One limit on ship size is the "Suezmax" standard, or the largest theoretical ship capable of passing through the Suez Canal, which measures 14,000 TEU. Such a vessel would displace 137,000 metric tons deadweight (DWT), be 400 meters long, more than 50 meters wide, have a draft of nearly 15 metres, and use more than 85 MW (113,987hp) to achieve 25.5 knots,
Which works out to 1/50th of a watt per bulb. Thats such a small number, trying to calculate the cruising energy seems fruitless...
I apologize for the shortness of digital temper, I just quit smoking.
May I suggest restarting? I did a double take on "mandatory" but if you flash into dreams of turning things into hamburger after that something is wrong.
Article gives the size of the glass, and some temps, so it may just be answerable. Googling for: how much energy does it take to manufacture glass, 5 hit (no direct link since its a f***in word doc)
The Recipe For 1 Ton Of Glass (Resources)
1300 Pounds Sand
400 Pound Soda Ash
400 Pounds Limestone
150 Pounds Feldspar
24000 Gallons Water
4400 KWH of Energy
So, 4400 KWH per ton.
How much do the panels weigh?
(.6 m) * (1.1 m) * (.5 cm) * (2 500 (kg / (m^3))) = 8.25 kilograms
(8.25 kilograms) * 4 400 (KWh / ton) = 144 Mj
Apart from making the glass, there is heating the glass, heating the cadmium sulfur and telluride, mining all those chemicals, etc.
Glass specific heat is.84 J/g K.
(.84 (J / g)) * 8.25 kg * 580 = 4 019 400 joules
So I've calculated 148Mj for the glass manufacture and heating. Ignoring the cadmium, sulpher, telluride chemical mining, what do you get out of it?
Remember how I ignored the energy of mining those chemicals? How does the energy compare for mining the GRAMS it would take to deposit a film of telluride compares to the energy for mining TONS of coal.
The answer to what you did ask, at least for the glass + heating, is pretty easy to answer: (148E6 / 85) * s = 480 hours. Less than a month.

For years, I have ordered all of my systems with at least two hard drives. For laptops, I order an additional external drive. Currently, I have a very simple protocol: I use OS X and clone the entire hard drive with operating system to a second hard drive I do the same but with a twist because my company requires encrypted Home Dirs (FileVault). The OP should be using encryption on his laptop drives as well.
1. Every so often -- 4-6 weeks say -- log OUT of my account & run full backup. The backup will include the encrypted disk image.
2. Every few days -- mount the encrypted disk image on the backup & run rsync on my home dir only. I could use SuperDuper for this portion as well.
With FileVault, I can NEVER run a full backup from witin my account, that would leave unencrypted files on the backup disk. This process works, but its not dead simple as backups ought to be. I don't think SuperDuper or any solution I have tried handles FileVault seamlessly enough. I'm hoping the next Mac OS X will... been hoping since FileVault (which is awesome) came out!
Any forced name changes should happen within a few weeks of signup, not months or years into it.
And to those complaining about the editorial, didn't you suspect it was an editorial from the icon and from the lack of a submitters' quoted blurb? Seemed pretty clear to me, which meant reading CmdrTaco's experience was a choice. If it was lame in your opinion, make better choices next time. Don't tell me you read all of Katz' stuff, for instance!
I for one have NO issues with CmdrTaco occasionally using it as a soapbox for personal yet Nerdly matters.
You need more than that. A fixed expiration date hurts very successful programs, and doesn't make belly-up software become open any sooner. Active development, responding to bug reports/feature requests, on the software should extend the expiration.
A lifetime of ten years is common in software, but when a producer company the dot bombs around sometimes the consumer companies really get yanked around. I see this a lot, the ones going down are my competitors
Just use a regular PC and put a handle in the case and on the monitor. Back in the days of 386s, I went on-site with such a set up: a handle screwed into the case, velcro attachments for a keyboard, even a handle screwed into the 14" CRT monitor.
From helping musician-friends haul thier shit around, this seems an adequate solution to me...
There was also a pretty small (Apple Cube-sized) PC case for around $250 that was mentioned a few times on Slashdot... didnt turn anything up in a search tho, sorry.
You're probably planning on working solidly for a couple of weeks or months and coming out with the same product, but cleaner.
Well, consider all the (big or little) features you might like to add, and when you do your rewrite, consider HOW those features would work. That will improve your refactoring and also keep some fun in the project.
I think you should concentrate on improving your processes so that you never have to do this again. So, basically, catch up on all the unit tests and reviews you've never done!
Others talk about tests. That is a valuable practice, but keep it limited to things that are easy to test. If your tests are ten times flakier than the code because its really really hard to write a good test, well, fuckit!
I'd recommend a checkin-review process. Every should be reviewed for:
1. comments-missing-from-unclear-code,
2. violations-of-coding-standard,
3. corner-cases-not-covered.
Those things are pretty easy to discuss with developers, they wont be taken as criticism.
Checkin review REALLY DOES improve your code and it DOESN'T have to be onerous!
Matz: [From perl I borrwed] A lot. Ruby's class library is an object-oriented reorganization of Perl functionality--plus some Smalltalk and Lisp stuff. I used too much I guess. I shouldn't have inherited $_, $&, and the other, ugly style variables.
Ruby is young enough that he could redesign his syntax, with an enthusiastic enough community that he could pull it off.
I think he should stick with one of the {} or do...end styles; eliminate the @ from @member (maybe.member?); generally don't be afraid to make it a MORE beautiful language.

How about bartering? You help with their computer, they do your laundry... or set you up on a date...
