Go for DevOps

Experienced developer report about the features of Go
18 August 2017   2715

Go is an great open source multiplatform language for cross-platform development which is ideal for ops tools. If you target multi-platform, multi-architecture environments, come learn how Go enables you to write once and run anywhere. No more need for kludgy shell scripts.

This talk will cover the built in features of Golang that make it possible to write your code on one platform and seamlessly deliver it to many different operating systems and architectures. As a devops engineer I have tools and services that need to support multiple operating systems running on different CPU architectures.

You will learn the specific ways to generate *bsd-386 binaries on Windows-x64, android-arm binaries on Linux-ppc and all combinations in between. I'll also be covering coding techniques to keep this manageable and libraries that support you in things like file system navigation.

CockroachDB to Change License Type

The only restriction in new bundle of licenses is the ban on selling commercial versions of CockroachDB, made in the form of cloud services

The developers of the distributed DBMS CockroachDB have announced the migration of the project source code into a bundle from the Business Source License (BSL) and Cockroach Community License (CCL), which is not free due to the discrimination of certain categories of users. The BSL license was proposed by MySQL co-founders three years ago as an alternative to the Open Core model. The essence of BSL is that the extended functionality code is initially available for making changes, but for a certain period of time it can be used for free only if the additional conditions are met that require a commercial license to be circumvented.

The new license allows the use of CockroachDB on any number of nodes in the cluster and embedding in applications, including those that are sold to customers or run as services. The only restriction that prevents the license from being considered free and open is the ban on selling commercial versions of CockroachDB, made in the form of cloud services. To issue a CockroachDB in the form of paid cloud services now requires the purchase of a commercial license.

As in the case of the re-licensing of MongoDB, Redis and TimescaleDB modules, the reason for the transition to a non-free license is the fight against the parasitization of cloud service providers who create derivative commercial products and resell open DBMS as cloud services but do not participate in the community and do not help in developing. It happens when the cloud providers, who are not related to the project, resell ready-made open solutions and benefit, but the developers are left with nothing.
