So you want to modify the text of a PDF by hand

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Cómo trabajar con git branches

Workflow con git

Para este proyecto seguiremos la metodología de tener una branch principal master (equivalente a release en otros proyectos), una branch dev (o development) para comprobar que todo funcione antes de enviar los cambios a master y múltiples "feature branches" para que cada colaborador pueda enacrgarse de una tarea definida, trabajarla y probarla a gusto antes de reunir los cambios en dev. Para más detalle y ejemplos pueden usar de esta lectura la sección Feature Branch Workflow.

Summary of 'Clean code' by Robert C. Martin

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.


General rules

  1. Follow standard conventions.
  2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
  3. Boy scout rule. Leave the campground cleaner than you found it.
  4. Always find root cause. Always look for the root cause of a problem.

Design rules

Get memory info for all GPUs in Numba

gpus = cuda.gpus.lst
for gpu in gpus:
with gpu:
meminfo = cuda.current_context().get_memory_info()
print("%s, free: %s bytes, total, %s bytes" % (gpu, meminfo[0], meminfo[1]))

mkdown

What is this?

Mkdown renders Markdown GitHub gists with alternative CSS. Use it to elegantly share gists written in Markdown.

How do I use this?

To create your own mkdown URL, append the gist ID in a URL of the form: http://mkdown.com/{GIST ID}. The gist ID is the string at the end of a gist URL.
