Show HN: lambdaprompt – build, compose and call templated LLM prompts https://ift.tt/Awq8vIE

Show HN: lambdaprompt – build, compose and call templated LLM prompts For the past few months I've been building a lot of things with LLMs (GPT-3, Codex, etc.) as I've been trying to push them to their limits (especially towards applying them to the tabular data domain) When working on this, I've found there are some common patterns for solving problems (templating, chaining, functional-programming style operations, etc.) As I've iterated, I've come to believe that a functional style interface is likely going to power a new wave of systems I'm calling "prompt-machines"(systems where the core new unit of work is a "named" LLM prompt, extending the "function" concept). Additionally, in order to make the code capable of meta-prompting (where the LLM can write its own templated prompts), I aimed to make the interface and library as simple and lightweight as possible. I think I've achieved my goal, so I'm releasing the library to share with others! I mainly use lambdaprompt in two main ways: (1) to quickly try out "map" applying a LLM prompt against multiple inputs, to see how it behaves on a fixed set of inputs (2) to quickly iterate on a prompt-chain (taking the output of a prompt, and passing it to other prompts) to create complex behavior. An example of (2) that worked quite well is a Text-2-SQL prototype: It generates multiple SQL options, then executes each against the database (if it errors, asks `Codex-EDIT` to fix the errors and retry), then takes the most "consistent" answer as the valid answer. Simply by adding this prompt-chain on top of codex, we saw an improvement from ~75% to ~85% on a spider Text-2-SQL benchmark (On just a small sample of N=200). To increase usability it also ships (extras) with a fastapi app that registers any defined prompts as endpoints directly, and hosts the functions to be directly callable via HTTP-GET requests. This makes it easy to build client-applications off of these prompts, while allowing the prompt itself to be arbitrarily complex (composition of prompts) I hope you enjoy using it! Also, I'm super curious to hear if anyone else has been thinking about LLMs (composing them, building interfaces to them, etc.) in similar ways and what learnings have been (even if not though this library) https://ift.tt/WLYnmVS December 31, 2022 at 02:43PM

I'll also note that there are some different results when I was working in a smaller sample size - the entry "Added 49 volumes of Arkansas, Mississippi, and Tennessee law" was classified as "US politics, Current Events" rather than "Unknown". I do want to note that isn't that bad. Running this: "prompt_tokens":560,"completion_tokens":222,"total_tokens":782 So, this is just a hair under $0.02 to do. Thinking about it, some cleanup can be done by removing the year and media type which could trim a few tokens off the request. December 28, 2022 at 07:30AM

Show HN: Merry Sky, Dark Sky replacement and merry-timeline open source lib Hello HN, This is a website I worked on during the holidays to fill the void of the upcoming dark sky shutdown. For me, the precipitation timeline was a view I was heavily relying on for everyday activities and planning. I had not found any replacement from the various weather apps. When I found pirateweather.net as a backend API, it gave me the motivation to put the pieces together and get back the experience I enjoyed. I then added more functionalities that I think was missing from the website such as a weekly chart view. I've been using the website reliably over christmas holidays. Hope you enjoy it too! Also I open sourced the visual component for drawing the precipitation timeline and you can use it for drawing weather information or any other hourly activities really https://ift.tt/XSKyMdh Interested in your feedback! https://ift.tt/D0nXsNh December 28, 2022 at 04:44AM

Show HN: Eleven – open-source alternative to Codespaces https://ift.tt/NjHO4Yu

Show HN: Eleven – open-source alternative to Codespaces Hey HN, Eleven is the second project that I've built to learn Go. It lets you create a code sandbox in your cloud provider account easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it to deploy your app, as a remote development environment or even to test some code. It's up to you. For example, to deploy a Node.JS app: $ eleven aws init hello-world --runtimes node@18.7.0 --repositories eleven-sh/hello-world > Success! The sandbox "hello-world" was initialized. $ ssh eleven/hello-world forever node index.js > Forever: command started. Run "forever stop" in current path to stop. $ eleven aws serve hello-world 8000 --as hello.eleven.sh > Success! The port "8000" is now reachable at: https://hello.eleven.sh $ curl https://hello.eleven.sh > Hello World Still learning Go by the way, so I'm open to any suggestions to improve. https://ift.tt/z3MJTgP December 27, 2022 at 03:57AM

Show HN: TapTab – Tab switching web extension for Safari I like the tab-switching behaviour in Chrome/Firefox and wanted Safari to have something similar. Another wish of mine was for it to be a web extension that feels native to the browser vs an app extension that looks out of place. I posted a while back on HN to see if other people feel the same and the response was very positive : https://ift.tt/qoPE1x2 Say hello to TapTab : https://ift.tt/AoqcSMY... TapTab feels right at home in Safari and is loaded with features to improve how you interact with tabs. You no longer have to miss the native tab-switching functionality that you love in Chrome/Firefox. I launched the app a few days ago, and the response has been great. Some of the features that users have been loving : - Keep your hands at the keyboard: navigate all tabs without your hands leaving the keyboard. - Fuzzy Search: Search through your tab titles and URLs at lightning speed. - Switch to previous tab: Comes with a handy shortcut to go back to the previous tab. Finally! - Dark Mode: The extension feels right at home in Safari. - Multi-Window support - Pin/Mute/Close tabs right from the extension. The app is written in ReactJS (apart from the very minuscule bit of Swift you have to write for using it as an extension in Safari) and uses Tailwind for design. If you are one of the dozen people like me who use Safari, let me know how you find it. I would love to hear if there are any features that would make it a better fit for you. I have a few things on my radar gathered from talking to users like an iPad version, custom shortcuts, etc. If you find the extension useful I would love it if you vote for it on Product Hunt to get this in front of a few more eyeballs : https://ift.tt/duzOh60 Thank you! https://www.taptab.dev December 24, 2022 at 06:35AM

Show HN: Box4D – 4D physics demo using Rust and wgpu This is a little physics toy I've been working on off and on for a while. I originally planned on making a more fully featured game of some sort (I suppose I still may some day), but it turns out that writing interesting graphics and physics algorithms is more compelling than the hard work of polishing an actual product. Who knew? While there are plenty of good guides for 2D and 3D graphics and physics, there's not much out there for 4D. In hopes of alleviating that, the code here is arranged such that the commits are more or less a step-by-step guide, with comments for the interesting or tricky parts. While I don't think I came close to the simplicity or clarity of Box2D Lite, I hope it can serve as a useful example to anyone interested in 4D rendering and physics. https://ift.tt/Sc7MDgf December 24, 2022 at 12:00AM

Show HN: Metriport – Open-source universal API for health data https://ift.tt/8ueYyCl

Show HN: Metriport – Open-source universal API for health data Hey HN, we’re Colin and Dima, founders of Metriport ( https://metriport.com/ ). We help digital health companies access and manage user health and medical data, through an open-source and universal API. Today we're launching our open-source Health Devices API, which allows companies to gain access to their users’ health data from various wearables, RPM devices, and mHealth apps. You can check out the public Github repo here: https://ift.tt/NojtkDb For developers in the health data space, building integrations to various data sources is a huge pain, as it means wrangling different data formats, gaining access to the APIs in the first place, and ultimately spending precious developer resources building out data pipelines. We solve this pain for you through our open-source API, which is quick and easy to get started with (see: https://ift.tt/ve0NQC9... ). Out of the box, our Health Devices API supports integrations with Fitbit, Oura, Whoop, Withings, and Cronometer. We plan to add many more, including Garmin, Apple Health, and Google Fit in the near term. We work closely with our customers, so if there’s an integration you need, we’re more than happy to build it into our API. Because we’re open-source, you can also fork our code and build your own custom integrations. Getting started is simple. To start getting data from your users: 1) Create a developer account and generate an API key: https://ift.tt/3iu1FeA 2) Set up our client on your server and initialize it with your API key: https://ift.tt/ve0NQC9... 3) Link the Metriport Connect widget into your app. This pre-built widget makes it easy for your users to connect all their data sources into your application. Now you’re ready to start accessing your users’ health data from their sources they’ve connected. We also offer a hosted SaaS solution with usage-based pricing, with no minimum platform fees. We believe this will open doors to a wide range of early stage companies and help drive innovation in the digital health industry. While we’re excited to be launching this product today and be the first open-source Health Devices API of its kind, we’re also really looking forward to sharing our Medical API with you in the coming months. You can find out more about that here: https://ift.tt/Gg90Jy3 We can’t wait to see how this API is used and what it helps companies develop. Please don’t hesitate to reach out if you have any questions, and happy developing! https://ift.tt/NojtkDb December 23, 2022 at 03:39AM

Show HN: Fully offline, open-source alternative to Scribe for Firefox I had to do a bit of web-workflow documentation and found the process of gathering screenshots, placing them correctly into a document, and creating captions extremely tiring. I figured it’ll be easy to automate and also a great opportunity to get to know the Browser API, and here we are with the first release of the extension. It’s extremely easy to use but barebones which I plan to change in the near future, so any feedback will be appreciated. I want to keep the docs generation process completely offline to avoid dealing with server costs and GDPR stuff which poses a lot of challenges when planning more advanced features like image editing. It’s available only for Firefox because of Firefox’s great Browser API support, which Chromium currently lacks. Also, there’s a tool like this already available, called Scribe but it requires an account and also is not available for Firefox for some reason. Hope you’ll like it! https://ift.tt/E5ar1jy December 23, 2022 at 12:50AM

Show HN: How to use ChatGPT+ARKit to script experiences with natural language Video demonstration: https://youtu.be/bJFa5HOmhl4 I created a demo involving ChatGPT, OpenAI's Whisper running on-device for speech-to-text (because why not?), and ARKit. By defining a custom JavaScript environment with JavaScriptCore and describing it to ChatGPT, I was able to get it to produce functioning scripts that instantiate and manipulate 3D objects. Sketchfab is used to import 3D assets on the fly. Google Poly had a much better catalog of assets for this sort of thing but sadly, it's no longer available. The README.md describes how it all works but the gist of it is that user prompts are wrapped in a larger prompt that describes the environment (i.e., which functions are available to use and how they work) and constraints. The code is then executed directly. Assets for objects are fetched as needed by searching Sketchfab. https://ift.tt/YeCjrEn December 21, 2022 at 11:51PM

Show HN: Death by AI https://ift.tt/okTu9a5

Show HN: Death by AI I recently created a simple but efficient tool to help document writers generate a list of acronyms and definitions. Here comes chatGPT. At home, it’s all fun and games until I realize this thing might be able to do exactly what my “dumb” website does: "Give me the list of acronyms used in the previous text and their definitions"... It had a good-looking answer. Of course... At first I was bummed, but quickly realized that even though the output looked neat, it was also not reliable (missing some acronyms, adding some that were not in the original text, albeit related to it). Anyway, the next day I stumbled upon https://ift.tt/yptdzhR and the two things collided in my head: other people probably feel like AI is going to "kill" them or their product too. Why not make a list of these things? A shameless clone later (it's open source ) https://deathbyai.com was born. I was initially going for a more serious tone, but it soon felt impossible to give a fair story for each item in ~5 lines, so I went for something lighter and, hopefully, more fun. This is neither an attempt to criticize AI nor one to bury its "victims." On the contrary, I hope this page can highlight the potential of AI while showing that the "old ways" can still be relevant. Hope you like it. Feedback and contributions are welcome! https://deathbyai.com December 20, 2022 at 10:47PM

Show HN: A vichan variant that ChatGPT helped me host https://ift.tt/Wb1uIFy

Show HN: A vichan variant that ChatGPT helped me host I recently set up a website hosting vichan [0] with nginx, and named it "h2ochan", inspired by the chaotic (yet moderated!) nature of imageboards like 4chan and 2chan. Plus, I love having a liter of water within arm's reach at all times. In the future, I have some plans for threading and posts that will further emphasize the "water" theme and encourage community engagement. In the past, I had tried setting up vichan a few times, but I was overwhelmed by the many technical tasks involved, such as using a remote terminal, working with MySQL databases, configuring nginx, setting file permissions and owners, and using Emacs (or trying to avoid clunky local file edits and FTP). However, I recently discovered chatGPT and have found it very helpful in assisting me with various technical issues. I began by asking for help setting up a public PHP forum, saying that I was a gamedev with some experience in Unity and C#, but not familiar with web development. chatGPT recommended that I look into ASP.NET [1] (which is similar to C#) and gave me some specific recommendations for webhosts and domain registrars. Based on these recommendations, I was able to get a Shared Windows Host [1] up and running, with my nginx [3] page visible after visiting the proper IP address. During the vichan installation process, there is a config-help screen that shows red and yellow lights, to show stuff like if vichan is missing permissions, the SQL database is misconfigured, etc. Initially, this screen showed about three errors and five warnings, mostly related to vichan's inability to read or write certain files. ChatGPT was very helpful in troubleshooting these issues, whether I copy-pasted error messages or described the problems in my own words. It helped me with tasks such as using `chmod`, `chroot`, and `grep`, as well as with fixing HTTP status codes such as 403 Forbidden, 404 Not Found, and 500 Internal Server Error [2]. ChatGPT also helped me locate log files and fix other issues, and eventually all of the warnings were resolved. Emacs was also very helpful during the setup, with chatGPT assisting with emacs commands (I have a double-sided Sheet of them somewhere...) Although I am still learning basic hotkeys, I am able to Save, Undo, and Quit with confidence, and I have almost memorized the Page Up/Down keys. I was initially drawn to Emacs because I saw a page about hotkeys for capitalizing, lowercasing, and uppercasing words years ago, but never sticking with it. Now using it more, my thoughts still being "My smartphone can't even Delete (forward) or Undo! Modifying whole WORDS like this is incredible!" Please go look at h2ochan, and Drink Water! [0] https://ift.tt/VelsgCh [1] I did have to switch from a Shared/managed ASP.NET to a Dedicated Linux Host, since remote SSH was not supported for Windows, only Linux [2] I forgot two of these error codes, so I asked chatGPT to remind me of ones I might have encountered during setup. chatGPT also revised my initial post (making sure chatGPT got a [] citation, no matter how confusing!) which I revised once more before posting. [3] Windows + nginx, huh? I may be mis-remembering this bit, but there was certainly a point of realizing "I need Admin access so I can edit Permissions..." or something, and that Windows without SSH was wholly insufficient for vichan [-] chatGPT was occasionally a bit outdated, which led to missing packages, non-existent paths, and imperfect configurations. However, it seemed happy to accept corrections, such as when I wanted to show line numbers in PHP files in Emacs, but my init.el file already had a setting to show line numbers for all programming languages, and I didn't have php-mode installed. Instead, I needed to use phps-mode. [-] The website favicon is a Koreisha mark, hue-shifted to the Blues. It's used in Japan to signify elderly drivers, and used Abroad by Car Enthusiasts. I love the Half-Teardrops in contrasting Bright and Subtle Blue. https://www.h2ochan.org December 20, 2022 at 10:14AM

Upcoming Capacity Indicators

Upcoming Capacity Indicators
By Christopher Ward

Next Generation Customer Information displays will show capacity indicators: One figure means there are many seats available. Two figures indicates that there are likely a few empty seats available. Three figures tell you that there’s likely only standing room available.

The SFMTA continues expanding trip planning and accessibility features and improving Muni predictions. This is part of the ongoing Next Generation Customer Information System (CIS) project. One of the newest features is a capacity indicator.

A capacity indicator helps customers understand how much space is available on vehicles. Customers can see the indicator on our Next Generation displays in the bus shelters and on train platforms. Customers may use this information to make travel choices. For example, customers can choose to wait for a less full vehicle or take an alternative route.

As of November 2022, Muni vehicles equipped with automatic onboard passenger counters send capacity information to our Next Generation CIS. This information is now shown symbolically with stick figures. One figure means there are many seats available. Two figures indicates that there are likely a few empty seats available. Three figures tell you that there’s likely only standing room available.

Customers should always yield the priority seating area for people with disabilities, older adults, and pregnant persons.

We’re excited to finally bring these features to our customers and build a system that will help make Muni travel even more efficient, reliable and enjoyable.

Show HN: The easiest way to run a brainstorm, supercharged with A.I Hello friends! We've been working hard on building Mimosa, and would love for you to try it! No signups required. Facilitating brainstorming sessions can be a challenging and time-consuming task. It's difficult to keep everyone on agenda, engaged, and contributing. So we've built Mimosa to be the easiest way to facilitate a brainstorming session. Imagine if a "digital whiteboard" and a "trello board" had a baby, but built with all the best practices of professional facilitation. With Mimosa, you can minimize bias by allowing team members to contribute anonymously before revealing their ideas. This ensures that everyone has a fair chance to share their thoughts and ideas without fear of judgment. Once the brainstorming session is complete, you can easily view and export the final results. This allows you to keep track of a meeting's effectiveness and share it with stakeholders. But the real game-changer is our AI Brainstorming features and it's ability to turn your 1x team into a 10x team. It help generates and collaborates with you in your brainstorming session to help you come up with more and better ideas. We're both scared and excited to hear all your thoughts, HN! :) Please do let us know any features or improvements you think we should make to help you in your meetings. https://mimosa.so/ December 17, 2022 at 12:11AM

Show HN: Natural language Twitter search using Codex https://ift.tt/P5spM2a

Show HN: Natural language Twitter search using Codex We built a structured search engine for Twitter called Bird SQL, available at https://ift.tt/g1p29Gd . Our search interface uses OpenAI Codex to translate natural language to SQL. Our backend then verifies the SQL, executes it, and displays the results on the web app. This makes large structured datasets like a scrape of Twitter easy for anyone to explore. As background, while working on text-to-SQL as a general problem, we came to believe one of its most powerful applications is as a search tool because: - SQL is hard to write by hand and prone to errors - It allows you to iterate quickly if you’re exploring a new dataset - A lot of contextual information that you’d normally have to internalize (e.g. your data’s schema) can be automatically generated and offloaded to the language model Using large language models (LLMs) like Codex to write the SQL for you means you don’t have to worry about the nitty gritty language details, but still benefit from the power of a language like SQL. Also, after seeing the results of the query, you can inspect (and if necessary, change) the SQL. The lack of this sort of explainability of the query result is one of the more notorious challenges of returning the output of an LLM directly to the user. Additionally, using LLMs in this way makes these kinds of queries over structured data accessible to people who know little or no SQL. While Bird SQL shares significant infrastructure with our more general LLM-powered search engine over unstructured data (Ask Perplexity - https://perplexity.ai[1] ), the two approaches and their respective challenges are quite different. For example, the type of models are different (GPT3.5 vs Codex), obviously the model prompts have different structure, and how to verify model output when its text vs when its code is different. We are currently exploring ways to combine the two approaches, such as using the results of retrieving information from a structured source (as in Bird SQL) as one of the inputs for the LLM to interpret or summarize (as in Ask Perplexity).

Show HN: Readwise Reader, an all-in-one reading app Hey HN, cofounder of Readwise here. We've been working on this cross-platform reader app for about 2 years, excited to finally share it in public beta. Probably the most notable thing that makes Reader unique is that it supports almost any content type you could want to save/read/highlight: * web pages * emails/newsletters * PDFs * ePubs * twitter threads * youtube videos (with transcripts) * RSS feeds With all of your knowledge content in one place, we built powerful reading and highlighting, as well as a bunch of novel triage/organization features, so you can actually consume & stay on top of that content! There are also a lot of advanced features too, such as text-to-speech, GPT3 questions/summaries, super powerful highlighting (that includes markup and images), complex filtering/search (with our own query language), sleek mobile triage UI, keyboard shortcuts for reading/everything, integrations with note-taking apps, a browser extension for both saving pages and highlighting them, and much more. If anyone's interested in more product details, as well as our business model, etc, we wrote a detailed launch post: https://ift.tt/HESizsg... Predicting a common question: Reader is part of the Readwise subscription pricing right now in beta -- there's a 30 day free trial and then it's paid at ~$8usd/month. We also promise to not raise this price for existing subscribers. Reader is also fairly technically interesting -- our iOS, Android and webapp all work fully offline and sync your reading data/progress with eachother. Our search on web is built with wasm sqlite. We have a fairly intense pipeline for cleaning web articles (removing ads/styling). We share lot of modules around syncing/highlighting across all platforms, etc... Happy to answer any questions :) https://ift.tt/pM2wkzL December 16, 2022 at 03:14AM

A Brief History of the T Third Part 2: 1980s-2023

A Brief History of the T Third Part 2: 1980s-2023
By Jeremy Menzies

Beginning in January 2023 full service on the new T Third extension 2023 will run from Sunnydale to Chinatown every day. In this two-part blog series, we will look back at some of the history of the T Third Street line. Part 1, published last month goes through the first 100+ years. In Part 2, we look at the recent history of the T Third and Central Subway projects from the 1980s to today. 

The Call for Better Transit: 1980s-90s 

In the decades following World War II, the neighborhoods along the southern end of 3rd Street became more economically depressed and transit service declined.  Residents felt cut off from the rest of the city as bus service did not meet their needs. 

People boarding a 15 Route bus on 3rd Street near Market in 1983. Bus service on the 15 provided critical north-south service through the City’s busiest areas. 

In the late 1980s, the city was looking to revitalize the Mission Bay, Dogpatch, and Bayview and reliable transit was critical to this goal. Early outreach and research resulted in the 1993 Bayshore Transit Study. This initial plan solicited community input on several possible solutions on how to improve transit to these neighborhoods. Two years later in 1995, the Four Corridor Plan built upon the Bayshore Transit Study and elevated 3rd street as the top priority for San Francisco’s long-range transit plan. It was clear that residents, particularly in Bayview, wanted rail service to return to 3rd Street. 

T Third Phase 1: 1990s-2007 

These reports and outreach formed the backbone of the Third Street Light Rail Project, which would be built in two initial Phases. Phase 1 involved extending Muni Metro service from 4th and King to Bayshore Boulevard along 3rd Street. Phase 2 would focus on the 4th and Stockton corridors to extend the service into Chinatown and possibly North Beach. 

By the end of the ‘90s, funding was coming in to make Phase 1 a reality. Early plans for the T also included a new rail maintenance facility, Muni Metro East, as well as a turnback loop in Mission Bay and a direct connection to the Bayshore Caltrain Station. Due to various factors during preconstruction planning, the Mission Bay Loop and Bayshore Caltrain connection were dropped from the T Line plan. 

A groundbreaking ceremony for T Third construction was held on May 28, 2002 at the 4th and King Caltrain Station.  

Construction of 5.1 miles of new tracks, overhead power lines, lighting, stations, and a variety of other improvements took five years to complete. On January 13, 2007, free weekend shuttle service commenced on the new line and full weekday service started on April 7. Just one year later in 2008, the Muni Metro East rail yard opened, boosting Muni’s ability to serve the new line. For the first time in 50 years, rail service returned to the eastern waterfront. 

View north along 3rd Street at Jamestown Avenue during construction in 2004. 

T Third Phase 2: Central Subway 

Planning and outreach for Phase 2 of the T Line had already begun when the line opened in 2007. The Central Subway Project was created to address the transit needs of Chinatown, Union Square and South of Market. Construction would extend the T nearly two miles and build the first new subway in the city since the 1970s.

This 2016 photo, taken inside the excavation for Chinatown Station shows the massive scale of the Central Subway Project. 

Early proposals showed the Central Subway traveling north on 3rd Street and along Geary where it would turn up Stockton to end in Chinatown. Going south, the line would branch and exit the tunnel on 4th Street. The challenges of construction along 3rd and at Market Street resulted in a plan to run the line on 4th and Stockton streets. It was also decided to tunnel underneath the Market Street Subway/BART tunnels using special tunnel boring machines instead of more conventional construction methods. 

The official groundbreaking ceremony took place on February 9, 2010. The arduous process of building a subway with four stations through San Francisco’s densest neighborhoods began soon after. Despite an intensive construction period with project delays and cost increases, the Central Subway opened for service on November 19, 2022.  

Opening day of the Central Subway on November 19, 2022. Thousands of people came out to see and ride in the long-awaited subway. 

Over 30 years in the making, the T Third line follows in the footsteps of the first horsecars that ran over 160 years ago. However, this is not the end of the line for the T. Planning is already underway on the T Third Phase 3 extension. Aimed at expanding service beyond 3rd Street, this extension will mark yet another chapter in San Francisco’s transportation history.

Show HN: AI Avatar Image Generator Based on Other AI Images An AI Avatar image generator that creates images of you based on other AI created images. The popularity of the recent AI Avatar image generator apps sparked some interest of mine in the area. After playing around with a few AI Avatar image generators, some of which generate pictures of you based on pictures you upload and prompts you write, I thought, wouldn't it be much easier, instead of writing out prompts, to just select another image which you want your generated image to be based on. The image the user selects is actually another AI generated image, so we know the prompt used to generate it. So prompt writing is abstracted away from the user, and instead they can search for images and click on ones they like. Backend of the application currently uses Astria AI for the image model training and generation, and uses the Lexica API for getting lists of AI generated images and their prompts. https://ift.tt/w9fLgP0 December 15, 2022 at 08:19PM

Central Subway Brings More Art to Union Square

Central Subway Brings More Art to Union Square
By Enrique Aguilar

Main entrance to Union Square/Market Street Station during special weekend service 

The Union Square/Market Street Station is centered in the heart of the Union Square neighborhood, known for world-class shopping and notable art galleries. With the opening of the Central Subway, a new public art collection arrived, with color schemes complementing the station’s modern architectural design. Collaborations between artists reign at this station, allowing a blend of different artistic concepts. 

• Erwin Redl titled his piece Lucy in the Sky. It is an illuminated installation comprised of hundreds of translucent 10 x 10 inch light panels, each containing an array of color LEDs. A diamond-shaped pattern is formed by suspended light panels along the entire length of the concourse level corridor’s ceiling. They are computer programmed to slowly change color and display simple patterns, creating an immersive and kaleidoscopic experience.  

• Jim Campbell and Werner Klotz created a site-specific stainless-steel sculpture called Silent Stream, located on the station’s platform level. Comprised of highly polished steel disks, the overhead installation loops its way through the struts along the length of the platform and reflects the passengers and trains passing below.  

• Amanda Hughen and Jennifer Starkweather integrated a design into the glass deck and the front faces of the glass elevator enclosures. Titled Convergence: Commute Patterns, the artwork is based on the dynamic and diverse pathways, commute patterns and arterial structures above and below the streets of the Bay Area. The artwork’s visual impact on the station’s exterior alternates from being subtle during the day to backlit at night.  

Watch an interview video with comments from Amanda Hughen, Jennifer Starkweather, Erwin Redel, Jim Campbell and Werner Klotz. Get to know the artists and learn directly from them about their work at the new Union Square/Market Street Station. A special thank you to the San Francisco Arts Commission for making public art possible at the four new stations. 

Special Weekend Service started on Nov. 19 and will last through the end of the year, Saturdays and Sundays from 8 a.m. to midnight. Full revenue service will begin January 7, Monday through Friday, 6 a.m. to midnight and Saturdays and Sundays, 8 a.m. to midnight.

New T Third Route in Central Subway Starting January 7

New T Third Route in Central Subway Starting January 7
By Mariana Maguire

New T Third service via Central Subway starts January 7 with service between Sunnydale and Chinatown-Rose Pak Station.

On Saturday, January 7, the T Third starts its historic new route, providing a direct Metro connection between Sunnydale and Chinatown-Rose Pak Station. Service runs Mondays through Fridays, 6 a.m. to midnight. every 10 minutes and Saturdays and Sundays, 8 a.m. to midnight every 12 minutes. The new T Third line vastly improves transportation to and from some of San Francisco’s most densely populated areas and major shopping corridors, expanding transit options and new connections.

The new T Third route will travel north to the new Central Subway from 4th & King platform. It will no longer turn onto King Street or run along the Embarcadero and the Market Street subway. Also, the K Ingleside will now travel between Balboa Park and Embarcadero Station.

New Connections

Customers traveling to stops along the Embarcadero, the baseball stadium at 2nd and King streets should transfer to the N Judah. Customers should transfer at Powell Station to Union Square/Market Street Station for the T Third going to Sunnydale.

To transfer to the new T Third at Union Square/Market Street Station from the J Church, K Ingleside, M Ocean View, N Judah or BART at Powell Station, you can connect entirely underground. From the Powell Station platforms, take the elevator or follow signs to concourse level, then follow signs to Union Square/Market Street Station.  

Customers on the T Third connecting to other Muni Metro routes or BART should follow signs on the Union Square/Market Street Station platform toward Stockton/Ellis streets.

Navigating the Union Square/Market Street Station

The new Central Subway stations have many new features, including long escalators – the longest in the United States west of the Mississippi – and two glass elevators at every level for more accessibility.

Customers who need to use the elevators to the platform should bypass the fare gates near the street entrances at Union Square/Market Street Station. Instead, use the fare gates in the center of the concourse.

MuniMobile and Lifeline customers may use any fare gate at the Union Square/Market Street Station.

Special Chase Center Event Service

During events at Chase Center, the SFMTA will run special event service about every 10 minutes in addition to normal T Third service. The additional special event trains – with “S Chase Center” head signs – will serve all stops between Chinatown-Rose Pak Station and UCSF/Chase Center. From end to end the ride takes only 20 minutes. Best of all, your event ticket is your Muni fare. No additional Muni fare needed!

Customers traveling past Chase Center during this special event service should check train head signs and only board “T Third” trains for a one-seat ride to their destination.

We know new T Third service in the new Central Subway is a big change that will take time to get used to. We’re here to help! Stay tuned for helpful wayfinding guidance and orientations, and check out our Frequently Asked Questions for helpful commuting tips.

Show HN: We scaled Git to support 1 TB repos https://ift.tt/2lLXJxH

Show HN: We scaled Git to support 1 TB repos I’ve been in the MLOps space for ~10 years, and data is still the hardest unsolved open problem. Code is versioned using Git, data is stored somewhere else, and context often lives in a 3rd location like Slack or GDocs. This is why we built XetHub, a platform that enables teams to treat data like code, using Git. Unlike Git LFS, we don’t just store the files. We use content-defined chunking and Merkle Trees to dedupe against everything in history. This allows small changes in large files to be stored compactly. Read more here: https://ift.tt/eusXP3K Today, XetHub works for 1 TB repositories, and we plan to scale to 100 TB in the next year. Our implementation is in Rust (client & cache + storage) and our web application is written in Go. XetHub includes a GitHub-like web interface that provides automatic CSV summaries and allows custom visualizations using Vega. Even at 1 TB, we know downloading an entire repository is painful, so we built git-xet mount - which, in seconds, provides a user-mode filesystem view over the repo. XetHub is available today (Linux & Mac today, Windows coming soon) and we would love your feedback!

Show HN: Bugbusters.ai automated bugfixing using gpt-3 https://ift.tt/fmX0cpR

Show HN: Bugbusters.ai automated bugfixing using gpt-3 Hi everyone on HackerNews, We are just launching Bugbusters. Bugbusters is a GitHub-Bot that writes bugfixes for errors detected by application monitoring software like sentry. It examines an error's monitoring data, such as stack traces, in combination with the source code and git commit history to generate a potential fix. The bugfix will be submitted via a Pull Request that will also include details on the determined cause of the initial error and approach taken to fix it. You can simply create a GitHub Issue containing a link to the error in sentry and assign it to the Bugbusters-Bot. In cases where the bot is unable to generate a solution, it assists a programmer in finding a fix by providing information and steps that could lead to a resolution. This may involve providing a list of potential error causes, online research results such as stack-overflow posts, as well as code changes (commits) that may have caused an error. While we are currently focused on automated bug fixing, there are lots of other interesting features that we want to incorporate in the future, such as: Avoiding the reoccurrence of a bug by generating unit tests or recommending steps such as a refactoring to avoid them in the future. Integration into IDEs/terminals/std-err, which would allow developers to overcome errors during coding time much faster. A programmer could also be informed that their code has a certain error-proneness or that they are working on a critical section that has been causing errors in the past. Improving PR-Reviews by tracking critical code sections and highlighting them during reviews. This would allow developers to consider previously caused bugs and improve the quality of their code. Overall, we believe that Bugbusters has the potential to greatly improve the efficiency and effectiveness of bug fixing. Let us know what you think! https://ift.tt/IDl0roE December 13, 2022 at 07:28AM

My friend Francois-Guillaume made Image Charts in 2015 to replace Google Image Charts for a project since it was deprecated. Since then we’ve been adding features and getting it integrated with Zapier and Make to make it easy to build good-looking charts automatically. Each chart has a custom URL and HTML code so it’s easy to embed. And you can build progress bars, gradients, and really any kind of chart with it (bar, line, radar, scatter, you name it). We have a gallery of over 30 charts and counting.

Riders are Feeling the Difference on Geary

The results are in: the Geary Rapid Project has delivered a faster, more reliable bus trip and a safer street, according to the SFMTA’s recently published evaluation report for the project.  

A faster, more reliable bus ride 

One out of every ten passengers stepping onto a Muni vehicle will ride on Geary Blvd., which makes reducing travel time on the corridor a key piece of improving transit in the city. The transit lanes installed as part of the Geary Rapid Project protect buses from traffic congestion, while smarter traffic signals allow buses to get green lights more often. Similar transit upgrades have been made across the city as part of the Muni Forward program, making your next San Francisco destination closer than ever. 

Transit travel time improved after the quick-build phase of the Geary Rapid Project in late 2018 and early 2019, and again after the full project was completed in 2021 — with savings as great as 18%. Westbound travel times generally improved the most — up to 3.6 minutes during the PM peak — providing a daily 38R Geary Rapid rider 18 hours of savings per year. Although the biggest time savings were seen during commute hours, with 36,000 riders traveling on Geary around the clock each day, even smaller gains outside of peak hours adds up to major travel time savings for all Geary riders combined.  Travel time reliability also improved up to 37%, which means that the time spent waiting for the next bus is more consistent. 

A safer street  

Reducing Muni-involved collisions is critical to protect our passengers and operators. It also keeps Muni service running smoothly; even non-injury collisions cause buses to be taken out of service. Adding dedicated transit lanes on Geary Boulevard has substantially reduced the rate of Muni-involved collisions on the corridor. The collision rate of 38/38R buses decreased by two-thirds and is now about half that of the current citywide Muni bus collision rate. Several years of data will be necessary to fully evaluate the project’s impacts on reducing traffic collisions in general. But one promising indicator is that there was a 70-80% reduction in vehicles traveling over 40 mph (more than 5 mph over the speed limit). A suite of improvements to calm the “expressway” section of the corridor, including a reduction in general-purpose travel lanes to two per direction, new crosswalks, narrower travel lanes and bulb-outs (sidewalk extensions) were implemented to encourage people driving to slow down.

Keeping transit lanes clear 

One of the final portions of the project was painting the transit lanes red. This “red carpet” treatment makes it easier for drivers to know where they’re allowed to drive. When we make transit lanes extra clear with red paint, drivers are less likely to get a citation for unintentionally driving in a transit lane. Previous SFMTA studies showed that the number of private vehicles illegally using transit lanes declines about 50% when the lanes are painted red. Sure enough, the number of vehicles entering the lanes on Geary dropped by 47% from 2019 to 2022, even as traffic congestion returned after COVID restrictions eased (vehicles driving legally in the transit lane to turn right or access curbside parking or driveways were not included). 

The full evaluation report is available on the SFMTA website and covers several additional metrics, including street space allocation, Muni customer experience and parking availability. 

The success of the Geary Rapid Project has informed the final design for the second phase of upgrades, the Geary Boulevard Improvement Project, which proposes to expand these improvements west into the Richmond District.
