    Vendetta Online has a system of license levels which unlocks content, but combat success is 90% skill and 10% equipment (after the first couple of levels which probably take an experienced player less than an hour).

I use ubuntu because it is my first linux experience that I used for more than a week, and because of the enormous amount of support, stupid forum questions with non-stupid answers, etc. It helps if an answer to a problem is directly applicable.

    Genuine question: Besides the desktop environment, are there any real differences between all the Debian derivatives?

  9. Re:No, because they are not compatible on Should Nuclear and Renewable Energy Supporters Stop Fighting? · · Score: 4, Informative

    According to the wiki on Pumped-storage hydroelectricity (PSH), 'PSH accounts for more than 99% of bulk storage capacity worldwide: around 127,000MW, according to the Electric Power Research Institute (EPRI), the research arm of America's power utilities.' Since in pumping the size of the reservoir is not the limiting factor, but rather the throughput of the pumps, this means that PSH can be used to store the daily output of 127GW worth of power plants. Britain's consumption is 35.8GW on average, and 57.490GW at peak (http://en.wikipedia.org/wiki/Energy_in_the_United_Kingdom), so the global installed PSH's could easily absorb the UK's production.

    In the UK, however, there seems to be only one plant (http://en.wikipedia.org/wiki/Dinorwig_Power_Station), costing 425M GBP in 1974 capable of absorbing around 1GW worth of power, so nowhere near 50% of base load, so it seems that PSH costs around 425M/1G = 0.5 pounds per watt capacity. Apparently, a new nuclear plant costs about US$ 5,339/kW., or 4 pounds per watt capacity, while windmills cost around 1-2 pounds per watt. So, assuming enough sites for PSH can be found, the costs for power storage capacity seems to be 5-25% of the cost for generation capacity.

    According to the wiki, "The stalling of the UK nuclear power programme in the late 1980s and the coincident "dash for gas" increased the network's ability to respond to changes in demand, making the use of pumped storage for day/night load balancing less attractive. As a result, a similar facility planned for Exmoor was never built.[2]"; so it seems that at the time the demand is what limited PSH construction, not cost or environmental factors.

    I would be fine with you not wearing a seat belt, as long as it does not affect me when you get into an accident, including:

    - my taxes don't go up because you are now a burden on the emergency medical care system
    - the road is not closed off longer because the accident is now more serious, leading to more traffic jams.

  13. Re:Sounds like a problem... on How Big Data Is Destroying the US Healthcare System · · Score: 2, Informative

    Positive rights such as public safety and national defense are different from the classical (negative) rights that the parent referred to. Classical rights (e.g. the negative rights listed in the US Bill of Rights such as freedom from censorship, cruel punishment, illegal search and seizure) do not need a government to enforce them, since without a government you wouldn't need those rights.

    Of course, the negative rights that protect you from the government are worth an awful lot without a bunch of positive rights which indeed need a government to enforce them, such as the right to life and property. The thinking of the Bill of Rights is that the (U.S.) government would naturally provide for positive rights such as the right to property (by enforcing already existing common law) and the national security (since fighting the Brits was the raison d'etre of the U.S. government); but that the government would need to be forced to provide for the 'negative' rights.

    Also, positive rights are generally political choices: how much healthcare, education, and public safety is reasonable and when is the cost (in dollars or liberty) too high? So, it can be wise to leave those to the political process, while the negative rights are best enshrined in the constitution and left to the judiciary; although it is easy to argue that by not updating the constitution to reflect such positive rights such as non-discrimination and privacy the US supreme court was forced to become more political than similar bodies in other states such as the German Bundesverfassungsgericht.

    You are wiser than most to realize that there is a distinction between Constitutionally granted rights and what many people are now declaring is a right.

    You are right in a sense, but I think you are seeing "rights" too narrowly. The distinction that is generally made is between classical, negative rights (the ones in your 'bill of rights') and the positive, modern, or social rights (such as in your "equal protection" clause and in many european constitutions and also in some articles of the universal and European declarations of human rights.

    The right to free speech is a "classic" (human) right. It is something between you and the government, and it acts as a prohibition on the government. It is a 'negative right' in that the government isn't forced to *do* anything, they're forced to not do stuff, like putting you in prison if you say stuff. The bill of rights used the phrase "congress shall pass no law" for a reason. The right doesn't mean that the government has to pay publishing cost for your newspaper, and it also doesn't mean that other citizens are forced to listen to you or banned from telling you that you're a twit if you 'exercise' your basic right. These rights can be "absolute" in the sense that they allow no exceptions, although it often isn't (the classical example being yelling 'fire!' in a crowded cinema) and in principle they cannot clash, since every negative right bans the government from doing something. The right to the freedom of the press and the freedom of religion do not clash: if you exercise your press freedom to say that not all Catholics are holy, there is no clash of rights, since the freedom of religion never prohibited you from saying that, it simply prohibits the government from establishing, favoring, regulating, or banning any religion.

    The right to healthcare (and education, housing, property non-discrimination, etc) are all "social" (human) rights. They are generally positive rights, where the government has to provide something for the citizen. These rights are never absolute, in the sense that it is obvious that no one can receive all the education, health care, etc that money can buy. Also, these rights can clash with each other and with the classical rights: my right to self-expression can clash with your right to non-discrimination.

    Sometimes, a right can be both 'positive' and 'negative'. For example, the right to "life" in the universal and European declaration of human rights (and implied in your declaration of independence) is mainly negative, in prohibiting the government of killing you in most circumstances, but can (and is) also interpreted positively as a positive duty to prevent certain loss of life and/or to investigate suspicious death. Similarly, the right to own property (e.g. article 17 UDHR but see also the 3d-5th amendment in the US Bill of Rights) is a negative right in prohibiting the government from taking your stuff (except through taxes, eminent domain etc.). However, it also implies a duty for the government to protect your property by banning and investigating theft etc, although the US Bill of Rights is phrased to exclude those duties by listing prohibitions against search, seizure, and quartering by the government, and does no list a "right to property".

    - Israel is still a very religious state, with e.g. no civil marriage (you marry before either the rabbi, the imam, the priest, etc, but no religion = no marriage and a mixed marriage means someone must convert). There is a minister of religious affairs and the state in waist-deep in a number of religious issues. Jewish religious schooling is mandatory in most schools. Citizenship is linked to religious/ethnic heritage.

    - Israel is a segragationist state, with a large part of its citizens treated as second class (palestinians, bedouin) and there are extremist groups that physically attack people and institutions who strive for more integration and dialogue (see: price tag attacks).

    - Israel is an occupying country, its army occupying a territory with over 4M people living in it. You cannot travel through Israel (much less live in it) without seeing the effects of this, in terms of checkpoints, barriers, and a general siege mentality in the population.

    - Israel is surrounded by countries that are either hostile, in a civil war, or both. Jordan is an exception but if you go through Jordan you come to Iraq (hostile, civil war), Syira (hostile, civil war), or Saudi Arabia (just hostile). This contributes to the siege mentality in the population.

    tl;dr: If you live in Israel, you live in country based on a tight coupling of church and state; you cannot go on holiday except by airplane; your children will face 2/3 years of military service with a good probability of serving in actual combat and occupation duties; whenever you drive over 100 miles you hit a wall (often quite literally); and almost half the people living in the area controlled by Israel are treated as second class at best.

    Also, the water needs to flow to bring cold water to the heat exchange. While the convection will cause some flow, powered pumps can make a lot more flow. And pumps by necessity have intakes and outflows, and these can be clogged.

    Of course, you can filter every intake in any way you want, and then the filters will get clogged. Which I'm sure is what happened here (I don't think the jellyfish made it to the actual heat exchange).
