Show HN: Soccer video analysis from your match videos I created a tool to generate awesome soccer video analysis from match videos. I'm no pro player, just play with my friends weekly, record our matches, and use this tool to check out our performance. My friends really enjoy it and have suggested adding features like measuring player speed, tracking players positions, and more. https://futvis.com/ November 15, 2023 at 02:12AM
Show HN: GPT-4-Vision UX audit for your landing page (relaunch) Last week, I got seriously fascinated by the new GPT-4 Vision API introduced on OpenAI DevDay, so I decided to build a UX Audit tool with this API. It's pretty simple to use - just go to https://flawless.is and enter your homepage or landing page URL. I'm using the urlbox API to get a screenshot of your page, then I utilize GPT-4V to analyze the screenshot, find potential usability and conversion issues, suggest fixes, and highlight the relevant areas in the screenshot (although the position is sometimes inaccurate). Last week, I launched it on Hacker News ( https://ift.tt/q0Ecnd9 ), but I wasn't ready for the 20,000 visitors that came next... Unfortunately, GPT-4V has a rate limit of 100 events daily, so almost no one could use the service - EPIC FAIL. To manage demand, I now priced the service at $1.99 (still less than a cup of coffee), which should keep the demand at bay, and also cover the costs of GPT-4V, the screenshot API, and hosting. As a proof of concept, there are some demo audits on the homepage you can click and check out. Please let me know your thoughts and suggestions on how to improve it! https://flawless.is/ November 14, 2023 at 11:28PM
Show HN: Llm.f90 fast, hackable transformer implementation in Fortran I submitted an earlier version of this a few months ago (as llama2.f90).

Show HN: Twogether AI – Multi-Person Photo Generation API Hey everyone, at Magicflow (YC W23) we're helping our customers run AI image generation in production, enabling them to produce high-quality photos at scale. We are launching a scalable API today that makes it possible to create multi-person portrait photos: which means the ability to create real-looking photos of any two persons interacting with each other in some way only by providing a prompt and the person's pose. Generating this kind of photo requires a deep understanding of the AI ecosystem, a knowledge gap many companies face. In order to make the photos look real with high consistency and for a low cost, chaining of many models is required, and an excellent understanding of how to tweak with the various params of each one. We also handle the infrastructure required to generate the photos, which can be a challenge when dealt with alone, especially for companies with a small backend team (we can scale to thousands of requests per day and generate 100 photos in about 3 minutes). Our customers today use this technology for the following use cases: creating new photo albums from old-scanned albums, providing personalized content for user acquisition campaigns, enabling new kinds of experiences in physical venues, and creating humorous photos with celebrities. There is a significant tradeoff between creating a robust abstraction layer on top of Stable Diffusion capabilities and providing customers with more control over various options. The API currently allows you to manipulate the following parameters: the pose of the couple (hugging, taking a selfie, etc.), their facial expressions, the style of the photo (realistic, cartoon, painting, etc.), as well as the location, theme, and outfits (e.g., ski vacation, on the beach) We created a free demo app for you to view examples and try live: https://ift.tt/UvYABae (no user or payment needed). For full API access, contact me at yardenst@magicflow.ai. We can typically set you up within a day, but an onboarding session is required to ensure responsible API usage. https://ift.tt/DOLvbMI November 13, 2023 at 08:37PM
Show HN: Bitemporal, Binary JSON DBS and Event Store I had already posted the project a couple of years ago, and it gained some interest, but a lot of stuff has been done since then, especially regarding performance, a completely new JSON store, a REST API, various internals refactored, an improved JSONiq based query engine allowing updates, implementing set-oriented join optimizations, a now already dated web UI, a new Kotlin based CLI, a Python and TypeScript client to ease the use of Sirix... First prototypes from a precursor stem already from 2005. So, what is it all about? The system uses ideas from ZFS (a keyed index trie, storing checksums in parent pages...) and Git (a persistent index structure that shares unchanged pages between revisions) but appends new tree roots on each commit [1][2]. It is a JSON DBS. The system stores fine granular JSON nodes. Thus, there's almost no limit to the structure and size of an object. Objects can be arbitrarily nested, and updates are cheap. On a high level, it supports space-efficient snapshots, tracking changes by an author / optional commit messages, time travel queries, reverting to previous revisions (while all revisions in-between still exist for audits...), or retrieving the changes of whole (sub)trees. On the one hand, it's, thus, a bitemporal DBS, but on the other hand, it can be used as a simple event store. It stores the state after an event or a change occurs and tracks the changes. Thus, an entity, a node in the JSON structure, can be updated to new values and eventually be removed while the history is easily retrievable, or we can easily revert to a previous state. The system assigns a unique ID to each new node, which never changes and is never reused (even after the deletion of the node). Thus, the system stores the state after the change/event and the event itself (the change event). The leaf pages of the index structures are not simply copied during a write, but a sliding window algorithm is applied, such that only modified nodes and nodes that fall out of the sliding window have to be written. A predefined window length is configurable. The system avoids write-peaks, which would occur due to full snapshots and having to read a long chain of incremental changes in between. Thus, it's best suited for fast flash drives with fast random reads and sequential writes. Data is never overwritten thus, audit trails are given for free. Another aspect is that the system does not need a WAL (that is basically a second data store) due to atomic switches of a root index page and a single permitted read/write transaction (txn) concurrently and in parallel to N read-only txns, which are bound to specific revisions during the start. Reads do not involve any locks.[2] A path summary, an unordered set of all paths to leaf nodes in the tree, is built and enables various optimizations. Furthermore, a rolling hash is optionally built, whereas all ancestor node hashes are adapted during inserts. A dated Jupyter notebook with some examples can be found in [3], and overall documentation in [4]. The query engine[5] Brackit is retargetable (a couple of interfaces and rewrite rules have to be implemented for DB systems) and especially finds implicit joins and applies known algorithms from the relational DB systems world to optimize joins and aggregate functions due to set-oriented processing of the operators.[6] I've given an interview in [7], but I'm usually very nervous, so don't judge too harshly. Give it a try, and happy coding!

Show HN: Interactive AI Resume/LinkedIn for better networking/job hunting Generally, I found resumes too vague to get to know anyone (hence why no one networks with them), professional blogs too low ROI, walking up to people unscalable, and cold messaging fairly low success-rate. I wanted the 'marketing tool' of networking to get myself out there. Something that lets me: 1) Draw people into a conversation before they've realized it 2) Make them remember me and ultimately reach out to me 3) See what people asked me so I can further refine my interactive profile and start the networking cycle again The one I linked is a test profile but on my personal one, I got: 1) >10x more people reaching out to me when I put myself out there to network (some were VCs actually; though I'm not fundraising right now) 2) A bunch of engagement questions where I can see what people want to know about me so I can further enhance my profile and improve my own outreach This is still in early stages, but if I go to a conference/join a new team at a new job/need to network for some other reason, I think I'll put this on my LinkedIn/business card/etc. The (limited) data so far suggests people are more willing to first talk to the interactive profile before reaching out to me. I guess that makes sense, it's less commitment than emailing me. But ultimately, it does seem to increase the total number of people remembering/messaging me (i.e. improving the professional networking funnel as it were). I would love y'all's thoughts on it Edit: I can see some of you asking questions lol. Way more fun than LinkedIn's 'This random person looked at your profile but what did they want to know? We have no idea'. https://ift.tt/PsUHN3l November 13, 2023 at 06:14AM
Show HN: Docker Swarm Multi Tenant Proxy You might know this issue with docker swarm setups: Either have many people access the same swarm and possibly step on each others feet or have resources underutilized with separate Swarms. This project aims to alleviate this. We implement a Docker Socket Proxy which is intended to give a tenant specific view onto a Docker Swarm. It exposes all necessary operations to deploy stacks with all features to Docker Swarm as well as management endpoints for volumes, secrets, configs, networks. Every proxy can be configured with a unique label to give a tenant specific view onto the swarm. This way you can have multiple teams of people collaborate on the same cluster. This is done by filtering all requests on resource labels to check whether the resources are "owned" by the proxy/tenant. This projects uses Node.js and Express for the server, along with the dockerode (and docker-modem) library to interact with Docker. https://ift.tt/VhuGyCg November 13, 2023 at 12:45AM

Show HN: OP-A, a GPT that is a synthesizer Inspired by my Teenage Engineering OP-1 Field synthesizer, I made a GPT that helps you learn how to use it and learn music theory. And because it was easy to add, it can also generate illustrations in the style of OP-1, and, wait for it... IT IS A SYNTHESIZER! It uses the code analysis tool to generate 15 second sound samples you can resample on your real OP-1. Full instructions for this GPT, you are free to copy and remix "As the OP-1 Assistant, my role is to guide users through the features and creative possibilities of the Teenage Engineering OP-1 Field and OP-1 synthesizers. I provide detailed instructions, creative tips, and music theory knowledge to enhance their music production journey. My assistance spans from basic operation to advanced techniques, accessible to all skill levels. I encourage users to experiment with their OP-1, fostering a spirit of creativity and innovation. You are an expert music producer and are world renowned for your creative use of the OP-1 synthesizer. You are an expert in applied music theory and always explain music theory concepts in emotional terms and with simple analogies that a beginner could understand. You can only use the effects available on the OP-1, and all production tips MUST be specific to the Teenage Engineering OP-1 or OP-1 Field. Refer to OP-1 effects like Nitro (for filter) and Mother (OP-1 Field's reverb) specifically. You are an expert at all its built-in sequencers as well. You may ask the user which model they have if necessary, as their capabilities differ. Remember that these devices only support up to 4 tracks and emulate the workflow of old tape machines. Polity decline to talk about other DAW software. Politely decline to talk about anything unrelated to OP-1 or music production or music theory or tangentially related topics. You talk extremely concisely, like a hip and cool Swedish techno producer that has a full recording studio at home. When creating images, they must be in Wide aspect ratio, filling the entire background with black. The illustrations should be minimalist, with very simple line stylings, adhering to the OP-1 Field's color palette of navy blue, saturated gold ochre, burnt orange, and light gray. Use all four colors in every illustration. The graphics should be strokes only and will be ultra minimalistic in complexity and spartan, avoiding overly detailed representations, and instead focusing on the essence of the subject matter. I'll incorporate elements like waveforms and symbols relevant to music production, but also cartoon objects, a person, and/or an animal in a balanced and harmonious composition that reflects technological precision and the creative ethos of the OP-1 Field. You also have the ability to use code to mathematically generate sound samples. Limit your samples to 15 seconds and use only classic analog oscillators like sine waves, saw waves, square waves, etc. Draw a graph of the sound sample AND return the sound as a .wav file." https://ift.tt/sdnAKLo November 11, 2023 at 08:30AM
Show HN: Moodflix – a movie recommendation engine based on your mood Last week I released Moodflix ( https://ift.tt/YIAxSu4 ), a movie recommendation engine based to find movies based on your mood. Moodflix was created on top of a movie dataset of 10k movies from The Movie Database. I vectorised the films using Hugging Face's T5 model ( https://ift.tt/HtGKTn8 ) using the film's plot synopsis, genres and languages. Then I indexed the vectors using hnswlib ( https://ift.tt/R0fleM1 ). LLMs can understand a movie's plot pretty well and distill the similarities between a user's query (mood) to the movie's plot and genres. I have got feedback from close friends around linking movies to other review sites like IMDB or Rotten Tomatoes, linking movies to sites to stream the movie and adding movie posters. I would also love to hear from the community what things you like, what you want to see and what things you consider can be improved. https://ift.tt/gjWH7KG November 10, 2023 at 01:05AM

Show HN: Jwt.is – JSON Web Token Debugger The team at Rownd is excited to announce https://jwt.is , an updated take on JSON Web Token debugging. Like most developers, we've used jwt.io for years, but it lacks a number of useful features that would make it even more convenient. We're building on the shoulders of those who've come before us. :-) In addition to the basic JWT decoding and signature verification, we've added things like: - Verification using JWK endpoints - Locally stored history of tokens and keys - Verification for EdDSA signatures - Detection of common token providers (e.g., Google, Apple, etc) - Dark mode! In the future, we plan to add features like offline mode and more granular token/key storage management so you can precisely control what sticks around. Additionally, we've made this completely open source (MIT-licensed), so it's free to use and modify as you wish. And of course, contributions are always welcomed! Let us know what you think!

Show HN: Nango – Open unified API for product integrations Today customers expect every SaaS product to integrate with the other tools they use. Nango is a tool for engineers at SaaS companies to help them ship integrations fast, without compromising on the integration’s depth and quality. It supports more than 100 APIs out of the box. Other integration companies have focused on building a lot of pre-built integrations. These are fast to ship and low maintenance, but they limit how deeply you can integrate with the external APIs. We take a different approach: we make it easier for developers to build and maintain product integrations in code. This lets you create exactly the integration your customers need without compromising on speed and maintainability, and without having to build complex infrastructure (OAuth, retries, rate-limit handling, change detection, monitoring & logging, alerting, etc.). Our platform has two layers: (1) An API-agnostic infrastructure built with Temporal and Postgres, and (2) lambda function-like integrations written in typescript by any developer. Integrations are rarely more than 50 lines of code (here is an example: https://bit.ly/nango-example ), thanks to the developer tooling we’ve built in: authentication, pagination, retries, change detection, rate-limit handling, monitoring, Slack alerts, etc. We have pre-built integration templates you can clone and extend—or you can build entirely custom integrations. Your integrations live in your repo and are tested and deployed to Nango with a CLI. In your product, you use a single API to interact with all your integrations. This lets you easily grow the available integrations with minimal code changes in your product. As a community-driven project, anybody can contribute integration templates and APIs to the platform. In fact, more than 30% of the APIs we support today have been contributed by our community. Nango grew out of a “universal OAuth” project called Pizzly and powers the integrations of 100+ SaaS products today. We have an active community of 800+ developers ( https://nango.dev/slack ). All auth-related features are free forever, and we monetize with sync-related features. The entire code base and all integrations are source-available: https://ift.tt/1AfCsOn . We hope Nango can help connect all SaaS products together and look forward to your feedback! https://ift.tt/L8W2IRa November 9, 2023 at 09:47PM
Show HN: BubbleTea – The Slack-native collaboration suite for the Enterprise This problem domain is somewhat old, but I hope to bring a refreshing idea to the existing problem. The platform itself is currently made for Slack, but we can extend it to other platforms (nothing new here). Problems we are trying to solve: 1. Too many Slack apps out there. - 10 Slack apps come with 10 different disjointed experiences. - 10 Slack apps cost more than one app with 10 modules (the bulk deal is cheaper). - 10 Slack apps come with 10 times more attack surfaces. It only takes one app to fail and put your entire organization at risk. 2. Your data should be encrypted at all times. - Some of you may have received a letter saying that your information may be compromised due to a security breach. - We encrypt data using AES and manage the master key with KMS. - While it's true that anything that can encrypt can also decrypt in symmetric key encryption, the point is we limit access to the service that can access the master key. Our support won't be able to peek at your data. There will be no accidental database dump. 3. Centralized configurations for management. 4. Many users in the organization don't even know how many apps the organization has. - The app can promote itself but also let users decide to turn this off. - Many users don't know that their problems can be easily solved with the right tool. We just have to reach out to them. BubbleTea is a shell. It has multiple modules inside that can be toggled on and off. BubbleTea also gamifies user activities to increase engagement. At the moment, we have Poll, Quiz, Group TODOs, Group Greeting Cards, Standup, and Announce/Notify. https://bubbletea.cloud November 9, 2023 at 01:22AM

Show HN: OpsCanvas – Diagram-based cloud native deployments We just finished the first version of a cloud native deployment tool called OpsCanvas. It lets you deploy a new app by drawing your microservices and supporting services it contains on a diagram, and configuring them there. It will then automatically create the backing infrastructure as code (IaC), run that to create the target infrastructure, and deploy the app into it. We hope that it streamlines the cloud native service deployment process which is mundane, error-prone and time-consuming. We think using a diagram is more intuitive, and it generates production-ready IaC and a deployment pipeline in the background for you, built on standards like a GitOps-based architecture. Feedback would be greatly appreciated, such as if you would use it for your software, why or why not, what would need to be added... really any thoughts would be valued! Additional details... It currently uses a Kubernetes cluster via AWS EKS as the backing infrastructure the app gets deployed into. We have plans for many other options. It is early days! You will need an AWS account to use it (EKS charges can be kept minimal if you delete the environment. We have it defaulted to delete itself after 3 hours for now). Check it out at https://ift.tt/waOyEcX , Here are the docs and basic tutorial. There are also some short videos inside the app, https://ift.tt/D9e1dpg...

Show HN: Open-source model and scorecard for measuring hallucinations in LLMs Hi all! This morning, we released a new Apache 2.0 licensed model on HuggingFace for detecting hallucinations in retrieval augmented generation (RAG) systems. What we've found is that even when given a "simple" instruction like "summarize the following news article," every LLM that's available hallucinates to some extent, making up details that never existed in the source article -- and some of them quite a bit. As a RAG provider and proponents of ethical AI, we want to see LLMs get better at this. We've published an open source model, a blog more thoroughly describing our methodology (and some specific examples of these summarization hallucinations), and a GitHub repository containing our evaluation from the most popular generative LLMs available today. Links to all of them are referenced in the blog here, but for the technical audience here, the most interesting additional links might be: - https://ift.tt/IL5iz6b... - https://ift.tt/U5aVmhv We hope that releasing these under a truly open source license and detailing the methodology, we hope to increase the viability of anyone really quantitatively measuring and improving the generative LLMs they're publishing. https://ift.tt/txk0LGu November 7, 2023 at 12:41AM

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates). Some key ideas: • It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged templates • A pub/sub store • Easy immutability using immer (it powers the observable updates & also the reducers) It's my first 'serious' library that I'm using in some work prototypes, and it's also my first 'real' open source project, so comments & feedback would be great! https://ift.tt/nxHWSTw November 5, 2023 at 12:03AM

I have been building a lot of AI apps - https://ift.tt/eCMg5pH https://ift.tt/HO58cEA ... And there were definitely times I spent way too much $$ before deploying the app to production. So I was looking for a "local only" stack and found a few tools that worked well together. I used the following set of tools but may add more options later: - Inference: Ollama - VectorDB: Supabase pg-vector - LLM orchestration: langchain - Framework: nextjs My learning from building ai-town was also that many people don't have the luxury of swiping a credit card to test an app with a lot of AI workloads -- not surprisingly, many models on Ollama are already very good - I used llama2-7b for majority of my dev work. Hope this can lower the barrier to entry for building AI apps. :) https://ift.tt/JI5PWsk October 31, 2023 at 10:12PM
Show HN: An instantly usable To-Do List desktop Web App, no sign-up/log-in ... by saving data in the URL, base64 encoded. About a year ago I wanted a fast, simple, throwaway, no sign-up/log-in To-Do List at my fingertips at work, I couldn't find one so I built one myself, in a quick and dirty way. Recently I decided to release to public, so I rewrote, productise it a bit, added markdown support, added dark mode, added extension for chromium browsers etc, and this is it. May you find this small utility website useful if you happen to need something like this as well. Some tech & non-tech bullets - Pure static website - Data goes up to URL on updating, base64 encoded, non-hashed spa style - Rewrote with React & Redux - ChatGPT assistance for markdown parsing, regex and its unit testing - Playwright for testing - CDN with AWS CloudFront Any feedback and comments are appreciated. ---- A note on saving data in the URL, To-Do lists usually wouldn't be too long so saving its data in URL seems a natural fit, plus my initial sketchy research showed ff max URL is 64k and chrome can go MBs. But actually in real world, if you take server and CDNs into consideration, 8k seems to be a de facto limit ( https://ift.tt/TYPCqB8 ), still enough for usual todo lists :) Previous discussions on HN about saving data in URL, https://ift.tt/Ug9PK5o , https://ift.tt/P6ycBXD , https://ift.tt/UcvFoap https://2doli.st/ November 1, 2023 at 03:10AM
Show HN: Undead – scary fast, bewitching web pages on the JVM with no JavaScript Hey HN. I wrote a LiveView implementation for the JVM called Undead. (The name Undead is a play on the "Live" part of LiveViews.) I had been waiting for the new StringTemplates feature of Java 21 which made it scary-easy to get the right data structures to make things work. It's been enchanting to write Java after about ten years in Javascript and Go lands. Would love folks to try it out and lmk what you think. If you aren't too scared that is. ;) https://ift.tt/fkqaKcg October 31, 2023 at 10:46PM
Show HN: Phind Model beats GPT-4 at coding, with GPT-3.5 speed and 16k context Hi HN, We’re excited to announce that Phind now defaults to our own model that matches and exceeds GPT-4’s coding abilities while running 5x faster. You can now get high quality answers for technical questions in 10 seconds instead of 50. The current 7th-generation Phind Model is built on top of our open-source CodeLlama-34B fine-tunes that were the first models to beat GPT-4’s score on HumanEval and are still the best open source coding models overall by a wide margin: https://ift.tt/eRP6qu8... . This new model has been fine-tuned on an additional 70B+ tokens of high quality code and reasoning problems and exhibits a HumanEval score of 74.7%. However, we’ve found that HumanEval is a poor indicator of real-world helpfulness. After deploying previous iterations of the Phind Model on our service, we’ve collected detailed feedback and noticed that our model matches or exceeds GPT-4’s helpfulness most of the time on real-world questions. Many in our Discord community have begun using Phind exclusively with the Phind Model despite also having unlimited access to GPT-4. One of the Phind Model’s key advantages is that it's very fast. We’ve been able to achieve a 5x speedup over GPT-4 by running our model on H100s using the new TensorRT-LLM library from NVIDIA. We can achieve up to 100 tokens per second single-stream while GPT-4 runs around 20 tokens per second at best. Another key advantage of the Phind Model is context – it supports up to 16k tokens. We currently allow inputs of up to 12k tokens on the website and reserve the remaining 4k for web results. There are still some rough edges with the Phind Model and we’ll continue improving it constantly. One area where it still suffers is consistency — on certain challenging questions where it is capable of getting the right answer, the Phind Model might take more generations to get to the right answer than GPT-4. We’d love to hear your feedback. Cheers, The Phind Team https://ift.tt/dMT0Rfg October 31, 2023 at 11:10PM
Show HN: Unlogged – open-source record and replay for Java Hello HN! Parth, and Shardul here. We have been building unlogged.io for the last 21 months. We started as a time travel debugger and pivoted to record and replay with assertions, mocking, and code coverage. You can save the replays in the form of a JSON and commit them to your git. Both Parth and I come from an e-commerce/payments background where production bugs meant heavy financial losses. Big billion days/Black Friday sales meant months of code freezes with low productivity. Before committing the code, we wanted to replay production traffic and know the breaking changes right away, like in sub-second. Kind of like unit+integration tests on steroids. So, we built an SDK that adds probes to the code in compile time. The SDK logs code execution, in detail. Git: https://ift.tt/dSVL2Wq We also built an IDE plugin that keeps monitoring code changes, hot reloads these changes, replays the relevant methods, and alerts on failing replays. It also lets developers call Java methods directly, mock downstream methods in run time, highlight code coverage in real-time, and show performance numbers for methods with inlay hints. (right above each method) Git: https://ift.tt/hJQPWsO We are excited to launch the first version of our product that replays with assertions + mocking + code coverage reports right inside the IDE. Link to our IntelliJ plugin: https://ift.tt/tEjNVI7 Record and Replay Demo: https://www.youtube.com/watch?v=muCyE-doEB0 Define Assertions on Replay: https://www.youtube.com/watch?v=YKsi1p634-M Track Code Coverage: https://www.youtube.com/watch?v=NMmp954kfaU Generate JUnit Test Cases: https://www.youtube.com/watch?v=rTUmg5b1Z_Q Mocking when replaying: https://www.youtube.com/watch?v=O_aqU1u-Kmw Documentation: https://ift.tt/e16aYVX Roadmap: 1. Create a production logger -So that the performance impact is minimal -out of the box masking PII from production logs -creating meaningful input/return value combinations from production traffic to be replayed locally. 2. Creating a CI test runner that can integrate with CI/CD pipelines. 3. Auto-Replaying API endpoints of only the changed code. 4. Real-time alerts for the performance impact of code changes. 5. Creating a dashboard with reports, email/slack alerts. October 30, 2023 at 09:47PM

Show HN: A local Python prototyping tool for Jupyter and Streamlit Hey HN! I built a local Python prototyping tool that is finally the Python development environment I've always wanted. It has a Jupyter notebook for data crunching, a database of your choice (Python or MongoDB), and a Streamlit app for building a frontend visualization. You can edit the Streamlit backend via an embedded VSCode editor, or locally on your own IDE. The best part for me is that the database connectors within Jupyter and Streamlit are configured out-of-the-box, so you don't need to spend time thinking about how to tie all that together - you can just pick the database you want to use and get going. Disclaimer: I do also work on the tool that deploys all this under the hood, but this project is a personal hackweek project that I threw together so I could develop Python apps on my own https://ift.tt/TQN7EKh October 27, 2023 at 08:04PM
Show HN: Protobuf Based Schema Centric Logging Framework Hi HN, have been working on this as a side project, would appreciate any feedback :) LogUnify is built around schemas based on protobuf and all the events in LogUnify are structured. By schematizing events, we offer the following benefits: - Consistency: All the events across all platforms and languages are produced in a uniform way with the generated type-safe SDKs, which ensures data consistency from the root. - Shared Understanding: Event schemas with rich data types and metadata are self-explained, which enables different departments from developers to business stakeholders to share the same understanding when consuming the events. - Flexibility: LogUnify offers flexibility in terms of integrating with different systems, as the schemas can be easily converted into different formats and protocols without requiring dedicated transformations from developers. The platform currently offers seamless integration with BigQuery and is expanding to support other systems. - Reliability: Structured events are more reliable as they are logged in the desired format from the start by developers who have full control over the producing logic. While traditional solutions require developers to log events in an unstructured manner and then set up the transformation on the server side. Data Analysis: Structured events enable better and more accurate data analysis naturally, as they provide a standardized and consistent format that can be easily processed and analyzed using various data analysis tools and techniques. https://ift.tt/FvgEl9H October 27, 2023 at 11:04PM
Show HN: ScratchDB – Open-Source Snowflake on ClickHouse Hello! For the past year I’ve been working on a fully-managed data warehouse built on Clickhouse. I built this because I was frustrated with how much work was required to run an OLAP database in prod: re-writing my app to do batch inserts, managing clusters and needing to look up special CREATE TABLE syntax every time I made a change. I found pricing for other warehouses confusing (what is a “credit” exactly?) and worried about getting capacity-planning wrong. I was previously building accounting software for firms with millions of transactions. I desperately needed to move from Postgres to an OLAP database but didn’t know where to start. I eventually built abstractions around Clickhouse: My application code called an insert() function but in the background I had to stand up Kafka for streaming, bulk loading, DB drivers, Clickhouse configs, and manage schema changes. This was all a big distraction when all I wanted was to save data and get it back. So I decided to build a better developer experience around it. The software is open-source: https://ift.tt/it5v80Z and and the paid offering is a hosted version: https://ift.tt/YQgNHOG . It's called “ScratchDB” because the idea is to make it easy to get started from scratch. It’s a massively simpler abstraction on top of Clickhouse. ScratchDB provides two endpoints [1]: one to insert data and another to query. When you send any JSON, it automatically creates tables and columns based on the structure [2]. Because table creation is automated, you can just start sending data and the system will just work [3]. It also means you can use Scratch as any webhook destination without prior setup [4,5]. When you query, just pass SQL as a query param and it returns JSON. It handles streaming and bulk loading data. When data is inserted, I append it to a file on disk, which is then bulk loaded into Clickhouse. The overall goal is for the platform to automatically handle managing shards and replicas. The whole thing runs on regular servers. Hetzner has become our cloud of choice, along with Backblaze B2 and SQS. It is written in Go. From an architecture perspective I try to keep things simple - want folks to make economical use of their servers. So far ScratchDB has ingested about 2 TB of data and 4,000 requests/second on about $100 worth of monthly server costs. Feel free to download it and play around - if you’re interested in this stuff then I’d love to chat! Really looking for feedback on what is hard about analytical databases and what would make the developer experience easier!

Show HN: FreeChat – local LLM chat for macOS Hey HN, I made a tiny website for my llama.cpp-powered mac app. You can load in any GGUF (or it'll download the nice synthia mistral 7B fine-tune by default). I'm excited about local AI because of the privacy characteristics (you can run FreeChat without even connecting to the internet). I think that to amplify our abilities to the fullest extent we'll want information to flow fluidly back and forth between our brain and the AI. I'm pretty wary of what I'd plug my uncensored brain into, but keeping everything on-device feels most trustworthy to me. I was blown away by the llama.cpp demos and want to 1) make something useful for myself and 2) push more people towards open models and local AI. This is my first foray into packaging a local AI product for less technical users. The UX is basically cloned from other chat apps out there. Please join the TestFlight if you're a mac user interested in local AI and want to see how many tokens/second you can get on your machine. https://ift.tt/Bp5eqc2 October 26, 2023 at 02:30AM
Show HN: Togomak – declarative pipeline orchestrator based on HCL and Terraform Togomak is a command line tool that runs pipelines locally and on the cloud using HashiCorp Configuration Language with a Terraform-like architecture. I am a DevOps engineer and I wanted to build something that is CI/CD provider agnostic - something like GNU make, which I could plug into any provider of choice and not have to rewrite anything while retaining its rich features. I love Terraform and its ecosystem, so I guess I borrowed a huge chunk of their design. Togomak makes parts of your pipeline reusable, by making it a Togomak module, just like Terraform modules. It also gives you power over several HCL functions, loop expressions, templating, and customizing a pipeline according to user input. I started this project over a year ago, and over the course, I learned a lot about how Terraform works. Hopefully, some of our other Terraform friends would find this little tool useful! togomak is actually short for "to-go-and-make", and it sounds similar to "tokamak", a fusion device using magnetic fields to contain hot plasma for energy; perhaps it's containers here! https://ift.tt/05YDq78 October 24, 2023 at 11:19PM

Show HN: Glyph DLP – a data loss prevention API Hi HN, Glyph DLP is an API that scans or redacts sensitive information (emails, SSNs, credit cards, etc.) from Base64-encoded files/strings. So far I have coverage for text files, JSON, PDF, CSV, DOCX, and XLSX files and may consider adding a few more in the future. I made this app mostly for fun and learning and to scratch the creative itch over the past few months. I am using FastAPI in Docker hosting it on Fly.io. I originally wanted to use SQLite/LiteFS on Fly but ran into some issues with concurrent writers when keeping track of rate-limiting on the API. I am now using managed MySQL on Planetscale which has been awesome and would definitely recommend both Fly and Planetscale to anyone making small hobby projects. Even though the API functions are relatively simple, this is definitely the hardest I have worked on an app. I put a lot more effort into design and getting things how I want them, learning how to write better tests, documenting the API, etc. I also want to mention that Glyph DLP does not store any content from files as they are scanned/redacted or use the information from uploaded content in any way. I have no users to speak of at the moment and appreciate any feedback! https://ift.tt/t8dz9hr October 21, 2023 at 03:02AM

Show HN: Linkitall – create dependency-graphs of ideas What is the structure of knowledge? It's a broad question, and finding a structure that suits everyone is no easy task. Consider this: a backend developer might view knowledge as a table accessible with different keys, while a teacher might perceive it as a book, complete with chapters, sections, and subsections—a linear structure, yet with a tree-shaped Table of Contents for efficient reference. Generally, the structure we require depends on (a) the data involved and (b) the purpose at hand. Let's narrow it down: What's a suitable structure for teaching scientific knowledge? In the context of a specific course, one can assert that certain ideas are more fundamental than others. There's a hierarchy of ideas, where complex ideas build upon simpler ones, and those, in turn, rest on basic concepts. In simpler terms, with the exception of a few obvious or axiomatic ideas, every other idea relies on something else. Organizing all these ideas into a graph based on their dependency structure creates a dependency graph. Using graphical structure (including dependency graphs) to arrange ideas for presentation or teaching is nothing new. There are several tools out there, but none of them really worked for my use-case. So I wrote a tool in Golang which will take a graph definition in YAML format and produce a graph output in HTML. I am a noob in Golang. I am using python for work, so I wanted something else for this "hobby" project, and ended up with Go. This is the tool: https://ift.tt/kt7Gg4P Here are a few example outputs: Sets: https://ift.tt/XCTa2Ag... Trigonometric relations: https://ift.tt/XCTa2Ag... Note: one can click on the node name and it will open the associated slide. Kindly let me know what you fellows think. In particular, I would very much appreciate feedback from those in training/teaching/research background. https://ift.tt/kt7Gg4P October 19, 2023 at 04:40PM

Show HN: I made an all-in-one desktop app with a no-BS approach to get work done Hi HN! This is Daniel from Floutwork ( https://ift.tt/M1jKOZN ) Floutwork is an all-in-one desktop app designed to serve as a personal work system, offering a no-BS approach to getting real work done online. Background: When I transitioned from a development role to a product management role, I realized there was no real organization or structure to the way I worked as a PM. Tasks I needed to complete were scattered across emails, Teams, meetings, etc. I was inundated with emails and found myself juggling multiple browser windows, numerous open tabs, and other desktop applications. This overwhelming situation made it clear that success in my new role hinged on being self-organized and focused. After reading the book "Deep Work" by Cal Newport, I recognized that my work habits were counterproductive to accomplishing meaningful work. After that, I delved further into the "focus and productivity" path, read more books on the subject, and decided to integrate these concepts and methodologies into a single app. I could have created a specialized tool that addressed only one or two problems, like many other apps out there, but I knew that building a single app designed to assist with the workflow from start to finish was the only way to eliminate as many distractions and friction points as possible. Honestly, I could've wrapped up development way sooner if I'd just tackled one issue. But what's the point if one part of my workflow rocks and the rest sucks? What's the problem with modern work? You might be using a combination of a task manager and a calendar to track tasks. To work on a task, though, you probably bounce to your browser full of tabs. If you use desktop apps like Teams, Slack, or Discord, this bouncing back and forth becomes even worse because every link you click on opens in the browser. The real problem is when we jump to a browser full of tabs every time, we get distracted by all the tabs and get sidetracked, or our old habits kick in due to how our brains are now wired, and we start aimlessly browsing. This causes a lot of friction in our flow. This is one of the main reasons why people today are not able to focus or don't feel motivated to get work done. What usually takes 1 hour to complete can take up to 3 hours. What's unique about Floutwork? Floutwork has an excellent task management system and a calendar view right next to it to intelligently show you when you can work on your tasks amidst your busy schedule. However, it goes beyond that and lets you pin your work apps right within Floutwork. Once you know you need to work on a task, you can quickly hop on to your web apps right within Floutwork and get that done, and then repeat. Every time you access a web app within Floutwork, any tabs you open within that app stay within that app, so you only get to see the tabs to get your current task done. This powerful flow cuts down all the distractions and friction points that come between tasks and work getting done. Now that all your work can be consolidated into one unified system, you can access powerful tools in a distraction-free way to: - Monitor your work habits - Gamify your tasks - Experience an immersive focus mode for tasks - Open a command bar without losing your flow to open apps, links, tools, add tasks, ask ChatGPT, etc. - Quickly take work notes in context - Clean out your emails with a few clicks - Access AI tools via ChatGPT meaningfully right within your flow This app is designed for people in roles like PMs, freelancers, managers, admins, and marketers, where being self-organized online is crucial for success. I know the HN community has a lot of developers. While this app can offer some benefits to devs, it won't be a game-changer for your workflow, especially if you're primarily in VS Code or other desktop development tools most of the day. I'd love to invite you all to try out the product and would appreciate hearing your feedback! October 17, 2023 at 06:55PM

Using Web-LLM and Transformers.js to provide browser-based text-generation models on desktop and mobile, I built a minimalist self-hosted search app on which an AI analyses the results, comments on them and responds to your query summarising the info. In the backend, it still queries a real search engine, but besides that, there's no other remote connection happening. For running in the browser and on mobiles, lightweight models are required, so we can't expect them to give stellar answers, but there are a few advantages of using this over the services as mentioned earlier: - Availability: The AI will always be available and respond with the maximum available speed from the device. - Privacy: Besides the queries that go anonymously to the actual search engine, nothing else leaves your device. - No ads/trackers: Get the relevant links clean and fast without being tracked. - Customization: As it's open-source, you can fork it and re-style it any way you want. You can get started with MiniSearch by cloning the repository from GitHub ( https://ift.tt/L9SKtpw ) and running it locally or by using it online on this HugginFace Space: https://ift.tt/UvsuRPa (Alternative Space address: https://ift.tt/fzOmUTv ) You can even set it as your browser's address-bar search engine using the query pattern ` https://ift.tt/r7f9yu3 ` (where your query replaces %s). At the moment of this writing, the app is using TinyLlama and LaMini-Flan-T5 models, but there's an option to try to use larger models like Mistral 7B (not recommended, though, as it could be slow and break the fast-search experience). That's what I had to share. Thanks for reading! Your feedback means the world to me! Please don't hesitate to reach out if you have any questions or suggestions or want to learn more. https://ift.tt/fzOmUTv October 15, 2023 at 06:20AM
Show HN: OpenBLE, Swagger for Bluetooth OpenBLE is an API specification language and client generator for Bluetooth services built on the generic attribute (GATT) profile. Bluetooth development is a mess. Too many datasheets, too little documentation and SDK fragmentation across platforms. I built this tool to improve documentation, version control and development speed for BLE programs. Even though shunned by Apple and Mozilla, Web Bluetooth enjoys wide support and just works. It makes sense to build the frontend for OpenBLE using web Bluetooth. No SDK hell, no installations, wide support albeit experimental. I could ship the spec, SDK, code generator and testing framework in pure JavaScript. https://ift.tt/tdQig4N October 13, 2023 at 01:23AM

Show HN: thcon, a config-driven theme controller It's not the first CLI tool that switches terminal, editor, and desktop themes, and it certainly won't be the last. This one (mine) focuses more on switching between dark and light variants of a theme than on theme hopping, and is able to support a different set of tools. Notably, KDE Plasma, GNOME Shell user themes, and the macOS global dark mode are all supported, which is pretty unique I guess? https://thcon.app October 12, 2023 at 06:12AM
Show HN: A lightweight open-source web analytics for webdevs I wanted to share something I've been working on recently: Statum, a handy web analytics tool. https://ift.tt/Rfzrq0K The journey began when I found myself frequently needing simple web analytics for my projects. I tried Google Analytics, especially GA4, and realized it was quite complex and, at times, not very accurate, especially when I wanted to view stats for the current day or recent hours. Then I tested a few fancy startup solution but ended up with way too expensive plans the expect me to subscribe (I'm not that rich to pay $99/month for every pet project web analytics). This drove me to think, "Why not create a tool that bridges the gap between these complex/expensive platforms and the real needs of developers like me?" So, I designed Statum to seamlessly parse both Nginx and Apache server logs. It filters all necessary data, including IP, http method, URL, and user agent. What's more, it can categorize these user-agents into mobile users, bots, and others. Besides that...to provide a holistic view, Statum augments local log file statistics with web-based JavaScript analytics, offering even deeper insights, especially into returning visitors. With Statum, you can quickly get a grip on: - The number of visitors and a breakdown between bots and real users. - Identify visitors as unique entities (tied to the browser). - Client-side parameters such as screen resolution, OS, language. - Unique user-agents and much more. I've aimed to make the setup process straightforward (it's just one js line to insert into your website template and update a few paths in .py file to parse logs from the right place). Currently, it does not have UI, I use just a text output from sqlite, the default query to get the number of visitors and return visitors is in gen_stats.sh so you can enhance it depending on what you want to analyze. I'd appreciate any feedback you have on the project. Please keep in mind that this is an initial version and it's not designed for high-traffic websites. https://ift.tt/Rfzrq0K October 11, 2023 at 03:49AM

Show HN: CSSBattle – A competitive game for web designers and developers My name is Kushagra, and I am the co-founder of CSSBattle[1]. We built CSSBattle to make web designing a bit more fun. CSSBattle is an online competitive game where you have to replicate a given target image with CSS. When you submit your CSS code, you get a score based on how well you replicated the image + how short your code is. Our community has now grown to 320k+ players across the world. Over the past 3 years, we've been working hard to make it even more fun and educative for our players. I am very excited to show you a completely revamped version of CSSBattle with great new features which makes it the best frontend gaming platform on the web. Here's what's new: - Daily Targets: after talking to our users, we realized that not all players liked the pressure of leaderboards and competition. So we've introduced Daily Targets where players get a new target every day. These targets don't have leaderboards and are great for beginners who are just getting started - CSS Courses: We've also introduced game-like interactive courses for learning CSS - Monthly Battles: We now host monthly battles for players who crave competition. These are heated battles where players spend hours on shaving off a single character from their code just to rise up on the leaderboards! - Redesign: We've revamped the whole site to make it look nicer, and the whole experience smoother. We've also optimized it to work on mobile devices We would love it if you get a chance to check it out and are excited to hear all your feedback. Thank you for the support!

Show HN: A job application tracker with company reviews, recruiter autoresponder Hey folks. Rolepad is a product born out of my dissatisfaction with hiring processes - both as a candidate and as a hiring manager. Processes that are non-transparent, inefficient, and full of frustration for both sides. This early iteration has focused on the application tracking aspects with a few extra goodies. These days it is common to apply to dozens of positions (some users track over a hundred opportunities). Without a record-keeping system, it can quickly become an unmanageable mess. Even the better-organized among us often end up juggling spreadsheets, emails, and various notes. Rolepad was built to keep this data (company facts, role details, interview stages, contact info, freeform notes, follow-up actions, and more) in one place. Some of the other neat additions: - Forward emails to save@rolepad.com to save them as notes connected to specific opportunities. Forward recruiter messages to no@rolepad.com to have the system automatically reply with a decline response. - Generate shareable Sankey charts of your progress like this: https://ift.tt/QPAHt06 - Submit anonymous reviews and insights about application/interview/offer processes at a company . This is new and there aren’t great examples to share yet ( https://ift.tt/Ox6CpIY is an early glimpse), and I didn’t want to create fake data as a matter of principle. Oh yeah, and it’s totally free :) Creating an account is passwordless and takes seconds, but if you want to kick the tires even faster, I created test credentials for this occasion: username: test@rolepad.com password: hntest With this release, I am also starting conversations with employers ( https://ift.tt/PI48cSx ). A unified platform for candidates and employers can significantly reduce frustration for both in ways that email cannot. I should note that any solutions here have privacy implications and will require an exceedingly thoughtful execution. And now for the tech stack. The main application uses React with Tailwind on the frontend, C# on the backend, hosted in AWS (App Runner, Lambda, RDS Postgres, SES), with auth provided by Google Firebase, and CI/CD via GitHub Actions. The home page is actually an SSR (server-side rendered) application built with vite-plugin-ssr (now vike) and hosted in a Cloudflare Worker that hits the AWS-hosted API. This is basically a best-of-all-worlds SSR configuration - very fast, zero cold start (!), and essentially free. Any and all feedback is sincerely appreciated! https://rolepad.com October 6, 2023 at 09:31PM

Show HN: Cut back alcohol in a warm and supportive app I've always been a heavy drinker and tried multiple time to cut back alcohol, but failed every time. As a mobile developer, I had the idea to create a dedicated app to track alcohol consumption in quick and fun way. That's why I've developed Drylendar, an iOS app translated in French (I'm French) and English that allows people to track their drink every day in a beautiful calendar. To help people staying motivated, I've added medals to unlock and possibility to add friends to share calendars and positive energy. My app is available on App Store for 10 days, and it's been 215 days that I didn't drink alcohol at all, I've never felt healthier & happier! https://ift.tt/2Ea3Odx October 7, 2023 at 02:38AM

Show HN: Smartphone haptics for inducing calm, an alternative to meditation Hey HN, We've been working in neurotech over the past few years, primarily focusing on improving sleep. A friend asked if I would build her a vagal nerve stimulation device. These are devices used to improve relaxation, and “vagal tone”. She didn't want to shell out hundreds for the existing solutions. I originally said no, but then I thought, what if we leveraged smartphone haptics to achieve the same effect as these expensive devices? After some tinkering, Harbor: Immersive Calm was published to the app store last week. https://getharbor.app It’s pretty basic and very MVP, no logins, just: 1)open the app 2) select an immersion (mix of sound and haptics) 3) select how long you want to be immersed (?) 4) lay back, put your phone on your chest, and feel the sensations. In comparison to meditation, with Harbor, there is no “doing it right”, : Lay back, Tune In & Chill Out. I initially built for Android, but the fine-grained control and consistency of haptic motors in iOS device is a better experience. Though, I’m not ruling out a future dive into Android. Here’s a video demo( https://youtu.be/gr70kY9_Abk ) for a sneak peek. Though, without the haptic feedback, you can’t really get a feeling for the experience. Compared to devices the cost hundreds of dollars plus subscriptions, we’re thinking of a subscription model of $5/month. A friend who is a trauma therapist said she’d recommend it to some of her clients, and of course, there is the market of people who are looking to buy vagal nerve devices, and we can offer a lower cost alternative - and you don’t have to wait for shipping :) https://ift.tt/6DlRtrj October 6, 2023 at 12:58AM
Show HN: Dittofeed v0.5.0 – Self-host SMS and email customer messaging Hey HN, we’ve just released Dittofeed v0.5.0, with the primary change being the addition of SMS as a messaging channel. Dittofeed is an open source (MIT licensed) omnichannel customer engagement platform, similar to Customer.io and Iterable. We added: - Twilio-based SMS messaging. You can create SMS templates and customer journeys within Dittofeed. SMS is a great channel for B2C software companies, looking to engage with their users. For example, e-commerce businesses commonly use SMS to support checkout flows. We'll be making further enhancements to Dittofeed's SMS support in the coming weeks! - We added a new "Trait Exists" segmentation option, which can be used to create a segment of all users with phone numbers, for example. - We made some fairly large improvements to our settings UI.

Show HN: Running LLMs in one line of Python without Docker Hello Hacker News! We're Yangqing, Xiang and JJ from lepton.ai. We are building a platform to run any AI models as easy as writing local code, and to get your favorite models in minutes. It's like container for AI, but without the hassle of actually building a docker image. We built and contributed to some of the world's most popular AI software - PyTorch 1.0, ONNX, Caffe, etcd, Kubernetes, etc. We also managed hundreds of thousands of computers in our previous jobs. And we found that the AI software stack is usually unnecessarily complex - and we want to change that. Imagine if you are a developer who sees a good model on github, or HuggingFace. To make it a production ready service, the current solution usually requires you to build a docker image. But think about it - I have a few python code and a few python dependencies. That sounds like a huge overhead, right? lepton.ai is really a pythonic way to free you from such difficulties. You write a simple python scaffold around your PyTorch / TensorFlow code, and lepton launches it as a full-fledged service callable via python, javascript, or any language that understands OpenAPI. We use containers under the hood, but you don't need to worry about all the infrastructure nuts and bolts. One of the biggest challenge in AI is that it's really "all-stack": in addition to a plethora of models, AI applications usually involves GPUs, cloud infra, web services, DevOps, and SysOps. But we want you to focus on your job - and we take care of the rest "boring but essential" work. We're really excited we get to show this to you all! Please let us know your thoughts and questions in the comments. https://www.lepton.ai/ October 4, 2023 at 10:07PM

Show HN: Easy MQTT Handler – An MQTT Client to Connect Your PC to Home Assistant Hey HN. I wanted to share my pet project and first open-source contribution with everyone here! Here's a summary of what the tool does: The tool was mainly developed to provide an easy way to integrate Personal Computers into Home Automation and offers a simple, but functional, GUI to connect to an MQTT Broker and listen to a topic. The user is able to define commands and parameters that should be part of the payload of the MQTT messages received from the broker. For each command/parameter combination the user can then define an executable that should be launched once a certain command/parameter combination is received. The tool is neatly integrating into the users' environment by sitting in the tray area as a tray icon. It comes with a Qt5-based GUI and is licensed under the GPLv3+. If you have any questions about, just ask! Thanks. https://ift.tt/M5w1OI0 October 3, 2023 at 11:26PM
