Fantasic example of code written in a procedural language (C) in an object-oriented way,with clear separation of responsibilities.
The framework that Wietse created to structure Postfix is, from my perspective, a thing of beauty. I don't doubt that this has been done elsewhere, but Postfix is the first real example that I came across of a somewhat-large application structured in a very clean and understandable way.
Well worth spending some time perusing the code.
You can do log shipping with mysql to have multiple sync'd databases - I've set this up in a small environment, and have not tested this feature with a high-capacity database, but the capability *is* there.
Nothing kills progress than having to create documentation that will never be read or updated.
Don't get me wrong - certain types of documentation are important (overall systems design, data models, for example). But unless you're going to continue to use the documentation after the project has been completed, don't bother creating it.
What most people seem to forget is that if you don't plan on maintaining all the documentation you create, you're wasting your time. Once a document is out of date, it no longer serves it's purpose. I'll expand on an adage: Outdated and incorrect documentation is worse than no documentation at all.
I know I'd be completely lost without LaunchBar on OS X:

I initially thought that entering keyboard commands to run a program was completely opposite what a GUI was supposed to offer, but being a command-line driven guy (hey, I'm getting old!), it was amazingly intuitive, not to mention blazingly fast. I rarely use the toolbar to start programs any more, let alone navigate through the Applications folder.
Definitely recommended for all you OS X folks out there.
I've always had issues with comparisons that follow the 'constant == lvalue' format. For whatever reason, it always takes me longer to grok what the comparison means. When I use 'lvalue == constant', it makes much more sense. At least to me.
I'm not sure why you say this has anything to do with 'safety' - can you elaborate? I'm curious.
I will say that I've noticed this coding construct more in code written by developers from Asia and India. Something in the curriculum, perhaps? In my formal education I never saw the 'constant == lvalue' construct, and I went to University in N.A.
The U.K. has the world's largest civilian stockpile of plutonium.
A civilian stockpile? Can someone explain to me how the UK has a civilian stockpile of plutonium?
What, did we go through a time warp? Wasn't there a Moonbase Alpha back in 1999?
And, didn't the moon vacate the premises shortly thereafter?
D'oh! That should have been "now it's accelerating".
(sigh) I don't know why I bother to preview
...but Star Wars will be soon (or is it already?) part of the list of those shows that 'Jumped the Shark'.
With Lucas at the helm, the death spiral has been been underway for a while, and how it's accelerating.
This sounds very much like http://en.wikipedia.org/wiki/Literate_programming/, as introduced by Knuth.
I looked at using Tangle and Weave for C development a long time ago, but found that it was a pretty difficult paradigm to get used to.
FYI, TeX and Metafont were both written using Tangle and Weave. Pretty impressive to read the source code, which had both code and documentation intermixed. It was a novel way (as in innovative, and as in a book
At my company we have a change freeze from mid-December to mid-January to avoid problems such as this. With a large (40B+) company, you need to have a stable environment to perform year-end financial activities, and an outage like this would be completely unacceptable.
While I don't personally use a Blackberry, I would be asking some serious questions about their change policies before I relied too heavily on a BB for business purposes...
I do not think that word means what you think it does.
