John Adams’ views on emerging technologies, software engineering, and various hacks
I made it to Velocity around lunch as I was dealing with work business, but so far it’s been pretty decent. Thanks to Jesse Robbins for the invite to speak this evening at Ignite, and for access to the conference. The day opened (for me, at least) with the Measuring Performance presentation. The general takeaway [...]
I am speaking at Ignite Velocity (which is part of the O’Rellly velocity conference). I’ll be giving a short presentation on Scaling sites for adult hosting, which will cover technical and operations aspects of building sites to scale for video. I’ll post up slides shortly.
I’ve been using the Unix find command for as long as I can remember, and today I found an interesting inconsistency in the way that the implementation of mtime/atime/ctime searches: Here’s a few examples of how this works: find . -mtime 0 # find files modified within the past 24 hours find . -mtime -1 # find [...]
I’d like to share with you some takeaways from the Web 2.0 conference, mainly in the realm of scaling and web development. John Allspaw’s Capacity Planning for Web Operations: http://www.slideshare.net/jallspaw/capacity-planning-for-web-operations-web20-expo-2008 Why startups need automated infrastructures This talk was pretty awseome. It dealt with automating operations work. http://www.slideshare.net/adamhjk/why-startups-need-automated-infrastructures Scalable Web Architectures: Common Patterns and Approaches (2007) [...]
This article at Slashdot is something the Linux community (and I) have asked for for ages. An embedded version of linux capable of running on the network switch itself, delivering content to users directly at the network layer. I’d always wondered why Cisco hadn’t teamed with Sun during Web 1.0 to put versions of the [...]

This evening at the second Google Campfire, they released their Amazon EC2/S3 killer, Google AppEngine. Based in Python (2.5.2 required), It’s a developer tool that gives access to Google’s computing infrastructure and BigTable, the distributed database that Google runs on. From their blog, it features: Dynamic webserving, with full support of common web technologies Persistent [...]
WordPress, the blog software that this blog runs on has finally released version 2.5 after six months of code revisions and updates. I’ve upgraded the blog and everything worked except for one major issue – I could no longer approve or view comments in the admin interface. If you’re having this issue with WP2.5, the [...]
You be the judge. Aside from the extra memory, the CPU performace is nearly 200% better. 10.5.2 destroys 10.4.8. There is some minor lossage in disk performance because I’m using the onboard AHCI ports instead of JMicron ports, but wow… Leopard is on the left, 10.48 AHCI is on the right. Leopard reports this machine [...]
Last week’s fun was getting Leopard to run correctly on retina, which is a Mac Mini, running 10.5.2. After spending many days patching Directory Services and Postfix issues, it was time to break another machine.I headed into the studio where I’ve got a dual-monitor OSX86 machine running JaS 10.4.8. This is commodity PC hardware, running [...]
