    As for the DNS:

    if you have DHCP, it should take care of this...
    if you dont have it, zeroconf/bonjour/avahi or any other service discovery should take care of it, any modern OS have this, most of then enable by default

    if you have neither, how would you do with ipv4? remember the IP? fine, you just have to remember the network address in ipv6, the rest is the MAC address you can check anytime or setup a static local part, like maybe (network address)::1

    Exhibit A: DHCP do helps workstations, but how about print servers, servers and apps? yep, "static" is easy to fix, finding the apps that refer to the old static IPs is hell... yes, apps should use ALWAYS DNS, but some devs and admin are plain dump and breaking the service and finding this corner cases will take 90% of the time of the merge changes

    Exhibit B: some VPN helps managing this NATs, but start having more VPNs and more network colisions and again you have hell managing all those NATs and endpoint addresses

    NAT is a useful patch for ipv4, but the more you use it, the more problems you will have... many stupid apps (from big companies) like to include the real IP in their internal protocol, breaking all the NAT config. filtering and logging on the apps side in NAT environments is again pure evil, you can only use the router/NAT filter or higher level (like username/pass, but you lose the possibility to limit a user/pass to a certain IP)

    IPV6 dont need NAT, people that want it dont really understand IPV6, they just want another easy patch to extend ipv4 so they dont have to learn something new

It never occurs to them that *other* people might be quite happy to apply torture without any issues at all and just see it as their duty to protect everyone.

    see... it also sound bad... unless you are ok with torture or if you are Jorge Bush

    The problem with closed drivers and apps is that they don't affect just you, they affect everyone, just like the torture.

    If fully permitted we will get a mess of closed drivers, full of bugs and incompatibilities (see windows drivers) and no incentive whatsoever for hardware builders to release open drivers, propagating bug and problems that anyone can fix. Every driver would need to be reverse engineering, taking too much resources and time... Linux would still be in 2.0 probably, not even talking about *bsd, BeOS, OpenSolaris, etc... those would be without any driver unless those reserve engineered

    Your freedom stop where the other people freedom start, you CAN use whatever close source drivers you want, do whatever you like in your machines. Other choose otherwise.we lose games? its sad, but i prefer having a stable and fast platform, games will came sooner or later.

    ps: there are already many native, funny linux games, you just dont have the main, blockbuster ones.

LSB specially need to work better and not just think in server, but also for user. Create something like directx package, where several standard tools and libs for video, network, sound, input, etc exist and check all the requirements for games to use then... it helped a lot the games in windows (before directx, windows games also had to battle each one with all the apps and libs)

    ati closed drivers arent crap... sure, nvidia drivers are better, but both have many stupid bugs and limitations,

    nvidia replaces most Xorg features, where ati ones tries to play support then... but that creates problems too, example: xrandr have its own limitations, where a alternative method (nvidia) can fix then

    performance wise, nvidia have closer performance in linux as it have in windows, ati there is a drop in performance, where some can be pointed to ati fault, other to the Xorg layout and support libs

    so you have this:

    closed, re-implements everything to get better performance and bug fixed, even if that cost new features -> nvidia
    closed, tried to reuse Xorg features and layers, and so have its own bug and performances caps -> ati fglrx
    open, uses all kernel and Xorg features and layers, needs to mature to get better performance -> radeon driver
    open, uses all kernel and Xorg features and layers, needs to evolve and mature a lot more -> nouveau

    so the top is higher performance, the bottom is lower performance and features... for me, ATI is perfect, if you need performance, go for the fglrx driver, if you need features and open (like me), the radeon is good enough.

    on ATI you have the choice, in nvidia, the choice is made for you

    better resume:
    games -> nvidia then fglrx
    desktop usage -> radeon, then intel, then the closed drivers

    i think that the major problem with the fglrx drivers is that they take too long to be developed/test/released ... i guess they are missing man power and that limits the bug fixing performance tuning effort.

    As for wind generation, wind requires towers, and if you put one up next to every house

You dont have any dams? use the energy to break water in hydrogen to later burn...

    Is there a need for other ways of energy source? sure! until there are enough and more efficient cleaner energy production, old methods must be used... from the article, 40% of Portuguese energy come from green sources, the other 60% from oil and gas (no coal there), but because of this, no more unclean power plants are being build and some might even close.

    Nuke is very powerful, but too expensive, even before the waste treatment and storage... add that and you see its not really a viable option. The problem is that the pro-nuke never thing about the wastes, its future generations problems, not theirs

    the smart man's mantra is renewable energy... big installations are good, but the future is small, local area installations. If all the houses had wind and solar generation, the outside energy needs would be small and a lot easier to manage. Of course, freezing winter can still be a problem, but those could use other energy sources like biomass and biofuel.

    what is needed is a merge of all technical advantages in solar research and mass production of solar cell and wind turbines, so the price drop and efficiency rises. Instead of giving government aid to oil production, give it to the green energies and watch things grow. Germany gives big bonus for solar installations (and remember that they have a lot less sun hours than south Europe countries) and now Germany have more solar installations than the south Europe countries and made the solar cell price drop hard and build a new industry.

    The problem is always the same, oils is cheap, other ways are more expensive, but without investment the new energies cant drop price and oil prices (and taxes) can only up in the future
