Triggering a PHP script when your Postfix server receives a mail
Today I discovered Triggering a PHP script when your Postfix server receives a mail. Looks interesting. Gonna have a read. It references this Postfix Architecture Overview document that is even more interesting, and which I will read first!
I came across these Programming Quotes over on cat-v.org today. Their Bumper-Sticker Computer Science is also good.
My favourite was “You can’t trust code that you did not totally create yourself.” — Ken Thompson
You can’t tell people anything
Today I enjoyed reading You can’t tell people anything.
The End of OS X
Today I read The End of OS X. I particularly liked the bit about the Unix philosophy:
- Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new “features”.
- Expect the output of every program to become the input to another, as yet unknown, program. Don’t clutter output with extraneous information. Avoid stringently columnar or binary input formats. Don’t insist on interactive input.
- Design and build software, even operating systems, to be tried early, ideally within weeks. Don’t hesitate to throw away the clumsy parts and rebuild them.
- Use tools in preference to unskilled help to lighten a programming task, even if you have to detour to build the tools and expect to throw some of them out after you’ve finished using them.

Scaling to 100k Users
Today on r/programming was an article Scaling to 100k Users which discusses the phases you go through as you grow.
