Believe it or not PA has one of the highest rates for in-state tuition. The per credit hour rate for my post 9/11 G.I. bill is based on the highest in-state tuition for a state school. Last time I checked the per credit hour rate for PA was about $900 while in California it was around $300. If I didn't already know better I probably would have guessed that it was the other way around.
As a rough guide, you might factor in another 8-10 hours, because, according to Fred Brooks, a proper programming "product" takes about x3 as long as a "program".

Taking a wider view, there's an appeal to "cloud components", where all components are rented - including ones as simple/trivial as this. For this to work, it has to be cheap enough to be a no-brainer (esp for projects made of such components). Say, 1/100 - pennies - e.g. 9 cents /m/e. In the long-term, you'll see free open source alternatives, and maybe even free hosting (cloud providers supply it free, to support their hosting of your actual app)... and maintained.

I would tend to disagree. The end result is the same: Unless a title was popular enough to have been kept track of across half a dozen storage media changes, restoring it requires fighting against copy protection and is either very difficult or impossible. The ubiquity of such "solutions" doesn't come into it.

Anyway, this appears to have been a copy of the game for the PC. So it's really just trying to run DOS software under Windows, which isn't a terribly unusual thing to be doing.

So the server has multiple threads. If a handler blocks in one thread, another thread can pick up incoming requests. So far, so good. In return for needing to carefully synchronise access to shared state, we get to efficiently share that state (even if its just a hot cache of secure session cookies - things you don’t want to be validating every incoming request etc) between many threads and multiplex incoming requests between them.

Sharing state is bad, m-kay? Allow Node to do it's thing (So the server has multiple threads. If a handler blocks in one thread, another thread can pick up incoming requests.).

It's aggrieving that this model requires any given handler to be able to service any given request, tbh. Shared state is a folly. A serializing token scheme might work well: if a request fails to find the data local to it's core, it passes a serializing token of the request around the ring of handlers, asking either a, for the required data, or b, take the token and run the data.

Serializing tokens are a concept Matt Dillon spoke of often at the inception of DragonflyBSD; much like locks, except that ownership is not relinquished, someone always hold the token, but instead phase changed, yielded to another. it's a responsive less a stateful ownership.

Sadly that token ownership negotiation requires some kind of interruption in the currently-occupied worker thread: if that thread could be interrupted to do other things, this serializing token negotiation might be an acceptable argument (ending with a) no, i'm busy using that set, b) sorry, i had the data and was free, so i completed it, or c) here's the data, i'm busy and not using it). But it does still require thread-interruption. If the worker thread can yield frequently and resume, finding the answer might be a small enough invisible enough calculation to help plaster over there being interruptions altogether; that's essentially the hope. The result would be the mating of green threading to with location aware latency aware multi-processing.

Why don't you just lock each connection handler to one thread at a time and dispatch events on a thread pool ? That way connection level events are always synchronous, but event handlers are spread over the thread pool, you get optimal load balancing because events fill the pool (no processes) and thread pool can use it's own logic to grow if one channel handler used blocking IO and is blocking the a pool thread.

This is pretty much what netty does with OrderedMemoryAwareThreadPoolExecutor ?

I think it really depends on the kid. We don't have the feeling that crying is a bargaining card or that he cries with no reason. If it were, perhaps we would react differently. We never had to try hard to stop the crying, as other parents tell. So we were probably lucky.

Recently of course sometimes he protests when he doesn't like something. I don't want to suppress that completely, though - I think it is good that he protests and fights for what he wants. If it is a good reason he can not get it, he won't get it, at other times, why deny it just for the sake of denying it (he doesn't get sweets, it is more about playing with certain things).
I have several female friends who have been very political about this on facebook for years. But facebook is just one venue for them.

They make this point everywhere, in parks, at work, at the coffeehouse. The point is to make breastfeeding natural. And when you realize that it's not (and it doesn't matter whether it's a well-dressed VP or an MFA student, it is clearly socially unacceptable, or at least uncomfortable, to breast feed in public) - when you realize that feeding our children should be the most natural thing in the world, and it isn't, you can appreciate the militancy with which they fight to make it a common occurrence for the rest of us: like showing up in your news feed.

Either way it will be interesting to see where Facebook et al legally end up. My suspicion will be that it will be more like a Mall and less like a private club.

> it's completely internationalized

Actually, no, it's not. As an Australian, I can't even count the number of times per week that I come across "... is not available in your country". From Amazon products to streaming video/audio services, YouTube videos, payment services, and lately even some articles on blogs.

While I'd love it to be different, the reality is a lot of the stuff you guys take for granted, we don't get to see/use... so I actually fully understand why the EU wants their own localised Hacker News, and even wish there were a good Australian one so I could see cool stuff happening here that I can actually use. Instead, any local stuff posted gets buried by the (understandably) larger number of upvotes given to US start-ups by the mostly-US audience here.
Babies need more than just food and warm clothes. And they are dependent on you for a long time. I don't see the point in weaning them off things when they are still too young to provide them for themselves. For example, they can't just log on to Hacker News when they feel bored. Crying might be the equivalent to typing "news.ycombinator.com" into your URL bar. Is it really so bad to take care of your babies' needs?

>Potentially; one could be a naturalized citizen, or a child of immigrants, or poor enough not to be a net positive contributor to federal revenue.

You're taking a very limited view of "investment" here. The point is everyone is responsible for the efficient operation of a nation. From the CEO's to the janitors. The country could not function without either of them, so they all contribute in important ways.

>The fact that a given individual belongs to an arbitrarily defined class of people does not give that individual any credit for what that class of people has collectively done.

The boundaries of a nation are not arbitrarily defined. This isn't a grouping of people based on hair color. National boundaries have real importance. Each worker, each person who is doing their part in a society is party responsible for its successes. The groundskeeper at a park should in fact be proud to be American when we launch the space shuttle. There's nothing illogical about it.

>You can take that same argument and use it to justify racial segregation.

Bullshit. The country prospered in part because of slavery. Your focus on dollar amounts is extremely short sighted.

>No, I'm taking an individual-centric view

The problem is an individual-centric view does not capture all the important interactions in the system. The nation is a very important unit. It may not be ideal, but the fact is we do operate along national lines. Trying to argue that we should ignore it just doesn't work.

>you can get around to explaining how governments are magically better at corporations at hiring engineers.

Like I said, corporations are only capable of operating with self-interest in mind. Laissez-faire capitalism doesn't work, every government regulation in existence is an acknowledgment of this. Making regulations for hiring foreign workers is no different.
The final question/answer is resolved around,

Hellepoll has the concept of a task tree - tasks can be subtasks of others, and this simplifies tidy-up when one aborts. This explicit linking of tasks and callbacks can be used to determine what gets migrated when a task blocks, to ensure that the cascade of events associated with a request do not themselves get split, but fire in the originating thread and in the right order even if at some point the thread triggers the blocking watchdog.

He asks, in closing,

Doctors go through significantly more schooling and receive significantly more professional development — yet they are still perceived with respect as professionals who care about their patients. Why can't we do the same for teachers?

Because peoplegenerally have much less exposure to doctors and when they are they're desperate for either treatment or hope. Both of these contribute.

Also, medical training is much harder than education. There are teachers at every average large high school who could have been doctors but they're a minority.
You are right. The aggregation wasn't a good example of an "action".

About that 'apparently': I guess they would take their time for any joint, but a jaw is special in two ways:

- it hinges at two points. As with doors, those must be t exactly the right distance of each other, or the thing simply will not fit, and be perfectly in line, or rotating the thing will cause huge forces on those hinges. I guess these could easily break of the new jaw or, worse, parts of the upper jaw.

- it must close perfectly flat; you do not want to have only a few teeth touch when it is maximally closed.
Inflation is as logical as 1 = 2
Acording to Quantity Theory of Money, MV = PT.

M is Money Supply.

V is Velocity of Circulation.

P is Price level.

T is Transactions or Output.

Assuming that V and T are determined, or fixed,
P must increase as M increases.

Economists call this "inflation"...

But the logic seems flawed

For one, V cannot be determined.
Think about the impact of Visa, eBay or Amazon.
And of course, the hyper circulation via mortgage derivatives.

Also, T is ill defined.
The output of certain resources, such as precious metal, may be constrained,
But we cannot ignore the renewable ones.
Especially because they are postivily correlated with M.
You know, the concept known as investing

So would someone please show me otherwise?
Or it's going to get really depressing...
Nice question; I'll take a stab at an answer.

Since consumers need producers and producers need consumers, you really can't argue that either one is inherently bad.

However, I would argue that our intent should be biased toward producing, since producing helps us grow. Consuming in this context has connotations of passivity, and while rest is important, too much rest will make us weak. Also, when you are consuming you can be mindless. When you are producing, you stretch your mind. Not only do you have to think about how to meet your goal, you have to think about what you are producing in context of value and other people. It's mind-expanding.

Also, it is natural for us to want to grow, so if we spend most of our time in passive consumption it will negatively affect our mood and sense of well-being in the world.

Why Morning Routines Are Creativity Killers
Had this done to me, in 1981 or so at the University of MD. They decided to teach some kind of "theory of proving programs correct" to a bunch of CS-101 types who were just learning Pascal, too. I guess the hope was that we'd get a healthy dose of mathematical proofiness and write better programs.

One of our first lectures: "Taking this loop, we prove by induction that it computes the sum of the first ten integers. Here are a bunch of logic formulas (lots of scribbles on the overhead). Here's a bunch of notation, it's got CONJUNCTION and DISJUNCTION and COMPOSITION and so forth. By inference [and some hand-waving] this five line program computes a sum, yes?"

Class: "Huh?" Not even panic, just a collective, bug-eyed "<I>What the fuck?</I>?"

The approach failed miserably; what it /did/ successfully teach was cynicism; most of the students were really upset at the obvious nonsense. [I was the only one of about 250 students to complete all the project work . . . and I cheated by writing the project in LISP, and writing a LISP interpreter in Pascal]

I imagine that Facebook are largely just trying to cover their asses. While we have these mothers who are proud to be breastfeeding, there are just as many other prudish mothers who are ready to sue Facebook for allowing their 13-year old to see gasp a breast. And while Facebook may be fine with breastfeeding mothers, they don't want to support their cause financially with their legal department.

I don't think it's a bad thing, but the things that are easy to consume take time and don't provide much benefit.

> The country prospered in part because of slavery.

The country prospered in part because of immigrants.

> The point is everyone is responsible for the efficient operation of a nation.

A citizen who contributes nothing is responsible for "the efficient operation of a nation", but an immigrant who works his ass off isn't? Immigrants designed that moon rocket you're bragging about.

Citizenship is arbitrarily defined, by the way, in the sense that countries can arbitrarily set whatever citizenship laws they want.
