I am running my blog for nearly 12 years now. And through all those years it was running same WordPress installation. Until today.
At beginning it was WordPress MultiUser (WPMU) as I used it to run both my blog and website for my consulting company. It was fun. Some WP plugins were working with WPMU, some not. Then WordPress developers decided to merge both projects into one. And it was good.
When I started blogging I did not used categories for posts but tagged them instead. Months turned into years and at some moment WP got tags natively so UltimateTagWarrior plugin went to trash (after converting to WP tags).
I was changing blog theme every few years to bring some change. The other thing which was changing was http server - from Apache to Lighttpd and now it is powered by Nginx + PHP-fpm.
Company website got trashed in meantime. Our wedding page appeared for few months as other blog. There was map with all required placemarks for church, flower shops, family homes, hotels and other useful services. Wish list for those who wanted to know what to give was also present. With “sepulki” as last entry — no one knows what “sepulki” are as they appear in one of Lem’s books. The only known thing is that you need to be married to be allowed to use them. Some guests had interesting ideas for it ;D
At some moment I had a page with Mira’s photos. Page required registration and logging. Long time removed.
And then Ania (my wife) requested page for her psychotherapist services. So she got it.
At some moment I was running three different domains using one WP installation. It was mess. Terrible mess. At some moment there were authorization issues so I had to change something…
So now I have fresh WordPress installed. Websites partially restored from backup to not keep settings/tables from long time not used plugins. Hope it will work fine ;D
May came. I went to UK to visit Bletchley Park. Awesome place to visit. And right next to it is The National Museum Of Computing (TNMOC in short).
Inside there is history. I mean HISTORY.
By mistake I entered museum through wrong door and started from oldest exhibition. It was showing the story of breaking Lorentz code used by Germany during second world war. And hardware designed for it. Contrary to Enigma there was no Lorentz machines in Allies possession.

Rebuild of Heath Robinson machine:

Next to it was room with working replica of first computer: Colossus.
Colossus
And here you can see it running:
There were several other computers of course. I saw ICL 2900 system, several Elliotts and PDP systems, some IBM machines and others from 50-70s.
One of them was Harwell Dekatron Computer (also known as WITCH). It is oldest working computer:
Harwell Dekatron Computer
Then there was wide selection of microcomputers from 80s and 90s. Several British ones and others from anywhere else. There was a shelf with Tube extensions for BBC Micro but it lacked ARM1 one:
This museum was on my list for far too long. When I was in Cambridge few years ago it was closed. Next time I did not managed to find time to go there. Finally, during last Linaro sprint, we agreed that we have to go there and we went during lunch break.
For me the main reason of going there was my wish to see ARM1 cpu. It was available only as Tube (extension board for BBC Micro) and only for some selected companies which makes it quite rare.
ARM1 Tube
The first thing I saw after entering museum was “Macroprocesor”. Imagine CPU in size of 70s mainframe with LED on each line, register bit etc.
Macroprocesor
Next room was arranged in a form of British classroom. Set of BBC Micro computers arranged with monitors, manuals, programs.
BBC Micro equipped classroom
And then I went to look around. There were many different computers shown. Some behind glass, some turned on with possibility to play with them (or on them). It was opportunity to see how design was changing through all those years.
AES 7100 Model 203
There were also several Acorn machines — both ARM and 6502 powered ones.
Acorn Archimedes machines
As most of computer museums that one also has some exclusive content. This time it was NeXT workstation which was used as first web server by Tim Berners-Lee:
NeXT workstation
And Apple Macintosh SE 30 owned by Douglas Adams, author of “Hitchhiker Guide to the Galaxy”. Note a towel on top of computer:
Apple Macintosh SE 30 owned by Douglas Adams
Other interesting thing was comparison of storage density through all those years. Note 5MB hard drive being loaded into plane in top right corner.
Nokia. A company everyone knows and most of us probably even used one of their phones in past. They were better or worse but one thing was good - most of them shared batteries…
My daughter (8.5y old) uses Nokia E50 as her daily phone. Sim card is covered by duct tape to not fall out when phone hit a floor (previous one went missing in such situation). Mira records how she and her friends sing, does some photo sessions to her dolls etc.
But during weekend phone stopped charging. Hm… Is it charger? Nope, it was original Nokia one. Tried some crappy Chinese one with same result. So let’s check the battery.
Opened drawer, took Nokia 101. Inside was BL-5CB battery. Inserted into E50 got phone back online. But I like my 101 and keep it as a spare just in case.
Digged in a drawer with old devices. The one where I keep Sharp Zaurus c760, Sony Ericsson k750i, Openmoko FIC-GTA01bv3 and few other pieces of junk with some sentimental value. What I found there was Nokia 6230i which I got from Ross Burton during GUADEC 2007. Last time I used it about 5 years ago. But it had original Nokia BL-5C inside!
So I put that battery inside of E50, plugged charger and guess what… It started charging and phone booted! With over 11 years old battery!
During next few days I will buy BL-5C clone somewhere (they are 3-8€ now) and put it in my daughter’s phone.
Few months ago I created a page with HTML table. For own use basically. Then presented it to the people and found out that it got useful for them. So started improving and improving so it became side project.
Yes, system calls again. I wrote about it in past but yesterday I rewrote code so it now uses Linux source so I can generate tables for far more architectures without need of other computers (either real or emulated).
Next step was work on presentation layer. Old version was just table with added sorting. Things were ugly when scrolled as header was gone. Now it sticks to the top of page so it is easier to note which column relates to which architecture.
Odd/even lines are coloured now which makes is easier to find numbers for syscall.
And speaking of searching — there is filter box now. You can type syscall name (or part of it) there and have table filtered. Same can be done with system call number as well. You used Valgrind and it said that has no idea how to handle syscall 145? Just enter number and you see that it is getresuid(), nfsservctl(), readv(), sched_getscheduler(), setreuid() or setrlimit() — depends which architecture you are testing.
You wonder what that that system call does? There are links to man pages provided.
Before going for Linaro Connect I had a plan to look at all those 96boards devices and write some complains/opinions about them. But it would be like shooting fish in a barrel so I decided against. But there were some interesting pieces of hardware there.
One of them was Macchiatobin board from SolidRun. I think that this is same as their Armada 8040 community board but after design changes. Standard Mini-ITX format, quad core Cortex-A72 cpu (with upto 2GHz clock), one normal DIMM slot (max 16GB, ships with 4GB), three Serial-ATA ports, PCI-Express x4 slot, one USB 3.0 port, microSD slot.
UPDATE: SolidRun confirmed - this is final design of their Armada 8040 community board.
Photo (done by Riku Voipio) shows which goodies are available:
Armada 8040 community board
Network interfaces from top to bottom are (if I remember correctly):
10GbE (SFP + RJ-45)
10GbE (SFP + RJ-45)
2.5GbE (SFP)
1GbE (RJ-45)
When it comes to software I was told that board is SBSA compliant so any normal distribution should work. Kernel, bootloaders (U-Boot and UEFI) are mainlined.
Price? 350USD. Looks like nice candidate for AArch64 development platform or NAS.
Other device was Gumstix Nodana 96BCE board which is 96boards compliant carrierboard for Intel Joule modules.
On top it looks like typical 96boards device (except USB C port):
This is first non-ARM based 96boards device. Maybe even one of most compliant ones. At least from software perspective because when it comes to hardware then module makes it a bit too thick to fit in 96boards CE specification limits.
Note that 96boards Consumer Electronics specification does not require using ARM or AArch64 cpu.
One of cool things of being Linaro assignee is going to Linaro Connect conference. This time it was Las Vegas, USA. I was flying Berlin Tegel -> London Heathrow -> Las Vegas. Last part was fun as I met several Linaro folks at the airport ;D
Arrived in Vegas, went to hotel and fall asleep. Sunday was planned for some Ingress playing and for sightseeing. As usual I had several places marked on Google Maps to make things easier.
So Sunday… It was really Sun day. I took some water with me and refueled several times during day just to stay hydrated. With Las Vegas climate I was not even felt sweety as it vaporated right away…
Street with palm trees
But let’s start from beginning. I walked few hundred meters from hotel and caught public transport bus which took me to Freemont Street (or somewhere around). When I walked I felt like the only person on the Earth or in a no-go zone. There was basically no one on the street. After some walking and few photos I got asked something like “who are you and what you are doing here???” from security guy. It turned out that some part of Freemont Street (and surroundings) were closed due to some arts/music festival. I probably missed some ‘no entry’ plate…
Atomic liquor
Anyway I did not get any problems and was pointed where the gate is. Walked around, saw some places, bought souvenirs (including fridge magnet to my collection), another water bottles and decided to walk to another point on my map.
Yes, it may feel strange but I walked. And walked. And walked. Then Arts district happened.
OMG it was awesome. Deserted streets, shops with some retro furniture/stuff, shops with some crazy junk, shop with wax figures from Last Supper etc. But the best part was murals and graffitis. Lot of them, different styles and quality. I spent about 2 hours just walking there and taking photos.
Hydro geek graffitiStagecoach made from metalWoman graffiti
Next step was the Strip. All those big hotel/casino buildings. At Circus Circus I found room with arcade machines and spent 25 cents on Galaga. In Venetian I looked at their version of Venice canals (have to go to Venice and compare one day :D). Few minutes later I saw Eiffel tower (or rather miniature version of it). Decided to skip searching for copy of Statue of Liberty and instead crossed street and went to take a look at Bellagio fountains show. Have to admit that it was nice. I saw three shows (had to sort few things around) and then took a cab back to the hotel.
One of things you do while you are at Linaro is going to Linaro Connect conferences. My previous one was 2012 Copenhagen one so it was good to be back.
All those people from different companies or projects… Some faces I recognized, some not. Several people recognized me, some said that my beard complicated it. Fun ;D
Discussions about random things, random hacking (not all Snow chromebooks are the same), talks to attend, talks to give…
And speaking of speaking — our team had a speak about OpenStack on AArch64. It was recorded but volume level is very low.
Complaining. Sure, there was some. And I got my badge upgraded just to show all those impersonators that I am back.
badge with the main complainer text on it
There was jetlag as usual so I was a bit of excluded from evening events but those which I attended were great. Like team dinner with the Big Kahuna cheeseburger (with Sprite to drink).
Next year I have to organize trip in a way that I would do some personal sightseeing on a week before conference. According to rumours it would be in one of areas where I have some places to visit ;D
Time to downgrade my main desktop finally came. This time I decided to provide more details about process as my system uses Rawhide with set of external repositories (RPM Fusion (official + my rebuilds), few COPR ones etc).
So first step is to enable caching because dnf by default erases all downloaded packages. And downgrade involves fetching many of them. Edit ‘/etc/dnf/dnf.conf’ file and add “keepcache=1” line there.
First try:

As you see there is set of blockers. One of them is “ffmpeg-libs” from RPM Fusion, others are from normal Fedora repositories. One of reasons can be that packages got split/renamed since F24. Let’s try to handle some of them:

Last blocker is “perl-libintl-perl” package. In F24 it was named “perl-libintl” so dnf is not able to handle downgrading. Simplest way is removal of it. Will install removed packages later.

file /usr/lib64/liblua-5.3.so from install of lua-5.3.3-2.fc24.x86_64 conflicts with file from package lua-libs-5.3.3-3.fc25.x86_64
This is less fun… RPM needs Lua to work. So I went around. Unpacked Lua package from F24, then “rpm -e —nodeps lua-libs” and copied “lib64” from just unpacked package directly into system. Then downgraded “lua” using dnf.
Next step? Distro sync of course. This time it works. Now kernel needs to be taken care of.
I had 4.6.0 kernel installed from I have no idea when. Booted it and it allowed me to remove all “4.8-rc” kernels I got from rawhide. Then simple “dnf install kernel” to get 4.7.2 from updates repo and after one more reboot I got:
As you see it took far more time than I expected it will. I learnt that ‘keepcache’ is not enabled (had to fetch 2GB of packages again), found ‘minrate’ dnf config option which helps me avoid slow Austrian mirror.
