The adoption of eBPF (Extended Berkeley Packet Filter) has revolutionized high-performance applications, tracing, security, and packet filtering within the Linux kernel. Specifically, TC-BPF, a type of eBPF program attached to the Traffic Control (TC) layer, has emerged as a powerful tool for packet manipulation in both ingress and egress. This blog delves into the practical application of TC-BPF to redirect DNS queries in a Docker environment.

Hey there! We're back for our third edition of Tips and Tricks. As we said in our first posts on Drizzle ORM and Template Databases in PostgreSQL, our new Tips and Tricks mini blog series is going to share some helpful insights and cool tech that we've stumbled upon while working on technical stuff. Today's topic is short and sweet. It'll be on CPU utilization and what that metric indicates. If you enjoy it and want to learn more, I encourage you to check out the "further reading" links.

One of the worst-kept secrets among data scientists and AI engineers is that no one starts a new project from scratch. In the age of information there are thousands of examples available when starting a new project. As a result, data scientists will often begin a project by developing an understanding of the data and the problem space and will then go out and find an example that is closest to what they are trying to accomplish.

Functional testing is important in the software development process and is employed by around 90% of development teams, according to Huttle Research. It ensures software performs as intended through different methodologies such as white box, black box, and gray box testing. However, choosing the right approach can be complex, involving considerations like project requirements, team expertise, and specific software characteristics.

Logging is an integral part of software development, providing developers with valuable insights into the behaviour and performance of their applications. In the Go programming language, various logging libraries, such as the standard library’s log package or third-party options like logrus , zap and zerolog, facilitate the generation of log output.

In today’s subscription-driven economy, flexible billing options are crucial. While traditional post-paid models are widespread, pre-paid credit-based billing is gaining popularity. This approach empowers businesses to bill customers upfront for a set amount of usage, offering an alternative way for customers to pay for your service.
