  • April 2014 Reading

    Bernays was Freud’s nephew and one of the earliest developers of the Public Relations industry as we now know it. The book is, of course, disturbing but it is also eerily prescient talking about thought leaders being able to use their influence to ch

  • Quick tip: Postfix operators in GHCi

    The other day I wanted to work out what 52 factorial was. I’d beeen to a pub quiz the night before. What can I say? It is pretty easy to make the factorial function in Haskell. Something ike this usually suffices. fac :: Integer -> Integerfac n = product [1..n] I wanted to be

  • Tip: Change or add passphrase on existing SSH keys

    Today I needed to add a passphrase to an ssh key. The key had previously been used for automated batch processing work in cronjobs, and thus didn't have a passphrase set — a bit of a security no-no. A quick scan of the ssh-keygen manpage led me to the -p flag, which updates or creates a pas

  • SVG logo: half the size and better quality

    Its not that I’m a performance fanatic. But a fairly big part of the page weight on my new site is made up of the top logo. Which, until yesterday, was a jpg. Previously it had always been a png which seemed sharper to my eye. But it took 50 kilobytes, although it is cacheable that is still a

  • January 2014 Reading

    Baffling guide to a paralell but familiar world, told through surrealistic short passages that are sort of semi-coherent. It is like the world that you experience in a half dream. There’s no obvious narrative; it reads
