py.test has this curious feature 'xfail', that allows you to ensure a test execute, but expect it to fail. Not sure I've had a need for it.

It is remarkably hard to escape command line arguments safely on Windows, and the standard libraries of multiple languages have needed patching:

BatBadBut: You can't securely execute commands on Windows

Introduction Hello, I’m RyotaK ( @ryotkak ), a security engineer at Flatt Security Inc. Recently, I reported multiple vulnerabilities to several programming languages that allowed an attacker to perform command injection on Windows when the specific conditions were satisfied. Today, affected vendors published advisories of these vulnerabilities , so I’m documenting the details here to provide more information about the vulnerabilities and minimize the confusion regarding the high CVSS score. TL;DR The BatBadBut is a vulnerability that allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.

Old news, but I really like how node v12.17 will speculatively execute pure functions in the REPL.

Node.js — Node.js v12.17.0 (LTS)

Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.

Gate is exploring transferring program state (like Smalltalk images), but leveraging wasm to execute untrusted code. An exciting model! https://savo.la/introduction-to-gate.html Execution of untrusted code still feels like a really underexplored space.
