  1. Re:Carmack and the Mac... on New Doom Details · · Score: 2

    I've noticed a bit of an increase in Mac ports of big-name games and an increase in advertising for them in Mac sections of ads from CompUSA and the like, and coincidentally(?) I've noticed this spike since a couple months after Carmack started praising the Mac as a game dev platform. Has anyone else noticed this, or have I killed too many brain cells and am now just imagining it? I'm curious as to what others think about this, and how others think Carmack's support might be positively affecting Mac gaming.

    Actually, I think it is Apple who have been pushing Mac gaming, and Carmack is just one (significant) part of that. For years Apple was neutral or even openly hostile towards games on its platform. Since Jobs returned and the company has become more consumer-oriented, there has been a concerted drive to get more games developers onto the platform. The number of games ports onto the Mac has increased dramatically, as you have noticed.

    Certainly wooing Carmack to the merits of the platform has been a big part of that strategy, but so has the general push to help all game developers. It has also helped that Apple has bought better game-related hardware to the Mac, both directly and through third-party support.

    How many guesses do I get? ;)

    Bet you can't guess. Not that I'll confirm it, even if you get it right . Sorry :-).

    Anyway, your statement borders on meaningless. Do you mean parser when you say interpreter? If so, do you just mean getting the document into a data structure?

    No, I meant interpreter - parsing is just one step, you then have to actually execute the semantics. in other words, take a Flash description file and actually run the resulting interactive animation. Same for the XML descriptions we were interpreting.

    In my experience, custom binary formats are usually easier to parse, because you know exactly what to expect (assuming they're documented, of course), and they end up being mostly follow-your-nose exercises.

    In theory perhaps, but once you've got multiple versions of the format that you have to deal with it gets much hairier. And often custom proprietary formats are very poorly documented - often the code is the documentation, and if you don't have the code...Besides which, something like Flash is sufficiently complex that it becomes quite a challenge in its own right.

    Whereas XML is (obviously) much more flexible, resulting in more possibilities for the parser to handle. On the other hand, binary formats (being typically less eXtensible) can get ugly more easily, so I can imagine that Flash might be a pain.

    Yup, Flash is a pain. And with XML you often (as in my case) don;t have to deal with the full potential of the language, just some known and bounded sub-set. I would guess that SVG is like this, but I haven't looked into it in enough detail to really know this.

  4. Re:Its Text, Not Binary on Scalable Vector Graphics Format Candidate Released · · Score: 2

    The big problem with SVG is that it is text and not binary. This means that a graphic will be bigger in SVG than Flash.

    The fact that is is a text-based (actually XML-based) format is a strength as well as a weakness. Yes, it tends to be bigger than Flash binaries, but its open and extendible whereas Flash is a closed, proprietary binary format controlled by Macromedia. Its a bit like comparing HTML with the page description languages used internally by desktop publishing apps. Which one was better suited for creating the Web? Which one would you rather work with?

    Also flash can be compressed, and SVG cannot making the difference bigger. Think those 100k flash animations are annoying to wait for loading? I can only image how big the SVG equivelents will be.

    Text can be compressed, and will usually compress better than binaries. Why? Well, think of the XML text as source code - compilation into binary is a form of compression, so binaries are already compressed (therefore they won't compress well themselves). A text file is likely to be inherently more compressable. Has anyone actually tried compressing XML?

    The problem with this popularity contest is that the majority have never really been given a choice. If one had set a CLI and a GUI side by side and said "pick which one you want" then you would have more of a point. But the majority haven't been given so objective a test. It has been more "this is what you'll be using from now on", and the alternative either is briefly (footnote) mentioned, or not at all.

    True enough. What I was actually thinking of was the switch over from DOS to Windows in the late 80's/early 90's. A lot of people voted for a GUI over a CLI with their hard-earned greenbacks. And that was to a pretty crappy GUI (admitedly from a pretty crappy CLI :-) Of course there were other factors involved as well, such as upgrading of applications, but I do believe that a preference for GUIs over CLIs was a large part of this. If we were on DOS 15.7 right now, I don't believe there would be nearly as many computer users in the world.

    Obviously a CLI like bash is going to be more efficient at expressing the commands for 1. But assuming that the files related to my web site are not organized according to a regular pattern, then doing operation 2 is going to be much easier using a GUI (I just click on the set of files I want and drag them)."

    Assuming no organized pattern then both methods would be slow. Remember the brain is a pattern-matching machine, be it verbal,graphical, or otherwise. If their is a pattern then the deciding factor of one over the other is what comparative sense is being used. .

    I agree, but if I want to identify three files from 50 in a GUI, all I have to do is find them in the list. If I want to do that in a CLI, I have to find them in the ls list, then copy each filename down into the cp command. Its more work that way.

    Why be so offensive? Are you simply trolling? File Managers are not signficantly less powerful than CLIs.

The former tend to prefer GUIs, the later CLIs. The fact that GUIs are considerably more popular than CLIs is some evidence that more people are visually-oriented than verbally.

    I disagree. Two scenarios:

    1. I want to move all the files that end in .txt from directory A to directory B

    2. I want to move all the files whose contents relate to my web site from directory A to directory B

    Obviously a CLI like bash is going to be more efficient at expressing the commands for 1. But assuming that the files related to my web site are not organized according to a regular pattern, then doing operation 2 is going to be much easier using a GUI (I just click on the set of files I want and drag them).

    Even when there is a regular pattern of files you want to work with, a GUI can often be easier (if less efficient) because I can just select the files I want directly, and I don't have to go through the cognitive process of forming the right pattern-matching command. If I want to pick 3 files out of 50, it often feels quicker to just click on them in a GUI view, than figure out the particular command that would select just those files. And in UI what feels quicker is often "better" (i.e. prefered by users) than the actually optimal strategy.

    GUIs and CLIs are different tools that are optimized for different purposes. Both have strengths and weaknesses. I personally like to have both running and feel free to switch between them.
