    Rounding is not a privilege you can just apply at will. If you've studied engineering or physics (chemistry?) you know you that the amount of rounding you have to apply is precisely dictated by the precision of your input values and the calculations done on those numbers. Either rounding too much or too adds unnecessary inaccuracy.

    If you've had 10 hours of downtime, you'd know it sufficiently exact to have less than 0.5 hour error, but let's assume 9.5...10.5 hours -> 99.880%...99.892. Less than three nines even in the extremes of your measurement error.

    That guy is just another BSD evangelist. The short summary of his long story is "BSD is from a better breed created by superior software designers". I quote, he says Linux is "beat up, punched around, tweaked, poked, prodded, manged, digested, spit out, stomped on, chewed up, tossed out, brought in, and otherwise manipulated", and in the description of what BSD is, it comes down to "BSD is pedigree".

    He says SCO owns the Unix code, which is wrong. The Open Group's website says SCO bought it from Novell and this guy is happy to repeat that, but Novell itself says it didn't transfer nor sell the copyright of its Unix code to SCO. Novell sold the UnixWare business to SCO, not the copyrights (==ownership) of the code. From http://www.opensource.org/sco-vs-ibm.html : "On 28 May 2003 Novell stated[40] that SCO owns neither the patents nor the copyrights to the Unix source code." See also http://www.pcworld.com/news/article/0,aid,110904,0 0.asp

    He repeats a mantra that says "BSD is what you get when a bunch of Unix hackers sit down to try to port a Unix system to the PC. Linux is what you get when a bunch of PC hackers sit down and try to write a Unix system for the PC.". Note the consistent 'PC' as the target for the OS... With Linux supporting many more non-PC platforms than the BSD's, that statement is too wrong in its core to even begin talk about the details.

    What I don't get is how the BSD people keep feeling so superior when there is so much that Linux has and can do that BSD doesn't have or can't do. All the while they often claim to know Linux better than Linux people know BSD. I guess they simply enjoy bathing in their ignorance.

    The problems is that it's uncertain that every mention of 'millisecond' was meant to be 'microsecond'.

    For example, I can agree with "When you get into application-layer clustering, milliseconds of latency can have an impact on performance,'"

    But s/milliseconds/microseconds in that, and you're talking about a significantly reduced number of applications that need that kind of response times.

    Microseconds are short for most processes. For example, Linux task-switches 100, 250 or 1000 times, depending on the processor. That means the timeslices are 1us, 4us, or 10us. Applications already sit still, not doing anything for multiples of the timeslices, so latency in the same order of magnitude often won't be noticed much if at all.

    Not exactly. It's close, but it's not lossless. The reason for this is that the DCT is not fully reversible, and even if it were, the JPEG standard does not have a precision standard for the DCT/IDCT in encoders/decoders (not even IEEE-1180 like MPEG1/MPEG2), which means that there can be quite large differences between different encoders/decoders.
