Show HN: Remote terminal via WebRTC, incl. file-transfer – no SSH/VPN required Perhaps the easiest way to get a shell on your remote devices wherever they are (even behind NATs and firewalls) -- no VPN required. Offers file transfer right from the terminal itself. Because it is web-based and connects via WebRTC it is better than VPN + SSH in every way: - no setup required on the client machine, it hence works on all OSs and even your phone, - it will always find the shortest-path to your robots, meaning it won’t go through the cloud if you are on the same network as your robot - still end-to-end encrypted - file upload via drag & drop - file download by clicking on filenames in ls The UI component can be embedded anywhere you like and you can specify the device to connect to directly in the embedding code. This solves a common pain-point in robotics, but seems equally useful in many other applications. Please share your thoughts and questions if you have any!

Show HN: PicnicHR – Simple HR and time-off tracking for your team Hey HN! Picnic started as a side-project during lockdown for internal use, and we recently decided to share with the world as a full product. There's a lot of leave / time-off management applications out there, quite a few we've tried.. We hope Picnic is a more accessible solution, particularly for smaller businesses. An overview of Picnic functionality: - Employees can submit requests for vacation and other time-off, and be notified of their manager's response - Managers and supervisors can process requests for leave, and provide explanation - Team members can view their personal calendar, and managers can view their team's calendar to see upcoming time off, and plan resourcing - Browse all company employees in the employee directory (with the option to make the list visible to all employees, or managers only) - Manage employees information, including personal details, and emergency contacts Picnic is HR software designed to scale to companies of any size, but is especially suited to small and medium businesses. We'd welcome your thoughts on the product, and where we might develop it further! https://picnichr.com August 29, 2023 at 11:15PM

The app connects with your email account, finds all the images you’ve received and shows them in a gallery where you can view and download the ones you want to save. I made this out of curiosity, just to see what pictures were in my account when I first signed up for Gmail 18 years ago. I ended up finding photos of my grandmother and other family members, and old friends and colleagues I’d completely forgotten about. I was surprised by what I found, I hope you will be too.

Show HN: Dataherald AI – Natural Language to SQL Engine https://ift.tt/icNDGM5
Show HN: Dataherald AI – Natural Language to SQL Engine Hi HN community. We are excited to open source Dataherald’s natural-language-to-SQL engine today ( https://ift.tt/sqNUGcE ). This engine allows you to set up an API from your structured database that can answer questions in plain English. GPT-4 class LLMs have gotten remarkably good at writing SQL. However, out-of-the-box LLMs and existing frameworks would not work with our own structured data at a necessary quality level. For example, given the question “what was the average rent in Los Angeles in May 2023?” a reasonable human would either assume the question is about Los Angeles, CA or would confirm the state with the question asker in a follow up. However, an LLM translates this to: select price from rent_prices where city=”Los Angeles” AND month=”05” AND year=”2023” This pulls data for Los Angeles, CA and Los Angeles, TX without getting columns to differentiate between the two. You can read more about the challenges of enterprise-level text-to-SQL in this blog post I wrote on the topic: https://ift.tt/EGrhzC6... Dataherald comes with “batteries-included.” It has best-in-class implementations of core components, including, but not limited to: a state of the art NL-to-SQL agent, an LLM-based SQL-accuracy evaluator. The architecture is modular, allowing these components to be easily replaced. It’s easy to set up and use with major data warehouses. There is a “Context Store” where information (NL2SQL examples, schemas and table descriptions) is used for the LLM prompts to make the engine get better with usage. And we even made it fast! This version allows you to easily connect to PG, Databricks, BigQuery or Snowflake and set up an API for semantic interactions with your structured data. You can then add business and data context that are used for few-shot prompting by the engine. The NL-to-SQL agent in this open source release was developed by our own Mohammadreza Pourreza, whose DIN-SQL algorithm is currently top of the Spider ( https://ift.tt/QU2WtB0 ) and Bird ( https://ift.tt/f8PV4Lq ) NL 2 SQL benchmarks. This agent has outperformed the Langchain SQLAgent anywhere from 12%-250%.5x (depending on the provided context) in our own internal benchmarking while being only ~15s slower on average. Needless to say, this is an early release and the codebase is under swift development. We would love for you to try it out and give us your feedback! And if you are interested in contributing, we’d love to hear from you! https://ift.tt/sqNUGcE August 23, 2023 at 10:38PM

Show HN: VisionScript, abstract programming language for computer vision https://ift.tt/BtqXsFC
Show HN: VisionScript, abstract programming language for computer vision Hello! I'm James and I am working on VisionScript. With VisionScript, I want to empower people -- including everyone without any prior programming experience -- to build cool apps with vision. This weekend, I recorded a demo for VisionScript, in which I made apps that count how many cats are in an image and hides people in a video. Each app was < 10 lines of code. https://vimeo.com/856043804 VisionScript is built for the 10 year old inside of me who would have loved more visual programming languages with which to play. I want to show people the potential of programming and how you can make what you want with computers, whether it be a game that counts cats or an app that monitors how many birds flew past a tree. Those "wow" moments should come as soon as possible in one's learning experience. VisionScript is in active development. I started work on this project in July. There will likely be bugs; this is a passion project. Inspiration comes from Wolfram and Python. Behind the scenes, I am adopting what I am calling "lexical inference", which is to say there is a last state value on which functions infer; the language manages types and state. https://github.com/capjamesg/visionscript August 21, 2023 at 10:48PM

Show HN: Just intonation keyboard – play music without knowing music https://ift.tt/jp6dwEx
Show HN: Just intonation keyboard – play music without knowing music This is a keyboard in just intonation. It can play the notes a piano can. The big difference from a piano is that all the notes become consonant. You can play without knowing any music theory. Hit arbitrary notes with the rhythm you want, and the pitches will work. Not understanding the buttons is fine. Even rolling your elbow around your keyboard is fine. If you are a musician and press the wrong key while playing a song, it will still fit. It will sound like you made an intelligent, conscious choice to play another note, even though you know in your heart it was an accident. Beginner jazz musicians rejoice. It's not an AI making choices for you; it's just a very elegant interface. What makes this possible is several new discoveries in psychoacoustics about how harmony works. While a piano lays out notes in pitch space, this keyboard is able to lay out notes in consonance space. When you play random notes, they tend to be "close together" on the physical keyboard. Distance on the keyboard maps well to distance in consonance space, so those random notes are close together in consonance space and sound good together. According to Miles Davis, a "wrong" note becomes correct in the right context. If you try to play a wrong note, the purple buttons you press will automatically land you in the right context, even if you don't know what that context is yourself. So you can stumble your way through an improv and the keyboard will offer the right notes without needing you to think about it. Harmonic consonance of chords can be read directly off the numbers in the keyboard, which implies that these numbers are a good language to think about music with. It doesn't take years of training, just reading the rules. The subset of playable songs is different from a piano, which means that songs in your existing piano repertoire will snip off some notes. Hardware for thumb keys would fix this, so you could play your existing piano songs in full, plus other songs a piano can't play. I don't have such hardware so I haven't implemented this. The other way is to have two keyboards and a partner. The remaining issue is that there is no sheet music in just intonation. Unfortunately, I have had no success in finding piano sheet music in a common, interpretable format. So while I do have a converter from 12 equal temperament to just intonation, there are no input files to use it with... https://ift.tt/HFvDZyO August 20, 2023 at 02:49AM

Show HN: Run globally distributed full-stack apps on high-performance MicroVMs https://ift.tt/4vs5ABO
Show HN: Run globally distributed full-stack apps on high-performance MicroVMs Hi HN! We’re Yann, Edouard, and Bastien from Koyeb ( https://www.koyeb.com/ ). We’re building a platform to let you deploy full-stack apps on high-performance hardware around the world, with zero configuration. We provide a “global serverless feeling”, without the hassle of re-writing all your apps or managing k8s complexity [1]. We built Scaleway, a cloud service provider where we designed ARM servers and provided them as cloud servers. During our time there, we saw customers struggle with the same issues while trying to deploy full-stack applications and APIs resiliently. As it turns out, deploying applications and managing networking across a multi-data center fleet of machines (virtual or physical) requires an overwhelming amount of orchestration and configuration. At the time, that complexity meant that multi-region deployments were simply out-of-reach for most businesses. When thinking about how we wanted to solve those problems, we tried several solutions. We briefly explored offering a FaaS experience [2], but from our first steps, user feedback made us reconsider whether it was the correct abstraction. In most cases, it seemed that functions simply added complexity and required learning how to engineer using provider-specific primitives. In many ways, developing with functions felt like abandoning all of the benefits of frameworks. Another popular option these days is to go with Kubernetes. From an engineering perspective, Kubernetes is extremely powerful, but it also involves massive amounts of overhead. Building software, managing networking, and deploying across regions involves integrating many different components and maintaining them over time. It can be tough to justify the level of effort and investment it takes to keep it all running rather than work on building out your product. We believe you should be able to write your apps and run them without modification with simple scaling, global distribution transparently managed by the provider, and no infrastructure or orchestration management. Koyeb is a cloud platform where you come with a git repository or a Docker image, we build the code into a container (when needed), run the container inside of Firecracker microVMs, and deploy it to multiple regions on top of bare metal servers. There is an edge network in front to accelerate delivery and a global networking layer for inter-service communication (service mesh/discovery) [3]. We took a few steps to get the Koyeb platform to where it is today: we built our own serverless engine [4]. We use Nomad and Firecracker for orchestration, and Kuma for the networking layer. In the last year, we spawned six regions in Washington, DC, San Francisco, Singapore, Paris, Frankfurt and Tokyo, added support for native workers, gRPC, HTTP/2 [5], WebSockets, and custom health checks. We are working next on autoscaling, databases, and preview environments. We’re super excited to show you Koyeb today and we’d love to hear your thoughts on the platform and what we are building in the comments. To make getting started easy, we provide $5.50 in free credits every month so you can run up to two services for free. P.S. A payment method is required to access the platform to prevent abuse (we had hard months last year dealing with that). If you’d like to try the platform without adding a card, reach out at support@koyeb.com or @gokoyeb on Twitter. [1] https://ift.tt/Ua21YV8... [2] https://ift.tt/pJZrBUC...

Show HN: Zero-dependency minimal Java web framework https://ift.tt/Cn6j5om
Show HN: Zero-dependency minimal Java web framework I have written a from-scratch minimalist Java web framework, called Minum. I'd like to get your thoughts. The driving goal has been achieving characterics of plainness, frugality, performance, maintainability, testability, and ease of use. It has zero dependencies other than Java's SDK, yet provides a web server, routing, authentication, testing, logging, templating, HTML parsing, and a database, in 3800 lines of code, compiling to a 150k binary. It currently supports a web application in production. There are also example projects demonstrating its use, linked in the documentation. As the framework itself has no dependencies, it is built using GNU Make. The example applications that depend on it, however, use Maven as their build tool. Because Minum is still in beta, it is not yet published to Maven - but there are instructions for a workaround. The framework and example apps require Java 20. https://ift.tt/SsxzT9K August 14, 2023 at 01:15AM

Show HN: Automatically convert your GPT-3.5 prompt to Llama 2 Hey HN! I'm working on OpenPipe, an open source prompt workshop. I wanted to share a feature we recently released: prompt translations. Prompt translations allow you to quickly convert a prompt between GPT 3.5, Llama 2, and Claude 1/2 compatible formats. The common case would be if you’re using GPT 3.5 in production and are interested in evaluating a Claude or Llama 2 model for your use case. Here's a screen recording to show how it works in our UI: https://twitter.com/OpenPipeLab/status/1687875354311180288 We’ve found a lot of our users are interested in evaluating Claude or Llama 2, but weren’t sure what changes they need to make to their prompts to get the best performance out of those models. Prompt translations make that easier. A bit more background: OpenPipe is an open-source prompt studio that lets you test your LLM prompts against scenarios from your real workloads. We currently support GPT 3.5/4, Claude 1/2, and Llama 2. The full codebase (including prompt translations) is available at https://ift.tt/GejlbHo.

Show HN: Doculite – Use SQLite as a Document Database Hi! As I was working on a side project, I noticed I wanted to use SQLite like a Document Database on the server. So I built Doculite. DocuLite lets you use SQLite like Firebase Firestore. It's written in Typescript and an adapter on top of sqlite3 and sqlite. Reasons: 1) Using an SQL Database meant having less flexibility and iterating slower. 2) Alternative, proven Document Databases only offered client/server support. 3) No network. Having SQLite server-side next to the application is extremely fast. 4) Replicating Firestore's API makes it easy to use. 5) Listeners and real-time updates enhance UX greatly. 6) SQLite is a proven, stable, and well-liked standard. And, apparently one of the most deployed software modules right now. (src: https://ift.tt/QOJo4br ) What do you think? Feel free to comment with questions, remarks, and thoughts. Happy to hear them.

I often don't have the time to read entire articles. I can save an article as "read later" in my rss app, but I've often lost interest by the time I get to it. Briefed creates two summaries for each article: one detailed, and one tldr. Here is an example of one: https://ift.tt/xja3oJA... 3. Sometimes I've read the full paywalled article and want to read comments here on HN, but hard paywalls limit the engagement those posts will get. Hopefully a detailed summary is enough to start meaningful and curious conversation. I'm still kicking the tires, so the first 500 people to sign up will get the first year free (normal price is $12/year; the price that I felt I would personally pay for such a service). Use the promo code LAUNCH500 at checkout. The code will be automatically invalidated after 500 people use it. Let me know what you think! Any feedback , issues, or questions are welcome. Thanks, Brandon https://briefed.news/ August 5, 2023 at 11:23PM

Show HN: Open-access book on platform governance https://ift.tt/tjfYFEn
Show HN: Open-access book on platform governance Hi there, I'm a political theorist, a professor at Northwestern law school and a founding fellow, board member, etc. of the Integrity Institute. I also was the in-house democratic theorist on Facebook's "civic integrity" (election protection) team for a while, and helped out with the research supporting the creation of the Meta Oversight Board. I just published an academic book with Cambridge University Press bringing together those experiences with research in political science to argue that the way forward for mitigating the harms of big internet platforms and governing user behavior on them is to create global direct democratic institutions for them. You can read the whole book for free on Cambridge's website or by downloading the open-access (license CC-BY-NC-ND 4.0) PDF at the link. If you want a hard copy, you can also buy it in paperback or hardcover. https://ift.tt/VH67XKz August 4, 2023 at 10:51PM

Show HN: Zep – pgvector-based memory store for LLM apps https://ift.tt/Sj65LiF
Show HN: Zep – pgvector-based memory store for LLM apps Hey HN - we launched Zep's document vector DB today. Zep is an open source memory store for LLM apps, and this builds on existing chat history memory persistence, embedding, and enrichment capabilities. Zep uses Postgres and pgvector for database operations and vector search. Vector search can be complicated on Postgres, with careful configuration required at both index creation and query time. We've focused on significantly improving this developer experience. Zep automatically selects index and query parameters for developers based on best practices and known heuristics. Vector database operations are exposed via a simple Python (and LangChain) API for working with document collections, documents, and search results. While we focus on LLM App use cases, you can turn any Postgres instance with pgvector into a vector database with great DX.

Show HN: Using LLama2 to Correct OCR Errors https://ift.tt/H6sZuGf
Show HN: Using LLama2 to Correct OCR Errors I've been disappointed by the very poor quality of results that I generally get when trying to run OCR on older scanned documents, especially ones that are typewritten or otherwise have unusual or irregular typography. I recently had the idea of using Llama2 to use common sense reasoning and subject level expertise to correct transcription errors in a "smart" way-- basically doing what a human proofreader who is familiar with the topic might do. I came up with the linked script that takes a PDF as input, runs Tesseract on it to get an initial text extraction, and then feeds this sentence-by-sentence to Llama2, first to correct mistakes, and then again on the corrected text to format it as markdown where possible. This was surprisingly easier than I initially expected thanks to the very nice tooling now available in libraries such as llama-cpp-python, langchain, and pytesseract. But the big issue I was encountering was that Llama2 wasn't just correcting the text it was given-- it was also hallucinating a LOT of totally new sentences that didn't appear in the original text at all (some of these new sentences used words which never appeared elsewhere in the original text). I figured this would be pretty simple to filter out using fuzzy string matching-- basically check all the sentences in the LLM corrected text and filter out sentences that are very different from any sentences in the original OCRed text. To my surprise, this approach worked very poorly. In fact, lots of other similar tweaks, including using bag-of-words and the spacy NLP library in various ways (spacy worked very poorly in everything I tried). Finally I realized that I had a good solution staring me in the face: Llama2. I realized I could get sentence level vector embeddings straight from Llama2 using langchain. So I did that, getting embeddings for each sentence in the raw OCRed text and the LLM corrected text, and then computed the cosine similarity of each sentence in the LLM corrected text against all sentences in the raw OCRed text. If no sentences match in the raw OCRed text, then that sentence has a good chance of being hallucinated. In order to save the user from having to experiment with various thresholds, I saved the computed embeddings to an SQLite database so they only had to be computed once, and then tried several thresholds, comparing the length of the filtered LLM corrected text to the raw OCRed text; if things worked right, these texts should be roughly the same length. So as soon as the filtered length dips below the raw OCRed text length, it backtracks and uses the previous threshold as the final selected threshold. Anyway, if you have some very old scanned documents laying around, you might try them out and see how well it works for you. Do note that it's extremely slow, but you can leave it overnight and maybe the next day you'll have your finished text, which is better than nothing! I feel like this could be useful for sites like the Internet Archive-- I've found their OCR results to be extremely poor for older documents. I'm very open to any ideas or suggestions you might have. I threw this together in a couple days and know that it can certainly be improved in various ways. One idea that I thought might be fun would be to make this work with a Ray cluster, sending a different page of the document to each of the workers in the cluster to do it all at the same time. https://ift.tt/S4nKCN2 August 2, 2023 at 11:53PM
Show HN: We built swup+fragment-plugin to visually enhance classic websites https://ift.tt/jfIbzU0
Show HN: We built swup+fragment-plugin to visually enhance classic websites ## TL;DR - Progressively enhance your classic website / MPA to a single page app. - Support for fragment visits, comparable to nested routes in React or Vue. - Keep your site crawlable and indexable without any of the overhead of SSR. - No tight coupling of back- and frontend. Use the CMS / Framework / SSG of your choice. - Strong focus on interoperability with DOM-altering JS tools (think Alpine.js, jQuery, ...). - Strong focus on accessibility, even for fragment visits. ## Long Version: Best of three worlds Hi, I'm Rasso Hilber. I have been a web designer and developer since around 2004. From the beginning of my career, I always had to make tradeoffs between 3 goals when building websites: 1. The websites I build should be visually impressive, original, and snappy. 2. The websites I build should be crawlable, accessible and standards compliant. 3. The websites I build should have low technical complexity and be easy to maintain in the long run. In the beginning, I was able to achieve goals 1 (impressive!) and 3 (easy to maintain!) by using Macromedia/Adobe Flash, but due to the nature of the technology horribly failed to deliver crawlable and accessible websites. Later, I found a way to run two sites in parallel for each website I built, one using CMS-generated XHTML for crawlability, one in Flash for the visitors, fetching the data from its XHTML twin. Now I had solved goals 1 and 2, but my setup was awfully complex and brittle. Around 2010, I was relieved to see Flash finally coming to its end. I switched to building websites using PHP, HTML, and jQuery. I could now tick goals 2 (accessibility) and 3 (low complexity), but the websites I was able to build using these technologies weren't as impressive anymore. Hard page loads between every link click being one of the biggest regressions in UX from the days of Flash IMO. Around 2014/15, I first heard about the new frameworks: Angular, React, Vue. These frameworks were not intended to be used for classic websites. They were made for single-page-apps! But it felt to me like no one cared. Even when building classic websites, many developers sacrificed SEO and accessibility for a snappy experience, serving an empty `
` to the browser. I couldn't blame them; I had done the same in my early days as a Flash developer. They ticked goal 1 (impressive) and goal 3 (low complexity). But the lack of accessibility kept me from joining the movement. I was still building classic websites, after all. After some time, many started realizing that serving an empty div had downsides – SSR, hydration, and whatnot were born, now ticking goal 1 (impressive) and goal 2 (accessibility), with the trade-off of awful complexity. It reminded me a lot of my little Frankenstein's monster "Flash+XHTML," and I still didn't want to join the hype. Still, because the noise was so loud, I felt like I might be becoming obsolete, an "old man yelling at the clouds". New very interesting tools like HTMX or Unpoly popped up that looked promising at first, but at closer inspection weren't optimized for my use case either. These were primarily built for real interfaces/single-page-apps (html snippets instead of full pages, UI state independent of URLs, altered DOM saved in history snapshots, ...). I wanted to find a tiny tool, optimized for building presentational , content-driven websites with a strong focus on accessibility . Instead, after a few years of rolling my own home-grown solutions, I started using swup[0], a "Versatile and extensible page transition library for server-rendered websites". Swup consists of a tiny core and a rich ecosystem of official plugins[1] for additional functionality. It was hitting the sweet spot between simplicity and complexity, and felt like it was perfect for my use cases. Shortly after I had started using it, I became a core contributor and maintainer of swup. The only thing I was still missing to be a happy developer was the ability to create really complex navigation paths where selected fragments are updated as you navigate a site, much like nested routes allow in React or Vue. The last two months I teamed up with @daun [2] to finally solve this hard problem. The result is two things: 1. A new major release of swup (v4) that allows customizing the complete page transition process by providing a powerful hook system and a mutable visit object 2. The newly released fragment-plugin [3] that provides a declarative API for dynamically replacing containers based on rules Use cases for the fragment-plugin are: - a filter UI that live-updates its list of results on every interaction - a detail overlay that shows on top of the currently open content - a tab group that updates only itself when selecting one of the tabs - a form that updates only itself upon submission I can now finally build websites that tick all three boxes: 1. Visually impressive, fun, and snappy by using swup's first-class support for animations[4], cache[5], and preload capacities[6], enhanced with fragment visits as seen on the demo site. 2. Accessible by being able to serve server-rendered semantic markup that will fully work even with JavaScript disabled (try it out on the demo site!). On top of that, swup's a11y plugin[7] will automatically announce page visits to assistive technologies and will focus the new `
` element after each visit. 3. Because now all I need for my fancy frontend is a bit of progressive JavaScript, I can choose whatever tool I like on the server, keeping complexity low and maintainability high. I can use SSGs like eleventy or Astro (the demo site is built using Astro!), I can use any CMS like WordPress or ProcessWire, or a framework like Laravel. And I don't have to maintain an additional node server for SSG! The plugin is still in it's early stages, but I have a good feeling that this finally is the right path for me as a web developer. All it took was 20 years! ;) [0] https://ift.tt/TZ0BmG5 [1] https://ift.tt/7XGdD80 [2] https://github.com/daun [3] https://ift.tt/FfR1SEG [4] https://ift.tt/Z6i59he [5] https://ift.tt/AklIXG1 [6] https://ift.tt/6iYsDH7 [7] https://ift.tt/z5KqFHt https://ift.tt/zeovdOC August 2, 2023 at 04:15PM
