I bought a 500 dollar snowblower and an additional 500 dollars in batteries (about 24A total) and it's totally insufficient.

I've converted to electric for everything but the the snowblower is the only thing Ive considering switching back to gas.

To be fair my driveway is 100+ feet. I think this unit would be fine for a smaller driveway.

5/1 buildings in the US don’t usually use Mass Timber. They use traditional light framing techniques for the 5 wooden floors.

The MSRP of a Camry is less than half that of a model 3 long range.

26000$ vs 57000$

You’re focusing on the price of bitcoin. Bitcoins market cap during Mt Gox was a few billion. Today it’s over a trillion.

Luna going from a market cap of close to 100 billion to basically worthless in a few days is like 50 Mt Gox incidents in terms of wealth destruction.

Bitcoin has market cap swings larger than the loss during Mt Gox in minutes these days.

Have you read the gorilla TSDB paper? https://www.vldb.org/pvldb/vol8/p1816-teller.pdf

It does a good job laying out why TSDBs are used and some of the tricks they leverage to store this type of data. See the requirements for the service layed out in the paper:

• 2 billion unique time series identified by a string key.

• 700 million data points (time stamp and value) added per minute.

• Store data for 26 hours.

• More than 40,000 queries per second at peak.

• Reads succeed in under one millisecond.

• Support time series with 15 second granularity (4 points per minute per time series).

• Two in-memory, not co-located replicas (for disaster recovery capacity).

• Always serve reads even when a single server crashes.

• Ability to quickly scan over all in memory data.

• Support at least 2x growth per year

Lots of organizations want to adopt an SRE/devops model and want a similar system. Also one thing you should know is that trying to accomplish this with traditional DBMS is usually possible but since it is not making specifically optimized trade offs it usually is more expensive and requires a lot of tuning/expertise.

Lots of organizations (even legacy companies) have a massive need for this kind of service. Also there are very cheap options out there than can handle the million metric use case for basically a <100$ a month is infra costs. The use case is definitely there and even if it's possible with traditional DBMS systems, it usually cheaper and more performant to use a dedicated TSDB.

This looks really sharp! Love the opinionated approach to how to handle incidents with assigned roles!

What am I supposed to take away from this story? I'm glad that these adults are having such a transformative experience living in Connecticut with roommates, but it's hard to imagine thinking a story like this should be in the NYTimes.
