Arista goes big with network observability platform
Arista’s new network observability software aims to reduce human error, accelerate problem resolution, and streamline root cause analysis of network events and their impact on application performance.
Improving Network Performance with Linux Flowtables
We’re building an open source alternative to AWS. For IPv4 assignment and firewall rules, we use Linux’s Netfilter / Nftables. This subsystem provides a powerful way to handle packets addressed to the host. We recently came across flowtables - a network acceleration feature in the Linux kernel that works like a routing cache. When we introduced flowtables into our stack, it reduced network latencies by 7.5%.
What are GADTs and why do they make type inference sad?
Back in 2020, I created Cubiml, a simple ML-like language that demonstrated how to extend the usual Hindley–Milner type system with subtyping while still having decidable full type inference. One question I got was whether it would be possible to support generalized algebraic data types (GADTs) in Cubiml. I had heard that GADTs break type inference and didn’t see the point, so I didn’t think much of it at the time.

Tigris is a globally distributed S3-compatible object storage service that provides low latency anywhere in the world, enabling developers to store and access any amount of data for a wide range of use cases.
Researchers disclosed multiple potential vulnerabilities that may impact some AMD processors, including Zen-based product lines across multiple generations.
Safer Image Builds with Cloud Native Buildpacks and Wolfi
This post discusses how to create containers that are smaller and more secure by including Wolfi as the base image when creating containers using Cloud Native Buildpacks.
In the previous part we've talked about message brokers in general and I hope you got a brief understanding of how they work and why you'd need them. In this article, we're going to dive deeper and explore one of them - **RabbitMQ**.
Inside Minority Report's 'Idea Summit,' Visionaries Saw the Future
Three years before making Minority Report, director Steven Spielberg assembled a supergroup of deep thinkers who conceptualized many of the movie's most enduring visions of the future. A virtual roundtable takes you back to that momentous event in the history of sci-fi filmmaking.
