Citi reduced Mongo power footprint by 50%, 5000 instances, plus also 15% performance - ASK MARCEL MITRAN FOR THIS

I was trying to understand the figures, so I asked “why does this one use less carbon?” The answer? “Because it’s faster.”

This is, initially, counter-intuitive. For something like buying a car, there are hard choices. Should we get the muscley one with the bigger engine that goes vrrroooom, or should we get the economical one that preserves fuel and goes put-put-put?

“Performance is the art of avoiding work” - Stale Pederson The car is faster because it uses more resources. Quarkus is faster because it’s more efficient.

Of course, there’s always a trade-off. With Quarkus, there is a trade-off, but it’s not the tradeoff I expected. When running on JVM, Quarkus uses about half the memory footprint of a traditional cloud native framework, and starts about four times faster.

Counter-intuitive. TANSTAAFL. https://en.wikipedia.org/wiki/There_ain%27t_no_such_thing_as_a_free_lunch

“Finer-grained conditional builds” Shorter, smarter, builds does seem like it would be such a massive win, doesn’t it? So much compute power is wasted on compiling things that didn’t change and then running tests that aren’t interesting … all while slowing down the feedback cycle for engineers.

[![“Yep. Climate solutions are just better ways to do the things we want to do.

Unless you are a major shareholder in an oil company or something, most climate solutions will make your life and your community better. Quote Tweet Brady Faught @Bradyfaught · 4h I’m learning the decades-long message that “we must sacrifice our lifestyle to save the planet” is wrong:

• EV’s are better
• walkable cities with clean air are better
• induction cooking & heat pumps are better

What needs to be done is not sacrifice - it’s advancement”](foley-tweet.png)](https://twitter.com/GlobalEcoGuy/status/1549989438142517248?s=20&t=RHDNuiSmnr6oGhQsW15eQw)

These are called co-benefits.

IKEA is a climate success story: it has slashed its carbon footprint by 30 percent in the last ten years while growing its profits 24 percent over the same period. “There is a very strong myth in society today that climate smart comes at a premium,” Jesper told Time. “Now, it’s quite easy to dismantle that myth.”
