  1. Re:External Modems on Modem Success Stories With Linux? · · Score: 1

    Yeah, an external (not USB though) modem would work, or if you have an ISA bus, an ISA modem (ISA doesn't have the bandwidth to do software modems). Or just look for "Hayes Compatible" on the box.

  2. 2 dimensional matrix? on Multidimensional Crosswords? · · Score: 2, Informative

    Depending on which interpretation of dimensional you use, a matrix is either always 2 dimensional, or varying the dimension(s) isn't what you want. A tensor is the mathematical object that includes scalars, vectors, matrices, and beyond.

  3. Re:Single pixel gif? on Testing didtheyreadit.com's Mail-Tracking Claims · · Score: 2, Interesting

    Could be animated gifs sent slowly? I remember back in the days of netscape 3 iirc netscape had an aquarium webcam that worked by having an animated gif and new frames getting sent as they were generated. Or perhaps it was server push (multipart mime content). It was something like that which would work for this anyway. 1996 was a long time ago.

  4. Re:God no... on Tuning Linux VM swapping · · Score: 1

    sendfile is for stuff like webservers sending out content. These definately do want to cache, so I'm assuming sendfile will load stuff into cache too. Stuff gets faulted in and then sent directly however, without being transferred to userspace.

    There's no "copy file" system call, it's just a read and then write loop. However in many cases, the program doing the copying should use O_DIRECT or posix_fadvise DONTNEED.

  6. Re:It's the users' fault! on Secret Repairs Preceded TCP Flaw Release · · Score: 1

    TTL is (or should be) decremented for each second a packet spends in a router's queue or each hop. The TTL bounds the number of seconds a packet can live on the network, hence the name "Time To Live" instead of "Hops To Live".

  7. Re:How much visual difference will there be... on 600 PowerMacs Make One DVD · · Score: 1

    Yes, degradation is cumulative.

    10^16 kg/m^3. Damn html filtering.

    Probably? Neutron star density is in the 1016kg/m3 range. Though I don't think neutron stars come that small.
