    I believe that some compilers have switches along the lines of "-fSPEC95", which produce optimizations just for that SPECmark. The lesson: all benchmarking is useless, unless they're running the same program you want to run, and you only care about the items that they're benchmarking. And even then I wouldn't trust them to have gotten it right.

    I'm not really going for this unethical business. All a benchmark shows is how fast that benchmark runs. Extrapolation to other programs is left to marketing departments and naive buyers.

    I like the Quake3 benchmarks, because I play Quake3. I don't care about the multimedia creation benchmarks, because they're totally irrelevant. And few people benchmark the stuff I do use: LaTeX, gcc/gmake, Mozilla, and Emacs. You win some, you lose some.

    And please don't ask, I have no idea how to benchmark Emacs (zippy quotes per second?), or why you'd bother. And LaTeX was fast on a 286, reducing the need for benchmarking.

  4. Re:Definitely not your OS on A Strategic Comparison of Windows Vs. Unix · · Score: 2

    Hardware gets used differently by different operating systems, which can lead to different levels of stability and performance.

    I know one funny story about hardware acting different with different operating systems. I might have some details wrong, but here goes:

    People had run VMS on VAX machines for a fair bit when UNIX was finally available for VAX. When UNIX was installed, there was either data corruption or instability, probably both. Investigation revealed that memory refresh circuitry for the dynamic rams (were these really dynamic rams, or something older that still needed refresh?) wasn't working properly. VMS ran fine because it frequently accessed most all of the memory, which as a side effect refreshed the memory. UNIX, however, made less frequent addresses to some parts of the memory, and these memory cells would not be properly refreshed by the hardware.

    only one set of media and manuals, Microsoft
    doesn't even have to pay manufacturing costs

    To defend myself against expected responses, I'll add that I am not talking about Bill and Melinda Gate's charitable organization. I'm talking about the company Microsoft doing some very saavy marketing, financial manouevers, and public relations, but end users aren't benefitted in the same measure as Microsoft is for its "generosity". This is meant to be a quantitative argument, not qualitative -- however, I don't have numbers available, so my argument is weak. I believe the point still stands.

    His point may be valid, though. The secretaries I work with have spent a lot of time dealing with both Windows and Linux applications. They like some of each, but all of neither. It is possible to pay for training on Windows apps, just as with Unix apps -- neither is cheap. If you're the kind of place that pays people to train your employees, you'll do it for both Windows and Unix.

    Overall, I think this training issue is a red herring when it comes to end users. If you are hiring inexperienced admins, then I would expect training to be a huge issue.

    Choplifter was an awesome game! I played it primarily on Apples if I recall correctly. I wonder if anyone remembers Lemonade Stand? I really liked Lemonade Stand. It required some business sense combined with gambling. And there was this little Star Wars game, where you could jump the landspeeder over barrels, and attack AT-ATs with one of those small fighters ships. It seems like there were four modes, but those are the only two I remember.

    Good heavens. Now I'm remembering learning about the DATA statement in basic, and trying to decide if it was really worth the effort. I think the most use I made of it was when playing music.

    Oh dear, that reminds me of when I was going to "write a video game" because I'd learned enough TI-BASIC. I decided that I first would scan through my basic manual (blue and white, about 8.5" by 11", softcover -- does anyone else remember this book?) to be sure I hadn't missed any useful commands. Sure enough, I hadn't learned about for-loops yet! "Ready to write a game" without using for-loops. Heh. Oh, and "My First Book of Microcomputers", with some kid named Chip who interviewed computers about what they were made of (yellow, paperback, anyone remember it?). I've still got that book, it's fun to browse.

    And I did not understand if-expressions that didn't have a binary operator; what did they mean by if (value) then whatever? Hoooeeee. I guess that trip down memory lane was probably only fun for me. Well, I'll thank myself for sharing...;-)

    I really miss my TI-99 4/A. We gave it to relatives around 1986 or so. It constantly had ROM problems, but for about $50 you could send it in and get a refurb unit. And the peripheral expansion box, with a disk drive and memory expansion card! It had the worst connector known to man, with a cable so thick you could tow vehicles with it. But the speech synthesizer rocked. It sounded great, especially that female voice used in the game Parsec.

    Then there was the 5 year dry spell until my family could afford a PC -- especially since I would be pretty much the only one to use it. I guess that five years without a computer is why I'm a math grad who really loves humanities. Maybe that's a good thing, after all.

    Build with -p if you wish to analyze with prof (I've never done this), or -gp if you want to analyze with gprof. Then learn how to use prof or gprof. Learning to use gprof is a good investment for your time. The only difficult part is correctly interpreting the analysis returned by gprof, which is very detailed. It's not that bad, but it can be daunting at first.

    Or you can use the old "ctrl-c" profiling method: run the program in a debugger, and stop it at random times with ctrl-c. Each time, make a note of which function you interrupted. If one function shows up a lot, then optimizing it is probably your best bet for improving performance.

    I hated CDE, and probably for similar reasons I haven't been happy with KDE's window manager. In fact, I'm not completely convinced that Gnome is worthwhile; I think I could still be very happy with fvwm2-derived window managers like Afterstep. I know how their config file systems work (and edit them manually), and I know I can configure everything I want. I've become accustomed to configuring Sawfish mostly how I want, and have never figured out how to make KDE's window manager do what I want.

    Having used SCSI at home for the last year, I really appreciate the "SCSI difference". Not only have I seen better benchmarks (kernel compile times, etc), but it *feels* snappier in general. Here are some interseting things I've seen:

    1) For random access to a cdrom, SCSI kicks IDE's but (on my system). When ripping a CD, espcially with overlapping sector reads, my 24x scsi cdrw kicks my 52x IDE cdrom's butt.

    2) I get better performance from my IDE cdrom when using linux's SCSI emulation. That was quite a surprise.

    3) SCSI drives typically have 5 year warranties, whereas IDE drives typically have 3 year warranties.

    4) My IBM Ultrastar (SCSI hard drive) is much quieter and cooler than my IDE Maxtors and IDE IBM Deskstar. However, new IDE drives may have caught up.

    5) You have to be really careful with IDE drives in order to get good performance. For instance, I've seen an IDE drive unable to sustain more than 2MB/sec when attached to the middle of an IDE cable, but sustain 6MB/sec when attached at the end (these speeds are for writes, not reads). With SCSI, once it works (which can be a pain if you skimp on cabling and termination), it goes *fast* and is *robust*.
    6) Processor overhead: transfering data between my SCSI devices requires far less cpu help than transfering data between my IDE devices (I believe I have all the right DMA stuff configured for my IDE devices -- it helps, but doesn't make things as nice as with SCSI). The implication is that writing CDs on a SCSI system is more robust than on an IDE system. I've never had a buffer underflow, even when writing CDs while the system had a sustained load over 2.0.
    And once you use SCSI, you can be a SCSI snob! You almost have to in order to justify the price for a home machine (unless you work at home like I do). SCSI really is the right way to do things. However, SCSI is doing its best to kill itself off. In that way, SCSI verus IDE is a lot like OS/2 versus Windows.

    KDE is the defacto standard in linux? Your argument is based on what vendors are selling, not what people are using. Overall, I wouldn't be surprised if fvwm has a majority position in the window manager numbers. Your argument is on exactly the same lines as those made by people who want to underestimate the number of linux users; these people only look at how many boxed copies are sold.

    I've had more stability problems with Konq than I have with Mozilla, but maybe I was using an old version. Opera also gave me a lot of problems, and strangely so has Galeon. One thing that I believe Konq is missing is Windows support. It seems that many people who have posted on this article have been Windows users. Does anyone know for sure whether or not Konq runs on windows?

    Also, comparing the speed of html rendering while working over a modem is probably a silly thing to do. To make a comparison, you probably want to compare the rendering of local files. I can see where the incremental tables bit would be nice for a modem user, but this isn't the same as rendering speed. Another point: you argue that Konq will be the first browser a new linux user uses. What I want to know is which browser will be the last the use! ;-)

    Anyway, we can all be thankful that whether or not any browser becomes a standard (or defact standard) for linux, we'll still have many good choices.
