• Manuel Matuzović ☛ Revisiting Fundamentals - Semantic lists for Improved Accessibility

  Whenever I visit any website, I have formed the habit of checking for any accessibility issues and delving deeper into the HTML code structure. One apparent thing is that a large number of sites are characterized by non-semantic code structures that result in inaccessible sites.

  One common culprit that I constantly come across is poorly marked-up list structures. From having list elements made with the paragraph elements to having headings, div, or span elements as direct children of ,

  , or

  elements.

• Hunor Márton Borbély ☛ Day 17: How to Draw Text Along a Path with SVG

  Drawing shapes is not the only use case for paths. We can also use them to render text along an invisible path. We can define a path in the definitions section and use it in a textPath element to make the text go around the circle. Here we use arc again, but you can use any other path and the text will follow the stroke.

• Hunor Márton Borbély ☛ Day 18: How to Animate Along a Path with SVG

  Another fun use of paths is to create animation paths. This method is not SVG only. We are using the offset-path CSS property here that works for any other HTML element as well. But if you check the value of this attribute, you see that we define a path the same way as we do for an SVG.

• University of Toronto ☛ Prometheus's group_left() and group_right() operators

  I'll start with the motivating story. Suppose, not hypothetically, that you have some Bind nameservers and a Prometheus environment, so you're monitoring those nameservers with the Bind exporter. One thing the Bind exporter does is provide the DNS SOA serial number for every zone Bind is configured to be a primary or a secondary for. If you have a primary and some internal secondaries (as we do), you'd like to be sure that your secondaries have the same DNS SOA serial numbers as your primary does. Writing an alert expression for this requires using one of PromQL's matching operators for many-to-one matching, since you have more than one secondary and one primary. However and speaking from recent personal experience, it's surprisingly easy to gloss over the details of the expression you want, especially if you start out with only one secondary. Since I've now stubbed my toes on this repeatedly, I'm going to write down in one spot the matrix of possibilities.

• Connor Tumbleson ☛ It's Relative

  A few weeks ago my 2019 Hyundai Sonata seized again on the way home from trivia - this time I was pretty lucky to abruptly coast/stop in a turn lane. This at least kept me out of blocking traffic even if multiple times someone pulled in behind me and honked at me. I don't understand what people think a stopped car with hazards on means and what honking will accomplish.
