If you're the licensed user of a given radio band, you can sue people who cause interference. If you're an unlicensed user, you just have to live with it.

For information theory, I've always thought of entropy as follows: "If you had a really smart compression algorithm, how many bits would it take to accurately represent this file?" i.e., Highly repetitive inputs compress well

As someone looking at algorithms for managing buffer bloat, this resonates. In IP routers, the goal is to keep the congested link busy. i.e., Idle time from a momentary hiccup is wasted time. You need a small buffer to do this, but piling o

These are quite clever. I'd love to have my own Borromean Box. That said, I've no clue how to start. It looks simple at first, but seems more complex the more I think about it. Some construction details, videos, or other hints wou

I have never understood why POSIX and NTP timescales work the way they do. They are positively bonkers when it comes to leap seconds. Time isn't even monotonic during the transition, because the epoch itself is redefined. Contrast this

The game "Tabletop Simulator" allows you to spawn various objects into a VR playspace. One of the objects is a tablet PC, which displays a little web browser on its virtual screen. It's handy to look up rules or whatever with

No, not "promising but unproven" at all. This drug failed its clinical trial. It got its chance, and the evidence indicates it doesn't work.

Exactly. It's like mining lead from the bullets flying through an active battlefield. There's material there, but it's moving in different directions.

How much overlap is there between isotope separation technology? The article mentions using centrifuges to separate silicon-28 from -29. Could the same equipment be used to separate uranium-235 from -238? Is this a question of difficulty? O

There was a Swiss startup called Morphotonix that made holographic chocolates [1]. The company and its holographic-imprint tech are still around, but they've moved on to other markets. That suggests they just couldn't get prices l

No information on what kind of energy levels these can achieve? i.e., keV or MeV?

For the "photons per bit" question, the useful throughput of 140 bps is the only thing that matters. For the "how many photons are needed" question, I agree that 320 baud (i.e., the effective analog bandwidth of 320 Hz)

You may be interested in CBOR (IETF RFC 8949). CBOR features are almost one-to-one with JSON, except that the encoding is more size-efficient, it supports a few additional types (e.g., integers and floats are separate), and it allows semant

You have to draw the line somewhere, but I do appreciate when the UI sorts "Book draft 2" before "Book draft 11". That requires nontrivial tokenization logic and inference, but simple heuristics can be right often enough

Perfect is the enemy of good. It is quite acceptable to streamline the easy cases now and the hard cases later or never.

A "law" has been finalized, passed by both halves of Congress, and ratified. A "bill" is an incomplete proposal at any stage of this process. There is a catchy song [1] to help everyone remember this. A bill is the same

This sort of thing is analogous to the "Thompson hack" [1], where a malicious compiler has a self-propagating backdoor. It never shows up in the source code, but self-injects into the binaries. Thompson demonstrated this under con

In terms of cost per ton moved, trains and semi-trucks outperform taxis. And yet taxis still exist. Turns out cost per vehicle (or per reactor) is important in some situations.

No. The moon is tidally locked to the Earth, so its rotation exactly matches its orbital period. If you put a telescope on the far side, it'll always be pointing away from Earth.
