Several years ago before the unified AWS CLI was released I wrote about installing the EC2 command line tools. Now it’s time to update that. It goes without saying that over the decade Amazon has been providing cloud services their interfaces and tools have matured greatly (along with their overall offerings). Early on Amazon didn’t […]

Use PowerShell to Save Excel Worksheet as CSV
I’m working on a PowerShell script to launch some virtual servers on VMWare based on input from a CSV file. To create the CSV file I’m using Excel, and I have more than one worksheet in the Excel workbook. Since it’s a bit of a hassle to use Excel’s GUI to save a given worksheet […]
History of Internet Addressing
Volumes have been written about the Internet and its protocols so what I have here is nothing new or ground-breaking. It is, however, a good overview of the history of IP addressing, related Request For Comments (RFC) and other links. I’ve been working with the Internet Protocols for a while, including data center builds, network […]
How Did One Guy Build A World Class Web Infrastructure Serving Over One Billion Calls Per Day?
On Monday, December 15, 2008 I went to work for an online video start-up. On my first day our video players loaded on 384 of our partner’s web pages. As you can see from the first chart that was actually a pretty good day for us (it was actually our biggest day to date) as […]

Crunching Billions of Log Lines With LogParser
Yesterday three different people came to me asking what type and how many browsers are our “users” using to access our content. Since our products load on about 50 – 80 million pages a day we have a pretty good sample size. And a hell of a lot of log files to collect and analyze. […]
Improving Web Services (Part II)
Last year I wrote about how we improved web server performance with some fairly small changes, and about how I keep an eye on these metrics with reports I create analyzing my web server logs with Microsoft’s LogParser. This is a follow-up to those. Recently we did an upgrade to our platform. One of the “improvements” was […]
