The problem with the rpi is it's basically a gpu with a cpu bolted on. All the power is in the gpu.

Isn't it true for all the computers nowadays?

Depends on what abstraction level we examine. They are too cumbersome to program so aren't used much outisde games. High theoretical compute bandwidth, but end-to-end looking at application-delivered compute abilities, low expressive power and flexibility to realize our programs. Which is after all the point of programmable computers in the end.

I bought a Raspberry Pi to use with my 3d printer. I left it on all the time and that was a mistake. It killed two SD cards over a period of less than a year before I figured out that the constant writing to system logs was responsible.

I bought a third card and now I turn it off every time I’m done with it.

Why not just disable logging? Have you ever needed the logs for anything?

My son currently does and has for about a year. I also have for short periods as computers were "in the shop." He's used a couple different pis with varying success. At least 4 GB of RAM is a must. The distro you run also matters a great deal. The Pi4 with 8 GB is very usable as a main computer. I'm a Fedora person normally but for the Pi Raspbian is always my choice because it is so well optimized for low memory dev…

This is fascinating to me. 4GB of memory is not enough, on an OS "optimized for low memory devices"? What crazy world do we live in?

I remember browsing the web with 64 mb of RAM, upgraded from 16 MB, and a 100 MHz CPU.

I'm not saying you're wrong in any sense. I'm just marveling at the state of memory use in computing.

Earlier quoted context omitted.

They really don't though, they could do it just fine in 1995. Browsers have bloated into crazy complex machines though that do way more than rendering some text and graphics. The simple rendering is not why browsers are slow on RPis.

Enough of such comments. Obviously you have never worked much in the front end or the web user experience, and don't understand the complexity or the difficulty of such technologies. Anyone saying "things were fine in 1995" is ignoring how non-interactive, non-intuitive how web pages were, and how much more pleasant it is to look at a web page and get the information today. It is true that some web pages are using un…

You say, commenting on a website explicitly designed to be minimalist which would be perfectly comfortable running on a 1995 level hardware.

Most of the web I visit doesn’t need to be interactive all that much and the interactivity that is added gets in the way more than it helps anything. We’re just exchanging pictures and text here. The bits where people are writing applications on the web really get in the way of experiences where people are just exchanging content.

I didn’t know the logging was responsible until after I burned out two. When the first SD card died, I assumed I had a faulty one. When the second one died, I looked for a cause.

The logs were useful initially to help me determine that the Pi was crashing because the power supply wasn’t stable enough.

Mostly though, what I really want is an appliance that I plug in and never have to worry about it again. I understand that a Raspberry Pi running Linux isn’t that, but I was an optimist. Now I just turn it off.

Tried, but there is a lot of caching of processes in windows to make the experience faster and smoother.

Most websites are heavy and what I mean by that is they have a lot of javascript, so its not just downloading stuff, its then having to run that stuff which is an overhead the rpi cant quite handle. I dont know if the javascript executing on the rpi can be optimised but I suspect the javascript is better optimised for Intels and AMD's.

The mouse is too twitchy, it needs a bit of damping to make it smooth moving over the desktop and hovering over buttons. I suspect there is a bit of AI in windows which predicts when someone clicks a mouse button that they actually wanted to click the mouse button over the screen button, ie something to improve the accuracy and experience of windows.

Could you elaborate on which kind of situations you think you have seen this in? I really don't think I've seen this happen.

I have no problem browsing the web on a thinkpad laptop with 4gb of RAM. I’ve always suspected that the issue with Pis is that they fall over when they try to write to swap. The SD card can’t handle it. The RAM isn’t really the limitation, it’s using an SD card for swap. Can anyone confirm?
