My question is more like a theoretical.
Say you have an object, that represents the list of something (articles, pages, accounts etc.)
class ObjCollection
You have a class, that represents a specific item in collection:
class objItem
I have a problem thinking of a basic responsibilities of each object.
Which class is responsible for creating a new objItem?
Which class is responsible for deleting a objItem? Should it delete itself as a method?
I have a VM running Ubuntu Server 9.10 running a basic web server setup. Whenever I run an apt function it will pause for around 1 minute at 'Waiting for headers...'. It will eventually clear through and continue as normal but it is a bit of an annoyance.
Everything else on the server seems to run fine. Any ideas?

I know that this is jumping the gun slightly as it is early days but has anyone got any information on how we can build apps that take advantage of a basic local SQL database like you used(!) to in Windows CE/mobile 6.x? I can't find any info on the intertubes so maybe it hasn't been announced yet??
I am looking at integrating a C# application with a barcode scanner.
The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable.
Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry.
Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?
I am using PHP open source and I need the map of a country highlighting all the states in different colors. Once a particular state is hovered over, some info about the state needs to appear.

The Boost.Test documentation and examples don't really seem to contain any non-trivial examples and so far the two tutorials I've found here and here while helpful are both fairly basic.
I would like to have a master test suite for the entire project, while maintaining per module suites of unit tests and fixtures that can be run independently. I'll also be using a mock server to test various networking edge cases.
I'm on Ubuntu 8.04, but I'll take any example Linux or Windows since I'm writing my own makefiles anyways.

A custom windows form control named 'tweet' is in a dll. The custom control has couple of basic controls to display a tweet. I add this custom control to my main application. This custom control has a button named "retweet", when some user clicks this "retweet" button, i need to send some message to the main application. Unfortunately the this tweet control has no idea about this main application (both or in their own namespaces)
How can i send messages from this custom control to the main application?
Hi,
I'm searching a possibility to paint a graph in Java using AWT. My knowledge of Java is still basic, so this is mainly for getting used to AWT, even if it's already "old".

Hi All,
I have a JAR on the build path of a medium sized Java application and I would like to know where it's used. At the most basic level if someone could tell me how to 'Find References' for a Jar that would be great.
Whilst I'm looking at dependencies it would be great to find a tool that would map all of my package / external library usages and graph them. I used to have a free plug-in for eclipse that did just that but I haven't been able to rediscover it.
Thanks,
Gav
I've always been fascinated by microcontrollers and I'm planning to do a few hobby projects just to satisfy my inner geek :)
I'm looking for ideas and motivation, so what did you develop using a microcontroller?
If possible please state the microcontroller and/or development environment and an estimate on hardware costs beyond the basic equipment (if applicable).
I'm interested in both successful and failed projects and any problems you encountered.
While configuring my just installed Visual Studio 2010 Professional, I mistakenly opted for Visual Basic mode. I want to correct my selection and change it to C#. How can I do that?
Hi all,
I currently have a JAX-WS Web Service that receives some credentials in the HTTP header. These are used for BASIC authentication.
There is a filter that performs authentication by reading the HTTP headers and checking against the database.
Still, I need the username from within the Web Service in order to perform other service logic related stuff. Is there a way of accessing the HTTP headers from within the Web Service?
Thanks.
Anyone know of a good / small scheme interpreter in C++? Perferably something < 2000 LOC, with a simple garbage collectro (either compacting or mark & sweep), no need to support all of R5RS, just basics of if/lambda/set!/cons/car/cdr and some basic operations.
Thanks!
I have gone through with some of the sample examples of blackberry.
And in some classes I have found some variables are starting from _ like _address and some of them are ALLCAPS.
So, i guess it's bit different then the basic Java naming conventions.
So, can anybody let me know that is there any difference between Java and blackberry naming convention ?
Thanks in advance.

I'm looking at adding a user comment ticker to my iPhone/iPad polling app (Show of Hands). The comments would obviously need to be pulled from a central web source - either a database or perhaps even simple flat files. The ticker would also need to support basic controls (speed, pause, etc.) Can anyone that had tried doing something like this point me to your work and/or pass along any implemetation ideas?
Thanks!

Pretty basic programming question, I know PHP have a function for it, but does the iPhone OS have one?
I want to check if the current indexPath is a value in an array.
PHP Example:
<?php
$indexPath = 3;
$array = array("0", "1", "2", "3", "4");
if (in_array($indexPath, $array)) {
// Do something
}
?>
Does anybody know how to do the same thing inthe iPhone OS?
