This one comes from people participating in civil disobedience. It's oustanding. This is me vouching for it.

I'm building today. Not digital stuff. Physical. Moving Earth. Repairing some infrastructure, moving some of it, and building some as well. Preparing for the growing season.

No pics today, but moving several cubic yards of dirt and hard digging a hole big enough to bury a swimming pool. OK, so it's only a kiddie pool, but it's big enough to contain the extremely invasive things that send out runners like horseradish and mint.

When all said and done, it'll save us at least an hour **a day, every day** and allow us to have the outdoor herb garden we've been planning for years.

Got 7 of 8 built though, so that's progress.

On the last one, I found the short and fixed it. Now I can flash firmware onto it, but the button isn't connected. I must need just a little more solder under the CPU.

That's going to have to wait though because I ran out of time. Now I'm hanging out with friends, doing non-signet things.

Yep.

I have issues with not getting enough if the paste is even slightly dried out and it sticks in those tiny holes for pads of the CPU.

Other times I have too much due to something that I haven't quite nailed down yet. Maybe the board moves a tiny bit, or the way I'm peeling the mask off, or some little detail where I am being inconsistent.

0402s. The next hardware revision is going to standardize on 0603s instead of this mixing and matching.

0201s... nope. Not even once.

Of the 8 #signets that I just soldered together, 4 of them work.

This is a typical success rate.

I hope to have a better success rate in the next revision by putting all components on the same side of the board, and using smaller, higher quality, more expensive solder paste.

Now, I try to determine what is wrong with each device and take notes so troubleshooting and re-work is easier in the future.

It's #signet Saturday! It's hard to convey just how small some of these parts are that I'm soldering together.

There are 4 resistors lying on the cutting board in this picture.

The flickering screen on my #Linux #Surface continues to get worse. I'll keep using it (with an external monitor) for as long as possible, but at some point (possibly very soon) this will no longer be a mobile computer.

I double checked my #backup sitation on this machine and it was less than 12 hours old. I even looked for a specific text file that I created last I used the computer and confirmed it is in the backup, so I'm confident that's going well.

I'll probably try to get by with only my phone and not-so-mobile computers when this thing finally kicks the bucket.

If that doesn't go well, I can take it to a local repair shop to get the backlight replaced, although I'm not sure if that will fix the issue since moving the mouse makes it flicker less or sometimes stop flickering entirely.

Nailed it. Homegrown right here indoors.

Today's harvest. Do you recognize it?

Answer is in the image caption.

I imagined an open group being like a public pub. When the cop walks in, the topic of conversation changes and the officer doesn't know what was said before she arrived.

It's open to all, but there's no NSA-style collection so they can go back through time when they fimd a person of interest and find out all of the people they talked to.

That's why I would want to encrypt it. To enforce the "you had to be there" aspect of conversations that people are accustomed to with in-person conversations.

Creating a group on Session requires a server with a clearweb IP. It’s essentially just a website. Go to this link and you can literally read the conversation from our group chat:

https://session.simplifiedprivacy.is/r/simplified/

All Session is doing is for group chats is piping that website into your client.

On the other hand, the one-on-one chats go to a nodes. And so system we’re presenting here is completely separated from a physical location and the ability to take it down.

😳 I guess session groups chats are... completely unencrypted?! Yikes!

Today is the first I've heard of Session. I read the technical explanation of their protocol and walked away thinking everything was e2ee.

I saw references to onion routing, swarms, nodes, staking and some blockchain token thing.

https://simplifiedprivacy.com/uncensored/ also mentions something that sounds like decentralized DNS, which was helpful, but I don't understand how all of it fits together.

A network diagram and sequence diagrams for various use cases seems like the would be just perfect to explain the sysyem to people new to Session.

It's all good, but the chocolate covered coconut is the best. Its only competition is the cherry on top.
