About NP's Tech

Just thought I'd try to populate this sub-forum with a few questions about the technical side of NP.

1. Do you host it yourself, or do you have a web-hosting service you use? If so, what service?
2. If you do host it yourself, what specs are the server?
3. What languages/services do you use for front-end and back-end handling?
4. Did you manage to register your own HTTPS certificate, or did you purchase it from somewhere? If so, where?
5. 57 68 79 20 64 69 64 20 79 6f 75 20 67 6f 20 74 68 72 6f 75 67 68 20 74 68 65 20 70 72 6f 63 65 73 73 20 6f 66 20 74 72 61 6e 73 6c 61 74 69 6e 67 20 74 68 69 73 2c 20 77 68 65 6e 20 79 6f 75 20 70 72 6f 62 61 62 6c 79 20 6b 6e 65 77 20 69 74 20 77 6f 75 6c 64 6e 27 74 20 62 65 20 61 6e 79 74 68 69 6e 67 20 67 6f 6f 64 ?

All of the following answers are probably somewhat disappointing.

Web hosting service. I use NearlyFreeSpeech.net since it's a bare bones low cost service.

N/A

Everything is just written in raw PHP, no framework. This codebase is about 7 years old now.

My host handles this.

Seeing that it was mostly hex numbers in the 60's and 70's, I knew what it was and just googled hex to string converter and clicked on the first result. I removed the spaces by pasting the string in notepad and using replace-all. Entire process took about 15 seconds.
