  1. Using a scanner for macro photography

    Although you wouldn’t guess it from the contents of this blog, my day job involves the design and production of products from fiber reinforced composites. A lot of my projects fall under non-disclosure agreements, so I cannot discuss them here.

    What I can do is share some of the methods I’ve developed over the years. One of those is using a desktop scanner to make close-ups.

    Introduction

    The purpose of this program is to calculate some properties of fiber-reinforced composite laminates. It calculates:

    • engineering properties like \(E_x\), \(E_y\), \(G_{xy}\)
    • thermal properties \(\alpha_x\) and \(\alpha_y\)
    • physical properties like density (\(\rho\)) and laminate thickness (\(t\))
    • stiffness (or ABD) and ...
  3. Python bindings for libmagic

    This documents how I installed Python bindings for libmagic.

    There are actually different bindings for libmagic. One set is part of the original distribution. It can be found in /usr/src/contrib/file/python/. But in my opinion it is somewhat cumbersome to use and not very Pythonic.

    The implementation from ahupp/python-magic in Github feels more natural.

  4. Windows 8: the infinite yak-shaving

    So I got a call from a friend who’s ms-windows 8 laptop was wedged.

    Having set the machine up for him, I felt obliged to help, even though troubleshooting ms-windows ranks pretty on the bottom my list of favorite activities.
