Isolated Tribes Die Shortly After We Meet Them

JazzHarper Inherent bias (351 comments)

We have considerably less data on the isolated tribes that die out before we meet them.

Continued Rise In Autism Diagnoses Puzzles Researchers, Galvanizes Advocates

JazzHarper Re:Or endless 'vaccinations' (558 comments)

Why single out vaccination?

It leads to defendants with deep pockets, more than any of the other hypotheses.

New Information May Narrow Down Malaysian Jet's Path

JazzHarper Re:CNN's Black Hole theory... (227 comments)

OK, other than a simple, "Yes", how do you think Schiavo should have responded? (Let us assume that none of the "experts" on the panel know anything more about black holes than she does, so she's on the spot.)

Silicon Valley Billionaire Takes Out $201 Million Life Insurance Policy

JazzHarper Why is this being made public? (300 comments)

There is no good reason for the financial services company that bundled these policies to be allowed to disclose any of this. I certainly would not use a company that can't keep their mouths shut.

Elon Musk Addresses New Jersey's Tesla Store Ban

JazzHarper Re:Sell them used (229 comments)

Some enterprising individuals are doing exactly that and selling "used" Teslas over list price. There are some buyers who are willing to pay the premium to eliminate the hassles of out-of-state purchase and to avoid the waiting list for a new one. (Yes, the tax on the resale is part of the markup).

Girl's Facebook Post Costs Her Dad $80,000

JazzHarper Re:Teenagers will do stupid things? (387 comments)

Who's the batch of asshats who are reaming her dad out like this anyway? Sounds like it's time to shine a Slash dotlight on 'em.

Nonsense. The school negotiated in good faith and came to an acceptable settlement--quite favorable to the plaintiff, when you consider that he didn't have to prove that they had done anything wrong. It's not their fault that the Snays immediately violated the terms of the settlement.

Ask Slashdot: What Software Can You Not Live Without?

JazzHarper Re:Firefox (531 comments)

Genuine question: people still use SCCS?

I have one data file, started over ten years ago, still under SCCS. The downstream flow uses the metadata. It's not worth changing. The whole flow will be replaced RSN.

Ask Slashdot: How Do You Sort?

JazzHarper Two-pass bucket sort (195 comments)

First by rank (13 buckets) then by suit (4 buckets). I can typically sort a well-shuffled deck of bridge cards in about 85 seconds. That's far from the world record, but significantly faster than most people can do.

3D Maps Reveal a Lead-Laced Ocean

JazzHarper Re:leaded gas (266 comments)

In the 1920's and 30's, "ethyl" (leaded gasoline) was the more expensive grade. By the 1940s, virtually all gasoline contained TEL and manufacturers designed engines with higher compression ratios to take advantage of the fuel. So, by the 1970s, unleaded gasoline required more expensive octane boosters to work in modern engines.

Today, lead additives for vehicle fuel are banned in almost all countries.

UK Government Proposes Rules To Allow 'Three-Parent Embryos'

JazzHarper Re:Stranger than fiction (146 comments)

Under the proposal, the donor of the egg would have no parental rights. That is logical, since mtDNA carries very little information, compared to nuclear DNA.

There is no genetic modification involved so there is no "intellectual property" vested in the DNA of the offspring. From that standpoint, this is no different from conventional in-vitro fertilization.

Star Trek Economics

Not everyone accepts the assumption that "wants" are infinite. They are certainly variable and, in many cases, conditioned.

Good Engineering Managers Just "Don't Exist"

Why the Internet of Things Is More 1876 Than 1995

Ah, lead. Sugar of Lead (lead acetate) has been a popular artificial sweetener since Roman times. If your ancestors were anything more than peasants, they drank it.

Why the Internet of Things Is More 1876 Than 1995

JazzHarper 19th century information technology (142 comments)

My great-grandfather graduated from Milwaukee High School in 1878. He first attended a "normal school" with the intent of becoming a teacher, but found the opportunity to learn stenography and to operate a writing machine. The Scholes & Glidden machine had been developed in Milwaukee in 1874, and the manufacturers set up schools to teach students how to use them. These were very temperamental machines and were tricky to use. (At that time, you could not see the text that had been typed without lifting the platen). His first professional job was as a type-writer for the Winchester Repeating Arms Company in New Haven, Connecticut. Meanwhile, his long-time pen-pal in Chicago had learned how to use the machines at her father's office. They began exchanging letters in type-written form, which must have been considered, for that time, as high-tech as any Internet romance would have been in 1995. They were married in 1883. My great-grandfather and his brother-in-law went into business together, selling the machines across the Midwest.

A Perl Lesson for the Day

JazzHarper JazzHarper writes  |  more than 9 years ago If you have a block of quoted text inside the single-quoting operator q(), a backslash preceding a '(' or ')' (or whatever delimiter characters you have chosen for q()), will be parsed as an escape on that delimiter character. Therefore, you must escape any literal backslash if it appears before '(' or ')'.


#!/usr/bin/perl -w
print q(
This is a test... x(1), x\(2\), x\[3\], x\\(4\\).

The rationale for this undocumented Perl feature is reasonable. The q() operator will ignore balanced pairs of delimiter characters that appear in the enclosed text, but it is sometimes necessary to write text that contains unbalanced delimiters. To make that possible, the q() operator must recognize the escape on its delimiters.


Shiner B.A.S.H

JazzHarper JazzHarper writes  |  more than 9 years ago

Completed my longest ride to date: 93.8 miles,
from Katy to Shiner in exactly 6 hours,
including rest stops. Ride time was 5:10,
avg. speed 18.2 mph.

Weather turned out to be perfect, after a week
of thunderstorms. Most riders were charged up
and in high spirits with the sudden improvement
in the weather. A light breeze out of the north
neither helped nor hindered the westbound riders.

The course was good, except for a 4-mile stretch
west of Wallis where the pavement had been
removed; in other words, GRAVEL. I'm glad that
I had installed Gatorskins last week; a lot of
riders got flats in that stretch. The course
was mostly flat for the first 60 miles, then
turned into rolling hills for the last 33 miles.
Nothing too tough; I stayed in the saddle and
simply downshifted. Never had to use the granny

The post-ride event was rather disappointing.
Free beer, but no place to sit and no shade.
By noon, the temperature had climbed into the
80's, the air was still humid from the previous
days' rainfall and, off the bike, there was
very little breeze. Next year, it would be
nice to have our own tent and chairs (if I
can talk the wife into bringing them).
