Who I am

  • Linux user since 2002
  • Ubuntu and Debian user since 2007 (x86, amd64, armel)
  • Canonical ARM developer from 2010-11 (working together with the Ubuntu ARM team)
  • Linaro Developer Platform Tech Lead (since 2011)
  • Contributions to many OSS over the past few years (OE, Mamona, Maemo, Linux, Gentoo, Ubuntu, etc)
  • Member of the Ubuntu Bug Control and Ubuntu Universe Contributors groups

Working with OSS development since 2003, and doing general distro development since 2006. While Gentoo user I contributed with package and kernel fixes. From 2008-10 worked helping created an OpenEmbedded based distro called Mamona. Since 2010 I've being working at Canonical, first at the Ubuntu on ARM team (2010-11), and later as the technical leader of the Linaro Developer Platform team, working always with Ubuntu, improving the status and support for the ARM platforms we support.

Large experience with SW development, mainly using Python and C. Being a generalist, worked from Kernel to X11, also doing a lot of distro development.

My Ubuntu story

After some long years using Gentoo (also Debian, but mostly at the University), I decided to move to a package oriented distro, and by 2007 Ubuntu seemed the best option around (it was getting quite famous, and most friends were using it already). After using it at most of my X86 servers, I started using it with my EeePC for desktop purposes, helping debugging and fixing the RT2860 wireless driver.

During 2010 I joined Canonical to work as an ARM developer, being part of the old Ubuntu on ARM team. Since mid-2011 I was then assigned to Linaro to lead the Developer Platform team, which was responsible for delivering Ubuntu based builds for all the ARM boards supported by Linaro (also continuing to push improvements to the official ARM port at Ubuntu).

As a generalist, I helped pushing packages and modifications to Ubuntu since the bootloader to the graphical stack used by Ubuntu (e.g. Nux/Compiz/Unity for OpenGL ES2.0).

FTBFS with new Mesa (that was uploaded at the same time the new glmark2 release was also uploaded)

Kernel fixes:

  • 3.5.0-12.12: installing omapdrm specific headers for external drivers
  • 3.5.0-208.14: installing omapdrm specific headers for external drivers

Areas of work

  • Ubuntu Kernel fixes
  • X-Loader/U-Boot maintenance
  • GLES support at the archive (including OpenGL ES2.0 based drivers for supported vendor)
  • Usual image testing and bugfixing
  • FTBFS for armhf
  • Image customization at Linaro (Linaro Evaluation Builds)

Worked with normal bugfixing, Feature Freeze Exception, MIR and also with the SRU process.

As a result of my work I've being mostly working with the Ubuntu on ARM team, with the following core developers:

  • Oliver Grawert
  • Michael Casadevall
  • Jani Monoses
  • Adam Conrad

Also worked with the Kernel Team improving the ARM support when possible.

Besides work directly happening at Ubuntu, I also try to help improving the communication between Linaro and Ubuntu, supporting discussions at UDS/Connect and also participating at the weekly release meetings.

Things I could do better

Spending more time helping and fixing the FTBFS for ARM (usually the arch with most FTBFS).

Plans for the future

General

Continue working on improving the ARM experience on Ubuntu, by helping fixing the images and developing new features. Also plan to help maintaining the Pandaboard support, by providing kernel fixes and new releases of the PVR driver (besides making sure the UI stack also works properly with it).

What I like least in Ubuntu

Usually the time it takes for a SRU to hit the final user. It's also normal for kernel SRUs to take a few weeks to hit the archive.

Ricardo is a very prolific and capable packager and engineer in general (as the list above clearly shows). Although I haven't been involved in sponsoring any of Ricardo's packages, I have been relying on a number of them for my linaro work (mesa-utils-extra, clutter, pvr-omap4) and his work has always been superb. Beyond his technical skills, he is also a great person to work with: when I found some some issues in the pvr-omap4 packaging that were blocking my work, Ricardo was very responsive and open to ideas and discussion and produced an excellent solution to the problem. I believe he is a valuable addition to the Ubuntu community.

Kate Stewart

Ricardo has an excellent understanding of how all the pieces fit together to get features and fixes into the stable and development releases. He's very detail oriented and responsive, and he's one of the folk I rely on to know the right bits to pull together when things aren't working in the ARM space. I have a very high respect for the quality of his work, his willingness to proactively communicate, and his ability to keep things in perspective.

Endorsements

Jani Monoses

General feedback

I trust Ricardo to create great package uploads. I have sponsored some of his recent work related to ARM boot loaders, miscellaneous FTBFS fixes concerning ARM GLES, and OMAP graphics driver packages. He always does extensive testing before requesting sponsoring so I never had to ask for any change nor did any of the uploads need further fixing after in the archive. He works well with upstreams, picking relevant fixes and attributing them correctly in the changelogs. He understands well the packages he works on.

Specific Experiences of working together

He'd ping me on IRC or via email (or ask for any sponsor on IRC and I'd offer) with a short description of why an upload is needed, and links to debdiff/bzr branch and link to tested src (and sometimes deb) packages to try out. They were all short experiences, as there was not much to discuss. He only needs sponsoring, not mentoring.

Areas of Improvement

UDD, the keeping in sync of packages and bzr branches is not the easiest thing. The only occasion I remember needing to do a bit more work when sponsoring Ricardo is fixing up UNRELEASED/natty in the changelog and setting a proper bzr release tag. But I suspect my lack of experience (and discomfort) with UDD also played a significant role in this taking more time than it should have.

Oliver Grawert

Working with Ricardo is a pleasure, i sponsored plenty of uploads for him which were in a good enough quality that nobody had to touch them. Technically his packaging work is outstanding and at a level where he definitely should get the ability to upload his changes himself.

Even though Ricardo works on ARM stuff on a day to day basis, he additionally puts spare time and after hour work into helping the community and giving support in areas that don't necessarily touch his work area.

Ricardo is a big addition to our ARM community and a person that will give you reliable help in the #ubuntu-arm channel if you have any issue.

Since working in the ARM world usually means that you have to touch packages all across the archive so his granted upload rights should cover this.

When Ricardo joined the ARM team he immediately took over rootstock which is a tool to enable the wider community to roll rootfses for unsupported hardware. He improved the existing code massively and is very responsive on bugs, if a community person has problems building images you can rely on him providing or merging a fix in nearly no time. The same goes for his other areas of work (bootloaders, graphics drivers on ARM, the GLES stack) as well.

Adam Conrad

Ricardo is on my short list of people I really enjoy sponsoring uploads/patches for. He has both sets of skills that I think are quite valuable to a core-dev:

  1. A broad knowledge of Ubuntu/Debian, and how all the pieces fit together, and how not to break A by fixing B.
  2. An understanding of what he doesn't understand, leading to asking questions, or just plain not touching things he doesn't think he's qualified to break.

I have no hesitation whatsoever with endorsing Ricardo's application and have, in fact, been bugging him to do this for months. I've often joked that I don't want him to apply because then the quality of submissions I get to sponsor will go down (due to no longer having his in my queue), which I suspect is a pretty good reason to give him upload privs. Wink ;)
