Hi,

I have over 20 years in the industry starting out as a Linux SysAdmin / Network Engineer and now doing more Systems / Low level Programming, R&D, and occasional DevOps.

Looking for opportunities involving low level / embedded systems / backend software development. Happy to also do automation / SysAdmin / DevOps as well. Although not my forte, I like to do robust automated testing / QA for software to ensure they meet (potentially undocumented) requirements.

I live my life a quarter century at a time 2 years ago

Not complete without setting the autohide delay which doesn't have a GUI option, need to set with a 3rd party tool or `defaults`.

I live my life a quarter century at a time 2 years ago

I just hate the Dock. I wish there was a way to make it completely disappear. I have no need for it, everything I can do via Terminal/open, Spotlight, or cmd+tab app switcher. It's really annoying how baked into the OS it is.

Even trying to auto-hide the dock in new versions of MacOS is a huge pain in the arse.

Detecting SSH Tunnels (2017) 3 years ago

Although not the same as what you desire (which I fully agree with) - I implemented a encrypted TCP program tunneling app which tunnels over HTTP(S) websockets [1]. This should frustrate middleboxes, but would rather it be as native as HTTP(S) itself.
