Yeah, it is the original level editor for doom. It ran on NeXT. Many people built separate implementations, based on the reverse engineered wad format. Doombuilder, Slade, etc are examples. There's even one named 'DoomEd', it is, however, not related to the original, never-released one from id.

On the other hand, if you allow outside communication (such as unrestricted access to the internet), you open the door for "I'll pay someone who already knows this stuff to phone in the answers for me" - which isn't generally an applicable skill in the real world.

As an aside, I hated open book exams - if you were talented and knew the material, you could typically blast through a closed-book examination in half the allotted time and get out of there, while the open-book exams were far longer and more tedious.
This is a cool idea. This beats adding futile access control mechanisms to decide who can see data which provides no protection once it has been revealed to at least one party (horse has bolted). Case in point; iOS and Android.

Instead, OpenPDS accepts code from applications which then operates on the sensitive data and returns the outcome so data never leaves a device under your control.

> Also, as a person with ADHD who takes Adderall I don't see what the big fuss about it as a drug/medicine is.

If you, as a responsible adult, consent to taking this medication on a regular basis, then fair enough. The big fuss is that this is being imposed on a whole generation of children, essentially as a form of behavioural control. It's really the revival of the old Victorian "little children should be seen, not heard" mindset, under the guise of medical treatment. Children misbehave at school for a variety of reasons. Instead of dealing with the often institutional causes of this problem, we lay the blame at the children's door and try to medicate them into docility.

CSP ideas have been used in Erlang, Scala (and you say Clojure). But CSP is earlier the pi-calculus. So that's not a good argument for the value of the pi-calculus.

Compared to CCS and CSP, the pi-calculus allows for natural transmission of communication links (think object references in java RMI for instance), and it uses an elegant formalism to do so (scope extrusion). At least, I would say that pi-calculus ideas are useful to give a formal semantics to certains concurrent or distributed languages, which in turns open the door to program verification.

It has also been used for protocol verification.
I'm not sure how big the issue is, but I would add the ability to run your Go app as an restricted user.

Using Nginx or another webserver in front of your app means that you won't have to deal with privilege seperation yourself. Just run the Go binary in a chroot as an restricted user and let Nginx deal with the binding on port 80/443.

"It's not like a graphing calculator app is going to be that difficult to program"

It is surprisingly hard to get something that produces reliable plots. It starts with getting something as simple as sin(1/x) or x/(x^2 + 5x + 1) to plot reasonably well, and gets harder from there soon (edit: if you want to complicate things, pick a function that is only defined on some numbers, such as sqrt(x^2 * sin(x^3 - x). Adding a pair of || around subexpressions also complicates things)

For example, at https://www.desmos.com/calculator (one of the top results from a google search) zooming in on sin(1/x) shows a plot that sometimes doesn't go up to 1.0 for values of x close to zero. Its plot is decent, but deceiving.

And you will have to do those well, as the target audience of students encounters such functions every day.

Schwab 6.875%
TD Ameritrade 7.25%
Fidelity 6.575%
Scottrade 6.50%
Etrade 6.14%

Having said that, I still haven't created an account there, because I agree strongly with what you said:

not that one should ever go on margin
if you don't know what you are doing

For example, look at how the ex-CEO of Chesapeake Energy, Aubrey McClendon, got blown up by margin (from Wiki):

It was announced on October 10, 2008,
that McClendon sold approximately 33.4
million shares, approximately 90% of his
stock in Chesapeake Energy (stock symbol CHK),
for $16.52 per share to meet a margin call
after the drop in the U.S. stock market
that week. The stock had been worth as much
as $74.00 per share in the year prior to the
sale, a loss of nearly $1.92 billion.

Bitcoin code was used for Namecoin, which provides decentralized DNS as well as decentralized CA (credentials free of any certificate authority.)

Bitcoin can be used for proving notice. (Replacing say, newspaper classified ads for the same purpose.) Bitcoin will become the ultimate notary.

Bitcoin makes it possible to wire gold. For example, you walk into a gold shop and hand him some physical gold in return for BTC, which you send to your grandma in Asia. She then walks into a gold shop in Africa and leaves with physical gold.

...Thus, Bitcoin can be used for wiring anything.

Bitcoin, via colored coins, makes it possible to issue real-world assets without having to trust a central entity to control the ledger.

Bitcoin makes it possible to run exchanges anonymously, at a profit.

Similarly, Bitcoin makes it possible to operate bazaars anonymously at a profit. (Silk Road being one infamous example.)

Similarly, Bitcoin makes it possible to operate prediction markets anonymously at a profit. These have the potential to drive scientific progress as well as political change.

...Basically, Bitcoin makes it possible to operate many many things anonymously at a profit.

Bitcoin makes it possible to eliminate capital controls. There's the basic concept of using Bitcoin to move funds across controlled borders, but it goes much deeper.

...For example, let's say that there are capital controls in Argentina, which drive up the Bitcoin price to 130% of its price in the USA. This means that a beef exporter in Argentina, who prices his beef in Bitcoins, will be able to undercut all the other Argentinean beef exporters by 15%, while simultaneously earning 15% more money for his sales. Therefore Bitcoin is destined to eliminate all capital controls.

Yep, I read and upvote from New every so often. The ratio of quality stuff to junk in New is still surprisingly high.
You misunderstand. Political financing in the US is very complex; all I'm saying is that the direct donations by corporate PACs to individual candidates is utterly trivial.

Look at this list: http://www.opensecrets.org/pres12/contrib.php?id=N00009638

"This table lists the top donors to this candidate in the 2012 election cycle. The organizations themselves did not donate , rather the money came from the organizations' PACs, their individual members or employees or owners, and those individuals' immediate families."

So if we look at Microsoft, $800k went from Microsoft and related entities to Obama's campaign. That's a lot of money, and I have no doubt it bought real influence with Obama. But out of that $800k, at most $5k was the money that went directly from Microsoft's PAC to the Obama campaign. And that's well...nothing. It is 0.625% of the total amount given by Microsoft, 0.0007% of the total amount given to candidate Obama.

I have no doubt that BigCorp was very insistent about your contributing to the PAC; but they had no intention of using more than the barest fraction of that money to donate to the campaign of individual politicians. They couldn't, even if they wanted to. They would have been intending to spend it on much more effective (and unregulated) channels.
It probably depends on the subject but if they don't have that basic knowledge they're not going to be effective filling in the test either, even with Google it always takes longer.

Ideally tests should check the deeper understanding of the student and not just his memory skills. In that case Internet access is also not a problem.

Mr Rodgers makes some very good points in his letter. Definitely where it comes to board membership and the ethics of inisiting on 'balanced' board make up.

However I'm not sure about the inherent logic in Paragraph N:

'The May 13, 1996 issue of Fortune magazine analyzed the ethical mutual funds" which invest with a social-issues agenda, and currently control $639 billion in investments. Those funds produced an 18.2% return in the last 12 months, while the S&P 500 returned 27.2%. The investors in those funds thus lost 9% of $639 billion, or $57.5 billion in one year, because they invested on a social-issues basis. Furthermore, their loss was not simply someone else's gain; the money literally vanished from our economy, making every American poorer.'

Is this is implying that if you make an investment choice for personal reasons (maybe invest in a family business) and the company returns 10% rather than 20% that you could have received from a different investment that you have lost 10%. And that you have made the world poorer with that choice. The logic seems a bit hokey to me.

From a productivity based perspective: The older you get the more it would seem to make sense to use the knowledge you have, rather than to invest heavily in acquiring new knowledge. So what you read would become less important.

As for why read sci-fi? Well, there's a lot of bad sci-fi out there. At its best it represents interesting explorations of the effects that changes in science, context, and or very other social structures can have when they interact with human societies - and in that much perhaps tells us something about ourselves and where we might be going. Accelerando probably falls into that category, Blindsight would be another, Dune.

> As i see, the current science is more rigorous because people are producing lot of crap

Good, grief. No!!! It is a way of managing uncertainty and saying something with a precision that is available at a given point of time.

> How many discoveries are being overridden by new discoveries coming from future ?

This is beauty/and USP of science. Every scientific proof is always open for scrutiny and revision in light of new data or discovery ( tenants of falsifiability kick in here). That is, it tries hard NOT to be dogmatic by being provisional. For example, science says that we are confident Higgs Boson exists "accounting for one-in-a-million chance on the contrary" ( 5-sigma).

Let me flip your argument on the converse; success rate at which we could make ground breaking theories [ like evolution, theory of relativity , uncertainty principle ] ( which is standing the test of time for extended period of time) using the scientific method is sheer staggering and amazing. The methodology has accelerated our progress and understanding by leaps and bounds which no alternate system has managed to do so, so far!

> The amount of data accessible to the people in the past is a lot more when compared to current.

I lost you completely here. Can you please elaborate and the rest of the paragraph.

If on the contrary, the Monte Carlo filter I routinely simulate might just be the most insightfully entity I have encountered ).

> The division between religion/science is very small

Epistemologically they are apples and oranges! Falsifiability is not applicable to religion nor is it is provisional and routinely advocates absolute (and imho dogmatic) reasoning!

about (2): Streaming of copyright-protected media is generally considered legal, only copying is not. But it's claimed that streaming a file to the flash-player is actually "progressive download" and hence falls under illegal copying. (of course for purely technical copying between buffers, temporary files, ... there's even an exemption in the law (§44a UrhG), but that does not stop the lawyers from trying this reinterpretation).

About "gladii": The most interesting thing are the crosslinks between the companies involved. The company that claims to hold the rights to the porn is "The Archive AG" and the company that claims to have determined the IP addresses of porn-consumers is "itGuards, Inc". Normally the expert-witness should be somewhat independent of the plaintiff, but in this case the websites of both parties have been put on by the same user on the same shared webhost: wix.com (funny enough "wix" in German is a homophone of "to jerk off"). (details: http://blog.kowabit.de/porno-sein/). Also both companies seem to be founded within one week in March 2013, possibly on purpose.

Then maybe another interesting thing about these special "Cease and Desist" ("Abmahnung") letters in Germany: As someone has already mentioned, they have been invented to lower the workload of the courts, so that they don't have to deal with trivialities (basically between businesses, mostly used for/against wrong claims in advertising).

But the crucial thing is: The "fine" the receiver has to pay only is allowed to cover a certain aspect: The actual damage (here: possibly $10 for a porn-movie) and expenditures that the rights-owner had to pay to the lawyer. So if a nice lawyer sends out 100'000 cease-and-desist letters at a flat-rate of $10000 in total, you'd only be allowed to "fine" the receivers $10 for the porn-movie + 10 cent + postage or so. And if the lawyer "fines" the receivers $100 per rights-violation, he technically would have to bill the rights-owner 10 million dollars, even if the cease-and-desist doesn't have any merit, every single receiver would ignore it, and a judge would through the case out. Unfortunately there's no way to force the lawyer or rights-owner to let anyone know about their contracts, but sadly this makes almost every "Abmahnung" an invalid one, even though no one can proove it.

> Is this is implying that if you make an investment choice for personal reasons (maybe invest in a family business) and the company returns 10% rather than 20% that you could have received from a different investment that you have lost 10%. And that you have made the world poorer with that choice. The logic seems a bit hokey to me.

The idea that in that circumstance you've suffered a loss is the concept of the opportunity cost, one of the most basic ideas economics has to offer.

The idea that by doing so, you've made the world poorer is on less firm ground, but it's not exactly arcane reasoning. It's the same logic that backs the claim that high-GDP countries are richer than low-GDP ones -- they have more money. The general idea here is that if you start with $812 billion, and you turn it into $755 billion, you've lost money ("become poorer").
Paragraph N is actually valid reasoning.

Although, as with anything worth discussing, its not quite as simple as that.

If you invested in a family business that returned 10% instead of 20%, then you haven't really made the world poorer, you just haven't made it as much richer as you could have.

The other side of the coin, though, is that an investment has to be measured in far more than just dollars.

Investing in that family business might very well make you happy. And the happiness might be worth those 10% gains that you are forgoing.

> It does return the correct value for sin(π) though (you gotta call __sinpi(x / M_PI) if you don't want to return -8.74e-8 or some ridiculous value).

This is ridiculous. Your calculator (most calculators) cannot apply sin to π, because π is not representable is their system (typically base-2 or base-10 floating-point).

What you have done here is make sine worse for all values, including the representable value closest to π, in order to obtain what you think is a cosmetically satisfying result for the latter. Note that seeing the closest representable value to π does not mean that the user intended π. Perhaps the user obtained this value as the result of a computation and it's a coincidence. Or perhaps the user really wants to know what the sine of 0x1.921fb54442d18p+1 (the double closest to π) is. Hint: it is not zero.
