I recently went to a university hackathon, where students were trying to invent novel ways to help prevent pandemics. This was purely an academic exercise - they were not developing a fully-fledged app, nor were they creating official policies. I spent some time with one group discussing the privacy implications of what they had built. Thesis By monitoring nearby Bluetooth devices, we can…

There are many sectarian divides in computer. "Little-Endians" and "Big-Endians" wage bitter war against each other over the order of bits. Should line in text files end with \r\n or just \n? And both vi and emacs users fight betwixt themselves while ignoring the superior foe - nano. Perhaps the most contentious of these is the battle between URI and URL. Should we refer to links on the web…

I don't understand the world of academic publishing. Incredibly niche books, some barely longer than a novella, are sold for ridiculously high prices. Or, worse than that, they're not sold at all. Let me explain. A friend of mine recommended an obscure book, published a couple of years ago. The blurb made it look right up my alley, so I tried to buy it. I only read eBooks, but I couldn't find…

Problem: I have a multiline string - not a file - and I want to remove the first few lines from it and keep the rest. I found this surprisingly unintuitive. So these are notes in case I want to do it again. Feel free to suggest a better way! Example Given this input: $str = "Once upon\nA Time\nLived a big\nDragon\nCalled Cuthbert."; I want the output to be: "Dragon\nCalled Cuthbert." …

Hello fam! I've identified all of the mobile phones used in every single episode of Doctor Who! This post looks at S12 - but feel free to rummage in the archives. Spyfall - part 1 Straight out of the credits, and The Doctor is yapping away on this gorgeous retro flipper. It isn't the 2020 Moto Razr with folding screen - it's literally the original Razr V3i! Hello Moto! We haven't seen a Razr …

SETI is the Search for Extra Terrestrial Intelligence. They use massive radio-telescopes to search the sky for signs of intelligent life. But the sky is big. Where should we point the telescopes to improve our chances of detecting a signal? Rather than point at random stars, or promising looking constellations, I propose a more scientific approach: Find a planet where the length of the year…

Last month, I took myself on holiday with one aim - read as many books as possible. My wife and I tend to alternate our holidays - one relaxing break then one adventure break. Our previous trip was a 3 week road-trip through Australia, so this time I opted for an all-inclusive break in the Canaries at an adults-only hotel. I spent a week lying in the sunshine, eReader in hand, pausing only for…

The news has just broken that Google's Authenticator App can have its codes stolen by malware. I doubt Google will ever release a fix for this issue - their 2FA app hasn't been updated since September 2017. Update! 3 months after I published this post, Google updated their app For two-and-a-half years, Google hasn't touched their 2FA app's code. Perhaps it is perfect? Perhaps there are no…

(Another in a long list of posts which will turn out to be touchingly naïve!) When teaching people about safe sex, one topic bitterly divides people - whether abstinence is a suitable method. Simply refusing to engage in sexual activity will protect you from pregnancy, disease, and trauma. Abstinence is particularly promoted by religious zealots. Similarly, whenever social media is discussed, …

Bizarre geometries, based on ancient schematics, enable otherworldly…

I've been ranting about Bitly for years! The ubiquitous link shortener had an interesting "feature" - add a + to the end of the URl and you could see all the statistics for the link. How many clicks, referers, location of users. Here's a blog post I wrote about it way back in 2011. I often used this feature to explore how popular companies and scammers were: Terence Eden is on…

Written in brief entries from ‘Ambition’ to ‘Zzzzz’ Salway's confident debut novel chronicles the existential ups and downs of British 20-something Verity Bell. The alphabetically arranged mini-chapters make for an inventive and episodic narrative, as Verity muses on her career. For some reason I purchased this in 2013 and left it 7 years before reading. I wish I'd left it 70. I don't usually …
