Is there anything, an effect or otherwise that you don't see being possibly to recreate digitally. If so then what and why does this effect pose particular problems.
David Bowie has just release a new album=Heathen and its amazing. It has the same thematic range as stardust, but comes from a more mature, more patient musician.
I would suggest buying these two together to see how a genious progresses from one decade to the next.

It might be that they didn't want to include all of the necessary control for flash programmin in their system. With flash (maybe its just the kind I work with) you cannot write to or read from a single address. You are restricted to sectors, and have to erase (make all 1s) a sector before writing to it again. This involved plenty of control, and if they gave the user's access to the flash they would have to make sure that certain sectors were protected and that they're internal apps didn't cross over any sector boundaries. Sure this is probably a good software engineering practice in general, but sometimes more trouble than its worth when you are simply conscerned with getting your product out as quickyl as possible.
Man I am ever behind on the acronyms used in computing these days. I read the headline from this stroy and had no idea what it could possibly be about.
Or simply a boot from CD distribution. The game has full access to everything, if only people can write a config utility to catch all the naunces of each persons system. No windows events running in the background...if you have 128 megs of ram, the game can use it all.
Games used to come with boot disks in the 286 days, it made sense now, but I suppose with multi-tasking and all it loses its appeal.

I stuck my computer inside a wheel. It rolled away or I would post a link to it. The best part was that as it rolled it used gyroscopes to generate its own electricity, the more CPU cycles it required the more it slowed down. So to perform really complex stuff I had to climb a big hill and let it go. Those were the days!
Mori said the research showed that only the nerve circuits of sight and motion moved when people played videogames, causing a drop in the process of thought.
Hunh? Where are they going? It seems to me that if playing video games keep my nerve circuits in place I should be playing more of them.
I ain't no exbert here, but I reckon this article be a few coyotes short of a full pack. Ain't there somethin more to this silicone than how fast dem darn electrodes move a through it? Sure light is important, but don't a man want some substance to his bobblin? Shakin a bag a feathers don't do me no good, no matter how fast I can shake em.
But as things are done in teh computer industry and competition and anti-competition, it's hard for a user to make second nature anything because the industry keeps changing things.
I agree with this completely. when TVs came out they worked just likd radios, there was a dial you turned to select a station and then you sat and were entertained. Of course TVs were just liek radios and we have so many other devices that work unlike anything else we have had before. What I am not sure about is whether this difference is a result of innovation or of simply trying to actively differentiate yourself to show how "new" the thing you have just designed is.
HyperTransport technology addresses this bottleneck by providing a point-topoint architecture that can support bandwidths of up to 51.2Gbps in each direction. Not all devices will require this much bandwidth, which is why HyperTransport technology operates at many different frequencies and widths. Currently, the specification supports a frequency of up to 800MHz (sampled twice per period) and a width of up to 32-bits in each direction. HyperTransport technology also implements fast switching mechanisms, so it provides low latency as well as high bandwidth. By providing up to 102.4Gbps aggregate bandwidth, HyperTransport technology enables I/O-intensive applications to use the throughput they demand.
32 bits in each direction hardly sound like a serial bus to me?
Yes and no. Serial cables do have the thickness advantage, but an equivalently shielded serial cable has to be 1/N where N is the number of bits as long as a parallel cable to achieve the same maximum data transfer rate. This is from a basic EM point of view, that the electrical length of a wire is doubles as the frequency doubles.
Any shielding you can perform on a serial cable can be performed on a parallel cable as well. Differential pairs, like the ones used in USB reduce the capacitance the signals see and maintain the waveform shapes, but this is because for data transfer rates of 12 Mb/s or whetever USB is now days, the wires need a bandwidth of 24 MHz. An equivalent Parallel implementation would require a wire bandwidth of 1.5 MHZ which is pretty easy to design for.
There are of course many advantage to serial communication that go beyond these electrical considerations. It is so much more practical and easy to modulate a serial system than a parallel one which is why all communication (cellular, ethernet..etc) uses a serial baseband. Otherwise we would need as many carriers as there were parallel bits. Which is not really inpractical, as the fastest way to increase your data transmission rate on a cellular system is to use N phones in parallel with different ESNs.
So the moral of the story is any serial system can be made faster with a parallel equivalent. Certain systems are naturally more easily and efficiently designed serially, especially those requiring communication over a shared medium.
Yes, all of this is true, but the delay skew will never be longer than the travel distance, which means that a two bit parallel bus of the same structure is always faster than an equivalent serial setup.
Serial Connections have to be very synchronized, to themselves The one byte tolerance on transfer is much higher and more difficult to achieve than the a equivalent one byte tolerance on a parallel bus.
If serial were faster, as you said, computers would all have 1 bit address busses with enormous shift registers.
I don't quite understand how is by nature faster in anyway than parallel. Fundamentally it is the other way around. 2x the parallel wired, 2x the data transfer rate, plus all the handshaking is much easier

Everyone is trying to target the youth demographic with pagers, cell phones and what not. I think this demographic is best served by using the gameboy as a staring platform
Man if he calls it the difference engine I'll be sick all over myself. That was the worst book ever. How can a man who wrote such dribble ever proport to have anything worthwhile to say afterwards.
I do blame this bruce guy for that book and not Willliam Gibson.
The beautiful thing about PCs compared to somethign like DVD players and VCRs is that market penetration will have little effect on curbing demand. Once you have purchased one computer you are very likely to purchase another in the next 5 years. Compare that to VCRs: I have the same one I had 9 years ago, in the same time I have purchased 3 or four PC systems (notebooks etc.)
My parents have spent the first 10 years fo this study without a computer, but when they bought one, they jumped on the band wagon and have upgraded and will do so again soon. There is no other product out there...Well i 'm sure there is and I will receive a bunch of commments abotu which product experience the same phenomen, but my point remains.
