Agreed, Picard is my app of choice as well! It really could do with a face lift, but it's a powerful tool.

Digital Ocean has a fantastic community base for support on stuff like this, check out this area of their site: https://digitalocean.com/community/

If you're looking for specific help for your paticular setup let us know what you're running on your severs and what stack you've got as well as what exactly you're after more information on (apache for exanple).

If you're just looking to improving your system knowledge, I'd highly recommend getting yourself some system administration books or subscribing to some magazines, there are many out there (magazines probably depending where you live) and lots of valuable free resources online to.

There are lots of different ways to do the same thing most of the time I've found out with this stuff, so it's a case of lots of reading and coming to the best solution, which by the sounds of it you're already doing by using stack overflow and that :-)

I currently use a mix of either hosting on GitHub Pages (which is free and supports Jekyll) or using my own VPS which is hosted at Digital Ocean. I'd highly recommend the VPS route as it opens up a lot of opportunity and is really cheap. Also gets you setting up apache and learning about managing your own webspace. It's a great weekend project and if you don't mind diving into terminal then it's great knowledge to have. In the past, I've used one.com as it's really cheap, but you get what you pay for.
