Community Rules
You must post before you leave
Be nice. Assume others have good intent (within reason).
Block or ignore posts, comments, and users that irritate you in some way rather than engaging. Report if they are actually breaking community rules.
Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.
Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".
Bigotry is not allowed, this includes (but is not limited to): Homophobia, Transphobia, Racism, Sexism, Abelism, Classism, or discrimination based on things like Ethnicity, Nationality, Language, or Religion.
Avoid shilling for corporations, posting advertisements, or promoting exploitation of workers.
Proselytization, support, or defense of authoritarianism is not welcome. This includes but is not limited to: imperialism, nationalism, genocide denial, ethnic or racial supremacy, fascism, Nazism, Marxism-Leninism, Maoism, etc.
Avoid AI generated content.
Avoid misinformation.
Avoid incomprehensible posts.
No threats or personal attacks.
No spam.
Moderator Guidelines
Moderator Guidelines
- Don’t be mean to users. Be gentle or neutral.
- Most moderator actions which have a modlog message should include your username.
- When in doubt about whether or not a user is problematic, send them a DM.
- Don’t waste time debating/arguing with problematic users.
- Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
- Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
- Ask the other mods for advice when things get complicated.
- Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
- Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
- Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
- Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
- Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
- First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
- Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
- No large decisions or actions without community input (polls or meta posts f.ex.).
- Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
- Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

A BURNT cd isn’t lossless so that’s just plain false mate….
Bloviate about whatever, but dude asked about burning a cd, you made a comment about vinyl which can be lossless, while a BURNT cd never will. A bought cd yes, as I did already clarify.
Wouldn't that statement depends on various factors?
Was the master digital?
Was the CD ripped at 44,1 kHz and 16-bit resolution?
Was the CD burnt according to the same parameters?
If all of those are true, then one could say that the burnt CD is lossless.
you keep making up standards and strawman here to make your point. Do what you want man, I’m out.
Making up “Standards”? It’s a principle of burning discs, it’s not lossless like you are falsely claiming it is.
Vinyl has more fidelity than a BURNT disc, even if you got a hold of the master recording and burnt it your self. It will not be a lossless transfer. Unlike bought cds and vinyl.
*new vinyl.
Since playing vinyls isn't lossless.
Neither is playing a disc. A vinyl has more fidelity than a burnt disc with crappy lossy files. I thought a topic about burning people would understand the basics of file transfers loss, downloading loss, and burning losses. But clearly some people just want to insult people, I thought buddy was asking g a legit question, turned out they wanted to insult someone while not even understanding the basics of the topic at hand.
Does the laser damage the CD?
👍
A CD, burned or pressed, will be a replication of the source as presented in a digital format. If you have to covert true analog sound to digital then the sampling rate will have some technical loss, though not perceivable to most humans.
A digital to digital copy will be a 1 to 1 replication of the data, there's no expectation of loss other than perhaps physical error of the drive, which even pressed disks can suffer from if the stamper is worn.
Edit Source: literally worked in a optical media replication plant back when DVD was still a fairly new thing. It starts off making a glass master disk in a clean room. From that, a positive metal stamper plate is created for production runs, tested periodically to verify the output still matches the master dataset. Once the metal stamper is worn to the point of causing errors it is replaced.
Burned disks are functionally identical to pressed disks in operation but work by darkening bits in the media layer. They degrade easier because of the photo sensitivity needed to let the laser change their state.
You are mostly right, except this line. And I think I understand your meaning but I think it's a little misleading.
A digital to digital copy can be a 1:1 replication. But just saying "digital to digital" doesn't mean the copy process is lossless, there are a ton of lossy transfer methods. I don't believe they are used when burning CDs (honestly not sure, but I googled it real quick) but just because it's digital doesn't mean it can't have losses
Assuming there's no conversion I might have added in. Yes if you change from wav to mp3 or similar there will be changes. A disk image copy, or even placing a digital file onto a disk doesn't alter the content regardless of burned or pressed, only the method of storage. A hash of the file should return the same regardless assuming no errors in the writing.
Every file transfer creates some noise and loss to the file. Unless you’re using high quality Flac files, which not everyone burning and downloading files are doing so, or it’s already been converted or transferred and incurred corruption.
If you transfer an mp3 1000 times, it’s gonna degrade. You can’t use hashes to fill in missing audio portions like you can with text or something.
Every time you transfer a file, there is loss, this isn’t unique to audio files. Your entire comment is wrong. Even downloading a file online won’t create a perfect copy of the audio file because of data loss, even with hashes.
