I'm thinking of this in a "pitfalls of being self-taught" context, but I'm sure there's plenty of other places these moments happen. Feel free to also interpret the title as "How did I not know that?", "How did I miss that?", "Why did no one tell me that?" and the like!

The inspiration for this post is that I am over a year and a half into my Linux journey, which has involved a solid amount of tinkering and eagerly getting familiar with the command line, and I just now realized that you can do man <literally any command> to quickly get to the manual for it. And also that whatis exists. For the last 18+ months, I've been just doing <command> --help or <command> <subcommand> --help and searching the internet to supplement that. I knew that man pages exist, but I guess for some reason it didn't occur to me that there would be a way to access them that easily.

I love learning things on my own and building understanding by doing, just picking a direction and running with it, but... man. I often wonder how many little things that "everyone knows" I've missed through sheer random chance. And then there's things like my man pages revelation that I can't believe I didn't piece together on my own, considering all the other crazy stuff I've figured out. Oh well lol. I suppose it's good when the humbling reminders of my own capacity for ignorance arrive via something low-stakes like this than via something that could wreck my system!

Anyone else have similar stories to share?

Stop me if you've heard this one before:

• You get an idea for something you'd like to learn more about. (Maybe you have a question, maybe you want to explore a new hobby, or maybe you want to make a more informed decision.)
• You type something into a search engine.
• You click a result, only to realize that what you're reading is poorly written. It seems rushed, surface-level, and ill-informed. "This doesn't answer my question at all!" you think to yourself.
• You go back, and try another one, and another one, only to give up and put the idea back in your head.

I don't think these webpages are written to be useful in the first place. They seem to be written to attract attention to the website for other reasons (ad revenue, affiliate links, to draw attention to a product or service). Regardless of why it's happening, though, I want to find a better way to search.

The sort of content I'm looking for is written by someone who really cares about the topic. I want to learn from dorks and nerds and passionate people. Once I stumbled across this blog about extra virgin olive oil. The website isn't pretty, and it goes way more in depth than I'll ever need, but I trust the author, and there are some really interesting nuggets of insight on these pages. (e.g. "Another myth debunked: Heating EVOO makes it ‘toxic’")

Do you have any tips or tricks to more reliably find these sorts of sources (whether online or in-person)?

Hey everyone, I've decided to start studying to get my CCNA. My books are showing up Monday and I'm really excited.

I'm going to shoot for self studying and prep for the testing. I think I can do it as I've always thrived in a more self paced learning environment (I also have no money for the classes).

I'm just wondering if anyone has any tips, supplemental material, etc they could recommend? What was hardest for you and what was easiest? What did you spend too much time studying and what didn't you spend enough time on?
