rytison 45°C cooling design cuts data center water use to near zero

But maybe we want northern winters to stay... northern winters?

rytison Redis 8.8: New array data structure, rate limiter, performance improvements

It kind of is a database:

A key-value database, or key-value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, a data structure more commonly known today as a dictionary.

rytison Bitwarden scrubs 'Always free' and 'Inclusion' values from its site

maybe because the company promised "always free"?

if the company can't keep the promises, then maybe they shouldn't make them in the first place?

rytison HashiCorp co-founder says GitHub 'no longer a place for serious work'

I wonder if there's a place for something like matrix, but for repositories (or maybe matrix protocol can handle that?). A world where we have selfhosted, saas, etc, but all interlinked and searchable? Say I find a project on gitlab, I want to contribute to, I checkout to my personal server (or someone elses hosted), and raise a pr back to original repo. I know it doesn't answer your question, just thinking aloud really.

rytison A sufficiently detailed spec is code

> if the agent has difficulty generating Haskell code then that suggests agents aren't capable of reliably generalizing beyond their training data.

doesn't that apply to flesh-and-bone developers? ask someone who's only working in python to implement their current project in haskell and I'm not so sure you'll get very satisfying results.

rytison Meta’s AI smart glasses and data privacy concerns

> there is a fairly logical combination of settings

I think it's anything but logical, if users (like yourself) have no idea what those settings are, as evident from your previous post.

rytison Apple to soon take up to 30% cut from all Patreon creators in iOS app

> What the use for the app anyway?

Works offline?

rytison Design Thinking Books (2024)

May be it's just me, but the very first example (contacts form) looks better (easier to read) on the left than text in empty space on the right (which is supposed to be the good design)...

rytison Dark Mode vs. Light Mode: Which Is Better?

But not all of us are working in the open air office... Brightly lit office after 5pm in winter (ie after sunset) doesn't mean dark mode is the best option.

rytison PHP 8.5

And what exactly 9-5 has to do with caring for coding or time investment in language learning?

rytison Ask HN: What are you working on? (September 2025)

if the customer owes $0.001, how are you charging that?

rytison Show HN: I made a 3D printed VTOL drone

For anyone not familiar with acronyms (like me), VTOL stands for "Vertical Take-Off and Landing".

rytison Raspberry Pi Lidar Scanner

Extending this line of thought I wonder why tesla didn't make cars on two legs and insisted on using wheels?

(Just wanted to make sure - this is not a stab at you, I'm well aware that the original argument is from tesla)

rytison Mox – modern, secure, all-in-one email server

> Nothing will compare to the Gmail experience

I think this might be a matter of personal preferences. Personally I find GMail very confusing, and not that user friendly.

FastMail UI is so much more intuitive. For me.

> Sound output? Sure, just set up DMA and IRQ yourself for your Soundblaster card. I mean, you have one of those right?

What has OS got to do with possession of some hardware?

rytison Laid off for the first time in my career, and twice in one year

> My biggest piece of advice is don’t be a “ticket taker”. Volunteer to lead larger initiatives.

Sure. But who’s going to do all those boring tickets? I know people need to work for themselves, but this just feels so wrong.

rytison OpenAI O3 breakthrough high score on ARC-AGI-PUB

I agree. I don’t know where this obsession comes from. Obsession with resembling as close to humans as possible. We’re so far from being perfect. If you need proof just look at your teeth. Yes, we’re relatively universal, but a screwdriver is more efficient at driving in screws that our fingers. So please, stop wasting time building perfect universal robots, build more purpose-build ones.

rytison A comparison to Waymo’s auto liability insurance claims at 25M miles

Or even as a pedestrian. I'm sure AI will be fine to slow down if it sees a massive puddle and avoid soaking everyone in 3m radius just for lolz.

rytison Police illegally sell restricted weapons, supplying crime

IMO the reality is:

"the police are total idiots with no [...] knowledge of the law [...]" AND "are willingly corrupt and will brazenly break the law to line their own pockets"

rytison Logica – Declarative logic programming language for data

I suppose something like this: https://stackoverflow.com/a/8270393 ?

rytison How I ship projects at big tech companies

> As far as I could tell, it’s because the CEO or CTO didn’t think the type of work they were doing was worth doing, and also didn’t think they were making a difference.

So the CEO/CTO weren't able to express their concerns and priorities and instead just fired the whole team?

If, as you say, there were no financial reasons, then the team could've been re-purposed to do more meaningful (at least in CEO/CTO eyes) work.

rytison Large language models reduce public knowledge sharing on online Q&A platforms

I think it depends on how the question is constructed: - I want to do X, how do I do it? - I was thinking of doing X to achieve Y, wonder if that's a good idea?

Sometimes, I really want to do X, I know it may be questionable, I know the safest is "probably don't want to do it", and yet, that's not someone else's (or LLMs) business, I know exactly what I want to do, and I'm asking if anyone knows HOW, not IF.

So IMO it's not a flaw, it's a very useful feature, and I really do hope LLMs stay that way.

rytison I bought an encyclopedia

https://pressbooks.nvcc.edu/eng255/chapter/the-mother-of-men...

> At first they lived near a cemetery, and Mencius amused himself with acting the various scenes which he witnessed at the tombs. “This,” said the lady, “is no place for my son;”—and she removed to a house in the market-place. But the change was no improvement. The boy took to playing the part of a salesman, vaunting his wares, and chaffering with customers. His mother sought a new house, and found one at last close by a public school. There her child’s attention was taken with the various exercises of politeness which the scholars were taught, and he endeavoured to imitate them. The mother was satisfied. “This,” she said, “is the proper place for my son.”

rytison IFTTT is killing its pay-what-you-want Legacy Pro plan (2023)

Same, and it’s not only about the price either. I value stability and certainty that things I use and rely upon aren’t going to be shut down.

rytison A ghostly radio station that no one claims to run (2020)

> The Carrington Event was the most intense geomagnetic storm in recorded history, peaking from 1 to 2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in multiple telegraph stations.

rytison Ask HN: What would be the single piece of advice you'd give a non-programmer?

I always thought of it as a datastore. What else is it? A document with one or many tables, each containing rows of highly unstructured records (that can cross reference each other), but essentially it is a data store. Or is this view completely wrong?

rytison Posthog is closing their Slack community in favor of forum

> modern forum stack

Genuinely curious, what would that be?

From user perspective is there anything else to the forum than Read/Post/Search?

Or are you referring to administration and moderation tasks?
