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 on. 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

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

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 neighb

Show HN: HTML Planet for Kids – A HTML and CSS Course for Children https://ift.tt/3ALUlDj

Show HN: HTML Planet for Kids – A HTML and CSS Course for Children Hi HN, We are Matjaz (that’s me) and Benjamin - a father & son team - from HTML Planet for Kids (https://ift.tt/3mKf9G9), an online space where children learn and create with HTML & CSS. I’m the author of Pinegrow Web Editor (launched on HN seven years ago) and Ben is a 11 year old boy full of creativity and ingenuity. In early 2020 our family embarking on a journey around the world. Thanks to the Covid pandemic we immediately got stuck at our first destination. With time saved on not traveling around, Ben and I finished our Maths lessons early and had some extra time to do a project together. We did research on existing HTML & CSS courses and discovered that all teach HTML & CSS exclusively through coding, and after the course is done, they offer no follow-up to engage kids in using their newly acquired skills. We decided to take a month off and create a HTML & CSS course for children, based on the
