A decade with Ubuntu and I get why it’s free. I have disastrous performance issues with it, for reasons that people usually respond, “oh well that’s not Ubuntu’s fault…” but that isn’t a great excuse as users do not care (unless you aren’t intending to attract general users). Most of the issue is that I have to fight with nvidia video drivers every month or two. Something happens and they stop operating and it grinds…

"Potemkin UI" Thats a good description for many linux GUIs. They look like they can get the job done, but to really get the job done, you have to use what the developers of said UI likely themself use - the terminal.

A friend used the term when I said, “I used Additional Drivers to update to the latest recommended driver and it bricked my computer.” He said never to use that UI and to do it via a terminal. The terminal approach worked effortlessly and in half the time, once I Un-bricked my laptop.

It feels like a lot of the UIs in Ubuntu are there just so they can claim it’s an OS that can take over for Windows or Mac.

This is one of the primary resaons I ditched Windows for Macos. The multitasking on Windows is ridiculously bad. Also, applications that freeze and can't be killed/restarted are simply part of life on Windows. Add to all that, Window slows down over time - again, the periodic reformat and rebuild is part of life on Windows. After I switched to Mac I didn't need to rebuild the operating system essentially ever. Also,…

This is a very outdated take on windows. I’m not sure what “multitasking is bad” means, but I do a heck of a lot of multitasking on windows every day with resource intensive developer tools with no problem, and have been doing so for over a decade. Apps can be killed via task manager without doing anything special. You might run into an occasional rare bug where explorer freezes so you can’t open task manager, but I…

Try to sort by name in task manager and wait as it locks up for seconds.

It's frustrating that efficiency and being a good desktop citizen is such an afterthought for most browsers. Support for all the fancy web features imaginable is isn't worth much to me if means keeping my system pegged and destroying its battery life.

Afaik browsers are highly efficient and a lot of work goes into optimization. On the other hand, they're expected to run arbitrary code (JavaScript, Web Assembly) which can do all matter of terrible things. A couple years ago, it used to be Gmail/Google Voice websites would take nearly 1GB of RAM alone per tab and crash if you left them running a few days. A website could just run in a tight loop and the browser has…

things have improved a lot over time. I have one project involving json arrays that grew way out of hand. Sort of panicing about the need for a fast 80% rewrite while not having 10% time I tested a good number of devices. Crappy androids and low end iphones deal with the many thousands of objects incredibly fast. I still think its wrong I just have nothing to show for it.

ff a decade ago would just randomly die on me within 2 days.

I just did and it was instantaneous. How many tasks are you running?

I've since switched to using AMD graphics on my linux machine. Been running from a RX-580->5700XT->6800XT. It's been pretty good while using Fedora.

I've had lots of luck and fun with Fedora, AMD cards and GPU passthrough to VMs. Very stable and fast.

With regard to latency sensitivity, with so many cores available, a single core could be dedicated to processing mouse input. Of course, if there's a lock in the way that's held, that's still a problem.

For a modern system like Wayland or WDM, the display compositor gets rectangles of pixels from the applications, copies those into a big rectangle it sends to the rasterizer. Just before it does that, it draws on a mouse cursor. It also has to communicate with the applications about what image to draw so you have to deal with multiple threads no matter what. (Unless you go back to the late 8-bit era where the cursor…

sure, no problem, negotiate with the application, but also act as a responsible shepherd of the desktop, if some timeout is exceeded draw the "application is busy" cursor.

this already happens, just after some laughably long chain of unprocessed input events

Frameworks are nice in theory but they still have a long way to go when it comes to heat, fan noise, and battery life based on what I've seen owners of them say.

Yeah, they are Intel in the end, which is tough on battery and heat. I hope that will get better if they switch to AMD.

This is the biggest reason that I won’t get a Framework today. Give me a Ryzen with 8+ cores, 32GB DDR5, hopefully two m.2 slots, a full-size HDMI and USB-A port(s), 99wh battery because of TSA security theater, dedicated graphics, and some real heat sinks that can handle 200w+ so it doesn’t have to run the fans constantly or cook the touchpad. A 4:3 OLED with at least 4K resolution and 120hz refresh would be perfect on top. Ooh, and a rigid chassis that doesn’t flex like a noodle, and no RGB / gAmER tacky plastic junk all over. It’s sad that a package like this is very rare.

What are you talking about, it's not rare at all. My desktop is exactly like that.

It's probably not as good as an M1, but it'll last you more than two years I don't disagree with the other positive aspects of the Framework, but my goodness -- where are you getting this idea that a Mac lasts only two years? 6+ years is the norm for me on Macs.

my macs absolutely start to degrade after about 18 months, and I try to keep them limping along for a few more months. I think it’s usually the battery crapping out that causes everything else to sort of overheat and suck

Well, mine admittedly are used primarily for duty so I suppose mine live a rather cushy life - particularly my batteries.

However, I don't think I know how decreased battery life would lead to overheating?

Certainly, dust inside the machine will lead to overheating (or at least, more fan activity) over time. Coats the heat sinks, etc. Perhaps that's it?

Blink and Gecko don’t fare as well as WebKit does when it comes to efficiency which would suggest they’re making tradeoffs favoring things other than battery life.
