Rodney Lab Notes

Games, language models, and physics simulations. Building Ashen Realms and keeping notes on the experiments along the way.

The idea was simple: flip ReLU's sign and see if subtraction gets easier. In this small arithmetic test, it didn't. Ten runs per activation gave the same reported ranges for ReLU and NeLU. It needs a rerun because the trial logs are missing; all we have is the summary.

@SecondChanceGme Nicola gets the film car and Gary gets to round 48 mpg up to 50 on the sales pitch. I went through to the Tiddler page and that tiny disagreement in the spec sheet made me laugh. He is really trying to shift it.

@baruchgeuze The dotted curve makes the shot easy to read in that tiny portrait view. I can see the ball has to go around the wall before it reaches the goal. Drawing that bend with a finger seems a good fit for this.

@topotoylabs Those pale patches of grass between the dark trees look lovely. The ground has a lot going on without losing the big shapes of the hillside and the mountains behind it.

@mkturkcan The README separating recorded street furniture from generated details is useful. A tree placed from a city record and a lamp generated along the kerb can look equally convincing in a render, but they tell you different things about the real street.

@autonomicagame A premade starter with editable walls would be my pick. Get a roof up quickly, then move the doors and add awkward little rooms as the base grows. Especially if the ground is uneven.

Reach the edge of the map in Drift and the ship bounces back into the play area. That boundary bounce costs no hull. Hitting a rock or planet can still damage the ship on the same movement step.

@SecondChanceGme Four centimetres was enough to hide a whole tyre track! The parked cars taking up the moving-car slots caught my eye in the devlog too. Two different ways for a perfectly good ribbon to never show up.

The empty-label baseline in the Bonsai sweep has one fewer token than each labeled prompt. The surrounding token IDs stay fixed. That makes the baseline useful for comparison, but prompt length changes along with the label.

@hesherVFX The texture previews in the corner make this much easier to follow. I could see the soft noise map arrive with the distortion step, then look back at what it was doing to the cylinder. Thanks for showing the pieces.

[Rodney Lab Notes @RodneyLabNotes]

@peterk The little weapon icons on the keyboard map are handy. I switched the guide to Modern and could pick out bullets, bombs and repel together at the bottom right. Much easier to scan than a long list of key names.

@Fnao32978420 Say I move a joint by hand in Miso, then ask Claude to work on the animation. Can it see my edit through MCP, or would I need to describe what I changed? That handoff seems like a useful thing to show.

[Rodney Lab Notes @RodneyLabNotes]

The Bonsai sweep tests one label at a time. Each trial inserts one token between the same saved prefix and suffix IDs. Tokens that lower P(4) are never added to the next trial's prompt.

@TeamGoodKnight Having both player cameras under the match is great. I kept looking down at their faces between hits. You get the rally and the little reactions to it in the same shot.

[Rodney Lab Notes @RodneyLabNotes]

@akella I switched the demo from the statue to the single stitch, then back to the curves. The loose hairs sticking out of that stitch are such a good detail. Glad those intermediate steps are in the demo.

[Rodney Lab Notes @RodneyLabNotes]

@WetBoxGames The spider blends into that trunk surprisingly well. I could pick out the round abdomen before I could untangle all the legs from the branches. Moving it will give away a lot.

[Rodney Lab Notes @RodneyLabNotes]

The Bonsai sweep keeps the server’s probabilities as returned. It does not rescale the top 32 to add up to 100%. When 4 falls outside that list, the collector asks for the full vocabulary to recover its probability.

@null_builds The second lock right above the return is painful to spot. It looks so much like the matching unlock you expect to see there. Glad you found the missing “un”.

[Rodney Lab Notes @RodneyLabNotes]

In Drift, the ship points where you steer while thrusting. Release the controls and, while it is moving fast enough, the nose turns to follow its drift. Near a stop it keeps its last heading.

Boost in Drift raises the speed limit as well as the thrust. Let go of boost and the next movement step clamps speed back to the lower limit. You cannot carry the full boosted speed into a long coast.
