How do you engineer a system to be resilient against large-scale correlated failures?

wow, turns out CDC6600 is not that far from state-of-the-art in RTL logic even now! (ok, everybody moved from bipolar to field-effect transistors, but it's still impressive they built discrete logic computer that was ten times faster than ICs back then)

on long-tail risks:
> You copy/paste the code, it seems to work, and you don't realize it's broken because you don't run either of these programs which made the same mistake. And you don't find out the error until users report it.
> How could you change your development processes to detect this kind of error prior to shipping it?

(also, one of the reasons I think docker in particular is shit, even though virtual machines and containers in general are great)

TLDR: when people can't compare themselves to other people they cooperate and create wealth. when status is codified, they play status games instead.

I haven't dived into underlying math yet, but it certainly looks interesting

Finally, a book that bridges ML with control theory and dynamical systems (and a bit of chaos theory).

Well written, comprehensive overview of the field. Got quite a few insights and filled the gaps.

Also, I was totally surprised to find that dynamical systems research is nowhere near the 4th paradigm (data-intensive scientific discovery). I thought it's my Google-fu is failing me, but it seems there's really no (published) math yet that enables one to robustly identify, describe and simulate anything beyond simple quadratic or periodic processes :(

Now longing for something similar connecting dynamical systems to game theory, catastrophe theory, emergent behaviors, and multi-agent modeling. And something about time-varying systems/processes :)

Nice to see that even in 2019, there's still room for new short, fast, and practical algorithms. Though note that xor filters aren't a replacement for bloom filters, they're more of an optimization of one particular use case.

an optical metamaterial, finally! now they just need to add a gradient to fully transparent plastic on the edges and it would be great #gits #camo

Neural Linguistic Steganography - encode your message with a secret key into innocent-looking text with GPT-2!
