kirubakaran··on Six Math Essentials
The above page has the ToC:

1. numbers as the gateway to quantitative thinking

2. algebra as the gateway to abstraction

3. geometry as a way to calculate beyond what we can see

4. probability as a tool to navigate uncertainty with rigorous thinking

5. analysis as a means to tame the very large or the very small

6. dynamics as the mathematics of change

kirubakaran··on Starfall – Affordable, routine access to microgravity
Sufficiently advanced arrogance is indistinguishable from stupidity
kirubakaran··on Digital minimalism
I agree with that. Thanks for your patience, and for taking my comment the right way.
kirubakaran··on Digital minimalism
The "cure" is worse than the disease. But sure, 95% crypto projects give the 5% a bad name, and that's not fair.

kirubakaran··on The St. Helena 5 pence coin shows Jonathan, a roughly 190 year old tortoise
The story goes that while the Americans spent billions putting thrusters on their tortoises, the Russians simply duct-taped ordinary pencils on the their tortoises, making them unflippable.

Warning: Auto-playing video! (Thought I had that turned off in Firefox, but looks like I had done that just on Youtube. At full volume, it gave me quite a jolt)
kirubakaran··on Tell HN: I've been paying for a rural Tanzanian's education for 10 years
Just a heads up (in case you're able to let the founder know) that the "Fundraise" and "Pledge" buttons on that page lead to 'page not found' error. "Give monthly" button works though.

kirubakaran··on Car is a smartphone on wheels. Here's who's listening
I agree that extremists of all stripes are troublesome for various reasons. The sibling comment by `odo1242` already answers the y-axis question. I want to note that these are idealizations, and may not perfectly map to the parties labeling themselves as such.
kirubakaran··on Car is a smartphone on wheels. Here's who's listening
In the political alignment chart, authoritarianism falls on y axis, whereas left/right is x axis. This explains why you find people from both sides supporting it. They're essentially the same side as far as this topic is concerned.

kirubakaran··on Bill to Ban Private Equity from Owning Medical Practices
My life goal that I can't work on yet is to run vet clinics as a non-profit in locations where private equity has a monopoly and are in extraction mode. With operational excellence, I think they can be out-competed by running a cost effective practice, so people don't have to decide between putting their pet down prematurely, and spending $5k per night (yes, that happened to my friend in San Francisco. $5k/night is not an exaggeration).

The predatory businesses are able to do the extraction only because of the practical monopoly they have in a neighborhood.

I believe the ops can be open sourced and replicated franchise style. And vets, who originally get into the career because they love animals will be drawn to it, and they have bills to pay, but that can be taken care of with a reasonable payment structure.

I hope someone else does this so I don't have to. But I think I have to at some point. I'd also love to hear if this is a dumb idea.

kirubakaran··on NYC may require landlords and realtors to disclose the use of AI in listings
Do mention your app! HN only frowns upon astroturfing. If you disclose that it is your app, then it's fine to link to it.
kirubakaran··on Ask HN: How do you manage too many open tabs?
I save them to https://histre.com/ [1] using the browser extension. This can save all tabs in a browser window into a collection, or even multiple windows each into their own collection. This also makes everything searchable.

What a weird way for them to say "we don't know"! It's like saying this house has 0 to 100 bathrooms.

kirubakaran··on Ask HN: What Are You Working On? (July 2026)
I needed to get customers for Hyperclast [1], but I kept procrastinating on the go-to-market tasks. I'd rather be building, you know! So I created https://tractionbeast.com/ as a tool for myself. It gives me bite-sized tasks every day. I just review and do them. This completely removes the inertia for me. My other founder-friends like it too so I turned it into a product.

If you're an early stage b2b founder, I'd love to hear your feedback about TractionBeast.

kirubakaran··on GPT-5.6 Sol Ultra will be in Codex
This is why I don't think Fable will be taken away. Not for long anyway.
