    Remind Me: Damage done in San Francisco in six days 

    I am lucky enough to have a sister living out in San Francisco, and to be able to work out of our offices there. Below is a hit list of the places I ate at and visited in the span of six days. My stomach has finally recovered.

    Wineries (Sonoma County):

    Both of us are lucky enough to have been through Napa several times, so we decided to venture into Sonoma County. The last item in that list is an unsuspecting general store off of Dry Creek Road in Heldsburg which has an incredible sandwich list. This area turns Napa on its head, with a much more family-run low-key atmosphere. There is none of the pretense of visiting a large production winery such as Mondavi or the herds of people who visit Duckhorn.

    To Eat:

    I cannot recommend every one of these places enough. Izakaya Sozai serves killer ramen. Yank Sing serves dim sum on weekend mornings that melt in your mouth. Shuck your own oysters at Hog Island (we learned in about 30 seconds) at the farm while sitting on benches along Tomales Bay. Mission Chinese blasts gangster rap while you gorge yourself on craveable Chinese food.

    Go, eat, recover later.

    The Internet is slow. Is the Internet down? 

    We have all heard the same questions at one point in our careers, “Is the Internet down?” or “Getting to X site is slow.” You scramble to a browser to see if Google, ESPN or the NY Times websites are up. Then you fire up traceroute. In some cases, the pages might load slowly, in other cases not at all. These two situations are often downstream fallout of two connectivity issues: latency and packet loss. Latency is the time it takes for a packet to get from source to destination. The speed of light says the latency for one packet to get across the USA from New York to San Francisco is normally between 70-90ms [1]. Packet loss occurs when packets do not make it from their source to destination, being lost along the way. Many factors can contribute to packet loss, including overloaded routers and switches, service interruptions, and human error.

    When diagnosing network issues between source and destination, it is helpful to have data to backup your suspicions of slow and inconsistent network performance. Insert Smokeping.
