Indeed very good, with the minor problem of not supporting the concept of "customer", and therefore not having a customer's history. But in practice it works very well.
The problem with BSD is that many products that are actually BSD-based don't directly acknowledge that.
Many web-caches, firewalls, embedded systems for machine tools, routers... are BSD based, instead of linux based for instance, since the BSD-license is much more corporate-friendly.
But the end result is that no one really notices how widely deployed BSD really is, since it remains hidden by the same persons that sell BSD products, therefore weakning the creative environment witch originated the system.
That's how you really see the advantages of a license like the GPL, forcing others to contribute to the environment in a positive way, instead of being merely predators, and generally getting more steam into the project, instead of simply grabbing others efforts.
The web page that you cite mostly gives tabular data. (In some ways, data from the Hipparcos project is preferable to that.)
Well... that "tabular data" was the one used to make those wonderfull images you mention, that is: after much pholoshop retouching. I would say those images are more a product of human imagination than of the telescope itself:-)
If you wan't the raw data to make scientific analysis you are definetly better using the original *.fits files.
If you resample the signal to an higher quality and you do it correctly, that is using sinc() and dirac() math functions, the resulting analog signal, after all that processing, should have exactly the same quality.
I doubt those cards use anything more than bicubic interpolation thought.
This is one feature that greatly increases
the amount of desktop space you have. It is
awesome to be able to have an eterm and an AIM
message both floating on top of Mozilla - and
still be able to scroll through the webpage you
are looking at and type commands in eterm and type
an IM. All by just pointing at the different
windows. They all stay where they are and none of
them take control of your screen
FYI this was the standart way of handling focus
before the Gnome/KDE/Enlightment/etc
M$-window-emulators came to take
over the X11 desktops.
Just try using TWM and see for yourself.
Also, TWM looks quite crappy these days, but you have menus, and all the windowing functions available on other window managers, except for virtual desktops.
So you are indeed regressing to get lost functionality.
a 320 vbr mp3 can sound great on
most setups, i have kef 2005 5.1s so
i can hear the difference easily
between 256 and 320 and any other step up,
if you have standard computer speakers it
doesnt matter all that much what the
bitrate is of the music as long as it is
above 128kbps
You are one of those "audiophiles" that think
96KHz/24bits is still worse than vinil right?:-)
Well, I can tell you that using hight quality
headphones (>$150) from various trades, I'm yet
to notice any defect in mp3 above 192kbps,
except in some weird Kitaro music that uses a lot of white-noise-like effects, witch are obviously very random and spectraly wide and therefore
difficult to encode.
Even Symphonic orchestras sound just fine at 192kbps, you can hear all the violins, etc...
That's why I generally use variable bit rate at
the highest quality (about 200kbps in
Lame -v -V0 -h), so that the encoder can
adapt itself to different musics. Simple piano music usually encodes just above 185kbps, symphonic >200kbps and those weird kitaro's >250kbps...

Definetly... emacs is way more powerfull, as well as vi, but nedit for quick, painless editing really rocks.
And is the only editor really modeless for Unix I know. I mean really modeless: open the Find window and you can still edit your text. You can open N windows at the same time, each for it's own function, and they all work at the same time, just like old X11 programs used to be, and contrary to most windows programs where opening special window deactivates the main window.
Once upon a time I really needed to print a.pdf that was not supposed to be printed, so I got Ghostscript, the relevant encription modules, and changed the postscript source (yes, the modules are made in postscript) to let me print the damn thing...
Easy, fast, nice...
It was my first and only experience in postscript programming.
This is not new stuff, and I don't really see any problem with it.
Let's state things in another way: such a computer is nothing more than a physical system which (entire) evolution is used and monitored to accomplish a certain task...
Generally heavy computation is used to predict outcomes, to analyse data, normally related to physical systems, and any system is physicall.
Now, consider this: if you can built a system to such a precision you don't need to simulate anyting, anymore. Just built the damn thing fullscale, and if it doesn't work restart from zero.
What I'm saying is that a small model of a plane, for example, is a physical computer, built to model the plane.
The best simulation of a system is the system itself, if you can built arbitrary systems with little effort. And the technology to built this kind of machines requires us also to be able to built almost arbitrary systems, so in the end it will be useless to make use of it to built computers, I think.
I'd rather see every insititution, especially any using public money have to publish all articles, for free, to everyone, on the net
That was exactly the idea behind my original post. I consider science, nature, acm, journalXXX and journalYYY important. But government-funded articles should be made available for free, or perhaps for a small fee representing handling costs only, or transmition costs.
I wonder why most "hard" science is still published only in pay-per-read magazines.
Shoudn't this kind of research, mostly funded by with government money, be published in free foruns?
I understand paper and ink costs money, and atm-links also cost, but this kind of public-funded research should be made freely available to the interested public, besides perhaps being published in "reference magazines".
I predict that serious commercial colonisation of space will take place mainly with Russian technology, as they seem to manage budgets better and have more incentive to make their program work with commercial interests.
Don't forget the europeans. Most comercial space flights right now are done using ariane rockets. And that dominance of the comercial markets seems not to go away.
CLNP is hard on the router's processors. Unless you want MPLS used all over the internet it's unfeasible to use CLNP on very fast networks. IPv6 was made to be fast. Most of it's pitfalls are a result of that effort. And I think it will be even more an advantage in the future to have a fast protocol than another very complete but slow.
I've been looking at some documents about this phenomenum, only to discover it has been analysed with incredible methodology, by real experts... and until now we have only seen speculations.
I believe NASA, or ESA, or someone like those guys should really send 2 or 3 probes out there specifically made so that their trajectory can be very precisely monitored, but also made in order to minimize other possible factors, like gas tanks leaking and that sort of stuff.
Probably something like an advanced GPS satelite, without any propulsion means, as passive as possible, should be used.
ESA has an interesting project, not directly related to this, but witch perhaps will help a lot in revealing more about gravity nature.
Instead of dumping our money in ISS, space agencies should endeavour in less expensive and more productive stuff... like this one.
We could also send a probe to Pluto, never visited before, before it's atmosfere gets too cold due to it's orbit getting the planet too far away from the sun. Now that all missions targeted there have been canceled this would be an extra objective for the mission, witch could make it more feasible and less expensive.
Obviously this is only me thinking... few persons seem to agree.
.EDU is not limited to american universities. In fact my university here in portugal has a.EDU (www.ist.edu) registered since a long time ago, as well as the more usual www.ist.utl.pt
Well... I used ssh2 to establish a VPN between my computer at home and the ISP where I work over an insecure network (the internet) so that I can access and configure systems and routers inside...
My public keys were put in my home computer using old-fashioned floppy disks, to avoid man in the middle attacks.
Do you sugest I should use telnet and plain X11 instead?!?
If the monolith existed it would already been discovered, since the moon was already scanned with high sensivity magnetometers, and that was how it got discovered in the movie.

FYI a battery indeed acts as a negative resistor, injecting current into the circuit.

The problem is that the energy for that must come from somewhere

I know some 15-year-olds-wannabees... most of them are script kiddies. They don't know much about technology. They make dumb programs...
When I was 15 I was also a wannabe, programing away in pascal and basic, sometimes in ASM, and thinking I really understood a lot about computers.
Of course 10 years latter, now working in the core network of an ISP, I realize how stupid I was, and how ignorant I was...

Have you ever seen a Lisp machine? They boot fast, especially considering the lousy CPU (r3000@25Mhz I think).
I't the only other serious "system language" I can think of...
Of course, nobody codes in Lisp except academics, but thats another enterily different matter.

Ridiculous... in fact the Cray-1 worked at about 70MHz back in 1977 using ECL logic.
:-)
The evolution has been done mostly in the consumer department (CMOS), not in the bleading edge technology (Bi, ECL and GaAs).
You could have 50GHz CPUs right now if the demand existed. But it does not. Supercomputers are not that "super" nowadays
But the speed will not improve in the future by means of raw clock speed: the improved architecture will make the difference.
In fact that is already happening a bit.
"Infinite density" is crap...
In fact, considering you may live in an hyperspheric universe (closed topology), if you wannna see a black hole from the inside just look around!
Black holes can be very sparse, if they are very big. In a sense, they are universes on their own...
If the monolith existed it would already been discovered, since the moon was already scanned with high sensivity magnetometers, and that was how it got discovered in the movie.

Sorry guys, no monolith found
The voyagers are now escaping the solar system.
They used chemical propulsion and gravity assisted flight.
Ionic propulsion enables us to go into the stars, we only need some nuclear reactors to feed those thrusters.
Photonic propulsion is more than enought to go into the deep cosmos... the problem being more relativistic than practical.
