ALE, the Apprentice Linux Engineer track, is a tutorial series driven by volunteer professional speakers who present apprentice-level material in a way that beginners can understand and use the information. Most tutorials also provide hands-on training, usually with embedded hardware designed and built by ALE volunteers - this is the only associated cost, other than conference attendance fees. ALE made its debut at SCALE 16x in 2018 as E-ALE (Embedded). Since then it has also grown to include IOT, Cloud, and Linux kernel subject matter at a variety of conferences worldwide.
