One of my favourite conferences – .NET Developer Days – that happens in Warsaw in fall is now having also a Berlin edition. And I’m a big fan of Berliner Fernsehturm.

Enumerating over Select’s index

15 Feb 2024 2 mins .NET, C#

My mind was wandering, as usual when it is not 100% occupied, and I remembered that the Select LINQ function has an overload that gives you the index into the enumeration and it uses an int. So, I thought what’s going to happen if I have longer enumeration and it goes over the range of the int?

Tigo’s support is beyond amazing

19 Feb 2023 2 mins Life, Solar

I recently put Tigo optimizers under remaining solar panels on my roof and also equiped my system with CCA (and TAP). During the whole process I contacted support few times and I was blown away by the quality of it. I don’t think I’ve ever had such an overwhelmingly good experience dealing with support.
