Removing Uncertainty: The Tip Of The Iceberg - James Stanier #Leadership #Management
tl;dr: “When you’re staring a huge, challenging project in the face, don’t align your team around just getting it done. Instead, align your team around continually reducing uncertainty…” James advises us to prioritize the most uncertain parts of the project and focus efforts on getting answers. Answers fall into two broad categories: that it is possible, as proved by code, or that it’s not possible, but yields another avenue to try. You repeat this process until you’re done, or until you think it’s best to stop. “Focussing on reducing uncertainty builds momentum and trust both inside and outside of the team.” |

How DoorDash Designed A Successful Write-Heavy Scalable And Reliable Inventory Platform - Chuanpin Zhu, Debalin Das #DataStructure
tl;dr: “As DoorDash made the move from made-to-order restaurant delivery into the Convenience and Grocery (CnG) business, we had to find a way to manage an online inventory per merchant per store that went from tens of items to tens of thousands of items. Having multiple CnG merchants on the platform means constantly refreshing their offerings, a huge inventory management problem that would need to be operated at scale. To solve this scaling problem our team built a write-heavy inventory platform that would be able to keep up with all the changes on the platform… This article outlines the challenges faced while building the inventory platform and how we solved them after multiple iterations of experimentation and analysis.” |

We Stand To Save $7m Over Five Years From Our Cloud Exit - David Heinemeier Hansson #Cloud
tl;dr: “The rough math goes like this: We spent $3.2m on cloud in 2022. Just under a million of that was on storing 8 petabytes of files in S3, fully replicated across several regions. So that leaves ~$2.3m on everything else: app servers, cache servers, database servers, search servers, the works. That's the part of the budget we intend to bring to zero in 2023. Then we'll worry about exiting the 8PB from S3 in 2024.” |

My Favourite 3 Lines Of CSS
- Andy Bell #CSS
tl;dr: “The main reason I’ve written this post though, is to send people to it when they ask why I use .flow or use margin, but also, I hope you’ve seen how damn powerful CSS Custom Properties are. They’re certainly more than just CSS variables, that’s for sure.” |
