How far can you enhance an image or video before you cross the line into manipulation? The UK is currently prosecuting two men accused of a crime. Part of the prosecution's evidence is a video. In showing it to the jury, the prosecution have said: the two minute and 41 second-long video is "extremely dark" but the "unmistakeable" noise of a chainsaw can be heard followed by the sound of a tree…

I have a simple rule of thumb when it comes to news reports. The real story is always in the penultimate paragraph. Let's look at this inflammatory headline: Woman’s 'spree' after $158k banking error, refuses to return pensioner’s life savings An Auckland beneficiary is under investigation for an alleged “spending spree” after $158,000 was mistakenly transferred to her account. […] pensioner lo…

Consider these two HTML elements: <div class="a b">…</div> <div class="a b">…</div> Is there any semantic difference between them? Is there any way to target one but not the other? In other words, are they logically different? I think the answer is no. On every browser I've tested, both are the same. Whether using JS or CSS, there's no difference between them. You could replace every \n wit…

I like to highlight bits of code on my blog. I was using GeSHi - but it has ceased to receive updates and the colours it uses aren't WCAG compliant. After skimming through a few options, I found Tempest Highlight. It has nearly everything I want in a code highlighter: PHP with no 3rd party dependencies. Lots of common languages. Modern, with regular updates. Easy to use fun…

My wife and I run OpenBenches - a crowd-sourced database of nearly 40,000 memorial benches. Every bench is geo-tagged with a latitude and longitude. But how do you go from a string of digits to something human readable? How do I turn -33.755780,150.603769 into "42 Wallaby Way, Sydney, Australia"? Luckily, that's a (somewhat) solved problem. Services like OpenCage, StadiaMaps, OpenStreetMap,…

HTML elements can have attributes. For example id, class, src, alt, and many others. These attributes can contain values - an img element's src attribute has a value which is a link to an image. An id attribute's value is a single string. But some attributes can contain multiple values. Here's a thought experiment for you. Consider these two HTML elements: <p class="alpha bravo charlie">………</p> …

The faithful old GeSHi Syntax Highlighter hasn't seen an update in a many a long year. It's a tried and trusted way to do server-side code highlighting - turning a myriad of programming languages into beautiful HTML & CSS. A few weeks ago, I noticed someone had proposed an update to its HTML rendering. The changes were mostly adding in new element names. PHP has been updated several times…

I think I mostly agree with everything this book is saying, but after almost every paragraph I found myself scribbling the same note "Yes! But what action should I take though?" The author has an excellent and accessible way of showing the problems caused by the Climate Crisis - but the "action" part is mostly missing. Take this example: So something you can do right now to tackle them is to…

What if the Discworld's Assassin's Guild existed in the real world? That's it. That's the plot. Go to a university where they'll teach you to be a better class of murderer. The first half is excellent. Chuckles all the way through. A heady mix of every boarding-school novel you've ever read, and funny little twists and turns. Lots of the dialogue is straight out of Terry Pratchett (and I can't…

The gadget wizards at Benfei know that I'm a sucker for any sort of USB-C gadget. So when they offered to send me their micro-hub to review, how could I refuse? It is dinky! Here's what you get for your tenner USB-C PowerDelivery HDMI USB-A Frankly, I'm impressed that they managed to fit that much in! If you'll excuse my lacklustre photo-editing skills, here are the two output ports: …
