@foone imhex fuckin' rules though tbf

@foone you are going to love the pattern scripting thing. it's *so* good. like, "I wrote a PE parser in it on day 1 of using the tool" level of capable and well-enough-documented.

genuinely thought you were going to describe a Stronghold Crusader deckbuilding game there

I recently found out that my department at work is being shut down, so I'm looking for a new position!

I spent the last 6 years building advanced security assessment capabilities around hardware/IoT, industrial, marine OT, and x86 platforms. Before that I spent 5 years as a pentester. I excel at weird and novel stuff where there's no template.

I'm based in the UK and I'm looking for a remote full-time role.

@mntmn what kinda of UPS do you get in-game? (press F4, tick show-fps.)

that's going to be critical as to whether it's playable, since it directly affects factory performance.

@mntmn I appreciate any and all efforts to try to make VUSB not utterly shit. normally the only thing worse is automotive 12V.

@mntmn on that note, I genuinely wonder if it makes sense to calibrate your VUSB buck converter's output voltage to somewhere near the highest level you can get before its upper regulation tolerance would exceed the USB spec. so if you've got ±1% on your buck and the spec is ±5%, aim for something like +3% (5.15V) to compensate for all the parasitics in the cable.

@mntmn is the dupont something many end-users are already set up and working with? changing the connector to one where they need to buy an additional cable might be annoying if that's the case. especially if you then need to document "on rev X we changed it for this other connector, you need to check which you need".

if it's not something folks are really using much, then switching to a nicer connector should be ok.

@mntmn have you ever tried to source conductive glass? I've been looking into it recently (both sputtered and copper mesh) but I haven't been able to find a reference price (like, not even an order of magnitude)

@jacqueline the TPS25948 chip they're using for doing the parallel battery stuff is a cool find. it's an 8A efuse with all the typical trimmings like OVLO and UVLO, but the linear FET pair they use for inrush control and active current limiting also doubles up as an ideal diode OR so you can run them in parallel.

thread in which I talk about why the "wrap your games console in a towel" or "reflow the bga" thing works to fix some consoles, and it's nothing to do with solder balls.

@foone yeah, certainly seems like they put a ton of effort into it. any evidence that it might be a licensed library?

@foone heh, this sounds like .NET

PCMCIA is how spies encode their audio files

when my Glasgow showed up I immediately got nerdsniped by the hardware design, which had a lot of neat tricks. I started digging through the schematics, figuring out how it all worked, and ended up writing a pretty comprehensive description of how the hardware fits together and behaves. and now, with assistance and input from the Glasgow folks, that documentation is now part of the official docs :)

@endrift @foone plus makes me remember that Tim Allen exists, ew

@aburka @foone perfect reply, A+ no notes

@LunaFoxgirlVT why is it jet black

@foone I went digging through the modding stuff and it looks like there is a resource management mod, but nothing to make the rocketry more realistic.

did stumble across this though, which looks cool: https://outerwildsmods.com/mods/trajectoryprediction/

@foone ah, we're in full "ballistic trajectory goes brrrrt" territory then.
