Show HN: mybf.io - platform for software reviews with social network aspect https://ift.tt/3j4fpyz

Show HN: mybf.io - platform for software reviews with social network aspect Hi! Recently I've launched - mybfio.io - platform for software reviews with social network aspect. Prehistory Many great system are already in place that allow people to search and rate software products, including the site I am publishing this post. However I have always felt that those systems are not specifically centered around product/software development lifecycle (releases, real users feedback over a product entire lifetime, so on) and often too broad or not designed specifically for that type of work, which is ok. Why? As an opensource author I would like to have constant real users feedback, not necessarily tied only to bugs and feature requests. And even if my project is not that big and not that promoted I still want my voice will be heard among myriads of other projects and to gain my own community. Who? Opensource authors seeking to build community around products they maintain Users seeking for relevant and well maintained software to fit best theirs needs What? Welcome mybfi.io, see the "Principles" article on mybfi.io site - https://ift.tt/3mNHdZe explaining some of those principles in more details. PS The mybfio service is still in active development, things might change, but any feedback is valuable. October 14, 2021 at 10:58PM

Show HN: OtterTune – Automated Database Tuning Service for RDS MySQL/Postgres https://ift.tt/3DF7Hmv

Show HN: OtterTune – Automated Database Tuning Service for RDS MySQL/Postgres Yo. OtterTune is a database optimization service. It uses machine learning to automatically tune your MySQL and Postgres configuration (i.e., RDS parameter groups) to improve performance and reduce costs. It does this by only looking at your database's runtime metrics (e.g., INNODB_METRICS, pg_stat_database, CloudWatch). We don't need to examine sensitive queries or user tables. We spun this project out of my research group at Carnegie Mellon University in 2020. This week we've announced that OtterTune is now available to the public. We are offering everyone a starter account to try it out on their Postgres RDS or MySQL RDS databases (all versions, AWS US AZs only). We have seen OtterTune achieve 2-4x performance improvements and 50% cost reductions for these databases compared to using Amazon's default RDS configuration. I am happy to answer any questions that you may have about how OtterTune works here. -- Andy ================ More Info: * 5min Demo Video: https://ift.tt/3uoRmNP * Free Account Sign-up: https://ift.tt/3BHygqI October 14, 2021 at 08:54PM

Sunday Streets Returns October 17, with Phoenix Day

Sunday Streets Returns October 17, with Phoenix Day
By Pamela Johnson

For 13 years, the SFMTA and Livable City have brought "Sunday Streets" to San Francisco neighborhoods. Sunday Streets encourages communities to transform miles of car-congested streets into car-free spaces for neighbors to gather, kids to play, and for organizations and businesses to connect. On October 17, 2021, after more than 18 months of Covid-related shutdowns, Sunday Streets Phoenix Day will again bring free recreational activities, resources, and fun to the streets for tens of thousands of San Franciscans to enjoy. While Sunday Streets was celebrated in one neighborhood at a time in the past, this year's Phoenix Day spans various districts in the City for a simultaneous celebration of community, health, and resilience. This year's theme is "One City. One day. Rising together.”

 Highlights this year include historic Sunday Streets SF routes, a 20+ mile community bike ride, three neighbor-run block parties, pop-ups, and free community-hosted activities across the city. Along the way, participants will be offered free health and wellness activities as well as cultural offerings and open space for the whole family to enjoy.  As part of the block party program for Phoenix Day, the City has issued more than 30 permits for neighbors from different communities to participate in the day's festivities.

 Phoenix Day is about communities coming together to celebrate healthy fun as San Francisco reopens during the COVID-19 pandemic. Supporting the City’s economic recovery and its residents physical and mental health includes bringing joy back to our communities as we gather again outside to have fun with family and friends. At the same time, we are committed to keeping our community safe from COVID-19 and encourage people to wear masks in crowded outdoor spaces and always indoors, use hand sanitizer, and stay home if they are sick.

 In this critical moment for San Francisco it's more important than ever to transform our streets into places that foster human connection and civic pride. Sunday Streets Phoenix Day will be a monumental opportunity to do that together. 

About Sunday Streets

In 2008 the Sunday Streets SF program was started as a one-day pilot by then Mayor Gavin Newsom and the SF ShapeUp Coalition. It was inspired by the La Ciclovía initiative in the Colombian capital of Bogotá.  Since starting the program in 2008, the nonprofit Livable City in partnership with SFMTA and City and County of San Francisco has grown Sunday Streets into one of North America’s premiere open street programs serving 100,000 residents in diverse neighborhoods across San Francisco.
