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!

Show HN: Cyberkitty – an experimental hybrid-GPT+Human long-form fiction editor NOTE: If you're one of the first people to see this, you can also access a running installation at https://cyberkitty.ai It'll run until I hit my GPT-4 budget limit, then stop working. 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: "Awesome" Engineering Games (List) I've spent way too much time both playing and finding engineering-focused games, and haven't been able to find very detailed or comprehensive lists online. So I made one :) These games are both fun and often quite educational, presenting gamified versions of real-world challenges and professions. There's a lot of different sub-genres of "engineering game", such as: * Factory automation (Factorio, Dyson Sphere Program) * City builders (Cities: Skylines, Anno series) * Route-builders (Mini Motorways, Railway Empire) * Comp sci (TIS-100, Bitburner) All games on the list are very highly reviewed. I've played most (but not all) of them, and provided personal recommendations alongside the reviews. Many of them are also playable on GeForce Now (if you don't have a gaming PC). Please contribute if you know of more, or have any comments/suggestions! https://ift.tt/eULx6Ya November 20, 2023 at 12:52AM

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. This allows being able to revert all data changes made within an API request, for example. For the sake of transparency, we intend to make money by implementing usage-based pricing and a multi-cloud hosted option. Bemi’s free for early adopters. We are still early though and would love your feedback. What do you think HN? https://bemi.io/ November 17, 2023 at 09:42PM

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 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

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.

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

Show HN: OP-A, a GPT that is a synthesizer https://ift.tt/E8B3LNh

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/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. I vectorised the films using Hugging Face's T5 model ( https://ift.tt/k67daCr ) using the film's plot synopsis, genres and languages. 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

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: 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: Javaflame – Simple Flamegraph for your Java application https://ift.tt/Kw1kPQT

Show HN: Javaflame – Simple Flamegraph for your Java application Javaflame will generate a flamegraph of your application function calls, including the argument values and the return of each function. Check https://ift.tt/fCNxtkX to see an example. 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 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

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/TQtpC14 October 31, 2023 at 10:12PM

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.

But actually in real world, if you take server and CDNs into consideration, 8k seems to be a de facto limit ( https://ift.tt/X0udlmn ), still enough for usual todo lists :) Previous discussions on HN about saving data in URL, https://ift.tt/zSc5vdn , https://ift.tt/kGnXTPl , https://ift.tt/GO4UPs3 https://2doli.st/ November 1, 2023 at 03:10AM

Show HN: Unlogged (YC S22) – open-source record and replay for Java https://ift.tt/xi52ezv

Show HN: Unlogged (YC S22) – 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/hz26fNE 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/HOrh6Uv We are excited to launch the first version of our product that replays with assertions + mocking + code coverage reports right inside the IDE.

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: Launch a private Ethereum Testnet with all clients and MEV infra https://ift.tt/E10xuAN

Show HN: Launch a private Ethereum Testnet with all clients and MEV infra We've been working with the Ethereum Foundation & Flashbots to build tooling and infrastructure for developers to test various workflows for Ethereum. As part of that work, anyone can now spin up a local Ethereum dev net with the entire Flashbots mev-boost infra (relayer, builder, boost) using the ethereum-package. This package supports all EL and CL client types, works on Kubernetes for scale testing, and comes with a few bells and whistles like metrics, mock-builders, and beacon chain explorers. This is the de-facto tool for teams modifying and testing the consensus layer. Here's a full tutorial - https://ift.tt/pvo2wUe... https://ift.tt/S1pjb2H October 30, 2023 at 11:22PM

Show HN: Newslater – A Personal Newsletter Generator https://ift.tt/m7uPlBp

Show HN: Newslater – A Personal Newsletter Generator Inspired by my ability to collect articles from HN that I wanted to read, but never getting around to reading them, I built Newslater. You add the articles you want to read to your reading list, and Newslater will email you a newsletter containing summaries of 5 of your articles sent at a time you choose. My aim was to create a tl;dr newsletter from articles you are actually interested in. The app is free, has no ads, and is available on Android and iOS: https://ift.tt/J5nbshD https://ift.tt/xFA9bYy It’s a bit rough, but I thought some others may be interested in giving it a go. You can see examples of the newsletters it generates here too https://newslater.co/ October 29, 2023 at 09:33PM

Show HN: Mify – CLI that generates and maintains your backend infra code https://ift.tt/4INU2Y6

Show HN: Mify – CLI that generates and maintains your backend infra code Hello, for the past couple of months, we've been developing Mify and I wanted to share it with the people here. We've been writing backends for multiple different big and small companies and noticed that backend development progresses in way too similar cycles. At first people write a small set of services or in better case a single service to do what's needed. At some point the tech debt becomes too much of a hassle to handle as company grows, engineers are starting to scale the codebase, rewriting code, splitting monolith, introducing microservices and eventually after a bunch of iterations like that, people write some sort of in-house internal developer platform to quickly spin up services. The amount of effort it takes to go through this is really unnecessary. Every team needs to get a bunch of libraries for storage, configuration, logging, metrics, etc and duct tape them all together until it works, then write boilerplate for all of that, and then there's also infrastructure code and configs to set up deployment. So, we think that it doesn't have to be that way and that's why we wrote Mify, which is an open-source tool that generated and maintains all boilerplate code for the necessary building blocks of a backend service and help with deployment. Even at this early stage Mify can save a lot of development time, so check it out, we would appreciate your feedback! https://ift.tt/9sxScyH October 30, 2023 at 01:29AM

Show HN: Yet another HN UI clone (sorry) https://ift.tt/TAIt0hY

Show HN: Yet another HN UI clone (sorry) Inspired by https://ift.tt/ThUAkYg , this is done sort of as a learning journey since I've never built an app from scratch using Next.js and tailwindcss before. This is done over 2 days so it's quite bare in terms of features i.e. read-only but I would still like to share this project. Let me know what you guys think and feel free to provide any feedback! https://ift.tt/gN2Duod October 29, 2023 at 11:13PM

Show HN: A local Python prototyping tool for Jupyter and Streamlit https://ift.tt/zq5KbZc

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/NSuFMEx October 27, 2023 at 08:04PM

Show HN: FreeChat – local LLM chat for macOS https://ift.tt/RrhTbGd

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/kaBm28M October 26, 2023 at 02:30AM
