As a young programmer this article makes me angry. Sure maybe a lot of us young guys build stuff by using components/libraries/frameworks, heck I don't want to write my own nginx module when one already exists that works well. But saying we as a group don't understand the internals of what we use based off the OP's "asking one collegue" is a bunch of bull. I've read the HTTP Spec, in my free time I read the source and run debuggers on the libraries I use and I think regardless of age almost all programmers do the same. Why? Because we like knowing how things work, we like building things, that's why we're developers. The only difference is that today there's a lot more you can/need to know as opposed to 30 yrs ago where everything was low level and HTTP didn't even exist.
nope, think it probably has something to do with a data register, loading maybe? If not then no idea, I don't go that low-level, c and some x86 is a low level as I care to get.
