A warm, polished notebook for software architecture, learning, travel photos, and wallpapers. https://nullabletype.dev/posts/ I’ve been eyeing up a 3D printer for years, but always found it difficult to justify the cost. Yes, there are cheap-ish models, but they generally come with their own hidden costs, such as time spent fiddling with settings to get good prints. I have plenty of other things to waste my time on already.

One thing that has become apparent, through keeping up with the whirlwind of changes, is that people are still figuring out how to use these tools effectively. It seems like every video I watch, or article I read, people are swearing they’ve found the killer approach.

As far as I could find, NHibernate doesn’t expose any really easy ways to intercept and manually log both the SQL and execution times for each query.

I was only the second C# developer at the company, lacking experience other than dabbling a few times in and out of modules. The other developer was our now Chief Technical Officer. He had single-handedly architected a C# system already in use at universities across the UK. On top of that, he was the sys ops engineer at the time, provisioning and looking after hardware for hosting, amongst other things.

You’re more than that can cover. The person reviewing your CV knows that, but they face a difficult decision on whether to invest the time to get to know you based on this first introduction.
