Same here. I really should spend a few hours to finalize the tuning, but it prints ok enough that it's not really worth doing it.

People also still use Meta products, Apple products, Amazon and their products, and so on, even though all of these companies directly support the budding fascist empire in the USA.

Likely, you too buy/use products by a corporation that supports the pumpkin dictator, and that has much more real-world effect (on trans people and on all other minorities too) than the ramblings of a mad old TERF.

At least Rowling isn't directly stoking the genocide in Gaza or rounding up and deporting people to prison camps in other countries.

(I'm not defending Rowling. I'm just saying at a certain point most people, likely including you, value the convenience of next-day-shipping over the life of some people we don't know.)

Yeah, fair, I just wanted to make sure nobody has wrong expectations. Back when the Prusa Mini was new, off-the-shelf printers were much worse than they are today, and DIYing a printer could actually be a good deal if the goal was to have a good printer (and not specifically something to tinker with).

Nowadays, if you DIY a printer it's going to be more expensive while performing worse than an off-the-shelf printer.

Wayland has been around for many many many many more years than Wayland has been good enough to use. I think that’s about it.

I think that's mostly it. When Wayland was first released, it was barely in an alpha state, with many major use cases not being supported at all. Since Wayland is a deep system component, it requires apps to adjust to them, and in the beginning this hadn't happened at all so far, so really nothing worked.

And this didn't change over night. That easily took a decade, and still today some use cases still don't work well (e.g. accessibility/screen reader compatibility).

There's not a lot left from the original Ender 5.

I kept the frame and the steppers, belts and lead screw.

The wheel are replaced by MGN rails. The mainboard is now an Octopus v1.1. The print head is replaced with an E3D toolchanger with E3D v6 hotends, direct driven with TBG-Lite extruders. The toolchanger does bed levelling with a simple endstop mounted to the toolchanger in a way that it can reach the bed if all tools are parked.

The only remaining hardware issue is that I'd like to have a second Z motor.

I don't really consider my printer an Ender 5. It's more of a Ender-of-Theseus. It's basically a DIY design built on top of an existing frame.

But the real issue is software tuning. It's just so complicated and time intensive to tune all the dozens of parameters (speed, acceleration, linear advance, retraction, input shaping, auto bed levelling, tool offsets, ...).

Modern budget printers like the A1 are so amazingly good that matching their out-of-the-box performance and calibration takes a huge amount of time if it even is possible.

I easily spent 100+h reconstructing and tuning my printer, troubleshooting problems so obscure that I couldn't find anyone on the internet who talked about them before. Been working on this printer for about 4 years or so.

And the other day a friend of mine who received his A1 a week ago shows me the perfect quality multicolor prints that his cheapo A1 did after half an hour or so of setup.

Tbh, by now I would recommend against DIYing a printer.

I spent so much time on my fully-modified Ender 5 and it still doesn't print nearly as well or fast as a cheapo A1 Mini.

The version A) is a big issue actually, thanks to the Hoskins effect.

That means that if the immune system is trained for a slightly wrong type of pathogen, it might have a worse immune response to the actual pathogen at hand than if it wasn't trained at all.

So if that viral protein would mutate a bit, so that it's still recognized as viral protein by the immune system, it might cause the immune response to the actual virus to be worse instead of improving it.

Die EVP ist deiner Meinung nach nicht rechts?

https://de.wikipedia.org/wiki/Europawahl_2024

Es gibt 720 Sitze, die Mehrheit hat man also ab über 320. EVP + PfE + EKR + ESN haben zusammen 375 Sitze.

Die Rechten haben gerade jetzt im Moment eine Mehrheit im Europaparlamant.

The reason why I thought about harmful mutations in this context is because this strain of yeast has some kind of property that activates the immune system, otherwise the whole concept wouldn't work.

That's not something regular yeast does, so for regular yeast to evolve something like that, that's a major step in evolution that doesn't happen quickly.

But modifying the immune system activating payload is much less difficult.

Due to the Hoskins effect, it's possible that an immune system trained for a "somewhat wrong" pathogen can perform worse than one that hasn't seen that kind of pathogen at all before. So if the payload of the yeast mutates, it can "mistrain" the immune system so that it then performs worse on the real-life pathogen.

The difficulty I see here is that it took the yeast not very long to mutate a beneficial effect, but it could just as quickly mutate away from that and even mutate something harmful.

The biggest cost factor for classical pharma is QA. Both in the form of certifications before release and in the form of regular QA during production.

So skipping QA can of course bring the cost down massively, but with the cost of making a potentially very dangerous product.

Peasant in wicked cosplay? That would be a fun NPC.

 

There's really no limit on what can be made to sound good with enough time and skill.

 

First, so I'm not misunderstood: Science does of course exist and it is not religion. But:

  • Not all published science is, in fact, science. The Replication Crisis is a real problem, meaning that a significant portion of published science is actually incorrect.
  • Only a very tiny portion of the population reads scientific papers and has the ability to understand them. That includes scientists and other well-educated people who don't have any expertise on the specific field. Being a renown physicist doesn't mean you know anything about psychology.
  • Scientific papers are filtered through science journalists who might or might not have any expertise in the field and might or might not understand the papers they write about. They then publish what they understood in a more accessible format (e.g. popular science magazines).
  • This is then read by minimum wage journalists with no understanding of any of the science, and they publish their misunderstandings in newspapers and other non-scientific publications.
  • This is then read by the general public who usually lack the skills and/or the resources to fact-check anything at all.
  • These members of the general public then take what they understood as fact and base their world view on it. At this point it hardly matters whether their source of incorrect information is the stack of Chinese whispers I wrote about above, or if it's just straight-up made up by some religious leader.

There's thousands of little (or big) misunderstandings in non-science that people believe and have faith in, that forms people's world views and even their political views. And people often defend their misconceptions, like they would defend some religious views.

(Again, just to make sure I'm not misunderstood: I am no exception to this either. I got my field where I have a lot of knowledge, but for most fields I blindly trust some experts, because I have no way to verify stuff. I, too, for example, put my faith in doctors to heal my illnesses, even though I have no way to verify whether anything they say is true or not.)

 

Well, not exactly modern social media, but very similar mechanics. His dad wrote a book with him as a main character, and he got bullied for it and ended up resenting his parents and hating Winnie the Pooh.

And in keeping with modern-day influencer parents: He actually never really had a lot of a relationship with his parents to begin with. He was raised by a nanny and then put into a boarding school, and only had very little contact with his parents. Later in life, he only sporadically visited his parents, never returned to his childhood home (which was the books were based on) and after his dad died, he completely dropped contact with his mother.

 

I guess, the limit doesn't apply for every country, but at least in Europe it's quite common.

Using an exoskeletton would also get around the speed limit for the pedal assist.

 

Take that (not) Einstein!

 

Ich frag mich echt wie blöd man sein kann. Sowas passiert hier echt grad im Zweiwochentakt.

 

If a country needs to overly emphasise an ideal, that's usually because that ideal doesn't apply in that country ("Land of the free", "Democratic people's republic of ...").

If a person needs to subscribe to patriotism, it's usually because they have never accomplished anything better in their life than being born in a specific place.

 

Eigentlich versuchen sie nur junge Muslimas zu nerven, aber beim letzten Anlauf in 2020 haben sie aufgrund des verfassungsgemäßen Verbots der religiösen Diskriminierung kurzfristig alles religiösen Kopfbedeckungen an Volkschulen verboten.

Hat blöderweise mehr Juden und Sikhs betroffen als Muslimas.

 
 

Disclaimer: Someone in the comments pointed out that this affects Nvidia only. I don't have AMD, so I can't verify if that's correct, but likely this is only for fellow sufferers of the Green Nightmare.

I had this issue for months. Randomly, the performance for games would be abysmal (I'm talking 5 FPS in 10yo indie 3D titles). Then it would randomly work again for a few days or weeks until it would become terrible again.

Turns out, the reason for that was that flatpak appears to cause trouble when the system GPU driver is updated, but flatpak update isn't run. So when I did dnf update (and it updated the Nvidia driver) without running flatpak update afterwards, the performance would suck, until something (or I) ran flatpak update again.

So if the performance in games launched through a flatpak version of a launcher like heroic sucks, run flatpak update.

And if that doesn't work, run

flatpak install flathub org.freedesktop.Platform.GL.nvidia-575-64-05 org.freedesktop.Platform.GL32.nvidia-575-64-05

(Replace the version with your Nvidia driver version, and in case of AMD, google whatever the appropriate way is to install the drivers for flatpak.)
