When a software company has a financial stake in a media-delivery system or an ad-delivery system (even Apple or Google could easily be tempted by this), whether it's through ownership or numerous partnerships, then it must exercise extreme caution and self-control not to turn the product it sells to its customers into ad-laden remote-controlware. Remote-controlware built for the financial gain of ones's friends, instead of the interest of the actual PC owner (or the actual users), makes an OS inherently insecure. That is why Microsoft gave us scripts that could be executed remotely through Outlook (without the user's intervention or even without their knowledge). That is why Microsoft DRM protection is causing all kinds of problems for users and developers. And that is why Microsoft delayed for years before making a pop-up blocker standard in Internet Explorer.

    I have Italian as a mother language, and I speak English, Norwegian, and I am learning German. I can guarantee you that you cannot learn a language in a matter of weeks. No-way-in-hell.

    Just to be clear, I said 'twelve weeks or less' -- that's roughly the equivalent of three months or less.

    You must be a monolingual English speaker to say this.

    I am a native French speaker, but you're not too far from the truth in at least one thing. I'm the exception to the rule (that's why I was careful to qualify my claim with 'most people' -- not 'all people'). Even in my own native tongue when I was a toddler, I only said my first word a year late (they thought I was going to be mute), and even after I started speaking, I had all kinds of stuttering and pronunciation problems. The main reason I know English now is because my family moved from France to the United States when I was twelve years old. I seriously doubt I would have learned English with my natural abilities if I had remained in France and tried to learn it there.

    That being said, I've done my share of French tutoring in the United States and I've done my share of English tutoring for French natives who now live in the United States. And while I agree that most high schools are not very good at teaching foreign languages, a typical high school is not what I'd call 'proper immersion'.

    In the United States, any halfway decent University will give you some very effective language-learning classes (and even in the Summer, when their classes are just 12 weeks long, and more concentrated). As I said already, there are some things in a language that are more difficult for us to learn as adults, but as adults we also have the ability to learn a language more quickly than kids if we dedicate enough time to it. The key is dedication, persistence, and learning from as many sources as possible. A language University course requires that kind of learning, otherwise you'd flunk the course. Going to the country in question and living among the natives is also one other way (although, that should also be supplemented with other means).

    And even if you don't have the possibility to go abroad or to study this in University, you should still try to learn a foreign language from as many sources and from as many varied sources at the same time. This includes getting the tapes from multiple language schools for that specific language (personally, for French and for many of the other European languages, I strongly recommend that you pick the ones by "Michel Thomas". Michel Thomas doesn't have a perfect accent. And his stuff is not sufficient all by itself -- as he claims it is -- but his way of breaking down a European language and his way of teaching that language is the best one I have ever seen). In addition to that, you should get a foreign girlfriend (or a foreign boyfriend) who is willing to only speak that language to you (just never apologize for your mistakes and don't ask for corrections all the time, the errors are fine, it's just the constant correction-seeking and the approval-seeking that may drive them completely nuts). Also in addition to getting the tapes, (possibly) the girlfriend, you should also try to get some friends, some grammar books, a dictionary, multiple (beginner) books, some comic books, any cable television channel, internet radio, original foreign movies, and pretty much anything else you can get your hands on that was made in that specific language you want to learn.

    Learning a foreign language is not easy, it can not be just a burst of activity a couple of days a week, it requires lots of free time and consistent daily effort. It also requires you not to mind looking foolish, looking foolish is the only way to learn. Also, as an adult don't expect to get the perfect accent, some people can, and some people can't.

Now how many 2 year olds, 6 year olds, or 10 year olds, do you know that can do the same in twelve weeks or less?

    The truth is that with proper immersion, most kids will learn a new foreign language over a year -- or over several years, it's just that we don't really count their time -- the same way we adults count our own time (after all, we have things to do as adults, and them -- the kids -- the kids seem like they're wasting their time watching things like Pokemon).

Tell your own soldiers that it's perfectly safe. Deny everything for as long as possible. Label all the critics conspiracy theorists (not that this label is not sometimes correctly warranted). And watch your former soldiers drop like flies ten to thirty years from now.

    Do you know a little bit about dog training? Forgive the analogy, but dogs are pack animals just like we are, and when I use that term -- I mean no disrespect by it. But when a country does something wrong, you must come down on it immediately -- not ten or twenty years later -- otherwise your intervention will seem self-serving (or at the very least completely disconnected from the original event). And when one of your friends (or one of your family members) does something horribly wrong, let's say that a family member of yours commits a genocide -- well you stop him -- or at the very least you stop supporting him -- and you do that immediately. This ethics of "You're either for us, or you're against us" is the most retarded tribal thinking there ever was. This kind of tribal thinking is something I would expect from Iraqi or Iranian people, not from the President of the United States. When someone does something wrong, whether they're with us or against us, you come down hard on them. Same thing if our very own people have done those horrible things, we take care and punish of our own people for Crimes of War as swiftly, as transparently, and as fairly as we do it for others.

    ZDNet Zero-Day blogger Nate McFeters has asked the question, 'Should vulnerabilities be treated as defects?'

McFeters suggests providing bonuses for good developers, and taking away from bonuses for those that can't keep up. It's an interesting approach that if used, might force companies to take a stronger stance on security related issues.

    When I think of defects and total quality management, I think of Edward Demings.

    Edward Demings saw the problem of defects as a systems issue, not an individual performance issue. And his theory was that paying someone based on performance would have the unintended consequence of increasing the number of defects, not decrease them (Here is the list of Deming's 14 principles with my emphasis added in bold).

    Deming offered fourteen key principles for management for transforming business effectiveness. The points were first presented in his book Out of the Crisis (p. 23-24)[19].

    1. Create constancy of purpose toward improvement of product and service, with the aim to become competitive and stay in business, and to provide jobs.
    2. Adopt the new philosophy. We are in a new economic age. Western management must awaken to the challenge, must learn their responsibilities, and take on leadership for change.
    3. Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first place.
    4. End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move towards a single supplier for any one item, on a long-term relationship of loyalty and trust.
    5. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease cost.
    6. Institute training on the job.
    7. Institute leadership (see Point 12 and Ch. 8 of "Out of the Crisis"). The aim of supervision should be to help people and machines and gadgets to do a better job. Supervision of management is in need of overhaul, as well as supervision of production workers.
    8. Drive out fear, so that everyone may work effectively for the company. (See Ch. 3 of "Out of the Crisis")
    9. Break down barriers between departments. People in research, design, sales, and production must work as a team, to foresee problems of production and in use that may be encountered with the product or service.
    10. Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the work force.
    11. a. Eliminate work standards (quotas) on the factory floor. Substitute leadership.
      b. Eliminate management by objective. Eliminate management by numbers, numerical goals. Substitute leadership.
    12. a. Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility of supervisors must be changed from sheer numbers to quality.
      b. Remove barriers that rob people in management and in engineering of their right to pride of workmanship. This means, inter alia, abolishment of the annual or merit rating and of management by objective (See CH. 3 of "Out of the Crisis").

Showing kids the effect of the invisible stuff on their hands through the use of petri dishes and agar, both before they wash their hands and after they wash their hands, can be very educational. To make it more relevant to current events, such an experiment can easily be replicated with cheap tomatoes (usually those are tomatoes that have already fallen to the ground and been picked up from there) and tomatoes with their vines still attached to them (those types of tomatoes probably wouldn't have touched the ground, and hopefully the equipment and the pickers hands that handle them afterward would have been properly sanitized). To replicate the effect of a tomato with salmonella on it, you'll just have to spread some of your feces on it, wait, and then wash it with cold water -- so that the smears are no longer visible. You should get plenty of salmonella and many kinds of other good stuff on it that way. If your kid starts wondering how the feces (or the dung) got on the tomatoes, just take him to a farm where there are many cows, take some fresh hot soil samples for your petri dishes, look for where the water runs off, then take him to a tomato garden (or make him grow his own tomato garden in a flower pot), I doubt you'll be lucky enough to find a tomato field with cows freely roaming on it -- that would be too easy of a smoking gun.

    The next thing you could have him do is have him draw an epidemiological map, and make him try to find the farm(s)/the packaging plants where the contaminated tomatoes are coming from.

    Throughout those experiments, make your kid keep a notebook, keep your own notebook as well, make him formulate different hypotheses and help him design the experiments that could confirm or disprove his own hypothesis. And the point shouldn't be that he gets all the correct answers, he won't get them, and that's ok. Don't aim for perfection here. Germ theory wasn't fleshed out in one day, don't push your kid to flesh it out in one day either. Just get him to get used to that thinking process of formulating hypotheses and trying to disprove them. And do make sure to keep those notebooks up-to-date, this way every time you get back to your experiments -- you can get back to the last place you just left of.
