casparvitch··on Researchers develop molecular qubits that communicate at telecom frequencies
Always cool to see stuff from your niche field on hn. Note: this measurement is done at cryogenic temperatures, although somewhat similar molecular spin work (from ~same group [1]) works at ambient.

casparvitch··on Solveit – A course and platform for solving problems with code
I'm slightly confused. From your comment I expected an AI chat tool, but solveit appears to be more a class?
casparvitch··on Rio Terminal: A hardware-accelerated GPU terminal emulator
Yeah I understand all the flashy bits in kitty, but do you need GPU levels of speed? `foot` is much faster than my typing/brain in all cases.
casparvitch··on Top US researchers rush to relocate to Europe
> 'their own issues not unlike the US'

I find this kind of opinion hard to understand. The difference is incredibly high contrast to me.

casparvitch··on Rio Terminal: A hardware-accelerated GPU terminal emulator
Does anyone get anything out of these GPU accelerated terminals? I am at a bit of a loss for a use-case where my CPU isn't fast enough to keep up.

What I do care about is my bitmap font, which all these new terms don't seem to like supporting.

casparvitch··on Slack has raised our charges by $195k per year
Sure, but COMSOL does a lot of work for you you couldn't achieve otherwise - I find it hard to see glorified irc (slack) as ever being worth $200k a year!!!
casparvitch··on Half an year on Alpine: just musl aside
The MNT SoC (etc) drivers are still not up upstreamed, so think you're stuck on debian for a while
casparvitch··on How I code with AI on a budget/free
At that(/what) point does it become harder for a human to grok a project?
casparvitch··on Python performance myths and fairy tales
I think you're referring to the TTFP (time to first plot) issue (the package manager is top notch). TTFP has been drastically improved with a bunch of optimisations, and then you can pre-compile your project to keep it fast e.g. between running your script with different params.
casparvitch··on Show HN: HackerNews but for research papers
Top journals have good research in them, they cannot be bought like that. The downside is that they get caught in the hype, and only publish articles likely to be more glossy.

The way to clean garbage from gems is to spend half a decade plus in grad school (literally).

If you just want to enjoy reading about the latest & greatest in science, then Science & Nature are good reading. But for any real perspective you need to read non-academic writing from those researchers willing to exert that effort.

casparvitch··on Show HN: HackerNews but for research papers
If the return isn't there for career scientists, and it takes them 4-6hrs to read a paper properly, then can non-specialists really get much out of the process?
casparvitch··on No Tech for Apartheid
'bad thing and killing have happened throughout history and thus cannot be critiqued'
casparvitch··on C Is Not a Low-level Language (2018)
Forth/joy maybe?
casparvitch··on Nobel Prize in Physics Awarded to Agostini, Krausz, and L’Huillier
I can vouch, I'm in a heavily particle/astro dominated dept and AMO is looked down upon.
casparvitch··on Earth beyond six of nine planetary boundaries
One and the same, economic growth has lead us here & economic growth has been highly tied to population growth.
casparvitch··on Tidal energy is not renewable
If HN was reading Murphy the front page would look very different every day
casparvitch··on Fourteen days across the Atlantic, perched on a ship’s rudder
You say stupid stunt, they say an attempt at finding a better life.
casparvitch··on Anchor Brewing Was San Francisco
Apologies but this is such a hilarious Americanism: "If it's not ethnic it's German"
casparvitch··on SUSE is forking RHEL
So sick of CPUs in Linux distros, the feature creep is insane!
casparvitch··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
They are! And they receive fewer funds in my neck of the woods.
casparvitch··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
I get that. Perhaps things are different in different countries, but where I am materials science/eng is drastically underfunded for this reason.

My comment was worded strongly, I meant more that funding could come from different streams fo4 different purposes.

casparvitch··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
Fair enough. The point of my comment was the incentives are set up in 'science' to research fundamentals (I don't think there are many interesting fundamentals in degradation, but I may be wrong). I am arguing there should be a separate stream of funding/researchers with incentives to work on other types of problems.

Scientists tend to be interested in 'neat cool solutions' or 'neat cool problems' and there should be separate funding for 'important problems with boring solutions' that sits separately to current science funding. I agree leave the small-scale iteration to industry.

casparvitch··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
There is no agreed upon definition of science or the scientific method. I'm sure we could agree upon a demarcation between scientist and engineer, though, and I was drawing that distinction in a way I think we can all intuit.
casparvitch··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
I disagree that science has the wrong incentives. The place for science is to chase new (e.g.) physics, not build something useful.

As a society we have decided that (e.g.) physics should/shall solve our problems with better technology. But that is not what pure academic science is about, or what pure academic scientists care about.

You want to iteratively improve technologies? Give more funding to proper engineers, not physicists/chemists, even if they're sometimes in the 'school of electrical engineering'.

casparvitch··on From Common Lisp to Julia
Pluto is the best notebook system I've used, and development is very rapid so it's getting better all the time.
casparvitch··on Wait vs. Interrupt Culture
Have you found any patterns to the people in these two groups? I find that older (50+) people are far more likely to get upset with my interruptions.
casparvitch··on Ask HN: How did you stop drinking?
I had the same transition process from omnivore -> vegetarian and vegetarian -> vegan. It was hard at first, largely because of ingrained habit, but it gradually became revulsion as you describe. You have motivated me to try sobriety, thanks.
casparvitch··on Mysteries the Standard Model can’t explain
No, physicists are pretty comfortable with that one. It isn't immediately intuitive, but the models we have are powerful and predictive. There is of course a somewhat open question as to the interpretation of quantum mechanics. That question is almost metaphysics, whereas the problems quoted in the article are more holes in our present theory.

Errrrr no it doesn't?
