  • While DRM is the bane of everybody there are cases where trust and integrity is important and it’s an intriguing look into how hard it is to manage.

    Nah, when the user wants to ensure trust and integrity in his own system, it works just fine. The problem comes when the user who needs to be able to access the data is simultaneously the adversary who needs to be stopped from accessing the data.

    In other words, it’s one of those situations where the fact that it’s hard to manage is a gigantic clue that it’s wrongheaded to try to do so in the first place.



  • speeding is bad…

    True.

    …and that lowering car speeds is good…

    Also true.

    …so all these changes can be implemented.

    No, see, that doesn’t follow because not “all” changes are good. Only modifying the geometry of the street is good. Changing the number on the speed limit sign should only ever be done in conjunction with that geometry change, and even then it’s just an afterthought.

    It’s really, really, really important not to give the people in control of the budget any excuse to think that they can cost-cut “fix the geometry” down to “install lower speed limit signs” and still have it count as accomplishing something!


  • Look, you’re not wrong from a moral perspective; it’s just that your sentiment isn’t useful either.

    • When roads are designed appropriately, the vast majority of people don’t speed and the ones that do are incorrigible. In this, case, trying to shame the latter group to stop speeding is ineffective.

    • Conversely, when roads are designed inappropriately, the vast majority of people do speed. In this case, successfully shaming a few of them into driving the speed limit only makes the situation worse because having a wide disparity of speeds is even more dangerous than everybody uniformly exceeding the speed limit.

    The bottom line is that, from a traffic engineering perspective, trying to shame people into not speeding simply doesn’t ever improve the situation. Moreover, bringing it up in a discussion of how to fix speeding is actively unhelpful because it’s a distraction that serves to dissuade policymakers from forking out the money for the solutions that do work!


  • Nobody cares about your condescending non-solution that ignores human nature and is therefore worthless.

    Traffic engineers have to design for the reality of how people actually act, not some theoretical Platonic ideal of how they “should” act.

    Edit: that first sentence is harsher in tone than @derpoltergeist@col.social deserved, in retrospect. I’m not going to rewrite it because I still mean what I wrote, but please treat it as being addressed towards people who make that sort of argument in bad faith instead of at Pablo. (Sorry, I guess I’ve still got some leftover cynicism from Reddit.)














  • boolean is a totally different thing in 3d software. It’s where you remove something from another something or combine.

    Nah, it’s exactly the same thing. 3D software is just applying a Boolean function to two sets of points at the same time, instead of one scaler piece of data like reading a setting.

    In other words, Firefox is doing f(a), where f is a unary Boolean function (identity or negation) and a is a single true/false value, while your 3D software is doing f(A, B), where f is a binary Boolean function (union a.k.a. AND, intersection a.k.a. OR, etc.) and A and B are vectors of true/false values representing whether particular points of space are contained within object A or B respectively.

    (Some 3D software might be more sophisticated than that, using mathematical expressions of the object boundaries to get exact answers instead of interpolating between points, but I’m just trying to convey the basic concept here.)


  • Everything you mentioned is simply a subset of “[corporation] takes away our ability to own property” (i.e., trying to usurp our fundamental property right to control our computer). You can also add Apple and John Deere “right to repair” to the list, along with automakers trying to lock capabilities of the machine we already payfor behind paywalled subscriptions. It’s all the same underlying issue.

    Make no mistake: corporations are waging a war on the public’s right to own property, and we’re going to be forcibly returned to serfdom if we don’t start fighting back.
