CositaS··on Unexpected 'Black Swan' defect discovered in soft matter for first time
The actual article this story is about: https://www.pnas.org/content/118/12/e2018977118

(the link was there but buried at the bottom of the page)

CositaS··on Beeple Mania
I always see people point to 'just round the corner' future Proof of Stake systems when the energy waste topic comes up, but it seems like there are still a lot of big unsolved challenges with that, as well as new problems introduced by it.

As long as there's no actual widespread fully working currency using only PoS, it's a bit like justifying the emissions from flying by pointing to experimental solar powered aircraft, and saying all flights will be solar powered any day now.

CositaS··on Bitcoin and Pollution – The Definitive Answer
I keep seeing discussions of this include something like 'but it will all be moving to proof of stake soon', which seems to me a bit like arguing for how green air travel is by saying we'll have solar powered airplanes soon. A lot of faith seems to be being placed in an unproven advance, which if it is really possible at all (and that's a much bigger if than many acknowledge), would introduce all sorts of new problems.
CositaS··on Raspberry Pi 400 Desktop PC
A flatscreen? as opposed to a CRT?
CositaS··on Pulse oximeters give biased results for people with darker skin
Also, while they might not change plan because of a reading of 93 instead of 95 - the article describes a bias of up to 8%, which does seem enough to be significant.
CositaS··on Autodesk criticised by architects
https://www.visualarq.com/ adds BIM tools to Rhino (and the total price of perpetual licenses for Rhino+VisualARQ is still significantly less than a year's Revit subscription)
CositaS··on Show HN: GIF Directions
At first I was assuming this was using streetview. I realise not everywhere is included on streetview, but when it is, it would be nice to have the option of using that instead of having to shoot your own video.
CositaS··on John Peel Sessions
There's more to the story than that: https://www.independent.co.uk/voices/john-peel-allegations-m...
CositaS··on H3: Uber’s Hexagonal Hierarchical Spatial Index (2018)
I think it's clear what they meant was not actually 'the most complex shape' but the regular polygon with the most sides that can tessellate.
CositaS··on Nvidia Extends PhysX for High Fidelity Simulations, Goes Open Source
Can anyone who has used both give an impression of how PhysX compares to Bullet?
CositaS··on Holographic Displays at the TGS2018
I wonder why the Voxon display uses a vertically oscillating membrane instead of a spinning one. I would have guessed that spinning would be the easier option.
CositaS··on Preventing Muscle Loss as We Age
Prostrate cancer? don't take it lying down.
CositaS··on Are gender quotas good for business?
One problem with this reasoning is that it assumes one can assign a fitness function to each single employee in isolation, independent of their different roles and how they relate to each other.
CositaS··on Apple Monitoring Blood Glucose
I find the non-official Android Libre reader app 'Glimp' useful. Even though I have the official one, I keep both installed, because Glimp does less smoothing/extrapolation of the readings.
