  1. Beware long uptimes on Lessons From Your Toughest Software Bugs · · Score: 1

    I inherited a 'creaky' legacy system - and the server needed to be rebooted. It hadn't been rebooted in 5+ years.

    I did all of the sensible things: I checked that the backups were up to date - and then I manually copied the entire codebase and local data and database to another server before touching anything, just to be sure.

    Reboot ... dead.

    Restore everything ... still dead.

    After a lot of tracking down I discovered that a previous developer had placed critical config in /tmp /tmp was purged on reboot.

    I then discovered that the backup system was configured to ignore /tmp - because ... /tmp

    That took a lot of effort and guesswork to rebuild.

    Now I always copy /tmp before rebooting anything with a long uptime ;)

  3. Re:Simple vs Short. Round one: Fight! on The Science of Password Selection · · Score: 1

    The main issue with that type of method is that you don't know if the site you're connecting to stores the password in plain text or not - and there are a lot more out there than you might think.
    If it does, then you've just potentially revealed *every* password, for every account you own, on every site - because the pattern is so easy to spot and understand.
    As soon as that site gets cracked (which, if they're stupid enough to store plain text passwords, is going to be highly likely) - you're in deep trouble.
    Or maybe the owners of the site aren't averse to taking a peek into the password list and checking out the email account you signed up with ...
    Patterns are great for remembering - but you'd still need to have several, so that you can use different methods of generating passwords for different sets of sites. That way you can keep accounts partitioned and reduce the damage when one of your patterns gets outed.

  4. Re:I wish I saw this earlier on Feds Bust Cable Modem Hacker · · Score: 1

    I doubt making your own biodiesel and using it is the offence. The offence is not paying a tax you are legally required to pay. In the UK you can run your car on biodiesel if you like, but that doesn't let you avoid paying tax - you have to pay the tax directly rather than it implicitly being included in the fuel price.

    Actually, that's not 100% true. In the UK it's legal to produce up to 2500 litres of biodiesel tax free, for personal use. If you produce more than 2500 litres per annum you have to register for a licence and pay duty. http://www.lowcvp.org.uk/news/682/bulletin/

    "I worked on Skynet 3, 4, and 5, and I gotta call BS on you two." If you really had anything to do with UK MILSATCOM from the 80s onwards then I probably know you. Since different contractors were used on each of those projects, either you moved around a lot or you were my side of the fence - in which case I'd definitely know you. So ... are you calling BS on the fact that I worked on those programmes, or on the data throughput comments I made? Either way you need to back up that BS statement with something - or I call Troll.

  8. Re:Bandwidth on British Military Deploys Skynet · · Score: 5, Informative

    I also worked on Skynet 4 and 5. I'd have to disagree with the comment that the amount of information that is classified is 'ridiculous'. When you're talking about a system that all UK operations will be reliant on, you can't be too careful. In most cases, individual snippets of information might seem 'relatively harmless' in isolation, but combined with other 'relatively harmless' snippets of information can quickly reveal exploitable attack vectors on the system.

    As for the available bandwidth within the system - it's actually quite a complicated problem. That was one of the areas I studied. Knowing the power and frequency bands available is not enough to be able to determine a maximum data throughput on each channel.

    Different types of communications traffic use up frequency and power resources with different efficiencies. So the maximum data throughput varies - a lot - according to actual real world use. You also lose resources due to intermodulation products - which again vary widely with usage patterns.

    So when JacksonG says 'nowhere near as much as you might think' - it's probably less than that too ;)

    It's not just the search features. They *used* to have a 'sort by publication date' option on the display page (I generally just search for/buy books off them, so this was probably just for books) - so I could quickly check if any of my favourite authors had published anything new recently.
    I never used any of the other options (bestselling/price/alphabetical/customer review) as they didn't tell me anything I wanted to know. It's now disappeared and I have to scroll through the *entire* list. That one small change has annoyed me more than anything else they do.

    This seriously got mod'ed up?

    Come on, are there 'a lot' of terrorists out there searching desperately for US citizens to off? Randomly wandering around tourist areas - just in case? Really?

    Admittedly there's possibly a few thousand dotted around the world - but unless you actually go looking for trouble by visiting that quaint looking camp site in the Afghan mountains, your chances of ever meeting one are probably lower than your odds of winning the lottery.

    You're *much* more likely to get off'ed by any local criminals looking for tourists in general (on the grounds that they are easy pickings as they don't know the area and tend to carry more hi-tech items such as cameras etc). Being American won't make much difference to them.

    ... and what makes you think that an RFID on your passport is going to make you more noticeably American to the locals than say, your accent every time you open your mouth? Or what about the fact that your passport is *always* going to be readily identifiable as a US passport, RFID or not? If the problem is so bad, maybe Americans should be supplied with passports disguised as 'insert country of choice', and all given elocution lessons before they leave the US?
  15. Re:Full Paper on Dark Matter Exists · · Score: 1
    This experiment showed that the center of gravity of certain galaxies doesn't correspond to the center of the regular matter. In other words, the galaxy's gravity is pulling in a different direction than the normal matter would indicate. "[This] cannot be explained with an alteration of the gravitational force law, and thus proves that the majority of the matter in the system is unseen."
    That doesn't follow though, does it?
    Maybe I'm reading it wrong, but if the suggestion (that is being refuted) is that the gravititional force can vary in a localised area ... then these observations are still consistent with possible localised variations in gravity - they'd just need to take place on a smaller scale i.e. not galaxy wide.
    So, there's more 'gravity' over there (in that galaxy) than we'd expect to see ... this means more (hidden) mass or 'gravity' over there is different - just becomes there's more gravity over there (in those particular regions of that galaxy) ... this means more (hidden) mass or 'gravity' over there is different.

  21. Why bother? on Networked Landmines Work Together · · Score: 2, Insightful

    There is no effective way of 100% clearing an area of mines. The main use of mines is area denial. So, letting the enemy know WHERE mines are is not a bad idea. Either they then go around the field into the choke points that you want them in, or they spend time and effort clearing the area which either a) delays them or b) screams "here we are" or c) both.
    So why not just have every mine emit a clear radio signal? That way you (and the enemy) can have simple mine-field detectors ... it doesn't matter that they know where they are.
    Wire the transmitter into the arming circuit and build in a timer that defuses the mine after a certain period of time. That way, if the mine is transmitting it's signal, it's still live and once it's safe it stops transmitting. Then it's easy to spot if any failed to disarm, and you can use triangulation to pick out the few rogue mines that didn't disarm (or better still have the signal change on disarming, so that you can go back and clear up the duds too if you want to).
    ... but of course the enemy can triangulate too and that makes it easier to breach the mine-field, right? Except that you can seed the area with cheap emitters that mimic mines at the same time. The enemy don't know which are live mines and which are fakes - and you build in the same 'time to die' function into the fakes.
    Makes it easy to clean up afterwards and there's no need for self healing mobile mines as you can dump thousands of the fakes across the area to make sure that creating any gaps in the first place is *tough*. You might even find you can get away with using fewer mines in the first place.
