After reading some posts on Server Room I’ve decided to do some scrubbing on my zfs pools … just in case ( done it a few times some long time ago )
The I’ve noticed that one pool takes ages to scrub:
state: ONLINE
scrub: scrub in progress for 0h59m, 40.72% done, 1h26m to go
turns out one of the drives is under-performing :

That’s bad, it’s my only Seagate which survived in the box … looks like I will have to start hunting for cheap 1TB hitachi again …

Started doing something with my not so recently acquired domain atticgroup.net installed planet aggregator for all ex attic people who I know.
Boring. It’s boring to try to find out RSS feed addresses for all possible web applications and people, so if you are ex attic and not featured on the page yet, please please send me your RSS address and if you dare, all other whom you know as well.
Creative. oh, and all you creatives out there … design better web template 
Some input will also help…
Yeah, like any of this will ever happen… people don’t care anyway…

I am due PPL skill test for last month… and it’s annoying. If it is not weathers fault, there is no aircraft, if weather and aircraft are nice, examinator decides that he does not want to fly today…
So I have it scheduled for next weekend… but already can see problems as there are other test pencilled in…

RHEL 5.0 on HP G6 Proliant
So, we got a new hardware for testing our product. Great, finally. To make sure that we test as close to what we consider Live, we have produced a system image with all required software pre-installed.
It worked perfectly when we provisioned it on our new dev environment.
However this time, we couldn’t get any more DL360 G5 boxes and had to go with a 6th generation.
Being a bit naive, I thought that HP would be considering but no… they screwed up compatibility between newer SmartArray 410i and slightly older 400i so basically our not so new RedHat didn’t see the new controller.
Simple solution is to install new kernel and drivers. But how? when your system is not bootable.
Well, tried many things but the thing which worked well, was pulling the drives out from new server and sliding them in to G5 which was conveniently laying around. Installing new kernel and drivers and voila! boots on G6. Oh kernel came courtesy of CentOS 5.4 so that version was supported by HP drivers!

It’s a few months since I started my PPL training. I am now on the verge of finishing it and currently I am occupied with passing ground exams which will allow me to take the final skills test.
Now I fly bugger all and only my decision to pursue Night Rating is keeping me at the control, but this will end soon as well.
So, yeah time to finish and get my ass flying on my own license!

It’s amazing. My love for flying and computers is starting to have it’s children.
I’m kinda inventive and lazy guy. When I can automate something, I don’t bother to do it. This is very annoying when I’m flying. Especially annoying when I have to recall some details. Some of these details are … Takeoff and Landing time records.
As an ex. in mastering C++ with QT on Maemo ( and I believe all other QT platforms like Symbian ) I have started developing a small help tool for myself.
At the moment it is dirt simple ( took me 3h to write and test ) , with a touch of a button it records take off time and with another touch of a button, landing time.
It’s usable now, if you wanna try ( just drop a comment ).
I will be adding also recording of this data to a text file, with basic calculations :
- conversion to decimal
- time for pilot logbook
- tech log
So it’s just a beginning for me. And what a fruitful one. I never expected that I still remember that much C++ to scribble something that quickly with unknown API.
