Very cute, if I understand correctly.  Chinese router modifies JS of incoming
requests to make requests to github.

Dublinesque

I'm reading this book (in Spanish), and it's rather good.  Here is an accurate
review -

Also, a book by the author of the review, that sounds interesting -

Word Lists for Crosswords

From: andrew cooke <andrew@...>

Date: Mon, 16 Mar 2015 20:31:23 -0300

If you use a computer to help with crosswords (I guess this is an admission of
guilt) then you may be frustrated with /usr/share/dict/words.

Happily, it's easy to generate new lists.  Simply download scowl from
http://wordlist.aspell.net/ and generate a couple of lists like this:

  ./mk-list english 50 > words-50
  ./mk-list english 95 > words-95

words-50 is a good starting place; words-95 is for when you get desperate.

3D Printing and Speaker Design

From: andrew cooke <andrew@...>

Date: Wed, 11 Mar 2015 08:05:27 -0300

I was brainstorming what I could do in my spare time if I quite work.  3D
printing seems to be more and more popular, and I've been toying with the idea
of writing GPU code to model air pressure / flow, so why not combine the two?

The idea is to model some complex shape (selected using, say, genetic
algorithms) that gives an optimal response when used as a speaker housing.
The hope is that an arbitrary shape would allow exact tuning to match the
speaker, giving good response in a small package.

3D printing should allow "arbitrary" shapes to be developed.  Size limitations
mean that it would be restricted to smaller speakers for now, but that might
change.

Rowhammer - Hacking Software Via Hardware (DRAM) Bugs

From: andrew cooke <andrew@...>

Date: Mon, 9 Mar 2015 22:02:59 -0300

http://googleprojectzero.blogspot.com/2015/03/exploiting-dram-rowhammer-bug-to-gain.html

You can flip bits (with some hopefully quite low probability) in DRAM by
targetting nearby bits.  And then it's just hard work.
