You need a teardrop shape to get rid of that vacuum, which is why every type of bird, fish (and man-made counterparts, airplanes and submarines) are basically composed of tear drop cross sections - to minimize drag. You could make a really flat dome such that it was sufficiently teardropped in all directions, but it's not really what we think of as a dome.

    We still don't have a cure for it, so you are just telling the person at present 'Hey, you have Alzheimer's! Good luck with that!".

    Knowing allows planning - for the person (as best they can), their relatives, friends and people at work. Consider the alternative. You have a person who is slowly but surely (although often with periods of lucidity) losing their memory, their judgment, and acting in increasingly inappropriate ways. This is a serious problem for all concerned.

    If you know you have Alzheimers, you can make some appropriate decisions. It is a degenerative disease with a likely timeline. For one, you can set realistic goals - goals within your future capabilities. You can start wrapping things up because you know your time of being effective is running short. You can start figuring out who will make financial decisions, because eventually there will be con artists preying on you. And if you don't like the idea of not remembering your closest family members, potentially causing rifts with family members for no good reason other than your brain is dying, acting in a sexually inappropriate fashion, losing control of bodily functions etc... you can choose to end it while you still have the mental capacity to carry it out.

    If you are a family member/friend you can realize that their brain is faulty and going to get faultier. They are literally not the people you used to know, so you can't expect them to act the same way any more. They may treat you badly and not realize it. If you liked them before, you can choose to remember them in that way rather than the demented person they become. There are a host of other things to get out of the way, powers of attorney and stuff like that. It allows you to plan, too. It won't get better, it will get steadily worse.

    Another thing - as the boomers age there are going to be a lot of people with Alzheimers in positions of power - government and business especially. They will make bad decisions that affect a lot of people. Think Reagan with his finger on the nuke button, not being in his right mind any more. Jobs will be lost and shareholders will lose money as a result of demented CEOs. Mandatory Alzheimers testing in these positions (and candidates) past a certain age would certainly prevent a lot of problems.

    Generally, people with Alzheimers are going to be driving cars, operating heavy machinery and inadvertently kill people. Enough of them and it's going to cause serious problems. Perhaps the problems will be obvious and pervasive enough that those in power acknowledge it, even though it conflicts with their generally narcissistic desire to live forever and not be reminded of their mortality, let alone be constrained against their will.

    I'm not exactly sure when the trend started but at some point this attitude of "make a good design, then make it fast" came to prevalence.

And on my machine that would have been top of the line in, oh, 2005 - it runs those things fast enough to suit me. If it's fast but unusable, I won't run it.

    Enterprise is out of the question here.

    "Enterprise Class" is marketing gibberish designed to produce FUD. There are many, many databases used in a typical "Enterprise" that do not need to scale out and never will. In fact, I would bet more companies have need of this sort of database than the other. Every company has need of databases that cover internal control issues - accounting, inventory, payroll, industry specific stuff. These do not need replication. (Often they just need a better backend than MS Access.)

    The primary concern of these databases is data integrity - that is, that the RDBMS does not treat your data like junk, and that you can constrain your data however you require. PostgreSQL has a well deserved reputation there. The secondary requirement is flexibility - can you get at your data and do what you want with it to learn more about your business or save you time? With flexibility in querying and a wide range of languages for stored procedures, PostgreSQL has an excellent reputation here too. Speedwise it is also no slouch.

    Besides, if you really need to scale out (now or in future) there are third party solutions such as Slony, and now the PostgreSQL team is working on simple, built-in replication.

  14. It's the product, not the marketing on Linux Foundation Asks Who Says "I'm Linux" Best · · Score: 1

    Great product, shame about the marketing. That's why Canonical / Ubuntu is so important.

    Important for... the marketing? I disagree. It's the product. I must have tried to convert to Linux at least 5 times, and most times I tried several distributions - Redhat, Debian, Mandrake, SUSE, PCLinuxOS, Fedora, Ubuntu (in the early days), as well as the small distros like DSL and Puppy. I did not find any of them to be really livable at the time I tried them. Ubuntu Feisty was the first time I found a distro that did things acceptably enough for me to live with, even though because of its popularity I really did not want to like it. Canonical/Ubuntu is important because they have lowered the bar to Linux adoption through working on ease of use issues and through their newbie friendly ubuntuforums.org. The emphasis is on great product first, the marketing will take care of itself.

    I think in many cases the next logical adopters of Linux know what Linux is and why they should adopt it. They have seen friends they admire use it and envy the power, or heard it talked up in online forums. Marketing is not needed for them. They know that learning Linux is an investment - more work up front that will pay back that effort and more in the long term. Chances are good that they have indeed tried it before and failed. In many of those cases, they will try it again. Why? Windows is like the abusive alcoholic boyfriend - the user is the battered wife that keeps coming back despite all the flaws because he's the devil they know, and it's less work! But every so often, Windows will push people to their limits - a malware hosed computer, having to pay the MS tax, whatever.

    Even those who have tried Linux, fail and vow to never go there again will be tempted to do so again out of pride when they see someone with less technical skill embrace linux. (If that klutz can make it work, why can't I?)

    On a related note, a pertinent question to ask in terms of marketing is "What sort of user isn't currently using Linux now but would find it useful? How do I reach them?", and more importantly, "What sort of user will cause many other people to use Linux? How do I reach them?". Asking that will provide most bang per buck.

    I think in a lot of ways the product is there and the right people are adopting it. Hacker kids embrace Linux because it is powerful and they have unlimited time to make things work. Entrepreneurial kids (and people in general) embrace Linux because they have time and ability but lack money, which allows low-risk business experimentation. Even if they don't start companies, they appreciate the low-cost aspect of Linux. As those two groups of people move up the IT ladder, the corporate ladder or bring new corporations into being, Linux will infiltrate the corporation. As both groups of people install Linux in the homes of their families and friends, the install base will also grow as people are initially exposed or forced into using Linux, then become familiar with it and resistant to change.

  15. Re:No! Wrong wrong wrong!!! on Brain Decline Begins At Age 27 · · Score: 2, Informative

    Interesting post - relating it to databases. From what I have read, IQ has two main components, gC and gF, standing for Crystallized and Fluid intelligence. Fluid intelligence is raw problem solving ability, crystallized intelligence is the database aspect you are referring to (tables, the data in the tables and the queries you have built up over the years). I guess fluid intelligence is more the ability to create the right tables, fill them up with good data, and creating meaningful queries.

    Fluid intelligence is known to peak in young adulthood and then steadily decline. Crystallized intelligence gradually rises and then stays stable through most of adulthood, declining after 65 on average. I think practically for many things, the increase or maintenance in gC offsets the decrease in gF.

    I notice the drop in gF type things in myself - I certainly don't have the superior reaction times I did in my late teens. If I play an FPS, I have learned to make up for that by playing in a more patient manner and playing the percentages - picking my battles. It's harder to say about the reasoning, I haven't noticed much decline yet. But I certainly notice having the larger database of information and more queries, and more refined queries of gC, which enables me to solve some problems much quicker than previously.

    Eventually though, it's downhill and I hope to anticipate that and lower my expectations accordingly.

    IANAB but it seems unlikely that all of these internal things would be changing while the outside stays practically identical. Someone correct me!

    Sensory and intelligence apparatus can change a great deal while a creature superficially remains the same. There may be others (e.g. efficiency), but those are the ones I immediately think of. I suspect those things are harder to get right, so they take longer for natural selection to do its thing.

    Consider a mould of Isaac Newton versus early man. Newton's head was a bit bigger and his body a bit weedier, but all in all, pretty similar. Or perhaps more to the point, consider a WWII or 1950s submarine versus the latest iterations of US submarines, or an F-22A versus an F-15 or F-18. Superficially they are very similar, because an object that spends all its time in a fluid will need to be designed (or will converge on a "design" through natural selection) to move efficiently in that fluid.

    However, the power plant, avionics, stealthiness of later iterations of military vehicles are going to outclass earlier vehicles by a huge degree. Pitted head to head, the former submarines and aircraft will only be capable of lucky kills. Getting back to the example of the octopus, we have no way of knowing whether the earlier version of octopus could change color at will, spurt ink, or figure out how to get food out of a bottle with a cork in the top.

It's like buying an exercise bike, thinking that you are going to suddenly start a regular program of exercise in your house, and stick to it, and that the exercise bike won't end up a dustgatherer like every other non-gym installed exercise bike. If you want to get fit from cycling regularly, I can think of no better way than moving close to work, selling your car, and buying a bicycle. It's considered a little extreme but if you can do those things before the buying the bike thing, it works, guaranteed.

    Linux is much the same way. You will become far more proficient with Linux using Ubuntu every day as your main system than you will having installed $Uberl33t_Distro on some spare machine or dual boot only to gather dust. The latter didn't work for me, that's what I did for my first 5 or so failed attempts to switch. Using $Uberl33t_Distro only made it worse - the culture shock of seeing just the bare X screen thinking "now what do I do?" only makes it worse.

    The way I switched was to first recall every program or process I used my Windows PC for. The next step was finding FOSS apps that exist in a single $Distro that did the same things and had Windows binaries. After you have worked through all of your applications and are now happily doing them in FOSS programs inside of windows, you are ready for the next step. If you can't get an app that does what you want, you will have to either wait or see if there is a linux-only app that does what you want, which you will test in a spare machine. Alternatively, if it is a game that is your app, you may need to set aside one computer as a gaming machine with ONLY that game on it, running Windows (I found it easier just to learn to like the better Linux games). Once you are sure that all the things you use your computer for will work in a linux environment, then and only then you are ready for the next step.

    Buy two new HDD for your machine to install $Distro on - one to use and one to keep as a backup. Buy an external USB HDD case for your old HDD to copy your files over. Catalog your hardware and google each item and linux, to see if there might be a problem. If there is, note the alternative hardware that works. Schedule a week off work. Maybe longer. Install $Distro (I recommend Ubuntu simply because it worked for me, the repos are everywhere, extensive, and the user community is without par). If some hardware does not work, give yourself a day or two to troubleshoot it, otherwise be prepared to buy your way out of trouble.

    Migrate each application's config files etc. Google is your friend here. After everything is working properly, back up your HDD using something like partimage, or maybe tar. Now, if you screw something up you can always wipe the slate clean without having to go through the monotonous process of figuring out how to get hardware to work, or hacking some obscure config files that you won't touch again. And at least you have a reference known working config file, should you decide to try and repair the config files yourself. You should also document the whole process - what you did to get each thing to work. You might need that again some day, only it might take a week (or never) to find that one helpful website or to chance upon the correct config instead of a day. You will also find it very useful if and when you do a clean install of the next distro.

    Now, use Linux in your day to day life. Google will be your friend, especially google with site:ubuntuforums.org. Proficiency will come as you set yourself goals of wanting to do something and googling to figure out how to do it. Every little experience makes you that bit more proficient.
