liftm··on Nuclear Fusion's New Idea: An Off-the-Shelf Stellarator
I'm a physics layman, and I'm having some trouble with uniting the content of your comment with the fact that existing magnetic confinement experiments have reported maintaining a plasma at the right temperature for longer times (not with fusion, but with microwave heating, and with the power of those heaters in the 10MW range).

Have I understood the consequences of those reports wrong? Does the heat loss you talk about only occur with fusion? (And if so, is it even a problem if the conditions for fusion to occur can be created by external heating this "easily"?)

I'll assume the inlet is below water level / at the bottom of the tank…
liftm··on "Strong focus on aesthetics" contributed to collapse of Norway timber bridge
I suppose assthetics is in the eye of the beeholder?
liftm··on Show HN: Workflow orchestrator in Golang
Argh, using this would cause name collisions in my brain. https://github.com/agersant/polaris/ ^^
liftm··on Firsty.app – free 300kbit/s eSIM for US/EU
Guess my IoT devices will have to learn how to watch videos.
liftm··on DVD's New Cousin Can Store More Than a Petabit
> Who says we need to fill it up in a reasonable time frame?

So you yourself are saying anything longer than a month is unreasonable?

In any case, this lab experiment will need much improvement in speed and energy requirements.

liftm··on DVD's New Cousin Can Store More Than a Petabit
At 75 MB/s, this thing takes 30 days to fill. How much slower would you like?

liftm··on Translating OpenStreetMap data to HTML5 Canvas with Rust and WebAssembly
Well, if you're playing with wasm like this post, you could sidestep canvas and render the image on the wasm side. c.f. https://github.com/plotters-rs/plotters-wasm-demo
liftm··on Show HN: Multi-monitor KVM using just a USB switch
My monitor doesn't have dcc. I've worked around that part by activating automatic input selection and xset dpms force off'ing on the device I want to switch away from.
liftm··on Gitstr: Send and receive Git patches over Nostr
Can anyone compare this to https://radicle.xyz/? (Or am I wrong thinking they're similar? I've used neither.)

I suppose gitstr would have the benefit that you'd already have the public key of whatever person you'd want to send the patches to? Because you learned of the existence of their repos via nostr, or so?

liftm··on Future gigantic solar farms might impact solar power elsewhere in the world
Good to know. In case Astrophage ever comes visiting us.
liftm··on Zeiss's "Holocam" turns glass windows into cameras
I did mostly think that. So what's the thing in the glass that gets hit like the "another pool ball"?

liftm··on HTML attributes for improved accessibility and user experience
How does this help accessibility, though? (Maybe I don't know enough about HTML. Is the usual way to produce a descending enumeration to write the elements in reverse order and then re-reverse them in CSS or so, which makes them be read wrong by screen readers?)
liftm··on Hashmaps in Factor are faster than in Zig
It's surprisingly common for fledgling programming languages… cough https://accidentallyquadratic.tumblr.com/post/153545455987/r...

(I know https://news.ycombinator.com/item?id=38138223, but at least I'm not the first one this time.)

liftm··on As I retire, my goal now is to release 40+ years of source code
I should have recognized the username… (Is signal handling even required here?)
liftm··on The first stable release of a memory safe sudo implementation
Many editors can execute shell commands, so this isn't the same at all.
liftm··on As I retire, my goal now is to release 40+ years of source code
I've seen this attitude before. In that specific case, someone tried to not depend on the signal_hook crate and manually (unsafely) implement signal handling… without knowing that there's a ton of pitfalls to it.

(The signal_hook crate even contains documentation on those pitfalls. https://docs.rs/signal-hook-registry/1.4.1/signal_hook_regis...)

I mean sure, reinvent the wheel. But it might do good to at least have an inkling what those 105 dependencies for your http listener did.

Apply this tool in reverse and live fast and dangerous?
liftm··on Nickel Hydrogen Batteries by NASA
I laughed, but is that really true? You're going to have a lot of batteries/cells in one place, and one will inevitably start barbecue. Isn't the question whether the rest joins?
liftm··on 'Unbelievable': Astronomer Claims 'Direct Evidence' of Gravity Breaking Down

liftm··on Rust module system encourages bad practices
> A go mod download equivalent would be nice so that we can actually reliably cache dependencies in ci.

What does go mod download do? cargo fetch/cargo vendor don't do the trick?

liftm··on The NixOS Foundation’s Call to Action: S3 Costs Require Community Support
Just for my understanding: That wouldn't help, right?

- It doesn't change storage costs

- It doesn't decrease the cost of a full exit

- They already have a CDN in front of it which reduces the traffic by a factor of 60.

liftm··on Nobody cares about our concurrency control research [pdf]
Should have a (2017) in the title?

(I was doing student assistant jobs for a database research group in 2015. This was old news even in 2017 (though I suppose nobody put it quite so obviously). I'd be curious if anything changed since then.)

I suspect they also don't have an API to check the orders you sent?

The opening sentence is really the best part of this thesis.
liftm··on Correlation between the use of swearwords and code quality in open source code? [pdf]
https://words.filippo.io/dispatches/whoami-updated/ found a way to enumerate all github users. Shouldn't be too hard to enumerate all repos from there, count stars, and check the pareto distribution assumption?
