Uniform Vehicle Code in the US says: "a car driving below the "normal speed of traffic" should be driven in the right-hand lane." though laws vary by state. See attached link for more details on a state by state basis.

Sounds like a car entering or leaving the roadway qualifies as belonging in the right lane.

Let's say I'm driving I-87 in the middle of nowhere, New York. Speed limit is 65. 3 lanes of traffic. The right lane, according to a defensive driver, would be for entering and leaving the roadway, which typically happens at speeds below 65. The center lane is typically for cruising at 70-75 and leaves plenty of room for people who can't plan to merge well. It's in excess of the speed limit, but it's the prevailing speed. The far left lane is for those wishing to pass at 75+. Defensive driving teaches us to stay out of the way by not moving around a lot-- speed differentials cause accidents. A strict adherent to the "left lane is never for traveling, keep furthest to the right and allow all traffic to pass on your left" would end up switching lanes a whole lot. A 75 mph driver would cruise in the right lane, come up behind someone doing 65, switch lanes left and potentially be an obstacle to someone coming up behind him at 85, who instead of navigating a single lane change must now change 2 lanes (he is traveling in the right lane at 85 when he's not passing, right? he's not a hypocrite?). Big lateral movements are where mistakes are made and where the margin for error goes way down. I'm not a strict defensive driving adherent, I will move to the right lane if I'm getting passed by a bunch of traffic and don't feel safe from police if I increase my speed (generally 75mph is my upper end of my practice these days) and I have been known to pass on the right if the left two lanes are matching each others' speed.

I'll freely admit that I've been the guy driving more than 25 mph over the limit (110+ in a 50 on Vermont 22A is my worst/best more than 10 years ago, retrospectively stupid given the livestock and deer I have since seen on that road), I have a bit of a taste for speed. I like to think I even have the skill to do it better than most. But let's not start claiming that it's safe by any measure. Limiting lane changes increases safety.

Heaven forbid you have to turn off your cruise control and pay attention...

That much aggression... Is it safe to say you're a male under 25? It might be a good idea to take a defensive driving class. Many states have regulated the price and you can get a free lunch by some providers.

my defensive driving instructor

Full disclosure: I was taking defensive driving because I was radared at 99 in a 75. I was honestly doing a good bit over that before I was caught and was standing on the brake pedal as soon as I saw the sheriff.

Incorrect.

I'll believe my defensive driving instructor over some guy posting on Slashdot. Here's his rationale:

Assume a three lane road and light traffic. The right lane is for entering and leaving the roadway. The left lane is for passing. The middle lane is for travel. The middle lane is the safest lane for travel under most any circumstance (some local conditions, of course, may change the general rule). Animals like deer and moose entering the roadway may do so from either side, even if you really don't expect them coming from the center median on the left. You stay out of the way of the faster traffic and need not excessively lane change for the traffic entering and leaving the roadway.

I bet your company ends up with a noticeably higher electricity bill, more so than you'd recover in bitcoins. I ran Seti@Home for a month on a single gaming grade system and my electricity bill jumped a staggering amount. But, I'd love to hear if I was wrong.

Let's say you're turning your screen off, and the delta between your tower sitting in sleep mode vs working balls-to-the-wall is about 400 watts. I think that's a gross overestimate since the GPU is mostly idle, but it's a strawman.

0.4 kW x 20 hours per day (24 hours minus the 4 hours you actually game) x 30 days (per arbitrary billing month) = 240 KWh. At 10 cents per KWh, it sets you back 24 dollars to run SETI for a month. Maybe I shot high for the power delta, maybe you game for 8 hours per night, maybe your heat is helping heat only the room you sleep in so you can turn the thermostat down in the rest of your house (net saving you money) or maybe your air conditioner has to work a little harder to throw that heat outside (half that $24 may be an additional adder to your power bill from the additional air conditioning for a total of $36).

Maybe you enjoy the project and the $20-$40 per month is worthwhile or maybe it's enough of an education that you now sleep your system as fully as possible in the cooling season.

It ran on a full TTL +5V. So it sucked down power. Lots of power. I've disassembled first generation Pentium chips, removing the golden cover that protects the die beneath. The die is HUGE! Much bigger than any current production CPU.

It may have run on a TTL +5V, but it was BiCMOS. Weighing in at 300mm2, it's less than a Westmere Xeon's 500mm2 and I think that's a pretty fair comparison of potential customers.

No longer "News for Nerds" Now "Inaccurate insights for imbeciles".

Your userid doesn't look new, but you talk like you are. It's been a number of years since people came here for the insightful commentary of the "editors", and even then it was pretty sparse. We all know why we come here, and it's not the editor who suggests that a diesel limo is the ideological diametric opposite to a solar powered car.

Honestly, I think /. got burned when they tried to stretch into editorialism and ended up with Katz. That guy could rant, and generally about things nobody agreed with. I think a better choice entrant into that field would have made /. a far more interesting site today, and I still hope they get a good commentator/ editor.

You... don't really understand poverty much, do you? There are discount Internet connectivity programs (Comcast Internet Essentials) that can get you online for $10 if you are below certain income criteria. Even if you're having trouble paying your electric bill, you can get help with that too from most utility companies.

Precisely.

There is no "proper", or "best practice" place. Your two questions are entirely dependent on your use-case scenarios. If you want to block flash scripts on your kids browsers, do it host level at the OS. If you are dealing with a gigantic 2000 employee office campus, then you'd want to probably handle that centrally on a giant honking appliance/router designed for it where you can centrally manage policy.

But ... you can flip both scenarios blocking mechanisms I just mentioned and they'd still work. "Proper" can be entirely subjective based on what you're trying to accomplish and other factors involved

A full, true, Raspberry pi setup that could replace a computer (including a case + power supply + sd card, etc) will run you around $85. There's not $85 of scrap value in an old P4 unfortunately.

ExtremeTech did an article on this:
http://www.extremetech.com/computing/148482-the-true-cost-of-a-raspberry-pi-is-more-than-you-think

There's been many valid points made here about the long term costs of power consumption versus the short term upfront costs of new hardware investment. Unfortunately the issue with most non-profits is they don't have the upfront capital to invest in say 50 Raspberry Pi systems, but they can easily spread out the power consumption over the long term of 50 P4's (as inefficient as they are - agreed!) through operating expenses.

Pittance? I helped a local non-profit earn $3000 last year by salvaging their "junk" through my volunteer work.

They're doing it wrong then. There's money in scrap boards, memory, CPUs, and the metal itself. I can understand turning the things away however if there's not a support structure in place for them.

Your kind of thought process is exactly the problem. A P4 system is perfectly usable given the correct software configuration, and as timothy already stated they're working well enough running Lubuntu to be a basic word processing/information device. Just because it's not the newest technology doesn't mean it's trash. There are plenty of people out there who would be perfectly well served by a basic computer that can run a web browser to look up information, and type up emails on it.
