Show HN: I build a Python library for zaprite for Bitcoin payment processing https://bit.ly/3Wuvel7

Show HN: I build a Python library for zaprite for Bitcoin payment processing Hey HN! I am Jogi, a solo dev, and I made my first ever FOSS library because I needed to plug into bitcoin payments for a client project and I thought it might help others more easily do the same. My main motivation was to lower the barrier for developers who want to integrate Bitcoin payments into their flask or django projects. I'm not entirely sure if it's any good, which is why I wanted to share it here. Roast it, I can take it lol Anyway, I rarely get feedback on my work from devs, so I'm really looking forward to hearing your thoughts, critiques, and suggestions. If you have experience with Bitcoin integration or library development, I'd especially appreciate your insights. Thanks for checking it out! https://bit.ly/3WlASpu August 1, 2024 at 04:27AM

Show HN: Merlin – Contextual Intelligence Agent for GTM https://bit.ly/3LHNtP0

Show HN: Merlin – Contextual Intelligence Agent for GTM Hi HN! We are building [Merlin]( https://bit.ly/3yfJI0f ), a GTM intelligence platform that gathers contextual insights about prospects and key stakeholders, so sellers don’t have to spend hours on tedious research tasks across hundreds of companies. Our thesis is that content generation and workflow/sequence automation providers are generating a lot of noise in social media (and inboxes) today and they are making the problem of outbound sales worse. We believe that every customer interaction (emails, cold calls or discovery calls) should be powered by intelligence. With the relevant insights, the user can make an informed decision whether to contact the prospect, understand what the prospect is interested in and what are their pain points that the user can solve. We’ve built two main features: Lite Intel - allows you to ask any number of questions across 100s companies. Please feel free to try out this feature for free - https://bit.ly/3WJ1zGc... Deep Intel - provides contextual insights about prospects and key buyers, by automatically understanding the user’s solution and service. This includes identifying new qualified leads based on contextual intelligence, instead of filtering based on # of employees, sectors and technology used. There are several use cases you can apply with our contextual insights: 1. Qualify leads 2. Identify new highly qualified accounts 3. Draft hyper targeted emails 4. Prepare for discovery and follow-up calls 5. We’d love to hear suggestions of other use cases. Could be non-GTM related too We believe the future is in Insights-Led Growth . We’re still pretty early in the development and want to keep on improving on our contextual insights. Any feedback is much appreciated! Thank you in advance! https://bit.ly/3yfJI0f July 30, 2024 at 10:17AM

Posting this again because honestly, I am kinda puzzled about what to add/fix/change due to having 0 users and no genuine feedback. By genuine feedback, I mean feedback from strangers who do not have a social pressure to be polite and pull punches. Please take a look if you find this interesting and leave a comment.

Show HN: How I wrote a LaTeX paper without writing any LaTeX Stempad is an online scientific text-editor. I built it because I wanted a way to do fast scientific writing with just my keyboard, and LaTeX wasn't cutting it. I recently launched the ability to export Stempad documents to LaTex. I tested it by rewriting part of a paper I found online (Metabolic scaling in small life forms by Marc E. Ritchie & Christopher P. Kempes) and exporting it. You can try the editor and export yourself using the post url. The export button is on the top right of the page. In case you want to see the result directly, this was it: https://bit.ly/3LI6GjD Feedback is really appreciated!

Show HN: ClifferBasic, a simple BASIC interpreter as a .NET REPL Ever since I got my first computer, a TI-99/4A, at age 13, I've been fascinated by programming languages. I've written a few interpreters, but this is the first time I've come back to the first language I've ever learned, BASIC. I started ClifferBasic as a way to shake out bugs and find feature weaknesses in another project I'm working on, Cliffer, which is a library for writing CLI applications in .NET using attributed program, but it's taken on a life of its own and has become a rather fun project. I'm planning to flesh out the BASIC implementation over the coming weeks, but I'd like some input from the community to see where I could take it next. Thanks for your time! https://bit.ly/3WC5TH7 July 26, 2024 at 04:04AM

Show HN: Compile Erlang to WASM and run as HTTP/incoming-handler Hello! This is the most useless thing I did in quite some time, but it was fun. Compile erlang (actually BEAM) to wasm, statically link with a small http wrapper and run as a request handler under wasmtime. This is not very practical as of now and you better just compile atomvm and statically link it with erlang payload if you really need to run erlang on the edge node (you don't). When (if) typed continuations become a thing, this should also allow for erlang actor model. https://bit.ly/3WhSF0P July 25, 2024 at 08:15AM

Show HN: Hooper – AI-driven stats and highlights for basketball play https://bit.ly/3Ygz6so

Show HN: Hooper – AI-driven stats and highlights for basketball play Hey everyone, OP here. Wanted to share a bit more about Hooper — I started building it with a good friend of mine six months ago. We play a lot of pickup together and were arguing about who has a better jump shot and ended up hacking together an app to settle it The way Hooper works is you can record yourself using the app and ideally a tripod (optional). The app will track everyone, whether its a solo practice, a 3v3, or a 5v5. We think there’s a lot of stuff out there for basketball drills but what we really wanted Hooper to be for is actual game play. That means, it can do things like track multiple players, sync two half court recordings, and differentiate 2s vs 3s. Once you finish recording, it’ll process for a bit and then ask you to tag yourself (and optionally other players). Then it spits back out a few things: you can watch the full footage as well as a clipped version that's only the interesting plays; you can see highlights and offensive box stats for every player. When you sign up, you get a Hooper profile that tracks your overall stats across the sessions. You can also do things like build a mixtape from your highlights for insta. You can friend other players on Hooper to see their profile & comment on their games (also add us “grub” and “kangexpress”!) We’ve been in a closed beta for about 3 months now, fixing bugs and getting things to work with a set of early adopters. We are now starting our open beta ! If anyone here wants to try it out, you can just download the app on https://bit.ly/3WBHwcI . We are early in our journey, and lots of improvements to be made in the next few months, but we would love your feedback and ideas! https://bit.ly/3y0TfZ3 July 24, 2024 at 10:39PM

Show HN: Track live mentions of any keyword on any forum + Twitter https://bit.ly/3Yi7rrg

Show HN: Track live mentions of any keyword on any forum + Twitter Hey HN! My name's Josh and I'm the sole founder of ForumScout. I had the idea for this project about 3 months ago, and I've been building it ever since. ForumScout notifies you whenever your chosen keyword(s) are mentioned on ANY forum or Twitter thread. For example, let's say you own a SaaS that generates AI headshots. You could get notified when someone mentions "AI headshot", and offer them a free trial of your service. There are many ways I believe a tool like this can be useful, but a few of the obvious ones are: - Respond to mentions of your brand/website in real time. - Find people who mention keywords related to your niche, and engage with potential customers. - Monitor mentions of your competition, and pick the right moments to offer your alternative. - Get creative. You can track live mentions of literally anything, anywhere on the internet. When new posts are found, they will be added to the feed in your dashboard. Email notifications are optional, but will help you engage much faster. Data is pulled from various different real-time Forum APIs, as well as a few native platform APIs, like Reddit. I also built a free search engine so you can search for past mentions if you don't need live ones: https://bit.ly/4dbR97o The search engine works differently from the live service, so it might miss quite a few posts - the live service doesn't miss any. Right now, there's a 2 week free trial that lets you setup 5 of these automations for free. If you'd like a longer trial period, please email me at josh@forumscout.app and I'd be more than happy to extend it for you in return for your feedback:) If it sounds like something you're interested in, I'd be extremely grateful to hear your thoughts. I'm considering adding new features and looking for direction. https://bit.ly/4dbRabs July 23, 2024 at 11:04PM

As a developer, I found existing solutions lacking in consistency and quality, so I decided to build my own. The app uses fine-tuned stable diffusion models to create realistic, professional-looking headshots suitable for LinkedIn profiles, company websites, or any other professional use. This is the result of a lot of experimentation around this to get to a decent quality. The goal has been quality and faithfulness to uploaded images. I'd love to get your feedback on the user experience, technical suggestions or any other aspects of the project. What do you think about the current state of AI-generated images for professional use? Are there any features you'd like to see added? I'm also happy to answer any questions.

Now, how many of you have the same "Book a Demo" form on your website? It seems like lead forms are inevitable, right? But nobody likes to fill out those forms. So we built a better alternative for Devtools go-to-market approach at Chirp. Chirp streamlines collaboration between developers and sales engineers by creating dedicated Slack channels, enabling them to work together seamlessly and close deals faster. We don't take any data out of Slack and don't even ask for permission to read the conversations. Chirp's only task is to automate channel creation between the anonymous website visitor and the sales team on the other side.

You can follow other users on other servers — but sharing links to profiles and posts can be tedious. You can view the content on the origin server, but you need to be on the server hosting your account to boost, favorite, or follow. Much like how the mailto: link opens your preferred email application to let you email anyone, fedv.link links are designed to easily open ActivityPub posts and profiles in the end user's preferred server. https://bit.ly/3zGZXnp July 13, 2024 at 01:51AM

Show HN: Dut, a fast Linux disk usage calculator https://bit.ly/3XU2pB3

Show HN: Dut, a fast Linux disk usage calculator "dut" is a disk usage calculator that I wrote a couple months ago in C. It is multi-threaded, making it one of the fastest such programs. It beats normal "du" in all cases, and beats all other similar programs when Linux's caches are warm (so, not on the first run). I wrote "dut" as a challenge to beat similar programs that I used a lot, namely pdu[1] and dust[2]. "dut" displays a tree of the biggest things under your current directory, and it also shows the size of hard-links under each directory as well. The hard-link tallying was inspired by ncdu[3], but I don't like how unintuitive the readout is. Anyone have ideas for a better format? There's installation instructions in the README. dut is a single source file, so you only need to download it and copy-paste the compiler command, and then copy somewhere on your path like /usr/local/bin. I went through a few different approaches writing it, and you can see most of them in the git history. At the core of the program is a datastructure that holds the directories that still need to be traversed, and binary heaps to hold statted files and directories. I had started off using C++ std::queues with mutexes, but the performance was awful, so I took it as a learning opportunity and wrote all the datastructures from scratch. That was the hardest part of the program to get right. These are the other techniques I used to improve performance: * Using fstatat(2) with the parent directory's fd instead of lstat(2) with an absolute path. (10-15% performance increase) * Using statx(2) instead of fstatat. (perf showed fstatat running statx code in the kernel). (10% performance increase) * Using getdents(2) to get directory contents instead of opendir/readdir/closedir. (also around 10%) * Limiting inter-thread communication. I originally had fs-traversal results accumulated in a shared binary heap, but giving each thread a binary-heap and then merging them all at the end was faster. I couldn't find any information online about fstatat and statx being significantly faster than plain old stat, so maybe this info will help someone in the future.

Show HN: Open-source tool that writes Nvidia Triton Inference Glue code for you Triton Co-Pilot: A quick way to write glue code to make deploying with NVIDIA Triton Inference Server easier. It's a cool CLI tool that we created as part of an internal team hackathon. Earlier, deploying a model to Triton was very tough. You had to navigate through the documentation for the Python backend, figure out how to get your inputs and outputs right, write a bunch of glue code, create a config.pbtxt file with all the correct parameters, and then package everything up. It could easily take a couple of hours. But with Triton Co-Pilot, all that hassle is gone. Now, you just write your model logic, run a command, and Triton Co-Pilot does the rest. It automatically generates everything you need, uses AI models to configure inputs and outputs, and handles all the tedious parts. You get your Docker container ready to go in seconds. Check out our GitHub repository and see how much easier deploying to Triton can be! It would be great if you folks try it out and see if it works for you. reply https://bit.ly/4cSXLYa July 10, 2024 at 11:54PM

Show HN: Tegon: Open-source alternative to Jira, Linear https://bit.ly/3XWMfaa

Show HN: Tegon: Open-source alternative to Jira, Linear Hi HN, we're Harshith, Manoj and Manik and we're building Tegon ( https://bit.ly/4ae9uir ), open-source issue tracking software that uses AI to smartly automate manual workflows or provide more context to engineers for a given task. There's a demo video here: https://bit.ly/3VUqiWA , and you can try out the product at https://bit.ly/3XQMaVl using these credentials: Email: elon@xyz.com Password: XfFNw6GwVJVQv6PA As engineers, our experience with traditional tools like Jira hasn't been great. It is slow, bloated and often acts as a burden to engineers. These tools didn't help engineers in getting the work done faster, they only helped the management in tracking the work which enabled a lot of processes and micro-management which used to kill our productivity. With the rise of LLMs, we thought about how project management and issue tracking would look 5-10 years from now. The current tools didn't match our vision, which excited us and started the journey of Tegon. We aim to build a tool where manual workflows are either automated or handled by AI. This tool will provide better context about a task to an engineer by smartly gathering data from all sources, helping teams with better prioritization. Tegon loads all the data from local (indexed db) thus making it super fast to load and navigate. We make all of this happen by real-time sync in the background. Tegon also uses AI to simplify the issue-creation process by automatically creating titles, suggesting labels and assignees and identifying duplicates. Tegon also simplifies the issue creation process from Slack, just apply an emoji to a Slack message and a tegon issue will be created making it easier for other teams to raise bugs or feature requests to engineering teams. We deeply value the feedback from this community and have spent the last month revamping Tegon's design based on the feedback from our last launch. We just got started and there's a lot more to come. We're eager to get more feedback and keep building. Let us know what you think in the comments :) https://bit.ly/4ae9uir July 9, 2024 at 07:01AM

Show HN: Open-sourced Webflow for your own app https://bit.ly/3xDxyy1

Show HN: Open-sourced Webflow for your own app Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your localhost, which injects some CSS into the page that allows you to select, drag, and drop DOM elements, then track and translate those changes back into React code. Theoretically, you could do this with any compiled framework but I wanted a reasonable scope for the launch (the first version was actually in Svelte). Some interesting challenges: 1. There is a React parser that is used to parse, insert the style, and serialize it back to code 2. There is a React pre-processor that traces the DOM elements to the corresponding code 3. There's also CSS parsing, injection, and converting to Tailwind 4. This is also an Electron app so there’s a browser within a browser within a node app which makes message passing… interesting What’s next? We’ve already built a proof-of-concept for inspecting and selecting layers, dragging to reorder, and inserting new DOM elements that I’m working on porting over from our private codebase. We’re also exploring opening more tabs in new frames in order to A/B test the changes before committing to code. There’s a long tail of exciting features we can do but I want to put this out there first and see what others would need. Let me know what you think/feedback. It's been a blast working on this so far and I think it’s just neat :) https://bit.ly/3LgUtSG July 8, 2024 at 01:36PM

Show HN: I made a tool that automates competitor research for startups/hackers Hi HN! After months of coding in my free time, I wanted to share Competitor Research [ https://bit.ly/3LgmOc2 ], a tool that helps you find and research your competitors. Problem: Most competitor analysis tools are 1. Time consuming: These tools get you the data, but you still have to do the work of knowing what to look for 2. Expensive: Most tools like Ahrefs, SEMRush cost $99+/month. Other more niche tools can cost $1000+/month. For enterprise software it can be $100K+, for consultants, it can be ~$2K+ 3. Requires you to know who your competitors are 4. Not comprehensive: Mostly provides only SEO related info/social media information 5. No actionable insights Solution: We tried our best to help startups/solopreneurs/makers get the best possible experience when researching their competitors. Here’s what we ended up making: 1. We help you find your competitors by combining several different sources and ranking the ones most relevant to your business. 2. We use multiple data sources and provide a comprehensive overview of your company: 1. SEO Keywords - what keywords do your competitors rank for 2. Backlinks - who’s linking to your competitors 3. Pricing - what your competitor’s pricing model is 4. Traffic - where they get traffic from 5. Website performance - how does your competitor’s website perform 6. Target audience and messaging 3. We provide you with actionable insights, things you can do to improve your business (get more customers, improve pricing, improve copy) 4. It’s a one time fee of $79, which is a steal compared to other tools Thanks a lot for reading through this :) We'd love to hear any feedback/comments you might have!

Show HN: Sonatino – small audio dev board based on ESP32-S3 https://bit.ly/3zue9zV

Show HN: Sonatino – small audio dev board based on ESP32-S3 Hi! My name is Ben, and I recently updated my audio dev board "Sonatino" after receiving a lot of good feedback from the initial launch a year ago. I began working on this after building a few projects that required audio capabilities. I was getting tired of wiring up external DACs and amplifiers to ESP32 boards, so I decided to look for a more compact, integrated solution. The available options either had larger footprints, non-standard connectors, or features that I didn't typically need for my projects. That's when I started working on a custom PCB that could be a sort of "audio swiss army knife". The result was Sonatino. Some have criticized the use of a DAC and ADC that support HD sample rates and bit depths, especially when other factors will limit the usefulness of anything over 44.1kHz/16-bit audio. I actually agree - HD audio in this context is mostly overkill, but most modern audio chips support it and it's entirely optional. My primary goal was for the ADC and DAC to be easy to use - no I2C configuration required (like many of the CODECs available). It needed to be easy to use from an Arduino programming environment. The chips I selected (from Cirrus Logic) were a good fit; they just also happened to support higher sample rates / bit depths. The latest revision drops the built-in antenna in favor of an external one. It also has a better speaker amp (3.2 W), an RGB LED, and improved power circuity. It's been a fun little board to work with! https://bit.ly/3VThf7Y Check it out and let me know if you have feedback. Price is currently higher than I'd like, but that's a result of it being manufactured at low volumes. July 1, 2024 at 09:07PM

Show HN: Jb / json.bash – Command-line tool (and bash library) that creates JSON https://bit.ly/4cqxssA

Show HN: Jb / json.bash – Command-line tool (and bash library) that creates JSON jb is a UNIX tool that creates JSON, for shell scripts or interactive use. Its "one thing" is to get shell-native data (environment variables, files, program output) to somewhere else, using JSON encapsulate it robustly. I wrote this because I wanted a robust and ergonomic way to create ad-hoc JSON data from the command line and scripts. I wanted errors to not pass silently, not coerce data types, not put secrets into argv. I wanted to leverage shell features/patterns like process substitution, environment variables, reading/streaming from files and null-terminated data. If you know of the jo program, jb is similar, but type-safe by default and more flexible. jo coerces types, using flags like -n to coerce to a specific type (number for -n), without failing if the input is invalid. jb encodes values as strings by default, requiring type annotations to parse & encode values as a specific type (failing if the value is invalid). If you know jq, jb is complementary in that jq is great at transforming data already in JSON format, but it's fiddly to get non-JSON data into jq. In contrast, jb is good at getting unstructured data from arguments, environment variables and files into JSON (so that jq could use it), but jb cannot do any transformation of data, only parsing & encoding into JSON types. I feel rather guilty about having written this in bash. It's something of a boiled frog story. I started out just wanting to encode JSON strings from a shell script, without dependencies, with the intention of piping them into jq. After a few trials I was able to encode JSON strings in bash with surprising performance, using array operations to encode multiple strings at once. It grew from there into a complete tool. I'd certainly not choose bash if I was starting from scratch now... https://bit.ly/3zph1y1 July 3, 2024 at 11:18AM

Show HN: Improve LLM Performance by Maximizing Iterative Development https://bit.ly/4cN3vT8

Show HN: Improve LLM Performance by Maximizing Iterative Development I have been working in AI space for a while now, first at FAANG with ML since 2021, then with LLM in start-ups since early 2023. I think LLM Application development is extremely iterative, more so than any other types of development. This is because to improve an LLM application performance (accuracy, hallucinations, latency, cost), you need to try various combinations of LLM models, prompt templates (e.g., few-shot, chain-of-thought), prompt context with different RAG architecture, different agent architecture, and more. There are thousands of possible combinations and you need a process that let’s you quickly test and evaluate these different combinations. I have had the chance to talk with many companies working on AI products. The biggest mistake I see is a lack of standard process that allows them to rapidly iterate towards their performance goal. Using my learnings, I’m working on an Open Source Framework that structures your application development for rapid iteration so you can easily test different combination of your LLM application components and quickly iterate towards your accuracy goals. You can checkout the project at https://bit.ly/3xHAzx4 You can locally setup a complete LLM Chat App with us with a single command. Stars are always appreciated! Would love any feedback or your thoughts around LLM Development. https://bit.ly/3xHAzx4 July 3, 2024 at 02:52AM

Show HN: I created an After Effects alternative https://bit.ly/4clXGfT

Show HN: I created an After Effects alternative Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training. https://bit.ly/4bzcmak July 1, 2024 at 09:57AM
