url rewrite with multiple param
I need to convert an URL, with some params like this:
/anytext/l1v5n3
to a normal URL with querystring:
/index.php?liv=1&id=5&lang=3
the params l, v, n could be in any order and the following value could be
numeric and can include special symbols (+,-, etc.)
Any help will be appreciated!

Sorted String List Array Based- Add Method
Sorted String List Array Based- Add Method
public void add(String item) throws ListException

// Throws an exception if the item connot be placed on the list
{
try
{
}
catch(Exception e)
{
throw new ListException("Add to List failed: " + e.toString());
}
}
i need help with the add method, how would go about this?

jQuery plugin's syntax is too strange
jQuery plugin's syntax is too strange
I have a little trouble about the meaning of syntax "(function( $ )" and
"(jQuery)" in the below code.
(function( $ ){
$.fn.myPlugin = function() {
// Do your awesome plugin stuff here
};})(jQuery);
Can you please explain what meaning of them ?
If I want to change phrase "(jQuery)" in the above code to "(abc)" then
how to do it and how to use it ?
Thanks for taking the time to answer my question.

I have a query always results to two rows. How can i flag the first row
equal 1 and the second is 0?
here is the code
$rows = array(
array('number' => 1),
array('number' => 2)
);
$i=1;
foreach($rows as $r) {
if($i == 1) {
$i = 1;
} else {
$i = 0;
}

What is the difference between a frame got from a video device and image loaded after saving the frame
What is the difference between a frame got from a video device and image
loaded after saving the frame
In matlab I am not getting what should I get after working on a frame. But
I get if i write that frame in a file and read it back and it works fine.
I = step(vidDevice); % Acquire single frame
imwrite(I,'tmp.jpg');
im=imread('tmp.jpg');
out=skin_detect(im);
But I get only the black image if I work directly on the frame.
I = step(vidDevice); % Acquire single frame
out=skin_detect(im);

I have a EJB with field
@Resource(lookup = "jdbc/sampleDS")
private DataSource ds;

I want to make the application easy portable across different Java EE

At the same time Glassfish doesn't like symbol ':'. How to achieve
portability? I tried to set attribute use-java-context="false" for data

Thanks in advance.

Prove/disprove statements regarding continuous functions.
Prove/disprove statements regarding continuous functions.
I found some old math tests from my school years and thought it might be
fun to see what I still remember. The answer is simply, not as much as I
hoped for. I'm having trouble proving/disproving these statements, not
sure where to go with it.
If f is a continuous function on the closed interval [a,b] then f([a,b] =
[f(a),f(b)] or f([a,b]) = [f(b),f(a)].
There exists a function f that maps ]0,1[ to R/Z+
Is there a continuous function that maps ]0,10] to R?
I'm pretty sure that when I get 2, 3 will follow closely, hopefully at least.

Why does $\frac{d}{d\theta} \theta\prod_{i=1}^nx_i = \sum_{i=1}^nx_i$
Why does $\frac{d}{d\theta} \theta\prod_{i=1}^nx_i = \sum_{i=1}^nx_i$
Is this just the product rule? I have this in my notes but I didn't think
anything of it and now I'm wondering how this happens?
Edit: Im working with maximum likelihood estimation and in my notes I have
that the likelihood funciton $=L(x;\theta)=\prod_{i=1}^nf(x;\theta)$ where
$x$ is the variable and $\theta$ is the parameter of a probability
distribution. To estimate I was told that we take the log of the
likelihood function e.i. $ln(L)$, then take it's derivative to estimate
the parameter. The function I'm working with is $f(x;\theta)=(\theta
+1)x^{\theta}$. So $$L(x;\theta)=\prod_{i=1}^n(\theta
+1)x_i^{\theta}=(\theta+1)^n\prod_{i=1}^nx_i^{\theta}$$ Now
$$ln(L(x;\theta))=n*ln(\theta+1)+\theta
ln\left(\prod_{i=1}^nx_i\right)$$Here's where I'm confused, I have in my
notes that $$\frac{dL}{d\theta}=\frac{n}{\theta+1}+\sum_{i=1}^nln(x_i)$$
Why does the product of $x_i$ become the summation of $x_i$?

Authenticate API-access against URL parameter instead of Authorization-header
Authenticate API-access against URL parameter instead of Authorization-header
I'm are using WSO2 API Manager for managing our public API's. I now have
the case where an external party wants to consume an API but only has the
ability to specificy a URL, no Authorization/OAuth headers can be added.
Is there a way to let the API Gateway authenticate against a URL-parameter
instead of the Authorization header?

VirtualBox Open Virtual Disk dialog on Mac is Hidden behind Storage Dialog
VirtualBox Open Virtual Disk dialog on Mac is Hidden behind Storage Dialog
I am trying to load an existing VMDK for VBox running on Mac Mountain Lion.
In the screenshot below we can see three relevant dialog boxes open:
The "parent" Storage dialog
The child "Please choose a virtual hard drive" dialog
Mostly hidden! The directory navigation/ Finder dialog In the screenshot
it is 90% obscured by the Storage dialog. We can barely see a bit of its
right side peeking through. That is a serious bug/problem.
The number 3 took me quite a while to realize what was happening: the
other dialogs naturally are not responding since the 3rd mostly hidden is
a modal dialog.
Anyone encountered this / determined a workaround?
I intended to put this on superuser. How can this be migrated to that sit?

matches to 'container1'?
Thank you for your time.

Get the `category_title` using javascript or from the category table using the same MySql query?
Get the `category_title` using javascript or from the category table using
the same MySql query?
In the items table I only save the category_id.
Is it better to get the category_title using javascript or from the
category table using the same MySql query?
All the categories are downloaded as a json file to the client when the
page is loaded. So the client has them all. (9KB)
Categories are around 700 items.
...
{id:1, title:"fruits"}
...
Using JS I would loop through categories until category.id ==
item.category_id and then return category.title.

JPanelMenu does not create the JPanelMenu-Menu class
JPanelMenu does not create the JPanelMenu-Menu class
The JpanelMenu will not create the additional class and I can't figure out
why.
I placed linked to the site with this HEAD
<script type="text/javascript"
src="http://jpanelmenu.com/js/lib/jquery.jpanelmenu.min.js"></script>
I then placed the script to enable the sidebar directly underneath it in
the HEAD
<script type="text/javascript">
$(document).ready(function () {
var jPM = $.jPanelMenu();
jPM.on();
});
</script>
I then placed the code for the nav within the HEADER
<a class="menu-trigger" href="#menu">Click Me</a>
<ul id="menu" style="display: none;">
<li><a href="/">Overview</a></li>
<li><a href="#usage">Usage</a></li>
<li><a href="#about">About</a></li>
</ul>
But then when I run the page inspector, the "click me" works and opens but
the sidebar is empty. It will NOT create the following class:
<ul id="jPanelMenu-menu" style="width: 250px; display: block; z-index:
1;">...</ul>
I think there may be something wrong within my CSS but I do not have any
elements created for JPanel Menu but I do have a left and right panel
within the body like so:
body {
height: 100%;
max-width: 100%;
min-width: 960px;
min-height: 600px;}
right-panel, .left-panel {
height: 100%;

.left-panel {
background: url('Images/side-bar-parchment.png') no-repeat fixed center;
background-size: cover;
position: absolute;
width: 170px;
z-index: 1;}

Why does inherting from object in Python, change they type of the __dict__
when not specifying a parent does not?
I have a simple piece of code that tries to give a convenience to file in
Python.
class File:
def __init__(this, *args):
this._file = file(*args)
def __del__(this):
this._file.close()
def createCallForwarder(method):
return lambda obj,*args: method(obj._file, *args)

for (k,v) in zip(_dict.keys(), _dict.values()):
if not (k.startswith('__') and k.endswith('__')):
if v.__class__.__name__ == 'method_descriptor':
File.__dict__[k] = createCallForwarder(v)
# get the repr method
File.__repr__ = createCallForwarder(dict_proxy['__repr__'])
If i change File to inherit from object, it does not let me assign the
methods.
Why is it different?

Is this related to the new 64 bit architecture of the iPhone 5S? Do I need

Sending file-path to already opened program
Sending file-path to already opened program
Can a C# program send a file to an already open program?
For example, if I have Photoshop running, a click would send a image path
to it as when I would drag an image from Windows Explorer to it... or
think about dragging txt file to notepad window.

posible set an inputmask ?

Getting failed expectations from GMock
Getting failed expectations from GMock
Currently, I am using GMock without GTest ( specifically, I'm using it
with mstest ). Is there any way to get a string of the failed expectations
?
IE:
EXPECT_CALL( mockObject, MethodWith3Params( 1, 2, 3 ) ).Times(1);
// Do does not call MethodWith3Params at all.
stuffDoer.Do( mockObject);
Assert::IsTrue( Mock::VerifyAndClearExpectations( &mockObject ), " "/*What
can I do here to say what expectation/s failed ?*/ );
I assume GMock is storing these strings ( or at least raw data that can be
used to deduce a message ) somewhere, since GTest is able to tell you when
an expectation isn't met.

Visual Studio Recovery Backup Location and Freezing
Visual Studio Recovery Backup Location and Freezing
We find that Visual Studio hangs frequently if our code is stored on a
network drive. Moving to to the local drive fixed this.
However, now we are using the Modeller, it saves recover information to
H:\Visual Studio 2012\Backup Files
and there seems no option to change that.
As a result, it frequently hangs with "Saving auto recovery information".
It does eventually complete, but it takes minutes to do so.
Our network drives work fine for other programs etc.
Has anyone else seen this and found a solution? Is the location a registry
setting?

When the Display() method called second time, surprisingly it hit the

IllegalStateException occurs when using Jackson @JsonDeserialize annotation
IllegalStateException occurs when using Jackson @JsonDeserialize annotation
I'm trying to use a custom deserializer in Jackson to deserialize some
json objects. However, when I try to have the ObjectMapper read the json,
the following exception occurs:
java.lang.IllegalStateException: AnnotationIntrospector returned Class
com.Geometry.GeometryDeserializer; expected Class<JsonDeserializer>
I'm somewhat at a loss of what to do here, since it seems like the
AnnotationIntrospector is complaining that my GeometryDeserializer is not
a subclass of JsonDeserializer, when it clearly is.
Here's where I create the Object Mapper:
public void deserializeJson(String json) {
ObjectMapper mapper = new ObjectMapper();
mapper.addMixInAnnotations(Feature.class, MixIn.class);
Feature feature = mapper.readValue(json, Feature.class);
}
...my Mix In class:
abstract class MixIn {
@JsonDeserialize(using=GeometryDeserializer.class)
abstract void setGeometry(Geometry geometry);
}
...and my deserializer:
public class GeometryDeserializer extends JsonDeserializer<Geometry> {
@Override
public Geometry deserialize(JsonParser jp, DeserializationContext dc)
throws IOException, JsonProcessingException {
//stuff happens
}
}
Any feedback/assistance would be greatly appriciated.
Thanks.

Development tool to structure the code?
Development tool to structure the code?
I've been searching for a development tool, which allows me to have a
diagram with all classes, public & private methods, attributes and
everything else which is relevant to them.
I could imagine something like this being pretty useful for planning out
your project + keeping track of it while developing, as I've had to
restart a project quite a few times in the past days because it just
turned into a mess of methods & attributes (perfectionist right here).
Are you aware of such a tool or do I have to spend time on making one?

Cancel handler.postdelayed from another activity in which it was not created
Cancel handler.postdelayed from another activity in which it was not created
Mind the typos, just a mock up.
class myActivity1 extends Activity
{
oncreate()
{
Handler myHandler = new Handler();
myHandler.postDelayed(myRunnable,1000)
}
onPause()
{
}
}
The handler does its job, and after 1 second the myRunnable runs. Assuming
I call another postDelayed inside my myRunnable, that restarts the
postDelayed for repetition.
In myActivity1 I am not using the removeCallbacks() function, thus the
myHandler will be running even if I leave the activity.
However, my question is, HOW CAN I CANCEL the myHandler from inside
another activity that I moved to ? (Assume my app has 15 activites, and I
do not know inside which one I am.)

Ruby 1.9.3 nil? undefined local variable or method. Is nil? broken?
Ruby 1.9.3 nil? undefined local variable or method. Is nil? broken?
I've been using var.nil? for a while, it's all over my code. Suddenly, I'm
getting undefined local variable or method for the variable with .nil?
after it.
What's going on? is .nil? broken? I even tried it on an IRB online to make
sure it wasn't something in my environment. I should be able to type:
me.nil?
and that should come back as true if the variable hasn't been defined,
that's the whole point, but I get undefined local variable or method me
for main:Object
Maybe I got nil? wrong and have to use something like:
defined?(me) == nil
and .nil? can only be used with an existing object? This was not the way I
understood it. The ruby docs even say this:
nil.nil? -> true
<anything_else>.nil? -> false
Going crazy here.

jquery range slider values which follows the handles?
jquery range slider values which follows the handles?
I'm playing with jquery range slider, I've managed to split two values in
different inputs. Now don't get mad at me, I'm still nooby about jquery
and I was wondering how to set up that each input follow its handle on
slider?
Like in this examples: http://egorkhmelev.github.io/jslider/
My code till now looks like this:
script:
$(function() {
$( ".slider-assets" ).slider({
range: true,
min: 100,
max: 500,
values: [ 200, 300 ],
slide: function( event, ui ) {
$( ".amount-assets1" ).val( ui.values[ 0 ] + "k €");
$( ".amount-assets2" ).val( ui.values[ 1 ] + "k €" );
}
});
$( ".amount-assets1" ).val($( ".slider-assets" ).slider( "values",
0 ) + "k €" );
$( ".amount-assets2" ).val($( ".slider-assets" ).slider( "values",
1 ) + "k €" );
});
html:
<input type="text" class="amount-assets1" />
<input type="text" class="amount-assets2" />
<div class="slider-assets"></div>
css:
.amount-assets1,.amount-assets2{
width: 48px;
}
and you can see and play with my jsfiddle here:
http://jsfiddle.net/dzorz/sJBLh/
The problem is that I don't know from where to start. Do I need another
one plugin that puts tooltip above handles or something else?
Any suggestion and solutions are welcome.
Thanks.

SublimeText 3, how to navigate between files in project
SublimeText 3, how to navigate between files in project
I'm new to SublimeText (migrated from TextMate) and it's awesome. But I'm
familiar with JetBrains IDE and I need functionality to quickly open a
file/class in a project. SublimeText provides cool features, like open
symbol anywhere, goto anything and so on, but I can't find anything to
open just files in a project. When I'm working on a big project – goto
anything and similar are not suit for me.
For example, I have a class named Data. When I'm trying to open that class
with 'goto anything/symbol in project' – I got a lot of variables and
methods in the list, because 'data' is pretty common word in programming.
So, I'm trying to achieve functionality to open only classes/files,
without searching inside of them (like JetBrains Navigate -> Class). Is
there any built-in functionality, or I need to write a custom plugin for
my needs?

For example, I have a class named Data. When I'm trying to open that class
with 'goto anything/symbol in project' – I got a lot of variables and
methods in the list, because 'data' is pretty common word in programming.
So, I'm trying to achieve functionality to open only classes/files,
without searching inside of them (like JetBrains Navigate -> Class). Is
there any built-in functionality, or I need to write a custom plugin for
my needs?
How do boolean operators work in 'if' conditions?
How do boolean operators work in 'if' conditions?
I am currently new to Python and am trying to run a few simple lines of
code. I cannot understand how Python is evaluating this syntax after the
if statement. Any explanations will be appreciated.
number = int(raw_input("Enter number : "))
if number == (1 or 2 or 3):
print "Match"
else:
print "No match"
Only the integer 1 yield a positive result and any other numbers including
2 and 3 go through the else branch. Can the conditions be stated as the
following only?:
if number == 1 or number == 2 or number == 3:
Thank you.

Way to short-circut propigation of checked exception in Junit
Way to short-circut propigation of checked exception in Junit
I just thought of something minor I would like to do and was curious if it
the ability to do it existed. It's purely a convenience syntactic-sugar
sort of thing, hardly mandatory to have, but a slight convenience I
thought may have been implemented at some point.
I have a method nestled 2-3 layers down in helper methods of a Junit test
case which throws a checked exception. I know for a fact that I want to
fail if this exception is ever thrown. However, if I just call Fail() I
lose the stack trace of the exception and the other conveniences that come
with allowing the exception to propagate
I know the 'standard' approach is to have the method throw the exception.
However, as I said, I'm buried a few methods deep already, and I suspect
this method will be called by many future helper methods. If I throw an
exception in this method I will have to constantly adding a throw clause
to all the methods that use this one method, directly or indirectly, which
could be quite a few methods. This is obviously doable, just a little
annoying; and, in theory at least, I could mask a situation where the
exception is thrown and I actually wanted to catch it if all my methods
already throw it.
Is there a way I can tell Junit to act as if the exception had propagated
up to the top level and fail, without having to have all my methods throw
it? So Junit reports a failure due to exception, with the stack trace and
all, immediately. Essentially I want a fail method that takes an
exception.
Does anything like this exist, or do I have to simply throw it?
ps. I know I could wrap it in a runtime exception and re-throw it, but I
don't really like that option either.

Boolean with loops to check an array
Boolean with loops to check an array
Write Java code for a loop that sets boolean variable isOrdered to true if

int i[] = { 1, 2, 3, 4, 5 };
int b = 0;
boolean isOrdered = false;
while (b < i.length) {
if (i[0] <= i[b]) {
isOrdered = true;

Making sure Checkboxes are checked on page reload jQuery
Making sure Checkboxes are checked on page reload jQuery
So I am having some strange functionality with this snippet of jQuery:
$(document).ready(function()
{
$('.pinToggles').attr('checked','checked');
})
This is the html:
<input type="checkbox" id="redCheck" name="pinSet" value="Red"
class="pinToggles" onclick="pinSetCheck(redSet)">Red
<input type="checkbox" id="yellowCheck" name="pinSet" value="Yellow"
class="pinToggles" onclick="pinSetCheck(yellowSet)">Yellow<br>
<input type="checkbox" id="greenCheck" name="pinSet" value="Green"
class="pinToggles" onclick="pinSetCheck(greenSet)">Green
<input type="checkbox" id="blueCheck" name="pinSet" value="Blue"
class="pinToggles"onclick="pinSetCheck(blueSet)">Blue<br>
What ends up happening is if I would uncheck some of the boxes and then
reload, it will only check the first unchecked box and then each refresh
after that it checks the following unchecked box. The functionality that I
want is on refresh is all of the checkboxes to be checked.
I was able to achieve this with javascript by using this:
document.getElementById('redCheck').checked = true;
document.getElementById('yellowCheck').checked = true;
document.getElementById('greenCheck').checked = true;
document.getElementById('blueCheck').checked = true;
But I think jQuery is the better way about doing this but unsure why it is
reacting the way it is right now.

AJAX async set to false block the page, otherwise can not get the value
AJAX async set to false block the page, otherwise can not get the value
I'm using an ajax request inside im.js so it will call my PHP server from
the js and get the feedback. However, I need to update an variable based
on the callback of the .ajax function like this:
var picture = "<img src='https://www.123.com/pictures/unknown.jpg'
width='30' />";
$.ajax({'type':'GET',
'async':false,'url':'https://www.123.com/site/getpic?username=' +
username,
'success':function(callback){
picture = "<img src='" + callback + "' width='30' />";
} //ajax success
}); //ajax
See that if i delete "async: false", the variable picture will not be
updated since ajax is async, and if I disable it like this, it blocks the
whole page from going on even I load the whole im.js async.
Please help: How can I update the variable, in the meantime, do not block
the page?
Thanks

Using image maps with text somehow (jquery?)
Using image maps with text somehow (jquery?)
First of all, I know image maps are kind of outdated, but they're not
deprecated yet, and neat enough! I'm upgrading an existing and really
cluttered image map, which is being used to show the work of different
labs around the world in an area of chemistry research, and really just
trying to tackle a coding/design problem for myself.
I'm wondering how I might go about coupling a rollover image fade (e.g.
for individual countries) with text (i.e. captions rather than a URL with
text tip). The map is rendered and setting coordinates is a simple enough
matter, but I need some way to produce links on rollover, such as for
[Researcher 1 | lab website],[Researcher 2 | lab website], etc. in
particular for when they reside in the same place on the map.
All I can seem to see being done to make these interactive from other
examples is alerts and single links for a region of an image map, but I'm
sure it could be more versatile and I'm wondering if anyone knows how I
could present text in this way?
Something that acts like this (shown all expanded) would be great source
I'm sorry I can't be more constructive but the code is too dense for me to
work out how that's done, and I get the feeling I might be missing some
basic solution...?

i need a text input area for a form to appear only if 'other' is selected

Well my question is pretty simple and straight forward. The html for the

use
<select id='combo'>
<option>Yes</option>
<option>No</option>
<option>other</option>
</select>
<input id='text1' style='display: none'/>
<input id='text2' style='display: none'/>

document.getElementById('combo').onchange = function() {
var display = this.selectedIndex == 2 ? "inline" : "none";
document.getElementById('text1').style.display = display;
document.getElementById('text2').style.display = display;
}
</script>
how do i go about applying this? if of course, this even works...

This code is working fine, but the problem is when i try to attach
nfc-card to my device, my activity hangs/freeze for at least 10/15 seconds
and then Dialog is shown as per my code. If i try to attach 5 to 6 cards
continuously one by one then its showing me all dialog after 10-15 seconds
at the same time. I don't know why my Activity is Hanging while reading

This code is working fine, but the problem is when i try to attach
nfc-card to my device, my activity hangs/freeze for at least 10/15 seconds
and then Dialog is shown as per my code. If i try to attach 5 to 6 cards
continuously one by one then its showing me all dialog after 10-15 seconds
at the same time. I don't know why my Activity is Hanging while reading
Tag from NFC Card.
Thanks in Advance
strace Darwin Streaming Server
strace Darwin Streaming Server
I am trying to find out how Darwin Streaming Server (DSS) cooperate with
the OS, and what are the most common system calls made by the DSS. I used
the following commands to attach strace to DSS processes:
ps auxw | grep /usr/local/sbin/DarwinStreaming | awk '{print"-p " $2}' |
xargs strace
However, as shown below, the output of strace is not informative:
I am just wondering if there is any way to figure out what I want.

Limited number of products displayed on portfolio page
Limited number of products displayed on portfolio page
On the portfolio page I want to a limited number of products. I have 300
products and that's too much to be all on one page.
I put this code for limited number of products (10 products per page)
'posts_per_page' => 10
And I put this code for insert page switching (in this case 30 page)
<!-- Pagination -->
<?php if(function_exists('pagination')){ pagination(); }else{
paginate_links(); } ?>
<!-- Pagination End -->
And in fact both codes work. Number of shown products is limited to 10
products. At the bottom of the page I got the option to switch to one of
the 30 pages.
But whatever number page I click, I always opened the first 10 the
products of.

Get elements that are not inside of an element that has a known class

</div>
<input type="text" data-required="true"/>

I want to get all elements that have data-required attribute from .test

second input would be returned.
I tried:
$(".test [data-required]:not('.class1')")
but it returns the both input because :not doesn't select the parent
elements.
Is this possible with one jQuery selector?

I've been given a class - GoodPetStoreClient - that makes use of another
class - NoisyPetStore - in order to create a list of objects - Cat, Dog
and Cow - which implement an interface - MakesSound - and have been asked
to modify NoisyPetStore to ensure that GoodPetStoreClient will compile
properly. I've been trying to work out what I'm missing, but without luck
so far, and would appreciate some more experienced insight.
Thanks!
Here's the code public class GoodPetStoreClient {

NoisyPetStore petStore = new NoisyPetStore();
petStore.addPet(new Cat());

I've been given a class - GoodPetStoreClient - that makes use of another
class - NoisyPetStore - in order to create a list of objects - Cat, Dog
and Cow - which implement an interface - MakesSound - and have been asked
to modify NoisyPetStore to ensure that GoodPetStoreClient will compile
properly. I've been trying to work out what I'm missing, but without luck
so far, and would appreciate some more experienced insight.

All entries in registry are gone
I am working on wine to install some windows software in my linux.
Following some guidelines on the web, I made some changes in registry. I
suppose it will save the changes on its own, since there is no a "save"

found everything was gone! What might be the reason for this? Can I
download and import a new registry?

Rails Engines, mountable apps etc, effect of failure of one
Rails Engines, mountable apps etc, effect of failure of one
I assume that if you mount an app in a main rails or use a rails engine.
If any of the sub-apps fail/crash than that means the main app and all the
sub-app fail/crash.
Does anyone know this for sure? I am wondering if I am building a system
if I should separate my architecture into multiple standalone application
and instances or build Engine/mountable apps instead of a larger app. The
worry is what would happen if part of the app ecosystem goes don't how
does it effect the rest of the applications.

Avoiding full postback when using OnClientDateSelectionChanged on a control
Avoiding full postback when using OnClientDateSelectionChanged on a control
I am using ASP.NET c# 4.0
I am using AJAX.
I am using ajax calendar extender which after selecting a date fills a
text box with a chosen date. I wanted to execute some server side code
when the date changes so I put this in :
OnClientDateSelectionChanged="function
ddd(){__doPostBack('DateTextBox','') ;}" into the extender control.
Unfortunately, the whole page gets posted back. If i put this control in
an Update control it tells me that it is already in an update control. If
I include the textbox within the update panel i get 2 of these text boxes
on my web page after selecting a date. Does anyone know how to inform the
server that the date selected from this ajax control has changed without a
full post back please?
thanks

Design Pattern to track partial results of a complex process
Design Pattern to track partial results of a complex process
I'm facing a programming problem that I don't know how to solve in a
object oriented and flexible way. I have in mind some bad solutions, but
I'm searching for a good one. I develop in Java, so I prefer Java ideas,
but any object oriented idea is welcome.
I've been searching for ideas, design patterns, or some algorithm that can
help me, but I don't know which terminology or name give to my problem, so
I couldn't find any clue.
Problem:
Summary:
I need to track partial results of a process that makes different changes
to a collection of entities. I need this to report to the user, the detail
of each calculation "step" in a table report. And also I need to persist
this collection in a database.
Detail:
The software I maintain has an entity similar to this one: public class
Salary { private Date date; private BigDecimal amount; }
That is grouped in a Collection, like this:
List<Salary> teamSalaries;
This set of entities can be modified by a set of "tasks" depending on some
rules:
Apply a certain tax (from a set of differents taxes)
Calculate a Future value for the money amount (More Info)
Discount an amount of money to keep below a maximum
etc...
For example:
public void processTeamSalaries(List<Salary> teamSalaries) {
applyTax(teamSalaries, Taxes.TAX_TYPE_1);
(...)
getFutureValue(teamSalaries, someFutureDate);
(...)
restrictToAMaximum(teamSalaries, Maximum.MARRIED_MAXIMUM);
(...)
applyTax(teamSalaries, TAXES.TAX_TYPE_3);
(...)
}
public void applyTax(List<Salary> teamSalaries, Tax taxToApply) {
for(Salary aSalary : teamSalaries) {
aSalary.setAmount(calculateAmountWithTax(aSalary.getAmount(),
taxToApply);
}
}
(...)
What I need is to process this collection of salaries, making changes to
the amount of money but preserving all the intermediate "states" of the
money amount, to show it to the user in a table with columns like these:
Date | Original Amount | Amount after tax 1 | Future Amount | Amount after
restriction | Amount after tax 2
My Ideas:
Add an attribute for each "partial result" on the class Salary
public class Salary {
(...)
private BigDecimal originalAmount;
private BigDecimal amountAfterFirstTax;
private BigDecimal amountAfterMaximumRestriction;
(...)
}
Problems:
The "steps" aren't rigid, maybe tomorrow one "step" changes, a new one
appears, or the "meaning" of some step changes. In that case I will need
to refactor the code too much.
Some "steps" can be repeated, so, how can I tell to the "method" in which
attribute have to "set" the result of the calculation?
Add a HashMap to the Salary class where I can put the partial results, and
pass to the "step" method the "key" where it have to put the partial
result
public class Salary {
(...)
HashMap<String, BigDecimal> partialResults;
(...)
}
Problems:
In some place I need to populate the HashMap to a JPA entity to save it on
my Database
If another developer changes the name of the key (for whatever reason)
maybe the "populating" of the attributes gets broken
Final Note: There are other similar situations with other "similar"
entities in my application, so it would be great if we can find a general
solution for this :D

Thread.sleep() skips to last method in Java/Android
Thread.sleep() skips to last method in Java/Android
While there must be a better tactic of completing a countdown I have set
up in my app, it seemed clear to me that using Thread.sleep(1000) between
every digit would work. It did not and I still do not have any other
solution. When I run the app, the countdown goes from 5, straight to 1 in
1 second.
This is my code:
bBegin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
bBegin.setText("5");
try{
Thread.sleep(1000);
}catch(InterruptedException ie){
}
bBegin.setText("4");
try{
Thread.sleep(1000);
}catch(InterruptedException ie){
}
bBegin.setText("3");
try{
Thread.sleep(1000);
}catch(InterruptedException ie){
}
bBegin.setText("2");
try{
Thread.sleep(1000);
}catch(InterruptedException ie){
}
bBegin.setText("1");
try{
Thread.sleep(1000);
}catch(InterruptedException ie){
}
Thanks, I hope this problems helps other noobs like me (and no worries, I
did check the site for a previous solution)

Return just the results from %SYS.ProcessQuery using $SYSTEM.SQL.Shell() in Intersystems Caché on a Unix server
Return just the results from %SYS.ProcessQuery using $SYSTEM.SQL.Shell()
in Intersystems Caché on a Unix server
Background
Hi,
I work with a Unix-based application that uses an Intersystems Caché
database. Since I'm not that familiar with Caché, it wasn't until recently
that I found out I could type...
$ cache
...to enter the database. From here, I found out I could access a number
of things like the %FREECNT report, the ^DATABASE routine (to view/modify
the size and other properties of the database), and $SYSTEM.SQL.Shell().
Since I found the $SYSTEM.SQL.Shell(), I've found a number of things I can
use it for to obtain info about the database, specifically running
processes using the %SYS.ProcessQuery table.
I'm able to run queries successfully - for example:
USER>ZN "%SYS"
%SYS>D $SYSTEM.SQL.Shell()
SQL Command Line Shell #Comment - Sql Shell Intro text
--------------------------------
Enter q to quit, ? for help.
%SYS>Select PID As Process_ID, State As Process_Status From %SYS.ProcessQuery
The above query will return results in this format:
Process_ID Process_State
--------------------------------
528352 READ
2943582 HANG
707023 RUN
3 Rows(s) Affected
--------------------------------
Question
Considering the background identified above, I'm looking for a way to
return just the results without the "SQL Command Line Shell" intro text,
the column names, or the row count footer. When I write a .ksh script in
Unix to connect to Caché and run a query, like above, I return the
results, along with the following text that I don't want included:
SQL Command Line Shell
--------------------------------
Enter q to quit, ? for help.
Process_ID Process_State
--------------------------------
3 Rows(s) Affected
--------------------------------
Additional Info
I realize I could use Unix commands to filter out some of the text using
awk and sed, but I'm looking for something a little easier/cleaner way
that might be built-in. Maybe something that has a silent or
no_column_names flag, like the example in this LINK.
My end game is to have a script run that will obtain info from a query,
then use that info to make changes to the database when certain thresholds
are met. Ultimately, I want to schedule the script to run at regular
intervals, so I need all the processing to occur on the server instead of
creating a separate Client app that binds to the database.

Accessing json value where attribute has ":"
Accessing json value where attribute has ":"
I am using a REST service and it returns json formatted like this:

How can I create a class at server side corresponding to this type of json
for parsing? I am using c#.
EDIT
This is the code I am using
JavaScriptSerializer serializer = new JavaScriptSerializer();
JsonClass result= serializer.Deserialize<JsonClass>(jsonresult);
JsonClass is the class I have created with the fields corresponding to the
attributes in the jsonresult. And the problem is, I can't create a
property with name ea:productionId as it contains :.

When I create a phonegap folder structure via the CLI (3.0), how do I open
this in Eclipse?
When I choose project [New] - [Android project from existing code], the
assets are taken from the platforms/android folder. But I need to change
the html and js of the top folder (www). These are the files that are
being used when I build the project to other platforms (via CLI or

WKHTMLTOPDF Installation error on Ubuntu
WKHTMLTOPDF Installation error on Ubuntu
We require features like header, footer, table of contents and cover page
of pdf, which we want to generate from html/css. We tried WKHTML on
windows and it worked like a charm, when moving to our server, we
installed WKHTML on our ubuntu server, installation process was successful
but it had only limited features, it was able to generate pdf from HTML
but all features mentioned (i-e header, footer , table of content and
cover page) wasn't working. Following is the error which it was producing.
"The switch -t, is not support using unpatched qt, and will be ignored.
Error: This version of wkhtmltopdf is build against an unpatched version
of QT, and does not support more then one input document."
We followed many tutorials and installed it with QT patched, one of the
tutorial is here (https://code.google.com/p/wkhtmltopdf/wiki/compilation)
. We are not sure if we skipped something or did something wrong, it is
installed and few of features has started to work but not all. we are able
to generate header and footer but cover page and table of content are
still not working. which we really need.

time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(1378182603));
## yields '2013-09-03 10:00:03'
How can I achieve the same in R?

Intelligently Detect Duplicate Content Using PHP
Intelligently Detect Duplicate Content Using PHP
I have built a web scraper that takes a website or RSS feed, parses said
contents of the feed and or website, extracts all of the appropriate
information and then saves it into a database. This is a personal
experiment to see if I can build an intelligent and anonymous web scraper
with no real purpose just to see how advanced I can go and then I will be
open sourcing the code for others to learn from.
The problem is I am scraping at present 3 news websites. When it comes to
breaking news, there is a high chance all 3 websites (especially if it's a
big story) will all be writing their own interpretations of the news, but
ultimately it's the same news.
I have been trying to come up with a solution that can detect as best as
it can when an article being pulled in has already been spoken about and
imported from another news website and perhaps the link is associated with
the story (other sites also wrote about this: link1, link2).
Is there a tried and tested way of detecting if one or more pieces of
content are effectively the same? I've written some pseudo-code, but
unfortunately I'm not a very smart developer to take it and make it
something that works.
Here is my thinking:
A link to a website is parsed
Generic words are stripped out and keywords left in (company names,
countries, etc)
The remaining words are then counted and a score is calculated
That's where my thinking hits a roadblock. How do I efficiently create a
snapshot of a page and then compare it to pre-existing content in my
database I've already imported? This is how I think it needs to be done.
Perhaps I am over-thinking this and I merely need to check if articles
have similar titles?

Get the continent/country or location of user in php?
Get the continent/country or location of user in php?
Is possible to get the continent from where the user it is accessing a
site? I do know i can get the language of the browser like this:::
<?php
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
switch ($lang){
case "fr":
//echo "PAGE FR";
include("index_fr.php");//include check session FR
break;
case "it":
//echo "PAGE IT";
include("index_it.php");
break;
case "en":
//echo "PAGE EN";
include("index_en.php");
break;
default:
//echo "PAGE EN - Setting Default";
include("index_en.php");//include EN in all other cases of
different lang detection
break;
}
?>
REF
Also i do know there is something php function call ->
geoip_continent_code_by_name which if a pass a string with the host name
it will return me:
Code Continent name
AF Africa
AN Antarctica
AS Asia
EU Europe
NA North america
OC Oceania
SA South america
But this only returns me the host name, so is there any way to get the
same result but for the user who is accessing the site? or is even
possible to do?
