> pip allows it but it's with a timestamp

A PR to be able to use a relative timestamp in pip was merged just last week

I used to like having a "depend" target to make the dependencies explicit and so minimize build time, although that fiddles with the contents of the Makefile (some discussion at https://wiki.c2.com/?MakeDepend).

The standalone makedepend(1) that does the work is available in package xutils-dev on Ubuntu.

Is it coming? I notice that OpenSSL now has support for raw public keys.

The spec (RFC 7250, "Using Raw Public Keys in Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS)") suggests DANE/DNSSEC as a mechanism to bind identities to public keys (section 6).

https://datatracker.ietf.org/doc/html/rfc7250

Will this really be simpler?

There was a sense of "wasting a port". A modern Linux /etc/services has only 200 or so reserved TCP ports (out of a possible ~50k) so that fear might have been overblown.

I suspect the bureaucratic overhead of needing to go to IANA to reserve a new port might have had a chilling effect. See:

> you are supposed to still continue if you strictly follow the standard

Which standard? RFC 3207 (for STARTTLS over SMTP), 2002, says: "If the client receives the 454 response [TLS not available], the client must decide whether or not to continue the SMTP session".

You still need to pull out the paths?

A sprinkling of grep/perl (awk/sed/ruby/...) is mostly good enough eg:

strace -e trace=%file cat /etc/passwd 2>&1 >/dev/null | grep ^open | grep -Po '(?<=").*(?=")'

You can use "-e trace=open" to trace only open(2) calls

Alternatively "-e trace=%file" to get all file-related system calls (will catch eg failing pre-emptive checks using access(3) -> stat(2)).

> original definition of "hacking" was "hacking code together"

Hmm. Right spirit but not so much "hacking code together" going on at MIT's Tech Model Railroad Club in 1958.

"a project undertaken or a product built not solely to fulfill some constructive goal but with some wild pleasure taken in mere involvement, was called a `hack'".

(Steven Levy, "Hackers").
