I think it would be even more user friendly if you included a more readable expiration. Something like "this link will expire in 2 days (8/19/2011 10:29:11 PM EST)". This gives the user a more understandable deadline, without having to check the current date
I'd argue that the reason why you need to work long hours in a new business is because generally, people who start new businesses are incompetent.

Say what you want about the drive and determination of a bunch of 19-year-olds going through YC, but what they are not is competent. In fact, almost anyone, no matter their age and experience, is utterly incompetent at running their own business when they first get started.

I think your problem is that you're taking "incompetent" as a personal insult (not sure why you're doing that..) when it's meant as a statement of fact. I was certainly utterly incompetent when I started my first two businesses - and in fact I am still somewhat incompetent, as exemplified by the fact that I do need to work evenings and weekends every once in a while.

Show HN: learning three.js or WebGL for dummies
It's my understanding that when people say "working hard" in these discussions, they aren't comparing 25 hrs/week vs. 50 hrs/week. They're usually comparing 50 hrs/week vs. 75 hrs/week.

If I forked my life into a version of me that worked 50 hour work weeks and one that worked 75 hour work weeks, the 50-hour me would win, hands down. The 75 hour work week me would outright miss most of the key strategic decisions that got me where I am. When I look at everything I've done that in hindsight has been a huge career boost - getting involved in the Harry Potter fandom, making friends on the C2 Wiki that got me a job in financial software, learning Lisp & functional programming, founding a startup, and getting a job at Google - they all happened in the downtime between work. Had I simply worked 75 hour work weeks since 2001, I would be a physics grad student right now, hating it, and making a pittance. I'd probably be a damned good physics grad student, but that doesn't help me very much.

Now, I also put in quite a few hours into developing skills and building a track record, and I don't think those opportunities would've opened up if I hadn't. But I wouldn't have thought to look for the opportunities if I did nothing but concentrate on work. You're a big fan of necessary but not sufficient conditions, right? The work is necessary, but so is the downtime.
But I'm wondering, does increasing the work factor actually make the algorithm stronger?

Yeah, that's a bit fishy. Without an explanation, I'm skeptical that the Fibonacci sequence is actually important. Perhaps any branching arrangement of solar panels performs better than a flat one.

Broadly speaking ...

If leaves are space a rational number divisor a/b of 360 degrees around a trunk, then after b turns, leaves will directly shadow each other. To avoid this you need the amount of turn between leaves to be as difficult as possible to approximate by a rational number.

Using continued fractions we can see that the most difficult rational to approximate is

1 + 1/(1 + 1/(1 + 1/(...)))

which is (1+sqrt(5))/2 which is the Golden Ratio.

You can also get better packings by using the Fibonacci Spiral, which again gives the Golden Ratio:

The kid's own article is great. He explains all the steps he went through and the things he learned along the way. He learned about history, biology, the scientific method while doing something that interested him. Props to his parents and/or teachers who stimulated him to go through with this.

I don't think his 'invention' is that revolutionary. If you don't want your solar panels to overlap, it makes sense to choose step sizes that are coprime (which consecutive fibonacci numbers are). I don't think the invention matters that much here though. Aidan is obviously a bright kid and I'm sure he'll go on to do interesting things.

Was it worth it for Microsoft, though? Their entertainment unit made 32 million dollars in profit last quarter – a quarter which they considered an immense success. With that kind of income, the project will never break even, never mind turn an overall profit. Even if you consider intangibles like strengthening the Windows platform, it's hard for me to believe that those billions were best invested into Xbox.
> Say we fork the universe now and one version of you works 25 hour weeks henceforth, which the other works 50 hours per week henceforth. Who retires with more money and more impact on the world? Both version of you are equally smart. The well-rested you might make SLIGHTLY smarter decisions due to happiness/lack of fatigue perhaps... But surely you wouldn't contend that the success outcomes (professional impact and wealth, for the sake of argument) wouldn't be different.

It's hard to tell. Would I work better and smarter knowing that I only have a slim 5 hours a day to get stuff done? I think it may have more positive effects than you think - particularly if the rest of the time was doing things that will restore my energy (e.g. cultural activities, meeting people, sports, relaxing...)

Sure, YC encourages a kind of work-work-work attitude, and I'm not suggesting this necessarily will hurt you - in fact, because every YC founder is basically completely incompetent (at the beginning) and thrown into a maelstrom of challenges, it's not that surprising that there's a culture of working long hours to make up for lack of initial competence. But to suggest that somehow the eventual success comes because of the long hours (rather than because of the connections and wisdoms imparted by YC, as well as the fact that all or most YC founders are very smart) seems a bit confused to me...

But at least you have actual steakhouses as opposed to pretend steakhouses that don't understand what "rare" means (most places will deliver a medium, medium-rare if you're lucky), and believe a steak should be seared enough on a charcoal grill to taste like coal. And those are the good ones in the UK.

UK "steakhouses" make me grumpy.

My local pub is actually the only place I've found that does a tolerable steak. What I'd expect at a cheap roadside diner in the US. Certainly not a big treat, but at least edible. Everyone I know in London that's been there that haven't had steaks outside the UK have hailed it as having the best steaks they've ever had. To everyone else it's ok in a pinch but nothing more. To me that says it all.

Sorry - it's a sore subject, I absolutely love steaks.

FWIW I'd stay focused on the core concept (scanning many papers quickly), this is genuinely useful. Nail that first before moving on to other features.

"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."

Except it's trivially impossible to generate more energy like this (as he claims)! If a set of solar panels is independent and non-interacting (e.g., they don't shade or heat each other), then their total power output is simply the sum of their individual power outputs. And so their total energy outputs (integrated power) is the sum of their individual energy outputs. (Necessary distinction because their power peaks may occur at different times).

P_tot = Σ P_i

∫ P_tot dt = ∫ (Σ P_i) dt = Σ (∫ P_i dt)

E_tot = Σ E_i

If there is an unqiue optimal orientation for a single static panel (which under realistic assumptions there is) -- optimal in terms of maximizing energy output, E -- then the optimal orientation of a array of independent solar panels is just the same orientation, iterated. Combine inferior panel orientations, and their total remains inferior.

E_i < E_opt (for i <- 1..N)

Σ E_i < N * E_opt

And all those panel angles in his "tree", facing non-South, up, down, towards a wall... they are individually inferior to the single 45° south-facing panel in his static array. So combined together they are still inferior.

Where did his experiment go wrong? I'd start with the shade issue. The whole setup is in intermittent shade (note the tree shadows); and one experiment is sitting near the ground, the other is mounted on a pole. Looks like different shade environments. His output graphs show that the entire flat array is sometimes in total shade, at a time when the pole-mounted "tree" is not:

http://www.amnh.org/nationalcenter/youngnaturalistawards/201...

Another fatal flaw (I had to look this up to check) is that he is measuring voltage, not power, and they are not linearly related in photovoltaics. Actually, the open-circuit voltage (what you get if you stick a voltmeter over a solar cell, when it's not hooked up to a load) is practically independent of irradiance:

http://i.imgur.com/SWGjV.png

This from the solar module datasheet here:

http://www.bpsolar.us/products/3-series-solar-panels-polycry...

Open-circuit voltage going from 200 W/m^2 to 1,000 W/m^2 only increases from 34 V to 38 V. Power output, with a real load, would go up by about 5 times.

So, he never really measured energy production, or anything that remotely approximates it.
That is something I've noticed too. Not a single one of the highly successful people I know is one-dimensional. They're all well-rounded human beings who spend time indulging whatever passions they have.

The only ones I know who are slightly less well-rounded but still successful, as I mentioned in another comment, are the corporate successful types - imho because they have less of a choice about how to manage their time.

I found this one extremely thin.

There's a title that says we're "hard-wired" for rc. Then makes claim that our aversion to corners is a result of socialisation (i.e. not hard-wired). The case is simply ridiculous. Do parents not mind when we play with jelly-fish, but get upset when we eat sandwiches? Do schools round the corners on textbooks lest children suffer physical or emotional damage from those nasty sharp corners?

There's no substance here, just vague claims and circular citations.
Interestingly I never found playing the cello exhausting - well, very occasionally if I had been playing a lot (several days running of a couple of hours practise, many hours rehearsing, couple of hours performing). On the other side, singing could be very tiring (though again, all-day sessions, always standing up).

I've noticed that Florian Muller is more skilled at covering his own behind, rather than predicting patent litigation outcomes.

Every prediction he makes is hedged with a statement about how the alternate outcome is possible "even though many don't believe it's likely". Whatever his preferred outcome, he will make the stronger case for that.

It's not about ability, it's a cogent choice to step back and not play into the arms race. They did the exact same thing with the DS, and outsold the (very significantly) more powerful PSP almost 3:1. And a few years earlier, the GameBoy brutalized the Game Gear.

In terms of raw power, the GC was the most powerful console of its generation (or tied with the Xbox). So was the N64. Neither panned out (though neither lost N money either), so Nintendo went into a different direction. And — at least for a time — struck gold.

As long as caching exists, there will always be tricks like this. Here's another example: Encode a unique ID in an image and send that to the browser with a long cache time. Then on subsequent requests, use JavaScript canvas to read the image and decode the unique ID from it.

I've already completely disabled disk caching in Firefox by setting browser.cache.disk.enable to false. I'm seriously considering disabling the in memory cache too at browser.cache.memory.enable.

EDIT: In fact, I've just gone and disabled in memory caching. Will be interesting to see if this change is noticable in my normal usage.

I assume when you say incompetent, you mean lacking in experience. That is correct, and often unavoidably so. Unfortunately, incompetent is typically used in a far more derogatory manner by most. Thus, I fear most people reading your post will take as a synonym for stupid.

But even with that clarified, I'll still disagree. The first 3-6 months of starting a business often involves a lot of busy work. This is not coding or otherwise requiring of immense thought, but it does take time. A great many business owners have said that it requires long hours to get a business up and running.

Of course, that does not apply to regular employees. Nor should it remain constant after you've started. Even so, heads of companies often do spend longer hours working than most. That's not to say their lives are unbalanced. Let me quote Bill Gates:

http://money.cnn.com/2006/03/30/news/newsmakers/gates_howiwo...

* It's a nice luxury to get some time to go write up my thoughts or follow up on meetings during the day. But sometimes that doesn't happen. So then it's great after the kids go to bed to be able to just sit at home and go through whatever e-mail I didn't get to. If the entire week is very busy, it's the weekend when I'll send the long, thoughtful pieces of e-mail. When people come in Monday morning, they'll see that I've been quite busy— they'll have a lot of e-mail.*

Working long hours is not always a sign of incompetence or lack of process. It still depends on the situation, and what you do in those hours. I do agree with a weaker statement, it shouldn't be that the majority of your employees always have to work long hours.

SAMSUNG and Intrinsity Jointly Develop the World's Fastest ARM® Cortex™-A8 Processor Based Mobile Core

http://www.samsung.com/global/business/semiconductor/newsVie...

"Seoul, Korea, Austin, Texas - July 27, 2009 : Samsung and Intrinsity today jointly announced the industry's fastest mobile processor core implementation of the dual-issue ARM® Cortex™-A8 processor architecture in 45 nanometer (nm) Low Power (LP), low leakage process technology. This Cortex-A8 implementation, code-named Hummingbird, delivers 2000DMIPS at 1GHz. The Hummingbird comes with 32KB each of data and instruction caches, an L2 cache, the size of which can be customized, and an ARM® NEON™ multi-media extension. Performance and power consumption of the Hummingbird have been validated in silicon. Samsung is currently developing standard mobile SoC products using this new core."

Maybe you still run into one fundamental problem or two where you need to read something hard.
But otherwise, the "how to learn" thing is more obsolete than the other things claimed.
