Statistically, that "cow" (ground beef) would be from ~200 cows. Sausage could be as few as one, but much more likely to be just as "processed" as the cow. Ham or Canadian Bacon might be from a single animal, but I seriously doubt Dominion's uses anything from the "quality" side of the market. The chicken is the only thing likely to have been from a single chicken -- unless they used "McNuggets", which is entirely possible. ("mechanically separated" is the term used.)

(There are some "how it's made" shows that shouldn't be watched.)

If this is like the upgrade I've seen, the ENTIRE STATION is down for the duration of the updates. The back office systems, credit card readers, EVERYTHING is down for updates and/or replacement. And the software is such a work of art, if any single piece doesn't work, you have to rollback the universe.

I have a friend who did this for a while (I still have the laptop with all the oddball software on it.) He's thinking he'd like to get a site done in one night instead of 2+. This is not something that is done like a 9-5 job. It's done more like midnight to 4-5am. And there's no wiggle room for screwing shit up: the station MUST open in the morning.

Fiber: 100km (~62mi) per hop, with a practically zero (femtosecond) latency optical regen, subject to physical breaks (idiot copper thieves, backhoes, trail derailments, etc.)
Microwave: 25mi per hop [limited by tower height and curvature of the Earth], with microsecond repeaters, subject to atmospheric disruption and misalignment

Last I read, microwave didn't do 100Gbps. Nor is it cheap to transmit many parallel streams. DWDM has been common in the optical space for decades.

You do realize a "mode conditioning cable" is for launching a single-mode laser into a multi-mode cable; that's a mixed-mode use, and only works because most SM optics (LX, ZX) have higher output power and much higher receive sensitivity. You're using optics rated to 10km (or more) and getting 1/16th that range out of them.

Standard "SX" hardware simply doesn't have the power or sensitivity to work over km distances.

And yet, the two existing fiber deployments in NC (Wilson and Salisbury) prove the exact opposite. And in fact, most "big business" have their ways around zoning, permitting, taxation, etc.

Those that fail do so for two reasons: 1) the incumbents drag them through enough legal bullshit they're out of money before they can buy any fiber, much less string any. 2) the all too common mismanagement found within any government project burns through mountains of cash, and then their business model is to burn even more. LUS and MI-Connection are good examples of #2 -- I don't know how much was spent building LUS or buying up the bankrupt Adelphia plant, but their plans for revenue were unrealistic. What I recall of UTOPIA puts them in both camps.

In that the only mailbox you have in your front yard is the one for the USPS, yes. However, there are private companies providing mailboxes -- 'tho they use the USPS instead of their own courier(s).

Given the cost of the non-USPS couriers (Fedex, etc.) and the fact the USPS loses money day after day, I don't see anyone stepping up to replace the USPS.

the FBI inspected the SEBs around the seat he occupied on his 4/15 Denver to Chicago leg

Did they seize the aircraft immediately after his flight? I doubt it. So a) the damage may have been pre-existing; they didn't look until after his flight. b) the damage could have happened well after his flight. And finally, c) NONE of this proves, in any way, WHO (or what) caused the damage.

It certainly is "still necessary". However, processors have gotten fast enough that people don't notice how horrible their OS and applications actually are. Compilers (read: gcc) have gotten *worse*, not better because there are so few people who really understand assembly, or the complexities of modern processors.

Actually, you can, but it's certainly a lot more work. But then, porting AN OS to a different processor usually involves more work than changing the -march option to gcc. (i.e. coding to handle a completely different platform. It's not like you can pop the i7 out of your desktop and replace it with an ARM or MIPS processor.)

Personally, I do something very similar... every address block assigned to APNIC. Yes, it's a shotgun approach, but it's surprisingly effective. HOWEVER, it's not something that can be done by everyone; it works for me because I have no need to talk to anything in Asia. That won't work for my employer as they have offices all over the world -- including Asia, and all of our manufacturing is done by companies in Asia.
