Show HN: Bi-directional sync between Postgres and SQLite https://ift.tt/IzyUOsS

Show HN: Bi-directional sync between Postgres and SQLite Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is designed to be stack-agnostic. If you’d like to see a simple demo, check out the pebbles widget on the landing page here: https://ift.tt/XpA0hV9 We wrote about our architecture and design philosophy here: https://ift.tt/fseYyzC... This covers amongst other things how we designed the system for scalable dynamic partial replication, why we use a server authority architecture based on an event log instead of CRDTs for merging changes, and the approach to consistency. Our docs can be found here: https://ift.tt/EgRKjBJ We would love to hear your feedback! - Ralf, Conrad, Kobie, Phillip and team https://powersync.com November 30, 2023 at 07:43PM

Show HN: Domino – open-source GUI platform for creating data and AI workflows Domino is an open source platform dedicated to visually creating and managing data and AI workflows. The goal is for anyone to be able to effortlessly construct complex workflows by piecing together modular operators, no coding required! Additionally, Domino provides developers with a standard to bundle their Python functions into self-containing, reusable, shareable modules, that can be readily incorporated in the visual workflows. We've been working hard on this as a side project for a while, now we believe it has great potential to be used by the data / ML / Python community! https://ift.tt/qHgorWM November 29, 2023 at 10:42PM

Show HN: I built a fast, accurate translation API for 1/30th the price of Google https://ift.tt/CFwKSuX

Show HN: I built a fast, accurate translation API for 1/30th the price of Google Hey HN, I built an alternative to Google translate that's fast, accurate, and 1/30th the price. 20+ supported languages, not billed until 100k tokens, and already used thousands of times with real language learning users. The landing page has a demo for you to test performance yourself for free with no card required. (Also landing page says 1/13 the price because had to account for all 3 big names, with varying prices each). I built this as a workaround for my language learning startup, and it was perfect at a fraction of the cost. Hopefully it can help other devs in accessibility and language learning apps. Thanks, https://ift.tt/3sHCPeO November 29, 2023 at 08:19PM

Show HN: Dolt Workbench – A modern, browser-based, open source MySQL workbench Why are SQL workbenches stuck in 2002? I work for the company behind Dolt, the first fully versioned SQL database. As a database company, we have often felt the pain of the lack of modern, web-native or browser-based SQL workbench products. We built a cool database UI for our other web products (DoltHub and Hosted Dolt) and we wanted the world to have it. The Dolt Workbench not only works with Dolt, which will unlock version control features, but it also works with any MySQL-compatible database, including MySQL and MariaDB. As far as we can tell, the Dolt Workbench is the only free, open source, browser-based SQL workbench available today. We’re actively developing and would appreciate any feedback!

Show HN: Build an open-source computer vision model in seconds using text https://ift.tt/jlfQMYe

Show HN: Build an open-source computer vision model in seconds using text Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it work? We believe that with the rise of foundation vision models, computer vision will fundamentally change. These powerful models will let any devs “compile” a model ahead of time with a subset of the foundation model’s characteristics, using only text and a web-tool. The days of teams of MLEs building complex models and pipelines are ending. Zeroshot works by using two powerful pre-trained models, CLIP and DINOv2 together. The web-app allows users to quickly create our training sets via text search. Using pre-cached DINOv2 features, we generate a simple linear model that can be trained and deployed without any fine-tuning. Since you can see what’s going into your training set, you can tune your prompts to get the type of performance or detail you want. CLIP Small -- Size: 335 MB, Latency: 35ms CLIP Large -- Size: 891 MB, Latency: 276ms Zeroshot -- Size: 85 MB, Latency: 20ms What’s next? We wanna see how people use or would use the tool before deciding what to do next. On the list: clients for iOS and NodeJS, speeding up GPU inference times via TensorRT, offering larger Zeroshot models for better accuracy, easier results refining, support for bringing your own data lake, model refinement using GPT-V, we’ve got plenty of ideas. https://ift.tt/KTXMmWt November 29, 2023 at 01:48AM

Show HN: I built a domain name marketplace for folks (like me) who hoard domains Problem: I (accidentally) hoard domains :') 1. I get excited about a new project 2. I buy a domain 3. I get busy, and the domain collects a thick layer of dust I know I'm not alone in this, either So, I had the idea of creating a simple and casual marketplace for folks like me to list their domains at a fair price with a nice community feel to free up these caged domains It felt like a great project for me to pick up some new skills, so I got to it All up, it took me about a month, and I built the whole thing live on Twitch I've always sat on the design, marketing and front-end side of the fence, so this was my first attempt at making a 'full' web app Here's the stack I used: - SvelteKit ( https://kit.svelte.dev/ ) - Supabase ( https://supabase.com/ ) - Resend ( https://resend.com/ ) - ShadCN Svelte ( https://ift.tt/kxVwdpl ) It was super fun to build, and as a beginner, I learnt so much I leaned on AI quite heavily to help advance my speed of groking certain concepts within both SvelteKit & Supabase, and I blogged about the experience and my learnings here: https://ift.tt/HW9SgdE Any feedback/criticism very much welcome, I've got a lot to learn :) https://ift.tt/5FQGHzZ November 27, 2023 at 03:56AM

Show HN: I built a guided Build your own DNS Server challenge https://ift.tt/v7YUgZX

Show HN: I built a guided Build your own DNS Server challenge Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://ift.tt/VPmd648 I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project. At the end of the challenge, you will have created a DNS forwarding server. The server can create and read DNS packets and respond to DNS queries. As you go, you'll learn about the DNS protocol, its format, servers, and A records. All while getting to hone your language skills. Some of the challenges and choices I had to make: * To make the stages easier, I had to break them up, such that each step builds on the previous one. This was especially challenging for the 2nd stage, where we write a DNS packet's header contents. Even though I’d have liked it to be easier, breaking it up further would have been weird. * Instead of implementing a recursive resolver, I've restricted to a forwarding server. We made this decision so that most developers can still use it. To add more complexity, we can use a challenge extension (noted below). * Deciding how much instruction and context the stages should provide. I’ve decided to keep them as thorough as possible for most of the stages. Developers can choose to have thorough details or just skim through them. I would love your feedback and questions on the challenge. You can try it out for free here: https://ift.tt/VPmd648 (no CC required). I also have challenge extensions planned. You can find them at https://ift.tt/q0NgSY3... . I'm also keen to hear what you think about the extension ideas. https://ift.tt/XSOqNwU November 27, 2023 at 12:06PM

Show HN: I Wrote a Book on PostgreSQL for Rails https://ift.tt/MZHbKuX

Show HN: I Wrote a Book on PostgreSQL for Rails Hi HN. As a backend developer using PostgreSQL and Ruby on Rails for more than 10 years, around 3 years ago, I caught a spark to learn as much as I could about how to operate high performance, scalable, and reliable PostgreSQL databases. As I reflected on my own career path, I realized there are other developers that may want to learn more about this. I saw an opportunity to help show backend developers how they could put advanced, powerful, PostgreSQL features to use, to help build and scale their Rails apps. I've been fortunate to give presentations in both the PostgreSQL and Rails communities over the last couple of years. In that time I've continued to work with these technologies every day. With that said, I'd love for you to check out my new book: "High Performance PostgreSQL for Rails". Currently in ebook/PDF Beta form. While it's only an ebook for now, there's an expected physical version coming in early 2024. Today you can pick up the PDF/ebook version for 40% off using code: turkeysale2023 There are free PDF excerpts you can check out, to see if this book is for you, or something you'd recommend to others. The book is currently on the weekly Best Seller list at Pragmatic Programmers, where it's appeared several times in the last couple of months. The book focuses exclusively on open source software like PostgreSQL and Ruby on Rails, adding more than 40 Ruby gems and PostgreSQL extensions into the stack of tools. The Rails application used throughout the book is available on GitHub. Whether you work with Rails or another similar MVC full-stack framework or ORM like Laravel, Django, or Prisma, I hope there’s something useful in the book for you or your colleagues. I love writing, learning, and sharing, and advocating for PostgreSQL and Ruby on Rails! Thanks for your support! https://ift.tt/F04d8xi November 25, 2023 at 01:29AM

Show HN: UI Library Creator https://ift.tt/Uf3deAH

Show HN: UI Library Creator Hey HN! The "Generative" trend is booming, and UI Library Creator is our original approach to it. In the last three years, we have added 60+ professional UI libraries to Shuffle's catalog (Shuffle = visual editor for web developers). Still, we know we need more than this to satisfy our growing user base! That's why we created the UI Library Creator. In this tool, you can combine elements and styles to create unique UI libraries that work seamlessly with the Shuffle Editor and all its capabilities (drag-and-drop, customizations, live preview, and more). We provide you with UX solutions (components) written in Tailwind CSS and presets so you can quickly combine them to create what you need. You don't need to talk to a "black box" AI with a chat interface. Possible combinations are in gazillions. We aim for original creations, but you have complete control over the final effect. How to use the UI Library Creator: * Visit: https://ift.tt/dW6Agyr * We recommend starting by selecting Assets and Copywriting for your target audience. * When these two options are locked, use the "Shuffle Styles" button to bootstrap your project with the first style. * If you like something, lock the category and then repeat shuffling. You can also change options manually, but with "Shuffle Styles," you can quickly see many creations. If you enjoy the final result, click "Publish now" and send your UI Library to Shuffle. Once processed, it will be available for use in your Dashboard. Let us know what you think!

Be warned that it's in single user, so nothing is private! ---- Last week I came down with a fever and decided to run some experiments on whether the new GPT could generate long-form fiction. Around the same time, I saw a HN comment about how technology gains have lead SWEs to work at higher levels of abstraction—and I thought “huh, why not writers?” Anyway so I was locked indoors for a week and a half and I spent it coding an answer that question. Most of the magic sauce here is just in making it feel really snappy and good to edit—making it easy for the human to collaborate with the objectively faster LLM. The underlying prompt engineering is cool, but it’s the feeling that you can do more than just shoot a prompt at ChatGPT and hope for a good result, or start writing and hope for a good autocomplete. Definitely gave me some ideas for future LLM experiences I want to try out, let me know what you think! https://ift.tt/CSliaJk November 23, 2023 at 03:41AM

Show HN: Gaming Gaiden: A lightweight gaming time tracker in PowerShell https://ift.tt/v8XVnUz

Show HN: Gaming Gaiden: A lightweight gaming time tracker in PowerShell Hi Everyone, I made a Powershell application to track time spent playing pc / emulated games. It provides many other interesting statistics as well over long term that can add value to someone's gaming hobby imo. I used to use a closed source program called Gameplay Time Tracker for time tracking focused on gaming, but overtime it started failing and throwing exceptions everywhere. I tried reaching to its Developer to ask if they can open source it and i can fix the problems. I couldn't raise them. It had been truly abandoned. After a while i just decided to build a replacement. Few choices that may seem strange, using Powershell for a GUI application, building the GUI with HTML, CSS and JS instead of native windows forms. All of these were made because i am not a windows app dev / GUI dev. I am infra engineer and have strong scripting skills. Instead of getting bogged down in learning a whole programming language like C# and .Net., decided to go with Powershell. DataTables and ChartJs made it trivial to create the UI. Pragmatic choices over conventional wisdom basically. It turned out well in my opinion. Got some attention on reddit and in a youtube channel. Thought it would be good to share here as well. https://ift.tt/yAsv82l November 21, 2023 at 11:10PM

Show HN: Bemi – data versioning and time travel for PostgreSQL https://ift.tt/lvUg5iw

Show HN: Bemi – data versioning and time travel for PostgreSQL Hi HN, we’re Evgeny, Arjun, and Donna - the builders of Bemi ( https://bemi.io ). Bemi is an enhancement of your existing transactional database to unlock time travel querying. We enable engineers to track all PostgreSQL state changes. We used to all work together at a startup five years ago, and now have got the gang back together to work on Bemi! Many open-source libraries already track data changes, but they’re not reliable since they don’t track changes made outside ORMs with direct SQL queries. Additionally, they come with runtime performance overhead since they’re making database inserts in callbacks. We’ve also consistently seen hacks that engineers write on top of the libraries to store additional context or make it easier for them to query. There are databases already available for event sourcing, but we take a fundamentally different approach. We don’t want engineers to have to rearchitect their existing code, switch to highly specialized databases, or use unnecessary git-like abstractions. We want your system to work the way it already does with your existing database to allow keeping things as simple as possible. Bemi uses change data capture (CDC) by connecting to a built-in replication log of a database, ingesting all changes on the database level, and storing them in a structured format in a destination database. The database connection details can be securely configured through our dashboard UI in a few seconds. People also try adding database triggers to track low-level data change. The main difference is that Bemi integrates not just on the database level, but also on the application level with packages in the most popular frameworks (being released soon) and a Bemi worker automatically stitches application metadata with the lower-level change data to get the “where” (API endpoint, worker, and so on) and “who” (user, cron job, and so on) behind a change.

Show HN: Beta test Execute Program's interactive "Python for Programmers" course https://ift.tt/62KxmYu

Show HN: Beta test Execute Program's interactive "Python for Programmers" course I'm Gary Bernhardt, founder of Execute Program. Our "Python for Programmers" course is in a free open beta for the next week or so. We don't normally do open betas, but the infrastructure behind this course is new and very complex, so we want to stress test it. https://ift.tt/al71Wj5... Today, "Python for Programmers" contains 581 interactive code examples covering the core language. It's aimed at established programmers, not beginners. We don't explain basic language features like `while`, but we do show them briefly and note anything special about how they work in Python. We pay special attention to foot guns. For example, we have an entire lesson about Python's mutable default argument foot gun. This is the first of two courses, with the second coming in 2024. For this course, we drew the line at __dunder__ methods: if a topic requires a dunder method other than `__init__`, then it'll be in the follow-up course. This beta is concurrent with the tail end of our editing process, so you may see the course grow by another 17 lessons (214 code examples) during the beta. Some details about how the course works internally, and why we need a beta at all: First, all Python code in the course runs in your browser via Pyodide. (Reality continues to look more and more like my PyCon 2014 talk [1].) You'll feel a pause when the first code example runs, as your browser loads and boots CPython (around 12 MB). After that, it should be as responsive as a local app. Second, if you look at the course page, you'll see that it's structured as a DAG, similar to a "tech tree" in Civilization, Age of Empires, Stellaris, Satisfactory, etc. (Some of those games have true trees, but some of their "trees" are actually DAGs like ours.) You make progress through the course by traversing one graph edge at a time. Our courses have always been structured as graphs internally, but the raw graphs are simply unreadable due to the number of edges [2]. This year, I taught Execute Program to simplify its own course graphs by breaking them into the level subgraphs that you see on the page, so we can finally render them. It automatically turns the mess that I linked above into the clean graphs that you see in the course. The graph for this course is currently a bit dull, but it'll fill out as we finish editing the remaining lessons. I like Everyday TypeScript's graph [3] the best. Please try the course and use the "Give Feedback" entry in the menu to tell us what you think! I'll also stick around in this thread today. [1] https://ift.tt/hGqvaQr... [2] https://ift.tt/JuP81p5...

Show HN: Version code, models, & datasets together in GitHub https://ift.tt/4RzKLag

Show HN: Version code, models, & datasets together in GitHub Hi HN! We just launched a GitHub integration that scales your Git repos to handle 100 terabytes of files in a single repo. XetData enables data scientists and machine learning engineers to version code, models, and datasets together. Most teams have glued together clunky workflows using S3, DVC, Git, Git LFS, and other tools and make true reproducibility difficult: https://ift.tt/U6QEl4w We instead embrace and extend Git so end-users don’t need to learn a new tool and a new set of commands. Our implementation is similar to Git LFS, where we take over the .gitattributes file, push pointers to large files in GitHub, and push the raw, large files to us. We have a few distinct features that we’re proud of that improve the user experience: - Our XetData bot comments on your pull requests to provide links to useful dataset views and model diffs. We’re working on rendering these inside GitHub itself using browser extensions. - Git LFS and similar tools only implement file-level deduplication. We created a new technique called block-based deduplication (published in CIDR’23 conference) specifically for data and ML workflows. The ML lifecycle consists of making lots of iterative changes and our technique helps save storage and time spent downloading and uploading changes. - You can mount large repos to your local machine using git-xet mount for exploratory work. Individual files that are needed are streamed in just in time behind the scenes. We open sourced our implementation of mount and it was well received here on HN: https://ift.tt/X5YkjC7 - To give more users access to your data, just add them to your GitHub repo. This is a beta product and we would love all of your feedback. You can find all instructions to try this out here: https://ift.tt/uIPyvaV While we’re in beta, our product is completely free to use. We have a Slack you can join or a GitHub issue tracker. - Slack: https://ift.tt/l2krcJt - GitHub: https://ift.tt/JnU7bzG November 16, 2023 at 11:56PM

Tracking is an important topic, closely related to object detection. However, I've noticed that it doesn't receive as much attention compared to machine learning approaches. Or, the focus is on filters like the Kalman filter. This tutorial begins with single object tracking and progressively complicates the tasks, introducing various models and a hypothesis tree to solve them. https://ift.tt/4swoFOJ November 16, 2023 at 12:06AM

Show HN: Movis – A Video Editing Library in Python Originally, this library was created due to my motivation to make videos in Python. Of course, I considered other Python libraries, but I decided to create a new library for video editing because I needed the following features and also for study purposes: - The existence of composition. Especially, the ability to perform advanced video editing by inserting compositions within compositions. - The ability to add animations based on keyframes. - Effects like chroma key and drop shadow. - A caching mechanism to render the same frame quickly. - Various blending modes. These features, despite being standard in proprietary video editing software, were not present in previous Python libraries. Currently, I am using this library to automatically generate videos from raw materials. I would be grateful for any comments, thoughts, or requests. https://ift.tt/79oD0qX November 15, 2023 at 10:50PM

Show HN: Twogether AI – Multi-Person Photo Generation API https://ift.tt/iMdpJcj

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/fM6tdIq (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/GyTZnsv November 13, 2023 at 08:37PM

Show HN: Bitemporal, Binary JSON Database System and Event Store https://ift.tt/VxvGpyk

Show HN: Bitemporal, Binary JSON Database System 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 LinkedIn profile" for better networking/job hunting https://ift.tt/JjDT0N7

Show HN: "Interactive LinkedIn profile" 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/hVgLKP8 November 13, 2023 at 06:14AM

Show HN: Docker Swarm Multi Tenant Proxy https://ift.tt/Hy3Danl

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/lWuDb1x November 13, 2023 at 12:45AM

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/dKJmbRU 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/y9SkJcC ), 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.

Then I indexed the vectors using hnswlib ( https://ift.tt/8AFxvzC ). 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/recRZxQ November 10, 2023 at 01:05AM

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

There are already some tools that render flamegraphs for java, but they are focused on measuring performance or require some other process running along with the application. They also record function calls, but do not record the arguments or return values from those functions. I needed instead something to help understand and debug my applications that was better than adding breakpoints and slowly step over every call. This is a simple java agent that renders a flamegraph on a html file, no extra dependencies or other processes involved. All you need is an extra argument passed to the JVM on the command line pointing to the java agent. It calls toString on every parameter and return value of every function that is included on the filter, so I wouldn't use this outside your dev machine. https://ift.tt/4Mewv0K November 8, 2023 at 04:39AM

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework https://ift.tt/5Lt8izA

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/JFY05oZ November 5, 2023 at 12:03AM

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth https://ift.tt/fzrAk5Q

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth Hi there! This is Yury, a co-founder. We've been busy for a while building EdgeDB Cloud and now it's finally here. EdgeDB Cloud is pretty cool and takes full advantage of our database. You get declarative schema, strict typing throughout, great performance, a query language that's best of GraphQL & SQL, and many many other perks. The Cloud itself is quite unique because of EdgeDB. Our query language gives you composability - so you can fetch everything for your page or API endpoint in one network request. And our protocol and client libraries give you auto recovery on network errors, automatic transaction retry, built-in transparent connection pooling, and many other benefits. Check out the blog post where we explain it all. And watch the currently ongoing YouTube Premiere of the launch! https://ift.tt/lyxG9q3 November 1, 2023 at 10:57PM
