Original plan for the Montréal REM Côte de Liesse station with the passengers going below tracks to cross them. Actual station has passengers going over tracks.

On the other hand, i had a good visit to my ENT who extracted large amounts of ear wax that was stuck. TMI But that’s the most exciting thing that happened for me so far in 2026.

Here, have some huge BC trees:

Looking straight up at a canopy of extremely tall fir trees. There's a really neat pattern of similar size gaps between adjacent tree tops, and the bright white cloudy sky peeking through the gaps.

It feels SO SO GOOD to move my homework code and crappy experimental repos to my own forgejo git server! Most of the stuff is for learning so it's super crappy, but it's my super crappy code.

A windy day, but with excellent visibility, on Angelus Peak, this past Sunday. #NelsonLakes That was the first time I climbed it on this trip, but not the last! #Aotearoa

Angelus Lake prominent in the centre of this photo on a pretty windy, partly cloudy day with lots of sunshine. Mountains abound. There is a hut which you can barely see on the shores of the lake.

Oh no my gingerbread christmoose has suffered a grievous injury

A gingerbread moose in a red cardboard sleeve with a clear cellophane front. One antler and the front leg have snapped off cleanly, condemning this poor moose to the fate of being rapidly devoured by local predators (me and Katie).

Home HPC back of the envelope figuring: around $1250 CAD gets me a decent compute node. Threadripper 2920 to 2050, 48-64g ram, 8TB U2 nvme SSD, a good case with PSU, Intel Arc card for DIY gpgpu, and a 25gbps network interface card.

Spent a while working on this one. It's a music visualizer using a 10x10 grid of cubes. I tried a lot of different approaches to get this working. It uses Python with librosa to do the audio analysis, using STFT to pull per-frequency amplitudes. My first approach was to use a driver-driven […]

Best damn wiring job I've ever seen. Puts my server room in Toronto to shame. Mare Nostrum 5 supercomputer, 14th on the Top500 2025 list #marenostrum5 #barcelonasupercomputingcenter www.bsc.es/marenostrum/marenostrum-5

Barcelona Supercomputing Centre - MareNostrum5 - showing storage nodes in server cabinets. Colour coded wiring - blue for Storage node, Red for computation node, yellow for networking (if I remember correctly)

MareNostrum5 supercomputer - server cabinets, cooling nodes, all arranged in rows and columns.

Super Large watercooling pipes and pumps. Colour coded, red probably means hot, green is the intake. Doesn't need "cool" water - just need a small differential to pull heat - so I think the loop is actually pretty hot (a little lower than cpu temp)

I sound like a crazy person to myself, but I'm going into a deep dive into HPC, slurm, lustre, RoCE/Infiniband. I don't know where this is going to go, but I'm probably going to end up with way too many computers and way too many switches.

While we wait, the internet needs some happy animal vibes, so here's a cat in a basket, and my herd happily eating new grass (it's been super dry, until it rained like crazy the last 2 days, so there will be a bit more grass before winter hides all of it).

A grey cat smugly curled up in a woven willow basket that's just the perfect size for him to fit into. The basket is sitting on a table.

A whole bunch of white, brown, and black goats happily eating grass and weeds in a big pen, along with a small brown horse and a couple of comfortable looking fluffy dogs. There is a wooden farm fence in the background and the sky above is blue.
