Show HN: I'm 17 and built a startup to find or sell parking spots Hey HN! I'm Dris, I'm 17, and for the past few months, I've been solo-developing Parkt, an app that lets you quickly reserve or sell parking spots. Parking sucks - it's expensive, hard to find, and you usually overpay or get a ticket. With Parkt, you can reserve parking in 2 taps, or list your unused space in under 5 minutes. It's now free to download on iOS (with Android coming soon)! You can also check out a demo on the site if you're interested. If you know someone who might use Parkt, sharing the app would be super helpful! Feedback is also appreciated. https://parkt.app/ September 1, 2024 at 12:23AM

Show HN: Website with coding puzzles from job interviews https://ift.tt/BXxgpe0

Show HN: Website with coding puzzles from job interviews Hi Friends! As I run another site with more general programming exercises for years - I always felt they are different from puzzles and test projects proposed at job interviews. So recently I started this new place and am slowly adding problems here. Of course the number of such challenges I encountered in interviews myself is quite limited. So if you may recollect something of the kind which could be converted to a puzzle - please, kindly share it to me (e.g. with "rodiongork" at gmail). Puzzles of algorithmic nature or system-oriented and language-specific - are all welcome. Currently I'm working to add a few postgresql exercises and executor for them. https://ca4pro.com August 30, 2024 at 07:57PM

Show HN: Repo2vec – an open-source library for chatting with any codebase https://ift.tt/vXb7uia

Show HN: Repo2vec – an open-source library for chatting with any codebase Hi HN, We're excited to share repo2vec: a simple-to-use, modular library enabling you to chat with any public or private codebase. It's like Github Copilot but with the most up-to-date information about your repo. We made this because sometimes you just want to learn how a codebase works and how to integrate it, without spending hours sifting through the code itself. We tried to make it dead-simple to use. With two scripts, you can index and get a functional interface for your repo. Every generated response shows where in the code the context for the answer was pulled from. We also made it plug-and-play where every component from the embeddings, to the vector store, to the LLM is completely customizable. If you want to see a hosted version of the chat interface with its features, here's a link: https://www.youtube.com/watch?v=CNVzmqRXUCA We would love your feedback! - Mihail and Julia https://ift.tt/xE6roUC August 29, 2024 at 01:29AM

Show HN: Warehouse OpenAI requests to your own database https://ift.tt/S3FRspE

Show HN: Warehouse OpenAI requests to your own database Today we’re launching Velvet, an AI gateway for warehousing OpenAI and Anthropic requests to your PostgreSQL instance. We originally built an AI SQL editor, but realized that customers were using it to monitor their AI requests in production. We had already built an AI request warehousing tool internally to debug our SQL editor and gave some customers access. A few days into testing this idea, our pilot customer launched [1] and we began warehousing 1,500 requests per second. We worked closely with their engineering team in the following weeks, completely re-architecting Velvet for scale and additional features (such as Batch support). Along the way, other companies began seeking out Velvet to get visibility into their own LLM requests. We’re launching our AI gateway as a self-serve product today, but our pilot customers are already warehousing over 3 million requests per week - so the system is stable and performant. What makes Velvet unique is that you own the data in your own database. Also, we’re the first proxy that gives visibility into OpenAI batch calls - so you can observe and monitor async calls that save you money. Some technical notes: - Supports OpenAI and Anthropic endpoints - Data is formatted as JSON and logged to your own PostgreSQL instance (can add support for other databases for paying customers). - You can include queryable metadata in the header, such as user ID, org ID, model ID, and version ID. - Built on Cloudflare workers, which keeps latency minimal (using our caching feature will reduce latency overall) - Built for security + starting process of SOC II soon Why warehouse your requests? - Understand where money is spent. Use custom headers to calculate the cost per customer, model, or service. - Download real request/response data, so you can evaluate new models (e.g., re-running requests with a cheaper mini model) - Monitor time to completion of batch jobs. (e.g., OpenAI says 24 hours, but our customers average 3-4 hours) - Export a subset of example requests for fine-tuning It’s just a 2 line code change to get started. Try a sandbox demoing the logging proxy here: https://ift.tt/mN1pGkS More details in our docs https://ift.tt/PDt4NxT [1] https://ift.tt/utaX7wQ https://ift.tt/EzC9tg3 August 28, 2024 at 10:21PM

Someone suggested adapting the DSL to play Dungeons and Dragons. So, here we are! What is it? An AI-powered, voice-controlled D&D adventure set in the world of Dvorak. Talk to characters, explore locations, and shape the story using your words. Use your microphone to interact with the AI dungeon master. Explore freely – interrupt, ask questions, or take unexpected actions. If you make friends at the tavern, you can also just hang out there and chat. Hint: Talk to the bartender to move the story along. This is an early demo, and I'm eager for your thoughts: Is the concept engaging? What works well, and what doesn't? I've added a feedback form to the webpage in case you want to drop a comment without posting on HN. Thanks for trying out the demo! https://pocket.computer August 23, 2024 at 06:51PM

Show HN: High school robotics code/CAD/design binder release Hello HN! My name is Patrick, and I am a junior at my High School’s FRC robotics team FRC 341 “Miss Daisy” (yes named after the movie). Every year, during the first weekend in January, a new robotics game is released (no it’s not battlebots). The game could be about launching balls into a goal, climbing monkeybars, or placing cubes on a see-saw. This year we were challenged to build a robot that could shoot orange foam donuts into a goal about 6 feet in the air. Here is a yt video with the game animation https://www.youtube.com/watch?v=9keeDyFxzY4&t . After we received the game we then had six weeks to design, build, program, and field a robot capable of playing the game. And we did pretty well this year! I have attached a ChiefDelphi thread (robotics forum) where we have released our season materials. This being our CAD (3D model of robot), code, and design binder. I encourage you to take a look and leave any questions that you may have. Thanks a lot! https://ift.tt/8eGbHSO August 25, 2024 at 01:10AM

Show HN: Support.dev – a non-trivial Vue and Supabase app I built this tool about a year ago to get really good at the supabase ecosystem. We were trying to raise money on the idea, but that didn't occur, so I wanted to open-source it, as I would love to give back to the commmunity. It allows you to invite friends and family to be helpers for child-care, meals, and transportation, and then you can create an event and they will get auto-invited to it and can choose to support you. It is using vue on the frontend and then supabase on the backend for auth, database, realtime, storage, and edge functions. Anyway, I hope someone finds it useful, there are some pretty cool features with db triggers in the database calling out to edge functions to process data, and then realtime notifications for invites and such. https://ift.tt/DG1YLoh August 23, 2024 at 11:29PM

Show HN: We're developing AI employees – seeking early adopters and feedback Hi HN, We're a small team(actually only myself working on this topic) working on an AI employee system that aims to revolutionize how teams work. Our goal is to create AI assistants capable of handling tasks like coding, project management, and documentation. The product is still in development (expected beta in 3-6 months), but we're looking for early adopters and feedback to shape its direction. Some key points: 1. 24/7 AI assistants for various roles (developers, managers, etc.) 2. Leveraging our in house low-code platforms LCDP.ai, RAG (Retrieval-Augmented Generation), and Large Language Models to create adaptable and efficient AI employees 3. Aiming for a 100% boost in team efficiency 4. Currently in active development, seeking input on feature prioritization We're offering early adopters a lifetime 50% discount for a $19.9 reservation fee. We know it's early, but we believe in building in public and involving potential users from the start. What we're looking for: 1. Would you use AI employees in your workflow? Why or why not? 2. What features would make this invaluable for your team? 3. Any concerns about integrating AI so deeply into work processes? We're here to answer questions and discuss the future of AI in the workplace. Looking forward to your thoughts!

Show HN: an AI copilot for Next.js developers https://ift.tt/IAQJlre

Show HN: an AI copilot for Next.js developers Hey HN! I'm Andrew, one of the creators of Glass, a copilot for Next.js and React developers. Glass appears as a chat bar on your locally running Next.js server, and you can tell it to make changes like "build a dashboard" or "add a login button". Glass makes the changes to your sourcecode in real-time. Our goal with Glass is to automate away the easy but slow parts of frontend development, like locating the right file to edit, writing tailwind by trial-and-error, and copy-pasting boilerplate from Claude and other tools. We want to let you do all the tedious work entirely from your browser. We built Glass using a VS Code extension that handles communications with an LLM (4o) and reads/writes to your codebase. We also built an SWC plugin to map where clicked in your browser to a location in your sourcecode - this was interesting because we determine which component you clicked on and where its instance is located in your codebase, so we did a lot of interesting prop injections to make this work. Lastly, we render our UI directly on your project using a React Provider - this was mainly to avoid building yet another interface you have to install (although it has its downsides, like disappearing when there's an error). We're super excited to build the tool out more, but we wanted to get a sense of what you think! The jump-to-code and hover-component features have been the most helpful for me developing projects in general, and the AI part can help with easier tasks like rearranging a component and doing annoying tailwind work. You can install Glass on your Next.js project here: https://useglass.ai/ . Everything is free for now, and we'd love to hear your feedback. https://useglass.ai August 17, 2024 at 05:46AM

Show HN: Shadcn/pro – Advanced Next 15 and React 19 SaaS starter kit Hey HN, Hope you are doing well! As a fellow founder, I've got something that could save you 2-5 months of development time. I'm excited to share shadcn/pro, a SaaS starter kit for building modern web apps. It’s built with Next.js 15, React 19, Auth.js (next-auth v5) and shadcn/ui. The primary focus is on the core aspects of the web application, including authentication, billing, onboarding, organization management, member invites, profile management, email integration, dashboards, master/detail pages, API keys, webhooks and more. As you probably noticed Next/React/Auth.js is currently stuck in an upgrade limbo. There are major changes in Next 15 regarding caching and new action hooks in React 19. Furthermore Auth.js got rewritten to fit the app router model. What if you could use the latest versions, but make it some else's problem (me). I'm committed to keeping all dependencies up-to-date and adding features you need but don't have time to build while you can focus on your product domain. The application is well-designed, fully responsive and built using server actions and React Server Components (RSC). Some of the libraries used are - next-safe-action - nuqs - nice-modal-react - react-email - dnd kit - zod As for the auth you get - A FULL implementation of the credentials provider including everything necessary from OTP to password resets. - Google and Microsoft logins - Connected accounts - Session management The license is very business-friendly. Unlimited developers, projects, and commercial use. No strings attached. Website: https://shadcnpro.com/ Demo: https://ift.tt/gwkQiDr What's your biggest pain point in SaaS development right now?

Show HN: My Care Voice – We Help You Prepare for the What Ifs https://ift.tt/X9LWMlF

Show HN: My Care Voice – We Help You Prepare for the What Ifs We are excited to introduce My Care Voice to the HN community! It's been a personal quest of mine to develop a process to ease the burden of creating advance directives. Everyone needs them, but few think about it until it's too late. Typically, it requires an expensive visit to an attorney or the cumbersome, impersonal process of filling out paperwork. In 2016, my sister had a sudden heart attack in the middle of the afternoon. She was rushed to the hospital with no way to speak or respond. That was when I fully grasped the importance of having these wishes recorded and available. Her family, including her two kids in their early twenties, were in the hospital waiting room, not knowing her wishes during those terrifying moments. The doctors were completely in the dark about how far to go with life-sustaining measures.

Show HN: SlateDB – An embedded storage engine built on object storage https://ift.tt/3SPE7ic

Show HN: SlateDB – An embedded storage engine built on object storage SlateDB is an embedded storage engine built as a log-structured merge-tree. Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on). Leveraging object storage allows SlateDB to provide bottomless storage capacity, high durability, and easy replication. The trade-off is that object storage has a higher latency and higher API cost than local disk. To mitigate high write API costs (PUTs), SlateDB batches writes. Rather than writing every put() call to object storage, MemTables are flushed periodically to object storage as a string-sorted table (SST). The flush interval is configurable. To mitigate write latency, SlateDB provides an async put method. Clients that prefer strong durability can await on put until the MemTable is flushed to object storage (trading latency for durability). Clients that prefer lower latency can simply ignore the future returned by put. To mitigate read latency and read API costs (GETs), SlateDB will use standard LSM-tree caching techniques: in-memory block caches, compression, bloom filters, and local SST disk caches. https://ift.tt/kzhNv3K August 15, 2024 at 12:47AM

Show HN: AI Bartender in a Virtual Bar Note: The avatar will talk to you, so make sure you check your volume! Hello HN! I've seen a bunch of AI character type stuff online, but all of them were boring chat interfaces. I thought it would be more fun to give the characters an avatar and a 3d environment to interact with. The stack I'm using is Claude 3.5 for the LLM, OpenAI TTS, Stable Diffusion for generating drinks, and three.js for rendering. I exposed the prompt I'm using so people can play around with it by clicking the robot icon. If people find it interesting, I might add more environments, character customization options, etc. Hope you enjoy and let me know your thoughts/questions in the comments!

Show HN: AI co-worker for system software development (Rust,C,C++,pdf) https://ift.tt/I6c4UT2

Show HN: AI co-worker for system software development (Rust,C,C++,pdf) Hey Everybody, We are really excited to release the 1st version of H2LooP studio today. https://h2loop.ai/ H2LooP Studio helps system software engineers generate code from technical specs, debug issues, and understand complex code in C, C++, Go, and Rust. Under the hood, it uses the H2LooP Data Engine to create instruction-tuned datasets from data sheets and source code. Models are what they eat. We create high-quality, pre-vetted domain-specific training data (telecom, IoT, automotive, consumer electronics) at scale for fine-tuning small language models. We leverage both LLMs and human expertise (system knowledge) to build this dataset. Why are we building H2Loop? 1.Challenges in System Code: -System code presents significant challenges for LLMs that lack specialised pre-training. -Existing tools like GitHub Copilot struggle with tasks such as generating device driver code, debugging network kernel crashes, and interpreting hardware schematics. 2.Limitations of Current Coding Assistants: -Results from generic coding assistants are often unclear and insufficient. -These tools are unable to handle technical specifications or crash logs, which are essential for system software development. -System developers frequently need to reference specifications like Wi-Fi, Bluetooth, or network protocols while coding, but current tools fail to meet these needs. 3.Specialised Requirements for System Software: -System software is typically written in languages like C, C++, Go, and Rust, often in closed-source projects. -Enterprises need specialised solutions that understand their specific domain and coding standards. Challenges in Generating Accurate Code from Technical Specifications: 1.Unstructured Format of Technical Specifications: -Technical specifications are often in PDF format, which is inherently unstructured. -Parsing PDFs that include images, tables, and various text elements, and aligning them with reference sample code, presents a significant challenge. 2.Difficulty in Creating Domain-Specific Datasets: -Developing a question-and-answer coding dataset for specialised domains like automotive or telecom, suitable for LLM training, is a complex task. 3.Necessity of Expert Review: -Expert review of the training dataset is crucial. For example, if a dataset is created for socket creation in a networking protocol, it must be meticulously checked by an expert before being used for fine-tuning. The Solution: 1.RAG-Based Parsing and Chunking: -We employ a Retrieval-Augmented Generation (RAG) solution to parse and chunk PDFs effectively. -By combining LLM and manual methods, we align the content from PDFs with source code to create an instruction tuned dataset. 2.Expert Review and Validation: -Our team of system and domain experts thoroughly review and validate the training datasets, which are formatted in JSON. 3.Collaborative Fine-Tuning: -We partner with enterprises to transform their code and technical specifications into expert-vetted, domain-specific datasets. -We then assist in fine-tuning a small language model tailored to their domain and coding standards. Who can use H2LooP: H2LooP is a valuable tool for professionals like developers, product managers, and CTOs. If you're working on proprietary software, frequently coding from technical specifications,H2LooP is for you. Demo: https://ift.tt/voWkFIz H2LooP Studio is hosted in the cloud. You can download sample technical specifications and experiment with the H2LooP model to generate system software code. We will soon be releasing the H2LooP Data Engine, which will allow you to create training datasets by uploading code and PDFs. For more details, refer to https://ift.tt/s5S8q4v Also please join our community at : - Slack : https://ift.tt/B02NjJR - Twitter : https://x.com/h2loopinc Would love to hear your feedback & how we can make this better. Thank you, Team H2LooP https://h2loop.ai/ August 13, 2024 at 09:02PM

Show HN: Rust GUI Library via Flutter Hi, I made a bridge ( https://ift.tt/vilEN5q v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I first released 1.0.0 years ago, it only contained few features compared to today. It is the result of the hard work of contributors and me, and many thanks to all the contributors! https://ift.tt/F59qtiU August 11, 2024 at 08:25AM

Show HN: Midsommer" or a way to create self-organizing maps in JavaScript https://ift.tt/TUWuiNF

Show HN: Midsommer" or a way to create self-organizing maps in JavaScript I've been obsessed with self-organizing maps (or Kohonen maps) for a few years now, and I made a library that implements a bare-bones SOM algorithm in JavaScript. A SOM is basically a kinda-old school—but effective—way to do dimensionality reduction and clustering. Midsommer, my library, also comes with a Svelte component to visualize the resulting SOM, and it uses a force-directed graph to display the underlying shape of the map (cosine similarity between adjacent neurons informs the edge weights, basically). You can see the code here, as well as a couple examples, including one that represents the ~300-odd books I've read since the start of the pandemic. I'm really curious what people think. https://ift.tt/4xiyvNP August 11, 2024 at 12:20AM

Show HN: Made an anonymous feedback app TeamSays https://ift.tt/iWTrYwn

Show HN: Made an anonymous feedback app TeamSays Hi HN, it’s Kaz. I’m a dev/solo founder here with my startup TeamSays [0], which is an anonymous feedback channel for improving workplace experience. Put simply, it’s like a founder/HR manager’s always-on sidekick. The product idea grew out of personal experience in startups and ~600 employee org, and me learning the shocking stats of the costs for replacing talent. To those of you who have a job: replacing you would cost your employer ~20% of your annual salary [1]. If you’re highly specialized (which is very likely) it can cost up to 4x your annual salary [2]. So, keep that in mind when you negotiate your compensation or work-life balance. Here’s how TeamSays works: 1. Once you create an account you get a link to a minimal chat-like UI, you only have to create categories and questions. 2. Then you share link with your team announcing a new channel for tracking feedback/issues. 2. Team members visit and share something, you can then see their conversations get analyzed, and turned into a positive or negative report that becomes visible in the dashboard. 3. That’s it. Nothing else to do other than update or remove questions/categories over time — minimal maintenance. 4. Get weekly/monthly reports on the state of positive/negative reports and take action. Over time you can track progress of issues as active questions get rotated, so on a long-term timeframe you can derive progress stats and see where things went right/wrong. Essentially, it’s a channel for your team members to express their true concerns and opinions (possibly in explicit manner that otherwise wouldn’t be possible), which simplifies work of HR department if you have one or becomes one if you don’t. Personal conflicts, stress/anxiety, or simply not feeling safe/confident enough are possible reasons to have this channel. The chat is fully anonymous and it does not provide any way to identify participants other than a simple browser-based ID. I’ve personally experienced bad managers in otherwise good enough organizations. As a remote team member building personal connection for transparency is hard. We all know the old saying “people quit managers, not companies” which might not be 100% true [3] but I do find it to be true enough to base TeamSays around it. Obviously, TeamSays is not for every team/organization out there but for those that value transparency and simply want to make sure they have a safe, and private channel that is remote-friendly for their colleagues, clients, or employees I believe it’s a good tool in the arsenal and I hope you consider giving it a go. Improving team experience, and providing space where everyone can truly share their concerns and keep their privacy/anonymity. Even a simple fact of sharing issues could be beneficial if there is no alternative at all. Here are some stats: 1/3 of modern day workers wouldn’t accept a job if they didn’t agree with the views of the leadership [4]; managers must use meaningful interactions to build engagement [5] as remote employees’ connection to their organization’s purpose is declining. Lots of metrics point to a high expectations of modern day workplace, and I’m here to offer help to HR process — there is a free 7-day trial, and setting it up should take only a few minutes. I made sure TeamSays supports numerous languages, and am doing my best to add more. Please share your thoughts. Thank you. [0]: https://teamsays.com [1]: https://ift.tt/NyVgFxl...

The notifications will pop up at intervals, displaying words and their translations to keep you engaged and learning. The CSV can be very long, just put first row be the word and the next row same column be the translation Built with JavaScript, utilizing the browser’s notification to deliver reminders. reason of making I created this app to make learning German more convenient and integrated into daily life. It’s an attempt to turn passive time into productive learning moments. try it You can upload a CSV file with your target vocabulary and start receiving notifications right away. The app is free to use and doesn't require any setup beyond uploading your word list. If you have any feedback or feature requests, I’d love to hear from you. Thanks for checking it out! https://ift.tt/q30Ycdg August 10, 2024 at 03:26AM

Show HN: One status page to rule them all (aggregating 3k status pages) I recently got tired of subscribing to dozens of status pages (Cloudflare, Vercel, Twilio, GitHub, OpenAI) just to stay ahead of the outages that seem to happen almost every week. So I decided to build https://ift.tt/Cv0Eo4m - essentially it's an aggregator that crawls 3,000 status pages every minute, so I can see the status of all services and infrastructure in one central place. I also added the capability to create a custom dashboard so that you can monitor specifically the services that you use. I built StatusSight using Next.js, with the frontend being deployed to Vercel, and the status page monitor deployed to Hetzner with Coolify.

Show HN: Spawn – Build iOS Apps with English Hi HN, Spawn lets you build apps with human language. You can include images, audio and other files in your app just by dragging and dropping. Here's a demo video where I build the game of Snake in 60 seconds: https://www.youtube.com/watch?v=qIqp7cvmE_M As it’s still in alpha, you may need to regenerate a few times to get the app functioning the way you want. So far I’ve found it’s pretty good at generating simple utilities and games. Over time, as both Spawn and the underlying models improve, it will be able to build more complex software. I have a bunch of ideas for future updates, for example: - Allow users to include wireframes that Spawn will follow as it generates their app. - Android support in Mac, Windows & Linux Spawn desktop app. This way, people can use Spawn to build for both mobile platforms using the same app specifications. Imagine someone living in rural India using their Chromebook to build apps for their Android phone, without needing to learn how to code. - Enable people to build apps that have accounts and backend logic by autogenerating and deploying a backend during app generation. Any feedback would be greatly appreciated. https://spawnapp.com/ August 6, 2024 at 09:28PM

Show HN: I built interactive map of active and decommissioned nuclear stations https://ift.tt/rNOTIpY

Show HN: I built interactive map of active and decommissioned nuclear stations Hi all, I am not an expert in nuclear energy but I've always wondered and found it difficult to get a clear picture about the amount of nuclear stations located in a specific region. So I built this tool that shows all the nuclear plants in the world, scaled by their capacity and with indication of their status. Clustering is enabled by default and allows to see the sum potential capacity of a region. It's a fun tool for me: e.g. disable clustering, scale circle radius to 70%, go to EU, and you'll see Germany has shutdown all of the stations. Ofc it's a widely known fact, but what came to my surprise is that Poland, Turkey, Scandinavian countries, Africa have literally 1 to none nuclear stations. Which is kinda strange because some of these regions are modern, well-developed, and Africa specifically was sourcing lots of nuclear fuel for other countries other the years. idk what to do with it yet, but I think I'll come up with ideas for future improvements as I believe nuclear sector will grow drastically. https://ift.tt/eOzBPpu August 8, 2024 at 01:10PM

Show HN: Voyage – Toolbox of otherwise expensive SaaS marketing tools https://ift.tt/MR1wsX2

Show HN: Voyage – Toolbox of otherwise expensive SaaS marketing tools Voyage is a bunch of marketing tools for SaaS in one platform. We're betting on three things: 1. Many marketing tools don't offer free tiers. Think Optimizely, 6sense, Mutiny, Typeform, Qualified, Marketo, Drift, etc. A lot of these have minimum contract sizes of 5 figures. Voyage is completely free right now (haven't shipped monetization yet) and will always be usage-based + free tier. 2. Having these tools in one place compounds. We offer global themes for all of the user-facing marketing assets, which means you won't have to manage a brand theme for each of Wistia, Drift, etc. We also can use the data from one tool to modify another. Ex: personalize the header of the pricing page based on whether a visitor went through the video on your splash page. 3. We can outship most engineering teams in the long term. It's difficult for mar-tech companies to attract/retain talent since they're GTM-first, not eng-first. We're building an eng-first mar-tech company, getting into teams early with a generous free tier, and making money as our customers scale. We can probably offer these tools much cheaper at bundled scale too. If you use any of these tools and want to combine them together for a reduced bill or better cross-tool integration, please reach out. We'd love to have you as a design partner. - Wistia / Vimeo - Typeform / HS forms - Optimizely / Mutiny - Google Analytics 4 - Drift / Qualified / etc - SEO content tools bryan.houlton@withvoyage.com https://ift.tt/LYfk0Fs August 8, 2024 at 04:25AM

Show HN: Muky – A kid-friendly music player for iOS Hi, I've developed an iOS app called Muky ( https://muky.app/ ) that allows parents to create and manage music playlists for their children. It provides a focused, distraction-free audio experience for kids. I created this app because my 4-year-old daughter loves music, but existing solutions like Tonies or cassettes didn't meet our needs. Using an iPhone or iPad directly with Apple Music wasn't ideal either. Muky aims to solve these issues under the motto "Music for the Kids". Here some key features: * Dedicated music player for children * Parent-controlled playlists * Compatible with Apple Music (Spotify support coming soon) * Distraction-free interface * Works well with iOS "Guided Access" feature * Keeps kids' music separate from parents' personal collections and algorithms * iOS 15 Support for Older Devices * Direct Start in Audio Player * Password Protection (Secure the audio player mode with a password. Exiting the audio player mode requires the password set by the parents, ensuring kids cannot exit the app simply.) I'd love to get your feedback and hear your thoughts on this approach to kid-friendly music streaming. https://muky.app August 5, 2024 at 12:36AM

Show HN: Datoviz 0.2.0, Vulkan-based GPU scientific visualization (C/C++/Python) I'm excited to announce the release of Datoviz 0.2.0, an open-source, high-performance GPU scientific visualization library built on Vulkan. It targets the interactive visualization of large 2D/3D datasets. This version includes tentative precompiled Python wheels for Linux, macOS (ARM and Intel), and Windows. Datoviz is a key part of the CZI-funded Vispy 2.0 project and will serve as its main GPU backend. Datoviz provides core GPU visualization capabilities while VisPy 2.0 will provide high-level plotting functionality (a bit similar to NumPy vs SciPy). What I'm looking for from the community: 1. Compatibility feedback: I'd appreciate quick feedback on how these precompiled Python wheels perform across different operating systems and graphics hardware. 2. Library feedback: Datoviz is still in its early stages and actively evolving. The API is subject to change, and I'd appreciate any feedback on its functionality and design. Please report issues on GitHub. Since the initial 2021 v0.1 release, the underlying technology has matured significantly. The internal architecture is now more robust and modular, paving the way for support for other rendering technologies like WebGPU and WebAssembly in the medium term. While still somewhat limited, the focus is on ensuring stability, performance, and visual quality. Available visuals include points, markers, line segments, paths, glyphs, images, spheres, 3D meshes, and basic volume rendering. Some important features, like axes and picking, are planned for v0.3 and later. Please give it a try, report any issues on GitHub, and feel free to ask questions. You're also welcome to contribute. I'm looking forward to your feedback! https://ift.tt/SWd3jQH August 6, 2024 at 01:33AM

The site itself is of course also vanilla and open sourced on github. https://ift.tt/qzj2Xd5 August 3, 2024 at 10:45PM

Show HN: I built a solcial-media-inspired fitness App https://ift.tt/TGLlqcK

Show HN: I built a solcial-media-inspired fitness App Hi Hacker News! I'm Jarne, a student and software developer, and I have developed MyGainplan for the last 2 years. When I started working out, I realized that it is quite hard to keep varying training plans. I know that it is recommended to change your training plan every 2–3 months in order to prevent muscular imbalance and other injuries. Besides that, some little changes help to stay motivated on a long fitness journey . After endless searching for free workouts or training plans, I had the idea of MyGainplan. The main idea of MyGainplan is to allow users to share their experience and profit from each other. MyGainplan guides you through your workouts, tracks your progress and keeps you motivated to train. When it comes to discovering new workouts, MyGainplan allows you to search for unique and different workouts created and uploaded by other users. With that, changing your training plan becomes a breeze - And it's totally free! No payments, no subscriptions, no advertisements! I am so happy to say that I have now launched on iOS and Android. I would love to get some Feedback from the first users in order to make MyGainplan even better!

Show HN: webhooked.email (2023) Hey HN, I built this tool a while ago, and it looks like it's finally getting some traction lately -- wanted to post it up again here for anyone who's looking for a dead simple solution for webhooks that email you. For those who say new products are hard to trust ("you never know how long they'll be around!") -- this one has been casually running for just over 13 months now! https://webhooked.email August 3, 2024 at 07:47AM

Show HN: Trayce – Network tab for your local Docker containers https://ift.tt/3oU4VlR

Show HN: Trayce – Network tab for your local Docker containers Trayce is an open source desktop application which monitors HTTP(S) traffic to Docker containers on your machine. It uses eBPF to achieve automatic instrumentation and sniffing of TLS-encrypted traffic. As a backend developer I wanted something which was similar to Wireshark or the Chrome network tab, but which intercepted requests & responses to my containers for debugging in a local dev environment. Wireshark is a great tool but it seems more geared towards lower level networking tasks. When I'm developing REST APIs I dont care about packets, checksums, bit flags etc. I'm only concerned with HTTP requests and their responses. I also didn't want to have to configure a pre master key to intercept TLS, I wanted it to work out-of-the-box. Trayce is in beta phase so feedback is very welcome, bug reports too. The frontend GUI is written in Python with the QT framework. The TrayceAgent which is what does the intercepting of traffic is written in Go and eBPF. https://trayce.dev July 31, 2024 at 12:28AM

Show HN: Anyma V, a hybrid physical modelling virtual instrument https://ift.tt/MAoy0vG

Show HN: Anyma V, a hybrid physical modelling virtual instrument Hi HN! We're a small team in Lille (France) who make synthesizers and MIDI controllers. We've just released a virtual plugin version of our hardware synth Anyma Phi, which offers a semi-modular environment with a focus on physical models, although there are several other kinds of synthesis. Here's a video: https://www.youtube.com/watch?v=6efDQ9GmRpg We're not pivoting to VSTs, it's just that it was a practical way of investigating several issues and helping us with the ongoing development of our upcoming Kickstarter-backed synth (Anyma Omega) and MPE controller (Loom), and a gift to thank our backers for the wait they gave to go through due to several manufacturing and production issues. I enjoy reading music-related entries here, so I thought I'd contribute this time and I hope it will interest some. I'm here for any question or remark. https://ift.tt/nK1OEW4 August 2, 2024 at 12:05AM
