If you want a weird but true fact to talk about:

Dexter Holland, lead singer of The Offspring, was instrumental in this. His doctorial thesis in molecular biology was sequencing mRNA in HIV. The paper was also heavily cited in creating the COVID-19 vaccine.

Henley & Partners’ wealth migration reports have been reported all over the world, both to prove both that there's a massive exodus of wealth from the UK and that there isn't.

Our forensic review finds the data riddled with anomalies - and in key places looks fabricated:

If you were alive in the 1980s, this is among the most wonderful & truly incredible things you have ever witnessed in your lifetime.

Dear Open Source Developer,

For reasons that are not entirely clear, I am writing to you to say that your code ought to use an api that did not exist until 5 years after you wrote it.

Talking to a friend reminded me that not everyone knows the wonders of power over Ethernet.

It works *much* better than wifi-extenders, and the kit is cheap on e-bay.

It's unlikely to give you the advertised speeds, but likely to be more than fast enough normal use.

Search for "AV600"

I've had an idea for my next book which is making it hard to concentrate on the book that I'm meant to be editing even though I know I would make absolutely no progress on the new one if I were to allow myself to concentrate on that.

Perhaps the answer is to randomly make another tool instead?

I'm guessing Simon Jenkins has never visited "Brontë Country". I grew 20 minutes walk away from Haworth, we've had wind turbines since the 90s.

They were a change, but they didn't destroy the landscape. I quite liked some of them.

I'd forgotten that I'd written this entirely true software engineering story, apparently still live on the NCR Edinburgh blog, although NCR Edinburgh itself is no more.

I think that makes more sense although, given the prevalence of speeding, what it would most likely be recording is the areas where people are available/care enough to report it rather than the areas where it is most problematic.

Although I'd like there to be some accountability for people speeding through my neighbourhood, I'm not sure an "AI" app that can produce false positives is helpful. For real false positives it is unjust. For speeders it provides a way to cast doubt. I assume speed cameras have rigorous requirements

I keep being followed by outfits where the deal seems to be "pay us money and we'll list your book on our site". 3 or 4 in the last month.

If you are about to give money to one ask yourself "when did I last go to that site for a recommendation for something to read?".

I'm guessing, never.

A friend has explicit performance goals of "using AI", and has to justify themselves when they complete tasks without it.

When I next get some work done I'm going to demand that a hammer is used for each task and require an explanation for anything done without it.

Small knife with wooden handle and cylindrical blade flattened at the end.

Small knife with wooden handle and cylindrical blade flattened at the end.

I'm meant to be doing structural edits, so of course I spent the evening making a knife out of a nail.

It's surprisingly easy to do.

I'm not very good at sharpening things, but have got it cutting slightly better than the exacto style knife it's designed to replace.

Undiscovered Voices is open for submissions.

It made a real difference for me. It was the one of the early dominoes in a chain the resulted in me finding my agent and secret writing news. Without it, I'd probably still be in the query trenches.

So, I'd definitely recommend entering if you can.

If you create something original, no. If you regurgitate someone else's code from memory, possibly (it's complicated).

If you were to switch from writing code to fiction, and download terabytes of pirated e-books to train yourself on, the violation takes place before you write a single word.

It was ok if you respected the licence the author had published it under. If the code was AGPL, then it almost certainly was not ok.

If an AI regurgitates code it was trained on, the licence is stripped along with the identity of the author and their right to control how their work is used.
