Show HN: Epidemik a Python package for epidemic simulation https://ift.tt/vy9Y7S3

Show HN: Epidemik a Python package for epidemic simulation Hi everyone, I'm happy to share `epidemik`, a Python package for epidemic modeling. Epidemik, currently supports: - Homogeneously mixed Model: Easily define compartmental models by just specifying the transitions and rates - Age Structure: Convert any compartmental model to an age-structured model by simply adding an age contact matrix and a the population of each age group - Network Model: Easily define epidemic models running over an arbitrary network structure - Meta-Population Models: Define metapopulation model In a previous life (circa 2008-2012), I worked as the leading developer for a large-scale epidemic model so when CoVID hit I wrote a series of blog posts (see https://ift.tt/6WPcuD9 ) working through the mechanics of how this kind of model works. Epidemik is the result of all the code that got written during the lockdowns, and in the years since that, I finally cleaned up and decided to publish it in case others find it useful (perhaps as a teaching tool?) This is my first package, so feedback, comments and suggestions are definitely welcome. https://ift.tt/3bCspov June 12, 2024 at 12:41AM

Show HN: A keyboard-centric clipboard history app for macOS https://ift.tt/75BvuF6

Show HN: A keyboard-centric clipboard history app for macOS Hey HN, As a Software Engineer, I frequently copy and paste content. The fact that macOS clipboard buffer can keep only one item is very frustrating. It’s very annoying to copy → switch app → paste → switch app → copy → switch app → paste, and so on. Losing items I copied hours ago and having to find and copy them again is a waste of time. I tried many third-party clipboard managers like Alfred, Raycast, Paste, Maccy, etc. While great, they didn't fully meet my needs. As a developer, my requirements are: 1. Keyboard-centric operation to avoid using the mouse. I don’t want to waste my time moving my hands from the keyboard. 2. Display many clipboard history items at once. I don’t like the idea with big tiles, so I can see only 5-7 history items on my 32” monitor. 3. Full content preview for each clipboard item. 4. Quick search functionality. So, I created ClipBook for my own use. After months of development, daily use, and positive feedback from my colleagues, I decided to share it publicly. It’s free. All data is securely stored on your computer. I’m planning to make it open source as well. If you try it out, please let me know if you found it useful, if you have anything you’d like me to add, or if you have any other feedback. Happy to answer any questions. Much appreciated. https://clipbook.app/ June 11, 2024 at 10:10PM

Show HN: I Build an AI-Powered API That Instantly Obtains Website Information I built SiteProfile(siteprofile.io) to simplify how we access detailed website information. The main feature of SiteProfile is that you can obtain all relevant website information with a single, simple API call. With one API call, you can immediately get the following information: 1.Real-time Webpage Screenshots Instantly capture real-time screenshots in both PC or Mobile views. 2. AI-Generated Content: Generate content based on user prompts and website data, e.g. Describe the core functions of this website. 3.Comprehensive Website Info: Social Media Links, Contact Info, Basic Details, and Assets, all in one place. With just this API, you can instantly create an ai directory or similar website. SiteProfile is currently in the testing phase. During this period, all subscriptions are discounted. There are still a few minor issues, and I’m working hard to fix them. If you try it out, please let me know if you found it useful, if you have anything you’d like me to add, or if you have any other feedback. And if you have any questions, I’d be happy to answer.

Show HN: I wrote a partial re-implementation of DirectMusic https://ift.tt/hZSe8i9

Show HN: I wrote a partial re-implementation of DirectMusic DirectMusic[1] is a deprecated Windows API for playing dynamic music scores authored using DirectMusic Producer[2]. It was originally released as part of DirectX in 1999 and discontinued with the release in Windows Vista around 2009-ish. Due to my involvement with projects[3] re-implementing an old game engine for the early 2000's games Gothic and Gothic II[4], I came to notice that existing solutions[5] were incorrect and hard to use. Thus, I was tasked with writing a new, correct re-implementation of the API. Today, my re-implementation is able to (mostly) play back so-called style-based segments[6] and is fully tested against both the Gothic and Gothic II soundtracks. I am actively working on getting the Lego Island 2 soundtrack working as well. There are many features of DirectMusic which the library does not currently support, simply because I have not been able to find or test soundtracks using them, so if you want to contribute, I'd love to know about software shipping with DirectMusic soundtracks!

Show HN: I built job search platform for Architects Hi HN, I started my solopreneur journey this year and I’d like to share something I’ve been working on: ArchGee - a job search platform for architects, interior designers, urban planners, and other professionals in the architecture field. Coming from an IT background, I’ve seen plenty of job boards for IT roles. However, my architect friends often struggle to find job opportunities specific to their unique skills. Archgee is designed to fill this gap. It’s tailored exclusively for the architecture community, making it easier to find relevant opportunities. At first I am planning to integrate jobs from other search platforms (jobs that are relevant to architecture), then partnering with industry companies to ensure high-quality job posts and aim to create a supportive space for networking and growth. I’m here to seek your thoughts and feedback. Mirza June 9, 2024 at 12:40AM

Show HN: Air Orbe: Exploring the Future of Smart Device Control [video] https://ift.tt/I8EDwZc

Show HN: Air Orbe: Exploring the Future of Smart Device Control [video] When it comes to smart devices, one of the most challenging tasks I faced was labeling the lighting zones in my home. No matter how hard I tried to make sense of it, the process was always cumbersome and didn't seem intuitive to everyone. I often thought about a future where controlling the lights could be as simple as looking at them. This vision fueled my desire to create a more cohesive and user-friendly experience. The breakthrough came when Apple launched the Vision Pro. I knew immediately that this technology could finally enable the solution I had been dreaming of. By leveraging the capabilities of Vision Pro, especially PERSISTENT WORLD ANCHORING, we could build a system where users control their lights and other smart devices simply by looking at them. This innovation would make smart device control more intuitive than ever. https://www.youtube.com/watch?v=aOHZzFxhy5o June 8, 2024 at 01:51AM

Show HN: I built a tool to A/B test promotions to maximize conversions Hey HN, I've just begun my solopreneur journey. I've been a "serial starter" - often starting projects and never seeing them through, and I have finally finished my first project! Maybe this sentiment resonants with some of you, let me know in the comments below I built this tool as a simple no-risk method for turning more visitors into customers by A/B testing your sale promotions and automatically displaying the promotion with the highest conversion rate. Did you know that increasing your conversion rate by just half a percent can have a dramatic impact on your sales without needing to increase your traffic? Consider the following example for a $20 product on your website: To earn $1M in sales with a 2.5% conversion rate you would need: 2M visitors. To earn $1M in sales with a 3.0% conversion rate you would need: 1.66M visitors. What do you think is an easier way to get to $1M in sales: Attracting ~ 400K new visitors? Or raising your conversion rate by 0.5%? I hope some of you find this product useful, I would love your feedback! - Xylo https://ift.tt/1nrtkK5 June 6, 2024 at 12:15AM

This allows you to scale up your workers without just scaling up the build time on each test run. Brisk can be run from your local dev environment (the command line or VS Code) allowing your to access the speed of many servers from your local machine or it can be run as part of a traditional CI/CD pipeline (in Github actions etc). I've been working on Brisk for the last few years and I've decided to open source the project.

Show HN: A New Kind of Chat Room https://ift.tt/gdGrAjt

Show HN: A New Kind of Chat Room I’ve developed an application that reimagines chat rooms by integrating them with a world map. Each user can claim a rectangular piece of land on the map, referred to as a "banner." Users within close proximity are grouped into a chat room by the app. The banner’s size can expand or shrink based on the density of users in the area and the number of coins in the user’s account. Key Features: Real-World Interaction Model: Users are pseudo-anonymous, akin to real-world interactions. Coin balance determines user size and visibility ("stature"), while endorsements and other activities form a unique endorsement chart, serving as a digital representation. This allows for interaction without revealing one’s entire social or professional network. Community Clusters: Users can form open communities based on real-world locations. New users can discover and join these clusters via heatmaps, without needing specific URLs or hashtags. Initial Coins: New users start with 1000 coins. These coins can be used to endorse other users' content, earning stakes in the endorsed banner. When others endorse that banner, the original endorser gains more coins. This endorsement economy is experimental, and could eventually involve crypto tokens. Useful Points: Banner Interactions: Clicking on a banner opens it fully. A button with a chart icon on the top right flips the banner to display the activity chart. Compatibility: The application currently works best on Google Chrome. Heatmap View: Zooming out on the map reveals a heatmap of banners. Side Panel Tabs: First Tab: Displays a feed of content from the visible map area. Second Tab: Contains the cluster chat. Current User Base: At the moment, only my friends and family are using the application, so banners are predominantly found in the Chicago area. For more details, refer to the white paper provided. I’m excited to share this application and look forward to your feedback! https://beescribe.com/ May 28, 2024 at 09:37AM

Show HN: Get paid to do your own ML research https://ift.tt/NlefTRB

Show HN: Get paid to do your own ML research I'm launching an experimental research grant that I call Cat's grant (I'll find a better name later). tldr: - you get paid to do your own research and report to me - you keep IP/ownership rights - 10 months duration - choose a grant size of $10k, $50k or $100k total (paid in monthly chunks) - Apply by sending an email to not_a_cat@fastmail.com How it works: You specify the grant size when applying: 10k, 50k and 100k. This total amount will be distributed over a period of 10 months. I will review each application within 1 week. The deadline to apply is June 9. The start date is flexible and can be the start of June, July, August or September. The total budget I will allocate to this is around 100-200k I haven't yet made a proper contract reviewed by lawyers. If interest is strong enough, I will do it and try hard to keep the spirit of what is said here. The contract will be under Swiss law. Rationale: I get to meet cool people, promote and follow cool research. You get to do the research you want with little red tape (I'll be the sole decision maker for applications. Paperwork will be done with the help of other people). Application process: You choose the grant size you apply for. You can apply to multiple ones at the same time. Then, you may be accepted for one grant option or rejected for all. The process has 3 stages: - Email application - First screening call - Second call with more in-depth questions If you complete the 3 steps, you are accepted in the grant program. Reporting requirements: You are expected to produce the following: - A weekly email report that can be as short as a single sentence (meant as a pulse that you are still here) - A monthly research update that has to be public, in the format you want (github file, blog post…) - Do a monthly call with me, discussing the monthly research update Payment schedule: One payment of 10% of the total amount will be made at the end of each month while the grant is active. The grant may be canceled if the reporting and effort is insufficient. The bar for this will be reasonably low. Effort and time spent will be considered good enough for keeping the Grant active.

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm https://ift.tt/M5bADy1

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm After reading about the generation of blue noise here on HN a few times my goal was to implement my own variant of the the Cluster and Void algorithm in the most straight-foward way possible, while also visualizing each step. (JavaScript is required in order to step through the algorithm) Most other Blue Noise generator implementations are optimized for speed. Many explanations of the Cluster and Void algorithm I found online were overly complicated or focusing on details that do no help the initial understanding. My implementation is optimized for readability and understanding. I find it very inspiring see an algorithm broken down to its most essential steps. For one in order to better understand the algorithm itself but also for transfering its key concepts to other tasks, for example when designing my own algorithms. Eg in my rather high level python/numpy implementation one can easily understand that the two phases of the algorithm (phase 2 and phase 3) have no data dependency between each other and can therefor be parallelized. Additionally the numpy implementation demonstrates how the application of high level concepts like rank-polymorphism and convolution allow to express a sophisticated algorithm in only a few lines of code. Hope you like it. https://ift.tt/59aoDQZ May 28, 2024 at 03:37AM

Show HN: Meal planning – without the mental load https://ift.tt/dB1VinL

Show HN: Meal planning – without the mental load TLDR; I applied the concept of "don't make me think" to the task of selecting meals, and assembling the shopping list for your grocery run. The basic idea for what I wanted is very simple: Rather than making a shopping list, I wanted to create a re-usable 'meal', with a list of ingredients I'd need to add to my shopping list to make that meal. Then, after selecting meals for the week I'd have a quick 'check' step, where I'm prompted to check the cupboard for each ingredient, before it's added to the shopping list (ie: I'll need ground beef to make tacos, but I already HAVE ground beef in the freezer). I originally built this out just for myself, but the result has been such a helpful and stress-free experience that I thought others might appreciate it as well. I think this tool could be well-suited for younger folks that are new to the labour of meal-planning. College students, newlyweds, and families with young children. You can try it out without needing to register or provide any personal information, and I'd love your feedback! https://supperstock.ca/ May 28, 2024 at 12:34AM

Show HN: I generated API documentation for all Java packages https://ift.tt/SltEqbB

Show HN: I generated API documentation for all Java packages Hi HN! I'm excited to share a project I've been working on for the past year: Docland. It is an API documentation browser that generates documentation on demand (through compilation, not LLMs) for Java packages. Instead of relying on Javadoc, the built-in doc generator, I created the engine from scratch to give the documentations a modern look, build fast search indexes, and enable link resolution to other packages. I built Docland because I constantly found it frustrating to locate and view API definitions when programming. You'd have to Google the function/class name, skip all the SEO articles, find the page you want, yet the documentation might be poorly formatted or does not support searching. So I thought it would be really cool to create a documentation site dedicated for programming languages and libraries, so that you can find the docs all in one place with a uniform look. Docland currently only supports Java, but more programming languages can be supported thanks to its modular architecture. Please try it out and let me know what you think! Also, the process of building Docland was extremely fun and challenging. I'm happy to share about that too. Thank you! Martin https://docland.io May 26, 2024 at 06:05PM

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go https://ift.tt/EhgLWCd

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go Hi HN, I’m excited to share Spot, a simple, cross-platform, React-like GUI library for Go. It is just a few days old and has lots of missing features but I'm happy with the results so far, and looking for some design feedback. Spot is designed to be easy to use and provide a consistent API across different platforms (mainly Mac & Linux). It’s inspired by React, but written in Go, aiming to combine the best of both worlds: the easy tooling & performance of Go with a modern, reactive approach to UI development. Key features: - Cross-platform: Leveraging FLTK[1] & Cocoa[2], Spot works on Mac, Linux, and the BSDs with plans for native Windows support in the future. - Reactive UI: Adopts a React-like model for building UIs, making it intuitive for those familiar with reactive frameworks. - Traditional, native widget set: Utilizes native widgets where available to provide a more traditional look and feel. Why I built it: I was searching for a cross-platform GUI toolkit for Go that had a more traditional appearance, and none of the existing options quite met my needs. I then started playing with Gocoa and go-fltk and suddenly I worked on an experiment to see how challenging it would be to build something like React in Go, and it kinda evolved into Spot. ¯\_(ツ)_/¯ In 2024, is there a still place for classic desktop GUIs—even with a modern spin? I’d love to hear your thoughts, feedback, and any suggestions for improvement. Also, contributions are very welcome. Thank you for checking it out!

Show HN: Excel to Python Compiler https://ift.tt/x7VTybj

Show HN: Excel to Python Compiler We (me and @aarondia) built a tool to help you turn psuedo-software Excel files into real-software Python. Ideally, Pyoneer helps you automate your manual Excel processes. You can try it today here: https://pyoneer.ai . How it works: 1. You upload an Excel file 2. We statically parse the Excel file and build a dependency graph of all the cells, tables, formulas, and pivots. 3. We do a graph traversal, and translate nodes as we hit them. We use OpenAI APIs to translate formulas. There’s a bunch of extra work here — because even with the best prompt engineering a fella like me can do, OpenAI sucks at translating formulas (primarily because it doesn’t know what datatypes its dealing with). We augment this translation with a mapping from ranges to variable names and types, which in our experience can improve the percentage of correctly translatable formulas by about 5x. 4. We generate test cases for our translations as well, to make sure the Python process matches your Excel process. 5. We give you back a Jupyter notebook that contains the code we generated. If there are pieces of the Excel we can’t translate successfully (complex formulas, or pivot tables currently), then we leave them as a TODO in the code. This makes it easy for you to hop in and continue finishing the script. Who is this for: Developers who know Python, primarily! Pyoneer might be useful if: 1. You’ve got an Excel file you’re looking to move to Python (usually for speed, size, or maintenance reasons). 2. There’s enough logic contained in the notebook that it’s going to be a hassle for you to just rewrite it from scratch. 3. Or you don’t know the logic that is in the Excel workbook well since you didn’t write it in the first place :) Post translation, even if Pyoneer doesn't nail it perfectly or translate all the formulas, you'll be able to pop into the notebook and continue cleaning up the TODOs / finish writing the formulas. What the Alpha launch supports: Launched early! Currently we’re focused on supporting: 1. Any number of sheets, with any reference structure between them. 2. Cells that translate as variables directly. We’ll translate the formulas to Python code that has the same result, or else we’ll generate a TODO letting you know we failed translating this cell. 3. Tables that translate as Pandas dataframes. We support at most one table per sheet, at the tables must be contigious. If the formulas in a column are consistent, then we will try and translate this as a single pandas statement. We do not support: pivot tables or complex formulas. When we fail to translate these, we generate TODO statements. We also don’t support graphs or macros - and you won’t see these reflected in the output at all currently. Why we built this: We did YCS20 and built an open source tool called Mito( https://trymito.io ). It’s been a good journey since then - we’ve scaled revenue and to over 2k Github stars ( https://ift.tt/SpaRAyW ). But fundamentally, Mito is a tool that’s useful for Excel users who wanted to start writing Python code more effectively. We wanted to take another stab at the Excel -> Python pain point that was more developer focused - that helped developers that have to translate Excel files into Python do this much more quickly. Hence, Pyoneer! I’ll be in the comments today if you’ve got feedback, criticism, questions, or comments. https://ift.tt/gyIrhXO May 23, 2024 at 11:10PM

Show HN: We open sourced our entire text-to-SQL product https://ift.tt/2fhNE31

Show HN: We open sourced our entire text-to-SQL product Long story short: We (Dataherald) just open-sourced our entire codebase, including the core engine, the clients that interact with it and the backend application layer for authentication and RBAC. You can now use the full solution to build text-to-SQL into your product. The Problem: modern LLMs write syntactically correct SQL, but they struggle with real-world relational data. This is because real world data and schema is messy, natural language can often be ambiguous and LLMs are not trained on your specific dataset. Solution: The core NL-to-SQL engine in Dataherald is an LLM based agent which uses Chain of Thought (CoT) reasoning and a number of different tools to generate high accuracy SQL from a given user prompt. The engine achieves this by: - Collecting context at configuration from the database and sources such as data dictionaries and unstructured documents which are stored in a data store or a vector DB and injected if relevant - Allowing users to upload sample NL <> SQL pairs (golden SQL) which can be used in few shot prompting or to fine-tune an NL-to-SQL LLM for that specific dataset - Executing the SQL against the DB to get a few sample rows and recover from errors - Using an evaluator to assign a confidence score to the generated SQL The repo includes four services https://ift.tt/UBjKZG4 : 1- Engine: The core service which includes the LLM agent, vector stores and DB connectors. 2- Admin Console: a NextJS front-end for configuring the engine and observability. 3- Enterprise Backend: Wraps the core engine, adding authentication, caching, and APIs for the frontend. 4- Slackbot: Integrate Dataherald directly into your Slack workflow for on-the-fly data exploration. Would love to hear from the community on building natural language interfaces to relational data. Anyone live in production without a human in the loop? Thoughts on how to improve performance without spending weeks on model training? https://ift.tt/2R6fYtG May 23, 2024 at 09:20PM

Show HN: Route your prompts to the best LLM https://ift.tt/l26p35t

Show HN: Route your prompts to the best LLM Hey HN, we've just finished building a dynamic router for LLMs, which takes each prompt and sends it to the most appropriate model and provider. We'd love to know what you think! Here is a quick(ish) screen-recroding explaining how it works: https://youtu.be/ZpY6SIkBosE Best results when training a custom router on your own prompt data: https://youtu.be/9JYqNbIEac0 The router balances user preferences for quality, speed and cost. The end result is higher quality and faster LLM responses at lower cost. The quality for each candidate LLM is predicted ahead of time using a neural scoring function, which is a BERT-like architecture conditioned on the prompt and a latent representation of the LLM being scored. The different LLMs are queried across the batch dimension, with the neural scoring architecture taking a single latent representation of the LLM as input per forward pass. This makes the scoring function very modular to query for different LLM combinations. It is trained in a supervised manner on several open LLM datasets, using GPT4 as a judge. The cost and speed data is taken from our live benchmarks, updated every few hours across all continents. The final "loss function" is a linear combination of quality, cost, inter-token-latency and time-to-first-token, with the user effectively scaling the weighting factors of this linear combination. Smaller LLMs are often good enough for simple prompts, but knowing exactly how and when they might break is difficult. Simple perturbations of the phrasing can cause smaller LLMs to fail catastrophically, making them hard to rely on. For example, Gemma-7B converts numbers to strings and returns the "largest" string when asking for the "largest" number in a set, but works fine when asking for the "highest" or "maximum". The router is able to learn these quirky distributions, and ensure that the smaller, cheaper and faster LLMs are only used when there is high confidence that they will get the answer correct. Pricing-wise, we charge the same rates as the backend providers we route to, without taking any margins. We also give $50 in free credits to all new signups. The router can be used off-the-shelf, or it can be trained directly on your own data for improved performance. What do people think? Could this be useful? Feedback of all kinds is welcome! https://ift.tt/c07Iov8 May 22, 2024 at 08:37PM

Show HN: B-field, a novel probabilistic key-value data structure (`rust-bfield`) `rust-bfield` is a Rust implementation of our novel "B-field" data structure, which functions like a Bloom filter for key-value lookups instead of set membership queries. The B-field allows you to compactly store data using only a few bytes per key-value pair. We've successfully utilized it in genomics to associate billions of "k-mers" with taxonomic identifiers while maintaining an efficient memory footprint. But the data structure is also useful beyond computational biology, particularly where you have large unique key domains and constrained value ranges. Available under an Apache 2 license.

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database https://ift.tt/bDHr6M5

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database Recently I open-sourced SQLFrame, a DataFrame library that implements the PySpark DataFrame API but removes Spark as a dependency. It does this by generating the corresponding SQL for the DataFrame operations using SQLGlot. Since the output is SQL this also means that the PySpark DataFrame API can now be used directly against other databases without the Spark middleman. I built this because of two common problems I have faced in my career: 1. I prefer to write complex pipelines in PySpark but they can be hard to read for SQL-proficient co-workers. Therefore I find myself in a tradeoff between maintainability and accessibility. 2. I really enjoy using the PySpark DataFrame API but not every project requires Spark and therefore I'm not able to use the DataFrame library I am most proficient in. The library currently focuses on transformation pipelines (reading from and writing to tables) and data analysis as key use cases. It does offer some ability to read from files directly but they must be small although this can be improved over time if there is demand for it. SQLFrame currently supports BigQuery, DuckDB, and Postgres with Clickhouse, Redshift, Snowflake, Spark, and Trino in development or planned. You can use the "Standalone" session to test running against any engine supported by SQLGlot but there could be issues with more advanced functions that will be resolved once officially supported by SQLFrame.

Show HN: Drivr – VR with real vehicles [video] https://ift.tt/sKc1pza

Show HN: Drivr – VR with real vehicles [video] This project combines VR with a real vehicle that you are controlling (or is controlling itself, in some scenarios). One advantage this has over traditional VR motion experiences is that your senses all agree with each other, thus greatly reducing the likelihood of motion sickness. The go-kart seen in this video is drive-by-wire and steer-by-wire, so the system will not let the player exit the defined safe area. If a player goes off course, the vehicle will take control, and return them to the start. The autonomous capabilities also allow for games where the player can focus on other objectives other than driving, such as target shooting. No infrastructure is required other than the vehicle and an open place to drive (which honestly has been the most challenging part lately). If you're interested in this project, I'd love to connect! https://www.youtube.com/watch?v=Q76X0cnSGHk May 17, 2024 at 12:49AM

I use Todoist and Notion to manage my work, for instance, but every time I'm out and about and think of a task I need to capture, the mobile apps feel too complex. Or I might think of a feature to add to a product, but don't want to deal with Linear's mobile web view. So, I built Defer: a simple iOS "capture" app that syncs to your menu bar on your Mac. No signup needed, it all "just works" with your Apple ID. Intentionally simple and lightweight. https://deferapp.com/ May 14, 2024 at 12:08AM

Show HN: Git Searcher, search commits for an added or removed string https://ift.tt/ZuegHOE

Show HN: Git Searcher, search commits for an added or removed string Hello all, I created a command line utility called Git Searcher that can find in which commit any line of code was added; it can also find where a line of code was removed. I have found this very helpful for determining where code originated from and for debugging. I hope you find this useful! Many thanks, Sam https://ift.tt/Xe6ZRav May 12, 2024 at 11:20PM

Show HN: Insteadofvery.com As non-native English speakers, we're often advised to avoid overusing intensifiers like "very". This is a simple app to find synonyms of "very x" phrases that are not always possible to find using a standard thesaurus. Built it using OpenAI, FastAPI, and MongoDB (to cache the results). https://ift.tt/NQr4CoV May 12, 2024 at 11:25PM

Show HN: MinimalChat – A Simple and Customizable LLM Chat Application https://ift.tt/hts5nXD

Show HN: MinimalChat – A Simple and Customizable LLM Chat Application Hello everyone! I have a hobby project that has become fairly full featured that I figured I would share. The idea of MinimalChat has been to create a project that is a lightweight and dead simple application that can be deployed locally in a few seconds (with docker). While of course also having most of the nice to have features and looking pretty nice. A nice bonus is it a Progressive Web Application so it can be installed like a normal application to your mobile device. It has a full mobile UI. For those using Chrome and Edge you can also locally download, load and host entirely via your browser models like LLama-3-8b with hardware acceleration via WebGPU. It's pretty experimental but it does work! I won't bloat this post reiterating it's features, the GitHub Readme gives a good idea of the application abilities. I know chat applications are a dime a dozen but...here's another one hah! https://ift.tt/WRqPbJ0 May 11, 2024 at 09:19AM
