@___Dario_____ Perfect for 3D printing my own Microsoft Surface RTX Spark Dev Box. Say what you want about Microsoft, but the design of the 3D printed aluminum body has many pluses.

I will be visiting Osaka soon. Do you have any recommendations for spots where I can capture some cool trains with my line scan camera? I would also like to capture the Osaka Metro 400 series as it looks very unique. If you know of any locations near Osaka Station that have good outdoor lighting and have trains fully visible on the side and preferably traveling near a constant speed, I would appreciate that very much.

Actually, melanin does affect reflectivity in infrared wavelengths like 850 nm and 905 nm where lidar tends to operate, though not as much as in visible light. Lower reflectivity means lidar needs to get closer to detect them. Furthermore, since lidar outputs infrared intensity, and in some cases even visible RGB color, it can in fact physically "see race".

@AIDRIVR the 3D reconstructions don't need human labelers

@Keller haha i took the lead photo of that wikipedia article

@gabriberton classical bundle adjustment is still the goat

@fpv_labs You can also do a combination of continuous time and discrete time approaches. It's often sufficient to use a first order approximation to "de-warp" the distorted features using velocity estimates from VIO or even just IMU. Later loop closures won't affect it too much.

@ousterlidar gotta tell Serve Robotics to turn their dual returns on

@BenBajarin he actually said several thousand, not seven thousand. You misheard.

@jimbelosic @emm0sh I really want to try out Sendcutsend's CNC services but $500 for this 3 axis machinable part is really high compared to a fifth of the price at JLC.

@bryancsk @zephyr_z9 with their Americans competitors going bankrupt and Chinese competitors getting banned from the country, Angus just can't stop winning

@Waymo mildly disappointed that the San Jose airport is right at the edge of the service area and most of San Jose itself is not included

@teslaenergy why is my powerwall importing from grid even though it's at 50%? import costs 5x more than export and now the powerwall fills up during the day on solar and i have to export for pennies. i lost hundreds of dollars using 100% for time based control.

@quxiaoyin haha i wish i had a trust fund...

@robotaxi yeah it's definitely a bug. if i make a new account, i can access it no problem. probably some flags are incorrectly set in my main account. please fix it @robotaxi

[Daniel Lu @dllu]

@robotaxi why does the robotaxi app always say network unavailable when in fact my internet is working fine? i can also click the hamburger menu on the top right to view my profile and stuff. seems like a bug
