Continuing LibreOffice Shortcuts poster, here's educational poster I made to spread LibreOffice's ODT - ODS - ODP to all people in all countries. These formats are known with the name Open Document Format and these are better than Microsoft's. The goal of this poster is to invite people to change their habits of saving as DOC - XLS - PPT formats into saving as ODT - ODS - ODP formats which are better. This poster is an English adaptation of my Indonesian version few years ago. I encourage you to place this on your schools, offices, websites, blogs, social media, and other places. You are free to adapt and share it with your own language. If you are curious, download LibreOffice application here for Windows, macOS and GNU/Linux. Okay, now let's share once again!

This is my list of GNU/Linux tools for academic, educational, and research purposes which all are free software. I tried to pick up choices as simple as possible here just to represent every basic category and further I hope you could see more alternatives if you want. I also listed several specific tools like GNU Octave and Parallel which are proven to be useful for certain researches. On the other hand, I deliberately did not list LaTeX tools here as I already chosen LibreOffice for that category. I made every proprietary software name italicized here so you can spot them on easier. Happy researching!
