Welcome to m.ac. These terms are short, because the deal is simple: this is one person's blog, everything on it is free, and what you do with it is up to you.
#The short version
Everything on this site is provided as-is, with no warranty of any kind, express, implied, or wishful. If you keep reading, you're agreeing that whatever you do with this information is on you.
#Tutorials and commands
I write about things I actually run, and I test commands before publishing them. But I test them on my machines, with my configs, on whatever versions were current that week. Your setup will differ in some way neither of us can predict, and the ecosystem moves faster than any blog post.
So:
- Read a command before you run it, especially anything involving
sudo,rm, or piping the internet into a shell. - Back up before you upgrade, migrate, or "just quickly try" anything from Section 4 of any tutorial ever written.
- Test on something disposable first. Production is not a test environment, no matter how confident you feel today.
If a tutorial from this site takes down your server anyway, you have my genuine sympathy, and that is the full extent of what you have. I am not liable for any damage or loss that follows from anything you read here, including the part where it happens at 3 AM.
#Not professional advice
Nothing here is professional advice. I am not your lawyer, your accountant, or your security consultant. These are personal notes from someone who runs his own servers and occasionally learns things the hard way so you don't have to. Sometimes you will anyway.
#Mistakes
There will be mistakes. I fix them when I find them or when readers point them out, but I can't promise any page is still accurate by the time you read it (some of these tutorials will outlive the software versions they were written for). If you spot an error, please tell me and I'll fix it. That, by the way, is the entire support contract.
#External links
Posts link to other sites. I don't control what's on them or what they do with your visit. Once you click through, you're under their roof and their rules.
#License
Written content on this site is released under the WTFPL, which grants you exactly the freedom its name suggests. Attribution is appreciated but not required. The disclaimer above travels with the content, though: whatever you build from it is still yours to answer for.
#Changes
I may update these terms now and then; the date at the top tells you when. Every version will say the same thing in slightly different words: everything here is free, and none of it comes with a warranty.
#Contact
Questions about these terms go to the contact page. Complaints about a broken server go to your backups.
