    Ordered from most to least volatile.

    At this moment it’s bad to be in stocks: it’s a bad deal to sell the stock to buy something else, because they are relatively cheap. The flip side is that it’s a good deal to accumulate stock because it’s relatively cheap.

    So the employer contribution should go to the index fund. Keep several months of expenses in cash or money market in case you end up unemployed during a crash.





  • Most devices actively ask around for the hidden SSIDs they know about. As in, they send a broadcast in cleartext called a “probe request” containing the list of hidden SSIDs every time they scan for access points.

    Today usually the scans use randomised MAC addressess for privacy, but that doesn’t help if you have any hidden SSIDs stored because of this list. Places like shopping malls are known to use these beacons to track the movements of individual people.

    Before 802.11w (that still works almost always because 802.11w tends to be deactivated for compatibility), there was a trivial way to “unmask” a hidden SSID, you have to wait for someone to talk to the target access point, send a disassociation frame to the victim, and wait for the probe request / response when the victim automatically reconnects.













  • For smartphones I think a significant driver of their ever-increasing sizes is that battery technology is lagging behind power demand. The worst thing of having a small phone these days is that the battery lasts less than a day. Big screens used to be too power hungry to be practical but LEDs are extremely efficient these days.

    My prediction is that we’ll return to the miniaturization craze of the 1990s whenever the next breakthrough in battery technology happens.
