    Do I think I'm unethical? I'm willing to bet 90%+ of the people who actually saw the technique and applied to HBS in Round 2 (the round currently awaiting decisions) tried it.

    You don't get it, do you? I'd be willing to bet that a few Enron ex-executives tried to use the "everybody else is doing it..." non-justification, too. Although I don't think peeking at one's admission status is a huge sin, the fact is that you knowingly broke the rules to take advantage of a technical error for personal gain. That's pretty much a textbook example of an ethics violation.

    Personally, if I were you I'd be hoping that HBS doesn't quietly send a list of the offenders around to other schools' admission offices to let them know what they may be getting.

    I'm going to turn lemons into lemonade, though. I'll be selling t-shirts to commemorate the saga of the HBS 119. Buy one, and put me through b-school.

    No thanks, but I'd be likely to chip in for a philosophy and ethics class or two.

However, there's a lot you can do to limit the amount of junk that even makes it that far into your system:
    1. Filter the HELO messages. If the sender says "HELO yourownname.example.com", then it's lying and you can safely reject the connection.
    2. Don't be overly picky about reverse DNS lookups, but do check that the domain of the From: address is resolvable. After all, what's the point of getting mail from "spew@nonexistentdomain.com" if you can't reply to them?
    3. Selective DNS blacklists. Do your homework and find a couple that are picky about what they add. Remember: false negatives are much better than false positives!

    You can halve the MTBF on your hard drive just by spinning it down at night and on weekends.

    I think you meant "double". I hope.

    As long as that's the only time you spin it down, sure. But note that most drives have a finite (and quite small) rated number of powercycles; I think a Maxtor I had recently was rated for around 10,000. Say you set aggressive PM on a machine that's actually used fairly frequently, and it ends up cycling 20 times per day. Great - now you have an estimated life of about 500 days. I'm reasonably sure (although I haven't done the math) that just leaving the drive running will actually save money on the replacement cost versus electrical savings, and I'm certain it'll save environmental costs.

    Anyway, I'm not harshin' on ya. It was a rant directed at stupid behavior I see at the office everyday. :)

  8. Acceleration facts on How Are You Conserving Energy? · · Score: 1
    OK, now that you've stated the fallacy:

    In nearly every conceivable circumstance, you will find that adjusting your velocity by means of the steering wheel and the brake will take you out of danger much faster than the accelerator.

    ...we can all agree on the facts: there are many, many instances where increasing your forward velocity rapidly is the only safe course of action. The most common is the case where you find yourself merging onto a busy highway from an on-ramp or other start-from-a-standstill position. You need to be ably to quickly match your speed to that of the empty spot you're driving next to. If you can't, you'll probably find yourself choosing between 1) driving past the end of the merge lane in a frantic attempt to accelerate, or 2) slamming on your brakes when you realize it isn't going to happen.

    Gentle acceleration and slow stops are worthy ideals to shoot for, but if you think that crippling a car's ability to interact with its environment is a good idea, then you need to get out of the Traffic Theory classroom and onto the road. Just don't do it near where I live, OK?

    I can't think of a reasonable mechanism that can make you see optical interference between a CRT and a fluorescent tube.

    Someone below used "hysteresis", but I'm not sure if that's the right word. Basically, I noticed a regular intense flickering. It's very fast, to the point of being nearly unnoticeable unless I'm looking for it, but it's a real killer when it's happening.

    So you are saying that you don't notice the 120 Hz from the f.t. by itself, nor the refresh rate of your CRT, but you do when both are switched on?

    That is correct, although fluorescents annoy me slightly even without a CRT around to accentuate the problem.

    consider a front load washing machine.

    Dang! I can't believe I forgot to mention that earlier. I have a Kenmore HE3 washer/dryer set and they rock like no appliances I've ever bought. First, it barely sips water - the advertising is completely accurate. Second, the spin cycle is awesome. The radial velocity of the edge of the barrel on the "high" setting is something like 170 miles per hour. Third, my wife, three small children, and I use almost exactly one 5-gallon tub of soap every six months. At $10 per tub (we buy them once a year when you can get them 2/$20), that's about $1.70 per month in consumables. Fourth, they're huge. A big washer means fewer loads of laundry, which means that you don't have to spend a whole weekend washing your stuff. Finally, this giant graphite washer and dryer pair looks like it came straight out of Darth Vader's laundry room. It frightens small children and impresses the heck out of other geeks.

    They're still really expensive, but if you can at all afford them, you have to get these.

    Secondly, don't just use DPMS. If it's not a server, turn off the computer.

    There are sound arguments on either side of that one (largely regarding component life, thermal issues, etc.). On a newer computer with on-demand CPU throttling, I don't see a clear advantage to shutting them down completely.

    At any rate, all of my computers are either servers or iMacs, so leaving them on isn't that big of a deal. FWIW, I used to have a FreeBSD server sitting next to my Debian desktop at home. Since I didn't really use the desktop much anymore (I have Internet access at work, and wife/kids preclude me from having all-night hacking sessions at home), I recently combined the two into a FreeBSD server with a KDE desktop and decommissioned the dedicated-desktop machine altogether. That's one less system eating electricity, and I still have a comfortable system for the small amount of computing I do at home these days.

    Is it so inconceivable that some people want to save energy regardless of how much it costs to do so?

    Sure. Did it occur to you that some people go about it in really stupid ways that cause more problems than they solve? For example, you just trashed the environment to get your photovoltaics so that you could feel good about self-powering your computer. Your pollution-per-watt is much, much higher than the equivalent coming out of your wall.

    I want to live on a nice planet, too, but realistically speaking that means centralizing production to a few good, clean resources (read: nuke) than building hundreds of millions of dirty plants across the country. Short-term "solutions" that make us feel proud of ourselves without actually helping the overall situation are wasteful and not something to aspire to.

    If you're trying to live off the grid to see if you can or as a personal challenge: good for you, and I wish you the best of luck! If you're trying to do it because you think it's making the world a cleaner place, then you've wasted your time, money, and our natural resources.

    OK, I'm with you there. Basically, I'm one of those greedy, selfish jerks who refuses to compromise his lifestyle. However, I was also raised with "waste not, want not" and I hate the gratuitous use of resources. If I'm only buying one or two things at a store, I tell the cashier that I don't want a bag. I turn the lights off when I leave a room. I use DPMS on my monitors so that they're not painting a picture while I'm asleep. I keep my tires properly inflated. I have an electronic thermostat that's set to 68F during the day (in winter) and cooler at night.
