This article predominantly talks about testing as a distinct career option in data science and machine learning (ML). It gives a brief on testing workflows and process. It also depicts the expertise and top-level skills a tester needs to possess in order to test a ML application.

Dedicated hosts for macOS are now available on CircleCI. This new layer of support is built exclusively for macOS and offers Apple developers unprecedented storage, security, and scalability on CircleCI. By reserving a dedicated host, teams can unlock access to a bare metal instance that provides exclusive access to an entire host machine for 24 hours.

Matt Gordon is a Microsoft Data Platform MVP and the Director of Data and Infrastructure at Rev.io. The sophisticated billing-as-a-service (BaaS) platform provides online billing software to communications companies, IoT businesses, and technology service providers. Matt’s role, first and foremost, involves keeping the lights on while at the same time overseeing many data-related projects, from architecture to performance tuning and DevOps implementation.

“End of life, end of support, pandemic-induced shipping delays and remote work, scanning failures: It’s a recipe for a patching nightmare.”, federal cybersecurity CTO Matt Keller says. Ensuring a high level of security for your IT infrastructure and being sure you have not missed something is hard to arrange during these days. A zero-day exploit happens when hackers identify a software weakness or a security gap and take advantage of it to perform a cyberattack.

Grafana k6 is our open source tool to help you ship reliable applications by doing performance testing in a modern and developer-friendly way. Performance testing is still unknown to many, but it is not a new topic. In fact, performance testing courses are everywhere — even at colleges and universities. One of our passions is to educate others on the best practices of performance testing, working together with the Grafana k6 community.

Developers love containers for their portability and flexibility. Suitable for today’s cloud-native environment and agile development requirements, containers make it super-fast to develop, test, and run applications. Besides this, they are lightweight and can optimize the platform (and the host OS) they are deployed on. Now, for powerful applications with hundreds of containers, the platform should also be portable, flexible, extensible, and efficient.

Ensuring that networks and the applications they enable are performing as well as they should is a full-time and challenging task for system administrators. We've all encountered scenarios in which end-users complain that an application is slow. Then the network team says it's not their problem, and the development team (or third-party application vendor) also says it's not their problem either.

Mattermost v6.4 is generally available today and includes the following new features (see changelog for more details).

The right tools enable your team to ship amazing code quickly. But between building, deploying, testing, monitoring, and maintaining software, all those great tools can create a lot of stuff to keep track of. Luckily, there’s a solution to this problem: ChatOps. ChatOps is a collective approach to running DevOps workflows and building a collaborative team culture.
