add a pretty page with an overview of topics/sessions.
give the individual sections a bit more space.
move pixl after the time machine session.

it kind of works both ways, but pixl already uses concepts from the time
machine session, such as function calls and objects. some parts of pixl
could be used earlier, though.
move to non-timestamped tutorials.
add gemfile to make installing jekyll easier.
add a layout for the individual sections.
s/portfolio/overview/

somehow i always write portfoli*a*. anyway, portfolia (again) isn't
quite the right name, but as we all know, naming is hard.
adjust headings to match up with the html titles.
split time machine section into two parts.

the first one serves as an introduction to javascript, but needs better
examples and the second part is the existing time machine part, but
split to emphasize that understanding variables and simple functions is
necessary/very beneficial to do that section.
ignore logfile generated by jekyll.

kind of, generated by the background job running jekyll whose output i
have redirected to that file.
link to the overview page.
use the base style for the overview as well.
put sections in a subdirectory of their own.
fix front-matter for 'coding adventures'.
move example code to a subdirectory.
add musical adventures section.

very rough, but marked as unfinished and potentially of interest.
add a stub feedback page.
add a footer to all non-example pages.
highlight questions a bit better.
highlight code a bit better.
