Extended outage, yes. I moved house. That wasn’t itself the problem: the problem was that the machine which runs this blog decided after the move that it didn’t want to run for more than a few hours at a time without panicing randomly.
After replacing the mouse (no, really, the USB-serial interface it was plugged into seemed to be sporadically disappearing from view), hoovering out the inside of the case, reseating all the cards, and various other forms of voodoo, it seems to have been made stable by a couple of BIOS tweaks I found on overclocking forums: upping the northbridge voltage and dram voltage by 0.1V. Apparently this is a common problem on the Asus P5Q-EM when it has all four ram slots full.
And no, I’m not overclocking it.
Anyway, I have a stable (so far) system again and blogging service will resume soon. First up: it must be late last year that I started playing with Ruby, so it must be about time for the 6-month review.
Broke again, now back again

If you have a tech-friendly ISP (like mine ) your DSL service might not only have a static IP address (one that doesn’t change each time you reconnect) but several of them. In my case, 8 (five usable).
If you have a Draytek Vigor router, you can configure it to know about these using the 2nd subnet support – this is what I did before I moved, with the 2600 I had at the time
If you have the specific Draytek Vigor 2700 model that I have (and I don’t know how wide a problem this is) you may attempt to follow these instructions but find that the configuration options for second subnet are missing. The option for DHCP relay agent is missing too. I tried a bunch of stuff including factory reset, firmware upgrade, and “phone a friend” to resolve this before eventually grasping the nettle and fiddling with firebug and HTML “view source”
HIDE_LAN_GEN_DHCPRELAY) are, on my router, set to
true. So, login to the router, pull up the firebug console, enter
and then choose “This frame”, “Reload” from the rightclick menu in the main frame, and you should find they magically reappear and you can configure them appropriately. This will almost certainly take you less time to do than it did me to work out.
