Docx (and other Office doc) previewer support for ActiveStorage

Converts all document formats using LibreOffice first to PDF and then to an image, using build-in pdf previwer of ActiveStorage

  • needs: unoconv, a command line tool which uses libreoffice, e.g. apt install unoconv
  • needs a PDF converter, because libreoffice will make a pdf from the office document, Mupdf oder Poppler are already integrated into ActiveStorage, and poppler is free to use, e.g. apt install poppler-utils

How to fix rbenv: version `x.x.x` is not installed

So, you just cloned an existing project's repo and you run bundle install but you got the error: rbenv: version x.x.x is not installed....

What the issue means? The project uses a specific ruby version that you do not have on your system.

Here's how to fix it:

  • Install the Ruby build for the specified version using:
rbenv install x.x.x

Falsehoods programmers believe about time, in a single list

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

  • There are always 24 hours in a day.
  • February is always 28 days long.
  • Any 24-hour period will always begin and end in the same day (or week, or month).
