Learning through failure - a keyboard creation journey

Image
tl;dr Built a custom keyboard cuz I have weirdo nerve pain issues.   Learned a lot cuz I failed a lot.   Maybe 'do it right the first time' is a bad frame of mind.   The keyboard ended up being kinda nifty.   It has lights, and a trackball, and QMK, and it helps my issues.   \o/ ( tl;dr is internet lingo that means, too long; didn't read ) Pain as a key ingredient An old proverb says, 'necessity is the mother of invention', and that is how this story begins. Over the last few years, age or stress or something has caught up with me and I developed the need to change my human-to-computer interface.  Mousing changed to trackballing.  The traditional keyboard was swapped out for an ergonomic, and then split keyboard.  Complicated multi-finger-and-hand key combinations were replaced by single keypress macros.  And yet more was still needed.

Learning Opportunities - Watching/listening list

Over the last year I've spent a lot of time learning (thank you, long commute & lunch hours).  Many topics ranging from Chef to DevOps to architecture concepts to management concepts and everything in between.  Why have I done this?

DFSR - eventid 4312 - replication just won't work

This warning isn't documented that well on the googles, so here's some google fodder: You are trying to set up replication for a DFS folder (no existing replication) Source server is 2008R2, 'branch office' server is 2012R2 (I'm moving all our infra to 2012R2) You have no issues getting replication configured You see the DFSR folders get created on the other end, but nothing stages Finally you get EventID 4312: The DFS Replication service failed to get folder information when walking the file system on a journal wrap or loss recovery due to repeated sharing violations encountered on a folder. The service cannot replicate the folder and files in that folder until the sharing violation is resolved.    Additional Information:  Folder: F:\Users$\user.name\Desktop\Random Folder Name\  Replicated Folder Root: F:\Users$  File ID: {00000000-0000-0000-0000-000000000000}-v0  Replicated Folder Name: Users  Replicated Folder ID: 33F0449D...
