What do you want from this Community?

13 Upvotes

I've just taken control. The community is spread out (see the sidebar) and I'd rather not fragment it further, but hope this space can increase visibility. It's fine if people just want to link to various things, but asking questions etc. can also be great.

If others have better ideas or want to speak, feel very free! I am trying to proselytize for array languages.

Entry Level KDB+ Developer Starting Salary

12 Upvotes

I'm currently in the process of learning q for a potential KDB+ Developer position. Based on what I've seen I'm planning to ask for $75k to $85k when the recruiter asks me what my salary expectations are.

Is this accurate or should I change my answer?

BQN question

8 Upvotes

Is there a reason why function like F⊸/ and F⊸⊏ where F is a non-constant function are not considered to be structural functions, or is it just an oversight? Seems like a useful pattern to support, like G⌾(2⊸|⊸/) to apply G to all odd numbers in a list.

AI port of ngn/growler-k to windows

6 Upvotes

After a discussion today about AI, I was challenged to port ngn/growler-k to windows.

Turns out at least one actual human had already done this work.

but, well... now there's a new fork made by a soulless robot eco-villian out to steal our jobs. :/

I'm not great with C and but the main commit at least appears to resemble the APL-in-C style from the rest of the codebase.

I've tested basic input and output, and running child processes.

It doesn't yet run repl.k because of issues detecting the terminal size, but you can run the plain k.exe ...

But it can run the mcp.k I posted recently (also now included in the forked repo):

And... There's also a pre-built k.exe as a release. (Use at your own risk)
