Comment Humans are diurnal (Score 4, Insightful) 545

Humans are diurnal (dI-UR-nal).
It means we sleep when it's dark and wake when it's light. (compare nocturnal)

The primary purpose of DST is to keep our scheduled wake time (as determined by school, work, etc) close to sunrise.
Everything else (energy savings! more shopping hours!) is just confusion and wishful thinking.

The controlling factor isn't east-west, it's north-south.
The further north you go, the more sunrise time varies with the seasons, and the more an adjustment like DST helps.

Stuffing the whole country into two time zones is a non-fix for a non-problem.

Submission + - How Your Compiler Can Compromise Application Security (itworld.com)

jfruh writes: Most day-to-day programmers have only a general idea of how compilers transform human-readable code into the machine language that actually powers computers. In an attempt to streamline applications, many compilers actually remove code that it perceives to be undefined or unstable — and, as a research group at MIT has found, in doing so can make applications less secure.

Comment Electronic Sabbath (Score 5, Interesting) 534

When our kids were around 10 and 12 years old, we started observing a Sabbath.
Sundown Saturday to sundown Sunday: no electric lights, radios, TVs, and--especially--no computers.
We'd never observed a sabbath for any religions reason, but we decided to try this,
partly as an experiment, and partly as an attempt to reclaim our lives from electronic media.

The first time we did it, I expected the kids to go ballistic, but they pretty much rolled with it, and it became a regular part of our household.
It did change our rhythms and activities.
We would read or play (card, board, dice) games in the evening.
People went to sleep earlier.

We kept it up for a year or two.
I can't say exactly why we stopped.
The kids got older; life intervened.

Comment Reading is a journey (Score 3, Insightful) 312

For me, reading a book is a journey through its pages.
Not in some metaphorical sense, but in a very literal, tactile, visual sense.
I associate the words in a book with their position on the page,
and the pages with their (approximate) position within the thickness of the book.
It helps me keep track of what I've read, and place words and passages in context of the overall book.

I never thought about any of this until I started reading eBooks and it wasn't there.
An eBook is just one long (long, long, very long) stream of words.
Some eBooks paginate the words for display, but that pagination is typically not stable:
revisit those words another time and they will likely appear on the screen in a different place.
And those pages--such as they are--have no apparent position within any larger structure.

This is OK for a dictionary or a reference manual, where I just look things up.
But for any serious work of non-fiction, it's horribly acontextual: the book just turns into word mush.

I haven't tried reading any fiction eBooks, so I don't know if they would fare any better.

Comment Where are the transactions? (Score 1) 239

I kind of don't get this.
I know that accounting can be complex, but underneath it all there has to be transactions.
Credits.
Debits.
Raw data.
If the numbers on the screen don't look right, the first thing I want to see is the raw data.
They do have the data somewhere, right?
Right???

Comment I used to be proud to be American... (Score 5, Insightful) 330

I used to be proud--really proud--to be American.
We had our problems, sure, but
- we didn't assassinate people
- we didn't torture people
- we hadn't started a major war in 40 years
- the government generally obeyed the law, and when it didn't, someone called them on it.
We could hold ourselves out as a model for other countries.

None of that is true any more.

For a long time, I blamed it all on Bush and the Republicans,
but then we elected Obama and Democrats,
and it hasn't helped.

Now I'm weary and ashamed, and I don't know where to go next, literally or figuratively.

Comment The quality fairy (Score 2) 209

FTA:

As projects surpass one million lines of code, there’s a direct correlation between size and quality for proprietary projects, and an inverse correlation for open source projects.

The article gives numbers: above 1M LOC, defect density increases for open source projects, and decreases for proprietary projects.
Increasing defect density with size is plausible: beyond a certain size, the code base becomes intractable.
Decreasing defect density with size is harder to understand: why should the quality fairy only visit specially big proprietary projects?

Perhaps the way those proprietary projects get into the MLOC range in the first place is with huge tracts of boilerplate, duplicated code, or machine-generated code.
That would inflate up the denominator in the defects/KLOC ratio.
But then that calls the whole defects/KLOC metric into question.
