I still find slashdot entertaining, due to the humour, the culture, etc... I just don't learn much from it any more. Back in the early days, there was always something new to be learned about technology, open source, computer security. I think both slashdot and I have evolved. I simply know more now, and slashdot might have gone down a the drain a little bit. However, I say that with the knowledge that other forums never even had the level of conversation one gets here, even now.
Picture, instead of Clippy, we could have Microsoft Creeper.
Sure, it's not the most efficient codebase, but on a modern machine with power to spare, it's rather fine. Now, I have run it on a rather high end Core2Duo. That's less fun.
Most teenagers I know wouldn't touch old computers.
These days you can easily find Core2Duo and AMD64 class machines in dumpters, and from what I see, nobody wants them. I used to refurbish them for those who wanted and I ended up with a huge pile of decent machines looking for a good home. No takers. I trashed them all.
I guess they have old PC-s.
I have a few machines, all of them run exclusively Linux, all of them can (and have) run Minecraft. Let's see, my desktop replacement is a i7-2630QM with 16GB RAM, my Ultrabook is i5-3357U with 4GB RAM and my desktop is a A8-3850 with 16GB RAM. (I'm excluding my servers here, as they have different use-cases.) Are these machines "old" now? Sure, they aren't brand-new, but I'd say they're all adequate. Surely not enough to run Crysis, but they're no slouches.
OpenBSD truly adheres to "KISS", especially regarding simple configuration files. Exactly of what systemd isn't. It may have (and I'm still not convinced) nice features, but for my uses what is presently being used suffices, both on Linux and especially on OpenBSD.
