Done! I built a functional Meshtastic node for $5.24:
RP2040-Zero - $1.74
RFM95 - $3.50
I omitted a screen, as that would have brought the price to $7.44. it works great over serial!

Signal FOSS is a fork that takes out the closed source bits. More info here:
https://www.twinhelix.com/apps/signal-foss/
It still connects to Signal's centralized server and doesn't provide an option to connect to any other server. And that server requires you provide your phone number, but it's at least slightly better than thr stock version.
There are at least two other forks, but I can't remember what they are off the top of my head. None of them get away from phone numbers or centralization.

I've been struggling to focus on Signet on Saturdays ever since I started #Signet #Saturday. Making real progress on this project requires complete focus, and that's hard enough for any day, but especially hard on the weekends.
Plus Saturday night is the day I make myself available to hang out with friends who don't live near me anymore. I started that in mid-2019 and it's damn near the only way I stay in touch with people. Since I'm not ready to give that up, it means if I get started on Signet and get deep into the weeds, I'll be interrupted. And I've tried working on Signet while chatting with friends and I end up losing focus and progress is slow to non-existant.
As I'm writing all this out, it seems like I'm coming to the conclusion that Signet Saturdays will have to stop, despite the alluring alliteration.
I'm not sure if I'll try to dedicate another day of the week to it or not. I think it's more likely that I'll work on it non-stop for several days in a row, abandoning all other responsibilities. This seems to be the way I work best, for better or worse.
Anyway, thanks for listening to my ramblings into the void. If you got this far and have any constructive advice for me, hit me.

I was interested in the Sideband Android app until I discovered that they closed ths ticket asking to be added to the #Fdroid repos, claiming it's too much work and not enough benefit. 😭
F-Droid reviews all apps in their default store to ensure they are really #OpenSource (or #FOSS or #FLOSS if you will) and looks for trackers. They also require a description of what changed from one version to another.
These are benefits that you don't get by installing an APK directly from Microsoft GitHub.
It's completely valid to say that benefit isn't worth the effort. That's a value judgement. To some, even a trivial amount of effort is too much. To me, it's a significant value, and if it were my project, I'd create a .yml file and submit a MR to FDroidData.
Now, the effort to make their build reproducable is a different question. That may be easy or it may take a significant effort. Whether reproducable builds are worth the effort or not depends on how much the project cares about #security. How much work it is depends on whether and other projects using buildozer have already done this. If not, it'll also depend on whether the builddozer devs are interested in helping their users do this.

Well, Reticulum is built on top of Meshtastic, which is built on top of LoRa. So Reticulum won't solve any range issues.
I know it can use 801.11 and Ethernet, but thise are way shorter range than LoRa.
Reticulm is cool, and it does have its place, but it's not very interesting without Meshtastic. It is Meshtastic that is the critical component for getting long range comms without the internet.

I want Meshtastic to do e2ee DMs from my phone to the recipient's phone, not from my node to the recipient's node. There is a big difference.

#Heltec v3 #meshtastic users, where you at? I'm trying to figure out why the amber light keeps coming on with one of my two units. I am having some message delivery problems, but I am not sure if they are related.
It's plugged in via USB-C and there's no battery connected to the back, so it's certainly not charging a battery, despite what some reddit users report the amber light meaning.
My other unit has a blinking white LED and it is being powered by a lithium-ion rechargable battery (NOT via USB-C). This one is working as expected.

No. I can't really tell if they have anything novel there. It looks like it's just a common standard for killer robots. Could be basic OOK or FSK under the hood. If you have something compatible, you could probably figure it out pretty quickly with an SDR. Or GNU radio if they use spread spectrum frequency hopping (like BT).
At any rate, I'm not interested in interfacing with anything that uses WaveRelay.

I checked with client.meshtastic.org and confirmed the radio was set up right, and the channel showed up there. Then I got distracted and when I came back to the Android app, my channel was there.

Looks like @nprofile…nqve has already given a better answer than I could on the cognitive dissonance aspect.
As for strategy, I'll just add that:
1. I'm not sure I have any better ideas than anyone else on the topic
2. But I have spent some time thinking about this and have some ideas on some different paths forward
A. Governments basically force people to accept bitcoin. I don't like this one, but it is an obvious one.
B. Culture shift, which is the main focus right now. Make it normal to split the check with bitcoin. This can be done now with lightning and having the person collecting the money pay the establishment in cash/credit. Advertise that you accept bitcoin when you sell stuff (where possible, places like eBay don't like this 😂). Other things that would fall onto this category in my mind would be to have bitcoin featured in movies as just a normal thing. Not part of the plot. Not character development. Just casual usage.
C. Negotiation. Maybe this is the wrong heading, but the idea is to only accept bitcoin and not fiat. This only works well if you've got something highly desirable to offer. It also means you will miss out on opportunities. For example, when looking for an employer, show them how much of a perfect fit you are and then walk away if they won't pay you in bitcoin. Or if you make amazing art or jewelry or whatever that people can't get anywhere else, people will either get some bitcoin via PayPal or whatever and pay you, or they won't get it.
I like this option, but it kinda depends on option B to get enough producers to participate that it will have any meaningful effect. Missing out on a single product because you don't use bitcoin is one thing. Missing out repeatedly is another.
If people have a choice to pay in BTC or fiat, they're likely to use whatever is familiar and convienent. This means not many people switching. If the terms of the deal are "bitcoin or you can't have this cool thing" they have to decide if it's worth the time & effort to get some coin. And that's a big hurdle. Getting it and using it once.
I guess a middle ground would be to offer discounts for paying in bitcoin, which is becoming more popular and something I do personally.
As YAR noted, there are more or less public ways to advocate for bitcoin adoption. You can talk to the masses, or friends and family, or somewhere in between.
However, I strongly feel that the first step for any advocate is to eat your own dog food. If you think people should use and accept bitcoin, then you should accept it. You should be familiar with a set of tools and/or services that work well so you can give people a slick demo if they are interested.
Anyway, that's just my two sats. Obviously I haven't succeeded in getting mainstream adoption yet, so maybe I'm just that crazy uncle. 😛

I don't have an direct on second level contacts with any insider knowledge on Proton or IVPN, so all I know about them is what's public info.
Think about what info you are trying to protect from whom. If you want to prevent your ISP from knowing what sites you visit, and the sites to not know your IP address, a self-hosted VPN works great.
Also defending against the cloud provider hosting your VPN, or a global network observer is far more difficult. Best bet there would be to connect to a VPN over Tor. Here are the tradeoffs:
+ ISP can't see where you're going
+ VPN doesn't know your home IP address
+ websites don't see your home IP
+ you can use websites which block Tor as long as they do not also block VPNs
- VPN may slow down your connections
- Tor may slow down your connections
? VPN may know your name & address depending on how you pay
? VPN may require you to give them a working email address, but usually not a phone number

Sounds like you already understand the tradeoff between trusting your ISP vs trusting a VPN provider. I'd say Tor is better, but sometimes you can't use Tor for one reason or another.
I'd suggest RiseUp when you want a VPN. You don't even need to give them an email address. Pay what you think the service is worth. Homor policy.
I know people who personally know and vouch for the crew that run it (and the other RiseUp services).

You may have heard of the "slippery slope"
First, you discover #nostr, then #LoRa and #Meshtastic, then things built on top of these like #reticulum and #nomadnet
After that, you decide to stick it to the closed source software. You purge Windows and macOS, switch to #GrapheneOS and #Linux.
Then you start purging the simple closed source #hardware starting with all those IoT devices. #Nest ain't hoovering up your data anymore. You tell #Ring to GFY. #OpenSource everything.
Next thing you know, you're driving around with your #phone in airplane mode. Good luck tracking your every move now, overlords.
Then you're biking & walking with your phone in airplane mode instead of driving. High gas prices, drivers licenses, car insurance, #ALPR systems... they ain't gonna stop you.
Then you start your own #garden and learning how to preserve food. 50% inflation on food? Not a huge deal. You got this.
Later your leaving all #electronics at home and paying for everything in cash. You know the routes that minimize exposure to security cameras. You're nearly a ghost.
I'm not sure what comes after that, but I'll let you know when I get there.
These may happen in a slightly different order. Each person has their own path. But once you start going down the "STOP FUCKING EXPLOITING ME" path, and stop paying the people who are doing it, it's extremely hard to stop. It feels so good to be free from all that nonsense. You want to keep going and never look back. #cypherpunk
Take the plunge. Start with just some small things. You won't regret it. And if I'm wrong, you can always turn back anytime.

I like the idea, but there are serious problems with leaking metadata with #nostr DMs. Not sure people care, but having the ciphertext available to everyone is a risk.
It can be mitigated by having a unique relay for each group, but requiring people to do advanced relay management is not a recipe for success.
This could be fixed at the protocol level. E.g.
Client: give me the encrypted notes for key ID 0xabc123
Server: Sign this nonce with that key and they're yours
Client: here's the sig
Server: here's the encrypted DMs
It still lets the relay see who is messaging whom, when and how often, but that is very much like Signal. But unlike Signal, nostr could pick a different subset of relays for each message so no single relay has all the information. As long as everyone in the group is using the same set of relays, that should be reliable.

OK, I'll admit that this is better than I realized, but I still don't see any files that would allow anyone to get a PCB made.
Nor do I see the original source files which would allow anyone to modify the PCB design and contribute back to the project.
Until I see this, I stand by my statement: BitBox is not open source hardware.

There are more than a dozen consolidation transactions in the mempool that are willing to pay almost 4M sats (~$2500 USD) in fees right now. That's at 40 sats/vB. Clearly someone is expecting the on-chain fees to go up from here!

This was probably about a gallon of peppers when they came in from the garden and we got maybe $5 worth of pepper flakes.

Yeah, I've heard that too, but I've done bandwidth testing on that network and it has about 900-950Mb of bandwidth to spare.
I'm not trying to get 1Tb/second or anything crazy like that. I'm just frustrated at getting less than 1MB/second.

I did it for the live migration capabilities. Probably overbuilt, but live and learn. It wasn't fast enough without the SSD DB devices. But then again, I feel that it's still ot fast enough, so 🤷

4 hosts, 21 OSDs, a bit over 100TB total raw capacity.
OSDs are a mix of big expensive SSDs and "HDDs with an SSD as a DB device" (and thus it also serves as a WAL device). There are no HDDs without an SSD in front of them.
Workload is about 40 VMs which vary greatly in disk activity. DNS, basic web services are super lightweight, but heavier hitters like the InfluxDB server, GitLab, and Mastodon.

2024-10-06 20:26:38 GMT

4 of the first 25 papers on https://arxiv.org/list/cs.CR/recent are about DNS right now.
It's interesting to see such an old, critical technology to get so much attention. Usually academics are trying to chase the buzzword of the day.
To be fair, one of them does have "Large Language Models" in the title, so there's still some of that "write about what's popular, not what's important" thing going on too.

2024-10-06 19:56:25 GMT

Yesterday was a rough day for me as a #sysadmin, but #ceph still maintained its perfect record of no data loss, even though I don't 💯 understand all the inner workings.
At this point, I'd say it is battle tested. I've had concurrent drive failures, and this latest issue where it couldn't find the DB device fors of 17 of the 21 drives!
I'm not sure I'd go with ceph again if I had to start over. It allows live migrating running VMs to anither host, which is a huge win for avoiding downtime and saving disk writes for migrating an entire hard drive (as opposed to just migrating the confents of memory). But having standalone disks would be way more performent in terms of both I/O and memory usage.
If I could get equal disk I/O performance, I'd choose ceph for any #SelfHosting. Maybe not for a #homelab, where nobody relies on any of the services, but certainly if you're using it in your daily life.
I still have a #bounty out of 300K sats for anyone who can get me 100MB/s random read inside a VM and 100 IOPS for the rados write benchmark.
What I actually want is for VMs to run at least as well as if they were on a standalone consumer grade hard drive, but I'm trying to provide concrete metrics so there's an objective metric of whether it goes "fast enough".

I went through the free LoRa/LoRaWAN training from Semtech a couple years ago and it was very good at explaining how it works to non-experts.
https://learn.semtech.com/
IIRC, you might have to look up videos on thinks like OOK or preambles to understand those parts, but that's easy once you know what to look for and have the context of how it is used.

2024-10-06 15:17:20 GMT

Dear people who want to #decentralize everythingband are a fan of #LoRa, #meshtastic and #OpenSource,
I'm writing to you today to inquire where you stand on the fact that it's all based on a propritary radio, created by a single company. If they were to discontinue this line, it'd mean no new hardware.
It may sound unlikely to discontinue a product that people love, but this recently happened with GoTenna. You can still use existing hardware, but no new gear, no support, no growing your network, no bringing other people in.
Has anyone successfully used an SDR to interface with LoRa? That would eliminate the single point of failure.
This also applies to things like #reticulum and #NomadNet which also rely on LoRa.
