    where would you start designing the circuit I mentioned above (a simple blinking LED)
    I would think: Ok, I need an LED, and I need a power source, and I need some way to make that power source intermittent to the LED.

    So, A Battery, an LED, and a capacitor (more likely a potentiometer).

    Accent and content. The one that really stands out in my memory is the woman talking loudly about the expensive diamond ring she was wearing that her husband bought her when they were in Aspen. And, apart from the rudeness, how stupid do you have to be to talk loudly about how expensive your jewelry is in a public place far from home. (Or even close to home, but at least there you speak the language and know people who might care enough to stop a thief.)

    It amazes me how LOUDLY some people seem to think they have to talk when their conversational partner is seated three feet away from them.
    This seems to be an American thing. When I was in France a couple of years ago it seemed that everyone spoke quite softly. Whatever restaurant we went into it seemed that the loudest voice was an American. And when it wasn't I'm concerned that it might have been us.

    This system seems open to a Coordinated Denial of Service type attack:

    Have a decent sized group of people print out two ballots with opposing votes. Each of them casts one in the computer and the other in the ballot box. Everything matches up except the totals. There is no way to determine whether this is an error in the voting machine or a deliberate act of sabotage. At that point, the entire election must be hand-counted from the printed ballots. In which case, you might as well just plan on hand-counting in the first place.

    Maybe, Maybe Not. Off the top of the head solution: Require by law that the IP Address authority reserve a block of addresses for encrypted communication. Require by law that any commercial entity that desires to use encrypted communication apply for and register a TCP/IP Address from that block. Require Routers to not forward encrypted traffic if the source IP or destination IP is not in that block of addresses. (Identifying encrypted traffic is left as an excercise for the reader)

  8. Re:1680 on The End of Non-Widescreen Laptops? · · Score: 1

    In OSX when you "maximize" a window, that window does not fill the screen. The window gets big enough to display its contents while being constrained by the screen (The window won't grow outside of the bounds of the screen). It takes a bit to get used to and there are some quirks. (For example, if I "maximize" the window and then zoom the contents I have to "maximize" again to resize the window to make it fit.) However, with a wide screen it does make a lot of difference. If I open up a code window and a reference document, I can "maximize" both of them and put them side by side without having to grab the handle and stretch the windows.

    In addition Macs have expose which allows you to view all of the open windows of one or all applications at the same time and select the one you want to see.

    Both of these, as well as the universal menu, take a bit to get used to as it is a different way of working. However, as screens get bigger and multiple screens get more common it is much less useful to make a window fill ALL of the available space.

    I imagine a system that has (or allows me to define) screen regions that can constrain a window and it them to fill the region.

    My take on the universal menu bar is a little different from any that I've seen. Menu bars, need to go away. A full contextual menu would solve the UI problems associated with both the Universal Bar (It's a long way away on a big screen and makes focus follows mouse not practical) as well as the problem with windowed menu bars (Multiple, repetitve menus can eat up a lot of screen space if you have a lot of windows open) A full menu that is there where you click removes the mouse movement issues as well as the screen real-estate issues. I've used Linux window managers that do this and it is quite nice.

  14. Re:Administrative Cruft on iPhone's Development Limitations Could Hurt It In the Long Run · · Score: 1

    I think my proposal of additional bars is about as simple as it gets to solving the problem for "why does the battery run out so fast". If you can think of a better solution do post it. IMO there's a limit of what you can do. Users that don't understand something as simple as a "power consumption" or "CPU" meter should get a more limited phone or phone mode, or live with the battery running out faster.
    I think the point is that if the user has to ask the question then you have already failed.

    Secondly, a power consumption meter doesn't answer the question, it just moves the question to "why am I consuming so much power?" The only way to get an answer to that question is something like Top.

    For the User of the phone the real question is something like "How do I get a longer battery life?" Apple answers that question by preventing background apps.

    And, anyway, isn't this the way PalmOS devices have always worked, only the visible app is active and it is the applications' job to exit/suspend/resume cleanly?

  15. Re:Wow, it really works on Rubik's Cube Proof Cut To 25 Moves · · Score: 1

    I doubt it. Assuming that we count each quarter turn as a moves and that we can only move the outside slices of the cube, that would require that there be an odd-numbered move pattern that could be undone by an even numbered pattern. If you make a move, that move has to be undone to get back to your starting point. To undo an odd number of moves, should take an odd number of moves (maybe not the same odd number). As an easy visualization: If you have a solved cube and you rotate the right side 3 quarter turns clockwise, you can get back to the starting point with either 1 quarter turn clockwise of 3 quarter turns counter-clockwise.

    However, if we change our assumptions and allow movement of the middle slice then it is trivial to move the right side 1 away the left side 1 away and then undo those 2 moves by moving the middle slice 1 away.

    A home is not an investment and shouldn't be treated as one. If you want to try to make money in real estate buy some income properties and get to work.

    Your home is a purchase, like your car. You pretty much have to have a place to live so you might as well buy one instead of renting. No one buys their day to day car with the expectation that it is going to increase in value. If you think of your home as that thing that you're buying to live in you can start thinking about what you want out of your house instead of thinking about what it is going to be worth 30 years from now. Hopefully, in 20 years, my house will be paid for and suddenly I have a whole bunch of net income that I don't have to throw at the bank every month.

In some situations, privatization of services is the right thing, in others government control is the right thing, and in others not having the service at all is the right thing. As for the Federal Reserve, I think having some entity that forces the government to be somewhat accountable is better than no entity. I also think that fractional reserve banking is much more of a problem than the Federal Reserve.
