I started my IT career in 2000 when I could do only shell, make, and Perl. After working on a few easy not-really-development projects, I changed jobs and devoted time to work on kernel side development. I brought up a few PowerPC boards with U-Boot and Linux. Some of them had InfiniBand interconnects for parallel computing. Unfortunately this product was too ambitious to be released at that time. I learned everything by myself there.
Then I worked for Brains, which is best known as mmEye, then IIJ SEIL team. Both of these use NetBSD for their products. Luckily I could work on new NetBSD based products. Later I made my own company, of course which uses NetBSD. This way I've work...
