Throughout the week, I read a lot of blog-posts, articles, and so forth, that has to do with things that interest me:

  • data science
  • data in general
  • distributed computing
  • SQL Server
  • transactions (both db as well as non db)
  • and other “stuff”

This blog-post is the “roundup” of the things that have been most interesting to me, for the week just ending.



  • My Emacs journey. This blog post by Murat, where he talks about Emacs, brings me back to the early days of .NET, (pre 1.0), where I created an Emacs .NET intellisense extension. Ah, those were the days!

Distributed Computing

  • Overload control for scaling WeChat microservices. In this blog post Adrian looks at a white paper discussing how WeChat handles overload control. Some very impressive numbers and quotes: “WeChat’s microservice system accommodates more than 3000 services running on over 20,000 machines in the WeChat business system, and these numbers keep increasing as WeChat is becoming immensely popular… As WeChat is ever actively evolving, its microservice system has been undergoing fast iteration of service updates. For instance, from March to May in 2018, WeChat’s microservice system experienced almost a thousand changes per day on average.”. Think about that; 20,000 machines, thousand code changes per day, wow!


SQL Server 2019

  • Creating a data hub for your analytics with PolyBase. SQL Server 2019 CTP 2.0 introduces new connectors for PolyBase, and this blog post discusses how the new connectors enable customers to leverage PolyBase for creating a virtual data hub for a wide variety of data sources within the enterprise. Very interesting!

Data Science / AI
