Convert images to pdf

To convert a set of images in a pdf in comand line.

sudo apt-get install imagemagick

convert -compress jpeg * outputFile.pdf

 This will compress you jpeg images but if you don't want that your images will be compressed the may be will e usefull another tool called img2pdf. I didn't tried it yet , may be when i need it. For the moment convert comand it's usefull for my pourposes.

It's usefull, isn't it?

But if you really want to use a graphical interface you can try gscan2pdf that have other utilities like ORC (Optical Character Recognition)

Firefox Profiles

Firefox profiles are useful to separate diferent digital identities of one self. Each one stores the personal information of each identity you choose like cookies, accounts, passwords, navigation history, preferences, etc. This is useful to separate my work and personal life.

To create a new profile just run in a console > firefox -P
And this will open the profile window that allow you create, rename or erase your profiles.
The only limitation that i found is that you can not open two profiles at same time, that is really a shame.

Using Lubuntu i did two shortcuts on desktop, and i modified them to launch different profiles. I changed the comand firefox %u to firefox -P nameprofile.
