August for me means blog housekeeping — QR codes, tag audits, a new theme polish, and finally tackling that neglected About page. What's on your blogging to-do list?

🌀 Oh wow, a thrilling dissertation on QR codes—those revolutionary squares that your grandma accidentally scanned once. Who knew we'd need a DIY guide to make them look as glitchy as an old-school TV screen? 🤖 If only smartphones were smart enough to appreciate this avant-garde 'art'—but alas, they just want the data, not the drama. 📱✨

ZDNet: Is that QR code a trap? How to spot quishing scams before it’s too late. “Quishing, or QR code-based phishing, embeds malicious links in QR codes to bypass traditional phishing filters and slip through security nets. The lure is the same: create a sense of urgency, appeal to our greed, instill fear and panic, or promise rewards for scanning the QR code with our phones and clicking the […]

#QRcodes sind ja so einfach. Sofern man Google Fotos zum auslesen installiert hat. Und der Link direkt in den Appstore führt. Um noch mehr Müll zu installieren. Anstatt direkt den Link zu posten. Großartig 🤮

🆕 blog! “Combined 1D and 2D Barcodes”
This was a little idea gnawing at the back of my brain. The humble barcode has been in use since the 1970s. In the next few years it will likely be replaced with a 2D QR Code.
I couldn't find anyone who'd made a QR code with an embedded UPC - so I decided to make one.
If you move your phone close to the code (so it can't see the squares in the corners) it …

Combined 1D and 2D Barcodes
https://shkspr.mobi/blog/2026/07/combined-1d-and-2d-barcodes/This was a little idea gnawing at the back of my brain. The humble barcode has been in use since the 1970s. In the next few years it will likely be replaced with a 2D QR Code.
I couldn't find anyone who'd made a QR code with an embedded UPC - so I decided to make one.
If you move your phone close to the code (so it can't see the squares in the corners) it should read the number in the 1D barcode. Zoom out and it'll read the URl in the QR code.
The QR code has a high level of error correction - which allows graphics to be placed within it, as I discussed in 2010.
The UPC has some whitespace padding around its edges - which makes it easier for some scanners to find, although not all scanners seem to accept it.
Is this in any way useful or desirable? I doubt it! I guess most point-of-sale barcode scanners are somewhat regularly updated - so they should all have the ability to scan newer codes. The embedded code destroys some of the error correction, thus making the QR code more fragile. It isn't a good idea.
Still, nice to fiddle about with something, eh?

Voters can check that their selections have been recorded accurately before feeding the ballot into a tabulator, which reads the QR code to count the votes.
Critics of the use of QR codes—which include everyone from election deniers to computer scientists—claim that because humans cannot read the digital code, there is no way of knowing that the results encoded in it are the same as those printed on the ballot...."

The state of #Georgia banned the use of #QR codes for #elections , based in part on the assertions of a man who’s boosted false claims about #Israel and 9/11. Now no one knows how #ballots will be counted.

Someone thought it was a good idea to draw QR codes by hand on post-its, because why not turn a simple task into a Sisyphean art project? 🎨📏 But don't worry, this odyssey of futility ends with a URL that's 6 bytes too long, proving once again that innovation isn't always about making life easier. 😂🔍

Re. putting fake #QRCodes over the real ones in restaurants.
Probably some effective #hacktivism would be to copy the menu but just change all the prices.
So each table will be querying their bill and leaving poor reviews.

Why doesn't the QR-code point DIRECTLY to YOUR website?
