Sure there are foss qr code generators, I don’t know any at the moment but with a simple google search you should find what you want. About the pdf on a specific page, I think you can add #page={pageNumber} in the url and should open it at the given page.

At work I use firefox, but to be fair we don’t have any firewall or restrictions. Home I use librewolf for privacy reasons.

Well…there are a lot of things I don’t understand, but maybe I’m just weird in that way :)) I don’t understand why some people accept that what they know at this moment is enough and don’t try to learn new stuff and be better tomorrow than they are now. I don’t understand why some people choose to ignore creativity and event think that creative people are childish or even stupid. And also, I don’t understand why lots of people choose to be jackasses and act accordingly to others when it would be so easy do not do this.

I don’t know…I think I always had a passion for it. I always liked tech stuff and liked to play the computers. Built my first site at 13, after that another and another and so on…now I have 10 years of software engineering, worked with multiple technologies and frameworks along the way. Nowadays I work as a software architect at one of the largest companies in my country.

Now I am using fedora, before that I used debian stable.
