J’accuse is one of the many iconic films we’ll explore in this series. The interwar period is when European cinema really starts to hit its stride again after some serious setbacks during the Great War. In those years, American cinema rocketed to the mainstream both at home and abroad, with revolutionary filmmaking techniques being developed that we still see today such as close-ups, huge cast lists, and realistic set design.The post-Great War is set to be a great era in the history of cinema and not just because of the films themselves, J’accuse and other films are important as historical movers in their own right! They shape public perceptions, influence political change, and inspire whole social movements, so make sure you stay tuned to find out.
And in the meantime, are there any iconic interwar films you think deserve to be in this series?

QotD: The Smartphone, the Eater-of-Gadgets
I’ve been thinking for some time now that the smartphone has achieved a kind of singularity, becoming a black hole that sucks all portable electronics into itself. PDAs – absorbed. Music players – consumed. Handset GPSes – eaten. Travel-alarm clocks, not to mention ordinary watches – subsumed. Calculators – history. E-readers under serious pressure, and surviving only because e-paper displays have lower battery drain and are a bit larger. Compasses – munched. Pocket flashlights – crunched. Fobs for keyless locks – being scarfed down as we speak, though not gone yet.
[…]
But in an entertaining inversion, one device of the future actually works on smartphones now. Because I thought it would be funny, I searched for “tricorder” in the Android market. For those of you who have been living in a hole since 1965, a tricorder is a fictional gadget from the Star Trek universe, an all-purpose sensor package carried by planetary survey parties. I expected a geek joke, a fancy mock-up with mildly impressive visuals and no actual function. I was utterly gobsmacked to discover instead that I had an arguably real tricorder in my hand.
Consider. My Nexus One includes a GPS, an accelerometer, a microphone, and a magnetometer. That is, sensors for location, magnetic field, gravitational fields, and acoustic energy. Hook a bit of visualization and spectral analysis to these sensors, and bugger me with a chainsaw if you don’t have a tricorder. A quad- or quintcorder, actually.
And these sensors are already completely stock on smartphones because sensor electronics is like any other kind; amortized over a large enough production run, their incremental cost approaches epsilon because most of their content is actually design information (cue the shade of Bucky Fuller talking about ephemeralization). Which in turn points at the fundamental reason the smartphone is Eater-of-Gadgets; because, as the tricorder app deftly illustrates, the sum of a computer and a bunch of sensors costing epsilon is so synergistically powerful that it can emulate not just real single-purpose gadgets but gadgets that previously existed only as science fiction!
[…]
I specified “personal” radios because radios have something in common with personal computers; their main design constraints are actually constraints on a peripheral stage. For a computer you’ll be using for hours at a time you really want a full-sized hard keyboard and a display bigger than a smartphone’s; for a really good radio, the kind you supply sound for a party with, you need speakers with resonant cavities that won’t fit in a smartphone enclosure.
Digital cameras are another diagnostic case. The low-end camera with small lenses is already looking like a goner; the survivors will be DSLRs and more generally those with precision optics too large and too expensive to fit in a phone case.
These two examples suggest Raymond’s Rule of Smartphone Subsumption: if neither the physics nor the ergonomics of a gadget’s function require peripherals larger than will fit in a smartphone case, the smartphone will eat it!

The watchful algorithms of the Nanny State’s AI tools
David Warren considers the evolution of the Nanny State’s arsenal of technological surveillance (supplemented by the Karenstapo):
While it is not in my interest, currently, for gentle reader to get off the Internet, the idea must have occurred to him. In times like these, why put yourself under watch from Big Brother (or, Big Sibling, as he might prefer)? Why surround yourself with his electronic eyes, the way I am presently surrounded by jackhammers?
Granted, Nanny State was devising ways to track its citizens, and to exercise “crowd control,” long before the Internet was invented. But we had the advantage with them, for they were incompetent, often laughably inept. However, Internet-plus-meejah-plus-activists-plus-Guvmint makes a more capable adversary.
I am not recommending a systematic withdrawal from the world. That is for people with a religious calling, or some grave eccentricity. Rather I am thinking of self-defence, in the spirit of buying a gun. Of course, I am writing from Canada, one of the countries where owning a gun is more-or-less illegal; as is any other form of self-defence. (“When seconds count, the police will be here in minutes.”) Though I have noticed that, upcountry, the “No Hunting” signs tend to be used for target practice.
The “other side,” as I see it, which always worked on numbers, now has algorithms. “Artificial Intelligence” can home right in. The Nanny State never took the individual seriously, except when he was offering a threat. Now it is threatened by anything human. It is, as it were, utilitarian in outlook — “the greatest good for the greatest number” — along with other fatuous concepts, unamenable to reason. By its nature, it is positivist, nominalist, relativist, and “idealistic” in a very abstract way.
Whereas we, so far as we are human, take ourselves quite personally. In a clinch, we often prefer our own survival, and the survival of family and friends, to the requirements of a bureaucratic “policy.” That this is “selfish” should be immediately affirmed.
Because the masses are now deprived of a Christian education, they misconstrue the “selfishness” of Christian teaching, which tells us that we ought selfishly to become saints. Our intention should be to get ourselves to Heaven, along with any we know who can be taken with us. But charity is not “selfish,” in ways they understand. Under modern tenets of “multiculturalism,” even fidelity to the old Christian view is decried as a form of selfishness, calling out for persecution. For this is because it is “cultural,” not “multi” — for all the many languages it speaks.
Our enemy wants us to eschew uniqueness, and become instead “diverse” — by which it means homogenized and narrowly interchangeable. Increasingly, this adversary has the means to enforce its arbitrary will.

QotD: What the GDP is failing to show (even though it’s there)
There simply isn’t a technology that has come anywhere close to arriving in the hands of actual users as fast as the smartphone and mobile internet. The next closest competitor is the mobile phone itself. All others running distant third and behind.
Our problem is that we know technological revolutions produce growth. Yet economic growth is limp at best, meagre perhaps a better description. So, there’s something wrong here. Either our basic understandings about how growth occurs are wrong and we [are] loathe to agree to that. Not because too much is bound up in that understanding but because too much of it makes sense. The other explanation is that we’re counting wrong.
[…]
We know that we’ve not quite got new products and their falling prices in our estimates of inflation quite correctly. They tend to enter the inflation indices after their first major price falls, meaning that inflation is always overstated. Given that the number we really look at is real growth – nominal growth minus inflation – this means we are consistently underestimating real growth.
[…]
The more we dig into this the more convinced I am that our only real economic problem at present is counting. Everything makes sense if we are counting output and inflation incorrectly, under-estimating the first, over- the second. If we are doing that – and we know that we are, only not quite to what extent – then all other economic numbers make sense. We’re in the midst of a large technological change, we’ve full employment by any reasonable measure, wages and productivity should be rising strongly. If we’re mismeasuring as above then those two are rising strongly, we’re just not capturing it. Oh, and if that’s also true then inequality is lower than currently estimated too.
The thing is, the more we study the details of these questions the more it becomes clear that we are mismeasuring, and mismeasuring enough that all of the claimed problems, the low growth, low productivity rises, low wage growth, simply aren’t there in the first place. And if they ain’t then nothing needs to be done about them, does it? Except, perhaps, count properly.

Speaking in code and public health
In The Line, Joshua Hind relates the tragedy that forced US emergency services to wean themselves off their many confusing (and sometimes conflicting) spoken codes and use plain language to help reduce tragic misunderstandings among different emergency response organizations:
In the beginning, it was standardized, and the best-known codes, like “10-4,” were consistent from town to town or state to state. But it didn’t take long for newer codes to emerge, which often meant different things depending on where you were. Efforts to reorganize the codes every 20 years or so only compounded the problem. On a local level, in any one town, it wasn’t a problem. But when cops or firefighters from different towns had to work together it could lead to disaster.
In 1970, a particularly severe wildfire season in California killed 16 people in a 13-day period and laid bare the cost of bad interagency communication. The rat’s nest of codes, abbreviations, and jargon prevented firefighters from different towns from communicating with the speed and clarity a major disaster demands. To address the problem, the U.S. Forest Service created FIRESCOPE, the first complete system for organizing and managing major incidents. One of the primary principles of this new system was to “develop standard terminology.”
Despite this effort, which later went national and then international (the province of Ontario has its own version, the “Incident Management System”) coded language continued to proliferate. Nearly 30 years after FIRESCOPE was launched, on September 11th, incompatible technology, lack of protocols, and a refusal to harmonize terminology likely contributed to the deaths of 121 firefighters who were caught in the collapse of the North Tower because they either didn’t hear or couldn’t understand the warnings that the building was about to fail.
Which brings us back to 2006, and FEMA’s notice to first responders. After decades of asking agencies to stop using coded language, the federal government made funding contingent on compliance. “The use of plain language in emergency response is a matter of public safety,” the memo’s introduction read. “There simply is little or no room for misunderstanding in an emergency situation.” From that point forward, all interdepartmental communication would have to be un-coded. A fire would be called “fire.” A shooting would be “a shooting.” And if you needed help, you’d say “HELP!”
Police, fire departments and paramedics slowly but surely got on board and started using some form of the incident management system which included plain language. As use of the system spread, other sectors, like large music festivals and other live events, began adopting the concepts to better synchronize public safety programs with the first responders who support them. Today it’s not unusual for producers, technicians and event security staff to attend training at the police college right next to fire captains and police officers.
Then COVID-19 happened, and we realized that no one had told Public Health.

English lead and the European markets of the 1600s
In the latest Age of Invention newsletter, Anton Howes considers the meteoric rise in lead production in England and Wales from the dissolution of the monasteries under Henry VIII to the Thirty Years’ War in Europe:
In the early sixteenth century, England was a minor producer of the stuff. It was widespread and cheap enough to be used for roofing buildings (unlike much of the rest of Europe, where copper was preferred), but the country never produced more than a few hundred tons per year. It didn’t really need to. Like stone in [the game] Dawn of Man, you could amass a stockpile and not worry too much about any leaky bucket problems [where stockpiles need to be replenished due to wastage or other “drains”]. The lead in roofs could always be recycled, and hardly any more was needed for pipes or cisterns. The vast majority of the demand came from Germany, and then the New World, where it was used to extract silver from copper ore. Even this dissipated in the mid-sixteenth century, when the New World silver mines began to switch to using mercury instead.
Yet by 1600, England was producing about 3,000 tons of lead a year, up from just 300 in the 1560s. By 1700, it was producing two thirds of Europe’s lead — a whopping 20,000 tons a year. How?
Unlike copper or iron, there is no evidence that lead mining or processing techniques were imported. If anything, they seem to have emerged from the Mendips, in Somerset, where production costs fell with the introduction of furnace smelting in the 1540s. As well as raising the extraction rates from the ore coming up from the mines, the new furnaces allowed previously unusable ores — found in the easily-accessible waste tips of old mining camps — to be smelted after some simple sifting. Unfortunately, we don’t have a clear idea of who was responsible for the innovation.
Yet the source of England’s supremacy was really, at first, religious. Following the dissolution of the monasteries by Henry VIII in the 1530s, the melting down of their roofs dumped some 12,000 tons of lead onto England’s markets — at least a year’s worth of Europe’s entire output. Although the immediate effect was to annihilate England’s own lead industry, the medium-term effect was to send the other European producers into disarray. By the 1580s, once the stockpile had depleted, England’s lead producers were among the only ones left standing. The sale of monastic lead ensured that the English retained a foothold in foreign markets, while the cost-saving innovations then gave them the competitive edge. These factors explain, at least, England’s eventual hold over the European lead market.
But there was yet another phenomenon responsible for the industry’s massively increased scale: the development of hand-held firearms. Gunpowder technology was of course centuries old, but cannon had largely fired balls made of stone or cast iron. Muskets and pistols, however, used bullets made of lead. With the proliferation of the weapons over the course of the seventeenth century, lead thus acquired a major leaky bucket problem. Bullets were too costly to recycle, leading to an estimated fifth of Europe’s annual production of lead disappearing every year — a wastage that only increased as armies grew, weapons’ rate of fire improved, and the continent experienced extraordinary violence. Europe lost an estimated fifth of its population to the Thirty Years’ War, and England itself succumbed to civil strife.
England’s lead industry thus had to drastically increase its production just to maintain Europe’s stock of lead, let alone increase it. It was from soldiers entering the fray, to trade bullets across sodden fields, that it owed its extraordinary success.

Perdition to Conspirators! Magnificent 14-Barrel Flintlock
Forgotten Weapons

Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
Colonel Thomas Thornton was a wealthy and somewhat flamboyant character in England in the late 18th and early 19th century. He commanded a militia unit with which he had some disagreement, and which mutinied against his comment at Roborough Camp in 1795. Some years later, he commissioned this quite unique firearm from Dupe & Company of London.
The gun is a single stock with two flintlock actions, two triggers, and two clusters of seven .30 caliber rifled barrels each. Each trigger fires a complete barrel cluster simultaneously. In addition to the firepower of this very remarkable weapon, he also had it finished in a truly magnificent fashion, including the fantastic line “PERDITION TO CONSPIRATORS” on ons of the barrel clusters — clearly he harbored some resentment towards his unruly militia subordinates even years later.
In addition, he had a second stock made to fit just one lock plate and barrel cluster, for when 14 barrels might be a bit of overkill. That stock is even more decorated that the first, with beautiful wooden relief carvings and the motto “A Verite Gagner“, meaning something to the effect of “Truth From Victory”.
This gun is part of the Liege arms museum’s display of civilian arms, and I’d like to thank them for taking it out of their display so I could show it to you! If you are in Liege, stop in and see the museum:

The perils and pitfalls of developing open source software
In The Diff, Byrne Hobart looks at the joys and pains-in-the-ass of open source software development:
We’re in a strange in-between state where software is increasingly essential, the most important bits of it are built by dedicated volunteers, and there’s no great way to encourage them to a) keep doing this, and b) stay motivated as the work gets less and less fun. That was my main takeaway from Nadia Eghbal’s Working in Public, published this week.
The book is a tour of the open source phenomenon: who builds projects, how they get made and updated, and why. This is an important topic! Almost all of the software I use to write this newsletter is either built from open source products or relies on them: the text is composed in Emacs, on a computer running Linux; I browse the web using Chrome, which mostly consists of open-source Chromium code; my various i-devices run Unix-based OSes (iOS is not open-source, but there are as many open-source implementations of Unix as you want); etc. All of this software Just Works, and I don’t directly pay for any of it. Clearly there are some incentives at work, or it wouldn’t exist in the first place, but generally the more complex an activity is, the harder it is to coordinate without pricing signals. Somehow, open-source projects don’t fall victim to this.
As Working in Public shows, they do face a demoralizing lifecycle. When a project starts, it’s one coder trying to solve a problem they face, and trying to solve it their way. Sometimes, there’s a good reason their preferred solution doesn’t exist yet, and the project languishes. Sometimes, the project catches on, acquiring new users, new contributors, and new bug reports and feature requests.
[…]
Software projects go through this exact cycle: at first, they’re mostly producing and building on “software capital,” code that executes the underlying logic of the process. Over time, more of the work involves integration and compatibility, and as all the easy edge cases get identified, the remaining bugs are a) disproportionately rare (or they would have been spotted by now) and b) disproportionately hard to fix (because they have to be the result of a rare and thus complicated confluence of circumstances). So, over time, a software project falls into the Baumol Trap, where high productivity in the fun stuff produces more and more un-fun work where productivity gains are hard to come by.
This is depressing for project creators. Early on, they have the triumphant experience of building exactly what they want, and solving their nagging problem. And the result is that they’re cleaning up after a bunch of requests from people who are either annoyed that it doesn’t work for them or have unsolicited feedback on how it ought to work. No wonder Linus Torvalds gets so mad. Running a successful open source project is just Good Will Hunting in reverse, where you start out as a respected genius and end up being a janitor who gets into fights.
Emphasis mine, not in the original article.
