1. **Print your name and your best friend's name** using Println twice. [Check out this exercise here](https://github.com/inancgumus/learngo/tree/master/02-write-your-first-program/exercises/01-print-names).
2. **Say hello to yourself.**
1. Build your program using `go build`
2. **Send it to your friend**
S/he should use be using the same operating system.
For example, if you're using Windows, then hers/his should be Windows as well.
3. **Send your program to a friend with a different operating system**
So, you should compile your program for her operating system.
**Create an OSX executable:**
`GOOS=darwin GOARCH=386 go build`
**Create a Windows executable:**
`GOOS=windows GOARCH=386 go build`
**Create a Linux executable:**
`GOOS=linux GOARCH=arm GOARM=7 go build`
**You can find the full list in here:**
https://golang.org/doc/install/source#environment
**NOTE:** If you're using the command prompt or the PowerShell, you may need to use it like this:
`cmd /c "set GOOS=darwin GOARCH=386 && go build"`
3. **Call [Print](https://golang.org/pkg/fmt/#Print) instead of [Println](https://golang.org/pkg/fmt/#Println)** to see what happens.
4. **Call [Println](https://golang.org/pkg/fmt/#Println) or [Print](https://golang.org/pkg/fmt/#Print) with multiple values** by separating them using commas.
5. **Remove the double quotes from a string literal** and see what happens.
6. **Move the package and import statement** to the bottom of the file and see what happens.
7. **[Read Go online documentation](https://golang.org/pkg)**.
1. Take a quick look at the packages and read what they do.
2. Look at their source-code by clicking on their titles.
3. You don't have to understand everything, just do it. This will warm you up for the upcoming lectures.
8. Also, **take a tour on**: https://tour.golang.org/
1. Have a quick look. Check out the language features.
2. We're going to talk all about them soon.
