Group Borrowing: Zero-Cost Memory Safety with Fewer Restrictions
Child groups That’s a useful rule, and it can get us pretty far. But let’s make it even more specific, so we can prove more programs memory-safe. For example, look at this snippet: ref hp_ref = d.hp # Ref to contents damage = a.calculate_damage(d) a_energy_cost = a.calculate_attack_cost(d) d_energy_cost = d.calculate_defend_cost(a) a.use_energy(a_energy_cost) d.use_energy(d_energy_cost) d.damage(damage) print(hp_ref) # […]

The Math Behind GANs
Generative Adversarial Networks refer to a family of generative models that seek to discover the underlying distribution behind a certain data generating process. This distribution is discovered through an adversarial competition between a generator and a discriminator. As we saw in an earlier introductory post on GANs, the two models are trained such that the […]

Are OpenAI and Anthropic Losing Money on Inference?
I keep hearing what a cash incinerator AI is, especially around inference. While it seems reasonable on the surface, I’ve often been wary of these kind of claims, so I decided to do some digging. I haven’t seen anyone really try to deconstruct the costs in running inference at scale and the economics really interest […]
