FAQs
What is the difference between these courses (paid) and the content on YouTube?
Some lectures from different courses have been put on YouTube as Preview. The are not structured and jump to a topic. The Courses in the Subscription are well structured and focused on developing a skill.
Is this recommended for beginners?
Yes! The courses are taught as if the learner has no idea about the subject. Each course starts of by ensuring that the basics needed to understand the followup lectures is understood.
Why a subscription model?
We are billed for the hosting and bandwidth by the platform provider. While we would very much like to offer lifetime validity, given the recurring bills, we have to ensure we continue to earn enough to be able to fund the effort and bring more value to our learners. The Monthly plan is for those who cannot afford the yearly subscription but can benefit from burst learning. To get the most out of our content, we recommend subscribing to the yearly plan.
Do I need a special machine configuration to take this course?
No! All you will need is an internet connection and the Chrome browser. The hands-on examples and lab work is based on GitHub codespaces platform. We use GitHub Codespace to ensure that you don’t struggle with the setup and focus on the learnings. You are always free to setup the environment locally. Although, we won’t support that, but you are free to do so. The courses, as much possible use a Emulator target of a real board, so if you wanted to run the code on real board. You can do so.
Why is a GitHub account needed?
The Experiments and Labs are based on the GitHub provided Codespaces virtual machine. Codespaces will enable a common work environment for all the learners and avoid the hassle of special setup.
Can I change my email-id post purchase?
As much as we’d like to support that, your account will be linked to your email-id post purchase.
What name will be printed on the Certificate?
The name you use on the platform will be printed as is on the Certificate when it is generated.
Can I follow the steps on my own PC?
Yes for the most part. Better yet would be if you have a linux machine.
I previously purchased a course from inpyjama/pyjamabrah, any discount for me?
Yes. We can offer a discount on the yearly subscription. Please reach us at support@pyjamacafe.com and be sure to include the details of your past investment. We will work on a custom discount for you.
