  1. Re:Religion and science are not orthogonal on The Vatican Invites World's Leading Scientists To Discuss Cosmology (independent.co.uk) · · Score: 1

    They are not orthogonal unfortunately because for religions to work they have to manipulate how people think. Science is really nothing more than a rigorous method of thinking and it routinely comes into conflict with religions on this point.

    Science and religion are orthogonal in that science tries to explain creation while religion tries to explain God's actions, motivations and expectations. Religion accepts observations of science because they are the mechanics that God set in motion. Science doesn't attempt to answer questions related to God because there is no evidence.

    Many religious people have no problem with scientific thinking. The big bang theory was proposed by a Catholic priest teaching at a Catholic university for example. Many understand that the passages of the bible are figurative not literal. Things needed to be explained in terms that pre-scientific shepherds and farmers could easily understand. If God were presenting his creation story today at a cosmological conference it would probably be far more technical. I'm betting on a multiverse, and that dark energy/matter is mentioned, hopefully explained.

    What you seem to be finding in conflict with science is politics. Politics can copt and use both science and religion as a tool for political ends.

  2. Traditionally God outside the universe ... on The Vatican Invites World's Leading Scientists To Discuss Cosmology (independent.co.uk) · · Score: 2

    Curious how they interpret genesis then. If the big bang theory is accurate, then a god simply cannot have created the universe. It all comes down to relativity: If the universe started as a single dimensionless point, then the gravity would have been so strong that time didn't exist. If time didn't exist, then there was no time for a god to create the universe.

    It is unlikely that the big bang presents any sort of theological problem for the church. The theory was put forward by a Catholic priest teaching at a Catholic university after all.

    Keep in mind that communications between two parties needs to be a least common denominator sort of thing. An all powerful God has to use concepts that humans can understand. The pre-scientific farmers and shepherds of the bible's day needed something a bit simplified compared to a modern astrophysicist. Perhaps if God were to explain things today we might have a genesis where our universe is created out of a multiverse. That would be closer to what I think the church argues, that God is beyond the universe, outside of it. Not simply in a different geographical part of it. Hence the ability to create space, time and the universe.

  4. Reliable box with macOS, MS Windows and Unix on Ask Slashdot: What Is the 'Special Appeal' of Apple Products? · · Score: 1

    As someone who comes from MS-DOS/Windows PCs background, I've never quite understood the appeal of Apple's products.

    I have an Apple II/C64/Mac/DOS/Windows/Linux background, both as user and developer. The advantage of Macs today are:
    - Reliability. With all the parts coming from the original vendor compatibility and drivers are not much of an issue. This also translates into security. Personally I have few problems on the PC since but I build my own from carefully chosen high quality parts. A more typical budget crapware laden retail PC is more troublesome. Most problems I've seen on the Windows side are due to 3rd party software, not Microsoft, especially drivers. Less 3rd party under macOS.
    - Compatibility. I can dual boot in macOS or Windows. Yes emulators are nice but for games and some development work a native OS is better.
    - Desktop Unix. Some tasks are better done under *nix. I've been using Linux since '94. However macOS provides a perfectly good *nix environment and Linux is pretty much relegated to headless boxes in a closet somewhere these days. The macOS GUI and macOS apps are simply better than their Linux counterparts.

    In summary, a quality reliable box with native macOS, MS Windows and Unix environments.

    Historically MacOS was superior to Windows through 3.x. Win9x was close enough but still inferior. Windows NT was where Windows became superior, it was inexcusable for Apple to take so long to get something like MacOS X.

  8. I have no idea where you're getting 300L a day. A human only needs around 1l of water a day to survive.

    No, active adults need about 3L not 1L. So with this device producing about 2.8L it could sustain a single person. Things get complicated with activity levels and climate, and water in food counts towards the total.

    The 1L per day figure is life raft level rationing where you are sedentary and either rescued from the sea in a few days or likely to die so additional water is unlikely to change the outcome.

    Poor(er) people think that way. If you're rich, you have the luxury of getting what you want, and not having to have the cheaper stuff; of not having to choose between a good product or a good holiday/eating out more/clothing and feeding your kids. Poorer people don't have that choice. And it's not as if the elite/rich people are doing all they can to lift poor people out of poverty. I'd not blame "consumers" for trying to stretch their money as far as possible.

    That the impoverished have a more valid reason does not change the fact that businesses that go the offshoring route are rewarded by consumers, that consumers drive offshoring process.

    Also this was largely driven by the middle class, as most things are. Keep in mind that this trend started long ago when it was far more likely for a HS educated person to find a job that offered a living wage.

    You're oversimplifying a complex issue to blame the working class. Americans shop on price because we're desperately trying to maintain our standard of living in the face of declining wages. Those wages are declining because of globalization and automation.

    Globalization is in part a result of the consumer's willingness to consider price above any other consideration. The consumer drives the offshoring process through their choices, their "tragedy of the commons" logic. CEOs may be greedy but it is sales that satisfy their greed, and it is consumers who decide whether offshoring improves or hurts sales.

    Walmart's slogan nails it: You're not destroying Unions and plunging the country into the worst income inequality since WWI; you're saving money, living better.

    The thing is Walmart is not creating that behavior, they are capitalizing on that pre-existing behavior, they leverage the pre-existing behavior.

    We are also talking about a current situation that is the result of consumer behavior that has been going on for 40 to 50 years. And now with online shopping it is easier to find US made goods than in recent years.

    If consumers wanted to demonstrate a preference for local products they have options. Such a trend would be recognized. That is why you find various "greener" products at the grocery store nowadays, consumers started voting with their dollars and stores responded.

We reward the supplier that offshores and reduces quality. If we consumers showed a preference for local goods and/or higher quality goods that is what Walmart would stock the shelves with.

The hardware I am speaking of are the chipsets for the various types of I/O, not the BIOS itself. BIOS is largely irrelevant once the host OS is running. The host OS may look at current BIOS setting and respect a user setting but it is under no obligation to do so, BIOS can not enforce any limitations on the host OS.
