Re:Nuclear Fusion's New Idea: An Off-the-Shelf Stellarator on Wednesday October 30, 2024 @12:19AM (#41991943)
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…
I suppose assthetics is in the eye of the beeholder?

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.

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.
Re:Gitstr: Send and receive Git patches over Nostr on Wednesday January 31, 2024 @05:39AM (#39202213)
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?

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?)

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.)

I should have recognized the username… (Is signal handling even required here?)
Many editors can execute shell commands, so this isn't the same at all.
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.

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?
Hope there's a stronger theory behind that than behind the https://en.wikipedia.org/wiki/EmDrive …
Re:Rust Module System Encourages Bad Practices on Wednesday June 07, 2023 @11:48PM (#36236941)
> 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?

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.

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.)

The opening sentence is really the best part of this thesis.
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?
