  2. Re:Nice on T-Mobile Is Giving Customers Stock In the Company (cnn.com) · · Score: 1

    As of right now, the stock is down 1.28% for the day. Normally, a share buy-back causes prices to inch up... I wonder why investors are behaving strangely.

    They are spending the cash like a buy-back, but not reducing the number of outstanding shares. So they may be reducing, if not diluting, existing shareholder value.

  4. You are confusing sidereal and solar days on You Can Look Forward To 8 More Years of Leap Second Problems (cio.com) · · Score: 1

    The reason we adjust for leap seconds is that the speed of the earth's rotation 1) isn't exactly 360 degrees in 86400 SI seconds and 2) changes over time, so it's not even a fixed value close to 360 degrees in 86400 SI seconds.

    The earth rotates approximately 360 degrees in one sidereal day. But since the earth is orbiting around the sun, it needs to rotate approximately 361 degrees per solar day. The leap second is not to account for this difference. The leap second accounts for variation in the mean solar day relative to the average mean solar day when the standard second was established.

  5. Re:I didn't know had names on Symbolic vs. Mnemonic Relational Operators: Is "GT" Greater Than ">"? · · Score: 1

    And even if I had know the names of the symbols, I didn't see a reason that the expressions should be read from left to right. I just put the big end of the symbol near the bigger number and the small end of the symbol near the smaller number.

  6. I didn't know < and > had names on Symbolic vs. Mnemonic Relational Operators: Is "GT" Greater Than ">"? · · Score: 1

    Back in kindergarten or first grade, my class did a worksheet on < and >. Each problem was a pair of numbers with a circle between them. We were to put either < or > in the circle. After we completed the assignment, the teacher had us correct our own papers; she would call out "less than" or "greater than" for each problem. I was baffled. I had no idea what she was talking about. Even though I answered every problem correctly, it hadn't occurred to me that these two symbols had names.

    And why would you want to express 1/3 inch in 64ths? Pick a more natural unit like barleycorns.

    21 1/3 64th, exactly. Now, 1/3 meter in millimeters, please? Most seem to think that the great thing about SI is that it is base ten. I disagree. The only thing special about base ten is that most of us have ten fingers.
