wenn man unbekannten tee kauft, weiß man ja nie genau, ob er wirklich gut schmecken wird [wenn man ihn nicht probieren kann]. der letztes jahr auf dem weg nach england in den niederlanden gekaufte tee aus italien mit hübschem namen hat sich jetzt als lecker herausgestellt. 😊

Abstract: We report on the implementation of a radiotracer photoluminescence spectroscopy setup at the ISOLDE radioactive ion beam facility at CERN, enabling element-specific identification of optically active defects in solids. The method combines radioactive ion implantation with optical spectroscopy, allowing the temporal evolution of photoluminescence signals to be correlated directly with nuclear decay. The setup is currently optimized for color centers in diamond and related wide-bandgap materials and enables room-temperature measurements. The system consists of an optical microscope coupled to a fiber-fed Czerny-Turner spectrometer with a liquid-nitrogen-cooled CCD detector, providing the stability required for long-duration measurements. As a proof-of-principle, radioactive $^{75}$Ga was implanted into diamond as a precursor to produce $^{75}$Ge impurities. The photoluminescence band extending from 600 nm, corresponding to the well-known GeV$^{-}$ center, exhibits an exponential decay with a half-life of $82.3^{ 2.5}_{-2.3} \mathrm{min}$, in agreement with the known $\beta^{-}$ decay half-life of $^{75}$Ge of $82.78(4) \mathrm{min}$. This establishes a direct and unambiguous correlation between the observed spectral feature and its germanium origin. These results demonstrate the capability of the setup to perform element-specific optical spectroscopy and extend radiotracer methods to color centers in wide-bandgap materials, taking advantage of the uniquely broad range of radioactive isotopes available at ISOLDE.

Little tip when linking to source code in your docs, etc.
You can link directly to lines using anchors if the web view of your source control system supports it. e.g., for Codeberg:

Someone really needs to try tieing this audio->drummer motion system (From Disney research) to one of the new humanoid robots and close the loop:

So, seems I have a new job lined up finally as I've signed the tentative offer letter. Also, still working with Zig and made progress with grabbing information from the Linux `sys` tree for sector/logical block sizes. Been a busy yet awesome day.

Substack screwed up with its AI detection system, and it's making a lot of people leave. But it's a symptom of a bigger problem. I've said before that AI accusations are the modern equivalent of "She's a witch."

The detectors don’t work, the people who built them admit they don’t work, and careers are being wrecked by them anyway.

One of my biggest disappointments was always not seeing Rush live while Neil Peart was alive. I almost passed on this tour, but tickets for the second Cleveland show came down in price at the last moment and I realized that I'd never forgive myself if I didn't go. So after leaving work early and braving the downtown Cleveland traffic I actually managed to find on street parking and go see one of the best concerts that I've ever been to.
I thought the first set was amazing. …

Working in computer security, I've learned to be *real fucking careful* about this law and have heard of it being interpreted *very broadly.* If a client of mine described a system to circumvent access restrictions like this I would fire them. But assuming I didn't fire them, I would
1) tell them to shut it down immediately
2) tell them to talk to a lawyer.
LLMs, as a class of user, are clearly not authorized to access the information. By circumventing access controls, they have "knowingly accessed a computer without authorization." Those access restrictions exist to protect against various damages, including bandwidth use and "intellectual property theft" (another concept I'm not a fan of, but anyway). By violating those restrictions they could open themselves up to legal liability.
Now, IANAL. My job is to describe risk. That's a sufficient risk. It actually doesn't even matter if you'd win the case in the end, a lot of people just can't afford to fight.
But, in this case, it tends to be powerful people, for whom the law does not apply, abusing people who neither have the protection of the law nor the money to just ruin someone's life with a flood of lawyers.
