25 Node.js Nuggets

Node.js

My last Nuggets post, “50 Linux Resources for Developers” was pretty well-received, so I figured I’d try to do the same thing I did there for Node.js. Hopefully something here gives you some inspiration to make the next great Javascript app. It’s not meant to be an all-inclusive guide to learning Node, but more of a look at my journey with Node and some things I’ve found useful which you might find useful as well.

For a little background, here’s the synopsis of Node.js from their website:

Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

7 Small Reasons to Love Vim

Techiavellian on July 8, 2014

These are some cool things you can do with Vim that save time and can help prevent mistakes from mouse selection. They’re mostly little things, but altogether they make up an editing environment that I simply love.

1. NERDTree (Docs) file deletion

<Ctrl-L> to open NERDTree, hjkl to move, mdy to delete

2. Easymotion (Docs). Check out their example GIFs, and you’ll never see movement with the keyboard the same again.

3. Executing shell commands without changing windows

:!ls ~  :!rm -rf ~/old.txt

4. Deleting everything inside quotation marks, function blocks, parameters lists, or tags

di" di' di` di{  di(  di[  di< (Delete text within first matched pair)
dit   (Delete text inside first matched "tag" e.g.: <div>TEXT</div>)

5. Selecting/deleting large blocks of text

Selecting: V <Ctrl-F> (page by page)
           V 500j (select 500 lines)
Deleting: d500d (delete 500 lines)

6. Searching Dash (paid app, but worth it) using dash.vim (Docs)

:Dash each underscore  :Dash Vim

7. Deleting only blank lines on either side of the cursor

In ~/.vimrc:
" Ctrl-up/down deletes blank line below/above, and Ctrl-k/j inserts.
nnoremap <silent><C-Down> m`:silent +g/\m^\s*$/d<CR>``:noh<CR>
nnoremap <silent><C-Up> m`:silent -g/\m^\s*$/d<CR>``:noh<CR>
nnoremap <silent><C-j> :set paste<CR>m`o<Esc>``:set nopaste<CR>
nnoremap <silent><C-k> :set paste<CR>m`O<Esc>``:set nopaste<CR>

You wouldn’t have a maximum account balance, would you?

I recently paid for something online using what I considered a secure online payments processor, and they asked that I provide a password to create an account to complete the transaction. You will understand in a second (if you don’t already) why I was so angry when, a few seconds later, I got this:

NOOOOOOOOO

Noooooo

I couldn’t believe it. Please enter a shorter password.
