It’s Electric! Battery Buses Then and Now By Jeremy Menzies Battery-electric buses and cars have been hitting the streets around the nation in recent years, and here in San Francisco, the SFMTA is currently running a pilot program to test battery powered buses across the system. The pilot analyzes not only the buses themselves, but also how the technology works in the real world of stop-and-go traffic and hill-climbing.    Surprising as it may seem, this pilot program is not the first time battery electric buses appeared on the streets of SF. Here’s a look back at one test that took place over 50 years ago.  While battery electric vehicles date back nearly 200 years to the 1830s, it took over a century for them to see widespread commercial success due to the limitations of the battery technology.  One of the first times Muni tested a battery-powered bus was in November 1972.  Dubbed the “Electrobus”, this small vehicle was tested on the 39 Coit route up Telegraph Hill. This rout

Show HN: Dolt Workbench – A modern, browser-based, open source MySQL workbench Why are SQL workbenches stuck in 2002? I work for the company behind Dolt, the first fully versioned SQL database. As a database company, we have often felt the pain of the lack of modern, web-native or browser-based SQL workbench products. We built a cool database UI for our other web products (DoltHub and Hosted Dolt) and we wanted the world to have it. The Dolt Workbench not only works with Dolt, which will unlock version control features, but it also works with any MySQL-compatible database, including MySQL and MariaDB. As far as we can tell, the Dolt Workbench is the only free, open source, browser-based SQL workbench available today. We’re actively developing and would appreciate any feedback!

Show HN: Dobb·E – towards home robots with an open-source platform Hi HN! Proud to share our open-source robot platform, Dobb·E, a home robot system that needs just 5 minutes of human teaching to learn new tasks. We've already taken Dobb·E to 10 different homes in New York, taught it 100+ tasks, and we are just getting started! I would love to hear your thoughts about this. Here are some more details, below (or see a Twitter thread with attached media: https://twitter.com/i/status/1729515379892826211 or https://ift.tt/wcUJIxs ): We engineered Dobb·E to maximize efficiency, safety, and user comfort. As a system, it is composed of four parts: a data collection tool, a home dataset, a pretrained vision model, and a policy fine-tuning recipe. We teach our robots with imitation learning, and for data collection, we created the “Stick”, a tool made out of $25 of hardware and an iPhone. Then, using the Stick, we collected a 13 hour dataset in 22 New York homes, called Homes of New York (H

Show HN: Build an open-source computer vision model in seconds using text Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it work? We believe that with the rise of foundation vision models, computer vision will fundamentally change. These powerful models will let any devs “compile” a model ahead of time with a subset of the foundation model’s characteristics, using only text and a web-tool. The days of teams of MLEs building complex models and pipelines are ending. Ze

Show HN: I Wrote a Book on PostgreSQL for Rails Hi HN. As a backend developer using PostgreSQL and Ruby on Rails for more than 10 years, around 3 years ago, I caught a spark to learn as much as I could about how to operate high performance, scalable, and reliable PostgreSQL databases. As I reflected on my own career path, I realized there are other developers that may want to learn more about this. I saw an opportunity to help show backend developers how they could put advanced, powerful, PostgreSQL features to use, to help build and scale their Rails apps.

It's pretty simple to use - just go to https://flawless.is and enter your homepage or landing page URL. I'm using the urlbox API to get a screenshot of your page, then I utilize GPT-4V to analyze the screenshot, find potential usability and conversion issues, suggest fixes, and highlight the relevant areas in the screenshot (although the position is sometimes inaccurate). Last week, I launched it on Hacker News ( https://ift.tt/uNkZhFo ), but I wasn't ready for the 20,000 visitors that came next... Unfortunately, GPT-4V has a rate limit of 100 events daily, so almost no one could use the service - EPIC FAIL.

This project aims to alleviate this. We implement a Docker Socket Proxy which is intended to give a tenant specific view onto a Docker Swarm. It exposes all necessary operations to deploy stacks with all features to Docker Swarm as well as management endpoints for volumes, secrets, configs, networks. Every proxy can be configured with a unique label to give a tenant specific view onto the swarm. This way you can have multiple teams of people collaborate on the same cluster. This is done by filtering all requests on resource labels to check whether the resources are "owned" by the proxy/tenant. This projects uses Node.js and Express for the server, along with the dockerode (and docker-modem) library to interact with Docker. https://ift.tt/FJNmYq7 Nov

Show HN: Nango – Open unified API for product integrations Today customers expect every SaaS product to integrate with the other tools they use. Nango is a tool for engineers at SaaS companies to help them ship integrations fast, without compromising on the integration’s depth and quality. It supports more than 100 APIs out of the box. Other integration companies have focused on building a lot of pre-built integrations. These are fast to ship and low maintenance, but they limit how deeply you can integrate with the external APIs. We take a different approach: we make it easier for developers to build and maintain product integrations in code. This lets you create exactly the integration your customers need without compromising on speed and maintainability, and without having to build complex infrastructure (OAuth, retries, rate-limit handling, change detection, monitoring & logging, alerting, etc.). Our platform has two layers: (1) An API-agnostic infrastructure built with Temporal

Show HN: Reduce Ops by Managing oncalls, tickets, incidents over Slack Hi HN! In all the organisations, we have worked, SDEs and EMs spend a lot of time on on-call, incident operations, ticket operations - Constantly updating everyone on the current status of an incident, figuring out who is the current Oncall in Slack threads like @dev-oncall, Missing following up on Action Items post-incident, creating a post-mortem RCA document, Spending time on creating and analysing oncall reports For each of these tasks, there is a Developer who doesn't like to spend time on these tasks and an Engineering leader who stresses maintaining this culture. This is why we started Pagerly. : We believe Slack is the best place for collaboration, and many of these tasks can be done there effectively given the right workflows. Ex - Sync your Pagerduty/Opsgenie schedule with Slack UserGroup like @dev-on-call - Round Robin rotations on Slack for non-oncall work say @scrum-master - Mention multiple oncalls

Show HN: Gogosseract, a Go Lib for CGo-Free Tesseract OCR via Wazero Tesseract is one of the largest Open Source OCR (Optical Character Recognition) projects. There is already a Go library for using Tesseract from Go with CGo, called Gosseract. However if you are interested in OCR from Go without C complicating building and cross-compiling, there aren't any other options. Wazero is a Go WASM runtime that doesn't have any CGo dependencies. With Emscripten Tesseract has been compiled to WASM and ran within Wazero. Gogosseract provides a simple API on top of this. This project has been an interesting delve into the world of WASM. https://ift.tt/VYnZ2yA November 5, 2023 at 06:06AM

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates). Some key ideas: • It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged templates • A pub/sub store • Easy immutability using immer (it powers the observable updates & also the reducers) It's my first 'serious' library that I'm using in some work prototypes, and it's also my first 'real' open source project, so comments & feedback would be

Show HN: Transforming "Who's Hiring? (November 2023)" Posts into a Google Sheet Hello HN Community! I've transformed the "Ask HN: Who's hiring? (November 2023)" post into a Google Sheet. Here's a quick rundown of the method: I utilized the Hacker News Algolia Search API to extract data. You can find the specific thread URL here: https://ift.tt/o7X6gAK... Using a GET request, I fetched comments from the thread and processed them via the ChatGPT API. Employing the ChatGPT API for each comment, I parsed crucial job details such as company, position, location, and more. This information was structured and appended to a Google Sheets document, creating a neatly organized view of viable job opportunities. I believe this resource can aid individuals in more effectively evaluating job offers or possibly be the foundation for a helpful search tool using this standardized data.

Fair warning, though, this is my first time writing in Rust/Bevy.

I've worked on multiple, multi-year projects which were subsequently shut down by lawyers and, frankly, I'm tired of practicing
