We’ve all experienced the performance implications of saving files. We use buffers, and we use them asynchronously. Azure storage has Blobs. They look like files, and they fail like files if you write a line at a time rather than buffering. But they’re not files, they’re data structures, and you need to understand them as … More Cloud thinking : storage as data structures
The Cloud is just someone else’s servers, or a portion thereof. Use the cloud because you want to scale quickly, only pay for what you use, and put someone else, with a global team, on the hook for recovering from outages. You’d also like a safety net, somewhere out there with the data you cannot … More Cloud is ephemeral
In the old world, you bought as big a machine as you could afford, and threw some code at it. If it could fit in memory and the disk I/O wasn’t a bottleneck, everything was golden. In the cloud, however, CPU cycles and disk storage cost real money. Optimisation is key, so long as it’s … More Cloud thinking : efficiency as a requirement
If you’re not paying, you’re the product. But you’re not. In security, we talk about 2-factor authentication, where 2 factor is 2 out of 3 : who you are, what do you know, and what do you have. Who you are is the product, a subset of a target market for advertising, or a data … More Privacy is not your only currency

Smart watches. Smart fridges. Smart cars. Smart cities. Part of my is excited, there’s a lot of possibilities, especially once you … More Botnet of things
In my post about developing in the cloud, I started promising a few nuggets about the project I was working on, and following my diversion onto talks and security, I’m ready to start discussing it again. The project itself is fairly straightforward. It was an excuse for me to try a realistic project in Node.js … More Thoughts on Node.js
After my Post PC post, and with an interest in node.js I decided to see if it was now possible to develop a reasonably complex bit of software, with structure and tests, having nothing more than a Web browser installed. I looked at a few options but decided on cloud9 http://c9.io because it has a … More Post PC? Developing in the cloud.
Having submitted a talk on html5, and calling it “The Language of Cloud Computing” (please vote for it if you are interested), I thought I should take this opportunity to discuss how I see the possibilities of the cloud. I do web development in my day job and we use some of the technology that … More The Cloud Promise
