@willdepue The bottlenecks are usually auth and talking to people when you do this at a big company. You need a the day for that haha

day long hackathons are kinda broken in the agent era. i propose the hour long hackathon, which feels much more appropriate

What do you do if someone on your team is using AI negligently? I.e. not reviewing, not caring, leaning into the slop. This, of course, was a problem pre-AI. But the "code is cheap" mind virus is making it worse IMO.

@sunbains I would love a new B+ tree database. It seems the ingredients aren’t there to make it a successful company though. What do you think?

I haven’t been able to saturate the disks yet. There is room to move, bottlenecked on CPU. I’ve come to the conclusion that database software today is very inefficient. Bit rot, siloed components, half arsed memory management, inefficient IO strategies etc. With all the new tooling available today, there is a chance to rethink past assumptions.

@eatonphil @Shopify @tryprofound Thanks! Stoked

@cameron_p_m @Shopify @tryprofound Big news!! Congrats!!!

Last day at @Shopify today after 7.5 years. From ~100k RPS to ~9 million RPS. Start at @tryprofound on Monday. Also moving to SF, so if anyone is around town would love to chat.

That’s with ~50 Million queries per second. p99 of 2ms isn’t so bad either.

This chart blows my mind. MySQL p50 is now 80us in production at Shopify. Yes that’s microseconds.

@kumard_3 @neondatabase @PlanetScale This is an order of magnitude above normal

Switching from @neondatabase to @PlanetScale to save on costs. wanted to see how they actually stack up first. Same region. Same queries. @neondatabase → ~33ms (avg) @PlanetScale → ~61ms(avg) Not a massive gap, but I honestly thought it'd be the other way around.

I changed from using SwitUI to AppKit for my macOS apps and it feels like I was living in the dark ages. The power is just incredible.

@samlambert semi sync replication?

I just checked in on one of our workloads: 1,375 QPS/core

@TheStalwart @Jesse_Livermore @Havelock_AI Still going on. I can help fix if you want.

@cameron_p_m @Jesse_Livermore @Havelock_AI Try again. Tell me if it’s still happening

Used the @Havelock_AI API to score every speech that Janet Yellen gave either at the Fed or The White House. Look at the distribution between when she was in a political position vs. when she was in a technocratic position.

Jan 2026 is when it will finally get completed.

Tried to write a post on how I use AI in January 2025 and it’s very different than Aug 2025 or Oct 2024, when I also tried to write it. But it’s awesome to see the notes. Priors need to be updated so fast.

@benhylak It’s a performance and storage optimization at the cost of a worse user experience for temp directories. It’s usually not worth the cost. It’s terrible UX. I use something much simpler.

i've been using git for a long time and i still don't get why i should use work trees instead of just copying/pasting the folder

@davidcrawshaw same. I made “tclone” which is that + keeps track of the directories you’ve created. github.com/cameron-p-m/d

Lot of folks using git worktrees for agents. I have to confess I find `cp -a repo repo2` easier to understand and manage.

Something that wasn’t possible before. Starting a new project constantly instead of refactoring before shipping. The copy paste nightmare is solved so now it’s about avoiding context pollution or poison design patterns.

Most use LLMs for answers, but I find using them to generate questions is actually much better. What questions should I answer so that I could answer this harder question? What considerations might be missing from this? Generate flash cards for these topics etc etc.

@gbrl_dick decades.cameronpmorgan.com Wanted to be able to search the actual contents of historical images instead of just the metadata.

if you’re an engineer and new claude or codex has allowed you to complete a software passion project i’d love to see it. even better if it’s niche and personal — an app for your family, something janky, a rom hack or web game etc
