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/xLt43Qi . 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/RewS9rz ) 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

Black History Lost and Found: Dorothy Jaymes and Accessible Transit By Jeremy Menzies We continue to celebrate Black History Month by sharing the stories of SFMTA staff whose revolutionary work helped pave the way for future generations of Muni riders. Today, we look at the incredible contributions of Dorothy Jaymes, who played a critical role in helping advance accessibility on transit in San Francisco at a time when little was being done.   Jaymes (left, holding tennis racket) with her assistant, Linda Westry in the Muni Lost & Found Department in 1977.  Born in Lake Charles, Louisiana, Jaymes started her career in Muni’s Lost & Found Department in the 1970s. According to a 1977  article in the department newsletter, Trolley Topics, she took her job seriously, accounting for every lost item no matter how small or large.  Around the same time, protests by local disability rights advocates exposed the issues of poor access to public transit to local officials. The city r

Show HN: Touca – a better alternative to snapshot testing Hi everyone, Almost 2 years ago, I left my full-time job at Canon to build tooling and infrastructure to help developers write high-level tests for complex software workflows that are not easy to unit test. I wanted to take ideas from visual regression testing, snapshot testing, and property-based testing and build a general-purpose regression testing system that developers can use to find the unintended side-effects of their day-to-day code changes during the development stage. After two years of working ~70 hours per week and going through multiple iterations, we finally have a fully open-source (Apache-2.0) product that finally makes me and other members of our community happy: https://ift.tt/IrOqgME This week we released v2.0, a milestone version that is useful to small and large teams alike. This version comes with: - An easy to self-host server that stores test results for new versions of your software workflows, automatic

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: Power-Performance Curves for CPUs Hi HN! Following the release of the latest generation of CPUs by AMD and Intel with rather high power requirements and the corresponding uptake in interest of undervolting / power level adjustment, I was interested to find out in more detail how these CPU models would perform and compare at different power settings. However, it couldn't find an online source that would provide a satisfactory amount of data to be really useful to compare different models. So I took what data I could find to set up a Bayesian regression model. Find the results and more details on the linked page. Hope this is useful or of interest. Any feedback is welcome. Especially great would be if someone knows a source for or would be able and willing to contribute data for more CPU models (especially Intel 13th Gen.).

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

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

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

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.

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

Show HN: Sign-up flows from 100s of websites made publicly available Hi HN! Fil here from Formsort ( https://formsort.com/ ). We just launched Fineflows, a design gallery that showcases leading sign-up flows from around the web. Why? My team has been building sign-up flows for close to a decade across mortgages and healthcare. We’ve spent a lot of time working through the technical and design aspects of this problem, such as state management (getting that pesky back button to work), design flexibility, and data enrichment. Time and again, we’ve seen product teams who don’t know what to build even though they can . 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? Should I use photos of people, or is text enough? Is it appropriate to use emojis in forms? How can I decline a user in a polite yet firm way? To that end, we set out to capture as many different form flows

Show HN: We built a managed Kubernetes provider at half the cost of AWS Since there’s a few discussions recently on $4 VPSes we thought you might be interested in Symbiosis, a cheaper and simpler managed k8s provider. Supported features include external LBs, encrypted+replicated storage and autoscaler. Infrastructure can be managed with UI, CLI, Terraform or Pulumi. Control planes are free of charge and a 1vCPU/2GB node goes for $6 per month. We’re live in Germany right now and we’re expanding into US during 2023. Feel free to try it out and leave a comment. https://symbiosis.host/ February 14, 2023 at 12:04AM

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: 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/LsUoO7v February 12, 2023 at 03:44AM

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
