I needed to know how to loop over enum values (was testing lots of permutations of several enums) and I found this to work well:
export enum Environment {
Prod = "http://asdf.com",
Stage = "http://asdf1234.com",
Test = "http://asdfasdf.example.com"
}
Object.keys(Environment).forEach((environmentKeyValue) => {
const env = Environment[environmentKeyValue as keyof typeof Environment]
// env is now equivalent to Environment.Prod, Environment.Stage, or Environment.Test
}

In VS 2012, just go to View > Class View...then you get the Class View GUI in the main tab area. Now, drag this over to the side dock and you have the exact same layout as you would in Eclipse.

I wanted to have this context menu work only when right clicking and holding the 'SHIFT' which is how the built in 'Open Command window here' context menu works.
However none of the provided solutions did that so I had to roll my own .reg
file - copy the below, save it as power-shell-here-on-shift.reg
and double click on it.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\shell\powershell]
@="Open PowerShell here"

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'
IDENTIFIED BY 'YOUR_PASS'
WITH GRANT OPTION;
FLUSH PRIVILEGES;
*.* = DB.TABLE
you can restrict user to specific database and specific table.
'root'@'%'
you can change root with any user you created and % is to allow all IP. You can restrict it by changing %.168.1.1 etc too.
If that doesn't resolve, then also modify my.cnf or my.ini and comment these lines
bind-address = 127.0.0.1
to #bind-address = 127.0.0.1
and
skip-networking
to #skip-networking
Raspberry Pi, I found bind-address configuration under \etc\mysql\mariadb.conf.d\50-server.cnf
You are placing your result in the RETURN
value instead of in the passed @r
value.
From MSDN
(RETURN) Is the integer value that is returned. Stored procedures can return an integer value to a calling procedure or an application.
ALTER procedure S_Comp(@str1 varchar(20),@r varchar(100) out) as
declare @str2 varchar(100)
set @str2 ='welcome to sql server. Sql server is a product of Microsoft'
if(PATINDEX('%'+@str1 +'%',@str2)>0)
SELECT @r = @str1+' present in the string'
else
SELECT @r = @str1+' not present'
DECLARE @r VARCHAR(100)
EXEC S_Comp 'Test', @r OUTPUT
SELECT @r
In my case it was the close() that was not executing due to unhandled exception.
void method() throws Exception {
FileInputStream fis = new FileInputStream(fileName);
parse(fis);
fis.close();
}
Assume exception is being thrown on the parse(), which is not handled in this method and therefore the file is not closed, down the road, the file is being deleted, and that delete statement fails, and do not delete.
So, instead I had the code like this, then it worked...
try {
parse(fis);
}
catch (Exception ex) {
fis.close();
throw ex;
}
so basic Java, which sometimes we overlook.
If you have a <script>
tag anywhere on your page (even in the HTML, even if it is an empty tag with a src
), then a transition
must be activated by some event (it won't fire automatically when the page loads).
Play around with this jsFiddle example:
HTML:
<p id="foo" name="bar">Hello, world!</p>
jQuery:
$(function() {
var name = $('#foo').attr('name');
alert(name);
console.log(name);
});
This uses jQuery's .attr() method to get value for the first element in the matched set.
While not specifically jQuery, the result is shown as an alert prompt and written to the browser's console.
With Linq...
string s = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
var count = s.Split(new[] {',', ':'}).Count(s => s == "true" );
You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.
perhaps a:
i=2
while i < n:
if something:
do something
i += 1
else:
do something else
i = 2 #restart the loop
I made an installation guide for Egit on Eclipse so I thought I would share it.
INSTALL EGIT plugin in eclispe which is pretty easy. If EGit is missing in your Eclipse installation, you can install it via the Eclipse Update Manager via: Help ? Install new Software. EGit can be installed from the following URL: http://download.eclipse.org/egit/updates Under Eclipse Git Team Provider, tick ONLY "Eclipse EGit" and then download the plugin.
CONNECT TO YOUR LOCAL REPOSITORY. I right clicked on the project, selected "team > share project" and then ticked "use or create repository"
GIT IGNORE. Mark the "bin" folder as "ignored by Git", either by right-clicking on it and selecting Team > Ignore or by creating a .gitignore file. My file was generated for me, I just had to make it visible. Here's how in eclipse: In your package explorer, pull down the menu and select "Filters ...". You can adjust what types of files are shown/hidden there.
IDENTIFY YOURSELF. Click Preferences > Team > Git > Configuration and make sure your name & email are there so we know which user committed/pushed what.
NOW YOU ARE READY TO ADD/COMMIT/PUSH/PULL files with the plugin!
PHP provides two types of array.
normal array : This array is dynamic.
SplFixedArray : this is a standard php library which provides the ability to create array of fix size.
I think, below procedure help you to what you are looking for.
CREATE PROCEDURE [dbo].[FindEmployeeRecord]
@EmployeeID nvarchar(Max)
AS
BEGIN
DECLARE @sqLQuery VARCHAR(MAX)
Declare @AnswersTempTable Table
(
EmpId int,
EmployeeName nvarchar (250),
EmployeeAddress nvarchar (250),
PostalCode nvarchar (50),
TelephoneNo nvarchar (50),
Email nvarchar (250),
status nvarchar (50),
Sex nvarchar (50)
)
Set @sqlQuery =
'select e.EmpId,e.EmployeeName,e.Email,e.Sex,ed.EmployeeAddress,ed.PostalCode,ed.TelephoneNo,ed.status
from Employee e
join EmployeeDetail ed on e.Empid = ed.iEmpID
where Convert(nvarchar(Max),e.EmpId) in ('+@EmployeeId+')
order by EmpId'
Insert into @AnswersTempTable
exec (@sqlQuery)
select * from @AnswersTempTable
END
You can use this ng-switch:
<div ng-app ng-controller="friendsCtrl">
<label>Search: </label><input ng-model="searchText" type="text">
<div ng-init="filtered = (friends | filter:searchText)">
<h3>'Found '{{(friends | filter:searchText).length}} friends</h3>
<div ng-switch="(friends | filter:searchText).length">
<span class="ng-empty" ng-switch-when="0">No friends</span>
<table ng-switch-default>
<thead>
<tr>
<th>Name</th>
<th>Phone</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="friend in friends | filter:searchText">
<td>{{friend.name}}</td>
<td>{{friend.phone}}</td>
</tr>
</tbody>
</table>
</div>
If sleep.sh
has the shebang #!/bin/sh
and it has appropriate file permissions -- run chmod u+rx sleep.sh
to make sure and it is in $PATH
then your code should work as is:
import subprocess
rc = subprocess.call("sleep.sh")
If the script is not in the PATH then specify the full path to it e.g., if it is in the current working directory:
from subprocess import call
rc = call("./sleep.sh")
If the script has no shebang then you need to specify shell=True
:
rc = call("./sleep.sh", shell=True)
If the script has no executable permissions and you can't change it e.g., by running os.chmod('sleep.sh', 0o755)
then you could read the script as a text file and pass the string to subprocess
module instead:
with open('sleep.sh', 'rb') as file:
script = file.read()
rc = call(script, shell=True)
If you need a quick fix, simply add this before the line of your import:
// @ts-ignore
JsonPath jsonPathEvaluator = response.jsonPath();
return jsonPathEvaluator.get("user_id").toString();
I changed the python interpreter and it worked. On the keyboard, I pressed ctrl+shift+p. On the next window, I typed python: select interpreter, and there was an option to select the interpreter I wanted. From here, I chose the python interpreter located in my virtual environment.
In this case, it was my ~\DevFolder\myenv\scripts\python.exe
You can also like this:
$ nvm alias default lts/fermium
You can try this FLAG_ACTIVITY_REORDER_TO_FRONT
(the document describes exactly what you want to)
<input type='submit' value='Submit' onclick='this.form.action="somethingelse";' />
Or you can modify it from outside the form, with javascript the normal way:
document.getElementById('form_id').action = 'somethingelse';
When you go to "Application Settings -> Add Domain" It will ask to select login account, probably you are already on gmail account so it will show gmail account as well, but you should use Google Apps account where you have mapped your custom domain.
You should be able to access your windows system under the /mnt
directory. For example inside of bash, use this to get to your pictures directory:
cd /mnt/c/Users/<ubuntu.username>/Pictures
Hope this helps!
I recently had to create a solution with a fixed header group and a fixed first column. I split my table into div's and used jquery to capture window scrolling.
http://jsfiddle.net/TinT/EzXub/2346/
var prevTop = 0;
var prevLeft = 0;
$(window).scroll(function(event){
var currentTop = $(this).scrollTop();
var currentLeft = $(this).scrollLeft();
if(prevLeft !== currentLeft) {
prevLeft = currentLeft;
$('.header').css({'left': -$(this).scrollLeft()})
}
if(prevTop !== currentTop) {
prevTop = currentTop;
$('.leftCol').css({'top': -$(this).scrollTop() + 40})
}
});
jQuery 3
As of jQuery 3, removeAttr
does not set the corresponding property to false
anymore:
Prior to jQuery 3.0, using
.removeAttr()
on a boolean attribute such aschecked
,selected
, orreadonly
would also set the corresponding named property tofalse
. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.It is almost always a mistake to use
.removeAttr( "checked" )
on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases,.prop( "checked", false )
should be used instead.
Hence only .prop('checked',false)
is correct way when using this version.
Original answer (from 2011):
For attributes which have underlying boolean properties (of which checked
is one), removeAttr
automatically sets the underlying property to false
. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).
So, either will work... but the second example you gave (using prop
) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr
to do that.

foreach (array_map('trim', explode(',', $_SERVER[$key])) as $ip) {

return $ip;
}
}
}
}
}
Those two replaceAll
calls will always produce the same result, regardless of what x
is. However, it is important to note that the two regular expressions are not the same:
\\s
- matches single whitespace character \\s+
- matches sequence of one or more whitespace characters.In this case, it makes no difference, since you are replacing everything with an empty string (although it would be better to use \\s+
from an efficiency point of view). If you were replacing with a non-empty string, the two would behave differently.
Try the following command:
mysqladmin -h[hostname/localhost] -u[username] -p[password] drop [database]
I had the same problem as @mohitum007. In my case the developer of this App included an expiry date in it.
As workaround I set the date backwards to a past date (e.g. last month). Then I could install it and use it.
Also when I set the date back to normal, the already installed App didn't start up anymore. I contacted the company of this App to send me an updated version.
Sidenote: I found out that users from other Apps had the same problem but reversed: it won't install or start before a certain date.
A different approach, i.e: You could just do it 'the Angular way' and use ngModel
and skip document.getElementById('loginInput').value = '123';
altogether. Instead:
<input type="text" [(ngModel)]="username"/>
<input type="text" [(ngModel)]="password"/>
and in your component you give these values:
username: 'whatever'
password: 'whatever'
this will preset the username and password upon navigating to page.
If you don't mind logging the message also to syslog, the not_so_ugly way is:
logger -s $msg
The -s option means: "Output the message to standard error as well as to the system log."
For python2/3, Using below code snippet we can activate virtual env.
activate_this = "/home/<--path-->/<--virtual env name -->/bin/activate_this.py" #for ubuntu
activate_this = "D:\<-- path -->\<--virtual env name -->\Scripts\\activate_this.py" #for windows
with open(activate_this) as f:
code = compile(f.read(), activate_this, 'exec')
exec(code, dict(__file__=activate_this))
You can create an empty file whether it exists or not ...
new FileOutputStream("score.txt", false).close();
if you want to leave the file if it exists ...
new FileOutputStream("score.txt", true).close();
You will only get a FileNotFoundException if you try to create the file in a directory which doesn't exist.
Here's how you can do it:
public static class Extensions
{
public static IEnumerable<T> MyDistinct<T, V>(this IEnumerable<T> query,
Func<T, V> f,
Func<IGrouping<V,T>,T> h=null)
{
if (h==null) h=(x => x.First());
return query.GroupBy(f).Select(h);
}
}
This method allows you to use it by specifying one parameter like .MyDistinct(d => d.Name)
, but it also allows you to specify a having condition as a second parameter like so:
var myQuery = (from x in _myObject select x).MyDistinct(d => d.Name,
x => x.FirstOrDefault(y=>y.Name.Contains("1") || y.Name.Contains("2"))
);
N.B. This would also allow you to specify other functions like for example .LastOrDefault(...)
as well.
If you want to expose just the condition, you can have it even simpler by implementing it as:
public static IEnumerable<T> MyDistinct2<T, V>(this IEnumerable<T> query,
Func<T, V> f,
Func<T,bool> h=null
)
{
if (h == null) h = (y => true);
return query.GroupBy(f).Select(x=>x.FirstOrDefault(h));
}
In this case, the query would just look like:
var myQuery2 = (from x in _myObject select x).MyDistinct2(d => d.Name,
y => y.Name.Contains("1") || y.Name.Contains("2")
);
N.B. Here, the expression is simpler, but note .MyDistinct2
uses .FirstOrDefault(...)
implicitly.
Note: The examples above are using the following demo class
class MyObject
{
public string Name;
public string Code;
}
private MyObject[] _myObject = {
new MyObject() { Name = "Test1", Code = "T"},
new MyObject() { Name = "Test2", Code = "Q"},
new MyObject() { Name = "Test2", Code = "T"},
new MyObject() { Name = "Test5", Code = "Q"}
};
I actually wouldn't recommend using a2enmod
for php 5 or 7. I would use update-alternatives
. You can do sudo update-alternatives --config php
to set which system wide version of PHP you want to use. This makes your command line and apache versions work the same. You can read more about update-alternatives
on the man page.
overflow: auto;
or overflow: hidden;
should do it I think.
npm install -g npm@version
in which you want to downgrade
npm install -g [email protected]
That gist does describe what happend when you do a git fetch:
Obviously, change the github url to match your project's URL. It ends up looking like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
Now fetch all the pull requests:
$ git fetch origin
From github.com:joyent/node
* [new ref] refs/pull/1000/head -> origin/pr/1000
* [new ref] refs/pull/1002/head -> origin/pr/1002
* [new ref] refs/pull/1004/head -> origin/pr/1004
* [new ref] refs/pull/1009/head -> origin/pr/1009
...
To check out a particular pull request:
$ git checkout pr/999
Branch pr/999 set up to track remote branch pr/999 from origin.
Switched to a new branch 'pr/999'
You have various scripts listed in issues 259 to automate that task.
The git-extras project proposes the command git-pr
(implemented in PR 262)
git-pr
(1) -- Checks out a pull request locallySYNOPSIS
git-pr <number> [<remote>]
git-pr clean
DESCRIPTION
Creates a local branch based on a GitHub pull request number, and switch to that branch afterwards.
The name of the remote to fetch from. Defaults to
origin
.EXAMPLES
This checks out the pull request
226
fromorigin
:
$ git pr 226
remote: Counting objects: 12, done.
remote: Compressing objects: 100% (9/9), done.
remote: Total 12 (delta 3), reused 9 (delta 3)
Unpacking objects: 100% (12/12), done.
From https://github.com/visionmedia/git-extras
* [new ref] refs/pull/226/head -> pr/226
Switched to branch 'pr/226'
You could store it as an integer of the number of minutes past midnight:
eg.
0 = 00:00
60 = 01:00
252 = 04:12
You would however need to write some code to reconstitute the time, but that shouldn't be tricky.
I was struggling with the remote connection to Redis for some days. Finally I made it. Here is the full check list I put together to follow to get connected. Some of solutions are given in the answers above. Yet I wanted my answer to be a nano-wiki on the subject:) I added some useful links too.
$ redis-cli
127.0.0.1:6379>ping
PONG
127.0.0.1:6379>
See /etc/redis/redis.conf
config (this is default locaion for Ubuntu 18.04, you may have it in the different location):
# The following line should be commented
# requirepass <some pass if any>
# The following line should be uncommented
protected-mode no
# The following line should be commented
# bind 127.0.0.1 ::1
(here for Ubuntu 18.04) Check it allows for incoming internet traffic to go to port 6379
(the Redis default port)
# To check if it the port is open
$ sudo ufw status
Status: active
To Action From
-- ------ ----
...
6379/tcp ALLOW Anywhere
6379/tcp (v6) ALLOW Anywhere (v6)
...
# To open the port
$ sudo ufw allow 6379/tcp
Do not forget to restart the Redis service for changes to take effect and see it is running:
$ sudo systemctl restart redis.service
$ sudo systemctl status redis
from your command line use redis-cli
as if Redis server were on the remote server:
$ redis-cli -h <your-server-ip>
<your-server-ip>:6379> ping
PONG
<your-server-ip>:6379> exit
$
If you can ping-PONG your Redis server via your internet server connected as a remote server than the remote Redis connection works.
All the above makes your Redis data to be completely open to anybody from the internet.
To basically secure Redis use requirepass
and protected-mode yes
settings in Redis config (see above) and block the dangerous Redis commands (see the link above), for a deeper understanding see this article and Redis site security section ).
Some links to help How to install and secure Redis on Ubuntu 18.04 and how to setup Ubuntu 18.04 firewall.
Hope it helps.
The table just needs to have one column that does not allow nulls
try this
input[type='text']
{
background:red !important;
}
You forgot braces around the if block, and a semicolon between the statements in the block.
awk '{if($3 != 0) {a = ($3/$4); print $0, a;} else if($3==0) print $0, "-" }' file > out
I know that question is a bit old but
pipenv --venv
/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU
rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU
this works for me, sudo apt-get install libx11-dev
52e 1326 ERROR_LOGON_FAILURE
Returns when username is valid but password/credential is invalid. Will prevent most other errors from being displayed as noted.
http://ldapwiki.com/wiki/Common%20Active%20Directory%20Bind%20Errors
This works fine
<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
$con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
$con->query("SET time_zone = '+05:30'");
$con->query("SET @@session.time_zone = '+05:30'");
?>
curl
sends POST requests with the default content type of application/x-www-form-urlencoded
. If you want to send a JSON request, you will have to specify the correct content type header:
$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"
But that will only work if the server accepts json input. The .json
at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.
The reason you get a 401
and not some other error is probably because the server can't extract the auth_token
from your request.
Few open questions:-
we can modify the algo to support the negative number as follows:-
count = 0
while n != 0
if ((n % 2) == 1 || (n % 2) == -1
count += 1
n /= 2
return count
now to overcome the second problem we can write the algo like:-
int bit_count(int num)
{
int count=0;
while(num)
{
num=(num)&(num-1);
count++;
}
return count;
}
for complete reference see :
http://goursaha.freeoda.com/Miscellaneous/IntegerBitCount.html
It seems there are pros and cons to using either ??
or ?:
. The pro to using ?:
is that it evaluates false and null and "" the same. The con is that it reports an E_NOTICE if the preceding argument is null. With ??
the pro is that there is no E_NOTICE, but the con is that it does not evaluate false and null the same. In my experience, I have seen people begin using null and false interchangeably but then they eventually resort to modifying their code to be consistent with using either null or false, but not both. An alternative is to create a more elaborate ternary condition: (isset($something) or !$something) ? $something : $something_else
.
The following is an example of the difference of using the ??
operator using both null and false:
$false = null;
$var = $false ?? "true";
echo $var . "---<br>";//returns: true---
$false = false;
$var = $false ?? "true";
echo $var . "---<br>"; //returns: ---
By elaborating on the ternary operator however, we can make a false or empty string "" behave as if it were a null without throwing an e_notice:
$false = null;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---
$false = false;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---
$false = "";
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---
$false = true;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: 1---
Personally, I think it would be really nice if a future rev of PHP included another new operator: :?
that replaced the above syntax. ie:
// $var = $false :? "true";
That syntax would evaluate null, false, and "" equally and not throw an E_NOTICE...
Actually there are occasions where (2) is not only preferred but mandatory and I am very surprised, that nobody mentions this here.
Serialization!
If you have a serializable class and you want it to contain a list, then you must declare the field to be of a concrete and serializable type like ArrayList
because the List
interface does not extend java.io.Serializable
Obviously most people do not need serialization and forget about this.
An example:
public class ExampleData implements java.io.Serializable {

I am Fully agree With BugFinder.
In simple Words, just put ip address 192.168.1.56 in your browser running on 192.168.1.2!
if it does not work then there are following possible reasons for that :
Network Connectivity Issue :
Firewall Problem : Your windows firewall setting do not have allowing rule for XAMPP(apache). (Most probable problem)
Apache Configuration problem. : Your apache is configured to listen only local requests.
Port Conflict with other Servers(IIS etc.)
if all above does not work then probably there is some configuration problem on your apache server.try to find it out otherwise just reinstall it and transfer all php files(htdocs) to new installation of XAMPP/WAMP.

If your static variables need to be set at runtime then a static {...}
block is very helpful.
For example, if you need to set the static member to a value which is stored in a config file or database.
Also useful when you want to add values to a static Map
member as you can't add these values in the initial member declaration.
and doesnt give any clues
Yes it does, unfortunately your code is ignoring all of those clues. Take a look at your exception handler:
catch (OleDbException ex)
{
MessageBox.Show(ex.Source);
conn.Close();
}
All you're examining is the source of the exception. Which, in this case, is "Microsoft Access Database Engine". You're not examining the error message itself, or the stack trace, or any inner exception, or anything useful about the exception.
Don't ignore the exception, it contains information about what went wrong and why.
There are various logging tools out there (NLog, log4net, etc.) which can help you log useful information about an exception. Failing that, you should at least capture the exception message, stack trace, and any inner exception(s). Currently you're ignoring the error, which is why you're not able to solve the error.
In your debugger, place a breakpoint inside the catch
block and examine the details of the exception. You'll find it contains a lot of information.
Just put the condition into the lambda itself, e.g.
animalMap.entrySet().stream()
.forEach(
pair -> {
if (pair.getValue() != null) {
myMap.put(pair.getKey(), pair.getValue());
} else {
myList.add(pair.getKey());
}
}
);
Of course, this assumes that both collections (myMap
and myList
) are declared and initialized prior to the above piece of code.
Update: using Map.forEach
makes the code shorter, plus more efficient and readable, as Jorn Vernee kindly suggested:
animalMap.forEach(
(key, value) -> {
if (value != null) {
myMap.put(key, value);
} else {
myList.add(key);
}
}
);
Despite what people are saying here, you don't need JavaScript at all, you don't even need CSS!!
It's actually very doable and simple with HTML only. You can even show a default image if an image doesn't load. Here's how...
This also works on all browsers, even as far back as IE8 (out of 250,000+ visitors to sites I hosted in September 2015, ZERO people used something worse than IE8, meaning this solution works for literally everything).
Step 1: Reference the image as an object instead of an img. When objects fail they don't show broken icons; they just do nothing. Starting with IE8, you can use Object and Img tags interchangeably. You can resize and do all the glorious stuff you can with regular images too. Don't be afraid of the object tag; it's just a tag, nothing big and bulky gets loaded and it doesn't slow down anything. You'll just be using the img tag by another name. A speed test shows they are used identically.
Step 2: (Optional, but awesome) Stick a default image inside that object. If the image you want actually loads in the object, the default image won't show. So for example you could show a list of user avatars, and if someone doesn't have an image on the server yet, it could show the placeholder image... no javascript or CSS required at all, but you get the features of what takes most people JavaScript.
Here is the code...
<object data="avatar.jpg" type="image/jpg">
<img src="default.jpg" />
</object>
... Yes, it's that simple.
If you want to implement default images with CSS, you can make it even simpler in your HTML like this...
<object class="avatar" data="user21.jpg" type="image/jpg"></object>
...and just add the CSS from this answer -> https://stackoverflow.com/a/32928240/3196360
I use following code to get Android id.
String android_id = Secure.getString(this.getContentResolver(),
Secure.ANDROID_ID);
Log.d("Android","Android ID : "+android_id);
I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
We are also looking for some way to convert html files with complex javascript to pdf.
The javasript in our files contains document.write
and DOM manipulation.
We have tried using a combination of HtmlUnit to parse the files and Flying Saucer to render to pdf but the results are not satisfactory enough. It works, but in our case the pdf is not close enough to what the user wants.
If you want to try this out, here is a code snippet to convert a local html file to pdf.
URL url = new File("test.html").toURI().toURL();
WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage(url);
OutputStream os = null;
try{
os = new FileOutputStream("test.pdf");
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(page,url.toString());
renderer.layout();
renderer.createPDF(os);
} finally{
if(os != null) os.close();
}
you can add function and remove all other click by assign them
btn1 = document.querySelector(".btn-1")
btn1.addEventListener("click" , _=>{console.log("hello")})
btn1.addEventListener("click" , _=>{console.log("How Are you ?")})
btn2 = document.querySelector(".btn-2")
btn2.onclick = _=>{console.log("Hello")}
btn2.onclick = _=>{console.log("Bye")}
_x000D_
<button class="btn-1">Hello to Me</button>
<button class="btn-2">Hello to Bye</button>

@Alex Martelli
's answer is great!
But it work only for one element at time (WHERE name = 'Joan'
)
If you take out the WHERE
clause, the query will return all the root rows together...
I changed a little bit for my situation, so it can show the entire tree for a table.
table definition:
CREATE TABLE [dbo].[mar_categories] (
[category] int IDENTITY(1,1) NOT NULL,
[name] varchar(50) NOT NULL,
[level] int NOT NULL,
[action] int NOT NULL,
[parent] int NULL,
CONSTRAINT [XPK_mar_categories] PRIMARY KEY([category])
)
(level
is literally the level of a category 0: root, 1: first level after root, ...)
and the query:
WITH n(category, name, level, parent, concatenador) AS
(
SELECT category, name, level, parent, '('+CONVERT(VARCHAR (MAX), category)+' - '+CONVERT(VARCHAR (MAX), level)+')' as concatenador
FROM mar_categories
WHERE parent is null
UNION ALL
SELECT m.category, m.name, m.level, m.parent, n.concatenador+' * ('+CONVERT (VARCHAR (MAX), case when ISNULL(m.parent, 0) = 0 then 0 else m.category END)+' - '+CONVERT(VARCHAR (MAX), m.level)+')' as concatenador
FROM mar_categories as m, n
WHERE n.category = m.parent
)
SELECT distinct * FROM n ORDER BY concatenador asc
(You don't need to concatenate the level
field, I did just to make more readable)
the answer for this query should be something like:
I hope it helps someone!
now, I'm wondering how to do this on MySQL... ^^
This is because you are adding your <tbody>
tag before <td>
in table you cannot print any data without <td>
.
So for that you have to make a <div>
say #header
with position: fixed;
header
{
position: fixed;
}
make another <div>
which will act as <tbody>
tbody
{
overflow:scroll;
}
Now your header is fixed and the body will scroll. And the header will remain there.
You can use this function in your application to add keys to indexed array.
public static function convertIndexedArrayToAssociative($indexedArr, $keys)
{
$resArr = array();
foreach ($indexedArr as $item)
{
$tmpArr = array();
foreach ($item as $key=>$value)
{
$tmpArr[$keys[$key]] = $value;
}
$resArr[] = $tmpArr;
}
return $resArr;
}
I think using react-native-responsive-dimensions
might help you a little better on your case.
You can still get:
device-width by using and responsiveScreenWidth(100)
and
device-height by using and responsiveScreenHeight(100)
You also can more easily arrange the locations of your absolute components by setting margins and position values with proportioning it over 100% of the width and height
Join on one-to-many relation in JPQL looks as follows:
select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName
When several properties are specified in select
clause, result is returned as Object[]
:
Object[] temp = (Object[]) em.createNamedQuery("...")
.setParameter("groupName", groupName)
.getSingleResult();
String fname = (String) temp[0];
String lname = (String) temp[1];
By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table
to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:
@Entity @Table(name = "Users")
public class User implements Serializable { ... }
I have just had an exciting three hours battling with this. I have just upgraded a project to 4.2 and for some reason it just wouldn't work.
I eventually removed the Entitlements.plist file and then created a new one.
File > New File > Code Signing > Entitlement
Name the file Entitlements.plist
Make sure it's in the Resources group in xCode.
It didn't put in the get-task-allow BOOL type in the Entitlements.plist file. I added it, checked it, saved it, unchecked it, saved it. This made me feel better.
I then removed the Adhoc and Release profiles I had created. Re-downloaded them from the Provisioning Portal and droped them back into the xCode organizer.
I then went into Build Settings and made sure the correct profiles were assigned to the Debug and Release profiles.
I then changed the to Release / Device. Hit the build button and it worked.
I have no idea why.
Flushing the output buffers:
printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is
or
fprintf(fd, "Buffered, will be flushed");
fflush(fd); //Prints to a file
Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf()
it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf
something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.
Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf()
, so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.
I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf()
is an expensive operation (which is why it doesn't by default flush the buffer).
As far as flushing the input buffer (stdin
), you should not do that. Flushing stdin
is undefined behavior according to the C11 standard §7.21.5.2 part 2:
If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.
On some systems, Linux being one as you can see in the man page for fflush()
, there's a defined behavior but it's system dependent so your code will not be portable.
Now if you're worried about garbage "stuck" in the input buffer you can use fpurge()
on that.
See here for more on fflush()
and fpurge()

document.addEventListener('touchstart', function(e) {e.preventDefault()}, false);
document.addEventListener('touchmove', function(e) {e.preventDefault()}, false);
This should prevent scrolling, but it will also break other touch events unless you define a custom way to handle them.
If the bandwidth is far higher than the bitrate, I would recommend TCP for unicast live video streaming.
Case 1: Consecutive packets are lost for a duration of several seconds. => live video will stop on the client side whatever the transport layer is (TCP or UDP). When the network recovers: - if TCP is used, client video player can choose to restart the stream at the first packet lost (timeshift) OR to drop all late packets and to restart the video stream with no timeshift. - if UDP is used, there is no choice on the client side, video restart live without any timeshift. => TCP equal or better.
Case 2: some packets are randomly and often lost on the network. - if TCP is used, these packets will be immediately retransmitted and with a correct jitter buffer, there will be no impact on the video stream quality/latency. - if UDP is used, video quality will be poor. => TCP much better

Why flex vs. display: inline-block
?
Why negative margin?
Either you use SCSS or CSS-in-JS for the edge cases (i.e. first element in column), or you set a default margin and get rid of the outer margin later.

Oracle recommends to add the @Path annotation to all types to be injected when combining JAX-RS with CDI: http://docs.oracle.com/javaee/7/tutorial/jaxrs-advanced004.htm Though this is far from perfect (e.g. you will get warning from Jersey on startup), I decided to take this route, which saves me from maintaining all supported types within a binder.
Example:
@Singleton
@Path("singleton-configuration-service")
public class ConfigurationService {
..
}
@Path("my-path")
class MyProvider {
@Inject ConfigurationService _configuration;
@GET
public Object get() {..}

Refering to ?: Operator (C# Reference)
The conditional operator (?:) returns one of two values depending on the value of a Boolean expression. Following is the syntax for the conditional operator.
Refering to ?? Operator (C# Reference)
The ?? operator is called the null-coalescing operator and is used to define a default value for a nullable value types as well as reference types. It returns the left-hand operand if it is not null; otherwise it returns the right operand.
That means:
[Part 1]
return source ?? String.Empty;
[Part 2] is not applicable ...
Why not just convert both strings to lowercase before you call find()

$domain = $domain | ? {$_ -like 'DC=*'}
$domain = $domain -join "."

Use List.Insert(0, ...)
. But are you sure a LinkedList
isn't a better fit? Each time you insert an item into an array at a position other than the array end, all existing items will have to be copied to make space for the new one.

set(["'"])
Outside of this range the two types are not exchangeable.
>>> '\x80'.encode('string_escape')
'\\x80'
>>> '\x80'.encode('unicode_escape')

In order to convert string to char
String str = "abcd";
char arr [] = new char[len]; // len is the length of the array
arr = str.toCharArray();
int = 4 byte (fixed irrespective size of the architect) NSInteger = depend upon size of the architect(e.g. for 4 byte architect = 4 byte NSInteger size)
one way i have found:
try to insert this field into your generated form code:
<input type='hidden' name='rm' value='2'>
rm means return method;
2 means (post)
Than after user purchases and returns to your site url, then that url gets the POST parameters as well
p.s. if using php, try to insert var_dump($_POST);
in your return url(script),then make a test purchase and when you return back to your site you will see what variables are got on your url.
You need to add logic to assign random values to double[] array using randomFill method.
Change
public static double[] list(){
anArray = new double[10];
return anArray;
}
To
public static double[] list() {
anArray = new double[10];
for(int i=0;i<anArray.length;i++)
{
anArray[i] = randomFill();
}
return anArray;
}
Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console.
public static void main(String args[]) {
list();
print();
}
One result is as follows:
-2.89783865E8
1.605018025E9
-1.55668528E9

For deprecation warnings have a look at how-to-ignore-deprecation-warnings-in-python
Copied here...
From documentation of the warnings
module:
#!/usr/bin/env python -W ignore::DeprecationWarning
If you're on Windows: pass -W ignore::DeprecationWarning
as an argument to Python. Better though to resolve the issue, by casting to int.
(Note that in Python 3.2, deprecation warnings are ignored by default.)
Or:
import warnings
with warnings.catch_warnings():
warnings.filterwarnings("ignore", category=DeprecationWarning)
import md5, sha
yourcode()
Now you still get all the other DeprecationWarning
s, but not the ones caused by:
import md5, sha
Try this,
.truncate {
display:inline-block;
width:180px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
add .truncate
class to your element.
EDIT,
Above solution is not working in all the browsers. you can try following jQuery plugin with cross browser support.
(function ($) {
$.fn.ellipsis = function () {
return this.eachAsync({
delay: 100,
bulk: 0,
loop: function (index) {
var el = $(this);
if (el.data("fullText") !== undefined) {
el.html(el.data("fullText"));
} else {
el.data("fullText", el.html());
}
if (el.css("overflow") == "hidden") {
var text = el.html();
var t = $(this.cloneNode(true))
.hide()
.css('position', 'absolute')
.css('overflow', 'visible')
.width('auto')
.height(el.height())
;
el.after(t);
function width() { return t.width() > el.width(); };
var func = width;
while (text.length > 0 && width()) {
text = text.substr(0, text.length - text.length * 25 / 100);
t.html(text + "...");
}
el.html(t.html());
t.remove();
}
}
});
};
})(jQuery);
how to call,
$("#content_right_head span").ellipsis();
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
Very late but I apologize. Sorry if this is "inefficient" but if you found all the above not working, do try this. Works for above 1.10 also
<script>
$(document).ready(function() {
var position='expanded';
$("#topbar").click(function() {
if (position=='expanded') {
$(this).animate({height:'200px'});
position='collapsed';
} else {
$(this).animate({height:'400px'});
position='expanded';
}
});
});
</script>
This is how Adding new column to Table
ALTER TABLE [tableName]
ADD ColumnName Datatype
E.g
ALTER TABLE [Emp]
ADD Sr_No Int
And If you want to make it auto incremented
ALTER TABLE [Emp]
ADD Sr_No Int IDENTITY(1,1) NOT NULL
Error 493: The column 'i' that was returned from the nodes() method cannot be
used directly. It can only be used with one of the four XML data type
methods, exist(), nodes(), query(), and value(), or in IS NULL and IS NOT
NULL checks.
The above errorr was fixed in SQL Server 2014 by using following snippet
Declare @Ids varchar(50)
Set @Ids = '1,2,3,5,4,6,7,98,234'
DECLARE @XML XML
SET @XML = CAST('<i>' + REPLACE(@Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT SomeTable.*
FROM
SomeTable
cross apply @XML.nodes('i') x(i)
where SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')
I use and like Rapid PHP.
This example selects a new Range
of Cells
defined by the current cell to a cell 5 to the right.
Note that .Offset
takes arguments of Offset(row, columns)
and can be quite useful.
Sub testForStackOverflow()
Range(ActiveCell, ActiveCell.Offset(0, 5)).Copy
End Sub
Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.
Writing that much data to a file is going to take a while.
You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).
You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?
You should also write a function to do the calculation; you could use an inline
function in C99 or later (or C++). The repetition in the code is excruciating to behold.
You should also use C99 notation for main()
, with the explicit return type (and preferably void
for the argument list when you are not using argc
or argv
):
int main(void)
Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 };
(thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static
in front of the functions, and the main array; file
becomes a local to main
; error check the fopen()
, etc.).
I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.
#include <stdio.h>
#define lambda 2.0
#define g 1.0
#define F0 1.0
#define h 0.1
#define e 0.00001
enum { ROWS = 1000, COLS = 10000 };
static double F[ROWS][COLS];
static void Inicio(double D[ROWS][COLS])
{
for (int i = 399; i < 600; i++) // Magic numbers!!
D[i][0] = F0;
}
enum { R = ROWS - 1 };
static inline int ko(int k, int n)
{
int rv = k + n;
if (rv >= R)
rv -= R;
else if (rv < 0)
rv += R;
return(rv);
}
static inline void calculate_value(int i, int k, double A[ROWS][COLS])
{
int ks2 = ko(k, -2);
int ks1 = ko(k, -1);
int kp1 = ko(k, +1);
int kp2 = ko(k, +2);
A[k][i] = A[k][i-1]
+ e/(h*h*h*h) * g*g * (A[kp2][i-1] - 4.0*A[kp1][i-1] + 6.0*A[k][i-1] - 4.0*A[ks1][i-1] + A[ks2][i-1])
+ 2.0*g*e/(h*h) * (A[kp1][i-1] - 2*A[k][i-1] + A[ks1][i-1])

}
static void Iteration(double A[ROWS][COLS])
{
for (int i = 1; i < COLS; i++)
{
for (int k = 0; k < R; k++)
calculate_value(i, k, A);
A[999][i] = A[0][i];
}
}
int main(void)
{
FILE *file = fopen("P2.txt","wt");
if (file == 0)
return(1);
Inicio(F);
Iteration(F);
for (int i = 0; i < COLS; i++)
{
for (int j = 0; j < ROWS; j++)
{
fprintf(file,"%lf \t %.4f \t %lf\n", 1.0*j/10.0, 1.0*i, F[j][i]);
}
}
fclose(file);
return(0);
}
This program writes to P2.txt
instead of P1.txt
. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for
loop became:
for (int i = COLS - 1; i < COLS; i++)
the timings were vastly reduced and very much more consistent:

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.
For everyone who is stuck with .NET 2.0, like me, try the following way (applicable to the example in the OP):
ConfigItemList.ConvertAll<string>(delegate (ConfigItemType ci)
{
return ci.Name;
}).ToArray();
where ConfigItemList is your list variable.
I like a more general functional approach:
/**
* converts a trig function taking radians to degrees
* @param {function} trigFunc - eg. Math.cos, Math.sin, etc.
* @param {number} angle - in degrees
* @returns {number}
*/
const dTrig = (trigFunc, angle) => trigFunc(angle * Math.PI / 180);
or,
function dTrig(trigFunc, angle) {
return trigFunc(angle * Math.PI / 180);
}
which can be used with any radian-taking function:
dTrig(Math.sin, 90);
// -> 1
dTrig(Math.tan, 180);
// -> 0
Hope this helps!
To install pip, securely download get-pip.py.
Then run the following:

When the user session times out, I send back an HTTP 204 status code. Note that the HTTP 204 status contains no content. On the client-side I do this:
xhr.send(null);
if (xhr.status == 204)
Reload();
else
dropdown.innerHTML = xhr.responseText;
Here is the Reload() function:
function Reload() {
var oForm = document.createElement("form");
document.body.appendChild(oForm);
oForm.submit();
}
print reduce(lambda x, y: x + y, l)/(len(l)*1.0)
or like posted previously
sum(l)/(len(l)*1.0)
The 1.0 is to make sure you get a floating point division
Maybe I'm not understanding the question but here is my simple solution that works -
# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)
# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty
I agree that labels are not automatically updated but can easily be updated with the
<label name>.config(text="<new text>" + str(<variable name>))
That just needs to be included in your code after the variable is updated.
If attribute routing is being used, you can use the [FromUri] and [FromBody] attributes.
Example:
[HttpPost()]
[Route("api/products/{id:int}")]
public HttpResponseMessage AddProduct([FromUri()] int id, [FromBody()] Product product)
{
// Add product
}
It's enabled by default. Probably you just tried on an expression that failed to autocomplete.
In case you deactivated it somehow... you can enable it in the Visual Studio settings. Just browse to the Editor settings, then to the subgroup C/C++ and activate it again... should read something like "List members automatically" or "Auto list members" (sorry, I have the german Visual Studio).
Upon typing something like std::cout. a dropwdownlist with possible completitions should pop up.
Go to Control Panel -> Programs -> Programs and features
Go to Windows Features and disable Internet Explorer 11
Then click on Display installed updates
Search for Internet explorer
Right-click on Internet Explorer 11 -> Uninstall
Do the same with Internet Explorer 10
I think it will be okay.
The os.makedirs
function does this. Try the following:
import os
import errno
filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
try:
os.makedirs(os.path.dirname(filename))
except OSError as exc: # Guard against race condition
if exc.errno != errno.EEXIST:
raise
with open(filename, "w") as f:
f.write("FOOBAR")
The reason to add the try-except
block is to handle the case when the directory was created between the os.path.exists
and the os.makedirs
calls, so that to protect us from race conditions.
In Python 3.2+, there is a more elegant way that avoids the race condition above:
import os
filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
f.write("FOOBAR")
if(c is TFrom)
{
// Do Stuff
}
or if you plan on using c
as a TForm
, use the following example:
var tForm = c as TForm;
if(tForm != null)
{
// c is of type TForm
}
The second example only needs to check to see if c
is of type TForm
once. Whereis if you check if see if c
is of type TForm
then cast it, the CLR undergoes an extra check.
Here is a reference.
Edit: Stolen from Jon Skeet
If you want to make sure c
is of TForm
and not any class inheriting from TForm
, then use
if(c.GetType() == typeof(TForm))
{
// Do stuff cause c is of type TForm and nothing else
}
You can use a css selector combination a well
driver.find_element_by_css_selector("#fruits01 [value='1']").click()
Change the 1 in the attribute = value css selector to the value corresponding with the desired fruit.
Check out James Padolsey's animateToSelector
Intro: This jQuery plugin will allow you to animate any element to styles specified in your stylesheet. All you have to do is pass a selector and the plugin will look for that selector in your StyleSheet and will then apply it as an animation.
We use Log4Net at work as the logging provider, with a singleton wrapper for the log instance (although the singleton is under review, questioning whether they are a good idea or not).
We chose it for the following reasons:
I should mention, this is speaking from an ASP.NET development point of view
I can see some merits in using the Trace that is in the .NET framework but I'm not entirely sold on it, mainly because the components I work with don't really do any Trace calls. The only thing that I frequently use that does is System.Net.Mail
from what I can tell.
So we have a library which wraps log4net and within our code we just need stuff like this:
Logger.Instance.Warn("Something to warn about");
Logger.Instance.Fatal("Something went bad!", new Exception());
try {
var i = int.Parse("Hello World");
} catch(FormatException, ex) {
Logger.Instance.Error(ex);
}
Within the methods we do a check to see if the logging level is enabled, so you don't have redundant calls to the log4net API (so if Debug isn't enabled, the debug statements are ignored), but when I get some time I'll be updating it to expose those so that you can do the checks yourself. This will prevent evaluations being undertaken when they shouldn't, eg:
Logger.Instance.Debug(string.Format("Something to debug at {0}", DateTime.Now);
This will become:
if(Logger.DebugEnabled) Logger.Instance.Debug(string.Format("Something to debug at {0}", DateTime.Now);
(Save a bit of execusion time)
By default we log at two locations:
Files are done as rolling of each day or 10mb (IIRC). We don't use the EventLog as it can require higher security than we often want to give a site.
I find Notepad works just fine for reading logs.
Use the zipgroupfileset tag (uses same attributes as a fileset tag); it will unzip all files in the directory and add to your new archive file. More information: http://ant.apache.org/manual/Tasks/zip.html
This is a very useful way to get around the jar-in-a-jar problem -- I know because I have googled this exact StackOverflow question while trying to figure out what to do. If you want to package a jar or a folder of jars into your one built jar with Ant, then forget about all this classpath or third-party plugin stuff, all you gotta do is this (in Ant):
<jar destfile="your.jar" basedir="java/dir">
...
<zipgroupfileset dir="dir/of/jars" />
</jar>
If the script only defines the functions and does nothing else, you can first execute the script within the context of the current shell using the source
or .
command and then simply call the function. See help source
for more information.
You need to run the clone command on what you are calling the server. But I bet you are not running an ssh server on your local client so that won't work anyway. Suggest you follow this approach (check the manual 'cause I'm doing this from memory)
git init --bare
git remote add origin ssh://user@server:/GitRepos/myproject.git
followed by git push origin master
A predicate is a function that returns a true/false (i.e. boolean) value, as opposed to a proposition which is a true/false (i.e. boolean) value. In Java, one cannot have standalone functions, and so one creates a predicate by creating an interface for an object that represents a predicate and then one provides a class that implements that interface. An example of an interface for a predicate might be:
public interface Predicate<ARGTYPE>
{
public boolean evaluate(ARGTYPE arg);
}
And then you might have an implementation such as:
public class Tautology<E> implements Predicate<E>
{
public boolean evaluate(E arg){
return true;
}
}
To get a better conceptual understanding, you might want to read about first-order logic.
Edit
There is a standard Predicate interface (java.util.function.Predicate) defined in the Java API as of Java 8. Prior to Java 8, you may find it convenient to reuse the com.google.common.base.Predicate interface from Guava.
Also, note that as of Java 8, it is much simpler to write predicates by using lambdas. For example, in Java 8 and higher, one can pass p -> true
to a function instead of defining a named Tautology subclass like the above.
I know this is old and that this is a little off topic, but supposing you wanted to uncheck only specific radio buttons in a collection:
$("#go").click(function(){_x000D_
$("input[name='correctAnswer']").each(function(){_x000D_
if($(this).val() !== "1"){_x000D_
$(this).prop("checked",false);_x000D_
}_x000D_
});_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<input id="radio1" type="radio" name="correctAnswer" value="1">1</input>_x000D_
<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>_x000D_
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>_x000D_
<input id="radio4" type="radio" name="correctAnswer" value="4">4</input>_x000D_
<input type="button" id="go" value="go">
_x000D_
And if you are dealing with a radiobutton list, you can use the :checked selector to get just the one you want.
$("#go").click(function(){
$("input[name='correctAnswer']:checked").prop("checked",false);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input id="radio1" type="radio" name="correctAnswer" value="1">1</input>
<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>
<input id="radio4" type="radio" name="correctAnswer" value="4">4</input>
<input type="button" id="go" value="go">
Here's my automatic solution...
This will follow your javac
executable's symlink (setup by yum
and/or alternatives --config java
) backwards to find the JAVA_HOME
. (Toss this in your in your /etc/profile
):
export JAVA_HOME=$(readlink -f /usr/bin/javac | sed 's:/bin/javac$::')
If you wanted a stable path (refreshed on boot) launch something like this:
export JAVA_HOME=$(readlink -f /usr/bin/javac | sed 's:/bin/javac$::')
ln -sfn "${JAVA_HOME}" /usr/lib/jvm/jdk-current
I'm kinda shocked the latter still isn't baked into alternatives
.
There is a computer vision package called HALCON from MVTec whose demos could give you good algorithm ideas. There is plenty of examples similar to your problem that you could run in demo mode and then look at the operators in the code and see how to implement them from existing OpenCV operators.
I have used this package to quickly prototype complex algorithms for problems like this and then find how to implement them using existing OpenCV features. In particular for your case you could try to implement in OpenCV the functionality embedded in the operator find_scaled_shape_model. Some operators point to the scientific paper regarding algorithm implementation which can help to find out how to do something similar in OpenCV. Hope this helps...
As per one of the recent comments to your original question
$(function() {
$(window).resize(adjust_photo_size);
adjust_photo_size();
function adjust_photo_size() {
if (!$("#photo").get(0).complete) {
$("#photo").load(function() {
adjust_photo_size();
});
} else {
...
}
});
Warning This answer could cause a serious loop in ie8 and lower, because img.complete is not always properly set by the browser. If you must support ie8, use a flag to remember the image is loaded.
This piece of code:
for s in ("fukushima", "123 is a number", ""):
print s.ljust(20), s[0].isdigit() if s else False
prints out the following:
fukushima False
123 is a number True
False
Here is my solution, based on previous answers by Paul Grimshaw and Anthony VO. I've submitted the code in a C# project on Github.
My main contribution is to eliminate explicitly creating and manipulating a StringBuilder
and instead working only with IEnumerable
. This avoids the allocation of a big buffer in memory.
public static class Util
{
public static string EscapeQuotes(this string self) {
return self?.Replace("\"", "\"\"") ?? "";
}
public static string Surround(this string self, string before, string after) {
return $"{before}{self}{after}";
}
public static string Quoted(this string self, string quotes = "\"") {
return self.Surround(quotes, quotes);
}
public static string QuotedCSVFieldIfNecessary(this string self) {
return (self == null) ? "" : self.Contains('"') ? self.Quoted() : self;
}
public static string ToCsvField(this string self) {
return self.EscapeQuotes().QuotedCSVFieldIfNecessary();
}
public static string ToCsvRow(this IEnumerable<string> self){
return string.Join(",", self.Select(ToCsvField));
}
public static IEnumerable<string> ToCsvRows(this DataTable self) {
yield return self.Columns.OfType<object>().Select(c => c.ToString()).ToCsvRow();
foreach (var dr in self.Rows.OfType<DataRow>())
yield return dr.ItemArray.Select(item => item.ToString()).ToCsvRow();
}
public static void ToCsvFile(this DataTable self, string path) {
File.WriteAllLines(path, self.ToCsvRows());
}
}
This approach combines nicely with converting IEnumerable
to DataTable as asked here.
First of let's your image name is myimage. So what you have to do is that go to Drawable and save the image name myimage.
Now assume you know only image name and you need to access it. Use below snippet to access it,
what you did is correct , ensure you saved image name you are going to use inside coding.
public static int getResourceId(Context context, String name, String resourceType) {
return context.getResources().getIdentifier(toResourceString(name), resourceType, context.getPackageName());
}
private static String toResourceString(String name) {
return name.replace("(", "")
.replace(")", "")
.replace(" ", "_")
.replace("-", "_")
.replace("'", "")
.replace("&", "")
.toLowerCase();
}
In addition to it you should ensure that there is no empty spaces and case sensitives
I know its been a while since the original post but I like using CTE's and this worked for me:
WITH cte_table_a
AS
(
SELECT [id] [id]
, MAX([value]) [value]
FROM table_a
GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN cte_table_a
ON table_b.id = cte_table_a.id
If you're using Spring Boot 1.4.0 or later as the basis of your annotation-driven, Spring doesn't provides a single auto-configured RestTemplate bean. From their documentation:
https://docs.spring.io/spring-boot/docs/1.4.0.RELEASE/reference/html/boot-features-restclient.html
If you need to call remote REST services from your application, you can use Spring Framework’s RestTemplate class. Since RestTemplate instances often need to be customized before being used, Spring Boot does not provide any single auto-configured RestTemplate bean. It does, however, auto-configure a RestTemplateBuilder which can be used to create RestTemplate instances when needed. The auto-configured RestTemplateBuilder will ensure that sensible HttpMessageConverters are applied to RestTemplate instances.
you can use just javascript for it
var total =10.8
(total).toFixed(2); 10.80
alert(total.toFixed(2)));
From python3 onwards you can use
a == []
to check if the list is empty
EDIT : This works with python2.7 too..
I am not sure why there are so many complicated answers. It's pretty clear and straightforward
<execute-test-successful-condition> if <test> else <execute-test-fail-condition>
with your code-snippet it would become,
count = 0 if count == N else N + 1
p
is the conversion specifier to print pointers. Use this.
int a = 42;
printf("%p\n", (void *) &a);
Remember that omitting the cast is undefined behavior and that printing with p
conversion specifier is done in an implementation-defined manner.
This blog post discusses the best answers to this question.
As a short summary, if you can install CPAN modules then the most readable solutions are:
any(@ingredients) eq 'flour';
or
@ingredients->contains('flour');
However, a more common idiom is:
any { $_ eq 'flour' } @ingredients
But please don't use the first()
function! It doesn't express the intent of your code at all. Don't use the ~~
"Smart match" operator: it is broken. And don't use grep()
nor the solution with a hash: they iterate through the whole list.
any()
will stop as soon as it finds your value.
Check out the blog post for more details.
You are getting this error because you are using the resultSet before the resultSet.next() method.
To get the count the just use this:
while (rs.next ()) `{ count = rs.getInt (1); }
You will get your result.
npm config edit
Opens the config file in an editor. Use the --global flag to edit the global config. now you can delete what ever the registry's you don't want and save file.
npm config list will display the list of available now.

If Object(Model Class/POJO) contains the date in String datatype.
private void sortArray(ArrayList<myObject> arraylist) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"); //your own date format
if (reports != null) {
Collections.sort(arraylist, new Comparator<myObject>() {
@Override
public int compare(myObject o1, myObject o2) {
try {
return simpleDateFormat.parse(o2.getCreated_at()).compareTo(simpleDateFormat.parse(o1.getCreated_at()));
} catch (ParseException e) {
e.printStackTrace();
return 0;
}
}
});
}
If Object(Model Class/POJO) contains date in Date datatype
private void sortArray(ArrayList<myObject> arrayList) {
if (arrayList != null) {
Collections.sort(arrayList, new Comparator<myObject>() {
@Override
public int compare(myObject o1, myObject o2) {
return o2.getCreated_at().compareTo(o1.getCreated_at()); }
});
} }
The above code is for sorting the array in descending order of date, swap o1 and o2 for ascending order.
This worked for me Android Studio 4.0.1:
Close Android Studio.
Navigate to C:\Users[Username].AndroidStudio4.0\config\options
Locate recentProjects.xml and open it.
Scroll down the page you will notice: <option name="lastProjectLocation" value="$USER_HOME$/AndroidStudioProjects" />
Change $USER_HOME$/AndroidStudioProjects to your desired location: /home/USER/AndroidStudioProjects/
Reopen Android studio.
The problem here is in your interpretation of the article you link.
This article is about somebody that is having problems correctly defining the bool relationship operators.
The operator:
These operators should return a bool as they are comparing two objects of the same type. It is usually easiest to define these operators as part of the class. This is because a class is automatically a friend of itself so objects of type Paragraph can examine each other (even each others private members).
There is an argument for making these free standing functions as this lets auto conversion convert both sides if they are not the same type, while member functions only allow the rhs to be auto converted. I find this a paper man argument as you don't really want auto conversion happening in the first place (usually). But if this is something you want (I don't recommend it) then making the comparators free standing can be advantageous.
The stream operators:
When you use these as stream operators (rather than binary shift) the first parameter is a stream. Since you do not have access to the stream object (its not yours to modify) these can not be member operators they have to be external to the class. Thus they must either be friends of the class or have access to a public method that will do the streaming for you.
It is also traditional for these objects to return a reference to a stream object so you can chain stream operations together.
#include <iostream>
class Paragraph
{
public:
explicit Paragraph(std::string const& init)
:m_para(init)
{}
std::string const& to_str() const
{
return m_para;
}
bool operator==(Paragraph const& rhs) const
{
return m_para == rhs.m_para;
}
bool operator!=(Paragraph const& rhs) const
{
// Define != operator in terms of the == operator
return !(this->operator==(rhs));
}
bool operator<(Paragraph const& rhs) const
{
return m_para < rhs.m_para;
}
private:
friend std::ostream & operator<<(std::ostream &os, const Paragraph& p);
std::string m_para;
};
std::ostream & operator<<(std::ostream &os, const Paragraph& p)
{
return os << p.to_str();
}
int main()
{
Paragraph p("Plop");
Paragraph q(p);
std::cout << p << std::endl << (p == q) << std::endl;
}
It sounds like you are depending on some feedback to determine what is getting stuck on the receiving end. You should be checking the outbound mail yourself for obvious "spaminess".
Buy any decent spam control system, and send your outbound mail through it. If you send any decent volume of mail, you should be doing this anyhow, because of the risk of sending outbound viruses, especially if you have desktop windows users.
Proofpoint had spam + anti-virus + some reputation services in a single deployment, for example. (I used to work there, so I happen to know this off the top of my head. I'm sure other vendors in this space have similar features.) But you get the idea. If you send your mail through a basic commerical spam control setup, and it doesn't pass, it shouldn't be going out of your network.
Also, there are some companies that can assist you with increasing delivery rates of non-spam, outbound email, like Habeas.

Use the @Input() decorator in your child component to allow the parent to bind to this input.
In the child component you declare it as is :
@Input() myInputName: myType
To bind a property from parent to a child you must add in you template the binding brackets and the name of your input between them.
Example :
<my-child-component [myChildInputName]="myParentVar"></my-child-component>
But beware, objects are passed as a reference, so if the object is updated in the child the parent's var will be too updated. This might lead to some unwanted behaviour sometime. With primary types the value is copied.
To go further read this :
Docs : https://angular.io/docs/ts/latest/cookbook/component-communication.html
To simplify:
First Initialize this command: (e.g. after InitalizeComponent()
)
yourComboBox.DataSource = Enum.GetValues(typeof(YourEnum));
To retrieve selected item on combobox:
YourEnum enum = (YourEnum) yourComboBox.SelectedItem;
If you want to set value for the combobox:
yourComboBox.SelectedItem = YourEnem.Foo;
I would like to clarify a few things due to seemingly conflicting responses (mostly surrounding IEnumerable).
(1) IQueryable
extends the IEnumerable
interface. (You can send an IQueryable
to something which expects IEnumerable
without error.)
(2) Both IQueryable
and IEnumerable
LINQ attempt lazy loading when iterating over the result set. (Note that implementation can be seen in interface extension methods for each type.)
In other words, IEnumerables
are not exclusively "in-memory". IQueryables
are not always executed on the database. IEnumerable
must load things into memory (once retrieved, possibly lazily) because it has no abstract data provider. IQueryables
rely on an abstract provider (like LINQ-to-SQL), although this could also be the .NET in-memory provider.
Sample use case
(a) Retrieve list of records as IQueryable
from EF context. (No records are in-memory.)
(b) Pass the IQueryable
to a view whose model is IEnumerable
. (Valid. IQueryable
extends IEnumerable
.)
(c) Iterate over and access the data set's records, child entities and properties from the view. (May cause exceptions!)
Possible Issues
(1) The IEnumerable
attempts lazy loading and your data context is expired. Exception thrown because provider is no longer available.
(2) Entity Framework entity proxies are enabled (the default), and you attempt to access a related (virtual) object with an expired data context. Same as (1).
(3) Multiple Active Result Sets (MARS). If you are iterating over the IEnumerable
in a foreach( var record in resultSet )
block and simultaneously attempt to access record.childEntity.childProperty
, you may end up with MARS due to lazy loading of both the data set and the relational entity. This will cause an exception if it is not enabled in your connection string.
Solution
Execute the query and store results by invoking resultList = resultSet.ToList()
This seems to be the most straightforward way of ensuring your entities are in-memory.
In cases where the you are accessing related entities, you may still require a data context. Either that, or you can disable entity proxies and explicitly Include
related entities from your DbSet
.

I want to introduce an IniParser library I've created completely in c#, so it contains no dependencies in any OS, which makes it Mono compatible. Open Source with MIT license -so it can be used in any code.
You can check out the source in GitHub, and it is also available as a NuGet package
It's heavily configurable, and really simple to use.
Sorry for the shameless plug but I hope it can be of help of anyone revisiting this answer.
The changelog is sloppily worded. from __future__ import absolute_import
does not care about whether something is part of the standard library, and import string
will not always give you the standard-library module with absolute imports on.
from __future__ import absolute_import
means that if you import string
, Python will always look for a top-level string
module, rather than current_package.string
. However, it does not affect the logic Python uses to decide what file is the string
module. When you do
python pkg/script.py
pkg/script.py
doesn't look like part of a package to Python. Following the normal procedures, the pkg
directory is added to the path, and all .py
files in the pkg
directory look like top-level modules. import string
finds pkg/string.py
not because it's doing a relative import, but because pkg/string.py
appears to be the top-level module string
. The fact that this isn't the standard-library string
module doesn't come up.
To run the file as part of the pkg
package, you could do
python -m pkg.script
In this case, the pkg
directory will not be added to the path. However, the current directory will be added to the path.
You can also add some boilerplate to pkg/script.py
to make Python treat it as part of the pkg
package even when run as a file:
if __name__ == '__main__' and __package__ is None:
__package__ = 'pkg'
However, this won't affect sys.path
. You'll need some additional handling to remove the pkg
directory from the path, and if pkg
's parent directory isn't on the path, you'll need to stick that on the path too.
A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.
Your code, for reference:
function funcName() {
alert("test");
}
var func = funcName();
var run = setInterval("func",10000)
Let's break this up into chunks. Your function funcName
is fine. Note that when you call funcName
(in other words, you run it) you will be alerting "test"
. But notice that funcName()
-- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined
.
When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName()
. But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.
So, when you say:
var func = funcName();
You are actually declaring a variable func
that has a value of funcName()
. But notice the parentheses. funcName()
is actually the return value of funcName
. As I said above, since funcName
doesn't actually return any value, it defaults to undefined
. So, in other words, your variable func
actually will have the value undefined
.
Then you have this line:
var run = setInterval("func",10000)
The function setInterval
takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.
However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval
on that string instead. So, in other words, your setInterval is running the following JavaScript code:
func
// 10 seconds later....
func
// and so on
However, func
is just a variable (with the value undefined
, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func
and returns undefined
. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.
The solution is to give setInterval
a function to run instead of a string. So, in this case:
var run = setInterval(funcName, 10000);
Notice that I didn't give it func
. This is because func
is not a function in your code; it's the value undefined
, because you assigned it funcName()
. Like I said above, funcName()
will call the function funcName
and return the return value of the function. Since funcName
doesn't return anything, this defaults to undefined
. I know I've said that several times now, but it really is a very important concept: when you see funcName()
, you should think "the return value of funcName
". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName
.
So, another solution for your code would be:
var func = funcName;
var run = setInterval(func, 10000);
However, that's a bit redundant: why use func
instead of funcName
?
Or you can stay as true as possible to the original code by modifying two bits:
var func = funcName;
var run = setInterval("func()", 10000);
In this case, the JS engine will evaluate func()
every ten seconds. In other words, it will alert "test"
every ten seconds. However, as the famous phrase goes, eval
is evil, so you should try to avoid it whenever possible.
Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.
setInterval(function () {
alert("test");
}, 10000);
In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.
What worked for me was:
npm update prettier
npm run lint -- --fix
It was not necessary to change .eslintrc and .prettierrc files!
for python 3 it worked for what @HYRY posted. I needed it for a returned data in a dbus.array. This is the only way it worked
s = "ABCD"
from array import array
a = array("B", s)
This might be an old qustion, but just to keep things updated, there is a forEach method in javascript that works with NodeJS. Here's the link from the docs. And an example:
count = countElements.length;
if (count > 0) {
countElements.forEach(function(countElement){
console.log(countElement);
});
}
A functor is pretty much just a class which defines the operator(). That lets you create objects which "look like" a function:
// this is a functor
struct add_x {
add_x(int val) : x(val) {} // Constructor
int operator()(int y) const { return x + y; }
private:
int x;
};
// Now you can use it like this:
add_x add42(42); // create an instance of the functor class
int i = add42(8); // and "call" it
assert(i == 50); // and it added 42 to its argument
std::vector<int> in; // assume this contains a bunch of values)
std::vector<int> out(in.size());
// Pass a functor to std::transform, which calls the functor on every element
// in the input sequence, and stores the result to the output sequence
std::transform(in.begin(), in.end(), out.begin(), add_x(1));
assert(out[i] == in[i] + 1); // for all i
There are a couple of nice things about functors. One is that unlike regular functions, they can contain state. The above example creates a function which adds 42 to whatever you give it. But that value 42 is not hardcoded, it was specified as a constructor argument when we created our functor instance. I could create another adder, which added 27, just by calling the constructor with a different value. This makes them nicely customizable.
As the last lines show, you often pass functors as arguments to other functions such as std::transform or the other standard library algorithms. You could do the same with a regular function pointer except, as I said above, functors can be "customized" because they contain state, making them more flexible (If I wanted to use a function pointer, I'd have to write a function which added exactly 1 to its argument. The functor is general, and adds whatever you initialized it with), and they are also potentially more efficient. In the above example, the compiler knows exactly which function std::transform
should call. It should call add_x::operator()
. That means it can inline that function call. And that makes it just as efficient as if I had manually called the function on each value of the vector.
If I had passed a function pointer instead, the compiler couldn't immediately see which function it points to, so unless it performs some fairly complex global optimizations, it'd have to dereference the pointer at runtime, and then make the call.
With Mac OS X and the more recent versions of Acrobat Pro, the PDF printer option does not work. What does work is doing basically the same thing in Preview App. Open the multi page file in Preview, select File>Print. In the Print dialog set your sheet size as if you are using a printer. You may want to select "Auto Rotate", "Scale to Fit" and "Print Entire Image". Then in the lower left corner is the drop button "PDF" and in that menu select "Save as PDF". Give it a new file name, click Save and then you can open the resulting file in whatever PDF app you want and the sheet sizes are the same.
I've found that the ''.join(chr(ord(a)^ord(b)) for a,b in zip(s,m)) method is pretty slow. Instead, I've been doing this:
fmt = '%dB' % len(source)
s = struct.unpack(fmt, source)
m = struct.unpack(fmt, xor_data)
final = struct.pack(fmt, *(a ^ b for a, b in izip(s, m)))
Okay, so you want to calculate a^b mod m
. First we'll take a naive approach and then see how we can refine it.
First, reduce a mod m
. That means, find a number a1
so that 0 <= a1 < m
and a = a1 mod m
. Then repeatedly in a loop multiply by a1
and reduce again mod m
. Thus, in pseudocode:
a1 = a reduced mod m
p = 1
for(int i = 1; i <= b; i++) {
p *= a1
p = p reduced mod m
}
By doing this, we avoid numbers larger than m^2
. This is the key. The reason we avoid numbers larger than m^2
is because at every step 0 <= p < m
and 0 <= a1 < m
.
As an example, let's compute 5^55 mod 221
. First, 5
is already reduced mod 221
.
1 * 5 = 5 mod 221
5 * 5 = 25 mod 221
25 * 5 = 125 mod 221
125 * 5 = 183 mod 221
183 * 5 = 31 mod 221
31 * 5 = 155 mod 221
155 * 5 = 112 mod 221
112 * 5 = 118 mod 221
118 * 5 = 148 mod 221
148 * 5 = 77 mod 221
77 * 5 = 164 mod 221
164 * 5 = 157 mod 221
157 * 5 = 122 mod 221
122 * 5 = 168 mod 221
168 * 5 = 177 mod 221
177 * 5 = 1 mod 221
1 * 5 = 5 mod 221
5 * 5 = 25 mod 221
25 * 5 = 125 mod 221
125 * 5 = 183 mod 221
183 * 5 = 31 mod 221
31 * 5 = 155 mod 221
155 * 5 = 112 mod 221
112 * 5 = 118 mod 221
118 * 5 = 148 mod 221
148 * 5 = 77 mod 221
77 * 5 = 164 mod 221
164 * 5 = 157 mod 221
157 * 5 = 122 mod 221
122 * 5 = 168 mod 221
168 * 5 = 177 mod 221
177 * 5 = 1 mod 221
1 * 5 = 5 mod 221
5 * 5 = 25 mod 221
25 * 5 = 125 mod 221
125 * 5 = 183 mod 221
183 * 5 = 31 mod 221
31 * 5 = 155 mod 221
155 * 5 = 112 mod 221
112 * 5 = 118 mod 221
118 * 5 = 148 mod 221
148 * 5 = 77 mod 221
77 * 5 = 164 mod 221
164 * 5 = 157 mod 221
157 * 5 = 122 mod 221
122 * 5 = 168 mod 221
168 * 5 = 177 mod 221
177 * 5 = 1 mod 221
1 * 5 = 5 mod 221
5 * 5 = 25 mod 221
25 * 5 = 125 mod 221
125 * 5 = 183 mod 221
183 * 5 = 31 mod 221
31 * 5 = 155 mod 221
155 * 5 = 112 mod 221
Therefore, 5^55 = 112 mod 221
.
Now, we can improve this by using exponentiation by squaring; this is the famous trick wherein we reduce exponentiation to requiring only log b
multiplications instead of b
. Note that with the algorithm that I described above, the exponentiation by squaring improvement, you end up with the right-to-left binary method.
a1 = a reduced mod m
p = 1
while (b > 0) {
if (b is odd) {
p *= a1
p = p reduced mod m
}
b /= 2
a1 = (a1 * a1) reduced mod m
}
Thus, since 55 = 110111 in binary
1 * (5^1 mod 221) = 5 mod 221
5 * (5^2 mod 221) = 125 mod 221
125 * (5^4 mod 221) = 112 mod 221
112 * (5^16 mod 221) = 112 mod 221
112 * (5^32 mod 221) = 112 mod 221
Therefore the answer is 5^55 = 112 mod 221
. The reason this works is because
55 = 1 + 2 + 4 + 16 + 32
so that
5^55 = 5^(1 + 2 + 4 + 16 + 32) mod 221
= 5^1 * 5^2 * 5^4 * 5^16 * 5^32 mod 221
= 5 * 25 * 183 * 1 * 1 mod 221
= 22875 mod 221
= 112 mod 221
In the step where we calculate 5^1 mod 221
, 5^2 mod 221
, etc. we note that 5^(2^k)
= 5^(2^(k-1)) * 5^(2^(k-1))
because 2^k = 2^(k-1) + 2^(k-1)
so that we can first compute 5^1
and reduce mod 221
, then square this and reduce mod 221
to obtain 5^2 mod 221
, etc.
The above algorithm formalizes this idea.
// Initiate set interval and assign it to intervalListener
var intervalListener = self.setInterval(function () {someProcess()}, 1000);
function someProcess() {
console.log('someProcess() has been called');
// If some condition is true clear the interval
if (stopIntervalIsTrue) {
window.clearInterval(intervalListener);
}
}
If you're using eclipse you can open default.properties
file in your workspace and change the project target to the new sdk (target=android-8
for 2.2). I accidentally selected the 1.5 sdk for my version and didn't catch it until much later, but updating that and restarting eclipse seemed to have done the trick.
I know this is old, but I had trouble with some solutions and pieced this together. I have tested this on Windows (Chrome, Firefox and MSIE) and OS X (Chrome and Safari) and believe this is the simplest solution. It works with these three style of attaching a label.
<label><input type="checkbox" class="c123" id="cb1" name="item1">item1</label>
<input type="checkbox" class="c123" id="cb2" name="item2">item2</input>
<input type="checkbox" class="c123" id="cb3" name="item3"><label for="cb3">item3</label>
Using jQuery:
$(".c123").click(function() {
$cb = $(this);
$lb = $(this).parent();
alert( $cb.attr('id') + ' = ' + $lb.text() );
});

I was just dealing with Windows Communication Foundation [WCF] Named Pipe and I did notice that it does make sense to use Structs in order to ensure that exchange of data is of value type instead of reference type.
ConcurrentHashMap is optimized for concurrent access.
Accesses don't lock the whole map but use a finer grained strategy, which improves scalability. There are also functional enhanvements specifically for concurrent access, e.g. concurrent iterators.
I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install
. When I changed to the directory that had my makefile it worked.
So possibly you aren't in the right directory.
Getting the next 5 days:
var date = new Date(),
d = date.getDate(),
m = date.getMonth(),
y = date.getFullYear();
for(i=0; i < 5; i++){
var curdate = new Date(y, m, d+i)
console.log(curdate)
}
Here's a one line solution without a while loop.
The order is preserved in the resulting list.
The potential downsides are
let re = /\s*([^[:]+):\"([^"]+)"/g
let str = '[description:"aoeu" uuid:"123sth"]'
(str.match(re) || []).map(e => RegExp(re.source, re.flags).exec(e))
[ [ 'description:"aoeu"',
'description',
'aoeu',
index: 0,
input: 'description:"aoeu"',
groups: undefined ],
[ ' uuid:"123sth"',
'uuid',
'123sth',
index: 0,
input: ' uuid:"123sth"',
groups: undefined ] ]
I seem to be a bit late to the party and much more of a beginner than any expertise; BUT this worked for me:
window.onbeforeunload = function() {
return false;
};
I placed this as an inline script immediately after my Head and Meta elements, like this:
<script>
window.onbeforeunload = function() {
return false;
}
</script>
This page seems to me to be highly relevant to the originator's requirement (especially the sections headed window.onunload
and window.onbeforeunload
):

In my case I have a gradle nature project in eclipse, the problem was in a build.gradle
, where this sourceSets
is specified:
sourceSets {
main {
java {
srcDir 'src'
}
}
}
This seems to works well with intelliJ,however seems than eclipse doesn't like nest src
, src/java
, src/resources
. In eclipse I must change it to:
sourceSets {
main {
java {
srcDir 'src/main/java'
}
}
}
Generally, I find RandomUtils (from Apache commons lang) an easier way to generate random numbers than java.util.Random
Try toFixed
instead of toPrecision
.
After having had the same problem, I came to this solutions using tags. The idea behind it is simple: Whenever the spinner is changed programatically, make sure the tag reflects the selected position. In the listener then you check if the selected position equals the tag. If it does, the spinner selection was changed programatically.
Below is my new "spinner proxy" class:
package com.samplepackage;
import com.samplepackage.R;
import android.widget.Spinner;
public class SpinnerFixed {
private Spinner mSpinner;
public SpinnerFixed(View spinner) {
mSpinner = (Spinner)spinner;
mSpinner.setTag(R.id.spinner_pos, -2);
}
public boolean isUiTriggered() {
int tag = ((Integer)mSpinner.getTag(R.id.spinner_pos)).intValue();
int pos = mSpinner.getSelectedItemPosition();
mSpinner.setTag(R.id.spinner_pos, pos);
return (tag != -2 && tag != pos);
}
public void setSelection(int position) {
mSpinner.setTag(R.id.spinner_pos, position);
mSpinner.setSelection(position);
}
public void setSelection(int position, boolean animate) {
mSpinner.setTag(R.id.spinner_pos, position);
mSpinner.setSelection(position, animate);
}
// If you need to proxy more methods, use "Generate Delegate Methods"
// from the context menu in Eclipse.
}
You will also need an XML file with the tag setup in your Values
directory.
I named my file spinner_tag.xml
, but that's up to you.
It looks like this:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<item name="spinner_pos" type="id" />
</resources>
Now replace
Spinner myspinner;
...
myspinner = (Spinner)findViewById(R.id.myspinner);
in your code with
SpinnerFixed myspinner;
...
myspinner = new SpinnerFixed(findViewById(R.id.myspinner));
And make your handler somewhat look like this:
myspinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (myspinner.isUiTriggered()) {
// Code you want to execute only on UI selects of the spinner
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
The function isUiTriggered()
will return true if and only if the spinner has been changed by the user. Note that this function has a side effect - it will set the tag, so a second call in the same listener call will always return false
.
This wrapper will also handle the problem with the listener being called during layout creation.
Have fun, Jens.

This error message happens either because your ProfileDto
class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class)
to make processable by JAXB.
About your comment:
I was under the impression the annotations was only needed when the referenced class was a sub-class.
No, they are also needed when not declared in the JAXB context or, for example, when the only class having a static reference to it has this reference annotated with @XmlTransient
. I maintain a tutorial here.
I dont have a copy of Delphi to hand, but I'm fairly certain if you set the wordwrap property to true and the autosize property to false it should wrap any text you put it at the size you make the label. If you want to line break in a certain place then it might work if you set the above settings and paste from a text editor.
Hope this helps.
RenderParital is Better to use for performance.
{@Html.RenderPartial("_LoadView");}
There is an insightful blog post about it.
See https://anonbadger.wordpress.com/2015/06/16/why-sys-setdefaultencoding-will-break-code/.
I paraphrase its content below.
In python 2 which was not as strongly typed regarding the encoding of strings you could perform operations on differently encoded strings, and succeed. E.g. the following would return True
.
u'Toshio' == 'Toshio'
That would hold for every (normal, unprefixed) string that was encoded in sys.getdefaultencoding()
, which defaulted to ascii
, but not others.
The default encoding was meant to be changed system-wide in site.py
, but not somewhere else. The hacks (also presented here) to set it in user modules were just that: hacks, not the solution.
Python 3 did changed the system encoding to default to utf-8 (when LC_CTYPE is unicode-aware), but the fundamental problem was solved with the requirement to explicitly encode "byte"strings whenever they are used with unicode strings.
The simple answer is: ^[1-9][0-9]*$
Just add onsubmit
event handler for your form:
<form action="insert.php" onsubmit="return myFunction()" method="post">
Remove onclick
from button
and make it input
with type submit
<input type="submit" value="Submit">
And add boolean return statements to your function:
function myFunction() {
var pass1 = document.getElementById("pass1").value;
var pass2 = document.getElementById("pass2").value;
var ok = true;
if (pass1 != pass2) {
//alert("Passwords Do not match");
document.getElementById("pass1").style.borderColor = "#E34234";
document.getElementById("pass2").style.borderColor = "#E34234";
return false;
}
else {
alert("Passwords Match!!!");
}
return ok;
}
In regards to iterative variable names, I like making dynamic variables using Template literals. Every Tom, Dick, and Harry uses the array-style, which is fine. Until you're working with arrays and dynamic variables, oh boy! Eye-bleed overload. Since Template literals have limited support right now, eval()
is even another option.
v0 = "Variable Naught";
v1 = "Variable One";
for(i = 0; i < 2; i++)
{//console.log(i) equivalent is console.log(`${i}`)
dyV = eval(`v${i}`);
console.log(`v${i}`); /* => v0; v1; */
console.log(dyV); /* => Variable Naught; Variable One; */
}
When I was hacking my way through the APIs I made this little looping snippet to see behavior depending on what was done with the Template literals compared to say, Ruby. I liked Ruby's behavior more; needing to use eval()
to get the value is kind of lame when you're used to getting it automatically.
_0 = "My first variable"; //Primitive
_1 = {"key_0":"value_0"}; //Object
_2 = [{"key":"value"}] //Array of Object(s)
for (i = 0; i < 3; i++)
{
console.log(`_${i}`); /* var
* => _0 _1 _2 */
console.log(`"_${i}"`); /* var name in string
* => "_0" "_1" "_2" */
console.log(`_${i}` + `_${i}`); /* concat var with var
* => _0_0 _1_1 _2_2 */
console.log(eval(`_${i}`)); /* eval(var)
* => My first variable
Object {key_0: "value_0"}
[Object] */
}
To do this without relying on any GNUisms such as -i
without a parameter or c
without a linebreak:
sed '/TEXT_TO_BE_REPLACED/c\
This line is removed by the admin.
' infile > tmpfile && mv tmpfile infile
In this (POSIX compliant) form of the command
c\
text
text
can consist of one or multiple lines, and linebreaks that should become part of the replacement have to be escaped:
c\
line1\
line2
s/x/y/
where s/x/y/
is a new sed command after the pattern space has been replaced by the two lines
line1
line2
I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)
For example:
$('.btnName').click(function() {
top.$('#panel').toggle(function() {
$(this).animate({
// style change
}, 500);
},
function() {
$(this).animate({
// style change back
}, 500);
});
This works for me:
$entities = $em->getRepository('MyBundle:MyTable')->findBy(array(),array('name' => 'ASC'));
Keeping the first array empty fetches back all data, it worked in my case.
I think what you want to do is actually pass by reference (pointer) to the function-- create a new environment (which are passed by reference to functions) with the list added to it:
listptr=new.env(parent=globalenv())
listptr$list=mylist
#Then the function is modified as:
lPtrAppend <- function(lstptr, obj) {
lstptr$list[[length(lstptr$list)+1]] <- obj
}
Now you are only modifying the existing list (not creating a new one)
DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.
That is, try adding -lpthread
to your command line.
We should use the transform function from STL algorithm, the last parameter of transform function could be a function object, function pointer or a lambda function that convert item of map to item of vector. This case map have items have type pair that need to convert to item that has int type for vector. Here is my solution that I use lambda function:
#include <algorithm> // for std::transform
#include <iterator> // for back_inserted
// Map of pair <int, string> need to convert to vector of string
std::map<int, std::string> mapExp = { {1, "first"}, {2, "second"}, {3, "third"}, {4,"fourth"} };
// vector of string to store the value type of map
std::vector<std::string> vValue;
// Convert function
std::transform(mapExp.begin(), mapExp.end(), std::back_inserter(vValue),
[](const std::pair<int, string> &mapItem)
{
return mapItem.second;
});

Here you go. I have used this code with UIView, though. You should be able to make those adjustments for scrollview.
func addKeyboardNotifications() {
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillShow(notification:)),
name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillHide(notification:)),
name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
// if using constraints
// bottomViewBottomSpaceConstraint.constant = keyboardSize.height
self.view.frame.origin.y -= keyboardSize.height
UIView.animate(withDuration: duration) {
self.view.layoutIfNeeded()
}
}
}
func keyboardWillHide(notification: NSNotification) {
let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
//if using constraint
// bottomViewBottomSpaceConstraint.constant = 0
self.view.frame.origin.y = 0
UIView.animate(withDuration: duration) {
self.view.layoutIfNeeded()
}
}
Don't forget to remove notifications at right place.
func removeKeyboardNotifications() {
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
From here what I understand DataFrames are:
DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects.
And Series are:
Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.).
Series have a name
attribute which can be accessed like so:
In [27]: s = pd.Series(np.random.randn(5), name='something')
In [28]: s
Out[28]:
0 0.541
1 -1.175
2 0.129
3 0.043
4 -0.429
Name: something, dtype: float64
In [29]: s.name
Out[29]: 'something'
EDIT: Based on OP's comments, I think OP was looking for something like:
>>> df = pd.DataFrame(...)
>>> df.name = 'df' # making a custom attribute that DataFrame doesn't intrinsically have
>>> print(df.name)
'df'
Did you tried to start from right to left by using the rev command ? In this case you just need to print the 2nd column:

Setting the $PYTHONPATH environment variable does not seem to affect the Spyder IDE's iPython terminals on a Mac. However, Spyder's application menu contains a "PYTHONPATH manager." Adding my path here solved my problem. The "PYTHONPATH manager" is also persistent across application restarts.
This is specific to a Mac, because setting the PYTHONPATH environment variable on my Windows PC gives the expected behavior (modules are found) without using the PYTHONPATH manager in Spyder.
Perhaps they would have been satisfied with a knowledge of memalign? And as Jonathan Leffler points out, there are two newer preferable functions to know about.
Oops, florin beat me to it. However, if you read the man page I linked to, you'll most likely understand the example supplied by an earlier poster.
Cardinality of a set is the namber of the elements in set for we have a set a > a,b,c < so ths set contain 3 elements 3 is the cardinality of that set
Take a look at the facilities provided by the time
module
You have several conversion functions there.
Edit: see the datetime
module for more OOP-like solutions. The time
library linked above is kinda imperative.
Will result always be the floor of the division?
No. The result varies, but variation happens only for negative values.
What is the defined behavior?
To make it clear floor rounds towards negative infinity,while integer division rounds towards zero (truncates)
For positive values they are the same
int integerDivisionResultPositive= 125/100;//= 1
double flooringResultPositive= floor(125.0/100.0);//=1.0
For negative value this is different
int integerDivisionResultNegative= -125/100;//=-1
double flooringResultNegative= floor(-125.0/100.0);//=-2.0
This code has helped me to dock some executable in windows form. like NotePad, Excel, word, Acrobat reader n many more...
But it wont work for some applications. As sometimes when you start process of some application.... wait for idle time... and the try to get its mainWindowHandle.... till the time the main window handle becomes null.....
so I have done one trick to solve this
If you get main window handle as null... then search all the runnning processes on sytem and find you process ... then get the main hadle of the process and the set panel as its parent.
ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "xxxxxxxxxxxx.exe";
info.Arguments = "yyyyyyyyyy";
info.UseShellExecute = true;
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Maximized;
info.RedirectStandardInput = false;
info.RedirectStandardOutput = false;
info.RedirectStandardError = false;
System.Diagnostics.Process p = System.Diagnostics.Process.Start(info);
p.WaitForInputIdle();
Thread.Sleep(3000);
Process[] p1 ;
if(p.MainWindowHandle == null)
{
List<String> arrString = new List<String>();
foreach (Process p1 in Process.GetProcesses())
{
// Console.WriteLine(p1.MainWindowHandle);
arrString.Add(Convert.ToString(p1.ProcessName));
}
p1 = Process.GetProcessesByName("xxxxxxxxxxxx");
//p.WaitForInputIdle();
Thread.Sleep(5000);
SetParent(p1[0].MainWindowHandle, this.panel2.Handle);
}
else
{
SetParent(p.MainWindowHandle, this.panel2.Handle);
}
Solved the problem with:
sudo chown -R $USER:$USER /var/www/folder-name
sudo chmod -R 755 /var/www
Grant permissions
I got the same problem and it is not the solution that you told. So I changed the "from datetime import datetime" to "import datetime". After that with the help of "datetime.datetime" I can get the whole modules correctly. I guess this is the correct answer to that question.
