This post will go through the following topics:

• Merging with index under different conditions
  • options for index-based joins: merge, join, concat
  • merging on indexes
  • merging on index of one, column of other
• effectively using named indexes to simplify merging syntax

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

The other answers did not solve the problem for my case. This works for me:

• Try deleting your build output.
• For me, that means deleting general.dll.js

Additional Details

• Windows 10 64bit dev machine
• NPM Start running webpack generating a build file: general.dll.js
• If I get the ELIFECYCLE error upon "NPM Start" it is often after I have already successfully executed "NPM Start" but then stopped it, only to start "NPM Start" again.
• I noticed that general.dll.js showed up in some of the hard-to-understand logs

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

By the way,it's a good way to use try catch if you want to convert string to int:

try:
  i = int(s)
except ValueError as err:
  pass 

Hope this helps.

A much simpler solution to this problem that allows letters, numbers and words as the label is the following code. More specifically, the line of code starting with "icon:". Any string or variable could be substituted for 'k'.

for (i = 0; i < locations.length; i++) 
      { 
      k = i + 1;
      marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),     
      map: map,
      icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=' + k + '|FF0000|000000'
});

--- the locations array holds the lat and long and k is the row number for the address I was mapping. In other words if I had a 100 addresses to map my marker labels would be 1 to 100.

You probably don't want to do this:

#include "client.cpp"

A *.cpp file will have been compiled by the compiler as part of your build. By including it in other files, it will be compiled again (and again!) in every file in which you include it.

Now here's the thing: You are guarding it with #ifndef SOCKET_CLIENT_CLASS, however, each file that has #include "client.cpp" is built independently and as such will find SOCKET_CLIENT_CLASS not yet defined. Therefore it's contents will be included, not #ifdef'd out.

If it contains any definitions at all (rather than just declarations) then these definitions will be repeated in every file where it's included.

You cannot color plain text in a GitHub README.md file. You can however add color to code samples with the tags below.

To do this just add tags such as these samples to your README.md file:

```json
   // code for coloring
```
```html
   // code for coloring
```
```js
   // code for coloring
```
```css
   // code for coloring
```
// etc.

No "pre" or "code" tags needed.

This is covered in the GitHub Markdown documentation (about half way down the page, there's an example using Ruby). GitHub uses Linguist to identify and highlight syntax - you can find a full list of supported languages (as well as their markdown keywords) over in the Linguist's YAML file.

I do have same problem when i was trying out with first Spring MVC webapp . What i had done was downloaded the jar files given from the link(Download spring framework). Among the jars on the zip extracted folder,the jar files I was expected to use were

• org.springframework.asm-3.0.1.RELEASE-A.jar

• org.springframework.beans-3.0.1.RELEASE-A.jar

• org.springframework.context-3.0.1.RELEASE-A.jar

• org.springframework.core-3.0.1.RELEASE-A.jar

• org.springframework.expression-3.0.1.RELEASE-A.jar

• org.springframework.web.servlet-3.0.1.RELEASE-A.jar

• org.springframework.web-3.0.1.RELEASE-A.jar

But as I get the Error, looking out for solution, I figured out that I also need the following jar too.

• commons-logging-1.0.4.jar

• jstl-1.2.jar

Then I searched and downloaded the two jar files separately and include them in /WEB-INF/lib folder. And finally I was able to get my webapp running using the Tomcat server. :)

Currently, it is not possible to prevent a user from writing decimal values in your input with HTML only. You have to use javascript.

Happen to have a task on pivot. Below works for me as tested just now on 11g:

select * from
(
  select ID, COUNTRY_NAME, TOTAL_COUNT from ONE_TABLE 
) 
pivot(
  SUM(TOTAL_COUNT) for COUNTRY_NAME in (
    'Canada', 'USA', 'Mexico'
  )
);

This answer helped me https://stackoverflow.com/a/18880670/1821607 The reason of crush — index 0 wasn't set. Simple $array = $array + array(null) did the trick. Or you should check whether array element on index 0 is set via isset($array[0]). The second variant is the best approach for me.

create table like this,

CommentId    UserId
---------------------
   1            usr1
   1            usr2

In this way you can check whether the user posted the comments are not.. Apart from this there should be tables for Comments and Users with respective id's

• Does jQuery heavily rely on browser sniffing? Could be that potential problem in future? Why?

No - there is the $.browser method, but it's deprecated and isn't used in the core.

• I found plenty JS-selector engines, are there any AJAX and FX libraries?

Loads. jQuery is often chosen because it does AJAX and animations well, and is easily extensible. jQuery doesn't use it's own selector engine, it uses Sizzle, an incredibly fast selector engine.

• Is there any reason (besides browser sniffing and personal "hate" against John Resig) why jQuery is wrong?

No - it's quick, relatively small and easy to extend.

For me personally it's nice to know that as browsers include more stuff (classlist API for example) that jQuery will update to include it, meaning that my code runs as fast as possible all the time.

Read through the source if you are interested, http://code.jquery.com/jquery-1.4.3.js - you'll see that features are added based on the best case first, and gradually backported to legacy browsers - for example, a section of the parseJSON method from 1.4.3:

return window.JSON && window.JSON.parse ?
    window.JSON.parse( data ) :
    (new Function("return " + data))();

As you can see, if window.JSON exists, the browser uses the native JSON parser, if not, then it avoids using eval (because otherwise minfiers won't minify this bit) and sets up a function that returns the data. This idea of assuming modern techniques first, then degrading to older methods is used throughout meaning that new browsers get to use all the whizz bang features without sacrificing legacy compatibility.

CREATE TABLE `voting` (
  `QuestionID` int(10) unsigned NOT NULL,
  `MemberId` int(10) unsigned NOT NULL,
  `vote` int(10) unsigned NOT NULL,
  PRIMARY KEY  (`QuestionID`,`MemberId`)
);

With pivot_data as
(
select 
action, -- grouping column
view_edit -- spreading column
from tbl
)
select action, [view], [edit]
from   pivot_data
pivot  ( max(view_edit) for view_edit in ([view], [edit]) ) as p;

For PostgreSQL example:

UPDATE TableA AS a
SET param_from_table_a=FALSE -- param FROM TableA
FROM TableB AS b
WHERE b.id=a.param_id AND a.amount <> 0; 

If the function is from a source file available on the filesystem, then inspect.getsource(foo) might be of help:

If foo is defined as:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a  

Then:

import inspect
lines = inspect.getsource(foo)
print(lines)

Returns:

def foo(arg1,arg2):         
    #do something with args 
    a = arg1 + arg2         
    return a                

But I believe that if the function is compiled from a string, stream or imported from a compiled file, then you cannot retrieve its source code.

What to do:

1. configure exploded war artifact to have extension .war
2. deploy exploded artifact to WildFly or Jboss

Absolutely Asset Catalog is you answer, it removes the need to follow naming conventions when you are adding or updating your app icons.

Below are the steps to Migrating an App Icon Set or Launch Image Set From Apple:

1- In the project navigator, select your target.

2- Select the General pane, and scroll to the App Icons section.

3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears.

4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button, selecting an asset catalog from the popup menu, and clicking the Migrate button.

Alternatively, you can create an empty app icon set by choosing Editor > New App Icon, and add images to the set by dragging them from the Finder or by choosing Editor > Import.

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)

according jdk source code from javasourcecode.org, HashSet use HashMap as its inside implementation, the code about put method of HashSet is below :

public V put(K key, V value) {
        if (key == null)
            return putForNullKey(value);
        int hash = hash(key.hashCode());
        int i = indexFor(hash, table.length);
        for (Entry<K,V> e = table[i]; e != null; e = e.next) {
            Object k;
            if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
                V oldValue = e.value;
                e.value = value;
                e.recordAccess(this);
                return oldValue;
            }
        }

        modCount++;
        addEntry(hash, key, value, i);
        return null;
    }

The rule is firstly check the hash, then check the reference and then call equals method of the object will be putted in.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

Using forward declarations instead of a full #includes is possible only when you are not intending on using the type itself (in this file's scope) but a pointer or reference to it.

To use the type itself, the compiler must know its size - hence its full declaration must be seen - hence a full #include is needed.

However, the size of a pointer or reference is known to the compiler, regardless of the size of the pointee, so a forward declaration is sufficient - it declares a type identifier name.

Interestingly, when using pointer or reference to class or struct types, the compiler can handle incomplete types saving you the need to forward declare the pointee types as well:

// header.h

// Look Ma! No forward declarations!
typedef class A* APtr; // class A is an incomplete type - no fwd. decl. anywhere
typedef class A& ARef;

typedef struct B* BPtr; // struct B is an incomplete type - no fwd. decl. anywhere
typedef struct B& BRef;

// Using the name without the class/struct specifier requires fwd. decl. the type itself.    
class C;         // fwd. decl. type
typedef C* CPtr; // no class/struct specifier 
typedef C& CRef; // no class/struct specifier 

struct D;        // fwd. decl. type
typedef D* DPtr; // no class/struct specifier 
typedef D& DRef; // no class/struct specifier 

Please note that when plotting a line chart, using =NA() (output #N/A) to avoid plotting non existing values will only work for the ends of each series, first and last values. Any #N/A in between two other values will be ignored and bridged.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

I've experienced same problem with same lib, found a solution here on SO:

Search MSDN for "How to: Set Environment Variables for Projects". (It's Project>Properties>Configuration Properties>Debugging "Environment" and "Merge Environment" properties for those who are in a rush.)

The syntax is NAME=VALUE and macros can be used (for example, $(OutDir)).

For example, to prepend C:\Windows\Temp to the PATH:

PATH=C:\WINDOWS\Temp;%PATH%

Similarly, to append $(TargetDir)\DLLS to the PATH:

PATH=%PATH%;$(TargetDir)\DLLS

(answered by Multicollinearity here: How do I set a path in visual studio?

A variable prefixed with @ is an instance variable, while one prefixed with @@ is a class variable. Check out the following example; its output is in the comments at the end of the puts lines:

class Test
  @@shared = 1

  def value
    @@shared
  end

  def value=(value)
    @@shared = value
  end
end

class AnotherTest < Test; end

t = Test.new
puts "t.value is #{t.value}" # 1
t.value = 2
puts "t.value is #{t.value}" # 2

x = Test.new
puts "x.value is #{x.value}" # 2

a = AnotherTest.new
puts "a.value is #{a.value}" # 2
a.value = 3
puts "a.value is #{a.value}" # 3
puts "t.value is #{t.value}" # 3
puts "x.value is #{x.value}" # 3

You can see that @@shared is shared between the classes; setting the value in an instance of one changes the value for all other instances of that class and even child classes, where a variable named @shared, with one @, would not be.

[Update]

As Phrogz mentions in the comments, it's a common idiom in Ruby to track class-level data with an instance variable on the class itself. This can be a tricky subject to wrap your mind around, and there is plenty of additional reading on the subject, but think about it as modifying the Class class, but only the instance of the Class class you're working with. An example:

class Polygon
  class << self
    attr_accessor :sides
  end
end

class Triangle < Polygon
  @sides = 3
end

class Rectangle < Polygon
  @sides = 4
end

class Square < Rectangle
end

class Hexagon < Polygon
  @sides = 6
end

puts "Triangle.sides:  #{Triangle.sides.inspect}"  # 3
puts "Rectangle.sides: #{Rectangle.sides.inspect}" # 4
puts "Square.sides:    #{Square.sides.inspect}"    # nil
puts "Hexagon.sides:   #{Hexagon.sides.inspect}"   # 6

I included the Square example (which outputs nil) to demonstrate that this may not behave 100% as you expect; the article I linked above has plenty of additional information on the subject.

Also keep in mind that, as with most data, you should be extremely careful with class variables in a multithreaded environment, as per dmarkow's comment.

WAITFOR DELAY 'HH:MM:SS'

I believe the maximum time this can wait for is 23 hours, 59 minutes and 59 seconds.

Here's a Scalar-valued function to show it's use; the below function will take an integer parameter of seconds, which it then translates into HH:MM:SS and executes it using the EXEC sp_executesql @sqlcode command to query. Below function is for demonstration only, i know it's not fit for purpose really as a scalar-valued function! :-)

    -- 'maximum wait time is 23 hours, 59 minutes and 59 seconds.'
    END


    declare @sql nvarchar(24) = 'WAITFOR DELAY '+char(39)+cast(@hours as nvarchar(2))+':'+CAST(@mins as nvarchar(2))+':'+CAST(@secs as nvarchar(2))+char(39)


    exec sp_executesql @sql

    return ''
    END

IF you wish to delay longer than 24 hours, I suggest you use a @Days parameter to go for a number of days and wrap the function executable inside a loop... e.g..

    Declare @Days int = 5
    Declare @CurrentDay int = 1

    WHILE @CurrentDay <= @Days
    BEGIN

    --24 hours, function will run for 23 hours, 59 minutes, 59 seconds per run.
    [ufn_DelayFor_MaxTimeIs24Hours] 86400

    SELECT @CurrentDay = @CurrentDay + 1
    END

Use a timer. Keep in mind that .NET comes with a number of different timers. This article covers the differences.

You are writing to memory you do not own:

int board[2][50]; //make an array with 3 columns  (wrong)
                  //(actually makes an array with only two 'columns')
...
for (i=0; i<num3+1; i++)
    board[2][i] = 'O';
          ^

Change this line:

int board[2][50]; //array with 2 columns (legal indices [0-1][0-49])
          ^

To:

int board[3][50]; //array with 3 columns (legal indices [0-2][0-49])
          ^

When creating an array, the value used to initialize: [3] indicates array size.
However, when accessing existing array elements, index values are zero based.

For an array created: int board[3][50];
Legal indices are board[0][0]...board[2][49]

EDIT To address bad output comment and initialization comment

add an additional "\n" for formatting output:

Change:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
 }

       ...

To:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
  printf("\n");//at the end of every row, print a new line
}
...  

Initialize board variable:

int board[3][50] = {0};//initialize all elements to zero

( array initialization discussion... )

Try PowerShell 2.0's EventLog cmdlets

Throwing this in for PowerShell 2.0 and upwards:

• Run New-EventLog once to register the event source:

  New-EventLog -LogName Application -Source MyApp
  

• Then use Write-EventLog to write to the log:

  Write-EventLog 
      -LogName Application 
      -Source MyApp 
      -EntryType Error 
      -Message "Immunity to iocaine powder not detected, dying now" 
      -EventId 1
  

If you are using phpmyadmin to add new routine then don't forget to wrap your code between BEGIN and END

If you are storing metadata in a tag use data attributes eg.

<li id="song1" data-value="song1.ogg"><button onclick="updateSource()">Item1</button></li>

Now use the attribute to get the name of the song

var audio = document.getElementById('audio');
audio.src='audio/ogg/' + document.getElementById('song1').getAttribute('data-value');
audio.load();

The RootTools library offers simple methods to check for root:

RootTools.isRootAvailable()

Reference

The simplest solution may be to add HINTS to each find_* request.

For example:

find_library(CURL_LIBRARY
    NAMES curl curllib libcurl_imp curllib_static
    HINTS "${CMAKE_PREFIX_PATH}/curl/lib"
)

For Boost I would strongly recommend using the FindBoost standard module and setting the BOOST_DIR variable to point to your Boost libraries.

$ python -c "import itertools; a=[2,3,5,7,11]; print sum([list(itertools.combinations(a, i)) for i in range(len(a)+1)], [])" [(), (2,), (3,), (5,), (7,), (11,), (2, 3), (2, 5), (2, 7), (2, 11), (3, 5), (3, 7), (3, 11), (5, 7), (5, 11), (7, 11), (2, 3, 5), (2, 3, 7), (2, 3, 11), (2, 5, 7), (2, 5, 11), (2, 7, 11), (3, 5, 7), (3, 5, 11), (3, 7, 11), (5, 7, 11), (2, 3, 5, 7), (2, 3, 5, 11), (2, 3, 7, 11), (2, 5, 7, 11), (3, 5, 7, 11), (2, 3, 5, 7, 11)]

echo "12|23|11" | awk '{split($0,a,"|"); print a[3] a[2] a[1]}'

should work.

when you use \\b(\\w+)+\\b that means exact match with a word containing only word characters ([a-zA-Z0-9])

in your case for example setting \\b at the begining of regex will accept -12(with space) but again it won't accept -12(without space)

for reference to support my words: https://docs.oracle.com/javase/tutorial/essential/regex/bounds.html

First of all understand this, before .NET framework, Microsoft were providing the stand-alone products like MFC (Visual C++), VB, FoxPro etc.

In 2002, Microsoft combined its products and made .NET framework. Now there is a difference between how code was executed before and how code is managed and executed in .NET framework. Microsoft introduced concept of CLR with .NET framework which compiles the code coming from any supported lanugague of .NET framework and provide additional functionalities like memory mangement, garbage collection etc. But, such CLR features weren't available directly before.

So if you are creating library/code in .NET framework (compiled with CLR) then that is called Managed code. You can use this library further in other .NET application/project, and there too, CLR will understand how it was compiled before, and that's why it remains your manage code.

OTOH if you want to use the libraries that were written prior to .NET framework then you can do with certain limitations, but remember, since CLR wasn't there at that time, so now, CLR won't understand and compile this code again. And this will be called unmanaged code. Please note that, libraries/assembilies created by some third party to provide certain features/tool may also be considered as unmanage code if is not CLR compatiblie.

In laymen terms, Manage code is something which your CLR understands and can compile it on its own for further execution. In .NET framework, (from any language thats work on .NET framework) When code goes to CLR then code supply some meta data information, so that CLR can provide you features specified here. Few of them are Garbage collection, Performance improvements, cross-language integration, memory management etc.

OTOH, unmanged code is something specific to machine and ready to use, no need to process it further.

Try like this as well

covertPostSub("/xyz/test.jsp","?param1=param1&param2=param2","_self","true");
covertPostSub("/xyz/test.jsp","?param1=param1&param2=param2","_blank","true");

var convPop = null;
function covertPostSub(action,paramsTosend,targetIframe,isWindow){
    var Popup = null;
    var form = document.createElement("form");
    form.setAttribute("method", "POST");
    form.setAttribute("id","TheForm");
    form.setAttribute("action", action);
    form.setAttribute("target", targetIframe);
    var params = paramsTosend;
    params = params.substring(1, params.length);
    params = params.split("&");
    for(var key=0; key<params.length; key++) {
        var sa = params[key];
        sa = sa.split("=");
        var xs = (sa[1]);

        if(params.hasOwnProperty(key)) {
            var hiddenField = document.createElement("input");
            hiddenField.setAttribute("type", "hidden");
            hiddenField.setAttribute("name", sa[0]);
            hiddenField.setAttribute("value",xs);

            form.appendChild(hiddenField);
         }
    }
    document.body.appendChild(form);
    form.style.display = "none";
    if(isWindow){
        window.open('', "formpopup","width=900,height=590,toolbar=no,scrollbars=yes,resizable=no,location=0,directories=0,status=1,menubar=0,left=60,top=60");
        form.target = 'formpopup';
        form.submit();
    }else{
        form.submit();
    }

}

Here are a couple: http://www.amp-what.com/unicode/search/check%20mark

&#x2713 &#x2714

volatile is a field modifier, while synchronized modifies code blocks and methods. So we can specify three variations of a simple accessor using those two keywords:

    int i1;
    int geti1() {return i1;}

    volatile int i2;
    int geti2() {return i2;}

    int i3;
    synchronized int geti3() {return i3;}

geti1() accesses the value currently stored in i1 in the current thread. Threads can have local copies of variables, and the data does not have to be the same as the data held in other threads.In particular, another thread may have updated i1 in it's thread, but the value in the current thread could be different from that updated value. In fact Java has the idea of a "main" memory, and this is the memory that holds the current "correct" value for variables. Threads can have their own copy of data for variables, and the thread copy can be different from the "main" memory. So in fact, it is possible for the "main" memory to have a value of 1 for i1, for thread1 to have a value of 2 for i1 and for thread2 to have a value of 3 for i1 if thread1 and thread2 have both updated i1 but those updated value has not yet been propagated to "main" memory or other threads.

On the other hand, geti2() effectively accesses the value of i2 from "main" memory. A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory. Effectively, a variable declared volatile must have it's data synchronized across all threads, so that whenever you access or update the variable in any thread, all other threads immediately see the same value. Generally volatile variables have a higher access and update overhead than "plain" variables. Generally threads are allowed to have their own copy of data is for better efficiency.

There are two differences between volitile and synchronized.

Firstly synchronized obtains and releases locks on monitors which can force only one thread at a time to execute a code block. That's the fairly well known aspect to synchronized. But synchronized also synchronizes memory. In fact synchronized synchronizes the whole of thread memory with "main" memory. So executing geti3() does the following:

1. The thread acquires the lock on the monitor for object this .
2. The thread memory flushes all its variables, i.e. it has all of its variables effectively read from "main" memory .
3. The code block is executed (in this case setting the return value to the current value of i3, which may have just been reset from "main" memory).
4. (Any changes to variables would normally now be written out to "main" memory, but for geti3() we have no changes.)
5. The thread releases the lock on the monitor for object this.

So where volatile only synchronizes the value of one variable between thread memory and "main" memory, synchronized synchronizes the value of all variables between thread memory and "main" memory, and locks and releases a monitor to boot. Clearly synchronized is likely to have more overhead than volatile.

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

What I did (Windows 10) for a new installation:

1. Start cmd in admin mode (run as administrator by hitting windows key, typing cmd, right clicking on it and selecting "Run as Administrator"

2. Change into "MySQL Server X.Y" directory (for me the full path is C:\Program Files\MySQL\MySQL Server 5.7")

3. using notepad create a my.ini with a mysqld section that points at your data directory

   [mysqld]
   datadir="X:\Your Directory Path and Name"
   

4. created the directory identified in my.ini above.

5. change into bin Directory under server directory and execute: mysqld --initialize

6. Once complete, started the service and it came up fine.

Following query will give you the exact table names of the database having field name like '%myName'.

SELECT distinct(TABLE_NAME)
  FROM INFORMATION_SCHEMA.COLUMNS    
 WHERE COLUMN_NAME LIKE '%myName%'

The exact ranges for Chinese characters (except the extensions) are [\u2E80-\u2FD5\u3190-\u319f\u3400-\u4DBF\u4E00-\u9FCC\uF900-\uFAAD].

1. [\u2e80-\u2fd5]

CJK Radicals Supplement is a Unicode block containing alternative, often positional, forms of the Kangxi radicals. They are used headers in dictionary indices and other CJK ideograph collections organized by radical-stroke.

2. [\u3190-\u319f]

Kanbun is a Unicode block containing annotation characters used in Japanese copies of classical Chinese texts, to indicate reading order.

3. [\u3400-\u4DBF]

CJK Unified Ideographs Extension-A is a Unicode block containing rare Han ideographs.

4. [\u4E00-\u9FCC]

CJK Unified Ideographs is a Unicode block containing the most common CJK ideographs used in modern Chinese and Japanese.

5. [\uF900-\uFAAD]

CJK Compatibility Ideographs is a Unicode block created to contain Han characters that were encoded in multiple locations in other established character encodings, in addition to their CJK Unified Ideographs assignments, in order to retain round-trip compatibility between Unicode and those encodings.

For the details please refer to here, and the extensions are provided in other answers.

If you're using WPF there is a LoadCompleted event.

If it's Windows.Forms, the DocumentCompleted event should be the correct one. If the page you're loading has frames, your WebBrowser control will fire the DocumentCompleted event for each frame (see here for more details). I would suggest checking the IsBusy property each time the event is fired and if it is false then your page is fully done loading.

You have a certificate which is self-signed, so it's non-trusted by default, that's why OpenSSL complains. This warning is actually a good thing, because this scenario might also rise due to a man-in-the-middle attack.

To solve this, you'll need to install it as a trusted server. If it's signed by a non-trusted CA, you'll have to install that CA's certificate as well.

Have a look at this link about installing self-signed certificates.

For those out there who still couldn't fix this, I did so by changing my 'this' to '$(this)' when using jQuery.

E.G:

$('.icon').click(function() {
    this.fadeOut();
});

Fixed:

$('.icon').click(function() {
    $(this).fadeOut();
});

I had the same problem.

The solution from depa is absolutely correct.

Just make sure that u have a user configured to use PostgreSQL.

Check the file:

$ ls /etc/postgresql/9.1/main/pg_hba.conf -l

The permission of this file should be given to the user you have registered your psql with.

Further. If you are good till now..

Update as per @depa's instructions.

i.e.

$ sudo nano /etc/postgresql/9.1/main/pg_hba.conf

and then make changes.

To use cache-control in HTML, you use the meta tag, e.g.

<meta http-equiv="Cache-control" content="public">

The value in the content field is defined as one of the four values below.

Some information on the Cache-Control header is as follows

HTTP 1.1. Allowed values = PUBLIC | PRIVATE | NO-CACHE | NO-STORE.

Public - may be cached in public shared caches.
Private - may only be cached in private cache.
No-Cache - may not be cached.
No-Store - may be cached but not archived.

The directive CACHE-CONTROL:NO-CACHE indicates cached information should not be used and instead requests should be forwarded to the origin server. This directive has the same semantics as the PRAGMA:NO-CACHE.

Clients SHOULD include both PRAGMA: NO-CACHE and CACHE-CONTROL: NO-CACHE when a no-cache request is sent to a server not known to be HTTP/1.1 compliant. Also see EXPIRES.

Note: It may be better to specify cache commands in HTTP than in META statements, where they can influence more than the browser, but proxies and other intermediaries that may cache information.

try this instead

Set TxtRng = ActiveWorkbook.Sheets("Game").Range("A1")

ADDITION

Maybe the file is corrupt - this has happened to me several times before and the only solution is to copy everything out into a new file.

Please can you try the following:

• Save a new xlsm file and call it "MyFullyQualified.xlsm"
• Add a sheet with no protection and call it "mySheet"
• Add a module to the workbook and add the following procedure

Does this run?

 Sub varchanger()

 With Excel.Application
    .ScreenUpdating = True
    .Calculation = Excel.xlCalculationAutomatic
    .EnableEvents = True
 End With

 On Error GoTo Whoa:

    Dim myBook As Excel.Workbook
    Dim mySheet As Excel.Worksheet
    Dim Rng  As Excel.Range

    Set myBook = Excel.Workbooks("MyFullyQualified.xlsm")
    Set mySheet = myBook.Worksheets("mySheet")
    Set Rng = mySheet.Range("A1")

    'ActiveSheet.Unprotect


    Rng.Value = "SubTotal"

    Excel.Workbooks("MyFullyQualified.xlsm").Worksheets("mySheet").Range("A1").Value = "Asdf"

LetsContinue:
        Exit Sub

If the div has some content inside, this will be the best practice to have a line over or under the div and maintaining the content spacing with the div

.div_line_bottom{
 border-bottom: 1px solid #ff0000;
 padding-bottom:20px;
}

.div_line_top{
border-top: 1px solid #ff0000;
padding-top:20px;
}

try c_x freeze it can create a good standalone

* Please Note: as of v0.9 the set and get API has been deprecated *

The following code should only be used for version socket.io < 0.9
See: http://socket.io/docs/migrating-from-0-9/

It can be done through the handshake/authorization mechanism.

var cookie = require('cookie');
io.set('authorization', function (data, accept) {
    // check if there's a cookie header
    if (data.headers.cookie) {
        // if there is, parse the cookie
        data.cookie = cookie.parse(data.headers.cookie);
        // note that you will need to use the same key to grad the
        // session id, as you specified in the Express setup.
        data.sessionID = data.cookie['express.sid'];
    } else {
       // if there isn't, turn down the connection with a message
       // and leave the function.
       return accept('No cookie transmitted.', false);
    }
    // accept the incoming connection
    accept(null, true);
});

All the attributes, that are assigned to the data object are now accessible through the handshake attribute of the socket.io connection object.

io.sockets.on('connection', function (socket) {
    console.log('sessionID ' + socket.handshake.sessionID);
});

finally, I found a solution

 Window window =   ((Node)(event.getSource())).getScene().getWindow(); 
            if (window instanceof Stage){
                ((Stage) window).close();
            }

CREATE GLOBAL TEMPORARY TABLE Table_name
    (startdate DATE,
     enddate DATE,
     class CHAR(20))
  ON COMMIT DELETE ROWS;

The issue is not with the with statement, it is on the Range function, it doesn't accept the absolute cell value.. it should be like Range("A4:B100").. you can refer the following thread for reference..

following code should work.. Convert cells(1,1) into "A1" and vice versa

LastColData = Sheets(WSNAME).Range("A4").End(xlToRight).Column
            LastRowData = Sheets(WSNAME).Range("A4").End(xlDown).Row
            Rng = "A4:" & Sheets(WSNAME).Cells(LastRowData, LastColData).Address(RowAbsolute:=False, ColumnAbsolute:=False)

 Worksheets(WSNAME).Range(Rng).ClearContents

You can use Visual Studio Team Services for free. Also you can import a TFS repo to this cloud space.

This is probably caused by having multiple SSH keys in SSH agent (and/or BitBucket). Check Atlassian documentation for the workaround for this

The problem here is that you have two different languages that solve two different problems... its like comparing C++ with assembler.

Python is for rapid application development and for when performance is a minimal concern.

C++ is not for rapid application development and inherits a legacy of speed from C - for low level programming.

jQuery will do the job. You can use either jQuery.ajax function, which is general one for performing ajax calls, or its wrappers: jQuery.get, jQuery.post for getting/posting data. Its very easy to use, for example, check out this tutorial, which shows how to use jQuery with PHP.

1. Parse the JSON

const arr = JSON.parse(json);

2. For each object in the JSON, rename the key:

obj.id = obj._id;
delete obj._id;

3. Stringify the result

function renameKey ( obj, oldKey, newKey ) {
  obj[newKey] = obj[oldKey];
  delete obj[oldKey];
}

const json = `
  [
    {

uint16_t is unsigned 16-bit integer.

unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX is 65535). In practice, it usually is 16-bit, but you can't take that as guaranteed.

Note:

1. If you want a portable unsigned 16-bit integer, use uint16_t.
2. inttypes.h and stdint.h are both introduced in C99. If you are using C89, define your own type.
3. uint16_t may not be provided in certain implementation(See reference below), but unsigned short int is always available.

Reference: C11(ISO/IEC 9899:201x) §7.20 Integer types

For each type described herein that the implementation provides) shall declare that typedef name and define the associated macros. Conversely, for each type described herein that the implementation does not provide, shall not declare that typedef name nor shall it define the associated macros. An implementation shall provide those types described as ‘‘required’’, but need not provide any of the others (described as ‘optional’’).

Use Apache commons StringUtils.join(). It takes an array, as a parameter (and also has overloads for Iterable and Iterator parameters) and calls toString() on each element (if it is not null) to get each elements string representation. Each elements string representation is then joined into one string with a separator in between if one is specified:

String joinedString = StringUtils.join(new Object[]{"a", "b", 1}, "-");
System.out.println(joinedString);

Produces:

a-b-1

        android:layout_weight="1"
        android:background="@drawable/roundlayoutbutton1"
        android:ems="10"
        android:gravity="center"
        android:inputType="text"
        android:textAllCaps="true"
        android:text="search_xxxx"

        android:textColor="@color/colorPrimaryDark"
        android:visibility="visible" />

and in java class you may have below one :

    EditText searchHost;

OnCreate() you write:

    searchHost=findViewById(R.id.txtsearch);

    searchHost.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(searchHost.getText().toString().equalsIgnoreCase("search_xxxx")){
                searchHost.setText("");
                Toast.makeText(getApplicationContext(),"Enter you text xxx...", Toast.LENGTH_LONG).show();
            }
        }
    });

It works fine for me.

List of One Liners

Let's solve this problem for this array:

var array = ['A', 'B', 'C'];

1. Remove only the first: Use If you are sure that the item exist

array.splice(array.indexOf('B'), 1);

2. Remove only the last: Use If you are sure that the item exist

array.splice(array.lastIndexOf('B'), 1);

3. Remove all occurrences:

array = array.filter(v => v !== 'B'); 

From Git v1.7.8 to v1.8.5.6, you can use this:

git fetch <remote> --prune --tags

Update

This doesn't work on newer versions of git (starting with v1.9.0) because of commit e66ef7ae6f31f2. I don't really want to delete it though since it did work for some people.

As suggested by "Chad Juliano", with all Git version since v1.7.8, you can use the following command:

git fetch --prune <remote> +refs/tags/*:refs/tags/*

You may need to enclose the tags part with quotes (on Windows for example) to avoid wildcard expansion:

git fetch --prune <remote> "+refs/tags/*:refs/tags/*"

use this:

adb logcat -s "TAGNAME"

Url.Action("Evil", model)

will generate a get query string but your ajax method is post and it will throw error status of 500(Internal Server Error). – Fereydoon Barikzehy Feb 14 at 9:51

Just Add "JsonRequestBehavior.AllowGet" on your Json object.

If you just want something simple:

'$' . number_format($money, 2);

number_format()

There is no portable way to do this, but select() might be a good way. See http://c-faq.com/osdep/readavail.html for more possible solutions.

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

This worked for me:

On terminal type the following

$ sudo mysql -u root -p

Enter password://just press enter

I had the same problem. I'm using DB2. What I have done is a bit not too professional solution, but it works in every DBMS:

1. Add a column with the same definition without the unique contraint.
2. Copy the values from the original column to the new
3. Drop the original column (so DBMS will remove the constraint as well no matter what its name was)
4. And finally rename the new one to the original
5. And a reorg at the end (only in DB2)

ALTER TABLE USERS ADD COLUMN LOGIN_OLD VARCHAR(50) NOT NULL DEFAULT '';
UPDATE USERS SET LOGIN_OLD=LOGIN;
ALTER TABLE USERS DROP COLUMN LOGIN;
ALTER TABLE USERS RENAME COLUMN LOGIN_OLD TO LOGIN;

CALL SYSPROC.ADMIN_CMD('REORG TABLE USERS');

The syntax of the ALTER commands may be different in other DBMS

When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:

select *
from little
left join big
on left( big.key, len(little.key) ) = little.key

I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.

Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.

This one worked for me.

if you have a hive setup you can put the local dataset directly using Hive load command in hdfs/s3.

You will need to use "Local" keyword when writing your load command.

Syntax for hiveload command

LOAD DATA [LOCAL] INPATH 'filepath' [OVERWRITE] INTO TABLE tablename [PARTITION (partcol1=val1, partcol2=val2 ...)]

Refer below link for more detailed information. https://cwiki.apache.org/confluence/display/Hive/LanguageManual%20DML#LanguageManualDML-Loadingfilesintotables

Here's one way. The inner query gets the max date for each id. Then you can join that back to your main table to get the rows that match.

select
*
from
<your table>
inner join 
(select id, max(<date col> as max_date) m
where yourtable.id = m.id
and yourtable.datecolumn = m.max_date)

There is a lot more to coalesce than just a replacement for ISNULL. I completely agree that the official "documentation" of coalesce is vague and unhelpful. This article helps a lot. http://www.mssqltips.com/sqlservertip/1521/the-many-uses-of-coalesce-in-sql-server/

As with C, ultimately, everything is passed by value. Unlike C, you can't actually back up and pass the location of a variable, because it doesn't have pointers, just references.

And the references it has are all to objects, not variables. There are several ways of achieving the same result, but they have to be done by hand, not just adding a keyword at either the call or declaration site.

Retaining all questions ids with small tweak

Map<Integer, Boolean> answerMap = 
  answerList.stream()
            .collect(Collectors.toMap(Answer::getId, a -> 
                       Boolean.TRUE.equals(a.getAnswer())));

In Preferences, select Python Interpreter

Under Python Interpreter, change from "Default" to "Use the following Python interpreter"

The path there should be the default Python executable. Find your Python 2.7 executable and use that.

Sometimes getBoundingClientRect() object's property value shows 0 for IE. In that case you have to set display = 'block' for the element. You can use below code for all browser to get offset.

Extend jQuery functionality :

(function($) {
    jQuery.fn.weOffset = function () {
        var de = document.documentElement;
        $(this).css("display", "block");
        var box = $(this).get(0).getBoundingClientRect();
        var top = box.top + window.pageYOffset - de.clientTop;
        var left = box.left + window.pageXOffset - de.clientLeft;
        return { top: top, left: left };
    };
}(jQuery));

Use :

var elementOffset = $("#" + elementId).weOffset();

seems ok... though I'd think a rudimentary indication of success/failure/time posted/# bytes received/etc. would be preferable.

edit: I was thinking along the lines of data integrity and/or record-keeping; metadata such as an MD5 hash or timestamp for time received may be helpful for large datafiles.

This function:

• "Proper Cases" all "UPPER CASE" words that are delimited by white space
• leaves "lower case words" alone
• works properly even for non-English alphabets
• is portable in that it does not use fancy features of recent SQL server versions
• can be easily changed to use NCHAR and NVARCHAR for unicode support,as well as any parameter length you see fit
• white space definition can be configured

CREATE FUNCTION ToProperCase(@string VARCHAR(255)) RETURNS VARCHAR(255)
AS
BEGIN
  DECLARE @i INT           -- index
  DECLARE @l INT           -- input length
  DECLARE @c NCHAR(1)      -- current char
  DECLARE @f INT           -- first letter flag (1/0)
  DECLARE @o VARCHAR(255)  -- output string
  DECLARE @w VARCHAR(10)   -- characters considered as white space

  SET @w = '[' + CHAR(13) + CHAR(10) + CHAR(9) + CHAR(160) + ' ' + ']'
  SET @i = 1
  SET @l = LEN(@string)
  SET @f = 1
  SET @o = ''

  WHILE @i <= @l
  BEGIN
    SET @c = SUBSTRING(@string, @i, 1)
    IF @f = 1 
    BEGIN
     SET @o = @o + @c
     SET @f = 0
    END
    ELSE
    BEGIN
     SET @o = @o + LOWER(@c)
    END

    IF @c LIKE @w SET @f = 1

    SET @i = @i + 1
  END

  RETURN @o
END

Result:

dbo.ToProperCase('ALL UPPER CASE and    SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ CC ÆÆ')
-----------------------------------------------------------------
All Upper Case and      Some lower Ää Öö Üü Éé Øø Cc Ææ

List.indexOf() will give you what you want, provided you know precisely what you're after, and provided that the equals() method for Party is well-defined.

Party searchCandidate = new Party("FirstParty");
int index = cave.parties.indexOf(searchCandidate);

This is where it gets interesting - subclasses shouldn't be examining the private properties of their parents, so we'll define equals() in the superclass.

@Override
public boolean equals(Object o) {
    if (this == o) {
        return true;
    }
    if (!(o instanceof CaveElement)) {
        return false;
    }

    CaveElement that = (CaveElement) o;

    if (index != that.index) {
        return false;
    }
    if (name != null ? !name.equals(that.name) : that.name != null) {
        return false;
    }

    return true;
}

It's also wise to override hashCode if you override equals - the general contract for hashCode mandates that, if x.equals(y), then x.hashCode() == y.hashCode().

@Override
public int hashCode() {
    int result = name != null ? name.hashCode() : 0;
    result = 31 * result + index;
    return result;
}

bin(int("abc123efff", 16))[2:]

Short answer: No.

But you might be able to do it with a bit of filthing. If you open up a test page (with GET) then evaluate some JavaScript on that page you should be able to replicate a POST request. See JavaScript post request like a form submit to see how you can replicate a POST request in JavaScript.

Hope this helps.

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

DECLARE @sql VARCHAR(MAX)
SET @sql=''
SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects
WHERE type = 'p' AND  is_ms_shipped = 0
exec(@sql);

Boost multindex can be used for proper solution. Following solution is not a very best option but might be useful in few cases where user is assigning default value like 0 or NULL at initialization and want to check if value has been modified.

Ex.
< int , string >
< string , int > 
< string , string > 

consider < string , string >
mymap["1st"]="first";
mymap["second"]="";
for (std::map<string,string>::iterator it=mymap.begin(); it!=mymap.end(); ++it)
{
       if ( it->second =="" ) 
            continue;
}

This works well for me.

SHOW COLUMNS FROM `table` LIKE 'fieldname';

With PHP it would be something like...

$result = mysql_query("SHOW COLUMNS FROM `table` LIKE 'fieldname'");
$exists = (mysql_num_rows($result))?TRUE:FALSE;

Take a look at the write.csv or the write.table functions. You just have to supply the file name the user selects to the file parameter, and the dataframe to the x parameter:

write.csv(x=df, file="myFileName")

You could do something like this:

$("span, p").each(function() {
    var text = $(this).text();
    text = text.replace("lollypops", "marshmellows");
    $(this).text(text);
});

It will be better to mark all tags with text that needs to be examined with a suitable class name.

Also, this may have performance issues. jQuery or javascript in general aren't really suitable for this kind of operations. You are better off doing it server side.

Using the join operator you can only perform equijoins. Other types of joins can be constructed using other operators. I'm not sure whether the exact join you are trying to do would be easier using these methods or by changing the where clause. Documentation on the join clause can be found here. MSDN has an article on join operations with multiple links to examples of other joins, as well.

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

Example

To add a little bit more information that confused me; I had always thought the same result could be achieved like so;

theDate.ToString("yyyy-MM-dd HH:mm:ss")

However, If your Current Culture doesn't use a colon(:) as the hour separator, and instead uses a full-stop(.) it could return as follow:

2009-06-15 13.45.30

Just wanted to add why the answer provided needs to be as it is;

theDate.ToString("yyyy-MM-dd HH':'mm':'ss")

I agree with Sam and Xaser and have actually taken this a bit farther. I don't think you should be implementing the INotifyPropertyChanged interface in a UserControl at all...the control is already a DependencyObject and therefore already comes with notifications. Adding INotifyPropertyChanged to a DependencyObject is redundant and "smells" wrong to me.

What I did is implement both properties as DependencyProperties, as Sam suggests, but then simply had the PropertyChangedCallback from the "first" dependency property alter the value of the "second" dependency property. Since both are dependency properties, both will automatically raise change notifications to any interested subscribers (e.g. data binding etc.)

In this case, dependency property A is the string InviteText, which triggers a change in dependency property B, the Visibility property named ShowInvite. This would be a common use case if you have some text that you want to be able to hide completely in a control via data binding.

public string InviteText  
{
    get { return (string)GetValue(InviteTextProperty); }
    set { SetValue(InviteTextProperty, value); }
}

public static readonly DependencyProperty InviteTextProperty =
    DependencyProperty.Register("InviteText", typeof(string), typeof(InvitePrompt), new UIPropertyMetadata(String.Empty, OnInviteTextChanged));

private static void OnInviteTextChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
    InvitePrompt prompt = d as InvitePrompt;
    if (prompt != null)
    {
        string text = e.NewValue as String;
        prompt.ShowInvite = String.IsNullOrWhiteSpace(text) ? Visibility.Collapsed : Visibility.Visible;
    }
}

public Visibility ShowInvite
{
    get { return (Visibility)GetValue(ShowInviteProperty); }
    set { SetValue(ShowInviteProperty, value); }
}

public static readonly DependencyProperty ShowInviteProperty =
    DependencyProperty.Register("ShowInvite", typeof(Visibility), typeof(InvitePrompt), new PropertyMetadata(Visibility.Collapsed));

Note I'm not including the UserControl signature or constructor here because there is nothing special about them; they don't need to subclass from INotifyPropertyChanged at all.

You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:

FormBorderStyle    FixedToolWindow
ShowInTaskBar      False
StartPosition      CenterScreen

To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:

MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
    // etc
}

It would be advisable to add your own Show method that takes the text and other options you require:

public DialogResult Show(string text, Color foreColour)
{
     lblText.Text = text;
     lblText.ForeColor = foreColour;
     return this.ShowDialog();
}

Arrays.asList is the handy function available in Java to convert an array variable to List or Collection. For better under standing consider the below example:

package com.stackoverflow.works;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Wetland {
    private String name;
    private List<String> species = new ArrayList<String>();

    public Wetland(String name, String[] speciesArr) {
        this.name = name;
        this.species = Arrays.asList(speciesArr);
    }

    public void display() {
        System.out.println("Name: " + name);
        System.out.println("Elements in the List");
        System.out.println("********************");
        for (String string : species) {
            System.out.println(string);
        }
    }

    /*
     * @Description: Method to test your code
     */
    public static void main(String[] args) {
        String name = "Colors";
        String speciesArr[] = new String [] {"red", "blue", "green"};
        Wetland wetland = new Wetland(name, speciesArr);
        wetland.display();
    }

}

Output:

To resolve the issue on a Debian/Ubuntu system modify the /etc/apache2/ports.conf settings file by adding NameVirtualHost *:443 to it. My ports.conf is the following at the moment:

# /etc/apache/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.

    NameVirtualHost *:443

    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

Furthermore ensure that 'sites-available/default-ssl' is not enabled, type a2dissite default-ssl to disable the site. While you're at it type a2dissite by itself to get a list and see if there is any other site settings that you have enabled that might be mapping onto port 443.

Addition to the Usage from the ORM layer in the accepted answer: count(*) can be done for ORM using the query.with_entities(func.count()), like this:

session.query(MyModel).with_entities(func.count()).scalar()

It can also be used in more complex cases, when we have joins and filters - the important thing here is to place with_entities after joins, otherwise SQLAlchemy could raise the Don't know how to join error.

For example:

• we have User model (id, name) and Song model (id, title, genre)
• we have user-song data - the UserSong model (user_id, song_id, is_liked) where user_id + song_id is a primary key)

We want to get a number of user's liked rock songs:

SELECT count(*) 
  FROM user_song
  JOIN song ON user_song.song_id = song.id 
 WHERE user_song.user_id = %(user_id)
   AND user_song.is_liked IS 1
   AND song.genre = 'rock'

This query can be generated in a following way:

user_id = 1

query = session.query(UserSong)
query = query.join(Song, Song.id == UserSong.song_id)
query = query.filter(
    and_(
        UserSong.user_id == user_id, 
        UserSong.is_liked.is_(True),
        Song.genre == 'rock'
    )
)
# Note: important to place `with_entities` after the join
query = query.with_entities(func.count())
liked_count = query.scalar()

Simple excel file create in mvc 4

public ActionResult results() { return File(new System.Text.UTF8Encoding().GetBytes("string data"), "application/csv", "filename.csv"); }

Give this a try:

foreach (PropertyInfo propertyInfo in obj.GetType().GetProperties())
{
   // do stuff here
}

Also please note that Type.GetProperties() has an overload which accepts a set of binding flags so you can filter out properties on a different criteria like accessibility level, see MSDN for more details: Type.GetProperties Method (BindingFlags) Last but not least don't forget to add the "system.Reflection" assembly reference.

For instance to resolve all public properties:

foreach (var propertyInfo in obj.GetType()
                                .GetProperties(
                                        BindingFlags.Public 
                                        | BindingFlags.Instance))
{
   // do stuff here
}

Please let me know whether this works as expected.

I was having a problem with ASP.NET MVC 5 where CheckBoxFor would not check my checkboxes on server-side validation failure even though my model clearly had the value set to true. My Razor markup/code looked like:

@Html.CheckBoxFor(model => model.MyBoolValue, new { @class = "mySpecialClass" } )

To get this to work, I had to change this to:

@{
    var checkboxAttributes = Model.MyBoolValue ?
        (object) new { @class = "mySpecialClass", @checked = "checked" } :
        (object) new { @class = "mySpecialClass" };
}
@Html.CheckBox("MyBoolValue", checkboxAttributes)

I have implemented data downloading functionality through FTP server and found the same exception there too while resuming that download. To resolve this exception, you will always have to disconnect from the previous session and create new instance of the Client and new connection with the server. This same approach could be helpful for HTTPClient too.

As you are using SQL Server 2008, go with Martin's answer.

If you find yourself needing to do it in SQL Server 2005 where you don't have access to the Date column type, I'd use:

Why not change the orders of the tags? Your HTML page isn't made out of stone, are they?

If the <div> has id or name then you can use find_element_by_id or find_element_by_name

The first solution is to use the java.util.Random class:

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Another solution is using Math.random():

double random = Math.random() * 49 + 1;

or

int random = (int)(Math.random() * 50 + 1);

I have managed to write a script allowing the user to choose his/her language, using the cookie script from Klaus Hartl. It took me a few hours work, and I hope I can help others.

If you intend to use it for realtime system, perhaps java isnt the best choice to get the timestamp. But if youre going to use if for unique key, then Jason Smith's answer will do enough. But just in case, to anticipate 2 item end up getting the same timestamp (its possible if those 2 were processed almost simultaneously), you can loop until the last timestamp not equals with the current timestamp.

String timestamp = new String();
do {
    timestamp = String.valueOf(MicroTimestamp.INSTANCE.get());
    item.setTimestamp(timestamp);
} while(lasttimestamp.equals(timestamp));
lasttimestamp = item.getTimestamp();

A primitive method would be:

var obj = {};

for ( var i=0, len=things.thing.length; i < len; i++ )
    obj[things.thing[i]['place']] = things.thing[i];

things.thing = new Array();
for ( var key in obj )
    things.thing.push(obj[key]);

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

As far as I know Angular-cli file can't be created via a command like Package-lock file, If you want to create it, you have to do it manually.

1. You can type ng new to create a new angular project

2. Locate its .angular-cli.json file

3. Copy all its content

4. Create a folder in your original project, and name it .angular-cli.json

5. Paste what copied from new project in newly created angular cli file of original project.

6. Locate this line in angular cli file you created, and change the name field to original project's name. You can find the project name in package.json file

project": {
  "name": "<name of the project>"
},

However, in newer angular version now it uses angular.json instead of angular-cli.json.

As easy as it seems

$skuList = explode('\\n', $_POST['skuList']);

You just need to pass the exact text "\n" and writing \n directly is being used as an Escape Sequence. So "\\" to pass a simple backward slash and then put "n"

If you find this answer useful, you may be interested in a simple (~500 SLOC) password generation library I published:

Install-Package MlkPwgen

Then you can generate random strings just like in the answer below:

var str = PasswordGenerator.Generate(length: 10, allowed: Sets.Alphanumerics);

One advantage of the library is that the code is better factored out so you can use secure randomness for more than generating strings. Check out the project site for more details.

Original Answer

Since no one has provided secure code yet, I post the following in case anyone finds it useful.

string RandomString(int length, string allowedChars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789") {
    if (length < 0) throw new ArgumentOutOfRangeException("length", "length cannot be less than zero.");
    if (string.IsNullOrEmpty(allowedChars)) throw new ArgumentException("allowedChars may not be empty.");

    const int byteSize = 0x100;
    var allowedCharSet = new HashSet<char>(allowedChars).ToArray();
    if (byteSize < allowedCharSet.Length) throw new ArgumentException(String.Format("allowedChars may contain no more than {0} characters.", byteSize));

    // Guid.NewGuid and System.Random are not particularly random. By using a
    // cryptographically-secure random number generator, the caller is always
    // protected, regardless of use.
    using (var rng = System.Security.Cryptography.RandomNumberGenerator.Create()) {
        var result = new StringBuilder();
        var buf = new byte[128];
        while (result.Length < length) {
            rng.GetBytes(buf);
            for (var i = 0; i < buf.Length && result.Length < length; ++i) {
                // Divide the byte into allowedCharSet-sized groups. If the
                // random value falls into the last group and the last group is
                // too small to choose from the entire allowedCharSet, ignore
                // the value in order to avoid biasing the result.
                var outOfRangeStart = byteSize - (byteSize % allowedCharSet.Length);
                if (outOfRangeStart <= buf[i]) continue;
                result.Append(allowedCharSet[buf[i] % allowedCharSet.Length]);
            }
        }
        return result.ToString();
    }
}

my 2¢ quick global fix:

// drop down in responsive table

(function () {
  $('.table-responsive').on('shown.bs.dropdown', function (e) {
    var $table = $(this),
        $menu = $(e.target).find('.dropdown-menu'),
        tableOffsetHeight = $table.offset().top + $table.height(),
        menuOffsetHeight = $menu.offset().top + $menu.outerHeight(true);

    if (menuOffsetHeight > tableOffsetHeight)
      $table.css("padding-bottom", menuOffsetHeight - tableOffsetHeight);
  });

  $('.table-responsive').on('hide.bs.dropdown', function () {
    $(this).css("padding-bottom", 0);
  })
})();

Explications: When a dropdown-menu inside a '.table-responsive' is shown, it calculate the height of the table and expand it (with padding) to match the height required to display the menu. The menu can be any size.

In my case, this is not the table that has the '.table-responsive' class, it's a wrapping div:

<div class="table-responsive" style="overflow:auto;">
    <table class="table table-hover table-bordered table-condensed server-sort">

So the $table var in the script is actually a div! (just to be clear... or not) :)

Note: I wrap it in a function so my IDE can collapse function ;) but it's not mandatory!

var array: Int[][] = [[1,2,3],[4,5,6],[7,8,9]]

for first in array {
    for second in first {
        println("value \(second)")
    }
}

To achieve what you're looking for you need to initialize the array to the correct template and then loop to add the row and column arrays:

var NumColumns = 27
var NumRows = 52
var array = Array<Array<Int>>()
var value = 1

for column in 0..NumColumns {
    var columnArray = Array<Int>()
    for row in 0..NumRows {
        columnArray.append(value++)
    }
    array.append(columnArray)
}

println("array \(array)")

Just a note, on Linux You can simply run sudo su - postgres to become the postgres user and from there change what required using psql.

Your code has lots of errors.

• You are mixing up dm$Day and dm$day. Probably not the same thing
• Your column headings are Date and Visits. So you would access them (I'm guessing) as dm$Date and dm$Visits
• In the date field you have %Y-%m-%d this should be %m/%d/%Y

The following code should plot what you want:

dm$newday = as.Date(dm$Date, "%m/%d/%Y")
plot(dm$newday, dm$Visits)

What about using the following:

int number = input.nextInt();
if (number < 0) {
    // negative
} else {
   // it's a positive
}

You can do this with the Box component:

import Box from "@material-ui/core/Box";

...

<Box
  display="flex"
  justifyContent="center"
  alignItems="center"
  minHeight="100vh"
>
  <YourComponent/>
</Box>

Try this:

apt-get install lib32stdc++6

There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.

When you define your list as:

List myList = new ArrayList();

you can only call methods and reference members that are defined in the List interface. If you define it as:

ArrayList myList = new ArrayList();

you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.

Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).

That's called polymorphism. You can read up on it.

First of all, this what is written in documentation. I think it is one of your class fields, not the main one - and how you want deserialiser to construct it back w/o parameterless construction ?

I think there is a workaround to make constructor private.

body: Container(
    decoration: BoxDecoration(
      image: DecorationImage(
        image: AssetImage('images/background.png'),fit:BoxFit.cover
      )
    ),
);

You can't override a static method, so making it abstract would be meaningless. Moreover, a static method in an abstract class would belong to that class, and not the overriding class, so couldn't be used anyway.

I'm sure it some combination of the other things mentioned here like allowing clear text, which I enabled for localhost. But this was the final piece in the puzzle.

It is however available in Safari and Chrome. Since you mention Chrome I'll use that for my example.

You'll need to open your window and its developer window counterpart. you can do this by right clicking any element on the page and selecting "Inspect element". your window will be divided in two parts, the developer part being the bottom. in the division between the two parts is a bar with buttons and the rightmost button there is labeled "console". You'll need to click that to switch to the console tab. Press F12 for developer tools in most browsers on Windows, command + shift + I on macOS.

Once there, you will be able to interact with whatever page is loaded on top through javascript from that console, and any messages you console.log will be displayed there.

I know, this thread is very old. Having read all above posts, I would like to add one more idea to handle this in a neat way: If you get into the mapping business anyway (mapping pthread_to to an int), you could as well go one step further in readability. Make your pthread_create_wrapper such that it takes a string, too...the name of the thread. I learned to appreciate this "SetThreadName()" feature on windows and windows CE. Advantages: Your ids are not just numbers but you also see, which of your threads has which purpose.

You can also use awk:

awk 'END {print NR,"lines"}' filename

Or

awk 'END {print NR}' filename

Try numpy.array_split.

From the documentation:

>>> x = np.arange(8.0)
>>> np.array_split(x, 3)
    [array([ 0.,  1.,  2.]), array([ 3.,  4.,  5.]), array([ 6.,  7.])]

Identical to numpy.split, but won't raise an exception if the groups aren't equal length.

If number of chunks > len(array) you get blank arrays nested inside, to address that - if your split array is saved in a, then you can remove empty arrays by:

[x for x in a if x.size > 0]

Just save that back in a if you wish.

You have to disable the sandbox for Groovy in your job configuration.

Currently this is not possible for multibranch projects where the groovy script comes from the scm. For more information see https://issues.jenkins-ci.org/browse/JENKINS-28178

You need to set the Identity seed to that value:

CREATE TABLE orders

)

To alter an existing table:

ALTER TABLE orders ALTER COLUMN Id INT IDENTITY (9586, 1);

Get the version of Boost that you require. This is for 1.55 but feel free to change or manually download yourself:

wget -O boost_1_55_0.tar.gz https://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz/download
tar xzvf boost_1_55_0.tar.gz
cd boost_1_55_0/

Get the required libraries, main ones are icu for boost::regex support:

sudo apt-get update
sudo apt-get install build-essential g++ python-dev autotools-dev libicu-dev libbz2-dev libboost-all-dev

Boost's bootstrap setup:

./bootstrap.sh --prefix=/usr/

Then build it with:

./b2

and eventually install it:

sudo ./b2 install

You can change using the .bat make sure you run the call command prior, hopefully this helps anyone in future making similar .bat commands

call npm config set registry https://registry.npmjs.org/

You could take the regex that validates YYYY/MM/DD and flip it around to get what you need for DD/MM/YYYY:

/^(0?[1-9]|[12][0-9]|3[01])[\/\-](0?[1-9]|1[012])[\/\-]\d{4}$/

BTW - this regex validates for either DD/MM/YYYY or DD-MM-YYYY

P.S. This will allow dates such as 31/02/4899

I think there is a semantic problem here. In my view, a user can have a (but only one) favourite recipe to prepare a specific menu. (The OP has menu and recipe mixed up; if I am wrong: please interchange MenuId and RecipeId below) That implies that {user,menu} should be a unique key in this table. And it should point to exactly one recipe. If the user has no favourite recipe for this specific menu no row should exist for this {user,menu} key pair. Also: the surrogate key (FaVouRiteId) is superfluous: composite primary keys are perfectly valid for relational-mapping tables.

That would lead to the reduced table definition:

CREATE TABLE Favorites
( UserId uuid NOT NULL REFERENCES users(id)
, MenuId uuid NOT NULL REFERENCES menus(id)
, RecipeId uuid NOT NULL REFERENCES recipes(id)
, PRIMARY KEY (UserId, MenuId)
);

To produce patch for several commits, you should use format-patch git command, e.g.

git format-patch -k --stdout R1..R2

This will export your commits into patch file in mailbox format.

To generate patch for the last commit, run:

git format-patch -k --stdout HEAD^

Then in another repository apply the patch by am git command, e.g.

git am -3 -k file.patch

See: man git-format-patch and git-am.

If you just want to log the list of elements, you can use the list toString() method which already concatenates all the list elements.

You have to use a Class instance because of the generic type erasure during compilation.

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
    try {
        return clazz.cast(o);
    } catch(ClassCastException e) {
        return null;
    }
}

The declaration of that method is:

public T cast(Object o)

This can also be used for array types. It would look like this:

final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);

Note that when someObject is passed to convertToInstanceOfObject it has the compile time type Object.

As soon as I saw the problem statement, I thought "Trie". But seeing as several other posters made use of that approach, I looked for another approach just to be different. Alas, the Trie approach performs better. I ran Kent's Perl solution on my machine and it took 0.31 seconds to run, after adapting it to use my dictionary file. My own perl implementation required 0.54 seconds to run.

This was my approach:

1. Create a transition hash to model the legal transitions.

2. Iterate through all 16^3 possible three letter combinations.

   • In the loop, exclude illegal transitions and repeat visits to the same square. Form all the legal 3-letter sequences and store them in a hash.

3. Then loop through all words in the dictionary.

   • Exclude words that are too long or short
   • Slide a 3-letter window across each word and see if it is among the 3-letter combos from step 2. Exclude words that fail. This eliminates most non-matches.
   • If still not eliminated, use a recursive algorithm to see if the word can be formed by making paths through the puzzle. (This part is slow, but called infrequently.)

4. Print out the words I found.

   I tried 3-letter and 4-letter sequences, but 4-letter sequences slowed the program down.

In my code, I use /usr/share/dict/words for my dictionary. It comes standard on MAC OS X and many Unix systems. You can use another file if you want. To crack a different puzzle, just change the variable @puzzle. This would be easy to adapt for larger matrices. You would just need to change the %transitions hash and %legalTransitions hash.

The strength of this solution is that the code is short, and the data structures simple.

Here is the Perl code (which uses too many global variables, I know):

The following snippet gives an example that shows how to get an element from a List at a specified index, and also how to use the advanced for-each loop to iterate through all elements:

    import java.util.*;

    //...

    List<String> list = new ArrayList<String>();
    list.add("Hello!");
    list.add("How are you?");

    System.out.println(list.get(0)); // prints "Hello!"

    for (String s : list) {
        System.out.println(s);
    } // prints "Hello!", "How are you?"

Note the following:

• Generic List<String> and ArrayList<String> types are used instead of raw ArrayList type.
• Variable names starts with lowercase
• list is declared as List<String>, i.e. the interface type instead of implementation type ArrayList<String>.

References

• Java Collections Framework tutorial
• class ArrayList<E> implements List<E>
• interface List<E>
  • E get(int index)
    • Returns the element at the specified position in this list.

Don't use raw types

• JLS 4.8 Raw Types

  The use of raw types is allowed only as a concession to compatibility of legacy code. The use of raw types in code written after the introduction of genericity into the Java programming language is strongly discouraged. It is possible that future versions of the Java programming language will disallow the use of raw types.

• Effective Java 2nd Edition: Item 23: Don't use raw types in new code

  If you use raw types, you lose all the safety and expressiveness benefits of generics.

Prefer interfaces to implementation classes in type declarations

• Effective Java 2nd Edition: Item 52: Refer to objects by their interfaces

  [...] you should favor the use of interfaces rather than classes to refer to objects. If appropriate interface types exist, then parameters, return values, variables, and fields should all be declared using interface types.

Naming conventions

Variables: Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter.

If the separators are ':', you can split on ':', and then use x.strip() on the strings to get rid of any leading or trailing whitespace. int() will ignore the spaces.

I had the same problem.

In fact, this is a retro-gradation of Python3 as compared to Python2. Certainly, Python2 which uses range() and xrange() is more convenient than Python3 which uses list(range()) and range() respectively. The reason is because the original designer of Python3 is not very experienced, they only considered the use of the range function by many beginners to iterate over a large number of elements where it is both memory and CPU inefficient; but they neglected the use of the range function to produce a number list. Now, it is too late for them to change back already.

If I was to be the designer of Python3, I will:

1. use irange to return a sequence iterator
2. use lrange to return a sequence list
3. use range to return either a sequence iterator (if the number of elements is large, e.g., range(9999999) or a sequence list (if the number of elements is small, e.g., range(10))

That should be optimal.

C# code can be split between lines on pretty much any syntatic construct without a need for a '_' style construct.

For example

foo.
 Bar(
   42
 , "again");

For those that are still experiencing problems, like I have(I am using Ubuntu 16.04), I had to put in the following commands in order to get some gems like bcrypt, pg, and others installed. They are all similar to the ones above except for one.

sudo apt-get install ruby-dev -y
sudo apt-get install libpq-dev -y
sudo apt-get install libmysqlclient-dev
sudo apt-get install build-essential patch -y

This allowed me to install gems like, PG, bcrypt, and recaptcha.

By changing runProguard to minifyEnabled, part of the issue gets fixed.

But the fix can cause "Library Projects cannot set application Id" (you can find the fix for this here Android Studio 1.0 and error "Library projects cannot set applicationId").

By removing application Id in the build.gradle file, you should be good to go.

cpdf will do the job from the command-line. It isn't python, though (afaik):

cpdf -add-text "Line of text" input.pdf -o output .pdf

This will print the IP addresses in the output of ipconfig:

@echo off
set ip_address_string="IPv4 Address"
rem Uncomment the following line when using older versions of Windows without IPv6 support (by removing "rem")
rem set ip_address_string="IP Address"
echo Network Connection Test
for /f "usebackq tokens=2 delims=:" %%f in (`ipconfig ^| findstr /c:%ip_address_string%`) do echo Your IP Address is: %%f

To only print the first IP address, just add goto :eof (or another label to jump to instead of :eof) after the echo, or in a more readable form:

set ip_address_string="IPv4 Address"
rem Uncomment the following line when using older versions of Windows without IPv6 support (by removing "rem")
rem set ip_address_string="IP Address"
for /f "usebackq tokens=2 delims=:" %%f in (`ipconfig ^| findstr /c:%ip_address_string%`) do (
    echo Your IP Address is: %%f
    goto :eof
)

A more configurable way would be to actually parse the output of ipconfig /all a little bit, that way you can even specify the adapter whose IP address you want:

@echo off
setlocal enabledelayedexpansion
::just a sample adapter here:
set "adapter=Ethernet adapter VirtualBox Host-Only Network"
set adapterfound=false
echo Network Connection Test
for /f "usebackq tokens=1-2 delims=:" %%f in (`ipconfig /all`) do (
    set "item=%%f"
    if /i "!item!"=="!adapter!" (
        set adapterfound=true
    ) else if not "!item!"=="!item:IP Address=!" if "!adapterfound!"=="true" (
        echo Your IP Address is: %%g
        set adapterfound=false
    )
)

To verify at server side using PHP. Two most important thing you need to consider.

1. $_POST['g-recaptcha-response']

2.$secretKey = '6LeycSQTAAAAAMM3AeG62pBslQZwBTwCbzeKt06V';

$verifydata = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secretKey.'&response='.$_POST['g-recaptcha-response']);
        $response= json_decode($verifydata);

If you get $verifydata true, You done.

Warning: this is a dangerous method! It abuses the i/o buffers in linux and with specific options of buffering it manages to work on small files. It is an interesting curiosity. But don't use it for a real situation!

Besides the -i option of sed you can use the tee utility.

From man:

tee - read from standard input and write to standard output and files

So, the solution would be:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee | tee index.html

-- here the tee is repeated to make sure that the pipeline is buffered. Then all commands in the pipeline are blocked until they get some input to work on. Each command in the pipeline starts when the upstream commands have written 1 buffer of bytes (the size is defined somewhere) to the input of the command. So the last command tee index.html, which opens the file for writing and therefore empties it, runs after the upstream pipeline has finished and the output is in the buffer within the pipeline.

Most likely the following won't work:

sed s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g index.html | tee index.html

-- it will run both commands of the pipeline at the same time without any blocking. (Without blocking the pipeline should pass the bytes line by line instead of buffer by buffer. Same as when you run cat | sed s/bar/GGG/. Without blocking it's more interactive and usually pipelines of just 2 commands run without buffering and blocking. Longer pipelines are buffered.) The tee index.html will open the file for writing and it will be emptied. However, if you turn the buffering always on, the second version will work too.

CSS has a feature: Conditional Rules. This feature of CSS is applied based on a specific condition. Conditional Rules are:

• @supports
• @media
• @document

Syntax:

@supports ("condition") {

   /* your css style */

}

Example code snippet:

<!DOCTYPE html> 
<html> 
<head> 
    <title>Supports Rule</title> 
    <style>      
        @supports (display: block) {

                background-color: pink; 
                color: white; 
            } 
            section h2 { 
                background-color: pink; 
                color: black; 
            } 
        } 
    </style>

AFAIK, RTSP does not transmit streams at all, it is just an out-of-band control protocol with functions like PLAY and STOP.

Raw UDP or RTP over UDP are transmission protocols for streams just like raw TCP or HTTP over TCP.

To be able to stream a certain program over the given transmission protocol, an encapsulation method has to be defined for your container format. For example TS container can be transmitted over UDP but Matroska can not.

Pretty much everything can be transported through TCP though.

(The fact that which codec do you use also matters indirectly as it restricts the container formats you can use.)

This is to do with JavaScript's + in operator - if a number and a string are "added" up, the number is converted into a string:

0 + 1; //1
'0' + 1; // '01'

To solve this, use the + unary operator, or use parseInt():

+'0' + 1; // 1
parseInt('0', 10) + 1; // 1

The unary + operator converts it into a number (however if it's a decimal it will retain the decimal places), and parseInt() is self-explanatory (converts into number, ignoring decimal places).

The second argument is necessary for parseInt() to use the correct base when leading 0s are placed:

parseInt('010'); // 8 in older browsers, 10 in newer browsers
parseInt('010', 10); // always 10 no matter what

There's also parseFloat() if you need to convert decimals in strings to their numeric value - + can do that too but it behaves slightly differently: that's another story though.

Given its complexibility, I think you should go the urlparse way.

For completeness, here's the pseudo-BNF of the above regex (as a documentation):

; new schemes follow the general syntax
otherurl       = genericurl

; the scheme is in lower case; interpreters should use case-ignore

1. Right-click on your project, select Maven -> Remove Maven Nature.

2. Open you terminal, go to your project folder and do mvn eclipse:clean

3. Right click on your Project and select “Configure -> Convert into Maven Project”

Now you got “Unsupported IClasspathEntry kind=4 Eclipse Scala” disappear.

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

https://wordpress.org/plugins/woocommerce-products-filter/

This one seems to do exactly what you are after

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

Class Names. For test fixture names, I find that "Test" is quite common in the ubiquitous language of many domains. For example, in an engineering domain: StressTest, and in a cosmetics domain: SkinTest. Sorry to disagree with Kent, but using "Test" in my test fixtures (StressTestTest?) is confusing.

"Unit" is also used a lot in domains. E.g. MeasurementUnit. Is a class called MeasurementUnitTest a test of "Measurement" or "MeasurementUnit"?

Therefore I like to use the "Qa" prefix for all my test classes. E.g. QaSkinTest and QaMeasurementUnit. It is never confused with domain objects, and using a prefix rather than a suffix means that all the test fixtures live together visually (useful if you have fakes or other support classes in your test project)

Namespaces. I work in C# and I keep my test classes in the same namespace as the class they are testing. It is more convenient than having separate test namespaces. Of course, the test classes are in a different project.

Test method names. I like to name my methods WhenXXX_ExpectYYY. It makes the precondition clear, and helps with automated documentation (a la TestDox). This is similar to the advice on the Google testing blog, but with more separation of preconditions and expectations. For example:

WhenDivisorIsNonZero_ExpectDivisionResult
WhenDivisorIsZero_ExpectError
WhenInventoryIsBelowOrderQty_ExpectBackOrder
WhenInventoryIsAboveOrderQty_ExpectReducedInventory

This seemed to work for me:

EventHandler<ActionEvent> quitHandler = quitEvent -> {

        System.exit(0);

    };
    // Set the handler on the Start/Resume button
    quit.setOnAction(quitHandler);

For i:= 0 to X do For j := 0 to X do graphic[j][i] := graphic2[X-i][j]

X is the size of the array the graphic is in.

Here's a simple function I wrote to display tabular data without having to input each column name: (Also, be aware: Nested looping)

function display_data($data) {
    $output = '<table>';
    foreach($data as $key => $var) {
        $output .= '<tr>';
        foreach($var as $k => $v) {
            if ($key === 0) {
                $output .= '<td><strong>' . $k . '</strong></td>';
            } else {
                $output .= '<td>' . $v . '</td>';
            }
        }
        $output .= '</tr>';
    }
    $output .= '</table>';
    echo $output;
}

UPDATED FUNCTION BELOW

Hi Jack,

your function design is fine, but this function always misses the first dataset in the array. I tested that.

Your function is so fine, that many people will use it, but they will always miss the first dataset. That is why I wrote this amendment.

The missing dataset results from the condition if key === 0. If key = 0 only the columnheaders are written, but not the data which contains $key 0 too. So there is always missing the first dataset of the array.

You can avoid that by moving the if condition above the second foreach loop like this:

function display_data($data) {
    $output = "<table>";
    foreach($data as $key => $var) {
        //$output .= '<tr>';

and another update that removes redundant code blocks that hurt maintainability of the code.

function display_data($data) {
$output = '<table>';
foreach($data as $key => $var) {
    $output .= '<tr>';
    foreach($var as $k => $v) {
        if ($key === 0) {
            $output .= '<td><strong>' . $k . '</strong></td>';
        } else {
            $output .= '<td>' . $v . '</td>';
        }
    }
    $output .= '</tr>';
}
$output .= '</table>';
echo $output;

}

You can use "is not" for "not equal" or "!=". Please see the example below:

a = 2
if a == 2:
   print("true")
else:
   print("false")

The above code will print "true" as a = 2 assigned before the "if" condition. Now please see the code below for "not equal"

a = 2
if a is not 3:
   print("not equal")
else:
   print("equal")

The above code will print "not equal" as a = 2 as assigned earlier.

Setting

max-width:100%;
white-space:nowrap;

will solve your problem.

As an alternative to the other answers, django-devserver outputs SQL to the console.

Jason Scheirer's answer is correct but could use some more exposition.

First off, to repeat a string an integer number of times, you can use overloaded multiplication:

>>> 'abc' * 7
'abcabcabcabcabcabcabc'

So, to repeat a string until it's at least as long as the length you want, you calculate the appropriate number of repeats and put it on the right-hand side of that multiplication operator:

def repeat_to_at_least_length(s, wanted):
    return s * (wanted//len(s) + 1)

>>> repeat_to_at_least_length('abc', 7)
'abcabcabc'

Then, you can trim it to the exact length you want with an array slice:

def repeat_to_length(s, wanted):
    return (s * (wanted//len(s) + 1))[:wanted]

>>> repeat_to_length('abc', 7)
'abcabca'

Alternatively, as suggested in pillmod's answer that probably nobody scrolls down far enough to notice anymore, you can use divmod to compute the number of full repetitions needed, and the number of extra characters, all at once:

def pillmod_repeat_to_length(s, wanted):
    a, b = divmod(wanted, len(s))
    return s * a + s[:b]

Which is better? Let's benchmark it:

>>> import timeit
>>> timeit.repeat('scheirer_repeat_to_length("abcdefg", 129)', globals=globals())
[0.3964178159367293, 0.32557755894958973, 0.32851039397064596]
>>> timeit.repeat('pillmod_repeat_to_length("abcdefg", 129)', globals=globals())
[0.5276265419088304, 0.46511475392617285, 0.46291469305288047]

So, pillmod's version is something like 40% slower, which is too bad, since personally I think it's much more readable. There are several possible reasons for this, starting with its compiling to about 40% more bytecode instructions.

Note: these examples use the new-ish // operator for truncating integer division. This is often called a Python 3 feature, but according to PEP 238, it was introduced all the way back in Python 2.2. You only have to use it in Python 3 (or in modules that have from __future__ import division) but you can use it regardless.

Thanks to dimo414's answer to a similar question, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

git push public :master

This would delete the remote branch named master as Kent Fredric has pointed out.

To list remote-tracking branches:

git branch -r

To delete a remote-tracking branch:

git branch -rd public/master

@Transactional =javax.transaction.Transactional. Put it just beside @Repository.

its possible if you already have a python installed (pip) you could do a upgrade on mac by

brew upgrade python

I had the same problem when i was trying to build my own directive, and i fixed with this add

ctrl.$validate();

where ctrl is my ngModelController

this is my view

<input type="password" match="signupCtrl.registrationData.password" name="confirmPassword" class="form-control" placeholder="Confirm Password" data-ng-model="signupCtrl.registrationData.confirmPassword" required>
        <span ng-messages="registerForm.confirmPassword.$error">
            <span ng-message="match">The Password must match</span>
        </span>

this is my directive

(function () {
    'use strict';
    angular.module('matchDirective', [
        // Angular modules
        // Custom modules
        // 3rd Party Modules
    ]);
})(); 
(function () {
    'use strict';
    angular
        .module('matchDirective')
        .directive('match', match);
    match.$inject = ['$window'];

    function match($window) {
        // Usage:
        //     <element match="source"></element>
        // Creates:
        //
        var directive = {
            link: link,
            restrict: 'A',
            require: 'ngModel',
        };
        return directive;

        function link(scope, element, attrs, ctrl) {
            scope.$watch(attrs['match'], function (newVal, oldVal) {
                ctrl.$validators.match = function (modelValue, viewValue) {
                    if (newVal == modelValue) {
                        return true;
                    } else {
                        return false;
                    }
                }
                ctrl.$validate();
            });
        }
    }
})();

Six years on, this is still at the top for some searches. Things have changed a lot since then. Now the defacto standard is more or less to use Volley and the NetworkImageView which takes care of the heavy lifting for you.

Assuming that you already have your Apaters, Loaders and ListFragments setup properly, this official google tutorial explains how to use NetworkImageView to load the images. Images are automatically loaded in a background thread and the view updated on the UI thread. It even supports caching.

yEnc might work for you:

http://en.wikipedia.org/wiki/Yenc

"yEnc is a binary-to-text encoding scheme for transferring binary files in [text]. It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit Extended ASCII encoding method. yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, compared to 33%–40% overhead for 6-bit encoding methods like uuencode and Base64. ... By 2003 yEnc became the de facto standard encoding system for binary files on Usenet."

However, yEnc is an 8-bit encoding, so storing it in a JSON string has the same problems as storing the original binary data — doing it the naïve way means about a 100% expansion, which is worse than base64.

You can use the % operator to find the remainder of a division, and compare the result with 0.

Example:

if (number % divisor == 0)
{
    //code for perfect divisor
}
else
{
    //the number doesn't divide perfectly by divisor
}

What about using constructor?

class myClass {

   $myNumber = NULL;

   public function __construct() {
      global myNumber;

      $this->myNumber = &myNumber; 
   }

   public function foo() {
      echo $this->myNumber;
   }

}

Or much better this way (passing the global variable as parameter when inicializin the object - read only)

class myClass {

   $myNumber = NULL;

   public function __construct($myNumber) {
      $this->myNumber = $myNumber; 
   }

   public function foo() {
      echo $this->myNumber;
   }

}
$instance = new myClass($myNumber);

If you have Iterable convert to stream and find last element

 Iterator<String> sourceIterator = Arrays.asList("one", "two", "three").iterator();

 Iterable<String> iterable = () -> sourceIterator;


 String last = StreamSupport.stream(iterable.spliterator(), false).reduce((first, second) -> second).orElse(null);
