  • We can reliably screen for HIV (all blood donations are) why the fuck are homosexuals discriminated against over this.

    except that the tests are (per cdc) up to 90 days late in detection. So you may get infected and spend 3 months testing negative.

    And judging by OPs being german, where the rule (admittedly only since 2021) is “you may only have fucked one guy for the last 4 months”, this seems like being on the safe side, but not completely excessive to me.


  • I’ve donated plenty of times, because it makes sense that there is no other way to save lives than to donate.

    On the other hand, I’ve been wondering for years, that while I’ve been told a million times that “blood reserves are low - donate blood now!”, I’ve not ever heard that a single person died due to lack of available blood.
    Why would something like that not be reported if you want to motivate people to donate?

    My personal guess is that this comes because “lack of avaiable blood donations” isn’t a valid cause of death, the cause of death is whatever else (gun shot wound, knife severed artery / complication during surgery etc), thus it’s hard to pinpoint. Also Doctors may try to “save” blood, when they know little is available, and people may die that may have lived if they had gotten (more) blood, but also they may not have and it is hard to tell.

















  • There are also still a lot of QoL issues with the GUI and no real attempt to bring in influences and widgets from direct modeling. FreeCAD is pure of heart and pure of thought, but I’m not sure I’m quite there, though I can at least imagine it now

    fyi, there is now ondsel
    based on FreeCAD, their release introduction reads:

    So our thinking was: we should focus on a polished user experience and features that are essential to professional use. Let’s build something we feel good about recommending it to someone working on a deadline. And let’s build a service for vaulting and collaboration.

    Our primary objective is to provide polish and sorely missing features — that’s a large part of the added value. We’ve made big and small changes in the upstream project, but the four vital projects for us have been toponaming, integrated assembly workbench, UX/UI, and collaboration.

    full Article / release notes

    So working exactly on what most consider FreeCADs weaknesses I’d say

    Unfortunately toponaming is still not done for either. That will be a huge leap in usefulness for me.
    (fixes models breaking when their topology changes)


  • Infill has massively diminishing returns. I don’t think 100% is required. Usually it’s much better to increase the number outer layers.
    That said, depending on the cost scaling, the possibly positive effects of extra mass, and how much I want to avoid a second attempt, massive objects can make some sense.

    PLA becomes brittle with moisture (from your hands and/or air). I would recomment PETG / ASA / ABS (ascending order).

    Yes, basically all CAD and slicers (3d-printer software) can mirror. PrusaSlicer for example can mirror and then save to stl again.
