Prepare to spend a little cash on a wild ride. You are about to go from an expensive, Jet-A-enriched glass-and-steel shopping mall to an acoustic-tile-ceilinged underground train pit with a bowling alley on top.

Load up Google Maps and pick the result that has you taking AirTrain to Jamaica, and then a cluster of colorful names including Babylon, Hempstead, Long Beach, Port Jefferson, and Ronkonkoma to Penn Station.

🍹 True fact: Ronkonkoma isn't a real place!

Once in the baggage area of any of the terminals follow the signs for Ground Transportation and then AirTrain. Board (ticketless) a Jamaica Station-bound AirTrain. Do not board a Howard Beach-bound AirTrain. Once at Jamaica Station, swarm with the others to purchase a MetroCard of at least $5 value. I recommend just getting a $20 (plus $1.4536̅6̅ bonus!!!) card for your time here. The UI will try to create a false distinction between an "AirTrain MetroCard" and a normal MetroCard. Do not be fooled. You simply need a card with at least $5 v

Just about the only thing that'll crash the Erlang VM is running out of memory. Although processes themselves are cheap, a good way to run out of memory is to start an unbounded number of processes from an external signal (such as one per web request), and then make each of those processes hold onto some more expensive resource. If you're not careful about cleanup, you can also leak processes, which compounds the problem. Anyway, nobody's perfect, so to avoid these cases, we use the poolboy library in a bunch of places to handle process pools that handle cleanup and limit the total amount of concurrency to some reasonable amount.

When:

1. all a pool's workers are checked out (by actual organic load/concurrency)
2. some process is leaking pool workers by not checking them back in (rude)
3. the pool supervisor isn't responding (it's deadlocked, bugs, etc.)

you'll see "checkout" timeouts (waited longer than the timeout to check out a worker from the pool):

AWS Lambda allows you to run custom binaries as child processes.

However, if the packaged binary you're running on AWS Lambda uses shared libraries, they may not be available in the Lambda environment. If this is the case, your binary will terminate without any output. In my case, the exit status code was 127, which wasn't very helpful (typically this is "command not found.")

Linux's loader, ld.so, allows you (see manpage) to set an environment variable called LD_DEBUG that will output verbose information while the shared libraries are loaded.

Since Lambda doesn't let you set arbitrary environment variables, you need to set the environment
