  • The actual difference between a working new mouse and a failing double click mouse is in the button itself (mechanical parts are almost always the problem).

    However, it is not some exotic failure mode. All mechanical switches have a “bounce”, where the contact makes and breaks a few times before settling into the connected position. Switches are typically designed to make the actual contact spring loaded (which is the origin of the click sound you here). As they age, this mechanism degrades, making the bouncing problem worse.

    However, this is a well understood problem that any electrical engineer should be familiar with. One solution is to install a filter capacitor. Now it takes longer to switch between the on and off state, so the inherent bounce in the switch is smoothed out to the point where you cannot detect it.

    They probably did testing with a new switch, and decided that they didn’t need to include any explicit debounce component, ignoring the fact that the switch would degrade over its lifetime.



  • Delegates have been determined prior to the convention for as long as I can remember. That is the entire point of the primary.

    In this case, the person who won the primary has withdrawn. The presumptive nominee is now the person who voters expected to be his VP pick; so they should have understood that their vote for Biden was a vote for Harris if something happens to Biden.

    Additionally, Biden has endorsed Harris. Most of the delegates are pledge to support Biden. While they are technically free to vote their conscious, the argument of “I should support the person endorsed by the one I was sent here to support” is pretty persuasive. As is the argument of “no one is running against her”

    The issue with Clinton was the presence of super delegates, who were not required to follow any primary election results. An open convention turns all delegates into super delegates.


  • In addition to the raw compute power, the HP laptop comes with a:

    • monitor
    • keyboard/trackpad
    • charger
    • windows 11
    • active cooling system
    • enclosure

    I’ve been looking for a lapdock [0], and the absolute low-end of the market goes for over $200, which is already more expensive than the hp laptop despite spending no money on any actual compute components.

    Granted, this is because lapdocks are a fairly niche product that are almost always either a luxury purchase (individual users) or a rounding error (datacenter users)

    [0] Keyboard/monitor combo in a laptop form factor, but without a built in computer. It is intended to be used as an interface to an external computer (typically a smartphone or rackmounted server).




  • At a $188 price point. An additional 4GB of memory would probably add ~$10 to the cost, which is over a 5% increase. However, that is not the only component they cheaped out on. The linked unit also only has 64GB of storage, which they should probably increase to have a usable system …

    And soon you find that you just reinvented a mid-market device instead of the low-market device you were trying to sell.

    4GB of ram is still plenty to have a functioning computer. It will not be as capable of a more powerful computer, but that comes with the territory of buying the low cost version of a product.
