Yes! Exactly this. My last EV used 22 MWh over 6.5 years. That works out to 390W. My solar array is located at high latitudes (northern Minnesota), the mounting angle isn't great, it's occasionally covered in snow, etc. In these c

You're right, and in fact S3 does this with the `ETag:` header… in the simple case. S3 also supports more complicated cases where the entire object may not be visible to any single component while it is being written, and in those case

It is common to use multipart uploads for large objects, since this both increases throughput and decreases latency. Individual part uploads can happen in parallel and complete in any sequence. There's no architectural requirement that

The best treatment is at: https://blog.rust-lang.org/2024/03/30/i128-layout-update.htm... Note also that this involves LLVM, so clang < 18 had the same u128 behavior as Rust < 1.77/1.78.

Large single family homes have 400A 1Ø 120/240V service, which is 96 kW peak or 76.8 kW for NEC's definition of continuous. Most have 200A service or smaller, which is half that. What load do you imagine causes "most" ho

In 2024 I would suggest deploying 2x25G instead, via e.g. MCX4121. Pricing is similar (<$30 NICs), but: * 2x25G throughput is higher than 40G, * 25G latency is lower than 40G, * you can use 25G ports as 10G ports, and * you can use DACs
