speaking to &quot;you&quot; rather than throwing vague shade at the group of all sysadmins is merely direct, not confrontational. it is not an expression of outrage to point out how weirdly passive aggressive the remark was.<p>the sysadmin is a subset of hacker, a culture proud of its  autodidactic tradition. and the spirit of the internet is to share useful information once you&#x27;ve learned it. it is totally appropriate to come to this website and post that you were interested in the subject of security in networked file systems, didn&#x27;t know what the acronyms meant, and here&#x27;s that information if anyone else wanted to know.<p>it is extremely important to learn how to learn. and i am genuinely curious about this apparent expectation that literature in a highly technical field should have a glossary everywhere. would you expect a blog about routers to always explain what TCP&#x2F;IP stands for?
