I got the idea of writing an emulator in JavaScript in the pre-Chrome era, circa 2007. I remember searching around trying to find whether somebody had done it before. It seemed not, and somebody on a forum declared “that’s not possible”.

To me, it was obviously possible, and I was determined to prove them wrong.

Anyway, this now exists because of that: https://github.com/bfirsh/jsnes

New comment by bfirsh in "Modern iOS Security Features – A Deep Dive into SPTM, TXM, and Exclaves"

Whenever I read about it, I am surprised at the complexity of iOS security. At the hardware level, kernel level, all the various types of sandboxing.

Is this duct tape over historical architectural decisions that assumed trust? Could we design something with less complexity if we designed it from scratch? Are there any operating systems that are designed this way?

Free usage usually goes in sales and marketing. It's effectively a cost of acquiring a customer. This also means it is considered an operating expense rather than a cost of goods sold and doesn't impact your gross margin.

Compute in R&D will be only training and development. Compute for inference will go under COGS. COGS is not reported here but can probably be, um, inferred by filling in the gaps on the income statement.

(Source: I run an inference company.)

Founder of Replicate here. We should be on par or faster for all the top models. e.g. we have the fastest FLUX[dev]: https://artificialanalysis.ai/text-to-image/model-family/flu...

If something's not as fast let me know and we can fix it. ben@replicate.com

You're right -- this wasn't clear. Added another paragraph to explain what you had to do before.

I can confirm these are dangerous. There are several of these in Berkeley and I got knocked off my bicycle on one of them for exactly the reason you describe.

I am from the UK and it makes me wonder why road design in the US is so bad. Just one minute of thinking about this as a lay person would reveal the problem with the design.

Is there some structural reason in the US that would cause it? Perhaps some lack of standards or approval process? Perhaps iteration speed is slower so they don’t get better? Some other incentives going on?
