GREAT example by Yuan
Games is actually a fantastic example of what happens when you remove the obstacle that everyone thought was the biggest hurdle in building a game: needing to build a game engine
Easier to build games… still very hard to build great games!

I was at @evernote.bsky.social when they started migrating to React Native in 2018. Against all advice from tech leads the SVP of engineering (coming from Amazon) pushed through. The quality of the Android app went downhill over the years not only performance wise.

There are 21 million Black people in the US.
Fewer than 6% of us earn over $100K a year.
The median net worth of Black households fluctuates between about $20K and $40K, depending on how much scamming happens that year (eg crypto, asset forfeiture).

More to say on burnout and I'm probably going to boost it a few times because folks need to hear it:
Burnout is a form of brain damage. It happens when stress conditions persist until they damage our brains.
It's an injury that needs to heal, not a weakness that needs to be pushed through.

Man burnout can mess you up for a very long time.
And it can sneak up on you: things can seem stressful but mostly manageable until suddenly they're not manageable.
Self care and vacation are great, but they're guardrails: they don't help when you've already fallen in.

This is so on point. So many use cases are barely working reliably (if that) with state of the art models and non-deterministic operations makes testing a beast.
I cannot begin to imagine trying to build apps on anything that's not top of the line.

The first bullet point is "it's cheaper." That only matters once you've built something successfully and need to scale it. First, you need to figure out whether a thing is even possible, THEN you figure out how to optimize the economics, generally speaking.

@danabra.mov the Bluesky language translate experience isn't super great right now. I assume you're trying to avoid Google translate api costs by forcing a web link.
Consider the MLKit translate SDKs (free and on device translations) and then do web fallback.

Personally, 2024 was finally the year of Linux on the desktop. After years of dual booting (mostly for gaming), I've been running Universal Blue images (atomic distro based on Fedora Silverblue) all year without issue. Modern game tech, enthusiast hardware, & game compat on launch are pretty good.

Universal Blue is a diverse set of images using Fedora Atomic's OCI support as a delivery mechanism. That's nerdspeak for the ultimate Linux client!
