Show HN: Smartphone haptics for inducing calm, an alternative to meditation https://ift.tt/KzRPcZC

Show HN: Smartphone haptics for inducing calm, an alternative to meditation Hey HN, We've been working in neurotech over the past few years, primarily focusing on improving sleep. A friend asked if I would build her a vagal nerve stimulation device. These are devices used to improve relaxation, and “vagal tone”. She didn't want to shell out hundreds for the existing solutions. I originally said no, but then I thought, what if we leveraged smartphone haptics to achieve the same effect as these expensive devices? After some tinkering, Harbor: Immersive Calm was published to the app store last week. https://getharbor.app It’s pretty basic and very MVP, no logins, just: 1)open the app 2) select an immersion (mix of sound and haptics) 3) select how long you want to be immersed (?) 4) lay back, put your phone on your chest, and feel the sensations. In comparison to meditation, with Harbor, there is no “doing it right”, : Lay back, Tune In & Chill Out. I initially built for Android, but the fine-grained control and consistency of haptic motors in iOS device is a better experience. Though, I’m not ruling out a future dive into Android. Here’s a video demo( https://youtu.be/gr70kY9_Abk ) for a sneak peek. Though, without the haptic feedback, you can’t really get a feeling for the experience. Compared to devices the cost hundreds of dollars plus subscriptions, we’re thinking of a subscription model of $5/month. A friend who is a trauma therapist said she’d recommend it to some of her clients, and of course, there is the market of people who are looking to buy vagal nerve devices, and we can offer a lower cost alternative - and you don’t have to wait for shipping :) https://ift.tt/zOVHAe7 October 6, 2023 at 12:58AM

SFMTA Projects Honored as Exemplars of Community Engagement

SFMTA Projects Honored as Exemplars of Community Engagement

The Central Subway and the Potrero Yard Modernization Project were both nationally recognized by the International Association for Public Participation at the IAP2 USA Core Values Awards in Seattle, Washington this September. Each year, the awards go to projects that demonstrate public engagement best practices and advance the field of public engagement.  

Both the Central Subway Project and Potrero Yard Modernization Project are prime examples of the positive effects that community engagement and effective public participation can have on public projects and programs. Both projects embody IAP2’s core values centered on the belief that the people affected by a decision have a right to be involved in decision-making and participate in shaping outcomes.  

Central Subway 

The Central Subway was awarded the Diversity, Inclusion and Culture Core Values Award and the Project of the Year Award for engaging with the diverse communities and neighborhoods impacted by the project. Our team focused on ensuring community voices were heard from day one of project planning up until the opening day of service for San Francisco’s first new subway in 50 years.  

Public input was critical in determining the locations of four new Central Subway stations, station design and station elements such as gathering spaces, retail spaces and a police sub-station. Diverse communities across San Francisco helped to shape the future of the subway thanks to a culturally appropriate outreach approach that ensured the community was heard and respected over the two decades of planning and construction.  

“The consistent commitment to outreach and involvement over a 20-year period is remarkable, through all the demographic changes, neighborhood transitions, changes in city administration and more recently the COVID pandemic. Most often, public participation occurs during the planning stage with only infrequent updates during construction,” said IAP2 USA President Heather Imboden. “[The] SFMTA provided a very good explanation of the initial problem and how additional problems that came up over time were addressed. They made strong use of multilingual ambassadors from the community while providing funding for initiatives to help the community.”  

The agency worked closely with valued community partners, including the Chinatown Community Development Center (CCDC), Community Youth Center (CYC), Chinatown merchant groups, Union Square Alliance, Yerba Buena Alliance, the Bayview community and many others. 

Potrero Yard

Members of the public take a tour of the Potrero Yard in 2019 as part of the award-winning outreach program recognized in September by the International Association for Public Participation (IAP2). 

The Potrero Yard Modernization Project was awarded the General Project Award with its work to build a new state-of-the-art bus maintenance and storage facility that integrates affordable housing. It is the first joint development project of its kind in the United States.  

The project not only expands and modernizes a 100-year-old bus yard but also provides much-needed housing, community spaces and services that have been co-designed with the community. Community input continues to shape the project through initial planning, a sensitive procurement process and the launch of the City’s first public-private partnership to the 100% schematic designs we have today.  

IAP2 President Imboden commented, “It was remarkable that what could have been approached by [the] SFMTA as a simple modernization of a bus yard project instead acknowledged the community’s gentrification issues and created a multiple benefit project that addressed the community’s affordable housing challenges in a meaningful way.”  

A key part of the project’s engagement has been the Potrero Yard Neighborhood Working Group that was created in 2018. This group serves as a conduit to the greater community. Bilingual English-Spanish communications have also been part of public engagement from the start. 

For more information about the Potrero Yard Modernization Project, visit the project page (SFMTA.com/PotreroYard). 

The International Association for Public Participation’s guiding principles have been the foundation for the SFMTA’s Public Outreach and Engagement (POETs) program since its inception. To view the awards submissions and videos, visit the IAP2 2023 USA Core Values Awards website.

Show HN: Dittofeed v0.5.0 – Self-host SMS and email customer messaging Hey HN, we’ve just released Dittofeed v0.5.0, with the primary change being the addition of SMS as a messaging channel. Dittofeed is an open source (MIT licensed) omnichannel customer engagement platform, similar to Customer.io and Iterable. We added: - Twilio-based SMS messaging. You can create SMS templates and customer journeys within Dittofeed. SMS is a great channel for B2C software companies, looking to engage with their users. For example, e-commerce businesses commonly use SMS to support checkout flows. We'll be making further enhancements to Dittofeed's SMS support in the coming weeks! - We added a new "Trait Exists" segmentation option, which can be used to create a segment of all users with phone numbers, for example. - We made some fairly large improvements to our settings UI. Big shout out to our contributor! https://ift.tt/E91jIsC The full feature release blog post can be found here: https://ift.tt/4iwGEtM . Looking forward to your thoughts and feedback!

New Rebate Programs Will Help Taxis Go Electric

New Rebate Programs Will Help Taxis Go Electric
By Asher Eskind

We are proud to announce the launch of two groundbreaking rebate programs to spearhead efforts to reduce vehicle emissions in the city's taxi industry. Supported by a generous grant of nearly $350,000 from the Bay Area Air Quality Management District (BAAQMD) and the San Francisco County Transportation Authority (TA), these initiatives represent a significant step towards a more environmentally friendly transportation landscape.

Clean Air Taxi Rebate: Accelerating the Shift to Electric Taxis

Building on its success since the program’s inception in 2012, the Clean Air Taxi Rebate program has been instrumental in reducing emissions from San Francisco's taxi industry. Low-emission vehicles comprise over 90% of the city's taxi fleet, making it one of the cleanest in the nation. 

Now, the SFMTA is taking a bold step forward to transition to a completely zero-emission taxi fleet. Under the Clean Air Taxi Rebate program, we will provide rebates ranging from $3,750 to $30,000 to qualifying taxi companies and operators who upgrade their previous gas-powered or hybrid taxis to electric vehicles (EVs). 

To participate in this program, taxi companies and operators must purchase an EV, and both new and used EVs are eligible for rebates. Participants also have the flexibility to lease EVs if they prefer.

EV Charging Infrastructure Rebate: Fueling the Future with Charging Stations  

In conjunction with the Clean Air Taxi Rebate, the SFMTA is introducing an EV Charging Infrastructure Voucher Rebate program to bolster the city's EV charging infrastructure, specifically for electric taxis. The SFMTA will provide a rebate of 90% of the total cost for the construction of EV charging stations. The estimated cost is $90,000 per charger for DC fast chargers with a six-vehicle-per-day capacity, which would yield a rebate of $81,000. To ensure efficient use of these charging stations, this rebate is exclusively available for permitted taxi companies.  

Both Programs: Transforming Transportation Together

Both the Clean Air Taxi Rebate and the EV Charging Infrastructure Rebate programs operate on a first-come, first-served basis and are expected to run for two years or until funding runs out. Should participation levels exceed expectations, the SFMTA will consider requesting additional funding from the BAAQMD and the TA on an annual basis to sustain these programs beyond 2025.  

If you have questions about these innovative rebate programs, please send an email to sftaxi@sfmta.com.  

For more detailed information regarding the EV taxi rebate please visit the Clean Air Taxi Rebate page (sfmta.com/clean-air-taxi-rebate) and for more information about the EV charging infrastructure visit the EV Charging Installation Rebate Page (sfmta.com/ev-charging-infrastructure-rebate).

Show HN: Running LLMs in one line of Python without Docker https://ift.tt/0lrazYD

Show HN: Running LLMs in one line of Python without Docker Hello Hacker News! We're Yangqing, Xiang and JJ from lepton.ai. We are building a platform to run any AI models as easy as writing local code, and to get your favorite models in minutes. It's like container for AI, but without the hassle of actually building a docker image. We built and contributed to some of the world's most popular AI software - PyTorch 1.0, ONNX, Caffe, etcd, Kubernetes, etc. We also managed hundreds of thousands of computers in our previous jobs. And we found that the AI software stack is usually unnecessarily complex - and we want to change that. Imagine if you are a developer who sees a good model on github, or HuggingFace. To make it a production ready service, the current solution usually requires you to build a docker image. But think about it - I have a few python code and a few python dependencies. That sounds like a huge overhead, right? lepton.ai is really a pythonic way to free you from such difficulties. You write a simple python scaffold around your PyTorch / TensorFlow code, and lepton launches it as a full-fledged service callable via python, javascript, or any language that understands OpenAPI. We use containers under the hood, but you don't need to worry about all the infrastructure nuts and bolts. One of the biggest challenge in AI is that it's really "all-stack": in addition to a plethora of models, AI applications usually involves GPUs, cloud infra, web services, DevOps, and SysOps. But we want you to focus on your job - and we take care of the rest "boring but essential" work. We're really excited we get to show this to you all! Please let us know your thoughts and questions in the comments. https://www.lepton.ai/ October 4, 2023 at 10:07PM
