| | * [[https://en.wikibooks.org/wiki/LaTeX/Presentations#The_Beamer_package|Beamer]] is a LaTeX package for creating presentations. |
| | * You can use it with [[https://pdfpc.github.io/|pdfpc]] to show slides on the overhead projector while reading your notes on your laptop's screen. Create the dual-screen PDF with ''\usepackage{pgfpages} \setbeameroption{show notes} \setbeameroption{show notes on second screen=left}'' and add notes using ''\note{Hello!}''. Then display your presentation with ''pdfpc --notes=left presentation.pdf''. |
| | * If you need a pdf-a validator (e.g. for your thesis), you can use `/lnet/ms/projects/verapdf/checkpdf` in the ufal internal network, which is a wrapper for the verapdf tool. New versions of the specification of exact requirements for submitting theses at the Charles university (called a "profile") appear regularly at https://cuni.cz/UK-7987.html; by default, the tool uses version UK-7987-version1-custom8.xml . |

| | ===== TAR archive mounting ===== |
| | If you work with data consisting of many small files, you **should** store them in tar archives to save inodes. There is a way to mount a tar archive to a specific directory in the simmilar way you mount ISO image. You can use the following wrapper script to //mount// (read-only) ARCHIVE to DIRECTORY: |
| |
| | /opt/bin/tarmount -a ARCHIVE DIRECTORY |
| | |
| | and //umount// when you finish your work: |
| | |
| | /opt/bin/tarmount DIRECTORY |
| | |
| | You can also use the original tool called [[https://github.com/mxmlnkn/ratarmount | ratarmount]] directly through the link: |
| | |
| | /opt/bin/tarmounter |

| * You **should not turn off** Linux workstations at ÚFAL, unless really needed (or agreed with it@ufal). In that case, try the standard ways, and if they do not work, try Ctrl+Alt+SysRq+[R,E,I,S,U,B] rather than plug out power cable.

| | * SysRq has also other interesting uses: For example, if you manage to launch a program that exhausts all RAM, the system starts swapping and becomes unresponsive, you can recover by invoking the OOM-killer by pressing Ctrl+Alt+SysRq+F. |
