Update The upgrade was done, DB migrations took around 5 minutes. We'll keep an eye out for (new) issues but for now it seems to be OK.

Original message We will upgrade lemmy.world to 0.18.3 today at 20:00 UTC+2 (Check what this isn in your timezone). Expect the site to be down for a few minutes. ""Edit"" I was warned it could be more than a few minutes. The database update might even take 30 minutes or longer.

Release notes for 0.18.3 can be found here: https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md

(This is unrelated to the downtimes we experienced lately, those are caused by attacks that we're still looking into mitigating. Sorry for those)

Sorry for those

It's not your fault :) We know you admins are working really hard to keep the server as stable as possible.

[-] [email protected] 10 points 11 months ago

Don't humanize them, they'll expect us to always treat them with respect! /s (obvs ๐Ÿ™„)

  • Add controversial ranking
  • Change logic for determining comment default language
  • Add infinite scroll user option

Neat. I hope the comment language logic change means the default won't be "Undetermined" anymore.

Thanks, added to the post

I'm sure the attacks are just as annoying for you guys as they are to us, if not more. Appreciate the update.

Edit: Loving the endless scroll for the front page! I've been eagerly awaiting that. Such a small change, but such a big impact.

[-] [email protected] 21 points 11 months ago

Minor suggestion: write your time zones like UTC+2 and not CEST. I'm pretty sure most people outside Europe don't know what the time zone CEST is. Yes, you provided a link that helpfully converts the time to the users' local time zone, but sometimes it's nicer to be able to know something without having to click into a link.

[-] [email protected] 8 points 11 months ago
[-] [email protected] 14 points 11 months ago

Wow, you actually changed it! I was kind of shocked when I came back to my feed seeing UTC+2 in the title. Thanks! :D

[-] [email protected] 12 points 11 months ago

Yep, I like good tips like these. :-) Thanks

[-] [email protected] 2 points 11 months ago

Super nitpick. Can we just use 1800 utc? Then everyone can convert to their zone directly. *signed me in a CEST zone.

[-] [email protected] 2 points 11 months ago

I keep one of my spare clocks set to UTC for exactly this.

it would be nice if Lemmy had support for formatting Unix timestamps in whatever timezone whoever is looking at it is in, like discord

Thanks, will put this in the post

[-] [email protected] 8 points 11 months ago

Fwiw, it can be helpful to call out the date for such changes. Preferably in YYYY-MM-DD (ISO 8601).

While it's helpful to link to an off-site timezone converter tool (thanks for that, btw), "today" can be a different date, depending on where in the world you are. For example, Japan, Australia, and New Zealand.

Even better is "when this post is N hours old" :)

[-] [email protected] 13 points 11 months ago

Great! Thanks for keeping things up to date and running!

[-] [email protected] 11 points 11 months ago* (last edited 11 months ago)

Thank you for the heads up!!

2pm EST for us silly Freedum Unit folks.

[-] [email protected] 8 points 11 months ago

oh yeah, forgot about that. Could've just put ET.

Lol. Word is the update gives a boost to smaller communities. Looking forward to this!

[-] [email protected] 8 points 11 months ago

Thanks for all the fine work, dudes

This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%.

Is it me or is the 80% figure just insane? Are there any benchmarks to see how fast this has become versus say Lemmy 0.18.2 on a very large instance?

[-] [email protected] 8 points 11 months ago

Funnily enough, this is the feature that can speed up the performance by doing less calls:

The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing POST requests, and also reduce server load.

[-] [email protected] 7 points 11 months ago

Is it me or is the 80% figure just insane?

Not really, you'd be surprised how often systems are bloated all because of a single option, character, etc. Most developers don't start optimizing until much later in the software's lifecycle. Often enough, it is easily overlooked. That's why code reviews are needed often with fresh pair of eyes.

Just to set the expectations, reducing database size or CPU usage does not necessarily mean it is faster but it does mean there's more free capacity on the servers with handle more users at the same speed. More importantly; they may reduce costs on the smaller indie instances that doesn't need to buy larger server instances.

Hopefully, we'll continue to see more of these optimizations.

Will it change the behaviour of sorting by hot? seeing post from years ago is funny

[-] [email protected] 5 points 11 months ago

the best server! thank you

[-] [email protected] 4 points 11 months ago

Why are these announcements the only place I am finding out the Lemmy has an update? I figured there would be more top level discussions about it on Lemmy. Maybe I am just not following the correct communities.

[-] [email protected] 4 points 11 months ago

Each server admin decides how to publish announcements, some have a mastodon account, some have a separate website, some might post on a different Lemmy server, like [email protected], someone would likely post up there after the fact if the server is down for a while without apparent explanation.

Really liking the transparency with the community over how the server is doing.

Great work.

[-] [email protected] 3 points 11 months ago

Will calckey.world be renamed as well, as upstream abandoned the calckey name?

[-] [email protected] 7 points 11 months ago

Not renamed. A new server will be started where ppl can migrate to. Yet to determine a new name as firefish.world is taken..

[-] [email protected] 4 points 11 months ago

I'm curious about this as well. I've looked into Firefish a bit and it looks interesting, but I can't seem to follow Lemmy communities from the flagship instance Firefish.Social.

Works on calckey.world, though.

A website which should let you check what time that is for your local time zone; although I used Central Europe Summer Time (CEST) instead of Central Europe Time (CET) and I'm not sure if that's right.
