Show HN: GJP-4-GPT, a Gradual JSON Parser for GPT's Often it's easiest to have an LLM output the results you need in JSON form, but streaming those outputs into an actual viewport is nontrivial. Thus I made this package, a streaming JSON parser that handles all the work of decoding your JSON so you can focus on displaying your UIs. https://ift.tt/0sPGhCz November 23, 2023 at 02:23AM

Show HN: Gaming Gaiden: A lightweight gaming time tracker in PowerShell https://ift.tt/xmhyYTu

Show HN: Gaming Gaiden: A lightweight gaming time tracker in PowerShell Hi Everyone, I made a Powershell application to track time spent playing pc / emulated games. It provides many other interesting statistics as well over long term that can add value to someone's gaming hobby imo. I used to use a closed source program called Gameplay Time Tracker for time tracking focused on gaming, but overtime it started failing and throwing exceptions everywhere. I tried reaching to its Developer to ask if they can open source it and i can fix the problems. I couldn't raise them. It had been truly abandoned. After a while i just decided to build a replacement. Few choices that may seem strange, using Powershell for a GUI application, building the GUI with HTML, CSS and JS instead of native windows forms. All of these were made because i am not a windows app dev / GUI dev. I am infra engineer and have strong scripting skills. Instead of getting bogged down in learning a whole programming language like C# and .Net., decided to go with Powershell. DataTables and ChartJs made it trivial to create the UI. Pragmatic choices over conventional wisdom basically. It turned out well in my opinion. Got some attention on reddit and in a youtube channel. Thought it would be good to share here as well. https://ift.tt/c5IFdMW November 21, 2023 at 11:10PM

Temporary Parking Changes Will Support Valencia Street Businesses

Temporary Parking Changes Will Support Valencia Street Businesses

Valencia Street is home to one of the city's most eclectic and culturally diverse sets of restaurants, shops, nightlife and essential services. The heavily traveled corridor attracts residents and visitors of all ages and interests who get there by walking, biking, rolling and driving.  

As part of our work to make Valencia Street safe and inviting for everyone, we’re making some temporary changes to our loading zones beginning this week to create more general parking on the corridor during the holiday season. These changes will help customers who drive patronize Valencia businesses while keeping the street safe for people on foot, bicycles and scooters. Small businesses are an important part of all that makes San Francisco the incredibly special city that it is, and we all benefit when they succeed. 

In the years since the COVID-19 pandemic hit, the Shared Spaces Program’s parklets and weekend block closures along Valencia have offered a lifeline for businesses and created space for neighbors to come together in joy and community. At the same time, the parklets removed commercial and passenger loading space and parking spaces, and there has been an increase in pick-up and delivery business. The result has been increased competition for limited curb space.  

In response to the concerns of struggling local businesses, we are temporarily adjusting the type and duration of many of the loading zones on Valencia Street between 15th and 23rd streets and on several side streets (18th, 19th, 20th, 22nd) to create more general parking availability in the neighborhood. These temporary changes will be in effect while the project team evaluates permanent curb changes that would be made in early 2024. 

Short-Term Adjustments to Support Small Businesses 

  • We are temporarily turning just over a third (34%) of the loading zones that we recently installed into general parking after 12 noon. 

  • We are also temporarily turning the vast majority (82%) of the new loading zones into general parking after 6 p.m. Previously they ended at 10 p.m. 

  • We are temporarily converting about a third (34%) of the 6-wheel loading spaces into regular commercial loading spaces.  

In addition to on-street parking, the SFMTA operates two garages in the neighborhood: the Mission-Bartlet garage at 3255 21st Street and 16th and Hoff garage at 42 Hoff Street. Parking rates at the Mission Bartlett garage range from $2.00 an hour to $5.00 an hour, depending on the time of day, and the rate at the 16th and Hoff garage is $4.00 an hour (see lists below). Drivers who park in either garage are likely to spend less time looking for a space than those who choose to park on the street, and up-to-date space availability information for the Mission Bartlett garage can be found at our Demand-Responsive Parking Pricing page (SFMTA.com/ParkingRates).  

Mission Bartlett Garage: Open Sunday to Thursday from 7 a.m. to 10 p.m., and Friday to Saturday from 7 a.m. to 12 a.m. Parking rates by time are in the list below: 

  • 12 a.m. to 9 a.m.: $2 per hour. 

  • 9 a.m. to 12 p.m.: $3 per hour. 

  • 12 p.m. to 3 p.m.: $5 per hour. 

  • 3 p.m. to 6 p.m.: $3 per hour. 

  • 6 p.m. to 12 a.m.: $5 per hour. 

16th & Hoff Garage: Open daily from 8 a.m. to 9:30 p.m. Parking is $4 per hour all day. 

Meanwhile, we offer neighborhood businesses the opportunity to purchase parking validation stickers at half price. This allows businesses to offer their customers and employees discounted parking at Mission-Bartlet and Hoff Street garages at a very low cost. Interested merchants can reach out to David Dunham at David.Dunham@sfmta.com or 415.701.4604. 

The Mid-Valencia Bikeway Pilot Project 

We began efforts to improve bikeways along Valencia in 2018 to make the street work better for everyone, and the Mid-Valencia Bikeway pilot project began on August 1, 2023. The pilot includes the following changes: 

  • Center-running bikeway to provide a dedicated and clear path for people on bikes. 

  • Turning restrictions to eliminate or reduce the likelihood of collisions involving turning vehicles. 

  • The restriction of parking near intersections, known as “daylighting,” to help drivers to see people about to cross the street. 

  • Curb management changes to provide more space for loading vehicles and prevent drivers from double parking. 

We are closely evaluating the pilot’s design and will consider adjustments to improve safety and effectiveness. Public input and experiences are instrumental in this process.  

Valencia serves as a major bike route, but most of the corridor is on the city's Vision Zero High Injury Network, the 12% of streets that account for 68% of the city's fatal and severe traffic collisions. While there is no perfect solution, we are committed to improving safety for bicyclists and pedestrians while preserving the economic vitality of Valencia Street.  

As we move forward, SFMTA staff plan to return to the agency’s Board of Directors in early 2024 with an update on how the pilot project is performing. Safety remains our top priority, and our evaluation will encompass a comprehensive range of factors. These include measuring bikeway blockages, vehicle turn restriction compliance, close calls, vehicle speeds and bicycle and vehicle behavior at new intersections with bike signals. Beyond these metrics, we will assess the effectiveness of the new curb management plan, traffic and user volumes, emergency vehicle access, and the interaction of cyclists with the center-running protected bikeway. This evaluation will help us understand how the pilot design is working and whether we need to revise it for enhanced safety and efficiency. 

Two studies are also underway to help inform a future design for Valencia. The first is focused on traffic and circulation to assess the impacts of various design concepts. The second is a public realm/public space study to consider how we can ensure that the corridor is a great place to visit and spend time outside.  

Questions or comments? You can send feedback about the Mid-Valencia Bikeway pilot and the corridor, in general, to Valencia@SFMTA.com, and updates are available at our Valencia Bikeway Improvements project page (SFMTA.com/Valencia).

Show HN: I made a conversational language learning chat UI with gpt4-1106 https://ift.tt/MuYJAmC

Show HN: I made a conversational language learning chat UI with gpt4-1106 Hi, I built JoJo, a personal conversational language learning chat interface. video demo here: https://ift.tt/LtB426e You can chat casually in both your native and foreign language, translate from your native to foreign language, and get grammar explanations. There is explanation mode when having a conversation which corrects and explains what you type. This can be turned off so you can just chat back and forth in your foreign language. I have a 1395 day streak with duolingo Italian so I wanted to build something to help with conversational practice. There are 15 languages supported to choose from. Any feedback or suggestions is greatly appreciated. Thank you - Kyle https://www.jojo.so/ November 20, 2023 at 08:27PM
