 +  * [[https://www.virtualbox.org/ | Oracle VirtualBox]] [[https://www.virtualbox.org/manual/#vrde | VRDP ]] support [[https://www.virtualbox.org/manual/#otherextpacks | can't be run ]] at the same time as VNC extpack. Quick resolution fix (very helpful during VRDE session): $vboxmanage controlvm <machinename> setvideomodehint <x-resolution - for example 1900> <y-resolution - for example 950> <color depth - for example 32> 
 +  * [[http://www.lucob.sk/sites/default/files/323_pdfsam_TK1_EN_LR_2013.pdf | VDE 0295 ]] - norm for conductors structure - good for a calculation of resistance of common conductors. 
 +  * Sometimes printers with CUPS needs to be switched from "ipp:" to "lpd:" [[http://forum.support.xerox.com/t5/Printing/Unable-to-add-document-to-print-job/td-p/195039 | original idea]]. In my case <code> lpd://"ip-address"/wsd </code> worked flawlessly.

I prefer djvu format - can be bundled by [[https://github.com/ashipunov/img2djvu | img2djvu]] but [[http://freshmeat.sourceforge.net/projects/gscan2pdf | gscan2pdf]] also works and can do PDF which are bigger and slower to make (both OCR capable). 
 +  * [[https://fishshell.com/docs/current/tutorial.html#tut_path | add something to the PATH ]] in fish fashion in the [[https://fishshell.com/ | fish shell]] 
 +  * checking for hash in known_hosts - ssh-keygen -lf .ssh/known_hosts | grep whateva
