Second this ... have been writing some solutions in Kap, an APL like variant. It's stunning to see 20+ idiomatic solutions in one screen as many problems can be solved in a compact manner. The elegance really reminds one of why we fell in love with Programming in the first place

Nice article. Instructive to see the latest trends and direction for high performance interpreters. Thanks for sharing.

Yes - Concatenation Languages and stack-based languages refer to the same paradigm and group of languages. Forth is the original and oldest. I've looked at Factor and it's a really impressive piece of work. Well worth studying.

New comment by rajandatta in "UK Post Office: 700 Horizon software scandal victims to receive £600k each"

rajandatta — Tue, 19 Sep 2023 00:04:31 +0000

I've followed this matter a little bit as I work in the I.T. industry. I don't live in the UK and have no knowledge of the actors. The government response, including this announcement is shockingly deficient and on the low side of the impact. For a start - it only targets those who were convicted. It does not take into account all actors adversely impacted including falsely accused but not convicted. It doesn't take into account the circumstances of the victims. The government does not at all seem inclined to take any substantive action on this matter other than writing a cheque.

Open question to those in the UK closer to this - How do you see the government's response? What is the public sentiment on the matter. Does anyone have any insight why charges are not being pursued against Post Office Management in light of substantial evidence of wrong doing?

New comment by rajandatta in "Should I Haskell or OCaml?"

rajandatta — Sat, 16 Sep 2023 21:16:01 +0000

I would suggest neither in your position. I suggest trying a language like F#. F# started as with the idea of developing a language with OCaml like syntax and semantics for the .NET platform. Since then its evolved to being a mature, elegant and robust language. It can run on Windows and Linux.

Advantages over OCaml is I suspect a much larger footprint and the ability to tap into all of .NET (huge ecosystem). Plus your skills will be more portable than Haskell or OCaml.

Both Haskell and OCaml are exceptional languages but the ecosystem and market footprint is not great for either. Jane Street has done a lot to evangelize OCaml but it hasn't really moved the needle. Haskell is probably the most different being a lazy functional language. Definitely learn it but using it in real life will be harder.

Fortran, Matlab and all array based languages (APL, J, K, Niall, etc) have these constructs at their core. Ndarray may be a great implementation but the ideas have all been there. I've been exploring J recently and the flexibility and compactness is tremendous.

Personally - I'm waiting for the research on the research on the psychology of expertise in whether forecasting.

Don't know about popularity but Scheme has a SRFI and syntax 'model called Wisp which does away with most brackets. It relies on indentation.

rajandatta — Sat, 29 Jul 2023 16:58:36 +0000

Fascinating article. Looks encouraging. The size of the turbine and the capacity claimed is staggering. Is anyone aware of any materials that explainn how one distributes turbines over a farm to maximize yield? Can a tribune of this scale alter localized flow to require specific distribution patterns?

That sort of reasonableness could be considered Blasphemy on the net.

New comment by rajandatta in "A CERN for Open Source Large-Scale AI"

rajandatta — Sun, 09 Apr 2023 16:59:21 +0000

This petition is an excellent idea. We as humanity need to get closer to the edge if not ahead of AI Development to strive to ensure that a) the wealth and benefits can be generated for societies b) closed and unaccountable parties are not the sole custodians of such a powerful force.

The idea of CERN has a lot of merit because of CERN's success as a multi-national institution. The model will need to be evolved for AI but that's why we need to start now.

This is the start of a new phenomenon for our societies; not the end. It's better for its impact to be managed by society as a whole.

Points 2, 3, 4, 6 .. 13 seem like an excellent set of principles and fundamentals for a society or country even today. Verg well said. Also helps that the author contrasts them with England. Most countries would not meet these standards even today.

Anyone know if there's a Scheme equivalent to lisp-stat. It looks really good. But I'm much more familiar with Scheme than Lisp.

Wouldn't it be 694 million metric tonnes? I million megatons is a hell of a lot.

Thanks for your efforts! Both SQLite and Fossil are brilliant products. Fossil may not meet everyone's needs but its a great tool to be aware of as an option.

Do you know if there frameworks for other languages (Python, JS, TypeScript) that are similar in paradigm to Elm's MVC oriented model? If so - any thoughts?

Thinking of doing the same for a similar scale! Thanks for sharing.

New comment by rajandatta in "Ask HN: Why is this Racket code so fast?"

rajandatta — Sun, 03 Apr 2022 21:02:13 +0000

I don't believe Racket uses Memoization automatically. You can certainly use it easily enough but that's a user decision.
