  1. Switching IPython to Python 3

    More and more, IPython has become my tool of choice as the ultimate calculator and to try out concepts and code for use in my programs.

    While I generally use the terminal-based interactive shell, notebooks offer more capabilities for integrating text, formulas and graphics.

    With Python 2.7 effectively mostly ...

  2. TeXcalc

    As an engineer, I often do diverse calculations that I want to save in my logbooks which I write in LaTeX. Up to now I’ve either formatted those by hand or used the listings package to include calculations made in IPython.

    One way of making hard to guess passwords is to take random data and encode it with base64 to make it readable. This is what I’ve done in the script.

    To and from hexadecimal (base 16):

    In [1]: hex(100)
    Out[1]: '0x64'
    In [2]: int(0xa7)
    Out ...
