genghisjahn··on Ask HN: What are you reading?
I like a good thick book but I could not finish Monte Cristo. After about the 40th character introduction I just had to put it down. The problem is me, not the book.
genghisjahn··on We're gonna need a lot more mathematicians
But where are the “cure for cancer” papers for it to ingest and then give to us?
genghisjahn··on AI and the Destruction of the Creative Commons
I’m not sure why the lights come on when I flip the switch. I can hand wave and say “electricity” but I suspect there’s more to it.
genghisjahn··on Doomscrolling ourselves to death
My opinion, anything driven by an algorithm is inherently bad. It’s hard giving up those sites, not because that’s where the people are but because we are all addicted to them. If you switch to mastodon or pixelfed, you’ll find good stuff there, but you won’t engage with it as much because it’s not algo driven, which to me is a win.
genghisjahn··on Apple introduces M6 and M5 Ultra
That’s what I have and love it. I have M(N+1) envy but I remind myself that my machine runs great. And it’s paid for.
genghisjahn··on The brain may be about to have its Ozempic moment
My son takes the methylphenidate / guanfacine combo as well and it’s been a game changer.
genghisjahn··on The Lost Treasure of Sid Meier's Pirates
This?

genghisjahn··on Aaron Swartz was prosecuted for scraping, while Meta does it without consequence
That was it.

For the in-crowd the law protects but does not bind. For the out-crowd, the law binds but does not protect.

Can’t remember where I read that but it has stuck with me.

genghisjahn··on A joke domain purchase turned in geopolitical warfare
In my first law class the prof said, "When it doubt, sue everybody."
genghisjahn··on The Amazon Tax
Having small mini-pcs in my basement and a couple of Cloudflare tunnels and Tailscale has been awesome. Made me realize that I've gotten used to paying for software that is free because someone else was hosting. But now I host it and it's a way better experience. I'm not crazy about using Cloudflare, but so far it's been great. Having Postgres, rabbitMQ and Redis all running locally (and then realizing my traffic doesn't need a cache or a queue and just doing it all in Postgres) has been awesome.
genghisjahn··on Strait of Hormuz Live Traffic Tracking
And yes. Reddit had hallucinations too. Often replied with inaccurate statements with utmost confidence and certainty.
genghisjahn··on Dear people who work at the airport
Does in/out mean in the tray or out of the bag?
genghisjahn··on People who grew up with high economic connectedness earn more
Your thesis is that companies pay more (by promoting) to people they could easily backfill instead of just letting them go and replacing them?
genghisjahn··on Humanising LLM Outputs Is Dumb
I am constantly asking Claude to be more terse/brief/ELI5. Improve using the tool. But if I have to scroll to read the output I just can’t follow it.

If I see a long paragraph and I know the author is Neal Stephenson I think “this is going to be dense but good.” LLM long outputs on a code base I know well just make me glassy eyed.

genghisjahn··on I'm switching my phone from Android to Linux
It could be that the HN crowd is getting older? You age, your finger tips dry out, virtual keyboards get wonky.
genghisjahn··on Read the novels and forget everything else
[removed] made the mistake of assuming the contents of the article before reading it. My comment does not apply.
genghisjahn··on Software for One
I totally hear you on that, but for my one off apps (and even some of my not one off apps) if I can't implement a feature in a PWA, I just learn to live without that feature.
genghisjahn··on The AI Aesthetic
That’s what that was. I thought someone there screwed up an image path.
genghisjahn··on LearnVector – Andrew Ng's AI company building one‑to‑one learning experiences
Yeah. That was it. I remembered it wrong (you use chatGPT which I admit, has better voice interaction). I use claude code and type it all. Most of the time for walks/runs I just let my thoughts go whenever. But that's just me. I do really appreciate your post though. I wouldn't have the claude skill without it.
genghisjahn··on LearnVector – Andrew Ng's AI company building one‑to‑one learning experiences
If you are using Claude code, disable recaps.
genghisjahn··on LearnVector – Andrew Ng's AI company building one‑to‑one learning experiences
Somebody here posted about a Socratic method skill for Claude (or whatever your LLM of choice is). I’ve found this to be fantastic. Dropped in a dense PDF about Linear Algebra, Postgres (those are the two I’ve gotten into so far). It’s basically just a skill.md that reads, “Here’s a document, give me an opening statement about the material and ask me a question. As I provide answers, guide me to simpler or more complex areas of the topic. Something something Socratic method.” Works great.
genghisjahn··on Open-weight AI is having its Kubernetes moment
If you can get it implemented for anything you can’t be fired.
genghisjahn··on It's getting harder to focus every day
We had 3pm coffee club at a previous job. It was great. Had our own slack channel(public). As the minutes counted down people would post gifs counting down (/giphy 4, /giphy 3). Most of the dev team would go. We’d go a heavy coffee shop. The talks there and back were great.
genghisjahn··on Verizon is About to Break our Watches
Well, they are providing a valuable service to society. How much money should they be allowed to profit for providing this service?
genghisjahn··on Professor denounces mass AI fraud on an exam at Brown
and there's also the Ivy League grade inflation...

genghisjahn··on Blogging can just be stating the obvious
The first penguin certainly rewards the orcas.
genghisjahn··on The AirPods Effect
Same article was written about the proliferation of the Sony Walkman back in the 80s. Same article was written about newspapers on trains. File under “new thing is bad.”
genghisjahn··on Sixty percent of US consumers say 'AI' in brand messaging is a turnoff
I didn't promote a product. I was showing that low sports radio shows aren't really any better than easy to make AI podcasts that cover the same topics. Just tried and true host personas (the over reactor, the crank seen it all before, the stats guy, the callers) is just wrapped around the stats of the game. People mention claude in their comments all the time and they aren't flagged as promoting a product. The podcast I linked...ah never mind.
genghisjahn··on Sixty percent of US consumers say 'AI' in brand messaging is a turnoff
I mean, not really? I did make it. Thought it would be interesting. Is that I mentioned the name of a company I used?
