You just get used to whatever units you're working in. If you'd been trained in radians when learning how to fly, everything would be fine. It would be funny though to hear ATC clear someone to land on runway pi/2. That's probably not as succinct as runway 9, but people would be used to it if they learned it in their primary training.

The real problem though is switching costs. There are tens of thousands of planes out there and more than a million pilots. To switch all of the compasses, GPSs, flight computers, heading indicators, etc. as well as retrain a metric pantload of pilots would be ludicrous for no appreciable gain.

Canada suffered through a problem similar to this when it went metric, and ended up with the Gimli Glider. http://en.wikipedia.org/wiki/Gimli_Glider

Don't get me wrong though. I love the metric system and think it's great, however first and foremost we are creatures of practicality. If US dominance in the world slips over the next few generations, I would imagine it will at some point join the rest of the world and abandon imperial measurements.

I will never understand why people think Monte Carlo is such a neat solution. There is nothing random about pi.

Why didn't you just pick the center of the square, use that to partition it into 4 pieces, and recurse for each subsquare?

Or just as easily do this? http://pastebin.com/ezi7S35N (Edit: just noticed a typo -- I should be initializing the numerator/denominator inside the loop, not outside, sorry.)

What's the point of adding randomness?
Definitely not a misconfiguration. I had the exact same issue after a certain period of time with every fresh install. The solution was switching to Prezto / fish (work / home respectively).
With a cold start - yes. But most GPS chips have memory backup for short-term almanac data (valid for up to 4 hours, works if the GPS doesn't move long distances in that time period) and internal clocks, so it can perform a warm start. This takes only a few micro Amps standby current, so it's not hard on the battery.
>>kPa. Otherwise it'd be Kelvinpascals.

Great observation! I guess I am way too used to KB and in that very case KPa would be 1024Pa which is even worse. Have an upvote.
Branding and Positioning
Al Ries recommends to focus. For consumer goods or for yourself, building a brand is essential.

In an overcommunicated society (a marketplace with lots of fresh out developers and talented business analysts), you have to find a place in the prospect's mind (the recruiter). Find the position where you can be Nr 1 (or Nr2). Take a look at Positioning, http://www.amazon.com/Positioning-The-Battle-Your-Mind/dp/0071373586.

The Laws of Branding gives valuable hints on how to build a strong brand. What holds for goods also holds for you and your career. http://www.amazon.com/The-22-Immutable-Laws-Branding/dp/0060007737
It would be interesting to see how quickly a quasi-random, low-discrepancy sequence converges to PI (e.g. a Sobol Sequence).
It's a reference to the 'Chinese Room' thought experiment.

http://en.wikipedia.org/wiki/Chinese_room
0°F is quite a pointless border. Brine freezing? Why would you care about that event to make the scale based on it? Water freezing on the other hand is way more relevant for common matters. So lower border of the 0-100 scale was chosen quite poorly from pragmatic standpoint. And natural temperatures can go above 100°F, so the upper border wasn't chosen conveniently as well. It's not as uncomfortable as Kelvin, but it's still way less pragmatical than Celsius.

I have been privately lumping causation and correlation together for decades now. It freed my thinking. While the two are certainly different, it is also true that causation does not have the set-in-stoneness/invariability that is commonly taken for granted. Witness the recent discussion about nasa's impossible-space-propulsion.

In terms of a human acquiring knowledge, correlation certainly is the first step. It is also called observation. Causation just seems to be a subsequent underpinning with context and concepts.

That is exactly what makes Monte Carlo neat! There is nothing random about pi, yet using randomness we can arrive at pi.
Interesting. Yes I can imagine it being exception after exception. The liable party point is definitely an interesting factor. I guess it would be arranged by contract to flow through to the company providing the automation system or the trucks themselves. Not that the distribution company wouldn't have responsibilities in the event of an accident they would otherwise have figured a way out of, and other new diligence in general.

Whatever system does it, it will have to be able to handle a bunch of wild situations autonomously. After thinking about it I don't think any sort of remote operation can be relied on as a technology to the degree that hypothetical laws would require.

My workplace does run BGP but we don't have the whole table. Is there anywhere I can see something like that "BGP ticker" ? Is that channel on a publicly-available IRC network?
We don't necessarily have to use randomness. We can take equally-spaced points in the quarter as well, rather than sampling. This is called pseudo-Monte Carlo.
Calling it "pseudo-Monte Carlo" is like calling a landline phone a "wired cell phone". It kind of misses the point.
Nice work. I did a very similar simulation a year ago when I learned about MC in the context of particle filtering in a course about recursive estimation at ETH.

Why not, indeed. The question is whether that would be a bad thing. It could serve as a great signal to those companies that they shouldn't send you any email.

Oh I definitely think any sort of time spent stationary by a truck full of goods is a security concern. The places you mention are obviously the safest in the world but there are certainly people who will rob (burglarize?) trucks if given the right opportunity.

This reminds me of an anecdote from a local (European) telco:

A customer called the customer support line because their monthly invoice was way higher than in the previous months. They had 3G data access modems/SIMs and a fairly standard contract. The CSR searched their record and found that they had a lot of roaming data fees (really expensive if you don't have a special contract). The customer then replied "I see. Well, we use these data SIMs in special collars to monitor some bears... One of them went abroad."
ls | py -x '"mv %s %s.txt" % (x,x)' | sh has me worried, I can't find the escape code directly. Also you might wish to offer the following api ls | py -X '["mv","%s","%s.txt"] and run those using processes or sub-process. This would ensure the right argument in the right place. Just an idea.

I lived through the change in ZN a long time ago - really only two comments to make:

- for most things a saw cut is ~1mm wide - measuring in mm is good enough for most things, it's a great unit for carpentry

- a 2x4 (or 4x2 anywhere other than the US) isn't really 2x4, but then neither is a 5x10 (the exact same thing after you go metric)

Using equally spaced points doesn't produce an unbiased estimator, while a monte carlo simulation does.
Well, in the first place I cannot. I take the thing as it is. This is the risk-taking part. But, I guess, that is why I have to move from correlation to causation or rather embed this one correlation into a broader context. Because it protects me against correlational flukes.

Thanks for this inspiring question.
IMO, this is a great deck for IBM (better than many of the tech presentations by companies pitching for enterprise business):

(a) Showing interesting non-proprietary technology, which everyone can play with;

(b) Well thought out demos, which even point out limitations, and work-arounds (xyz views for the game);

(c) the 'IBM takeaway' that actually points out the corporate use-cases obliquely, without ramming that pitch into everyone's face at the start.
MAC because this sort of logging is the responsibility of MAC frsmeworks.

Integrity control is not MAC. It appeases a few problems but misses the point.

It is very slow. Two orders of magnitude slower than syslogng. When there is forwarding back pressure it just shits itself. It's awfully designed from end to end.

No, you missed the point. In problems with a very large sample space, quasi-MC methods are invaluable. They converge faster and can be shown to approximately have the benefits of traditional MC methods.
I personally feel that the removal of developer tools as a standard component of the OS has been one of the biggest setbacks for computing - especially teaching computing - in the last few decades.

I can understand the commercial reasons - "developers! developers!" monkey-dances not-withstanding - and I can understand the 'consideration of the average user' not needing the tools installed, but I don't agree with it.

I think that any OS that doesn't ship with the tools required to make that computer do more work is a crippled, none-OS, and I urge my fellow geeks to disassociate themselves from the elite mode of thought that states that developer tools should only be available for developers. So much serious advance of the state of the art has occurred just because there have been compilers on board when a curious mind first logs on ..

I'm immensely saddened to hear of my younger siblings first experience 'with computers' being the panopticon of the iPad. No compiler onboard means its not a computer for you, but rather the person who made it, and this is really frustrating to see younger generations getting conned out of some really powerful features of their lives. Just the hassle of having to sign up to get the devtools is enough to dissuade the curious, and its precisely the curious we need to invite to this party.

"Their early work was a little too new wave for my tastes, but when Sports came out in '83, I think they really came into their own, commercially and artistically.

He's been compared to Elvis Costello, but I think Huey has a far much more bitter, cynical sense of humor."
I think we're talking past each other here. Talking about "sample space" inherently assumes you're dealing with a random process. My point is pi isn't random, so coming up with a random process just so you can force MC on it and then suddenly deciding you want to make it deterministic just so you can call it "pseudo-MC" is kinda... weird, to say the least.

I really wish people would stop trying to find ways of calling their algorithms "Monte Carlo" just to make their work sound fancy. All it really achieves is it makes them avoid thinking about how to solve the problem. Monte Carlo isn't a universal hammer. First you're supposed to show randomness actually helps you gain something, then you're supposed to start using it.
Oh the trolling one could do with this. I believe this has great great potential. Nice work.

It would be key to figure out a way to capture (not avoid) the hilarious aspect that people will use it as a joke. That's what I love about it.
If you're told there's a resource emergency, and you need to conserve / stop doing things you like, but you look around and see just profligate usage of that resource, it's pretty natural for your response to be, "Bullshit." eg Ruby Hills in Pleasanton (a gated community with enormous bright green lawns), or agriculture. Hell, even in Wisconsin -- which has few water issues -- agriculture doesn't water all damn day long because so much of it evaporates. We do in CA.
The simulation actually follows a binomial distribution, meaning the standard deviation can be calculated as sqrt(npq), where n is the number of trials, p is the probability of success (pi/4), and q is 1-p.
For a simulation of 10.000 iterations, the standard deviation is approximately 41. You say you observed 3.135 after 10.000 iterations, meaning you observed about 7837 hits. The expectation was to observe 7854 hits, meaning there was only a difference of 17 hits - well within 1 standard deviation.

edit: naturally you can also use this information to calculate the number of trials needed get a desired probability that the estimation falls within certain bounds from pi.

Because you're objectifying a person?
Who cares? The error is going to be there either way. And Monte Carlo can't guarantee any hard bound on that error, whereas using equally spaced points gives you a pretty darn good hard bound.
The issue is that most drivers incorrectly assume they are in the weakest position for any given scenario. They absorb delays as if it were their own fault and falsify logs to compensate. Many drivers even absorbed the reimbursable toll costs on a route because they couldn't match the ticket times to their falsified logs.

They are afraid to log as 'on duty not driving', which is how they legally should be doing it. Sure, they make less that one day but the sheer number of hours wasted at the shipper or consignee will have a knock-on effect which will make on-time delivery less likely. I drove tractor-trailers in the US for eight years and I would tell other drivers 'this system is broken, allow it to fail and cover your ass by documenting everything'.

I refused to falsify my logs and would rigidly log everything 100% accurately, even logging Hours of Service violations (e.g. difficulty finding parking & going 30-45 min over on drive time) which could have cost me a ticket. Once in a while I'd get hauled into a weigh station for an inspection and they'd notice the hours violation. I explained about refusing to falsify and they'd see this was true. I'd get a funny look but never a ticket.

The outcome here was that I was very predictable to the 'trip planners', who were one grade above the lowly dispatchers. The trip planners always knew exactly where I stood from the truck's telemetry data, plus I would always communicate delays. They were better able to predict how to use my time and their company truck. I was never out of pocket for reimbursable expenses because time/date stamps on receipts always matched. I was making more than most of our company-employed drivers and even some of the owner-operators who struggled with fuel costs, etc.

The dispatchers hated me because they constantly had to explain to management why my loads were late and how I could not be blamed for the delays as I had documented everything and communicated the delays well in advance. Every other driver would have gone over their hours illegally to compensate, but I always stopped when I ran out of driving hours and therefore missed appointments.

They all caught on after a while and learned to use my time more wisely. I reliably made $50-55K/year which was exceptional for trucking and enjoyed the very low tax rate Hours of Service workers get (9%, taking the standard deduction x days worked, typically). It was an interesting job overall because of all the sights you see, but I can't recommend it to anyone looking for a career change. Stick with the tech sector as it is much safer and you can go home every night.

The example applicative still respects sequencing - to do what the last paragraph claims to be doing you'd need to use some kind of nondeterministic gather.

Honestly I think the differences in that example are pretty superficial. The real advantage of applicative is that because the assumptions are weaker, some things that aren't Monads are Applicatives.

> "... if you read the EULA ... and keep track of updates, you have the power to turn the relevant permissions on and off as you see fit."

Translated into the real world that is full of people who are neither lawyers or software security experts: "You better have the time to dig through a bunch of incomprehensible legalese and try to find someone who can explain the jargon if you ever hope to keep any privacy."

> "a surveillance device that’s recording your every move 24–7 and constantly reporting back to the mothership is complete and utter nonsense."

This is only "nonsense" if you fail to comprehend hyperbole.

Spying doesn't have to be 24-7 to be damaging, and many things can be batched. A good example would be aggregating usage statistics of something every time the app starts. No 24-7 required to crudely emulate rrdtool, e.g. inferring someone's schedule from when they use various features can be very powerful.

Also, this makes the usual error of assuming that once the permissions are opened up, they won't change (intentionally or otherwise). I seriously doubt the author reads ever version of every EULA before installing updates. Normal users don't have the time or ability to keep up.

> "If anyone’s spying on you, it’s probably your mom."

translation: "Too many people have built business models that rely on acting antisocially. People might stop using those services if they knew how they really worked, so stop talking about how they are trying to create a surveillance state!"

I'm sure Facebook's definition of "spying" is just as creative as the NSA's definition of "collection"; it's the same style of lying with word games.
Good point regarding setting up for double/triple word scores, however I doubt there is much soul reading or bluffing in scrabble - I think the cost of making a sub-optimal move is too great, you'd need to be very sure that it hurt your opponent even more than yourself.

Also although the remaining letters are known, your selection is random. I don't know how you could possibly choose between words to maximize your next move when you don't know what letters you will get?

Interesting point made in article is that lot of enterprise customers are not upgrading to WIndows 8 because they have strong dependency on IE8.

Microsoft just scratched off a year of support for IE7, four years for IE8 and IE9, and seven years for IE10. After Jan. 12, 2016, the only current browser -- Microsoft is sure to release others before then -- that will retain support on the dominant versions of Windows will be IE11.
I think there is some value to this method, but it may not be readily apparent in the present context. If you have a problem that you don't yet have a firm theoretical handle on you can figure out a baseline value for the answer using this technique, and then work backwards to give you the formula that allows you to arrive at the real answer.

I use that trick a lot, for instance with Euler problem 307 I could not find the answer easily in an analytical way, did the simulation, found an approximate answer (to within 6 decimal places or so), used that to figure out what I was doing wrong and then computed the real answer.

Some may see that as cheating, but it works wonders and not just on that particular problem.
