  * [[:user:yan:aur_repack]]
  * [[:user:yan:virt_browser]]
  * [[:user:yan:archmime]]
  * [[https://shattered.io/|SHA1 becoming obsolete]]
  * MC has blue background so no melatonin for you and you [[https://www.scientificamerican.com/article/q-a-why-is-blue-light-before-bedtime-bad-for-sleep/ | get harder to fall asleep]] after its exposure but [[https://centos-vn.blogspot.cz/2013/12/midnight-commander-color-scheme.html|it can be easily solved]] (or alternatevilely by changinng skin - see mc manual for details)
  * [[https://i3wm.org/docs/userguide.html#assign_workspace|predefined workspaces for different applications in I3]]
  * **molden** configuration file is ~/.moldenrc
  * qcow2 is mounted by three commands - first //"modprobe nbd"//, than //"qemu-nbd -c /dev/nbdx filename.qcow2"//, than //"mount -o ...,offset=$offset ..."// (offset is ussualy computed by partition byte start # * 512 (byte size))
  * [[:user:yan:bluetooth]]
  * [[_user:yan:inspiron|Dell inspiron 5537 battery "feature & overall satisfaction"]]
  * If you're using fish shell application "history" is used for handling of history. If you want to delete some command from history it is good practise to first do "history --delete //command that is better to forgot//" and then delete last history-deletion command.
  * [[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.
  * Book-scanning linux [[https://natecraun.net/articles/linux-guide-to-book-scanning.html | guide]]. Scan [[http://freshmeat.sourceforge.net/projects/scantailor | postprocessing]]. 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

**i can probably help if you need one (or more) of these:**
  * organic synthesis consulting, background literature etc
  * hints for isolation of natural compounds (Capsaicin ? Furanocoumarins?)
  * basic aid for 3d printing
  * basic insight into blender (creating useful *.stl from scratch)
  * basic insight into FreeCAD (creating useful *.stl from scratch, improving UE)
  * start to panic
