The next Nix Hour is tomorrow (https://www.youtube.com/live/Gj5LrUmDzHM), still at the same time as before, 14:00 CET. I will close the above poll before the session though and announce the new time based on the results.
The new time is decided now, it’s going to be Monday Tuesday, 19:00 CEST! As also announced in the last Nix Hour, let’s take a week break though, the next session will be in a week: https://www.youtube.com/watch?v=aQJE4ZxD3cc
As always, I encourage you to join the meetings (meeting link) to ask questions directly. But you can also ask questions in advance by opening issues in GitHub - tweag/nix-hour: Questions for the weekly Nix Hour 
Made a mistake, it’s Tuesday, not Monday! I corrected the above message
Since nobody joined the last Nix Hour, despite polling for a better time, and from some feedback on YouTube, I decided to create a Matrix channel for notifications. So if you want to get a notification about an hour before the Nix Hour starts, join #nix-hour:matrix.org! This room can also be used for any Nix Hour-related discussions or feedback.
Since we have a Matrix room now, I’m not sure if I should continue posting these messages here to inform about the Nix Hour, but for today I still will:
The next Nix Hour is tomorrow, Tuesday 19:00 CEST in this Jitsi or live on YouTube.

The Nix Hour has continued weekly since the last message, and the next one will be today in ~1.5 hours at 19:00 CEST in this Jitsi (best if you have questions yourself) or live on YouTube if you just want to listen in!
Due to me going on a vacation, the following two Nix Hours will be skipped however, leading to a timeline like this:
- 2023-06-20 (today): Nix Hour #34
- 2023-06-27: Skipped!
- 2023-07-04: Skipped!
- 2023-07-11: Nix Hour #35
In case you’re wondering where the Nix Hour went next week and when it is expected to be back

Happy to help!
Just a note that we will not have a Nix Hour next week since I’ll be traveling for Nixcon.
But I will have a lightning talk at Nixcon to talk about the Nix Hour!
Edit: I felt sick and couldn’t have the talk, maybe next year
So we expect the next Nix Hours to be like this:
- 2023-08-31T16:00:00Z: Nix Hour #42 (meeting for questions, stream)
- 2023-09-07T16:00:00Z : Skipped for Nixcon.
- 2023-09-14T16:00:00Z : Nix Hour #43

Because we keep running into various problems with the main Jitsi instance, I decided to switch to a different instance this week, https://meet.init7.net/. The instance is hosted by a very loved and techy ISP provider in Switzerland, so not only do I trust them, but it’s also very close to me, so the delay should be smaller too!
In addition to more stability, it also won’t require any authentication, and there won’t be a message about the room name being insecure.
New meeting link: https://meet.zrh.init7.net/nix-hour
Next meeting time: 2023-09-14T16:00:00Z

Quick announcement: Today’s Nix hour is in ~15 minutes (2023-11-16T17:00:00Z), but we’ll switch it up a bit this time:
- The first 30 minutes won’t be recorded but I’ll hang out in the meeting, feel free to join, ask and chat however
- The second 30 minutes will be streamed/recorded here, and I’ll try to build a small lecture about some question that came up earlier during that
Let’s see how it goes!

We’re going to try out something different for tomorrow’s Nix Hour at 2023-11-30T17:00:00Z: We pick a topic beforehand and will then focus on that single topic for the entire episode.
This time, we’re going to talk about writing NixOS modules! If you have any questions about this topic, you can either:
- Comment with your question in this issue
- Join the meeting and ask via voice or chat
And as always, it will be streamed to YouTube here if you just want to listen in.
If this new format of picking the topic beforehand and focusing on that works well, we intend to keep doing this going forward. If you have any feedback, feel free to give it here or on Matrix! And if you want to suggest another potential topic for a future Nix Hour, open a new issue!

A beginner guide in general would be pretty cool! Working with Nix internals too would be cool, get into the weeds of things ig :3
The next Nix Hour is 2023-12-14T17:00:00Z, and we’ll talk about Debugging Nix code!
If you have any questions about this topic, you can either:
- Comment with your question in this issue
- Join the meeting and ask via voice or chat
And as always, it will be streamed to YouTube here if you just want to listen in.
Updates
Holiday Break
We’ll have a 2 weeks break after this week, so the following Nix hour will be in January, Happy Holidays! 
New schedule
We’re changing the day and time of the Nix hour every month going forward. But instead of making a poll every time like we did previously, we’re just going to pick pseudo-random times. This will hopefully allow people with other availabilities to join more often.
Following Nix Hour
For January we picked 15:00 CET on Fridays! This means that the following Nix Hour after this week will be on 2024-01-05T14:00:00Z and repeat for 4 weeks until a new time is announced for February!
Weekly topic
The weekly topic will continue to be selected in advance from the list of open nix-hour repository issues. So if you want to suggest a topic, 
existing issues or write your own!

Only live stream, no more Jitsi meeting
Unfortunately we’re retiring the Jitsi meetings for now. They’re causing too many problems and don’t encourage a lot of interaction. Instead, watch the stream live on YouTube and use the live chat to ask questions about the session and interact with others.
In the future we also hope to have an alternative to YouTube, see here for updates regarding that.
Day and time in February
The Nix Hour gets a new day and time every month in order to allow people with different abilities to watch it live.
For February, the Nix Hour will be 16:00 CET on Wednesdays! So the following Nix Hour after this week will be on 2024-02-07T15:00:00Z and repeat for 4 weeks until a new time is announced for March.
The next Nix Hour is 2024-02-07T15:00:00Z, where we’ll continue with part 2 of Advent of Code Day 1! Watch the stream and use the live chat for any questions
