Show HN: I made a simple but powerful deployment tool Been using it for about a year now in production, but rewrote it completely in golang. My first go project so far. I wanted to have something that would make my life easier. A lot of tools nowaday kinda push you towards functional deployments and that usually doesn't work for me since I like stuff like LiveView by Phoenix and Websocket stuff in general. Old vercel deployments back when they allowed to deploy docker containers was a godsend, but since they don't offer that anymore I had to use services like fly.io(which is amazing) or heroku. However I wanted something selfhosted that I could just grab any VPS and use it, not being reliant on any one party for hosting, CI\CD, maintanence or anything really and so far it's going great. Hosting some small to medium sized projects using this little fella. Would be cool if yall would look at it and tell me what you think. Comments on my code also would be very welcome, go turned out to be very cool and I wanna try more stuff with it I was thinking to maybe use docker swarm to make it horizontally scalable, but it feels like such an overkill, wdyt? https://bit.ly/4bEo57F May 15, 2024 at 11:15PM

It received a tremendous amount of feedback and interest. And I was honestly overwhelmed by the response and then life happened. Over the past few weeks, I have been actively working on this project, trying to incorporate all the feedback and I’d love to share it with the world again. New features: 1. Filter problems by difficulty and category 2. Bookmark your favorite problems 3. Editor in the comment section supports markdown formatting 4. ...and some UI improvements throughout the website I am also starting a small telegram community of math nerds who would like to discuss all things math, as well as talk about upcoming features and feedback for the website. Here is the link - ( https://bit.ly/3V11bCc ) If you’d like to support my work through small donations, you can do it here - ( https://bit.ly/3UWDk6t ). Right now, teachyourselfmath runs for free. Later, I’d love to make features that people would love to pay for but fundamentally, the goal is to make math accessible through technology. There’s a lot of peer learning involved in the comments section of these math problems. All of this gives me more reason to keep working on this.

Show HN: How to Install Python on a Mac https://bit.ly/44FawCK

Show HN: How to Install Python on a Mac I recently began using Python for AI projects and found Rye, which is an all-in-one tool that replaces Pyenv, Pip, and Venv, for a more project-centered approach to Python development (like Ruby or JavaScript or Rust). As someone who habitually writes tutorials for beginners, I wrote a series of articles for my mac.install.guide site advocating setting up Python projects using Rye. Am I leading beginners down the wrong path by suggesting Rye for Python tooling? Beginners often encounter READMEs and tutorials that show `pip install something` as a first step. That led me to the error "Command not found: pip" [0] (so I wrote about that). Solving that led to the error "Command not found: python" [1] and I first tried the system Python installed with XCode Command Line Tools and then "brew install python" [2]. That led me to "Error: externally-managed-environment" [3] which is a recent safeguard to encourage Python users to use environment managers to avoid dependency conflicts from globally-installed packages. At that point, I realized that there are two different use cases for using Python, either standalone tools and applications, where it's best to "install Pipx" [4], or programming with Python, including installing Python packages, where there's need for a version manager, a package manager, and an environment manager. There's no built-in version manager (for that, you will "install pyenv" [5]) but Pip and Venv are a built-in package manager and environment manager, once you have Python installed. As a guide, I wrote about "Mac Python" [6] and how to "Update Python" [7]. This diagram [8] helped me understand which Python tools are used for version management, package management, and environment management. That's where I found Rye, an all-in-one tool that eliminates the need for Pyenv, Pip, Venv, and other tools. So I wrote about how to "install Python with Rye" [9] and how to "Use Rye" [10]. These are the articles that were most helpful in showing how to set up a Python development environment: - https://bit.ly/44Fax9M... - https://bit.ly/44FaxGO... - https://bit.ly/44CHh3D... For beginners, I feel Rye is a better choice (as a single tool) than a grab bag of multiple tools, but I heard there is some resistance to Rye in the Python community, as it's written in Rust and other people have already tried to improve the Python developer experience without achieving success. Others have suggested asdf or mise (good choices for managing multiple languages), Docker (appropriate for collaboration on a complex project but overkill for simple, one-developer projects), and Nix (a lot to learn). To wrap it all up, I wrote a freeCodeCamp article, "How to Install Python on a Mac" [11]. I'm sharing the links here for comments and feedback from those more experienced than I.

Show HN: CarCheck – Car Buying Checklist App Hey HN! A few years ago my brother in-law was looking to purchase his first car. He was struggling to know what to look for when going to car dealerships and felt quite overwhelmed with the financial and practical decisions required. Not that I have any particular expertise with cars or the engineering involved, but through my own experiences purchasing cars and owning them I gave him some advice and "tips". As anyone would. Things only morphed from there, I spent the next couple of years in my spare time learning to code, researching, and developing CarCheck. It's been a journey! Hindsight is 20/20 and some things I would have done differently, but that's part of the fun. I am proud to be sharing my (imperfect) first app with the world and excited to learn from you all for my next project :) I would love to hear your feedback! https://bit.ly/3WBgX7S May 13, 2024 at 03:56AM

Show HN: Open-Source Video Editor Web App https://bit.ly/4bqXGdK

Show HN: Open-Source Video Editor Web App Hey everyone, for the past like six months I've been working on a portfolio project. I got tired of doing easy projects, so I decided to tackle something bigger and more challenging. That's when I came up with the idea of a video editor. This piece of work is intended to showcase my skills and land me a job, but I like to think when working on projects that my idea is so cool that people will like to use it, and I treat every project like a startup idea. Also I havent seen many open source video editors especially on web so that was one of the points why I decided to make that and not something else, but in the end its learning experience and im not expecting much if at all. A bit about the video editor itself: -website: https://bit.ly/4bbBnJe -its free -its open source (MIT Licensed) -its using Webcodecs API for quick rendering -works fully inside browser, client side, no private data is kept -I made some readme with more details, im not expecting contributions but I added bit about it: https://bit.ly/3UUkOM5 Features: -Trimming -Splitting -Supports - Text, Audio, Video (mp4) and Images -Clip editing on preview - rotating, resizing, text styling and more -Undo/Redo -Render in different resolutions, up to 4k. Things to know before using this editor: -it is simple editor, but its my main project im working on and improving it. -right now it only works with videos 25 fps and more but not less -only 4 tracks -- its something I could improve quickly but forgot -bug here and there (eg. filmstrip not rendering until timeline scroll moved) -its not working on phones yet (drag and drop API problems) I'd love to hear your thoughts and feedback on it.

The rationale behind it is while wireguard is a fantastic protocol cryptographically it leaves a lot to be desired when it comes to enrollment and end user device security. Obviously instead of using an off the shelf solution like tailscale, I decided to reinvent the wheel which has honestly been quite fun with learning about eBPF, and recently clustering and HA with etcd! The most recent version (in the docker container) contains about 6 months of very new work bringing it all from sqlite3 to etcd. So please be forgiving if it does some weird things! Hope you all enjoy! P.s Im not a web developer and any tips on that front to make it less teeth pullingly awful are welcome! https://bit.ly/3yd1rVN May 11, 2024 at 08:31AM

Show HN: MinimalChat – A Simple and Customizable LLM Chat Application Hello everyone! I have a hobby project that has become fairly full featured that I figured I would share. The idea of MinimalChat has been to create a project that is a lightweight and dead simple application that can be deployed locally in a few seconds (with docker). While of course also having most of the nice to have features and looking pretty nice. A nice bonus is it a Progressive Web Application so it can be installed like a normal application to your mobile device. It has a full mobile UI. For those using Chrome and Edge you can also locally download, load and host entirely via your browser models like LLama-3-8b with hardware acceleration via WebGPU. It's pretty experimental but it does work! I won't bloat this post reiterating it's features, the GitHub Readme gives a good idea of the application abilities.

Show HN: Qualitician – Software Testing Job Board Hi HN! I'm really excited to share this project with the Hacker News community and would love to hear your valuable feedback/suggestions. Qualitician is a platform for job seekers to find software testing jobs and for businesses to find and hire software testing talent. Few Reasons to create this, 1. I’m a software tester by profession and at some point of time during my career, I had to visit multiple general job boards for software testing jobs. 2. There’s never been a dedicated career portal for job seekers and employers in the software testing domain. 3. Bright Outlook occupations (Software Quality Assurance Analysts and Testers) are expected to grow rapidly in the next several years, will have large numbers of job openings. 4. The demand for skilled software testing professionals is growing rapidly as more organizations adopt quality engineering practices and integrate software testing into every stage of the SDLC. 5. Reports suggest that most IT companies spend about a quarter(25%) of their QA budget on software QA staffing. We made it available to users in India first and we are planning to release it to other country users asap. Please check it out and let me know what you think! Thanks! https://bit.ly/3WA3Ljw May 10, 2024 at 03:36PM

Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years https://bit.ly/3UWxDFP

Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://bit.ly/3JUjZfR It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer wasn't sure if I meant that it returned an error or if it was unresponsive. So the engineer would be frustrated, I would be frustrated, and fixing stuff would slow to a halt while we went back and forth to clarify how to repro the issue over async Jira comments. It’s actually pretty crazy that while so much has changed in how we develop software (heck, we have types in javascript now*), the way we capture and report bugs is just as manual and lossy as it was in the 1990’s. We can run assembly in the browser but there’s still no tooling to help a non-engineer show a bug to an engineer productively. So that’s what Jam is. Dev tools + video in a link. It’s like a shareable HAR file synced to a video recording of the session. And besides video, you can use it to share an instant replay of a bug that just happened — basically a 30 second playback of the DOM as a video. We’ve spent a lot of time adding in a ton of niceties, like Jam writes automatic repro steps for you, and Jam’s dev tools use the same keyboard shortcuts you’re used to in Chrome dev tools, and our team’s personal favorite: Jam parses GraphQL responses and pulls out mutation names and errors (which is important because GraphQL uses one endpoint for all requests and always returns a 200, meaning you usually have to sift through every GraphQL request when debugging to find the one you’re looking for) We’re now 2 years in to the product being live and people have used Jam to fix more than 2 million bugs - which makes me so happy - but there’s still a ton to do. I wanted to open up for discussion here and get your feedback and opinions how can we make it even more valuable for you debugging? The worst part of the engineering job is debugging and not even being able to repro the issue, it’s not even really engineering, it’s just a communication gap, one that we should be able to solve with tools. So yeah excited to get your feedback and hear your thoughts how we can make debugging just a little less frustrating. (Jam is free to use forever — there is a paid tier for features real companies would need, but we’re keeping a large free plan forever. We learned to build products at Cloudflare and free tier is in our ethos, both my co-founder and I and about half the team is ex-Cloudflare) and what we loved there is how much great feedback we’d get because the product was mostly free to use. We definitely want to keep that going at Jam.) By the way, we’re hiring engineers and if this is a problem that excites you, we’d love to chat: jam.dev/careers May 10, 2024 at 02:08PM

Show HN: Tegon: AI-first open source alternative to Jira and Linear Hi HN, this is Harshith from Tegon ( https://bit.ly/3UzQLYF ) an open-source issue-tracker that uses AI to automate manual tasks and workflows, and to provide context to engineers for a given task. Here is a demo video: ( https://bit.ly/4bwCqmS?... ) As engineers we hated Jira, it is slow and too complicated and enables a lot of processes and micro-management which used to kill our productivity. What makes Tegon faster: We load all the data from local (indexed db), making it super fast to load and navigate. We make this happen by doing a real-time sync in the background. Then we use AI to automatically create a title from the description, so you don't have to spend time figuring out a title. We then suggest labels, assignees and duplicate issues when you are creating a new issue Then we have a "Command Center" of agents: 1. Code Review Agent reviews linked pull requests for new tasks, ensuring code quality by preventing the incorporation of suboptimal code. 2. Bug Agent, upon bug assignment, will attempt to reproduce the bug, propose solutions, and in some cases, even implement these solutions in a new PR. 3. Task Prioritisation Agent assists team leaders in managing the sprint by doing real-time assessments of the tasks, priority, and bandwidth and suggesting changes to be made. We got started on this a few months ago with lots more to come. We’re eager to get feedback and keep building, so please let us know what you think! https://bit.ly/4ae9uir May 7, 2024 at 08:52PM

Show HN: SimBricks – Modular Full-System Simulation for HW-SW Systems https://bit.ly/3URESi3

Show HN: SimBricks – Modular Full-System Simulation for HW-SW Systems Hi HN, we are building SimBricks, an open-source simulation framework for heterogeneous systems, especially with custom hardware. SimBricks modularly combines existing simulators for machines, networks, and hardware, allowing you to build, test, and evaluate intricate complete systems in a virtual environment. Head over to the SimBricks website ( https://bit.ly/3wq6ly4 , also has a quick demo video) to learn more. We have pre-built docker images, and you can even immediately play around on codespaces. Concrete use-cases: - Evaluate HW accelerators, from early design with simple behavioral models, to simulating complete Verilog implementations, both as part of complete systems with many instances of the accelerator and machines running full OS and real applications (we did a university course on this with SimBricks). - Test network protocols, topologies, and communication stacks for real workloads in potentially large systems (we ran up to 1000 hosts so far). - Rapid RTL prototyping for FPGAs, no waiting for synthesis or fiddling with timing initially (we simulate the complete unmodified RTL for the Corundum Open-source NIC with their unmodified PCIe drivers). SimBricks originally started out as an internal research tool, for helping us build and evaluate our research ideas on network protocol offload, but has since grown into a separate open-source project. Would be great if you give it a shot and let us know what you think! https://bit.ly/3wq6ly4 May 8, 2024 at 11:22PM

Show HN: I built a Notion for science https://bit.ly/3woNOC8

Show HN: I built a Notion for science I struggle with handwritten notes, but it's always been the primary way to write scientific notes. To do scientific writing on existing keyboard-and-mouse tools generally requires either significant knowledge of the software, the use of screenshotting/exporting from external tools, or (often) both. That's why I made Stempad, which is meant to rival the speed of pen-and-paper for scientific writing. I've currently added 7 different scientific blocks (and several basic blocks too) and plan to continuously add more. Questions are welcome, and preliminary feedback or constructive criticism is really appreciated!

Show HN: I built a random dilemma generator https://bit.ly/44tjjrf

Show HN: I built a random dilemma generator Last week my 9 year old son walked up to me and asked "Would your rather shit your pants in public or drink spoiled milk?", and I was intrigued. Turns out he did not make this up himself, but got the dilemma from a card game. A couple of nights ago I decided to digitize some of these cards and create a simple open source app for it. Just a little fun project; no monetization or bigger goal, really. Link: https://bit.ly/4dp923B Tech stack: - Back-end: Laravel - Front-end: Plain HTML and Tailwind with a sprinkle of Alpine.js - Deployment: Laravel Forge, linked to a Hetzner VPS. Deployment triggers whenever I merge to main. The app itself is super simple. Just a bunch of markdown files and a controller that picks two random files ¯\_(ツ)_/¯ https://bit.ly/4dp923B May 5, 2024 at 09:04PM

Show HN: I built a website to share files and messages without any server https://bit.ly/4bqH0mC

Show HN: I built a website to share files and messages without any server NeighborHoodShare: It is a p2p files and messages sharing platform without involvement of any server. It has end-to-end encryption, ensuring your messages and files remain confidential. These are some features: - Share photos, documents, videos, and more with ease, no matter the size. - Connect instantly with anyone for speedy and reliable file transfers, bypassing the need for centralized servers. - Get started in minutes with our intuitive interface designed for seamless communication. No registration. - Easily connect with others using QR codes, simplifying the sharing process further. The inspiration behind NeighborHoodShare stemmed from a common dilemma: the reluctance to share personal contact details like phone numbers or email addresses when sharing photos or messages with strangers. With NeighborHoodShare, you can share content securely without compromising your privacy. I would be happy to hear your feedback and suggestions for improving NeighborHoodShare. I had written a blog on how p2p networking in browsers work: https://bit.ly/3wt0yHS... https://bit.ly/3JSisXy May 5, 2024 at 08:42AM

Show HN: Panza: A personal email assistant, trained and running on-device Tired of crafting well-polished emails and wish you had an assistant to take over the hard work while mimicking your writing style? Introducing Panza, a personalized LLM email assistant that runs entirely on your device! Choose between Llama-3 or Mistral, tailor it to your unique style, and let it write the emails for you. Take a look at our demo and give it a try on your emails at: https://bit.ly/3Qp7IUA Some technical details about Panza: - Panza is an automated email assistant customized to your writing style and past email history. - Panza produces a fine-tuned LLM that matches your writing style, pairing it with a Retrieval-Augmented Generation (RAG) component which helps it produce relevant emails. - Panza *can be trained and run entirely locally*. Currently, it requires a single GPU with 16-24 GiB of memory, but we also plan to release a CPU-only version. - Training and execution are also quick - for a dataset on the order of 1000 emails, training Panza takes well under an hour, and generating a new email takes a few seconds at most. https://bit.ly/3Qp7IUA May 2, 2024 at 10:27PM

Show HN: I made ComfyUI nodes for virtual try-on using IDM-VTON https://bit.ly/3UmWWiK

Show HN: I made ComfyUI nodes for virtual try-on using IDM-VTON Hey HN, 4 days ago I went through the impressive demo of IDM-VTON on HuggingFace. I found there was no ComfyUI adaptation of this new model. So I’ve implemented custom nodes in ComfyUI that allow anyone to perform virtual try-ons using IDM-VTON. Simply load an image of a model and a garment, and the node will generate a new image with the garment worn by the model. I would love to hear your thoughts and feedback!
