Probably the ultimate Turing test.

x86 `bsr` opcode gives an undefined* result for input value 0. Windows intrinsic _BitScanReverse64()'s returns 0 for input 0 to handle this case. Use it in a ternary statement to generate branchless code. Hope this helps.

Tron: Ares is a very colorful movie in which many things happen. But it misses a big part of what made the original "Tron" work. Since no one asked, let's talk a bit about cyberpunk, video games, and religious allegory.

[Me: buys various plumbing and cleaning chemicals at hardware store] Cashier (joking): Heh, are you building a bomb? Correct answer: "Ha ha no, these are all for different rooms." My answer (distracted): "What? No, combining this would just make chlorine gas; you'd need an oxidizer for detonation."

In 426BC, Athenian politician Cleon prosecuted the comedian Aristophanes for making fun of him in front of foreigners. In response, Aristophanes produced The Knights, a play comprised entirely of slander against Cleon. It won Best Comedy in 424BC. en.wikipedia.org/wiki/The_Kni...

Just noticed I misspelled “prefetching” as “prekvetching” in a dozen comments, and tbh that might be a more honest description of how I perf

Tim Sweeney is catching heat for saying games perform poorly when their devs leave optimization til too late, and … is this not obviously true? You have to plan for the hardware you’ll ship on the same way you need to measure a room before putting furniture in it. clawsomegamer.com/tim-sweeney-...

What the heck is going on here? Walter White?! I just asked it whether I should use Fantastik or Windex in my bathroom, and now it’s dropping hints about cooking meth.

Copilot is alarmingly enthusiastic about this topic.

Well, that Strange New Worlds was extremely TOS in the best way. Maximum Roddenberry. Set phasers to allegory.

A letter to the editor of a Burbank newspaper is very concerned that letting people build low-rise apartment buildings along a major bus route would replacement single-family houses with rental units, making the neighborhood less affordable. The single-family houses:

Pet peeve: when people hit enter on every pause in their thinking so a single sentence becomes a dozen messages stretched out in time over minutes but each one needing me to look if they're finally done and waiting for me to reply. I call this "Shatnerspacing"

This, and: the most impactful writing work in games is in barks, lore, environmental narrative, diegetic text. Games are not screenplays! The player experiences the story by inhabiting it.

Years later, still the best assert message I've written.

A nonprofit wants to build 60 subsidized, low-income apartments near me. At a city meeting, locals objected to this project; they said it would add traffic to an already very busy street. So, the next Monday, I went there to record rush hour traffic.

They say that investing in public transportation pays dividends for years. In the case of the San Francisco BART, that dividend is 5% per year.

Best health decision I ever made was to put my exercise bike in front of my PS5 and set a rule that I’m always pedaling if I’m playing. I have just discovered that Blue Prince is included in PlayStation Plus. So, I guess that’s my cardio sorted for the rest of the month.

Working with the team Ted built has been one of the greatest opportunities of my career. Having built a studio from three guys in a room to the top of AAA, Ted Price has won at game development, and imo changed the whole industry for the better.

Ted retires today. There will never be enough words or time to express my gratitude for his contribution to games, his selfless leadership, and his impact on my life. At the very least, I got to share a bit of that on Insomniac Live last week...

The conference is over, put your badges away! #gdc #gdc25

#TacticalBreachWizards is such a masterclass in how theme, story, and gameplay are more than the sum of their parts. eg, level designs convey character beats & the character’s personality inspires the level design.

Getting into the Tactical Breach Wizards talk was surprisingly straightforward. I didn’t even have to explode the door. Anyway, interesting design pillar: “let player should enjoy the game in their own way; they shouldn’t feel stuck.” Also 💛 the shoutout here. #gdc #gdc25

There is apparently some kind of vampire aficionado convention happening in the hotel next to our office, and when I walked near it a few people assumed I was part of the con and tried to direct me inside. Dearest reader, I am not even in costume.

My tips for #GDC speakers: • Rehearse, rehearse, rehearse. Run through your talk every day between now and stage time. The more you practice, the more comfortable you'll be. Getting it right will feel like a habit. Record yourself so you can feel the pacing.

@judith-levine.bsky.social Hello - I recently read your article in The Guardian and have been thinking about it a lot. How literally should it be read? www.theguardian.com/commentisfre...

If better dialog and happier designers turns out to be my lasting legacy in the game industry, I think I'm fine with that.
