        > Just remember, security by obscurity is bad! ;)

        All security is by obscurity, that is a fundamental truth of any system whose state can be altered. You have to know how to get its state to change and if you know how then you can change its state.

        The issue is how much knowledge do you need to be able to change the state of a part of the system, and how much effort do you have to put in to get that information. Also how likely are you to be caught attempting to learn how, and how much of the system can you break into with that information before you have to learn more information (essentially the value of that information).

        Strong cryptographic authentication uses a mathematical formula to produce a *different* method of access for each key, and the key is a description of the method. Thus, cracking one key gives you access only to the systems that use the method that that key describes. For a weak cypher, it is relatively easy to determine the correct method to access a system.

        Similarly for *all* communication with a computer. If you know what software is used, and you know how to get it to respond, then you have access. So, since you are *always* relying on attackers not knowing the method to access your systems, you must ensure there is a different method for each system to limit damage when the method is no longer obscure.

        "Security Through Obscurity" refers to the technique where many system use the same method and depend on none of the other systems being cracked. This is risky: ie, chances of cracking are small, but cost of cracking is extremely expensive as all systems become vulnerable. Though chances are not so small as one may think as the value of the knowledge needed to access the systems is extremely high, and thus more effort tends to be dedicated to its discovery.

        This is why open source software will tend to become more secure over time (provided that there is a sufficient interest in its security - ie popularity). While it is less costly to discover the information necessary to crack a system, it is also less costly for the organisations that use it to discover that information, thus the systems tend to be fixed. That also devalues the knowledge from the perspective of the cracker. How many organisations will send their disks to MS for analysis vs how many can do the analysis with reference to the source code.

        All those little factors cause the initial risk of open source software to be much higher, but the risk of a mature and popular system to be lower. Compare with closed source, which for new and unpopular software the risk is low, and for mature and popular software, the risk is high.

        The best opportunity (as the world begins to realise the value of security) for closed source producers is to be cheap to market, quick to help mature an open source competitor, and quick to help your customers migrate to the open source alternative, siphoning a lucrative support and development contract as you move onto new product as restart the cycle.

    The BBC seems to understand the /. effect, so they've got a low-res, low-graphics, low-intensity page up to handle the load.

    The overview diagram points to a directory, so it can be virtually hosted anywhere, further distributing the load.

    Maybe they'd be kind enough to measure the /. effect and post a separate graph showing traffic with referrals from slashdot? Now that would be neato...

    ...it's possible to use tax funding to do some really intensely cool stuff. The BBC has a much better grasp of production (technical as well as aesthetic) in all forms of media than any of the pay services here in the U.S. Too bad we have the sadly underfunded NPR and PBS here. It could be so much better. NPR needs a lot more dramatic and comedy programming. PBS needs more popular entertainment that they haven't snagged from the BBC. But without the funding, we're stuck with the crap on HBO and Showtime. There is a definite lack of quality in US production. The same goes for HBO and Showtime's web presence. They have nothing on the BBC.

    Technically, this network is now owned and managed by Siemens Business Services. BBC Technology, which grew out of a few different parts of the BBC Engineers and IT depts, was sold to Siemens in October last year, to form part of Siemens Business Services, specifically the 'Media' part. SBS run the network both internally and out, as a managed service. This creates some interesting issues with network boundaries, and "who owns what", but it keeps us on our toes!

    Of couse, most of the same staff are there, so little has changed on that front. The lads and ladies in Maidenhead do a very good job of running a VERY complicated network. The BBC is the top content (not search) site in the UK, if not the world (don't quote me on that). The internal network is also pretty damn reliable, with a dual fibre ring running round most of the London buildings.
