I agree, let everyone pay for it, unless you want to be declared the first geek-saint. I lived in an appartment I I convinced the owner to put UTP in every room. I put a hub in the basement and provided internet access to my 7 neighbours for 5 Euros per month. Since my cable ISP had no download limit, only a 80kb/sec bandwith limitation (I prefer that over a 500kb/sec with 10GB dowload/month), I had no worries. Only a few people overloaded the network but I wrote a script called ditchthebitch.sh to take care of that.
Anyway, UTP is preferred over WiFi because of security reasons (tapping ito a cable is quite harder). Also, I have wireless and watching a movie over an NFS mount is impossible, with UTP at 10mbps it is no problem. So I guess for gaming wireless would be too laggy, too.
The only problem I had was nobody wanted to play against me. I played Quake against my neighbour once and I won with 30/-1. So I advice you to let the others win the first time..
This hydrazine really fascinates me.. from what I know so far(and I could be wrong in some aspects, I admit), it's corrosive, toxic(?), a monopropellant and ignited by electric sparks. My questions: what is "hypergolic" and wat is the chemical formula of hydrazine? Any idea?
I've also done multiple projects with Rabbit. It is a cool product, but the software environment is crappy. There have been many discussions about it on their forum, my main problem with it has always been the lack of a linker and #include is replaced by #use.. In these "used" libraries, you have to define external symbols in specially crafted comments.. basically the system is hacked together imho. They created a new IDE by the time I stopped using it, so that invalidates some other remarks I had, the older one was simply unusable. Also the compiler only runs on windows, I asked if they could bring out a command-line version for linux but they said it used the win32 api (a compiler using the Win32 API???). Together with the fact that shortly before that they didn't even have a command-line version for windows, suggested to me that the compiler was woven into the GUI. Again and again, bad design decisions boiled up in their software. But still, together with their TCP/IP stack, you can develop network-enabled embedded devices much faster and cheaper than whatever I've seen, if you can cope with some frustration.
PS: If you plan to use the rabbit, here's a free advice: there is no such thing as a signed char in DynamycC. char == unsigned char. It cost me a couple of days to realize.
Just bought a few anodized thumb screws at my local PC dealer, to replace the philips ones. It makes live a lot easier when you have to open your case, I consider it money well spent (and yes, they are colored).
It would be very interesting to see where the most controversial topics are.. and quite doable too, just check where text is removed/added frequently would give you a subset that could be further checked manually..
Hence, the growth rate would not be exponential. You simply cannot mix 'exponential' and 'slow' together, that was my point. Exponential functions are hard to imagine; their speed is exponential, their acceleration is exponential, ALL their derivatives are exponential.. They are beyond sight in just a few steps.. that's why a while(true) { fork(); } program is so effective in bringing your system down, very soon the process creation limit is reached.
The spread, while exponential, would be slow due to a nanite's size.
Have you ever looked closely at an exponential function? Suppose their number doubles every step (that's exponential). A day before the whole earth is covered with them, only halve the earth would be covered. So, while at the beginning it might go slowly, once it catches up speed (that speed doubles also every step!), there's no stopping it. Note that I'm just attacking this statement, I'm not saying it would be probable to happen or something like that.. Also, bacterial blooming in the oceans is a comparable event..
Very slowly? Staying in orbit is just like falling, but you "move out of the way of" the body (comet in this case) you want to orbit so you move next. Repeat this thought-experiment for the new position and so on.
It should of course read.. so you move next to it. My humble appoligies.

I just finished reading this fine book of Arthur C. Clarke (yes, he wrote 2001), what you describe has a striking resemblence of Diaspar, a city cut of from the universe where people were conditioned to fear the outside.. Just asking the question if there was anything outside the city would make the inhabitants flee in terror..
Agreed, but refreshing DRAM can hardly be considered a wiz bang feature IMHO.. Is it really that hard? Especially when you compare it to the complexity of the CPU..
To be safe, the system reboots when a memory allocation request fails.
Erm, the OS itself does this? I'm not saying it's not true, it just sounds really unbelievable to me. Most of the time that's not what you want, so there must be a way to avoid it, no? Else, it's bounce-your-head-against-the-wall-time.. Anyway, I suppose this was the last field trip to mars for VXWorks? Maybe it's time to organize a Linux installfest at JPL?
Even if the memory handling is shitty, I wonder how it could have caused so much havoc.. How could it have caused spirit to go into the reset loop? It seems like some bad error handling code was also in play here (just guessing, the details aren't public to my knowledge..). Another thing that surprised me is that if the flash had been broken, all data had to be uploaded before the rover went to sleep.. every modern PC can continue to refresh it's DRAM while sleeping. Why can't spirit? Maybe a feature to consider on future missions?
1) Chanching the orbit to that of the ISS will take a LOT of fuel.
2) Even if you could work around the fuel-problem-thingy, it might be even more risky than a servicing mission; the hubble was not designed to perform a docking, so you would risk crashing it into the ISS. It wouldn't be pretty.
3) The thrusters of the ISS and leaks create a sort of gas bubble around the ISS. Not ideal for oservations.
4a) if you were to attach it to the ISS, the vibrations from the space station would make observations a problem.
4b) If it were to be floating around the ISS, you'd have a constant risk (see problem 2).
I agree, If I ever get to meta-moderate this, I'll classify it as unfair. However, even if it remains quite expensive to make for a couple more aeons, it could still be very usefull for experiments.
They cooled potassium gas to a billionth of a degree C above absolute zero or minus 459 degrees F
Uhum.. That's quite a bit colder than the temperature at the south pole of mars, where Nasa lost a lander because they mixed up some units.. We should have learned a lesson there: don't mix up units. hint.
So a better version could be something like this:
They cooled potassium gas to a billionth of a degree C above absolute zero or minus 273,15 degrees C
Agreed, I might be a bit pedantic about this for some, or I might just dislike the degrees F scale.. But it remains a good advice.
DNS is to the internet what the phone book is to the telephone system, with an added advantage that the dns system resides on computers, and computers ar just perfect for making queries. Imagine you'd have to buy a book and look up an ip addresses manually.. wouldn't that be great?
Doesn't this already exist for haircuts? I don't know a single hairdresser that has this, but then again I don't know much hairdressers, since my mother is one and we all know nobody can beat 'for free'. But I think she received an advertisement for it a few years back..

Don't forget to flush your buffers afterwards!

You have to take into account this joke takes place 30 years into the future..
It'll solve much of your "sterilization" issues as well!
Or it could create a mutated super-bug, take over the spacecraft and send it into a crash course with the new WTC towers..
I admit this is a somewhat worst-case scenario..
but no moron would set up a network in this way.
Try to keep an open mind when you talk about stupidity.

Auditing is boring.
Don't forget we live in a world where people collect stamps..

I've been playing with this before (to record nasa tv press conferences about the rovers), but I never got sound and video synced.. Any advice?
