Show HN: Can Strava Do This? I recently added a new feature to the MTB Hangtime app that allows users to generate a telemetry overlay on top of an action camera video. The demo video was created using only the app, no third party video editing tools. The goal was to be able to capture the telemetry data with a smart phone and the video with a GoPro, then generate the output video without any additional tools. https://www.youtube.com/watch?v=Jqul6Y-U2Pw November 3, 2022 at 12:38AM

Show HN: HiSHtory: Your shell history in context, synced, and queryable hiSHtory is a better shell history. It stores your shell history in context (what directory you ran the command it, whether it succeeded or failed, how long it took, etc). This is all stored locally and end-to-end encrypted for syncing to to all your other computers. All of this is easily queryable via Control-R and via the hishtory CLI. This means from your laptop, you can easily find that complex bash pipeline you wrote on your server, and see the context in which you ran it. https://ift.tt/1uBYhJi November 2, 2022 at 04:13AM

Central Subway Opens November 19 with Special Weekend Service

Central Subway Opens November 19 with Special Weekend Service
By Mariana Maguire

Central Subway special weekend service starts November 19 with service to Chinatown-Rose Pak Station, Union Square/Market Street Station, Yerba Buena/Moscone Station and 4th and Brannan.

On Saturday, November 19, the Central Subway makes its historic debut with special weekend service, Saturdays and Sundays, from 8 a.m. to 12 a.m. with trains every 12 minutes. During this special weekend service, customers will have a chance to ride through the new Central Subway for free and get to know the four new stations: Chinatown-Rose Pak at Stockton and Clay streets, Union Square/Market Street Station at Geary and Stockton streets, Yerba Buena/Moscone Station at 4th and Folsom and the new 4th & Brannan stop at 4th and Brannan streets.

During the special weekend service, customers can transfer to the new Central Subway service at Powell Station from Muni Metro and BART by walking underground to the new Union Square/Market Street Station.

The new Central Subway connects communities to destinations including Chinatown, Union Square, Yerba Buena Gardens, the Moscone Convention Centre, the Metreon and SFMOMA, just in time for the holidays.

Wayfinding Guidance

SFMTA ambassadors will provide wayfinding guidance online and in-person during special weekend service to help customers learn to navigate the new Central Subway stations and Muni Metro connections.

Online guidance will include a video that will be available on our website. Visit our Service Changes webpage (SFMTA.com/ServiceChanges) to learn more and sign up for a tour.

New T Third service in Central Subway is planned to start January 7

Beginning Saturday, January 7, SFMTA is planning to run the new T Third line service via Central Subway seven days a week, providing a direct connection from Chinatown-Rose Pak Station to Sunnydale. Weekday service will run from 6 a.m. to 12 a.m.. and weekend service will run from 8 a.m. to 12 a.m.. Stay tuned for more details!

Show HN: Minimax – A Compressed-First, Microcoded RISC-V CPU https://ift.tt/7Uyil8c

Show HN: Minimax – A Compressed-First, Microcoded RISC-V CPU RISC-V's compressed instruction (RVC) extension is intended as an add-on to the regular, 32-bit instruction set, not a replacement or competitor. Its designers intended RVC instructions to be expanded into regular 32-bit RV32I equivalents via a pre-decoder. What happens if we explicitly architect a RISC-V CPU to execute RVC instructions, and "mop up" any RV32I instructions that aren't convenient via a microcode layer? What architectural optimizations are unlocked as a result? "Minimax" is an experimental RISC-V implementation intended to establish if an RVC-optimized CPU is, in practice, any simpler than an ordinary RV32I core with pre-decoder. While it passes a modest test suite, you should not use it without caution. (There are a large number of excellent, open source, "little" RISC-V implementations you should probably use reach for first.) https://ift.tt/pNa3POS November 1, 2022 at 09:11PM
