Consider buying a Cintiq. It's exactly what you are asking for, with superb software and stylus support, at sizes up to 27" diagonal. A bit expensive, but this is a niche market, and you get what you pay for.
Sorry about that mistake. I'm not a FreeBSD expert, I'm someone who is setting up a FreeBSD file server, after 10 years of using Linux. So I'm in the market for a book like this, and of course it is largely useless to me, because of course I'm using ZFS. I was confused by the PC-BSD installer, which *does* default to ZFS.
Now that ZFS is the default operating system for new installs of FreeBSD 10.x, it sounds like this book documents a lot of hard won technical insights that have been made obsolete by ZFS. Why would I configure RAID 10 for UFS when ZFS provides superior data protection? And so on. It's probably useful for people who have parachuted in and now must maintain a legacy FreeBSD system. It doesn't sound particularly useful for someone who is migrating from Linux to FreeBSD right now, since this is all about how people *used* to configure FreeBSD storage.
The fabathome.org 3D printer is open source, has been available for years, and can print a wide range of materials, including conductors. It's never really taken off, probably due to having lower resolution than the popular FDM printers that print with melted plastic. But if you want a home printer that can print objects with a range of materials, including conductors, check it out.
As I understand it, this is a replacement for running a fibre optic link between your house and your ISP. Instead, you mount an antenna on your roof, which engages in narrow beam, line of sight 60 GHz communication with your ISP. I think the benefits are that it is potentially cheaper than running a fibre optic cable to your house. The signal is attenuated by rain, and by atmospheric oxygen. I doubt the signal can travel very well through walls. And I don't think it is useful for mobile devices.
You won't get any useful information by reading a Slashdot summary of a Telegraph summary of a New Scientist summary of a paper by Krauss and Dent on arxiv.org. Why not read the original paper, and decide for yourself?
I agree that the use of the Apache licence is the biggest problem with Android.
If Android had just used the GPL (which prohibits forking), then this problem would have avoided. There are lots of examples to back this up. For example, if Emacs had used the GPL, instead of the Apache licence, the XEmacs fork would never have occurred. And if Gnome and KDE would both switch to using the GPL licence, then the projects would just magically merge into one, and we wouldn't have the duplication of effort and lack of standards that you currently see on the Linux desktop.
Planets may be common in binary systems, but what about planets that support life?
One of the reasons that Earth can support life is that the distance between the earth and the sun remains close to a constant for the duration of Earth's orbit around the sun, so the Earth receives a fairly constant amount of solar energy. This means, for example, that the temperature doesn't go down to -200 in the winter and up to +800 in the summer.
But in a binary system, I would imagine that orbits that provide a constant amount of solar energy in the Earth-normal range would be less likely to occur. (What would such an orbit look like when there are 2 suns?) Are there any astrophysicists out there that can comment on this?
Stallman is standing up for his ideals. Linus has no ideals whatsoever, he just want things to work, and doesn't give a rat ass about the so called ideals. That's right.
In other words, Stallman is a visionary. Linus is just a great engineer. It's true that Stallman is a visionary, but Linus is not a great engineer. The early versions of Linux, that contained a lot of Linus's code, were absolute crap. Sure, Linus can write code, but he can't engineer his way out of a wet paper bag. But he's a great manager, and Linux succeeded due to Linus's leadership abilities, not due to his engineering abilities.
Stallman, on the other hand, is a great engineer. Emacs and GCC are testiments to this fact. But Stallman is a lousy manager, based on what I've read of the history of the Emacs project.
I have written a truly remarkable program which this sig is too small to contain. Wouldn't this sig be more appropriate in a law forum rather than slashdot? I don't understand your reference to law forums. My sig is actually a math joke. It's a snow clone based on Fermat's famous marginal note: "I have discovered a truly remarkable proof which this margin is too small to contain." And I am a computer programmer, not a lawyer.

Originally,/usr was an abbreviation of "user", it was where you put home directories./usr/ken was Ken Thomson's home directory, and/usr/dmr was Dennis Richie's home directory. (These are the guys that invented Unix.)
Then people started making home directories named after software packages. After a while, these names became standardized, and it became necessary to put home directories in some other location than/usr.
Everything in the universe that exists, has mass. Einstein discovered this. The gravitational field of the sun has mass, and this mass exerts its own, secondary gravitational field. Although this secondary gravitational field is small, it is large enough to have a detectable effect on the orbit of Mercury. When this effect was experimentally verified, it was a huge win for the theory of relativity.
The mass of a photon can be computed by taking the photon's energy, E, plugging it into E = MC**2, and solving for M.
It is true that photons do not have a "rest mass", as they can never be at rest, as they always travel at the speed of light. If we replace the terms "mass" and "instrinsic mass" in your posting by "rest mass", then your posting becomes correct.
From my poking around Google trends I have noticed that there appears to be a general declining bias for most search terms that either has to do with the declining popularity of Google (i.e. less folks were using Google for the past two years) or with the declining amount of searches in general (which is highly unlikely)."
I ran my own tests, and I think that the "search volume" axis is relative to the total number of searches on each day, rather than an absolute number. Most of my tests didn't show a declining bias, although I saw that in a few cases. I think the "declining bias" you saw might be caused by an increase in the diversity of search terms. Old search terms never go away, but new search terms are constantly being created as new names and catch phrases enter popular culture.
the funny thing is, Windows has had a indexed plugin compatible search built in since NT4.0 (1997?) It's called the Windows Indexing Service
Another funny thing is, the Macintosh has had full text searching for just as long. It was called Sherlock, and it was heavily promoted by Apple back in the day.
The term "nanotechnology" is supposed to refer to the construction of machines so small, their component sizes are measured in nanometers. Similarly, "microtechnology" refers to tiny machines whose component sizes are measured in micrometers.
However, in the referenced article, the so-called "3D nanostructures" are described as: "These three-dimensional hollow objects can be manipulated by hand and trimmed with scissors". The photos show simple hollow objects that are all larger than a U.S. penny. The component sizes would be measured in millimeters. So they at best are millicups, not microcups.
Nanotechnology refers to the construction of machines a million times smaller than this. You can't manipulate a nano-machine component by hand and trim it with a pair of scissors.
This is another example of researchers misusing the prefix "nano-" to describe work that is not even remotely close to nano-technology. Why is this important? This article would never have made the Slashdot front page if the prefix "nano" had not been used.
...would give the big phone and cable companies the power to pick and choose what you will be able to see and do on the Internet.
This has already happened, in the U.S., Canada, and elsewhere. The local cable company blocks port 25 (both directions) and port 80 (inbound). Since I host my personal web page and my personal email address on my own server, I can't use their internet service. The only reason I have unrestricted residential internet access at all is a Canadian law that forces the phone company to allow competing ISPs to offer DSL internet on phone company lines. I subscribe to a smaller ISP that offers unrestricted internet access over DSL.
You don't need a filter on jacks that don't have a phone attached. Electrically, it doesn't make any sense.
But it does make a difference. At my old house, I accidently unplugged a filter from a jack with no phone on it. My DSL service became extremely slow and unreliable. I phoned tech support, they got me to verify that all unused jacks had a filter. I reattached the filter, and my service went back to normal.
Don't know if you ever maintained a PC with a SCSI bus, but the same thing happens with SCSI. You have to put a "terminator" on each unused SCSI port, or the bus stops working. The terminator apparently prevents signals from bouncing off the open port and reflecting back into the bus. I'm not an EE, but I figure it's probably the same principle at work with DSL filters.
It really depends on your house phone wiring. I like to live in old houses with crappy phone wiring. The "new" house has especially crappy amateur wiring: too many jacks, too much phone wiring, and there is at least one phone jack buried inside the wall because the phone was removed, so I can't attach a DSL filter to it without ripping out drywall, and there may be others I don't know about.
As a result, the DSL splitter was really a necessity. If you live in a brand new house with professionally installed, high quality wiring, and you don't have an excessive number of phone jacks, then a DSL splitter likely won't make a difference.

OpenBSD 10 hasn't been released yet, so it is premature to say that "BSD users are the loser here".
