Platform Adjacency Theory

Alex Russell

Other use-cases weren't addressable with early 2000's tech. TL;DR: Does it matter if the web platform adds new capabilities? And if it should, which ones? The web is a meta-platform. Like other meta-platforms the web thrives or declines to the extent it can accomplish the lion's share of the things we expect most computers to do. Adjacency to the current set of capabilities provides a disciplined way to think about where to invest next when working to stave off irrelevance.

tempdb Enhancements in SQL Server 2019

SQL Performance

I have been making the same recommendations about tempdb since I started working with SQL Server over 15 years ago, when I was working with customers running version 2000. The gist of it: create multiple data files that are sized the same, with the same auto-growth settings, enable trace flag 1118 (and maybe 1117), and reduce your tempdb use. From the customer side, this has been the limit of what can be done*, until SQL Server 2019.
