The world in which IPv6 was a good design | Avery Pennarun

The Map Is Not the Territory: An Essay on the State of Economics | John Kay @ The Institute for New Economic Thinking
[In] 1995, Lucas described his seminal model [which] developed into the dominant approach to macroeconomics today, now called Dynamic Stochastic General Equilibrium. […] All science uses unrealistic simplifying assumptions. […] But Lucas and those who follow him were plainly engaged in a very different exercise […] The distinguishing characteristic of their approach is that the list of unrealistic simplifying assumptions is extremely long. […] Lucas was explicit about his objective – “the construction of a mechanical artificial world populated by interacting robots that economics typically studies”. […] Consistency and rigour are features of a deductive approach, which draws conclusions from a group of axioms – and whose empirical relevance depends entirely on the universal validity of the axioms. The only descriptions that fully meet the requirements of consistency and rigour are complete artificial worlds, like those of Grand Theft Auto […] Much of the modern research agenda of the economics profession is thus unconnected to the everyday world of business and finance. [… Becker claims that] a priori deduction from a particular set of unrealistic simplifying assumptions is not just a tool but “the heart of the economic approach”. […] Believing that economics is like they suppose physics to be – not necessarily correctly – economists like Becker regard a valid scientific theory as a representation of the truth – a description of the world that is independent of time, place, context, or the observer. […] If there were to be such a universal model of the economic world, economic agents would have to behave as if they had knowledge of it […] This is a 𝘳𝘦𝘥𝘶𝘤𝘵𝘪𝘰 𝘢𝘥 𝘢𝘣𝘴𝘶𝘳𝘥𝘶𝘮 argument, which demonstrates the impossibility of any universal model – since the implications of the conclusion for everyday behaviour are preposterous [… But] since the followers of this approach believe strongly in the premise – to deny that there is a single pre-specified model that determines the evolution of economic series would, as they see it, be to deny that there could be a science of economics – they accept the conclusion that expectations are formed by a process consistent with general knowledge of that model. […] This is not science, however, but its opposite.

Toward Better Master Passwords | Jeff Shiner @ AgileBits
[To] get the most security out of it, you should combine Diceware with your own private system. Create a short random password, including digits and symbols and use that in place of one of the dicewords in your final password. So going back to my dogs, Molly and Patty, I might create a weak password like “2dM&P”, and suppose my rolls of the dice gets me “cleft cam synod lacy”, I could then create a master password like “cleft 2dM&P cam synod lacy”, which would be a very good master password.

Explaining White Privilege to a Broke White Person... | Gina Crosley-Corcoran
I, maybe more than most people, can completely understand why broke white folks get pissed when the word “Privilege” is thrown around. As a child, I was constantly discriminated against because of my poverty and those wounds still run very deep. But luckily my college education introduced me to a more nuanced concept of Privilege; the term Intersectionality. The concept of Intersectionality recognises that people can be privileged in some ways and definitely not privileged in others.

Why diversity matters (the meritocracy business) | Eric Ries
And yet, when I suggest this practice to hiring managers and recruiters alike, they rarely do it. Hiring managers say, “the recruiter would never go for it” while recruiters say, “the hiring manager won’t accept it.” What I think we’re really saying is: “I don’t want to know if I am biased.” That’s understandable – it’s embarrassing! Even if our biases are only implicit and not consciously held, the systems we build can still contain bias. When we change a hiring policy, especially if we do it in a visible way, we reap two benefits. We actually improve our hiring process and also signal our commitment to meritocracy.

Racism And Meritocracy | Eric Ries @ TechCrunch
I previously described on my blog one simple change I made to the hiring process at my last company. I asked all of our recruiters to give me all resumes of prospective employees with their name, gender, place of origin, and age blacked out. This simple change shocked me, because I found myself interviewing different-looking candidates – even though I was 100% convinced that I was not being biased in my resume selection process. If you’re screening resumes, or evaluating applicants to a startup school, I challenge you to adopt this procedure immediately, and report on the results.
I asked if they were planning to apply. Their response: “oh, no, it’s a waste of time. Y Combinator doesn’t accept people like me.” Where did they get that idea? Surely not from YC’s partners, who as far as I can tell are scrupulously fair in their dealings with entrepreneurs. Rather, they got that impression by inferring that there is probably implicit bias in YC’s admissions process, and that they’d be better off spending their time doing something else other than applying to YC. […] There are qualified minority applicants who are choosing – rationally – to invest their time and energy elsewhere.

Angry Birds, Farmville and Other Hyperaddictive ‘Stupid Games’ | NYTimes.com
Game-studies scholars (there are such things) like to point out that games tend to reflect the societies in which they are created and played. […] The enemy in Tetris is not some identifiable villain (Donkey Kong, Mike Tyson, Carmen Sandiego) but a faceless, ceaseless, reasonless force that threatens constantly to overwhelm you, a churning production of blocks against which your only defense is a repetitive, meaningless sorting. […]

When I spoke to Frank Lantz, the creator of Drop7, he seemed humbled by his own game. He said Drop7 felt less like something that he and his team had created than something they had discovered — “a little corner of the universe that people hadn’t visited before, that predates us and will be around after we’re gone.” […]

“There’s no word for that in English, for a thing that does both of those at the same time. But it’s wonderful.” I asked him if he knew a word for that in another language. He said no, but then he thought for a minute.

Things I don’t like about Twitter 4 for IOS
Much of what made Twitter useful in the first place – Hashtags, @user and many other little Twitter specific conventions are hacks that were first adopted by users because Twitter didn’t support several key functions like groups or addressing a note to a specific user. Twitter has made the mistake of trying to integrate these workarounds into the base DNA of their service.


Twitter appears to have fallen into the trap of blindly listening to its users and failing to understand what its users are trying to accomplish. Don’t pay attention to what your users ask you for, pay attention to what they are trying to achieve.

Free Energy and the Meaning of Life | Sean Carroll @ Cosmic Variance
Because the Second Law of Thermodynamics tells us that entropy increases, the history of the universe is the story of dissipation of free energy. Energy wants to be converted from useful forms to useless forms. But it might not happen automatically; sometimes a configuration with excess free energy can last a long time before something comes along to nudge it into a higher-entropy form. Gasoline and oxygen are a combustible mixture, but you still need a spark to set the fire. This is where life comes in, at least according to one view.

How To Destroy A Black Hole | arXiv blog
What would a black hole without its event horizon reveal? That’s where physics turns philosophical. The mathematics here indicates that spacetime becomes infinitely curved, creating what astrophysicists call a singularity. ¶ To any ordinary physicist, a singularity is an indication that a theory has broken down and some new theory is needed to describe what is going on. It is a matter of principle that singularities are mathematical objects […] Astrophysicists are different. They have such extraordinary faith in their theories that they believe singularities actually exist inside black holes. The likes of Roger Penrose and Stephen Hawking have even proved that singularities are inevitable in gravitational collapse. ¶ For them, removing the event horizon around a black hole raises the exciting prospect of revealing a singularity in all its naked glory. When that happens, we will be able to gaze at infinity.

In the lab the user’s values, knowledge, and incentives are those of the tool builder, since the user and the builder are the same person. Deployment leads to severe fission; users often have little understanding of the tool and little interest in helping develop it (for reasons ranging from simple skepticism to perverse reward incentives) and typically label any error message they find confusing as false. A tool that works well under these constraints looks very different from one tool builders design for themselves. [[Followed by a veritable litany of social problems. —Ed.]]

Personify every object | Joel Stickley @ How To Write Badly Well
The hat, old and disillusioned, sat on Leo’s head like a passenger on a bus which is not only late, but has forgotten which route it was supposed to be taking. The feather drooping pathetically from the hat’s side seemed to have given up any hope of escape and was now, to all intents and purposes, playing dead. Leo shuffled his shoes, which were not having the best day, on the gravel; first the chewing gum they had picked up two miles back and now this. As for the chewing gum, it was just disappointed to be stuck to a pair of shoes with such a low tolerance for discomfort.

Leo’s grimy, tactless finger hovered hesitantly over the unsuspecting doorbell for a second before pushing it. The sound of the chimes filled the inside of the house like a sumo wrestler in a minicab before dying away like a sumo wrestler on life support. The silence which followed outstayed its welcome like a guest at a party which didn’t want to be thrown, much like a shot-putt entertaining thoughts of retirement in a country cottage which sits contentedly on a hilltop which reaches for the clouds like a dieter for cream cakes which wish they didn’t have to be eaten.

“Open Source is to Traditional Software as Terror Cells are to Large Standing Armies – if you gave a terrorist group a fighter jet, they wouldn’t know what to do with it. Open source teams, and culture, have been developed such that they’re almost money-agnostic. Open source projects run on time, not money. So, the way to convert that currency is through bounties and funded internships. Unfortunately, setting those up takes time, and since that’s the element that’s in short supply, we’re back to square one.” —John Galloway

What are financial derivatives? | Ben Tilly
So there we have it. Financial derivatives are just contracts. People enter into them for all sorts of reasons. They are traded in large volumes. They can be arbitrarily complex. They can mitigate or create risk. We have theories on how to price them. When financial derivatives are set up correctly, apparently free money is created. This money comes with associated risk. Honest mistakes about the pricing or risks can lead to disaster. Warren Buffett has written on this topic with extreme warnings about this exact issue. Securitization is a way of bundling lots of little streams of cash into nice bonds. Securitization brought us increased local financial stability, which has been to our general benefit. But systemic mistakes in securitization also brought us a real risk of global collapse. ¶ If you understood that then you likely understand financial derivatives better than half the talking heads you see on TV.

Historically, [… y]ou began by doing the work, and if you got good at it, you ended up telling other people with less experience or less competence how to do it instead.

[…] Making management a profession was arguable; the associated notion that you could manage workers with no understanding of what they did was a disaster.

A hard rain's gonna fall on exoplanet COROT-7b
COROT-7b has a similar density and silicate rock makeup to that of Earth. However, the planet and its host star are separated by only 1.6 million miles […] One side of COROT-7b […] is thought to have a temperature of 4220°F [2330°C]. ¶ As rocks vaporize at that heat it is believed that COROT-7b’s precipitation is pebbly. But when a “front moves in” pebbles condense out of the air and run into lakes of molten lava on the surface below. Scientists used a computer system that ran different variants yet yielded consistent results – rock showers. ¶ Much like the Earth’s atmosphere causes water cloud to form resulting in water droplets, COROT-7b’s atmosphere is believed to form rock clouds that then rain little pebbles and other forms of rock.

What to Know Before Debating Type Systems | Chris Smith
Dynamic and static type systems are two *completely* different things, whose goals happen to partially overlap. A static type system is a mechanism by which a compiler examines source code and assigns labels (called “types”) to pieces of the syntax, and then uses them to infer something about the program’s behaviour. A dynamic type system is a mechanism by which a compiler generates code to keep track of the sort of data (coincidentally, also called its “type”) used by the program. The use of the same word “type” in each of these two systems is, of course, not really entirely coincidental; yet it is best understood as having a sort of weak historical significance.

If these kids knew their history, they’d see that the office anti-sexism is a bit of a sham and their attempts to be contrary to office culture would lean them to be honestly, legitimately egalitarian.

This works much better than comparing test pages to reference images (although you can use an image as a reference if you want), because you can easily write tests that work no matter what fonts are present, or what the platform form controls look like, or what platform antialiasing behaviour is, and so on. There are almost always many ways to achieve a particular rendering effect in a Web page, so it’s very easy to write reftests for parsing, layout, and many rendering effects.

You’re sitting at a party, you decide “I don’t like this; I don’t want to be here.” And then you don’t leave. That kind of social stickiness is what Bion is talking about. And then, another really remarkable thing happens. 20 minutes later, one person stands up and gets their coat, and what happens? Suddenly everyone is getting their coats on, all at the same time. […] There’s this very complicated moment of a group coming together, where enough individuals, for whatever reason, sort of agree that something worthwhile is happening, and the decision they make at that moment is: This is good and must be protected. And at that moment, even if it’s subconscious, you start getting group effects. And the effects that we’ve seen come up over and over and over again in online communities.

The System of the World Wide Web: How the Web won | Leonard Richardson
I think the web won because of the URI. Go ahead, laugh. That’s what people did when these cryptic addresses started showing up in magazine ads. And on billboards. And business cards. And television.

The Internet’s Chorus of Calumny | Rogers Cadenhead
For all of the talk about how bad it is to be the focus of an angry mob, an angry Internet mob gums its prey rather than biting. Once you get used to the slobber it’s not so bad.

Narcissism of small differences | Wikipedia
The term describes the manner in which our negative feelings are sometimes directed at people who resemble us, while we take pride from the “small differences” that distinguish us from them.

Why, oh WHY, do those #?@! nutheads use vi?
Your keyboard becomes a huge specialized text-editing gamepad with almost a hundred buttons. […] You have the best-designed text-editing machine there is, and it shows. [[Great examples and thoughtful myth rebuttals showing what makes vi great. —Ed.]]

The case of the 500-mile email | Trey Harris
I almost regret posting the story to a wide audience, because it makes a great tale over drinks at a conference. :-) […] “Yes, and she’s produced a map showing the radius within which we can send email to be slightly more than 500 miles.”

Bassline Baseline, 2005 | Nate Harrison
A video essay that investigates the invention, failure and subsequent resurrection of the mythic Roland TB-303 Bass Line music machine in the last two decades of the 20th century. The narrative seeks to invite thoughts on technological mediation within product innovation and creative expression. The dead-panned “documentary” video attempts to explore how and why creative tools fail and how increasingly more options, parameters or intermediaries devised during a tool’s research and development phase don’t necessarily lead to increased expressivity or virtuosity during the tool’s lifetime of actual use, unless the super-structure of its cultural context is dramatically reconsidered.

Can I Get An Amen?, 2004 | Nate Harrison
A critical perspective of perhaps the most sampled drum beat in the history of recorded music, the Amen Break. It begins with the pop track Amen Brother by 60’s soul band The Winstons, and traces the transformation of their drum solo from its original context as part of a “B” side vinyl single into its use as a key aural ingredient in contemporary cultural expression. The work attempts to bring into scrutiny the techno-utopian notion that “information wants to be free” – it questions its effectiveness as a democratizing agent. This as well as other issues are foregrounded through a history of the Amen Break and its peculiar relationship to current copyright law.

Notes from the [Varnish] Architect | Poul-Henning Kamp
I have spent many years working on the FreeBSD kernel, and only rarely did I venture into userland programming, but when I had occation to do so, I invariably found that people programmed like it was still 1975.

Conversions: All in a Day’s Work | Arjen Poutsma
Each library used a different string, so conversion was all in a day’s work. Imagine my joy when I started programming in Java, some 10+ years ago. “Woohoo! Just one string type! And garbage collection too!”

All markup ends up looking like XML | David Megginson
Nearly all comparisons between XML and JSON look something like this, and I have to admit, it’s a slam dunk […] On the other hand, I rarely see any data structures that are really this simple, outside of toy examples in books or tutorials

Your paranoia is justified | Brennen Bearnes
The government where you live is careening ever-closer to a totalitarianism overhauled by the fundamental realization that mundane and implicit evil mixed well with broadcast commercial soul-rot has a half-life that makes Stalin and Hitler look like complete chumps.

On the Goodness of Binary Search | Tim Bray
There’s a story I heard from a prof, that the basic Binary Search idea was around when Alan Turing was still in diapers, but that the first 18 published implementations were buggy. And I know for a fact that the first few times I coded it I got it wrong. […] So the recipe is: […] Once you get used to it, you can code it up without having to think too much. I got the body of the `search1` method up there right, character for character, the first time I typed it in.
