I'm in Japan now and Japan is still like this. Actually, a lot of SE Asia is like this - Korea, HK. When I talk to people about this they even admit it. They realise they are goofing off a lot of the day because they know they have to stay late so there is little incentive to be productive.

I believe that people can only work productively for a set amount per day and keeping people at work after that doesn't lead to any more work being done.

One of the worst articles I've ever seen posted on HN. I'm not going to even read through the comments, but I hope most are simply stating that this is complete BS. Otherwise, you're arguing simply for the sake of arguing. Not everything should be argued, not everything should be over-analyzed. Working long hours is often a choice; you do it to get ahead, you do it to improve your product, you do it for any number of reasons (and yes, maybe you do it because something is broken). Any argument to the contrary supporting this stupid argument is simply BS.

Ensuring that if-modified-since is a proper date might not help much there. The evil site could just encode the unique id info in the time (and/or date) portion of the tag. A possible workaround would be for the browser to randomly send time a few seconds in the past, so the cache still mostly works, but that the value can't be reliably used for anything else.

Agreed. The post offered at least one way to think about what you want to do in life. I for one don't have a clue about what I would most like to do. I do have a sense that my current job isn't it. But I think it would be foolish to search for a new job or just quit before knowing what the goal is.
The best introduction to Calculus is classic "Calculus Made Easy" by Silvanus P. Thompson. It is in public domain, is a de-facto standard and is praised by many working scientists (Antony Zee, for example).

The book itself
http://djm.cc/library/Calculus_Made_Easy_Thompson.pdf

Wikipedia:
http://en.wikipedia.org/wiki/Calculus_Made_Easy

It gives you a working knowledge to get going with almost any practical problem you may encounter that needs to be approached with mahtematical analysis.

I would say that Spivak books are more about learning the culture of working mathematicians, and while with its merits one must be careful with commitment of investing her personal time to it.

Also, here is a great page to learn about good (and usually public) books for different branches of mathematics and physics by a Nobel-winning theoretical physicist G. t'Hooft

Interesting, but I think there are some good comments (at the article) too -- pointing out that it also just seems to make sense -- like,

Undergraduates write to professors with singular first person pronouns because they are often requesting information, or this sort of thing... understandable then that there's less reason for I, me, and my in the professor's response (and easy to imagine similar situation in other relationships).

Still, a cool article. Interesting research.
My bet is, that the tablet sales will be good in terms of absolute numbers, but not as high the industry had wished.

I still do not see the too many compelling usecases when comparing a tablet with a smartphone + netbook/ultra leight weight laptop.

Hence the hugh success of the Ipad is in my opinion not much a result of its advanced features or even its slick design but rather its clever position as a must have status symbol.
That is a surprisingly clever and evil hack.

There is a post on the website that gives back story, but basically, when I first created the site, I would post links to my new articles in my fb statuses (Only did this 2 or 3 times). Other than that, I would message my friends with the link. (Again, I never spammed.. maybe only did this to 10 friends or so..) My site simply has never had enough content to be "spam worthy".. After a month or so, I had to take my site down. It was only after I revived it that I realized that it was suddenly in fb's spam filters.
This is also the major disadvantage for anyone new coming into this space.

Apple got to launch their incomplete-but-solid product and then spend a year or two refining it and incrementally adding features. That's the advantage of redefining/creating the market you launch in though, it doesn't extend to anyone else.

For anyone trying to compete with them now, they have to hit the ground running with a comparable-or-better feature set (which I assume is why Android vendors make so much fuss about Flash) _and_ comparable polish.

I think you're both saying the same thing, the parent just worded it a bit oddly.
The comparison is against a flat row of cells that do not track the sun. I suspect that it will not do better compared to an array of cells that do track the sun.

Basically the tree of cells are arranged in different angles so that as the sun moves some of them will always be receiving optimal sunlight when their normal is parallel with that of the incident light.

Very nice insight, especially for a kid his age. I certainly would not have thought of it.
Agreed on the formatting, but I bet that having that expiration date on there increases the CTR.

Question: Does his tree have nearly double the number of panels? If so, does that have anything to do with him getting more power?

Using the imperative wording "please confirm" suggests the recipient must take an action, rather than passively receive information. This reminds me of a Mac OS X Human Interface Guideline:

"Use a verb or verb phrase for the title of a push button. The title you create should describe the action the button performs—Save, Close, Print, Delete, Change Password, and so on."

The difference between "Email confirmation" and "Please confirm your email" is like that between "Ok" and "Save."

The extension requests permission to access "Your data on all websites" and "Your tabs and browsing activity". I guess what I'm saying is that there should be a distinction between permissions for accessing stuff in the browser and accessing external data through AJAX and other resource requests. Besides cutting off extensions themselves from the outside world, Chrome would just have to prevent extensions from injecting scripts or elements that made external requests into loaded pages by disallowing <script>, onclick='', src='' etc... from being added to the HTML and DOM of those pages.
A couple of points:

1. Like others said this is in comparison to a flat non tracking solar panel, the tree configuration would lose out significantly against a tracking panel.

2. Fairly disingenuous graph on the second page, but then again professionals in business and science do this all the time as well.

3. With the current state of solar technology this patent is useless. But if someone invents solar cells who are so cheap that they cost less than the solar tracking equipment, this could become quite a lucrative patent.

4. I wasn't aware you could patent things which are this directly copied from nature. I was under the impression that you could say patent a mechanism which emulates the motion of a specific fish but not the motion itself, or can you ?
I wonder if some genetic algorithm style testing of angles and placements could yield even more efficiency?

Seems possible that nature hasn't yet hit optimal design in this area.
6.8 magnitude earthquake hits Japan, tsunami advisory in effect
it makes a lot of sense, nature has been doing it for a lot of time :), I hope that other scientists elsewhere can also confirm that the improvements are so dramatic, I mean, having still/motionless cheap arrays that can perform 20%-50% better than the flat ones are great news!
Probably not, but I would have to say, THIS is the kind of stuff we should be awarding US patents to...
ITunes Connect: New Features for Apps Now Available
We are pleased to announce the following new features to help manage your apps on iTunes Connect.

“Metadata Rejected” Added to App Review Status. You can now resolve metadata issues that have been identified by the App Review team without having to recompile and resubmit a new binary for review.
If you submit an app and the App Review team determines that any metadata items are not compliant with our guidelines, your app status will change from In Review to Metadata Rejected. Metadata items include your app name, keywords, rating, or category. Screenshots and icon images are also considered part of a metadata rejection if they are determined to violate the App Store Review Guidelines. Rejection details for apps with the Metadata Rejected status will be available in the Resolution Center.

To resolve an issue, you will need to edit the metadata in iTunes Connect. Your existing binary will then be reused for the review process.

Bundle ID Is Now Editable Before Binary Submission. If you have not submitted a binary for review, and your app is not using Game Center or the iAd Network, you will now be able to edit your app's assigned Bundle ID in iTunes Connect.
To change your app's Bundle ID, click Edit next to your Bundle ID in the Manage Your Applications module.

Now I don't disagree that an array of cells that track the sun would produce better results, but it would be fair to assume that this would cost energy.

Keeping that in mind, do you think it would still provide better results?
Last paragraph sums up the possible advantages-

Aidan wrote: "The tree design takes up less room than flat-panel arrays and works in spots that don't have a full southern view. It collects more sunlight in winter. Shade and bad weather like snow don't hurt it because the panels are not flat. It even looks nicer because it looks like a tree. A design like this may work better in urban areas where space and direct sunlight can be hard to find."

Exactly. Very few of these people will actually listen to the first lecture, and very few of those people will put in the work to complete the course and master the material.

Very true. That is a huge advantage if space is a concern.
Nintendo will have to have a string of spectacular failures before it starts share cropping. Remember n64? Remember GameCube? Both were pretty lackluster compared to Super NES. VirtualBoy? Disaster.

The Wii U and 3DS might be disappointing, but Nintendo is a survivor. It has the internal support to last through dry spells on the strength of first party titles alone.

It would be very difficult for a company as resilient and conservative as Nintendo to sink itself in such a short time frame. Remember, too, this company also started off making playing cards 100 years ago.

The only bad end I could see in Nintendo's immediate future would be an aggressive if not hostile takeover. I believe its market cap is only $20 billion, and supposedly half of that is in cash. If Apple or Microsoft wanted to pay a premium for the ultimate maker of killer apps this is the time to make a move. In another cycle it will be too late: the mobile wars will be decided and/or Nintendo will likely have recovered. Who knows how well the company would survive a takeover though.

Space Station Hotel Operational by 2016
Microsoft aren't opposed to _all_ free software licenses. They've been rather fond of BSD licensed software from the get-go (it was used and may still appear among copyright credits in Windows).

The GPL is another matter.

Though in recent kernels, Microsoft have contributed more than Google have.
The plugin mentioned at the end won't work - not unless it's going to have a tedious whitelist.

Since many sites use "3rd party requests" like remotely hosted images, fonts, and even for example google based jquery, blocking them would most certainly break the page.

What I would like is a warning when the last-modified appears to be a malformed date or not a date at all. PHP's strtotime can convert almost anything to a date/time (if it really is a date). Can it be ported? Optionally when it doesn't appear to be a date within the past 30 days, never cache it.

Another solution for a pure privacy mode is to never send back last-modified, ever. It would hurt servers and page load times because things would never be cached and always served as "200" instead of "304" but for a pure privacy mode, may be necessary.

Last but not least, we could just dial down our cache time limit to say an hour max. It would still give some info to the trackers but not between browser sessions or the computer turned off. Since firefox doesn't have a time limit on the cache, using a memory-only cache is the only easy workaround for now.
I'm not an expert here, but it's pointless to make tracking sun panels that costs a lot more if the outcome wasn't that great, I bet tracking sunlight is still more efficient even after spending energy to move the panels, it makes no sense otherwise. The real benefit of this is that you get a cheap motionless panel that performs a lot better than the flat version, this is specially important in places like Africa where you need to be as efficient and cost effective as possible.

According to Wikipedia (http://en.wikipedia.org/wiki/Photovoltaic_system#Tracking_th...):

"tracking systems can increase viable output by up to 100%...For large systems, the energy gained by using tracking systems outweighs the added complexity (trackers can increase efficiency by 30% or more)"

The new tree design can make 20%-50% more electricity. Wouldn't know till they do some legitimate tests but it seems like the sun trackers fare better.
