  1. How sudden was the sea level change? on Global Warming 5 Million Years Ago In Antarctic Drastically Raised Sea Levels · · Score: 1

    The article abstract doesn't reveal how sudden the sea (eustatic) level change was, only dating it to a wide interval of time. Other research on more recent climate change gives time scales of decades to a couple of centuries of large change. 5 MYA Pliocene geography was different than now. The land bridge connecting North and South America hadn't fully formed yet and so the warm equatorial current could get into the Eastern Pacific. The dynamics of cooling would be different although the layout of continents was well on its way to cooling the global climate overall. 20 M or about 60 feet of sudden eustatic sea level rise would drown most cities on the coasts of the world. If this happens suddenly, within a couple of decades, the effects would be very hard on us.

Get rid of the expensive backend which is only there for the benefit of advertizers, distribute it regionally with outler access, and make the friends's list the only global thing. Face Book as the global entity would be much cheaper to run and the small regional CMS much less in need of costly support. To punish free users of the current model with ads that you have to pay not to see is just another businessman scam. If the model is to reduce the cost of running a social media service, then do away with the global CMS.

    The global CMS is why the UI for Face Book is so crappy and inflexible. The impetus for its design is not ease of use by users but access from FB's investors to the "privacy", not, of users. Do away with the problem by running the whole thing more cheaply and by doing away with the investors, or the need for expensive investors. Face Book doesn't need to be as capitalized as it is, another business scam. It isn't as local as a blog, even though most blogs have a better UI now, and you and I don't care that its backend can support more than 1 billion users when you and I only care about a few hundred at most and only three or four at a time. Do away with it, it is unnecessary. Shortly its investors will figure this all out and leave. Then it can be done at a better scale and for cheap. No need for a Premium service.

  4. Re:Diet and laziness on The Man Who Convinced Us We Needed Vitamin Supplements · · Score: 1

    In fact the true fault might lay with business cutting corners for profit and causing nutritional degredation of products, if not outright introducing toxic additives.

    And supplements are also just another profit scheme as well, and the problem is that they might be made in forms that the body is not well adapted to use, or it might be the wrong form or even a dangerous form of the supplement, vitamin or nutrient.

    In addition, most people assume that the FDA is there to protect them against fraud and remedies that lack efficacy or pose unforeseen risks, but it can't do so. The reason is that it is underfunded, intentionally so, by Congress to enforce law designed to protect consumers, and like most agencies of the Federal government, it has a built in conflict of interest that either the business people have too much direct access to push their agenda, and the agency is charged with both regulating them and promoting the interest of the industry it regulates. Most cabinet level agencies of the government have this flaw and the problem gets worse when the special business interests have greater access to the Congress, like they do at the present time.

    And so it is fashionable in some corners of society to blame the problem of abuse on individuals, as though we have conscious free choice as it that was a faculty granted us by the Bill of Rights. But the world we live in is one of subtle subliminal messages skillfully designed by the advertizing and public relations departments of corporations that do business here and also their trade and lobbying organizations. These deceive and mislead otherwise sapient beings who think they are the masters of their own decisions, and the perpertrators of the propaganda know otherwise. People who push the myth of responsibility and free conscious choice of consumers in such an environments are either naive or marketers and propagandists who know what they are doing.

    The example that I love to describe, because it is so deceptive and cynical, is the American Beverage Council campaign to defeat state and local inatives for limit sugar in soft drinks, really high fructose corn syrup, which is a major contribuiter to obesity and diabetes. I have seen two ads, one is less objectionable and claims that the beverage industry is trying to change what it does to address the concern, but the second one toutes the myth that consumers have conscious free choice and that they are equipped to decide what to buy and to not have government interferrence. Sounds good, untill you realize that the beverage industry has the upper hand in the propaganda war and can create subliminal messages that contradict rational health concerns. They do this for the same reason every business resists changes, They are locked into their chosen business model for a time, that includes the price of sweetener, and the number of people who get sick and who die as a result is a risk of continuing to do business until the business model can be changed,

    The naive, "responsible" model of human choice, that we are aware of everything we decide, parallels the equally naive Christian model of morality in which we face a conscious choice as compared to the standard given us via upbringing with a moral authority. It is "rationalistic" and conscious, which is why the Brave New World, not of drugs, but of the unconscious is really still very frightening to some people. They despirately want to believe that the subliminal and unconscious don't apply to them, or they might push the myth because they want to use it to control others in turn. That is what the Beverage Consul ads are about.

I gather that the primary article is suggesting gamma ray bursts within our galaxy and before 4.6 BYA as the source for most of the heavy elements in our solar system, more precisely, the terrestrial and some meteoric abundances. It is possible that when galactic black holes have lots of matter to consume forming quasars, that the energy is high enough in the ejected matter in their polar jets, note M87 in Virgo, that heavy element synthesis is possible and at a greater efficiency than in supernovas. The problem with GRBs is that they must be pretty rare in one galaxy and so to cite them as a major contributor tp heavy element synthesis might be problematic when more common but lower energy alternatives might be available.

    I don't know if heavy element spectra have been detected in quasar jets, or if they are sen in the light echos from GRBs. It may be that the energies are too high. Too much radiation and neutron flus would photodisintegrate heavy atoms. The flux would have to be just right.

Even though I worry about running Windows because of security problems, if it is what I had to use, even for a short time, I install cygwin on it just to have a familiar POSIX set of tools, and when I get annoyed with the clunky Windows tools I open an xterm and use familiar *NIX commands.

    I am not an EMACS user. This was a career decision made long ago. If it's Unix, it has vi. It almost certainly doesn't have EMACS. And I didn't feel like carrying a tape everywhere with me.

    I have long since avoided editor flame wars. It is useless to criticize people for their choice of either vi or emacs, You are right, the choice is often a matter of personal history, in fact my first exposure to *NIX editing was ed(1) and then(ex). I did system admin. and you are quite correct that vi was much more likely to be available than emacs, although today's systems having access to more ram, it is no longer much of an issue, even in an entirely ram based system. There are many people who are perfectly fine with using vi alone for system admin and development. Initially, I had trouble with the old modes of vi, but that is no longer an issue in vim.

    Or, there used to be a way to use vi in line mode, and I'm ok with that too.

In the case of a Solaris system that wouldn't boot into full-screen mode, I had to edit some system file using this to get the system to come up fullly. Emacs wouldn't work and neither would vi full-screen mode.

Adobe has already done this for subsets of its Photoshop functionality and you are right that Gimp and other open source alternatives are playing catch up. People may say the same thing about MS Office vs. LibreOffice, in fact porting the former to all these new devices might be what keeps Microsoft from going out of business.

What we did was to write a library with function pointers so that we could encapsulate methods and classes the same way you do in C++, but the discipline was all our's in ANSI C, so we had structs and pointers. I was able to act as a sounding board and tester, so I saw the code and used it.

They might be more sensitive to being asked to be "flexible", meaning the mgr says "Do it this way, because I said so.". The issue is the amount of time and effort it takes to master new tools on short notice, and that is related to the lack of generality and ease of use of tools in an industry that has a ways to mature. Managers often either don't understand the effort it takes to become skilled, because they often haven't achieved that level of skill, or they don't care, looking up the chain of command for recognition rather than respecting the level of expertise they have working for them. This is not really all that unique to programmers. All kind of creatives have faced this problem over recorded history.

    I had been a programmer of legacy languages and scripting tools and was suddenly asked to support java and a java IDE under development. I balked, and I didn't come to the reason why until much later. It wasn't that I could't learn java, but due to the fact that the language is very wordy and the libraries clunky and the stream of debugging data I would have to deal with is very hard on a visually impaired person. I have low acuity in only one eye, blind in the other, all I have is about 20/70, and the quality of the data coming out of the development version of the software I was asked to support was so compact and busy that it was nearly impossible for me to read. It wasn't just a matter solved by large fonts, but the use of camel text in a very cramped, poorly formatted, dump was very difficult.

    A visually impaired system administrator I met later. flat out asserted that java was not accessible. This is quite apart from the complexity of class libraries, which is daunting on its own. I think that most programmers would agree today that java is well past its prime with better languages around. Even javascript, by being able to encapsulate frameworks so well, and languages like python are superior. Had I been aware of the disadvantage created for me at the time by that manager's decision, I would have sued the company under the ADA. In retrospect, I have a clear case. I understand that lots of shops have a legacy investment in java and must maintain java code. It is still widely used, but for me it is not a happy environment to work in. If I choose to get snarky about it I could say that like PL/1, Java is not a better C, K&R had a wonderful simplicity and the standard C library was concise, but I could call java "security through obvescation" which is why it was so appealing to corporate IT departments, but I am only speaking for myself and if people use it, fine, but it is not for me.

Up until the past few Windows releases, you got little help from the OS to troubleshoot failures and if you had the sluthing skills to use what little was there, you could probably have used *nix command line tools and the log files to do *nix system administrationm, anyway.

    Applications on *nix in a GUI are often based on command-line versions that have options removed, simplified, so they can be easily used from the GUI, and along with that trend developers aren't maintaining man pages when they should because they think that unless the documentation is in a web page users wouldn't dare open up a terminal and start issuing CLI commands. I'll bet that most Mac OS users have never opened terminal and read man pages even though there is a wealth of information there that they could use to fine-tune and diagnose their systems, writing bash scripts if they need to. My son came to me one day asking about python on Mac OS X. He knew it was there but was unsure how to use it. I opened terminal, looked at the man page and ran the interpreter for him, and then I showed him how to write source documents, compile and execute them.

Current Linices with GUI will run live off the DVD on machines that ran Win XP but are too small to run any newer Windows versions, and they boot much faster.

What I like about *nix systems is that the low-level complexity is really just below the surface and the number of years it has been tested and debugged is a hedge against the failures possible with new and not time-tested GUIs like Unity. So empire builders can mess up the interface as much as they wish, a huge win is to leave the legacy alone and give me access to the older stuff.
