It's actually a bit tricky to calculate what you want.

In Linux, the same memory can be both cached files and memory in use by programs.

Memory in use by programs can be dropped from RAM if it isn't actively used, the same way as cached files are dropped from RAM.

So just adding up the total amount of memory mapped into programs doesn't give a good measure of how much RAM is actually being used by those programs.

What's more, a lot of the memory used in that way is shared among many programs. Calculating the contribution of a single program, in terms of how much memory would be freed if you killed that one but kept everything else running, is tricky. And even if you calculated that exactly, it's not necessary meaningful.

If you think that's unnecessarily complicated... well, it uses much less RAM that way than doing it the simple way :-)

Anyone else running into this? I'm still getting used to the resistive screen (coming from "that other phone").

Yes, I see that every now and then. Icon and sound indicate a click, but app doesn't start (in my experience, this only ever happened on the desktop, never saw it inside an app itself). Slight nuisance. Will check bugzilla about this.

Or maybe you have a bad unit because none of the folks with the pre-release units ever mentioned stability issues...

Jesus Christ again with the Eldar love. You even created a thread to highlight issues - how many responses you got to that?

Are you Eldar?

Did you have to blaspheme ? Very offended by your disregard for my faith.

Here we go again with the overly sensitive people....somebody get some cotton balls to shield this guy.

I got a decent one:
A Greek priest is driving down to New York to see a show, and he's stopped in Connecticut for speeding.

The state trooper smells alcohol on his breath, sees an empty wine bottle on the floor, and asks,

"Sir, have you been drinking?"

The minister replies, "Just water."

The trooper asks, "Then, why do I smell wine?"

The minister looks down at the bottle and exclaims, "Good Lord, He's done it again!"

What's up with " internet2.voicestream.com" someone mentioned this earlier, and I'm just wondering why I should change my settings to the internet2 instead of just keeping it on the internet[1]

As I understand it - one is the WAP network and two is the normal data network.

Least thats how it used to be back in the day.

Of course, but if that's what you want to look at then you're already getting into more detail than you usually need. He didn't ask about calculating for an individual program, he asked about the system. `Free` (non-busybox) simply tells you how much swap you're using and whether you're cache starved in just a couple lines per box. It's nowhere near adequate for *tuning* apps or systems. However, the free RAM, buffers/cache, and swap used are 3 basic and very useful "RAM health" metrics for the system.
