One of the most common patterns I’ve run into while working on PiBox has been threads that process inbound data via a queue. The pattern is simple enough. Initialize a thread to acquire data When data arrives, put it into a data structure Place the data structure on a queue […]

Thread Management with Mutexes and Semaphores

It took some work, but I finally have SGX fully integrated into the build and have BeagleBox booting into an X session that can run opengl apps. I ran the SGX demos and they all seem to run fine. A couple showed frame rates betweeen 45 and 52 frames per […]

BeagleBox: SGX fully integrated

Mon September 03, 2012 in BeagleBox / Hardware / omapfb / Open Source / X11 tagged BeagleBox / SGX

So I've integrated TI's SGX package into the BeagleBox build. What this does is to run the SGX package's Makefile-based build which in turn installs a bunch of stuff from the archive into another directory. This directory will then contain a bunch of files which need to be installed again, […]

BeagleBox: SGX “install” script sucks

My media server died this past week. Actually, just the hard drive. It was running Fedora 14 and needed to be updated anyway. This server hooks into my Sony Bravia TV via HDMI using an nVidia GeForce 9800GT. After installing Fedora 16 to a new drive, I loaded kmod-nvidia and […]

I've managed to build and boot Buildroot 2011.02 using the 2.6.32 Arago kernel and Crosstool-NG 1.8.2 with GCC 4.4.3 and uClibc 0.9.30.2. The build works just as well as the older Buildroot 2010.11 I had been using, but there is a problem with where fonts are being installed. For some […]

The media server hooked to my big Sony Bravia in the living room has been running MythTV for awhile now, though my wife has never been a big fan of its UI. In fact, she hasn't asked to use it. Ever. She prefers the ease of use of Web based […]

Work is finally getting under way on the 2nd edition of the Artist's Guide to GIMP Effects. I've updated the text of sections 1, 2 and 3 to match the current state of GIMP development on the 2.8 release. I shipped those off tonight for review by the editor – […]

I’m back to working on BeagleBox again after a long pause. The holidays were the first delay, but now I’m down to working only weekends on BeagleBox because my weekday nights are taken up with working on the 2nd edition of my last GIMP book (promised to the publisher, No […]

BeagleBox: no joy with Xorg yet

Sun January 30, 2011 in BeagleBox / Hardware / Linux / Open Source / Software Development / X11 (updated 4825 days ago)

I’m wondering if the recent Sourceforge attack has anything to do with RPMFusion’s download1 host not responding. I did some upgrades at work this week and had problems with it and yesterday I upgraded a media client at home and found Mauriat Miranda’s links to configure RPMFusion timing out. I […]

I’ve opened a little shop on CafePress called Go Geek Early. I’ve made a few small designs and I’m working on some more. This is just a way to generate a little extra cash to help, for example, get my kid a beater car while she’s up at college. It’s […]

I’ve added copies of the final image from each of the last four tutorials I did for Linux Format’s GIMP column. These are the last of the series, as Linux Format is putting the coumn to sleep for now. They said it might come back later. For now, however, I’ll […]

I was reading Slashdot this morning and ran across a link to a story about the Internet instability last week caused by minor bugs in two routers that propagated across the planet in something like 30 seconds. While the story itself is interesting (a good read if you’re into how […]
