    what could go wrong?

    Lots.

    worst case scenario?

    Depends how realistic we are being with our range of possible scenarios.

    Worst not-ridiculously-unlikely case: ill configured service, service minus important patches, or poorly chosen authentication/privilege setup, or something similar, allows an automated hack in and therefore the server becomes yet another bot in the net or possibly even a C&C box for the botnet.

    A zombied server is usually more trouble for the rest of the 'net then a zombied home machine because they generally have access to better bandwidth resources and are more likely to be openly connectible from the outside world so can more easily be used to host services such as phishing websites or a botnet C&C relay.

    There is also the potential loss/damage to the information in the server itself to consider. If a "noob" admin is running the server then it is not unlikely that the services and data held on the server are not adequately backed up.

  2. Re:Duh on Wear Leveling, RAID Can Wipe Out SSD Advantage · · Score: 1

    Yes, but the word inexpensive is being used in a relative sense here - the idea being that (ignoring RAID0 which doesn't actually match the definition at all due to not offering any redundancy) a full set of drives including a couple of spares would cost less than any single device that offered the same capacity and long-term reliability. And the expense isn't just talking about the cost of the physical drive - if you ask a manufacturer to guarantee a high level of reliability they will in turn ask a higher price for the device (both to cover R&D on making it more reliable and to cover insurance for in case it fails too early and you require replacement and/or compensation). Even if the individual devices in the array are very expensive, they are probably not so compared to a any single device that claims the same capacity and longevity properties.

  3. Re:Processor damage, really? on NVIDIA Driver Update Causing Video Cards To Overheat In Games · · Score: 1

    Wait a minute... just how is an overheating graphics card causing damage to a CPU?

    Depends on the airflow in your case, but many are not well laid out in terms of airflow. If the card is pumping out more heat than usual and this isn't being drawn out correctly, it may build up in the case generally, reducing the ability of the CPU's HS+F to cool it properly. Similarly, if the heat built up is sufficient for an appreciable amount of time (say, over the course of a long gaming session) you may also find drives and other components start failing due to overheating though the CPU is the item most at risk from this collateral warming and would most likely be the first to go (rescuing other parts by falling first, hopefully stopping the heat build up as no more head generating tasks will be run by it of give the the GPU by it) if the situation became extreme enough.

    Another GPU-killing-CPU-by-heat scenario exists in liquid cooled systems. If the GPU and CPU share coolant and the GPU heats up so much that it overwhelms the liquid cooling arrangement there may not be a sufficient temperature gradient between the coolant and the CPU for the CPU to be usefully cooled.

    I'd file both of these situations under "quite unlikely, but far from impossible".

Vista's key problem was lack of drivers for a lot of hardware and some of the drivers available for common parts were not all that stable initially even though they passed relevant certififcation. Second came performance especially on "vista capable" (or "vista ready", which ever was the lower designation) machines (many reported significant issues on better kit too, though this situation improved greatly with service pack 1). UAC was thrid on the average user's list of hates though it sounded worse as it was usually the straw that started the major rant "it asked me for confirmation X times before very slowly failing to work because of driver problems!".

    It depends on the size of the average commit. If most of them are small changes to single files then yes this is probably slow. But if a developer is working on a complex change then an individual commit could represent a significant number of man-hours developing, unit testing and regression testing before the commit. This is especially true if they are using some form of distributed source control whereby said developer has a local repository to keep inter-commit changes tracked in or if they are using a branch+merge arrangement (so the developer commits partial changes to a "personal" dev branch) and they are only counting commits/merges to the main branch/trunck in the above count.

This means you have to think that little bit harder about your day-to-day link clicking (assuming some of your contacts are like some of mine and their dribblings are not always easy to distinguish from spam/phishing).

    The real problem is more dangerous phishing - that which attempts to gain access to bank details or attempts to convince the user to let some local code to install. There is no way we'll ever completely stamp that out just as there is no partical way of completely stamping out burglary. The only thing we can do is to try educate the general public (spit) to be a little (or in many cases a lot) less naive. This is unfortunately much easier said than done - some people seem incapable of maintaining a healthy level of synacism when promised free smilies/cheats/porm or just "lols".

    Every now and then I consider starting a small spam/phish campaign that collects data, throws it all away, and give the user s "why the hell were you stupid enough to do that?!?!" message. Perhaps distrubuting it as an app that collects Facebook account details and uses them to post a message stating "is stupid enough to give their password to a third party website" before deleting them. The second most significan reason I don't do this (the first being I'm too lazy to bother) is that the idiots caught and made to look daft would see me as the enemy and not learn anything more generally useful (like "if one anonymous site promising free shit can't be trusted with my password/creditcard/wife then maybe others can't either") from the exercise. Maybe banks could do it with their own customer base though - send out a fake phish and lock the accounts of people that fall for it until such time as the phone up and promise to be more careful in future.

    But compatability is *not* a valid excuse for not installing something newer. It *is* a reason for not installing IE8 (you can't run IE8 and IE6 on the same machine without virtualisation of some completely unsupported hack), but it doesn't stop them putting on Firefox/Chrome/Opera/... alongside IE6 and just letting IE6 live for as long as the older apps live (which may be some time given my witnessing of a DOS based app in business-as-usual use two-ana-half years ago).

    They will not upgrade from "IE6 and only IE6" until the cost of doing so (design/testing/roll-out of new desktop builds, extra support time needed because if they go for the two browser stop-gap it will confuse many of their should-sacked-from-jobs-that-are-well-documented-to-require-computer-competence-for-not-being-able-understanding-such-things staff, paying for old software to be fixed/upgraded, and so on) is outweighed by the cost of staying where they are (those costs basically amounting to not being able to use certain software/sites (but they are big enough that saying "we'll consider your app if you support IE6" neatly sorts that) and looking like neanderthals (but the general public will never know and is doesn't really matter to them what us techies-in-the-know think)).
