Let’s leave aside, for now, the fact that you’ve changed web standards. You’ve been a participant in the first time—in the history of the web, far as I know—that the web development community has taken a feature from an initial proposal to the funding of an honest-to-God native implementation.

Instead, I want you to focus on this: say only ten developers use a native responsive images solution to reduce the weight of just one page apeice by only 500kb, and each of those pages has a barely-significant 5,000 hits per month: those users have been saved almost 24GB of data. A thousand pages saving 500kb apeice, and we’ve saved users an entire terabyte in a month. Now expand that to the entire industry: every web developer; every hit on every page that would otherwise carry with it a huge, wasteful image request, saving megabytes at a time. To those users, the only change is that the web is faster, less expensive, more accessible. For those users, the web is just better.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Earlier, amidst many other tweets about a new css preprocessor, Myth, I tweeted "Avoid snake oil, people. It takes more than a pretty website and a good marketing message. You have to actually deliver code that works." to which @necolas replied "assume your peers have good intentions".

Absolutely. This is sound life advice. I endeavor to do this and the message I wanted to convey to everyone today could have been conveyed without resorting to using such negative phrases as "snake oil". So to the guys at Segment.io and especially to Ian Storm Taylor, I'd like to say I'm sorry. I was frustrated, but that doesn't excuse that tweet.

I'd like to talk briefly about why I was so frustrated.

Even people with great intentions can still do harm. Recently a nice guy decided he would give away a thousand dollars by ["making it rain" dollars at a mall](http://abclocal.go.com/kabc/sto

// data comes from here http://stat-computing.org/dataexpo/2009/the-data.html
// download 1994.csv.bz2 and unpack by running: cat 1994.csv.bz2 | bzip2 -d > 1994.csv
// 1994.csv should be ~5.2 million lines and 500MB
// importing all rows into leveldb took ~50 seconds on my machine

// there are two main techniques at work here:
// 1: never create JS objects, leave the data as binary the entire time (binary-split does this)
// 2: group lines into 16 MB batches, to take advantage of leveldbs batch API (byte-stream does this)
