And kudos to you for following up with your own exploration. It's so often the case that the most interesting stuff is hidden in what other people are wrong about.

Not as much fun that way.

A valid point! Clearly the correct solution would be for the kernel module to check if the filename contains the substring "32", and if so it should load it as a 32-bit binary.

So I read the other article, and I saw that bit that disagreed with my essay. My first thought was, "Oh, of course that's how it works. How did I get that so wrong?" My only excuse was that this essay was originally a tech ta

I couldn't help myself. Despite my better judgement, I wrote an extension to my original essay specifically dissecting this response. (It's now linked at the bottom of the original page.) Thanks for sharing this transcript with me

If I complain about an answer given to me by one librarian, I'm complaining about that answer and that librarian. If you can find a more knowledgeable librarian somewhere else, that doesn't affect my complaint. But to be clear, th

Look, I understand your point. I really do. But I feel that (perhaps due to one or more of your acknowledged biases) you're applying the wrong context to the situation at hand. Namely: this is INTERCAL. There is no freaking standard. T

Unless `write()` returns an error, in which case rax will contain a negative value. I've had to ditch that shortcut many times because of this.

Nice to see another approach to this subject! Kudos to the author. I have a couple of responses to specific points brought up in the article. The author suggests that the original 45-byte executable no longer works on modern systems. If so,

I find I need to quote myself from 2013, as I can't really add anything further to it: > Wow. I honestly wasn't expecting to ever see this on the front page of HN again, given the current ubiquity of 64-bit Linux. (And yes, bef

I'm afraid that's something I don't have any experience with. However, another commenter mentioned a cool video he did on just this subject, at https://news.ycombinator.com/item?id=21728298 -- so maybe check
