# E-scripts sobre o material do André Nepomuceno (sobre Python).
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

Oi André!
Eu ainda uso o LaTeX _meio_ como dinossauro... eu sei usar o Overleaf
um pouquinho, mas eu tenho uma instalação inteira do TeXLive no meu
computador e eu costumo rodar o pdflatex e o lualatex "localmente"...
Eu consegui baixar a fonte do "Python_basico" e quando eu rodo
pdflatex presentation_test.tex
o pdflatex dá erro no slide 118. Vou copiar o final do log aqui:

?
e vou copiar um trecho da fonte do seu slide 118:
\begin{frame}
\frametitle{Gráficos}
No exemplo anterior, o Spyder mostrará o gráfico no console IPython.
Para abrir uma janela independente (e editar o gráfico), o Spyder deve
ser configurado da seguinte forma:
\newline
Ferramenteas $\,\rightarrow$ Preferência $\,\rightarrow$ Console
IPython $\,\rightarrow$ Gráficos
\newline
Na aba Gráficos, selecione saída: \textbf{Automático}
\newline
Quando rodar o seu programa, aparecerá na tela uma janela semelhante a
figura abaixo.
\begin{center}
\includegraphics[scale=0.3]{plot_example}
\end{center}
\end{frame}
O diretório images_python/ tem um monte de ".png"s e um ".jpeg" mas
ele não tem nenhum arquivo com nome começando com "plot_example".
Eu posso dar um jeito do pdflatex não tentar incluir essa imagem, mas
talvez isso seja um erro que você queria consertar...

Everyone should, at some point, read The Unix-Haters Handbook. A great
deal of it is outdated or simply wrong, but it does have a running
theme of a prediction that has largely been borne out: people assuming
that all Unix's flaws are actually virtues and that if you don't think
so, then you Just Don't Get It.

The problem here is that most unix tools (ls being the exception) do
double duty, they both emit output for other programs and output for
the user. Which one you get and how the user output is presented being
controlled by flags.
If you want them to only emit data in a standardized format you are
implicitly cutting out the user.
https://www.joelonsoftware.com/2003/12/14/biculturalism/ ***
What are the cultural differences between Unix and Windows
programmers? There are many details and subtleties, but for the most
part it comes down to one thing: Unix culture values code which is
useful to other programmers, while Windows culture values code which
is useful to non-programmers.
