# How Internet Long Tail Helped Me Fixing My Smartphone

I am just more and more amazed by the opportunities offered by the current Internet connectivity: they call it the long tail. It strikes me that just few years ago what I have done would have been extreemely difficult or very expensive … or both. So here is the story of how I was able to fix my Samsung Galaxy S2, the steps I followed and the resources that helped me.

# Understanding Great Circle Arcs Intersection Algorithm

The following material is the result of my attempt to understand the nice example from Jason Davies. I was puzzled about the origin of the algorithm used to find the intersection of two great circle arcs. Google helped and I discovered Roger Stafford’s post in Matlab newsgroup and the relevant Python’s implementation in the Spherical Geometry Toolkit. The algorithm You have two great circle arcs on a sphere, (a) from point (\mathbf{a_0}) to (\mathbf{a_1}), and (b) from (\mathbf{b_0}) to (\mathbf{b_1}), whose coordinates are expressed as longitude (\theta) (positive going East of Greenwich) and latitude (\phi) (positive going North).

# Automatically extracting bomb drops from the Blitz Bomb Census maps

I just finished Blackout by Connie Willis and I was wondering where she did get all the exact times when the air raids of The Blitz were happening. I am curious because I was thinking that a timeline map would give a visual effect of the huge destruction and hard times the Londoners had to go through…so I googled for it and found the following: a nice research blog which uses the Blitz Bomb Census from The National Archivesa blog entry from the Guardian about the first day - and data - of the Blitz over London.
