About jperras

I'm a failed physicist turned software developer. Life is weird like that.

I sometimes say intelligent things on Mastodon: https://hachyderm.io/@malware

I used to be, and sometimes still am, on Twitter: http://twitter.com/jperras

I write about things that interest me at https://nerderati.com

    16 year HN vet here. This place has both changed a _lot_ and also very little, depending on which axis you want to analyze. One thing that has been pretty consistent, however, is t…

    I thought the same, and went from an Apple standard keyboard to a Moonlander. Some time after that I went to a custom 36-key split ergo board. It takes a little time to familiarize…
