More from the Australian Computer Museum: https://acms.org.au/
This time, it's Australia's favourite '80s home computer, the MicroBee.

Everyone remembers the MicroBee. But does anyone remember the Hartley Computer?
This is the often forgotten '80s Australian microcomputer from Queensland.

Forget AI, the new buzzword in computing is "quantum".
Remember to update you CVs!

Maybe we need to update #RTFM. Actual manuals are rare beasts these days. You’re more likely to find the information you need online, whether it’s in the form of PDF datasheets, forum posts or Git gists.
It should really be RTFAI, in which the AI isn’t what you think but stands for ‘Available Information’. But that’s a bit of a mouthful, so perhaps just RTFI. Or we could just say ‘Read’, followed (if you feel strongly about it) by FFS. RFFS?

If you love the internet or computers and haven't watched this video from @geerlingguy you should!
"...
We all have this shared passion for technology, but coming together, it's like the anti-AI.
...
There wasn't really any social media, no screen names.
We shared the things that we loved.
I really hope more people can see the benefits of retro computing." - Jeff Geerling

Yesterday I visited the computer games museum 🕹🎮👾 in Berlin. It was a flashback in so many ways; I really enjoyed it.✨️ The highlight was my very first computer, with which I learned my very first programming language, #gwbasic. The Schneider CPC with its quite exotic 3-inch floppy disk drive. 💾
Hands up, who knows GW-BASIC and maybe even used it?

Reminder: If you're on #Windows10, and you can't upgrade to #Windows11, and you either
A: Only really use a web browser or
B: Have open source alternatives to software that you use and are willing to try them out,
You do not need to junk your #computer and upgrade to Windows 11! Instead you could try #Linux!
My recommendations would be either #LinuxMint or #PopOS as those are generally regarded to be great distros for people new to Linux.
Before you decide to dive in and commit to Linux, some suggestions.
1: If you have an external hard drive or are willing to buy one, please put any and all important stuff you do not want lost on that drive. Cloud could work but I think best practice is to always have local copies.
And if you do install Linux, just in case, keep your external hard drive disconnected from your computer so that you don't accidentally overwrite it. It's easy not to overwrite your backup files but I would consider it best practices.
2: You don't necessarily have to commit to Linux the second you read this post. I do think you should try before you buy, as it were. Most mainstream versions of Linux let you live boot the distro before you actually install it on your computer, that way you can test things out and get an idea of what you like and don't like, and you don't have to figure out how to make a virtual machine to do it. (I recommend using BalenaEtcher or Ventoy to make your liveboot USB and you should be able to find plenty of tutorials for both.)
3: If you DO decide to install Linux, but you want a desktop environment that feels familiar in order to help you warm up to it, you can either try Cinnamon, or Plasma. A desktop environment is a graphical way to interact with your computer. Think the start bar and menu in Windows. Plasma and Cinnamon have a similar look and feel to Windows. But that doesn't mean Gnome is by any means bad.
After, you've tried it and you're sure you could see yourself using it, then you can decide whether or not you want to install it.
Linux is at a point where you can easily game on it. The only real concern on that end tends to be multiplayer and isn't really an issue of Linux itself so much as game devs.
There's lots of great open source alternatives to a number of apps. In my case I mainly use art and office software. I have not used proprietary art software in years. What's more, you don't need Linux to try these software out as pretty much all of it is available on Windows for you to try!
Installing Linux itself is as easy as installing Windows software, at least the stuff where you have to download an executable, run it, and hit next a bunch. Just read things carefully and it's a pretty painless process.
And if you heard that Linux requires you to use command line, I assure you, you probably won't need to use it any more than you did in Windows. I mainly use it to run OS updates but that's just the way I prefer to do it. This is stuff that can be done through GUIs these days.
Either way, depending on your needs, you can get years of use out of your computer that you wouldn't if you junked it and bought a Windows 11.
And even if you DO get a Windows 11, maybe installing Linux on your current PC will let you find another use for it
