What I'd like to see is a plot of the number of chords used in a song versus time. Possibly even broken down by genre, or correlated to other qualities (sex of singer) et cetera.

If you start at the 1950s, you'll see very simple rock songs; your classic three-chord rock songs. As you hit the 1960s you'll see more complexity; The Beatles, for instance, had more harmonic complexity than what had come before, which continues to be imitated into the 1970s. Then what happens? I don't know, by the 1980s you're looking at a lot of very simple music again, though music is becoming more diverse genre-wise so you're probably getting a larger spread. Then by the present day you have a disturbing trend of one-chord or even no-chord music; apart from rap [which contains no singing but seems to have got simpler even in the backing tracks over the years] we now find that even sung songs are completely lacking in harmony or chord progression. A particularly annoying example I noticed the other day would be that song (dunno who it's by) with the lyrics "We found love in a hopeless place", which seems to have a melody of just four notes.

I could continue this discussion going backwards in time from the 1950s and talking about how the ever-growing harmonic sophistication of art music through Beethoven to Wagner eventually led to a complete breakdown of the idea of harmony in art music which led to music that nobody liked which led to the death of art music and the establishment of rock and roll from square one, but that's another discussion.

Reason: It's easier to play these chords on a 6 string guitar, which has been the dominant instrument of choice for pop song composers.

The first C chord on a guitar is easy to hit with no finger twisting required. It's also easy to switch between the first C, Am, and G chord, you can even do it quickly and repeatedly while drunk as you can imagine many pop songs are written. The first F chord requires a little more careful finger placement but still easy to get too. Sure enough you hear this over and over in pop songs, some simple sequence of C F G A chords over and over.

Not surprising that the complex guitar chords that require six pencil-thin rubber fingers and a degree in music theory to know how to play aren't heard as often.

Nice post, I'm looking forward for the next one. Meanwhile I'll give my 2 cents.

The main problem in analyzing tonal music is that we mainly listen to relations between chords. For instance, in the following progression in C major, A major functions as a dominant of D (D is the dominant of G and G is the dominant of C):

    C A D G C. 

OTOH, in the following progression the same A is the subdominant of E:

    E A B E. 

This means that if a song modulates or there's a tonicization [1] the same chord will have different tonal functions and we'll listen to it differently. Just counting a chord in a song may not be enough if they have different functions.

The number of repetitions also matters. Tonally, the progressions C | C | C | G | G and C | G | C | G are the same as C | G. Is he eliminating repetitions in the analysis?

About using A major in C; you can use it as a dominant of D (see my 1st example) or as a chromatic mediant [2] in C major. Of course, in modern music you can use anything you want, but these two are the most common uses.

And, naturally, the types of chords used will vary according to the music style.

This is a good start, I'd be more interested if these chord patterns were compared against a database of UNpopular songs to see if the what sort of differences in chord distribution correlated with popular songs (although where you'd find that, I do not know). It's difficult to understand what this really quantifies - all the "2nd chord" distribution suggests to me at this point is that there's a large difference between actually playing music vs a random sequence of chords. It's good that you're recapitulating that at least, but not really a striking observation.

Regardless, I will be keeping tabs on this. Hah, totally didn't intend that pun.

What he's really talking about is chord progression (while he doesn't really say that, it's essentially the description of his first few paragraphs). Most university-level music classes discuss common chord progressions. As he notes, the I, IV and V chords are the most common to appear in a song.

It's a great article, but I think he may have done a lot of work to find out something that is fairly common knowledge lol. Still cool though to have the supporting data. (edit: it would be cool to make this an interactive piece of data presentation to help you write songs. Also, the I, IV and V chords are so popular because they naturally make people feel good. It's why they show up so often in 'pop' music. minor chords have a more depressive quality to them)

Also, if you need proof that certain chords show up often in music, just listen to some Nickelback. Here is a fun link (that I THINK works. my speaker only works in the left side ;) )

The article was down, but I assume this will be relevant: http://en.wikipedia.org/wiki/Schenkerian_analysis

We spent a lot of time doing this sort of stuff to flesh out harmonic and melodic patterns/meaning of pieces while at music school. To (grossly) simplify, it's essentially a form of reduction analysis, but the final step of the analysis is always I - V - I chord progression (tonic - dominant) with the 3 blind mice melody above (stepwise descending). I never found the final reduction particularly useful as, though he had a point about the prevalence of the tonic dominant relationship, it was over blown. The reduction steps were very useful for stripping away flourishes though, in order to see what was happening at a more base level in a piece (we analyzed a lot of Mahler this way).

Kinda like Map/Reduce in some ways.

The chord choices in Garageband are the chords found within the scale of C, plus Bb (even the Bdim - but, to be pedant, it should actually be a B7b5). Having Bb you can modulate (or "change the key") to F without having to switch scales etc.

Also, the fact that he found D, E and A among the results is probably because of modulations. It's VERY common for pop songs to modulate a whole step during some chorus near the end [1]. As mentioned, G, F and C are V, IV and I. If we modulate a whole step, from C to D, the V, IV and I are A, G and D. It would be nice to consider those modulations into the research.

About the key choice, I believe it's irrelevant. It depends a lot on what's your instrument (Bb, Eb is easier on brass instruments), your style (lots of Metal songs in the key of E because E is the lowest note on guitar), your tuning (lots of rock bands downtune their guitars to Eb or D etc), your proficiency, and, most important, the vocalists range.

--

[1] Otis Reeding - My Girl, Celine Dion - Because You Loved Me (actually lots of songs by her), Monty Python/Eric Idle - Always Look On The Bride Side of Life, Talking Heads Nothing But Flowers (If you search "whole step key change" you'll get a bunch)

The reason people fall back to the I IV V and VI chords (C F G and Am in the key of C) is that going between them creates a false sense of forward motion in the listener without actually going anywhere. Moving from the IV to V creates tension that can be built up and released by resolving to the I, or increased by going to the VI and resolved to the IV. Any combination of those pretty much sounds "good". Variations add the II (Dm) in place of the V or in between the IV and V, or add the III on the way to the IV. It's really simple, and made even simpler by power chords because you don't even have to move your hand shape to play entire songs on rhythm. Leads can then switch between major scale phrases and pentatonic (aka blues) phrases of the minor of whatever key is being played in, (so Am blues over C) and almost anything they do sounds good to the average listener. In the end, you only have to keep their attention for ~40 seconds between hooks and just crutch on the catchy chorus and you've got a hit. But if you analyze most popular forms of music, the above is at their core anyway. It's just more bare bones in modern pop and rock music.

Snnnzx.. wha?

This may best thought of as a lexical analysis of 1300 popular novels. E.G. what is the most popular word following the word "it". The key of a tune 'controls' the chords available, using a typical chord progression. A song in the key of C most typically has the progression C-F-G or I-IV-V in roman numerals signifying 1 for the dominant C, and 4 and 5 for F and G respectively the fourth and fifth notes in the key's scale.

More interesting might be what are the most popular chord progressions. E.G. I-IV-V or II-IV-Im. Which is what I was expecting to click through to.

A million monkeys can write a hit in how many years, now? And BTW "it was a dark and stormy night" don't you know.

Probably more interesting than the actual notes would be the figured chords and their progressions.

In other words, "C G a F" isn't materially that different from "G D e C" or "F C d Bb". All three are instances of the same progression: "I V vi IV" ...which happens to be the most hackneyed (or "effective", depending on your point of view) chord progression in popular music over the last 30 years.

If you transform each chord progression into its figured representation then you can pick up more significant trends such as the above, or blues changes (e.g. "I I I I / VI VI I I / V VI I I") and then you can start to discern when they rose to popularity and which ones are falling out of favor.

For example, in the 50s and 60s, I have no doubt "I vi IV V" was more popular than "I V vi IV" but I have no way to prove it currently and would love to find out if I'm right or wrong on that.

Very interesting! Although, for most common chords chart, I think that instead of simply counting the number of times a chord appears, you should have also considered the duration of that chord in the song.

Well it isn't hard to figure out chord progressions, modes and key of any song. If you wish to serve 90% of the crowd, who listen to pop music, simply "catch" C Am F G type of chord progressions. For balance, you can expose and iterate with more patterns and lead yourself up to Joe Satriani/Steve Vai's of the world.

That's a good recommendation. I have a feeling it wouldn't change the results much for pop songs.

I know Pandora has done some analysis like this for their database, but I thought it was limited to things like major or minor tonality, upbeat tempo, etc. and didn't delve as much into the nitty gritty harmony. One reason for this might be that these patterns are so universal (spanning lots of genres), that it might not be too helpful for determining what types of music people like. I could be wrong about this though.

The research is using SAT score as a proxy for general intelligence... I wonder if this sort of heuristic short-cutting actually correlates with test-taking ability more than it correlates with intellgence.

A lot of "test-taking" training basically consists of saving time by training away from full reasoning, in favor of cheap-and-good-enough heuristics. Furthermore, those heuristics are over-fitted to the particular problem types on standardized tests. I wonder how much of this study is actually measuring their ability to trigger test-taking instincts on problem types they're not designed for.

For all of the high and mightiness of this article, this bugged me:

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

If a lilypad is 20 square inches (which is probably conservative), and you started with 1 lilypad, after 48 days of doubling it would cover 1.4MILLION square miles. That is 44 times the surface area of Lake Superior.

I get the point of the question, but if you're trying to play "gotcha" on people, at least ask a reasonable question.

For the types of testing that he's doing, I suspect he's measuring boredom more than anything else, especially since he's testing largely in a university setting. Intelligent people are accustomed to being bored with endless entry-level evaluation exams, and at first glance this looks like it's just one more of them. And because the stakes here are so low (essentially zero), lots of people will just fly through without really reading and analyzing the question.

What he's seeing isn't something new, it's something so old that it's part of popular culture: the absent-minded professor syndrome. It's the stereotype of the brilliant physicist forgets what he's supposed to buy at the supermarket because he's thinking about their quantum properties. Analytic people are horrible at things that don't interest them.

Pay the students $50 for each correct answer, and there's not a doubt in my mind that the results will be the complete opposite of what he's seeing now.

"Although we assume that intelligence is a buffer against biasâ€"that's why those with higher S.A.T. scores think they are less prone to these universal thinking mistakes..."

This fallacy is at the heart of the matter. Intelligence and resistance against bias are only loosely correlated. Such resistance comes not from intelligence but from careful study and mental exercise, e.g. looking at various important ethical and philosophical arguments and analyzing them.

This is like saying all large people are strong. There is some dependance but a smaller gym-fly can kick a slacker giant's ass. The sad thing, while it is obvious that you have to exercise your body to be healthy and strong, the fact that the same is quite through fro your brain is often overlooked.

No, research did't show that "we do this" or "our approach is that" or "humans aren't rational" -- what the research showed is that the typical person does this or that.

A similar experiment where people draw the wrong conclusions is the Milgram experiment. Yes, most people are obedient to authority figures and do what they are told. But not everyone acts that way.

This research likes to sweep the best human beings under the rug, as if being virtuous is not something to try to emulate, but is something to hide. This explains why the majority of people act the way they do. Perhaps if they were taught that their "we're only human" vices are not the ideal to emulate, perhaps if the best that humanity had to offer were put forth as the ideal instead, then these lesser human beings who make up the majority would become what they might be and ought to be.

As a longtime gamer, this article really struck a chord with me. Dragon magazine used to print playable adventures, and in August 1981 (I just went and looked it up), there was a Gamma World adventure called "Cavern of the Sub-Train."

The player characters in their post-apocalyptic world come across a abandoned series of tunnels they can't explain, but which are described for the game master in the notes:

The system once spanned the North American continent and was used primarily as a method of high-speed transportation of freight. The sub-train system is something like a 20th-century subway system, in that it consists of a self-propelled train moving through an underground tunnel. Unlike the 20th- century system, however, the “trains” moved through a vacuum while being supported on super-conducting magnetic rails at very high speeds.

This idea's been proposed on and off for some decades, and is definitely intriguing. The crucial problem, though, doesn't seem to be the technology per se (though there are undoubtedly large risks there, too), but the back-of-an-envelope economics being anywhere near sensible enough for someone to dedicate serious money to it. Before anyone is going to build a London-to-NYC line, my guess is that you'd have to first show some kind of much smaller-scale demonstration, like how there were test maglev lines built.

In a quick Google Scholar search, I turn up a 1974 article on "Surface-guided transport systems of the future" (http://dx.doi.org/10.1049/piee.1974.0277, unfortunately not open access), where evacuated-tube transport gets a mention, but under this less-than-enthusiastic banner:

A brief mention is given of other less likely transport systems, such as travel in an evacuated tube beneath or above the ground.

Good luck holding a vacuum under the ocean. I read stuff like this and I think, "Gee, I don't think these people have actually built anything." because if they had they would realize that if it costs $1M a foot too build subways [1] in cities with moderately skilled labor, its going to cost $10 - 25M/ft to build something like this. That's half a quadrillion dollars (448 trillion dollars). What sort or rate of return do you think you would need to make that feasible?

I'd love someone to actually do a credible cost analysis of an evacuated tunnel train. Unfortunately I don't think Oster did.

Fascinating, and wonderful to see others are out there who are weird like me, and who will actually attempt to extend Civilization games over extremely long periods. I have a Civ4 game that I've been playing for about 4 straight years now, and admittedly the file has gotten so big that it periodically taxes my system resources to their limits (Unfortunately, Civ4 suffers from poor memory management and is fairly leaky. Especially w/ mods).

The problem with Civ4 is that the AI is so hyper-aggressive that long-term stability is all but impossible, unless I become a dominant superpower and take on the role of "world police," intervening in every war of aggression on the side of the underdog. But after awhile, there's really no fun in that. So I have tried to cultivate a game in which a few superpowers are at least my equals, if not my superiors. Since I'm always going to war to defend whoever's about to get wiped out, unfortunately, I'm switching sides constantly, and diplomacy is basically out of the question. (None of the AI players will even return my calls, so to speak. We've all nuked each other so many times over that we won't even speak to each other now).

The other problem is that the AI fights total wars by default. It will never engage in a limited conflict. No, when it declares war, it won't cease until either it's beaten or it totally annihilates its enemy. It's like a Terminator. It becomes quickly apparent that the Nash Equilibrium in a game of Civ4 is one nation standing, while all others have ceased to exist. The game drives ineluctably toward this conclusion, unless the human player puts aside his own nation's interests in pursuit of global stability and game longevity. (And, ironically, being the sole force for stability renders him a political pariah among all the other nations). It's sort of like trying to play one sport, when all the other players in the game have been programmed to play another.

Sometimes I wish the AI were more sophisticated, and/or that it could be incentivized to prefer economic growth and interests over nonstop warmaking. Or that one possible victory condition in a game of Civilization would be to maximize a global human development index of some kind (i.e., "Global Victory," instead of just one nation's domination of all others by X or Y measure, or else its complete extirpation of all other peoples on the planet). I realize that's not the game that 99.99% of Civ players want to play, but it's refreshing to hear that I'm not the only one.

The 3-way division of the world into "super-continents" and the constant war keeping the populace in a perpetual state of starvation and poverty, with the entire world in disrepair is so incredibly reminiscent of Orwell's 1984 it's scary.

If you haven't read 1984, it's a startlingly bleak view of a potential future (from a historical perspective, but still applicable today, I think) particularly through technology and a loss of privacy. It's the origin of terms like "big brother" and "doublethink" -- worth a read.

One of the most interesting excerpts from this piece IMO: "I wanted to stay a democracy, but the Senate would always over-rule me when I wanted to declare war... ...Anyway, I was forced to do away with democracy roughly a thousand years ago because it was endangering my empire."

Although I don't necessarily think it will be because of war, I can see a potential future where people/persons decide democracy is a less effective system because it's holding back the decision making process -- democratic process being (more or less) committee-based decision making, which proxies votes through individuals based on what is essentially a popularity contest. That's particularly true here in Australia at the moment (amidst a minority government with a lot of political sniping on both sides and seemingly very little real progress) despite the fact that we have a comparatively strong economy, low inflation, low unemployment and generally nothing really significant (again, comparatively) to complain about.

This was interesting as a simulation cum case study, but rather miserable as far as gaming goes.

There is no way a game of Civ II isn't eminently beatable - militarily or otherwise.

For one thing, there's no excuse to not operate as a Fundamentalism (0 population unrest) late game. Virtually all other forms of government, particularly Democracy, are an annoying cavalcade of civil unrest late game.

I enjoyed the read. It really brought me back in time to playing this game with fervent addiction in middle school.

What makes the best customer service today is the same thing that made the best customer service 100 years ago.

From the script of "Gosford Park":

"What gift do you think a good servant has that separates them from the others? It's the gift of anticipation. And I'm a good servant. I'm better than good. I'm the best. I'm the perfect servant. I know when they'll be hungry and the food is ready. I know when they'll be tired and the bed is turned down. I know it before they know it themselves."

"Do you remember the last time you sent an email and got a response back, within a minute saying, “FIXED. Really sorry that you had to experience that…” ?"

This is a perfect example of how you can turn a negative into a positive. From my own experience in the past I always noticed that if you make a mistake with a customer job but correct the mistake really quickly you actually form a bond with the customer that is much stronger than if you never made the mistake in the first place. You actually gain because of the error as long as the customer isn't in really bad shape as a result of it. (Of course you would get diminishing returns if you had to correct more than a small number of mistakes in any given time period obviously.)

The best customer service I ever got was when I was buying an engagement ring (about 12 years ago, from Blue Nile's website). It took weeks to resolve, but every step of the way the rep (Sean P -- made a big enough impression that I remember his name) communicated clearly what the problem was on their end, what solution he was looking into, and how long it would take before he had an answer for me. He was also laser-focused on making sure the solution would work for me -- right style of ring, equal or better quality to what I'd ordered, in time for me to propose.

Excellent customer service consists of being dedicated to fixing the problem, making sure that your fix will work for the customer, and being so responsive and persistent in communication that they know those things.

Answer promptly and effectively. A client can contact you at any time throughout the day; if you hear that phone ringing you better get on top of it. Good luck finding additional business streams if you get a reputation for keeping your clients waiting.

I agree 100% with the first, disagree slightly with the second. You can be prompt and efficient at resolving your customer's problems and providing them with a quality gateway to the organization, but you can't do this if your support staff is innundated by the constant pressure of answring phones. Things will come to a head where hearing the phone ring starts to become a genuine fear of support reps and CSR's will start avoiding calls just to catch up.

This comes from experience, having worked for an established software company that sold a great product, but had very unrealistic and unsustainable philosophies about support, not to mention a severely undersized team (four support reps and about 600 clients in four time-zones and one in the south Pacific)

Don't take this the wrong way, I am not saying you should be shirking your customers, or trying to find ways to build barriers to accessing that first line of defense. However I am saying you also shouldn't just assume that because you have support personnel, any opportunity for self-help and self-education should be on the back-burner. What I mean is, if your organization already has tools to help customers find the answer they need, that should be on the forefront, in the customer's face and easily accessible.

Then, and only then if your learning resources have failed, are too vague, or perhaps just doesn't answer the question in a way the customer can digest, that's when door number two opens up and it's time to contact the organization. And from there, I'm with you; be a shining beacon, be a smiling face and a welcoming gate keeper. You can learn a lot about your customer base as well as the quality of your documentation by following this strategy.

If you want a qualitative and effective team, don't toss them into the middle of a category 5 hurricane, trying to answer phones and create tickets at the same time. This will erode quality AND effectiveness.

Great post, otherwise!

I'd add one more item to this list: If you can't give your customer what they're asking for, explain why.

I regularly take calls from people asking for features that we don't offer (and probably never will). They normally start out annoyed that we don't have what they want, but after I explain why we can't offer the feature, they normally understand completely and it doesn't seem to bother them at all.

Most customers don't have much perspective about your business. They know what they want, and they're not really thinking about how it might effect the overall experience. If you just say, "no, we don't have an iPhone app" they'll think you're brushing them off. Instead say, "I totally understand why you want an iPhone app, but if we made an iPhone app we'd also have to make apps for Android and Blackberry which would mean we couldn't spend nearly as much time focusing on making the core product better, which is why we have a mobile website which will work on all platforms". The customer wasn't thinking about that when they requested/demanded the feature. By explaining your reasoning, you're telling them that you really are listening to them and considering their ideas, but there are good reasons why you can't give them exactly what they want.

Am I the only one that thinks "Ugh, not making money yet"?

Yes yes, I know about burning cash (err, growing) as fast as possible to lock down winner-take-all markets, but travel booking doesn't seem like one of those. There doesn't seem to be any switching cost other than typing a different url in the browser. I don't see any network effects. Am I missing something?

This is a business with revenue streams and cash flow. They've been around for two years. They've already raised more than $5mm. When I hear "we raised another venture round" my gut reaction is concern, not congratulations.

Can someone explain how do these free flight search engines make money?

In my case I search using Kayak, but never really book the ticket from Kayak (don't follow their link to the airline). I go directly to the airline site and book it there. Many people I know do the same. I despise using Orbitz/Priceline other than just a cursory glance to see if there are cheaper tickets.
I know that sometimes an itinerary involves multiple airlines and that is when there might be an advantage booking through, say Orbitz, but even in those cases I just book separate tickets.

Why is this free search/booking industry still unsaturated and is there really a demand for such capital infusion?

Update: My question is specific to flight search, because I think hotel search can be profitable model as sometimes these sites provide better rates than the hotel's site.

I am a Linux user, and I have wrecked laptops with it before. It is easy to overheat or otherwise abuse a laptop by having improper configs.

For example, I had a battery become unusable because Linux often failed to sleep when the lid was closed because some dialog box was blocking. It would run in the bag with no ventilation when I didn't realize it until the battery drained and it would fail to shutdown until the hardware fail-safes took over and I realized my backpack was too hot to hold. Did this a few times and the last time, the battery wouldn't charge anymore. After getting a new battery I became very conscientious about whether it actually was asleep before I put it in the bag.

I have had this happen in Windows before as well, in one case it would wake up if I forgot to turn off my Bluetooth mouse when I put it away. Since it was already closed, there was no trigger to go back to sleep so it would run itself dead in the bag and eventually the plastic near a hot component melted. Turns out there is an option in the Windows device manager to tell it not to wake on Bluetooth that prevents this.

However a defect in the factory-installed operating system that causes failure is something you have to warranty. A defect in the user-installed operating system is not. However, I have no idea how they could trace the problem to the operating system. Not sure how they would ever know that Linux is installed. Any good Linux user would wipe the hard disk before returning a computer to the manufacturer for repair :)

It just took a ton of kicking and screaming to get there, which really wasn't worth it on my part, but in the end, they did the right thing.

One thing I'm seeing more and more is that companies are holding back their lower tier support employees from actually being helpful. For example, have you ever had one of those "Instant Online Chat Support" things help you out? No, they are always so unempowered its not even funny.

I now try to buy all my electronics at Amazon instead of NewEgg or TigerDirect due to the poor return policies at Newegg and TigerDirect with DOA items. NewEgg used to be better than it is now but they have gone downhill in the past two years. TigerDirect has always had poor return policies.

This is NewEgg's chance to either gain or lose 1% of its customer base. Since margins are so tight on computers, and NewEgg costs for software support will decline, isn't this a no-brainer from a business perspective?

Note that the NewEgg's refusal is based on the original OS being missing rather than a new OS being installed according to that email. My guess is that the user formatted the HD before installing Linux. Most OEM PCs now come with a recovery partition which is used to perform a factory reset. If the user erased this partition, then NewEgg would be unable to reset the device to its initial state for testing. It would be similar to the user returning the device by not returning important CDs.

Newegg used to be awesome - I have spent thousands in the last 6 years with them, but their customer service is terrible. Their customer service pretty much reads a script and keep repeating the same thing.

I think all companies have a life cycle:
1. New company, so customer is treated well/
2. Company grows and becomes successful
3. Company needs to show ever increasing profits. Starts taking shortcuts to save money, and starts to ignore what made them great in the first place.

> 7. The stolen info is sent out by infecting USB sticks that are used in an infected machine and copying an encrypted SQLLite database to the sticks, to be sent when they are used outside of the closed environment. This way data can be exfiltrated even from a high-security environment with no network connectivity.

> "Agent.BTZ did something like this already in 2008. Flame is lame."

Flame's approach is different and more impressive. Agent.BTZ copied itself and used an easy-to-discover autorun.inf file in the root directory of attached disks or network shares. Flame exports its database by encrypting it and then writing it to the USB disk as a file called '.' (just a period, meaning 'current directory')

When you run a directory listing you can't see it. You can't open it. The windows API doesn't allow you to create a file with that name and Flame accomplishes this by opening the disk as a raw device and directly writing to the FAT partition. Impressive, right.

While a lot of these individual features alone are not impressive the sum of the parts, combined with the collision attack on the certificate signature are very impressive.

As for the main point of Mikko's post, I have never understood why so many folks in the netsec industry are arrogantly pessimistic about the innovation of others. I found Flame jaw-droppingly amazing.

Nobody knew about it for years, yet it was derided when discovered and documented.

It doesn't really matter whether the nation state in question is Iran or the United States.

The thing I find most interesting about Flame: whoever developed it surely understood that by being released into the wild like this, their new cryptographic attack was guaranteed to eventually be discovered and analyzed. And yet they spent that attack's secrecy on a (very sophisticated, but still) fishing expedition.

So what cryptanalytical capabilities do they have which are considered too sensitive to expose via malware?

django-twostepauth (https://bitbucket.org/cogni/django-twostepauth/src/79bbf0ce3...) is a Django app that works really well and has an exampleapp that makes it as easy as can be to try out. Setting up TFA with Google's authenticator is a breeze.

Unfortunately, the release of Django 1.4/django-registration 0.8 (https://bitbucket.org/ubernostrum/django-registration/src/27...) complicates matters a bit, and I'm torn between figuring out a way to keep my TFA or just roll it back altogether and implement d-r, and see if it has support for TFA.

If you're using Django 1.3 with something else than the default password-hashing, you should check out django-TSA.

It annoys me that a trick is missed with the secure fob. Imagine that: the challenge screen includes the amount you are authorising and you type that amount into your secure fob along with the challenge code

That's basically how the auth works on with my online bank. I get a small calculator sized device that reads my debit card. I have to enter the card pin, a challenge code from the online transaction, and the amount - which then gives me a code to authorise the online transaction.

(The downside is that the devices are all identical - so anybody with one + a cloned card + my stolen login info can auth transactions - hey ho...)

The way it's commonly implemented, two-factor authentication is definitely not "a step in the right direction".

Two-factor authentication using phone numbers is a huge privacy breach, especially when you're dealing with websites that have no business knowing your phone.

And rolling code tokens aren't feasible for anything except some really high-security applications. Even there, I doubt they are really much more secure than a USB stick with your paraphrase-protected private key. Sure, you can't copy the token, but that doesn't just add to security, it detracts from usability.

Please do not be a contrarian who buys ZNGA. You will probably lose money.

They have 3,000 employees,[1] even though their business model revolves largely around cloning[a] games that are simple enough for very small teams to create.[2] They're losing money; their EPS is -1.30.[3][4] Just because they have cash from investors doesn't mean that the business model will make significant money in the long run and it's made more complicated by the fact that they have a very heavy dependence on Facebook.[5]

They're also dependent on casual gamers (who don't have much loyalty or will to pay) and current trends.[b] Apparently, only 2% of their customers pay for their games.[5] Their stock market valuation seems largely mapped to their active user count[6] (and also Facebook's share prices[5]) rather than their financials.[c] In fact, I can't even say that they're overvalued because that involves looking at the P/E and with a negative EPS, I can't really do an apples-to-apples P/E comparison of Zynga against companies that are actually listed as profitable. Is a -3.8 P/E overvalued?[4] It certainly is risky!

-----

[a] They also buy some companies behind popular games too, like OMGPOP. This isn't necessarily a good idea.[7]

[b] The use of the term "game craze" in the title of the parent article implies that part of the reason ZNGA has a valuation in the billions is because of the current trendiness of Facebook games. The problem with relying on trendiness for investments is that when there's something even trendier (i.e. mobile apps), all the investor money that chases trendy stuff could simply go there instead.

[c] It was a popular dot-com bubble plan to focus on market share with a free product at a sustained financial loss.[8] Of course, it's too early to tell if ZNGA will sustain its losses in the long run because its stock is too young. Still, it's very risky.

ZNGA's current market cap is $3.5B. But it has about $1.2B in cash, and little debt. Regardless of how you feel the games, they do have a real business, so if Instagram is worth $1B to Facebook, ZNGA must be worth somewhere north of $2.5B, its current enterprise value.

Zynga is said to be moving games into the mobile market, but you also have to figure that being a gaming company is hard. You're top-rated game will be supplanted by something else in short order and you have to constantly be updating.

I think that the way Zynga acquired its customers/users is exacerbating the situation. If your friends are all there you feel compelled to join too, but if some leave it's socially acceptable to follow them elsewhere.

Since we're talking about "social" gaming, I also have to wonder whether part of the drop isn't seasonal ... at least where I live, it's now nice enough to spend a lot of time outside socializing (picnics, frisbee, t-ball, etc) so perhaps there's just not the boredom to drive as much traffic?

The description of the retransmission timeout is kinda wrong. All modern TCP stacks (at least Linux and Windows, not sure about OS X) implement the selective acknowledgement ("SACK", see RFC 2018) option by default[1]. The receiver will notice the out of order sequence numbers and immediately push a SACK package back to let the sender know about the drop.

And if you look at the charts, that seems to be exactly what happens. At low-but-nonzero packet loss rates, the maximum delay is never more than one or two RTTs. With high packet loss rates, you start to see a long tail of longer times due to double-loss events, I suspect.

[1] "By default" becuase it can be turned off. SACK can be used as a DoS vector by forcing the sender of a large transmission to buffer and reprocess essentially all of it repeatedly by pretending it "lost" a packet.

"I really wish the $2199 SKU had the 512GB SSD, or at least offered it as an option - otherwise the spec is near perfect in my mind."

Many of my colleagues agree. Slower cpu with 512GB at ~$2500 would be just about perfect.

I really don't like the approach of hiding the display's real pixel size. By now, we should have solved the problem of displaying GUIs with correctly sized elements at various resolutions. This approach only makes it more complicated to do it right in the future.

The smart move now will be to wait 2-3 months before buying the Retina Display machine. I'm convinced that by the launch of Mountain Lion the OS will let you use the full resolution of the machine for UI, also it will give some time to other apps to upgrade their UI in order to support the new resolution.

While the upgrade to Mountain Lion will be free, I have a funny feeling that Adobe will charge (or at least will try) you some extra money for an updated version of Photoshop for Retina Display MacBook Pro :).

Any self respecting company or individual developer will probably provide a free upgrade for the UI of their applications soon in order to support the new resolution.

Why are they faking the resolution? Is it that the graphics card has problems, or is it to make their own apps look nicer than competitors, or what? I hope they are not rescaling stuff like photoshop to something other than actual screen res, otherwise they will severely piss off graphics professionals even more than they managed with the Mac Pro workstation non-upgrade.

[edit] reading through the article, it seems that they've either gone and broken the word 'resolution', or Anand is very confused.

At 1440 x 900 you don't get any increase in desktop resolution compared to a standard 15-inch MacBook Pro, but everything is ridiculously crisp.

I have read this sentence three times and it still makes no sense unless the word 'resolution' has been completely mauled by marketing idiots.

I was worried the Retinabook was only going to double the pixels. The ability to select a 1920x1200 "mode" is awesome.

I buy a new MacBook Pro every year, and the dilemma here is similar to Anand's. I bought the high-resolution display on my current 15.4" MBP at 1680x1050. The resolution can be scaled to 1680x1050 or 1920x1200, but I'd like to know how blurry that is as opposed to native resolution. I've flipped my current MBP to 1440x852 to get a feel for the same effective real estate as the Retina Display's native resolution. Will try it out for a few days before pulling the trigger on upgrading.

For creators, one of the reasons to own these devices is to create content for retina devices.

I'm curious of Apple and Adobe have worked together to allow image documents to display at true resolution, within a scaled output?

Does that make sense? I suppose what I'm saying is, working at a 100% canvas at 100% zoom level (instead of say, a 50% scale level) while all system elements are scaled.

EDIT: This might not even matter, from a practical perspective.

Interesting to see Tim Bray (http://en.wikipedia.org/wiki/Tim_Bray) still being active at this level of the web's development.

Not sure I see the applications of this, but I guess more high-level error messaging is something that is in general a good thing so I guess that should hold for the web, too.

If something didn't exist at all, why would I send a 451?

So... everybody can ignore 451?

The 400 series implies that there was an error on the client side, when there clearly isn't one. The client has made a valid request that a middleman refuses to honor.

This better fits into the 300 series as a permanent addition.

First of all: This is a stupid question.

Second:

The solution is simple, copy a tarball of the source to CD and throw it inside the casing of the missile. Add rocket fuel to compensate for the added weight.

EDIT:

Third:

That was an intentionally stupid answer.

The GPL only states you have to release the source to people you distribute the code to, not directly make it publicly available. If the missiles work well enough when "delivered", there will be no one left eligible to demand access to the source!

Assuming that they are not selling them to someone rather than firing them at someone, of course.

Even if it is, the first sale doctrine would likely apply and so it would not require the permission of the copyright owner.

Whether this is the case or not depends on whether or not the Navy is making copies, or just passing along copies they received from a contractor.

An Introduction to Lock-Free Programming preshing.com

Nice article, though I think that any intro-level material on lock-free programming should always include a "don't try this at home for anything important" warning. Until you have some experience with this stuff you will almost certainly make mistakes, but these mistakes might only manifest themselves as crashes in extremely rare circumstances.

I wrote my first lock-free code in 2004 based on reading some papers by Maged Michael from IBM. I wrote a lock-free FIFO in PowerPC assembly, and was convinced it was safe and robust. When I emailed Maged about it, he pointed out that if a thread was suspended on one specific instruction and some specific memory was unmapped before it could run again, the program could crash. I was amazed; I had thought hard about this algorithm, but had completely missed that possibility.

Some other specific notes about the article:

> Basically, if some part of your program satisfies the following conditions, then that part can rightfully be considered lock-free.

The are actually several levels of lock-freedom defined in the literature: lock-freedom, wait-freedom, and obstruction-freedom. For more info see: http://en.wikipedia.org/wiki/Non-blocking_algorithm

> Processors such as PowerPC and ARM expose load-link/store-conditional instructions, which effectively allow you to implement your own RMW primitive at a low level, though this is not often done.

One benefit of load-linked/store-conditional (often abbreviated LL/SC) is that it avoids the ABA problem (http://en.wikipedia.org/wiki/ABA_problem). In practice this doesn't matter that much since x86 doesn't support LL/SC, but I just think it's an interesting factoid to know.

> For instance, PowerPC and ARM processors can change the order of memory stores relative to the instructions themselves, but the x86/64 family of processors from Intel and AMD cannot.

(I've edited my reply here since my original assertion was incorrect). It's true that x86/64 won't reorder stores (see http://en.wikipedia.org/wiki/Memory_ordering for details) but it will reorder loads, so memory barriers are still required in some situations. However I believe that the atomic instructions ("lock cmpxchg", and "lock xadd") imply full barriers on x86.

The idea that made this click for me 10 years or so ago was that distributed systems express concurrent processes but can't reasonably use locks; model your threads/processes/whatever as if they were nodes in a distributed system, and use distributed system techniques to ensure things converge.

There is also a niche research area of lock-free data structures and algorithms.

On a more practical side, check out http://www.liblfds.org/ -- it is a library of lock free data structures in C. (I am not the author). I have successfully used this library in some realtime projects.

Very good overview. I've built lock-free hash maps, and this article covers the areas you need to be aware of. I'd also suggest looking up false sharing, and also making sure that you really understand exactly how the memory barriers are operating.
