    Ah, but it doesn't have the same capability of the vcr. With a VCR, I simply say 'record' and it'll record my tv show without fanfare. This box will not record certian shows.

    How will consumers react when they can't do something they are now able to do?

    All of the newest copy protection schemes seem to revolve around the concept that joe consumer will give up certain abilities for higher quality or more bells and whistles. The new SACD, for instance, or HDTV with its record flags. They learned a lesson from macrovision - you have to put the hardware in the player, so you have to own the rights to anything that can play it (like every VCR has some royalties to, IIRC, RCA, but they require every manufacturer to put in a circuit which enables macrovision to work as a copy protection scheme). Thus, create a new format, create a new player (MiniDisc), own certian necessary patents (HDTV, MP3) and require everyone to buy into your copyright protection.

    Which, in reality, I don't have a problem with. If I miss a show, movie, etc, I haven't really lost anything - if anything I've gained time. But fair use is still worth fighting for, it impacts much more than just being able to watch a show when/where/how it's convenient to me.

    I was loving it right up to the point where they explain that these will be available through the cable companies and enhanced tv providers. This means that it will be rented by and owned by companies that control what shows can be recorded, and can prosecute anyone caught 'tampering' with the device in any way.

    If I could simply buy the hardware, great! But they know that they will make a more steady stream of money offering essentially a tivo like cable box to cable companies who can rent them to customers for $20/mo or more, who will gladly pay for them rather than $400 or more for a Tivo.

    It's a great business idea, and I see them putting Tivo out of business in the larger markets. Tivo (and other pvr companies) will have to maneuver furiously to maintain their current customer base, nevermind a growing base.

    But all is not so happy in geek land. You won't be able to record shows, or even pause shows, that providers don't want you to - and eventually that'll be most movies, lots of first run shows, etc. Skipping commercials may be disallowed at the providers descretion.

    It's essentially a bid to take back TV, while providing customers with a facade of extra functionality. I bet they'll win, since eventually service providers will be required to use such devices if they want to carry certian premium channels - though that's a while away, it's coming.

    After I was laid off (which wasn't that bad - one month's notice, no need to do work after notice. Could've been because I was expecting my second kid, and they were only laying people off to lower their costs so they could be bought out by another company) my supervisor attempted to perform some work on our old novell 4.1 server. The server stopped responding completely after a reboot, and they called me a day after when he finally decided he couldn't recover it.

    By then I was consulting for another company at $25/hr, so I simply said I'd charge them that rate. He agreed, I came at 8pm and finished rebuilding the server, restoring data and users about 4am. Sent them a $200 bill, and got the check shortly thereafter.

    He called a few times after for info about the isdn internet connection and other miscellaneous stuff, but didn't request that I come and fix things, and the calls were generally fairly short. Since they were nice in allowing me to later get on the router and download the configuration for another job later, I didn't think it was a big deal.

    The key is that they need to learn the connection between a smoothly working network and the cost of maintaining one.

    Parallel solutions on flexible cable will not be viable anywhere near the average front side bus speed, nevermind faster interfaces. Sorry.

    A not too recent slashdot article pointed out a unique way to manage large data transfers among clusters though:

    As a simple example, each computer has N 100Mb interfaces. There are a total of J computers. you use K hubs (or, ideally, switches), and connect them together such that one computer has direct hub access to a portion (or all) of the cluster. You can hook the hubs together using a managed switch or router if you want to enable them to contact all the computers in under two hops, without routing through other computers. This is very flexible - you could have it set up so each computer has more than one line going to other computers. Using managed switches you could even reconfigure it on the fly, though your latency goes up.

    The idea here is that each computer has a possible bandwidth of multiple times the network card speed. Furthermore, collisions are down, and latency is down. Throughput can reach higher than the practical 80% of ethernet bandwidth.

    The real problem with ethernet is latency and collisions. The reason it's used is because it's dirt cheap. Dirt Cheap. Commit that to memory. It's often better to buy a lot of slow devices than one expensive really fast device. You can overcome most of the limitations of the slow devices with other tricks.

  7. Actually, graphics hasn't come 'that far' on State of Speech Synthesis and Text-To-Speech? · · Score: 4, Insightful

    With all the amazing advances we have seen in real-time graphics, shouldn't speech synthesis have come much, much further than what is, seemingly, available today?

    We haven't had that many amazing advances in graphics. Natural speech is to advanced raytracing what current text to speech is to current graphics. We still cannot raytrace in a single system in real time at the resolution of our eyes, and we still cannot produce natural speech in a single system in real time at the resolution of our ears.

    Furthermore, we know less about the math of speech than we know about the math of light. Go visit your local university that has a good CS program, and browse the bookstore for the books used to teach speech recognition. In that book you will find that the average sound a human makes goes from production of complex, multitonal sound from the vocal cords through as many as five complex natural filters (body cavities between the vocal cords and lips) before it reaches the ears of the recipient.

    Modeling these filters for one sound is hard enough. Each letter in our alphabet, except simple vowels, changes the filters throughout the letter. Furthermore the filters for a given letter may also change depending on the previous and next letter.

    A system to create speech, therefore, must generate hundreds (perhaps thousands) of different filtered 'noises' just to reproduce the english language. Other languages can be much more complex.

    Current common technology is to simply record the hundreds of 'simple' sounds and add them together. Really good programs use hundreds of hours of speech by voice actors to get several hundred sounds.

    The penultimate is to mathematically recreate every part of the human vocal system from the lungs to the lips. This has obviously not occured. The computers may well be powerful enough, but the understanding of the vocal tract is extremely limited.

    In other words, wait 5-10 years. There still isn't a killer application for text to speech, but with devices getting smaller and smaller, there will be soon enough.

Monster.com has no links to my site, except to my full resume - and it's fun, though not particularily useful, to see that there are people going to my resume page from monster. It saves me the trouble of creating several different links so I can track where people come from.

YOU have control over that, though, since you can turn it off. Saying that it should be off by default without providing some real, tangible benefit is shortsighted.

Speed of serving is more important than annoying the few idiots who do refer directly to the images on my site.

    Lastly, it protects my image content. My images are not stellar, and yet other sites continue to use them on their pages. I can use the referrer to limit the damage done by only allowing the images to be referred by pages from my own site.

    Referrer information may be annoying to you, but it's an extrememly useful tool. If taken away one restricts opportunities for the site operator to personalize and protect content on their site. Not a huge loss, but it isn't really as great a privacy issue as you seem to believe.

  12. Glorified 2D barcode reader - could be simplified on Anoto-based Pens From Logitech · · Score: 3, Interesting

    This is essentially a glorified 2D barcode reader. The camera captures enough information in the little dots to know where it is with good precision in the 60 thousand killometer 2 dimensional barcode.

    They couldn't use an optical mouse mechanism because it can't tell where on the page it is. They have a 60 thousand kilometer space so if you go back to the same page you wrote on a week ago and make changes then it'll show up on the correct page.

    They could simplify it, though, by allowing generic pads to be made where each page in a pad is unique, but if you want to change to a different pad you have to scan the top bound ridge first so it knows you're on a different pad. The pads are currently expensive because each sheet has to be printed individually. Make it simpler with the suggestion above and you can at least make the pads duplicates of 90 different printed sheets.

    I suspect it'll flop. People will only buy the special pads for the pen, but they won't always have a special pad available when they want to write something down.

    I think a simpler technology could suffice here with the parts of an optical mouse. It only needs to know which words are continous, and you can reformat their actual layout later, if needed, on the computer. Add a cheap accelerometer and it'll have a good idea of where things are in relation to each other. Add some powerfull post-processing software and it'll be able to eat drawings as well, matching up areas where the camera saw previously drawn lines.
