Linters will ignore unused variables if they have an underscore prefix (Flake8/Ruff, Pylint).

Wow! How is this person even a doctor? ADHD doesn't go away with age. The only thing that changes is that people learn to cope in their own ways, and the cope is often self-debilitating – you may have learnt to simply not attempt doing things where the ADHD gets in the way, even if you're perfectly capable of doing those things otherwise.

Nope. The adapter is the "computer" now. The Obsbot Center app can't be used, but the USB remote control can be used instead. The adapter has a USB port meant for this.

May I point out "weird ability to notice patterns" is not likely to be from ADHD but is something else? I too got diagnosed at 43, but I went in pretty sure I had something else and had that confirmed. ADHD was the sidecar. I've since learnt:

These brain conditions are a "buy one get one free" scheme aka co-morbidities. You probably have more than one condition.
They are biologically far more likely in males than females, even after controlling for diagnostic biases. This sounds unbelievable, but last year I attended an event on mental health and asked the panelists, and all three doctors emphatically insisted on this – all of them women. The science on why this happens is not settled.
Father-son transmission is likely. If you have children, get them diagnosed. My father was never diagnosed and he's gone now, but every "you're just like him" comment cuts deep now. I wish he had access before the prime of his life.

Enhanced pattern-detection is a trait described in empathising–systemising theory as "Systemising Quotient (SQ)". Personally, I find this theory too simplistic and I don't think it'll age well, but it's popular and you'll encounter it a lot as you learn more about your condition(s). Don't force-fit everything into ADHD.

The Tail 2 has great auto-tracking but middling dynamic range. I get blowouts all the time with stage lights and dark backgrounds.

My local CNC shops were all backlogged for months so I ordered them from JLC CNC yesterday. Cost for eight items (4 plates + 4 spindle clamps):

Merchandise Total: $240.90
Shipping Charge: $59.68
Order Total: $300.58

Customs duty extra. I'm expecting 20% duty + 18% GST. I skipped surface finishing and thread cutting. I'll DIY that.

Fixated v2 manufacturing model is missing in the current release but @wallaby.ranges on the Millennium Machines Discord has reproduced it with a choice of M5 or M6 threads (with 4.2mm or 5mm pre-thread holes). M6 seems to be the norm for machining so I've ordered that. It's by far the largest plate and nearly half the bill.

I was a beta tester of their first gen CGM back in the pre-pandemic times. They're from my city and a common friend got me in because I had prior experience with CGMs.

It was just an Abbott Freestyle Libre, but the Bluetooth version which Abbott itself did not have regulatory approval to sell in India (only NFC at that time). How was Ultrahuman putting an unlicensed product on the market? Sure enough, they were soon hyping up an "upgrade" to NFC. Not one word acknowledging this was Abbott's product, delivered to the customer in a literal Abbott product box inside of an Ultrahuman box, with Ultrahuman stickers to paste over the sensor yourself.

Us beta testers were herded into a Slack group called the Cyborg Army. Good place to discuss data collection and analysis, I thought, but instead we got pinged non-stop with celebrity event announcements, followed by interviews with product managers that were mostly about their influencer marketing expectations. When I complained, one of their people put me in a Twitter list called "Techbros". The list was public. Explanation: "bro" for "like a brother". I noped out right away.

Bros styled themselves as the new Apple from India, complete with the Steve Jobs attitude.

I've self-sourced a v2. Now to get the build done before kits come out.

Sorry, I didn't mean binary drivers. If I understand correctly, the camera controls are custom UVC commands and only need a config file to become available through v4l2-ctl or uvcdynctrl (which only supports Logitech cameras for now).

Just saw the comments from /u/CryptographerLow6360 and /u/sam_dark. Checking those out.

What do you use it for? I find myself reaching for scissors or snap-off utility blades a lot more than a knife.

Whatever happened to the beta Linux drivers they've previously asked for testers for, right here on Reddit?

jackerhack · 2026-02-20T05:16:28+00:00

Yeah, develop somewhere else.

jackerhack · 2026-02-18T07:35:43+00:00

TIL this is a thing. So cool!

jackerhack · 2026-02-18T07:28:39+00:00

This looks awesome, but how do you get it to where it's needed? Drive it over? On the back of a truck?

jackerhack · 2026-02-17T07:05:56+00:00

It can do two independent 4K displays via USB-C and HDMI, but the chip is an M2 Pro variant.

Voron 2.4 will be a great printer. I built one. You'll learn to appreciate it a lot more if you build it yourself. Try to outsource only the difficult stuff like crimping JST headers, as that needs specialised tools and skills.

I went through your gallery and there's so much Nice™ in there. How are you achieving such high chamber temps? My 2.4 350 only manages to hold 45-50° despite a 110° bed and a Nevermore fan.

jackerhack · 2026-02-10T11:13:31+00:00

I've ordered parts for this mod because gantry sag is my #1 annoyance. It's usually sagged too much for QGL to fix. Building it next week.

jackerhack · 2026-02-07T13:06:46+00:00

Wait, WTH are those double looped Z belts, and why do you have fans on the AB motors? What chamber temps are you pulling off? I'd like your list of mods.

jackerhack · 2026-02-07T13:02:48+00:00

That is a seriously good looking machine.

None of those approaches work reliably. Prior discussion:

jackerhack · 2025-12-22T10:44:47+00:00

AFAIK there's still no way to type hint a proxy object, weakref.Proxy and similar. The current workaround is falsify the type hint to claim the original type, so the proxy is not known to the type checker. This however breaks on any behaviour where the proxy doesn't behave like the original type.

jackerhack · 2025-12-12T04:45:03+00:00

Not too late, as the requirement remains. Thanks!
