I hope the test data is the same when comparing the different runs. So the big o notation should be the same across different runs.

This seems to be a very generic/common response to any ai critique. It kind of reinforces my point there’s a lot of situations where the appropriate harness isn’t some agent that’s set to ultra high thinking mode. Chat mode gives the better response and answers the question more quickly

I find that thinking/agent mode sometimes makes it worse/comes up with the same thing and just takes a long time. But I’m sure it’ll be different with fable for a few months until that hype blows over

I guess I’m coming at it from an optimizing market data provider perspective once you preallocate memory the next thing to optimize is the string decimal conversion if the feed isnt binary encoded

That’s quite a bit slower to process. At least if you’re converting to integers to do the calculations and the calculations would be quite a bit slower if you kept the big decimal type

There’s quite a few historical cases of mergers acquisitions being poorly valued aol time warner for example. So maybe v the calculus is different from the execs perspective but it’s not necessarily any better.

I wouldn’t call comparing yourself to Fabrice Ballard and not just saying he’s a better programmer modest.

I don’t know like chess engines didn’t kill chess. You could just play with people that don’t use the “engine”

Not if it drives up energy prices and makes other businesses that employ more people less competitive. Not saying that is the case but it’s certainly not a given

Some of the utilization comparisons are interesting, but the article says 2 trillion was spent on laying fiber but that seems suspicious.

The whole point is that the outages happened not that the ai code caused them. If ai is so useful/amazing then these outages should be less common not more. It’s obviously not rock solid evidence. Yeah ai could be useful and speed up or even improve a code base but there isn’t any evidence that that’s actually improving anything the only real studies point to imagined productivity improvements

If there is really amazing stuff happening with this technology how did we have two recent major outages that were cause by embarrassing problems? I would guess that at least in the cloud flare instance some of the responsible code was ai generated

I think he could have been instrumental to the iphone (not saying he was or wasn't) and whatever he tries next is a complete flop. The ability to be successful is contextual, and great artists can produce mediocre art.

Is there a public generic measure of IT outages with historical data. Severe outages seem to be more common lately, but I don't have any data to back it up.

Interesting that there's only the m5 on the macbook pro. I thought the m4 and m4 pro/max were at the same time on the macbook pro

Thanks for the write up. Seems like a cool pattern I hadn’t heard of before

that is an interesting use case, I hadn't thought about a setup like this with a local redis cache before. Is it the typical advantages of using a db over a filesystem the reason to use redis instead of just reading from memory mapped files?
