Data mining is of course all right, but I don't think Raspcontrol has an API for external application, so there's no guarantee your app will work with future revisions of Raspcontrol.

@antiloquax: Sorry, I misunderstood you then. With your quote and the "You were right the first time", it seemed to me like that was what you were implying. Also what I said wasn't meant as criticism to the writer of the program or the MagPi, just as a tip to OP on a simple way of identify...

This might be a bit nit-picky, but VHDL isn't a programming language, it's hardware descriptive language. When you "compile" VHDL you don't get a program, you get a logical circuit.

The raspberry pi has pretty limited memory, so I'm not sure if RAM cache would be a good idea. With lighttpd you configure a directory for cached compressed files. That's how I've set up mine and that seems to work fine, though it's only for static files.

Actually, your skin is salty enough that just wetting your fingers will make them more conductive. Try this. Hold the two probes of an ohm meter and check the resistance. Then wet your finger and try it again. Big difference. I know, I've done exactly that. But the resulting resistance is still to ...

It's not the voltage, it's the current flow that matters. Well.. "Voltage hurts, but current kills". If you want to very effectively kill yourself in a rapid fashion, wet your hands and grab the terminals of a 6 or 12 volt vehicle battery - I guarantee that if your fingers don't spasm off...

This is a good thread. I got my Raspberry Pi a few days ago, and it's quite an exciting little thing. I've started thinking of how to build two custom circuits to wire to it (I've even drawn up some diagrams) - with more to come I am sure. I feel really good about this, because I've been wanting to ...

Hi. I "stick" when trying to extract the wheezy-raspbian files. My PC simply goes into "Not Responding mode and stalls. Simple as that. Any suggestions? That's very strange. Either the download got corrupted, in which case you can download it again, or there's a bug with the windows ...

You were right this time. The first time through the loop, it takes the starting point as (82, 125). From there it draws one black square (76 x 76 pixels). Then it draws 4 white squares (each 22 x 22 pixels). The "12"s and "42"s make it draw them within the black square. So the ...

After a quick glance at the dd documentation, I can't see it guaranteed it'll fail with an exit code of 1. I'd change the last to # If command has completed successfully, delete previous backups and exit if [ $result=0 ]; then rm -f /mnt/usb/backup_*.img; mv $ofile $ofilefinal; exit 0; # Else remove...

Probably a power problem, so check that first.

If not, SSH is enabled by default on the raspbian so unless you've changed that you can get access to the shell remotely. If you're on Windows download putty to connect over SSH.

so now my question is, how can i 'close circuit' with raspi pin ? Connect the two wires to drain and source on a MOSFET transistor, and connect the GPIO pin to gate and the GPIO ground to the drain. If it's an n-type MOSFET it'll not conduct when GPIO is high, but will conduct when GPIO is low. edi...

Actually, given enough investigation, you can tell exactly what code a compiler will produce. It is, after all, a totally deterministic computer program. Yes, you can disassemble the code the compiler produced, so in that sense you can "tell what it produced ". Most if not all c-compilers...

http://stackoverflow.com/questions/11334807/forwarding-accelerated-opengl-glx-via-ssh seems to be asking exactly the same question :) Note that the Raspi natively uses OpenGLES, whereas your network-connected desktop will be using OpenGL, so to do what you'd want optimally I guess you'd need the pr...

Try the trial version of this http://www.diskinternals.com/ntfs-recovery/ If it works, torrent or pay, depending. If you have to recover the files by themselves, rather than the partition, you should copy them to another harddrive.

Hmm, what do I do with my time? Well, I guess you could answer internet, torrented TV series, reading (mostly fantasy), gaming, programming, alcohol, drugs and studying. Pretty much in that order. I'm interested in psychology and medicine and read a bit about that on my spare time, and I study elect...

So what about this one?
Code: Select all
   d.rect(screen, black, (window[0], window[1], 76, 76) )

You can lookup what functions mean in the pygame reference.
This one draws a rectangle in black on surface 'screen'. The rectangle has coordinates (window[0], window[1]) and is 76x76 pixles big.

If it still boots XBMC you've either not deleted the partitions properly or you've mistakenly written the XBMC image. Probably the latter, as I don't really think you have to do the former. Try again and make doubly certain.

Insert the SD card (looks something like this, color, logo text and numbers may differ) you're using into the SD-card reader (the slot on your computer where it fits). Windows XP should recognize it pop up an alert or something. Note what letter it has (D:\, E:\, F:\ etc), but you can otherwise igno...

Got slightly better stats on most tests with an added -funroll-loops

Ive got it hooked up to the tv fine now, managed to find all the relevant cables. what i meant was the reason for getting the pi was because it would connect to my old CRT TV when no other computer will. Well, that's something. However what I wanted to do with it on my old tv was to be able to watc...

Most old CRT TVs have either a Composite Video or SCART plug, both of which the Raspberry support (the latter with a converter). Otherwise there are numerous things you could have your Pi do, everything from acting as a server in your home network to controlling a robot. It's perfect for learning to...

For the heartbeat solution I think I'd do something like this: Central Server: - Listen to UDP port for keep-alive - Listen to TCP port (with SSL) for association - Broadcast UPD every x seconds with updated randomly generated, time restricted string (TID) - on keep-alive, validate and update intern...

See this here: for window in windows: d.rect(screen, black, (window[0], window[1], 76, 76) ) d.rect(screen, white, (window[0] + 12, window[1] + 12, 22, 22) ) #tl d.rect(screen, white, (window[0] + 42, window[1] + 12, 22, 22) ) #tr d.rect(screen, white, (window[0] + 12, window[1] + 42, 22, 22) ) #bl...

In all likelihood assignment fails. This is because the length of argv is dependant on how many arguments are defined at the command line, and touple assignment (that's the "script, first, second, third = argv" line) requires that you have an equal number of items on both sides of the '='....
