  1. Re:Delayed the release? on PCI Express 3.0 Delayed Till 2011 · · Score: 1

    AGP 1x and 2x were 3.3V, 4x was 1.5V and 8x was 0.8V.

    Afaict virtually all stuff that supported 0.8V supported 1.5V as well. So that left 1.5V/0.8V vs 3.3V as the main compatibility issue. There was a notching system that was supposed to indicate whether a card/motherboard supported just 3.3V, just 1.5V/0.8V or both and prevent incompatible combinations from mating. Unfortunately some manufacturers miskeyed thier products.

    BTW PCI also had two voltages though the lower voltage was generally only seen on pretty high end boards (all the higher speed variants of PCI needed the lower voltage).

    And there are lots of different ram types arround too though maybe not as many as there were back in the day, unregistered/registered/fully bufferd, different DDR versions etc. Then there are some machines that are very fussy about ram (this is apparently a big issue with the EEE 900)

    True but the main difference afaict is the length of the hydrocarbon chains and afaict thier main problem is chains coming out shorter than desired. So I imagine it would be too hard to adapt the process to make petrol.

  3. Re:I thought methane was a good substance...? on US Navy Tries To Turn Seawater Into Jet Fuel · · Score: 1

    1 - capture the Methane, and bottle it. This is called "natural gas", and is a great fuel, assuming you don't mind it being a Gas, not a liquid. I'm sure the Navy can figure out how to power fighter planes with this stuff directly, ... if they really have to.
    IIRC the trouble with methane is it's small/light molecules make it a PITA to liquify and store liquid (which are nessacery for high density storage).

    It can be done on a ship as evidenced by the LNG tankers that are now carrying methane arround the world (maybe they could use it to supply the carriers support ships) but I suspect it would be weight prohibitive for aircraft.

    2 - use Steam Reforming ( http://en.wikipedia.org/wiki/Steam_reforming ) to convert the methane to SynGas, then to Synfuel. Easy. Just ask Mobil. http://en.wikipedia.org/wiki/Synfuel
    But that would add yet more inefficiancy and complexity to the process.

    I would agree with you if it wasn't for the fact that 2.5.9, 2.6.0 and 2.6.1 were released on the same day.

    There are debianised source packages for 2.6.1 on getdeb (you have to follow the link for a particular distro release and then there is a source link there), dunno how well made they are.

    Infinitely more expensive than doing a simple free bank to bank payment online.
    Depends on where you live and where the recipiant lives. I looked into transferring money from my UK bank account to an ebay seller in germany that didn't take paypal (yes I know I should check before bidding and usually I do but when you are dealing with multiple auctions of the same product it's easy to get confused). It would have cost me more than the value of the transaction. Ended up sending cash through the post to settle the transaction .

    Yes paypals fees are annoying but for small international transactions what better alternatives are there?

    Also I worry about giving my bank details out, sure there are supposed to be safegaurds on direct debits but i'd still rather not have to deal with a fraudulant one if I can help it (you could get arround this to some extent though by using a savings account that doesn't allow direct debit)

    Afaict most plastics are made from small unsaturated hydrocarbons like ethene and propene which are then polymerised. Theese hydrocarbons are made by cracking bits off the less valuable hydrocarbons in crude oil (e.g. you take stuff that's a bit too heavy to be petrol, crack bits off and get petrol and ethene/propene).

    There have been some plastic-like substances made from biologically derived materials and i'm pretty sure other sources for unsaturated short chain hydrocarbons could be found too (they'd probablly just be a lot more expensive than cracking crude)

    ets say the gaming takes 10kB/s and the cmts is still 1000kB/s. If 100 users max out their lines at once then each user gets 10kB/s and your ping if fine. However, if there was 150 users maxing out their line at once you'd have between 6-7kB/s and since the game is 10kB/s your ping would jump up.
    Thats not generally how packet switched networks work, typically the switches and routers don't care what user a packet came from just when it arrived and which link it is to be sent out on. It is possible to make them care about the source but this adds a LOT of complexity.

    If a link is maxed out then the queue at the switch/router will fill up and latency for everyone using that link will increase by the length of said queue. This will happen regardless of whether the maxing out is caused by a load of users or by a handful. You can reduce this by using shorter queues but that increases the chance of packets getting lost if there is a sudden spike of packets.

    It also means what bandwidth a user gets will depend on how agressive they are at taking it. This is one of the big issues with both bittorrent and download managers, both get a larger than fair slice of the bandwidth by using multiple TCP connections in paralell.

  22. Re:Because that's how utilities work. on Comcast Finally Files Suit Against FCC Over Traffic Shaping · · Score: 1

    From most utilities we first world citizens expect good service more than just "most of the time". The power companies don't make judgements that your computers are more or less important than my electric shower. Despite this loss of power due to overloading is extremely rare in most first world countries because the power company has a good idea of the demand at a given price point and invests in sufficiant infrastructure to cover that demand.

    The real problem is that the ISPs have advertised and sold unlimited internet at prices that don't come close to paying for someone to really use their link at maximum a significant proportion of the time.

    You will notice that roads have a similar problem for similar reasons. The roads at rush hour get congested or even gridlocked because rather than selling the limited space to those who can afford it they make it a free for all.

    If you are going to have traffic shaping it should be up to the customer which of thier traffic they want to pay high priority prices for and which of thier traffic they want to send on the slack capacity, not based on a value judgement of thier content by the local monopoly/duopoly communication providers.

    Most other people are taking Checks, Visa, and Debit Cards as primary sources of transactions, leaving Cash a fourth level barely used.
    Maybe this varies by location but here in the UK for small transactions (like say buying some food in a takeaway or conviniance store) cash is by far the dominant form of payment. Some such places will grudgingly take cheques or cards but they really would rather not due to the fees (and often they set minimum transaction ammounts for card use). It is also more time consuming to take cards than cash afaict.

    At the supermarket most people seem to use either cash or cards, not really sure which is more common. Some supermarkets have even started refusing to take cheques.

    Cheques only seem to be used for large transactions with small buisnesses (e.g. paying a plumber) and as a way for buisnesses to pay off thier invoices from each other.
