can the order of code make this program faster?
can the order of code make this program faster?
Hi this is my first post, I am learning how to write code so technically I
am a newbie.
I am learning python I am still at the very basics, I was getting to Know
the if statement and I tried to mix it with another concepts(function
definition,input,variables) in order to get a wider vision of python, I
wrote some code without a specific idea of what I wanted to do I just
wanted to mix everything that I have learned so far so probably I over do
it and its not practical, it "works" when I run it.
The question that I have its not about how to do it more efficient or with
less code it is about the order of code in all programming in general.
Here I'll show 2 different order of code that gives the same result with
exactly the same code(but with different order).
on (1) I define a function on the first line.
on (2) I define the same function closer to when I use it on line 5.
which one is faster? is defining a function "closer" to when I need it
impractical for the complexity of larger programs(but does it make it
faster), or defining a function "far" from where I need it makes a larger
program slower when running(but also more practical).
(1)
def t(n1,n2):
v=n1-n2
return abs(v)
a = int(input('how old are you? \n'))
b = int(input('how old is your best friend? \n'))
c=t(a,b)
if a==b:
print ('you are both the same age')
else:
print('you are not the same age\nthe difference of years is %s
year(s)' % c)
input()
(2)
a = int(input('how old are you? \n'))
b = int(input('how old is your best friend? \n'))
def t(n1,n2):
v=n1-n2
return abs(v)
c=t(a,b)
if a==b:
print ('you are both the same age')
else:
print('you are not the same age\nthe difference of years is %s
year(s)' % c)
input()

NSMutableArray with Cyrillic text
NSMutableArray with Cyrillic text
I try to load words from a txt file using following code:
NSURL *filePath = [[NSBundle mainBundle] URLForResource:@"testFile"
withExtension:@"txt"];
NSString*stringPath = [filePath absoluteString];
NSData *drfData = [NSData dataWithContentsOfURL:[NSURL
URLWithString:stringPath]];
NSString *str = [[NSString alloc]initWithData:drfData
encoding:NSUTF8StringEncoding];
Works great, even if I use cyrillic words ("ïðèâåò").
Now, I use following code to add each word as object to my NSMutableArray.
To detect what is a word, I separated them by comma in my testFile.txt
document.
int nLastPoint = 0;
int nCount = 0;
for (int i = 0; i< str.length; i++) {
if ([[str substringWithRange:NSMakeRange(i,
1)]isEqualToString:@","]) {
[lst_wordlist addObject:[[[str
substringWithRange:NSMakeRange(nLastPoint, nCount)]
stringByTrimmingCharactersInSet:[NSCharacterSet
whitespaceAndNewlineCharacterSet]] uppercaseString]];
nLastPoint = i+1;
nCount = 0;
}else{
nCount++;
}
}
int nLength = 0;
for (int i = 0; i< [lst_wordlist count]; i++) {
if ([[lst_wordlist objectAtIndex:i]length]>nLength) {
nLength = [[lst_wordlist objectAtIndex:i]length];
}
}
NSLog(@"%@",lst_wordlist);
Works great, again ONLY if I use english words. With Cyrillic words
doesn't work.
This is my NSLog when I use a cyrillic word.
"\U041f\U0420\U0418\U0412\U0415\U0422",

Any ideas? How can I fix it? I tried to change debugger from LLDB to GDB,
doesn't fix the problem.

How do I alternate DIV colors in a while loop?
How do I alternate DIV colors in a while loop?
Let's say I have a code that looks like this:
while ($info = mysql_fetch_assoc($data_p)) {
$name = stripslashes($info['name']);
$desc = stripslashes($info['description']);
$desc = substr($desc, 0, 150);
$price = stripslashes($info['price']);
Print "<div style=\"width:600px; height:150px; border:1px solid black;
overflow:hidden\"><div style=\"height:148px; width:25%; border:1px
solid red; float:left\"><center><img src=\"".$picture."\"
height=\"120\" width=\"120\" style=\"margin-top:15px\"
/></center></div><div style=\"height:150px; width:50%; border:1px
solid blue; float:left; text-overflow: ellipsis;
padding-top:5px\"><center><font size=\"+1\"><b><a
href=\"result.php?product=".urlencode($name)."\">".$name."</b></a></font><br><br>".$desc."...</center></div><div
style=\"height:150px; width:24%; border:1px solid green;
float:left\"><center><h1>$".$price."</h1><button>Add to
Cart</button></center></div></div>";
The main DIV that is first defined in the while loop I would like to
alternate two shades of grey. So in the results it would look like light
dark light dark etc...I've tried simply repeating the echos again with a
different color but that makes duplicates of each result. Is there a way
to do this?

Finding repetitive substrings
Finding repetitive substrings
Having some arbitrary string such as
hello hello hello I am I am I am your string string string string of strings
Can I somehow find repetitive sub-strings? In this case it would be
'hello', 'I am' and 'string'.
I have been wondering about this for some time but I still can not find
any real solution. I also have read some articles concerning this topic
and hit up on suffix trees but can this help me even though I need to find
every repetition e.g. with repetition count higher than two?

Definitive C Input/Output Guide
Since the semester recently started a lot of similar questions regarding
IO in C (and C++) keep pouring in and the answers are often the same:
while(!feof()) is bad, use fgets() instead of scanf(), etc.
Do you think a community wiki is needed so all the duplicate questions
could be directed to that single answer? Or do you think they are still
sufficiently different so that those who ask would benefit from a question
tailored to their demands? Some just downvote and comment suggesting
posting on homework.stackexchange.com, but this doesnt't help.
After reading How should duplicate questions be handled? and What's the
etiquette for answering two similar questions? it seems to boil down to
the question how similar are two posts to be considered duplicate.
If you feel that most of the questions were indeed duplicates and that
this could grow into a community wiki page, please post your tricks of the
trade on IO in C including use, best practices, no-nos, notes on history
or implementation details and links to useful resources.

knitr 1.4.1 ending comment in chunk do not display correctly
I am using knitr 1.4.1 and have observed that when the last line of a
chunk (.Rnw file) is a comment, this comment does not display as the
previous comments.
Her is a minimal example:
\documentclass[a4paper]{article}
\begin{document}
<<chunk, echo=TRUE>>=
## comment before output
x <- sum(1:10) ## sum number from 1 to 10
x
(x <- sum(1:10)) ## sum number from 1 to 10
## comment after output
x
## final comment
@
\end{document}
With knitr 1.4.1 all comments but the last one are displayed in italic.
Any hint on how I could make the last comment look as the other ones would
be welcome.

What is the supertype of all functions in Scala?
I know I can do instanceOf checks against Function1 or Function2 etc but
is there a generic way to see if something is function or not (it can have
arbitray number of args). I tried defining something like this:
type FuncType = (Any*) -> Any
But that did not work either. Basically I have some code that looks like
this:
call = (name: Any, args: Any*) -> if name.isFunction then
name.castAs[Function].apply(args) else name
aFunction = (name: String) => "Hello " + name
notAFunction = "Hello rick"
call(aFunction, "rick")
call(notAFunction)

Inputting values to a string as a website URL for the page to be downloaded
Inputting values to a string as a website URL for the page to be downloaded
I'm messing around with the System.Net library in C# and I'm trying to
simply have it set up such that you enter an url and it will take that as
a string and put that into the parameter for the URl in the
Client.DownloadString() field.
Here is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
namespace StringDownloadTest
{
class GetInformation
{
string EnterString;
public string InputString()

EnterString = Console.ReadLine();
return EnterString;
}
}

R.InputString();
string downloadedString;
System.Net.WebClient client;
client = new System.Net.WebClient();
downloadedString = client.DownloadString(R.InputString());
Console.WriteLine("String: {0}", downloadedString);
}
}
}
Any help here, it will compile but the program crashes.

Any good way to save an unsubmitted form?
I know it's a difficult task, but is there any good way to save form input
when the user navigates to a different page without submitting, so when
they come back they won't have to re-enter the info?
I'm using Rails 4, Simple Form, and jQuery, but I'm open to any solution
that isn't an ugly hack.

bellow is correct but the (00:30) is not correct!
Anyway, lets say I have set the time to (00:30) by $strtotime = '00:30';
at the start of the PHP code. now I want to add and/or subtract the
$offset/3600 value from the (00:30).
The $offset/3600 value is a time difference between two timezones if you
are wondering what that is and where its values coming from by the way.
I am trying to use the code bellow:
<?php
$strtotime = '00:30';
if (0 > $offset)
{
// For negative offset (hours behind)
$time = $offset / 3600 + (00:30);
}
elseif (0 < $offset)
{
// For positive offset (hours ahead)
$time - $offset / 3600 - (00:30);
}
else
{
// For offsets in the same timezone.
$time = "in the same timezone as";
}
echo "{$strtotime}";
?>
this code will only echo 00:30 and it wont add or subtract the $offset /
3600 value from it!
is there anything else that i need to do? or I am totally on the wrong path?
what I am trying to do might be quite be simple but I don't know how to
get it working.

Multiple jquery dialogs in index.php
Multiple jquery dialogs in index.php
The general idea is to make a site that looks like windows enviroment, so
I have add two icons for example and when someone click on them, takes two
different dialog boxes.
In to my site's index page I have add this inside head tags:
<link rel="stylesheet"
href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css"
/>
<script
src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<!-- JQUERY DIALOG SCRIPT -->
<script>
var $JQ_ = jQuery.noConflict();
$JQ_(function () {
$JQ_("#rl_module_dialog").dialog({
autoOpen: false,
width: 'auto',
resizable: false,
show: {
effect: "fade",
duration: 250
},
hide: {
effect: "fade",
duration: 250
}
});
$JQ_("#opener").click(function () {
$JQ_("#rl_module_dialog").dialog("open");
});
});
</script>
I also have two separated php files that are icluded into my index page
and they contain this...
First:
<div id="rl_module_dialog" class="rl_module_dialog" title=""><?php include
'**/**/something.php'; ?></div>
<div class="nm_icon" id="opener"><div class="icon"> </div></div>
Second
<div id="rl_module_dialog" class="rl_module_dialog" title=""><?php include
'**/**/something_else.php'; ?></div>
<div class="vath_icon" id="opener"><div class="icon"> </div></div>
If I don't include the second one, dialog works fine. If I place them
both, none is working! There is any way to use my jquery dialog script for
more than one dialog in same page?

Is there a way to source cron jobs from a file
Is there a way to source cron jobs from a file
One of our servers has around 20-25 different cron jobs scheduled on it.
Usually, we periodically check-in the cron jobs to a file in the repo
using crontab -l > cron.jobs
While bringing up a new server, which is a replica of the previous server
(in terms of OS and deployed code base), is it possible to source the cron
jobs for the new server from a file containing valid cron jobs?

Lua source code manipulation: get innermost function() location for a given line
Lua source code manipulation: get innermost function() location for a
given line
I've got a syntactically correct file with Lua 5.1 source code.
I've got a position (line and character offset) inside that file.
I need to get an offset in bytes to the closing parenthesis of the
innermost function() body that contains that position (or figure out that
the position belongs to the main chunk of the file).
I.e.:
local function foo()
^ result
print("bar")
^ input
end
local foo = function()
^ result
print("bar")
^ input
end
local foo = function()
return function()
^ result
print("bar")
^ input
end
end
...And so on.
How do I do that robustly?

AngularJS: Can you get a 'digest in progress' error from multiple $scope.$apply() calls?
AngularJS: Can you get a 'digest in progress' error from multiple
$scope.$apply() calls?
In a large application where you might have a large scope, if you call
$scope.$apply multiple times in rapid succession, can you get a 'scope
already in progress' error?
E.g, I have a directive which is linked to the bootstrap switch plugin.
This directive simply shows an on/off switch which the user can click to
toggle a boolean value as true/false. Each time the user clicks this
button, my directive does a $scope.$apply() in which one scope variable is
changed to reflect the new state of the switch (on or off).
I was worried that if a user clicks the switch in rapid succession, I
might get the 'digest already in progress' error. However, that isn't the
case, each time things go very smoothly and the scope value is updated
everywhere instantly despite multiple $scope.$apply() calls being fired.
Is this because $scope.$apply is optimized somehow so it doesn't run a
full digest, but only updates those values which were changed, or is it
just because my scope is relatively small at the moment so the full digest
isn't taking long to be run?

AngularJS: ng-repeat in directive with isolated scope and $last
AngularJS: ng-repeat in directive with isolated scope and $last
I am trying to catch $last property to be notified when ng-repeat finishes
off. I've created special directive for that (ngRepeatDoneNotification).
Ng-repeat applies to another element directive (unit). So, there is a
construction with three directives:
<unit ng-repeat="unit in collection" ng-repeat-done-notification
id="{{unit.id}}"></unit>
Once I set scope to be isolated, $last disappeared in my notifier directive.
App.directive('ngRepeatDoneNotification', function() {
return function(scope, element, attrs) {
if (scope.$last){ // ISSUE IS HERE
window.alert("im the last!");
}
};
});
App.directive('unit', function() {
return {
restrict: 'E',
replace: true,
scope: {id: '@'}, // ONCE I ISOLATE SCOPE, $last DISAPPEARED
templateUrl: '/partials/unit.html',
link: function(scope, element) {}
}
});
I've create jsFiddle http://jsfiddle.net/4erLA/1/

Textbox/input text element longer than it should be
Textbox/input text element longer than it should be
So the problem is that in my div around listbox(select) + textbox(input
text) + button(input submit) I have width:250px for the whole div and for
the each thing inside it I have width:100%.
That makes me assume that they should logically fill the space inside that
div. But the problem is that the textbox(input text in the fiddle) is
kinda longer(or the other elements are shorter?).
Any ideas why and how to solve this problem?
Demo: http://jsfiddle.net/xXVHu/15/
In my whole code all the divs I have have some kind of meaning so if you
feel like they are useless, they aren't!

My problem is that I don't want my User Entity to have references to
Course, because not every application will make use of the CourseBundle.
Do I have to create CourseAssignedStudents and CourseAssignedTeachers
entities which represents the join tables?
So I can do something like:
$users = $this->getDoctrine()->getEntityManager()
->createQuery('SELECT user FROM ApplicationSonataUserBundle:User user
LEFT JOIN CourseBundle:CourseAssignedStudents cas WITH
cas.student_id = user.id
WHERE cas.course_id IN (SELECT cat.course_id FROM
CourseBundle:CourseAssignedTeachers cat where
cat.teachers_id = :uid)
GROUP BY user.id')
->setParameter('uid', $this->getUser()->getId())
->execute();
I'm new to Doctrine and having a hard time trying to figure out howto
write the query below with Doctrine2 in Symfony2 which gives me a list of
User objects as result.
Query description: A teacher must get a list of users that are assigned to
the courses he has been assigned to as teacher
Select * from fos_user_user as user
LEFT JOIN course_assigned_students as cas ON cas.student_id = user.id

Extraction Of Face From a Bitmap
Extraction Of Face From a Bitmap
After being given suggestions to use circular crop i implemented it in my
application to use to extract face from the bitmap but its too inefficient
i mean its of no use and similar to cropping from the rectangular face.
Now here is what i have done up til now:
Launched Camera
Taken Picture
Detected The face in the Picture
Painting a rectangular window in the area face has been detected
Now the serious issue am facing is getting face from that bitmap. I just
want to get the face. Ignore all the other details that were in the face
detection window. If it was matlab it could have been too simpler with the
help of edge detection techniques and segmentation algorithms and
function. I want to know how can i do the same process in android
application? plz do share the code snippets if u know of any. This is
taking too much of my time and i just want to get over with this face
extraction part.

usage of setTimeout function in AJAX
usage of setTimeout function in AJAX
I.m currently following a tutorial about how to load content from a MYSQL
db without reloading the page.
I just want to understand the use of setTimeout in this code. What's it
for? I tried removing that part and ajax still works. Why would you need
to delay a task, isn't ajax meant to be realtime update?
// load
$(document).ready(function () {
done();
});
// timeout function
function done() {
setTimeout(function () {
updates();
done();
}, 200);
}
// fetch data from db
function updates() {
$.getJSON("update.php", function (data) {
$("ul").empty();
$.each(data.result, function () {
$("ul").append("<li>ID: " + this['msg_id'] + "</li><br
/><li>ID: " + this['msg'] + "</li><br />");
});
});

Visualizing intersections between online communities
Visualizing intersections between online communities
Let's say you wanted to map the intersections between n different online
communities. For example:
80% of CrossValidated users also have a Stack Overflow account
50% of Hacker News users also have a Reddit account
etc.
What would be a good way to visualize this? Any examples of existing
diagrams?
I've seen this question, which provides an answer. But I'm curious to know
if there are other visualization techniques that would specifically lend
themselves to comparing the relationships between communities.

Paypal DirectPayment automatically calculate shipping cost?
Paypal DirectPayment automatically calculate shipping cost?
Paypal has this shipping fee calculator that is automatically added when
the customer reviewed the purchase in Paypal website.
But that calculator only works for payment with Paypal account (Express
Checkout) and doesn't work for Credit Card (Direct Payment) payment.
Must I write my own shipping cost calculator in my app?
Sorry for the broad question, but I can't seem to find this info on Google.
Thanks

High Availability on Windows Azure Websites
High Availability on Windows Azure Websites
One of my main apps is hosted on Windows Azure's Websites platform. Given
last night's downtime, I realized that I need something that allows my app
to stay online if Azure decides to go to hell again.
My current setup is 1 WAWS instance (w/ autoscaling set to 1..3 instances
@ 70% CPU) and SQL Azure as a backend.
I really enjoy having WAWS's automatic git deployment feature and would
rather keep it (Web Roles can't autodeploy easily afaik), but what other
solutions could I use to reach HA + lower latencies for most of my
clients?
I've read about/though about the following scenarios:
Keep it as is and suck it up if Azure goes down again,
Generate additional regions using the same autodeploy scripts [but I'd
have to mirror my SQL Azure DBs somehow)
Move to Web Roles/VMs w/ traffic manager and self-host my DBs on my own
[either keeping SQL Server or moving to MariaDB]
Move to Amazon, Rackspace or whatever allows me to keep
What would you suggest?

jQuery acts strange in Chrome with AJAX (example)
jQuery acts strange in Chrome with AJAX (example)
Im experiencing a strange issue in Chrome (or new Opera browser) and was
hoping you could shed some light to it.
Edit: Live example:
www.wcore.cz/demo/cms
login: demo password: demo
If you go to "Mùj profil" -> "Upravit" -> "Ulozit" it shows loading in
Firefox, IE etc, but not in Chrome.
I want to display a loading status to a user after he clicks an element
but it is not working when I have async=false set up in my Ajax call. It
basically waits until the call is completed and after then shows fills the
element with the "loading". It works just fine in FF, older Operas, IE..
I know that this explanation might be litle confusing, but someone could
know whats this all about.
Thank you for any tips.
Im experiencing a strange issue in Chrome (or new Opera browser) and was
hoping you could shed some light to it.
Edit: Live example:
www.wcore.cz/demo/cms
login: demo password: demo
If you go to "Mùj profil" -> "Upravit" -> "Ulozit" it shows loading in
Firefox, IE etc, but not in Chrome.
I want to display a loading status to a user after he clicks an element
but it is not working when I have async=false set up in my Ajax call. It
basically waits until the call is completed and after then shows fills the
element with the "loading". It works just fine in FF, older Operas, IE..
I know that this explanation might be litle confusing, but someone could
know whats this all about.
Thank you for any tips.
Change layout of the built-in application
Change layout of the built-in application
Is it possible to change the layout of the built-in application of the
Android?
I have Samsung S Duos and I want to change layout of some
application(dialer, SMS messenger and phone book(contacts) are not so
user-friendly for dual SIM cards)
Is it possible to make buttons of this applications bigger or smaller or
to add a new option (sub menu)?
If yes, is there easier way than rewriting and compiling whole Android
source? Or maybe there is an option to change the phone book(contacts) and
reinstall it as a new application?
Any help is appreciated

How prove this $\sum_{k=1}^{n}\frac{k}{3^k-2^k}
How prove this $\sum_{k=1}^{n}\frac{k}{3^k-2^k}
prove that $$\sum_{k=1}^{n}\dfrac{k}{3^k-2^k}<\dfrac{5}{3}$$
my idea: use $$3^k-2^k>2^k(k\ge 2)$$ then $$\Longleftrightarrow
1+\sum_{k=2}^{n}\dfrac{k}{3^k-2^k}<1+\sum_{k=2}^{n}\dfrac{k}{2^k}<1+\sum_{k=2}^{\infty}\dfrac{k}{2^k}=1+\dfrac{3}{2}>\dfrac{5}{3}$$
use this methods,I can't prove it
other idea: $$3^k-2^k>2\cdot 2^k(k\ge 3)$$
But This same can't prove it
so This problem have other nice methods? Thank you

Change Python version in Maya
Change Python version in Maya
I'm trying to change the version of python within maya. Specifically, I
want maya (maya 2013) script editor to use python2.7 and all other
packages/modules attached to that version. I also want to be able to
import pymel and maya from eclipse.
I've tried following this response but no luck. Maya still points to its
default version.
From python, i try to import pymel with
import pymel.core as pm
and I get an error that reads
File "", line 1, in File

Trying to pass images from a model/herlper file to a slideshow in

I have a controller pages.php:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: image

A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: pages/home.php
Or is it completly wrong I should point out that this site will not have
access to a database.
When I have the array in the view file it works.
What I am trying to do is have a different model/helper file for each page
as each page of this controller will have a slideshow but each with
different images. So rather than recreating the view part countless times
I want to simply have a new array for each page. I was thinking of using
something like:
$this->load->helper('pages/'.$page);
-or-
$this->load->model('pages/'.$page.'.php');
so each page has its own model/helper filer but obvioulsy as I cannot get
the first bit working I have no idea if this second bit will work.
Any help will be very much appriciated

Scala parameters pattern (Spray routing example)
Scala parameters pattern (Spray routing example)
Sorry about the vague title...wasn't sure how to characterize this.
I've seen/used a certain code construction in Scala for some time but I
don't know how it works. It looks like this (example from Spray routing):
path( "foo" / Segment / Segment ) { (a,b) => { // <-- What's this style
with a,b?
...
}}
In this example, the Segements in the path are bound to a and b
respectively inside the associated block. I know how to use this pattern
but how does it work? Why didn't it bind something to "foo"?
I'm not so interested in how spray works for my purpose here, but what
facility of Scala is this, and how would I write my own?
Thanks, Greg

swf embed works only for selected domains.
swf embed works only for selected domains.
Since about a week or two the swf embed feature stopped working for my
website. I realized that it stopped working for a few websites but was
still working for soundcloud.com. After doing some research i was able to
pinpoint the issue to a single open graph tag.
A website containing the following does seam to work:

So it basically boils down to changes in the domain presented in the
og:video tag (). There used to be a whitelist of websites enabled to embed
swf on facebook a few years ago. The idea was dropped but I think that
Facebook just got back to it.
How can I get in touch with facebook to resolve this issue? If a
whitelisting is needed how do I ask for being whitelisted?

So it basically boils down to changes in the domain presented in the
og:video tag (). There used to be a whitelist of websites enabled to embed
swf on facebook a few years ago. The idea was dropped but I think that
Facebook just got back to it.
How can I get in touch with facebook to resolve this issue? If a
whitelisting is needed how do I ask for being whitelisted?

How do I extend the String class?
How do I extend the String class?
Extending core classes in javascript is dead easy. I get the impression
it's not quite so easy in C#. I was wanting to add some things to the
String class so that I could do stuff like:
string s = "the cat's mat sat";
string sql = s.smartsingleQuote();
thus giving me
the cat''s mat sat
Is that even feasible, or do I have to write a function for that?

rcs checkout without touching the current working file
rcs checkout without touching the current working file
The idea is somehow ridiculous, but still I'm wondering whether there is
an actual way.
My object: I would like to view a older version of a RCS file without
touching the latest working version. Below are my thoughts:
Method 1: check out the older version to another directory (ridiculous
since the concept looks totally wrong)
Method 2: create another branch based on the older version and then put
the file into the branch (but inevitably, the checking out of the older
version still need to over write the latest working file one time at
least)

Batch jobs - prevent concurrency
Batch jobs - prevent concurrency
I have several batch jobs running on a SAP Java system using SAP Java
Scheduler. Unfortunately, I haven't come across any documentation that
shows how to prevent concurrent executions for periodic jobs. All I've
seen is "a new instance of the job will be executed at the next interval".
This ruins my fi-fo processing logic so I need to find a way to prevent
it. If the scheduler API had a way of checking for the same job
executions, this would be solved but haven't seen an example yet.
As a general architectural approach, other means to do this seems like
using a DB table - an indicator table for marking current executions - or
a JNDI parameter which would be checked first when the job starts. I could
also "attempt" to use a static integer but that would fail me on clustered
instances. The system is J2EE5 compliant and supports EJB 3.0, so a
"singleton EJB" is not available either. I could set the max pool size for
a bean and achieve a similar result maybe.
I'd like to hear your opinions on how to achieve this goal using different
architectures.
Kind Regards,

Is it possible to use fingerprint scanner for authenticating users on a web application?
Is it possible to use fingerprint scanner for authenticating users on a
web application?
I have a web application created in asp.net which is being authenticated
using conventional username/password method. This application is just for
managing employees data and this authentication is fine, but a problem is
coming. currently all daily wage employees comes at the about same time
which makes a long queue before the receptionist and quarrel over their
time that they are standing here for last 5 or 10 minutes for getting
entry. Right now the BI is to collect a predefined amount from daily wage
workers before giving them entry, and if they are late then fine is also
added to this amount. This step of collection and verifying time take
at-least 1 minute - 3 minutes depending upon the quality of receptionist,
which make the exact time employee late. I had increased the late time in
backend but this was not practical as genuine late comers were also
granted entry without fine.
The only solution that comes to me is to getting some bioscanner installed
and linking them to the server. However I have never used a fingerprint
scanner before and just need to know it is fisible or not in web
environment.
It is a web application because their office are having 6 branches.

weird bug in ios vinyl emulation source code
weird bug in ios vinyl emulation source code
I need help for a small test that I'm doing with some part of code that I
found here :
http://blog.weareglow.com/2011/01/vinyl-scratch-emulation-on-iphone/
The original source code has a bug very weird. After a while the velocity
become strange and stay at ~ 22000 (just on slow movement, not in normal
or fast speed) at a special position in the stream.
I made a project to reproduce the bug. (Here
https://bitbucket.org/ppeau/ios-ave/src) I'm using always the same track
and the bug arrived always at the same position.
I'm not able to understand what is the problem. So I'm looking for a smart
one who able to explain what is the problem and how to resolve it.
Thank for all

Correct Field Name For "Album Artist" ID3 Tag In SoX With LAME
Correct Field Name For "Album Artist" ID3 Tag In SoX With LAME
I've got SoX compiled with LAME, and it works fine, I can make an .mp3
file with common ID3 tags.
But I can't figure out what to call the "Album Artist" field so that I can
specify a value. For example:
sox -n --comment "Title=Sweep" --comment "album_artist=ALBUM ARTIST TEST"
input.mp3 synth 3 sine 20-20000
Will properly make a file that sounds like a sweeping sine wave, and the
ID3 title will be "Sweep". But the Album artist field is still blank. I've
tried several variations, to no avail:
band bandname albumartist album_artist group orchestra accompaniment
soloist performer leadperformer TPE2, which is the technical name in ID3
for the field I'm trying to give a value.
But none of them seem to work. Does anybody know the right "name" to use
for this value?

But none of them seem to work. Does anybody know the right "name" to use
for this value?
Issue in Adding Cursor Values to ArrayList
Issue in Adding Cursor Values to ArrayList
I am trying to query the default phone content provider's Phone Numbers
and storing the values thus obtained into an ArrayList ar = new
ArrayList(); Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur.getCount() > 0){
while (cur.getCount() > 0){
while(cur.moveToNext()){
//unique id
String id =
cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
//number corresponding to the id
String name =
cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
//lets check if this guy even has a number saved
if(Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)))
> 0){
//Query here
//Get the phone numbers!
Cursor pCur =
cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ "=?",
new String[]{id},null);
while(pCur.moveToNext()){
ar.add((pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))));
}
Log.d("String Report", ar.get(5));
pCur.close();
}
However this gives array out of bounds error at the Log.d method. For some
reason only one value is getting stored insidei.e. I only get ar.get(0) as
a valid output. What mistake am i making??

Android: how to measure time to come out of standby from power button press
I want to find how long it is the android devices come out of standby from
the user pressing the power button. In other words, to find out the
wake-up speed. I want to measure the time from app level programmatically.
Any ideas?

Style based on StaticResource previously defined is not found at runtime
Style based on StaticResource previously defined is not found at runtime
I'm using Telerik's RadControls for WPF with implicit styling. The
following style is defined in
Themes/Windows8/Telerik.Windows.Controls.RibbonView.xaml:
<Style TargetType="telerikRibbonView:RadRibbonView"
x:Key="RadRibbonViewStyle">
...
</Style>
My own styles and the Telerik default ones get merged like this:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary
Source="Windows8/Telerik.Windows.Controls.RibbonView.xaml" />
<ResourceDictionary Source="MyTheme/TelerikCustomizations.xaml" />
</ResourceDictionary.MergedDictionaries>
And in TelerikCustomizations.xaml I define the following (empty, for
testing purposes) style:
<Style x:Key="MyThemeRadRibbonViewStyle" TargetType="{x:Type
telerik:RadRibbonView}" BasedOn="{StaticResource
ResourceKey=RadRibbonViewStyle}" />
Which results in the following exception at runtime:
'Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an
exception.' Line number '4' and line position '42'. {"Cannot find resource
named 'RadRibbonViewStyle'. Resource names are case sensitive."}
Which led me to the following debugging statements in MyView.xaml.cs:
public ShellView()
{
var baseStyle = FindResource("RadRibbonViewStyle");
var inherited = FindResource("MyThemeRadRibbonViewStyle");
InitializeComponent();
}
Now the thing is: The exception is thrown on the second FindResource call.
With the exact same message. However the RadRibbonViewStyle is clearly
found in the first line of the constructor.
If it matters, the merged dictionary is actually merged in App.xaml a
second time.
I'm sure I'm missing something obvious, but I can't figure out what.

How to handle requireJs timeout error?
I'm writing a mobile hybrid app using require.js as my loading framework.
I have an issue with loading errors. What I'm trying to do is setup a
fallback solution when the device is offline and I can't download the
google maps API script that I need to display a map on the screen. All
that I get is
Uncaught Error: Load timeout for modules:

PyDev Interactive Python Shell in Eclipse
PyDev Interactive Python Shell in Eclipse
I've been using Wing IDE for python programming and I am trying to switch
to Eclipse, PyDev.
When I run my code in Wing IDE, after finishing the execution the console
goes right back to the interactive shell and I can continue on testing,
but I don't know how to do this in Eclipse. I'm not sure if I am
describing my problem properly so I'll use an example:
Let's say I had a simple source code that looked like this (e.g. test.py):
print("hello")
When I run this in Wing IDE by clicking that green arrow, the console
would look like this after execution:
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)]
Type "help", "copyright", "credits" or "license" for more information.
[evaluate untitled-1.py]
hello
>>>>
And I can keep doing whatever on the shell and it would know my code
(defined functions etc.). But when I do the same thing in Eclipse, the
console would simply look like this:
hello
and I have to click "Remove All Terminated Launches" button to go back to
the shell.
Can this be done in Eclipse?

Converting latitude and longitude to country in R: Error in .checkNumericCoerce2double(obj) : non-finite coordinates
Converting latitude and longitude to country in R: Error in
.checkNumericCoerce2double(obj) : non-finite coordinates
I am currently working with data (N of 271,848) in R that looks as follows:
Observation Longitude Latitude
1 116.38800 39.928902
2 53.000000 32.000000
3 NA NA
4 NA NA
And I am using the function code derived in the following post: Convert
latitude and longitude coordinates to country name in R
When I run the code to generate the country values, coords2country(points)
, I get the following error:
"Error in .checkNumericCoerce2double(obj) : non-finite coordinates"
My best guess is that it has something to do with the function not knowing
what to do with missing values (NA). When I ran the code on a subset of
observations (excluding NA's/missing values), it worked just fine. I
proceeded to modify the function slightly (see last line below), but that
still produced the error I am referring to above. Could somebody please
help me do the following:
Modify the code to properly handle NA's (or missing values).
coords2country = function(points)
{
countriesSP <- getMap(resolution='low')
#countriesSP <- getMap(resolution='high') #you could use high res map
from rworldxtra if you were concerned about detail
# convert our list of points to a SpatialPoints object
#pointsSP = SpatialPoints(points, proj4string=CRS("+proj=longlat
+datum=wgs84"))
#! andy modified to make the CRS the same as rworldmap
#pointsSP = SpatialPoints(points, proj4string=CRS("+proj=longlat
+ellps=WGS84 +datum=WGS84 +no_defs"))
# new changes in worldmap means you have to use this new CRS (bogdan):
pointsSP = SpatialPoints(points, proj4string=CRS(" +proj=longlat
+ellps=WGS84 +datum=WGS84 +no_defs +towgs84=0,0,0"))
# use 'over' to get indices of the Polygons object containing each point
indices = over(pointsSP, countriesSP)
# return the ADMIN names of each country
indices$ADMIN
#indices$ISO3 # returns the ISO3 code
#The line below is what I thought could resolve the problem.

php checking if file exists on an external domain always returns 403 or 404
php checking if file exists on an external domain always returns 403 or 404
ive been struggling with this for days now.
I have a subdomain mapped to a subfolder within the parent domain. i want
to use images images from its parent domain
i can link to the images fine by using a standard href in an image tag
linking to the file.
My problem is i need to runs some checks to see if the image exists and if
it does no to display an place holder image.
I have got all my code down onto a test page, the image tag displays the
image fine but any calls i do either using curl or get_headers returns 404
or 403 errors.
Both domains are on the same dedicated server under the same account and
they use the same credentials so its not a security issue (i checked with
my hosts)
SO why does the image display via html but i cant get the a 200 with php???
