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

This post is as much for you as it is for me to come back to when I wonder what to do when SQL Serer Machine Learning Services all of a sudden stops working after a SQL Server upgrade.
Background
Last week I did a complete reformat of my development box at home and installed the latest version of Windows 10: the 1803 build, also called the April 2018 update.
NOTE: I usually try to reformat my box at least twice a year, to ensure it is not too "bogged" down by old "cruft", and that it has the latest and greatest.
After the reformat I installed all my necessary applications, among them SQL Server 2017 with the in-database analytics components (R and Python). After installation I tested that it all worked and made sure I could execute my usual test scripts for sp_execute_external_script:
EXEC sp_execute_external_script @language = N'R'
, @script = N'd <- 42'
Code Snippet 1: Test Script for R
The "moral" equivalent to Code Snippet 1 in Python also worked without an issue:
EXEC sp_execute_external_script @language = N'Python'
, @script = N'd = 42'
Code Snippet 2: Test Script for Python
Cool, all is "A-OK"! A couple of days go by, and I see that there is a Cumulative Update (CU) for SQL Server 2017 - CU7. I install it and does not think much about it. I mean: "what can go wrong, how hard can it be?". A couple of days later and I am busy writing the follow-up post to sp_execute_external_script and SQL Compute Context - I when I try to execute sp_execute_external_script, and it falls over!
