• Convert the ISO8601 string to date

  let isoDate = "2016-04-14T10:44:00+0000"
  
  let dateFormatter = DateFormatter()
  dateFormatter.locale = Locale(identifier: "en_US_POSIX") // set locale to reliable US_POSIX
  dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
  let date = dateFormatter.date(from:isoDate)!
  

• Get the date components for year, month, day and hour from the date

  let calendar = Calendar.current
  let components = calendar.dateComponents([.year, .month, .day, .hour], from: date)
  

• Finally create a new Date object and strip minutes and seconds

  let finalDate = calendar.date(from:components)
  

Consider also the convenience formatter ISO8601DateFormatter introduced in iOS 10 / macOS 12:

let isoDate = "2016-04-14T10:44:00+0000"

let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from:isoDate)!

How about this

var parsed = new Function('return ' + stringifiedJSON )();

This is a safer alternative for eval.

var stringifiedJSON = '{"hello":"world"}';_x000D_
var parsed = new Function('return ' + stringifiedJSON)();_x000D_
alert(parsed.hello);

Use

git clone --depth=1 --branch=master git://someserver/somerepo dirformynewrepo
rm -rf ./dirformynewrepo/.git

• The depth option will make sure to copy the least bit of history possible to get that repo.
• The branch option is optional and if not specified would get master.
• The second line will make your directory dirformynewrepo not a Git repository any more.
• If you're doing recursive submodule clone, the depth and branch parameter don't apply to the submodules.

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

I didn't find any of the existing solutions fitting - simple HTML emails to simple plain text files.

I've opened up this repository, hope it helps someone. MIT license, by the way :)

https://github.com/RobQuistNL/SimpleHtmlToText

Example:

$myHtml = '<b>This is HTML</b><h1>Header</h1><br/><br/>Newlines';
echo (new Parser())->parseString($myHtml);

returns:

**This is HTML**
### Header ###


Newlines

As of Java 7 (and Android API level 19):

System.lineSeparator()

Documentation: Java Platform SE 7

For older versions of Java, use:

System.getProperty("line.separator");

See https://java.sun.com/docs/books/tutorial/essential/environment/sysprop.html for other properties.

To replace multiples columns convert to numpy array using .values:

df.loc[df.A==0, ['B', 'C']] = df.loc[df.A==0, ['B', 'C']].values / 2

For any CSS3-enabled browser you can use an adjacent sibling selector for styling your labels

input:checked + label {
    color: white;
}  

MDN's browser compatibility table says essentially all of the current, popular browsers (Chrome, IE, Firefox, Safari), on both desktop and mobile, are compatible.

You can also try ApexSQL Search – it’s a free SSMS add-in similar to SQL Search.

If you really want to use only SQL you might want to try this script:

select
S.name as [Schema],
o.name as [Object],
o.type_desc as [Object_Type],
C.text as [Object_Definition]
from sys.all_objects O inner join sys.schemas S on O.schema_id = S.schema_id
inner join sys.syscomments C on O.object_id = C.id
where S.schema_id not in (3,4) -- avoid searching in sys and INFORMATION_SCHEMA schemas
and C.text like '%ICE_%'
order by [Schema]

stat appears to do this with the fewest system calls:

I do know that the account needs to have "Log on as a Service" privileges. Other than that, I'm not sure. A quick reference to Log on as a Service can be found here, and there is a lot of information of specific privileges here.

If you mean that you can do this:

CREATE TABLE mytable_d (
ID          TINYINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
Name        VARCHAR(255) NOT NULL,
UNIQUE(Name)
) ENGINE=InnoDB;


ALTER TABLE mytable
ADD COLUMN DID tinyint(5) NOT NULL,
ADD CONSTRAINT mytable_ibfk_4 
      FOREIGN KEY (DID) 
        REFERENCES mytable_d (ID) ON DELETE CASCADE;

 > OK.

But then:

ALTER TABLE mytable
DROP KEY AID ;

gives error.

You can drop the index and create a new one in one ALTER TABLE statement:

ALTER TABLE mytable
DROP KEY AID ,
ADD UNIQUE KEY AID (AID, BID, CID, DID);

I got the error Can't open file for reading. Inappropriate ioctl for device recently when I migrated an old UB2K forum with a DBM file-based database to a new host. Apparently there are multiple, incompatible implementations of DBM. I had a backup of the database, so I was able to load that, but it seems there are other options e.g. moving a perl script/dbm to a new server, and shifting out of dbm?.

Problem

The accepted answer:

const initialState = {
    /* etc */
};

class MyComponent extends Component {
    constructor(props) {
        super(props)
        this.state = initialState;
    }
    reset() {
        this.setState(initialState);
    }
    /* etc */
}

unfortunately is not correct.

initialState is passed as a reference to this.state, so whenever you change state you also change initialState (const doesn't really matter here). The result is that you can never go back to initialState.

Solution

You have to deep copy initialState to state, then it will work. Either write a deep copy function yourself or use some existing module like this.

My problem is cookies are not working "within" the same session. –

Burak: I had the same problem. Enabling cookies fixed the issue.

CookieManager.getInstance().setAcceptCookie(true);

For Bootstrap 3 for collapse, if you don't specify data-target on the anchor and rely on href to determine the target, the event will be prevented. If you use data-target you'll need to prevent the event yourself.

<button type="button" class="btn btn-default" data-toggle="collapse" data-target="#demo">Collapse This</button>

<div id="demo" class="collapse"> 
<p>Lorem ipsum dolor sit amet</p>
</div>

There are padding built into various classes.

For example:

A asp.net web forms app:

<asp:CheckBox ID="chkShowDeletedServers" runat="server" AutoPostBack="True" Text="Show Deleted" />

this code above would place the Text of "Show Deleted" too close to the checkbox to what I see at nice to look at.

However with bootstrap

<div class="checkbox-inline">
    <asp:CheckBox ID="chkShowDeletedServers" runat="server" AutoPostBack="True" Text="Show Deleted" />
</div>

This created the space, if you don't want the text bold, that class=checkbox

Bootstrap is very flexible, so in this case I don't need a hack, but sometimes you need to.

I've had great success with this:

#include <iostream>
#include <windows.h>

int main() {
    ShellExecute(NULL, "open", "path\\to\\file.exe", NULL, NULL, SW_SHOWDEFAULT);
}

If you're interested, the full documentation is here:

http://msdn.microsoft.com/en-us/library/bb762153(VS.85).aspx.

Of course no-one's actually given the correct answer,

num != 0   // num is positive *or* negative!

Quoting from the gcc manual:

For polymorphic classes (classes with virtual functions), the type_info object is written out along with the vtable [...] For all other types, we write out the type_info object when it is used: when applying `typeid' to an expression, throwing an object, or referring to a type in a catch clause or exception specification.

And a bit earlier on the same page:

If the class declares any non-inline, non-pure virtual functions, the first one is chosen as the “key method” for the class, and the vtable is only emitted in the translation unit where the key method is defined.

So, this error happens when the "key method" is missing its definition, as other answers already mentioned.

If you are using anaconda as your python package manager, execute the following:

conda install -c anaconda requests

Installing requests through pip didn't help me.

You can use Len(StrFile) > 0 in loop check statement !

Sub openMyfile()

    Dim Source As String
    Dim StrFile As String

    'do not forget last backslash in source directory.
    Source = "E:\Planning\03\"
    StrFile = Dir(Source)

    Do While Len(StrFile) > 0                        
        Workbooks.Open Filename:=Source & StrFile
        StrFile = Dir()
    Loop
End Sub

Here's a cross platform (Windows / Linux / Mac / Probably others that you can add in the if check) version snippet I made combining information found in this question:

import os
clear = lambda: os.system('cls' if os.name=='nt' else 'clear')
clear()

Same idea but with a spoon of syntactic sugar:

import subprocess   
clear = lambda: subprocess.call('cls||clear', shell=True)
clear()

I know this is an old question but still, I came across a similar problem and i realized that my "not working" css code in my bootstrapOverload.css file was written after the media queries. when I moved it above media queries it started working.

I had to put some the displayed javascripts above inside the "document.ready" code. Otherwise they didn't work. Probably obvious for many, but not for me. So if you're testing look at that option.

<script type="text/javascript">
$(document).ready(function(){
//rest of the javascript code here
});
</script>

I know this is an old post, but I thought the tracking of mouse button using mouse up/down felt a bit clunky, so I found an alternative that may appeal to some.

<style>
    div.myDiv:active {
        cursor: default;
    }
</style>

<script>
    function handleMove( div ) {
        var style = getComputedStyle( div );
        if (style.getPropertyValue('cursor') == 'default')
        {
            // You're down and moving here!
        }
    }
</script>

<div class='myDiv' onmousemove='handleMove(this);'>Click and drag me!</div>

The :active selector handles the mouse click much better than mouse up/down, you just need a way of reading that state in the onmousemove event. For that I needed to cheat and relied on the fact that the default cursor is "auto" and I just change it to "default", which is what auto selects by default.

You can use anything in the object that is returned by getComputedStyle that you can use as a flag without upsetting the look of your page e.g. border-color.

I would have liked to set my own user defined style in the :active section, but I couldn't get that to work. It would be better if it's possible.

Interesting. I got the same problem as you when I wrote a test version.

The solution is to use jquery's ability to chain and do:

$(this).width(500).css("text-align", "center");

Interesting find though.

To expand a bit, the following does not work

$(this).width(500);
$(this).css("text-align", "center");

and results only in the width being set on the style. Chaining the two, as I suggested above, does seem to work.

If you have worked with time/date formatting/parsing in other languages you might have noticed that the other languages use special placeholders for time/date formatting. For eg ruby language uses

%d for day
%Y for year

etc. Golang, instead of using codes such as above, uses date and time format placeholders that look like date and time only. Go uses standard time, which is:

Mon Jan 2 15:04:05 MST 2006  (MST is GMT-0700)
or 
01/02 03:04:05PM '06 -0700

So if you notice Go uses

01 for the day of the month,
02 for the month
03 for hours,
04 for minutes
05 for second
and so on

Therefore for example for parsing 2020-01-29, layout string should be 06-01-02 or 2006-01-02.

You can refer to the full placeholder layout table at this link - https://golangbyexample.com/parse-time-in-golang/

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

You must install middleware to serve the favicon.

I tried this just now:

app.use(express.favicon(path.join(__dirname, 'public','images','favicon.ico'))); 

and got this error message back:

Error: Most middleware (like favicon) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

I think we can take that as being definitive.

Not sure if this is what you mean, but try setting las=1. Here's an example:

require(grDevices)
tN <- table(Ni <- stats::rpois(100, lambda=5))
r <- barplot(tN, col=rainbow(20), las=1)

That represents the style of axis labels. (0=parallel, 1=all horizontal, 2=all perpendicular to axis, 3=all vertical)

The first one will be implemented:

Collection.Where(x => x.Age == 10)
          .Where(x => x.Name == "Fido") // applied to the result of the previous
          .Where(x => x.Fat == true)    // applied to the result of the previous

As opposed to the much simpler (and far fasterpresumably faster):

// all in one fell swoop
Collection.Where(x => x.Age == 10 && x.Name == "Fido" && x.Fat == true)

org.apache.commons.lang3.StringEscapeUtils is now deprecated. You must now use org.apache.commons.text.StringEscapeUtils by

Update Answer (after wwdc 2016):

IOS apps will require secure HTTPS connections by the end of 2016

App Transport Security, or ATS, is a feature that Apple introduced in iOS 9. When ATS is enabled, it forces an app to connect to web services over an HTTPS connection rather than non secure HTTP.

However, developers can still switch ATS off and allow their apps to send data over an HTTP connection as mentioned in above answers. At the end of 2016, Apple will make ATS mandatory for all developers who hope to submit their apps to the App Store. link

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

Used to face the same problem. The reason was in incorrect context passing to AlertDialog.Builder(here). use like AlertDialog.Builder(Homeactivity.this)

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

The language used by Facebook is PHP.

Also, do any other social networking sites use the same language?

The other one I know of is friendster.

Use router.back() directly to go back/route-back programmatic on vue-router.

var myProp = 'prop';
if(myObj.hasOwnProperty(myProp)){
    alert("yes, i have that property");
}

Or

var myProp = 'prop';
if(myProp in myObj){
    alert("yes, i have that property");
}

Or

if('prop' in myObj){
    alert("yes, i have that property");
}

Note that hasOwnProperty doesn't check for inherited properties, whereas in does. For example 'constructor' in myObj is true, but myObj.hasOwnProperty('constructor') is not.

If you call your event handler on markup, as you're doing now, you can't (x-browser). But if you bind the click event with jquery, it's possible the following way:

Markup:

  <a href="#" id="link1" >click</a>

Javascript:

  $(document).ready(function(){
      $("#link1").click(clickWithEvent);  //Bind the click event to the link
  });
  function clickWithEvent(evt){
     myFunc('p1', 'p2', 'p3');
     function myFunc(p1,p2,p3){  //Defined as local function, but has access to evt
        alert(evt.type);        
     }
  }

Since the event ob

Here is combined solution for purging Core Data.

- (void)deleteAllObjectsInCoreData
{
    NSArray *allEntities = self.managedObjectModel.entities;
    for (NSEntityDescription *entityDescription in allEntities)
    {
        NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
        [fetchRequest setEntity:entityDescription];

        fetchRequest.includesPropertyValues = NO;
        fetchRequest.includesSubentities = NO;

        NSError *error;
        NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error];

        if (error) {
                NSLog(@"Error requesting items from Core Data: %@", [error localizedDescription]);
            }

        for (NSManagedObject *managedObject in items) {
            [self.managedObjectContext deleteObject:managedObject];
        }

        if (![self.managedObjectContext save:&error]) {
            NSLog(@"Error deleting %@ - error:%@", entityDescription, [error localizedDescription]);
        }
    }  
}

If you use json_decode($string, true), you will get no objects, but everything as an associative or number indexed array. Way easier to handle, as the stdObject provided by PHP is nothing but a dumb container with public properties, which cannot be extended with your own functionality.

$array = json_decode($string, true);

echo $array['trends'][0]['name'];

For datatables 1.10.12.

$('#table_id').dataTable({
  ajax: function (data, callback, settings) {
    $.ajax({
      url: '/your/url',
      type: 'POST',
      data: data,
      success:function(data){
        callback(data);
        // Do whatever you want.
      }
    });
  }
});

You can do like this:

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    subject.widget.attrs.update({'id' : 'your_id'})

Hope that works.

The OR operator needs a much more complex evaluation process than the IN construct because it allows many conditions, not only equals like IN.

Here is a like of what you can use with OR but that are not compatible with IN: greater. greater or equal, less, less or equal, LIKE and some more like the oracle REGEXP_LIKE. In addition consider that the conditions may not always compare the same value.

For the query optimizer it's easier to to manage the IN operator because is only a construct that defines the OR operator on multiple conditions with = operator on the same value. If you use the OR operator the optimizer may not consider that you're always using the = operator on the same value and, if it doesn't perform a deeper and very much more complex elaboration, it could probably exclude that there may be only = operators for the same values on all the involved conditions, with a consequent preclusion of optimized search methods like the already mentioned binary search.

[EDIT] Probably an optimizer may not implement optimized IN evaluation process, but this doesn't exclude that one time it could happen(with a database version upgrade). So if you use the OR operator that optimized elaboration will not be used in your case.

If you have the .dSYM and the .crash file in the same sub-folder, these are the steps you can take:

1. Looking at the backtrace in the .crash file, note the name of the binary image in the second column, and the address in the third column (e.g. 0x00000001000effdc in the example below).
2. Just under the backtrace, in the "Binary Images" section, note the image name, the architecture (e.g. arm64) and load address (0x1000e4000 in the example below) of the binary image (e.g. TheElements).
3. Execute the following:

$ atos -arch arm64 -o TheElements.app.dSYM/Contents/Resources/DWARF/TheElements -l 0x1000e4000 0x00000001000effdc -[AtomicElementViewController myTransitionDidStop:finished:context:]

You failed to find an app that does this because it is not possible.

The documentation clearly states (here):

Note: You can play back the audio data only to the standard output device. Currently, that is the mobile device speaker or a Bluetooth headset. You cannot play sound files in the conversation audio during a call.

The reason behind this decision has probably something to do with security: there are several scenarios where this capability could be used for cons.

(the OP is highly similar to this, hence I'm basically giving the same answer)

As of 2016, you can do this more simply than in any of the answers already given:

$('#myChosenBox').val();

where "myChosenBox" is the id of the original select input. Or, in the change event:

$('#myChosenBox').on('change', function(e, params) {
    alert(e.target.value); // OR
    alert(this.value); // OR
    alert(params.selected); // also in Panagiotis Kousaris' answer
}

In the Chosen doc, in the section near the bottom of the page on triggering events, it says "Chosen triggers a number of standard and custom events on the original select field." One of those standard events is the change event, so you can use it in the same way as you would with a standard select input. You don't have to mess around with using Chosen's applied classes as selectors if you don't want to. (For the change event, that is. Other events are often a different matter.)

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

For a full discussion of CAST and CONVERT, including the different date formatting options, see the MSDN Library Link below:

The external file is the best and typical bulk-data

The term "bulk data" is related to "a lot of data", so it is natural to use original raw data, with no need to transform it into SQL. Typical raw data files for "bulk insert" are CSV and JSON formats.

Bulk insert with some transformation

In ETL applications and ingestion processes, we need to change the data before inserting it. Temporary table consumes (a lot of) disk space, and it is not the faster way to do it. The PostgreSQL foreign-data wrapper (FDW) is the best choice.

CSV example. Suppose the tablename (x, y, z) on SQL and a CSV file like

fieldname1,fieldname2,fieldname3
etc,etc,etc
... million lines ...

You can use the classic SQL COPY to load (as is original data) into tmp_tablename, them insert filtered data into tablename... But, to avoid disk consumption, the best is to ingested directly by

INSERT INTO tablename (x, y, z)
  SELECT f1(fieldname1), f2(fieldname2), f3(fieldname3) -- the transforms 
  FROM tmp_tablename_fdw
  -- WHERE condictions
;

You need to prepare database for FDW, and instead static tmp_tablename_fdw you can use a function that generates it:

CREATE EXTENSION file_fdw;
CREATE SERVER import FOREIGN DATA WRAPPER file_fdw;
CREATE FOREIGN TABLE tmp_tablename_fdw(
  ...
) SERVER import OPTIONS ( filename '/tmp/pg_io/file.csv', format 'csv');

JSON example. A set of two files, myRawData1.json and Ranger_Policies2.json can be ingested by:

INSERT INTO tablename (fname, metadata, content)
 SELECT fname, meta, j  -- do any data transformation here
 FROM jsonb_read_files('myRawData%.json')
 -- WHERE any_condiction_here
;

where the function jsonb_read_files() reads all files of a folder, defined by a mask:

CREATE or replace FUNCTION jsonb_read_files(
  p_flike text, p_fpath text DEFAULT '/tmp/pg_io/'
) RETURNS TABLE (fid int,  fname text, fmeta jsonb, j jsonb) AS $f$
  WITH t AS (
     SELECT (row_number() OVER ())::int id, 
           f as fname,
           p_fpath ||'/'|| f as f
     FROM pg_ls_dir(p_fpath) t(f)
     WHERE    f like p_flike
  ) SELECT id,  fname,
         to_jsonb( pg_stat_file(f) ) || jsonb_build_object('fpath',p_fpath),
         pg_read_file(f)::jsonb
    FROM t
$f$  LANGUAGE SQL IMMUTABLE;

Lack of gzip streaming

The most frequent method for "file ingestion" (mainlly in Big Data) is preserving original file on gzip format and transfering it with streaming algorithm, anything that can runs fast and without disc consumption in unix pipes:

 gunzip remote_or_local_file.csv.gz | convert_to_sql | psql 

So ideal (future) is a server option for format .csv.gz.

When you call for i in a:, you are getting the actual elements, not the indexes. When we reach the last element, that is 3, b.append(a[i+1]-a[i]) looks for a[4], doesn't find one and then fails. Instead, try iterating over the indexes while stopping just short of the last one, like

for i in range(0, len(a)-1): Do something

Your current code won't work yet for the do something part though ;)

There's a great answer to a post about how to delete local only branches. In it, the fellow builds a command to list out the local branches:

git branch -vv | cut -c 3- | awk '$3 !~/\[/ { print $1 }'

The answer has a great explanation about how this command was derived, so I would suggest you go and read that post.

The overall dimensions of a range are in its Width and Height properties.

Dim r As Range
Set r = ActiveSheet.Range("A4:H12")

Debug.Print r.Width
Debug.Print r.Height

you need to iterate through the array's elements

float foo[] = {1, 2, 3, 10};
int i;
for (i=0;i < (sizeof (foo) /sizeof (foo[0]));i++) {
    printf("%lf\n",foo[i]);
}

or create a function that returns stacked sn printf and then prints it with

printf("%s\n",function_that_makes_pretty_output(foo))

I know this post is older, but haven't seen a solution that provides the actual information, so I want to share what I use for SQL Server 2012 and above. the link below leads to the screenshot showing the information.

First (so no time is wasted):

SQL Server 2000:
SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')

SQL Server 2005+

The "SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')" is not in use anymore. You can see more details on MSFT documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/serverproperty-transact-sql?view=sql-server-2017

SQL Server 2005 - 2008R2 you would have to:

Using PowerShell: https://www.ryadel.com/en/sql-server-retrieve-product-key-from-an-existing-installation/

Using TSQL (you would need to know the registry key path off hand): https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-server-registry-transact-sql?view=sql-server-2017

SQL Server 2012+

Now, you can extract SQL Server Licensing information from the SQL Server Error Log, granted it may not be formatted the way you want, but the information is there and can be parsed, along with more descriptive information that you probably didn't expect.

EXEC sp_readerrorlog @p1 = 0
                    ,@p2 = 1
                    ,@p3 = N'licensing'

NOTE: I tried pasting the image directly, but since I am new at stakoverflow we have to follow the link below.

SQL Server License information via sp_readerrorlog

So, over SMTP when a message is submitted, the SMTP envelope (sender, recipients, etc.) is different from the actual data of the message.

The Sender header is used to identify in the message who submitted it. This is usually the same as the From header, which is who the message is from. However, it can differ in some cases where a mail agent is sending messages on behalf of someone else.

The Return-Path header is used to indicate to the recipient (or receiving MTA) where non-delivery receipts are to be sent.

For example, take a server that allows users to send mail from a web page. So, [email protected] types in a message and submits it. The server then sends the message to its recipient with From set to [email protected]. The actual SMTP submission uses different credentials, something like [email protected]. So, the sender header is set to [email protected], to indicate the From header doesn't indicate who actually submitted the message.

In this case, if the message cannot be sent, it's probably better for the agent to receive the non-delivery report, and so Return-Path would also be set to [email protected] so that any delivery reports go to it instead of the sender.

If you are doing just that, a form submission to send e-mail, then this is probably a direct parallel with how you'd set the headers.

if you want just the parts of url after http://domain.com, try this:

<?php echo $_SERVER['REQUEST_URI']; ?>

if the current url was http://domain.com/some-slug/some-id, echo will return only '/some-slug/some-id'.

if you want the full url, try this:

<?php echo 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>

I am assuming that you are making a quiz kind of application. For this kind of application I have written a function which is as follows:

def shuffle(q):
"""
The input of the function will 
be the dictionary of the question
and answers. The output will
be a random question with answer
"""
selected_keys = []
i = 0
while i < len(q):
    current_selection = random.choice(q.keys())
    if current_selection not in selected_keys:
        selected_keys.append(current_selection)
        i = i+1
        print(current_selection+'? '+str(q[current_selection]))

If I will give the input of questions = {'VENEZUELA':'CARACAS', 'CANADA':'TORONTO'} and call the function shuffle(questions) Then the output will be as follows:

VENEZUELA? CARACAS
CANADA? TORONTO

You can extend this further more by shuffling the options also

total count the documents where the value of the field is not equal to the specified value.

async function getRegisterUser() {
    return Login.count({"role": { $ne: 'Super Admin' }}, (err, totResUser) => {
        if (err) {
            return err;
        }
        return totResUser;
    })
}

If you specifically want to use an ad hoc wireless network, then Andy's answer seems to be your only option. However, if you just want to share your laptop's internet connection via Wi-fi using any means necessary, then you have at least two more options:

1. Use your laptop as a router to create a wifi hotspot using Virtual Router or Connectify. A nice set of instructions can be found here.
2. Use the Wi-fi Direct protocol which creates a direct connection between any devices that support it, although with Android devices support is limited* and with Windows the feature seems likely to be Windows 8 only.

*Some phones with Android 2.3 have proprietary OS extensions that enable Wi-fi Direct (mostly newer Samsung phones), but Android 4 should fully support this (source).

Try with this one:

result = re.search(r"\w+( )\w+", text)

This won't help you step through code or break on errors, but it's a useful way to get the same debug console for your project on all browsers.

myLog = function() {
    if (!myLog._div) { myLog.createDiv(); }

    var logEntry = document.createElement('span');
    for (var i=0; i < arguments.length; i++) {
        logEntry.innerHTML += myLog.toJson(arguments[i]) + '<br />';
    }
    logEntry.innerHTML += '<br />';

    myLog._div.appendChild(logEntry);
}
myLog.createDiv = function() {
    myLog._div = document.body.appendChild(document.createElement('div'));
    var props = {
        position:'absolute', top:'10px', right:'10px', background:'#333', border:'5px solid #333', 
        color: 'white', width: '400px', height: '300px', overflow: 'auto', fontFamily: 'courier new',
        fontSize: '11px', whiteSpace: 'nowrap'
    }
    for (var key in props) { myLog._div.style[key] = props[key]; }
}
myLog.toJSON = function(obj) {
    if (typeof window.uneval == 'function') { return uneval(obj); }
    if (typeof obj == 'object') {
        if (!obj) { return 'null'; }
        var list = [];
        if (obj instanceof Array) {
            for (var i=0;i < obj.length;i++) { list.push(this.toJson(obj[i])); }
            return '[' + list.join(',') + ']';
        } else {
            for (var prop in obj) { list.push('"' + prop + '":' + this.toJson(obj[prop])); }
            return '{' + list.join(',') + '}';
        }
    } else if (typeof obj == 'string') {
        return '"' + obj.replace(/(["'])/g, '\\$1') + '"';
    } else {
        return new String(obj);
    }
}

myLog('log statement');
myLog('logging an object', { name: 'Marcus', likes: 'js' });

This is put together pretty hastily and is a bit sloppy, but it's useful nonetheless and can be improved easily!

A simple way is to write:

-std=c++11

in the Other Options section of the compiler flags. You could do this on a per-project basis (Project -> Build Options), and/or set it as a default option in the Settings -> Compilers part.

Some projects may require -std=gnu++11 which is like C++11 but has some GNU extensions enabled.

If using g++ 4.9, you can use -std=c++14 or -std=gnu++14.

I ran into the same issue trying to install Dropbox SDK.

CURL was indeed enabled on my system but this meant by the php.ini in the wamp\bin\apache folder.

I simply had to manually edit the php.ini situated in wamp\bin\php, uncomment the extension=php_curl.dll line, restart Wamp and it worked perfectly.

Why there are those 2 php.ini and only one is used is still a mystery for me...

Hope it's helpul to someone!

You can't directly instantiate an abstract class, but you can create an anonymous class when there is no concrete class:

public class AbstractTest {
    public static void main(final String... args) {
        final Printer p = new Printer() {
            void printSomethingOther() {
                System.out.println("other");
            }
            @Override
            public void print() {
                super.print();
                System.out.println("world");
                printSomethingOther(); // works fine
            }
        };
        p.print();
        //p.printSomethingOther(); // does not work
    }
}

abstract class Printer {
    public void print() {
        System.out.println("hello");
    }
}

This works with interfaces, too.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

Actually firstOrCreate would not update in case that the register already exists in the DB. I improved a bit Erik's solution as I actually needed to update a table that has unique values not only for the column "id"

/**
 * If the register exists in the table, it updates it. 
 * Otherwise it creates it
 * @param array $data Data to Insert/Update
 * @param array $keys Keys to check for in the table
 * @return Object
 */
static function createOrUpdate($data, $keys) {
    $record = self::where($keys)->first();
    if (is_null($record)) {
        return self::create($data);
    } else {
        return self::where($keys)->update($data);
    }
}

Then you'd use it like this:

Model::createOrUpdate(
        array(
    'id_a' => 1,
    'foo' => 'bar'
        ), array(
    'id_a' => 1
        )
);

Using Stack, here are the steps to follow: Push the first vertex on the stack then,

1. If possible, visit an adjacent unvisited vertex, mark it, and push it on the stack.
2. If you can’t follow step 1, then, if possible, pop a vertex off the stack.
3. If you can’t follow step 1 or step 2, you’re done.

Here's the Java program following the above steps:

public void searchDepthFirst() {
    // begin at vertex 0
    vertexList[0].wasVisited = true;
    displayVertex(0);
    stack.push(0);
    while (!stack.isEmpty()) {
        int adjacentVertex = getAdjacentUnvisitedVertex(stack.peek());
        // if no such vertex
        if (adjacentVertex == -1) {
            stack.pop();
        } else {
            vertexList[adjacentVertex].wasVisited = true;
            // Do something
            stack.push(adjacentVertex);
        }
    }
    // stack is empty, so we're done, reset flags
    for (int j = 0; j < nVerts; j++)
            vertexList[j].wasVisited = false;
}

The easiest way is to use Math library.

Use Math.pow(a, b) and the result will be a^b

If you want to do it yourself, you have to use for-loop

// Works only for b >= 1
public static double myPow(double a, int b){
    double res =1;
    for (int i = 0; i < b; i++) {
        res *= a;
    }
    return res;
}

Using:

double base = 2;
int exp = 3;
double whatIWantToKnow = myPow(2, 3);

My situation was something akin to:

switch (text) {
  case SOME_CONSTANT || ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT || FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

The default case always entered. If you're running into a similar multi-case switch statement issue, you're looking for this:

switch (text) {
  case SOME_CONSTANT:
  case ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT:
  case FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

Use public_path()

For reference:

// Path to the project's root folder    
echo base_path();

// Path to the 'app' folder    
echo app_path();        

// Path to the 'public' folder    
echo public_path();

// Path to the 'storage' folder    
echo storage_path();

// Path to the 'storage/app' folder    
echo storage_path('app');

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

You should note that div tag behaves like nothing and just let you to put something in it. It means that if you insert a paragraph with 100 lines of text within a div tag, it shows all the text but its height won't change to contain all the text.

So you have to use a CSS & HTML trick to handle this issue. This trick is very simple. you must use an empty div tag with class="clear" and then you will have to add this class to your CSS. Also note that your have #wrap in your CSS file but you don't have any tag with this id. In summary you have to change you code to something like below:

HTML Code:

    <!-- Change "id" from "container" to "wrap" -->
    <div id="wrap">    
        <div id="header">
        </div>

        <div id="navigation"> 
            <a href="/" class="navigation">home</a>
            <a href="about.php" class="navigation">about</a>
            <a href="fanlisting.php" class="navigation">fanlisting</a>
            <a href="reasons.php" class="navigation">100 reasons</a>
            <a href="letter.php" class="navigation">letter</a>
        </div>
        <div id="content" >
            <h1>Update Information</h1>
            <iframe name="frame" id="frame" src="http://website.org/update.php" allowtransparency="true" frameborder="0"></iframe>

            <!-- Add this line -->
            <div class="clear"></div>
        </div>
        <div id="footer">
        </div>

        <!-- Add this line -->
        <div class="clear"></div>
    </div>

And also add this line to your CSS file:

.clear{ display: block; clear: both;}

You can import the lib org.apache.commons.lang.ArrayUtils

There is a static method where you can pass in an int array and a value to check for.

contains(int[] array, int valueToFind) Checks if the value is in the given array.

ArrayUtils.contains(intArray, valueToFind);

ArrayUtils API

If you want listen an event (i.e OnClick) on an input with "demo" id, you can use:

new Vue({
  el: '#demo',
  data: {
    n: 0
  },
  methods: {
   onClick: function (e) {
     console.log(e.target.tagName) // "A"
     console.log(e.targetVM === this) // true
  }
 }
})

var link = $("#me").closest(":has(h3 span b)").find('h3 span b');

Example: http://jsfiddle.net/e27r8/

This uses the closest()^[docs] method to get the first ancestor that has a nested h3 span b, then does a .find().

Of course you could have multiple matches.

Otherwise, you're looking at doing a more direct traversal.

var link = $("#me").closest("h3 + div").prev().find('span b');

edit: This one works with your updated HTML.

Example: http://jsfiddle.net/e27r8/2/

EDIT: Updated to deal with updated question.

var link = $("#me").closest("h3 + *").prev().find('span b');

This makes the targeted element for .closest() generic, so that even if there is no parent, it will still work.

Example: http://jsfiddle.net/e27r8/4/

My vote would be for Conditional

[Conditional("DEBUG")]
public void DebugOnlyFunction()
{
    // your code here
}

You can use this to add a function with advanced debugging features; like Debug.Write, it is only called in debug builds, and so allows you to encapsulate complex debug logic outside the main flow of your program.

window.top.location.href = "http://example.com";

window.top refers to the window object of the page at the top of the frames hierarchy.

It's the end statement for the alternative syntax:

foreach ($foo as $bar) :
    ...
endforeach;

Useful to make code more readable if you're breaking out of PHP:

<?php foreach ($foo as $bar) : ?>
    <div ...>
        ...
    </div>
<?php endforeach; ?>

Selectors are an efficient way to reference methods directly in compiled code - the compiler is what actually assigns the value to a SEL.

Other have already covered the second part of your q, the ':' at the end matches a different signature than what you're looking for (in this case that signature doesn't exist).

Modal Popups in Interface Builder (Storyboards)

Step 1

On the ViewController you want as your modal popup, make the background color of the root UIView clear. Tip: Do not use the root UIView as your popup. Add a new UIView that is smaller to be your popup.

Step 2

Create a Segue to the ViewController that has your popup. Select "Present Modally".

Two Methods To Create Popup From Here

Method One - Using the Segue

Select the Segue and change Presentation to "Over Current Context":

Method Two - Using the View Controller

Select the ViewController Scene that is your popup. In Attributes Inspector, under View Controller section, set Presentation to "Over Current Context":

Either method will work. That should do it!

You can convert String to Timestamp:

String inDate = "01-01-1990"
DateFormat df = new SimpleDateFormat("MM-dd-yyyy");
Timestamp ts = new Timestamp(((java.util.Date)df.parse(inDate)).getTime());

You can do the entire conversion in one line, using the following code:

String number = "1000500000.574";
String convertedString = new DecimalFormat("#,###.##").format(Double.parseDouble(number));

The last two # signs in the DecimalFormat constructor can also be 0s. Either way works.

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage2.Master" AutoEventWireup="true" CodeBehind="History.aspx.cs" Inherits="NAMESPACE_Web.History1" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
    <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>


 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> 

        <script type="text/javascript">

            function helloFromCodeBehind() {
                alert("hello!")
            }


        </script>

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

 <div id="container"  ></div>

</asp:Content>

Code Behind

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace NAMESPACE_Web
{
    public partial class History1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

            ScriptManager.RegisterStartupScript(this, GetType(), "displayalertmessage", "helloFromCodeBehind()", true);
        }

    }
}

Possible pitfalls:-

1. Code and HTML might not be in same namespace
2. CodeBehind="History.aspx.cs" is pointing to wrong page
3. JS function is having some error

To use uint8_t type alias, you have to include stdint.h standard header.

It is also possible with Java 8 streams:

int[] a = IntStream.generate(() -> value).limit(count).toArray();

Probably, not the most efficient way to do the job, however.

To clear things up a little, since some of the answers are providing incorrect information:

The jQuery .css() method allows the use of either DOM or CSS notation in many cases. So, both backgroundColor and background-color will get the job done.

Additionally, when you call .css() with arguments you have two choices as to what the arguments can be. They can either be 2 comma separated strings representing a css property and its value, or it can be a Javascript object containing one or more key value pairs of CSS properties and values.

In conclusion the only thing wrong with your code is a missing }. The line should read:

$("#myParagraph").css({"backgroundColor":"black","color":"white"});

You cannot leave the curly brackets out, but you may leave the quotes out from around backgroundColor and color. If you use background-color you must put quotes around it because of the hyphen.

In general, it's a good habit to quote your Javascript objects, since problems can arise if you do not quote an existing keyword.

A final note is that about the jQuery .ready() method

$(handler);

is synonymous with:

$(document).ready(handler);

as well as with a third not recommended form.

This means that $(init) is completely correct, since init is the handler in that instance. So, init will be fired when the DOM is constructed.

Actually jessehouwing gave the solution for normal scenario.

But in my case I have enabled 2 types of session in my web.config file

It's like below.

First one :

<modules runAllManagedModulesForAllRequests="true">
        <remove name="Session" />
        <add name="Session" type="System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>

Second one :

<sessionState mode="Custom" customProvider="DefaultSessionProvider">
            <providers>
                <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="PawLoyalty" applicationName="PawLoyalty"/>
            </providers>
 </sessionState>

So in my case I have to comment Second one.B'cos that thing for the production.When I commented out second one my problem vanished.

Check the config file, the config path is /etc/php5/fpm/pool.d/www.conf, there you'll find the path by config and if you want you can change it.

EDIT:
well you're correct, you need to replace listen = 127.0.0.1:9000 to listen = /var/run/php5-fpm/php5-fpm.sock, then you need to run sudo service php5-fpm restart, and make sure it says that it restarted correctly, if not then make sure that /var/run/ has a folder called php5-fpm, or make it listen to /var/run/php5-fpm.sock cause i don't think the folder inside /var/run is created automatically, i remember i had to edit the start up script to create that folder, otherwise even if you mkdir /var/run/php5-fpm after restart that folder will disappear and the service starting will fail.

Well Curl could be a better option for json representation but in that case it would be difficult to understand the structure of json because its in command line. if you want to get your json on browser you simply remove all the XML Annotations like -

@XmlRootElement(name="person")
@XmlAccessorType(XmlAccessType.NONE)
@XmlAttribute
@XmlElement

from your model class and than run the same url, you have used for xml representation.

Make sure that you have jacson-databind dependency in your pom.xml

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.4.1</version>
</dependency>

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

Using prepared statements with parametrised values is not simply another way to dynamically create a string of SQL. You create a prepared statement at the database, and then send the parameter values alone.

So what is probably sent to the database will be a PREPARE ..., then SET ... and finally EXECUTE ....

You won't be able to get some SQL string like SELECT * FROM ..., even if it would produce equivalent results, because no such query was ever actually sent to the database.

This article is a great way to start.

Also, you need to create test cases in which you read first 10k(or something else, but shouldn't be too small) lines and calculate the reading times accordingly.

Threading might be a good way to go, but it's important that we know what you will be doing with the data.

Another thing to be considered is, how you will store that size of data.

The error says "The index is out of range". That means you were trying to index an object with a value that was not valid. If you have two books, and I ask you to give me your third book, you will look at me funny. This is the computer looking at you funny. You said - "create a collection". So it did. But initially the collection is empty: not only is there nothing in it - it has no space to hold anything. "It has no hands".

Then you said "the first element of the collection is now 'ItemID'". And the computer says "I never was asked to create space for a 'first item'." I have no hands to hold this item you are giving me.

In terms of your code, you created a view, but never specified the size. You need a

dataGridView1.ColumnCount = 5;

Before trying to access any columns. Modify

DataGridView dataGridView1 = new DataGridView();

dataGridView1.Columns[0].Name = "ItemID";

to

DataGridView dataGridView1 = new DataGridView();
dataGridView1.ColumnCount = 5;
dataGridView1.Columns[0].Name = "ItemID";

See http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columncount.aspx

You're looking for the .filter() function:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  });

That'll produce an array that contains only those objects whose "selected" property is true (or truthy).

edit sorry I was getting some coffee and I missed the comments - yes, as jAndy noted in a comment, to filter and then pluck out just the "id" values, it'd be:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  }).map(function(obj) { return obj.id; });

Some functional libraries (like Functional, which in my opinion doesn't get enough love) have a .pluck() function to extract property values from a list of objects, but native JavaScript has a pretty lean set of such tools.

I had the same problem on Windows 7 64-bit Pro. I adjusted network adapters binding using Control panel but nothing changed. Also metrics where showing that Win should use Ethernet adapter as primary, but it didn't.

Then a tried to uninstall Ethernet adapter driver and then install it again (without restart) and then I checked metrics for sure.

After this, Windows started prioritize Ethernet adapter.

You missed this step in the installation process.

Install the Flutter and Dart plugins:

• Start Android Studio.
• Open plugin preferences (File → Settings → Plugins on Windows & Linux OR Preferences → Plugins on macOS).
• Select Browse repositories, select the Flutter plugin and click Install.
• Click Yes when prompted to install the Dart plugin.
• Click Restart when prompted.

If are using Visual Studio Code, to Install the Flutter and Dart plugins:

• Start VS Code.
• Invoke View → Command Palette.
• Type install, and select Extensions: Install Extensions.
• Type flutter in the extensions search field, select Flutter in the list, and click Install. This also installs the required Dart plugin.
• Validate your setup with the Flutter Doctor
• Invoke View → Command Palette….
• Type doctor, and select the Flutter: Run Flutter Doctor.

Review the output in the OUTPUT pane for any issues.

If you are using IPython, then you need to type "foo??"

In [19]: foo??
Signature: foo(arg1, arg2)
Source:
def foo(arg1,arg2):
    #do something with args
    a = arg1 + arg2
    return a

File:      ~/Desktop/<ipython-input-18-3174e3126506>
Type:      function

None of the configuration above worked for me on my CentOS 7 server. After hours of searching, that what worked for me:

Edit file phpMyAdmin.conf

sudo nano /etc/httpd/conf.d/phpMyAdmin.conf

And replace the existing <Directory> ... </Directory> node with the following:

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
       Require all granted
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     Deny from All
     Allow from 127.0.0.1
     Allow from ::1
   </IfModule>
</Directory>

Try this.

To get the data from the UserDefaults.

var defaults = NSUserDefaults.standardUserDefaults()
var dict : NSDictionary = ["key":"value"]
var array1: NSArray = dict.allValues // Create a dictionary and assign that to this array
defaults.setObject(array1, forkey : "MyKey")

var myarray : NSArray = defaults.objectForKey("MyKey") as NSArray
println(myarray)

This will also work

SELECT NAME 
FROM GEO_LOCATION
WHERE MODIFY_ON BETWEEN SYSDATE() - INTERVAL 2 HOUR AND SYSDATE()

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Hope it helps!

I know this is an old post, but for the newbies like myself who still hit this page this might be useful. when you hover on a method you get a non clickable info-box whereas if you just write a comma in the method parenthesis the IntelliSense will offer you the beloved info-box with the clickable arrows.

This is actually very simple. It is much easier to find unique values, if the values are sorted first:

function sort_unique(arr) {
  if (arr.length === 0) return arr;
  arr = arr.sort(function (a, b) { return a*1 - b*1; });
  var ret = [arr[0]];
  for (var i = 1; i < arr.length; i++) { //Start loop at 1: arr[0] can never be a duplicate
    if (arr[i-1] !== arr[i]) {
      ret.push(arr[i]);
    }
  }
  return ret;
}
console.log(sort_unique(['237','124','255','124','366','255']));
//["124", "237", "255", "366"]

If we wanted to return the same matrix we would write:

return [[ m[row][col] for col in range(0,width) ] for row in range(0,height) ]

What this does is it iterates over a matrix m by going through each row and returning each element in each column. So the order would be like:

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

Now for question 3, we instead want to go column by column, returning each element in each row. So the order would be like:

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

Therefore just switch the order in which we iterate:

return [[ m[row][col] for row in range(0,height) ] for col in range(0,width) ]

It works even without using 'export' keyword. This is what i have in my setenv.sh (/usr/share/tomcat7/bin/setenv.sh) and it works.

Are you sure you need a list in this case? If you are populating the list with many items, performance will suffer with myList.Contains or myList.Any; the run-time will be quadratic. You might want to consider using a better data structure. For example,

 public class MyClass
    {
        public string Property1 { get; set; }
        public string Property2 { get; set; }

    }

    public class MyClassComparer : EqualityComparer<MyClass>
    {
        public override bool Equals(MyClass x, MyClass y)
        {
            if(x == null || y == null)
               return x == y;

            return x.Property1 == y.Property1 && x.Property2 == y.Property2;
        }

        public override int GetHashCode(MyClass obj)
        {
            return obj == null ? 0 : (obj.Property1.GetHashCode() ^ obj.Property2.GetHashCode());
        }
    }

You could use a HashSet in the following manner:

  var set = new HashSet<MyClass>(new MyClassComparer());
  foreach(var myClass in ...)
     set.Add(myClass);

Of course, if this definition of equality for MyClass is 'universal', you needn't write an IEqualityComparer implementation; you could just override GetHashCode and Equals in the class itself.

If it's not obvious after all the answers you can also output to a completely different directories (for example a directory outside your standard dist folder). You can do that by using your root as a path (because you only have one path) and by moving the full "directory part" of your path to the entry option (because you can have multiple entries):

entry: {
  'dist/main': './src/index.js',
  'docs/main': './src/index.js'
},
output: {
  filename: '[name].js',
  path: path.resolve(__dirname, './'),
}

This config results in the ./dist/main.js and ./docs/main.js being created.

def evenly(l, n):
    len_ = len(l)
    split_size = len_ // n
    split_size = n if not split_size else split_size
    offsets = [i for i in range(0, len_, split_size)]
    return [l[offset:offset + split_size] for offset in offsets]

Example:

l = [a for a in range(97)] should be consist of 10 parts, each have 9 elements except the last one.

Output:

[[0, 1, 2, 3, 4, 5, 6, 7, 8],
 [9, 10, 11, 12, 13, 14, 15, 16, 17],
 [18, 19, 20, 21, 22, 23, 24, 25, 26],
 [27, 28, 29, 30, 31, 32, 33, 34, 35],
 [36, 37, 38, 39, 40, 41, 42, 43, 44],
 [45, 46, 47, 48, 49, 50, 51, 52, 53],
 [54, 55, 56, 57, 58, 59, 60, 61, 62],
 [63, 64, 65, 66, 67, 68, 69, 70, 71],
 [72, 73, 74, 75, 76, 77, 78, 79, 80],
 [81, 82, 83, 84, 85, 86, 87, 88, 89],
 [90, 91, 92, 93, 94, 95, 96]]

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

Replace 

<a href="http://www.foracure.org.au" target="_blank"></a>    

with 

<a href="#" onclick='window.open("http://www.foracure.org.au");return false;'></a>

in your code and will work in Chrome and other browsers.

Thanks Anurag

I believe the reason there's no straightforward property to access the selected row of a WPF DataGrid is because a DataGrid's selection mode can be set to either the row-level or the cell-level. Therefore, the selection-related properties and events are all written against cell-level selection - you'll always have selected cells regardless of the grid's selection mode, but you aren't guaranteed to have a selected row.

I don't know precisely what you're trying to achieve by handling the CellEditEnding event, but to get the values of all selected cells when you select a row, take a look at handling the SelectedCellsChanged event, instead. Especially note the remarks in that article:

You can handle the SelectedCellsChanged event to be notified when the collection of selected cells is changed. If the selection includes full rows, the Selector.SelectionChanged event is also raised.

You can retrieve the AddedCells and RemovedCells from the SelectedCellsChangedEventArgs in the event handler.

Hope that helps put you on the right track. :)

Since Java 8, using the streams API:

int[][] copy = Arrays.stream(matrix).map(int[]::clone).toArray(int[][]::new);

For any number validation you have to use different different range validation as per your requirements :

For Integer

[Range(0, int.MaxValue, ErrorMessage = "Please enter valid integer Number")]

for float

[Range(0, float.MaxValue, ErrorMessage = "Please enter valid float Number")]

for double

[Range(0, double.MaxValue, ErrorMessage = "Please enter valid doubleNumber")]

You can use the LocalDateTime class from Java 8. For eg :

long n = 4;
LocalDateTime localDateTime = LocalDateTime.now();
System.out.println(localDateTime.plusHours(n));

1. Open Developer Command prompt.
2. type

where gacutil

Now you can use https://sites.google.com

Build internal project hubs, team sites, public-facing websites, and more—all without designer, programmer, or IT help. With the new Google Sites, building websites is easy. Just drag content where you need it.

here is a solution:

Bitmap bitmap = BitmapFactory.decodeFile(filePath);

I use to ZipDiff lib (have both Java and ant API).

I'm not sure that there is any option for simply printing the full effective search path.

But: the search path consists of directories specified by -L options on the command line, followed by directories added to the search path by SEARCH_DIR("...") directives in the linker script(s). So you can work it out if you can see both of those, which you can do as follows:

If you're invoking ld directly:

• The -L options are whatever you've said they are.
• To see the linker script, add the --verbose option. Look for the SEARCH_DIR("...") directives, usually near the top of the output. (Note that these are not necessarily the same for every invocation of ld -- the linker has a number of different built-in default linker scripts, and chooses between them based on various other linker options.)

If you're linking via gcc:

• You can pass the -v option to gcc so that it shows you how it invokes the linker. In fact, it normally does not invoke ld directly, but indirectly via a tool called collect2 (which lives in one of its internal directories), which in turn invokes ld. That will show you what -L options are being used.
• You can add -Wl,--verbose to the gcc options to make it pass --verbose through to the linker, to see the linker script as described above.

If you're just interested in increasing the font size of just the first paragraph of any document, an effect used by online publications, then you can use the first-child pseudo-class to achieve the desired effect.

p:first-child
{
   font-size:   115%; // Will set the font size to be 115% of the original font-size for the p element.
}

However, this will change the font size of every p element that is the first-child of any other element. If you're interested in setting the size of the first p element of the body element, then use the following:

body > p:first-child
{
   font-size:   115%;
}

The above code will only work with the p element that is a child of the body element.

You can use the ui object provided to the events, specifically you want the stop event, the ui.item property and .index(), like this:

$("#sortable").sortable({
    stop: function(event, ui) {
        alert("New position: " + ui.item.index());
    }
});

You can see a working demo here, remember the .index() value is zero-based, so you may want to +1 for display purposes.

You could have used DISTINCT or just remove the PARTITION BY portions and use GROUP BY:

SELECT BrandId
       ,SUM(ICount)
       ,TotalICount = SUM(ICount) OVER ()    
       ,Percentage = SUM(ICount) OVER ()*1.0 / SUM(ICount) 
FROM Table 
WHERE DateId  = 20130618
GROUP BY BrandID

Not sure why you are dividing the total by the count per BrandID, if that's a mistake and you want percent of total then reverse those bits above to:

SELECT BrandId
           ,SUM(ICount)
           ,TotalICount = SUM(ICount) OVER ()    
           ,Percentage = SUM(ICount)*1.0 / SUM(ICount) OVER () 
    FROM Table 
    WHERE DateId  = 20130618
    GROUP BY BrandID

For me, I had an empty tag NuGetPackageImportStamp in .csproj

<NuGetPackageImportStamp>
    </NuGetPackageImportStamp>

It should ideally contain some valid GUID.

Removing this tag and then "Restore Nugets" worked for me.

If you are copy-pasting code into R, it sometimes won't accept some special characters such as "~" and will appear instead as a "?". So if a certain character is giving an error, make sure to use your keyboard to enter the character, or find another website to copy-paste from if that doesn't work.

const char* one = "one";
const char* two = "two";
char result[40];
sprintf(result, "%s%s", one, two);

Try replacing the appropriate lines with:

myStringArray[0][x-1] = "a string";
myStringArray[0][y-1] = "another string";

Your code is incorrect because the sub-arrays have a length of y, and indexing starts at 0. So setting to myStringArray[0][y] or myStringArray[0][x] will fail because the indices x and y are out of bounds.

String[][] myStringArray = new String [x][y]; is the correct way to initialise a rectangular multidimensional array. If you want it to be jagged (each sub-array potentially has a different length) then you can use code similar to this answer. Note however that John's assertion that you have to create the sub-arrays manually is incorrect in the case where you want a perfectly rectangular multidimensional array.

I agree with Keith, but I can't vote up (yet).

I use a static method and swith statement to return exactly what I want. In the database I store tinyint and my code only uses the actual enum, so the strings are for UI requirements. After numerous testing this resulted in the best performance and most control over the output.

public static string ToSimpleString(this enum)
{
     switch (enum)
     {
         case ComplexForms:
             return "ComplexForms";
             break;
     }
}

public static string ToFormattedString(this enum)
{
     switch (enum)
     {
         case ComplexForms:
             return "Complex Forms";
             break;
     }
}

However, by some accounts, this leads to a possible maintenance nightmare and some code smell. I try to keep an eye for enums that are long and a lot of enums, or those that change frequently. Otherwise, this has been a great solution for me.

As the default configuration of Postgres, a user called postgres is made and the user postgres has full super admin access to entire PostgreSQL instance running on your OS.

sudo -u postgres psql

The above command gets you the psql command line interface in admin mode.

Creating user

sudo -u postgres createuser <username>

Creating Database

 sudo -u postgres createdb <dbname>

NOTE: < > are not to be used while writing command, they are used just to signify the variables

Try this:

class Flonetwork(Object):
    def __init__(self,adj = {},flow={}):
        self.adj = adj
        self.flow = flow

Use this:

return RedirectToAction("LogIn", "Account", new { area = "" });

This will redirect to the LogIn action in the Account controller in the "global" area.

It's using this RedirectToAction overload:

protected internal RedirectToRouteResult RedirectToAction(
    string actionName,
    string controllerName,
    Object routeValues
)

Use scp priv_key.pem source user@host:target if you need to connect using a private key.

or if using pscp then use pscp -i priv_key.ppk source user@host:target

try using

View view_instance = (View)findViewById(R.id.nutrition_bar_filled);
view_instance.setWidth(10);

use Layoutparams to do so where you can set width and height like below.

LayoutParams lp = new LayoutParams(10,LayoutParams.wrap_content);
View_instance.setLayoutParams(lp);

I sort of agree with leander on this one.

           ...
        }

        @Override
        protected void onPostExecute(ArrayList<String> result) {
           ... //do something with the result list here
        }
}

Or you could just make the result list a class parameter and replace the ArrayList with a boolean (success/failure);

public class calc_stanica extends AsyncTask<String, Void, Boolean> {
        private List<String> resultList;

        @Override
        protected boolean doInBackground(String... args) {
           ...
        }

        @Override
        protected void onPostExecute(boolean success) {
           ... //if successfull, do something with the result list here
        }
}

The following approach seems simple and can be used with variables of different size:

import hickle as hkl
# write variables to filename [a,b,c can be of any size]
hkl.dump([a,b,c], filename)

# load variables from filename
a,b,c = hkl.load(filename)

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

A. Wolff was leading you in the right direction. There are several attributes where you should not be setting a string value. You must toggle it with a boolean true or false.

.attr("hidden", false) will remove the attribute the same as using .removeAttr("hidden").

.attr("hidden", "false") is incorrect and the tag remains hidden.

You should not be setting hidden, checked, selected, or several others to any string value to toggle it.

Also, in .NET 4 this is even easier if you use the dynamic keyword:

dynamic document = this.browser.Document;
dynamic head = document.GetElementsByTagName("head")[0];
dynamic scriptEl = document.CreateElement("script");
scriptEl.text = ...;
head.AppendChild(scriptEl);

If you have MySQL installed through Homebrew these commands will help you:

# For starting
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

# For stoping
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

DECLARE @nombre NVARCHAR(100)
DECLARE @tablas TABLE(nombre nvarchar(100))

INSERT INTO @tablas
SELECT t.TABLE_SCHEMA+ '.'+t.TABLE_NAME FROM INFORMATION_SCHEMA.TABLES T
DECLARE @contador INT=0

SELECT @contador=COUNT(*) FROM INFORMATION_SCHEMA.TABLES

WHILE @contador>0 
BEGIN
    SELECT TOP 1 @nombre=nombre FROM @tablas 
    DECLARE @sql NVARCHAR(500)=''
    SET @sql =@sql+'Truncate table  '+@nombre
    EXEC (@sql)
    SELECT @sql
    SET @contador=@contador-1   
    DELETE TOP (1) @tablas 
END

You can think of the static methods and non-static methods of a class as being different interfaces. When called, static methods resolve to the singleton static class object, and non-static methods resolve to the instance of the class you deal with. So, if you use static and non-static methods in an interface, you'd effectively be declaring two interfaces when really we want interfaces to be used to access one cohesive thing.

The python seaborn module is based on matplotlib, and produces a very nice heatmap.

Below is an implementation with seaborn, designed for the ipython/jupyter notebook.

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib inline
# import the data directly into a pandas dataframe
nba = pd.read_csv("http://datasets.flowingdata.com/ppg2008.csv", index_col='Name  ')
# remove index title
nba.index.name = ""
# normalize data columns
nba_norm = (nba - nba.mean()) / (nba.max() - nba.min())
# relabel columns
labels = ['Games', 'Minutes', 'Points', 'Field goals made', 'Field goal attempts', 'Field goal percentage', 'Free throws made', 
          'Free throws attempts', 'Free throws percentage','Three-pointers made', 'Three-point attempt', 'Three-point percentage', 
          'Offensive rebounds', 'Defensive rebounds', 'Total rebounds', 'Assists', 'Steals', 'Blocks', 'Turnover', 'Personal foul']
nba_norm.columns = labels
# set appropriate font and dpi
sns.set(font_scale=1.2)
sns.set_style({"savefig.dpi": 100})
# plot it out
ax = sns.heatmap(nba_norm, cmap=plt.cm.Blues, linewidths=.1)
# set the x-axis labels on the top
ax.xaxis.tick_top()
# rotate the x-axis labels
plt.xticks(rotation=90)
# get figure (usually obtained via "fig,ax=plt.subplots()" with matplotlib)
fig = ax.get_figure()
# specify dimensions and save
fig.set_size_inches(15, 20)
fig.savefig("nba.png")

The output looks like this: I used the matplotlib Blues color map, but personally find the default colors quite beautiful. I used matplotlib to rotate the x-axis labels, as I couldn't find the seaborn syntax. As noted by grexor, it was necessary to specify the dimensions (fig.set_size_inches) by trial and error, which I found a bit frustrating.

As noted by Paul H, you can easily add the values to heat maps (annot=True), but in this case I didn't think it improved the figure. Several code snippets were taken from the excellent answer by joelotz.

I had a similar problem, which turned out to be caused by missing double quotes off the table and schema name.

I had luck with this:

  <Route
    path="/example"
    component={() => {
    global.window && (global.window.location.href = 'https://example.com');
    return null;
    }}
/>

Using Excel 2010 ? Try

Selection.PasteSpecial Paste:=xlPasteAllUsingSourceTheme, Operation:=xlNone, SkipBlanks:=False, Transpose:=False

I'm using

$this->db->query("SELECT * FROM film WHERE film.title LIKE '%$query%'"); for such purposes

Don't include header.php. You should not output HTML when you are going to redirect.

Make a new file, eg. "pre.php". Put this in it:

<?php
include('class.user.php');
include('class.Connection.php');
?>

Then in header.php, include that, in stead of including the two other files. In form.php, include pre.php in stead of header.php.

Just use TOP 100 Percent in the Select:

     CREATE VIEW [schema].[VIEWNAME] (
         [COLUMN1],
         [COLUMN2],
         [COLUMN3],
         [COLUMN4])
     AS 
        SELECT TOP 100 PERCENT 
         alias.[COLUMN1],
         alias.[COLUMN2],
         alias.[COLUMN3],
         alias.[COLUMN4]
        FROM 
           [schema].[TABLENAME] AS alias
          ORDER BY alias.COLUMN1
     GO

Here's some tested code using Java's URL class. I'd recommend do a better job than I do here of handling the exceptions or passing them up the call stack, though.

public static void main(String[] args) {
    URL url;
    InputStream is = null;
    BufferedReader br;
    String line;

    try {
        url = new URL("http://stackoverflow.com/");
        is = url.openStream();  // throws an IOException
        br = new BufferedReader(new InputStreamReader(is));

        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    } catch (MalformedURLException mue) {
         mue.printStackTrace();
    } catch (IOException ioe) {
         ioe.printStackTrace();
    } finally {
        try {
            if (is != null) is.close();
        } catch (IOException ioe) {
            // nothing to see here
        }
    }
}

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

If yout download a customized bootstrap 3 distro you must:

1. Download the full distro from https://github.com/twbs/bootstrap/archive/v3.0.0.zip
2. Uncompress and upload the entire folder called fonts to your bootstrap directory. Put together with the other folders "css, js".

Example Before:

\css
\js
index.html

Example After Upload:

\css
\fonts
\js
index.html

In your server.js :

var express   =     require("express");
var app       =     express();
app.use(express.static(__dirname + '/public'));

You have declared express and app separately, create a folder named 'public' or as you like, and yet you can access to these folder. In your template src, you have added the relative path from /public (or the name of your folder destiny to static files). Beware of the bars on the routes.

Do you mean that for a select element with an id of "next" you need to perform some specific script?

$("#next").change(function(){
    //enter code here
});

Seems simple enough, but gave me fits. I kept getting "icmp open socket operation not permitted" or else the solutions would hang up if the server was off line. If, however, what you want to know is that the server is alive and you are running a web server on that server, then curl will do the job. If you have ssh and certificates, then ssh and a simple command will suffice. Here is the code:

from easyprocess import EasyProcess # as root: pip install EasyProcess
def ping(ip):
    ping="ssh %s date;exit"%(ip) # test ssh alive or
    ping="curl -IL %s"%(ip)      # test if http alive
    response=len(EasyProcess(ping).call(timeout=2).stdout)
    return response #integer 0 if no response in 2 seconds

I had to do this in that order:

Install-Module MSOnline
Install-Module AzureAD
Import-Module AzureAD

I tried to start my binary, compiled with Qt 5.7, on Ubuntu 16.04 LTS where Qt 5.5 is preinstalled. It didn't work.

At first, I inspected the binary itself with ldd as was suggested here, and "satisfied" all "not found" dependencies. Then this notorious This application failed to start because it could not find or load the Qt platform plugin "xcb" error was thrown.

How to resolve this in Linux

Firstly you should create platforms directory where your binary is, because it is the place where Qt looks for XCB library. Copy libqxcb.so there. I wonder why authors of other answers didn't mention this.

Then you may want to run your binary with QT_DEBUG_PLUGINS=1 environment variable set to check which dependencies of libqxcb.so are not "satisfied". (You may also use ldd for this as suggested in the accepted answer).

The command output may look like this:

me@xerus:/media/sf_Qt/Package$ LD_LIBRARY_PATH=. QT_DEBUG_PLUGINS=1 ./Binary
QFactoryLoader::QFactoryLoader() checking directory path "/media/sf_Qt/Package/platforms" ...
QFactoryLoader::QFactoryLoader() looking at "/media/sf_Qt/Package/platforms/libqxcb.so"

    "MetaData": {
        "Keys": [
            "xcb"
        ]
    },
    "className": "QXcbIntegrationPlugin",
    "debug": false,
    "version": 329472
}


Got keys from plugin meta data ("xcb")
loaded library "/media/sf_Qt/Package/platforms/libqxcb.so"
QLibraryPrivate::loadPlugin failed on "/media/sf_Qt/Package/platforms/libqxcb.so" : "Cannot load library /media/sf_Qt/Package/platforms/libqxcb.so: (/usr/lib/x86_64-linux-gnu/libQt5DBus.so.5: version `Qt_5' not found (required by ./libQt5XcbQpa.so.5))"
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

Note the failing libQt5DBus.so.5 library. Copy it to your libraries path, in my case it was the same directory where my binary is (hence LD_LIBRARY_PATH=.). Repeat this process until all dependencies are satisfied.

P.S. thanks to the author of this answer for QT_DEBUG_PLUGINS=1.

Have you tried using the JQuery change event?

$("#g01-01").change(function() {
    if(this.checked) {
        //Do stuff
    }
});

Then you can also remove onchange="doalert(this.id)" from your checkbox :)

Edit:

I don't know if you are using JQuery, but if you're not yet using it, you will need to put the following script in your page so you can use it:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

If you only need to remove duplicates then use DISTINCT. GROUP BY should be used to apply aggregate operators to each group

GROUP BY v DISTINCT

The attribute selector syntax is [name=value] where name is the attribute name and value is the attribute value.

So if you want to select all input elements with the attribute name having the value inputName[]:

$('input[name="inputName[]"]')

And if you want to check for two attributes (here: name and value):

$('input[name="inputName[]"][value=someValue]')

I frequently do something like this when I need to get a few lines surrounding something I've grepped in a log file:

$ grep -n "xlrd" requirements.txt | awk -F ":" '{print $1}'
54

$ python -c "with open('requirements.txt') as file: print ''.join(file.readlines()[52:55])"
wsgiref==0.1.2
xlrd==0.9.2
xlwt==0.7.5

string.find("substring") will help you. This function returns -1 when there is no substring.

Not authoritative, but interesting: 21 is FTP, 23 is telnet. 22 is SSH...something in between (that can take the place of both).

For complete M B answer, if you want to access to an specific attribute of this object already filtered from the array in your HTML, you will have to do it in this way:

{{ (myArray | filter : {'id':73})[0].name }}

So, in this case, it will print john in the HTML.

Regards!

Based on the previous answers and personnal experience, here is the code I use to monitor CPU use. The code of this class is written in pure Java.

There are several ways of exploiting this class. You can call either syncGetSystemCpuUsage or syncGetProcessCpuUsage but each is blocking the calling thread. Since a common issue is to monitor the total CPU usage and the CPU use of the current process at the same time, I have designed a class computing both of them. That class contains a dedicated thread. The output management is implementation specific and you need to code your own.

The class can be customized by a few means. The constant CPU_WINDOW defines the depth of a read, i.e. the number of milliseconds between readings and computing of the corresponding CPU load. CPU_REFRESH_RATE is the time between each CPU load measurement. Do not set CPU_REFRESH_RATE to 0 because it will suspend the thread after the first read.

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

In case if you hate Inner classes, by taking the advantage of functional interface you can write less code in Java 8 with a lambda expression.

JsonDeserializer<Date> dateJsonDeserializer = 
     (json, typeOfT, context) -> json == null ? null : new Date(json.getAsLong());
Gson gson = new GsonBuilder().registerTypeAdapter(Date.class,dateJsonDeserializer).create();

One way would be to use a nested query:

SELECT count(*)
FROM (
   SELECT COUNT(Genre) AS count
   FROM movies
   GROUP BY ID
   HAVING (count = 4)
) AS x

The inner query gets all the movies that have exactly 4 genres, then outer query counts how many rows the inner query returned.

If you use Python3x then string is not the same type as for Python 2.x, you must cast it to bytes (encode it).

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))

Also do not use variable names like string or file while those are names of module or function.

EDIT @Tom

Yes, non-ASCII text is also compressed/decompressed. I use Polish letters with UTF-8 encoding:

plaintext = 'Polish text: acelnószzACELNÓSZZ'
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
    outfile_content = infile.read().decode('UTF-8')
print(outfile_content)

You could designate a class for each cell in the second column.

<table>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
</table>

This is my method if i got your point

HTML

<label for="FileInput">
    <img src="tools/img/upload2.png" style="cursor:pointer" onmouseover="this.src='tools/img/upload.png'" onmouseout="this.src='tools/img/upload2.png'" alt="Injaz Msila" style="float:right;margin:7px" />

<form action="upload.php">
    <input type="file" id="FileInput" style="cursor: pointer;  display: none"/>
    <input type="submit" id="Up" style="display: none;" />
</form>

jQuery

<script type="text/javascript">
    $( "#FileInput" ).change(function() {
      $( "#Up" ).click();
    });
</script>

Change

JSONObject objects = getArray.getJSONArray(i);

to

JSONObject objects = getArray.getJSONObject(i);

or to

JSONObject objects = getArray.optJSONObject(i);

depending on which JSON-to/from-Java library you're using. (It looks like getJSONObject will work for you.)

Then, to access the string elements in the "objects" JSONObject, get them out by element name.

String a = objects.get("A");

If you need the names of the elements in the JSONObject, you can use the static utility method JSONObject.getNames(JSONObject) to do so.

String[] elementNames = JSONObject.getNames(objects);

"Get the value for the first element and the value for the last element."

If "element" is referring to the component in the array, note that the first component is at index 0, and the last component is at index getArray.length() - 1.

I want to iterate though the objects in the array and get thier component and thier value. In my example the first object has 3 components, the scond has 5 and the third has 4 components. I want iterate though each of them and get thier component name and value.

The following code does exactly that.

import org.json.JSONArray;
import org.json.JSONObject;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    String jsonInput = "{\"JObjects\":{\"JArray1\":[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\"},{\"A\":\"a1\",\"B\":\"b2\",\"C\":\"c3\",\"D\":\"d4\",\"E\":\"e5\"},{\"A\":\"aa\",\"B\":\"bb\",\"C\":\"cc\",\"D\":\"dd\"}]}}";

    // "I want to iterate though the objects in the array..."
    JSONObject outerObject = new JSONObject(jsonInput);
    JSONObject innerObject = outerObject.getJSONObject("JObjects");
    JSONArray jsonArray = innerObject.getJSONArray("JArray1");
    for (int i = 0, size = jsonArray.length(); i < size; i++)
    {
      JSONObject objectInArray = jsonArray.getJSONObject(i);

      // "...and get thier component and thier value."
      String[] elementNames = JSONObject.getNames(objectInArray);
      System.out.printf("%d ELEMENTS IN CURRENT OBJECT:\n", elementNames.length);
      for (String elementName : elementNames)
      {
        String value = objectInArray.getString(elementName);
        System.out.printf("name=%s, value=%s\n", elementName, value);
      }
      System.out.println();
    }
  }
}
/*
OUTPUT:
3 ELEMENTS IN CURRENT OBJECT:
name=A, value=a
name=B, value=b
name=C, value=c

5 ELEMENTS IN CURRENT OBJECT:
name=D, value=d4

You may use a delegate to solve this issue. Here is an example that is showing how to update a textBox using diffrent thread

public delegate void UpdateTextCallback(string message);

private void TestThread()
{
    for (int i = 0; i <= 1000000000; i++)
    {
        Thread.Sleep(1000);                
        richTextBox1.Dispatcher.Invoke(
            new UpdateTextCallback(this.UpdateText),
            new object[] { i.ToString() }
        );
    }
}
private void UpdateText(string message)
{
    richTextBox1.AppendText(message + "\n");
}

private void button1_Click(object sender, RoutedEventArgs e)
{
   Thread test = new Thread(new ThreadStart(TestThread));
   test.Start();
}

TestThread method is used by thread named test to update textBox

$(document).mousedown(function(e) {
    if( e.button == 2 ) {
         e.preventDefault();
        return false;
    } 
});

I used the solution I found here : http://efavdb.com/mean-shift/ and it worked very well for me :

import numpy as np
from sklearn.cluster import MeanShift, estimate_bandwidth
from sklearn.datasets.samples_generator import make_blobs
import matplotlib.pyplot as plt
from itertools import cycle
from PIL import Image

#%% Generate sample data
centers = [[1, 1], [-.75, -1], [1, -1], [-3, 2]]
X, _ = make_blobs(n_samples=10000, centers=centers, cluster_std=0.6)

#%% Compute clustering with MeanShift

# The bandwidth can be automatically estimated
bandwidth = estimate_bandwidth(X, quantile=.1,
                               n_samples=500)
ms = MeanShift(bandwidth=bandwidth, bin_seeding=True)
ms.fit(X)
labels = ms.labels_
cluster_centers = ms.cluster_centers_

n_clusters_ = labels.max()+1

#%% Plot result
plt.figure(1)
plt.clf()

colors = cycle('bgrcmykbgrcmykbgrcmykbgrcmyk')
for k, col in zip(range(n_clusters_), colors):
    my_members = labels == k
    cluster_center = cluster_centers[k]
    plt.plot(X[my_members, 0], X[my_members, 1], col + '.')
    plt.plot(cluster_center[0], cluster_center[1],
             'o', markerfacecolor=col,
             markeredgecolor='k', markersize=14)
plt.title('Estimated number of clusters: %d' % n_clusters_)
plt.show()

You can use the PHP function apc_clear_cache.

Calling apc_clear_cache() will clear the system cache and calling apc_clear_cache('user') will clear the user cache.

$(".field-group_name").each(function() {
        console.log($(this).text());
    });

Use bootstrap .collapse instead of .hidden

Later in JQuery you can use .show() or .hide() to manipulate it

DateTime Picker can be used to pick both date and time that is why it is called 'Date and Time Picker'. You can set the "Format" property to "Custom" and set combination of different format specifiers to represent/pick date/time in different formats in the "Custom Format" property. However if you want to change Date, then the pop-up calendar can be used whereas in case of Time selection (in the same control you are bound to use up/down keys to change values.

For example a custom format " ddddd, MMMM dd, yyyy hh:mm:ss tt " will give you a result like this : "Thursday, August 20, 2009 02:55:23 PM".

You can play around with different combinations for format specifiers to suit your need e.g MMMM will give "August" whereas MM will give "Aug"

The problem with all these answers is that they do not take virtual directories into account.

Consider:

Site named "tempuri.com/" rooted at c:\domains\site
virtual directory "~/files" at c:\data\files
virtual directory "~/files/vip" at c:\data\VIPcust\files

So:

Server.MapPath("~/files/vip/readme.txt") 
  = "c:\data\VIPcust\files\readme.txt"

But there is no way to do this:

MagicResolve("c:\data\VIPcust\files\readme.txt") 
   = "http://tempuri.com/files/vip/readme.txt"

because there is no way to get a complete list of virtual directories.

Assuming you only want to disallow strings that match the regex completely (i.e., mmbla is okay, but mm isn't), this is what you want:

^(?!(?:m{2}|t)$).*$

(?!(?:m{2}|t)$) is a negative lookahead; it says "starting from the current position, the next few characters are not mm or t, followed by the end of the string." The start anchor (^) at the beginning ensures that the lookahead is applied at the beginning of the string. If that succeeds, the .* goes ahead and consumes the string.

FYI, if you're using Java's matches() method, you don't really need the the ^ and the final $, but they don't do any harm. The $ inside the lookahead is required, though.

You're doing nothing wrong! You've changed the directory, but only within the subshell that runs the script.

You can run the script in your current process with the "dot" command:

. proj

But I'd prefer Greg's suggestion to use an alias in this simple case.

Solution for Android Studio 3.6:

yourSwitch.setTextColor(getResources().getColor(R.color.yourColor));

Changes the text color of a in the color XML file defined value (yourColor).

When we define shrink resources true that time we can also define which resources we wanna keep and which don't I have added xml file in res/raw folder named keep.xml

before going further generate a single signed build and check in apk analyser tool which will show drawable-xhdpi-v4 has messenger_button_send_round_shadow.png which i want to remove for this test

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools"

       @drawable/com_facebook_button_like_icon_selected.png,
       @drawable/messenger_button_send_round_shadow.png,
