 I'm going to start first, just to bring the ice. And the first two, I'm going to talk about is the amphetamine. So what is amphetamine? So amphetamine is, if you go to my doc, so I'm on a Mac. So what was the tools I'm going to be, I'm talking about for the back operating system. Some of them may be compatible with other operating systems and some of them may not be. But again, that's why we're here for you all. You can get an operating system with different tools and different things. I will let you hear it. So all right, going back to amphetamine, what amphetamine is, and this is right here on the doc, I'm going to click it. Nothing pops up that you can see, but it pops up on the menu bar. So what amphetamine does is it's great if you need to keep your computer on for longer durations of time. So if I click this, usually when you have a computer, you need it sitting out and you go get a cup of water or maybe you want to go somewhere real quick. Usually the screen say what comes on and eventually the computer goes black and then it goes into the power saving mode, right? So if your computer is plugged in, you may not need that or maybe you're downloading something and you really want that download to finish without the computer light just going off with you or maybe you have a presentation like this one and you can't afford the computer to go onto screen say the code. This is where amphetamine comes in. And then pretty much, you can set specific durations of how long you want the computer to stay on and it will ignore all your computer settings in terms of the screen saver option, the power off option and it'll keep it on for that destination outside. You can keep it on for five minutes to as long as to even hours. You can go on to a whole day if you want and you can even get even real granular and you can have it while a file is downloaded. You can say keep the computer on while a specific file is downloading to the computer. That way you don't have to worry about it turning off and the internet, you know, once the computer turns off use the internet connection that we downloaded especially to the deep file download while the app is running as well. So if you have an app running and you want to make sure as long as that app is running, I want my computer to stay on. This is a great app to make it happen. Again, very small app. It's in the menu bar. I clicked it and you didn't even notice it and very little wins too. So I click on it. It does, it makes it turn and let me know it's on and click right here and you can see it went to my default which you can change in your preferences but my report 25 minutes and now it starts to count down 25 minutes where my computer will stay on. And I can right click it again and turn it off or I can left click it to go into the options.
