Launch HN: Hubble (YC S20) – Monitor data quality inside data warehouses Hey everyone! We’re Oliver and Hamzah from Hubble ( https://gethubble.io/hn ). Hubble runs tests on your data warehouse so you can identify issues with data quality. You can test for things like missing values, uniqueness of data or how frequently data is added/updated. We worked together for the last 4 years at a startup where we built and managed data products for insurers and banks. A common pattern we saw was teams taking data from their internal tools (CRM, HR system, etc.), application databases, and 3rd party data and storing it in a warehouse for analysis. However, when analysts/data scientists used the data for reports they would spot something suspicious and the engineering team would have to manually go through the data pipelines to find the source of the problem. More often than not it was simple things like a spike in missing values because an ETL job failed or stale data because a 3rd party data source hadn’t updated correctly. We realised that reliability/ trustworthiness of the raw data was essential before you could start abstracting away more interesting tasks like analysis, insight or predictions. We wanted to do this without having to write and maintain lots of individual tests in our code. So we built Hubble, which connects to a data warehouse and creates tests based on the type of data being stored (i.e. freshness of timestamps, the cardinality of strings, max value of numbers, missing values, etc.). We’ve also added the ability to write any custom tests using a built-in SQL editor. All the tests run on a schedule and you’ll get an email or slack alert when they fail. We’re also building webhooks and an Airflow operator so you can run tests immediately after running an ETL job or trigger a process to fix a failing test. Instead of asking users to send their data to us, the tests are run in the data warehouse and we track the test results over time. Today we support BigQuery, Snowflake and Rockset (which lets us work with MongoDB and DynamoDB) and are adding more on request. We’re planning on charging $200 a month for a few seats, and $30-50 for extra users after that. We’re still at an early access stage but want the HN community’s feedback so we’ve opened up access to the app for a few days, you can try it out here https://gethubble.io/hn . We’ve added a demo data warehouse you can start with that has data on COVID-19 cases in Italy and bike-share trips in San Francisco. Thanks and looking forward to hearing your ideas, experiences and feedback! August 20, 2020 at 10:38PM

Show HN: Wishlist – Collect and organize user feedback https://ift.tt/3aOzh3C

Show HN: Wishlist – Collect and organize user feedback As founders, we know how important it is to talk to our customers in order to avoid wasting time building features that no one wants. It can be difficult to know what to work on next, and how many resources to devote to a particular product or feature. That's why I've decided to build https://getwishlist.io, a (currently free in beta) user feedback tool that will help founders like ourselves not only collect user feedback, but also organize it, and build product roadmaps. As such, I'd love to speak with my fellow founders about how you collect feedback from your team and users, how you do your product roadmaps, and some of the challenges you face while doing so. How do you collect and organize feedback from your users? What are your processes? What don’t you like about them? Care to share? August 20, 2020 at 05:36PM

Show HN: My brother wrote this program from jail https://ift.tt/34i3y9E

Show HN: My brother wrote this program from jail Hi HN!, My brother got a 5 years jail sentence but is coming out soon, a few months ago he decided to learn to code with no prior experience. I find the way he is studying very inspirational so decided to post his (simple) program. But first, here is what he needs to go through to learn: - We the family send him javascript and html books - He studies them and writes programs in pen and paper - He calls me so I input what he wrote on my computer and we debug it live via a phone call, he has to imagine the program in his head. The crazy part is up until a few days ago he didn't have access to a computer. However! another inmate has an upcoming trial and because the contents of his trial contain to many papers, they provided this inmate with a simple laptop (no internet). My brother is not allowed to touch this laptop and he can only see this inmate 1 hour a day, so he convinced the inmate to sit next to him for my brother to tell him what to type, the other inmate types in the html+js on a notepad file and this way my brother can finally see his programs on a screen after months of only imagining how to program. Here is the program we wrote today: https://ift.tt/3gdfpIk My dream is for this to get some traction so when he calls I can tell him his program has users :) August 20, 2020 at 08:35AM

New Interactive “Shared Spaces” Map and Dashboard Launched

New Interactive “Shared Spaces” Map and Dashboard Launched
By Phillip Pierce

San Francisco’s popular Shared Spaces program, in which the SFMTA is a participating agency, now has an exciting new tool: an interactive map showing the locations and status of all the proposed Shared Spaces locations. The map is designed to make it easier for people to find Shared Spaces, check on permit status or simply track the progress of the program.   

 

Static image of the new “interactive” map showing Shared Spaces locations and stages in the approval process. Click through for a live view and explore in more detail. 

“We are so excited to see the new Shared Spaces Tracker that lets restaurants, businesses and residents see where the sidewalk and parking lane permit applications are located and details the status of each application,” said Laurie Thomas, Executive Director of the Golden Gate Restaurant Association. “The willingness to share this information publicly is a testament to how well the City has been working with businesses during this unprecedented time.”  

Shared Spaces allows merchants to use sidewalks, full or partial streets, and other nearby public spaces like parks, parking lots and plazas for restaurant pick-up and other neighborhood retail activities allowed under San Francisco’s Public Health Orders. The new program is a multiagency collaboration born out of the city’s Economic Recovery Task Force.   

There have been more than a thousand applications for Shared Spaces for uses like outdoor dining in parking spaces or allowing multiple retailers to operate in the open air by repurposing a parking lot. There are important guidelines for the program to ensure accessibility and safety. 

This Shared Space Dashboard is updated daily. Click through for a live view and explore in more detail. 

“The Shared Spaces program is vital to helping businesses like ours survive right now,” said China Live restaurant owners George Chan and Cindy Wong-Chen. “We are grateful for the responsiveness of the city to make this happen in such a short amount of time.”  

Businesses are also applying for temporary full street closures for certain days and hours of the week. The first two successes were Grant Avenue in Chinatown and Valencia Street in the Mission. More recent approvals include Irving Street between 19th and 20th Avenues and Gold Alley in North Beach. Starting later this month, SoMa will have a recurring Shared Space every Sunday on Folsom from 6th to 8th streets. More closures are in the works for the Bayview, Tenderloin, Castro, Excelsior, Marina, Sunset, Richmond and other parts of the city.  

Not every location is a good fit for every type of Shared Space, but the Shared Spaces teams work hard with businesses to find solutions. So far, fewer than 3% of applications were initially ineligible under program guidelines, but most of these were reworked into successful projects.

Next Steps: Keep Evolving and More Outreach 

The Shared Spaces program will continue to evolve with new health orders and as other types of business reopen. By looking at the data, we also know that there are more Shared Spaces in some neighborhoods than others. While some of that disparity is related to density and location of restaurants, we also know that not everyone has the resources to take advantage of these programs during this challenging time. In the weeks ahead, we are dedicating more resources to targeted outreach in areas that are not already benefiting from the program.  

For more information on the program or to apply, give feedback, report a problem or view the live tracker, visit sf.gov/SharedSpaces. Questions or media inquiries? Please email SharedSpaces@sfgov.org

Launch HN: Epihub (YC S20) – Shopify for teaching online https://ift.tt/3l3c6XN

Launch HN: Epihub (YC S20) – Shopify for teaching online Hey HN! I’m Uday, and I co-founded Epihub [0] with Kwasi and Michael ( https://epihub.com ). Epihub is Shopify for teaching online. Our software lets you schedule, meet, and bill clients from your own website. A few years ago, we started building a product called Epigrammar, which was a collaborative document annotation tool that let teachers rapidly give feedback to their students by identifying trends in their feedback. Kwasi and I really wanted to see if we could scale the tutoring experience to an entire classroom, since my co-founder Mike was teaching Classics at both a private school in Connecticut while running a non-profit tutoring program in Latin/Greek for public school students in New York. Mike would try out our products that we had built over the weekend during the week (sometimes to success), but oftentimes, things were not actually helping him teach. That’s when we'd go back to the drawing board. We spent a few years experimenting with different ideas in edtech trying to scale tutoring, as we obsessed over Bloom’s 2 sigma problem [1] including Superhuman for grading and even a test generator that could build assessments based on “backward-design [2]. We all lived together in Manhattan, built stuff, and would send it out to Mike to see what worked and what didn't. This spring, however, as COVID-19 shut down local businesses across the city (we still live in New York), we realized that there were much bigger problems facing tutoring, coaching, and training businesses like Mike's: bringing the actual business online. Whether you want to start up a coding bootcamp or run a tutoring business, you need a handful of products that are (ideally) white-labeled: a website builder, a way to process application forms, a CRM, a system to book appointments, a ticketing system for virtual classes, virtual classrooms, invoicing, and paystub tracking. When we spoke with tutors, coaches, and trainers, it was clear that there was a similar problem facing many different but similar businesses. How do you handle appointments? How do you handle virtual classes? How do you manage your team’s schedules? We spent our summer trying to build everything end-to-end, and finally, we’re excited to share that product with you today. Epihub lets you build a website (or embeds into your existing website) and also comes with a full system to schedule, meet, and bill clients in one place (you can change all the buttons, images, and language within your account to reflect your business so you can rename your employees to instructors or your currency to Solari). Similarly, you’re working online with individuals or groups, you can start teaching anyone on username.epihub.com and easily grow your entire team by adding additional seats for new instructors to manage their schedules and paystubs. So far, we’ve been working with tutors, coaches, trainers, but we have seen a bunch of interesting use-cases as well (including someone who wants to set up Epihub for virtual wine tasting and tours). The stack actually borrows a lot from our original product: it’s an Elixir/Phoenix application with a React frontend. We have a Zoom and Google Calendar integration, so you’ll also see appointments and requests in your calendar, as each hub comes with yoursubdomain.epihub.com/reserve to handle bookings from prospective clients. It's like a Calendly built to scale your team’s operations by syncing up invoicing, paystubs, and virtual classrooms. (Recently, we’ve been contemplating Liquid templating, and we’re considering building a Wordpress plugin. If anyone has worked with Liquid, Kwasi and I would love to chat.) If there’s anyone running a coaching, tutoring, or training business, or coding bootcamp, we'd love to hear how we could support your team. You can also book a personal onboarding with Mike over Zoom ( https://ift.tt/2E722wo ). Finally, I’ve been a member of HN for as long as I can remember. I’ve had my share of unfinished projects, and things I’ve been a bit nervous to launch here. I didn’t think I ever would launch anything, so this is pretty exciting. I’ll be online all day with my co-founders to chat about Epihub, tutoring, backward design, or Elixir in no specific order.
