Duh, turn up the temperature. Or do you not know the difference between the temp going up and down?

Geoengineered Climate Cooling With Microbubbles

plopez Re:Makes no sense (111 comments)

Well, here is what we do. We get a bunch of poor people, right? Then you give them water skis and hook them up to the back of the ships. They then water ski behind the ship creating the needed bubbles. Climate change reversed and unemployment drops. A win-win!

Drive less. Ban incandescent light bulbs. Recycle more. Eat a little less meat. Turn down the heat. Turn up the AC. All which can be done with existing technology.

NASA's $349 Million Empty Tower

plopez Contralual capture? (200 comments)

I wonder if "contractual capture" had something to do with it. What I mean is, much like the F-35, there was some sort of "poison pill" in the contract that made it impossible to cancel the contract without paying a hefty penalty. Much like firing a CEO these days, where they make more money by getting fired.

Why Didn't Sidecar's Flex Pricing Work?

plopez Re:Supply and demand (190 comments)

"it gets very complex very quickly."
Which is part of the point. There is no quick easy or straight forward explanation. You can look at it from a modeling perspective as just an optimization problem but the number of factors and the fact that many of the factors may have feedback loops that practically speaking appealing to simple curves does not do a good job of explaining the observed phenomenon. The is more going on that simply some n-dimensional saddle point.

"The only assumption is, that information is known eventually."
But the information is not required "eventually" (eventually we are all dead, to mangle a famous quote). It is needed immediately by both buyers and sellers all up and down the supply or service chain.

In terms of the rules of the game, disruptive technology is an important factor. The fundamentally attack pricing structure and I sincerely doubt that any human actor or organization can know what the fall out will be. Which muddies the decision making process. Should we continue to make carriage bodies or should we adapt our business to supply the guy down the road working on that new fangled auto-mobile thing? We can sell a good 10K carriage bodies a year while that geek only sold 200 of his auto-mobiles. The smart money goes with the sure thing, doesn't it?

Should we continue making clips the old way or retool and spend huge sums on replacing all our injection and blow molding equipment? How do we know it is not a fad? How do we get the information we need to make a good market decision. Short answer, you can't. Ever.

Why Didn't Sidecar's Flex Pricing Work?

plopez Re:Supply and demand (190 comments)

There are quite a few assumptions there including the fact that a free market will spring up without government intervention. Actually the post did make a good point in that economics is never that simple. We do not live in an economics 101 universe. Supply and demand curves are unrealistic in that they do not take into account competition, captured markets, shortages of raw material, labor shortages, lack of capital, disruptive technologies, and they assume instant information exchange. Econ 101 is about as realistic as Physics 101 where they reference the 'frictionless plane'.

And don't forget Psychology. Despite all the fancy equations and obscure terminology Econ. is essentially a Social Science. A sloppy and unethical one at that.

It all comes down to this from the article "But I think the simpler answer is that the free market is just not the meritocracy that people think it is".

Google Suggests Separating Students With 'Some CS Knowledge' From Novices

plopez Footnote (307 comments)

[1] I actually have the same question about student athletes and folks in a specific discipline on a near by campus where they live in the same dorm; really condos; have their own library or study area, their own dining areas (no longer cafeterias, now called food courts), rec centers etc. I do not think that is condusive to getting a good education.

Google Suggests Separating Students With 'Some CS Knowledge' From Novices

plopez Segregation (307 comments)

You can look at it in two ways, either against those with prior experience or a rapid learning rate or against those with little experience or a slower learning rate. Why are we speaking about putting people into ghettos[1]?

In any event there are two important questions that come to mind:
1) What happens when the AP twits have to work in a heterogeneous environment? Will they have the "soft skills" they need to function in such a work place?

2) There is the question of whether online courses are even effective. We could be holding people back. See http://ccrc.tc.columbia.edu/pu...

California's Hydrogen Highway Adds Another Station

plopez Re:I suppose this is a good thing... (87 comments)

I don't think t make sense in any way. The large carbon foot print and the fact it does nothing to wean us off of hydrocarbons makes t a bad idea. It makes more sense to burn natural gas. I cuts out middle man for lower costs and pollution. And a better developed infrastructure.

Is Agile the new silver bullet?

plopez plopez writes  |  about a year and a half ago

plopez (54068) writes "Agile is becoming, at least in my experience, the latest in a long line of silver bullets. Questions are arising about it applicability and articles are appearing criticizing the approach. A practice often considered best for smaller projects is being pressed into large corporate projects with far flung team members. The spawns articles such as the one recently submitted on Slashdot and even CIO.com is getting into the act: http://www.cio.com/article/734338/Why_Agile_Isn_t_Working_Bringing_Common_Sense_to_Agile_Principles

So what are the limitations of the Agile process? Is it over sold? What can be done to preserve the best parts of the approach in the face of what may be growing backlash?"

The Isolation of Academia and the Private Sector

plopez plopez writes  |  more than 3 years ago

plopez writes "The ask Slashdot
recent posting "Ask Slashdot: Successful software from academia" asked a good question but I think also missed a larger issue.

The programming I have seen in Academia has been poor, probably worse than the private sector. OOP seems to be unheard of and is often taught by those who only heard of it a few weeks before they were required to teach the class. Ditto with Design Patterns, UML, unit testing, Agile Development, and the hard lessons from private sector death marches. The Application Developers in Academia are often poorly taught and undisciplines, more so than what I have seen in the private sector.

In addition outside of a few areas such as games, databases, and graphics; learning from Academia often doesn't make it into the mainstream. E.g. algorithm analysis should be a basic given for any working programmer, I know I did it when working as a programmer. But when I tried to explain why a bubble sort was a bad idea I was often met with blank stares. Or why using a DOM XML parser on large data sets instead of a SAX based parser was a bad idea. Or how to hack a SAX parser when needed, which involves tree searches and push-down stacks. Both push-down stacks and tree searches should be Sophomore level programming and in every programmers toolbox, even if only to assess whether a library based on these principles is a reasonable solution. Or self-referential programming, which is often skirting on the edges of AI (and in fact what some Design Patterns may be approaching). Another cool thing coming from Academia but yet seemingly unheard of is time-oriented databases (see Snodgrass who works at the University of Arizona if you are interested, there are some bizarre things that can happen if time is mishandled in databases).

The upshot is that Academia and the rest of the world seem to be isolated from each other. There is a wealth of experience in the private sector that doesn't seem to make it into Academia and vice versa. If I am wrong please correct me. And if you have ideas how to fix the problem please share them."

Ask slash:What is the best copyright for a thesis?

plopez plopez writes  |  more than 3 years ago

plopez writes "I am wrapping up an MS. In the past I have had problems getting copies of others' works due to lack of copyright notices on their thesis or dissertation. I don't want that happen to me. I know the joke is "No one will ever read your thesis", but in the slim chance it is useful to others I don't want them to be required to hunt me down for a release. Basically I want to say: "Copyright is released as long as this work or excerpts is properly attributed. Also, any published excerpts cannot be copyrighted by other parties, nor can the original work in its entirety.

Is this good enough? I don't want to encumber legitimate uses of the work but I also don't want some pirate coming along and stealing it out of public domain. Is public domain good enough? Or does it allow the work to be restricted by commercial interests? I know of copyleft, but copyleft is a family of copyright notices and I am unsure which one is right for my intent.

Please help. Stay on topic, don't respond to ACs who are trolling (I never do), and be polite.

TIA""

Why am I here?

plopez plopez writes  |  more than 4 years ago

How many years of my life have I wasted on slashdot. I could have done something more satisfying, like drinking or cultivating a heroin habit.

I seem to have not only friends but fans on this site. Why? I'm finding things getting weirder, but I guess that makes life more interesting.
