So I got a #Java Father's Day card from the 18 year old who seemingly survived AP Comp Sci. Plus a cameo from the best cat of all...

With the 20yo back at college to lab-rat for the summer, and the professor spouse in Brasilia for a few days, I cooked up a wicked sous-vide and pan-seared salmon plus apple/spinach/nuts/sweet peppers salad and rice for the college-bound 18yp and myself. Worked out quite well.

The @TheEconomist hires @gelliottmorris and BAM there comes a fancy predictive model of the upcoming mid-term elections.
Nice writeup and charts -- but your explanation of “elastic-net regularisation” describes standard k-fold cross-validation. nitter.vloup.ch/EconomistOnce/st…

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 ...
