Meh Try flying Mozambique airlines between Johannesburg and Maputo. The pilots REALLY are ex fighter pilots. Besides the fact that they use(d) old Fokker 200's (you can see loose bolts rattling around under the flaps, swear to god), the pilots seemed to have a challenge in how little runway they used to stop the plane. The amount of times I left a face imprint on the seatback in frint of me.............
Absolutely For a good long while I specialised in performance testing of banking engines. Nice solid contracting income. I made a good living, not by being brilliant, but by always being right. If this meant I had to do 3x the work of the next guy to be sure of my facts, I did it (often at nominal extra charge).
Doing 11th hour performance testing also means that you are always involved in politics, and very rarely in a positive way. My first line in virtually every take-on and every final debrief meeting was this: "I make friends over the weekends, I'm here to tell you the bad news, before your customers do. If you dont want this, tell me to leave now (at take ons) or dont hire me again".
I have VERY few developer or admin friends. I have MANY more management friends / colleagues where a huge amount of mutual respect is present.
Thems the breaks, in the middle ages they would pour boiling oil over carriers of bad news...

Does the earth emit ANY form of radiation? If so its thermodynamic potential cannot remain the same. Since the earth emits some energy into space, its clearly not a closed system.
Since you are unable to address any of the other points, you win the fucktard prize of the week.
* Probably because you never put any water in, either that or your single lonely braincell has leaked out and managed to clog the drain.
While your physics MAY be good, I'm afraid your reading comprehension is less so. You are clearly referring to Kelvins third formulation: "It is impossible to convert heat completely into work."
So granted, SOME of the other forms of energy (mostly kinetic in my example) will by definition be lost as heat. Since NOT 100% is lost as heat (Since that would be a pretty fucking useless power plant), you grant that SOME of that energy previously in the form of heat has become a different form of energy? (electricity, light, sound waves, I don't give a shit).
Since you claim to know the second law, I suppose you are aware of Clausius' heat formulation: "Heat cannot spontaneously flow from a material at lower temperature to a material at higher temperature." The surface of the earth is ALREADY being heated (possibly more efficiently than via all this state change and wastage) by the higher temperatures of the lower crust and below.
The original poster's contention was that it would make it "much warmer" on the surface. This assumes: a) That the temperature of the surface is not already increased to the same extant as waste and ultimateley produced heat from the generated energy. b) That the amount of heat unintentionally generated would be enough to make an LARGE (i.e much, many, big amount, lots, not a little bit at all) difference, even taking into account the localised drop in temperature at the point of geothermal electricity generation.
The enthalpy of the planet cannot remain the same, since the planet is NOT a closed system, go back to undergrad class sonny. That is not the question under debate.
* Penultimate hint: Learn to read. * Final hint: You're not the only physicist on the board, but you fail to rate as one of the logicians.
Oh for Chrissakes, are you being dense on purpose? By pumping water to a point underneath the crust you are heating the water (and cooling that point by the same amount). This happens because that point is warmer than the water (and since the water probably comes from the surface, yes warmer than the surface, that has fuckall to do with the argument).
This means that energy is transferred to the water, energy is lost by the point underneath the crust in the form of cooling (molecular kinetic energy lost). That energy is tranferred to the water to an equivalent amount, in both the forms of molecular kinetic energy (heat) as well as the energy required for phase change (water to steam).
Since using a turbine was suggested, the fact that steam (water endowed with energy enough to undergo phase change) tends to rise is used to spin the blades of said turbine. This motion is then used to generate electricity by means of induced electron flow. (Stator, electromagnets, whatever the generator setup connected to turbine)
SO:
HEAT -> Phase change -> kinetic energy -> electricity.
The crust, and every damn thing currently being heated by that point will cool down to a corresponding amount to the energy generated.
Nope, no violations here officer. The amount of cooling of the crust would equate (minus inefficiencies) to electricity produced. This electricity would be converted to other forms of energy (and ultimately, more heat, I suspect).
Total overall energy in closed system would therefore remain constant, and thermodynamic laws are satisifed.
Seconded Of about 12 machines of different architectures that I own and that run linux, a grand total of 1 (my work laptop) dual boots and uses GRUB. Every other machine only runs linux, and only uses lilo (or silo, or milo).
Nope You are all missing the point. The greatest benefit of internet to the third world has nothing to do with getting farmers the latest alfafa prices, and everything to do with creating an unrestricted, uncensored source of information.
This information can (and should ) be pertaining specifically to local and regional government, and their reputation in international circles. While this information is controlled by corrupt governments, we have situations like in Zimbabwe where the local population truly believes that the country's financial ruin, and the possibility of impending widescale famine is due to western leaders being in league with Satan, as opposed to their crackpot dictator indirectly in charge of the last remaining vestiges of media being as crazy as a red assed baboon.
(This does of course not preclude the possibility of a first world 'elected' president also being as crazy as same aforementioned baboon, and also -according to some- controlling most of the media, and the lesser intelligent segment of the population... but thats another argument)
Dude, seriously, two typos should not an invalid post make. While I'm not saying that I'm a high and mighty anything, do you actually have any input to the topic under discussion?
OK OK, "learning" misspell was unforgivable. Mea culpa, thanks for the correction. "With" misspell was a typo, since I typed that on a PDA keyboard, so that's my excuse and I'm sticking with it. "De-steepened" is not a word anyway, so I am curious to hear how you justify criticising my spelling.
NOW.
I assume you were able to understand the posting well enough to criticise it. Since I make no claim to the merchantability, usability or saleability of my posting, where the hell do you get off judging whether it was good enough to read, since by reading it, you clearly understood the message contained therein.
Except for coming over as an annoying prat, was there any hidden purpose in your response relating to the topic under discussion. If not, I'm sure there is a classification that applies to your post.
The problem wuth VB as a language is exactly the same as Windows as a server platform. What Microsoft has done is de-steepened (not a word, I know) the lurning curve to such an extent that even the shittiest of coders (and admins, for Windows) can push a product 'just barely good enough' out the door.
Once the problem truly becomes hard, these coders (and admins) are left in a a complete state of frustrated confusion, since it was SO easy to get to this point WHY cant they seem to get this block of code (or this insecure web server) sorted.
The dumbing down of IT has resulted in an unfortunately large percentage of dumb IT people.
Thanks Microsoft! Your wizz bang, make the language sell wizards that code your app by itself has helped only your pocket-books... as expected.
And you've hit the nail squarely on the head. Making a living testing and hardening servers has taught me 2 things: 1) Securing a *nix box is EASIER than securing a Windows box because of the inherent security model (OS built to restrict and separate users) 2) MUCH MUCH MUCH (x 10 000) more importantly, the learning curve for a Windows administrator is simply too shallow. Windows' ease of use makes it way too easy to set up a web server, or a mail server (or god-forbid, a media streaming server, if a client asks for this, RUN, don't walk) without having to get a grasp on the fundamentals of what that service's impact is on security. Show me someone that can set up sendmail to work properly, and I guarantee you that the implementation has been thought out 1 000 better than some prat installing Windows SMTP from the add/remove dialog. VHOSTS in Apache, while significantly simpler to set up than 5 years ago, makes a similar counterpoint to IIS.
It's just too easy to be a (shitty) Windows admin, pushing out 'good enough' solutions, as opposed to someone that has had to figure out how things really work.
Ummmm RTFA.... Unless the original poster's little girl was actually in her mid twenties and 'schoolyard bully' is a euphemism for an overzealous member of the board, methinks you need to get you head out you ass.
This does lead us to conclude that international relations between countries resemble the schoolyard more than the boardroom, but I digress.....
But sure, the next time you are being mugged, let me know how sitting down and having a reasonable debate with the mugger on the merits of the current socioplotical climate and its impact on the lowest percentile earners works out for you....
