MOOCs (Massive Open Online Courses)

Didn't know these were a thing.

   Robert Zemsky (2014) argues that they have passed their peak: "They 
   came; they conquered very little; and now they face substantially 
   diminished prospects."

Weeks 3-6

From: andrew cooke <andrew@...>

Date: Sat, 25 Jul 2015 11:54:11 -0300

Week 3 jun 08-12 - half week before travelling to japan + japan
Week 4 jun 22-26 - in japan
Week 5 jul 06-10 - installed new OS on desktop; GML parser
Week 6 jul 20-24 - improvements to GML parser; AutoTypeParameters

This is a bit frustrating.  My free time seems to be whizzing past and I
haven't kept records to see what I am doing.

As in the summary above, about half of the issue is that we went to Japan.

Otherwise, I feel I have been putting a lot of time into proggramming Julia,
and not enough on new ideas.  I have a pile of books in the post, butntohing
has arrived.

Also, various health worries.  First vision.  Now something weird in my right
hand / arm (twitching at night).  Unclear if it's the "normal" noise, or
another outbreak.  Don't have enough "hard evidence" of an outbreak and need
to see doctor in 2 weeks anyway, so probably waiting til then (context: every
time I have gone, worried, we have found nothing).

Japanese Graphic Design

Seeing the Tokyo Olympics logo reminded me of one the best exhibition we saw
in Japan recently.  It was a retrospective on the work of Ikko Tanaka.

We tried to find a poster, but failed.  Perhaps one day when I visit Moma they
may have something.

Useful Julia Backtraces from Tasks

From: andrew cooke <andrew@...>

Date: Wed, 15 Jul 2015 20:07:19 -0300

Julia's famously shitty backtraces have improved recently.  However,
exceptions thrown from tasks still lose any information from inside the task.

One simple, but ugly solution is to catch the exception inside the task and
print the backtrace there.  To do that you need this code:

    try
      ...
    catch x
      Base.show_backtrace(STDOUT, catch_backtrace())
      throw(x)
    end
