It's not just the arcade machine implementation. The owners of these companies want to go all the way and move everything to data centers so they can rent compute time, similar to …

Or just use kdb+ and 1bn rows a day is par for the course.

The aj function at its heart is a bin ( https://code.kx.com/q/ref/bin/ ) search between the two tables, on the requested columns, to find the indices of the right table to zip onto…

> just like LLM agents were a new layer on top of LLMs, Claws are now a new layer on top of LLM agents, taking the orchestration, scheduling, context, tool calls and a kind of pers…

In this case the majority of the work was done by another company on your instruction. When you signed up was there anything in the terms that said you get ownership over the outpu…

Wayve have been working on London streets for some time now. This is from a few months ago: https://www.youtube.com/watch?v=KvctCbVEvwQ

Another way to look at it is everything a LLM creates is a 'hallucination', some of these 'hallucinations' are more useful than others. I do agree with the parent post. Calling the…

Most applications backed kdb+ do just this. It comes with its own parser and you can query tables using something like an ast. For example the user might ask for data with the cons…

Given Wes McKinney created Pandas for quantitative analysis, it's possible that Pandas wouldn't exist if AQR were paying for a q license.

The overview here is better than the marketing: https://code.kx.com/q4m3/0_Overview/

That does require someone to know that the take operator continues to treat the y list as circular when x is a list. I think this form might be a bit easier: {(x,x)#(x*x)#1,x#0}

It's not because of the left of right evaluation. If the difference was that simple, most humans, let alone LLMs, wouldn't struggle with picking up q when they come from the common…

I use perforce for my personal projects. Helix P4V's various ways of visualising streams, diffs and revisions are so nice.

These days it's usually better to try and find players on youtube or twitch than to read text based reviews.

Financial market data (especially FX data) can have thousands of ticks per second. It's not unheard of for data engineers in that space to sometimes handle 1TB per day.

We do this in q/kdb+ systems often for patches. An important thing about these languages is that this kind of workflow is part of the core for solving problems. So when you are bui…

Calling them hallucinations was a huge mistake.

In 2021/2022 there were 60 people in the UK who probably fall into that last group. Together their taxes accounted for about 1.4% of the UK tax bill despite being something like 0.…

Shinmera recently talked about porting SBCL to the switch: https://reader.tymoon.eu/article/437

A couple of old fogies down in Tunbridge Wells, "I say old chap, how very uncouth." Meanwhile everyone else, "It's been almost 50 years since Fawlty Towers. Took them long enough."…

Transport Fever 2 if you like choo-choos.

APL (along with Matlab, K, Mathematica, etc.) was one of the influences for NumPy anyway.
