Corrections:
- At 9:44, the default unbuffered channel in Go does not hold any items and has a buffer size of 0. Sends to such a channel are blocked until another goroutine is ready to receive the value. The illustration in the video shows a *buffered channel of size 1* however the overall point still stands.

Hi Kevin, amazing content as always! One minor correction @9:54 tho: Go unbuffered channel's length is 0, instead of 1, and it means the sender will get blocked until a receiver receives the value. What the video @9:54 showcase is actually a buffered channel with length 1 (e.g. result of make(chan string, 1)).

Or HashiCorp, being a multi-billion dollar company, could just maintain the fucking project themselves instead of blindly using a 4-year-old abandoned pet project from some random person's GitHub page and trusting it to work in a large production environment.

I still remember the day that it went down, people were blaming Chipotle (american fast casual chain) because they had an event that same day where you could claim a free burrito. People suspected that it was due to a mass influx of people, I knew (and a bunch of people too) that this wasn't an issue with influx of people. At the end of the day, it was a fun journey (more or less with the conspiracies, guessing correctly that it went down for 3 days months before this outage, and youtubers just milking on the outage). Thank you for making a video about this.

@@baribari1000 Yeah, it was super easy too, you could do it in like 2 minutes on a new account, it gave you a free entrée instead of a free burrito, so you could actually choose most meals you wanted.

Imagine how it must feel, starting a free project just as a hobby, and planning to abandon it eventually, then pretty much half the internet starts using it as an important building block to support the web. Now you're just sitting there, and have a choice to make. Stop maintaining the software, and pretty much break half the internet or keep going, getting zero thanks, and zero dollars for your work.
