The Inconstant Constant

By Roland Piquepaille

I have to admit: this article has nothing to do with this blog's theme.

But (if some australian researchers are right) this is pretty incredible. The value of a constant named alpha (read the story to get a full explanation) might have changed between 2 billion and 9 billion years ago. This specific *constant* has increased by 0.0006%.

Then it stayed constant. Puzzling...

Money Talks -- and so should ATMs

I don't know what is the percentage is in France, but BusinessWeek writes that only one-fifth of blind people in the U.S. can read Braille. Which means problems to get cash.

It seems that ATMs should be audio-enabled in a not too distant future.

Microsoft's mythical man-years

It's no mystery that Microsoft has put lots of people to work on more secure software in the last couple of months. Now, a Microsoft exec is saying that his company already has done many more men-years securing its software that the open-source community ever did.

The author found a book published in 1975: "The Mythical Man-Month," by Frederick P. Brooks, an IBM veteran (I insist, a veteran in 1975). This guy looked at large projects at IBM, which were almost behind schedule. He wrote something which is still true: "Adding manpower to a late software project makes it later."

He also concluded: "The man-month as a unit for measuring the size of a job is a dangerous and deceptive myth."

Famous quotes containing the words inconstant and/or constant:

    The awful shadow of some unseen Power
    Floats though unseen among us, visiting
    This various world with as inconstant wing
    As summer winds that creep from flower to flower;
    Percy Bysshe Shelley (1792–1822)

    There’s nothing constant in the world,
    All ebb and flow, and every shape that’s born
    Bears in its womb the seeds of change.
    Ovid (Publius Ovidius Naso)
