Book: The Man from the Future: The Visionary Life of John von Neumann

John von Neumann, a name synonymous with the birth of modern computing, artificial intelligence, and game theory, has left a mark on the fabric of technology and science. The biography, “The Man from the Future,” penned by Ananyo Bhattacharya, offers a glance into the life of one of the most brilliant minds of the 20th century.

  • The landscape of mathematical thought in early 20th century: The book starts by recapping advancements in mathematics and physics in the early 20th century by famous scientists like Godel and Schrodinger
  • Introduction to John von Neumann’s Life: Born Neumann János Lajos, he was a child prodigy with an exceptional mind, evident from his early inclination towards reading over traditional child’s play.
  • Transition to America: Migrating in 1930, von Neumann anticipated the global shift towards war, studying the mathematics of ballistics and explosions.
  • Contribution to the Atomic Bomb: His role was pivotal in determining the explosive arrangement for the “Fat Man” nuclear device.
  • Pioneering Artificial Intelligence: His work laid the foundational stones for the emergence of artificial intelligence and neuroscience.
  • Influence on Modern Computing: Von Neumann’s insights into computing architecture continue to influence modern digital computers and the conceptualization of the internet and cybernetics.
  • Game theory and other legacy contributions

Human side

Despite being accused of not always being human, Von Neumann displayed an array of human quirks:

  • He played German marching tunes loudly in his office, much to the dismay of neighbors like Einstein and Gödel
  • ” ‘Johnny preferred admirals to generals, because the generals drank iced water for lunch, while the admirals when ashore drank liquor,’”
  • (About Zero-Sum games): What von Neumann disliked most about Nash’s approach, though, was the axioms upon which it was built. The idea that people might not work together for mutual benefit was anathema to him. He was central European to the core, his intellectual outlook shaped by a milieu where ideas were debated and shaped over coffee and wine.
  • He loved to drive FAST but was a bad driver: The couple would buy a new car every year, usually because von Neumann had totalled the previous one. His vehicle of choice was a Cadillac, ‘because’, he explained whenever anyone asked, ‘no one would sell me a tank’. Miraculously, he escaped largely unscathed from these smash-ups, often returning with the unlikeliest of explanations. ‘I was proceeding down the road,’ begins one fabulous excuse. ‘The trees on the right were passing me in orderly fashion at 60 miles an hour. Suddenly one of them stepped in my path. Boom!’

Apart from Neumann himself, the book shares quite a few funny anecdotes about other researchers, too.

Multidisciplinary impact

From the development of the atomic bomb to the foundational theories behind modern computing and artificial intelligence, von Neumann’s work has had a profound impact on numerous fields:

  • Nuclear Physics and the Manhattan Project: His strategic involvement in the Manhattan Project and his subsequent work on thermonuclear weapons underscored von Neumann’s pivotal role in the development of nuclear technology. His contributions to the design and understanding of nuclear fission and fusion have had lasting implications for both military strategy and energy production.
  • Neural Networks and the Concept of Artificial Intelligence: By drawing parallels between the human brain and computing machines, von Neumann laid the groundwork for the field of artificial intelligence. His vision of machines that could mimic human thinking patterns anticipated future discussions and developments in AI research.
  • Economic Theory: Through his work in game theory, von Neumann revolutionized economic theory, providing a mathematical framework to understand and predict the behavior of economic agents in competitive situations. This has had a profound influence on economics, political science, and psychology.
  • The EDVAC Report: Von Neumann’s report on the EDVAC outlined the architecture for stored-program computers, setting the stage for future technological advancements.
  • Monte Carlo Method: Innovating in the realm of computational mathematics, von Neumann introduced the Monte Carlo method, a cornerstone for solving complex problems through random sampling. This technique has become essential in fields as diverse as finance, physics, and engineering, showcasing his ability to transcend disciplinary boundaries with his insights.
  • Quantum Mechanics and Game Theory: His contributions went beyond practical inventions, influencing theoretical realms such as quantum mechanics and the development of game theory.

John von Neumann’s biography offers a window into the life of a man whose intellect and contributions have shaped the modern world in innumerable ways. From his early life to his passing, von Neumann’s journey is a testament to the power of human curiosity, intellect, and the capacity to influence future generations.

My highlights

  • ‘Von Neumann would carry on a conversation with my three-year-old son, and the two of them would talk as equals, and I sometimes wondered if he used the same principle when he talked to the rest of us.’
  • von Neumann felt that János – his real name – sounded altogether too foreign in his new home.
  • von Neumann enjoyed annoying distinguished neighbours such as Albert Einstein and Kurt Gödel by playing German marching tunes at top volume on his office gramophone.
  • He moved to America in 1930 and, realizing early on that war was looming, studied the mathematics of ballistics and explosions.
  • it was von Neumann who determined the arrangement of explosives that would be required to detonate the more powerful ‘Fat Man’ device by compressing its plutonium core.
  • Later, his musings on the parallels between the workings of brains and computers helped to trigger the birth of artificial intelligence and influenced the development of neuroscience.
  • Neumann János Lajos (in English, John Louis Neumann – the surname comes first in Hungarian)
  • Puzzled that young Jancsi only ever played scales on the cello, his family investigated to find that the five-year-old had taken to propping up books on his music stand so he could read while ‘practising’.
  • Displaying a sensitivity towards the feelings of others that is not always found in those with remarkable brains, von Neumann took care not to be overbearing yet could not but help stand apart.
  • ‘God made the natural numbers; all else is the work of man,’ growled Leopold Kronecker, a contemporary grandee of German mathematics who found Cantor’s juggling with infinities suspicious and distasteful. He called Cantor a ‘charlatan’ and ‘corrupter of youth’ and squashed his hopes of moving from Halle University to a chair at the much more prestigious University of Berlin.
  • The core ideas in Heisenberg’s revolutionary paper were assembled during a two-week stay in June 1925 at Heligoland, a sparsely inhabited rock shaped like a wizard’s hat that lies some 30 miles north of the German coast.
  • that the two did not commute either. Multiplying position by momentum or, conversely, momentum by position gives slightly different results. The difference (less than a trillionth of a trillionth of a billionth of 1 joule-second)
  • Pondering the physical meaning of noncommutativity led Heisenberg in 1927 to an extraordinary new law of nature, which stated that the position and momentum of a particle cannot both ever have exact values at the same time.
  • based on the German word eigen, meaning ‘characteristic’ or ‘inherent’.
  • Armed with his delta function, Dirac was able to show wave and matrix mechanics might after all be two sides of the same coin. The delta function acts as a sort of salami slicer, cutting up the wave function into manageable, ultra-thin slivers in space.
  • ‘This boundary,’ he concluded, ‘can be pushed arbitrarily far into the interior of the body of the actual observer.’ And that was true, said von Neumann, right up until the act of perception (whatever that was). The ‘boundary’ that he describes is now known as the ‘Heisenberg cut’. More rarely (but perhaps more fairly) it is called the Heisenberg-von Neumann cut.
  • Three years after the publication of von Neumann’s book, Schrödinger discussed with Einstein the weaknesses in what would become known as the Copenhagen interpretation of quantum mechanics. Inspired by their frenzied exchange of letters, Schrödinger posed the most famous thought experiment of all time to highlight the absurdity of applying quantum mechanics willy-nilly to everyday objects.
  • Otto Frisch, who first explained the physics behind their results, a type of nuclear reaction that Frisch later named ‘fission’. Meitner,
  • Von Neumann resigned from the NDRC in September 1942 to join the Navy. ‘Johnny preferred admirals to generals, because the generals drank iced water for lunch, while the admirals when ashore drank liquor,’ said Leslie Simon, a director of the BRL. More likely, von Neumann thought the problems the Navy needed him for were more pressing than those of the NDRC.
  • his work at ‘Site Y’ would not be mentioned – unsurprisingly as so much of it was secret. Instead, when he was awarded the Medal for Merit by President Truman the citation was for his research on the ‘effective use of high explosives, which has resulted in the discovery of a new ordnance principle for offensive action, and which has already been proved to increase the efficiency of air power in the atomic bomb attacks upon Japan’.
  • The first layer of this giant apocalyptic onion was 11.5 cm of aluminium called the ‘pusher’, designed to enhance compression of the plutonium core by preventing a steep drop in pressure behind the shock-wave front. Next came a 120 kg shell of natural uranium (unrefined uranium, composed mostly of the non-fissile isotope uranium-238, was in plentiful supply) – the ‘tamper’. Its purpose was to delay the expansion of the plutonium core inside, so allowing the chain reaction to proceed for a fraction of a second longer after detonation. For every 10 nanoseconds the tamper held the core together, another generation of neutrons would blossom inside the fissioning plutonium, violently converting more mass to energy. A hole drilled through this tamper allowed the plutonium pit, an apple-sized 6.2 kg ball 9 cm in diameter, to be inserted into the device at the very end. This was a sub-critical mass, to be squeezed into criticality by the shock wave. The plutonium pit was itself composed of two hemispheres with a 2.5 cm cavity in the middle to hold ‘urchin’, the initiator, made of polonium and beryllium and designed to trigger a chain reaction in the plutonium. Half the size of a golf ball, the initiator was a tour de force of precision engineering. The polonium isotope the scientists used, Po-210, releases alpha particles that, on striking beryllium, liberate a burst of neutrons. The two elements can be kept apart easily enough: alpha particles cannot penetrate more than a few hundredths of a millimetre into metal. But the initiator had to be carefully designed so that beryllium and polonium also mixed thoroughly the moment the plutonium core was compressed. This was achieved by plating a nugget of beryllium with nickel and gold and depositing polonium on the surface. The nugget was itself enclosed by a shell of nickel and gold-plated beryllium, which had fine grooves cut into its inside surface to hold more polonium. The implosion shock wave would crush the initiator, instantly dispersing the polonium sandwiched between the inner and outer spheres of beryllium.
  • Spurred by von Neumann and the numerous computers springing up in the wake of his project, the company rapidly changed course, producing digital stored-program machines in the EDVAC mould. The IBM 701 was, says Bigelow, ‘a carbon copy of our machine’.82 By the 1960s, IBM manufactured about 70 per cent of the world’s electronic computers. ‘Probably’, Teller told his biographers, ‘the IBM company owes half its money to Johnny von Neumann.’83
  • In reflective mood in 1955, he noted that the ‘over-all capacity’ of computers had ‘nearly doubled every year’ since 1945 and often implied in conversation that he expected that trend to continue. His observations prefigure ‘Moore’s law’, named after Intel’s cofounder Gordon Moore, who predicted in 1965 that the number of components on an integrated circuit would double every year.
  • ‘Von Neumann cleared the cobwebs from our minds as nobody else could have done,’ wrote Bigelow long afterwards. ‘A tidal wave of computational power was about to break and inundate everything in science and much elsewhere, and things would never be the same.’
  • ‘You mean, the theory of games like chess?’ ‘No, no,’ he said. ‘Chess is not a game. Chess is a well-defined form of computation. You may not be able to work out the answers, but in theory there must be a solution, a right procedure in any position. Now real games,’ he said, ‘are not like that at all. Real life is not like that. Real life consists of bluffing, of little tactics of deception, of asking yourself what is the other man going to think I mean to do. And that is what games are about in my theory.4 Von Neumann was not the first to analyse
  • Von Neumann could not get any further with multi-player games, so he switched to thinking about a situation with just two opponents whose individual payouts sum to zero. ‘It is not enough to succeed. Others must fail,’ Iris Murdoch once wrote. Von Neumann coined the term ‘zero-sum’ to describe such games of total conflict, in which one person’s loss is the other’s gain. One indication of the influence of game theory is that ‘zero-sum’ has now passed into the vernacular.
  • But the idea that the bomb be detonated within a vessel, later codenamed ‘Jumbo’, stuck, and a 14-inch-thick steel cylinder weighing around 200 tons was built for the job. It was never used, one concern being that if the bomb did actually produce an explosion even a fraction of the expected size, Jumbo would instantly be transformed into 200 tons of radioactive shrapnel. Groves, fearing Congress would regard the $12 million Jumbo to be a white elephant, ordered it destroyed. Several 500 pound demolition bombs could only blow the ends off the vessel, however. Jumbo’s rusting hulk still stands in the New Mexico desert today.
  • The scientists wagered on the explosive yield of the bomb. Some still thought zero was the most likely figure. Downplaying the chance of success, Oppenheimer chose 300 tons TNT equivalent. Teller, an optimist where bombs were concerned, picked 45,000 tons and passed around a bottle of suntan lotion. The sight of scientists slapping on sunscreen in the pitch dark perturbed some of the assembled VIPs.
  • Fuchs and von Neumann attended a conference at Los Alamos on thermonuclear weapons. Their jointly authored patent is somewhat euphemistically entitled Improvements in Method and Means for Utilizing Nuclear Energy. In fact, the patent contains plans for a thermonuclear weapon.
  • The Fuchs-von Neumann patent is still classified in the United States but its contents are now known. Starting in the 1990s, post-Soviet Russia began declassifying and publishing historical documents relating to their bomb project – including a host of Manhattan Project papers obtained through espionage. Fuchs claimed some credit for the discovery of radiation implosion in 1950 while serving a fourteen-year prison sentence for breaking the Official Secrets Act. Von Neumann, on the other hand, never spoke about it. He was probably not keen to draw attention to his top-secret work with a self-confessed Soviet spy.
  • Von Neumann’s First Draft of a Report on the EDVAC is a curious document. He mentions electronic components mostly to explain why he will not be discussing them: his aim is to describe a computer system without getting bogged down in the specifics of engineering. ‘In order to avoid this we will base our considerations on a hypothetical element, which functions essentially like a vacuum tube,’ he says.41 His ‘hypothetical element’ is an idealized neuron, shorn of its physiological complexities. This seems odd today, but von Neumann, Turing, Norbert Wiener and other thinkers who contributed to the foundations of the field that became known as ‘artificial intelligence’ did think about computers as ‘electronic brains’. Today using ‘brain’ or ‘neuron’ in the context of computers seems laughably naive. Yet we accept the similarly anthropomorphic use of ‘memory’ to mean ‘storage’ without blinking an eye.
  • Ulam presented his idea to von Neumann during his next visit to Los Alamos. Von Neumann was preparing to leave, so Ulam hopped into the government car taking him to the train station, and they fleshed out the details together during the long journey. In March 1947, von Neumann sent an eleven-page plan for running Monte Carlo bomb simulations on an electronic computer to Robert Richtmyer, head of the Los Alamos theoretical division. Computers now run Monte Carlo simulations thousands of times a day, and applications range from optimizing stock portfolios to testing the properties of new materials.
  • Klári’s (von Neumann’s wife) 800-command program that ran in April in Aberdeen was used to adjust the composition of atom bombs. Within that program is a ‘closed subroutine’ – a type of loop that is executed whenever it is referenced from the main body of the program. The invention of the closed subroutine is generally credited to computer scientist David Wheeler, but Klári’s code made use of one at least a year earlier, to generate random numbers by von Neumann’s ‘method of middle-squares’. Debate still rages in some quarters over whether the ENIAC in its new guise really constituted a true ‘stored-program’ computer. There can be little doubt, however, that Klári’s Monte Carlo code is the first truly useful, complex modern program ever to have been executed.
  • von Neumann’s machine-gun delivery accompanied by his usual habit of wiping the blackboard clean before anyone could catch up with him probably explained why his thoughts did not immediately reach a wider audience.
  • ‘If these books are unearthed sometime a few hundred years hence, people will not believe that they were written in our time,’ von Neumann confided to a friend in 1947, referring
  • Despite the generally frosty reception, ‘A Model of General Economic Equilibrium’ sparked a revolution. Mathematicians, inspired by von Neumann’s achievement, poured into economics and began applying fresh methods to the dismal science. By the 1950s, the subject was transformed. Fixed-point theorems were used to prove key results in economics – including in von Neumann’s own game theory by a young upstart called John Nash. A half-dozen Nobel laureates are reckoned to have been influenced by the work.26 Among them were Kenneth Arrow and Gérard Debreu, who were awarded the prize (in 1972 and 1983 respectively) for their work on the theory of general equilibrium, which models the workings of a free-market economy. A half-century after von Neumann’s Princeton seminar, the historian Roy Weintraub described his paper as ‘the single most important article in mathematical economics’.27
  • A year before the translated paper appeared, he produced Theory of Games and Economic Behavior, the book that would forever change the social sciences and profoundly influence economic and political decision-making from the 1950s to the present day.
  • Morgenstern was an oddball. Tall and imperious, he rode through Princeton on horseback, immaculately attired in a business suit. He was born on 24 January 1902 in Görlitz, then in the Prussian province of Silesia, but grew up in Austria. His mother was the illegitimate daughter of German Emperor Frederick III and after he moved to the United States, Morgenstern proudly kept a portrait of his grandfather, the Kaiser, hanging in his home
  • Bohr was drawing a parallel between the perturbations caused by the interactions of economic actors and the collapse of the wave function. Von Neumann’s seemingly divergent interests had a funny habit of colliding with each other in interesting ways.
  • John Maynard Keynes, whose thinking shaped government policy the world over for much of the twentieth century, was ‘one of the biggest charlatans who has ever appeared on the economic scene’, said Morgenstern. ‘And everybody is on their belly before him.’
  • McDonald describes two grocers being undercut by a supermarket in game-theoretic terms: ‘The two grocers make a coalition against the consumer; they play a two-man game with each other which results in taking more money from the consumer. Along comes the supermarket offering prizes or payments to the consumer in the form of lower prices (based on higher output and lower costs). Supermarket and consumer make a coalition … against the grocer coalition. The supermarket receives payments in profits (from larger volume at lower prices for each consumer); the consumer receives payments in savings. But the game is not over when the first grocer coalition retires from the field. If the supermarket has other competitors, as it usually does, the consumer can maintain a strong position by threatening coalitions with those competitors. But if the supermarket and its competitors now combine, they could make additional gains through higher prices for a while at the consumer’s expense. The situation with which the game began would then be restored, to be upset, perhaps, by another newcomer.’
  • Collbohm caught the first plane he could – a B-25 bomber – to company headquarters in Santa Monica, where he rounded up Douglas and a few other company executives. The deal was done quickly. Arnold told the group he had $10 million of unspent funds from his wartime research budget which he was willing to give Douglas Aircraft to fund the new outfit. Douglas agreed to find space for the organization at their Santa Monica offices. Arthur Raymond, Douglas Aircraft’s chief engineer, suggested the name: RAND for ‘Research ANd Development’. Collbohm volunteered to lead it until a more suitable candidate could be found. His ‘temporary’ appointment as director would last twenty years.
  • The think tank’s very first report was released on 2 May 1946. Preliminary Design of an Experimental World-Circling Spaceship concluded that ‘modern technology has advanced to a point where it now appears feasible to undertake the design of a satellite vehicle’. Such a craft would be ‘one of the most potent scientific tools of the Twentieth Century’ and the achievement ‘would inflame the imagination of mankind, and would probably produce repercussions in the world comparable to the explosion of the atomic bomb’.
  • Early computing work on the ‘Super’ required random numbers for Monte Carlo simulations, so RAND engineers built an electronic device to generate them. This was compiled into a surprise best-seller entitled A Million Random Digits and 100,000 Normal Deviates.
  • Let each boy propose to his best girl. Let each girl with several proposals reject all but her favorite, but defer acceptance until she is sure no one better will come her way. The rejected boys then propose to their next-best choices, and so on, until there are no girls with more than one suitor. Marry. The result is stable, since the extramarital liaisons that were previously rejected will be disliked by the girl partners, while all others will be disliked by the boy partners.31
  • The Nash portrayed in Sylvia Nasar’s biography, upon which the film is nominally based, is a petulant bully who advises his mistress of four years to give up their son for adoption. The physically imposing Nash later threw his future wife ‘to the ground and placed his foot on her neck’ during a maths department picnic.33
  • Nash implied that his own blood lines were pretty good.’
  • What von Neumann disliked most about Nash’s approach, though, was the axioms upon which it was built. The idea that people might not work together for mutual benefit was anathema to him. He was central European to the core, his intellectual outlook shaped by a milieu where ideas were debated and shaped over coffee and wine.
  • Some futurologists are now speculating that a superhuman artificial intelligence could transform human society beyond all recognition. That possibility has become known as the technological ‘singularity’ – and that term was first used by someone who had foreseen the possibility decades earlier: John von Neumann.99
  • The couple would buy a new car every year, usually because von Neumann had totalled the previous one. His vehicle of choice was a Cadillac, ‘because’, he explained whenever anyone asked, ‘no one would sell me a tank’. Miraculously, he escaped largely unscathed from these smash-ups, often returning with the unlikeliest of explanations. ‘I was proceeding down the road,’ begins one fabulous excuse. ‘The trees on the right were passing me in orderly fashion at 60 miles an hour. Suddenly one of them stepped in my path. Boom!’
  • ‘For progress there is no cure.

[Deliberate 107] Is air travel really that annoying? My best tips.

I’m Artur, and I am an over-optimizer.
(Hi Artur 👋)

Howdy to Deliberate Internet – my newsletter combining nuanced perspectives on Remote Work, Technology, Psychology, and other latest obsessions.

I’m just coming back from a 3-day work trip to Taiwan. I spent almost as much time on the planes as I did enjoying Taiwan, so I was thinking about the in-flight experience.

Tech people spend way too much time thinking about the in-flight experience

Modern air travel is a miracle of engineering, logistics, and the democratizing force of mass manufacturing. We can get people to the other side of the globe in about 16 hours, or the other side of the continent in 4. The experience is objectively pretty awesome as well! You get to chill for a few hours, watching your own personal TV while they serve you food prepared thousands of meters above the ground.

And yet, we manage to complain: Babies are crying, this dude is reclining his seat, and they ran out of Diet Coke. Oh, the legroom.

I spent much more time thinking about making my in-flight experience a little more pleasant than I actually do sitting on the plane. I will spend hours picking my flights, downloading shows to watch, or making sure my equipment is charged, only to sleep through the whole affair.

It seems that for people who are used to solving problems, the air cabin is like catnip: full of optimizations and inefficiencies and ripe for solutions, process improvements, or good management. How is it that a 5-hour drive seems like just a thing to get through, but a 5-hour flight is a battle you have to prepare yourself for as the future of your kingdom depends on it?

I suspect it’s all about feeling powerless:

  • You cannot “just stop” whenever you feel like it
  • The entire system hinges on you complying with random demands of authority
  • All you have to do is wait

To be a good airline passenger, you have to be good at going with the flow. Not my strong suit. But to my credit, I don’t think I’m alone!

Tech people’s little acts of rebellion

The first noise-canceling headphones were designed by Dr. Amal Bose, who invented the canceling wave while sitting in an airplane. Apple Vision Pro seems like an evolution of that concept: you get your own personal bubble to sit in and enjoy the screens you choose.
It seems like the tech crowd is inventing conveniences as little acts of rebellion against this tyranny.

I also wonder how engineers dealt with long sea voyages. Did they try to optimize every single aspect of it too?

Air travel tips

While we’re on the topic of air travel, here are my assorted tips:

  • The most luxurious thing you can do in the airport is have a shower. Most lounges have this option. Check on loungebuddy.com
  • Buy a good sleep mask and earplugs. Travel pillows, on the other hand, are overrated, bulky, and useless
  • During the security check, when you are taking out your laptop, batteries and cosmetics, put your bag in first to the X-ray machine, and then the tray with your loose items. On the other side you will have bag first to put this stuff in.
  • Put an airtag in your luggage. You will know much sooner than the airline if something is not ok (like it being on the other continent)
  • You can buy lounge access through programs like PriorityPass, DragonPass, and partnerships with your credit card (or Revolut). It’s about $30 per entry.
  • If you are traveling a lot, look into points. But it only makes sense if you have at least 2 intercontinental flights per year. I used to do Aegean Miles& Bonus
  • Most planes get pretty cold. Sweatpants and a hoodie are the only reasonable choice as attire
  • The aisle seat armrest seems fixed, but there is a button under the hinge to unlock it, and then you can raise it. Then you can walk out without raising the tray table if you have stuff on it.
  • Most planes have power outlets now. Act accordingly.
  • Yes, there is plenty of free booze and coffee on long-haul flights, but both disrupt your sleep and contribute to jetlag.
  • Bring a set of wired headphones. The ones you get on a plane are terrible.
  • The biggest-bang-for-the-buck upgrade is Premium Economy, but few routes have it. Check before buying flights
  • It’s always worth having Tisuses, Paracetamol, and Melatonin, just in case.

Any other recommendations?

A thing I wrote

As I mentioned, I’m now returning from Taiwan after attending WordCamp Asia. It was a unique opportunity to interact with a community I don’t usually get to meet.

Also a fantastic excuse to visit rural Taiwan, drink some proper tea, enjoy the views and hike a bit! I visited an old mining town of Jiufen that the internet claims to be an inspiration for “Spirited Away”:

Hiking Jiufen to Ruifang via Liulang Road

Hiking Jiufen to Ruifang via Liulang Road

Jiufen is a charming old mining village on the coast of Taiwan, about 30 km away from Taipei.

It’s a very popular day-trip destination. Most people arrive by bus, but I decided to add a little hike.

Jiufen, aka “Real-life spirited away”

Jiufen is considered an inspiration for “Spirited Away”, despite Hayao Miyazaki claiming he was inspired by multiple places.

You can see a list of similarities in this post.

The most Iconic place is the A-Mai teahouse adorned with lanterns that have to look splendid when it’s dark.

I agree with this post claiming that it’s best to stay in Jiufen overnight to enjoy the lanterns in the dark.

Unfortunately, I had to get back to the airport.

Getting to Jiufen

Most people take 1065 bus from Songshan station or a train to Ruifang and a taxi from there.

I decided to limit transit time in favor of spending time outside.

I took an Uber from the Taipei 101 area for about 1100 NTD. It took 50 minutes.

Hike to Ruifang

I was studying Google Maps and pieces together a trail that should work but is not well advertised (hence this post).

It was a great idea to take this route BACK to Ruifang, as it becomes quite steep at places.

You start just by continuing the Old Jiufen road. When you pass all the stalls, you continue on the Quingbian road until you see a trail marker.

The first part of the trail is Liulang road – road made for the mining railway to transport the ore.

From what Ive pieced together, the railway was never completed because it becomes too steep close to Ruifang. Now it’s a footpath that ends with a series of steps to the bamboo forest.

Once you get to the forest, you can go on the main road.

You have to walk a few hundred meters on the road shoulder.

Once the road climbs to the viaduct over railway, go on the left side to find a footpath and pedestrian tunnel under tracks. It apparently doubles as a scooter parking.

When you cross the tracks, you can get to the river, where you can enjoy views of mountains, birds and temples.

Follow the river to Ruifang.

[Deliberate 106] VR, Revisited

Howdy to Deliberate Internet – my newsletter combining nuanced perspectives on Remote Work, Technology, Psychology, and other latest obsessions.

Recently, I’ve rented Oculus Quest 3 – the newest version of VR goggles from Meta/Facebook. I took them through the paces, and the experience was much better than 2 years ago, when I rented Quest 2.

I know Apple Vision Pro gets a lot of the spotlight now, but I’m really interested in 2 use cases:

  1. I want to simulate a private office and block out distractions. My wife keeps mocking me that I have to turn every place into a workplace, and Metaverse is no different.
  2. I want a really good cardio workout that gets me excited and doesn’t feel like a chore.

According to people as deranged as me, the productivity use case is lacking. From Ben Thompson:

The Productivity Disappointment

visionOS suffers from a similar combination of shortcomings. First off, the user interface is exceptionally difficult to manage once you have multiple windows on the screen, particularly when windows are arranged on the z-axis (i.e. nearer or closer to you in 3-D space); one gets the sense that the usability of iOS-based operating systems are inversely correlated to their screen size. Second, while the eye tracking is an incredible feat of engineering, it is not nearly as precise as it needs to be for productive window management.

The biggest limitation, though, is hardware: the Vision Pro field of view is very narrow, in a way I didn’t fully appreciate while only using one app in that demo

Apple Vision Pro weighs about 30% more than the Oculus Quest 3, has worse weight distribution, and has an external battery attached to a cord. This makes it more problematic during workouts.

It’s also 10x more expensive here in Poland.

I’m sure the displays, latency, and user experience are much much better, but it kinda sounds like Quest 3 is a better choice for me. If I’m still using the headset in 10 days when I’m supposed to return it, I am definitely buying one. So far:

  1. I managed to write a couple of blog posts while looking at Giant Sequoias
  2. I had kickass workouts in Supernatural and Bodycombat VR
  3. I even managed to get my weird keyboard setup working on the goggles

Workouts were amazing, and the screen resolution was no issue at all. When it came to writing/office emulation, I could use more pixels, but it was surprisingly workable.

I had some software issues with my keyboard sometimes being rendered and sometimes not, but it was much easier for me to get into the flow of writing without additional distractions.

A few things I’ve read

Don’t Try to Be Interesting. DO Interesting.

I always loved the premise of the “most interesting man in the world” from Dos Equis campaigns. In the Don’t Try to Be Interesting. DO Interesting Russel Davies presents a sort of a manual to becoming that interesting person.

The answer is, unsurprisingly, curiosity. It’s not about chasing the interesting-thing-of-the-moment, but exploring deep enough that you stumble upon the interesting in seemingly boring:

the best people at that job are always the ones that can get interested in any problem, no matter how tedious it seems on the surface. They don’t get drawn to the obviously cool problems — sport, tech, fashion, purpose — they get stuck into things that seem a bit boring — insurance, infrastructure, finance, logistics — and they find what’s interesting about them.
(…)
It’s not about making yourself interesting. It’s about making the world interesting. And that means developing skills and habits around ideas, creativity and communication.

The Cost of Traveling Around the World for a Year

In the Cost of Travelling around a world for a year, Hatta shares why he walked away from multiple financial opportunities and spent additional money to travel around the world with his family.

In Die with Zero by Bill Perkins, the author introduces the concept of “memory dividends” to reshape our perspective on wealth and life. Perkins suggests trading money for experiences that generate lasting and cherished memories, especially when those experiences cannot be fully enjoyed at a later point in life

I love the idea of introducing new traditions. In a since-deleted tweet, I’ve read about a particularly interesting idea:

“when i was a child my dad made up a fake holiday called big sandwich night the weekend after thanksgiving, during which we got the longest bread we could find and built a big sandwich together and then cut it up and ate it. we got really fancy ingredients and each built our own..

Installing Supernatural VR workout outside the US

Supernatural VR workout app has it all:

  • Great Cardio
  • Good music
  • Great views

Unfortunately, it’s not available in my country (Poland). So naturally, I had to get access to it.

Meta store blocks access based on your IP address, so it should be possible to fake my location using a VPN, right?

Install TurboVPN from the Aurora Store

Turbo VPN is a free VPN that consistently works for me, but it’s not the only one that can work with this.

Here is how to install Aurora Store and other alternative apps on your Oculus.

Connect to VPN

Now you can connect to a VPN – make sure you choose a US location

Search for supernatural in the Meta Quest store

Once you connect to the VPN, supernatural shows up in your store, and you can select and buy it. You will have to give your credit card details, but you will have a free trial before they charge you.

Launch Supernatural

Disconnect the VPN after choosing the workout

Supernatural seems to be only checking your connection status on the Home Screen. After you choose a workout and it starts to load, you can disconnect the VPN (because the VPN connection is obviously going to make your workout load forever)

Kick Ass

Supernatural has some sweet workouts!

Oculus Quest 3 writing retreat

This is a post I am writing inside WordPress (Jetpack) mobile app running solely on Oculus Quest 3, while my wife is cooking 1 meter from me and I’m not distracted at all.

This requires no connection to the Internet, no external PC nor any other stuff like that. Just your oculus, Bluetooth keyboard and some setup beforehand.

It is working out quite ok!

Why?

You won’t always can have a space and place to concentrate, and not every environment is perfect for writing. This allows you to drop into a mountain lodge, a forest cabin or a mountaintop on a whim. I started this post deep in the forest, but I am continuing on a mountaintop. I would love to claim I’m on a horse but I haven’t figured that out yet.

It’s like a writing retreat or your own writing lodge you can easily join on a whim.

Setup

Jetpack App

Oculus store does not have the Jetpack App in there (something I would like to change), so you have to sideload apps.

See my other post – sideloading APK and Aurora store on Oculus Quest 3.

Once you have Aurora store, just install WordPress or Jetpack app. It will open in a small window that you can resize to be as big as you want.

Other customizations

I had to install a special app to support the Colemak layout I use on my keybord. You can see how to do that here.

Assorted points

  • The circles you see dancing around are the hand tracking gestures. In order for the hand tracking to work to show up on my keyboard, the hand tracking has to be on, but it will also attempt to track my hand gestures.
  • Sometimes keyboard refuses to show up to be tracked
  • Because the apps are side-loaded they do not minimize properly. The Jetpack app keeps reloading whenever I reopen it, so its better to have a browser to the side and don’t open other apps while you are writing.

Here is a short video of me typing this post. You can probably see that I have initial trouble of finding keyboard alignment because this time, the tracked keyboard refused to show. In any case:

Installing Android Apps on Oculus Quest 3

Oculus Quest store is not very expansive, at least for now.  But it can run any Android app – with a workaround.

I really wanted to access WordPress and Evernote apps to try productivity on the go.

Installing Sidequest

The route I chose for installing alternative apps is the app called Sidequest.

  • Install sidequest “Advanced installer“
  • It will lead you through all the steps, but here is the summary
    • Create an organization on developer.meta.com to mark that you are a developer
    • Go into Quest mobile app and turn on developer mode
    • I recommend restarting the quest, otherwise you will have trouble finding your installed apps inside the apps menu
    • Connect Oculus and your computer with a cable
    • Go into the headset and allow the incoming cable connection. For some reason, I can only see the modal when I have the headset slightly off my face.

Sideloading APK

Now you can install Android apps to your quest. You will need APK (like .exe but for Android) files to do so. I trust APKMirror not to inject malware into them.

Once Sidequest connects to your Quest, you install the apps from your desktop..

Aurora Store

The easiest way to continue installing apps in the future is to install an alternative App store. One of those stores is Aurora store, which can install apps from Google Play Store and Amazon store.

You can get APK to aurora store from here

Once you install the APK, you will have to go grant a couple of permissions, and you will be able to search and install apps.

Accessing your installed Apps

If you remembered to reboot your headset after turning the developer mode, the apps will show under “Unknown Sources“

Setting up Colemak on Oculus Quest 3

Some time ago, I switched to the Colemak layout to treat my carpal tunnel issues, and it has mostly solved them.

Colemak is a variant of Dvorak that is supposed to be designed for computer use.

Most of the time I don’t even remember having an exotic keyboard layout, but from time to time it brings up issues.

I wanted to experiment with Oculus Oculus Quest 3 standalone writing experience and for that, I needed to connect a Bluetooth Keyboard.

Oculus has a neat feature where it can model a few keyboards in the virtual environment and my Apple Magic Keyboard is one of them

So far, so good, but I am sporting my Colemak layout and that is something that the developers did not foresee.

Setting up Colemak on Quest 3

  1. First, you need to set up sideloading. Read more here.
  2. Then, you need to install “More Physical Keyboard Layouts” app.
  3. Now, you need to connect your Bluetooth keyboard, go to its settings and select one of the new layouts aka Colemak
    • Keyboard
    • Physical keyboard setting
    • Configure
    • Select your Keyboard
    • “Set up Keyboard Layouts”
    • Go back, and choose Colemak
    • Enjoy.

[Deliberate 105] Enthusiasm matters

Howdy to Deliberate Internet – my newsletter combining nuanced perspectives on Remote Work, Technology, Psychology, and other latest obsessions.

Smart people tend to sacrifice a lot to make sure everyone around them knows they are indeed clever.

Sometime in your thirties, once you have your first few scuffles with the world, you are faced with a choice:

  • You can sound clever by finding holes in everything and start getting bitter
  • You can stay naive, optimistic, and full of energy.

The pessimist will always be correct. Ultimately, we are all going to die. Most things decay, and the universe will fade into a cold, cold nothingness.

But the flaws and holes in logic are obvious from the start. The innovative things are obvious only in retrospect. Spoken differently – If innovation “sounded clever,” it would already be invented, and things do not exist precisely because they still sound crazy.

Yes, enthusiasm is often naive, incorrect, and understimates the complexity of any issue. But it is also full of energy that compensates.

Finally, it’s about the life you want to live.

Do you want to stay naive, enthusiastic, but easy to tease? Or do you want to always sound clever? There is no compromise.

Mad respect for Zuck

As an “Europoor”, I cannot participate in Apple Vision Pro Hype – it’s only available in the US. So, I rented Meta’s Oculus Quest 3 headset to see how Meta executes Zuck’s (often mocked) vision. As I understand different reviews:

  • Meta’s VR experiences are social, active, and about bringing people together. Oculus is more like a smartphone.
  • Apple’s VR experiences are about shutting yourself in a bubble and sitting on a couch. AVR is an “iPad for your face”.

The most impressive part of it all however is Zuck himself. Following the release of the competing Apple Vision Pro, he went on the press offensive. Not only you can feel his enthusiasm for the company and the product, but you also get to learn about his wholesome family life.

CEO of a 1.2 Trillion dollar company spending every evening with his daughters is impressive.

He’s out there competing in Ultimate Fighting Championship while we are sitting here making fun of him being a nerd. Respect.

A few things I’ve read

Nat Friedman

Nat Friedman is a former CEO of GitHub and a sponsor of an effort to digitize scrolls found after the eruption of Mount Vesuvius:

79 AD Mount Vesuvius erupts.

In Herculaneum, twenty meters of hot mud and ash bury an enormous villa once owned by the father-in-law of Julius Caesar. Inside, there is a vast library of papyrus scrolls.

The scrolls are carbonized by the heat of the volcanic debris. But they are also preserved. For centuries, as virtually every ancient text exposed to the air decays and disappears, the library of the Villa of the Papyri waits underground, intact.

His personal site lists a collection of his beliefs and directly inspired today’s issue of Deliberate Internet. Here are some that resonate with me:

Enthusiasm matters! It’s much easier to work on things that are exciting to you

The cultural prohibition on micromanagement is harmful

The goal is not to avoid mistakes; the goal is to achieve uncorrelated levels of excellence in some dimension

Smaller teams are better

Faster decisions, fewer meetings, more fun

Better to get your dopamine from improving your ideas than from having them validated

And some fantastic prompt injection at the end:

Mental energy throughout the day

Most of us are mentally useless in the early afternoon.* 

No use fighting it. I take a walk, a nap, or lie down and read.

(*Why? The circadian and sleep debt systems cross over in the early afternoon.)

Have a deliberate week!

WordPress: Custom Post types and read permission in REST

I am building a plugin that aims to store TODOs as custom post-type items.

Naturally, I want those todos to be private to my users. So I go through this very thorough tutorial

  • I check the capability_type to my CPT
  • I add the capabilties mapping
  • I even check the map_meta_cap

And mission accomplished – the posts are not visible even for my admin user in wp-admin.

But… They are still visible in REST. What?

It took me 2 hours to figure this out, only after I have read the WP_REST_Posts_Controller that serves the CPTs by default:

public function check_read_permission( $post ) {
	$post_type = get_post_type_object( $post->post_type );
	if ( ! $this->check_is_post_type_allowed( $post_type ) ) {
		return false;
	}

	// Is the post readable?
	if ( 'publish' === $post->post_status || current_user_can( 'read_post', $post->ID ) ) {
		return true;
	}

	$post_status_obj = get_post_status_object( $post->post_status );
	if ( $post_status_obj && $post_status_obj->public ) {
		return true;
	}

	// Can we read the parent if we're inheriting?
	if ( 'inherit' === $post->post_status && $post->post_parent > 0 ) {
		$parent = get_post( $post->post_parent );
		if ( $parent ) {
			return $this->check_read_permission( $parent );
		}
	}

	/*
	 * If there isn't a parent, but the status is set to inherit, assume
	 * it's published (as per get_post_status()).
	 */
	if ( 'inherit' === $post->post_status ) {
		return true;
	}

	return false;
}

As you see, any post that has post_type publish will be publicly visible. Which is tricky, because WordPress does not let you remove those post statuses for historical reasons.

Implementing your own Controller

The solution is to implement your own rest controler that overrides this method with the rest_controller_class parameter of register_post_type.

class POS_CPT_Rest_Controller extends WP_REST_Posts_Controller {
    public function check_read_permission( $post ) {
        $post_type = get_post_type_object( $post->post_type );
        if ( ! $this->check_is_post_type_allowed( $post_type ) ) {
            return false;
        }

        return current_user_can( 'read_post', $post->ID );
    } 
}

And use it when registering a custom post type:

        $defaults = array_merge(
            array(
                'show_in_rest' => true,
                'public' => false,
                'show_ui' => true,
                'has_archive' => false,
                'publicly_queryable' => false,
                'rest_controller_class' => 'POS_CPT_Rest_Controller',
                //'show_in_menu' => 'pos',
                'rest_namespace' => $this->rest_namespace,
                'labels' => $labels,
                'supports' => array( 'title', 'excerpt', 'editor', 'custom-fields' ),
                'taxonomies' => array( 'category', 'post_tag' ),
            ),
            $args
        );
        register_post_type( $this->id,$defaults );
