Uncontrollable phenomena are frequently renamed to create the impression of control.

I should say "exchange of land and military service"; the point being that economic activity became less liquid and harder to tax, hence harder to centralize power.

Enjoyed the 22 lectures of Paul Freedman's "The Early Middle Ages, 284–1000", Open Yale Courses. Fascinating to see a "radical simplification of economic life" when a central government (backed by a unified army paid for by imperial tax revenues) is replaced with local power structures, mediated by exchange of goods and military service. No wonder governments are worried about the taxability of cryptocurrencies. Interesting to see heresies as a threat to political unity. https://oyc.yale.edu/history/hist-210

tcpserver is a nice little tool to quickly serve some data. It's like netcat or socat but you can accept connections from multiple clients. For example if you want to stream out log data to anyone who's interested you can just do

$ tcpserver 0.0.0.0 9999 'tail -f data.log'

and all your clients can read it with

$ socat $SERVER_IP 9999

I guess if you wanted anything fancier you'd have to use a message queue.

Fun #haskell projects at this weekend's #hackathon in #sf including karya: a 2D music language, and gelatin: a real-time 2D graphics API https://wiki.haskell.org/BayHac2018

Enjoying Patterson & Waterman's "#RISCV Reader" . It's cool to see the architectural advantages over x86-32 and ARM-32. Example: arithmetic operations for bytes and half-words are a waste of silicon. Instead, use byte and half-word memory loads, then sign-extend the result to a 32-bit register and use word arithemetic. The performance benefits of narrow-width memory access overshadow special narrow-width arithmetic operations by orders of magnitude.

@vertigo Good to see you at SVFIG - a few local folks are interested in a #RISCV hack night/day in the near future if you want to hang out
