Use the in_array() function.

$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');

if (in_array('kitchen', $array)) {
    echo 'this array contains kitchen';
}

Firstly, let's use some semantic HTML.

<nav class="navigation-bar">
    <img class="logo" src="logo.png">
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">Projects</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Get in Touch</a></li>
    </ul>
</nav>

In fact, you can even get away with the more minimalist:

<nav class="navigation-bar">
    <img class="logo" src="logo.png">
    <a href="#">Home</a>
    <a href="#">Projects</a>
    <a href="#">About</a>
    <a href="#">Services</a>
    <a href="#">Get in Touch</a>
</nav>

Then add some CSS:

.navigation-bar {
    width: 100%;  /* i'm assuming full width */
    height: 80px; /* change it to desired width */
    background-color: red; /* change to desired color */
}
.logo {
    display: inline-block;
    vertical-align: top;
    width: 50px;
    height: 50px;
    margin-right: 20px;
    margin-top: 15px;    /* if you want it vertically middle of the navbar. */
}
.navigation-bar > a {
    display: inline-block;
    vertical-align: top;
    margin-right: 20px;
    height: 80px;        /* if you want it to take the full height of the bar */
    line-height: 80px;    /* if you want it vertically middle of the navbar */
}

Obviously, the actual margins, heights and line-heights etc. depend on your design.

Other options are to use tables or floats for layout, but these are generally frowned upon.

Last but not least, I hope you get cured of div-itis.

You are looking to use dirname. If you only want that one directory, you can use os.path.basename,

When put all together it looks like this:

os.path.basename(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))

That should get you "other_sub_dir"

The following is not the ideal approach, but I originally proposed,using os.path.split, and simply get the last item. which would look like this:

os.path.split(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))[-1]

You can do this for webkit:

#text2::-webkit-input-placeholder::before {
    color:#666;
    content:"Line 1\A Line 2\A Line 3\A";
}

http://jsfiddle.net/Z3tFG/1/

For transitions you can use the following to detect the end of a transition via jQuery:

$("#someSelector").bind("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){ ... });

Mozilla has an excellent reference:

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions#Detecting_the_start_and_completion_of_a_transition

For animations it's very similar:

$("#someSelector").bind("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd", function(){ ... });

Note that you can pass all of the browser prefixed event strings into the bind() method simultaneously to support the event firing on all browsers that support it.

Update:

Per the comment left by Duck: you use jQuery's .one() method to ensure the handler only fires once. For example:

$("#someSelector").one("transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd", function(){ ... });

$("#someSelector").one("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd", function(){ ... });

Update 2:

jQuery bind() method has been deprecated, and on() method is preferred as of jQuery 1.7. bind()

You can also use off() method on the callback function to ensure it will be fired only once. Here is an example which is equivalent to using one() method:

$("#someSelector")
.on("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd",
 function(e){
    // do something here
    $(this).off(e);
 });

References:

• .off()

• .one()

With Microsoft SQL Server:

Use Syntax for CONVERT:

CONVERT ( data_type [ ( length ) ] , expression [ , style ] )

Example:

SELECT CONVERT(varchar,d.dateValue,1-9)

For the style you can find more info here: MSDN - Cast and Convert (Transact-SQL).

This can be done elegantly with Ray, a system that allows you to easily parallelize and distribute your Python code.

To parallelize your example, you'd need to define your functions with the @ray.remote decorator, and then invoke them with .remote.

import ray

ray.init()

dir1 = 'C:\\folder1'
dir2 = 'C:\\folder2'
filename = 'test.txt'
addFiles = [25, 5, 15, 35, 45, 25, 5, 15, 35, 45]

# Define the functions. 
# You need to pass every global variable used by the function as an argument.
# This is needed because each remote function runs in a different process,
# and thus it does not have access to the global variables defined in 
# the current process.
@ray.remote
def func1(filename, addFiles, dir):
    # func1() code here...

@ray.remote
def func2(filename, addFiles, dir):
    # func2() code here...

# Start two tasks in the background and wait for them to finish.
ray.get([func1.remote(filename, addFiles, dir1), func2.remote(filename, addFiles, dir2)]) 

If you pass the same argument to both functions and the argument is large, a more efficient way to do this is using ray.put(). This avoids the large argument to be serialized twice and to create two memory copies of it:

largeData_id = ray.put(largeData)

ray.get([func1(largeData_id), func2(largeData_id)])

Important - If func1() and func2() return results, you need to rewrite the code as follows:

ret_id1 = func1.remote(filename, addFiles, dir1)
ret_id2 = func2.remote(filename, addFiles, dir2)
ret1, ret2 = ray.get([ret_id1, ret_id2])

There are a number of advantages of using Ray over the multiprocessing module. In particular, the same code will run on a single machine as well as on a cluster of machines. For more advantages of Ray see this related post.

Use Google Sheets instead of Excel - this feature is built in, so you can use regex right from the find and replace dialog.

To answer your question:

1. Copy the data from Excel and paste into Google Sheets
2. Use the find and replace dialog with regex
3. Copy the data from Google Sheets and paste back into Excel

The -e and -t parameter does not work together. i tried some expressions and the result was the following code snippet :

QMESSAGE="SHOULD I DO YES OR NO"
YMESSAGE="I DO"
NMESSAGE="I DO NOT"
FMESSAGE="PLEASE ENTER Y or N"
COUNTDOWN=2
DEFAULTVALUE=n
#----------------------------------------------------------------#
function REQUEST ()

    INPUT=${INPUT:-$DEFAULTVALUE}
    if  [ "$INPUT" = "y" -o "$INPUT" = "Y" ] ;then
        echo -e "\n$YMESSAGE\n"
        #COMMANDEXECUTION
    elif    [ "$INPUT" = "n" -o "$INPUT" = "N" ] ;then
        echo -e "\n$NMESSAGE\n"
        #COMMANDEXECUTION
    else
        echo -e "\n$FMESSAGE\n"
    REQUEST
    fi
}

This is a solution that means that as you add new stored procedures to the schema, users can execute them without having to call grant execute on the new stored procedure:

IF  EXISTS (SELECT * FROM sys.database_principals WHERE name = N'asp_net')
DROP USER asp_net
GO

IF  EXISTS (SELECT * FROM sys.database_principals 
WHERE name = N'db_execproc' AND type = 'R')
DROP ROLE [db_execproc]
GO

--Create a database role....
CREATE ROLE [db_execproc] AUTHORIZATION [dbo]
GO

--...with EXECUTE permission at the schema level...
GRANT EXECUTE ON SCHEMA::dbo TO db_execproc;
GO

--http://www.patrickkeisler.com/2012/10/grant-execute-permission-on-all-stored.html
--Any stored procedures that are created in the dbo schema can be 
--executed by users who are members of the db_execproc database role

--...add a user e.g. for the NETWORK SERVICE login that asp.net uses
CREATE USER asp_net 
FOR LOGIN [NT AUTHORITY\NETWORK SERVICE] 
WITH DEFAULT_SCHEMA=[dbo]
GO

--...and add them to the roles you need
EXEC sp_addrolemember N'db_execproc', 'asp_net';
EXEC sp_addrolemember N'db_datareader', 'asp_net';
EXEC sp_addrolemember N'db_datawriter', 'asp_net';
GO

@Jon's answer is great and will get you where you need to go. So why is your code printing out what it is. The answer: You're not writing out the contents of your list, but the String representation of your list itself, by an implicit call to Lists.verbList.ToString(). Object.ToString() defines the default behavior you're seeing here.

I think the *break*s are there for a purpose. It is to keep the 'ideology' of programming alive. If we are to just 'program' our code without logical coherence perhaps it would be readable to you now, but try tomorrow. Try explaining it to your boss. Try running it on Windows 3030.

Bleah, the idea is very simple:

 case 2:

 case 3:

PUT ing

PUT /binders/{id}/docs Create or update, and relate a single document to a binder

e.g.:

PUT /binders/1/docs HTTP/1.1
{
  "docNumber" : 1

PATCH ing

PATCH /docs Create docs if they do not exist and relate them to binders

e.g.:

PATCH /docs HTTP/1.1
[
    { "op" : "add", "path" : "/binder/1/docs", "value" : { "doc_number" : 1 } },
    { "op" : "add", "path" : "/binder/8/docs", "value" : { "doc_number" : 8 } },

I have tried this pure component:

const RawHTML = ({children, className = ""}) => 
<div className={className}
  dangerouslySetInnerHTML={{ __html: children.replace(/\n/g, '<br />')}} />

Features

• Takes classNameprop (easier to style it)
• Replaces \n to <br /> (you often want to do that)
• Place content as children when using the component like:
• <RawHTML>{myHTML}</RawHTML>

I have placed the component in a Gist at Github: RawHTML: ReactJS pure component to render HTML

MYSQL 8 does, in a way:

MYSQL 8 supports JSON tables, so you could load your results into a JSON variable and select from that variable using the JSON_TABLE() command.

Iam confused a lot from morning whether it should be less than or greater than`

this can accept value less than "99999"

I think you answered it yourself... But it's valid when it's less than. Thus the following is incorrect:

}elseif($("#seats").val() < 99999){
  alert("Not a valid Number");
}else{

You are saying if it's less than 99999, then it's not valid. You want to do the opposite:

}elseif($("#seats").val() >= 99999){
  alert("Not a valid Number");
}else{

Also, since you have $("#seats") twice, jQuery has to search the DOM twice. You should really be storing the value, or at least the DOM element in a variable. And some more of your code doesn't make much sense, so I'm going to make some assumptions and put it all together:

var seats = $("#seats").val();

var error = null;

if (seats == "") {
    error = "Number is required";
} else {
    var seatsNum = parseInt(seats);
    
    if (isNaN(seatsNum)) {
        error = "Not a valid number";
    } else if (seatsNum >= 99999) {
        error = "Number must be less than 99999";
    }
}

if (error != null) {
    alert(error);
} else {
    alert("Valid number");
}

// If you really need setflag:
var setflag = error != null;

The console.log should be wrapped in a function , the "default" function for every class is its constructor so it should be declared there.

import { Component } from '@angular/core';
console.log("Hello1");

 @Component({
  selector: 'hello-console',
})
    export class App {
     s: string = "Hello2";
    constructor(){
     console.log(s); 
    }

}

With regards to @CrazyJugglerDrummer second method it would be:

elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";

The for attribute is called htmlFor for consistency with the DOM property API. If you're using the development build of React, you should have seen a warning in your console about this.

proposed solution edit works if you replace the row

Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

with

Set rDst = ThisWorkbook.Sheets("SomeSheet").Range("YourRange").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

In Oracle, you could use rownum to limit the number of rows returned. I am guessing similar construct exists in other SQLs as well. So, for the example you gave, you could limit the number of rows returned to 500001 and apply a count(*) then:

SELECT (case when cnt > 500000 then 500000 else cnt end) myCnt
FROM (SELECT count(*) cnt FROM table WHERE rownum<=500001)

So long as Excel can open the file, the functionality to change the format of the opened file is built in.

To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).

To do it using VBA, the code would look like this:

Sub Open_HTML_Save_XLSX()

    Workbooks.Open Filename:="C:\Temp\Example.html"
    ActiveWorkbook.SaveAs Filename:= _
        "C:\Temp\Example.xlsx", FileFormat:= _
        xlOpenXMLWorkbook

End Sub

Try:

Bitmap yourBitmap;
Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

Yes, it is absolutely no problem. You could even have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

In fact, i have such a setup myself.

Like the other answer says, put the & after the *.

This brings up an interesting point that can be confusing sometimes: types should be read from right to left. For example, this is (starting from the rightmost *) a pointer to a constant pointer to an int.

int * const *x;

What you wrote would therefore be a pointer to a reference, which is not possible.

If you want to just "set" the actual filename, without incurring the overhead of loading and re-saving the file (!!), or resorting to using a charfield (!!!), you might want to try something like this --

model_instance.myfile = model_instance.myfile.field.attr_class(model_instance, model_instance.myfile.field, 'my-filename.jpg')

This will light up your model_instance.myfile.url and all the rest of them just as if you'd actually uploaded the file.

Like @t-stone says, what we really want, is to be able to set instance.myfile.path = 'my-filename.jpg', but Django doesn't currently support that.

A little bit late but I got the same error and I realized that it was because I copied some code from a PDF. Check the difference between these two: - - The first one is from hitting the minus sign on keyboard and the second is from a latex generated PDF.

All comments brought up so far are valid. Where possible you need to specify what exactly exception you want to ignore. Where possible you need to analyze what caused exception, and only ignore what you meant to ignore, and not the rest. If exception causes application to "crash spectacularly", then be it, because it's much more important to know the unexpected happened when it happened, than concealing that the problem ever occurred.

With all that said, do not take any programming practice as a paramount. This is stupid. There always is the time and place to do ignore-all-exceptions block.

Another example of idiotic paramount is usage of goto operator. When I was in school, our professor taught us goto operator just to mention that thou shalt not use it, EVER. Don't believe people telling you that xyz should never be used and there cannot be a scenario when it is useful. There always is.

String arr = "[1,2]";
String[] items = arr.replaceAll("\\[", "").replaceAll("\\]", "").replaceAll("\\s", "").split(",");

int[] results = new int[items.length];

for (int i = 0; i < items.length; i++) {
    try {
        results[i] = Integer.parseInt(items[i]);
    } catch (NumberFormatException nfe) {
        //NOTE: write something here if you need to recover from formatting errors
    };
}

You can try this code :

int columnIndex = dataGridView.CurrentCell.ColumnIndex;
int rowIndex = dataGridView.CurrentCell.RowIndex;

Not certain what the HTML looks like (that would help with answers). If it's

<div class="testimonials content">stuff</div>

then simply remove the space in your css. A la...

.testimonials.content { css here }

UPDATE:

Okay, after seeing HTML see if this works...

.testimonials .wrapper .content { css here }

or just

.testimonials .wrapper { css here }

or

.desc-container .wrapper { css here }

all 3 should work.

To pull a remote branch locally, I do the following:

git checkout -b branchname // creates a local branch with the same name and checks out on it

git pull origin branchname // pulls the remote one onto your local one

The only time I did this and it didn't work, I deleted the repo, cloned it again and repeated the above 2 steps; it worked.

The following macro is not quite as compact as a single-use ostringstream or boost::lexical_cast.

But if you need conversion-to-string repeatedly in your code, this macro is more elegant in use than directly handling stringstreams or explicit casting every time.

It is also very versatile, as it converts everything supported by operator<<(), even in combination.

Definition:

#include <sstream>

#define SSTR( x ) dynamic_cast< std::ostringstream & >( \
            ( std::ostringstream() << std::dec << x ) ).str()

Explanation:

The std::dec is a side-effect-free way to make the anonymous ostringstream into a generic ostream so operator<<() function lookup works correctly for all types. (You get into trouble otherwise if the first argument is a pointer type.)

The dynamic_cast returns the type back to ostringstream so you can call str() on it.

Use:

#include <string>

int main()
{
    int i = 42;
    std::string s1 = SSTR( i );

    int x = 23;
    std::string s2 = SSTR( "i: " << i << ", x: " << x );
    return 0;
}

Just as an alternative approach to you can do:

WITH inner_table AS
(SELECT A.identifier
    , A.name
    , TO_NUMBER(DECODE( A.month_no
      , 1, 200803 
      , 2, 200804 
      , 3, 200805 
      , 4, 200806 
      , 5, 200807 
      , 6, 200808 
      , 7, 200809 
      , 8, 200810 
      , 9, 200811 
      , 10, 200812 
      , 11, 200701 
      , 12, 200702
      , NULL)) as MONTH_NO
    , TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
  FROM table_a A
    , table_b B
  WHERE A.identifier = B.identifier)

    SELECT * FROM inner_table 
    WHERE MONTH_NO > UPD_DATE

Also you can create a permanent view for your queue and select from view.

CREATE OR REPLACE VIEW_1 AS (SELECT ...);
SELECT * FROM VIEW_1;

You should assign an array of char pointers, and then, for each pointer assign enough memory for the string:

char **orderedIds;

orderedIds = malloc(variableNumberOfElements * sizeof(char*));
for (int i = 0; i < variableNumberOfElements; i++)
    orderedIds[i] = malloc((ID_LEN+1) * sizeof(char)); // yeah, I know sizeof(char) is 1, but to make it clear...

Seems like a good way to me. Although you perform many mallocs, you clearly assign memory for a specific string, and you can free one block of memory without freeing the whole "string array"

How about

Select I.Fee
From Item I
WHERE  (days(GETDATE()) - days(I.DateCreated) < 365)

How about using Xcode built-in code snippet library?

Update for Swift:

Many up votes inspired me to update this answer.

The build-in Xcode code snippet library has dispatch_after for only objective-c language. People can also create their own Custom Code Snippet for Swift.

Write this in Xcode.

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(<#delayInSeconds#> * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), {
        <#code to be executed after a specified delay#>
    })

Drag this code and drop it in the code snippet library area.

Bottom of the code snippet list, there will be a new entity named My Code Snippet. Edit this for a title. For suggestion as you type in the Xcode fill in the Completion Shortcut.

For more info see CreatingaCustomCodeSnippet.

Update Swift 3

Drag this code and drop it in the code snippet library area.

DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(<#delayInSeconds#>)) {
    <#code to be executed after a specified delay#>
}

The title of your question is:

How to join a slice of strings into a single string?

but in fact, reg is not a slice, but a length-three array. [...]string is just syntactic sugar for (in this case) [3]string.

To get an actual slice, you should write:

reg := []string {"a","b","c"}

(Try it out: https://play.golang.org/p/vqU5VtDilJ.)

Incidentally, if you ever really do need to join an array of strings into a single string, you can get a slice from the array by adding [:], like so:

fmt.Println(strings.Join(reg[:], ","))

(Try it out: https://play.golang.org/p/zy8KyC8OTuJ.)

In vim You can type :%!xxd to turn it into a hexeditor. :%!xxd -r to go back to normal mode. xxd is shipped in a vim installation.

See here for some remarks about editing binary files with vim (boils down to :set binary to avoid trouble, use only the "R" or "r" command to change text, don't delete characters).

If You are an Emacs fan, see here for a guide on how to edit a binary file with Emacs.

Update: PointedEars mentions that the correct stand in for   in all css situations would be
'\a0 ' implying that the space is a terminator to the hex string and is absorbed by the escaped sequence. He further pointed out this authoritative description which sounds like a good solution to the problem I described and fixed below.

What you need to do is use the escaped unicode. Despite what you've been told \00a0 is not a perfect stand-in for   within CSS; so try:

content:'>\a0 ';          /* or */
content:'>\0000a0';       /* because you'll find: */
content:'No\a0 Break';    /* and */
content:'No\0000a0Break'; /* becomes No Break as opposed to below */

Specifically using \0000a0 as  . If you try, as suggested by mathieu and millikin:

content:'No\00a0Break'   /* becomes No਋reak */

It takes the B into the hex escaped characters. The same occurs with 0-9a-fA-F.

1.You can make overload functions.

SomeF(strin s){}   
SomeF(string s, string s2){}    
SomeF(string s1, string s2, string s3){}   

More info: http://csharpindepth.com/Articles/General/Overloading.aspx

2.or you may create one function with params

SomeF( params string[] paramArray){}
SomeF("aa","bb", "cc", "dd", "ff"); // pass as many as you like

I really wanted to comment, not answer. But just to be precise, OSX is not based on BSD, it is an evolution of NeXTStep. The NeXTStep OS utilizes the Mach kernel developed by CMU. It was originally designed as a MicroKernel, but due to performance constraints, they eventually decided they needed to include the Unix portion of the API into the kernel itself and so a BSD-compatible "server" (originally intended to process requests for BSD-compatible kernel messages) was moved into the kernel, making it a Monolithic kernel. It may be BSD compatible in the programming API, but it is NOT BSD.

The rest of the OS involved ObjectiveC (under arrangements between Stepstone and Richard Stallman of GNU/GCC) with a GUI based on a technology called "Display Postscript" ... sort of like an X Server, but with postscript commands. OS X changed Display Postscript to Display PDF, and increased the general hardware requirements 1000 fold (NeXT could run in 8-16MB, now you need GB).

Due to the close marriage of GCC and Objective C and NeXT, your best bet at running XCode natively under Linux would be to do a port (if you can get ahold of the source - good luck) utilizing the GNUStep libraries. Originally designed for NextStep and then OpenStep compatibility, I've heard they are now more-or-less Cocoa compatible, but I've not played with any of it in almost 2 decades. Of course that only gets you as far as ObjC, not Swift, and I don't know if Apple is going to OpenSource it.

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

If you had a IDE open with the same code, try doing a ctrl+z on each individual file that you have made changes to. It helped me recover my uncommited changes after doing git reset --hard.

Use the make_response method to get a response with your data. Then set the mimetype attribute. Finally return this response:

@app.route('/ajax_ddl')
def ajax_ddl():
    xml = 'foo'
    resp = app.make_response(xml)
    resp.mimetype = "text/xml"
    return resp

If you use Response directly, you lose the chance to customize the responses by setting app.response_class. The make_response method uses the app.responses_class to make the response object. In this you can create your own class, add make your application uses it globally:

class MyResponse(app.response_class):
    def __init__(self, *args, **kwargs):
        super(MyResponse, self).__init__(*args, **kwargs)
        self.set_cookie("last-visit", time.ctime())

app.response_class = MyResponse  

As also noted in the docs here.
Go to Python X.X/Lib and add these lines to the site.py there,

import sys
sys.path.append("yourpathstring")

This changes your sys.path so that on every load, it will have that value in it..

As stated here about site.py,

This module is automatically imported during initialization. Importing this module will append site-specific paths to the module search path and add a few builtins.

For other possible methods of adding some path to sys.path see these docs

format_train_y=[]
for n in train_y:
    format_train_y.append(n[0])

I followed the steps in killthrush's answer and to my surprise it did not work. Logging in as sa I could see my Windows domain user and had made them a sysadmin, but when I tried logging in with Windows auth I couldn't see my login under logins, couldn't create databases, etc. Then it hit me. That login was probably tied to another domain account with the same name (with some sort of internal/hidden ID that wasn't right). I had left this organization a while back and then came back months later. Instead of re-activating my old account (which they might have deleted) they created a new account with the same domain\username and a new internal ID. Using sa I deleted my old login, re-added it with the same name and added sysadmin. I logged back in with Windows Auth and everything looks as it should. I can now see my logins (and others) and can do whatever I need to do as a sysadmin using my Windows auth login.

Could you try this one:

create or replace

If getting this error trying to build .Net Core 2.0 app on VSTS then ensure your build definition is using the Hosted VS2017 Agent queue.

kieron's answer contains w3schools ref. to which nobody rely , bobince's answer gives link , which actually tells native implementation of IE ,

so here is the original documentation quoted to rightly understand what readystate represents :

The XMLHttpRequest object can be in several states. The readyState attribute must return the current state, which must be one of the following values:

UNSENT (numeric value 0)
The object has been constructed.

OPENED (numeric value 1)
The open() method has been successfully invoked. During this state request headers can be set using setRequestHeader() and the request can be made using the send() method.

HEADERS_RECEIVED (numeric value 2)
All redirects (if any) have been followed and all HTTP headers of the final response have been received. Several response members of the object are now available.

LOADING (numeric value 3)
The response entity body is being received.

DONE (numeric value 4)
The data transfer has been completed or something went wrong during the transfer (e.g. infinite redirects).

Please Read here : W3C Explaination Of ReadyState

Change your last statement to this:

EXEC('SELECT * FROM ' + @tablename)

This is how I do mine in a stored procedure. The first block will declare the variable, and set the table name based on the current year and month name, in this case TEST_2012OCTOBER. I then check if it exists in the database already, and remove if it does. Then the next block will use a SELECT INTO statement to create the table and populate it with records from another table with parameters.

--DECLARE TABLE NAME VARIABLE DYNAMICALLY
DECLARE @table_name varchar(max)
SET @table_name =
    (SELECT 'TEST_'
            + DATENAME(YEAR,GETDATE())
            + UPPER(DATENAME(MONTH,GETDATE())) )

--DROP THE TABLE IF IT ALREADY EXISTS
IF EXISTS(SELECT name
          FROM sysobjects
          WHERE name = @table_name AND xtype = 'U')

BEGIN
    EXEC('drop table ' +  @table_name)
END

--CREATES TABLE FROM DYNAMIC VARIABLE AND INSERTS ROWS FROM ANOTHER TABLE
EXEC('SELECT * INTO ' + @table_name + ' FROM dbo.MASTER WHERE STATUS_CD = ''A''')

Unfortunately, this is not a trivial thing to solve for the general case. The easiest thing would be to add a css-style property "float: right;" to your 200px div, however, this would also cause your "main"-div to actually be full width and any text in there would float around the edge of the 200px-div, which often looks weird, depending on the content (pretty much in all cases except if it's a floating image).

EDIT: As suggested by Dom, the wrapping problem could of course be solved with a margin. Silly me.

You don't have write permissions into the /Library/Ruby/Gems/1.8 directory.

means exactly that, you don't have permission to write there.

That is the version of Ruby installed by Apple, for their own use. While it's OK to make minor modifications to that if you know what you're doing, because you are not sure about the permissions problem, I'd say it's not a good idea to continue along that track.

Instead, I'll strongly suggest you look into using either rbenv or RVM to manage a separate Ruby, installed into a sandbox in your home directory, that you can modify/fold/spindle/change without worrying about messing up the system Ruby.

Between the two, I use rbenv, though I used RVM a lot in the past. rbenv takes a more "hands-off" approach to managing your Ruby installation. RVM has a lot of features and is very powerful, but, as a result is more intrusive. In either case, READ the installation documentation for them a couple times before starting to install whichever you pick.

I tried doing all the above and no luck. I downloaded the latest .net core 2.0 package and ran the commands again and it worked.

I don't see any reason why it would be a bad practice PROVIDED that you want to complete STOP processing at that point.

For those looking for a dynamic solution to embed Matplotlib in PyQt5 (even plot data using drag and drop). In PyQt5 you need to use super on the main window class to accept the drops. The dropevent function can be used to get the filename and rest is simple:

def dropEvent(self,e):
        """
        This function will enable the drop file directly on to the 
        main window. The file location will be stored in the self.filename
        """
        if e.mimeData().hasUrls:
            e.setDropAction(QtCore.Qt.CopyAction)
            e.accept()
            for url in e.mimeData().urls():
                if op_sys == 'Darwin':
                    fname = str(NSURL.URLWithString_(str(url.toString())).filePathURL().path())
                else:
                    fname = str(url.toLocalFile())
            self.filename = fname
            print("GOT ADDRESS:",self.filename)
            self.readData()
        else:
            e.ignore() # just like above functions  

For starters the reference complete code gives this output:

You can also collect with an appropriate summing collector like Collectors#summingInt(ToIntFunction)

Returns a Collector that produces the sum of a integer-valued function applied to the input elements. If no elements are present, the result is 0.

For example

Stream<Obj> filtered = list.stream().filter(o -> o.field > 10);
int sum = filtered.collect(Collectors.summingInt(o -> o.field));

Have you tried redirecting all three I/O streams:

nohup ./yourprogram > foo.out 2> foo.err < /dev/null &

Use -a (for and) and -o (for or) operations.

tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

Update

Actually you could still use && and || with the -eq operation. So your script would be like this:

my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] ||  [ $my_error_flag_o -eq 2 ] || ([ $my_error_flag -eq 1 ] && [ $my_error_flag_o -eq 2 ]); then
      echo "$my_error_flag"
else
    echo "no flag"
fi

Although in your case you can discard the last two expressions and just stick with one or operation like this:

my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] ||  [ $my_error_flag_o -eq 2 ]; then
      echo "$my_error_flag"
else
    echo "no flag"
fi

Based on ejunker's answer, this is the solution working for me, not on a single server but on a cloud enviroment

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{ENV:HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

None of these solutions worked for me. The only workaround I could find was, adding all the min-width sizes together and applying that to the entire table. This obviously only works if you know all the column sizes in advanced, which I do. My tables look something like this:

var columns = [
  {label: 'Column 1', width: 80 /* plus other column config */},
  {label: 'Column 2', minWidth: 110 /* plus other column config */},
  {label: 'Column 3' /* plus other column config */},
];

const minimumTableWidth = columns.reduce((sum, column) => {
  return sum + (column.width || column.minWidth || 0);
}, 0);

tableElement.style.minWidth = minimumTableWidth + 'px';

This is an example and not recommended code. Fit the idea to your requirements. For example, the above is javascript and won't work if the user has JS disabled, etc.

If working with data, many times pandas is the simple key

This particular code will put the raw into one column, then normalize by column per row. (But we can put it into a row and do it by row per column, too! Just have to change the axis values where 0 is for row and 1 is for column.)

import pandas as pd


raw = [0.07, 0.14, 0.07]  

raw_df = pd.DataFrame(raw)
normed_df = raw_df.div(raw_df.sum(axis=0), axis=1)
normed_df

where normed_df will display like:

    0
0   0.25
1   0.50
2   0.25

and then can keep playing with the data, too!

Let us assume the database character set is UTF-8, which is the recommended setting in recent versions of Oracle. In this case, some characters take more than 1 byte to store in the database.

If you define the field as VARCHAR2(11 BYTE), Oracle can use up to 11 bytes for storage, but you may not actually be able to store 11 characters in the field, because some of them take more than one byte to store, e.g. non-English characters.

By defining the field as VARCHAR2(11 CHAR) you tell Oracle it can use enough space to store 11 characters, no matter how many bytes it takes to store each one. A single character may require up to 4 bytes.

I think this would be best explained by the following picture:

To initialize the above, one would type:

import matplotlib.pyplot as plt
fig = plt.figure()
fig.add_subplot(221)   #top left
fig.add_subplot(222)   #top right
fig.add_subplot(223)   #bottom left
fig.add_subplot(224)   #bottom right 
plt.show()

Make the script executable by the user "Kev" and then remove the try it running through the command sh kev@server1 /test/foo.sh

I got this error recently by introducing an old plugin to wordpress. It loaded an older version of jquery, which happened to be placed before the jquery mouse file. There was no jquery widget file loaded with the second version, which caused the error.

No error for using the extra jquery library -- that's a problem especially if a silent fail might have happened, causing a not so silent fail later on.

A potential way around it for wordpress might be to be explicit about the dependencies that way the jquery mouse would follow the widget which would follow the correct core leaving the other jquery to be loaded afterwards. Still might cause a production error later if you don't catch that and change the default function for jquery for the second version in all the files associated with it.

All you need to do is make an array of fields and then set it to the class you want like shown below.

Field fld[] = (class name).class.getDeclaredFields();   
for(Field x : fld)
{System.out.println(x);}

For example if you did

Field fld[] = Integer.class.getDeclaredFields();
          for(Field x : fld)
          {System.out.println(x);}

you would get

public static final int java.lang.Integer.MIN_VALUE
public static final int java.lang.Integer.MAX_VALUE
public static final java.lang.Class java.lang.Integer.TYPE
static final char[] java.lang.Integer.digits
static final char[] java.lang.Integer.DigitTens
static final char[] java.lang.Integer.DigitOnes
static final int[] java.lang.Integer.sizeTable
private static java.lang.String java.lang.Integer.integerCacheHighPropValue
private final int java.lang.Integer.value
public static final int java.lang.Integer.SIZE
private static final long java.lang.Integer.serialVersionUID

You can try Wolfram Alpha as in this example based on your input:

http://www.wolframalpha.com/input/?i=((A%20OR%20B)%20AND%20(NOT%20B%20AND%20C)%20OR%20C)&t=crmtb01&f=rc

If you need to download a huge file from the server's file system, then ByteArrayResource can take all Java heap space. In that case, you can use FileSystemResource

string id;
foreach (GridViewRow rows in grd.Rows)
{
   TextBox lblStrucID = (TextBox)rows.FindControl("grdtext");
   id=lblStrucID.Text
}

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

Probably the only valid reason for using

set enable_seqscan=false

is when you're writing queries and want to quickly see what the query plan would actually be were there large amounts of data in the table(s). Or of course if you need to quickly confirm that your query is not using an index simply because the dataset is too small.

What about ipdb.set_trace() ? In your code :

import ipdb; ipdb.set_trace()

update: now in Python 3.7, we can write breakpoint(). It works the same, but it also obeys to the PYTHONBREAKPOINT environment variable. This feature comes from this PEP.

This allows for full inspection of your code, and you have access to commands such as c (continue), n (execute next line), s (step into the method at point) and so on.

See the ipdb repo and a list of commands. IPython is now called (edit: part of) Jupyter.

ps: note that an ipdb command takes precedence over python code. So in order to write list(foo) you'd need print(list(foo)), or !list(foo) .

Also, if you like the ipython prompt (its emacs and vim modes, history, completions,…) it's easy to get the same for your project since it's based on the python prompt toolkit.

Since pandas 0.22 update, comparison options are available like:

• gt (greater than)
• lt (lesser than)
• eq (equals to)
• ne (not equals to)
• ge (greater than or equals to)

and many more. These functions return boolean array. Let's see how we can use them:

# sample data
df = pd.DataFrame({'col1': [0, 1, 2,3,4,5], 'col2': [10, 11, 12,13,14,15]})

# get values from col1 greater than or equals to 1
df.loc[df['col1'].ge(1),'col1']

1    1
2    2
3    3
4    4
5    5

# where co11 values is better 0 and 2
df.loc[df['col1'].between(0,2)]

 col1 col2
0   0   10
1   1   11
2   2   12

# where col1 > 1
df.loc[df['col1'].gt(1)]

 col1 col2
2   2   12
3   3   13
4   4   14
5   5   15

It will start as soon as the page loads. You can keep it under some events like button click

$("#btn").click(function() { 
var val= $('input[type="radio"]:checked').val();
});

It appears there can by time drift if you're using Docker Machine, as this response suggests: https://stackoverflow.com/a/26454059/105562 , due to VirtualBox.

Quick and easy fix is to just restart your VM:

docker-machine restart default

You can transform logical implication A => B to NOT A or B. This is one of the most basic laws of logic. In your case it is something like this:

SELECT *
FROM logs 
WHERE pw='correct' AND (id>=800 OR success=1)  
AND YEAR(timestamp)=2011

I also transformed NOT id<800 to id>=800, which is also pretty basic.

i have same issue and resolved by

 data: "Id1=" + id1 + "&Id2=" + id2

To complement the existing helpful answers:

Using Bash's own regex-matching operator, =~, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:

set -- '12-34-5678' # set $1 to sample value

kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match

Note, however, that the caveat re using flavor-specific regex constructs such as \d equally applies: While =~ supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.

To remain portable (in the context of Bash), stick to the POSIX ERE specification.

Note that =~ even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]} array variable.

Further notes:

• $kREGEX_DATE is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).

• While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \.

  • E.g., on Linux, where \< is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes does.

• I've changed variable name REGEX_DATE to kREGEX_DATE (k signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.

Right click on Editor then Select Source -> Generate Getters and Setters or press Alt + Shift + S

You can use this:

<input type="checkbox" [checked]="record.status" (change)="changeStatus(record.id,$event)">

Here, record is the model for current row and status is boolean value.

This regex works perfectly:

bool IsValidEmail(string email)
{
    return Regex.IsMatch(email, @"^[\w!#$%&'*+\-/=?\^_`{|}~]+(\.[\w!#$%&'*+\-/=?\^_`{|}~]+)*@((([\-\w]+\.)+[a-zA-Z]{2,4})|(([0-9]{1,3}\.){3}[0-9]{1,3}))\z");
}

Inside your script file, put all of the commands within parentheses, like this:

(
echo start
ls -l
echo end
) | tee foo.log

tl;dr: The correct way to close a DialogFragment is to use dismiss() directly on the DialogFragment.

Details: The documentation of DialogFragment states

Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.

Thus, you should not use getDialog().dismiss(), since that would invoke dismiss() on the dialog. Instead, you should use the dismiss() method of the DialogFragment itself:

public void dismiss()

Dismiss the fragment and its dialog. If the fragment was added to the back stack, all back stack state up to and including this entry will be popped. Otherwise, a new transaction will be committed to remove the fragment.

As you can see, this takes care not only of closing the dialog but also of handling the fragment transactions involved in the process.

You only need to use onStop if you explicitly created any resources that require manual cleanup (closing files, closing cursors, etc.). Even then, I would override onStop of the DialogFragment rather than onStop of the underlying Dialog.

I just want to point out, you can use .selectedindex to make it a little cleaner

string value = gridview.Rows[gridview.SelectedIndex].Cells[1].Text.ToString();

I hope the below mentioned code will answer your question.

def root(x,a):
    y = 1 / a
    y = float(y)
    print y
    z = x ** y
    print z

base = input("Please input the base value:")
power = float(input("Please input the root value:"))


root(base,power) 

One of the tricks I stumbled upon on the web was using htmlentities then stripping the encoded character :

$stripped = preg_replace('`&[^;]+;`','',htmlentities($string));

Not perfect but it does work well in some case.

But, you're writing about creating an URL string, so urlencode and its counterpart urldecode may be better. Or, if you are creating a query string, use this last function : http_build_query.

Your question is very poorly worded. Your code (sort of) already does what you want. What exactly are you confused about? x.numpy() answer the original title of your question:

Pytorch tensor to numpy array

you need improve your question starting with your title.

Anyway, just in case this is useful to others. You might need to call detach for your code to work. e.g.

RuntimeError: Can't call numpy() on Variable that requires grad.

So call .detach(). Sample code:

# creating data and running through a nn and saving it

import torch
import torch.nn as nn

from pathlib import Path
from collections import OrderedDict

import numpy as np

path = Path('~/data/tmp/').expanduser()
path.mkdir(parents=True, exist_ok=True)

num_samples = 3
Din, Dout = 1, 1
lb, ub = -1, 1

x = torch.torch.distributions.Uniform(low=lb, high=ub).sample((num_samples, Din))

f = nn.Sequential(OrderedDict([
    ('f1', nn.Linear(Din,Dout)),
    ('out', nn.SELU())
]))
y = f(x)

# save data
y.numpy()
x_np, y_np = x.detach().cpu().numpy(), y.detach().cpu().numpy()
np.savez(path / 'db', x=x_np, y=y_np)

print(x_np)

cpu goes after detach. See: https://discuss.pytorch.org/t/should-it-really-be-necessary-to-do-var-detach-cpu-numpy/35489/5

Also I won't make any comments on the slicking since that is off topic and that should not be the focus of your question. See this:

Understanding slice notation

I have used this in the past:

html

January<span class="right">2014</span>

Css

.right {
    margin-left:100%;
}

Demonstration

After I removed

\usepackage{fontspec}% font selecting commands 
\usepackage{xunicode}% unicode character macros 
\usepackage{xltxtra} % some fixes/extras 

it seems to have worked "correctly".

It may be worth noting that the headers and footers only appear from page 2 onwards. Although I've tried the fix for this given in the fancyhdr documentation, I can't get it to work either.

FYI: MikTeX 2.7 under Vista

You can try this method:

<h2 style="text-decoration: underline; text-underline-position: under; text-decoration-style: dotted">Hello World!</h2>

Please note that without text-underline-position: under; you still will have a dotted underline but this property will give it more breathing space.

This is assuming you want to embed everything inside an HTML file using inline styling and not to use a separate CSS file or tag.

Obviously you can't parse N/A to int value. you can do something like following to handle that NumberFormatException .

   String str="N/A";
   try {
        int val=Integer.parseInt(str);
   }catch (NumberFormatException e){
       System.out.println("not a number"); 
   } 

iframe have "sandbox" attribute that may block pop up etc

So what will happen if two threads attack a volatile primitive variable at same time?

Usually each one can increment the value. However sometime, both will update the value at the same time and instead of incrementing by 2 total, both thread increment by 1 and only 1 is added.

Does this mean that whosoever takes lock on it, that will be setting its value first.

There is no lock. That is what synchronized is for.

And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

Yes,

What is the difference between Atomic and volatile keyword?

AtomicXxxx wraps a volatile so they are basically same, the difference is that it provides higher level operations such as CompareAndSwap which is used to implement increment.

AtomicXxxx also supports lazySet. This is like a volatile set, but doesn't stall the pipeline waiting for the write to complete. It can mean that if you read a value you just write you might see the old value, but you shouldn't be doing that anyway. The difference is that setting a volatile takes about 5 ns, bit lazySet takes about 0.5 ns.

There is simple answer in the official guide:

It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.

Paul H's answer is right that you will have to make a second groupby object, but you can calculate the percentage in a simpler way -- just groupby the state_office and divide the sales column by its sum. Copying the beginning of Paul H's answer:

# From Paul H
import numpy as np
import pandas as pd
np.random.seed(0)
df = pd.DataFrame({'state': ['CA', 'WA', 'CO', 'AZ'] * 3,
                   'office_id': list(range(1, 7)) * 2,
                   'sales': [np.random.randint(100000, 999999)
                             for _ in range(12)]})
state_office = df.groupby(['state', 'office_id']).agg({'sales': 'sum'})
# Change: groupby state_office and divide by sum
state_pcts = state_office.groupby(level=0).apply(lambda x:
                                                 100 * x / float(x.sum()))

Returns:

                     sales
state office_id           
AZ    2          16.981365
      4          19.250033
      6          63.768601
CA    1          19.331879
      3          33.858747
      5          46.809373
CO    1          36.851857
      3          19.874290
      5          43.273852

To avoid division by zero!

function x = normalize(x, eps)
    % Normalize vector `x` (zero mean, unit variance)

    % default values
    if (~exist('eps', 'var'))
        eps = 1e-6;
    end

    mu = mean(x(:));

    sigma = std(x(:));
    if sigma < eps
        sigma = 1;
    end

    x = (x - mu) / sigma;
end

Try re-installing with the get-pip script:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

This is sourced from the pip Github page, and worked for me.

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]

1. Are you running this directly in terminal or in a script?
2. How do you run this in a script?

Ad. 1)

Running this directly in terminal means that there will be no subshell created. So you can use either two commands:

source ~/.bash_profile

or

. ~/.bash_profile

In both cases this will update the environment with the contents of .profile file.

Ad 2) You can start any bash script either by calling

sh myscript.sh 

or

. myscript.sh

In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.

In order for your changes applied in your script to have effect for the global environment the script has to be run with

.myscript.sh

command.

In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)

#/bin/bash

preventSubshell(){
  if [[ $_ != $0 ]]
  then
    echo "Script is being sourced"
  else
    echo "Script is a subshell - please run the script by invoking . script.sh command";
    exit 1;
  fi
}

I hope this clears some of the common misunderstandings! :D Good Luck!

I tried to call

startService(oIntent);
bindService(oIntent, mConnection, Context.BIND_AUTO_CREATE);

consequently and I could create a sticky service and bind to it. Detailed tutorial for Bound Service Example.

Use an onclick event, because every click on a checkbox actually changes it.

I had a similar problem. And i had to make it install the same way, we do from pypi.

I did the following things:

1. Make a directory to store all the packages in the machine that have internet access.

   mkdir -p /path/to/packages/
   

2. Download all the packages to the path

Edit: You can also try:

python3 -m pip wheel --no-cache-dir -r requirements.txt -w /path/to/packages

pip download -r requirements.txt -d /path/to/packages

Eg:- ls /root/wheelhouse/  # **/root/wheelhouse** is my **/path/to/packages/**

3. Tar the packages directory and copy it to the Machine that doesn't have internet access. Then do,

   cd /path/to/packages/
   tar -cvzf packages.tar.gz .  # not the . (dot) at the end
   

Copy the packages.tar.gz into the destination machine that doesn't have internet access.

4. In the machine that doesn't have internet access, do the following (Assuming you copied the tarred packages to /path/to/package/ in the current machine)

   cd /path/to/packages/
   tar -xvzf packages.tar.gz
   mkdir -p $HOME/.config/pip/
   vi $HOME/.config/pip/pip.conf
   

and paste the following content inside and save it.

[global]
timeout = 10
find-links = file:///path/to/package/
no-cache-dir = true
no-index = true

5. Finally, i suggest you use, some form of virtualenv for installing the packages.

   virtualenv -p python2 venv # use python3, if you are on python3
   source ./venv/bin/activate
   pip install <package>
   

You should be able to download all the modules that are in the directory /path/to/package/.

Note: I only did this, because i couldn't add options or change the way we install the modules. Otherwise i'd have done

pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt

ILookup Interface is used in .net 3.5 with linq.

The HashTable is the base class that is weakly type; the DictionaryBase abstract class is stronly typed and uses internally a HashTable.

I found a a strange thing about Dictionary, when we add the multiple entries in Dictionary, the order in which the entries are added is maintained. Thus if I apply a foreach on the Dictionary, I will get the records in the same order I have inserted them.

Whereas, this is not true with normal HashTable, as when I add same records in Hashtable the order is not maintained. As far as my knowledge goes, Dictionary is based on Hashtable, if this is true, why my Dictionary maintains the order but HashTable does not?

As to why they behave differently, it's because Generic Dictionary implements a hashtable, but is not based on System.Collections.Hashtable. The Generic Dictionary implementation is based on allocating key-value-pairs from a list. These are then indexed with the hashtable buckets for random access, but when it returns an enumerator, it just walks the list in sequential order - which will be the order of insertion as long as entries are not re-used.

shiv govind Birlasoft.:)

Let's consider I want specific implementation depending on some dynamic state. @Bean is perfect for that case.

@Bean
@Scope("prototype")
public SomeService someService() {
    switch (state) {
    case 1:
        return new Impl1();
    case 2:
        return new Impl2();
    case 3:
        return new Impl3();
    default:
        return new Impl();
    }
}

However there is no way to do that with @Component.

Run the following in zeppelin paragraph

%md ### <span style="color:red">text</span>

Much easier way: use template literals.

var variable = 'foo'
var expression = `.*${variable}.*`
var re = new RegExp(expression, 'g')
re.test('fdjklsffoodjkslfd') // true
re.test('fdjklsfdjkslfd') // false

A list of values quickly? Or even a list of objects!

I am just a beginner at the C# language but I like using

• Hashtable
• Arraylist
• Datatable
• Datasets

etc.

There's just too many ways to store items

I have created a more general function, that sorts more than two lists based on another one, inspired by @Whatang's answer.

def parallel_sort(*lists):
    """
    Sorts the given lists, based on the first one.
    :param lists: lists to be sorted

    :return: a tuple containing the sorted lists
    """

    # Create the initially empty lists to later store the sorted items
    sorted_lists = tuple([] for _ in range(len(lists)))

    # Unpack the lists, sort them, zip them and iterate over them
    for t in sorted(zip(*lists)):
        # list items are now sorted based on the first list
        for i, item in enumerate(t):    # for each item...
            sorted_lists[i].append(item)  # ...store it in the appropriate list

    return sorted_lists

Just remove "build" folder in youy project directory and compile again, i hope it works for you too

You can use LinkedList. It has methods peek, poll and offer.

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

If nginx_ajp_module is used, try adding ajp_read_timeout 10m; in nginx.conf file.

You can do this in the 'Conditional Formatting' tool in the Home tab of Excel 2010.

Assuming the existing rule is 'Use a formula to dtermine which cells to format':

Edit the existing rule, so that the 'Formula' refers to relative rows and columns (i.e. remove $s), and then in the 'Applies to' box, click the icon to make the sheet current and select the cells you want the formatting to apply to (absolute cell references are ok here), then go back to the tool panel and click Apply.

This will work assuming the relative offsets are appropriate throughout your desired apply-to range.

You can copy conditional formatting from one cell to another or a range using copy and paste-special with formatting only, assuming you do not mind copying the normal formats.

In my case, another developer had removed some of the tables from the underlying database. When I realised this, and removed these tables from the entity, the problem was solved. Wasn't as obvious as it sounds.

I combined the solutions by Micah Hainline, Alex Balu?, and Paul Imhoff to create an ellipsizing multiline TextView that also supports Spanned text.

You only need to set android:ellipsize and android:maxLines.

Swift 2 and below

let date = NSDate()
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.stringFromDate(date)
println(dateString)

And in Swift 3 and higher this would now be written as:

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.string(from: date)

According to Apple's Data Formatting Guide

Creating a date formatter is not a cheap operation. If you are likely to use a formatter frequently, it is typically more efficient to cache a single instance than to create and dispose of multiple instances. One approach is to use a static variable

And while I agree with @Leon that this should be failable initializer, when you enter seed data, we could have one that isn't failable (just like there is UIImage(imageLiteralResourceName:)).

So here's my approach:

extension DateFormatter {
  static let yyyyMMdd: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"
    formatter.calendar = Calendar(identifier: .iso8601)
    formatter.timeZone = TimeZone(secondsFromGMT: 0)
    formatter.locale = Locale(identifier: "en_US_POSIX")
    return formatter
  }()
}

extension Date {
    init?(yyyyMMdd: String) {
        guard let date = DateFormatter.yyyyMMdd.date(from: yyyyMMdd) else { return nil }
        self.init(timeInterval: 0, since: date)
    }

    init(dateLiteralString yyyyMMdd: String) {
        let date = DateFormatter.yyyyMMdd.date(from: yyyyMMdd)!
        self.init(timeInterval: 0, since: date)
    }
}

And now enjoy simply calling:

// For seed data
Date(dateLiteralString: "2020-03-30")

// When parsing data
guard let date = Date(yyyyMMdd: "2020-03-30") else { return nil }

If you have it in a string, you can use .split() to separate them.

>>> for string in ('Mike 18', 'Kevin 35', 'Angel 56'):
...   l = string.split()
...   print repr(l[0]), repr(int(l[1]))
...
'Mike' 18
'Kevin' 35
'Angel' 56
>>>

public static void main(String args[])
{
    Scanner s = new Scanner(System.in);

    System.out.println("Press enter to continue.....");

    s.nextLine();   
}

This nextline is a pretty good option as it will help us run next line whenever the enter key is pressed.

You can stash your local changes first, then pull, then pop the stash.

git stash
git pull origin master
git stash pop

Anything that overrides changes from remote will have conflicts which you will have to manually resolve.

Building on Luiz's answer, but satisfying the "in case of draws the item with the lowest index should be returned" condition:

from statistics import mode, StatisticsError

def most_common(l):
    try:
        return mode(l)
    except StatisticsError as e:
        # will only return the first element if no unique mode found
        if 'no unique mode' in e.args[0]:
            return l[0]
        # this is for "StatisticsError: no mode for empty data"
        # after calling mode([])
        raise

Example:

>>> most_common(['a', 'b', 'b'])
'b'
>>> most_common([1, 2])
1
>>> most_common([])
StatisticsError: no mode for empty data

I'm using EF6, and I find something strange,

Suppose Customer has constructor with parameter ,

if I use new Customer(id, "name"), and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name") );
    db.SaveChanges();
 }

It run through without error, but when I look into the DataBase, I find in fact that the data Is NOT be Inserted,

But if I add the curly brackets, use new Customer(id, "name"){} and do

 using (var db = new EfContext("name=EfSample"))
 {
    db.Customers.Add( new Customer(id, "name"){} );
    db.SaveChanges();
 }

the data will then actually BE Inserted,

seems the Curly Brackets make the difference, I guess that only when add Curly Brackets, entity framework will recognize this is a real concrete data.

Even with a default value, you can always override the column data with null.

The NOT NULL restriction won't let you update that row after it was created with null value

For VB.Net is

        Dim con As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + "database path")
        Dim cmd As New OleDb.OleDbCommand
        Dim dt As New DataTable
        Dim da As New OleDb.OleDbDataAdapter
        con.Open()
        cmd.Connection = con
        cmd.CommandText = sql
        da.SelectCommand = cmd

        da.Fill(dt)

        For i As Integer = 0 To dt.Rows.Count
            someVar = dt.Rows(i)("fieldName")
        Next

Try this

INSERT INTO dbo.DB1.TempTable
    (COLUMNS)
    SELECT COLUMNS_IN_SAME_ORDER FROM dbo.DB2.TempTable

This will only fail if an item in dbo.DB2.TempTable is in already in dbo.DB1.TempTable.

You could define a clone function.

I use this one :

function goclone(source) {
    if (Object.prototype.toString.call(source) === '[object Array]') {
        var clone = [];
        for (var i=0; i<source.length; i++) {
            clone[i] = goclone(source[i]);
        }
        return clone;
    } else if (typeof(source)=="object") {
        var clone = {};
        for (var prop in source) {
            if (source.hasOwnProperty(prop)) {
                clone[prop] = goclone(source[prop]);
            }
        }
        return clone;
    } else {
        return source;
    }
}

var B = goclone(A);

It doesn't copy the prototype, functions, and so on. But you should adapt it (and maybe simplify it) for you own need.

Personally, I would print them to a file using Perl or Python in the format

<COL_NAME>:  <COL_VAL>

for each row so that the file has as many lines as there are columns. Then I'd do a diff between the two files, assuming you are on Unix or compare them using some equivalent utilty on another OS. If you have multiple recordsets (i.e. more than one row), I would prepend to each file row and then the file would have NUM_DB_ROWS * NUM_COLS lines

Unfortunately I can't comment the answer from geza.

He is not just saying "put forward declarations into a separate header". He says that you have to spilt class definition headers and inline function definitions into different header files to allow "defered dependencies".

But his illustration is not really good. Because both classes (A and B) only need an incomplete type of each other (pointer fields / parameters).

To understand it better imagine that class A has a field of type B not B*. In addition class A and B want to define an inline function with parameters of the other type:

This simple code would not work:

// A.h
#pragme once
#include "B.h"

class A{
  B b;
  inline void Do(B b);
}

inline void A::Do(B b){
  //do something with B
}

// B.h
#pragme once
class A;

class B{
  A* b;
  inline void Do(A a);
}

#include "A.h"

inline void B::Do(A a){
  //do something with A
}

//main.cpp
#include "A.h"
#include "B.h"

It would result in the following code:

//main.cpp
//#include "A.h"

class A;

class B{
  A* b;
  inline void Do(A a);
}

inline void B::Do(A a){
  //do something with A
}

class A{
  B b;
  inline void Do(B b);
}

inline void A::Do(B b){
  //do something with B
}
//#include "B.h"

This code does not compile because B::Do needs a complete type of A which is defined later.

To make sure that it compiles the source code should look like this:

//main.cpp
class A;

class B{
  A* b;
  inline void Do(A a);
}

class A{
  B b;
  inline void Do(B b);
}

inline void B::Do(A a){
  //do something with A
}

inline void A::Do(B b){
  //do something with B
}

This is exactly possible with these two header files for each class wich needs to define inline functions. The only issue is that the circular classes can't just include the "public header".

To solve this issue I would like to suggest a preprocessor extension: #pragma process_pending_includes

This directive should defer the processing of the current file and complete all pending includes.

Here is the App Bit Web Server (PHP,MySQL,PMA)

It can run a variety of CMS like Wordpress, Joomla, Drupal, Prestashop, etc. Besides CMS can also run PHP frameworks like Code Igniter, YII, CakePHP, etc. It is the same as WAMP or LAMP or XAMPP on your computer or laptop, but this is for android devices with lighttpd instead of apache.

I made a small function that might be useful based off of the answer provided by @gawi (above).

removeBranchesWithPrefix() {
  git for-each-ref --format="%(refname:short)" refs/heads/$1\* | xargs git branch -d
}

Add that to your .bash_profile and restart your terminal. Then you can call from command-line like this:

removeBranchesWithPrefix somePrefix

Note

I have it currently setup for a soft delete, which means it won't delete the branches unless they've already been merged. If you like to live on the edge, change -d to -D and it will delete everything with the prefix regardless!

I'am trying to install SQL SERVER developer 2008 R2 alongside SQL SERVER 2005 EXPRESS,

i went to program features, clicked on unistall SQL SERVER 2005 EXPRESS, and only checked, WORKSTATION COMPONENTS, it unistalled: support files, sql mngmt studio

After that installation of sql 2008 r2 developer went ok....

Hopes this helps somebody

var promise = $interval(function(){
    if($location.path() == '/landing'){
        $rootScope.$emit('testData',"test");
        $interval.cancel(promise);
    }
},2000);

I was playing with this and came up with an alternative.

$ VAR=/home/me/mydir/file.c

$ DIR=`echo $VAR |xargs dirname`

$ echo $DIR
/home/me/mydir

The part I liked is it was easy to extend backup the tree:

$ DIR=`echo $VAR |xargs dirname |xargs dirname |xargs dirname`

$ echo $DIR
/home

JSON.stringify's third parameter defines white-space insertion for pretty-printing. It can be a string or a number (number of spaces). Node can write to your filesystem with fs. Example:

var fs = require('fs');

fs.writeFile('test.json', JSON.stringify({ a:1, b:2, c:3 }, null, 4));
/* test.json:
{
     "a": 1,
     "b": 2,
     "c": 3,
}
*/

See the JSON.stringify() docs at MDN, Node fs docs

You can download tika-app-xxx.jar(latest) from Here.

Then put this .jar file in the same folder of your python script file.

then insert the following code in the script:

import os
import os.path

tika_dir=os.path.join(os.path.dirname(__file__),'<tika-app-xxx>.jar')

def extract_pdf(source_pdf:str,target_txt:str):
    os.system('java -jar '+tika_dir+' -t {} > {}'.format(source_pdf,target_txt))

The advantage of this method:

fewer dependency. Single .jar file is easier to manage that a python package.

multi-format support. The position source_pdf can be the directory of any kind of document. (.doc, .html, .odt, etc.)

up-to-date. tika-app.jar always release earlier than the relevant version of tika python package.

stable. It is far more stable and well-maintained (Powered by Apache) than PyPDF.

disadvantage:

A jre-headless is necessary.

Try this.In html you write the following code.

<select class="select2" multiple="multiple" placeholder="Select State">
    <option value="AK">Alaska</option>
    <option value="HI">Hawaii</option>
</select>

And in your script write the below code.Keep in mind that have the link of select2js.

<script>
         $( ".select2" ).select2( { } );
 </script>

All objects are instances of at least one class – Object – in ECMAScript. You can only differentiate between instances of built-in classes and normal objects using Object#toString. They all have the same level of complexity, for instance, whether they are created using {} or the new operator.

Object.prototype.toString.call(object) is your best bet to differentiate between normal objects and instances of other built-in classes, as object === Object(object) doesn't work here. However, I can't see a reason why you would need to do what you're doing, so perhaps if you share the use case I can offer a little more help.

Chris Dents' answer has already covered the OPs' question but seeing as this was the top search on google for PowerShell format string as date I thought I'd give a different string example.

If like me, you get the time string like this 20190720170000.000000+000

An important thing to note is you need to use ToUniversalTime() when using [System.Management.ManagementDateTimeConverter] otherwise you get offset times against your input.

PS Code

cls
Write-Host "This example is for the 24hr clock with HH"
Write-Host "ToUniversalTime() must be used when using [System.Management.ManagementDateTimeConverter]"
$my_date_24hr_time   = "20190720170000.000000+000"

Ultimately was able to figure it out , i just hope it will help someone like me.
Following is how the web pack config file should look like check the dist dir and output file specified. I was missing the way to specify the path of dist directory

const webpack = require('webpack');
const path = require('path');
var config = {
    entry: './main.js',

    output: {
        path: path.join(__dirname, '/dist'),
        filename: 'index.js',
    },

    devServer: {
        inline: true,
        port: 8080
    },
    resolveLoader: {
        modules: [path.join(__dirname, 'node_modules')]
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel-loader',

                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    },
}

module.exports = config;

Then the package json file

{
  "name": "reactapp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack --progress",
    "production": "webpack -p --progress"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "webpack": "^2.2.1"
  },
  "devDependencies": {
    "babel-core": "^6.0.20",
    "babel-loader": "^6.0.1",
    "babel-preset-es2015": "^6.0.15",
    "babel-preset-react": "^6.0.15",
    "babel-preset-stage-0": "^6.0.15",
    "express": "^4.13.3",
    "webpack": "^1.9.6",
    "webpack-devserver": "0.0.6"
  }
}

Notice the script section and production section, production section is what gives you the final deployable index.js file ( name can be anything )

Rest fot the things will depend upon your code and components

Execute following sequence of commands

npm install

this should get you all the dependency (node modules)

then

npm run production

this should get you the final index.js file which will contain all the code bundled

Once done place index.html and index.js files under www/html or the web app root directory and that's all.

Minor variation to user1850980's answer (for the question "How to initialize a list of empty dictionaries") using list constructor:

dictlistGOOD = list( {} for i in xrange(listsize) )

I found out to my chagrin, this does NOT work:

dictlistFAIL = [{}] * listsize  # FAIL!

as it creates a list of references to the same empty dictionary, so that if you update one dictionary in the list, all the other references get updated too.

Try these updates to see the difference:

dictlistGOOD[0]["key"] = "value"
dictlistFAIL[0]["key"] = "value"

(I was actually looking for user1850980's answer to the question asked, so his/her answer was helpful.)

You can use the --append feature of tee:

cat file01.txt | tee --append bothFiles.txt 
cat file02.txt | tee --append bothFiles.txt 

Or shorter,

cat file01.txt file02.txt | tee --append bothFiles.txt 

I assume the request for no redirection (>>) comes from the need to use this in xargs or similar. So if that doesn't count, you can mute the output with >/dev/null.

What version of the framework? With 3.5 you could presumably use:

List<ManagementObject> managementList = managementObjects.Cast<ManagementObject>().ToList();

(edited to remove simpler version; I checked and ManagementObjectCollection only implements the non-generic IEnumerable form)

I find a good solution for this issue, this solution can make it work and no need to recreate Fragments.
My key point is:

1. setup ViewPager every time you delete or add Tab(Fragment).
2. Override the getItemId method, return a specific id rather than position.

You need to add the following line:

using FootballLeagueSystem;

into your all your classes (MainMenu.cs, programme.cs, etc.) that use Login.

At the moment the compiler can't find the Login class.

Update:

I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.

We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.

The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:

1. Timestamp: time that request is sent (UTC or GMT)
2. HTTP verb: GET, POST, PUT, DELETE.
3. post data and query string,
4. URL

Under the hood, HMAC authentication would be:

Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:

User-Agent: {agent}   
Host: {host}   
Timestamp: {timestamp}
Authentication: {username}:{signature}

Example for GET request:

GET /webapi.hmac/api/values

User-Agent: Fiddler    
Host: localhost    
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

The message to hash to get signature:

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n

Example for POST request with query string (signature below is not correct, just an example)

POST /webapi.hmac/api/values?key2=value2

User-Agent: Fiddler    
Host: localhost    
Content-Type: application/x-www-form-urlencoded
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

key1=value1&key3=value3

The message to hash to get signature

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
key1=value1&key2=value2&key3=value3

Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.

When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.

The secret key is got from the database with the username on the request.

Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.

The code to build signature:

private static string ComputeHash(string hashedPassword, string message)
{
    var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
    string hashString;

    using (var hmac = new HMACSHA256(key))
    {
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
        hashString = Convert.ToBase64String(hash);
    }

    return hashString;
}

So, how to prevent replay attack?

Add constraint for the timestamp, something like:

servertime - X minutes|seconds  <= timestamp <= servertime + X minutes|seconds 

(servertime: time of request coming to server)

And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.

The demo code is put as here: https://github.com/cuongle/Hmac.WebApi

Update PC Drivers

In my case, and I had bad lag doing the simplest of things, it helped to update my pc drivers. The system drivers are the foundation for everything.

I was fortunate that I have Dell and they have awesome website support to do this. I googled

dell <my model name> update drivers

or go to the drivers home page

I let it update all the drivers it wanted to (Dell driver update is pretty much automatic).

Much of the lag seems to have gone away.

For OSX: pip install scikit-image

and then run python to try following

from skimage.feature import corner_harris, corner_peaks

It's not basic css, but if you're using LESS (http://lesscss.org), you can do this using recursion:

.hClass (@index) when (@index > 0) {
    h@{index} {
        font: 32px/42px trajan-pro-1,trajan-pro-2;
    }
    .hClass(@index - 1);
}
.hClass(6);

Sass (http://sass-lang.com) will allow you to manage this, but won't allow recursion; they have @for syntax for these instances:

@for $index from 1 through 6 {
  h#{$index}{
    font: 32px/42px trajan-pro-1,trajan-pro-2;
  }
}

If you're not using a dynamic language that compiles to CSS like LESS or Sass, you should definitely check out one of these options. They can really simplify and make more dynamic your CSS development.

I just wrote my little subclass of UIView that has ability to produce native iOS 7 blur on any custom view. It uses UIToolbar but in a safe way for changing it's frame, bounds, color and alpha with real-time animation.

Please let me know if you notice any problems.

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

var example = $('#exampleTable').DataTable({
    "columnDefs": [
        {
            "targets": [0],
            "visible": false,
            "searchable": false
        }
    ]
});

Target attribute defines the position of the column.Visible attribute responsible for visibility of the column.Searchable attribute responsible for searching facility.If it set to false that column doesn't function with searching.

kk: (01-24) will look like 01, 02..24.

HH:(00-23) will look like 00, 01..23.

hh:(01-12 in AM/PM) will look like 01, 02..12.

so the last printout (working2) is a bit weird. It should say 12:00:00 (edit: if you were setting the working2 timezone and format, which (as kdagli pointed out) you are not)

Or better

window.location.assign("relative or absolute address");

that tends to work best across all browsers and mobile

N.B. - this question and answer relate to the 2000 version of SQL Server. In later versions, the restriction on INSERT INTO @table_variable ... EXEC ... were lifted and so it doesn't apply for those later versions.

You'll have to switch to a temp table:

CREATE TABLE #tmp (code varchar(50), mount money)

From the documentation:

A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.

Within its scope, a table variable may be used like a regular table. It may be applied anywhere a table or table expression is used in SELECT, INSERT, UPDATE, and DELETE statements. However, table may not be used in the following statements:

INSERT INTO table_variable EXEC stored_procedure

SELECT select_list INTO table_variable statements.

The -p flag of netstat gives you PID of the process:

netstat -l -p

Edit: The command that is needed to get PIDs of socket users in FreeBSD is sockstat. As we worked out during the discussion with @Cyclone, the line that does the job is:

sockstat -4 -l | grep :80 | awk '{print $3}' | head -1

If you are facing the "This certificate has an invalid issuer" error for all your certificates then do the following steps.

Steps:

• Open Keychain and Click on Login -> All Items from the left panel.
• Now, Click on View -> Show Expired Certificates from the top navigation menu.
• Now search for "Apple Worldwide Developer Relations Certification Authority" and delete expired certificates.
• After deleting expired certificates, visit the following URL and download the new certificate, https://developer.apple.com/certificationauthority/AppleWWDRCA.cer.
• Double click on the newly downloaded certificate, and install it in your keychain.
• Double check: List expired certificates by following step number 3.
• Now you have a valid "Apple Worldwide Developer Relations Certification Authority" having expiry date 2023-02-07.

Reference:

• Apple Worldwide Developer Relations Intermediate Certificate Expiration

Add

div.ui-datepicker, .ui-datepicker td{
 font-size:10px;
}

in a stylesheet loaded after the ui-files. This will also resize the date items.

UPD: updated to state Lifecycle.State.RESUMED. Thanks to @htafoya for that.

In 2019 with help of new support library 28+ or AndroidX you can simply use:

val isActivityInForeground = activity.lifecycle.currentState.isAtLeast(Lifecycle.State.RESUMED)

You can read more in the documenation to understand what happened under the hood.

Simplest Explanation:

Module is like a big container containing one or many small containers called Component, Service, Pipe

A Component contains :

• HTML template or HTML code

• Code(TypeScript)

• Service: It is a reusable code that is shared by the Components so that rewriting of code is not required

• Pipe: It takes in data as input and transforms it to the desired output

Reference: https://scrimba.com/

var floatValue = 10.23
var intValue = Int(floatValue)

This is enough to convert from float to Int

SELECT <select_list> 
FROM Table_A A
LEFT JOIN Table_B B
ON A.Key = B.Key
WHERE B.Key IS NULL

check the /tmp/tmp/server.pid

there is a pid inside.

Usually, I ill do "kill -9 THE_PID" in the cmd

It's unprofessional, anyway this will work with javascript enabled:

document.oncontextmenu = document.body.oncontextmenu = function() {return false;}

You may also want to show a message to the user before returning false.

However I have to say that this should not be done generally because it limits users options without resolving the issue (in fact the context menu can be very easily enabled again.).

The following article better explains why this should not be done and what other actions can be taken to solve common related issues: http://articles.sitepoint.com/article/dont-disable-right-click

I know this may be a bit too late but the most efficient way of doing this through a CTE as follows:

 WITH Months AS
    (
       SELECT 1 x
       UNION all
       SELECT x + 1
       FROM Months
       WHERE x < 12

     )
     SELECT x AS MonthNumber, DateName( month , DateAdd( month , x , -1 ))            AS MonthName FROM Months

you should use

double g=1.0/3;

or

double g=1/3.0;

Integer division returns integer.

why not simply

new Date (timestamp);

A date is a date, the formatting of it is a different matter.

Update October 2019

The following should work "stand-alone" on all modern browsers without any dependencies or transpilation.

<!-- display a pop-up with the selected values from the <select> element -->

<script>
 const showSelectedOptions = options => alert(
   [...options].filter(o => o.selected).map(o => o.value)
 )
</script>

<select multiple onchange="showSelectedOptions(this.options)">
  <option value='1'>one</option>
  <option value='2'>two</option>
  <option value='3'>three</option>
  <option value='4'>four</option>
</select>

Using underscore you can use _.pairs to get the first object entry as a key value pair as follows:

_.pairs(obj)[0]

Then the key would be available with a further [0] subscript, the value with [1]

Here is a simple letter-range implementation:

Code

def letter_range(start, stop="{", step=1):
    """Yield a range of lowercase letters.""" 
    for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
        yield chr(ord_)

Demo

list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']

list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']

When you use QDir.mkpath() it returns true if the path already exists, in the other hand QDir.mkdir() returns false if the path already exists. So depending on your program you have to choose which fits better.

You can see more on Qt Documentation

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

You can do this all in the File.open block:

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
playlist_name = gets.chomp + '.m3u'

File.open playlist_name, 'w' do |f|
  music.each do |z|
    f.puts z
  end
end

select substring( field, 1, 5 ) from sometable

This works for me, I hope helps to someone.

var frm = $('#frm');
let formData = new FormData(frm[0]);
axios.post('your-url', formData)
    .then(res => {
        console.log({res});
    }).catch(err => {
        console.error({err});
    });

You should use the "siblings()" method, and prevent from running the ".content a" selector over and over again just for applying that effect:

HTML

<div class="content">
    <a href="#">A</a>
</div>
<div class="content">
    <a href="#">B</a>
</div>
<div class="content">
    <a href="#">C</a>
</div>

CSS

.content {
    background-color:red;
    margin:10px;
}
.content.other {
    background-color:yellow;
}

Javascript

$(".content a").click(function() {
  var current = $(this).parent();
  current.removeClass('other')
    .siblings()
    .addClass('other');
});

See here: http://jsfiddle.net/3bzLV/1/

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

If a is a prime then the while x: in your code will run forever, since x will remain True.

So why is that while there?

I think you wanted to end the for loop when you found a factor, but didn't know how, so you added that while since it has a condition. So here is how you do it:

def is_prime(a):
    x = True 
    for i in range(2, a):
       if a%i == 0:
           x = False
           break # ends the for loop
       # no else block because it does nothing ...


    if x:
        print "prime"
    else:
        print "not prime"

You can use the $$ variable.

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

for each string in your list, use .strip() which removes whitespace from the beginning or end of the string:

for i in contents:
    alist.append(i.strip())

But depending on your use case, you might be better off using something like numpy.loadtxt or even numpy.genfromtxt if you need a nice array of the data you're reading from the file.

How do I declare an ES6 Map type in typescript?

You need to target --module es6. This is misfortunate and you can raise your concern here : https://github.com/Microsoft/TypeScript/issues/2953#issuecomment-98514111
