Show HN: A Modern Palletization App
6 by vld5 | 0 comments on Hacker News.
When searching on the internet for these type of apps, I didn't find many that were open-source AND easy to use. A lot of them had complicated interfaces, although they had loads of features as well. So what I had in mind when making Stack Solver was an app with a modern interface that has the most essential features. It is also well integrated with Microsoft Excel and renders a 3D customizable drawing. Stack Solver is programmed in C# using the WPF framework to ensure it is fast and light. The interface is built using WPF UI, a library that allows it to keep up with modern trends (specifically the Fluent design). It is a work in progress with tons of new features planned and it is my first "serious" project so I would appreciate any feedback :)

Show HN: Lambda – The first-ever open-source privacy based social media app
2 by Ezpie | 0 comments on Hacker News.
Hi HN community! NOTE: This is a repost due to missing of links I’m excited to introduce Lambda, a project I've been working on. Lambda is the world's first open-source social media app designed to prioritize your privacy and well-being. It's still in its early stages, but I'm eager to share it with you and get your feedback. What is Lambda? Lambda is an open-source social media app that addresses privacy concerns and reduces social media addiction. Here's what makes Lambda unique: - Privacy First: Lambda does not collect personal information beyond your email address for account creation. Your data is yours alone. - Organic Feed: No AI-generated feeds or targeted advertisements. You only see posts from users you follow. - Open Source: Built-in public, with community feedback and contributions highly encouraged. What's Next? Currently, Lambda is a basic version with text-only posts. Here are some things I’m working on: - Adding support for images and videos - Reducing latency - Enhancing the overall user experience You can check out Lambda and create an account here[ https://ift.tt/2GNAgdn ]. Feel free to explore, and I’d love to hear your thoughts and suggestions here[ https://ift.tt/oF6NmnK... ] GitHub Repository If you're interested in contributing or just curious about the code, you can find the repository here[ https://ift.tt/DjhybLI ]. A star on GitHub would be... private... I am not a comedian. Feedback I’m around to discuss and answer any questions you might have, you can always jump over to GitHub discussion[ https://ift.tt/oF6NmnK... ] and drop feedback there. Your feedback is extremely valuable, and I'm looking forward to improving Lambda with the help of the HN community. Thanks for taking the time to check out Lambda! Best regards, EzpieCo(not my real name)

Show HN: pypiscout.com – Find packages on PyPI with natural language queries
2 by flo12392 | 0 comments on Hacker News.
Finding the right Python package on PyPI can be a bit difficult, since PyPI isn't really designed for discovering packages easily. For example, you can search for the word "plot" and get a list of hundreds of packages that contain the word "plot" in seemingly random order. Inspired by [this blog post]( https://ift.tt/Gs0h7yP ) about finding arXiv articles using vector embeddings, I decided to build a small application that helps you find Python packages with a similar approach. For example, you can ask it "I want to make nice plots and visualizations", and it will provide you with a short list of packages that can help you with that. You can try it out at https://pypiscout.com

Show HN: Scene-AI powered all-in-one web design workspace
2 by jhozeek | 0 comments on Hacker News.
Hey everyone! Excited to share Scene with you! We spent hours investigating the intricacies of how people create websites. We focussed primarily on collaboration: what it looks like when teammates with different areas of expertise work together to build a site. We did a deep dive into how designers and marketers work today, and how they envision working in the future. AI will be a big part of that future. But AI is not here to replace the web design process. We know designers don't fully trust creations made entirely by AI—and why should they? Instead, AI is here to lend a helping hand. It can help you get past the ‘blank canvas’ stage with suggestions, and level up your creative ideas. We'd like your feedback on these two key areas: Collab - Scene is designed to help team members work together, making it easier to share ideas, provide feedback, and iterate quickly. We’re eager to learn more about how you currently collaborate on projects. Muse - Our AI tool isn’t just about automation; it’s about augmentation. We aim to complement your creativity, not replace it. How do you envision AI supporting your workflow?

Show HN: I Built a Tool to Break Free from YouTube's Addictive Algorithm
2 by sarmadgulzar | 0 comments on Hacker News.
I built Watchlist to solve a problem that's been nagging at me (and I suspect many others): YouTube's addictive nature and its impact on productivity. The Problem: YouTube is an incredible source of knowledge, but its homepage is an unending scroll of rabbit holes. The algorithm is designed to maximize watch time, often at the expense of our intentions and productivity. I found myself wasting hours, jumping from video to video, and then blaming myself for the lack of self-control. The Solution: Watchlist! Watchlist is essentially YouTube playlists on steroids. Here's how it works: 1. Create custom "lists" for different topics (e.g., AI, Science, Programming) 2. Add relevant channels to each list 3. Watchlist automatically adds new uploads from these channels to your lists 4. Set custom notification schedules for each list (e.g., every morning at 8 AM, every Sunday at 5 PM) 5. Receive email or push notifications (your choice) when there are new unwatched videos The result? You stay updated on the content you care about without falling into the YouTube homepage trap. Tech Stack: Built with Python, JavaScript, Supabase & Google Cloud Run. (Took six weeks) Why I Built This: As an electrical engineer turned software developer, I've always been fascinated by programming. This project combines my love for coding with a real-world problem I've experienced firsthand. Try It Out: To make it as easy as possible for you to try Watchlist, I've set up a 1-click dummy login: https://ift.tt/xIbl4m1 This generates a dummy email and password for you, valid for 14 days. Although this account has full access, please note some restrictions: - You cannot reset the password - Email notifications are disabled - Data cannot be migrated to another account - The account will be deactivated after 14 days For those who prefer a proper account, you can register normally at: https://ift.tt/HiDIKN8 Feedback: I've seen many people struggle with YouTube addiction without realizing the root cause. If you've faced similar issues or have thoughts on this approach, I'd love to hear your feedback. Your thoughts and suggestions are crucial for improving Watchlist. There's a dedicated feedback page at: https://ift.tt/9BNve87 I'm eager to hear your experiences and ideas! Thanks! PS: This is my first Show HN. So, please excuse me if I made any mistakes. I tried my best to follow the guidelines.

Show HN: Envelope – A modern environment variable cli tool
3 by mattrighetti | 3 comments on Hacker News.
Hey HN! I've built this cli tool to manage env variables of a project, but mostly for fun and to try out Rust and the clap crate. I had this idea when I made a big mistake and broke some production stuff because I had a very messy .env file laying around in my project. I was implementing new features for one of my projects and in my .env file I had the test database url commented out and the production one was not. Long story short, I applied migrations to the production database instead of my local test one and broke a lot of production APIs :') I wanted a tool that could easily help me spot these issues before something bad happened, and so I built envelope for that reason. Instead of a \.env(\..+)? file, I now use this tool to add variables to different configurations: dev, prod etc. and I feed them to the program I am executing on a one liner. $ envelope init $ envelope add dev db_url localhost:5432/postgres $ envelope add dev db_username username $ envelope add dev db_pwd pwd $ export $(envelope list dev) $ ./run.sh This way I am explicitly exporting the dev environment without relying on the fact that everything is in order in my .env file (another approach would be to have a .env.dev file) A very useful feature that I use quite a lot is the `check` command which is going to tell you which environment you have currently active $ export $(envelope list dev) $ envelope check > dev I don't think this tool is going to be useful to anybody, but I wanted to share this with you in case there is someone that can make good use of it or find particular scenarios where this could be used instead of .env files, either way I had a lot of fun building it

Show HN: Lady Deirdre 2 – Rust Framework for Compilers and LSP Servers
2 by Eliah_Lakhin | 0 comments on Hacker News.
Greetings! I would like to share with you my project, Lady Deirdre. Lady Deirdre is a framework that helps you create new programming languages in Rust. It is specifically designed to develop compilers and interpreters with support for code editor extensions (LSP servers) from day one. The framework includes essential components to design parsers and semantic analyzers capable of incrementally reparsing dynamically evolving source code. Lady Deirdre can be seen as a replacement for preexisting projects with similar goals, such as Tree-Sitter, Rowan, or Salsa. However, Lady Deirdre aims to offer a unified framework API that guides you through the steps of programming language development, providing even more components necessary to develop a full-featured language ecosystem. For example, components to develop a source code formatter. I will be happy to answer any questions. Ilya

Show HN: I Built a Non-AI Platform for Verified Deployment Scripts
2 by superjose | 0 comments on Hacker News.
I'm a solopreneur who has bootstrapped five tech startups over the last 10 years (all of them have failed). I've hated the time I've spent uploading the apps... Jesus Christ! A couple of months back, I spent 21.4 hours trying to configure a minimum-permission automated deployment script with Docker, Go, and Cloud Run. It was my first time with Google Cloud Run (I have past experience with AWS - EC2, SQS, DynamoDB, etc.). I remember fighting long days to set up AWS… But it happened again with GCP: 1. Fragmented documentation 2. Lack of examples 3. Strange, obtuse errors 4. Setting up service accounts was a nightmare. No wonder people go for admin rights and call it a day. 5. ChatGPT and Gemini were dancing around like headless chickens. No wonder wrapper services like Vercel are successful. But, I don't want wrapper services: - They don't have what I need - They can become very expensive - They don't give me control of the services I need (Escape Hatches) Seeing this gap, I'm sharing a platform that does things differently: - You manage your infrastructure (connect directly to the cloud provider) - Infrastructure code with tools like Pulumi is created for you. 100% verified.

I'm a solopreneur who has bootstrapped five tech startups over the last 10 years (all of them have failed). I've hated the time I've spent uploading the apps... Jesus Christ! A couple of months back, I spent 21.4 hours trying to configure a minimum-permission automated deployment script with Docker, Go, and Cloud Run. It was my first time with Google Cloud Run (I have past experience with AWS - EC2, SQS, DynamoDB, etc.). I remember fighting long days to set up AWS… But it happened again with GCP: 1. Fragmented documentation 2. Lack of examples 3. Strange, obtuse errors 4. Setting up service accounts was a nightmare. No wonder people go for admin rights and call it a day. 5. ChatGPT and Gemini were dancing around like headless chickens. No wonder wrapper services like Vercel are successful. But, I don't want wrapper services: - They don't have what I need - They can become very expensive - They don't give me control of the services I need (Escape Hatches) Seeing this gap, I'm sharing a platform that does things differently: - You manage your infrastructure (connect directly to the cloud provider) - Infrastructure code with tools like Pulumi is created for you. 100% verified. No AI hallucinations or sorcery. - Service accounts are created for you with minimum permissions - Pulumi is set up for you, connected with the deployment keys - The infrastructure will have all the dependent services chained together in the right order - It's idempotent.

One of my biggest issues of switching to Firefox was the lack of quick tab navigation. So, I scratched my own itch and made this thing. Been using it myself for months and it has been working great.

I've been playing around with ESP32 MCUs and displays for a while and finally got around to getting a ZX Spectrum emulator working. I then saw that you can now do full color silk screen printing on PCBs and got the thinking - the ESP32 has capacitive touch capabilities - I could make a full ZX Spectrum keyboard on a PCB along with all the electronics for running the emulator. And it actually works! There's a full video here: https://youtu.be/foP81O48WAI And you can sign up here for updates as I move towards getting it ready for a production run: https://ift.tt/nArCwa7... It's looks amazing, takes me back to my childhood.

Show HN: Ritt – The tag-centric file manager
2 by chenxy88 | 0 comments on Hacker News.
Hello HN! I am very excited to introduce Ritt, the tag-centric file manager. Tags are excellent for managing images, videos and documents, yet most file managers implement tagging functionalities as an afterthought. Not so with Ritt. Ritt is an acronym for Representation of Independent Tag Trees. As the name suggests, tags are front and center in Ritt. Ritt is designed to allow for fast and efficient batch tagging of files (and folders). Drill down to your desired files by intersecting and/or excluding tags. Other features include: - Sync tags across machines - Advanced search by combining tags using logical operations - Create links and backlinks between local files and folders - Auto Tag image files with AI - Powerful built-in previewer, hover over video to scrub - Create tasks within folders If you have any comments or suggestions for new features, please do not hesitate to let me know!

Show HN: kankan, infinitely nested kanbans for procrastinators
3 by lagt_t | 0 comments on Hacker News.
Every time I tried to organize my life I always found myself on the receiving end of the same three problems: - Overwhelmed by the volume. - Discouraged by the effort required. - Frustrated by lack of progress. I always liked how kanban boards worked on my job, but when trying to translate them to my personal life they got too big and unwieldy fast. I figured out that if I made them infinitely nestable I could solve the 3 problems at once - Being able to break down the tasks into smaller and smaller subtasks until the activation cost didn't discourage me. - Hiding the total volume in that nesting dimension, I can have more focused visibility and avoid being overwhelmed by the volume. - Tracking even the most minimal progress kept me motivated as I had immediate feedback that my effort wasn't in vain. Here's the URL: https://kankan.quest It's free and open source. Currently working on multi language support. Feedback is appreciated. Enjoy!

Show HN: b2v.xyz – Protection against impersonation attacks
4 by b2v | 0 comments on Hacker News.
Hi HN, I’m the founder of https://b2v.xyz , a service that protects organizations against impersonation attacks. The problem I’m trying to solve stems from the following observation: while end-user authentication methods are becoming more advanced as cybersecurity evolves, organizations aren't experiencing the same improvements when we reverse the roles, i.e. when organizations authenticate themselves to their users. This imbalance leaves a gap in secure communications that B2V aims to close. Bad actors have countless ways to pose as trusted entities — through phishing, smishing, vishing, and more. These catchy terms may sound trendy, but the technology to combat them often lags behind. While some larger companies do offer some customised solutions such as in-app notifications, most approaches are still reactive, such as updating email filters after an attack is detected or requesting takedowns of fake domains long after the damage is done. It's surprising that more proactive measures aren't in place, especially considering the serious consequences of these impersonation attacks. How B2V tackles this problem: - Mutual authentication: During critical communications, an organization can initiate an authentication session and share it with a user via a unique URL. When the user opens it, the organization provides a one-time password that the user can verify. These single-use ephemeral sessions also protect against man-in-the-middle attacks, ensuring that the person you're communicating with is truly who they claim to be. This could also be described as *conversational authentication*. - Digital signatures: Prove the authenticity and integrity of information linked to your organization with public-key cryptography. This is especially useful for verifying that text or links posted on platforms/media outside of your control — such as job boards, paper invoices, forums, or messages — truly come from a trusted entity. For example here's the signature of this post's URL: https://b2v.xyz/b2v_/XHEbx8NdqjTF50?s=https://news.ycombinator.com/item?id=40699265 - Verified online identities: Organizations can link their online identities, similarly to the way Keybase does it. For instance, here's the proof of ownership of this HN account: https://b2v.xyz/b2v_/NMiMMr9KWov6oE?s=hn:b2v - Privacy by design: this system respects your privacy by never tracking or storing plaintext identifying information, only digests and signatures. - For deeper integrations, an API is also available. Could this be useful for machine-to-human or machine-to-machine communications, such as chatbots or multi-agent LLMs? Any feedback would be greatly appreciated, especially about my assumptions! Feel free to check out the docs ( https://docs.b2v.xyz ) and ask me anything. Thanks!

Show HN: Buffet – A web-based virtual machine manager
2 by kgdn | 0 comments on Hacker News.
Hi HN! I developed Buffet as a part of my bachelors dissertation and would like to show it to all of you today. Buffet is a full-stack, fully-featured web-based virtual machine manager that aims to provide a free, open-source, easy-to-use, secure alternative to other web-based virtual machine managers such as DistroSea and DistroTest. The back-end is implemented in Python using the Flask framework, while the front-end is implemented in React using TypeScript. Due to the closed source nature of these websites, and the fact that DistroTest shut down a few years ago with little to no warning, I decided to take a stab at implementing the same kind of project for myself. I'm very happy to say that I graduated with a First Class distinction with Honours. Since graduating, I have made the source code fully free and open source, licensed under the GNU AGPLv3. Please let me know what you think, and if you have any other feedback. Thanks!

Show HN: Cofounder matching at small participatory events
3 by bberenberg | 0 comments on Hacker News.
I believe that doing /something/ with someone over and over again is the best way to meet a cofounder. When I get enough people (6-20) in a given city, I will organize an event along the lines of playing board games, going to a driving range, or volunteering in some way. The main point is that it's not just people drinking or standing around, they have to be active participants in the activity. The goal is for you to go to a number of these events, see how others behave and start to build relationships with them. Then you go off and build something with them. Would love to hear your feedback.

Show HN: Raven – automatically organize your book notes
7 by patrikbraborec | 4 comments on Hacker News.
Hi HN! We are Tiago and Patrik. We're building an application to improve the process of taking notes and personal knowledge management. We met through the YC Co-Founder matching platform and we had a common interest of being heavy book readers. We also suffered from the same problem: using notes from books we read. The biggest problems with note-taking are: - Notes in physical books are hard to digitize without introducing significant friction. - People rarely revisit their notes due to poor organization, leading to notes being dumped into files that quickly become gigantic, unusable, and eventually forgotten. - Organizing notes requires a lot time and work. We are solving this by creating a system for the entire note-taking process. We make digitization easy with OCR and UX for selecting the desired text. Post-digitization, we use LLMs to effectively organize the content into an organized database. We categorize content by creating several layers of information that can be used at different times for different purposes: - Title: A short, one-sentence description of the entire note. This is very useful when searching through many notes. - Summary: A single paragraph that distills the information, acting as a thumbnail of the captured information. - Tags: Allows grouping notes based on common topics, regardless of the source. The goal is a system to make content as easy and efficient to navigate and use as possible, automating the process to save time and effort. We differentiate ourselves from other platforms by not overly focusing on AI for its own sake. While many solutions concentrate primarily on summarizing information, we view AI as a tool that supports the overall UX. Our primary focus is on understanding the entire note-taking process holistically—how to capture, search, navigate, and utilize information most effectively. To start with we’re targeting book readers, as this is the most straightforward application. However, we plan to expand this system to accommodate various types of content, including academic papers, articles, podcasts, and more. We’re launching our MVP and gathering feedback from our first users. If you’re interested, you can try it here: https://ravenapp.ai Any feedback is very welcome!

Show HN: Pathway – Build Mission Critical ETL and RAG in Python (NATO, F1 Used)
7 by janchorowski | 0 comments on Hacker News.
Hi HN data folks, I am excited to share Pathway, a Python data processing framework we built for ETL and RAG pipelines. https://ift.tt/pkYfJwy We started Pathway to solve event processing for IoT and geospatial indexing. Think freight train operations in unmapped depots bringing key merchandise from China to Europe. This was not something we could use Flink or Elastic for. Then we added more connectors for streaming ETL (Kafka, Postgres CDC…), data indexing (yay vectors!), and LLM wrappers for RAG. Today Pathway provides a data indexing layer for live data updates, stateless and stateful data transformations over streams, and retrieval of structured and unstructured data. Pathway ships with a Python API and a Rust runtime based on Differential Dataflow to perform incremental computation. All the pipeline is kept in memory and can be easily deployed with Docker and Kubernetes (pipelines-as-code). We built Pathway to support enterprises like F1 teams and NATO to build mission-critical data pipelines. We do this by putting security and performance first. For example, you can build and deploy self-hosted RAG pipelines with local LLM models and Pathway’s in-memory vector index, so no data ever leaves your infrastructure. Pathway connectors and transformations work with live data by default, so you can avoid expensive reprocessing and rely on fresh data. You can install Pathway with pip and Docker, and get started with templates and notebooks: https://ift.tt/5RM1xHI We also host demo RAG pipelines implemented 100% in Pathway, feel free to interact with their API endpoints: https://ift.tt/OdVEJnk We'd love to hear what you think of Pathway!

Show HN: Restate – low-latency durable workflows for JavaScript/Java, in Rust
59 by sewen | 33 comments on Hacker News.
We'd love to share our work with you: Restate, a system for workflows-as-code (durable execution). With SDKs in JS/Java/Kotlin and a lightweight runtime built in Rust/Tokio. https://ift.tt/BiQv92O https://restate.dev/ It is free and open, SDKs are MIT-licensed, runtime permissive BSL (basically just the minimal Amazon defense). We worked on that for a bit over a year. A few points I think are worth mentioning: - Restate's runtime is a single binary, self-contained, no dependencies aside from a durable disk. It contains basically a lightweight integrated version of a durable log, workflow state machine, state storage, etc. That makes it very compact and easy to run both on a laptop and a server. - Restate implements durable execution not only for workflows, but the core building block is durable RPC handlers (or event handler). It adds a few concepts on top of durable execution, like virtual objects (turn RPC handlers into virtual actors), durable communication, and durable promises. Here are more details: https://ift.tt/bfWSIXU - Core design goal for APIs was to keep a familiar style. An app developer should look at Restate examples and say "hey, that looks quite familiar". You can let us know if that worked out. - Basically every operation (handler invocation, step, ...) goes through a consensus layer, for a high degree of resilience and consistency. - The lightweight log-centric architecture gives Restate still good latencies: For example around 50ms roundtrip (invoke to result) for a 3-step durable workflow handler (Restate on EBS with fsync for every step). We'd love to hear what you think of it!

It contains basically a lightweight integrated version of a durable log, workflow state machine, state storage, etc. That makes it very compact and easy to run both on a laptop and a server. - Restate implements durable execution not only for workflows, but the core building block is durable RPC handlers (or event handler). It adds a few concepts on top of durable execution, like virtual objects (turn RPC handlers into virtual actors), durable communication, and durable promises. Here are more details: https://ift.tt/bfWSIXU - Core design goal for APIs was to keep a familiar style. An app developer should look at Restate examples and say "hey, that looks quite familiar". You can let us know if that worked out. - Basically every operation (handler invocation, step, ...) goes through a consensus layer, for a high degree of resilience and consistency. - The lightweight log-centric architecture gives Restate still good latencies: For example around 50ms roundtrip (invoke to result) for a 3-step durable workflow handler (Restate on EBS with fsync for every step). We'd love to hear what you think of it!

Show HN: A React and Next.js UI Toolkit for LLMs
6 by shich | 0 comments on Hacker News.
Hey HN, I wanted to share a UI toolkit project I’ve been working on recently, born out of how difficult I found it to build a great UX on top of LLMs, and keep application state in sync. I’ve built: - A React/JS front-end library for conversational interfaces, which makes it super easy to bootstrap AI assistants and ChatGPT style UX: https://ift.tt/PzwXC9n - A set of adapters that simplify integration with AI backends such as LangServe and HuggingFace The library is highly configurable, easy to theme, supports markdown streaming (that was tough to get right!), custom rendering for AI response components, and it works smoothly with Next.js, React JS (of course), and even plain JavaScript (for the Vue.js folks out there ;). I built it with an architecture I’d love myself as a dev: high code modularity, zero dependencies, wide unit test coverage, and lots of documentation and examples. You can play with codesandbox previews and demos here: https://ift.tt/CvH9AKQ Thanks for reading. It feels like we’re at a new frontier building with LLMs, and I’d love to hear what challenges you’ve had on integrating with them & building great UI & UX.

Show HN: I combined gpt4 and tailwind to create a website builder for developers
2 by BryanMungai | 0 comments on Hacker News.
Hey HN, As a freelance web developer, I've been on the lookout for the perfect static site generator that prioritizes modern design, lightning-fast loading speed, and complete code ownership. I've grown increasingly frustrated with the limitations of popular website builders like Webflow and Framer. Sure, they make the design process easier, but when it comes to having full control over the source code and customizing every little detail, they just don't cut it. I was tired of being locked into walled gardens and dealing with bloated frameworks just to display a simple site. That's why I created InstaWebAI – a static site generator that harnesses the power of AI and Tailwind CSS to create stunning, responsive websites without the unnecessary baggage. With InstaWebAI, you can: Generate blazing-fast static sites from simple text input Enjoy a modern, sleek design right out of the box Customize every aspect of your site using Tailwind CSS Export your code and host it anywhere, ensuring complete control Benefit from a lightweight, self-contained solution without relying on external frameworks As a solo founder, I built InstaWebAI to address my own frustrations and needs as a developer. But I quickly realized that many of my fellow devs were facing the same challenges. InstaWebAI is designed to make your life easier, whether you're building a personal portfolio, a client project, or a complex web application. If you're a developer who values speed, control, and modern design, give InstaWebAI a try. I'd love to hear your thoughts, feedback, and suggestions. Your input is crucial in shaping the future of InstaWebAI and making it the go-to static site generator for developers like us. Thanks for checking out my project! Cheers, Brian Founder of InstaWebAI

Show HN: PlayBooks – Convert on-call documents into executable notebooks
3 by TheBengaluruGuy | 0 comments on Hacker News.
Hello everyone, Dipesh and Siddarth here. We are building PlayBooks ( https://ift.tt/9cVDyuX ), an open source tool to write executable notebooks for on-call investigations / remediations instead of Google Docs or Wikis. There’s a demo video here: https://www.youtube.com/watch?v=_e-wOtIm1gk , and our docs are here: https://ift.tt/mUKvBNJ We were in YC’s W23 batch working on a data lakehouse with support for dynamic log schemas. Eventually we realized it was a product in search of a market and decided to stop building it. When pivoting, we decided to work on something that we originally prototyped (before even YC) but didn’t execute on. In our previous jobs, we were at a food delivery startup in India with a busy on-call routine for backend & devops engineers and a small tech team. Often business impacting issues (e.g. orders dropped by >5% in the last 15 minutes) would escalate to Dipesh as he was the lead dev who had been around for a while and he always had 4-5 hypotheses on what might have failed. To avoid becoming the bottleneck, he used to write scripts that fetched custom metrics & order related application logs every 5 minutes during peak traffic. So if an issue was reported, engineers would check the output of those scripts with all the usual suspects first, before diving into a generic exploration. This was the inspiration to get started on PlayBooks. We’ve put together a platform that can help any dev create scripts with flexibility and without requiring to code much. Our goals were: (1) it can be automated to run and send updates; (2) investigation progress can be shared easily with other team members so everyone has the right context; (3) It can all be done without being on-call or having a laptop access. Using PlayBooks, a user can configure the steps as data queries or actions within their observability stack. Here are the integrations we currently support: - Run bash commands on a remote server; - Fetch logs from AWS Cloudwatch and Azure Log Analytics; - Fetch metrics from any PromQL compatible db, AWS Cloudwatch, Datadog and New Relic; - Query PostgreSQL, ClickHouse or any other JDBC compatible databases; - Write a custom API call; - Query events from EKS / GKE; - Add an iFrame The platform focuses on not just running the tasks but also displaying information in a meaningful form with relevant graphs / logs / text outputs alongside the steps in a notebook format. Some of our users have shared feedback that on-call decision making overload has reduced with PlayBooks as relevant data from multiple tools is presented upfront in one page. Here are some of the key features that we believe will further increase the value to users looking to improve developer experience for their on-call engineers: - Automated surfacing of PlayBooks against alerts & enriching alerts with above-mentioned data; - AI-supported interpretation layer — connect with LLM or ML models to auto-analyze the data in the playbook; - Logs of historical executions to ease the effort of creating post-mortems / timelines and/or share information with peers. If this looks like something that would have been useful for you on-call or will be in your current workspace, we welcome you to try our sandbox: https://ift.tt/Rgj1iNE . We have added a default playbook. Just click on one of the steps in the playbook and then the “Run” button to see the playbook in action. We are excited to hear what you like about the PlayBooks and what you think could improve the oncall developer experience for your team. Please drop your comments here – we will read them eagerly and respond!

As we scaled to more Asian markets and added replicated nodes, the cost started to shoot up while performance got a lot worse. I discovered hosting SQLite on Fly which was crazy fast & cheap with the full power of a relational database but difficult to use and scale without writing tons of code & devops. Then I found Turso as a managed service which is pretty cool but again got really expensive and had to manage a bunch of replications manually and pay per replications (also not a big fan of the UI, lol). Eventually, I found Cloudflare D1, which was amazing both cost at scale and performance with Cloudflare edge infra but it stops there, it's very hard to work with D1 out of the box and to scale it for an actual production platform with tons of limits and without getting locked into the Cloudflare ecosystem. So I built Dzero on top of D1 as a fully managed service that automatically scales globally with over 320 edge locations at no additional cost and can easily be integrated into any platform or framework without getting locked into any ecosystem! The goal of the dashboard was to be like a Supabase for SQLite, meaning that everything should be easily manageable from the dashboard, from creating tables to editing data! Right now we are in early access and would love for you to sign up and give it a try! Feedback is always appreciated! We have big plans for Dzero, check out some of our plans on the site!

4 by jackjoane | 0 comments on Hacker News.
I had the problem of having a boring office job, where im not busy at all, i sit in an office and my bosses keep walking around. And i also enjoy scrolling (twitter) . So to fix this i made a simple free Chrome Extension to make it look like a PDF file. And here i made a little landing page for it. (am proud btw) : https://xdisguise.com/ So i made this :)

Show HN: ChatTTS – A Conversational Text-to-Speech Model for Lifelike Dialogue
2 by Alan_Swift | 0 comments on Hacker News.
As a developer working on conversational AI systems, I've always been fascinated by the potential of text-to-speech technology to bring virtual assistants and chatbots to life. However, during my work on a voice-enabled chatbot project last year, I encountered a frustrating limitation – most existing TTS models lacked the natural expressiveness and nuance required for truly engaging dialogue. The available models often sounded robotic, struggled with proper intonation and prosody, and lacked the ability to convey subtle elements like laughter, pauses, and interjections – all crucial components of natural conversation. I realized there was a pressing need for a text-to-speech model specifically designed for dialogue scenarios, one that could capture the nuances of human speech and deliver a truly lifelike conversational experience. Driven by this realization, I embarked on an ambitious journey to develop ChatTTS, a conversational text-to-speech model tailored for dialogue applications. Over the course of nine months, and after overcoming numerous challenges in data acquisition, model architecture, and fine-tuning, I finally succeeded in creating a powerful TTS system that could synthesize natural and expressive speech, supporting multiple languages and speakers. ChatTTS boasts several key features that set it apart: 1. Conversational TTS: Optimized for dialogue-based tasks, enabling natural and expressive speech synthesis with support for multiple speakers, facilitating interactive conversations. 2. Fine-grained Control: The ability to predict and control fine-grained prosodic features like laughter, pauses, and interjections, adding an extra layer of realism. 3. Improved Prosody: Surpassing most open-source TTS models in terms of prosody, delivering a truly lifelike experience. I'm thrilled to finally share Chat TTS with the Hacker News community. I invite you all to try it out and provide feedback. Let's revolutionize the way we interact with conversational AI!

It's a music player designed for Android platform. However, you can build it for Linux that is my development environment. If you want to build a Macos, ios or Windows version, you can try it without guarantee it will work. It's based on Flutter and Rust.

Show HN: I made an open-source free shipfast but for SvelteKit
1 by jacobxcoder | 0 comments on Hacker News.
I've given myself a 12-month coding challenge to create and validate six mini start-up ideas. Noticing a trend among developers to create and sell their boilerplates, I decided to start the challenge by making a (completely free & open-source) one for myself. I thought it might also be useful for others who like this tech stack. Since I plan to develop and validate ideas quickly during my challenge, having a solid boilerplate is going to be extremely helpful. Here's the stack: - SvelteKit + TypeScript (no NextJS...) - DaisyUI, TailwindCSS - Supabase Auth + Database And this is ready-to-go: - payments with Stripe are already handled - blog-related pages have been created with Contentful - Plausible analytics can be set up in 2 seconds - Supabase authentication pages are also ready Here's a link in case anyone would like to take a look: - page: https://ift.tt/IN03Wan - GitHub: https://ift.tt/v4LZj5Y I'm open to suggestions & feedback. I will now try to code something interesting, starting from this boilerplate. Note: please note that it's fairly recent and I will constantly improve this boilerplate, adding new components, blocks, and improving the overall UI/UX to make it even better in the upcoming future.
