       | This book is being written entirely in Pluto notebooks!

         | I had heard of Pluto notebooks but didn't know that they were
         | truly different. The elevator pitch seems to be
         | 
         | Pluto: Jupyter without hidden state.

         | I can't wait to try it out. I did my thesis work in Julia ~5
         | years ago but abandoned it afterwards precisely because state
         | management was so painful. At that time, Julia took 30 seconds
         | to start (compile the plotting library), so you basically had
         | to use live sessions, and they had all the usual stateful foot-
         | guns, which made for a very painful overall experience.
         | Performance was still pretty rough last time I tried it (build
         | caching on the libraries didn't happen on install and even
         | post-install wasn't Just Working), but Pluto sounds like a
         | strong enough mitigation to be worth a try!

       | been thinking for a while.

       | Off topic, but this is a few spots below "Hacker's Guide to
       | Numerical Analysis" on the front page right now. It makes the
       | naming seem pretty silly.

         | "For hackers" is a trick so you don't discourage people in HN.
         | If you omit "for hackers", they'll say it has too much math and
         | therefore no practical use. These are the same kind of people
         | who think that the reason people use math is so they can feel
         | smart about themselves, because practical people who want to do
         | practical things don't need math - they have computers.

       | There really should be a better way to map values. There are
       | numerous functions in R for this, I believe there should be
       | similar functions in Julia. Is that because Julia have good
       | performance so people tend to write loop to deal with this kind
       | of task? And call this hacking?

       | I tried paste the code but it was hard to read. You can search
