Show HN: I build djit.su during the coronavirus lockdowns – a new code editor https://ift.tt/3cfLZHK

Show HN: I build djit.su during the coronavirus lockdowns – a new code editor TL;DR: During the coronavirus lockdowns I built a new kind of code editor - a notebook-like development environment inspired by the awesome teachings of Bret Victor. Check it out: https://djit.su Quick backstory: I've always wanted to create a different kind of code editor that encompasses several aspects of what I consider programming. I think it's started somewhere around the time Bret Victor had his famous talk - it blew my mind, seeing how he develops the game in real-time modifying variable and functions as he goes. About three months ago, as the corona lockdowns hit, the company I just recently started working at collapsed due to lack of funding. I started working on a thing . It began when I finished with my ObservableHQ Coronavirus Stats (https://ift.tt/2XD6UyU) and wanted to extend the table with more features. Today I finally shipped what I consider truly first functional version of djit.su — a rudimentary yet-to-be-fully-defined tool that I designed in my mind for almost a decade, prototyped at least four different times in the last five years, and finally get to play with for the first time after building it for the past 3 months. I've created a quick reference example for how to update the cell value from the react component - check it out here: https://ift.tt/2yLWowX — it might serve you as a good point to get an idea how to interact with djit.su as the documentation is non-existing at this point. Any and all comments, suggestions, and recommendations are welcome. May 30, 2020 at 10:02PM

Show HN: SSH tunneling course for devs, sys admins, and infosec professionals https://ift.tt/3gEcbis

Show HN: SSH tunneling course for devs, sys admins, and infosec professionals A little over a year ago I gave away over 4,600 copies of my intro to SSH tunneling book, The Cyber Plumber's Handbook, for free over a 48 hour period to the awesome folks here on Hacker News [0]. Since then, I've been getting a lot of feedback about creating an interactive lab where SSH tunneling and port redirection techniques can be practiced in real scenarios. With a bit more time during the quarantine, I finally found the time to launch the lab portion. For the HN family, I'm offering the book and 2 weeks of lab time for 50% off ($19.99) with this Gumroad link through June 6: https://ift.tt/3gEe5Qk Why learn SSH tunneling? SSH tunneling is a skill you can use for the rest of your IT career. SSH tunneling and port redirection are skills that can be applied in any information technology discipline, so it does not matter if you are a network engineer, red teamer, penetration tester, developer or something in between. That being said, the examples tend to skew towards pairing tunneling techniques with penetration testing tools (including Metasploit). Lab Overview Four jump boxes provide the Internet facing portion of the lab. However, the fun really starts when you start leveraging tunneling techniques to reach the internal side of the network to access services such as Secure SHell (SSH), Web, and Remote Desktop Protocol (RDP). The Linux and Windows targets are also running vulnerable services that can be exploited for the true tunneling ninjas. Each of the exercises has a brief description and solution to assist you in the event you get stuck. [0] https://ift.tt/2y2jX0F May 30, 2020 at 03:35PM

Show HN: Top 10 Newest HackerNews Stories (Phoenix/LiveView) https://ift.tt/3ciyEy4

Show HN: Top 10 Newest HackerNews Stories (Phoenix/LiveView) HNLive is a small Elixir/Phoenix/LiveView web app showing the top 10 (by score or number of comments) newest HackerNews stories in "real time" (i.e. as quickly as updates become available via the HackerNews API). You should find the app running on https://ift.tt/2Xeks58 - please note that this is running on the free tier with limited memory and resources. GitHub: https://ift.tt/3gEdU7C The motivation for building HNLive was twofold: 1. I had read and heard many good things about Elixir, Phoenix and LiveView, and after watching Chris McCord`s demo "Build a real-time Twitter clone in 15 minutes with LiveView and Phoenix 1.5" on YouTube, I finally said to myself: "That looks awesome, time to learn Elixir and Phoenix!" HNLive is the app I built over the last couple of days while on this learning journey. 2. I love browsing HackerNews, but for me the selection of stories on the front page, the "newest" page and the "best" page is not ideal if I want to see at a glance which new stories (say, submitted over the course of the last 12 hours) have received the most upvotes or are discussed particularly controversially (as judged by the number of comments). HNLive attempts to address this using data from the HackerNews API to provide the top 10 submissions, sorted by score or number of comments, taking into account only the last 500 submissions. I also wanted to see updates to the top 10 (and scores and number of comments) in real time, which was made easy by using LiveView. May 30, 2020 at 03:03PM
