  1. Re:FreeBSD on OpenBSD 3.2 Available · · Score: 2

    I've always been a fan of FreeBSD. How does OpenBSD compare?

    The install is a very straight forward, no nonsense bare bones affair. My installs typically take on the order of 3 (THREE) minutes.

    The file system, config files and man pages are very clean. The resulting install is very tidy and pretty small. From there you add packages to taste.

    Forgot to mention. My favorite method is to copy my OpenBSD downloads to my iBook, served as http with Apache when required I do local network installs where ever I need to take it.

    Network installs are really nice, and doing it with just a floppy over a fast internet connection is excellent too.

    I love OpenBSD. It's so clean it's clinical. The only time my OpenBSD machines have down time is when I'm upgrading them to the latest releases or patches.

    Yes i realize you can isntall over the wire and then create an image, but not when you are on a slow link.

    Actually, I just finished downloading OpenBSD 3.2 for i386. It stopped while I was sleeping so it could have come faster if my 56k ISP didn't have a time limit for dial-up connections.

    Just grab the i386 directory with "wget -cr ftp-or-http...", burn it to /3.2/i386/ as a bootable CD using cdrom32.fs as the boot image.

    You now have an i386 bootable OpenBSD 3.2 CD with just a 121MB download. If you don't want a GUI, you could omit the downloading of anything that starts with x to make it an even smaller download (67MB).

    You could download the system and kernel sources, ports and packages if you want too...

    I just did it over 56k no problem. I still like to buy OpenBSD CD's though. Now I'm off to get macppc and mac68k (my CD will also be macppc bootable)...

    all your explanations of how pool balls move about a pool table are really basic physics.

    Yes I know.

    Rather than accusing the smart table of failing

    I didn't accuse the smart table of anything. I'm just stating for anyone that might think that "angle of incidence = angle of reflection" is too simplistic for pool physics.

    (getting the player to properly execute the shot, however, is another story).

    Jeeze you think so Einstein? Humans are usually the weakest link in automated systems.

    I don't think anyone would invest as much time as they likely did in creating a 'smart table' without realizing the balls have spin. I would guess their understanding of it all goes far deeper than your own.

    I suppose you think that you are insulting me? First of all, there's no need to get defensive, I'm not attacking them. Second, I would bloody well hope that someone who sets out to make a "smart pool table" (whether as a non-technical visionary with money or a geek studying the physics) would know more about it than me, who hasn't studied it beyond mere curiosity.

    but the cool this is that the display actually works like RAM (it retains its state until voltage is applied to reset it)

    Cool, some people will get to watch their BSOD's a few seconds more.

    On a serious note, I wonder if this could actually cause video card makers to make cards that use memory that does not have to be dynamically refreshed, since the monitor pixels can hold the image. Might reduce memory latency for the frame buffers of the future.

  6. Re:smart pool table on Smart Pool Table · · Score: 4, Informative

    All this "laser" business reminds me of an old episode of Quantum Leap.

    Lasers are actually not practical for showing pool ball angles after the first bounce (even if the shooter takes imparted cushion spin into account with off centre shooting) due to the fact that the angle reduces after each successive bounce due to spin the cushions impart on the ball.

    If you hit a ball hard at a moderate angle, intending to get the ball to bounce back and forth many times between two cushions, you will find that the angle will keep getting closer to 90 degrees to the cushions, until it actually appears that the ball is just bouncing back and forth parallel to the cushions 90 degrees to those being bounced off. Going from a moderate start angle to close to 90 degrees quite quickly.

    I don't think photons suffer the imparted effects of cushion spin.

    Also, not related to angle, but velocity, is that when a ball is first hit (on centre) it moves across the table surface initially without forward "rolling" spinning. The friction between the ball and table surface actually slows the ball down mostly up to the point where the rolling becomes "in step" with the velocity. When this ball hits a cushion, this rolling speed is slowed dramatically by the sudden braking effect of the ball pushing hard into the cushion and any rolling that remains after the bounce is quickly reversed as the ball now starts rolling in the opposite directing, again due to the friction of the ball against table surface. This in addition to energy being absorbed by the cushion (well, I don't like the term "absorbed" being used to describe energy "loss". The energy is converted to sound and heat) has the overall effect of making a ball travel much less than if it were to be hit with the same force without obstacles.

    All I'm saying is that if people are hell-bent on running SCSI for some reason, they're more than welcome to.

    SCSI has the ability to queue commands and re-order the pending commands in such a way as to reduce head movement. They can also read and write to the SCSI bus while they are carrying out received commands and share the SCSI bus bandwidth with more SCSI devices on the same bus.

    An IDE bus can only service one command and one device at a time.

    If a SCSI drive was working on one command fetching data and another four commands were pending: 1st near the start of the disk, 2nd near the end, 3rd near the start and 4th near the end, instead of the head movement going, start-end-start-end in the order that the commands were received by the drive, the drive could re-order the commands while it waits for the current command to complete so that the commands would be carried out: 1st, 3rd, 2nd then 4th so the head movement would go: start-start-end-end, reducing time to fetch the data due to reduced head movement. 1 full stroke versus 3.

    For desktop apps, this doesn't matter so much. But for database servers which can tend to send lots of small requests scattered randomly around the disk, this can have a huge performance gain over IDE drives, many many times.

    Perhaps Apple can remedy this a little with many drives. Maybe they can perform the re-ordering in their SCSI interface?.
