Day: November 26, 2006

Gah! I used to do this for a living?

As part of my vacation recovery, I decided to submit a patch to make GPSBabel understand CoPilot version 4 files. I wrote the module for understanding CoPilot files back in 2002, but it only understood version 3. I decided to make it check the version number in the header and do the right thing for any version.

Now back in 2002, I cargo culted the existing GPSPilot code, and what I was doing wasn’t hugely different from what I already had there. But I haven’t written C code for a living since … (checking my resume) … 1994. Since that time, I’ve been coding in C++, Java, and perl. And I haven’t even done C++ since 2002. Grovelling along a “pointer to data” to try and extract some binary data into a format I can use is something that these days I’d do using pack/unpack in perl. C just seems so damn primitive now – almost like something that belongs in the last millenium. And it does. I was so impressed with it when I first started using it. But that was a lifetime ago.

QA versus development

On a mailing list somewhere I was musing about why I, as a developer, always find myself annoyed at QA. And that’s not good, because QA and development are partners in making sure that what we develop comes to the customer as good as we can make it. But the problem is that development never has time to properly document what we’re doing to QA, and QA only communicates to development in the form of bug reports.

As far as I can tell, there are only N types of bug reports:

  1. annoying because you already knew about what they are reporting.
  2. annoying because you thought you were done that bit and now you have to go back to it.
  3. annoying because you know that part works and now you’ll have to drop everything to go show them how they are using it wrong.
  4. annoying because you thought that part works and now you’ll have to drop everything to have them show you how they are using it right.
  5. annoying because their bug report doesn’t give you enough detail.
  6. annoying because it goes into excruciating detail when you could tell what is wrong from the first sentence.
  7. annoying because it goes into excruciating detail about stuff you already knew, but glosses over the bit that tells you if it’s a known bug or something new.
  8. annoying because they are describing something that’s working the way it’s documented to work.
  9. annoying because they are describing something that’s working the way you want it to work, but you haven’t had time to document that behaviour yet.
  10. annoying because it’s the same bug they already logged a week ago.
  11. annoying because it’s so poorly written that you can’t tell if it’s the same problem as the one they already logged a week ago.
  12. annoying because you thought you’d fixed that last week but it’s obvious from the report that you missed something.
  13. annoying because you thought you’d fixed that last week and it’s not obvious from the report if they’re testing the new code or not.

But what it all comes down to is that QA is annoying because they’re a constant reminder that you’re not as good as you wish you were. I don’t want to be “only human”, I want to be perfect.

Getting there.

I’ve gotten a few steps closer to moving everything that was on my Linode virtual private server over to my colocation box. Basically, the only thing left there is the hardest one to move, and that’s the navaid.com waypoint generator. Part of the problem is that the new site has FCGI instead of FastCGI, and part of the problem is that I’m going to be converting from MySQL to PostgreSQL, and of course the version of MySQL in Debian Sarge doesn’t have the “compatibility” option in mysqldump. Oh well, I’ll get there.

Today I moved my Mailman mailing lists over. Since the versions of Mailman and Postfix were the same on both places, it was a pretty simple matter of copying the files over. The hard part was managing the cut-over so that no mail got lost. That meant getting everything set up on the new site, using rsync to make sure the files were absolutely up to date, checking out the permissions, and once I’d tested the setup using forced fake DNS entries, cutting over the real DNS entry. I think it’s all working right.

Next up, I’m considering moving my Gallery installation over. I’ve also got to get out and install a new hard disk that was given to me.

Tell me, is it a bit weird that on one of my few days off from a stressful software development project I spend the whole day futzing around with computers?
