start new:
tmux
start new with session name:
tmux new -s myname
Magic words:
psql -U postgres
Some interesting flags (to see all, use -h
or --help
depending on your psql version):
-E
: will describe the underlaying queries of the \
commands (cool for learning!)-l
: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)(by @andrestaltz)

Let's say the plugin is at a GitHub URL https://github.com/manasthakur/foo
.
First get the plugin by either cloning it (git clone https://github.com/manasthakur.foo.git
) or simply downloading it as a zip (from its GitHub page).
Adding a plugin in Vim is equivalent to adding the plugin's code properly into its runtimepath (includes the $HOME/.vim
directory by default).
For example, if the layout of a plugin foo
is as follows:
foo/autoload/foo.vim
foo/plugin/foo.vim

While attempting to explain JavaScript's reduce
method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.
JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List
is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

Sometimes you want to have a subdirectory on the master
branch be the root directory of a repository’s gh-pages
branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master
branch alongside the rest of your code.
For the sake of this example, let’s pretend the subfolder containing your site is named dist
.
Remove the dist
directory from the project’s .gitignore
file (it’s ignored by default by Yeoman).
I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).
Hi Nicholas,
I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:
The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
