WUG Days 2026 Praha
WUG Days jdou i letos do Prahy. Jedna moje session byla vybrána, takže se společně podíváme na parameterized collections v EF Core.
Automated NTS certificate monitoring
As I’m running my time.cincura.net timeserver I have some monitoring in place. But one thing was missing: checking the certificate for NTS. Although the renewal is semi-automated, having an additional layer of verification provides peace of mind. The challenge is that most monitoring tools do not support NTS, so I decided to create my own tool – which you can now use as well.
CODECON #Žilina
Už za dvacet dní, přesně, se bude konat CODECON #Žilina. Nikdy jsem na této konferenci nebyl, ale Žilina je rozhodně město, které mám rád. A když vidím, na jakých místech se akce koná, nemůžu se dočkat. Moje session je How I put .NET into Firebird database engine. Ano, název je v angličtině (protože jsem hlupák a nedošlo mi, že CfP můžu vyplnit v češtině), ale jinak vám vše samozřejmě řeknu v češtině.

In about two weeks a .NET Developer Conference is going to happen in Köln. I’ll have one session Autoincrement (identity) is not the only option for primary keys.

Application Insights’ sampling ratio affecting other Open Telemetry exports
I have a small .NET application that manages some specific parts of my Software Defined House aka Smart home. Recently, I decided to transition from Application Insights and I found an unexpected behavior when using pure Open Telemetry exporter.
Announcing time.cincura.net – Stratum 1 NTP and NTS time server located in Czech Republic, Europe
Ever since I started building my homelab and started playing with networking I wanted to give something back. Something that’s a valuable service. And although I’m self-hosting a bunch of my websites and providing data from my weather stations publicly, it was not it. Until I stumbled upon timekeeping and time servers.
Techorama (BE) 2025
Next week Techorama in Antwerp is going to happen. And I’m looking forward to all-star sports edition. I was lucky and 2 of my sessions were selected.
Nullable bool and if statement

Testing latency to Azure datacenters around me
Purely out of curiosity I decided to test latencies to a few Azure datacenters around me. Specifically, Germany West Central (Frankfurt), Poland Central (Warsaw) and West Europe (Amsterdam). I wanted to test Azure DC in Austria as well, but it is not yet available.
Techorama (NL) 2024

.NET Developer Days 2024 Berlin
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.

Entity Framework Core 8 provider for Firebird is ready
I’m excited to announce the release of Entity Framework Core 8 provider for Firebird.
Writing “string.IsNullOrEmpty” using pattern matching and comparing the resulting code
I was working on a codebase the other day and it used heavily the pattern matching features of C#. And as I was writing string.IsNullOrEmpty it got me thinking whether I could switch from this very specific method to using (maybe) a more general pattern matching approach. And also, how that compares in performance.

Enumerating over Select’s index
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?

WUG: .NET Conf 2023 – Live Stream
Trhák letošního roku – .NET 8 – 14.11. v premiéře ve Zlíně s celebritami. Řečeno normálně, společné sledování keynote .NET Conf 2023 v rámci WUGu ve Zlíně, následná diskuze s experty a také neformální hospoda. Lepší úterní večer asi těžko vymyslíte (nebo nejste opravdový geek 😄). Tak doufám, že se tam uvidíme.
