Math and Science / Re: Buoyancy
« on: December 14, 2012, 03:44:11 am »
You can actually test this for yourself in real life. What happens with a perfectly rigid block is that there's a differential pressure. The top of the block has the weight of the water on it, the bottom of the block has only the static pressure of the container's bottom (which is precisely equal in magnitude to the force exerted downward) , and the sides have evenly distributed pressure all around. There's no net upward force! The block will stay on the bottom unless water somehow gets underneath to exert a buoyant force. Remember that archimedes' principle only applies to an object suspended in fluid.

I meant, the resulting cells would be a QR code :P not that it calculates the data for a useful one.

In that case, probably not without a truly funky neighborhood and ruleset.

I wonder if you could make a CA that generates QR codes....

Sure, some cellular automata can make QR codes. They're turing complete. Finding an automata that generates QR codes in some non-simulation way would be difficult though.

By whom? There's no global supergovernment with the power to punish. The closest thing is the UN and they *don't* have that power.

81
Wrong! The treaties have no binding effect AT ALL because the governments involved have no jurisdiction over the entire world! The only way that the treaties would have effect is if EVERY country had a say... Why? It's called the World Wide Web...

Does this mean that participating countries won't abide by said treaties? Not at all. They will abide... but until ALL the countries of the world make a GLOBAL law regarding the internet and treaties involving the usage there thereof, the treaties can be broken easily by participating countries...

What? Whose jurisdiction would such a global law fall under? There isn't a global government to HAVE laws in the first place. That's why international law is such a vague field.

As for your point that the internet is a global network, that's irrelevant. Roads are also a global network. They can still be regulated by every government where they fall within its borders. The only difference with the internet is the question of "where are the borders?"

What shoud be regulated is terrorist attack plans (and by terrorism, I don't mean Syrian Government's definition of it, I really mean 9/11-esque stuff), scamming/phishing/counterfeit item sales, illicit drug dealing, death threats and any plan to physically assault/put in danger the life/lives of someone or a group of person. Anything that is already illegal outside the Internet, kinda.

This comes back to the borders question as well. Who has jursidiction where? Take this site, for example. It's a site catering to a fairly international audience, served on an international cloud, administrated by a group with two different nationalities, started by a person with a canadian nationality. Whose laws apply here? At various times, you could point to either Canada or the US and easily make arguments for the other.

Secondly, those "real life" laws are precisely the issue. The methods governments have in real life don't necessarily apply online, which is why they're modifying their laws to reflect the internet better.


82
And yet, the government does not have a right to regulate the interwebs because it is not public, and it is not owned by anyone...

Wrong. For one thing, there really isn't a conception of public and private internationally. What there is are government granted rights according to a country's internal laws, like I said before. Secondly, governments are explicitly tasked with regulation of their resources, even private ones. You can't buy a bunch of land and mine it to make illegal explosives, even if everything comes from your "private" property. Same thing applies to the internet, except this isn't a law or even a recommendation thus far. It's an optional standard.

83
I'm not saying that government shouldn't have power... I'm saying that government should not attempt to GAIN power for the sake of gaining power...

It's not "gaining" power to say you have claim a right you already possess. I think you're misunderstanding the position of governments and the powers of the ITU.

First of all, governments have every "legal" right to do pretty much whatever the heck they want on their territory, so long as it doesn't violate human rights. Now, the UN has declared that everyone has a right to protection against "arbitrary interference with his privacy." All of the UN agencies uphold this view, including the ITU. Note that this is an essentially meaningless right. For one thing, all that's necessary to get around it is a legitimate reason to violate your privacy. For another, the UN and all of its component agencies have no legislative power. None. The UN can make recommendations and set standards, but it cannot change the laws of any of its member countries unless they agree to the laws for themselves. The UN, and hence the ITU, fundamentally cannot regulate the internet. It has no power to do so.

All of that said, nothing prevents any of the member countries from regulating their own networks unless it is their own internal laws. They have every ability to regulate their own portions of the internet as and they've had this power from the beginning!

Finally, the meetings won't be over till the end of next week, but all I've seen of their schedule is that they'll be putting out standards. Let's say the worst happens and the ITU edits the treaty, which is then ratified in the US, (or wherever) and becomes a law. Well, it doesn't overrule any other laws in power and legally, the US government can't do anything more than before. As for the question of them using extralegal methods, they already do.

These talks are only really important from the aspect of showing how the international political community is looking at computer networks. Beyond that, it's a lot of hype over nothing.

Site Feedback and Questions / Re: [code=
« on: November 28, 2012, 03:11:07 pm »
I wanted to know what is up with code tag.  For me, whenever someone writes
Code: [Select]
[code=XXXXX] it always just shows as
Code: [Select]
Array  But other people say it actually displays correctly for them still.  So do other people have this problem, or am I just crazy? (Also, if i'm not, why would it work for some people but not others?)  (And what's the problem?  because it looks like a bug really)[/code]

You can use the [nobbc][/nobbc] tags instead of code brackets if you need to print bbc tags.

Example: [url]http://www.google.com[/url] vs http://www.google.com

News / Re: A new z80 calc... in color?
« on: November 09, 2012, 01:57:46 pm »
A driver would be necessary no matter what the system is like. Even your computer with a fancy GPU has a screen driver to handle the low level hardware management. It's also not that big of a difference, since even the current z80s could handle a color screen with a proper driver, albeit slowly. The difference is speed and cost of production. Rewriting the OS in ARM/C, debugging it, and then making sure a new hardware platform works well with the OS is expensive. I would not be surprised at all to find that this calculator is a derivative of the Nspire for no other reason than development costs on TI's end, especially considering that any production costs they have are passed onto the consumer at a steep markup.

Math and Science / Re: Integration by Parts
« on: November 07, 2012, 07:36:00 pm »
Why is integrating so more complicated than deriving? :D

In general, it isn't. With the problems you're working with, it's because integration maps functions to functions of at least the same class, whereas derivatives map functions to functions of at most the same class. (In other words, the same basic reason that division is harder than multiplication).
