I'm almost done the section on Megolm encryption/decryption in my Matrix client-writing tutorial. Most of the structure is there. I need to fill in a few more details, and write some more tests. Next up will be Olm encryption/decryption. -

I should also add: feedback is welcome. Let me know if I've missed anything, or if something is unclear, or if my Python code is terrible. -

I haven't mentioned it here yet, I've been (slowly) writing a tutorial for writing a Matrix client. It's still in the very early stages, but I've gotten to showing how to send and receive events, and I've recently been working on the end-to-end encryption section. For those who saw an earlier version, you can now know more than you wanted to know about uploading device and one-time keys, and keeping track of recipient devices.
The tutorial is available at uhoreg.gitlab.io/matrix-tutori…

I have to laugh and shake my head at Smith calling it a "Miracle on the Praries". No, you were leading in the polls pretty much the whole time. You're in a strongly conservative province. I mean, if you're saying that it's a miracle that the majority of Albertans chose to ignore your terribleness, then yes, sure. But people voting the same way the polls said they would isn't a miracle. If the UCP ran with a saner leader, they probably would have won by a lot more. -

Alberta, I'm disappointed in you. Especially you, Calgary. Though, congratulations to the seats in Calgary that managed to flip. And Banff-Kananaskis. Lethbridge-West, why couldn't you be more like Lethbridge-East? -

Alberta, vote today! How is it that the UCP is polling ahead of the NDP? I know that Alberta likes their conservative governments, but with the things that Smith has said and done, the UCP shouldn't be polling so high. Get out and vote. It doesn't matter if you're in a "safe Blue", or a "safe Orange" riding. Vote! -

Ugh. Why did they move the "Start" menu away from the corner? And there seems to be no way to move it back. -

It's taking over 4 hours to download a VM image of Windows with Visual Studio that will expire and be unusable in 3 months (and I'm lucky that such a VM is even available, though I won't be surprised if, after it's done downloading and I've set it up, I find out it isn't what I need). It took about half an hour to download a VM image of FreeBSD that will never expire. I hate working with proprietary software. -

A Spanish climber has spend 500 days in a cave: www.cbc.ca/news/world/spain-ca…
"Asked if she ever thought about pressing her panic button or leaving the cave, she replied: 'Never. In fact I didn't want to come out.'" Ah, I see that she's been keeping up with the news while she was in there. Can I go live in a cave too? -

The other day, on the radio, they were talking about the power outages in Quebec and Eastern Ontario. The commentator was saying that in Quebec, most houses are heated with electric heat since they have pretty cheap electricity there, so if the power goes out, they lose their heat and they'll get cold. And I was thinking, "Sure, but the gas furnaces that we have here still need electricity to run, so if we lose electricity, we'll get cold too." Somebody obviously hasn't been watching enough @Technology Connections videos. -

Yes, I agree. I would have liked to be able to use an unaltered MLS for Matrix, but haven't figured out a way to do it. Of course, just because I can't figure it out, doesn't mean it isn't possible, and if anyone has any brilliant ideas, I'd be happy to hear them. -

I don't think I ever said that the servers need to have any knowledge of the group membership. All I said was that "the application has a way to allow clients to determine the membership of the group in the face of concurrent changes to the group membership." Whether it's done client-side or server-side, it shouldn't matter. -

If you're using a system where you can just use MLS's notion of membership, then you can just use that and ignore that part of my proposal. But if you're in a decentralised situation where membership changes can come from anywhere and need to be merged together, then you may need something outside of MLS to manage that. (Consider: Alice bans Bob from the room in one branch, and Bob invites Carol in another branch. When the branches get merged, should Carol be in the room or not?) MLS doesn't include any way of resolving those types of conflicts.
Also, MLS isn't a complete membership system; for example, it doesn't define any permissions, and deliberately leaves that up to the application. For example, if Alice sends a commit that removes Bob from the tree, is that a valid operation? MLS leaves it up to the application to decide if that should be accepted. -

The proposal is intended to be fairly generic. You need some sort of notion of who's in the group, or else you don't know who to encrypt for. -

I don't know about the timelines, but there's already talk amongst people in the MLS WG about working on a new version of MLS.
I don't think it's possible to use an unmodified MLS in a decentralised case. Even if you could create a strict ordering, would have to end up completely discarding some updates, which is less than ideal. -

Yes, good question. That's why I'm saying that I'm integrating a "variant of it" with Matrix. I've made some modifications (brief notes at gitlab.matrix.org/matrix-org/m…) to make it work in a decentralised system. There is more than one group working on approaches to decentralising MLS, and hopefully the next version of MLS will support a decentralised mode. -

Messaging Layer Security (MLS) has been accepted by the IETF for publication as a standard. MLS is and #EndToEndEncryption method designed for group messaging. I've been working on integrating a variant of it with @Matrix.org (keep an eye out for demos coming soon). I've sat in on some of the IETF meetings, and the (not yet published) RFC may even contain some words that I've strung together. Congratulations to everyone who worked on it!

As a result of working on some other personal project, I've ended up writing a literate programming extension for Sphinx: uhoreg.gitlab.io/literate-sphi… One problem with personal projects is that if you're not careful, they may spawn other projects. -

Twitter's new policy doesn't just affect people who want to link to their own profiles on other platforms. It affects people who want to link to other people. Want to promote your friend who only has a presence on one of the "prohibited" platforms? Too bad. Can't do that. -

Hooray! We're getting the beginnings of universal dental care in Canada. Currently only for children 12 and under, and only up to a certain income level, and there's a dollar limit per child per year, but it's a start. www.cbc.ca/news/politics/feder…
