Culturally Liberal and Nothing More

From: andrew cooke <andrew@...>

  Nativist demagoguery, in turn, will simply deepen the liberal
  elite's distaste for talking about economic issues as such. After
  all, it will be crypto-racists talking about economic populism the
  most. With politics devolving further and further into pure
  tribalism, this type of guilt by association becomes preeminent. The
  basic political argument, in such a landscape, amounts to "you sound
  like the bad guys."

  ...

  "Our political future: a snakepit of insane fascists on one side, &
  on the other, a Wall Street party that's culturally liberal &
  nothing more." Whenever I talk about this, I get people saying 'lol
  that's already here!' But their cynicism reveals a deeper
  naivete. First, they overestimate how much work has actually been
  done to diversify the elite, which remains stubbornly male and
  white. Second, they don't recognize how much worse this can all
  get. It can always, always get worse. Today, there is a least an
  ostensible connection between the liberalism of diversity and the
  leftism of equality. Tomorrow, even that thin thread might be cut
  forever, and so much the worse for us.

Have to add...

...that there's a worry here.  It's tempting to say that the current
idenitity-based politics doesn't address povery.  But afaik it
actually does, to a large extent, because that is strongly correlated
with race.  To the point where you can argue, iiuc, that the "poor
American whites" are upset largely because they're heading towards the
quality of life that blacks already experience.  Hence the accusation
that it's only news when it happens to whites.

Now, the article doesn't really make that argument explicitly.  It's
talking about a future where indentity politics results only in token
support at the elite level, with little change elsewhere.

Turns out that you can use constructivist maths to prove a theorem
about infinte sets:

Good Bike Route from Providencia / Las Condes to Panul\

From: andrew cooke <andrew@...>

Date: Sun, 15 May 2016 18:39:27 -0400

Panul Parque Publico is one of the few places that I know of that has
legal off-road bike trails.  But getting there from Providencia used
to be a drag - Tobalaba bike path disappears and then there's a steep,
long climb.

However, now that the Las Perdices bike path is working, there's a
much better route.  Simply head South on Las Perdices until you get to
the corner with Departamental (where the path ends).  Cross the river
(continuing South) and then take an immediate right on Ola Salas.
Follow Olga Salas round to the South and continue until it becomes a
dirt road.  After one block on the dirt road, you need to make a U to
the West: turn right on San Joaquin, descend one block and then left
(South again) on Las Perdices, then left onto Lo Canas and right onto
Las Chilcas Norte.

Follow Las Chilcas Norte past the antennae (still heading South) until
Central, where you climb left for a few metres before continuing on
Las Chilcas Sur.  That will get you to Rokas Magellanes (dual lane),
which is where you turn left to start the climb to the park - a
significantly shorter climb than most people face (so you can whizz
past them, yay).

Plum Jam

From: andrew cooke <andrew@...>

Date: Sat, 14 May 2016 19:40:48 -0300

Had enough empty jars to make some more jam, and was thinking I'd have
to experiment with kiwi, pear and apple through winter.  But when I
got to the market there were some late plums available.  Since I
didn't make any plum jam in the summer, and it's a flavour I remember
from home, I decided to change plans.

I bought 3.5 kg of plums and somehow, after removing the stones, still
had 3.5 kg to add to the pan.  To that I added 2 kg of sugar (mixed
white and brown) and the juice of two (rather small and dry) lemons.

I only quartered (or halved, for small fruit) the plums, and so was a
littl concerned about the initial heating and added a little (less
than 100 ml) of water.  It took an hour of gentle heating to bring to
the boil and then maybe a couple more of rolling boil - I had to
reduce things quite a bit.  At one point i squashed a few fruit pieces
with the spoon, but I suspect they would have fallen apart anyway.

These days I tend to cook jam, stirring every 10-15 min, until it
starts to bubble "thicker" ("gloopier") and "catch" on the bottom of
the pan.  Usually I can scrape the pan bottom clean and keep cooking
and stirring for another 15-30 min.  But this time it seemed to burn
faster.  I couldn't remove the burnt roughness from the pan bottom
while stirring so decided to stop heating.  The consistency on a spoon
was only so-so, but I didn't want to mess up the pan or get a burnt
flavour in the jam.

Total output was 3.5 kg (1 litre jar and 5 x 0.5 litres, all full).
Since the jars are full, I'll save them all and taste (apart from pan
scrapings, which seemed fine) later.

For a moment I forgot StackOverflow sucked

From: andrew cooke <andrew@...>

Date: Mon, 9 May 2016 16:49:15 -0300

http://stackoverflow.com/questions/37123682/c-mapping-unsigned-integer-ranges-to-signed

There was a time when that question would have received great answers.
When people like me would have loved to work out how to do it right.
Now it's some kind of glorified homework service.

And look at the poor quality of the comments.  People that don't
understand why the question is hard.  People making irrelevant
recommendations.

Anyway, solution at
