Other shows have about the same ratio, though smaller totals.
We can quibble about why more people download lower res versions, but it's clear that people are.
1080p is currently losing to 720p is losing to SD across the board.
Maybe that's because of the file size, but that's just another way of saying 1080p isn't that important to people.
Personally, with my equipment, I can't see a difference between 720p and 1080p, even up close, so I assume that's the reason (some) people don't bother with 1080p.

Just checked a torrent site for Game of Thrones S05E01

Res:624x352, Size:424 MB, Seeds:8622, Leeches:399
Res:720p, Size:1013 MB, Seeds:6849, Leeches:643
Res:1080p, Size:2.66 GB, Seeds:2181, Leeches:171

So it looks like about 10% want 1080p, 40% want 720p, and the remaining 50% are fine with 352p
From that, I'd guess 80% of the market can't tell the difference between 720p and 1080p.

But the main takeaway is that most care more about the story than they do about resolution - the acting isn't any better at 1080p.

Comment: We don't need more mediocre programmers (Score 1) 216

Nobody wants to hire a mediocre programmer.
Forcing everyone to learn programming in school is going to result in a lot more mediocre programmers, and almost no increase in good programmers.

You know what would make a difference?
Getting all the students who have basically no chance of learning to program out of the class, so the rest of us don't have to deal with them.

Adding a write-protect jumper only costs a few cents.
And if you want to keep the convenience of downloadable upgrades, don't install the jumper.
Sure, only a few percent of us would buy a motherboard because the BIOS had the option to add a write protect jumper, but that's still a few percent more sales.
Plus it's a marketable difference - if you've got it and your competitors don't, then you can use scare tactics;
"Unlike our competitors, we care about your computer's health, that's why all our motherboards have physical protections against viruses."

Computers roughly double in power every two years.
That means every two years, malware can be twice as destructive.
Security constantly improves, but it doesn't improve as fast.

Measured as a percentage, the amount of damage being done will go down.
Measured as an absolute, the amount of damage will go up.

Err - no.

That number on the Digikey page isn't lumens per watt (I've no idea what unit mw/W is supposed to be).

If you look at the datasheet that LED is a max of 139 lumens with a forward voltage drop of 2.9 at 350 mA, or slightly less than 140 lumens per watt (under ideal conditions).

By definition there are 683 lumens per watt of radiant power at a wavelength of 555 nm.

The highest announced efficiency LED to date is "only" 303 lumens per watt - http://cree.com/News-and-Events/Cree-News/Press-Releases/2014/March/300LPW-LED-barrier
303/683 = 0.44 or 44%

The best LED I can actually buy is still under 200 lumens per watt, less than 30%

The 4flow, which is pretty close to the best consumer LED light bulb you can get is only 85 lumens per watt.

All much better (efficacy) than a CFL or incandescent, but no where near 48%

By far the most useful extensions are the ones that reduce my "browsing experience"
Things which prevent things from being pushed at me (NoScript, AdBlock)
Things which allow me watch videos at my pace and choice of quality instead of "streaming". (youtube downloader)
And in general things which reduce the number of features I'm forced to contend with.

Any given program will expand to fill available memory.
