  1. Re:reg stack? on Revolutionizing x86 CPU Performance · · Score: 2
    That sounds interesting. I really don't know much about chip design, but I wonder how efficient a CPU with several stacked registers could be, if the code was designed to work with that.

    To prevent stack overflows, a logic system could move the highest parts of the stack into cache (which gets moved to memory).

    I imagine registers are scarce because each added register increases other logic component complexity by an exponential amount, but if there were several stacks backing each register, you can't access the middle of the stack, so there would be no extra logic required.

    Anyway, I know absolutely nothing about this stuff, so I'm probably making quite an ass of myself, but I see there are quite a few knowledgeable people here on this topic, so I wonder if anyone could comment on how practical this is? =)

    Personally.... I'd go for a stack machine. Easily the most efficient compute engine.

    Don't forget to also do it in trinary (base-3) for that little extra kick =)

    Has anything new happed on the base-3 computing front in the past year?

    I think the argument was against PDAs in general, not this particular 2MB PDA. Get a Cliè and a memory stick, and then 2MB is insignificant, so long as the application supports VFS. If this particular application is as useful as described, any extra costs are certianly justified for that kind of convenience.

    BTW, I keep a local map of two surrounding counties, a dictionary, a complete calorie database, and several other very useful applications in my Cliè, and I still have 4MB free internal memory, and more than half of my 32MB memory stick memory free.

  11. Re:This is awesome! on VNC, No Longer Orphaned · · Score: 2
    This is a very good question.

    I actually just discovered VNC yesterday, after getting frustrated spending two months wasting my time with PCAnywhere.

    Then I spent most of friday playing around with VNC, and I was quite impressed. I was glad to get full color and about two times the speed of what I was getting in 4 colors on PCAnywhere.

    Then near the end of the day, I came across TightVNC. I tried it with maximum compression, and it flew! It was much faster than VNC, and an order of magnitude more useful than PCAnywhere.

    I almost stayed late playing with it.

    Sure there is nasty jpeg compression when I was really taxing it, but at least I could get my work done. I was impressed though at the compression; when I would drag a window across the screen, it only needed to update what was in the trail of where I was dragging it from. I guess this must be some kind of motion estimation like MPEG?

    I'm actually almost eager to get back into work on monday to mess around with it somemore (I've only one computer at home, and it would be pointless to loopback connect). =)

  12. Re:Time to buy some really good sunglasses on More on JSF Laser System · · Score: 2
    Very interesting point. What's to keep an enemy from using a reflective material, not much unlike that used in traffic signs, which somehow reflects *most* of the light directly back at the same angle it's coming from?

    How do these signs work anyway? I discovered this once when I was playing with a laser pointer and a stop sign in front of my house. It looked really bright from my perspective if I was the one aiming the pointer, but if someone else did it from another angle, it didn't look much different from shining it on a plain wall.

    With that kinda wattage, I'd image the reflective damage would do more damage than just blinding. You'll probably wind up with a quite crispy coating if you're in the path of any reflected shimmers =)

    Since we're talking about materials, I am curious, what material is used for the (new?) Violet/UV LEDs? These things are quite nifty, as they actually generate black light (making things flouresce).

    I don't have any idea where they came from all of the sudden, but why aren't these at least as newsworthy as the blue LEDs? They have a shorter wavelength, so they should be more useful in applications which demand a higher frequency...

  21. Re:Same story you read? on Slashback: Bugfixed, Attribution, Atkins · · Score: 2
    I'll second this. I combined a low-carb diet with the Hacker's Diet (to keep myself enteratined with the numbers), also keeping my calories under 1200/day. I lost 45 pounds in a little under two months.

    I started on this diet plan when I found out my triglycerides were over 1000. I went back to the doctor three weeks afterwards and my triglycerides were down to around 300.

    I have since raised my calories and increased my sugars and carbs a bit, and I have definitely seen a slowdown in my weight loss, but also an increase in my energy level. I thinhk I cut my calories too much in the beginning becuase all I wanted to do was sleep.

    Now I'm losing about 1-2 pounds per week just by keeping my carbs under about 100g/day, and my calories under 1,800.

    I don't imagine too many people can tell the long-term effects of anything until it's been tried for 75 years, but I think a low-carb diet is a good way to get started on losing weight, and getting educated about just how bad our food selection is.

    One good rule that I learned was to "shop the perimeter" when going to the grocery store. You can entirely skip the asiles in the middle, as they're mostly just filled with high profit, low quality carb-loaded junk.
