Good question.

Here's a simple example based on GHZ's which might help someone:

>>> class person(object):
        def init(self,name):
            self.name=name
        def info(self)
            print "My name is {0}, I am a {1}".format(self.name,self.__class__.__name__)
>>> bob = person(name='Robert')
>>> bob.info()
My name is Robert, I am a person

Python classes are themselves objects - as in instance - of their meta-class.

The default metaclass, which is applied when when you determine classes as:

class foo:
    ...

meta class are used to apply some rule to an entire set of classes. For example, suppose you're building an ORM to access a database, and you want records from each table to be of a class mapped to that table (based on fields, business rules, etc..,), a possible use of metaclass is for instance, connection pool logic, which is share by all classes of record from all tables. Another use is logic to to support foreign keys, which involves multiple classes of records.

when you define metaclass, you subclass type, and can overrided the following magic methods to insert your logic.

class somemeta(type):
    __new__(mcs, name, bases, clsdict):
      """
  mcs: is the base metaclass, in this case type.
  name: name of the new class, as provided by the user.
  bases: tuple of base classes 
  clsdict: a dictionary containing all methods and attributes defined on class

  you must return a class object by invoking the __new__ constructor on the base metaclass. 
 ie: 
    return type.__call__(mcs, name, bases, clsdict).

  in the following case:

  class foo(baseclass):
        __metaclass__ = somemeta

  an_attr = 12

  def bar(self):
      ...

  @classmethod
  def foo(cls):
      ...

      arguments would be : ( somemeta, "foo", (baseclass, baseofbase,..., object), {"an_attr":12, "bar": <function>, "foo": <bound class method>}

      you can modify any of these values before passing on to type
      """
      return type.__call__(mcs, name, bases, clsdict)


    def __init__(self, name, bases, clsdict):
      """ 
      called after type has been created. unlike in standard classes, __init__ method cannot modify the instance (cls) - and should be used for class validaton.
      """
      pass


    def __prepare__():
        """
        returns a dict or something that can be used as a namespace.
        the type will then attach methods and attributes from class definition to it.

        call order :

        somemeta.__new__ ->  type.__new__ -> type.__init__ -> somemeta.__init__ 
        """
        return dict()

    def mymethod(cls):
        """ works like a classmethod, but for class objects. Also, my method will not be visible to instances of cls.
        """
        pass

anyhow, those two are the most commonly used hooks. metaclassing is powerful, and above is nowhere near and exhaustive list of uses for metaclassing.

You are really mixing together two different things.

Use dir(), vars() or the inspect module to get what you are interested in (I use __builtins__ as an example; you can use any object instead).

>>> l = dir(__builtins__)
>>> d = __builtins__.__dict__

Print that dictionary however fancy you like:

>>> print l
['ArithmeticError', 'AssertionError', 'AttributeError',...

or

>>> from pprint import pprint
>>> pprint(l)
['ArithmeticError',
 'AssertionError',
 'AttributeError',
 'BaseException',
 'DeprecationWarning',
...

>>> pprint(d, indent=2)
{ 'ArithmeticError': <type 'exceptions.ArithmeticError'>,
  'AssertionError': <type 'exceptions.AssertionError'>,
  'AttributeError': <type 'exceptions.AttributeError'>,
...
  '_': [ 'ArithmeticError',
         'AssertionError',
         'AttributeError',
         'BaseException',
         'DeprecationWarning',
...

Pretty printing is also available in the interactive debugger as a command:

(Pdb) pp vars()
{'__builtins__': {'ArithmeticError': <type 'exceptions.ArithmeticError'>,
                  'AssertionError': <type 'exceptions.AssertionError'>,
                  'AttributeError': <type 'exceptions.AttributeError'>,
                  'BaseException': <type 'exceptions.BaseException'>,
                  'BufferError': <type 'exceptions.BufferError'>,
                  ...
                  'zip': <built-in function zip>},
 '__file__': 'pass.py',
 '__name__': '__main__'}

In CPython, the number of arguments is

a_method.func_code.co_argcount

and their names are in the beginning of

a_method.func_code.co_varnames

These are implementation details of CPython, so this probably does not work in other implementations of Python, such as IronPython and Jython.

One portable way to admit "pass-through" arguments is to define your function with the signature func(*args, **kwargs). This is used a lot in e.g. matplotlib, where the outer API layer passes lots of keyword arguments to the lower-level API.

You can do something like this as demonstrated in perlfaq4:

sub uniq {
    my %seen;
    grep !$seen{$_}++, @_;
}

my @array = qw(one two three two three);
my @filtered = uniq(@array);

print "@filtered\n";

Outputs:

one two three

If you want to use a module, try the uniq function from List::MoreUtils

Keep in mind that the %CLASSPATH% environment variable is ignored when you use java/javac in combination with one of the -cp, -classpath or -jar arguments. It is also ignored in an IDE like Netbeans/Eclipse/IntelliJ/etc. It is only been used when you use java/javac without any of the above mentioned arguments.

In case of JAR files, the classpath is to be defined as class-path entry in the manifest.mf file. It can be defined semicolon separated and relative to the JAR file's root.

In case of an IDE, you have the so-called 'build path' which is basically the classpath which is used at both compiletime and runtime. To add external libraries you usually drop the JAR file in a (either precreated by IDE or custom created) lib folder of the project which is added to the project's build path.

You need to initialize it first:

p = Pump().getPumps()

Quickly and Simply I fixed it this way ( I use ADT version: v21.0.0-531062 on Windows XP home edition)

1. Opened manifest file.
2. Changed the Existing project minSdkVersion to the same value as maxSdkVersion ( advise: it may be good to create a New project and see what is it's maxSdkVersion )
3. Save manifest file.
4. Right Click the project and select Build Project.
5. From top menu: Project - Clean.. - check Only the relevant project, below I checked Start a build immediately and Build only the selected projects and OK.
6. open the java file - NO red errors anymore !
7. Back to step 1 above and changing Back minSdkVersion to it's Original value (to supoprt as many Android version as possible).

It worked BUT the problem returns every few days. I do the same as above and it solves and lets me develop.

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

Maybe your span is inheriting a style that forces its text to be normal instead of italic as you would like it. If you just can't get it to work as you want it to you might try marking your font-style as important.

.fancify {
    font-size: 1.5em;
    font-weight: 800;
    font-family: Consolas, "Segoe UI", Calibri, sans-serif;
    font-style: italic !important;
}

However try not to overuse important because it's easy to fall into CSS-hell with it.

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

The easiest way is to use a JsonResponse.

For a queryset, you should pass a list of the the values for that queryset, like so:

from django.http import JsonResponse

queryset = YourModel.objects.filter(some__filter="some value").values()
return JsonResponse({"models_to_return": list(queryset)})

If you have already installed 2.2.5 and set as current ruby version, but still showing the same error even if the Ruby version 2.3.0 is not even installed, then just install the bundler.

gem install bundler

and then:

bundle install

In your example, the TMP variable is set (and the temporary directory created) whenever the rules for out.tar are evaluated. In order to create the directory only when out.tar is actually fired, you need to move the directory creation down into the steps:

out.tar : 
    $(eval TMP := $(shell mktemp -d))
    @echo hi $(TMP)/hi.txt
    tar -C $(TMP) cf $@ .
    rm -rf $(TMP)

The eval function evaluates a string as if it had been typed into the makefile manually. In this case, it sets the TMP variable to the result of the shell function call.

edit (in response to comments):

To create a unique variable, you could do the following:

out.tar : 
    $(eval $@_TMP := $(shell mktemp -d))
    @echo hi $($@_TMP)/hi.txt
    tar -C $($@_TMP) cf $@ .
    rm -rf $($@_TMP)

This would prepend the name of the target (out.tar, in this case) to the variable, producing a variable with the name out.tar_TMP. Hopefully, that is enough to prevent conflicts.

Action is a Type of Delegate provided by the .NET framework. The Action points to a method with no parameters and does not return a value.

() => is lambda expression syntax. Lambda expressions are not of Type Delegate. Invoke requires Delegate so Action can be used to wrap the lambda expression and provide the expected Type to Invoke()

Invoke causes said Action to execute on the thread that created the Control's window handle. Changing threads is often necessary to avoid Exceptions. For example, if one tries to set the Rtf property on a RichTextBox when an Invoke is necessary, without first calling Invoke, then a Cross-thread operation not valid exception will be thrown. Check Control.InvokeRequired before calling Invoke.

BeginInvoke is the Asynchronous version of Invoke. Asynchronous means the thread will not block the caller as opposed to a synchronous call which is blocking.

There is no difference in working in both the concepts of assignment to unique_ptr.

int* intPtr = new int(3);
unique_ptr<int> uptr (intPtr);

is similar to

unique_ptr<int> uptr (new int(3));

Here unique_ptr automatically deletes the space occupied by uptr.

how pointers, declared in this way will be different from the pointers declared in a "normal" way.

If you create an integer in heap space (using new keyword or malloc), then you will have to clear that memory on your own (using delete or free respectively).

In the below code,

int* heapInt = new int(5);//initialize int in heap memory
.
.//use heapInt
.
delete heapInt;

Here, you will have to delete heapInt, when it is done using. If it is not deleted, then memory leakage occurs.

In order to avoid such memory leaks unique_ptr is used, where unique_ptr automatically deletes the space occupied by heapInt when it goes out of scope. So, you need not do delete or free for unique_ptr.

There's yet another way to do it using Shared Connections, ie: somebody initiates the connection, using a password, and every subsequent connection will multiplex over the same channel, negating the need for re-authentication. ( And its faster too )

# ~/.ssh/config 
ControlMaster auto
ControlPath ~/.ssh/pool/%r@%h

then you just have to log in, and as long as you are logged in, the bash script will be able to open ssh connections.

You can then stop your script from working when somebody has not already opened the channel by:

ssh ... -o KbdInteractiveAuthentication=no ....

It really all comes down to how you want to handle output that the command might return and whether you want your PHP script to wait for the callee program to finish or not.

• exec executes a command and passes output to the caller (or returns it in an optional variable).

• passthru is similar to the exec() function in that it executes a command . This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back to the browser.

• system executes an external program and displays the output, but only the last line.

If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

Structure types should, whenever practical, either have all of their state encapsulated in public fields which may independently be set to any values which are valid for their respective type, or else behave as a single unified value which can only bet set via constructor, factory, method, or else by passing an instance of the struct as an explicit ref parameter to one of its public methods. Contrary to what some people claim, that there's nothing wrong with a struct having public fields, if it is supposed to represent a set of values which may sensibly be either manipulated individually or passed around as a group (e.g. the coordinates of a point). Historically, there have been problems with structures that had public property setters, and a desire to avoid public fields (implying that setters should be used instead) has led some people to suggest that mutable structures should be avoided altogether, but fields do not have the problems that properties had. Indeed, an exposed-field struct is the ideal representation for a loose collection of independent variables, since it is just a loose collection of variables.

In your particular example, however, it appears that the two fields of your struct are probably not supposed to be independent. There are three ways your struct could sensibly be designed:

• You could have the only public field be the string, and then have a read-only "helper" property called length which would report its length if the string is non-null, or return zero if the string is null.

• You could have the struct not expose any public fields, property setters, or mutating methods, and have the contents of the only field--a private string--be specified in the object's constructor. As above, length would be a property that would report the length of the stored string.

• You could have the struct not expose any public fields, property setters, or mutating methods, and have two private fields: one for the string and one for the length, both of which would be set in a constructor that takes a string, stores it, measures its length, and stores that. Determining the length of a string is sufficiently fast that it probably wouldn't be worthwhile to compute and cache it, but it might be useful to have a structure that combined a string and its GetHashCode value.

It's important to be aware of a detail with regard to the third design, however: if non-threadsafe code causes one instance of the structure to be read while another thread is writing to it, that may cause the accidental creation of a struct instance whose field values are inconsistent. The resulting behaviors may be a little different from those that occur when classes are used in non-threadsafe fashion. Any code having anything to do with security must be careful not to assume that structure fields will be in a consistent state, since malicious code--even in a "full trust" enviroment--can easily generate structs whose state is inconsistent if that's what it wants to do.

PS -- If you wish to allow your structure to be initialized using an assignment from a string, I would suggest using an implicit conversion operator and making Length be a read-only property that returns the length of the underlying string if non-null, or zero if the string is null.

This is what worked for me (After trying every other solution i found ...):

Run adb reverse tcp:8081 tcp:8081 inside \Android\sdk\platform-tools

if no other solution worked, then just rename the inherits class of that problem causing aspx file and aspx.cs file to a new name, then rebuild the solution. then the issue will be solved for sure. this only worked for me.

eg :

in the aspx file do the following change the inherits class name to Defaultnew

<%@ Page Title="" Language="C#"  MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Defaultnew" %>

in the aspx.cs file rename the class to the same as used in aspx file

using System;
using System.Collections.Generic;
using System.Web;

public partial class Defaultnew : System.Web.UI.Page
{

A mix fix for the underscore map bug :P

_.mixin({ 
    mapobj : function( obj, iteratee, context ) {
        if (obj == null) return [];
        iteratee = _.iteratee(iteratee, context);
        var keys = obj.length !== +obj.length && _.keys(obj),
            length = (keys || obj).length,
            results = {},
            currentKey;
        for (var index = 0; index < length; index++) {
          currentKey = keys ? keys[index] : index;
          results[currentKey] = iteratee(obj[currentKey], currentKey, obj);
        }
        if ( _.isObject( obj ) ) {
            return _.object( results ) ;
        } 
        return results;
    }
}); 

A simple workaround that keeps the right key and return as object It is still used the same way as i guest you could used this function to override the bugy _.map function

or simply as me used it as a mixin

_.mapobj ( options , function( val, key, list ) 

Two examples of filtering out multiple lines with grep:

Put this in filename.txt:

abc
def
ghi
jkl

grep command using -E option with a pipe between tokens in a string:

grep -Ev 'def|jkl' filename.txt

prints:

abc
ghi

Command using -v option with pipe between tokens surrounded by parens:

egrep -v '(def|jkl)' filename.txt

prints:

abc
ghi

In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.

The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly property of a type found in the assembly.

The following example illustrates:

using System;
using System.Reflection;

public class Example
{
    public static void Main()
    {
        Console.WriteLine("The version of the currently executing assembly is: {0}",
                          typeof(Example).Assembly.GetName().Version);
    }
}

/* This example produces output similar to the following:
   The version of the currently executing assembly is: 1.1.0.0

Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.

Simple Java Program which connects to the SQL Server.

NOTE: You need to add sqljdbc.jar into the build path

// localhost : local computer acts as a server

// 1433 : SQL default port number

// username : sa

// password: use password, which is used at the time of installing SQL server management studio, In my case, it is 'root'

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

    public class Conn {
        public static void main(String[] args) throws InstantiationException, IllegalAccessException, ClassNotFoundException {

            Connection conn=null;
            try {
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
                conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=company", "sa", "root");

                if(conn!=null)
                    System.out.println("Database Successfully connected");

            } catch (SQLException e) {
                e.printStackTrace();
            }

        }
    }

I know what you're trying to do, but why not simply do this:

$('div').addClass('hover');

The class is already defined in your CSS...

As for you original question, this has been asked before and it is not possible unfortunately. e.g. http://forum.jquery.com/topic/jquery-triggering-css-pseudo-selectors-like-hover

However, your desired functionality may be possible if your Stylesheet is defined in Javascript. see: http://www.4pmp.com/2009/11/dynamic-css-pseudo-class-styles-with-jquery/

Hope this helps!

With Bootstrap 4, you can do it much more easily: http://v4-alpha.getbootstrap.com/layout/flexbox-grid/#vertical-alignment

All the above answers are correct. Just providing with your dataset to find perfect divisor:

#include <stdio.h>

int main() 
{

int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;

for (i=0 ; i < 7; i++) {
    if (j % arr[i] == 0)
        printf("%d is the perfect divisor of %d\n", arr[i], j);
}

return 0;
}

For time as YYYY-MM-dd

String time = new DateTime( yourData ).toString("yyyy-MM-dd");

And the Library of DateTime is:

import org.joda.time.DateTime;

We can do it by MySQL Workbench. Just execute this:

kill id;

Example:

kill 13412

That will remove it.

Check the Linux distribution, apt-get works in Debian based distro whereas yum works in Fedora based distro.

Ref: How to know distro name, execute command cat /etc/*-release

It is also possible your system administrator does not permit you (or did not put you in the group of users who have sudo permissions) to execute apt-get but if you have sudo access try to execute with sudo apt-get <package_name> if debian or yum install <package_name> if you are using Fedora.

Use OnClicklistener or you can use android:onClick="myMethod" in your button's xml code from which you going to open a new layout. So when that button is clicked your myMethod function will be called automatically. Your myMethod function in class look like this.

public void myMethod(View v) {
Intent intent=new Intent(context,SecondActivty.class);
startActivity(intent);
}

And in that SecondActivity.class set new layout in contentview.

<< is the left-shift operator, as it is in many other languages.

Here RAM_DEPTH will be 1 left-shifted by 8 bits, which is equivalent to 2^8, or 256.

Usinge the file argument in the print function, you can have different files per print:

print('Redirect output to file', file=open('/tmp/example.log', 'w'))

The primary key is used to work with different tables. This is the foundation of relational databases. If you have a book database it's better to create 2 tables - 1) books and 2) authors with INT primary key "id". Then you use id in books instead of authors name.

The unique key is used if you don't want to have repeated entries. For example you may have title in your book table and want to be sure there is only one entry for each title.

The function Correlate of numpy works with 2 1D arrays that you want to correlate and returns one correlation value.

The answers are not making it clear:

Use this.$refs.someName, but, in order to use it, you must add ref="someName" in the parent.

See demo below.

new Vue({_x000D_
  el: '#app',_x000D_
  mounted: function() {_x000D_
    var childSpanClassAttr = this.$refs.someName.getAttribute('class');_x000D_
    _x000D_
    console.log('<span> was declared with "class" attr -->', childSpanClassAttr);_x000D_
  }_x000D_
})

<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>_x000D_
_x000D_
<div id="app">_x000D_
  Parent._x000D_
  <span ref="someName" class="abc jkl xyz">Child Span</span>_x000D_
</div>

$refs and v-for

Notice that when used in conjunction with v-for, the this.$refs.someName will be an array:

new Vue({_x000D_
  el: '#app',_x000D_
  data: {_x000D_
    ages: [11, 22, 33]_x000D_
  },_x000D_
  mounted: function() {_x000D_
    console.log("<span> one's text....:", this.$refs.mySpan[0].innerText);_x000D_
    console.log("<span> two's text....:", this.$refs.mySpan[1].innerText);_x000D_
    console.log("<span> three's text..:", this.$refs.mySpan[2].innerText);_x000D_
  }_x000D_
})

span { display: inline-block; border: 1px solid red; }

<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>_x000D_
_x000D_
<div id="app">_x000D_
  Parent._x000D_
  <div v-for="age in ages">_x000D_
    <span ref="mySpan">Age is {{ age }}</span>_x000D_
  </div>_x000D_
</div>

No; an anonymous type can't be made to do anything except have a few properties. You will need to create your own type. I didn't read the linked article in depth, but it looks like it uses Reflection.Emit to create new types on the fly; but if you limit discussion to things within C# itself you can't do what you want.

In PowerShell, boolean parameters can be declared by mentioning their type before their variable.

    function GetWeb() {
             param([bool] $includeTags)
    ........
    ........
    }

You can assign value by passing $true | $false

    GetWeb -includeTags $true

There is a clean solution with C++ templates, without using sizeof(). The following getSize() function returns the size of any static array:

#include <cstddef>

template<typename T, size_t SIZE>
size_t getSize(T (&)[SIZE]) {
    return SIZE;
}

Here is an example with a foo_t structure:

#include <cstddef>

template<typename T, size_t SIZE>
size_t getSize(T (&)[SIZE]) {
    return SIZE;
}

struct foo_t {
    int ball;
};

int main()
{
    foo_t foos3[] = {{1},{2},{3}};
    foo_t foos5[] = {{1},{2},{3},{4},{5}};
    printf("%u\n", getSize(foos3));
    printf("%u\n", getSize(foos5));

    return 0;
}

Output:

3
5

list(map(chr, [66, 53, 0, 94]))

map(func, *iterables) --> map object Make an iterator that computes the function using arguments from each of the iterables. Stops when the shortest iterable is exhausted.

"Make an iterator"

means it will return an iterator.

"that computes the function using arguments from each of the iterables"

means that the next() function of the iterator will take one value of each iterables and pass each of them to one positional parameter of the function.

So you get an iterator from the map() funtion and jsut pass it to the list() builtin function or use list comprehensions.

if you already know your folder is: E:\ftproot\sales then you do not need to use Server.MapPath, this last one is needed if you only have a relative virtual path like ~/folder/folder1 and you want to know the real path in the disk...

I'd use a 'where not exists' -- exactly as you suggest in your title:

SELECT `voter`.`ID`, `voter`.`Last_Name`, `voter`.`First_Name`,
       `voter`.`Middle_Name`, `voter`.`Age`, `voter`.`Sex`,
       `voter`.`Party`, `voter`.`Demo`, `voter`.`PV`,
       `household`.`Address`, `household`.`City`, `household`.`Zip`
FROM (`voter`)
JOIN `household` ON `voter`.`House_ID`=`household`.`id`
WHERE `CT` = '5'
AND `Precnum` = 'CTY3'
AND  `Last_Name`  LIKE '%Cumbee%'
AND  `First_Name`  LIKE '%John%'

AND NOT EXISTS (
  SELECT * FROM `elimination`
   WHERE `elimination`.`voter_id` = `voter`.`ID`
)

ORDER BY `Last_Name` ASC
LIMIT 30

That may be marginally faster than doing a left join (of course, depending on your indexes, cardinality of your tables, etc), and is almost certainly much faster than using IN.

Type.GetProperties will list each of the properties of a given type. Then use PropertyInfo.GetValue to check the values.

You could read the html file manually and then use loadData or loadDataWithBaseUrl methods of WebView to show it.

The Google Finance Gadget API has been officially deprecated since October 2012, but as of April 2014, it's still active:

http://www.google.com/finance/info?q=NASDAQ:GOOG
http://www.google.com/finance/info?q=CURRENCY:GBPUSD
http://finance.google.com/finance/info?client=ig&q=AAPL,YHOO

You can also get charts: https://www.google.com/finance/getchart?q=YELP

Note that if your application is for public consumption, using the Google Finance API is against Google's terms of service.

I have several JDK (1.4, 1.5, 1.6) installed in C:\Java with their JREs. Then I let Sun update the public JRE in C:\Program Files\Java.
Lately there is an improvement, installing in jre6. Previously, there was a different folder per new version (1.5.0_4, 1.5.0_5, etc.), which was taking lot of space

Run command rndc querylog on or add querylog yes; to options{}; section in named.conf to activate that channel.

Also make sure you’re checking correct directory if your bind is chrooted.

I ran into the same problem and found that the documentation has example for this type of scenario (where we write STDERR TO STDOUT and always exit successfully with return code 0) without causing/catching an exception.

output = subprocess.check_output("ping -c 2 -W 2 1.1.1.1; exit 0", stderr=subprocess.STDOUT, shell=True)

Now, you can use standard string function find to check the output string output.

The FileInputStream class works directly with the underlying file system. If the file in question is not physically present there, it will fail to open it. The getResourceAsStream() method works differently. It tries to locate and load the resource using the ClassLoader of the class it is called on. This enables it to find, for example, resources embedded into jar files.

If using in ruby rails use the below code.

For calculating the path of the file, asset_path function is used to find the image that we are using inside of the rails code embedded in <%= code %>

<link rel="icon" type="image/png" href="<%= asset_path('icon_name.jpg')%>">

I think this is the efficient way to do, why so much headache

    <div class="full-row">
     <label for="email-id">Email Address<span style="color:red">*</span></label>
  <input type="email" id="email-id" name="email-id"  ng-model="user.email" >
    </div> 

Solution for me was to just do it server side

I used the C# WebClient library to get the data (in my case it was image data) and send it back to the client. There's probably something very similar in your chosen server-side language.

//Server side, api controller

[Route("api/ItemImage/GetItemImageFromURL")]
public IActionResult GetItemImageFromURL([FromQuery] string url)
{
    ItemImage image = new ItemImage();

    using(WebClient client = new WebClient()){

        image.Bytes = client.DownloadData(url);

        return Ok(image);
    }
}

You can tweak it to whatever your own use case is. The main point is client.DownloadData() worked without any CORS errors. Typically CORS issues are only between websites, hence it being okay to make 'cross-site' requests from your server.

Then the React fetch call is as simple as:

//React component

fetch(`api/ItemImage/GetItemImageFromURL?url=${imageURL}`, {            
        method: 'GET',
    })
    .then(resp => resp.json() as Promise<ItemImage>)
    .then(imgResponse => {

       // Do more stuff....
    )}

Yes.

$('a[href=\'http://google.com\']')

Found a npm package that makes this easy with RxJS as a service.

https://www.npmjs.com/package/ng2-simple-timer

You can 'subscribe' to an existing timer so you don't create a bazillion timers if you're using it many times in the same component.

For compatibility with all browsers stick with .ico.

.png is getting more and more support though as it is easier to create using multiple programs.

for .ico

<link rel="shortcut icon" href="http://example.com/myicon.ico" />

for .png, you need to specify the type

<link rel="icon" type="image/png" href="http://example.com/image.png" />

It's not possible.

And yes, I think MS made a mistake here.

Their decision does not make sense and forces programmers to write (as described above) a pointless wrapper class.

Here is a good example: Trying to extend static MS Unit testing class Assert: I want 1 more Assert method AreEqual(x1,x2).

The only way to do this is to point to different classes or write a wrapper around 100s of different Assert methods. Why!?

If the decision was being made to allow extensions of instances, I see no logical reason to not allow static extensions. The arguments about sectioning libraries does not stand up once instances can be extended.

You can use a higher-level function like:

file_put_contents($filename, $content);

which is identical to calling fopen(), fwrite(), and fclose() successively to write data to a file.

Docs: file_put_contents

If you have multiply rows to delete and you don't want to alter the structure of your tables you can use cursor. 1-You first need to select rows to delete(in a cursor) 2-Then for each row in the cursor you delete the referencing rows and after that delete the row him self.

Ex:

--id is primary key of MainTable
    declare @id int
    set @id = 1
    declare theMain cursor for select FK from MainTable where MainID = @id
    declare @fk_Id int
    open theMain
    fetch next from theMain into @fk_Id
    while @@fetch_status=0
    begin
        --fkid is the foreign key 
        --Must delete from Main Table first then child.
        delete from MainTable where fkid = @fk_Id
        delete from ReferencingTable where fkid = @fk_Id
        fetch next from theMain into @fk_Id
    end
    close theMain
    deallocate theMain

hope is useful

I solve this issue deleting the 10 packages in my android sdk manage.

Elegant Answer Today:

<<~TEXT
Hi #{user.name}, 

Thanks for raising the flag, we're always happy to help you.
Your issue will be resolved within 2 hours.
Please be patient!

Thanks again,
Team #{user.organization.name}
TEXT

Theres a difference in <<-TEXT and <<~TEXT, former retains the spacing inside block and latter doesn't.

There are other options as well. Like concatenation etc. but this one makes more sense in general.

If I am wrong here, let me know how...

If you're using jQuery, you can also use:

$.getJSON(url, function(data) { });

Then you can do things like

data.key1.something
data.key1.something_else

etc.

Add cellpadding and cellspacing to solve it. Edit: Also removed double pixel border.

Most of the time, the best solution is using distinct() from dplyr, as has already been suggested.

However, here's another approach that uses the slice() function from dplyr.

# Generate fake data for the example
  library(dplyr)
  set.seed(123)
  df <- data.frame(
    x = sample(0:1, 10, replace = T),
    y = sample(0:1, 10, replace = T),
    z = 1:10
  )

# In each group of rows formed by combinations of x and y
# retain only the first row

    df %>%
      group_by(x, y) %>%
      slice(1)

Difference from using the distinct() function

The advantage of this solution is that it makes it explicit which rows are retained from the original dataframe, and it can pair nicely with the arrange() function.

Let's say you had customer sales data and you wanted to retain one record per customer, and you want that record to be the one from their latest purchase. Then you could write:

customer_purchase_data %>%
   arrange(desc(Purchase_Date)) %>%
   group_by(Customer_ID) %>%
   slice(1)

For Mac/OSX the default location is /Users/<username>/Library/Android/sdk.

I was crazy looking how to generate a .keystore using in the shell a single line command, so I could run it from another application. This is the way:

echo y | keytool -genkeypair -dname "cn=Mark Jones, ou=JavaSoft, o=Sun, c=US" -alias business -keypass kpi135 -keystore /working/android.keystore -storepass ab987c -validity 20000

• dname is a unique identifier for the application in the .keystore

  • cn the full name of the person or organization that generates the .keystore
  • ou Organizational Unit that creates the project, its a subdivision of the Organization that creates it. Ex. android.google.com
  • o Organization owner of the whole project. Its a higher scope than ou. Ex.: google.com
  • c The country short code. Ex: For United States is "US"

• alias Identifier of the app as an single entity inside the .keystore (it can have many)

• keypass Password for protecting that specific alias.
• keystore Path where the .keystore file shall be created (the standard extension is actually .ks)
• storepass Password for protecting the whole .keystore content.
• validity Amout of days the app will be valid with this .keystore

It worked really well for me, it doesnt ask for anything else in the console, just creates the file. For more information see keytool - Key and Certificate Management Tool.

Several choices to do this...

Set background to green:

v.setBackgroundColor(0x00FF00);

Set background to green with Alpha:

v.setBackgroundColor(0xFF00FF00);

Set background to green with Color.GREEN constant:

v.setBackgroundColor(Color.GREEN);

Set background to green defining in Colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>     
    <color name="myGreen">#00FF00</color> 
    <color name="myGreenWithAlpha">#FF00FF00</color> 
</resources>

and using:

v.setBackgroundResource(R.color.myGreen);

and:

v.setBackgroundResource(R.color.myGreenWithAlpha);

or the longer winded:

v.setBackgroundColor(ContextCompat.getColor(getContext(), R.color.myGreen));

and:

v.setBackgroundColor(ContextCompat.getColor(getContext(), R.color.myGreenWithAlpha));

OK, if that's what you want, here's what I would do to fix your existing code:

from collections import Counter

def count_letters(words):
    counter = Counter()
    for word in words.split():
        counter.update(word)
    return sum(counter.itervalues())

words = "The grey old fox is an idiot"
print count_letters(words)  # 22

If you don't want to count certain non-whitespace characters, then you'll need to remove them -- inside the for loop if not sooner.

Android BluetoothAdapter docs say it has been available since API Level 5. API Level 5 is Android 2.0.

You can try using a backport of the Bluetooth API (have not tried it personally): http://code.google.com/p/backport-android-bluetooth/

dir.Delete(true); // true => recursive delete

If you are working with Web application you can try this.

StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />")

MariaDB running on Raspbian - the file containing bind-address is hard to pinpoint. MariaDB have some not-very-helpful-info on the subject.

I used

# sudo grep -R bind-address /etc 

to locate where the damn thing is.

I also had to set the privileges and hosts in the mysql like everyone above pointed out.

And also had some fun time opening the 3306 port for remote connections to my Raspberry Pi - finally used iptables-persistent.

All works great now.

You can call clear, and that will destroy all the objects, but that will not free the memory. Looping through the individual elements will not help either (what action would you even propose to take on the objects?) What you can do is this:

vector<tempObject>().swap(tempVector);

That will create an empty vector with no memory allocated and swap it with tempVector, effectively deallocating the memory.

C++11 also has the function shrink_to_fit, which you could call after the call to clear(), and it would theoretically shrink the capacity to fit the size (which is now 0). This is however, a non-binding request, and your implementation is free to ignore it.

This isn’t a solution in the sense that it doesn’t resolve the conditions which cause the message to appear in the logs, but the message can be suppressed by appending the following to conf/logging.properties:

org.apache.catalina.webresources.Cache.level = SEVERE

This filters out the “Unable to add the resource” logs, which are at level WARNING.

In my view a WARNING is not necessarily an error that needs to be addressed, but rather can be ignored if desired.

Your example fails because Thread methods take either one or zero arguments. To create a thread without passing arguments, your code looks like this:

void Start()
{
    // do stuff
}

void Test()
{
    new Thread(new ThreadStart(Start)).Start();
}

If you want to pass data to the thread, you need to encapsulate your data into a single object, whether that is a custom class of your own design, or a dictionary object or something else. You then need to use the ParameterizedThreadStart delegate, like so:

void Start(object data)
{
    MyClass myData = (MyClass)myData;
    // do stuff
}

void Test(MyClass data)
{
    new Thread(new ParameterizedThreadStart(Start)).Start(data);
}

Not the most elegant, but I do (for Python 3):

if hasattr(instance, '__iter__') and not isinstance(instance, (str, bytes)):
    ...

This allows other iterables (like Django querysets) but excludes strings and bytestrings. I typically use this in functions that accept either a single object ID or a list of object IDs. Sometimes the object IDs can be strings and I don't want to iterate over those character by character. :)

How about using %/sprintf:

i = 20
"%x" % i  #=> "14"

UPDATE mytbl
SET a = ABS(a)
where a < 0

The element has both an attribute and a property named checked. The property determines the current state.

The attribute is a string, and the property is a boolean. When the element is created from the HTML code, the attribute is set from the markup, and the property is set depending on the value of the attribute.

If there is no value for the attribute in the markup, the attribute becomes null, but the property is always either true or false, so it becomes false.

When you set the property, you should use a boolean value:

document.getElementById('myRadio').checked = true;

If you set the attribute, you use a string:

document.getElementById('myRadio').setAttribute('checked', 'checked');

Note that setting the attribute also changes the property, but setting the property doesn't change the attribute.

Note also that whatever value you set the attribute to, the property becomes true. Even if you use an empty string or null, setting the attribute means that it's checked. Use removeAttribute to uncheck the element using the attribute:

document.getElementById('myRadio').removeAttribute('checked');

I usually do as you describe:
Add a separate column with a random value (=RAND()) and then perform a sort on that column.

Might be more complex and prettyer ways (using macros etc), but this is fast enough and simple enough for me.

function search($array, $key, $value) 
{ 
    $results = array(); 

    if (is_array($array)) 
    { 
        if (isset($array[$key]) && $array[$key] == $value) 
            $results[] = $array; 

        foreach ($array as $subarray) 
            $results = array_merge($results, search($subarray, $key, $value)); 
    } 

    return $results; 
} 

The two syntaxes for stubbing are roughly equivalent. However, you can always use doReturn/when for stubbing; but there are cases where you can't use when/thenReturn. Stubbing void methods is one such. Others include use with Mockito spies, and stubbing the same method more than once.

One thing that when/thenReturn gives you, that doReturn/when doesn't, is type-checking of the value that you're returning, at compile time. However, I believe this is of almost no value - if you've got the type wrong, you'll find out as soon as you run your test.

I strongly recommend only using doReturn/when. There is no point in learning two syntaxes when one will do.

You may wish to refer to my answer at Forming Mockito "grammars" - a more detailed answer to a very closely related question.

Padding and packing are just two aspects of the same thing:

• packing or alignment is the size to which each member is rounded off
• padding is the extra space added to match the alignment

In mystruct_A, assuming a default alignment of 4, each member is aligned on a multiple of 4 bytes. Since the size of char is 1, the padding for a and c is 4 - 1 = 3 bytes while no padding is required for int b which is already 4 bytes. It works the same way for mystruct_B.

Had the same issue, probably some kind of bug.

Even the fullScroll(ScrollView.FOCUS_UP) from the other answer didn't work.
Only thing that worked for me was calling scroll_view.smoothScrollTo(0,0) right after the dialog is shown.

I faced this problem today, and the issue was I was preventing event default action in document onclick:

document.onclick = function(e) {
    e.preventDefault();
}

Document onclick usually is used for event delegation but it's wrong to prevent default for every event, you must do it only for required elements:

document.onclick = function(e) {
    if (e.target instanceof HTMLAnchorElement) e.preventDefault();
}

<form>.WindowState = FormWindowState.Minimized;

To get information about the table's column, you can use:

\dt+ [tablename]

To get information about the datatype in the table, you can use:

\dT+ [datatype]

string = "i'm from New York"
string.split(/\s+/).each{ |word,i| word.capitalize! unless i > 0 }.join(' ')
# => I'm from New York

If your purpose is the isolation, I think Docker is what you want.

Vagrant is a virtual machine manager. It allows you to script the virtual machine configuration as well as the provisioning. However, it is still a virtual machine depending on VirtualBox (or others) with a huge overhead. It requires you to have a hard drive file that can be huge, it takes a lot of ram, and performance may be not very good.

Docker on the other hand uses kernel cgroup and namespacing via LXC. It means that you are using the same kernel as the host and the same file system. You can use Dockerfile with the docker build command in order to handle the provisioning and configuration of your container. You have an example at docs.docker.com on how to make your Dockerfile; it is very intuitive.

The only reason you could want to use Vagrant is if you need to do BSD, Windows or other non-Linux development on your Ubuntu box. Otherwise, go for Docker.

You could try using MultiMap instead of HashMap

Initialising it will require fewer lines of codes. Adding and retrieving the values will also make it shorter.

Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();

would become:

Multimap<String, Integer> multiMap = ArrayListMultimap.create();

You can check this link: http://java.dzone.com/articles/hashmap-%E2%80%93-single-key-and

Version for a directory

get-item is your friendly helping hand here.

(get-item $scriptPath ).parent.parent

If you Want the string only

(get-item $scriptPath ).parent.parent.FullName

Version for a file

If $scriptPath points to a file then you have to call Directory property on it first, so the call would look like this

(get-item $scriptPath).Directory.Parent.Parent.FullName

Remarks
This will only work if $scriptPath exists. Otherwise you have to use Split-Path cmdlet.

I found a way to change the Application Output theme and everything that can't be edited from .css.

If you use osX:

1. Navigate to your Qt install directory.
2. Right click Qt Creator application and select "Show Package Contents"
3. Copy the following file to your desktop> Contents/Resources/themes/dark.creatortheme or /default.creatortheme. Depending on if you are using dark theme or default theme.
4. Edit the file in text editor.
5. Under [Palette], there is a line that says error=ffff0000.
6. Set a new color, save, and override the original file.

You can add

DBQuery.prototype._prettyShell = true

to your file in $HOME/.mongorc.js to enable pretty print globally by default.

You don't have to specify ':3306' after the IP, it's the default port for MySQL.

And if your MySQL server runs with another port than 3306, then you have to add '-P [port]' instead of adding it to the IP address.

The MySQL client won't recognize the syntax "host:port", you HAVE to use -P [port] instead.

And btw, if you use '-p password', it won't work and will ask you the password again. You have to stick the password to the -p : -ppassword. (still, it's a very bad habit, because anyone that could do a PS on your server could see the plain password...)

It depends on the size of your database.

SQL is based on the SET theory: there is no order inherently used when querying a table.

So if you were to run the first query, it would first order by product price and then product name, IF there were any duplicates in the price category, say $20 for example, it would then order those duplicates by their names, therefore always maintaining that when you run your query it will always return the same set of result in the same order.

If you were to run the second query, it would only order by the name, so if there were two products with the same name (for some odd reason) then they wouldn't have a guaranteed order after you run the query.

For me i install java version 8 and just select the java version in "JDK location":

Be aware that the path under src/main/resources must match the package path of your .class files wishing to access the resource. See my answer here.

Git told me how to do it.

if you typed:

git checkout <some-commit_number>

Save the status

git add .
git commit -m "some message"

Then:

 git push origin HEAD:<name-of-remote-branch>

I usually lose track of all of my -20001-type error codes, so I try to consolidate all my application errors into a nice package like such:

      v_msg := v_msg || ' - '||p_msg;
    END IF;

    RAISE_APPLICATION_ERROR(p_err, v_msg);
  END;
END;
/

Then call errors.raise_err(errors.invalid_foo_num, 'optional extra text') to use it, like such:

BEGIN
  BEGIN
    errors.raise_err(errors.invalid_foo_num, 'Insufficient Foo-age!');
  EXCEPTION
    WHEN errors.invalid_foo_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(errors.illegal_bar_num, 'Insufficient Bar-age!');
  EXCEPTION
    WHEN errors.illegal_bar_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(-10000, 'This Doesn''t Exist!!');
  EXCEPTION
    WHEN OTHERS THEN
      dbms_output.put_line(SQLERRM);
  END;
END;
/

produces this output:

ORA-20123: Invalid Foo! - Insufficient Foo-age!
ORA-20156: Illegal Bar! - Insufficient Bar-age!
ORA-20001: Unknown Error Specified! - USR-10000: This Doesn't Exist!!

Assuming that create and destroy are free functions (which seems to be the case from the OP's code snippet) with the following signatures:

Bar* create();
void destroy(Bar*);

You can write your class Foo like this

class Foo {

    std::unique_ptr<Bar, void(*)(Bar*)> ptr_;

    // ...

public:

    Foo() : ptr_(create(), destroy) { /* ... */ }

    // ...
};

Notice that you don't need to write any lambda or custom deleter here because destroy is already a deleter.

The warning message

[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

means that you somehow passed -P pom.xml to Maven which means "there is a profile called pom.xml; find it and activate it". Check your environment and your settings.xml for this flag and also look at all <profile> elements inside the various XML files.

Usually, mvn help:effective-pom is also useful to see what the real POM would look like.

Now the error means that you tried to configure Maven to build Java 8 code but you're not using a Java 8 runtime. Solutions:

1. Install Java 8
2. Make sure Maven uses Java 8 if you have it installed. JAVA_HOME is your friend
3. Configure the Java compiler in your pom.xml to a Java version which you actually have.

EBS is like the virtual disk of a VM:

• Durable, instances backed by EBS can be freely started and stopped (saving money)
• Can be snapshotted at any point in time, to get point-in-time backups
• AMIs can be created from EBS snapshots, so the EBS volume becomes a template for new systems

Instance storage is:

• Local, so generally faster
• Non-networked, in normal cases EBS I/O comes at the cost of network bandwidth (except for EBS-optimized instances, which have separate EBS bandwidth)
• Has limited I/O per second IOPS. Even provisioned I/O maxes out at a few thousand IOPS
• Fragile. As soon as the instance is stopped, you lose everything in instance storage.

Here's where to use each:

• Use EBS for the backing OS partition and permanent storage (DB data, critical logs, application config)
• Use instance storage for in-process data, noncritical logs, and transient application state. Example: external sort storage, tempfiles, etc.
• Instance storage can also be used for performance-critical data, when there's replication between instances (NoSQL DBs, distributed queue/message systems, and DBs with replication)
• Use S3 for data shared between systems: input dataset and processed results, or for static data used by each system when lauched.
• Use AMIs for prebaked, launchable servers

Well, if you like the developer way, Visual Studio Code allows you to specify the different file types for the tabSize. Here is the example of my settings.json with default four spaces and JavaScript/JSON two spaces:

{
  // I want my default to be 4, but JavaScript/JSON to be 2
  "editor.tabSize": 4,
  "[javascript]": {
    "editor.tabSize": 2
  },
  "[json]": {
    "editor.tabSize": 2
  },

  // This one forces the tab to be **space**
  "editor.insertSpaces": true
}

PS: Well, if you do not know how to open this file (specially in a new version of Visual Studio Code), you can:

1. Left-bottom gear →
2. Settings → top right Open Settings

Use Process Explorer to find the process id. Then use Handle to find out what files are open.

Eg handle -p

I like this approach because you are using utilities from Microsoft itself.

If you use the vim plugin https://github.com/tpope/vim-surround (or use VSCode Vim plugin, which comes with vim-surround pre-installed), its pretty convinient!

add

drop

ds' // drop surround `'`

change

cs'" // change surround from `'` to `"`

It even works for html tags!

cst<em> // change surround from current tag to `<em>`

I just need doctype html and should work fine in IE11, Edge and Chrome. I used below code it works fine.

function downloadPage(element, event) {
    var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);

    if ((navigator.userAgent.indexOf("MSIE") != -1) || (!!document.documentMode == true)) {
        document.execCommand('SaveAs', '1', 'page.html');
        event.preventDefault();
    } else {
        if(isChrome) {
            element.setAttribute('href','data:text/html;charset=UTF-8,'+encodeURIComponent('<!doctype html>' + document.documentElement.outerHTML));
        }
        element.setAttribute('download', 'page.html');
    }
}

and in your anchor tag use like this.

<a href="#" onclick="downloadPage(this,event);" download>Download entire page.</a>

Example

    function downloadPage(element, event) {_x000D_
     var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);_x000D_

There is a small difference between both.

Second declaration assignates the reference associated to the constant SOMEto the variable str

First declaration creates a new String having for value the value of the constant SOME and assignates its reference to the variable str.

In the first case, a second String has been created having the same value that SOME which implies more inititialization time. As a consequence, you should avoid it. Furthermore, at compile time, all constants SOMEare transformed into the same instance, which uses far less memory.

As a consequence, always prefer second syntax.

inside the Form, You can use this code. Replace your variable name (i use $variable)

<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">

Regarding your second requirement - you might be able to utilise the onerror event, ie. <img onerror="some javascript;"...

Update:

You could also try iterating through document.images in the dom. There is a complete boolean property which you might be able to use. I don't know for sure whether this will be suitable, but might be worth investigating.

Write it as a one-liner:

figure('position', [0, 0, 200, 500])  % create new figure with specified size  

floor a;
floor b;
a = -0.340515;

so what to do?

b = 65565 +a;
a = 65565 -b;

or

if(a < 0){
a = 65565-(65565+a);}

First thing, try a full rebuild. Clean and build (or just use rebuild). Every once in a long while that resolves bizarre build issues for me.

Next, comment out the rest of the code that is not in your example you have posted. Compile. Does that work?

If so, start adding segments back until one breaks it.

If not, make all the classes public and try again.

If that still fails, maybe try putting the trimmed down classes in the same file and rebuilding. At that point, there would be absolutely no reason for access issues. If that still fails, take up carpentry.

Add below lines in your .profile path

PATH=$PATH:$HOME/bin:$Dir_where_script_exists

export PATH

Now your script should work without ./

Try this:

$WorkingDir = Convert-Path .

Here is yet another (working) variant:

This opens a new gnome terminal, then in the new terminal it runs bash. The user's rc file is read first, then a command ls -la is sent for execution to the new shell before it turns interactive. The last echo adds an extra newline that is needed to finish execution.

gnome-terminal -- bash -c 'bash --rcfile <( cat ~/.bashrc; echo ls -la ; echo)'

I also find it useful sometimes to decorate the terminal, e.g. with colorfor better orientation.

gnome-terminal --profile green -- bash -c 'bash --rcfile <( cat ~/.bashrc; echo ls -la ; echo)'

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

A bit manual searching but its an alternative way...
Find the Oracle home or where the installation files for Oracle is installed on your linux server.

cd / <-- Goto root directory
find . -print| grep -i dbm*.sql

Result varies on how you installed Oracle but mine displays this

/db/oracle

Goto the folder

less /db/oracle/db1/sqlplus/doc/README.htm

scroll down and you should see something like this

SQL*Plus Release Notes - Release 11.2.0.2

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

If you are using BookId as an combined primary key, then remember to change your interface from:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, Long> {

to:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, BookId> {

And change the annotation @Embedded to @EmbeddedId, in your QueuedBook class like this:

public class QueuedBook implements Serializable {

@EmbeddedId
@NotNull
private BookId bookId;

When you use the -m option putty does not allocate a tty, it runs the command and quits. If you want to run an interactive script (such as a sql client), you need to tell it to allocate a tty with -t, see 3.8.3.12 -t and -T: control pseudo-terminal allocation. You'll avoid keeping a script on the server, as well as having to invoke it once you're connected.

Here's what I'm using to connect to mysql from a batch file:

#mysql.bat start putty -t -load "sessionname" -l username -pw password -m c:\mysql.sh

#mysql.sh mysql -h localhost -u username --password="foo" mydb

https://superuser.com/questions/587629/putty-run-a-remote-command-after-login-keep-the-shell-running

Another addition: be careful when replacing multiples and converting the type of the column back from object to float. If you want to be certain that your None's won't flip back to np.NaN's apply @andy-hayden's suggestion with using pd.where. Illustration of how replace can still go 'wrong':

In [1]: import pandas as pd

In [2]: import numpy as np

In [3]: df = pd.DataFrame({"a": [1, np.NAN, np.inf]})

In [4]: df
Out[4]:
     a
0  1.0
1  NaN
2  inf

In [5]: df.replace({np.NAN: None})
Out[5]:
      a
0     1
1  None
2   inf

In [6]: df.replace({np.NAN: None, np.inf: None})
Out[6]:
     a
0  1.0
1  NaN
2  NaN

In [7]: df.where((pd.notnull(df)), None).replace({np.inf: None})
Out[7]:
     a
0  1.0
1  NaN
2  NaN

pprint.pprint() is a good tool for this job:

>>> import pprint
>>> cars = {'A':{'speed':70,
...         'color':2},
...         'B':{'speed':60,
...         'color':3}}

{'A': {'color': 2,
       'speed': 70},
 'B': {'color': 3,
       'speed': 60}}

Why not just reload the page when the user rotates the screen with javascript

function doOnOrientationChange()
{
location.reload();
}

window.addEventListener('orientationchange', doOnOrientationChange);

If what is happening is that you have another server running on localhost and you want to give this new server a different local hostname like http://teamviewer/

I think that what you are actually looking for is Virtual Hosts functionality. I use Apache so I do not know how other web daemons support this. Maybe it is called Alias. Here is the Apache documentation:

Apache Virtual Hosts examples

Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
  id id2 somevalue
1  1   1         x
3  3   4         z

Inside the duplicated call, I'm simply passing only those columns from dat that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)

html:

<h4 data-toggle-selector="#me">toggle</h4>
<div id="me">content here</div>

    })
})

If you want to use the Create Aggregate function in SQL Server, this is how to do it. Doing it this way has the benefit of being able to write clean queries. Note this this process could be adapted to calculate a Percentile value fairly easily.

Create a new Visual Studio project and set the target framework to .NET 3.5 (this is for SQL 2008, it may be different in SQL 2012). Then create a class file and put in the following code, or c# equivalent:

Imports Microsoft.SqlServer.Server
Imports System.Data.SqlTypes
Imports System.IO

<Serializable>
<SqlUserDefinedAggregate(Format.UserDefined, IsInvariantToNulls:=True, IsInvariantToDuplicates:=False, _
  IsInvariantToOrder:=True, MaxByteSize:=-1, IsNullIfEmpty:=True)>
Public Class Median
  Implements IBinarySerialize
  Private _items As List(Of Decimal)

  Public Sub Init()
    _items = New List(Of Decimal)()
  End Sub

  Public Sub Accumulate(value As SqlDecimal)
    If Not value.IsNull Then
      _items.Add(value.Value)
    End If
  End Sub

  Public Sub Merge(other As Median)
    If other._items IsNot Nothing Then
      _items.AddRange(other._items)
    End If
  End Sub

  Public Function Terminate() As SqlDecimal
    If _items.Count <> 0 Then
      Dim result As Decimal
      _items = _items.OrderBy(Function(i) i).ToList()
      If _items.Count Mod 2 = 0 Then
        result = ((_items((_items.Count / 2) - 1)) + (_items(_items.Count / 2))) / 2@
      Else
        result = _items((_items.Count - 1) / 2)
      End If

      Return New SqlDecimal(result)
    Else
      Return New SqlDecimal()
    End If
  End Function

  Public Sub Read(r As BinaryReader) Implements IBinarySerialize.Read
    'deserialize it from a string
    Dim list = r.ReadString()
    _items = New List(Of Decimal)

    For Each value In list.Split(","c)
      Dim number As Decimal
      If Decimal.TryParse(value, number) Then
        _items.Add(number)
      End If
    Next

  End Sub

  Public Sub Write(w As BinaryWriter) Implements IBinarySerialize.Write
    'serialize the list to a string
    Dim list = ""

    For Each item In _items
      If list <> "" Then
        list += ","
      End If      
      list += item.ToString()
    Next
    w.Write(list)
  End Sub
End Class

Then compile it and copy the DLL and PDB file to your SQL Server machine and run the following command in SQL Server:

CREATE ASSEMBLY CustomAggregate FROM '{path to your DLL}'
WITH PERMISSION_SET=SAFE;
GO

CREATE AGGREGATE Median(@value decimal(9, 3))
RETURNS decimal(9, 3) 
EXTERNAL NAME [CustomAggregate].[{namespace of your DLL}.Median];
GO

You can then write a query to calculate the median like this: SELECT dbo.Median(Field) FROM Table

I was interested in this question, so I did a test just now. Using .NET Framework 4.5.2 on an Intel(R) Core(TM) i3-2328M CPU @ 2.20GHz, 2200 Mhz, 2 Core(s) with 8GB ram running Microsoft Windows 7 Ultimate.

It looks like LINQ might be faster than for each loop. Here are the results I got:

Exists = True
Time   = 174
Exists = True
Time   = 149

It would be interesting if some of you could copy & paste this code in a console app and test as well. Before testing with an object (Employee) I tried the same test with integers. LINQ was faster there as well.

Before creating a new branch always the best practice is to have the latest of repo in your local machine. Follow these steps for error free branch creation.

 1. $ git branch (check which branches exist and which one is currently active (prefixed with *). This helps you avoid creating duplicate/confusing branch name)
 2. $ git branch <new_branch> (creates new branch)
 3. $ git checkout new_branch
 4. $ git add . (After making changes in the current branch)
 5. $ git commit -m "type commit msg here"
 6. $ git checkout master (switch to master branch so that merging with new_branch can be done)
 7. $ git merge new_branch (starts merging)
 8. $ git push origin master (push to the remote server)

I referred this blog and I found it to be a cleaner approach.

gunzip <filename>

then

tar -xvf <tar-file-name>

This stored procedure inserts a rand number into a table. Look out, it inserts an endless numbers. Stop executing it when u get enough numbers.

create a table for the cursor:

CREATE TABLE [dbo].[SearchIndex](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Cursor] [nvarchar](255) NULL) 

GO

Create a table to contain your numbers:

CREATE TABLE [dbo].[ID](
[IDN] [int] IDENTITY(1,1) NOT NULL,
[ID] [int] NULL)

INSERTING THE SCRIPT :

INSERT INTO [SearchIndex]([Cursor])  SELECT N'INSERT INTO ID  SELECT   FLOOR(rand() * 9 + 1)  SELECT COUNT (ID) FROM ID

CREATING AND EXECUTING THE PROCEDURE:

CREATE PROCEDURE [dbo].[RandNumbers] AS
BEGIN
Declare  CURSE  CURSOR  FOR (SELECT  [Cursor] FROM [dbo].[SearchIndex]  WHERE [Cursor] IS NOT NULL)
DECLARE @RandNoSscript NVARCHAR (250)
OPEN CURSE
FETCH NEXT FROM CURSE
INTO @RandNoSscript 
WHILE @@FETCH_STATUS IS NOT NULL 
BEGIN
Print @RandNoSscript
EXEC SP_EXECUTESQL @RandNoSscript;  
 END
 END
GO

Fill your table:

EXEC RandNumbers

Using the link from Daniel, I made an extension to make it more usable:

//UITableViewController+Ext.m
- (void)hideEmptySeparators
{
    UIView *v = [[UIView alloc] initWithFrame:CGRectZero];
    v.backgroundColor = [UIColor clearColor];
    [self.tableView setTableFooterView:v];
    [v release];
}

After some testings, I found out that the size can be 0 and it works as well. So it doesn't add some kind of margin at the end of the table. So thanks wkw for this hack. I decided to post that here since I don't like redirect.

Another solution that I found to this issue is by wrapping the Text inside a View. Also set the style of the View to flex: 1.

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

I found hitting ctrl+break while the macro wasn't running fixed the problem.

Eclipse -> Preferences -> Java -> Build Path -> User Libraries -> New(Name it) -> Add external Jars

(I recommend dragging your new libraries into the eclipse folder before any of these steps to keep everything together, that way if you reinstall Eclipse or your OS you won't have to rwlink anything except the JDK) Now select the jar files you want. Click OK.

Right click on your project and choose Build Path -> Add Library

FYI just code and then right click and Source->Organize Imports

You can use GOTO statement. Try this. This is use full for you.

WHILE(@N <= @Count)
BEGIN
    GOTO FinalStateMent;
END

FinalStatement:
     Select @CoumnName from TableName

You can get the raw data by calling ReadAsStringAsAsync on the Request.Content property.

string result = await Request.Content.ReadAsStringAsync();

There are various overloads if you want it in a byte or in a stream. Since these are async-methods you need to make sure your controller is async:

public async Task<IHttpActionResult> GetSomething()
{
    var rawMessage = await Request.Content.ReadAsStringAsync();
    // ...
    return Ok();
}

EDIT: if you're receiving an empty string from this method, it means something else has already read it. When it does that, it leaves the pointer at the end. An alternative method of doing this is as follows:

public IHttpActionResult GetSomething()
{
    var reader = new StreamReader(Request.Body);
    reader.BaseStream.Seek(0, SeekOrigin.Begin); 
    var rawMessage = reader.ReadToEnd();

    return Ok();
}

In this case, your endpoint doesn't need to be async (unless you have other async-methods)

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

You Can easily Convert columns to VARBINARY(Max Length), The length must be the maximum you expect to avoid defective comparison, It's enough to set length as the column length. Trim column help you to compare the real value except space has a meaning and valued in your table columns, This is a simple sample and as you can see I Trim the columns value and then convert and compare.:

CONVERT(VARBINARY(250),LTRIM(RTRIM(Column1))) = CONVERT(VARBINARY(250),LTRIM(RTRIM(Column2)))

Hope this help.

In my case it was invisible spaces that postman didn't recognize, the above string of text renders as without spaces in postman. I disabled SSL certificate Validation and System Proxy even tried on postman chrome extension(which is about to be deprecated), but when I downloaded and tried Insomnia and it gave those red dots in the place where those spaces were, must have gotten there during copy/paste

As detailed in this answer, mayur & user3869623's answer's are now relating to a deprecated router. You can now pass multiple parameters as follows:

To call router:

this.router.navigate(['/myUrlPath', "someId", "another ID"]);

In routes.ts:

{ path: 'myUrlpath/:id1/:id2', component: componentToGoTo},

The problem has been well-identified. But there's a solution; make doSomething generic:

<T extends Animal> void doSomething<List<T> animals) {
}

now you can call doSomething with either List<Dog> or List<Cat> or List<Animal>.

Well, @Jon Skeet, if we're not worried about getting any more granular than days (and still rolling days into larger units rather than having a total day count), as per the OP, it's really not that difficult in C#. What makes date math so difficult is that the number of units in each composite unit often changes. Imagine if every 3rd gallon of gas was only 3 quarts, but each 12th was 7, except on Fridays, when...

Luckily, dates are just a long ride through the greatest integer function. These crazy exceptions are maddening, unless you've gone all the way through the wackily-comprised unit, when it's not a big deal any more. If you're born on 12/25/1900, you're still EXACTLY 100 on 12/25/2000, regardless of the leap years or seconds or daylight savings periods you've been through. As soon as you've slogged through the percentages that make up the last composite unit, you're back to unity. You've added one, and get to start over.

Which is just to say that if you're doing years to months to days, the only strangely comprised unit is the month (of days). If you need to borrow from the month value to handle a place where you're subtracting more days than you've got, you just need to know the number of days in the previous month. No other outliers matter.

And C# gives that to you in System.DateTime.DaysInMonth(intYear, intMonth).

(If your Now month is smaller than your Then month, there's no issue. Every year has 12 months.)

And the same deal if we go more granular... you just need to know how many (small units) are in the last (composite unit). Once you're past, you get another integer value more of (composite unit). Then subtract how many small units you missed starting where you did Then and add back how many of those you went past the composite unit break-off with your Now.

So here's what I've got from my first cut at subtracting two dates. It might work. Hopefully useful.

(EDIT: Changed NewMonth > OldMonth check to NewMonth >= OldMonth, as we don't need to borrow one if the Months are the same (ditto for days). That is, Nov 11 2011 minus Nov 9 2010 was giving -1 year, 12 months, 2 days (ie, 2 days, but the royal we borrowed when royalty didn't need to.)

(EDIT: Had to check for Month = Month when we needed to borrow days to subtract a dteThen.Day from dteNow.Day & dteNow.Day < dteThen.Day, as we had to subtract a year to get 11 months and the extra days. Okay, so there are a few outliers. ;^D I think I'm close now.)

        // and days get wacky.

        // Watch for the outlier of Month = Month with DayNow < DayThen, as then we've 
        // got to subtract one from the year diff to borrow a month and have enough

            // the LAST month into subtractable days
            // Stay with me -- because we borrowed days from the year, not the month,
            // this is much different than what appears to be a similar calculation below.
            // We know we're a full intDiffInYears years apart PLUS eleven months.
            // Now we need to know how many days occurred before dteThen was done with 
            // dteThen.Month.  Then we add the number of days we've "earned" in the current

            // 1 year 11 months - 12 months = 11 months difference
            // (days from 12/25 to the End Of Month) + (Begin of Month to 12/1) =

            // intDiffInMonth-th month to get to the current month/day in dteNow.
            // That is, if we're comparing 2/8/2011 to 11/7/2011, we've got (10/8-2/8) = 8
            // full months between the two dates.  But then we've got to go from 10/8 to
            // 11/07.  So that's the previous month's (October) number of days (31) minus
            // the number of days into the month dteThen went (8), giving the number of days

            // function on the month difference (23 to the end of the month + 7 into the
            // next month == 30 total days.  You gotta make it through October before you

    intDiffInYears = dteNow.Year - dteThen.Year - 1;

    // So if the dates were THEN: 6/15/1999 and NOW: 2/20/2010...
    // Diff in years is 2010-1999 = 11, but since we're not to 6/15 yet, it's only 10.
    // Diff in months is (Months in year == 12) - (Months lost between 1/1/1999 and 6/15/1999
    // when dteThen's clock wasn't yet rolling == 6) = 6 months, then you add the months we

You can do

var color =  System.Drawing.ColorTranslator.FromHtml("#FFFFFF");

Or this (you will need the System.Windows.Media namespace)

var color = (Color)ColorConverter.ConvertFromString("#FFFFFF");

If you do not mind having to compile/generate the file then you could use a pre processing technique. This gives you the power of the generate but results in a clean Verilog file which is often easier to debug and leads to less simulator issues.

I use RubyIt to generate verilog files from templates using ERB (Embedded Ruby).

parameter ROWBITS = <%= ROWBITS %> ;
always @(posedge sysclk) begin
  <% (0...ROWBITS).each do |addr| -%>
    temp[<%= addr %>] <= 1'b0;
  <% end -%>
end

Generating the module_name.v file with :

$ ruby_it --parameter ROWBITS=4 --outpath ./ --file ./module_name.rv

The generated module_name.v

parameter ROWBITS = 4 ;
always @(posedge sysclk) begin
  temp[0] <= 1'b0;
  temp[1] <= 1'b0;
  temp[2] <= 1'b0;
  temp[3] <= 1'b0;
end

Because you need parentheses around the value your looking for. So here : document.querySelector('a[data-a="1"]')

If you don't know in advance the value but is looking for it via variable you can use template literals :

Say we have divs with data-price

<div data-price="99">My okay price</div>
<div data-price="100">My too expensive price</div>

We want to find an element but with the number that someone chose (so we don't know it):

// User chose 99    
let chosenNumber = 99
document.querySelector(`[data-price="${chosenNumber}"`]

This also works:

db.Account.find().sort('UserName', -1)
db.Account.find().sort('UserName', 1)

I'm using this in my code, please comment if i'm doing something wrong here, thanks.

Something like this might be the easiest way.

    }

You have assing button to your imgButton variable:

    super.onCreate(savedInstanceState);

    imgButton.setOnClickListener(imgButtonHandler);

For CentOS 7.4 I first installed pip and then pycrypto using pip:

You could use this sample code:

Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
Ringtone ringtoneSound = RingtoneManager.getRingtone(getApplicationContext(), ringtoneUri)

if (ringtoneSound != null) {
    ringtoneSound.play();
}

Might be better to use a choice, don't have to type (or possibly mistype) your expressions more than once, and allows you to follow additional different behaviors.

I very often use count(/html/body) = 0, as the specific number of nodes is more interesting than the set. For example... when there is unexpectedly more than 1 node that matches your expression.

<xsl:choose>
    <xsl:when test="/html/body">
         <!-- Found the node(s) -->
    </xsl:when>
    <!-- more xsl:when here, if needed -->
    <xsl:otherwise>
         <!-- No node exists -->
    </xsl:otherwise>
</xsl:choose>

In my case to get my debug build - I have to turn off Instant Run option :

Then after run project - I found my build into Application\app\build\outputs\appDebug\apk directory

I recommend you try to suppress specific warnings by using @SuppressWarnings("squid:S2078").

For suppressing multiple warnings you can do it like this @SuppressWarnings({"squid:S2078", "squid:S2076"})

There is also the //NOSONAR comment that tells SonarQube to ignore all errors for a specific line.

Finally if you have the proper rights for the user interface you can issue a flag as a false positive directly from the interface.

The reason why I recommend suppression of specific warnings is that it's a better practice to block a specific issue instead of using //NOSONAR and risk a Sonar issue creeping in your code by accident.

You can read more about this in the FAQ

Edit: 6/30/16 SonarQube is now called SonarLint

In case you are wondering how to find the squid number. Just click on the Sonar message (ex. Remove this method to simply inherit it.) and the Sonar issue will expand.

On the bottom left it will have the squid number (ex. squid:S1185 Maintainability > Understandability)

So then you can suppress it by @SuppressWarnings("squid:S1185")

Other solutions mix regex syntaxes. To use perl/PCRE patterns for both search and replace, and only process matching files, this works quite well:

grep -rlIZPi 'match1' | xargs -0r perl -pi -e 's/match2/replace/gi;'

match1 and match2 are usually identical but match1 can be simplified to remove more advanced features that are only relevant to the substitution, e.g. capturing groups.

Translation: grep recursively and list matching filenames, each separated by nul to protect any special characters; pipe any filenames to xargs which is expecting a nul-separated list; if any filenames are received, pass them to perl to perform the actual substitutions.

For case-sensitive matching, drop the i flag from grep and the i pattern modifier from the s/// expression, but not the i flag from perl itself. Remove the I flag from grep to include binary files.

A simple tkinter code for Python 3 for setting background image .

from tkinter import *
from tkinter import messagebox
top = Tk()

C = Canvas(top, bg="blue", height=250, width=300)
filename = PhotoImage(file = "C:\\Users\\location\\imageName.png")
background_label = Label(top, image=filename)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

C.pack()
top.mainloop

Another alternative is numpy.broadcast_to(val,n) which returns in constant time regardless of the size and is also the most memory efficient (it returns a view of the repeated element). The caveat is that the returned value is read-only.

Below is a comparison of the performances of all the other methods that have been proposed using the same benchmark as in Nico Schlömer's answer.

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

To uninstall anaconda you have to:

1) Remove the entire anaconda install directory with:

rm -rf ~/anaconda2

2) And (OPTIONAL):

->Edit ~/.bash_profile to remove the anaconda directory from your PATH environment variable.

->Remove the following hidden file and folders that may have been created in the home directory:

rm -rf ~/.condarc ~/.conda ~/.continuum

This is surely an encoding problem. You have a different encoding in your database and in your website and this fact is the cause of the problem. Also if you ran that command you have to change the records that are already in your tables to convert those character in UTF-8.

Update: Based on your last comment, the core of the problem is that you have a database and a data source (the CSV file) which use different encoding. Hence you can convert your database in UTF-8 or, at least, when you get the data that are in the CSV, you have to convert them from UTF-8 to latin1.

How to distinguish lookahead and lookbehind? Take 2 minutes tour with me:

(?=) - positive lookahead
(?<=) - positive lookbehind

Suppose

    A  B  C #in a line

Now, we ask B, Where are you?
B has two solutions to declare it location:

One, B has A ahead and has C bebind
Two, B is ahead(lookahead) of C and behind (lookhehind) A.

As we can see, the behind and ahead are opposite in the two solutions.
Regex is solution Two.

publisher: where the events happen. Publisher should specify which delegate the class is using and generate necessary arguments, pass those arguments and itself to the delegate.

subscriber: where the response happen. Subscriber should specify methods to respond to events. These methods should take the same type of arguments as the delegate. Subscriber then add this method to publisher's delegate.

Therefore, when the event happen in publisher, delegate will receive some event arguments (data, etc), but publisher has no idea what will happen with all these data. Subscribers can create methods in their own class to respond to events in publisher's class, so that subscribers can respond to publisher's events.

Using binary AND with 0b1111:

String element = "el5";

char c = element.charAt(2);

System.out.println(c & 0b1111); // => '5' & 0b1111 => 0b0011_0101 & 0b0000_1111 => 5

// '0' & 0b1111 => 0b0011_0000 & 0b0000_1111 => 0
// '1' & 0b1111 => 0b0011_0001 & 0b0000_1111 => 1
// '2' & 0b1111 => 0b0011_0010 & 0b0000_1111 => 2
// '3' & 0b1111 => 0b0011_0011 & 0b0000_1111 => 3
// '4' & 0b1111 => 0b0011_0100 & 0b0000_1111 => 4
// '5' & 0b1111 => 0b0011_0101 & 0b0000_1111 => 5
// '6' & 0b1111 => 0b0011_0110 & 0b0000_1111 => 6
// '7' & 0b1111 => 0b0011_0111 & 0b0000_1111 => 7
// '8' & 0b1111 => 0b0011_1000 & 0b0000_1111 => 8
// '9' & 0b1111 => 0b0011_1001 & 0b0000_1111 => 9

Here goes a bunch of different ways to get the ID, including Scope_Identity:

If you only have one typeface you would like to add, and want less code to write, you can create a dedicated TextView for your specific font. See code below.

package com.yourpackage;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
    public static Typeface FONT_NAME;


    public FontTextView(Context context) {
        super(context);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
}

In main.xml, you can now add your textView like this:

<com.yourpackage.FontTextView
    android:id="@+id/tvTimer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="" />

Use a Profiler

Your approach will work nevertheless, but if you are looking for more sophisticated approaches. I'd suggest using a C# Profiler.

The advantages they have is:

• You can even get a statement level breakup
• No changes required in your codebase
• Instrumentions generally have very less overhead, hence very accurate results can be obtained.

There are many available open-source as well.

echo $pathInPieces = explode(DIRECTORY_SEPARATOR , __FILE__);
echo $pathInPieces[0].DIRECTORY_SEPARATOR;

You can simply show your actual image directory(less secure). By just 2 line of code.

 $dir = base_url()."photos/";

echo"<a href=".$dir.">Photo Directory</a>";

The command for listing all triggers is:

show triggers;

or you can access the INFORMATION_SCHEMA table directly by:

select trigger_schema, trigger_name, action_statement
from information_schema.triggers

• You can do this from version 5.0.10 onwards.
• More information about the TRIGGERS table is here.

Your constructor's access modifier would be package-private(default). As you have declared the class public, it will be visible everywhere, but the constructor will not. Your constructor will be visible only in its package.

package flight.booking;

public class FlightLog // Public access modifier
{
    private SpecificFlight flight;

    FlightLog(SpecificFlight flight) // Default access modifier
    {
        this.flight = flight;
    }
}

When you do not write any constructor in your class then the compiler generates a default constructor with the same access modifier of the class. For the following example, the compiler will generate a default constructor with the public access modifier (same as class).

package flight.booking;

public class FlightLog // Public access modifier
{
    private SpecificFlight flight;
}

You need to look for the Increase Font Size and Decrease Font Size options on the Keymap menu, you can see the options on my screenshot. You will find the Keymap menu under Preferences > Keymap.

Assigning on those will have the expected effect for font zoom.

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

In Swift 4.1 and Xcode 9.4.1

In iOS 11 this single line is enough:

detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]//Set your view here

See the complete code:

//In viewDidLoad
if #available(iOS 11.0, *) {
        detailsSubView.clipsToBounds = false
        detailsSubView.layer.cornerRadius = 10
        detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
} else {
      //For lower versions
}

But for lower versions

let rectShape = CAShapeLayer()
    rectShape.bounds = detailsSubView.frame
    rectShape.position = detailsSubView.center
    rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    detailsSubView.layer.mask = rectShape

Complete code is.

if #available(iOS 11.0, *) {
    detailsSubView.clipsToBounds = false
    detailsSubView.layer.cornerRadius = 10
    detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
} else {
    let rectShape = CAShapeLayer()
    rectShape.bounds = detailsSubView.frame
    rectShape.position = detailsSubView.center
    rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    detailsSubView.layer.mask = rectShape
}

If you are using AutoResizing in storyboard write this code in viewDidLayoutSubviews().

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if #available(iOS 11.0, *) {
        detailsSubView.clipsToBounds = false
        detailsSubView.layer.cornerRadius = 10
        detailsSubView.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner]
    } else {
        let rectShape = CAShapeLayer()
        rectShape.bounds = detailsSubView.frame
        rectShape.position = detailsSubView.center
        rectShape.path = UIBezierPath(roundedRect: detailsSubView.bounds,    byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: 20, height: 20)).cgPath
        detailsSubView.layer.mask = rectShape
    }
}

What is the return type of the round() method in the snippet?

If this is the Math.round() method, it returns a Long when the input param is Double.

So, you will have to cast the return value:

int a = (int) Math.round(doubleVar);

i've been with this issue using elementary OS loki. For like one day and i solved it restarting the adb using this command:

./adb kill-server

and

./adb start-server

You need to be in the Sdk folder >Platform Tools

Now, restart your phone this will restart all the process in your phone.

And that's how i fixed it.

React Router v4

There's a couple of things that I needed to get this working smoothly.

The doc page on auth workflow has quite a lot of what is required.

However I had three issues

1. Where does the props.history come from?
2. How do I pass it through to my component which isn't directly inside the Route component
3. What if I want other props?

I ended up using:

1. option 2 from an answer on 'Programmatically navigate using react router' - i.e. to use <Route render> which gets you props.history which can then be passed down to the children.
2. Use the render={routeProps => <MyComponent {...props} {routeProps} />} to combine other props from this answer on 'react-router - pass props to handler component'

N.B. With the render method you have to pass through the props from the Route component explicitly. You also want to use render and not component for performance reasons (component forces a reload every time).

const App = (props) => (
    <Route 
        path="/home" 
        render={routeProps => <MyComponent {...props} {...routeProps}>}
    />
)

const MyComponent = (props) => (
    /**
     * @link https://reacttraining.com/react-router/web/example/auth-workflow
     * N.B. I use `props.history` instead of `history`
     */
    <button onClick={() => {
        fakeAuth.signout(() => props.history.push('/foo'))
    }}>Sign out</button>
)

One of the confusing things I found is that in quite a few of the React Router v4 docs they use MyComponent = ({ match }) i.e. Object destructuring, which meant initially I didn't realise that Route passes down three props, match, location and history

I think some of the other answers here are assuming that everything is done via JavaScript classes.

Here's an example, plus if you don't need to pass any props through you can just use component

class App extends React.Component {
    render () {
        <Route 
            path="/home" 
            component={MyComponent}
        />
    }
}

class MyComponent extends React.Component {
    render () {
        /**
         * @link https://reacttraining.com/react-router/web/example/auth-workflow
         * N.B. I use `props.history` instead of `history`
         */
        <button onClick={() => {
            this.fakeAuth.signout(() => this.props.history.push('/foo'))
        }}>Sign out</button>
    }
}

I had problems due to atom being unable to write its logfile when starting from the commandline. This cured it.

sudo chmod 777 ~/.atom/nohup.out

Update for 2020/07

Finally, Anaconda3-2020.07 is out and its core is Python 3.8!

You can now download Anaconda packed with Python 3.8 goodness at:

As has been mentioned by others, std::unique_lock tracks the locked status of the mutex, so you can defer locking until after construction of the lock, and unlock before destruction of the lock. std::lock_guard does not permit this.

There seems no reason why the std::condition_variable wait functions should not take a lock_guard as well as a unique_lock, because whenever a wait ends (for whatever reason) the mutex is automatically reacquired so that would not cause any semantic violation. However according to the standard, to use a std::lock_guard with a condition variable you have to use a std::condition_variable_any instead of std::condition_variable.

Edit: deleted "Using the pthreads interface std::condition_variable and std::condition_variable_any should be identical". On looking at gcc's implementation:

• std::condition_variable::wait(std::unique_lock&) just calls pthread_cond_wait() on the underlying pthread condition variable with respect to the mutex held by unique_lock (and so could equally do the same for lock_guard, but doesn't because the standard doesn't provide for that)
• std::condition_variable_any can work with any lockable object, including one which is not a mutex lock at all (it could therefore even work with an inter-process semaphore)

I had exactly this problem with the exception that the Person class had a embedded key class. My own solution was to join them in the query AND remove

@Fetch(FetchMode.JOIN)

My embedded id class:

@Embeddable
public class MessageRecipientId implements Serializable {

    @ManyToOne(targetEntity = Message.class, fetch = FetchType.LAZY)
    @JoinColumn(name="messageId")
    private Message message;
    private String governmentId;

    public MessageRecipientId() {
    }

    public Message getMessage() {
        return message;
    }

    public void setMessage(Message message) {
        this.message = message;
    }

    public String getGovernmentId() {
        return governmentId;
    }

    public void setGovernmentId(String governmentId) {
        this.governmentId = governmentId;
    }

    public MessageRecipientId(Message message, GovernmentId governmentId) {
        this.message = message;
        this.governmentId = governmentId.getValue();
    }

}

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

A working code:

private void changeScreenOrientation() {
    int orientation = yourActivityName.this.getResources().getConfiguration().orientation;
    if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        showMediaDescription();
    } else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        hideMediaDescription();
    }
    if (Settings.System.getInt(getContentResolver(),
            Settings.System.ACCELEROMETER_ROTATION, 0) == 1) {
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
            }
        }, 4000);
    }
}

call this method in your button click

In your function check for the keycode 8 (backspace) or 46 (delete)

Keycode information
Keycode list

The man pages is the best source of information you can find... and is at your fingertips: man mkdir yields this about -p switch:

-p, --parents
    no error if existing, make parent directories as needed

Use case example: Assume I want to create directories hello/goodbye but none exist:

$mkdir hello/goodbye
mkdir:cannot create directory 'hello/goodbye': No such file or directory
$mkdir -p hello/goodbye
$

-p created both, hello and goodbye

This means that the command will create all the directories necessaries to fulfill your request, not returning any error in case that directory exists.

About rlidwka, Google has a very good memory for acronyms :). My search returned this for example: http://www.cs.cmu.edu/~help/afs/afs_acls.html

 Directory permissions

l (lookup)
    Allows one to list the contents of a directory. It does not allow the reading of files. 
i (insert)
    Allows one to create new files in a directory or copy new files to a directory. 
d (delete)
    Allows one to remove files and sub-directories from a directory. 
a (administer)
    Allows one to change a directory's ACL. The owner of a directory can always change the ACL of a directory that s/he owns, along with the ACLs of any subdirectories in that directory. 

File permissions

r (read)
    Allows one to read the contents of file in the directory. 
w (write)
    Allows one to modify the contents of files in a directory and use chmod on them. 
k (lock)
    Allows programs to lock files in a directory. 

Hence rlidwka means: All permissions on.

It's worth mentioning, as @KeithThompson pointed out in the comments, that not all Unix systems support ACL. So probably the rlidwka concept doesn't apply here.
