How enforceable is GDPR against foreigners anyways? FANGs are motivated to comply because any sufficiently large corporation will inevitably have assets that the EU can freeze, but otherwise it's just a limp-dick attempt at exerting sovereignty well beyond their borders which will get laughed out of any court.

GDPR isn’t enforceable against foreign companies. It is enforceable against subsidiaries registered within the EU. Living in Germany means you are doing business with Google GmbH (or likely, the Irish subsidiary). Don’t want to comply with German law? Then Google GmbH must exit the German market.

Car sharing in Germany such as Bolt and Miles. The pickup and drop-off anywhere model is so much more convenient than the point-to-point or round trip model that zip car uses. They are cost competitive with public transit or private car ownership.

I’ve been on a reboot too. I squatted through bad mobility for years and got quite strong, but reinforced all of the bad movement patterns. It’s been hard to unlearn that muscle memory.

Opening up and releasing my chest, t-spine and pelvic floor has been a long and slow process (8 months so far) but I’m finally relearning proper movement.

What sort of programming did you use to work ok your mobility? I’ve been looking to do the same.

This probably covers it, not sure if the original papers are mentioned in here but I haven't heard of these guys misleading people: https://www.youtube.com/watch?v=XcvhERcZpWw

bacr · 4 years ago

It does indeed cover it, starting at the 35 minute mark. It’ll require some more digging if you want the primary sources they reference.

bacr commented on Ask HN: How come HN folks are so well-versed in social sciences and humanities? · Posted by u/samh748

swiftcoder · 4 years ago

HN is pretty tech centric, and pretty US tech centric in particular. Those select heavily for folks who attended the American style of liberal arts university.

American liberal arts programs are design to provide a very broad education, so Computer Science majors will still take a bunch of courses in the humanities - or even double-major (my other degree is in Philosophy, and many of my classmates double majored in things like History or Political Science).

bacr · 4 years ago

I’d agree with this assessment. The American liberal arts education can do a fantastic job at producing well rounded and well read students. At the very least exposing people to arts and humanities — or conversely to the sciences.

There has been a lot of work in this space, and it’s a lot of fun to read around and play with. The Magenta team at google developed a differentiable digital signal processing system that is what you are describing. Here it is doing some tone transfer: https://sites.research.google/tonetransfer/about

I thought immediately of LightOns work: https://lighton.ai/photonic-computing-for-ai/

And this is very much already a vetted approach. They use photonics circuits to implement random projections, which can be used to speed up t linear algebra in modern ML workflows. It’s no magic monocle, rather a pretty interesting co-processor racked away in some data center.

dalke · 5 years ago

At a conference presentation the other day a speaker made the claim that well-written Julia code was as fast as well-written C code while as expressive as Python, so it solved the two language problem.

My Python package uses a C extension for performance. That C extension uses AVX2 intrinsics. How well does Julia support intrinsics?

Even supporting something like __builtin_popcountll() would be nice, but http://rosettacode.org/wiki/Population_count#Julia suggests that it's not supported in Julia.

I've no experience with Julia and my attempt at finding this out on my own failed - does anyone here know about Julia's support for intrinsics?

bacr · 5 years ago

My understanding is that the Julia community is quite interested in having SIMD via e.g. AVX “just work”. I recall reading this post on it a while back: https://juliacomputing.com/blog/2017/09/27/auto-vectorizatio...

The reality is that most of a modelling task is preprocessing your data before it can be passed to a probabilistic model and postprocessing to make decisions using it. The code is usually written in R or Python so there is a strong pressure for your library to be in that language as well.

And being rough around the edges is an ok price to pay for not losing an ecosystem.

bacr · 5 years ago

My take is that most modern PPLs have language bindings in JavaScript/Python/R because they are explicitly courting analysts/data-scientists/applied-statisticians, or they are taking advantage of modern technical stacks implementing auto-diff and co-processor routines.

Most pre- and post- processing (with the exception of visualization) should probably be a part of your model!
