Understanding file directory structure isn't too hard but keeping it clean is a pain. As an example, say I need to convert a program from Hex to binary format. I know I could search the web for such a thing but I could also download some malware or even a virus. It is not a complicated operation, so I write one, tuned to the particular application I'm working on. In one case, a 16 byte HEX line is desired, as it is easier to examine and edit. In another case, 32 byte lines are preferred.
So, I write or modify another program I've written and place it in the current work directory. The problem now is that I have maybe 6 versions of the program. I dumbly use the same name for all of them. When I need one, I do a search and then have to look at each one to see if it is the one I'd like to use. About half are essentially the same but some have special features, like organizing sections into easily recognizable blocks based on the data.
What I'm saying is I'd like there to be a program to sort the programs out into some kind of order, even though, they may be in different directories. I don't like programs that have complex command line structures. I'd rather like to find a way to sort them out based on their purpose for being unique.
On to another subject, fixing your own car.
When disk breaks first became popular, places would charge more for replacing pads then shoes. It was a scam. Disk breaks are easier to work on, even the ones with mix parking brakes. Then most all shops want to turn the disk rotor. They rarely need this done. Even a badly grooved disk will function fine. The pads will quickly conform. If the disk has varied thickness around the disk, it needs to be turned.
Drum breaks are a pain. Fighting springs is a pain, even with the proper tools. Drums often do need to be turned or replaced.
Changing oil is a pain. One needs to deal with the oil removed in an environmentally correct way.
Even changing spark plugs has gotten to be a pain. A transverse mounted V6 will often need to intake manifold to be removed to get at the back set ( I got one of those ). I like watching the repair videos. I saw what one needed to go through to replace spark plugs on a Mercedes. It was the most ridiculous thing I've ever seen ( what a pile of junk, they call engineering ). While fixing ones own car is a good thing, it has more huddles today than ever before.
