  • Bluesky's open API means anyone can scrape your data for AI training
  • That is kind of how the open Internet works. AI or no AI, the rules have been the same for years.

    If you put anything online, it is no longer under your control and fancy APIs just remove a step or two in collecting that data.

    If you can get people to believe in magic they have never seen because of stories that never happened to explain an afterlife that nobody knows about, you can easily get them to also fork over a considerable amount of their income to avoid a fate that will never happen.

    Nevermind that you can also produce some fearless soldiers who will gladly hand over their life for no real reason.

    Eesh. Humans are weird.

  • In principle, could gravity be used to send a information from within a black hole's event horizon?
  • My guess is that you are visualizing the event horizon as a gradient when it should be viewed as a hard-line barrier.

    As anything approaches the event horizon, it still has a chance to escape. Once an object crosses that line, it's game over: All arrows point in.

    Now, I have also heard that of you wait long enough for the black hole to completely evaporate and are able to collect every bit of the black hole as it does, you should be able to reassemble the data you desire. It would probably take a supercomputer more massive than the original black hole, but it's worth a shot. As a bonus, I believe you have to solve for an information duplication paradox that is tucked in there somewhere as well.

  • It's great for what it is. For me, it's intended as my portable synth and it fills that role quite well. While the minifreak is great, it's is coupled too tightly with its software for it to leave my desk. The microfreak is more standalone and only functions as a more traditional synth, which is perfect for me.

    It's not an absolutely stellar device, but I don't need it to be. It's a good mix of analog and digital functionality, which is also my preference.

    TBH, it's just a way for me to offload a couple more oscillators from my PC/DAW. Some of my more recent music is extremely synth-heavy so the fewer instances of software synths I have running, the better.

  • This reeks of a scam. When something is supposed to do everything, it generally will be an expensive way to do nothing at all.

  • Which lessons have you learned since the release of the DLC?
  • My experience is practically a carbon copy of yours, so I'll just tack my reply here.

    I just started using robots a few days ago after numerous game restarts since the DLC was released, so I am still a hair behind. Rocket launchers vs. biter nests are starting to get a hair difficult now, so tanks are on the menu for tomorrow.

    The biggest issue I had was planning around the sheer scale of the base we need to build and how to design and manage busses for them.

    Once I figured out how to plan the layouts for entire stacks of furnaces or assemblers, my base got sooo much more efficient. The exact opposite, but just as satisfying, is when I leaned to quickly automate random odds and ends with temporary assembler puzzles. (Early game red science is a perfect example of that.)

    I guess the biggest lesson is attach a massive multiplier to everything. ie: Will 2 turrets fend off attacks from one direction? Cool, but put 6 turrets there instead instead of the 2 it takes now. 10 absolutely wouldn't hurt either.

  • Is there a way to convert json files to text?
  • JSON should be text already since it is just a data structure and not a binary file format. You should be able to cut-n-paste whatever you want.

  • [FoAR] Foundations of Amateur Radio - Why does your Wi-Fi connection drop out when cooking lunch? #podcast
  • Some scale might help put things in perspective here as well. Your common WiFi router only transmits its signal at around 100 milliwatts, and generally much less. This is good enough for your house and it limits range and interference with other systems quite well.

    The average microwave operates at about 1000 watts or so.

    So, take 10,000 wifi routers stick them all in a small metal box, focus all their transmissions to one spot and now you can cook food! Neat, hu? (This is ignoring some other key aspects of how it would actually work, but you get the point.)

    Shielding (faraday cages) are extremely effective at shunting energy away, but there still can be issues. The first thing that comes to mind is a subtle mechanical issue with a door on a microwave that may allow it to open slightly before the magnetron is fully discharged. You have now swamped a fairly quiet RF environment with a thousand watts of power for a brief second.

    That quick burst of energy is going to get picked up by the hundreds, if not thousands, of finely tuned wifi antennas you are probably around right now. The results of that, thankfully, is minimal because of good circuit design. It can still cause chaos with some hardware though.

  • Crossover episode
  • And the capability to create as many copies of that ring as you want, actually.

    Just one copy of "the one ring" would cause chaos. Now, imagine a hundred million of those fuckers on the open market! While some of the immediate side effects might be a bit weird, but it seems like the entire system of control might collapse fairly quick.

    Leak a copy of the transport buffer to China, while we are at it, and we should be seeing those show up on EBay for $1.99 in about a week or so.

    It's no so precious any more, is it??

    Completely wiping macOS with installed MDMs?

    I have two MacBooks that I acquired through two different startups. Both companies no longer exist and I was basically given the laptops. (They have just been sitting in my closet for a few years collecting dust, and it seems like a waste.)

    Unfortunately, now that I want to use the laptops as part of a local k8s cluster (or even dedicated music production hardware), I am locked out of wiping the things because they want to connect to MDM servers that no longer exist or have admin passwords that have long since been forgotten.

    Since these laptops are essentially "bricked" I have no problems opening them up and attempting hardware hacks to get around this stuff.

    Both laptops are in various states of reset or wipe due to previous attempts to reset. (Funny thing, actually. I was personally responsible for locking down one of these laptops at the time they were in corporate use...)

    Trash or treasure? I dunno. I am apple-dumb.

    Firmware extraction from PIC16F using MPLAB X and Pickit3; BIN is all zeros

    I have been attempting to extract the firmware from an HVAC controller board using my Pickit3 and MPLAB X.

    It seems that many HVAC controllers are PIC based and most are kind enough to include debug/flash pins. Grabbing the firmware images should be trivial once the correct pins are traced out. MPLAB X will see my Pickit3 and the target MCU, but it fails to pull an image that isn't all zeros. (The "bin" file is a text file with each line noting the start address, followed by 16 byte values.)

    I do get an occasional "Target device ID invalid message" but that is usually due to my janky wiring to the board. Once I get that issue cleared, MPLAB will always warn that the debug bit (byte?) is set on the MCU. (That doesn't make sense as the MCU should be running standalone on the board during normal operation.)

    Is there some kind of read protection that may be enabled on the PIC? Do I just need to unsolder the PIC and put it in its own dedicated circuit for pulling the firmware?

    I am composing everything in mono now.

    The one trick that Big Music doesn't want you to know!

    I was absolutely struggling when I went to do a final mix after writing everything in stereo. For me, it was a whack-a-mole game: Fixing one problem created ten more, bass was unmanageable, highs tended to blare or everything was a midrange soup and I constantly struggled with frequency cancellation.

    Above all other problems, music was not portable. It would sound great with headphones, but became a blown out mess on external speakers.

    Mono. Just write everything in mono. If the track sounds good in mono, even just the slightest bit of stereo separation makes it sound awesome!

    As a perk, it forced me to learn more about compression and limiting and when it is applicable. If something is inaudible in mono, it's going to sound like absolute garbage in stereo. (It also forced me into EQ'ing nearly every component of a song at first. I am not nearly as aggressive with that now, but again, it opened up new doors that I didn't realize existed.)

    Why, oh why, is this technique not pushed more to hobbyists and beginners? Is there a shortcoming that I am not aware of?

    Obviously, this isn't a cure-all and I kinda framed this post as a magic trick. Its one hell of a teaching tool, if nothing else.

    Resin printing. A call for information. (White papers, documented research or testing data)

    I am fed up with resin slicers.

    Chitubox is about as stable as a drunk on a tightrope, Lychee is bad for engineering models and over-priced if you just want some basic support functions and PrusaSlicer is under-developed. All of these solutions work for different things based on the goals of the user. (For some, Lychee is an excellent value so my distaste is likely not universal.)

    What really pissed me off is that support painting shouldn't be a paid feature. You hold the mouse button down and drop a support at specific distance from the last. It doesn't take massive cloud computational clusters or huge storage requirements but yet, money. Fuck. That.

    I want a completely FOSS tool that is stable and includes functionality for auto-positioning models and has a full set of knobs and levers for support generation, support painting included.

    So, I spent the morning getting a dev environment setup for PrusaSlicer to use as a base for resin-only tools. Over the next month or so, I'll take some time to strip out all the FDM support and get the slicer into a bare-bones state with only the existing resin features. Of course, it'll be on GitHub.

    Back to the main subject. I was hoping that y'all had references in regards to anything resin printing: Support placement methods, model rotation optimization, resin strength data, FEP peel force data or anything that could be coded and implemented into a slicer. Hell, even discovering different methods for hollowing an STL would be nice.

    Data and strategies for various tools would be nice to have at this point to at least start forming a roadmap for development. (One of the first goals is to integrate UVTools as a snap-in, somehow.)

    FDM tools are plentiful because of wide spread adoption. Resin printers still seem niche so printer manufacturers naturally gravitate to writing their own tools for their own hardware in their race to the bottom.

    With all of that said, I am actually curious if others would even want to see a project like this kicked off.

    Which DAW, if any, and why?

    I have been using FL Studio for years. It was easy to pirate when I was younger and broke, and it's still flexible enough for anything I want to do now without hassle. (The license these days is "meh" for clips and plugins. However, I am designing and beginning to record most of my own instruments now with a core set of plugins.)

    I would like to experiment with an open source DAW, but not sure which routes to take there.

    Show spinner when uploading images for post.

    Spinner shows while thumbnail is being shown after upload and thumbnail is being generated, but not when actually uploading. (I am attempting to attach gif to this post, but not sure if upload has failed, still going or just not possible.)

    I am mobile while I am creating this post, so uploads are laggy anyway.

    Optional input field for manually typing in community names

    Search is fine, but there have been several cases where I have wanted to manually enter a community name and instance.

    Search can be odd at times and being able to have connect at least attempt to jump to a community would be a nice to have.

    Invalid search results. (images in comments)

    Edit: I can now post and view cat pics. Yay!

    Searching for "cat" or "cats" yields cat@lemmy.world with Connect, but not from web. "cat" is an invalid community.

    cats@lemmy.world should be correct community and listed in search results.

    I can't remember the last time I spent a couple of anxiety filled days in bed because of doing something extremely stupid.

    I mean, I still do some stupid and brainless things but I can own that stuff without fear.

    The absolute worst is only being able to half-remember most of the stupid shit I did. That stuff still kinda haunts me, but in some ways, that is a necessary evil of sobriety.

    This was just a random thought that I needed to write. Maybe it gives someone else something to hope for. Maybe it reminds others of why we choose not to drink. Regardless: IWNDWYT

    Mac 'n Trees

    A few hours later, I just discovered how long this cheesy noodle trend has been going on for.

    Also, this idea was already taken by a previous poster who likely started this trend quite a few days ago, I see.

    Would celite/carbon vacuum filtration perform well enough to remove photopolymers from isopropyl alcohol?

    I am simply on a quest to find an effective non-distillation method for purifying isopropyl alcohol used for rinsing resin 3D prints.

    I have seen some elaborate systems for curing and then filtering resin that is suspended in the isopropyl by running it through standard carbon water filters. That just seems a bit over-complex and does a poor job of removing dyes. In some cases, the filters are not fine enough and the isopropyl will eventually get "sticky".

    It seems to me that a finer filtration system would work much better. Carbon and celite should catch most of the monomers and oligomers, but I am not sure about the photoinitiators and other additives.

    Distillation is obviously the best method for purity, but there may be a worse cleanup and a higher fire hazard risk.

    Are there better materials that I could use for filtering besides celite and carbon? IPA is tiny compared to the rest of the molecules I am dealing with so filtration seems viable.

    (I should note that I would bulk develop the used IPA in clear plastic containers in the sun for a day or two first.)

    Fork an open source version of Connect (suggestions and discussion welcomed)

    Before I get into my comments, I just want to ask that if you haven't bought the dev a coffee, please buy him a coffee. Personally, I have bought several with the intent of covering for those who cannot. Our dev has earned it.

    I am just going to say that Connect is awesome. Even through early development, when there were huge issues, it progressed at a good pace. And yeah, it has gotten super stable and functions great as a simple and easy to use Lemmy client.

    I would also like to make clear that I respect this app as the sole devs creation. He/She is 100% able to direct this project as they see fit. Period.

    However. One person development teams can be a serious risk to the longevity and stability of an app. People get tired and burned out. People have actual lives outside of working on a single app. People can just vanish from dev work. That is all normal.

    With the recent Lemmy instance updates and some subtle bugs that are showing, my concern is that it may become a much larger challenge to keep this app up to date. In my limited dev experience, core API changes (or API bugs) are a royal pain in the ass to deal with. A person could spend more time just keeping their app functional instead of developing new features or working on minor bugs.

    I was hoping that people in this community that have experience with the development of large open source projects, can contribute ideas for our dev that may make it palatable to open this project up to additional contributors.

    I think the biggest things I would like to call out is that if this project is opened, it may damage any revenue that is being generated by this app for the dev and I don't want to see that happen. (People gotta work and people gotta eat. )

    What open source licenses are available that would keep full control of this app in the hands of the original dev? (Is that even a viable option?)

    Quite simply, other than opening this app up fully, I don't quite know exactly what I am asking for. It would be nice to keep full control of this app in the hands of the dev, while also allowing community development.

    Just to reiterate, this post is not meant to be rude or pushy. If anything I said came off that way, it was absolutely not the intent and offer a humble apology if it did.
