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/xEZGCcY December 31, 2022 at 04:13PM

Ability to skip to a position in playlist from beginning. 3. Request any new channel you would like to have a reverse playlist for ! Usage eg: - Using the above you can skip to say 100th video from begining in a channel (e.g CaseeyNeistat Vlog) and keep watching on youtube app (without going back to bingethetube.com). - Come back next day and resume watching from say video 120 without a lot of scrolling Useful if you like to follow a creators youtube journey or old Vlogs ! https://ift.tt/PfnHukB December 30, 2022 at 04:58PM

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/ZgF7Dfp Interested in your feedback! https://ift.tt/4ARgEin December 28, 2022 at 06:14AM

Show HN: I built a simple CLI helper integrating with GPT-3 https://ift.tt/hZB5PTv

Show HN: I built a simple CLI helper integrating with GPT-3 Hi all! I don’t think CHATGPT has gone unnoticed by anyone here on Hackernews. I’ve myself played around a bit with it, but felt it was annoying to always have to log into their GUI to ask the questions. To scratch my own itch and at the same time learn more about how to write my own command line interface, I created 'askai'. 'askai' is a simple CLI integration with OpenAI’s GPT3 models. I’ve primarily used it to get quick answers to technical questions, like: > askai "How to mock user input when writing a Python pytest test?" > askai "How do I remove a conda environment?" As I've found it quite helpful, I decided to spend some time to package it in a nicer way to share it with all of you. I've also uploaded it to PyPI to simplify the installation process. 'askai' enables you to: * Ask questions and get the answers straight into your terminal * Configure which model and model parameters you want to use * Overwrite saved configurations when you ask questions Currently, it only supports OpenAI’s models, but my plan is to integrate more endpoints as soon as new capable NLP endpoints are popping up. I hope some of you find it useful :) https://ift.tt/UbrwgfH December 27, 2022 at 11:29PM

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/Hqo2ZrS December 27, 2022 at 05:27AM

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.

The idea is simple: automate creating promo quality videos that include screen recordings as much as possible Currently it makes cursor movement smooth, zooms in on clicks, adds background and frame around recorded window and adds cinematic motion blur. I plan to add selfie camera support, full text slides and multi-clip recordings. Works only on macOS.

Show HN: Natural language Twitter search using Codex https://ift.tt/JT5S9NB

Show HN: Natural language Twitter search using Codex We built a structured search engine for Twitter called Bird SQL, available at https://ift.tt/oEpbfVj . 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). We would love to hear your questions, suggestions, and feedback! [1] https://ift.tt/2rk4dop https://ift.tt/GrmnBlx December 16, 2022 at 05:12AM

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/jY2uAsi... 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/gv8KzE4 December 16, 2022 at 04:44AM

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.

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: Onin – E2EE calendar and chat app https://ift.tt/0RgW8Fh

Show HN: Onin – E2EE calendar and chat app Hey HN! Ryan here (co-founder of YC-backed Muzz). I’m now building Onin, an end-to-end encrypted calendar and chat app that makes organising your personal and social life simple and secure. I’ve been building technology businesses for 10+ years and have witnessed the reoccurring problem that digital calendars were built for companies, not people. They feel cold, transactional, and anti-social — not the thing of dreams for planning your personal life. They also lack the security we now come to expect from consumer products. Onin is the first calendar to be fully E2EE, protecting not just your events, but your messages and even your profile. Unlike existing E2EE calendars, you cannot share Onin events to others without the protection of E2EE. When you consider how much personal information your calendar stores about you and your loved ones’ lives, we think this is essential. With such a focus on security and privacy, it’s only fitting that we host our Privacy Policy and Terms of Service on GitHub to be as transparent as possible with our users. But beyond security, how is Onin so different? Our research found that 84% of events are planned entirely in chats. But our calendars are disconnected from these conversations, leaving our schedules constantly out of sync. To fix this, we’ve collapsed and combined calendar and chat into one secure app, eliminating the fragmentation between events and the conversations that form them. Some of our unique features include: - Calendar keyboard: Access your calendar from within the chat - Event chats: Creating a new event generates a dedicated chat - Just phone numbers: No more searching for your friend’s email - End-to-end encryption: All our events and chats are E2EE, even your profile too Onin is proudly the world’s most private calendar by default: - End-to-end encrypted events, profiles, and messages - Two-Factor Authentication required - Chat without revealing your phone number - (Coming soon) Your unique link to invite people, no need to share your number We’re exactly 4 weeks away from launching the public beta to our waitlist community.

Show HN: We scaled Git to support 1 TB repos https://ift.tt/x6cyJzf

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/TEInZtM 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/FM6bS9f

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/OTWc0x9 December 13, 2022 at 08:58AM

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.

Show HN: Panoptisch – A recursive dependency scanner for Python projects Hello all, Very excited to share this project with you all! Panoptisch scans your Python file or module to find it's imports (aka dependencies) and recursively does so for all dependencies and sub-dependencies. It then generates a dependency tree in JSON for you to parse and enforce import policies. Supply chain attacks are no joke, and this is one way to transparently analyze your dependencies to see if any malicious imports are taking place. For example, your yaml parser, nor it's sub-dependencies should import socket, or sys. Panoptisch is in early stages, with known limitations (for now). I welcome feedback, testing and contributions. Also, happy to answer any questions! https://ift.tt/ZkCsMqb December 10, 2022 at 04:45AM

Riders are Feeling the Difference on Geary

Riders are Feeling the Difference on Geary
By

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. 

Comparison graph of 40 mph travel speeds before and after the Geary Rapid Project. 

 

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.  

A photo is worth a thousand words to show the improvements made on Geary Boulevard. These birds-eye shots provide representative examples of the street design on Geary before (August 2018) and after implementation (February 2022) of the Geary Rapid Project.

Shared Spaces are Here to Stay. Permit Renewals are Due January 15, 2023.

Shared Spaces are Here to Stay. Permit Renewals are Due January 15, 2023.
By Anne Yalon

Shared Spaces, amongst many other benefits, allows our residents and families to enjoy safe and social outdoor dining. Seen here are the the owners of Tio Chilo’s Grill and their children in the restaurant’s parklet on 24th Street in the Mission. 

San Francisco’s popular Shared Spaces program allows merchants, restaurants and arts and culture organizations to use the curbside, sidewalk and other public spaces to conduct local business activities and stay afloat. What emerged as an economic lifeline during the pandemic is making San Francisco’s streets more energized, engaged and activated.

Many of the Shared Spaces parklets have become central gathering places for the local community. “Our parklet makes me feel like when I go to Mexico, where outdoor seating is everywhere. People end up joining their friends in our parklet. It is a space for our customers and our community," said Liz Vazquez, owner of Tio Chilos Grill. Ray Bair, owner of Cheese Plus, said, "My Shared Space has been a community gathering space. It's an ideal location because we are on a corner. I go out to it every afternoon and see so many people from the neighborhood sitting and enjoying the space. It's so satisfying to see people using the space for what the Shared Spaces program was intended for."

Now, Shared Spaces is transitioning from an emergency initiative to a permanent program. In July 2021, the San Francisco Board of Supervisors unanimously passed legislation introduced by Mayor London Breed to make the Shared Spaces Program permanent. Permits from the pandemic-era Shared Spaces Program were extended to June 30, 2022 and then later to March 31, 2023. Parklet owners have until January 15, 2023 to renew their permits which, once approved, will go into effect on April 1, 2023.

The extension has allowed additional time for small businesses to make any necessary modifications to their shared spaces as they transition into a longer-term permit. Because many of the Shared Spaces were built very quickly, some of them need to be modified to meet the most up-to-date guidelines for safety and accessibility.

So far, 450 permit applications have been submitted for the long-term Shared Spaces program. San Francisco operators who want to keep their existing outdoor Shared Space beyond March 2023 need to renew their permits by January15, 2023. Permit holders wishing to end their existing Shared Space also need to notify Shared Spaces.

Parklet owners who are still deciding if a Shared Spaces permit will work for their business or need to modify their Shared Space to fit the city’s design guidelines can watch the 2-minute design guidelines videos. These videos explain how to make Shared Space safe and accessible for all. They focus on intersection safety and visibility, and emergency access for the fire department. Another video about disability access is in the works.

More information for parklet owners is available at these upcoming events:
