It feels like we’re starting to pass the peak of the hype cycle of microservices. It’s no longer multiple times a week we now see a blog post of “How I migrated my monolith to 150 services”. Now I often hear a bit more of the counter: “I don’t hate my monolith, I just care that things stay performant”. We’ve actually…
A couple of months ago I did a performance comparison between some of the top free DNS Resolvers available. It was just after Quad9 had…

This website is hosted on a very cheap (£4 a month) VPS. This server has 1 CPU and 2GB of RAM. The slowest part of this website can theoretically handle 4.2 million requests a day. I got these results by benchmarking by websites.
I don’t like to cover “current events” very much, but the American government just revealed a truly bewildering policy effectively banning import of new consumer router models.
