The slide says something like "run the command `seq 2 10000000 | less` and check `ps`, notice that `seq` isn't running". But that isn't how the processes will behave, `seq` will continue running (albeit blocked) until `less` is dead or closes the pipe.

This explanation isn't correct, since a running `less` would not close the pipe and is still a reader. Writes to the pipe would block until `less` fully consumed it, or until `less` was quit such as with the `q` command.

The text _is_ correct if you add a missing step to `q`uit out of the `less` program. I think this step must have been dropped along the way. Unfortunately the screen capture doesn't show this step either.

The author is on holiday (and enjoying their birthday!) and will get to it when they're back home.

This'll all wait for later, hope you're enjoying a nice mai tai on your holiday.

Before that I hadn't even considered how necessary a product manager or project manager were in software development.

But it was the "No Silver Bullet" essay added as a bonus in my copy that I think about the most. "Never again will we see a 10x productivity increase in a decade", this is self-evident now but must have been crushing to people who had experienced the first compilers, the first high-level languages, the first interactive terminals, and waited for the next incredible leap.

I'm not familiar with the instruction sets of the 6809 but I could also see more compact opcodes, e.g. a JMP with a relative offset can be encoded smaller than JMP with an absolute address.

In modern terms PIC is used for ASLR and is therefore a security requirement. Some arches (I'm most familiar with arm64) are entirely designed around PIC and you need extra hoops to do anything in absolute terms.

We're talking about IP68, where you can take a new phone with you on a long swim.

I wrote a Rabin—Karp implementation in ~2006 as part of the spam and threat scanning stack for the MX Logic mail service. It was incredibly performant, letting us test {n} bytes against an essentially unlimited number of string signatures in O(n) time.

Your illustration is about right, but the angle they're catching now is even a bit further than you've shown.
