History: The IBM 3270 series terminals, which predated the PC and with which all the original IBM PC developers were familiar, had separate "Return" (carriage return) and "Enter" (submit form) keys. This architecture minimized precious CPU interrupts. You would fill out an entire form in the terminal, with multiple fields and multiple lines on the peripheral device, then send the whole form to the CPU in one action. This was important in an architecture originally designed for batch processing, and which referred interactive support as the "Time-Sharing Option."

That's a long way from the Unix model, in which every keystroke generated an interrupt, or the PC paradigm, where every key-down and key-up action generated an interrupt.

On my IBM PC keyboard, the word "Enter" is above a "return" symbol. So for sites like Facebook, which require a shift for the "return" function, the non-shift action is the upper marking and the shift action is the lower marking!.

The "occult quality" in this case being the applicability of Zipf's Law, to which the +2 comments so far have exactly one reference. And that reference getting things exactly backwards. Even the graph in the article omits most of the area of the curve which is key to the hypothesis. That is the area in the upper left corner, between the actual values reported for largest banks and their hypothetical position on the Zipf's rule line.

Comment Possible to time yellows below speed limit reqs? (Score 1) 507

According to TFA, the Federal guidelines recommend times based on the posted speed limit or the 85th percentile of actual speed, whichever is greater. Florida is ignoring/removing the "whichever is greater" clause.

In most cases, one can assume that the 85th percentile is greater than the posted limit, in which case the times are based on the posted limit. The ones at risk of a ticket are speeding drivers. But reading the article literally, there is another possibility. If the 85th percentile of actual speed is *less* than the limit (as in a congested area), FDOT is free to time yellow lights according to the 85th percentile, and *below* what the posted speed limit would require. Such an action would put drivers who are otherwise law-abiding at risk for tickets.

It is not surprising that people don't see the ads. The traditional Facebook page (I have not seen Timeline) has four columns, three of which can be entirely ignored.

I find myself developing a unique "blind spot" for every common page with static ad placement. It's hard for me to find the ads even when I want to browse them.

An anecdote from Dr. James C. Cain (former head of section, gastroenterology and internal medicine at Mayo), from about 1981:

A patient came to May Clinic with vague symptoms. One histologist remarked "This guy has weird blood. I've seen it before, but can't remember where." Several days later the histologist came back with the book where he had seen that "weird blood." Leprosy. Mayo didn't get many lepers.

"We were just lucky," said Dr. Cain, "that the histologist remembered the pattern. But imagine what we could do with a computerized search."

Another megabytes the dust.
