CircleCI’s scheduled pipelines let you run pipelines at regular intervals; hourly, daily, or weekly. If you have used scheduled workflows, you will find that replacing them with scheduled pipelines gives you much more power, control, and flexibility. In this tutorial, I will guide you through how scheduled pipelines work, describe some of their cool use cases, and show you how to get started setting up scheduled pipelines for your team.

The database/sql package in the Go standard library maintains a pool of connections so that all queries going through a single *sql.DB instance will reuse the same pool. This is great because you get a connection pool out of the box. But what if you need to share the same connection pool across processes? How do you use the same API in different processes but still reuse the same pool?

Rancher Desktop has been in development for just over a year with the open question: when do we have a 1.0.0 stable release? Along the way the scope has expanded, it was ported to run in more places and the development team has grown. All of this happened as we worked out if Rancher Desktop would be useful for people, what features people want to use and what are good ways to build it. We are finally ready to answer that 1.0.0 question.

Log4j, the popular open-source logging library, had a rough December and closed out the year with an impressive streak of four critical vulnerabilities so far. Many are calling this the worst cybersecurity event in history. Again, so far.

Very recently, the JFrog security research team has disclosed an issue in the H2 database console which was issued a critical CVE – CVE-2021-42392. This issue has the same root cause as the infamous Log4Shell vulnerability in Apache Log4j (JNDI remote class loading). H2 is a very popular open-source Java SQL database offering a lightweight in-memory solution that doesn’t require data to be stored on disk.

DigitalOcean, or DO, brands itself as the “developer cloud,” and it’s no secret that it has a strong mind-share among developers, especially because of factors such as simple UI, performance, structured documentation, a robust community ecosystem, and last but not least, the affordable pricing. As developers started adopting microservices as the architecture of choice for their applications, DO responded quickly and launched their Managed Kubernetes offering, labeled DOKS.

If you’re like most organizations, you’re leveraging Jenkins for all sorts of things. Deployment pipelines, automated API tests, even glorified CRON jobs just to name a few.

Happy New Year 2022! The fireworks are all fired, the champagne is over. It is time to get back to work. We are glad to see you here though. 2021 was a good year for OpenStack and its Ubuntu-based community. First, we all have seen Ubuntu becoming the number one operating system (OS) for OpenStack deployment. Then, the Open Infrastructure Foundation (OIF) reported explosive growth in the number of production OpenStack clouds. The community grew and settled on the most convenient platform.

The previous blog post talked about the composability of applications. The key element for composing applications is defining the relations between application elements. And supporting relations is one of the advantages of the Charmed Operator Framework – including its runtime, the Charmed Operator Lifecycle Manager.
