As many of you know, I very much enjoy classical music. I have many favorites. One of those is the William Tell Overture by Gioachino Rossini – a portion of which was used at the as the theme music for the TV series “The Lone Ranger” in the 50’s and 60’s.
Recently I encountered a concert hall version of this piece that took a very entertaining approach to that classical work. For those of you who remember The Lone Ranger (and everyone else as well) I encourage you to click on the embedded link – to both enjoy the music as well as the humor.

And please, tell me what you think about this performance. 😄

Abstract: Compact Free-Electron Lasers (FELs) offering broad, continuous spectral tunability are traditionally constrained by fixed-parameter magnetic structures and the necessity for high-energy electron beams. High-gain Harmonic Lasing (HL) has long been proposed as a solution to overcome these limitations; however, a robust experimental verification of this principle has remained absent. Here, we report the first experimental demonstration of high-gain HL. By employing a frequency-tunable electron beam density modulation to dominate the fundamental instability, we achieved sustained FEL amplification at the 3rd and 5th harmonics of the wiggler. The HL mode generated output power comparable to conventional fundamental operation with enhanced stability and narrower spectral bandwidth. Notably, we demonstrate that HL extends the spectral coverage by a factor of two under fixed facility constraints, achieving pulse energies up to 540 {\mu}J. These results establish high-gain HL as a versatile mechanism for advancing compact, wavelength-flexible FEL facilities.

So, spent most of the day getting Handbrake compiled with the `svt-av1-psyex` and `svt-av1-essential` forks of the SvtAv1 encoder. However, I did win that battle and both are now available in the `sisyphus-client` containers. Definitely a pain in the ass, but it's nice to have options depending on what you want to use. Also updated the documentation to make sure I don't forget which is which.
I still need to implement some pipelines to build these, but holy crap the Handbrak…

amazing piece but basically woke up in the middle of the night wondering about the unanswered question here: if book freak richard hell has been in the same wee spot since '74, what does he do when his shelves are full? does he have storage spaces like verlaine? does he deaccession at the strand? #nyc #books

Hah! I win, I can talk about video games as well!

Wat al heel lang geldt wordt vooral maar weer eens duidelijk: koop biologische groenten.
Het meten in twee maten bij de overheid zal niet snel overgaan en de oplossing van de fabrikanten van babyvoeding is wel zo eenvoudig en toepasbaar. -mits supermarkten het ook biologisch aanbieden-

Things I have learned over the last two days consolidating all the VMs in the homelab to the same OS:
- Plex is absolutely horrible and hates NFS. It also hates you.
- Docker volumes are annoying as hell, but easy to deal with if you know how to get the data out of the volumes. If you're rocking a lot of them it will be a pain to move them to another server.
- Forgejo actions are also a pain in the ass.
- Moving my `step-ca` information from one server to another wa…

A reminder for those in Ottawa and Ontario...
Upcoming municipal elections will be October 26, 2026.
You can check to see if you are on the voter list. It takes at most 2 minutes.
The last election it took us maybe 10 minutes and they made sure handicapped voters had everything they needed.
If you don't vote then DON'T BITCH!
