ought to be. With the appreciation for the help from everyone reporting issues
to us, we’re happy to now release our best version yet - 0.12.1 is here!

Notably, we made a couple of changes that improve compatibility with Jitsi

We don’t have meaningful social connections anymore like our parents or their parents geeration had. We are so scattered, that I am unsure how many of my friends are actually friends and how many are just professional contacts. Everytime I switch job, almost 70% of my friends suddenly fall out of contact. Heck, I don’t even know the people who live in next apartments both left, right, up and down on the same building. Socializing with my friends mean, setting up an appointment weeks ahead to see if we can align on a free-slot and this often involves all of us commuting to somewhere and disbanding by 22:00 hours because family, work next morning, chores to do, doctor appointment and other human things.

Spent the last few days debugging network issues at work.

Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.

A very time consuming process. Even more so if you try not to cause downtimes for your users.

I want a magical device that allows me to look inside a cable/fibre.

But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

In-reply-to » @prologic Re: Chat system, What if the base specification included a system for per-user arbitrary JSON storage on the server? Kind of like XEP-0049, but expanded upon. Two kinds of objects: public and private. Public objects can be queried by anyone, private objects cannot and must be encrypted with the user's private key. Public keys could be stored there, as well as anything else defined by extensions. Roster, user block list, avatar, etc.

For instance I normally use the same RSA key/pair on all my workstations for my ssh client, because that’s me, no-matter where I am. The only exception to this rule is I usually create a separate key for any “work” / “ company” I am a part of.

JMP: Why Bidirectional Gateways Matter
A big part of the vision of Sopranica, and Cheogram in particular, is bidirectional gateways.  A bidirectional gateway is one that allows (at a minimum) any user of either protocol to contact any user of the other protocol without creating an account.  This is not possible with all protocols, but works well when both sides are federated.

Simple Example

Take for instance sip.cheogram.com, which is a bidirectional gateway between XMPP and SIP.  Any … ⌘ Read more
