Being an engineer is about learning how to solve problems.
'Asking Slashdot' is about getting other people to solve your problems.

If you want to be an engineer, you had better learn how to start solving your own problems, or answering questions like the one you posed, by yourself.

The act of asking a question shows you want to learn, understand that someone else may have the answer and are willing to listen. This is how science and engineering work. To suggest that asking a question is a problem is ludicrous.

And btw, a book and a website are just efficient consolidations of (often but not always) one person's knowledge - it's really no different conceptually than asking a question.

IMHO the guy is a royal jerk. Was it offensive what he did? Yes! Rude? Yes! Immoral? Yes! But it is his right.

The laws in the UK say otherwise. He pleaded guilty at a trial to a criminal charge and has been punished.

  Just because he did it on the internet is irrelevant.

Just because 'the law' takes away a civil right does not make it right or just. Some human rights such as freedom of speech are inalienable.

The whole point of freedom of speech is the freedom to say something that someone else doesn't want heard. Even in North Korea you are 'free' to say how you love the regime. Regulating speech just because it's offensive is repugnant to the values of a free society.

How far would you reference 'the law'. Would it be ok if people got jailed for 18 weeks for saying to someone else that they were a 'dickhead'? Should all rudeness be a criminal offense? Would you say that being locked up for opposing a dictator is just a matter of disobeying the law and being punished? Or would you agree that 'the law' has limits and is not absolute and that it does not always merit being obeyed or being referenced as some kind authority.
ind authority.

When autos drive slower they consume less fuel, which means that not only are those cyclists reducing their own carbon footprint, they are reducing the footprint of the drivers as well.

That depends on the speed. According to the U.S. Department of Energy, most cars’ fuel efficiency peaks at between 35 to 60 mph. [http://www.fueleconomy.gov/feg/driveHabits.shtml]

A car going 10 miles behind a cyclist at 13 mph will consume about 75% more gas than one traversing the same distance at 35 mph. In addition the resulting traffic jam may cause many cars to be delayed further multiplying the effect. That makes cyclists, when they delay traffic, an environmental hazard.

Submission + - Rural broadband cost $7 million per home (forbes.com)

dave562 writes: In an analysis of the effectiveness of the the 2009 stimulus program (American Recovery and Reinvestment Act of 2009 or ARRA), one of the programs that was investigated was the project to bring broadband access to rural America. Some real interesting numbers popped out.

Quoting the article, "Eisenach and Caves looked at three areas that received stimulus funds, in the form of loans and direct grants, to expand broadband access in Southwestern Montana, Northwestern Kansas, and Northeastern Minnesota. The median household income in these areas is between $40,100 and $50,900. The median home prices are between $94,400 and $189,000.

So how much did it cost per unserved household to get them broadband access? A whopping $349,234, or many multiples of household income, and significantly more than the cost of a home itself."

Comment Re:CFL are no savings (Score 1) 990

CFLs have safety issues that its advocates ignore:

1. If individuals are exposed to the light produced by some single-envelope compact fluorescent lamps for long periods of time at distances of less than 20 cm, it could lead to ultraviolet exposures approaching the current workplace limit set to protect workers from skin and retinal damage.

2. Most CFLs contain 3–5 mg of mercury per bulb. Over a period of a few years an average family is likely to break at least 2 or 3 of them. And then they get exposed.

3. If you have kids - god help you. The mercury exposure for them even once is incredibly dangerous.

4. How realistic is it to expect most households to 'properly' recycle them. Most will end up in municipal solid waste and will leak out their toxic content.

5. Some CFLs emit radio frequency radiation that can cause fatigue, dizziness, ringing in the ears, eyestrain and even migraines.

Comment Re:What crime? What misdeeds? (Score 0) 123

So then I guess the following people are all criminals and we certainly shouldn't respect them.

1. George Washington - committed treason. And it's still treason and criminal no matter how unjust the law.
2. Abraham Lincoln - he abrogated the constitution during the civil war.
3. Any black slaves that ran away - they should have just 'stayed' I guess.
4. Alic Paul - and those other suffragists. Cause they should have asked more meekly for freedom and equality.
5. Rosa Parks - she was such a criminal sitting at the front of the bus. I guess all those in the civil rights movement should have been more meek. Cause we know that would have worked.

[Hint: There is a reason to obey the law. And is does not always apply. There would be no modern civilization if no-one had broken the law, no industrial revolution and no Slashdot to post on. I think sometimes that the reasoning part of the cerebral cortex is switched off in some people when they blindly go on about always obeying the law. If the law is enough of an ass, it is the obeying of it that is repulsive and the word criminal in that context is meaningless.]

[Hint 2: Read the declaration of independence:
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another...requires that they should declare the causes which impel them to the separation.
Our Founding fathers stated that when you decide to 'break the law' then it's necessary to explain why and explain that it is justified. If you don't accept this you really cannot be an American - you might as well go back to Britain.]

Comment Re:Global warming is not the big problem (Score 1) 638

Small change now, or big change later ...

I agree that changes need to be made. However little changes in some countries will not do it. Greenhouse gas emissions (including carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, perfluorocarbons and hydroflourocarbons) when taking into account deforestation (land use) mean that China, India, Brazil, Indonesia, Mexico, Iran, South Africa and Saudi Arabia account for approximately 50% of global emissions. Their share and absolute emissions are both rising.

Realistically, speaking limiting carbon emissions lowers GDP and wages and raises unemployment. What is the point of suffering these ailments if the rest of the world does not care? And what about in 10 years time when South America, Africa, the middle east, China and India (please note I am including more countries than I did above) will be responsible for for > 70% of the worlds emissions?

I am not saying that the developed world should do nothing. But unless it can persuade that rest of the world to join, the effort is pointless.

Facebook

Submission + - Social Networks Miss-representation

An anonymous reader writes: In recent months I have noticed a trend on 2 social network sites. Facebook and Linkedin, doing things that are resulting in miss-representation.

Lets look at Facebook first .. how often have you seen a friend invite, to puzzle over why that person is asking to join your network. Then when asking them, only to get the response 'because you sent me a friend request'. This has happened to me 3 times in the last month. Facebook is sending friend requests to my friends, and a message to me saying they have sent a request to me, when we compate notes, neither me or my friend sent any 'requests' at all. Facebook did it automatically. This is miss-representing my chosen network, and making requests without my permission.

With Linkedin I recently updated my profile, I added an additional few words into my work outling. The next day I had an inbox full of people asking what had happened, congratulating me on the new job, wanting to know why I had left. It turns out Linkedin had posted on my news thread and the thread of all of my contacts that I had left the business, causing just a slight bit of panic across the globe. I notified Linkedin and they said nothing can be done ... again automatic miss-representation in my professional network.

I am interested if anybody else on Slashdot has seen either of the above, or if I have just be unfortunate?

I don't dispute that their is some limit that we will approach a limit with respect to computing speed. What I don't see, is evidence for 'economic collapse' as a consequence. Surely there will always be a need for programmers? Maybe more so because efficient programming will yield greater speeds and you won't be able to rely on mediocre quality ones and lazily rely on hardware getting faster. Similarly speaking with 2011 hardware alone we are still are nowhere near reaching the full economic capabilities of the internet - that process could go on for decades alone.

I also would like to see someone suggest some model that would explain how dire economic consequences would ensue if computing speeds stopped advancing with some empirical evidence. Until then - all I hear is scare mongering.

I agree with the comment above and then some. I think Slashdot should cool it when it comes to the third world. When one lacks access to electricity, it's superfluous to talk about electronic devices. And very few people can afford any kind of electronic device - this being very ironic because those societies are very unequal (they have very high ginni coefficients) so that the elites are very wealthy even by Western standards and can easily afford laptops, plasma TVs and gaming devices galore. The problems of the third world revolve around authoritarian, unaccountable, inept and corrupt government. No nifty piece of tech will change that, only revolutions where people demand democratic accountability will - Egypt and Tunisia style.
