Show HN: Adzviser – Digital marketers' copilot for getting data [video] https://ift.tt/5q1EHu4

Show HN: Adzviser – Digital marketers' copilot for getting data [video] Hello friends - I spent the past 6 months building this search bar for marketers so that they can get their campaign performance data easier and faster. Currently they either have to manually pull those data from Google Ads, Facebook Ads, etc., or to use some connectors, such as Supermetrics/Fivetran, to automate the data pulling process and then build a reporting dashboard from it. I believe that those marketing data and reports can be "one search away". So I built a software prototype that 1) has OAuth2.0 connections to Google Ads 2) translates natural language prompt to Google Ads Query Language 3) generates table and visualization output Contact us: adzviser.com/contact-us https://www.youtube.com/watch?v=O7CWf5Kaypg May 1, 2023 at 10:07AM

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT https://ift.tt/BvMsA9D

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT We're back with another ShowHN! When we launched, you could text Jarvis AI using regular SMS messages from your phone. Since launching 3 weeks ago[1], we've introduced two new channels for using ChatGPT. Now you can use ChatGPT over SMS text message, iMessage for Apple-enabled devices, and via Email. It is super interesting to forward an email to Jarvis AI and see its thoughts on your email thread. It can help you brainstorm or it can suggest a reply to previous emails. 10 messages free forever, more volume is free over iMessage and Email for a limited time (until the HN hug of death!). You don't have to sign up or anything to try it. Just send a text to: +1 (855) 676-1two89. Thanks for checking this out. Many exciting features are coming soon to make this more than just a different interface to ChatGPT. We want to make AI accessible to more people, over more channels, with more useful things for your day-to-day. For medical professionals, we added the /diagnose command. Ask Jarvis "/diagnose 32 year old harsh cough" for example. Soon, we are adding features like /invoice for generating invoices and /remember for notes and reminders.

Show HN: Code-Narrator: Automating Documentation with GPT-4 https://ift.tt/ab36GPq

Show HN: Code-Narrator: Automating Documentation with GPT-4 As a solo developer on a sizeable project, I found myself facing the challenge of creating documentation, a task I admittedly do not enjoy. Fortunately, ChatGPT arrived just in time. After experimenting with it, I discovered that it generates high-quality documentation for code files, even better than what I could produce manually. This realization led me to develop Code-Narrator, a client that simplifies the documentation process. Code-Narrator ( https://ift.tt/Ohn3GAd ) utilizes GPT-4 to analyze your code files and automatically generate documentation. The tool is language-agnostic and has been tested with TypeScript, GraphQL, Solidity, C#, Kotlin, and more. As long as the files are in plain text, Code-Narrator should work seamlessly. The primary goal of Code-Narrator is to ease the documentation process for developers, transforming them from writers to editors. While developers are still responsible for verifying the accuracy of the generated documentation, the initial writing is handled by the AI. If GPT-4 produces incorrect documentation, it typically indicates that the code needs clarification, or a brief comment should be added to guide the AI. A general rule of thumb is that if GPT-4 cannot comprehend the code, it may be too complex for the next developer. However, Code-Narrator is constrained by GPT-4's 8192-token limit, which can be problematic for extensive code files. Those with access to the gpt-4-32k variant should expect better results. Upon its first run, Code-Narrator creates a configuration file by analyzing your project, and then prompts you to review it for accuracy. The key configuration aspects include the "include," "config_files," and "source_path" settings. In its second run, Code-Narrator generates documentation for your entire project. The process is time-consuming, taking approximately 45 minutes to complete from scratch. However, the tool is: - Flexible, allowing for the creation of custom pages such as How-To guides, tutorials, FAQs, READMEs, and other bespoke content. - Multilingual, supporting 25+ languages (as many as GPT-4 supports). - Versatile, capable of generating documentation in various formats (LaTeX, HTML, with the default being Markdown). For a demonstration on transforming a few lines into a How-To guide, watch this video: https://www.youtube.com/watch?v=uJtVCUOTkvw . Remember that brevity is key, as the more concise the input, the more GPT-4 can contribute. Code-Narrator also supports custom plugins, with tutorials available at https://ift.tt/pAv16ws... . In terms of size and cost, Code-Narrator consists of 45 files and 1712 lines of code. The total cost of generating documentation for the entire project is approximately $2.5, a significant savings compared to manual documentation. During the development of Code-Narrator, I noticed several benefits: - Improved function naming: Reading the generated documentation led me to revise vague or overly general function names, resulting in better code and documentation. - Concise input: Focusing on reducing the size of the input file (liquid) became a fun challenge, helping to optimize the process. - Enjoyable interaction: Working with ChatGPT proved more enjoyable than manually writing documentation, and the more I experimented, the better the results. - Minimal input for tutorials: I was pleasantly surprised by how little input was required to create How-To guides and tutorials using GPT-4. - Encouragement to refactor: The 8K token limitation may be restrictive, but it also encourages developers to refactor their code for improved readability and structure. As a prototype and proof of concept, Code-Narrator has some limitations. I'm excited to see where Code-Narrator goes from here, and your feedback is invaluable. Thank you for taking the time to explore this project! https://ift.tt/Ohn3GAd April 28, 2023 at 03:49PM

Show HN: GraphAr – An Open-Source File Format for Graph Data Archive/Exchange https://ift.tt/CGOiWK8

Show HN: GraphAr – An Open-Source File Format for Graph Data Archive/Exchange Hi, Hacker News! We're excited to announce the release of GraphAr, an open-source file format for archiving and exchanging graph data. The landscape of graph processing systems is fragmented, with various types of systems, including graph databases, graph computation systems, and GNN systems. However, currently, there is no common file format for efficiently storing and exchanging graph data while maintaining its schema and graph semantics. GraphAr is designed to address this issue by providing a simple, lightweight format for storing and exchanging graph data. GraphAr is a flexible and adaptable format that can be used across a variety of applications by decoupling the storage of metadata, adjacency, and properties. It is also designed to be efficient by leveraging existing formats such as ORC, Parquet, and CSV as much as possible. This makes it easy to integrate with existing data processing systems and provides a level of familiarity for users. Furthermore, GraphAr preserves the semantics of graphs and can maintain the schema of property graphs. This means that users can maintain the same graph structure across different systems, ensuring that the graph's semantics are not lost. We have developed both a C++ library for accessing and creating GraphAr files, and a Spark library for transforming data into and from GraphAr files. With these libraries, it's easy to work with GraphAr files in your existing Spark connectors or C++ projects. As GraphAr matures, we aim to move the project to a vendor-neutral venue, such as Apache, LF AI & Data. This will ensure that the project continues to be developed in an open and transparent manner, with contributions from a broad community of developers. To get started with GraphAr, check out our GitHub repository, where you'll find detailed documentation and examples of how to use the libraries. We welcome any feedback or contributions to the project. Let's make graph data archiving and exchange more efficient with GraphAr! https://ift.tt/QA2mRIf April 27, 2023 at 07:46PM

Show HN: Ordently – Consciously plan your day and your life https://ift.tt/jpgxfst

Show HN: Ordently – Consciously plan your day and your life I've been using a task management tool for the past 1 year that I built. A few months ago, I spent some time to make it more generic because my partner wanted to use it as well and she's been loving it ever since. Love her, but she's a bit biased. Firstly, this is a todo app for your life. Existing tools are built around how we work as employees in a company. With a company, all the habits, goals, vision and rituals are given to you in an employee handbook. The company is our coach, and in most cases, we listen and do as the coach says. Its easier to get things done in this environment. In our personal lives, we gotta figure out our goals, work on our habits and setup rituals. We're also more flexible, more forgiving on when we want to do certain things and more rigid on the others. The Daily Planner is central to that ideology, working with one off and repeatable tasks . You onboard with your day first, could be as simple as calling your mum or going on a walk or do yoga. As you get more comfortable, you start to consciously build a life that you want to live by creating rituals and setting goals as you get more confident. Personally, I haven't been able to get that through Todoist or Notion. https://ift.tt/5jzcvg0 April 26, 2023 at 02:51AM

Show HN: A website to generate Magic: The Gathering cards I created a website that utilizes OpenAI's LLM to generate realistic Magic cards based on a prompt. Using LLMs to generate Magic cards (or generate anything these days) is not new, but I've tried to put this together into a nice package and I am planning on making future improvements. You can generate some pretty flavorful cards depending on what prompt you provide. There are some issues since this is an early version. You will see cards that are just flat out incorrect or that do not make sense. I also will not guarantee the website will always work, so please be nice :) You will also notice the website domain name is a random one generated by Azure (if people like this, I may get a real one).

Show HN: Torb – make Kubernetes DevOps easier https://ift.tt/suvatDh

Show HN: Torb – make Kubernetes DevOps easier https://ift.tt/j1gaRWY Hey HN, about 9 months ago I was getting infrastructure set up for a project and it was taking way too long. It took hours before I was even able to begin working on the project itself instead of the infrastructure and it wasn't particularly pleasant. I got fed up and that's when I started thinking about how I could make it easier for people to develop with Kubernetes locally and then quickly deploy to a production environment in a consistent way that respects a set of best practices and leveraging some common infrastructure tools like Terraform and Helm under the hood. The result of this was Torb. The mission is to make it simple and easy for software engineers to create and deploy infrastructure on Kubernetes with best practices in place. For now I've been focusing on getting projects launched on an existing cluster, but I'd like to eventually help with bootstrapping clusters as well. I've been dog fooding this on my own projects for a bit now and have also had some friends who are using the tool and giving me feedback. April 23, 2023 at 04:01AM

Show HN: We built a ClickHouse-based logging service https://ift.tt/lpjLEnr

Show HN: We built a ClickHouse-based logging service Hey hn! I'm one of the co-founders of highlight.io, an open source monitoring tool. Today we're sharing a ClickHouse-based logging solution we've been working on. We wanted to showcase how we built it and share how you could try it out to give feedback. Since we started working on highlight.io, we've been hyper-focused on "cohesion", or ensuring that when you install your monitoring stack, all of the resources in that stack (user interactions, requests, traces, logs, etc.) are connected in a consumable way. We've written up more about our philosophy on this here [1]. We started building towards this by connecting your client-side app and your server-side exceptions with session replay and exception monitoring; i.e. if an error happened in a server-side app, we would make it easy (with session replay) to trace all the steps that a user took leading up to it. Especially for larger companies using highlight.io, the request to tie in logs came up repeatedly, and we wanted to build this with the same philosophy in mind. Now, you'll see client-side and server-side logs all in one place, brought together in the context of a user session, as well as logs in the context of an error. Like the rest of our stack, this project is written in Go and Typescript, and for log ingestion/querying, we're using ClickHouse [2]. Before deciding on ClickHouse, we were planning to use OpenSearch (an aws fork of elasticsearch [3]) for this part of our product, but as our traffic has increased, we encountered quite a few pains with write throughput for OpenSearch. After evaluating a few options, we eventually landed with ClickHouse (their cloud offering was icing on the cake), which has also proven to be much more cost-effective so far. Building with ClickHouse from scratch has been an exciting journey. Eric (the mastermind behind this project) wrote a blog post [4] on a handful of ClickHouse learnings we've gathered since starting the project. For those wanting to try out the product locally, you can run the following commands [5]: git clone --recurse-submodules https://ift.tt/BVFdxAS cd highlight/docker; ./run-hobby.sh; To send logs to highlight, you can use your own OpenTelemetry implementation [6] or use our SDKs [7] which provide lightweight wrappers over OTEL. Like the rest of highlight.io, we plan to make money from this with our hosted cloud offering. For those interested in trying out the cloud-hosted version, you can get setup at app.highlight.io. To open the floor for feedback, we would love to get some thoughts on what we've built so far. Beyond that, what are parts of a logging product you wish you had with your current setup?

Show HN: AI prompt-to-storyboard videos w/ GPT, Coqui voices, StabilityAI images https://ift.tt/ybk4cOC

Show HN: AI prompt-to-storyboard videos w/ GPT, Coqui voices, StabilityAI images I had 2 weeks off from work and wanted a pet project before heading back. With GPT and Generative AI in the news, I decided to chain multiple Al products together to build something really cool. I set my end goal to be: prompt-to-storyboard (aka fun videos generated purely via generative AI). There exists some prompt-to-video products, but I wanted to tell stories with audio as well. The end product takes an initial prompt and produces a series of images and audio files, which I then combine (with subtitles) into the final video. To showcase videos, there is a basic upvote/downvote leaderboard. Text | OpenAI https://openai.com/ Text is generated in a few high-level steps that I ask GPT to work through. These are all based on the initial user prompt, as such (ideally) indirectly controlled by the user. - Create a concept for a movie scene based on the prompt, including the theme and setting - Define each character in the scene - Define how each character looks - Define how each character sounds - Define 'frames' of the storyboard All of this textual information is defined in a JSON object I describe to GPT. I then take GPT's output and build the storyboard with the tools below. Voices | Coqui https://coqui.ai/ From the GPT output, I needed three major pieces of information to build voices in a way that I found satisfying: - Description of the voice - Description of the performance - Text of the actual dialog spoken Coqui has a product called 'prompt-to-voice', where you can describe how a character will sound and a custom voice is made for that character - this is how GPT defines the characters to use in the storyboard. As such, every voice is unique per storyboard. GPT will decide that a certain character is an "older man with a raspy voice", and I'll ask Coqui for that type of voice. In addition to this, in order to describe the performance, GPT outputs a basic emotion to summarize the line of dialog (happy, sad, angry, etc) - this is also sent to Coqui per audio clip generated. Images | Stability AI https://stability.ai/ While I originally setup the storyboard generator to use DALL-E due to already integrating with OpenAl for GPI, I found the cost prohibitive. As such, the images generated for the storyboards are from Stability Al's Stable Diffusion (stable-diffusion-512-v2-1). I combine the description of the frame that GPT provides, in addition to the theme and setting that GPT output for the whole storyboard, to generate each frame. Since GPT controls the data sent to Stable Diffusion with the description of the frame as well as the theme and setting, if your prompt dictates a theme it should hopefully translate into a theme in your storyboard. Both the storyboard and the 'prompt enhanced' image generation in the 'Create Content' tab pre-feed a GPT request with a summary of Stability Al's prompt guide. It will try and pick keyword weights to improve the image, and much like the setting and theme, keywords should be influenced by the initial prompt provided to the product. Conclusion: Have fun and make my 2 weeks of work seem worth it! Voting on storyboards and creating storyboards both require a simple Google login to get access. https://meyer.id April 21, 2023 at 05:35AM

Show HN: InsightFlow https://ift.tt/RYAOE8F

Show HN: InsightFlow Hey everyone, sharing InsightFlow, a (long) weekend project I made using GPT4. I am bit anxious sharing it since I barely knew how to code in Python before but I was simply amazed on how much GPT was able to help me write something that actually works (I hope). My goal was to create a library that empowers people to ask questions from their data, regardless of its source. InsightFlow does just that, it has some modules that allow s parsing information existing in (for now) video (its audio part), html, and in general text and provides a chat interface on top. I would love to expand this to image and eventually video parsing. I know there are some companies that aim for the same but I could not find an opensouce alternative for it. I tried making it modular so different modalities can be added later on. https://ift.tt/7l1ypnv April 20, 2023 at 06:22PM

Show HN: GoGoBrowse – A Peer to Peer Web Browser Hi HN! GoGoBrowse is a side project I've been working on that allows 2 users to browse the web together while voice chatting. It's a proof of concept for a new model of browsing the web I've been thinking about. My thought is that before a leap to a 3D Metaverse, we need a 2D Metaverse, which is simply social web browsing. I wrote more about it here: https://ift.tt/rhCfJZP... Though the goal of an entirely social web browser is still quite a ways off, I think of this as a small first step in that direction. I'd love any feedback on the app itself, and the general concept of social web browsing. https://gogobrowse.com April 19, 2023 at 11:50PM

Show HN: A web decision game 99% coded by GPT4. Uses agent to decide win/loss https://ift.tt/w8cgXIE

Show HN: A web decision game 99% coded by GPT4. Uses agent to decide win/loss Yeah... so I know some software development concepts well I haven't written any code in 10 years, so like half the time was just getting a development setup. At first it suggested PyCharm and honestly it wasted a lot of time. Eventually I got VS Code and GPT just seems to understand it so much better. The real secret to getting good responses with GPT-4 during this I found is to restart the conversation fresh with a complete description of what you need (2-3 paragraphs of detail is great) and the rest as code. [detailed description of what you need, make sure it's detailed and specific add examples if possible] #### [insert all the code, the more you can fit the better] That first code block it gives you back on the first output is the cleanest by far. If there is an error and you submit it back in the same chat conversation, it just gets diluted/saturated over time, hallucinations go up etc. So if there is a bug rather than continue in the same convo, repeat this process in a brand new conversation. Each time it gives a much cleaner, fresher look at the code and goals needed. If your codeblock is really small then this isn't so important, but I'm trying to maximize the amount of code per prompt for best responses. I also make sure to split files by concerns so they don't get too big for the prompt window otherwise it's annoying. #### And lastly the other interesting thing about this project is this simulates an Agent loop where it is constantly trying to determine if the player won or lost, decide what the next most cohesive step is based on the human feedback (click emoji) and looping it. Actually that was my main interest for the project and I just wanted to get something published as a secondary goal. Most of my time was probably spent playing with the prompt and trying to to see if I could get it to determine if the goal was achieved but its actually a hard problem and I have some cool ideas for the next project. https://ift.tt/4d6ShFC April 19, 2023 at 11:41AM

Show HN: Database for analyzing US companies, visualize using Apache SuperSet https://ift.tt/AgB26qa

Show HN: Database for analyzing US companies, visualize using Apache SuperSet My main motivation was that I wanted to be able to drill down and filter across all the available stocks, look at the data for myself, and narrow down on the stocks I am interested based on my own sets of criteria, and make data-driven analysis for my personal investment strategies. I used PostgreSQL as the backend database for ELT data pipelines, and used Citus Data cstore_fdw for columnar compression for the final dataset. All financial data is coming from SEC Edgar, https://ift.tt/HzquX17 . I used Python for downloading most of the data. I also run the data load development locally on my home Ubuntu server that I built 5 years ago. I bought 4TB of M2 disks for best database performance, with PRIME B360M-A motherboard and Intel Chip Coffee Lake S. I built the website simply using WordPress, and I run Apache Superset using gunicorn via Apache Webserver reverse proxy. The registration form I had to build myself with PHP and some JavaScript, because it needed to automatically create a SuperSet user upon registration. Otherwise, I would need to input everyone manually. I used Python again for the data integration. Please don't use the database directly as an investment tool, as its in Beta, and the data still needs to undergo heavy data quality checks, please confirm all the numbers yourself, as I provide a link for every company to the SEC filings. https://ift.tt/JmlbAQ4 April 19, 2023 at 02:46AM

Show HN: Let your body be the gamepad Hi HN, I made a keyboard emulator that tracks your body pose and emits the key presses accordingly. My main motivation was to make my kids move more on rainy days. I already made a couple of mini-games using the body pose [1-3], and those were definitely fun to make and play! However, once the kids learned the tricks, they got bored. I could only produce that much content myself, and soon realized that I lack time for churning out games. Finally, I decided to tap into an endless pool of PC games, preferrably simple and less addictive ones like the Gameboy and DOS games. This project has been also inspired by [4], which has been featured on HN recently.

Show HN: TYON, a Simple JSON Alternative https://ift.tt/mr8TNRk

Show HN: TYON, a Simple JSON Alternative TYON (typed object notation) is my attempt to address the main frustrations I have with JSON. 1. Key repetition - you can specify the key names once at the start of a list or map, instead of on each object separately. 2. Escaping strings - everything in a string is literal except for " which is escaped as "". This makes writing regexes and multiline text easier without introducing a bunch of different string styles or excess escaping, which I am not a fan of. 3. While not nearly as important as the first two to me, I did reduce symbol clutter when possible. Files are implicitly maps, keys don't require quotes in most cases, and you don't need commas between items. 4. Decoupling syntax and data formats - TYON has recommended formats for interoperability, but none of these are part of the core spec, so tools are equally welcome to just treat everything as a string. The linked repo contains the spec and a cli app that provides formatting, validation, and conversion to JSON. https://ift.tt/7cYAid2 April 15, 2023 at 03:10AM

Show HN: Don't Hold Your Breath – Breathing Analysis with Polar H10 HR Monitor https://ift.tt/hyZMV5K

Show HN: Don't Hold Your Breath – Breathing Analysis with Polar H10 HR Monitor A person's heart rate fluctuates based on factors such as activity, environment, and mental state. Additionally, heart rate variations occur on a much shorter timescale, with changes happening every few seconds. During inhalation, heart rate slightly increases, and it decreases again during exhalation, a phenomenon known as respiratory sinus arrhythmia. There are several reasons for this. Firstly, an increase in volume within the thoracic cavity (the space between the ribs) leads to a corresponding drop in pressure, which is counteracted by a rise in heart rate to regulate blood pressure. Secondly, breathing is deeply intertwined with the autonomic nervous system, which involves the opposing activation of the parasympathetic ("rest and digest") and sympathetic ("fight or flight") responses. By measuring heart rate variability and regulating our breath, we can gain insight into our stress response and learn to control it. The Polar H10 heart rate monitor provides basic heart rate measurements from a chest strap ECG, compatible with a number of fitness tracking apps that monitor heart rate zones wirelessly using bluetooth. The device also provides raw sensor data including an accurate measure of the timing between heartbeats (interbeat interval, with millisecond resolution) and 200 Hz accelerometer data. In this project this information is used to measure breathing rate and heart rate variability, and explore the relationship between the two. https://ift.tt/lAHErQg April 15, 2023 at 12:36AM

Show HN: NeverPrinter – find and use thousands of nearby printers Hi all, My friends and I have created a Chrome extension and we are looking for feedback on whether people find it useful or not. The extension is intended to serve as a home printer substitute for people (like us) who don't want or need their own printer at home. It makes it easy to send documents to nearby office supply / shipping stores for printing and pickup. Installing the extension adds a printer named NeverPrinter to your list of available printers in Chrome. When you print a document with NeverPrinter, a new tab opens allowing you to select which nearby store you want to send the document to. This is the latest iteration in an ongoing project my friends and I have been working on. We would love to hear any positive or negative feedback. You can get the extension by going to the Chrome Web Store and searching for "NeverPrinter."

Show HN: A minimalist net worth tracker for individuals Hi HN, Today I'm launching the Net Worth Tracker by Flow Finance, a beautiful and minimalist Excel template that allows individuals to track their assets, liabilities, income, and spending on a monthly basis. The focus of this template is understanding long-term trends in the incoming and outgoing expenses for an individual—always with a focus on maximising insights while minimising user inputs. This project was created because the alternatives, frankly, are completely overwhelming. A friend of mine introduced me to the FIRE Movement and, after doing deep dives through Reddit, I tried to find templates to help facilitate a financial tracking system of my own. Every template felt like complete overkill: portfolio tracking for shares, mortgage repayment calculators, even a kind of speedometer which moved depending on my savings rate. Clever, no doubt, but unnecessary for my purposes. After years of tinkering and refining what I truly wanted out of this spreadsheet, I realised it was to clearly understand the flows of my finances. This spreadsheet does not attempt to compete with a typical FIRE spreadsheet or tools like YNAB/Mint, it is about capturing the big picture once a month and essentially taking a snapshot of my financial health. I've priced this spreadsheet at $15 which I believe is a fair price for the value you'll see in taking more control over your personal finances, however as an added incentive (and because I am proud of what I've created and would love more people to use it), I'm currently offering a 50% discount to all HN users, who can use the code f3g27mt at the Gumroad checkout. Thank you for your time and I sincerely hope this product can assist you as much as it has for me. I am more than happy to answer any questions you may have so please feel free to comment below or reach out at contact@getflow.finance. Thank you! https://ift.tt/LFM6QZ3 April 13, 2023 at 04:37AM

Show HN: GPTCache – Redis for LLMs https://ift.tt/oYbKUSa

Show HN: GPTCache – Redis for LLMs Hey folks, As much as we love GPT-4, it's expensive and can be slow at times. That's why we built GPTCache - a semantic cache for autoregressive LMs - atop the vector database Milvus and SQLite. GPTCache provides several benefits: 1) reduced expenses due to minimizing the number of requests and tokens sent to the LLM service 2) enhanced performance by fetching cached query results directly 3) improved scalability and availability by avoiding rate limits, and 4) a flexible development environment that allows developers to verify their application's features without connecting to LLM APIs or network.

Show HN: I’m building an autonomous business run by ChatGPT https://ift.tt/lNzoQ04

Show HN: I’m building an autonomous business run by ChatGPT Hey HN!! I just shipped a project called Airfeed: https://airfeed.co/ Here's how it works: 1. You tell it the research topics you're interested in following This can be anything -- LLMs, chatbots, image generation, scaling model inference, small language models, datasets, etc. 2. Every morning, it filters new AI research papers for quality work that is relevant to your configured topics, and sends you an email summary. Here's a sample email: https://ift.tt/nxPNYaS --- As a fun experiment, I've made everything completely autonomous: Every morning, ChatGPT takes care of filtering/processing all research papers & writing each email. --- Why I built this: I think there needs to be a better way for engineers, researchers, and AI product builders to stay up to date on the latest AI research that's relevant to whatever they're working on. For someone building LLMs, this could mean keeping up with research papers covering multiple topics, ex: scaling attention, model architecture, new datasets, new fine-tuning techniques, etc. --- How this is different from other newsletters: This isn't a generic AI newsletter. It's research-focused & personalized, since it only highlights the papers that might be relevant to you (based on your specific topics). I found this to be useful, since a lot of papers are irrelevant and/or low quality. --- When building maroofy.com [1], I would regularly read the latest research papers on everything related to: contrastive learning, vector embeddings, music classification, etc. So, I thought it would be nice to build something that filters/summarizes just the new research papers covering topics I care about, and sends me the top ones in a daily, morning email. Would love any feedback!! :D [1] https://ift.tt/XIl9g05 https://airfeed.co/ April 13, 2023 at 03:22AM

Show HN: GPT-4-powered web searches for developers https://ift.tt/h2sEkx9

Show HN: GPT-4-powered web searches for developers Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a step-by-step guide complete with citations ( https://ift.tt/Mn2i4hd... ) while Phind in default mode meanders a bit and answers the question very generally ( https://ift.tt/pR2Ccro... ). GPT-4 is significantly more concise and “systematic” in its answers than our default model. It generates step-by-step instructions over 90% of the time, while our default model does not. We’re particularly focused on ML developers, as Phind can answer questions about many recent ML libraries, papers, and technologies that ChatGPT simply cannot. Even with ChatGPT’s alpha browsing mode, Phind answers technical questions faster and in more detail. For example, Phind running on “Expert” GPT-4 mode can concisely and correctly tell you how to run an Alpaca model using llama.cpp: ( https://ift.tt/WN5XjIQ... ). In contrast, ChatGPT-4 hallucinates and writes a make function for a fictional llama.cpp. We still have a long way to go and would love to hear your feedback. https://www.phind.com April 12, 2023 at 11:14PM

Show HN: GPT–LLM native macOS app with time travel, versioning, search https://ift.tt/Ghvck3s

Show HN: GPT–LLM native macOS app with time travel, versioning, search Hey everyone! I made a Mac app for exploring large language models. It’s fast, small, has a tiny memory footprint. It’s immutable by design with both immediate time travel and automatic versioning as foundational elements. The app is written in Swift and a bit of Rust for the tokenizer. I used SwiftUI for structure and animations and Cocoa for advanced behavior. All storage is SQLite and local-only. You can go through the database as needed and backup it as well. The app has support for variants, which is the `n` parameter in the OpenAI chat completion API—equivalent to the drafts feature in Bard. It shows model- and ChatML-aware tokens and cost, and it dynamically adjusts response length in function of prompt length and context length. It supports hiding runs that are not useful, marking the ones that are notable, and going through the ancestry of the current run. It also has support for examples, as specified in ChatML, conversation names and personal and local-only notes. The full-text search works across all stored text and it has support for `all`, `any`, `prefix` and `phrase` matching; the results are time-ordered rather than ranked for the time being. There are several shortcuts and more are coming so that the app can be used entirely by keyboard. You can export to JSON and all data is exported. The app is sandboxed and notarized. The API keys are stored securely in the Keychain. Next I plan to implement combinatorial runs (mixing multiple values of the same parameter and multiple models as well) and full Markdown support. Currently only OpenAI’s conversational models are supported (GPT 3.5, GPT 4 8K, GPT 4 32K), but I’ll be adding support for local models and custom ChatML endpoints as soon as possible. Give it a try. Any and all feedback welcome! Thoughts and questions as well! William https://thellm.app April 11, 2023 at 11:34PM

Show HN: Skip the SSO Tax, access your user data with OSS https://ift.tt/xPW6QA1

Show HN: Skip the SSO Tax, access your user data with OSS As the former CTO of an Insurtech and Fintech startup I always had the “pleasure” to keep regulators and auditors happy. Think of documenting who has access to what, quarterly access reviews, yearly audits and so on… Like many others we couldn’t justify the Enterprise-plan for every SaaS tool to simply get access to SSO and SCIM/SAML APIs. For Notion alone the cost would have nearly doubled to $14 per user per month. That’s insane! Mostly unknown to people, SSO Tax also limits access to APIs that are used for managing user access (SCIM/SAML). This has proven to be an incredibly annoying roadblock that prevented me from doing anything useful with our user data: - You want to download the current list of users and their permissions? Forget about it! - You want to centrally assign user roles and permissions? Good luck with that! - You want to delete user accounts immediately? Yeah right, like that's ever gonna happen! It literally cost me hours to update our access matrix at the end of every quarter for our access reviews and manually assigning user accounts and permissions. I figured, there must be a better way than praying to the SaaS gods to miraculously make the SSO Tax disappear (and open up SCIM/SAML along the way). That’s why I sat down a few weeks ago and started building OpenOwl ( https://ift.tt/S0t9KQF ). It allows me to just plug in my user credentials and automatically download user lists, including permissions from SaaS tools. Granted, OpenOwl is still a work in progress, and it's not perfect. At the moment it's limited to non-SSO login flows and covers only 7 SaaS vendors. My favorite part is that you can configure integrations as “recipes”. The goal was for anybody to be able to add new integrations (IT managers and developers alike). Therefore you ideally don’t even have to write any new code, just tell OpenOwl how the new SaaS vendor works. What do you think? Have you dealt with manually maintaining a list of users and their permissions? Could this approach get us closer to overcoming parts of the SSO Tax? https://ift.tt/S0t9KQF April 11, 2023 at 06:10PM

Show HN: A ChatGPT TUI with custom bots https://ift.tt/vECsMBx

Show HN: A ChatGPT TUI with custom bots Hi HN! We just shipped a full-featured TUI (Text User Interface) for chatting with your Marvin bots, powered by GPT 4 or GPT-3.5. Like all of Marvin, it's fully open-source and we hope you find it useful. To launch it, upgrade and run `marvin chat`. The TUI is built with Textual ( https://ift.tt/Tn8aY96 ) and uses some of its newest features including background workers and modals. We've made base TUIs before but this is the first one that's a true "app" with many screens and coordinated global state. Happy to answer any questions about working with Textual - once it "clicked" it was surprisingly similar to building a traditional front end! Small note: Terminal.app on MacOS isn't great for TUIs, so while it'll work, we suggest an alternative terminal. One of our goals with the TUI was to integrate Marvin's bots into the familiar chat UX. Bots can have distinct personalities, instructions, and use plugins, so each one is like a mini "conversational application." You might know about Marvin because of AI Functions, but at its core Marvin is a library for building and deploying bots (in fact, AI functions are actually a bot!). We started building the TUI as a way to quickly explore and assess our bots' capabilities. It quickly became so useful that we decided to make it a first-class experience. We've preloaded several bots, including one that can guide you through an RPG and another that is obsessed with explaining regex, and will add many more. You can even create your own bots just by asking the default bot (Marvin) to help you. We hope the TUI is a fun way to quickly interact with your bots and it was a great way for us to learn Textual. Please check out the code and let us know what enhancements we can add! https://ift.tt/s8htLq7 April 9, 2023 at 12:40AM

Show HN: The Future of Data APIs https://ift.tt/Ao8mZ2u

Show HN: The Future of Data APIs Hello everyone, I'm Matteo, and, over the last few months, I have been working with my co-founder and other folks from Goldman Sachs, Netflix, Palantir, and DBS Bank to simplify building data APIs. I have personally faced this problem myself multiple times, but, the inspiration to create a company out of it really came from this Netflix article (https://ift.tt/FQyMKfX). You know the story: you have tons of data locked in your data platform and RDBMS and suddenly, a PM asks to integrate this data with your customer-facing app. Obviously, all in real-time. And the pain begins! You have to set up infrastructure to move and process the data in real-time (Kafka, Spark, Flink), provision a solid caching/serving layer, build APIs on top and, only at the end of all this, you can start integrating data with your mobile or web app! As if all this is not enough, because you are now serving data to customers, you have to put in place all the monitoring and recovery tools, just in case something goes wrong. There must be an easier way !!!!! That is what drove us to build Dozer. Dozer is a simple open-source Data APIs backend that allows you to source data in real-time from databases, data warehouses, files, etc., process it using SQL, store all the results in a caching layer, and automatically provide gRPC and REST APIs. Everything with just a bunch of SQL and YAML files. In Dozer everything happens in real-time: we subscribe to CDC sources (i.e. Postgres CDC, Snowflake table streams, etc.), process all events using our Reactive SQL engine, and store the results in the cache. The advantage is that data in the serving layer is always pre-aggregated, and fresh, which helps us to guarantee constant low latency. We are at a very early stage, but Dozer can already be downloaded from our GitHub repo (https://ift.tt/12h9jJD). We have taken the decision to build it entirely in Rust, which gives us the ridiculous performance and the beauty of a self-contained binary. We are now working on several features like cloud deployment, blue/green deployment of caches, data actions (aka real-time triggers in Typescript/Python), a nice UI, and many others. Please try it out and let us know your feedback. We have set up a samples-repository (https://ift.tt/GnXvK0E) for testing it out and a Discord channel (https://ift.tt/02KmfG7) in case you need help or would like to contribute ideas!

Show HN: Daba – Turn your JSON into a database https://ift.tt/k5lb1Ro

Show HN: Daba – Turn your JSON into a database Hi all, I built this tool when I needed a simple LocalStorage-esque database for a client project, and figured others might want something similar. Basically turns your JSON into a query-able, hosted database in seconds. You can read/update/delete JSON files by path, just like you would in Javascript. So, something like get(”users[7].address”) And while we’re at it, I also built a simple file storage service where you upload a file and it gives you the URL back. A lot of my (and other devs friends') side projects will never require more data than a JSON file can handle. Yet we always have to go through the hoops of setting up and using databases meant to handle huge amounts of data. There are many other services that could benefit from the same minimalist philosophy. The idea is to have a bunch of building blocks of different services, and let the developer scale up/down the complexity as they see fit. I'm working on more services for daba (In no particular order: SQLite db?, auth, emails, …) You can use this for any applications where the data can fit in a JSON file. (e.g. Website CMS, blog, portfolio, small mobile apps, internal tools, …). You’ll be surprised at how much data a 20mb JSON file can hold: https://ift.tt/IDtAp3w...

Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby https://ift.tt/r2jLgPS

Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby Hey folks, wanted to show this off and get feedback. Still early/experimental but there are quite a few concepts I'm excited about here. This project came about while writing a program in Go and loving its approach to concurrency. Being a long-time Rubyist I immediately started to think about what similar concepts might look like in Ruby. I set out with two main design constraints: 1. Lightweight: I didn't want routines to be backed by fibers or threads. Having been involved some in the async project ( https://ift.tt/lVvM1N3 ), I had some experience using fibers for concurrency but was curious if they could be avoided. 2. Explicitness: Routine behavior must be written to describe exactly how it is to behave. I always felt like concurrent code was hard to fully understand because of the indirection involved. On the spectrum between tedium and magical I wanted to err more on the side of tedium with Goru. Goru routines are just blocks that are called once for every tick of the reactor. It is up to the developer to implement behavior in terms of a state machine, where on each tick the routine takes some action and then updates the state of the routine for the next tick. This fulfills both design constraints: 1. Because routines are just blocks, they weigh in at about ~345 bytes of memory overhead. 2. Routine behavior is explicit because it is written as a state machine inside the block. Couple more features worth noting: * Goru includes channels for buffered reading/writing (similar to channels in Go). * Goru ships with primitives for non-blocking IO to easily build things like http servers. Curious your thoughts! https://ift.tt/peUMHr2 April 3, 2023 at 07:17PM

Show HN: Shhhbb, an SSH BBS Hello all :) I made this BBS for fun and thought you all would enjoy it. It's not perfect, but it's been a fun exercise! see it: https://ift.tt/zy5w62N try it: ssh -p 2223 shhhbb.com host it: https://ift.tt/hjBrQxb why? Every year I challenge myself in some new way, this year it is to push one project per week. You might recognize my static site generator [0] or my releaser for go [1] from previous posts as one of these weekly projects. If you want to join me in doing this, it's been a blast and I highly recommend it! Maybe we can chat on the bbs about it :) [0] - bearclaw tiny static generator - https://ift.tt/iDdL1cF [1] - release.sh release builder for go - https://ift.tt/iDdL1cF need: I'd love a few co-conspirators, or even some new friends for the bbs software or the bbs itself. A lofty nice-to-have goal is meeting a few other similarly motivated people to conspire with on a weekly basis. If that's you, drop me a line! goals: I have about half of an admin interface endpoint pushed up, which I'd like to finish. I realized mid-commit that I'd lacked some other material in a previous commit, and in pushing it up, I ended up pushing half the admin feature. Stay tuned for that. I'd also like to implement a feature where I surrender the socket to a new process so I can upgrade the binary without dropping all of the connected users. I'm not sure on the feasibility of this, but all the words fit together, so it'll be tried. https://donuts-are-good.github.io/shhhbb/` April 2, 2023 at 10:10PM

Show HN: Integrating puzzle rush and spaced repetitions for chess training https://ift.tt/tPgXLsG

Show HN: Integrating puzzle rush and spaced repetitions for chess training Hi HN! I’m publicly releasing BraiMax Chess, a web app I built during the last three months; it’s based on a training technique which brought me from around 1700/1800 to 2000 rating (superblitz) on lichess. Here it is: https://ift.tt/oKT0ye6 Background story: during lockdown I decided to try and improve at chess, which I was playing online a lot. Bought a few books, tried all the websites and apps I found. This serious study helped a lot in understanding the game better, but didn’t improve my results as much as I hoped. It also was very hard work, and after a few months I stopped having the motivation to continue. Around that time I discovered Puzzle Rush on chess.com; that one was the most enjoyable chess-related thing I could do besides playing games, and it helped with tactics, but I soon plateaued - until I thought about combining that with spaced repetitions. I would manually review the puzzles I had failed, and add them to a rudimentary spaced repetitions system I had hacked together. It was a bit of work, but still enjoyable enough to stick to it; that’s when I started getting noticeably better and better, making fewer blunders, and climbing the rating. Late last year I decided to take some time off after leaving my last job; during the break I felt an itch and decided to create a website which would allow anybody to use the same technique I described above, but in a much easier/integrated way. After three months of full time work on it, it’s ready! Let me know what you think Dan https://ift.tt/YatgjO6 April 2, 2023 at 03:06PM

Show HN: Build your own no-code editor with Reka.js https://ift.tt/Ne2R7Sv

Show HN: Build your own no-code editor with Reka.js Much of the complexity surrounding building no-code editors come from architecting the state management system to power such editors: how can we allow end-users to create and edit entire UI components directly from the browser? Reka solves this by providing an AST-powered state system that enables end-users to create UI components that are nearly as complex as ones that developers could write in code; along with an interpreter to efficiently compute an output that could be rendered on the browser. Furthermore, Reka provides additional extensions, such as enabling real-time collaboration via CRDTs; or you could build a custom extension to support additional functionalities such as a commenting system. All that's left is for you to build your own UI abstractions on top of Reka — designing your editor UI/UX and providing easy-to-use buttons/controls for your end-users to mutate the underlying state in Reka.

Show HN: AI Shakespeare https://ift.tt/hEtVliJ

Show HN: AI Shakespeare These days thinking of ways to uniquely show off a text to speech model is tough, as there are a lot of them out there. We thought it would be fun for April 1 to show something a bit on the silly end of things -- we trained our TTS model on "Shakespearean" theatrical voices, and used GPT to generate short plays which are then "acted" out. This lets us show the versatility of our model, that we use in more "serious" settings for generating branded voices for particular languages or accents. It should be noted, the dataset is of our own curation; all voice actors were compensated with full knowledge of being used for TTS and were thrilled to be part of a creative project like this. We resample the speaker embedding space to find voices that are different from any one particular actor. https://ift.tt/CL9KGHx April 1, 2023 at 02:00PM

Show HN: Coursemate, connect with other self learners https://ift.tt/2VU6LDo

Show HN: Coursemate, connect with other self learners Hey Hacker News! My name is Collin, 18 years old and doing a gap year after finishing high school last year. This was my first real project after starting to learn web development around 5 months ago. I came up with this idea as it was a real pain for me to find other people from my country and especially my age, learning and taking online courses about the same stuff online. Lots of these online courses include their own discord communities and forums, but I still found it very hard to connect with other people in there. Thats why I built Coursemate. I would love to get your feedback on it! :) https://ift.tt/FedoA9J April 1, 2023 at 02:08PM
