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? And are there any notable pain-points of using a hosted monitoring product? (We're toying with the idea of an enterprise deployment). Excited to hear from everyone.

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

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.

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 https://ift.tt/J9XkiZD

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." Or you can visit https://ift.tt/4heqwc1 , which will redirect you there. https://ift.tt/0xg7UhP April 13, 2023 at 11:18PM

Show HN: A minimalist net worth tracker for individuals https://ift.tt/9RGdiE6

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!

I’d love to get some feedback on ways to make the app better, and any other ideas on how to make learning more fun and engaging. https://ift.tt/dIOqrhM April 6, 2023 at 05:27PM

Show HN: I feed all my daily entries to an AI (ChatGPT) Hello there! I hope you're doing well today! I wanted to share something with you. Recently I was on the hunt for the best way to journal daily. Well, I had this idea - what if I could feed all my daily entries to an AI (ChatGPT), and create a friendly, supportive character like Socrates or Simon Sinek? This way, I could ask any questions about my life and mental health, and get some amazing advice on how to improve myself! The results have been absolutely mind-blowing ! I even made a short GIF to show you how it works - check it out! - https://ift.tt/zRklmb1 I've shared this with my friends, and they loved it so much that they've been asking me to create a full-featured journalling app with an AI assistant! What do you think? Would you be interested in using an app like this? I'd love to hear your feedback and thoughts on this. Please feel free to drop a comment and let me know what you think! Right now, I'm just collecting a waitlist of people who are interested in the app, so if you're interested, here is a link for signup to waitlist - https://ift.tt/1IXdiOM .If I can get 100 people on the waitlist in the next few days, I'll launch the app!

Show HN: GPT-4 powered brand name generator As a fun weekend project to take a break from the everyday work-university cycle, I've messed around with OpenAI's GPT-4 API and created a simple name generator with it. In the coming days, I'll be adding more features. https://www.namique.xyz/ April 5, 2023 at 04:49AM

Show HN: Live coaching app for remote SWE interviews, uses Whisper and GPT-4 https://ift.tt/UNuZJxt

Show HN: Live coaching app for remote SWE interviews, uses Whisper and GPT-4 Posting from a throwaway account to maintain privacy. This project is a salvo against leetcode-style interviews that require candidates to study useless topics and confidently write code in front of a live audience, in order to get a job where none of that stuff matters. Cheetah is an AI-powered macOS app designed to assist users during remote software engineering interviews by providing real-time, discreet coaching and integration with CoderPad. It uses Whisper for audio transcription and GPT-4 to generate hints/answers. The UI is intentionally minimal to allow for discreet use during a video call. It was fun dipping into the world of LLMs, prompt chaining, etc. I didn't find a Swift wrapper for whisper.cpp, so in the repo there's also a barebones Swift framework that wraps whisper.cpp and is designed for real-time transcription on M1/M2. I'll be around if anyone has questions or comments! https://ift.tt/wyC09Af April 5, 2023 at 05:06AM
