  1. Sounds like VMware for PPC on Run Mac OS X Under Linux · · Score: 3, Insightful
    And it even says so in the FAQ, except that the author hasn't ever used VMware, so he can't be 100% sure. The first couple of screenshots look particularly similar to any PC running multiple instances of VMware...

    As for the questions asking why, I suppose it's the same reason you might want to run VMware on an Intel machine: develop/test for multiple platforms without rebooting; or get capabilities only available in one or the other without a reboot. What would be much more interesting to me is MOL (or equivalent) for OS X. Just like running Linux or FreeBSD under VMware for Windows, it would allow me to run LinuxPPC or maybe even NetBSD under OS X (Classic already takes care of OS 9, and probably better than this program could). And unlike the VMware on Windows case, my host operating system would be enjoyable to use. ;-)

    Give me a break. I know from reading many of your posts that you're a very thoughtful, intelligent sort of person. But I also know that you rush to defend the Macintosh platform at all costs, throwing that thoughtful intelligence to the wind if absolutely necessary. It's getting kind of old.

    The guy provides the most in-depth, unbiased technical review of Jaguar that I've seen to date. Overall his review is very positive and enthusiastic. But he also points out the things that still need fixing or improvement. As soon as you read that part, I'm sure your brain was thinking "Blasphemy! Must defend beloved, infallible OS!"

    Puh-lease.

    Sure, he gets a little nitpicky with a few problems that bother him personally, but the fact is that they remain problems that Apple needs to fix. You may not agree with everything he says either, but to dismiss the entire thing because he makes a few good points that expose weaknesses in your beloved platform is like walking around with blinders on.

    I absolutely love the Mac platform. Mac OS X is, far and away, the best OS I've ever used (out of all flavors of Windows, Linux, FreeBSD, IRIX, HPUX, AIX, Solaris, VMS, DOS, OS/2, BeOS, you name it). Like you, I tend to be quick to defend Apple and Mac OS X against FUD and damaging misinformation. Case in point: the graphic designer at my wife's job has to use dialup to get his email because the MCSE network guys said "Macs can't network." I hear that all the time - Macs can't do this, Macs can't do that - and have to correct it. Sometimes it's infuriating to see the ignorant biases against the Mac platform.

    But this particular review is very well researched and thought out - and accurate! The shortcomings he lists are, indeed, shortcomings. I really hope the engineers at Apple read every one of his reviews and take them into account - the next version of Mac OS X will be that much better because of it. Imagine that - as good as Jaguar is, imagine having something even better. Great, isn't it?

  4. Re:Put a screensaver on your desktop! on Quartz Extreme with Unsupported Video Cards · · Score: 1, Troll
    Cool trick. I was in an Apple Store on Monday and went around testing the performance of various machines using this. Of course the DP 1GHz suffered no noticeable lag compared to a static background. I was surprised to find that the 800 MHz TiBook showed no slowdown either. The iBooks were quite slow, and exhibited greenish box artifacts around all the windows while it was running. Although in regular screen saver mode, flurry ran great on them as well.

    Honestly, I think they ought to leave at least one or two machines in the store running this just to show how powerful QE can be. But as knowledgeable as they may be, I'll bet most of the salespeople there didn't know what happened or how to turn it off - other than rebooting. ;-)

    Wish I could have tried this on my 733 at home, but I'm still on 10.1.5 and it doesn't support the -background option. It would have been interesting to compare the difference between that and Jaguar, with and without Quartz Extreme enabled. Anyone know if this (-background) will still work with QE disabled?

    Their mission sounds quite a lot like that of my alma mater. In fact, the newest building at the time I went there was named after Olin, so I suppose it's no surprise that there's now a (similar) full college named after him. Personally, I highly recommend an emphasis on humanities in the otherwise technical curriculum, as I said last week.

  6. Re:Sun equipment on Exercise for Geeks? · · Score: 2
    the key to keeping weight down is to listen to your body and only eat what you need, not what you want.

    Sounds a lot like the Hacker's Diet, written by an engineer for engineers. In it, he uses the concept of an "eat watch," an imaginary watch whose alarm goes off when you've eaten what your body needs. People who are too skinny have eat watches that go off too soon. Overweight people have eat watches that go off too late. The trick is to compensate for a faulty eat watch by carefully tracking and adjusting what you eat vs. what you really need. It's the classic engineering problem of tuning a system with inherent feedback. I lost 35 lbs in 10 weeks on his plan - highly recommended.

    But since this article is about exercise, I'll also mention that he includes a very good exercise plan as a supplement to the diet. See the same page linked above. It's easy stuff that you can do without any extra equipment in your own home. Like the diet plan, it's very structured so that you always exercise at your level and can move up as you improve to increase the effectiveness of the workouts.

    That said, I still prefer getting out of the house over doing something inside. My wife and I walk in a park for an hour about 5 days a week, and I try to do at least something like basketball or biking on the weekends. Works for me.

    (just saw your reply, hope you see this a few days later...)

    Will OpenGL acceleration work for TVing bitmapped images?

    Sure, I actually do this to display maps of satellite data. The 2D image can be texture-mapped to a flat rectangular polygon in 3D space. What I do is set_plot to the internal z buffer and tv the image to that. Then tvrd() it and send the resulting image to the contents of an IDLgrImage object. If you're not doing anything between the tv and the tvrd, you can probably skip those steps and just send the bitmap to the image object.

    The biggest problem with Object Graphics, especially if you're used to Direct Graphics, is the steep learning curve. It's very different and generally requires more "setup" in your code, but once you have a scene defined, you can take advantage of OpenGL performance to manipulate it They have builtin plot objects, contour objects, etc. And if you have something that can't be done with their builtin objects, you can always use the technique above to render Direct Graphics stuff internally and display it using Object Graphics.

    Anyway I hope that was helpful (if not completely offtopic to the story).

  8. Re:Apple.... on Should "B" be the Same as "b"? · · Score: 3, Insightful
    Yes, the default in OS X is HFS+. Apparently UFS is much slower, and many Carbon applications have problems running from a UFS partition (I use HFS+ but have read this in many user reports). I'm not sure why - OS X handles resource forks on NFS filesystems by creating a ._File.Name file to hold the resource fork. I would assume it does the same for UFS, but I don't know. Or maybe some applications expected to be able to write to the same file using different capitalization. Don't know why they would be so sloppy, though.

    Back to the main topic, I agree with Apple's position on this. I used to wonder why they would put in such a ridiculous limitation when it would be so easy to "fix," but then I thought about it. There is absolutely no reason to have files named "readme.txt" and "Readme.txt" in the same directory. If they are truly different files, then name them differently - ie, "ReadmeFirst.txt" and "ReadmeLast.txt." Capitalization is mostly arbitrary and conveys no information in this context. It can only lead to confusion when a human has to interact with such files. Sort of like George Foreman's house, where his kids are named george, GEORGE, GeorgE, georgE, GeOrGe, etc. What a mess!

    If you're still not convinced, think of all the chaos and confusion that would happen if domain names were case sensitive.

  9. College is about learning to learn on Tips For Incoming 2002 Freshmen · · Score: 2
    My god, it's now been a decade since I was in your position, about to enter college. Still seems like just yesterday.

    Anyhow, the thing I really got out of college was not the information and knowledge I acquired, but the skills. And the #1 skill was knowing how to learn effectively. On a day to day basis at my job, I use little if any technical knowledge I learned directly in my college courses. What I do use are the skills and the knowledge that I've learned in 6 years in the industry. I've been able to impress my management with my ability to pick up new concepts and solve problems that had stumped others, so I've done fairly well in the raise department - but not because of the facts that I learned in college.

    If you can learn effectively, you can do anything you want when you get out of school. It doesn't matter so much what your major was, but simply that you got the degree and can show any prospective employers or clients that you can do the job they are looking for. The best people I work with are ones who didn't go directly in the exact field they majored in, but who sought jobs that would interest and challenge them, and that they knew they were capable of picking up.

    With that in mind, make sure you choose a major that interests you. Preferably also one that you'll excel at, or that you'll at least do ok with. Don't worry so much about what the job market will be in that field - 4 years is a long time and things can change dramatically (just think about people who graduated this year - they started just as the dot com bubble was starting to swell up). As I said above, if you can demonstrate intelligence, an innovative spirit, and both a willingness and ability to learn quickly, employers won't care what your specific major was.

    Along the same lines, don't stress about choosing a major too soon. Explore and take classes that sound interesting. If you stumble onto something that really excites you, great! By the same token, don't fret if you get into your upper division classes and start to lose interest. This happened to me as a physics major - I completed the degree but have no desire to go any further in the field. I concentrated on rounding out my education and diversifying my learning as much as possible.

    My alma mater was a science and engineering school that emphasized the humanities, and I'm ever greatful for that. I had to take more humanities classes that most science and engineering majors at other schools, and it significantly broadened my horizons. I ended up taking some really neat philosophy, music, history and other classes that I wouldn't have otherwise. The music classes in particular led me to expand my hobbies as an amateur musician after I got out of school. Whenever possible, take classes outside your major that sound interesting and that you might not otherwise take.

    Other people have already made some good comments about the non academic stuff. Make sure you have fun, take a break, get out of the dorm (and do live in the dorms - group study sessions were often lifesavers in those really tough classes), go to parties, exercise and all that. Take an extended break if you feel yourself burning out, but don't let it go too long. I can say after being in the "real world" for 6 years, I have little motivation to go back to school and get a graduate degree. I may do it yet, but it'll be tough.

    One last thing I'd say is that you get out whatever you put into your education. Yeah, it's a little clich but it's true. My wife's school seemed more like a diploma mill than a real school. The vast majority of the students were only interested in going through the motions to get a piece of paper at the end. It not only made things difficult for her in group projects where she did most of the work because they didn't care, but I think contributed to an overall attitude of apathy at the school. Most of her classmates got little to nothing out of their years there. Some of them acquired some knowledge, but I'd say most never got it, never learned how to learn.

    And unfortunately these people will probably be our bosses in the future... ;-)

    Have you tried using IDL's Object Graphics? It uses OpenGL directly and the performance is excellent with any decent graphics hardware. We use it on SGIs, Suns, and PCs with mediocre to good graphics cards and all perform very well.

I added one later, for cheaper than it would have cost me to get it preinstalled from Apple. The difference here is that the optical drive is user-serviceable in the tower but not in the eMac.

    Digital video. The MiniDV format (most popular for digital camcorders these days) clocks in at nearly 13 GB per hour. When you're trying to edit several hours of footage, space gets slurped up in no time flat.

    My wife and I bought a DV cam to record our wedding and honeymoon. We shot about 5.5 hours total footage and now I'm in the process of editing it down to 1/2 hour to an hour to make a DVD. We added a 120 GB drive to our Mac and the thing now has about 40 GB free. It will continue to lose space as I copy clips around during the editing process.

    Only real problem with such huge capacities is that backup media consistently lags behind. When I finish this project, there's no way I'll be able to backup all the source media as that would take 15-20 data DVDs. It's not so bad since I'll be throwing out a majority of the raw footage and can backup just what goes into the final video, but I'd hate to have 200 GB of data I really cared about!

Of course opening the box up and connecting a hard drive is probably too daunting for most home users, despite how easy the PowerMac's case is to open. But like someone else said, most people know someone with geeky tendencies who would be happy to help out.

    Furthermore, I don't think Apple is really trying to tell people to ditch their current, brand-spankin'-new PC for a Mac. It's more along the lines of "If you're looking for a new computer, why not make the switch and go Mac?" With that in mind, people have to transfer their files when they buy a new computer regardless of what type it is. The point is that it's no harder to transfer from PC to Mac than from PC to PC.
