Clearly there is a distribution challenge (high transportation / storage costs) but I like the idea of disrupting them.
I don't think he formally uses big-O but understands if something he is writing is linear (iterating over an array), exponential or O(1).

People have to get rid of their big hard on for Big-O, a useful concept that takes a couple hours to learn. It isn't a difficult thing that only the true macho programmers can know. I'd wish it was traditionally in starting programming books in the 'optimization & profiling' chapter and we wouldn't be having big fights about it.

His AT&T pricing is inaccurate (he is reporting it too low). This looks like a great comparison chart, but the first thing that jumped out at me was the low prices he used for his analysis. After doing my own research it turns out his #'s for w/1 phone is wrong, w/2 phones it's even more wrong, etc.
No. There shouldn't be a Warby Parker for Diamonds.

Sure there are services like BlueNile etc but they're nothing like a Warby Parker for Diamonds.

Diamonds are bought, not because of what they are but what they represent.

The whole point of diamonds is to capitalise on what they're representing rather than their actual worth.

Their value is created through the likes of "diamonds are a girl's best friend" which is why the price is high for them.
Hence the advertisements have been developed around the whole perceived value of diamonds ala. "diamond's are a girls best friend" because when you present a woman with a diamond you're presenting her with a promise - a promise that you will look after & take care of her. Which is something that most women want.
Nice little history on Diamonds (and why trying to disrupt that market is incredibly difficult):

ArsTechnica: Real-Time Coverage of iPhone5 Event Generates 13.2 Million Hits
Don't worry, these cameras make millions of dollars in revenue on a yearly basis (55m per year, in the case of D.C.). Oh, sometimes, maybe, depending upon who you ask and which study you are citing, they sometimes reduce accidents by some (usually fairly small) percentage.
I would imagine that you'd have more of a problem finding enough ethernet ports than ip addresses.
One advantage that the eyeglass market has is massive tax favorability in the U.S.

I believe it's still the case that prescription eyeglasses can be bought with pre-tax dollars under a "use it or lose it" flex savings plan. I assume vision plans, which often include large purchase credits for eyeglasses at least biennially, are also tax deductible benefits.

The result is often relatively price-insensitive consumers who "have" to spend $200+ on glasses lest they not be taking full advantage of their benefit.
I saw that as well... 2 and 6 gb. I understood the infographic to mean a base amount of tethering data was free per month, which sure isn't how it looks on Sprint's site.
Absolutely, you would have to get new bedsheets, comforters, and beds to support the new form factor, but if it means replacing the mattress every n*2 years instead of every n, I'll come out ahead in the long term.
But (and someone correct me if I'm wrong), but individual IP addresses are not a commodity. If you broke apart that /8 and auctioned them off, if would be a routing nightmare.
That's nothing compared to the tens of millions of revenue they make.

In the US a speeding fine is likely to be $200 or more if issued by a police officer. Fines from automated cameras are much cheaper and carry less severe penalties both in cost and in consequences to your driving record.
A couple of years ago I was looking for a Tempur-Pedic style mattress, but didn't want to spend thousands for one. After doing a lot of research I found Isoform mattresses. They are only available through the mail and have a 90-day return window if you're not happy. It would be very expensive to ship numerous mattresses, but the trial of one with no commitment to buy is pretty good.
Price, of course, is not a function of the material or technology. From what I hear, these things quickly pay for themselves when placed "strategically" [1].

Sorry Colin, I should have been clearer. What Ken is referring to in the article is very commonly, what anyone who has attempted to optimize their content (typically known as SEO), would go through. He is making the argument that he has made an argument on how to create real content or to quote: "consistently and cost-effectively generate real content".

He then launches into all of the tactics he would employ under the banner of "The Death of SEO" when in fact he is advocating for precisely that: SEO.

I may quite possibly be missing something or not explaining myself and my previous comment. Hope that's not the case.
I used to think the same thing about shoes, but Zappos has managed to crack that with their super-easy returns and two-way shipping.

Is two-way shipping with easy returns possible for mattresses? I would be willing to try it if I never had to deal with a mattress salesman again.

I'm coding a web app in it right now. Go includes a package for its own web server. That's a huge benefit, because it means the app can be state-ful instead of the usual (for Python, PHP etc.) stateless. The former means you can have all the data you want ready to go, in the most efficient memory structure, when the user arrives. Which translates to great performance. For example check out http://langalot.com and somewhat slowly type in "bark".

The OED attests that silverstorm's usage is the older one, predating yours by 8 years (1604 vs 1612).

Regardless (and I feel like such a broken record saying this), meaning in language is determined by consensus, not dictum, and at least for me (a 21 year old who grew up in the United States), "nauseous" can have no meaning but "sickened". "Nauseating" is what I would use for your meaning.
I think they were more pulled in by brand cachet than they were by this marketing specifically.
I also interpreted the infographic to mean that you can tether up to 5GB per month for free, but I think that's incorrect.

Looks like Virgin has announced their pricing for Australia but not for the US: http://www.virginmobile.com.au/iphone

Virgin's iPhone5 will likely remain a better value than any subscription option mentioned in the article. Unfortunately Sprint (and therefore Virgin) can't get close to Verizon's US 4G coverage.

Even more afraid than those of us that keep our networks open.

If you 'close' your network, and somebody does something nasty over it, you have to prove it wasn't you, while if you leave your network open it is obvious that it could have been anyone.

Closing WiFi networks is some of the worst kind of security through obscurity, and from the legal point of view of defending yourself from accusations based on what others do over your network, leaving it open is by far the best option.

It is also much better from a practical point of view, for example, now I hate traveling to Germany because of dumb laws like this and how sheepeshly Germans follow them, the whole country has become a WiFi wasteland, while in Poland you can find open WiFi networks basically anywhere.
No take home tests while you were there fits in with what I infer from this document: http://web.mit.edu/faculty/reports/exam-termregs/report.html

It's a report from their Faculty Policy Committee's Subcommittee on Examination Terms and Regulations, undertaking in 1998. Among the things the report covers is consideration of lifting the ban on take home tests. From the documents they reference, it appears that MIT tried in experiment starting in 1992 to allow take home tests, and discontinued the experiment in 1994.

In that report, they recommend allowing out-of-room exams, where the exam would be given out at 1:30 PM, the students would have until 7:30 pm to turn it in, and the students can take the test where they want. It looks like the main point of this was to make it so students could have access to computers and libraries during these tests.

Their concern with allowing take-home tests seems to be that professors might give monstrous take-home tests that would consume too much time.

Upon further Googling, it sounds like this policy or something similar was adopted and is still in place today: http://web.mit.edu/catalog/overv.chap5.html
Imagine if the cultural norm went from spending a lot on an expensive diamond where the money went to a textbook evil corporation to spending much less on a cheap manufactured diamond of higher quality and donating the difference to the charity of the lady's choice.
There are all sorts of outlets for reasonably priced, what you see is what you get mattresses: Sam's Club. Costco. Ikea. You can get a decent name brand mainstream mattress for ~$500.

The problem with mattresses is that it's a product where you need a salesman. There's a bunch of different products that look similar, but have significant differences. You want to match the customer with what they want (or tell them what they want) so that they don't return the thing.

Plus, there are some inherent logistical differences between a pair of eyeglasses that can be dropped in an envelope and shipped to anywhere in a day or two. Distribution and warehousing is expensive, the product needs to be delivered quickly (and picked up if the customer is displeased).

There is a market for discount mattress sales outlets on the internet -- but just as online furniture and appliance outlets haven't "disrupted" the market, mattresses online are unlikely to either.
Ah, I see what you were saying. The "criminal records" there is in reference to the children, not those providing the money. I was concerned about the people providing the money.
Oh ya, the user terminals out there are going to have to be replaced wholesale. My only point was that Sprint is going to be able to convert to LTE a lot quicker than people expect. Building up a user base is another issue entirely.
One of the largest problems with the sun-jvm GC implementations is they have global pause times to rewrite pointers. This is (in part) because there is no read barrier, and thus all threads must be paused to be 'fixed' after object moves.

Additionally with CMS, there is global heap fragmentation and recompaction which can take literally minutes on a large (8gb+) heap or slow machine.

Setting aside exact figures, can you comment on the above challenges and issues?

You would also need to change the entire ecosystem: if you use standard mattresses, then you can leverage the existing supply of sheets etc. Which is not to say it's a bad idea, but I imagine there's much more involved.
You can exchange it for something that you can eat and you can exchange it for somebody to build a house for you, just like dollars. Unlike dollars, you can't produce it out of thin air.

they mask the model numbers of their mattresses so you can't find them online for cheaper

This practice predates looking online for cheaper. They all obfuscate model numbers so you can't do comparison shopping or "price matching" in the real world. It's shameful.
This was a great examination. Thanks for this.

No; Twitter originally argued that privacy laws were being violated by this request. They should have stuck to this position and contested any contempt fines. Someone has to be willing to get involved and challenge this if privacy law is indeed being violated by the district attorney or other parties in these cases.

This is actually a problem in the area this article is from. In maryland the yellow light is much shorter then in virginia, therefore maryland drivers tend to stop at yellow lights in virginia which causes lots of close stopping of drivers behind . If safety was really a concern then there would be a more narrower range of allowed yellow light duration between counties and states. As far as the speed cameras are concerned they only reduce speed for a very short distance once everyone knows where they are, its a pure profit motive.
IPhone 4S VS iPhone 5 – Differences between specs
It would require an incredible amount of ad spend to change cultural norms which have been created by advertisers over generations. The chances of it happening are miniscule, and the startups who are attempting to do it would go bankrupt several times over before it was even close to being achieved.

It actually reminds me of a Warren Buffet Quote “If you gave me $100 Billion and said, ‘Take away the soft-drink leadership of Coca-Cola in the world’, I’d give it back to you and say it can’t be done”
Sure they are. What would constitute data if not actual use cases? I'm not defending Windows or Linux as great alternatives, but at least "wipe and restore" is not the default answer to minor problems.
The article hints at this, but Ikea solves all these problems. They have a small set of easily discernable mattress lines that are priced extremely well.
The price point is carefully thought out. Its high enough to make a profit but low enough that most people won't go out of their way to fight the ticket in court etc.
I used zennioptical.com in 2008 and was very happy. Lacking any fashion sense, I ordered some computer glasses that I hoped would completely disappear on my face - #804811 titanium shape memory rimless, single vision, high index of refraction, with various coatings delivered for under $40. After two years, the nose bridge broke and I took it around locally to see about a repair. The local repair guru quoted me $45 to solder them back together and he started filling out the order, when I stopped him and said I paid less than that for the whole pair of glasses. Turns out Zenni also sells the frames separately, $14.95 for that item, and anyone can install the old lenses into the new frames.

Most people want a logo designed for thirty to fifty dollars. Some people want ebooks created from word documents under a for hundred dollars.

I would expect those prices too if I went through TaskRabbit. I wouldn't expect the designer to be a top professional. I'd be looking for a deal.

My advice (and I've been working freelance for about 7 years) is to brand yourself as a top shelf designer and never offer your services on outsourcing websites. Go hyper niche instead in a category where you have some contacts and can get work fast.

If your designs are amazing, word gets around. Pretty much all new business I get is from word of mouth.
>But in general, if you make extraordinary claims, you need extraordinary proofs. To argue against mathematics (in this case, game theory and evolutionary biology) is an extraordinary claim.

To argue that humans (and criminals in particular) behave rationally is a far more extraordinary claim. I believe in using evidence over theory (much like in medicine - see the use of blood-thinning drugs after heart attacks) - and the (admittedly imperfect) evidence we have is that prison sentences are ineffective in preventing future crime.

Having worked for one of the major mattress firms, there are truths in the article, but also some serious mistakes.

The pricing structure, where they hide the models by using different names across retailers, is 100% true. They absolutely do that to prevent price shopping.

The markup math is off. Mattresses are a high margin business, but most of those mattresses you see in specialty retailers are not built until someone buys one. You see, those mattresses are custom to the customer - from the tick (stitching pattern, which creates a firmer or softer surface) to the foam density, to EVERYTHING. It's like ordering a car where the car is measured to a specific person's height, weight and engine preference. You can imagine what a returned mattress is worth. Pretty much nothing. The margins have to cover all of that. Are the margins good? Yes. Would a small company be able to cut their margins to make one-off custom mattresses and compete? ...maybe.

Finally, there are retail outlets - Costco, Ikea, that buy from those mattress companies in bulk and sell generic mattresses much cheaper.

So, yeah, there's some market there but not as rich as some might think.
Was anyone else disappointed to see no favicon for this site?
yeah, a /64 is more than 2^32 times more than all of current internet... i don't think the GP really meant 'sufficient', or i'm missing something.
Also, tying back into what you said about efficiency: AC power can be much more efficient due to this easy transformation. The power dissipated across a resistor (which is a reasonably good model for power lines) is directly proportional to the square of the current passing through it. Thus, by stepping power up to high voltages, you can drastically cut the current and hence resistive losses in the line.
It's nice that certain organizations such as Stanford have actually relinquished their ipv4 /8 block to help with address exhaustion.

I can update the chart if someone finds a definitive price.
> A new iPhone is released only once a year, so it better be very good with a lot of new technologies, features, new designs etc. for sales to last all through the next year.

Regarding this, my question is why? Year to year non-computer products have fairly mundane upgrades. Cars get a bit more efficient, a bit safer, a bit roomier. Appliances get a bit more efficient, a new chrome, etc.

Apple's computers aren't major upgrades every year. Every once in a while, sure with the Intel switch, the retina display, the Macbook Air. In general though, once it's released it's a mundane upgrade: better CPU; better GPU; more RAM.

What is making phones so special that they need this high rate of change? 2G -> 3G -> 3GS were all major upgrades. That's a reflection of their time. 3G tech was just getting serious when the 2G came out, so the 3G upgrade was significant. The 3GS offered much better graphics/CPU performance as a reflection of new developments in the mobile CPU/GPU space. Much like how PCs have reached a stable point with their CPUs the same is happening to the mobile space. Why does it need to be so revolutionary every single year?

> iPhone 4S sales started lagging in the 3Q itself this year, compared to the 4th quarter for the iPhone 4. This is because people start waiting for the next version or switch to the competition because they have better specced devices with more features.

I think one of the major differences between the 4S release and the 5 release was the expectation. The 4S was not expected to be a major leap from the 4 so people kept buying it, also the 4S release date was months later than originally anticipated.
