RIP 🪦 BitRefill's pre-paid MasterCards. #BitRefill no longer has any digital credit cards that can be used to pay in person. The only option is to have a physical card mailed to you, which is better than nothing, but far inferior to what they used to have.

@Daniel Batten Have you seen the paper in Nature that quantified the PM2.5 pollution attributable to Bitcoin mining in the U.S.? Any comments? One thing that stuck out was "Fossil fuel power plants generated 85% of the increased electricity demand from Bitcoin mines, including 138 coal-fired and 497 natural gas-fired plants." https://www.nature.com/articles/s41467-025-58287-3#auth-Gianluca-Guidi-Aff1-Aff2-Aff3

Remember back when people used passwords? Yeah that was tedious!

Reminder: The Dead Milkmen I will not be taking any questions at this time.

In 2022, the Federal Reserve Bank of St Louis started tracking the cost of eggs in bitcoin and USD. At the time, it showed 18 months of data and illustrated that bitcoin is much more volatile than the USD. Now we have 4 years worth of data. USD: 1.466 ➡️ 5.897 (+302%) sats: 4217 ➡️ 6223(+48%) In just 4 years, using only data from the federal reserve, we see that: 1.) the value of eggs is volatile, and 2.) #bitcoin has lost far less value than the #USD, at least measured in eggs And even though it has a URL in it, you should never take a screenshot like this at face value! Check to make sure I'm not pulling a hoax on you. I'll even save you from having to type in the URL.

#ProofOfWork. Mixing in rice hulls. Probably have about 4 more houts of work left 'til it's done. #gardening #permies #permiculture #homestead #homesteading #garden

This project is hardcore! #OpenSource, #hardware, #firmware and #software. You can buy pre-flashed hardware. The catch? It's not clear what components to buy or why, and the setup process is so difficult, it's effectively your new hobby. I expect it'll get better as out gets more popular and more people contribute to the documentation. #electronics #diy #OpenHardware #FOSS

GM. Time to set aside the cross #compiler for a while and switch to #house and #garden projects. I should be working on mixing rice hulls into the soil of our raised garden beds, but I worked on the open source energy monitoring project. Made progress, but it's not tracking our usage yet. Tomorrow I hope I can get some rice hulls in between working for the #Artisans #cooperative, meeting with my local elected representative, and helping cook meals for this week. Because it's calling for rain the day after tomorrow.

I managed to get botan (the cryptography toolkit) cross compiled for Win x86-64 (from Linux x86-64). It took all day, but I got it, including even running the test suite under wine to verify it's all correct. Patch submitted to libbotan to make it easier for others in the future. Now I'm trying to figure out why the cmake files in keepassxc aren't able to find my newly created botan-2.pc file that defines how to link to the library, what library and header paths should be included

Today I got botan2 cross compiling for x86-64 Windows (from Linux x86-64). Why? Because I want to cross compile keepassxc and this is getting in my way. Why do I want to cross compile keepassxc? Because I want to use that code in the signet client to import keepass v4 databases And I want my (Linux based) CI to be able to continue to crank out windows builds. That's why. After Botan, I'm going after argon2, and then others. Oh and I had to build my own compiler because mxe repos are way old. So I'll probably be hitting up their mailing list to find out if someone has the ./debian directory that produced that .deb file so I can give them an updated build. If nothing else, I'd like to at least built it and put it in my own apt repo. Yeah, I'm way down the rabbit hole on this one. And if I manage to dig myself out, I'm going to do it all over again for i686!

I am having so much fun with disposable VMs (DVM) in #Qubes, it should be illegal! I'm doing #dev work again today and when I think I have the minimal commands to reproduce an issue, I'll spin up a DVM, paste the commands and make sure I hit the problem I expected. If not, I'll poke around to fix it (install a dependency, update the PATH, etc.) and then repeat. Takes about 8 second to spin up a fresh VM. Very rapid #development!

OK, normally when I hear about someone who doesn't know crytpography or Rust writing Rust code and rolling their own cryptographic protocol, I'd almost certainly not going to use their code... but... Wang Lu seems to be the real deal, just picking up these skills along the way. Their highly experimental hardware password manager, which is not open source hardware nor software, sounds like it's a pretty decent design. If it actually does what is described, I am impressed. It'll be interesting to follow along and see if it turns out to be an even more hardcore password manager than the #Signet. Of course, there's no proof that any of this code exists and works, so it could all be vaporware. We won't know unless it's released (in either source of binary form).

Productive day today! #gardening - I mixed about a cubic yard of soil & rice hulls, put the rain barrel back in service, and took a first pass at fixingthe gutter #signet - documented using the qt creator IDE, fixed all compiler warnings, and improved the Windows CI/CD build pipeline

Not much going on today. No #meshtastic #solar node updates because I'm waiting on the lower gain antennas No #Signet cross compiling updates because I'm busy doing house projects to get ready for gardening. No #gardening updates because the tasks are uninteresting, like level the rain barrel stand and fix the gutter. No production server updates because a.) I was waiting on RAM, and b.) it's boring. No test server updates because I've been procrastinating fixing it ever since it literally blew up on me last time I tried to turn it on. But in truth, all this completely unsexy grunt work is what enables the interesting work. So I soldier on. Getting stuff done. Like a boss.

Cross compiling is usually difficult to get set up, but that's doubly true when the target is macOS, square that if it's QT and square it again is it's a different CPU architecture. I'm trying to grind through it, but I think it might be grinding through me instead. I'm attempting to start with the same CPU architecture (x86_64) to minimize the number of concurrent changes. One of us will be more stubborn, and I think I'll eventually outlast the build tool, as good of a fight as they may put up. #development #mac #linux #foss
