Come to think of it, that minidisc player probably used spdif internally already(optical input is anyway..). D/A's understand spdif too.. So just intercepting that signal and hooking it up to your sblive would do.. Might want to buffer it but it really should be strong enough to drive at least two receivers..
Find the D/A chip used in your minidisc(open it up first), find the docs for that chip online, locate the pin(s) that is(are) used for input (clk, ground, data), hook up a chip that can understand the data format(explained in the docs for the d/a used for minidisc) and convert it to spdif format and then hook the output for that to your sb-live..
Could most likely fit the whole thing on a solderless breadboard. Necessary IC's require really few extra components anyway. Hardest part would be to make the connections to the digital signal inside the minidisc(maybe solder some wires to the d/a-chip).
Not really detailed information but this is the general idea. As long as you hook up the chips correctly (follow the application notes on data-sheets) it's pretty much like playing with legos(digital electronics is that easy). If everything doesn't work right an oscilloscope is going to be helpfull..
umm.. it is actually good. Monterey was an effort to create a unified(sco, ibm,...) unix platform(like we need one more) that would run on most popular server platforms(IA-32, IA-64 and Power). Now that they have linux(that already runs on these platforms) this is not necessary and the resources devoted to creating something that users would have to pay big bucks for can be directed to something more useful(such as linux development). There would have been serious overlap with Project Monterey and linux anyway so why compete against a huge open source movement when you can join it.

That would be the boyz at MIT media labs.. They do come up with some funky stuff. I recall this thing being integrated into the sneakers and a microcurrent would flow during a handshake(or some other form of contact) exchanging information.
I wonder if they were in sneakers so that they could establish a common ground. I find it hard to establish a communications link(something like serial transmission) with only one conductor. Maybe it's a weak rf link that uses your body as an antenna and only being strong enough to transmit information upon contact..
Couldn't this port scanning be considered a malicious activity and if done by your isp(cable company) you could have a lawyer draft a nice letter for them where you threaten to sue them if they did not stop their hacking attempts.
Then again you probably wave this right by agreeing to the TOS, or do you?
Can't imagine it having more than a meg of rom. So that would still fit the whole operating system on two disks(with the gui). Probably something like system 6.0.7(before they named it macos) could fit (with the hypothetical rom image) onto a single 1.4meg disk.
I remember running MacOS 6.0.7 with less than 1 meg of ram used for system! In addition to this every time when you ran a program it would quit finder-explorer in windows talk-(you could choose between multitasking finder and a regular one) thus freeing quite a bit(relatively speaking) of memory for the program to use. Only one program could be active at the time. 6.07 would fit on a single 800k floppy I think (could have been a 1.44mb) with networking and printer drivers installed. With two floppy drives you could easily run a word processor. Eariler systems could fit on one disk(800k) with the programs..
7.0/1, was "multitasking" by default and i think that it used to want a minimum of 1.5-2megs. 2.5-3 megs had just about everything loaded. 7.5/8.0 wanted at least 3megs and with a not so minimal install it wanted over 4 megs.. This became a problem since my machine only had 8 megs(LC with 68020). I don't think I ever installed anything past 8.0 on this computer(maybe tried 8.5, not sure).
I think that my sisters computer(one of those early ppc-performas in a box.. imacs predecessor) has 8.5(maybe 8.0, not sure) with over 5meg footprint. One of the biggest consumers of memory is quicktime so if that is not necessary you can easily save several megabytes.. Earlier versions of quicktime are more memory friendly.. I couldn't comment on any later versions of macos since I stopped using them(pc's are cheaper, more upgradeable and run linux better and i don't mind figuring out small problems.)
Nope.. it was opening a connection to port 139 with oob-flag(a standard - unimplemented by microsoft - tcp-header flag) set. This would crash nt in a matter of milliseconds. It used to complain about tcp in bsod. Used to drive the sysadmin in my school nuts. Code for this was about 20 lines of C in linux.
Took our sysadmin a while(1-2months) to figure out the cause. And even if a fix was issued by microsoft fairly quickly there were many variants of this(opening port 139) which all needed a separate fix. And of course you'd actually have to install the fixes for them to be effective. I think you'd have to go to sp5 to have all the problems fixed..
I remember that if our schools computer lab was full we'd telnet to a server with oob-program installed and crash few computers at random(sysadmin only bothered to install the fixes on the server). After this happened few times those people would usually leave and we could claim the computers(this was a highschool so nothing too important going on).
It was Mitnick. Of course he is not getting the computer back (if you're involved in a computer related crime your equipment can be confiscated permanently) but the he still was asked to turn over the encryption keys so that they could decrypt the data..
When something is being broadcasted the traditional way it is literally pushed into our homes. All the content is coming in whether I specifically asked for it or not. In the case of cable or satellite I'd have to subscribe to the general service first but still the end result is that all of that information is being pushed to me. The good thing is that I can choose not to watch it if I don't like it.
Now consider streaming. It is more like renting a videotape. Nothing is pushed into your home unless you specifically ask for it. I don't think that it could be considered broadcasting in the traditional sense. Yup, a lot of people in a large area can watch that stuff simultaneously but it just isn't the same. If anything is being licensed it should be done the same way like with video rentals.
BTW. Is there anything good that's internet-related in Australia? With all the recent news it seems to me like the legislators down under are mostly out of their minds..
Uh.. Two words: Campaign contributions. Wonder why they're investigated all the time. Could it be that all those people weren't just giving money away for nothing..
I know this is not the point of your post, but still..
500,000,000 computers in US? According to Census the population of US is approximately 275,214,186 as of today. This means that everyone would have about two computers (can you imagine a two year old baby having two computers?). Yup, big corporations have lots of computers and their employees have computers at home but still at least over a third of US households don't have a computer.
According to the information on that Census-site in 97 (yup, things change) less than half of US population had used a computer! Now we'd probably get more like 70% have used a computer and maybe 40-50% own one.. Have to wait for the latest census information..
Actually on latest Amd processors there are no resistors but rather the multiplier is locked by burning jumpers with laser after the chip tested. Tom's Hardware has a little more on this..
In the case of AMD there is NO remarking risk. Upon startup the cpu is queried for it's preferred multiplier which is then set using some of the pins. Instead of using the response from the cpu these abit boards let you interfere with this process and set your own multiplier..
Bribery is a normal way of business in many places around the world. In US there are laws preventing bribery. In addition to this they are strong hypocritics about everybody getting the same opportunities(which is about never true in US, unless someone cries foul and sues everyone else).
Which is worse: French bribing(a normal business practice) or US spying one everyone. Personally I think that the French have a case regardless of bribery.
Knowing a thing or two about doing business in Russia I'd say that there is nothing unusual about bribery. If you want to get something accomplished you give money to the right person and things get done - unless someone got to him before you.. And don't pretend this doesn't happen in US too. Sure you can't give money directly but other benefits are most likely exchanged..
What was wrong then? I tried xf40 briefly with my v3500 and found that it worked just fine except for minor inconveniences.. I didn't want to break my debian upgrades so I restored my backed up xf336..
What didn't work was that plug-n-play monitor detection was after it loaded tdfx-driver. It went through modelines(virtual-there were none in the config-file) deleting the ones "out-of-spec" when specifications weren't yet known(resulting in horrible refresh-rates and resolutions).. Other thing that annoyed me was that gpm's repeater didn't work properly(there was a patch for gpm to fix this).. Or maybe xfree should just add a 3 button microsoft mouse to their driver(only supports 2 button microsoft mouses..) so i could get a rid of gpm..
Wake up from your dreamworld! Kids may be able to spend ALL of their income on whatever but AMOUNTS we're talking about are SMALL - especially when dealing with children that are 13 or younger(using probably sums of 1$ or so). And frankly, you can't expect anyone without a credit card to be able to consume much at all on internet, or in regular stores.
Earliest age I know of when teenagers start consuming notable(10$ or so) amounts is 15 and if we're dealing with purchases over 20$ it probably means that the kid has rich parents and doesn't really know about money that well(and what would you expect from a 13 year old?). Real consumption starts at the age of 17-18 when kids begin to be more independent.. Thats a long way from 13..
Seriously, would you listen to your 13 year old kid when choosing an ISP?..or your 13 year old kids friend? I wouldn't listen to anyone under 16..
First of all you can have a carrier frequency of 65856736.678 Hz if you so please. Second is not anything fundamental to nature!
Second of all... The real issue is bandwidth of transmission. When you're just transmitting this 65856736.678 frequency you're effectively transmitting with a zero bandwidth. Then again, you're not transmitting any information either. Once you start modulating this carrier frequency stuff begins to happen. You get sidebands and all that stuff. Some of these are required to reconstruct the signal in the receiving end(at least one sideband for FM-transmission, can suppress carrier and second sideband to conserve power). These sidebands are what use the bandwidth!
Whenever you modulate(FM) a carrier with a frequency you get sidebands for carrier + modulating frequency and carrier - modulating frequency. Only one of these is necessary as the other one can be reconstructed at receiving end and used for demodulation. Still, you're effectively transmitting with more than one frequency(thus using bandwidth).
There is a fundamental law of physics that defines the maximum information handling capacity for a bandwidth and it is as follows:
C = W x Log2[1 + (P/N)]
C is bits per second, W is bandwidth, P is power in watts of the signal through channel and N is the power in watts of the noise out of the channel.
This is the theoretical limit for transfer of information. Please note that this has nothing to do with dividing into parts of hertz but rather this is the fundamental limit. You give a bandwidth(that can include all those silly parts of hertz) amount of transmitting power and amount of noise and you get the limit.
The preceding law doesn't have anything to do with the modulation technique used. It just tells how much data you can fit into, say, the frequency area(also called bandwidth) between 65123456.7 and 65765432.1 Hz. This limit cannot be exceeded anymore than anything can travel faster than light in vacuum. In a real world situation you will end up with a transmission rate lower than given by this law.
And yes.. data compression can improve throughput..
CD quality sound is raw 44.1khz, 16 bits stereo. Why not just increase sample rate to say 60khz and have an even better estimation of the original analog sound. Only problem is that 48khz is about the maximum sample rate that any sound cards will output..
oh well.. Maybe should wait for dvd-audio that will do 96khz, 16 bit, quad channel.. or something ridiculous like this..
btw. to reproduct a sound with reasonable accuracy one needs to have about twice the sample rate as the highest frequency of audio. How many of us can actually hear 22khz or more? My hearing probably fades somewhere between 17-19khz.. Yes, we can argue about the effects of inaudible high frequency components but cd-quality is more than enough for me.
Yup.. And think about those over two(three?, four?) billion (China, India, Japan, etc..) people that probably don't even know what a bible is.. They'll all burn in hell with me..
I'd recommend you try new Boeing 777's on British Airways transatlantic flights. Personal videoscreens even on coach and a choice of 15 channels(10 of which are movies). Each channel has two movies during the flight. Business has few more channels and first class seats come with a personal movie library and your own controllable vcr(so you can rewind and fast forward). You also have your personal telephone - but no power outlets, I think. For those you have to go to business.

Mac 512k for sure didn't have, mac plus i'm not sure of, mac se(and all the models that followed) positively did have a 1.4meg floppy drive.
