ok, for example: I upvoted here because as much as this does not bring any new knowledge to the table, #1) it is unusual news to begin with, and more important #2) I am dying to hear other HN users commenting on it.

Investors literally said they weren't going to invest for at least 6 months and see how the economy fairs (and it didn't fair well) ... so even legitimate businesses were getting overlooked.

Sounds like a golden time for a contra market investor.
So, the behavior you're talking about is basically treating the tab bar as a hybrid "what I'm about to read after closing this" and "what I stopped reading and might get back to after closing this" queue. For this type of browsing behavior, I would go even further than just not restoring tabs. I would unload backgrounded tabs with "simple" content[1] when they've not been in use for a while (say, half an hour, plus not being in the 5-10 most-recently-used tabs), only keeping the URL and, say, the scroll-position. (Plus maybe <input> contents if you don't want to be cruel to the web developers who haven't yet heard of localStorage.)

[1] It would be interesting to define a heuristic for what qualifies as a "simple" webpage. Perhaps anything that doesn't do any JS setTimeouts or websocket connection creation would count? It'd likely be best to just leave it to the web server to declare "simplicity" of a page as a header, the same way companies can declare "recyclable" on boxes. One would wonder if any company would bother to use this if it meant their own tab would seem slower-to-reload than their competitors', though...

I'm expecting the book to go much further than this. Your list is a fine starting point, but its fairly basic and lacks specifics.

I want to know about the weird things that happen when you push your PHP stack to really ridiculous limits. I think that's what this book will offer. If it ends up being stuff like "use APC! minimize trips to the DB!" I would be very surprised and disappointed.

There was an idea in 'Fat Head' where the narrator pokes fun at the idea that we are a species who's evolution has made us so that we crave foods that are actually killing us. It's not proof that we can't crave foods like sugar, fats and salt that might be harmful to us, but I think it sets up a health amount of skepticism towards the idea that our innate cravings are in fact harmful.
How to show something in actual life size on any computer screen
I'd like to share with you the site I've been working on for the past year and a half... It's called LifeSizer, and allows you to view any product in it's actual true size on any computer screen or mobile device. I came up with this a few years ago when I bought some jewelry for my wife, but after I received it the earrings turned out to be much bigger than I expected. That started me thinking: why isn't it possible to get a better sense of the size of a product on most ecommerce sites? Wouldn't it be great if you could view products in their actual size on a screen, so you really get a better idea of what it is that you're buying?

The technical challenge here was obvious: To be able to display anything in true size on a screen, you'll need to know the pixel density of that screen. Unfortunately there's no way to determine that programmatically (at least not from within a browser). You can calculate it based on the current screen resolution and the physical screen dimensions, but that actual screen size is an unknown too.
The beauty (I think) of the solution I came up with is that it allows me to determine that screen size (even if the user doesn't know it himself) by using a simple calibration trick. And we've built in such a way that it can easily be integrated with other sites, here for example: http://mwctoys.com/REVIEW_060412a.htm (see the second image).

We're officially launching today, and please check it out here:
http://beta.lifesizer.com/images/featured

I would love to hear input from the community on what you think. Have you ever bought anything online that was much bigger or smaller than you expected? Do you see wide scale use for a feature like this? Would you use it on your own site? How can it be improved further?

thanks!

The elaborate on the Schultz paper, dopaminergic reward feedback mechanism is for unexpected reward only. Repeated stimulation depreciates the neuronal signals.

As I'm still working through this stuff, and am certainly no psychologist or neurobiologist, did I say anything above that was contradictory to this? It sounds like you know more than I do about the subject (I'm dabbling in it for my Computer Science thesis) and I'm always paranoid that I'm overstating or overgeneralizing some experiment result.
Not sure where you live, but there might be a Makerspace nearby you can utilize.

Why the emphasis on state sponsored attacks? (I am aware of stuxnet/flame/sanger's book) If google knows I am being targeted by a non-state actor are they choosing not to notify me? Are we going back to a cold war mentality where the only credible attacks are state sponsored?
I think part of the problem with MSG is the name. It's hard to convince the general public that something with the name "Monosodium Glutamate" is a naturally occurring substance, let alone one of the more abundant naturally occurring amino acids.

Hell, if we called table salt "Sodium Chloride" all the time, people would probably have a bit of a changed perspective.

None the less, MSG is delicious!

I'll be 100% behind this project when it has as much control over a device as Tasker does. Recipes in JavaScript and not having to "program" on the device itself are exactly the kinds of things I wish Tasker could do. The modeOfTransport monitor is pretty attractive too.

Beyond all that, I'm curious about on{X}'s battery usage. That's a huge selling point for always-on processes like this.
So, I always cringe a little when I read medical conclusions in the mainstream media. And I'll be upfront. I'm probably biased on the side of medicine on this one. I'm a former nephrologist.

The one study this person mentions by name (and dismisses) is the DASH-Sodium Study.

http://en.wikipedia.org/wiki/DASH_diet#Study_Results

"Like the previous study, it was based on a large sample (412 participants) and was a multi-center, randomized, outpatient feeding study where the subjects were given all their food."

"The DASH-Sodium study found that reductions in sodium intake produced significantly lower systolic and diastolic blood pressures in both the control and DASH diets. Study results indicate that the quantity of dietary sodium in the control diet was twice as powerful in its effect on blood pressure as it was in the DASH diet."

So, positive conclusions (lower salt -> lower blood pressure) in a seemingly well designed study. People were randomized, it was prospective, and people given all their food. So, change one thing and see what happens.

The author here seems to cite other studies to make the opposing case (low salt = bad), but doesn't give exact references. I did a quick google search and found this one: http://www.nytimes.com/2011/05/04/health/research/04salt.htm... But you can already tell it's an inferior study. "It involved only those without high blood pressure at the start, was observational, considered at best suggestive and not conclusive."

So, let's try to compare apples to apples.

He points out that the DASH study didn't conclude anything about death or cardiovascular disease. Yes, that's true. So sure, there's a chance that despite blood pressure reductions a low salt diet could cause problems. But it's not the obvious conclusion. Anyone have any solid studies on this?

Taube's theory (about cholesterol, but I think it applies here as well) is that it's "where the light is". Things which are measurable are optimized for even if they're pragmatically pointless.

So a study comes along that finds a correlation between sodium intake and cardiovascular disease. Totally possible. The USDA looks at those numbers and says, we're eating Xmg of salt, we should be eating Ymg. They make a recommendation, years go by, and they look at the numbers again and, hey, salt consumption is down to Ymg! Success!

What about mortality? Who knows. That's not their department.
Problem is, X will change based on a bunch of factors - type of browsing, screen real-estate, etc. If that isn't taken into account, it could result in what the user perceives to be a jarring interface shift.

We could use much more subtle algorithms - what about loading visible page, then queuing up X background tabs to concurrently load (based tab order)? What about a logarithmic backoff (ie, load up visible and several background pages, then slowly load others)?

Fact is, user-time is valuable, compute time (and for most users) bandwidth is not. What's valuable should be prioritized.

My kids grandparents are more appreciative of a photo in a frame or a drawing on the fridge than an image on a screen. Of course they can pick and choose if I chose to post those photos on Facebook, but I also take pleasure in curating and actually spending money to create a print (if I spend money on something, I'm more likely to do a good job.)
I don't mean to beat this to death, but any kind of statement about moderation presupposes that we already understand how different amount of some substance will effect us. The topic under discussion boils down to "what is too little, what is too much and what is moderation?". You cannot answer that with "just go for moderation" when moderation is precisely what we are trying to define.

I see this kind of thing all the time and it irks me because I see so much agreement with what amounts to a circular statement.

While in principle I agree, I think you may also want to consider the fact that most people do not have formal training in engineering (or anything technical, for that matter). Most HN readers probably do, but what if the article wasn't written specifically for HN readers? So this way of thinking systematically is new/unfamiliar for a lot of people.

I would argue that 'common sense' needs to be consciously considered and validated before it becomes common sense <em>to you</em>. So in that regard, since it's so obvious already, I doubt the author had you in mind when he wrote the article :)
> I always cringe a little when I read medical conclusions in the mainstream media.

I usually do too, especially articles about nutrition which are notoriously unreliable due to the near complete lack of randomized, controlled, prospective studies and the abundance of observational studies, but this one doesn't seem too bad. In fact, the same author published a similar article in Science last millennium http://www.stat.berkeley.edu/users/rice/Stat2/salt.html so I don't think you can blame the mainstream media too much here if they're just printing an article similar to what would satisfy Science's editorial standards.
This calculus denies any value that may accrue from legal precedent.
So are you calling standardized tests "book learning" or "hands-on"??? I say these things devalue "book learning" as much as they devalue building things.

I would agree kids should be reading books, writing essays, writing math proofs and building robot but not doing (and endlessly preparing for) standardized tests. Comprehension isn't going to ever be fully exercised by multiple choice questions.

Seriously, the problems with standardized tests just don't allow them to be glossed over as "book learning" or any other way. The worst problem of standardized tests is they reduce teachers to proctors and game-strategists rather than demanding they have constructive engagement with their students.

I've rejected papers for bad English, but not because I assume sloppy language will result in sloppy research. Rather, I'm reviewing for conferences which don't have a "major revision" option, and I have to assume that accepted papers will not be heavily revised. So if the submitted paper has language that is sloppy and hard to understand, then I assume the published paper would be the same. And that's not acceptable, because no one benefits from a paper which is hard to understand because of its presentation (not its content).
Thanks for the references.

1. Both 3D printing and CNC are limited in my opinion, (having taught masters students on the subject) it is the job of designers to test those limits, but many things can be done in CNC machining that 3D printing is not capable of and vice versa.

Example this chair I just made (designed by Phil Seaton.) http://www.fabsie.com/blog/2012/03/04/scissor-chair-phil-sea...

2. Tooling cost of switching tools is only zero because you on about using one tool to 3D print. Could speak about various aperatures of tools of 3D printing various types of plastic to chocolate to ceramic. The main reason you change tool sizes is to increase speed, i.e. bigger router bits cut faster and you don't want to spend 3 hours to do something with a 3mm bit that can be done in 12.5 minutes with a 20mm bit. (opportunity for 3D printing to grow.

3. CAD Software is ubiquitous.
The tricky thing about wood is that it's carbon neutral but still (often) a bad material to use.

It's carbon neutral because when you burn it, all the CO2 released from the combustion reaction originally came from the air. But it's often a bad material to use because many forests aren't harvested in a sustainable manner. The situation is better in Europe and North America, but in many parts of the world, far more trees are cut down than are planted which is clearly a bad thing. Using it as a building material is certainly a good "sequestration" technique.
there's a chance that despite blood pressure reductions a low salt diet could cause problems

For that matter, there's a chance that because of blood pressure reductions, a low salt diet could cause problems -- if the kidneys respond to low blood pressure by secreting renin, and renin causes more cardiovascular damage than high blood pressure.

As the director of an engineering team myself, this is an extremely insightful article.

Bossing people around and utilizing extreme micromanagement might work in retail (though, honestly, I doubt it), but being a drill sergeant is not the way to get things done with very intelligent and headstrong individuals in a technical capacity.

The trick of excellent technical management, to me, is the ability to balance the business requirements of management with the technical passions of the engineers. If this balance is off in either direction, the company as a whole suffers greatly.

Engineers need to be intellectually engaged, and need to feel that they can make decisions for themselves (even if it's just within the code base). At the same time, products and services need to ship to keep everyone employed.

It's a tough but rewarding job.

"...we are a species who's evolution has made us so that we crave foods that are actually killing us."

"...it sets up a health amount of skepticism towards the idea that our innate cravings are in fact harmful."

It's modern processed food that's harmful.

We evolved to cope with the amount of salt, sugar, carbohydrates etc. that was readily available to our ancestors on a hunter-gatherer diet (we would've reached an evolutionary dead end otherwise if our "innate cravings" were not useful to us in a survival sense) - you would have to do a lot of hunting and gathering to get the amount of salt, sugar, saturated fat etc that a single fast food meal provides - it was relatively rarer so we have cravings to ensure we got enough of them back when they were scarce.

Evolution is a very slow process. Adding syrup to carbonated water, advertising the crap out of it and selling it at huge markup (coca-cola) can happen over the course of a single human's lifespan.
