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.

[-] JuvenoiaAgent@lemmy.ca 62 points 1 year ago

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

  • 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.

[-] GONADS125@lemmy.world 80 points 1 year ago* (last edited 1 year ago)

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.

Thanks, will put this in the post

[-] quaddo@reddthat.com 22 points 1 year 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" :)

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

Great work.

[-] cerberus@lemmy.world 46 points 1 year ago

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

[-] randint@feddit.nl 45 points 1 year 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.

[-] ruud@lemmy.world 40 points 1 year ago
[-] randint@feddit.nl 27 points 1 year 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

[-] ruud@lemmy.world 35 points 1 year ago

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

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

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?

[-] miket@lemmy.world 33 points 1 year ago* (last edited 1 year 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 to handle more users at the same performance.

More importantly; they may help 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.

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.

[-] Scotty_Trees@lemmy.world 26 points 1 year ago

Looks like the upgrade is done and was a quick and easy success, thank you Devs!

[-] Cold_Brew_Enema@lemmy.world 26 points 1 year ago

How do you turn on endless scrolling? I'm still seeing page numbers

[-] SportingChap@lemmy.world 15 points 1 year ago

Number 1 thing I miss from reddit w/ RES. 😫

[-] drdabbles@lemmy.world 21 points 1 year ago* (last edited 1 year ago)

Infinite scroll and word filtering. If I see one more post about "AI", Musk, Twitter, or fake superconductors, I might have to get off the computer for 10 whole minutes.

[-] AlexisFR@jlai.lu 12 points 1 year ago

Post hiding would be great to have.

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

Smooth! Curious about the new DB size

[-] ruud@lemmy.world 55 points 1 year ago

Down from 12GB to 1.8GB....

[-] sv1sjp@lemmy.world 18 points 1 year ago

Wow, thats awesome for the backups and scalability!!

[-] ruud@lemmy.world 22 points 1 year ago

Me too. Creating a db dump now..

[-] lemmy@coeus.sbs 18 points 1 year 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.

There is an official announcement here: https://lemmy.ml/post/2540874

[-] Machefi@lemmy.world 11 points 1 year ago

If announcements of Lemmy releases are what you're after, !announcements@lemmy.ml is a place for you. But in broader picture, subsequent updates are usually just not that big of a deal.

[-] Rentlar@lemmy.ca 8 points 1 year 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 !Fediverse@lemmy.ml, someone would likely post up there after the fact if the server is down for a while without apparent explanation.

Thanks as usual for the transparency, y’all.

[-] Nix@lemmy.world 15 points 1 year ago

Awesome! It’s great to see thing become snappier and better since I joined Lemmy.

Reddit would almost never update unless it was a pants on fire situation or they would force feed features that no one wanted or even was tested properly.

A big thank you to everyone involved, FROM those taking the time to submit bug descriptions in a reproducible manner and those making feature requests or those simply upvoting and pointing out the most needed patch/updates TO simultaneously amateur, newly minted coders and veteran developpers pushing small and big patches to fix anything from typos, reformatting old code, cleaning almost unnoticeable UI object, transition less performing backend modules or secure/harden of all these moving parts.

I am glad to witness and be a part of the perpetual progress of the fediverse.

[-] coconutxyz@lemmy.world 14 points 1 year ago

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

[-] Molecular0079@lemmy.world 10 points 1 year ago

Yes, the 0.18.3 changelog has Fixing hot_ranks and scores to append a published sort as one of the items.

Maybe I’m missing it, but I don’t see the option for infinite scroll anywhere. How do I add that?
