Well said. Silicon Valley has created this perception that everyone should be trying to go for the next big blockbuster... of course, that what the VC community would like everyone to do. Because they can only make money on blockbusters - they can't make money on the scale or time horizons of a more modest growth business.

Don't believe the hype.
No?

Well, it'll certainly get them closer.

This was a big shock to me when I moved from NYC to Chicago. Stores in NYC actually stock things I want to buy, and the employees actually care about their customers. It's very, very strange.

(My first experience was buying shoes from the Asics store. I walked in, asked for a Gel Evolution 6 in size 11 2E, and they had it in stock. Never in my life have I been able to buy shoes at a store...)
I thought of a question from one of the threads I'm in for this article. If Google is sending different people with the same search query to different pages doesn't that reduce the value of being highly relevant on a topic?

Yahoo Stores was Via Web which was built by pg.

There's a thread in some of the joelonsoftware discussion forums where Joel argues that pg's use of continuation-style passing and closures to represent web state made it difficult to use the back button and that it was the wrong thing to do. If I recall, pg also replied on that thread defending his decision.

What should Women Eat During Pregnancy
Pregnancy is one of the most beautiful phases of a woman’s life. It garners moments that are often cherished and remembered fondly in the years to come. However, this same period is probably the time that demands utmost attention to be taken on the part of the mother and of course the family members.

If you want to see how consumer electronics can still be sold in retail locations, just spend ten minutes in an Apple store. They are selling some of the same products as Best Buy, but the two experiences couldn’t be more different.

I think the comparison to the Apple Store is unfair. Apple doesn't have to compete on price. A MacBook Pro costs the same regardless of where one purchases it and so Apple can create a store that's a joy to be in and know that customers will purchase there. If you're going to be paying the same price, why not shop where the experience is the best.

On the other hand, most of what Best Buy sells can be bought in a competitive market. If I go to Best Buy to buy an Asus computer, I might find better prices elsewhere. I'm going to buy it at Best Buy if they have the lowest price. As such, if Best Buy spends money to make that experience of buying an Asus a joy and has to charge a bit more because of it, I might browse there and buy elsewhere.

It's Apple's tight control of the pricing of their products that allows the Apple Store to be a viable business model. Apple doesn't have to worry about MacMall or Target or Best Buy undercutting them.* They don't have to worry about a customer asking their trained staff all of the questions and then going to Best Buy to actually make the purchase. Best Buy does need to worry about that on the majority of their products. If Best Buy puts money into smart staff members to explain my different laptop options, I can easily go elsewhere to make the purchase cheaper should those staff costs appear in the price.

It's a lot easier to provide a great experience when you don't have to compete on price.

*Yes, Amazon and B&H do offer discounts on Apple computers, but those discounts are usually small compared to the overall price and small compared to the variation in PC pricing.
A framework for life goals
Not sure. We submitted before 8, but the resubmit link was available well past 8 (and still is now 2 hours later). I guess the safest approach would be not to touch the application after the deadline, but if something's missing in there, it might be worth the risk.
I buy that information gain is the same as the optimal strategy, so long as you are taking into account your opponent's optimal strategy with a weighted probability distribution.

The unexpected hanging paradox is a great link, thanks :) awesomely enough though, game theory handles this problem! This is the "why" behind minimax. If John Nash were sentenced by that judge, Nash would decide what day to expect by flipping a coin, and the judge would segfault :p

To answer your question though, if there are multiple paths to the same words (eg Tree(1) leads to Union(a,b), Tree(2) leads to Union(b,c), and Tree(3) leads to Union(a,c)), that surprisingly doesn't make the solution any harder... though my links above aren't particularly useful for it.

To find the optimal strategy for the player choosing the word: for every possible set of words (so all 2^words-1 options), calculate what the optimal strategy would be for your opponent if they were playing against someone picking randomly from that group, and then choose the group causing the lowest expected value for your opponent.

Make sense? [edit: NO! I didn't show that optimal would necessarily come from a uniform random selection from the word bag... and a proof doesn't jump to mind, though my intuition tells me so]

[edit 2: YES! Just assume that the strategy doesn't need to be uniform [though I still maintain it will be], and use gradient descent to find the optimal weighting]

Before working online I was a manager in a specialty outdoor retail store. I spent a lot of time talking outdoor tech with company reps.

Gore-Tex is not the most expensive because it is the most breathable fabric. There are plenty of others out there that are more breathable--heck Lowe Alpine was beating Gore-Tex breathability with their Triple Point Ceramic coating 15 years ago.

Gore-Tex is the most expensive because they pay attention to ALL the details.

For instance, as a membrane, Gore-Tex has to be glued to its face fabric. Coatings like polyurethane do not; they self-adhere. The type of glue, and how it is applied, makes a huge difference in the durability of a membrane-based waterproof fabric. Gore spends a ton of time and money on R&D around the gluing, which is why Gore garment manufactures must use Gore-approved seam taping machines. It's also why Gore can guarantee the fabric for life directly to the consumer.

Gore also reviews and tests the design of every single piece of clothing or footwear that ships with the Gore-Tex hang tag. Every company who makes a Gore-Tex jacket must send copies of it to Gore, where it gets tested in rain chambers etc. If it does not past muster, the manufacturer has to make changes until it does. As you might imagine, this adds cost. But it also makes sure quality is high.

Wasn't good enough for the Ariane V launch.
I don't think I agree that slower growth due to closing stores necessarily leads investors to sell the stock. A typical metric in retail is same-store-sales. If you close a BB store that is in close proximity to another BB store, its possible (probable?) that the surviving store could see a jump in same-store-sales. Investors may see this as a good thing.
You sound like a mercenary, which is fine for those without viable options.

However, the article is saying the chances of success is higher if you find someone who also believes in the vision.

Ask HN: Idea for the most fuel efficient gas car. Will it work?
Short version: Give enough lift with magnetic strips under the road to reduce car weight.

Long version:
Here is the most practical way to get the best mileage out of existing gas car. Everyone knows most of the fuel spend in today's car is for dragging the metal around. What if we use magnets (strips under the road and bottom of the car) to give enough lift so the car can go longer distance for the same amount of fuel. I am not talking about lifting off the ground, but just enough to reduce the burden on the wheels and the car is driven the usual way.

Will it work ?
Great in a way that it costs more money to produce a penny than what it's worth.

Since Udacity is not exactly forthcoming on exactly what their business model will be, could you add some insight to exactly what the great business model is? Right now, I see the MITx and Stanford programs being a small loss per student compared to the normal amount universities spend on instruction, but a small loss a hundred thousand times over doesn't exactly turn a profit.

If you are going the freemium route (free content, pay for testing/credentialing) you have the classic freemium dilemma, what is your conversion percentage from free to paid and what is your margin on the paid version. If you anchor your product pricing at zero, you can't exactly charge hundreds or thousands for testing. Plus, the vast majority of students in the Stanford experiment were overseas which makes the paid option at a recognized testing center much more difficult.

It's all a percentage game. Revenue = Total Students * percent who complete the class * percent who can pay for testing * percent who do pay for testing * margin on testing. We ran the numbers in a number of different number of scenarios when we looked at going that exact same route and found time and time again that even if you can break even at a small number of very popular classes, the chances of being able to build out a broad curriculum of classes with less mass appeal was not good.

To use some realistic numbers, let's take the Intro to Databases class and make up some inputs:

Number of students: 90,000

Percent who completed the class: 7.2%

Percent who could take tests at approved centers: est 40%

Percent conversion from free to paid: Classic freemium less than 5%. Hugely optimistic: 20%

Margin from a paid testing center: $10-$50 (est)

90,000 * .072 * .4 * .05/.2 = 130/520 estimated paid students

So, we have a probable range of $1,300 - $26,000 based on some real numbers and some educated guesses. $26,000 may sound like a lot, but that amount can easily be absorbed just in the professors time prepping and managing the class. Now add on the rest of the overhead of high paid SV engineers, offices, support, etc...

The end result, an enormous amount of things have to go just right in order to cover your base costs. Even if those things go just right, you still have a huge amount of pressure to create classes with the broadest possible appeal with the highest possible number of students completing the course (in order to have a chance of testing revenue). Those market pressures do not coexist well with academic integrity and high standards. They also don't support classes that might "only" have a few thousand students.

There other ways to get to free education for all (we're on that path ourselves), but starting out as free without the backing of a large university is a tough proposition.
Excellent science, and excellent science writing.

He brought this up on Dev Days too (2009?) and made a jab at the lisp backend not knowing how to handle the back button. It's sort of low to keep hearkening back to the same usability mishap.

This is a non-story.
Given your perception can generally fill in the vowels - picking any early on would seem non-optimal.
From working at Best Buy during college, a major part of their problem was the independence of the local management.

HQ would pass down all these lovely plans they spent millions to develop and test, then there was no real follow through. Store management just did whatever they wanted anyway.

We'd spend all this time at Saturday morning meetings learning about our new initiatives; how to relate to the customer and make recommendations instead of selling.

Then come monday it was back to the same thing we were doing before we wasted 300 hours of labor learning about some already forgotten scheme.

Another huge problem was they way they promote. Supervisors and managers were almost universally promoted completely based on sales ability.

For some reason they couldn't quite figure out that sales ability and management are two completely unrelated skills.
It would appear that way.

Why are you dredging up a ten-year-old non-controversy?

That may be true - but that's little comfort to the end consumer, and earns you no points next time they find themselves in a store picking out a new phone.

I don't understand why Google doesn't support offline/non-OTA patches. Apple achieved phenomenal adoption speed for new releases pre-OTA, there's no reason Google can't do the same. The fact that Google needs a carrier's blessing to patch phones is a non sequitor.

How many good 'Hacker' movies have there been?

Better yet, has there been any good hacker movies, ever?

The only movie I liked wasn't remotely "hacking" was the first Matrix. It was mostly some pop terminology sprinkled through it. Much like all Hollywood interpretations of what hackers actually do.

It's hilariously actually.... Spinning 3D cubes to hack into some database, while the actor looks like he's playing an awesome game of minesweeper on flaming tits that emit crummy (inappropriate) pop music.

I'm in my mid-twenties, and was seriously considering it when I thought it was reliably reversible. My reading at the time indicated that this wasn't the case and there was a good chance that you'd stay sterile after reversing the operation.

If the polygon is self-intersecting, the area around which the algorithm traverses the edges clockwise will be subtracted from the rest of the area traversed counter-clockwise. While interesting, I have yet to find this fact actually useful.

Edit: for more fun with polygons, check out Pick's theorem [1].

Since I'm guessing that pretty much everyone on this site has a copy of CLRS, the Selected Topics chapter on Computational Geometry has a good overview of cross product tricks. The convex hull algorithms are also interesting, useful, and very simple to learn.

If you're finished with that and are actually still interested, look at the Rotating Calipers method. It's a way of addressing all antipodal pairs of a given polygon, which serves as the basis for a whole whack of algorithms. Example - finding the narrowest rotation of a polygon. Some of you may recognize this as the solution to the last (and easiest) problem at the 2011 ICPC world finals [2].

The SNES sound hardware was a little bit more complicated than that.

It has a control CPU, and it's own RAM, with no access to the contents of the cartridge, or to main RAM. Obviously, you have to emulate all of that accurately, or the code that controls the sound output might not work correctly.

The actual hardware is more complicated than just a sample mixer. It's implemented as a custom DSP, which does sample decompression, high quality resampling, mixing, has an envelope generator, several effects (programmable FIR filter, echo, panning), and a noise generator.

Older SNES emulators didn't really emulate any of this. They treated it as if it were a simple sample playback device. This worked OK for most games, because they didn't use those features. However, when a game actually used those features, everything sounded wrong.

Later, they started supporting the effects, but nobody understood how the DSP was actually implementing those effects, so they didn't sound quite right. They just implemented stuff that sounded about right on the games they were testing on. Reverse-engineering all the hardware, so this stuff could be emulated accurately, took a very long time.

Right now, the SNES audio hardware is completely understood. We have several emulators that are perfectly accurate, both in terms of timing, and output. For example:

http://www.slack.net/~ant/libs/audio.html#snes_spc

Both ZSNES and bsnes use that library, and I believe that Snes9x is nearly as accurate now.

That said, I don't think anyone's actually dumped the DSP's program code.

Edison: Never waste time inventing things that people would not want to buy
Bearings are already quite good. You could get the same result by using magnetic, no contact wheel bearings at a very large increase in cost, but the fuel economy improvement would be tiny.

The big problem is not rolling resistance, its wind resistance. Wind resistance goes up by the square of the velocity increase....double the speed and you quadruple wind resistance. The second biggest fuel consumer is the mass itself (not the weight). Accelerating and decelerating mass requires energy. Magnets might make less "weight" but they would make more mass.
