I think I’m finally catching up on the backlog.

• Unix: Flexibly moving files with lftp.  I usually copy and paste a shell script together.
• BANCStar source code.  In that sort of environment, there’s no good or bad code.  It has moved beyond such considerations.  (via)
• The Lenna Story.  About the 1972 Playboy centerfold image used to test image compression.  I mentioned it once before in passing.  (via)
• If you find regular expressions difficult, putting another layer of expression on top doesn’t help.  (via)
• How not to check the validity of an email address.  I had a similar experience at an old job in 1999, where a coworker set a site’s main page to get all news stories and then showed the 10 most recent.  This started to really slow things down when we reached over 5,000 stories…  (via)
• Achieving Rapid Response Times in Large Online Services.  A PDF of slides.  (via)
• It’s described as “the best programming fonts“, but it’s really the most popular monospaced typefaces.  Who cares about correct language – it has visual examples. (via)
• Phone keypads could have been very different.  (via)
• Sudo Mastery’s first draft is complete.  You can buy it now and get updates as it gets polished.
• Have yourself a keysigning party.  GPG is complicated.  I know there’s reasons, but still, this is the sort of thing that would be better with as little barrier to entry as possible.
• The Internet, via Commodore64 and Neuromancer.
