...the profound impact of Computer Aided Design in Drafting...
CAD is extremely useful when designs can be directly exported to machines that do the work. For most other applications the benefits of adopting CAD is still a bit questionable (unless the job simply requires copying a previous project and changing title blocks for the new customer).
One reason for this is that we now have school-certified, generic "CAD operators" as opposed to "OTJ-trained, discipline-specific draftsmen".
The relatively slow adoption of 3D CAD for many applications is illustrative; 3D is great for visualization and wows the client, but when 2D drawings still must be "blue"printed for the blue-collar crowd (who often know better than the whiz-bang CAD designers) you're still dealing with the same old paper reference materials.
A: The short answer is; to do a hands on site survey to photograph and document all 1221 USHCN climate stations in the USA. No photographic database of these stations existed, hence the need for this project. See the about page which outlines the goals.
A Software Engineer, a Hardware Engineer and a Departmental Manager were on their way to a meeting in Switzerland. They were driving down a steep mountain road when suddenly the brakes on their car failed. The car careened almost out of control down the road, bouncing off the crash barriers, until it miraculously ground to a halt scraping along the mountainside. The car's occupants, shaken but unhurt, now had a problem: they were stuck halfway down a mountain in a car with no brakes. What were they to do?
"I know," said the Departmental Manager, "Let's have a meeting, propose a Vision, formulate a Mission Statement, define some Goals, and by a process of Continuous Improvement find a solution to the Critical Problems, and we can be on our way."
"No, no," said the Hardware Engineer, "That will take far too long, and besides, that method has never worked before. I've got my Swiss Army knife with me, and in no time at all I can strip down the car's braking system, isolate the fault, fix it, and we can be on our way."
"Well," said the Software Engineer, "before we do anything, I think we should push the car back up the road and see if it happens again."
For some reason I've always thought that the "you insensitive clod" phrase was from Mad Magazine, but Wikipedia says that it's from Calvin and Hobbes. Am I imagining things again?
Sulphur being shipped east via train from Alberta's oil-extraction facilities. Photo taken from the Calgary Tower; the total length of the train was about 50% longer that what's in the picture.
My Canon SD630's rechargeable battery seems to last a fairly long time and it has to power a 3" LCD screen and the mechanical movement of the 3x zoom lens. Is a "feature-laden" cell phone much more demanding than that?
I've seen detailed instructions in some bathrooms on how to wash hands after "using the facilities". Apparently, you're supposed to wash your hands ("vigorously" for some arbitrarily-determined period of seconds), leave the sink's faucet running, dry the hands with paper towels and then use the paper towels as a shield to turn off the faucet/flush the toilet.
Personally, I just prefer to not piss and/or shit all over my hands when going poopy or pee-pee.
No one gets anything out of believing in global warming.
Incorrect; most get a feel-good sensation and the perceived safety of knowing that going along with the mainstream won't cause unpleasant situations when meeting up with a true believer in an otherwise pleasant social situation.
You don't think that there are billions of dollars at stake for companies that will be manufacturing the devices needed for Right-Now mitigation of "dangerous emissions" and fuzzily-defined expectations? Do you know what design criteria is?
In my opinion, the concept of the ability to trade pollution "credits" is clearly just shifting money around and will do nothing for the overall current global crisis.
But then again, what else would you expect from a denier like myself? I'm obviously twisting words and come from the non-scientific, politically-motivated side of the issue.
When I get points I often drop down to +3/+4 comments and mod there. I don't recall ever modding something down (I perceive that as negativism). If a +3 post is interesting enough and has good replies I'll mod up 0, 1 or 2's (but very rarely ACs). Just my experience.
Maybe Taco could open up a thread for current/past moderators about how it all works. It'd probably be the longest thread ever up until a mini-Malda pops out of Kathleen.
""The hope I have here is simply summed up: To stir your imagination, awaken your interest, arouse your curiosity, enliven your spirit - all with the purpose of bringing you to ask, as young Maxwell put it, "What's the go of it?" - or, as Kepler had it, "why things are as they are and not otherwise". Or, more simply in my own phrase, why is it so?""
Unfortunately, the video supposedly available doesn't seem to work.
Yeah, no asphalt near LOX, eh? Facilities I've seen had SS angle iron suspended underneath the piping so as to drain the condensed air to a "safe" location. Sparking clothing is also a no-no.
True. For cryogenic production, perlite is used but for bulk LH2 storage it's an inner SS (I forget which grade) vessel surrounded by a carbon steel shell. In between the two is reflective material and vacuum. Aerogel is interesting but I don't work in cryo anymore, so I can't really comment about that.
Neat cryo trivia: cold liquids will condense water vapour out of the air, but an exposed pipe that conveys liquid hydrogen will *liquefy the surrounding air*, leaving a mixed pool of liquid nitrogen and oxygen on the ground.

HP Laserjets wouldn't have such horrible math if they just used RPN to do the calculations. Post-Carly HP: WTF is RPN!?
...today "we" have over 7000 stations that measure land temperatures...
Is this maybe relevant to the discussion?

Innovators usually want to forge ahead because they like innovating, damn the torpedoes.
The non-innovators who stand to financially benefit from the innovation need time to figure out who's going to get what out of it.

...but were cock-blocked...
Because they were prevented from penetrating the open, soft(ware) market hole?

They apparently start at CAN $17,590 (vs. US $14,000) while the exchange rate is at .94. Where does the extra ~$2500 come from, all duty/customs?
You can't get much better than old HP calculators for tactile feel.

Eff that, I'm more worried about what kind of impact this new technology might possibly have on global climate change.

Maybe there could be canned laughter also.
It's a quote from Futurama.
Global Warming as Religion and not Science
When you do things right, people won't be sure you've done anything at all.
When I get points I often drop down to +3/+4 comments and mod there. I don't recall ever modding something down (I perceive that as negativism). If a +3 post is interesting enough and has good replies I'll mod up 0, 1 or 2's (but very rarely ACs). Just my experience.

Not really. Take a brick of Jell-O. Push one end. You'll move it, but it will distort in shape, compress, wobble, send waves, etc.
Boobs also act similarly. Or so I've heard.
Eureka, that's it! Boobie physics! What else could better attract young males to science and fluid dynamics?

Excellent point.
