The problem with this kind of advice is that it is based on conscious goals and requires staying focused on one goal for an entire year. In my experience (and I believe research tends to support this) humans have a hard time giving conscious goals priority over unconscious needs.

As far as I can tell, the best way to work toward being the person you want to be is to trick yourself into making a habit of it before it becomes too onerous to the lizard brain. It's only things that you do without thinking that will be able to override the desire to sit on the couch and consume calories.

Not that I think reducing distraction and cutting out that which is not necessary is bad, but when putting it into practice involves making all these lists day after day it starts to sound like New Year's resolutions -- ready to be abandoned by February.
That may be the setup of that project, but it isn't the status of every decentralized system. A decentralized system could as easily be funded by individual users buying hosted space with professional admins.

I think your attitude to sleep changes as you age. When I was a teenager, all-nighters were tiring but after a night's sleep I'd be back to normal.

These days, it takes me a week to recover from an all-nighter.

The thing that really got me thinking about sleep as a precious resource was being diagnosed with obstructive sleep apnoea. I was getting to the point where I was sleeping for 14 hours and waking up exhausted.

The year I got a CPAP machine, my grade average jumped from credit to distinction.
Same here. Though I can't find it now, (I think it was) Joel Spolsky had a piece about individual offices in which he claimed study after study found individual offices to be the most productive for programmers. Certainly the case for me - productivity is all about how many mental balls I can have in the air at once. The more distractions I have the less productive I am.
You do realize that the whole point of these games is socially engineering people into parting with as much money as possible, right? They're paying money for a chance at winning certain pixels and you're pretending in your head that they're all wealthy millionaires and justifying it to yourself.

If you don't want to make games for addicts perhaps you should stop working for companies that make games for addicts. You're not fooling me.

The main point is that if they line up credentialing that mirrors Udacity's courses, they can offload the cost of curriculum development and course management and sell the exams and degree, at a substantially higher margin. They can also offer a pure CS degree instead of the IT and MIS degree they currently offer.
It's relatively well-documented that sleep deprivation has effects similar to those of alcohol intoxication, but coming in to work drunk is a firing offense, while working to the point of sleep deprivation is regarded as heroic. Of course, these aren't quite the same, but I still wish the idea that your dedication is measured by your level of self-destructive sleep habits weren't so prevalent in the tech industry.

The formula aside, I thought that inflation was actually calculated by charting the price deltas of a 'standard basket of goods' [1] [2].

In which case, assuming that Output can be measured with a reasonable degree of consistency (economic output of a nation) and assuming that money supply is controlled, then V can be calculated. More importantly V can be used as an instrument to control inflation.

I guess the complications come from the side effects of manipulating V, and increasingly (especially for non-US countries) the impact of foreign economic factors.

Also the measurement of inflation has a built in delay (eg: you measure the aggregate inflation of the previous quarter) which can be problematic if inflation is changing.

I am not an economist, but this is how I understand things.

[1] Depending on who is calculating inflation, sometimes these prices are seasonally adjusted.

[2] I somewhat oversimplify things. See http://www.rba.gov.au/publications/confs/2009/ravazzolo-vahe...
On a similar note, the importance of taking breaks where you're doing something TOTALLY different is incredibly crucial. By this, I do not mean playing a quick game of angry birds.

If you're coding, writing, doing research based tasks or basically anything where you're at a computer or in a book, the difference going for a walk makes is incredible. It's taken me about 4 years to accept that even the hardest problems sometimes fall into place during a shower, while walking to get a coffee or just through going somewhere physically different and talking through the problem to yourself - no pen, paper or screens allowed.

I don't get too much out of breaks every 45 minutes, and when things are going well am happy to work 2,3 even 10 hours straight, but if I've been stuck on something for more than 20 minutes 9 times out of 10 if I leave and come back I can solve it pretty much instantly. It's like a reset button to my mental state, and I'm always pleasantly surprised with the result.

#1) If it was easy they would have done it. Pushing photo deletions up to the CDN is hard without flushing the entire CDN cache. And Facebook has 90 billion photos, so flushing the cache is not an option I guess. (Wrap your head around 90 billion photos. The scale of the problem is huge.)

#2) Anyone with access to the link to the CDN had access to the original photo. So this really doesn't protect someone from viewing your photos you wanted to delete - since if they wanted it before they could have had it.

So ultimately this should not bug you the greatest of all the bad things they have done. The ultimate blame belongs to the person who uploaded the photo to Facebook and then later wanted it deleted.

Your comment is so true. I currently live in Japan and I see all the sleep deprived Japanese going about their jobs in the laboratory, sleeping in the desk or dozing off while trying to work.

I had a talk with them trying to ask them if they realize that better sleep would make them more productive and also improve their overall health but their belief seems to be as you say. They think it's heroic to stay up late working and as a consequence be a zombie next day.

And once you start this it's a vicious cycle that is pretty hard to stop. Nothing can increase productivity and mental stability like a good night's sleep.

Isn't this the point of any business?

> If you don't want to make games for addicts perhaps you should stop working for companies that make games for addicts.

I don't believe we make games for addicts. When I show our game to my friends and family they say things like "oh this game is cute", "this creature is funny", etc. The vast majority of our users are people who enjoy casual gaming when they're bored sitting on a plane or on the train.
> If humans didn't age, weaken and die, would you vote to introduce it?

No. My advocacy of aging is based on the fact that it was a balance achieved by evolution. Every piece of evidence we have about aging points to it being a well-balanced and curated process of either evolution or design, whichever you prefer.

There are plants on this planet that live thousands of years. Animals that live hundreds. We are not among them. If you think that's a result of bad luck or some such thing, then I'm sorry, you need to go read a bit about evolutionary biology.

Longevity is a trait, crafted by an evolutionary path and the environment. Our life-spans are not an accident. They are not random. They are optimal.

They might change over time. Get shorter. Get longer. Whatever the optimal solution, I'm for it. However, I'm definitely against treating various parts of our nature as if it is some sort of a disease.

But doesn't the federal reserve uses Consumer Price Index(CPI) to measure P. Looking at how CPI is measured, it doesn't seem like it has a strong correlation with M. Cost is directly related to M, but price is not. Under these circumstances, doesn't it encourage merchants to artificially up the sales price to maximize their profit, regardless of the cost?

Hey Jacques, thanks for the kind shout, yes, really glad others often have similar thoughts to me.

That's very interesting and I think you are right, it changes as we get older and we need to adjust. What I am most interested though is to find a pattern that works no matter what age and I felt this 8 hours/night + half an hour comes pretty close.

Wow, that is quite an example there of what can happen and a great reminder to look after it, thanks for the heads up!
and if the fed tries to lower the value of dollars to counter act this, wouldn't it ultimately dilute the profit of those who maintained the lower price? Thus starting the vicious cycle of price hikes
So the difference is making changes to optimize for a subset of users vs. optimizing for the aggregate?

Exactly. Vi isn't a teacher, either. Khan hired her to continue doing what she's been doing for quite some time: Make math inspirational and interesting. She didn't even take any math courses at university. She's just incredibly passionate about its odd applications.

I know more than a few artists who self-describe as math haters who changed their tune (if only briefly) and searched their souls for the true meaning of shapes after seeing a few of Vi's wonderful videos.

Have you seen Rain Man? Remember that control room from which the casino executive monitors what's going on on the casino floor? That dashboard is your virtual control room. To me, the "free-to-play" social gaming industry appears to be eerily similar to the gambling industry. You even use the same terminology ("whales"). And the gambling industry has always been a little shady, trying to squeeze as much money as they can out of people who can't really afford it. Maybe that's why it appears creepy to some of us?
Sorry, not at the moment. Perhaps in a few weeks, once things have stabilized...
I don't mean to sound snarky, but: that's because they hire people who know how to merge linked lists or reverse words in a string or (insert interview problem du-jour) ; they don't hire people who can really solve real-world problems.

I may sound old when I say this, but my impression of interviewing there was that they're just a bunch of kids who like working on 'cool' or new things, and don't really care much about the real-world impact.

No, this is not sour grapes; I was recruited for my skillset, but was really disappointed to be tested on bullshit problems; I pointed out specific issues with their site that needed fixing and how they could be fixed, but it didn't really matter to them.
I adblock YouTube comments, personally. I suppose this is a cute modification of that same idea, but I'd rather not have to get another extension when ones I have already suit that purpose.

I think having all that information is fine, but the issue is Zynga just focuses solely on that, they don't try to make games fun. They just make games to make money, even taking out features that are fun to users. So do you measure those metrics and say, "this feature doesn't make enough money so we're gonna cut it even though users think it's fun?"
It seems clear to me that's he's talking about the performance / complexity of the algorithm that the article was about? There was significant discussion of the performance in the article, but the original commenter didn't have anything to contribute but a sassy comment. I'd be interested in hearing more about why he/she disagrees with the author's arguments, but frankly, a one-line criticism deserves a one line rebuttal.

Also -- I'm not sure the comparison is accurate. Preemptive multitasking involves suspending the running process, while the author's suggestion involves emptying the queue behind the blocking process... or am I misunderstanding?
I know some people who intentionally leave their source tree in a broken state...

This sounds like a slightly forced version of Hemingway's method:

"The best way is always to stop when you are going good and when you know what will happen next. If you do that every day … you will never be stuck. Always stop while you are going good and don’t think about it or worry about it until you start to write the next day. That way your subconscious will work on it all the time. But if you think about it consciously or worry about it you will kill it and your brain will be tired before you start."

(i.e. stop for the day when you know exactly what your next step is, not when you're 'finished' and definitely not when you're stuck)
Was that actually in the submission title here at HN? I didn't put that into it and it's not there now, so if it was.. we know an admin was fidgeting with it! :-)
That is a great answer, Thank You.

Now to pick your brains a bit. :)

What are some good resources for engineers to pick up some advanced analysis skills (specifically to do the kind of work you do)?

Is it as simple as going back to college to do some courses in Advanced Statistics? Any particular sub branches of stats/math to focus on? Any good books you can recommend ? Thanks in advance.

PS: I work in Machine Learning,and am fairly knowledgeable in maths/stat but often have difficulty recommending the right sequence of books,courses etc, to people who want to follow a similar path - it doesn't help that I am entirely self taught - and often have to mumble vague generalities like "learn all the math you can and learn to code really well" etc. Recently I am getting questions about how someone can get good at "data science" and "behaviour analysis". Just wondering if there is a standard learning path for something like "casino science"
It is not theft. After review Google refunds the earnings to the advertisers who, from Google's standpoint, the publisher is stealing from via click fraud.

And I speak from experience. I know this because a very large ad based site of mine was banned for being in violation of a vague line in their TOS. It was automated and I really didn't know what I was doing wrong. After a month of writing every contact form and google email I could find, I got an actual response and was reinstated after being told what I was doing wrong. Afterwards they withheld a large amount of the prior month's earnings which they refunded to the advertisers.

Sadly, though I was technically in violation, they simply showed me another way to do the exact same thing. There was no fraud, and I was out about two months revenue, but at least I now have a few direct contacts at Adsense for the cost. Very, very expensive contacts...

My main point however is that Google does not keep a penny of the withheld funds. It goes back in full to the advertisers who paid for those clicks.
Very well put. I have lost entire days in the 'zone', starting at 10am and ending after dark, not even realizing that other in the office have left.. It's kind of like time travel :)

Mmm, I think this really highlights the issue that facebook is not a public space. It's private. You can campaign all you want but this isn't womens lib. This is a private business that has their own rules. You want real freedom of expression? Facebook doesn't care. They just want their earnings to be as high as possible.

I'm by no means saying that facebook is doing anything close to the right thing. Exactly opposite. But I think theres a gross misconception among the general public that people somehow have any rights whatsoever on facebook.
We use Varnish because it's configurable, and have 6-8x more app servers than cache servers. In the future we'll scale back the Varnish layer, since more and more of what it does will be handled via CDN.
That is a good point. And actually I didn't know we used the same terms!

I'm obviously aware of what goes on in the industry and its similarities to gambling are something I think about a lot. But as an analyst, I feel like I have a lot of power in helping to create games that are fun and engaging, plus learning how to drive a product to be successful. I don't think of it as a spam machine or a front for taking money from the poor.

Maybe the business model needs to be changed. If its virtual currency that makes it creepy, then maybe switching to a fixed-cost product is something the industry as a whole needs to move to. We're still in the infancy here in learning how to harness mobile devices to make better products.

That vast majority of your users account for what, like 10% of your revenue, or less? The real point of your product is targeting addicts, whales, as you called them, and manipulating them into paying money for nothing. Yes, actually nothing, because you rig the odds and dangle carrot shaped pixels above their heads and use every psychological trick in the book, the state of the art, to get them to keep playing.

That is not the point of business for me, most businesses offer something of value.

I measured the headers in ajtaylor's above post. Zappos delivers different headers each time, and currently they're only giving me 599 bytes, including zero Link headers.

I agree of course that you can't consider all of it a waste. My point was just that their HTTP overhead is exceptionally large, and their superfluous headers adversely affect all of their users despite the fact that almost none of their users will ever read them.

The fact that their X-Core-Value in ajtaylor's example was "8. Do More With Less" makes them seem clueless about the real impact of HTTP overhead.
The comment was no more speculative than its parent.
Honestly I don't know why, but I haven't seen any game doing it and there is no infrastructure to do behavioral targeting.
