Update: A proposal with nicer syntax is on its way. Contributions are welcome.
Yes, there is - for scoped access in objects - ES6 introduces Symbol
s.
Symbols are unique, you can't gain access to one from the outside except with reflection (like privates in Java/C#) but anyone who has access to a symbol on the inside can use it for key access:
var property = Symbol();
class Something {
constructor(){
this[property] = "test";
}
}
var instance = new Something();
console.log(instance.property); //=> undefined, can only access with access to the Symbol
In current JavaScript, I'm fairly certain that there is one and only one way to have private state, accessible from prototype functions, without adding anything public to this
. The answer is to use the "weak map" pattern.
To sum it up: The Person
class has a single weak map, where the keys are the instances of Person, and the values are plain objects that are used for private storage.
Here is a fully functional example: (play at http://jsfiddle.net/ScottRippey/BLNVr/)
var Person = (function() {
var _ = weakMap();
// Now, _(this) returns an object, used for private storage.
var Person = function(first, last) {
// Assign private storage:
_(this).firstName = first;
_(this).lastName = last;
}
Person.prototype = {
fullName: function() {
// Retrieve private storage:
return _(this).firstName + _(this).lastName;
},
firstName: function() {
return _(this).firstName;
},
destroy: function() {
// Free up the private storage:
_(this, true);
}
};
return Person;
})();
function weakMap() {
var instances=[], values=[];
return function(instance, destroy) {
var index = instances.indexOf(instance);
if (destroy) {
// Delete the private state:
instances.splice(index, 1);
return values.splice(index, 1)[0];
} else if (index === -1) {
// Create the private state:
instances.push(instance);
values.push({});
return values[values.length - 1];
} else {
// Return the private state:
return values[index];
}
};
}
Like I said, this is really the only way to achieve all 3 parts.
There are two caveats, however. First, this costs performance -- every time you access the private data, it's an O(n)
operation, where n
is the number of instances. So you won't want to do this if you have a large number of instances.
Second, when you're done with an instance, you must call destroy
; otherwise, the instance and the data will not be garbage collected, and you'll end up with a memory leak.
And that's why my original answer, "You shouldn't", is something I'd like to stick to.
The double underscore. It mangles the name in such a way that it can't be accessed simply through __fieldName
from outside the class, which is what you want to begin with if they're to be private. (Though it's still not very hard to access the field.)
class Foo:
def __init__(self):
self.__privateField = 4;
print self.__privateField # yields 4 no problem
foo = Foo()
foo.__privateField
# AttributeError: Foo instance has no attribute '__privateField'
It will be accessible through _Foo__privateField
instead. But it screams "I'M PRIVATE DON'T TOUCH ME", which is better than nothing.
If you have a big list, It's better to use itertools and write a function to yield each part as needed:
from itertools import islice
def make_chunks(data, SIZE):
it = iter(data)
# use `xragne` if you are in python 2.7:
for i in range(0, len(data), SIZE):
yield [k for k in islice(it, SIZE)]
You can use this like:
A = [0, 1, 2, 3, 4, 5, 6]
size = len(A) // 2
for sample in make_chunks(A, size):
print(sample)
The output is:
[0, 1, 2]
[3, 4, 5]
[6]

Please try this query:
Combine two tables that have no common columns:

You need to set Opacity first for standards-compliant browsers, then the various versions of IE. See Example:
but this opacity code not work in ie8
.slidedownTrigger
{
cursor: pointer;
opacity: .75; /* Standards Compliant Browsers */
filter: alpha(opacity=75); /* IE 7 and Earlier */
/* Next 2 lines IE8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=75)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=75);
}
Note that I eliminated -moz as Firefox is a Standards Compliant browser and that line is no longer necessary. Also, -khtml is depreciated, so I eliminated that style as well.
Furthermore, IE's filters will not validate to w3c standards, so if you want your page to validate, separate your standards stylesheet from your IE stylesheet by using an if IE statement like below:
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="http://www.mysite.com/css/ie.css" />
<![endif]-->
If you separate the ie quirks, your site will validate just fine.
Try this:
Dim strFile As String = "yourfile.txt"
Dim fileExists As Boolean = File.Exists(strFile)
Using sw As New StreamWriter(File.Open(strFile, FileMode.OpenOrCreate))
sw.WriteLine( _
IIf(fileExists, _
"Error Message in Occured at-- " & DateTime.Now, _
"Start Error Log for today"))

If you found “HAX is not working and emulator runs in emulation mode” problem while running android SDK.

If you read this, it's probably because all the previous answers didn't work for your Holo Dark based theme.
Holo Dark uses an additional wrapper for the PopupMenus, so after doing what Jonik suggested you have to add the following style to your 'xml' file:
<style name="PopupWrapper" parent="@android:style/Theme.Holo">
<item name="android:popupMenuStyle">@style/YourPopupMenu</item>
</style>
Then reference it in your theme block:
<style name="Your.cool.Theme" parent="@android:style/Theme.Holo">
.
.
.
<item name="android:actionBarWidgetTheme">@style/PopupWrapper</item>
</style>
That's it!
The error is here:
hasLetter("a",words[]);
You are passing the first item of words
, instead of the array.
Instead, pass the array to the function:
hasLetter("a",words);
Problem solved!
Here's a breakdown of what the problem was:
I'm guessing in your browser (chrome throws a different error), words[] == words[0]
, so when you call hasLetter("a",words[]);
, you are actually calling hasLetter("a",words[0]);
. So, in essence, you are passing the first item of words to your function, not the array as a whole.
Of course, because words
is just an empty array, words[0]
is undefined
. Therefore, your function call is actually:
hasLetter("a", undefined);
which means that, when you try to access d[ascii]
, you are actually trying to access undefined[0]
, hence the error.
You definitely can return array of configurations from your webpack.config file. But it's not an optimal solution if you just want a copy of artifacts to be in the folder of your project's documentation, since it makes webpack build your code twice doubling the overall time to build.
In this case I'd recommend to use the FileManagerWebpackPlugin plugin instead:
const FileManagerPlugin = require('filemanager-webpack-plugin');
// ...
plugins: [
// ...
new FileManagerPlugin({
onEnd: {
copy: [{
source: './dist/*.*',
destination: './public/',
}],
},
}),
],
This code works for me:
<?php
$date = "21.12.2015";
$newDate = date("d.m.Y",strtotime($date."+2 day"));
echo $newDate; // print 23.12.2015
?>
my 2 cents:
$('#theDiv').prepend($('<img>',{id:'theImg',src:'theImg.png'}))
Try document.getElementById("FileUpload1").value
this value should have a path for a file to be uploaded, just strip all dirs from that value and you will have file name.
The problem could be that the file is still seen as opened and locked by a program; or maybe it is a component from your program that it had been opened in, so you have to ensure you use the dispose()
method to solve that problem.
i.e. JFrame frame;
....
frame.dispose();

I know this is old, but I'm still getting the problem and this is the first link on Google for it. OP said his issue was that the .db was sitting on a SMB share, which was exactly my situation. My ten minutes' research indicates that this is a known conflict between sqlite3 and smb; I've found bug reports going back to 2007.
I resolved it by adding the "nobrl" option to my smb mount line in /etc/fstab, so that line now looks like this:
//SERVER/share /mnt/point cifs credentials=/path/to/.creds,sec=ntlm,nobrl 0 0
This option prevents your SMB client from sending byte range locks to the server. I'm not too up on my SMB protocol details, but I best I can tell this setting would mostly be of concern in a multi-user environment, where somebody else might be trying to write to the same db as you. For a home setup, at least, I think it's safe enough.
My relevant versions:
If you try to add a form warping a tr element like this
<table>
<form>
<tr>
<td><input type="text"/></td>
<td><input type="submit"/></td>
</tr>
</form>
</table>
some browsers in the process of rendering will close form tag right after the declaration leaving inputs outside of the element
something like this
<table>
<form></form>
<tr>
<td><input type="text"/></td>
<td><input type="submit"/></td>
</tr>
</table>
This issue is still valid for warping multiple table cells
As stereoscott said above, nesting tables are a possible solution which is not recommended. Avoid using tables.
In my makefile I use this:
@sed -i '/.*Revision:.*/c\'"`svn info -R main.cpp | awk '/^Rev/'`"'' README.md
PS: DO NOT forget that the -i changes actually the text in the file... so if the pattern you defined as "Revision" will change, you will also change the pattern to replace.
Example output:
Abc-Project written by John Doe
Revision: 1190
So if you set the pattern "Revision: 1190" it's obviously not the same as you defined them as "Revision:" only...

Use following data types as per your need
TINYBLOB : maximum length of 255 bytes
BLOB : maximum length of 65,535 bytes
MEDIUMBLOB : maximum length of 16,777,215 bytes
LONGBLOB : maximum length of 4,294,967,295 bytes
Use LONGBLOB

Altering the class model-dialog
you can achieve expected result. These small tricks work for me. Hope it will help you to solve this issue.
.modal-dialog {
width: 70%;
}
this:
(<.+?> | )
will match any tag or
string regex = @"(<.+?>| )";
var x = Regex.Replace(originalString, regex, "").Trim();
then x = hello
Also, take a look at FrameLayout
, that's how the Camera's Gallery application implements the Zoom buttons overlay.
By default, a batch file will display its command as it runs. The purpose of this first command which @echo off is to turn off this display. The command "echo off" turns off the display for the whole script, except for the "echo off" command itself. The "at" sign "@" in front makes the command apply to itself as well.
The common approach would be to check it with a regular expression like it's also suggested inside the Double.valueOf(String)
documentation.
The regexp provided there (or included below) should cover all valid floating point cases, so you don't need to fiddle with it, since you will eventually miss out on some of the finer points.
If you don't want to do that, try catch
is still an option.
The regexp suggested by the JavaDoc is included below:
final String Digits = "(\\p{Digit}+)";
final String HexDigits = "(\\p{XDigit}+)";
// an exponent is 'e' or 'E' followed by an optionally
// signed decimal integer.
final String Exp = "[eE][+-]?"+Digits;
final String fpRegex =
("[\\x00-\\x20]*"+ // Optional leading "whitespace"
"[+-]?(" + // Optional sign character
"NaN|" + // "NaN" string
"Infinity|" + // "Infinity" string
// A decimal floating-point string representing a finite positive
// number without a leading sign has at most five basic pieces:
// Digits . Digits ExponentPart FloatTypeSuffix
//
// Since this method allows integer-only strings as input
// in addition to strings of floating-point literals, the
// two sub-patterns below are simplifications of the grammar
// productions from the Java Language Specification, 2nd
// edition, section 3.10.2.
// Digits ._opt Digits_opt ExponentPart_opt FloatTypeSuffix_opt
"((("+Digits+"(\\.)?("+Digits+"?)("+Exp+")?)|"+
// . Digits ExponentPart_opt FloatTypeSuffix_opt
"(\\.("+Digits+")("+Exp+")?)|"+
// Hexadecimal strings
"((" +
// 0[xX] HexDigits ._opt BinaryExponent FloatTypeSuffix_opt
"(0[xX]" + HexDigits + "(\\.)?)|" +
// 0[xX] HexDigits_opt . HexDigits BinaryExponent FloatTypeSuffix_opt
"(0[xX]" + HexDigits + "?(\\.)" + HexDigits + ")" +
")[pP][+-]?" + Digits + "))" +
"[fFdD]?))" +
"[\\x00-\\x20]*");// Optional trailing "whitespace"
if (Pattern.matches(fpRegex, myString)){
Double.valueOf(myString); // Will not throw NumberFormatException
} else {
// Perform suitable alternative action
}
here is my solution for slide & fade effect:
// Add slideup & fadein animation to dropdown
$('.dropdown').on('show.bs.dropdown', function(e){
var $dropdown = $(this).find('.dropdown-menu');
var orig_margin_top = parseInt($dropdown.css('margin-top'));
$dropdown.css({'margin-top': (orig_margin_top + 10) + 'px', opacity: 0}).animate({'margin-top': orig_margin_top + 'px', opacity: 1}, 300, function(){
$(this).css({'margin-top':''});
});
});
// Add slidedown & fadeout animation to dropdown
$('.dropdown').on('hide.bs.dropdown', function(e){
var $dropdown = $(this).find('.dropdown-menu');
var orig_margin_top = parseInt($dropdown.css('margin-top'));
$dropdown.css({'margin-top': orig_margin_top + 'px', opacity: 1, display: 'block'}).animate({'margin-top': (orig_margin_top + 10) + 'px', opacity: 0}, 300, function(){
$(this).css({'margin-top':'', display:''});
});
});
It's not too hard. Firstly, take a look at FileReader Interface.
So, when the form is submitted, catch the submission process and
var file = document.getElementById('fileBox').files[0]; //Files[0] = 1st file
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = shipOff;
//reader.onloadstart = ...
//reader.onprogress = ... <-- Allows you to update a progress bar.
//reader.onabort = ...
//reader.onerror = ...
//reader.onloadend = ...
function shipOff(event) {
var result = event.target.result;
var fileName = document.getElementById('fileBox').files[0].name; //Should be 'picture.jpg'
$.post('/myscript.php', { data: result, name: fileName }, continueSubmission);
}
Then, on the server side (i.e. myscript.php):
$data = $_POST['data'];
$fileName = $_POST['name'];
$serverFile = time().$fileName;
$fp = fopen('/uploads/'.$serverFile,'w'); //Prepends timestamp to prevent overwriting
fwrite($fp, $data);
fclose($fp);
$returnData = array( "serverFile" => $serverFile );
echo json_encode($returnData);
Or something like it. I may be mistaken (and if I am, please, correct me), but this should store the file as something like 1287916771myPicture.jpg
in /uploads/
on your server, and respond with a JSON variable (to a continueSubmission()
function) containing the fileName on the server.
Check out fwrite()
and jQuery.post()
.
On the above page it details how to use readAsBinaryString()
, readAsDataUrl()
, and readAsArrayBuffer()
for your other needs (e.g. images, videos, etc).
If you are using jQuery you can also do this:
$('#leaveCode').val('14');
This will select the <option>
with the value of 14.
With plain Javascript, this can also be achieved with two Document
methods:
With document.querySelector
, you can select an element based on a CSS selector:
document.querySelector('#leaveCode').value = '14'
Using the more established approach with document.getElementById()
, that will, as the name of the function implies, let you select an element based on its id
:
document.getElementById('leaveCode').value = '14'
You can run the below code snipped to see these methods and the jQuery function in action:
const jQueryFunction = () => {_x000D_
_x000D_
$('#leaveCode').val('14'); _x000D_
_x000D_
}_x000D_
_x000D_

_x000D_
document.querySelector('#leaveCode').value = '14' _x000D_
_x000D_
}_x000D_
_x000D_
const getElementByIdFunction = () => {_x000D_
_x000D_
document.getElementById('leaveCode').value='14' _x000D_
_x000D_
}
_x000D_
input {_x000D_
display:block;_x000D_
margin: 10px;_x000D_
padding: 10px_x000D_
}
_x000D_
<select id="leaveCode" name="leaveCode">_x000D_
<option value="10">Annual Leave</option>_x000D_
<option value="11">Medical Leave</option>_x000D_
<option value="14">Long Service</option>_x000D_
<option value="17">Leave Without Pay</option>_x000D_
</select>_x000D_
_x000D_
<input type="button" value="$('#leaveCode').val('14');" onclick="jQueryFunction()" />_x000D_
<input type="button" value="document.querySelector('#leaveCode').value = '14'" onclick="querySelectorFunction()" />_x000D_
<input type="button" value="document.getElementById('leaveCode').value = '14'" onclick="getElementByIdFunction()" />_x000D_
_x000D_

Better design would be
public static YourObject getMyObject(File configFile){
//process and create an object configure it and return it
}
Instead of getting IMEI from TelephonyManager use ANDROID_ID.
Settings.Secure.ANDROID_ID
This works for each android device irrespective of having telephony.
I suspect you're facing the issue where your package.json
file is not in the same directory as your Gruntfile.js
. When you run your grunt xxx
commands, you get error an message like:
Local Npm module "xxx" not found. Is it installed?
For now, the solution is:
npm install
to load them locallyIMHO, it is sad that we cannot have grunt resolve modules loaded from a parent npm module (i.e. package.json in a parent directory within the same project). The discussion here seems to indicate that it was done to avoid loading "global" modules but I think what we want is loading from "my project" modules instead.
I have put something like this in my Controller class and it worked:
IdentityUser user = await userManager.FindByNameAsync(HttpContext.User.Identity.Name);
where userManager is an instance of Microsoft.AspNetCore.Identity.UserManager class (with all weird setup that goes with it).

There are two ways to assign argument values to function parameters, both are used.
By Position. Positional arguments do not have keywords and are assigned first.
By Keyword. Keyword arguments have keywords and are assigned second, after positional arguments.
Note that you have the option to use positional arguments.
If you don't use positional arguments, then -- yes -- everything you wrote turns out to be a keyword argument.
When you call a function you make a decision to use position or keyword or a mixture. You can choose to do all keywords if you want. Some of us do not make this choice and use positional arguments.
DATE: It is used for values with a date part but no time part. MySQL retrieves and displays DATE values in YYYY-MM-DD format. The supported range is 1000-01-01
to 9999-12-31
.
DATETIME: It is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format. The supported range is 1000-01-01 00:00:00
to 9999-12-31 23:59:59
.
TIMESTAMP: It is also used for values that contain both date and time parts, and includes the time zone. TIMESTAMP has a range of 1970-01-01 00:00:01
UTC to 2038-01-19 03:14:07
UTC.
TIME: Its values are in HH:MM:SS format (or HHH:MM:SS format for large hours values). TIME values may range from -838:59:59
to 838:59:59
. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
I got the same error but from a backend job (SSIS job). Upon checking the database's Log file growth setting, the log file was limited growth of 1GB. So what happened is when the job ran and it asked SQL server to allocate more log space, but the growth limit of the log declined caused the job to failed. I modified the log growth and set it to grow by 50MB and Unlimited Growth and the error went away.

Absolutely, yes you can. This link contains details about how you can achieve that: https://api.jquery.com/jquery.noconflict/.
This seems to explain it.
The definition of
order
is thata[order(a)]
is in increasing order. This works with your example, where the correct order is the fourth, second, first, then third element.You may have been looking for
rank
, which returns the rank of the elements
R> a <- c(4.1, 3.2, 6.1, 3.1)
R> order(a)
[1] 4 2 1 3
R> rank(a)
[1] 3 2 4 1
sorank
tells you what order the numbers are in,order
tells you how to get them in ascending order.
plot(a, rank(a)/length(a))
will give a graph of the CDF. To see whyorder
is useful, though, tryplot(a, rank(a)/length(a),type="S")
which gives a mess, because the data are not in increasing orderIf you did
oo<-order(a)
plot(a[oo],rank(a[oo])/length(a),type="S")
or simply
oo<-order(a)
plot(a[oo],(1:length(a))/length(a)),type="S")
you get a line graph of the CDF.
I'll bet you're thinking of rank.

In my case because I assigned the post data to the header, this is how I get it:
protected void Page_Load(object sender, EventArgs e){
...
postValue = Request.Headers["Key"];
This is how I attached the value and key to the POST
:
var request = new NSMutableUrlRequest(url){
HttpMethod = "POST",
Headers = NSDictionary.FromObjectAndKey(FromObject(value), FromObject("key"))
};
webView.LoadRequest(request);
I've just come across this, and thought I'd add my thoughts. As others have suggested, I'd recommend manually adding IDs, but if you really want something close to what you've described, you could use this:
var objectId = (function () {
var allObjects = [];
var f = function(obj) {
if (allObjects.indexOf(obj) === -1) {
allObjects.push(obj);
}
return allObjects.indexOf(obj);
}
f.clear = function() {
allObjects = [];
};
return f;
})();
You can get any object's ID by calling objectId(obj)
. Then if you want the id to be a property of the object, you can either extend the prototype:
Object.prototype.id = function () {
return objectId(this);
}
or you can manually add an ID to each object by adding a similar function as a method.
The major caveat is that this will prevent the garbage collector from destroying objects when they drop out of scope... they will never drop out of the scope of the allObjects
array, so you might find memory leaks are an issue. If your set on using this method, you should do so for debugging purpose only. When needed, you can do objectId.clear()
to clear the allObjects
and let the GC do its job (but from that point the object ids will all be reset).
Above answers are great, but as jquery evolves.. so you can also do:
var myId = $("#test").prop("id");
You can use MATCH
for instance.
Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.
In the entry box, put:
=MATCH(A2, 'Sheet2'!A:A, 0)
Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.
MATCH
takes the value A2
from your data table, looks into 'Sheet2'!A:A
and if there's an exact match (that's why there's a 0
at the end), then it'll return the row number.
Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.
EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:
=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))
There are commercial products such as ionCube (which I use), source guardian, and Zen Guard.
There are also postings on the net which claim they can reverse engineer the encoded programs. How reliable they are is questionable, since I have never used them.
Note that most of these solutions require an encoder to be installed on their servers. So you may want to make sure your client is comfortable with that.
This is to keep requesting inputs while this input is integer and find whether it is odd or even else it will end.
int counter = 1;
System.out.println("Enter a number:");
Scanner OddInput = new Scanner(System.in);
while(OddInput.hasNextInt()){
int Num = OddInput.nextInt();
if (Num %2==0){
System.out.println("Number " + Num + " is Even");
System.out.println("Enter a number:");
}
else {
System.out.println("Number " + Num + " is Odd");
System.out.println("Enter a number:");
}
}
System.out.println("Program Ended");
}

You could use numpy.arange
.
EDIT: The docs prefer numpy.linspace
. Thanks @Droogans for noticing =)
If you want to run a cron every n
minutes, there are a few possible options depending on the value of n
.
n
divides 60 (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30)
Here, the solution is straightforward by making use of the /
notation:
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7)
# | | | | |
# * * * * * command to be executed
m-59/n * * * * command
In the above, n
represents the value n
and m
represents a value smaller than n
or *
. This will execute the command at the minutes m,m+n,m+2n,...
n
does NOT divide 60
If n
does not divide 60, you cannot do this cleanly with cron but it is possible. To do this you need to put a test in the cron where the test checks the time. This is best done when looking at the UNIX timestamp, the total seconds since 1970-01-01 00:00:00 UTC
. Let's say we want to start to run the command the first time when Marty McFly arrived in Riverdale and then repeat it every n
minutes later.
% date -d '2015-10-21 07:28:00' +%s
1445412480
For a cronjob to run every 42
nd minute after `2015-10-21 07:28:00', the crontab would look like this:
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7)
# | | | | |
# * * * * * command to be executed
* * * * * minutetestcmd "2015-10-21 07:28:00" 42 && command
with minutetestcmd
defined as
#!/usr/bin/env bash
starttime=$(date -d "$1" "+%s")
# return UTC time
now=$(date "+%s")
# get the amount of minutes (using integer division to avoid lag)
minutes=$(( (now - starttime) / 60 ))
# set the modulo
modulo=$2
# do the test
(( now >= starttime )) && (( minutes % modulo == 0 ))
Remark: UNIX time is not influenced by leap seconds
Remark: cron
has no sub-second accuracy
The answers above are already quite great, but I really want to share the following summary article: "6 Ways to Run Shell Commands in Ruby"
Basically, it tells us:
Kernel#exec
:
exec 'echo "hello $HOSTNAME"'
system
and $?
:
system 'false'
puts $?
Backticks (`):
today = `date`
IO#popen
:
IO.popen("date") { |f| puts f.gets }
Open3#popen3
-- stdlib:
require "open3"
stdin, stdout, stderr = Open3.popen3('dc')
Open4#popen4
-- a gem:
require "open4"
pid, stdin, stdout, stderr = Open4::popen4 "false" # => [26327, #<IO:0x6dff24>, #<IO:0x6dfee8>, #<IO:0x6dfe84>]
Below a fully functional method to get hard disk serial number:

{
ManagementClass mangnmt = new ManagementClass("Win32_LogicalDisk");

foreach (ManagementObject strt in mcol)
{
result += Convert.ToString(strt["VolumeSerialNumber"]);
}
return result;
}
The best way is to use menu mnemonics, i.e. to have menu entries in your main form that get assigned the keyboard shortcut you want. Then everything else is handled internally and all you have to do is to implement the appropriate action that gets executed in the Click
event handler of that menu entry.
i'll make an example,
first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit)
, and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),
setting up the netcat server to listen on port 9999: nc -l 9999
now hitting http://127.0.0.1:9999 in firefox, i get:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1
now let us compare that with this simple script:
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);
i get:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*
there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent
specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding
header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
CURLOPT_ENCODING=>'gzip, deflate',
CURLOPT_HTTPHEADER=>array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: en-US,en;q=0.5',
'Connection: keep-alive',
'Upgrade-Insecure-Requests: 1',
),
));
curl_exec($ch);
now running that code, our netcat server gets:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1
and voila! our php-emulated browser
GET request should now be indistinguishable from the real firefox GET request :)
this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding
header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
CURLOPT_ENCODING=>'gzip, deflate',
CURLOPT_HTTPHEADER=>array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: en-US,en;q=0.5',
'Accept-Encoding: gzip, deflate',
'Connection: keep-alive',
'Upgrade-Insecure-Requests: 1',
),
));
curl_exec($ch);
running that, our netcat server gets:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1
problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)
Consider using Regular Expressions or FTP Globbing. By that you could start wget multiple times with different groups of filename starting characters depending on their frequency of occurrence.
This is for example how I sync a folder between two NAS:
wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.10 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[0-9a-hA-H]*" --directory-prefix=/volume1/foo &
wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.11 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[!0-9a-hA-H]*" --directory-prefix=/volume1/foo &
The first wget syncs all files/folders starting with 0, 1, 2... F, G, H
and the second thread syncs everything else.
This was the easiest way to sync between a NAS with one 10G ethernet port (10.0.0.100) and a NAS with two 1G ethernet ports (10.0.0.10 and 10.0.0.11). I bound the two wget threads through --bind-address
to the different ethernet ports and called them parallel by putting &
at the end of each line. By that I was able to copy huge files with 2x 100 MB/s = 200 MB/s in total.
Concerning semantics, I do not like any solution given so far. Therefore, I personally use the following solution:
.img-wrapper {_x000D_
display: inline-block;_x000D_
background-image: url(https://www.w3schools.com/w3images/fjords.jpg);_x000D_
}_x000D_
_x000D_
.img-wrapper > img {_x000D_
vertical-align: top;_x000D_
}_x000D_
_x000D_
.img-wrapper > img:hover {_x000D_
opacity: 0;_x000D_
}
_x000D_
<div class="img-wrapper">_x000D_
<img src="https://www.w3schools.com/w3css/img_lights.jpg" alt="image" />_x000D_
</div>
_x000D_
This is a CSS only solution with good browser compatibility. It makes use of an image wrapper that has a background which is initially hidden by the image itself. On hover, the image is hidden through the opacity, hence the background image becomes visible. This way, one does not have an empty wrapper but a real image in the markup code.
Thanks to @pgregory, I could resolve my problem using this directive for inline editing
.directive("superEdit", function($compile){
return{
link: function(scope, element, attrs){
var colName = attrs["superEdit"];
alert(colName);
scope.getContentUrl = function() {
if (colName == 'Something') {
return 'app/correction/templates/lov-edit.html';
}else {
return 'app/correction/templates/simple-edit.html';
}
}
var template = '<div ng-include="getContentUrl()"></div>';
var linkFn = $compile(template);
var content = linkFn(scope);
element.append(content);
}
}
})
As an alternative to the other (very good) answers, you could cast to uintptr_t
or intptr_t
(from stdint.h
/inttypes.h
) and use the corresponding integer conversion specifiers. This would allow more flexibility in how the pointer is formatted, but strictly speaking an implementation is not required to provide these typedefs.
You can use the "User-Defined Language" option available at the notepad++. You do not need to do the xml-based hacks, where the formatting would be available only in the searched window, with the formatting rules.
Sample for your reference here.
Try to never use relative paths. Use a generic include where you assign the DocumentRoot server variable to a global variable, and construct absolute paths from there. Alternatively, for larger projects, consider implementing a PSR-0 SPL autoloader.
Tried this on firefox, works http://jsfiddle.net/Tm26Q/1/
$(function(){
/** Just to mimic a blinking box on the page**/
setInterval(function(){$("div#box").hide();},2001);
setInterval(function(){$("div#box").show();},1000);
/**/
});
$("div#box").on("DOMAttrModified",
function(){if($(this).is(":visible"))console.log("visible");});
UPDATE
Currently the Mutation Events (like
DOMAttrModified
used in the solution) are replaced by MutationObserver, You can use that to detect DOM node changes like in the above case.
Download desired version of hadoop folder (Say if you are installing spark on Windows then hadoop version for which your spark is built for) from this link as zip.
Extract the zip to desired directory.
You need to have directory of the form hadoop\bin
(explicitly create such hadoop\bin
directory structure if you want) with bin
containing all the files contained in bin
folder of the downloaded hadoop. This will contain many files such as hdfs.dll, hadoop.dll etc. in addition to winutil.exe.
Now create environment variable HADOOP_HOME
and set it to <path-to-hadoop-folder>\hadoop
. Then add ;%HADOOP_HOME%\bin;
to PATH
environment variable.
Open a "new command prompt" and try rerunning your command.

You can verify the number of visible cells using this function:
- (NSArray *)visibleCells
This method will return an array with the cells that are visible, so you can count the number of objects in this array and compare with the number of objects in your table.. if it's equal.. you can disable the scrolling using:
tableView.scrollEnabled = NO;
As @Ginny mentioned.. we would can have problems with partially visible cells, so this solution works better in this case:
tableView.scrollEnabled = (tableView.contentSize.height <= CGRectGetHeight(tableView.frame));
In case you are using autoLayout this solution do the job:
tableView.alwaysBounceVertical = NO.
Make sure you are starting Eclipse with Administrator rights.
The short answer is: don't. If you want code that reads linearly, use a library like seq. But just don't expect synchronous. You really can't. And that's a good thing.
There's little or nothing that can't be put in a callback. If they depend on common variables, create a closure to contain them. What's the actual task at hand?
You'd want to have a counter, and only call the callback when the data is there:
var waiting = 2;
request( {url: base + u_ext}, function( err, res, body ) {
var split1 = body.split("\n");
var split2 = split1[1].split(", ");
ucomp = split2[1];
if(--waiting == 0) callback();
});
request( {url: base + v_ext}, function( err, res, body ) {
var split1 = body.split("\n");
var split2 = split1[1].split(", ");
vcomp = split2[1];
if(--waiting == 0) callback();
});
function callback() {
// do math here.
}
Update 2018: node.js supports async/await keywords in recent editions, and with libraries that represent asynchronous processes as promises, you can await them. You get linear, sequential flow through your program, and other work can progress while you await. It's pretty well built and worth a try.
Th easiest way to this is var id = $(this).val(); from inside an event like on change.
The main difference between localStorage
and sessionStorage
is that sessionStorage
is unique per tab. If you close the tab the sessionStorage
gets deleted, localStorage
does not. Also you cannot communicate between tabs :)
Another subtle difference is that for example on Safari (8.0.3) localStorage
has a limit of 2551 k characters but sessionStorage
has unlimited storage
On Chrome (v43) both localStorage
and sessionStorage
are limited to 5101 k characters (no difference between normal / incognito mode)
On Firefox both localStorage
and sessionStorage
are limited to 5120 k characters (no difference between normal / private mode )
No difference in speed whatsoever :)
There's also a problem with Mobile Safari and Mobile Chrome, Private Mode Safari & Chrome have a maximum space of 0KB
Try something like the following example, quoted from the output of IF /?
on Windows XP:
IF EXIST filename. ( del filename. ) ELSE ( echo filename. missing. )
You can also check for a missing file with IF NOT EXIST
.
The IF
command is quite powerful. The output of IF /?
will reward careful reading. For that matter, try the /?
option on many of the other built-in commands for lots of hidden gems.

For my fellow zsh users, the way to accomplish the same thing as the accepted answer is to use:
${(P)a}
It is appropriately called Parameter name replacement
This forces the value of the parameter name to be interpreted as a further parameter name, whose value will be used where appropriate. Note that flags set with one of the typeset family of commands (in particular case transformations) are not applied to the value of name used in this fashion.
If used with a nested parameter or command substitution, the result of that will be taken as a parameter name in the same way. For example, if you have ‘foo=bar’ and ‘bar=baz’, the strings ${(P)foo}, ${(P)${foo}}, and ${(P)$(echo bar)} will be expanded to ‘baz’.
Likewise, if the reference is itself nested, the expression with the flag is treated as if it were directly replaced by the parameter name. It is an error if this nested substitution produces an array with more than one word. For example, if ‘name=assoc’ where the parameter assoc is an associative array, then ‘${${(P)name}[elt]}’ refers to the element of the associative subscripted ‘elt’.
StringUtils.abbreviate("abcdefg", 6);
This will give you the following result: abc...
Where 6 is the needed length, and "abcdefg" is the string that needs to be abbrevieted.
The &&
function is not vectorized. You need the &
function:

switch of PuTTY takes a path to a script file as an argument, not a command.
Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m
So you have to save your command (command_run
) to a plain text file (e.g. c:\path\command.txt
) and pass that to PuTTY:
putty.exe -ssh user@host -pw password -m c:\path\command.txt
Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).
A command-line syntax is identical, an output redirection added:
plink.exe -ssh user@host -pw password -m c:\path\command.txt > output.txt
See Using the command-line connection tool Plink.
And with Plink, you can actually provide the command directly on its command-line:
plink.exe -ssh user@host -pw password command > output.txt
Similar questions:

Executing command in Plink from a batch file
Make sure that you actually save the file as UTF-8, alternatively use HTML entities (&#nnn;
) for the special characters.
The Best way to Print particular Div or any Element
printDiv("myDiv");
function printDiv(id){
var printContents = document.getElementById(id).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
}
The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):
Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)
"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.
As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.
It should run properly at cron also. Please check below things.
1- You are editing proper file to set cron.
2- You have given proper permission(execute permission) to script mean your script is executable.
You can use shorthand syntax as of Twig 1.12.0
{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}
To make the images flexible, simply add
max-width:100%
andheight:auto
. Imagemax-width:100%
andheight:auto
works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to addwidth:auto\9
for IE8.source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries
for example :
img {
max-width: 100%;
height: auto;
width: auto\9; /* ie8 */
}
and then any images you add simply using the img tag will be flexible
JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).
data.reindex(index=data.index[::-1])
or simply:
data.iloc[::-1]
will reverse your data frame, if you want to have a for
loop which goes from down to up you may do:
for idx in reversed(data.index):
print(idx, data.loc[idx, 'Even'], data.loc[idx, 'Odd'])
or
for idx in reversed(data.index):
print(idx, data.Even[idx], data.Odd[idx])
You are getting an error because reversed
first calls data.__len__()
which returns 6. Then it tries to call data[j - 1]
for j
in range(6, 0, -1)
, and the first call would be data[5]
; but in pandas dataframe data[5]
means column 5, and there is no column 5 so it will throw an exception. ( see docs )
$today=date('d-m-Y');
$next_date= date('d-m-Y', strtotime($today. ' + 90 days'));
echo $next_date;
GROUP BY YEAR(record_date), MONTH(record_date)
Check out the date and time functions in MySQL.
To get the value of cell, use the following syntax,
datagridviewName(columnFirst, rowSecond).value
But the intellisense and MSDN documentation is wrongly saying rowFirst, colSecond

You need to instantiate the view controller from the storyboard and then show it:
ViewControllerInfo* infoController = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewControllerInfo"];
[self.navigationController pushViewController:infoController animated:YES];
This example assumes that you have a navigation controller in order to return to the previous view. You can of course also use presentViewController:animated:completion:. The main point is to have your storyboard instantiate your target view controller using the target view controller's ID.
func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
print("Push notification received: \(data)")
if let info = data["aps"] as? Dictionary<String, AnyObject> {
let alertMsg = info["alert"] as! String
print(alertMsg)
switch application.applicationState {
case .active:
print("do stuff in case App is active")
case .background:
print("do stuff in case App is in background")
// navigateToChatDetailViewControler(pushdata: data)
case .inactive:
print("do stuff in case App is inactive")
// navigateToChatDetailViewControler(pushdata: data)
}
}
}

The accuracy of this section is disputed with respect to later versions of Python. In CPython 2.5, string concatenation is fairly fast, although this may not apply likewise to other Python implementations. See ConcatenationTestCode for a discussion.
You can do it with few lines of CSS code. You can align all div's which you want to appear next to each other to right.
<div class="div_r">First Element</div>
<div class="div_r">Second Element</div>
<style>
.div_r{
float:right;
color:red;
}
</style>
This is my solution, although for sure you can use a lot of modules that give you the object as a promise or similar. Anyway, you were missing another callback
function getData(callbackData){
var http = require('http');
var str = '';
var options = {
host: 'www.random.org',
path: '/integers/?num=1&min=1&max=10&col=1&base=10&format=plain&rnd=new'
};
callback = function(response) {
response.on('data', function (chunk) {
str += chunk;
});
response.on('end', function () {
console.log(str);
callbackData(str);
});
//return str;
}
var req = http.request(options, callback).end();
// These just return undefined and empty
console.log(req.data);
console.log(str);
}
somewhere else
getData(function(data){
// YOUR CODE HERE!!!
})
I also had issues with OS X Yosemite on a fresh install of Android Studio.
My situation was that I was using a VPN. In the preferences, I ended up setting the HTTP Proxy setting to detect automatically after trying running it as sudo and setting a static proxy setting, but neither worked. I was able to download successfully after that. Hope this helps someone with a similar situation (VPN).
Ah, the dreaded loose comparison operator strikes again. Never use it. Always use strict comparison, === or !== instead.
Bonus fact: 0 == ''
test ! -f README.md || echo 'Support OpenSource!' >> README.md
"If README.md does not exist, do nothing (and exit successfully). Otherwise, append text to the end."
If you use &&
instead of ||
then you generate an error when the file doesn't exist:
Makefile:42: recipe for target 'dostuff' failed
make: *** [dostuff] Error 1
As the character (-) is referred to as "hyphen" or "dash", it seems more natural to name this "dash-case", or "hyphen-case" (less frequently used).
As mentioned in Wikipedia, "kebab-case" is also used. Apparently (see answer) this is because the character would look like a skewer... It needs some imagination though.
Used in lodash lib for example.
Recently, "dash-case" was used by
I want to add my 2 cents. I am far from being a database expert, but I've recently read up a bit on this topic; enough for me to try and give an ELI5. So, here's may layman's explanation.
I understand it as such that an index is like a mini-mirror of your table, pretty much like an associative array. If you feed it with a matching key then you can just jump to that row in one "command".
But if you didn't have that index / array, the query interpreter must use a for-loop to go through all rows and check for a match (the full-table scan).
Having an index has the "downside" of extra storage (for that mini-mirror), in exchange for the "upside" of looking up content faster.
Note that (in dependence of your db engine) creating primary, foreign or unique keys automatically sets up a respective index as well. That same principle is basically why and how those keys work.
Primitive numeric types are useful for storing single values in memory. But when dealing with calculation using double and float types, there is a problems with the rounding.It happens because memory representation doesn't map exactly to the value. For example, a double value is supposed to take 64 bits but Java doesn't use all 64 bits.It only stores what it thinks the important parts of the number. So you can arrive to the wrong values when you adding values together of the float or double type.

For the SQL Server Owner, you should be able to use:
select suser_sname(owner_sid) as 'Owner', state_desc, *
from sys.databases
For a list of SQL Users:
select * from master.sys.server_principals
Ref. SQL Server Tip: How to find the owner of a database through T-SQL
Something like this should work (untested code warning):
<?php
$html = '<p style="asd">qwe</p><br /><p class="qwe">qweqweqwe</p>';
$domd = new DOMDocument();
libxml_use_internal_errors(true);
$domd->loadHTML($html);
libxml_use_internal_errors(false);
$domx = new DOMXPath($domd);
$items = $domx->query("//p[@style]");
foreach($items as $item) {
$item->removeAttribute("style");
}
echo $domd->saveHTML();
it will have some effect on an object.... query for the result of the effect. If it has no visible effect its not worth unit testing!
You can use the Dictionary
data type in python. It's very very similar to the hash—and it also supports nesting, similar to the to nested hash.
Example:
dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'}
dict['Age'] = 8; # update existing entry
dict['School'] = "DPS School" # Add new entry
print ("dict['Age']: ", dict['Age'])
print ("dict['School']: ", dict['School'])
For more information, please reference this tutorial on the dictionary data type.
For those that want it ISO 8601 compliant, since the other solutions do not have the T
separator nor the time offset (except Meistro's answer):
from datetime import datetime, timezone
result = datetime.fromtimestamp(1463288494, timezone.utc).isoformat('T', 'microseconds')
print(result) # 2016-05-15T05:01:34.000000+00:00
Note, I use fromtimestamp
because if I used utcfromtimestamp
I would need to chain on .astimezone(...)
anyway to get the offset.
If you don't want to go all the way to microseconds
you can choose a different unit with the
isoformat() method.
It don't create normally; you need to add it by yourself.
After adding Global.asax
by
You need to add a class
Inherit the newly generated by System.Web.HttpApplication
and copy all the method created Global.asax
to Global.cs
and also add an inherit attribute to the Global.asax file.
Your Global.asax will look like this: -
<%@ Application Language="C#" Inherits="Global" %>
Your Global.cs in App_Code
will look like this: -
public class Global : System.Web.HttpApplication
{
public Global()
{
//
// TODO: Add constructor logic here
//
}
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
}
/// Many other events like begin request...e.t.c, e.t.c
}

You can also use psql console to execute \copy without need to send file to Postgresql server machine. The command is the same:
\copy mytable [ ( column_list ) ] FROM '/path/to/csv/file' WITH CSV HEADER
The value
attribute of a checkbox
is what you set by:
<input type='checkbox' name='test' value='1'>
So when someone checks that box, the server receives a variable named test
with a value
of 1
- what you want to check for is not the value
of it (which will never change, whether it is checked or not) but the checked
status of the checkbox.
So, if you replace this code:
if (arrChecks[i].value == "on")
{
arrChecks[i].checked = 1;
} else {
arrChecks[i].checked = 0;
}
With this:
arrChecks[i].checked = !arrChecks[i].checked;
It should work. You should use true
and false
instead of 0
and 1
for this.
Check that you closed your class.
For example, if you have controller class with methods, and by accident you delete the final bracket, which close whole class, you will get this error.
class someControler{
private $varr;
public $varu;
..
public function method {
..
}
..
}// if you forget to close the controller, you will get the error
List<string> chunks = new List<string>();
var longString = new string('s', 3000);
var chunkLength = 1273;
var ratio = (double)longString.Length / chunkLength;
var countOfChunks = Convert.ToByte(Math.Round(ratio, MidpointRounding.ToPositiveInfinity));
for (byte i = 0; i < countOfChunks; i++)
{
var remainingLength = longString.Length - chunkLength * i;
if (chunkLength > remainingLength)
chunks.Add(longString.Substring(i * chunkLength, remainingLength));
else
chunks.Add(longString.Substring(i * chunkLength, chunkLength));
}
for(j = 0; j<=90; j++){}
j++ means j=j+1, j value already 0 now we are adding 1 so now the sum value of j+1 became 1, finally we are overriding the j value(0) with the sum value(1) so here we are overriding the j value by j+1. So each iteration j value will be incremented by 1.
for(j = 0; j<=90; j+3){}
Here j+3 means j value already 0 now we are adding 3 so now the sum value of j+3 became 3 but we are not overriding the existing j value. So that JVM asking the programmer, you are calculating the new value but where you are assigning that value to a variable(i.e j). That's why we are getting the compile-time error " invalid AssignmentOperator ".
If we want to increment j value by 3 then we can use any one of the following way.
for (int j=0; j<=90; j+=3) --> here each iteration j value will be incremented by 3.
for (int j=0; j<=90; j=j+3) --> here each iteration j value will be incremented by 3.
Using array_key_exists() on objects is Deprecated in php 7.4
Instead either isset() or property_exists() should be used

One recipe that I have used (described here: Co-Director Network Data Files in GEXF and JSON from OpenCorporates Data via Scraperwiki and networkx ) runs as follows:
The networkx JSON exporter takes the form:
from networkx.readwrite import json_graph
import json
print json.dumps(json_graph.node_link_data(G))
Alternatively you can export the network as a GEXF XML file and then import this representation into the sigma.js Javascript visualisation library.
from xml.etree.cElementTree import tostring
writer=gf.GEXFWriter(encoding='utf-8',prettyprint=True,version='1.1draft')
writer.add_graph(G)
print tostring(writer.xml)
If you only want those tags which exist on the remote, simply delete all your local tags:
$ git tag -d $(git tag)
And then fetch all the remote tags:
$ git fetch --tags
You can call java myProg arg1 arg2 ...
:
public static void main (String args[]) {
BufferedReader in = new BufferedReader(new FileReader(args[0]));
}
To subset by column index (to avoid typing their names) you can do
dt[, .SD, .SDcols = -c(1:3, 5L)]

It actually depends on what is being used to print the result. Usually, the result is the same, just as you say -
Historically carriage return is supposed to do about what the home
button does: return the caret to the start of the line.
\n
is supposed to give you a new line but not move the caret.
If you think about old printers, you're pretty much thinking how the original authors of the character sets were thinking. It's a different operation moving the paper feeder and moving the caret. These two characters express that difference.
OpenSSL is quite difficult. It's easy to accidentally throw away all your security by not doing negotiation exactly right. (Heck, I've been personally bitten by a bug where curl wasn't reading the OpenSSL alerts exactly right, and couldn't talk to some sites.)

How about this: Collections.list(Enumeration e) returns an ArrayList<T>
In order to approach to Modular design pattern, you need to understand these concept first:
Immediately-Invoked Function Expression (IIFE):
(function() {
// Your code goes here
}());
There are two ways you can use the functions. 1. Function declaration 2. Function expression.
Here are using function expression.
What is namespace? Now if we add the namespace to the above piece of code then
var anoyn = (function() {
}());
What is closure in JS?
It means if we declare any function with any variable scope/inside another function (in JS we can declare a function inside another function!) then it will count that function scope always. This means that any variable in outer function will be read always. It will not read the global variable (if any) with the same name. This is also one of the objective of using modular design pattern avoiding naming conflict.
var scope = "I am global";
function whatismyscope() {
var scope = "I am just a local";
function func() {return scope;}
return func;
}
whatismyscope()()
Now we will apply these three concepts I mentioned above to define our first modular design pattern:
var modularpattern = (function() {
// your module code goes here
var sum = 0 ;
return {
add:function() {
sum = sum + 1;
return sum;
},
reset:function() {
return sum = 0;
}
}
}());
alert(modularpattern.add()); // alerts: 1
alert(modularpattern.add()); // alerts: 2
alert(modularpattern.reset()); // alerts: 0
The objective is to hide the variable accessibility from the outside world.
Hope this helps. Good Luck.

if this is what you want .
The error is coming from $userRecord->email
. You need to use the ->get()
or ->first()
methods when calling from the database otherwise you're only getting the Eloquent\Builder
object rather than an Eloquent\Collection
The ->first()
method is pretty self-explanatory, it will return the first row found. ->get()
returns all the rows found
$userRecord = Model::where('email', '=', $email)->where('password', '=', $password)->get();
echo "First name: " . $userRecord->email;
Sometimes size
"picks the wrong one" and returns a hash (which is what count
would do)
In that case, use length
to get an integer instead of hash.
Yes, just delete the branch by running git push origin :branchname
. To fix a new issue later, branch off from master again.
Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.
You can use concatenation to get several columns at once:
SELECT x,
regexp_substr(yz, '[^^]+', 1, 1) y,
regexp_substr(yz, '[^^]+', 1, 2) z
FROM (SELECT a.x,
(SELECT b.y || '^' || b.z yz
FROM b
WHERE b.v = a.v)
yz
FROM a)
You would need to make sure that no column in the list contain the separator character.
You could also use SQL objects:
CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
SELECT x,
v.yz.y y,
v.yz.z z
FROM (SELECT a.x,
(SELECT b_obj(y, z) yz
FROM b
WHERE b.v = a.v)
yz
FROM a) v
Try this general approach:
import re
my_string="hello python world , i'm a beginner "
p = re.compile("world(.*)")
print (p.findall(my_string))
#[" , i'm a beginner "]
So with the code you have provided.
var bytes = Convert.FromBase64String(resizeImage.Content);
using (var imageFile = new FileStream(filePath, FileMode.Create))
{
imageFile.Write(bytes ,0, bytes.Length);
imageFile.Flush();
}
You could use a navigation property if its available. It produces an inner join in the SQL.
from s in db.Services
where s.ServiceAssignment.LocationId == 1
select s
Have you tried the following:
SELECT ID, COUNT(*), max(date)
FROM table
GROUP BY ID;
<div>
<img class="crop" src="http://lorempixel.com/500/200"/>
</div>
<img src="http://lorempixel.com/500/200"/>

width: 200px;
height: 200px;
overflow: hidden;
margin: 10px;

position: absolute;

Your problem is you have the b
in the open
flag.
The flag rt
(read, text) is the default, so, using the context manager, simply do this:
with open('sample.csv') as ifile:
read = csv.reader(ifile)
for row in read:
print (row)
The context manager means you don't need generic error handling (without which you may get stuck with the file open, especially in an interpreter), because it will automatically close the file on an error, or on exiting the context.
The above is the same as:
with open('sample.csv', 'r') as ifile:
...
or
with open('sample.csv', 'rt') as ifile:
...
I put together a little type check utility inspired by the above correct answers:
thetypeof = function(name) {
let obj = {};
obj.object = 'object Object'
obj.array = 'object Array'
obj.string = 'object String'
obj.boolean = 'object Boolean'
obj.number = 'object Number'
obj.type = Object.prototype.toString.call(name).slice(1, -1)
obj.name = Object.prototype.toString.call(name).slice(8, -1)
obj.is = (ofType) => {
ofType = ofType.toLowerCase();
return (obj.type === obj[ofType])? true: false
}
obj.isnt = (ofType) => {
ofType = ofType.toLowerCase();
return (obj.type !== obj[ofType])? true: false
}
obj.error = (ofType) => {
throw new TypeError(`The type of ${name} is ${obj.name}: `
+`it should be of type ${ofType}`)
}
return obj;
};
example:
if (thetypeof(prop).isnt('String')) thetypeof(prop).error('String')
if (thetypeof(prop).is('Number')) // do something
Personally i prefer the format function, allows you to simply change the date part very easily.
declare @format varchar(100) = 'yyyy/MM/dd'
select
format(the_date,@format),
sum(myfield)
from mytable
group by format(the_date,@format)
order by format(the_date,@format) desc;
Non-privileged user (not root) can't open a listening socket on ports below 1024.
I like to use
git stash
This stores all uncommitted changes in the stash. If you want to discard these changes later just git stash drop
(or git stash pop
to restore them).
Though this is technically not the "proper" way to discard changes (as other answers and comments have pointed out).
SourceTree: On the top bar click on icon 'Stash', type its name and create. Then in left vertical menu you can "show" all Stash and delete in right-click menu. There is probably no other way in ST to discard all files at once.
In Python 3.3+:
from datetime import datetime, timezone
def utc_to_local(utc_dt):
return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)
In Python 2/3:
import calendar
from datetime import datetime, timedelta
def utc_to_local(utc_dt):
# get integer timestamp to avoid precision lost
timestamp = calendar.timegm(utc_dt.timetuple())
local_dt = datetime.fromtimestamp(timestamp)
assert utc_dt.resolution >= timedelta(microseconds=1)
return local_dt.replace(microsecond=utc_dt.microsecond)
Using pytz
(both Python 2/3):
import pytz
local_tz = pytz.timezone('Europe/Moscow') # use your local timezone name here
# NOTE: pytz.reference.LocalTimezone() would produce wrong result here
## You could use `tzlocal` module to get local timezone on Unix and Win32
# from tzlocal import get_localzone # $ pip install tzlocal
# # get local timezone
# local_tz = get_localzone()
def utc_to_local(utc_dt):
local_dt = utc_dt.replace(tzinfo=pytz.utc).astimezone(local_tz)
return local_tz.normalize(local_dt) # .normalize might be unnecessary
def aslocaltimestr(utc_dt):
return utc_to_local(utc_dt).strftime('%Y-%m-%d %H:%M:%S.%f %Z%z')
print(aslocaltimestr(datetime(2010, 6, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime(2010, 12, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime.utcnow()))

Note: it takes into account DST and the recent change of utc offset for MSK timezone.
I don't know whether non-pytz solutions work on Windows.
Since you know the chars are lower case, you can subtract the according ASCII value to make them uppercase:
char a = 'a';
a -= 32;
System.out.println("a is " + a); //a is A
Here is an ASCII table for reference
You need to use the group(int) of your matcher - group(0) is the entire match, and group(1) is the first group you marked. In the example you specify, group(1) is what comes after "sentence".
I want columns One and Two to shrink/grow to fit rather than being fixed.
Have you tried: flex-basis: auto
or this:
flex: 1 1 auto
, which is short for:
flex-grow: 1
(grow proportionally)flex-shrink: 1
(shrink proportionally)flex-basis: auto
(initial size based on content size)or this:
main > section:first-child {
flex: 1 1 auto;
overflow-y: auto;
}
main > section:nth-child(2) {
flex: 1 1 auto;
overflow-y: auto;
}
main > section:last-child {
flex: 20 1 auto;
display: flex;
flex-direction: column;
}

I tried to push to my own hosted bonobo-git server, and did not realise, that the http.postbuffer meant the project directory ...
so just for other confused ones:
why? In my case, I had large zip files with assets and some PSDs pushed as well - to big for the buffer I guess.
How to do this http.postbuffer: execute that command within your project src directory, next to the .git folder, not on the server.
be aware, large temp (chunk) files will be created of that buffer size.
Note: Just check your largest files, then set the buffer.
You can use the version in Windows SDK but sometimes it might not be the same version of the .NET Framework your using, getting you the following error:
Microsoft (R) .NET Global Assembly Cache Utility. Version 3.5.21022.8 Copyright (c) Microsoft Corporation. All rights reserved. Failure adding assembly to the cache: This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
In .NET 4.0 you'll need to search inside Microsoft SDK v8.0A, e.g.: C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools (in my case I only have the 32 bit version installed by Visual Studio 2012).
You cannot assign expressions with types such as List<NavigableMap<String,String>>
to the first.
(If you want to know why you can't assign List<String>
to List<Object>
see a zillion other questions on SO.)
Subset is a very slow function , and I personally find it useless.
I assume you have a data.frame, array, matrix called Mat
with A
, B
, C
as column names; then all you need to do is:
In the case of one condition on one column, lets say column A
Mat[which(Mat[,'A'] == 10), ]
In the case of multiple conditions on different column, you can create a dummy variable. Suppose the conditions are A = 10
, B = 5
, and C > 2
, then we have:
aux = which(Mat[,'A'] == 10)
aux = aux[which(Mat[aux,'B'] == 5)]
aux = aux[which(Mat[aux,'C'] > 2)]
Mat[aux, ]
By testing the speed advantage with system.time
, the which
method is 10x faster than the subset
method.
In regards to your code, see @Coulton. You'll need to use JavaScript.
Checkout either FitText (it does work in IE, they just ballsed their site somehow) or BigText.
FitText will allow you to scale some text in relation to the container it is in, while BigText is more about resizing different sections of text to be the same width within the container.
BigText will set your string to exactly the width of the container, whereas FitText is less pixel perfect. It starts by setting the font-size at 1/10th of the container element's width. It doesn't work very well with all fonts by default, but it has a setting which allows you to decrease or increase the 'power' of the re-size. It also allows you to set a min and max font-size. It will take a bit of fiddling to get working the first time, but does work great.
http://marabeas.io <- playing with it currently here. As far as I understand, BigText wouldn't work in my context at all.
For those of you using Angularjs, here's an Angular version of FitText I've made.
Here's a LESS mixin you can use to make @humanityANDpeace's solution a little more pretty:
@mqIterations: 19;
.fontResize(@i) when (@i > 0) {
@media all and (min-width: 100px * @i) { body { font-size:0.2em * @i; } }
.fontResize((@i - 1));
}
.fontResize(@mqIterations);
And an SCSS version thanks to @NIXin!
$mqIterations: 19;
@mixin fontResize($iterations) {
$i: 1;
@while $i <= $iterations {
@media all and (min-width: 100px * $i) { body { font-size:0.2em * $i; } }
$i: $i + 1;
}
}
@include fontResize($mqIterations);
Another useful thing to do with numpy.histogram
is to plot the output as the x and y coordinates on a linegraph. For example:
arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()
This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.

In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime()
gives you the mentioned milliseconds).
In your solution:
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();
long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);
you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.
Another possible solution would be to utilise the static fields of the Calendar
class:
//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);
Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.
In my case I had an image in different folders (with same name) for supporting different dpi and device sizes. All images had same name except one of them. It was mistyped and once I renamed it like other names, it resolved my issue.
The issue here is that you've initialized your array, but not its elements; they are all null. So if you try to reference houses[0]
, it will be null
.
Here's a great little helper method you could write for yourself:
T[] InitializeArray<T>(int length) where T : new()
{
T[] array = new T[length];
for (int i = 0; i < length; ++i)
{
array[i] = new T();
}
return array;
}
Then you could initialize your houses
array as:
GameObject[] houses = InitializeArray<GameObject>(200);

I use Xamarin with Visual Studio, and I prefer to move only some large android to another directory with(copy these folders to destination before create hardlinks):
mklink \J "C:\Users\yourUser\.android" "E:\yourFolder\.android"

Basically, you use System.Reflection
to get a reference to the current Assembly. Then, you use GetManifestResourceStream()
.

StreamReader _textStreamReader;

Use FileUtils to handle all these headaches.
Edit: For example, use below code to write to a file, this method will 'checking and creating the parent directory if it does not exist'.
openOutputStream(File file [, boolean append])
Try:
sheet 2 a1 =vlookup(sheet2a1,sheet1$a$1:$b$6,2)
Then drag it down.
It should work.
You can augment String to implement these behaviors as methods, as in:
String.prototype.killWhiteSpace = function() {
return this.replace(/\s/g, '');
};
String.prototype.reduceWhiteSpace = function() {
return this.replace(/\s+/g, ' ');
};
This now enables you to use the following elegant forms to produce the strings you want:
"Get rid of my whitespaces.".killWhiteSpace();
"Get rid of my extra whitespaces".reduceWhiteSpace();
I read all answers here, but cannot get
echo $this->db->get_compiled_select();
to work, It gave me error like,
Call to protected method CI_DB_active_record::_compile_select() from context 'Welcome'in controllers on line xx
So i removed protected
from the below line from file \system\database\DB_active_rec.php
and it worked
protected function _compile_select($select_override = FALSE)
$ens = $em->getRepository('AcmeBinBundle:Marks')
->findBy(
array(),
array('id' => 'ASC')
);
When you have replace: true
you get the following piece of DOM:
<div ng-controller="Ctrl" class="ng-scope">
<div class="ng-binding">hello</div>
</div>
whereas, with replace: false
you get this:
<div ng-controller="Ctrl" class="ng-scope">
<my-dir>
<div class="ng-binding">hello</div>
</my-dir>
</div>
So the replace
property in directives refer to whether the element to which the directive is being applied (<my-dir>
in that case) should remain (replace: false
) and the directive's template should be appended as its child,
OR
the element to which the directive is being applied should be replaced (replace: true
) by the directive's template.
In both cases the element's (to which the directive is being applied) children will be lost. If you wanted to perserve the element's original content/children you would have to translude it. The following directive would do it:
.directive('myDir', function() {
return {
restrict: 'E',
replace: false,
transclude: true,
template: '<div>{{title}}<div ng-transclude></div></div>'
};
});
In that case if in the directive's template you have an element (or elements) with attribute ng-transclude
, its content will be replaced by the element's (to which the directive is being applied) original content.
See example of translusion http://plnkr.co/edit/2DJQydBjgwj9vExLn3Ik?p=preview
See this to read more about translusion.
None of the answers here work correctly for Chrome OS multiple displays, or soon-to-come Foldables.
When looking for the current configuration, always use the configuration from your current activity in
getResources().getConfiguration()
. Do not use the configuration from your background activity or the one from the system resource. The background activity does not have a size, and the system's configuration may contain multiple windows with conflicting sizes and orientations, so no usable data can be extracted.
So the answer is
val config = context.getResources().getConfiguration()
val (screenWidthPx, screenHeightPx) = config.screenWidthDp.dp to config.screenHeightDp.dp
put x=0 outside the for loop that is the problem
I was gone through same problem solved after lot efforts. It is because of npm version is not compatible with gprc version. So we need to update the npm.
npm update

function getParent(event)
{
return event.target.parentNode;
}
Examples: 1.
document.body.addEventListener("click", getParent, false);
returns the parent element of the current element that you have clicked.
- If you want to use inside any function then pass your event and call the function like this :
function yourFunction(event){ var parentElement = getParent(event); }
This is what I came out with.

Another C# example. I just made an extension method for it.

return table.FindElements(By.XPath("./tbody/tr"))[rowIndex].FindElements(By.XPath("./td"))[columnIndex].Text;
}
Keeping the NAT adapter and adding a second host-only adapter works amazing, and is crucial for laptops (where the external network always changes).
http://muffinresearch.co.uk/archives/2010/02/08/howto-ssh-into-virtualbox-3-linux-guests/
Remember to create a host-only network in virtualbox itself (GUI -> settings -> network), otherwise you can't create the host-only interface on the guest.
Actually I found the real Root Cause for this issue, by going to add each .jar
files manually one by one, because the following answer within the same thread, suggests you to do so.
Cause:
You know as we are humans, we are really lazy creatures and that's why we have an option to "Select All" and also shortcut keys to perform that.
So when I have to add around 30+ jar files for a PDF generation required app, I did go in this way,
Right Click on Project -> Properties -> Java Build Path
So you have two options:
Select only the JAR files wherever you want and don't be too lazy to add text and other types of files. or,
Select all files within a specific folder where you wanna add JARs from, and then remove one by one, which are non-JAR files.
Note:
If you have added any of non-JAR files to the project in that way as you were trying to add "libraries", it will show you something like the following:
and keep trying to compile and at the end, it will give you the following error:
Error: Could not find or load the main class er.waterapp.some.MainFileGivenByConfigaration
So this is it!!! Hope I may have had the chance to help some one out there and also save him a lot of time. :-)

Get your object's constructor function and then inspect its name property.
myObj.constructor.name
Returns "myClass".
This code should work properly to get the current date from the calendar.
String today=getCurrentDay(); //function
driver.findElement(By.xpath("here xpath of textbox")).click();
Thread.sleep(5000);
WebElement dateWidgetForm= driver.findElement(By.xpath("here xpath of calender"));
List<WebElement> columns = dateWidgetForm.findElements(By.tagName("td"));
for (WebElement cell: columns) {
String z=cell.getAttribute("class").toString();
if(z.equalsIgnoreCase("day")){
if (cell.getText().equals(today)) {
cell.click();
break;
}
}
private String getCurrentDay() {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
//Get Current Day as a number
int todayInt = calendar.get(Calendar.DAY_OF_MONTH);
System.out.println("Today Int: " + todayInt +"\n");
//Integer to String Conversion
String todayStr = Integer.toString(todayInt);
return todayStr;
}
Let's try this
select convert(varchar, getdate(), 108)
Just try a few moment ago
I think you would need to add something like PHP into the equation. PHP to interact with the database and then you could make AJAX calls with Javascript.
Through the original question is not exactly about the locale itself all other locale related questions are referencing to this one. That's why I wanted to clarify the issue here. I used this question as a starting point for my own locale switching code and found out that the method is not exactly correct. It works, but only until any configuration change (e.g. screen rotation) and only in that particular Activity. Playing with a code for a while I have ended up with the following approach:
I have extended android.app.Application and added the following code:
public class MyApplication extends Application
{
private Locale locale = null;
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
if (locale != null)
{
newConfig.locale = locale;
Locale.setDefault(locale);
getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
}
}
@Override
public void onCreate()
{
super.onCreate();
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
Configuration config = getBaseContext().getResources().getConfiguration();
String lang = settings.getString(getString(R.string.pref_locale), "");
if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
{
locale = new Locale(lang);
Locale.setDefault(locale);
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
}
}
}
This code ensures that every Activity will have custom locale set and it will not be reset on rotation and other events.
I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed: the language changed correctly on Activity restart, but number formats and other locale properties were not applied until full application restart.
AndroidManifest.xml
Don't forget to add android:configChanges="layoutDirection|locale"
to every activity at AndroidManifest, as well as the android:name=".MyApplication"
to the <application>
element.
Another method is to place a png behind the UILabel. I have views with several labels that overlay a single background png that has all the artwork for the individual labels.
In your git dir, suppose you have sync all changes.
rm -rf .git
rm -rf .gitmodules
Then do:
git init
git submodule add url_to_repo projectfolder
If you want to filter only items that are less than 7 days old then you just use
Filter
Created
is greater than or equal to
[Today]-7
Note - the screenshot is incorrect.
[Today] is fully supported in view filters in 2007 and onwards (just keep the spaces out!) and you only need to muck around with calculated columns in 2003.
I don't like very much iterator's semantic, please consider this as an option. It's also safer as you publish less of your internal state
private Map<String, String> JSONtoMAP(String jsonString) {
JSONObject json = new JSONObject(jsonString);
Map<String, String> outMap = new HashMap<String, String>();
for (String curKey : (Set<String>) json.keySet()) {
outMap.put(curKey, json.getString(curKey));
}
return outMap;
}
Use iloc and select all rows (:
) against the last column (-1
):
df.iloc[:,-1:]
In C# you can call a method of any ancestor like this:
public class A
internal virtual void foo()
...
public class B : A
public new void foo()
...
public class C : B
public new void foo() {
(this as A).foo();
}
Also you can do this in Delphi:
type
A=class
procedure foo;
...
B=class(A)
procedure foo; override;
...
C=class(B)
procedure foo; override;
...
A(objC).foo();
But in Java you can do such focus only by some gear. One possible way is:
class A {
int y=10;
void foo(Class X) throws Exception {
if(X!=A.class)
throw new Exception("Incorrect parameter of "+this.getClass().getName()+".foo("+X.getName()+")");
y++;
System.out.printf("A.foo(%s): y=%d\n",X.getName(),y);
}
void foo() throws Exception {
System.out.printf("A.foo()\n");
this.foo(this.getClass());
}
}
class B extends A {
int y=20;
@Override
void foo(Class X) throws Exception {
if(X==B.class) {
y++;
System.out.printf("B.foo(%s): y=%d\n",X.getName(),y);
} else {
System.out.printf("B.foo(%s) calls B.super.foo(%s)\n",X.getName(),X.getName());
super.foo(X);
}
}
}
class C extends B {
int y=30;
@Override
void foo(Class X) throws Exception {
if(X==C.class) {
y++;
System.out.printf("C.foo(%s): y=%d\n",X.getName(),y);
} else {
System.out.printf("C.foo(%s) calls C.super.foo(%s)\n",X.getName(),X.getName());
super.foo(X);
}
}
void DoIt() {
try {
System.out.printf("DoIt: foo():\n");
foo();
Show();
System.out.printf("DoIt: foo(B):\n");
foo(B.class);
Show();
System.out.printf("DoIt: foo(A):\n");
foo(A.class);
Show();
} catch(Exception e) {
//...
}
}
void Show() {
System.out.printf("Show: A.y=%d, B.y=%d, C.y=%d\n\n", ((A)this).y, ((B)this).y, ((C)this).y);
}
}
objC.DoIt() result output:
DoIt: foo():
A.foo()
C.foo(C): y=31
Show: A.y=10, B.y=20, C.y=31
DoIt: foo(B):
C.foo(B) calls C.super.foo(B)
B.foo(B): y=21
Show: A.y=10, B.y=21, C.y=31
DoIt: foo(A):
C.foo(A) calls C.super.foo(A)
B.foo(A) calls B.super.foo(A)
A.foo(A): y=11
Show: A.y=11, B.y=21, C.y=31
String a []=new String[1];
a[0].add("kk" );
a[1].add("pp");
Try this one...

If you're using SQL Server, you could add three calculated fields to your table:
Sales (saleID INT, amount INT, created DATETIME)
ALTER TABLE dbo.Sales
ADD SaleYear AS YEAR(Created) PERSISTED
ALTER TABLE dbo.Sales
ADD SaleMonth AS MONTH(Created) PERSISTED
ALTER TABLE dbo.Sales
ADD SaleDay AS DAY(Created) PERSISTED
and now you could easily group by, order by etc. by day, month or year of the sale:
SELECT SaleDay, SUM(Amount)
FROM dbo.Sales
GROUP BY SaleDay
Those calculated fields will always be kept up to date (when your "Created" date changes), they're part of your table, they can be used just like regular fields, and can even be indexed (if they're "PERSISTED") - great feature that's totally underused, IMHO.
Marc
In your jQuery code there is a comma after the backgroundPosition portion:
backgroundPosition: '-20px 0px',
However, when listing the various properties you want to change in the .animate() method (and similar methods), the last argument listed between curly braces should not have a comma after it. I can't say if that's why the background position isn't getting changed, but it is an error and one I'd suggest fixing.
UPDATE: In the limited testing I've done just now, entering purely numerical values (without "px") works for backgroundPosition in the .animate() method. In other words, this works:
backgroundPosition: '-20 0'
However, this does not:
backgroundPosition: '-20px 0'
Hope this helps.
To solve this, I have imported some JAR files in my project:
http://search.maven.org/remotecontent?filepath=javax/xml/bind/jaxb-api/2.3.0/jaxb-api-2.3.0.jar
http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-core/2.3.0/jaxb-core-2.3.0.jar
http://search.maven.org/remotecontent?filepath=com/sun/xml/bind/jaxb-impl/2.3.0/jaxb-impl-2.3.0.jar
First step get container id:
docker ps
This will show you something like
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1170fe9e9460 localhost:5000/python:env-7e847468c4d73a0f35e9c5164046ad88 "./run_notebook.sh" 26 seconds ago Up 25 seconds 0.0.0.0:8989->9999/tcp SLURM_TASK-303337_0
1170fe9e9460
is the container id in this case.
Second, enter the docker :
docker exec -it [container_id] bash
so in the above case:
docker exec -it 1170fe9e9460 bash
del *.*
will only delete files, but not subdirectories. To nuke the contents of a directory, you can use this script:
@echo off
setlocal enableextensions
if {%1}=={} goto :HELP
if {%1}=={/?} goto :HELP
goto :START
:HELP
echo Usage: %~n0 directory-name
echo.
echo Empties the contents of the specified directory,
echo WITHOUT CONFIRMATION. USE EXTREME CAUTION!
goto :DONE
:START
pushd %1 || goto :DONE
rd /q /s . 2> NUL
popd
:DONE
endlocal
The pushd
changes into the directory of which you want to delete the children. Then when rd
asks to delete the current directory and all sub directories, the deletion of the sub directories succeed, but the deletion of the current directory fails - because we are in it. This produces an error which 2> NUL
swallows. (2 being the error stream).
For getting key
var a = {"a":"1","b":"2"};
var keys = []
for(var k in a){
keys.push(k)
}
For getting value.
var a = {"a":"1","b":"2"};
var values = []
for(var k in a){
values.push(a[k]);
}
If you use ICU4J (http://icu-project.org/apiref/icu4j/)
Here is my code:
String charset = "ISO-8859-1"; //Default chartset, put whatever you want
byte[] fileContent = null;
FileInputStream fin = null;
//create FileInputStream object
fin = new FileInputStream(file.getPath());
/*
* Create byte array large enough to hold the content of the file.
* Use File.length to determine size of the file in bytes.
*/
fileContent = new byte[(int) file.length()];
/*
* To read content of the file in byte array, use
* int read(byte[] byteArray) method of java FileInputStream class.
*
*/
fin.read(fileContent);
byte[] data = fileContent;
CharsetDetector detector = new CharsetDetector();
detector.setText(data);
CharsetMatch cm = detector.detect();
if (cm != null) {
int confidence = cm.getConfidence();
System.out.println("Encoding: " + cm.getName() + " - Confidence: " + confidence + "%");
//Here you have the encode name and the confidence
//In my case if the confidence is > 50 I return the encode, else I return the default value
if (confidence > 50) {
charset = cm.getName();
}
}
Remember to put all the try-catch need it.
I hope this works for you.
First and foremost, I highly recommend you buy the PDF/E-Book from PHP Architect. It's US$20, but is the only straightforward "Here's how Magento works" resource I've been able to find. I've also started writing Magento tutorials at my own website.
Second, if you have a choice, and aren't an experienced programmer or don't have access to an experienced programmer (ideally in PHP and Java), pick another cart. Magento is well engineered, but it was engineered to be a shopping cart solution that other programmers can build modules on top of. It was not engineered to be easily understood by people who are smart, but aren't programmers.
Third, Magento MVC is very different from the Ruby on Rails, Django, CodeIgniter, CakePHP, etc. MVC model that's popular with PHP developers these days. I think it's based on the Zend model, and the whole thing is very Java OOP-like. There's two controllers you need to be concerned about. The module/frontName controller, and then the MVC controller.
Fourth, the Magento application itself is built using the same module system you'll be using, so poking around the core code is a useful learning tactic. Also, a lot of what you'll be doing with Magento is overriding existing classes. What I'm covering here is creating new functionality, not overriding. Keep this in mind when you're looking at the code samples out there.
I'm going to start with your first question, showing you how to setup a controller/router to respond to a specific URL. This will be a small novel. I might have time later for the model/template related topics, but for now, I don't. I will, however, briefly speak to your SQL question.
Magento uses an EAV database architecture. Whenever possible, try to use the model objects the system provides to get the information you need. I know it's all there in the SQL tables, but it's best not to think of grabbing data using raw SQL queries, or you'll go mad.
Final disclaimer. I've been using Magento for about two or three weeks, so caveat emptor. This is an exercise to get this straight in my head as much as it is to help Stack Overflow.
All additions and customizations to Magento are done through modules. So, the first thing you'll need to do is create a new module. Create an XML file in app/modules
named as follows
cd /path/to/store/app
touch etc/modules/MyCompanyName_HelloWorld.xml
<?xml version="1.0"?>
<config>
<modules>
<MyCompanyName_HelloWorld>
<active>true</active>
<codePool>local</codePool>
</MyCompanyName_HelloWorld>
</modules>
</config>
MyCompanyName is a unique namespace for your modifications, it doesn't have to be your company's name, but that the recommended convention my magento. HelloWorld
is the name of your module.
Now that the module file is in place, we'll need to let Magento know about it (and check our work). In the admin application
Now, we make sure that Magento knows about the module
If you can live with the performance slow down, you might want to turn off the application cache while developing/learning. Nothing is more frustrating then forgetting the clear out the cache and wondering why your changes aren't showing up.
Next, we'll need to setup a directory structure for the module. You won't need all these directories, but there's no harm in setting them all up now.
mkdir -p app/code/local/MyCompanyName/HelloWorld/Block
mkdir -p app/code/local/MyCompanyName/HelloWorld/controllers
mkdir -p app/code/local/MyCompanyName/HelloWorld/Model
mkdir -p app/code/local/MyCompanyName/HelloWorld/Helper
mkdir -p app/code/local/MyCompanyName/HelloWorld/etc
mkdir -p app/code/local/MyCompanyName/HelloWorld/sql
And add a configuration file
touch app/code/local/MyCompanyName/HelloWorld/etc/config.xml
and inside the configuration file, add the following, which is essentially a "blank" configuration.
<?xml version="1.0"?>
<config>
<modules>
<MyCompanyName_HelloWorld>
<version>0.1.0</version>
</MyCompanyName_HelloWorld>
</modules>
</config>
Oversimplifying things, this configuration file will let you tell Magento what code you want to run.
Next, we need to setup the module's routers. This will let the system know that we're handling any URLs in the form of
http://example.com/magento/index.php/helloworld
So, in your configuration file, add the following section.
<config>
<!-- ... -->
<frontend>
<routers>
<!-- the <helloworld> tagname appears to be arbitrary, but by
convention is should match the frontName tag below-->
<helloworld>
<use>standard</use>
<args>
<module>MyCompanyName_HelloWorld</module>
<frontName>helloworld</frontName>
</args>
</helloworld>
</routers>
</frontend>
<!-- ... -->
</config>
What you're saying here is "any URL with the frontName of helloworld ...
http://example.com/magento/index.php/helloworld
should use the frontName controller MyCompanyName_HelloWorld".
So, with the above configuration in place, when you load the helloworld page above, you'll get a 404 page. That's because we haven't created a file for our controller. Let's do that now.
touch app/code/local/MyCompanyName/HelloWorld/controllers/IndexController.php
Now try loading the page. Progress! Instead of a 404, you'll get a PHP/Magento exception
Controller file was loaded but class does not exist
So, open the file we just created, and paste in the following code. The name of the class needs to be based on the name you provided in your router.
<?php
class MyCompanyName_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action{
public function indexAction(){
echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here";
}
}
What we've just setup is the module/frontName controller.
This is the default controller and the default action of the module.
If you want to add controllers or actions, you have to remember that the tree first part of a Magento URL are immutable they will always go this way http://example.com/magento/index.php/frontName/controllerName/actionName
So if you want to match this url
http://example.com/magento/index.php/helloworld/foo
You will have to have a FooController, which you can do this way :
touch app/code/local/MyCompanyName/HelloWorld/controllers/FooController.php
<?php
class MyCompanyName_HelloWorld_FooController extends Mage_Core_Controller_Front_Action{
public function indexAction(){
echo 'Foo Index Action';
}
public function addAction(){
echo 'Foo add Action';
}
public function deleteAction(){
echo 'Foo delete Action';
}
}
Please note that the default controller IndexController and the default action indexAction can by implicit but have to be explicit if something come after it.
So http://example.com/magento/index.php/helloworld/foo
will match the controller FooController and the action indexAction and NOT the action fooAction of the IndexController. If you want to have a fooAction, in the controller IndexController you then have to call this controller explicitly like this way :
http://example.com/magento/index.php/helloworld/index/foo
because the second part of the url is and will always be the controllerName.
This behaviour is an inheritance of the Zend Framework bundled in Magento.
You should now be able to hit the following URLs and see the results of your echo statements
http://example.com/magento/index.php/helloworld/foo
http://example.com/magento/index.php/helloworld/foo/add
http://example.com/magento/index.php/helloworld/foo/delete
So, that should give you a basic idea on how Magento dispatches to a controller. From here I'd recommended poking at the existing Magento controller classes to see how models and the template/layout system should be used.
You need to create new file and copy contents from InputStream
to that file:
File file = //...
try(OutputStream outputStream = new FileOutputStream(file)){
IOUtils.copy(inputStream, outputStream);
} catch (FileNotFoundException e) {
// handle exception here
} catch (IOException e) {
// handle exception here
}
I am using convenient IOUtils.copy()
to avoid manual copying of streams. Also it has built-in buffering.
