Thanks for the info for an example of pricing that takes into account costs when scaling (meaning more costs with more usage). I am also curious on what other saas owners are doing with these situations. There also is another set of saas apps which when the usage goes up, costs don't scale up proportionally so pricing would be a little more arbitrary relative to the market I would imagine.

That's not what people mean when they talk about "learning styles" and I'm pretty sure you know that. Heck, it's even right there in the first sentence of the article:

> Learning styles — the notion that each student has a particular mode by which he or she learns best, whether it’s visual, auditory or some other sense — is enormously popular.

It's the idea that every person as a particular sense or modality through which they "learn best" and it doesn't change with time. It comes attached with the idea that it makes sense to bucket students into "auditory learners," "visual learners," and so on. That in turn informs curricular and pedagogical decisions, e.g., "Make sure this lesson has a visual component."

I've been teaching programmers for two years, currently through CodeUnion (http://codeunion.io) and formerly through Dev Bootcamp (http://devbootcamp.com), and my personal experience is consistent with two things:

1. The idea of "learning styles" is rubbish
2. EVERYONE believes it, especially students

If I had a nickel for every time I've heard my students say something like "This explanation doesn't really work for me — I'm more of a visual learner" I'd be the Scrooge McDuck of nickels.

what car are you driving and how much mileage was on it when you bought it?

I honestly think to get from point A to B, a used car will do the job just fine, sounds pretty good from what you've described.
Well, I can get 6lbs of coffee at Costco for $42.99 (price from their website). According to Folgers for 6floz of water (a small cup of coffee) you need 1tbsp of ground coffee. Another site suggests one tbsp of ground coffee would be 4.5-7g. Looks like the coffee pods can brew up to about 12oz.

So per 12oz, coffee beans are going to cost $0.14-$0.22/cup. Since I didn't shop around for prices on the beans, I won't for the k-cups either: the cost per k-cup at Costco seems to be pretty close to ~$0.65/k-cup across the board.

That's at least a 195% increase in cost.

If you're just having the occasional cup of coffee, it's not worth worrying about. At 3 cups a day all year that would be around $500.

If you clear $25/hr after tax, that means you're spending 20 hours at work to pay for the difference. Even if we assume you brew each cup of traditional coffee individually at 2 minutes each to a 1 minute k-cup, you're saving 18.25 hours per year.

Whatever way you cut it, it's seems like it's a net loss to me. And the coffee tastes terrible.

Yes, but not as an authority. Your references all had college degrees or prizes listed, as though that added weight to their opinions. My Buffet example was limited to saying how he dealt with popular equities mythology, i.e. by rejecting it out of hand.

> Off the 10% of the people, who beat market handily?

Do you understand anything about probability? For a sufficiently large population of investors, even in a market that doesn't gradually increase in value over time, some of those investors will become fabulously wealthy by chance alone. As shown here:

http://arachnoid.com/equities_myths/index.html#Market_Model

Quote: "In this random market, with no investment strategy, the most successful of the 100 managed-portfolio investors increases his original investment by 2,330%, solely because of chance."

Now imagine the results for an investor pool of a million investors instead of 100.

> Will you still conclude blackswan? Or would you start thinking Conditional probability

1. If an investor makes a killing, why would he care if it's a black swan or the outcome of conditional probability -- and has it occurred to you that both terms mean the same thing?

2. Learn about science and probability. Stop making assertions about a system you clearly don't understand.

I think you're confused by my original statement. By "came up with the exact same language by chance", I mean "came up with the exact same language without reference to idea generator," i.e. your copy of the text was independently created.

Under U.S. law, there must be actual copying in order to infringe upon copyright.[1] Note that is different from patent law, which does not protect independent "invention".

That doesn't mean you can get around the Happy Birthday copyright[2] by simply randomly generating six note sequences until you get the one you want. That's still considered copying for all intents and purposes.

On the other hand, let's say you somehow never heard the Happy Birthday song and somehow just came up with them on their own. That's fine -- no copying, no infringement. This is what I was referring to.

[1] http://en.wikipedia.org/wiki/Substantial_similarity

[2] There's actually a good argument that the song is no longer copyrighted. http://arstechnica.com/tech-policy/2013/06/filmmaker-picks-a...
Oh yes, I'm aware of that stuff. If somebody reasonably competent wanted to resolve my real name from this dummy account, I have no doubt that they'd be able to do it. My concern, however, is not that malign people reading Hacker News will try to discover who poke53281 really is (surely I'm not that interesting); rather, it's that I don't want clients Googling for my real name to easily turn up accounts of my drug-taking exploits. It is probably still possible to start with my real name and find this account, but that would be a vastly harder task -- a much smaller needle in a much larger haystack -- and again I can't actually imagine anybody being sufficiently motivated to do so.
This is a good point, but there are also several Uber benefits over car ownership. For example, being able to travel when tired/inebriated. Also, not being late if you have an engine issue or get a flat tire. This article tries to enumerate the financial differences, the subjective ones are also very important.
Wow, car costs per mile are extremely cheap in the United State, if $.30-.40/mile is typical. The government estimate in Finland is about $.90/mile, and almost nobody has it that cheap. If I recall correctly, I calculated my own costs at around $1/mile, and I drive a 14-year-old car which requires very little maintenance.
The benefit of the charge card (Disclaimer: I have an Amex charge card) is that you can have an extremely large line of credit for those 21-30 days. It's less for balancing your finances and more for spend management (they have great tools to see where all of the money is going, very nice management for multiple family/corp cards, etc).

I'd still trade the charge card for their Costco version.
That's largely it, but it's not just that it's simple; like Alpha, the RISC-V ISA has been carefully crafted to avoid choices that burdens implementations (be those simple or advanced).

A few examples of this (none of which are unique to RISC-V except in aggregation): no delayed-branch semantics, source and destination registers are always in fixed location (see then store vs. load encoding) and are always explicit, sign bits are immediate fields is always in the same location, etc.

I agree that the current implementation of the idea is rubbish. However, it is important to note people can be vary bad at a wide range of things. Just as an example, some people really suck at spacial relationships.

In that context, covering every base is less important than having multiple approaches.
Having done these calculations a while back, I was seriously thrown off by this claim:

> However, Americans who drive less than 9,481 miles in a year should seriously consider ditching their car, because UberX will be cheaper.

Well, maybe. I drive 5k miles a year and determined that it would be more expensive to shift to either UberX or Zipcar. Let's see what is up with the math:

> Costs of ownership

The largest error is here, where the author uses a constant number regardless of miles driven -- and then compares it to variable w/ miles UberX costs!. But maintenance, insurance, depreciation, and fuel costs are all costs that increase with miles driven.

Secondly, all these costs are taken from AAA numbers that are looking at 5 year depreciation of a new car. If you drive an older vehicle, your costs are nowhere near this high. (if they are to be believed, my cars' annual depreciation would be 80% of the value of my car!)

> Parking costs at $1300/year

First off, the claim on ABC is "average American family", not "average American" (http://abcnews.go.com/WNT/video/average-american-spends-1300...), so this is likely off by a factor of nearly 2.
Secondly, this is massively skewed by location. In dense locations (say SF), this can shoot into $2000+ a year, but in lower density places (say San Jose area), this may be well under $200.
Finally, workplace parking can be paid by pre-tax dollars which lowers this cost by another 30% or so.

> Opportunity costs

Where is the assumption that car driving is at 0% productivity and UberX riding is at 50% productivity coming from? (I definitely don't believe this empirically) Also note this is ignoring any opportunity cost of having to wait for an UberX to arrive. The real opportunity cost difference may be insignificant.

My own conclusion:
A single article won't allow anyone to make a determiniation. UberX may win in some cases over owning a car, but it is highly dependent on individual behavior.

No, it makes much more sense to start with the command that is to process the file. Most commands take a command line argument to specify which file to process. This mirrors the redirection syntax perfectly:

You say:

grep haystack needle.txt

or:

grep haystack < needle.txt

whereas this is more convoluted:

cat needle.txt | grep haystack

As a bonus the syntax looks the same for output redirection:

sort < infile.txt > outfile.txt

whereas this is not as readable:

cat infile.txt | sort > outfile.txt

What "makes sense" to you doesn't always to other people. In this case it's trivial, but it's a nightmare to debug larger scripts when there are lots of unnecessary redirections and if statements.

Shell scripts may be one-offs, but they tend to linger. It's not unwise to spend a few extra moments to make them readable and follow best practice. It is code after all.

(Also; a bit silly with the personal attacks.)
> In 1776, Adam Smith famously wrote: “It is not from the benevolence of the butcher, the brewer, or the baker, that we can expect our dinner, but from their regard to their own interest.”

> Economists have run with this insight for hundreds of years, and some experts think they’ve run a bit too far. Robert Frank, an economist at Cornell, believes that his profession is squashing cooperation and generosity.

It's embarrassing that the author directly quoted Smith while completely failing to understand the quote. The point is that self-interest causes cooperation.
In the example from the article we are talking about, it would be easy to mock out the one function call for modules A, and B. There's no DOM manipulation in the article.

Keeping DOM modifying code separate is good practice in either case. Then you don't need to involve the DOM in much of your code. Doing end to end testing is also completely ok to do.

It's worth repeating, so I'll say it again... It's better to keep DOM manipulation code separate. Then you don't need to mock, or simulate anything. Except where needed. You do need to test DOM manipulating code somehow.

AngularJS also uses the DOM in their tests: https://github.com/angular/angular.js/blob/master/test/ngAni... Here's a jquery-ui test for comparison: https://github.com/jquery/jquery-ui/blob/master/tests/unit/s...
I had a friend who worked on a very deep sea drone. He told me that it was better to flood as much of the drone as possible to minimize the strength of the pressure vessels they had to build. The one exception to this was the buoyant components, which had to be hollow to work. These were made of hollow ceramic spheres of exacting sphericity. A sphere provides maximum enclosed volume and strength for a minimum amount of structure, so was a good choice for the pressure vessel shape. They had to be so perfectly spherical to force the pressure to be balanced across the sphere and distribute the compression evenly.

Not sure if this was the exact drone he worked on, but the spheres look like what he described.

edit

I recommend taking a look at consumer reports, look at make models for cars you are interested in, look at the used car reliability history and pick the cheapest possible car with perfect or near perfect reliability over the last 5 years. Then buy a brand new version of that car unless it's the first year of an all new model year. If that's the case, you can usually buy the outgoing model at a discount and benefit from a few years of manufacturing know how.

I came from a family thought bought exclusively used cars (and still does) and in the time I've owned my 1 car I bought new, my parents have been through maybe 7 cars? A friend of mine who also buys used exclusively, but doesn't consult Consumer Reports has been through 11 cars.

I also went through a string of used cars until finally deciding to just buy new. You might get lucky with a used car, but you never know what's happened to those cars and most people end up getting rid of cars because the repair costs are getting too high.
I know I'm going to suffer hard for this comment. However I'd suggest reading the ZFS optimisation guide.

I know the allure of raid 7 is strong, however if a disk were to fail on a LUM thats 24 disks wide, the chances of a rebuild is pretty low. (I know you've since changed that) the rebuild time is around 60-90 hours with no load.

(we use 14 disk raid6 LUNs for the balance of performance vs safety, however we've come pretty close to loosing it all.)

You'll get better performance if you have many smaller vdevs. You'll also compartmentalize the risk of multiple disk failure.

a raid 0+6 of four LUNs of 5 disks will have much greater performance, and will rebuild much faster, without risking too much. However you will loose more space

No, it's still not burning renewable fuel. It intrinsically turns a fissile or fertile product into a lower energy product until it's no longer fissile. I am aware of breeder designs - I mention CANDU reactor designs later in the thread which can be used as a breeder with unenriched U, Pu239, or Thorium inputs. This stretches out the fuel supplies substantially, but it's still nonrenewable. Solar is, as long as our large scale fusion reactor is still running.
A Financial Model Comparing Car Ownership with UberX
The cost of car ownership in this article is inflated by almost 200%. It accounts payments / depreciation + interest + registration as $5,561 yearly for a mid sized sedan.

I've leased two mid-size sedans for $200/mo and $300/mo including interest, all taxes, dmv / title / registration fees. So, I am paying $2,400 / year for one car, and $3,600 /year for another, compared to $5,561 represented in the article.

> They do a particularly weird instrument called a "charge card."

It should be noted that they also offer regular credit cards, in addition to the charge card, and these do not require payment in full at the end of the bill cycle.
Actually it's not difficult. Calculate your hourly wage (salary + benefits)/hours_worked, and value all of your time as such. It will help you a lot to avoid wasting time doing stuff you don't like that you can pay people to do for you at a lower cost to you.

Nope, you're right on the money. My first thought was "this guy needs more VDEVs". Given the hardware and use case, 4x 6 disk RAIDZ2 VDEVs would make a ton more sense, and could also be cross-cabled to allow a controller failure.

This comment starts out as a shallow dismissal, rejecting the article with generic hand-waves, and then nose-dives off topic.

The article may be wrong but is not unsubstantive, and it appears to describe work done by many researchers. It deserves better. A better discussion would engage seriously with specifics. "Seriously" implies making less wild claims and trying to substantiate what one says.

There's a grain of a specific response here: the claim that the links don't point to data that can be inspected. But that doesn't mean the work is worthless, just that academic paywalls are a problem.

We did change the linkbaity title (probably not the work of the author) to a sentence from the article, and added a question mark, in the hope of dampening this sort of reaction.

> The reason this distinction is important is because disputing the charge/verdict requires getting involved in the case and seeing the prosecution's evidence.

I don't agree at all but I also think we've seen enough of the evidence that there's not really much factually to dispute. (We know a lot more than the jury did, which is a very common and very depressing situation but also a separate topic)

Anyhow, felony charges are usually reserved for people who do a lot of damage, on purpose, and who have prior convictions. I agree that there's a distinction to be made between the seriousness of charges and the severity of those charges associated punishment - they're determined by different parts of government, if nothing else - but I don't think as much hangs on it as you seem to, vis a vis the way different places treat crimes more or less severely. Heavy handedness in one area correlates with heavy-handedness in the other, after all.
The simplest form I can think of is a beacon broadcasting its location along with a stay back distance (with the routing system in the vehicle left to deal with the details of compliance).

That doesn't address security or authentication, but it should be fairly easy to track down a broadcasting radio, and it should also be easy to log and aggregate the active beacons that have been spotted by vehicles. With that context, traditional enforcement tools should probably work well enough.
