(IMO)The 2 sigma's are getting receptive audiences as pre-announces of layoffs at Amazon, MS and others yield the analog of a 50 VIX in the options markets, where enumerating mid/good/bad scenarios goes from difficult to impossible.


Lots of good info in OPs article and this thread, and good band/classical tradition suggests, also.

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.


Years ago, i visited a well funded project to generate power from (I think) similar kites, high aspect ratio front rams, I'll have to ask what happened to them.


we have 2 very recent Tesla 3's here (in the US, tho i'm not sure which gen HW 3 or 4 they have and I don't drive them), i'm told (judging by center console) reliably identify anything they need to but FSD isn't happy in construction zones with orange cones and will go slow.


In Germany (and a lot of the world, really) town centers are very old and streets are narrow and are shared. Over here it is also totally legal to cross the road wherever you like.

Also, due to the narrow roads it's standard practice to be in eye contact with other users of the shared space to make sure who drives/walks next.

Car AIs can not hold eye contact, so this is where the problem starts.

And, this one of course is very very specific just to Germany: On parts of the Autobahn you have to always expect another car approaching on the left lane with 250 km/h / 155 MPH, so you really have to use the rear view mirror very early to get an idea at what speed that car may be moving. The reach of the Tesla back camera is far too low for another driver at that speed being able to break so to not crash into your back.

So, when it comes to Germany even if the system worked better, there simply is no place where you could really make use of it without either killing people or getting killed.


as a parallel track, PC build/repair is pretty easy but underappreciated and definitely a marketable skill. This could include building peripherals, keyboards, especially, which i consioder a really valuable skill.


This is a complex set of constraints, and people in Arizona, Nevada and Colorado etc have different perspectives on this. In my mind Lakes Powell/ Mead running low is somehow congruent to the /ZB Treasury futures contract (30 year) running lower, somehow there's a common economic invariant lurking in there.

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:

been awhile sincei looked but i thought Drysdale's Effective Rust was a truly excellent book and aimed at simlar audience

Not bad, curious about price, but as noted by others in thread, the only really special thing are the keycaps, given those you could replicate functionality on any ZMK/QMK keyboard. I might try this as a layer of a glove 80 or ZSA voyager, s.t. like that


here's 2 oft cited papers on PFOF so people can think about this, general conclusions are there is more possibility of actions detrimental to retail traders in options markets

Interesting, how did you choose APL?

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).


I came to APL slowly, originally motivated by some combination of fascination with the syntax and desire to break into the financial sector.

However, what got me to invest in earnest study was hitting today beginner's wall and realizing that I had no idea what Iverson was on about with his design principles.

APL is really different these days, as far as I hear. Dyalog APL is the only vendor actively working on the language these days, and the old hats tell me that things like dfns, trains, and various operators make modern APL quite different from APL even just 15 years ago.
