👏👏 @SenDuckworth excellent speech. Wish it was carried on the main channels so more people could hear what you have to say.

CTO: If we move our repo to a hosted service, what do we do if someone manages to get code into our product? Me: So, like, they check it in, it passes code review, QA, change control approvals, and is deployed through our automation? CTO: Yes! Me: Send them a 10-99, I guess.

In distributed systems, there is no true HA, only probabilities of failure and failure models. Just like life, in distributed systems, no one gets out alive.

I've seen it happen even with a CI server...but people add skips for known failing tests or ignore the results and push anyway. :( Its really hard to find the source bug when you're dealing with a failed integration job with dozens (or hundreds) of components.
Replying to @housecor
The longer it takes before realizing the tests were broken in some previous merge, the harder it is to fix them. This setup tends to happen on teams that are "too busy" to setup a CI server. Yes, setting up CI takes some extra time up front. But it saves time in the long run.

I can't tell you what your next major incident will look like, but I can tell you that some aspects of it will be entirely novel and other aspects will be distressingly familiar.

Thank you to those who do postmortems. *Especially* for large mature teams. There are not better high-level learning materials for understanding how real systems at scale work. Your reports educate the next generation of infra Students: read all postmortems like this, be ye wary
The post mortem of today’s @Cloudflare outage is up: it’s a sobering read. - testing in production (dark launch) isn’t without its perils. It can take down your production - don’t do *global* deploys, even for staged rollout of feature flags/dark traffic. bit.ly/2FQN77k

The most insidious thing about the whole sneering at a politician for being a bartender thing is that we are *supposed* to be governed by everyday citizens. The only major qualifications needed for Congress is to be an American and to have the support of your fellow Americans.

Next up, NOVA presents "BACK TO THE MOON" on July 10, showcasing the newest generation of engineers who hope to use the lunar surface as a stepping stone to long-duration space travel -- to Mars, the Asteroid belt, and further into our solar system. #Apollo50 #SummerOfSpace #PBS

Media companies need to do less flying in of white North Americans and more recognizing the people who live there — find ways to help them tell their own stories about what is happening to them
The title “foreign correspondent” has long been synonymous with whiteness, maleness, and imperialism—journalists fly in from North America, Europe, and Australia to cover the poverty and wars of the non-Western world, writes @Pri_Borpujari cjr.org/special_report/fixer… via @cjr

This is such a great piece, serious questions about authorship and attribution in the context of journalism's use of fixers are asked and should be considered deeply by western publications.
International publications should hire local reporters to be foreign correspondents. "Every story from a foreign location in an international pub bears the fingerprints of an unnamed local journalist without whom that story wouldn’t have been possible." cjr.org/special_report/fixer…
