db.<collection>.find({}, {field1: <value>, field2: <value> ...})

In your example, you can do something like:

db.students.find({}, {"roll":true, "_id":false})

Projection

The projection parameter determines which fields are returned in the matching documents. The projection parameter takes a document of the following form:

{ field1: <value>, field2: <value> ... }

The <value> can be any of the following:

1. 1 or true to include the field in the return documents.

2. 0 or false to exclude the field.

NOTE

For the _id field, you do not have to explicitly specify _id: 1 to return the _id field. The find() method always returns the _id field unless you specify _id: 0 to suppress the field.

Here I just want to add some more complex usage.

// Document 
{ 
"_id" : 1
"shapes" : [
  {"shape" : "square",  "color" : "red"},
  {"shape" : "circle",  "color" : "green"}
  ] 
} 

{ 
"_id" : 2
"shapes" : [
  {"shape" : "square",  "color" : "red"},
  {"shape" : "circle",  "color" : "green"}
  ] 
} 


// The Query   
db.contents.find({
    "_id" : ObjectId(1),
    "shapes.color":"red"
},{
    "_id": 0,
    "shapes" :{
       "$elemMatch":{
           "color" : "red"
       } 
    }
}) 


//And the Result

{"shapes":[

Can I see your User class? This is just using restrictions below. I don't see why Restrictions would be really any different than Examples (I think null fields get ignored by default in examples though).

getCurrentSession().createCriteria(User.class)
.setProjection( Projections.distinct( Projections.projectionList()
.add( Projections.property("name"), "name")
.add( Projections.property("city"), "city")))
.add( Restrictions.eq("city", "TEST")))
.setResultTransformer(Transformers.aliasToBean(User.class))
.list();

I've never used the alaistToBean, but I just read about it. You could also just loop over the results..

List<Object> rows = criteria.list();
for(Object r: rows){
  Object[] row = (Object[]) r;
  Type t = ((<Type>) row[0]);
}

If you have to you can manually populate User yourself that way.

Its sort of hard to look into the issue without some more information to diagnose the issue.

In the case of Android projects, you can fix this error by changing the project/module gradle file (build.gradle) as follows:

dependencies { implementation 'com.android.support:support-annotations:24.2.0' }

For more informations, please refer here.

Just make regular link look like button :)

<a href="#" role="button" class="btn btn-success btn-large">Click here!</a>

"role" inside a href code makes it look like button, ofc you can add more variables such as class.

This is an online database but you can try with the stackoverflow database: https://data.stackexchange.com/stackoverflow/query/new

You also can download its dumps here:

The methods viewWillLayoutSubviews and viewDidLayoutSubviews aren't mentioned in the diagrams, but these are called between viewWillAppear and viewDidAppear. They can be called multiple times.

Assume you stored that dictionary in a variable called values. To get id in to a variable, do:

idValue = values['criteria'][0]['id']

If that json is in a file, do the following to load it:

import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()

If that json is from a URL, do the following to load it:

import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()

To print ALL of the criteria, you could:

for criteria in values['criteria']:
    for key, value in criteria.iteritems():
        print key, 'is:', value
    print ''

If you know which column to search against, you can use array_search() and array_column():

$userdb = Array
(
    (0) => Array
        (
            ('uid') => '100',
            ('name') => 'Sandra Shush',
            ('url') => 'urlof100'
        ),

    (1) => Array
        (
            ('uid') => '5465',
            ('name') => 'Stefanie Mcmohn',
            ('url') => 'urlof5465'
        ),

    (2) => Array
        (
            ('uid') => '40489',
            ('name') => 'Michael',
            ('url') => 'urlof40489'
        )
);

if(array_search('urlof5465', array_column($userdb, 'url')) !== false) {
    echo 'value is in multidim array';
}
else {
    echo 'value is not in multidim array';
}

This idea is in the comments section for array_search() on the PHP manual;

The documentation for this at the MySQL site is woefully out of date and riddled with foot-guns (such as interactive_timeout). Issuing FLUSH TABLES WITH READ LOCK as part of your export of the master generally only makes sense when coordinated with a storage/filesystem snapshot such as LVM or zfs.

If you are going to use mysqldump, you should rely instead on the --master-data option to guard against human error and release the locks on the master as quickly as possible.

Assume the master is 192.168.100.50 and the slave is 192.168.100.51, each server has a distinct server-id configured, the master has binary logging on and the slave has read-only=1 in my.cnf

To stage the slave to be able to start replication just after importing the dump, issue a CHANGE MASTER command but omit the log file name and position:

slaveserver> CHANGE MASTER TO MASTER_HOST='192.168.100.50', MASTER_USER='replica', MASTER_PASSWORD='asdmk3qwdq1';

Issue the GRANT on the master for the slave to use:

masterserver> GRANT REPLICATION SLAVE ON *.* TO 'replica'@'192.168.100.51' IDENTIFIED BY 'asdmk3qwdq1';

Export the master (in screen) using compression and automatically capturing the correct binary log coordinates:

mysqldump --master-data --all-databases --flush-privileges | gzip -1 > replication.sql.gz

Copy the replication.sql.gz file to the slave and then import it with zcat to the instance of MySQL running on the slave:

zcat replication.sql.gz | mysql

Start replication by issuing the command to the slave:

slaveserver> START SLAVE;

Optionally update the /root/.my.cnf on the slave to store the same root password as the master.

If you are on 5.1+, it is best to first set the master's binlog_format to MIXED or ROW. Beware that row logged events are slow for tables which lack a primary key. This is usually better than the alternative (and default) configuration of binlog_format=statement (on master), since it is less likely to produce the wrong data on the slave.

If you must (but probably shouldn't) filter replication, do so with slave options replicate-wild-do-table=dbname.% or replicate-wild-ignore-table=badDB.% and use only binlog_format=row

This process will hold a global lock on the master for the duration of the mysqldump command but will not otherwise impact the master.

If you are tempted to use mysqldump --master-data --all-databases --single-transaction (because you only using InnoDB tables), you are perhaps better served using MySQL Enterprise Backup or the open source implementation called xtrabackup (courtesy of Percona)

[edit]

I tried to rewrite your query, but even yours will work once you associate aliases to the aggregate columns in the query that defines 'd'.

I think you are looking for the following:

First one:

select 
    c.duration, 
    c.totalbookings, 
    d.bkdqty 
from
    (select 
               month(bookingdate) as duration, 
               count(*) as totalbookings 
           from 
               entbookings
           group by month(bookingdate)
    ) AS c 
    inner join 
    (SELECT 
               duration, 
               sum(totalitems) 'bkdqty'
           FROM 
               [DrySoftBranch].[dbo].[mnthItemWiseTotalQty] ('1') AS BkdQty
           group by duration
    ) AS d 
    on c.duration = d.duration

Second one:

select 
    c.duration, 
    c.totalbookings, 
    d.bkdqty 
from
    (select 
               month(bookingdate) as duration, 
               count(*) as totalbookings 
           from 
               entbookings
           group by month(bookingdate)
    ) AS c 
    inner join 
    (select 
               month(clothdeliverydate) 'clothdeliverydatemonth', 
               SUM(CONVERT(INT, deliveredqty)) 'bkdqty'
           FROM 
               barcodetable
           where 
               month(clothdeliverydate) is not null
               group by month(clothdeliverydate)
    ) AS d 
    on c.duration = d.duration

CharsetDecoder should be what you are looking for, no ?

Many network protocols and files store their characters with a byte-oriented character set such as ISO-8859-1 (ISO-Latin-1).
However, Java's native character encoding is Unicode UTF16BE (Sixteen-bit UCS Transformation Format, big-endian byte order).

See Charset. That doesn't mean UTF16 is the default charset (i.e.: the default "mapping between sequences of sixteen-bit Unicode code units and sequences of bytes"):

Every instance of the Java virtual machine has a default charset, which may or may not be one of the standard charsets.
[US-ASCII, ISO-8859-1 a.k.a. ISO-LATIN-1, UTF-8, UTF-16BE, UTF-16LE, UTF-16]
The default charset is determined during virtual-machine startup and typically depends upon the locale and charset being used by the underlying operating system.

This example demonstrates how to convert ISO-8859-1 encoded bytes in a ByteBuffer to a string in a CharBuffer and visa versa.

// Create the encoder and decoder for ISO-8859-1
Charset charset = Charset.forName("ISO-8859-1");
CharsetDecoder decoder = charset.newDecoder();
CharsetEncoder encoder = charset.newEncoder();

try {
    // Convert a string to ISO-LATIN-1 bytes in a ByteBuffer
    // The new ByteBuffer is ready to be read.
    ByteBuffer bbuf = encoder.encode(CharBuffer.wrap("a string"));

    // Convert ISO-LATIN-1 bytes in a ByteBuffer to a character ByteBuffer and then to a string.
    // The new ByteBuffer is ready to be read.
    CharBuffer cbuf = decoder.decode(bbuf);
    String s = cbuf.toString();
} catch (CharacterCodingException e) {
}

2019 update: This is was the answer that worked for me. As I needed multiple ajax requests to fire and return data first to count the list items.

$(document).ajaxComplete(function(){
       alert("Everything is ready now!");
});

I'd use

files=(*)

And then if you need data about the file, such as size, use the stat command on each file.

DateTime.now.new_offset(0)

will work in standard Ruby (i.e. without ActiveSupport).

Virtual Earth does it. There is also a web service at geocoder.us

If you want to keep your version same like rails will be 2.3.8 and gem version will be latest. You can use this solution Latest gem with Rails2.x. in this some changes in boot.rb file and environment.rb file.

require 'thread' in boot.rb file at the top.

and in environment.rb file add the following code above the initializer block.

if Gem::Version.new(Gem::VERSION) >= Gem::Version.new('1.3.7')
 module Rails
   class GemDependency
     def requirement
       r = super
       (r == Gem::Requirement.default) ? nil : r
     end
   end
 end
end

The error is here:

hasLetter("a",words[]);

You are passing the first item of words, instead of the array.

Instead, pass the array to the function:

hasLetter("a",words);

Problem solved!

Here's a breakdown of what the problem was:

I'm guessing in your browser (chrome throws a different error), words[] == words[0], so when you call hasLetter("a",words[]);, you are actually calling hasLetter("a",words[0]);. So, in essence, you are passing the first item of words to your function, not the array as a whole.

Of course, because words is just an empty array, words[0] is undefined. Therefore, your function call is actually:

hasLetter("a", undefined);

which means that, when you try to access d[ascii], you are actually trying to access undefined[0], hence the error.

Here's a version that uses setjmp/longjmp, because someone had to do it:

#include <stdio.h>
#include <stdlib.h>
#include <setjmp.h>

void print(int i) {
    printf("%d\n", i);
}
typedef void (*func_t)(int);

int main() {
    jmp_buf buf;
    func_t f[] = {print, exit};
    int i = setjmp(buf)+1;
    f[i/1001](i);
    longjmp(buf, i);
    return 0;
}

You can do :

1) javac -cp /path/to/jar/file Myprogram.java

2) java -cp .:/path/to/jar/file Myprogram

So, lets suppose your current working directory in terminal is src/Report/

javac -cp src/external/myfile.jar Reporter.java

java -cp .:src/external/myfile.jar Reporter

You should look into Java's interfaces. A quick Google search revealed this page, which looks pretty good.

I like to think of an interface as a "promise" of sorts: Any class that implements it has certain behavior that can be expected of it, and therefore you can put an instance of an implementing class into an interface-type reference.

A simple example is the java.lang.Comparable interface. By implementing all methods in this interface in your own class, you are claiming that your objects are "comparable" to one another, and can be partially ordered.

Implementing an interface requires two steps:

1. Declaring that the interface is implemented in the class declaration
2. Providing definitions for ALL methods that are part of the interface.

Interface java.lang.Comparable has just one method in it, public int compareTo(Object other). So you need to provide that method.

Here's an example. Given this class RationalNumber:

public class RationalNumber
{
    public int numerator;
    public int denominator;

    public RationalNumber(int num, int den)
    {
        this.numerator = num;
        this.denominator = den;
    }
}

(Note: It's generally bad practice in Java to have public fields, but I am intending this to be a very simple plain-old-data type so I don't care about public fields!)

If I want to be able to compare two RationalNumber instances (for sorting purposes, maybe?), I can do that by implementing the java.lang.Comparable interface. In order to do that, two things need to be done: provide a definition for compareTo and declare that the interface is implemented.

Here's how the fleshed-out class might look:

public class RationalNumber implements java.lang.Comparable
{
    public int numerator;
    public int denominator;

    public RationalNumber(int num, int den)
    {
        this.numerator = num;
        this.denominator = den;
    }

    public int compareTo(Object other)
    {
        if (other == null || !(other instanceof RationalNumber))
        {
            return -1; // Put this object before non-RationalNumber objects
        }

        RationalNumber r = (RationalNumber)other;

        // Do the calculations by cross-multiplying. This isn't really important to
        // the answer, but the point is we're comparing the two rational numbers.
        // And no, I don't care if it's mathematically inaccurate.

        int myTotal = this.numerator * other.denominator;
        int theirTotal = other.numerator * this.denominator;

        if (myTotal < theirTotal) return -1;
        if (myTotal > theirTotal) return 1;
        return 0;
    }
}

You're probably thinking, what was the point of all this? The answer is when you look at methods like this: sorting algorithms that just expect "some kind of comparable object". (Note the requirement that all objects must implement java.lang.Comparable!) That method can take lists of ANY kind of comparable objects, be they Strings or Integers or RationalNumbers.

NOTE: I'm using practices from Java 1.4 in this answer. java.lang.Comparable is now a generic interface, but I don't have time to explain generics.

/* Provoke an error -- the BONES table does not exist */

If you have the connection string you could also use MongoDatabase directly:

var db =  MongoDatabase.Create(connectionString);
var coll = db.GetCollection("MyCollection");

How do I make Axios send cookies in requests automatically?

set axios.defaults.withCredentials = true;

or for some specific request you can use axios.get(url,{withCredentials:true})

this will give CORS error if your 'Access-Control-Allow-Origin' is set to wildcard(*). Therefore make sure to specify the url of origin of your request

for ex: if your front-end which makes the request runs on localhost:3000 , then set the response header as

res.setHeader('Access-Control-Allow-Origin', 'http://localhost:3000');

also set

res.setHeader('Access-Control-Allow-Credentials',true);

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

I prefer using the selector and I apply it on the document.

This binds itself on the document and will be applicable to the elements that will be rendered after page load.

For example:

$(document).on("click", 'selector', function() {
    // Your code here
});

That's the Unicode Replacement Character, \uFFFD. (info)

Something like this should work:

String strImport = "For some reason my ?double quotes? were lost.";
strImport = strImport.replaceAll("\uFFFD", "\"");

I had some problems with pending request for mp3 files. I had a list of mp3 files and one player to play them. If I picked a file that had already been downloaded, Chrome would block the request and show "pending request" in the network tab of the developer tools.

All versions of Chrome seem to be affected.

Here is a solution I found:

player[0].setAttribute('src','video.webm?dummy=' + Date.now());

You just add a dummy query string to the end of each url. This forces Chrome to download the file again.

Another example with popcorn player (using jquery) :

url = $(this).find('.url_song').attr('url');
pop = Popcorn.smart( "#player_",  url + '?i=' + Date.now());

This works for me. In fact, the resource is not stored in the cache system. This should also work in the same way for .csv files.

I found this question looking to change the timezone in my Django project's settings.py file to the United Kingdom.

Using the tz database in jfs' solution I found the answer:

Similar to Underscore library there is another library called as 'lodash' that has one method "orderBy" which takes in the parameter to determine in which order to sort it. You can use it like

_.orderBy('collection', 'propertyName', 'desc')

For some reason, it's not documented on the website docs.

I'd avoid eval.

To solve this problem, you should know these things about JavaScript.

1. Functions are first-class objects, so they can be properties of an object (in which case they are called methods) or even elements of arrays.
2. If you aren't choosing the object a function belongs to, it belongs to the global scope. In the browser, that means you're hanging it on the object named "window," which is where globals live.
3. Arrays and objects are intimately related. (Rumor is they might even be the result of incest!) You can often substitute using a dot . rather than square brackets [], or vice versa.

Your problem is a result of considering the dot manner of reference rather than the square bracket manner.

So, why not something like,

window["functionName"]();

That's assuming your function lives in the global space. If you've namespaced, then:

myNameSpace["functionName"]();

Avoid eval, and avoid passing a string in to setTimeout and setInterval. I write a lot of JS, and I NEVER need eval. "Needing" eval comes from not knowing the language deeply enough. You need to learn about scoping, context, and syntax. If you're ever stuck with an eval, just ask--you'll learn quickly.

If you want them gone by default, you can set:

Chart.defaults.scale.gridLines.display = false;

This is the best way I found for Proxy and not proxy users

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

I had the same error.

I am using Jboss 7.1 AS. In the configuration file - standalone.xml edit the following tag. (stop your server and edit)

The ALL has the lowest possible rank and is intended to turn on all logging.

You can use:

The Java JNI requires OS libraries of the same "bittiness" as the JVM. If you attempt to build something that depends, for example, on IESHIMS.DLL (lives in %ProgramFiles%\Internet Explorer) you need to take the 32bit version when your JVM is 32bit, the 64bit version when your JVM is 64bit. Likewise for other platforms.

Apart from that, you should be all set. The generated Java bytecode s/b the same.

Note that you should use 64bit Java compiler for larger projects because it can address more memory.

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

The substr function can return false in many special cases, so here is my version, which deals with these issues:

function startsWith( $haystack, $needle ){
  return $needle === ''.substr( $haystack, 0, strlen( $needle )); // substr's false => empty string
}

function endsWith( $haystack, $needle ){
  $len = strlen( $needle );
  return $needle === ''.substr( $haystack, -$len, $len ); // ! len=0
}

Tests (true means good):

var_dump( startsWith('',''));
var_dump( startsWith('1',''));
var_dump(!startsWith('','1'));
var_dump( startsWith('1','1'));
var_dump( startsWith('1234','12'));
var_dump(!startsWith('1234','34'));
var_dump(!startsWith('12','1234'));
var_dump(!startsWith('34','1234'));
var_dump('---');
var_dump( endsWith('',''));
var_dump( endsWith('1',''));
var_dump(!endsWith('','1'));
var_dump( endsWith('1','1'));
var_dump(!endsWith('1234','12'));
var_dump( endsWith('1234','34'));
var_dump(!endsWith('12','1234'));
var_dump(!endsWith('34','1234'));

Also, the substr_compare function also worth looking. http://www.php.net/manual/en/function.substr-compare.php

• Very large transactions, inserting/updating a lot of data and then reloading it. Basically this is down to not considering the multi-user environment the database works in.

• Overuse of functions, specifically as results in selects and in where clauses which causes the function to be called over and over again for the results. This, I think, fits under the general case of them trying to work in the procedural fashion they're more used to rather than use SQL to its full advantage.

I believe what you are looking for is "git restore".

The easiest way is to remove the file locally, and then execute the git restore command for that file:

$ rm file.txt
$ git restore file.txt 

I always do ...

myTimer.Stop();
myTimer.Start();

... is that a hack? :)

Per comment, on Threading.Timer, it's the Change method ...

dueTime Type: System.Int32 The amount of time to delay before the invoking the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout.Infinite to prevent the timer from restarting. Specify zero (0) to restart the timer immediately.

If you want to copy a one-dimensional list, use

b = a[:]

However, if a is a 2-dimensional list, this is not going to work for you. That is, any changes in a will also be reflected in b. In that case, use

b = [[a[x][y] for y in range(len(a[0]))] for x in range(len(a))]

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

Instead of using substring with a fixed index, you'd better use replace :

$("#date").html(function(t){
    return t.replace(/^([^\/]*\/)/, '<span>$1</span><br>')
});

One advantage is that it would still work if the first / is at a different position.

Another advantage of this construct is that it would be extensible to more than one elements, for example to all those implementing a class, just by changing the selector.

Demonstration (note that I had to select jQuery in the menu in the left part of jsfiddle's window)

If you want to run the script directly, you can:

1. Add the FolderA's path to the environment variable (PYTHONPATH).
2. Add the path to sys.path in the your script.

Then:

C++20 will add constexpr strings and vectors

The following proposal has been accepted apparently: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0980r0.pdf and it adds constructors such as:

// 20.3.2.2, construct/copy/destroy
constexpr
basic_string() noexcept(noexcept(Allocator())) : basic_string(Allocator()) { }
constexpr
explicit basic_string(const Allocator& a) noexcept;
constexpr
basic_string(const basic_string& str);
constexpr
basic_string(basic_string&& str) noexcept;

in addition to constexpr versions of all / most methods.

There is no support as of GCC 9.1.0, the following fails to compile:

#include <string>

int main() {
    constexpr std::string s("abc");
}

with:

g++-9 -std=c++2a main.cpp

with error:

error: the type ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} of ‘constexpr’ variable ‘s’ is not literal

std::vector discussed at: Cannot create constexpr std::vector

Tested in Ubuntu 19.04.

If you are using Jupyter in anaconda, after conda update scikit-learn in terminal, close anaconda and restart, otherwise the error will occur again.

The error arises because gnuplot is trying to interpret the word "plot" as the filename to plot, but you haven't assigned any strings to a variable named "plot" (which is good – that would be super confusing).

If you want to set it to LF as default, you can go to File->Preferences->Settings and under user settings you can paste this line in below your other user settings.

"files.eol": "\n"

For example.

"git.confirmSync": false,
"window.zoomLevel": -1,
"workbench.activityBar.visible": true,
"editor.wordWrap": true,
"workbench.iconTheme": "vscode-icons",
"window.menuBarVisibility": "default",
"vsicons.projectDetection.autoReload": true,
"files.eol": "\n"

The new pathlib library simplifies this to one line:

from pathlib import Path
result = list(Path(PATH).glob('**/*.txt'))

You can also use the generator version:

from pathlib import Path
for file in Path(PATH).glob('**/*.txt'):
    pass

This returns Path objects, which you can use for pretty much anything, or get the file name as a string by file.name.

The only mechanism to comment out Python code (understood as code ignored by the interpreter) is the #.

As you say, you can also use string literals, that are not ignored by the interpreter, but can be completely irrelevant for the program execution.

Just to add to this:

If you also need to prevent the user to manually type a date in the past, this is a possible solution. This is what we ended up doing (based on @Nicola Peluchetti's answer)

var dateToday = new Date();

$("#myDatePickerInput").change(function () {
    var updatedDate = $(this).val();
    var instance = $(this).data("datepicker");
    var date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, updatedDate, instance.settings);

    if (date < dateToday) {
        $(this).datepicker("setDate", dateToday);
    }
});

What this does is to change the value to today's date if the user manually types a date in the past.

If the transfer mode is Buffered then make sure that the values of MaxReceivedMessageSize and MaxBufferSize is same. I just resolved the faulted state issue this way after grappling with it for hours and thought i'll post it here if it helps someone.

I had the same problem but it had nothing to do with annotations. The problem happened while indexing beans in my container (Jboss EAP 6.3). One of my beans could not be indexed because it used Java 8 features an I got this sneaky little warning while deploying:

WARN [org.jboss.as.server.deployment] ... Could not index class ... java.lang.IllegalStateException: Unknown tag! pos=20 poolCount = 133

Then at the injection point I got the error:

Unsatisfied dependencies for type ... with qualifiers @Default

The solution is to update the Java annotations index. download new version of jandex (jandex-1.2.3.Final or newer) then put it into

JBOSS_HOME\modules\system\layers\base\org\jboss\jandex\main and then update reference to the new file in module.xml

NOTE: EAP 6.4.x already have this fixed

date('Y-m-d H:i:s'). See the manual for more.

I recommend using composition instead of inheritence whenever possible. Use interfaces but use member objects for base implementation. That way, you can define a factory that constructs your objects to behave in a certain way. If you want to change the behavior then you make a new factory method (or abstract factory) that creates different types of sub-objects.

In some cases, you may find that your primary objects don't need interfaces at all, if all of the mutable behavior is defined in helper objects.

So instead of IPet or PetBase, you might end up with a Pet which has an IFurBehavior parameter. The IFurBehavior parameter is set by the CreateDog() method of the PetFactory. It is this parameter which is called for the shed() method.

If you do this you'll find your code is much more flexible and most of your simple objects deal with very basic system-wide behaviors.

I recommend this pattern even in multiple-inheritence languages.

No problem if all the arrays you are about to use in this scenario are small like in your example.

If you will use this for large blobs (e.g. storing large binary files many Mbs or even Gbs in size into a VARBINARY) then you'd probably be much better off using specific support in SQL Server for reading/writing subsections of such large blobs. Things like READTEXT and UPDATETEXT, or in current versions of SQL Server SUBSTRING.

For more information and examples see either my 2006 article in .NET Magazine ("BLOB + Stream = BlobStream", in Dutch, with complete source code), or an English translation and generalization of this on CodeProject by Peter de Jonghe. Both of these are linked from my weblog.

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

This is very simple. suppose you have 2 window form Form1 and Form2 and you want to send record of textbox1 from Form1 to Form2 and display this record in label1 of Form2; then in Form2 create a label which name is label1 and go to the property of label1 and set 'Modifiers'=public and in Form one create a textBox with id textBox1 and a button of name submit then write the following code on button click event

button1_Click(object sender, EventArgs e)
{
  Form2 obj=new Form2();
  obj.label1.text=textBox1.text.ToString();
  obj.show();
}

thats it... for this way you can bind dataset record to another form's datagridview......

I doubt for Keys.TAB in sendKeys method... if you want to use TAB you need to do something like below:

Actions builder = new Actions(driver);
builder.keyDown(Keys.TAB).perform()

I generally agree with solutions given above. Namely with:

1. Using underscore in for-loop (2 and more lines)
2. Defining a normal while counter (3 and more lines)
3. Declaring a custom class with __nonzero__ implementation (many more lines)

If one is to define an object as in #3 I would recommend implementing protocol for with keyword or apply contextlib.

Further I propose yet another solution. It is a 3 liner and is not of supreme elegance, but it uses itertools package and thus might be of an interest.

from itertools import (chain, repeat)

times = chain(repeat(True, 2), repeat(False))
while next(times):
    print 'do stuff!'

In these example 2 is the number of times to iterate the loop. chain is wrapping two repeat iterators, the first being limited but the second is infinite. Remember that these are true iterator objects, hence they do not require infinite memory. Obviously this is much slower then solution #1. Unless written as a part of a function it might require a clean up for times variable.

if You Want to use Select All Query With Count Option, try this...

 select a.*, (Select count(b.name) from table_name as b where Condition) as totCount from table_name  as a where where Condition

No java.util.List.isEmpty() doesn't check if a list is null.

If you are using Spring framework you can use the CollectionUtils class to check if a list is empty or not. It also takes care of the null references. Following is the code snippet from Spring framework's CollectionUtils class.

public static boolean isEmpty(Collection<?> collection) {
    return (collection == null || collection.isEmpty());
}

Even if you are not using Spring, you can go on and tweak this code to add in your AppUtil class.

The short version

You only need BOOST_ROOT, but you're going to want to disable searching the system for your local Boost if you have multiple installations or cross-compiling for iOS or Android. In which case add Boost_NO_SYSTEM_PATHS is set to false.

set( BOOST_ROOT "" CACHE PATH "Boost library path" )
set( Boost_NO_SYSTEM_PATHS on CACHE BOOL "Do not search system for Boost" )

Normally this is passed on the CMake command-line using the syntax -D<VAR>=value.

The longer version

Officially speaking the FindBoost page states these variables should be used to 'hint' the location of Boost.

This module reads hints about search locations from variables:

BOOST_ROOT             - Preferred installation prefix
 (or BOOSTROOT)
BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
                         specified by these hint variables. Default is OFF.
Boost_ADDITIONAL_VERSIONS
                       - List of Boost versions not known to this module
                         (Boost install locations may contain the version)

This makes a theoretically correct incantation:

cmake -DBoost_NO_SYSTEM_PATHS=TRUE \
      -DBOOST_ROOT=/path/to/boost-dir

When you compile from source

include( ExternalProject )

set( boost_URL "http://sourceforge.net/projects/boost/files/boost/1.63.0/boost_1_63_0.tar.bz2" )
set( boost_SHA1 "9f1dd4fa364a3e3156a77dc17aa562ef06404ff6" )
set( boost_INSTALL ${CMAKE_CURRENT_BINARY_DIR}/third_party/boost )
set( boost_INCLUDE_DIR ${boost_INSTALL}/include )
set( boost_LIB_DIR ${boost_INSTALL}/lib )

ExternalProject_Add( boost
        PREFIX boost
        URL ${boost_URL}
        URL_HASH SHA1=${boost_SHA1}
        BUILD_IN_SOURCE 1
        CONFIGURE_COMMAND
        ./bootstrap.sh
        --with-libraries=filesystem
        --with-libraries=system
        --with-libraries=date_time
        --prefix=<INSTALL_DIR>
        BUILD_COMMAND
        ./b2 install link=static variant=release threading=multi runtime-link=static
        INSTALL_COMMAND ""
        INSTALL_DIR ${boost_INSTALL} )

set( Boost_LIBRARIES
        ${boost_LIB_DIR}/libboost_filesystem.a
        ${boost_LIB_DIR}/libboost_system.a
        ${boost_LIB_DIR}/libboost_date_time.a )
message( STATUS "Boost static libs: " ${Boost_LIBRARIES} )

Then when you call this script you'll need to include the boost.cmake script (mine is in the a subdirectory), include the headers, indicate the dependency, and link the libraries.

include( boost )
include_directories( ${boost_INCLUDE_DIR} )
add_dependencies( MyProject boost )
target_link_libraries( MyProject
                       ${Boost_LIBRARIES} )

How are the "NULL" and "empty varchar" values stored in SQL Server. Why would you want to know that? Or in other words, if you knew the answer, how would you use that information?

And in case I have no user entry for a string field on my UI, should I store a NULL or a ''? It depends on the nature of your field. Ask yourself whether the empty string is a valid value for your field.

If it is (for example, house name in an address) then that might be what you want to store (depending on whether or not you know that the address has no house name).

If it's not (for example, a person's name), then you should store a null, because people don't have blank names (in any culture, so far as I know).

With Swift 3, when you want to filter an array of dictionaries with a predicate based on dictionary keys and values, you may choose one of the following patterns.

#1. Using NSPredicate init(format:arguments:) initializer

If you come from Objective-C, init(format:arguments:) offers a key-value coding style to evaluate your predicate.

Usage:

import Foundation

let array = [["key1": "value1", "key2": "value2"], ["key1": "value3"], ["key3": "value4"]]

let predicate = NSPredicate(format: "key1 == %@", "value1")
//let predicate = NSPredicate(format: "self['key1'] == %@", "value1") // also works
let filteredArray = array.filter(predicate.evaluate)

print(filteredArray) // prints: [["key2": "value2", "key1": "value1"]]

#2. Using NSPredicate init(block:) initializer

As an alternative if you prefer strongly typed APIs over stringly typed APIs, you can use init(block:) initializer.

Usage:

import Foundation

let array = [["key1": "value1", "key2": "value2"], ["key1": "value3"], ["key3": "value4"]]

let dictPredicate = NSPredicate(block: { (obj, _) in
    guard let dict = obj as? [String: String], let value = dict["key1"] else { return false }
    return value == "value1"
})

let filteredArray = array.filter(dictPredicate.evaluate)
print(filteredArray) // prints: [["key2": "value2", "key1": "value1"]]

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

My solution:

ps -o command | grep -v -e "\<ps\>" -e grep -e tail | tail -1

This should be portable across different platforms and shells. It uses ps like other solutions, but it doesn't rely on sed or awk and filters out junk from piping and ps itself so that the shell should always be the last entry. This way we don't need to rely on non-portable PID variables or picking out the right lines and columns.

I've tested on Debian and macOS with Bash, Z shell (zsh), and fish (which doesn't work with most of these solutions without changing the expression specifically for fish, because it uses a different PID variable).

Update:

As noted by @iX3, Typescript 2.4 has support for enum strings.

See:Create an enum with string values in Typescript

Original answer:

For String member values, TypeScript only allows numbers as enum member values. But there are a few solutions/hacks you can implement;

Solution 1:

copied from: https://blog.rsuter.com/how-to-implement-an-enum-with-string-values-in-typescript/

There is a simple solution: Just cast the string literal to any before assigning:

export enum Language {
    English = <any>"English",
    German = <any>"German",
    French = <any>"French",
    Italian = <any>"Italian"
}

solution 2:

copied from: https://basarat.gitbooks.io/typescript/content/docs/types/literal-types.html

You can use a string literal as a type. For example:

let foo: 'Hello';

Here we have created a variable called foo that will only allow the literal value 'Hello' to be assigned to it. This is demonstrated below:

let foo: 'Hello';
foo = 'Bar'; // Error: "Bar" is not assignable to type "Hello"

They are not very useful on their own but can be combined in a type union to create a powerful (and useful) abstraction e.g.:

type CardinalDirection =
    "North"
    | "East"
    | "South"
    | "West";

function move(distance: number, direction: CardinalDirection) {
    // ...
}

move(1,"North"); // Okay
move(1,"Nurth"); // Error!

I think this would do the trick:

function get_wp_installation()
{
    $full_path = getcwd();
    $ar = explode("wp-", $full_path);
    return $ar[0];
}

1. html file and php file both should reside in htdocs folder in c:\apache2 (if you use apache web server).
2. Open html file by typing http://"localhost/html_file_name.html"
3. Now enter Your data in fields.. Your code will run..

if you not design to do loop with in JS e.g. pass to PHP to do loop for you

let decision = {}
decision[code+'#'+row] = event.target.value

this concept may help a bit

def insert_or_update(table_object):
    return session.merge(table_object)

If order is not the matter:

>>> foo='mppmt'
>>> ''.join(set(foo))
'pmt'

To keep the order:

>>> foo='mppmt'
>>> ''.join([j for i,j in enumerate(foo) if j not in foo[:i]])
'mpt'

Do simple compare > and <.

if (dateA>dateB && dateA<dateC)
    //do something

If you care only on time:

if (dateA.TimeOfDay>dateB.TimeOfDay && dateA.TimeOfDay<dateC.TimeOfDay)
    //do something

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

Perhaps this example could explain.

CREATE TABLE `test`(`fla` FLOAT,`flb` FLOAT,`dba` DOUBLE(10,2),`dbb` DOUBLE(10,2)); 

We have a table like this:

+-------+-------------+
| Field | Type        |
+-------+-------------+
| fla   | float       |
| flb   | float       |
| dba   | double(10,2)|
| dbb   | double(10,2)|
+-------+-------------+

For first difference, we try to insert a record with '1.2' to each field:

INSERT INTO `test` values (1.2,1.2,1.2,1.2);

The table showing like this:

SELECT * FROM `test`;

+------+------+------+------+
| fla  | flb  | dba  | dbb  |
+------+------+------+------+
|  1.2 |  1.2 | 1.20 | 1.20 |
+------+------+------+------+

See the difference?

We try to next example:

SELECT fla+flb, dba+dbb FROM `test`;

Hola! We can find the difference like this:

+--------------------+---------+
| fla+flb            | dba+dbb |
+--------------------+---------+
| 2.4000000953674316 |    2.40 |

Can someone point to an RFC indicating that a URL with a space must be encoded?

URIs, and thus URLs, are defined in RFC 3986.

If you look at the grammar defined over there you will eventually note that a space character never can be part of a syntactically legal URL, thus the term "URL with a space" is a contradiction in itself.

using C# 6.0

$"Date-{DateTime.Now:yyyyMMddHHmmss}"

The Heap is divided into young and old generations as follows :

Young Generation : It is place where lived for short period and divided into two spaces:

• Eden Space : When object created using new keyword memory allocated on this space.
• Survivor Space : This is the pool which contains objects which have survived after java garbage collection from Eden space.

Old Generation : This pool basically contains tenured and virtual (reserved) space and will be holding those objects which survived after garbage collection from Young Generation.

• Tenured Space: This memory pool contains objects which survived after multiple garbage collection means object which survived after garbage collection from Survivor space.

Permanent Generation : This memory pool as name also says contain permanent class metadata and descriptors information so PermGen space always reserved for classes and those that is tied to the classes for example static members.

Java8 Update: PermGen is replaced with Metaspace which is very similar.
Main difference is that Metaspace re-sizes dynamically i.e., It can expand at runtime.
Java Metaspace space: unbounded (default)

Code Cache (Virtual or reserved) : If you are using HotSpot Java VM this includes code cache area that containing memory which will be used for compilation and storage of native code.

My solution is that i want data from all docs and i dont want _id, so

User.find({}, {_id:0, keyToShow:1, keyToNotShow:0})

You can go with @greenAfrican example, if it's possible for you to rewrite your function. But if you don't want to rewrite your function, you can wrap it into anonymous function inside apply, like this:

>>> def fxy(x, y):
...     return x * y

>>> df['newcolumn'] = df.apply(lambda x: fxy(x['A'], x['B']), axis=1)
>>> df
    A   B  newcolumn
0  10  20        200
1  20  30        600
2  30  10        300

Another solution:

If you have a static subclass in a non-static outer class, you can access the resources from within the subclass via static variables in the outer class, which you initialise on creation of the outer class. Like

public class Outerclass {

    static String resource1

    public onCreate() {
        resource1 = getString(R.string.text);
    }

    public static class Innerclass {

        public StringGetter (int num) {
            return resource1; 
        }
    }
}

I used it for the getPageTitle(int position) Function of the static FragmentPagerAdapter within my FragmentActivity which is useful because of I8N.

I would think it is also difficult to study design patterns. You have to know more about OOP and some experiences with medium to big application development. For me, I study as a group of developers to make discussion. We follow A Learning Guide To Design Patterns that they have completed the patterns study. There are C# and JavaScript developers join together. It is fancy thing for me is the C# developer write codes in JavaScript and the JavaScript developer do the same thing for C# codes. After I leave a meeting I also research and read a few books at home to review. The better way to understand more and remember in my mind is to do blogging with examples in both C# and JavaScript in here http://tech.wowkhmer.com/category/Design-Patterns.aspx.

I would suggest first before going to each design patterns please understand the name of patterns. In addition if someone know the concept please just explain and give one example not only just programming but in the read world.

for example:

Factory Method:

Read world: I just give money $5, $10 or $20 and it will produce pizza back without knowing anything about how it produce, I just get a small, medium or big pizza depend on money input so that I can eat or do whatever.

Programming: The client just pass parameter value $5, $10 or $20 to the factory method and it will return Pizza object back. So the client can use that object without knowing how it process.

I'm not sure this can help you. It depends on knowledge level of people join in the meeting.

For Ruby Mine users on Windows:

Open file in editor Select the block and press Ctrl+forward slash, you will have selected block starting with #.

Now if you want to un-comment the commented block, press same key combination Ctrl+forward slash again

If you start tinkering with VirtualBox network settings, watch out for this: you might make new network adapters (eth1, eth2), yet have your /etc/network/interfaces still configured for eth0.

Diagnose:

ethtool -i eth0
Cannot get driver information: no such device

Find your interfaces:

ls /sys/class/net
eth1 eth2 lo

Fix it:

Edit /etc/networking/interfaces and replace eth0 with the appropriate interface name (e.g eth1, eth2, etc.)

:%s/eth0/eth2/g

I ran into this exception when try to remove x last items from list. myList.subList(lastIndex, myList.size()).clear(); was the only solution that worked for me.

I have found an interesting solution online.

var shuffled = myList.OrderBy(x => Guid.NewGuid()).ToList();

Here is another option just using CSS that does not over ride every dialog on the page.

The CSS

.no-close .ui-dialog-titlebar-close {display: none }

The HTML

<div class="selector" title="No close button">
    This is a test without a close button
</div>

The Javascript.

$( ".selector" ).dialog({ dialogClass: 'no-close' });

Working Example

Docopt has a C implementation that I thought was quite nice:

From a man-page standardized format describing command line options, docopt infers and creates an argument parser. This got started in Python; the Python version literally just parses the docstring and returns a dict. To do this in C takes a little more work, but it's clean to use and has no external dependencies.

Lot's of good answers here. The easiest way I found was a combination of some of the answers above.

corr = corr.where(np.triu(np.ones(corr.shape), k=1).astype(np.bool))
corr = corr.unstack().transpose()\
    .sort_values(by='column', ascending=False)\
    .dropna()

You need to unicode each element of the list individually

[x.encode('utf-8') for x in tmp]

This should do it:

UPDATE ProductReviews
SET    ProductReviews.status = '0'
FROM   ProductReviews
       INNER JOIN products
         ON ProductReviews.pid = products.id
WHERE  ProductReviews.id = '17190'
       AND products.shopkeeper = '89137'

You're trying to do &(2), &(4) which won't work

#romtest {
  .detailed {
    th {
      &:nth-child(2) {//your styles here}
      &:nth-child(4) {//your styles here}
      &:nth-child(6) {//your styles here}
      }
  }
}

scanf needs to know the size of the data being pointed at by &d to fill it properly, whereas variadic functions promote floats to doubles (not entirely sure why), so printf is always getting a double.

Just as we refer to scrolling class

$( ".scrolling" ).each( function(){
    var img = $( "img", this );
    $(this).width( img.width() * img.length * 1.2 ) 
})

An API (Application Programming Interface) is the means by which third parties can write code that interfaces with other code. A Web Service is a type of API, one that almost always operates over HTTP (though some, like SOAP, can use alternate transports, like SMTP). The official W3C definition mentions that Web Services don't necessarily use HTTP, but this is almost always the case and is usually assumed unless mentioned otherwise.

For examples of web services specifically, see SOAP, REST, and XML-RPC. For an example of another type of API, one written in C for use on a local machine, see the Linux Kernel API.

As far as the protocol goes, a Web service API almost always uses HTTP (hence the Web part), and definitely involves communication over a network. APIs in general can use any means of communication they wish. The Linux kernel API, for example, uses Interrupts to invoke the system calls that comprise its API for calls from user space.

Check this solution too. this solved my DataTable column width issue easily

JQuery DataTables 1.10.20 introduces columns.adjust() method which fix Bootstrap toggle tab issue

 $('a[data-toggle="tab"]').on( 'shown.bs.tab', function (e) {

} );

Please refer the documentation : Scrolling and Bootstrap tabs

Tarkus's answer works well. However, I would suggest replacing VIEWSTATE with SESSION.

The current page's VIEWSTATE only works while the current page posts back to itself and is gone once the user is redirected away to another page. SESSION persists the sort order on more than just the current page's post-back. It persists it across the entire duration of the session. This means that the user can surf around to other pages, and when he comes back to the given page, the sort order he last used still remains. This is usually more convenient.

There are other methods, too, such as persisting user profiles.

I recommend this article for a very good explanation of ViewState and how it works with a web page's life cycle: https://msdn.microsoft.com/en-us/library/ms972976.aspx

To understand the difference between VIEWSTATE, SESSION and other ways of persisting variables, I recommend this article: https://msdn.microsoft.com/en-us/library/75x4ha6s.aspx

Run this command, to check error logs:

I think I have found a sort of work around for the OP question - instead of a transition beginning 'on.load' of the page - I found that using an animation for an opacity fade in had the same effect, (I was looking for the same thing as OP).

So I wanted to have the body text fade in from white(same as site background) to black text colour on page load - and I've only been coding since Monday so I was looking for an 'on.load' style thing code, but don't know JS yet - so here is my code that worked well for me.

#main p {
  animation: fadein 2s;
}
@keyframes fadein {
  from { opacity: 0}
  to   { opacity: 1}
}

And for whatever reason, this doesn't work for .class only #id's(at least not on mine)

Hope this helps - as I know this site helps me a lot!

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

Here is an example of using a dynamic T-SQL query and then extracting the results should you have more than one column of returned values (notice the dynamic table name):

DECLARE 
@strSQLMain nvarchar(1000),
@recAPD_number_key char(10),    
@Census_sub_code varchar(1),
@recAPD_field_name char(100),
@recAPD_table_name char(100),
@NUMBER_KEY varchar(10),

if object_id('[Permits].[dbo].[myTempAPD_Txt]') is not null 

    DROP TABLE [Permits].[dbo].[myTempAPD_Txt]

CREATE TABLE [Permits].[dbo].[myTempAPD_Txt]
(
    [MyCol1] char(10) NULL,
    [MyCol2] char(1) NULL,

)   
-- an example of what @strSQLMain is : @strSQLMain = SELECT @recAPD_number_key = [NUMBER_KEY], @Census_sub_code=TEXT_029 FROM APD_TXT0 WHERE Number_Key = '01-7212' 
SET @strSQLMain = ('INSERT INTO myTempAPD_Txt SELECT [NUMBER_KEY], '+ rtrim(@recAPD_field_name) +' FROM '+ rtrim(@recAPD_table_name) + ' WHERE Number_Key = '''+ rtrim(@Number_Key) +'''')      
EXEC (@strSQLMain)  
SELECT @recAPD_number_key = MyCol1, @Census_sub_code = MyCol2 from [Permits].[dbo].[myTempAPD_Txt]

DROP TABLE [Permits].[dbo].[myTempAPD_Txt]  

Yes, as long as no one is looking over your shoulder at the monitor.

For those looking where to place the image file on the Jupyter machine so that it could be shown from the local file system.

I put my mypic.png into

/root/Images/mypic.png

(that is the Images folder that shows up in the Jupyter online file browser)

In that case I need to put the following line into the Markdown cell to make my pic showing in the notepad:

![My Title](Images/mypic.png)

For example this simple Makefile should be sufficient:

CC=gcc 
CFLAGS=-Wall

all: program
program: program.o
program.o: program.c program.h headers.h

clean:
    rm -f program program.o
run: program
    ./program

Note there must be <tab> on the next line after clean and run, not spaces.

UPDATE Comments below applied

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A

I thought by setting the first element to a null would clear the entire contents of a char array.

That is not correct as you discovered

However, this only sets the first element to null.

Exactly!

You need to use memset to clear all the data, it is not sufficient to set one of the entries to null.

However, if setting an element of the array to null means something special (for example when using a null terminating string in) it might be sufficient to set the first element to null. That way any user of the array will understand that it is empty even though the array still includes the old chars in memory

Two ways I can think of are

var TestApp = React.createClass({
    getComponent: function(index) {
        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>
              <ul>
                <li onClick={this.getComponent.bind(this, 1)}>Component 1</li>
                <li onClick={this.getComponent.bind(this, 2)}>Component 2</li>
                <li onClick={this.getComponent.bind(this, 3)}>Component 3</li>
              </ul>
            </div>
        );
    }
});
React.renderComponent(<TestApp /> , document.getElementById('soln1'));

This is my personal favorite.

var ListItem = React.createClass({
    getInitialState: function() {
        return {
            isSelected: false
        };
    },
    handleClick: function() {
        this.setState({
            isSelected: true
        })
    },
    render: function() {
        var isSelected = this.state.isSelected;
        var style = {
            'background-color': ''
        };
        if (isSelected) {
            style = {
                'background-color': '#ccc'
            };
        }
        return (
            <li onClick={this.handleClick} style={style}>{this.props.content}</li>
        );
    }
});

var TestApp2 = React.createClass({
    getComponent: function(index) {
        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>
             <ul>
              <ListItem content="Component 1" />
              <ListItem content="Component 2" />
              <ListItem content="Component 3" />
             </ul>
            </div>
        );
    }
});
React.renderComponent(<TestApp2 /> , document.getElementById('soln2'));

Here is a DEMO

I hope this helps.

Remember that Raspberry Pi does not have real time clock. So even you are connected to internet have to set the time every time you power on or restart.

This is how it works:

1. Type sudo raspi-config in the Raspberry Pi command line
2. Internationalization options
3. Change Time Zone
4. Select geographical area
5. Select city or region
6. Reboot your pi

Next thing you can set time using this command

sudo date -s "Mon Aug  12 20:14:11 UTC 2014"

More about data and time

man date

When Pi is connected to computer should have to manually set data and time

        }

You can also use the CSS calc() function to subtract the width of your padding from the percentage of your container's width.

An example:

width: calc((100%) - (32px))

Just be sure to make the subtracted width equal to the total padding, not just one half. If you pad both sides of the inner div with 16px, then you should subtract 32px from the final width, assuming that the example below is what you want to achieve.

.outer {_x000D_
  width: 200px;_x000D_
  height: 120px;_x000D_
  background-color: black;_x000D_
}_x000D_
_x000D_
.inner {_x000D_
  height: 40px;_x000D_
  top: 30px;_x000D_
  position: relative;_x000D_
  padding: 16px;_x000D_
  background-color: teal;_x000D_
}_x000D_
_x000D_
#inner-1 {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#inner-2 {_x000D_
  width: calc((100%) - (32px));_x000D_
}

<div class="outer" id="outer-1">_x000D_
  <div class="inner" id="inner-1"> width of 100% </div>_x000D_
</div>_x000D_
_x000D_
<br>_x000D_
<br>_x000D_
_x000D_
<div class="outer" id="outer-2">_x000D_
  <div class="inner" id="inner-2"> width of 100% - 16px </div>_x000D_
</div>

1: I have downloaded the mysql-connector-java-5.1.24-bin.jar

Okay.

2: I have created a lib folder in my project and put the jar in there.

Wrong. You need to drop JAR in /WEB-INF/lib folder. You don't need to create any additional folders.

3: properties of project->build path->add JAR and selected the JAR above.

Unnecessary. Undo it all to avoid possible conflicts.

4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

This exception can have 2 causes:

1. JDBC driver is not in runtime classpath. This is to be solved by doing 2) the right way.

2. JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.

   jdbc:mysql://localhost:3306/mysql
   

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender ! 
[1] 8
[1] 9
[1] 10

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

Add padding. Padding the element will increase the space between its content and its border. However, note that a box-shadow will begin outside the border, not the content, meaning you can't put space between the shadow and the box. Alternatively you could use :before or :after pseudo selectors on the element to create a slightly bigger box that you place the shadow on, like so: http://jsbin.com/aqemew/edit#source

Provide a path (myfolder in this case) and just run:

git diff myfolder/

What about this approach? Works for me. It is also used in django-registration.

def get_request_root_url(self):
    scheme = 'https' if self.request.is_secure() else 'http'
    site = get_current_site(self.request)
    return '%s://%s' % (scheme, site)

You can use 'this' in event handler:

document.getElementById("preview").onmouseover = function() {
    alert(this.id);
}

Or pass event object to handler as follows:

document.getElementById("preview").onmouseover = function(evt) {
    alert(evt.target.id);
}

It's recommended to use attachEvent(for IE < 9)/addEventListener(IE9 and other browsers) to attach events. Example above is for brevity.

function myHandler(evt) {
    alert(evt.target.id);
}

var el = document.getElementById("preview");
if (el.addEventListener){
    el.addEventListener('click', myHandler, false); 
} else if (el.attachEvent){
    el.attachEvent('onclick', myHandler);
}

global temp

temp =''

s = ' '

def remove_strings(text):

    global temp 

    if text == '':

        return temp

    start = text.find('<')

    end = text.find('>')

    if start == -1 and end == -1 :

        temp = temp + text

    return temp

newstring = text[end+1:]

fresh_start = newstring.find('<')

if newstring[:fresh_start] != '':

    temp += s+newstring[:fresh_start]

remove_strings(newstring[fresh_start:])

return temp

Ramil Amr's answer works only for the & character. If you have some other special characters, you should use PHP's htmlspecialchars() and JS's encodeURIComponent().

You can write:

var wysiwyg_clean = encodeURIComponent(wysiwyg);

And on the server side:

htmlspecialchars($_POST['wysiwyg']);

This will make sure that AJAX will pass the data as expected, and that PHP (in case your'e insreting the data to a database) will make sure the data works as expected.

I would use the following. It should work just fine, and doesn't seem ugly, at least to me:

singleString <- paste(readLines("foo.txt"), collapse=" ")

I just want to report my solution in case anyone has the similar situation as I do. I have Visual Studio 2013 with update 5 and ReSharper 8.2.3. My project is ASP.NET MVC 5.

Normally, I'm good at keep updating my extension packages. Just recently, I found out all my views are red and showing "cannot resolve view xxxx". I tried the clear cache and suspend ReSharper and resume ReSharper solution, but the error will come back once I build the project.

I checked my ReSharper extensions, and then I uninstalled the resharper.ExternalAnnotations package (8.2.3005) and re-install the previous version from gallery (8.2.3000.5176). This seems to have fixed my problem.

If you are using six, you can try this, by which utilizing the latest Python 3 API and can run in both Python 2/3:

import six

if six.PY2:
    # FileNotFoundError is only available since Python 3.3
    FileNotFoundError = IOError
    from io import open

fname = 'index.rst'
try:
    with open(fname, "rt", encoding="utf-8") as f:
        pass
        # do_something_with_f ...
except FileNotFoundError:
    print('Oops.')

And, Python 2 support abandon is just deleting everything related to six.

In pip3

pip3 uninstall jupyterlab

if the page have one <a> It Works,but,many <a> ,have to use var href = $(this).attr('href');

In my case, I was updating the server-sided datatable twice and it gives me this error. Hope it helps someone.

def avg(l):
    """uses floating-point division."""
    return sum(l) / float(len(l))

Examples:

l2 = [0,0,0]

print(avg(l1)) # 9.0
print(avg(l2)) # 0.0

I've an object (basically a VO) in Java and I don't know its type. I need to get values which are not null in that object.

Maybe you don't necessary need reflection for that -- here is a plain OO design that might solve your problem:

1. Add an interface Validation which expose a method validate which checks the fields and return whatever is appropriate.
2. Implement the interface and the method for all VO.
3. When you get a VO, even if it's concrete type is unknown, you can typecast it to Validation and check that easily.

I guess that you need the field that are null to display an error message in a generic way, so that should be enough. Let me know if this doesn't work for you for some reason.

Yes you can ignore this <br>. You may need this especially in case of responsive design where you need to remove breaks for mobile devices.

HTML

<h2>

  Where ever you go <br class="break"> i am there.

</h2>

CSS for mobile example

/* Resize the browser window to check */

@media (max-width: 640px) 
{
  .break {display: none;}
}

Check out this Codepen:
https://codepen.io/fluidbrush/pen/pojGQyM

Ran in to this today.

I wrote some code that looked like this:

app.controller('ctrlr', function($scope, $http){
    $http.get('localhost:3000').success(function(data) {
        $scope.stuff = data;
    });
});

...but it should've looked like this:

app.controller('ctrlr', function($scope, $http){
    $http.get('http://localhost:3000').success(function(data) {
        $scope.stuff = data;
    });
});

The only difference was the lack of http:// in the second snippet of code.

Just wanted to put that out there in case there are others with a similar issue.

As mentioned, you should use jsPDF and html2canvas. I've also found a function inside issues of jsPDF which splits automatically your pdf into multiple pages (sources)

function makePDF() {

    var quotes = document.getElementById('container-fluid');

    html2canvas(quotes, {
        onrendered: function(canvas) {

        //! MAKE YOUR PDF
        var pdf = new jsPDF('p', 'pt', 'letter');

        for (var i = 0; i <= quotes.clientHeight/980; i++) {
            //! This is all just html2canvas stuff
            var srcImg  = canvas;
            var sX      = 0;
            var sY      = 980*i; // start 980 pixels down for every new page
            var sWidth  = 900;
            var sHeight = 980;
            var dX      = 0;
            var dY      = 0;
            var dWidth  = 900;
            var dHeight = 980;

            window.onePageCanvas = document.createElement("canvas");
            onePageCanvas.setAttribute('width', 900);
            onePageCanvas.setAttribute('height', 980);
            var ctx = onePageCanvas.getContext('2d');
            // details on this usage of this function: 
            // https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images#Slicing
            ctx.drawImage(srcImg,sX,sY,sWidth,sHeight,dX,dY,dWidth,dHeight);

            // document.body.appendChild(canvas);
            var canvasDataURL = onePageCanvas.toDataURL("image/png", 1.0);

            var width         = onePageCanvas.width;
            var height        = onePageCanvas.clientHeight;

            //! If we're on anything other than the first page,
            // add another page
            if (i > 0) {
                pdf.addPage(612, 791); //8.5" x 11" in pts (in*72)
            }
            //! now we declare that we're working on that page
            pdf.setPage(i+1);
            //! now we add content to that page!
            pdf.addImage(canvasDataURL, 'PNG', 20, 40, (width*.62), (height*.62));

        }
        //! after the for loop is finished running, we save the pdf.
        pdf.save('test.pdf');
    }
  });
}

When using in Maven, update artifact junit:junit from e.g. 4.8.2 to 4.11.

Using FileProvider from support library you have to manually grant and revoke permissions(at runtime) for other apps to read specific Uri. Use Context.grantUriPermission and Context.revokeUriPermission methods.

For example:

//grant permision for app with package "packegeName", eg. before starting other app via intent
context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);

//revoke permisions
context.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);

As a last resort, if you can't provide package name you can grant the permission to all apps that can handle specific intent:

//grant permisions for all apps that can handle given intent
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
...
List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
    String packageName = resolveInfo.activityInfo.packageName;
    context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}

Alternative method according to the documentation:

• Put the content URI in an Intent by calling setData().
• Next, call the method Intent.setFlags() with either FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION or both.

• Finally, send the Intent to another app. Most often, you do this by calling setResult().

  Permissions granted in an Intent remain in effect while the stack of the receiving Activity is active. When the stack finishes, the
  permissions are automatically removed. Permissions granted to one
  Activity in a client app are automatically extended to other
  components of that app.

Btw. if you need to, you can copy source of FileProvider and change attachInfo method to prevent provider from checking if it is exported.

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

When I got this error it appeared to be due to a security setting. When I changed the "Connect As" property to an administrator then I no longer got the message.

Obviously this isn't a good solution for a production environment - one should probably grant the least privileges necessary for the user IIS is going to be using by default. I'll update this answer if I learn more.

Adding executable permissions, recursively, to all files (not folders) within the current folder with sh extension:

find . -name '*.sh' -type f | xargs chmod +x

* Notice the pipe (|)

What you expect is the synchronous (blocking) type request.

var it_works = false;

jQuery.ajax({
  type: "POST",
  url: 'some_file.php',
  success: function (data) {
    it_works = true;
  }, 
  async: false // <- this turns it into synchronous
});?

// Execution is BLOCKED until request finishes.

// it_works is available
alert(it_works);

Requests are asynchronous (non-blocking) by default which means that the browser won't wait for them to be completed in order to continue its work. That's why your alert got wrong result.

Now, with jQuery.ajax you can optionally set the request to be synchronous, which means that the script will only continue to run after the request is finished.

The RECOMMENDED way, however, is to refactor your code so that the data would be passed to a callback function as soon as the request is finished. This is preferred because blocking execution means blocking the UI which is unacceptable. Do it this way:

$.post("some_file.php", '', function(data) {
    iDependOnMyParameter(data);
});

function iDependOnMyParameter(param) {
    // You should do your work here that depends on the result of the request!
    alert(param)
}

// All code here should be INDEPENDENT of the result of your AJAX request
// ...

Asynchronous programming is slightly more complicated because the consequence of making a request is encapsulated in a function instead of following the request statement. But the realtime behavior that the user experiences can be significantly better because they will not see a sluggish server or sluggish network cause the browser to act as though it had crashed. Synchronous programming is disrespectful and should not be employed in applications which are used by people.

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

On a Hungarian keyboard it is Ctrl + ú.

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.

[Context] In a virtual machine of WinXP.

My "java.exe" was in the Oracle11g folder, under the path "C:\Oracle11g\product\11.2.0\dbhome_1\jdk\bin\java.exe".

Hope it helps!!

Remove "values" when you're appending a group of rows, and remove the extra parentheses. You can avoid the circular reference by using an alias for avg(CurrencyColumn) (as you did in your example) or by not using an alias at all.

If the column names are the same in both tables, your query would be like this:

INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn) as CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn;

And it would work without an alias:

INSERT INTO Table2 (LongIntColumn, Junk)
SELECT LongIntColumn, avg(CurrencyColumn)
FROM Table1
GROUP BY LongIntColumn;

A better use of jAndy's answer to implement a polling function that polls every interval seconds, and ends after timeout seconds.

function pollFunc(fn, timeout, interval) {
    var startTime = (new Date()).getTime();
    interval = interval || 1000;

    (function p() {
        fn();
        if (((new Date).getTime() - startTime ) <= timeout)  {
            setTimeout(p, interval);
        }
    })();
}

pollFunc(sendHeartBeat, 60000, 1000);

UPDATE

As per the comment, updating it for the ability of the passed function to stop the polling:

function pollFunc(fn, timeout, interval) {
    var startTime = (new Date()).getTime();
    interval = interval || 1000,
    canPoll = true;

    (function p() {
        canPoll = ((new Date).getTime() - startTime ) <= timeout;
        if (!fn() && canPoll)  { // ensures the function exucutes
            setTimeout(p, interval);
        }
    })();
}

pollFunc(sendHeartBeat, 60000, 1000);

function sendHeartBeat(params) {
    ...
    ...
    if (receivedData) {
        // no need to execute further
        return true; // or false, change the IIFE inside condition accordingly.
    }
}

Dumping a database with a specific encoding and try to restore it on another database with a different encoding could result in data corruption. Data encoding must be set BEFORE any data is inserted into the database.

Check this : When copying any other database, the encoding and locale settings cannot be changed from those of the source database, because that might result in corrupt data.

And this : Some locale categories must have their values fixed when the database is created. You can use different settings for different databases, but once a database is created, you cannot change them for that database anymore. LC_COLLATE and LC_CTYPE are these categories. They affect the sort order of indexes, so they must be kept fixed, or indexes on text columns would become corrupt. (But you can alleviate this restriction using collations, as discussed in Section 22.2.) The default values for these categories are determined when initdb is run, and those values are used when new databases are created, unless specified otherwise in the CREATE DATABASE command.

I would rather rebuild everything from the begining properly with a correct local encoding on your debian OS as explained here :

su root

Reconfigure your local settings :

dpkg-reconfigure locales

Choose your locale (like for instance for french in Switzerland : fr_CH.UTF8)

Uninstall and clean properly postgresql :

apt-get --purge remove postgresql\*
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

Re-install postgresql :

aptitude install postgresql-9.1 postgresql-contrib-9.1 postgresql-doc-9.1

Now any new database will be automatically be created with correct encoding, LC_TYPE (character classification), and LC_COLLATE (string sort order).

It's hard to tell what you're going for in that example. exports = is about exporting from external modules, but the code sample you linked is an internal module.

Rule of thumb: If you write module foo { ... }, you're writing an internal module; if you write export something something at top-level in a file, you're writing an external module. It's somewhat rare that you'd actually write export module foo at top-level (since then you'd be double-nesting the name), and it's even rarer that you'd write module foo in a file that had a top-level export (since foo would not be externally visible).

The following things make sense (each scenario delineated by a horizontal rule):

// An internal module named SayHi with an exported function 'foo'
module SayHi {
    export function foo() {
       console.log("Hi");
    }

    export class bar { }
}

// N.B. this line could be in another file that has a
// <reference> tag to the file that has 'module SayHi' in it
SayHi.foo();
var b = new SayHi.bar();

file1.ts

// This *file* is an external module because it has a top-level 'export'
export function foo() {
    console.log('hi');
}

export class bar { }

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();

file1.ts

// This will only work in 0.9.0+. This file is an external
// module because it has a top-level 'export'
function f() { }
function g() { }
export = { alpha: f, beta: g };

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = require('file1');
f1.alpha(); // invokes f
f1.beta(); // invokes g

Since the question mentioned third-party libraries and not all packages then you probably want to fall back to using wildcards.

A use case being: I just want to update all my packages that are obtained from the Github VCS, then you would just say:

go get -u github.com/... // ('...' being the wildcard). 

This would go ahead and only update your github packages in the current $GOPATH

Same applies for within a VCS too, say you want to only upgrade all the packages from ogranizaiton A's repo's since as they have released a hotfix you depend on:

go get -u github.com/orgA/...

By clicking "Finish", you'll effectively issue a bind to the server using the credentials, auth mechanism, and password you've specified. You'll be prompted if the bind does not work.

The newest versions of pandas now include a built-in function for iterating over rows.

for index, row in df.iterrows():

    # do some logic here

Or, if you want it faster use itertuples()

But, unutbu's suggestion to use numpy functions to avoid iterating over rows will produce the fastest code.

Currently, they are the same. but previously

1. Somewhere on the net, I read that,

VARCHAR is reserved by Oracle to support distinction between NULL and empty string in future, as ANSI standard prescribes.

VARCHAR2 does not distinguish between a NULL and empty string, and never will.

2. Also,

Emp_name varchar(10) - if you enter value less than 10 digits then remaining space cannot be deleted. it used total of 10 spaces.

Emp_name varchar2(10) - if you enter value less than 10 digits then remaining space is automatically deleted

You can use a named vector.

With base R (maybe somewhat clunky):

x = data.frame(q = 1, w = 2, e = 3) 

rename_vec <- c(q = "A", e = "B")

names(x) <- ifelse(is.na(rename_vec[names(x)]), names(x), rename_vec[names(x)])

x
#>   A w B
#> 1 1 2 3

Or a dplyr option with !!!:

library(dplyr)

rename_vec <- c(A = "q", B = "e") # the names are just the other way round than in the base R way!

x %>% rename(!!!rename_vec)
#>   A w B
#> 1 1 2 3

The latter works because the 'big-bang' operator !!! is forcing evaluation of a list or a vector.

?`!!`

!!! forces-splice a list of objects. The elements of the list are spliced in place, meaning that they each become one single argument.

According to http://docs.python.org/dev/py3k/library/stdtypes.html#dictionary-view-objects , the keys(), values() and items() methods of a dict will return corresponding iterators whose orders correspond. However, I am unable to find a reference to the official documentation for python 2.x for the same thing.

So as far as I can tell, the answer is yes, but only in python 3.0+

FirebaseInstanceIdService is now deprecated. you should get the Token in the onNewToken method in the FirebaseMessagingService.

Pure bash, no basename, no variable juggling. Set a string and echo:

p=/the/path/foo.txt
echo "${p//+(*\/|.*)}"

Output:

foo

Note: the bash extglob option must be "on", (Ubuntu sets extglob "on" by default), if it's not, do:

shopt -s extglob

Walking through the ${p//+(*\/|.*)}:

1. ${p -- start with $p.
2. // substitute every instance of the pattern that follows.
3. +( match one or more of the pattern list in parenthesis, (i.e. until item #7 below).
4. 1st pattern: *\/ matches anything before a literal "/" char.
5. pattern separator | which in this instance acts like a logical OR.
6. 2nd pattern: .* matches anything after a literal "." -- that is, in bash the "." is just a period char, and not a regex dot.
7. ) end pattern list.
8. } end parameter expansion. With a string substitution, there's usually another / there, followed by a replacement string. But since there's no / there, the matched patterns are substituted with nothing; this deletes the matches.

Relevant man bash background:

1. pattern substitution:

  ${parameter/pattern/string}
          Pattern substitution.  The pattern is expanded to produce a pat
          tern just as in pathname expansion.  Parameter is  expanded  and
          the  longest match of pattern against its value is replaced with
          string.  If pattern begins with /, all matches  of  pattern  are
          replaced   with  string.   Normally  only  the  first  match  is
          replaced.  If pattern begins with #, it must match at the begin-
          ning of the expanded value of parameter.  If pattern begins with
          %, it must match at the end of the expanded value of  parameter.
          If string is null, matches of pattern are deleted and the / fol
          lowing pattern may be omitted.  If parameter is @ or *, the sub
          stitution  operation  is applied to each positional parameter in
          turn, and the expansion is the resultant list.  If parameter  is
          an  array  variable  subscripted  with  @ or *, the substitution
          operation is applied to each member of the array  in  turn,  and
          the expansion is the resultant list.

2. extended pattern matching:

  If the extglob shell option is enabled using the shopt builtin, several
   extended  pattern  matching operators are recognized.  In the following
   description, a pattern-list is a list of one or more patterns separated
   by a |.  Composite patterns may be formed using one or more of the fol
   lowing sub-patterns:

          ?(pattern-list)
                 Matches zero or one occurrence of the given patterns
          *(pattern-list)
                 Matches zero or more occurrences of the given patterns
          +(pattern-list)
                 Matches one or more occurrences of the given patterns
          @(pattern-list)
                 Matches one of the given patterns
          !(pattern-list)
                 Matches anything except one of the given patterns

It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.

It's not the same doing a select distinct at the beginning because you are wasting all the calculated rows from the result.

select a.FirstName, a.LastName, v.District
from AddTbl a order by Firstname
natural join (select distinct LastName from
            ValTbl v  where a.LastName = v.LastName)

try that.

There's no legitimate way you can do it.

The screenshot was very helpful - the following code will do the job (assuming data is located in column A starting A1):

Sub RemoveRows()

Dim i As Long

i = 1

Do While i <= ThisWorkbook.ActiveSheet.Range("A1").CurrentRegion.Rows.Count

    If InStr(1, ThisWorkbook.ActiveSheet.Cells(i, 1).Text, "-", vbTextCompare) > 0 Then
        ThisWorkbook.ActiveSheet.Cells(i, 1).EntireRow.Delete
    Else
        i = i + 1
    End If

Loop

End Sub

Below code absolutely worked for me to update File extension.

Ex: abc.pdf to abc.txt

Filepath = "Pls mention your Filepath"

Set objFso = CreateObject("Scripting.FileSystemObject")

'' Below line of code is to get the object for Folder where list of files are located 
Set objFolder = objFso.GetFolder(Filepath)

'' Below line of code used to get the collection object to hold list of files located in the Filepath.
Set FileCollection = objFolder.Files

For Each file In FileCollection

    WScript.Echo "File name ->" + file.Name
    ''Instr used to Return the position of the first occurrence of "." within the File name
    s = InStr(1, file.Name, ".",1)
    WScript.Echo s
    WScript.Echo "Extn --> " + Mid(file.Name, s, Len(file.Name))

    'Left(file.Name,s-1) = Used to fetch the file name without extension
    ' Move method is used to move the file in the Desitnation folder you mentioned
    file.Move(Filepath & Left(file.Name,s-1)&".txt")

One more option, not exactly what you asked, but can be useful:

Go to Settings -> Editor -> File and code templates -> Includes tab (on the right). There is a template header for the new files, you can use the username here:

/**
 * @author myname
 */

For system username use:

/**
 * @author ${USER}
 */

You can use Serial.readString() and Serial.readStringUntil() to parse strings from Serial on the Arduino.

You can also use Serial.parseInt() to read integer values from serial.

int x;
String str;
    
void loop() 
{
     if(Serial.available() > 0)
     {
        str = Serial.readStringUntil('\n');
        x = Serial.parseInt();
     }
}

The value to send over serial would be my string\n5 and the result would be str = "my string" and x = 5

It's true, they are both - or more precisely, they are "inline block" elements. This means that they flow inline like text, but also have a width and height like block elements.

A good place to start learning how to manipulate pages s the Mozilla Developer Network, they've got a great tutorial about the DOM.

One way you could do it is with document.write, which writes html at the end of the currently loaded part of the document - in this case, after the script tag.

<script>
  var name = prompt("What's your name?");
  document.write("<p>" + name.length + "</p>");
</script>

But it's not a very clean way of doing it. Keep document.write for testing purpose because in most cases you can't predict where it will append the content.

EDIT: Here, the "clever" way would be to do something like this:

<script type="text/javascript">
  window.addEventListener("load", function(e) {
    var name = prompt("What's your name?") || "";
    var text = document.createTextNode(name.length);
    document.getElementById("nameLength").appendChild(text);
  });
</script>
<p id="nameLength"></p>

But people are generally lazy and you'll often see .innerHTML = "something" instead of a text node.

.apply() takes in a function as the first parameter; pass in the label_race function as so:

df['race_label'] = df.apply(label_race, axis=1)

You don't need to make a lambda function to pass in a function.

We store latitude/longitude X 1,000,000 in our oracle database as NUMBERS to avoid round off errors with doubles.

Given that latitude/longitude to the 6th decimal place was 10 cm accuracy that was all we needed. Many other databases also store lat/long to the 6th decimal place.

You can use the to_pydatetime method to be more explicit:

In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)

In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)

It's also available on a DatetimeIndex:

In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')

In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
       datetime.datetime(2011, 1, 11, 0, 0),
       datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)

To run the command without a shell, pass the command as a list and implement the redirection in Python using [subprocess]:

#!/usr/bin/env python
import subprocess

with open('test.nt', 'wb', 0) as file:
    subprocess.check_call("cwm --rdf test.rdf --ntriples".split(),
                          stdout=file)

Note: no > test.nt at the end. stdout=file implements the redirection.

To run the command using the shell in Python, pass the command as a string and enable shell=True:

#!/usr/bin/env python
import subprocess

subprocess.check_call("cwm --rdf test.rdf --ntriples > test.nt",
                      shell=True)

Here's the shell is responsible for the output redirection (> test.nt is in the command).

To run a bash command that uses bashisms, specify the bash executable explicitly e.g., to emulate bash process substitution:

#!/usr/bin/env python
import subprocess

subprocess.check_call('program <(command) <(another-command)',
                      shell=True, executable='/bin/bash')

Simple and effective solution: Instead of using the LoadXml() method use the Load() method

For example:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("sample.xml");

When the parent panel has locked property set to true, we could not change the location property and the location property will act like read only by that time.

It worked for me like this:

Go to Wordpress Admin Dashboard > “Settings” > “Permalinks” > “Common settings”, set the radio button to “Custom Structure” and paste into the text box:

/index.php/%year%/%monthnum%/%day%/%postname%/

and click the Save button.

How I accomplished this...

inputChangeHandler: function(event) {
  var key = event.target.id
  var val = event.target.value
  var obj  = {}
  obj[key] = val
  this.setState(obj)
},

Select the System.Web.Mvc assembly in the "References" folder in the solution explorer. Bring up the properties window (F4) and check the Version

database_password: password would between quotes: " or '.

like so:

database_password: "password"

use:

my_function({width:12});

Instead of:

my_function(width:12);

I found using while IFS='=' read -r to be a bit slow (I don't know why, maybe someone could briefly explain in a comment or point to a SO answer?). I also found @Nicolai answer very neat as a one-liner, but very inefficient as it will scan the entire properties file over and over again for every single call of prop.

I found a solution that answers the question, performs well and it is a one-liner (bit verbose line though).

The solution does sourcing but massages the contents before sourcing:

#!/usr/bin/env bash

source <(grep -v '^ *#' ./app.properties | grep '[^ ] *=' | awk '{split($0,a,"="); print gensub(/\./, "_", "g", a[1]) "=" a[2]}')

echo $db_uat_user

Explanation:

grep -v '^ *#': discard comment lines grep '[^ ] *=': discards lines without = split($0,a,"="): splits line at = and stores into array a, i.e. a[1] is the key, a[2] is the value gensub(/\./, "_", "g", a[1]): replaces . with _ print gensub... "=" a[2]} concatenates the result of gensub above with = and value.

Edit: As others pointed out, there are some incompatibilities issues (awk) and also it does not validate the contents to see if every line of the property file is actually a kv pair. But the goal here is to show the general idea for a solution that is both fast and clean. Sourcing seems to be the way to go as it loads the properties once that can be used multiple times.

content: "";
background-image: url("yourimage.jpg");
background-size: 30px, 30px;

The smallest change to fix this would be to change

onClick="document.getElementById("datepicker").click()">

to

onClick="$('#datepicker').click()">

click() is a jQuery method. Also, you had a collision between the double-quotes used for the HTML element attribute and those use for the JavaScript function argument.

I was intrigued by the answer from @Jerry Coffin, which suggested that the ordered map would exhibit performance increases on long strings, after some experimentation (which can be downloaded from pastebin), I've found that this seems to hold true only for collections of random strings, when the map is initialised with a sorted dictionary (which contain words with considerable amounts of prefix-overlap), this rule breaks down, presumably because of the increased tree depth necessary to retrieve value. The results are shown below, the 1st number column is insert time, 2nd is fetch time.

g++ -g -O3 --std=c++0x   -c -o stdtests.o stdtests.cpp
g++ -o stdtests stdtests.o
gmurphy@interloper:HashTests$ ./stdtests
# 1st number column is insert time, 2nd is fetch time
 ** Integer Keys ** 
 unordered:      137      15
   ordered:      168      81
 ** Random String Keys ** 
 unordered:       55      50
   ordered:       33      31
 ** Real Words Keys ** 
 unordered:      278      76
   ordered:      516     298

In case you have a .properties file or a .ini file

Actually in case if you have any file that has key value pairs like this:

someKey=someValue
someOtherKey=someOtherValue

You can import that into webpack by a npm module called properties-reader

I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.

1. Import that from dependencies section in package.json

"properties-reader": "0.0.16"

2. Import this module into webpack.config.js on top

const PropertiesReader = require('properties-reader');

3. Read the properties file

const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;

4. Import this constant as config

externals: { 'Config': JSON.stringify(appProperties) }

5. Use it as the same way as mentioned in the accepted answer

var Config = require('Config') fetchData(Config.serverUrl + '/Enterprises/...')

The line: result = result * i should be indented (it is the body of the for-loop).

Or - you have mixed space and tab characters

@sz3, funny enough today I had to do exactly what you were trying to achieve: 'load a specific CSS file only when a user access' a specific page. So I used the solution above.

But I am here to answer your last question: 'where exactly should I put the code. Any ideas?'

You were right including the code into the resolve, but you need to change a bit the format.

Take a look at the code below:

.when('/home', {
  title:'Home - ' + siteName,
  bodyClass: 'home',
  templateUrl: function(params) {
    return 'views/home.html';
  },
  controler: 'homeCtrl',
  resolve: {
    style : function(){
      /* check if already exists first - note ID used on link element*/
      /* could also track within scope object*/
      if( !angular.element('link#mobile').length){
        angular.element('head').append('<link id="home" href="home.css" rel="stylesheet">');
      }
    }
  }
})

I've just tested and it's working fine, it injects the html and it loads my 'home.css' only when I hit the '/home' route.

Full explanation can be found here, but basically resolve: should get an object in the format

{
  'key' : string or function()
} 

You can name the 'key' anything you like - in my case I called 'style'.

Then for the value you have two options:

• If it's a string, then it is an alias for a service.

• If it's function, then it is injected and the return value is treated as the dependency.

The main point here is that the code inside the function is going to be executed before before the controller is instantiated and the $routeChangeSuccess event is fired.

Hope that helps.

Multi column unique indexes do not work in MySQL if you have a NULL value in row as MySQL treats NULL as a unique value and at least currently has no logic to work around it in multi-column indexes. Yes the behavior is insane, because it limits a lot of legitimate applications of multi-column indexes, but it is what it is... As of yet, it is a bug that has been stamped with "will not fix" on the MySQL bug-track...

How's this for a work around (using an actual table)?

table {
    border-collapse: collapse;
}

tr.row {
    border-bottom: solid white 30px; /* change "white" to your background color */
}

It's not as dynamic, since you have to explicitly set the color of the border (unless there's a way around that too), but this is something I'm experimenting with on a project of my own.

Edit to include comments regarding transparent:

tr.row {
    border-bottom: 30px solid transparent;
}

By iterating I learned that the Token field and the token in an endpoint can be the same. So I set them to be the same as the user token and it works! Also check that the user has privileges to make a job.

Anyway, you can check access.log and see if Bitbucket makes a try or not.

P.S. Also a link to Bitbucket Documentation. May some day it will become more useful.

While you should keep your NuGet packages.config file, you should exclude the packages folder:

#NuGet
packages/

I typically don't store binaries, or anything generated from my source, in source control. There are differing opinions on this however. If it makes things easier for your build system, do it! I would however, argue that you are not versioning these dependencies, so they will just take up space in your repository. Storing the binaries in a central location, then relying on the packages.config file to indicate which version is needed is a better solution, in my opinion.

Screen.FromControl(this).Bounds

Calculate x/y (your actual numbers here), and press a b/c key, which is 3rd one below Shift key.

Specify the type of the pointer to your comparison function as the 3rd type into the map, and provide the function pointer to the map constructor:
map<keyType, valueType, typeOfPointerToFunction> mapName(pointerToComparisonFunction);

Take a look at the example below for providing a comparison function to a map, with vector iterator as key and int as value.

#include "headers.h"

bool int_vector_iter_comp(const vector<int>::iterator iter1, const vector<int>::iterator iter2) {
    return *iter1 < *iter2;

    map<vector<int>::iterator, int> default_comparison;

    // Providing custom comparison function
    // Basic version
    map<vector<int>::iterator, int,
        bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2)>
        basic(int_vector_iter_comp);

    // use decltype
    map<vector<int>::iterator, int, decltype(int_vector_iter_comp)*> with_decltype(&int_vector_iter_comp);

    // Use type alias or using
    typedef bool my_predicate(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate*> with_typedef(&int_vector_iter_comp);

    using my_predicate_pointer_type = bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate_pointer_type> with_using(&int_vector_iter_comp);


    // Testing 
    vector<int> v = {1, 2, 3};

    cout << "size: " << with_decltype.size() << endl;
    for (auto& p : with_decltype) {
        cout << *(p.first) << ": " << p.second << endl;
    }

    with_typedef.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
