sudoedit.com! is an independent publication that tends to focus on advanced Linux tutorials, and other topics of interest in the technology world.
My current costs are fairly minimal around 20 a month between email and AWS expenses. I try to keep my costs low so that I can continue publishing at no cost to my readers.
I find websites with endless ad's to be annoying at best, and cogs in a surveillance machine at worst. I won't be a conduit for personalized ad targeting, but I do need to pay the bills - which currently aren't very high, but every little bit helps.
At the moment I'm just trying to get the site to pay for itself - which would be somewhere around $200 for the year.
