Developer Week ’21 7 Jun 2021 1 mins Presentations & Speaking Developer Week ’21 , a new conference for me, is happening from 28 June to 2 July and I’m lucky to be speaking there, although only via the power of the Internet.

Introducing FirebirdMonitorTool – tool for processing Firebird’s trace output 20 May 2021 3 mins .NET, .NET Core, Databases in general, Firebird Last few weeks, on and off, I was reviving, finishing and improving a library, or now a tool if you will, that allows processing of trace output from Firebird. The library started its life probably sometime around 2014, and after a minimal working piece was done, it was briefly, yet successfully, used. Then it was left rusting up until last few weeks. What can it do? Controlling my Sinclair AC using .NET and C# (from Raspberry Pi) 10 May 2021 7 mins Home Automation, IoT As I speculated in my previous post , I eventually decided to try the Wi-Fi option first, because I can try that right here and right now. Gopas TechEd 2021 (online) 7 May 2021 1 mins Presentations & Speaking Už za pár týdnů se bude konat Gopas TechEd , tento rok také online. Já jsem připravil dvě přednášky. Obě plné kódu. I replaced jQuery on this blog with vanilla JavaScript 26 Apr 2021 2 mins Blog, JavaScript, jQuery Over maybe last two years or so, I’ve been reading with interest primarily @alesroubicek’s tweets, where he disregarded (with good arguments) all the all-encompassing JavaScript frameworks and libraries. And then out of nowhere last week, I decided to try to remove jQuery from this blog. Simply to have a personal experience with doing stuff in vanilla JavaScript.

My new AC has built-in Wi-Fi and that brings dilemma into my home automation hacking 5 Apr 2021 3 mins Home Automation, IoT Last week I had AC installed into my house and the unit has Wi-Fi module as a standard option. That brings dilemma to my inner geekiness. As you might expect from me, I want to control the unit remotely my own way. Would the unit have only infrared remote control I would take some ESP8266 board ( Wemos D1 Mini Pro is my favorite) and hack together my own infrared remote with simple API over the Wi-Fi. Because that would be the only way. But now I have two options. Oh my.

Fusing await using and await foreach and await 22 Mar 2021 2 mins C# As I’m thinking about the await using and various usage patterns, my mind sometimes starts to wander into pieces like Task<IAsyncDisposable> , Task<IAsyncEnumerable<T>> and Task<IAsyncEnumerable<IAsyncDisposable>> . And how to wrap that into await using and await foreach making some confusing combinations. This is what I was playing with, don’t expect anything specific. ConfigureAwaitChecker with support for “await using” and “await foreach” 12 Mar 2021 1 mins C#, Roslyn It’s probably bit overdue, but I finally implemented checking for ConfigureAwait(false) in my ConfigureAwaitChecker for await using and await foreach . Why now? I simply (finally) needed it. So, what’s new? Migrated from Disqus to utteranc.es 10 Mar 2021 2 mins Blog In last 24 hours I migrated from Disqus to utteranc.es because I’m done with Disqus. I didn’t mind it initially, but last few years I was more and more unhappy about it. Here’s why and how I migrated. Unexpected finding about “await using var” 8 Mar 2021 2 mins C#, Roslyn I’m now updating my ConfigureAwaitChecker to handle await using and await foreach (release soon, if you’d like to ask) and when trying to handle await using var I was surprised how the compiler interprets that. WUG: (Ne)Známé vlastnosti Azure Storage (online) 19 Feb 2021 1 mins Presentations & Speaking Azure Storage je tak nějak moje oblíbená služba. A za ty roky co existuje jsem nasbíral a taky náhodou objevil hromadu zajimavých vlastností, o kterých možná nevíte nebo nevíte jak je použít. No a tak se na ně podíváme na WUGu 18.3.2021 od 17:00 .

Home automation is heavily stateful and that sucks 11 Jan 2021 3 mins Home Automation, IoT, Z-Wave, Zigbee In programming we like stateless pieces of code, immutable data structures, functional composition, etc. and we value languages, libraries and environments designed with this in mind. Home automation is complete opposite. My new PC (and why I chose the components I chose) 5 Jan 2021 4 mins AMD, ASUS, Hardware, Kingston, Noctua, Nvidia, PC, Samsung, SSD During December I finished building my new PC. My previous PC was not terribly dated or slow (and continues to be used by my wife), but I felt it’s favorable time for update. It’s not balls to wall build, rather something I think is good for my workflow – mostly development and related tasks. I don’t edit movies, stream (or play for that matter) games, etc. I describe each component (in no particular order) and my reasoning why I chose it, your mileage may obviously vary.

Back to C# basics: Difference between "=>" and "{ get; } =" for properties 11 Nov 2020 1 mins .NET I recently realized, the difference between => and { get; } = for properties might not be as known as everybody thinks, based on code I saw multiple times. DevDay 2020: Using Roslyn to improve your codebase 9 Nov 2020 1 mins Presentations & Speaking I have to say, Belgium has a special place in my heart, so when my session for DevDay.be was accepted, I was happy. I would be happier if the conference would be in-person, but 2020 is what it is. Anyway. I’ll be talking about Using Roslyn to improve your codebase . Basically taking advantage of Roslyn’s open design where you can use various pieces of the whole compiler plat...
