Comment: Why not cut even more? (Score 1) 564

by Linknoid (#42847063) Attached to: On the end of USPS 1st Class Saturday delivery:

I think it's a really smart move, and I don't see any issue with cutting normal deliveries to 3 days a week, say Monday/Wednesday/Friday. They could still deliver higher priority mail and packages on the other days, but honestly, does it really matter if you get a bill 1 day later? If it's time critical, I think most people are going to use e-mail anyway, and if it's something that actually needs physical delivery in a hurry, why not charge a bit more for priority delivery.

For the longest time I never really understood what people meant when they're talking about rights, they're a very abstract notion. But I recently read a book about the Bill of Rights, and discovered that the term "right" in this context is the opposite of wrong, i.e. "right and wrong". So if you say someone has a right to do something, you're saying that it's right for them to be allowed to take that action (instead of wrong). That doesn't mean that anyone is required to give you those rights, but by saying it's a right, you're saying that if someone takes it away, they're doing something wrong.

Ever look at the periodic table of elements in detail? Notice how hydrogen is not exactly one, helium is not exactly 4, nitrogen is not exactly 12, etc.? Well partly that's because of different isotopes (carbon 12, carbon 13, carbon 14, etc), but even if you had a pure isotope, it wouldn't come out exactly. That's because part of the mass of an atom is tied up in the binding energy in the nucleus, and the binding energy between the electrons and the nucleus.

If you take hydrogen and oxygen and react them together, it will give off heat, and the resulting water will have a mass reduced by the amount of heat given off. I think I've even read that most of the mass of protons and neutrons is tied up in the binding energy of the quarks, and that the quarks by themselves don't weight that much.

Like another reply said, the only reason you don't notice this effect is because a even a few hundred degrees temperature change is so minuscule compared to c^2.

Oyster shells are ground up and fed to chickens as a source of calcium. Chickens need a lot of calcium to keep laying eggs every day, and if they get deficient, they can lay the eggs with thin or even no shells.

Actually, I wouldn't be too surprised if they actually used them in human calcium supplements as well. (I have no idea if they do, but it would seem reasonable.)

Yes, the human ear can distinguish vertical position as well. Ever wonder why the outer ear (the pinna) is shaped so weird? It's so it will distort sound coming from different directions differently.

Here's an demonstration I saw at the Exploratorium in San Fransisco, but you can easily reproduce this at home.

Close your eyes, and have someone standing beside you jingle a ring of keys near your ear, above, below, and adjacent. It's easy to tell where the sound is coming from.

Now bend the top cartilage over, so the shape of the ear is distorted, and repeat the previous experiment. Now the easy task of detecting direction becomes almost impossible.

SpitefulBen (201793) writes "What lessons should architects of high-availability services take from events such as the March 2011 earthquake and tsunami in Japan and the Amazon Web Services outage of April 2011?

Michael Crandell writes in Forbes, "These events prove that neither public clouds nor private data centers constitute a magic bullet for all the needs of today's businesses. In the case of the Amazon cloud, it may in fact have been its remarkable record of operational excellence that led customers to assume that the inherent scalable, redundant and global nature of the cloud would protect them from having their systems go down. It'(TM)s the ability to fail over to alternative cloud resources pools quickly and seamlessly that is critical to maintaining continuous operations. Already, ZDNet Japan has reported on several new cloud deployments by private companies and government agencies as a direct result of the earthquake.""

In spite of the presence of 60 police officers protecting the field, activists succeeded pulling out the plants and sprayed insecticides over them, ruining the experiment. The goal of the experiment was to test potato plants which are genetically modified to be resistant to potato blight. It's a sad day for the freedom of scientific research."

I used to indent parameters across multiple lines like that, but they're just too much of a hassle to maintain like that. I think it's just as readable and less work if you put each parameter on its own line, just give it normal indention:

if (AThing)
{
--->MyFunction(
------->parameter1,
------->parameter2);
}

or normal indention + 1 indent:

if (AThing)
{
--->MyFunction(
----------->parameter1,
----------->parameter2);
}

Only through hard work and perseverance can one truly suffer.
