Come on - the virus and worm anaology is a great one to make lots of... but they aren't evolving under Darwinian survival of then fitest.... if anything it's more of a creationist sort of thing with rival gods throwing their latest creations into the world to battle it out with nature (ie the rest of us who provide the medium for them to live in) and each other
next time you go into a computer store ask this question (and the time after, and the time after that)... want a computer from Samsung.... "I hear you have a MicroSoft approved 'trusted bios'.. does it run Linux? will it dual boot?".... if we don't ask it over and over again wont be on the Samsung(insert other vendor here) marketing dept check list for each new computer they release
The problem for them is that if the current stock price drops below $8.50 Baystar gets to bail on the PIPE deal and SCO is screwed (no way to pay the lawyers).... since the stock has been dropping all week (~20%), left floating around $9.50 they must be getting really nervous - this is a legal way for them to prop up the stock price and keep their nose above water
the satellite(s) send data to you on multiple transponders (frequencies), each frequency contains a bit stream that contains multiple programs (maybe 6-10 video channels). Every other frequency is on a different polariztion (so they can cram the frequencies closer together). Digital cable systems use different modulation techniques (noise issues are different on a closed cable, they can get away with more) but essentially the same idea, plus they mix analog and digital on the same wire (they call 'transponders' 'qams').
Add to that both US satellite systems use multiple satellites, and either multiple dishes or eliptical dishes with dual LNBs (heads) and a switch to switch between the LNBs/dishes (often contained within the dish itself). For example Dish runs a pair of satellites close together in orbit over the center of the country with the bulk of the premium content on it, households get a dual LNB dish to pick up both of these, they also use targetted spot-beam transponders to send local programming to particular areas (so they can reuse the same frequency several times) - less commonly used local channels (not the big network ones), HD and some foreign content is available on 2 satellites to the west and east (the west one covers Hawaii too) - if you want that content you have to buy a second dish and a switch. Cable has the advantage that all the QAMs run on the same cable, no switches are needed (except in certain older markets - Like bits of San Jose)
So a 'tuner' can only be tuned to one frequency on one dish at a time (or to look at it the other way one transponder on one satellite), certainly it can't blindly record any arbitrary 2 programs at any one time (maybe very occasionally by chance).
Having said that - having lived with a genuine 4 tuner DVR - it's great, we only run out occasionally (it's that sunday night simpsons/sopranos/etc time slot)

rtfa.... it's not 'welded shut' - it's a one piece from assembly that gets removed as a whole to provide even better access to the engine when you need to get there - having to add a 'door' in the front of the car puts some real engineering limitations on the shape and strength of stuff - and it costs money
They've provided access to the washer filler externally because they reason that that's the only reason people open the hood. I think they are full of it - do they really think that the quicky oil-change place down the street will want to be removing the whole front of cars even if it's fairly easy (and the associated liability - "you scratched my car" "no we didn't" "did too"....). I certainly need to get at the engine compartment on my truck fairly often (changing headlight bulbs, topping up oil, etc) - it might be a great idea for a new car and a real pain for an old one
I know about mprotect (of course we're really talking about MS software here). However part of my point was that you have to make things like mprotect REALLY lightweight - a cache and tlb (both data and icache) flush is probably the minimum amount of work required - that combined with a user->kernel->user context switch makes it hard to do really small JIT sorts of stuff. Processors designed to do this stuff (like Crusoe for example) have to have much lighterweight ways do this sort of thing
self modifying code is one thing... but there are real apps have needs to create code on the fly and execute it (great examples are Java JIT compilers, and wonderfull valgrind).... on the other hand a FAST, standard way to set the pages protections on some newly created code from RW- to R-X would be appropriate in these cases
not quite - read the stuff down thread about efficient radices of computation (e is kind of 'magic' and 3 is closer to it than 2). Having said that as I've mentioned elsewhere here current silicon(MOS) technology gets rather sad when it moves away from 2 states (it does move into analog domains and starts to bleed power)
'tertiary' logic and 'tristate' have different meanings. Tristate is simply a way of making a gate not drive a wire - so that some other gate can without 'bus fights' - there are no gates there that can sense that the wire is not being driven.
In fact the signal on such a wire will tend to hang around at about the level it was last driven for quite a while (the wire is a cap) untill it discharges or some other gate drives it.
In fact internal wires that are genuinely tristate are considered evil in most chip deigns - a floating signal will tend to turn on both the transistors in the gate(s) being driven causing current to flow where it shouldn't (one should be on or the other not both) - chips with internal floating nodes can et into horrible lockupstate which cause thermal runnaway and chip death. Normally if you are using tristate circuits you have a resistor to pull the wire to a known value when not in use, a weak 'keeper' transistor, a protocol which makes sure that someone is always driving them or a combination (PCI is a great example where all the bus clients know whow's driving each wire at any time and when wires are released they are first driven to a safe keeper voltage and then released so a weak resistor can hold them)
well by definition an 'invert' operation only has meaning if you have 2 values you want to switch between. The interesting stuff about trinary is in the information theory world where, from memory various obtuse math implies that it's a slightly better way to represent information (or is it that they are theoretically more energy efficient, I forget) - the big question though is "can you make groups of trinary gates that do usefull things in less area?"
Harder than you think - voltages on chips are + and ground (despite what people say here running a -ve power plane is probably not an option, it would add to area and result in all sorts of evil substrate problems) - any trinary gates have to be able to distinguish 3 different voltage 0 +V and something in the middle (more area there plus you're not running your transistors analog rather than cut off so you're wasting power) - really you need a whole new silicon technology with something other than fets.
I was hanging out with some people over xmas who were using these (or similar) cards - travelling up the California Central Valley they were able to stay connected all the way from San Diego ro SF.... untill the pcmcia card overheated.... cooled down it was ok - so bring the ice for those long road trips
Seems the stuff they are using basicly just uses spare ATM cells in the qams that are used for broadcasting cell phone data (they work a lot like a docsis modem) except that the basic response to signal strength getting lower is "yell louder and add more hamming codes"
I would guess that because the amount of spare downstream ATM cells available is highly dependant on how many slots are assigned to voice traffic - so about 5:15 downtown anywhere when everyone's just stepped out of work and are wandering around with their phones out would be a bad time to be trying to download the latest kernel source.... but at 4am the world's your oyster
it does in Oakland - at least in the new digital lineup - one of the things they seem to be doing as part of their fiber buildout is to expand their 'basic cable' lineup from 30 channels to include all of the analog channels (and I assume charge more for 'basic' in the process). I think they are probably moving analog channels to digital in the process.
Remember they can fit many digital channels in the cable spectrum that a single analog one fits - they need to move all the analog channels eventually to digital to provide more channels in the same space

Did US rules football get popular because it has all those breaks for ads so it got on TV more often and more people saw it? or did they change the game to add the the breaks for TV? I really want to know.
BTW (for those that don't live in the US) IMHO the main difference between US football and elsewhere is that you're allowed to go tackle people who don't have the ball
