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.

Working on a newsletter edition about deliberate practice.
Deliberate practice is crucial if you want to reach expert level in any skill, but what is it, and how can it help you learn more precisely?
A thread based on @augustbradley's conversation with the late Anders Ericsson.
You can find my complete notes from the conversation in my public Roam graph:
https://t.co/Z5bXHsg3oc
The entire conversation is on
The 10,000-hour 'rule' was based on Ericsson's research, but simple practice is not enough for mastery.
We need teachers and coaches to give us feedback on how we're doing to adjust our actions effectively. Technology can help us by providing short feedback loops.
There's purposeful and deliberate practice.
In purposeful practice, you gain breakthroughs by trying out different techniques you find on your own.
In deliberate practice, an expert tells you what to improve on and how to do it, and then you do that (while getting feedback).
It's possible to come to powerful techniques through purposeful practice, but it's always a gamble.
Deliberate practice is possible with a map of the domain and a recommended way to move through it. This makes success more likely.

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.
1/16
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:
2/16
"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.

A thread about online teaching and learning (T&L).
@wv012 @Passengercis @thebandb @carelstolker @BieTanjade @C4Innovation @rianneletscher @PietVdBossche @wijmenga_cisca @Pduisenberg @QMProgram #highered #edtech #teaching @threadreader unroll (1)
Here is a university road map on how the strengths of conventional, face-to-face teaching and online T&L can be optimally used to address today’s lecture room challenges.
I am not an instructional designer, but I have been teaching online internationally for over 10 years (2)
In the last 2+ years, I taught hybrid & online undergraduate courses at the University of Maryland Global Campus, among the largest top-20 online colleges in the USA.
UMGC has received numerous awards for its innovations: https://t.co/jd7JkHIK8Q and https://t.co/IPKizZwclA (3)
15+ years ago UMGC was one of the founding members of QM “Quality Matters” a non-profit with 1,500+ members in 26 countries.
QM offers membership of a community of practice, numerous free resources, online training, and review/accreditation services https://t.co/ZoFVsgcBC7 (4)
It is obvious that universities will also be affected by the 4th industrial revolution, and things can not stay the same as they were after the invention of the printing press.
Until recently, a lecture room looked the same as 900 years ago incl. flirting and sleeping (5)

Speech Delay is most common in children nowadays
In ancient times, our grandparents used to follow typical natural way of caring the needs of a child. All they used were more of natural products than chemical based for the growth of child.
One of major step followed was to feed Gurbach Jadd/ Vasa Kommu/ Acorus Calamus for initiating good speech ability in a child. This stem was needed to babies on Tuesdays and Sundays in mother's milk.
Vasa is feed to baby after the 1st bath on 12th day in week. Weekly only thrice it is fed and named as :
Budhwar - Budhi Vasa
Mangalwar - Vaak Vasa
Ravi Vaar - Aayush Vasa
This stem is burnt and rubbed against the grinding stone in mother's milk or warm water to get a paste
The procedure to make it is in the link
https://t.co/uo4sGp7mUm
It should not be given daily to the child. Other main benefits are
1. It clears the phlegm in child's throat caused due to continuous milk intake. It clears the tracts and breathing is effortless.
2. Digestion
For children who haven't got their speech and is delayed than usual should feed this vasa on these days in week atleast for 6months. Don't get carried away with this dialogue
"Some gain speech little late"
