I’ve just written what might be the article for the IT History Journal - about the fastest-spreading virus in history.
Strangely, very few people have ever heard this story.

Time spent on walks, sports, and taking care of your health can now be logged separately in TimeMagic.
I’m honestly horrified at how little time I’ve spent on this over the past month 🥲
Here is the screenshot.
These are only activities; projects can be logged separately in TimeMagic.

Tramway is finally done!
I’ve been building this framework for 8 years, wiped it clean twice, and started over from scratch.
All of that just so Rails applications could have the exact kind of CRUD I WANT to work with.
Over the years, it has been used in around 40 projects.

Almost every developer should have
1. Pet Projects
2. Own libraries
3. Contributions to small projects
4. Contributions to big projects

Updates on my application TimeMagic time.purple-magic.com
Added a new project type, “Tech Startup”
It comes with a set of default activities that are typical for any startup but startup developers - especially solo developers - often forget to track time for, even though they absolutely should.

Most modern website social images are 16:9, and without a description, they look pretty sad in the LinkedIn feed.

I played every mainline entry, and I'm confident that I play four of them at an excellent level. That is thousands of hours invested over two decades.
