I wouldn't be surprised to see really good static analysis and automated code review tools coming out of these teams very soon.
wsl on windows 10 has been amazing to develop and work on.
Now imagine how amazing it would be just on Ubuntu ;-)
e.g. this is in my .bashrc in wsl, it writes stdout to my windows clipboard:
function cb () { powershell.exe -command "\$input | set-clipboard" }
Windows gets tons of hate in our community, but I gave it a chance a couple years ago after being frustrated with osx and it has been amazing and I think a lot of people would come around to it if they gave it a chance. I am biased towards linux though since I'm an sre, so maybe that is why I never could quite get comfortable on osx. I really disliked having to learn how to do something once on a mac, then do that same thing again on linux to get something into production.
I don't even remember the last time Windows got in my way, in fact.
But no matter how much work you put into your Windows install it will be just as slow/fast, uncustomizable, and unoptimizable as it was out of the box.
The real strength of Windows is backwards compatibility, especially dealing with proprietary software. Its messiness is a relic of the way things were done in the past, it is also the reason why my 20+ year old binary still runs. And it does without containers or full VMs.
I much prefer developing on Linux (I still miss the Visual Studio debugger), but different platform, different philosophy.
Note: I don't know much about mainframes. I heard they really are the champions of backwards compatibility. But I don't think the same principles are applicable to consumer machines.
