Read/write/execute file permissions.
Having them set incorrectly can cause problems, such as creating a file as root then leaving you unable to modify it as user, being unable to execute a script because execute is not set, or being unable to use your SSH keyfile because you left the permissions too open.
It’s more actually like “Why is it, when something doesn’t happen, is it always you three”
It’s a disaster out there right now when it comes to decent review sites.
Google is absolutely complicit in this, if not entirely to blame. Their search ranking has over the years pushed to the top all the low effort listicles that are full of sponsored Amazon links and no actual reviews, and a lot of the real reviews have disappeared due to traffic starvation.
And now those top sites are often just AI nonsense that steal content from whatever few other sites actually exist. Nonsense “reviews” just spouting the product specs, from people who have never even put their hands on the product for real.
My personal go to these days (although I wish it wasn’t) is youtube.
There’s still a load of nonsense listicles on youtube, but with a bit of searching you can usually find some actual person who is genuinely knowledgeable about the product category, and has a bunch of different ones actually in their possession for real, that they can compare and give honest opinions on.
