danr4··on The Token Compression Illusion: Why I'm Skeptical of RTK
this is aboslutely entirely written by AI
danr4··on Poland is now among the 20 largest economies
Poland would've probably been my top relocation priority if it weren't for the atrocious air quality
danr4··on Artemis computer running two instances of MS outlook; they can't figure out why
In space no one can hear you blue screen
danr4··on Anthropic takes legal action against OpenCode
this not true. api keys are supported. only "claude code" is being dropped.

that code is just a cli hint to which LLM they recommend using. so they stop recommending anthropic. rightfully so.

danr4··on Cook: A simple CLI for orchestrating Claude Code
that's rlm
danr4··on Ask HN: Why there are no actual studies that show AI is more productive?
because you can just look at the commit log

danr4··on ADHD and Methylphenidate Use in Prepubertal Children and Adult BMI and Height
i did not stop to get taller, it just felt like crap. I think as you get older and more independent it starts messing with your sense of self.

is it better to be on meds? maybe i don't know. all i have is my experience. and looking back i'd much rather my parents told the school "fu im not giving my kid stimulants just challenge him" and to provide the challenge if the school didn't.

if you're top 1% (definitely not hn average), it's very likely you had "problems at school" simply because it was boring. don't know how old you are but with 1% there's really nothing preventing you from learning whatever it is you want to learn and go do something else.

danr4··on ADHD and Methylphenidate Use in Prepubertal Children and Adult BMI and Height
4 is absolutely insane
danr4··on ADHD and Methylphenidate Use in Prepubertal Children and Adult BMI and Height
This is not known enough.

I was prescribed Ritalin when i was 6 years old, and was considered one of the short kid my entire childhood (and suffered the consequences).

I decided to stop taking meds when I was 17, and in a few years became the tallest of my friend group.

I'm older now, and occasionally have periods where I take what I consider "better" meds like Vyvanse, but there ain't no way i'm letting my kids take ANYTHING until they are much much older and can decide for themselves.

danr4··on When hardware goes end-of-life, companies need to open-source the software
it won't happen. thankfully AI + Android makes it easy to reverse engineer protocols. APKs are hilariously informative. I'm working on my own app+server for the Limitless pendant i bought before the meta acquisition. didn't write a single line of code.

It can evolve into anything based on community votes

licensing with BSL when basically every month the AI world is changing is not a smart decision.

EDIT: funnily enough seems like its using a lot of battery?

danr4··on I got an Nvidia GH200 server for €7.5k on Reddit and converted it to a desktop
one of the coolest things i've seen recently. kudos!
danr4··on Show HN: Hephaestus – Autonomous Multi-Agent Orchestration Framework
still not sold on agent orchestration. needs to be super simple and as close to the native agent interface, like Conductor et al. adding another layer of complexity while LLMs are evolving so rapidly is just fighting against the waves.
danr4··on Cluely Thesis on Virality and Hype
i'm a cluely hater but the fundamentals of the article are pretty good. simply, "viral content" is and ad. and ads need eyeballs and conversions.

whether they end up actually building a good product that isn't just cheating will determine if they will be seen as clowns or geniuses.

danr4··on Scammed out of $130K via fake Google call, spoofed Google email and auth sync
the biggest mistake was thinking google actually provides customer support
