The research team at IBM recently announced they've reached a new industry record at 5.5%, using the SWITCHBOARD linguistic corpus. This brings us closer to what's considered to be the human error rate, 5.1%. They used deep learning technologies and acoustic models to accomplish this milestone.
Spotify clients generate up to 1.5 million events per second at peak hours and all are handled by their Event Delivery System, designed to have a predictable latency and to never lose an event, Igor Maravic noted in his presentation at the recent QCon London conference, where he gave a high level overview of the system and some of the key operational aspects.

At QCon London, Matt Heath, Distributed Systems Engineer at Monzo Bank, presented “Building a Bank with Golang”. Key takeaways included: Golang’s focus on simplicity and readability in combination with excellent concurrency primitives making this a language well-suited for creating “high volume, low latency, distributed applications”.
Arnon Rotem-Gal-Oz believes that something is either a monolith or a microservice is nonsense. He also believes that more and more implementations which claim to be microservices will not live up to all of the principles. However, he does not discount the need for semi-independently deployable software components and discusses an approach he has found useful, which he call Aspects.
In a recent blog post, Amazon announced changes to its NoSQL database service, DynamoDB, that includes support for Time to Live (TTL) on data stored in the service. Deleting data, based upon time-based thresholds, provides opportunities for organizations to reduce storage costs for data that decreases in value over time.
