  • Weight Loss

    I started the Keto diet in February and lost 33lb in ten weeks. My starting weight was 213lb with 19.5% body fat. My weight at the end of the ten weeks was 180lb with 13% body fat.

    In the four weeks since, I’ve re-introduced carbs, am still eating at a slight caloric deficit, and followed this exercise program. I now weigh 185lb with 10% body fat.

  • Too Much Whey Protein Makes Me Depressed

    For me, consuming large amounts (>1g/lb) of whey protein is correlated with depression.

    I have experienced this three times in 15 years. I recognized it during the first and most recent times, and in the middle case only upon reflection during the recent bout. My mood drags down, becoming depressed after about two weeks. After I stop consuming whey protein, my mood returns to normal within a few days. Consuming the same amount of protein from meats and soy does not seem to make me depressed.

    I’ve found a few instances of other people reporting the same. Also, it’s worth noting that supplementing protein helps some people with depression. In my case, I think my body has a hard time digesting/processing the whey, which changes my body’s chemical balance, causing the depression.

  • I sold my motorcycle today. My friend Pavel and I both bought BMW motorcycles the same day in 1998 after Microsoft acquired LinkExchange. The motorcycle was iconic for that stage of my life. I loved living in San Francisco, going out with Kristy on the bike, and feeling her embrace as a passenger with her arms around my waist. Once, Pavel and I took a long lunch to watch the Blue Angels practicing over the bay, he on his bike, me on mine. We were riding along near Crissy Field when a Ferrari passed us, pointed to Pavel’s bike - not mine! - and gave him a thumbs up. It’s hard to believe it’s been almost twenty years.

  • Encoding Binary Numbers In Integers With Primes; Decoding Binary Numbers From Integers With Factoring

    Scott Aaronson’s Quantum Computing Since Democritus has this excerpt:

    When I was in junior high school, I had a friend who was really good at math, but maybe not so good at programming. He wanted to write a program using arrays, but he didn't know what an array was. So what did he do? He associated each element of the array with a unique prime number, then he multiplied them all together; then, whenever he wanted to read something out of the array, he factored the product.

    Here’s how this works:

    Start with a binary number. This only works with binary numbers.

    Here, we’ll use 1010.


    Match up each digit in the binary number with a prime.

    Here, we’ll match the binary digits starting from right-to-left, resulting in:

    Prime Binary Digit
    2 0
    3 1
    5 0
    7 1

    Multiply the prime and its binary digit.

    Here, we get:

    Prime Binary Digit Product
    2 0 0
    3 1 3
    5 0 0
    7 1 7

    Multiple the non-zero products together.


    3 * 7 = 21

    The binary digits 1010 are encoded in the number 21.


    Factor the integer.

    Here, the factors of 21 are:


    Using the same mapping table from above, note which primes are factors of the integer.

    Here, the primes are in bold:

    Prime Binary Digit
    2 0
    3 1
    5 0
    7 1

    Starting with the first row, if prime was found in the factors, it represents a one in right-most digit of the binary number. Else it’s a zero. The first row is the right most digit, the second row is the second from right and so on.

    Here, the primes are absent for the right most, present for the second-from right, absent from the third-from-right, and present from the forth-from-right, resulting in 1010.

  • Quantum Computing: Storing Information In Particles

    Quantum computers store data in qubits, short for quantum bits.

    A qubit can be made with a single atom. Electrons in atoms have poles, like the magnetic North and South Poles. An electron’s poles can be oriented in one of two directions - either “spin up” or “spin down”. An electron’s polarity is determined by its energy state. Changing the energy state can flip the orientation.

    The up-or-down orientation of the polarity of an electron is used to indicate zero or one. Thus, qubits can store information.

    At room temperature, the energy in the environment cause the spin to bounce randomly back and forth between the up and down states. So qubits are cooled to almost absolute zero to keep them in the spin-down, their lowest energy state, until they are set by adding precisely tuned microwave energy.

    When observed, a qubit’s electon’s orientation will either be spin-up or spin-down. Prior to observation, a quibit has a certain probability (percent liklihood) of being zero or one - this is a bit like Schrödinger’s cat. These probabilities (that add up to one) are refered to as the particle’s “super position”.
