What is this I don't even..
From the BBC about Fukushima: The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 millisieverts an hour.
However, the company said the equipment used to make that recording could only read measurements of up to 100 millisieverts.
The new recording, using a more sensitive device, ( Read more... ) -
EventMachine
This is probably only of interest to perhaps three of you, but what the heck.
I discovered today that EventMachine, a very commonly used Ruby library, has a completely broken popen implementation. Specifically, it doesn't ever call waitpid unless you are- Running on Linux and have selected the epoll option
- or the process closes all of its input ( Read more... )

Unix arcana
Fun fact: the checksum size computed for tar archives is 16 bytes long. This is not documented anywhere.

Photography
I've been finally (after around two years) getting around to developing some of my backlog of film, while waiting impatiently for my blackout cloth to arrive so that I can actually have a darkroom. It is amusing in some ways to contrast my two main hobbies these days; long obsolete Nikon lenses that won't work on most current bodies are still $300 ( Read more... ) -
Teamwork
It's weird working on something as part of a team, or especially as something someone else wants done but where the spec is a little bit different every day. They're good about it, it's not the usual spec hell stuff, but it can be very disorienting to come in and discover someone has e.g. decided your internal structures should really look like Y ( Read more... ) -
New toys
My iPad arrived today, when I was home sick due to weird intestinal problems (the less spoken of, the better). Man, there is no surer way to make an iPhone look tiny than to compare it to Big Brother here ( Read more... ) -

Graham's evening: a play in one act
GRAHAM: Phone? Phone? Wake up, I want to play games. PHONE: *iz ded* GRAHAM: Bollocks. Out of batteries. *unpacks computer* Power? Power? Where are you? POWER: *iz hiding* GRAHAM: Oh, there you are. POWER: *panicks and cowers in a narrow space smaller than Graham's arm* GRAHAM: Fuck. *scrapes up arm getting power plug in* *spends hour sorting ( Read more... ) -

Interesting CS problem
I've come across a rather interesting CS problem during work that I thought I'd throw out there. The problem is this: given a finite lattice (L, ⊑) (our problem has a lattice that is also distributive, so you may presume that) and a node x in that lattice, efficiently compute the set S ⊆ L = { y ∈ L : x ⊏ y ∧ ∄ z x ⊏ z ⊏ y }. This is well defined ( Read more... )
