Batch Download ESA's Sentinel satellite images

The new ESA's satellite Sentinel  data is distributed free using an open data hub.
All you need to do is to register. The data hub provide tools for searching data and creating a cart of products for downloading. Since I'm very lazy, I created a Python client that would download the data once provided with the correct data link or a product list file (that can be easily downloaded from the hub online interface. The code is freely available on GitHub at:

Next step (if time will allow it) is to add an automated data search based on parameters such as location, data type, dates etc.

FFT using pylab

from pylab import *

data,timestep = 10*sin(arange(1000)*5/2.0/pi)+5*sin(arange(1000)*10/2.0/pi),0.01
han = hanning(len(data))
handata = han*data
n = len(data)*50
FFT = abs(fftshift(fft(handata,n)))
freq = fftshift(fftfreq(n,timestep))
plot(freq,2*FFT/sum(han))

ASUS EeePc fan replacement

My 2009 Asus EeePc (model 1005ha) started to make loud noise. I figured it was the fan. With an aid of this YouTube movie (see below) I was able to replace the fan and repair it. Thanks luisfilipe1983!
