  • Running Systemd within a Docker image

    NOTE: This is not for general purpose use – CAP_SYS_ADMIN grants the container a large number of dangerous privileges – this should be used only by a sysadmin (Ops) – not a developer – for the purpose of containerizing infrastructure. Some of my insights gained on running systemd within docker – I’m aware the general […]

  • Fun with VPS’s – brad-x moves into the cloud

    In an effort to do some finance management I’ve switched from a dedicated server at $132/month USD to a VPS hosted by Burst.NETĀ for the eminently reasonable sum of $10/month. For this price I get 50GB of disk space, 1GB of RAM and 1.5GHz of allocated CPU clock – more than I’ll need! I’m also working […]

  • Practically Replacing Microsoft Exchange Server – A 3 Part Series – 3 of 3 – Kerio Mailserver

    Kerio MailServer 6.5 – The Exchange Killer Kerio MailServer, like Zimbra, has until only recently been an ‘almost but not quite’ Exchange alternative.

Zimbra’s latest version, which has only been in the wild for a few months, is different.

  • Linux for everyone? Not so.

    Great review here from Walt Mossberg of the Wall Street Journal. An unbiased look at some of the things techies don’t mind doing, but your average user would find utterly stifling. Check this out.

  • Well, he might have said it…

    “We choose Gentoo… not because it is easy, but because it is hard, because that goal will serve to measure and organize the best of our energies and skillz, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and because of the pJE4R.” — John F. Kennedy

  • Home movies with Linux: Not Ready for Prime-Time

    UPDATE: I had originally titled this article “Home movies with Linux: Beginning the exploration (of things Linux can’t do)”, but have since changed the title to be a bit more fair. It is a given that Linux isn’t suited to certain tasks, but rather than show these things up as embarrassing shortcomings I’d much prefer […]
