Rust `String`s are always UTF-8 – distinct from `OsString`s which are not. Conversions are explicit, and the programmer is often forced to decide between conversions which are a) fallible or b) lossy. If neither choice is appropriate, the o

One alternative would be to define an ABI for using the x86-64 processor with 32-bit pointers. This would let everyone leave the processor in the more modern 64-bit mode without increasing pressure on the memory subsystem. Such a thing exis

TLS 1.3 still has SNI. SNI still transmits server names in the clear, just like always. This enables e.g. blocking a specific hostname without blocking an entire CDN, particularly now that CDNs are trying to stop domain fronting. Some peopl

`Expect: 100-continue` lets the server control this. If it responds "100 Continue", you upload the body. If it responds with a redirect, you redirect without uploading the body. This is standard HTTP/1.1, and it's used b

We've taken this a step further: `docker-compose.yml` uses a database image that has seed data baked right in. It's great.

Data storage devices have a finite lifetime, so data storage is necessarily a recurring expense. Copies that can't be read aren't copies any more, which means regular access is a requirement, which means another recurring expense.
