    Many exciting new static types will be coming to 3.8. PEP 589 makes TypedDict (my baby!) standard. PEP 586 introduces Literal types. Shout out to the great work by , , and others!

    The future rewards those who press on. I don't have time to feel sorry for myself. I don't have time to complain. I'm going to press on. ~ Barack Obama

    Thus I mainly see value in *compiled* Lisp dialects rather than uncompiled ones.

    Lisp’s special advantage over other languages - macros - is an abstraction tool that I speculate only really provides especial advantage in *compiled* contexts, allowing trading a compile time performance hit for runtime performance boost, unlike functional abstraction.

    Nevertheless I am reluctant to recommend Hy itself on the merits: It is an *uncompiled* Lisp.

    Props to the Hy folks (Lisp in Python) for making such an entertaining quickstart and tutorial, with emotion and jokes.

    Yes. Code-*reading* skill is undertaught but extremely important.

    Another longtime Mac developer shutting down: Orbicule, the makers of Undercover, a tracker for stolen laptops. Seems that competing with Apple's FindMy service finally did them in.

    Really neat proposal for a “nanoprocess” isolation boundary around modules inside programs. Allows protecting against vulnerable dependencies.

    It's bittersweet: I'm leaving , and am now retired. I've learned a lot during my time as an engineer here -- e.g. type annotations came from this experience -- and I'll miss working here.

    We’ve made the decision to stop all political advertising on Twitter globally. We believe political message reach should be earned, not bought. Why? A few reasons…🧵

    But be cautious when giving negative feedback: Always target a person’s actions rather than attacking the person themself. If you attack the person they may come to fear you, become risk averse, and never dare to shine brightly.

    If you don’t give feedback to your mentees when they make mistakes, they also will never learn.

    On and allowing mistakes: If you always protect your mentees from making mistakes, they will never learn.

    I have rediscovered that time fragmentation is a huge productivity drain. Counter with daily calendars (with hourly focuses/tasks) and timecharts. More on timecharts:

    My university just announced that it’s dumping Blackboard, and there was much rejoicing. Why is Blackboard universally reviled? There’s a standard story of why "enterprise software" sucks. If you’ll bear with me, I think this is best appreciated by talking about… baby clothes!

    Want a good API? Try test driven development, or even better, README driven development.

    With the right platform and teachers, you can turn the youngest learners into Computer Scientists 😉👩🏻‍💻

    Today our coding adventures with taught us how to make Breeze spin at 20 degrees while moving to the right, then hide and reappear with a “sparkle” sound. Wow! These coders are quick learners! 💚🐬🖥
