Welcome to Trance Cat

About the admin: Likes to program. Made simple applications in C#, Java, and PHP. Made PCB circuit boards. Likes Gintama.





"Trance Cat" is the name of this website because it was the best name I could come up with which also had an available domain. I don't think I would like to change the name anytime soon, as I've already got some traffic; besides, I'm just fine with "Trance Cat".

My future plans would be to add an English locale to some of my programs. I know I can do that now, but I'm so lazy and I would rather program than translate(make a new locale), but I still plan on doing it eventually as I would like to distribute my programs more widely. Other plans might be to make this site HTTPS but I know that wildcard SSL certificates can be quite expensive, but I am still considering that. I most likely will buy it if HTTP/2 becomes available on this server.

Till then! Trance Cat
