For that reason, it's often the answer to the question, "How do I do math in the Linux shell?" This style of response is common online: read more

The meteoric rise of containerization and microservices has been necessary to meet the growing demand for applications, but getting it right means overcoming some critical network orchestration challenges. Out of the complexities that developers of cloud-native applications face, strategically utilizing Kubernetes ingress controllers is among the most difficult components to understand—and among the most important.

Toolboxes started life often described as disposable containers – and that is still one of their major uses: install stuff, then try it out in the relative safety of a container, and lastly, cleanly dispose of it.

Lots of love for AMD and POWER 10 and a hint of some Google's operational code making it into future releases Linus Torvalds has released a new version of the Linux kernel.…

Natural language processing (NLP) is a specialized field for analysis and generation of human languages. Human languages, rightly called natural language, are highly context-sensitive and often ambiguous in order to produce a distinct meaning. (Remember the joke where the wife asks the husband to "get a carton of milk and if they have eggs, get six," so he gets six cartons of milk because they had eggs.) NLP provides the ability to comprehend natural language input and produce natural language output appropriately. read more
