Development tools for embedded projects shouldn't need fucking internet to operate. Every fucking app needing internet to even startup is getting more and more stupid. I do a LOT of development offline. I usually have my dev machine away from internet for weeks at a time. It very nice to not have to deal with update issues and the like during this time. So naturally I choose tools to do offline programming for both desktop and embedded. So I decided that for my embedded work I wanted to have better environment than Arduino IDE. Now enters VSCode with Platform IO. I download all the target platforms for my boards. I get it all working and installed. Then I take my computer to my non internet location. I fire up VSCode, select the platform, create a test project, and compile the code. Everything is working great. Then I go to upload the code to my board:
"Blah blah blah you need internet first time talking to a board blah blah blah." Seriously? WTF? Who does stupid shit like this? Once you install your dev tools they should be fucking installed! Now I have to drag my fucking dev boards to another location and do a test install just to do fucking offline programming.

FUCK YOU PLATFORM IO!

Notice I don't blame VSCode for this. I know this IDE is very internet dependent, but it works once you get your plugins installed regardless of internet. Unless of course you are doing internet based programming.
