LaTeX tip & tricks

I recently discovered the "trim" option of the includegraphics command :

\includegraphics[trim=Wcm Xcm Ycm Zcm]{image-file}
%left bottom right top

Will remove Wcm on the left, Xon the bottom side, Ycm on the right side, and Zcm on the top side. Be careful when trim AND angle are used at the same time !

LaTeX template pour document littéraire

Having to edit a document of a friend studying "art history" and "english language", I created this LaTeX template after some research on the bibliography styles needed for those fields. The bib style needed was : MLA. The default MLA install of LaTeX didn't match what was expected, and I found mla-good.bst. You can download it here : http://www.reed.edu/cis/help/latex/images/mla-good.bst.zip or here : http://pastebin.com/bBg7CUkM (and others styles : http://www.reed.edu/cis/help/latex/bibtexstyles.html).

Install NetBSD via clef USB

Voici le challenge :

créer une clef usb bootable en NetBSD, en n'ayant qu'une seule clef dispo et pas de machine netbsd sous la main. Le principal problème est de formater la clef USB dans le bon format (et pas de mkfs dispo pour ce systeme de fichier BSD)

Solution trouvée :

booter netbsd-Live en virtualisé dans Qemu pour transférer vers le disque dur virtuel de Qemu les fichiers à copier sur la clef usb, puis formater la clef usb et y remettre les fichiers de boot.

Nettoyer les metadonnées d'images

j'ai pour cela trouvé jhead :

jhead -purejpg [img.jpg]

jhead is used to display and manipulate data contained in the Exif header of JPEG images from digital cameras. By default, jhead displays the more useful camera settings from the file in a user-friendly for‐ mat. jhead can also be used to manipulate some aspects of the image relating to JPEG and Exif headers, such as changing the internal timestamps, removing the thumbnail, or transferring Exif headers back into edited images after graphical editors deleted the Exif header. jhead can also be used to launch other programs, similar in style to the UNIX find command, but much simpler.
