Over month ago OVH started offering “KS 2G” servers for 15 PLN per month. Like few other friends I decided to take it.

Waiting for new machine took nearly a month but finally got it. I had a small problem with a name for it. But as “KS 2G” is smaller than i5 where my previous system was hosted I decided to reuse name “malenstwo” (Roo from “Winnie the Pooh”) which before was attached to PandaBoard(s).

Copied data from previous server (named tygrysek due to Tiger), updated Ubuntu to 13.04 and started to migrate services. And today I moved last one and sent my Xen VM instance to shredder…

What changed? I have “bare metal” machine on which I can do experiments and do not have to worry about users of other Xen instances like it was before. Have native IPv6 address so sending backups to my home will be easier.

This time I took two weeks for trip to my family. We visited Olecko and surrounding cities.

On second day I  got several email from Niantic with accepted/rejected information about portals I submitted around one month earlier. And the number of those in Olecko went from 3 to 13 ;-)

But Ingress was taking just very small amount of time as there were better things to do. Visiting family, meeting friends, showing interesting places to my daughter etc.

But one day some L8 players arrived in neighbourhood. So after some chatting we agreed on making some fields to show local Resistance players that green is nicer colour :-D

There were few players involved: @marecki007 @qringo @radmus @szelka and me. We also helped @Buzka to get from L2 to L4 so he will be able to keep local portals green for longer.

Today map:

There was also control field Ełk - Augustów - Suwałki but it was destroyed twice by local Resistance player.

I think that end result is nice especially as it was not planned before.

Now when mainline kernel boots fine on Samsung ARM Chromebook I think that it is a time for me to end my work on Ubuntu support for this device.

Those few who use Ubuntu 13.04 or later: nothing will change for you probably. Kernel from repository is old and should be refreshed to at least same as Chrome OS is using. But during last few months no one tried to get it working so for me it looks like lack of interest.

Anyway I will need development machine for my work at Red Hat. So soon Ubuntu 13.10 gets replaced with Fedora 19 “remix” with 3.4 or 3.8 kernel first probably (for USB 3.0 and audio) and then sooner or later switch to mainline.

On behalf of Gary Lamb and Tyler Šiprová, I would like to welcome you to Red Hat. We are thrilled to have you as part of the team!

Starting from 1st September ;D

Yesterday was my birthday. I would not write about it but something happened…

It was just kind of normal day. I went to the city centre to gain some AP in Ingress, met with courier to pick up my new power bank (10000mAh Anker), played again and then got back home to prepare for evening meeting.

It had to be just yet another beer meeting with some geek discussions as we had some changes in local Unix/Linux user group. But then (after 3rd bottle of beer) waitress brought us something:

The team started signing etc. I was surprised as I did not expected anything like this. And it was delicious! Kudos to Kruszynka for making it.

Olof Johannson wrote on Google+ how to get mainline kernel booting on Samsung ARM Chromebook. As mine returned from repair with new speakers and bottom cover I decided to take a look.

With chainloaded U-Boot and just standard “exynos_defconfig” build of 3.11-rc2 I got my machine booting to Ubuntu right away:

00:06 hrw@krolik:~$ cat /proc/device-tree/model ;echo
Google Snow
00:06 hrw@krolik:~$ uname -snrp
Linux krolik 3.11.0-rc2 armv7l

There are some things missing (audio, usb 3.0, backlight and more) but even with what is available we can boot and use Chromebook with mainline kernel instead of ChromeOS one.

I will revert to 3.4-chromeos for now and try 3.8-chromeos one but that’s because I use Chromebook as developer machine for some builds where storage speed matters.

Months ago a new game started: Ingress. There is a story behind it but not that I care about it.

In short: there are two teams: green (Enlightenment) and blue (Resistance) trying to take over the world by “hacking portals”. Sure, someone could say that there are many MMORPG games on a market already and they would be right. But there are few things which made me play Ingress.

1. To play you have to get your ass moved as game takes place in so-called “real world”. You know — streets with people, cars etc.
2. Gives possibility to learn many more or less interesting places around.
3. Another opportunity to meet other people and have something common to talk about.

For me it started 4 weeks ago when I had three spare hours during Sunday evening. Joined the Enlightenment and hacked some portals in Warsaw, made few links and ended with a bit above 10k AP which gave me 2nd level. Next evening (in Szczecin) I met some local players and they helped me to get to 3rd one.

Then time went… I convinced a friend to play and helped him to do L3 in one evening :D And during last weekend I was in Warsaw again and made 7th level (with help from local people who told me where to go to get some AP in quick and easy way).

But what I like most is a need to grab a bike (or take a walk) and go to city centre to spend some time in active way ;)

As I left Linaro I am not at Linaro Connect in Dublin, Ireland. But decided to access at least keynotes (which were always interesting) and probably also some sessions.

George Grey introduction speech was fine. Number, standard Linaro information (what it is, how many people etc). Worth watching if you want some updates but may be skipped.

Then James Bottomley from Parallels spoke about server side of computing. Unix, Windows NT, Linux, Itanium, AMD64/x86-64, Atom, 64-bit ARM are good keywords for his presentation. I liked few things:

• Itanium iceberg description (why IA64 was disaster without IA32 compatibility)
• Atom contra ARM “power fight” (hard to tell which one will be better for servers when it comes to energy use)
• mentioning of Blackadder (I know what it is but never watched more then one episode)

There were some issues with bandwidth so there are few moments in video where audio/video stops and you get group photo from previous Linaro Connect instead. But this is “normal” on first day and I hope that will get fixed by network team.

There are few sessions today which I plan to take a look. ARMv8 Status one and the one about Linux scheduler.
