If you add a link like the following to your page, feed readers should be able to discover your RSS feed

    <link rel="alternate" type="application/rss+xml" href="/engineering/feed/" />

Excellent, this works perfectly. Thanks!

It seems like Khan Academy changed their blog to Wordpress and they no longer have an RSS feed.

I've used mypy and pyright. Mypy generally "just works" for all the Python idioms I use, while pyright is less reliable.

Pyright's VSCode integration, Pylance, provides a great auto complete experience. So I use Pyright for autocomplete in VSCode and mypy for type checking.

Which NoSQL store are you talking about regarding fast aggregations? I don’t think that’s a property of all NoSQL dbs.

Those tools are not re-implementations of mypy, but their own type checkers. Pyre doesn't necessarily have all the features of mypy and vice versa.

You can use typing.TypeVar for the `pow()` example. TypeVar was added via the original type hints PEP in 2014.

    from typing import TypeVar

    T = TypeVar('T', int, float)
    def pow(base: T, power: T) -> T: ...

GitHub's $4/user/month pricing is very hard to compete against and actually make money as a business. Charging half the price of GitHub for example isn't sustainable.

OT: this blog could use RSS.

Why didn't you use Pydantic with Django if the DRF serializers were too slow?

You can also skip the object serialization from the ORM and work with python dicts directly to significantly improve serialization performance from the database.

You can purchase a license through the app. I don't think you can get one through the website.

Intersystems purchased Trakcare, which was developed by an Australian company. They'd love to sell it in the US, but Epic is Intersystems largest customer and they have an agreement to not compete in the US.

Cache is the most archaic and least usable programming environment I've ever experienced. Unit tests are not a thing. MUMPS, which underlies the whole system, is stringly typed. The entire stack is junk, so it's no surprise that Trackcare is either.

> It’s worth noting that HAProxy can integrate with Consul’s DNS interface, but this adds lag due to the DNS TTL, it limits the ability to use Consul tags, and managing very large DNS responses often seems to lead to hitting painful edge-cases and bugs.

I was surprised how they dismissed HAProxy integration with Consul using SRV DNS records. Can anyone confirm the problems they highlight?

It seems like their service that broke would not be needed if they went the DNS route.

Anyone know how to enable this new UI?

Another great post! I'm curious what people would suggest as a tech stack that's not python/gunicorn. Something with a GC, decent ORM, that can replace database-backed services written in Python with similar high level code.

It would be great if you could add an RSS feed to the blog.

Additionally any deploy will give users a moment of downtime because Heroku only supports rolling deploys on paid dynos.

This project appears to have a dependency on pandas.

It's the _default_, as they say in the article:

> There is no mandated development environment. Some developers use vim. Some use Emacs. And even more engineers use our internal, unified development environment called Nuclide.

off topic: It's annoying how the Twitch blog linked in the article doesn't have an RSS feed. How do people read these blogs without one?

Why wouldn’t you return more data for the REST API instead of making dependent requests?

What languages are you using with Bazel? I have a project that uses Typescript and Python. Are you using Bazel with interpreted languages?

Have you tried https://docs.python.org/3.9/library/2to3.html? It should automate some of the syntax conversation.

You can also write custom transforms with 2to3 but I've found https://pybowler.io is a decent wrapper. I haven't used it for 2to3 conversion though.

You can create a genius (or maybe it’s called smart) playlist in iTunes that is ordered by recently added. It does exactly what you need.

It's MongoDB Compass, a client for Mongo.

That's a great idea. I would definitely use a service like that.

I feel your comment isn’t very constructive and is a little demeaning.

I've used the same mic array and the provided software isn't great. In fact it's terrible, but ODAS[0] is amazing. It's super accurate, can track/isolate multiple audio sources, and has a web ui to visualize it. They also have config specifically to handle the respeaker and raspberry pi.

It's not just performance!

Using percent formatting is superior in many ways:

- errors that occur in formatting a message will be logged instead of raising an exception into your application

- error reporting services like Sentry can properly aggregate events

- interpolation won't occur if you don't have the logging level enabled

- it's recommend by the Python docs: https://docs.python.org/3/howto/logging-cookbook.html#use-of...
