Nikon Z 100-400 centre vs Nikon 80-400G & Sigma 150-600 C

This is the second post in a series of evaluations of the Nikkor Z 100-400. Please refer to the first post for details about the test equipment & methodology. In this post, I’m going to compare performance in the image centre between these three telephoto lenses at 400mm: Nikkor Z 100-400 (e.g. from Amazon). AF-S … Read more

Nikon Z 100-400 centre performance

Last week my Nikkor Z 100-400 arrived. I’m in principle upgrading from the AF-S 80-400G, which has been my all-time favourite lens (both sentimentally and in terms of the yielding the greatest proportion of my favourite photos). Of course, it’d be nice to see how those two lenses actually compare – I suppose I could … Read more

Attention trumps experience

It’s always bemused me that I did better in electronic engineering than computer science. I studied them simultaneously, receiving degrees in both after five years (some classes counted towards both, thus why it wasn’t seven or eight years).

This is bafflingly hostile behaviour for what is supposed to be a beta version of the browser that users voluntarily, out of … Read more

The Abstracted Unreliability Anti-pattern

I don’t know if it’s genuinely on the uptick, or just coincidence, or merely runaway pattern recognition on my part, but I keep seeing the same logical fallacy applied over and over again: if I add more layers to a system it will become more reliable. A recent example: this set of services have poor … Read more

People vs Products

I’ve experienced an interesting arc over my twenty or so years (thus far) of software development. I started out as a one-person shop, doing my own things, selling shareware. I had no manager nor technical lead. I had to make all my own decisions, in all aspects, without guidance or assistance. Subsequently, during my four … Read more

Why I wanted to intern at Apple

I just found this while reviewing some very old backups. Like most things of this ancient era, I’d completely forgotten about it, so it’s been fascinating to look back – as if in the 3rd person – at my younger, far away self. I don’t recall why exactly, but evidently I had to write some … Read more
