    You don't get a magic increase in kinetic energy just by picking a different reference frame. A car going 60mph dissipates the same kinetic energy whether it hits a wall (where the push-back force is exerted by the anchors of the wall) or another car going 60mph in the opposite direction (the push-back force was inherent). Either way you get the same dissipation of kinetic energy whether your frame is standing still or moving.

    I'm talking about the news. Whenever a terrorist act is committed anywhere on the globe news immediately seeks to attribute it to "Al-Qaeda." The multitude of viewpoints and reasons for all the terrorists are lumped under a single umbrella.

    If it isn't possible to do this then the "mainstream" media will try very hard to avoid calling it "terrorism". e.g. the recent car bombings in Northern Ireland. Or how Mel Broughton is always described as an "Animal Rights Activist/Fanatic".

    All terrorism has been reduced to "Al-Qaeda" and since it is all that name there is no reason to think about the name.

    Or about who Al-Qaeda might actually be. Not well known is that first group of suspects arrested on the day of the 9/11 attacks were connected with an Asian government. Or that in 2002 an Al-Qaeda cell turned out to be working for the same government agency.

    but don't do anything beyond that because your predictions are guaranteed to be wrong and all those excessive measures actually make you LESS safe as they encourage people not to care and to skip steps.

    What CAN we do to reduce the risk ? Only this: effective after-the-fact law enforcement with open trials and proper punishment... same thing as for any other crime. Effectively catching the perpetrators, bringing them to justice (with fair trials) and then punishing them is a very good deterrent - just as much so for terrorism, and the only one that has any chance of working.

The first day was nearly a disaster, stalling repeatedly, lurching and shaking about, and requiring multiple attempts get moving from stops on hills. Simply driving was inefficient and slow (despite the car being a pretty nice old sports car), and required all of my attention. But I got used to it -- so much so that the next four cars I bought also had manual transmissions, and one was a newer, nicer version of that same car. Like the free and open source software mentioned here, manual transmissions take a bit of practice, but they are cheaper and can be at least as efficient (more mpg than older automatics, less maintenance), and being more in control is nice.

    In the case of older automatics you typically have 3 forward gear ratios as opposed to 4 or 5 in a similar manual car.
    In some places passing a driving test in an automatic means that you can only drive an automatic. Whereas someone who passes a test in a manual can drive either a manual or automatic.

    DEP is data execution prevention. It marks certain areas of address space as being "data only", so the processor won't execute them. While this is generally a good idea, as it prevents a hacker from constructing a NOP sled and then using an access violation bug somewhere to execute code they've stuck in memory, it also has the side effect of making self-modifying code more difficult to write.

    Given how hard self-modifying code can be to debug and formally verify making it hard to write is typically a very good thing.

    ASLR (address space layout randomization) is similar, as it breaks certain sorts of odd programming techniques like arithmetic variable addressing.

    While DEP does prevent stack overflow types of attacks, it also complicates writing high security software. The inability to execute data means:

    3. You can't place keys in executable code sections at runtime, making it much easier for someone to stop your program and dump the keys out of the memory image.
    DEP actually makes attacks against cryptographic software *easier* to implement.


    How often does regular cryptographic software need to do any of these? Points 1 and 2 involve self modifying code. Self modifying code is a good way to create a complete lack of any secuity. If order for software to actually be secure it needs to be verifiable that it operates according to the algorithm, this means avoiding both obfuscated and self modifying code. Even then small details matter, e.g. the Debian "bugfix" to SSL which reduced effective keyspace by orders of magnitude.
