A version of this post originally appeared in Refactoring , a Substack offering advice for software engineers. I think their existence is what explains the curious durability of the notion of a 10x engineer, someone who is 10 times as productive or skilled as their peers. At one point, I was a pretty good database reliability engineer.
The US Environmental Protection Agency (EPA) will evaluate whether emissions from piston-engine aircraft operating on leaded fuel contribute to air pollution that endangers public health and welfare. The agency plans to issue a proposal for public review and comment in 2022 and take final action in 2023.
Under the Clean Air Act, EPA reviews information on air pollutants and sources of air pollution to determine whether they threaten human health or welfare. Piston-engine aircraft are the largest single source of remaining lead emissions to the air in the US, contributing 70% of the lead entering the air annually.

People might be bored reading about the Prius but a review on four Priuses (2004, 2005, two 2006s) that my family owns that ran a total of 913k km (570k miles) should be interesting, right? We only drove ’normal’ ICE (Internal Combustion Engine) cars before but those gave me a feeling of always being in a hurry.
