  • Yes, I know, trolls etc. But such action turns any conversation into a bad joke. And anybody who trusts a moderator is a fool.

    Not just trolls - there’s much worse content out there, some of which can get you sent to jail in most (all?) jurisdictions.

    And even ignoring that, many users like their communities to remain focused on a given topic. Moderation allows this to happen without requiring a vetting process prior to posting. Maybe you don’t want that, but most users do.

    Find a better way.

    Here’s an option: you can code a fork or client that automatically parses the modlog, finds comments and posts that have been removed, and makes them visible in your feed. You could even implement the ability to reply by hosting replies on a different instance or community.

    For you and anyone who uses your fork, it’ll be as though they were never removed.

    Do you have issues with the above approach?


  • As a user, you can:

    • Review instance and community rules prior to participating
    • Review the moderator logs to confirm that moderation activities have been in line with the rules
    • If you notice a discrepancy, e.g., over-moderation, you can hold the mods accountable and draw attention to it or simply choose not to engage in that instance or community
    • Host your own instance
    • Create communities in an existing instance or your own instance

    If you host your own instance and communities within that instance, then at that point, you have full control, right? Other instances can de-federate from yours.


  • I recommend a used 3090, as that has 24 GB of VRAM and generally can be found for $800ish or less (at least when I last checked, in February). It’s much cheaper than a 4090 and while admittedly more expensive than the inexpensive 24GB Nvidia Tesla card (the P40?) it also has much better performance and CUDA support.

    I have dual 3090s so my performance won’t translate directly to what a single GPU would get, but it’s pretty easy to find stats on 3090 performance.






  • To be clear, I’m measuring the relative humidity of the air in the drybox at room temp (72 degrees Fahrenheit / 22 degrees Celsius), not of the filament directly. You can use a hygrometer to do this. I mostly use the hygrometer that comes bundled with my dryboxes (I use the PolyDryer and have several extra PolyDryer Boxes, but there are much cheaper options available) but you can buy a hygrometer for a few bucks or get a bluetooth / wifi / connected one for $15-$20 or so.

    If you put filament into a sealed box, it’ll generally - depending on the material - end up in equilibrium with the air. So the measurement you get right away will just show the humidity of the room, but if the filament and desiccant are both dry, it’ll drop; if the desiccant is dry and the filament is wet, it’ll still drop, but not as low.

    Note also that what counts as “wet” varies by material. For example, from what I’ve read, PLA can absorb up to 1% or so of its mass as moisture, PETG up to 0.2%, Nylon up to 7-8%… silica gel desiccant beads up to 40%. So when I say they’ll be in equilibrium, I’m referring to the percentage of what that material is capable of absorbing. It isn’t a linear relationship as far as I know, but if it were, that would mean that: if the humidity of the air is 10% and the max moisture the material could retain is 1%, then the material is currently retaining 0.1% moisture by mass. If my room’s humidity is kept at 40%, it’ll absorb moisture until it’s at 0.4% moisture by mass.

    That said, this doesn’t measure it perfectly, since while most filament materials absorb moisture from the air when the humidity is higher, they don’t release it as easily. Heating it both allows the air to hold more moisture and allows the filament (and desiccant) to release more moisture.



  • What have you done to clean the bed? From the link to the textured sheet, you should be cleaning it between every print - after it cools - with 90% IPA, and if you still have adhesion issues, you should clean it with warm water and a couple drops of dish soap.

    Has the TPU been dried? I don’t normally print with TPU but my understanding is that it needs to be lower humidity than PLA; I use dryboxes for PLA and target a humidity of 15% or lower and don’t use them if they raise above 20%. The recommendation I saw for TPU was to dry it for 7 hours at 70 degrees Celsius, to target 10% humidity (or at least under 20%) and to print directly from a drybox. Note that compared to other filaments, TPU can’t recover as well from having absorbed moisture - if the filament has gotten too wet, it’ll become too brittle if you dry it out as much as is needed. At that point you would need to start with a fresh roll, which would ideally go into a dryer and then drybox immediately.

    You should be able to set different settings for the initial layer to avoid stringing, i.e., slower speeds and longer retraction distance. It’s a bit more complicated but you can also configure the speed for a specific range of layers to be slower - i.e., setting it to slow down again once you get to the top of the print. For an example of that, see https://forum.prusa3d.com/forum/prusaslicer/bed-flinger-slower-y-movement-as-function-of-z/

    What’s the max speed you’re printing at? My understanding is that everything other than travel should all be the same speed at a given layer, and no higher than 25 mm/s. And with a bed slinger I wouldn’t recommend a much higher travel, either.

    In addition to a brim, have you tried adding supports?


  • stuck with the GPL forever

    If you accept a patch and don’t have the ability to relicense it, you can remove it and re-license the new codebase. You can even re-implement changes made by the patch in many cases, whether those changes are bug fixes or new features.

    If you re-implement the change, you do need to ensure this is done in a way that doesn’t cause it to become a derivative work, but it’s much easier if you have copyright to 99% of a work already and only need to re-implement 1% or so. If you’ve received substantial community contributions and the community is opposed to relicensing, it will be much harder to do so.

    A clean room implementation - where the person rewriting the code doesn’t look at the original code, and is only given a description of the functionality - which can include a detailed description of the algorithm - is the most defensible way to perform such a rewrite and relicense, but it’s not the only option.

    You should generally consult an attorney when relicensing and shouldn’t just do it casually. But a single patch certainly doesn’t mean you’re locked in forever.






  • If they do the form correctly, then it’s just an extra step for you to confirm. One flow I’ve seen that would accomplish this is:

    1. You enter your address into a form that can be auto-filled
    2. You submit the address
    3. If the address validates, the site saves the form and shows you the address in a more readable format. You can click Edit to make changes.
    4. If the address doesn’t validate, the site displays a modal asking you to confirm the address. If another address they were able to look up looks similar, it suggests you use that instead. It’s one click to continue editing, to use the suggested address, or to use what you originally entered.

    That said, if you’re regularly seeing the wrong address pop up it may be worth submitting a request to get your address added to the database they use. That process will differ depending on your location and the address verification service(s) used by the sites that are causing issues. If you’re in the US, a first step is to confirm that the USPS database has your address listed correctly, as their database is used by some downstream address verification services like “Melissa.” I believe that requires a visit to your local post office, but you may be able to fix it by calling your region’s USPS Address Management System office.




  • Good point!

    If OP is hourly, those 3 hours should be billed as work - probably under a generic HR-related category if one is available.

    If OP is salaried exempt, then this would fall under “doing any work at all” (all that’s needed to be paid for the day) and if sick time is tracked by day and not by hour, then OP doesn’t need to use one. If it’s tracked hourly then OP should make sure to only use 5 sick hours (or less, depending on how long the work-related conversations took) and depending on employer policies may not need to use any sick time at all.

    This also cut into the time OP could have been using to rest. It would be very reasonable for OP to need an extra day to recover, as a result.
