It is also the opposite of what made Open Source / Free Software great :
- cooperation in kind
- the best design winning
- friendly (and mostly cooperative) competition.
These days, it looks more like the "embrace + extend (+ extinguish)" playbook. Which is pretty sad.

Boo-hoo, the list misses @CRANberriesFeed which is the mother of'em all and has been available since July 2007 (!!) via RSS, and for many years via Twitter too.

Easier still if you use the `a` switch for automagic compression extensions:
tar caf "compress any file"
tar xaf "xtracy any file"
tar taf "list any file"
and so on. Works with gz, xz, bz2, ... Try it!
I can't remember where I first saw it, but still useful mnemonic (with an exaggerated eastern European accent):
tar czf: "compress zee file"
tar xzf: "xtract zee file"

Took me three days to notice @CRANberriesFeed was asleep, and nobody else cried foul either. Code is now fixed, and we should get a flood of updates of the next little while.
A safety-valve in the CRANberries code was an old value, and too low for the current size of CRAN. So the script thought something bad happened, and did not update---but it was "just" a more rigorous purge at CRAN.
Service will resume in a moment. Expect a flood ...

It is a really wonderful example, describing over 3 1/2 pages how S3 classes can be lightweight and effective for the right problem size.
The book is from 2000, which is when I bought my copy. I once heard rumours of a 2nd edition but that was years ago, and never happend.
Sometimes the classics, e.g. S Programming by Venables & Ripley, give the best examples. Great practical breakdown of an S3 class without relying on decomposing the `lm` object (and, that's quite a rabbit hole). Thanks @eddelbuettel for the heads up.

R 3.5.0 is out, and Debian packages have been uploaded to "experimental".
We will get a binary transition going for the required package rebuilds.
