The problem is that a diamond is inherently a basically worthless rock, so its retail value is already a figment of the public's imagination. Blue Nile is the closest that exists today, but they are not that disruptive since the retail channels already have lots of competition -- it's the supply (De Beers) that's monopolized.
How does price matching work? One of the major problems with mattress stores is that everybody sells different mattresses -- they're 99% identical, but tiny changes are made to justify a different name and prevent comparison shopping and price matching.
Has something changed since 1999 when I, with zero money or savings in my family, was able to go to college on government loans/grants based on the fact that I got in due to good grades/etc?

Yes. College tuition costs have been rising way faster than the rate of inflation.

Verizon doesn't do rollover minutes month to month though which is very annoying.
Yes indeed I'm very aware of this. The overall architecture and abstractions can support efficient multi-core operation, but the implementation is behind. Development is mostly paid for by single-threaded clients at the moment! But I have plans. Well spotted, by the way.

Most of the problems are around the bottleneck of stopping threads on other cores in order to get privileged access to memory while preserving their consistent view of the heap. What the MPS needs is its own protection map. Most OSs don't help much with that, although Mac OS X, for a while, allowed you to map the same physical RAM at two addresses with different protections. Sadly, no longer.
Does anyone have info on the Sprint tethering pricing listed here? I don't see it on their site or a Google search, and the existence of such would be very compelling for me (obnoxious overage price notwithstanding).
My point is: is it stressful just because you feel it is stressful, or did you actually put a plan/budget together and feel stressed out after looking at the results of that?

Think about this, would you rather be stressed about this now, when you have a lifetime of earnings & potential ahead of you, or later, when you realize you can't retire when you want to because your retirement fund is low?

How do you find industries dominated by PE?
You realize these pet topics are only 5 university courses. It would be a intense 4 month semester, but it's workable.

1. full understanding of computer architecture, realizing how the CPU executes code
2. analyze efficiency (Big O) (a few hours), knowledge of advanced algorithms
3. understanding compilers
4. knowledge of the OS workings (often self taught out of necessity)
5. AI fundamentals (Admittedly a specialized topic)
I Cut This From The Email Before I Sent It...
Finally, I’d like to add that the initial requirement was to post these documents to [Company Intranet] in such a way that target audiences (EX: Canada and USA) were able to see only the documents relevant to their location. This requirement has been satisfied. In the interest of efficiency, requirements should not change very much throughout a project. It is imperative that requirements are clearly defined at the start of a project and it is the responsibility of the analyst to define these requirements. Going forward, I would very much appreciate it if you could ensure that the requirements are clearly defined before asking me to create something you don't even want.
Reducing the number of patented algorithms does not solve the fundamental problem, which is that algorithms are patentable. Letting people reserve pieces of mathematics for their private use is and will always be a disaster.

I completely agree! I recently went shopping for a mattress at Sleep Train and they admitted that they mask the model numbers of their mattresses so you can't find them online for cheaper. Someone please build this.
I got my last mattress from Silver State Industries (nevada prison manufacturing) for under $500 (Cal King). It is more comfortable than the Serta that I had originally spent around $1,500 on.
My thoughts exactly. Once again, poorly-considered reactive security measures waste money and accomplish absolutely nothing useful.

And we all know that as soon as this starts happening, they'll install security cameras to watch the security cameras.

Or, you know, vandals will just wear a $5 ski mask. No sense reinventing the wheel on that one.
Your story is very similar to mine. I too was a poor farmers child growing up. But thanks to Pell Grants, Federal Student Loans, and my parents vision for me, I was able to go to college. My parents greatest vision for me was that I would be able to do better than them. That was the goal that was drilled into me, that I could do better. That I had a blank slate and could make myself whatever I wanted. And they made sure I was keeping up with my grades and not going out and getting in trouble. I believe its very true that a bad or ignorant home life is probably one of the greatest disadvantages a child can have when it comes to education. I don't have the studies or facts handy right now, but from what I've read and seen myself, English as a second language and disengaged parents are far more responsible for poor test scores and student failures than the teachers are. Of course there are bad teachers, just like any other profession, but I would guess that the number of incompetent and bad teachers is far lower than test scores would suggest.
This makes no sense, Lets say i was to get an iphone 5 keep it for 3-4 months so that is 199$ + 285$ termination fee. that makes around 485 $ , and then sell my iphone 5 for like 515 $. I would make a profit, or is there a 6 months or so no changing carrier clause. ( As i am not an american i don't know how these things work)
"The transition has sort of already happened," he says, over IPv4.

Seriously, unless you want to be posting to HN via IPv4 in 2050, there is clearly something major left undone. Don't call it a transition if you think that concept is undone, but it's not yet functionally possible to be on the Internet with no IPv4 stack or (possibly NATted) address, and I don't see that becoming the case anytime soon.

See http://cr.yp.to/djbdns/ipv6mess.html for a description of the problem that I mostly agree with. The depressing thing is that those complaints are no less valid a decade later.

Maybe just my opinion, but I don't think HN submissions should be used to test which headlines get more clicks. (Wouldn't that pretty much fall into the "Link Bait" bucket?) The HN Guidelines[1] has some pretty clear, simple text on submission titles. It mostly boils down to "use the original title... unless a few of the mentioned cases exist".

Another classic example of "what is good for the individual is not necessarily good for the group" (the exact name of the economic theory escapes me).

Sure, for you, the cost/benefit scenario might not work out. You seem to be doing quite fine. However what about the people that created the languages you use? Those who built the processors you work on?

A lot of people will never need the things they teach in a standard CS curriculum. I doubt most programmers even know how to spell "automata". But then again, most programmers aren't doing anything new or ground breaking. Most programmers are simply rehashing solutions to problems already solved somewhere, or simply making small iterative steps. I have found that my own work seemed very "small minded" before I began my formal studies.

Even beyond that, I am now equipped to do most anything I choose involving this discipline. I've always wanted to create my own language, and now the only barrier is simply the time and effort I need to put in. I have all the requisite knowledge and background, and my solid foundation will allow me to easily (comparatively) pick up any new concept I might encounter.

The average programmer might never desire to create their own language, but for this field to continue to grow we need people to push the limit and innovate beyond our current limitations. To do this you need to have a deep comprehension of what you are working with.

However even beyond all of that, I wasn't content with not knowing the intricacies of computation. Maybe I'm just a naturally curious person (and possibly biased), but in my opinion the world of Computer Science is one of the most fascinating fields to have ever studied.

One last point... why not? Knowledge is power.

Edit: After reading some of the replies posted while I was typing, I'll agree there are outliers. You will always have those people who are able to become masters of their field with no formal training, but then again, those are a select few.
How many planes have been bombed full stop? As an attacker, why would you ever try to bomb a plane? Unlike a hostage-taking/hijacking where there are obvious advantages to being in a plane, if you just want to plant a bomb and kill some people you can do that much more easily in a building, or on a train, or...
> One reason it's common for GPU makers to be secretive is that there is a very big risk that GPUs and their drivers violate patents, and the makers of these products want to make it as difficult as possible to ascertain whether patents are being violated. They won't even broach the topic because that would draw them in to willful infringement.

This is another example of how patents are directly counterproductive to their originally intended goal of encouraging open innovation. Patents are not just creating a minefield, but are encouraging everyone to be more secretive at the same time.

I was excited to use MPS in the runtime of an open-source compiler, but if users of the compiler had to pay in order to use it for closed-source apps then that would be a big turn-off.
> you're just given some basic data structures that handle pretty much everything under the sun, and you go from there

This only works because the size of your n is small, possibly a few hundred, so it doesn't matter. When you start dealing with millions or billions of records this stuff matters. Quite a lot.

So really, it's not the language, it's the size of your data - or the size of n that matters.
That's a smart professor. My favorite ones also worked outside of academia; they didn't have rose-colored glasses.

Thanks for your feedback. This site was just (very) quickly put together in order to test the waters and see if startups were interested in outsourcing brand engagement at all.

The idea is that founders want to build a great product their users love, but they also want to build a relationship with their users (by building and strengthening their "brand"). However, as important as brand engagement is, it's really just a distraction from the awesome product they want to build and improve. We want to take that hassle away. We'll design, print, and ship any sort of physical item that features your company's brand. You just tell us what and who to ship it to.

The problem is that many people like to lie on a mattress before they buy it. Sure, that's a little silly since lying on it for a minute or so is unlikely to capture the experience of tossing and turning on it for a night, but it's clear that it's a competitive advantage to let the consumer compare a few models in a physically direct way.

Warby Parker can get away with the similar consumer requirement for glasses because glasses are small, light and easy to ship. They can send you half a dozen samples and let you pick the one you want. Not so easy with mattresses!

The car market has this problem as well (in addition to others, like the protectionist rackets that the dealerships have set up).
Anyone who googles "wheel well stowaway" finds out the risk. In one google.

Twitter turns over OWS tweets after threat from judge
How many judges know enough about the technology present (or not present) in speed cameras to legitimately scrutinize it?

In any case, I was under the impression that it was just a radar gun which tripped a camera once a speed some threshold over the limit was detected. The expensive part would be something to find and OCR license plates, and presumably feed that into some other automated system - theoretically a one-off software cost.
While you're disrupting the mattress industry, please consider re-thinking the King form factor. Changing the aspect ratio by just a few inches would make it perfectly square, which allows for you to rotate 90 degrees as well as flip, so the whole thing would wear out more evenly.

As an extra bonus, this would make putting sheets on easier as there's no wrong way (short of inside-out, I guess).

If the program is non-trivial (e.g. contains some classes, many functions), then usually the program structure alone will give it away (1), unless you invest a lot of time into changing things.

From my experience (as a student), the people that copy programs don't even work that hard to obfuscate their plagiarism. Usually they just rename a couple of variables and reformat things a bit. A former professor of mine wrote a program to "fuzzily" compare two source codes and show how close they are, which quite nicely showed of clusters of programs where a bunch of students had copied-and-slightly-modified from one student.

Erlang's error handling is very well thought out. In fact, error handling is the main reason Erlang is shaped the way it is.

It is a combination of Go's technique but with panics for exceptional errors.

Like Go, functions should return error values for known errors. For instance, `file:open/2` returns `{error, enoent | eacces | eisdir | enotdir | enospc}` for known error conditions that can be handled. Unknown, exceptional conditions, like a NAS going down, can't be compensated for because the set of unknown errors is unbounded. There could literally be an infinite number of things that can go wrong that you don't know how to handle. For try/catch style error handling, the only safe way to handle the unknown errors is to do a Pokemon catch clause globally or around every single potentially error causing function call.

Because of the fact that you can't stop errors from happening is why Erlang has processes. When an unknown error occurs, the individual process dies and anyone monitoring that process is notified. OTP has supervisors whose sole job is to watch over processes and restart them if they crash.

Any state that needs to be preserved between restarts is stored somewhere safe (Erlangers calls this the "error kernel") so that when the process comes back it'll resume where it left off.

Once you structure your code to "Let it Crash", your code gets much simpler and safer. #1, the error return values forces you to compensate for known errors that can happen with a function, #2 you have to think about data durability in order to "Let it Crash". #3 Supervisors take care of the rest.

Data durability is made much easier with the fact that individual processes are single threaded and data is immutable, this makes them transactional by nature.

Logically, it makes more sense to pay off the loans on schedule, and put additional payments into a vehicle that will provide returns that will outpace the interest rates on the loans.

However, personally, I would rather have no debt.
Although the thread is old I want to add something:

"There are certainly no side effects. One sheet defines a complete set of data that does not change at run time"

-- this is not true. Just changing an input somewhere (and triggering any related recalc) counts as a side effect. Your view requires "freezing" the spreadsheet at a given point in time. This is misleading, because spreadsheets are so interactive. Even your friend, who doesn't change the inputs after entering them, still has to enter them in the first place. There are a whole lot of side effects happening while she does that.

The Achilles' heel of pure functional programming, I/O, is not a problem for spreadsheets, which are a kind of REPL. Their way of doing I/O is highly specialized (you can edit a cell but reading from a file is not so easy). But that's fine: the fact that spreadsheets aren't general-purpose computing environments is part of their strength.

It's a mistake to look at spreadsheets qua programming language without taking the UI into account, and once you do take it into account, the FP analogy breaks down. In my view, a more reliable way to understand spreadsheets is as belonging to the class of interactive computing environments populated by Lisp, Smalltalk, APL, and Forth.
> a mattress purchase only happens once a decade

This is a cultural artifact. We've reached a point in manufacturing technology where this should no longer be true.

> disrupting the mattress industry as a manufacturer AND retailer...Like IKEA,...

The most comfortable mattress I've ever slept on: A Sultan Fonnes mattress, with an egg crate foam topper from http://www.foambymail.com/ on a platform bed, no box springs. You can leave off the topper and save about $60, if you like, and you wind up with the equivalent of a great firm futon that never bunches up. The combination for Queen is well under $400, including taxes and shipping.

My plan for instant "satisficed" sleep furniture: Buy a cheap platform bed, a Sultan Fonnes mattress, and 3 eggcrate foam toppers. Keep the combination with the topper you like best and sell the other two. No going to the store needed at all. It could all be done through the mail and by delivery in most of the US.

I am not associated in any way with IKEA or foambymail.com except as a customer.

If you buy the phone outright, T-mobile no-contract plans work out to cost less than subsidized contracts, as it should be. The other carriers want 2-year lock-in so bad that they refuse to offer different terms when you own the phone.
This is true and something I should have mentioned.

Humans can function to varying degrees at lower partial pressures of O2 than you experience at sea level (obviously, since people live at altitudes of up to 12K ft).

If you have not adapted to high altitude, you will experience cognitive decline at altitudes much higher than 10K ft, although they can be imperceptible. You can also go up to 30K ft, lose consciousness, but experience no long term harm as long as it's not for extended periods of time.

There have been glider pilots who have been caught in massive up drafts, climbed to 30K ft or higher, lost consciousness, then regained consciousness when they descended and safely landed their planes.

Why website management services are becoming more important
Time is an important advantage but not everybody has enough time to handle their own website maintenance successfully.

The real disruption will come in the form of widely available manufactured (not mined) diamonds.

I used to think of diamonds as basically worthless rocks, until I went shopping for an engagement ring stone and looked at them under the jeweler's microscope, and thought "I want to be dressed from head to toe in these things". With mass-produced diamonds, that may become a reality.
"By the time a customer buys a mattress, it costs them ~74% more than the production cost of the product."

I'm not arguing that the mattress industry isn't ripe for disruption, but very rarely is value delivered directly related to the cost of production.

COGS is often difficult to accurately estimate (how much do you allocate R&D and other overhead?).

An iPhone 5 may only contain $110 worth of silicon, but the value delivered is a lot more than the raw material cost. Jony Ive's salary represents a tiny fraction of each iPhone, but his design and influence represents a significant chunk of the profit.
