I know you know. But well, just in case you forgot..
Since 2004, I've been actively involved in
development of Launchpad, and in
2005 I became application manager for the project, together with Steve Alexander. These days
I lead a team of over 30 people at Canonical working on building a
platform for the future of open source development and
In 2003, I somehow managed an MSc degree from USP São Carlos, where I
wrangled out my dissertation on defining a Process Model for Free
Software Projects. My MSc project is described in two long documents (in portuguese). I
graduated in Computer Engineering from UFSCar in 1997, though most of that
time evaporated into swimming pools and bike trails.
A couple of years ago (just as I had decided I wanted nothing to do
with computers) I discovered Free Software and Unix, and I've been
working on both ever since then. I've contributed to dozens of
free software projects, and I am currently an active developer for
Bugzilla, PyGTK, ZODB, Kiwi and IndexedCatalog.
I've worked with Web development (who hasn't?) and Usability,
additionally, in the past years.
I am a partner at Async Open
Source, a company that provides development and consulting
services focused on on Free Software. I helped found Async in early
When I'm not pretending to be a software engineering manager I
engage in outdoor sports, travelling, language and vain philosophy. I've raced mountain bikes
for a couple of years now, and from 1999 to 2003 I raced a number of
national-level adventure races, including the multi-day EMA 2000 and

What he's been up to
(Read older diary entries)
CUPS & double-sided printing?
- We have a decade-old Laserjet 1320 that is great for double-sided
printing. That is, until recently -- perhaps even as recently as we
moved our workstations to Trusty. What happened?
- The best hint I found was at
trying to set the default options for the printer. When I enabled
double-sided printing, CUPS warned me there is a Duplexer Installed
option -- which was off. Fixed!
Updated Server BIOS for out S5520HC
USB drives and burn-in
- I'm replacing the server USB backup drives and looking for good
alternatives. I've picked a few and am trying to burn them in before
making the commitment (as previous drives I was trying to use ended up
dying on me mid-flight). Burn-in for me is badblocks for a few days and
some SMART self-testing.
- One of the drives I got was a Seagate, and it annoyed me that there
were a lot of errors in the two first SMART values listed by
smartmontools as I did a badblocks on it:
1 Raw_Read_Error_Rate 0x000f 100 100 006 Pre-fail Always - 236840
7 Seek_Error_Rate 0x000f 100 253 030 Pre-fail Always - 204379
I say it annoyed me, but then I read this:
- So the lower side of the number is just a counter. And math shows they have zero errors. Yay!
- And if you have a USB drive that has self-tests being aborted by the
host, check to see if it's not sleeping mid-test. At least that is what
says; I'm trying it.
- Daft Google syncml limitations:
- Saved my ass with DD-WRT passwords today not being synced between web
and ssh: [www.dd-wrt.com]
- Quora just taught me:
Answer from Susan Ng
I learned this in 1st grade - it's a REALLY easy and simple way to learn
your nine times table. Or to teach someone else to learn!
1) Look at your (or someone else's) hands
2) Say you want to find 9x7. Put down your 7th finger
3) Count the number of fingers to the left of your 7. This is your tens
digit. Count the number of fingers to your right. This is your ones
- What a trick:
- Typing the em-dash:
- Getting .bash_profile sourced:
- Just ran into:
Juju and LXC
- Debugging session as to why I can't get the local provider to give me
new machines in Juju. This is probably a regression in 220.127.116.11, but I
still don't know yet.
- One thing which is interesting is that the log for machine-0 is
actually where a lot of the container traffic appears. machine-0 is the
bootstrap node, and in the local provider, it's what houses all the
- root@chorus:/etc/default# apt-get install lxc/precise-backports
- Escape the console?
- lxc-ls is busted?
HP Virtual Rooms
- The trick to getting [rooms.hp.com] to work is to know that the
plugin and application they provide are 32-bit. That's not something
which is obvious unless you actually read the page carefully, and the
failure mode is completely unobvious (the installer runs, the plugin is
there, the test page looks like it works but no virtual room ever opens,
with a URL flashing quickly before loading back into the test page). There
is a trick which you can use to test manually and see what is wrong:
kiko@limpinho:~$ cd .hpvirtualrooms
bash: ./hpvirtualrooms: No such file or directory
kiko@limpinho:~/.hpvirtualrooms$ file hpvirtualrooms
hpvirtualrooms: ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15
Aha! Okay. So I need some 32-bit libraries..
- First step, I need
sudo apt-get install libc6-i386
- That lets me see via ldd the situation. And it's pretty bad: I need a
total of 44 libraries pulled in as dependencies from this core set:
libsm6:i386 libpng12:i386 libfreetype6:i386 libxi6:i386
libx11-6:i386 libasound2:i386 libstdc++6:i386 libfontconfig1:i386
libxrender1:i386 libxrandr2:i386 libglib2.0-0:i386 libxfixes3:i386
- But once that's done, it seems to work. I need to put a bit more
effort into validating it in the office, but I at least now know how to
do it. And best of all, it doesn't seem to need Java!
