Show HN: Pumbaa – A portfolio simulation tool for passive, index investments Hi HN, About a year ago I wrote a few scripts and spreadsheets to calculate the historical performance of various passive investment portfolios. There is portfoliovisualizer.com but if you are not from the US it's less relevant because everything is calculated with respect to the US dollar, and you cannot combine funds from other countries (say from the EU). In the past month I managed to turn it into a web app with the goal of giving individuals better tools for financial education. It allows you to build a portfolio composed of a few index funds (ETFs or mutual funds) and simulate its historical performance. It currently works with 7 currencies and includes funds from the US, EU, UK, Canada and Israel. Intentionally, only broad-market, passive index funds are included. If all of this doesn't mean much to you, you can visit the examples page to get a taste of some interesting portfolios. Here is an interesting example: For the past 22 years, US long-term treasuries had very similar returns to the S&P 500 (cherry-picked dates, but still interesting) [1]. On the technical side: The backend is a simple Flask app. A task runs once a day in the background to fetch the latest prices of ETFs and mutual funds from 20+ sources (central banks, stock exchanges). Frontend is Tailwind for CSS and a bit of native Javascript with d3. Everything runs on a $10/mo VPS. This is my first web app and there is still a lot of room for improvement so any feedback is welcome. Thanks in advance!

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,
