Task Manager shows vmmem consuming several gigabytes of RAM, even when you're not actively using WSL. Here's how to actually diagnose what's holding that memory, and how to cap it properly.
Before WSL let Windows run real Linux binaries, Microsoft tried and abandoned a different compatibility project entirely. Here's the actual path from that cancellation to today's tightly-integrated WSL2.
WSL2 doesn't borrow a distro's kernel — Microsoft maintains its own fork, patched specifically for the virtualized environment WSL2 runs in, and ships it independently of both Windows and any Linux distro's own kernel.
Before WSL let Windows run real Linux binaries, Microsoft was building a bridge to run Android apps on Windows 10 Mobile instead. That project was shelved in February 2016 — clearing the way for what came next.
Because remediation worked, January 1, 2000 passed quietly, and some people concluded the whole thing had been overblown from the start. The systems that skipped the fix tell a very different story.
These two terms get used interchangeably in casual conversation constantly. One is a physical and logical network; the other is a specific application built on top of it, invented years later by a specific person.
The Apple I and II are often credited as the birth of personal computing. A different machine, from a company most people have never heard of, beat them to market by more than a year.
Ray Tomlinson is credited as email's inventor, and rightly so for one specific, real breakthrough — but the popular version of the story usually skips over the messaging system that already existed before he touched it.
Napster gets credited as the technology that started internet file sharing. BBSes, Usenet, FTP, and IRC were all moving files between strangers years — in some cases over a decade — before Napster's 1999 launch.
Popular legend treats the Alamogordo landfill as an E.T.-specific burial ground. The 2014 excavation found 59 different game titles among the recovered cartridges — a much broader inventory clearance than the popular story suggests.
