Show HN: MiniSearch, a minimalist search engine with integrated browser-based AI https://ift.tt/iafGKnV

Show HN: MiniSearch, a minimalist search engine with integrated browser-based AI Hey everyone! I’m excited to announce the release of my last project, MiniSearch. I admire Perplexity.ai, Phind.com, You.com, Bing, Bard and all these search engines integrated with AI chatbots. And as a curious developer, I took the chance and created my own version. Using Web-LLM and Transformers.js to provide browser-based text-generation models on desktop and mobile, I built a minimalist self-hosted search app on which an AI analyses the results, comments on them and responds to your query summarising the info. In the backend, it still queries a real search engine, but besides that, there's no other remote connection happening. For running in the browser and on mobiles, lightweight models are required, so we can't expect them to give stellar answers, but there are a few advantages of using this over the services as mentioned earlier: - Availability: The AI will always be available and respond with the maximum available speed from the device. - Privacy: Besides the queries that go anonymously to the actual search engine, nothing else leaves your device. - No ads/trackers: Get the relevant links clean and fast without being tracked. - Customization: As it's open-source, you can fork it and re-style it any way you want. You can get started with MiniSearch by cloning the repository from GitHub ( https://ift.tt/GlSdcsq ) and running it locally or by using it online on this HugginFace Space: https://ift.tt/1dyDTpf (Alternative Space address: https://ift.tt/45Cwn2L ) You can even set it as your browser's address-bar search engine using the query pattern ` https://ift.tt/H7x3iBq ` (where your query replaces %s). At the moment of this writing, the app is using TinyLlama and LaMini-Flan-T5 models, but there's an option to try to use larger models like Mistral 7B (not recommended, though, as it could be slow and break the fast-search experience). That's what I had to share. Thanks for reading! Your feedback means the world to me! Please don't hesitate to reach out if you have any questions or suggestions or want to learn more. https://ift.tt/45Cwn2L October 15, 2023 at 06:20AM

Show HN: A lightweight open-source web analytics for webdevs https://ift.tt/16UTVOB

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

Show HN: Standalone Jdk.compiler, Java Compiler Framework and Tree API https://ift.tt/T1xvimP

Show HN: Standalone Jdk.compiler, Java Compiler Framework and Tree API With this standalone compiler, you can rely on all Java 11 javac features to be available, even when using newer Java versions. Specifically, this allows you to: - compile code even if your Java environment isn't a full JDK (Java JRE, for example!) - target Java 1.7 for compilation without any warnings or restrictions. - use the Compiler Tree API without resorting to --add-opens trickery that may eventually fail in newer Java releases - build a modified compiler with additional features or custom tweaks I made this after finding that the otherwise superb "jsweet" Java-to-JavaScript transpiler failed to build and run with Java 16 or newer. Surprisingly, I couldn't find any prior work other than "proper" standalone compilers like Eclipse's ecj that would properly work with modern Java runtimes. I'm excited to see what can be done now that we have this scaffolding. https://ift.tt/lPi6ygt October 10, 2023 at 10:15PM

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

Show HN: A job application tracker with company reviews, recruiter autoresponder https://ift.tt/F57kQg2

Show HN: A job application tracker with company reviews, recruiter autoresponder Hey folks. Rolepad is a product born out of my dissatisfaction with hiring processes - both as a candidate and as a hiring manager. Processes that are non-transparent, inefficient, and full of frustration for both sides. This early iteration has focused on the application tracking aspects with a few extra goodies. These days it is common to apply to dozens of positions (some users track over a hundred opportunities). Without a record-keeping system, it can quickly become an unmanageable mess. Even the better-organized among us often end up juggling spreadsheets, emails, and various notes. Rolepad was built to keep this data (company facts, role details, interview stages, contact info, freeform notes, follow-up actions, and more) in one place. Some of the other neat additions: - Forward emails to save@rolepad.com to save them as notes connected to specific opportunities. Forward recruiter messages to no@rolepad.com to have the system automatically reply with a decline response. - Generate shareable Sankey charts of your progress like this: https://ift.tt/kbmIa0M - Submit anonymous reviews and insights about application/interview/offer processes at a company . This is new and there aren’t great examples to share yet ( https://ift.tt/JwufCr1 is an early glimpse), and I didn’t want to create fake data as a matter of principle. Oh yeah, and it’s totally free :) Creating an account is passwordless and takes seconds, but if you want to kick the tires even faster, I created test credentials for this occasion: username: test@rolepad.com password: hntest With this release, I am also starting conversations with employers ( https://ift.tt/5LfvbzG ). A unified platform for candidates and employers can significantly reduce frustration for both in ways that email cannot. I should note that any solutions here have privacy implications and will require an exceedingly thoughtful execution. And now for the tech stack. The main application uses React with Tailwind on the frontend, C# on the backend, hosted in AWS (App Runner, Lambda, RDS Postgres, SES), with auth provided by Google Firebase, and CI/CD via GitHub Actions. The home page is actually an SSR (server-side rendered) application built with vite-plugin-ssr (now vike) and hosted in a Cloudflare Worker that hits the AWS-hosted API. This is basically a best-of-all-worlds SSR configuration - very fast, zero cold start (!), and essentially free. Any and all feedback is sincerely appreciated! https://rolepad.com October 6, 2023 at 09:31PM

Show HN: Dittofeed v0.5.0 – Self-host SMS and email customer messaging Hey HN, we’ve just released Dittofeed v0.5.0, with the primary change being the addition of SMS as a messaging channel. Dittofeed is an open source (MIT licensed) omnichannel customer engagement platform, similar to Customer.io and Iterable. We added: - Twilio-based SMS messaging. You can create SMS templates and customer journeys within Dittofeed. SMS is a great channel for B2C software companies, looking to engage with their users. For example, e-commerce businesses commonly use SMS to support checkout flows. We'll be making further enhancements to Dittofeed's SMS support in the coming weeks! - We added a new "Trait Exists" segmentation option, which can be used to create a segment of all users with phone numbers, for example. - We made some fairly large improvements to our settings UI. Big shout out to our contributor! https://ift.tt/3wO5hfi The full feature release blog post can be found here: https://ift.tt/zQ6DSXH . Looking forward to your thoughts and feedback!

Show HN: Running LLMs in one line of Python without Docker https://ift.tt/fG2gYkA

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

Show HN: Hardcover – Letterboxd for Books https://ift.tt/EFSd9nG

Show HN: Hardcover – Letterboxd for Books Hi HN! A little over two years ago, Goodreads announced they were shutting off access to their API. I was using it to show what I was reading on my blog at the time, and started looking for alternatives. I found a few that showed potential. I'd been using Letterboxd for a few years at that point and felt it had something that was missing from GR and the others I found, but I couldn't put my finger on it. I decided to build it instead (I'm sure many creators can relate ). I made a post on the /r/cofounders subreddit about the idea, and found Ste. With me as a full-stack product dev and him on product design, we talked to hundreds of readers about what they want in a book tracking and social platform. We've listened to their feedback, tested and iterated constantly. We believe we've created a book space that feels as warm as a familiar library but as exciting as a midnight book launch party. This past weekend we launched Hardcover on Product Hunt (and hit #3!). We describe Hardcover as a book tracking social network for readers to find new books, track what they read and make lasting connections with other readers. So, Letterboxd for books! Here are a few of my favorite things you can do on Hardcover: Find books - Search for books you know of, check out trending books, explore lists and prompts to find hidden gems, review your recommendations, stumble on friends reads in your feed, or browse all book by genre, mood or tag. Decide what to read - Besides all the book facts you'd expect to see, we show you a personalized Match Score from 0% to 100% for each book based on your reading history. You'll also see ratings & reviews from readers you follow and readers most similar to you. Track your reading - One place for every book you want to read, have read and more. You can set your privacy level to public, private (for a book?) or friends only. Use Airlists (our version of Airtable for Books) to further organize your library. Log your reads - Rate and review books on a 5-star scale with half-star increments. Showcase your favorite books on your profile at hardcover.app/@username Read even more - Set reading goals and explore your reading stats through charts and data visualizations to help keep you consistent and understand your own reading habits and tastes. AI librarian, Bookle game, referral program, Goodreads/StoryGraph importer, GraphQL API, light/dark modes, an active Discord and so much more! I'm excited to share and get feedback from the Hacker News community we've all been a part of for so long (even if I've mostly lurked here since 2009 ). In terms of launch numbers (which I always love to see), here's our dashboard that shows how it went. We had about 250 new members join in the last 3 days, and a few new subscribers. We're still a ways away from being profitable. It costs us about $1,000/month to run Hardcover – even before salaries. We're about 30% of the way there. https://ift.tt/yOB4h1a... I'm most excited about the momentum from launch - seeing people share Hardcover with friends of theirs who read and growing the community. If you're a reader I'd love to invite you to join us! Any feedback, questions or comments are always welcome. I'm an open book, so feel free to ask me anything. Adam https://ift.tt/Gc4k8uT https://hardcover.app October 3, 2023 at 03:16AM

Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community https://ift.tt/NRfInLm

Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community Hey friends! We have built an app for getting insights about your favorite GitHub community using large language models. The app uses LLMs to analyze the GitHub profiles of users who have starred the repository, capturing key details like the topics they are interested in. It takes screenshots of the stargazer's GitHub webpage, extracts text using an OCR model, and extracts insights embedded in the extracted text using LLMs. This app is inspired by the “original” Stargazers app written by Spencer Kimball (CEO of CockroachDB). While the original app exclusively used the GitHub API, this LLM-powered app built using EvaDB additionally extracts insights from unstructured data obtained from the stargazers’ webpages. Our analysis of the fast-growing GPT4All community showed that the majority of the stargazers are proficient in Python and JavaScript, and 43% of them are interested in Web Development. Web developers love open-source LLMs! We found that directly using GPT-4 to generate the “golden” table is super expensive — costing $60 to process the information of 1000 stargazers. To maintain accuracy while also reducing cost, we set up an LLM model cascade in a SQL query, running GPT-3.5 before GPT-4, that lowers the cost to $5.5 for analyzing 1000 GitHub stargazers. We’ve been working on this app for a month now and are excited to open source it today :) Some useful links: * Blog Post - https://ift.tt/9efhlxp... * GitHub Repository - https://ift.tt/61Obgif * EvaDB - https://ift.tt/agJGDn8 Please let us know what you think!

Show HN: Dolce – Get notified if something (bad) happens to your containers https://ift.tt/qES5yZV

Show HN: Dolce – Get notified if something (bad) happens to your containers Hi HN, while I was on vacation this year the shop of my wife was suddenly down and we only noticed once the emails of customers rolled in. After fixing it on my phone I thought there has to be a better way to notice when your docker container die or are in a restart loop for whatever reason. Now I know there are lots of tools like healthcheck.io and monocker, however none seemed to match my simple use case of getting notified _via email_ when the running– or health-status of any docker container changes. So I did what every SE would do in that case and hacked another solution but this one is mine :). I also always wanted to do a project with deno and get up to speed on typescript. This was also a great reason to finally look into using GitHub Actions to automate some of the tedious tasks. Fun fact: After reading on here about Deno Queues, I rewrote the message buffering and backoff completely and could greatly simplify the code. TL;DR - What is this: Get notification via - EMail (BYOSMTP) - Discord - Telegram if any (or only selected) containers on your host die or change their health status. I also tried to handle unexpected restarts of the container the tool is running in gracefully without loosing any events that happened before and even while the service was down. To make sure you are not spammed by notifications if a container goes into a restart loop, there is also a configurable exponential backoff function. I tried to make using the tool as easy as possible (by getting inspired on how monocker is set up). I would love to get some feedback and hear what you think (also if I just missed the perfect tool for the job: let me know, however the journey was quite fun). https://ift.tt/tpN43nW September 29, 2023 at 11:11PM

Show HN: Ultra-Realistic Generative Fill with AI and 3D https://ift.tt/UjIyoYF

Show HN: Ultra-Realistic Generative Fill with AI and 3D Hey all, You've probably seen projects that add objects to an image from a style or text prompt, like InteriorAI (levelsio) and Adobe Firefly. The prevalent issue with these diffusion-based inpainting approaches is that they don't yet have great conditioning on lighting, perspective, and structure. You'll often get incorrect or generic shadows; warped-looking objects; and distorted backgrounds. ### What is Fill 3D? Fill 3D is an exploration on doing generative fill in 3D to render ultra-realistic results that harmonize with the background image, using industry-standard path tracing, akin to compositing in Hollywood movies. ### How does it work? 1. Deproject: First, deproject an image to a 3D shell using both geometric and photometric cues from the input image. 2. Place: Draw rectangles and describe what you want in them, akin to Photoshop's Generative Fill feature. 3. Render: Use good ol' path tracing to render ultra-realistic results. ### Why Fill 3D? + The results are insanely realistic (see video in the github repo, or on the website). + Fast enough: Currently, generations take 40-80 seconds. Diffusion takes ~10seconds, so we're slower, but for the level of realism, it's pretty good. + Potential applications: I'm thinking of virtual staging in real estate media, what do you think? ### Check it out at https://fill3d.ai + There's API access! :D + Right now, you need an image of an empty room. Will loosen this restriction over time. Fill 3D is built on Function ( https://fxn.ai ). With Function, I can run the Python functions that do the steps above on powerful GPUs with only code (no Dockerfile, YAML, k8s, etc), and invoke them from just about anywhere. I'm the founder of fxn. ### Tell me what you think!! PS: This is my first Show HN, so please be nice :) https://ift.tt/A1mzDdj September 29, 2023 at 02:11AM

Show HN: Use ChatGPT with Apple Shortcuts https://ift.tt/5gm0GC3

Show HN: Use ChatGPT with Apple Shortcuts This project was born from my passion for every Apple product and the entire ecosystem, along with the power of ChatGPT. I was tired of copy-pasting and switching between apps on my Mac or iPhone, so I had this crazy idea to bring ChatGPT into every app that I use. This was possible only with the Apple Shortcuts app. Very few people know about its power and potential, so I took this chance and built COPILOT. https://meetcopilot.app But I also loved the idea of AI agents using various tools so much that I leveraged OpenAI's function-calling feature to accomplish that. Now, no matter what app I am using on my iPhone or Mac, the selected text or the current webpage from Safari will be passed automatically to COPILOT. Then I just ask it whatever I need and watch until it reaches the goal autonomously. There was also another problem with ChatGPT - the knowledge cutoff. So I also integrated Google search and web scraping into it. Now, whenever my request needs real-time information, like what is the latest version of macOS, it will use these tools to gather the data and then give me the correct response. Being an app built with Apple Shortcuts, all its "code", called actions, is actually open-source. I'm selling a Premium version of it to earn some revenue for my time. I would love to hear all your thoughts on it! Thank you so much! https://ift.tt/wIpT680 September 27, 2023 at 02:07PM

Show HN: A simple API/CLI for scheduling HTTP requests https://ift.tt/RHYUq0g

Show HN: A simple API/CLI for scheduling HTTP requests Hi HN! This is something I've been tinkering on for the past couple months. It's basically just an API/CLI for scheduling delayed or recurring jobs as HTTP requests. I initially built it as a personal tool to save myself a bit of time on little side projects where I've needed scheduled/recurring alerts, but decided it could be a good opportunity to practice building out a nice landing page [0] and documentation [1]. And who knows, maybe someone else will find it useful ¯\_(ツ)_/¯ The tool relies heavily on Elixir's Oban [2] library for managing jobs, and Mintlify [3] for documentation. I also shamelessly stole most of the frontend design from Resend [4] because I'm a fan of the aesthetic and thought it would be good for my design chops to use their design as a guide. I also discovered Radix [5] UI while working on this, which ended up being immensely helpful for moving quickly on the frontend. Anyways, I almost certainly spent a bit too much time on small UX details that are most likely utterly inconsequential, but it was a fun exercise in polish :) All feedback is welcome!

Show HN: Using LLMs and Embeddings to classify application errors https://ift.tt/913ayrL

Show HN: Using LLMs and Embeddings to classify application errors Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different stacktrace and body, but are semantically not very different). Each of these rely heavily on comparing text across our application. After some experimentation with the OpenAI embeddings API [3], we went ahead and hosted a private model instance of thenlper/gte-large (an open-source MIT licensed model), which is a 1024-dimension model running on an Intel Ice Lake 2 vCPU machine on Hugging face [4]. Our general approach for classifying/comparing text is as follows. As each set of tokens (i.e a string) comes in, our backend makes a request to an inference endpoint and receives a 1024-dimension float vector as a response (see the code here [5]). We then store that vector using pgvector [6]. To compare any two sets for similarity, we simply look at the Euclidian distance between their respective embeddings using the ivfflat index implemented by pgvector (example code here [7]). To tag errors, we assign an error its most relevant tag from a predetermined set decided by us. For example, if we tag an error as an "authentication error" or a "database error", we can allow developers to have a starting point before inspecting an issue.(see the logic here [8]). Anecdotally, this approach seems to work very well. For example, here are two authentication errors that got tagged as “Authentication Error”: * Firebase: A network AuthError has occurred * Error retrieving user from firebase api for email verification: cannot find user from uid. We also use these error embeddings to group similar errors. To decide whether an error joins a group or starts a new one, we decide on a distance threshold (using the euclidean distance) ahead of time. An interesting thing about this approach, compared to using a text-based heuristic, is that two errors with different stack traces can still be grouped together. Here’s an example: * github.com/highlight-run/highlight/backend/worker.(*Worker).ReportStripeUsage * github.com/highlight-run/highlight/backend/private-graph/graph.(*Resolver).GetSlackChannelsFromSlack.func1 Both reported as `integration api error` as they involve the Stripe and Slack integrations respectively. The neat thing is that the LLM can use the full context of an error and match based on the most relevant details about the error. We have rolled out a first version of the error grouping logic to our cloud product [9], and there’s a demo of all the functionality at [2]. Long-term, if the HN community has other ideas of what we could build with LLM tooling in observability, we’re all ears. Let us know what you think!
