And hope that it's the right voltage!

And what if I don't have a battery in my computer?

I never installed the battery in my previous laptop, so I would need an outlet at all times. It didn't matter to me since it was so heavy that I couldn't use it except as a portable desktop anyway.

I suspect that mechanical hard disks stand out since they are lubricated with some kind of oil. But otherwise not.

In my home I have way too many hard drives laying around from old computers - and a lot of other electronic parts. It will take quite a while for them to go through the stuff - provided that they can find useful controller cards for reading them.

At least I interpreted it as humans being on the edge of becoming extinct.

But in reality that would take something more deadly than Ebola and as contagious as the common cold.

Looking at a larger perspective it do look like we are too many humans around on this planet and that a severe cut to 1% of the current pressure would probably be necessary to solve the problem of overpopulation and environmental impact.

Especially at people in politics...

And what is the limit you have to consider for job hopping?

Also consider that if a person has had different jobs in different areas of experience it can be an advantage - it also depends on why the person was holding on to a job for a certain period. It may have been a time-limited job. A year in heavy industry, a few years in commercial software development, a few years in government work - it can be an advantage.

That is when you are young, when you get older a lower frequency may actually be better.

Boeing still builds the 737...

Add to it the arcing that occurs from bad insulators on the grid - sometimes they cause a lot of RFI - and they are local. Just go out and listen to a high voltage power line when the weather is humid - there's usually a buzzing on the line caused by surface currents on the insulators.

The electric noise would only be useful for a very rough approximation of where someone is located and largely depend on interference on the grid. At best you may find the county or town where someone is located, but it won't necessarily be conclusive since it's important to also match that to the correct time slot.

The noise brought in as location information in CSI etc. is often depending on more distinct noises that are well-known. A subway station has one set of specific noises, a harbor has a different set. Sometimes among the general noises there are some distinct parts that can help pinpointing.

But if someone records the noises of an out of place location and then use that as a background then it will throw investigation off track. It's impossible to realize straight away that a certain noise is good or misleading unless a repetitive pattern is heard because the noise is looped.

There are no inventions in operating system UIs since the release of XP, right now we are suffering one big experiment that seems to be led by a horde of drunken chickens...

Brings up to me that I think that "First Contact" was the best movie among the Star Trek movies.

Doesn't help when they move around whenever you resize. They are never in the same place, and they never look the same which forces me to search for them every time. Sometimes only resort is to maximize the window on the largest screen I have to find what I'm after.
