You do realize that the 'N' in 'NX' does already stand for Nintendo? :facepalm:

I've never seen anywhere say what NX officially stood for, usually it was refered to as 'the NX' or 'Nintendo NX'.

I've tried to it look up and the closest I found was that the current CEO doesn't believe there's any meaning behind it.

"As for the codename NX, I don't believe that there's any real meaning behind it, and to be perfectly honest, I don't know where it came from," says Kimishima, laughing when I ask. "Or perhaps Mr. Iwata had meant to tell me and then never got the chance."

Possibly NX Relocatable Object, similar to CRO on the 3DS. Basically, dylib/so/dll. We'll know more in the coming months, though.
I would not be surprised if Switch used position-independent executables for the main game executable in addition to libraries. That's been the standard on Windows since Vista¹, and has been slowly trickling down to Linux distributions. (Ubuntu 16.10 is fully recompiled as PIE.)

PIE makes runtime attacks somewhat harder, since the executable base addresses aren't fixed. There are ways to work around it, though.

¹ Technically, Windows doesn't actually use PIE. Executables are compiled with a fixed base address and a relocation section, which allows the dynamic linker to randomize the base address. Most other OSes do use PIE, though.

    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

  • SylverReZ @ SylverReZ:
    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".
  • Veho @ Veho:
    It's a DS Lite in a slightly bigger DS Lite shell.

  • Veho @ Veho:
    It's not a Nintendo / iQue official product, it's a 3rd party custom.

  • Veho @ Veho:
    Nothing special about it other than it's more comfortable than the Lite
    for people with beefy hands.

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme
  • The Real Jdbye @ The Real Jdbye:
    but that's a long shot
  • The Real Jdbye @ The Real Jdbye:
    i think only the red mario kart edition phat was v5
  • BigOnYa @ BigOnYa:
    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."

    lmao
  • BakerMan @ BakerMan:
    anyways, we need to re-normalize physical media

    if i didn't want my games to be permanent, then i'd rent them

  • BigOnYa @ BigOnYa:
    Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.
  • AncientBoi @ AncientBoi:
    I don't pirate them, I Use Them :mellow:. Like I do @BigOnYa 's couch :tpi::evil::rofl2:

  • cearp @ cearp:
    @BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.

    The issue is DRM
  • cearp @ cearp:
    You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60

    :rofl2:
  • cearp @ cearp:
    still, I agree physical media is nice to have. just pointing out the issue is drm
  • rqkaiju2 @ rqkaiju2:
    i like physical media because it actually feels like you own it. thats why i plan on burning music to cds
  • cearp @ cearp:
    It's nice to not have to have a lot of physical things though, saves space
