Open source has become so critical to so many aspects of our computing infrastructure. I recently stumbled across Ricardo Sueiras’ “AWS open source news and updates” posts. You may have heard of eBPF, the Linux technology that is reshaping Linux applications (and in some ways reshaping Linux itself).
