Telus’ existing KIDC Kamloops data centre holds up to 12,500 GPUs and is capable of generating up to 25 megawatts of power. Its M3 Vancouver facility will be of similar scope, with 13,000 GPUs planned and an output of 26 megawatts. Its downtown location, however, will scale significantly higher, housing more than 50,000 GPUs at a facility capable of generating up to 100 megawatts of power.

This wording has to be a mistake. Datacentres don’t generate power. They consume it.

I tried SilverBullet and it was really good and really neat, but not for me. Now I’m using Obsidian, which is easy enough to self host, but the company that makes it is small and indie and I decided to support them with a subscription.

I also switched to Asahi Linux 5 months ago. After decades of being an Apple fan, they are most unappealing these days.

I've been running my own email server for 15+ years. One year ago I needed to change VPS providers and thus get a totally different IP. I worried about this a bit, but actually had no issues whatsoever. Of course, I wasn't starting completely from scratch as I had the same domain, all my personal experience, and a battle-tested configuration for docker-mailserver. But yeah, the lack of IP reputation itself didn't seem to be an issue at all. Maybe I got lucky. Or maybe it's because I chose a relatively small Canadian VPS provider rather than one of the global cloud giants (I assume their IP address space gets pretty trashed with scammers).

All MTAs have retries baked in, so running a self-hosted email server that receives mail is actually one of the most forgiving services in this respect. If your server is offline, the sending server will retry several times over 24-48 hours before it gives up. Even the big cloud email providers will do this.

That said, there are other aspects of running an email server that require some extra rigour, but they're more on the sending side (making sure emails you send to other people actually land in their inbox). Doable, but one of the more challenging things to self-host.

Yay! I’m following Avi and Emily now too. Although I was hoping they’d choose socialbc.ca as their mastodon server!
