Eloquent Javascript ch.5 – Flattening

In which we are back in the saddle and have a success. After a “wait and reapply later” answer from Hack Reactor, I was discouraged and focused solely on a job hunt for three weeks. That effort continues, but I’m also coding again in preparation to reapply this summer. It feels good. At first I […]


Eloquent Javascript ch. 5 – Mother-child Age Difference

In which I defeat a source of irritation. I’ve sat down to defeat this problem on at least 5 different occasions–maybe 10. Each time I was about halfway into it and got interrupted. I restarted each time, partly because I wasn’t sure of the validity of my earlier approach. Combine that with the fact that […]

Eloquent Javascript ch.6 – Another Cell

The example problem in ch. 5 is so hard and described so minimally (eloquently, in the author’s mind, I’m sure) that I sought out commentary on the book. I hoped some blogger had described the components of the chapter with more detail than our friend Marvin Haverbeke. Forunately I found Gordon Zhu, over at WatchAndCode.com, […]
