Sample text

At best, the questioner will be ignored. At worst, some experienced OpenBSD person who wrote all this documentation will take offense at his hard work being so thoroughly discounted and flame the questioner badly enough that his monitor will need three months in the Mayo Clinic burn unit. Keep this in mind before you send an email. Have you really checked everywhere for an answer? Are there any other search terms you haven’t tried? Performing a few extra searches with different keywords is much faster than composing a useful email, and there’s an excellent chance you’ll find the answer to your question.

Everyone got something out of the deal. The best-known software distributed under this plan was UNIX. Compared with modern operating systems, the original UNIX had a lot of problems. Thousands of students had access to its source code, however, and hundreds of teachers needed interesting projects for their students. If a program behaved oddly, or the operating system itself had a problem, the people who lived with the system had the tools and the motivation to fix it. Their efforts quickly improved UNIX and created many features we now take for granted.

OpenBSD specifically and deliberately does not. The OpenBSD community is not trying to be the most popular operating system—just the best at it what it does. The developers know exactly who their target market is: themselves. If you can use their work, that’s great. If not, go away until you can. The OpenBSD community generally expects newcomers to be advanced computer users. The members have written extensive OpenBSD documentation, and expect newcomers to be willing to read it. They’re not interested in coddling new Unix users and, if pressed, will say so—often bluntly and forcefully.
