My "small" project for Saturday... reupholstering my £60 eBay purchase...
This was the disgusting state and the reason I paid £60 for 6 chairs and a table.

Brand new foams.... set of 6 was £46 including p&p
Here you will need staple gun. ...
I bought this one:
200 staples later...
Final effect:

JBoss clustering...
So... I had to set up cluster on JBoss to use it as a load balancer for data loading.
I had a problem with deployment of test and production servers.
If you have several servers pointing to different databases and running different versions of application then it's not that great if you are using the same partition configuration setup.
The solution is to deploy each server with different partition name. Without it "master-node" will schedule jobs on all known nodes in the same partition which means it won't load data into one database but to all of them - and this obviously isn't our goal :)

Time for new working rig...
For some time I'm thinking about buying new computer. Mainly because I've built the old one in 2007 and I feel that over 5 years for a computer is enough. In my mind it's old and doesn't perform as it should... but...
There's always some "but" :)
The old machine is powered by Intel Core 2 Quad Q6700 2.66GHz processor which is running flawlessly overclocked to 3.55GHz (no voltage increase needed). It has 8GB of performance RAM from Corsair (Dominator 1066MHz 5-5-5-15) and quite good motherboard from ASUS (P5E).
The best part of the setup is RAID-10 array. 4 Seagate 500GB discs are running for all of these years with speed comparable to low-end SSD drives.
Volume 1:
Volume 2:
As you can see the first volume (closer to the edge of the spinning discs) is faster than the second one and on average performs with amazing speed of 177 MB/s. Second volume is obviously slower but still performs with average result of 131 MB/s.
I was planing to buy something new, probably:
- i7 3770K
- Asrock Z77 OC Formula or Asus Z77 Sabertooth
- GSkill 16GB 2600MHz
- Ati Radeon HD 7950
- 4 x 120GB SSD (to run them in RAID 10) - you might think this would be an overkill but believe me, even in XXI century in middle of London, UK we have power outages at least once in couple of months. 99% of them last for few seconds but it is still enough to corrupt your data and make you angry! :)
I'll have to rethink this whole thing.
ps YES I know that SSD is still much faster because of the access time :)
