  • Blockchain isn’t really a great storage mechanism for large files, it is good for small transactions/records. This is why most NFTs are just links to content instead of storing the content in the blockchain itself. It is possible to store that data in the chain but you usually pay transaction fees based on the size of that data. To store the data in the chain everyone participating in the chain would need a full copy of every video posted which isn’t really feasible long term.

    It is also nearly impossible to moderate. i.e. how do you remove illegal CSAM content from something that is designed to be immutable.

    So storing data like this is just not the right use case for blockchain.

    Someone could create a site based on a blockchain where you distribute links to videos, but those links would still need to be stored somewhere else. You really aren’t gaining much beyond just hosting the content yourself.

    The only valid use case would be if you are attempting to avoid government influence that might try to modify your content later, or able to prove that you are the one posting the content. You could use the blockchain to post a link to a video and the hash of the file to verify it is the correct file, then anyone with access to the chain would have a record of who posted it and a way to validate that the content hasn’t been modified.

    There are federated options like PeerTube that are close to what you want but without the blockchain issues.

    +1 to this. Lots of talk in this thread about drivers, but the only driver involved here is the Bluetooth driver. Half of the point of Bluetooth is that peripherals don’t need their own drivers, they just provide various profiles which are standardized so the Bluetooth service can consume those profiles from any device.

    Not an expert in this area but I believe the implementation of most of those profiles is user space, so the proper place to be debugging is the Bluetooth service or in pulsesudio. So start your Bluetooth service logs they might give you some idea as to what is going on. Try to get a list of what profiles are supported by your OS and what profiles are supported by the device, maybe the device only supports some newer lossless profile that hasn’t been implemented in Linux yet.

    I think they worded that backwards and are referring to the adage (or maybe that is what the banks go off of?) that your loan shouldn’t be for more than 3x your income. So if you make 80k per year you can generally afford a $240k house.

    Going above that 3x means too much of your income goes to paying for the house and you don’t have enough for other living expenses+maintaining the house.





  • I don’t use the WebOS app but generally default subtitles/audio languages are set on your profile and the apps pick up those settings.

    Try logging in to the web interface and going to your user profile. There is a “Playback” section where you can set your preferred languages. If this isn’t set it likely is taking the default language from your media files instead.




  • Unauthorized VPNs (non government approved) are illegal in China. If a business needs their own they can get approval but they have to apply for those exceptions.

    It isn’t really enforced, probably especially so for non citizens, but if you do something they don’t like it is something they could use against you.

    You would probably be less breaking the law to just directly open up SSH and access that instead of tunneling through a VPN. Even though SSH can do tunneling of its own.


  • Your $1 has absolutely changed in value by 10pm. What do you think inflation is? It might not be enough change for the store to bother changing prices but the value changes constantly.

    Watch the foreign exchange markets, your $1 is changing in value compared to every other currency constantly.

    The only difference between fiat and crypto is that changing the prices in the store is difficult, and the volume of trade is high enough to reduce volatility in the value of your $. There are plenty of cases of hyperinflation in history where stores have to change prices on a daily basis, meaning that fiat is not immune to volatility.

    To prevent that volatility we just have things like the federal reserve, debt limits, federal regulations, etc that are designed to keep you the investor (money holders) happy with keeping that money in dollars instead of assets. The value is somewhat stable as long as the government is solvent.

    Crypto doesn’t have those external controls, instead it has internal controls, i.e. mining difficulty. Which from a user perspective is better because it can’t be printed at will by the government.

    Long story short fiat is no different than crypto, there is no real tangible value, so value is what people think it is. Unfortunately crypto’s value is driven more by speculative “investors” than by actual trade demand which means it is more volatile. If enough of the world changed to crypto it would just as stable as your $.

    Not saying crypto is a good thing just saying that it isn’t any better or worse. It needs daily usage for real trade by a large portion of the population to reduce the volatility, instead of just being used to gamble against the dollar.

    Our governments would likely never let that happen though, they can’t give up their ability to print money. It’s far easier to keep getting elected when you print the cash to operate the government, than it is to raise taxes to pay for the things they need.

    The absolutely worthless meme coin scams/forks/etc are just scammers and gamblers trying to rip each other off. They just make any sort of useful critical mass of trade less and less plausible because it gives all crypto a bad name. Not that Bitcoin/Ethereum started out any different but now that enough people are using them splitting your user base is just self defeating



  • Nope, the switch only keeps saves on the internal storage or synced to their cloud if you pay for it. When doing transfers between devices like this there is no copy option only a move and delete.

    There are some legitimate reasons they want to prevent this like preventing users from duplicating items in multiplayer games, etc. Even if you got access to the files they are encrypted so that only your user can use them.

    I think the bigger reason they do this is there are occasionally exploits that are done through corrupted saves. So preventing the user from importing their own saves helps protect the switch from getting soft modded.

    If you mod your switch you can get access to the save files and since it has full access it can also decrypt them, so that you can back them up. One of several legitimate reasons to mod your switch.


  • I just did a playthrough recently and I think it holds up pretty well. A lot of wasted time on little cutscenes like opening Atla/boxes, and switching characters that gets quite annoying, but gameplay was fine.

    One or two bosses that are difficult but a little leveling up, or wiki hints on how to cheese them, and they are a piece of cake. Once you hit the ship dungeon and have easier access to backrooms (since you can buy the fish to enter them) you can grind for gemstones and you end up being able to one hit almost everything from there on out.

    Grinding gets a bit boring after a while, I’ll admit I enabled some fish point cheats in my emulator after I had one character with a maxed out weapon. Clear that I could easily do it myself but wasn’t going to waste that time to upgrade the other weapons I wanted leveled up.



  • Named volumes are often the default because there is no chance of them conflicting with other services or containers running on the system.

    Say you deployed two different docker compose apps each with their own MariaDB. With named volumes there is zero chance of those conflicting (at least from the filesystem perspective).

    This also better facilitates easier cleanup. The apps documentation can say “docker compose down -v”, and they are done. Instead of listing a bunch of directories that need to be cleaned up.

    Those lingering directories can also cause problems for users that might have wanted a clean start when their app is broken, but with a bind mount that broken database schema won’t have been deleted for them when they start up the services again.

    All that said, I very much agree that when you go to deploy a docker service you should consider changing the named volumes to standard bind mounts for a couple of reasons.

    • When running production applications I don’t want the volumes to be able to be cleaned up so easily. A little extra protection from accidental deletion is handy.

    • The default location for named volumes doesn’t work well with any advanced partitioning strategies. i.e. if you want your database volume on a different partition than your static web content.

    • Old reason and maybe more user preference at this point but back before the docker overlay2 storage driver had matured we used the btrfs driver instead and occasionally Docker would break and we would need to wipe out the entire /var/lib/docker btrfs filesystem, so I just personally want to keep anything persistent out of that directory.

    So basically application writers should use named volumes to simplify the documentation/installation/maintenance/cleanup of their applications.

    Systems administrators running those applications should know and understand the docker compose well enough to change those settings to make them production ready for their environment. Reading through it and making those changes ends up being part of learning how the containers are structured in the first place.


  • For shared lines like cable and wireless it is often asymmetrical so that everyone gets better speeds, not so they can hold you back.

    For wireless service providers for instance let’s say you have 20 customers on a single access point. Like a walkie-talkie you can’t both transmit and receive at the same time, and no two customers can be transmitting at the same time either.

    So to get around this problem TDMA (time division multiple access) is used. Basically time is split into slices and each user is given a certain percentage of those slices.

    Since the AP is transmitting to everyone it usually gets the bulk of the slices like 60+%. This is the shared download speed for everyone in the network.

    Most users don’t really upload much so giving the user radios equal slices to the AP would be a massive waste of air time, and since there are 20 customers on this theoretical AP every 1mbit cut off of each users upload speed is 20mbit added to the total download capability for anyone downloading on that AP.

    So let’s say we have APs/clients capable of 1000mbit. With 20 users and 1AP if we wanted symmetrical speeds we need 40 equal slots, 20 slots on the AP one for each user to download and 1 slot for each user to upload back. Every user gets 25mbit download and 25mbit upload.

    Contrast that to asymmetrical. Let’s say we do a 80/20 AP/client airtime split. We end up with 800mbit shared download amongst everyone and 10mbit upload per user.

    In the worst case scenario every user is downloading at the same time meaning you get about 40mbit of that 800, still quite the improvement over 25mbit and if some of those people aren’t home or aren’t active at the time that means that much more for those who are active.

    I think the size of the slices is a little more dynamic on more modern systems where AP adjusts the user radios slices on the fly so that idle clients don’t have a bunch of dead air but they still need to have a little time allocated to them for when data does start to flow.

    A quick Google seems to show that DOCSIS cable modems use TDMA as well so this all likely applies to cable users as well.
