prakashrj··on A Road to Lisp: Which Lisp
https://www.youtube.com/watch?v=LXhsutNKhec&feature=youtu.be

Once you get hang of it, it easy. Following is video of my son who learnt Scheme as first programming language.

prakashrj··on Reduce Token Usage
Thanks for the free service. This is awesome.
prakashrj··on I created my first AI-assisted pull request
I am learning more than before. It helps me build things faster. You can still make it robust, efficient, crafty, etc. You have to improve your AI-assisted coding knowledge to achieve all those things.

I get it now. Hopefully the utility of it will eventually bring some value. Maybe Utility and corresponding LOC should help you assess my work. Since I didn't share what I have, I can see people getting alarmed at 250K lines of code.

Would love to migrate from GSD and try, if there is community around it.
prakashrj··on Get Shit Done: A meta-prompting, context engineering and spec-driven dev system
I would love to take up that challenge. With what I have learnt so far, I am raring to get opportunities to make custom solutions.
prakashrj··on Get Shit Done: A meta-prompting, context engineering and spec-driven dev system
I didn't look at code. In addition to code, I have CI and CD built in. I becomes hard add features after a while, if you cannot have built in CI/CD that will catch regression.

It's good advice. I will only open source, if it has utility.

Openclaw was mostly build by AI. It had 400K lines of code.

You can AI to audit and review. You can put constraints that credentials should never hit disk. In my case, AI uses sed to read my env files, so the credentials don't even show up in the chat.

Things have changed quite a bit. I hope you give GSD a try yourself.

prakashrj··on Get Shit Done: A meta-prompting, context engineering and spec-driven dev system
Goal is to build something that will have value. Once it has value, I can hire a team or open source it, if AI ceases to exist in this world.

It's important to build a local dev environment that GSD can iterate on. Once I have done that, I just discuss with GSD and few hours later features land.

I was not a app developer before, but a systems engineer with devops experience. But I learnt a lot about apple development, app store connect and essential became a app developer in a month. I don't think I can learn so quickly with other humans help.

This is how I test my code currently.

  1. Backend unit tests — fast in-memory tests that run the full suite in ~5 seconds on every save.                                                                 
  2. Full end-to-end tests — automated UI tests that spin up a real cloud server, run through the entire user journey (provision → connect → manage → teardown), and
   verify the app behaves correctly on all supported platforms (phone, tablet, desktop).                                                                            
  3. Screenshot regression tests — every E2E run captures named screenshots and diffs them against saved baselines. Any unintended UI change gets caught            
  automatically.

A self-hosted VPN server manager: a TypeScript/Hono backend that runs on your own VPS, paired with a SwiftUI iOS/macOS app. It lets you provision cloud servers across multiple providers (Hetzner, DigitalOcean, Vultr), manage them via a Tailscale-secured connection with TLS pinning, and control an OpenClaw gateway.

I will open source it soon in few weeks, as I have still complete few more features.

With GSD, I was able to write 250K lines of code in less than a month, without prior knowledge of claude.
prakashrj··on The Little Learner: A Straight Line to Deep Learning (2023)
This is how he learned Scheme.

1. Typing 2. Vim through https://vim-adventures.com/ 3. Little Schemer https://a.co/d/0343Ez4v

Don't assume that they would need more things.

prakashrj··on The Little Learner: A Straight Line to Deep Learning (2023)
That's the video of my son to prove that Scheme can be a first programming language.

prakashrj··on Racket v9.0
After learning to type, he learned vim through https://vim-adventures.com/

Just FYI, if you want to help your daughter as she grows up. Typing skills, VIM and Racket. He doesn't know anything else about computers.

prakashrj··on Racket v9.0
Thanks for helping my son learn it.

Racket is only hard if it's not your first language. Kids can also learn it.

prakashrj··on Lambda Calculus in 383 Bytes (2022)
I agree that you have to do the exercises instead of expecting others to explain and walk you through it.

https://www.youtube.com/watch?v=LXhsutNKhec

Just one programming book was able to help my son, who is 12 yrs old, learn lambda calculus and write a meta circular evaluator.

prakashrj··on Why is homeschooling becoming fashionable?
https://www.youtube.com/watch?v=LXhsutNKhec

Following is recent video of my homeschooled son that this community might appreciate. It gives an opportunity to tailor education and challenge kids potential.

prakashrj··on Category Theory in Programming
Is Bézier curves not enough to fit curve to points? Just checking as I am very curious about this problem.
prakashrj··on Gut bacteria may offer a treatment for autism

Example that some of parents are trying to tell the world that Autism is a gut related issue.

prakashrj··on Gut bacteria may offer a treatment for autism
This is what happens and comes out from guts of kids with Autism.

https://plus.google.com/photos/112611364634545455505/albums/...

I am one of the few parents that could recover the kid from Autism. We have been crying wolf that it's a gut related issue, but mainstream is now slowly catching up.

prakashrj··on Autism detectable in brain long before symptoms appear
Why research has to validate everything? These are facts that children are regressing into Autism after MMR at 15 months.

Science still doesn't know how food gets digested and becomes poop. Will you stop eating, because science doesn't know what really happens during digestion?

prakashrj··on Autism detectable in brain long before symptoms appear
For me this research actually validates the link. Because MMR vaccination is given at 15 months. Parents strongly suspect link between MMR and Autism, not all vaccinations as popularly believed.

Following is vaccination schedule.

https://www.cdc.gov/vaccines/schedules/hcp/imz/child-adolesc...

prakashrj··on Autism detectable in brain long before symptoms appear
Check Vaccination schedule. 1st dose of MMR is given between 12 and 15 months.

https://www.cdc.gov/vaccines/schedules/hcp/imz/child-adolesc...

Unless you regress into severe Autism, it's very difficult for parents or even doctors to recognize Autism until they are atleast 2 years.

Also according to the schedule, there is no big dose around 2 years. After 18 months, there are not many doses on schedule until children are again 4 years.

Most parents complain about MMR vaccination that is scheduled at 15 months. My son regressed into Autism after MMR. It is true. I hope the world realizes it before more children get effected.
