Obsolete Advice (For things that still exist)

When Dad was teaching me to drive (1960) I downshifted our 1950 Ford and he said “Dammit, don’t do that! Brakes are cheaper than a clutch!”

My mother and grandmother were afraid of using a telephone during a thunderstorm. They still believed the same way about cordless phones.

We don’t have to change the blinker fluid anymore, do we?

Most of the information about battery charging cycles is based on specific battery chemistry, and shouldn’t be generalized to all rechargeable batteries or uses.

Yeah, that’s clearly wrong.

My wife thinks the car needs to have a “tune up” every now and then. I always explain there is nothing to tune anymore.

As to caches and removable media, there’s also the question of speed and scale. Modern USB is much much faster than original USB. OTOH, we’re all used to slinging much larger amounts of data around with impunity.

OSes have gotten more conservative about how much to cache as measured in seconds of write time precisely to lower the window of vulnerability to sudden disconnection.

If you drag an e.g 5GB folder onto your USB drive icon and unplug it 4 seconds later you’re screwed. Do the same with a 5MB folder and you can’t get your hand from the mouse to the cable connection fast enough to beat the computer having finished writing all of it.

So doing a proper eject (or at least waiting for the drive to indicate it’s idle) remains essential advice for corner cases that many of us will never experience. And hence is obsolete for most of us most of the time despite still being complete and correct.

Semi-true. Yes, the power off button is not physically interrupting the power to the computer; instead it’s sending a signal to the ACPI - Wikipedia firmware component to tell the OS power is about to be removed and the OS should perform an immediate orderly shutdown.

But the ACPI system doesn’t give the OS much time to respond. The OS can protect itself and flush cached data to your disk in time, but if you have a bunch of unsaved work in several open programs, each of which needs to prompt you to save it before being killed, well the electricity is going off before you see any of that. Which is part of the reason that many programs, notably MS Office, are now designed with continuous incremental automatic saving. So the amount of lost work in a disorderly shutdown from the app’s POV is seconds, not hours. For those apps that practice continuous incremental saving.

So yes, you can lose work, but no, you won’t end up with an unbootable drive or one that has lots of corrupted files on it.

Having survived a 9.3 earthquake of significant duration, I’d like to point out a couple of things here. I could no more have remained in a doorway than I could fly. In fact, the house literally spat me out the door onto the sidewalk. I’m quite certain that if I had tried to stay in that doorway, it would have beaten me senseless. Secondly, running out of a building in an earthquake is just foolishness. There are powerlines coming down, trees thrashing back and forth, shit flying off of roofs, and glass shattering. I saw parked cars lurching back and forth 3-4 feet. Thank you for your attention.

I’m confused. Isn’t an oil change what a lube job is?

I don’t think there’s any such thing as good advice for dealing with a 9.3 earthquake, beyond “don’t”.

In fact, I think that “a 9.3 earthquake” might be the wrong article. Shouldn’t that be “the”?

Nope.

A “lube job” is taking a grease gun and injecting fresh grease into the dozen-plus grease fittings that adorned a 1950s - 1980s suspension and steering system. And in really old (1930s - 1940s) cars, into the wheel bearings too.

A modern (post ~2000) car has zero of those fittings to grease.

Things checked in a tune-up:

  • Spark plug replacement
  • Air filter replacement
  • Visual inspection of belts and hoses
  • Fuel filter replacement
  • Inspection of fluid levels
  • Oil change
  • Tire rotation
  • Brake check
  • Car battery check

Your vehicle needs none of these done?

Sounds a lot like the Sumatra earthquake on december 26th 2004. Only Chile scored higher in 1960 (9.5 magnitude).

I still get tune ups just not as frequently as with my older cars.
I have a 2013 Impala.

There is a lot of “obsolete” advice in gym culture:

You need to workout 2 hours a day (now, the usual recommendation is to limit workouts to under an hour)

You need to workout every day (usually, ‘rest days’ are recommended, and sometimes even emphasized)

You need to be super strong to get big (now, lifting too heavy is called ‘ego lifting’ and ‘slow and controlled’ is the way to go)

Lift light weights with high reps for definition (leanness is a function of body fat, not higher repetitions)

Do shoulder presses (I.e. sitting and pressing a bar straight above your head, aka military presses) behind your neck (you never see those anymore)

Squats are bad for your knees (now, it’s tight hip flexors that are causing that pain)

Stretch before your workout (it actually weakens you)

Bounce when you stretch (now, it’s always smooth and controlled)

This extends to nutrition, too. For example, eggs (or egg yolks) were considered too high in cholesterol: now, they are promoted as a superfood. But people love to demonize fruit and vegetables.

Been through some earthquakes. The main hazard, if you are in your house, is that things may fall on you. Like a refrigerator, or a roof beam, or an unreinforced chimney. Crockery flies. I personally recommend throwing yourself under something like a heavy table.

Those poor fruits and vegetables, what did they do to deserve that?

The problem with fruits is that many are high in fructose, whi ch is bad for diabetics if the eat to many or mix them in ablender to remove the fiber. Most people don’t have this problem.

What?
