I am proud to announce that the SDR #Falcon9 live decoder is almost done!!! Managed to get it down to 15% CPU total! This module makes decoding the falcon9 as easy just clicking a button. I hopefully will release it tomorrow, so stay tuned! #SDR #SDRPP

I just made the world's worst reflow oven out of a $25 walmart toaster oven, a solid state relay, a thermocouple and a raspberry pi pico. Total BOM is $60. (1/4)

As for the reflow results, I didn't have solder paste on hand so I had to cut out solder wire by hand and add flux. Clearly put too much on there and wasn't precise enough which caused one of the parts to tombstone. (3/4)

All in all, even with better tuning, I wouldn't be comfortable putting any expensive board through it. I think the next step is insulating it better and finding a way to reduce the thermal delay from element turning on to temperature rise (4/4)

The supply chain attack on the #ArchLinux #AUR was inevitable. 3 years ago, the AUR admins gave away control of the SDR package (that I was maintaining) because someone complained about a minor versioning issue that I didn't want to fix. (1/4)

The AUR admins preffered giving control of the package away from the ACTUAL DEVELOPER to some random person complaining. Mind you, I was dealing with my mother dying of cancer at that time, a minor versioning issue was the least of my concern... (3/4)

In my opinion, ArchLinux needs to purge the entire AUR admin team and replace them with more competent people. They should also use common fucking sense and not transfer ownership of a package if said package is owned by the developer of that software...

#Debian are trying to package SDR and butchering it πŸ€¦β€β™‚οΈ. They left out a ton of modules and changed the way the core library is installed and loaded in a way that prevents you from installing any of the modules they removed... (1/4) packages.debian.org/sid/sdrp…

I don't want to deal with thousands of users: 1) Running outrageously out of date versions 2) Complaining they don't have the modules SDR advertises 3) Not be able to install those missing modules....... Imagine the support load!!! (3/4)

Does anyone know if there is any way for developers to request their software NOT be packaged by the distro maintainers? I've been maintaining official SDR debian packages since day 1, I don't need them to come and create chaos.

Oh well, was fun discussing the spacex stuff with everyone but I've got shit to do instead of yapping on twitterπŸ˜†

Has anyone received the email yet? I put in my reservation the minute that the page went live back on may 8th and still haven't received the email to let me order it. I left my old controller back in europe, haven't been able to play controller based games in almost a year😭
Steam Controller update: Reservations will be available on @Steam beginning tomorrow. Details here: store.steampowered.com/news/…

As someone who studied spacecraft design, this is the single dumbest thing I've ever read on here. Thread (1/x)
Okay this is genuinely insane. SpaceX just unveiled a satellite whose only job is to run AI. Not internet. Not GPS. Just compute, floating in orbit. It's called AI1, and the reason behind it breaks your brain. AI data centers on Earth are hitting a wall, not a chip wall, a physics wall. They need staggering amounts of power and water just to stay cool, and we're running out of grid and land to build them. So Musk's answer is: stop building them on Earth. In orbit, the sun never sets. Free power, 24/7. No water for cooling, you just radiate heat into the vacuum of space. The two things choking AI on the ground barely exist up there. And here's the wild part: Musk says it's easier to build than a Starlink satellite. Strip out the complex antennas and it's "a lot of solar cells, a radiator, and some laser links." One AI1 carries the compute of an Nvidia GB300 rack, the same hardware data centers fight over down here. AI1 is just the first one. The plan is a constellation of up to a million of them. And the timing isn't an accident, SpaceX goes public this week at a ~$1.75 trillion target. This isn't a rocket company anymore. It's positioning itself as the power grid for AI, in space. The race for AI compute just left the planet. Literally. @SpaceX

3) Solar panels are the least efficient way to generate power, and they quickly degrade, especially in LEO through ionizing radiation and micrometeorite impacts. You can see again just how huge the arrays they need are, and they will only last a few years.

Why are we letting these morons ruin LEO with even more *LITERAL* e-waste? This is again one of musk's moronic physics violating ideas like the hyperloop (remember it?) that won't go anywhere but he'll still somehow make billions from it at the cost of everyone else.

SDR was created on this day 6 years ago because I thought I'd teach myself DSP while my highschool closed during covid. Never thought it would get this far... I wouldn't be doing a PhD right now if it wasn't for this software and everyone who's supported me!
