No extra hardware, stock macbooks and an imac. No fancy apps either, RayCast is probably the only one that overrides default system behavior. It used to be better, a few years ago macOS would run stable for months, but even then I had to resort to ‘killall Dock’ for occasional glitches.

hope not : ) I observed these across three computers on different versions of macOS.

A couple of years ago I noticed that my mac starts collecting weird little bugs if I don’t reboot for a really long time. The cursor starts misbehaving (it won’t reliably change over links, or in graphic editors), switching between apps might take a few seconds, and once I had my keyboard input latency increased by ~500-700ms for every keystroke. These issues go away on reboot. I’m trying rebooting once a week or so now.

I didn’t mean collaboration features. I clumsily used 10,000-users as a measure of the app completeness.

Building (or vibecoding) a markdown editor for a single user and their specific use case, for a 100 users, and for 10,000 users takes different amount of time and effort. In the pre-LLM days people with resolve to make 1-user version were likely to polish it for 100-users and somewhat likely to get it to a stable place when it can satisfy thousands of users.

Today on /r/macapps/ there’s a wave of apps that look good at the first glance but get abandoned before they achieve even a 100-users maturity level.

does anyone know how would e-ink compare to oldschool reflective TN LCD displays (those in Casios from the nineties)? I have a Playdate device with this type of screen and it seems pretty cool, I wonder why so few devices today are taking advantage of it.

Great analysis! a couple of comments:

1. the airfare inflation chart is based on the Bureau of Labor Statistics CPI which is calculated differently from the other metrics in the article; it does take into account routes popularity.

2. today’s average Economy ticket is different from the 1990s ticket: meals, seat pitch, seat selection, baggage. service changed to the point that 1990 Standard Economy is more similar to 2025 Premium Economy.

ffitch — Tue, 12 Aug 2025 18:06:13 +0000

I wonder how modern models fair on NovelQA and FLenQA (benchmarks that test ability to understand long context beyond needle in a haystack retrieval). The only such test on a reasoning model that I found was done on o3-mini-high (https://arxiv.org/abs/2504.21318), it suggests that reasoning noticeably improves FLenQA performance, but this test only explored context up to 3,000 tokens.

ffitch — Sun, 20 Jul 2025 15:37:45 +0000

I’m curious what the policy with the highest long-term benefit would be. The country needs external talent, but would skewing H-1B towards high skill be good? The economy seems to need unskilled labor for the jobs Americans are not interested in. Should the government try to curb hi-tech outsourcing instead, to create more jobs in the States, both for the citizens and the skilled immigrant workers? But that would be protectionism, and protectionism rarely play out well economically.

New comment by ffitch in "Why is AI so slow to spread?"

ffitch — Fri, 18 Jul 2025 06:28:50 +0000

From where I stand, AI seems to enjoy lightning fast adoption. Personal computers became a viable technology in the eighties, slowly penetrated workplace in the nineties, and supposedly registered in labor productivity in the early 2000s. The large language models became practical less then three years ago, and already plenty of businesses boast how they will integrate AI and cut their workforce, while everyone else feel behind and obsolete.

The things like window buttons, remote keyfobs or radio units will have higher margin when sold individually, allowing to lower the base model price.

curious that both YAGNI and YAGRI arguments could realistically be made for the same fields. guess it boils down to whether someone’s YAGRI is stronger than their colleague’s YAGNI ( :

somewhat unrelated to the topic, but I really liked this part of one of the sentences: “did not not only did not”. it does make sense in the sentence btw.
