Yeah I didn't hear about it at all. Too bad it seems it was only for high schoolers.

Thanks for sharing! I had look on meetup a couple months ago to just find events in Ottawa and never saw the nerds and nachos event. I joined the meetup to get notified of future events. Doesn't look like anything is scheduled right now. Do they use anything else to organize though? I'd prefer to avoid meetup if I can. I don't like how they force organizer to pay for an account.

Some of the developer people from OCLUG have a social event as well on the second Tuesday of every month. I've been attending that, but I'm very interested in having something more project focused in the city.

I saw you signed the sheet as well, thank you!

I'll preface saying I'm not a security expert but my understanding Is sometime in 2025 they changed the encryption scheme in matrix following a lot of disclosures of how it was broken to a new scheme that uses MLS and supports forward secrery. I haven't seen a post yet from security experts discrediting it yet. It sounds like it still has issues from what you're saying, about soatok disclosing some new problems with it.

On the call side they have element call instead of relying on a jisti widget (but only a few client support it). Afaik it supports encryption. They talked about it last year at the matrix conference https://cfp.2025.matrix.org/matrix-conf-2025/talk/BQZHAH/

You're right, I was wrong about signal using MLS. I recall reading it somewhere but can't find the source now.

As for my response, it was about forward secrecy which they do claim to have now. Yeah I wouldn't rely on matrix E2EE right now, and until its been seriously audited and replaced with something security experts agree on.

For a discord replacement (with public not E2EE rooms) it seems to be the best replacement just because that's where communities are right now. XMPP+OMEMO is not that interesting to me because I don't know of any communities that are on there or other users to be a Discord replacement and its E2EE story is not as good as Signal to be a Signal replacement.

For a signal replacement I'm not sure SimpleX or Briar are there yet. SimpleX doesn't have multi device support last time I checked which is annoying if you're used to useing signal on your phone + desktop. Any Briar doesn't work on IOS, so if you chat with anyone who has an iphone they are SOL.

 

So I’ve been following some FOSS/linux software groups around the world like GPUL in Galicia and Chaos Computer Club & Modal Collective in Germany and I’m a little jealous of what they’ve been able to build in their associated cities/regions. For example GPUL is organizing GUADEC (The GNOME community’s annual conference) this year in A Coruña, and they regularly run workshops to get people into FOSS software development at their local university UDC. They’ve also organized (or helped organize) previous events like XDC (The X.Org developers conference for wayland/x11/mesa and related technologies).

Likewise the Chaos Computer Club (CCC) promotes open source software and runs similar events including the annual Chaos Communication Conference. What they put together seems like a great "CS Club" but outside of a university and open to the public. The Modal Collective in Berlin hosts a regular (every 3-4 months) un-conference + hackathon event (called Boiling the Ocean) working on a few different open source projects like GNOME, Postmarket OS & p2panda.

I'd love for something similar to exist in Ottawa. I've followed some groups here like OCLUG (Ottawa-Canada Linux user group), and Ottawa Systems (https://ottawasystems.xyz/) and they meet some similar goals but not exactly what I'm thinking. (I have some notes below on those events)

To me it would be awesome if we could have something like the Boiling the Ocean events in Ottawa. A semi regular event where there is presentations about FOSS tech and a hackathon to contribute to the related projects. I'd love to know if there are more people in Ottawa that would be interested in similar events. Perhaps if there is enough of us we can try to organize something. Ideally there are some people in Ottawa already familiar with some of these technologies. I spoke with some of the organizers of Boiling the Ocean and they told me the original group started with ~5 people who were already GNOME, PMOS, and Linux contributors but now they have a regular group of ~15-20 people.

For some additional context, I professional work on Mesa3D (https://mesa3d.org/) on a few different graphics drivers like turnip, anv, broadcom, lavapipe/llvmpipe. I would be happy to try and introduce people to working on graphics drivers (in fact I tried to do a little bit of that at Ottawa Systems with my own presentation https://www.youtube.com/watch?v=ohdT2ic39HA). I'd also like to learn more about Linux kernel development, I'm really interested in the new "Mobile Linux" stuff like Postmarket OS. I think it would be fun to work on getting Linux running on mobile phones and making the Mobile Phone experience on Linux better. I'm also a regular GNOME user and would be interested in contributing to some of the software I use regularly.

Besides people who might be working on FOSS on their own I know we have a few companies (big or small) working on stuff that touches FOSS like:

  • Ciena runs Linux on a lot of their networking hardware
  • QNX runs Linux on top of their hypervisor and have been contributing to the linux graphics stack to support virtualisation in this setup
  • WindRiver has their own Linux distro
  • Xilinx/AMD does linux work in Ottawa (I think mainly on the kernel side for xilinx HW, not for AMD GPUs / CPUs)
  • There is Credil (https://credil.org/) in Gatineau who seem to be an open source consultancy
  • Shopify to my knowledge works on a few open source projects related to their frontend and backend
  • like mentioned above we have people from Anubis and Mozilla in the city
  • Also from OCLUG know we have people from Redhat and Lenovo who work on Linux

Maybe you already work on FOSS, you work at one of these places, or you know someone who does he might also be interested in this idea :)


About the other groups: OCLUG from what I've seen focuses more on the Linux user side not really on the developer side. They also used to be a larger but seems to be shrinking now (from an outsiders perspective). The group runs a monthly meeting that centres around a presentation and discussion, typically on more Linux user like topics.

Ottawa Systems is a little closer to the other groups I've mentioned, running a semi-regular event. But its just presentations and its not strictly focused on FOSS. The event has been great for meeting people in the developer community in Ottawa though, like I found out the developer of Anubis (https://anubis.techaro.lol/) is from the Ottawa region here, and we also have Mozilla developer here too!

I also saw hack613 runs some events at the maker space that could be similar to what i'm suggesting here but the schedule seems pretty sparse right now.

Perhaps there is some existing groups in the city that are closer to what I'm thinking about.


I put together a sign up sheet to try and organize a hackfest style event where we would come together to work on a FOSS project together. Please sign up if you're interested! https://cloud.fryzekconcepts.com/index.php/s/tyWLFqb2JQPHoH5

Does matrix have forward secrery now since the switch to MLS? (I.E. the same encryption scheme Singal uses) https://matrix.org/blog/2025/06/dispelling-myths/

They still have a large metadata leak that to my understanding can't be fixed until they introduce stuff like pseudo anonymous user handles and room handles.

Not a good discord replacement but setting up nextcloud talk (simple p2p voice chat) and then the high performance backend (better supports video/voice calls between 3+ people) was relatively easy. We use it among my family now to have group calls instead of relying on facebook messenger.

[–] Hazematman@lemmy.ca 2 points 3 months ago (1 children)

If you use the AIO it comes with the high performance backend already set up afaik.

I run nextcloud using the official release without the docket AIO image, but you can just run the high performance backend from docker. This is what I do on my nextcloud server. https://arnowelzel.de/en/nextcloud-talk-high-performance-backend-with-docker

It's pretty straightforward, just run docker container, if you use a reverse proxy much sure the signaling server is properly configured on the reverse proxy and then modify the next cloud settings to point to the self hosted HPB.

If OP wants voice and video chat like they say they'd have to host synapse and use element afaik.i don't think any of the other home servers support matrix calling. Cinny and fluffychat don't support voice or video calls. Fluffychat has it as an "option" but it's currently broken last time I tried it. Schildi chat might work for voice and video since it's an element fork. I've not tried it so I don't know for sure.

Do you know if there is a more up to date description of xmpp e2ee without having to read the spec. Specifically interested in stuff like how much metadata is leaked.

[–] Hazematman@lemmy.ca 4 points 4 months ago (2 children)

IIRC only Synapse supports video/voice calls and only Element & Element X reliably work for video/voice calls.

Was this images that were auto uploading from a mobile phone? I think the bug was a permission issue in Android, if you don't grant location access it can't get any of the meta data of the photo (iirc).

 

With price of PC components getting more expensive I was thinking of experimenting with a multi-seat type setup on my gaming PC. From what I was reading though, multi-seat requires a dedicated GPU for each seat since the compositor is expected to have an exclusive lock on the card.

Does anyone know if you can do a mult-seat like setup with a single GPU? I have a amd 9070 xt so as far as I know the gpu virtualization thing where you split a single physical GPU into multiple virtual GPUs won't work. I was thinking maybe its possible to have a weak secondary GPU just for display, but I don't know if the second seat would be able to still access the more powerful gaming GPU for rendering.

 

I wanted to share a positive experience with transit. In the last week I had a trip planned and I wanted to try taking transit and see if it would work. I had a flight at 2:25PM to Montreal and I live a short distance away from Tunny's. My wife dropped me off at Tunny's and I took the train and got to the airport in ~50 minutes without any issues.

Now this isn't the fastest (Driving would have only taken ~20 minutes), but man did it feel great to be able to take the train all the way there. It was a very comfortable and smooth ride. I just wanted to share the positive news to let people know its viable and possible.

If there was higher frequency on line 2, I suspect the commute time would have been closer to ~35-40 minutes, make it even more competitive with driving. I'm hopeful for the future of transit in the city :)

 

Hello! My wife and I are currently living in Spain but are going to have a kid soon and looking to move back closer to my family in Ottawa. Ideally we would like to live some place walkable and are looking for some advice on neighbourhoods in Ottawa to explore. My family is in Carlington near Carling & Merivale and I’m not a huge fan on that area, Carling isn’t that pleasnt to walk around and the closest grocery store is Food Basics which isn’t that far away but involves walking around Carling and the 417 exit to get to.

I got some mixed advice about lower town and center town. I’ve heard that they are generally walkable but can be sketchy. Is this true in general? For example is lower town sketchy all over or just around Rideau? Like if we found a place south of Laurier would it be sketchy over there?

Are there other neighborhoods you’d recommend in the city that are walkable? I think the big things for me would be, being able to walk to a grocery store that you can get most of what you need, a pharmacy, and having decent access to transit. We’ll have a car but I really don’t enjoy driving and would like to avoid having to drive on daily basis.
