Gadget Review: X-Sense wireless interlinked smoke alarms

· 5 comments · 350 words · Viewed ~403 times


A smoke alarm with a backlit screen and RGB LED.

One of the problems with smoke alarms is that they aren't always easy to hear from a distance. If the alarm in your kitchen goes off, but you're upstairs listening to music - will you hear it? The law in Scotland has recently changed to require interlinked alarms. That means if one goes off, all of them sound the alarm. The good folk at X-Sense have sent me their SC07-W set to review. For about …

How would you avoid getting "Jobfished"?

A tangled mosaic of video calls.

I've just finished watching the amazing documentary "Jobfished". It tells the story of a group of people who were conned into working for a "fake" company. You can read the news article - it's pretty depressing stuff. In the middle of a pandemic, people were asked to work for what looked like an established media agency, for people who appeared to have a long history in the sector. The pay was…

Theatre Review: Magic Goes Wrong

Poster for Magic Goes Wrong. A magician in a top hat holds a goose.

There was a delightful end-of-term feel to this show. It was few days before the last performance and the cast were clearly having a lot of fun heckling back at the unruly audience. If you've seen any of the "Goes Wrong" shows on TV, you'll know exactly what to expect. A group of over-enthusiastic but under-equipped performers attempt the impossible and fail in a variety of stunning ways. It was …

Book Review: Information Warfare and Security by Dorothy E. Denning

· 550 words


Book cover showing a CRT monitor behind barbed wire.

I found this book while following a citation trail for my MSc. Published before the 21st Century (fuck, I'm old) it's a run-down of this new-fangled thing called Information Warfare. It covers electronic attacks, espionage, computer security and more. In the last 20 years, depressingly little has changed. If you removed the mentions of ActiveX and floppy disks, it'd still be 90% relevant. It…

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

· 550 words


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…

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 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…
