So since this is in the firmware is it safe to assume that this affects all devices with the broadcom chip, regardless of what OS they're running?

Tech design choices can have profound social impact.

This is just a personal theory, but I suspect Twitter's choices have done huge damage to Western Civilization, by forcing, as a medium, a very short 'soundbite' structure onto debate. (Even more so than the media which gave us the term 'soundbite' ever did!)

So that sounds like a very overblown assertion, right?

But think about Trump. Twitter is his platform, and arguably he is the sort of President a platform like Twitter most directly enables. He gets direct unchallenged access to a mass medium, a mass medium which makes it particularly hard to counteract false claims or have reasoned debate. For exactly the issues Antirez is raising.

I don't have evidence to support my theory, all I can say is I don't think I want Twitter to succeed.

Twitter is annoying. I signed up a couple years ago to follow some local stuff's news, mostly events. Thus I followed 8-9 accounts that initially were of my interest, and started refreshing and reading my feed. All I got was the same 3-4 posts repeated annoyingly often, so that I had to fish for new things that sink below stuff reposted almost hourly since months. I though, well, maybe it's these accounts that I follow that don't know what to do, and started looking around. What I found is that there are 3 prominent Twitter stereotypes: (i) the reposter, which repeatedly posts the same thing and retweets anybody who mention them, (ii) the dumper, like news sites etc., which just vomit tweets at you one every other minute, and (iii) the spartan which speaks in semi-cryptic punchlines. Given the platform has no spam filtering or any way to indicate whether a post is seen or not, it's byzantine task to extract information from what you get served in your feed.

Well the fundamental chosen limitations of the service seem to make it a bad choice for detailed technical arguments. But ultimately social networks are just about who is there. We talk about technical topics on twitter not because it's the right forum, but because the people we want to talk to are there.

Potentially relevant, since the article draws a comparison between twitter discussions and (what used to be) usenet discussions: https://en.wikipedia.org/wiki/Eternal_September

Twitter seems to support less of a netiquette, it's more point-and-shoot. Besides that, it seems intuitive that the 140 chars restriction lends itself less to discussions than proper forums.

Yes, YES, this is what I'm talking about Microsoft. I'm surprised how muted the reaction is from HN here.

On the technical side, this is a perfect example of how AI can be used effectively, and is a (very obvious in hindsight) application of the cutting edge in scene understanding and HCI. There are quite a few recent and advanced techniques rolled into one product here, and although I haven't tried it out yet it seems fairly polished from the video. A whitepaper of how this works from the technical side would be fascinating, because even though I'm familiar with the relevant papers it's a long jump between the papers and this product.

On the social side, I think this is a commendable effort, and a fairly low hanging fruit to demonstrate the positive power of new ML techniques. On a site where every other AI article is full of comments (somewhat rightfully) despairing about the negative social aspects of AI and the associated large scale data collection, we should be excited about a tool that exists to improve lives most of us don't even realize need improving. This is the kind of thing I hope can inspire more developers to take the reins on beneficial AI applications.

If I have a friend that is visually impaired and is using this, I have to consent to their phone recording me and analyzing me and sending all of that data off to who knows where.

And this is just from my perspective - someone who is not visually impaired. For the person who is, every single thing they look at and read is going to be recorded and used.

It's an unfortunate situation for people to put in, and I'm sure everyone will choose using improvements like this over not using them. As much as I would love to see a focus on privacy for projects like this, I don't imagine it happening any time soon, given how powerful the data involved is.

On being the employee who needs improvement virtuouscode.com

The key to being a successful remote worker is a foundation of trust. It is imperative to establish a reputation where your co-workers trust you to do the right thing even if you're not available every second of the day. The moral of the story is not about abusive bosses or misaligned corporate goals. It is a failure in maintaining that crucial level of trust in the team. Both manager and employee play a an active part in this trusting relationship. Personally I would never hire a remote worker I could not confidently trust nor would I work for a place that didn't implicitly trust me

Edit - I've been a remote worker for over 10 years and will likely continue as long as I possibly can

If you get to the point that you're on a personal improvement plan, you should immediately look for other work. There are no circumstances in which it will turn around.
humanrebar 3 hours ago 3 replies      
I don't know what the motivations for the bosses in this story were, but in corporate America personal improvement plans are fundamentally about gearing up to fire someone more than any actual improvement. When defending yourself against a wrongful termination lawsuit, it looks good to courts to say, "Look, we met every week, we had these conversations, and things didn't get better enough."

In the story linked, it seems like the author was prioritizing family or health over work at times (me: Good! We need more of that!). The employer can't just fire you for that as it looks a lot like wrongful termination. So they need to build up a paper trail.

ptero 1 hour ago 1 reply      
Leaving aside the clear miscommunication that led to the "needs improvement" state first, it seems to me the management did just fine after that:

1. They quickly and clearly told the employee of the problem.

2. They proposed a course of action

3. Their proposal worked (at the end they were happy with his work).

It was not pleasant for sure (for both sides, I bet), but would it be worse to say nothing and terminate him for non performance in a couple of extra months. My 2c.

OK I've being working remotely for close to 10 years, most places were very flexible about hours and taking time during the work day for family things etc. But one things none was ever flexible about is remote employees dropping off com. channels for days. I think that is clear abuse of trust and the main fear why so few jobs are remote in the first place.
throwme_1980 2 hours ago 1 reply      
I honestly think your employers have been super generous already, one ought to know what is expected of him/her and realise they shouldn't leave themselves open to criticism by abusing the trust of the employer, always be in a positive balance, put in more than you take out and make sure it gets visibility.

I wouldn't keep someone who is not performing for whatever reason, because by the time I lose trust in that person, in my mind he's pretty much out of the door. Because this is business , it's not a charity , one is responsible for their own life.

As for those who say ' company culture and fairness ' I say your competitors are already eating your lunch

lr4444lr 22 minutes ago 0 replies      
The problem with posts like this is that we only get one side of the story. Bottom line, everyone - up to your top performer - "needs improvement", so the phrase is meaningless. The world isn't static, and if your employees don't demonstrate a reasonable interest in continual improvement, it's a bad sign. If am employee is operating unsatisfactorily now, objective benchmarks and timelines need to be set, not weekly meetings, unless the employee is asking for that level of feedback.

My takeaway from this is that frequent 1 to 1s are a good idea for every single employee, from the day you start to the day you leave the company.

You need to use them for positive feedback as well as negative, and general chats about progress and ideas.

What an interestingly bizarre article.

What we're all missing is how these things were presented - were the managers being unreasonable dicks in the way they talked about

"Mismatched expectations" about availability aside, what does the author expect when they're supposedly letting their team down?

I've had a number of conversations with managers were they've told me I'm letting them down and I'm always incredibly grateful for them. Sure, they're sometimes hard to hear, but I would much rather to receive feedback early so I can act on it and be better at what I do.

Also not to mention how incredibly valuable I find regular peer-review cycles (last 2 companies I've been to do these every 6 months). They've always found it super helpful to be told what I should continue doing well and what I need to improve on. Does everyone want to be the best at what they do?

tiredwired 3 hours ago 1 reply      
It's important to know what parameters they use to determine who or what needs improvement. There have been times when a manager told me there was a problem and it turned out he had inaccurate information. The manager was looking at the wrong version, branch or had 3rd hand information. Managers have claimed to be unaware of what I was working on even with daily standups, task tracking and working a few desks away. Some managers are terrible.
dudul 1 hour ago 0 replies      
I'm not sure what this post is complaining about. Whatever is advocated at the end seems to be exactly what the managers at this company did.

How can the author say that they don't see the point in these plans what it appears that they were able to correct their behavior and stay at the company until it went under?

"By the end, they were quite happy with my work." Looks like the author is building this whole drama out of nothing.

I find that PIPs tend to compensate for bad management in general. By that I mean I know where everyone is on their projects and weekly checkups are a norm, if not more than once. I know a few people who have been on PIP at work, I have don't know how many don't complete it but it does tend to correct their manager as well since HR follows through with insuring that the program is followed. It is a program, HR has a check list of items that must be met each week by both manager and employee. This tends to remove some of the stress on the employee as they do see both sides have to play ball.

that being said there have been a few put on PIP I think would be better separated. I guess from this standpoint it does serve to protect company interest.

I do know that working remote introduces all new problems, the hardest I had to learn was to not let myself be distracted and I actually ended up with a personal check list that became natural after a time. I now understand how to make sure those who get more than one WFH effectively use this privileged and keep it.

Google is releasing 20M bacteria-infected mosquitoes in Fresno techcrunch.com

jimrandomh 16 hours ago 9 replies      
This is called the sterile insect technique, and it is a well-established practice for getting rid of mosquito populations that could threaten humans. It is very safe, both to humans (male mosquitoes don't bite) and ecologically (species other than mosquitoes aren't affected at all).

It sounds like Google is working on improvements to the process. This is important work, because mosquitos are a major cause of disease, especially in Africa, and we haven't been able to fully solve the problem with existing technology.

Keyframe 58 minutes ago 0 replies      
Unlike other questions, I'm interested in logistics behind this. How do you produce 20m mosquitos and where do you hold them? How do you transport them and how do you release them? How do you 'store' them and when releasing are most harmed, are they 'sprayed' or you 'open a box and they will go by themselves'? How do you decide where to release them? Is it all at once (1m per week) or is there a pattern, is it related to wind... so many questions!!

I wan't a documentary "How it's made: Mosquitocide". I'm willing to make one if someone can provide access to info and logistics.

I recall hearing when I was younger that mosquitoes were an outlier in the natural world. With most species, the balance of any food web would be pretty thoroughly disrupted by a major culling. As I heard it, this isn't the case for mosquitoes - if you could press a button and kill them all tomorrow, most ecosystems would be largely unimpacted.

Am I just making this up/misremembering it?

Edit: found a few sources.

Thank goodness. We can't eliminate mosquitoes fast enough.

Wildlife will probably find other food sources, so bring on the weapons of mosquito destruction.

Can someone with knowledge of this particular experiment explain how they've overcome the regulations that have stopped Oxitec / Intrexon with their aedes aegypti solution? They key regulatory factors cited against Oxitec, especially in their Florida Keys trials in the past year, were centered around controlling for the release of only males (which do not bite humans), thus avoiding transmission of any kind from the genetically modified varieties, or bacterially modified varieties in this case.

Oxitec has worked for years to filter their mosquitoes so only ~0.2% of the released mosquitoes are female[1]. They then had to demonstrate that and more in many trials before being allowed to release their mosquitoes in the wild in Panama and Florida.

Otherwise, it's great that Google can overstep the other factors that would stop this solution like NIMBYism and working with county / municipal boards. These solutions are great.

From what is explained so far, this process doesn't kill mosquitoes. It just makes sure that some of the females (that reproduce 5 times in a life of 2 weeks as an adult) get fertilized with unproductive eggs. http://www.denguevirusnet.com/life-cycle-of-aedes-aegypti.ht... The eggs of aedes aegypti can be spread anywhere and the fertile hatch whenever their area gets wet in the next year or so.

Does anyone know what % population reduction impact this process results in? They'd have males likely die after 2 weeks and that just wipes the reproductive chances of the females in that period. Google is treating for 20 weeks in dry weather, which is not exactly the peak reproductive season of this mosquito.

It has a very concise, cross-platform GUI DSL ("inherited" from Rebol) which requires a 1MB runtime only on top of the host OS' GUI system.

Look what can you build in ~7kB which can run on top of a 1MB runtime, not a 100MB browser...

To some in the west, China is a land of opportunities, a booming economy with tech giants and a supply chain for the industrial world. To others it's a bloody dictatorship that assassinated thousands of people for the sole crime of speaking their mind in 1989.

To me it's the embodiment of the hypocrisy of the west when it comes to the defense human rights. Let's be frank, we didn't abolish slavery, we just outsourced it to make it more acceptable. It's also a proof that capitalism doesn't need democracy or free-speech to function.

You ever get the feeling this Nobel Prize and the western media's fawning coverage of Liu Xiaobo is really just about westerners making themselves feel better?

China will get democracy one day. It will be because a large swath of Chinese people want it. Although there have been some high profile dissidents in China over the last 30 years, including Liu Xiaobo and the 1989 students, most Chinese are probably not ready for their message of political openness. They're still focused on lower levels of the Maslow hierarchy like shelter and food.

These dissidents have the bad luck of poor timing. In another 30 or 40 years when China is fully developed, their ideas may be well accepted among citizenry and party reformers.

Hi, I'm one of the founders of Quilt Data (YCW16). We built Quilt to bring package management to data. The goal is to create a community of versioned, reusable building blocks of data, so that analysts can spend more time analyzing and less time finding, cleaning, and organizing data.

Our general inspiration is to create a new kind of data warehouse based on code management practices that haven't yet reached the data domain.

Feedback welcome. Ask me anything.

It's outrageous how little tooling support there is for version control in data compared to code. Every mainstream database forgets history with updates, don't support distributed workflows, don't support commit ids as first class objects, or most other basic features of VCSs. Databases just aren't a solution to version control.

I can't imagine a future where we don't treat data version control like a necessity in the same was as code version control. I hope Quilt can fill the much-needed role of "Github for data".

I think it was a really interesting (and smart) choice to convert to Parquet format. Columnar storage is so much more efficient, and working with data in Parquet is pretty fast using the engines they mention (Apache Spark, Impala, Hive, etc.).

I actually had been thinking about Parquet as a component of ETL, and if it might be possible to make ETL many times faster by compressing to Parquet format on the source and then transmitting to a destination - especially when you're talking about limited bandwidth situations where you need entire data sets moved around in bulk.

This looks really nice for sharing public data sets, but I wish that there was a better public non-profit org running indexes of public data sets.... I guess if something like the semantic web had ever taken off, then the Internet itself would be the index of public data sets, but it seems like that dream is still yet to materialize.

chubot 8 hours ago 3 replies      
This sounds like a promising book. I read the The Idea Factory a few years ago, which is a related and fantastic book about the history of Bell Labs.

Around that time I came across an interesting idea. I don't remember if it was in the Idea Factory, or in material I read afterward, but it's related to one of central ideas from this excerpt:

The sender no longer mattered, the intent no longer mattered, the medium no longer mattered, not even the meaning mattered: A phone conversation, a snatch of Morse telegraphy, a page from a detective novel were all brought under a common code.

The idea I came across is that:

 Shannon's information theory, devised at AT&T, indirectly led to the demise of AT&T's monopoly.
Before Shannon, there was no concept of the information-carrying capacity of a wire. And AT&T's monopoly was largely due to it having the biggest set of wires, which as you can imagine were expensive to deploy in the 19th/20th century. I remember that calling California from NYC was a huge achievement, precisely because of the number of physical wires that had to be connected. AT&T was the first to offer that service.

So I think the argument was that it made economic sense for a single organization to own all the wires, so it could maintain them with a set of common specifications and processes. But if you can reduce every wire to a single number -- its information-carrying capacity -- then this argument goes out the window. You can use all sorts of heterogeneous links made by different manufacturers and maintained by different companies.

(I'm not sure if this is historically accurate, but technically it sounds true.)

So my thought was that there's an analogous breakthrough waiting to happen with respect to cloud computing. Google and Facebook have information monopolies based on centralized processing of big data in custom-built data centers. Likewise, AWS has a strong network effect, and is hard to compete with even if you have billions of dollars to spend.

So my question is: Is it possible there will be a breakthrough in decentralized distributed computing? And could it make obsolete the centralized cloud computing that Google/Facebook/Amazon practice? Just like AT&T had no reason to be a monopoly after Shannon, maybe a technological breakthrough will be the end of Google/Facebook/Amazon.

Maybe this idea is too cute, and you can poke holes in it on a number of fronts, e.g.:

- Shannon's ideas were profound, but they didn't actually bring down AT&T. AT&T was forcibly broken apart, and there are still network effects today that make re-mergers rational.

- Centralized distributed computing will always be more efficient than decentralized distributed computing (?) I'm not aware of any fundamental theorems here but it seems within the realm of possibility. (EDIT: On further reflection, the main difference between centralized and decentralized is trust, so maybe they're not comparable. Decentralized algorithms always do more work because they have to deal with security and conflicting intentions.)

But still I like the idea that merely an idea could end an industry :)

Relatedly, I also recall that Paul Graham argued that there will be more startups because of decreasing transaction costs between companies, or something like that. But it still feels like the computer industry is inherently prone to monopolies, and despite what pg said, the big companies still control as much of the industry that Microsoft did back in the day, or maybe more.

It uses `array` (somewhat mutable Erlang structure) and NOTP (no idea how it makes code "zippy" and the repo [1] does not explain anything... it seems to be bypassing the normal way modules are loaded?).

I am unsure why anyone would use Erlang for number crunching. Training neural nets is basically just multiplying big matrices. I was hoping this project would come up with an interesting approach (how about using SIMD on the binary comprehensions that can use it? now that would be cool) but performance / memory usage does not seem to be looked at here.

It is naive / uneducated to think that "Erlangs multi-core support" + distributedness will enable many things for you. How does the VM scale on 32, 64 threads? Have you tried making a cluster of 50+ VMs? Unfortunately Erlang Solutions Ltd.'s marketing has hyped many.

I am not against projects like these, I am just looking for reasons behind the choices made.

This is a neat idea but it would be great if there was a bit more substance to the post. Do we have any performance benchmarks? Why would I consider it a strong contender? Stating "multi-core support" to me is not necessarily scaling.

I'm in no way an expert, but I work in Erlang in my day job and just glancing at the repo, this solution can't possibly be performant. A) Erlang is slow at math. B) Arrays don't have O(1) access(ETS tables might be able to help with this). C) You can't scale this solution with more Erlang nodes(without some additional work).

I really like Erlang and want to evangelize it but I don't think this is a good way of doing it. I only see this as a neat toy but not a selling point for using Erlang..

As a side note: I noticed the repo has a feature note about adding NIF's for performance bottlenecks (native C code for Erlang to talk to). If you end up writing C code, then what are you gaining from Erlang?

I don't disagree that people aren't getting all the steps they need, but it seems like there's a pattern where hotter areas have less 'activity' (step count).

Central America, Northern South America, Northern Africa, and the Middle East seem particularly bad.

Looking at the "walkability" graph, you see that a lot of the cities listed as the worst (Arlington, Forth Worth, San Antonio) are in Texas, where it's pretty hot.

Living in Las Vegas, I totally get this. You just don't go outside in the day time, which can put a crimp on activity.

On the flip side, in the winter it's very nice, and is the perfect time to go outside and get some exercise.

1. Demographics are not controlled for

2. Temperature variations are not accounted for.

3. "The cost to exercise" (e.g. cost to live in walkable areas, average cost of gyms, etc.) is not accounted for.

Furthermore, the website (haven't read the paper yet) implies walkability is always good. Walking around during the summer time in a hot climate like Texas will get you killed [1]

The analysis is obviously good, however it basically says what's already obvious, rich people exercise more (in the case of United States). Is there something inherent in the areas that make people more or less likely to exercise or is it the demographics? Most of the evidence points to the latter. This raises the question: since you inherently can't change your demographic, what difference does it make?

Anyone interested in this might enjoy reading about Cardinal Giuseppe Mezzofanti[1] and other "hyperpolyglots" in Michael Erard's Babel No More.[2]

An excerpt from the Introduction:

"...Mezofanti liked to quip that he knew 'fifty languages and Bolognese.' During his lifetime, he put enough of those on display -- among them Arabic and Hebrew (biblical and Rabbinic), Chaldean, Coptic, Persian, Turkish, Albanian, Maltese, certainly Latin and Bolognese, but also Spanish, Portuguese, French, German, Dutch, and English, as well as Polish, Hungarian, Chinese, Syrian, Amharic, Hindustani, Gujarati, Basque, and Romanian -- that he frequently appeared in rapturous accounts of visitors to Bologna and Rome. Some compared him to Mithradates, the ancient Persian king who could speak the language of each of the twenty-two territories he governed. The poet Lord Byron, who once lost a multilingual cursing contest with Mezzofanti, called him 'a monster of languages, the Briareus of parts of speech, a walking polyglott, and more, -- who ought to have existed at the time of the Tower of Babel, as universal interpreter.' ...

"On one occasion, Pope Gregory XVI (1765-1846), a friend of Mezzofanti, arranged for dozens of international students to surprise him. When the signal was given, the students knelt before Mezzofanti and then rose quickly, talking to him 'each in his own tongue, with such an abundance of words and such a volubility of tone, that, in the jargon of dialects, it was almost impossible to hear, much less to understand them.' Mezzofanti didn't flinch but 'took them up singly, and replied to each in his own language.' The pope declared the cardinal to be victorious. Mezzofanti could not be bested."

I have had thoughts about how we attach meaning to symbols in computers (our designed computational systems), and how a physical system like a landslide, or accretion disk or something could accidentally assume forms and computation-like behaviours which we could attach symbolic meaning to, yet mostly do not /can not as we are not watching.

With such a vision there is strong ambiguity in the world over what is potentially symbolically meaningful to someone, the meanings things can carry, and the stories their symbols can follow. I think that essential ambiguity of interpretation, of the apparent orders and symbols in the world, makes nonsense of the popular idea that we may ourselves be certain sophisticated symbolic constructs in an advanced simulation.

Sorry for this but I am in the middle of doing something else and have only skimmed this paper but it looks tantalisingly relevant...

It depends on the hash type. Cryptographic hashes (MD4, SHA1, SHA256, etc.) are made to be efficient and fast to compute while password hashes (bcrypt, scrypt, etc.) are much more difficult to compute. The difference is staggering.

Stupid question, but what does this particular password hash unlock?
developer2 16 hours ago 3 replies      
One reason: you'd be surprised how many companies allow entering the hash as an alternative password to login to customers' accounts in production. Lazy method for customer support teams who don't have support tools to access customer information. Also frequently done to allow developers to debug problems on a customer's account when a bug cannot be reproduced elsewhere.

If such a company's database of hashed passwords is leaked, then an attacker doesn't even have to crack the hashes - the hash itself is a valid version of the password. Yet I've seen this behavior at multiple companies; only one of them pushed back against my request to remove that "feature", and I didn't stay with them much longer after that.

Sure, in an ideal world: post the hashes, the salts, the hash algorithm, everything. If it's done "right" (e.g., the hash function has enough complexity), then brute force cracking, rainbow tables, etc. would take so long that it wouldn't be feasible to crack them with any volume.

Of course, you could still crack some (problem), so keeping multiple secrets hidden through obscurity (the hashes, the salts, etc.) is another layer of security.

This doesn't guarantee security, but it's certainly more secure. But it is additive: there's no reason to just use MD5 (or plaintext) because "my hashes are secret".

I was kind of disturbed that GitHub publishes every user's public key.


This is a different situation and public keys are not directly analogous to password hashes: there isn't a reliable way of cracking public keys in the same sense that there's a semi-reliable way of cracking hashes. But it was still strange and uncomfortable to me that they would reveal this "target" (and if there were specific key generation bugs, like RNG seeding errors, people might actually be able to crack a few of them and know that they had suceeded).

Relatedly, I was thinking about the magic crypto-cracking device in the movie Sneakers. Once they had it, they could immediately use it to log on to random network-connected services, defeating the authentication. So, how is that supposed to work? How do they automatically know what credentials would be accepted for a particular service? Are there common network authentication protocols based on public-key cryptography that have the property that the verifier tells the prover the public keys that it trusts?

This doesn't touch the real problem. Nobody intentionally creates a policy that will take $20K from someone with $40K and give it to someone with $10K. When that happens at all it's unintentional (e.g. 20 programs to transfer $1K that weren't expected to overlap) and people who discover that outcome find it outrageous.

Because that was never the problem with income inequality to begin with.

The problem isn't that one person makes $10,000 while another makes $40,000. Those people are both struggling. The problem is that one person makes $10,000 (or $40,000) while another makes $10,000,000.

Reversal never even enters into it. If you took $9,900,000 of the richer person's money and split it between 1000 poorer people, the richer person would still have more money. Even though that would imply a 99% tax rate.

It seems like an alternate explanation is that people don't like to artificially pick winners and losers, but they're willing to lessen the gap between winners and losers if it's too big.

There are philosophical concerns about justice and utility in messing with organic selection mechanisms. Perhaps a fear of instability plays into it, but it seems like there are more nuanced narratives that can be applied as well.

Another way of interpreting the results:

- 76.87% of subjects accepted a 25% tax rate intended for redistribution.

- 44.80% of subjects accepted a 50% tax rate intended for redistribution.

It's hard to infer much beyond that.

Perhaps they need to test for a larger number or more fine-grained tax levels between 25% and 50% and see if there is indeed a step change (or other sharp decline) in acceptability when it "reverses social order". Or if there is a smooth distribution curve based on tax rate, not relative position.


Even if you take the results as intended, that subjects were considering social order and not tax rate, you still have to concede that this could be about "fairness" and not "rank". It shouldn't be surprising that a majority of people dislike redistributing more than is necessary to achieve equality. That helps explain the results with the children. Ages 6-10 is about where they start to understand "fairness" from the perspective of both parties [1].

Additionally, taking the tax perspective into account, "Person B" appears to be subject to a lower tax rate than "Person A" despite ending up with more money, which subjects would likely see as unfair.

Not sure why they draw the conclusion that the aversion is about not wanting to upset the social hierarchy. That's an amorphous statement in any case and carries different connotations.

Seems a more succinct conclusion is that it's about fairness. Most view the economy as a zero-sum game, and we generally measure our standing in society relative to others. So, the idea of redistributing wealth to the point where relative fortunes are being inverted may violate our sense of fairness.

There is a lot to be said for not wanting to piss off the people who control the money that flows to you. I am not as certain that people would choose to keep things the way that they are if they also weren't keenly aware (as say, someone might especially be in China) that the State might be monitoring their answers.

It's also very important to remember that most people who manage wealth well, on the other hand, do so in a way that benefits those who do not, and as such retain their responsibilities as money managers because they are one half of a financially symbiotic system of exchange.

There are also a lot of social factors to consider that didn't necessarily (and understandably so) make it into the studies dependent or independent variable sets. The attractiveness of each party needs to be controlled for, as there is a definite bias to give money to those we find attractive. The age of someone is another control variable that needs to be accounted for, as the elderly are generally (and correctly, generally speaking) more adept at managing money, for how else would they have survived so long?

All in all, I think mostly what this tells us is that we are cautiously optimistic about the belief that those who have less in our social hierarchy are capable enough to have more, but that it's important to preserve and honor the way in which wealth flows because it flows in a way that has kept us progressing for millenia.

I would be much more interested in reading about how much wealth they believed should be distributed rather than simply if it should. That would give us more than a binary response from which to extrapolate data.

Hey Sergio,

Regarding fairings, it seems a missing "middleware" case might be the sorts of things that cause redirects on entry (e.g. redirect routes with/without trailing slashes to the latter as a super trivial example). Is that something you'd expect to support in some way? I think that's something that doesn't feel like it maps either to guards or fairings well at the moment.

I did see where you mentioned your dislike of rails/sinatra/... style blunt force middleware, fwiw.

Would love to have a better article as a starting point for discussion of this book here.

It seems like kairos is like Csikszentmihalyi's flow. It's time that passes while you are engaged, active, purposeful -- living rather than waiting.

Perhaps without a willing participant, there can be no kairos; there is only chronos?

Great book, BTW. The most memorable from my childhood.

Good article. I have to say, after reading it, I still don't understand the difference between chronos and kairos

This book had such a profound influence on my life and young mind. It basically formed a lot of the values I have and ideas about what is right and what is wrong.
