I’m here in Westford over the weekend with other members of the Fedora Design Team for their Fedora activity day. I traveled up to chilly Boston on Thursday midday, so I could assist by transporting people from the airport to our hotel in Westford.
On Friday, we convened in the Red Hat office in Westford. As is usual for my Westford visits, I pretty much spent the day running from place to place taking care of things unrelated to the Design team, but which needed to be done in my role as a manager. Fortunately most of the day was spent by the team figuring out policy and processes. I don’t feel like my input was needed there, or even appropriate since I’m not a frequent contributor to design tasks — as much as I love the team! So it all worked out for the best, I think.
Today, though, I was able to contribute. One of the major task areas was to do issue triage and fix up the team’s Trac instance. That was something I was (somewhat) qualified to do. I helped the team go through all the pending tickets, closing stale tickets (no response, unclear goals, redundant, etc.).
Then, using the categories developed by the team on Friday, I helped update the parameters on the Trac instance to match. I also set up a bunch of reports on Trac to match relevant agenda items for the reboot of the Design team meetings. This way, they can call up a set of reports to follow up on tickets methodically.
I even learned some good SQL-fu thanks to my buddy Langdon White. I finally got a start shedding my misunderstanding of joins, so I can do more complicated queries. One of the results was this report, which tells the team when an issue reporter is not responsive to questions, in line with the processes the team worked up on Friday.
People tried hard to make sure the FAD was remote accessible, so if you couldn’t be here, you could still monitor or participate. It was difficult to keep some of the facilities working. For instance, this afternoon I discovered that someone had bounced us from our own room on OpenTokRTC. That made it, well, rather difficult for us to broadcast there. I hope remote attendees will understand the difficulties and be confident we tried to make this a decent remote event.
Tonight I’ll probably think about some additional reports, and then do a little personal work. Tomorrow will be some more work sprints until I start chauffeuring people to the airport after lunch. I was happy to be part of the group and to help the participants have an effective FAD.
At this point I was finally exhausted. I headed back to the hotel early to do a little more reading and writing. I met up with some of the Anaconda team for a late dinner. Then I packed so I’d be ready in the morning to catch my flights back to the USA.
The Flock conference was excellent this year. It was nice getting back into the swing of community things. I enjoyed meeting up with everyone I saw. If I didn’t get a chance to see and talk with you personally, I’m still glad you were there. I hope you had a great time at Flock in Prague. Let’s do it again next year in the USA!
Here’s a summary of today’s activity where I participated or attended:
If you’ve been reading the Planet Fedora feed lately, you probably know that we’re coming up to time for Flock 2014, a major Fedora conference for Fedora users and contributors from North America and EMEA (Europe/Middle East/Africa). Along with most of the Fedora Engineering team, I’m headed to Prague, Czech Republic for the event.
First, we’ll spend a couple days in the Red Hat Czech office in Brno. We are meeting with a number of colleagues from the office, both to brief them on work we’re doing, and to hear about their current projects and plans. This should help us have a more productive Flock as well.
It’s possible team members may be a little harder to instantaneously reach on Monday and Tuesday while we crunch on these meetups in Brno. At Flock, obviously things will be busy as well. But seeing many community members in one place will probably be quite helpful in getting things done. We’ll do our best as always to stay on top of community requests and input throughout.
Flock 2014 should be an exciting and fascinating conference, and I’m very much looking forward to it. I’m hoping to use the conference to jumpstart my knowledge on Docker, OStree, and some of the other awesome technologies going on in Fedora. And of course I’ll be thrilled to see old and new friends from around the community.
I’m writing this from Schiphol Airport in Amsterdam, getting ready for my next leg of travel to Prague. I’ll be catching a bus to Brno there to meet up with the team. On Tuesday night we’ll get back to Prague. We have a team event that night — so we’ll see everyone bright and early on Wednesday morning at the conference!
I’m up in Westford at the Red Hat offices for some departmental events this week. It’s always fun traveling to the office and seeing coworkers and friends I normally only hear (or see online in text form). It does, however, eat mightily into my ability to be online in Fedora and interacting with friends, teammates, and contributors there. I’ll be up here through Thursday afternoon and then flying back home. So if you reach out to me but I’m a little slow to answer you in IRC or email, my apologies, and I’ll catch up as soon as I can!
DevConf.cz day 1, Friday.
Friday was the first day of sessions at DevConf.cz, the biggest and best Czech open source event by developers, for developers. The event was packed, with over 900 attendees even before the weekend started!
First up at 9:00 sharp was Tim Burke’s keynote about how Red Hat sees the IT market, specifically Linux and open source technologies. He covered how the various pieces of cloud, applications, storage, and platform fit together. It was pretty breakneck because there wasn’t a lot of time until the sessions started, but well observed and thoughtful. It’s clear the technologies built by people at this conference will set the pace for the future. The market has placed its bets on Linux and open source, and now it’s on us to deliver!
Langdon White followed with a story of startups. He covered how the tradeoffs between agility, stability, and maintenance can be mitigated by Software Collections. Software Collections allow IT groups to add stacks on their platform without affecting the deployment itself, while meeting more needs for developers and users.
Alex Larsson did a talk to a packed room (the biggest at the conference, no less!) on Docker, the open source container engine rapidly sweeping the community with its speed and flexibility. Fedora is rapidly developing a great grasp of Docker, and you can already install it on all supported Fedora releases. Obviously Red Hat has taken a huge interest in Docker too, so it’s no surprise the talk was SRO.
I went to Colin Walters’ session on OStree, a new way of distributing Linux operating systems. I found this session incredibly compelling, and I hope we look seriously at OStree in Fedora because of the problems it solves. There are clearly some issues that still need to be worked out, but Colin is up front about them, and he’s motivated and eager to collaborate with people to solve them. He’s truly one of the good guys of free software and I enjoyed this talk a lot.
I also attended Ondrej Hudlicky’s session on software usability, which was entertaining but also thought-provoking. A lot of what goes into making good software we either take for granted or completely miss. It’s so easy for software to suck when you don’t start by thinking about what the user is trying to do, and making that easy. Although the slides were quite dense, Ondrej did a great job explaining the concepts and why they were important.
I also attended sessions on DNF’s SAT solver, caught a bit on static analysis that went way over my head, and saw Richard Hughes’ session on GNOME Software. DevConf.cz is so packed with content, it’s impossible to see more than about half of what you’d like. There’s so much more content for Java folks, low-level network and hardware hackers, and kernel jockeys that it makes your head spin!
In the evening I went with a bunch of folks to get pizza at the hilariously named Pizzeria Al Capone down the street. The food was quite good, and the beer plentiful as we swapped stories and jokes. We had people from all over the globe at the table so it was a great night. Afterward we retired to the famous bowling bar in the basement of the Hotel Avanti. And of course, more beer and stories. I turned in rather late, around 1:00am, but in good shape for the next morning.
DevConf.cz day 2, Saturday.
Started out the day early again, with a 9:00am session on Cockpit. Cockpit is a new Linux server management user interface that beautifully fits the look and feel of modern desktops. It’s also has already grown a lot of capability including user and storage administration. This is a great way for us to break away from clunky and individually deprecating system-config-* tools. Instead we can move to a tool that’s more flexible, extensible, and network transparent for scalability.
Following was a talk by Russ Doty on security concerns in platform and application development. It was mainly general but made some good points about where threats usually come from (hint: not Igor the evil state-funded hacker).
Of course, no DevConf.cz event would be complete without a rapid-fire presentation from Lennart Poettering, and this year was no exception. Lennart covered kdbus, a new kernel implementation of IPC based on the excellent D-Bus. Kdbus is on its way into the kernel and will make Linux even slicker, starting with early boot and extending all the way to latest shutdown.
I also sat in on Ric Wheeler’s excellent presentation on Persistent Memory, which is next generation storage technology. Ric covered some of the challenges in supporting new types of storage in the Linux kernel, and the relative strengths and weaknesses of each.
Afterward, I went to lunch with Ralph Bean and Pierre-Yves Chibon from the Fedora Engineering team. With us were Patrick Uiterwijk and folks from Red Hat that work on infrastructure and tools for RHEL and JBoss engineers. We discussed some areas of potential collaboration, including a messaging bus for Red Hat Bugzilla. That could be an awesome new input for contributor data.
Then all the smart folks went off to find better broadband at the hotel to pore over some code together. Since I wouldn’t have been much help, I went back to the conference to catch Simo Sorce’s talk on Kerberos.
Following Simo, Dan Walsh talked about secure Linux containers. As always he was tremendously entertaining. Dan joked about how he’s been a big proponent of libvirt-sandbox for secure container support, but recently “got religion” about Docker. I hope this was taped because it was really informative. No wonder Dan’s consistently rated as a top speaker at the Red Hat Summit. (Note, you can still register for the event; I’ll be there in San Francisco too!)
Next Kyle McMartin talked about the pleasure and pitfalls of porting the Linux kernel to new architectures (hello, aarch64!). I admit a lot of this went over my head, but Kyle told some funny stories about stalking weird bugs in test suites exposed by porting. At least I think they were funny. Or rather, I think some people thought they were funny, since they were all laughing. I don’t understand kernel people, but they’re mostly lovable, and many of them have awesome beards.
Finally, I saw a talk on Arduino Yún. This model includes a small, embedded Linux computer that you can make do all sorts of cool things with the built-in sensors and other capabilities. The talk made me wish I had more spare time to spend on learning how to do hardware tinkering. Where’s my time machine?
I bowed out of the lightning talks (even though some of them looked awesome) so I could drop my bag at the hotel before the night party at Klub Fléda, a sort of warehouse-y bar/music club nearby the conference venue. With beer beckoning, it’s time to relax a bit with friends and colleagues!
Tomorrow there will be Fedora focused sessions, so I’m really looking forward to that. More later…
I’m sure you already saw my post on part 1 of day 1 of DevConf.cz, right? Well, not much time for lunch afterward — this conference is packed with content! It’s also packed with friends from around the world. Here’s a few of mine:
There are about 5 minutes between talks, and a quick 15 minute break in between morning and afternoon sessions. So after said break, I attended the following sessions:
Following the short talks, it was almost time for the conference event. I went back to the hotel to drop off my bag, and several times I narrowly avoided death by sidewalk ice. Thankfully I was walking with Fabian Affolter who would have been able to call for help if I slipped and broke anything important! (I had met up with Fabian and fellow Fedora luminary Gerrold Kassube earlier in the day.)
I quickly headed back out into the cold and a few blocks later, met up with our hundreds of attendees at Klub Fléda. There was a huge variety of good food and, of course, the omnipresent Starobrno beer. There was also live music on stage, with a power trio doing their best to entertain the sedate geeks customarily grouped together 10 meters away from the stage.
I was able to hang out a bit with some of the hardcore hackers doing great work to solve hard problems in the Linux world, including Kay Sievers, Lennart Poettering, and Harald Hoyer. I haven’t seen Lennart and Harald in a number of years — since I was in Berlin for a LinuxTag event. After a few hours, I accompanied Dan “Strikemaker” Walsh back to the hotel where we had a quiet round or two before retiring. All in all, it was a fine day and I was looking forward to day 2.
Speaking of which, stay tuned for a report for the second day of DevConf.cz!
I’ve been at the Red Hat Czech Republic office in Brno this week for meetings and RHEL-related work. But I organized the visit around this weekend’s DevConf.cz event, a conference for free and open source software hackers in Europe. The organizers in the Brno office have done a fabulous job of putting this conference together. I arrived a little later than I wanted, just before the start of the first session. That was mostly because we were out far too late the night before, bowling and having Czech pilsner with friends in the hotel basement bar! Anyway, we joined a small queue where we picked up the agenda, a ticket to the Saturday night event, and a cute gift: Red Hat branded gloves. These would come in handy in the cold and snowy, but beautiful, Brno weather this weekend!
I headed to the first DevConf.cz talk of interest to me, on color management. This talk mainly covered the current state of color management in Linux. It didn’t give me a lot of new information, but it was well done. The speaker did mention some of Richard Hughes’ work on colord. He also mentioned the ColorHug device for calibrating screen displays to get correct color. I need to pick up one of these! He also covered the OpenICC group’s formation. I have to admit, I was still just waking up, and didn’t have as much attention to give here as the topic deserved. So I apologize for the lame recounting here.
Next I sat in Debarshi Ray’s talk on GNOME Online Accounts (GOA) for users and developers. Debarshi did a great job showing how GOA works in GNOME. He had some videos that show accessing online documents from a local desktop. In the developer section, he also explained some current problems with increasingly popular 2FA schemes, and with specific service integration through GOA. Despite significant issues with some underlying frameworks needed for better GOA support, there are smart people working to solve these issues in GNOME, which was good to hear. This will give the platform a better foothold on the seamless sharing users have learned to expect.
My energy started to flag at this point, so I grabbed a quick cup of caffeinated soda and ran back upstairs to see Tom ‘spot’ Callaway’s talk. His topic was improving the Fedora user experience through design-driven methodology. I saw a version of this talk at FUDCon in Lawrence, Kansas, where it generated excellent audience interaction. I was curious to see how it was received in Brno. I was happy to see a huge turnout for this talk here at DevConf.cz. UPDATE: Spot’s slides are here (ODP format).
Spot talked about focus on user experience as the first step in development process, as opposed to “let’s write code now, and make this pretty later.” This is not a path that many open source development projects take, but it’s one that tends to produce great results for recipients. Spot followed up with some intriguing examples:
I stayed in the same room to hear Leslie Hawthorn talk about negotiation theory in FOSS projects. (You can find an excellent summary of the topic in this post on Leslie’s blog.) A fundamental lesson I took away was often we prevent a great result because we care more about a conversation’s outcome than our goals. Leslie is an entertaining and engaging speaker and I really enjoyed this talk. Hopefully I’ll get to hang out with her a bit at DevConf.cz. I feel like we’ve crossed paths often before, but somehow miss each other through happenstance.
And since I just used the word “happenstance,” I think it’s time to end this post and get lunch. Stay tuned for part 2 of DevConf.cz day 1!
Saturday was the BarCamp session at FUDCon Blacksburg. This year there were workshops scheduled at the same time as BarCamp, which was different than usual. I wasn’t at any of the workshops so I’d be interested to know from those who held them whether they felt this was useful. I do know that most of the BarCamp sessions I attended had good attendance. The sessions I attended:
Overall, this year’s BarCamp was one of the best in terms of depth of technical content. It also had an excellent spread in terms of technical complexity — meaning there was plenty for new hackers to sink their teeth into, as well as stuff that appealed to more experienced folks. We had the usual assortment of great speakers from all around the community and they all delivered impressive presentations. You should be seeing a lot of these on blogs through the Fedora Planet with downloadable content. (If you delivered a presentation, make sure you make it available widely!)
Saturday evening was the world-famous FUDPub. I was only around for a little while — since I was still trying to shake off the illness that had been dogging me since the middle of the week, I didn’t want to make things worse on my immune system by celebrating too much. Plus, it started to snow while we were enjoying the food, drink, bowling, and billiards, so I wanted to move my car back to the hotel before the roads got too dangerous. (Virginia is not known for its rapid and rational response to adverse weather conditions.) Later in the evening we gathered for poker at the “mezzanine” level of the hotel’s conference center. A few people played well into the wee hours but I headed to bed about 1:00am.
Unfortunately, the medication I took caused me to oversleep a bit, but I still managed to get over to day 3 of FUDCon by 9:00am. Once there, I got together with Peter Borsa, Pascal Calarco, and Maria ‘tatica’ Leandro to talk Insight, our Drupal installation, which the team is trying to branch out into new and useful functions. Jared Smith and Robyn Bergeron also stopped by to give some input on our calendar project. We took notes throughout the session on Gobby, and will post them on the wiki shortly along with some additional context and plans. I feel like the Insight project is starting to take on a little more life, with a designer involved and some solid ideas about functionality that will help the project.
For instance, we discussed the events calendar being able to automatically notify event owners or FAmSCo about milestones or other necessary activity, to promote better communication and awareness. A content management system makes it possible to build some fairly robust workflows around information — making the system not just another place to deposit information, but a facilitator in the process. The team has yet to figure out exactly how this should look but thankfully Maria is on the case and will help figure this out over the next few weeks. My day job is making it harder for me to lead this team, but the other members are committed to working on some exciting new features, and I’ll continue to find ways to contribute, and wherever possible remove roadblocks and continue to scale out access, privileges, and empowerment to the rest of the team.
By this time, it was close to noon. I started saying goodbyes to various people, and made sure I had picked up as many riders as I could to drop off at the airport on the way out. I ended up taking Máirín Duffy to the airport, as well as Jared’s son with me (since they live within a half hour of me). It was good to finally get home at about dinnertime. My daughter was hosting a sleepover with a friend so it was pretty boisterous at our house, but nice to see my family again.
All in all, it was a great FUDCon. I could have done without the illness the first few days, but I managed to pull through, doing a good portion of what I intended at the event. To everyone who was there, I hope you had a fantastic time and were able to really use the event as a jumpstart for collaborations of your own. Now, make sure you spread the word on what you’re doing, and carry some of that energy and ingenuity into our discussion lists and other venues! I hope everyone has or had safe travels home and we’ll see each other soon online.
