..no output. It's the exact same URL byte for byte.
Maybe 14 hours is enough that HN allows to post it again. Some score threshold could be involved to allow reposting after certain amount of time as well, to allow something more attention if it didn't get enough attention initially?
I admire anyone who has created a BBS, but I don't understand this. Is it to better learn how to code in C? It is nostalgia? It looks like he spent part of a year on nostalgia. PS: https://amendhub.com/jcs
It predates my lifetime but it’s been really fun to learn about how stuff used to work. (Which I guess is some form of nostalgia)
There’s a bit of a boom in retro computing in general right now. Many independent makers doing hardware and software with cool blogs or YouTube channels.
The funny thing with all of this interest in the computets of my childhood, I have grown more interested in the computers that came before my lifetime.
Not only is it great to see the old spirit of tinkering be revived, but there are important lessons about the nature of innovation from the industry's past.
It refers to a technique also known as "port knocking" which consists of leaving a port closed by default and opening it upon receiving a message by another channel (in this case, a UDP packet).
It was mostly in use when TLS hadn't made it's way into most common protocols
No, that’s not what this is referring to, since that doesn’t involve blocking IPs. This page[1] provides some detail:
> A recent change goes a step further and sends a UDP packet to my OpenBSD firewall containing the IP to be banned, and a small Ruby server running there adds the IP to a pf table, immediately blocking all further IP access from the bot.

The website is made to look like classic Mac OS. And instead of commit hash in the summary of the most recent commit on the top of the page, it says:
Which is also fun :)I like the idea of a code repository as being an ideally complete initial version followed by a number of "amendments".
It seems that amendhub is in fact not hosting git repositories.
It seems that "Amend" is a revision control system distinct from git.

And that amendhub hosts Amend repositories.

Telnet brute-force IP banning by sending UDP packets to a firewall host
