The secret is out!

I'm the author of Magnus Protocol novel WORK YOUR FINGERS TO THE BONE. When an analyst at the UK's weirdest hedge fund discovers an artefact of great power, he exploits it for fun and profit... but success comes at a terrible price.

One of the takeaways from my brief time spent studying to be a therapist is that there are a vast number of counselling types (person-centred, psychoanalytic, CBT, Gestalt, etc, etc) and they all have roughly the same effectiveness. But, notably, they're all effective for *different people*.
An overall principle to remember is that no single intervention has a 100% efficacy rate. At the population level, nothing even comes close. So although research can suggest the most promising avenues, if something doesn't move the needle for you, that should not be cause for despair.

Lovely little write up here that I think very much gets what we were putting down!
We’ve got your reviews for ya, we’ve got your reviews!

@lunagrayhorror.bsky.social joins us at SH to think about Premee Mohamed’s entry into the Magnus Archives.

“Tie-in fiction usually means a guided tour of familiar rooms. Mohamed reconsiders the source instead.”

Good to see the Society of Authors (at least a bit) coming to their senses. AI can and should be fought at every level, especially within the creative industries.

Very excited to have worked with Sash to make a horrible British boarding school filled with horrible British classism for 13 Omens.
The immersive horror in 13 Omens is created by the Paizo team AND our friends! Get hyped for our guest authors writing zines for the game, and give them their flowers (black dahlias preferred)!

Was just wondering whether to renew my membership for next year. Guess that's answered that question. There is no "ethical" use of AI and there never will be.

Apparently I've been voted "Tumblr's favourite John", which is equal parts flattering and baffling. Or is it perhaps a curse? Impossible to say.

I've seen people call my dad a nepotism hire, and I've got to refute this - I auditioned many, many my dads before casting my dad as Jurgen Leitner, and he was simply the best fit.
Meet the narrators of FROM THE LIBRARY OF JURGEN LEITNER. The audiobook will be read by Christian Coulson, with Paul Sims returning as the voice of Jurgen Leitner.

Hey now, y'all know me - I'm a bit of a private hater, but rarely a public dunker. I take a "whatever floats your boat" attitude and with a lot of esoteric stuff I'm of the opinion that we don't know what we don't know and what is "mundane" or "scientific" is always changing. BUT.

@jonnysims.bsky.social I'm convinced this wretched thing is cursed. every time i bring it with me to read on the subway it is record breaking heat and i can feel my flesh liquify and my bones soften into a putty

PAC's look always made me imagine an episode of Flight of the Concords where he played the former third member who got kicked out years back and returned to challenge them to a fight. They're overconfident cause he was always notoriously weedy, then PAC takes off his shirt.

I'd also forgotten how gay it is, in ways that one is tempted to read as unintentional until you realise Le Carre was working for MI5/6 during the time of the Lavender Scare and it's inspired by the Cambridge 5. It knows what it's doing. (Also Smiley's marriage reads quite differently in that light)
Just finished a long-overdue rewatch of the 1979 "Tinker Tailor Soldier Spy" adaptation with Alec Guiness. Fuck me we used to have acting, didn't we?

Just read the patron preview for the next strip of @bransonreese.bsky.social's Swanboy and goddammit how can I be this hype for a fuckin webcomic? Is it 2009? That's not how its supposed to work anymore. This is embarrassing.
