    A few days ago, someone posted a link to a story in The Atlantic, referring to a leaked NSA document that showed that the agency had lied. The particular article is weak and irrelevant – one of a stream of similar articles that follow on the heels of each new Snowdon revelation.

  • Why spammers send “from” your email address

    Someone asked me recently why spammers often use other people’s addresses in the “From:” field of their spams. They asked “what’s the payoff for the spammer in doing that?” Here’s the answer.

  • Mikrotik troubleshooting case study

    Just for the fun of it, here’s a a case study in troubleshooting. Actually it’s a case study in stupidity too, since I should have figured this out without all the troubleshooting. Anyway, just as an exercise…

  • Mikrotik plus phone dongle = instant hotspot

    I attended the Sapphire Coast StartUp Camp this weekend. At one point in the leadup to it, it seemed the venue would have no Internet access, so I suggested setting up a MikroTik router with a GSM phone dongle to provide wifii/LAN and Internet connectivity.

So we went home and made one ourselves! It only took about fifteen minutes.

    Recently, I was directed to an article in the Sydney Morning Herald of 2 May 2013, touting in uncritical fashion the supposed benefits of VDSL – Vectoring DSL.

  • Digital tear-gas

    A discussion started on a network operators list I frequent, about a case where an apparently innocent party, Melbourne Free University, had had its website blocked. Aside from a terse “yes it’s blocked” from one provider concerned, no further information was forthcoming. Here’s one report about it. (more…)
