Where did Microservices go
JS for ZenStack(Prisma Catalyst For Full-stack Development):
“When I transitioned from the backend development world to the full-stack world in 2021, I found that all the buzz from the popular stack like Next.js, Prisma, and tRPC seems to be around monolithic, people were no longer talking about the microservices.”

Using async keyword in windows runtime components
Creating a background task for a UWP app requires a Windows Runtime Component as host
(for out-of-process background tasks). Among the limitations for creating Windows Runtime Components is the inability to expose Task and Task<TResult> as part of the signature of a public method.

Emailing documents in Office 2016 using VBA
Historically the default ‘Email’ button in Word/Excel had some limitations that made it mostly unusable. It’s tendency not to save messages to ‘Sent Items’ being it’s worst fault, but also the default Subject and Body content weren’t great. To get around these limitations I’d been using a custom ‘Email Document’ button attached to an ‘EmailDocument’ macro. After upgrading to Office 2016 this stopped working.

Using Tags In A Jekyll Blog On Github Pages
Revisited creating a tags page for this blog. Pretty straightforward apart from having to correct all of the post tag formats.
Code by Charles Petzold is an excellent read, “a unique exploration into bits, bytes, and the inner workings of computers”. I thought it would be interesting to write an application to generate the combination of Braille, Morse and Binary found on the cover for any text input. I assumed someone would have done this already as the book is now a good 15 years old. If they have I couldn’t find it.
