I showed my wife the first RayLib challenge, and the first words out of her mouth were, “can he jump?” Uh, no. Scarfy can’t jump. So, today I’m going to give scarfy the ability to jump, and add some sound effects for added realism. Watch the video above to see how it was done.Click this […]
I’ve heard great things about RayLib. It is, I’ve been told, so easy to use that all you really need is the cheat-sheet, and maybe a quick look at the examples. To date, I never got beyond compiling and running a few examples. So, it’s time for a challenge…Click here to watch the video on […]
Microsoft SmartScreen is a pain in the butt for developers. It pops up scary warnings for files that it doesn’t recognize, telling the user that they’re potentially harmful. That’s why I got an Extended Validation (EV) code signing key, to sign my releases so that SmartScreen won’t show scary warnings, and won’t scare away potential […]

If you’re writing a network server like I am with ZitaFTP, then you may be tempted to create a custom encryption algorithm to store some data. Your reasoning would be: it’ll be secure because I’m the only person who knows the algorithm. Good old “security through obscurity.”Click here to watch the video on Odysee.I’m here […]
There’s no ZitaFTP Server release this week, because last week I was busy paying down some technical debt instead of making progress. Click here to watch the video on Odysee. What is Technical Debt? It’s a business/entrepreneur term for what builds up when you prioritize speed over good design and engineering. For example, you cut […]
A few months ago I started having trouble where ZitaFTP Server sometimes wouldn’t be able to bind to its data ports. The error was confusing: “permission denied.”Click here to watch the video on Odysee.Permission denied? What? The error would be “port in use” if another program was using it. What’s going on?The Problem: Hyper-VThe problem […]
At least two people felt the need to explain the difference between FTPS & SFTP to me in detail after I released ZitaFTP Server. It’s a testament to how confusing all these acronyms can be. So, what are FTP, FTPS, SFTP, & TFTP? What’s the difference? Are they related? Let’s find out…Click here to watch […]
Kea Sigma Delta had its 10th birthday just over a week ago (14 November). I wish I could say that it’s been a resounding success, but business and entrepreneurship aren’t like that. Most companies don’t even reach this milestone; they fail earlier. So, still being here is a success in itself.Click here to watch the […]
