Under the microscope: A Bug's Life (PlayStation)

Rings of Saturn • 29 implied HN points • 21 Jan 26
đź•ą Technology Video Games Reverse Engineering Emulation Debugging Software Retro Gaming
  1. The PlayStation A Bug’s Life has a hidden unlock-all-levels cheat that you trigger by doing a precise sequence in the Training level: specific actions with berries, jumps, stomps, seeds, getting to the top, collecting exactly seven grains, spinning, pausing, exiting, and holding R1+L2.
  2. Reverse engineering found the game writes 0x000f to memory address 0x80082284 to unlock all levels, and a function executed during the Training stage performs that write when its conditions are met.
  3. The unlock is driven by specific in-game state checks—training level selected, grain_count at seven, Flik’s spinning animation active, exit-from-pause state, and R1+L2 held—so satisfying all those flags enables full level selection.

đź•ą Technology AI ML LLMs Inference Compute Scaling Systems
  1. For years AI advanced by scaling up pre-training—more data, bigger models, and huge GPU time to bake capabilities into fixed weights.
  2. Test-time compute flips that idea by letting models use extra computation during inference to reason, plan, backtrack, and self-correct—basically "letting the model think."
  3. The big implication is that model performance depends not just on training compute but also on how much compute is allowed at inference, changing tradeoffs for how we build and deploy AI.

Different Small Modular Reactor Designs

Erik Explores • 61 implied HN points • 20 Dec 25
đź•ą Technology Nuclear Energy Energy Economics Manufacturing
  1. Small modular reactors come in three main coolant types—light water, molten salt and gas—and choices about fuel form, coolant and neutron speed drive very different safety and performance trade-offs.
  2. Molten salt and high‑temperature gas designs offer stronger passive safety, much higher operating temperatures, and new uses like thermal storage and hydrogen production that conventional water reactors can’t easily do.
  3. Economically and politically, renewables plus batteries are cheaper and scale faster, so nuclear is likely to remain a niche solution unless mass manufacturing, regulation and financing problems are solved; conservative SMR designs are progressing while many novel startups face delays or failure.
