Show HN: Dak – a Lisp-like language that transpiles to JavaScript 20 by daakus | 3 comments on Hacker News. 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!

Free IP to Country and ASN Data downloads: - MMDB, CSV and JSON format - Full accuracy (not degraded quality compared to our paid downloads) - IPv4 and IPv6 data - A single file that includes both country and ASN details - Daily updated - CC Attribution license (no usage restrictions, only requirement is a link back to ipinfo.io) Here's an example of querying the MMDB file using our mmdbctl tool: $ echo "1.1.1.1" | mmdbctl read country_asn.mmdb | jq . { "as_domain": "cloudflare.com", "as_name": "Cloudflare, Inc.", "asn": "AS13335", "continent": "NA", "continent_name": "North America", "country": "US", "country_name": "United States" } Almost 8 years ago I launched the free IPinfo.io free geolocation API, but until now our data

Show HN: Crul – Query Any Webpage or API 34 by portInit | 7 comments on Hacker News. 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/MDvYlFy ) 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. Th

Show HN: DbDeclare – A Python declarative layer for your database 2 by falafelite | 0 comments on Hacker News. 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 a

Show HN: Atlantis workflow without a backend 2 by ujnproduct | 0 comments on Hacker News. 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).

Show HN: We’re open-sourcing our session replay tool 7 by podoman | 0 comments on Hacker News. Hey HN! We’re open-sourcing highlight.io ( https://ift.tt/Z9Ag7Vr ), 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 (

Show HN: Liftosaur – Weightlifting tracker app for coders 7 by astashov | 0 comments on Hacker News. I made a weightlifting tracker app specifically for coders. In weightlifting, progressive overload is one of the most important parts of gaining muscle. You should constantly increase weights, reps, use different set schemes, and that will make your muscles grow. There're many weightlifting programs, using various overloading schemes - linear increasing of weights, some periodic ladder-up increase, switching to different set schemes in case of failures, etc. You can implement all of that in Liftosaur. It works this way: each exercise may define a bunch of variables, that could be changed when you finish a workout. It could be weight, your 1 rep max, number of successful attempts, etc. You can use those variables in reps and weight values. To update the variables, you define a script, that will change them after you've done all the sets of the exercise. The script may change t

Show HN: Starter.place – Gumroad for Starter Repos 6 by ecuaflo | 1 comments on Hacker News. 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

Show HN: Strada – Embed accounting automation with one API 4 by aprod | 0 comments on Hacker News. 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!

Show HN: Phind.com – Generative AI search engine for developers 10 by rushingcreek | 0 comments on Hacker News. Hi HN, Today we're launching phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. It's version 1.0 of what was previously known as Hello (beta.sayhello.so) and has been completely reworked to be more accurate and reliable. Because it's connected to the internet, Phind is always up-to-date and has access to docs, issues, and bugs that ChatGPT hasn't seen. Like ChatGPT, you can ask followup questions. Phind is smart enough to perform a new search and join it with the existing conversation context. We're merging the best of ChatGPT with the best of Google. You're probably wondering how it's different from the new Bing. For one, we don't dumb down a user's query the way that the new Bing does. We feed your question into th

Show HN: Whisper.cpp and YAKE to Analyse Voice Reflections [iOS] 3 by ArminRS | 0 comments on Hacker News. 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.c

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 tol

We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep ( https://ift.tt/jSJMr1Z ). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process. Think of Keep as Prometheus Alertmanager but for all observability tools, with a simple and intuitive (GitHub actions-like) syntax. 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.

Show HN: Generate User Interface Components with GPT-3 3 by designhat | 0 comments on Hacker News. 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 i

Often times, builders of forms start their process by looking at what other people are doing, answering questions like: What are different ways error validations are done?
