Programs & Examples On #Xerces

I guess there is one question you need to answer:

Does there exist a xerces*.jar that everything in your application can live with?

If not you are basically screwed and would have to use something like OSGI, which allows you to have different versions of a library loaded at the same time. Be warned that it basically replaces jar version issues with classloader issues ...

If there exists such a version you could make your repository return that version for all kinds of dependencies. It's an ugly hack and would end up with the same xerces implementation in your classpath multiple times but better than having multiple different versions of xerces.

You could exclude every dependency to xerces and add one to the version you want to use.

I wonder if you can write some kind of version resolution strategy as a plugin for maven. This would probably the nicest solution but if at all feasible needs some research and coding.

For the version contained in your runtime environment, you'll have to make sure it either gets removed from the application classpath or the application jars get considered first for classloading before the lib folder of the server get considered.

So to wrap it up: It's a mess and that won't change.

First clear the temporary files in Windows system, then restart your system.

Out of the box JQuery UI offers this solution:

$( function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height: "auto",
      width: 400,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  } );

HTML

<div id="dialog-confirm" title="Empty the recycle bin?">
  <p><span class="ui-icon ui-icon-alert" style="float:left; margin:12px 12px 20px 0;">
 </span>These items will be permanently deleted and cannot be recovered. Are you sure?</p>
</div>

You can further customize this by providing a name for the JQuery function and passing the text/title you want displayed as a parameter.

Had the same problem, it was indeed caused by weblogic stupidly using its own opensaml implementation. To solve it, you have to tell it to load classes from WEB-INF/lib for this package in weblogic.xml:

    <prefer-application-packages>
        <package-name>org.opensaml.*</package-name>
    </prefer-application-packages>

maybe <prefer-web-inf-classes>true</prefer-web-inf-classes> would work too.

Overview of Scanner.hasNextXXX methods

java.util.Scanner has many hasNextXXX methods that can be used to validate input. Here's a brief overview of all of them:

• hasNext() - does it have any token at all?
• hasNextLine() - does it have another line of input?
• For Java primitives
  • hasNextInt() - does it have a token that can be parsed into an int?
  • Also available are hasNextDouble(), hasNextFloat(), hasNextByte(), hasNextShort(), hasNextLong(), and hasNextBoolean()
  • As bonus, there's also hasNextBigInteger() and hasNextBigDecimal()
  • The integral types also has overloads to specify radix (for e.g. hexadecimal)
• Regular expression-based
  • hasNext(String pattern)
  • hasNext(Pattern pattern) is the Pattern.compile overload

Scanner is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern), which lets you define what pattern separates your tokens. There are also find and skip methods that ignores delimiters.

The following discussion will keep the regex as simple as possible, so the focus remains on Scanner.

Example 1: Validating positive ints

Here's a simple example of using hasNextInt() to validate positive int from the input.

Scanner sc = new Scanner(System.in);
int number;
do {
    System.out.println("Please enter a positive number!");
    while (!sc.hasNextInt()) {
        System.out.println("That's not a number!");
        sc.next(); // this is important!
    }
    number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);

Here's an example session:

Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5

Note how much easier Scanner.hasNextInt() is to use compared to the more verbose try/catch Integer.parseInt/NumberFormatException combo. By contract, a Scanner guarantees that if it hasNextInt(), then nextInt() will peacefully give you that int, and will not throw any NumberFormatException/InputMismatchException/NoSuchElementException.

Related questions

• How to use Scanner to accept only valid int as input
• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Example 2: Multiple hasNextXXX on the same token

Note that the snippet above contains a sc.next() statement to advance the Scanner until it hasNextInt(). It's important to realize that none of the hasNextXXX methods advance the Scanner past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!

This has two consequences:

• If you need to skip the "garbage" input that fails your hasNextXXX test, then you need to advance the Scanner one way or another (e.g. next(), nextLine(), skip, etc).
• If one hasNextXXX test fails, you can still test if it perhaps hasNextYYY!

Here's an example of performing multiple hasNextXXX tests.

Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
    System.out.println(
        sc.hasNextInt() ? "(int) " + sc.nextInt() :
        sc.hasNextLong() ? "(long) " + sc.nextLong() :  
        sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
        sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
        "(String) " + sc.next()
    );
}

Here's an example session:

5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit

Note that the order of the tests matters. If a Scanner hasNextInt(), then it also hasNextLong(), but it's not necessarily true the other way around. More often than not you'd want to do the more specific test before the more general test.

Example 3 : Validating vowels

Scanner has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.

Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
    System.out.println("That's not a vowel!");
    sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);

Here's an example session:

Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e

In regex, as a Java string literal, the pattern "[aeiou]" is what is called a "character class"; it matches any of the letters a, e, i, o, u. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner.

Example 4: Using two Scanner at once

Sometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner, where the second Scanner takes the nextLine() from the first Scanner as input. Here's an example:

Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
    Scanner lineSc = new Scanner(sc.nextLine());
    int sum = 0;
    while (lineSc.hasNextInt()) {
        sum += lineSc.nextInt();
    }
    System.out.println("Sum is " + sum);
}

Here's an example session:

Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit

In addition to Scanner(String) constructor, there's also Scanner(java.io.File) among others.

Summary

• Scanner provides a rich set of features, such as hasNextXXX methods for validation.
• Proper usage of hasNextXXX/nextXXX in combination means that a Scanner will NEVER throw an InputMismatchException/NoSuchElementException.
• Always remember that hasNextXXX does not advance the Scanner past any input.
• Don't be shy to create multiple Scanner if necessary. Two simple Scanner is often better than one overly complex Scanner.
• Finally, even if you don't have any plans to use the advanced regex features, do keep in mind which methods are regex-based and which aren't. Any Scanner method that takes a String pattern argument is regex-based.
  • Tip: an easy way to turn any String into a literal pattern is to Pattern.quote it.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

Try using a wide viewport:

 webview.getSettings().setUseWideViewPort(true);

Run:

git remote prune origin

Deletes all stale tracking branches which have already been removed at origin but are still locally available in remotes/origin.

git gc --auto

'G arbage C ollection' - runs housekeeping tasks (compresses revisions, removes loose/inaccessible objects). The --auto flag first determines whether any work is required, and exits without doing anything if not.

I think pi has ssh server enabled by default. Mine have always worked out of the box. Depends which operating system version maybe.

Most of the time when it fails for me it is because the ip address has been changed. Perhaps you are pinging something else now? Also sometimes they just refuse to connect and need a restart.

As this is the top post if you google for MySQL high CPU usage or load, I'll add an additional answer:

On the 1st of July 2012, a leap second was added to the current UTC-time to compensate for the slowing rotation of the earth due to the tides. When running ntp (or ntpd) this second was added to your computer's/server's clock. MySQLd does not seem to like this extra second on some OS'es, and yields a high CPU load. The quick fix is (as root):

$ /etc/init.d/ntpd stop
$ date -s "`date`"
$ /etc/init.d/ntpd start

I have just noticed that Bjarne Stroustrup labels % as the remainder operator, not the modulo operator.

I would bet that this is its formal name in the ANSI C & C++ specifications, and that abuse of terminology has crept in. Does anyone know this for a fact?

But if this is the case then C's fmodf() function (and probably others) are very misleading. they should be labelled fremf(), etc

You are looking for:

ord()

By the time you say rate = lambda whatever... you've defeated the point of lambda and should just define a function. But, if you want a lambda, you can use 'and' and 'or'

lambda(T): (T>200) and (200*exp(-T)) or (400*exp(-T))

I didn't look very hard but I didn't see anyone who used regex for this problem.

I interpreted the question as "given a path, return the basename without the extension."

e.g.

"path/to/file.json" => "file"

"path/to/my.file.json" => "my.file"

In Python 2.7, where we still live without pathlib...

def get_file_name_prefix(file_path):
    basename = os.path.basename(file_path)

    file_name_prefix_match = re.compile(r"^(?P<file_name_pre fix>.*)\..*$").match(basename)

    if file_name_prefix_match is None:
        return file_name
    else:
        return file_name_prefix_match.group("file_name_prefix")

get_file_name_prefix("path/to/file.json")
>> file

get_file_name_prefix("path/to/my.file.json")
>> my.file

get_file_name_prefix("path/to/no_extension")
>> no_extension

In controller you can use MvcHtmlString

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string rawHtml = "<HTML></HTML>";
        ViewBag.EncodedHtml = MvcHtmlString.Create(rawHtml);
        return View();
    }
}

In your View you can simply use that dynamic property which you set in your Controller like below

<div>
        @ViewBag.EncodedHtml
</div>

From the relevant Git documentation:

Patterns which are specific to a particular repository but which do not need to be shared with other related repositories (e.g., auxiliary files that live inside the repository but are specific to one user's workflow) should go into the $GIT_DIR/info/exclude file.

The .git/info/exclude file has the same format as any .gitignore file. Another option is to set core.excludesFile to the name of a file containing global patterns.

Note, if you already have unstaged changes you must run the following after editing your ignore-patterns:

git update-index --assume-unchanged <file-list>

Note on $GIT_DIR: This is a notation used all over the git manual simply to indicate the path to the git repository. If the environment variable is set, then it will override the location of whichever repo you're in, which probably isn't what you want.

Edit: Another way is to use:

git update-index --skip-worktree <file-list>

Reverse it by:

git update-index --no-skip-worktree <file-list>

You can use a redirect to that action :

redirect_to your_controller_action_url

Lucida Sans Typewriter

This is a jQuery plugin which sets the equal height for all elements on the same row(by checking the element's offset.top). So if your jQuery array contains elements from more than one row(different offset.top), each row will have a separated height, based on element with maximum height on that row.

jQuery.fn.setEqualHeight = function(){

var $elements = [], max_height = [];

jQuery(this).css( 'min-height', 0 );

// GROUP ELEMENTS WHICH ARE ON THE SAME ROW
this.each(function(index, el){ 

    var offset_top = jQuery(el).offset().top;
    var el_height = jQuery(el).css('height');

    if( typeof $elements[offset_top] == "undefined" ){
        $elements[offset_top] = jQuery();
        max_height[offset_top] = 0;
    }

    $elements[offset_top] = $elements[offset_top].add( jQuery(el) );

    if( parseInt(el_height) > parseInt(max_height[offset_top]) )
        max_height[offset_top] = el_height;

});

// CHANGE ELEMENTS HEIGHT
for( var offset_top in $elements ){

    if( jQuery($elements[offset_top]).length > 1 )
        jQuery($elements[offset_top]).css( 'min-height', max_height[offset_top] );

}

};

Simply you can do it easy... You just need to get the context of your activity, here, from your View.

//Create intent getting the context of your View and the class where you want to go
Intent intent = new Intent(view.getContext(), YourClass.class);

//start the activity from the view/context
view.getContext().startActivity(intent); //If you are inside activity, otherwise pass context to this funtion

Remember that you need to modify AndroidManifest.xml and place the activity...

<activity
        android:name=".YourClass"
        android:label="Label for your activity"></activity>

Based on @L.B.'s solution, the (typed as Object rather than Anonymous) VB code is

Dim oJson As Object = JsonConvert.DeserializeObject(File.ReadAllText(MyFilePath))

I should mention that this is quick and useful for constructing HTTP call content where the type isn't required. And using Object rather than Anonymous means you can maintain Option Strict On in your Visual Studio environment - I hate turning that off.

A wrapper class java.lang.Long can store 10 digit easily.

   Long phoneNumber = 1234567890;

It can store more than that also.

Documentation:

public final class Long extends Number implements Comparable<Long> {
    /**
     * A constant holding the minimum value a {@code long} can
     * have, -2<sup>63</sup>.
     */
    @Native public static final long MIN_VALUE = 0x8000000000000000L;

    /**
     * A constant holding the maximum value a {@code long} can
     * have, 2<sup>63</sup>-1.
     */
    @Native public static final long MAX_VALUE = 0x7fffffffffffffffL;
}

This means it can store values of range 9,223,372,036,854,775,807 to -9,223,372,036,854,775,808.

CDATA is a sequence of characters from the document character set and may include character entities. User agents should interpret attribute values as follows: Replace character entities with characters,

Ignore line feeds,

Replace each carriage return or tab with a single space.

It really doesn't matter.
If you feed .c to a c++ compiler it will compile as cpp, .cc/.cxx is just an alternative to .cpp used by some compilers.

.hpp is an attempt to distinguish header files where there are significant c and c++ differences. A common usage is for the .hpp to have the necessary cpp wrappers or namespace and then include the .h in order to expose a c library to both c and c++.

I try to avoid using the "SELECT * " option and just pull what data I want or need. The code below is what I use, you may cull out or add columns and aliases per your needs.

I also us "IIF" (instant if) to replace binary 0 or 1 with a yes or no. It just makes it easier to read for the non-techie that may want this info.

Here is what I use:

SELECT 
    name AS 'User'
  , PRINCIPAL_ID
  , type AS 'User Type'
  , type_desc AS 'Login Type'
  , CAST(create_date AS DATE) AS 'Date Created' 
  , default_database_name AS 'Database Name'
  , IIF(is_fixed_role LIKE 0, 'No', 'Yes') AS 'Is Active'
FROM master.sys.server_principals
WHERE type LIKE 's' OR type LIKE 'u'
ORDER BY [User], [Database Name]; 
GO

Hope this helps.

This just happened to me and after trying everything else, I just happened to notice on the error message that the app pool was set to .Net 1.1. I upgraded the app to 2.0, converted to web application, but never changed the app pool:

Version Information: Microsoft .NET Framework Version:1.1.4322.2490; ASP.NET Version:1.1.4322.2494

grep -e apple your_site_root/**/*.* -s -l | xargs sed -i "" "s|apple|orage|"

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

The solution is simple.

After installing Node, you should restart your VScode and run npm install command.

I want to select the text of a string that is located after the occurrence of substring

You could use:

substring-after($string,$match)

If you want a subtring of the above with some length then use:

substring(substring-after($string,$match),1,$length)

But problems begin if there is no ocurrence of the matching substring... So, if you want a substring with specific length located after the occurrence of a substring, or from the whole string if there is no match, you could use:

substring(substring-after($string,substring-before($string,$match)),
          string-length($match) * contains($string,$match) + 1,
          $length) 

Per @l3x, it depends.

There are clearly two sets of general situations where the correct answer can be different, along with a third which is not as general:

a) You are a user sending private mails:

Very few modern email systems implement case sensitivity, so you are probably fine to ignore case and choose whatever case you feel like using. There is no guarantee that all your mails will be delivered - but so few mails would be negatively affected that you should not worry about it.

b) You are developing mail software:

See RFC5321 2.4 excerpt at the bottom.

When you are developing mail software, you want to be RFC-compliant. You can make your own users' email addresses case insensitive if you want to (and you probably should). But in order to be RFC compliant, you MUST treat outside addresses as case sensitive.

c) Managing business-owned lists of email addresses as an employee:

It is possible that the same email recipient is added to a list more than once - but using different case. In this situation though the addresses are technically different, it might result in a recipient receiving duplicate emails. How you treat this situation is similar to situation a) in that you are probably fine to treat them as duplicates and to remove a duplicate entry. It is better to treat these as special cases however, by sending a "reminder" mail to both addresses to ask them if the case of the email address is accurate.

From a legal standpoint, if you remove a duplicate without acknowledgement/permission from both addresses, you can be held responsible for leaking private information/authentication to an unauthorised address simply because two actually-separate recipients have the same address with different cases.

Excerpt from RFC5321 2.4:

The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged.

Must check whether incoming access to port 3306 is block or not by the firewall.

toast is a bad idea, it's far too "complex" to print the value of a variable. use log or s.o.p, and as drawnonward already said, their output goes to logcat. it only makes sense if you want to expose this information to the end-user...

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

Let me clarify two points here :

• Firstly non-default argument should not follow the default argument, it means you can't define (a = 'b',c) in function. The correct order of defining parameter in function are :
• positional parameter or non-default parameter i.e (a,b,c)
• keyword parameter or default parameter i.e (a = 'b',r= 'j')
• keyword-only parameter i.e (*args)
• var-keyword parameter i.e (**kwargs)

def example(a, b, c=None, r="w" , d=[], *ae, **ab):

(a,b) are positional parameter

(c=none) is optional parameter

(r="w") is keyword parameter

(d=[]) is list parameter

(*ae) is keyword-only

(*ab) is var-keyword parameter

so first re-arrange your parameters

• now the second thing is you have to define len1 when you are doing hgt=len1 the len1 argument is not defined when default values are saved, Python computes and saves default values when you define the function len1 is not defined, does not exist when this happens (it exists only when the function is executed)

so second remove this "len1 = hgt" it's not allowed in python.

keep in mind the difference between argument and parameters.

I think what you want requires an extra wrapper div.

#map {_x000D_
    float: left; _x000D_

If a control is readonly it cannot be edited, but its content (if any) is still included with the submission.

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

use only org.hibernate.dialect.OracleDialect Remove 10g,9 etc.

Although the following line is taken from a windows batch script, the command should be quite similar:

psql -U username -h localhost -d postgres -c "DROP DATABASE \"$DATABASE\";"

This command is used to clear the whole database, by actually dropping it. The $DATABASE (in Windows should be %DATABASE%) in the command is a windows style environment variable that evaluates to the database name. You will need to substitute that by your development_db_name.

I created a PyPI module for this reason:

pip install screeninfo

The code:

from screeninfo import get_monitors
for m in get_monitors():
    print(str(m))

Result:

monitor(1920x1080+1920+0)
monitor(1920x1080+0+0)

It supports multi monitor environments. Its goal is to be cross platform; for now it supports Cygwin and X11 but pull requests are totally welcome.

another option is rlang::is_empty (useful if you're working in the tidyverse)

The rlang namespace does not seem to be attached when attaching the tidyverse via library(tidyverse) - in this case you use purrr::is_empty, which is just imported from the rlang package.

By the way, rlang::is_empty uses user Gavin's approach.

rlang::is_empty(which(1:3 == 5))
#> [1] TRUE

You've tagged this SQL Server 2008 but future visitors to this question (using SQL Server 2016+) will likely want to know about STRING_SPLIT.

With this new builtin function you can now just use

SELECT TRY_CAST(value AS INT)
FROM   STRING_SPLIT ('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15', ',') 

Some restrictions of this function and some promising results of performance testing are in this blog post by Aaron Bertrand.

You could just use underscore library.

Install it:

   npm install underscore --save
   npm install @types/underscore --save-dev

Import it

   import _ = require('underscore');

Use it

    var x = _.filter(
      [{ "id": 1 }, { "id": -2 }, { "id": 3 }],
      myObj => myObj.id < 0)
    );

Why not use the html5 date control as it is, with other attributes that allows it work ok on browsers that support date type and still works on other browsers like firefox that is yet to support date type

<input type="date" name="input1" placeholder="YYYY-MM-DD" required pattern="[0-9]{4}-[0-9]{2}-[0-9]{2}" title="Enter a date in this formart YYYY-MM-DD"/>

Piggy backing on @MikkaS answer for Mongo Client v3.x, I just needed the async / await format, which looks slightly modified as this:

const myFunc = async () => {

     // Prepping here...


    // Connect
    let client = await MongoClient.connect('mongodb://localhost');
    let db = await client.db();

    // Run the query
    let cursor = await db.collection('customers').find({});

    // Do whatever you want on the result.
}

There's always a goto statement, but I would recommend nesting an if with an inverse of the breaking condition.

Had the same question and solved it the following way:

Start situation:

FrigoShare (root)
|-Modules:    frigoshare,   frigoShare-backend

Target: want to add a module named dataformats

1. Add a new module (e.g.: Java Library)

2. Make sure your settings.gradle look like this (normally automatically):

   include ':frigoshare', ':frigoShare-backend', ':dataformats'

3. Make sure (manually) that the build.gradle files of the modules that need to use your library have the following dependency:

   dependencies { ... compile project(':dataformats') }

I spent measurements (100000 iterations), what fastest way to glue an associative array?

Objective: To obtain a line of 1,000 items, in this format: "key:value,key2:value2"

We have array (for example):

$array = [
    'test0' => 344,
    'test1' => 235,
    'test2' => 876,
    ...
];

Test number one:

Use http_build_query and str_replace:

str_replace('=', ':', http_build_query($array, null, ','));

Average time to implode 1000 elements: 0.00012930955084904

Test number two:

Use array_map and implode:

implode(',', array_map(
        function ($v, $k) {
            return $k.':'.$v;
        },
        $array,
        array_keys($array)
    ));

Average time to implode 1000 elements: 0.0004890081976675

Test number three:

Use array_walk and implode:

array_walk($array,
        function (&$v, $k) {
            $v = $k.':'.$v;
        }
    );
implode(',', $array);

Average time to implode 1000 elements: 0.0003874126245348

Test number four:

Use foreach:

    $str = '';
    foreach($array as $key=>$item) {
        $str .= $key.':'.$item.',';
    }
    rtrim($str, ',');

Average time to implode 1000 elements: 0.00026632803902445

I can conclude that the best way to glue the array - use http_build_query and str_replace

If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.

First of all, where you're going wrong is the offset.

It should look more like this...

set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%

If the date was Tue 12/02/2013 then it would display it as 2013/02/12.

To remove the slashes, the code would look more like

set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%

which would output 20130212

And a hint for doing it in the future, if mydate equals something like %date:~10,4%%date:~7,2% or the like, you probably forgot a tilde (~).

You can use also in the php file like this

<?php ini_set('upload_max_filesize', '200M'); ?>

something like this ? :

DataTable dt = ...
DataView dv = new DataView(dt);
dv.RowFilter = "(EmpName != 'abc' or EmpName != 'xyz') and (EmpID = 5)"

Is it what you are searching for?

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

The issue is that you are trying to have multiple statements in an if without using {}. What you currently have is interpreted like:

if( choice==5 )
{
    System.out.println( ... );
}
break;
else
{
    //...
}

You really want:

if( choice==5 )
{
    System.out.println( ... );
    break;
}
else
{
    //...
}

Also, as Farce has stated, it would be better to use else if for all the conditions instead of if because if choice==1, it will still go through and check if choice==5, which would fail, and it will still go into your else block.

if( choice==1 )
    //...
else if( choice==2 )
    //...
else if( choice==3 )
    //...
else if( choice==4 )
    //...
else if( choice==5 )
{
    //...
}
else
    //...

A more elegant solution would be using a switch statement. However, break only breaks from the most inner "block" unless you use labels. So you want to label your loop and break from that if the case is 5:

LOOP:
for(;;)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch( choice )
    {
        case 1:
            playGame();
            break;
        case 2:
            loadGame();
            break;
        case 2:
            options();
            break;
        case 4:
            credits();
            break;
        case 5:
            System.out.println("End of Game\n Thank you for playing with us!");
            break LOOP;
        default:
            System.out.println( ... );
    }
}

Instead of labeling the loop, you could also use a flag to tell the loop to stop.

bool finished = false;
while( !finished )
{
    switch( choice )
    {
        // ...
        case 5:
            System.out.println( ... )
            finished = true;
            break;
        // ...
    }
}

One solution can be using pool of clients like the following:

const { Pool } = require('pg');
var config = {
    user: 'foo', 
    database: 'my_db', 
    password: 'secret', 
    host: 'localhost', 
    port: 5432, 
    max: 10, // max number of clients in the pool
    idleTimeoutMillis: 30000
};
const pool = new Pool(config);
pool.on('error', function (err, client) {
    console.error('idle client error', err.message, err.stack);
});
pool.query('SELECT $1::int AS number', ['2'], function(err, res) {
    if(err) {
        return console.error('error running query', err);
    }
    console.log('number:', res.rows[0].number);
});

I understand that your main problem is that you need to calculate d=b-a but your arrays have different sizes. There is no need for an intermediate padded c

You can solve this without padding:

import numpy as np

a = np.array([[ 1.,  1.,  1.,  1.,  1.],
              [ 1.,  1.,  1.,  1.,  1.],
              [ 1.,  1.,  1.,  1.,  1.]])

b = np.array([[ 3.,  3.,  3.,  3.,  3.,  3.],
              [ 3.,  3.,  3.,  3.,  3.,  3.],
              [ 3.,  3.,  3.,  3.,  3.,  3.],
              [ 3.,  3.,  3.,  3.,  3.,  3.]])

d = b.copy()
d[:a.shape[0],:a.shape[1]] -=  a

print d

Output:

[[ 2.  2.  2.  2.  2.  3.]
 [ 2.  2.  2.  2.  2.  3.]
 [ 2.  2.  2.  2.  2.  3.]
 [ 3.  3.  3.  3.  3.  3.]]

Best way to do is use the extension(pflannery.vscode-versionlens) in vscode.

this checks for all satisfy and checks for best fit.

i had lot of issues with updating and keeping my app functioining unitll i let verbose lense did the check and then i run

npm i

to install newly suggested dependencies.

Try this one it will work

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.add("Nokia");
     adapter.notifyDataSetChanged();
  }
}

Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.

Problem with all proposed solutions is that it will scan and apply the filtering function twice. I'd make a simple small function like this:

def split_into_two_lists(lst, f):
    a = []
    b = []
    for elem in lst:
        if f(elem):
            a.append(elem)
        else:
            b.append(elem)
    return a, b

That way you are not processing anything twice and also are not repeating code.

This is more Effective way to count frequency of characters in a string

public class demo {
    public static void main(String[] args) {
        String s = "babdcwertyuiuygf";
        Map<Character, Integer> map = new TreeMap<>();
        s.chars().forEach(e->map.put((char)e, map.getOrDefault((char)e, 0) + 1));
        StringBuffer myValue = new StringBuffer();
        String myMapKeyValue = "";
        for (Map.Entry<Character, Integer> entry : map.entrySet()) {
            myMapKeyValue = Character.toString(entry.getKey()).concat(
                Integer.toString(entry.getValue()));
            myValue.append(myMapKeyValue);
        }
        System.out.println(myValue);
    }
}

It's better to use $(window).scroll() rather than $('#Eframe').on("mousewheel")

$('#Eframe').on("mousewheel") will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.

$(window).scroll(function(){
    var scrollPos = $(document).scrollTop();
    console.log(scrollPos);
});

If #Eframe is an element with overflow:scroll on it and you want it's scroll position. I think this should work (I haven't tested it though).

$('#Eframe').scroll(function(){
    var scrollPos = $('#Eframe').scrollTop();
    console.log(scrollPos);
});

Make a cmd file called sleep.cmd:

REM Usage: SLEEP Time_in_MiliSECONDS
@ECHO off
ping 1.0.0.0 -n 1 -w %1 > nul

Copy sleep.cmd to c:\windows\system32

Usage:

sleep 500

Sleeps for 0.5 seconds. Arguments in ms. Once copied to System32, can be used everywhere.

EDIT: You should also be away that if the machine isn't connected to a network (say a portable that your using in the subway), the ping trick doesn't really work anymore.

behaves as an inline-block element as it allows other images in same line i.e. inline and also we can change the width and height of the image and this is the property of a block element. Hence, provide both the features of inline and block elements.

I hope you find this helpful:

• typeof(IList<T>).IsGenericType == true
• typeof(IList<T>).GetGenericTypeDefinition() == typeof(IList<>)
• typeof(IList<int>).GetGenericArguments()[0] == typeof(int)

This is what I was looking for here:

declare -A hashmap
hashmap["key"]="value"
hashmap["key2"]="value2"
echo "${hashmap["key"]}"
for key in ${!hashmap[@]}; do echo $key; done
for value in ${hashmap[@]}; do echo $value; done
echo hashmap has ${#hashmap[@]} elements

This did not work for me with bash 4.1.5:

animals=( ["moo"]="cow" )

c="123".match(/\D/) == null #true
c="a12".match(/\D/) == null #false

If a string contains only digits it will return null

I have created a ultimate small js npm library for the base64 encode/decode conversion in Node.js.

Installation

npm install nodejs-base64-converter --save

Usage

var nodeBase64 = require('nodejs-base64-converter');

console.log(nodeBase64.encode("test text")); //dGVzdCB0ZXh0
console.log(nodeBase64.decode("dGVzdCB0ZXh0")); //test text

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.

set codedirectory=C:\Users\code
for /r  %codedirectory% %%i in (*.c) do 
( some GCC commands )

for (int i = 0; i < clbIncludes.Items.Count; i++)
  if (clbIncludes.GetItemChecked(i))
    // Do selected stuff
  else
    // Do unselected stuff

If the the check is in indeterminate state, this will still return true. You may want to replace

if (clbIncludes.GetItemChecked(i))

with

if (clbIncludes.GetItemCheckState(i) == CheckState.Checked)

if you want to only include actually checked items.

The DATEPART() function is used to return a single part of a date/time, such as year, month, day, hour, minute, etc.

datepart    ***Abbreviation

year        ***yy, yyyy 
quarter     ***qq, q 
month       ***mm, m 
dayofyear   ***dy, y 
day         ***dd, d 
week        ***wk, ww 
weekday     ***dw, w 
hour        ***hh 
minute      ***mi, n 
second      ***ss, s 
millisecond ***ms 
microsecond ***mcs 
nanosecond  ***ns 

Example

select *

Starting in NumPy version 1.10, we have the method stack. It can stack arrays of any dimension (all equal):

# List of arrays.
L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]

# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True

M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)

# This are all true    
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Not to necro a thread, but under the latest version of jQuery the suggested syntax is:

$( handler )

Using an anonymous function, this would look like

$(function() { ... insert code here ... });

See this link:

https://api.jquery.com/ready/

Here is pythonic way to do it. This function will allow you to loop through key-value pair in all the levels. It does not save the whole thing to the memory but rather walks through the dict as you loop through it

def recursive_items(dictionary):
    for key, value in dictionary.items():
        if type(value) is dict:
            yield (key, value)
            yield from recursive_items(value)
        else:
            yield (key, value)

a = {'a': {1: {1: 2, 3: 4}, 2: {5: 6}}}

for key, value in recursive_items(a):
    print(key, value)

Prints

a {1: {1: 2, 3: 4}, 2: {5: 6}}
1 {1: 2, 3: 4}
1 2
3 4
2 {5: 6}
5 6

This is a modified version of the solution proposed by Mr Siir. I find that adding an extension method is the best solution for reuse and simplicity in the calling method.

public static bool IsNumeric(this String s)
{
    try { double.Parse(s); return true; }
    catch (Exception) { return false; }
}

I modified the method body to fit on 2 lines and removed the unnecessary .ToString() implementation. For those not familiar with extension methods here is how to implement:

Create a class file called ExtensionMethods. Paste in this code:

using System;
using System.Collections.Generic;
using System.Text;

namespace YourNameSpaceHere
{
    public static class ExtensionMethods
    {
        public static bool IsNumeric(this String s)
        {
            try { double.Parse(s); return true; }
            catch (Exception) { return false; }
        }
    }
}

Replace YourNameSpaceHere with your actual NameSpace. Save changes. Now you can use the extension method anywhere in your app:

bool validInput = stringVariable.IsNumeric();

Note: this method will return true for integers and decimals, but will return false if the string contains a comma. If you want to accept input with commas or symbols like "$" I would suggest implementing a method to remove those characters first then test if IsNumeric.

Updated 5 September 2010

Seeing as everyone seems to get directed here for this issue, I'm adding my answer to a similar question, which contains the same code as this answer but with full background for those who are interested:

IE's document.selection.createRange doesn't include leading or trailing blank lines

To account for trailing line breaks is tricky in IE, and I haven't seen any solution that does this correctly, including any other answers to this question. It is possible, however, using the following function, which will return you the start and end of the selection (which are the same in the case of a caret) within a <textarea> or text <input>.

Note that the textarea must have focus for this function to work properly in IE. If in doubt, call the textarea's focus() method first.

function getInputSelection(el) {
    var start = 0, end = 0, normalizedValue, range,
        textInputRange, len, endRange;

    if (typeof el.selectionStart == "number" && typeof el.selectionEnd == "number") {
        start = el.selectionStart;
        end = el.selectionEnd;
    } else {
        range = document.selection.createRange();

        if (range && range.parentElement() == el) {
            len = el.value.length;
            normalizedValue = el.value.replace(/\r\n/g, "\n");

            // Create a working TextRange that lives only in the input
            textInputRange = el.createTextRange();
            textInputRange.moveToBookmark(range.getBookmark());

            // Check if the start and end of the selection are at the very end
            // of the input, since moveStart/moveEnd doesn't return what we want
            // in those cases
            endRange = el.createTextRange();
            endRange.collapse(false);

            if (textInputRange.compareEndPoints("StartToEnd", endRange) > -1) {
                start = end = len;
            } else {
                start = -textInputRange.moveStart("character", -len);
                start += normalizedValue.slice(0, start).split("\n").length - 1;

                if (textInputRange.compareEndPoints("EndToEnd", endRange) > -1) {
                    end = len;
                } else {
                    end = -textInputRange.moveEnd("character", -len);
                    end += normalizedValue.slice(0, end).split("\n").length - 1;
                }
            }
        }
    }

    return {
        start: start,
        end: end
    };
}

JavaScript with a few modifications:

function deleteRow(btn) {
  var row = btn.parentNode.parentNode;
  row.parentNode.removeChild(row);
}

And the HTML with a little difference:

    <tr>
      <td>Relationship Type</td>
      <td>Date of Birth</td>
      <td>Gender</td>

Say you train a model on a training set and then measure its performance on a test set. You think that there is still room for improvement and you try tweaking the hyper-parameters ( If the model is a Neural Network - hyper-parameters are the number of layers, or nodes in the layers ). Now you get a slightly better performance. However, when the model is subjected to another data ( not in the testing and training set ) you may not get the same level of accuracy. This is because you introduced some bias while tweaking the hyper-parameters to get better accuracy on the testing set. You basically have adapted the model and hyper-parameters to produce the best model for that particular training set.

A common solution is to split the training set further to create a validation set. Now you have

• training set
• testing set
• validation set

You proceed as before but this time you use the validation set to test the performance and tweak the hyper-parameters. More specifically, you train multiple models with various hyper-parameters on the reduced training set (i.e., the full training set minus the validation set), and you select the model that performs best on the validation set.

Once you've selected the best performing model on the validation set, you train the best model on the full training set (including the valida- tion set), and this gives you the final model.

Lastly, you evaluate this final model on the test set to get an estimate of the generalization error.

Try this:

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:view.bounds];
view.layer.masksToBounds = NO;
view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
view.layer.shadowOpacity = 0.5f;
view.layer.shadowPath = shadowPath.CGPath;

First of all: The UIBezierPath used as shadowPath is crucial. If you don't use it, you might not notice a difference at first, but the keen eye will observe a certain lag occurring during events like rotating the device and/or similar. It's an important performance tweak.

Regarding your issue specifically: The important line is view.layer.masksToBounds = NO. It disables the clipping of the view's layer's sublayers that extend further than the view's bounds.

For those wondering what the difference between masksToBounds (on the layer) and the view's own clipToBounds property is: There isn't really any. Toggling one will have an effect on the other. Just a different level of abstraction.

Swift 2.2:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.blackColor().CGColor
    layer.shadowOffset = CGSizeMake(0.0, 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.CGPath
}

Swift 3:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOffset = CGSize(width: 0.0, height: 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.cgPath
}

You should do this using jQuery.ajaxStart and jQuery.ajaxStop.

1. Create a div with your image
2. Make it visible in jQuery.ajaxStart
3. Hide it in jQuery.ajaxStop

Sample

<div id="loading" style="display:none">Your Image</div>

<script src="../../Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script>
    $(function () {
        var loading = $("#loading");
        $(document).ajaxStart(function () {
            loading.show();
        });

        $(document).ajaxStop(function () {
            loading.hide();
        });

        $("#startAjaxRequest").click(function () {
            $.ajax({
                url: "http://www.google.com",
                // ... 
            });
        });
    });
</script>

<button id="startAjaxRequest">Start</button>

You have a few possible approaches to treat path on Windows, from the most hardcoded ones (as using raw string literals or escaping backslashes) to the least ones. Here follows a few examples that will work as expected. Use what better fits your needs.

In[1]: from os.path import join, isdir

In[2]: from os import sep

In[3]: isdir(join("c:", "\\", "Users"))
Out[3]: True

In[4]: isdir(join("c:", "/", "Users"))
Out[4]: True

In[5]: isdir(join("c:", sep, "Users"))
Out[5]: True

You just need to make the siprimo and volteado methods static.

private static bool siprimo(long a)

and

private static long volteado(long a)

Instead of filtering by URL, you can also filter by HTTP header. This configuration will work for any web applications that use websockets, also if they are not using socket.io:

<VirtualHost *:80>
  ServerName www.domain2.com

  RewriteEngine On
  RewriteCond %{HTTP:Upgrade} =websocket [NC]
  RewriteRule /(.*)           ws://localhost:3001/$1 [P,L]
  RewriteCond %{HTTP:Upgrade} !=websocket [NC]
  RewriteRule /(.*)           http://localhost:3001/$1 [P,L]

  ProxyPassReverse / http://localhost:3001/
</VirtualHost>

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

For a single color line use:

list.setDivider(new ColorDrawable(0x99F10529));   //0xAARRGGBB
list.setDividerHeight(1);

It's important that DividerHeight is set after the divider, else you won't get anything.

step 2: go to WEB BROWSER title and change it to Google Chrome.

step3: Go to search menu of windows and type jupyter notebook

This will open the jupyter notebook in Google Chrome

The answers here all seem to come from a CS perspective so I want to add one from a developer perspective.

For a developer NULL is very useful. The answers here say NULL means unknown, and maybe in CS theory that's true, don't remember, it's been a while. In actual development though, at least in my experience, that happens about 1% of the time. The other 99% it is used for cases where the value is not UNKNOWN but it is KNOWN TO BE ABSENT.

For example:

• Client.LastPurchase, for a new client. It is not unknown, it is known that he hasn't made a purchase yet.

• When using an ORM with a Table per Class Hierarchy mapping, some values are just not mapped for certain classes.

• When mapping a tree structure a root will usually have Parent = NULL

• And many more...

I'm sure most developers at some point wrote WHERE value = NULL, didn't get any results, and that's how they learned about IS NULL syntax. Just look how many votes this question and the linked ones have.

SQL Databases are a tool, and they should be designed the way which is easiest for their users to understand.

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.

This might work for you (GNU sed):

sed -i -r 's/\S+//3' file

If you want to delete the white space before the 3rd field:

sed -i -r 's/(\s+)?\S+//3' file

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

Hej this is a modified version which works OK in FF @least for me and inserts at the carets position

  $.fn.extend({
  insertAtCaret: function(myValue){
  var obj;
  if( typeof this[0].name !='undefined' ) obj = this[0];
  else obj = this;

  if ($.browser.msie) {
    obj.focus();
    sel = document.selection.createRange();
    sel.text = myValue;
    obj.focus();
    }
  else if ($.browser.mozilla || $.browser.webkit) {
    var startPos = obj.selectionStart;
    var endPos = obj.selectionEnd;
    var scrollTop = obj.scrollTop;
    obj.value = obj.value.substring(0, startPos)+myValue+obj.value.substring(endPos,obj.value.length);
    obj.focus();
    obj.selectionStart = startPos + myValue.length;
    obj.selectionEnd = startPos + myValue.length;
    obj.scrollTop = scrollTop;
  } else {
    obj.value += myValue;
    obj.focus();
   }
 }
})

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

Instead of explicitly writing the class name you could use

this.getClass().getResource("/unibo/lsb/res/dice.jpg");

Take your pick:

def my_view(request):

    if request.method == 'POST':
        print request.POST.get('my_field')

        form = MyForm(request.POST)

        print form['my_field'].value()
        print form.data['my_field']

        if form.is_valid():

            print form.cleaned_data['my_field']
            print form.instance.my_field

            form.save()
            print form.instance.id  # now this one can access id/pk

Note: the field is accessed as soon as it's available.

Several other answer give the solution using MAX. In some scenarios using an agregate function is either not possilbe, or not performant.

The alternative that I use a lot is to use a correlated sub-query in the join...

SELECT
   `userName`,
   `carPrice`
FROM `users`
LEFT JOIN `cars`
ON cars.id = (
  SELECT id FROM `cars` WHERE BelongsToUser = users.id ORDER BY carPrice DESC LIMIT 1
)
WHERE `id`='4'

++i is a pre-increment; i++ is post-increment.
The downside of post-increment is that it generates an extra value; it returns a copy of the old value while modifying i. Thus, you should avoid it when possible.

You don't. The closest thing you can do is working with Maps to simulate it, or defining your own Objects to deal with.

1. this is just simple here i'm appending html table into a div at the end
2. we can achieve this or any thing with a simple concept of calling a JavaScript function when we want (here on drop.)
3. In this example you can drag & drop any number of tables, new table will be added below the last table exists in the div other wise it will be the first table in the div.
4. here we can add text between tables or we can say the section where we drop tables is editable we can type text between tables.

Thanks... :)

I also faced the same problem. Then I found a solution after a lot of searching .

The problem was that when we get the datetime object from model or form it is offset aware and if we get the time by system it is offset naive.

So what I did is I got the current time using timezone.now() and import the timezone by from django.utils import timezone and put the USE_TZ = True in your project settings file.

Why my eclipse automatically adds appcompat v7 library support whenever i create a new project

Because your target SDK is set to 15, in which the Action Bar is on by default and your minimum supported SDK is set to 10. Action Bar come out in 11, so you need a support library, Eclipse adds it for you. Reference.

You can configure project libraries in the build path of project properties.

It's not the best answer, but its also an option: since you can concatenate multiple expressions, but just the last one is rendered, you can finish your expression with "" and your variable will be hidden.

So, you could define the variable with:

{{f = forecast[day.iso]; ""}}

Try below code

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners
    android:bottomLeftRadius="30dp"
    android:bottomRightRadius="30dp"
    android:topLeftRadius="30dp"
    android:topRightRadius="30dp" />
<solid android:color="#1271BB" />

<stroke
    android:width="5dp"
    android:color="#1271BB" />

<padding
    android:bottom="1dp"
    android:left="1dp"
    android:right="1dp"
    android:top="1dp" /></shape>

They're both the same thing, a lot of framework elements expose a name property themselves, but for those that don't you can use x:name - I usually just stick with x:name because it works for everything.

Controls can expose name themselves as a Dependency Property if they want to (because they need to use that Dependency Property internally), or they can choose not to.

More details in msdn here and here:

Some WPF framework-level applications might be able to avoid any use of the x:Name attribute, because the Name dependency property as specified within the WPF namespace for several of the important base classes such as FrameworkElement/FrameworkContentElement satisfies this same purpose. There are still some common XAML and framework scenarios where code access to an element with no Name property is necessary, most notably in certain animation and storyboard support classes. For instance, you should specify x:Name on timelines and transforms created in XAML, if you intend to reference them from code.

If Name is available as a property on the class, Name and x:Name can be used interchangeably as attributes, but an error will result if both are specified on the same element.

The best way is to specify environment variables outside the docker-compose.yml file. You can use env_file setting, and define your environment file within the same line. Then doing a docker-compose up again should recreate the containers with the new environment variables.

Here is how my docker-compose.yml looks like:

services:
  web:
    env_file: variables.env

Note: docker-compose expects each line in an env file to be in VAR=VAL format. Avoid using export inside the .env file. Also, the .env file should be placed in the folder where the docker-compose command is executed.

Following @thomas-jungblut implementation in python, i did the same for Octave. If you find something wrong please let me know and i will fix+update.

Data comes from a txt file with the following rows:

1 10 1000
2 20 2500
3 25 3500
4 40 5500
5 60 6200

think about it as a very rough sample for features [number of bedrooms] [mts2] and last column [rent price] which is what we want to predict.

Here is the Octave implementation:

%
% Linear Regression with multiple variables
%

% Alpha for learning curve
alphaNum = 0.0005;

% Number of features
n = 2;

% Number of iterations for Gradient Descent algorithm
iterations = 10000

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% No need to update after here
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

DATA = load('CHANGE_WITH_DATA_FILE_PATH');

% Initial theta values
theta = ones(n + 1, 1);

% Number of training samples
m = length(DATA(:, 1));

% X with one mor column (x0 filled with '1's)
X = ones(m, 1);
for i = 1:n
  X = [X, DATA(:,i)];
endfor

% Expected data must go always in the last column  
y = DATA(:, n + 1)

function gradientDescent(x, y, theta, alphaNum, iterations)
  iterations = [];
  costs = [];

  m = length(y);

  for iteration = 1:10000
    hypothesis = x * theta;

    loss = hypothesis - y;

    % J(theta)    
    cost = sum(loss.^2) / (2 * m);

    % Save for the graphic to see if the algorithm did work
    iterations = [iterations, iteration];
    costs = [costs, cost];

    gradient = (x' * loss) / m; % /m is for the average

    theta = theta - (alphaNum * gradient);
  endfor    

  % Show final theta values
  display(theta)

  % Show J(theta) graphic evolution to check it worked, tendency must be zero
  plot(iterations, costs);

endfunction

% Execute gradient descent
gradientDescent(X, y, theta, alphaNum, iterations);

Change Your Web.Config file as below. It will act like charm.

In node <system.webServer> add below portion of code

<modules runAllManagedModulesForAllRequests="true">
  <remove name="WebDAVModule"/>
</modules>

After adding, your Web.Config will look like below

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
        <remove name="WebDAVModule"/>
    </modules>

If You're using JSX inside a function with curly braces you need to modify it to parenthesis.

Wrong Code

return this.props.todos.map((todo) => {
            <h3> {todo.author} </h3>;
        });

Correct Code

//Change Curly Brace To Paranthesis   change {} to => ()
return this.props.todos.map((todo) => (
            <h3> {todo.author} </h3>;
        ));

1. Via windows command prompt, run: pip list --outdated You will get the list of outdated packages.
2. Run: pip install [package] --upgrade It will upgrade the [package] and uninstall the previous version.

To update pip:

py -m pip install --upgrade pip

Again, this will uninstall the previous version of pip and will install the latest version of pip.

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

You can change action bar color on this way:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/green_action_bar</item>
</style>

Thats all you need for changing action bar color.

Plus if you want to change the status bar color just add the line:

 <item name="android:colorPrimaryDark">@color/green_dark_action_bar</item>

Here is a screenshot taken from developer android site to make it more clear, and here is a link to read more about customizing the color palete

I recommend using the awesome requests library:

import requests

url = 'http://maps.googleapis.com/maps/api/directions/json'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below

JSON Response Content: https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content

Use date() function to get the desired date

<?php
// set default timezone
date_default_timezone_set('UTC');

//define date and time
$strtotime = 1307595105;

// output
echo date('d M Y H:i:s',$strtotime);

// more formats
echo date('c',$strtotime); // ISO 8601 format
echo date('r',$strtotime); // RFC 2822 format
?>

Recommended online tool for strtotime to date conversion:

https://fettblog.eu/gulp-4-parallel-and-series/

Because gulp.task(name, deps, func) was replaced by gulp.task(name, gulp.{series|parallel}(deps, func)).

You are using the latest version of gulp but older code. Modify the code or downgrade.

var i = 10;
i = i / -1;

Result: -10

var i = -10;
i = i / -1;

Result: 10

If you divide by negative 1, it will always flip your number either way.

It might be worth writing your own tree wrapper based on an acyclic directed graph using the networkx library.

You can achieve this by "interpolating" the className passed from the parent component to the child component using this.props.className. Example below:

export default class ParentComponent extends React.Component {
  render(){
    return <ChildComponent className="your-modifier-class" />
  }
}

export default class ChildComponent extends React.Component {
  render(){
    return <div className={"original-class " + this.props.className}></div>
  }
}

You can run OpenSSH on Cygwin, and even install it as a Windows service.

I once used it this way to easily add backups of a Unix system - it would rsync a bunch of files onto the Windows server, and the Windows server had full tape backups.

Sidenote, if you want to concatenate one string to all of the column names, you can just use this simple code.

colnames(df) <- paste("renamed_",colnames(df),sep="")

openpyxl

# -*- coding: utf-8 -*-
import openpyxl
file = 'sample.xlsx'
wb = openpyxl.load_workbook(filename=file)
# Seleciono la Hoja
ws = wb.get_sheet_by_name('Hoja1')
# Valores a Insertar
ws['A3'] = 42
ws['A4'] = 142
# Escribirmos en el Fichero
wb.save(file)

<script type="text/javascript">
        $(document).ready(function(){

                $('.appBanner').fadeOut('slow');

        });
    </script>

or

<script type="text/javascript">
        $(document).ready(function(){

                $('.appBanner').hide();

        });
    </script>

This gem adds a Boolean class to Ruby with useful methods.

https://github.com/RISCfuture/boolean

Use:

require 'boolean'

Then your

true.is_a?(Boolean)
false.is_a?(Boolean)

will work exactly as you expect.

You can use it to transform some aggregate functions into analytic:

SELECT  MAX(date)
FROM    mytable

will return 1 row with a single maximum,

SELECT  MAX(date) OVER (ORDER BY id)
FROM    mytable

will return all rows with a running maximum.

Instead of saving it to the database, save it to a file and then call it later.

What many php apps do (like sugarcrm) is to just use var_export to echo all the data of the array to a file. This is what I use to save my configurations data:

private function saveConfig() {
    file_put_contents($this->_data['pathtocompileddata'],'<?php' . PHP_EOL . '$acs_confdata = ' . var_export($this->_data,true) . ';');        
}

I think this is a better way to save your data!

Just check if response[0] is undefined:

if(response[0] !== undefined) { ... }

If you still need to explicitly check the title, do so after the initial check:

if(response[0] !== undefined && response[0].title !== undefined){ ... }

PHP PMD (Programming Mistake Detector) and PHP CPD (Copy/Paste Detector) as the former part of PHPUnit.

For me it wasn't an outlet. I solved the problem by going to the error And reading what it said. (Also Noob..)

This was the error:

And The solution was here:

Just scroll up in the output and the error will be revealed.

import swineflu

x = swineflu.fibo()   # create an object `x` of class `fibo`, an instance of the class
x.f()                 # call the method `f()`, bound to `x`. 

Here is a good tutorial to get started with classes in Python.

I ran into this same issue, and I have come up with four total viable solutions:

1. Make the container display: flex; (this is my favorite solution)
2. Add overflow: auto; or overflow: hidden; to the container
3. Add the following CSS for the container:

.c:after {
    clear: both;
    content: "";
    display: block;
}

4. Make the following the last item inside the container:

<div style="clear: both;"></div>

dot (.) may not be considered special. I have added an OR condition to Mozfet's & Seagull's answer:

function isNumber (text) {
      reg = new RegExp('[0-9]+$');
      if(text) {
        return reg.test(text);
      }
      return false;
    }

function removeSpecial (text) {
  if(text) {
    var lower = text.toLowerCase();
    var upper = text.toUpperCase();
    var result = "";
    for(var i=0; i<lower.length; ++i) {
      if(isNumber(text[i]) || (lower[i] != upper[i]) || (lower[i].trim() === '') || (lower[i].trim() === '.')) {
        result += text[i];
      }
    }
    return result;
  }
  return '';
}

I wanted to use the styles.xml solution, but it did not work for me with activities. Turns out that instead of using android:windowEnterAnimation and android:windowExitAnimation, I need to use the activity animations like this:

<style name="ActivityAnimation.Vertical" parent="">
    <item name="android:activityOpenEnterAnimation">@anim/enter_from_bottom</item>
    <item name="android:activityOpenExitAnimation">@anim/exit_to_bottom</item>
    <item name="android:activityCloseEnterAnimation">@anim/enter_from_bottom</item>
    <item name="android:activityCloseExitAnimation">@anim/exit_to_bottom</item>
    <item name="android:windowEnterAnimation">@anim/enter_from_bottom</item>
    <item name="android:windowExitAnimation">@anim/exit_to_bottom</item>
</style>

Also, for some reason this only worked from Android 8 and above. I added the following code to my BaseActivity, to fix it for the API levels below:

override fun finish() {
    super.finish()
    setAnimationsFix()
}

/**
 * The activityCloseExitAnimation and activityCloseEnterAnimation properties do not work correctly when applied from the theme.
 * So in this fix, we retrieve them from the theme, and apply them.
 * @suppress Incorrect warning: https://stackoverflow.com/a/36263900/1395437
 */
@SuppressLint("ResourceType")
private fun setAnimationsFix() {
    // Retrieve the animations set in the theme applied to this activity in the manifest..
    var activityStyle = theme.obtainStyledAttributes(intArrayOf(attr.windowAnimationStyle))
    val windowAnimationStyleResId = activityStyle.getResourceId(0, 0)
    activityStyle.recycle()
    // Now retrieve the resource ids of the actual animations used in the animation style pointed to by
    // the window animation resource id.
    activityStyle = theme.obtainStyledAttributes(windowAnimationStyleResId, intArrayOf(activityCloseEnterAnimation, activityCloseExitAnimation))
    val activityCloseEnterAnimation = activityStyle.getResourceId(0, 0)
    val activityCloseExitAnimation = activityStyle.getResourceId(1, 0)
    activityStyle.recycle()
    overridePendingTransition(activityCloseEnterAnimation, activityCloseExitAnimation);
}

If you want to retrieve POST data:

first_name = request.form.get("firstname")

If you want to retrieve GET (query string) data:

first_name = request.args.get("firstname")

Or if you don't care/know whether the value is in the query string or in the post data:

first_name = request.values.get("firstname") 

request.values is a CombinedMultiDict that combines Dicts from request.form and request.args.

To do this for oracle sql, the syntax would be:

,SUBSTR(col,INSTR(col,'-',1,2)+1) AS new_field

for this example, I look for the second '-' and take the substring to the end

def head(iterable):
    try:
        return iter(iterable).next()
    except StopIteration:
        return None

print head(xrange(42, 1000)  # 42
print head([])               # None

BTW: I'd rework your general program flow into something like this:

lists = [
    ["first", "list"],
    ["second", "list"],
    ["third", "list"]
]

def do_something(element):
    if not element:
        return
    else:
        # do something
        pass

for li in lists:
    do_something(head(li))

(Avoiding repetition whenever possible)

Your question is vague (are you always looking for the first part?), but you can get the exact output you asked for with string.Split:

string[] substrings = a.Split(',');
b = substrings[0];
Console.WriteLine(b);

Output:

abc

Use "selrow" to get the selected row Id

var myGrid = $('#myGridId');

var selectedRowId = myGrid.jqGrid("getGridParam", 'selrow');

and then use getRowData to get the selected row at index selectedRowId.

var selectedRowData = myGrid.getRowData(selectedRowId);

If the multiselect is set to true on jqGrid, then use "selarrrow" to get list of selected rows:

var selectedRowIds = myGrid.jqGrid("getGridParam", 'selarrrow');

Use loop to iterate the list of selected rows:

var selectedRowData;

for(selectedRowIndex = 0; selectedRowIndex < selectedRowIds .length; selectedRowIds ++) {

   selectedRowData = myGrid.getRowData(selectedRowIds[selectedRowIndex]);

}

I know this is old but here's a one liner list comprehension:

data = ['word1, 23, 12','word2, 10, 19','word3, 11, 15']

[[int(item) if item.isdigit() else item for item in items.split(', ')] for items in data]

or

[int(item) if item.isdigit() else item for items in data for item in items.split(', ')]

You can do it pretty fast without creating extra arrays, so this will work even for very large arrays:

dict(izip(*([iter(a)]*2)))

If you have a generator a, even better:

dict(izip(*([a]*2)))

Here's the rundown:

iter(h)    #create an iterator from the array, no copies here
[]*2       #creates an array with two copies of the same iterator, the trick
izip(*())  #consumes the two iterators creating a tuple
dict()     #puts the tuples into key,value of the dictionary

Todo this in a single system call you can use the fs-extra npm module. After this the file will have been created as well as the directory it is to be placed in.

const fs = require('fs-extra');
const file = '/tmp/this/path/does/not/exist/file.txt'
fs.ensureFile(file, err => {
    console.log(err) // => null
});

Another way is to use ensureFileSync which will do the same thing but synchronous.

const fs = require('fs-extra');
const file = '/tmp/this/path/does/not/exist/file.txt'
fs.ensureFileSync(file)

So, having glanced quickly through some of these and other similar questions I went on a merry goose chase this afternoon trying to solve a problem with two separate programs using a file as a synchronization (and also file save) method. A bit of an unusual situation, but it definitely highlighted for me the problems with the 'check if the file is locked, then open it if it's not' approach.

The problem is this: the file can become locked between the time that you check it and the time you actually open the file. Its really hard to track down the sporadic Cannot copy the file, because it's used by another process error if you aren't looking for it too.

The basic resolution is to just try to open the file inside a catch block so that if its locked, you can try again. That way there is no elapsed time between the check and the opening, the OS does them at the same time.

The code here uses File.Copy, but it works just as well with any of the static methods of the File class: File.Open, File.ReadAllText, File.WriteAllText, etc.

/// <param name="timeout">how long to keep trying in milliseconds</param>
static void safeCopy(string src, string dst, int timeout)
{
    while (timeout > 0)
    {
        try
        {
            File.Copy(src, dst);

            //don't forget to either return from the function or break out fo the while loop
            break;
        }
        catch (IOException)
        {
            //you could do the sleep in here, but its probably a good idea to exit the error handler as soon as possible
        }
        Thread.Sleep(100);

        //if its a very long wait this will acumulate very small errors. 
        //For most things it's probably fine, but if you need precision over a long time span, consider
        //   using some sort of timer or DateTime.Now as a better alternative
        timeout -= 100;
    }
}

Another small note on parellelism: This is a synchronous method, which will block its thread both while waiting and while working on the thread. This is the simplest approach, but if the file remains locked for a long time your program may become unresponsive. Parellelism is too big a topic to go into in depth here, (and the number of ways you could set up asynchronous read/write is kind of preposterous) but here is one way it could be parellelized.

public class FileEx
{
    public static async void CopyWaitAsync(string src, string dst, int timeout, Action doWhenDone)
    {
        while (timeout > 0)
        {
            try
            {
                File.Copy(src, dst);
                doWhenDone();
                break;
            }
            catch (IOException) { }

            await Task.Delay(100);
            timeout -= 100;
        }
    }

    public static async Task<string> ReadAllTextWaitAsync(string filePath, int timeout)
    {
        while (timeout > 0)
        {
            try {
                return File.ReadAllText(filePath);
            }
            catch (IOException) { }

            await Task.Delay(100);
            timeout -= 100;
        }
        return "";
    }

    public static async void WriteAllTextWaitAsync(string filePath, string contents, int timeout)
    {
        while (timeout > 0)
        {
            try
            {
                File.WriteAllText(filePath, contents);
                return;
            }
            catch (IOException) { }

            await Task.Delay(100);
            timeout -= 100;
        }
    }
}

And here is how it could be used:

public static void Main()
{
    test_FileEx();
    Console.WriteLine("Me First!");
}    

public static async void test_FileEx()
{
    await Task.Delay(1);

    //you can do this, but it gives a compiler warning because it can potentially return immediately without finishing the copy
    //As a side note, if the file is not locked this will not return until the copy operation completes. Async functions run synchronously
    //until the first 'await'. See the documentation for async: https://msdn.microsoft.com/en-us/library/hh156513.aspx
    CopyWaitAsync("file1.txt", "file1.bat", 1000);

    //this is the normal way of using this kind of async function. Execution of the following lines will always occur AFTER the copy finishes
    await CopyWaitAsync("file1.txt", "file1.readme", 1000);
    Console.WriteLine("file1.txt copied to file1.readme");

    //The following line doesn't cause a compiler error, but it doesn't make any sense either.
    ReadAllTextWaitAsync("file1.readme", 1000);

    //To get the return value of the function, you have to use this function with the await keyword
    string text = await ReadAllTextWaitAsync("file1.readme", 1000);
    Console.WriteLine("file1.readme says: " + text);
}

//Output:
//Me First!
//file1.txt copied to file1.readme
//file1.readme says: Text to be duplicated!

var var1 = 1, var2 = 1, var3 = 1;

In this case var keyword is applicable to all the three variables.

var var1 = 1,
    var2 = 1,
    var3 = 1;

which is not equivalent to this:

var var1 = var2 = var3 = 1;

In this case behind the screens var keyword is only applicable to var1 due to variable hoisting and rest of the expression is evaluated normally so the variables var2, var3 are becoming globals

Javascript treats this code in this order:

/*
var 1 is local to the particular scope because of var keyword
var2 and var3 will become globals because they've used without var keyword
*/

var var1;   //only variable declarations will be hoisted.

var1= var2= var3 = 1; 

Make the json human readable by passing a third argument to stringify:

fs.writeFileSync('../data/phraseFreqs.json', JSON.stringify(output, null, 4));

Another method of deleting using a sub select that is better than using IN would be WHERE EXISTS

DELETE  FROM posts
WHERE   EXISTS ( SELECT  1 
                 FROM    projects
                 WHERE   projects.client_id = posts.client_id);

One reason to use this instead of the join is that a DELETE with JOIN forbids the use of LIMIT. If you wish to delete in blocks so as not to produce full table locks, you can add LIMIT use this DELETE WHERE EXISTS method.

Here is a cleaner way to show them (technically without symbolic links):

ls -1 /usr/bin/python* | grep '[2-3].[0-9]$'

Where grep filters the output of ls that that has that numeric pattern at the end ($).

Or using find:

find /usr/bin/python* ! -type l

Which shows all the different (!) of symbolic link type (-type l).

You don't need to escape it inside. You can use the | character to delimit searches.

"\"foo\"\'bar\'".replace(/("|')/g, "")

To my understanding - we do not declare a variable with a data type so by default R has set any number without L to be a numeric. If you wrote:

> x <- c(4L, 5L, 6L, 6L)
> class(x)
>"integer" #it would be correct

Example of Integer:

> x<- 2L
> print(x)

Example of Numeric (kind of like double/float from other programming languages)

> x<-3.4
> print(x)

By using itemStateChanged(ItemListener) you can track selecting and deselecting checkbox (and do whatever you want based on it):

myCheckBox.addItemListener(new ItemListener() {
    @Override
    public void itemStateChanged(ItemEvent e) {
        if(e.getStateChange() == ItemEvent.SELECTED) {//checkbox has been selected
            //do something...
        } else {//checkbox has been deselected
            //do something...
        };
    }
});

Java Swing itemStateChanged docu should help too. By using isSelected() method you can just test if actual is checkbox selected:

if(myCheckBox.isSelected()){_do_something_if_selected_}

Following will work like a charm (assuming you have div/span/table/tr/td/etc with "id"="myId")

    $("#myId").hover(function() {
        $(this).css('cursor','pointer').attr('title', 'This is a hover text.');
    }, function() {
        $(this).css('cursor','auto');
    });

As a complimentary, .css('cursor','pointer') will change the mouse pointer on hover.

if (!string.IsNullOrEmpty(Request.Form["username"])) { ... }

username is the name of the input on the submitting page. The password can be obtained the same way. If its not null or empty, it exists, then log in the user (I don't recall the exact steps for ASP.NET Membership, assuming that's what you're using).

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>> 

This is how to do it so that the printing does not run behind the prompt on the next line.

Here's the version like the ggplot2 one I gave only in base R. I copied some from @nullglob.

generate the data

carrots <- rnorm(100000,5,2)
cukes <- rnorm(50000,7,2.5)

You don't need to put it into a data frame like with ggplot2. The drawback of this method is that you have to write out a lot more of the details of the plot. The advantage is that you have control over more details of the plot.

## calculate the density - don't plot yet
densCarrot <- density(carrots)
densCuke <- density(cukes)
## calculate the range of the graph
xlim <- range(densCuke$x,densCarrot$x)
ylim <- range(0,densCuke$y, densCarrot$y)
#pick the colours
carrotCol <- rgb(1,0,0,0.2)
cukeCol <- rgb(0,0,1,0.2)
## plot the carrots and set up most of the plot parameters
plot(densCarrot, xlim = xlim, ylim = ylim, xlab = 'Lengths',
     main = 'Distribution of carrots and cucumbers', 
     panel.first = grid())
#put our density plots in
polygon(densCarrot, density = -1, col = carrotCol)
polygon(densCuke, density = -1, col = cukeCol)
## add a legend in the corner
legend('topleft',c('Carrots','Cucumbers'),
       fill = c(carrotCol, cukeCol), bty = 'n',
       border = NA)

I had a such problem too because i was using IMG tag and UL tag.

Try to apply the 'corners' plugin to elements such as $('#mydiv').corner(), $('#myspan').corner(), $('#myp').corner() but NOT for $('#img').corner()! This rule is related with adding child DIVs into specified element for emulation round-corner effect. As we know IMG element couldn't have any child elements.

I've solved this by wrapping a needed element within the div and changing IMG to DIV with background: CSS property.

Good luck!

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

Another solution is to install Xvfb, and export your display to it. ie:

disp=:8
screen=0
geom=640x480x24
exec Xvfb $disp -screen $screen $geom 2>/tmp/Xvfb.log &

Then

$ export DISPLAY=:8

$ ./example.py

Use "External data" from Excel. It can use ODBC connection to fetch data from external source: Data/Get External Data/New Database Query

That way, even if the data in the database changes, you can easily refresh.

From the current file path you could use:

os.path.join(os.path.dirname(__file__),'..','img','banner.png')

String info = "Hello \"world\"!";
info = info.replace("\"", "\\\"");

String info1 = "Hello "world!";
info1 = info1.replace('"', '\"').replace("\"", "\\\"");

For the 2nd field info1, 1st replace double quotes with an escape character.

This should work:

SELECT YEAR(STR_TO_DATE(subdateshow, '%m/%d/%Y')) FROM table;

eg:

SELECT YEAR(STR_TO_DATE('01/17/2009', '%m/%d/%Y'));  /* shows "2009" */

For using "overflow: scroll" you must set "display:block" on thead and tbody. And that messes up column widths between them. But then you can clone the thead row with Javascript and paste it in the tbody as a hidden row to keep the exact col widths.

$('.myTable thead > tr').clone().appendTo('.myTable tbody').addClass('hidden-to-set-col-widths');

http://jsfiddle.net/Julesezaar/mup0c5hk/

<table class="myTable">
    <thead>
        <tr>
            <td>Problem</td>
            <td>Solution</td>
            <td>blah</td>
            <td>derp</td>
        </tr>
    </thead>
    <tbody></tbody>
</table>
<p>
  Some text to here
</p>

The css:

table {
  background-color: #aaa;
  width: 100%;
}

thead,
tbody {
  display: block; // Necessary to use overflow: scroll
}

tbody {
  background-color: #ddd;
  height: 150px;
  overflow-y: scroll;
}

tbody tr.hidden-to-set-col-widths,
tbody tr.hidden-to-set-col-widths td {
  visibility: hidden;
  height: 0;
  line-height: 0;
  padding-top: 0;
  padding-bottom: 0;
}

td {
  padding: 3px 10px;
}

i use "Versions", quite easy, but not free .

We had trouble finding one that worked the way we wanted it to so I wrote one. I maintain the source and fix bugs as they arise plus provide free support.

I know this thread is a little bit old but I've just bumped into a similar problem (select the newest article from each category) and this is the solution I came up with :

WITH [TopCategoryArticles] AS (
    SELECT 
        [ArticleID],
        ROW_NUMBER() OVER (
            PARTITION BY [ArticleCategoryID]
            ORDER BY [ArticleDate] DESC
        ) AS [Order]
    FROM [dbo].[Articles]
)
SELECT [Articles].* 
FROM 
    [TopCategoryArticles] LEFT JOIN 
    [dbo].[Articles] ON
        [TopCategoryArticles].[ArticleID] = [Articles].[ArticleID]
WHERE [TopCategoryArticles].[Order] = 1

This is very similar to Darrel's solution but overcomes the RANK problem that might return more rows than intended.

Your problem is more easily addressed with a dictionary structure like:

x = 0
y = 1
z = 3
d = {0: 'c', 1:'d', 2:'e', 3:'f'}
mylist = [d[k] for k in [x, y, z]]

An alternative to processing the string directly would be to use a regular expression with capturing groups. This has the advantage that it makes it straightforward to imply more sophisticated constraints on the input. For example, the following splits the string into two parts, and ensures that both consist only of digits:

import java.util.regex.Pattern;
import java.util.regex.Matcher;

class SplitExample
{
    private static Pattern twopart = Pattern.compile("(\\d+)-(\\d+)");

    public static void checkString(String s)
    {
        Matcher m = twopart.matcher(s);
        if (m.matches()) {
            System.out.println(s + " matches; first part is " + m.group(1) +
                               ", second part is " + m.group(2) + ".");
        } else {
            System.out.println(s + " does not match.");
        }
    }

    public static void main(String[] args) {
        checkString("123-4567");
        checkString("foo-bar");
        checkString("123-");
        checkString("-4567");
        checkString("123-4567-890");
    }
}

As the pattern is fixed in this instance, it can be compiled in advance and stored as a static member (initialised at class load time in the example). The regular expression is:

(\d+)-(\d+)

The parentheses denote the capturing groups; the string that matched that part of the regexp can be accessed by the Match.group() method, as shown. The \d matches and single decimal digit, and the + means "match one or more of the previous expression). The - has no special meaning, so just matches that character in the input. Note that you need to double-escape the backslashes when writing this as a Java string. Some other examples:

([A-Z]+)-([A-Z]+)          // Each part consists of only capital letters 
([^-]+)-([^-]+)            // Each part consists of characters other than -
([A-Z]{2})-(\d+)           // The first part is exactly two capital letters,
                           // the second consists of digits

Due to PermGen removal some options were removed (like -XX:MaxPermSize), but options -Xms and -Xmx work in Java 8. It's possible that under Java 8 your application simply needs somewhat more memory. Try to increase -Xmx value. Alternatively you can try to switch to G1 garbage collector using -XX:+UseG1GC.

Note that if you use any option which was removed in Java 8, you will see a warning upon application start:

$ java -XX:MaxPermSize=128M -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

If you mean, you want to scroll through multiple items in your stackpanel, try putting a grid around it. By definition, a stackpanel has infinite length.

So try something like this:

   <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Width="311">
              <TextBlock Text="{Binding A}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" FontStretch="Condensed" FontSize="28" />
              <TextBlock Text="{Binding B}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
        </StackPanel>
    </Grid>

You could even make this work with a ScrollViewer

You cannot set height and width for elements with display:inline;. Use display:inline-block; instead.

From the CSS2 spec:

10.6.1 Inline, non-replaced elements

The height property does not apply. The height of the content area should be based on the font, but this specification does not specify how. A UA may, e.g., use the em-box or the maximum ascender and descender of the font. (The latter would ensure that glyphs with parts above or below the em-box still fall within the content area, but leads to differently sized boxes for different fonts; the former would ensure authors can control background styling relative to the 'line-height', but leads to glyphs painting outside their content area.)

EDIT — You're also missing a ; terminator for the height property:

<div style="display:inline; height:20px width: 70px">My Text Here</div>
<!--                                  ^^ here                       -->

So, I had to format this Epoch Timestamp date format to a legit date format in my ReactJS project. I did the following:

1. import moment from 'moment' -- given you have moment js installed via NPM, if not head to this link

2. For Example :

   If I have an Epoch date timestamp like 1595314414299, then I try this in a console to see the result -

  var dateInEpochTS = 1595314414299
  var now = moment(dateInEpochTS).format('MMM DD YYYY h:mm A');
  var now2 = moment(dateInEpochTS).format('dddd, MMMM Do, YYYY h:mm:ss A');
  console.log("NOW");
  console.log(now);
  console.log("NOW2");
  console.log(now2);

By default the @Transactional attribute works only when calling an annotated method on a reference obtained from applicationContext.

public class Bean {
  public void doStuff() {
    doTransactionStuff();
  }
  @Transactional
  public void doTransactionStuff() {

  }
}

This will open a transaction:

Bean bean = (Bean)appContext.getBean("bean");
bean.doTransactionStuff();

This will not:

Bean bean = (Bean)appContext.getBean("bean");
bean.doStuff();

Spring Reference: Using @Transactional

Note: In proxy mode (which is the default), only 'external' method calls coming in through the proxy will be intercepted. This means that 'self-invocation', i.e. a method within the target object calling some other method of the target object, won't lead to an actual transaction at runtime even if the invoked method is marked with @Transactional!

Consider the use of AspectJ mode (see below) if you expect self-invocations to be wrapped with transactions as well. In this case, there won't be a proxy in the first place; instead, the target class will be 'weaved' (i.e. its byte code will be modified) in order to turn @Transactional into runtime behavior on any kind of method.

Ultimate way to change tomcat root application. Tested on Tomcat 7 and 8.

1. Move to the tomcat webapps directory:

   Example on my machine: ~/stack/apache-tomcat/webapps

2. Rename, replace or delete ROOT folder. My advice is renaming or create a copy for backup. Example rename ROOT to RENAMED_ROOT:

   mv ROOT RENAMED_ROOT

3. Move war file with your application to tomcat webapps directory (its a directory where was old ROOT folder, on my machine: ~/stack/apache-tomcat/webapps)

War file must have a name ROOT.war. Rename your aplication if it's need: yourApplicationName.war -> ROOT.war

4. Restart tomcat. After restart your application will be a root.

Here is a way to do this. (Personally I would not do it this way, but thought it was a fun way to do it for an example)

function intDivide(numerator, denominator) {
  return parseInt((numerator/denominator).toString().split(".")[0]);
}

let x = intDivide(4,5);
let y = intDivide(5,5);
let z = intDivide(6,5);
console.log(x);
console.log(y);
console.log(z);

Style the td and th instead

td, th {
    border: 1px solid black;
}

And also to make it so there is no spacing between cells use:

table {
    border-collapse: collapse;
}

(also note, you have border-style: none; which should be border-style: solid;)

See an example here: http://jsfiddle.net/KbjNr/

src/main/resources is the "standard placement" for this.

Update: The above answers the question, but its not the best solution. Check out the other answers and the comments on this ... you would probably not shipping your own logging properties with the jar but instead leave it to the client (for example app-server, stage environment, etc) to configure the desired logging. Thus, putting it in src/test/resources is my preferred solution.

Note: Speaking of leaving the concrete log config to the client/user, you should consider replacing log4j with slf4j in your app.

If you want something quicker than profiling with Valgrind and your kernel is older and you can't use smaps, a ps with the options to show the resident set of the process (with ps -o rss,command) can give you a quick and reasonable _aproximation_ of the real amount of non-swapped memory being used.

Creating a table and copying the data in a single command:

create table T_NEW as
  select * from T;

* This will not copy PKs, FKs, Triggers, etc.

For completeness sake, the BeautifulSoup 4 version, making use of the encoding supplied by the server as well:

from bs4 import BeautifulSoup
import urllib.request

parser = 'html.parser'  # or 'lxml' (preferred) or 'html5lib', if installed
resp = urllib.request.urlopen("http://www.gpsbasecamp.com/national-parks")
soup = BeautifulSoup(resp, parser, from_encoding=resp.info().get_param('charset'))

for link in soup.find_all('a', href=True):
    print(link['href'])

or the Python 2 version:

from bs4 import BeautifulSoup
import urllib2

parser = 'html.parser'  # or 'lxml' (preferred) or 'html5lib', if installed
resp = urllib2.urlopen("http://www.gpsbasecamp.com/national-parks")
soup = BeautifulSoup(resp, parser, from_encoding=resp.info().getparam('charset'))

for link in soup.find_all('a', href=True):
    print link['href']

and a version using the requests library, which as written will work in both Python 2 and 3:

from bs4 import BeautifulSoup
from bs4.dammit import EncodingDetector
import requests

parser = 'html.parser'  # or 'lxml' (preferred) or 'html5lib', if installed
resp = requests.get("http://www.gpsbasecamp.com/national-parks")
http_encoding = resp.encoding if 'charset' in resp.headers.get('content-type', '').lower() else None
html_encoding = EncodingDetector.find_declared_encoding(resp.content, is_html=True)
encoding = html_encoding or http_encoding
soup = BeautifulSoup(resp.content, parser, from_encoding=encoding)

for link in soup.find_all('a', href=True):
    print(link['href'])

The soup.find_all('a', href=True) call finds all <a> elements that have an href attribute; elements without the attribute are skipped.

BeautifulSoup 3 stopped development in March 2012; new projects really should use BeautifulSoup 4, always.

Note that you should leave decoding the HTML from bytes to BeautifulSoup. You can inform BeautifulSoup of the characterset found in the HTTP response headers to assist in decoding, but this can be wrong and conflicting with a <meta> header info found in the HTML itself, which is why the above uses the BeautifulSoup internal class method EncodingDetector.find_declared_encoding() to make sure that such embedded encoding hints win over a misconfigured server.

With requests, the response.encoding attribute defaults to Latin-1 if the response has a text/* mimetype, even if no characterset was returned. This is consistent with the HTTP RFCs but painful when used with HTML parsing, so you should ignore that attribute when no charset is set in the Content-Type header.

Currently from the onAttach Fragment code, it is not clear if the Context is the current activity: Source Code

public void onAttach(Context context) {
    mCalled = true;
    final Activity hostActivity = mHost == null ? null : mHost.getActivity();
    if (hostActivity != null) {
        mCalled = false;
        onAttach(hostActivity);
    }
}

If you will take a look at getActivity you will see the same call

/**
 * Return the Activity this fragment is currently associated with.
 */
final public Activity getActivity() {
    return mHost == null ? null : mHost.getActivity();
}

So If you want to be sure that you are getting the Activity then use getActivity() (in onAttach in your Fragment) but don't forget to check for null because if mHost is null your activity will be null

I have a slightly different approach that might be useful/more beneficial to some.

Under your main project folder, create a resource folder. Your folder structure should look something like this.

• Project Folder
  • build
  • dist
  • lib
  • nbproject
  • resources
  • src

Go to the properties of your project. You can do this by right clicking on your project in the Projects tab window and selecting Properties in the drop down menu.

Under categories on the left side, select Sources.

In Source Package Folders on the right side, add your resource folder using the Add Folder button. Once you click OK, you should see a Resources folder under your project.

You should now be able to pull resources using this line or similar approach:

MyClass.class.getResource("/main.jpg");

If you were to create a package called Images under the resources folder, you can retrieve the resource like this:

MyClass.class.getResource("/Images/main.jpg");

Checkout their documentation

From the looks of it you could do the following on your docker-compose.yml

volumes:
    - ./:/app

Where ./ is the host directory, and /app is the target directory for the containers.

For the lazy – v3 / v2 / v1

You must first convert the string to a string array, like this:

$recipients = "Marcel <[email protected]>,Marcelt <[email protected]>"
[string[]]$To = $recipients.Split(',')

Then use Send-MailMessage like this:

Send-MailMessage -From "[email protected]" -To $To -subject "New files" -body "$teloadmin" -BodyAsHtml -priority High -dno onSuccess, onFailure -smtpServer 192.168.170.61

Consider a skewed binary tree with 3 nodes as 7, 3, 2. For any operation like for searching 2, we have to traverse 3 nodes, for deleting 2 also, we have to traverse 3 nodes and for for inserting 1 also, we have to traverse 3 nodes. So, binary tree has worst case complexity of O(n).

If you just want to run a function for testing purposes, you can use the Immediate Window in Access.

Press Ctrl + G in the VBA editor to open it.

Then you can run your functions like this:

• ?YourFunction("parameter")
  (for functions with a return value - the return value is displayed in the Immediate Window)
• YourSub "parameter"
  (for subs without a return value, or for functions when you don't care about the return value)
• ?variable
  (to display the value of a variable)
