One gap I kept running into: most Go resources teach syntax well, but stop before things actually look like production.<p>So I built the course I wish I had.<p>You build a real app from start to finish: a blog with authentication and an...
I built a Python tool to defer heavy batch ETL jobs (like Snowflake/Airflow) when the local energy grid is "dirty" (high carbon intensity). It uses real-time grid APIs to find green windows. Would love feedback on the logic!
