• Sliding window algorithm for activiting recognition MATLAB

  - by csc

  I want to write a sliding window algorithm for use in activity recognition. The training data is <1xN so I'm thinking I just need to take (say window_size=3) the window_size of data and train that. I also later want to use this algorithm on a matrix . I'm new to matlab so i need any advice/directions on how to implement this correctly.

• What's the primary use of Windows Event Viewer?

  - by james.ingham

  Hi all, Just wondering what everybody's opinion is on the Windows Admin tool Event Viewer? I'm writing a WCF application at the moment and have started logging errors to the windows event viewer when I handle them. I then started thinking, should I be logging more than just errors, such as when a user has logged in or out or would you go further logging even more activity? Or is this a tool that's mainly used for testing without using the debugger? Any input appreciated:-)

• Android: GPS location updates when the cellphone is in sleep?

  - by wei

  I need to update the location through GPS in the background even when the phone is in sleep. I am thinking to use AlarmManager to broadcast an Intent and then a receiver will call requestLocationUpdates() on LocationManager. But I am not sure whether it's guaranteed that the GPS location will be updated when the phone is in sleep and an intent will be broadcasted if I registered a PendingIntent when call requestLocationUpdates()? thanks,

• How to implement Template Inheritance (like Django?) in PHP5

  - by anonymous coward

  Is there an existing good example, or how should one approach creating a basic Template system (thinking MVC) that supports "Template Inheritance" in PHP5? For an example of what I define as Template Inheritance, refer to the Django (a Python framework for web development) Templates documentation: http://docs.djangoproject.com/en/dev/topics/templates/#id1 I especially like the idea of PHP itself being the "template language", though it's not necessarily a requirement. If listing existing solutions that implement "Template Inheritance", please try to form answers as individual systems, for the benefit of 'popular vote'.

• Database Structure for vBulletin Message Board

I am brave.

• Javascript Sandbox

  - by Louis

  I want to have developers write some custom apps for a site in Javascript but I want to sandbox it so they can't do anything naughty like redirect the user, set the body display to none etc etc. I have a namespace in Javascript where all the functions they'll ever need exist in there so I was thinking to create a sandbox would be a matter of: with(Namespace) { //App code goes here where they can only access Namespace.* } How is easy is it to get around this and what other methods can be done? Would rather not have to moderate every submitted app.

• Popularity of RDF format vs RSS

  - by frankadelic

  If you are building an RSS parser, how important is it to build support for RDF? Are any new feeds being published in only RDF? My thinking was that RSS 2.0 (and Atom) have replaced RDF. I actually had not heard of RDF until a client pointed out some feeds that are RDF-only.

• How is the iPad going to be classified - as a mobile platform or a desktop platform?

  - by Tony Eichelberger

  I sometimes use the following site to look at browser and OS trends http://gs.statcounter.com/. It got me thinking about how the iPad is going to be classified, as a mobile platform or a desktop platform, or is it going to spark a new category. Since it runs iPhone OS, it could be considered a mobile device, but I have a hard time with that because of the screen size. What should iPad be classified as: Mobile, Desktop, or Other (Try to come up with a good name for Other)?

• Reasons to start a new project in COBOL

  - by luvieere

  Are there any feasible reasons to start a new project in COBOL? What benefits of this language one would find convincing enough to start a new project in it?

• What's the fastest way using lsof to find a single open file?

  - by jjclarkson

  I'm trying to test a single file if it is open using lsof. Is there a faster way than this? $result = exec('lsof | grep filename | wc -l'); if($result > 0) { //file is open } I'm thinking their must be a way to just test for one file if you know the filename. All I really need is a true or false.

• Use only alpha channel of texture in OpenGL?

  - by Chris

  Hey, I'm trying to draw a constant color to the framebuffer and blend it using the alpha channel from an RGBA texture. I've been looking at glBlendFunc and glBlendColor, but can't seem to figure out a way to ignore the RGB values from the texture. I'm thinking I'll have to pull out the alpha values myself and make a second texture with GL_ALPHA. Is there a better way to do this? Thanks!

• UITableViewCell checkmark change on select

  - by user333673

  Am I correct in thinking that to change the checkmark for "on" to "off", I must change the CellAccessoryType between none and checkmark on the didSelectRowAtIndexPath? Because I have done this but I have noticed the behaviour is not perfectly identical to like the checkmark cells on the auto lock settings on the iphone. Or is there some other way checkmarks are meant to be handled?

  How do I create an rss feed in ASP.Net? Is there anything built in to support it? If not, what third-party tools are available? I'm thinking webforms, not MVC, though I suppose since this isn't a traditional page the difference may be minimal.

• How to simply this logic/code?

  - by Tattat

  I want to write an apps that accepts user command. The user command is used in this format: command -parameter For example, the app can have "Copy", "Paste", "Delete" command I am thinking the program should work like this : public static void main(String args[]){ if(args[0].equalsIgnoreCase("COPY")){ //handle the copy command } else if(args[0].equalsIgnoreCase("PASTE")){ //handle the copy command }/** code skipped **/ } So, it works, but I think it will become more and more complex when I have more command in my program, also, it is different to read. Any ideas to simply the logic?
