  1. A SciFI book about an inadvertently sentient computer program from 1977. Similar vein to Hartling’s Avogadro books 35 years later. Not bad for the time — owning all the IBM 360s.

  2. Inferences-per-second for different batch sizes on resnet-18 / Titan RTX. Single batch, on-line use is only 3% of peak performance. The last 30% of perf increase all shows as "98% cuda utilization". It is an interesting question to consider what convnet architecture you would \

  3. Visualization of a net learning a 2D image function with four different random start parameters. Interesting how much the character of the init remains after 1200 updates.

  4. It is Quake 3’s 20th Anniversary today. I still have one of the trade show launch props in my garage.

  5. Titan RTX has Cray T90 style.

  6. The Arcade Learning Environment, based on the Stella 2600 emulator, is popular for reinforcement learning work. Probably doesn’t matter for agents, but I am distressed that Stella has four frames of input latency for people.

  7. Visited the Samsung HoloLab yesterday. They can capture 30 fps depth video, but I suggested they should add one extra second of footage with each light alternately strobed on individually to get a good surface BRDF capture as well.

  8. I had assumed the bottom 1x1 mip level of a texture after glGenerateMipmap was a good average of the entire texture. Not so if any of the levels have odd dimensions -- entire rows or columns are skipped. This caused some subtle issues with theater lighting.

  9. Welding sparks are a fantastic demonstration of shutter angle / exposure time. From

  10. Nietzsche on revenge. I found this noteworthy — I am not a very empathetic person, but I also don’t seek revenge, and often don’t even notice slights or disrespect that others comment on. I never considered that it might be related.

    That was weird... I thought it was this

  12. I had a great time talking with today!

    I only intended to play through Hard once before going to Expert, but 😜

  14. Sigh. Comic book (also fantasy art) archery. There was an issue of Mike Grell's Green Arrow that had him inferring the build of an assassin based on the spine of a recovered arrow, but usually the bow is a funny shaped zap gun.

  15. My little bit from the F8 keynote. really was the most important benchmark for tracking, from my point of view!

  16. I know my Beat Saber leader board spots won't last a day from the consumer release, but...

  17. Pitch Dark on my Apple //c. This is a lovely bit of retro curation.

    If you write up a document of some kind, I’ll read it and give you some feedback. You might want to watch my talk on innovation:

  19. Made a little GUI to allow adjusting the detail bands in my 5k video player. was a good fit -- easy GUI code, and reading / writing the on-disk files is just a single (read) or (write x).

  20. My son’s D&D DM gear — dice, screen, notes, and... bullhorn for talking over a table of noisy teenagers.
