"we (people in general) commonly misinterpret displays of confidence as a sign of competence... This is consistent with the finding that leaderless groups have a natural tendency to elect self-centered, overconfident and narcissistic individuals as leaders"

I would pay for ... Hacker News. The value of journalism is so often negative (with writers removing facts from the original scientific paper and adding a deceptive title), the only real value in my online parkour is a hundred comments from Hackers News. Ten of them will add facts, dozens will bring various point of views for/against the essay, one will really put the story into perspective.

I wouldn't know how to monetize HN without disturbing the savvy balance of profiles and the quality of comments, but to this day HN is the one journalism work that adds value to my life.

Could someone elaborate on the intent schematic that was used to plan the attack? I have always wondered how big military operations were developed, it's hard to imagine anything of that size and complexity in the civilian world.
A highly optimized pedaling plan might even include a coasting section with a strong focus on breathing after the initial aerobic acceleration but before the final effort. If your vehicle is slick enough you might only lose 0.5 to 1 mph but if you can trade that for flushing all the CO2 out of your system, that might be worth it.
I'd say I'm jealous of your space, but mileage is really a problem with that thing. My little Prius gets an average of 50 mpg (30 in the city, 60 on the highway), which makes traveling a much cheaper endeavor.

At the time it was built, it was a little bit noisier than the 707. The only issue is that while planes got much quieter (as the 707 was retired for example and new ones appeared), Concorde kept on flying...

So in a way, it got louder with age.

Because, in the embedded world, you better have a good fucking explanation of why you are using dynamically allocated memory.

Bring a formal proof that you won't go out of memory. Attach additional information on how you wrote an allocator that runs in constant time and does not risk taking it's sweet time to scan a huge area of memory. Sure, it's all O(n), but who cares if determining when you are going to hit the huge n case is equivalent to solving the halting problem.

Of course, at this point, the hassle simply means you don't use dynamic memory.

> The Cultural Revolution kicked off an era of double digit GDP growth in China, which persists to today.

That's, I suppose, chronologically possible. That is, the growth kicked off after the Cultural Revolution.

Note well the word "after". The Cultural Revolution ran for 10 years (1966-1976), per Wikipedia, and then later, after that, China kicked off an era of double digit GDP growth, which persisted in China until maybe a year ago. That "later, after that" part is part of what makes me really skeptical of your view that it triggered the GDP growth.

It seems much more reasonable to suppose that the trigger was Deng's reforms.

> incompetence is overlooked in areas where we expect one gender to have better skills.

I agree and that's a good point. However, 1) if leadership is a male field then men should face higher standards, not lower ones; and 2) the consequences for high-level leaders can be much more serious than tires or nappies, too serious to dismiss with casual gender stereotypes.
Yep, it is a problem (though not on the ocean flight obviously). I'm pretty sure Boeing would have liked to sell a SST given what they spent back in the day and their teaming with NASA to figure out a way to reduce the sonic boom. http://www.nasa.gov/aero/centers_tackle_sonic_boom.html

Are they incompetent, or do they just have different success criteria? In theory, managers are supposed to be dedicated to advancing the interests of the shareholders, and a board of directors supervises their managerial activity. But an individual manager may be much more interested in maximizing his own wealth, and may occupy a job only for as long as he can make a lot of money without getting into trouble, moving on to another firm as soon as he sees that his tenure is unsustainable (but before everyone else has worked out that he's a liability). I mean, why work hard at managing a widget factory if you can more profitably devote your time to learning about doohickeys and playing golf with the owners of the doohickey factory across town?

While I agree with the author's contention that businesses are bad at hiring managers and so reward pathological candidates, I disagree with his assumption that they're merely incompetent as opposed to self-serving. There's also the question of whether corporate boards are always aligned with the interests of shareholders. I know of one small-cap firm that brought in a new CEO who began alienating everyone in sight almost immediately, and whose previous appointments had generated a small forest of red flags, which would have been very obvious to the board. Not long after the new broom arrived the share price fell, the firm was de-listed...and the former founder-CEO sold his shares at a loss, lost his seat on the board, and the firm's IP and book of business were transferred for a song to another firm owned by other directors. (Writing it this way it sounds wildly illegal but my impression was that the activity fell into the unethical-but-legal grey area. Of course I am leaving out a lot of ancillary details, not least to avoid slandering anyone.)

GC allows advanced immutable data structures to "just work." So that's one use-case. They are always very complicated linked structures that would be a pain to manage manually. Immutable programming is all about making many, many, many short-lived objects, and modern GCs are great at handling those.

I really wonder how they could even do fly pasts at air shows.

The only technical reason (technical not economical) Concorde doesn't fly anymore is because the type certificate, aka the airworthiness of the aircraft, was surrendered by Airbus, hence grounding all the fleet and making it unlawful to fly it.

So to fly it, they would need that to be reinstated.

For the Avro Vulcan, they went through a different aerospace company for that.

I'd love to be wrong, but I doubt Airbus would let anyone fly one of its Concorde...

The algorithms work on an input representation, and contain various cases to be considered, terminating conditions, and outputs produced in the appropriate areas of the paper.
Announcing CodeCop 1.1.0 with Fluent API
First off, the title is horribly clickbaity.

Second, we've been getting a lot of links on HN lately where someone blurts out some thoughts on a complex subject and is done in less than a page, with no depth at all. I really don't care for them. They may be short, but the insight density is far lower than that of a real article, so they end up being a worse way to spend my time.

Third, I disagree that programming literacy needs to be taught to everyone. The OP does not bother to provide any specific reason, but let's consider two.

One reason may be for the sake of future employment opportunities. The argument is ridiculous on the face of it, but it's one you see politicians make. It should be obvious that we are not going to need everyone to be a professional programmer. It should also be obvious that the trend is of programming skills becoming _less_ necessary for jobs involving computers, and not more. This trend has been largely driven by UI improvements in the past, but AI is poised to give it a second boost.

Another reason could be for the sake of developing a more rational mindset, or some other skills or attitudes that are beneficial for citizens in general. This is an argument I would take more seriously, but I still have to counter that there are more urgently and universally needed things. Basic numeracy is the obvious one, and in particular statistics. Logic is another.

Programming may be a way to exercise these skills, but it is not necessarily the best way to acquire them. I would argue that people find success in programming because of their existing knack for logical reasoning, rather than gaining it because they decided to go into programming. And if you've ever tried to interview professional programmers for a job, you'd know how many of them can make a living in this field without having developed the problem solving skills you'd like to see.

In fact, focusing on programming per se as a skill to acquire may well (read: would definitely, in the American school system) lead to reducing focus on the basic reasoning skills that are more universally useful, in favor of learning how to cobble an app or a website together.

Finally, it is very dubious that the population at large would be able to learn how to program at a reasonable level. You may say that people used to say the same about literacy, which is now universal; but if you look at it more carefully, you'll notice that a non-negligible amount of people never reaches the level of reading and writing skills you would expect from an adult, and even more people see those skills decay once they leave school.

I'm curious how this was funded. If the authors had asked most anyone involved in Airline reservation management they would have told them this plain and simple as it is no secret. Yield management and airline network dynamics are just some of the drivers for these "common sense violations".

Also just to correct another comment on how often fares change. For international flights airlines can publish new fares to ATPCO up to 10 times per day however with newer pricing strategies/technologies such as bid-price the fares can change to meet the demand curve in near realtime.

Airline pricing and revenue management is a very complex and interesting topic that has always pushed the envelope of technology and business management. There is a reason why google purchased ITA. I was really excited to see a paper on the topic post on HN but in the end this study has very little substance to add to the many bodies of work out there.

> I absolutely prefer strict typing myself. The issue becomes whether or not one thinks type coercion should be a thing.

As a strong typing fanatic, I'd rather have the interpreter/compiler scream at me. In my opinion automatic type coercion is slightly less wrong than undefined behavior in C.

(Aside, did you know that if GCC spots a statically provable null pointer deference, it will insert __builtin_trap() after the deference? I didn't know either until yesterday. This is acceptable because undefined behavior can mean "eat you hard drive".)

If for strings '+' is concatenation, and '*' is for replication with '-' and "/" as exception behavior I can fully understand. (Admittedly '+' over '&' is either style or hard-core "the operation is different, therefore we need a different symbol choice").

Your example worries me. Personally I would not design a language like that.

(Though I may have abused it in the past.)
And if those people flew international business/first, they'd be a lot more comfortable and it would likely be cheaper than an SST. The Concorde specifically was actually rather cramped. Certainly compared to today's seats up front in a widebody but even compared to first class seats of the time.For me, an 8-12 hour flight is a bit boring but, honestly, it's not really uncomfortable if you fly business and that's the relevant comparison to an SST.
How would your method subtract "lo" from "Hello" and leave "Hel" instead of "He"? It gets complicated enough that I think you'd be re-implementing a more limited version of regex.

Also I was speaking in context of Javascript so I fail to see how this applies.
Even better, +"5" will coerce the string to an integer. I'm ashamed to admit that I've abused it.

There is also quite some lies "optimism" in the EU regarding stated mpg L/100km from the manufacturer and real world measured mpg.

The author contends that businesses hire "self-centered, overconfident and narcissistic" managers. Whether that covers for incomptentence or for intentionally harming the business seems an orthogonal question.

I generally think your points are good, but I'm not sure they address this article.
All three are great projects! As @jrochkind1 pointed out, the key difference is that OpenSeadragon is oriented around non-map imagery whereas both Leaflet and OpenLayers are focused on maps. This leads to a number of subtle (and not-so-subtle) differences.

One key point is that OpenSeadragon allows you to set the zoom level precisely where you want it without rounding to the nearest tile level. Leaflet is getting this feature (they call it fractional zoom) in 1.0, but it's not released yet and it's been missing for a long time. If you are presenting a painting, for instance, and you want the contents to fill the available space on the page, this feature is essential.

Probably the biggest difference (as far as I'm aware) is that OpenSeadragon allows you to lay out and animate hundreds of high-resolution images in the same zoomable scene. For some examples of that in action, see:

The wealthy paying for expensive electric cars (I'm sure you're insinuating Tesla) are subsidizing the build out of charging infrastructure as well as a manufacturing base for electric vehicles and batteries.

Those tax benefits the wealthy receive are a less risky subsidy than directly giving electric vehicle and charging infrastructure companies funds directly. Its a balance between doing nothing and doing something more drastic (full disclaimer: we aren't doing enough, and we should be pouring buckets of money into electrification of mobility, but that's an argument for another thread).

With regards to gas taxes, most people already aren't paying their fair share of gas/road taxes (the US highway trust fund is completely broke). I'm not sure electric vehicles are contributing to the problem as much as the existing 253 million internal combustion vehicles already on the road (not counting heavy trucks, that contribute even more to road damage).

>Admittedly '+' over '&' is either style or hard-core "the operation is different, therefore we need a different symbol choice

The former more than the latter. The operation is different therefore we need a different symbol choice - and & also makes as much sense stylistically as + does.

"string1" and "string2", when read, makes sense. & is different from the conditional && like piping | is different from the conditional or ||
