I know Qbasic. I have used Access 2000 and Access 2007, and I currently use Access 2010 to program databases. I've become quite familiar with VBA in the process, and I have used it in several applications utilizing Outlook, Word, and Excel.
I have used VB 6 on a couple of occasions, and I have successfully created a website using VB.NET with an Access 2000 database backend.
I like websites to follow the W3C standards. I am familiar with HTML, CSS, and XHTML. Furthermore, my knowledge of HTML5 is limited.
I have been becoming more familiar with Python and Django and that opened the door for me to learn many more web technologies. For instance, I've learned about the less compiler for CSS, and I just started the tutorial for AngularJS. I understand JSON better, and it's all helped me to improve my understanding of SEO (Search Engine Optimization).
As a system administrator, I've been learning PowerShell, Exchange 2013, and Windows Server 2012. VPN is difficult to figure out, and so is the Cisco ASA firewall appliance.
In short, I know a lot of stuff, but I wouldn't consider myself an expert in much of it. Still, I remember the days of Qbasic, and those were quite fun!
