> Recently, GPT informed me that the strong force is really a tiny after-effect of the "QCD force"
Maybe you should not take everything GPT tells you at face value? I have no idea what this QCD force is supposed to be. The strong force is _the_ force of QCD.
The Standard Model still considers the electromagnetic, weak and strong force. The description of the weak and EM force can be unified into the electroweak force and there are theories that try to also unify it with the strong force and even gravity, but there are issues on the theory side and no clear evidence on the experimental side as to which direction is the correct one.
The Standard Model and General Relativity are still our most successful theories. It is clear that they don't tell the whole picture, but (annoyingly?) it is not clear at all where this is going.
Just for dark matter there are probably a dozen proposed hypothetical particles, but so far we have found none. But maybe it's something completely different...
Isn't Incus/LXD separate from and running on top of LXC?
People sometimes seem to use the names interchangeably which can be annoying because I run just plain LXC but when looking stuff up and come across "this is how you do XYZ on LXC" they are actually talking about LXD and it doesn't really apply.
I can't recall what is was last time, but this has happened a couple of times already...
Meanwhile, the DPO4054 I use at work has issues with half of the buttons, the data returned by some commands doesn't match the manual, and the probes from some newer scopes don't fit even though they all just use BNC?
Maybe the software on it is just outdated? Nope, the only version you can get from the Tektronix page is older than what is on the scope. And there are newer versions, but they are only for the DPO4054B and not the older DPO4054...
Right, I'm not surprised. The DPO4054 is a much later machine dating from I think after 2000.
My hands-on experience started with the 535 and it was beautifully built, it was a work of art and I still have a plugin for it. So too were the early solid state ones such as the 453 but they were harder to work on.
In my opinion the 'dream range' was the 7000 series, they were easy to work on and like the 535 the manuals are superb. I've used a lot of that series including the 7834 1ns storage unit with various plugins including the 7L13 spectrum analyzer.
In fact, I've still six functioning 7000 CROs including the 7L13 and about a dozen other plugins. An examination of their PWAs show copyright dates in the early 1970s, so that puts these instruments well over 50 years old and the majority have never needed maintenance other than calibration.
In recent years things have changed. With the advent of much cheaper Asian equipment from Anritsu et al Tek had to change to complete, 'bulletproof' engineering unfortunately had to give way to more modest designs.
Reckon those 50+ year old CROs will outlast me. That quality speaks for itself.

Edit: Their CRO products were always excellent but I cannot say that about Tek's 1411 modular PAL sync pulse and signal generator. The design was good but it had a build fault, the IC sockets had edge-wiping contacts instead of side-wiping ones which often went intermittent. Not good for a sync pulse gen when say a TV station relies on its output for its whole operation (if the sync gen fails, the whole operation goes black).
There's a long story about that unit, it was returned to Tek for repair under warranty and was still intermittent upon return. So I assigned one of my techs—much to his chagrin—to replace every IC socket (hundreds of them) with the best available-Augat's top gold plated range. From then on the 1411 worked perfectly. Sometimes the best of companies produces a bummer.
This brings back memories of my old HP laptop with an Athlon 64 and a Radeon X200M.
The crappy FGLRX driver only supported overlays (afair) and so when running something like Compiz it would transform the window with the green background but the video itself would stay in place and it would just stick parts of the video on top where it happened to overlap.
I still remember being excited when the open source drivers finally gained support for r300 and could do proper textured video...
Can confirm. My 3TB Seagate was the only disk so far (knocking on wood) that died in a way that lost some data. Still managed to make a copy with dd_rescue, but there was a big region that just returned read errors and I ended up with a bunch of corrupt files. Thankfully nothing too important...
> When you send your design to pcbway or jlcpcb they have much tighter control over the process, so you no longer have to worry about this stuff.
Funny that you mention jlcpcb. The last time I submitted a board with tight differential pairs (but still within their listed specs) to them they basically told me to increase the amount of copper, so I assume they had some quality issues in the past:
> we have new rule since Dec, 2022, if the copper areas are less than 30% of the board in each copper layer, the space between trace and trace should be at least 0.15mm to avoid short circuit.
So I had to add a few copper pours and everything was fine :)
And that's one of the benefits of working with a high-volume prototyping service like JLC - they've built a lot of PCBs; they know all about how to maximize yield.
> Including things you like quite a bit, such as WiFi support
A while ago I set up Win 98 on an old P2 laptop from 1998 I found in the trash at work.
Even that can do WiFi with WPA2. It was a pain to set up and requires 3rd party software to establish the connection, but aside from that it works just like any other network card.
You mean Microsoft Windows which dropped support for Zen 1 with Win11 not even 5 years after Zen 1 was released? Meanwhile, Linux will still run on a 30+ year old CPU...
For many old windows games (and probably other apps) you'll actually have better luck running them on linux than a modern version of windows, thanks to wine/proton.
For the sake of nostalgia, I downloaded an Encarta 2000 ISO form Internet Archive, then spun up a Windows 98 VM to run it on but that VM had a lot of sound issues in Virtual Box, then I realized that Encarta would also run just fine installed on Windows 11 lol.
This kind of backwards compatibility is not something I need on a daily basis but it's pretty neat that I can just run very old SW on my main OS without fiddling with VMs.
This is not 100% true. Some legacy Windows software does not run on current Windows. Never got Slave Zero running on Windows XP or Windows 2000 after upgrading from Windows 98 & ME. https://en.wikipedia.org/wiki/Slave_Zero
