I remember seeing the original "A new decentralized microblogging platform" on HackerNews back in October 2016. A few weeks later, I joined - becoming the 7,112th user. As the years went on, my use of it waxed and waned. I started cross-posting to both Mastodon and Twitter. Gradually, I started spending more time on the Fediverse. Once Elon shat the bed on Twitter, I moved over completely. And, you know what, I don't regret it for a second. I've found a lovely community of people. I get my…

I've responsibly disclosed a small security issue with Mastodon (GHSA-8982-p7pm-7mqw). It allows a sufficiently determined attacker to use any Mastodon instance to redirect unwary users to a malicious site. What do you think happens if you visit: https://mastodon.social/@PasswordReset/111285045683598517/admin? If you aren't logged in to that instance, it will redirect you to a 3rd party site. Try opening it in a private browser window. Here's another, less convincing, demo: …

As the Middle-East convulses in yet another bloody war, and with no end in sight to the barbarity, we're all looking for a way to understand the horrors unfolding. So I went searching in the past. What set the seeds of today's conflict and was there any way to prevent it? This is a dispassionate and, it has to be said, dry look at how the British intelligence agencies operated in the region during the aftermath of the 2nd world war. The books makes the compelling case that the UK's obsession …

All USB-C cables are equal. But some, as the saying goes, are more equal than others. This little gadget from Plugable is a fantastic bit of kit. Plug your USB-C power supply into one end of the gadget, plug the gadget in to your laptop, phone, or any other USB-C device. Watch the screen to see how much power is flowing.

Imagine a world with inter-city rockets, where tourists still use film cameras. Where self-driving trucks sport a wide array of sensor apparatus and record all their data onto miles of magnetic tape. Where the latest Androids are life-like and can perfectly clone a dead man's speech, yet are powered by punch-cards. People make video calls from public booths which eagerly accept coins as payment. At the heart of nearly every story is paranoia and poor mental health. Perhaps I am a robot? Or…

Yesterday I wrote about a lazy way to implement a manual dark mode chooser. Today I'll show you a slightly more sensible way to do it. It just uses CSS, no need for JavaScript. Here's a scrap of HTML which present a dropdown for a user to choose their colour scheme: <select id="colour-mode"> <option value="">Theme Selector</option> <option value="dark">Dark Mode</option> <option value="light">Light and Bright</option> <option value="eink">eInk</option> </select> It will look…

I'm not saying this is a good way to make a dark mode website. I'm not even saying it's a sensible way to do dark mode. But I'm pretty sure this is the laziest way of getting dark mode on your site. And it is all done with less than a handful of CSS rules. It relies on the new-ish :has() CSS pseudo class and the positively ancient filter() CSS function. Here's the code in all its glory: body:has( > #dark-mode-checkbox:checked ) { filter: invert(1); background: #000; } …

As I mentioned last week, MoneyDashboard is shutting down. They are good enough to provide a JSON export of all your previous transactions. It is full of entries like this: { "Account": "My Mastercard", "Date": "2020-02-24T00:00:00Z", "CurrentDescription": null, "OriginalDescription": "SUMUP *Pizza palace, London, W1", "Amount": -12.34, "L1Tag": "Eating Out", "L2Tag": "Pizza", "L3Tag": "" }, { "Account": "American Express", "Date":…

I quite like the new Outlook for Windows. But it has a couple of annoying bugs. One of which is, when it is maximised it doesn't let you unhide your bottom task bar. I've set up Windows so the taskbar disappears whenever my cursor isn't at the bottom of the screen. When my mouse touches the bottom, the bar appears. Lovely! But Outlook breaks this functionality - which I'm pretty sure existed back in Windows 95. Microsoft have received several complaints about this, but done nothing. Anyway,…

A few weeks ago I was moaning about there being no OpenBanking API for personal use. Thankfully, I was wrong! As pointed out by Dave a company called Nordigen was set up to provide a free Open Banking service. It was quickly bought by GoCardless who said: We believe access to open banking data should be free. We can now offer it at scale to anyone - developers, partners and Fintechs - looking to solve customer problems. And, I'm delighted to report, it works! As a solo developer you can…

Here's a quick scrap of code that works. There are lots of outdated tutorials out there for old versions of WordPress. This one is tested to be working in WordPress 6.3.2. This will pop up a confirmation dialogue when you try to publish, update, or schedule a post or page. The Code Add this to your theme's functions.php file: add_action( "admin_footer", "confirm_publish" ); function confirm_publish() { echo <<< EOT <script> var publishButton =…

WordPress allows you to set a featured image - called a "thumbnail" in the API. This gives a single image which can be used on a listing page, or shown when a post is shared on social media. The WordPress Media Library lets you set the alt text of an image. But, crucially, this alt text can be different when the image is used as a featured image. Here's how to find all your featured images which don't have alt text. One Liner Paste this into wp shell to get a list. foreach (get_posts(…
