Side projects are my favorite way to learn new skills. Some of mine from over the years (and what I learned from each) in the thread below.

@rauchg Usefulness

Software hierarchy of needs / \ → Features / \ → Performance / \ → Availability / \ → Durability / \ → Security

@Simondo65 @christianlc_ @TrungTPhan What about @halidecamera ? Does it do magic or just take photos?

The iPhone camera uses computational photography, applying software to every snap. This wild photo is an eery example: the subject tries on a wedding dress and each mirror shows her in a different pose. Why? Apple insider says it’s a “mistake” in the computational photography pipeline: ➡️ “The iPhone camera doesn’t realize it was taking a photo of a mirror, so it treated the three versions of [UK actress Tessa Coates] as different people. Coates was moving when the photo was taken, so when the shutter was pressed, many differing images were captured in that instant. Apple's algorithm stitches the photos together, choosing the best versions for saturation, contrast, detail, and lack of blur.” ⬅️

@jordienr Yosemite and Big Sur. Can’t go wrong

I'd like to go to the US next year for the first time. I've always admired the cool places on my MacBook wallpapers. Any tips or recommendations?

@degisner Nice, it looks great 👌

@JacobRuizDesign There's a set of colors that you can choose when create a new habit. Nothing fancy.

I've built a custom reordering. Two weeks of work. Was it worth it?

@blankresident What's the better alternative?

@Jon4Lakers The pastels would be cooler if the apple logo was the same hue but with saturation turned up

Time for the iPhone 15 to get some love. I like the muted blue. You?

@sarthakgh Sounds like Pinker has never heard of fruit: matter that arranges itself into food and does everything it can to be eaten.

Steven Pinker:

@DanCalle @dsiroker Good point, that makes sense

@JacobRuizDesign @dsiroker I read it differently. I believe @dsiroker refers to the resolution of the passthrough image. Wearing the headset, he looked at his actual physical phone, and the phone screen had visible pixels.

@BasicAppleGuy My first lesson that form over function can be worth it if the form is good enough.

Also Happy 25th Anniversary to the Hockey Puck Mouse!

@pmarca Do you fight?

FIGHTING At a private conference this week, I was asked what I think of Mark Zuckerberg’s recent Mixed Martial Arts (MMA) training, Elon Musk’s challenge to a cage fight, and public reports that a Zuckerberg/Musk MMA fight may well happen later this year, perhaps in the actual Roman Colosseum. I said, “I think that’s all great.” And in this post I explain why. First, while the extraordinary Dana White and his Ultimate Fighting Championship (UFC) have elevated MMA into a highly popular public sport over the last 20 years, it’s important to understand how important – how primal – MMA is in the story of our civilization. MMA is the original combat sport – it was introduced to the actual Greek Olympic Games in 648 BC (!). The Greeks called it “pankration” (παγκράτιον), but it is the same thing – a combination of boxing and wrestling. To quote Wikipedia: “In Greek mythology, the heroes Heracles and Theseus invented pankration as a result of using both wrestling and boxing in their confrontations with opponents. Theseus was said to have used pankration to defeat Cercyon of Eleusis in a wrestling match, as well as the minotaur in the labyrinth. Heracles was depicted in ancient artworks subduing the Nemean lion using pankration.” “Pankration, as practiced in historical antiquity, was an athletic event that combined techniques of both boxing and wrestling, as well as additional elements, such as the use of strikes with the legs, to create a fighting sport similar to [MMA]. Although knockouts were common, most pankration competitions were decided on the basis of submission – yielding to a submission or joint lock. Pankratiasts were highly skilled grapplers and were extremely effective in applying a variety of takedowns, chokes and joint locks.” “However, pankration was more than just an event in the athletic competitions of the ancient Greek world; it was also part of the arsenal of Greek soldiers – including the famous Spartan hoplites and Alexander the Great's Macedonian phalanx.” If the hair on the back of your neck isn’t going up as you read this… MMA isn’t just a sport, it’s the sport. And today, like then, it has not only sporting elements but also real world utility. I’ll come back to that. I was also asked whether I consider Mark and Elon to be role models to children in their embrace of fighting, and I said, enthusiastically, yes. And I further recommended to the audience that they have their children trained in MMA, as my wife and I are. Kids as young as 8 and maybe even younger are totally capable of learning both the striking and grappling dimensions of the sport. MMA teaches not just combat skills – and it does teach those – but also discipline, emotional control, respect, and a deep sense of responsibility. The message to kids is not, this is how you beat people up. The message is, this is how you protect yourself – and as important, this is how you protect your family, your friends, your community. You use these combat skills in the service of others – you never start a fight, but when someone is threatening someone you love, or even an innocent bystander, this is how you end a fight. To a lot of people, this sounds like a message out of time. Surely in the modern world, one would never need to protect oneself or one’s family with actual interpersonal physical violence? I would love for that to be the case, but unfortunately, the world is evolving in such a way where that is becoming less true every day. Many of the biggest and most important cities in the United States have decided they don’t need law enforcement, and street level violence is on the rise, as anyone in those cities with functional eyes can see. People get attacked in the street, or in carjackings and home invasions, daily, in plain sight, and little to nothing happens. It’s terrible, but it’s true. And so, yes, if there aren’t going to be police to protect you and your loved ones from real world violent assault, there is a practical need to know applied self defense. And hand-to-hand fighting – MMA – is the core self defense skill. Another benefit of MMA training, for both children and adults, is physical fitness. We all know our culture is in the grip of an obesity crisis – according to the CDC, “Obesity in the United States now affects 100.1 million (41.9%) adults and 14.7 million (19.7%) children.” This is a terrible situation that curses people to shorter and unhappier lives. President John F Kennedy saw this coming in his time (!): “We are underexercised as a nation. The remedy, in my judgment, lies in one direction. That is in developing programs for broad participation in exercise by all of our young men and women, all of our boys and girls. The sad fact is that our national sport is not playing at all, but watching. We have become more and more, not a nation of athletes but a nation of spectators. There are more important goals than winning contests — and that is to improve on a broad level the health and vitality of all our people.” We did not listen to him in the decades that followed, but we can now. MMA training is likely the best path for widespread gains in physical fitness, particularly for children. MMA training itself is both effective exercise and motivates one to improve one’s strength and endurance. And not just in the abstract, as a pointless hamster wheel process, but for a purpose – to win fights. Finally, consider the combination of physical fitness and the ability to defend one’s loves. The result is self-respect – not the self-respect of armchair therapy and wishful thinking, but real self-respect, the earned realization that one is strong and useful and of merit, and of value. Skilled fighters carry themselves differently, and this is why. In our present time, where many young people are suffering from anxiety, depression, and what can only be described as anomie – again, from the Greek, ἀνομία, “lawlessness”, a collapse in the code of expected adult behavior – what could be better than a return to earned self-respect? One more thing: Lest this be taken for some kind of gendered argument, let me say clearly that I think MMA is just as useful and relevant for young girls as it is for young boys. So yes – I think it’s great that MMA is the rising American national sport, that Mark is training so hard in it (and getting jacked), that Elon, a past martial arts aficionado in his own right, is challenging Mark to a fight, and that both Mark and Elon are top-end role models for children in our society, including my own – whether they end up fighting in the Colosseum or not! If it was good enough for Heracles and Theseus, it’s good enough for us. Fight!

@stevegraham I don’t understand what people mean when they say “there’s nothing to do in city X”. Don’t all cities have the same things to do? Restaurants, bars, parks, museums. Every city is the same.

@andrewhart Did you learn anything about: 1. What happens in you expand a window to be larger than your room? 2. What if someone walks through your window? (eg. coding in a coffee shop) 3. What if you look into a mirror with UI present?

I’ve just finished watching Apple’s visionOS sessions. Some of these concepts and the way Apple has implemented the design is mind blowing 🤯 Here are 5 examples that I loved: 1. Eye zoom. Just look at _where_ on an image you want to zoom in, and pinch your fingers apart

@ImSh4yy Beautiful. How are you color matching the background with the emoji?

Working on making it as easy as possible to filter down users based on different attributes.

@siddhartharun Would love to share some photos

Me: Let's build a photography portfolio. Also me: Let's make it a platform so others can use it.

@rsms It’s an amazing contribution. Thanks for putting so much thought into it.

I guess I should have monetized Inter (alt: I'm a bad business person. Inter will always be free and open source; just LOLing at the situation here) 😆

Big run today

@alexcornell @figma Would love to see premium fonts I don't yet know about right there in the font picker. One click to try the preview version, another click to buy the full font if I like it.

Would love to see a unique take on the font picker–anything but an alphabetical list of fonts I don't use. @figma is well-positioned to offer something new. Their existing solution is famously underpowered, but even "better" font picker plugins are still just alphabetical lists.
