I had a sudden buildup of things to link to.  It’s three items, but there’s enough info here to eat a few hours…

• Flash Destroyer: (destroying hardware, not like what Apple’s trying) found via the howling void, which of course has lots of complaints about technical inaccuracy.  Still, interesting to contrast this with swapcache usage.  The Bus Pirate on that site also sounds interesting.
• Handling multiple SSH keys in your SSH config: talks about one issue that came out of a larger IBM developerWorks UNIX tips article which is part of a larger series.  I may have linked to parts of it before; it’s firmly packed with usefulness.  Seriously, go read.
• Dru Lavigne linked to this article about the future of software development, and I agree with her: it’s a good prediction of the very near future.
