In any case, I hope I can get back to sleep tonight. I've avoided playing video games tonight to try to reset my system clock, but it's not that easy. It might be easier if I were not know in front of my computer. But it seems that once again, I'm seeing the Trump administration and its continued failures at being compassionate human beings. I suppose the latest problem is the administration trying to end DACA. I just don't see the point of punishing the children for the actions -- or crimes if you want -- of the parents. The children had no choice. It's like punishing humanity forever or at least for thousands because two people ate an apple they weren't supposed to. It's tempting to blame this on Mike Pence's influence, but I don't believe even Mike Pence is that terrible of a person. His boss, on the other hand, is definitely as bad as he seems to be.
I am getting back in the swing of things, but I have to admit I didn't do as well on a routers and switching test tonight as I would have liked. It's true I'm not interested in computer networking, but it does have some relevance for a server administrator. I think one of the classes should be replaced with C for people on the Linux path, since knowing more Cisco IOS commands isn't all that useful. (Not Apple iOS. They are completely different things. Cisco IOS came about first.) Laying cables will have to be a task left to someone else. I also dislike that these courses are only offered at night so I can't ride the city bus back home even if I wanted to.
Now, well, to the person worried that it's a video card problem on their Mac -- it's actually possible, but I wouldn't start with fixing that option. But if the air duster doesn't work, it'd probably be a good idea to take it to an Apple store. It could be a problem with the power supply or the cpu fan.
