Show HN: Which is faster? Puppeteer, Playwright or Selenium https://bit.ly/3RaUE6n

Show HN: Which is faster? Puppeteer, Playwright or Selenium Hey Everyone, I just ran a [rather silly] race between Puppeteer (JS), Playwright (Python) and Selenium (Python) to see which one would be fastest on a simple scrape (using Google Colab so you can also run it) Far from a comprehensive benchmark, this race is 100% free from advanced configurations, multi-threading or anything complicated. It just opens Wallapop (a second hand marketplace in Spain) and times how long it takes to extract the first 2000 results of a search. If you like this simple format, have any ideas on how to improve a race like this or have a strong urge to prove Ward Cunningham wright, let me know in the comments! https://bit.ly/3sNMy9C September 9, 2023 at 12:24PM

Show HN: Trickle – Let GPT-4 Understand Your Screenshots https://bit.ly/3LfXjYD

Show HN: Trickle – Let GPT-4 Understand Your Screenshots Hey there HN! It took nearly 5 years for my team and me to truly find right direction. So, after introducing our work, I'm keen to share the story behind it. The following content is divided into two parts. If you're not interested in the backstory of the product, feel free to skip the content after the divider. > The Problem We're Solving: During a casual afternoon, while brainstorming what to do next on a WeWork sofa, we realized that almost everyone present had a habit of saving information via screenshots. When I opened my photo gallery, I was astonished to see that more than half were such screenshots. Given that traditional OCR and gallery apps hadn't really addressed our screenshot chaos, we decided to build something to solve our own problem. > How it works: At first glance, you might think Trickle is a manual screenshot version of Rewind. But in reality, they're vastly different. All you need to do is send your screenshots, and let Trickle handle the rest: [1] Trickle doesn't constantly record the entire desktop, so it won't consume all your Mac's storage or affect its performance. Moreover, it won't give you the unsettling feeling of being constantly watched. [2] Although we have a Mac screenshot tool, and a browser extension is on its way, you don't actually need to install them. You can easily upload your screenshots via a web page. This makes it platform-agnostic; you can browse, search, and ask about your historical screenshots at any time via a browser. Of course, it doesn't occupy any of your local storage. Last but not least, it's Windows-user friendly. [3] User-controlled screenshots mean that the embedded chunks are semantically more precise. Beyond the advanced reasoning capabilities of GPT-4, we've integrated some tricks of our own, allowing Trickle to truly comprehend your screenshots, rather than just summarizing the text. Sometimes you might be surprised when Trickle even reasons out essential information that's not present in the image. This also ensures a better experience when you try to recall information. ------------The Story Behind the Product:------------ In 2018, I left my consulting role and dove head-first into the startup world with two co-founders. Our initial venture involved creating a visual recognition model for a vending machine company, marking our first income. Yet, custom builds weren’t sustainable, prompting our first pivot. By 2019, we were deep into retail tech, winning a demo day and launching a product to automate in-store promotions. The climax seemed to be our partnership with a large multinational, but 2020 and the pandemic shifted landscapes. We then explored the realm of asynchronous video, building an alternative to Loom. By 2021, we hit 10k users, but profitability remained elusive. As workspaces evolved and people returned to offices, we sensed another opportunity. Our solution? An in-house social platform for teams, named "Trickle". In 2022, after a launch on Product Hunt, even though we garnered attention from people like Ryan Hoover and former Microsoft VP Lu Qi, we faced a stark realization: Daily team updates might not be as 'cool' as anticipated. Our anxiety steered us off-path, and soon, Trickle became a bulky hybrid, attempting to replace tools like Notion and Slack. Looking back, this detour was a misstep. The turning point came mid-2023. A series of tepid Product Hunt launches forced introspection. We stripped Trickle down, retaining only its name and began anew. Today, with the original team intact, we're addressing an everyday issue that resonated with all of us: the chaos of managing screenshots. Reflecting on our journey, it's clear that the essence of the startup spirit lies in adapting, evolving, and pursuing that 'Eureka' moment, no matter how winding the path. https://bit.ly/3LcmMCc September 8, 2023 at 01:44PM

Show HN: ChatGPT Powered Code Analysis https://bit.ly/3r7Wmec

Show HN: ChatGPT Powered Code Analysis I'm building an AI platform, FlowChai and found a neat use case for it today that I thought would be useful to HN readers. I use GPT4 heavily for writing / editing code, but a major downside is that it doesn't know about new projects. I made the connection today that I could upload the zip file of a Github repo to FlowChai and then write prompts just like with ChatGPT with code questions. While the original intent for this platform is more around natural language, it's neat how this works so well. It's powered underneath by pgvector and OpenAI embeddings. https://bit.ly/3LhCLil September 8, 2023 at 01:19PM

Show HN: Rivet – open-source AI Agent dev env with real-world applications https://bit.ly/3RaoGXJ

Show HN: Rivet – open-source AI Agent dev env with real-world applications We just launched Rivet, the open-source visual AI programming environment! We built Rivet, because we were building complex AI Agent applications at Ironclad. It unlocked our abilities here, and we're excited to make available to the entire community. Backstory: A few months ago, inspired by things like LangChain and LlamaIndex, we started building an AI agent that could work with legal contracts. Unfortunately, we couldn't just use retrieval augmented generation (RAG), because a lot of contracts are basically identical (many chunks with near-identical embeddings), except for a few key details. So, we turned to things like ReAct and AutoGPT for inspiration. At first, things went great. We were adding agent capabilities, doing chain-of-thought prompting. But then we hit a wall. The agent became too complex. We had debugger breakpoints on almost every line of code, but we still had no idea where the agent was breaking. Every change we made destabilized something else. After two weeks of fumbling, I decided to end the project. But one of my teammates, Andy, didn't give up. The following week, he showed me v0 of Rivet. He'd used it to refactor and improve our existing agent. I was skeptical... it just seemed like a visual programming environment, and I was not a fan. But I gave it a shot, and suddenly found myself able to add new skills to the agent, debug brittle areas with ease, and update prompts with confidence. Rivet is a game-changer. And more than that, it makes building with LLMs super fun. What exactly makes it different? First, the debugger is incredible. You have to experience it to believe it. You can update a graph, and then immediately run it, and see where it succeeded or failed. Even better: you can attach Rivet as a remote debugger, and watch your agent graphs execute in your app. Second, visual programming is actually a game-changer for prompting LLMs. I don't know why exactly, but it's way easier to understand and organize your work when you have an extra dimension to work with. Finally, Rivet is built to be embedded into a larger application (TypeScript for now, but we've also found a way to run it in Python). Beyond importing Rivet as a dependency, you can also define "external functions" dynamically at run-time. It feels pretty sketchy to give a LLM a key and unfettered access to an API. With Rivet, you can give it access to a specific set of defined functions, potentially pre-scoped to the access level you want. ...Sorry that was long. If you read this whole thing, thank you! We're really excited to hear what you think! We just launched our first Rivet-based application at Ironclad, and we've been working with companies like Sourcegraph, Attentive, AssemblyAI, Bento, and Willow to make Rivet useful for others. https://bit.ly/462leml September 8, 2023 at 02:29PM

Show HN: HackYourNews – AI summaries of the top HN stories https://bit.ly/3PvyYkc

Show HN: HackYourNews – AI summaries of the top HN stories Hey there HN! I wanted to share a pet project of mine. I built HackYourNews [1] to scratch a personal itch: Knowing which stories to focus on while browsing aimlessly (though there is a certain joy in that, as well!) HackYourNews uses OpenAI's gpt-3.5-turbo to summarize the destination article as well as the comments section. Summarization of the article is always cached, while summaries of the comments are regenerated if the comments count is >10% (or >10 comments) different. While I styled the homepage to welcome HNers, my preferred view is the Mobile view, accessed from the navbar. This no-frills view honors OS-level dark mode and is easy to skim on any device. Tried to keep the site minimal. The only JS is Cloudflare's privacy-preserving analytics [2], just to gauge interest. This is the first time I'm releasing something to the wild. Hope you find this useful! The frontend is pure HTML+CSS. The backend is Python with the excellent Microsoft Guidance [3] library to interface to OpenAI's API.

Show HN: Curated custom search engine portal https://bit.ly/44L1S45

Show HN: Curated custom search engine portal Hey friends, a little background - A friend of mine who’s also a newsletter writer once told me that when he’s interested in certain topic he would like to know the opinion of some of his favorite writers on the same topic. He would use Google to search something like discomfort site:sive.rs, and then expand his search across various authors he admires. It turns out that Google’s programmable search engine does exactly that. By simply adding a few websites (much like subscribing to newsletters or RSS feeds), we can craft a search engine tailored for our specific needs. I think that's a great idea - more signal and less noise. So I built a portal to facilitate sharing personal curations https://bit.ly/3L9umgL .

Show HN: uDSV.js – A faster CSV parser Hey folks! I know CSV parsers (especially in JS) aren't terribly exciting and someone writes a "better" one every week. I'm in the middle of my parental leave, and this was a project that came out of me looking for the fastest/smallest CSV parser. It all started so innocently, and then turned into a benchmark-validation-athon; the library itself took ~2 weeks to write, but the performance comparisons took another ~4 weeks (on and off). The benchmarks were a huge effort, but I think they are the most thorough to date, both in breadth and in depth, so hopefully you find them useful: https://bit.ly/3rcacfk Let me know if you have specific concerns / questions / improvements :) cheers!
