how do you think film "disposable" cameras work? If you RTFA, it already says the industry average of reuse for disposable cameras is 5-8 times. They dont just throw them away!
the capital investment tends to be prohibitive for residential applications.
Like its much more energy efficient to use chilled water a/c with a large central cooling tower. Then pump chilled water out to each home for use in chilled water a/c units. Large office and university campuses do this. But, at several million dollars, the investment is just too much for developers.
If I had a list, id put that near the top of horrors that never should've been made.
A bunch of ignorant cavemen 2000 years in the future discover 20th century weapons such as fighter planes and armored vehicles. They somehow still work perfectly fine after 2000 years of sitting dormant. And in 5 days they learn how to pilot them skillfully enough to destroy the vastly superior aliens.
And of course the aliens only vulnerability is radiation, so a nuke destroys their entire atmosphere and planet. Nevermind the cosmic radiation that would continually bombard the planet having no effect...
my university does a summer camp for high school girls. My lab gave them a demo (robots).
Most "CS people" aren't code monkeys. Especially the people they introduce these girls to - remember they're trying to get them interested in CS. So we demo one part flashiness, one part educational. And during my demo I heard a couple whispering "hey he's cute":P
You're thinking of the overall slashdot crowd, which from what I've seen, knows very little about CS in general. Those of us who actually make a difference in the world of computing don't care about KDE, Gnome, Microsoft or whatever little pissing fights slashdotters get themselves into.
uhh just to point out here, the AC also wrote: "I would hope that after 30 years you can do college in a breeze and would know more than some of your professors in some subjects."
but anyway. I'm going to agree with AC, that you likely went to a crap school then. Most major universities dont have many night courses you can earn a non-associates degree from. *shrug*
But whatever. Your posts make you look like an ass at least 30 years younger than you claim.
Alot of countries have done this. In post-WWII japan, Canon's first 35mm camera was a part-for-part copy of a Leica. Its designer disassembled the Leica, sketched each part and had them reproduced locally (and for much cheaper)
Theres all kinds of weirdness regarding the largest SUV's, because the laws were written years ago. Namely, trucks above 6000 lbs are considered 'medium duty'. It never occured to the writers of the laws that individual owners would own one of these things for personal use.
So, in order to stimulate small business, a tax break is given on medium duty trucks.
I doubt many companies care if you can create a turing machine on paper using predicate calculus either. But it's still an important part of computer science.
The difference between a trade school and a university is that the university aims to not only equip you with the knowledge to perform in a job, but to make you a better all around person as well through exposure to other studies, people and ideas.
In no other situation in life will you ever get a chance to experience such a fascinating breadth of humanity in such a period of time. Its a sad shame some people see this as a BAD thing.
I'm in austin, possibly the US's most wireless city, and virtually every cafe and hotspot here with free internet has also done power outlet drops.
Most cafe's dont mind you plugging in. After all, if your visit isnt limited by how long your battery lasts, you're much more likely to buy more of their products.
depends on how close you are. i once lived in utah, and fighter jets often cracked the barrier above. Its like very loud, window rattling, house shaking thunder.
a sonic "boom" isn't a one time event. The shockwave is continuous, so long as the aircraft is flying at supersonic speeds. Therefore, people on the ground for the entire flight corridor will hear/feel the boom as the plane flies overhead.
In fact, no kidding the people at the airport the plane lands at dont hear a boom! Obviously, the plane slows down to subsonic speeds prior to landing. But for everyone in between the takeoff and landing airport that the plane flies over, will be subjected to it.
Hence the reason the concorde was banned from flying over the US, but landing on coastal airports isnt a big deal.
The past several windows releases are named after ski areas in BC canada. Whistler is a ski slope, Longhorn is a saloon at its base. So is the forthcoming Blackcomb, a mountain.
Think how many cars have keyless entry now. Virtually all new models.
How many problems do you hear about people breaking into other peoples cars with radio transmitters? I've heard one or two stories years ago, but with modern frequency hopping schemes its so rare, nobody bothers worrying about it.
yes, it would certainly make labor much less time consuming. a common problem with working on modern automobiles is that in order to get to one part's bolts, you need to remove other parts so you can fit a tool in. And then loosen each individual screw or bolt.
a remote system that could be programmed like "detach right front quarter panel", and then automatically undo the fasteners would save immense amounts of time and labor - which is cheaper in the end for consumers and businesses.
I like the self serve lanes when making a small purchase. At home depot, why should I wait in line behind a guy with a cart full of lumber when all I have is a box of bolts?
Same at the grocery store. Most people use them when they have at most, a carry basket of items.
I work in autonomous robotics research. The robots run wirelessly, but we capture and display mapping data in real time, currently on laptops as we follow them. If we want to direct the machine to a place of interest, we click a position on the map and it drives itself there, avoiding obstacles etc.
The processing and memory requirement for generating these maps from laser and other sensory data is VERY intense. An athlon 2200 would be perfect for the job.
At the moment, walking around with a laptop and following a robot is not only difficult to read, but difficult to manipulate the mouse control, requiring a sort of one armed balancing act and a careful grip.
When locusts swarm and devour everything in their path, uncaring about how this affects whose crops they're eating... I think at times, the analogy is apt.
I don't think this has to do with brazilians as a whole (I know many fine people of Brazil), but rather hormone fed teenagers who've acquired too much new technology in too little time, and don't realize their actions behind a keyboard impact people more than they know. And perhaps don't realize that dealing with it - in both money and time - isn't cheap.
As for fotolog not charging $1 - the reason is fraud makes payment hard, if not impossible for most. Paypal for example requires a credit card, and for brazilians it has to be one of major issuers like visa, mastercard etc. These are very difficult to come by there. Generally only the wealthy have them - certainly not all these 15 and 16 year old kids. Its clear also, that the ratio of people who would actually pay (not many) do not justify lowering the cost. The cost for the site is in substantial american dollars, all paying users should be treated the same.
Of the credit cards that do get used from brazil, the admins have noted a HUGE number of fraudulent ones with stolen numbers get used. Its rampant. Dealing with credit card fraud is hugely time consuming, taking time away from site issues and service.
Which brings us to the new program they launched this week, which was partnering with a major brazilian internet provider to bring better service to brazilians - native language, easier methods of payment, more catered to their cultural needs. Part of the deal of this was non-paying south american users would see a smallish banner at the top of the page. How was this taken? By having hundreds of teenagers 'protest' by posting obscene pictures to group logs and spamming people with offensive gibberish.
and why it annoys people. i'll use a simple analogy.
imagine you have a group meeting about some kind of topic. It all goes well. Then all of a sudden, dozens of others join in, talking in a separate language, often gregariously and completely off topic, and using enough slang that things like babelfish can't even hope to translate it.
Now imagine that all your original on-topic posts to your original members get drowned out by this. And then when you ask the new members to stay on topic, or try to translate their writings, they call you a racist xenophobe, or flood the group with pornography in 'protest'.
Thats whats happening. It happened on fotolog and its happening on orkut.
Do you realize how much it costs to run a website? Especially when the content is chiefly pictures? $5 is token change.
And what do you do when 75% of your users are essentially leeches, who have no intention of donating or paying, slowing it down for those who do? And who don't even use the site for its intended purpose?
And then when the administrators make changes to correct this imbalance, these users flood group fotologs and webforums with garbage, obscene pictures and indecipherable ranting.
And you you go so far as to call the people who complain about this behavior as 'racist', or 'xenophobes'.
Maybe its this gregarious, ridiculous attitude of wanting everything for free, and that everyone ELSE cowtow to your desires is what makes you unpopular. Or as some would say, compared to a plague of locusts.
Don't get me wrong - I have nothing against brazil or its people (the women are especially beautiful), but besides Orkut, theres many other community-esque websites which brazilians tends to invade, in a sense, and attempt to assimilate into their own.
Fotolog.net comes to mind. Originally a website by a handful of new yorkers to be a photo-blog type site, it has exploded with brazilians, mainly teenagers. Its not so much a blog to them, as the vast majority of pictures are crude webcam type self portraits or risque photos they upload, as opposed to the original amateur photographer type envisioned when it was started.
Most words posted on fotolog are written in portuguese. Its a common point of tension among these users and the administrators. Fotolog is hosted in america and its administrators are mostly americans. Therefore, the membership plans which pay for the site and its bandwidth are in american dollars ($5 atm). $5 is alot of money for the average brazilian, and since stolen credit card numbers and fraud is utterly rampant in Brazil, it is very difficult for the brazilian users to become legitimate paying members, and enjoy the benefits thereof.
But what is it about brazil that they tend to 'invade' sites that are clearly not meant to cater to their individual needs, involving language and culture? Why are they not starting their own Orkut, or their own Fotolog, instead choosing to invade an existing site and demanding its administrators cater to them? How can this be remedied?
you could place the cooling tank anywhere, just need extra lengths of tubing.
really what this is is very similar to the way chilled water air conditioning systems work in large office buildings, or building campuses. They have very large cooling towers that 'rain' water down, cooling it. This is then pumped out to individual building a/c units. Though expensive to install, its very energy efficient.
several large diesel vehicles these days (busses, delivery vehicles) are coming equipped with air compressors and tanks. The compressor engages during braking and pumps up the tank. On acceleration, the air is released which helps torque the driveshaft during acceleration, taking the load off the engine.
Just one of many ways (and pretty environmentally friendly) to capture the energy normally lost to heat during braking.

how many billions of barrels of oil would be saved in a year if every car got "only" a 6 mpg increase due to hybridization?
For a first gen hybrid vehicle, thats a damn fine improvement.

Mainly it occurs on high end monitors. And they have sophisticated means built in to combat it.
