If you ask ChatGPT to reply in the style of Arthur Whitney, you get amazingly concise summaries. Like a language verion of this code. I use that prompt often.

#112The website reads like an edgy script-kiddy blog. Is K actually a useful project, or is it just a passion project of someone who happens to be sort of famous?
> The website reads like an edgy script-kiddy blog. The code does, as well. Either Mr. Whitney's brain is not wired like a regular homo sapiens sapiens, or the entire thing smells of "I am smarted than you and I don't need to lower myself to your level." I do not buy for a single second that for Mr. Whitney debugging IOCCC-level obfuscated code is easier than plain C code. One writes "normal code" because one will ha…
What if he is smarter than you and doesn’t need to lower himself to your level.

#113OMG, just yesterday I wrote a comment saying that I regret not learning K (I instead chose J) due to being too hung up on the notion of free software at the time... What a coincidence! Now I have no excuses anymore, time to learn K!
How those two compare?
K specializes in financial data, i.e. lists of 1d arrays. Other APLs, and J, are more high-dimensional math oriented and specialize in true multidimensional arrays.

#114Everyone here charges too little for software. the free(MIT license) version is shakti.com/k/k.zip the supported version(supported and 10 to 100 times faster) is $100K per month(minimum) https://groups.google.com/g/shaktidb/c/5SPufca3mo4
They’ve been charging a that amount forever, it’s a crazy ask. But you’ll be happy to hear that the quoted price is about 80% off of the price in 2000, so take advantage of the discount. In 2000 it was $100K/month.

#115And I though that Skala, FP (monad in X is just a monoid in the category of endofunctors of X) people are pretentious sect, this is so much worse, given their customer base, I immediately presume that this is nothing more than approach to deliberately make things unintelligible for as many people as possible, so that your white collar hedge fund guy would have heart stroke just by glancing at this source code, not ev…
Try it or any other APL for 3 months. You will change your mind.

> a sign that a programmer hasn't worked on anything substantial Maybe you want to check who he is?
I meant I don't know as in I haven't actually worked with him. Based on what I've seen before as well as the supplied code, I would be very skeptical to have him on my team.
He would be your entire team

Oh, it's just racking millions of dollars from big bank users every year. Nothing a script-kiddy couldn't achieve...

Even worse, as then the bus factor is as bad as it can get.

#119He might be a smart person, with a very high IQ and on a different level than the rest of us, but by writing with this style, with no comments, with no proper capitalization/style and with this attitude, he’s putting me off (IMHO). Oftentimes, the way something is presented and how the language is used, might be as important as the thing itself ;-)
I’ve always told myself- no matter how smart my idea is , if no one else understands it it could be as if it didn’t exist.

Quick for building a website? Probably not. Quick for evaluating some idea you just had if you are a quant? Yes absolutely! So imagine you have a massive dataset, and an idea. For testing out your idea you want that data to be in an “online analytical processing” (OLAP) kind of database. These typically store the data by column not row and other tricks to speed up crunching through reads, trading off write performanc…
I would probably use Matlab for that sort of stuff tbh. Is K faster than Matlab?
For using a heap of libs to compute something that has been done a thousand times? No. For writing a completely new data processing pipeline from scratch? Much, much faster! Array langs have decent performance, but that's not why they are used. They are used because you develop faster for the kind of problem they're good at. People always conflate those two aspects. I use J for scientific research.
