ZDNet ☛ How much RAM does your Linux PC need in 2025? Here's my ultimate sweet spot
I'm not going to start this with a "back in the day" because it's too easy and obvious. Besides, it's time to live in the now, and today's rules and needs are not the same as they were 10, 20, or 30 years ago.
Modern Linux is powerful, flexible, stable, and secure. With the exception of some of the more lightweight Linux distributions, it's also far more resource-dependent (just like all modern operating systems).
Consider this: The minimum system requirements for Ubuntu Desktop today include just 4GB of RAM. I've run Ubuntu on a virtual machine with only 3GB of RAM. Although those Ubuntu virtual machines are used only for testing purposes, the 3GB of RAM does pretty well. But I would never suggest you should get by with such a small amount.

ZDNet ☛ How to manage your Linux firewall the easy way - without touching the terminal
A firewall is often the heart and soul of desktop security.
With a firewall, you can block or allow traffic in and/or out of your computer. Of course, it's the incoming traffic that you need to be most concerned about. You don't want some ne'er-do-well to see port 25 open on your PC and use it as a way to get into your system and do bad things. To that end, your firewall is the way you shut those ports down.
Back in the old days, the Linux firewall was a very complicated piece of the puzzle. To use a Linux firewall in those early days, you had to learn the very complicated iptables system. Suffice it to say, that was not easy. I always had to keep copious notes on how to use iptables, and sometimes it even stumped me.
Fortunately, as Linux evolved, firewalls became considerably easier. With the likes of UFW (Uncommon Firewall) and firewalld, there's no reason to even bother with iptables on the desktop Both of those modern takes on the firewall (which actually act as intermediaries for iptables) offer simplified command-line usage.
Oh, wait... did I just say "command-line" like it's a good thing? Let me walk that back a bit. Both of those modern takes on the firewall also have GUI apps that make using them even easier.
