Happy birthday Slashdot! It's been a wild ride and I'd like to think the pace of change will decrease, but I doubt it. Strap in for the next 20! See you in 2037!
"The traders count milliseconds", that's three orders of magnitude out. Single-digit microseconds are considered significant in low-latency algo trading.
A useful ballpark figure is one microsecond is roughly 300 metres at lightspeed in vacuum (practically no different to the speed in air) but signal propagation in copper and glass is roughly two thirds of that - about 200 metres.
I commute by train and have a fairly low tolerance threshold for other people's inane chatter and noise pollution from crappy headphones. In a bid to stay out of prison for assault I invested in a pair of Etymotic earphones. IMHO they're arguably the best you can buy when it comes to sound isolation (as opposed to noise cancellation) and sound reproduction. They come with lots of different tips - you can even have custom tips made which are moulded to your ear canals. Expensive, yes. But they really work.
Without any music they're like a good pair of earplugs, which as you say still lets through the occasional raised voice. Listen to some quiet, neutral music, though (as mentioned by others, try white noise, nature sounds or gentle ambient stuff) and they really do feel like an isolation tank for your head.
You have my sincere sympathy - I too have suffered the chronic stress of other people's noise. If you can get the cash together, try these things out. They have greatly improved my quality of life.
Good luck.

You know what, I'm ranting, I'm off topic, and I apologize. My personal ethics (and lack thereof) are irrelevant to the topic. This isn't about our differences of opinion on whether piracy is right.
Posts such as this give me just a tiny bit of hope that Humanity isn't headed for the dumpster.
If you're looking for a performance hike by binding a thread to a CPU using taskset or ThreadAffinity, you'll want to steer well clear of any kind of VM.
In fact, if you're seeking any performance benefit by controlling what happens on the metal, VM is going to make that impossible.
Why don't you try running the cables inside metal cable conduits?
It's fairly expensive, but you can be confident no rodents will knaw through metal pipe to damage your cables.
If I remember correctly from my old physics undergraduate days, the total available power from the Sun is only about 1kW per square metre at the Earth's surface. That's across the entire spectrum. So even assuming 100% efficiency, it's still a useful thing to bear in mind when considering the viability of solar power.
If I remember correctly from my old physics undergraduate days, the total available solar power across the entire spectrum is only just over 1kW per square metre at the Earth's surface. It's a useful thing to bear in mind when considering the viability of solar power. even with 100% efficient solar panels, we're unlikely ever to run a house on a single small panel.
Well let's not get too serious about this, but I'd suggest that radians and degrees aren't really SI units like the Newton, because they're dimensionless.

Is quoting Wikipedia as a reference still valid these days?
Do you mean decimal? Because there aren't any units of revolution, neither metric nor imperial.
Although I suppose the imperial unit of revolution should really be the Lenin.

Maybe you've got a point. Next time someone suggests believing in their imaginary friend I'll try really hard not to laugh out loud.
I haven't investigated all green curtains, but once you've looked behind the first there is no need.
PAY NO ATTENTION TO THE MAN BEHIND THE GREEN CURTAIN.

I agree, and reading your post resulted in me signing up to EFF for $25 a month.

Reconsider your right to bear arms in the 21st Century.
I believe it's called a Hammer outside the engineering community.

Well said. If I had mod points, you'd get one.

Excellent response!
But would you use Trumpington's Rule Variations or the more accepted Tudor Court Rules?
