alt Hacker NewsAlso how many times do we have to learn that letting badly programmed software die when unexpected things happen is the better option because it means people actually notice that there's a problem. Silent compatibility hacks are the worst, they guarantee problems never get fixed and the stack of hacks never gets smaller.
Microsoft has historically been one of the leaders on the wrong side of this one, but they have also demonstrated how effective it is to call out badly behaved software and make it annoy the users with UAC. When Vista came out, so many applications needed elevated privileges to run because they were badly designed to write user data in system locations, but now their application was more annoying to use and came with a scary dialog about it making changes to your computer that other better-designed software didn't get.
More often than not if a program didn't actually intend to change system settings it was just a matter of badly chosen default paths which are pretty trivial to fix, but so many vendors just would not do it despite years of complaints from NT admins wanting to not have to spend hours with Process Explorer figuring out specific permissions to grant limited users enough access. Once their failures were put front and center, calling their application out as the one getting things wrong every time the user ran it, they suddenly had motivation to fix it.

Agreed. I feel like this attitude has been holding Python back, too. It's one thing to criticize "move fast and break things", but it's also not good to ignore already existing breakage just because the pieces still fit together neatly, and it's not good to refuse to move at all.
Now everything installs to a user local folder, runs as the user, there are no UAC prompts, and malware can just freely tamper with other applications, act as the user, and harvest all data the user has access to.
Hey, but at least it can’t touch the System32 folder.
Great job guys.

Objective-C ahem nil messaging...

Sadly, we will never learn this because failing fast runs counter to intuition, and a class of person will never override it.

For security it's better, but in many cases if you're not writing security-oriented software it can be worse from a user perspective. I remember the first job I had over 20 years ago was working on VoD streaming and one of the "tricks" to improve stability was mmap'ing the 0 page so that NULL dereferences wouldn't immediately segfault. Ugly as hell but when you were working with all sorts of more or less well coded media codecs and security wasn't a concern at all (worst case scenario the user would stream movies without paying) it made some amount of sense.
I suspect that Microsoft has the same history: the entire Windows platform was built with single-user PCs in mind, mostly only dealing with trusted input. The users were also expected to be tech-illiterate for the most part and unable to troubleshoot deep technical issues.
More recently I'm still working on video transmission, but on the production side this time. I also originally adopted the mentality that I should crash early if some unexpected situation was encountered, but I ended up walking that back a lot, because having a critical piece of live media production reboot mid FIFA worldcup final is generally Not Great. Degraded functionality is usually preferable. I still crash early in dev builds, but the production code just logs an error and continues if at all possible.
That said, I definitely agree with you for something like password handling. In this case, I do think it's warranted to crash the program without survivors if something is amiss.
