I suggest you look up how SDN switches and Juniper routers work. In neither case is the commodity OS used in the forwarding path; it is just a control-plane OS, and the performance of the control-plane OS's network stack has no bearing on traffic performance. Whether FreeBSD's network stack is "better" than Linux's is debatable (I thought all the BSD-heads "knew" that OpenBSD's network stack was the best, not FreeBSD), but it has no relevance here.

Being in somebody's attic is not impossible; they could have been mislabelled and targeted to be thrown out and somebody just kept them (possibly without knowing what they've got). I've got a Skylab Operations Handbook for the Apollo Telescope Mount sitting on my desk, and I know my father had reel-to-reel tapes of the audio from the lunar lander missions on the shelf at one point (both were being thrown away).

Stuff also gets actually thrown out eventually. I've seen many boxes of punch cards from NASA going to recycling.

Comment Re:I'm a big support of IPv6 but... (Score 1) 595

Hmm, I thought all of Comcast's US residential service supported IPv6 now. They do DHCPv6 prefix delegation, allowing requests up to a /60 by default (although calling their support number may not get the right answer). I've been using it for a couple of years now. Their business service is still rolling it out though, and (from what I understand) requires you to use their provided router instead of your own.

All measurements systems are arbitrary.

Yep. The conveniences of metric, such as scaling factor, are also arbitrary. Why should one cubic centimeter equal one milliliter? How is a centi-something equaling a milli-something "intuitive"?

For science (you monster!), it all goes into a computer anyway, and (learning from history) it should all have units specified. At that point, there's no functional difference between meters, feet, and furlongs.

Also, Celcius is a less-convenient scale for weather temperatures. Farenheight is a finer-grained scale (using whole numbers is more convenient) and has a range based on the "typical" temperatures experienced in most areas (obviously not the extremes).

I think the only improvement from using metric in every-day life would be in cooking, where it would be easier to convert units and modify recipes.

You obviously haven't ported OpenSSH to a different OS before. Even among Unix/POSIX-like OSes, there is significant variance between platforms that something like OpenSSH has to deal with. Go look at the diff between OpenBSD OpenSSH and portable OpenSSH (for all the other supported platforms).

Also, portable OpenSSH uses extended security features that tend to be platform-specific (but useful enough to make it worthwhile to use on each specific system). I expect that there is Windows security functionality that doesn't map onto the current OpenSSH setup (but is worth extending OpenSSH to use).

I really hope that Microsoft makes a native port of portable OpenSSH to Windows. Nothing against the Cygwin folks (the Cygwin OpenSSH is great), but a native port that is more integrated into the "Windows" way of doing things would be good.

Yep. My grandfather was an outlier - he lived IIRC about 8 years, and about 7 of that pretty good outside of chemo IIRC every 6 weeks. A former cow-orker was diagnosed and didn't make 6 months.

From what I understand, part of the problem with the common forms of pancreatic cancer is there aren't many symptoms until it spreads, and once it spreads, it is aggressive and kills rapidly.

I think Staples vs. Office Depot/Office Max retail locations is similar to Home Depot vs. Lowes. In some areas, one is better, while in others, a different one is better.

Where I live, Staples has multiple locations that are clean, organized, well-stocked, and always have customers. They have copy/printing services, UPS shipping, etc. There's only one Office Depot location, which is dirty, in a way oversized space (so when you walk in the front door, there's about 30 feet of empty space before you get to the registers and then merchandise), always disorganized and sold out of what you want. Individuals, teachers, small business people, etc. all go to Staples; the only reason to go to Office Depot is if you are in a hurry and you are by their store.

Comment Progressives have limited use (Score 2) 464

I'm lucky enough to still have great eyesight at age 42 (still use the good old-fashioned 6x13 aka "fixed" font in my xterms on my 108 dpi monitor).

However, my mother got progressives at one point, and wore them for a very short time before replacing them. She plays church organ, and has to be able to see music, keys, stops, and (optionally) the choir director. Different organs have different numbers of keyboards (called manuals), and with more manuals, the music stand just gets farther up and farther away. She has different pairs of glasses for 2, 3, or 4 manual organs. She tried progressives, but they were terribly distracting; she also tried traditional bifocals, but they didn't really work either.
