Commemorating Rosa Parks Day By Jeanne Brophy “I do the very best I can to look upon life with optimism and hope and looking forward to a better day, but I don’t think there is any such thing as complete happiness.” ~ Rosa Parks on optimism Today marks the 20th anniversary of Rosa Parks Day as legislated by the California State Legislature.  Known as the mother of the civil rights movement Rosa Parks ignited a civil rights movement with her refusal to move from her seat. It all began   sixty-five years ago, on December 5, 1955 in Montgomery, Alabama , Rosa Parks was jailed and fined $10 for refusing to give up her seat on a public bus to a white man, a violation of the city’s racial segregation laws.

Launch HN: Scrimba (YC S20) – Interactive video for learning to code Hi all, I’m Per, co-founder of Scrimba. We are building an interactive video format for teaching and learning how to code. The main benefit is that students can pause the video and edit the code whenever they want. We think this is needed is because over 70% of people who are trying to learn to code today use videos. But since videos aren’t interactive, students end up mirroring the instructors’ code line-by-line in their local code editors. This is time consuming, and it often causes problems with local dev environment setup. Scrimba solves these problems as it enables students to pause the screencast and modify the instructors’ code directly inside the player. So when a Scrimba student feels confused, she jumps into the screencast and plays around with the code (editing, running, debugging) until she’s made sense of it. As a consequence, she learns faster. Technically, this is possible because we have merged the IDE...

Year-End Highlights from the SFMTA Photo Archive By Jeremy Menzies As we approach the close of 2019, here's a short "year in review" of our favorite history blog posts of the year. So climb aboard and have your ticket to the past ready, 'cause this trip back in time is about to depart! First on this year's list is our celebration of the 80th anniversary of the 1939 Golden Gate International Exhibition   on Treasure Island. We unveiled dozens of beautiful large-format photos of the GGIE in our February post. A view of Treasure Island and the Golden Gate International Exposition from Yerba Buena Island circa 1939. The "Tower of the Sun" and other fairground buildings were transformed at night into canvases for intensely colorful light displays. Following the GGIE up in March was our post on historic Muni women in celebration of Women's History Month. Muni's first female inspector, Evelyn Wells, monitors a bus line in this 1979 shot. Ap...
