21:40:37 # Life Trying to chroot from a non-debian userland on linux kernel. I was playing with this ARM environment. When there is no chroot command outside the chroot, and it's running incompatible libc, I could try running chroot command inside the chroot with: LD_LIBRARY_PATH=./lib:./usr/lib ./lib/ld-2.9.so ./usr/sbin/chroot . Using ld.so inside the chroot to load the chroot binary inside the chroot, and setting LD_LIBRARY_PATH to point to inside the chroot so that ld.so can find the libc.

23:53:19 # Life mecab package for Debian. In Japanese, words in sentence are not split by spaces, and are written continuously. Thismakesparsingofsentencesverydifficultformachines. Luckily people have done much research, and probabilistically split words in sentences. That science is apparently called morphology. There are some packages in Debian; ones I know include chasen, kakasi, and mecab. I looked at mecab today. mecab has different dictionaries, and there are 4 dictionaries in Debian lenny. One free one (mecab-juman) and non-free one (mecab-ipadic). This looks confusing for first-timers.
