Hi,
I am writing and opengl based iphone app and would like to allow a user to translate around a view based on the direction that they move two fingers on the screen. For one finger I know I could just calculate the vector from the start position to the current position of the users finger and then find the unit vector of this to get just the direction, but I don't know how I would do this for two fingers, I don't think adding the components of the vectors and calculating the average would work so I'm pretty much stuck...
thanks in advance
What language is smart so that it could understand 'variable a = 0 , 20, ..., 300' ? so you could esely create arrays with it giving step start var last var (or, better no last variable (a la infinit array)) and not only for numbers (but even complex numbers...)
Hello guys, I just wanna know if it is possible to pause a playing SWF file in adobe flex?

I am using MongoDB for storage but the initial db size is around 50MB (even with --smallfiles given to the server at startup).
How can I start off with a much smaller db size (1MB max)?
My friend has convinced me to start learning some C++, so my question is simple: where can I find some good tutorials for it?
But please don't link me to the usual dry boring tutorials that only tells you the function syntax, I need more thorough explanations. I get sidetracked very easily, and I need tutorials that are more on a human level, that I'll not only learn from, but enjoy reading as well.
So I'd appreciate any links that would help :)
We are interested in the communities opinions on commercial MVC controls ie Telerik, Syncfusion. Which is fast, easy to use, stability, documentation, support and all that good stuff.
We are about to start our second MVC project and are currently doing research into improving functionality and speed of development to 'standard' MVC.
Any of your thoughts are much appreciated...
I can't figure this out and I thought that someone might run through the same thing.
I have XCode 3.2.3 (Pre Release with OS 4 beta) and I started to create my application, after the final touches and everything worked ok, I changed the Simulator - 4.0 to Simulator - 3.1.3 (latest iPhone OS) and I could never start my app again :-(

Hey everyone, I want to start using Scheme and I have two questions. First, would you recommend using an interpreter or a compiler for Scheme and why? Second, which interpreter or compiler for Scheme would you recommend and why? Thanks!
I've just created a new project but the structure is incorrect so I'd like to start again. It is it possible to delete a project from within IntelliJ or do I just have to close it and delete the relevant .iml/.idea files?

I have to solve the following: I have an Activity which's android:screenOrientation="portrait". Even though, when the device is rotated to landscape while this Activity is visible, I have to start another one, and, when the device is rotated back to portrait, I have to finish() the activity in landscape. I tried to perform this with a BroadcastReceiver, but this special activity doesn't receive any broadcasts because of the android:screenOrientation="portrait". Any help is well appreciated.
Thanks.
I'm looking for a regular expression that can extract the href from this:
<a href="/tr/blog.php?post=3593&user=930">
There are hundreds of links on the page so I need to extract only those that contain
/tr/blog.php
So in the end I should be left with a list of links that start in /tr/blog
Thanks for any help. It's really puzzling me.
I am a bit puzzled by this strange behavior on CentOs 5.4 when starting Tomcat 6.0 as a service
I've added a script at /etc/init.d/tomcat that can start/stop/restart Apache Tomcat 6.0 with user 'tomcat', and registered it as service. The problem with the service is that I am getting a 'Neither the JAVA_HOME nor the JRE_HOME environment variable is defined'. But when type 'sudo -u tomcat echo $JAVA_HOME' I get '/usr/java/jdk1.5.0_22' which is correct since I am using that JDK. What can I do about this?
Hi,
I have a question about how to store the assembly language in memory,when I compile the C-code in assembly, and run by "step", I can see the address of each instruction, but is there a way to change the start address of the code in the memory?
Second question is, can I break the assembly code into two?
I am curious about how the machine store the assembly code.
BTW, I am working on a MACBOOK Pro, duo core.
Thank you.

To help support and anyone who may use one of my applications I tend to log a few things during the application startup.
Currently I log:
Start Time
App Name
App Author
App Version
App Classpath
Current working directory
Java vendor
Java version
Max heap size
Taking into consideration this application may be used / supported by a whole host of people can anyone think of any other vital details which we / others should log for good practice?
I am injecting HttpContextBase into a caching class. HttpContextBase is registered as PerWebRequest. I interact with the caching class on each web request and this works fine, but I also need to initialise the cache at application start.
I understand that PerWebRequest does not work in Application_Start though:

What is the best way to resolve this in my situation?
Every time I start a hard problem and if can not figure out the exact solution or can not get started, I get into this never ending discussion with myself, as below:
That problem
solving/mathematics/algorithms skills
are gifted (not that you can learn
by practicing, by practice, you only
master the kind of problems that you
already have solved before)
only those who went to good schools can do it, as they learned it early.
What are your thoughts, can one achieve awesomeness in problem solving/algorithms just by hard work or you need to have that extra-gene in you?
Guys I study C++ for a second year. Till now I was doing only console app but I think it's a time to start programming in Windows. There are few alternatives and Qt is one of them but I'm also drawn towards pure Windows API - for more power of course. What would you suggest?
What is the general meaning and where did it start to have variables with leading or trailing underscores?
ex: _varName and varName_
I have always thought a leading underscore indicated the variable was a pointer but I don't know where I got this idea. Recently I have seen these naming conventions used in Java which makes that reasoning completely wrong.
