    If you have a task that requires much memory then the RPi probably isn't the right tool for the job. 256Mb might be pretty spacious for an embedded environment explicitly intended as such, but it is a bit camped for a general purpose Linux system so chose your configuration with consideration.

    It'll depend what SD card you give it too - some write much faster than others, particularly when considering random access I/O loads like memory paging. Even the best SD card isn't going to be great for random access though as they are generally optimised for their most common use, storing images and videos for cameras and such (a predominantly sequential I/O load in either case). If you do need to swap you might find some USB drives perform better - I have one that can sustain ~17Mbyte/sec in sequential writing and I'm sure it'll best any SD card for random writes too (though I've not tested this - I don't use it in a way that needs much random access).

On top of BT/OR getting less income from areas like that, the nature of the area and how protective the people in it are of it means that working in the area is going to cost more to start with.

They've done their due diligence and the residents have forcibly opted out, they can now spend the resource working in a potentially more profitable area.

    Here is what I personally don't get, maybe someone can explain it to me, but WTF was it with RMS and the TiVo? It was ONE device that had NO choice but to be made the way it was.

    If it had not been TiVo it would have been something else. His problem was the use of GPLed software in that manner. While it wasn't found to break the letter of the license it broke the clearly stated spirit of the license, so that wording was updated in v3 to patch the hole.

    Would he have been more happy if it had used WinCE?

    Yes, basically. Or some form of BSD (the licenses used there would allow this sort of use IIRC). Or anything else not GPL licensed. They had those choices available to them.

    RMS is an absolutist on this and similar matters (some would say extremist, but I feel that label to be rather too strong here): if you want to use Free, keep it Free with your use, otherwise use something else (paying for it if need be).

    it just seems stupid to attack one specific corp

    He wasn't going after one specific corp, just the first one that did it (visibly) first and shoring up the hole before others tried. Remember that TiVo could keep using GPLv2 software as they had already done, they'd just have to start maintaining by other means once later versions switched to GPLv3, so the switch to GPLv3 did not explicitly stop them distributing their product.

    and make other businesses afraid of being next on RMS' shit list and all over a device that frankly could have been made no other way without only being sold at China Mart and other "pro piracy" hardware sites.

    That is where it falls down of course, but so does every other license commercial or otherwise - if you can't enforce the license in a territory people wanting to do something against the (letter of the) licence in that territory are at an advantage to those elsewhere. "Pro piracy" regimes are not a GPL specific problem and not really relevant here - you could just as easily state that VMWare's recent licensing model changes are an attack on compliant companies.

    There are many people who think RMS is wrong on the matter, of course. Linus for instance still explicitly uses GPLv2 as evidenced by it being the license git is released under (the kernel is a different matter: that could not be switched even if he wanted because of how many contributions there have been where rights were not explicitly handed over to the project).

    It is a case of choosing the right tool for the job. Until recently their choice was to redefine the job (change the parts of their projects and licensing policy that GPLv3 conflicted with), keep the old tool (using older, GPLv2 licensed, releases of GCC only), or use something less stable/proven/compatible. They chose the middle option. Now option three is replaced by "use something else that is now stable/proven/compatible enough to be an alternative" they have taken that choice. Again this isn't complaining about GPLv3, it is simply refusing to use it because it is incompatible with some of their chosen goals.

    I'm told there are technical reasons why Clang and the related tool chain are preferable to GCC in some circumstances too, though I'm out of the loop on that one so I don't know what they are or if they are significant to FreeBSD.

    While his answer was rather terse and it would have helped to be less so (it made him appear to some, to you at least, like an anti-GPL troll), what you appear to have done in your response is set up a strawman to attack. This is the sort of thing that anti-GPL people (both within the open-source arena and external to it) will jump on as "proof" that GPL advocates are rabid loonies, so by defending the GPL in such a manner you may be harming the cause rather then helping it. You might want to be more careful not to come across that way (it may not have been you intention on this occasion, but it does seem that way by my reading).
