Hey! I'm Sylvain Kerkour 👋
This is my personal site where I write about how to (ab)use technology for fun and profit: using it to your advantage to make money online and find simple and elegant solutions to the hard problems of modern life ☀️
- Programming: With software we can introduce automation and scale into our life, which allows us to work less and more efficiently.
- Hacking: In order to build great stuff, prevent attacks and defend ourselves we need to understand how to break (into) things.
- Entrepreneurship: Having your own online business lets you live on your own terms. You do what you want, when you want, where you want. You don't have to ask the permission.
