ive just heard of an incident where students redirected their books codes to p**n. can i make sure that doesnt happen? also, im using google to generate them, is there a foss alternative as im scared of tracking. lastly, can i make the qr code redirect to a specific page of a pdf as i want people to be able to scan them and immediately land on a specific part
A QR code just links to a URL. If you link to a URL that you own or control, it’ll be fine. The problem comes when people use a link shortener that allows the destination to be changed later, or if they lose control of the domain or its backend.
To make this a bit more precise, a QR code is a link. It’s just a different encoding of text, in a format that’s easy to read using cameras.
What does censoring the “or” in porn accomplish?
nsfw
The word porn doesn’t make it nsfw
I just got fired after reading your comment.

Not exactly, you can read piss shit fuck, however other words like maybe removed, removed, removed, removed may be censored
Edit: didn’t think this one through lmao
W hor e

G**k
N**er
G**k
Damn those geeks.
Okay, now I get it
We’re on lemmy.ml right now
Could be for the sort of awful filters so frequently employed by schools that just block content based on matching a list of banned words exactly, like I used to have in high school years ago. We couldn’t visit a page on breast cancer without an admin override while learning about cancer in the school library as part of an assignment, all because their awful content filter flagged the page as porn for having the word breast in the page.
I worked for a college that banned the word ‘adult’. We had a course called ‘Adult nursing’. You could not access the course list of the colleges own website because of this.
Fun addition, I was the IT tech, I had to spend a ridiculous amount of time whitelisting different domains.
You really should mark your comment as NSFW.
This is a joke people, chill.

This is kind of confusing, or at least leaves a lot of detail out 😆 Did the domain lapse? Did their short-URL account get hacked? In any case, your QR code will just be encoding a URL. Ultimately, any URL can be redirected by someone out there; so it’s just a matter of trusting that whoever has that access won’t act maliciously, and that malicious actors can’t gain access.
also, im using google to generate them, is there a foss alternative as im scared of tracking.
There absolutely are, just search and you should find plenty. Again, though, the QR code is just encoding a URL. Does Google use their own short-URL service for their generated QR codes? Just scan the QR code and look at the URL it encodes. If it’s only the URL you want - not some Google short-URL that then redirects to the URL you entered - then there can’t be any tracking done on it by Google.
lastly, can i make the qr code redirect to a specific page of a pdf
Covered by another commenter already, but for completeness: yes, you just add
#page={n)at the end of the URL, e.g. https://dagrs.berkeley.edu/sites/default/files/2020-01/sample.pdf#page=5Removed by mod
No, its just a coded form of a URL. People just dont know this and use weird online generators / link grabbers. Sometimes these use URL shorteners too, where easy typos can happen
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.
Yeah,
#page={n)works, e.g. https://dagrs.berkeley.edu/sites/default/files/2020-01/sample.pdf#page=5
There is also a PC based offline barcode generator called Zint. I’ve used it a lot over the years. It can generate regular barcodes, QR codes, or other ones. It’s very handy. You can generate using batch files with it also, if you have a lot to do.
as for foss generators, there’s an app on f-droid called Binary Eye for reading and generating assorted bar codes, including qr codes.
