Show HN: Rapid Kubernetes Controller Development with Tilt and Silly Drawings https://ift.tt/8H3hV4d
Show HN: Rapid Kubernetes Controller Development with Tilt and Silly Drawings Like the says. I'm describing how to use Tilt to speed up the dev cycle of testing and coding Kubernetes controllers. Tilt uses a built in local registry to push images into and can use hot swapping to kickly deploy processes in containers. It's pretty neat. :) The Tiltfile can be a bit daunting but I'm trying to break it down as much as possible. :) I hope this helps! Good luck! https://ift.tt/0ouC7Tc March 1, 2023 at 05:38PM

Show HN: Graph-based roadmap to learn anything 10x faster Hey guys, I am founder of Neuton. I have built roadmap playground that guide student to learn skills faster with the help of progress tracking and interactive graph-based roadmap. To read more: https://ift.tt/DVT5JKf... I would love to get some feedbacks. https://ift.tt/fCaKluW March 1, 2023 at 07:25PM
Show HN: Dak – a Lisp-like language that transpiles to JavaScript https://ift.tt/LGSAw9N
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/7SoUqLD February 27, 2023 at 06:38PM
Show HN: Collect and search robotics data with SensorSurf https://ift.tt/x7Bcunw
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/tU3SXlE . 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 trigger (rolling buffer). 3. Offload over a poor connection (set max upload rate). 4. Search imagery with natural language. ================= Open source announcement: https://ift.tt/2uYEoWF https://ift.tt/hF1buDy March 1, 2023 at 12:32AM
Show HN: Crul – Query Any Webpage or API https://ift.tt/75SVopL
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/VJ0tswT ) 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 simple: Query any Webpage or API for free. At its core, crul is based on the foundational linked nature of Web/API content. It consists of a purpose built map/expand/reduce engine for hierarchical Web/API content (kind of like postman but with a membership to Gold's Gym) with a familiar parser expression grammar that naturally gets the job done (and layered caching to make it quick to fix when it doesn’t on the first try). There’s a boatload of other features like domain policies, scheduler, checkpoints, templates, REST API, Web UI, vault, OAuth for third parties and 20+ stores to send your data to. Our goal is to open source crul as time and resources permit. At the end of the day it’s just the two of us trying to figure things out as we go! We’re just getting started. Crul is one bad mother#^@%*& and the web is finally yours! Download crul for free as a Mac OS desktop application or as a Docker image ( https://www.crul.com ) and let us know if you love it or hate it. ( https://ift.tt/I5eSbdQ ) And come say hello to us on our slack channel - we’re a friendly bunch! ( https://ift.tt/NYUyaGP ) Nic and Carl ( https://ift.tt/skKMVHD ) https://www.crul.com/ February 28, 2023 at 09:42PM
