The title of this should be:

Links for SW developers to look things up if needed

The claim that SW developers should know all of these things is plain ridiculous. I'd consider myself a fairly successful hacker (sold my small startup to BigTecCo and worked there for a while, licensed them some other code, now working on my own startup again). And I'd say I know perhaps 10% of what's on this list and I have a basic (not very detailed) understanding of maybe 40% more. The other 50% I have no idea about.

However I do know a fair amount of stuff (in detail!) related to my field that's NOT on this list and that's what sets me apart.

So bottom line: Use these lists to look things up. Specialize in what you like until you're really good at it. Be open to learn new things. But don't let anyone tell you that you do need to know all this stuff before you're a "real software engineer".
