I suppose since flooring and parquet files are built out of blocks, there is some sort of joke here. Not sure what it is though… I was looking at my previous post on Athena, and wondering about how the cost of doing such analytics is driven very much by the
I’ve been loooking at mini PC’s. At home, I have a large, and quite power hungry server that I use for running all my virtual machines. Whilst useful – it does take a considerable amount of power – about 250W all the time. With the cost of electricity these days
I have a data processing problem – I have too much of it. Far far too much… This is a post about exploring data, and how to process a lot of it, using Athena Notebooks which was a fun delve into a world I’d never really tried that much before.
People ask me how to start off in IT as a devops engineer. If you’ve asked me and been referred here – congrats. You are one of the people that made me sit down and actually write out the reasons why, rather than just mumble some half thought out response.Before

I was faced with an interesting one a couple of days back that needed a little time to find a solution. We’ve all probably been there, developers leaving cruft behind, hopefully in QA that is no longer needed. We’d had a check show up some security groups that were basically
In the last article we looked at how EC2 and SSH access worked. Whilst SSH keys offers greatly improved security over passwords and usernames, there are a few issues with it. TOFU, is the first one, and I’m not talking about the slightly odd thing made from soyabeans. Trust on
