Or side-and-rear-mounted lights that illuminate the road beside you, and a V2V communication bus that allows headight systems to cooperate to light the road and not shine in other driver's eyes.

I actually find this research more realistic and practical than self-driving cars.

When people can't see well they feel they're in more danger so they drive slower.

Yep, and start aiming their rearview mirrors to shine back in the asshole's face.

No honestly, why these boneheads can muster the balls to tailgate me and turn on their highbeams, but don't have the balls to cross the double line and pass me is a total mystery. I suspect they are just satisfying some repressed passive-aggressive pathology. Because I sure as hell am not going to speed up no matter how much of an idiot they make of themselves.

Sales of Pepsi on my part rose when the regional Coke distributor stopped shipping Splenda Coke to what seems like all of New England.

I don't buy too much into "aspartame bad, mkay" (though I suspect it may be more likely to cause me headaches, anecdotally, but then my initial trials of Zevia were not promising on that front.. more data needed there) but Splenda tastes MUCH better once your taste buds adapt to it, and even though I prefer Coke over Pepsi I made the switch because compared to Diet Coke, even store-brand splenda sweetened soda tasted better. I still drink regular diet coke in restaurants or when the grocery store (frequently) runs of of alternates.

Sales of Pepsi on my part fell to 0 when, last year, the regional Pepsi Distributor decided all of New England had to go without Pepsi One.

Sales of Price Chopper store brand are up, up, up, at least where I shop. Yes I went there. Was forced to really.

Meanwhile I watch cases of vanilla-vita-lemon-yuk variants of these colas sit on the shelves untouched and wonder why distributors think nobody was buying the Splenda. Maybe they got their bar codes mixed up.

It is not silly at all to order that. A double big mac combo with a diet soda is 1260 calories. With a sugared coke it is 1580. At a calorie budget of 2000-2600 calories per day for a sedantary male, saving that 320 calories is the difference between being able to eat 760-1320 calories at other meals, or having to scrimp by on 440-1000 for the entire rest of the day.

Not to mention the coke has a high glycemic index. The fries and white bread may be partially balanced by the meat, but add sugar and that balance is going to get way out of whack.

Skip the CCNA and just read some topical books. I've been working networks my entire career and every time I crack a CCNA book, I get 2 chapters in and decide to go read something that is actually useful instead. Most of the things CIsco seems to think every network admin needs to know are job-specific skillsets you'll probably never use and can be picked up when and if they are needed as long as you've put in your time. Or whatever flavor of the month monstrosity they are pushing on their customer base as a "must have" just because they are the only ones who have it (though they seem to have stuck with IP SLAs longer than a month.)

CCNA is basically a prerequisite for SE training, not really worth the time of anyone who doesn't have to answer questions all day from sundry customers. Also required for nwteork admins who for job-market reasons need to stoop to working for PHBs, but IMO you're better off working for an employer who waives that requirement when they see your years worked.

Certainly CCNA is not the best thig for SAs in particular. Learn in this order: ARP, IP subnets, iptables, rudimentary tcpdump/tshark and VLANs, and you'll be more than capable of escalating tickets to networking competently.

You're not just reducing entropy when you do that. When you iteratively feed back the same hash over and over you increase the odds that you'll fall into an internal cycle in the hash, and the number of inputs in the cycle can be much much rarer than the number of inputs in the path to the cycle. Though more modern hash functions tend to be designed to reduce the impact of that.

Usually to figure out all the little jobs the guy was doing that everyone else wasn't even aware had to be done, and B2B contact points. Debriefings are only partially effective.

Anyway as to the OP, block access to freecycle now so he can't give away his couch. Then you can have it.

Every 'if' statements creates a discontinuity in a function, ask a mathematician why discontinues functions are ugly.

Not every "if" statemet does this; it depends on what is inside the if statement. Often they are semantically equivalent to plain old bitops math.

Also, CPUs are rather good at handling conditionals, in fact are designed these days to handle them extremely well, and conditionals are very often what we need computers to actually do to get work done. If FP was a viable approach to real world problems, then successful FP platforms would not be so riddled with cheats and workarounds.

Mathematicians should be consulted to solve complex data dependency problems in isolated subroutines. Listening to what they have to say about the macro matters when it comes to programming leads to doing some really stupid stuff and obsessive golden hammer swinging. This is because problems in the real world (and especially in real time) are arbitrarily complex (and corresponding solutions are approximate) and not amenable to the clean set of prerequisites necessary to "solve" them using mathematical techniques.
