I really really hate QR codes.

@mildpeach @sundogplanets I feel like the second point onwards could very well be true for any URL you encounter in the wild.
A good QR scanner app will display what it read and lets you choose what to do with that information.
@phl @mildpeach @sundogplanets yea, just turn off "open immediately" or whatever your setting is

I really really hate QR codes. But a lot of people really like them. And they're useful during a talk for the people who really like them (I'm also including the text of the link, though, dammit!)
But... I have never done this before, and a lot of the "free QR code generators" look kind of scammy and I don't want to give people weird viruses or spam. So... fediverse, help!

@sundogplanets if you are one of those astronomy folks who dabbles in using python on the side, to plot data or ephemeris position stuffs... there are a few libraries for python one can use to create QR codes. No online interaction needed, except to install the library.

1. Choose 'Other' on the left.
2. Click "Generate QR Code" and drag it into the "Recipe" box in the middle.
3. Adjust settings if desired.
4. Paste or type your text into the "Input" field on the top right.
That's it. You can even download the page and run it offline since it's all in your browser.
Also, LibreOffice can do it: https://help.libreoffice.org/latest/en-US/text/shared/01/qrcode.html -

@sundogplanets Also was going to mention LibreOffice. But @Vivaldi browser has a QR generator built right into the URL bar. Super handy.

Thanks @sundogplanets for the pointer, very useful !
There exists alternatives like this simple programmatic approach offered by
https://pypi.org/project/qrcode/
Once installed, it’s a single command like ˋqr "Some text" > test.pngˋ

And you are right @sundogplanets - QR codes really are everywhere these days. What I appreciate, though, is how their ubiquity stems from the inventor’s decision to open-source the technology. It’s a rare example of how sharing an idea can lead to its widespread adoption and utility:
-
What OS are you using? Should be able to get a generator that runs locally with no web needed.
@dlakelan @sundogplanets
All OS that can run LibreOffice. Local, FOSS, no Google, no web needed.LibreOffice, because you wanted to get rid of Microsoft 365 Slopilot crap anyway.

I have a QR generator I wrote (using ZXing libraries). It is written in Java, & runs locally on your system. There are Debian packages, but also an installer for other systems (e.g., MacOS, Windows, etc.). You should install openjdk first. The Debian packages will configure the system to recognize icons, etc., but for other systems, I just provided the files as I had no way of testing that. It can also decode QR codes so you can see what a URL is.

There are plenty of good QR code generators. I use
https://www.qr-code-generator.com/But you are right to be wary - especially when reading QR codes. Make sure that your QR code reader is one that lets you look at the URL first, not one that just loads up automatically. Then you can see that the website being loaded is the one that you are expecting. People have been known to paste fake QR codes over real ones in public places, for example.

"Make sure that your QR code reader is one that lets you look at the URL first, not one that just loads up automatically.

I disabled the included code reader on my Android phone.
Some 3rd party Android coder reader apps on Playstore have had spyware or malware. -
@sundogplanets a lot of them include a url shortener which makes for simpler QR codes that scan more easily... I always used bit.ly in the past, it was fine, and gave some useful stats. But it has been a long while and I got my own shortish domain so just started using local software instead. If you just want straight up QR code generation then QR Code Monkey works fine too IIRC.
@yvan @sundogplanets
URL shorteners are evil because they hide the destination. Such links are now forbidden on many forums. I think invented for Twitter when it was stupidly only SMS size messages.I always preview a QR code and never go to shortened links.

@raymaccarthy I think "evil" is a bit strong... they're effectively just a HTTP redirect. But I totally get the issues with the effective obfuscation of the target URL and am aware that has been used for nefarious purposes. There is no good reason to be using them on things like forums where there are no character limits - that's suspicious behavior! Blocking them on such sites makes sense.
Their origin is certainly in sending URLs in short text formats - be that early Twitter or SMS/text messages. Still useful for the latter.
For QR codes a shorter URL means a simpler QR code. A simpler QR code is both more robust and better to scan from distance (depending on print/display size of course, but especially for if they're going to be on slides at a talk.)
These days I'd expect most good QR apps should automatically preview the redirect target URL. On desktop I use
wget -Sto check the targets of any suspect short URLs.
