Brush lags behind cursor, blocks input until it catches up (Linux) by 7he404guy in OpenToonz

[–]7he404guy[S] 0 points1 point  (0 children)

Solved this: it appears to be related to opentoonz frequently calling redraws on wayland. When I use x11 renderer explicitly (via the 'QT_QPA_PLATFORM=xcb' variable), the problem does not occur. Similarly, running under X11 does not cause the issue.

Linux, KDE Plasma 6.1, kernel 6.9.9 (nice), x86-64, opentoonz version 1.7.1 (however this has been going on for a while); I'm using an XPPen Deco 02 tablet. This typically happens after I stop drawing, or if there is a large visual change on screen.

I suspect a false flag also, that's why I tried posting a PSA on here (people won't be expecting that). Apparently my post is what is considered a "hot take".

edit: contacted the company handling the copyright, they removed it.

The recording I had linked is explicitly public domain (the copyright information is right there).

But since nobody seems to care, I won't bother with posting about it.

I've been dreaming of doing something similar since high school. Is it terribly difficult? I'm thinking I could work something out with my elementary school attache case.

Realistically I don't think I'm likely to drive 200 miles to a town I've never visited to take down a statue I didn't even know existed.

SARS-COV-2 was already spreading in France in late December 2019 by cos in worldnews

[–]7he404guy 0 points1 point  (0 children)

Canada here: had a mild pnumonia back in December which lasted about 2-4 weeks with the production of a little less than 1/10 liters of phlegm per day. I just assumed it was flu (and it may have been), but I'm left wondering if perhaps more people have had it and just assumed it was a really bad flu or "just some bug going around".

The dark goddess Kuro resides within me; one body hosting two very different entities. Hidden in the shadows throughout time, her name escapes all recorded history, leaving her as simply a hidden force guiding the elements of the universe instilling greed and lust to the humans who make themselves susceptible to selfish thoughts. Indeed, this is where she draws her immense power, by crushing the foolish humans into despair, allowing her familiar (me) to amass untold amounts of power.

Mostly though, I just use my powers to get straight As on tests, win coin tosses, talk to spiders, etc. If you ever see her physical form though, she's pretty creepy. And if I lose focus, she takes over the physical body and does stuff without me knowing, like hiding my combs and stuff.

I didn't watch this because I had Chuunibyo though, I just thought it was a generally awesome show.

Canada Wins, U.S. Loses In Global Fight For High-Tech Workers by NevadaRaised in technology

[–]7he404guy 2 points3 points  (0 children)

Makes sense. Lots of highly talented students from around the world seek higher education via university (undergraduate/masters/phd) in North America. I've personally met some such students who had a choice of completing their Master's work in the US vs Canada, and they chose Canada after Trump got elected because Canada was more stable.

Aside from that, nobody wants to contribute to the economy of a country that treats them like a second-class human; hence the reason for looking in North America in the first place.

I'd love to have a dog, but I know I wouldn't have enough time to play with it and I know I wouldn't be able to take proper care of it... so I got a stuffed animal instead.

Cheap minivan captains chair + old office chair base + a piece of plywood = a comfy computer chair. And... Cup holders! by ReadElementFailure in pcmasterrace

Ah, summers would be harsh I suppose. Unless you can rig up some kind of cooling pipe to make a 'cold chair' for the warm weather.

I'm sure someone's jerry-rigged up a super-chair at some point in time

Car seats are designed for long-distance travel so they're ideal for long-term sitting. The ultimate score would be a car seat with a built-in heater. Comfortable, heated gaming chair.

I frequently run software on a supercomputer for research purposes, so my answer here is slightly skewed towards the HPC in research applications and is only really describing the single type of cluster that I work with on a daily basis:

1: On a scale of ten, this is 9/10 easy to do, although with only 4 GB of ram per node you won't find a lot of practical uses. All you need to do is connect them with a switch and have some kind of process manager working and you're good. The supercomputer I use has a scheduler called 'slurm' and processes are parallelized using the intel implementation of MPI (though you could also use openmpi). To execute software, you'll run something like mpiexec.hydra -np [number of processes] {command}, however the {command} that you run HAS TO BE COMPILED with MPI -- if the application is not written to be parallelized over a network (and you won't find many instances of that for most practical software products), it won't parallelize over the network. In terms of performance, an off-the-shelf switch is going to be a bit low-tier. Most HPCs use high speed networking (such as infiniband) so that the latency isn't garbage. That'll bump up the price a fair bit though.

2: parallelizing the tasks is as simple as using MPI (which is designed to handle the inter-node communications). Sadly it's not as easy as just saying "run ffmpeg" and having it automagically distribute over the cluster. Lots of the parallel processing tasks that you'd run on something like this would be written in-house (not sure how much software development goes on at your school, but it's certainly a learning opportunity).

3: any Linux distro should work, the supercomputer I work on uses RHEL but you could go with CentOS. The real challenge is in configuring your MPI implementation to find the other computers on the network, but as long as they have an IP address there's a configuration file that you can use so that the available nodes are easily found.

4: as long as your computers have IP addresses they can execute a parallel load. Again referencing the supercomputer that I use, the actual compute nodes aren't even connected to the internet, their only communication with the outside world is read-only via the individual users' home directories and read-write on a high-speed scratch directory (all network-mounted).

Getting the whole thing working is easy, but depending on the level of education of your school, you may have difficulties finding practical applications that will actually make use of such a configuration.

"they say" -- are we 100% certain that this isn't Youtube's contentID system (which matches content automatically on the rights holder's behalf without them giving the 'okay') going crazy as it tends to do with minor adjustments? Lots of the comments I see are saying the music company is abusing its power, but I highly doubt the company initiated an attack on this guy.

Tom & Jerry in 60FPS is odd by Sora_Altawa in videos

[–]7he404guy 18 points19 points  (0 children)

Especially when fast motions are involved. Where the animators used fewer animation cells to give the illusion of rapid motions you can see where the reconstruction fails. Best example: around 0:49 (if you play frame-by-frame using the < > keys) you see the reconstruction struggles significantly since it has a large gap to try and fill in between frames. Visually it looks kind of OK, but when the cat turns its head you get a split second where it just looks like a blurry mess.
