Well... but you are not considering union fields and flexible arrays!
With flexible arrays, for example, you actually need to know the size of the message.
Under certain conditions this doesn't means a size field: for example you could use the file size to compute the size of the array (obviously, if it's not encrypted somehow).
But over the wire, this is a great way to build very funny parsers. 😉

Actually it's very easy to add pointers. Consider what you can do with function pointers in a struct, for example.
Really? Didn't know it.
(It worth noticing that I actually did something like this, somewhere... and they worked like a charm)

If you were design the worst possible file format, one which maximizes the number of bugs in its parsers, what features would it include?
Let me start:
Length-prefixed everything. Containers (lists, dicts, etc) have a length field in bytes, but all the items inside them also have their own length fields.
Structures' memory dump.

The reason I’m terrified of “Software Eating the World” is because I’ve seen what’s in the software. And who pays for it

@helby I think I still have only HTTP/0.9→HTTP/1.1 for most shit here.
And HTTP/3 + QUIC will not set foot into my computer.

If you're in the EU, then that's very likely illegal. You should officially inform your professors that they're violating the #GDPR by forcing you to transmit your private data (IP number, name, student ID number, school name) for unnecessary reasons outside of the EU:

Your school could have to pay millions of euros in fines.
"But the pupils/their parents already signed a GDPR declaration on paper" does not make the privacy violation legal.
Guys, to #SysAdmin is not for the faint-hearted!

Well well - this looks most sensible: https://fsfe.org/news/2020/news-20200424-01.en.html h/t @alcinnz - now the question is: when will NZ follow suit? Because it's obviously the right thing to do.

With two daughters at school, @alcinnz, you might know how I feel these days.
The worst issue is that many #Italian #teachers have been trained through #GAFAM webinars: people absorb them as #training while it's just #marketing.
Yet there is hope: I'm slowly spreading #Jitsi #selfhosting.

Hello #Fediverse's friends!
I've been so taken between family and work during the Italian lockdown, that I wasn't able to enter much here!
