I was few times in London but always on business without time for sightseeing so decided to change it.

Day one

After few hours trip landed at London Gatwick airport. Some say that’s worst one of five but was not so bad. Why there? Because I could and I was on Stansted, Luton and Heathrow already (plan to use City one next time). Short trip to the city and hello Victoria station — long time no see…

Bought Oyster card to use public transport in easiest way and took a metro train to hotel. Nothing fancy — just cheap (65£ per night) hotel without any extras (but with working free WiFi).

Unpacked only needed things and went to city centre. Victoria monument, Buckingham Palace, the Mall etc. More or less followed the most popular trip from the “Trip Advisor” application.

Went to Thames, crossed with one bridge, looked at London Eye (and decided to skip it) and then Big Ben and Westminster Abbey were next. I considered returning to the Abbey next day but later decided against it.

Grabbed some food and went to sleep early as it was 3rd day when I woke up around 5:00.

Day two

Thursday… Skipped Westminster Abbey and went by foot to the British Museum. Met Mark Brown on a way and we had good time looking at all those things which British Empire had stolen from all around the world. We didn’t managed to find Britain sections.

After lunch I went to the Forbidden Planet store. And sunk there for quite long time. Then got back to buy two more books. This place was amazing…

They had stuff related to movies, games, tv series – figurines, key chains, t-shirts, toys, rings/jewellery, helmets, weapons and other… Some from limited editions. But when I wondered “is that’s all?” I went to the basement. And sank.

Comics, books, movies, tv series, manga, anime, photo albums and more. Books about movies, books which movies were based on (and vice versa). “Darth Vader’s princess” and “Darth Vader and his son” were there (9£ each), “Simon’s cat” books which my daughter would love (so I bought one), lot of SF and fantasy books in nice editions (Asimov for example).

“Big book of butts” looked funny. Next one was “Big book of legs” next to “pin-up girls” and other photo/erotic ones.

Nice place to go to but I warn you – you can leave a lot of cash there and have problem packing…

Lack of Britain sections in museum made me go to their website to check floor plan. And back to the building to see few more exhibitions. When I finally found what was searching for they told us to leave :-(

But no need to be sad I thought cause I was going to meet long time no see friends at a pub not so far away. Went there, ordered some “organic lager” and sat down to wait for them. Few minutes later I had a chat with some guys around 60 years old about some random stuff. Good part were their recommendations which beer to try next. As you probably guess it was not lager but rather ale or something more English.

YaaL and Pornel arrived and we had nice chat about life, work etc. Time passed too fast :-( But it was good to meet after so many years.

Day three

This had to be no museums day. First I went to visit Canonical’s office as I have never been there…

Finding building was quite easy, then discussion with security took a bit more before they finally realised that I am on a visitors list already. Got tour of the office, looked at wall full of Ubuntu Touch interface mockups, discussed few of them with someone, made some coffee and left the building.

Next step was Tete Modern Art gallery. I spent few hours there watching all those sculptures, paintings and installations which were counted as art in previous century. Did not even tried to understand those…

Due to cold I got during previous days I went back to the hotel. But why stay there when there are so many places to visit and so little time?

So I decided to make use of longer opening hours at the British Museum and went there. This time managed to see Britain sections and European Medieval times ones. It was good evening.

Day four

As this was my last day in London I decided to not go far from the hotel. Checked out, left luggage and went on foot to the Science Museum.

Lovely place. Went quickly though Space exhibition (cause most of it I saw at Cape Canaveral already) but other ones were worth seeing. Age of Steam with all those engines and descriptions, vehicles like bikes (starting with “safety bicycle” by Rover), motorcycles, cars (including JET 1 powered by gas turbine) but also planes (with replica of Wright brothers one) and helicopters.

I enjoyed the “Materials” exhibition — especially body model with some artificial addons and long list next to it informing which materials can be used for which implants and other inserted parts.

There was also special exhibition about Alan Turing and his work.

After visit I went for food, took luggage from hotel and then the Underground to King’s Cross train station and went to Cambridge. But this will be next post.

My UK trip — London was originally posted on Marcin Juszkiewicz website

I plan to visit London and Cambridge on 16-22 May. Just for sight-seeing and meeting friends — no business this time.

Plan is to meet old OpenedHand fellows, some old friends from Poland, maybe visit Canonical office just to see it (as I work for them for nearly 3 years). And of course see something cause I was few times in London but managed to see only train/metro stations and nearly nothing more.

Then Cambridge for 40th Cambridge Beer Festival. There are friends to meet as well and maybe see something as well (but here I saw far more things than in London).

As usual flights from/to Berlin to one of London airports (plan to return from Stansted as it is the easiest to get there from Cambridge). Need to sort out some places to stay.

Also have to check which UK prepaid is useful today. I need few gigabytes over HSPA — previously Giffgaff was fine for it for just 10 GBP but they have changed rules. Tethering required due to tablet and Chromebook (which I plan to get repaired or replaced).

Any suggestions for 3G or place to stay?

Time to visit UK again? was originally posted on Marcin Juszkiewicz website

This year I spent Easter in other way than in past years. Instead of staying with the family I went for demoscene party — Revision 2013 in Saarbrücken.

Please note (RSS readers mostly) that this post will contain many YouTube videos embedded. Please go to my blog to have them properly displayed (I use WordPress + Jetpack plugin to embed them).

Friday

Took us 12 hours to get there (mostly due to waiting on TXL and FRA airports) but we managed to be at party place around 19:00 on Friday. Registered, met friends and went to Kirchberg Hotel to drop bags.

Hotel has two stars but was perfectly fine for such trip as our. Clean bed, good breakfast, quiet place (except church bells at 10:00 on Sunday). All just ~2km from E-Werk where Revision took place.

Back to party, more people to meet, discuss a bit with guys from ARM Ltd about Samsung Chromebook, Cortex-A15, Mali etc. One guy joined with his Chromebook and recognized me when I asked “may I fry your speakers?” :D

Timetable listed one interesting thing: “Curio’s 2012 Essentials” which was ~1 hour long set of PC demos from previous year. It was nice as I was totally out of PC scene so was able to check how it looks.

Taxi to hotel was just 6€ ;D

Saturday

Attended “How to start writing compilers without a Ph.D” seminar as it sounded interesting to me. And it was ;) Video below:

Also had discussion with ARM guys about presenting not only technical demos (like Unreal Engine one) but also to show some demoscene productions. Soon “Beginnings” by Elude started on one of Nexus 10 tablets and was working nice. But coder who wrote it was not so happy about that when we discussed that later… I think that it would be a good thing for ARM Mali team to get some good demoscene groups to write demos for Android platform to amaze people with nice looking productions. ARM even had seminar for OpenGLES 3.0 API:

But Saturday was also full of competitions. Tracked music, oldskool music (read: 8-bit mostly), photo, animation/video, game, ascii/ansi, Amiga intros, PC 4K intros, Oldskool demos (8-bit, Atari STE, Amiga 500)…

There were many entries in compos where productions from long time no see groups/people were presented. For example in oldskool demo we got “RINK A DINK REDUX” from Lemon which was astonishing:

There were also demos for Amstrad CPC, MSX1, ZX Spectrum, Commodore 64 and other platforms. Oldskool music compo had even NES entry ;)

But it was also visible that demoscene is not full of amateurs like it was years ago. Some of videos in animation/video compo had professional level. “Lübeck 24x7x365″ took 50 days of recording but was really nice:

There was a concert in the evening… Ear plugs were not strong enough for me so I spent most of time outside talking with people. Next time need to take some better hearing protectors…

Sunday

As Saturday ended really late for us and competitions were planned for 13:00 we decided to not rush and stay in bed longer :) But at around 10:00 bells in local church started their music compo so we were not able to sleep anymore.

We got music, graphics, wild and of course PC 64K intro, web browser demo/intro, Amiga demo and PC demo competitions that day.

Graphics one was won by “Double Trouble by the Royal Forces” made by forcer & prince. Huge amount of details which was not so visible on big screen as it was on a tunnel’s wall where it was hanging as few square meters photo copy.

Wild compo… Man, that was something great. From productions made for Arduino (with some shields) though ARM Cortex-M3 one to interesting hack by Dexter/Abyss which shown one view on monochrome TV and second on oscilloscope while both were connected to Composite video signal only… See it for yourself (or grab separate entries from scene.org FTP server):

Then DJ set by h0ffman (skipped by me) and clue of party — Amiga and PC demos/intros. Different quality but most of them was really good — both from technical or design view (but not always from both at same time).

But as I am not a coder I looked mostly at design and audio/video part. All those names like ‘ray matching’ etc meant nothing to me so when someone tried to explain why demo which I did not like was so great I just told similar thing ;D

Monday

Wake up, breakfast, pack, pay, go to party place. We did not manage to get there before voting ended so not voted for PC demo compo entries. Greeted those who was still present, discussed a bit and then return trip… This time just ~9 hours but next time (if there will be such) we plan to go there by car. Less time needed.

Random stuff

I liked how party was organized — it was my first such event abroad and many people told me that Revision is the last demoscene party in old style. I really liked it. Saw many different platforms like MSX1, MSX2, C= VIC20, Amstrad CPC or Videoton…

Due to Easter time shops where closed on Sunday/Monday but it was not a problem for me as there was free coffee/tea, beer/water/orange juice was available to buy at low price (2.5€ for 0.5l beer) and there was hot food served all time (like 10:00 – midnight) also not so expensive.

Weather could be better as it was cold but at least there was no snow (which we still have here).

It was also nice to see Kiero at work as he was finishing “Machinist” Amiga demo on his x86-64 laptop with WinUAE running fullscreen. I was surprised that ASUS UL30A is capable to run it fast enough.

Amount of discussions with people is probably uncountable. Chromebook, ARM, Android, Amiga, scene were just subset of topics…

Will I go there next year? Will see…

Revision 2013 was originally posted on Marcin Juszkiewicz website

Second day in a row I managed to get 8 hours of sleep like I was not able at Linaro Connect Asia 2013. There was no time for sleeping as so many things had happened.

This time I decided to go to Hong Kong on Friday to have whole Sunday for shopping or sight seeing etc. Also to make things different I went though Helsinki (was Istanbul in 2012). It was interesting experience to hear English language with Finnish accent. There were moments when during in-flight announcements I was not able to recognize when they ended Finnish part and started English one ;D

HEL was cold but only outside so once I got to terminal it was fine. Rushed though, passed biometric passport gate and got a seat with electricity to charge my Chromebook and phone. Flight was “fine” as usual but as it was during night I tried to catch some sleep.

Finnair’s crew had some problems getting in-flight entertainment system working so we could watch how Linux booted on those NSC Geode GX2 based devices. Due to copyright note in bootloader (redboot) I assumed that it is not older than 9 years. Very slow boot anyway with lot of text printed. They should show some splash + potential progress bar instead. But finally it started working. Provided in-ear headphones are much better than ones on Lufthansa flights.

Landed, got prepaid sim from “3″ network, met Andrea Gallo and we went to hotel. I had plans to go to the city center but was too tired for it. I also lacked HKD due to other layout of keypad in ATM :D

On Sunday we grouped and went to Shim Shui Po to do some electronics related shopping. Prices in Hong Kong are similar/worse than in Europe so I bought only few things which I had problems finding in low price at home: mini-ITX case (16€), Nexus 4 back cover (6.5€), case for Samsung Chromebook (7.5€) and some cables. There are still no USB 3.0 cables in wide selection ;( I also bought crappy dual sim phone for 10€ as I needed one to get my Polish sim on network.

I also did some shopping on Tuesday — this time on Ladies’ Market. It is one long street with lot of sellers with clothes, wallets, toys, phone covers, headphones and other gift like things of unknown quality. I left there all money I had but got gifts for everyone I wanted. Haggling there is a must as 40% of starting price is easy to get. And you do not even need to tell anything to get price lowered…

We also went to Shenzen, China for one afternoon but that’s story for separate post.

But I went there for connecting with people. And to discuss/present our work done in last cycle and to be done in next ones.

Each day started with keynote (Friday one had Linaro awards). And we got speakers from outside of Linaro:

• Jon Corbet (LWN)
• Lars Kurth (Citrix)
• Jason Taylor (Facebook)
• Greg Kroah-Hartman

Each talk was interesting. Jon shown Linaro developers that Big.Little switcher should be taken for community review earlier, Lars presented Xen on ARM (v7, v8), Jason told about how Facebook handles servers and where is a space for ARM ones. Greg’s talk was best — he told why he does not want our code, what kind of mistakes people do in sent patches and gave us story how one code submission can break whole set of devices due to lack of testing. I wonder how Linaro Kernel WG will handle Greg’s new requirement of having all Linaro patches signed by senior kernel developer.

This was also first conference where I was fully ARMed. I left my x86 laptop at home and took Samsung Chromebook instead. Ubuntu runs fine on it, speed is comparable but size (13.3″ contra 11.6″) and weight differ. This also gave me few more occasions to talk with other developers.

I spoke with Citrix guys about Chromebook kernel changes and their Xen backport will probably be merged into “linux-chromebook 3.4″ package. Also had some discussions with ARM Mali developers which resulted in removal of OpenGLES packages from Chromebook support PPA due to licence issues (I do not have redistribution permission).

We also had meeting about hacking Samsung Chromebook where ChromeOS, Debian, Linaro, OpenSUSE, Ubuntu developers had discussion about what we can expect, where we are, how to get some things fixed etc. After that Nicolas ‘Charbax’ Charbonnier from armdevices.net shot video about it:

Direct link to video

I remember that Charbax tried to make interview with me at one of earlier Linaro Connects but I always rejected that idea. This time he went for help… And I could not refuse to Zack Pfeffer :) How it went? You tell me:

Direct link to video

Hong Kong was great. Weather was perfect with +25°C, sun and no rain. Someone told me March is the last moment for being there :)

But then I had to leave. Problem with return flights is that they usually are around midnight. Add lack of sleep during previous nights and result is not nice mix. So we spent some time in airport lounge to charge batteries (our and devices) and then squeezed in economy class for 11 hours. Took a nap, watched movie in English with Finnish subtitles (learnt new word even) and read “Amiga, the future was here” book.

Imagine weather change when we landed in Helsinki… -13°C and snow. As I left my spring jacket in checked-in baggage (but I had sweater) those few minutes from airport -> bus -> plane were cold ones. Similar few hours later in Berlin. But I had some time for shopping. Skipped salmiakki cause it is hard to know which ones will be hardcore just enough but got some other things.

Szczecin was nice on Saturday. Cold, but spring was visible. Winter came during night:

Next Linaro Connect will be in Dublin, Ireland. See you there!

Linaro Connect Asia 2013 was fun was originally posted on Marcin Juszkiewicz website

There will be Linaro Connect Asia next week. Which means: I am going to Hong Kong today. 21-22 hours trip like usual. This time through Helsinki ;)

But recently I started to count and got quite long list of Linaro events I attended so far:

• 2010.05 UDS/M – Brussels, Belgium
• 2010.07 Ubuntu/Linaro sprint in Prague, Czech Republic
• 2010.10 UDS/N – Orlando, FL, USA
• 2011.01 Ubuntu/Linaro sprint in Dallas, TX, USA
• 2011.05 LC + UDS/O – Budapest, Hungary
• 2011.07 Ubuntu/Linaro sprint in Dublin, Ireland
• 2011.10 LC + UDS/P – Orlando, FL, USA
• 2012.02 LC – Redwood City, CA, USA
• 2012.05 LC – Hong Kong, China
• 2012.11 LC + UDS/R – Copenhagen, Denmark?

The “Linaro Connect” name is quite young and I do not remember which event got this name first. There will be three of them this year: Asia, Europe, US. But when and where? Do not ask me cause so far it was not announced yet.

So if any of my readers will be in Hong Kong next week — please say hi. And there will be Chromebook hacking session on Tuesday at 15:00 in Fountain 1 room (but please check schedule/ask me if not changed).

I am going to Hong Kong was originally posted on Marcin Juszkiewicz website

Year ago we had Linaro Connect right after FOSDEM so I decided to skip and walk to Golden Gate instead. But this year there were no conflicts!

Months before we had discussion on SzLUUG mailing list about who goes for FOSDEM. There were about 9 people wanting and we ended with five. So on Friday morning friends arrived near my house, I jumped into car, we grabbed 4th one (Tomek was in London at that time) and went to Berlin Schönefeld airport for 07:00 Easyjet flight.

And we missed it… 5-10 minutes late we were ;( 75€ per person and 10 hours later he took off from SXF airport.

But that 10h was not wasted. Berlin has very nice Technical Museum with many trains, cars, planes and other exhibitions. And they had Trabant 601 as well:

Then trip to shops (Saturn, Media Markt) in search for HTC Desire X case (Magda) and LG Nexus 4 (me). Avoid Saturn — they do not handle credit card payments at Alexanderplatz so I had to walk to the ATM. Two S-Bahns later we passed security check and went to the gate early enough to fly.

BRU airport… I think that (with exception of SXF/TXL) it is my most visited airport as it was my 5th FOSDEM and there was UDS-M around as well. But this time we took a bus instead of a train. 14€ ticket works for 72 hours so cover all trips perfectly. Few hours later we were joking that this multi country journey was exhausting as we were in Berlin, Brussels, went though Geneve (bus stop) to Luxembourg (square) and passed near London (restaurant) ;D

Hotel, drop stuff, connect chargers, went for beer event. Crowdy as usual it was. But I managed to meet some friends (but also missed lot of them) and grabbed few beers. Good spent time. Too bad that I was so tired that went back to hotel just right after midnight.

Saturday

Breakfast in St. Nicolas hotel maybe is not the best but provides enough energy to survive a day. Met several guys there, Philip gave me Kindle Paperwhite which I bought few days before (with delivery to his house to lower price) and his famous Belgium/Holland/Luxembourg guidebook. I also got Beagle pendrive from Koen.

Then overcrowded bus 71 and FOSDEM! I told Bartek where things are (but at that time I had no idea of K building) and we split. In AW building I met friends manning OpenEmbedded stand just right in front of building entry.

Circuitco had Beaglebone stand right to it:

That robot was great example what you can do with enough signals available to drive all those motors. And what you can do with 3D printers ;D

I do not know is it due to crisis or something but AW building had just half of a space for stands used…

Then I went for talks:

• “Embedded distro shootout: buildroot vs. Debian” — wasted time. Long discussion about Emdebian + short info that Buildroot works in other way. Could be nice talk if done in other way.
• “Porting Fedora to 64-bit ARM systems” — talk done by Jon Masters and his clone. As usual first “what the hell is 64-bit ARM” and then how Fedora bootstraps itself. Nice talk, got some new stuff. Have to dig for Cavium SDK.
• “Porting OpenJDK to AArch64″ — interesting it was. Two speakers, lot of technical details.
• “ARMv8, ARM’s new architecture including 64-bit” by Andrew Wafaa. Mostly to catch speaker in easy way ;D
• “Bootstrapping Debian-based distributions for new architectures” – I was lazy to go somewhere else but it was good talk.
• “Bootstrapping the Debian/Ubuntu arm64 ports” by Wookey. Kind of recycled talk from Barcelona but I like his presentations. Also first one without “what the hell is armv8″ introduction.

I also had nice discussion with Jolla guys about their system/device and would I like to test it once they will have something ready for complains. Played a bit with Firefox OS on their reference developer platform and on Nexus S and was not impressed — for example it looked like they have to learn about DPI…

Then I met OE crew and few other guys and when finally noticed that it is time to go to the hotel and drop gear there. Once arrived it was a bit to late to go somewhere and search for some event so I joined SzLUUG team and we went for a meal, chocolates and then some drinking with Kerneliusz (SzLUUG mascotte):

Sunday

Breakfast, packing gear and go for a bus which was less crowded than day before (but we are a bit late as well). As we had to leave after 14:00 I managed only two talks:

• “systemd, Two Years Later” — some Ubuntu trolling and project status. Nice talk.
• “Porting applications to 64-Bit ARM Architecture” by Riku Voipio (main AArch64 porter at Linaro). Good discussion in a room, some nice hints and suggestions. Read his recent blog post about ARMv8 porting

Then walk, tram, bus and security check. This time I did not have to take developer boards from backpack as I gave them away during event. We arrived in Berlin and (due to Micha?’s fosdem flu) I drove us back home.

Summary

It was great event as usual. But distance between K building and rest was too big for sessions which are one after another. I dropped some entries from my calendar just because it would be H->K->H->K switching.

Android application for schedule was ok. Would be nice to make a bigger effort and update it to cover K building as well and add a way to see what is going on in each building/room to reduce time before sessions.

Funny part

On Saturday I realized that for some reason I may remind Jon Masters… That’s due to hardware I had with me:

• two developer boards
• two phones
• two tablets
• 3 USB chargers
• 4 microUSB cables

The good thing is that they were not of same type (except some cables) :D

FOSDEM 2013 was originally posted on Marcin Juszkiewicz website

This year no one blocked me from going to FOSDEM ;D

What are plans? There will be some AArch64 related talks which I want to attend:

• Bootstrapping Fedora for AArch64
• Bootstrapping Debian/Ubuntu for AArch64
• Porting software for AArch64
• Porting OpenJDK for AArch64
• What the hell is AArch64

Few ARM ones:

• Freedreno update
• Open ARM GPU drivers
• ARM status in Linux kernel

Few for entertainment:

• Buildroot contra Debian
• Baserock introduction
• Eudev

Some for curiosity:

• HipHop
• Why there is no such thing as FOSS phone?

Original titles may differ. There are over 450 events during FOSDEM, several keynotes etc. There will be also few thousand people so I would rather not find a time to attend even half of sessions listed above… But for me this is how this conference work :D

Normally I do not take hardware with my (other than phone). This time I packed two boards, two tablets and hope to get rid of most of them ;)

Going for FOSDEM was originally posted on Marcin Juszkiewicz website

Another week of conference passed. This time I was at Linaro Connect q2.12 which took place in Hong Kong Gold Coast hotel.

As usual everything started with packing. I have a list for it so it is usually quick job but you know — I was going to Hong Kong, world capital of cheap electronics so better have some space available just in case. So I borrowed bigger bag from friend, put some Linaro stickers on it (to be able to find it at baggage claim) and put all my stuff inside. Of course travel things went to backpack (have to buy more comfortable one).

And then trip began… In short: car, bus, wait at airport, plane, wait at airport, plane, catch Rob Clark, taxi, hotel. Total time: 22 hours.

Hotel was nice. View from room at “15th” floor (which was 12th due to 4, 13, 14 missing):

Monday went with meeting people, sessions (scheduled and random ones) and some hacking. At end of day we had usual “meet & greet” dinner which was rather “seat & eat” style as we had it in room where we has lunch and there was not enough space to walk and discuss with people. For this I prefer UDS style where you have few points with food/drinks, lot of walking space and some tables here and there so you can grab something to eat and chat with many people during one evening.

Speaking of food… It was great! Breakfasts offered wide choice of Chinese, Japanese, Singapore food with Western options available too (some sausages, boiled eggs, British beans). Add fruits, sweets and all what was there to make sandwiches… Lunches were even more mixed. Something local, something European, salads, sweets — all that made me a bit heavier on return trip :D

Many people were surprised by lack of soda options as only coffee, tea and bottled water were available daily. For me it was not a problem as coffee + water were more than enough.

But back to sessions. There were many ARMv8 (aarch64-gnu-linux) sessions. I attended one of them where we discussed about building cross compilers, bootstrapping distributions etc. As rest of ARMv8 ones this was not broadcasted or recorded. Rest of sessions used Google Hangouts for remote participation. It worked well even with last-minute changes from Google which terribly broke setup we used for earlier Connects. I was on session where leader (Wookey) was remotely so we had “big brother is watching you” effect:

Have to admit that this method of remote participation helps as users can just ask questions instead of relying on someone following IRC channel. But it is also limited to who can join so no use for conferences like UDS.

For me interesting sessions were ones around CI process. We have few such systems and each has different use. There is LAVA which gives us ARM boards to run tests on, Jenkins to run builds on x86 instances (Amazon EC2 like). Toolchain Working Group has “cbuild” which they use to build and test toolchain on x86 and ARM machines. And then there is also Launchpad which has daily builds from selected Bazaar branches. We had discussions about merging them and/or sharing resources (like a way to borrow ARM boards from LAVA to run cbuild). Hope that we will get something interesting from it.

But sessions are not the only thing to do. There are also after work activities. We got coaches available on Tue/Wed/Thu to Tsim Sha Tsui (TST in short) district, The Peak (Tue only due to cloudy weather) and somewhere else. I went to TST on Tuesday and we just walked around it, got some food (chopsticks only so we decided to not ask for cutlery and handle it — we managed) and for fun visited one of those shops with “TAX FREE” signs (which in tourist language means “YOU DO NOT WANT TO BUY HERE”).

On next day I went with Zygmunt Krynicki to Golden Computer Shopping Center near the Sham Shui Po station. Lot of computer shops compressed in small area. Everything from SSDs, mainboards etc to normal and weird cables. In one shop I asked for 0.5m long HDMI cables and got them so expect soon post about adding HDMI switcher to my devboards setup. Decided to not spend money on anything more expensive as there is no warranty that it will work and I do not want to ship hardware back to Hong Kong when it fail.

Thursday we want for team dinner. But before we decided to take a ferry from Avenue of Stars to Hong Kong Island and go for ice cream there:

I went for ginger and green tea flavours as both sounded crazy enough and I am sure that will not find them here in Poland. Ginger one was great (even if I do not like ginger) but green tea one was awful — tasted like concentrate of concentrated tea.

Then we went to “Spring Deer” restaurant. Crowdy, long queue (even with earlier registration). As usual in Hong Kong I had to watch my head in few places. When we got table it looked like disaster but got cleaned quickly and were served with food.

For start they give us some oiled peanuts so we had interesting challenge as a way of practising eating with chopsticks. We ordered some pork, fish, vegetables and duck.

After dinner we were able only to grab taxis and go back hotel ;)

Friday was my last day there. During packing bag I realized that this is my first conference when do not have any extra hardware (cables do not count). But I hope that sooner or later I will put hands on some kind of ARM server hardware (maybe one node Calxeda board which I heard rumours about). As there were nearly no sessions I went to one of hacking rooms for coding and got my patches reviewed by Matthias Klose — have to work on few of them, some were described as “have to merge as look ok”.

After lunch we had usual “Demo Friday” where people presented work of miscellaneous Linaro (but not only) teams. One of interesting ones was comparison of ASOP build of Android 4.0.4 contra Linaro build which was present on two same Pandaboards. Both were running 0xbench and results were cleanly visible. Changes are in review and on a way to ASOP tree (due to usual “Upstream, upstream, upstream” philosophy of Linaro).

Day ended with dinner in Chinese style. Food was good and interesting — especially when we were trying to find out what menu entries mean ;) There was a show of Chinese “Bian lian” art with a guy changing his masks. I was wondering for a moment how we did that but did not bother with it too much.

20:15 was bus to airport. Then usual stuff: wait on airport, plane, wait on airport, plane, wait on airport, bus, car, home. This time 26 hours. Saturday evening was a bit hard but with a help of melatonin I managed to get rid of it with 8h sleep. So this is first trip without jet lag problems.

Another May, another Ubuntu Developers Summit. This time I am in Oakland, California, USA (even if my tweets shows Dallas, Texas as geolocation).

As usual with US trips this one took insane amount of time. But I was 3cm from not going here… Why? Because I got stuck in toilet at home. Hopefully with help from neighbour I was able to bash door out and get to the bus stop on time.

Then standard set of bus, plane, plane, train and finally arrived in hotel. As my room was not yet ready I got 30$ coupon to bar to not waste time on waiting. Free meal/beer ;)

My room is at 17th floor (which means 15th) and has a nice view in the evening:

On Sunday I went to see San Francisco centre (I saw Golden Gate on earlier visit). Chinatown was interesting experience. Lot of people speaking language which I do not understand, shops full of food which I do not recognize.

Some random photos:

After getting some souvenirs and refilling of my US T-Mobile sim card I decided to go to the cinema for ‘The Avengers’ movie. It was nice experience. Touchscreen operated ticket machines which allow to buy ticket in one minute (but people were standing in long queue to buy tickets in ‘normal way’) made it even better. As in Poland there was big amount of commercials before movie (including some in style “our Army/Navy is great, why not join us”) but what I liked was just-before-movie animation reminding about not talking/texting/tweeting during movie (made with characters from “Madagaskar” series). Have to admit that RealD 3D glasses were more comfortable than Dolby 3D ones used by Polish cinemas. Movie itself was great but I think that will have to see it in Poland due to my English ;D

During evening there was usual Canonical internal plenary and then dinner. I even managed to sleep 6 hours despite jet lag ;D

Monday started with interesting keynote and presentation of Calxeda ARM server using technology they were talking about at previous UDS. Photos:

It is 2U case with 24 Serial-ATA discs and 12 nodes with 4 quad-core EnergyCore processors per node. The only cables inside are power ones as rest of connections is on pcb. Connection with world by four Ethernet connectors.

I went to “Create filesystems for embedded devices” session where we discussed how to make Ubuntu Core even smaller. People mentioned OpenEmbedded, OpenWRT, buildroot as usual, we got some strange use cases too. What will come from it? Time will show.

Plenaries were interesting. First Chris Kenyon told about cooperation with OEMs and ODMs and how it relates with Ubuntu. Laptop in a pizza box picture was nice — reminded developer boards. Then Bdale Garbee from HP shown us that there is no way to go though life without being served by HP technologies or hardware. Both talks were great and I hope that rest of plenaries will be like that.

After plenaries I went to San Francisco to register at Tizen conference and to meet some friends from Maemo times. Technical showcase and partner demos were boring and it was hard to feel that it is something innovative. But who knows… maybe Tizen will be yet another phone/tablet/ivi/etc OS even when Moblin, Maemo, MeeGo did not succeed.

During evening (back at UDS) there was ‘Meet & greet” social event. Our Linaro group (Amber, Ricardo, Paul, me) was showing member boards and replying to misc questions from audience.

What next? Sessions, social events, discussions about my patches with other developers, some sight-seeing.

During my trip to Linaro Connect 2012q1 I want to buy Android tablet for myself. But this time I decided to spend more time on choosing one to not end with crap like Hannspree Hannspad which I bought half year ago.

Also situation on market changed. There are cheap tablets worth checking but there are also cheap crappy ones. So let me list what I checked so far.

As you see my requirements are more or less simple:

• dual core cpu (arm7)
• 512MB ram (1GB preferred)
• 1024×600 (or higher) resolution
• 7-8″ screen size (I had 10″ and it was too big)
• price below 300USD

During CES many vendors presented new tablets but I think that most of them will be released in Q2 or later. ASUS MeMo 370T looks nice for 250USD but it is not on market.

And I do not want 3G module in tablet — my phone has over 10GB of data limit to use for next months and so far I was not able to consume 1GB per month :)

Have I missed some devices? If yes then please share information in comments. Just remember that I do not want any of those NotionAdam/Viewsonic/Hannspad ones.

Want to buy Android tablet (again) was originally posted on Marcin Juszkiewicz website

In March I wrote where I will travel. Decided to write such memo at start of year so it will be more visible what my plans are for 2012.

In February I will miss FOSDEM because Linaro Connect Q1.12 will start right after it. So at 4th I will fly to San Francisco for a week. But this time instead of flying back home I decided to spend weekend in New York City where I hope to meet some people from Bug Labs company. You know: we worked with each other for 1.5 year and I met only Peter Semmelhack and Ken Gilmer. Also I plan some sightseeing.

Then a bit of quiet until next Linaro Connect will happen. Probably May but it was not yet decided where and when. As many people I also hope for Asia (never was in this part of world).

Same month there will be Ubuntu Developer Summit somewhere at west coast of USA. Who knows — maybe it will end in trip around the world in May? Sounds interesting but I think that only sounds as it can be hard to survive due to jet lag.

Then July/August another Linaro Connect. No idea where, but hope for Europe. In meantime I may or may not attend Ubuntu Rally (Canonical internal event) which will be somewhere in US (as it follows UDS place).

And end of year will bring yet another Linaro Connect and Ubuntu Developer Summit. Second one in Europe.

What else? Probably LinuxTag if company events will not be at same time, maybe something local (there are few conferences planned in Szczecin).

Overall it looks that there will be some travelling — but this year I plan to make more use of free time to see something else than conference centers.

Events in 2012 which I will attend was originally posted on Marcin Juszkiewicz website

As I did not had a mood to blog during event I decided to write something about after it ended.

First what this Linaro Connect is about… Is it conference or rather an event which has to gather people in one place so they can reach each other easily? From what I saw during last week it is both.

There were several summits which I did not attended so does not have anything to write about them. Inter team meetings during which people were sharing their knowledge about their work and how to use it to improve work of other teams — here the most active were Android and Validation teams (in my opinion). Schedule was full of Android sessions and LAVA was quite often heard word.

For me event started on Sunday as I had taxi at 6:30 in the morning. Then bus, plane and then waiting 2h in terminal 1 of London Heathrow airport waiting for few other guys to appear as we had to share a cab to hotel where I arrived at ~17:00 local time. Yes, my travels sucks.

Went outside with Zygmunt Krynicki to find some place to eat. Found few takeaway only places and small restaurant with India food which was delicious.

Monday started with traditional English breakfast (you know: eggs, bacon, sausages, fried bread, baked beans and mushrooms kind of one) which was quite good and we had it daily. When it comes to food at hotel it was good and someone had great idea serving different cuisine each day.

Starting plenary with informations from each team about what do they plan for this week. Then work, meetings, coding, hacking etc. Attended several meetings like binary toolchain discussion with toolchain working group, Matthias Klose from Ubuntu and several people from ARM Ltd which maintain ARM Development Studio 5 (DS-5). Also went for hard float summit with not only Linaro or Ubuntu but also Fedora and Marvell people.

But work is not the only thing we did. There were activities for evenings too.

On Monday we went outside for karting. First we were equipped with proper suit, shoes, helmet and then went for safety instructions.

Racing was fun. Each team were split into two sub teams (as there were two tracks) with 4 people in each. That gave 15 minutes per person, but as one of us decided to not drive second one we had 20 minutes on it.

Was it fun? O yes, it was. Especially outside track where speed was higher and engine more powerful but as steering was tough my right wrist reminded me that RSI problem which I had few years ago (this time pain vanished during night but got back at closing party). Our team took 6th place in total.

Tuesday and Wednesday evenings were “reserved” for team meals. First day we went to Browns and Punter was next one. Food in both was tasty and came in big amounts.

But food was not the only way to spend evening. On Wednesday we went punting on a river in Cambridge. Our punter was presenting us with informations about colleges and bridges we were passing by — things like who created them, when, why etc. Some people took photos but so far I did not traced whom to contact to get a copy.

Thursday we had a dinner in King’s College. Dinning hall looked nice with all those portraits and food was good. Had a nice talk with ST-Ericsson people about their cheap developer board Snowball which I complained about in other post. We got to the point that the CPU on board was created for mobile devices use (that’s why no usb host functionality) and that all those industrial connectors are present because it is more board for prototyping new devices.

Friday was last day. We did some hacking, packed equipment of our room and prepared for closing plenary. At the end we had small party with some activities and food. I left it early — was tired and wanted to discuss with Zygmunt a bit (normally we chat often during company events but this time we got separate rooms).

Return trip was a copy… taxi, plane, bus, taxi. Went home around 22:00 and gave inflated sword (from closing party) to my daughter — she liked it ;)

Last week there was Ubuntu platform sprint in Dublin, Ireland. I was there as one of invited Linaro guys (we got own room). What for we went there?

Work. Simple word but so much content in it. Sprints like this one allow to cooperate with other developers and this time I spent some time with Ubuntu ARM, Foundations and Kernel teams. But most of time I spent with Linaro guys as we had release of 11.06 to do.

My part was building cross toolchains for Ubuntu — including few already released ones. So I pushed several updates to ‘oneiric’, ‘natty’, ‘maverick’ and ‘lucid’ versions:

• binutils 2.21.52.20110606-1ubuntu1
• gcc 4.4.6-3ubuntu1
• gcc 4.5.3-1ubuntu2
• gcc 4.6.0-14ubuntu1
• eglibc 2.13-6ubuntu2
• linux 3.0-1.2

If you are running 11.10 ‘oneiric’ then all you need is just apt-get install g++-arm-linux-gnueabi and will get cross compiler. For “armhf” compatible one apt-get install g++-arm-linux-gnueabihf needs to be used. For those which run older releases there is Linaro toolchain backport PPA where packages are available for “amd64″ and “i386″ architectures.

Other part of my work was related with Star rating system which we plan to use to show status of boards supported by Linaro. I did some tests with PandaBoard connected to two monitors at same time and reported several bugs. Situation is nice but many things still need work.

At one moment I was creating “lucid” chroot on my “oneiric” system to be able to compile toolchain. And then I got a problem which ended in bug 802985 which needs fixing in all supported releases… Also debootstrap needs to be expanded to handle multiple suites at one time — otherwise there will be no way to populate chroots with older releases on any machine running 3.x kernels.

But work is not the only thing which we spent time on. Evenings were usually in pubs or similar places.

On Monday I went to hotel bar, grabbed a beer and started discussing with some random people. At one moment (when we were talking about OpenZaurus) one of them asked who I am and then went and bought me beer — he was Zaurus user whom I helped in past ;) So never know who you can meet…

As I have few friends in Dublin area I contacted them and on Wednesday evening I went with one of them to Club Chonradh na Gaeilge Irish pub where speaking English is nearly forbidden (but we were using Polish so no problems :). There was one bard singing Irish songs. Nice place, nice event.

Thursday was team dinner — went to Rustic Stone. Nice place, awesome food:

Friday was a day when many of us started packing and some even left earlier to catch flights. As Wookey asked me week before sprint to take my N900 with me we made a deal and I got some Euros and he got phone with all accessories. So guys — now really no more Maemo support from me (not that I did anything in this area since move to Nexus S).

On Friday also other part of visit started for me — my wife Ania arrived and we went to our family to spend nice weekend in Ireland.

We drove to Howth, spent some time looking at area from highest(?) mountain:

Then beach in Portmarnock where my wife started collecting sea shells… Quickly we got lot of them but I managed to put them in luggage somehow ;)

Evening was funny as we had to meet with one of my old friends. The “problem” was that we never met in real life yet and I forgot how does he looks. When I told that to wife and rest of group they were really surprised that such thing can happen ;D But we found each other and went to the Church Bar which is made from old St. Mary’s Church of Ireland which is one of the earliest examples of a galleried church in Dublin. Built at the beginning of the 18th century and renovated in 21st century. Nice place to visit in Dublin.

On Sunday we went into Wiclow county. Upper Lake at Glendalough then Glenmacnass Waterfall and few stops during trip to watch landscapes:

Monday was different — we went to Dublin for normal sight-seeing. You know: buildings, churches, castle…

Then packed bags and went to airport. The good part of Aer Lingus is that there were no problems with checking-in two bags on my ticket (but queue to just drop bags was insanely long). 2h flight, then another 2h in a bus and we finally arrived home. This part of conferences trip I like most — arrival at destination (as in Europe trips can take even 9h for me).

Dublin: Ubuntu sprint and more was originally posted on Marcin Juszkiewicz website

This week I am in Budapest, Hungary attending Ubuntu Developer Summit for 11.10 ‘oneiric’ release discussions. But this is not only Ubuntu — there is huge amount of Linaro people discussing what to do next cycle.

Sunday

Travel, travel, travel… Usual way — bus from home to Berlin airport (SXF this time) where I met with Henning ‘woglinde’ Heinold to donate my old Linksys WRT54 which I got donated few years ago to be able to use my Zauruses wireless. Router had to be in use on OpenEmbedded stand at LinuxTag, Berlin — go there and visit them at booth 7.2b 112.

Again flight was with Easyjet. It is cheap airline but with speedy boarding it is good enough to go with. Bad side is that it lands at old terminal 1 in Budapest so I had to go to hotel by my own.

Evening was Canonical only meeting where there was a presentation of some things which will go into 11.10 Ubuntu release (nearly same to next day keynote). After food, discussions and finally sleep ;D

Monday

Sessions started — I attended few:

• Ubuntu LEB documentation
• cross toolchain user stories — my own session where most of time Micheal Hope was telling us about requests which Toolchain WG got
• user stories for nano image
• DMB regular meeting — I became Ubuntu developer during it!

During evening was ‘Meet & Greet’ social event sponsored by Openstack and Freescale. Nice way to catch with people. Especially when you meet old friends which you never met in person ;D I met Marek Szyprowski which whom I was writing to Polish Amiga paper magazine named ‘eXec’ (but website with similar name does not have nothing in common now). We talked for quite long time about misc things. Also met some other folks, refreshed faces memory etc.

Tuesday

Sessions:

• cross toolchain user stories (again) — we discussed notes from previous day, decided on some details and created work items so I can start working on it
• Ubuntu LEB documentation (also again)
• Linaro Ubuntu LEB process for 11.11
• GDB as cross debugger

As you see LEB was topic of a day. And it was not everything — next day was another session.

Evening was taken by The Linaro Technical Showcase sponsored by IBM. What was there? Many interesting things:

• Arnd Bergmann was talking why class4 SD card can be much better then class10 one
• Freescale Landing Team was presenting i.mx53 Quick Start boards
• Ash Charles from Gumstix was presenting their new miniboards with DM37xx cpus and few carrier boards
• Pawe? Moll from ARM was presenting Cortex A15 running from two biggest FPGA chips. It had just 11MHz clock but it was enough to show Doom game running on connected monitor.
• Oxlab guys shown their work on Android and how you can hibernate BeagleBoard
• ST-Ericsson guys presented Snowball boards — we had a talk on some hardware details
• Konstantinos Margaritis shown what kind of difference can be between armel and armhf ports on same hardware
• Angus Ainslie presented Samsung developer board and we had interesting discussion about it

I do not remember all presentations — those ones interested me most. ARM one was amazing — huge FPGAs which were able to emulate A15, A5, A9 just by booting with different MicroSD card… And it is not related only to CPU emulation cause there were two expansion slots on mainboard so FPGAs can became graphics card with Mali core flashed into. Second board was ‘simple’ A9 with Mali and some OpenGL(ES) demo was running there.

And again — new faces to join with names. Talked with Ash Charles about discussions in past when I helped Gumstix developers with OpenEmbedded, Angus Ainslie from ST-Ericsson was working for Openmoko at time when we had cooperation and so on…

Wednesday

Woke up early… What to do after 6:10? Go swimming! So I went to Royal SPA and spent some time in swimming pool and sauna so day started nicely.

Sessions:

• automated cross-buildd system/service
• Ubuntu LEB Star Rating documentation — my session again on how we want to rate level of support of member boards
• ARM Linus interface 3 — attended just to check how kernel developers are discussing how to improve arch/arm/ situation

Met Mark Brown with whom I was working in OpenEmbedded project and after lunch I went to do some sight seeing with Pawe? Moll. Budapest is nice city and I have to came back here one day.

Team dinner somewhere in the city was quite good. We had a fun going back to hotel when ~half of us used phones to navigate though city ;D

Thursday

Sessions:

• arm and other archs certification program — Canonical has certification program of machines which came with Ubuntu pre-installed. I have to check at their tools.
• ALIP mini-distro and build system user/developer stories — interesting discussion
• cross-toolchains for the ARM hard-float ABI — will have to provide them for Ubuntu and other but it is doable
• next steps with multiarch in Ubuntu — where do we go and how

Evening was sight seeing with local guides. We saw parlament building, chain bridge, castle area and ended in interesting pub.

Friday

Ending day and nearly no sessions today:

• port to the ARM hard-float ABI — Ubuntu armhf someone?
• Linaro Review of LDS week
• easier access to -dbgsym packages

Some of people already packed and left, rest will go to have fun at UDS party.

Summary

It was my third UDS and I feel that it was best one. I had two blueprints to handle and both had great discussions which ended in many notes and work items. There was lot of people both from Ubuntu community and Linaro teams. I met many developers, some old friends, went to so many sessions that it took me most of time (I do not remember is list in post is complete).

It was nice to see amount of ARM netbooks at people hands — mostly Genesi Smartbooks but also several Toshiba AC100 ones. I think that it shows that times are changing and who knows… maybe at next event I will not use my ASUS UL30A laptop.

And this is another UDS with some added hardware. This time it is Pandaboard A1 which can replace my EA1 at my work for Linaro. Probably will keep both running one to another but one (EA1) with Ubuntu and second (A1) will be used for misc tests.

Now it is a time to drop laptop in hotel room and go for party!!!

2. Trips in 2011
3. UDS-N: Monday

There is one good thing in 2011 year — I know when I will have to travel for company meetings and which conferences I will have to forget due to this…

So in May I will attend Ubuntu Developer Summit which is a place where we discuss what we want to have done in next release. Event is also known as Linaro@UDS-O cause Linaro people will be there for same reason. Location: Budapest, Hungary. Time: 9-13 May 2011.

Then there will be Ubuntu Platform Sprint which I may be attending but this was not yet decided. This event is Canonical internal and this time will be without Linaro people (which were present on two previous ones). Location: Dublin, Ireland. Time: 27th June – 1st July 2011.

As Linaro has grown we got own sprint — Linaro Platform Sprint where we will work for a week in one place instead of being spread all over the world. Location: near Cambridge, UK. Time: 1-5 August 2011.

And finally another Ubuntu Developer Summit will take place (again) in Orlando, Florida. This will be more interesting UDS because 12.04 will be LTS so more discussions about long term things will probably take place. Location: Orlando, Florida. Time: 24-28 October 2011.

So this year no LinuxTag for me (UDS-O time), no ELC-E (UDS-P). I was thinking about attending Desktop Summit in Berlin but I lost faith in both GNOME and KDE so looks like there is no sense in going there. Will have a look to be somewhere and meet some people from outside of Ubuntu and Linaro worlds.

3. UDS-O

When I was in USA for first time it was UDS-N in Orlando. Previous week it was Ubuntu/Linaro rally in Dallas.

In Orlando I had a problem with waking up very early (like ~4:00) but on return flight I slept for most of flight so in Frankfurt it was early morning for me and I was not sleepy. Next days were also fine.

But this time it is other way ;( In Dallas I also was waking up early but after drinking some water I was able to get back to sleep. Return flight was disaster… There were few small children crying for most of time and I forgot to take ear plugs ;(

Yesterday I nearly felt to keyboard after 15:00, today I am yawning since about same time… Argh you jetlag!

At 4:30 had to get up and ~hour later I was in a bus to Berlin Tegel (TXL) airport. Arrived, met few people from Canonical, got first coffee. Lufthansa did not has so much luck with 10s as Ubuntu did so our flight moved from 10:10 by about hour. Reason was bad weather and traffic jam over Frankfurt airport.

But finally plane landed there and trip though terminal began. After few minutes I heard that passengers to Orlando should hurry so I did. Just to wait insane amount of time in shuttle bus and then in a plane… Good part of flight was that there were many free seats so we (zyga and me) were able to seat next to each other.

But long flights are boring… Lufthansa on board entertainment system uses wrong calibrated touch screens with very long reaction time. There were few good movies to choose but seating after the jet engine does not make it comfortable due to amount of background noise. On return trip I will test headphones from Nokia N900 as they should isolate more then Lufthansa ones (or ones which I use with laptop).

Arrived in Orlando with about 40 minutes delay. Acceptable I think. Customs queue was huge and I did not track how much time we wasted there but everything went fine. We met few other people and took a taxi to hotel. American seat belts are strange – I prefer European way of mounting them instead of “let it hang from ceiling” which is used here.

Met more people in hotel, got “all american burger” for dinner (was quite good) and went to sleep. Timezones difference kills — I woke up at 3:30 and could not get to sleep again ;(

This week I spent in the Hildon Old Town hotel in Prague as Ubuntu Platform Sprint took place there. Linaro project was part of it.

It was good time. I met many developers, connected faces to nick names (as usual) and wrote some patches. Today it looks like my work items for Maverick alpha3 release are “done” — all changes are reported as bugs, linked to my “cross compiler packages” blueprint and discussed with proper developers. The goal of my work is “armel cross compiler” package in Ubuntu Maverick. I know that there are people in team which will make use of it when it becomes available.

But for next event I really need to take isolating headphones as there are too much noise in room — few groups of people speaking, air condition etc.

Evening events were interesting — I met Czech developers from OpenEmbedded project, had occasion to listen to Nicolas’s Pitre stories about his developer experience and long discussions on many different subjects. And of course Czech beers ;) Too bad that main one here is Pilsner Urquell as I can buy it in any local shop in Szczecin. But they also had Staropromen which was quite ok.

Prague is nice city. I did not made lot of sight-seeing but this weekend I will spend with my wife Ania so it will be done ;D We plan to see some of popular places and try to find those less popular ones but due to time limits there will be some left for next visit.
