How we trimmed the Sentry JavaScript SDK file size by 20%
SDKs naturally increase in size over time. After all, it does take more bytes to implement more features. This is not a big deal for most languages—the relative size of each new feature is small, and load times and storage aren’t big concerns for code running on a server. Larger JS bundles mean longer load times, which in turn increase user misery, which then can cause the user to leave pages entirely.

Alias: An approach to .NET Assembly Conflict Resolution
Most plugin based models load all assemblies into a single shared context. This is a common approach because it has better memory usage and startup performance. The history and rules of assembly loading in .NET is convoluted; its current status makes it difficult (and sometimes impossible) to load multiple different versions of the same assembly into a shared context. Instead of trying to struggle with existing options we decided to build a new tool: Alias.
