  An eBook with hundreds of GNU Awk one-liners2020 · ▲539

  Hi, I recently published my ebook on GNU awk one-liners [1]. It starts from the basics of awk syntax and then discusses one-liner examples. There's a chapter on regular expressions as well. The github repo has the details on how to get the PDF version, all the example files and code snippets used in the book, sample chapters as well the markdown source used to generate the PDF. I made all my ebooks [2] free last month amidst the pandemic fears. These include GNU grep & ripgrep, GNU sed and three books on regular expressions (Python, Ruby, JavaScript). I'd appreciate your feedback and hope…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
