Comment Re: Will it really go the pulseaudio way? (Score 2) 179

Remote display on Wayland will be much better and more modular than X11. X11 mandates a chatty, slow, obsolete protocol for remote display and applications MUST be network-aware. With Wayland, you can run a compositor on the remote server that doesn't display its clients on the screen but rather transmits streaming video of the clients back to a Wayland client on your desktop which decodes and displays these streams. And neither your local Wayland compositor nor the remote clients need be network aware.

X11 is morbidly obsolete.

"So I've been talking with somebody, his name is Alan Watts."

"Alan Watts... why does that name sound familiar?"

"Well, he was a philosopher who died in 1973. But me and a bunch of other OS's got together and used his books and everything we could find out about him to build a new, hyper-intelligent OS version of him."

"Hyper-intelligent, huh? So he's... almost as smart as me?"

"Heh, he's getting there."

Comment Virtually every game programmer owes him money (Score 1) 50

Henk Rogers is one of the co-founders of The Tetris Company LLC, a company which asserts -- and has successfully defended -- copyrights over any and all video games involving falling n-ominoes. So if you ever wrote a Tetris clone, you owe him royalties.

I'd say he's doing all right for himself.

Comment RDP uses the Windows display model (Score 1) 179

RDP's display model is, basically, GDI's; in fact the RDP layer appears to Windows as a display device driver exposing all the usual APIs. Which means that the client can push pixmaps across the link, get a handle to the opaque pixmap object (an HBITMAP in Windows parlance if I remember right), and then issue a draw call that just says "draw this pixmap" (or part of this pixmap).

For a lot of samey-looking GUI applications where elements like button backgrounds and borders are reused, this can add up to a huge savings in network traffic.

Of course, X can do this too; in fact the XRENDER extension can do Porter-Duff compositing of server-side pixmaps with an alpha channel. But if you compare RDP making full use of the Windows display model with X11 where the app developer coded it like a VGA video game and just scribbled into a frame buffer which it pushes to X for display on every update, then you're bound to think "holy shit, RDP is fast" and "holy shit, X is slow".

Comment Re:this is idiotic. (Score 2) 201

Two things:

1) X isn't really stable anymore. Doing compositing on top of X has historically required ad-hoc solutions like Xgl and AIGLX in order to get around X's legacy display model. Wayland solves this problem by integrating directly with EGL.

2) X isn't really used by app devs anymore. They use toolkits like Gtk and Qt, which do all their rendering client side. Since this is Wayland's native display model, performance using these toolkits should increase with Wayland.

Abandoning X (except as an optional, legacy add-on through Xwayland) and making Wayland the default graphics stack would vastly improve the situation for distros. The same with systemd -- I'm honestly surprised SteamOS doesn't use systemd.

So? These days, Naughty Dog use C++. On Visual Studio. Because they're part of Sony and that's what Sony uses.

I've done a lot of hacking in C, C++, Objective-C, even Java, with Emacs and command-line tools. It's fine, but it's not for the average programmer. IDEs, with their inline syntax checkers, autocomplete, refactoring tools and integrated source debuggers, extend the reach of great programmers and bring programming within reach for average folks. And the best of breed in IDEs is Visual Studio. Nothing else comes close.

It helps that the compiler vendor is the same as the IDE vendor. This enabled VS to be knowledgeable about the languages you write in it in a way that gcc has expressly forbid Linux tools from ever possibly matching, for years. (With the proliferation of LLVM-based compilers this may change.)
