  1. Re:I went to Manchester on Historic Linux File Archive Created · · Score: 1
    Manchester had a lot of history connected with computing and was responsible for a lot of new designs. Later they were responsible for an opem ARM core. Certainly their hardware efforts meant building a lot of expertise in low-level system design, i.e. for the writing of operating systems.

    The Cambridge Computer Lab was also on the Microsoft Hit List for similar reasons, but they were less hardware but more operating systems and networking (remember the Cambridge Ring was the forerunner of the token-ring).

    Whether or not either location was still relevant now is another matter, but their history gave them considerable clout in the since research councils which ran the funding and many of the senior academics 'moonlighted' on things like advising the government's procurement policy.

    From Microsofts viewpoint, this has been a very good investment.

    A DC coupled amp handles low frequencies very nicely. A lot of domestic amps are AC-coupled means effectively a low-cutoff frequency as the stages are capacitively coupled.

    The speaker is what interests me. You can get sub-20Hz responses but as you put it without a nice big resonant cavity, it won't go very far. I seem to remember reading that some cinemas were once equipped with low-frequency generators for special effects, but that meant one speaker per seat.

    RTFA, all you need is a 7 metre pipe.

    Seriously, they don't mention what frequencies were used (can someone extrapolate from the pipe length), but getting transducers to work so low isn't easy and you would need a DC coupled amp. Bass speakers theoretically go down to 20Hz but the performance falls off.

  8. The perils of centralised distribution.... on Film Distribution Comes To The Internet · · Score: 1
    I really love the idea of being able to spend about $5-6 on a film which I then own and can rewatch. I think the idea of being able to get the independents is even better, bypassing the vertically integerated distribution system that only chooses what they think are blockbusters.

    The problem is distribution. I don't know how big this film is, but a good quality movie rip can easily be between 700MB to 1.4GB of data in XViD format, more if in another form like SVCD. P2P works because of the cooperative downloads and uploads which gives several hundred sources for some films. I don't know the file sizes for the new system, but getting a large file out to a lot of people over a shorting period of time is painful (ask RedHat about ISOs, for example).

    If someone is downloading, they can also almost simultaneously upload, meaning that large files propagate in a few days amongst thousands of people relatively efficiently.

    What is interesting is that not everyone deletes the downloads so thez can act as a kind of 'memory', distributing storage cost across the P2P system. Between the systems connected to a P2P system, the collective capacity dwarfs anything that a single business can offer.

    Ok, we have established that centralised distribution of very large files doesn't really work. P2P for very large files does work (particularly the more capable ones that allow files to be segmented with one being made available for upload as soon as it is downloaded) and it is a suprising efficient way of distribution.

    The problem is how to make P2P movie distribution into a business proposition. Perhaps compensate P2P users who offer movies for upload as well as just downloading. The problem is that the 'anti-leach' mechanism on many P2P networks is broken.

    I love movies, especially some of the smaller independent stuff, however getting to see it at a local arthouse isn't easy as they frequently have very short programme runs.

    The last point is that I don't want any of this 'UK-only' or 'US-only' rubbish. I know this is also connected with the rights, which are still country based, but nowadays it is outmoded to limit Internet based distribution in this way.

  9. A Story for You on Power Grid Insecurities Examined · · Score: 1
    A friend of mine works on fligh simulators. The fligh simulators are based on specialised computers doing the motion and the graphics - but they have no file store as such. They rely on 4 XP-Pro Pcs to serve data files that are used by the real time computers.

    He was upgrading a simulator belonging to a well known German airline company and this meant pulling interface cards. As the XP systems came from the simulator company, they were not running corporate edition so they came up asking for a new keys in the middle of the night (all those hardware changes) whilst he was doing his maintenance.

    Of course the machine wasn't on the net. There wasn't even a telephone nearby (mobiles don't work there) and he had to go three floors down to find an accessible telephone to get the systems reauthorized. Additionally, many offices are locked overnight. He was not happy.

    These days it is very difficult to run machines without any network connection.

    NASA has a much better idea now how to build a reliable RLV
    No, NASA as an organisation has proved that it can not retain engineering knowhow. Individual engineers might, but the management will not listen. Maybe they will now, but the managers responsible for the culture within NASA are still there.

    Also, the main point of NASA is as a pork-barrel for the constituents of the members of the space comittee. They are therefore constrained to producing solutions which can be directly translated into jobs.

    Private industry is more focussed - this tends to mean that they will do the bare minimum but get it done on time and within a budget.

    We may not be able to dodge patents completely so how about just codifying what many EU countries already do and that is to allow patents relating to the physical implementation of an algoritm only.

    The engines lasted about 300 hours or so - and that was the newer versions. The RAF didn't have many major problems with the harrier, apart from the slow speed.

    The Royal Navy had more problems but that was mostly due to advserse conditions. The RN prefer cautiously designed stuff with losts of space in the envelope to allow for reduced performance. The harrier always operated a bit on the edge.

    I saw the prototype P1127 fly and have followed it on and off over the years including the string of accidents that the USMC had.

    I don't know if you checked the link that I supplied, but you have about ten seconds to take emergency action before you pass out (assuming immediate depressurisation). The bends take some time to kick in because the blood is not directly exposed to vacuum.

    Loss of pressure has happened in one famous incident at NASA in the eighties when a space suit failed in a test chamber. The chamber was rapidly repressurized and the tester showed no ill effects (i.e., no bends). The bends take some time to happen. When diving, it may take some tens of minutes for the effects to become severe. Small N2 bubbles in the blood are nasty but until they become larger i.e., by aggregation, they are not major. With immediate recompression, the N2 will quickly dissolve again.

    The Soyuz 11 incident was also disclosed when the Russians started cooperating with NASA. In this case, the crew seemed to have about 30 seconds (the cabin took a little time to depressurize).

    There is even an idea that has been floating around about having an unpressurised space suit - i.e., just the helmet would be pressurized. The rest of the suit would be elasticated, which would provide counter-pressure to the skin, to prevent swelling.

    There has been a loss of pressure accident once in the Russian Space program (Soyuz 11). A valve stuck open and the cabin air was lost and the cosmonauts died. It seems they took many seconds to die (about half a minute) and it was just plain hypoxia that killed them - no boiling blood or whatever, that happened later after several minutes.

    From what I remember, the transition was hard but not impossible, particularly after the automatic stabilizing system was installed. I have actually seen the sideways skid during a display but the roll problem seem to have been fixed by then. In reality, vertical takeoff isn't used because of the fuel issues and the transition problem doesn't exist with the ski-jump.

    Yes, there is an RCS, (like a spaccraft) with exhaust gas vented fore and aft as well as at the wing tips. This actually goes all the way back to the P1127 prototype. The same flight controls are used both in normal flight and for hover.

    The harrier was always high maintenance, and the VTOL would hardly ever be used in reality because they just drank fuel. However, with a ski-jump, VSTOL was easy.

    Um, no. The harrier only started to have problems when the USMC took it over and attempted air-frame limiting manouvers. Essentially the use of vectored thrust in flight to make very fast changes of direction (i.e., for missile avoidance) did give some problems. The RAF didn't seem to have the same problems (although they did have accidents).
