Jon Udell Reviews Beautiful Code, Expert Minds

I only dabble in software programming occasionally (usually in Python), but I do pay attention to what programmers are doing because I believe the skill of programming is one of the most important achievements of the 20th and 21st centuries. Without programmers our handsome hardware computers would merely be pieces of furniture.

This item is from Jon Udell's blog and reports on a collection of essays compiled by Greg Wilson and Andy Oram, Beautiful Code: Leading Programmers Explain How They Think: "The idea is to get a bunch of well-known and not-yet-well-known programmers to select medium-sized pieces of code (100-200 lines) that they think are particularly elegant, and spend 2500 words or so explaining why."

I believe Udell's book comments on sharing expertise, through Internet video and screencasting,  are important beyond the field of programming. The influence of expert minds on one another and the potential influence of expert minds on student minds in formation are highly valuable features of our information age. ____JH

"The 600-page tome arrived recently, and as I’ve been reading it I’m struck once again by the theme of narrating the work. Of the chapters I’ve read so far, three are especially vivid examples of that: Karl Fogel’s exegesis of the stream-oriented interface used in Subversion to convey changes across the network, Alberto Savoia’s meditation on the process of software testing, and Lincoln Stein’s sketches (”code stories”) that he writes for himself as he develops a new bioinformatics module.

Although this is a book by programmers and for programmers, the method of narrating the work process is, in principle, much more widely applicable. In practice, it’s something that’s especially easy and natural for programmers to do.

It’s easy because a programmer’s work product — in intermediate and final form — happens to be lines of text that can be printed in a book or published online.

It’s natural because programmers have been embedded for longer than most other professionals in a work process that’s fundamentally enabled by electronic publishing. We’ve been sharing code, and conversations about code, online for decades.

Most work processes don’t lend themselves to the sort of direct capture and literal representation that you see in Beautiful Code. Not yet, anyway. I think that can and will change, though, and I think two emerging forms of media will be powerful agents of change.

One of those forms is Internet video, which enables the capture and sharing of many kinds of physical-world expertise. The other is screencasting, which does the same for virtual-world expertise. Narration of work in these forms won’t be able to be printed in a book. But it will be just as valuable as the narration in Beautiful Code, and for the same reasons. Access to expert minds is just inherently valuable. We’re entering an era in which we’ll be able to access many more — and many different kinds of — expert minds. I’m looking forward to it. Meanwhile, I’m enjoying the access I have now to the 38 minds that Greg and Andy have collected for this book."

The original education plan

After reading last week's column about home school, in which I said that it is more about home than school, one of my students said, 'People will think we don't have school.' We do have school, at any time of the day -- or night -- that a topic of interest presents itself.
