Nishanth' tech rambles

After a long while of staying off linux-omap, been watching it rather closely recently.. here are some interesting stuff I saw this month: Power Management: Operating points and general PM strategy for handling for various silicons here Silicon Feature support for OMAP3 here New silicon support: OMAP35xx and 36xx support being introduced. Discussion on memory and cache issue here ETM, ETM support here few new PMIC - 6030 and 5031 hints of wl1251 support getting upstream IO_ADDRESS is dead use io_remap like the rest of the world spring cleaning of omap850/730 series and of course a bunch of stuff I have missed posting here such as move to 2.6.32-rc4 by Tony and Kevin, both pushing out patches to mainline etc.....

High time I "ported" my posts from facebook back here.. so here it goes Some really bad code stories: shared by rob clark - how bad can some code go?? http://thedailywtf.com/Articles/The-Shenanigans-Handler.aspx Aint this cool: http://arstechnica.com/web/news/2009/09/horrifically-bad-software-demos-become-performance-art.ars Techno Curios: Tired of fullspeed, highspeed, lowspeed?? how about superspeed?? tired of acronymns already?? http://www.pcworld.com/article/172757/wheres_usb_30.html Search for my cheap oscilloscope goes on: http://www.micahcarrick.com/06-06-2006/pc-sound-card-oscilloscope-linux.html http://www.fpga4fun.com/digitalscope.html Hacks 'nd bytes: PS3 back with Hulu.. http://www.ypass.net/blog/2009/06/got-a-ps3-want-hulu-back-easy-enough/

drawtime This is kinda a cool app that runs on ubuntu to draw timing diagrams as follows: Example(from the drawtime website): CS1 = 1, OE = 1, ADDR = X, DATA = Z. CS1 = 0, OE = 0, ADDR = "". OE -tOE> DATA = ""; CS1 -tCS1> DATA; ADDR -tACC> DATA. OE = 1, CS1 = 1, ADDR = X. CS1 -tH> DATA = Z; OE -tH> DATA; ADDR -tH> DATA. and you can now generate all those cool waveforms without having to worry about did you get the lines right etc.. more such cool stuff here
