Do I still need to stock a crossover (Ethernet) cable anymor

[Jonas Schneider]

Today I tried to hook up a Rocket M2 as a super powerful (miles) Wi-Fi
extension for my home router, when the POE light went out whenever I
plugged in the power cable. Huh?

Turns out it's a crossover cable, mixed up with the bunch of my other spare
Ethernet cables.

Do we even need crossover cables anymore?
Or did they go the way of 8-track players?

You HAVE one, which is apparently more than you currently require.
What you want now, is a non-removable label that identifies it as a crossover
cable.

There's a fair amount of older hardware that's still useful, and that cable
confers a kind of compatibility you will certainly need, soon after you discard it.

Most devices do not need cross over cables anymore, but there may still
be the odd one floating around out there.

Technically only* gigabit devices are required to support auto MDI/MDI-X
switching, but in practice most 10/100 devices have also supported it
for many years.

[*] not sure about 10Gbe and faster, I've only used it over fibre, and
with a switch between devices, but I would expect it to be auto over
copper too.

You're never gonna need one...until about a week after you
dispose of it.
Better to have and not need than to need and not have.

That is the way it is for everything. I worked at a plant that was
built about 1965. At that time there was a spare part that looked like
a big auger. It was about 10 feet long and a foot in diameter. It laid
around in the way up to about 2005. We got a new plant manager that had
us get rid of all things we had not had to replace in the last 5 years.
Out went the auger. Wouldn't you know it , a month later it was needed
to replace a bad one. Same as with another piece of equipment . I
forgot what it was, something like a 20 HP motor and gear box. It was
sold as scrap. Before it left the plant site it was needed and we had
to buy it back for a lot more than it was sold for.

I have not seen it, but heard that some new cars do not even have a
spare tire now,but come with a can of Fix a Flat. Might be fine for a
nail hole, but if there is a large cut in the tire,itwill be useless.

With spares, if it has NOT been needed in over 5 years is the time
to KEEP it, not throw it, unless the machine the spare is for is no
longer in use.

Yes. I had to buy a real spare wheel for my car because it didn't come
with one. I take it with me on long journeys and have needed it several
times. Around town, I leave the wheel at home because a friend can bring
it to me if required. It is a nuisance that there is no storage space
for the wheel other than the luggage space. There seems to be a well for
a "space saver" wheel, that they used for storing the bottle of goop and
air compressor, but I bought a real full-size wheel so that won't fit.

I've read that the goop that they supply instead of a spare wheel will
ruin the tyre every time, and that seemed an unacceptable waste to me.
Also as you point out, the goop won't fix a really big hole.

I hated it when they went to the small tire. If you are very far away
from home you either have to poke along or find a place that is open to
fix or replace the flat tire.

Some cases not too big of a deal unless it is at night or maybe a
weekend. If like the tires I bought I have a guarntee with them, but
have to go to the chain store I bought them from. There may not be one
for many miles and if out of town hard to find one.

I did see a small car driving around town and I am sure they had 4 of
the 'small spaires' on it.

I've advised friends to carry an inner tube and various tools of the
tire trade if they don't have a real spare tire.
<https://www.amazon.com/Slime-5001-Auto-Inner-Tube/dp/B000ET8CZM>

When I was doing service calls in the middle of nowhere, I rescued
various 4-wheelers from a long walk by installing an inner tube, and
inflating it with a battery operated compressor.

The key tool is a bead breaker. I used two crow bars, which required
2 people to work effectively. This would probably have been better:
<https://www.eppys.com/37--Classic-Style-Tubeless-Tire-Iron>
or one of these:
<https://www.bestbuyautoequipment.com/bead-breaking-tire-hammers-s/1144.htm>

I also carried, baby powder, air compressor, valves, valve tools,
valve covers, double ended tire hose, patches, extra rubber cement,
plug kit, etc. If you've replaced the inner tube on a bicycle or
motorcycle, without removing the tire from the rim, you know how it's
done on an automobile tire. Incidentally, the small battery operated
tire inflator compressors take only a little less than forever to
inflate a tire.

Oddly, I've only used the plug kit on my various vehicles after
driving over a nail or screw. However, the other stuff is useful for
fixing other people's tires. My palatial office is close to where a
major highway dumps into town. I'm forever plagued by visitors
dropping in after the eventing commute with variations on a tire
puncture. They would then ask to "borrow" the tire kit, which usually
means me doing the work and dragging the shop air compressor into the
parking lot. Fortunately, such irritations have ceased in the last
few years, when I've made it a point of going home at a more
reasonable hour.

It won't fix a cracked valve stem either -

It's a real bugger if you blow a rear tire on a RWD vehicle with
Limited Slip too. You have to take off a front tire and put the spare
on there, then take off the flat rear and replace with the front - and
from the same side if you have directional tires.
Can't carry a "matching" tire for a spare that way either and leave it
on....Which is part of the reason they went the "no spare" route.

I know guys who's cars have sat at the dealers or the tire shop for a
WEEK waiting for the right tire to be couriered in from Kentucky or
Florida to Ontario because there was none closer (one was a Mercedes)
