I'm reading 'Love in the Time of Cholera' atm and was literally too afraid to look up words for fear of distraction. I can't wait to use flashcards! A favorites section might be a cool feature - for words you want to start working into conversations
I checked it out, have you considered doing something similar to a diary? To keep aspiring musicians on track with practice, theory, performing etc. I play guitar and find it difficult to commit time to practice and improve. Would love a planner/diary that could help me do that.
I want to second that (also a guitarist with almost zero time on hands). There are so many books, and now apps that help practice, but I don’t know any tools that have helped me keep on track.
Has anyone experienced their anxiety symptoms flare up after a strenuous workout? I know this seems fairly obvious, but I was just wondering if anyone else experiences this.
I had a really rough month where my 2yo was jet lagged and waking up crying multiple times a night. After that I've had two months of anxiety on and off, this is really helpful. Have always suspected that sleep could have been the trigger but didn't realize that an hour a night could make such a huge difference. Cheers!
And of course this is a self-reinforcing downward spiral. Sleep quality destroyed by kids, underperformance in all areas of life due to sleep deprivation, anxiety and stress due to underperformance, making it harder to get to sleep...
A conversation based on excerpts of his 2017 essay on AI, that raises important socio-economic and philosophical questions about the future of humanity and AI.
Was really curious as to what Airbus was using, thanks for this! Why not just use the latest CPUs though? I can't imagine the cost would be relatively significant in the greater scheme of things. Are the legacy CPU's really better for this use-case?
Aero industry moves at a very slow pace. The state of the art F-22 Raptor uses intel 386 cpu and the F-35 lightning upgraded to more "modern" PowerPC CPUs, similar to the ones on legacy Macs.
Planes don't need insane multitasking processing power like our smartphones or PCs. They mostly do signal processing and sensor fusion in a tight loop which is quite trivial even for legacy CPUs as it's basic flight math equations which results in highly optimized code.
In terms of aero chips, basic is always better as you want a silicon that's tried and tested for decades to have a deep understanding of it's quirks and bugs so you know the code execution is reliable.
I was trying to investigate this about Airbus but without much luck. I even found they use a 80186 with another Motorola processor for cross checking values. I also wonder does maybe Airbus have "more" processors for different tasks? I also read their A340 uses 80386. That might mean they have expertise and groundwork set to migrate the A320 to the i386, of they already haven't (hard to find data). The 'bus is a much more digitalised plane and 20 years younger, I would guess they've got something different or a bit more modern.
Probably minuscule when stacked next to the costs of grounding all 737MAXs for half a year and the negative publicity of multiple planes catastrophically nosediving out of the sky
>Are the legacy CPU's really better for this use-case?
Yes. Legacy CPU's have the advantage of years and years of testing. Newer CPU's are not as reliable for safety-critical systems inasmuch as not all the kinks have been worked out, and there may be catastrophic bugs in newer designs that won't be discovered until mass deployment on consumer markets.
Meltdown and Spectre have sent shock-waves through the safety-computing industry. I wouldn't want to fly on any plane that is running on the latest-generation Intel chips - they're just not settled yet.
