Cross-pollinating Web communities

The integration of the Web's diverse communities broadens horizons and technology.

Web projects are integration projects, combining skills from a number of disciplines. Lousy interfaces can obscure brilliant code, and ingeniously engineered back-end systems can still fail when they hit resource limits. “Content” lurks in many guises, requiring support not only from writers and illustrators but from video specialists, game designers, and many more. Marketers have built businesses on the Web, and influence conversations from design to analytics. You don’t have to be a programmer to do great work on the Web. The Web stack is vast.

Web development models include far more than code. Creating great websites and applications demands collaboration among content creators, designers, and programmers. As applications grow larger, supporting them requires adding a cast of people who can help them scale to demand. As projects grow, specialization typically lets people focus on specific aspects of those larger disciplines, supporting networking, databases, template systems, graphics details, and much more.

In some ways, that’s a recipe for fragmentation, and some days the edges are sharp. All of these communities have different priorities, which conflict regularly. Battles over resources sharpen the axes, and memories often linger.

At the same time, though, often even in environments where resources are scarce, different perspectives can reinforce each other or create new possibilities. Sometimes, it’s just because the intersection spaces have been left fallow for a long time, but other times, the combinations themselves create new opportunities. Read more…

The Politics of Recursion

How close to the metal must programmers be?

Recursion predates computers, but computers’ ability to repeat the same task over and over made recursion a common approach to solving complex problems. Factorials might be a classic example of what recursion can do, but recursion enables many more divide-and-conquer approaches, as well as useful approaches to infinite loops.

You may be nodding your head, thinking “sure, but we don’t need to think about that any more.” Or you may be nodding your head, thinking “if only anyone remembered this stuff any more.”

Until a year or so ago I was in the first camp. I knew the basics of recursion, applying it once in a while to calculations and tree-walking, but it didn’t seem central. Loops and queries of various kinds seemed to make recursion a marginal topic. Usually, seeing recursion was a sign for me to move on, marking a story as “more magic than I needed to know about.”

Erlang forced me to learn recursion—well beyond factorials and trees. Single-assignment variables are a stern master, making me rethink most of the logic I’d used for the last thirty years. There were pleasant surprises, too, like the usefulness of infinite loops in Erlang processes. By the end of writing Introducing Erlang, I had my first genuinely fond feelings for recursion.

Now that I think I have a handle on recursion, I’m paying much more attention to it than I used to, and suspecting I’ve crossed a line. It seems like every language has its own dividing line between amateur and expert, but recursion seems to be a line that crosses programming broadly. Languages meant to be approachable go out of their way to make recursion invisible, while languages meant for experts (or those aspiring to be experts) leave recursion in the open.

The rewards of simple code

"Code Simplicity" author Max Kanat-Alexander on the elegance and utility of simple code.

Simple code is born from planning, discipline and grinding work. But as author Max Kanat-Alexander notes in this interview, the benefits of simple code are worth the considerable effort it requires.

Developer Week in Review: Developers are our most important asset?

A good hacker is hard to find, a cheap data center is hard to get to, and the app store model is hard to ignore

An argument for the value of highly productive programmers, datacenters head for the country to save a few bucks, and the app store model seems to be taking over the industry, and not just for mobile.

Developer Week in Review: Adobe raises the white flag on mobile Flash

Adobe immobilized mobile Flash, Eclipse joins the vanity language fad, and one man asks if brainteasers really find good programmers.

Flash isn't dead, but Adobe is checking into hospice options. Eclipse adds another language to the list of ones almost but not exactly like Java. And how do you find good programmers? Probably not with brainteasers.

FOSS isn't always the answer

Proprietary software has its place.

James Turner says the notion that proprietary software is somehow dirty or a corruption of principles ignores the realities of competition, economics, and context.
