rochansinha··on The 1.5°C goal of the Paris Agreement is no longer viable
This feels like I could have written it! I am the same age and run my own clean energy hardware startup. It’s been tough and tiring and I have the same thoughts of just pivoting to an “AI Climate tech solution “ and get some of that money but that seems cynical at best and a scam like most of these carbon credits startups at worst. In any case, I have never considered doing something else for a second. Like you said, someone has to make the choice to work on the harder but more important problems, no matter what.

rochansinha··on Good people refuse to do bad things
It’s an excellent article marred by the last line/ heading.

People do things.

Good or bad is relative to their own biases/experiences/ beliefs and moral compass.

Very few people are truly sociopaths who do evil stuff for personal gain.

Most do it because of the curse of the “banality of evil” (re: <https://en.wikipedia.org/wiki/Eichmann_in_Jerusalem?wprov=sf...>)

Doesn’t make it right, but like everything else in life the reality is much more complex than saying “good people refuse to do bad things”

rochansinha··on "Please Remove All Mannered Prose" and Other LLM Incantations
went through the whole phase of asd-ste100 -> caveman -> wait-what -> “remove mannered prose” And a few others.. Now I just use a vale lint script I made using what worked from the skills and lint the output (docs and scripts) and just ask it to write in plain technical English for its chat messages with full context. Skills just make the entire process bloated beyond belief (apart from the needless context rot and token usage)

Seems it doesn't matter if you opt out or in.. your data will be used for training

rochansinha··on Navier-Stokes – Tristan Buckmaster [pdf]
My response was not targeted towards Open-AI but towards all closed-source AI companies where your data is used for training and/or is visible to the internal agents whether you want it to or not.
rochansinha··on Navier-Stokes – Tristan Buckmaster [pdf]
People here do not seem to be considering the second-order effects of these series of events. No academic institution or enterprise will trust OpenAI, Anthropic or any other non-local AI model with their core IP. There will be severe restrictions on what employees at these companies/institutions can share with AI services even from their personal accounts. (Or I am just overthinking it)

rochansinha··on Ask HN: How many AI agents do you actively use?
I run multiple fable/opus and sol sessions for both chat and coding- I read a lot of academic papers and it grew to a point where I needed to use a reference management system like zotero to keep track of it. So I recently one-shotted a ~1000 pdf literature review folder into a .bibtex file to import into zotero. . Includes multi-step DOI extraction and multi-review steps to reduce false positives. Also can check patents via EPO API. And can interact programmatically with zotero via its API to add tags, notes etc. Very specific to my requirements and codex sol max did it in a single 8-hr goal session with very few bugs

rochansinha··on Ask HN: Favourite science history book of the 20th century?
The Maniac, by Benjamin Labatut. It’s a fictionalised biography of John von Nuemann and the birth of artificial intelligence. Amazing , surreal and unique
rochansinha··on Ask HN: What are your favorite blogs not about AI?
https://ciechanow.ski/ - The coolest blog on how things work but hasn’t seen any activity in a while.
rochansinha··on Ask HN: What was your "oh shit" moment with GenAI?
Built a physics-based dynamic digital twin for an electrolyzer system with full equivalency in thermodynamics, fluid dynamics and electrochemical reactions. A similar level of complexity is usually available in software like Aspen or Siemens which are a quarter million dollars license/yr. Insane.
