I’ve noticed an issue recently after upgrading a few Blazor projects from .NET 5 to .NET 6 where the UI flashes after every call to StateHasChanged. Something like this:
Yeah, that’s not annoying at all. Unfortunately it was happening in quite a few different places and was pretty darn noticeable, so it looked like I was going to have to dive in and figure out what exactly was causing this to go wrong (despite working perfectly in .NET 5)!
Blazorise is an excellent library that I’ve been using a lot lately. While it has great support for declaring custom visual themes, you’ll occasionally run into situations where what you’re trying to do isn’t fully supported.
Take this super contrived example: I want to set the shadow on a div to use the primary colour defined in my theme, but there’s no attribute in Blazorise to do this directly (at time of writing). I could hard-code the colour to the same hex value as what I’ve set in my theme, but not only is this generally bad practice (since it’s easy to update one value and not the other), it locks you into only one colour even though the theme can be modified dynamically during runtime. So how can we access our Blazorise theme values in custom CSS?
I’m sure I’m not the only one that has “temporarily” stored passwords, application keys or other development secrets in appsettings.json simply because it was easier or faster than doing it the right way (although if I am, this first sentence will surely come back to haunt me).
I get it. It happens! This blog post actually comes from my efforts to update a project I’m working on with some friends so that we’ve got a more consistent approach to keeping secrets… secret.
So how are we going to go about this? We’ll be using Secret Manager, a fantastically helpful tool built into the configuration API in ASP.NET Core that will let us keep the secrets out of appsettings while not require a change to how we access the settings in code. Sound good?
EVieBikes recently landed in Guernsey, bringing the first ever dockless shared electric vehicles to the island. I got into contact with Gavin Breeze (founder and CEO of EVie), who kindly agreed to discuss with me where EVie came from, what the service means for the islands and their plans for the future!
Interview conducted on 2021/04/09.
A Brief History of EVie
According to Gavin, EVie bikes were “sort of all [his] fault”. After founding a software as a service (SaaS) payment company called DataCash and selling it to MasterCard, he found himself at a loose end. Deciding that he was “too young to sit around doing nothing” Gavin looked for his next project, which came shortly after hearing Phil Male (Chairman of JT) discuss a number of ideas he had for improving Jersey. Of the ideas put forth, Gavin decided that “as a private individual the only one [he] could have the […] remotest impact on was to try and move the dial towards the islands becoming all-electric islands” (moving away from internal combustion engine vehicles).
I’ve been writing regular expressions (regex) for years and would consider myself pretty good at them by now (I decline to provide references). The problem is that although it’s common to see regex as cryptic and painfully terse (which are not invalid points), they remain one of the best ways to handle complex pattern matching and as such you’ll probably run into them at least a few times in your career.
Even if you really despise writing regular expressions, here are some tips that will help to make that process as painless as possible!

My wife and I finally got a new printer to replace the old one that has pretty much given up the ghost and refuses to print anymore (often considered an important feature for devices like this).
We settled on an Epson ET-2711 in large part because of the ink tank that should (hopefully) do away with the constant stream of expensive cartridges in favour of some cheaper-per-page ink bottles. I was excited to get it out and start setting it up (in part because we’re in another lockdown and what else is there to do right now)!
Imagine my frustration, dear reader, when I found out that the whole wireless setup process for this printer is terrible if you follow the official instructions. I genuinely spent a couple of hours bouncing between the Android app (which gave me a very helpful message telling me “Communication error”, to check the printer is on and not much else), the included software for Windows (which was just as helpful), the printed documentation in the box and the website, all to no avail.
The good news is that I finally figured out how to get it working. The even better news for you at home is that I’ve gone through the process three times so that I could document all of the steps to get this working properly!
I’ve been using KeePass for my password management needs since early 2014, but I recently decided that I wanted to move to something a bit more substantial. KeePass is an excellent (open source!) piece of software, but since it stores passwords in a single database file the only way that I could really sync it between multiple computers and my phone was to store that file… in Dropbox.
Yeah, as you can imagine that’s not a great solution.
Anyway, I wanted to move over to 1Password but when I tried searching for “Migrate KeePass to 1Password” I kept seeing references to 3rd party scripts I’d need to use to convert my exported data (no thanks) or that it would require a bunch of manual data entry. After giving it a go though, I can tell you it was actually ridiculously easy and straightforward and didn’t require any external tools or scripts! As such, I decided to put together this step-by-step tutorial for migrating your data from KeePass to 1Password!
I’ve spent the last couple of evenings trying to get a set of Azure Functions migrated from .NET Core 3.1 to .NET 5 so that I can play around with some of the nice new syntax options, nullable contexts and the like. Since .NET 5 has officially been released, it would be justifiable to believe that it would be well supported across the core Microsoft product catalogue, such as in… say… Azure Functions?
Mark Twain once wrote that “there is no such thing as a new idea” and quite frankly I’m starting to agree with him.
I’ve spent the last month or so actively trying to come up with some ideas for projects/ blog posts to work on that would be interesting and useful. The issue I’ve run into is that almost every time I come up with something, I give it a quick search only to find out that it’s already been done (sometimes many times over). That means another idea goes on the pile to be abandoned since “there’s no point in doing it anymore I guess”.
