I actually read this before. It's a fun read for anyone who finds the psychology of persuasion and manipulation interesting. It probably helped me save over a thousand dollars on my family's last car purchase. If you just want the "what can I do to avoid getting cheated" summary, use one of the following options:

1. Have an agency buy your car for you. You might not save as much as you could if you really knew what you're doing, but you won't get taken advantage of this way.

2. If you want to do it yourself, call dealerships up on the phone and compare prices. You might have a lower chance of convincing them to sell you the car than if you went in person, but you'll make sure you won't get ripped off.

3. If you really want to go to the dealer in person (I have used this option successfully), do your research. That doesn't just mean knowing the MSRP and the dealer's invoice cost (much lower than the MSRP), but also looking on edmunds.com or elsewhere for the current promotions (called "dealer incentives") that the manufacturer is giving the dealer. You might not be able to find all of their incentives, but you can get close. When you're at the dealer, don't let the salesman express prices in terms of monthly financing. They'll use the four square technique and rip you off with 100% certainty. First agree on a price and then you can talk financing with the F&I guys in the back. To get the price you want, start really low. Offer a number around the invoice cost and be willing to go barely more than $500 over (at least for non-luxury cars). When they tell you that they won't make any profit that way, you tell them about the dealer incentives you know about. If you still meet with resistance, you can even hint that you suspect they have other incentives you aren't even aware about and that you really will leave the store before buying a car for much more than the invoice cost. If they still won't budge, try again at a different dealership. If you have trouble with this method, switch to #1 or #2.
Do you really expect your app to run on all Windows machines flawlessly?

By and large, yes, people expect that and developers largely achieve that. But of course Windows is a much more mature platform than Android.
Yes memory access patterns seem to be the most common bottleneck for most parallel code. I was implementing a parallel version of quick sort recently and I have similar stories to tell.
Optimize the code to avoid cache misses frequently and you end up getting a near optimal speedup.

There is, or used to be, some show on I think the History Channel about how a lot of these processed foods are made. It was fascinating and disgusting in equal measures.

I think the real difference is that in one case you have someone watching a puree of HFCS, artificial thickeners, and almost-real-food slide down an assembly line following directions with little room for personal initiative, and in the other case you have people painstakingly writing code line by line, having to think carefully about each of them. There are a lot of people involved in manufacturing, but there isn't much thought and care compared to individual craftsmanship.
I have a friend who is a teacher, she had to explain to her class that no, they did not have mobile phones during the Great Fire of London, no, not even "bricks". Some of the class didn't believe her.
The idea that redundancy in language is a sign of inefficiency is wrong. In fact it increases efficiency because it makes it less likely to misread or misinterpret something. I don't think you'd actually be increasing your bandwidth, if you remove superfluous letters your eyes won't have to look over them but you won't process the actual information any faster, you've just eliminated additional cues.

While it is possible to make a phonemic alphabet (phonetic would capture people's accents as well, which is probably not what you want), this removes the connection words have with their foreign origins. Plus pronunciation might change and you don't want to rewrite all books whenever that happens. You have to learn reading & writing anyway, so it might as well be a separate language to some extent, so that it can be more stable.
Mmm, that's true. Even if it was just a list of countries, though, I don't think the flight info has to be more detailed than that; you're generally going to be flying into a city anyways, so it's not like knowing that someone likes hiking will help too much. I'd be happy to have someone find me a cheap flight to somewhere-in-south-america-really-I-don't-care-where-or-when.

Mid-Day: There's something about Sulagna Panigrahi
Last Monday, when I caught her between promotional interviews for her new Kahaani, Sulagna Panigrahi was in an advanced state of pregnancy. And like any mum-to-be, admitted to being tense and thrilled about the coming ‘baby’. Any cravings, I prodded, recalling how I’d uncomplainingly walk for an hour-and-a-half when I was expecting my daughter, Ranjika, for a double scoop of ice cream.
Blekko's good for images? I gave it a few tries a while back but I got distracted by the slash syntaxes and forgot what I was looking for :) I'll give it another try.

Disabling JS on Google Search (with Opera's site-specific preference or NoScript) also does a lot of good to make this once-great search engine somewhat more usable (not for the results, of course, but at least it's not continuously stealing input focus and mucking up its own search results as you try to navigate with your browser's keyboard shortcuts).

Help with Android app
Hi all,

Today I read that Ministry for Information Society and Telecommunications of my country (Montenegro) is holding a competition for best Android app.The main goal of this project is to promote our country via Android app (for tourists)

I want to take part in this project but i never been in 'developing Android apps' business.
Deadline is 10. june 2012.
I want to write simple android app, nothing complicated.It would have popular tourist locations of my country, some info and pictures of them, and maybe have the option for pointing those locations on google maps.

1.How do I start?
I googled a lot of tutorials, but I want to ask you if you can recommend me some tutorial(video tutorial would be the best) which describes simple android app development from scratch.

2.What is the best IDE for beginners in Android apps business?I downloaded IntelliJ IDEA, is it ok?

3.I want to start learning today and I am willing to work on developing this app every day for about 2 hours.Will it be enough?

Thanks to anyone reading this and willing to help ;)
Sorry about that. I got too caught up in showing that there was in fact an optimal strategy, and there were no hangman paradoxes. In response to (2), that was done in the GGP -- you are selecting the question that for all words gives you the least distance from the answer (and if that doesn't cover every answer, then the minimal number of questions to do so). I posted ruby code in the GGP for a heuristic version, the non heuristic version would look similar.

What follows is my solution to this game after having a night to sleep on this. It's O(26^26 times words) [because it requires you construct the optimal move for the guesser], so perhaps only of interest to myself.

Problem restatement: Imagine instead that we are playing a game where, for doors 1 through m, we must pick a door and hide some prize behind that door. Our opponent must then choose from a list of moves that open ranges of doors.

To solve that problem, it is relatively easy. First form the set of transitive closures on moves, such that any move that shares a door with another move is in the same closure. Next, for each closure, mark every door by the number of moves that can reach it, and progressively remove the highest marked number until doing so would then leave no doors. If at any point this process led to those moves no longer sharing a closure, reform the closures, add them to the list, and process them again in this manner.

Observe that for any closure remaining, for every pair of doors (a,b) reachable by the same moves, we can discard the second without changing the optimal strategy (because any move the guesser made would be the same to us for both a and b).

Now observe that for any closure remaining, if the dictionary only included words reachable from that closure, picking with a uniform randomness among the doors not removed by counting or pairing would be optimal (as the same number of moves can reach any remaining door). To prove that moves with higher marks would only decrease our EV, simply observe that if we did include any door with more marks, then those moves could be favored by the guesser to increase the guessers chance of winning.

To complete the solution, we work out the the expected value of playing each closure independently, and select between them by the ratio of their inverse EV with the whole. (So if we had two closures, one with EV -1 [if we could only choose from words behind this door we would always loose], and the other with -4/5 [all doors can can be reached by 4 out of the 5 moves in this closure], we would pick between the two with a ratio of 4:5).

For a proof that the above mixing is optimal, see the analysis for the game "Bluff".

Anyone who understood all that, lives in San Fransisco, Santa Barbara, or San Diego, and would like to meet up to discuss economics, game theory, algorithms, machine learning, computer science, or world domination over coffee is cordially invited to email me at dls@lithp.org (yes, that's "lisp with a lisp", perhaps puns should have been on that topic list as well :p)

Last time your project came up, I wanted to ask if you've done any research into the various already existing shorthand writing systems ?

When I tried to find out more about those 10 years ago, a lot of sources were old and hard to find, but with a bit of persistence I found some PDFs and websites on a system called "Gregg Shorthand". Fortunately today it's right there on Wikipedia for you: http://en.wikipedia.org/wiki/Gregg_shorthand

> Machine translation would be almost impeccable.

This is completely wrong. Current machine translation struggles not because languages are hard, but because translation is an inherently hard problem. Humans can only translate reasonably after years of training. Semanticists can only provide a formal logical treatment of very small fragments of language, which indicates that a logical language would be either incomplete or not completely formal.

The bottom line is that translation involves understanding meaning, which involves a lot of interpretation and world knowledge, which is very difficult to put into a computer, whatever the kind of language you're trying to translate.

Compared to this, speech recognition has been relatively successful, so a language with a phonemic alphabet is not very urgent.

An article about the reasons infantry fire or not:

http://www.historynet.com/men-against-fire-how-many-soldiers...

I read somewhere (citation needed!) that the percentage of soldiers who deliberately fire their weapon at the enemy has increased from WWI to the Iraq conflict, which some put down to violence in movies and video games. After watching excellent Iraqi conflict documentaries like Restrepo and Armadillo (Danish movie) and seeing how soldiers react to conflict, there could be merit to that argument.

The nail in the coffin for me on W|A was requiring a login in order to copy plain text results. (Even though the same data is copyable in the DOM, they actually go out of their way to obscure it!)

I don't think people understand how noxious this registration-obession is, especially when you need utilize it to access basic functionality.

I don't really go to W|A anymore unless there's something specifically math or statistics related that I'm looking for. That action killed any kind of casual use for me.
> Let's take an analogy: Your Windows PC runs an OS very similar to the ATM across the street [...] Do you really expect your app to run on all Windows machines flawlessly?

Yes, I do. (With limited exceptions.)

Software often has minimum specs to run. Apart from games the minimum spec will often be for machines that are obsolete.

So (apart from games) I would expect an app created for one machine running MS Windows to work on another machine capable of running the same version of MS Windows. And those versions of Windows will last for several years.

Compare that with Android as applied to cell phones. Not everyone upgrades their phone every 18 months[1].

Now if it'd make international transfers easier... But still, $0.99 is pretty steep IMO.
Is there any delivery pizza in SF that doesn't use low-fat cheese? Every pizza I've ever ordered for delivery in this city does not survive being refrigerated and reheated. I've been told it's because of low-fat cheese. If I go back to visit my parents in MA, get some pizza there, and reheat it, the cheese melts beautifully and tastes divine. But any delivery pizza in SF, when reheated the cheese doesn't even melt, I have to touch it to tell if it's hot, and it tastes terrible.
This reminds me of Elian Script[1]. It is not particularly optimized for reading but
it is extremely easy to learn and become proficient in.

The usual habit to develop ones own handwriting style when using this, makes it something rather unique to each individual. This also improves writing speed because you optimize the letters to suit your own writing style. We both (friend and me) use it as a form of poor-man's-cryptography for diaries and stuff we write in public (trains, buses, etc).

My friend's Elian compared to mine is almost unrecognisable at first glance. But if you understand the few basic rules for the writing system, you can read either of our versions very effectively in only a short amount of time. And those rules are preposterously simple. You do not have to memorize different shapes for each letter of the alphabet. That's a definite plus.

Maybe they can get some publicity and get that area known as the pizza part of town, so they can both raise their prices and win.

Actually why would you think a Windows app wouldn't run on that ATM? I'd bet most would. It's probably a normal PC, with all the normal hardware. It would be slow, because it's most likely a slow one with no GPU acceleration and such, but I wouldn't be surprised if 95%+ of Windows apps ran on it. The only reason you, yourself couldn't test it is because they (obviously) run their own ATM software full screen and block you from installing stuff. But why wouldn't you think an ATM admin couldn't fire up Solitaire on it?
Heck it was never a big deal is factually incorrect.
IT is STILL a big deal:

Fragmentation means your ATI card not working one day, or your novice user having to go dig through pages of support to figure out how to debug a faulty driver.

Or its your printer not working on XP, but working on 7 || your games being unplayable on one set up and working on another without a hiccup || any of a massive set of issues that people take for granted when they have to deal with PCs.

Fragmentation is an issue, its just that people have gotten used to it and familiar with it.

Fragmentation IS a problem and remains that way.

The difference in the two situations of course being the the colour of pizza sauce and subway services is constant, whereas the price of the ticket and the pizza slice are both variable over time.

It suggests that both values are tied to the same index somewhere - for example maybe both the government and pizza places have tied their pricing to be 0.1% of the average monthly wage. Or maybe it's tied to the price of crude oil. Figuring out the common index may give valuable insight into government services pricing and pizza making...

I think it's very valid criticism and it can't really be compared with Windows. There's many differences:

- Windows has a lot of APIs and hardware abstraction levels. Microsoft has always been known to change things very, very slowly, and keep backward compatibility.

- Hardware makers don't mess with Windows nearly as much as they do with Android. They will install a Norton trial and that's it. They don't remove the UI and put their own.

- Microsoft acts as a gate to what innovation hardware vendors can bring in, even more so today with driver testing and signing. Remember back in the day when an OEM did something crazy you'd get BSODs from bad drivers. Now that doesn't happen anymore, because everything is so much more robust. Android is still no where near that, and Google isn't doing much, relying on the open community.
If you are a mobile software developer who refuses to deal with Android under the pretext it is "fragmented", you will simply be obliterated by your competition. The Android market is so large, and becoming larger every day, that other developers will gladly do the work you refuse to do. And they will succeed, just like the desktop/server software development world has learned how to cope with "fragmentation" in the Windows/Linux ecosystem by supporting the various OS versions, editions, service packs, distributions, locales, etc.

It does not matter what you think about Android fragmentation. It exists. Deal with it.
That's the problem with party-driven politics; the limited scope of which issues decide elections. Copyright is never a frontline issue during elections because there are always bigger problems.
