No other prime is divisible by (1-sqrt(-5)) than (1-sqrt(-5)) itself, and yet you can multiply other numbers together and get a number divisible by (1-sqrt(-5)), namely 2 and 3 to get 6.

I think the problem I have with fizzbuzz sorts of code 'challenges' is that it shouldn't be about if you got the right answer but more of how you go about finding the right answer; getting requirements, understanding the requirements, and coming up with something close to those requirements even if it's wrong. Instead, I've seen from other people's anecdotes is it's more treated as a standardized test for aptitude and it's just a bad approach to treat them as such. All the binary right/wrong approach proves is that some people aren't quick thinkers or they're bad test takers. In my own brief experience of a few years in programming professionally, the real world is rarely about binary right/wrong and more like iterative less wrong in terms of developing applications. The latter approach requires the ability to self-correct, seek solutions from others when you're lacking knowledge, and knowing when to tell your superiors that something contradicts earlier, mandatory, requirements of an application. So, I don't blame people pushing back against the HR-woo that's creeping into IT. Simply put, if a company thinks programming is like reciting all the capital cities of the United States and Territories then they have no clue what programming is about and maybe they should get out of that business altogether.

Helicopters and planes exist in relatively small numbers, and their movements are often modified to reduce the impact of their noise.

A nitpick: almost all fixed-wing airplane noise comes from the engines, not the downward movement of air. Listen to a glider and a light powered airplane of similar mass for a good illustration. Helicopter noise is more complex.
Ask HN: On giving up?
Hi,

I am a full-time programmer and don't have a degree in CS. I intend to learn Scheme and have been working my way using this book https://www.amazon.com/Concrete-Abstractions-Introduction-Computer-Science/dp/0534952119.

I had a aim to solve all exercises so it was going well until I got stuck in one of the exercises in Chapter 7. I found it non-trivial and though I let the problem cook in the back of my head for more than a month but I couldn't solve it.

Now this is effecting me because a)- I am feeling like giving up on this book, because I wanted to solve all exercises and now it seems I cannot b)- after this book I planned to finish SICP but now I think if I cannot solve this one may be I cannot finish SICP as well c)- and I am also beginning to doubt my abilities as a programmer.

So I need help from people who learned Scheme (using this book or SICP or at MIT) or who are master of their arts---is it okay if you're unable to solve few problems in the book? Should I carry on and finish the book?

Part of me says I should carry on and finish whatever exercises I can solve but it's sort of discouraging that I am unable to solve a problem after a decent industry experience :(
I read your rant and while I agree, you said that classes are not objects in Java. But last time I checked, there was a java.lang.Class object (and objects have a getClass() method which return a Class).
I find it interesting that they only had to replace three capacitors in one power supply. Don't electrolytic capacitors (the most commonly used type) have a limited lifespan because of electrolyte evaporation? Naively, I would have expected that every single capacitor in the system would need to be replaced.
Ask HN: Quirky Ad Theory+Text (Job/Team Recruiting Applications)
Been experimenting with the following job posting ad on Craigslist Las Vegas+Toronto over the last few weeks and have received some amazing replies+resumes. I have a few theories why it works so well, and the types of people that get filtered through the process. Does anyone have any tips on how I/we might improve on it?

Please feel free to use it to run experiments and test things out, but I kindly ask that anyone share data with others to help us all learn something. Thanks!

--

Theory 1: Filters out people with good communication skills, and since these are my own questions, if I like reading the replies, then I should consider that accordingly.

Theory 2: Brings out leaders, and provides more details about potential, vs past experience.

Couple others but those are ones that I keep repeating in my head and thinking: "wow, this person/reply is amazing, and s/he might not have never applied to our company if we framed the conversation differently".

If the response to contract issues like this is "but that's a known failure mode, don't do that", then that signals a problem with the language, not just the contract code.

It also signals a problem with the culture, with respect to the perceived amount of rigor required by the problem domain.
The situation is not ideal. But the consensus among browser makers is that the previously-relevant standards bodies move too slowly. They can implement new transport features independently (like Chrome did with SPDY and QUIC). But the downside is that fragmentation is more likely, as most browsers implemented SPDY's features in HTTP/2 but only Opera has added QUIC.

> What I object to is the instant dismissal of every Gruber article by people who can't see nuance but only black and white. It's simply not true that he is as partisan and in-the-tank for Apple as many people here think he is.

Sounds fair enough, but yet it still seems reasonable to mistrust Gruber's opinions on the basis of him having established a pattern of supporting Apple. The fact that he doesn't literally always come to their defense isn't really all that much of a mitigating factor, since his editorial integrity is already suspect.

> Making assumptions about people's biases is exactly my objection about the reflex reaction many HN commenters have toward Gruber.

I make decisions based on available information. Your post came across as derisive and snarky.
A World without IOT
Conferences usually have way more than three speakers, and the context is clearly talking about actual real-world conferences, where indeed the lineup is often 100% male. And they're implying that this typically happens because they're the most qualified.

Agreed that this is ridiculous. This is a pretty mild bit of satire, but a ton of people here are going out of their way to be offended by it. It's a great example of how many men are completely oblivious to the advantages they receive.

Which makes faster detection a huge deal - I'd imagine one of the conclusions drawn from the results will be how best to detect ASAP without putting sensors literally everywhere.
I should have assumed, given the results that PARC had, that it must have been that way. It's fantastic that I just got the answer to that question from... you.

For my second point -- I definitely didn't mean optimization that way. I guess the word I meant to use was "targeted", as in "targeted for multi-core" but I see your point and respect it fully.

I'm thrilled and deeply, deeply honored to have had this time with you, Dr. Kay. Thank you so much again.

When I read this, I can't think of anything else but Scala fatigue. As a CTO migrating a company from .NET to the JVM, I found there's already a mess of conforming to a subset of Scala within real (and more importantly - ordinary) teams.

What subset of Scala? what libraries? what build system? apparently if things worked well, there would be at just one true - and well respected - answer for these.

So now I ask, honestly, why not go with Kotlin (https://kotlinlang.org/)? a language that IMHO didn't try to rule the world from day one (a Good Thing), but scores high on aesthetics, abstraction, power, IDE, compilation speed, and Java integration.

I have been following (and playing with) Scala since a bit before the Yammer thing exploded, I've been following Odersky as a student listening to the OOPSLA podcasts, and I never got to convince myself Scala is worth it. Can someone convince me to still use Scala when Kotlin is around?

A Brief Introduction to Artificial Intelligence for Normal People
I'm actually finding some pretty good new tracks, I wish I had not to subscribe to get the full Go catalog though!
Great points, and mostly agree.
1. as far as I know, the jack takes up quite a bit of volume, it's a long and empty space, that could be used for battery, heatsink etc. It's a minor save, but smartphones are some of the most volume-dependent devices, and marginal benefits can be high. i.e. most users may swing around say 4 hours of screen on-time, and get frustrated with 3.8h of capacity. Small increases can push them over the contentness-edge. I'm very much reaching here, it's not a very compelling argument imo, but there's some benefit there nonetheless.

2. So apparently I'm the edge case who never charges while listening, it's just not a thing for me. I charge once, at night, and it's fine. (Galaxy S7). In a car I'm happy with my phone's speakers or a wireless setup, and in newer cars especially a usb-audio or bluetooth audio setup shouldn't be a problem. (ignoring obvious transition issues). And especially here, in a private, safe, storage area like a car is, I'm okay (obviously not thrilled) to buy and one-time mount a $25 dongle. Not the end of the world for me. Same with my fixed office space, and that's about all big usecases I can think of.

3. Completely agree, however it must be noted that stuff like this pushes wireless audio quality forward. There's suddenly a forced market demand when the port drops, which opens up industry incentives to push wireless price/performance ratio improvements which I feel are around the corner (and partially announced already). And tech wise a lot more is possible than the quality we've had in the past years. And price wise, a LOT more should be possible than the past few years of price points. Also I'm expecting Apple (let's not forget, a producer of custom earbuds for years, and buyer of Beats) to drop decent wireless tech, too. I want good wireless audio tech regardless of whether I'm forced to use it lacking a port or not. (!) Again, obvious transition issues but it's alright.

4. Rumours are hey're looking to reinvent their base model with oled screens, no home button, edge to edge screen, delayed to 2017. i.e. a move away from a phone that has ports and buttons, towards a device that's completely digital, mostly screen and almost fully wireless. And I think that makes a lot of sense, stylistically too, if rumours are true and they can pull it off. That can reinvigorate sales, because let's be fair, the iPhone 6 was 'good enough', kind of like the Nexus 5 (still a lovely phone I'd happily use) was for the mid-section, the 6 was at the top-end of the market. I've got lots of friends with a 6 who just don't care for iterations. Something radical is needed to get them to buy, and dropping this port long-term as part of the 10y iPhone anniversary update is part of that narrative. Lots of speculation here of course, just thinking out loud to try and discuss your questions.

So what metric do you think is more optimal for deciding how to sort languages from "must try" to "meh", other than actually using the language in production? (Obviously, in an ideal world with infinite time, that would definitely be my choice)

While I agree that the nature and value of reviews is highly determined by things not inherent to the quality of the language (which is to be expected for anything that deals with the real-world), I do think reviews of nascent languages have significantly higher signal to noise ratio than they do for languages that are at their peak or heading towards legacy land:

1. New languages are rarely used by novice programmers. Which means that they are rarely written about by novice programmers. Doing a search for "state of Ruby/Node" requires a lot of work to find reviews authored by experienced developers who have a clear mindset (i.e not just personifying a shallow version of Bjarne Stroustrup's famous axiom), while filtering out everyone who just got out of coding bootcamp and has a good Medium presence.

2. The fact that a language is new means that nearly everyone, except for the creator and early dogfooders, is new to it, which means they come to it with roughly the same perspective (and needs and wants) as anyone who is curious to jump in. Moreover, they are often wont to compare the new language with whatever language they've been using, which helps as a metric for gauging the experience level and judgment of the reviewer.

Sure, there's the problem of early adopters not wanting to shit on a language before it is stable...on the other hand, the kind of people who like to try out languages before they hit saturation are generally opinionated and will make critiques as way to help influence the language, so it's not a total whitewash.

Speaking for myself, reviews are not my first metric for judging a new language or framework. Understanding why it was created and how it is currently doing in production is by far the most important thing to me. Even though React felt very strange to me and many others at first, I still gave it the benefit of the doubt knowing that it was being used in Instagram and Facebook.
This does not mean that arsenate does not get into the bacteria, he points out. “It just shows that this bacterium has evolved to extract phosphate under almost all circumstances.”

Yes, it really wants phosphorus. But, a strong preference does not create phosphorus when there is none to be found.

Not that single cells really want or try etc, but you get the idea.
You're approaching this with a hostile attitude, which is preventing you from understanding and/or addressing what other people are saying, and substituting (light) mockery for attempts to understand what others are saying. You're not going to learn anything or convince anybody of anything this way.

The point of using the ring with the sqrt in it is to conveniently demonstrate that the FTA is non-obvious. Since it is only being used for demonstration, and not as part of a proof, faking ignorance of sqrts and imaginary numbers is not helpful to you. There are many things in mathematics where the subtleties only came out later; heck, that's basically the entire history of set theory. Sets are also trivial if you come at them with an attitude of artificial ignorance like that.
Ya. It's absolute silliness. Rushing in these complicated solutions just to avoid some half-baked slippery slope argument about the block size. You don't need to keep raising the block size forever, just do it until you have a good, clean solution to the scaling problem.

For developers who want to put their apps in the official App Store, this doesn't really help anything. It's definitely interesting, but only on an academic level.

On the whole, the iOS ecosystem is pretty locked down. If you submit an app to the App Store, and there's some bit of code that Apple doesn't like, they can and will reject your submission. You can only have an app in the App Store if you play by the rules.
And I don't get 30% of the articles on HN. I didn't know what a H1B was. Or a 'Series A' round. At one stage I was baffled by the talk of something called 'Bitcoin'.

I sometimes rage about a post title that uses an acronym I've never heard of but it's hard to get the balance right between patronising your audience and mystifying them. My hunch is that a fair proportion of HN are web devs or closely enough linked with web development that they could make sense of the majority of that article.

It has been interesting to see the reaction to this from different parts of the Internet. Some people are absolutely convinced it must have military or intelligence use and their stated cause is bullcrap. They think it's about as believable as harvesting manganese nodules[1] from the ocean floor.

Meanwhile HN commentators are sure this is a brilliant move that will catapult them ahead of the world in deep sea exploration.

I don't know about subway specifics, but the matter was settled a long time ago for buildings - and it didn't take long to arrive at the conclusion. Containment is the policy. The first thing that happens when any toxic substance is suspected, in a security conscious facility, is the shutdown of HVAC followed by the restriction of uncontrolled movement (elevators sent home, security posted in stairwell, etc). Even in areas equipped with filtration systems (like mail rooms). I've never heard anyone suggest dilution, you'd have to have NBC sensors that can instantly detect every toxic substance in order to avoid unknowingly spreading anthrax piggybacked on an irritant like CS. Such sensors do not exist.
That absolutely sounds like a good starting point. Any more info?
Sure I didn't buy it, was just perplexed by the idea itself. I never seen anything so wacky on TV before.

My parents dismissed it right away and told me not to spend time watching that kind of rubbish. I doubt adults believed it, only those who'd fancy paranormal stuff. (All those UFOs, Bermuda triangle, fortune tellers were so ever popular in USSR those days).
Flying cars can generate flying car crashes which seem inherently dangerous. A drone is nothing more than a flying car without a driver. If it breaks down and kills the passenger (and anyone unlucky beneath) who is responsible?
Substantive != primary. Investigation and synthesis are what I mean.

For more substantive comment, for anyone with such a comment, many blogs and fora are readily available. Finding such things may not always be easy (my startup is intended to help with people finding content on the Internet)

If there is value in finding such things, there is clearly a degradation of value in their obscuration. Until the general populace can navigate and find their way to the new sources of substantive content, the internet is effectively degraded in this regard.
