jharohiton Show HN: Galaxium, an experimental WebGPU space explorer

Once a user travels to an object, would be cool to let the camera auto revolve the object slowly (in plane). Especially for kids that could be a cool feature especially you are chrome casting it your largest tv at home. So can leave it on for a while as screensaver

jharohiton Ask HN: Hugging Face is out. Who is hosting open models?

Use them as fallback to my Hermes. Honestly pretty amazing team!

jharohiton Science a New Golden Age

I think what the report says is that onus on R&D is shifting to Corporates and Startup labs which are churning more cutting edge engineering and in some cases science faster

jharohiton Science a New Golden Age

The OG is obv hard to beat but the situation has changed and we did need an update to something that reflected reality more closely. We all know that basic science funding through academia is having struggles

jharohiton Ask HN: Books about Genetic Algorithms

i have been pouring on my 10% free time into evolutionary algorithms. thinking about the premise of what a transformer alternative with evolutionary algorithms look like.

Would be keen on talking to anyone who has been researching in this area. X: @jharohit

jharohiton Ask HN: Will hardware ever be cheap again?

jharohiton Sam Altman may control our future – can he be trusted?

what model was used to create the visual at the top of the article?

jharohiton Making Video Games in 2025 (without an engine)

on that theme it reminds my of the Pico-8 community (although technically it is an engine but you dont need to do engine programming even for generating music!!)

compiled a personal webpage to play with mobile controls and a javascript engine to play the pico-8 games and i love the celeste port on that!

jharohiton The percentage of Show HN posts is increasing, but their scores are decreasing

“Also I have no idea why the average score was increased in 2022. A lot of new users?”

Possibly. Post covid many companies laid off people and that could have led to more time and interaction with HN and many more new builders and solopreneurs joining the community

Non Fiction:

- Breakneck: China's Quest to Engineer the Future by Dan Wang (2025)

- How to Live an Extraordinary Life by Anthony Pompliano (2024)

Fiction:

- The Stars My Destination by Alfred Bester (1956)

- Consider Phlebas (Culture Series #1) by Iain M. Banks (1987)

jharohiton Pocketbase – open-source realtime back end in 1 file

love it. been using for personal projects.

some things that still need to be done before v1 launch:

- easy data migration in and out (right now is a pain if its large volume of data from other DB eg firebase or sqlite!)

- API/programmatic setup of tables (right now its only via UI making it hard to setup large complex tables with variable permissions)

- Multi-instance: easiest is to have another pocketbase in "mirror" mode that it updates once a day or whatever with primary (primary > secondary method like in mongo is a great mechanism, with some kind of voting for primary)

jharohiton AI second brain apps, thoughts?

Obsidian for notes in markdown + Claude Code/Gemini Cli pointed to the Obsidian Vault Folder

There is probably already Obsidian Extension for this in Co-Pilot format

jharohiton 2025 PN7 - Scientists find quasi-moon orbiting the Earth for the last 60 years

jharohiton Ask HN: Has anyone built anything useful using AI?

yes!

Use it everyday https://github.com/jharohit/team-timezone-wall

Also built a AI NDA tracker for all our NDAs in the company which is awesome! We will open source soon.

jharohiton Show HN: Team Timezone Wall (100% offline, single file)

ah! like names of people is it? hmm let me see, good point for larger teams. how would you ideally want to see it - just click on tile and it pops up a textbox with all names? dont want to complicate it

jharohiton Show HN: Team Timezone Wall (100% offline, single file)

You mean you just know the city the person is in but not the timezone?

jharohiton Warp.dev Terminal – Overpriced, Buggy, and AI-Sabotaged My Code

Use Ghostty

jharohiton Terminal app can now run full graphical Linux apps in the latest Android Canary

So...can we run SteamOS then on android?

jharohiton Which SaaS have you been able to replace with AI?

this. plus most CRMs have a huge attack vector for info leak.

jharohiton Which SaaS have you been able to replace with AI?

We have been building tons of internal apps with AI - some just cool widgets vs serious vertical apps.

Cool useful widget - A simple multi city clock homepage which is totally offline https://x.com/jharohit/status/1945756661706330574

vs.

A full blown NDA tracker which uses uploaded signed NDAs to process using gemini 2.5flash, metadata stored in Firebase and then a lightweight table to list all (incl when some are expiring in next 6 months) and what are key items to keep an eye out for, key details (name, company, country, counterparty, etc). NextJS deployed app on standard VM on office server (no replit tho). Will open source this shortly.

jharohiton Ask HN: Is Basecamp Good?

Exact same experience on 1 & 2

jharohiton Ask HN: Is Basecamp Good?

Wow! Thanks for the super detailed feedback. Found myself deja-vuing on my previous experience with it. I guess I was also looking at an IC pov rather than a manager/owner piv (which i had).

jharohiton AI image recognition detects bubble-like structures in the universe

I had eyeballed one in a random image from Hubble few years ago! Finally found my answer of what it was

Great use of AI!

jharohiton Gemini 2.5

why not enable Canvas for this model on Gemini.google.com? Arguably the weakest link of Canvas is the terrible code that Gemini 2.0 Flash writes for Canvas to run..

jharohiton Show HN: Global Ground Station Database – 650 Satellite Ground Stations Mapped

how was the data compiled behind the scenes?

jharohiton Show HN: Factorio Learning Environment – Agents Build Factories

this is cool! How could one extend that to a broader set of games? E.g another one where you can run larger simulations on behaviour are procedural games like No Man's Sky
