  1. Agreed on Cassini visits Earth · · Score: 1

    Plutonium is one of the most deadly substances around. Having 75 pounds of plutonium ash in the atmosphere is not considered a good thing. Not to be alarmist or forget that we have several hunders atomic weapons pointed at the world, but it is a matter not to be taken lightly.

  3. Re:Light speed? on Scientists Find Evidence of Black Holes Sucking · · Score: 1

    I believe light speed is roughly 3x10^8 m/s or 186,000 miles per sec for you non-metric wanks. :)
    - Strangely enough that comes to 6.696 billion miles per hour. I suppose the light is trying to escape and is slowly being pulled in???

  5. I worked for a 25k user ISP and a 1.2mil one now on Ask Slashdot: Building a Large Email Service · · Score: 1

    Setup at the old ISP was this

    3 ultra 2's
    512MB RAM each
    30GB array by artecon that was NFS mounted.

    This was slightly overkill for us. A few this to keep in mind.

    1. Have more then on machine running this. I would say use 4 PII's. Use dns round robin for load balancing. If you have the money get a real load balancer. With an NFS disk array and sendmail file locking this isn't hard to administer.

    2. Use as much RAM as you can afford. 512MB min. 1GB to 2GB is better.

    3. Fast local disks. QPop servers files locally. Have at least 4 gig for mail to be queued. We had at least one user trying to cycle 2 gig attachments through our machines every month, Bastards.

    4. Set up qpop (or whatever) in server mode. This will decrease the traffic from you to your raid array. Server mode tels it that it is transfering data across the network, if nothing in the data changes just revert and don't move the extrea traffic.

    5. Disk. We were fine with 30, but upgraded to 50GB with the last upgrade. Artecon NFS mounted to the 3 machines. Look at Netapps though. You can cluster them in a failover config. I have heard of some hardware problems with them though. We pushed 16MB/sec across a peak so make sure you are AT LEAST ultra wide if not ultra2. You could set up a server with the disk attached and let it do your NFS instead of a full network disk thingy.

    6. I'd suggest sendmail, but qmail is nice, too. Sendmail seems easier to set up to use with pine if you want to hook a shell machine up to it with Pine or use a webmail package, but honestly I haven't played with Qmail much.

  6. Re:More efficient routing ( ever hear of a router on IANA Deploying IPv6 · · Score: 1

    I don't think this will make routers simpler. If anything they will become more advanced to keep up with the large amounts of routes and routers on the Internet.

    Take for example BGP on a core router. I would not run this on anything with less than 128 MB of RAM today if you want the full routes (I have 256 in my 7206VXR). Imagine once IPv6 starts taking off. I would personally say that routers will get more complicated so as to store routing data in smaller forms in an OSPF kind of way.

    Granted you can make a router pretty simple using IPv4 or 6, but if that all anyone ever needed Ascend would only seel their P50's which are about the min I would go with. Also as speeds increase so must the chips and software tricks.

  7. Re:Apache and IIS on Ballmer: Apache is simply better · · Score: 1

    Blah Blah Blah
    I have Apache doing the same with three Ultra 2's, which are actually a hell of lot cheaper then than the Quad x86 servers even including the load balancing system. Why you have the whole thing on FDDI is a mystery to me though.

  11. Audit trails - Questions on WSJ Says Linux Lags · · Score: 1

    Does NT actually do this? I think this is the crux of the issue. Linux can take critisism that other systems have journaling file systems. We don't like that we label as inferior to NT. Does NT logging actually allow you to see who edited files, who used programs, etc? I've never seen it under NT, but I'll admit I got my machine at working working reasonably well and tend to stay away from it's guts.

    Ha. Autobike. What a joke. Sure it's nice for Mom and Dad to ride around the block on nice level surface. Real biking requires sweet XTR Rapid Fire Shimanos with the handy thumb switches. Once you get off the road (or into the city) you'll be wishing for a little extra control.
