@Lee_Holmes 4.5 might be a little young for a cloud chamber.

But I'll definitely play with one later on

We've looked at absorbance spectra of a bunch of magnatiles but she doesn't quite get all the details I'm trying to explain.

The joys of trying to teach a preschooler physics lol. (Having Paisley's Corner playing in the background was also a bit of a distraction but she insisted)

Comparing spectra of the incandescent and white LED bulbs

Fine tuning the Lego spectrometer more.

Using a maglite as the source eliminates the need for a separate collimating lens.

I also switched away from the very flaky variable slit made of a sliding brick that wouldn't stay in place if you looked at it wrong.

After some failed experiments with aluminum foil, I discovered that the round tree trunk Duplo brick was a tiny bit smaller than a nominal square 2x2 brick. When placed next to a square brick and locked in place with a plate on top you get a very consistent, repeatable slit that I'd ballpark as somewhere around 200 μm.

@nicole ELIZA is probably a better therapist than a LLM.

@petrillic please do. It's awful and needs to go.

Some screenshots of a game engine I was working on in my teens.

The test game was a spoof FPS set in my local community using super soakers instead of real weapons.

All OpenGL and MFC based. Blast from the past lol. I taught myself x86 assembly writing SSE geometry transformation routines.

Paper I wrote as an undergrad

Random photoresist datasheet

Why is bob ross juice a thing

@byte the cockroaches will be IRCing over HF radio after whatever apocalypse wipes out humanity.

It's the messenger that will outlive all others. Like cockroaches it's not pretty but also nearly impossible to kill.

@aeva the other thing is wayland (and X) did it all wrong architecturally. If you really want to reimagine the display stack make the *app* the server.

By default when launched it'll send some ipc request for the local session client to connect to it.

But you can also port forward to it over ssh or whatever to get first class app remoting, including multiple concurrent seats connected to one app server at once. If the last connection drops the app simply becomes headless until the next time a client reattaches to it.

Good luck getting app devs on board with *that* model though.

@aeva i agree, the only way it'll work is if at *minimum* all of the desktop compositors (forget about weirdo embedded /VR ones nobody writing general purpose apps cares about them) define a standard set of protocols that they all support and that apps can assume are available.

Better yet, standardize on implementation of them in a common library.

@aeva the best wayland is 2035 wayland when they've finally got all the bugs ironed out and implemented all the obviously necessary protocols that some core dev decided didn't fit his ideology but then he retired and everyone else went and did what had to be done all along

@thegaffer @pluralistic The shooting sports community has been working for years to do something similar, replacing the term "accidental discharge" with "negligent discharge" to reflect the fact that barring extremely rare mechanical malfunctions, guns don't just go off on their own.

If it fires without you intending, it's because you were doing something stupid and dangerous like having it loaded when you shouldn't have, leaving your finger on the trigger, etc.

So just like with a significant number of car crashes, it's not an accident it's negligent behavior on the part of the operator. This sort of terminology should become more prevalent in general.

My daughter just yelled "shark attack" and threw a blahaj at me.

Clearly we've trained her well

@ireneista is there any way to offline repair? Like on a debian box you can mount the root fs, chroot it, and apt reinstall something
