If you upgrade then, for example, you can't run all of your PHP 5 code in PHP 8, most of it you can but you will have to change the parts that are broken, which are the areas that are repaired in PHP 8.
Same goes for other languages like C# or Python
Erlang is designed with a mechanism that makes it easy for external processes to monitor for crashes (or hardware failures), rather than an in-process mechanism like exception handling used in many other programming languages.
Erlang was designed with the aim of improving the development of telephony applications.
The Erlang runtime system provides strict process isolation between Erlang processes (this includes data and garbage collection, separated individually by each Erlang process) and transparent communication between processes on different Erlang nodes (on different hosts).
The "let it crash" philosophy prefers that a process be completely restarted rather than trying to recover from a serious failure. Though it still requires handling of errors, this philosophy results in less code devoted to defensive programming where error-handling code is highly contextual and specific.
Pilot switched mode back to normal flight because it was the switch to landing mode is what caused his HUD and PFD to turn off in the first place.
There is a recent video now from a former Microsoft employee where he explains that those drivers that get WHQL certification are ran on test machines in stress conditions for some time, or at least that is how it used to be when he worked there.
Since that process is probably quite slow to be able to push update within a couple hours Crowdstrike just bypassed the QA testing by injecting their own data files into the driver.
