  • 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.



  • Biden tried to restart the deal back in 2021, and has been trying ever since.

    However, it turns out that the US is not the only party involved in international treaties. We can’t just pick up the ball and go home mid game, then come back in a year with a new coach and expect everyone to continue playing like nothing happened

    The original deal was a difficult achievement on its own. Now, we need to not only repeat that, but also deal with the fact that Iran does not trust us to follow through with our end of the deal. Overcoming that needs good negotiation, and a lot of concessions we did not want to make.

    This is why administrations of both parties have historically upheld deals made by the opposing party that they didn’t like. Unilaterally breaking deals every 4 years because of who wins an election makes the US a non-credible partner in negotiations. You can’t just wave a wand and fix that.



  • 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.

    Blaise Pascal is famous for 2 things:

    1. Pascal’s triangle. This describes how to expand expresions of the form (a+b)^n as well as to compute how many ways there are to pick k objects out of a set of n (ignoring order.

    This triangle is computed by starting with 1 at the tip, then having each element be the some of its 2 parents (except the diagonal edges with only one parent, which remains as 1)

    1. Pascal’s wager. This is a theological argument for a belief in god that goes “if you believe and god doesn’t exist, nothing happens. If you don’t believe and he does exist, you suffer for eternity. The logical choice is therefore to believe”

    The natural conclusion is therefore to believe in all gods. If procelatizing happens in just the right way, and no one realizes people are talking about the same god, you end up with a triangle of polytheists, where the number of gods they believe in is given by Pascal’s triangle.

    Edit: gid -> god







  • Coming around? When was he on the wrong side of this issue?

    His October 10 statement includes:

    Right now, the international community must focus on reducing humanitarian suffering and protecting innocent people on both sides of this conflict. The targeting of civilians is a war crime, no matter who does it. Israel’s blanket denial of food, water, and other necessities to Gaza is a serious violation of international law and will do nothing but harm innocent civilians. The United States has rightly offered solidarity and support to Israel in responding to Hamas’ attack. But we must also insist on restraint from Israeli forces attacking Gaza and work to secure UN humanitarian access. Let us not forget that half of the two million people in Gaza are children. Children and innocent people do not deserve to be punished for the acts of Hamas.

    October 10. 3 days after the initial attack.

    Back in January he tried conditioning aid to Israel and requiring the state department to issue human rights report on their conducts.




  • Not nessasarily, the protocol could be written so that an instance simply tells other federared instances “X of my users upvoted this, and Y downvoted this”.

    The tradeoff being that instance then have less tools to work with to moderate voting. Instead of being able to do global vote ring detection, the most they can do is look for abuse on their own server, and trust that every instance they vote-federate with does the same. Even then, with every instance trying to be vigilant, no one instance would have the info to detect a cross-instance abuse.
