Few of my current favorites are Android, Xamarin and Python, though I also like traditional and evergreen languages like PHP, C#, Visual Basic and Java.

Apart from computers, my favorite pastime is bicycling.

Code Fan

Software Developer

Canada

Montreal is the second largest French city in the world, next to Paris. I like the fact that real estate is dirt cheap here, so cheap that software development alone enables a financial capacity to afford a nearly 2,000-square-foot luxurious condo right in the middle of Downtown Montreal, a 5-minute walk from my office, beside the largest and oldest art museum in Canada with visitors and tourists from all over the planet, including Hollywood stars. I've chosen C# as my first language at Code Project, because it is the only garbage-collected language and platform meeting the performance requirements for real-time game programming, proven by Unity. Code must be perfect, providing safety, security, performance, scalability, availability, reliability, maintainability, extensibility, portability, compatibility, interoperability, readability, productivity, just to name a few. C# is the only language that comes close, with Rust second to it. That being said, even C# is far from being perfect. I dream my own programming language, while on my journey to it. We will see how it goes!

A few years back I passed my 50th anniversary of programming. I believe that means it's officially more than a hobby or pastime. In fact, it may qualify as an addiction Smile | :)

.

I mostly work in C# and Windows. But I also play around with Linux (mostly Debian on Raspberry Pis) and Python.

Michael Sydney Balloni

Software Developer

United States

Michael Balloni is a manager of software development at a cybersecurity software and services provider.

Check out https://www.michaelballoni.com for all the programming fun he's done over the years.

He has been developing software since 1994, back when Mosaic was the web browser of choice. IE 4.0 changed the world, and Michael rode that wave for five years at a .com that was a cloud storage system before the term "cloud" meant anything. He moved on to a medical imaging gig for seven years, working up and down the architecture of a million-lines-code C++ system.

Michael has been at his current cybersecurity gig since then, making his way into management. He still loves to code, so he sneaks in as much as he can at work and at home.

Mircea Neacsu

I am passionate about learning new ways of building software and sharing my knowledge with others.

I worked with many various languages including C#, Java and C++.

I fell in love with WPF (and later Silverlight) at first sight. After Microsoft killed Silverlight, I was distraught until I found Avalonia - a great multiplatform package for building UI on Windows, Linux, Mac as well as within browsers (using WASM) and for mobile platforms.

I have my Ph.D. from RPI.
