    I see no reason to discuss these things with someone intentionally misunderstanding everything I say.

    My grandfather for example fought in WW2 but I'm pretty sure I could shock or gross him out with stuff that wouldn't really bother most of my peers.

    And do you know why? Because those images may be triggering actual memories of close friends being mutilated by enemy fire, of picking pieces of a close friend's guts and brains off his face and uniform, of the smells of decaying corpses that one can not avoid. You, your friends and myself have a very different set of thoughts and memories and emotions for these images to trigger. Your grandfather is not being grossed out by what he sees in the picture, but rather what he experienced in real life. Add to this that memories created during high stress like combat are some of the most vivid and persistent, its nature's way of making sure we don't forget the lessons of a close encounter with death.

    I knew a WW2 paratrooper. I asked him if parachuting was scary. He said it was terrifying. That at Normandy he was near the end of the line of troopers to go out the door. That their plane was taking enemy fire and they stood there unmoving waiting for the signal to jump. And when the signal was given it seemed like forever for him to get to the door. He said he didn't "relax" until he hit the ground. He said for the Market Garden jump he was scared sh*tless from the moment he put the parachute on until he hit the ground despite the fact that there was no enemy fire this time. Show this guy a picture of someone parachuting and it is not the thought of hanging high above the ground supported by a piece of nylon and some thin cords that it causing him to feel some anxiety, as my original question attempted to query regarding.

  3. Party loyalty makes you irrelevant ... on US Midterm Elections Discussion · · Score: 4, Insightful

    For myself, the next candidate who seems reasonably competent will get my vote, doesn't matter what party.

    Loyally voting for your party makes a person irrelevant. Their party can ignore them because they have their vote, the other party can ignore them because they cannot attain their vote.

    Belonging to a party is fine, just don't let them think they get your vote automatically. If they put up a weak candidate, if the incumbent has a history of misbehaving or acting against the public interest then sorry, maybe next time.

    Politics is darwinian. Votes are the true currency of politics. If votes are spent wisely, and punitively, politicians will adapt accordingly. This is how real reform can be achieved.

Both sides are allocating their time, money, personnel and other resources to achieve the electoral/districts(*) vote. For the popular vote to be a meaningful statistics it would need to be what one side was actually going for. As it is the popular vote is merely highly correlated with the electoral/districts vote so it occasionally goes the other way, just trivia when it happens.

    Losing sides like to bring up irrelevant statistics to console the fans. In politics its sometimes the popular vote. In football it may be how many yards did the team move the ball while they had possession. That's interesting and all, but yardage was not what the team trying for. Just like the popular vote was not what the political party was trying for.

    (*) Note that we are talking about the nationwide results, the results in all districts, not the results in one particular district. Gerrymandering is a problem, it is a local phenomena, and both parties actively engage in it. Gerrymandering is done at the state level, so whatever party controls the state legislature gets to gerrymander to give their party an advantage in federal elections. Thus there is a certain amount of canceling out in the US congress. In no way should this be interpreted to say gerrymandering is not a problem, it is

    SpaceShip Two is not a technological dead end. An alternative design of SpaceShip Two can carry a payload rather than passengers. In this alternative design the SpaceShip Two craft is a "mothership carrier" type of vehicle to launch a more conventional but small rocket from. This small rocket will deliver small satellites and payloads to orbit.

    The basic idea is to utilize multiple stages of "motherships" to deliver the payload. Each mothership optimized for different environments and stages of the flight. More importantly these early stage vehicle are reusable. Unlike say the early stages of a Saturn 5.

    In economics there is a concept called "willingness to pay". Tapping into the higher "willingness to pay" of the wealthy has been used to bootstrap a company or pay for product research, design and development again and again and again.

    Among other things SpaceShip Two is researching:
    - The mothership carrier concept.
    - A hybrid rocket motor design.
    - The feathered re-entry concept.
    - New materials.

    SpaceShip Two is an intermediate step in a journey, not a milestone in that journey itself. Technologically speaking that is, it is perhaps a milestone in terms of paying for that journey.

    There are people who go into a formal CS/CE program because they have a genuine interest in programming. There are also those who go into a formal CS/CE program because someone told them it is a good career path. While the later (career path) can be decent programmers the former (genuine interest) are the ones who tend to truly excel. The later tend to be both formally trained **and** self taught.

    Those with a genuine interest in CS/CE tend to learn a lot on their own. And a university setting **greatly** facilitates this. At the university there is an incredible density of like minded folks to learn from or in partnership with. Online and remote can be useful, but two or three in the same room is often better. Plus professors are actually useful, they are often sick of the "career path" type students as well and often are very supportive and encouraging of those with a genuine interest. Besides the like minded folks the university environment offers access to incredible hardware and software that might otherwise be unaccessible. Whenever I asked for access to some specialized equipment (ex workstations with licensed software normally not available unless you are enrolled in a particular class) the professor in charge would ask why and I was never turned away because my project was a personal one, just curiosity. Even professors in other departments were supportive. In grad school I was considering a CS research project that involved a submersible robotic vehicle. I talked to a mechanical engineering professor about the potential project and he was very generous with his time and supportive.

    One nice thing about supplementing genuine interest and curiosity with formal university training is that the formal training tends to be a well thought out somewhat comprehensive tour of important topics. Left to oneself the self-taught tend to focus on the more interesting or the more obviously relevant. However some boring and seeming no-so-relevant topics turn out to sometimes be surprisingly relevant and useful. At least that has been my experience, some classes I would never have selected on my own surprised me with their eventual value. While it is certainly possible that the self-taught can read and learn such a comprehensive set of topics at a university level this is exceptionally rare, incredibly rare. In 30 years I've worked with a lot of talented self-taught individuals but I've only met a handful who have the motivation to read and learn things at this level and over a broad range of topics purely on their own initiative.

    Your argument fails due to what is perhaps the most common caveat in statistics and economics, "all other things being equal". There are huge factors that make those decades different, post-WW2 factors, deferred labor costs, etc.

    Yes, by deferring employee costs to future decades. For example a company like General Motors in the 50s 60s and early 70s negotiated lower labor hourly rates by offering increased retirement benefits. Basically the CEOs of the 50s 60s and early 70s effectively shifted costs from those decades to, well, "now". This shifted cost was one of the major factors in GM's "recent" near bankruptcy.

    The other factor that you failed to consider is that the US emerged from WW2 with not only the only intact manufacturing base but an expanded and modernized manufacturing base. Plus a population that did not see their savings and often their homes and worldly possessions lost, rather a population that had been earning good wages during the war and had no real place to spend their money so they saved it.

    So in the US we had a population flush with cash, a huge demand for consumer goods, and no competition. It was a business environment where a company could survive the dumbest practices.

    Now add a huge government stimulus as the Marshal plan helped rebuild Europe and Japan. This created a huge demand for heavy industry goods and services.

    This US industrial and manufacturing dominance had a long tail as it took decades for former industrial nations to recover from the war. In other words a lot of the profitability of the 50s 60s and early 70s was part of that long tail of the post war years.
