Languages used for various apps
Are you interested in the architecture of the apps? Did I make a poor choice? Feel free to flame me.
Packet Sender Desktop: C++ using Qt SDK
Packet Sender Mobile: C# using Xamarin SDK
Cryptoknife: C++ using Qt SDK and Crypto++. Web version uses OpenSSL.
Pay Down Calc: HTML5, PHP, MySQL
My blog: PHP, MySQL, Smarty templates
All sites are hosted on Ubuntu Server LTS using LAMP configuration. Every site was custom-built except for these forums, which use Vanilla Forums software. I now consider Smarty templates a poor choice, but I am not bothering to rewrite.
