There’s already rumours going on about latest design of Malaysia national football team jerseys. Here they are,
So, I asked Nike whether it’s true. And I received an expected answer,
Apparently Nike Malaysia didn’t deny nor admit, they just said that the official version will only be revealed by them.
Objective
To add 1x100GB & 1x200GB mountpoints to existing GPFS cluster.

Finally, there’s something to do with Malaysian football: Malaysia vs Sri Lanka on 28-April-2012.
At present, ticket can be purchased online at Ticket Hotline. Ticket will also be selling at the stadium on the matchday itself.
This match is recognized by FIFA and will give influence to FIFA ranking, so let’s go to support our team, shall we? Hmm, now I need to plan my attire on the matchday.

Personal comment:
A very rare “khazanah bolasepak Malaysia“, I can’t really recall this jacket to be sold at normal Nike outlets in Malaysia. I’m very glad to have this jacket; I can wear this as stadium jacket during football matches involving Malaysian team and probably wear it as raincoat when I’m riding on my motorbike, hehe.
