Show HN: Dak – a Lisp-like language that transpiles to JavaScript Hi HN, author here. Happy to answer any questions. I had an itch to make a lisp like language that was a thin layer on top JavaScript. Something that could leverage the thriving ecosystem that exists around JavaScript. It's brittle, hot off the oven. Besides being a fan of parenthesis, I think macros fill in a gap that the JavaScript ecosystem today fills in with one-off compilers, bundler plugins and such. Macros can't do everything, but for example I think they have the potential to enable things like JSX, Solid and Svelte style libraries. Take the tour to get a feel for what it can do and play with the live code in your browser! https://ift.tt/VRoiwLb February 27, 2023 at 06:08PM

Show HN: DbDeclare – A Python declarative layer for your database Hi HN! I made and just published v0.0.1 of DbDeclare. I use Python a lot, and interact with Postgres a lot. I like using SQLAlchemy, and I love Alembic. Those wonderful tools primarily operate on tables, though, and I often find myself writing custom code to declare what databases, roles, schemas, privileges, etc. I want, and I have a hard time updating them reliably and in a repeatable fashion. That's where DbDeclare aims to help: declare what you want in your cluster (in addition to SQLAlchemy-defined tables and columns) in-code, alongside your tables. There is a lot this can't do yet (thus the v0.0.1), but I think there's a decent foundation here to build on and eventually have really nice features like autogenerating change statements between your in-code definition and what is actually in your database cluster (like Alembic). This is also my first attempt at building an open-source project, so I'm su...

Show HN: Atlantis workflow without a backend Last week we created a TF cloud alternative that could just run in GH actions and got an overwhelming response on Reddit. A lot of people recommended Atlantis as a way to run terraform plan and apply jobs in your CI. It is used by many great teams (Lyft for example) - however, we see the following issues: - You need to deploy and maintain an Atlantis backend in your infrastructure - It runs terraform commands locally on the same server it is installed in. This makes it tricky to achieve high levels of isolation and repeatability that is typically needed in CI/CD scenarios So we thought: does this really need a backend? Can we somehow make it work without a need to deploy a dedicated service and with terraform jobs running natively in Github Actions with proper isolation? Actually, the only need that makes Atlantis backend irreplaceable is code-level locks (not to be confused with state locks). But these can be stored in a database, accessed ...

Show HN: We’re open-sourcing our session replay tool Hey HN! We’re open-sourcing highlight.io ( https://ift.tt/vdcnRLT ), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..). The main value prop of highlight.io is that we help you understand the full context surrounding an error and allow you to drill down to the code path that a user invoked (i.e user clicked button X, sent network request Y, and backend code Z was executed). Some of our customers compare this to a “web debugger” of sorts. A picture of what this looks like in our app is here [1]. For some background, when we worked at our previous companies as engineers, we encountered hard-to-reproduce issues spanning across both the frontend and backend. The main issues were (1) if a customer complained about a problem, ...

Starting a new project is so hard because before you actually get to building the idea itself, you have to search for tools and figure out how to piece them together. With starter.place, you can find proven starter templates/boilerplates/stacks that use the technologies you want and get to building right away. If you’ve made a starter repo you think others would find useful, you can immediately reach a wide audience without having to make your own site/app to sell it and advertise it by posting on starter.place. Just focus on building the starter all while earning from it if you so choose. starter.place is so helpful to buyers and sellers because buyers are added as view-only collaborators to the repo on GitHub, where they get continuous updates. Buyers can help drive the project by submitting issues and PRs too. Let me know what you think! And if you have a starter template but are hesitant to list it, let me know what I could...

Show HN: Strada – Embed accounting automation with one API Hi HN, we’ve been working on an API that makes it easy to add a full set of accounting tools to your product. If you’re building fintech or payments software for businesses, your customers often ask for integrations to their accounting system (Quickbooks, NetSuite, etc). There’s plenty of options for solving the integration problem, but they leave lots of manual work. Customers still need to review each transaction to assign a category, vendor, department, and tax code. With the Strada API, you can offer accounting integrations, cleanse your transaction data, and automatically map transaction details based on each customer’s accounting setup. We’d love any feedback you have. If you want to chat in more detail please reach out through our website. Thanks! https://ift.tt/DPBrfk5 February 22, 2023 at 03:28AM

Show HN: I'm building ProductHunt for Actual Products: Would love feedback The product discovery process is totally broken, and this is where Styrate comes in. With so many products available online, it's becoming increasingly difficult for consumers to differentiate between genuine and fake reviews. Amazon and other e-commerce platforms are full of fake reviews that can mislead consumers into buying substandard products. This means that consumers can end up wasting their time and money on products that don't meet their needs, and this problem is only getting worse. Styrate solves this problem by connecting consumers with trusted influencers who provide honest reviews and recommendations. With video reviews, upvoting, and sorting/search by type of product, users can easily discover the most highly rated reviews for their needs. Fake reviews cost Americans 0.12 cents on every dollar they spend online, making it crucial to have a platform like Styrate for informed purchasing ...

Show HN: Forte, an open-source self-hosted music platform with lots of features Hey everyone, I've made a project to make your own music archive streamable and turn it into a complete music platform. The reason I've been working on this project for a while was to stream the CD's I've had at home without any cost and also make a nice looking system to manage and listen to these albums. You can host your own server and use the web player to connect. Also, it is possible to create users and give them access to your own server. Some features of the current release are group sessions, endless listening with radio, fuzzy searches, showing lyrics and specialized context menus. This was the first biggest project I've made using Vue.js and I am open to any suggestions. Feel free to leave a comment. I really appreciate your support!

Show HN: Whisper.cpp and YAKE to Analyse Voice Reflections [iOS] Six months ago, I went full-time indie, but I haven't released anything so far. The products just never felt good enough for me to publicly say this is what I'm doing now. To get out of this mindset, I decided to make an app for myself in a week, add monetization, release it and move on. The app idea was simple: Reflect on your day by answering the same four questions out loud. The answers are transcribed and with regular use you can see what influences you the most and take action. All on-device, as otherwise I wouldn't feel comfortable sharing my thoughts. I had all core features working within a day by simply modifying an existing example app. However I was dissatisfied with iOS's built-in offline transcription due to a lack of punctuation and the speech recognition permission prompt that made it seem like data would leave the device. Decided to use whisper.cpp [0] (small model) instead. This change, le...

Show HN: AllyDB – An in-memory database similar to Redis, built using Elixir Hey, everyone. I am currently working on AllyDB, which is basically my own Redis, which I am writing in Elixir. Currently, the database is nowhere close to being ready, as you can see in the roadmap, but I am doing my best to add stuff as fast as possible. Currently the implementation is very simple, with an in memory table, an append log persistence system, as well as an interval persistence system as a backup. The database could definitely be optimized further, especially when it comes to persistence, which I am planning to do in the future. I'm also planning to use Rust NIFs for specific tasks for the performance gains over Elixir and BEAM. Writes and deletes are currently asynchronous, but I will add blocking versions of them soon. I am trying to make the system as fault tolerant as possible, and currently everything except the TCP connections are fault tolerant. I'm also working on a TypeScript cl...

We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep ( https://ift.tt/jX6aAcN ). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process.

We believe that alerting has historically been neglected in existing monitoring platforms, leading to subpar alerting practices. With Keep, we aim to change that. Although it's still in its early stages, we would love to get your feedback on our project. Keep provides the following key features: 1. Declarative alerting that can be easily managed and versioned in your version control and service repository. 2. Alerts from multiple data sources for added context and insight...

Show HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG A few months ago, I ordered a Minisforum UM690 for work. For less than 500 bucks, this little beast is equipped with the incredibly powerful 8 cores / 16 threads Ryzen 9 6900HX (4.9GHz) and an integrated RDN2 680M graphics card (the single thread performance of this mobile CPU is just 10% lower than my home 5800X desktop PC). I do some light gaming on my lunch break, and I was pretty impressed by the gaming performance of the 680M. Because of budget constraints at the time of ordering, I could only afford a single stick of Gskill - RipJaws 16 Go DDR5 4800 MHz CL34. I made a few benchmarks on multiple games, but most games I play do not come with a proper benchmark loop, so I used Unigine Superposition Benchmark to make a proper benchmark. Single 16 GB stick, 1080p, medium settings: 3022 (18.85 min fps, 22.61 avg fps, 31.85 max fps) Those results were good for an IGPU, but I saw a few articles saying that having two...

They all about calculations, synchronization with front-end data, and database data, and try to ensure consistency, atomicity, and high response, etc. However, these codes and frameworks have always had problems such as very complicated APIs, incomplete or non-existent ACID, multiple calls to RPC, and non-real-time full or semi-full data landing. So, we created Lockval Engine. An easy-to-use, ACID, distributed, DOP, multi-language support backend engine. Here are some online demos that will give you a quicker understanding of Lockval Engine: [APIdemo] https://ift.tt/Yy8PrKA [playground] https://ift.tt/SX5tzac... https://lockval.com February 13, 2023 at 05:12PM

Show HN: My personal medical knowledge system Since medical school years ago, I have been trying to find way for long term knowledge management and retention. I finally ended up with Obsidian on the desktop, but it's still difficult to access my knowledge anywhere online, until I made my own online wiki. Things that helped me get to this step: 1. "How to Take Smart Notes" 2. Evergreen notes by Andy: https://ift.tt/C78mnZB . This website shows the culmination of my personal knowledge with search bar. The idea is that I should be able to find what I'm looking for within seconds, otherwise the title of my notes are not specific enough or the web of knowledge is not good enough. Most of the notes still have short title style and walls of texts, but the newer notes that I added are in evergreen note style. I'm slowly converting them to permanent notes. Good example pages of permanent notes: https://ift.tt/UnkaL7B https://ift.tt/AuzIVNQ The website is made with Astro fo...

Show HN: I made a game, Tippy Coco Tippy Coco is a volleyball game in the browser. You can play with a friend at the same keyboard, or solo challenge the built-in opponents. As for the tech: it's all TypeScript + HTML5. I did not use a game engine; I just made a game loop with setTimeout and the artwork is all just png's drawn on the canvas. The sound is played through the HTML audio API. Input is watching keyboard events and the Gamepad API. One thing: I know this is 2023 but it's not a game for phones. It's for a laptop or desktop PC with a physical keyboard. It also works ok on an iPad with a physical keyboard. Tippy Coco is free and without ads. The code is available (MIT license) at https://ift.tt/Y0u6ynD https://tippycoco.com February 14, 2023 at 02:53AM

Show HN: Generate User Interface Components with GPT-3 I’m building an experimental tool that can generate a UI component from a high-level text description, i.e. “Design a card for viewing goals in a goal tracking application”. Basically, stable diffusion but for user interface components instead of images. This tool is at best a proof of concept. It currently only generates a single type of component (small cards that have basic info about an object), but the goal is to be able to design entire applications (either in one fell swoop or by piecing together components that the tool generates). The components it generates can be exported as react code. You can also have it modify an existing design. The tool isn't useful yet but it's somewhat fun to play around with. Having it generate a component rather than an entire screen made the problem easier but I'm not sure if there are any users that this would appeal to. I could see it appealing to developers who lack design and C...

Apparently meta has teamed with "Indifi and FlexiLoans" to give unsecured business loans. 1. They are sharing details of "this user is a small business owner" with third parties and that they are directly emailing about "helping businesses in need". What the hell is wrong with these people.

Show HN: I made a community-based writing application Hi HN! Writing has been a big part of my life for the last few years. It's helped me make sense of the world around me through journaling, and my blog and technical books have made wonders for my career as an engineer. Something I've always been missing is an online community where I can practice my skills and learn from other aspiring writers. I built Tavern, hoping to solve my own problem. Its main concept is that every Monday everyone in the app gets asked the same writing prompt and you have seven days to submit your answer. You can look at what others have posted, but only after you've submitted your answer. My hope is that this way I will reduce lurking and encourage more people to actually write rather than think about it. There is a concept of giving likes (ales, since the whole app is tavern-themed), but I've given it a twist by not showing the number of likes an answer has until you like it. Also, answers a...

Show HN: G-Script – Visual Scripting for the Web Hi all, I'm a PM by day who taught themselves to code over COVID. One of the things I enjoyed during that process was learning how to make basic games in Unreal Engine using Blueprints. I found visual scripting was such an intuitive way to express what I call "mid-tier complexity" logic and I felt there really wasn't a great equivalent for the web - so I built one over the last few months and this is my MVP. Tools like Zapier etc are great and easy to use, but they're heavily limited when it comes to expressing any kind of complex logic or trying to follow coding principles like DRY. On the other end of the spectrum, serverless setups like Cloudflare workers or Firebase functions give you all the power of code, but there's atleast 20-30 minutes of additional overhead involved in just getting the things live. G-Script is designed to land exactly in the middle of these two options. It's "Lower level"...

Show HN: Log collector that runs on a $4 VPS Hey guys, I'm building erlog to try and solve problems with logging. While trying to add logs to my application, I couldn't find any lightweight log platform which was easy to set up without adding tons of dependencies to my code, or configuring 10,000 files. ErLog is just a simple go web server which batch inserts json logs into an sqlite3 server. Through tuning sqlite3 and batching inserts, I find I can get around 8k log insertions/sec which is fast enough for small projects. This is just an MVP, and I plan to add more features once I talk to users. If anyone has any problems with logging, feel free to leave a comment and I'd love to help you out. https://ift.tt/WuLgHIx February 12, 2023 at 01:44AM

Show HN: Noya (YC W21) – A wireframing tool that generates designs and code Hi HN! We’ve been building a new browser-based design tool that’s ready for you to play with! My cofounder David and I were previously on the Design Tools team at Airbnb, where we built lots of innovative tools to improve the design process internally. Now we’re trying to bring this caliber of tools to everyone. The first problem we’re trying to solve is the age-old problem of working in low fidelity vs. high fidelity when designing UI. Low fidelity wireframes are great for quick iteration while hashing out the main idea, while high fidelity mockups and prototypes are often better for conveying the idea to teammates or pitching the idea to customers. With Noya, you get to work in low fidelity, while still getting a high fidelity output you can share. Noya does this by converting your low fidelity blocks into high fidelity design system & React components. I think of the current version as an MVP still, sinc...

Show HN: ListLang – Learn Languages to Fluency Depending on the language, the top 1,000 most frequently used words account for ~85% of all speech and text, and the top 5,000 account for ~95%. It’s really important to learn these words. Learning words in context helps you naturally understand their meaning and use cases, while avoiding the rote memorization of definitions. ListLang helps you achieve fluency by learning the 5,000 most frequently used words in context. Most language learning apps never move past beginner level content. This method requires some basic knowledge, but otherwise it should rapidly increase your level past the intermediate level and into the advanced level. I built this app because I studied Spanish and Russian for many years in school, but when I traveled to Argentina and Russia, I realized I didn’t know enough vocabulary to meaningfully communicate with the people there. I hope it will be helpful for you. https://ift.tt/YP4QswF February 8, 2023 at 08:04PM

Show HN: One API Key – Third-Party API Integrations with Zero Setup Hey HN, we’ve been working on a way to simplify authentication with third-party APIs. This started because my co-founder andreterron ( https://ift.tt/wDlQJOz ) and I both built personal dashboards to track different health and productivity metrics, but it’s such an annoying chore to integrate with new APIs. First you read their docs to learn their authentication method, then build and deploy a custom server to receive OAuth callback requests or deal with CORS, register an app with them, then finally you can send the first request to their API. After the initial integration is done, you now have to refresh expired tokens, make sure that you’re respecting rate limits, and update the code if the underlying API changes. The solution we came up with is a proxy server, it forwards requests to the respective API with up to date auth tokens. Because of this: - Devs can use the full range of capabilities of the underlying APIs....
