This is not true at all. You're right that planes aren't like cars, but airlines absolutely do their own maintenance. The maintenance program is initially provided by Boeing and modified by the airline based on statistical monitoring of issues.

Inspection intervals are based on expectation of damage over time, not to verify if the installation procedure was properly followed.

Design requirements for airplane parts that experience rotation or are part of control systems are regulated to have locking features to prevent loose bolts from happening. If the initial installation was done improperly it could be a failure in quality control at Boeing. Or if they were installed properly but weren't designed with sufficient locking mechanisms it may be an improper design. Either way this could turn into an Airworthiness Directive which is when the FAA steps in to ensure safety.

Everyone should learn the basics of troubleshooting!

When trying to resolve a problem it's really important to keep as many variables under control as possible so that you can find the root cause and fix it.

I see lots of people who try a bunch of things without isolating the issue first but can't figure out what is wrong. Then because they messed with it so much it's almost impossible to figure out.

This is important for car maintenance, home maintenance, electronics, computers. Just about everything that can break or stop working right in your life.

It is undefined because the inverse of division is multiplication. If you multiply by zero, every answer is zero. If you try to invert that operation you can't know which number was multiplied by zero to get zero because multiplying by zero doesn't produce a unique answer for each operation.

Additionally, if you take the limit of 1/x as x approaches zero from the positive side the result approaches positive infinity. If you take the limit from the negative side it approaches negative infinity.

An interesting thing to think about is whether multiplication by zero really makes much sense in the concrete world. You can't really have zero groups of something or some number of groups of zero. Zero groups of anything is still nothing. We can think of that abstractly once we have the abstract concept of numbers, but in the real world that idea is nonsense.

I've found my ADHD is more difficult to deal with later in life. It is not because my symptoms are worse, it's more because my responsibilities have grown. More and more of my goals are longer term issues that require constant attention over long periods of time and following through with plans in a timely manner.

I also feel that medication has exacerbated my hyperfocus on things unrelated to my true goals. I get by just dealing with the high stress times that occur when things have been procrastinated long enough to become urgent.

Toothpaste. Generics are awful.

For me Tunic perfectly captured that sense of wider and magic that I felt as a kid experiencing adventure games for the first time. Hyper Light Drifter and Outer Wilds gave me a bit of that as well. I highly recommend all three if you are looking for a similar experience.

I actually have ADHD and the opposite is true for me. Working from home I can concentrate without distractions of office workers walking by, or talking about something that I'm not interested in but can't block out. I work in my office at home with the door closed for practically the whole day and it's great. My work has it's own built in structure, but I imagine that other kinds of less structured work could be very difficult for someone with ADHD.

The program was called "Power Peg" for those googling for it. It was a test program not intended to be used on the live market.

The Power Peg program was designed to buy a stock at its ask price, and then immediately sell it again at the bid price, losing the value of the spread.

The red shirt part of the joke is referring to TOS exclusively because it was so prevalent. But really it's a larger trope found across lots of different shows and genres. They may not wear red shirts but you'll know them when you see them.

I think it's a great joke and has stood the test of time. You should try watching TOS before proclaiming that the joke doesn't work.

Without reading the whole patent it did sound a bit too generic and obvious for the patent to be valid, but I'm not a patent lawyer. The comments from Touchstream were pretty great though.

I wouldn't blame a small company for not being able to bring a competing product to market against Google, but it seems like a long time to wait to sue someone making money off a stolen patent.

It's not misleading it's just written in a passive voice.

If you read the whole sentence it's fairly clear that BlackCat is the subject that is doing the claiming. There's room for making it more clear but it's not misleading as written.
