I bought a Seeedstudio Xadow recently, and to get it to work with Arduino 1.6.3 was bit of a pain. Long story short, you can find the necessary files along with pithy instructions at my github repo.
The most crucial difference between the files Seeedstudio supplied and what …

I do all my 3D design in Blender, producing models fit for 3D printing. It isn't as hard as it sounds as long as you keep to the following rules:
- Keep consistent scale. For me that means 1 Blender unit = 1 mm
- Use boolean operations on meshes, avoid editing meshes …

Previously we found that PyPy achieves the best performance gain, executing fieldfunc_py in ~6 us. At the end of that article, I mentioned that the C implementation is up to 50x faster, managing the same calculation in ~0.12 us.
The naive conclusion is that the best thing is to …

Recently I found myself looking at the following piece of code and trying to optimise it:
from __future__ import division
import numpy as np
MagneticPermeability = 4*np.pi*1e-7
MagneticPermeabilityOver4Pi = MagneticPermeability / (4*np.pi)
def fieldfunc_py(p, q, moment):
r = p - q
rmag = np.sqrt(r.dot(r))
rdash3 = rmag …

If, like me, you use Nikon's NIS Elements to do fluorescence imaging, you would have also noticed that nothing other than NIS Elements can read the metadata that is saved with TIFFs. ImageJ can't read it, the GIMP can't read it, tiffinfo …

Simply set the language for non-unicode programs to Chinese (PRC) and it will magically work.
N.B. You must have first installed files for East Asia Languages in Languages Tab for this to work.

I subscribe to The Moth, and had previously selected all episodes to be sync'd to my iPhone. Recently I found myself short on space, so I wanted to tell iTunes 11 to stop doing that. Previously, it was a simple case of multiple selection in a list and uncheck, but …

Definitely the Kindle. Amazon offers an amazing service, especially their personal document service's email feature. That is simply divine. Furthermore, Amazon isn't nearly so annoying to use as a non-US citizen. I don't have to use a trick credit card or proxies to purchase ebooks. Amazon just sells them to …

Pixelmator wins hands down. Compared to Pixelmator Acorn is anaemic in terms of features and costs more than twice as much.
Disclosure: I originally got Acorn as part of MacHeist, so I didn't pay full price for it. I did pay full price for Pixelmator.

- I love the fact the screws holding down the battery cover has little flip up handles so you can turn them with just your fingers, and that they are set so that they don't fall out once loosened. This is top quality design. However, the battery compartment door is not …

I used to use Jumpcut a long time ago, and was a big fan of it. At some point, I think around 10.5, it stopped working, and I let it go -- too busy at the time to poke at it.
Recently however my interest in it was piqued again …
