It’s been some years since I decided to keep whatever I use online – at least the reference content – locally on my machine. In a normal country you’d ask why? And most of the time you’d be right. There aren’t many convincing reasons to localize everything.
But – and this is a really big but – in countries like Iran, where we had 3 internet blackouts in a single year, you’d better think twice.
I call it “offlinification.” The tool I use most is Kiwix (kiwix.org). It lets you download Wikipedia, medical guides, documentation, and more – and browse them completely offline, no internet required. Full Wikipedia fits on a cheap USB drive.
