24 hour trading is avail on brokers like IBK, webull, hood, etrade, Schwab (short lists of tickers, but useful ones, QQQ, SPY SMH etc). If you're looking at just ARca's order book, liquidity is pretty thin overnight before 4am EST
So while this may sound like it'll be in the case studies of ERP/CRM etc failed projects, which has some very memorable writeups, the judgement of failure/success is still out (or shd we say jury is out)
i don't actually know a lot about split/ergo/mech's and don't know of any non-rabbit-holey info sites but you can learn a bit about 1 and 2 handed split ergo's and ZMK/QMK firmware mappings at https://old.reddit.com/r/ErgoMechKeyboards/
ZMK's docs are pretty good https://zmk.dev/docs/keymaps
But we are around or just over Bessent's pain points for /ZB and /zn so we'll see

- Vix, IV vs realized/historical

- commodity prompt spreads, contangos
I've been listening to a lot of 21st century string quartets, Ben Johnston (student of Partsch), Caroline Shaw, Garth Knox, Kevin Puts and trying to figure out how they notate them. Also spend time on fretless bass/guitar, pedal/lap steel doing ... stuff.
The somewhat brighter bullet points: Northern California reservoirs are doing prety well, and the Bureau of Reclamatn can again kick the can by draining Flaming Gorge but i think this only works every few years:

i worked in APL2 fulltime years ago, big asset backed bond models, big as in some of the largest workspaces the IBM support people had ever seen. Never occurred to me to pick it up again, but i have been looking for the Polivka/Pakin book i learned out of (the edition prior to their APL2 edition).

- vix futures, front month has only hit 40 3x in 20 years, tho for sustained period starting late 2007 when the contracts were a lot lower volume
- /zb /zn futures contracts, BBB OAS spread on St. Louis fed website,
- credit default swaps, i can't find free public website
- some people say you can get insight from polymarket, other betting sites
- GDP now on Atlanta Fed website, note gold haircut
- other sites monitor options' large buys, skews and dex/gex (gamma exposure) on indexes, futures and single stocks but those sites are $ subscription
One niche, there's lots of people looking for help coding stock/futures trading apps in sierra chart, ninja and multi trader, etc. These are in c++, c#/framework, python, mostly.
On the latter, work your network, seek out busines owners/managers who are in need of IT/web/database/email list type work and have people vouch for your tech cred/integrity (very important)

with the gaming oriented brands you often have to turn down RGB effects to make them tolerable, certain brands have switches that actuate high in the range of motion and it's often not easy to tell if the switches are soldered or have swappable sockets

also the latest/greatest in split ergos seem to be the svalboards, ordered a 1 finger cluster to try but have no info about them yet
It's just a lot easier to ask a live human
When i worked with a few dozen APL2 devs, there was a devoted clique who would always remind us of ways in which Sharp APL was superior to IBM's tho i can't remember details. I only remember STSC and APL2 dialects weren't all that different. And now, when i do C#, linq and kotlin, it seems like a romanization (and update) of APL.
Come to think of it, the 21st century/mutable by default is a nice group also: groovy, C#, golang, TS, Dart and Bright's D.
