Show HN: Slotmachine, to book and free server ports at scale https://ift.tt/ZhCrDmY

Show HN: Slotmachine, to book and free server ports at scale This is a very specialized Go library and, frankly, somewhat of a straw man: I've found myself needing to quickly assign ports on servers with a high density of highly ephemeral inbound/outbound connections where the protocol relies on a specific port number. Obviously, running sequentially through a list of ports until I find one I have not already allocated does not perform very well. I was surprised when I did not find anything already addressing this need. So, this is the straw man part: surely I missed it! Anyway, should you ever need something like that... here it is. https://ift.tt/Ab87ZIU September 11, 2023 at 11:39AM

Show HN: Interactive exercises for GNU grep, sed and awk https://ift.tt/OxeFwah

Show HN: Interactive exercises for GNU grep, sed and awk Hello! For the past few months, I've been using a Python framework called Textual to create TUI apps for interactive exercises. Released the app for GNU awk earlier today, so thought I'd create a post here. If you already know how to manage Python packages, you can use the following command to get all the three apps: pip install grepexercises sedexercises awkexercises `pipx` should also work, but I haven't tested it. The GitHub repo has the source code as well as more detailed installation instructions. You can use alternative CLI tools to solve these exercises as well. For example, Perl instead of GNU awk or ripgrep instead of GNU grep and so on. Hope you find these TUI apps useful. I'd highly appreciate your feedback. Happy learning :) https://ift.tt/Hp9kFEi August 17, 2023 at 05:13PM

Show HN: My Book Bulletproof TLS and PKI (Second Edition) Is Out https://ift.tt/5PZ9mxF

Show HN: My Book Bulletproof TLS and PKI (Second Edition) Is Out Hello HN. I am excited to share with you my new book, Bulletproof TLS and PKI. I've worked in this space since the very early days (think SSLv2), always frustrated with the fact that the field is vast but the documentation poor. That first led me to create SSL Labs (which ended up being very popular) and then the first edition of my book (in 2014), where I aimed to cover everything a curious person needed to know about SSL/TLS and PKI. Most importantly, it's a very practical book that you can use to just learn what you need at that moment. The second edition (just out) adds coverage of TLS 1.3. I publish two chapters as a separate (and free) OpenSSL Cookbook. There's another free sample chapter as well. The best part of Bulletproof TLS and PKI is that it's a living book. There's nothing worse than obsolete documentation! Because none of the traditional publishers were interested in that sort of thing,
