Run Goldy, Run New highly addictive game with 10% proceeds going to charity
Hey guys, I want to invite you to check out my new game, Run Goldy, Run! It's basically a 2D sidescroller based on dodging a never ending onslaught of enemies, with the twist of being able to run on the top or the bottom of the floor. It sounds confusing, but it's completely intuitive once you get into it. There's two basic controls, FLIP and SHOOT, blending the simplicity of games like Flappy Bird with the insane difficulty of...also Flappy Bird. It tells the simple story of a sheep with golden fleece who was born to run, and the eternal swarm of enemies who will stop at nothing to claim his precious pelt. Anyway, it's my first major game release and I'd really like to invite all of you to check it out on the AppStore or my website, goldythesheep.com.

Given that it's my first real project and I have little to no experiencing designing games, I'm not anticipating to make a huge wad of cash off of it. However, 10% of whatever I do make off of content ads will be donated to charity, specifically Children's Hospital in Dallas. I'm a guy who likes to play games, and I made a game that I hope you will enjoy playing, but if that doesn't grab you, you can also help the disadvantaged. That's right, you can play an awesome game, support a budding indie studio, and help the poor, all at the same time!

So again, try it out, let me know what you think, and if you enjoy, please share. Have a good run!

>I don't think there should be any argument there

I'll argue against that point. I don't live in a system where I can trust that helping the police won't be turned around on me because they're just looking for somebody to pin charges on or because of bullshit laws that shouldn't be a law to begin with.

I have assisted the police exactly one time, when I witnessed a kidnapping, but I had to be extremely cautious because my roommate was a marijuana smoker before the state I lived in at the time had legalized it, and he had his stupid paraphernalia all over the apartment. The cops wanted to come in to ask me questions but I couldn't let them in the house because I didn't know what shit was lying around, so I had to make up a ridiculous excuse to do the entire questioning outside on flimsy lawnchairs in the yard. I was put into the position of trying to decide if I should risk fucking over my friend or not report a kidnapping.
A Day in the Life of a Stolen Healthcare Record
But the question is how the population size relates to health, which you haven't answered here. You have numbers for the number of deleterious mutations, but that doesn't directly give a quantitative relationship between population size and health.
For example, you say,

> If the suspect is a better match than N(1-p) of the other fingerprints, then the match has a p-value of p.

There may be no way to objectively determine if the suspect's prints are a better match than others.

More generally, I lack your expertise but it seems to me that statistics require data; we may not have reliable data. More colloquially, garbage in, garbage out.

Anyway, I recommend the National Academy of Sciences report, which is authored in part by their Committee on Applied and Theoretical Statistics.
One thing you're missing is that 25,000 of the FAA employees are Air Traffic Controllers. There is no equivalent function that NHTSA does that would require that many employees.

This whole comparison grated on me. Either the NHTSA guy is an idiot or Gladwell is an idiot or both, likely both. Or they're deliberately prevaricating and hoping that most people won't notice. I can't stand sloppy "factoids" like that. Context is essential.

I'm surprised that hadn't been tried before.

I'm also curious how software plays into it. Is the computer and software basically just a glorified on/off switch, or is it doing something more intelligent than just blowing air?
As it came up in the discussion at Reddit (http://www.reddit.com/r/haskell/comments/3425pk/refinement_t...), there at least exists "data-checked" (http://hackage.haskell.org/package/data-checked).
For those interested in these kinds of issues, I recommend the Reference Manual on Scientific Evidence, written by the National Academies of Science for federal judges.

Just the chapter "How Science Works" by David Goodstein, Professor of Physics Emeritus (and former Vice Provost) at Cal Tech, is a revelation for anyone outside the scientific community. Highly recommended.
Interesting article. It seems to me like what you really want here is to do this in a lisp/scheme. Then you can use the full power of lisp (it's the exact same syntax as the behavior tree), leverage lisp's built-in control flow constructs, and just implement nodes as functions with side-effects that return either true, false, or null or something.

Unless you think that investigative journalism has a strong interest for Sudden Acceleration, the take-away here is that they have a strong interest in scandal and stories that sell newspapers/airtime/whatever. The US government conspiring to protect the domestic auto market is exactly the kind of scandal that sells newspapers.
Using the Template Haskell bits have all the disadvantages of Template Haskell - mostly a slower compile. Other than that, I don't see many downsides. As mentioned in the discussion on r/haskell, things get a little tricky when your arguments interact, but if you're okay with uncurrying you can still verify that you've got a sane combination: http://www.reddit.com/r/haskell/comments/3425pk/refinement_t...

It also may require some explicit conversions in places they shouldn't strictly be necessary.

Other than that, I don't see any downsides. There do seem to be a couple similar libraries, but feel free to start using it everywhere :)
I think "Proof by cases" uses proof by contradiction. You're proving that given A -> C and !A -> C, then C, which requires the axiom A v !A, i.e. proof by contradiction. In your proof, you've proven k=0 -> X != 2, and k > 0 -> X !=2, but it doesn't follow that X != 2 without contradiction.
That's easy to say when the products you sell aren't as easy to pirate as movies and music.

Let's say a content provider created the perfect media service, exactly to your specifications - super easy, DRM free, etc. etc. Done and done; the service issue is gone.

Tomorrow, you want a new movie. On one hand, you have Provider X's new service, and on the other, you have piracy, which gives you pretty much the same content it always has but now is relatively less convenient in comparison to the service. Which are you going to choose? Oh yeah, by the way, piracy is still free, but Provider X is charging $19.99 for a movie, because that content service cost them millions. More importantly, they don't want to devalue their content. They don't want to live in a world where the street value of a first-run film is 99 cents.

Piracy is a value issue. The only reason it looks like a service issue is because there's a reasonable solution to that part of the problem and it's easy to point at content providers and blame them for not fixing it. But the reason they don't is because if they did, it would simply surface the other side of the problem, which they're not going to do anything about.

Personally I think the first half of the article was fantastic, then it tapered off toward the end. But ultimately, my takeaway is that we should be more considerate in all aspects of our lives about how our actions affect others, which is a good resolution, even if the moral of the article was a bit muddled by the end.

You know, that's a very bold statement for someone who probably is not and never has been a physics educator. In order to make any sense out of even entry level physics and in some sense understand how it's unified, we teach (an often light) version of Newtonian mechanics; it's really rather strange, and usually far too abstract to teach Newtonian mechanics without simple forces like gravity near the surface of the earth. I also beg to differ about gravity, as it does play a role, albeit may not as large, when looking at things like kinetics of the body.

If you want to see someone who does an exceptionally good job teaching physics to the non-hard sciences, Brian Jones at Colorado State is kind of renowned in physics education circles as being one of the most effective in being able to convey lots of good meaningful entry level physics to soft sciences and pre-med.

I am confused by the links you follow up with. The first is a _rejected_ false-flag operation against American civilians, the second is CIA action overseas. The Gulf of Tonkin incident saw ... no American casualties.

And you use these as some kind of proof that the idea of the US government knowingly killing 3,000 of its own citizens, causing massive economic damage to the US, isn't absurd?!

What, the first one, which never happened, or the second one which wasn't a false-flag incident against the American people, or the third one which involved no American casualties?

I've had my own bad experience with forensic science.

I was a research intern at Oak Ridge National Lab. They put on several educational events for the interns. One event was a guy from the group doing forensic science to come in and talk about it. He talked about rate of decay of corpses and things like that.

Then he brought out dowsing sticks. Said something about the bones of buried bodies giving off magnetic fields that affect the sticks.

He then took a leg bone out of a trash bag, put it on the ground, and walked passed it holding the sticks. The sticks moved when he did it, but of course when anyone else in the room tried nothing happened.

Honestly, all the interns in the room were dead quiet. I think we were all really confused, thinking that maybe it was some sort of joke or hazing. Or maybe a test of some sort? It was really weird, but destroyed my regard for forensic "science".
There is another factor to consider. Future scientific gains may be more expensive to obtain than they were in the past. For example pushing the frontiers of space exploration is going to require much more funding. We have a few rovers on Mars now, but to get rovers on Titan will not be as cheap as getting them to Mars.
Why would I do that? They don't lose anything and I get to put pressure on the producers to get their heads out of the sand.
It's not just the money. You also have the bad impression that this leaves in the minds of their guests, who feel like they're being ripped off.

In my mind, it's similar to movie theaters charging upwards of $5 for a coke. I understand that movie theaters can charge what they want, but someone, somewhere has decided that the maximum profit is attained by these very high prices.

But, look around the movie theater - relatively few people bought a coke. 90% of the audience are sitting thirsty for 2 hours.

My suggestion is. Charge $2.25 for a coke. Publicize it, so that people know that you're the theater that doesn't rip people off.

Being that theaters are always complaining that they make most of their money on concessions, you'd think that they'd want to differentiate themselves on the value they bring, rather than just fleecing their customers.
Too much wear and tear on the brush, it would last about 100 yards before you had to replace it.
It was the best source at hand, if you have another study i'd be interested to hear it.

There's apparently 2.9bn internet users, so you're right that ~5% isn't a very big number in context.

Mmmm... We'll just have to disagree on this. I can track a great number of octaves, from business strategy down to operating system scheduling and locking strategies, CPU instruction pipelines and scheduling, semiconductor fabrication techniques, and even down to the lifetime exergy of the whole equipment/software/facilities supply chain. But I can only do a little bit at a time, an as-needed basis. I can't be too concerned with instruction set design or supply chains while I'm optimizing an SQL query or building a D3.js web visualization. It's just too remote from the task at hand. If you, in contrast, can simultaneously understand and reason about every technology along the continuum from delivered apps and services down to the impedance constraints in the CPU layout process, good show! That's a surpassingly rare skill, but perhaps there are some Sherlocks among us.

You raise some interesting points.

As I said, jq is impressive. It is a JSON processor that implements it's own functional language, complete with variables, function definitions, arithmetic, recursion. There is no question that it is useful and will be the absolutely right tool for a number of jobs.

Likewise with awk. I really, really like awk. It is such an elegant solution to a common problem (text parsing and productions). It is also a functional language.

XSLT is also a functional language. An XSLT processor is expected to implement a standard (as opposed to jq and awk) - but that's a minor difference.

It is when you are required to blend the disciplines that the limitations sneak up on you. In powershell it works the same regardless of whether I process data from JSON, from XML, from line-oriented text, from CSV, fixed columns or or from database queries. Sorting, grouping, comparing, mapping, presenting, converting - it is the same skill set.

That is not so say that something like PowerShell can or should replace tools like awk, XSLT or jq. It should not. Period.

But for tasks where one has to use several formats, the lack of a sufficiently strong inter-command protocol causes the tools to bloat and include functionality that has nothing to do with the core task. Consider, for example, why jq needs a "@csv" function (called a "format string") - and @html, @sh, @base64!

My claim is that those functions have nothing to do with JSON processing.

The equivalent in PowerShell is handled by ConvertTo-Csv, ConvertTo-Html, Out-String or the [Convert] class.

It really comes down to a n*m problem. jq is just one tool that implements csv or html formatting (m formats). There are n tools (jq, awk, xslt, ...). Should they all use the same rationale as jq and implement csv formatting? Or should they stay away from that and just concentrate on the core task.

In PowerShell the equivalent of jq - the ConvertFrom-Json cmdlet - just converts from JSON. Regardless of whether the objects were converted from JSON, line-oriented text, database queries, fixed columns, XML - the output formatting is handled by tools that are optimized for that.

If I'm dissing anything it is the limited inter-command protocol of traditional shells. In this day and age we process complicated structures that are not easily expressed in line-oriented plain text.
I like this idea of distributing the load, but what about a phone app that was able to use the sensors on your phone. I would think there would be some way of using the iPhone's internal sensors for this purpose, and pushed via an app store, I think it would reach more people. IDK...
Indeed. My memory is failing me but I seem to recall having heard or read someone talking about the brain and stating that its sole purpose is to move the body. Thus, an organism that does not move does not need a brain, and as a proof of this idea he mentioned that some animals, like some medusa, loose their brain once they fix themselves to the floor (turning into polyps in the case of medusa).
I like OSv, just because it doesn't have TTYs.
Box office earnings are a barometer for home market sales...in fact I'd go so far as to say that the theatrical release is, for most films, the advertising campaign. Most films lose money at the box office but that's OK, because the purpose is to establish the perception of the film in the public's mind as A Movie, so that it can make an actual profit in the secondary market.

Merchandising and other ancillary income is nice but doesn't amount to much for non-blockbuster films. Your R-rated drama isn't going to make tons of money from novelizations, t-shirt and poster sales, even if it's a hit...maybe 2-3% of your budget. Some films have lots of marketing/product placement potential (or are put together specifically to meet that requirement) but most don't. seeing a major reliance on that in a film's business plan would be a huge red flag.
If your Redis died, you must have to saved the sent messages to process later. It's the most important fact about distributed message queue.
How much is the Frozen franchise worth in terms of merchandise? Much more than the tickets, no doubt.

There are pros and cons, however I think this course has its place. It is for people who know they are good at their degree, but are looking for a challenge rather than easily coasting. In this respect I think it is fantastic.

The other side is that it is brutally hard, consumes a lot of time, and leads to a lot of dropouts from the course.

It is purely an elective course. Everyone who does it knows what they are getting in to, and then come out the other end knowing they've passed the test and recommending the course to everyone else. Given that it is one of the most highly praised computing courses at UNSW (along with Security and Algorithms), it must be doing a lot right

Note this is just based off friends experiences. I have never done this course as the timing was never right

>On the other hand, any school can spin up a law program and start charging admission, no matter how qualified it is to actually do that.

And a lot of them did, because a successful law school is a license to print money. Tuition is high, and there are no pesky labs or expensive test equipment to maintain.
One explanation for the inconceivability is that earlier runners weren't "milers". The milers of Fletcher's era were amateur athletes with well paying professional jobs suitable for an Englishman with bording school and university education.

The pool of gentlemen runners was small and not motivated by money. They didn't welcome competition from all comers...e.g. Jim Thorpe was stripped of his golds for playing semipro baseball and Jesse Owens had to live off campus at OSU. Access to sports competition was a privilege in the first half of the 20th century.
I'm guessing you didn't have much success. Everyone thinks they'll be on the right side.
You strike on a significant point that most HN types have no idea about: the majority of most big schools that do any research (state schools, big private schools like Ivies) get the majority of their budget from taking a cut of research grants, and secondarily from state funding and tuitions. At the various schools I have been involved in different forms with, tuition covers on;y like 20-40% of operating costs; the people who were really keeping the university afloat were researchers _not instructors_. It is partially because of these huge monetary incentives that STEM professors are usually expected to be researchers (and administrators of grad students) first, and teachers second: they have to pay the bills.

"software that detects when the locomotive is slipping, and automatically activates ARC to clean the rail."

Modern heavy-duty Diesel-electric locomotives know exactly how much traction they have at each wheel, and are constantly adjusting the drive power, frequency, and phase for the AC motor in each wheelset to keep all the wheels in sync. The locomotive controller has the info needed to turn the blower on when needed. So that's the software component.

This works a lot like a sander. Locomotives have been dumping sand on the rails ahead of the driving wheels when extra traction is needed for the last century. Doing this with air has advantages - you can't run out of air, it's a better way to get rid of water and leaves, and you don't get sand-choked tracks.
Also consider that people in those days had little choice but to work physically hard, and so if any were super athletes it would become apparent.

Today, super athletes are drawn from highly motivated people who choose it. That is a far smaller pool of people, and may not necessarily correlate with people who have a genetic predisposition to being a super athlete.

For example, someone with the right super athlete genes may never know it because all he does is sit around writing compilers.
