Today is a good day; we do an internal AWS GameDay to explore potential Fargate and RDS failure scenarios. This is so much fun 🤩 The AWS Fault Injection Service is just awesome.

In case anyone was wondering why the government was so heavily invested in scientific research (pre-DOGE) here is a clear explanation from one of the workers on the chopping block:
A Reddit post  by user Throwawayainteasy: I get exhausted trying to explain this stuff to people who fundamentally don't understand pure scientific research.

It's mostly not profitable, at least in the short-term. Some of the most important scientific breakthroughs are things that we won't really understand the value of until 10-20 years from now or more. Possibly generations.

That's just the nature of science. It can even be true for the seemingly mundane stuff. In the 60s someone gets curious how flies can get around so well with such tiny brains, that answer turns into new understandings, those understandings merge with new computing, and in the 2020s we have autonomous drones and self driving cars who's existence is rooted all the way back to someone's unheralded research that started because they thought bugs were neat.

No for-profit company would fund the first 20 steps in that process, because there's no clear path to profitability until the end. That's why governments across the world are the primary funders of pure research.

“It is a coup, executed not with guns, but with backend migrations and database wipes.” We face “a dangerous alignment of anti-democratic thought with immense technological and financial resources.”

You can't please or argue with people who have no grace, who know no shame, whose only currency is outrage. Call them out on their bullshit, name it clearly. Do not apologize for it. Do not expect apologies. They want to wear us down. We must not yield. *WE* are what's on the line. All of us.
