@wongmjane And… was it a good result? Or was it artificial/choppy? I had a similar experience with a local hospital a few months back, but I wonder if there was a human at all on the other side or not… diction/accent/energy was too perfect to be true (it was 2 am on a Sunday)

New on our Engineering blog: Creating in-house source control.

In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.

Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: https://t.co/wzNkwHs7IN

There are a few things that I look back on as my mistakes in the early days.

Quake was overly ambitious technically. We could have done all the great multiplayer and modding work inside a Doom++ engine, allowing the designers to work with a more stable base instead of rug-pulling everything out from underneath them a couple times. The follow up game could have then brought in full 6DOF environments and characters.

I pushed everyone too hard. I didn’t appreciate how maturing companies need more slack, and that running people at startup intensity constantly will wear them out. Quake was also where I really had to accept my personal limits. I was working pretty much as hard as humanly possible, and I was still slipping past my goal points.

On all of the founders’ shoulders, our original corporate stock arrangement and buy/sell agreement was a mistake, and resulted in bad incentives. We wanted to ensure that all ownership rested in the hands of people working hard on current projects, but the Silicon Valley standard approach of vesting stock would have worked out better.

One real problem that I don’t accept the blame for is that we were insisting that level designers be not just game designers, but also have strong visual design esthetics. They needed to make things that not only played well, but looked awesome, and it got more challenging as the technology provided a richer palette. Romero covered that well, which set our company expectations early on.

We should have figured out how to pair up artists and designers earlier, but there was infighting among the designers, and the ones that could manage the visuals were happy to disparage the ones that couldn’t.

Sorry, Sandy.

I haven't had this much fun programming in a long time. But it is not sustainable. Agentic coding is mentally expensive.

Software development was always about making decisions. Today, agents compress the timeline.

My favorite thing bout Claude thus far is I have apparently put off learning React long enough that it doesn't matter.
