What does it mean to run your own servers?


A pet cat typing on a computer keyboard.

I used to be a member of social media sites like Twitter, Facebook, TikTok, Flickr, etc. But I felt guilty because I didn't run my own servers. OK, I could host content with them. But I had a severely limited way of curating what I saw and how much I could customise what people saw of me. So I signed up to a cloud provider and installed Mastodon and Pixelfed. Neat! But I didn't really run that…

Book Review: Constance by Matthew FitzSimmons


Book cover for Constance. A fingerprint with an infinity symbol embedded.

Pure pulp sci-fi - and I loved every page of it. The best sci-fi, in my opinion, doesn't dwell too long on how the magic box works - but spends time exploring the consequences of opening it. The premise is great - cloning is real and you can back up your brain. When you die, your brain is downloaded to a clone. It's a brilliant exploration of human rights. Are clones humans? Are they property? …

Book Review: Ira Aldridge - The African Roscius by Bernth Lindfors


An African American man in a 19th Centrury portrait.

Ira Aldridge -- a black New Yorker -- was one of nineteenth-century Europe's greatest actors. By the time he began touring in Europe he was principally a Shakespearean actor, playing such classic characters as Shylock, Macbeth, Richard III, and King Lear. Although his frequent public appearances made him the most visible black man in the world by mid-nineteenth century, today Aldridge tends to…

Where are the U2F Rings?


Photo of an NFC ring, taken by Rain Ashford.

The FIDO specification defines a form of Universal 2nd Factor (U2F) when users log in to a system. Rather than relying on one-time codes sent via SMS, or displayed on a phone screen, these are physical hardware tokens which are used to supplement passwords. When used with websites, this technology is also known as WebAuthn. I use a USB thumb-drive sized hardware token and they're nifty - but a…

What's the lowest positive integer for which there are no Google search results?


Google search page showing no results.

I found this rather humorous Tweet in which a computer issued a cheque for £2,324,252,080,110: Gareth Hughes@gh230277Thank you for our compensation payment @Northpowergrid for the several days we were without power following #stormarwen Before I bank the cheque however, are you 100% certain you can afford this? #trillionpounds pic.x.com/z5MNc2Nxl1❤️ 48,014💬 2,051🔁 011:52 - Sat 12 February 2022 I…

The existential terror of LinkedIn


People on linkedin wanking themselves dry over how clever they are.

Several years ago, I applied for my dream job. Not quite ice-cream tester on the International Space Station, but pretty close. I was astounded to get a first interview, and crushed to flame out at the second round. That's the way it goes sometimes. Better to have tried and failed than never to have tried at all. In the past, that would have been the end of it. I'd have moved on with my life and …

Book Review: The Kaiju Preservation Society by John Scalzi


Book cover featuring a gigantic monster.

Oh! But this is ridiculously fantastic fun. An unemployed sci-fi geek escapes the pandemic by going all David Attenborough with Godzilla. Yes, it is an exercise in nerdy wish fulfilment. But who among us wouldn't have rather spent the last two years being chased by giant scary monsters rather than cowering away from a microscopic virus? It a joyful piece of bubble-gum sci-fi. It plays well…

Book Review: Startide Rising (Uplift Trilogy 2)


Humans and cyborg dolphins swimming in an alien sea.

Dolphins in spaaaaaaaace! This is the sequel to David Brin's "Sundiver" - and the 2nd part of the Uplift series. And - BAM! - it goes straight into the action. Very little needless exposition - just spaceships running away from an Extra-Terrestrial menace, crash-landing, and having to escape. All good sci-fi fun. Especially with a crew of cyborg dolphins, a few telepathic humans, and one…

Book Review: Die With Zero


Die With Zero book cover.

Spoiler Alert! We're all going to die. I'm the sort of person who buys a fancy jar of something delicious - and then I save it for a special occasion. Yet, somehow, those special occasions never seem special enough. And so the jar sits at the back of the cupboard waiting for a train that's never going to come. How many of you do the same? This book attempts to change that. Why do you spend your …

Reboot and launch an Android app via ADB


Android logo.

I'm using an old Android phone as a webcam. The camera lens is great, the DroidCam software is nifty, but the Android OS behind it is old and dying. My phone often needs rebooting. Which means that the app also needs restarting. The phone's screen faces away from me, so I can't interact with it. This is a quick guide (mostly notes to myself) about rebooting and starting an app from the command…
