    There has been research, lots of it, and conferences and RFCs and discussion and development and testing and everything else and it led to IPv6. You seem to suggest that someone is going to come up with a magic 'new' network protocol from out of their arse, which seems unlikely. Nobody wants IPv6 because for the most part IPv4 works for them. When that stops happening there will be a shift towards IPv6 (hopefully, I can imagine there will be some horrible bodged setups that sort of work, but not on tuesdays if it's raining before then). The other issue is that people are afraid of having to remember longer numbers.

  3. Re:Nothing new on Students Are Always Half Right In Pittsburgh · · Score: 1

    But wouldn't you be better off assigning a fraction of the years marks (10% - 30%) to tests taken during the term and the remainder on an end of term exam? Thus the students have some motivation to study for the tests, and rather than failure being a crushing blow it is a warning that they'd better get their act together for the end of term exams.

    Alternatively use coursework: applying the concepts that a course covers surely improves understanding and retention of those concepts? It also helps teach some time management skills, as well as providing a way for those who aren't as hot on exams to show their capabilities.

    With both methods progress can be monitored so that students who are struggling can be helped before they get a final damning grade.

    As you said, there are plenty of people who can do the work but don't think: When I started my degree there were plenty of people who were much better than I was at remembering all the pointless details that were required to pass uncreative exams. When the course actually started to require applied knowledge and understanding of principles a lot of these people started struggling. If people are copying then try and give each person a reasonably unique assignment at school we had things like: - Essays from a predetermined list based on course text for the year or a student could suggest their own. - Science experiments based on something studied during the year (effect of heat on enzyme reaction rates, that sort of thing)

    The great thing about this approach is that you can copy stuff, but you have to rewrite it and apply it uniquely to your particular assignment, which requires to some extent that you understand what you are writing. Every coursework in science is going to have some boilerplate text about doing a fair test, but detailing how you are are going to make your test a fair test ensures that you understand the principle behind it. Unless you have people who are actually doing the work for them it's pretty solid, their friends can help them out by helping them understand the problem rather than solving it for them.

    Which seems to be a more modern phenomena. I've seen some of the old patents from BBC Research they were written as clearly as possible and with all relevant detail. They were apparently told to do this so that if a case came to court it would be easy to explain the content to a jury, who are unlikely to be technically minded.

    Thank god we have lawyers these days who can translate all the obfuscation for us, and hence patents can be completely unreadable.

    There are a huge number of companies out there that are not floated on the stock markets, and are privately owned by one or more people. These people are usually the founders and head honchos of that organisation. It is for these people that honesty and integrity is paramount since they have a stronger attachment to the company, and they have some of their own personal reputation staked in it.

    In this case, much as it pains me, it has nothing to do with windows, and everything to do with you getting the wrong tool for the job. You have a double garage and two cars, but you can't drive them both.

    I on the other hand have friends I like to let use my spare car: Things like VHDL Simulators and FPGA synthesis tools, that will gladly consume a core and several gigs of memory for a few hours. On a single core machine you might as well go to sleep because the system will be next to unresponsive while it's processing that kind of load (well windows systems, in my experience linux and unix systems maintain an impressive level of responsiveness even when they are being hammered). The core2duo in my machine at the moment means I can carry on using my machine and do the heavy processing (or do two lots of heavy processing and go to sleep).

    For me it's more efficient and convenient than having two PCs, and not as expensive. Which seems like a good solution. At the end of the day it sounds like you don't have any application that will make use of your extra cores.

    I use Ubuntu at home and I'm afraid the same thing applies: Unless you have applications that are designed for parallel processing, or you actually want to do more than one thing at the same time, then you won't see the second core get used. VMware won't magically parallelise your code, so unless you are running two instances that are doing things at the same time you won't see both cores get used.

    That's just the way things are: there aren't too many applications that are easily parallelisable that haven't already been parallelised.

    My point was that the cameras do nothing to deter crime - in this specific case drug dealing which was the reason for the camera to be put up - but that they simply move it, whether that crime be drug dealing (the law says it's a crime, whether I agree with that or not is irrelevant in this context) or vandalism or any of the other things you mention. You won't get mugged on that footpath either, you will get mugged around the corner where the camera doesn't point.

    I concur. I got stung a couple of times as a student. Go past your overdraft limit and all your payments stop. Get charged for unauthorised overdraft , £35. Direct debit can't be paid £35. And just to ice the cake, the next time you put some money in your account they try and take the fees. Of course they don't check if you actually have enough to pay the fees so you go past your overdraft limit and get charged another fee. It's a real vicious cycle.

    I found that going to the bank and calling them a bunch of bastards worked and that there was no way I was paying the extra charges because _they_ decided to charge me when they knew full well the money wasn't there usually got most of them removed. Things like the direct debit charge though - it costs them _nothing_ to process that. They send a message back to the company expecting payment that the amount isn't available and that's it. The creditor (e.g. phone company) then sends you a letter saying they still need payment. How that costs £35 is beyond me.

    Also, I can't remember exactly off the top of my head, but there is some misleading stuff being bandied around by the banks re. this High Court case. It only applies to certain kinds of charges (I think being charged for going overdrawn when a free overdraft or larger limit would have been freely available) not many of the other charges that are unfair. Of course the banks are refusing to refund _all_ charges because of the case, even if they are not part of it.

    Exercise releases endorphins - opiates that are more powerful than morphine, which is what people get addicted to. My guess would be that you may become psychologically addicted to the buzz of exercising, but you can also become physically addicted to the endorphins that exercise releases. IANAD but I'd imagine the difference is that psychological addiction leads to a craving whereas physical addiction will have actual withdrawal symptoms.

    Heroin and other opiates are so effective because they operate on the same pathways as endorphins. They also start to replace them: your body produces less endorphins because of the heroin, hence why heroin withdrawal is painful.

    All encryption can be broken. The solution then, is to ensure that the encryption cannot be broken within a useful timeframe. I really don't care if you manage to decrypt my credit card number if the card has already expired. If I'm having a secret meeting this time tomorrow then the encryption only needs to last just over 24 hours, since by the time you work it out it will be too late.

    I actually think you've got it backwards. Encrypt them strongly and you can put the data on a billboard in the centre of picadilly circus and no one will be able to work it out in a useful timeframe. Ever seen Kryptos? http://en.wikipedia.org/wiki/Kryptos The data is public, there are many thousands of people attempting to break it, and yet the hardest section remains unresolved. The acceptable risk is related to the minimum amount of time that you can allow for the code to be broken, which determines how strong you need your encryption.

I'm not denying that it is possible, or that it is a terrible thing that causes suffering and misery, but it is not a 'real threat' to the western way of life, or any others unless we allow it to be.

    Contrast terrorism to any large war in the last few years: Here people were actually occupied, countries invaded, sovereignty taken. How does two buildings getting destroyed compare to nightly bombing raids, napalm, gas raids? Tanks rolling through cities and villages? That is a credible threat to your way of life.

    I call BS. Do an experiment: Drive at 70 MPH in fourth gear, and drive at 70 MPH in 5th gear. Fuel comsumption decreases. Now if you are having to rev the nuts off your little engine to get enough power out of it for motorway speeds then suddenly it gets all inefficient.

    Case in point: I had two Ford Fiestas, both the same age, almost identical except one had a 1.1 litre engine, and the other a 1.4. Pottering around town, the 1.1 was more efficient, but on the motorway, the 1.4 blew it away. That's because in the 1.1 slightest incline meant changing down a gear and revving the nuts off it to hold speed, whilst 1.4 had enough power to make a downshift unnecessary.

    That's not to say that the very largest engine is the most efficient, but there is a balance. I think I recall reading somewhere that the 2.2 Diesel Freelander (apparently one of the most popular cars here in the UK) is more economical at motorway speeds than a 1.5 Renault Clio. In city driving this is not the case, where the extra engine size and weight of the freelander are its undoing.

    I agree though, I can't see for the life of me why they don't use Diesel engines in hybrids (other than, as you said, the US regulations). You can get a BMW 320D that will do 60 UK MPG, and still have 150 bhp and plenty of torque etc. Put something like that into your hybrid and you would likely have something that's even more economical and maintains the same performance.
