I got the same error and I solved this by :

1. Apply command from cmd (run as administrator)

   git config --system --unset credential.helper

2. And then I removed gitconfig file from C:\Program Files\Git\mingw64/etc/ location (Note: this path will be different in MAC like "/Users/username")

3. After that use git command like git pull or git push, it asked me for username and password. applying valid username and password and git command working.

hope this will help you...

Now that I look closer, I think that the DataSource problem is a red-herring. Boot's Hibernate auto-configuration is being triggered and that's what causing a DataSource to be required. Hibernate's on the classpath because you've got a dependency on spring-boot-starter-data-jpa which pulls in hibernate-entitymanager.

Update your spring-boot-starter-data-jpa dependency to exclude Hibernate:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-entitymanager</artifactId>
        </exclusion>
    </exclusions>
</dependency>

i download the missing jar and placed in the .m2 repository fixed the problem =]

If you called setText before and the new text didn't get layout phase call setSelection in a separate runnable fired by View.post(Runnable) (repost from this topic).

So, for me this code works:

editText.setText("text");
editText.post(new Runnable() {
         @Override
         public void run() {
             editText.setSelection(editText.getText().length());
         }
});

Edit 05/16/2019: Right now I'm using Kotlin extension for that:

fun EditText.placeCursorToEnd() {
    this.setSelection(this.text.length)
}

and then - editText.placeCursorToEnd().

def solution(A, K):
    if len(A) == 0:
        return A

    K = K % len(A)

    return A[-K:] + A[:-K]

# use case
A = [1, 2, 3, 4, 5, 6]
K = 3
print(solution(A, K))

For example, given

A = [3, 8, 9, 7, 6]
K = 3

the function should return [9, 7, 6, 3, 8]. Three rotations were made:

[3, 8, 9, 7, 6] -> [6, 3, 8, 9, 7]
[6, 3, 8, 9, 7] -> [7, 6, 3, 8, 9]
[7, 6, 3, 8, 9] -> [9, 7, 6, 3, 8]

For another example, given

A = [0, 0, 0]
K = 1

the function should return [0, 0, 0]

Given

A = [1, 2, 3, 4]
K = 4

the function should return [1, 2, 3, 4]

You can simply add following file to your tests directory, and then python will run it before the tests

__init__.py file

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

pull = fetch + merge.

You need to commit what you have done before merging.

So pull after commit.

you can use @see to do that:

sample:

interface View {
        /**
         * @return true: have read contact and call log permissions, else otherwise
         * @see #requestReadContactAndCallLogPermissions()
         */
        boolean haveReadContactAndCallLogPermissions();

        /**
         * if not have permissions, request to user for allow
         * @see #haveReadContactAndCallLogPermissions()
         */
        void requestReadContactAndCallLogPermissions();
    }

I'm surprised there's been no mention of filter_var here for this being such an old question...

PHP has a built in method of doing this using sanitization filters. Specifically, the one to use in this situation is FILTER_SANITIZE_NUMBER_FLOAT with the FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND flags. Like so:

$numeric_filtered = filter_var("AR3,373.31", FILTER_SANITIZE_NUMBER_FLOAT,
    FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);
echo $numeric_filtered; // Will print "3,373.31"

It might also be worthwhile to note that because it's built-in to PHP, it's slightly faster than using regex with PHP's current libraries (albeit literally in nanoseconds).

The biggest problem with a batch script is handling rollback when the user clicks cancel (or something goes wrong during your install). The correct way to handle this scenario is to create a CustomAction that adds temporary rows to the RemoveFiles table. That way the Windows Installer handles the rollback cases for you. It is insanely simpler when you see the solution.

Anyway, to have an action only execute during uninstall add a Condition element with:

REMOVE ~= "ALL"

the ~= says compare case insensitive (even though I think ALL is always uppercaesd). See the MSI SDK documentation about Conditions Syntax for more information.

PS: There has never been a case where I sat down and thought, "Oh, batch file would be a good solution in an installation package." Actually, finding an installation package that has a batch file in it would only encourage me to return the product for a refund.

This accomplishes the same thing but is much simpler:

$(document).ready(function() {  
   $("#board").delay(1000).append(".");
});

You can chain a delay before almost any jQuery method.

shape is a tuple that gives dimensions of the array..

>>> c = arange(20).reshape(5,4)
>>> c
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11],
       [12, 13, 14, 15],
       [16, 17, 18, 19]])

c.shape[0] 
5

Gives the number of rows

c.shape[1] 
4

Gives number of columns

You need to follow the steps described in Troubleshooting: Connecting to SQL Server When System Administrators Are Locked Out and add your own Windows user as a member of sysadmin:

• shutdown MSSQL$EXPRESS service (or whatever the name of your SQL Express service is)
• start add the -m and -f startup parameters (or you can start sqlservr.exe -c -sEXPRESS -m -f from console)
• connect to DAC: sqlcmd -E -A -S .\EXPRESS or from SSMS use admin:.\EXPRESS
• run create login [machinename\username] from windows to create your Windows login in SQL
• run sp_addsrvrolemember 'machinename\username', 'sysadmin'; to make urself sysadmin member
• restart service w/o the -m -f

Use SqlCommand.ExecuteScalar() and cast it to an int:

cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();

if sum of column is 0 then display empty

select if(sum(column)>0,sum(column),'')
from table 

Perhaps you should divide your content like such using floats:

<div style="overflow: auto;">
    <div style="float: left; width: 600px;">
        Here is my content!
    </div>
    <div style="float: right; width: 300px;">
        Here is my sidebar!
    </div>
</div>

Notice the overflow: auto;, this is to ensure that you have some height to your container. Floating things takes them out of the DOM, to ensure that your elements below don't overlap your wandering floats, set a container div to have an overflow: auto (or overflow: hidden) to ensure that floats are accounted for when drawing your height. Check out more information on floats and how to use them here.

1. Remove all files from migrations folder.

2. Type in console

   dotnet ef database drop -f -v
   dotnet ef migrations add Initial

UPD: Do that only if you don't care about your current persisted data. If you do, use Greg Gum's answer

Here's a solid example of how a self invoking anonymous function could be useful.

for( var i = 0; i < 10; i++ ) {
  setTimeout(function(){
    console.log(i)
  })
}

Output: 10, 10, 10, 10, 10...

for( var i = 0; i < 10; i++ ) {
  (function(num){
    setTimeout(function(){
      console.log(num)
    })
  })(i)
}

Output: 0, 1, 2, 3, 4...

Use application/javascript as content type instead of text/javascript

text/javascript is mentioned obsolete. See reference docs.

http://www.iana.org/assignments/media-types/application

Also see this question on SO.

UPDATE:

I have tried executing the code you have given and the below didn't work.

res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);

This is what worked for me.

res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);

As robertklep has suggested, please refer to the node http docs, there is no response.send() there.

There is no difference, except that Pragma is only defined as applicable to the requests by the client, whereas Cache-Control may be used by both the requests of the clients and the replies of the servers.

So, as far as standards go, they can only be compared from the perspective of the client making a requests and the server receiving a request from the client. The http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32 defines the scenario as follows:

HTTP/1.1 caches SHOULD treat "Pragma: no-cache" as if the client had sent "Cache-Control: no-cache". No new Pragma directives will be defined in HTTP.

  Note: because the meaning of "Pragma: no-cache as a response
  header field is not actually specified, it does not provide a
  reliable replacement for "Cache-Control: no-cache" in a response

The way I would read the above:

• if you're writing a client and need no-cache:

  • just use Pragma: no-cache in your requests, since you may not know if Cache-Control is supported by the server;
  • but in replies, to decide on whether to cache, check for Cache-Control

• if you're writing a server:

  • in parsing requests from the clients, check for Cache-Control; if not found, check for Pragma: no-cache, and execute the Cache-Control: no-cache logic;
  • in replies, provide Cache-Control.

Of course, reality might be different from what's written or implied in the RFC!

Using CentOS Linux I found that the easiest syntax would be:

wget "link" -O file.ext

where "link" is the web address you want to save and "file.ext" is the filename and extension of your choice.

I just experienced this. I had read the suggestions on this page, as well as the SQL Authority suggestions (which is the same thing) and none of the above worked.

In the end, I removed the account and recreated (with the same username/password). Just like that, all the issues went away.

Sadly, this means I don't know what went wrong so I can't share any thing else.

(You're not searching through "JSON", you're searching through an array -- the JSON string has already been deserialized into an object graph, in this case an array.)

Some options:

Use an Object Instead of an Array

If you're in control of the generation of this thing, does it have to be an array? Because if not, there's a much simpler way.

Say this is your original data:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

Could you do the following instead?

{
    "one":   {"pId": "foo1", "cId": "bar1"},
    "two":   {"pId": "foo2", "cId": "bar2"},
    "three": {"pId": "foo3", "cId": "bar3"}
}

Then finding the relevant entry by ID is trivial:

id = "one"; // Or whatever
var entry = objJsonResp[id];

...as is updating it:

objJsonResp[id] = /* New value */;

...and removing it:

delete objJsonResp[id];

This takes advantage of the fact that in JavaScript, you can index into an object using a property name as a string -- and that string can be a literal, or it can come from a variable as with id above.

Putting in an ID-to-Index Map

(Dumb idea, predates the above. Kept for historical reasons.)

It looks like you need this to be an array, in which case there isn't really a better way than searching through the array unless you want to put a map on it, which you could do if you have control of the generation of the object. E.g., say you have this originally:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

The generating code could provide an id-to-index map:

{
    "index": {
        "one": 0, "two": 1, "three": 2
    },
    "data": [
        {"id": "one",   "pId": "foo1", "cId": "bar1"},
        {"id": "two",   "pId": "foo2", "cId": "bar2"},
        {"id": "three", "pId": "foo3", "cId": "bar3"}
    ]
}

Then getting an entry for the id in the variable id is trivial:

var index = objJsonResp.index[id];
var obj = objJsonResp.data[index];

This takes advantage of the fact you can index into objects using property names.

Of course, if you do that, you have to update the map when you modify the array, which could become a maintenance problem.

But if you're not in control of the generation of the object, or updating the map of ids-to-indexes is too much code and/ora maintenance issue, then you'll have to do a brute force search.

Brute Force Search (corrected)

Somewhat OT (although you did ask if there was a better way :-) ), but your code for looping through an array is incorrect. Details here, but you can't use for..in to loop through array indexes (or rather, if you do, you have to take special pains to do so); for..in loops through the properties of an object, not the indexes of an array. Your best bet with a non-sparse array (and yours is non-sparse) is a standard old-fashioned loop:

var k;
for (k = 0; k < someArray.length; ++k) { /* ... */ }

or

var k;
for (k = someArray.length - 1; k >= 0; --k) { /* ... */ }

Whichever you prefer (the latter is not always faster in all implementations, which is counter-intuitive to me, but there we are). (With a sparse array, you might use for..in but again taking special pains to avoid pitfalls; more in the article linked above.)

Using for..in on an array seems to work in simple cases because arrays have properties for each of their indexes, and their only other default properties (length and their methods) are marked as non-enumerable. But it breaks as soon as you set (or a framework sets) any other properties on the array object (which is perfectly valid; arrays are just objects with a bit of special handling around the length property).

Guys why bother with all the faff. This works perfectly. No code required

The message "DL is deprecated, please use Fiddle" is not an error; it's only a warning.
Solution:
You can ignore this in 3 simple steps.
Step 1. Goto C:\RailsInstaller\Ruby2.1.0\lib\ruby\2.1.0
Step 2. Then find dl.rb and open the file with any online editors like Aptana,sublime text etc
Step 3. Comment the line 8 with '#' ie # warn "DL is deprecated, please use Fiddle" .
That's it, Thank you.

I up-voted "Nathan Wheeler" answer as I found "Cade Roux" answer did not work above a certain string size.

Couple of points

-I found adding the DISTINCT keyword improved performance for me.

-Nathan's answer only works if your identifiers are 5 characters or less, of course you can adjust that...If the items you are splitting are INT identifiers as I am you can us same as me below:

CREATE FUNCTION [dbo].Split
(
    @sep VARCHAR(32), 
    @s VARCHAR(MAX)
)
RETURNS 
    @result TABLE (
        Id INT NULL
    )   
AS
BEGIN
    DECLARE @xml XML
    SET @XML = N'<root><r>' + REPLACE(@s, @sep, '</r><r>') + '</r></root>'

    INSERT INTO @result(Id)
    SELECT DISTINCT r.value('.','int') as Item
    FROM @xml.nodes('//root//r') AS RECORDS(r)

    RETURN
END

Like this:

List<String> list = new ArrayList<String>();

String[] a = list.toArray(new String[0]);

Before Java6 it was recommended to write:

String[] a = list.toArray(new String[list.size()]);

because the internal implementation would realloc a properly sized array anyway so you were better doing it upfront. Since Java6 the empty array is preferred, see .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])?

If your list is not properly typed you need to do a cast before calling toArray. Like this:

    List l = new ArrayList<String>();

    String[] a = ((List<String>)l).toArray(new String[l.size()]);

If your minSdkVersion is 21+ use android:buttonTint attribute to update the color of a checkbox:

<CheckBox
  ...
  android:buttonTint="@color/tint_color" />

In projects that use AppCompat library and support Android versions below 21 you can use a compat version of the buttonTint attribute:

<CheckBox
  ...
  app:buttonTint="@color/tint_color" />

In this case if you want to subclass a CheckBox don't forget to use AppCompatCheckBox instead.

PREVIOUS ANSWER:

You can change CheckBoxs drawable using android:button="@drawable/your_check_drawable" attribute.

Expanding on the previous answers even further, you can add an id attribute to your footnote's link:

 Bla bla <sup id="a1">[1](#f1)</sup>

Then from within the footnote, link back to it.

<b id="f1">1</b> Footnote content here. [?](#a1)

This will add a little ? at the end of your footnote's content, which takes your readers back to the line containing the footnote's link.

It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************  TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif

You can remove the diacritics from alphabets by using:

var str = "résumé"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, '') // returns resume

It will remove all the diacritical marks, and then perform your regex on it

@AHegde - To get the tab delimited output use separator sep='\t'.

For df.to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep='\t', mode='a')

For np.savetxt:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d', delimiter='\t')

I think this would work

 open_file1 = open("E:\\test.txt",'r')
 read_it1 = open_file1.read()
 myline1 = []
 for line1 in read_it1.splitlines():
 myline1.append(line1)
 print myline1[0]

Also check complete.cases :

> final[complete.cases(final), ]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
6 ENSG00000221312    0    1    2    3    2

na.omit is nicer for just removing all NA's. complete.cases allows partial selection by including only certain columns of the dataframe:

> final[complete.cases(final[ , 5:6]),]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
4 ENSG00000207604    0   NA   NA    1    2
6 ENSG00000221312    0    1    2    3    2

Your solution can't work. If you insist on using is.na, then you have to do something like:

> final[rowSums(is.na(final[ , 5:6])) == 0, ]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
4 ENSG00000207604    0   NA   NA    1    2
6 ENSG00000221312    0    1    2    3    2

but using complete.cases is quite a lot more clear, and faster.

<?php
ob_start();
var_dump($_POST['C']);
$result = ob_get_clean();
?>

if you want to capture the result in a variable

You could use JavaScript. Take in consideration that the big problem with doing this with JavaScript is to reset the input file. Well, this restricts to only JPG (for PDF you will have to change the mime type and the magic number):

<form id="form-id">
  <input type="file" id="input-id" accept="image/jpeg"/>
</form>

<script type="text/javascript">
    $(function(){
        $("#input-id").on('change', function(event) {
            var file = event.target.files[0];
            if(file.size>=2*1024*1024) {
                alert("JPG images of maximum 2MB");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            if(!file.type.match('image/jp.*')) {
                alert("only JPG images");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            var fileReader = new FileReader();
            fileReader.onload = function(e) {
                var int32View = new Uint8Array(e.target.result);
                //verify the magic number

I had this problem, which seemed to be caused by something broken in the solution level packages folder. I deleted the contents of the folder and let nuget install all the packages again.

I could then install new packages again.

Dictionary does not define order of items. If you just need an item use Keys or Values properties of dictionary to pick one.

Try

sdiff file1 file2

It ususally works much better in most cases for me. You may want to sort files prior, if order of lines is not important (e.g. some text config files).

For example,

sdiff -w 185 file1.cfg file2.cfg

ApplicationContextAware Interface ,the current application context, through which you can invoke the spring container services. We can get current applicationContext instance injected by below method in the class

public void setApplicationContext(ApplicationContext context) throws BeansException.

Your Problem were the slice declarations in your data structs (except for Track, they shouldn't be slices...). This was compounded by some rather goofy fieldnames in the fetched json file, which can be fixed via structtags, see godoc.

The code below parsed the json successfully. If you've further questions, let me know.

package main

import "fmt"
import "net/http"

type Tracks struct {
    Toptracks Toptracks_info
}

}

type Track_info struct {
    Name       string
    Duration   string
    Listeners  string
    Mbid       string
    Url        string
    Streamable Streamable_info

It works the same way for axes: parse(text='70^o*N') will raise the o as a superscript (the *N is to make sure the N doesn't get raised too).

labelsX=parse(text=paste(abs(seq(-100, -50, 10)), "^o ", "*W", sep=""))
labelsY=parse(text=paste(seq(50,100,10), "^o ", "*N", sep=""))
plot(-100:-50, 50:100, type="n", xlab="", ylab="", axes=FALSE)
axis(1, seq(-100, -50, 10), labels=labelsX)
axis(2, seq(50, 100, 10), labels=labelsY)
box()

Try this:

body {
  background-image:url(img/background.jpg);
  background-repeat: no-repeat;
  min-height: 679px;
  background-size: cover;
}

try this code

I was the same problem and as Pengyy suggest, that is the fix. Thanks a lot.

My problem on the Browser Console:

PortafolioComponent.html:3 ERROR Error: Error trying to diff '[object Object]'. Only arrays and iterables are allowed(…)

In my case my code fix was:

//productos.service.ts
import { Injectable } from '@angular/core';
import { Http } from '@angular/http';

@Injectable()
export class ProductosService {

  productos:any[] = [];
  cargando:boolean = true;

  constructor( private http:Http) {
    this.cargar_productos();
  }

  public cargar_productos(){

    this.cargando = true;

    this.http.get('https://webpage-88888a1.firebaseio.com/productos.json')
      .subscribe( res => {
        console.log(res.json());
        this.cargando = false;
        this.productos = res.json().productos; // Before this.productos = res.json(); 
      });
  }

}

Got the solution and it's working fine. Set the environment variables as:

• CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59 (path where your Apache Tomcat is)
• JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25; (path where your JDK is)
• JRE_Home=C:\Program Files\Java\jre1.8.0_25; (path where your JRE is)
• CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib

Late answer, but I just came on this list today!

CREATE TABLE assignment_20101120 AS SELECT * FROM assignment;

Does the same.

You want to create an empty list, then append the created list to it. This will give you the list of lists. Example:

>>> l = []
>>> l.append([1,2,3])
>>> l.append([4,5,6])
>>> l
[[1, 2, 3], [4, 5, 6]]

For those using Python-3

Using traceback module and exception.__traceback__ one can extract the stack-trace as follows:

• grab the current stack-trace using traceback.extract_stack()
• remove the last three elements (as those are entries in the stack that got me to my debug function)
• append the __traceback__ from the exception object using traceback.extract_tb()
• format the whole thing using traceback.format_list()

import traceback
def exception_to_string(excp):
   stack = traceback.extract_stack()[:-3] + traceback.extract_tb(excp.__traceback__)  # add limit=?? 
   pretty = traceback.format_list(stack)
   return ''.join(pretty) + '\n  {} {}'.format(excp.__class__,excp)

A simple demonstration:

def foo():
    try:
        something_invalid()
    except Exception as e:
        print(exception_to_string(e))

def bar():
    return foo()

We get the following output when we call bar():

  File "./test.py", line 57, in <module>
    bar()
  File "./test.py", line 55, in bar
    return foo()
  File "./test.py", line 50, in foo
    something_invalid()

  <class 'NameError'> name 'something_invalid' is not defined

It can be done with LinearLayout (less overhead and more control than the Relative Layout option). Give the second view the remaining space so gravity can work. Tested back to API 16.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Aligned left" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="end"
        android:text="Aligned right" />
</LinearLayout> 

If you want to limit the size of the first text view, do this:

Adjust weights as required. Relative layout won't allow you to set a percentage weight like this, only a fixed dp of one of the views

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Aligned left but too long and would squash the other view" />

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:gravity="end"
        android:text="Aligned right" />
</LinearLayout>

From my point of view the best way to manage multiple conditional props is the props object approach from @brigand. But it can be improved in order to avoid adding one if block for each conditional prop.

The ifVal helper

rename it as you like (iv, condVal, cv, _, ...)

You can define a helper function to return a value, or another, if a condition is met:

// components-helpers.js
export const ifVal = (cond, trueValue=true, falseValue=null) => {
  return cond ? trueValue : falseValue
}

If cond is true (or truthy), the trueValue is returned - or true. If cond is false (or falsy), the falseValue is returned - or null.

These defaults (true and null) are, usually the right values to allow a prop to be passed or not to a React component. You can think to this function as an "improved React ternary operator". Please improve it if you need more control over the returned values.

Let's use it with many props.

Build the (complex) props object

// your-code.js
import { ifVal } from './components-helpers.js'

// BE SURE to replace all true/false with a real condition in you code
// this is just an example

const inputProps = {
  value: 'foo',
  enabled: ifVal(true), // true
  noProp: ifVal(false), // null - ignored by React
  aProp: ifVal(true, 'my value'), // 'my value'
  bProp: ifVal(false, 'the true text', 'the false text') // 'my false value',
  onAction: ifVal(isGuest, handleGuest, handleUser) // it depends on isGuest value
};

 <MyComponent {...inputProps} />

This approach is something similar to the popular way to conditionally manage classes using the classnames utility, but adapted to props.

Why you should use this approach

You'll have a clean and readable syntax, even with many conditional props: every new prop just add a line of code inside the object declaration.

In this way you replace the syntax noise of repeated operators (..., &&, ? :, ...), that can be very annoying when you have many props, with a plain function call.

Our top priority, as developers, is to write the most obvious code that solve a problem. Too many times we solve problems for our ego, adding complexity where it's not required. Our code should be straightforward, for us today, for us tomorrow and for our mates.

just because we can do something doesn't mean we should

I hope this late reply will help.

For completeness:

Along the lines of Chase's answer, I usually use as.data.frame to coerce the matrix to a data.frame:

m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))

EDIT: speed test data.frame vs. as.data.frame

system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  8.005   0.108   8.165 

system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  3.759   0.048   3.802 

Yes, it appears to be faster (by about 2 times).

That way you haven't installed pip, you installed just the easy_install i.e. setuptools.

First you should remove all the packages you installed with easy_install using (see uninstall):

easy_install -m PackageName

This includes pip if you installed it using easy_install pip.

After this you remove the setuptools following the instructions from here:

If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:

setuptools-*.egg

If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:

pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

Reset (Clear) Form throught Javascript & jQuery:

Example Javascript:

document.getElementById("client").reset();

Example jQuery:

You may try using trigger() Reference Link

$('#client.frm').trigger("reset");

Using Javascript, you can easily create a drop_bad.js script to drop your database:

create drop_bad.js:

use bad;
db.dropDatabase();

Than run 1 command in terminal to exectue the script using mongo shell:

mongo < drop_bad.js

If you don't want use js, I think, you can use <a href="javascript:void(0);"></a> instead of img and then use css like

a {
  background: url('oldImage.png');
}
a:visited {
  background: url('newImage.png');
}

EDIT: Nope. Sorry it works only for :hover

You can try this for DataGrid:

DataGridCell cellToFocus = (DataGridCell)cellInfo.Column.GetCellContent(cellInfo.Item).Parent;
ViewControlHelper.SetFocus(cellToFocus, e);

use driver.findElement(By.partialLinkText("long")).click();

There is no function exit equivalent to php die() in JS, if you are not using any function then you can simply use return;

return;

As long as the web service methods and underlying exposed classes do not change, it's fairly trivial. With Visual Studio 2005 (and newer), adding a web reference creates an app.config (or web.config, for web apps) section that has this URL. All you have to do is edit the app.config file to reflect the desired URL.

In our project, our simple approach was to just have the app.config entries commented per environment type (development, testing, production). So we just uncomment the entry for the desired environment type. No special coding needed there.

I have a similar (but more complex scenario). I have a dialog, which contains a ViewPager.
One of the child pages is short, with a static height.
Another child page should always be as tall as possible.
Another child page contains a ScrollView, and the page (and thus the entire dialog) should WRAP_CONTENT if the ScrollView contents don't need the full height available to the dialog.

None of the existing answers worked completely for this specific scenario. Hold on- it's a bumpy ride.

void setupView() {
    final ViewPager.SimpleOnPageChangeListener pageChangeListener = new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            currentPagePosition = position;

            // Update the viewPager height for the current view

             */
            int decorHeight = 0;
            for (int i = 0; i < viewPager.getChildCount(); i++) {
                View child = viewPager.getChildAt(i);
                ViewPager.LayoutParams lp = (ViewPager.LayoutParams) child.getLayoutParams();
                if (lp != null && lp.isDecor) {
                    int vgrav = lp.gravity & Gravity.VERTICAL_GRAVITY_MASK;
                    boolean consumeVertical = vgrav == Gravity.TOP || vgrav == Gravity.BOTTOM;
                    if (consumeVertical) {

Much thanks to @Raanan for the code to measure views and measure the decor height. I ran into problems with his library- the animation stuttered, and I think my ScrollView wouldn't scroll when the height of the dialog was short enough to require it.

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

I got the same problem, the height of my menu bar provided by bootstrap was too big, actually i downloaded some wrong bootstrap, finally get rid of it by downloading the orignal bootstrap from this site.. http://getbootstrap.com/2.3.2/ want to use bootstrap in yii( netbeans) follow this tutorial, https://www.youtube.com/watch?v=XH_qG8gphaw... The voice is not present but the steps are slow you can easily understand and implement them. Thanks

Now use np.array_equal. From documentation:

np.array_equal([1, 2], [1, 2])
True
np.array_equal(np.array([1, 2]), np.array([1, 2]))
True
np.array_equal([1, 2], [1, 2, 3])
False
np.array_equal([1, 2], [1, 4])
False

Edit: A new toString function has been introduced in Swift 1.2 (Xcode 6.3).

You can now print the demangled type of any type using .self and any instance using .dynamicType:

struct Box<T> {}

toString("foo".dynamicType)            // Swift.String
toString([1, 23, 456].dynamicType)     // Swift.Array<Swift.Int>
toString((7 as NSNumber).dynamicType)  // __NSCFNumber

toString((Bool?).self)                 // Swift.Optional<Swift.Bool>
toString(Box<SinkOf<Character>>.self)  // __lldb_expr_1.Box<Swift.SinkOf<Swift.Character>>
toString(NSStream.self)                // NSStream

Try calling YourClass.self and yourObject.dynamicType.

I know this is 2 year old question but as every body faces a problem to round off the values at some point of time.I would like to share a different way which can give us rounded values to any scale by using BigDecimal class .Here we can avoid extra steps which are required to get the final value if we use DecimalFormat("0.00") or using Math.round(a * 100) / 100 .

import java.math.BigDecimal;

public class RoundingNumbers {
    public static void main(String args[]){
        double number = 123.13698;
        int decimalsToConsider = 2;
        BigDecimal bigDecimal = new BigDecimal(number);
        BigDecimal roundedWithScale = bigDecimal.setScale(2, BigDecimal.ROUND_HALF_UP);
        System.out.println("Rounded value with setting scale = "+roundedWithScale);

        bigDecimal = new BigDecimal(number);
        BigDecimal roundedValueWithDivideLogic = bigDecimal.divide(BigDecimal.ONE,decimalsToConsider,BigDecimal.ROUND_HALF_UP);
        System.out.println("Rounded value with Dividing by one = "+roundedValueWithDivideLogic);

    }
}

This program would give us below output

Rounded value with setting scale = 123.14
Rounded value with Dividing by one = 123.14

Stack memory is specifically the range of memory that is accessible via the Stack register of the CPU. The Stack was used as a way to implement the "Jump-Subroutine"-"Return" code pattern in assembly language, and also as a means to implement hardware-level interrupt handling. For instance, during an interrupt, the Stack was used to store various CPU registers, including Status (which indicates the results of an operation) and Program Counter (where was the CPU in the program when the interrupt occurred).

Stack memory is very much the consequence of usual CPU design. The speed of its allocation/deallocation is fast because it is strictly a last-in/first-out design. It is a simple matter of a move operation and a decrement/increment operation on the Stack register.

Heap memory was simply the memory that was left over after the program was loaded and the Stack memory was allocated. It may (or may not) include global variable space (it's a matter of convention).

Modern pre-emptive multitasking OS's with virtual memory and memory-mapped devices make the actual situation more complicated, but that's Stack vs Heap in a nutshell.

to access data in a stdClass in similar fashion you do with an asociative array just use the {$var} syntax.

$myObj = new stdClass;
$myObj->Prop1 = "Something";
$myObj->Prop2 = "Something else";

// then to acces it directly

echo $myObj->{'Prop1'};
echo $myObj->{'Prop2'};

// or what you may want

echo $myObj->{$myStringVar};

You need to configure the war plugin:

<project>
  ...
  <build>
    <plugins>
      <plugin>

        <artifactId>maven-war-plugin</artifactId>
        <version>2.3</version>
        <configuration>
          <warName>bird.war</warName>
        </configuration>
      </plugin>
    </plugins>
  </build>
  ...
</project>

Similar to Mike's and clacke's answers, here is the python one-liner (using python >= 2.5) to get the build version from a pom.xml file that gets around the fact that pom.xml files don't normally have a dtd or default namespace, so don't appear well-formed to libxml:

python -c "import xml.etree.ElementTree as ET; \
  print(ET.parse(open('pom.xml')).getroot().find('\
  {http://maven.apache.org/POM/4.0.0}version').text)"

Tested on Mac and Linux, and doesn't require any extra packages to be installed.

@Kwang-Chun Kang Thanks Kang a lot! I found the solution is working and very helpful, it really save my day. For me I am trying to create a React.js component that convert *.xlsx to json object when user upload the excel file to a html input tag. First I need to install XLSX package with:

npm install xlsx --save

Then in my component code, import with:

import XLSX from 'xlsx'

The component UI should look like this:

<input
  accept=".xlsx"
  type="file"
  onChange={this.fileReader}
/>

It calls a function fileReader(), which is exactly same as the solution provided. To learn more about fileReader API, I found this blog to be helpful: https://blog.teamtreehouse.com/reading-files-using-the-html5-filereader-api

Go and multiline strings

Using back ticks you can have multiline strings:

package main

import "fmt"

func main() {

    message := `This is a 
Multi-line Text String
Because it uses the raw-string back ticks 
instead of quotes.
`

    fmt.Printf("%s", message)
}

Instead of using either the double quote (“) or single quote symbols (‘), instead use back-ticks to define the start and end of the string. You can then wrap it across lines.

If you indent the string though, remember that the white space will count.

Please check the playground and do experiments with it.

Try

numbers = range(10, 16)
indices = (1, 1, 2, 1, 5)

result = [numbers[i] for i in indices]

Just use the Json.NET library. It lets you parse Json format strings very easily:

JObject o = JObject.Parse(@"
{
    ""something"":""value"",
    ""jagged"":
    {
        ""someother"":""value2""
    }
}");

string something = (string)o["something"];

I'd like to centralize the creation of the error response in this way:

app.get('/test', function(req, res){
  throw {status: 500, message: 'detailed message'};
});

app.use(function (err, req, res, next) {
  res.status(err.status || 500).json({status: err.status, message: err.message})
});

So I have always the same error output format.

PS: of course you could create an object to extend the standard error like this:

const AppError = require('./lib/app-error');
app.get('/test', function(req, res){
  throw new AppError('Detail Message', 500)
});

'use strict';

module.exports = function AppError(message, httpStatus) {
  Error.captureStackTrace(this, this.constructor);
  this.name = this.constructor.name;
  this.message = message;
  this.status = httpStatus;
};

require('util').inherits(module.exports, Error);

In SQL Server Management Studio 2016, perform the following:

• Right click on database

• Click delete

• Check close existing connections

• Perform delete operation

string apppath = 
    (new System.IO.FileInfo
    (System.Reflection.Assembly.GetExecutingAssembly().CodeBase)).DirectoryName;

I had the same issue, and it appears Gidon's answer has one tiny flaw: it generates a relative URL, which cannot be sent by mail.

My solution looks like this:

string link = HttpContext.Request.Url.Scheme + "://" + HttpContext.Request.Url.Authority + Url.Action("ResetPassword", "Account", new { key = randomString });

This way, a full URL is generated, and it works even if the application is several levels deep on the hosting server, and uses a port other than 80.

EDIT: I found this useful as well.

Start a timer in the constructor of your class. The interval is in milliseconds so 5*60 seconds = 300 seconds = 300000 milliseconds.

static void Main(string[] args)
{
    System.Timers.Timer timer = new System.Timers.Timer();
    timer.Interval = 300000;
    timer.Elapsed += timer_Elapsed;
    timer.Start();
}

Then call GetData() in the timer_Elapsed event like this:

static void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    //YourCode
}

For Python 3.7, I copied and changed the very nice answer by user297171 so it works in all scenarios in Python 3.7 that I tested.

    while keep_going:
        print('still going...')

do_stuff()

HEAD^^^ is the same as HEAD~3, selecting the third commit before HEAD

HEAD^2 specifies the second head in a merge commit

Take a look on pprint, The pprint module provides a capability to “pretty-print” arbitrary Python data structures in a form which can be used as input to the interpreter. If the formatted structures include objects which are not fundamental Python types, the representation may not be loadable. This may be the case if objects such as files, sockets or classes are included, as well as many other objects which are not representable as Python literals.

>>> import pprint
>>> stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni']
>>> stuff.insert(0, stuff[:])
>>> pp = pprint.PrettyPrinter(indent=4)
>>> pp.pprint(stuff)
[   ['spam', 'eggs', 'lumberjack', 'knights', 'ni'],
    'spam',
    'eggs',
    'lumberjack',
    'knights',
    'ni']
>>> pp = pprint.PrettyPrinter(width=41, compact=True)
>>> pp.pprint(stuff)
[['spam', 'eggs', 'lumberjack',
  'knights', 'ni'],
 'spam', 'eggs', 'lumberjack', 'knights',
 'ni']
>>> tup = ('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead',
... ('parrot', ('fresh fruit',))))))))
>>> pp = pprint.PrettyPrinter(depth=6)
>>> pp.pprint(tup)
('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead', (...)))))))

CHANGED to

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

Bootstrap 4

Would casting it to int help you? Money is meant to have the decimal places...

DECLARE @test AS money
SET @test = 3
SELECT CAST(@test AS int), @test

The function you want is Math.Pow in System.Math.

import tkinter as tk
...
x = tk.Label(text='Hello', visible=True)
def visiblelabel(lb, visible):
    lb.config(visible=visible)
visiblelabel(x, False)  # Hide
visiblelabel(x, True)  # Show

P.S. config can change any attribute:

x.config(text='Hello')  # Text: Hello
x.config(text='Bye', font=('Arial', 20, 'bold'))  # Text: Bye, Font: Arial Bold 20
x.config(bg='red', fg='white')  # Background: red, Foreground: white

It's a bypass of StringVar, IntVar etc.

If you want to remove CSS transitions, transformations and animations from the current webpage you can just execute this little script I wrote (inside your browsers console):

let filePath = "https://dl.dropboxusercontent.com/s/ep1nzckmvgjq7jr/remove_transitions_from_page.css";
let html = `<link rel="stylesheet" type="text/css" href="${filePath}">`;
document.querySelector("html > head").insertAdjacentHTML("beforeend", html);

It uses vanillaJS to load this css-file. Heres also a github repo in case you want to use this in the context of a scraper (Ruby-Selenium): remove-CSS-animations-repo

#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-

    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

What worked for me:

• Open my.ini with Notepad++
• Encoding --> convert to ANSI
• save

i solved this by http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/ just uncomment or add this:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

to your .htaccess file

There are several ways:

Instantiating the array:

var arr;

arr = new Array(); // empty array

// ---

arr = [];          // empty array

// ---

arr = new Array(3);
alert(arr.length);  // 3
alert(arr[0]); // undefined

// ---

arr = [3];
alert(arr.length);  // 1
alert(arr[0]); // 3

Pushing to the array:

arr = [3];     // arr == [3]
arr[1] = 4;    // arr == [3, 4]
arr[2] = 5;    // arr == [3, 4, 5]
arr[4] = 7;    // arr == [3, 4, 5, undefined, 7]

// ---

arr = [3];
arr.push(4);        // arr == [3, 4]
arr.push(5);        // arr == [3, 4, 5]
arr.push(6, 7, 8);  // arr == [3, 4, 5, 6, 7, 8]

Using .push() is the better way to add to an array, since you don't need to know how many items are already there, and you can add many items in one function call.

First off, thanks to @paper1337 for pointing me to the right resources...I'm not registered so I can't vote him up, please do so if anybody else reads this.

Here's how to accomplish what I was trying to do.

Validatable class:

public class ValidateMe : IValidatableObject
{
    [Required]
    public bool Enable { get; set; }

    [Range(1, 5)]
    public int Prop1 { get; set; }

    [Range(1, 5)]
    public int Prop2 { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        var results = new List<ValidationResult>();
        if (this.Enable)
        {
            Validator.TryValidateProperty(this.Prop1,
                new ValidationContext(this, null, null) { MemberName = "Prop1" },
                results);
            Validator.TryValidateProperty(this.Prop2,
                new ValidationContext(this, null, null) { MemberName = "Prop2" },
                results);

            // some other random test
            if (this.Prop1 > this.Prop2)
            {
                results.Add(new ValidationResult("Prop1 must be larger than Prop2"));
            }
        }
        return results;
    }
}

Using Validator.TryValidateProperty() will add to the results collection if there are failed validations. If there is not a failed validation then nothing will be add to the result collection which is an indication of success.

Doing the validation:

    public void DoValidation()
    {
        var toValidate = new ValidateMe()
        {
            Enable = true,
            Prop1 = 1,
            Prop2 = 2
        };

        bool validateAllProperties = false;

        var results = new List<ValidationResult>();

        bool isValid = Validator.TryValidateObject(
            toValidate,
            new ValidationContext(toValidate, null, null),
            results,
            validateAllProperties);
    }

It is important to set validateAllProperties to false for this method to work. When validateAllProperties is false only properties with a [Required] attribute are checked. This allows the IValidatableObject.Validate() method handle the conditional validations.

The php.js project has JavaScript implementations of many of PHP's functions. base64_encode and base64_decode are included.

You could try awk

echo "word1 word2" | awk '{ print $1 }'

With awk it is really easy to pick any word you like ($1, $2, ...)

An extremely important consideration in the choice of Expression vs Func is that IQueryable providers like LINQ to Entities can 'digest' what you pass in an Expression, but will ignore what you pass in a Func. I have two blog posts on the subject:

Simplest Way for reading bytes from file

import java.io.*;

class ReadBytesFromFile {
    public static void main(String args[]) throws Exception {
        // getBytes from anyWhere
        // I'm getting byte array from File
        File file = null;
        FileInputStream fileStream = new FileInputStream(file = new File("ByteArrayInputStreamClass.java"));

        // Instantiate array
        byte[] arr = new byte[(int) file.length()];

        // read All bytes of File stream
        fileStream.read(arr, 0, arr.length);

        for (int X : arr) {
            System.out.print((char) X);
        }
    }
}

IntelliJ has no option to click on a file and choose "Add to .gitignore" like Eclipse has.

The quickest way to add a file or folder to .gitignore without typos is:

1. Right-click on the file in the project browser and choose "Copy Path" (or use the keyboard shortcut that is displayed there).
2. Open the .gitignore file in your project, and paste.
3. Adjust the pasted line so that it is relative to the location of the .gitignore file.

Additional info: There is a .ignore plugin available for IntelliJ which adds a "Add to .gitignore" item to the popup menu when you right-click a file. It works like a charm.

For my use case, none of the previous answers worked because I was writing a server-side unit test which was failing due the following error message as described in the Unable to Mock Glassfish Jersey Client Response Object question:

java.lang.IllegalStateException: Method not supported on an outbound message.
at org.glassfish.jersey.message.internal.OutboundJaxrsResponse.readEntity(OutboundJaxrsResponse.java:145)
at ...

This exception occurred on the following line of code:

String actJsonBody = actResponse.readEntity(String.class);

The fix was to turn the problem line of code into:

String actJsonBody = (String) actResponse.getEntity();

David Heffernan explained the issue in his answer, and I wrote the improved code. See below.

A generic function

We can write a useful variadic function to concatenate any number of strings:

#include <stdlib.h>       // calloc
#include <stdarg.h>       // va_*
#include <string.h>       // strlen, strcpy

char* concat(int count, ...)
{
    va_list ap;
    int i;

    // Find required length to store merged string
    int len = 1; // room for NULL
    va_start(ap, count);
    for(i=0 ; i<count ; i++)
        len += strlen(va_arg(ap, char*));
    va_end(ap);

    // Allocate memory to concat strings
    char *merged = calloc(sizeof(char),len);
    int null_pos = 0;

    // Actually concatenate strings
    va_start(ap, count);
    for(i=0 ; i<count ; i++)
    {
        char *s = va_arg(ap, char*);
        strcpy(merged+null_pos, s);
        null_pos += strlen(s);
    }
    va_end(ap);

    return merged;
}

Usage

#include <stdio.h>        // printf

void println(char *line)
{
    printf("%s\n", line);
}

int main(int argc, char* argv[])
{
    char *str;

    str = concat(0);             println(str); free(str);
    str = concat(1,"a");         println(str); free(str);
    str = concat(2,"a","b");     println(str); free(str);
    str = concat(3,"a","b","c"); println(str); free(str);

    return 0;
}

Output:

  // Empty line
a
ab
abc

Clean-up

Note that you should free up the allocated memory when it becomes unneeded to avoid memory leaks:

char *str = concat(2,"a","b");
println(str);
free(str);

MySQL version: 5.5.28-0ubuntu0.12.04.2-log

I was also under the impression that JOIN is always better than a sub-query in MySQL, but EXPLAIN is a better way to make a judgment. Here is an example where sub queries work better than JOINs.

Here is my query with 3 sub-queries:

EXPLAIN SELECT vrl.list_id,vrl.ontology_id,vrl.position,l.name AS list_name, vrlih.position AS previous_position, vrl.moved_date 
FROM `vote-ranked-listory` vrl 
INNER JOIN lists l ON l.list_id = vrl.list_id 
INNER JOIN `vote-ranked-list-item-history` vrlih ON vrl.list_id = vrlih.list_id AND vrl.ontology_id=vrlih.ontology_id AND vrlih.type='PREVIOUS_POSITION' 
INNER JOIN list_burial_state lbs ON lbs.list_id = vrl.list_id AND lbs.burial_score < 0.5 
WHERE vrl.position <= 15 AND l.status='ACTIVE' AND l.is_public=1 AND vrl.ontology_id < 1000000000 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=43) IS NULL 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=55) IS NULL 
 AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL 
ORDER BY vrl.moved_date DESC LIMIT 200;

EXPLAIN shows:

A comparison of the rows column tells the difference and the query with JOINs is using Using temporary; Using filesort.

Of course when I run both the queries, the first one is done in 0.02 secs, the second one does not complete even after 1 min, so EXPLAIN explained these queries properly.

If I do not have the INNER JOIN on the list_tag table i.e. if I remove

AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL  

from the first query and correspondingly:

INNER JOIN list_tag lt3 ON lt3.list_id = vrl.list_id AND lt3.tag_id = 246403

from the second query, then EXPLAIN returns the same number of rows for both queries and both these queries run equally fast.

Starting from Java 7 you can use deleteIfExists that returns a boolean (or throw an Exception) depending on whether a file was deleted or not. This method may not be atomic with respect to other file system operations. Moreover if a file is in use by JVM/other program then on some operating system it will not be able to remove it. Every file can be converted to path via toPath method . E.g.

File file = ...;
boolean result = Files.deleteIfExists(file.toPath()); //surround it in try catch block

@echo off
echo Press any key to exit . . .
pause>nul

In the beginning, a compiler was responsible for turning a high-level language (defined as higher level than assembler) into object code (machine instructions), which would then be linked (by a linker) into an executable.

At one point in the evolution of languages, compilers would compile a high-level language into pseudo-code, which would then be interpreted (by an interpreter) to run your program. This eliminated the object code and executables, and allowed these languages to be portable to multiple operating systems and hardware platforms. Pascal (which compiled to P-Code) was one of the first; Java and C# are more recent examples. Eventually the term P-Code was replaced with bytecode, since most of the pseudo-operations are a byte long.

A Just-In-Time (JIT) compiler is a feature of the run-time interpreter, that instead of interpreting bytecode every time a method is invoked, will compile the bytecode into the machine code instructions of the running machine, and then invoke this object code instead. Ideally the efficiency of running object code will overcome the inefficiency of recompiling the program every time it runs.

In my opinion the answer is wrong! He asked for event.preventDefault(); when you simply return false; it calls event.preventDefault(); AND event.stopPropagation(); as well!

You can solve it by this:

<a href="#" onclick="callmymethod(event, 24)">Call</a>

function callmymethod(e, myVal){
    //doing custom things with myVal

    //here I want to prevent default
    e = e || window.event;
    e.preventDefault();
}

You can execute your task in a different thread. threading.Timer will let you execute a given callback once after some time has elapsed, if you want to execute your task, for example, as long as the callback returns True (this is actually what glib.timeout_add provides, but you might not have it installed in windows) or until you cancel it, you can use this code:

import logging, threading, functools
import time

logging.basicConfig(level=logging.NOTSET,
                    format='%(threadName)s %(message)s')

class PeriodicTimer(object):
    def __init__(self, interval, callback):
        self.interval = interval

        @functools.wraps(callback)
        def wrapper(*args, **kwargs):
            result = callback(*args, **kwargs)
            if result:
                self.thread = threading.Timer(self.interval,
                                              self.callback)
                self.thread.start()

        self.callback = wrapper

    def start(self):
        self.thread = threading.Timer(self.interval, self.callback)
        self.thread.start()

    def cancel(self):
        self.thread.cancel()


def foo():
    logging.info('Doing some work...')
    return True

timer = PeriodicTimer(1, foo)
timer.start()

for i in range(2):
    time.sleep(2)
    logging.info('Doing some other work...')

timer.cancel()

Example output:

Thread-1 Doing some work...
Thread-2 Doing some work...
MainThread Doing some other work...
Thread-3 Doing some work...
Thread-4 Doing some work...
MainThread Doing some other work...

Note: The callback isn't executed every interval execution. Interval is the time the thread waits between the callback finished the last time and the next time is called.

I would not put the key in the url, as it does violate this loose 'standard' that is REST. However, if you did, I would place it in the 'user' portion of the url.

eg: http://[email protected]/myresource/myid

This way it can also be passed as headers with basic-auth.

I have created a library for this that implements some nice features. Code can be found on GitHub: https://github.com/dazinator/Dazinator.Extensions.DependencyInjection NuGet: https://www.nuget.org/packages/Dazinator.Extensions.DependencyInjection/

Usage is straightforward:

1. Add the Dazinator.Extensions.DependencyInjection nuget package to your project.
2. Add your Named Service registrations.

    var services = new ServiceCollection();
    services.AddNamed<AnimalService>(names =>
    {
        names.AddSingleton("A"); // will resolve to a singleton instance of AnimalService
        names.AddSingleton<BearService>("B"); // will resolve to a singleton instance of BearService (which derives from AnimalService)
        names.AddSingleton("C", new BearService()); will resolve to singleton instance provided yourself.
        names.AddSingleton("D", new DisposableTigerService(), registrationOwnsInstance = true); // will resolve to singleton instance provided yourself, but will be disposed for you (if it implements IDisposable) when this registry is disposed (also a singleton).

        names.AddTransient("E"); // new AnimalService() every time..
        names.AddTransient<LionService>("F"); // new LionService() every time..

        names.AddScoped("G");  // scoped AnimalService
        names.AddScoped<DisposableTigerService>("H");  scoped DisposableTigerService and as it implements IDisposable, will be disposed of when scope is disposed of.

    });

In the example above, notice that for each named registration, you are also specifying the lifetime or Singleton, Scoped, or Transient.

You can resolve services in one of two ways, depending on if you are comfortable with having your services take a dependency on this package of not:

public MyController(Func<string, AnimalService> namedServices)
{
   AnimalService serviceA = namedServices("A");
   AnimalService serviceB = namedServices("B"); // BearService derives from AnimalService
}

or

public MyController(NamedServiceResolver<AnimalService> namedServices)
{
   AnimalService serviceA = namedServices["A"];
   AnimalService serviceB = namedServices["B"]; // instance of BearService returned derives from AnimalService
}

I have specifically designed this library to work well with Microsoft.Extensions.DependencyInjection - for example:

1. When you register named services, any types that you register can have constructors with parameters - they will be satisfied via DI, in the same way that AddTransient<>, AddScoped<> and AddSingleton<> methods work ordinarily.

2. For transient and scoped named services, the registry builds an ObjectFactory so that it can activate new instances of the type very quickly when needed. This is much faster than other approaches and is in line with how Microsoft.Extensions.DependencyInjection does things.

X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);

store.Open(OpenFlags.ReadOnly);

foreach (X509Certificate2 certificate in store.Certificates){
    //TODO's
}

When you're doing it by code the trick is to call

WindowStyle = WindowStyle.None;

first and then

WindowState = WindowState.Maximized;

to get it to display over the Taskbar.

You probably want to use the assets_base_urls configuration.

framework:
    templating:
        assets_base_urls:
            http:   [http://www.website.com]
            ssl:   [https://www.website.com]

http://symfony.com/doc/current/reference/configuration/framework.html#assets

Note that the configuration is different since Symfony 2.7:

framework:
    # ...
    assets:
        base_urls:
            - 'http://cdn.example.com/'

UPDATE

The answer is now obsolete. See this answer.

maven-compiler-plugin depends on the old version of ASM which does not support Java 10 (and Java 11) yet. However, it is possible to explicitly specify the right version of ASM:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <configuration>
        <release>10</release>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm</artifactId>
            <version>6.2</version> <!-- Use newer version of ASM -->
        </dependency>
    </dependencies>
</plugin>

You can find the latest at https://search.maven.org/search?q=g:org.ow2.asm%20AND%20a:asm&core=gav

Log in as root, then run the following MySQL commands:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

This is not possible directly, because chronologically, WHERE happens before SELECT, which always is the last step in the execution chain.

You can do a sub-select and filter on it:

SELECT * FROM
(
  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
) AS inner_table
WHERE 
  MONTH_NO > UPD_DATE

Interesting bit of info moved up from the comments:

There should be no performance hit. Oracle does not need to materialize inner queries before applying outer conditions -- Oracle will consider transforming this query internally and push the predicate down into the inner query and will do so if it is cost effective. – Justin Cave

check your DB (Database permission) and give full permission

Go to DB folder-> right click properties->security->edit-> give full control & Start menu ->run->type "uac" make it down (if it high)

You can kill a (SIGTERM) a windows process that was started from Java by calling the destroy method on the Process object. You can also kill any child Processes (since Java 9).

The following code starts a batch file, waits for ten seconds then kills all sub-processes and finally kills the batch process itself.

ProcessBuilder pb = new ProcessBuilder("cmd /c my_script.bat"));
Process p = pb.start();
p.waitFor(10, TimeUnit.SECONDS);

p.descendants().forEach(ph -> {
    ph.destroy();
});

p.destroy();

The server at x3.chatforyoursite.com needs to output the following header:

Access-Control-Allow-Origin: http://www.example.com

Where http://www.example.com is your website address. You should check your settings on chatforyoursite.com to see if you can enable this - if not their technical support would probably be the best way to resolve this. However to answer your question, you need the remote site to allow your site to access AJAX responses client side.

Select multiple lines by clicking first line then holding shift and clicking last line. Then press:

CTRL+SHIFT+L

or on MAC: CMD+SHIFT+L (as per comments)

Alternatively you can select lines and go to SELECTION MENU >> SPLIT INTO LINES.

Now you can edit multiple lines, move cursors etc. for all selected lines.

Had the exact same problem and none of the answers here helped me. Till I find this thread and post

Short: win32 modules are not guaranted to install correctly with pip. Install them directly from packages provided by developpers on github. It works like a charm.

I've added a way to display the imporper behavior of the ScrollIntoView - http://jsfiddle.net/LEqjm/258/ [it should be a comment but I don't have enough reputation]

$("ul").click(function() {
    var target = document.getElementById("target");
if ($('#scrollTop').attr('checked')) {
    target.parentNode.scrollTop = target.offsetTop;    
} else {
        target.scrollIntoView(!0);
}
});

While INT_MAX is probably the safest bet, WebKit apparently uses doubles internally and thus allows very large numbers (to a certain precision). LLONG_MAX e.g. works fine (at least in 64-Bit Chromium and WebkitGTK), but will be rounded to 9223372036854776000.

(Although you should consider carefully whether you really, really need this many z indices…).

I've started a project to help people making their first GitHub pull request. You can do the hands-on tutorial to make your first PR here

The workflow is simple as

• Fork the repo in github
• Get clone url by clicking on clone repo button
• Go to terminal and run git clone <clone url you copied earlier>
• Make a branch for changes you're makeing git checkout -b branch-name
• Make necessary changes
• Commit your changes git commit
• Push your changes to your fork on GitHub git push origin branch-name
• Go to your fork on GitHub to see a Compare and pull request button
• Click on it and give necessary details

Well, getting full path is not possible but we can have a temporary path.

Try This:

It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-

JSFIDDLE

Here is the code :-

HTML:-

<input type="file" id="i_file" value=""> 
<input type="button" id="i_submit" value="Submit">
    <br>
<img src="" width="200" style="display:none;" />
        <br>
<div id="disp_tmp_path"></div>

JS:-

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));

    $("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});

Its not exactly what you were looking for, but may be it can help you somewhere.

check this fiddle , and if you want to move the overlapped div you set its position to absolute then change it's top and left values

With

echo get_cfg_var('cfg_file_path');

you can find out which php.ini has been used by this instance of php.

If you just need to print present working directory then you can follow this.

$ vim test

#!/bin/bash
pwd
:wq to save the test file.

Give execute permission:

chmod u+x test

Then execute the script by ./test then you can see the present working directory.

I would rather use the following class to generate random numbers:

byte[] random;
System.Security.Cryptography.RNGCryptoServiceProvider prov = new System.Security.Cryptography.RNGCryptoServiceProvider();
prov.GetBytes(random);

The problem in my case was that I was running the command inside a python virtual environment and it didn't had the path to /usr/local/mysql/bin though I have put it in the .bash_profile file. Just exporting the path in the virtual env worked for me.

For your info sql_config resides inside bin directory.

• Create a console app that does what you're looking for
• Use the Windows "Scheduled Tasks" functionality to have that console app executed at the time you need it to run

That's really all you need!

Update: if you want to do this inside your app, you have several options:

• in a Windows Forms app, you could tap into the Application.Idle event and check to see whether you've reached the time in the day to call your method. This method is only called when your app isn't busy with other stuff. A quick check to see if your target time has been reached shouldn't put too much stress on your app, I think...
• in a ASP.NET web app, there are methods to "simulate" sending out scheduled events - check out this CodeProject article
• and of course, you can also just simply "roll your own" in any .NET app - check out this CodeProject article for a sample implementation

Update #2: if you want to check every 60 minutes, you could create a timer that wakes up every 60 minutes and if the time is up, it calls the method.

Something like this:

using System.Timers;

const double interval60Minutes = 60 * 60 * 1000; // milliseconds to one hour

Timer checkForTime = new Timer(interval60Minutes);
checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
checkForTime.Enabled = true;

and then in your event handler:

void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
{
    if (timeIsReady())
    {
       SendEmail();
    }
}

#grad
{
    background: -webkit-linear-gradient(left,rgba(255,0,0,0),rgba(255,0,0,1)); /*Safari 5.1-6*/
    background: -o-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1)); /*Opera 11.1-12*/
    background: -moz-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1)); /*Fx 3.6-15*/
    background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1)); /*Standard*/
}

I found this in w3schools and suited my needs while I was looking for gradient and transparency. I am providing the link to refer to w3schools. Hope this helps if any one is looking for gradient and transparency.

Also I tried it in w3schools to change the opacity pasting the link for it check it

This is what worked for me

$scope.form_name.field_name.$setDirty()

Tailor this code however you like to fit your needs, you can select text? in the paragraph to be what font or style you need!:

<head>
<style>
p{ color:#ff0000;font-family: "Times New Roman", Times, serif;} 
font{color:#000fff;background:#000000;font-size:225%;}
b{color:green;}
</style>
</head>
<body>
<p>This is your <b>text. <font>Type</font></strong></b>what you like</p>
</body>

You can run the query as:

select * from person where dob between '2011-01-01' and '2011-01-31 23:59:59'

like others pointed out, if your dates are hardcoded.

On the other hand, if the date is in another table, you can add a day and subtract a second (if the dates are saved without the second/time), like:

select * from person JOIN some_table ... where dob between some_table.initial_date and (some_table.final_date + INTERVAL 1 DAY - INTERVAL 1 SECOND)

Avoid doing casts on the dob fiels (like in the accepted answer), because that can cause huge performance problems (like not being able to use an index in the dob field, assuming there is one). The execution plan may change from using index condition to using where if you make something like DATE(dob) or CAST(dob AS DATE), so be careful!

  //use fabs()
  double sum_primary_diagonal=0;
  double sum_secondary_diagonal=0;
  double difference = fabs(sum_primary_diagonal - sum_secondary_diagonal);

Try doing this using GNU sed:

sed '/CLIENTSCRIPT="foo"/a CLIENTSCRIPT2="hello"' file

if you want to substitute in-place, use

sed -i '/CLIENTSCRIPT="foo"/a CLIENTSCRIPT2="hello"' file

Output

CLIENTSCRIPT="foo"
CLIENTSCRIPT2="hello"
CLIENTFILE="bar"

I also faced the same problem.I resolved by doing the build by following steps as.

-->Right click on the project select RunAs ->Run configurations

Select your project as BaseDirectory. In place of goals give eclipse:eclipse install

-->In the second tab give -Xmx1024m as VM arguments.

Another way to do this is:

mongo mongodb://mongoDbIPorDomain:port

I had the same issue since i was tring to re produce the aspx file from a visual studio 2010 project so the controls had clientidmode="Static" property. When this is removed it was resolved.

In general use serialize() on the form element.

Please be mindful that multiple <select> options are serialized under the same key, e.g.

<select id="foo" name="foo" multiple="multiple">
    <option value="1">one</option>
    <option value="2">two</option>
    <option value="3">three</option>
</select>

will result in a query string that includes multiple occurences of the same query parameter:

[path]?foo=1&foo=2&foo=3&someotherparams...

which may not be what you want in the backend.

I use this JS code to reduce multiple parameters to a comma-separated single key (shamelessly copied from a commenter's response in a thread over at John Resig's place):

function compress(data) {
    data = data.replace(/([^&=]+=)([^&]*)(.*?)&\1([^&]*)/g, "$1$2,$4$3");
    return /([^&=]+=).*?&\1/.test(data) ? compress(data) : data;
}

which turns the above into:

[path]?foo=1,2,3&someotherparams...

In your JS code you'd call it like this:

var inputs = compress($("#your-form").serialize());

Hope that helps.

I had a similar issue. I resolved it by changing

<basicHttpBinding>

to

<basicHttpsBinding>

and also changed my URL to use https:// instead of http://.

Also in <endpoint> node, change

binding="basicHttpBinding" 

to

binding="basicHttpsBinding"

This worked.

I solved it programmatically using this code:

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(Color.parseColor("#FFFFFF"), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

Revision 1:

Starting from API 23 (Marshmallow) the drawable resource abc_ic_ab_back_mtrl_am_alpha is changed to abc_ic_ab_back_material.

Sometimes you need to have the ORDER BY in each of the sections that need to be combined with UNION.

In this case

SELECT * FROM 
(
  SELECT table1.field1 FROM table1 ORDER BY table1.field1
) DUMMY_ALIAS1

UNION ALL

SELECT * FROM
( 
  SELECT table2.field1 FROM table2 ORDER BY table2.field1
) DUMMY_ALIAS2

I had same problem when I define PATH below

C:\Program Files (x86)\Java\jre1.8.0_45\bin;C:\dev\sdk\android\platform-tools

and the problem solved when I bring adb root at first.

C:\dev\sdk\android\platform-tools;C:\Program Files (x86)\Java\jre1.8.0_45\bin

The data is stored on the device, in your application's private data area. It is not in an Eclipse project.

There is good solution for your problem - use TeXify github plugin (mentioned by Tom Hale answer - but I developed his answer in given link below) - more details about this github plugin and explanation why this is good approach you can find in that answer.

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

pkill is the easiest command line utility

pkill -f node

}

I just have the same situation as you and I have just fixed this problem.

my conf/zoo.cfg just like this:

server.1=10.194.236.32:2888:3888
server.2=10.194.236.33:2888:3888
server.3=10.208.177.15:2888:3888
server.4=10.210.154.23:2888:3888
server.5=10.210.154.22:2888:3888

then i set data/myid file content like this:

1      //at host  10.194.236.32
2      //at host  10.194.236.33

4      //at host  10.210.154.23
5      //at host  10.210.154.22

finally restart zookeeper

Your initial problem was:

class ReportView: NSView {
  var categoriesPerPage = [[Int]]()
  var numPages: Int = { return categoriesPerPage.count }
}

Instance member 'categoriesPerPage' cannot be used on type 'ReportView'

previous posts correctly point out, if you want a computed property, the = sign is errant.

Additional possibility for error:

If your intent was to "Setting a Default Property Value with a Closure or Function", you need only slightly change it as well. (Note: this example was obviously not intended to do that)

class ReportView: NSView {
  var categoriesPerPage = [[Int]]()
  var numPages: Int = { return categoriesPerPage.count }()
}

Instead of removing the =, we add () to denote a default initialization closure. (This can be useful when initializing UI code, to keep it all in one place.)

However, the exact same error occurs:

Instance member 'categoriesPerPage' cannot be used on type 'ReportView'

The problem is trying to initialize one property with the value of another. One solution is to make the initializer lazy. It will not be executed until the value is accessed.

class ReportView: NSView {
  var categoriesPerPage = [[Int]]()
  lazy var numPages: Int = { return categoriesPerPage.count }()
}

now the compiler is happy!

Have you take a look Google Maps Geolocation Api? Google Map Geolocation

This is simple RestApi, you just need POST a request, the the service will return a location with accuracy in meters.

At the time you emit the very first line,

Artist  Title   Price   Genre   Disc    Sale    Tax Cash

to achieve "alignment", you have to know "in advance" how wide each column will need to be (otherwise, alignment is impossible). Once you do know the needed width for each column (there are several possible ways to achieve that depending on where your data's coming from), then the setw function mentioned in the other answer will help, or (more brutally;-) you could emit carefully computed number of extra spaces (clunky, to be sure), etc. I don't recommend tabs anyway as you have no real control on how the final output device will render those, in general.

Back to the core issue, if you have each column's value in a vector<T> of some sort, for example, you can do a first formatting pass to determine the maximum width of the column, for example (be sure to take into account the width of the header for the column, too, of course).

If your rows are coming "one by one", and alignment is crucial, you'll have to cache or buffer the rows as they come in (in memory if they fit, otherwise on a disk file that you'll later "rewind" and re-read from the start), taking care to keep updated the vector of "maximum widths of each column" as the rows do come. You can't output anything (not even the headers!), if keeping alignment is crucial, until you've seen the very last row (unless you somehow magically have previous knowledge of the columns' widths, of course;-).

Usign fs with node.

var fs = require('fs');

try {  
    var data = fs.readFileSync('file.txt', 'utf8');
    console.log(data.toString());    
} catch(e) {
    console.log('Error:', e.stack);
}

sentence="one;two;three"

If you have two date objects, you can just subtract them, which computes a timedelta object.

from datetime import date

d0 = date(2008, 8, 18)
d1 = date(2008, 9, 26)
delta = d1 - d0
print(delta.days)

The relevant section of the docs: https://docs.python.org/library/datetime.html.

See this answer for another example.

If there is no selection, you can use the properties .selectionStart or .selectionEnd (with no selection they're equal).

var cursorPosition = $('#myTextarea').prop("selectionStart");

Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.

I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.

I do not really think so, what I can find is the word "this." causes the hibernate not to include any restrictions in its query, which means it got all the records lists. About the hibernate bug that was reported, I can see it's reported as fixed but I totally failed to download the Patch.

I hide the warnings in the pink boxes by running the following code in a cell:

from IPython.display import HTML
HTML('''<script>
code_show_err=false; 
function code_toggle_err() {
 if (code_show_err){
 $('div.output_stderr').hide();
 } else {
 $('div.output_stderr').show();
 }
 code_show_err = !code_show_err
} 
$( document ).ready(code_toggle_err);
</script>
To toggle on/off output_stderr, click <a href="javascript:code_toggle_err()">here</a>.''')

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

A very similar construction is available in the language

**if <statement>; <evaluation> {
   [statements ...]
} else {
   [statements ...]
}*

i.e.

if path,err := os.Executable(); err != nil {
   log.Println(err)
} else {
   log.Println(path)
}

1. Open SDK Manager and download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.

2. Now go to your SDK directory (C:\users\username\AppData\Local\Android\sdk, generally). In this directory, go to extras ? Intel ? Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe".

   In case you get an error like "Intel virtualization technology (vt,vt-x) is not enabled", go to your BIOS settings and enable hardware virtualization.

3. Restart Android Studio and then try to start the AVD again.

It might take a minute or 2 to show the emulator window.

You can follow this Google JavaScript Style Guide

In general, use functionNamesLikeThis, variableNamesLikeThis, ClassNamesLikeThis, EnumNamesLikeThis, methodNamesLikeThis, and SYMBOLIC_CONSTANTS_LIKE_THIS.

EDIT: See nice collection of JavaScript Style Guides And Beautifiers.

You can use the following to parse a string to an integer:

int value=Integer.parseInt(textView.getText().toString());

(1) input: 12 then it will work.. because textview has taken this 12 number as "12" string.

(2) input: "abdul" then it will throw an exception that is NumberFormatException. So to solve this we need to use try catch as I have mention below:

  int tax_amount=20;
  EditText edit=(EditText)findViewById(R.id.editText1);
     try
       {

        int value=Integer.parseInt(edit.getText().toString());
        value=value+tax_amount;
        edit.setText(String.valueOf(value));// to convert integer to string 

       }catch(NumberFormatException ee){
       Log.e(ee.toString());
       }

For Cygwin users:

Installing n (node version manager) in Cygwin doesn't work, instead update node with:

wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\pathto\nodejs\node.exe'
# Updating npm
npm i -g npm

Yes, you need to install wget first.

You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.

I've just done this in a grunt project of ours. We needed a newer version of connect, since 2.7.3. was causing trouble for us. So I created a file named npm-shrinkwrap.json:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

npm should automatically pick it up while doing the install for the project.

(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)

This one should work

<button [ngClass]="{[namespace + '-mybutton']: type === 'mybutton'}"></button>

but Angular throws on this syntax. I'd consider this a bug. See also https://stackoverflow.com/a/36024066/217408

The others are invalid. You can't use [] together with {{}}. Either one or the other. {{}} binds the result stringified which doesn't lead to the desired result in this case because an object needs to be passed to ngClass.

Plunker example

As workaround the syntax shown by @A_Sing or

<button [ngClass]="type === 'mybutton' ? namespace + '-mybutton' : ''"></button>

can be used.

I had a similar problem which was solved by going to the "SQL Server Configuration Manager" and making sure that the "SQL Server Browser" was configured to start automatically and was started.

I came across this solution in the answer of this forum post: http://social.msdn.microsoft.com/Forums/en-US/sqlexpress/thread/8cdc71eb-6929-4ae8-a5a8-c1f461bd61b4/

I hope this helps somebody out there.

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

data is a dict object. So, iterate over it like this:

Python 2

for key, value in data.iteritems():
    print key, value

Python 3

for key, value in data.items():
    print(key, value)

var divs = $("div[class*='alert-box']");

In the Hibernate 5.2 and above, you able to remove the hibernate proxy as below, it will give you the actual object so you can serialize it properly:

Object unproxiedEntity = Hibernate.unproxy( proxy );

check out this.

<activity android:name=".Calculator"
    android:windowSoftInputMode="stateHidden|adjustResize" 
    android:theme="@android:style/Theme.Black.NoTitleBar">
</activity>

use quick tip using top command in linux/unix

$ top

and then hit Shift+m (i.e. write a capital M).

From man top

SORTING of task window
  For compatibility, this top supports most of the former top sort keys.
  Since this is primarily a service to former top users, these commands do
  not appear on any help screen.
    command   sorted-field                  supported
      A         start time (non-display)      No
      M         %MEM                          Yes
      N         PID                           Yes
      P         %CPU                          Yes
      T         TIME+                         Yes

Or alternatively: hit Shift + f , then choose the display to order by memory usage by hitting key n then press Enter. You will see active process ordered by memory usage
