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/7Sst1li February 27, 2023 at 06:38PM

Show HN: Collect and search robotics data with SensorSurf We've been building SensorSurf and are thrilled to share our beta with the robotics community: https://ift.tt/gcYUhvO . SensorSurf is an open source platform that makes it easy for robotics engineers to collect and search data from their fleet. You can define triggers for when to record data (e.g. emergency stop) and capture the moments leading up to the event with rolling buffers. We integrate directly with ROS. Drop our agent into your system, and start collecting data! ================= What prompted me to found this company: > I was a perception engineer working on autonomous boats. > I needed tons of imagery to build computer vision datasets. > It was impossible to offload all this data over satellite. > I interviewed robotics companies, and learned this was a common problem. ================= Our beta enables you to: 1. Trigger recording on arbitrary ROS topic data. 2. Capture the data leading up to the tri...

Show HN: Crul – Query Any Webpage or API Hi HN, we’re Carl and Nic, the creators of crul ( https://www.crul.com ), and we’ve been hard at work for the last year and a half building our dream of turning the web into a dataset. In a nutshell crul is a tool for querying and building web and api data feeds from anywhere to anywhere. With crul you can crawl and transform web pages into csv tables, explore and dynamically query APIs, filter and organize data, and push data sets to third party data lakes and analytics tools. Here’s a demo video, we’ve been told Nic sounds like John Mayer (lol) ( https://ift.tt/FfoCKpL ) We’ve personally struggled wrangling data from the web using puppeteer/playwright/selenium, jq or cobbling together python scripts, client libraries, and schedulers to consume APIs. The reality is that shit is hard, doesn’t scale (classic blocking for-loop or async saturation), and comes with thorny maintenance/security issues. The tools we love to hate. Crul’s value prop is s...

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: Starter.place – Gumroad for Starter Repos Hey HN! 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/sy4iJGP February 22, 2023 at 03:58AM

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: 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...

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.

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: Channel 784, infinite AI generated fake news I was inspired by Nothing Forever to make something while it's off air - Channel 784. It's a parody of evening news. How it works: I have a Node server that generates headlines, then expands each one and creates an intro and outro based on them, and then passes the headlines to DALL-E to generate pictures for each story and the stories to Google Cloud to generate speech. Then I save that as a JSON and load it into Unreal Engine. I'm not sure it's as funny as Nothing Forever, it's a bit more structured. If anyone's got any suggestions I'd love to hear them. https://ift.tt/45uNdqS February 12, 2023 at 10:35AM

Show HN: Experimenting with GPT-3: Building an Investment Analyst We have been experimenting with using GPT3's reasoning capabilities to build an investment analyst that does this : (1) Summarize relevant news of the last 30 days, (2) Write a SWOT analysis, (3) Identify competitors, (4) Identify Key Risks, and (5) Write three investment theses (bull, neutral, bear) Here is an example how this can look like: https://ift.tt/QcBSgqy https://ift.tt/7dmcYIH https://ift.tt/WLgAHBV https://ift.tt/5uD6yR2 So far, the results of getting reliable data back through well-engineered prompts through the API is quite promising.

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: PodText.ai – Search anything said on a podcast, highlight text to play Hi HN, wanted to share a project that I’ve been working on recently. PodText allows users to find anything said on a podcast. You can also listen and share clips to a specific part of the podcast audio, simply by highlighting the text of that part. Currently there are just over 25k podcast episodes and I’m adding a lot more in the coming weeks (yes my GPU bill is painful). In order to monetize it, I’m building a sponsorship database to help sponsors find podcasts and vice versa. This will be sold in the form of a $99/month “PodText Business” subscription. I bet I could charge a lot more to large sponsors but I’ll tweak that as I talk to potential customers. Right now the UI is very bare bones (doesn’t even have pagination) but I’ll polish it once the data pipeline is working well. Please let me know if you run into any bugs or have any questions about the site or business model. https://podtext.ai February ...

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/aGhvd70 February 8, 2023 at 08:34PM

It's been used in huge movies like "Everything Everywhere All At Once". It's been a huge rewrite to get this working on Linux and Windows from our original Mac and Metal code. We also have some interesting uses of cross-platform Swift + Electron in our plugin manager app, and cross-platform Swift generally in the plugin. Hopefully we can detail that in a blog post at some point. There's a free Filmbox Lite version to try, if you're interested. https://ift.tt/gplbUM0 February 9, 2023 at 12:43AM

Show HN: We built an open-source LaunchDarkly alternative for B2Bs Hey HN, Nir, Gal and Tomer here. Last week, we open-sourced Enrolla ( https://ift.tt/AG1JlO6 ) - feature management for SaaS companies. It makes it easy for developers to control how their product behaves for customers in different pricing tiers. So things like which features are enabled for whom, rate limits and seat limits, but also your customer secrets (with end-to-end encryption), and other configurations. After 15 years of working together at various companies, where we rebuilt the same SaaS foundation layer again and again - we wanted to create something reliable and feature-rich that will be available for everyone. We now have a backoffice UI, a backend and SDKs for managing customer features and a way to manage pricing tiers on top of it. We plan to add more features around metering and integration with Stripe, so that ideally Enrolla can be used to bootstrap any new SaaS software in minutes. We’ve launched thi...

Show HN: Embra – A fast, Chat-GPT like assistant for your Mac. App integrated Hey HN! We're building Embra, an always-one-second away GPT assistant that integrates into your OS, apps, and workflows. Everyone is talking about the "context problem" as it relates to GPT, in that the answers you get out are only as good as the information you put in. And, well, a lot of users don't want to type in a bunch of text. With Embra, you can pick and choose which context to feed the AI within the interface itself. And that context can be anywhere on your computer -- text in a PDF document, any tabs within Chrome, etc. One of the primary use cases is improved coding, debugging, and software workflows. We especially want to gather feedback in this direction, as engineers engage in Q&A workflows and code creation 15+ times a day. Really awesome. :) Just launching our closed beta signup page today, and rolling out first invites to broader community. https://embra.app/ And the twi...

We were thinking how great it would be if people could use ChatGPT to ask questions from their own data. So me and my friends had decided to build such a tool. We are delighted to announce that we are releasing a public beta of our tool> After you upload all your pdf files into it. It can search for relevant documents without perfect keyword match, summarize takeaways from the document specific to your question, and extract key information from the document. It can help with brainstorming and summarization. We would love if you try it out and let us know what you think about it.

Show HN: Open-source platform for customer-facing Salesforce integrations We spent the past few weeks building Supaglue ( https://ift.tt/pn9Wx7l ) and would like to share an early public alpha version with you. Supaglue is an open source platform to help developers build customer-facing Salesforce integrations into their applications. Use code to define syncs for pulling objects from Salesforce into your application. Embed functional and customizable React components for your customers to configure these syncs. Why? - We built user-facing HubSpot and Salesforce integrations in a previous product we worked on and did not find an existing solution that let us build it quickly, using code, and that supported custom business logic, so we built in-house. - There were some unified API products we evaluated, but they lacked depth, e.g. support for custom fields and objects. - There were UI-based workflow builders, but we did not want to click around in a UI tool to author business logic. - No...
