Show HN: Platform for building Gen-AI applications on Spark https://ift.tt/IcAKziC

Show HN: Platform for building Gen-AI applications on Spark Hey HN, I'm Maciej, one of the co-founders of Prophecy ( https://prophecy.io ) - low code for Data Transformations and Generative-AI. We've just released the latest version of our product, which makes it easier for teams to build data pipelines for LLM-based applications. As part of the release, we're also open-sourcing the toolbox for Spark ( https://ift.tt/UvcjBwV ) that contains useful connectors, transformations, and agents for building Gen-AI applications. Hopefully, this allows some of you to build your apps easier and make them more robust and scalable from day one. Quick getting started example available here: https://ift.tt/UDdPIQy (all code is open-source too). While our product is already mature, the toolbox shared above is still in a pretty early stage but will be completely OSS. Any thoughts on the concept and ideas for what's important to the community would be super appreciated! https://ift.tt/tv4qrHh June 27, 2023 at 05:52AM

Show HN: Automize I hate writing web tests so I wrote a Chrome extension https://ift.tt/n0w71R8

Show HN: Automize – I hate writing web tests so I wrote a Chrome extension Whenever I write my integration tests or writing a script to scrape a website 90+% of my time is spent fiddling around with selectors. I absolutely hate all the test recorders because most of the time their selectors are so bad that it would have just been faster to do it myself. This lead me to create my chrome extension called Automize. It's basically just the chrome dev tools "elements" tab, except you can click specific attributes to hone in on a reliable selector. It will highlight the element live so that you can verify it works before moving it into your code base. https://automize.dev/ June 27, 2023 at 05:00AM

SFMTA and City Supervisors Collaborate on Arguello Boulevard Safety Project

SFMTA and City Supervisors Collaborate on Arguello Boulevard Safety Project
By Alejo Alvarado

Safety improvements are coming to the full length of Arguello.

Arguello Boulevard is getting a safety upgrade. The SFMTA has begun work on the Arguello Safety Project to improve safety for everyone, particularly people who ride bicycles on Arguello Boulevard. The project covers Arguello between Golden Gate Park and the Presidio.  

District 1 Supervisor Connie Chan and District 2 Supervisor Catherine Stefani called for protected bike lanes on Arguello Boulevard after a San Francisco bicyclist was struck and killed on Arguello in the Presidio on April 4, 2023. Supervisors Chan and Stefani each awarded the SFMTA $50,000 of Community Response Team funding to support safety improvements to Arguello Boulevard within city limits. In addition to this $100,000, the SFMTA will put money into the project, and staff will work closely with both Supervisors and the public to develop a comprehensive design that prioritizes safety on Arguello. 

Arguello Boulevard currently has bike lanes in both directions. However, this project will review and potentially propose protected bikeways that are separated from motor vehicle traffic by parked cars, safe-hit posts, transit islands or other physical barriers. These protective elements can make the street safer for bicyclists. 

The entirety of Arguello Boulevard previously was on the High Injury Network, the San Francisco streets where fatal and severe traffic collisions occur most. Safety improvements were made on one section of Arguello in 2017, but the corridor north of Geary Boulevard remains on the HIN. This project will help address the need for further safety improvements and expand safety and connectivity on the citywide bike network while helping the city meet its Vision Zero goals. 

Designs are currently being considered and the outreach/feedback period is expected to begin in Summer 2023. SFMTA staff is also coordinating with the San Francisco County Transportation Authority as that agency concurrently works on a District 1 Multimodal Transportation Study and a District 2 Safety Study and Implementation.

Show HN: New Beautiful Desktop and Web UI/Monitoring for Apache KafkaKinesis https://ift.tt/QpASZaR

Show HN: New Beautiful Desktop and Web UI/Monitoring for Apache Kafka+Kinesis Hey folks, I'm super excited to announce the release of a new UI for Apache Kafka, Confluent, Redpanda and Kinesis that focuses on Teams and Data Mesh. (Note: the desktop version is also very popular with individual developers!) Why is this important? Because providing a solution that can be used by both IT and business (non-technical) users is essential when building applications that process business data. Of course, we are mainly developers working on Kadeck. So you won't miss any of the features you need to troubleshoot and monitor Kafka and your applications. In fact, we have put a lot of effort into making Kadeck the best UI for Apache Kafka on the market. This includes enterprise features such as fine-grained rights management, topic organisation with data owners, labels and topic (API) documentation, teams and roles as well as LDAP/AD connectivity, data policies and masking, audit log and much more. I hope you enjoy using Kadeck - either the free version or the Professional/Enterprise version - and please let me know your feedback. I always love to hear about your specific use case! Have a great day, Ben https://www.kadeck.com June 27, 2023 at 04:14AM

Show HN: Wolfia Codex Ask anything about any code https://ift.tt/VhpaHtz

Show HN: Wolfia Codex – Ask anything about any code Hi HN, we’re excited to show you Wolfia Codex (wolfia.com). Wolfia Codex allows you to ask any question you want to any codebase. Unlike using a generic tool like ChatGPT, we provide context to the LLM by retrieving relevant snippets from the actual code. We started by indexing a bunch of popular open source repositories, and you can request your favorite one. We plan to monetize by offering a paid version for private codebases. We do this by using vector embeddings ( https://ift.tt/9fHpIGB ) to index a specific codebase in a vector database. We then use OpenAI’s GPT 4 model with a dedicated prompt that combines your query and the most relevant results, based on similarity from the vector database, as context to provide a relevant response to your question. The answer is generated as markdown to display things like blocks of code. We also let you see the relevant snippets of code used to generate the answer for reference, ask follow up questions, and we have an option to share an answer. My co-founder Naren and I used to lead engineering teams. We often had to stop the team from working on their main project and ask them to write documentation to help onboard new engineers to the codebase. That documentation takes days of work to write and ends up being stale very quickly. Wolfia Codex allows new engineers unfamiliar with a codebase to ask pointed questions without having to always interrupt a co-worker to get answers, nor having to have them write lots of documentation. We would love to hear what you think: don’t hesitate to share good and bad answers in the comments! https://wolfia.com/ June 27, 2023 at 12:52AM
