Here is a nice guide on the basics of ARMA 3.

I just want to add that extreme heat can slow down and crash the computer as seen in a video we might have seen before.

There might not be a noticeable difference, or we don't care, when it's just clogged up vents.  But I have seen much worse at my job. I have seen dust and smoke turn into something like cake. Urgh! Such a thing will surely destroy components faster than normal. But some say, at that time it would be time to upgrade anyway. :P



And I couldn't find much about it, just this interesting bit:


"Best Answer:  DC (direct current) only flows in one direction. AC (alternating current) is current which changes direction back and forth with a regular period.
The electrons really do flow. If you look at the "drift", or physical motion of an individual electron, it is much slower than you might think. In a 12-gauge copper wire carrying 20 Amps of current, the average speed of an electron is quite slow; about 1/250 of a mile per hour. There's just so many electrons moving along so slowly that it adds up to a substantial current.
Why then, when you flip a switch, does the light turn on so quickly? That's due to wave propagation, which is much faster. Think of waves in the deep ocean; the waves can move quite quickly, but if you're swimming in it, you're not moving nearly so quickly. You feel a slight up and down motion, but the wave may be propagating at 30 MPH. The water itself is not flowing along across the surface at 30 MPH, but the wave is.
It is exactly the same with electrons. While the wave is moving very quickly, the electrons themselves move very little. In the wiring of your house carrying 20 Amps of AC current, the electrons are wiggling back and forth 60 times per second over a distance of about one thousandth of an inch.
However, the wave moves much much faster, when you flip the switch, the change in voltage travels along the wiring at very near the speed of light (it's slowed down about 30% below the speed of light by the plastic insulation on the wire).
With that prelude, to answer your questions:
- the copper wire is not typically called an ion. During current flow, an atom may hand its extra electron to the next copper atom, but it also gets an electron from the atom on the other side. Thus, each atom always stays about neutral in charge. This is described as the copper atoms forming a lattice through which the "sea" of electrons can freely flow.
- a heater does not work by converting kinetic energy of electrons to heat quite the way you describe. Instead, it uses the electrical energy available on the conductors of the power cord, which takes the form of electrostatic force of attraction which pushes electrons from the negative line to the positive line. As an electron eneters the heating element from the negative line, it feels a strong force of attraction towards the other end of the heating element, which is connected to the positive line. The electron accelerates due to this force, and speeds up somewhat, but it travels only a fraction of a millimeter before it collides with a microscopic defect in the lattice of the heating element, and decelerates and transfers its kinetic energy into vibration of the lattice of atoms of the heating element (i.e. into heat). It then accelerates again, then hits another defect.
The main thing which distinguishes the metal of the heating element from the metal of the copper wires feeding them is that the heating element has a higher density of lattice defects (i.e. higher resistance). An excellent analogy is American falls at Niagra, where the water approaches in a deep, broad stream moving relatively slowly at high potential (i.e. the negative copper wire), then tumbles down quickly under acceleration of gravity, losing potential, but hitting a bunch of rocks on the way down. Hitting each rock slows the water down, and also transfers some heat to the rock, but after each impact the water accelerates again as it falls to the next rock. Then, the water leaves at lower potential in another slow, deep stream (i.e. the positive copper wire)."



Well all I know is to keep things clean 'n cool!

Here's another thing that's cool. https://youtu.be/zPqEEZa2Gis

I never meant dust.. Like Jake said, you just wanna be right by saying I'm wrong, but I'm right, right?... Plus that sentence was really hard to read man.. Can I get an second opinion on this? :P

Yeah heat makes the electron move slower right? Like it's getting more resistance.

sure.. you want her candy.. sure  :P


Awww ok Jake, let's not swap, lemme just send you some shit. Maybe I could pull it off if i cram it up inside a peanutbutter jar.. or something.. Or I ship it to a state where it's legal then ship it from there to you. ^^

You know, it's still hard to see if there are new posts posted here. The grey or the white is hardly visible, and have to hover the mouse over it, to see pop up text saying New or Not New Posts.


Anyway, YES! Sure, I'll have a go at the new stuff. Which are.... what?

Software and Operating Systems / Re: Upgrading to Windows 10
« on: September 09, 2015, 07:43:53 PM »
I work in a repair shop. And I already hear all these nasty NASTY things man!

One lady brought her laptop, upgraded to win10. Her work involves a lot of writing. And she has a lot of files, that she maintains.

After the upgrade, she lost Admin rights to everything. She lost the ability to download and install things.
All the files she works with and probably other file types as well, were altered in such a way, that you could not edit your files anymore. All the files became write-protected.
We thought we had fixed the problem by making a new admin account, and then changing the original one again. And manually removing the write-protect, folder by folder. But that failed now, as she has returned with the laptop.
Text files are behaving so weird, one half portion was editable, and the other half of the text was write-protected.

We are hoping that going back to win7 will fix everything again.



Other stories I heard were; people's screen not working anymore, video card not working anymore, network adapter non functional.

So even though you could upgrade your pc to win10, it doesn't mean it could become a good thing.
Some hardware will just not work, if it's too old, or from some weird brand.. who knows.
And you only have 1 month to go back to win7, after that I guess it means... a full format.



I wish this was disc based,.. not an upgrade.

Hey Feb, I like the way you are approaching this. First the right charisma, and then variants of that.


Not to keen with the first one, and I think Paki meant that instead of "second", as he mentioned it twice.


I must say I like the second one the most, and the third. But maybe without the dogtag.
The last one (current one) is not bad. I don't like the colours there though. And the "r"'s in recruit were a bit hard to make out at first.


And the fourth one, well .. it's not bad but not great either. The main font could use some work ( damage, shattering, bullet hole)
