Summary: Instead of downloading both the forward delta and the backward delta as part of the update, the system computes the backward delta and stores it on disk.
- reed1234 5y agoSeems like a very simple change.
- deelly 5y agoOh my....
- capableweb 5y agoMost changes seem simple when you think about just the change itself, but then at the scale of Microsoft (I haven't dealt with that personally), things get very complicated, very quickly. Consider all the different setups people have, what can go wrong and so on, and suddenly something that seems simple could actually have a huge impact on a large amount of people/setups.
- xoac 5y agoAre you a product manager?
- acqq 5y agoYes, that's really all to it. Compute the delta from the current revision to the base and keep that delta on the user's computer. It seems that because they haven't done that until now (keeping the delta to the base locally) they distributed these same otherwise locally computable deltas to every Windows computer in the world with every update! If I understood it correctly they patented that "approach" and wrote this much (or more) to make it appear more clever and worth of a patent? "1] The approach described above was filed on 03/12/2021 as U.S. Provisional Patent Application No. 63/160,284 “REVERSE UPDATE DATA GENERATION”"
