Show HN: ParallelGPT – Batch processing with ChatGPT on low-code spreadsheet UI https://ift.tt/LeMp2hA

Show HN: ParallelGPT – Batch processing with ChatGPT on low-code spreadsheet UI We made ParallelGPT - a tool that lets you bulk process chatGPT on a spreadsheet UI instead of one-by-one conversation style. Hopefully this saves you time and hassle - especially if you want to build an operational process around it and want to collaborate your team. You can give it a quick spin on this live demo playground: https://ift.tt/zZNEJLD... I am the co-founder of Rowy( https://www.rowy.io ), an open-source low-code platform, and we built ParallelGPT as a fun showcase of what you can do with low-code. There are tons of exciting AI apps you can build with low-code, and we're always happy to chat about any ideas you have and assist on our Discord. https://ift.tt/PfSKVmX April 1, 2023 at 08:47AM

Show HN: DigicamFinder – open-sourced DPReview camera data Ever since the DPReview closure announcement https://ift.tt/GnpA0Sh we were thinking how to preserve the 25 years of valuable DPReview camera data. Archive.org has been great, but it's not usable by the general public. The best way to keep it safe going forward, is to have the community own it, so we open sourced it: https://ift.tt/hMLYrFP I'm aware of a number of attempts to make product data open-sourced, but none have the power of the photo geeks behind it :) Thoughts or ideas? + really looking for some contribution love. https://ift.tt/DJPztcZ April 1, 2023 at 06:42AM

Show HN: Simply explain 20k concepts using GPT https://ift.tt/26KYC8E

Show HN: Simply explain 20k concepts using GPT Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even about, so this was a way to get the high level idea about random things that I wanted to know about. It also only uses the information in the GPT model at the moment, so obviously information can't be trusted completely and you should definitely double check any information you read here by Googling. I'm thinking of doing the Bing Chat approach for the next version and adding references, but don't have that yet Hopefully someone else finds this useful even if it's not perfect! https://ift.tt/uJQr07b April 1, 2023 at 06:24AM

Show HN: Cadseer. a parametric solid modeling CAD desktop application https://ift.tt/uDIvjF5

Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/mg8uK4l April 1, 2023 at 02:35AM

Show HN: Kaskada – modern, open-source event processing https://ift.tt/8dstajQ

Show HN: Kaskada – modern, open-source event processing We recently open-sourced Kaskada – an event-processing engine built on Rust and Apache Arrow. It features a high-level, declarative query language designed specifically for reasoning about events in bulk and in real time. Unlike SQL, an aggregation over events produces a timeline indicating the value at each point in time over the events that have occurred up to that point in time. The query language provides composable, expression oriented syntax, including the ability to nest aggregations. Due to the focus on events and temporal queries, it provides capabilities to shift events forward (not backward, to avoid "leaking" information about the future into past values), ticks that create new times (allowing you to observe the current value of an aggregation every day, for instance) and joins that operate "at the current time". Example query: # Purchases up to a point in time let purchases_now = count(purchase) # Shift that *forward* one day (so the value now is from 1 day ago) let purchases_yesterday = purchases_now | shift_by(days(1)) # Compute the difference (purchases since yesterday) in purchases_now - purchases_yesterday More on the history of Kaskada is available in this blog post https://ift.tt/AnhfK9D . More information on the project (and documentation) is available at https://kaskada.io . https://ift.tt/6LpOQ2I March 31, 2023 at 02:27AM

Show HN: Telltail – Universal Clipboard for Text Hi folks! Telltail [1] lets you copy text from one device onto another. If you've used or ever known about Apple's Universal Clipboard, it is quite like that. It uses Tailscale [2] to achieve this. I must tell you that setting it up requires you to have some familiarity with the terminal (which already comes installed on your computer). I've written a blog post on how I came about working on it and the iterative process that went behind it. You can read the post here [3]. The instructions to install Telltail can be found here [4]. It is a personal project of mine and is not affiliated to or promoted by any org. Hopefully with discussions and contributions we could add support for more OSs.

Show HN: Mirrorful – A developer-first way to implement designs faster https://ift.tt/N9EvDcF

Show HN: Mirrorful – A developer-first way to implement designs faster Hey HN! Mirrorful ( https://ift.tt/FbM51q3 ) is an open-source developer framework that helps front-end engineers manage their design systems. We’ve been building Mirrorful with the open-source community ( https://ift.tt/ExIU3k7 ) and wanted to share our beta with you. Check out our online demo to get the idea: https://ift.tt/r2kpsVn . Design systems can be thought of as the “building blocks of your app” which makes me think of Lego bricks. Mirrorful helps you manage your codebase’s Lego bricks and ensure that they are consistent across all of your apps and platforms. We saw as product engineers how hard it is to get code to match Figma mock ups. High-quality design is a competitive advantage, so getting your UI pixel perfect can matter a lot, but is time-consuming and tedious. When we worked for large public companies, we saw that good component libraries help, but engineers are often still dealing with tweaking small design decisions. There are a lot of inefficiencies. We also worked at a small startup and saw what it was like to not have a design system. No design system led to copy pasta code, and days of back-and-forth on simple things like “what hex should i be using for the hover state?” Design systems are tricky to get right. Picking an out-of-the-box solution is easy to begin with, but one day you’ll be cursing yourself due to lack of flexibility (we did!). On the other hand, creating a design system from scratch is super time-consuming even for the best frontend engineers. Mirrorful is our way out of this dilemma. Mirrorful is completely open-source and written in Typescript. We’re starting with basic design elements—commonly called “design tokens” — such as colors, typography, and shadows, but have plans to expand our scope into more complex components. As frontend engineers ourselves, we wanted a tool that lives in code but is visual. It had to be super easy to set up, but also prepare you for scale so you and/or your team don’t end up copy-pasting everywhere. We decided to make it an NPM package ( https://ift.tt/H9SWiFP ) that runs a localhost editor and exports out your design tokens into any configuration you want: .js, .ts, .css, .scss, .json. It’s lightweight with no design system lock-in. Our product is completely self-serve: just install our NPM package. If you run Mirrorful locally, a visual dashboard will pop up at localhost:5050 that lets you manage your theme and export various configuration files directly into code. Pricing is similar to other open-source companies—we charge for cloud-hosted features and for premium components. We’ve built open-source/open-core projects before and love interacting with contributors from all over the world. If anyone has any opinions on what we’re building, we’re all ears. Check us out at mirrorful.com and at github.com/Mirrorful/mirrorful and give it a shot! https://ift.tt/ExIU3k7 March 29, 2023 at 11:19PM

Show HN: go-nbd – A Pure Go NBD Server and Client Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :) https://ift.tt/H1AjBGM March 30, 2023 at 12:23AM

Show HN: PoachMe.dev, Reclaim Your Time https://ift.tt/lXEm6ud

Show HN: PoachMe.dev, Reclaim Your Time A couple of months ago, I posted about my stealth startup on HN and got a lot of friendly help and signups so I'm officially launching today to a wider audience. All of the features highlighted here are "FREE" (we just take a cut from your scheduled recruiter calls) PoachMe.dev is your one stop shop to being paid for the time you spend with recruiters on finding a job. From the hiring manager, to the recruiter, to the HR team cutting you an offer letter, every single person in the chain is getting paid while a candidate gets to pretend their money and time and resources aren't dwindled every time they take an interview so this turns it back on it's head. Have you ever received a random message asking for a random technology you don't have while also claiming "you're a perfect fit"? Send them a pre-composed "reply template message" from PoachMe ("Great. Please book a slot on my calendar and we can chat more about this. You'll receive my resume upon confirmation of the booking. https://ift.tt/V7MjSxu ") so they can schedule and pay for your time. You will be surprised how many great recruiters will blatantly tell you that you are not worth your time as soon as they're asked to pony up even $100/hr while making an easy 10k for placing you at a company. If your skills have value, you can cut through the recruiter chaff and get to the recruiters who are actually easy to work with in one easy step. After we built this core feature, we've branched out to creating a career snapshot (https://ift.tt/MQ7uNFY) which allows you to showcase your skills in one single screen without it being a resume and have started work on a virtual business card you can update and flash unto NFC cards so you have a digital business card you can carry around with you ( https://ift.tt/6MniUVJ ) Sign up today using the following limited signup code ( https://ift.tt/a47jrEU ). Although I am sure I am able to scale this startup to any size, limiting signups is a super easy way to not get HN-hugged-to-death. https://ift.tt/DMVNgex March 28, 2023 at 04:15PM

Show HN: KGraph, a GPU-accelerated graph plotter Have you ever lost your mind at Desmos or Geogebra for occasionally being so god-damn slow and laggy? I have and, as a result, decided to make my own, GPU-accelerated (webgl2) graph plotter that renders equations, shaded plots, etc. with butter-smooth framerates. Equations we are used to think as unplottable (with usable real-time performance), like for example `e ^ (sin(x) * x ^ 2 * cos(y)) = cos(e ^ (x * y))`, will render just as smoothly [0] as something simple, like `y = x ^ 2`. Goals: * Rendering (almost) any equation without performance problems * Enabling acquiring new insights from being able to closely interact with complicated equations * Having an intuitive, easy-to-use and not-buggy interface Non-goals: * Being a general-purpose CAS software KGraph is under active development, and features such as parametric equations are coming in the near future!

Show HN: FTX Creditor – Confirm that the bankruptcy court has your claim https://ift.tt/rWKm41y

Show HN: FTX Creditor – Confirm that the bankruptcy court has your claim FTX Creditor is the easiest way to confirm that the bankruptcy court knows about your claim. Background: Last week, FTX published 1.3M anonymized user accounts in a Schedule F filing that lists the unsecured creditors they know about. 1.3M is a huge number, but it may be less than half of the total users FTX had. If your account is not listed, file a proof of claim with the bankruptcy court, or they may not treat you as a creditor (Federal Rules of Bankruptcy Procedure: Rule 3003). The data was uploaded as a series of PDFs, which makes it hard to find your claim, especially if you don’t remember the exact amounts you had and have to fuzzy match with cmd+f! We built FTX Creditor so that you can find your claim with the information you have. Features: - Find claims by: - Assets. If you remember having 4-5 BTC, 10-20 ETH, 0-100 SOL, you can filter 1.3M claims down to 4. - USD value. The face value of a claim is the account value on November 11, the day FTX filed for bankruptcy. You can exclude “Sam Coins” from the value calculation. The court may ignore the value of assets closely associated with SBF, such as FTT and SRM. - Customer code. - See the court document a claim was listed in. - Subscribe for notifications about events that may impact your claim, such as when the court sets the deadline to file a proof of claim. - Search for terms across all public court filings. Future Work: - Creditors who are interested in selling their claims can receive offers from buyers. - Explore aggregate statistics across accounts and assets. - FAQ on the most relevant parts of the bankruptcy process. FTX creditors, we got this! https://ift.tt/qdhEuXs March 25, 2023 at 04:42AM

I have often found that when I say those words, is that I have to explain what advanced materials are. But I will skip that for this audience. Perhaps what you didn't know is that this is a $2 trillion industry, but over 99% of it remains offline. Alinor enables, scientists, engineers, and researchers to focus on what they do best: solving the world's biggest problems, by working on the cutting edge of materials and physical science. While we focus on selling their martials and enabling them to reach wider adaption. Alinor covers everything from initial inquiry to final invoice and everything in between. We do believe that nearly all problems the world is facing can be solved by advanced materials. Happy to answer any questions you might have, including what are advanced materials, just don't ask me to explain it in Arabic. Or maybe do that, I need to practice it more anyways! https://alinor.io/ March 24, 2023 at 04:07PM

Show HN: Datapane – A new way to build reports, dashboards, and apps in Python Hello HN! We’re Leo and Mandeep, founders of Datapane ( https://datapane.com ). We're building a way to create reports, dashboards, and web apps from your existing data using Python. Think of it as a combination of React and htmx, specifically designed for the Python data stack. Our GitHub is https://ift.tt/l3WSjIs and you can try building a report or app in ~2 minutes on Codespaces: https://ift.tt/GxFCLqW We started building Datapane at our previous start-up, where we struggled to deliver ML model results to clients. Much to our surprise, the data science took less time than repeatedly creating reports by copying and pasting plots into PowerPoint decks. It seemed absurd that we had to switch to PowerPoint or legacy BI tools like Tableau to share, and our initial goal was to programmatically generate reports using the datasets and plots we had in Python. To enable this, we started hacking on a Python-based UI framework for constructing HTML views from data-centric blocks – like plots, data tables, and layout components. You can export these to standalone HTML files, or host them as a web app on somewhere like GitHub Pages or Fly.io. We recently also added the ability to connect Python functions to forms and front-end events so you can build web apps which run backend code. We handle the entire network and RPC layer, so you only need to write plain Python functions that take parameters and return other blocks. You can check out an example of the code to create a simple app: https://ift.tt/6e75cBW... Datapane’s philosophy is pretty different from other products in the space. We wanted to keep things simple, but avoid the footguns our users faced with frameworks like Streamlit, where the reactive/network-aware model was hard to move beyond an MVP or POC. For backend interactivity, we believe the original web got a lot right, and unlike reactive models which rely on websockets, Datapane is unashamedly request/response. This takes inspiration from HTTP and our own experiences with htmx, which offers an elegant way to add interactivity to HTML. Under the hood, we actually compile down to a (gasp!) XML-based hypermedia format, akin to HTML, but tailored specifically for constructing data UIs. The result is that not every change in your app requires a server round trip, as much of it can be pre rendered and most interactivity happens on the client-side. In addition to improving performance, this also makes running in production become 10x simpler. This separation between the view and backend compute also makes Datapane modular. If our app server isn’t a good fit for your use-case, serve Datapane views from the web-framework of your choice (we’ve been hacking on serving views from Django). Want to compute blocks from inside Airflow or generate them on a schedule or from a webhook? Computation can happen out of band of the UI. You can even build and host apps from inside of Jupyter, where you can preview blocks live and convert notebook cells to blocks in your view. We currently offer a hosting platform on https://datapane.com for sharing reports publicly (free) or with your team (paid), and will be adding serverless app hosting support to it in the next few weeks. Our ultimate goal is to create an open-source toolkit for building data products across the entire stack – from reports, to dashboards, to full-stack apps – all using 100% Python. You can see a few we’ve built already in our gallery: https://ift.tt/cVzWKGO We’d love to hear your feedback. Thanks! March 23, 2023 at 09:50PM

Show HN: Dungeon Map Doodler Beta - Free online map drawing tool This is a D&D map making tool I've been working on for a while now, but I just added some new features to the beta that I think HN users might find neat. When building a world map, you can use "Dynamic Brushes" to draw organic looking terrain. This is achieved entirely with svg filters and javascript canvas, no fancy libraries or anything. This came with a pretty large rewrite of some of the underlying code, so I'm sure there's a number of bugs I haven't come across, but I'd love to hear your opinions on it! https://ift.tt/NFwXGRD March 23, 2023 at 04:18AM

Show HN: Zapier universal API (using natural language) https://ift.tt/L87hxIz

Show HN: Zapier universal API (using natural language) Hey HN! We launched Zapier way back in 2012 on HN: https://ift.tt/cqRebUM and thought we'd return home to announce something special and hopefully exciting :) We are trying to finally live up to the "API" in our name with Zapier's first universal API: Natural Language Actions – https://ift.tt/Wn2cioU API docs – https://ift.tt/V8qLivu (to be fair, we have published APIs before that can access Zapier data, but never before one devs can use to directly call the 5k+ apps / 20k+ actions on our platform) For example, you can use the API to: * Send messages in Slack * Retrieve a row in a Google Sheet * Draft a reply in Gmail * ... and thousands more actions with one universal API We optimized NLA for use cases that receive user input in natural language (think chatbots, assistants, or any product/feature using LLMs) -- but not strictly required! Folks have asked for an API for 10 years and I've always been slightly embarrassed we didn't have one. We hesitated because we did not want to pass along our universe of complexity to end devs. With the help of LLMs we found some cool patterns to deliver the API we always wanted. My co-founder/CTO Bryan did an interview with Garry on YC blog with more details: https://ift.tt/NTWvEFM... We also published a LangChain integration to show off some possibilities: * Demo: https://www.youtube.com/watch?v=EEK_9wLYEHU * Jupyter notebook: https://ift.tt/mI1NDun We know the API is not perfect but we're excited and eager for feedback to help shape it.

Show HN: Watermelon – GPT-powered code contextualizer Hey there HN! We're Esteban and Esteban and we are looking to get feedback for the new version of our GPT-powered, open-source code contextualizer. We're starting with a VS Code extension that indexes information from git (GitHub, GitLab, or Bitbucket integrations available), Slack and Jira to explain the context around a file or block of code. Finally, we summarize such aggregated context using the power of GPT. As devs we know that it's very annoying to look at a new codebase and start understanding all the nuances, particularly when the person who wrote the code already left the company. With this problem in mind, we decided to build this solution. You'll be able to get into "the ghost" of the person who left the company. Soon, we will also be building a GitHub Action that does the same thing as the VS Code extension but at the time of creating a PR: Index the most relevant information related to this new PR, and add it as a comment. This way we will provide context at one more moment, and also, we will be making the IDE extension better. Here's our open source repo if you also want to check it out: https://ift.tt/pohDI9T Please give us your feedback! Thanks. https://ift.tt/nluvITV March 22, 2023 at 12:39AM

Show HN: Great Books Homeschool beta program https://ift.tt/UHIZsVn

Show HN: Great Books Homeschool beta program I built this customizable literature-based K-12 homeschool curriculum, based on my experience as a homeschool parent. It's designed especially for intellectually curious kids who love to read. One of the main benefits of homeschooling is the ability to design customized programs of study that let kids learn at their level of challenge in each subject. But since designing custom curricula from scratch requires a huge time commitment and familiarity with children's literature and academic materials, most homeschooling parents don't take advantage of this potential and instead opt for prepackaged curricula. Great Books Homeschool eliminates a lot of the work involved in designing a complete and rigorous curriculum for homeschooled students. The website generates a default program of study for each student, then helps parents customize it. Transcripts and other records are generated automatically. Pricing is normally subscription based, but we're offering complimentary access for twelve months to the first 50 users who sign up for our beta testing program. In return, beta testers are requested to complete a monthly questionnaire about their experience with the curriculum. If you would like to participate in the beta testing program, please first create a free trial account at https://ift.tt/bUPXCua .

Show HN: I want to change how people buy health supplements https://ift.tt/DKC7S4o

Show HN: I want to change how people buy health supplements I made a table where you can find out the source/location of factory for where health supplements are made. Then, I spent a year reading product labels so you can save time and money when buying supplements. This is that update. This is still a work in progress but it functions fine. My previous post was a simple database of company data showing ingredient sourcing/location. That took 10 days, this has taken me close to 9 months. BackOfLabel is an extension of that initial interest with dosage information at the product & ingredient level. This update allows sorting by many more attributes at the product level (for 4000+ products at the moment) of manually scraped data. Now, for instance you can sort by specific types of ingredient - eg. filter by magnesium glycinate , magnesium orotate or any combination. eg. find ubiquinol or ubiquinone, two forms of coenzyme q10. This is useful for consumers but also companies seeking competitor analysis. You are able to filter products by – Ingredient – Filter by liquid, tablet, capsule, powder & more – Browse by UPC Code – Dosage Information – No. Individual Serving – No. Manufacturer Serving – Total Dosage For example You can also search by type of protein powder - eg. search for whey protein powder and find the dosage information for many products instantly. It frustrates me and I think the way that people buy supplements is wrong. And they don't know any better because there are incentive structures that keep them in the dark. This is a small effort to combat the misleading labeling and lack of regulation in the industry. full disclosure - i've provided a generic affiliate link in the table that means i earn a small percentage (5%) of total cart if you purchase through the link note: browse on desktop to filter & sort https://ift.tt/ZrBvdIQ March 19, 2023 at 08:31AM

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News https://ift.tt/Pb6Oynl

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://ift.tt/e2GBXFu The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: https://ift.tt/e2GBXFu About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community ( https://ift.tt/we7QVWl ). Quality News has been created based largely on this feedback. Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score. We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one. We look forward discussing our approach with you!

Show HN: Chainloop, A Software Supply Chain Attestation solution devs won't hate https://ift.tt/CI1cRvn

Show HN: Chainloop, A Software Supply Chain Attestation solution devs won't hate Hi, my name is Miguel and I am very happy to share what's been months worth of work :) The project has rough edges for sure, but any early feedback, comments or concerns are appreciated! === The Problem === You work on the Security and Operations (SecOps) team in charge of your organization's Software Supply Chain Security. You feel pretty good about the state of things already, your developer teams are signing their commits, deliverables, scanning for vulnerabilities,… Life is good! Then you realize that you are not compliant with the latest security requirements. You get referred to slsa.dev and are told that you need to be at least level 3, whatever that means! Aha! I “just” need to implement an attestation and artifact layer in our Software Supply Chain, which you complete after a couple of months of work. Now to the easy part (or what you think). To make the developer teams adopt it. You quickly realize that standardizing best practices and security requirements is very hard. Development and SecOps team dynamics are clashy and poorly defined due to priorities mismatch. Also, from the developer's point of view, it’s very time-consuming and frustrating to pollute your CI/CD systems with convoluted, error-prone and complex processes to comply with the SecOps team. So there has to be a better way that satisfies both sides... === The Solution === Enter Chainloop. You can think of it as an API for your organization's Software Supply Chain that both parties can use to interact effectively to meet their mismatched priorities. SecOps teams regain security compliance, visibility, standardization and control by having a mechanism to define and propagate attestation requirements. Developers, on the other hand, get jargon-free tooling that can be used to meet compliance with minimum friction and effort. === Give it a try === Eager for feedback from the community so please reach out. Happy to chat! Thanks! PS: You can see an attestation end-to-end demo here https://www.youtube.com/watch?v=Q_0dlBqKtIU&t=384s https://ift.tt/GCSN4R2 March 16, 2023 at 07:34PM

Show HN: Ingest data from your customers (Prequel YC W21) https://ift.tt/3XWr5H1

Show HN: Ingest data from your customers (Prequel YC W21) Hey HN! Charles here from Prequel (https://prequel.co). We just launched the ability for companies to import data from their customer’s data warehouse or database, and we wanted to share a little bit more about it with the community. If you just want to see how it works, here’s a demo of the product that Conor recorded: https://ift.tt/bihJDro. Quick background on us: we help companies integrate with their customer’s data warehouse or database. We’ve been busy helping companies export data to their customers – we’re currently syncing over 40bn rows per month on behalf of companies. But folks kept on asking us if we could help them import data from their customers too. They wanted the ability to offer a 1st-party reverse ETL to their customers, similar to the 1st-party ETL capability we already helped them offer. So we built that product, and here we are. Why would people want to import data? There are actually plenty of use-cases here. Imagine a usage-based billing company that needs to get a daily pull from its customers of all the billing events that happened, so that they can generate relevant invoices. Or a fraud detection company who needs to get the latest transaction data from its customers so it can appropriately mark fraudulent ones. There’s no great way to import customer data currently. Typically, people solve this one of two ways today. One is they import data via CSV. This works well enough, but it requires ongoing work on the part of the customer: they need to put a CSV together, and upload it to the right place on a daily/weekly/monthly basis. This is painful and time-consuming, especially for data that needs to be continuously imported. Another one is companies make the customer write custom code to feed data to their API. This requires the customer to do a bunch of solutions engineering work just to get started using the product – which is a suboptimal onboarding experience. So instead, we let the customer connect their database or data warehouse and we pull data directly from there, on an ongoing basis. They select which tables to import (and potentially map some columns to required fields), and that’s it. The setup only takes 5 minutes, and requires no ongoing work. We feel like that’s the kind of experience every company should provide when onboarding a new customer. Importing all this data continuously is non-trivial, but thankfully we can actually reuse 95% of the infrastructure we built for data exports. It turns out our core transfer logic remains pretty much exactly the same, and all we had to do was ship new CRUD endpoints in our API layer to let users configure their source/destination. As a brief reminder about our stack, we run a GoLang backend and Typescript/React frontend on k8s. In terms of technical design, the most challenging decisions we have to make are around making database’s type-systems play nicely with each other (kind of an evergreen problem really). For imports, we allow the data recipient to specify whether they want to receive this data as JSON blob, or as a nicely typed table. If they choose the latter, they specify exactly which columns they’re expecting, as well as what type guarantees those should uphold. We’re also working on the ability to feed that data directly into an API endpoint, and adding post-ingestion validation logic. We’ve mentioned this before but it bears worth repeating. We know that security and privacy are paramount here. We're SOC 2 Type II certified, and we go through annual white-box pentests to make sure that all our code is up to snuff. We never store any of the data anywhere on our servers. Finally, we offer on-prem deployments, so data never even has to touch our servers if our customers don't want it to. We’re really stoked to be sharing this with the community. We’ll be hanging out here for most of the day, but you can also reach us at hn (at) prequel.co if you have any questions!

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News https://ift.tt/evcqSFg

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://ift.tt/e2GBXFu The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: https://ift.tt/e2GBXFu About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community ( https://ift.tt/we7QVWl ). Quality News has been created based largely on this feedback. Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score. We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one. We look forward discussing our approach with you!

Show HN: Using GPT-3 and Whisper to save doctors’ time https://ift.tt/t5CkvxW

Show HN: Using GPT-3 and Whisper to save doctors’ time Hey HN, We're Alex, Martin and Laurent. We previously founded Wit.ai (W14), which we sold to Facebook in 2015. Since 2019, we've been working on Nabla ( https://nabla.com ), an intelligent assistant for health practitioners. When GPT-3 was released in 2020, we investigated it's usage in a medical context[0], to mixed results. Since then we’ve kept exploring opportunities at the intersection of healthcare and AI, and noticed that doctors spend am awful lot of time on medical documentation (writing clinical notes, updating their EHR, etc.). Today, we're releasing Nabla Copilot, a Chrome extension generating clinical notes from video consultations, to address this problem. You can try it out, without installation nor sign up, on our demo page: https://ift.tt/bSNv9hG Here’s how it works under the hood: - When a doctor starts a video consultation, our Chrome extension auto-starts itself and listens to the active tab as well as the doctor’s microphone. - We then transcribe the consultation using a fine-tuned version of Whisper. We've trained Whisper with tens of thousands of hours of medical consultation and medical terms recordings, and we have now reached an error rate which is 3× lower than Google's Speech-To-Text. - Once we have the transcript, we feed it to a heavily trained GPT-3, which generates a clinical note. - We finally return the clinical note to the doctor through our Chrome extension, the doctor can copy it to their EHR, and send a version to the patient. This allows doctors to be fully focused on their consultation, and saves them a lot time. Next, we want to make this work for in-person consultation. We also want to extract structured data (in the FHIR standard) from the clinical note, and feed it to the doctor’s EHR so that it is automatically added to the patient's record. Happy to further discuss technical details in comments! --- [0]: https://ift.tt/YbNwkWj March 14, 2023 at 10:16PM

Show HN: PixelForge.art – Leveraging Whisper to verticalize 16/9 YouTube videos Hi there! I've been a YouTube content creator during few years (50k subs, ~5M views) and I realized that many creators on the platform have their content stolen and republished on TikTok, Instagram Reels or YouTube Shorts for monetization purposes. I built PixelForge to tackle this problem. The tool allows content creators to work on their horizontal video as they usually do. But once the video is published, they can quickly generate tiktoks/shorts/reels without having to go through the tedious process of video editing again. https://pixelforge.art March 14, 2023 at 11:19PM

Show HN: Safe Data Changes in PostgreSQL https://ift.tt/Qui3Ax7

Show HN: Safe Data Changes in PostgreSQL Hi HN, we're excited to share our open source tool with the community! We previously posted here with the tagline “real-time events for Postgres” [0]. But after feedback from early users and the community, we’ve shifted our focus to working on tooling for manual database changes. We've consistently heard teams describe challenges with the way manual data updates are handled. Seemingly every engineer we spoke with had examples of errant queries that ended up causing significant harm in production environments (data loss/service interruptions). We’ve seen a few different approaches to how changes to production databases occur today: Option 1: all engineers have production write access (highest speed, highest risk) Option 2: one or a few engineers have write access (medium speed, high risk) Option 3: engineers request temporary access to make changes (low speed, medium risk) Option 4: all updates are checked into version control and run manually or through CI/CD (low speed, low risk) Option 5: no manual updates are made - all changes must go through an internal endpoint (lowest speed, lowest risk) Our goal is to enable high speed changes with the lowest risk possible. We’re planning to do this by providing an open-source toolkit for safeguarding databases, including the following features: - Alerts (available now): Receive notifications any time a manual change occurs - Audit History (beta): View all historical manual changes with context - Query Preview (coming soon): Preview affected rows and query plan prior to running changes - Approval Flow (coming soon): Require query review before a change can be run We’re starting with alerts. Teams can receive Slack notifications anytime an INSERT, UPDATE, or DELETE is executed from a non-application database user. While this doesn’t prevent issues from occurring, it does enable an initial level of traceability and understanding who made an update, what data was changed, and when it occurred. We’d love to hear feedback from the HN community on how you’ve seen database changes handled, pain points you’ve experienced with data change processes, or generally any feedback on our thinking and approach.

Show HN: APIRank.dev – we crawled and ranked 5651 public APIs from the Internet https://ift.tt/IBoyaNJ

Show HN: APIRank.dev – we crawled and ranked 5651 public APIs from the Internet tl;dr we at Escape (YC W23), we scanned 5651+ public APIs on the internet with our in house feedback driven API exploration tech, and ranked them using security, performance, reliability, and design criteria. The results are public on https://apirank.dev . You can request that we index your own API to the list for free and see how it compares to others. Why we did that? During a YC meetup I spoke with a fellow founder that told me how hard it was to pick the right external APIs to use within your own projects. I realized that most of what we build relies on public APIs from external vendors, but there was no benchmark to help developers compare and evaluate public APIs before picking one. So we decided to do it ourselves. Say hi to apirank.dev. Why ranking public APIs is hard? Automating Public API technical assessment is a tough problem. First, we needed to find all the public APIs and their specifications - mostly OpenAPI files. We used several strategies to find those: - Crawl API repositories like apis.guru - Crawl Github for openapi.json and openapi.yaml files - A cool google dork Those strategies enabled us to gather around ~20.000 OpenAPI specs. Then lies the hard part of the problem: We want to dynamically evaluate those APIs' security, performance, and reliability. But APIs take parameters that are tightly coupled to the underlying business logic. A naive automated way would not work: putting random data in parameters would likely not pass the API's validation layer, thus giving us little insight into the real API behavior. Manually creating tests for each API is also not sustainable: it would take years for our 10-people team. We needed to do it in an automated way. Fortunately, our main R&D efforts at Escape aimed to generate legitimate traffic against any API efficently. That's how we developed Feedback-Driven API exploration, a new technique that quickly asses the underlying business logic of an API by analyzing responses and dependencies between requests. (see https://ift.tt/doO0y7r ) We originally developed this technology for advanced API security testing. But from there, it was super easy to also test the performance and the reliability of APIs. How we ranked APIs? Now that we have a scalable way to gather exciting data from public APIs, we need to find a way to rank them. And this ranking should be meaningful to developers when choosing their APIs. We decided to rank APIs using the following five criteria: - Security - Performance - Reliability - Design - Popularity Security score is computed as a combination of the number of OWASP top 10 vulnerabilities, and the number of sensitive information leaks detected by our scanner The performance score is derived from the median response time of the API, aka the P50 The reliability score is derived from the number of inconsistent server responses, either 500 errors or responses that are not conform with the specification The Design score reflects the quality of the OpenAPI specification file. Having comments, examples, a license, and contact information improves this score The popularity score is computed from the number of references to the API found online If you are curious about your API's performance, you can ask us to index your own api for free at https://ift.tt/F9ZdH8L https://apirank.dev/ March 10, 2023 at 01:43AM

Show HN: DemandHunt – Make something people want https://ift.tt/0l5GucW

Show HN: DemandHunt – Make something people want Hi HN! I've been working on a small project called DemandHunt. Basically I aggregated problems in niche communities so that you as an entrepreneur can take inspiration. The background is that I've worked with a number of startups and I've found that many entrepreneurs already have a technology or solution in mind and work backwards to find the people with the problems to solve. This is YC's "Solution in Search of a Problem" problem, and my understanding is that it's typically better to work the other way around so you can build the right solution for the problem you find instead. Thus I figured maybe some hacker types like me would appreciate reading about problems in their interest areas so that they can get the ball rolling from the right direction. I went and did some reading in some niche Reddit communities and manually aggregated the user posts into tangible problems that might inspire you. I'm curious to see if this is interesting or useful to anyone here! Let me know what you think, if you want me to target your interests, or updates, or anything :) https://ift.tt/kmbglpz March 10, 2023 at 12:12AM

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT https://ift.tt/U5ueVw6

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I asked for a Dewey classification... and it worked. So I replaced a few days of fiddly work with 3 cents per inference and an overnight data run. My takeaway is that I'll be using LLMs as function call way more in the future. This isn't "generative" AI, more "programmatic" AI perhaps? So I'm interested in what temperature=0 LLM usage looks like (you want it to be pretty deterministic), at scale, and what a language that treats that as a first-class concept might look like. https://ift.tt/ZxphrFW March 9, 2023 at 03:28AM

Show HN: Plato – Airtable for your SQL database https://ift.tt/dHTxQV0

Show HN: Plato – Airtable for your SQL database Hi! I've been a member of HN for fifteen years so today I'm very excited to share Plato. Plato is an Airtable-like interface for your Postgres or MySQL database. It's an admin panel for devs and non-devs alike to manage your DB. We see teams use Plato for customer support, customer success, ops, etc.. We built Plato because we think more people should be able to build and extend internal tools. We thought it was strange that even though low-code is supposed to democratize development, all of the low-code internal tool builders are marketed to engineers! Airtable is a familiar UI that fits the relational model well, so we've been inspired by their work. Even the engineers on our team use Plato quite a bit, since it's often easier than spinning up a SQL prompt. Some features: - Postgres and MySQL support - Visual query controls (sorts, filters, hiding columns). No SQL. - Joins by "expanding" foreign keys - Virtual columns for tracking new data - Auto-generated backlinks for one-to-many relationships - Read-only locking for individual tables - Virtual tables for sharing new views with your team Plato today works on databases with a public IP (just whitelist our IP to connect), but we're soon rolling out an on-prem version. We can also set up an SSH tunnel for you if you contact us at team@plato.io. We'd love to hear your feedback! Thanks. - Michael https://ift.tt/MeOTN9m March 8, 2023 at 11:50PM

Show HN: Versionfeeds – Custom RSS feeds for releases of your favorite software https://ift.tt/UEvmqB8

Show HN: Versionfeeds – Custom RSS feeds for releases of your favorite software Hi HN! I am quite excited as this is my second product, launched today: Versionfeeds. https://ift.tt/tydqSE4 What is Versionfeeds? I was quite annoyed by the fact that I had no central place where I could see all the software releases. I use software a lot, be it at my job, to build my side projects, or tools hosted on my NAS at home. It's literally dozens, if not hundreds of tools, packages or even programming languages. And most of them receive updates regularly. That is why I built Versionfeeds. It allows me to bundle all the releases for the software I need and love, into one dedicated feed. At the moment, all public repositories on Github and Gitlab are available. You can also search on npm (Javascript) and Packagist (PHP) for your software. More providers will come soon. The feeds adhere to the Atom standard and can be consumed with any feed reader. If maintainers use markdown in their release notes, it will be converted to HTML. Any feedback, wishes and ideas are welcome. Please share your thoughts with me. <3 March 8, 2023 at 11:02PM

Show HN: Co-locating Debian Bullseye with an evil maid https://ift.tt/yp40AlL

Show HN: Co-locating Debian Bullseye with an evil maid In order to facilitate the secure co-location of a server, I looked into protecting a Debian Bullseye system from evil maid attacks. In addition, since I've enjoyed using ZFS for some time, I decided to rely on a natively encrypted ZFS root file system. Basically... I'd like to take a system containing sensitive information, box it up, and drop it in the mail without worrying about losing it or having it wind up in the wrong hands. A couple of things became clear while researching how to do this. First, there should be little chance that a rogue data-center admin can insert malicious software. When the system reaches the data center and gets powered on we should be confident that it's running our software completely unmodified. As I understand things, Secure Boot is designed to help with this and therefore should be enabled. However, by relying on Secure Boot alone, there will be no remote method of knowing that it hasn't been disabled until after the ZFS pass-phrase is provided to the initramfs via dropbear. At that point it's too late. An evil maid could have already subverted dropbear, for example, and just now stolen the pass-phrase. To avoid this I realized that a second requirement of using a TPM device to automatically unlock the ZFS root was in order. TPM devices have the ability of "sealing" data to so-called Platform Configuration Registers (PCR). This feature allows the data to be accessed only if the "measured" system state matches some original expected state. The TPM can fully start the system unattended but, if anything's unexpectedly meddled with, act like a tripwire requiring the pass-phrase to be typed in manually. If we ssh in and reach dropbear requesting the pass-phrase, we'll know that we either need to update our sealed data after a grub/kernel/initramfs update... or someone's been messing with our start up code. This window of opportunity will be too small for an evil maid to take practical advantage of. This sounded like the right track and I set out to try and configure both, Secure Boot and TPM unlocking of an encrypted ZFS root. I thought it'd take a few hours at most but it actually turned out to be a fair challenge. After a few failed attempts I started tenaciously documenting every avenue. Ultimately I developed helper scripts that can reproduce the configuration should the time come to actually ship a machine out the door. I'm reasonably satisfied with the outcome. However, the scripts haven't been reviewed and neither has the overall process itself. There were a lot of guides I followed that contained typos, bugs, dubious information or simply different requirements. I'm not sure everything is exactly "bullet-proof" for this show HN. For example, I'm beginning to wonder if Secure Boot is necessary and if the TPM alone is sufficient. So naturally, comments and criticisms regarding everything are greatly appreciated. The script files can be found here: https://ift.tt/EZX7V6T and here: https://ift.tt/n3AzaBb Finally, I hope this effort will be useful to others facing similar needs. March 8, 2023 at 05:19PM

Show HN: Improve essay writing skills with ChatGPT https://ift.tt/f4uvWnZ

Show HN: Improve essay writing skills with ChatGPT Hey there folks, today I want to share with you how I came up with a ChatGPT-based service to improve essay writing skills, particularly for tests like PTE (Person Test of English) and IELTS. Now, let me just say upfront that I'm not a huge fan of writing essays. But I know that practice makes perfect, so I force myself to write them every day in the hopes that they'll eventually become easier. However, one of the biggest challenges I face is that I don't always get immediate feedback on my writing. I have a weekly call with my English teacher, which is great, but it means that I have to wait to get feedback on my mistakes. And in the meantime, I keep making the same errors over and over again, which can be frustrating and slow down my progress. That's where ChatGPT comes in. After some experimentation with prompt engineering, I discovered the one that allows me to get instant feedback on my writing. The AI checks things like structure, complexity, vocabulary, and so on, meaning that the main problem was solved. But that's not all. I also realized that ChatGPT could help me take my writing skills to the next level. One day, I was curious to know how a native English speaker would express my thoughts. How close was I to perfect English writing? So I fed my essay into ChatGPT, explained how the perfect essay should be written, asked it to rewrite it as a native speaker would, and saved the meaning at the same time. And let me tell you, I was blown away by the level of English that ChatGPT produced. I put these 2 features (personalized feedback and rewritten essay) into the website and now I am asking for your feedback. There is no need to sign up, just put an essay, and press the button. https://ptewithai.com/ March 8, 2023 at 03:37AM

Show HN: Can I Compost It? – Find Out What Goes in Your Compost Bin https://ift.tt/jm4JHkh

Show HN: Can I Compost It? – Find Out What Goes in Your Compost Bin Composting is a great way to reduce waste and nourish your garden, but it can be confusing to know what items can and can't be composted. That's why I created canicompostit.com - a simple and fast way to find out. With Can I Compost It?, you can quickly search for any item and get a simple "Yes" or "No" answer, along with some tips on how to compost it properly. My real-time database is constantly updated with new items (and if you search for something and it's not in it, you can suggest it, then I research the item and add it to the DB). I included compost categories (brown or green) and references when applicable. I first had the idea for this webapp years ago, and after some initial development, I posted it on Reddit (here: https://ift.tt/ws1PpNx ...). The response was overwhelmingly positive, with people asking for additional features and thanking me for creating a useful tool. I took their feedback to heart and rebuilt the webapp from the ground up using Nuxt.js, Tailwind, and a Google Sheet database. The result is a lean and efficient webapp that's easy to use and navigate. Can I Compost It? is free to use and ad-free. Keisaku said in the Reddit thread: "This is the kindve site that makes me want to put a dedicated tablet in the kitchen." Now this is something that motivates me! Admittedly, this is a one stone two bird project: I'm trying to create something useful and at the same time, use it as an excuse to hone my dev skills. Next up, I'm working on a mobile app that will allow you to snap a picture of an item and instantly find out if it's compostable. My goal is to make composting as easy and convenient as possible. If you find it helpful, please share it with others who might benefit from it. Thank you for your support! Balint https://ift.tt/gY2uoEw March 7, 2023 at 10:20PM

Show HN: Simple Log Alerts to Slack https://ift.tt/EZy6Id1

Show HN: Simple Log Alerts to Slack There are many log alerting systems on the market. The best known is probably Datadog. There’s also Logtail, Papertrail, Splunk, Logstash and others. These are well put together products with a host of great features, such as excellent UIs, sophisticated live searching via web interfaces and sometimes query languages and alerting. They require various levels of installation and they have costs, either through volume-based tiered systems or monthly payments. For a bootstrapped business, this can be problematic, for instance when a surge of logs - indicating a possible important problem that needs to be solved - pushes volume on to another tier. Should the “log ransom” be paid? Instead, I recalled from earlier times surely the simplest log watcher: Swatchdog [1]. It is rather venerable software. Its file history from its source download shows dates in 2015, but it was written much earlier - the 90s or possibly 80s by Todd Atkins [2]. We wanted to have alerts in Slack - the blog explains how we did it. In short: *very simply*. The code is available [3].

Show HN: Open-Source Alternative to Loom https://ift.tt/2pYc9zk

Show HN: Open-Source Alternative to Loom Hey HN, we're excited to introduce Sorbay - an open source alternative to Loom for creating and sharing screen recordings. With Sorbay, you can easily record your screen, camera, and microphone all at once. It is a complete solution that comes with its own backend service, allowing you to instantly share a link of your recording as soon as it is finished. The video is streamed directly to the backend service as the recording happens to make this possible. With both founders based in different countries, we needed a tool to quickly share screen recordings to keep us up to date or to ask for feedback. Meetings are cool if you need to discuss something deeply, but for almost everything else a quick recording works better. We had to settle for one of the proprietary solutions because none of the open source tools allowed us to quickly share something with each other. Doing the recording is one aspect, but having the ability to instantly share a link was crucial. Waiting on a 400mb video upload to a Dropbox is just too much interruption if you want to quickly share something. The tipping point for us to actually build this open source tool came via an interaction from one of our day jobs. A third party provider sent a screen recording full of confidential information and to make things worse, all of it was uploaded by them to a different third party service. We strongly believe that information like this should stay within a company, ideally on infrastructure that they control themselves. Having a fully integrated open source solution is the best way to go for this. Our goal with this first public release is to gather feedback. The critical code paths are working, but it is still a bit rough to use. We deliberately cut out all non-essential features, but have a clear roadmap on what we want to release this year. There are a couple of known issues like audio glitches, non-working videos in Safari and crashing binaries that we hope to fix in the coming weeks. Later this year, we plan on releasing a cloud hosted version of Sorbay that would let you connect your own S3 storage provider. Additionally, we will be releasing an on-prem option focused on features for enterprises (SSO, RBAC, compliance). Both the Sorbay Client and the backend service are completely open source. For licensing we choose the AGPLv3 throughout the stack. The client is built with Vue.js on top of Electron. The use of Electron might be a bit controversial here on Hackernews but given the resources we currently have that was the only way that allowed us to get a working client out on all major platforms. The backend service is realized with Django. We use Keycloak for authentication and Minio for S3 compatible storage. All of this is run alongside Postgres and Redis, running on Docker containers which are managed by Docker Compose. We invite you to try Sorbay for yourself and join us on our issue tracker[1][2], Slack channel[3] or here on HN. Thanks for checking out Sorbay!

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator https://ift.tt/tJ1G8zS

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator Hi HN! This is a simple text to entity-relation graph generator, powered by gpt-3 davinci model. The purpose is to feed it actual written data, to obtain a graph representation of entities and relationships mentioned in the text. Also, being able to identify entity attributes like gender, size, age ... My initial goal, was to make it able to process a large amount of text into a big single graph. The problem being the 4000 token limit the model has, I decided to take the approach of feeding the text in batches, and try to merge the incoming graph with the existing information each time. This is done by comparing the incoming node labels with those already in the graph, adding the new information to the existing nodes. This works somewhat, but sometimes entities get duplicated if they are mentioned slightly differently in the text. The comparation method could use some improvement clearly. A nice feature, is that you get to decide what types you want to extract. So if, for example, you are interested only in people, and companies in the text, you can tell the model to stick to that. You can also leave the types to the model discretion. Also, the application allows for saving / loading graphs to json files. These files can be used with Cytoscape Desktop Application, which is a nice side effect of using cytoscape.js. in the UI. I think tools like this can really be of help when going through dense documentation. To have a visual representation of the concepts, entities or whatever, can be really helpful in education, investigation, legal ... Would love to hear your thoughts on how this could be improved. https://ift.tt/dZsMJpx March 5, 2023 at 07:47AM

Show HN: Zipslicer, a library for loading LLM checkpoints on consumer hardware This is a low-level opensource library I developed for my own use and decided to share, as it makes it possible to process large checkpoints of neural networks without renting high-RAM instances, on a regular PC. It replaces torch.load() with a custom function that produces a dictionary that materializes tensors on the fly. Compared to other solutions it doesn't require sharding or re-encoding checkpoints and uses them completely as-is. It is a foundation to make it possible to run inference and compress language models and other large models one layer at a time - in principle, even one tensor at a time. I describe the rationale and technical details of the library's design in the blogpost: https://ift.tt/QB4thcS https://ift.tt/QG0pkug March 4, 2023 at 03:29AM

Show HN: Sort Any Awesome List by GitHub Stars https://ift.tt/Q1b4IyH

Show HN: Sort Any Awesome List by GitHub Stars As a CS undergrad, I self-taught many topics not covered by the school. Typically awesome list is where I started with. I spent my second half in college researching computer vision and machine learning. CVPR accepts over 2000 papers every year, not to mention arXiv. The awesome lists curated by the community usually serve as checklists when I was doing literature surveys. But since the number of the list items was overwhelming, I had to prioritize which papers to read first. Many of them had been uploaded to arXiv in the last few months, so I had no clue how many citations they would get. When learning web development, I also had difficulty finding the best package for the tasks like data validation and client-side routing. To make a decision, I had to browse through GitHub repositories or read the documentation. I wish I could have my awesome lists sorted, desirably by popularity. This led to the creation of my project: a web app that rearranges any awesome list with hints from GitHub stars. It may not work well when the list items do not contain links to GitHub repositories or pages, but it truly shines when most of them do. I hope this could help anyone else. P.S. I'm aware of a similar project ( https://ift.tt/qD6aRP7 ), a CLI application with more features. For example, it checks if any GitHub repository link exists on the linked website. https://ift.tt/i8TXdmR March 3, 2023 at 02:51AM

Show HN: Mathesar – open-source collaborative UI for Postgres databases https://ift.tt/4lGam9S

Show HN: Mathesar – open-source collaborative UI for Postgres databases Hi HN! We just released the public alpha version of Mathesar ( https://mathesar.org/ , code: https://ift.tt/ry2xUce ). Mathesar is an open source tool that provides a spreadsheet-like interface to a PostgreSQL database. I was originally inspired by wanting to build something like Dabble DB. I was in awe of their user experience for working with relational data. There’s plenty of “relational spreadsheet” software out there, but I haven’t been able to find anything with a comparable UX since Twitter shut Dabble DB down. We're a non-profit project. The core team is based out of a US 501(c)(3). Features: * Built on Postgres : Connect to an existing Postgres database or set one up from scratch. * Utilizes Postgres Features : Mathesar’s UI uses Postgres features. e.g. "Links" in the UI are foreign keys in the database. * Set up Data Models : Easily create and update Postgres schemas and tables. * Data Entry : Use our spreadsheet-like interface to view, create, update, and delete table records. * Data Explorer : Use our Data Explorer to build queries without knowing anything about SQL or joins. * Schema Migrations : Transfer columns between tables in two clicks in the UI. * Custom Data Types :: Custom data types for emails and URLs (more coming soon), validated at the database level.

Show HN: ChatGPT Bot Trained on Reddit Data https://ift.tt/icJDk8t

Show HN: ChatGPT Bot Trained on Reddit Data I'm heavily relying on Reddit for my online research, but there are many repetitive questions and recommendations on subreddits, so I trained a GPT bot on over 100k r/BuyItForLife comments and posts to embody the collective knowledge of this Reddit community (and soon many other subreddits). This could supplement Reddit and improve discussion quality. Currently, users often receive repeated answers or links to previous discussions. The tool would offer an initial answer and the option to post to Reddit if necessary. Some posts I answered with the bot: - Request Post: Dishwashers. What’s currently the best dishwasher for home use? - Bot Answer: https://ift.tt/art8Slv... - Request Post : Recommendations for hiking shoes? - Bot Answer: https://ift.tt/8BwV74u... ------------ It's far from perfect and comes with limitations: - Outdated information: I'll try to improve this by factoring in recency and some additional product information like prices, specs, etc, that I'm collecting. I also want to add more statistical significance to the results, e.g. by feeding in the amount of product recommendations over time. - Hallucination: As always with these bots, they sometimes make things up. More training data should help here. - Performance: Generating the answers is pretty slow and I'll look into improving this. Take it with a grain of salt and look at it as a fun experiment :) Would love to hear your feedback! https://ift.tt/caEnq0b March 3, 2023 at 12:32AM
