China datacenter by the (wall-clock) numbers

This is part an homage to John O’Duinn and in part to win a wager with someone over how quickly I could get a datacenter up. Twelve hours was what I said I could get it done in. The actual start time may be up for debate. I started my timer from the moment the… Read more

How do you rack 50 Mac Minis and use only one power cord?

As mentioned during the Monday meetings, we’ll be deploying a farm of Mac Minis to augment our Firefox performance cluster. Here’s the dilemma – 50 power bricks converting AC to DC is a waste of heat and space (and my time managing Apple’s 6′ power cables) and makes me having to find a PDU with… Read more

MySQL Cluster, is it worth it?

I’ve been trying to figure out if a MySQL Cluster would make sense in our environment and if it’s worth the complexity. I think so but I can’t find enough information online to answer some nagging questions.

Today was filled with a long, exhausting work day interrupted by lunch at a nearby seafood place Li and everyone at the office took us to. I think the feeling was that this place was average but to my untrained Chinese tastes, the food sure was good. We met Mi Jai after breakfast (and after… Read more

China, day one

In China now, after a 12+ hour flight from San Francisco.  Got in about 4-5 hours ago (I’m all screwed up on time right now). It’s overcast and muggy and reminds me of Chicago summers.  Amazingly like Chicago actually except that I smell exhaust fumes (like Tijuana).  And people smoke (a lot more than I’ve… Read more

ipv6… is this thing on?

During the past two Firefox releases (2.0.0.5 and 2.0.0.6) I’ve been running an dual-stake ipv4/ipv6 accessible download server. This box was serving Firefox updates and was part of releases.mozilla.org. I thought I could use traffic numbers to help justify a native ipv6 Internet connection. Here’s what ipv4 traffic looked like during a one week period… Read more

IPSEC VPN between Cisco IOS & Netscreen – solved !

This isn’t necessarily Mozilla related but after spending a month on and off trying to get an IPSEC VPN up between a Cisco IOS router and a Juniper Netscreen SSG5 and finding very little help online, I figured I might as well document it here for others to find (myself, for instance, or, hey Google… Read more

Comcast, Boo!!

I just switched from Vonage to Comcast Digital Voice and noticed the following under Status on digitalvoice.comcast.net portal: Firefox is currently not playing back voice mail messages correctly. Please consider an alternate browser such as Internet Explorer or Safari while we address the issue. Seriously?

Secret ipv6 sites…

If you’re ipv6 enabled, stuff the following into your hosts file and let me know how it goes. 2620:0:330:5::10 www.mozilla.com 2620:0:330:5::11 www.mozilla.org 2620:0:330:5::31 addons.mozilla.org It might even be faster (since you’re probably the only one using those machines)!
