I don't actually post much tech stuff here, the vibes here are semi-filtered Carl and I'm into a lot of stuff. I signal boost what I think is important, I post mundanities of life, I halfheartedly promote my work, and I post very inconsistently. @reactiflux.com and @tmir.reactiflux.com are tech alts
the insane thing about online age verification is that it is absolutely a necessary function of modern society. We need government-backed forms of online identification, because otherwise the cost of doing business increases by the amount it costs to defend against malicious actors

I have felt that pressure to remain a detractor. Just so I can keep fitting in with my people. But I realized that would actually be disingenuous of me. Instead I have to own this decision and accept the consequences. I've already lost some connections as a result. I'm sure there will be more.

okay it's starting to feel like, with a proper agent feedback loop, the difference between high quality and low quality software is going to be how many users it has and how good those users are at articulating what problems they face

one of my strongest bozo indicators is use of "nowadays", flat out. any statement including "nowadays" is vapid, ahistorical, and probably some form of -ist

This doesn't surprise me at all, I had realized that plenty of "skills" or "mcp servers" are glorified docs query functions. A well structured index of files seems easier for an LLM to work with vercel.com/blog/agents-...
AGENTS.md outperforms skills in our agent evals - Vercel
A compressed 8KB docs index in AGENTS.md achieved 100% on Next.js 16 API evals. Skills maxed at 79%. Here's what we learned and how to set it up.

it's actually really annoying because I started chasing down this thought, combined with my experience trying to operate @reactiflux.com, and did some research into what projects looked like they were trying to address it. oops it's sama again, with some cryptocurrency-biometrics bs world.org

When software developers tout a tool as “flexible” so one can “set it up any way you want”, experience has taught me that it will require a lot of setup effort to make it useful at all … and it will turn out that one cannot in fact set it up the way •I• want

The fact that you can't look at the code in Next.js and understand the execution context it's running in is like deeply antithetical to the model of programming that React is built upon

Self-examination nothing: y'all need to confront the fact that you owe your academic career to the unique expertise of librarians and archivists.
Who do you think organized those LIBRARIES of texts that you're drawing upon?

If you're an academic who is protective or defensive about your own area of expertise (understandable, in this day and age), but are offended when it's suggested that professional archivists & librarians have unique expertise outside your own experience, that's worth some self-examination
