OK. Somewhat successful day in setting up my #MeshCore nodes. I'd say it's all about 90% there. The next steps are to work out:

1) Why my short-range companion node (with the small, flappy antenna I'd swapped over from the Xiao) cannot be seen by the other companion node (to the right) or the repeater, and
2) Why my room server/repeater (the Xiao board on the left) *is* noticed by my other companion (on the far right) when I send a test message, but isn't picked up as a contact or a room server in the channels list.

Still, the solar panels work and it seems my return to soldering for the first time since I was 13 didn't break anything!

In hindsight, I've no idea why I didn't just buy 3 of the same device. It would have been so much easier. If I need to buy a new antenna, if that's the issue in point (1), then I will.

Seeed Studio Xiao nRF52840 & Wio-SX1262, currently boxless, but set up to be a portable, solar repeater and room server. It has the long antenna taken from the second Wio tracker, plus a battery and TP4056 battery charger I've soldered to it.

@druid Uncle Bryn's house on Barry Island is for sale, too.

@vongomben Perfect if you have a 3D printer.

@vongomben A portable repeater, ideally. I have no case for it and didn't consider the antenna's strength when I bought it. 🙄

My little Xiao board has arrived, and I'm planning to set it up as a #MeshCore repeater. I'm guessing I would need a more powerful antenna than the one it came with though, yes?

A surge in new datacenters, each with the power demand of 100,000 households and a cooling water demand of 1,000,000 m³ per year to train AI models on material obtained without consent on hardware now unaffordable to consumers so fascism-adjacent tech billionaires can sell us the idea that any skill is now worthless and in doing so creating the largest economic bubble ever while simultaneously destroying society and environment.

I think that about sums it up.

TIL that SSDs can lose data if left unplugged for long periods of time (only required to hold data up to 1 year), unlike HDDs which as long as the material holds it can take years.

Edit: added link: slashgear.com/1893447/dont-lea

Unlike HDDs that can sit idle for years and still spin back to life, SSDs slowly degrade when left powered off for too long. SSDs use floating-gate transistors to trap electrical charges. Those charges represent your files. But over time, even without use, the electrons stored in these cells can leak. That slow leak is enough to corrupt your data.

According to JEDEC standards, consumer-grade SSDs are only required to retain data for one year when stored at 87 degrees Fahrenheit. Higher temperatures accelerate charge leakage. This means that if your SSD sits in a warm room, you're basically cooking your files. Enterprise-grade SSDs have a shorter span of three months after unplugging. This phenomenon isn't new, but it's often misunderstood. Many assume solid-state means stable forever, but in reality, SSDs are more like batteries than safes. They lose their charge even when unused.

It took a while but it's shaping up nicely :) Post-Quantum Cryptography and Reliable Deletion, better known as Forward Secrecy, are going to become available in 2026 in #deltachat. For more details, including the recent #fosdem26 talk recording:

autocrypt2.org

@billzismyname Delete Sniffies. There's your answer. :)

@motoridersd Session is a messaging app that seems to be a cross between onion-routing technology, and the technology blockchain is based on (but it's separate from cryptocurrencies).

@voyagermesh OK. It sounds fairly similar to general advice I have seen in computing contexts: AES-256 is good, but the strength of encryption, when applied, largely depends on the strength of the password you set. #Meshcore offers no perfect forward secrecy. Change keys to chats as often as is reasonable, and if need be, share them securely and ideally out-of-band.
I saw on a linked website that Meshcore offers E2EE with plugins -- what are Meshcore plugins? I've not encountered any yet.
@djh

@djh And is that regardless of whether it's a private channel, private chat or room server?

@motoridersd "Consent-aware". Oh, the irony.

I know that private channels on #Meshcore are encrypted, but are room servers?

It seems the buzzer can be turned off when it's flashed with #Meshtastic but not #Meshcore...?

Edit: Version 1.11.0.2 and later of this firmware allows you to turn it off -- seems like it's undergoing rapid development!

Well, my two Wio Tracker L1 Pro devices arrived today (bought direct from SeeedStudio and no import charges had to be paid).
The plan is to attach a small solar panel to each by taking the plugs off of these two pairs of wires (pictured) and adding them to the wires on the solar panels (not pictured).
All good in theory... except these plugs are too small. 😣

I've since learned that the apparent size of the plug as described on, say, eBay is actually the distance between the two metal pins, not the size of the plug itself (the plastic housing).

Ah well. At least I can flash them today and check they work OK.

The solar panel socket is the small grey box on the left. It has the word "SOLAR" printed above it in small capital letters.Two JST cables with plugs on. These are both 1.25 millimetres and I needed them to be 2 millimetres.
D'oh.

Hello #meshcore users. Could someone explain please how powering a Meshcore node should work? I understand you can use solar panels and batteries to sustain a node self-sufficiently, but how do you recommend they be powered if not like that?
The videos I've seen have them connected USB-C to USB-A to a computer via an ordinary, slow charging cable that is capable of transferring data. Would connecting this to the mains via an adaptor plug also be a good idea, or too highly powered?
Is it essential to have a constant power supply, or does it depend on the device?
