Ok, so this is not statistically meaningful, but from a sample size of two students (well, my kids) here:

The elder got the question in two seconds and filled the parenthesis with a 7 within 5. No help.
The younger couldn't "get" the question, even with some prompting, and filled the parenthesis with 11.

They are eight and six years' old; neither are especially mathematically talented, but put in more than average effort according to their teachers on that subject.
Both go to the local (non-private average-sized) school.
I'd think (i.e., place a small bet on it) around half the 7-to-9 year olds at that school would be able to "do" this problem correctly.

How old are these "middle grade students" in the study? This kind of age? I can't see it in TFA.

Agreed, you AC, you.

The above is corrected version courtesy of the cup of v. strong coffee on my desk, and is bought to you by the number 42 and the letter fark.

I'm sorry, but this is just wrong. The higher the bandwidth of your signal, the more data (symbols viz. Nyquist) can be sent.

If one were to use Single Side Band transmission, for example, the carrier could be at 76Hz and, using simple Frequency Modulation this could be extended towards say 60GHz, giving, well a Freeking Large symbol rate.

Of course, doing this would interfere with every single electronic and probably every single electric item such as I dunno, a 60Hz light bulb. But it could be done

(You'll need to grep wikipedia for thing I should have linked to. Tired. Very tired)

Thanks fish, so long, or something.

Same problem recently: a 21 year-old 20MHz 80286 with a load of Cad files that suddenly became important. The machine had been in storage for c. 15 years! ST-506 drive with an "One-to-One Interleaving ISA card", a 1.2MB 5.25" floppy (not working) and two serial ports (one blown). Aargh.
Suprisingly, it booted fine, once the backup battery was fixed.

This is - paraphrasing - what you could do based on what worked for me:

If the Xenix machine boots, and the serial port works, make a null-modem cable and connect the Xenix machine to a PC with a serial port. Then use Kermit http://www.columbia.edu/kermit/case16.html to move whatever you want over. You'll need to do the Kermit boot thing on the Xenix box.

Otherwise, as other posters have said, dd is your man, once you've connected the drive to your IDE controller.

N.B., are you sure it is IDE and not ST-506. 10MB is awfully small for an IDE drive...)

Best of luck!

Tsk.

Best PDP-11 look-alike. No end of programmers.
Programming model a dream, vs.....
IMHO, the 8086 (8088, if you really like 8-bit busses) was Not Really Good.
"Short" addressing, vs., "Long", vs. ?"Extended". Bwahararahahahahahah.

A Z80 could do same as "paged mode" (but slowwwwer) by a quick poke to the e.g., 74LS322. 12 years' earlier, too.

Intel iAPX 432: Fantabulious,
NOT.

If IIRC, you are indeed Sir, right.

I'm going to agree with you here: the plots look like the kind of thing that a school kid could write for (say) an Acorn Atom c. 1982.

Bhut, I'd be pleased if a FS project I was deeply involved in got to 10k commits.

Beauty is in the eye of the beholder.

Per your contrition, 1,$s/kW/W/g surely.

Bhutt it's easily done; I did almost the same myself in an important exam at 18:

"What is the velocity of the hour hand of the clock?"

"Easy" I thought: 2PiRadians/hour. Wrote it.

Then I exited said exam and immediately thought:
"F*ck!"

[it's 2PiRadians/12hours BTW]

WGAF today: it's Comic Relief Day here

250kW/s/litre is 250x10^3/3600 which is 69.4W/hour.

Which seems about right.

Bad form to reply to self, but anyhow...

/Informative/, to me, means "provides useful information". It should not mean /Opinion/, he said, passing an opinion.

Interesting to see what this post gets tagged then.

cash-=2*p;

The GP is correct: Power is measured in watts, and "one horsepower" is 740-ish of them.

Current, on the other hand, is measured in amps.

You could have said "[] cleaners' motors draw a number of amps, and here in the US with our 120v mains, you'd need at least a 10amp motor..."

But, you cannot say "[] cleaners are rated in Amps of power". Makes no sense.

Why the parent is rated Informative is anyone's guess.

Having spent 10k+ hours programming, I am now far from a programming genius. The more you gnow...
