What Are Web Cookies? The Privacy and Security Risks of Internet Cookies

This article has nothing to do with chocolate chips or sprinkles. Sorry about that. Instead, we're talking about computer cookies and how too many web cookies can be bad for your online health. While cookies are enormously helpful and necessary for an easy-going web experience, they are not all good, and many pose some genuine privacy concerns.

Metric Correlations on the Agent

As of v1.35.0 the Netdata Agent can now run Metric Correlations (MC) itself. This means that, for nodes with MC enabled, the Metric Correlations feature just got a whole lot faster! The Netdata Metric Correlations feature uses a Two Sample Kolmogorov-Smirnov test to look for which metrics have a significant distributional change around a highlighted window of interest.

Tech Ops is a mess. Here's why we're committed to fixing it.

Building software is hard. Building cloud software is even harder because things move much faster — and require mission-critical reliability and availability. To effectively build software in the cloud, engineering teams need observability, CI/CD, reporting, and lots of tooling. At every organization I’ve worked at, we’ve needed a system of tools that lets us: But all the tools available to engineering teams never quite fit together with our specific processes.

Mattermost Playbooks How-to: Software Feature Development

For teams that follow a structured build and release cycle, having a reliable, shared workflow makes the difference between chaos and consistency. With every new feature in development the team needs to know what the specs are, how it fits in the roadmap, what the customer feedback was, where to find the repository, who is responsible for each step, and so much more.

Master IoT software updates with validation sets on Ubuntu Core 22

If you are packaging your IoT applications as snaps or containers, you are aware of the benefits of bundling an application with its dependencies. Publishing snaps across different operating system versions and even distributions is much easier than maintaining package dependencies. Automated IoT software updates make managing fleets of devices more efficient.
