Fur inhibits sweat-induced cooling, and furry animals generally have other ways to lose heat. In humans, Dr. Jablonski argues, sweat glands evolved as body hair vanished, allowing optimal cooling of the enlarging hominid brain…
This is at least the second time in the last few days I’ve read something about the whole human homeostasis being dependent on losing hair and being a necessary pre-req for a legit brain.
Does it seem like there’s an extraordinary amount of “Hmm…this is our big engineering problem right now…THIS IS HOW NATURE (ESPECIALLY THE BRAIN) WORKS!” Like when distributed systems were getting big in the mass culture, there was all types of Steven Pinker / Daniel Dennett mass-science articles about how that was like the brain. When I was a kid, it was the parallelism / Danny Hillis scene. Now its all heat dissipation, in processors, pocket gadgets, vehicles. I remember reading something about how in olden times, when hydraulics and stuff were just being invented, people wrote books about how the ventricles of the brain were basically hydraulic reservoirs/pumps and the nerves were hydraulic lines that motivated the limbs. If, in a few years, there’s lots are articles about how like bees and ants are really good at solving complex problems with large numbers of simple threads and the coordinating of them is a Hard Problem Elegantly Solved then we’ll know. Maybe I just got Erlang/OTP on the brain from reading that Sam Ruby post.
Unfortunately, it’s never the same 20%. Everybody uses a different set of features. In the last 10 years I have probably heard of dozens of companies who, determined not to learn from each other, tried to release “lite” word processors that only implement 20% of the features. This story is as old as the PC. Most of the time, what happens is that they give their program to a journalist to review, and the journalist reviews it by writing their review using the new word processor, and then the journalist tries to find the “word count” feature which they need because most journalists have precise word count requirements, and it’s not there, because it’s in the “80% that nobody uses,” and the journalist ends up writing a story that attempts to claim simultaneously that lite programs are good, bloat is bad, and I can’t use this damn thing ‘cause it won’t count my words. If I had a dollar for every time this has happened I would be very happy.

The Pages program was originally more of a page-layout program than a writing tool. The new version attempts to fix this imbalance with a less artsy word-processing mode. But the effort is only partly successful. It still de-emphasizes some writer-friendly features. For instance, its auto-correct function is much weaker than Word’s. Another example: In Word, to see how many words your document contains, you just glance at the bottom of the screen. In Pages, you must dig down into a submenu to find the answer. The command for showing invisible formatting marks also is harder to find than in Word.
