This week's headliner change is something that I think will make a lot of people happy: better fractional scaling! Vlad and Xaver have been hard at work to snap everything to the screen's pixel grid, with the effect that using a fractional scale fact…This Week in Plasma: Better fractional scaling

Not really. The reason is that Steam (and an unfortunate number of other programs) run through Xwayland when your compositor is using Wayland. If you then use fractional scaling, Xwayland will render at the fractional of your resolution and will be scaled linearly to your display. This results in general bluriness for X11 applications.
Kwin, to my knowledge, is the only Wayland compositor that allows decoupling Wayland scaling from Xorg (and does so by default). While this results in different scaling behaviour for X11 apps, it does mean they are never blurry.
If you then use fractional scaling, Xwayland will render at the fractional of your resolution and will be scaled linearly to your display.

Oh shit I haven't seen anything from hilariouschaos in forever even tho I sort by new and new comments all the time.
I thought the instance died. Good to see y'all still here
It would be more useful to see metrics weighted per active user it's trivial to update a server if it's just for yourself, and likewise it's easy to let it lag a few versions behind.
What's more relevant is the version number the large instances are running

You can filter fedidb.org/software/lemmy by monthly active users.
- lemmy.ml, hexbear and Lemmy dbzer0 are the only ones in the top 10 to run 0.19.8
- discuss.tchncs.de, lemmy.zip and sopuli.xyz, infosec.pub are in the top 20 and run 0.19.8 as well
Note: 0.19.6 and 0.19.7 had an issue with pictures thumbnails, which is why quite a few instances kept running 0.19.5
The elephant in the room is obviously LW which hosts around a third of the monthly active users but still run 0.19.3
A month ago someone asked about this on !support@lemmy.world, for people interested: lemmy.world/post/22173840
Edit: added hexbear, discuss.tchncs.de and infosec.pub which just updated

Ya, my whole server was in a bad mood after 19.4.
I'm on 19.5 which one should I go with (I mean if 19.6 had problems there is maybe a 19.6.1 right?)?
Yes that's the theory 😊 but I heard icons or something doesn't work well on 19.7...
Do they do backports?
There used to be an issue on thumbnails for some instances
- lemmy.cafe/?dataType=Post&list…
vs
- sopuli.xyz/?dataType=Post&list…
But on the other hand, some instances on 0.19.7 were doing fine:
- lemm.ee/?dataType=Post&listing…
Not sure about backports
- people are changing instances
- some instances shut down
- some farmbots were open
My theory is that there is quite a few servers that are chosing to defederate. The number of total servers continues to drop according to fedidb.
Or admins are just finding it not worth bothering with administering their own server and turning them off.

Japanese researchers test pioneering drug to regrow teeth
Unlike reptiles and fish, which usually replace their fangs on a regular basis, it is widely accepted that humans and most other mammals only grow two sets of teeth.But hidden underneath our gums are the dormant buds of a third generation, according to Katsu Takahashi, head of oral surgery at the Medical Research Institute Kitano Hospital in Osaka.
[…]
Tests on mice and ferrets suggest that blocking a protein called USAG-1 can awaken the third set, and the researchers have published lab photographs of regrown animal teeth.In a study published last year, the team said their "antibody treatment in mice is effective for tooth regeneration and can be a breakthrough in treating tooth anomalies in humans".

Incus 6.8 has been released
Incus is a next-generation system container, application container, and virtual machine manager.
It provides a user experience similar to that of a public cloud. With it, you can easily mix and match both containers and virtual machines, sharing the same underlying storage and network.
Incus is image based and provides images for a wide number of Linux distributions. It provides flexibility and scalability for various use cases, with support for different storage backends and network types and the option to install on hardware ranging from an individual laptop or cloud instance to a full server rack.
When using Incus, you can manage your instances (containers and VMs) with a simple command line tool, directly through the REST API or by using third-party tools and integrations. Incus implements a single REST API for both local and remote access.
The Incus project was created by Aleksa Sarai as a community driven alternative to Canonical's LXD.
Today, it's led and maintained by many of the same people that once created LXD.

I don't understand what you mean by "epic pile of hacks". Proxmox is just a Linux distribution, with a particular focus. All the software is the usual stuff with integration scripts and binaries and a webby front end. They start off with stock Debian and work up from there which is the way many distros work.
I'm not sure what Proxmox switching to Incus would really mean. They are both Linux distributions that focus on providing a VM and container wrangling system.
I happen to be porting rather a lot of VMware to Proxmox. My little company has a lot of VMware customers and I am rather busy moving them over. I picked Proxmox (Hyper-V? No thanks) about 18 months ago when the Broadcom thing came about and did my own home system first and then rather a lot of testing. I then sold the idea to the rest of my company and we made some plans and are now carrying those plan out.
Now, if Proxmox becomes toxic, I still have projects like Incus to fall back on. I ... WE ... have choice, and that is important. You can be sure that if Proxmox drops the ball, Veeam will suddenly support Incus or whatever the world decides is the next best thing in Linux VMs and container land.
I was a VMware consultant for 25 odd years. No longer (well I am still but only under mild protest!) I also have to wrangle a few Hyper-V clusters too. All of these bloody monolithic monstrosities work at the whim of massive corporations who really don't have your best interests at heart. They bleed you dry.
I like to have choice. Proxmox and Incus are both examples of choice. You start off with "I'd like to run VMs and containers on my hardware with software that is "open" and you have more than one option. You do not start off with: "I'd like a HyperV or VMware", nail your colours to the mast and live in a rather rubbish monoculture.
Sorry, I seem to have gone on a bit 8)
Well... If you’re running a modern version of Proxmox then you’re already running LXC containers so why not move to Incus that is made by the same people?
Proxmox (...) They start off with stock Debian and work up from there which is the way many distros work.
Proxmox has been using Ubuntu's kernel for a while now.
Now, if Proxmox becomes toxic
Proxmox is already toxic, it requires a payed license for the stable version and updates. Furthermore the Proxmox guys have been found to withhold important security updates from non-stable (not paying) users for weeks.
My little company has a lot of VMware customers and I am rather busy moving them over. I picked Proxmox (Hyper-V? No thanks) about 18 months ago when the Broadcom thing came about and did my own home system first and then rather a lot of testing.
If you're expecting the same type of reliably you've from VMware on Proxmox you're going to have a very hard time soon. I hope not, but I also know how Proxmox works.
I run Promox since 2009 and until very recently, professionally, in datacenters, multiple clusters around 10-15 nodes each which means that I’ve been around for all wins and fails of Proxmox. I saw the raise and fall of OpenVZ, the subsequent and painful move to LXC and the SLES/RHEL compatibility issues.
While Proxmox works most of the time and their payed support is decent I would never recommend it to anyone since Incus became a thing. The Promox PVE kernel has a lot of quirks, for starters it is build upon Ubuntu’s kernel – that is already a dumpster fire of hacks waiting for someone upstream to implement things properly so they can backport them and ditch their own implementations – and then it is a typically older version so mangled and twisted by the extra features garbage added on top.
I got burned countless times by Proxmox’s kernel. Broken drivers, waiting months for fixes already available upstream or so they would fix their own bugs. As practice examples, at some point OpenVPN was broken under Proxmox’s kernel, the Realtek networking has probably been broken for more time than working. ZFS support was introduced only to bring kernel panics. Upgrading Proxmox is always a shot in the dark and half of the time you get a half broken system that is able to boot and pass a few tests but that will randomly fail a few days later.
Proxmox’s startup is slow, slower than any other solution – it even includes management daemons that are there just there to ensure that other daemons are running. Most of the built-in daemons are so poorly written and tied together that they don’t even start with the system properly on the first try.
Why keep dragging all of the Proxmox overhead and potencial issues, if you can run a clean shop with Incus, actually made by the same people who make LXC?
If you’re expecting the same type of reliably you’ve from VMware on Proxmox you’re going to have a very hard time soon.
Try upgrading a v6.0 or even 6.5 ESXi from the command line. If there is no "enterprise" iLO or iDRAC or whatever with media redirection then you'll be jumping in the car. Or what about if, back in the day, you went ESX instead of ESXi? lol!
How often do you find yourself repairing a vCentre? Oh dear the SSL certs are fucked again, despite being fixed a few years back. Yes I can bring the bloody things back but I've also got longer Linux experience than VMware. Those 14 virty discs were a daft idea and let's dump the logs to all sorts of random areas and then stir them around every few versions. ... and its 400GB in size - even thin provisioned they are still huge for what they do.
How about when the Dell customised .iso was the only way to install on Rx10 hardware and then made the box unupgradable years later? or when the Intel NIC drivers got a bit confused - yay - PSoD?
Reliability: don't make me laugh!
I'm in the same boat, I tried Incus or rather LXD a couple months back and gave up after a little while due to pressing business needing the Proxmox machine up again.
I have two main requirements which I have for my server:
- It must support Home Assistant OS as a VM and a USB Dongle (Zwave)
I found this as a possible solution for LXD systems:
seanblanchfield.com/2023/05/ho… - It must support NFS exports so I can share my storage and data drives.
I'm pretty sure since it's on Debian, I can install Cockpit and it's sharing plugin for this.
I think the thing which scared me off at the time too was the lack of GUI which I think I may have missed. This may be a solution:
blog.simos.info/how-to-install…
I was just thinking about Incus the other day so this might be a good time to look into it more!

My setup is in an old garden shed I've converted to my tech studio.
I added insulation, radiant barriers, lighting, air conditioning, and have three 3d printers, a laser cutter, and a workstation for my laptop with a wide-screen monitor along 2 sides, and a workbench and tool wall on the third.
Whole conversion probably cost about 1200 in materials, and it's amazing.
3 3d printers, a laser cutter, a workstation, a wide screen monitor, and an ac for under $1200?
Just trying to figure out what exactly that $1200 covers.
I never understood the obsession with multiple screens. Isn’t it better to be obsessed with one giant screen? That way you don’t get black bars in front of you.
Edit:
I got to clarify. I’m talking about a single ultra wide screen with high resolution but also scaling so texts aren’t super small. There are gaming ones that are OLED so great color and performance. Both windows and Mac OS have software that lets you split in half or 1/3 + 2/3 (which you can’t do with two screens).
It’s ultra wide so you can look left and right and not top and bottom.
If you’re connecting a laptop, you’ll have a tiny screen for slack or a video or something.
I do agree that it’s more expensive.
- Resolution - having a big screen at the same resolution doesn't really mean much, and you usually don't really go higher than 4K for computer monitors. Yes, there are 8K TVs, but good luck being able to afford one.
- Performance - if you want to go big, you're probably thinking of TV screens, and TVs generally just aren't built for colour accuracy, low latency, or high refresh rates.
- Cost - bigger computer monitors are pricier. Besides, if you are upgrading your monitor anyways, well, your old one can just become your secondary display; it's free screen estate.
- Ergonomics - it takes less effort to look from side to side than it is to look up and down. With multiple smaller screens, you can arrange them all to face you cockpit-style; with a giant screen, the edges will look distorted unless you buy a curved display.
- Software - most OSs can snap windows to the four quadrants of each display; anything smaller or more unique, and you will have to manually resize each window.
- Practicality - if you're working, gaming, or watching a movie, you want to dedicate an entire screen to your task at hand. Having multiple monitors lets you do that while still being able to check other things on the side. For example, when I stream games, I can play while having my OBS and Twitch stats on the side; when I do any design work, I can pull up references on my secondary display. The black bars are a non-issue.
On my desk at work I have an ultra wide, a single external laptop screen to my right and a TV on the far wall on my left.
Snapping two apps right and left on the uw is fantastic on the ultra wide. Price aside, it's as good or better than having two monitors.
The TV obviously doesn't count cuz it's only there for other people or if I want to have server graphs running for show.
But the secondary monitor works really well is a semi important parking space. I usually slide slack and signal over there. That way I can see what was sent and only worry about going over to it if it's something I need to respond to. I find it kind of nice to have that logical division over there. I can hot key stuff over that monitor.
I'd say if someone has the money the UW is fantastic, But it's super useful to have a secondary monitor from a mental standpoint for me at least.
On my desk at work I have an ultra wide, a single external laptop screen to my right and a TV on the far wall on my left.
I have a TV on the side (rarely use it) and my laptop below the screen.
I do agree, it’s great having an on the side screen. My point was more about having one big main screen instead of few main screens. I used to have two identical screens side by side. I ended up just looking right most of the time so I thought one big screen was the answer.
Interesting, I have two identicals at home and tend to use them equally.
Where do you put the split, to one side or directly in front of you?
Yes, otherwise it wouldn’t fit properly and the asymmetry would bug me.
I’ve also worked in office spaces with multiple screens, it’s always put symmetrically in my experience. So you always have to have your head tilted.
Imo if you put it asymmetrically, as in one main screen in the centre, then that’s pretty much what I’m talking about, I just want a UW in the centre cause it’s a better experience.
In this post’s picture, I do like that a screen is in the centre but it’s too small imo, rather have a bigger one.

First, they observed brain activity while the mice were resting. Stress had changed the activity in the amygdala of the less resilient mice much more than it had in the resilient ones.When the researchers gave the mice a choice between plain and sugar-sweetened water, the resilient mice easily chose the sugar water. But the less resilient mice became obsessed and often opted for the plain water.
Xia looked at brain recordings of the mice who chose the sweet water. Their amygdala was communicating with a nearby brain region called the hippocampus that remembers and predicts.
She saw a different pattern in the mice that could not decide whether to drink the plain or sweetened water. In those mice, the conversation between the two brain areas sputtered.

How to Make Your First Loops Video
For those interested in trying out #Loops, you may be wondering: what are good tools or processes for making videos?
We go into detail with some of the tools we're currently using.
You might want to try CapCut. It's by ByteDance, used by a lot of Tiktokers, and some of the better features are behind a paywall, but it's probably one of the brightest examples of an easy-to-use mobile editor for Android.
I still haven't found a whole lot of alternatives to that. There's some professional-grade multi-track editors, and some rinkydink open source apps that barely do anything. Honestly, it's kind of hard to find a good balance.

Lukewarm take at best. It's cool if it's not for you personally, but a lot of people use it, love it, and benefit from it.
I think the stuff that Loops is building out could eventually become a standard feature that a lot of Fediverse platforms optionally offer. That kind of interop for the people that want it is frankly a win.
Social media needs testing like any other software. If you join Loops now, you're basically a beta tester.
Testing social media without users makes little sense.
There's also an argument to be made that when it is finally released properly, it's good to have some content there already.
I am a little concerned about the future of Loops and Pixelfed though. Developing things can be fun, maintaining them is a different story.
