    @gulllars if you understand how the TCP-IP protocol works, you'll probably realize that even with the 1Gbps link, you can hardly make use of that bandwidth because the connection on the other end and many nodes in between can hardly handle anything close to a fraction of that speed. Information transferred over the internet is slowed down due to several branching effects and congestions, unless of course you are directly connected to a node using an exclusive channel shared by nobody else.

    @neonsilkworm i live in a coastal town (13K population) in Norway, and the main fiberoptic lines from continental europe passes by just 4-5km from where i live, so 100Mbit with 3-5ms latency average is about $150 a month, cable TV and free IP telephony (to landlines) included. Note that half the line goes to 2x HD cable TV boxes, and the rest (50) to internet. An upgrade to 100Gbps full duplex internet + the rest would cost about $250 a month.
    The infrastructure to my house supports 1Gbps.

    @Chitownboy1023 Yes! Yellow laser light is used to project a Laser Guide Star in Adaptive Optics systems.
    From Wikipedia | Adaptive Optics; 'Sodium guide stars use laser light at 589 nm to excite sodium atoms in the mesosphere and thermosphere, which then appear to "glow".' ...and it looks cool, too. (I added that bit!)

    Is this an alternate FFreethinker channel? I just noticed the bug is similar.

  • @neonsilkworm

    @bokkpokk I was thinking the same thing. But you gotta remember, to appeal to the general masses who don't understand anything they're seeing, it looks really cool.

    @subh1 TCP-IP has it's limits, that's where the low latency and no bottleneck on my end or my ISP comes in handy. The bandwidth used rarely exceeds 20Mbit when browsing, but when loading sevreal youtube videos while syncing backup to FTP and maybe having a couple of torrents going, or all that while gaming, the connection is just epic. Since i have a 3,6GHz 6-core (which i can easily OC more if i want), 8GB RAM, and 4x C300 SSDs in RAID-0 i don't have any major bottlenecks in my system either.

    Probably an ignorant question, but how do the people in Europe now get near instant data if the cable itself doesn't connect straight to there?

    All these haters about the technical features of ESO... I've never seen such discontent over seeing HOW they capture the images and analyze them, and this video is just a scratch on the surface.

    @sergiomarchelli population growth is a problem because there is a limited ammount of resources that we can harvest from earth.. as long as our energy sources and consumption habits remain the same we will be coming to trouble.. unless i got you question wrong.

    @gulllars You must be handing some serious payout for that bandwidth...

  • @gulllars
    @gulllars 14 лет назад

    It's great you're going from an microwave wireless to a fiberoptics connection, but instead of using fuzzy metaphor sizes, why not just (or in addition) include the actual bandwidth in the standard Mbps/Gbps meteric?
    Also, since this is a video about the telescopes, and not how the techical side of data transfer is in detail, this video is mainly empty talk, and could be summarized in a minute.
    Just as a reference, i have a 100Mbps full duplex fiberoptic link to my house...

    @Digitalwoodsman Yes, there is. Every ecosystem has a limit to how much biomass it will support. You can have all the money in the world, but if the land you grow crops on no longer yields, you will die.
    And by population control, we're not talking about killing people off, simply educating them so that they have less kids so that there're less people in the future.

    @gunnerdan70 - Now why did i not think of that. See, this is why in science we have the peer review process.... We did great science today, you and I. Now to publish my/our paper, obviously, like a true scientist i am going to publish under my own name ignoring any of your contributions to the subject. I think i will name the paper "The effects of porn on the ESA Telescope".

    @sooooooooDark I am German and I can tell my classmates sound much worse. Actually, for me he sounds very much British but I can't tell for sure of course because English is not my first language. I think most of our teachers always try to sound as much British as they can (except for the one we had last year, he'd been to the USA for one year), some with more, some with less success ;-)

  • @TheSpankymonkey
    @TheSpankymonkey 14 лет назад

    I think the problem with their data transfer issues are down to a lack of programming knowledge of compression. For example they could cut a huge chunk of data out by simply taking all the black bits and just compressing it with the value "EMPTY SPACE". All the white bits "WHITE STUFF" and everything else just file as "MISC CRAP". 3 elements of data, which then leaves plenty of space available for ESA's primary objective.... Watching porn. :-)
