🤔 So, you’ve always wondered why your computer needs #RAM when it has a hard drive? 😴 Apparently, the answer is buried somewhere in this endless lecture on Virtual Memory, which is essentially the “intro to intro” on why your PC isn’t a potato. 📚✨ Spoiler alert: RAM is faster than a hard drive, and CPUs are faster than both, who knew! 🚀💾

The April issue has been released! This month we take a look at virtual memory in Linux.

Hot take: Underspeccing on RAM is a deliberate ploy by hardware manufacturers to wear out other hardware more rapidly.
High virtual memory use degrades storage drives, and overworks CPUs. This all increases heat overall, and causes unnecessary systemwide stress.
I guarantee this is part of planned obsolescence.
I had 32gb of RAM in my desktop in 2011. They're still releasing home and office computers with 4gb of RAM in 2023... an era where cell phones often come with 16gb of RAM.
Every single computer with 16gb or less that I've encountered has so many hard faults that it freezes randomly when there's almost no CPU use.
Do yourself a favour if you like your computer and buy some more RAM for it.

someone who is good at virtual memory please help me budget this. my #Meilisearch is getting allocation errors

A difficult podcast episode. Gil Roth of the Virtual Memory podcast turned up on Saturday to interview Michael Denneny, 80 year old gay author and editor, to talk about his book "Christopher Street: Life, Sex and Death After Stonewall." Only to find that Michael had died and had been lying undiscovered until Gil's arrival. Instead of an interview we get a monologue, about the experience, the shock, about what is lost. #podcast #VirtualMemory #death #grief

The second part of Asus #EeePC Android-x86 4.0.4 experiments: trying to "trick" Android into using a form of #virtualmemory on Alpine Linux in order to use modern Firefox by means of a VNC "Inception", exploring a huge treasure trove of Java midlets with unexpected finds, including Lisp and #J2ME SDK Mobile, a. jar to build Java programs ON your phone, and finally recommending settling into a peaceful, simple life with a very retro operating system: https://www.youtube.com/watch?v=931Y5FRj-xE
In my quest to understand the vm subsystem reading the brick that is Gorman's Understanding the #Linux #VirtualMemory Manager. Hope it is still semi-relevant to today's kernel. Getting closer and closer to finally figuring out *how* one might write exmap, let alone actually doing it
This keeps tripping up new developers (if they ever become aware of it at all):
