GDB version 6.8 was released just a few days ago. I’m happy to have made my small contribution to it, mostly with development of decimal floating point debugging support. From the NEWS file: “GDB now supports debugging C and C++ programs which use the Decimal Floating Point extension. In addition, the PowerPC target now has [...]

gdb’s backtrace command implemented in python
Posted in english, tagged community, development, gdb, linkedin, linux, open source, planet ltc, python on Monday, March 24, 2008 | 1 Comment »
I’ve been working on Python bindings for exposing GDB’s frame_info, the internal structure it uses to keep track of the frame stack in the debuggee (or inferior, in GDB parlance). I got just enough working to be able to implement an equivalent of GDB’s backtrace command entirely in Python. The difference is that my version [...]
new linker for Linux and others ELF OSes
Posted in english, tagged community, development, linkedin, linux, open source, planet ltc on Saturday, March 22, 2008 | Leave a Comment »
Cool, Ian Taylor (who wrote the current linker used in Linux) just announced that gold, the new linker that he has been writing, was just released. It targets only ELF systems, so I believe its design is much simplified and streamlined by this. I find it interesting that he chose to implement it in C++. [...]
python scripting in gdb!
Posted in english, tagged community, development, gdb, linkedin, linux, open source, planet ltc on Friday, March 14, 2008 | 7 Comments »
It seems the planets are finally aligning to get Python scripting support in GDB! Vladimir published his changes last month, Tromey improved on them, and I joined the bandwagon. The work is being done in a git repo hosted by gitorious. More details here. This looks very promising. Update – 2008/03/15: Sorry, I was a [...]
autoconf tip
Posted in english, tagged autoconf, autotools, development, hint on Thursday, March 13, 2008 | Leave a Comment »
I always dreaded having to do modifications in Makefile.in (e.g., adding a new file to the compilation) because then I’d have to nuke the build directory (you do build your project outside of the source tree, right? ) and run configure again for the Makefile to be generated and then rebuild everything again. Well, of [...]
danger! bug in digikam 0.9.3 can cause image loss
Posted in english, tagged bug, digikam, fotos, hint, kde, linux, open source, photos on Thursday, February 28, 2008 | Leave a Comment »
I was downloading pics from my camera this weekend (strictly speaking, from its SD card) and found out about a nasty bug: digikam will fail to download an image for no good reason, and overwrite good images when you tell it to try again! I immediately opened a bug report, let’s how this progresses. A [...]
neverball and other simple games in Linux
Posted in english, tagged games, hint, linux, open source on Saturday, February 23, 2008 | Leave a Comment »
I’m not really a computer games person. For some reason, I started playing less and less games since I was about 16 years old. After a while, the only game I still played was NetHack (the ASCII or ncurses versions, I don’t like the X ones). And Koules too, for a while. Anyway, I started [...]
portable ogg vorbis player
Posted in english, tagged hint, mp3, music, ogg, player, review, vorbis on Thursday, February 14, 2008 | 1 Comment »
It took me some time to actually own a portable digital music player (mp3 player), because I didn’t want an mp3 player, really. I was searching for an ogg vorbis player and it takes some effort to find one, especially in Brazil where the sound format is virtually unheard of. I was gladly surprised when [...]
KDE vs XFCE in terms of memory usage
Posted in english, tagged hint, kde, linux, xfce on Sunday, January 6, 2008 | 2 Comments »
For the moment I have to cope with a low-memory machine at home, so I decided to switch it from KDE to XFCE. But is it really worth it, in terms of memory savings? I decided to measure… First of all, I’m not trying to do rigorous analysis here but just do some estimates to [...]

Olha a bicicleta que tinha pra alugar no Parque Ibirapuera, em São Paulo: Parece até que foi feito no Photoshop! The bike above was available for rental at a park in São Paulo…Even looks like it was made in Photoshop.
