Will changing an events Time-Zone affect other people on shared events?
If I were to normalize an EKEvent 's startDate property using a
NSFormatter or by setting the time zone with
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"hh:mm a"];
[formatter setTimeZone:[NSTimeZone systemTimeZone]];
event.startDate = [formatter dateFromString:[NSString
stringWithFormat:@"%@", [event.startDate]]];
and I later make a change to that event requiring me to call
[self.event.eventStore saveEvent:currentEvent span:EKSpanThisEvent
commit:YES error:nil];
Would it override the time-zone on the server, causing issues for the
person (whom uses GCal) in another state that originally created that
shared calendar event, or is it just a local change?

How to get /, /article to map to same action in PHP Slim
How to get /, /article to map to same action in PHP Slim
I want to map two routes : / and /articles to the same action list_articles.
I tried using this code but it's not working.
$app->get('/:route', function () use($app, $layout) {
echo "test"
})->conditions(array("route" => "(/|articles)"))->name('list_articles');
What am I typing wrong?

Android R file not building when declare-styleable of type enum is added
Android R file not building when declare-styleable of type enum is added
Recently my Android workspace isn't compiling correctly anymore (the R
file isn't created). After trying the usual like cleaning i started
searching deeper. I discovered that when i comment out the items int my

file is build but not when they are present (not commented out). Is there
a recent change or something with the way you have the declare enums or

H1's are floating into post above in Wordpress theme
H1's are floating into post above in Wordpress theme
I just noticed that on the Wordpress theme I created the H1 article titles
are floating up into the subsequent article when you start to shrink the
browser window. I can't seem to find the reason for this. Any insights
would be greatly appreciated.
ul.info li, .excerpt, .post-link {
float: left;
}
The styles above seem to be pushing the title of the article up but if I
remove it then "posted by, written on, date" all turn into a horizontal
list. Which I don't want.
I don't know if they're related by I noticed when I look at single post
pages if I shrink the browser window the content of the article flows off
the screen.
Thanks in advance for you help everyone. Really confused.

When can I get away with using short variable names?
When can I get away with using short variable names?
I often find that people stress using variable names that appropriately
and accurately describe what the variable is trying to convey. This is
also often very hard to do in a word or two. I find it true that though
longer names are typically more accepted, they often lead to code that is
even less readable because of mere clutter. I find that once I understand
what a variable conveys, the name is merely an alias for that
understanding, and that the name itself does not necessarily make a
difference. In that case, I would personally almost always prefer shorter
names to longer ones.
Is it ever appropriate to use short variable names? Is it acceptable to
use names that aren't necessarily understood without looking at the rest
of the algorithm or class, but perhaps which are commented at declaration
of the variable or beginning of the algorithm? Or is it generally always
preferable to have longer names that immediately and definitively convey
meaning?

How to use a subquery inside another subquery with three tables in mysql?
How to use a subquery inside another subquery with three tables in mysql?
I have three tables in my database, see the structure below :

user table contains all user related fields
questions table contains all question related data with the foreign key uid
followers table stores the information of how many times a question followed
What I want my query to return is :
unique uid,
fname
question count for each user
follower count for each user
I have written a query and its working fine and returning the records as I
want but the followers count is always 0. Here is my query :
SELECT
u.uid, u.fname, u.date_joined ,
(SELECT COUNT(*) FROM questions WHERE questions.uid = u.uid) AS
question_count,
(SELECT COUNT(*) FROM followers WHERE followers.qid IN (
SELECT GROUP_CONCAT(qid) FROM questions WHERE questions.uid = u.uid
)
) AS follow_count
FROM epc_user AS u
ORDRE BY follow_count DESC, question_count DESC, date_joined DESC
I tried several different combinations but none of them worked, maybe I am
writing a wrong query or its not possible to use subquery in another
subquery, whatever it may be. I just want to know if its possible or not
and if possible, can any one help me figuring it out.
Any help would be highly appreciated.

Run a PHP script on server start
Run a PHP script on server start
I'm writing a PHP script (OK, it's a daemon worker) that I'd like to run
in the background, and it follows the following pseudo-code:
do {
// stuff
sleep(60*30); // 30 minutes
} while(1);
Now, how can I set this baby up to run automatically in the event that the
server gets restarted. I don't need to worry about state, since everything
is stored in the MySQL DB - and it should just be able to pick up right
where it left off.
I'm using an Ubuntu 12.04 x64 server, on AWS (if that matters).
Thanks!

Using RequireJS for Recursive Map
Using RequireJS for Recursive Map
I'm using requireJS for my web application, and I'm stumped on how to use
requireJS to build a recursive map of the same object. For example, my
object is called 'section', and I want to create a child below each using
the same object:
Section
> Section
> Section
> (etc...)
Here is the contents of section.js:
define(['jquery'], function($) {
children = [];
function init() {
require(['jquery', 'section'], function($, section) {
children.push(section.init(mediator, this));
});
return children;
}
return {
init: init
}
}
This has resulted in a self-referencing mess. I don't know how I can
create a new instance of section for the new, child section.

Verified google places listing not showing up in google search
Verified google places listing not showing up in google search
Even though my Google Places listing has been verified nad my google+ page
is verified and both are connected to my webpage, there is no map or
indication that they are connected when i search for my page.
The company name is Ivanka moda, and when i search for it this is what i
get: Ivanka moda Search
But when i search for my neighbour's bike shop i get this (the highlighted
areas are the ones that i want): Ciklo Centar Search
To make thing even more confusing, when i search on a mobile phone the
oposite happens. The map for Ivanka moda turns up, but for Ciklo Centar it
doesn't.
The question is how to make the map and the link with the pin turn up on a
desktop search too?
Thank you!

301 redirect with ? (question mark) not working in htacces
301 redirect with ? (question mark) not working in htacces
This is probably an easy question, but we can not find why the 301 is not
working. When we have a url with a question mark the 301 redirect in our
.htacces is not working. For example:
/order/order.html?AddID=1078&Rand=666171759380936096
so: Redirect 301 /order/order.html?AddID=1078&Rand=666171759380936096
http://www.domain.nl
In our webmaster tools we have 8000 url's with the same structure
/order/order.html?AddID=.... that say 404 not found. We want to 301
redirect them to the homepage, but we get a 404 not found page instead.
when we use the same redirect with only /order/order.html he is redirected
correct.

Reducing Cassandra heap usage
Reducing Cassandra heap usage
Using Cassandra 1.1.5, have been battling slow write performance, JVM GC
lockups, ... in our logs, we see this rather frequently:
WARN [ScheduledTasks:1] 2013-08-28 09:28:51,983 GCInspector.java (line
145) Heap is 0.8589157615524839 full. You may need to reduce memtable
and/or cache sizes. Cassandra will now flush up to the two largest
memtables to free up memory. Adjust flush_largest_memtables_at threshold
in cassandra.yaml if you don't want Cassandra to do this automatically
The largest memtable in our system (as observed through JConsole) runs up
to about 20,000,000 data size (which I assume is ~20MB, if those are
bytes).
If it matters, this column family has almost 1B rows in it.
flush_largest_memtables_at is set to .75, but it seems we hit that almost
continuously. The pattern for this table is heavy writes, and very little
reads. (essentially a clustered log)
Row cache is disabled, key cache is set to 40MB. We have 8GB of heap
associated to the JVM (24GB of physical).
Heap usage is between 6.5 and 7.5GB, mostly.
Advice on what to look at to reduce heap usage here? Surely it's not a
factor of how much data we have in the cluster, is it? (We have gobs of
disk available across this cluster)

WARN [ScheduledTasks:1] 2013-08-28 09:28:51,983 GCInspector.java (line
145) Heap is 0.8589157615524839 full. You may need to reduce memtable
and/or cache sizes. Cassandra will now flush up to the two largest
memtables to free up memory. Adjust flush_largest_memtables_at threshold
in cassandra.yaml if you don't want Cassandra to do this automatically
The largest memtable in our system (as observed through JConsole) runs up
to about 20,000,000 data size (which I assume is ~20MB, if those are
bytes).
If it matters, this column family has almost 1B rows in it.
flush_largest_memtables_at is set to .75, but it seems we hit that almost
continuously. The pattern for this table is heavy writes, and very little
reads. (essentially a clustered log)
Row cache is disabled, key cache is set to 40MB. We have 8GB of heap
associated to the JVM (24GB of physical).
Heap usage is between 6.5 and 7.5GB, mostly.
Advice on what to look at to reduce heap usage here? Surely it's not a
factor of how much data we have in the cluster, is it? (We have gobs of
disk available across this cluster)

How to I stop a form from submitting? I have some validation on my form,
and if the the input isn't correct, then the form should't submit... In my
HTML i have this when clicking submit:
<a href="#"
onclick="setTimeout(function(){document.getElementById('form_4').submit()},
1000);" style="position:static" class="btn-more">Vælg</a>
And the my script looks like this:
$("#form_4 a.btn-more").click(function (e) {
//Validate required fields
for (i = 0; i < required.length; i++) {
var input = $('#' + required[i]);
if ((input.val() == "") || (input.val() == emptyerror)) {
input.addClass("needsfilled");
input.val(emptyerror);
errornotice.fadeIn(750);
e.stopPropagation();
return false;
} else {
input.removeClass("needsfilled");

//if any inputs on the page have the class 'needsfilled' the form will
not submit

X-Robots-Tag Wordpress Subsites
X-Robots-Tag Wordpress Subsites
I am wrestling a bit with implementing a flexible X-Robots-Tag solution
with Wordpress subsites. The issue is that I'd like to be using some
subsites for development and would like to tell any engines to index but
don't display any pages. My understanding is that X-Robots-Tag should take
care of this.
I've tried (our_dev is the subsite):
SetEnvIf Request_URI "^/our_dev/(.*)" is_dev
Header set X-Robots-Tag "noindex, nofollow, noarchive" env=is_dev
and many variations of RewriteRules but the URL isn't changing (which
keeps creating an infinite loop); I am just trying to set a header based
on a particular state.
Any help would be wonderful.

U-Boot. Where does it all begin?
U-Boot. Where does it all begin?
Newbie question here.
I'm looking at a u-boot boardfile, and it has many functions in it. For
example; board_mmc_init(), enet_board_init(), setup_splash_img(), etc.
Most of these functions don't get called from within the boardfile. They
get called from somewhere else. But I can't figure out where.
In Linux kernel boardfiles there's a machine structure. In there we might
have .init_machine = myboard_init. Then myboard_init(void) will call other
functions which will in turn call other functions. I find this style easy
to read.
My question is; does u-boot have an equivalent of .init_machine? Where do
I look to see where everything 'starts'? Who calls all those loose
functions thrown together inside a u-boot boardfile?

Add Swipe Gesture to display the next Item in the Detailed View
Add Swipe Gesture to display the next Item in the Detailed View
From the Collection View I have passed the details I want via segue to the
Detailed View Controller.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
SportsCollectionViewCell *selectedCell = (SportsCollectionViewCell *)sender;
SportsBrowserViewController *targetVC = (SportsBrowserViewController *)
[segue destinationViewController];
targetVC.targetURL = selectedCell.targetURL;
targetVC.sdesc = selectedCell.description.text;
targetVC.stitle = selectedCell.title.text;
targetVC.simage = selectedCell.image.image;
targetVC.scat = selectedCell.category.text;
targetVC.sdate = selectedCell.date.text;
}
I want to now add a swipe gesture to the destination view controller so
that I can get to the next article without having to go back to the main
page. I have added the following to set up the gesture.
UISwipeGestureRecognizer *recognizer;
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self

[recognizer setDirection:UISwipeGestureRecognizerDirectionLeft];
[[self view] addGestureRecognizer:recognizer];
}
-(IBAction)swipeHandler:(UISwipeGestureRecognizer *)sender{
NSLog(@"SWIPE");
}
However, I do not know how to move from here. Could someone point me in
the right direction.
From the Collection View I have passed the details I want via segue to the
Detailed View Controller.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
SportsCollectionViewCell *selectedCell = (SportsCollectionViewCell *)sender;
SportsBrowserViewController *targetVC = (SportsBrowserViewController *)
[segue destinationViewController];
targetVC.targetURL = selectedCell.targetURL;
targetVC.sdesc = selectedCell.description.text;
targetVC.stitle = selectedCell.title.text;
targetVC.simage = selectedCell.image.image;
targetVC.scat = selectedCell.category.text;
targetVC.sdate = selectedCell.date.text;
}
I want to now add a swipe gesture to the destination view controller so
that I can get to the next article without having to go back to the main
page. I have added the following to set up the gesture.
UISwipeGestureRecognizer *recognizer;
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
action:@selector(swipeHandler:)];
[recognizer setDirection:UISwipeGestureRecognizerDirectionLeft];
[[self view] addGestureRecognizer:recognizer];
}
-(IBAction)swipeHandler:(UISwipeGestureRecognizer *)sender{
NSLog(@"SWIPE");
}

Safe trackable links from 301 redirect
Safe trackable links from 301 redirect
I want to create a something where a user can submit a link
(http://www.example.com?key=value) then be returned with a new link which
will redirect to the link provided in a way that is traceable.
(http://trackedlink.com/[trackid]).
I was thinking about adding a get value to the end of the link redirect
eg, http://www.example.com?key=value&trackid=[trackid]
My concern is that although extremely unlikely this may override an
already set get value (trackid). Is there any truely safe way to do this?

Im using jQuery selectable plugin. Im looking for a way to catch the click

I have been reading the code for this plugin but I cant find where the

If I catch the click event on the selectable, it works if I use a

preventing R nested list from being converted to named vector
preventing R nested list from being converted to named vector
I want to create a nested list, for example,
> L <- NULL
> L$a$b <- 1
> L
$a
$a$b
[1] 1
Since I need to do assignment in loops, I have to use the brackets instead
of the dollar, for example,
> L <- NULL
> a <- "a"
> b <- "b"
> L[[a]][[b]] <- 1
> L
a
1
> b <- "b1"
> L[[a]][[b]] <- 1
Error in L[[a]][[b]] <- 1 :
more elements supplied than there are to replace
That is out of my expectation: L becomes a named vector rather than a
nested list. However if the assigned value is a vector whose length
exceeds 1, the problem will disappear,
> L <- NULL
> L[[a]][[b]] <- 1:2
> L
$a
$a$b
[1] 1 2
> b <- "b1"
> L[[a]][[b]] <- 1
> L
$a
$a$b
[1] 1 2
$a$b1
[1] 1
Most of my assignments are longer than 1, that is the reason my code
seemingly worked but at times failed strangely. I want to know if there is
any way to fix this unexpected behavior, thanks.

Problem
The red bullets in the first list are perfect for the first list. However,
the red bullets have issues in the second list:
The bullet size should be larger (large enough to hold a two-digit number)
The bullets should be behind the number
Questions
The first question has me stumped; the second question I can probably use
\defineitemlist to resolve. How would you:
ensure the number is drawn on top of the bullet?
format the lists independently (i.e., larger bullet in second list)?

I thought I could define a named group, but the \defineitemgroup

Xcode 5 and localization of .xib files
Xcode 5 and localization of .xib files
I'm trying to localize a .xib file.
The problem: After clicking the "Localize button" in the inspector, I end
up with a list containing "English" and nothing else, well this is normal.
But usually, as I can remember there is a "+" button which lets you add a
language to this list.
I've asked on apple developer forum, because I'm using a beta version, but
the post has been removed (not sure why).
There's a workaround for this?
Thanks.

take another look at. Is there a way to do this?
I know you can record demos manually, but I don't want to always record my
matches as that takes a lot of effort and disk space. Is there
functionality similar to lastreplay.rep in SC:BW that autosaves your last
demo and overwrites it automatically?

nginx proxied responses terminating/truncating
nginx proxied responses terminating/truncating
I have this nginx config on a host (host1):
server {
...
location /foo {
proxy_pass http://127.0.0.1:8091/;
}
}
The backend nginx config looks like this:
server {
listen localhost:8091;
root /store;
autoindex on;
}
The backend is actually on a different host (host2), and due to our
firewall config, I need to reverse-tunnel the connections (this may be
irrelevant to the question but including for completeness):
ssh -R8091:localhost:8091 host1
This setup is for serving large-ish files (GBs). The problem is I'm
finding that requests are abruptly terminating/truncating short of their
full size, always a bit >1GB (e.g. 1081376535, 1082474263, ...). No errors
in the logs however, and nothing jumps out from verbose debug logging.
There's always a Content-Length in the response too.
After some digging I found that there's a proxy_max_temp_file_size that's
1GB by default. Indeed, from inspecting the FDs of the nginx worker in
/proc, the temp file is actually being filled up to exactly 1073741824
bytes, and at a rate much faster than the downstream client is able to
receive. Lowering it to 1MB mostly makes the problem go away [1] (as
would, I imagine, disabling it with 0 altogether). But why would this be a
problem? If there was a timeout, why no error message, why is 1GB the
default, and why would the downstream client manage to receive a few
additional (varying number of) bytes beyond the 1073741824th byte?
Anyway, just wondering if anyone might have an inkling as to what's up. If
it makes a difference, both hosts are Ubuntu 12.04.
[1] I say mostly because the problem is replaced by another one, which is
that downloads all stop at exactly 2147484825 bytes, which happens to be
0x80000499, but I haven't done enough debugging to determine if this is
between (as I suspect) the frontend server and the client.

others (the same) View.xhtml with BeanType2? i need a kind of
view-inheritance; like to use an EL-Expression like #{BEANPARAM.method}
where BEANPARAM can be BeanType1 or BeanType2...
is this possible or do I need two identival views with different beans?
i have got following:
public abstract class aBean{... methods and variables ...}
@ManagedBean, ViewScoped
public class BeanType1 extends aBean{...only one method overritten...}

, how to hide some panels on a category?
, how to hide some panels on a category?
I'm using BCGControlBar Library(17), there are some panels on a category,
for example : a b and c. Sometimes I want to show a and b, then c should
be hidden, sometime I want to show b and c, so a should be hidden. Now
what I can do is using
CBCGPRibbonCategory::RemovePanel
to remove panel from category, and add it to category when I want to show
it, but I don't like this way, anyone knows a better method? thanks!

c# - WP: navigation to the page?
c# - WP: navigation to the page?
I have 10 xaml pages in my Wp app. In every xaml page, i have webbrowser
method to display html page and its content is like below.
1. //.....//
2. //.....//
...
100. //.....//
I decided to have easy navigation. So, i created two textbox, one is for
xaml page and other is for content (1,2, ... 100) So, what my desire is if
user gives, 5 in first textbox and 10 in second textbox it should open
5.xaml and it should be automatically moved to 10. //...//
I have done the code for first textbox. but i dunno how to code for second
textbox.
Here is my code:
TextBox xaml = new TextBox();
xaml.Width = 150;
xaml.MaxLength = 3;
TextBox content = new TextBox();
content.Width = 150;
content.MaxLength = 3;
int num = 0;
if (int.TryParse(xaml.Text, out num) && num > 0 && num < 11)
{
string site;
site = num.ToString();
NavigationService.Navigate(new Uri("/Page" + site + ".xaml",
UriKind.Relative));
}
else
{
MessageBox.Show("Expected Input Range: 1 to 10");
}

Short message encryption with only javascript to generate it in a URL
Short message encryption with only javascript to generate it in a URL
I'd like to present an idea to you that I think might help the privacy of
the average user. I would appreciate any comment or suggestion on this.
I've been struggling for quite some time now with the need for a simple
tool that I could share and use with my contacts who are only average
users and not familiar at all with any cryptographic technology or the
current tools available.
I'm planning to create a solution where one can easily encrypt a text
message or a file with a single password and send it in email or chat or
through whatever channel to somebody else. The solution should be entirely
platform independent and usable without the need to install any extra
softwares.
There are some text encryption websites out there that run client side
encryption from JavaScript entirely. I find this approach currently the
only possible solution. Also, there are libs for JS that already implement
encryption:
http://crypto.stanford.edu/sjcl/ http://code.google.com/p/crypto-js/
Though the mentioned approaches store the message on their server,
requiring you and your contact to trust it entirely. Because the server
might present a different JS code to the user when visiting it after he
gets the message by steeling the password and so revealing the secret.
While many think that it's not a good idea to do anything regarding
cryptographic tasks in JS, I believe there is a need for a tool that is
really platform independent (can be used on any tablet or PC) and still
incredibly easy to use. The idea behind this is that I believe something
is better than nothing. Sending information in plain text in email for
decades with our current technology is wrong in most cases. There are
times when we do need to share sensitive info via email and the other side
might have any kind of system.
I intend to avoid the use of public key cryptography for the following
reasons: - it is very complicated to setup including the signing of each
others' keys - complicated to use it - the user can loose his keys - most
of the time it needs and external software to be used and installed too -
a single password can be easily shared personally one time with my contact
and he or she can keep it written on a paper wherever
The solution I came up with could be the following:
First of all, the browser and the operating system under it sould be
considered trusted.
There would be a static index.html page with embedded JavaScript. The page
shows a textarea for the message and a textbox for the password. When
hitting enter, the JS code generates a URL that itself will contain the
encrypted message in base64 encoding. After digging I figured that 2000
bytes can be used for URLs just fine in every cases, so 1600 or 800
characters could be enough for short messages. This still needs planning.
So the encrypted message would travel with the URL. The website serving
the index.html would of course use SSL with a valid certificate. While it
seems an easy taks, of course it is not. The JS implementation should be
carefully created to avoid easy attacks on it.
(URL shortener services could be used for it too).
Also, the question stands: How can I make sure that my contact can be
certain about the origin of my message?
Well, the other side has to check if the domain is correct. Beside this,
the implementation must avoid the rest of the attacks. If the URL gets
changed during the travel of the email, then maximum the other side won't
be able to decode the message with the password. That's what I believe.
That it can be implemented this way.
About the file sharing. The solution should have a possibility to browse
for a file, then encrypt it, then put it out for download to the user.
This is just for him to be able to create the encrypted form of the file
without the need for external tools. Then he could upload it to the cloud
of his choice wherever (Google drive, Skydrive etc) and use that link in
the URL of the JS solution to send it to his contact.
So if another link travels with the link, then the file from the remote
host gets downloaded, decrypted and sent for download. All in his browser.
If it's an encrypted message in base64 form, then it gets printed on the
page after decryption (by the user providing his password of course).
Pros compared to other solutions: - no need to implement a storage because
no message nor file will be stored on the server, so the big players'
services could be used - therefore no need to reimplement the wheel
regarding the storage question - no need to trust a 3rd party because the
server could easily be ours because it would be extremely easy to set up
and serve it - easy with even a free provider to host the static
index.html - because of its simplicity, the server can be hardened much
better - easy to encrypt with it in practice - if one needs it, he could
use the index.html by clicking on it from his desktop too, but that's not
part of the original idea
My questions to you all are:
Do you find any flaw in my theory above? Could this really serve the
average people by providing a usable tool for them that is more than
nothing in times when they do need to send sensitive info to others?
Or does anything like that exist yet? Are there any better approaches?
Different technology maybe?
Thank You.

I am ditching the python desk top and writing a zombie game with my

SQLAlchemy-like relationships without SQLAlchemy
SQLAlchemy-like relationships without SQLAlchemy
SQLAlchemy gives me nice relationships between objects. When I change one
object's member, it's automatically added to the other object's list, etc.
However - I don't want to use a DB. I'd like to keep my objects in the
memory. Is there a module that gives this kind of behavior without using
SQLAlchemy?

MySQL utf-8 PASSWORD() function outputs different values
MySQL utf-8 PASSWORD() function outputs different values
I have a question regarding mysql. I've been trying to fix this for quite
some time and am out of ideas.
I have a table that conatins user information. Three of this table's
columns are Username, PW and Famille.
The Username I am interested in is '12234567' and the Famille's value is
'Testé'.
I generated the PW column like so:
UPDATE tablename SET PW = PASSWORD(CONCAT(Username,UPPER(Famille))) WHERE
Username ='1234567'
However, once I try to match the column PW with PASSWORD('1234567TESTÉ')
it doesn't work because the outputted values are different. Any help would
be greatly appreciated!
Thanks

I would like to make a inputfield readonly. I am familiar with the
setDisabled() method in XRM, the downside of this method is that it is not
possible to copy/paste values from the fields.
Is there another way then using javascript/jQuery directly to set the
readonly property on the field by using it's field name?
Kind regards Rim

CPU Utilization of Android dual core device
CPU Utilization of Android dual core device
In android mobile devices, nowadays many models support Dual core
processors. If i want to measure the CPU utilization using top command i
get a single value as 40% or anything.
Consider an example - 50%. Does this mean any of the following ?
Core 1 is completely utilized and Core 2 is free. So 50% out of 100% is
utilized.
50% of Core 1 and 50% of Core 2 is utilized.
How do i say, my application is consuming better CPU ? How do i measure it ?

Logback coloring based on class/package
Logback coloring based on class/package
I've started reading about Logback (currently using log4j and thinking
about switching). I'm interested in the possibilities to color the logged
messages. Browsing through previous questions, I've only seen mentions of
coloring different parts of the message (conversion patterns) or coloring
exceptions.
What I'm interested in, however, is whether logback can color my messages
based on their package or class.
For example, let's say my application is composed of two main components-
a producer and a consumer, and they both are composed of a large
dependency tree. Can I have any message which is logged through the
consumer colored red, and any message which is logged through the producer
colored blue?
Please notice that I don't want this to interfere with log levels (that
is, I still want to have the option to set components to debug/error etc,
ideally without having to mind the coloring.
Thanks!

Set blur event on dynamic boxes
Set blur event on dynamic boxes
I have a page where the user can dynamically add a text input box. I am
wanting to fire an even when the user leaves this input box. This looks OK
on the initial page refresh where there is only one box. In that case the
DOM looks like...
<div id="controls">
<div class="tag" data-tag="1">
<input id="tags_" class="word" type="text" name="tags[]" data-tag="1">
<input id="weights_" class="weight" type="hidden" name="weights[]"
data-tag="1" value="90">
<div class="slider slider-1 ui-slider ui-slider-horizontal ui-widget
ui-widget-content ui-corner-all" aria-disabled="false">
<a class="add-word" href="1" data-tag="1">+</a>
</div>
</div>
...and my js is...
$('.word').blur(function(){
alert("wintas!");
});
So this works OK, but if I add anohter text box dynamically the DOM
becomes...
<div id="controls">
<div class="tag" data-tag="1">
<input id="tags_" class="word" type="text" name="tags[]" data-tag="1">

I have a problem with transfer image from scanner to my application after

Does Zend disable inlineScript helper in ajax context?
Does Zend disable inlineScript helper in ajax context?
I have some javascript that is only required when a certain jQuery dialog
is loaded. I have put it in an external file and referenced it in the
controller as:
$this->view->inlineScript()->appendFile('/theme/flat/scripts/new-post.js');
In my new-post.ajax.phtml file I have the following line:
<?=$this->inlineScript();?>
But I just can't get it to work. There are no script tags or content
inserted.
If I put the same code in a non-ajax controller and view it works fine.
Is it possible that the ajaxContext action helper disables the
inlineScript view helper? Why? And is there a way around it? (I have quite
a few snippets I am pulling in with ajax, and each has its own javascript
code).

Group summary for a boolean field (cxGrid)
Group summary for a boolean field (cxGrid)
How can I have a boolean field in my cxGrid (displayed in the grid as a
checkbox) display a full (group) summary (count) : total issues + solved
(checked) and unsolved (not checked) ? When I check the checkbox,the issue
is solved. When I uncheck it, it is unsolved. Right now, I only managed to
figure out how to display the total amount of issues. What I need to
display is the count of checked and unchecked items in the same field. So
my header (in the example shown below) would display : DATE: 28.8.2013
(Total issues:2) (Solved:1) (Unsolved:1) Is it possible to accomplish
this?

Eclipse not exporting full .apk
Eclipse not exporting full .apk
So I updated my Android Application lately and exported it to a .apk so I
could send it to some other android phones. The exportation finished
without errors, and everything was fine. But when I installed the app
using the .apk, it seemed like I got an older- or half version of the app.
Some functions doesn't work at all, and the app takes about 50% less space
on the other phones. On my own phone, the app works perfectly and takes
all the space it's supposed to. The wierd thing is that I'm using the same
.apk to install the app on both my own phone and the other phones.
Is there a possible error or solution for this? I really need the new
functions, or the app won't work well! I also searched for a solution for
hours, so don't blame me if there's already a same question out there.

Cyrillic strings in H2 database
Cyrillic strings in H2 database
I have a problem persisting Cyrillic strings to in-memory H2 database.
Java displays those strings properly, but after I save and retrieve
strings from H2 using Hibernate they are displayed as blank spaces.
The strange thing is those blank-strings are actually grouped - pressing
left-right shifts only one space, but pressing CTRL+right jumps a few
spaces. Is this a Java or H2 issue and how do I work around it?

is:
@RenderSection("scripts", required: false)
So I thought maybe putting this in my MyArea _Layout:
@section Scripts {

But that doesn't render the script where I want it to. So how do you get
it to put the scripts you make in your views to put it into the section

Is there a way to redirect to a specific page using Tank_auth in Codeigniter?
Is there a way to redirect to a specific page using Tank_auth in Codeigniter?
I'm wondering if there's a way to redirect to a specific page (like
adminpanel_view) in Tank_auth. I looked at the Auth.php controller but
could not figure out how to redirect, if it's even possible..
I tried this:
public function login() //login functie
{
$this->breadcrumbs->page = array('link'=> base_url().'auth/login'
,'title' => 'Login');
$data['breadcrumbs'] = $this->breadcrumbs->get();
if ($this->tank_auth->is_logged_in()) {
// logged in
redirect('members/cpanel');
}

UFW blocking some allowed internal connections
UFW blocking some allowed internal connections
My set up is this:
Server 1 (192.168.1.1) - nginx (load balance) - Ubuntu 12.04 LTS
Server 2 - uwsgi - Debian 7.1
Server 3 - uwsgi - Debian 7.1
UFW on server 2 and server 3, is blocking certain requests coming from
server 1 (nginx) and is showing up in nginx error log as "upstream timed
out". Traffic between nginx and uwsgi server is all on a private network.
This is UFW setup on uwsgi servers:
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip
To Action From -- ------ ----
Anywhere on eth1 ALLOW IN Anywhere
Anywhere ALLOW IN 192.168.1.1
Anywhere (v6) on eth1 ALLOW IN Anywhere (v6)
Example UFW block in syslog:

If I disable UFW on Uwsgi servers the timeouts in nginx stops. At the
moment the timeouts/blocks are mostly frequent ajax calls (every 2mins),
but not exclusively.

Struggling to move Web Role to a smaller vmsize
Struggling to move Web Role to a smaller vmsize
I want to move my web role to a smaller VM size for cost saving purposes.
I changed the vmsize attribute in WebRole in the ServiceDefinition.csdef
accordingly. On publishing I received the following error:
Total requested resources are too large for the specified VM size
So I then reduced the size of the local storage resources in the
ServiceDefinition.csdef. Then I got the error:
The size of local resources cannot be reduced. Affected local resource is
DataFiles in role Website.
From what I have read online, I will need to delete the deployment and
republish it. But this will assign a new IP to my cloud service. I can't
have this happen.
Is there another solution to my problem?

java code with only a few main entry
java code with only a few main entry
I want to read HBase source code, starting with test cases. I've searched
under the folder /src/test/java, and found
"org/apache/hadoop/hbase/PerformanceEvaluation.java",
"org/apache/hadoop/hbase/rest/PerformanceEvaluation.java"
"org/apache/hadoop/hbase/regionserver/DataBlockEncodingTool.java"
"org/apache/hadoop/hbase/regionserver/EncodedSeekPerformanceTest.java"
have main entry.
But there are many more test source files under the same folder. So I
wonder why only four classes have main entry. Is it sufficient to test
hbase with only the above four main entry?
Since I'm a newbie for Java open source project, anything related will
help. Thanks.

Necessity of synchronized on local variable
Necessity of synchronized on local variable
In the JSON-java library (org.json.JSONArray) I have found this code
snippet with a synchronized block around a method-local variable
public String toString(int indentFactor) throws JSONException {
StringWriter sw = new StringWriter();
synchronized (sw.getBuffer()) {
return this.write(sw, indentFactor, 0).toString();
}
}
I do not understand the necessity for the synchronization here, as the
StringWriter is only local to the given method (and, why the
synchronization is on the Buffer). Is the synchronization really necessary
here, and if, why?

JSlider get length of bar
JSlider get length of bar
So I'm wondering if there's a way to get the length of the bar of a
JSlider when it is displayed on a JPanel. Note that I'm looking for the
length of the actual bar the knob slides on, not the size of the component
itself. Thanks in advance.

globaltoLocal in addchild
globaltoLocal in addchild
I have an enemy that adds an attack movie clip. More specifically, this
attack movie (We'll call it masterAttack) clip is a blank movie clip that
acts like a super class, that will hold other attacks like a weak and
strong attack. So when my enemy attacks using a timer, it adds the
masterAttack on a global to local point.
Below is the Enemy timer attacking a tile the player is on:
if (Main.tileset[k].tileMiddle.hitTestObject(Main.player.visionPoint))
{
this.addChild(masterAttack);
var pt:Point = this.enemymagic.globalToLocal(new
Point(Main.tileset[k].x, Main.tileset[k].y));
masterAttack.masterEnemyAttackTimer.start();
this.masterAttackx = (pt.x);
this.enemymagic.y = (pt.y);
}
And Below is the masterAttack timer:
function mastertimer(event:TimerEvent) {
addChild(sludgeball); //This is one of the many
attacks pickable by the masterAttack
sludgeball.enemyattackTimer.start();
if (this.sludgeball.currentLabel == "End") {
this.sludgeball.gotoAndPlay(1);
masterEnemyAttackTimer.stop();
if (masterEnemyAttackTimer.running == false)
{
attackStop = true;
this.parent.removeChild(this);
removeChild(sludgeball);
}
}
My problem is, on the first run, the masterAttack will attack the player
wherever it is, then remove itself, which is good. Then the next time it
runs, the masterAttack is not hitting the player. It's as if the
globaltoLocal isn't working after the first run.

Im new to programming in general and am currently trying to get started
building my first mobile app on android.I am thinking of creating an app
which would send requests to a server, which would then process it and
load the data in the app, which the user would then view.
I have the following questions:
Communicating with the server
How would i program the app so that it is able to communicate with the
server (I'm planning to use a web host like godaddy/hostgator etc).
Logging in & Identification
How would i go about uniquely identifying each user of the app?Would it be
possible to identify and create an account for any user who downloads my
app from the marketplace and runs it for the first time(Maybe through the
gmail account they use for the android marketplace?) or would i have to
make each user manually sign up and login the first time they run my app?
I would appreciate it if someone could tell me the best way to get started
and how best to go about developing such an app.
Thanks!

Curious function problem (EDIT: Not so curious, but didn`t see it at the time of writing)
Curious function problem (EDIT: Not so curious, but didn`t see it at the
time of writing)
This one is directly from my head and although it could be something
trivial I do not see the way to attack it but the problem looks
interesting and I want to share it with you, here it is:
Let us define function $f$ as $f(x)=\displaystyle\frac{\pi}{x}$.
Now, I wonder is there an easy way (or any way?) to prove (or disprove)
that for every interval $[x_1,x_2]\subset \mathbb R\setminus\{0\}$,
$x_1\neq x_2$ there exist irrational number $x_0\in [x_1,x_2]\setminus
\{\displaystyle\frac{a\pi}{b}|\displaystyle\frac{a}{b}\in\mathbb Q\}$,
such that $f(x_0)$ is rational number, in other words, that every interval
$[x_1,x_2]\subset \mathbb R\setminus\{0\}$ contains at least one
irrational number $x_0$ such that $f(x_0)$ is rational and $x_0$ is not
rational multiple of $\pi$.
Any ideas?

How do I go through directories to see if they have files and display only the directories with files?
How do I go through directories to see if they have files and display only
the directories with files?
Trying to create an Array or something to pass to my view.
The Array/something is supposed to store which directories have files in
them.
Then in my view I want to display only directories with files in them.
def index
@filter = params[:filter]
@type = params[:type]
@content = [] #maybe?
if
directory_path = "public/files/marketing/voip"
directory = Dir.glob("#{directory_path}/#{@filter}/#{@type}")
directory.each do |data| # not sure???
if File.exists?(data) && !File.directory?(data)
# not sure???
@content = Array.new("#{@type}")
end
@view = 'types'
end
#Loop through directories to see if files exist
#If files exist add directory name to @array
end
My view:
<%# Loop through array and create html view for each folder %>
# no idea?
<% @content.each do |o| %>
<% if type.exists %>
<div class="row images">
<div class="span3">
<h5 class="pagination-centered">
<%= link_to (image_tag "/img/folder.jpg", alt: "Buyer's Guides", width:
"75px"), action: "index", filter: @filter, type: "buyers_guides" %>
<%= link_to "Buyer's Guides", action: "index", filter: @filter, type:
"buyers_guides" %>
</h5>
</div>
</div>
I am new to Ruby on Rails, any suggestions?

KeyEventArgs and MouseEventArgs
KeyEventArgs and MouseEventArgs
I'm trying to make a button that handles both enters and clicks. I've set
up my sub procedure to handle both keyups and mouse clicks, however I
cannot access MouseEventArgs from EventrArs nor KeyEventArgs from
System.EventArgs. How can I do such?
