I believe the MTBF argument still applies to Starlink. Regarding the minimal risk condition / fallback behavior, a central point of the article was that slowing or stopping are almost always unacceptable on freeways because of the spee

Cell networks are even longer lead time and more capital intensive than autonomous driving ;) even if we only consider the fcc + local permitting time, it already makes this option difficult.

Author here. At the mean time between failures needed to exceed human performance, the uptime of the network connection quickly becomes a limiting factor. It’s possible to pick only routes that have great cell coverage but this limits comme

Most high end sensors, especially lidars, are targeted at L4 applications. Otherwise the price cannot be justified. It’s a safe bet that sensor makers are including AV developers in their market research. For lidar, the range is also limite

The cab, sensors, and compute are also expensive, not to mention other variable costs like staff for remote assistance, maintenance, and first/last mile

I agree achieving human safety equivalent is the minimum bar. Ex: We can all agree that if your system is below human safety, it is definitely unacceptable. That’s not the argument being presented though. For example Waymo claims to exceed

Author here. the shorter reaction times you mentioned are collected under ideal conditions, like the person knows they are being tested and only needs to push a button or whatever. In driving, the reaction time is end to end, including perc

I guess this post is a little bit different, because VMs are designed to be portable across different hosts. Even hypervisor software without live migration still lets you freeze the VM’s state to a file which can be copied to a new host. H

I don’t think this is accurate. Within a single region, S3 stores in multiple availability zones by default. https://aws.amazon.com/s3/faqs/

I’m a Backblaze customer of many years & respect their team a lot. But seriously, “out-Googling Google” because they have cheaper storage is a meme that needs to die. GCP and AWS both store full copies of your data in multiple locations

I’m sure Amazon, Google, Facebook, etc collect their own stats on drive failure. It would be almost negligent if they were just guessing in the dark every time they buy drives. Main difference is probably Backblaze is small enough to publis

This is an unusually large open source project, especially for NSA. I wonder whether they were motivated to release this tool because of their recent brain drain / hiring problems.

Tesla Autopilot should be recalled via the next OTA update. The “Autopilot” branding implies that users need not pay attention, when in reality, the system needs interventions at infrequent but hard-to-predict times. If an engineer at Apple
