Early this month I was reading Cliff Stoll’s The Cuckoo’s egg, it’s about how he hunt a Soviet hacker in the 1980s. During his investigation, by then the NCSC chief scientist Bob Morris asked a question for him: what’s the next number of the sequence 1, 11, 21, 1211, 111221?

I happened to find that a nine digits .xyz domain only cost $0.98 a year by viewing Wikipedia last week, that’s a reasonable price of an untouchable thing and fun. So here we are, the new domain 111211211.xyz will points to this blog at least one year until I feel bored.

Cliff surely is an interesting and passionate guy, watch a few Numberphile videos of him you will agree with me. As of the book, definitely worth the time. You will know how to trace the route to locate a criminal; how a UNIX guru can tell the hacker is not from California by a single command; what Internet was like in the early days and how come a network depends on trust can lead to havoc. You can also sense NSA already collecting data from that time, Snowden’s Permanent Record has more details.

Everyone should wash their hands more frequently now so don’t forget to bring a towel.
