.form-group').find('i.fa').remove();
            $(element).closest('.form-group').append('<i class="fa fa-check fa-lg form-control-feedback"></i>');
        }
    }
});

Done. After run validate function:

$("#default-register-user").validate({
    rules: {
        'login': {
            required: true,
            minlength: 5,
            maxlength: 20
        },
        'email': {
            required: true,
            email: true,
            minlength: 5,
            maxlength: 100
        },
        'password': {
            required: true,
            minlength: 6,
            maxlength: 25
        },
        'confirmpassword': {
            required: true,
            minlength: 5,
            maxlength: 25,
            equalTo: "#password"
        }
    }
});

JSFiddle example

Based on neuront's response I created a simple JQuery method that gets the form data in key-value pairs but it works for multi-selects and for array inputs with name='example[]'.

This is how it is used:

var form_data = $("#form").getFormObject();

You can find an example below of its definition and how it works.

            if ( !Array.isArray(obj[name]) ) {_x000D_
                obj[name] = [ obj[name], item.value ];_x000D_
            } else {_x000D_
               obj[name].push(item.value);_x000D_

The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.

import numpy as np

names  = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 ,  0.5678 ,  0.9123 ])

ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats

np.savetxt('test.txt', ab, fmt="%10s %10.3f")

Update: This example also works properly in Python 3 by using the 'U6' Unicode string dtype, when creating the ab structured array, instead of the 'S6' byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1' in Python 3.

Can you provide your layout xml? Doing so would allow people to recreate the issue with minimal effort.

You might have to set

android:layout_weight="1"

for the item that you want expanded

From the Skullbox article:

TCP (Transmission Control Protocol) is the most commonly used protocol on the Internet. The reason for this is because TCP offers error correction. When the TCP protocol is used there is a "guaranteed delivery." This is due largely in part to a method called "flow control." Flow control determines when data needs to be re-sent, and stops the flow of data until previous packets are successfully transferred. This works because if a packet of data is sent, a collision may occur. When this happens, the client re-requests the packet from the server until the whole packet is complete and is identical to its original.

UDP (User Datagram Protocol) is anther commonly used protocol on the Internet. However, UDP is never used to send important data such as webpages, database information, etc; UDP is commonly used for streaming audio and video. Streaming media such as Windows Media audio files (.WMA) , Real Player (.RM), and others use UDP because it offers speed! The reason UDP is faster than TCP is because there is no form of flow control or error correction. The data sent over the Internet is affected by collisions, and errors will be present. Remember that UDP is only concerned with speed. This is the main reason why streaming media is not high quality.

2) TCP needs more processing at network interface level where as in UDP it’s not.

3) TCP uses, 3 way handshake, congestion control, flow control and other mechanism to make sure the reliable transmission.

4) UDP is mostly used in cases where the packet delay is more serious than packet loss.

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

You can use QuickConverter.

With QuickConverter you can write the converter logic inline with your BindingExpression

Here is an inverted BooleanToVisibility converter:

Visibility="{qc:Binding '!$P ? Visibility.Visible : Visibility.Collapsed', P={Binding Example}}"

You can add QuickConverter via NuGet. Have a look at the documentation for setup. Link: https://quickconverter.codeplex.com/

Try this. Create a shortcut in startup folder and iuput

PowerShell "&.'PathToFile\script.ps1'"

This is the easiest way.

Memcached client library was just recently released as stable. It is being used by digg ( was developed for digg by Andrei Zmievski, now no longer with digg) and implements much more of the memcached protocol than the older memcache client. The most important features that memcached has are:

1. Cas tokens. This made my life much easier and is an easy preventive system for stale data. Whenever you pull something from the cache, you can receive with it a cas token (a double number). You can than use that token to save your updated object. If no one else updated the value while your thread was running, the swap will succeed. Otherwise a newer cas token was created and you are forced to reload the data and save it again with the new token.
2. Read through callbacks are the best thing since sliced bread. It has simplified much of my code.
3. getDelayed() is a nice feature that can reduce the time your script has to wait for the results to come back from the server.
4. While the memcached server is supposed to be very stable, it is not the fastest. You can use binary protocol instead of ASCII with the newer client.
5. Whenever you save complex data into memcached the client used to always do serialization of the value (which is slow), but now with memcached client you have the option of using igbinary. So far I haven't had the chance to test how much of a performance gain this can be.

All of this points were enough for me to switch to the newest client, and can tell you that it works like a charm. There is that external dependency on the libmemcached library, but have managed to install it nonetheless on Ubuntu and Mac OSX, so no problems there so far.

If you decide to update to the newer library, I suggest you update to the latest server version as well as it has some nice features as well. You will need to install libevent for it to compile, but on Ubuntu it wasn't much trouble.

I haven't seen any frameworks pick up the new memcached client thus far (although I don't keep track of them), but I presume Zend will get on board shortly.

UPDATE

Zend Framework 2 has an adapter for Memcached which can be found here

I had exactly the same issue and it was not cross domain but the same domain. I just added this line to the php file which was handling the ajax request.

<?php header('Access-Control-Allow-Origin: *'); ?>

It worked like a charm. Thanks to the poster

I think this is what you are looking for -

select Address1+Address2 as CompleteAddress from YourTable
where Address1+Address2 like '%YourSearchString%'

To prevent a compound word being created when we append address1 with address2, you can use this -

select Address1 + ' ' + Address2 as CompleteAddress from YourTable 
where Address1 + ' ' + Address2 like '%YourSearchString%'

So, '123 Center St' and 'Apt 3B' will not be '123 Center StApt 3B' but will be '123 Center St Apt 3B'.

As Django documentation says:

prefetch_related()

Returns a QuerySet that will automatically retrieve, in a single batch, related objects for each of the specified lookups.

This has a similar purpose to select_related, in that both are designed to stop the deluge of database queries that is caused by accessing related objects, but the strategy is quite different.

select_related works by creating an SQL join and including the fields of the related object in the SELECT statement. For this reason, select_related gets the related objects in the same database query. However, to avoid the much larger result set that would result from joining across a ‘many’ relationship, select_related is limited to single-valued relationships - foreign key and one-to-one.

prefetch_related, on the other hand, does a separate lookup for each relationship, and does the ‘joining’ in Python. This allows it to prefetch many-to-many and many-to-one objects, which cannot be done using select_related, in addition to the foreign key and one-to-one relationships that are supported by select_related. It also supports prefetching of GenericRelation and GenericForeignKey, however, it must be restricted to a homogeneous set of results. For example, prefetching objects referenced by a GenericForeignKey is only supported if the query is restricted to one ContentType.

More information about this: https://docs.djangoproject.com/en/2.2/ref/models/querysets/#prefetch-related

If you reconfigure IIS7 to use your new location, then there's no problem. Just test that the new location is working, before deleting the old location.

Change IIS7 Inetpub path

• Open %windir%\system32\inetsrv\config\applicationhost.config and search for

%SystemDrive%\inetpub\wwwroot

• Change the path.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

Pesonally tested on 10g ;-)

From http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

SwiftJSONParse: Parse JSON like a badass

Dead-simple and easy to read!

Example: get the value "mrap" from nicknames as a String from this JSON response

{
    "other": {
        "nicknames": ["mrap", "Mikee"]
}

It takes your json data NSData as it is, no need to preprocess.

let parser = JSONParser(jsonData)

if let handle = parser.getString("other.nicknames[0]") {
    // that's it!
}

Disclaimer: I made this and I hope it helps everyone. Feel free to improve on it!

Generally

static: no need to create object we can directly call using

ClassName.methodname()

Non Static: we need to create a object like

ClassName obj=new ClassName()
obj.methodname();

If I understood what you want:

dictionary.Add("key", new List<string>()); 

later...

dictionary["key"].Add("string to your list");

Some sites that document and explain this and other bit twiddling hacks are:

  (http://graphics.stanford.edu/~seander/bithacks.html#DetermineIfPowerOf2)
• http://bits.stephan-brumme.com/

And the grandaddy of them, the book "Hacker's Delight" by Henry Warren, Jr.:

• http://www.hackersdelight.org/

As Sean Anderson's page explains, the expression ((x & (x - 1)) == 0) incorrectly indicates that 0 is a power of 2. He suggests to use:

(!(x & (x - 1)) && x)

to correct that problem.

What you also can do, if it's something you installed on your system, is to add the directory that contains the shared libraries to your /etc/ld.so.conf file, or make a new file in /etc/ld.so.conf.d/

(I've both checked RHEL5 and Ubuntu distribution so I think it's generic for linux)

The ldconfig program will make sure they are system-wide included.

See the following link for more information: www.dwheeler.com/secure-programs/Secure-Programs-HOWTO/dlls.html

You can convert an int to an unsigned int. The conversion is valid and well-defined.

Since the value is negative, UINT_MAX + 1 is added to it so that the value is a valid unsigned quantity. (Technically, 2^N is added to it, where N is the number of bits used to represent the unsigned type.)

In this case, since int on your platform has a width of 32 bits, 62 is subtracted from 2³², yielding 4,294,967,234.

For Windows 8 64 bit with a Nexus 10 device, this worked for me:

Use this if you also want to consider non-javascript users:

echo ("<SCRIPT LANGUAGE='JavaScript'>
           window.alert('Succesfully Updated')
           window.location.href='http://someplace.com';
       </SCRIPT>
       <NOSCRIPT>
           <a href='http://someplace.com'>Successfully Updated. Click here if you are not redirected.</a>
       </NOSCRIPT>");

I feel like properties are about letting you get the overhead of writing getters and setters only when you actually need them.

Java Programming culture strongly advise to never give access to properties, and instead, go through getters and setters, and only those which are actually needed. It's a bit verbose to always write these obvious pieces of code, and notice that 70% of the time they are never replaced by some non-trivial logic.

In Python, people actually care for that kind of overhead, so that you can embrace the following practice :

• Do not use getters and setters at first, when if they not needed
• Use @property to implement them without changing the syntax of the rest of your code.

We need to put some kind of control that can wrap text like textblock/textbox

 <Label Width="120" Height="100" >
        <TextBlock TextWrapping="Wrap">
            this is a very long text inside a textblock and this needs to be on multiline.
        </TextBlock>
    </Label>

You need to write your file to the request stream:

using (var reqStream = req.GetRequestStream()) 
{    
    reqStream.Write( ... ) // write the bytes of the file
}

String arr= "[1,2]";
List<Integer> arrList= JSON.parseArray(arr,Integer.class).stream().collect(Collectors.toList());
Integer[] intArr = ArrayUtils.toObject(arrList.stream().mapToInt(Integer::intValue).toArray());

Take a look at the @Deprecated annotation.

expanding on @leaf 's answer, here's one that can take multiple characters:

var trim = function (s, t) {
  var tr, sr
  tr = t.split('').map(e => `\\\\${e}`).join('')
  sr = s.replace(new RegExp(`^[${tr}]+|[${tr}]+$`, 'g'), '')
  return sr
}

The error message clearly says that the default constructor has been deleted implicitly. It even says why: the class contains a non-static, const variable, which would not be initialized by the default ctor.

class X {
    const int x;
};

Since X::x is const, it must be initialized -- but a default ctor wouldn't normally initialize it (because it's a POD type). Therefore, to get a default ctor, you need to define one yourself (and it must initialize x). You can get the same kind of situation with a member that's a reference:

class X { 
    whatever &x;
};

It's probably worth noting that both of these will also disable implicit creation of an assignment operator as well, for essentially the same reason. The implicit assignment operator normally does members-wise assignment, but with a const member or reference member, it can't do that because the member can't be assigned. To make assignment work, you need to write your own assignment operator.

This is why a const member should typically be static -- when you do an assignment, you can't assign the const member anyway. In a typical case all your instances are going to have the same value so they might as well share access to a single variable instead of having lots of copies of a variable that will all have the same value.

It is possible, of course, to create instances with different values though -- you (for example) pass a value when you create the object, so two different objects can have two different values. If, however, you try to do something like swapping them, the const member will retain its original value instead of being swapped.

You are missing the event parameter on your function.

$(document).on("click",".appDetails", function (event) {
    alert(event.target.id);
});

First, the problem of the missing prefix.

If you consume something in your layout file that comes from a third party, you may need to consume its prefix as well, something like "droidfu:" which occurs in several places in the XML construct below:

<com.github.droidfu.widgets.WebImageView android:id="@+id/webimage"
          android:layout_width="75dip"
          android:layout_height="75dip"
          android:background="#CCC"
          droidfu:autoLoad="true"
          droidfu:imageUrl="http://www.android.com/images/opensourceprojec.gif"
          droidfu:progressDrawable="..."
          />

This comes out of the JAR, but you'll also need to add the new "xmlns:droidfu"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:droidfu="http://github.com/droidfu/schema"
      ...>

or you get the unbound prefix error. For me, this was a failure to copy and paste all of the supplied example from the third-party library's pages.

req.query will return a JS object after the query string is parsed.

/user?name=tom&age=55 - req.query would yield {name:"tom", age: "55"}

req.params will return parameters in the matched route. If your route is /user/:id and you make a request to /user/5 - req.params would yield {id: "5"}

req.param is a function that peels parameters out of the request. All of this can be found here.

UPDATE

If the verb is a POST and you are using bodyParser, then you should be able to get the form body in you function with req.body. That will be the parsed JS version of the POSTed form.

The setw manipulator function will be of help here.

It's an old question, but here are some comments...

1. In SQL, the DELETE command accepts a parameter "CASCADE", which allows you to specify that dependent objects should also be deleted. This is an example of a DELETE parameter that makes sense, but 'man rm' could provide others. How would these cases possibly be implemented in REST/HTTP without a parameter?
2. @Jan, it seems to be a well-established convention that the path part of the URL identifies a resource, whereas the querystring does not (at least not necessarily). Examples abound: getting the same resource but in a different format, getting specific fields of a resource, etc. If we consider the querystring as part of the resource identifier, it is impossible to have a concept of "different views of the same resource" without turning to non-RESTful mechanisms such as HTTP content negotiation (which can be undesirable for many reasons).

Try the common syntax instead:

if (strlen($message)<140) {
    echo "less than 140";
}
else
    if (strlen($message)>140) {
        echo "more than 140";
    }
    else {
        echo "exactly 140";
    }

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.

In contrast, JSTL works entirely with scoped attributes, either at page, request or session scope. You need to rework your scriptlet to fish test out as an attribute:

<c:set var="test" value="test1"/>
<%
  String resp = "abc";
  String test = pageContext.getAttribute("test");
  resp = resp + test;
  pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>

If you look at the docs for <c:set>, you'll see you can specify scope as page, request or session, and it defaults to page.

Better yet, don't use scriptlets at all: they make the baby jesus cry.

Alternative

If your console is not empty, right click on the Console area > Preferences... > change the value for the Console buffer size (characters) (recommended) or uncheck the Limit console output (not recommended):

You can pass any data you want through the button object itself (by accessing CALayers keyValue dict).

Set your target like this (with the ":")

[myButton addTarget:self action:@selector(buttonTap:) forControlEvents:UIControlEventTouchUpInside];

Add your data(s) to the button itself (well the .layer of the button that is) like this:

NSString *dataIWantToPass = @"this is my data";//can be anything, doesn't have to be NSString
[myButton.layer setValue:dataIWantToPass forKey:@"anyKey"];//you can set as many of these as you'd like too!

Then when the button is tapped you can check it like this:

-(void)buttonTap:(UIButton*)sender{

    NSString *dataThatWasPassed = (NSString *)[sender.layer valueForKey:@"anyKey"];
    NSLog(@"My passed-thru data was: %@", dataThatWasPassed);

}

Here is a function that works with jQuery (for height only, not width):

function setHeight(jq_in){
    jq_in.each(function(index, elem){
        // This line will work with pure Javascript (taken from NicB's answer):
        elem.style.height = elem.scrollHeight+'px'; 
    });
}
setHeight($('<put selector here>'));

Note: The op asked for a solution that does not use Javascript, however this should be helpful to many people who come across this question.

I think much has already been said, about RSS vs VSZ. From an administrator/programmer/user perspective, when I design/code applications I am more concerned about the RSZ, (Resident memory), as and when you keep pulling more and more variables (heaped) you will see this value shooting up. Try a simple program to build malloc based space allocation in loop, and make sure you fill data in that malloc'd space. RSS keeps moving up. As far as VSZ is concerned, it's more of virtual memory mapping that linux does, and one of its core features derived out of conventional operating system concepts. The VSZ management is done by Virtual memory management of the kernel, for more info on VSZ, see Robert Love's description on mm_struct and vm_struct, which are part of basic task_struct data structure in kernel.

The simplest way is using Ergo as your reverse proxy: https://github.com/cristianoliveira/ergo

You set your services and its IP:PORT and ergo routes it for you :).

You can achieve the same using nginx or apache but you will need to configure them.

For Float

var decimal=  /^[-+]?[0-9]+\.[0-9]+$/; 

if (!price.match(decimal)) {
      alert('Please enter valid float');
      return false;
    }

For integer

var number = /^\d+$/; 

if (!price.match(number)) {
      alert('Please enter valid integer');
      return false;
    }

I spent over 3 hours to find out solution. Actually port 80 was being used by "system" service so I tried to change port from 80 to 8080 in "httpd" file but same problem raised "port 80 is used by system". It had driven me mad for 3 hours as every thing was changed like port , localhost server etc pointing to 8080.

At last I found mistake that was server root. Basically "Server Root" in "httpd" should be pointing to apache foler of xampp. In my case that's was

ServerRoot "xampp/apache"

I just changed it as follows:

ServerRoot "C:/xampp/apache" 

It has worked successfully and now everything is running with OK status.

Maybe you need "sys." before:

select * from sys.registry$history;

UPDATE: for your updated question

variable.match(/\[[0-9]+\]/);

Try this:

variable.match(/[0-9]+/);    // for unsigned integers
variable.match(/[-0-9]+/);   // for signed integers
variable.match(/[-.0-9]+/);  // for signed float numbers

Hope this helps!

Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.

here "n" could be the number of temp variables present

rm(list = c(paste("temp",c(1:n),sep="")))

The quickest (and most flexible) way is to use np.where, which chooses between two arrays according to a mask(array of true and false values):

import numpy as np
a = np.random.randint(0, 5, size=(5, 4))
b = np.where(a<3,0,1)
print('a:',a)
print()
print('b:',b)

which will produce:

a: [[1 4 0 1]
 [1 3 2 4]
 [1 0 2 1]
 [3 1 0 0]
 [1 4 0 1]]

b: [[0 1 0 0]
 [0 1 0 1]
 [0 0 0 0]
 [1 0 0 0]
 [0 1 0 0]]

On windows 10 i highly recommend to install Linux Bash Shell.

Here is a nice guide to set it up: https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

just follow the steps, choose your linux distribution and avoid as much possible to work with node on cmd since obvious instability.

Take in consideration Microsoft strongly warns against adding or modifying Linux files with Windows software, as described here: howtogeek.com/261383/how-to-access-your-ubuntu-bash-files-in-windows-and-your-windows-system-drive-in-bash/

Hope it helps!

This works perfectly for adding rows and controls in a TableLayoutPanel.

Define a blank Tablelayoutpanel with 3 columns in the design page

    Dim TableLayoutPanel3 As New TableLayoutPanel()

    TableLayoutPanel3.Name = "TableLayoutPanel3"

    TableLayoutPanel3.Location = New System.Drawing.Point(32, 287)

    TableLayoutPanel3.AutoSize = True

    TableLayoutPanel3.Size = New System.Drawing.Size(620, 20)

    TableLayoutPanel3.ColumnCount = 3

    TableLayoutPanel3.CellBorderStyle = TableLayoutPanelCellBorderStyle.Single

    TableLayoutPanel3.BackColor = System.Drawing.Color.Transparent

    TableLayoutPanel3.ColumnStyles.Add(New ColumnStyle(SizeType.Percent, 26.34146!))

    TableLayoutPanel3.ColumnStyles.Add(New ColumnStyle(SizeType.Percent, 73.65854!))

    TableLayoutPanel3.ColumnStyles.Add(New ColumnStyle(SizeType.Absolute, 85.0!))

    Controls.Add(TableLayoutPanel3)

Create a button btnAddRow to add rows on each click

     Private Sub btnAddRow_Click(sender As System.Object, e As System.EventArgs) Handles btnAddRow.Click

          TableLayoutPanel3.GrowStyle = TableLayoutPanelGrowStyle.AddRows

          TableLayoutPanel3.RowStyles.Add(New RowStyle(SizeType.Absolute, 20))

          TableLayoutPanel3.SuspendLayout()

          TableLayoutPanel3.RowCount += 1

          Dim tb1 As New TextBox()

          Dim tb2 As New TextBox()

          Dim tb3 As New TextBox()

          TableLayoutPanel3.Controls.Add(tb1 , 0, TableLayoutPanel3.RowCount - 1)

          TableLayoutPanel3.Controls.Add(tb2, 1, TableLayoutPanel3.RowCount - 1)

          TableLayoutPanel3.Controls.Add(tb3, 2, TableLayoutPanel3.RowCount - 1)

          TableLayoutPanel3.ResumeLayout()

          tb1.Focus()

 End Sub

let res = /^[a-zA-Z]+$/.test('sfjd');
console.log(res);

Note: If you have any punctuation marks or anything, those are all invalid too. Dashes and underscores are invalid. \w covers a-zA-Z and some other word characters. It all depends on what you need specifically.

way of getting home directory of current user is

String currentUsersHomeDir = System.getProperty("user.home");

and to append path separator

String otherFolder = currentUsersHomeDir + File.separator + "other";

File.separator

The system-dependent default name-separator character, represented as a string for convenience. This string contains a single character, namely separatorChar.

I know I'm late to this party, but for an existing table, try:

ALTER table TABLE_NAME
ADD CONSTRAINT [name of your PK, e.g. PK_TableName] PRIMARY KEY CLUSTERED (column1, column2, etc.)

The most basic way to iterate over a hash is as follows:

hash.each do |key, value|
  puts key
  puts value
end

I would like to mention one case where you must use std::move() otherwise it will give an error. Case: If the return type of the function differs from the type of the local variable.

class Base { ... };
class Derived : public Base { ... };
...
std::unique_ptr<Base> Foo() {
     std::unique_ptr<Derived> derived(new Derived());
     return std::move(derived); //std::move() must
}

1. Launch Run, then type in the Open drop down window: regedit

2. Navigate to, just like in Window's Explorer:
   HKEY_CURRENT_USER\Software\SimonTatham

3. Right click on 'SimonTatham' key (directory icon), select Export
   Give the file a name (say) putty.reg and save it to your location for
   later use.
4. Close Registry Editor.

Done.

You may use:

if ( frm.product.value=="F" ){
    var $select_box = $('[name=val]');
    $select_box.find('[value=A],[value=C]').remove(); 
}

Update: If you modify your select box a bit to this

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

the non-jQuery solution would be this

if ( frm.product.value=="F" ){
    var elem = document.getElementById('A');
    elem.parentNode.removeChild(elem);
    var elem = document.getElementById('C');
    elem.parentNode.removeChild(elem);
}

If you wish to use 2 subdomains to other ports, you can use Minecraft's proxy server (it means BungeeCord, Waterfall, Travertine...), and bind subdomain to specifiend in config.yml server. To do that you have to setup your servers in BungeeCord's config:

servers:
  pvp:
    motd: 'A Minecraft Server PVP'
    address: localhost:25566
    restricted: false
  skyblock:
    motd: 'A Minecraft Server SkyBlock'
    address: localhost:25567
    restricted: false

Remember! Ports must be diffrent than default Minecraft's port (it means 25565), because we will use this port to our proxy. sub1.domain.com and sub2.domain.com we have to bind to server where you have these servers. Now, we have to bind subdomains in your Bungee server:

listeners:
    forced_hosts:
      sub1.domain.com: pvp
      sub2.domain.com: skyblock
      domain.com: pvp // You can bind other domains to same servers.

Remember to change force_default_server to true, and change host to 0.0.0.0:25565 Example of BungeeCord's config.yml with some servers: https://pastebin.com/tA9ktZ6f Now you can connect to your pvp server on sub1.domain.com and connect to skyblock on sub2.domain.com. Don't worry, BungeeCord takes only 0,5GB of RAM for 500 players.

Thanks this helped. It was a little tricky getting the USB debugging option enabled on the Samsung G3 after the update.

See below Instructions on Samsung G3 Jellybean

1. Settings
2. Click --> About the phone
3. Tap on the build number
4. “You are now 4 steps away from being a developer.” Keep tapping until it says “You are now a developer.”
5. Go back to Setting-->System --> Developer option: Enable USB Debugging

Sure, a very similar question was asked before. Set the controller for ajax requests:

public ActionResult Show()
{
    if (Request.IsAjaxRequest()) 
    {
        return PartialView("Your_partial_view", new Model());
    }
    else 
    {
        return View();
    }
}

Set the action link as wanted:

@Ajax.ActionLink("Show", 
                 "Show", 
                 null, 
                 new AjaxOptions { HttpMethod = "GET", 
                 InsertionMode = InsertionMode.Replace, 
                 UpdateTargetId = "dialog_window_id", 
                 OnComplete = "your_js_function();" })

Note that I'm using Razor view engine, and that your AjaxOptions may vary depending on what you want. Finally display it on a modal window. The jQuery UI dialog is suggested.

explode('.', 'a.b');

str_replace will do the trick thusly

$new_str = str_replace(' ', '', $old_str);

If you want it short this should work.

Use FirstOrDefault or a foreach loop as already mentioned. Manually fetching an enumerator and calling Current should be avoided. foreach will dispose your enumerator for you if it implements IDisposable. When calling MoveNext and Current you have to dispose it manually (if aplicable).

(I thought it might be helpful to lay out the ideas very simply here to summarize the good material posted by @doug, & linked by @duffymo; +1 to each,btw.)

?order tells you which element of the original vector needs to be put first, second, etc., so as to sort the original vector, whereas ?rank tell you which element has the lowest, second lowest, etc., value. For example:

> a <- c(45, 50, 10, 96)
> order(a)  
[1] 3 1 2 4  
> rank(a)  
[1] 2 3 1 4  

So order(a) is saying, 'put the third element first when you sort... ', whereas rank(a) is saying, 'the first element is the second lowest... '. (Note that they both agree on which element is lowest, etc.; they just present the information differently.) Thus we see that we can use order() to sort, but we can't use rank() that way:

> a[order(a)]  
[1] 10 45 50 96  
> sort(a)  
[1] 10 45 50 96  
> a[rank(a)]  
[1] 50 10 45 96  

In general, order() will not equal rank() unless the vector has been sorted already:

> b <- sort(a)  
> order(b)==rank(b)  
[1] TRUE TRUE TRUE TRUE  

Also, since order() is (essentially) operating over ranks of the data, you could compose them without affecting the information, but the other way around produces gibberish:

> order(rank(a))==order(a)  
[1] TRUE TRUE TRUE TRUE  
> rank(order(a))==rank(a)  
[1] FALSE FALSE FALSE  TRUE
