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 01:53AM

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 09:27PM

Show HN: Coffee Beans Tracker with OCR Inventory Management on GPT I brew coffee and I buy a lot of beans. I’m also a lazy person that doesn’t want to type in all the details in one of the available apps and track things to the grams. Luckily I found out that GPT-4o (free tier) is good enough to take a few photos I uploaded of a bag and parse it’s roaster, varietal, origin, tasting notes, roast date, etc. I tried with a dozen different bags and it works pretty well - even when it makes mistakes I can correct them with natural language conversation, which I enjoyed. Then I had to figure out storage. I don’t want to rely on the chat history / context as a way to store info as that can easily get lost. I discovered GPT Actions. My immediate thought is to give GPT some access of an online scratchpad that it can read and write and call it a day. That’s how I ended up integrating it with GitHub Gist. I created an empty gist file, and generated an app access token that reads/writes gist files

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.

Show HN: FlowG – A low-code log management software proof of concept Hi there, author here. At $workplace, we needed to be able to easily refine and route logs from multiple heterogenous sources into dedicated destinations (here called "streams"). We are not fans of ELK for totally subjective reasons, and needed something extremely simple, hence this project. The entrypoint is a pipeline that you write in "no-code" (using React Flow). The pipeline takes log records from the source and transform/refine them using the VRL scripting language, and can conditionally route them to one or multiple streams, which you can then query. The project was made in 4 days, there are no benchmark yet (soon to come, as we need to assess at $workplace if it can handle our load), it's very early stage, but feedback will be welcome. https://ift.tt/3HZWoV6 August 22, 2024 at 09:56PM

There are several differences and nuances in ethnic clothing and items that existing platforms like Depop or Vinted do not cater to. I launched the MVP for a C2C marketplace that taps into this frustration, a dedicated space for culturally relevant items that contributes to sustainability via the circular economy. Most South Asians do not re-wear their ethnic clothing and PurvX allows them to monetize them.

The rise of DuckDB has abundantly made it clear that even for many workloads of Terabyte scale, a single node system outshines the distributed query engines of previous generation such as Spark, Snowflake etc in terms of both performance and cost. Now a lot of workloads DuckDB is used for were normally considered to be “big data” in the previous generation, but no more. In the context of streaming especially, this problem is more acute. A streaming system is designed to incrementally process large amounts of data over a period of time. Even on the upper end of scale, productionized use-cases of stream processing are rarely performing compute on more than tens of gigabytes of

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 returne

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 int

Show HN: Coompare – A daily contest to upload and rank AI-generated images I made Coompare after experimenting with many different image generation models such as Midjourney, Dall-E and others. Each model has different prompt and language requirements in order to extract the most out of it and generate the best image possible. I wanted to make the process of learning to write prompts much easier and to visually demonstrate the differences in image results with prompts using different models. Coompare hosts a contest every day, each with a different theme. Users can upload a maximum of 1 picture per day (they can delete and resubmit at any time) to the contest. Head-to-head matchups are generated for different pairs of images with the results affecting that player's rating. By the end of the contest, the photo with the highest rating wins! I hope that Coompare becomes a place to browse some really cool artwork from many different artists and models and to inspire creativity through

Show HN: OpenRouter with Guardrails (Jailbreak, PII, etc.) Hello HN! We have been working on an open source routing mechanism that has built in guardrails (i.e. preventing jailbreak, injection, PII leakage). It's really similar to OpenRouter but we've added a guardrail mechanism to it. These guardrails are highly extensible but have focused around natural language based interactions (e.g. you have a chatbot that you don't want leaking PII). Some our guardrails are other open source models (like Metas prompt guard they released with 3.1 or Microsoft Presidio). Would love feedback to see what folks think! Thanks! https://ift.tt/ifEhxMV August 12, 2024 at 10:48PM

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

Show HN: Anyquery – A SQL query engine for anything Hey HN, I’m Julien, and after finishing my CS sophomore year, I wanted a project to keep me busy during the summer. So I built anyquery for fun, a SQL query engine for pretty much anything. SQL is the industry standard query language for databases. But what if it could query other services? That’s what I wanted to explore. Kinda like Yahoo! Query Language, except that I was too young to see it. Anyquery can run queries on local/remote files (CSV, JSON, logs with Grok, Parquet, HTML tables, etc.), SaaS (GitHub, Notion, Spotify, etc.) and local apps (Apple Notes, Git, Google Chrome tabs, etc.). I’ve built 35 integrations. Anyquery can also transform a Google Sheets or an Airtable base into a SQL database with INSERT/UPDATE/DELETE support. Additionally, it can act as a MySQL server to leverage its ecosystem (BI tools, ORMs, etc.). Finally, you can run PRQL and PQL (KQL inspired language) queries with it. Under the hood, it uses Go and SQ

Show HN: LLM Aided OCR (Correcting Tesseract OCR Errors with LLMs) Almost exactly 1 year ago, I submitted something to HN about using Llama2 (which had just come out) to improve the output of Tesseract OCR by correcting obvious OCR errors [0]. That was exciting at the time because OpenAI's API calls were still quite expensive for GPT4, and the cost of running it on a book-length PDF would just be prohibitive. In contrast, you could run Llama2 locally on a machine with just a CPU, and it would be extremely slow, but "free" if you had a spare machine lying around. Well, it's amazing how things have changed since then. Not only have models gotten a lot better, but the latest "low tier" offerings from OpenAI (GPT4o-mini) and Anthropic (Claude3-Haiku) are incredibly cheap and incredibly fast. So cheap and fast, in fact, that you can now break the document up into little chunks and submit them to the API concurrently (where each chunk can go through a multi-stage

Show HN: RoundtableJS – Open-source programmatic survey library Hi Hacker News, We’re Matt and Mayank of Roundtable. We’re launching RoundtableJS, an open-source library ( https://ift.tt/dZJqFgh ) to program research surveys at scale. Academic and market researchers want a DIY platform for survey research. Most existing tools are no-code, and these researchers want programmatic software that handles advanced branching logic and customization. We know this because we spent five years using open-source survey software for our academic work. One of the key insights of RoundtableJS is to leverage JavaScript’s async/await functionality for managing survey logic. In other libraries survey logic is determined via callbacks that trigger when a page is submitted (i.e., if the user answers “Yes” to Q2, show page 3), which quickly becomes a nightmare to manage and debug. Our library lets developers build the timeline in an async function which means the logic flows intuitively from top to bottom.

Show HN: We Open Sourced Our GitOps Template for ArgoCD We have been using GitOps internally for years, to leverage infrastructure as code for our Kubernetes clusters. With the recent release of the GitOps mode for Glasskube, we decided to open source our GitOps template. This template helps you get started with GitOps in minutes instead of hours. Previously it was always a struggle to setup your Kubernetes Cluster with the GitOps approach leading to teams manually deploying manifests and helm charts which results in Kubernetes clusters that are hard to maintain. As of today git is still the most popular solution for managing your Kubernetes Cluster with IaC. The GitOps template uses the ArgoCD's App of Apps model and all packages (including ArgoCD itself) will receive automatic update suggestions via pull requests thanks to the Renovate and Glasskube integration. In order to get started, you just need to create your own repository from our template and bootstrap it with a single c

Show HN: Launch React components in your app with no-code Hey HN! I've built a way to launch simple, stateful React components like promotions, banners, and announcements in your web app through reusable in-app UI channels. Here's a demo of how it works: https://youtu.be/qrPip41Ecyg . The docs are here: https://ift.tt/ukEh4tC . This enables non-technical teammates to launch native, prebuilt components directly in the product UI without involving engineering. We also provide the ability to update content (i.e. CMS), track user progress/state and target components to specific users from our admin panel. The new feature, called Collections ( https://ift.tt/DMRXCZI ), works by embedding a channel directly in code — think of it as a that can spawn an inline React component – or on the floating z-index level. For instance, a channel for UI cards that sits directly in your dashboard or floating experiences like surveys and popups. Collections can be styled using your own design system

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 w

Show HN: 1-FPS encrypted screen sharing for introverts I wanted to show you something I was hacking on for the last few weeks. I tired of sharing screen via Google Meet with 1-hour limitation, with Zoom and 40-minute limitation, etc. With paid Slack subscription. And often times I just needed to screenshare with no audio. So I ended up with my own solution - no registration, low memory, low CPU, low tek 1 fps encrypted screen sharing. Currently sharing only the main screen (good for laptop users). It's very raw in terms of infrastructure, since I'm not counting bytes (yikes!), everything works on my own dedicated server. But the service itself has been tested, we've been sharing screens for countless hours. All sessions last for 48 hours, then it gets removed with all remaining info. Every new frame replaces the other, and everything is end-to-end encrypted so even server owners and operators won't be able to see what are you sharing. There is also no tracking, except t

Show HN: Visual a* Pathfinding and Maze Generation in Python I was fascinated reading through another recent HN submission about a highly efficient implementation of A* in Lisp, which got me thinking about how I could do something similar in Python. However, these kinds of pathfinding algorithms really need complex terrain/mazes with interesting obstructions to showcase what they can do and how they work. So, I started thinking about how I could generate cool and diverse random "mazes" (they aren't really mazes, but I'm not sure what the best term is). I got a bit carried away thinking of lots of different cool ways to generate these mazes, such as cellular automata, fractals, Fourier transforms, etc. Then it turned out that many of the generated mazes weren't actually solvable, so I spent some time coming up with various strategies to test and validate the generated mazes and then modify them so they would work better for this purpose. I spent a fair amount of ef

Show HN: A singing synthesizer for the browser with algorithmic 3-part harmony Hello HN! This is a demo I built during my batch at the Recurse Center. It's built using WebAudio, WebAssembly (via Rust), and the Canvas API. The source code for this demo, along with my other vocal synthesis related RC demos[0], can be found at a monorepo[1] where I've been dumping all my RC work and logs. The sound is generated using a physical model of the human singing voice, using a work-in-progress project called VoxBox [2]. The harmonization is done using something that kind of resembles a markov chain. Only, instead of using weighted probabilities and randomness, I use a selection heuristic that chooses a chord based on how often it has been used and how much voice movement is required.
