Random idea:

volts as Hours amps as Minutes

Resulting wattage drives an iridescent bulb

I think I don't completely understand your idea. The current flowing through the amperemeter¹ depends on the voltage and the resistance of the incandescent(?) lamp. To vary current by the minute, you would need a digital resistor or potentiometer, I guess. Is that your suggestion?

¹) I just found out that it is more commonly called 'ammeter' in English - which is so unintuitive that I prefere 'amperemeter'.

If you have a feedback loop I'm sure you can still do it with an either implicitly or explicitly filtered PWM. Remember we're talking averages not instantaneous, so the average current through the bulb should be proportional to the average voltage across it, though the resistance will change as the bulb heats hence the feedback. You could also do this with a buck/boost regulator and current sense resistor plus op amps to create a constant current supply.

"average current through the bulb should be proportional to the average voltage across it" That is exactly correct, the reason they were seeking clarification, and the core of suggested solution.

V=I*R

If V = Hours and I = Minutes, then by necessity R=Hours/Minutes. Typically a light bulb has mostly fixed resistance (R). Adding a potentiometer to the circuit allows you control the value of R.

So lightbulbs actually dont have fixed resistance. The tempco is pretty big, and temperature of course depends on power (with an annoyingly large time lag when power is reduced).

That being said, the bulb does have a well-defined resistance at a given point in time, so voltage and current are of course not quantities that can be indefinitely controlled.

This falls into the same category as “why isn’t my power supply with voltage and current controls working correctly?!?”

Oh maybe I misunderstood. I thought they meant separate meters, so I didn't understand what was hard about that

Oh - it didn't occur to me that the original poster might have thought about three different circuits - one with a voltmeter, one with an amperemeter, and one driving the light bulb. Maybe that was their intention.

I originally assumed that the bulb would be somehow connected to voltmeter and amperemeter.

I suspect you meant "incandescent".

Iridescence essentially would mean it has a groovy, far-out metallic layer making rainbows on the surface. Not bad, but irrelevant.

PS: Neither of those would really communicate the needed information, except as an extreme (11:59 pm would look just like 10:27 pm, but very different from 12:01 am).

Looks like Mazda 6 to me

You can push to GitHub using Sapling. I wish Sapling open source was given more love, as the experience for non-Facebookers is subpar. No bash completion outside the box, no distro packages, no good help pages, random issues interacting with a Git repo...

Sapling and JJ can sort it out, the outside world will only care for one of them.

I was immediately intrigued when I learned that JJ has revsets [1], just like Mercurial.

> Sounds like what my teachers used to say: “a personal problem”.

They don’t sound like a very good teacher.

Judging by the amount of adults wandering around thinking their personal problems are everyone else’s problem… they were pretty good teachers.

I wonder how their KVM works...

> I must apologise that I haven’t so far open-sourced any part of this that I don’t have to. Mainly that’s because I think this would be an awesomely sticky web property for a printer consumables firm to integrate with their sales site. And I’d much prefer it if they paid me to white-label it for them, rather than just forking a repo and getting it all for free.

They might be interested if they cared at all about the ease of use of their printers

The hardest part would probably be convincing someone to pay to white label something for which most of the key design choices and implementation came from one unfamiliar dev prompting an £18 Claude Code subscription.

Claude was great, but I did put a fair amount of my own time and (non-printing-specific) expertise into this. OTOH, sure, I wouldn’t be asking for a million dollars.

These printer makers have the source code and the ability to write firmware. If they wanted to support WebUSB, they could and would.

Xerox just removed all the Linux drivers first for the majority of older models (even actual ones, which you can still buy), Windows and macOS drivers second for selected models (yet).

Canon, Pantum, Brother, Kyocera, HP, they all still produce new devices on older hardware base, which require driver and does not support AirPrint/Mopria even over USB. They just don't care, they reuse what they wrote 20 years ago and ship it. Xerox and HP use Samsung printing engine and drivers, Pantum uses Lexmark.

They are referring to aftermarket ink cartridge companies, not the printer OEM.

why no X11?

Because everyone's going for Wayland, even though you still need XWayland to do anything useful on it because Wayland is comically incomplete.

well, I mean, why can't this ship with an X server? Or maybe it does and then I'm not sure why it is said that only Haiku apps are supported

It's not that it can't, if you can do something it doesn't mean you should. If we used X it'd be another linux distro isn't it? Part of the fun is to make your own UI feel.

For my daily machine, I need Docker, terminal, Firefox (for private browsing), Chrome (for work), VS Code and/or JetBains IDE. If this can feel a bit like I remember BeOs felt, that'd be awesome

Brilliant way to expose your company's secret data on the Internet :-)

you can put your password to a yubikey, then it's always a long press of a button away

BTW, you can also enable the PW feedback on the classic sudo. I've done that on one of my hosts
