Aug. 18th, 2005 09:05 pmI've spent all week working on homework for one of the Profs at work. We're forcing him to modernize - he has a software package that he had written for him in 1986 to let his students do all their homework on the computer (they each got a floppy with the student side of the program on it), and then every week he'd collect disks and the instructor side would do all the grading and gradebook stuff. XPSP2 killed it.
Now, I'm typing the entire semester's worth of homework into an online package called Desire2Learn. It's really fairly neat in what it can do (multiple choice, true/false, matching, ordering, arithmetic, etc. questions), but it does mean I get to type in 23 problem sets, with supplemental data, but no pictures (yet). I started Tuesday and have two sets left to go.
My typing speed is increasing, and I can keyboard fun things like:
ao² = bT-i·(g(i)²·CoeQ/RT)
because I can't use CSS due to how the environment is set up.
[And yes, I'm enough of a geek to know how to make what looks like html code come up onscreen without being processed as code - and that code's even messier :) ]
I'm waiting to see what the prof says when he sees this table, since he thought it'd be way too much work to type in:
(this table is the answer set for one question - choose the appropriate material from the first column and the property that you selected for from the second, enter the result as a four-digit number).

and get them right on the first try.
It has to be entered as:

I'm waiting to see what the prof says when he sees this table, since he thought it'd be way too much work to type in:

| 65 | Polyamide (Nylon) | 65 | High-strength, high-modulus glass, good chemical resistance, used in composites | |
| 70 | High density polyethylene (HDPE) | 70 | Higher strength, lower melting range than 3004 | |
| 75 | Polyvinyl chloride | 75 | Chemically inert, easily blow-molded, light yet tough, and reasonably strong | |
| 80 | 37PbO, 8K2O, 2Na2O, 53SiO2 glass | 80 | Easily formed by film-blowing, chemically inert, transparent, microwavable | |
| 85 | Aluminum alloy T6061-T6 | 85 | High strength-to-weight ratio, heat treatable to 45ksi tensile strength, good corrosion resistance | |
