I want to replace my aging Synology with an Intel N150 based NUC. I mostly need it for transcoding and to act as an Time-machine NAS for 2 laptops. I tend to larger sized setups so that I can keep them running for 10+ years.

I plan to keep it off the internet. I am planning to go with 16GB ram, 500 GB SSD and then probably attach a 2TB old school hard drive via USB 3.

I am looking for manufacturer recommendations (are there any European options?) as well as OS recommendations.

The irony of this photo — A border patrol 'agent' hiding behind a face covering & hat while scanning a commuter's face on the road.

I am taking the time to post this entire article to highlight how / uses emerging, -breaching tech to identify & target regular people– potentially undocumented individuals AND citizens exercising their 1st Amendment right to express their grievances about such behavior as they observe & record it.

"...at least seven American citizens (were) told by agents this month that they were being recorded with facial recognition technology in & around Minneapolis...None had given consent for their faces to be recorded.

"Facial recognition is just one technology tool that ICE has deployed...
The technologies are being used not only to identify undocumented immigrants but also to track citizens who have protested ICE's presence..."

How ICE Already Knows Who Minneapolis Protesters Are Agents use facial recognition, social media monitoring and other tech tools not only to identify undocumented immigrants but also to track protesters, current and former officials said. https://www.nytimes.com/2026/01/30/technology/tech-ice-facial-recognition-palantir.html Accessed: 2 Feb 2026 at 1226 PSTOn the morning of Jan. 10, Nicole Cleland was in her car trailing an Immigration and Customs Enforcement agent through Richfield, Minn., her hometown. Suddenly, the agent turned into a series of one-way streets and stopped, getting out of his white Dodge Ram, said Ms. Cleland, who volunteers with a local watchdog group that observes the activity of immigration officers. The agent then walked over to Ms. Cleland's car and surprised her by addressing her as Nicole. "He said he had facial recognition and that his body camera was on," said Ms. Cleland, 56, who had not met the agent before. https://www.nytimes.com/2026/01/30/technology/tech-ice-facial-recognition-palantir.html Accessed: 2 Feb 2026 at 1226 PSTMs. Cleland was one of at least seven American citizens told by ICE agents this month that they were being recorded with facial recognition technology in and around Minneapolis, according to local activists and videos posted to social media, which were verified by The New York Times. None had given consent for their faces to be recorded. Facial recognition is just one technology tool that ICE has deployed in Minneapolis, where thousands of agents are conducting a crackdown. The technologies are being used not only to identify undocumented immigrants but also to track citizens who have protested ICE's presence, said three current and former officials of the Department of Homeland Security who were not authorized to discuss confidential matters. https://www.nytimes.com/2026/01/30/technology/tech-ice-facial-recognition-palantir.html Accessed: 2 Feb 2026 at 1226 PSTICE is using two facial recognition programs in Minnesota, they said, including one made by the tech company Clearview AI and a newer program, Mobile Fortify. The agency is also using cellphone and social media tools to monitor people's online activity and potentially hack into phones. And agents are tapping into a database, built by the data analytics company Palantir, that combines government and commercial data to identify realtime locations for individuals they are pursuing, the current and former officials said. "The technologies are being deployed, or appear to be deployed, in a much more aggressive way than we have seen in the past," said Nathan Freed Wessler, a lawyer at the American Civil Liberties Union, which has sued the Homeland Security Department over the immigration operation in Minneapolis. "The conglomeration of all these technologies together is giving the government unprecedented abilities." https://www.nytimes.com/2026/01/30/technology/tech-ice-facial-recognition-palantir.html Accessed: 2 Feb 2026 at 1226 PST

I'm beginning to think ChatGPT is getting pretty smart.

I was reading up on the "Performer" approach to approximating the core matrix multiplications used in attention/transformers in ML [2].

ChatGPT tells me about this:

exp(a.b) = <coh(a),coh(b)>.

At this point it's obviously on crack! coh(a) is a coherent state of a quantum particle as described in [1]. (And <.,.> is the inner product on quantum states.)

But no, after some thought this makes perfect beautiful sense. There's an underlying story about how the "kernel trick" used in ML is very similar to the way physicists like to use propagators to reason about fields. In this particular case, the kernel trick amounts to embedding features for ML in a Fock space 🤯.

I may have dodged a bullet with Notepad++. I've been using it for ages, but it's been years since I've used the built-in updater, because I install it and keep it up-to-date with winget.

Winget isn't a proper package manager, but it's the closest you get on Windows, and downloading packages from a public repo with hashes for verification always beats relying on ad-hoc downloads. That's one of the reasons why the Linux distro packaging model is just better.

Photographer Builds Mini Kodak Kiosk That Actually Prints Photos

PetaPixel | Photography and Camera News @petapixel.com@web.brid.gy

A hand holds a color photo in front of a small yellow and blue Kodak-branded photo printer on a wooden table, with window blinds in the background.

Photographer James Warner, known for his excellent YouTube channel, snappiness, is always taking on new photography projects. They often involve taking things apart and putting them back together in new, exciting ways. Warner's latest project involves building a mini retro Kodak photo printing kiosk for his desk.

The lady who does my nails said something I've been thinking about all weekend

She said something along the lines of "Artists have so much power to move people politically. Its why they want to take our power by telling us AI can 'make art,' but AI can't move people."

She is a great artist imo

So there's a stillMasking family in Ontario whose neighbours have been calling family services on them repeatedly. Every interview was been a nothingburger until they were interviewed by an antimasker who LIED ON THE FORM AND SAID THE KIDS HAD NO FRIENDS AND WERE DEVELOPMENTALLY DELAYED -- at which point the kids were immediately taken away. Somehow they managed to get the their kids back after only a few days (purportedly unheard of), but..

..yknow, in case you wanna know how parents still protecting their kids from sarscov2 are doing

Scientists have created a clock that estimates the time it would take before there was a crash in orbit if satellites couldn’t steer. The current time is 5 and a half days, and it’s only getting shorter. spectrum.ieee.org/kessler-synd

Just discovered part of my HRT has been discontinued due to an AI note taking error. Gynae did not say discontinue, and I have letters to prove it. Now I may have to be without testosterone until this is proven, which may mean another 6 month wait to resee a gynaecologist via NHS. Hopefully my letters will suffice, but currently unclear.

I am beyond furious. Also, wow. Fuck living in this dystopia.

Keep every medical record you get, you're going to need it in this new terrifying timeline.

A screenshot of my medical records that says: • Serum oestradiol level • Summary:; ---- THIS IS GENERATED BY ANNIE (AI) ----; Consultant Gynaecologist advises against continued testosterone prescription due to associated risks.
