This week: lots more reading!

• Michael Lucas describes an extra layer of protection for when you can’t force public key usage on every SSH user.
• Cool, but obscure Unix tools (via)  The screenshots are all from a Mac… How many of the 24 tools listed are in pkgsrc/pkgsrc-wip?   Almost all of them.  (tpp sounds entertaining.)
• NYCBUG, in addition to having a really fun convention, has been regularly posting audio of the presentations they host.  The most recent is “William Baxter’s NYCBUG presentation on The Unix Method of Development Management”.   See the BSD Events tweet for the download.
• What Ubuntu means.  (via)
• Here’s a nice explanation of Intel’s new Tri-Gate design and with it, an incidental explanation of the processor market.
• This ycombinator post about Hammer2 work has an in-depth comment from Venkatesh Srinivas about DragonFly’s network setup, memory allocator, and token use.  (Ignore the trolling in other comments.)
• Michael Lucas’s next No Starch Press book is Absolute OpenBSD, second edition.
• Pictures and video are starting to show up from the just-passed BSDCan 2011. (via this and also thesjg on EFNet #dragonflybsd)
• My first experience of The Internet was very similar to this.  It should be bizarrely unfamiliar to anyone under 20 or so.  (via)  Get this: I typed ‘exit’ instead of just closing the browser window when I was done messing with it, because some habits cannot be broken.
