Well, afaik Farnsworth fusor is neither new invention, nor it can achieve over unity. Still a big achievement!

"The incident is raising alarm over the risks of centralized control as governments worldwide push similar schemes."

Good, such things could never happen in the US then./s

But seriously, can we stop such stupid soundbites?

New comment by rini17 in "Debunking Zswap and Zram Myths"

rini17 — Tue, 24 Mar 2026 20:17:26 +0000

You mean zswap part of cleancache? But that fell out of kernel completely, no? And zram gained support for backing device.

BTW most of zram tutorials get it wrong, you are supposed to manually mark idle pages and initiate writeback by periodically writing to /sys/block/zramX/idle and /sys/block/zramX/writeback . Otherwise zram will never ever write anything to backing device. It is documented in kernel docs, just that if you expect it to work automatically you might misread it.

And you can convert swap into such backing device, but then you don't do swapon on it (just remove it from fstab) nor it's necesary to format(mkswap) it.

Kiosk can probably be done with rpi.

It's not only about raw numbers. Others here explain.

New comment by rini17 in "New polymer alloy could solve energy storage challenge"

rini17 — Fri, 27 Feb 2026 16:46:42 +0000

These capacitors are typically used for "energy storage" only in a millisecond timespans. Either to smooth ripples that could damage other parts or to provide surge current where needed. Very very useful but it's not usually referred to as "storage". Article tries to explain the difference to batteries but stops halfway, liable to cause confusion.

Central/Eastern European here. Our labor costs are comparable or even lower than China today. And the manufacturing is still struggling. So it's not only that.

Would be so funny if neurodivergents ended up handling monotony and bland food better than the "psychologically sane (and thoroughly tested) individuals".

And I don't get why food would take so much time from exercise and navigation and that would be a problem. They would exercise 12h daily? In deep space once you reach the trajectory there are weeks or even months without any navigation.

New comment by rini17 in "Cost of copper must rise substantially to meet basic copper needs"

rini17 — Wed, 25 Feb 2026 20:14:55 +0000

Carbon (nano)fiber is competitive with copper conductors if we can mass manufacture it defect-free enough. Synthetic diamond can replace copper coolers, on the other hand. But that needs massive R&D, with experimental aptitude. Not your typical "tech" startup.

New comment by rini17 in "TinyIce: Single-binary Icecast2-compatible server (auto-HTTPS, multi-tenant)"

rini17 — Thu, 19 Feb 2026 08:15:32 +0000

I tried streaming with icecast2 during pandemic and always got dropped connections in tens of minutes. It drove me mad. And it's impossible to detect in advance, receivers skip for seconds till new connection is made. From packet captures it appears as dropped ack packets. It was https so copyright filters are unlikely.

Are there different solutions, different protocols, ideally supported by browser in some simple manner? Is streaming over websocket possible?

New comment by rini17 in "Cosmologically Unique IDs"

rini17 — Wed, 18 Feb 2026 20:21:32 +0000

From real life we know that people prefer to have multiple anonymous IDs, or self-selected handles, either makes fully deterministic generation schemes moot.

Also, network routing requires objects that have multiple addresses.

Physics side of whole thing is funny too, afaik quantum particles require fungibility, i.e. by doxxing atoms you unavoidably change the behavior of the system.

Is there any evidence that the psychiatric care availability alone correlates with improved mental health?

Also psychiatrists should naturally be first to point out the broken system. When that's not top priority for them, no wonder they get villainized.

rini17 — Sun, 15 Feb 2026 13:22:45 +0000

Nice, I'm curious about the orbitals. Is it possible to visualize H2 or larger molecules?

And for me controls obscure the picture, probably because I'm on phone with square screen(Unihertz Titan).

New comment by rini17 in "When internal hostnames are leaked to the clown"

rini17 — Thu, 05 Feb 2026 12:56:54 +0000

Fancy web interfaces are road to hell. Do simplest thing that works. Plain apache or nginx with webdav, basic auth(proven code, minimal attack surface). Maybe firewall with ip_hashlimit on new connections. I have it set to 2/minute and for browser it's actually fine, while moronic bots make new connection for every request. When they improve, there's always fail2ban.

That the nas server incl. hostname is public does not bother me then.

There are 9V NiMHs, too. They just need dedicated charger.

rini17 — Thu, 29 Jan 2026 11:13:01 +0000

There's a research that winter sunlight in northern latitudes just does not convert precursors to vitamin D. Even when it's shining, no matter how long you are outside.

New comment by rini17 in "LED lighting undermines visual performance unless supplemented by wider spectra"

rini17 — Mon, 26 Jan 2026 21:06:16 +0000

Since AC is pulsating you need to store some energy to get continuous DC, usually in a smoothing capacitor. And that capacitor is relatively big and when durable, then not cheap. And it requires some further complications (like avoid inrush current).

Nice. But when I asked it for simple initramfs busybox init script (the usual tools are pure indecipherable bloat) it hallucinated practically on every line. And obviously setting up a VM for it to debug the boot process would be a hassle.

Why my software needs are all like that? Sigh. At least ffmpeg command lines it gets right most of the time.
