I just got 9 yd³ of mulch that needs moved, and I already had 1 yd³ of compost that also needs moved. I'm going to sleep well tonight! Or possibly this afternoon. #gardening #plants #vegetables #homestead #homesteading

"Propaganda works best when those who are being manipulated are confident they are acting on their own free will." -- Joseph Goebbels "The rank and file are usually much more primitive than we imagine. Propaganda must therefore always be essentially simple and repetitive." --Joseph Goebbels Take a moment to think about what this would look like in modern times.

I try to see the positive things in the world. It takes effort in these times. Maybe this AI developed software will be a huge boost to open source projects. They will continue to be done by people who write software they use, not being done for profit. As a result, their real quality will not change, but their relative quality will improve as commercial software declines. Their privacy advantage might also become more important to people. Or maybe not. Time will tell. 🤷‍♂️

Ouch. $31 in shipping, jiat from DFRobot alone. But it has begun. I'm ordering parts so I can make more 🔥 #meshtastic #solar nodes I think with the bulk discounts I might be able to still hit the $200/ea mark. It depends on of there's going to be some hidden fees for the import tarrifs. Oh well. #yolo These 6db outdoor antennas aren't cheap. In fact they are more than the electronics (LoRa radio + MCU)!

Can someone who is an LND expert confirm I understand this correctly? I'm running a full bitcoin node and LND, as different UNIX users. The LND service has the keys for my bitcoin wallet. If my bitcoin node got compromised, the attacker woud NOT be able to immediately be able to drain any funds (because the bitcoin service account doesn't have access to move funds on chain, nor does it have the ability to read the macaroons needed to interact with the LND service). If the LND service get compromised, all funds are at risk. And obviously if the server gres rooted, the LND service is compromised. Did I get that all correct?

Fun fact, live A/V can not be cryptographically verified in real time. You have you batch up 5-10 seconds of data and sign that. If you try to sign each frame/packet, your CPU won't be able to sign fast enough. This is why e2ee videoconferences are symmetrically encrypted and all content is unsigned. You know it came from someone in the conference, but you can't prove from whom (cryptograohically speaking). Maybe with custom encryption hardware this could be done fast enough that humans wouldn't notice the lag of the pipeline: capture frame -> hash -> sign -> encrypt -> tx -> rx -> decrypt -> verify -> play It'd still be tricky to get the data around to each component fast enough. Having an FPGA with an integrated NIC that would accept raw audio and video frames and deal with hashing, signing, encryoting, packing them up and shoving them over to the switch all in one device would be pretty slick. In a world of quality deepfakes made easy, this could be just the ticket to restoring faith that something is genuine.

If you want a geek yo get in shape, buy them a couple meshtastic devices and a bicycle. Everything else will just fall place naturally.

Keyloop got all messed up on the first and second prints. Strung right over where the hole should have been. image Cleaned up the first two and printed a third with tiny supports that came out better: image

Got the #solar power monitoring working on the #meshtastic node on my bench! image Right now it's just connected to a wall wart, but it'll measure solar production once it is on a roof.

Oh no. It looks like WaterBrick moght be going out of business. 😭 Last week they were sold out of all food bricks and my order for replacement waterbrick gaskets failed to go though (with an error message about as useful as "order failed"). I emailed them about it. No response. I followed up. No response. Now their site is down.

Been busy lately. Not much time to kick back and chillax with #nostr. I don't expect it'll slow down for at least a month. Then there should be a nice little break before the gardening madness ramps up. Then it'll be washing, prepping, cooking, and preserving fod for months on end. Won't have time for #OpenSourve projects like #signet, social media or building #meshtastic #radio gear until winter sets in
