Haskell GTK on 64 bit MacOS X
View gist:2420144

Notes

  • on lion (and snow leopard i suppose), make sure you are using a 64 bit install of ghc. Also, unless you are suggesting an edit to these directions, please go ask people on the relevant mailing list or wiki for help :)
  • Tested on ghc 7.2.2, assumes you have standard developer things installed on mac, like x11 and stuff
  • Also tested on GHC 7.0.4 (Haskell Platform) with XCode 4.3.
  • These notes were originally brought to you by Carter Schonwald; the “I” probably refers to him. Eric Kow will refer to himself in the third person).

GHC 7.4.x

  • gtk2hs 0.12.2 won't build with ghc 7.4.1, but the current darcs repo for gtk2hs does build

The Common Project Project (version 0.1)
View common-project.md

A country that's polarized is paralyzed. If we want any change in the coming years, we need to find a way to work together. However, you can't just unify people by holding hands and singing Kumbaya. No – rather than ignore or "put aside" our differences, let's use our different perspectives & interests & skills to tackle problems from all possible angles! For us to find common ground, we first need to find common goals.

This is the Common Project project.

Below, you'll find a list of projects, people, organizations, books, talks, movies, articles, and ideas that cross partisan lines to solve The Big Problems we face today. There's many such problems. And we'll need help from all sides.

Advice on benchmarking databases
View gist:0ad3458a1478db97517e7ac2faf2da00
Hi S-------. I'm not an expert in performance benchmarking--I focus on
correctness and safety--but I have a few pieces of advice here.
0. Pick multiple workloads that cover the gamut of behaviors in each DB.
*Don't* choose a completely sharded workload for VoltDB. Don't choose a
purely commutative workload for Cassandra. Cassandra's Paxos
implementation is slow and a good benchmark will demonstrate
that--however, it *doesn't* (I think?) require a global coordinator,
which means it might *scale* better than a single-coordinator system
like, say, VoltDB. Talk about those differences!
You can’t perform that action at this time.
