  1. Re:This is prime PHB material, but... on PHBs Getting "Secret" IT Training · · Score: 1

    Depends what your definition of "many many tons" is.
    Mining trucks (eg. Caterpillar) have automatic transmissions that are the same in principle as your car's , except they weigh about a ton and have the same rough dimensions (maybe a little bigger) as a 44 gallon drum. Total loaded weight they move is normally about 300 tons at about 40MPH, from a 2000HP engine.

    Automatic transmissions are useful for their torque convertor which allows you to match engine rpm to transmission RPM under heavy load without damage.

  2. Telstra are "Bloody Amateurs" on Spam Slows Australian Net Traffic · · Score: 1
    As seen on whirlpool
    :

    I've just checked the mail server logs on several of our filter servers (we operate a service which filters spam and viruses out of our customers' email), and it definately looks like Telstra have sorted out at least their incoming email.

    We've got several thousand email customers who use BigPond, and our servers queues were clogging with huge amounts of email destined to extmail.bigpond.com -- mostly, our connection attempts were being refused. For most of the day yesterday (the 11th) and for at least a week prior, we couldn't get much of anything through; it wasn't until around midnight that we started to get email delivered.

    Even when we were getting good connections, for a while there it looks like Telstra's servers ran out of disk space. From around 6pm last night until around midnight, we were getting errors like: "Error writing message temporaries - message exceeds disk space available at this time", or "Mail system storage is full; try again later".

    Whoever manages Telstra's email infrastructure appears to be a rank amateur. Granted, they have a pretty large number of customers to serve, but with a scalable infrastructure there should be no problem. Other ISPs can do it -- Why can't Telstra??

    As for Telstra's explanations as to the cause of this whole mess, I don't buy the "artifically increased the load factors" line. From our logs at least, it looks like they simply broke their servers, and then when they did get them back up they were absolutely pummelled by the volume of traffic which was backed up awating inbound delivery. Bloody amateurs.

    In any case, from where I sit it does look like they've got their shit sorted out..

    If you go to a site or are veered to a site not listed in the "Trusted Zone", it will come up with a warning message and you have to explicitly add that site to the list.

    I bet that lasts about 5 sites, before the user figures out how to turn it off.

    Perhaps if they just bit the bullet and built a browser that was a bit more hardened, things would work out better.

    Double distilled (ie distilled from distilled) is fine. Well, conductivity from our still is about 18MOhm... that's *practically* nonconductive.

    For instance, 240V across 18MOhms is 0.01mA. For a comparison, a typical earth leakage breaker will trip at 30mA and stop you from being electrocuted.

    Problem is water is pretty much a universal solvent. Any stray coatings / impurities / dust on your motherboard will quickly make your water conductive again.

    On the contrary, with every drive manufacturer pushing their physical media to the limit , sector errors happen a *lot*.

    Disks die suddenly because they *suddenly* run out of redundant sectors to remap your data to. This remapping happens transparently to the OS, inside the drive electronics and can usually only be picked up by deteriorating S.M.A.R.T. characteristics. There's only so many redundant sectors and once they're all in use your drive goes downhill will every bump and jolt.

    Didn't you get all that stuff in school about how we were going to run out of gas/petrol/coal/etc in around 2002-2020. Strangely nobody has mentioned that in the last 5 years, that could well be because it was wrong or perhaps teachers were asked not to mention it for some reason.

    It's because reserves of coal/oil that were deemed uneconomic in the 70's can now be mined because of (a) improvements in technique and (b) people are willing to pay more for it.

    Rough estimates today put this shortage to be in the late 2000's - early 2100's. Of course, what we'll be doing then is anyone's guess.
