Since 2003 I have printed every single interesting web site I've ever bothered to read - and some I haven't - to PDF file. Instead of Ctrl-D to bookmark, I Ctrl-P to print-to-pdf.

I keep these PDF files and use them where most people would have bookmarks.

The advantage is that I have an offline cache of materials (60,000+ files), a carefully curated list of stuff I like (or can be bothered to think about long enough to decide I might need it in the future), and endless amounts of material to pdfgrep for further drilling.

This has given me quite an edge, time and again, because while others are struggling to find that one bookmark that has the article they kinda remember reading once a few years back, I've already found it, gone to the new site, seen the state of the art as it progressed in the time since my visit, and so on.

I believe this has given me a 'second brain'. There is no greater joy than to drop into this directory and do an "ls -alF | grep <some search term>" and find every single page I've read since 2003 on that particular topic, still in the original form I remember - and then to re-visit the page and get the updates.

I have a lot of HN articles saved this way - as well as the HN comments too, and this has also served as a second harmonic to my general knowledge, ready and easily accessible should I need it.

Try this trick, it really kicks ass!
