  • Try not to think like this. Over the last 10 years, between reddit in the past, and here now, I’ve had to use these places as my only external form of human social contact because of disability issues. I’ve noticed certain patterns emerge with the seasons. These places are largely dominated by certain regions of the world. When those regions go through seasons where the majority of people are doing things elsewhere, the comment and interaction quality decline noticeably. I’ve learned to not take it personally and I turn to other outlets to spend more of my time. This is when I do most of my gaming and reading. I’ve finished all of the primary Dune series and most of Asimov’s main series from Robots through Galactic and Foundation. Most recently, someone suggested the FOSS game Cataclysm Darker Days Ahead. While the theme is absolutely counterproductive for me, the game’s complexity and particularly the documentation of the source code and mods is absolutely fascinating to me. I’ve been exploring JSON tools when it comes to stuff with AI, and the game is like a guided masters class in functional use and tools that use JSON.

    Many people seem to think I’m an asshole or a “bad person” but most simply can’t understand my needs and interests. I never knew what disability was really like and its challenges prior to the day I got hit by a car. I probably had a stupid attitude and said stupid things that made people feel bad in my exact position now. I can’t blame others for their ignorance when condemning them is condemning myself.

    Personalities and functional thought are far more varied in humans than most of us realize in practice. I’ve explored this a whole lot over the last year with AI where it can simulate other contrasting perspectives in very complex ways while answering some really complex questions with relevant sources to back them up. This kind of personality analysis is a major aspect of what LLM’s are designed to understand. The more I’ve explored this topic, the more I have come to realize the binary approach to anything like a good and bad label for a human is completely inadequate. The cause and effect have no simple connections. Most of a person’s “bad” behavior is likely related to cognitive dissonance. If you look up what that really means, it is due to some level of conflict in a person’s life that they are unable to address or have limited/emerging self awareness. If you are noticing such behavior that could be related to cognitive dissonance, work to address the probable causes of underlying conflict in your life if you’d like to address the issue.

    My personal primary conflict is social isolation. That is what I am here to address. I don’t use corporate social media because I’m an outlier of their marketing and exploitation designs where they are unable to accommodate my needs. The inconsistencies of this place are not healthy for me, and it can have a very real impact on my life, but over time I’ve tried to pick up on the patterns and withdraw when I need to do so. Anything that shakes up or makes me question the underlying stability of a place like this is the most deeply disturbing to me. I’m also aware that there is a substantial misdirection campaign that happens with all major elections now. Anyone posting or commenting on such subjects are highly suspect to me. I look at their account activities and ignore or block them if they do not show a wide spectrum of activity and complexity. One day it will become public knowledge that conservative asshats have no morality whatsoever, never have, and are paying thousands of people to post, comment, and write bots to maintain their criminal activities and control. Their presence is completely disproportionate to the population and interests the government represents. When those subhuman jackasses could no longer enslave people outright, they simply shift their focus to redefine slavery to put everyone in their chains. Anyone commenting some shitty nonsense with an account that has little history or a lot of history with no depth is some unethical criminal being paid to do so, is not worth my time or thought, and is absolutely the reason I was right in the first place. Look up the Plutonic definition of sophism and keep in mind that there are some people with a love for their own sadism. These places online are full of people that can be fucked with and there are many that love to take advantage of those that are here for their real human needs. Do not hesitate to disregard anyone that evokes a negative emotion to a well intended comment.

    I’ve been pushing positivity since the beginning before the first 1.5k joined this server. https://lemmy.world/post/36032

    I would do it, and have the time, but I don’t think you guys meet my requirements to make it manageable. I don’t use proprietary software, and use a whitelist firewall with addresses I know and trust, like this server. While I can spin up a secondary network or even a Windows machine, I do not care to do so at all, and certainly not regularly. However, I’m basically at a computer all the time anyways.

    What’s up with the haters? Me, or something I said?



  • How are finishes so durable and thin?

    My assumption of a lack of post processes is because I come from a background of automotive refinishing and repair, where I’ve owned a shop and painted for many years along with getting into custom art graphics and airbrushing. The only finishes I know of that provide a similar durability are two part urethanes. Those are far too thick by comparison. When cutting into plastics that have been moulded, the finish shows no signs of mechanical layering or bonding like a post process finish in most cases. Often a cleanly broken or cut part shows a similar type of penetrating surface alteration I associate with a polishing operation, where the surface transitions in color and grain structure with in millimeter or few (in cases where the break is clean and does not appear to be influenced by stress alterations like ABS where it whitens under tension).

    How does chromate conversion work with a prep regime and what kind of wet paint can offer similar durability to a 2k urethane when it is impossibly thin? Like I know the limitations of urethane well when it comes to corners and pointy bits where it will thin from surface tension. There is not a chance in hell that the buttons on the side of my phone could be painted with such a finish with an even conformal coating and remain durable for years of constant abrasion. Is there a name for this class and type of finish? Where are they sourced? What is the scale of the industry? Is there a way to access the process and products at a small scale?


  • They told us they were going to invest in EV R&D back in 2014. You know, back before we had that orange anal experience of a Russian puppet wannabe pornstar felon president. We put 6b into GM to compete; they pumped their stocks with it. Such is 3rd world America. Lay off the McCarthy bullshit whining about investing in R&D to mask corruption and ineptitude. This was no fucking surprise. Spinning this bullshit is just trying to justify screwing over average Americans with overpriced undeveloped bloated unaffordable garbage made to pad our useless incompetent oligarchy’s pockets.



  • Slowly trying to learn sh while using mostly bash. Convenience is nice and all, but when I encounter something like OpenWRT or Android, I don’t like the feeling of speaking a foreign language. Maybe if I can get super familiar with sh, then I might explore prettier or more convenient options, but I really want to know how to deal with the most universal shell.


  • Yeah, but depends on a person’s goals. I don’t mind being doxed. The privacy thing I’m really concerned about is manipulation of data related to the host server; apps that are used like data loggers of sensors; tracking dwell time; page views; likes, blocks, etc. I care far less about what I say to others in public. I vehemently claim that owning the data about any individual is theft of autonomy, failure of democracy and government, and a form of slavery if one plays out the total philosophical circumstance and implications. Anyone that holds such data about someone else with the intent to manipulate in any way whatsoever is a criminal. I’ve been a Buyer for a retail chain, collected and analysed tons of customer data. This has nothing to do with how data is collected and used now, but this is used as justification for the present criminal data manipulation industry.

    As a disabled person, I need to connect with humans more, and as much as I can here. I totally respect those of you that have other priorities that limit your conversational topics of interest, and I don’t wish to violate those. This place is just my version of a public square, where I’m trying to make general conversation. -warmly



  • So Flash memory works in blocks called pages. The pages contain a header that ends in a few bytes that says what the rest of the page maps to.

    If the file was encrypted, you’re probably SOL. If it was not encrypted it may be possible to to recover some parts of the files. This is extremely advanced level data recovery. I only know the abstract basic principals and would likely struggle to figure this out and recover my own stuff if I ever needed to do this. I’ve only programmed microcontrollers and flash memory devices.

    A micro SD card contains a small microcontroller and some blocks of flash memory, although the microcontroller is transparent to the user and operating system… unless hacking with needle probes in a lab.

    So here’s the basics. Writing flash involves taking an entire Page of memory and zeroing it first. There is a tiny voltage booster circuit on the card that allows the page to get pulsed up and down in voltage a few times in order to completely zero the entire page without any remaining residuals. Once this is done and the entire page has been zeroed, only then is it possible to write the data into the bytes of the page.

    If you want to change a single byte level value in an address that already contains a value, first the entire page is copied to a blank page in another location, then the old page is pulsed a few times, then each value is transferred back into the old page except that the new value that needed to be changed is now set to the new values.

    This is the proper way to write flash at a basic level. If the power is lost in the middle of this cycle, the worst case scenario is that the new updated value was not written. The page in question should never be “missing” because the header record should always point to either the original or copied page. One of the two should always be present and complete… in a proper setup. Obviously, it might be faster to simply use some RAM to hold the page, erase the old page and rewrite it. I have no idea what size pages are in modern SD cards, but on hobby class microcontrollers I have used the pages were 4096 bytes, IIRC. My understanding is that most SD cards use an 8051 clone micro, so it is probably a similar size.

    So here’s the thing, the bulk of the data is always there. Somewhere deep down inside you likely already knew this. It is why you’re supposed to overwrite an entire drive instead of the “quick” erase in most formatting tools. The quick erase is simply deleting a tiny header file that says what exists where on the drive. Similarly, some part of your SD card there is a page or few where the header has been screwed up. Your OS is looking at this header info and seeing a mismatch of garbled junk and saying f-that bs.

    Generally, recovery would involve dumping the raw contents of the flash memory as hexadecimal, being super familiar with what you’re looking at and knowing how to find the page that is causing the error. Generally I assume you’d need to replace the bad page with a good header and it would then work. There are services for this kind of operation; data recovery. In practice, this has a few more layers of complication. Pages can be placed in different locations that enable wear leveling so one area of memory is not over utilized. There is also a table of bad blocks/pages that the micro knows to skip, and there is usually a bit or address in the page that is used to detect errors that may have occurred.

    This is pretty much everything I know on the subject. Hopefully it helps you understand the abstract nature of what is happening. In the simplest of terms, flash memory is like writing a long essay with an ink pen and where you can not make mistakes or use whiteout. If you need to make a change, you must write out the entire page all over again. This process is what is so time critical that you must “eject” the drive.






  • It follows the first to market principal in many of the most active communities, and it is the most federated instance. Many instances that are not federated with each other are federated with .ml. You still won’t see those comments between instances. Like from my main account here on .world, I can’t see hexibear or beehaw stuff, but from my .ml account I can see them. I have accounts on many instances in order to help federate new communities and to check biases/instance behaviors.

    I came over a few days before the rexodus and subscribed to the active communities before the influx. That sub list is still centered around the most active communities, and the majority of those are from .ml and before I joined Lemmy.

    Instances all have different flavors. I don’t like using my .ml account as a main. I’ve tried it. But I find they are the center of the most interesting and productive conversations for a more broad audience, while Beehaw has the most positive and friendly conversations overall. The main benefit to .world is the speed of connectivity, general audience scope, but with a strong anti asshat policy.




  • Not sure. There was some controversy with some of the devs making alt front ends and admins complaining about the slowness. I’ve seen mention of one of the two devs learning Rust just to participate. So it is not entirely a walled garden. The front end devs wanted to make an alt from scratch but in something like JavaScript although I don’t recall the details exactly. There were a lot of red flags related to privacy and understanding the community at large in the posts I saw from them. When asked why they weren’t adding pull requests with Rust in order to address their complaints I got no reply.

    All that said, I’m no dev. I can read in to around half the code I come across if I really try, and can successfully modify maybe half of that if I spend a few days on it, but I suck at clever code and the DRY cult types. I haven’t tried to look into Lemmy in any depth beyond figuring out the basics.


  • The Lemmy algorithm:

    https://join-lemmy.org/docs/contributors/07-ranking-algo.html

    The instances communicate between each other using special bots in the background that transport info between instances. Dot world is too big and makes too many requests to other instances. Most instances are reducing the number of transport bots back to dot world right now. There is supposed to be a fix in the next Lemmy version, but the code base is somewhat slow moving due to only two devs and it is written in Rust. Rust is a hard language like C, and not too many here are able to contribute to it, even though it is like the new gold standard of code.

    So you might see a delay between posting and replies or the interaction may come in bursts that correspond with the transport bots carrying content between instances as the host admin have configured their instance.
