Show HN: Track your bone health, help create better bone health treatments https://ift.tt/AYU7qbZ

Show HN: Track your bone health, help create better bone health treatments When I was 32 years of age I was told that my bones were like that of an 80 year old due to a health disorder called Osteoporosis. Osteoporosis can make our bones fragile and likely to break. 1 in 3 women over the age of 50 years and 1 in 5 men will experience osteoporotic fractures in their lifetime. It is likely that your parents and grand parents are already suffering from Osteoporosis. Osteoporosis is identified using a Bone Mineral Density(BMD) scan test which gives scores for our bone density and is compared with the known scores from the healthy individuals of same age. I was told that these known scores does not include all races, ethinicities and are generally unreliable for those with pre-existing diseases. This makes it difficult for providing proper healthcare, Even more so for outliers like me. I'm attempting to change that with Bone Health Tracker. Bone Health Tracker classifies the Bone Mineral Density(BMD) scan test report to display the reports with visualizations to better understand the bone health and to monitor the progress of bone health treatments . 1. Healthcare providers currently have to manually compare the BMD reports of their patients every year to analyze the treatments, With Bone Health Tracker's dynamic chart feature they can now do it automatically and even patients can track the progress of their treatments. 2. Skeleton visualization helps to easily understand which bones are affected by Osteoporosis, Osteopenia even by those without prior medical training. 3. BMD scan test reports without any personal information can be submitted for the research of bone health and treatments for bone health diseases. No Protected Health Information (“PHI”) is collected during the entire function of Bone Health Tracker as only assessment section of the BMD scan test report is needed. If you (or) a family member has taken a BMD test, Consider using Bone Health Tracker to monitor the progress of your treatment and submitting the non-personal data for research. If you are researcher dealing with bone health, or know anyone who would be interested in the data gathered by the Bone Health Tracker and help improve it; Please get in touch. Thank you for reading. https://ift.tt/vs6VHmd November 2, 2022 at 09:30PM

Potrero Yard Modernization Project Reaches Milestone

Potrero Yard Modernization Project Reaches Milestone
By John Angelico

The Potrero Yard Modernization Project has reached a key milestone to replace the obsolete, 107-year-old Potrero Bus Yard with the nation’s first joint development of a bus facility with housing constructed on top. Today, the SFMTA Board of Directors approved awarding the project’s predevelopment agreement (PDA) to Potrero Neighborhood Collective, LLC (PNC) as lead developer (LD). This milestone serves as a starting point for Potrero Neighborhood Collective to work together with the City and project stakeholders to further develop the current concept design and start the process that will produce the final project and housing agreements. 

The successful proposal’s conceptual design is for a modern, three-story bus storage and maintenance transit facility and approximately 575 affordable rental units for those with low or moderate incomes. This unique use of a public resource to advance the City’s housing goals while improving desperately needed transit infrastructure would make the facility the first of its kind in the nation.  

Approximately half of the units are planned for low-income seniors, families and single-occupant households. The “low-income” designation is based on earning levels of 80% or below of the Area Media Income (AMI). The remaining units will be available to “moderate income” households earning between 80% and 120% of the AMI. Many SFMTA staff, including bus operators and maintenance staff, fall within this income bracket. 

The ambitious affordability goals for the housing component are reliant on competitive non-City sources, and should the project not secure these sources on a schedule that can accommodate the construction of the bus yard facility, the housing program may need to be amended  

Planning for the project included multiple outreach events with community members and organizations, as well as the formulation of the Potrero Yard Neighborhood Working Group, an advisory panel made of community stakeholders, housing advocates, nearby neighbors and transit operators. The successful proposal includes input received from the community and is consistent with City policies on anti-displacement, inclusive communities and creating stable housing for vulnerable populations.

This view looks at the SW corner of Bryant and Mariposa streets, and shows how housing elements might be situated atop a three-story, all-electric bus facility. The concept design includes commercial space fronting Bryant Street with ground floor spaces that anticipate uses by community-based organizations and small businesses, that would complement the existing neighborhood-serving commercial presence there. The concept design showcases a commitment to being a good neighbor to the community. For example, the building massing is oriented to minimize shadowing on Franklin Square Park with a design strategy that steps down the building height as it ranges from the highest point at Mariposa Street towards lower heights at 17th Street adjacent to the park.  

The Potrero Neighborhood Collective (PNC) team is led by its sole equity member, Plenary Americas US Holdings Inc. (Plenary). An investor and developer of public infrastructure, Plenary has a long track record of delivering complex infrastructure, project finance and public private partnership (P3) projects. PNC also includes veteran San Francisco affordable housing and housing developers Mission Economic Development Agency (MEDA), Young Community Developers (YCD), Tabernacle Community Development Corporation (TCDC), and Presidio Development Partners. Rounding out the team are design consultants IBI Group and Y.A. studio; providing preconstruction services from the general contracting and construction management perspective are Plant Construction Company and The Allen Group; and infrastructure facility management consultant WT Partnership.  

When the SFMTA launched the Building Progress Program in 2017 — a $2.3 billion multi-year effort to repair, renovate, and modernize the Agency's aging facilities —the first facility to be prioritized for an overhaul was Potrero Yard. Potrero Yard houses bus routes that service neighborhoods across the city, including many communities that are heavily reliant on transit. Routes include the 5 Fulton, 5R Fulton Rapid, 6 Haight/Parnassus, 14 Mission, 22 Fillmore and 30 Stockton.  

The current yard does not meet up-to-date seismic safety standards and is unable to adequately support modern maintenance and cleaning. The design of the new bus facility would provide adequate space and operational flow for bus maintenance, parking and circulation of the bus fleet. A modernized facility will create better working conditions for the frontline workforce entrusted with keeping the buses in safe operation and reduce downtime for buses for both scheduled and ad-hoc repairs. A new facility would make possible Muni’s transition to an all-electric fleet that uses trolley and battery electric buses (BEBs), a critical component in the City’s efforts to address climate change. The new facility is planned to have a fleet capacity of 213 buses, an increase of over 50% from current levels.

Addressing the City’s affordable housing goal while creating a transit facility – one that will prepare the Agency for another century – demonstrates SFMTA’s continued national leadership in delivering sustainable transit and shows a capacity for creative thinking to address San Francisco’s housing goals.

Show HN: Minimax – A Compressed-First, Microcoded RISC-V CPU https://ift.tt/bSvoyir

Show HN: Minimax – A Compressed-First, Microcoded RISC-V CPU RISC-V's compressed instruction (RVC) extension is intended as an add-on to the regular, 32-bit instruction set, not a replacement or competitor. Its designers intended RVC instructions to be expanded into regular 32-bit RV32I equivalents via a pre-decoder. What happens if we explicitly architect a RISC-V CPU to execute RVC instructions, and "mop up" any RV32I instructions that aren't convenient via a microcode layer? What architectural optimizations are unlocked as a result? "Minimax" is an experimental RISC-V implementation intended to establish if an RVC-optimized CPU is, in practice, any simpler than an ordinary RV32I core with pre-decoder. While it passes a modest test suite, you should not use it without caution. (There are a large number of excellent, open source, "little" RISC-V implementations you should probably use reach for first.) https://ift.tt/D3UIKk7 November 1, 2022 at 10:41PM

Showdown at the Cow Palace

Showdown at the Cow Palace
By Lori Phelan

Some of the agency’s most skilled transit operators, mechanics and parking control officers recently polished up their silver stars and rode into Daly City for an epic showdown at the Cow Palace. It was a chance to show they were the best of the best. And boy did they deliver!

....

The SFMTA Roadeo had dozens of transit operators navigate through a course containing various obstacle while under a strict time limit. 

The event was the 32nd Annual Bus Roadeo (and yes, you read that correctly). The name "roadeo" is derived from the better-known horse rodeo competition. The original roadeos, which began in 1937, featured trucks in various categories going through the same obstacles that drivers go through today. The agency took on the moniker in 1974 and held the inaugural event in the parking lot at the former Candlestick Park. It was there a dozen transit operators competed to determine who would lasso the award as best driver. There have been numerous Roadeos over time – 31 to be exact – but the event has been dormant since 2016. Bringing it back now is about so much more than bragging rights. “The Roadeo is about celebrating safety and customer excellence,” said Transit Director Julie Kirschbaum. "And that’s something we can all strive for at any time."

As part of the contest, dozens of transit operators had to navigate 40’ buses through a course containing various obstacles while under a strict time limit. A few of the boxes they needed to check included driving through a narrowing lane that is only 3-inches wider than the bus and stopping within inches of a simulated curb. As drivers negotiated the obstacle course, the buses were also equipped with a device that generated a smoothness of operation score.

Muni mechanics also competed in their own competition. Teams faced off in multi-test challenges that featured simulated vehicle problems and breakdowns. Participants were tasked with diagnosing and repairing issues in a timed contest. They were joined by many of the agency’s parking control officers who competed in their own three-wheeled interceptors, navigating a very tight, timed course.

Parking Control Officers competed against each other navigating a maze that had them perform complex maneuvers at various points. 

According to event frontrunner and Transit Senior Operations Manager Leda Rozier, "This event is about so much more than a skills contest (although that’s important), it’s about building on teamwork, morale and communication. The rest of us at the agency have certainly been impressed and consider ourselves lucky to call all the competitors our colleagues."

Several vintage buses (No. 42 the 1938 White; No. 2230 the 1956 Mack; and No. 3287 the 1969 GMC) along three of our newest battery electric buses from each manufacturer from the pilot fleet were on display, as well as a private car collection. Shown with transit operator competitors.

Winners and organizers will be honored at the SFMTA Board of Directors meeting at 1 p.m., Nov. 1 at City Hall, Room 400. Meetings are open to the public and are streamed live through SFGovTV.
