  1. amounts of caffeine in various products on Best Way To Beat A Caffeine Addiction? · · Score: 1

    Like many people, I also kicked the caffeine habit, years ago in my case. I used to get bad headaches now and then, and didn't know why, until eventually I realized it happened when I happened to go without caffeine for a few days. I decided I'd better either have caffeine every day, or give it up (in my case, I used to drink iced tea pretty much all the time).

    After years being mostly caffeine-free, I'm terribly sensitive. If I have a can of coke today, and a can tomorrow, then I will almost certainly get a headache the day after.

    I really love chocolate, but limit myself to just a few bites a day. If I have more than that, and then lower the amount again, I get a headache.

    I don't mind, I just have to be careful about what I consume. And I make sure I only buy headache medicines which are caffeine-free, otherwise, it just postpones the problem but doesn't really help in the long run.

    When I travel in China, sometimes it's not easy convincing people that no, I really don't want to drink tea. (And I do like tea, so I'll have it once in a while, but I really have to be careful to space it out, just once every several days at most.) Chinese people are so polite, and they think I'm just being polite, so I really have to explain that no, it'll give me a headache, which they often think is just crazy.

    By the way, a friend of mine who knows about my sensitivity to caffeine cut out a little chart from a box of herbal tea she had, which I have hung onto since then, since I found it interesting. It shows the rough amounts of caffeine in various things, in milligrams per 8oz cup or equivalent:

    herbal tea: 0 (of course, that's why they put the chart on their box of herbal tea)
    decaffeinated coffee: 5mg
    chocolate bar: 25
    antioxidant green tea: 30
    cola: 45
    drip coffee: 90
    double espresso: 160

    Take it with a grain of salt, but there it is.

  2. Re:25 hour cycle? on Living on Mars Time · · Score: 1

    Ever since I was about 10 years old and heard about those experiments of putting people in caves to study their natural time cycles, I've always been interested in participating in such an experiment.

    The closest I came was when I was an undergrad, spending summers working at Los Alamos National Lab. I was doing some computer work, and my boss didn't really care what time of day I worked, as long as I did my stuff. So for about a month I stopped paying attention to clocks and schedules. I'd sleep when I was tired, until I woke up naturally. Go in to work, and when I felt like I'd done enough, go home. Fortunately there was a 24-hour supermarket nearby, so I could do my shopping at 3am. My apartment had heavy curtains, so I could keep the place pretty dark when I wanted to sleep, even if it was sunny outside.

    I ended up on roughly a 25-hour day, although it varied. It was really quite relaxing. It was a little odd though, when my boss came in to the office at 7:30am and saw me there, he wouldn't know if I was just getting started, or about to go home.

    I wish I could do it again, but now I'm teaching classes, I can't exactly do that on my own schedule.

  3. Re:hmm on Why Personal Websites Matter · · Score: 3, Interesting

    What does make me wonder is why the obscure page with a few oddball pictures of myself gets more hits than the whole rest of that section combined (or for that matter, how they get to it without going thru the main site).

    If you are able to look at the referrer logs from your web server, those questions would be answered. It can be pretty amusing, by the way.

    When I was at Cornell, my web page mentioned that I lived in "beautiful Ithaca, NY", and that I worked on "mathematical models in biology". I found that some people ended up at my home page after searching for "beautiful models".

    I also wrote a children's story about a monkey, and had some info about it on my web page, along with pictures of a magazine it was published in. By far the most popular way people found my web pages was via searching for "monkey pictures", it's mind-boggling how many people were searching for that. But this was my favorite. You know how with some search engines you can search for some terms, but exclude others? Well, one person found my web page after doing a search for "monkey pictures", but excluding "sex"! It really made me wonder what they had found before, that caused them to add that exclusion term...

    There have been many disappointed people coming to my web pages over the years (yeah yeah, 'cause my web pages are crappy, right?)

  4. Re:"anonymous usage statistics?" on Belkin To Offer Firmware Fix For Router Hijacking · · Score: 1

    My problem with D-Link di604 routers is they time out idle ssh connections after a while. E.g. I stay logged into my office machine from home (going through the di604 at home) via ssh. After a while, the ssh connection gets closed.

    It used to close after about 15-20 minutes. After I complained to them, their next firmware upgrade increased the timeout to several hours, but it still times out. WTF? If I want a router to time out my connections, I'll tell it that's what I want. Since then I've unplugged the di604, and have gone back to using an old 133MHz Pentium running Linux as my firewall/router.

    I hated touchpads for pretty much the same reasons as you. I loved the little eraser-head pointer control on my old Toshiba. But my school recently bought a Thinkpad T-30 for me, which has both the trackpoint and the touchpad. I figured I'd never use the touchpad. But it turns out that's almost the only thing I use now; it's hard to say exactly why, but somehow IBM has "gotten it right" and made the only touchpad that feels natural to me.

I never even knew there was an arcade model with a joystick until now (as one of the links indicates, the Taito version had a joystick; the Midway version only had buttons). I think I prefer the buttons, but probably only because that's what I was used to.

  11. Steering wheels on Microsoft Stops Making SideWinder Peripherals · · Score: 1

    The only steering wheel I like is the Thrustmaster Nascar Pro Digital 2. It's not force-feedback, but it has a great solid feel to it, much better than others I've used, although they're somewhat hard to find. I've got a couple, and also got one for my dad to play racing games with.

    The last one I got, the brake pedal wasn't mounted on its potentiometer correctly, so I had to pop the cover off and spin the dial a bit before putting it together again, but it works great now too.

  12. Re:Incomplete DVD Set on Indiana Jones To Arrive Again in 2005 · · Score: 1

    As others have said, you can always buy the unboxed movies later on, unless you are such a collector that you really need the complete set in a box (and if you are that much of a collector, I guess you should have all of the boxed sets anyway, right?).

    I am more annoyed by the growing trend of rereleasing movies with more extras. E.g. I bought Terminator 2 and Dances With Wolves on DVD more than a year ago, and now it seems both of those have been rereleased with more extras (e.g. extra footage for Dances With Wolves). I don't want to pay to buy the whole movie again, just for those extras, but I would like to see that stuff. I wish they'd just decide on all the stuff they're going to put on the DVD, release it, and be done with it (although I can understand them rereleasing "historically important" films decades later with more stuff, that's a different situation).

    According to a Chinese friend of mine in Boston, even many Chinese people are worried about SARS in Boston Chinatown, and thus avoiding the area somewhat, which surprised me. (Unfortunately, I wasn't terribly shocked when I heard that some Americans were avoiding Chinese restaurants in general because of fear of SARS.)

    I have to admit, I was scheduled to spend about 6 weeks in China myself from May-July, but cancelled because of SARS. Not really out of fear of getting sick, but more out of concern about being stuck in my hotel for most of the trip, since universities are being pretty strict about who can enter and leave campus; and even some parks have closed. Most of my co-workers seemed more concerned about the possibility that I'd be quarantined for a while upon returning to the US. Personally, that wouldn't bother me so much. :-) Heck, I practically quarantined myself for a pretty good stretch of time while finishing up my PhD dissertation.

  14. Gauntlet is good on Two Players, One Console, Cooperative Play? · · Score: 1

    I agree, Gauntlet is good. My girlfriend and I played through it on the N64 a few years ago, now we're going through it on the PS2. She's not that great at games (although she did get pretty good at Mario Kart 64 after we played it for hundreds and hundreds of hours :-) ), and I like the mindless slashing and exploring in Gauntlet. Plus there are a few pretty funny things in there, such as when you find the egg -- "Red Warrior is now poultry" and you turn into a chicken running around squawking.

    And also, like others, we have enjoyed some 1-player games where I'm doing the controlling, but we're both figuring out what to do next.

    Also like others, in Mario Kart 64, we'd do competitive racing, but promise to try not to hurt each other, and only to hurt the other computer players. We are really looking forward to the new Mario Kart for Gamecube.

    I like simple games, and simple driving games. One of my favorites is Midtown Madness (1 and 2) for PC. I've finally got 2 decent PC's running Windows set up in my apartment, and 2 steering wheels, so I'm hoping to start doing some racing with her, although I expect it will take a while for her to get the hang of that. (I bought Midtown Madness 2 and a steering wheel for my dad after I bought my parents a new PC 2 years ago, since my dad used to race real cars. I finally did network racing against him last month when I brought my laptop and steering wheel home, but was fairly disappointed because I totally kicked his butt).

But I think you could apply some insights from (evolutionary) ecology to areas such as genetic algorithms, e.g. things like Danny Hillis' paper on using coevolving parasites to improve efficiency in searching for a minimal sorting network (there was a paper on it in the second Artificial Life conference proceedings way back around 1990 or so).

    I'm an applied mathematician (mathematical biologist) and use a very similar set of tools:
    • Matlab for code that isn't too computation-intensive, and for visualization. I like Matlab's "pcolor" function to plot a raster image of a 2-D array (unfortunately Octave couldn't do that last time I tried; I used to use Gnuplot all the time, but outgrew it when I started wanting to plot these 2-D raster images).
    • C code for the big simulations that involve trillions of random events. In some cases, Matlab code that I translated to C ran 300 times faster. What took hours in Matlab takes seconds in C. I tried that Matlab compiler, but never had much luck with it.


    Putting it all together, I usually write Perl scripts that run my C simulation programs many times; those programs dump out data arrays which I read into Matlab to visualize.

    There is a good reason for using "cat" in this way. If you are using "more" directly as you suggest, then if someone else logged in on the same machine uses the command "w" to see what everone else is doing, they will see that you are reading your mail spool file directly, and either (a) laugh at you for being such a unix geek, or (b) realize that you are someone they can ask all their dumb unix questions. On the other hand, if you are using "cat" as the previous poster suggested, anyone else doing "w" will simply see that you are running "more", but won't know what you are reading with "more".
