In the beginning of the video, the narration talks about the spillway plug being a feature designed to erode in a fashion that delayed/slowed the inevitable failure of the entire dam. In this case, the spillway plug helped the dam release water in a semi-controlled fashion over a series of hours, instead of an uncontrolled fashion in a matter of minutes.

This post [1] from that thread is the simplest presentation of the current and expected scenarios than anything I've seen elsewhere, including the OP. If they are able to run the main spillway at the current rate of 100,000 cfs without concern for further major erosion, the outflow outpaces anything but the highest inflows from the recent storms.

In 1986, water flowed over the top of the Auburn Cofferdam and resulted in complete failure of the dam. See this video of that incident [1] for an example of how the overtopping of an earthen dam leads to failure.

The capacity of the intact spillway is ~250,000 cfs - the capacity of the Feather River through Oroville and Yuba City below, currently in the lower flood stages with 100,000 cfs outflows from the main spillway, is much lower than that. In addition to attempting to minimize further erosion of the main spillway, they set an outflow level that wouldn't flood the towns downstream.

I'm having a difficult time imagining a scenario where an energy company in Houston or a tech company in Austin needs to search overseas for candidates with skills who aren't worth multiples of 130K/yr in value.

20% growth would mean the wealth in the area would double every 3.46 years.
This morning, it was announced that the US GDP grew at an annual rate of 2.9% last quarter, accompanied by the WSJ headline "US Economy Roars Back" [1].
20% growth is nowhere near "reasonable".

Awesome. Thank you for putting this together. It looks like the consensus is the PostgreSQL documentation.

In that spirit, what are the best resources for getting started and diving in to working with PostgreSQL?

I had the same issue not being able to ssh into the shipped OS. While updating to the latest OS, I ran into similar issues writing the latest version to the eMMC memory and also thought I bricked my board. The external SD port and the eMMC Flasher images really are a "get out of jail free card."
This board is a beautiful little piece of hardware. I'm really looking forward to tinkering around with it.
Re:Tool for exploring color schemes

I think this is awesome, and have been using it quite a bit during the past few days.
After trying to use it to find a red based color scheme, I found that many of the reds that I wanted to save often fell underneath the scroll bar on the left hand side, which meant that I wasn't able to save their values.
Re:Developing a Raspberry PI app with Visual Studio

While I'm of the opinion that tinkering away with a Raspberry Pi is inherently a great thing, developing for a minimalistic piece of nearly open source hardware running an open source OS using software as bloated and proprietary as Visual Studio really rubs me the wrong way.
