Essential JavaScript Links

A curated list by Eric Elliott and friends. Suggest links in the comments below.

This is a very exclusive collection of only must-have JavaScript links. I'm only listing my favorite links. Nothing else makes the cut. Feel free to suggest links if you think they're good enough to make this list. The really curious should feel free to browse the comments to find other links. I can't guarantee the quality of links in the comments.

Full Disclosure

Some of these links are affiliate links, meaning that if you make a purchase, I might earn a little money. This has absolutely no bearing on whether or not links make the list. None, whatsoever. However, it does allow me more resources to fight poverty with code. Every little bit counts.

// This is a class that attempts to stop you accessing variables outside a lock.
//
// It does not do a perfect job, but can catch some common kinds of mistake, in
// particular when you accidentally try to work with objects inside closures that
// end up running later, outside the locked region (or in a different thread).

// EXAMPLE

val bank = ThreadBox(object {
    val accounts by arrayListOf(10, 0, 0, 0).guard()

-- PostgreSQL cheat sheet

--postgres is set up to use local.6 which is syslog'd to sflog001
--slow query log is /var/log/localmessages
--config files are always in /data/friend/*.conf

--vacuums are set via cfengine, we use both manual and auto.  vacuums/analyze help with frozen id's being recouped, and thus TX'id's not going over 2b thus causing massing shutdown/reset.  Fix it to exp/imp high TX tables.

--to log into psql:  psql -U postgres -d <DB> (usually friend)
