I think there's a strong argument that the most useful product from collider science is the synchrotron light source. Researchers using collider rings realized that the x-ray synchrotron light these rings emit (an inconvenience to collider physics people) was a fantastic tool for structural biology and materials science. Eventually, they built dedicated electron storage rings that don't do collisions at all - the main goal is producing bright X-ray beams.
Synchrotron light sources have had wide-ranging, concrete impacts on "industrial products" that you probably use every day via studies in: - Drug discovery (Tamiflu and Paxlovid are good examples) - Battery technology (X-ray studies of how/why batteries degrade over time has lead to better designs) - EUV photolithography techniques - Giant Magetoresistance (Important for high capacity spinning-disk hard drives)
Indeed. The first dedicated light -- for various values of "light" -- source[1] repurposed the tunnel and various bits and techniques from the particle physics accelerator it replaced, and on which parasitic "light" measurements were made previously. See also [2].

> has there been any discovery made with the help of a collider that found its way into an industrial product?
Yes. SLAC has an excellent public-lecture series that touches on industrial uses of particle colliders [1].
If you want a concrete example, "four basic technologies have been developed to generate EUV light sources:" (1) synchrotron radiation, (2) discharge-produced plasma, (3) free-elecron lasers (FELs) and (4) laser-produced plasma [2]. Synchrotrons are circular colliders. FELs came out of linear colliders [3]. (China has them too [4].)
We have modern semiconductors because we built colliders.

In the context of the article "collider" means intersecting particle beams, like in RHIC and LHC, which obviously involves rather low probability interactions, as opposed to accelerators which slam a beam into a dense target (like the SLAC accelerator). In a synchrotron light source you want the beam to circulate and specifically not collide with anything; they were developed from particle physics accelerators, of course.

You imply that experiment contaminated drinking, and other, water. How? Are you saying the Cs¹³⁷ leaked, and at concentration above that from fallout, say? Its γ-rays don't activate materials — I've used enough of them.

as a layperson, it seems the whole collider stuff has not been a very fruitful scientific direction so far (has there been any discovery made with the help of a collider that found its way into an industrial product?)
maybe we are trying to 'jump' the tech tree too much - perhaps the first step was to create a much smarter entity than ourselves, and then letting it have a look at the collider data.
Since when were industrial products the purpose? Why do you think my colleagues can't analyse LHC data and discover the Higgs particle? The article says RHIC was a considerable scientific success.

This is in preparation for starting construction work on the Electron-Ion-Collider (EIC) which will use the same tunnel and experiment locations.
As I recall, RHIC itself replaced some cancelled project. I remember the tunnel being at least partly there in the mid-80s, with a plan to trundle ions from the tandem lab through a crazy long beamline across the site and stop nuclear structure research there as a result.

Good to see. For what it's worth, data were previously available from the Competition and Markets authority, used by https://localfuelprices.co.uk/
Netbird has supposedly done a penetration test, but it is only supplied upon request [0]. I haven't bothered trying to get my hands on it since I don't use their product. I don't agree with gatekeeping the results instead of making them public.
NetBird should also consider publishing an SBOM, similar to what Defguard does.[1].
Oh, I hadn't found that. Yes, it seems strange not to publicize something like that to give users confidence (assuming the audit/pentest isn't damning). It doesn't have to have been perfect initially, as long as appropriate fixes were made.
The only pragmatic use for a modern Algol 68 compiler I can think of would be to port a legacy codebase to a modern system, but any existing Algol 68 codebase will likely see greater porting challenges arising out of the operating system change than from the programming language.
