lokl··on A toxic, nightmarish lake created by our thirst for tech
Who is investing in R&D of less toxic methods of refining rare earths?
lokl··on The Nobel Peace Prize 2020
I was helping these people with a different type of need (non-life-threatening), then later the food security situation developed and nobody else seemed to be able/willing to help, so I changed my focus. As I imagine is often the case where WFP is concerned, the population was especially vulnerable due to pre-existing medical conditions.
lokl··on The Nobel Peace Prize 2020
When I unexpectedly found myself responsible for feeding 100 people at imminent risk of starvation, half way around the world, WFP made it happen. Not only did they make an urgent delivery, they paved the way for a partnership with the Food and Agriculture Organization to set up a sustainable way for the people to feed themselves long-term (chickens: eggs to eat and to sell to buy other food). When talking about food security, even small numbers like this have an enormous impact, and it is truly mind-boggling to consider the overall impact of their work.
lokl··on Differentiable Dithering
Might be better with CIELAB color space, where "difference" is closer to "perceptual difference."
lokl··on AresDB: Uber's GPU-Powered Open Source, Real-Time Analytics Engine
Thanks!
lokl··on AresDB: Uber's GPU-Powered Open Source, Real-Time Analytics Engine
What are the best case scenarios (roughly) for GPU-based speedups of typical DB workloads? I have no sense of whether we're aiming for 2x, 10x, 1.1x.
lokl··on Discovery of scholar's notes shine light on race to decipher Rosetta Stone
I am impressed by many artifacts of ancient civilizations (including the Rosetta Stone), but the museum object that has given me the strongest feeling in person is only 40 years old and it's just plywood and simple words. If you have a chance to visit Gdansk, I recommend the European Solidarity Centre. Another example where "No reproductions or photographs can do it justice or compare to seeing history right in front of you."
lokl··on Interview with Zig language creator Andrew Kelley [video]
Zig is appealing to me, but I wonder whether time spent mastering Zig would be better spent mastering C.
lokl··on VTM: A Text-Based Desktop Environment
The source might not be there, yet, but the MIT License is in the repo.
lokl··on Having an alter ego can reduce anxiety, benefit confidence: research
It was initially unwanted, but it became interesting because it lasted so long. What made it possible was that we didn't work closely (different groups) and encountered each other only infrequently and usually one-on-one, so there weren't others around to correct him. When I left, there was a social event with mainly people from my group, so he was not present, and I don't actually know whether he ever learned of his error. Maybe my alter ego still lives in his memory.
lokl··on Parsing S-expressions in C (2019)
Why not make parsing S-expressions the game? HN crowd would love to play.
lokl··on Having an alter ego can reduce anxiety, benefit confidence: research
I had an unwanted alter ego once. A colleague called me by the wrong name for the entire time we worked together (a few months). I considered correcting him, but I wanted to see how it would play out.
lokl··on The Market for Discontinued Photographic Film
An option not yet mentioned in the comments, if you shoot sheet film, is to use X-ray film, possibly cut to the size you need.
lokl··on 'Music is as good as gold or oil': A man spending billions on old hits
Some literary agencies operate like this. They make most of their revenue from a small number of authors. In some ways, literary agencies already are "YC for budding young novelists."
lokl··on Chemists create the brightest-ever fluorescent materials
The article says, "there are currently more than 100,000 different fluorescent dyes available." How can I learn which are the most lightfast?
lokl··on 1SecondPainting: Generate abstract paintings in one click
Not all abstract art. Some Kandinsky, for example, is more than decoration to me.
lokl··on 1SecondPainting: Generate abstract paintings in one click
I feel the same way about many human-produced works, regardless of critics' views, so the fact that I'm aware these are produced by NN is probably not the only explanation.
lokl··on 1SecondPainting: Generate abstract paintings in one click
I think AI is currently able to generate images I find pleasant to look at, but they have no impact on me beyond that momentary enjoyment. It is still decoration and not yet art, according to my personal definitions.

When I can tell an AI to make an image about the Spanish Civil War and it produces Guernica, then I will be impressed in the way human artists impress me. And then we will have a powerful new tool to communicate. I would like my own personal Guernica each day to help me learn about something happening in the world.

lokl··on Apple commits to be 100% carbon neutral for supply chain and products by 2030
If they're serious about reducing their pollution, they'll give more consideration to the end of the product life cycle.
lokl··on Things Unexpectedly Named After People
Southern blot, but not western blot.
lokl··on Almost one-third of Florida children tested are positive for the coronavirus
We are tracking cases, hospitalizations, ICU beds, deaths, but it is too early to track long-term health problems. I think it would be beneficial if there were more public discussion by experts about the implications of not knowing the long-term consequences of infection.
lokl··on Google offers free fabbing for 130nm open-source chips
Could this be suitable for a camera sensor? I don't know anything about hardware, but I am intrigued by the idea of exploring new camera sensor ideas.

Edit: Nevermind, another comment says 10 mm^2 per project. That's probably too small for the type of camera sensor I have in mind.

lokl··on Show HN: HiFiC – High-Fidelity Generative Image Compression – demo and paper
Has this been extended to video (beyond compressing each frame separately)?
lokl··on The Power of Crossed Brain Wires: Synesthesia makes ordinary life marvelous
I experience a rather boring form of this, sight inducing touch sensations. It can be uncomfortable to look at some things because of the association. Otherwise, very little impact that I'm aware of. So, it's not all about the color of music and numbers and memory aids.
lokl··on Roman mosaic floor found under Italian vineyard
+1 for Time Team. Highly recommended for HN readers even remotely interested in archaeology.
lokl··on OpenBSD 6.7
Thanks!
lokl··on OpenBSD 6.7
Where can I find a recent unbiased analysis of OpenBSD vs Debian security?
lokl··on Why is the stock market rallying when the economy is so bad?
I am also concerned about this, especially medical costs. What alternatives better track this type of inflation?
lokl··on Why is the stock market rallying when the economy is so bad?
Several comments here about alternatives to stock, the poor returns of bonds, and cash being eaten by inflation. If you've been thinking about this and are a U.S. investor, read about I Bonds. Or, if you aren't worried about inflation and are investing for 20+ years from now, don't forget about EE Bonds.
lokl··on Elon Musk: ‘Too many smart people go into finance and law’
I'd like to see more go into politics.
