Getting lots of BIMI images using Python


Glowing computer text showing dot com dot info etc.

I've written before about the moribund BIMI specification. It's a way for brands to include a trusted logo when they send emails. It isn't much used and, apparently, is riddled with security issues. I thought it might be fun to grab all the BIMI images from the most popular websites, so I can potentially use […]

Responsible Disclosure: Content Injection flaw in Gett's Website


A basic form asking for users' credit card details.

Bit of a boring write-up, but here we go. Taxi app Gett had a content injection flaw in its search function. By searching for an HTML string, it was possible for an attacker to add links or images to a page. It was really hard to contact them - but the threat of media attention […]

Minimum Viable Tweet to Semantic SVG


The Twitter logo.

One of the problems with OEmbeds of Tweets is that they're heavy. Lots of JavaScript, tracking cookies, and other detritus. See this excellent post by Matt Hobbs looking at how to make your website faster by removing Twitter embeds and replacing them with images. Here's my attempt to turn a Tweet into a semantic SVG! […]

Three small tips for shrinking SVG images

This SVG always shows today's date


A graphic of a calendar showing the date "February 25 Sunday"

For my contact page, I wanted a generic calendar icon to let people view my diary. Calendar icons are almost always a skeuomorph of a paper calendar, but I wondered if I could make it slightly more useful by creating a dynamic icon. Here it is, an SVG calendar which always display's today's date: The […]

Super Tiny Website Logos in SVG


Rows of icons - each one has the size printed next to it.

You may not realise it, but bandwidth is expensive. It costs you time, money, and battery power whenever you download a file larger than it needs to be. That's why I've become a little bit obsessed with SVG - Scalable Vector Graphics. They're the closest thing to magic that the web has when it comes […]

Put a test-card at the start of your slides


A test card is displaying on a television screen

I do a lot of talks and presentations - sometimes in boring conference centres, sometimes in pubs, and occasionally in the middle of a field. One of the things that I've learned is the audio-visual equipment is unreliable. The colours can be off, the projection can be blocked by detritus on stage, or the screen […]

The Twitter Logo As SVG Circles


The Twitter logo drawn in circles.

Five years ago, Twitter updated its logo and demonstrated that it could be made entirely of circles. Interestingly, the official Twitter logo doesn't use circles directly. So, here is an SVG I've made which is only circles: Or, without the edges, and no transparency: And the raw code: <svg height="100" viewBox="0 0 100 100" width="100" […]
