Back home / debugging

I’m now back home after a couple of weeks of lots of traveling. I first was 4 days in London, visiting my sister, then was 5 days at home, sick with a flu most of the family got while in London, then last weekend to beautiful Salamanca for a conference at the University. Back home on Sunday, still a bit sick, and on Monday flied back to Stansted for a 2 days visit to Michael, for some debugging and bug fixing fun.

So, in this 1.5 days of fun action at Michael’s, I’ve learnt a few useful bits:

  • Some useful tools, like LD_DEBUG, pmap, fuser, c++filt
  • Technique: this was the best part of it, since Michael is what we could call a superhacker, so watching him debugging stuff to look for a problem’s cause is very helpful (even though you can’t read everything he writes, since he does it so quickly :-) ), and he has some nice habits in his technique that should help me a lot, now that I’ve learnt them, in my bug hunting work.
  • I had an idea about writing scripts using lots of these tools for our users to use them for reporting super-useful bug reports, so will be writing a little bit about that as soon as I start looking at it.

While visiting Michael and his wonderful wife and daughters, I had the opportunity to meet my sister and family on Tuesday for dinner, since they were visiting Cambridge that day, where they will be moving soon, so I will have the opportunity to visit both my family and Michael (for more debugging and technique learning fun) more often.
