Fun with ANALYZE TABLE

MySQL has been naughty for me lately. First, I ran into a neat little issue on FreshBooks’ production servers last week involving the table cache and an O(n) algorithm for selecting a table to close. I wrote up a little explanation over on the FreshBooks blog that you might find interesting if you find any […]

Printer fun

I spent much of the afternoon yesterday on the phone with Dell, debugging a confused printer. We moved the printer across the room, and following that it wouldn’t print; it’d just sit there at “Printing…”, and the client print progress thing would stay at 0%… until you disconnected the network cable. Then it’d print whatever […]

Fun with DHCP

I rolled out a new firewall/DNS server/DHCP server at FreshBooks today. Went well except for one problem: occasionally people would lose DNS resolution. Well, that’s not good. Checking out their machines showed that their DNS server addresses were being changed to an address on the wrong subnet, and their domain being changed to “mshome.net”. That […]

Rogers Portable Internet

At FreshBooks, Internet access is pretty critical to day-to-day operations. In fact, there’s basically nothing we do that doesn’t require it. But we’re not big enough and don’t transfer enough to bother with, say, an E10 or multiple T1s. So we’re on Bell business ADSL, which with a bit of traffic shaping is fast enough. […]

Yay, I’ve got DSL now…

Yay, I’ve got DSL now at the new apartment. I ended up going with Teksavvy, which was a bit of a roller coaster to order — they mistranscribed my credit card number, phone number, and mailed my DSL modem to “First Books”, and then the Bell tech showed up today at the wrong house number, […]

SAGE or LOPSA?

I know I’ve got some professional sysadmins reading this, so: I seem to have slept through the period around 2004 to 2006 where USENIX nearly got rid of SAGE, and then didn’t, and then some people who wanted SAGE to be rid of USENIX formed LOPSA, and so on. But I was all set to […]

Goings-on

This morning’s double take: Last night before I left the office, I sent mail to a few coworkers and a few Toronto friends asking for recommendations for DSL and VOIP providers. This morning I had recommendations from a bunch of people I knew, and one person I didn’t. Why one person I didn’t? Because one […]

Toronto update

Well, I suppose I’m due a post, eh? It’s been a whirlwind, so I’ll quickly skim over everything. I’m in Toronto! I got here on Saturday morning with Candice. We spent the weekend seeing apartments — 6 or 8 on Saturday, and then two on Sunday, staying at the Holiday Inn on Bloor at St. […]
