Thanks for this Alex! Will definitely check this out. DynamoDBGuide.com was a huge help to me when I was learning serverless last year to build wanderium.com. There's definitely a learning curve for DynamoDB but the performance is really good.

Do you talk about the best way to do aggregations in your book? That's one of the more annoying downsides of DynamoDB that I've kind of had to hack my way around. (I combine DynamoDB streams with a Lambda function to increment/decrement a count)

It's unfortunate for Hipmunk to just be turned off despite its founders trying to buy it back: https://skift.com/2020/01/14/hipmunk-co-founders-spurned-by-...

Flights are hard, and it's why we're staying away from flights at first for my travel startup Wanderium (wanderium.com). Instead we're focusing first on the "long tail" of travel issues: visas, vaccinations, safety, local customs, infrastructure, etc. By aggregating all of this data in a single place and presenting them in a single, personalized experience we think it can save travelers many hours per trip.

I find it a bit funny how many people in here think Disney sucks now. The tech/developer crowd clearly is not their audience (which is fine). I personally think Disney has done a good job with the Marvel acquisition by taking some pretty unknown characters and turning them into heroes on par with Spiderman which 10-15 years ago would be unbelievable. The Last Jedi on the other hand I thought was meh. Leia floating through space? That's pushing it.

Anecdotally, I was just at Disneyland on a weekday recently and it was as packed as can be, and among my friends who aren't at in tech many of them are diehard Disney fans and are super excited for Disney+ (especially their new show Mandalorian). Considering Disney's track record at the box office the last 5 years I expect Disney+ to do well.

In most states dealership cars typically have dealer plates which only allow them to be driven during test drives or by dealership employees. How do you handle that?

For a great in depth but still understandable look at the race to zero emissions, including carbon capture technologies, I highly recommend this series from Quartz: https://qz.com/on/race-to-zero-emissions/

It seems increasingly likely with every one of these reports that our usage of plastics has lead to the large drop in sperm counts the last few decades: https://www.gq.com/story/sperm-count-zero
