Capturing a billion Emojis 👷♂️
Sports events are crowded - and on the internet even to a bigger degree. The companies who handle the broadcasting are willing to make them interactive so that users can show their reactions to particular events of the show - with emojis of course. To make it happen, there should be some architecture in place. Find a good piece of engineering to solve this peculiar problem.
Uptime Guarantees - A Pragmatic Perspective 👷♂️
How frequently do you hear from the business they need 100% availability? More often than me getting incorrectly called Vlad(that's another name!). How do you turn down such requests? Get a pragmatic perspective: how to reason about the actual availability, how much does it cost to come even to 4 nines(99,99%) and what do the cloud guarantees mean?
DuckDB Hype 👷♂️
A few issues ago I featured a post by Jordan Tigani with the statement that Big Data is Dead. But what is up to the replacement then? EasyData! DuckDB is trying to do the same for data analytics as SQLite doing for transactional processing. Easy, small, embeddable, lightning fast - all of this is about DuckDB. Check out the post by Oliver Molander where he analyzes all the hype around it.

Predicting demand at Airports 🤟
The taxi operators at airports face a problem: if there is not enough demand, drivers waste their time. If there are not enough taxis though, the experience for riders is unpleasant. Uber is trying to solve this problem with Machine Learning and predictive models. In this article you will find the formulas and the reference architecture for it, but I still wonder why checking out the arrivals table is not sufficient.
Operating Lambda: Performance Optimization 👷♂️
When you start using Lambdas, the first problem you observe is a long startup time. A typical solution is to schedule an event which will ping your function every once in a while to ensure a warm environment. However, this solution is not universal: it does not help during increased load or starting a Lambda in a different AZ. Grab the read about available performance optimizations for Lambda and the anatomy of Lambda's start.
