Reflections on 2011: Open Source, Open Science and Open Chemistry

It has been so long since I uttered a word here, 2011 was certainly a busy year for me and I hope to ensure I dedicate more time telling people about what I am up to in 2012. In preparation for that I have spent some time moving my blog to some new hardware, in the cloud. I also got to the bottom of the poor performance of page loads, and things should be much snappier now. After all that I figured it was time for a cosmetic refresh, so after upgrading the Serendipity I selected a new and hopefully cleaner theme.

As an extra special treat I updated the photo to something a little more recent to - me emerging from my TARDIS with a mug of espresso in hand! Kitware grew a lot last year, so much so that we had to take space in a new building across the road. It was decided that our scientific computing team would move, along with the communications team. In the move I got my own office, with a view of the old office across the street.

VTK was accepted as a mentoring organization in the Google Summer of Code program. We were lucky enough to get two very talented and tenacious students who produced some great work over the summer. We also continued improving and extending Gerrit, and thanks to the Google Summer of Code I had the opportunity to attend both the Mentor Summit and the Git Together (held the day after). Not satisfied with two meetings in one trip I also attended a small portion of the Open Science Summit, and hope to be able to attend the whole thing if it happens again in 2012.

Speaking of Open Science, 2011 was a big year for the area both on a personal level and in the wider community. I talked about our work in open science at several conferences, and more specifically the work we have been doing in Open Chemistry. I wrote a Source article introducing the work that we have done in Open Chemistry since I joined Kitware, and we recently acquired the openchemistry.org domain and have begun populating it. We were also awarded a Phase II SBIR which gives us two years of funding to develop many of the applications and libraries that I mentioned in the article.

The Science Code Manifesto was conceived in 2011, and Michael Nielsen released his new book Reinventing Discovery. There was also Open Access Week which highlighted the need for open access to scientific journals and data. I was very pleased to be a coauthor on two open access articles in 2011, the Quixote project and the Blue Obelisk five years on. I was also honored to receive my own Blue Obelisk award in 2011 from Peter Murrary-Rust!

There is so much else, but I am out of time for now and this post is already very long. Google+ was released to the masses, you can see a little more of me there, and I have created an Open Chemistry page that I will try to keep updated over the coming year. I was invited to a workshop on Semantic Physical Science in Cambridge, England and so I will be starting my traveling very much earlier than usual - leaving next Thursday. Here is to a great new year, one in which I hope we as a community can make significant progress in opening science for the world, and creating a truly shared set of tools for all!

I hope that 2012 is the year more of us start sharing in meaningful ways.

One Year at Kitware...Already?!?

It is hard to believe, but I have been at Kitware for just over a year now. How are things going? I would say very well...I am very pleased I made the move, and that Bill Hoffman pushed me into applying after meeting him at the first Camp KDE. Kitware is growing fast, we are always on the lookout for new talent and I am already starting to feel like an old timer with all of the new employees joining.

I had my first ever annual review, which went well. We received word in September that my first SBIR proposal had been accepted, and we are working on getting the contract in place for that. So watch this space - a great collaboration coming up working on open source chemistry visualization, editing, database integration, and computational chemistry input file generation along with analysis of the outputs. I think this is a great opportunity to extend VTK, and Avogadro.

I took a very active role in our migration to Git, and I am pleased to say that it has been going well. I also more recently got Gerrit up and running, introducing tightly integrated code review to some of our open source projects at Kitware. I played a large role in setting up one of our most complex build systems to date for Titan, where it can build Qt, Boost and VTK (among other dependencies) using CMake's external project features. I have also had the opportunity to work with some of the Boost developers, and am helping with their build system work.

I have mostly concentrated on 2D rendering in VTK, using OpenGL. I replaced the existing 2D charts in VTK and ParaView with new charts using a new 2D rendering abstraction. So we now have a selection of chart types, with interactivity, that can be used on both client and server side. More recently I have been going even lower level, and working on FreeType font rendering in VTK, and seeing what I can do to improve the capabilities there.

There is lots of other stuff, some of it I have talked about here, and other bits I will when I find time. It has been a great first year, and looks like it is shaping up to be an even better second year. I feel very lucky to be getting paid to work on open source, open science and I get to work on some very interesting problems that help real scientists. Going forward I hope to introduce more scientists to open source, open data, open standards and collaboration platforms. I am very privileged to have worked with so many forward looking scientists over the last few years, and am a proud unmember of the Blue Obelisk.

I think Kitware is the perfect place for me to push forward open source in science, and am refreshed that I rarely need to push anyone here in that direction. I have been driven to learn a lot of new things in the past year, and it has been tough at times, but I have thoroughly enjoyed it. There are some really amazing projects coming up in the next year - so watch this space!

Back in England

marcus@cryos.net (Marcus D. Hanwell) — Tue, 31 Aug 2010 05:40:26 -0400

We are back in England after nearly two years away, we landed yesterday morning at London Heathrow. We flew with American Airlines this time (my first time with them), and I must say that I still prefer British Airways - they give you free drinks and I remember the staff being friendlier. The flight went well, and they got us in on time, immigration and baggage claim was all very simple, and so I was pleased the travel went well. William was a little angle on the flight, after letting him run around the airport for a few hours.

This is William's first time in England, so after getting the Underground to St Pancras Louise and I parted ways. She headed up to Sheffield with William, and I headed up to Chester to get my geek on. I will be spending the next couple of days talking with Noel, Tim and Chris about Open Babel development, CMake, Git, Gerrit and open source chemistry software i general. It should be a lot of fun, and while I have not had anywhere near the time I would like to work on open source projects in general, I think some of the things I am doing at Kitware might be useful.

Then Louise and I will be meeting up in London, staying with friends so that we can make our third trip to the US embassy to ask for another visa stamp. All of the forms have changed since we last went in 2008, and our visa type has changed. Hopefully that will all go smoothly, then we will visit another friend before returning up t'North together. I should finally make it up to Sheffield myself on Saturday, but plan on heading out on the Sunday. I have a week of meeting with chemists, physicists and materials scientists, mainly of the computational persuasion, to talk about cool stuff I am doing and what they are doing.

There will be a short intermission on the weekend for a friend's wedding, before continuing another week of talking to scientists. One of these visits will take me down to Cardiff, where Torchwood was filmed. So I am doubly excited by seeing the city where one of my favorite Doctor Who spinoffs was filmed, and meeting with more people to talk about quantum chemistry, electronic structure and visualization. I will be ending my time in England on this trip in Sheffield, meeting with old supervisors, friends and coworkers, talking about what I am doing now and how we might work together in the future.

I am also hoping to squeeze in a generous helping of real ale, some fish and chips, a few full English breakfasts and time to catch up with family and friends. Despite being back for quite a long time, and initially wondering what we would do, I find I don't have nearly enough time to meet with everyone I would like to and catch up with all of my old friends. We should try to make sure we come back more often! I think this post is long enough already - looking forward to getting out and about in England after my long absence. We will be looking around Chester later, before getting down to business.

Returning From Hibernation...

Wow, I just looked and I haven't written a thing since January! For those of you who might have been worried, or just wondered what I was up to...here is a quick run down. I am going to start with a little advice, combining starting a new family with moving from academia to industry and moving house it tough I have been really focused on work, home and one big conference, and kinda shut down otherwise.

I hope to remedy that in the coming months, and have started by doing some development for Avogadro and Open Babel. I also got Kalzium in KDE trunk ported to use the system Avogadro library, with some help from Pino Toscano. So KDE 4.5 will feature a Kalzium using the system installed Avogadro, this prompted a couple of bug fixes in Avogadro. So after that I tagged and released a much delayed Avogadro 1.0.1 with several bug fixes.

Way back in March Kitware was kind enough to send me out to the March ACS meeting, where I presented a talk on VTK, ParaView and its use in chemistry. I also gave a talk on Avogadro, and its use as a framework in chemistry visualization, which Geoff followed up with a talk on some applications of the Avogadro framework in his research.

The ACS conference deserves a full post of its own, but I feel like it has been so long I will just summarize a few of my thoughts. There were some other really interesting talks on visualization, and how it can be applied in chemistry. I got a general feeling that commercial software still has too much of a stranglehold, and hope to see that change as we develop powerful open source platforms that can be shared by all. There is a definite need for this in chemistry, and I am doing everything I can to seek some funding to further that cause, failing that I will continue to do what I can in my spare time.

I was honored to meet members of the Blue Obelisk for the first time. Saw some great talks about open science, open data, open standards and open access. I especially enjoyed meeting and seeing Peter Murray-Rust talk for the first time, I found that I share many of his ideals. I think we differ in some places, but life would be boring if that were not the case!

Our son, William, is nearly one year old already! He might be a big part of the reason why I have been inactive. The kinds of sleep deprivation torture you go through with children are indescribable He is thankfully sleeping quite well now, and even took his first two steps yesterday.

We had our first visitors in our new home - friends from Pittsburgh and Washington DC all came up for a weekend. I fired up our new BBQ, an enormous American style with offset fire box. Made some amazing ribs, and shared some of the home brew I made - a portable porter, and an English brown ale (first two batches). We are just getting ready for a trip to Pittsburgh, and then William's first birthday (planning a small party at our place).

Then there is work, lots of exciting things are happening there. I taught my first course at Kitware, going through ParaView plugins. The new CMake book came out (I am one of the contributors to the new edition), and the new VTK book came out at around the same time. Kitware is hiring, so please let me know if you are interested in applying. We have some really interesting projects to work on, most of my time is spent on something called Titan. Last Friday I also pumped the tyres up on my bike, and rode into work for "Bike to Work Day".

I have skipped loads of stuff, but already wrote more than I intended. I will see if I can be a little more disciplined and write more frequently. My current problem is finding time to fit everything in, but I have a new strategy I am working on in order to do better. Life after the big 30 is certainly different. I feel energized again, and hope to be writing about more fun and interesting stuff I am doing over the coming months.
