  1. Re:Summary not entirely accurate. on Valve In-Home Game Streaming Supports Windows, OS X & Linux · · Score: 1

    The common platform combinations for games on steam seem to be

    windows
    windows+mac
    windows+mac+linux

    I've never heard of a game on steam that didn't have a windows version. Apparently there is the occasional indie title that is windows+linux but not mac but they are a tiny minority. Once you put in the effort to do windows+linux doing mac as well is not a massive jump.

    So streaming mac to linux could be handy for platform compatibility in windows-free households. Streaming could also be useful to stream from a beefy PC to a less beefy one.

  2. Re:Where does 7 feet of water come from? on Rising Sea Level Could Put East Coast Nuclear Plants At Risk · · Score: 3, Informative

    Not sure why i'm replying to an anonymous retard but anyway.

    Water does have the strange property of expanding significantly when it freezes (and expanding slightly just before freezing). However above about 4 degrees centigrade it expands with temperature. Of the order of 0.04% per degree centigrade (depending on the current temperature)

    0.04% doesn't seem like much but the oceans are about 4km deep so a 1 degree centigrade rise in average ocean temperature would be of the order of a 1.6m rise in sea level.

    however the bigger concern is the release of water that is currently locked up in ice on land (ice on the water floats and so has a negigable impact on sea levels when it melts).

  3. Re:port it for pc on The Technical Difficulty In Porting a PS3 Game To the PS4 · · Score: 1

    Afaict console game series can be divided into two main categories.

    1: Those funded/published by a big publisher who is independent of the console vendors. EA, Take 2, Activision etc. These games may have a timed exclusive but if they sell well they will most likely end up on multiple platforms.
    2: Those funded/published by a console vendor, these are highly unlikely to end up on any platform not controlled by that console vendor.

    Afaict this one falls into the latter category.

    BTW, I note that the result was installing Windows 7. If it was doing that, does it mean they were running XP or Vista until just now

    Reimaging machines that already have win7 on them with a new win7 image is hardly an unusual thing to do. The intended target could have been an upgrade project or it could have just been a cleanup/update job keeping the same windows version.

    I suspect the machines that got accidentally reimaged were running a mixture of stuff before. Thats how things usually end up in a uni environment (at the uni I left recently I was aware of machines running NT4, 2K, XP, Vista, win7 and win8 as well as osx and multiple flavours of linux). At the time I left they were in the middle of a large scale effort to move from XP to win7 on staff/postgrad desktops (the public clusters had already been moved to win7).

    That makes sense in an environment where there will be someone arround who understands how to setup database servers, how to dump and restore the data from them and so-on.

    but if you are building something to "set and forget" in an environment where there will be no IT people arround after you leave and where the internet connection is likely to be spotty or nonexistent IMO a self contained single file that can be treated like a document is probablly simpler for them to deal with.

  9. Re:SubjectsInCommentsAreStupid on Ask Slashdot: Easy-To-Use Alternative To MS Access For a Charity's Database? · · Score: 1

    The problem with any client-server database is it's far more complex to deal with than something like access.

    With a simple access DB (I guess libreoffice base is similar but I haven't used it so I don't know for sure) everything lives in the mdb file. So you can basically treat your database like a document. Back it up by copying it to an external drive, restore it by copying it back, migrate to a new computer by copying it over along with all your other documents etc. It's all stuff someone of moderate computer competance can deal with

    With a client-server database setup backup and restore become far more complex, the data files, configuration of the datbase server and code/configuration of the client app (whether web based, access based, a standalone app or whatever) need to be backed up seperately from (and usually it's considered a bad idea to back up the database files just by copying them, so you have to know how the dump/restore tools for your db server work). If the restore environment isn't identical to the original you may have to reconfigure the client after restoring to get it talking to the server again.

    I can deal with this and the submitter sounds like he can deal with this but it seems like the OP belives that it's unlikely else at the charity will be able to deal with it. Furthermore from the way the submission is worded it sounds like he may only be working for the charity on a short term basis.

    Don't get me wrong, client-server soloutions have massive advantages in situations where you have multiple users hitting the same DB at the same time and where you have a sysadmin/DBA to look after the database but for single user "set it and forget it" setups they are the wrong tool for the job.

    The other big problem with traditional raid is it only saves you if the drive either dies or reports a sector as unreadable. If it just quietly returns the wrong data then traditional raid doesn't help. That is one of the big attractions of filesystems like zfs and btrfs that combine checksuming with redundancy at the same layer.

  11. Re:What about reliability? on OCZ RevoDrive 350 PCIe SSD Hits 1.8GB/sec With Standard Toshiba MLC NAND · · Score: 1

    Not really

    Another poster claims that ocz had an average return rate of 5%. Some people don't return their drives because they value their privacy more than the cost of the drives or because they can't be bothered with the effort of returning them and some drives fail after the warranty runs out but before they are too small to be useful so lets suppose the overall proportion of drives has a 20% rate of "failure before becoming too small to be usable". Lets also assume that failures are independent events.

    If my quick calculations are correct that would make the chance of exactly two out of three drives failing about 10%, it would make the chance of exactly zero drives failling out of 6 about 27%.

    So with realistic guesses about failure rates it's very likely that there are a lot of people out there who have had multiple OCZ drives die and also a lot of people out there who have owned a moderate number of OCZ drives and had none of them die.

    Sure but everyone knows or should know that sticking random metal objects in electrical sockets is a bad idea, neverthless many countries now require safety shutters to make it harder to do this. While I have heard of people making cables with two household plugs joined to a single higher power socket i've never heard of anyone selling them and those who do make and use them will know they are dealing with something seriously dodgy.

    Contrast this to the USB situation where using cables that have two A plugs with the power wires paralelled were very often included with USB hard drives with the obvious intent (sometimes even explicitly stated in the manual) that you would plug them into two USB ports to get more power for your drive. You don't want to create a situation where a user doing what they have always done with the cables they have always used but a new computer and drive fries stuff.

    The problem is there are a heck of a lot of standard violating USB cables, adaptors etc out there.

    Lets consider a hypothetical "USB high voltage" standard that was similar to the "USB power delivery" standard but worked with standard USB cables. Now suppose an end user takes one of those cables that has a second A plug with it's power pins connected in parallell with the main A plug. They plug the host plug into a "USB high voltage" source, the device plug into a "USB high voltage" device and the power plug into a conventional USB host port. The "USB high voltage" source and device negotiate 20V and fry the conventional host port.

    I'd say the opposite

    If the plugin is running in a tight sandbox it should be easy to modify the sandbox to send the video to somewhere other than the screen without the plugin having any way to detect that this is going on.

    Of course this way you will have to re-encode so there will be a performance and quality cost but it should be easilly doable and work for any website that uses this drm infrastructure.

    And if you do want to hack the plugin itself (to avoid re-encoding) I can't imagine it will be too hard to poke a hole in the sandbox as well.

    last time I checked it was also illegal to kill people like you do in most other games.

    Note that nintendo is primerally a maker of childrens/family games. That means that when considering what to include in a game they not only have to think about whether it will make the game illegal but about what it will do to the age rating of the game in various countries arround the world. They also have to think about what parents will think of it.

    Notice how in games for little children you tend to kill monsters instead of people and in games for mid teenagers if you kill people it's in certain situations where it's either accepted by society (e.g. war) or far removed from current reality (e.g. the enemies have been possessed by aliens). There are games where you kill people in a gangland setting but they have higher age restriction on them.
