Great session by @MarcJBrooker earlier on building technology standards at Amazon scale, and some interesting tidbits about the secret sauce behind Lambda and how they make technology choices - e.g. in whether to use Rust for the stateful load balancer v2 for Lambda.
🧵
The interesting Q is how to balance technical strengths vs weaknesses that are more organizational.
which is basically the same question that organizations all over the world have to answer when they consider adopting #serverless technologies like Lambda.
As a consultant, I often find myself being one of those guard rails for organizations that want to adopt #Serverless
(nice plug, self hi-five! ✋)
This line about avoiding baking language-specific choices into your contract and data is so important. It gives you an easier path to back out of that language choice if it turns out to be wrong.

"We use standards very sparingly, only in areas where we deeply understand the context and innovation has little upside"
This, so much this👆
Why? because incentives drive outcomes.
That's why the ivory tower architect is such a bad model - they make all the decisions but you're on the hook for it.
And that's how many organizations has adopted #serverless successfully, starting with one success story.
Love to see more details on how formal methods is applied here.

When the university starts sending out teaching evaluation reminders, I tell all my classes about bias in teaching evals, with links to the evidence. Here's a version of the email I send, in case anyone else wants to poach from it.

When I say "anyone": needless to say, the people who are benefitting from the bias (like me) are the ones who should helping to correct it. Men in math, this is your job! Of course, it should also be dealt with at the institutional level, not just ad hoc.
OK, on to my email:

"You may have received automated reminders about course evals this fall. I encourage you to fill the evals out. I'd be particularly grateful for written feedback about what worked for you in the class, what was difficult, & how you ultimately spent your time for this class.
3/16
However, I don't feel comfortable just sending you an email saying: "please take the time to evaluate me". I do think student evaluations of teachers can be valuable: I have made changes to my teaching style as a direct result of comments from student teaching evaluations.
4/16
But teaching evaluations have a weakness: they are not an unbiased estimator of teaching quality. There is strong evidence that teaching evals tend to favour men over women, and that teaching evals tend to favour white instructors over non-white instructors.

Last month I presented seven sentences in seven different languages, all written in a form of the Chinese-character script. The challenge was to identify the languages and, if possible, provide a
Here again are those seven sentences:
1) 他的剑从船上掉到河里去
2) 於世𡗉番𧡊哭唭𢆥尼歲㐌外四𨑮
3) 入良沙寢矣見昆腳烏伊四是良羅
4) 佢而家喺邊喥呀
5) 夜久毛多都伊豆毛夜幣賀岐都麻碁微爾夜幣賀岐都久流曾能夜幣賀岐袁
6) 其劍自舟中墜於水
7) 今天愛晚特語兔吃二魚佛午飯
Six of those seven sentences are historically attested. One is not: I invented #7. I’m going to dive into an exploration of that seventh sentence in today’s thread.
Sentence #7 is an English-language sentence written sinographically — that is, using graphs that originate in the Chinese script. I didn’t do this for fun (even though it is fun), or as a proposal for a new way to write
I did it as a thought experiment. Why? Because thinking about how the modern Chinese script might be adapted to write modern English can give us valuable insights into historical instances of script borrowing, like those that took place centuries ago in Japan, Korea, and Vietnam.

The following sentences are in seven different languages, all written in Chinese-character script (or a modification of it). Can you identify the languages?

That this sentence is a written form of English is undeniable, as the sentence is made up entirely of English words following the rules of English grammar. 23/
