Android fastboot flashing

Here are some instructions on how to successfully flash a new Android System Image.

Preparation

First download and extract the Android System Image that you want to flash. I'll be using hammerhead-mob30h, which is the May security update for my Nexus 5 (2013).

Extract the archive and enter the directory. You'll also want to extract the image-*.zip file as well (image-hammerhead-mob30h.zip in my case), which contains the other img files.

cd ~/Downloads/image-hammerhead-mob30h

iTunes Artist Photos

The iTunes API doesn't provide a way to grab artist images, but the iTunes website uses Open Graph meta tags, which embeds a meta tag with a property attribute value set to og:image. As it turns out, this seems to be the same image used in the iTunes artwork.

The URL structure is similar to the artworkUrl values returned by the API, but what concerns us here is the part I've indicated at the end of the URL.

Download Vagrant boxes manually

In this example, we're going to download the Midnight Sun box.

# The box URL is https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0
# In general, we just take the box URL, and then append the provider URL
# https://app.vagrantup.com/<organization name>/boxes/<box name>/versions/<version>/providers/<provider>.box
wget https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0/providers/virtualbox.box -O box-2.1.0.box

How to make Cygwin use native symlinks

I stumbled upon this cool Cygwin option that allows you to use native Windows (NTFS) symlinks (like CreateSymbolicLinkW in the Win32 API, or mklink via cmd shell). Apparently there's a CYGWIN environment variable that "is used to configure many global settings for the Cygwin runtime system".

One of those options is winsymlinks:{lnk,native,nativestrict}.

if set to just winsymlinks or winsymlinks:lnk, Cygwin creates symlinks as Windows shortcuts with a special header and the R/O
