Check if an email address exists without sending an email. Technique from: http://www.webdigi.co.uk/blog/2009/how-to-check-if-an-email-address-exists-without-sending-an-email/

Check that a particular email address exists.

WARNING:
Checking email addresses in this way is not recommended, and will lead to
your site being listed in RBLs as a source of abusive traffic. Mail server
admins do like it when they get connections that don't result in email being
sent, because spammers often use this technique to verify email addresses.

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

Fetching lyrics in Unix

Fetching lyrics in the command line

Objective: Print the lyrics for the current playing song.

How: We'll create a small bash script to do the fetching for us (using curl) and then we'll display it either in the terminal or in our $EDITOR

Get the current song

First we'll need to get the name of the current song and its artist:
