Handwritten title ‘Early Markup’ above a photo of an ancient Egyptian wall relief showing painted hieroglyphs, birds, and symbolic figures in muted reds, greens, and golds. Some hieroglyphs are contained within a cartouche.

Gave a GitHub, GitHub Copilot, VSCode demo to fellow Product Managers recently, wanted to cover Markdown files, so needed to cover the concept of Markup, I might have gone a little too deep.

I now have a drone (my first), so all my future photos will probably be some variation on this one (which was taken over Church Lench, Evesham, UK)

Apparently, the new Trump-class warship will use an AI based on Trump’s own personality. There’s only one possible problem…

Photo editing using Gemini Examples of photo editing using the new Nano Banana model that's part of Google Gemini.

You can colourise using the Nano Banana model that's part of Gemini as well, it's probably its best feature (that no one mentions), couple examples here: onlyrss.org/posts/nano-b...

Here's one for your "catalogue of deception/manipulation manual" etc. This is from a hotel check-in process. The marketing opt-out is hidden behind a "click here" link. And there was me believing that links were meant for navigation 🤔.

As an "older" brit, I remember when it was cheaper to buy my gadgets from the US… the DJI Osmo Pocket 3 is £489 ($650) in the UK. In the US, prior to April it was $519, it's now $799. Americans are soon to be one of the most heavily taxed peoples on the planet.

Trump only has one requirement when it comes to hiring people i.e. loyalty to Trump. Intelligence/knowledge are not only not required, I suspect they are actively discouraged.

When Bike? - Burghfield A page designed to let cyclists (or walkers) who live in Burghfield, know the best times to go for a bike ride (or walk). It does this for 1, 2, 3, 4, and 5-hour slots.

Vibe-coded myself a "when should I go for my bike ride?" app. Written in Python, uses a weather API (visualcrossing), Google Gemini AI, and #Datawrapper (for charts). Only useful for people who live near my village though! onlyrss.org/apps/when-bi...

There's a nice little feature on the PostPark screenshots/mockups tool, you can get a GitHub commit history by just entering a GitHub username. From the nav: Templates > GitHub Contributions. postspark.app/github-contr...

Trump shocked to discover that China knows about big numbers as well. But all is well, Trump has now found out about numbers biggerer than 100, so now there's nothing the Chinese can do, Trump confident that the Chinese don't also know about numbers biggerer than 125.

@kevinpowell.co I just dumped some HTML & CSS into Claude and asked it to sketch and annotate the layout. It output the following SVG, which (as a CSS novice) I think is kinda useful. Not sure how well it would work with more complex layouts.

Trump says Ukraine should have "done a deal" with Russia. Exactly the sort of comment I would expect from someone who conveniently developed "bone spurs" which excluded him from Vietnam. Should Europe have done a deal with Nazi Germany?

Now this is something I can get behind. There's a lot of wisdom in Netflix's Castlevania.

In Chrome v133 (i.e. the next version) you can use `atrr()` in CSS to pass HTML attributes to CSS as values—not just strings. And then use them to define parameters such as lengths etc. In this example the bar lengths are in the HTML. No JavaScript was hurt during the creation of this bar chart 😆

Americans wanted lower inflation, looks like they'll have to settle for a US flag on Mars. Seems logical to me 🤔.
