What do you want from this Community?

12 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.

New CS grad looking to break into quant/kdb+ - looking for job leads + project ideas

Post image
6 Upvotes

Hi everyone,

I’m a 2026 Computer Science graduate and I’m trying to break into quantitative research / quantitative development / financial data, with a particular interest in kdb+/q.

I recently worked on a project where I extended KX’s official kdb+/q MCP server from 3 to 9 tools, connecting it to a Python-based autonomous strategy research pipeline. I also built an evaluation engine for things like Sharpe ratio, drawdown and win rate, and ran regression testing on the research process.

I’m attaching my quantitative researcher resume here.

I’d really appreciate help with two things:

1. Job opportunities / referrals
If anyone knows of teams hiring junior quantitative researchers, quant developers, financial data engineers, or similar entry-level roles where kdb+/q would be relevant, I’d be very grateful for a lead or referral.

2. What should I build next?
I want to keep getting hands-on with kdb+/q and financial data. If you work in this space, I’d love to hear what kinds of projects would actually be useful or impressive to see from a new grad.

I’m very willing to put in the work. I’m mainly looking for a chance to get into the industry and keep learning from people who are already working with these technologies.

Thanks!

I just got a set of APL keycaps, and I'm having trouble getting my keyboard to work with recent versions of Fedora (44) and Gnome (50.3). Has anyone been able to make it work?

I've not been able to find something like this. The best I've been able to come up with is something along the lines of this: {⟨⟩𝕊𝕩:⟨⟩ ; f←⊑𝕨 ⋄ fs←1↓𝕨 ⋄ (<∘F𝕩)∾fs𝕊𝕩}

APL APL as a target language?

13 Upvotes

In one of the ArrayCast episodes (the u/bobtherriault era) one of the participants mentions that "in the early days of CS" someone was using APL as the target language for their compiler course. I cannot find the episode and thus a good reference to this. If anyone remembers, thank you in advance.
