yeah the site's clearly vibecoded and isn't opensource, but i also think this is a genuinely interesting design space and more people should be building in it. APL (https://www.dyalog.com/), BQN (https://mlochbaum.github.io/BQN/), J/Jd (https://code.jsoftware.com/wiki/Jd/Overview), Klong (https://news.ycombinator.com/item?id=10586872), Kerf (https://news.ycombinator.com/item?id=9782520), RayforceDB (https://news.ycombinator.com/item?id=45889607), k/q (https://kx.com/) glad there's a new entrant.

First, this is an incredible achievement. I hope that the author(s) can monetize this project. I guess they can try to undercut kx.com's current insanely high subscription costs. Is that a goal? I ask because I cannot find the source code for the project, only downloadable compiled binaries. (No hate on that -- you are free to make lots of money from your hard work and apparent genius!)
Second, in my personal experience, most quants refer to the platform as "kdb+", which uses the languages q (directly), k (indirectly), and qSQL. Is there a reason why the website landing page does not mention kdb+? I assume this is intentional.

Quite cool, but for a new runtime of an existing language it might make sense to compare to, y'know, the other[0] runtimes of that language? Even if one has to omit the best, closed ones for lack of access / permission to benchmark?

Closed source (and vibe-coded) software, especially for a language runtime, is a non-starter for many people including myself. But proprietary license is actually common in the APL and K family of languages. They are fascinating though, and plenty of free/open implemenations exist, for example: https://ktye.github.io/

Not sure why all the hate (sure site may be vibecoded, not all of us are front-end masters and it's at least not spartan)... I've always found k to be fascinating, and cool idea to try and roll a new one. Wish it were wholly open source, but cool to have a new variant that seems to bench well.

q is the programming language underpinning kdb+ by Kx Systems - often claimed (by Kx) to be "the fastest database in the world". Possibly also the most expensive? L is an independent implementation of a q interpreter. To those who reluctantly commercially license kdb+ - this will be a welcome alternative.

Quite the cryptic tytle. Were they trying to save tokens?

benchmarks at https://github.com/l-labs unlike klong/ngn/bqn et al (which are GREAT) this has the goal of full production database compatibility (and full language compatibility).

These languages are very niche, isn't it? Unless you are interested in getting a job with specific companies, I don't see why you would learn them.

So many keyboard warriors with all the hate about a vibe coded website? If you judge a project based on its website, that tells everything about you.

We'd like to see some benchmarks against open and closed k interpreters please! I'm curious how well a vibe coded k/q interpreter stands up to Shakti or whatever Mr. Whitney is letting out the door right now.

If this kind of thing interests you, you can try KlongPy (based on Klong) which also now has backprop support making it a differential array language.

I thought too long to find out what a means in a new runtime.

Memory got faster, no?

if you k you k ;-) for the uninitiated, this looks like some wallstreet quant's new startup. Initially I thought it was the rebrand of shakti, Arthur Whites most recent rewrite of an array language. It's purpose built tooling for computing tick data for financial markets, but the best way I can describe it is codegolf for experienced programmers who don't want to give up the keyboard. these tools combine dataaccess and the ability to compute against that data with as few abstractions as possible.

As someone who does not know what k4, qSQL, or q are, reading through the landing page of this website was giving me mild schizophrenia. And then I tried to search for these things in the old way, and received incredibly dry technical sites that still don’t tell me what it is, and all these names are wildly SEO unfriendly. So I had Claude give me context and it’s apparently the database Wall Street uses for tick data. Sounds cool but, jeez.

Flagged, lots of unexplained grandiose thinking like “k and q made the vector the unit of thought.” K and q are unexplained and unlinked and “unit vector of thought” is pseudoscientific language
Extremely likely to be AI, though I’m not sure that matters for rules re: submissions

Am I the only one not getting the hate for the website? The site looks fine to me. What about it is bad?
