Show HN: I was playing with fundamental constants and 13.8 b years popped out https://ift.tt/3nKy2Lk

Show HN: I was playing with fundamental constants and 13.8 b years popped out I was playing around with fundamental constants and out popped 13.8 billion light years. What is going on? the wavelength of an electron mass photon / (2pi) * the charge radius of a proton / the black hole radius of a proton = 13.8 billion light years ((h / (m_e * c * 2pi)) * (h / (m_p * c * pi/2)) / (2G * m_p / c^2)) = 13.8 billion light years https://ift.tt/2Z7G6vk +c+ +2pi%29%29+ +%28h+%2F+%28m_p+ +c+ +pi%2F2%29%29+%2F+%282G+ +m_p+%2F+c%5E2%29+to+light+years&assumption=%22UnitClash%22+-%3E+%7B%22G%22%2C+%7B%22GravitationalConstant%22%7D%7D&assumption=%22UnitClash%22+-%3E+%7B%22m_e%22%2C+%7B%22ElectronMass%22%7D%7D&assumption=%22UnitClash%22+-%3E+%7B%22c%22%2C+%7B%22SpeedOfLight%22%7D%7D&assumption=%22UnitClash%22+-%3E+%7B%22h%22%2C+%7B%22PlanckConstant%22%7D%7D September 18, 2021 at 02:29AM

SFMTA Resumes Peak Hour Tow-Away Zone Enforcement

SFMTA Resumes Peak Hour Tow-Away Zone Enforcement By Jessie Liang The SFMTA’s towing programs were temporarily suspended in March 2020 in response to the COVID-19 pandemic. As the city has reopened and traffic has returned, the SFMTA will resume enforcement of peak hour commuter tow-away zones starting September 20 . Vehicles parked at tow-away zones during restricted peak hours will be subject to citation and towing.  We’re bringing back the enforcement of peak hour tow-away zones under the SFMTA Transportation Recovery Plan (TRP) as the economy reopens. Tows help the SFMTA facilitate the flow and safety of transit and traffic, support economic activity and maintain safe streets. The reinstated tow-away enforcement will accommodate changing conditions on city streets. For example, enforcement will not apply to Shared Spaces that allow merchants to use sidewalks, full or partial streets and other nearby outdoor spaces under San Francisco’s Public Health Orders. In addition to

Long-awaited crosswalk on Geary helps rebuild community connections

Long-awaited crosswalk on Geary helps rebuild community connections By Amy Fowler The Geary Rapid Project just met another major milestone with the completion of a long-awaited crosswalk connecting the Japantown Peace Plaza to the southside of Geary Boulevard. The new crossing at Geary and Buchanan Street serves as a physical reconnection to help bridge the gap between divided communities. But it’s also a symbolic one , exemplified by the decorative panels installed in the center median that were inspired and designed by the communities it now serves—the Fillmore, Japantown and St. Francis Square Cooperative. A new crosswalk was installed at Geary and Buchanan, with decorative panels representing the surrounding communities. The significance of the crosswalk is tied to the history of the neighborhood. In the 1960s, the two neighborhoods were specifically targeted by urban planners, the vibrant Fillmore neighborhood --known as “the Harlem of the West” for its phenomenal jazz sce

Bikeshare Station Expansion and e-Bike Price Changes

Bikeshare Station Expansion and e-Bike Price Changes By Adrian Leung As San Francisco's Bikeshare program administrator , the SFMTA recently approved a price increase for Bay Wheels stationless e-bike trips that will take effect September 22, 2021. Bikesharing systems have been an important contribution to the rise in popularity of bicycling in San Francisco over the past decade. Bikeshare programs lower barriers to bicycling by overcoming the challenges of owning, storing and securing one’s own vehicle. Shared bicycles also offer a solution for the "last mile" connections that allow for more effective travel by transit so that one can complete their so-called “last mile” to their destination by bicycle. The SFMTA regulates bikeshare service in order to provide equit able access to shared bicycles for all San Franciscans, as well as ensuring proper placement of stations or unstationed vehicles.  Before and throughout the pandemic, bicycling has increased, and our bik

Show HN: Fusion – Open-source user analytics and engagement suite https://ift.tt/3zcPUjZ

Show HN: Fusion – Open-source user analytics and engagement suite Hello everyone, Vikas & Magus here. We are building Fusion (https://www.fusionhq.co), an open-source all-in-one user analytics and engagement platform somewhat similar to CleverTap & Sprig (UserLeap). It is built upon a simplified low-code mixpanel-like analytics engine with built-in live-chat, push-notification and email/micro-surveys. Fusion shows how your users interact with your web based products eg: page-views, button clicks, form submissions etc. But apart from this, Fusion lets you engage with a specific user or group of users who have something in common or perform a particular action, in real-time with live-chat, in-app push notification, email/micro-surveys or set it up to trigger automatically. Story : After getting rejected in Y Combinator-W21 interview and listening to the feedback we scrapped our previous project and started to work on a simplified open-source alternative to mixpanel/amplitude for

Cable Car Shutdown Update

Cable Car Shutdown Update By Last Thursday at approximately 1:30 p.m., the fire suppression system in the electrical room at the Cable Car Barn at Mason and Washington streets discharged. This caused the electrical room to fill with fire retardant material resembling smoke, which prompted a response from SFFD as a safety precaution. Upon the discharge of the fire suppression system, other automated safety systems were activated resulting in a loss of electrical power to the entire facility, including the propulsion system for the cable cars. As the cable cars only recently came back to full service on Sept. 4, we share the public’s disappointment to now be without these essentially San Francisco features on our streets. Our electrical, operations, safety and facilities teams are working hard to ensure that we do thorough inspections across related systems, rigorous testing and careful resumption of service to avoid further disruption. We are grateful for the quick response and suppo

How Youth Can Shape Muni Moving Forward

How Youth Can Shape Muni Moving Forward By Kharima Mohamed MTA’s 2022 Muni Service Network survey is currently underway and we want to be sure that young people’s voices are heard. Youth now have an opportunity to vote on what type of Muni service they want to see in 2022.  As part of our 2022 Muni Service Network virtual open house and office hours series , we will be holding youth-centered virtual office hours on Thursday, September 23 at 6 p.m. Youth are encouraged to join to find out how the three proposed scenarios for winter 2022 Muni service would change how they get to school and to activities around San Francisco. Youth will be able to ask questions and get answers from SFMTA staff about what matters to them most about Muni service in 2022. Three alternatives have been developed to help us determine what Muni service should look like in 2022: the Familiar alternative, the Frequent alternative and the Hybrid alternative. The Familiar alternative  brings back the all-da

Show HN: Bubbles – JavaScript Library for cross connected charts and dashboards https://ift.tt/3z9o5sK

Show HN: Bubbles – JavaScript Library for cross connected charts and dashboards Hey, I'm the creator of BubblesJS. URL: https://bubblesjs.com/ BubblesJS is a javascript library for creating cross connected charts and dashboards. Key features - Supports chart types like line charts and bar charts. - Support common UI widgets like interactive Tables, Filter Bars and KPIs - charts and widgets can be composed together to create a dashboard of cross connected charts - tiny library < 15KB gzipped This library is motivated by my experience building charts and dashboards for my employers. Using traditional charting libraries gives basic chart types, but applications usually require other UI widgets like tables, applying filters etc which need to be built. Connecting these components requires lot of glue code to pipeline data, transform and filter it and connect these widgets. BubblesJS provides an intuitive API to allow connecting charts and transforming data while also providing cross
