Show HN: Eleven – Code sandboxes with automatic HTTPS https://ift.tt/zgAv7QB

Show HN: Eleven – Code sandboxes with automatic HTTPS Eleven is the second project that I've built to learn Go. It lets you create code sandboxes in your cloud provider account easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it to deploy your app, as a remote development environment or even to test some code. It's up to you. For example, to deploy a Node.JS app on AWS: $ eleven aws init hello-world --runtimes node@18.7.0 --repositories eleven-sh/hello-world > Success! The sandbox "hello-world" was initialized. $ ssh eleven/hello-world forever node index.js > Forever: command started. Run "forever stop" in current path to stop. $ eleven aws serve hello-world 8000 --as hello.eleven.sh > Success! The port "8000" is now reachable at: https://hello.eleven.sh $ curl https://hello.eleven.sh > Hello World Still learning Go by the way, so I'm open to any suggestions to improve. https://ift.tt/OGMyRbW November 3, 2022 at 10:35PM

Open Source Authentication and Authorization https://ift.tt/DpR3st5

Open Source Authentication and Authorization I’m Rishabh and the co-founder and CTO at https://supertokens.com (YC S20). We offer open-source user authentication and we just released our user roles product for companies implementing authorization. Our users are web developers, and a prominent and adjacent pain point for our users is authorization. Developers typically implement two independent solutions for authentication and authorization. Offering AuthN and AuthZ in a single solution is something we’ve been thinking about for the last few years. Quick primer, authentication is knowing who the user is, and authorization is knowing what the user has access to. A physical analogy: A person enters a building. Authentication means reading their ID card and knowing that the person’s name is John. Authorization means knowing which floors, offices, and files John has access to. With increasing privacy and data complexity, companies like Netflix[1], Slack[2], and Airbnb[3] have built out their own complex authorization systems. To build our user roles product, we started with a first principles approach of covering authorization use cases using scripting languages such as XACML and OPA. But looking at existing solutions built by talented teams like Oso[4], Aserto[5], Cerbos[6], Strya[7], we realized that while these were powerful solutions, they were often overkill for most early to mid-stage companies (especially on the B2C side). We went back to the drawing board, reached out to our users and after dozens of conversations, we realized that most authorization needs require the ability to 1. Assign and manage roles and permissions 2. Store roles in the DB and session tokens to make it readable on the frontend and 3. Protect APIs and websites based on these roles and permissions. And so, we built user roles – a simple RBAC authorization service that focuses on the balance between simplicity and utility. It doesn’t cover many complex cases and we’re not looking to displace any of the authorization incumbents. But you can add AuthN and AuthZ using a single solution, quickly. In the near future, we’ll be launching an admin GUI where you can manage your users and their roles with a few clicks. We’d love for you to try it out and hear what additional functionality you’d like to see. What are your favorite authentication providers and what do they get right? - [1]: https://ift.tt/XFsRg96 - [2]: https://ift.tt/wLXQaAz - [3]: https://ift.tt/WjTC9eX - [4]: https://www.osohq.com/ - [5]: https://www.aserto.com/ - [6]: https://cerbos.dev/ - [7]: https://www.styra.com/ November 3, 2022 at 07:15PM

Show HN: I wrote an eBook on Linux CLI tools and Shell Scripting https://ift.tt/LjsMhub

Show HN: I wrote an eBook on Linux CLI tools and Shell Scripting Hello! This ebook aims to teach Linux command line tools and Shell Scripting for beginner to intermediate level users. The main focus is towards managing your files and performing text processing tasks. Includes plenty of examples, exercises (200+) and solutions. To celebrate my latest ebook release, you can download PDF/EPUB versions of Computing from the Command Line for FREE till 08-Nov-2022: https://ift.tt/WAyJauO (the web version linked as the post url is always free) All books bundle (all my 13 programming ebooks) is $10 (normal price $28) - https://ift.tt/sbDESke... Visit https://ift.tt/zN5uWYc for markdown source, example files, exercise solutions, sample chapters and other details related to the book. I would highly appreciate if you'd let me know how you felt about this book. It could be anything from a simple thank you, Gumroad rating, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors. Happy learning :) https://ift.tt/PCAFeUs November 3, 2022 at 04:41PM

Show HN: Nudges.fyi – simple, unmissable reminders via phone/text/email https://ift.tt/X7rVcum

Show HN: Nudges.fyi – simple, unmissable reminders via phone/text/email I built this app primarily for my wife, who has tried many mainstream todo-list apps (OmniFocus, Things, and Todoist come to mind) over the years with little success. She isn't particularly interested in setting up a productivity system and the administrivia that goes with it. Even having to remember to look at an app once a day was far from ideal for her. This app is an attempt at a solution for anyone that fits this description, with a focus on alerting over organization. Here's how it works: you create a nudge that's set to trigger at a given date and time, and the app phones you, texts you, or emails you (or all three) at the right moment. Nudges can trigger on a schedule, so something like "call me about monthly bills for the next month on the last day of every month" is quite easy to set up. It also works well (sample size 1, admittedly) as a supplement to a more robust GTD system. I use Things for almost everything, but my most important reminders are set up as nudges. I've worked on this on and off for the last month or so and I think it's ready for a Show HN. There's likely some rough edges in there so I wouldn't use it for anything _critical_ just yet (let me know if you see anything that looks buggy!). I cut a lot of scope in order to release an initial version quickly; here's a list of things I'm considering adding to the app in the near future: - Implement something analogous to Pagerduty: create nudges that repeatedly nag you (with something like an escalation policy) until you acknowledge them - More notification channels: get nudges on Telegram, WhatsApp, Slack, etc. - Families (or teams, possibly) share a namespace and can send nudges to each other - Nudges that collect a response: possibly for polls, a daily diary entry, or habit tracker - Incoming and outgoing webhooks - Snooze a nudge so it re-triggers in X minutes I work on distributed systems at my day job and haven't done frontend and CRUD things in a long while now, so building this out was a nice change of pace. If anyone's curious, the app is built with: Next.js (in static HTML mode) and Tailwind for the frontend, Go for the API server and background nudge loop, and SQLite (+Litestream) for persistence. In any case, I'm looking for feedback from the HN community here: is this something you would use? TL;DR: schedule reminders for yourself via phone call, text message, and/or email (PS: the free plan doesn't allow call/SMS nudges because I'm a bit wary of spam, but if you'd like to give this a shot and can't [or don't want to] subscribe to a paid plan at this point, send me an email at tim@nudges.fyi for a 1-month code) https://nudges.fyi November 2, 2022 at 10:30PM
