Safe and Secure Restroom Access Helps Muni Run On Time

Safe and Secure Restroom Access Helps Muni Run On Time
By Adrienne Heim

For those working in the field and delivering transit service, restroom access is not as easy as you may think. Bathroom breaks are a human necessity and require advanced planning for our thousands of transit operators. This is particularly true during the pandemic, as the shelter in place guidelines closed many restaurants and offices that were previously available to our transit staff.

Muni operators provide essential transit service in San Francisco

As the city looks forward to reopening, the SFMTA wants to ensure that all San Franciscans will be able get around the city safely and quickly. This means continuing to invest in maintaining the infrastructure that makes it possible for transit operations to be carried out. And that includes ensuring our Muni bus operators have safe and secure restroom access at the beginning and end of their routes.

Seven years ago, SFMTA’s Operator Restroom Taskforce was formed with a single mission – to overcome obstacles and provide safe, clean and reliable restroom access for staff working in the field throughout the city. And that is exactly what the team members represented by nearly every agency division, including members of Transport Workers Union Local 250A have been doing.

Since 2012, the group has been successful in delivering additional access at key locations, bringing the total number of available restrooms location to 151. This includes securing licenses and free restroom agreements with businesses, buildings, and organizations, portable units and permanent SFMTA dedicated operator restroom facilities.

Completing A Refresh of Older Operator Restrooms 

Between 1990 and 2005, 17 standalone restrooms were constructed to kickstart supporting operators out in the field. 

Geneva Avenue and Munich Street Operator Restroom built in 1990

Throughout 2020, the Operator Restroom Taskforce sought out additional restroom facilities to compensate for those that had been closed. They also procured and located portable restrooms. Additionally, the group’s maintenance team members began updating 21 restroom facilities, which include the first set of operator restrooms that were built, as well as more recently-built facilities.

This refresh consisted primarily of replacing worn or rusted electrical conduit and plumbing fixtures. Repairing or replacing the Instahot Instant Water Heater was also a top priority because handwashing is essential to safety and hygiene. Paper towel dispensers are also being replaced with electric hand dryers in all of our operator restrooms.

Main and Mission Restroom Refresh October 2020

Powell Station Staff Restroom Refresh August 2020

The team also built a restroom trailer to support the 30 Stockton bus route to Crissy Field.

By providing reliable restroom access, the SFMTA is working to meet the health and safety needs of our transit operators and other agency field staff, an often-overlooked aspect of improving Muni’s reliability.

Show HN: Browser Extension to make a language test out of any website https://ift.tt/2ZQ0v5e

Show HN: Browser Extension to make a language test out of any website I was preparing to German C1 recently and my vocabulary was the bottleneck. I didn't want to read boring materials and do boring exercises. Instead I noticed that there are sites in German, which I naturally enjoy. So I just made an extension to make language tests out of them. The approach is the following: 1) Open an interesting webpage in your target language. 2) Select text. 3) The extension replaces some words with gaps. 4) Read the text, fill in the gaps. Obviously just typing random words out of the blue can be overwhelming, so there is a mode to drag&drop words from a list into the correct places. I personally see this as active reading. My brain not only consumes information, but always try to guess the word from the context. I suspect that this helps with active vocabulary (i.e. to actually use the new words in writing). In the end I passed C1 exam (obviously I did other preparations too, not only this extension). This is a beta version for now and it is 100% free: Chrome: https://ift.tt/3swC3SN Firefox: https://ift.tt/2ZMgXDh If you didn't enjoy my explanation skills, there is an example video here: https://ift.tt/2OYXUUk I would love to hear whether you find this useful and your ideas how I could improve it. I might add payed features eventually to help developing the extension further, but I don't know a good mechanism to do this. I understand that 1$ in the US is very different from 1$ in e.g. India. I want this extension to bring value to everyone independently of their location and financial state. My current plan is to have the base version (i.e. like now) always free, since this already provides majority of value. Curious to hear your thoughts. February 25, 2021 at 02:11PM

Gene Henderson: Honoring Muni’s First Black Division Manager

Gene Henderson: Honoring Muni’s First Black Division Manager
By Jeremy Menzies

In recognition of Black History Month, we bring you the story of Gene Henderson, the first Black man to become the head of a Muni bus division, Muni’s Kirkland Division.

Henderson’s Background

Gene Henderson was born in Houston, Texas, in 1916. He married his wife Naomi in 1939 and then served in the U.S. Army during World War II. Following the war, Gene and his family moved to San Francisco where he began his career at the San Francisco Municipal Railway.

Early Career

On February 1, 1946, Henderson was hired as a streetcar motorman out of Sutro Division, which was located on the corner of 32nd Ave. and Clement St. He was hired just five years after Muni’s first Black transit operator, Audley Cole, had successfully fought to integrate the carmen’s union in 1941. In his early days at Muni, Gene worked one of the three lines running out of Sutro Division from the Ferry Building to the Richmond District on Sutter Street.

Five years into his career at Muni, Henderson moved to Kirkland Division as a bus driver and was nominated by passenger commendations for the Muni "Man of the Month" award, a recognition given to operators demonstrating excellence in their work.

Moving Through the Ranks

Gene Henderson’s career was marked by a series of new assignments and promotional advancements within the organization. Moving from motorman to bus driver, line trainer, inspector, dispatcher and claims investigator before becoming superintendent, Henderson gained the skills and knowledge he needed to run a busy operating division first-hand.  He was appointed head of Kirkland Division in 1973.  In the June-July 1973 issue of Muni’s Trolley Topics newsletter, it was reported that on his first day in the position, he treated Kirkland operators to doughnuts and coffee along with a bit of advice from his years of experience.

Gene Henderson (seated, fourth from the left) is pictured here with Muni's Claims Department staff in 1979, just one year before his retirement.

Late Career and Retirement

After three years as head of Kirkland, Henderson was on the move again, transferring to Assistant Claims Agent in 1976. Shortly thereafter, he became Safety and Training Supervisor in 1977, overseeing operator training and safety programs. In 1980, Henderson retired from Muni after over 34 years of service.  In the Trolley Topics newsletter article from the time, Henderson noted, "I've given it my best shot."  An understatement for a man who began as a streetcar operator and ended up as an important contributor to Muni's operations management.  Henderson passed away in 1999 at the age of 83.

For more stories of Muni’s unsung heroes and others who helped break down barriers in San Francisco transit, check out this article from Muni preservation partner, Market Street Railway and our past blog on the topic.

Youth Voices for Vision Zero SF

Youth Voices for Vision Zero SF
By Christine Osorio

Starting in the month of February, Muni buses and transit shelters will feature youth artwork illustrating Vision Zero traffic safety messages. The students are part of Youth Art Exchange (YAX), an arts-education non-profit based whose mission is to support San Francisco’s public high school students in becoming leaders, thinkers, and artists by sharing creative practices with professional artists. As part of Supervisor Norman Yee’s District 7 participatory budget process, YAX students consulted with SFMTA staff to develop traffic safety messages and artwork that reflect their experiences around traffic safety.

Themes highlighted through Youth Voices for Vision Zero SF include general traffic safety such as:

• Yielding to pedestrians in the crosswalk.
• Slowing down.
• Understanding that traffic deaths are preventable.
• Watching for people biking.
• Not blocking the sidewalk with a scooter.

The student artwork also included Covid-specific safety messaging to wear a mask while riding Muni.

Using street signs as inspiration, the students worked with mediums including hand-carved block prints, cyanotype (a printing process that uses light to create a cyan blue color, while areas that do not receive light remain white), and digital illustrations to create the final compositions.

YAX focuses on serving youth of color and low-income youth, and is rooted in the Excelsior neighborhood, which has a high concentration of high schools and the largest population of teenagers in the city. Because [x]space (Youth Art Exchange’s public arts hub) is within walking distance of high schools, and many of the students walk, bike and take Muni to [x]space to attend after-school programs, the students are uniquely positioned to speak about their experiences and insights regarding walking and biking.

Given the limitations of after-school program closures due to Covid-19, Youth Art Exchange closed its in-person activities and pivoted to digital programming in 2020. Youth artists worked remotely and collaboratively, meeting weekly to develop and design this body of artwork around the theme of traffic safety.

Launch HN: GreaseBoss (YC W21) – Real-time system to manage industrial greasing https://ift.tt/2NolF7X

Launch HN: GreaseBoss (YC W21) – Real-time system to manage industrial greasing We are Steve, Tim and Pete, the cofounders of GreaseBoss ( https://ift.tt/37CHvva ). GreaseBoss is a hardware and software system that verifies that the greasing of industrial equipment is completed on time and according to specification. Greasing, you say? Yup, you heard that right. Incorrect greasing is the number one cause for machinery failure on industrial sites. Industrial machinery failure costs the global economy $21B a year. Greasing is a big deal! We know this is an unsexy part of the economy, so we won’t judge you if you have never heard of a zerk (grease point) before. Some of our favourite places you can find zerks include super yachts - 200 zerks, private planes - 80 zerks, breweries - 2000 zerks, theme parks - 1500 zerks. Other places with lots of zerks include factories, mines, utilities, farm equipment, trucks and military vehicles. The idea for GreaseBoss came when Steve and Tim saw frequent machine breakdowns due to incorrect greasing while supporting mine sites in Outback Australia. This problem costs Australian mine sites hundreds of millions of dollars in lost productivity every year - disrupted production, spending on parts and labour for repairs. We built and tested our prototypes during the pandemic lockdowns on the back deck, over Zoom calls. We have now developed our MVP and have quit our jobs to chase GreaseBoss full time. On the hardware side: we put RFID tags that fit like washers under each zerk. These are read by a head unit that is retrofittable to existing grease guns, which includes a custom RFID reader integrated into the nozzle. It also includes a flow meter and supporting electronics. Our device has 4G, Wifi and LoRa for comms, but also operates in an offline mode for customers in remote locations. Our hardware is rugged, dust proof, and water proof for some of the toughest operational environments (and operators..) On the software side, we record each greasing in the cloud, right as the worker greases the zerk. Since most industry is still tracking this using paperwork, you can imagine how much more efficient this is. Our customers get back to production much faster. We are building a HaaS (Hardware as a Service - is that a thing?) business model: we charge customers upfront for the hardware and then a software subscription fee. We are experimenting with per zerk, per machine and per site pricing. We haven’t found the sweet spot yet. We have GreaseBoss installed at a large coal mine, a quarry and on excavators at the dump in Queensland, Australia. We also have a South African greasing contractor using our system. We will be online for the rest of the day answering your questions (we are in AEST timezone). We are very excited to receive your ideas, experiences and feedback! February 23, 2021 at 11:41PM

Show HN: Recollec – Faster and Easier Remote Employee Onboardings https://ift.tt/2ZK3M5S

Show HN: Recollec – Faster and Easier Remote Employee Onboardings Hey Everyone, My name is Firat, I’m the co-founder of Recollec [https://recollec.com]. It’s a collaborative workspace for employee onboarding and upskilling. More and more companies announcing that they are going all remote. Given the conditions, we realized how hard it is to make employee onboarding training. It usually happens in the endless zoom calls, back and forth... Yet, most of these calls can be archived for another onboarding. Also, there are thousands of free content out there which you can redirect your employees to learn by themselves. So we build Recollec which is a collaborative workspace where every employee can share most useful content from various resources in one feed, and turn them into learning paths to create interactive onboarding experiences. To be honest, I was hoping to find some folks who have a problem with the employee onboarding process at their work. I really could use some help and feedback right now. I know your time is valuable, and I absolutely don’t want to waste it. So, maybe we could find a way to create a tailor made solution for your onboarding process at work, and save some time for you. Here’s our demo: https://ift.tt/3qMcNqY You can reach me out at firat@recollec.com Thanks everyone February 23, 2021 at 11:40PM

Launch HN: Abacum (YC W21) – Easy collaboration and reporting for finance teams https://ift.tt/3pKswpd

Launch HN: Abacum (YC W21) – Easy collaboration and reporting for finance teams Hi HN! We're Jorge and Julio, cofounders of Abacum ( https://www.abacum.io/ ). We're not sure how many fintech geeks like us are on HN but we're very excited to launch to you guys anyway! Abacum makes it easier for Finance teams to access real-time data, collaborate and generate reports. Think of having all the operational and financial data modeled in one place, and of the Finance team easily sharing and collecting information for other teams to make faster, better decisions. Scale ups have unique finance needs. First, they have spent the last years growing unnaturally fast, held together by a mixture of google sheets, csv files, a disconnected tech stack and a lot of copy paste. Second, growing 4x a year means that historical data is out of date within 3 months. Finally, with so many channels to stay connected, it's impossible to find where the Tech Lead shared that key assumption for the board forecast. Both Jorge and I have lived these experiences - we've spent too many long nights and days in number-crunching, without the proper time to analyze the data and to provide insights, becoming the key business partner we wanted. So yes, in the middle of the lockdown with 3 children each decided to leave everything to build the product we wish we had! Abacum can now connect to any data source, update a business plan automatically and give you finance specific tools to help you do what you need to. Think performance and pivot tables, cohort and waterfall graphs, and ways to easily collaborate. Our engine provides the flexibility of excel while minimizing human errors, reducing fears of breaking "the model" and scaling up to and past IPO size. We're big believers that collaboration, and not the business model, needs to be placed at the center of the product. Everything we built in Abacum is easily shareable and built to be easily understood by non-finance professionals. Ask (or remind) others in your company to collaborate, be it for updating forecasts or commenting on reporting decks, right where the needed context is. We've also set up different workflows for customers to easily gather the data bottom-up from different teams. We are constantly looking to improve Abacum, so we'd love to hear any feedback, questions or wisdom you have to share with us! We'd love to show you (or anybody that you think may be interested) a 10' demo of our product - please let us know and we'll reach out. Thanks so much, HN! February 23, 2021 at 06:50PM

Launch HN: Wyndly (YC W21) – Allergy relief through at-home oral drops https://ift.tt/3aGtONC

Launch HN: Wyndly (YC W21) – Allergy relief through at-home oral drops Hi HN, I’m Aakash, and I’m a long time HN reader. My cousin Manan and I are excited to share our startup Wyndly ( https://www.wyndly.com ) with HN today. Wyndly is focused on making long-term allergy relief convenient through at-home allergy immunotherapy drops and telemedicine. These personalized oral drops train your immune systems to stop reacting to allergy triggers like pollen, pets, or dust. Manan is an ear-nose-and-throat surgeon and allergy doctor, and in his physical practice, he’s treated thousands of patients with at-home allergy drops, a form of allergy immunotherapy. During allergy immunotherapy, you gradually introduce your immune system to your allergy triggers. Over time, your immune system learns to tolerate these allergy triggers and stops reacting to them. For patients, this means greatly reduced allergy symptoms and long-term relief [1] without any other medicine for years after patients finish their immunotherapy. While allergy drops are 80% of allergy immunotherapy in some European countries, in the United States, allergy drops are just 5.9% of allergy immunotherapy prescriptions [2] and are really only available in university hospitals like Johns Hopkins, University of Pittsburgh, and West Virginia University [3] [4] [5]. Part of the reason for their limited availability is physician training, and another part is the health insurance system’s incentives. Most allergy doctors were trained on allergy shots, and prescribe what they are most experienced with. Additionally, health insurance programs incentivize prescribing allergy shots. In his medical training, Manan trained on both allergy drops and shots. When Manan gave his patients the choice between at-home allergy drops and allergy shots, his patients always chose drops, which are safer, convenient, and don’t require needles [6]. When Covid-19 hit Denver in March 2020, Manan switched all of his allergy drop patients to online care to continue treatment. After shelter-in-place was lifted, his patients continued online care due to the convenience, which told us one thing—patients preferred and were comfortable with telemedicine for allergy care. And that's why we started Wyndly. We’re trying to make allergy immunotherapy convenient and affordable, so that any one of the 60 million people in America suffering from allergies has the opportunity to get lifelong relief—just like braces straighten your teeth and Lasik fixes your vision. We’ve done our best to make our patient experience as easy as possible. First, we learn more about you and your allergy history. Then, our medical team creates a personalized treatment plan with treatment sent straight to your door. Most patients notice benefits at 6 months, and some patients have reported allergy symptom relief as early as 6 weeks [7]. Patients lock-in lifelong allergy relief after a few years [1]. Throughout this time, we stay in touch with the patient to work with them towards allergy relief. Please let us know if you have more questions or feedback. We love talking about the science behind allergy immunotherapy, our treatment model, and what we’re doing. We're happy to answer any questions!

Launch HN: H3X (YC W21) – High power density electric aircraft motors https://ift.tt/3qERuaO

Launch HN: H3X (YC W21) – High power density electric aircraft motors Hey HN! I’m Jason, one of the co-founders at H3X ( https://www.h3x.tech ). We are building the lightest electric propulsion systems in the world. Our first product is a 250kW (330HP) integrated motor drive in a 18kg (40lb) package. It combines the electric motor, inverter, and gearbox into a single unit, resulting in an ultra-high-power density solution for electric aircraft (and other mass sensitive applications). In terms of electrification, we believe the aircraft industry is where automotive was ten years ago. There are many companies working on eVTOL and single-seaters, but very few are working on large commercial single-aisle electric aircraft such as a 737. This class of aircraft is absolutely critical to electrify as it accounts for the most passenger-miles [1] and is the biggest slice of the pie in terms of aviation emissions. Beyond the environmental impact, there are huge potential cost savings from both fuel (or lack thereof) and reduced maintenance for airlines. Aircraft are very mass sensitive so there are two main technology challenges that need to be solved to enable this class of electric aviation – (1) High energy density and efficient energy storage (batteries, hydrogen fuel cells, etc.) (2) Light, efficient, and high-power density electric propulsion systems (electric motors, power electronics, gearbox) There are many people working on (1) and great strides are being made [2][3]. We are focused on solving (2). A study done by the DOE determined that for a 737 to complete a five-hour flight, the propulsion system must be >12 kW/kg [4]. Today, best-in-class systems have a power density of 3-4 kW/kg. With our first product, we are targeting 13 kW/kg, making it an attractive solution for near-term Advanced Air Mobility (AAM) applications as well as an enabling technology for the aviation industry to enter the next stage of electrification. There are some cool things we are doing with the electromagnetics, power electronics, and the integration between the systems to get to the 13 kW/kg. There is not a single magic bullet, but rather a combination of multiple technological advances - 3D printed copper stator coils, high frequency SiC power electronics, and a synergistic cooling system to name a few. Our origins in electrification stem back to our college days where we built Formula-style electric racecars (s/o to Wisconsin Racing FSAE!). During year 1 of the program, we got so fed up with our COTS motors and inverters, we decided to go clean slate and build our own from the ground up the following year. Those were super happy fun times. Lots of dead IGBTs and all-nighters in the shop, but in the end, we got everything working and delivered! It was a true test of resilience and taught us how to GSD. Great preparation for starting a company. This led us to grad school and it became apparent during this time that the electric aircraft industry was a sleeping giant ready to be woken. We felt uniquely positioned to capitalize on this opportunity, so after about a year in industry, we left our full-time jobs and went all in. We’ve got a long road ahead - aviation is tough, there’s no denying that. In addition to the engineering challenges, there are also major certification barriers. However, CO2 is a serious problem and right now the major aviation players don’t have a compelling plan to meet the goals laid out in the Paris Agreement. Innovation needs to come from the outside and that’s what we’re doing at H3X. I’d love to hear your guys thoughts and would be happy to answer any questions you have.

Show HN: Peppa PEG – An Ultra Lightweight PEG Parser in ANSI C After reading the [PEG Parsers series] written by Guido van Rossum, I started thinking writing a PEG Parser in ANSI C. Here are the reasons: - It's FUN. I've made several parser libraries, such as JSON, Mustache, Markdown, and I think I can take the challenge now. - I haven't had any opportunity to work on an Open Source project written in ANSI C. - Having a PEG parser in ANSI C can benefit whoever is developing a parser, as adding C bindings for other programming languages are not too difficult. And after SIX months' development, my project is now kinda feature complete. It's named Peppa PEG and you can find it here: https://ift.tt/3aBmrqW I have learned quite a lot during the journey of creating it, such as gdb, valgrind, cmake, etc. And I wouldn't make it to the end without learning from some awesome projects, such as pest.rs, cJSON, etc. Appreciate any feedbacks!

Free Muni and Paratransit to COVID-19 Vaccine Appointments

Free Muni and Paratransit to COVID-19 Vaccine Appointments
By Phillip Pierce

Free Muni and Paratransit to COVID-19 Vaccine Appointments

Starting on Tuesday, February 23, Muni and Paratransit will be free for those traveling to get vaccinated for COVID-19. This includes trips in both directions. The SFMTA is also providing additional access to taxi service for those who use the Essential Trip Card.

These rides are good for trips to the city-sponsored high-volume vaccine sites, hospitals or anywhere else that is offering vaccines. More information on the city-sponsored sites as well as directions on how to get there can be found on the city vaccination website.

We know that getting San Franciscans vaccinated is the city’s highest priority. This program is designed to eliminate transportation and cost barriers to receiving this life-changing vaccine.

How to Ride on Muni

Use our trip planner or service map to find the best way to get to your vaccination destination. Simply catch the bus and head to where you need to go. Please have your vaccine appointment confirmation or instructions ready in case SFMTA staff asks to see your proof of payment.

Paratransit

Paratransit rides on SF Access van service to and from vaccination appointments will be free for eligible participants. Paratransit van riders must call to make a trip reservation and indicate that they are going to get their COVID-19 vaccine. Staff will make a note in their records to alert the driver that the rider does not need to pay a fare for their trip.

Paratransit taxi riders will have $60 loaded onto their taxi debit card, which will be valid for up to six months, to get to and from their vaccine appointment. Funds should be available starting next week. If you are a paratransit taxi rider and have a question about the value on your card or want to confirm if the additional value has been added, you may call 415.351.7000 or check your card’s transaction history on the SF Paratransit Taxi online portal. 

More information can be found on the SFMTA Paratransit website.

Essential Trip Card

The Essential Trip Card (ETC) already subsidizes about two to three round trips by taxi per month for older adults (persons 65 and older) and people with disabilities. Eligible participants pay 20% of the taxi fare for essential taxi trips. To pay, each rider is issued an ETC debit card, which they can load with value every month.  If ETC participants think that the cost of their trips to vaccine appointments will require more funds than they can currently load each month, they can add $60 of additional funds, at the cost of $12 to the rider, one time only. Existing ETC customers can add this new value on-line, by phone or by mail, same as usual. New applicants can sign-up by calling 311.

Launch HN: MindsDB (YC W20) – Machine Learning Inside Your Database https://ift.tt/2ZuqrTN

Launch HN: MindsDB (YC W20) – Machine Learning Inside Your Database Hi HN, Adam and Jorge here, and today we’re very excited to share MindsDB with you ( https://ift.tt/2UJWtY6 ). MindsDB AutoML Server is an open-source platform designed to accelerate machine learning workflows for people with data inside databases by introducing virtual AI tables. We allow you to create and consume machine learning models as regular database tables. Jorge and I have been friends for many years, having first met at college. We have previously founded and failed at another startup, but we stuck together as a team to start MindsDB. Initially a passion project, MindsDB began as an idea to help those who could not afford to hire a team of data scientists, which at the time was (and still is) very expensive. It has since grown into a thriving open-source community with contributors and users all over the globe. With the plethora of data available in databases today, predictive modeling can often be a pain, especially if you need to write complex applications for ingesting data, training encoders and embedders, writing sampling algorithms, training models, optimizing, scheduling, versioning, moving models into production environments, maintaining them and then having to explain the predictions and the degree of confidence… we knew there had to be a better way! We aim to steer you away from constantly reinventing the wheel by abstracting most of the unnecessary complexities around building, training, and deploying machine learning models. MindsDB provides you with two techniques for this: build and train models as simply as you would write an SQL query, and seamlessly “publish” and manage machine learning models as virtual tables inside your databases (we support Clickhouse, MariaDB, MySQL, PostgreSQL, and MSSQL. MongoDB is coming soon.) We also support getting data from other sources, such as Snowflake, s3, SQLite, and any excel, JSON, or CSV file. When we talk to our growing community, we find that they are using MindsDB for anything ranging from reducing financial risk in the payments sector to predicting in-app usage statistics - one user is even trying to predict the price of Bitcoin using sentiment analysis (we wish them luck). No matter what the use-case, what we hear most often is that the two most painful parts of the whole process are model generation (R&D) and/or moving the model into production. For those who already have models (i.e. who have already done the R&D part), we are launching the ability to bring your own models from frameworks like Pytorch, Tensorflow, scikit-learn, Keras, XGBoost, CatBoost, LightGBM, etc. directly into your database. If you’d like to try this experimental feature, you can sign-up here: ( https://ift.tt/3uhw05U ) We currently have a handful of customers who pay us for support. However, we will soon be launching a cloud version of MindsDB for those who do not want to worry about DevOps, scalability, and managing GPU clusters. Nevertheless, MindsDB will always remain free and open-source, because democratizing machine learning is at the core of every decision we make. We’re making good progress thanks to our open-source community and are also grateful to have the backing of the founders of MySQL & MariaDB. We would love your feedback and invite you to try it out. We’d also love to hear about your experience, so please share your feedback, thoughts, comments, and ideas below. https://ift.tt/3k6zsfm or https://mindsdb.com/ Thanks in advance, Adam & Jorge February 19, 2021 at 10:25PM

Launch HN: HiGeorge (YC W21) – Real-time data visualizations for public datasets https://ift.tt/2NGzfTM

Launch HN: HiGeorge (YC W21) – Real-time data visualizations for public datasets Hi HN! Anuj here. My co-founder Amir (Aazo11) and I are building HiGeorge ( https://hi-george.com/ ). We make localized drag-and-drop data visualizations so that all publishers, even the small ones, can better leverage data in their storytelling. Think Tableau with all the necessary data attached. At the onset of the pandemic Amir and I were looking for local data on the spread of the virus. We visited the sites of large national newsrooms like the NYTimes and were impressed by the quality of data visualizations and maps, but they lacked the geographic granularity for our own neighborhood. We then turned to our local newsrooms but found they presented data in tables and lists that made it difficult to comprehend the virus’ spread and trends. We wondered why. After talking to local journalists and publishers, we found that newsrooms simply do not have the resources to make sense of large datasets. Public datasets are hard to clean, poorly structured, and constantly updated. One publisher explained to us that she would refresh her state health department’s website 5 times a day waiting for updated COVID data, then manually download a CSV and clean it in Excel. This process could take hours, and it needed to happen every day. This is where HiGeorge comes in. We clean and aggregate public datasets and turn them into auto-updating data visualizations that anyone can instantly use with a simple copy/paste. Our data visualizations can be drag-and-dropped into articles, allowing news publishers to offer compelling data content to their communities. Check out a few versions of what we’re doing with customers -- COVID-19 data reporting at North Carolina Health News [1], COVID-19 vaccine site mapping at SFGATE [2], real-time crime reporting in Dallas, TX [3], and police use of force at Mission Local [4]. Today, HiGeorge works with dozens of newsrooms across the country. Our visualizations have driven a 2x increase in pageviews and a 75% increase in session duration for our partner publishers. We charge a monthly subscription for access to our data visualization library – a fraction of the cost of an in-house data engineer. In the long run, we are building HiGeorge so that it becomes the single place to collaborate on and publish data content. We’d love to hear from the HN community and we’ll be hanging out in the comments if you have any questions or feedback. [1] https://ift.tt/3k10ZPa... [2] https://ift.tt/3k8D6oL...

Virtual Parade and New Central Subway Art Ring in Lunar New Year

Virtual Parade and New Central Subway Art Ring in Lunar New Year
By Sophia Scherr

We are entering the year of the Ox, typically symbolizing hard work, positivity, and honesty. This year the SFMTA will continue the tradition of celebration with the virtual San Francisco Chinese New Year Parade  on February 20th at 6 pm on KTVU.

Celebrating Lunar New Year and the San Francisco Chinese community has been a long-standing tradition for many of us. In 1849, San Francisco’s population swelled to 50,000 and many of the new residents were Chinese immigrants, coming to work in gold mines or on railroad lines. By the 1860’s, the Chinese were eager to share their culture with others and the annual tradition of parade and pageantry was born. A variety of other cultural groups throughout the city were invited to participate, and they marched down what today are Grant Avenue and Kearny Street with colorful flags, banners, lanterns, and drums and firecrackers to drive away evil spirits. The city’s Chinese New Year Parade is one of the largest celebrations of its kind in the world, attracting over three million spectators and television viewers throughout the U.S., Canada and Asia.

In line with what the year of the Ox signifies, we also look forward to seeing our work come to fruition when the Central Subway Project's Chinatown - Rose Pak station opens in 2022. As part of this milestone, the SFMTA in partnership with SFAC’s Public Art Program, the Chinese Culture Center, Chinatown Community Development Center, and the Chinese Historical Society have envisioned a vibrant art program for Chinatown’s station. Three significant prominent artworks by artists Tomie Arai, Yumie Hou and Clare Rojas are being installed, infusing the quintessential Chinatown spirit into their works, connecting the past, present and future. These artworks also serve as wayfinding – from marking the entrance to the station, to signaling to riders their arrival at Chinatown with placement of prominent works on the platform walls.

Traditional Chinese paper cut artist Yumei Hou developed large murals that will adorn the station

Ongoing community involvement is an essential to ensuring that Chinatown residents had a role in the artwork design process. The Chinese Cultural Center helped convene community meetings so that the artists would be able to meet residents and receive feedback on their proposed designs. Through this support, artists and community members were able to collaborate on the design of the installations. Artist Tomie Arai was able to work with local photographer Bob Hsiang to photograph students from Gordon J. Lau Elementary School who were then featured in her work.

Central Subway Project outreach staff and their partners at the Chinatown Community Development Center wanted to ensure that all aspects of Chinese culture and art were represented in the art program that will adorn the entryway of the stations roof-top plaza. The center conducted a couplet contest that garnered 120 couplet entries from local, national and international poets. San Francisco poet, Carin Mui was selected, her couplet, a form of Chinese poetry with two lines of verse that have a joined meaning and follow a list of exacting rules reads “In the past, we traveled across the Pacific to mine for gold; Now, we break through earth to form a silver dragon.”

Artist Terry Luk paints the winning couplet for the Chinatown Central Subway Station, as composer Carin Mui, former Chinatown Community Development Center staffer Jerri Diep and former Central Subway Program Manager John Funghi look on.

The winning couplet was recently installed in the public plaza above the Chinatown – Rose Pak Station

Public art in our stations is important not only for its aesthetic or beauty, but helps draw out the identity of a space, aids in the understanding of the historic or cultural significance of a neighborhood and builds a connection between visitor and the surrounding community. It’s an important reminder of the power of art to address the complexity and diversity of neighborhoods and to maintain cultural identity in the face of rapid urban transformation.

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM https://ift.tt/3s2MTj0

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM Hi YC! We are Santiago Aparicio, Julian Torres and Jaime Abella and we are from Colombia. We are building Ontop (www.ontop.ai) to help companies do remote hiring and payouts, all the way from contract creation, to compliance documentation and easy money transfers. COVID-19 has taught us all that remote works. Our bet is that companies in the US and Europe will start hiring more people in LATAM because talent is increasing in quality at a fraction of price compared to what they can get elsewhere. Paying people in LATAM requires local knowledge to get the level of speed and compliance that workers need to get their money on time. We are building a solution so companies hiring in LATAM have to do less paperwork, can easily be compliant and disperse payments to different countries in a single place. In our previous startup Fitpal (multi gym membership in LATAM) we experienced the pain behind signing contracts, collecting documents and sending money to different countries. We had to pay hundreds of gyms in LATAM and were frustrated by the amount of time we spent doing administrative work, when we should have been thinking on how to hack our way to growth. We handle all paperwork, compliance and payments so onboarding new people is really easy. And most importantly, everything done legally, by the book, so that companies are always due diligence proof. Our solution is tailored for LATAM guaranteeing the best speed and compliance in the market. We want to hear your thoughts on our solution. We value feedback and case uses that you might have. Email us at founders@ontop.ai and we will personally give you a demo. February 18, 2021 at 06:28PM

Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech https://ift.tt/3beSuvY

Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech Hey everyone, we're Anton (avais), Kirill (Datkiri), and Volodymyr (vsofi), the founders of Datrics ( https://datrics.ai ). We help FinTech companies build and deploy machine learning models without writing code. We provide a visual tool to work with structured data by constructing a diagram of data manipulations from lego-like bricks, and then execute it all on a backend. This lets our users accomplish tasks that usually need a team of software engineers, data scientists, and DevOps. For instance, one of our customers is a consumer lending company that developed a new risk model using just our drag-and-drop interface. I used to lead a large data science consultancy team, being responsible for Financial Services (and Risks specifically). Our teams’ projects included end-to-end risk modeling, demand forecasting, and inventory management optimization, mostly requiring combined efforts from different technical teams and business units to be implemented. It usually took months of work to turn an idea into a complete solution, going through data snapshot gathering to cleansing to experimenting to working with engineering and DevOps teams to turn experiments in Jupyter notebooks into a complete application that worked in production. Moreover, even if the application and logic behind the scenes were really simple (could be just dozens or hundreds of lines of code for a core part), the process to bring this to end-users could take ages. We started thinking about possible solutions when a request from one of the Tier 1 banks appeared, which confirmed that we’re not alone in this vision: their problem was giving their “citizen data scientists” and “citizen developers” power to do data-driven work. In other words, work with the data and generate insights useful for business. That was the first time I’d heard the term “citizen data scientist”. Our users are now these citizen data scientists and developers, whom we’re giving the possibility to manipulate data, build apps, pipelines, and ML models with just nominal IT support. Datrics is designed not only to do ML without coding, but to give analysts and domain experts a drag and drop interface to perform queries, generate reports, and do forecasting in a visual way with nominal IT support. One of our core use cases is doing better credit risk modeling - create application scorecards based on ML or apply rule-based transactional fraud detection. For this use-case, we’ve developed intelligent bricks that allow you to do variables binning and scorecards in a visual way. Other use cases include reports and pivot tables on aggregating sales data from different countries in different formats or doing inventory optimization by forecasting the demand without knowing any programming language. We’re providing 50+ bricks to construct ETL pipelines and build models. There are some limitations - a finite number of pre-built building blocks that can be included in your app, but if there is no block that you need, you can easily build your own ( https://youtu.be/BQNFcZWwUC8 ). Datrics is initially cloud-native, but also can be installed on-prem for those customers who have corresponding security policy or setups. The underlying technology, the pipeline execution engine is rather complex and currently built on top of Dask, which gives Python scalability for big datasets. In the next release, we are going to support Pandas as well as to switch intelligently between small datasets for rapid prototyping and big datasets for pipeline deployments. We’re charging only for private deployments, so our web version is free: https://ift.tt/2Nfu1i1 . Try it to create your analytical applications with a machine learning component! We've put together a wiki ( https://wiki.datrics.ai ) to cover the major functionality, We are super-excited to hear your thoughts and feedback! We're big believers in the power of Machine Learning and self-service analytics and are happy to discuss what you think of no-code approaches for doing ML and analytics generally as well as the availability of them for non-data scientists. Or anything you want to share in this space! February 18, 2021 at 01:42PM

More Muni Metro Rail to Return in May

More Muni Metro Rail to Return in May
By Mariana Maguire

By May, the SFMTA plans to restart more Muni Metro rail service, extending the T Third Metro rail route between Sunnydale and West Portal, and bringing the full N Judah Metro rail route back into service between 4th and King (CalTrain) and La Playa (Ocean Beach).

Adding Metro rail service means we can connect more customers to essential jobs and locations along these routes and make it easier for customers to travel through downtown along Market Street.

Since August 2020, Muni has been undertaking intensive subway repairs after discovering some potentially faulty overhead splices and issues with ballast in the Eureka Curve/Twin Peaks Tunnel. We are now moving closer to completing the essential repairs and upgrades which will allow us to reopen subway service. Our work crews have removed all of the splices that had been potentially defective and replaced them with splices from a new manufacturer. We’ve also finished construction of the ballast in the Eureka Curve and have begun extensive testing and certification of the subway to ensure that everything works properly, reliably and safely. In the meantime, we’re also continuing important regular maintenance work to make as many improvements as possible while the subway is temporarily closed.

The return of the N Judah Metro rail will also free up buses that we will put to use on existing bus routes so that we can circulate other vehicles out for critical maintenance. In the effort to bring back as much bus service as possible and run buses more frequently, we have been pushing our vehicles to the limits with little or no time for maintenance. The additional buses released from N Judah service will allow us to maintain existing bus service while also keeping our fleet in good working order.

The SFMTA continues to work closely with district supervisors, stakeholders and community members to bring back additional service and modify existing service to better balance our available resources with our customers’ needs. This is especially a priority for communities most dependent on transit and who have the fewest alternative transportation options for essential travel.

We will continue to provide updates with more details and a complete list of service changes as information is available.

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces https://ift.tt/3s2IAnT

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces Hey HN, Aakhil, Theresa & Mark here at Worksphere (https://worksphere.com). Our software helps companies manage a safe workplace where employees can work flexibly in-office or remote. Worksphere automates desk reservations, safe entry, and gives companies office usage data to right-size their workplaces. We previously worked together at Lish, a corporate catering marketplace startup catering (pun intended) to tech companies. Last March our revenue went off a cliff. No people in office = no lunch orders. We love our clients and our team, so we got to work on solving a new problem for our primary users - HR, Office, and Facilities Managers. At the start of the pandemic, our users were struggling with how to return to their offices safely. New problems like enforcing social distancing, screening for COVID-19 symptoms, and contact tracing could not be solved at scale with existing tools. New coronavirus workplace regulations have cropped up, which are a pain and come with big financial risk if companies don’t comply (we’re looking at you CA businesses dealing with SB 1159 & AB 685 - learn more at https://ift.tt/2ZDAx4V). As the pandemic has continued (and continued, and continued) businesses are facing a new challenge. 75% of office employees report that they want a hybrid in-office and remote schedule. No one misses their 5-day-a-week commute. At the same time, collaboration and culture are hard to foster on Zoom and Slack alone. Employees still want access to an office when needed, but don’t want to come to work in an empty space. Businesses want the upsides of flexibility, but don’t want to pay for empty or only occasionally used desks — office space costs $10-12k per employee annually in major US cities. We believe that a hybrid workweek is a better workweek, and that an active approach is needed to make it a win-win for employees and businesses. Our features help businesses reopen safely and realize the full potential of a flexible workplace. We automate the wellness surveys, contact tracing, and capacity limits needed to enforce internal safety guidelines and regional regulations. This alleviates a ton of manual work for Office and HR managers. Employees can create in-office schedules and see who else is in the office to increase collaboration. We track office utilization data so companies can make smart decisions about their office space and lease. Worksphere is $6 per active employee/month, and our clients only pay for employees that come to the office. If you’re one of the 3 of 4 people who wants to work flexibly post-pandemic, or if you manage a workplace, we’d love to hear from you. How frequently do you think you’ll need office space? What problems are you facing in this changing work environment? We’ll reply in the comments or you can email us at info@worksphere.com. Thanks so much for your feedback! February 17, 2021 at 09:36PM

Mask Up - It's the Law!

Mask Up - It's the Law!
By Kristen Holland

You may hear a new announcement on our vehicles or see new messages about masks being required by federal law. The spread of COVID-19 has led the federal government to enact a mask requirement for all public transportation conveyances. Here in San Francisco, that law means wearing a mask in Muni stations, when purchasing a ticket and while waiting for, boarding, riding or exiting transit. Failure to wear a mask can result in denial of boarding, removal from Muni and may carry federal penalties.

Muni customers are doing great when it comes to mask compliance, which consistently exceeds 95% (see chart). You get it. Wearing masks, physically distancing and riding Muni for only essential trips remain crucial to reducing the spread of COVID-19.

The SFMTA mask survey for the final week of January 2021 reported 97% compliance

And every week, our operators, fare inspectors and ambassadors hand out thousands of masks to those who don’t have one. Thank you for protecting our employees and each other.

During the first week of February 2021, the SFMTA distributed nearly 16,000 masks

Here’s more on the new law:

The federal mask requirement went into effect earlier this month and will continue until May 2021.

As a reminder, a properly worn mask:

• Completely covers the nose and mouth of the wearer
• Is secured to the head, including with ties or ear loops
• Fits snugly against the side of the face.

Face shields do not fulfill the requirements of the law. Instead, masks should be a solid piece of material without slits, exhalation valves, or punctures. Face coverings like scarves and bandanas do not meet this requirement. Visit the CDC website for tips on improving your mask to protect yourself and others.

Like other mask requirements, the law allows for some exemptions and exceptions. For example, the temporary removal of a mask is allowed in order to:

• Take oral medications for brief periods.
• Communicate with a person who is deaf or hard of hearing, when the ability to see the mouth is essential for communication.

The specifics of the federal law are outlined in the Transportation Security Administration Security Directive.

All state and local public health orders remain in effect.  For more information, visit SFMTA.com/COVID or call 311 within San Francisco or 415-701-4311. Free language assistance available.

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers https://ift.tt/37jqZjH

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers Hello HN! I'm Josh, one of the co-founders of Noya ( https://noyalabs.com ). Noya is designing a cheaper process to capture CO2 directly from the atmosphere. We do this by retrofitting industrial cooling towers owned and operated by other companies to perform carbon capture. We then sell the captured CO2 to companies that need it, and pay a piece of the proceeds to the companies that own the cooling towers. As the wildfires in California became worse and worse, my co-founder (and roommate at the time) Daniel and I became increasingly concerned that we weren't doing enough to be a part of the solution. The more that climate catastrophes became the norm, the more we became obsessed with one seemingly-simple question: If climate change is caused by having too much CO2 in the sky... can't we just reverse it by yanking CO2 out of the sky? Humans have known how to scrub CO2 out of gas mixtures for almost a century [1]; but, we haven't been able to widely apply this type of tech to scrubbing CO2 from the air because of its high cost. For example, one popular direct air capture project is estimated to capture 1M tons of CO2/year [2], but has an estimated equipment cost of $700M and all-in costs of ~$1.1B [3]. The single largest component of this cost is in the piece of equipment called the air contactor — the big wall of fans you see in the image linked above — which clocks in at $212M by itself. Yet fundamentally, all that air contactors do is put air into contact with something that captures CO2, whether it's an aqueous capture solution or some sort of solid sorbent. These costs felt astronomical to Daniel and I, so we set out with the singular focus to reduce the costs of carbon capture by reducing the costs of the air contactor. But no matter how we thought about it, we couldn’t get around the fact that to capture meaningful amounts of CO2, you need to move massive amounts of air since CO2 is very dilute in the atmosphere (0.04% by volume). Looking at the existing solutions, we began to understand why it makes sense to build something equally massive: so you can go after economies of scale. As Daniel and I were feeling stuck late one night, he got a call from his dad. They started talking about the refrigeration facility Daniel’s dad runs in Venezuela (where Daniel's from), and they started talking about the cooling towers at the facility. Cooling towers move air and water into contact with each other to provide cooling to industrial processes (descriptive video: https://www.youtube.com/watch?v=pXaK8_F8dn0 ). As Daniel listened to his dad, Daniel realized that if we could just add the blend of CO2-absorbing chemicals we had been developing into the water his dad’s cooling tower used, we could use it as an air contactor and achieve CO2 capture at the same time the cooling tower was cooling its processes. This eliminates the need to build millions of dollars worth of dedicated equipment to pluck CO2 from the sky. Our cooling-tower-based carbon capture process works as follows: we add our chemical carbon capture blend into a cooling tower's water, we connect the tower to some pieces of downstream processing equipment to regenerate the captured CO2, and then we pressurize the CO2 into cylinders for sale as "reclaimed CO2" to companies that need it. All of this is installed onto a cooling tower that another company already owns and operates. In exchange for letting us install this process on their towers, we will cover the cost of installation, and the companies will get a piece of the revenue generated through the sale of their CO2. We’re well on our way towards making this process a reality. We’ve partnered with a local farm to install our process in their cooling towers, and we've just produced CO2 using our industrial-scale prototype. We're excited for the opportunity to reverse climate change and ensure we have a future on this planet that is good. Please let us know what questions, concerns, or feedback you have about what we're building - I’ll be here all day! [1]: https://ift.tt/3u1lL5J [2]: https://ift.tt/2Zm55HY...

Launch HN: Pyroscope (YC W21) – Continuous profiling software https://ift.tt/2Zhzo2L

Launch HN: Pyroscope (YC W21) – Continuous profiling software Hi HN! Dmitry and Ryan here. We're building Pyroscope ( https://pyroscope.io/ ) — an open source continuous profiling platform ( https://ift.tt/2L1jeqC ). We started working on it a few months ago. I did a lot of profiling at my last job and I always thought that profiling tools provide a ton of value in terms of reducing latency and cutting cloud costs, but are very hard to use. With most of them you have to profile your programs locally on your machine. If you can profile in production, you often have to be very lucky to catch the issues happening live, you can't just go back in time with these tools. So I thought, why not just run some profiler 24/7 in production environment? I talked about this to my friend Ryan and we started working. One of the big concerns we heard from people early on was that profilers typically slow down your code, sometimes to the point that it's not suitable for production use at all. We solved this issue by using sampling profilers — those work by looking at the stacktrace X number of times per second instead of hooking into method calls and that makes profiling much less taxing on the CPU. The next big issue that came up was storage — if you simply get a bunch of profiles, gzip them and then store them on disk they will consume a lot of space very quickly, so much that it will become impractical and too expensive to do so. We spent a lot of energy trying to come up with a way of storing the data that would be efficient and fast to query. In the end we came up with a system that uses segment trees [1] for fast reads (basically each read becomes log(n)), and tries [2] for storing the symbols (same trick that's used to encode symbols in Mach-O file format for example). This is at least 10 times more efficient than just gzipping profiles. After we did all of this we ran some back of the envelope calculations and the results were really good — with this approach you can profile thousands of apps with 100Hz frequency and 10 second granularity for 1 year and it will only cost you about 1% of your existing cloud costs (CPU + RAM + Disk). E.g if you currently run 100 c5.large machines we estimate that you'll need just one more c5.large to store all that profiling data. Currently we have support for Go, Python and Ruby and the setup is usually just a few lines of code. We plan to release eBPF, Node and Java integrations soon. We also have a live demo with 1 year of profiling data collected from an example Python app https://ift.tt/3ajTu2z... And that's where we are right now. Our long term plan is to keep the core of the project open source, and provide the community with paid services like hosting and support. The hosted version is in the works and we aim to do a public release in about a month or so. Give it a try: https://ift.tt/2L1jeqC . We look forward to receiving your feedback on our work so far. Even better, we would love to hear about the ways people currently use profilers and how we can make the whole experience less frustrating and ultimately help everyone make their code faster and cut their cloud costs.

Show HN: Save 6 months to deploy your apps on AWS in 30 minutes https://ift.tt/2OC9NPU

Show HN: Save 6 months to deploy your apps on AWS in 30 minutes I am Romaric, CEO of Qovery (https://www.qovery.com) (Techstars Paris 2019). As an early-stage startup, I know how it can be painful to stay focus on our business. Especially when it comes to putting our apps online, that's precisely why, with my team of 7, we have created Qovery to help any company to deploy their apps on AWS in 30 minutes instead of months (no joke). We're still early stage, but: 1. More than 1200 developers and 10 companies are using Qovery . 2. We are financially backed by the co-founders of Datadog, Docker, PeopleDoc, and Contentsquare . Take a look at this article to see how you can get started ( https://ift.tt/3acBO7y ). Today, we support AWS and Digital Ocean, we expect to support GCP and Azure in the coming weeks. About the co-founders: Pierre and I (Romaric) were working as SRE for Ullink, Red-Hat, Criteo, Sirdata for 10 years. Basically, we always were helping developers to deploy their apps and keep being as productive as possible. Instead of doing it for the next successful company, we decided to launch Qovery in Oct 2019. We have fundraised $1M (Techcrunch article), and we have been accelerated by Techstars. Since then, 1200 developers are using Qovery to deploy their apps, we have build a team of 8 engineers, and we are still hiring :) Join us in making the Cloud simple again :) I am eager to hear from you.
