I really like geek T-Shirts! Actually we saw a lot of creativity on it, carpets (who don't know about the '127.0.0.1' ;-), cups and etc. I think these kind of stuffs are really cool to spread the word, and that plays a crucial job on Open Source projects. So, ...

Ok, that was funny... well, not really, because i did loose a lot of time on it. I have no experience with ASM (Automatic Storage Management) by Oracle, and while a system administrator, i did manage the oracle volumes as filesystems. The raw devices on that time had the 'performance' ...

Hello there... As many of you already know, a new version of Solaris Operating System is available: Solaris 11 Express. Seems like the Solaris 11 will be released next year, but i really don't know if that is the case neither the diff between Solaris 11 Express and Solaris 11. From what ...

That was a simple but nice one... i did see a huge write performance on one of our storages. Take a look at this slog device (SSD): r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 10494.5 ...

Maybe if i could understand the Oracle's mind, i could learn how to make money. I think that is the key in this whole Oracle/Sun situation: Java, Dtrace 1, 2, 3, 4, and ZFS creators did leave the company. Why someone would buy a technology company, with so many ...
