Don't use Hadoop when your data isn't that big
"So, how much experience do you have with Big Data and Hadoop?" they asked me. I told them that I use Hadoop all the time, but rarely for jobs larger than a few TB. I'm basically a big data neophite - I know the concepts, I've written code, but never at scale.

Why I left Heroku, and notes on my new AWS setup
On Friday, we migrated Soundslice from Heroku to direct use of Amazon Web Services (AWS) . I'm very, very happy with this change and want to spread the word about how we did it and why you should consider it if you're in a similar position.

GoDaddy, Media Temple, and the Horrible World of Web Hosting
There’s potential for massive profits: most customers of shared hosting and VPSes never come anywhere near their resource allocations so the machines can be extremely oversold, and most dedicated-server customers keep paying the “new” price of the server every month for years after its value has plummeted through the…

Air Gaps
Since I started working with Snowden’s documents, I have been using a number of tools to try to stay secure from the NSA. The advice I shared included using Tor, preferring certain cryptography over others, and using public-domain encryption wherever possible. I also recommended using an air gap, which physically…

Why I Dislike EC2
EC2 is great if you need per-hour billing and instance provisioning. For everyone else, which is most, it's just really expensive and slow hardware.

Apple Developer Center still down
It’s now been almost three full days. I don’t know anything about their infrastructure, but for a web service to be down this long with so little communication, most “maintenance” or migration theories become very unlikely.

Replace Dropbox with BitTorrent Sync and a Raspberry Pi
I like to take long running notes, jotting down an idea here and there when one pops up. I never know which devices I will have with me, so I like to have these notes synced across all of them.

Marelle: logic programming for devops
In the past, walking the uneasy borderline of academia, I used to managed compute servers for my research group. New hardware was a rare godsend, configuring it by hand was natural. At 99designs, I’ve been privy to the opposite approach: machines should be disposable. This requires the entire setup of a new machine to…

Things I set on new servers
There are a number of things you can do to make a server more secure whilst protecting your hosted entities and their users. Here are just three of the many things I do on every new server I commission. I hasten to add that these are not necessarily the most effective or at the top of my list - they are just that: 3…

CDN vs S3
As I said in my last post: S3 is NOT a CDN. It is an amazing Simple Storage Service, not a Simple Delivery Service. Via AWS: Amazon S3 is storage for the Internet. It is designed to make...
