Submission + - How to Ditch the Grid With a Woodstove and a $100 (motherboard.tv) 3

HansonMB writes: Given one of my more immediate life goals is to be living in a somewhat self-contained cabin somewhere far away from all of this — yet still have a way to keep my deer meat frozen and my laptop charged — the Volo Stirling engine is very relevant to my interests. Basically, it’s a lot like an internal combustion engine, except instead of the heat coming from inside the engine via exploding gasoline, the heat comes from outside the engine, like from a woodstove. It’s an old concept, dating back to 1812, that got shoved to the side with the advent of the grid and the internal combustion engine. Detroiter Tim Sefton and his Volo Designs are aiming to bring it back, with plans to have a consumer-ready Stirling engine capable of generating a household’s worth of electricity ready by spring 2012, for less than $100.

Comment I like unity (Score 1) 798

I am a power user. I use CL continuously. I have also been using KDE since last century. AND I LIKE unity. Its different, it works (in 11.10), my programs (graphics and text based) run equally well as in KDE (SuSE), and CL is a only click away for power users. Thanks Ubuntu; we have yet another Desktop choice in Linux.

Comment Re:How do I make money in a free software world? (Score 1) 107

Oh come on. RMS has said that since ages. Look, how do we make a road? The state pays civil engineers to design and manufacture it, and then it is free for all. Of course it needs maintenance, and again the state pays people to the job.
Thus, if we need structural analysis software, developers get paid to do it and maintain it by tax money, and everyone has it for free.
Things change. Noone has a god-given right to earn money, if they do something that people don't care. To see how ridiculous is the assertion of the gggg-grand father, I will para-phrase it, A LITTLE :
I need to feed my family. I write SNOBOL code for a living. How do I get paid for doing this in a world where all software is in C++/Java/Python?

I don't believe Google is doing this. You have to concentrate on the (hard) facts:
1. Google search is free and efficient. If MS and (in fact most of America) drives Google out of business, forget search engines for free. And forget good results; MS has already shown that it gives you the results which MS wants to give.
2. Google maps. The same.
3. Google earth. The money that you need to get satellite photos is insane. Yet Google gives it for free. It has helped me and my colleagues enormously.
4. Google translate. A very essential tool for me and almost everyone I know. For free.
5. Google mail.
6. Google Lunar prize. If this does not convince you, then nothing can.
7. VP8 codec, which Google bought and set it free.
And if they make a buck with advertisements, then good.

"Debian kFreeBSD is a toy OS, people really shouldn't misunderstand that.''
It is extremely important to have more than one free kernel. In other slashdot stories we all have seen the attack to Android, which is basically Linux. How long before MS Apple and other criminals (convicted monopolists) attack Linux to oblivion in USA. I just hope, that Europe might come to their senses, and continue to resist software patents.
I had hope about free Solaris, because I believed that Sun could protect the OS with their patent portfolio. But now Sun is Oracle.
So, Debian kFreeBSD and Debian kHurd, are invaluable projects. It must be made clear to those criminals that if they nuked Linux, everyone would switch to a replacement kernel (FreeBSD) without affecting the userland. And if they nuked FreeBSD too, then we could switch to Hurd, and the criminals would have to start all over again.

By the way, of course Debian kFreeBSD would be a toy OS. Didn't MS say so about Linux at the start? didn't old Unix vendors say exactly the same about Windows? And before that wasn't DOS only for playing around with toy computers?

In this case NASA is obsoleted by Arthur Clarke who envisioned telecommunication satellites earlier. And the space race to the moon was started by Russia. It was their idea. Yet who does not credit NASA with rockets, spaceships and all space staff?
To repeat what /.ers have stated many times. Ideas (and non-hardware patents) are cheap. Implementations are difficult.

Comment Great news (Score 2) 18

I develop a free CAD program in my spare time. It would be nice to add (accurate) handling of satellite images. I am virtually the only developer, yet ESA does not seem to mind; it says an "organization" may be an individual and need not be a legal entity in order to apply as a mentor. And I know at least one Ph.D. student on the subject who would welcome a donation.
Kudos to ESA.

You do not give a reason why Windoze is easier. I will give you one why Linux is easier. My 8 years old son, has installed SuSE 11.3 in 3 computers today. Complete with all the applications. And connected to the internet. And 2 of the computers are laptops. In half an hour (for each computer). So, please. At least in slashdot, people have a clue.
