If a school does a test on 30 kids, they've spend just $750.
Sure...apart from all the monitors, keyboard, mice, USB hubs, USB cables, extra SD cards, etc. which you'll need to make 30 usable workstations. Add another $150 each - that's another $4500 for the 30 kids.
If there's a price win for public use it's that it's easy/cheap to swap in spare ones when people fill them with malware and/or trash the OS. Send the bad one away to be reformatted.
Sadly, if you have competition they can take your business if spend that bit extra on development to make their application feel more snappy than yours.
...and the answer was that code which is 90% efficient doesn't take any longer to write, it just takes experience.
Code written by fresh-out-of-college-and-heads-full-of-latest-programming-fashions is only going to be 50% efficient (and far more likely to end up on the daily WTF).
(Numbers pull out of my ass but you get the picture...)
Take an expert in DOS interrupts, BIOS minutae, 80386 code optimization, utilizing EMS and XMS memory from 1991 and transport him through time to today.
If you transport him through time, sure. If he's been keeping up to date over those years he's going to kick serious ass compared to today's college kids.
Yep. One data point with no information about speeds, angles, etc. vs. decades of engineering studies. I definitely think 70's cars are safer based on that.
Global warming is 100% wrong, too, based on similar logic. Right?

What value do you place on human life?
Is that an American life or an Afghani life? I think you've avenged 9/11 by about 200:1 so far...and the majority of those were civilians.
Clue: The best way to "save lives" is not by deploying these...
Yep. How come there's still no "#include" in HTML? Anybody with half a brain would have put that in from day one, but noooo.
(Server side includes don't count - they don't work for HTML files stored on my hard disk)
The way I read it the design goal is to get kids excited about computing and get them to want to program it.
How will this excite them more than a normal PC would?
Better to give them a Gameduino (or something like that).
Yep. What's the point in giving them a crippled Linux for learning?
For learning you want something small that gives direct results without having to learn huge operating systems and APIs.
Arduino is about perfect - you type in a few lines of code and see the light flashing. It's real, it's direct. I wish I'd had one way back then.
All connectivity will have to be via USB.
I have a reasonably good command of a martial art...
How come I never saw a headline in a paper which said something like: "Martial Arts master defeats gang of crooks!"
There's a decent percentage of the population practicing martial arts...where's the flaw?
Bad initial design can bog down a program forever, no matter how well you optimize the inner loops.
You're assuming you can't have both.
You can.
Sadly, if you have competition they can take your business if spend that bit extra on development to make their application feel more snappy than yours.
If the code is generally OK then you're right.
If it's bogged down by stupid design decisions then fixing it will take much more than just refactoring a couple of functions.

Compared to the extra mercury produced by the USAs coal fired power stations to power an incandescent, dumping CFLs is not an issue.
... but the US can.
Citation needed.
The overhead for "new Shotgun()" is immense, much better to:
$myShotgun = getShotgunFromCache();

5k would have been heaven when I first started typing Z80 hexadecimal into a computer.
If 'q' is a variable with a short lifespan/scope (eg. one small function) then short is better.
If it's a global variable in a program with thousands of lines ... not so much.

Google is missing out on a whole untapped market with its "safe search" nannying.
I bet there's loads of people who'd pay for an *unsafe* search option.
Free streaming 1080p is a rarity
You want 'good' and 'free' and 'streamed'?
I think I see the flaw in your plan...
Just last week I saw an descendent of the velociraptor walking around.
Crocodiles are so tough they didn't even need to evolve.
Hah! I installed their little app and I won a FREE iPad. It's in the mail as I write this...
https does incur overhead and higher CPU usage on both ends, so it will be slower.
Yeah, my quad-core really bogs down when I use https on a connection which can transfer as much as a few hundred kbytes per second..
He'd just spend the time writing down all the email addresses.
