  2. Options. on The State of Remote Desktops? · · Score: 3, Informative
    So to restate your goal you want to be able to use your computer remotely. There are several ways of doing this, each has their advantages and shortcomings; some work very well if you're on a LAN, others are better for slower connections. I'm sure their are more solutions then what I can think of here, but this is what comes to mind:

    VNC, WindowsXP Remote Desktop and PC Anywhere. These programs allow you to control your actual desktop remotely, as if you we're actually there in front of it. Unfortunately the way this works is by streaming image data over the wire, this can be very slow, like when browsing the web a good deal of the data is images. For something like editing text (e.g. Word-processing) some of the programs are smart enough to just send text data, so the response time is acceptable; even over slow connections.
    WindowsXP Remote Desktop is the best I've used so far, it seems to be very efficient and even allows you do 'share' your hard drives for easy copying of files, copy&paste of text works flawlessly and it also streams music that's playing on your machine.
    Unfortunately VNC's and the like do not work for games, streaming video or any graphically intense application. They only work well with a broadband or LAN connection, while they will work over a slower pipe, it can be quite a painful experience.

    Telnet, ssh: command line computing. Many people at slashdot will testify by it, and to be sure; once you mastered the tools they can be just as useful as their graphical counterparts. VI, gcc, and mutt can be just as productive as Word, Visual Studio and Outlook, it just takes some getting used to. However the tools can be limiting, you can't work with MSWord documents in VI, and you can't compile Win32 apps in gcc, so it depends greatly in the context of your work.
    The main advantage to command line apps are there very low bandwidth requirements and portability. Machines from the 80's can support a telnet connection over a 300baud modem, so you have no need for a modern windows machine to connect to home. For some, this is more important then being able to use GUI based apps.

    Web based, Client/Server. Back in the .com boom their we're some companies that we attempting to create full blown office productivity apps in HTML, and they worked pretty well. A Solid example is yahoo.com. They offer free (centralized) email w/ spell checking, notes, calendar and other stuff all from your web browser. Web apps are not as powerful as client side applications, but they are improving rapidly and will probably be better tomorrow, this is also where Microsoft and others are heading. Hailstorm (correct me if I'm wrong) is Microsoft's attempt to mix a client side application that connects to server side 'web services' to access your data. This may be exactly what your looking for, but it's not out yet.

    I work away from my computer all the time, I use yahoo.com's email because I don't trust other domains to stay around, and I need my email if my home computer isn't working. I use WindowsXP remote desktop for when I need to do something on my desktop, and I use ssh for when I want to mess around with my linux box at home or edit my sourceforge project page. They're all good solutions but are better suited for different tasks. I haven't used anything 'webservice' like yet (except messing around with .NET), but imagine I will within the next year or two.

    ...Windows Media, which was judged to be, by far, the worst format for quality. What does this tell us?

    I think it tells us that the reviewer(s) had some bias going. Other reviews i've read do not place WM8 squarly at the bottom, personally i think WM8 looks better then Real at lower bitrates, where Sorenson looks best at high bitrates.

    Either way thought there is very little seperating the three. They're all based of MPEG4, which in turn is based of sorenson. Real and MS have just tweak the formats slighltly, trying to get smother motion, a sharper image, and tweak the performance.

    Then there's companies like MediaExcel that have MPEG4 encoders that encode about 3X times faster then MS's, yet can't find a market.

    I've played with Darwin a bit, the thing to understand is there are a lot of peices to a 'media server'. There's a video encoder card (the oone they used was $2,000) and there's a encoder, like WMA, Real, or Sorenson. Once you put the video source and the encoder together you have a 'video source', which is what these media servers will 'serve' to the clients.

    You could think of Darwin as a amplifier, as it only does the TCP/IP server end, Real and Windows Media do the whole thing. It's also interesting that the auther credits Apple with having a such a wonderfull FREE product, but then lists the $250 Sorenson Media's Broadcaster and the $500 Sorenson 3 encoder ($499), not exactly free. While Real charges around 5k for the whole package and Microsoft charges nothing as it comes with Win2k.

  8. Mann is a jackass on Airport Security vs. Cyborg Steve Mann · · Score: 5, Insightful

    I just saw a 90 minute film on Steve Mann called Cyberman at SXSW in Austin, basically he has for about 20 years now hooked up a camera and video screen to his glasses. I believe his setup can now zoom, playback and bring up a crude command line prompt, he also has a single hand keyboard for input, and yes he walks around with this all the time. He also has renegade antennas setup around his city to stream video from his head to the web.

    However a few times they showed him going into retailers like walmart and gap with a consumer video camera (just to start shit). When an employee asks him to not bring the video camera in, he starts being a little smart ass about it. like "Well don't you have video cameras in here, why can you video tape me and I can't video tape you", "What if I told you that my glasses we're a video camera, would that be ok?". generally not agreeing with the store and making a jackass out of himself.

    I also saw him take off his glasses constantly, he would slip them off to do something, then put them back to walk around (then look around like a space cadet ), but it did not seem that he was in any way disoriented without his gear. So I don't buy that all of a sudden once his stuff was busted up by the security guards (which we're just trying to do there freakin job) that he started bumping into things, or at least not more then normally.

    I think what happened at the airport is that for "I'm cyberman" reasons he opted to keep his gear on, got shit from the security guards, proceeded to be a complete smartass while thinking, "if they fuck with me, I have it all on film", but when they broke his gear and is alibi that's when he really god pissed. I'm sure he was already expecting shit, but maybe hoping he could have covert footage of it to show the 8 o-clock news as well.

    The briefing a little to nebulas for me to grok, so i googled up this link on copyright extension, this one is regarding Disney.

    I think the main problem with IP law is that it is too cut and dry. For example I agree that Disney should be able to hold it's copyright to Mickey Mouse, but disagree that movies made by MGM 70 years ago are still not public domain.

    Mickey Mouse is a very important piece of Disneys brand, and Disney is a brand based company, so it's essential to their survival. Where movies from 70 years ago are simply rotting away, and will probably vanish.

    I think IP law needs to be based of need. A auction system would work better. Where after a relatively short period, say 20 years. the rights to the IP would become public domain, but are then up for auction. Disney would only have to be the highest bidder, which they could probably do, being that it's more important to them then to anyone else. The public needs to set a price however on buying it back, in case no-one else shows up to bid. I don't know how that would work exactly, but i imagine something based of it's past worth like 20% of the generated revenue from the IP. Of course calculating revenue from an IP isn't cut and dry either.

    While IP that companies don't care about are not worth the time or money to renew, and then become public domain. A good example would be old video games, the company that holds the IP have essentially forgotten about them. When the time is up, they either have to buy it back from the public, or give it away.

  22. Re:Freenet is not complicated on Why Freenet is Complicated (or not) · · Score: 2

    Freenet does not scale any better then gnutella. It has the same problem, which is flat decentraliztion. Meaning that every node has to pass trafic for every other node.

    Freenet only does this for hash query matchs, where Gnutella does it for search strings, so it might be slightly more efficiant. Freenets real problem is the way it keeps data anonymous. For data to get from point D to point A it needs to copy all the data from D->C->B->A which uses all the bandwidth of C->B. It also limits the download speed to the slowest of C and B. On the other hand it distributes the traffic, so while A is getting data slowly from D->C->B, it's also getting it from X->Y->Z and maybe N->O->P. Multiplexing the download would be faster for A, but looking at the whole picture a lot of traffic is passing through nodes.

    I think the biggest problem with FreeNET is that people compare it (unfairly) to Napster or Gnutella. I don't think it is trying to be these things, at least the design in it self doesn't speak that way. To me is seems like a robust system for keeping anonymous safe data, at the cost of speed and ease of use and resources.

    In the real world there is no active god, and if there is one he truly works in cryptic ways. With a virtual world this is a very definable god, the oraniztion that runs the world. Unless a virtual world can be run without people in the real world controling what happens it is very hard to even compare the two.

    Current virtual worlds are very static, the player can do very little to change the world. In EverQuest and DAoC a player can not start a even start a shop or build a hut. The only thing your avatar can do is kill monsters and sometimes other players. This should be exanded a bit when Shadowbane comes out (if it ever does).

    whats keeping it from working:

    The god of the world is also the ultimate dictator, if the people disagree with what is happening, the god can simply stop it. This elimates any freedom the players might have. The players can not topple the goverment, throw out the dictator and put a new goverment in place.

    The people can not defend themselfs from other nations. In this context "other nations" is the real world, and the border is the server farm. still is it a border (in a sence). but in the virtual world there is no means of self defence.

    Being as i don't like to be a complete pesimiest i'm forming a very vague idea on how it may actually work.

    Think of a completly decentralized network as the server farm, some type of p2p system. This elimates the problem of the server farm being raided. Think Everquest meets Gnutella. How would this work? I'm not to sure it it would. But the idea that came to mind was that the world could be zoned of into areas, where each area is a computer on the network. The size of the area is in relation to the power/connection speed of the host computer. Of course the problem with this is that that part of the world goes down with that computer, So maybe a redunt caching scheme like freenet uses would help out with that.

    People must be able to add code to the world. Perhapes making it open source would work. Where a group of people check a vworld 'plugin' (whathaveyou) for expliots and correctness and it is added to the 'hive'. So if a player thought it would be a nice idea to add a new longsord to the game he could make a 'weapon' plugin, submit it to the vworld group where it's checked by peers where it is then allowed to enter the world. Since there is no central server to proprogate the new plugins maybe some type of encrption scheme could be used to 'sign' a plugin. Of couse this adds some realworld dictator to the game, but it could at least it could be a democratic one.
