I am the developer of the game (StefanoM). I'm glad people are enjoying the game, and I'm sorry for the downtime -- I did not expect it to become this popular.

If you have any improvements or suggestions (especially on the programming side!), please email me directly.

Update: As an astronomer (and not a professional programmer), being on HN makes me super proud. Thank you!
Good catch. I did not expect the game to become this popular, so I took what I considered to be an easy shortcut.

This is the difference between theory and practice.

Yes, if A and B walk into court and say that the verbal contract exists, it is enforceable. But in the common case, A will deny that the contract existed (or disagree on the terms) AMD without any evidence, the contract is lost.

Now if there is evidence (both sides had taken specific actions obviously in accordance with the verbal contrac, that they otherwise would have no reason to do), ther might be a case. But really, without evidence, the abstract rule will not connecg to concrete instances. Get evidence for everything.
How do you propose companies like Google purchase data centers to index the content of the internet so you can search it? Or offer everyone free storage and anti-spam processing for their emails? Or would your vision of the internet not include services like that?
Ah but in practice, they won't agree. One aide will be motivated to claim the oral contract did not exist.

Sure, so the author's advice boils down to:

(1) If your child does something good,

DO tell them that they are showing traits of a person who does good things (praise character).

DON'T let them think that they're merely a person who did a good thing (praise behavior).

(2) If your child does something bad,

DON'T tell them that they are showing traits of a person who does bad things (shame).

DO tell them that they did a bad thing (guilt).

The situation is vaguely reminiscent of that old social psychology favorite, "fundamental attribution error", which is about how when other people do bad things, we blame internal traits, but when we do bad things, we blame external factors.
I have to agree, Elizabeth is fantastic. Super nice, easy going, and clearly very intelligent :)

It supports user defined 'channels', which are iirc the software abstraction used to do IPC. Multiple 'channels' across a single physical link when going off-chip (akin to multiple tcp connections across a single physical link, but like 'go' the channels will work using memory as long as you're on the local chip) so what that would require is a driver for the links using GPIO pins on the Rasberry Pi. There are a whole pile of HDLC implementations to choose from that you could use for that or you could roll your own.

The question then is how to distribute the code across the links to the other nodes, the transputer runtime would do that for you back in the day.

Likely there will be a ton of hacking involved before you get to the stage where a transputer dev-kit was out-of-the-box 3 decades ago but this feels like it is within the realm of the possible.

I have no illusions that there would be a ready-to-run package available right now that would give you all that, clearly some assembly is required.

So excited to see Loomio on the frontpage of Hacker News! I've long dreamed of an effective web app for consensus decision making processes (and even thought about building one) but as a user of Loomio for over a year I can say they've done almost everything right -- even down to having some serious design chops. I'm so excited to see where they will be able to take this with the money they've raised (hit your goal today! woot!) and look forward to introducing more activist organizations, especially those with people in many geographical locations, to Loomio. Great job to all the devs and designers and alpha and beta testers!

For those of you who don't know, consensus decision making is not just a willy-nilly free for all. Over the years it has been refined by groups, it has developed strong points of process that help ensure it actually is a decision making process, not just a discussion that goes in circles or goes nowhere. (including the infamous hand signals that many saw during Occupy). If you are interested in consensus decision making, I highly recommend checking out this classic book.

http://consensus.net/pdf/consensus.pdf

While I don't think formal consensus decision making is the best tool for non-hierarchical decision making i all circumstances, I do think it is quite powerful /when used correctly/. Historically this has required strong facilitation skills and other roles (timekeeper, temperature checker, etc) -- all of which play their part in keeping the process working as designed.

Loomio has created a platform for decentralized non-hierarchical decision making that bakes in some crucial features /to accomplish formal consensus decision making/. All the activists I know that have tried it have been impressed by the dev team's responsiveness and dogfooding (Loomio uses Loomio), and have found the features enable formal consensus decision making in a way that a discussion board or voting polls or similar tools that aren't quite designed for consensus just don't.
The only significant benefit over traditional operating systems/network services is it's designed to work on flaky hardware and networks. The only use cases i've found for decentralized distributed networks of application services (other than obscure stuff like parallel processing of large datasets) is when you have no guarantees of availability. As far as "scaling", you don't need coreOS to build a scalable network (and i've seen no performance benchmarks of coreOS running on thousands of machines at a time, so I have no idea how well it scales)

No Real Men arguments here. I did not claim testing isn't necessary. I just wanted to challenge the blatantly religious attitude of pretending or believing that a particular form of testing (one with clearly written tests the poster above me would actually read) is all there is and that you cannot review code otherwise. You definitely can, and must.

As far as I am concerned, all techniques that help improve code are welcome and even necessary. This includes testing, manual review, static analysis, etc.
Hi Shivetya,

Admittedly, the point system could have been better designed. However, for this first attempt, I could not come up with a better alternative. "Exploiting" the point system within the game is not that easy, so the people that achieved the high-scores must have played tens, if not hundreds or more, of games before finding the right timing and initial condition.

Those are all imaginary internet points anyway :)
I mean, from my POV as a consumer a Kindle book that I can carry around with me is much closer to a physical book than one of your flip books (which appear to require an active internet connection in order to work?)

The single most important thing I do to "achieve laser focus and concentration" is to work in such a way that I don't need "laser focus and concentration" to get my work done.

This has to be done the night before.

I always quit all online work at least 2 hours before bedtime and print whatever I'm working on.

Then I go into any other room with program listings, blank paper, and pens (especially red!) and plan out all of tomorrow's work.

All analysis, design, and refactoring must be done at this time. I do not allow myself to sleep until the next day's work is laid out. I also do not allow myself to get back onto the computer. The idea is to have a clear "vision" of what I am going to accomplish the next day. The clearer the better.

This does 2 things. First, I think about it all night (maybe even dream about it). Second, I can't wait to get started the next day.

I always wake up and start programming immediately. Once I get going, it's easy to keep going. Any difficulties are probably because I didn't plan well enough the night before.

Yup! And that system need not have two hundred features and formats for the author to learn and master. I've been stoked by the idea for quite sometime.

I remember getting excited about the Atari Transputer [1] in my 520ST days - later on I was lucky enough to do a unit on Occam running on a real T800 - way back in 1992.
They could have based an entire semester on the concepts INMOS introduced with that little processor.

> What does a 18khz square wave look like wher recorded and reproduced in 44.1 kHz.

It looks like an 18khz sine wave, possibly with slightly reduced amplitude depending on the anti-aliasing filter rolloff and fc, but not enough to be audible (18khz isn't audible for a large portion of the population anyway).

> How is phase affecte?.

Probably delayed a bit by the anti-aliasing filter.

> Phase of an audio signal reaching the ears helps you perceive distance and position.

Not at 18khz, the wavelength is too short for your ears to notice any realistic group delay. High frequency localization is most done by ILD and effects caused by ear shape.

> What is the quantization error difference between 16 and 24.

Quantization error in a DAC just defines the noise floor. 16 and 24bit DACs are usually within a few dB of each other in dynamic range, it's really not audible.

> And if the author can't hear the difference between 4bit audio and 12bit audio I question what he/she is listening on. The aliasing would be HUGE.

What does aliasing have to do with bit depth?
I think it is a great product, but the numbers are a little misleading. In microscopy the most important number is usually the resolution not the magnification, and 1µm is what you expect from a 20x objective. The 2100x specification doesn't help much and confuses people, but to be fair, a good 20x objective starts in the $200-400 range.
... wow, the media firestorm around heartbleed was so fixated on the server-side issue that this completely slipped by me. I guess it's only relevant to one particular Android version and a handful of Linux-based versions where patching is expected to occur automatically and quickly, and nobody cares about desktop Linux.
It's not exactly a mental strategy but earphones just loud enough to block out the surrounding sounds with music that I know totally by heart (and without vocals) seems to be the best way for me.

That's kinda what leanpub.com does, isn't it?
The article didn't mention anything about it being a single-use device. And from the description, it sounds like the intention is that the device would be printed professionally for best results, but assembled by anyone (hence the focus in simple instructions that don't require any test).

Also, the article mentions projection capabilities, but as a non-standard modification.
This is a good breakdown, but to address sharemywin's question:

When you tell your child "don't be a cheater," the focus is on character. You don't want them to do things that a person with bad character does.

When your child cheats, on the other hand, you say, "I'm disappointed, because I know you have a good character, but your action didn't reflect that." So, the focus is on the bad action, rather than the character.

Is some of this mere semantics? Possibly. If a person who does bad things can be a person of good character, and a person who does bad things can be a person of bad character, then how do we tell the difference between a person of good character and a person of bad character except by their actions?

But, if we're merely talking about what strategy is effective, then we can indeed say to focus on character when praising and on the action when admonishing.
The (Unintentional) Amazon Guide to Dealing Drugs
When I was in university I had a serious problem with concentration and being "in-and-out" of the zone. So for two years I made an effort to have something chewing in my mouth(started with candies, then pen, and after a couple of unfortunate blasting incidents-coffee stirring rods) whenever I was 'in the zone' or about to be.

After a while, I've been conditioned to be "in the zone" on cue by chewing on a coffee stirring rod. it works about 50~70% of the time, and I have to be not tired at all. It's good to have it invoked on cue, though. I find drinking coffee in general not helping; caffeine is great in getting hufed up for a short duration, but I try not to consume more than two cups a week.

Addendum: A sad side-effect was that now I cannot seem to have meals without being mentally engaged - be it reading or conversing.
Music actually takes me out of the zone. I find getting a small victory early keeps me motivated to keep going.
At the last year's IFA (http://b2b.ifa-berlin.com/en/Home.html) there was a demonstration of a 24-bit audio player with corresponding high quality audio files and headphones. The results, even though it was a single test, were very good. Of course the issue is, the whole chain has to be 24-bit, if you're going to pump your 128kbps MP3 there the difference is probably negligible (not to mention the 1-bit DACs commonly used, that's one of the elephants in the room)

About the MP3 files, yes, the difference is audible. But of course you need good headphones.
Interesting, I had gotten the impression Twitter was aligning itself more with DataSift in recent years. I used Gnip a few years ago and thought it was a great service, although the high price point drove us to ultimately roll our own.
Owning a book is doable online as well. Clone, provide it to the user who bought it.

I'm actually still digging this one but "active internet" connection - yes - that's again doable. Localstorage() /something probably? Or wait for a future to be more online.
I definitely took a shortcut there. I'm not a professional programmer, and any time I dedicate to this I tend to consider as "stealing" my attention from my actual job as an astrophysicist...

I'll do a bit of testing and see what I can come up with.
Implying of course that the "other" talent, you know, not the top kind, you can employ and own all you want?
Pretty sure thats frowned upon. They are paying you for ypur time at the office to work for them.

Plenty of people have done it, but likely not acceptable from an HR perspective.
This is exactly why the 2100x spec is a bad one. The 1µm resolution they claim is no where near as good as the resolution in the linked 2000x images here.
It's pretty easy for absolutely terrible decisions to be made at a smaller startup, especially when you don't have the tools handy to prove that they're terrible decisions.

I happen to work at a smallish eCommerce startup with lower traffic volumes and a 5% (checkout–not engagement) conversion rate, and while A/B testing small (or even large) changes to our homepage haven't proven fruitful, two small changes to our product pages have made a meaningful difference to our bottom line. (And I mean small as in I spent maybe an hour total setting up those tests while on an Optimizely free plan.)

So yeah, I'm an Optimizely and A/B test fan.
Agreed. And adding to that, you have the general mindset of people telling their young adult offspring that they're "fortunate" to find a "good job" and they should, therefore, suck it up and live with whatever kind of injustice is forced upon them. All for that paycheck.
You can also MITM outgoing SSL connections and use heartbleed on them. The vulnerability is accessible before the certificate checks are completed, so the standard MITM prevention measures don't help you there.
Keep in mind you're asking for advice on staying focused on a forum that many people visit to avoid doing their work...

That said, I like https://www.rescuetime.com/ which tracks time spent on distracting vs productive tasks. It's hardly perfect, but it helps "keep me honest" to know I can run a report to see exactly how much time I spend reading junk online instead of working.
Woosh. Yes, that is what I had meant. Thanks for correcting that.
2 suggestion.
1) Make the new game not a full page refresh.
2) Remove the first planet.
That equation is so wrong.

filesize(192kHz + 24bit) = 6 * filesize(48kHz + 16bit)

It also only applies directly to raw audio like pcm. Once you encode it (to, say, flac) some of that size increase could disappear depending on the waveform.

I don't know how mp3 is defined for higher dynamic range, but I know frequency range/sampling rate doesn't matter, because a 128kbps mp3 is 128kbps whether the frequency cutoff is 14kHz or 20kHz. Isn't a 192kbps mp3 from a 16/48 master the same size as a 192kbps mp3 from a 24/192 master?
A new way of visual communication. Thoughts?
If 100% all components of government behave rationally, it doesn't neccessarily mean that the government behaves rationally.

A collection of rational actors may, as a whole, behave irrationally - as defined as 'against their own best interest'. Tragedy of the commons is but one example.

Organized systems may easily have structures that create irrational and destructive behavior, and those structures can be stable enough so that for each separate employee attempting to change the system would be risky, disadvantageous and irrational.
Congrats to those guys. I worked with their service for about a year and they had a great product.
We're pretty far off topic now, but this benefit has been overstated. In most of the U.S. -- the areas not discussed in this article -- cheap housing is the norm. If you have, say, a $150k mortgage at 5% for 30 years, then your yearly interest is going to be less than $5k. That's less than the standard deduction.
Do you have a better method for accounting for the externality of restricting that land to your private use and accounting for your local externalities?

(This is not a rhetorical question.)
Part of the problem here is that it is very hard to audit something OpenSSL's size. It has 450,000 lines of code. Are you going to skim, let alone audit, a mathematics-heavy codebase of that size? No.

Some of that is OpenSSL's fault, but a lot of it is inherent in implementing a 200-page (before extensions!) standard. GnuTLS is 170 KLOC, CyaSSL is 205 KLOC, and even PolarSSL, commonly thought of as the gold standard in trimming the fat, is 55 KLOC.

If you want to reduce the level of paranoia, you would have to pair down the size and scope of TLS by an order of magnitude. For the record, I support that kind of thing, but you would have to cut a lot of things people actually use, not to mention breaking backwards compatibility.
This. I've held essentially both of those jobs at 100-500 person startups and it was hard not to travel. My problems were that it was usually to destinations I didn't care about and that I'd end up working 10-12+ hours a day on-site. But it's easy to just not fly home for the weekend and stay where you are instead. Or fly somewhere else for the weekend rather than flying home.

I have one friend that sold her house and only lives on the road or with friends or family.

All this isn't about MP3, but FLAC which is lossless, so even for the compressed version the same ratios should approximately hold.
