  1. Motivation on Human Powered Helicopter · · Score: 1

    It's amazing that they get such a big team together (there is a list of the members on the website) and all are working motivated towards this goal... sadly, this is very rare.

    I only know very few people who have an interested in building things, educated tinkering etc. And as a physics student, I have many contacts to people who should(*) be interested in such things.

    (*) - IMHO, at least some of them should...

  6. Re:Sadly, yes... on Does Your Employer Own Your Thoughts? · · Score: 5, Insightful

    I wonder if all these documents and provisions of the companies are overall economically efficient....

    For the particular company, it's a plus to extort it's employees in such a way. But now, with such a known case of lawful "mind-owning", maybe some people will be more careful about what ideas they'll give to their employer... thus hampering the free flow of ideas which mainly drives the economy.

    The same happens IMHO with quick hiring and firing of people. Noone thinks that it is wortwhile to work more than is neccessary for not getting fired. And noone gives more of his/her ideas than what is neccessary to keep the job.

    Maybe someone with knowledge of both economy and social sciences can defeat or confirm this argument?

  8. Re:Talk about real life experiments... on Memory Card Torture Tests · · Score: 4, Informative
    ACK, and as the parent poster says, it's flash, not RAM. Non volatile flash memory consists of this:
    |electrode 1|
    \-----------/

    [ Insulator ]

    ==Floating ==
    ==== gate ===

    [ Insulator ]

    /-----------\
    |electrode 2|
    It's the floating gate that may hold a charge which is interpreted as a single "1" (or 0, depends how you define it) bit of the flash.
    So... as you can see, with a strong enough electric field, you may surely be able to move the charge across the barriers (e.g. break-through of the insulation or maybe tunneling of the electrons when you skew the potentials alot).

    Now the magnetic thing:
    Because the electrons in the floating gate move (they must do that in every case because of quantum uncertainty, but the greater effect here is the temperature movement!), they have a speed and as you may know, moving electric charges in magnetic fields feel the lorentz force... BUT this force does not change the energy of the particles, i.e. they do not get faster when one applies a magnetic field. So, yes, maybe there're weird changes in the bandgap. I don't know. Try it out, would be a nice experiment.

    Post a link to a graph here that shows the total number bit errors over magnetic field strength :)

    Static RAM mainly consists of two MOS inverter structures wired together on the chip to form a flip-flop. Static RAM needs a small bit of current (because of inevitable leakage currents) to keep it's state.

    At least, that's how I read it some time ago for a seminar in the semiconductor book from the creator of these devices (S.M. Sze).

  10. Re:Old Horror Stories on Abused, But Working Hardware Stories? · · Score: 1

    Oh, the good old commodore times.
    In the time when everyone disposed his/her C-64 (early-mid 90s), I managed to use the C-64 as the control computer for some electronics project.
    Because that was the time where the C-64 was really cheap (everyone gave it away), I soldered stuff directly onto the expansion-/user-port.

    Now, the project didn't really work but I wanted to recover the C-64. I took a jigsaw and cut right through the mainboard.

    The computer still works, but has no expansion/user port.

    I would never do it again, they're too valuable (both in the nostalgic and the economic sense) now.

    There is a reason for this, it's called comparative efficiency and it's why trade between individuals exists in the first place.
    True to a certain degree. But you have to take into account that there once was a similar situation between individuals. Which led to the formation of unions. Now, there are also competing individuals but far 'better' controlled because not easily able to unionize.
    And there are various types of market failure which the rabid pro-outsourcers overlook. Things like infrastructure etc. are taken as free natural resources like air by outsourcing companies.

    Well, CW *and* voice.
    I know a ham (I also have a ham license, but not the neccessary money for the equipment) who demonstrated this a few years ago and it was just amazing!

    He has a lot of equipment and some agreements with the goverment for increased output power.
    So he was able to do a few kW (5?)@2.5GHz on a 9m fully steerable dish and voice/SSB modulation if I recall correctly.
    Now, the first beautiful thing was seeing the lights fade in sync with the voice because of the high power requirements of the transmitter :)

  19. Re:I was thinking of ditching XP... on Gnome 2.6 Usability Review · · Score: 1

    If you are familiar with usability tenets you'll know that giving users too many choices is the same as giving them none at all. Every option you give a user is a choice he has to make. Sometimes he doesn't want to make a choice, he just wants to get stuff done.
    I disagree. Make everything configurable but provide sensible defaults. Display the more important options first. Make a button which opens an extended dialog for the more intricate options.

    I use a mixed gnome/KDE environment (Gnome as my main desktop, and KMail and other stuff from KDE) and despite of mainly using Gnome, I think KDE got it right. Look at the print dialog. Not many options, but there is the small button in the lower left corner...

    Yes, maybe I'm in a very small minority but I sometimes use obscure options/features in programs. Over time, I get accustomed to them.

    Trying to keep features leads to bloatware? IMHO, bloatware is more the result of too tight coupling of the various modules behind the scenes. If features get removed and are instead available as plug-ins, everyone is happy and the main application remains small and stable.

  20. Re:Project GoneME on Gnome 2.6 Usability Review · · Score: 2, Insightful

    Hi!
    GOOD idea! Really. I'm using gnome right now, but the "remove-every-option-which-maybe-hard-to-understan d-for-some-people"
    attitude which some of the more influental gnome people start to have really pushes me back to KDE.
    Of course, this is only my opinion. But apparently I'm not the only one here...

    But I think you're doing one thing wrong. Instead
    of changing button orders permanently by a patch, better make such things configurable! That is the
    thing I'm missing most in the newer versions of gnome, removed flexibility because "it is better for you". Make an option for the button order. Give the user the power back to change window managers. Etc.pp.

    Maybe this is the least common denominator for all gnome forks? Other options/other configurations?
    That'd be nice because you could cooperate with
    the other forks around and, for features you agree with each other, have a productivity boost :)

    PS. And mods. The above poster does an advertisement. For a free software project. But that is clear and not hidden. He doesn't bash gnome, he doesn't bash KDE, nor does he belong to the GNAA.
    IMHO, the parent is in _no_ way "flamebait"!

    Ahh the common misconception about NAT.
    NAT is not meant as a security tool. It is there to extend your address space (virtually). You probably knew that already.
    One of the _side-effects_ of NAT (often unwanted) is that no connections from outside to your computers are possible.

    But you don't need NAT to do that. A decent firewall (i.e. one you could build/buy which uses BSD/linux netfilter) should be able to do that as well.

    Use the right tool for the job. A firewall. Put an end to the ugly fragmentation of the internet.
