The whole "Don't Be Evil" thing has never been about actions or behaviour. It has always been about impression. The full line should read: Don't be perceived as evil.

I usually ask my server what their name is. It would be rude to try to name them myself. Unless they do something to upset me, I also try to leave a good tip.

I'm all for solar and wind evergy, but they cannot replace hydroelectric, fossil fuel, and nuclear generating facilities. They can only suplement them. The primary challenges, beyond cost, are as follows:

1. Supply cannot be adjusted to demand. My understanding is that wind is especially bad for this, as it is windiest in the evenings, after major industrial energy consumers have closed down for the day. We currently have very few options for storing generated power for later use. Batteries and capacitors are nowhere near ready for this task. There are a few hydroelectric stations that pump water up in to large resevoirs during the night for use during the daytime surge in demand. The areas where wind and solar are most effective, there is often little in the way of hills and water, making resevoir-based energy storage impractical. Also, resevoir storage requires the costly construction of a resevoir, pumps, and an entire hydroelectic generating station.

You might think that wind and solar could be used to provide baseline power, while "traditional" coal and nuclear adjust to peaks. Unfortunately, this is only partially true. Many PLWR and BLWR nuclear designs (almost all American designed plants are one of these two types) are not able to idle. This means that if the load on the plant falls beyond a certain level, the plant must perform a full shutdown or risk heat damage. This might not sound too badm but these same plants take at least a full week to restart, and require lots of electricity to do so.

Hydro is able to adjust it's output very rapidly, however there are only so many locations where hydroelectric dams can be installed. People often cite massive untapped locations far away from existing populations. Excellent! Now all we need to do is build costly and inefficient long-distance transmission lines to carry that power to where it will be useful.

Coal is also able to adjust output quickly, but, well... it's coal.

2. The second problem is that of dealing with a phenomenon called "reactive power". This is when voltage and current on an A/C line are thrown out of phase. Ideally, as voltage reaches it's peak, so does current. If you're voltage and current get thrown more than a few degrees off, you're home outlet may still be delivering 100 volts and 15 amps, but not really either at the same time. First you get 110 volts, but low amps, followed quickly my undervoltage and full 15 amps. This means that the usefull power on the line is diminnished.

Reactive power occurs as a result of inductive loads such as electric motors and transformers. As the coils in the motors rotate past the magnets, or the electric field rises and falls in a transformer, these devices become generators. This "reactive" generation is always slightly out of phase with the input power, and so the power that they feed back on to the grid causes voltage and current on the grid to skew slightly. Multiply this effect by the number of inductive loads on the grid (refridgerators, industrial equipment, televisions) and you can start to have a real problem.

Electrical generation sources that employ large turbines are able to adjust the magnets inside their generators to help counteract reactive power by producing power that is out of phase, but in the opposite direction.

Traditional wind turbines are unable to do this, though I believe some newer designes can, at least to some degree. Solid state inverters such as are used to interface solar cells to the grid are not able to to this at all, and so there is a very real limit to their usefulness on the current power grid.

Anyhow, I'm all for wind and solar. I just don't think they are able to provide a complete solution. Nuclear seems to be the way to go, but it must be done right. The Canadian Advanced Candu Reactors look like a viable option. They are designed such that they cannot melt down, produce relatively safe waste, and are capable of idling quite safely. I don't know why everyone insists on using dangerous PHWR designs.

Muon Suite isn't quite a "package manager" so much as it is a graphical interface to apt/dpkg.

Dear Slashdot,

I'd like to become an expert in a field in which I have no experience.

It takes many years for most of the folks working in this field to gain the knowledge required to be effective, but I am very, very smart. So much smarter than most people, infact, that it shouldn't take me more than a month or two to get a firm gasp on things.

There's just one small problem that is preventing me from teaching myself everything that I need to know to be able to do my job well. See, I'm not smart enough to know how to even begin to teach myself anything about this field. I'm sure if someone could just point me in the right direction, I'm quite sure that I'll be able to make sense of things.

Also, which vendors provide "easy" buttons on their gear?

Please advise.

I've had a hotmail account since '94, well before Microsoft purchased them. I used it for everything. It had all sort of amazing stuff in it, letters between myself and some of my first girlfriends, things I really rather treasured. I was quite a fan of Hotmail. Even when Gmail was released, I didn't think I had much use for it. Hotmail did everything I needed.

Until one day in '04, when I logged in after having taken a bit of a break from the online world. It was the first time I'd logged in to my Hotmail in a month, so I expected there to be quite a lot of mail. There were plenty of new messages, but all of my old email was gone!!!!

I freaked out for a while, then read through the "terms of service" or whatever they were calling it at the time. Seems they had silently implemented a policy whereby they delete ALL of your email if you fail to log in for 30 days. Ten years worth of email GONE!!

I suppose they were trying to provide incentives for people to log in to their Hotmail more regularly, but it all it motivated me to do was to open a Gmail account immediately.

Sure, it was a free service with no guarantees. Perhaps I should have been making backups of my precious emails. Thing is, this was not something they did by mistake. This was a policy that they willfully implemented. They chose to punish their subscribers. I don't get it.

Microsoft sucks.

It's been years, but I believe you can enumerate shares with "net show \\server"
