Engineering Director @MongoDB. I like building things, solving problems and playing games, occasionally at the same time. Opinions are my own.
It's personal in a way checkbook isn't, so people have opinions or think they can generalize from their limited family experience and want to share with someone who might validate their knowledge.

The thing that gets me is people reposting and complaining about tweets. If you left Twitter for its toxicity, why bring it here?

Rates vs levels.
The inflation RATE is down but PRICES are noticeably higher than before.
Most people experience prices, not rates.

Many of the features of the other site aren't here yet. Adding new feeds ("My Feeds") is very useful. I have one called "Home+" that's pretty good.
If you get feeds for popular stuff, be prepared for a lot of raunchy content. It's the wild west here, still.

I get lots of signal reading 3 star reviews. Paid reviews are 5. Angry reviews are 1. But 3's come from the rare and wonderful souls who get something personally satisfying out of a nuanced take.

So... maybe we get a lot more shitty code written by people faking it with an LLM copilot. Which leads to more bugs, which leads to more tickets, which leads to more code to write → PRODUCTIVITY! 🙃

That said, I did my first real coding in partnership with ChatGPT today. I am not a front end dev, but had a prototype visualization with JS and D3 in an hour or so via dialog with the AI. I'm sure it would have taken me many more hours if I did the research and learning myself. Impressive!

We also got enormous amounts of bloat and complexity, where UX works at a similar speed to decades ago despite Moore's Law.
More productive in terms of what? Lines of code? Tickets closed? More apps in the app store? More feature bloat? More A/B tests? 🤷

You can imagine the opposite to crystallize the difference. Let's say a request requires N microservices in some DAG each fronted by an LB and randomly backed by M AZs. If N >> M, then every request will have at least some calls routed to a sick AZ.
Cells shard the routing so the DAG is in one AZ.

I think this was the key bit:
"All services are present in all AZs, but each service only communicates with services within its AZ. Failure of a system within one AZ is contained within that AZ, and we may dynamically route traffic away [from an AZ] by redirecting at the frontend."

The big problem that doesn't seem solved is drivers who get matched with you then drive away without canceling, apparently trying to get you to cancel first. ("cancel chicken" I call it.)

The teams I support at MongoDB are effectively "location-blind" (at least within a broad timezone band). If someone we hire happens to be in a location with an office, they're welcome to be in person, but it's not a factor in interview selection.
