The way sentences containing the German character ß get longer when uppercased was specially designed to create memory problems in C programs doing string handling

yeah I'm on fspec (fawn spectrum)

@whitequark what if you're also on the faun spectrum?

it doesn't exactly fill me with confidence that the fools who were supposed to be paying my HMO have apparently lost their DNS server

The worst part of digitization work is having to practice reloading the label printer blindfolded

@sannemen It's just a joke on how you learn to disassemble and reassemble your gun in the military, to the point where you can do it in the dark.

I have to change label rolls so fucking often

Good news everyone! It is NOT radioactive!

@equeroot I'm not going to buy it to find out! I have to draw the line somewhere

Why am I like this

@cadey it's like text adventures. You show up somewhere, you type "look", because you want to know what's going on in here

What about, handheld console that uses floppy discs?

foone,
@foone@digipres.club avatar

@Hundstrasse I want it. I'm gonna build it.

The closest I've seen is that Data Discman which is an ebook reader that uses mini-CD in floppy-like cases

foone,
@foone@digipres.club avatar

@Hundstrasse yeah something like pico-8 would be perfect. Nice tiny games.

foone,
@foone@digipres.club avatar

@Hundstrasse I think I'd want to have pico-8 on the flash, so it doesn't need to load it off floppy each time. Then you'd have plenty of space and quick loading times

one of my least favorite things in computing are progress bars that straight up lie to you until getting to the very end

just make it a puck that goes back and forth and grows bigger as you actually receive data or something

stop fucking lying to me you piece of shit

foone,
@foone@digipres.club avatar

@whitequark I made one of these when I worked for the US government. The progress bar was just faked, the api we had only had a "is it done?" call.
So I programmed it to consistently go up and stall at 95% until it finished.

I'm sorry

@dosnostalgic the weird hardware of the hplx series isn't really emulated yet. I need to scan my technical manual so maybe it can make its way into dosbox

@cyborgurl that's some good numbers. I love protests where it's like a dozen people being protected by police from the thousands of counter-protestors.

So I got this thing at ewaste.

It's a Richtech Automated "AI" Temperature Screening System.

Time to open it up.

Mounted next to the camera is this module, labeled IRT_621_V1.1

I believe this is an i2c thermal camera. It looks very similar to this one, which has a resolution of 16x16:

Here's the weird part that made me think "oh this definitely needs to be a thread": I pulled the heatsink off and cleaned up the CPU module, and it's an HI3516.

foone,
@foone@digipres.club avatar

I thought that this would mean it's just a standard CPU module, but nope! it's specialized.

This is an IP Camera!

It's an Arm Cortex A9, up to 800mhz. It can encode H.264 or MJPEG.
It can do face detection.
Apparently it is based on Linux 2.6.35?
It just needs some magnetics to talk ethernet and it can do wifi over USB or SDIO

Two half-gigabyte K4B4G1646E DDR3 chips from Samsung

And another Samsung chip: A 4 gigabyte KLM4G1FETE eMMC chip

MXC MX35LF1GE4AB: 128 megabytes of serial flash.

@foone@digipres.club avatar

TMSEMI TMS1102NL:
This is the ethernet magnetics, so this thing is ready to go for wired networking

foone,
@foone@digipres.club avatar

And the only major chip on the big PCB is a Unisonic Technology MC34118, which is a voice switched speaker-phone circuit. So it's got some audio amps and automatic gain control.

foone,
@foone@digipres.club avatar

This thing has a speaker but no mic that I see.
And I guess that IP camera module has video output?

foone,
@foone@digipres.club avatar

Forgot to mention this chip:
Realtek RTL8201F. That's a 10/100 ethernet chip.
