  1. Re:Believe it when you see it on Breakthrough Efficient, Paintable Solar Cells · · Score: 1

    This article is a prime example of the only goal beeing the headline. About the only number in the article is the proclaimed 30% efficiency. All the rest looks very much like there is not even a single prototype. I very much doubt there is much more than a (probably excellent) idea and some lab experiments behind the entire thing.

    For years we have every couple of months there a new revolutionary way to convert solar rays to electricity. Unfortunately none has managed to work in the real world except the good old silicon solar cells.

    My car, as are most cars of my friends and collegues, are used as utility as for as long it makes sense economically. This is true for 90% of the cars here. I drive 25k km annually which translates to 250k over 10 years. At the moment I must decide if it makes sense to replace the clutch for about $ 1k to push the vehicle another two years or if I get a newer car now.

    The only time of the day I can drive on the highway without another car i sight is maybe betwen 3 and 5 in the morning. At all other times it is cramped. Such technology makes no sense if you are the only one on the road, but if there are lots of vehicles it makes a lot of sense.

    While it might not take off as stellar as the inventors hope I don't agree with most your criticism.

    1. Ubiquitousness: While the very first driver has no benefit I will certainly be useful as soon as there are 5% of the cars equipped. The transmission will be for hundreds of feet ahead/behind.

    2. Cost: True, but not as bad as it looks. All high end cars already have electronics enough, that one more does not add a big amount. First adopters can be motivated with gadgets like a garage door which opens automatically as you get home.

    3. Average lifespan of a car is more like 10 years, it's not built for more and becomes too expensive to maintain as it get's old.

    4. This will not change liability at all. The same rules apply. If you bang into the car ahead and try to get away 'he was not equipped' you'll get 'go to pay attention as driver' as reply.

  5. Re:For those not reading the article... on Failed Win XP Upgrade Wipes Out UK Government Agency · · Score: 1

    The Windows Update Server is perfect for the SOHO environment where a large number of individuals care for their own PC and install directly from the server. The *server* makes sure that the wrong patch don't get to the PC.

    However, there is no such tool for a large IT organisation who wants to control what patches are installed where. This requires a distribution mechanism (there are plenty available on the market) and an tool to apply the patch. This is where Microsoft ought to provide a usable mechanism, designed to do pre- and co-requisite checking and to work unattended.

    The Windows OS doesn't even have a decent software inventory which allows to list the level of the individual components. Windows and its updates is still managed at an individual file level, there is no notion of package grouping related items together.

    Microsofts problem ist that they provide an operating system with no secure way to apply patches securely on a large scale.

    If you apply whatever patch on a usable os (AIX, Solaris, Linux) the package manager will attempt to apply and then back ou saying there is a prerequisite missing. The result of the human error would have been 70'000 error messages instead of 70'000 broken systems.

    All enterprise clusters I know of are in the 2 to 10 node range. The only reason there is a cluster is because of automated failover in the case of node or site failure. Performance and scalability is of no importance, they just buy a bigger box if necessary.

    Some of the sites have hundreds of machines, all clustered in small, manageable units. These are high-end IBM AIX boxes, high-end fiber storage with two sites 50km apart.

    I disagree somewhat and would say it this way:

    1. Did they really think they had something ?

      They thought there was hope to find something, but didn't look closely enough to see these were all blanks.

    2. Was it a hope for IBM et al to buy them out and save a failing Company ?

      I think so. Unfortunately for them IBM preferred to stand up and defend its honour, than hand over a wad of money to shut them up.

    All other languages looked at are scripting languages with great interactivity. Just press/type 'run' after the bug is fixed and you get your instant gratification in milliseconds. Compiled languages like Java need e compile cycle. Java is the worst due to the long startup time of the JVM. I have never seen, even on multimillon-$ hardware, a snappy Java app. Even 'Hello World' has visible responsetime !

    I prefer the Java language over perl, python, php, etc. The structure helps me to rapidly stitch a reliable program together. But I use the others more due to the snappy development cycle. I want milliseconds, not seconds !

    4. CIO, business or tech guy: They need both skills. Business savy to communicate with the rest of the company and tech expertise to keep the tech part on track. Most of the time the tech part suffers, they rely on salestalk and projects are in trouble.
    5. Projects fail: It depends on the way you measure. If on time and budget it the mark, then many fail. Probably because the scope was not defined enough and reality caught up to illusion only during implementation.

  19. Spoofing again ! on TCP Vulnerability Published · · Score: 1

    This vulnerability relies in part on the problem that it is easy to send an IP packet with a false source address (IP spoofing).

    What is the reason preventing IP carriers from implementing anti-spoofing filters ?

    In some environments this is certainly difficult, but most carriers know if a source address of a packet leaving their network is valid or not and could just drop spoofed packets.

    In practice there will certainly be difficulties, but I think such filtering is a necessary evil like anti-spam and anti-virus mechanisms.
