Someone from a nearby boat just shared these photos of us racing in the RS800 skiff this summer! #sailing

Every lens leaves a blur signature—a hidden fingerprint in every photo. In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨ With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

The scenery at Zion National Park in Utah, USA, is truly breathtaking! #FridayFeeling #FridayMorning

Because of my spinal injury, I was thinking that I wish I could have upside down belaying glasses so that I can hold a book or phone comfortably again and...this product exists, and is really inexpensive! They're called "lazy glasses" or "crochet glasses". Now to find out how well it works for me.

Square sails clearly follow a variant of the "New Version-final-new-revision-last" naming convention

My lab will be recruiting at all levels. PhD students, postdocs, and a research engineering position (worldwide for PhD/postdoc, EU candidates only for the engineering position). If you're at SIGGRAPH, I'd love to talk to you if you are interested in any of these.

I put a massive number of changes in today's release of the new version of the #quadplay retro fantasy video game console. Available now at: morgan3d.github.io/quadplay/ The main focus of these changes was mobile: new aspect ratios, new battery saving optimizations, new exported game UI options.

I didn't realize we were trying to keep it a secret

20kts of wind makes for a lot of miles put away! I just marvel at the free energy of wind and current--I'm moving my *home* around with minimal effort, cost, and environmental impact, while sitting here making a sandwich and coffee enjoying the ride. #sailing

Worth watching presentation, also provides some background info on how ReSTIR came to be and where it is heading: "ReSTIR: Traveling the Path of Reuse" www.youtube.com/watch?v=MRg9...

My team is hiring again! We've got two jobs posted: EXPERT and SENIOR writer. In our org chart, Expert is a click above Senior and focused on craft. Senior owns big parts of the game and could eventually be promoted to a direction- or craft-focused role. lnkd.in/gpYpu3QZ lnkd.in/gppUzFmj

matklad.github.io/2025/07/16/f... convinced me to try the "font-size-adjust" feature — it's now live on redblobgames.com . I'm using it to to keep the body text and code (monospace) text matched. caniuse.com?search=font-... shows Firefox (partial) support started in 2008, Chrome in 2024.

Unusually calm Salish Sea off the WA coast #sailing

Added UI improvements ( a chain meter). Lights that spin when the boss is active and an animation for the boss door opening!! #gamedev #pixelart

Nowadays, most scientific papers must include an ethics declaration, about potential conflicts of interest among the authors. I just found this ethics declaration, in a paper written in 1729 : "I Profess, in the sincerity of my Heart, that I have not the least personal Interest

A 1966 NSF grant of $80,000 finds totally unexpected “thermophile worms” living in Yellowstone’s hot springs. The discovery sits on a shelf till 1983, before becoming key to the development of PCR genetic testing. Invest in basic research. @radiolab.bsky.social podcasts.apple.com/us/podcast/r...

I retired 5 years ago at age 67. I feel that is when my “real career” began. I have never been more engaged, productive, and fulfilled. It was incredibly liberating to decide I could switch to working for no salary: no boss to argue with and working purely on topics that inspire me. It is magical.

It’s been 3,174 days since I escaped corporate life. I was 44. My children were tiny. Now they're teenagers. Today I turn 53, and we are infinitely happier here, in our farmhouse by the ocean. No more meetings. No more commute. If I can escape, you can too (because I'm a dumbass). #Life #Art

More beautiful BC hiking in provincial island parks this weekend. Native arbutus/madrone trees that shed their orange bark are a distinctive fixture on these shores.

Too much of my boat storage is for shoes! Hiking boots, offshore boots, ankle sailing boots, reef shoes, slippers, slides, sailing sneakers, shore sneakers, hip waders, and lightweight summer sailing sneakers. And I still have nothing "nice" to wear on shore for socializing... #sailing

Come to my HANDS-ON Lab at SIGGRAPH 2025 and teleport a quantum state! Wednesday 13 August, 3:15-4:45, in the beautiful Vancouver Convention Center, West Exhibit Hall B s2025.conference-schedule.org/presentation...

This is a long shot, but someone sent me email about a performance issue with a negative lookbehind regexp in Markdeep and now I can't find the email to follow up. If that was you, please email me again :)

It was quite peaceful at this anchorage (and charming, including a tiny working commercial fishing dock). However, the names on the chart of Skull Rock, Massacre Bay, and Victim Island reflect tragically violent histories of tribal warfare among the Salish peoples in the area ~150 years ago.

At a mooring, enjoying the evening on Meridian. We've had an unexpected amount of wind lately in the Salish sea (from corresponding huge barometric pressure changes) but otherwise mild weather and mostly clear skies. #sailing

Annual reminder to self: "My single threaded code can't have race conditions!" Does it use a clock? Poll input devices? Read from files? Send network packets? Then your code is mulithreaded. You just can't see the source code for the other threads. It *can* have race conditions and deadlocks.

Casting off again...

I had a brief, very specific obsession with creating tiny mecha from LEGO. I'm all better now. This isn't a good hobby while cruising. Until next time...

On a modern mobile device HTML game, does it use less power if I issue fewer CPU instructions per frame or use fewer threads? How? Won't a browser end up keeping all cores filled with its other work? Aren't CPU cores fixed cost per cycle? Is there an indirect savings through fewer RAM operations?

I finally put Meridian's name on the hull! Now she's properly able to introduce herself. I spent the rest of the day re-provisioning, watering, recharging, and cleaning (with a few breaks for video meetings on AI and some debugging!) to prepare for the next few weeks of sailing.

Mmmm. Crispy new sails! Here's a tiny Aero 6 for racing in "Small Craft Advisory" conditions on its own tiny carbon mast. I use up a set of sails every season when seriously competing. I can't even practice now with my spine in bad shape, but am optimistically prepping for gear for next spring.

📗🚶Happy #Bloomsday - Today, we lose ourselves in the words and world of James Joyce’s Dublin. One of UCD's most celebrated graduates, Joyce completed his Bachelor of Arts in 1902. We are proud to honour the legacy of a literary pioneer and his groundbreaking novel, Ulysses.

MacBook Air M2 physical res is 2560x1664. It reports this to apps as 1470x956 @ 2x HiDPI pixel ratio. (The aspect ratio includes removing the menu bar/notch.) I don't understand the reported width. 2560 / 2 = 1280, not 1470! That's 1.74x, not 2x. I expected 1280x720 @ 2x. Help! What's happening?

Spherical harmonics are widely used in graphics. Ever wondered how to compute their derivatives? My HPG 2025 poster shows that it is basically free. It also comes with a code generator for C, C++, Python, GLSL and HLSL to compute SH with derivatives. momentsingraphics.de/HPGPoster202...

Picked up a mooring to do some work on my tender's electric motor. I've been warned that it is easy to get stuck in a marina. If the boat can sail, I try to do anything that can be done so when underway or at anchor/mooring ball. Cleaning, cooking, noncritical repairs, tender repairs...

Done with the long Torqeedo tiller upgrade to Degree, so I can sit at the front and be flat. "Just" replacing the tiller involved borrowing tools to get to some very hard to reach screws, taking everything apart twice for more lubrication, and changing storage mount on the mothership.

The Torqeedo throttle/tiller is a clever design with no direct connection to the motor! This allows the motor to be sealed against water ingress, and electrically isolates the user from the motor. It appears to work with a small magnet and a sensor on the motor side. Here's the tiller end:
