For that matter, it doesn't even matter if it's a direct hit: Inductance is a bitch who will fry the strangest things, given an opportunity to do so.
That you seem to think that just because it doesn't stick up further than other protrusions makes any meaningful difference in the context of the reliable systems that are the entire purpose of TFS means that you don't fully understand the concept.
Over here in the real world, things aren't so cut-and-dry. Lightning is not a completely rational phenomenon, and one must take extraordinary means in order to reliably survive its appearance -- especially with outside antennas.
Meanwhile, please don't hang a GPS (or any other) antenna on any building in which I have gear that I am responsible for until you learn another thing or three: While I'd love to have a local stratum-1 timesource, I don't want your shit breaking mine.
How much beer, soda pop, kitty litter, dog food, and dinner are you willing to haul 10 blocks on foot?
Me, not so much (or at least, not enough). So, car it is. Or a velomobile, just maybe...
(I've been considering outfitting my bike to be able to carry more things effectively, but between the local stores' paranoia (OMG! He's shopping, and he has a backpack!) and the vandalism I've experienced with parked bicycles in the past, it's not looking promising. Nevermind the general hatred that drivers have toward cyclists here...)
I haven't used a UHaul truck with a governor in a coon's age; all of those that I've driven over the past decade or so were perfectly capable of going down the highway at any speed I dared to attempt.
Cellphone power is often dominated by processor and display power.
This is what you think.
But the fact that my smartphone gets very warm and the battery charge falls off precipitously when conducting a voice call (screen off, CPU more-or-less idle) says differently.
Further anecdotal evidence: I have an OG Droid which no longer has cell phone service. Its battery lasts for about a week in light usage (web browsing over Wifi, music player, that sort of stuff).
The exact same phone, with cell service, used to last about 24 hours, or about 1/7th as long, even if it were in my pocket and not actively used at all during that period.
So, clearly: There is something about these new-fangled phones that causes them to eat batteries at a rate that would make a DPC-550 blush, and it seems to be directly related to usage of the cellular radio.
In town, the average speed of my car tends to hover below 20MPH.
I don't think I want a velomobile for any sort of highway jaunt, but it might be handier than a car for getting to the store that's about 9 blocks from my house.
Three out of four houses I've lived in had brick chimneys, used variously for venting furnaces or water heaters or both. None of them had fireplaces.
There is generally a quiet and cool place at the bottom of such a chimney, often with a door allowing for cleanout. In my experience, dead birds tend to gather there.
That's not a stall. That's hydrolock, wherein one or more cylinders fill with water. Pistons are ruined, rods turn to mush, cranks bend, and blocks turn to scrap: It's fucked.
The difference between "stall" and "fucked" is the same as the difference between the nonchalant "Oh, I just rebooted it and it's been fine" and the much more serious "The fucker is seriously bricked" or "There were visible flames coming from that equipment."
My 1996 Firebird was exposed to a flood, with water more than half-way up the doors. The interior was a mess, and it was expensive to fix it (once to get it almost there, and again to make it actually right), but the rest of the car was fine.
Water didn't invade the engine or transmission at all: The oil, coolant, and fluid were clear. Water may have affected some bearings in some of the engine-powered accessories, wheels, differential, and driveshaft, but: I drove that car for nearly another half-decade before a deer did it in ("totaled" is a monetary construct), and it never experienced any issues before that.
I'm a picky bastard when it comes to such things. If the transmission shifts funny, or the engine is a little off, or the suspension seems wonky somehow, however slightly: I notice. This car was -fine-, indifferent from how it was before the flood.
Title issues? Meh: It was repaired by the insurance company, not totaled. There was no salvage involved.
Other than the engine and transmission, much of this stuff is exposed to water on a regular basis by simple driving through rain or snow...and while it'd all certainly be happier without that exposure, it really didn't seem to mind it a bit.
SOP on gasolineautomotive fuel pump replacements is, if possible, to do so with a full tank to minimize the risk of badness (gas itself doesn't burn, while gasoline vapors both burn and can be explosive).
What is it about a large volume of Diesel fuel that makes this different in any meaningful way?
If a liquid paraffin similar to medical grade mineral oil (but a lighter fraction) will keep a modern Diesel (yes, with a capital D) happy and survive long-term storage, then the problem is you: Go forth and sell.
If you care enough to put an antenna on the roof, then you should also care enough to pay attention to good grounding principals.
Grounded coaxial-fed antenna on roof == lightning rod. Period.
Without precaution and planning, the device responsible for dissipating that lighting (when, not if, it happens) will be your precious local Stratum-1 NTP source.
It's never hard to get grounding done right, but it's not always obvious, and it never happens by itself.
But if the protocol's time-dependency issues are fixed by an application, along with every other application/protocol's time-dependency issues, then fixing the protocol is superfluous because a functional system will already have a stable sense of what time it currently is courtesy of NTP. One cure for a thousand ailments.
Would you feel better about it if NTP were wholly integrated into the kernel? Why, or why not?
The version played on Weeds is significantly better* than the original recording of the same, which suffers from a whole lot of scratchy and not-so-good:
On Weeds, it sounds like something that was carefully recorded quite recently. The original...not so much, but it's a lovely song just the same.
I genuinely thought that the opening from Weeds was a modern recording until I went looking and found that it was relatively ancient, but just recently-polished. I imagine that lots of folks might be able to be similarly-confused just as easily as I was.
*: I say this with great reservation because I find that nearly all attempts at remastering old music are ripe with failure on many levels. But, IMHO, whoever did the work for this track knew what they were doing, and was allowed to spend the time to get it done well. I wish I knew who was responsible.
Don't bother trying to use a UPS with your generator. it won't work. Seriously, it won't.
Might work. Just might. It depends on the UPS.
We lost power for about a week this past June. I used my ~2kVA Tripp-Lite full-time inversion UPS to run any particularly fancy electronics, including the BFT and the stereo (and of course computers), mostly to isolate them from any funkiness with the generator.
It worked fine. No complaints from the UPS, at all.
Generator was a 5 or 6KW Troy Bilt thing, nothing fancy. I burned up a lot of gasoline that week, keeping the beer cold (ice was hard to find), reading Slashdot, running the dishwasher, sometimes a window air conditioner (or three), etc.
Again, no complaints. And if in doubt, test things first: You don't want to find that your well-laid plans just don't work.
I have been running several passive heatsink cooled servers for 5+ years on ambient temps that get as high as 85 F during the day while the AC is off and I'm at work. IMO, money is better spent on lower TDP components. Generally for server CPUs you have a choice of a lower TDP more $ cpu vs a higher TDP but cheaper CPU of similar power.
My own experience with mostly-passively-cooled modern PCs is that while temperatures within remain low enough that everything continues to work fine on a hot day (if I switch off the window AC when I'm out for the day, things can exceed 110F ambient inside), there are localized failures of capacitors.
Specifically, the hottest caps fail first. Cooler caps fail later, or not at all, or are shown to be visibly in a lesser state of failure.
The hot caps are right next to and/or above the passive heatsink. The cooler caps are a little farther away, and/or lower (in terms of gravity).
In many cases, these capacitors are identical and wired in parallel.
So, electrically, things are exactly the same. The only difference is temperature.
Just throwing that out there. (I try to keep cooling and airflow to a minimum to reduce noise.)
A horse-carriage is not the same as a modern automobile -- after all, it does not have a steering wheel or other amenities -- yet people always saw it as enough of a prior art to call it a car; short for horseless carriage.

No. I just work with antenna systems for a living. I have seen my share of gear that has been fried due to crude assumptions about lightning.
Please Motorola R56 a read before you accuse me of being paranoid.
It doesn't matter how far it sticks up.

It's no more wrong than the .38 that intersected the cat's head.

Average speed.
Top speed in my car, in town, with my driving, is ridiculously high. My average is far, far lower (red lights, turning, stop signs, etc).
We tried that and similar concoctions. They didn't work for our cat, which is now dead.
I had some 10base2 network cards. I threw them away a few years ago.
Please tell me that you don't also need a CGA card with a composite NTSC output, or a Hercules adapter, because I tossed those at the same time.
This is what you think.

You must live over there, then. Over here, diesel-engined consumer vehicles consist of the following:
- Giant redneck pickup trucks that seem to exist only to produce noise while blanketing entire city blocks in black smoke
- The occasional TDI Jetta or Golf
- Tired, old Mercedes diesels.
That is all.
Works fine on my rooted Droid 4 with a custom ROM.
Dunno WTF it's useful for, yet (if anything) but it doesn't complain about anything.
"Most people" (as I said) don't have an easy way to get rid of old diesel.
None of my cars are diesel. Most other folks' cars in the US are also not diesel. And TFA is about the US.
Diesel also goes bad in storage, and old diesel is harder for most people to get rid of than gasoline.
