Show HN: ParallelGPT – Batch processing with ChatGPT on low-code spreadsheet UI We made ParallelGPT - a tool that lets you bulk process chatGPT on a spreadsheet UI instead of one-by-one conversation style. Hopefully this saves you time and hassle - especially if you want to build an operational process around it and want to collaborate your team. You can give it a quick spin on this live demo playground: https://ift.tt/tbYGo2q... I am the co-founder of Rowy( https://www.rowy.io ), an open-source low-code platform, and we built ParallelGPT as a fun showcase of what you can do with low-code. There are tons of exciting AI apps you can build with low-code, and we're always happy to chat about any ideas you have and assist on our Discord. https://ift.tt/6gVhyRw April 1, 2023 at 07:47AM

Show HN: Simply explain 20k concepts using GPT https://ift.tt/Gjp2kJg

Show HN: Simply explain 20k concepts using GPT Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even about, so this was a way to get the high level idea about random things that I wanted to know about. It also only uses the information in the GPT model at the moment, so obviously information can't be trusted completely and you should definitely double check any information you read here by Googling. I'm thinking of doing the Bing Chat approach for the next version and adding references, but don't have that yet Hopefully someone else finds this useful even if it's not perfect! https://ift.tt/mhdfNMe April 1, 2023 at 05:24AM

Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/oYO2GPM April 1, 2023 at 01:35AM

The Municipal Railway Planning Division & The First 5-Year Plan

The Municipal Railway Planning Division & The First 5-Year Plan
By Kelley Trahan

The San Francisco Municipal Railway 5-Year Plan, 1979-1984 was the first comprehensive service plan created by the first San Francisco Municipal Railway transportation planners. The plan introduced a grid system to provide more efficient crosstown service with better neighborhood connections that would improve access and increase ridership, moving away from Muni’s prior service design focused on trips to and from downtown. It also provided service standards, including coverage, capacity and stop spacing, many of which continue to inform Muni planning efforts today. The San Francisco Municipal Railway saw many changes at this time, including the opening of the Muni Metro, the conversion of some lines from diesel to electric trolley bus, a simplified fare structure and increased fares and historic streetcar service on Market Street. 

Prior to the mid-1970s, the San Francisco Municipal Railway’s service development was determined by a mix of privately-operated transit systems it had acquired, rather than one master transit plan. This changed when the federal government required the agency to submit a 5-year plan to be eligible for funding.  

The entire process began when President Lyndon B. Johnson signed the Urban Mass Transportation Act of 1964 into law in response to the nation’s long-term transportation investment needs. The new law provided grant and loan money to local transportation systems and created an oversight agency, the Urban Mass Transportation Administration (UMTA), which would be renamed the Federal Transit Administration (FTA) in 1991. The Metropolitan Transportation Commission (MTC) then was put together by the California State Legislature in 1970 and tasked with reviewing transportation grant applications submitted by agencies in the state. 

 

Urban Mass Transportation Act of 1964, Public Law 88-365, 78 STAT 302

An in-depth study of Muni was undertaken in 1974 by Wilbur Smith & Associates, a private consultant and author of the UMTA’s Characteristics of Urban Transportation Demand: A Handbook for Transportation Planners. The Municipal Railway Planning, Operations and Marketing (POM) Study was completed in 1977 and analyzed the Muni system and the travel needs of its riders and made recommendations for a 5-Year Plan. 

 A new in-house Muni Planning Division that had been created with UMTA funding in 1974 presented the POM Study at more than 70 community meetings, and after intense review and several revisions, The San Francisco Municipal Railway 5-Year Plan, 1979-1984 was drafted. 

Muni Planning Division Employees in Presidio Trolley Coach Yard, May 17, 1979

Since that first plan was written, transportation planning at the SFMTA has expanded to include capital projects, street design, bike lanes, paratransit, parking, historic streetcars and much more, while promoting safety, equity and sustainability. The SFMTA continues to publish an operating and service plan approximately every 10 years, now called the Short-Range Transit Plan (SRTP), which is based on the needs, goals and agency priorities to serve the people of San Francisco.

Show HN: Kaskada – modern, open-source event processing https://ift.tt/YwflTmW

Show HN: Kaskada – modern, open-source event processing We recently open-sourced Kaskada – an event-processing engine built on Rust and Apache Arrow. It features a high-level, declarative query language designed specifically for reasoning about events in bulk and in real time. Unlike SQL, an aggregation over events produces a timeline indicating the value at each point in time over the events that have occurred up to that point in time. The query language provides composable, expression oriented syntax, including the ability to nest aggregations. Due to the focus on events and temporal queries, it provides capabilities to shift events forward (not backward, to avoid "leaking" information about the future into past values), ticks that create new times (allowing you to observe the current value of an aggregation every day, for instance) and joins that operate "at the current time". Example query: # Purchases up to a point in time let purchases_now = count(purchase) # Shift that *forward* one day (so the value now is from 1 day ago) let purchases_yesterday = purchases_now | shift_by(days(1)) # Compute the difference (purchases since yesterday) in purchases_now - purchases_yesterday More on the history of Kaskada is available in this blog post https://ift.tt/CbBQXhf . More information on the project (and documentation) is available at https://kaskada.io . https://ift.tt/U1HNXqV March 31, 2023 at 01:27AM

Show HN: Mirrorful – A developer-first way to implement designs faster https://ift.tt/QFHGKuS

Show HN: Mirrorful – A developer-first way to implement designs faster Hey HN! Mirrorful ( https://ift.tt/x4HqhZ1 ) is an open-source developer framework that helps front-end engineers manage their design systems. We’ve been building Mirrorful with the open-source community ( https://ift.tt/0d3wVUW ) and wanted to share our beta with you. Check out our online demo to get the idea: https://ift.tt/FOtiYTa . Design systems can be thought of as the “building blocks of your app” which makes me think of Lego bricks. Mirrorful helps you manage your codebase’s Lego bricks and ensure that they are consistent across all of your apps and platforms. We saw as product engineers how hard it is to get code to match Figma mock ups. High-quality design is a competitive advantage, so getting your UI pixel perfect can matter a lot, but is time-consuming and tedious. When we worked for large public companies, we saw that good component libraries help, but engineers are often still dealing with tweaking small design decisions. There are a lot of inefficiencies. We also worked at a small startup and saw what it was like to not have a design system. No design system led to copy pasta code, and days of back-and-forth on simple things like “what hex should i be using for the hover state?” Design systems are tricky to get right. Picking an out-of-the-box solution is easy to begin with, but one day you’ll be cursing yourself due to lack of flexibility (we did!). On the other hand, creating a design system from scratch is super time-consuming even for the best frontend engineers. Mirrorful is our way out of this dilemma. Mirrorful is completely open-source and written in Typescript. We’re starting with basic design elements—commonly called “design tokens” — such as colors, typography, and shadows, but have plans to expand our scope into more complex components. As frontend engineers ourselves, we wanted a tool that lives in code but is visual. It had to be super easy to set up, but also prepare you for scale so you and/or your team don’t end up copy-pasting everywhere. We decided to make it an NPM package ( https://ift.tt/nZQMLKl ) that runs a localhost editor and exports out your design tokens into any configuration you want: .js, .ts, .css, .scss, .json. It’s lightweight with no design system lock-in. Our product is completely self-serve: just install our NPM package. If you run Mirrorful locally, a visual dashboard will pop up at localhost:5050 that lets you manage your theme and export various configuration files directly into code. Pricing is similar to other open-source companies—we charge for cloud-hosted features and for premium components. We’ve built open-source/open-core projects before and love interacting with contributors from all over the world. If anyone has any opinions on what we’re building, we’re all ears. Check us out at mirrorful.com and at github.com/Mirrorful/mirrorful and give it a shot! https://ift.tt/0d3wVUW March 29, 2023 at 10:19PM

Equations we are used to think as unplottable (with usable real-time performance), like for example `e ^ (sin(x) * x ^ 2 * cos(y)) = cos(e ^ (x * y))`, will render just as smoothly [0] as something simple, like `y = x ^ 2`. Goals: * Rendering (almost) any equation without performance problems * Enabling acquiring new insights from being able to closely interact with complicated equations * Having an intuitive, easy-to-use and not-buggy interface Non-goals: * Being a general-purpose CAS software KGraph is under active development, and features such as parametric equations are coming in the near future!

Show HN: Datapane – A new way to build reports, dashboards, and apps in Python https://ift.tt/s6xO0tU

Show HN: Datapane – A new way to build reports, dashboards, and apps in Python Hello HN! We’re Leo and Mandeep, founders of Datapane ( https://datapane.com ). We're building a way to create reports, dashboards, and web apps from your existing data using Python. Think of it as a combination of React and htmx, specifically designed for the Python data stack. Our GitHub is https://ift.tt/IatKMZF and you can try building a report or app in ~2 minutes on Codespaces: https://ift.tt/d38mEht We started building Datapane at our previous start-up, where we struggled to deliver ML model results to clients. Much to our surprise, the data science took less time than repeatedly creating reports by copying and pasting plots into PowerPoint decks. It seemed absurd that we had to switch to PowerPoint or legacy BI tools like Tableau to share, and our initial goal was to programmatically generate reports using the datasets and plots we had in Python. To enable this, we started hacking on a Python-based UI framework for constructing HTML views from data-centric blocks – like plots, data tables, and layout components. You can export these to standalone HTML files, or host them as a web app on somewhere like GitHub Pages or Fly.io. We recently also added the ability to connect Python functions to forms and front-end events so you can build web apps which run backend code. We handle the entire network and RPC layer, so you only need to write plain Python functions that take parameters and return other blocks. You can check out an example of the code to create a simple app: https://ift.tt/Yr1OR4d... Datapane’s philosophy is pretty different from other products in the space. We wanted to keep things simple, but avoid the footguns our users faced with frameworks like Streamlit, where the reactive/network-aware model was hard to move beyond an MVP or POC. For backend interactivity, we believe the original web got a lot right, and unlike reactive models which rely on websockets, Datapane is unashamedly request/response. This takes inspiration from HTTP and our own experiences with htmx, which offers an elegant way to add interactivity to HTML. Under the hood, we actually compile down to a (gasp!) XML-based hypermedia format, akin to HTML, but tailored specifically for constructing data UIs. The result is that not every change in your app requires a server round trip, as much of it can be pre rendered and most interactivity happens on the client-side. In addition to improving performance, this also makes running in production become 10x simpler. This separation between the view and backend compute also makes Datapane modular. If our app server isn’t a good fit for your use-case, serve Datapane views from the web-framework of your choice (we’ve been hacking on serving views from Django). Want to compute blocks from inside Airflow or generate them on a schedule or from a webhook? Computation can happen out of band of the UI. You can even build and host apps from inside of Jupyter, where you can preview blocks live and convert notebook cells to blocks in your view. We currently offer a hosting platform on https://datapane.com for sharing reports publicly (free) or with your team (paid), and will be adding serverless app hosting support to it in the next few weeks. Our ultimate goal is to create an open-source toolkit for building data products across the entire stack – from reports, to dashboards, to full-stack apps – all using 100% Python.

Show HN: Zapier universal API (using natural language) Hey HN! We launched Zapier way back in 2012 on HN: https://ift.tt/zGjerDY and thought we'd return home to announce something special and hopefully exciting :) We are trying to finally live up to the "API" in our name with Zapier's first universal API: Natural Language Actions – https://ift.tt/VXk0uqf API docs – https://ift.tt/Dmbph4B (to be fair, we have published APIs before that can access Zapier data, but never before one devs can use to directly call the 5k+ apps / 20k+ actions on our platform) For example, you can use the API to: * Send messages in Slack * Retrieve a row in a Google Sheet * Draft a reply in Gmail * ... and thousands more actions with one universal API We optimized NLA for use cases that receive user input in natural language (think chatbots, assistants, or any product/feature using LLMs) -- but not strictly required! Folks have asked for an API for 10 years and I've always been slightly embarrassed we didn't have one. We hesitated because we did not want to pass along our universe of complexity to end devs. With the help of LLMs we found some cool patterns to deliver the API we always wanted. My co-founder/CTO Bryan did an interview with Garry on YC blog with more details: https://ift.tt/YWgFHwI... We also published a LangChain integration to show off some possibilities: * Demo: https://www.youtube.com/watch?v=EEK_9wLYEHU * Jupyter notebook: https://ift.tt/VovY6sK We know the API is not perfect but we're excited and eager for feedback to help shape it.

A Decade of Rolling out the Red Carpet for Riders

A Decade of Rolling out the Red Carpet for Riders
By Cassie Halls

An animated map showing the expansion of red transit lanes in San Francisco. View as a PDF. Accessible version of the expansion of red transit lanes: 

Red Transit Lanes Over Time in San Francisco from 2013 to 2023 

There is nothing quite like looking out the window at gridlock traffic while your bus coasts down a red transit lane. This may feel like an “only in San Francisco” pleasure – after all, San Francisco was one of the first U.S. cities to “roll out the red carpet” by painting bus lanes red. But red transit lanes have now become a popular way to keep buses out of traffic in more than 25 cities across the country. 

The SFMTA is celebrating a decade since the installation of San Francisco’s first red transit lane on Church Street on March 23, 2013. You can help us celebrate by riding that first red transit lane between Duboce and 16th Streets on Muni’s 22 Fillmore and J Church along with thousands of other weekday riders. As you whiz past traffic, you may feel the estimated 14% time savings afforded by the red color.  

If you drive, help us celebrate by keeping transit lanes clear. Remember, double parking in transit lanes is camera enforced. Transit lanes are an essential tool to keep Muni moving on San Francisco’s busy streets.  

Dedicated transit lanes started popping up in the city as early as the 1970s following the adoption of the city’s Transit-First Policy (which happens to be turning 50 this month). As of 2023, over 20 lane miles of transit lanes now also have the red treatment, in addition to 55 miles of transit and bus/HOV lanes without red paint.  

J Church train using red transit lanes on Church at Market Street. 

Although often the most visible, transit lanes are one of more than 20 tools in our toolbox to improve transit reliability and reduce delays. With Muni Forward, we’ve built more than 80 miles of transit corridor reliability improvements to keep Muni moving — with upgrades like bus bulbs for faster boarding and traffic signals that stay green for transit.  

As an early adopter of red transit lanes, the SFMTA helped lay the groundwork to change federal guidelines to make it easier to paint lanes red. This is because red colorization has led to a 55% improvement in motorist compliance and is a cost-effective way to reduce delays. We have to say they’re looking great for their age! 

We know that despite our best efforts, Muni buses and trains are sometimes stuck in traffic and transit lanes are occasionally blocked. That is why we continue to innovate to bring improvements to our riders. Last year we colorized six miles of transit lanes in the Van Ness Improvement Project, Geary Boulevard Improvement Project, and along Mission Street in SoMa, 4th Street and Stockton Street. We also continue to install Muni Forward transit priority projects across the city and push for further compliance improvements through an education campaign for motorists. The SFMTA was also recently awarded a state grant to deploy new next-generation camera technology as a part of the transit lane enforcement program. 

Stay tuned for more red transit lanes and other reliability improvements in the year ahead.

Show HN: I want to change how people buy health supplements https://ift.tt/xQ4nPcq

Show HN: I want to change how people buy health supplements I made a table where you can find out the source/location of factory for where health supplements are made. Then, I spent a year reading product labels so you can save time and money when buying supplements. This is that update. This is still a work in progress but it functions fine. My previous post was a simple database of company data showing ingredient sourcing/location. That took 10 days, this has taken me close to 9 months. BackOfLabel is an extension of that initial interest with dosage information at the product & ingredient level. This update allows sorting by many more attributes at the product level (for 4000+ products at the moment) of manually scraped data. Now, for instance you can sort by specific types of ingredient - eg. filter by magnesium glycinate , magnesium orotate or any combination. eg. find ubiquinol or ubiquinone, two forms of coenzyme q10. This is useful for consumers but also companies seeking competitor analysis. You are able to filter products by – Ingredient – Filter by liquid, tablet, capsule, powder & more – Browse by UPC Code – Dosage Information – No. Individual Serving – No. Manufacturer Serving – Total Dosage For example You can also search by type of protein powder - eg. search for whey protein powder and find the dosage information for many products instantly. It frustrates me and I think the way that people buy supplements is wrong. And they don't know any better because there are incentive structures that keep them in the dark. This is a small effort to combat the misleading labeling and lack of regulation in the industry. full disclosure - i've provided a generic affiliate link in the table that means i earn a small percentage (5%) of total cart if you purchase through the link note: browse on desktop to filter & sort https://ift.tt/ABXNJLS March 19, 2023 at 07:31AM

100 and Counting – More New Trains Join the SFMTA Fleet

100 and Counting – More New Trains Join the SFMTA Fleet
By Christopher Ward

Muni continues to expand its fleet with its 100th light rail vehicle four-series (LRV4) on San Francisco streets, broadening the reach of transportation in the city! 

The SFMTA received its 100th new LRV4 (light rail vehicle four-series) in December 2022, closing out a year of big accomplishments for the agency. This train represents a milestone in the continued progress of the LRV Fleet Replacement Program.  

The SFMTA is steadily expanding its fleet with about three new LRV4 train cars arriving every month. We expect 219 total cars to be delivered by 2025. This allows us to retire the aging Breda vehicles, which have been in use by the SFMTA since 1955. Compared to the mostly grey Bredas, the new LRV4 trains are easy to spot on the street, with their distinctive “red ribbon” that wraps around the front of the vehicle and down the sides.  

The new LRV4 trains are also far more reliable than the outdated Bredas. With better design and engineering, these trains have fewer breakdowns and require less maintenance. This makes them more reliable and less expensive to operate, which means better service for Muni riders. 

The new LRV4s have improved safety and service features. In response to customer feedback, the seats are color-coded – blue indicates priority seating for seniors and people with disabilities, and red indicates general seating. We also added more visible, yellow grab rails. The LRV4s also have digital displays that show information about upcoming stops and nearby alternate routes at transfer points. These same interior upgrades will be added to earlier LRV4 trains over the next year.  

Learn more about the history of LRVs, look into Muni Light Rail Through the Years and follow us on Instagram (Instagram.com/sfmta_muni).

Tech Talk: Muni Predictions 101

Tech Talk: Muni Predictions 101
By Christopher Ward

New Customer Information Systems are being installed and causing customer curiosity! 

Got a burning question about the SFMTA’s Muni predictions that are made by our Next Generation Customer Information System (CIS)? We’ve got answers! Below are some of the frequently asked questions from Muni customers. Send us yours! 

Where do Muni predictions come from?  

Muni predictions come from data provided by multiple SFMTA systems including equipment on our vehicles. Real-time predictions are based on the real-time locations of Muni vehicles. A computer algorithm compares the real-time data to past travel times based on time of day, day of week, season and other factors that affect travel to predict future arrival times. Travel patterns in this historic data are applied to real-time data to generate accurate Muni predictions. 

When the system has no real-time information, it uses Muni schedules to make predictions. This often occurs at or near terminals and during service changes. However, schedule data isn’t as reliable as real-time data, particularly because the SFMTA has made Muni service more reliable by shifting away from using schedules to headway management, scheduling service at regularly spaced intervals to reduce gaps and bunching, rather than clock times. 

What factors impact predictions? 

The two main problems with predictions are 1) vehicles in service but not showing up in the Customer Information System (we call those “surprise vehicles”) and 2) predictions made from the schedule, but the vehicle doesn't show up (we call those “ghost vehicles”).  

A “surprise vehicle” is when a bus or train is running but it is not picked up by the real-time position data feed. This may be because of damaged equipment, a vehicle not signed into the system when it departs the division, or when changes are not entered into the system. When a vehicle is missing from the system, the wait times at stops appear longer than they actually will be. This happens because the prediction system does not “see” one of the vehicles. 

A “ghost vehicle” usually occurs at stops close to the start of the line. You might see this at the stop when looking at the prediction countdown. When the count gets to zero, no vehicle appears! This happens because the prediction system is not picking up any vehicles while they are at the terminal and before they start the route. This results in the countdown relying on the schedule, even if the vehicle is delayed. If a vehicle is scheduled but not coming, then the countdown will end and there will be no vehicle. The system relies on the vehicle data when it is available, otherwise it will show the schedule information that may not be accurate.  

The same problem occurs with trains as with buses but at an increased rate, because trains cannot pass each other like buses. Because of this, there are often service adjustments made at the control center to manage gaps that result in inaccurate predictions. 

Why do different apps have different predictions sometimes? 

The SFMTA generates vehicle information and shares this data openly for anyone to use cost-free. Third party apps like Transit, Google and Waze, as well as “mom and pop” apps, each have their own way of taking in and making use of the data that we provide. 

These third parties are independent of the SFMTA and we do not keep track of the quality of their predictions. If customers experience problems, we recommend reporting the problem directly to the third-party and checking the predictions at SFMTA.com/Routes. 

What does it mean when a Muni display says, “no predictions available?”  

The “no predictions” message displays when there is no real-time vehicle data to generate predictions, either because the system is down or a vehicle is not logged into the system. This does not mean that isn’t service. Buses and trains are still running. If there is a service issue affecting bus or train operation, the SFMTA will display relevant information, make audio announcements, send out email and SMS alerts and post on Twitter.    

What new features will be added and how can I learn more?  

The Next Generation CIS screens now display real-time vehicle locations on a map and real-time on-board vehicle capacity information, along with arrival prediction times. 

Some of the next features we plan to roll out are real-time alerts such as reroutes and elevator availability. We’re also improving terminal predictions, and we are working on multiple MuniMobile app upgrades.

Show HN: Safe Data Changes in PostgreSQL https://ift.tt/DCNui3R

Show HN: Safe Data Changes in PostgreSQL Hi HN, we're excited to share our open source tool with the community! We previously posted here with the tagline “real-time events for Postgres” [0]. But after feedback from early users and the community, we’ve shifted our focus to working on tooling for manual database changes. We've consistently heard teams describe challenges with the way manual data updates are handled. Seemingly every engineer we spoke with had examples of errant queries that ended up causing significant harm in production environments (data loss/service interruptions). We’ve seen a few different approaches to how changes to production databases occur today: Option 1: all engineers have production write access (highest speed, highest risk) Option 2: one or a few engineers have write access (medium speed, high risk) Option 3: engineers request temporary access to make changes (low speed, medium risk) Option 4: all updates are checked into version control and run manually or through CI/CD (low speed, low risk) Option 5: no manual updates are made - all changes must go through an internal endpoint (lowest speed, lowest risk) Our goal is to enable high speed changes with the lowest risk possible. We’re planning to do this by providing an open-source toolkit for safeguarding databases, including the following features: - Alerts (available now): Receive notifications any time a manual change occurs - Audit History (beta): View all historical manual changes with context - Query Preview (coming soon): Preview affected rows and query plan prior to running changes - Approval Flow (coming soon): Require query review before a change can be run We’re starting with alerts. Teams can receive Slack notifications anytime an INSERT, UPDATE, or DELETE is executed from a non-application database user. While this doesn’t prevent issues from occurring, it does enable an initial level of traceability and understanding who made an update, what data was changed, and when it occurred. We’d love to hear feedback from the HN community on how you’ve seen database changes handled, pain points you’ve experienced with data change processes, or generally any feedback on our thinking and approach.

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT https://ift.tt/vQtiuae

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I asked for a Dewey classification... and it worked. So I replaced a few days of fiddly work with 3 cents per inference and an overnight data run. My takeaway is that I'll be using LLMs as function call way more in the future. This isn't "generative" AI, more "programmatic" AI perhaps? So I'm interested in what temperature=0 LLM usage looks like (you want it to be pretty deterministic), at scale, and what a language that treats that as a first-class concept might look like. https://ift.tt/o6USpnH March 9, 2023 at 02:28AM

Muni Safe Driver Awards 2023

Muni Safe Driver Awards 2023
By Sophia Scherr

Keep an eye out for one of our Safe Driver Award PSA’s on your next Muni ride & don’t forget to thank your operator! 

Driving through San Francisco’s winding and hilly terrain in any vehicle is tricky. Doing so in a 40-foot bus, cable car or streetcar is not as easy as our operators make it seem. Despite these challenges, every day our Muni operators connect San Franciscans to where they need to go safely.  

This Saturday marks the 50th Safe Driver Awards, where we celebrate our transit operators who have put safety first in their efforts to deliver you to your home, work and communities. This year 249 operators earned the distinction of being a Muni Safe Driver. Receiving a Safe Driver award is a hard-earned career milestone — to achieve it, operators must have driven at least 1,952 hours during the past fiscal year (July – June) without a preventable incident or collision. Quite a few operators have maintained their Safe Driver status for several decades. Now that’s a dedication we applaud! 

This Saturday, we’ll recognize the following operators for 35+ years of continued safe driving:  

• Oliverio V. – 48 years (Cable Car) 

• Lonnie M. – 45 years (Green Division) 

• Jason L. – 38 years (Green Division) 

• Eddie C. – 35 years (Cable Car) 

• Andrew M. – 35 years (Cable Car) 

“I can’t thank our operators enough. They show up to work every day with a commitment to keeping our riders safe. Those recognized at the Safe Drivers Awards ceremony display extraordinarily safe driving track records,” said Jeffrey Tumlin, Director of Transportation. “All our operators have worked throughout the pandemic and in very difficult driving conditions or challenging environments with safety as their top priority. They are the heroes that positively represent our agency daily and deserve the utmost praise for their service!”  

The SFMTA and our city rely on our Muni operators to keep the city moving by providing daily service to hundreds of thousands of riders throughout the Muni network. We not only honor these incredible 249 operators, but all the employees who work hard to make safety the standard by which we operate. Next time you ride, don't forget to thank your operator!

Show HN: Plato – Airtable for your SQL database https://ift.tt/UNZ4RvV

Show HN: Plato – Airtable for your SQL database Hi! I've been a member of HN for fifteen years so today I'm very excited to share Plato. Plato is an Airtable-like interface for your Postgres or MySQL database. It's an admin panel for devs and non-devs alike to manage your DB. We see teams use Plato for customer support, customer success, ops, etc.. We built Plato because we think more people should be able to build and extend internal tools. We thought it was strange that even though low-code is supposed to democratize development, all of the low-code internal tool builders are marketed to engineers! Airtable is a familiar UI that fits the relational model well, so we've been inspired by their work. Even the engineers on our team use Plato quite a bit, since it's often easier than spinning up a SQL prompt. Some features: - Postgres and MySQL support - Visual query controls (sorts, filters, hiding columns). No SQL. - Joins by "expanding" foreign keys - Virtual columns for tracking new data - Auto-generated backlinks for one-to-many relationships - Read-only locking for individual tables - Virtual tables for sharing new views with your team Plato today works on databases with a public IP (just whitelist our IP to connect), but we're soon rolling out an on-prem version. We can also set up an SSH tunnel for you if you contact us at team@plato.io. We'd love to hear your feedback! Thanks. - Michael https://ift.tt/ShQgBqO March 8, 2023 at 10:50PM

Show HN: Co-locating Debian Bullseye with an evil maid https://ift.tt/aYpnOK3

Show HN: Co-locating Debian Bullseye with an evil maid In order to facilitate the secure co-location of a server, I looked into protecting a Debian Bullseye system from evil maid attacks. In addition, since I've enjoyed using ZFS for some time, I decided to rely on a natively encrypted ZFS root file system. Basically... I'd like to take a system containing sensitive information, box it up, and drop it in the mail without worrying about losing it or having it wind up in the wrong hands. A couple of things became clear while researching how to do this. First, there should be little chance that a rogue data-center admin can insert malicious software. When the system reaches the data center and gets powered on we should be confident that it's running our software completely unmodified. As I understand things, Secure Boot is designed to help with this and therefore should be enabled. However, by relying on Secure Boot alone, there will be no remote method of knowing that it hasn't been disabled until after the ZFS pass-phrase is provided to the initramfs via dropbear. At that point it's too late. An evil maid could have already subverted dropbear, for example, and just now stolen the pass-phrase. To avoid this I realized that a second requirement of using a TPM device to automatically unlock the ZFS root was in order. TPM devices have the ability of "sealing" data to so-called Platform Configuration Registers (PCR). This feature allows the data to be accessed only if the "measured" system state matches some original expected state. The TPM can fully start the system unattended but, if anything's unexpectedly meddled with, act like a tripwire requiring the pass-phrase to be typed in manually. If we ssh in and reach dropbear requesting the pass-phrase, we'll know that we either need to update our sealed data after a grub/kernel/initramfs update... or someone's been messing with our start up code. This window of opportunity will be too small for an evil maid to take practical advantage of. This sounded like the right track and I set out to try and configure both, Secure Boot and TPM unlocking of an encrypted ZFS root. I thought it'd take a few hours at most but it actually turned out to be a fair challenge. After a few failed attempts I started tenaciously documenting every avenue. Ultimately I developed helper scripts that can reproduce the configuration should the time come to actually ship a machine out the door. I'm reasonably satisfied with the outcome. However, the scripts haven't been reviewed and neither has the overall process itself. There were a lot of guides I followed that contained typos, bugs, dubious information or simply different requirements. I'm not sure everything is exactly "bullet-proof" for this show HN. For example, I'm beginning to wonder if Secure Boot is necessary and if the TPM alone is sufficient. So naturally, comments and criticisms regarding everything are greatly appreciated. The script files can be found here: https://ift.tt/X6y7k5J and here: https://ift.tt/OhsayvK Finally, I hope this effort will be useful to others facing similar needs. March 8, 2023 at 04:19PM

Show HN: Open-Source Alternative to Loom https://ift.tt/j5VQzNi

Show HN: Open-Source Alternative to Loom Hey HN, we're excited to introduce Sorbay - an open source alternative to Loom for creating and sharing screen recordings. With Sorbay, you can easily record your screen, camera, and microphone all at once. It is a complete solution that comes with its own backend service, allowing you to instantly share a link of your recording as soon as it is finished. The video is streamed directly to the backend service as the recording happens to make this possible. With both founders based in different countries, we needed a tool to quickly share screen recordings to keep us up to date or to ask for feedback. Meetings are cool if you need to discuss something deeply, but for almost everything else a quick recording works better. We had to settle for one of the proprietary solutions because none of the open source tools allowed us to quickly share something with each other. Doing the recording is one aspect, but having the ability to instantly share a link was crucial. Waiting on a 400mb video upload to a Dropbox is just too much interruption if you want to quickly share something. The tipping point for us to actually build this open source tool came via an interaction from one of our day jobs. A third party provider sent a screen recording full of confidential information and to make things worse, all of it was uploaded by them to a different third party service. We strongly believe that information like this should stay within a company, ideally on infrastructure that they control themselves. Having a fully integrated open source solution is the best way to go for this. Our goal with this first public release is to gather feedback. The critical code paths are working, but it is still a bit rough to use. We deliberately cut out all non-essential features, but have a clear roadmap on what we want to release this year. There are a couple of known issues like audio glitches, non-working videos in Safari and crashing binaries that we hope to fix in the coming weeks. Later this year, we plan on releasing a cloud hosted version of Sorbay that would let you connect your own S3 storage provider. Additionally, we will be releasing an on-prem option focused on features for enterprises (SSO, RBAC, compliance). Both the Sorbay Client and the backend service are completely open source. For licensing we choose the AGPLv3 throughout the stack. The client is built with Vue.js on top of Electron. The use of Electron might be a bit controversial here on Hackernews but given the resources we currently have that was the only way that allowed us to get a working client out on all major platforms. The backend service is realized with Django. We use Keycloak for authentication and Minio for S3 compatible storage. All of this is run alongside Postgres and Redis, running on Docker containers which are managed by Docker Compose. We invite you to try Sorbay for yourself and join us on our issue tracker[1][2], Slack channel[3] or here on HN. Thanks for checking out Sorbay!

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator https://ift.tt/BytXmnL

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator Hi HN! This is a simple text to entity-relation graph generator, powered by gpt-3 davinci model. The purpose is to feed it actual written data, to obtain a graph representation of entities and relationships mentioned in the text. Also, being able to identify entity attributes like gender, size, age ... My initial goal, was to make it able to process a large amount of text into a big single graph. The problem being the 4000 token limit the model has, I decided to take the approach of feeding the text in batches, and try to merge the incoming graph with the existing information each time. This is done by comparing the incoming node labels with those already in the graph, adding the new information to the existing nodes. This works somewhat, but sometimes entities get duplicated if they are mentioned slightly differently in the text. The comparation method could use some improvement clearly. A nice feature, is that you get to decide what types you want to extract. So if, for example, you are interested only in people, and companies in the text, you can tell the model to stick to that. You can also leave the types to the model discretion. Also, the application allows for saving / loading graphs to json files. These files can be used with Cytoscape Desktop Application, which is a nice side effect of using cytoscape.js. in the UI. I think tools like this can really be of help when going through dense documentation. To have a visual representation of the concepts, entities or whatever, can be really helpful in education, investigation, legal ... Would love to hear your thoughts on how this could be improved. https://ift.tt/FPb6YCE March 5, 2023 at 06:47AM

Show HN: Zipslicer, a library for loading LLM checkpoints on consumer hardware https://ift.tt/F2QslxC

Show HN: Zipslicer, a library for loading LLM checkpoints on consumer hardware This is a low-level opensource library I developed for my own use and decided to share, as it makes it possible to process large checkpoints of neural networks without renting high-RAM instances, on a regular PC. It replaces torch.load() with a custom function that produces a dictionary that materializes tensors on the fly. Compared to other solutions it doesn't require sharding or re-encoding checkpoints and uses them completely as-is. It is a foundation to make it possible to run inference and compress language models and other large models one layer at a time - in principle, even one tensor at a time. I describe the rationale and technical details of the library's design in the blogpost: https://ift.tt/2cIoOUw https://ift.tt/aCMGmrA March 4, 2023 at 02:29AM

Take Muni’s Safety Survey!

Take Muni’s Safety Survey!
By Greer Cowan

Everyone should feel safe on Muni. Help make Muni safer by taking the SFMTA’s survey about personal safety and harassment in the Muni system.  

As part of the MuniSafe Safety Equity Initiative launched in August 2022, the SFMTA has partnered with the UCLA Institute of Transportation Studies to better understand Muni riders’ experiences and develop safety recommendations, tools and policies aimed at preventing harassment and assault on Muni. 

Take the 5-minute survey 

Survey information will also help the SFMTA understand Muni customers’ specific safety needs and challenges, and help us identify valuable trends and patterns so we know where, when and how harassment shows up in the Muni system. 

Incidents often go unreported, but the SFMTA is working to change that with new reporting options. As of October 2022, Muni customers can report incidents of  harassment by calling 311, using the 311 mobile app or using the Muni Feedback form at SFMTA.com/MuniFeedback. Each report is investigated by the SFMTA’s Safety and Security Division, and Muni operators are made aware as necessary. 

The SFMTA is committed to the safety, rights and dignity of all riders and working to combat the disturbing and unacceptable  violence we’ve seen on transit. In recent months, we have seen terrible incidents of anti-Asian verbal and physical violence, derogatory hate speech like racial and homophobic slurs, and increased anti-Semitism. In addition, gender-based harassment is one of the most expansive and persistent forms of violence. It is especially pervasive on transit, most often impacting women, girls and gender-expansive people of all ages, abilities, races and ethnicities, cultural and language groups. Studies show that women often feel unsafe on transit, which impacts how often they ride, when they ride and if they ride at all. This is especially true for women and girls from Black, Asian, Latinx, Indigenous and other communities of color. 

Harassment and safety issues on transit can cause women and gender-expansive people – people who don’t conform to traditional gender roles – to shift their travel behavior by traveling at different times of day, choosing longer routes where they feel safer or using rideshares or private vehicles when they can afford to.

Show HN: Sort Any Awesome List by GitHub Stars https://ift.tt/1SgkVhA

Show HN: Sort Any Awesome List by GitHub Stars As a CS undergrad, I self-taught many topics not covered by the school. Typically awesome list is where I started with. I spent my second half in college researching computer vision and machine learning. CVPR accepts over 2000 papers every year, not to mention arXiv. The awesome lists curated by the community usually serve as checklists when I was doing literature surveys. But since the number of the list items was overwhelming, I had to prioritize which papers to read first. Many of them had been uploaded to arXiv in the last few months, so I had no clue how many citations they would get. When learning web development, I also had difficulty finding the best package for the tasks like data validation and client-side routing. To make a decision, I had to browse through GitHub repositories or read the documentation. I wish I could have my awesome lists sorted, desirably by popularity. This led to the creation of my project: a web app that rearranges any awesome list with hints from GitHub stars. It may not work well when the list items do not contain links to GitHub repositories or pages, but it truly shines when most of them do. I hope this could help anyone else. P.S. I'm aware of a similar project ( https://ift.tt/q5QaP2t ), a CLI application with more features. For example, it checks if any GitHub repository link exists on the linked website. https://ift.tt/WjrG5oI March 3, 2023 at 01:51AM
