Some time ago I used an online tool to generate some QR codes with a contact URL so I can put them on my luggage.
Now I got a new bag and need a new QR code for it. As I don't remember the online tool I used years ago, I decided to write my own tool.
Thus say hello to qr-bag. It's a commandline tool written in Go to generate QR codes for URLs with a little logo in the middle.
The code for it is mostly a wrapper around the go-qrcode library which does all the heavy lifting.
Just discovered the text-decoration-color CSS property and added it to the style on the blog:
a:hover {color: #454545; text-decoration: underline; text-decoration-color: #26C4FF;}
This causes that when you hover over a link in a post, the underline is not in the same boring gray as the text but lights up in a nice color :-)
(not to be confused with the hacky colored underlines in the righthand navigation bar, where I use a colored border-bottom to achieve a similar effect since 2002)
It's time again to do some cleanup of my blogroll before the links start to turn into 404 errors :-)
Removed:
Following in the trend of replacing tables, I've revived the old statistics page.
Now using less markup as it is built with <div> and CSS only (the display: inline-block; property was particularly helpful).
(the Jekyll/Liquid templating to generate the data for it looks quite horrific though…)
Over the last couple weeks I slowly replaced the various <table>-based layout elements of the blog with more modern HTML elements.
And finally this afternoon the work was completed with the last <table> element gone.
Visually there should be almost no differences, but in case something looks strange just let me know :-)
(and yes, style-wise everything is still using the pixel-based layout from 2002, one day this might change as well…)
To provide basic dark mode support for the blog, I added the following lines of CSS:
@media (prefers-color-scheme: dark) {
html { filter: invert(1) hue-rotate(180deg); }
img, video, iframe { filter: invert(1) hue-rotate(180deg); }
}
If the browser/OS has dark mode enabled it will invert the colors and rotate the hue to achieve the dark mode effect.
The whole operation is applied a second time on images, videos and frames to avoid that they have their colors distorted.
You can get a preview by using the developer tools of your browser to enable dark mode :-)
The code is inspired by the post here, and then extended to provide a CSS-only solution by leveraging the color-scheme CSS property.
Some very fine Drum and bass. Recently got to experience two of them live (Sub Focus & 1991), and have plans to see Dimension next :-)
Especially like the little The Prodigy mixin starting at 1:04:30 🥳
As mentioned before, I'm a supporter of the Cool URIs don't change approach.
Thus I try to keep all the URLs of this blog working (or at least make them redirect to the new place where the content is located).
Not always an easy task with old domains and multiple blogging engines accumulated over the years.
To help me with that (and ensure I don't break anything when updating a 10+ year old mod_rewrite config) I created a short Bash script to test the redirect behavior.
It contains a list of URLs and their expected redirect target, goes through them with curl and checks that the correct Location: header is returned.
As it might be useful for others in similar situations, the script can be found here.
I miss human curation — Where are my internet friends? And where are their weird blogs? (via)
While adding some new alias functionality to my setup, it repeatedly failed with an error similar to this, despite my configuration changes:
Recipient address rejected: unverified address: host XXX[XXX] said: 550 5.1.1 <foo@bar.com> User doesn't exist: foo@bar.com (in reply to RCPT TO command);
Turns out that the negative verification result is cached and the cache is not reset during a reload/restart of postfix.
Thus it must be cleared manually like this:
/etc/init.d/postfix stop rm /var/lib/postfix/verify_cache.db /etc/init.d/postfix start
