Multi-line f-strings in #python always struck me as nice-to-have syntactic sugar, but I'm automating an ETL workflow and find they're a great code readability tool - multiple flavours of SQL row terminators, field separators etc handled without a mess of if/else spaghetti. Nice.

If you're working with spot-price-discounted VMs in Azure, don't forget to check all your machines are actually running before spending hours debugging odd error conditions in your code. Imagine how embarrassed you'd be if you forgot to do that *ahem*

TIL that BULK INSERT from a UNC share on SQL Server requires read/write access to the CSV file being inserted. My intuitions around how file permissions work on Windows always seem slightly out of sync with how it actually works...

Hey @eoins and @loige this article on the work you are doing with RenaissanceRe is brilliant - it's great to see your discoveries about Fargate scaling and S3 partitioning out in the wild. Nice work! aws.amazon.com/blogs/hpc/a-se…

I appear to have set up a kubernetes cluster by accident. I may live to regret it.

I learned to program in long Irish winters. Now that we have climate changed ourselves into 28-degree weather in August and I don't know if my internal logic unit operates in these conditions.

Useful instructions for include Google Maps into a React Native app here: medium.com/@kinley.tsheri… When pasting #include <GoogleMaps/GoogleMaps.h> into your AppDelegate.mm, watch out for conditional compiler pragmas so the include gets picked up by XCode!

I made a little finger drawing in sketchbook on my phone and saved it to the desktop of my computer via iCloud. It appeared immediately. An "any sufficiently advanced technology is indistinguishable from magic" moment. Wow.

I messed up my blog with a badly configured Content-Security-Policy header, so I wrote a post about it. karlstanley.com/posts/content-… I will get to the good stuff eventually I promise!

Agile ways of working are about _reducing_ risk. If fear drives you back towards more control and less agility, you'll also be increasing risk, the very thing you're trying to avoid. Real vs. Faux safety 👇
