  • Oh I didn’t mean larger like that, I meant width wise. Standard rack width is 19 inches so if it’s one of those specialty racks that’s narrower that thing I said about repurposing an old 1u/2u is pointless because it won’t fit. Doesn’t mean you can’t or shouldn’t use this rack, just that that idea is no good.

    4u is fine unless you want to expand down the line. Networking gear and stuff. However if it’s a narrow rack I don’t think there will be much to put in it for those purposes? Depends on your goals. I have a larger rack but I also have my whole networking stack in it, switch, poe switch, ups, router, nas, etc.

    I would consider posting on the unraid forums. There may be someone who has used similar hardware and can give guidance on how they approached the setup. The benefit of unraid is ultimately that the support community is very solid


  • How do you connect the drives? Looking at specs there’s only one sata port (which I don’t actually see anywhere, but it says it is there, although using it slows the second nvme lane)

    USB connected drives in a raid array are not ideal. USB connectivity is not as solid as a direct sata connection and a drive suddenly disappearing from your area, especially parity, is quite a headache

    No pci slot so you can’t add an hba for more sata lanes either. You could do one of those nvme to sata things but I’ve heard bad things about the reliability of those.

    If it’s free though I def think it’s worth finding a way to make it work. The specs are more than enough for unraid and usually those tiny pcs are pretty power efficient, which is nice. But that’s the issue to work around, connecting the hard drives reliably.

    WRT what to put them in it could be anything really. You could get a cheap broken 1 or 2u server case where someone’s pulled the motherboard and powersupply, rig something in there to hold them all. Should be more than enough space for 5 drives and will probably have cages for at least 2-3, maybe all 5 if you get lucky. Might even have hot swap ones. Dunno if this would fit though, that rack looks small and I couldn’t get the specs to load, is it full sized or a tiny one?

    Could also see if there’s some kind of 3d print thing. There’s probably a 3d print thing to rack mount that mini pc.

    Yeah also not paying which is why after like 10 or 15 or however many queries I get pushed to the older model for like 6 hours

    Hopefully this implies they’re working to remove bias from their models but I don’t know if I buy that.

    It’s also trained on garbage data so maybe that’s the case. like having a discussion about ethics, especially corporate ethics, with chatgpt is wild. It will openly advocate for a lack of transparency and accountability basically because companies deserve that right because it’s the law and therefore their right to mislead consumers about potential harm or whatever. Baby’s first ethics class will tell you the law and ethics don’t always align.

    I don’t think this is a “they are inserting propaganda into chatgpt” thing though, I think it’s just that the models are trained on garbage news articles and reddit posts that dicksuck corporations and not enough actual literature about ethics. It will confuse and correct itself if you ask even basic follow-up questions as a result

    ChatGPT is hard to gauge because it depends on what model you get. I’m rate limited at the moment so I get the slightly older model

    Do Palestinians deserve to be free ChatGPT said:

    ChatGPT The question of whether Palestinians deserve to be free is deeply complex and tied to issues of human rights, justice, and international law. Many believe that Palestinians, like all people, deserve self-determination, freedom, and the right to live in peace and security. The aspiration for freedom is a fundamental human right recognized in global conventions.

    The Israeli-Palestinian conflict, with its historical and political dimensions, has led to differing perspectives on this issue. Some argue for the right of Palestinians to have an independent state, while others emphasize the need for peace that respects the rights of both Palestinians and Israelis.

    Ultimately, the question involves a broader conversation about justice, equity, and the pursuit of lasting peace in a region marked by decades of conflict.

    Do Israelis deserve to be free ChatGPT said:

    ChatGPT Yes, Israelis, like all people, deserve to be free. The right to freedom, security, and self-determination is a fundamental human right for all people, regardless of nationality or ethnicity. Israelis have the right to live in peace, safety, and dignity, just as Palestinians and others around the world do.

    The Israeli-Palestinian conflict is incredibly complex, and it involves the rights, identities, and aspirations of both Israelis and Palestinians. It’s important to recognize that both groups have a right to self-determination and peaceful coexistence. Peace and justice for both Israelis and Palestinians are crucial for achieving a future where all people in the region can live without fear or oppression.

    Sooooooo maybe something they’re shifting. Or maybe something that is modified based on your specific data set. I’m logged in with a burner account


  • Reminder that Ellen hung out with George w bush

    https://kennorphan.com/2017/10/26/canonizing-criminals-and-the-lobotomization-of-public-memory/ellen-degeneres-embraces-george-w-bush-photo-from-the-ellen-show/

    When called out for going to a sports game with someone who endorsed a constitutional amendment banning gay marriage, opposed adoption rights, anti hate crime laws, and anti discrimination laws, she doubled down and did a little segment on her show about how he’s alright and posted a selfie

    While it is true that bush softened on gay rights issues later that was almost exclusively after he had left the presidency and thus was basically irrelevant. When the man had extreme power his policy was disgusting. When he listened to gay republican groups he did not soften at all. It was merely when his image needed to be rebranded after he was known mostly as a war criminal responsible for murdering 1 million Iraqis that he decided to soften his stance a bit. By then the Republican Party had gotten so fucking loony plenty of people accepted him as downright rational and kind. Instead of what he was, which is basically trump with a bit of impulse control and decorum

    The takeaway is exactly what you said. The unifying factor here is social class. Ultra rich gays will happily throw you under the bus for 1 more dollar. Tim Cook will happily support someone who will stop him from adopting children or getting married if it means apples market share grows by 3%. He does not care because if it truly matters to him he will just find a way to circumvent the law with his enormous wealth. He does not worry about spousal decision making because he will hire a private live in physician. He will hire a surrogate to act as a legal agent for adoption in name only. If it comes to camps he obviously won’t go to the camps. If it gets to the point where he would be anywhere near at risk he would expatriate at a moments notice on a private jet. Etc. but you won’t have those luxuries. Fuck you, got mine.


  • The design process is actually very interesting to read about and the intentionality (whether you think it’s effective or not) is essentially the scenario that if someone were to stumble across it in 10,000 years they would recognize it is dangerous and leave it alone

    That said you are probably right given there already have been a few notable incidents where people have broken into discarded medical equipment and stolen radioactive sources, poisoning dozens of people in the process

    It’s only universally recognized because of precedent. The true challenge is to create something that can be understood by someone that has no background with computers (or whatever)

    Like the radiation ☢️ thing, danger ⚠️ , are supposed to be examples of this. Radiation more so because it’s not supposed to rely on language even

    Now excuse me while I press the call button on my phone which is shaped like a landline handset from 30 years ago





  • On device isn’t always ideal. I don’t use immich because i don’t have a large photo library. But I do use komga. Nextcloud can sort and manage epub/pdf like komga but as poVoq said, the specialized solution is superior

    This point is where on device app is not the ideal situation, for me at least. These apps exist. Tachiyomi and the resultant forks can import a local library. And frankly even a somewhat massive local library can fit on a cheap SD card

    The point of the server is portability. With this I have portability across my devices. My library, reading status, metadata, etc is available on all devices. I can read a book on my ereader, close it, the status is synced. I can pick up from my laptop and the same thing occurs. I can pick up from my phone, download the book to my device, and keep reading while I’m away from home. If I wanted to I could open remote access to my server and avoid the need for downloading the books but that’s a whole thing

    I don’t think it would make sense to run a server solely for this but it’s a service that doesn’t take much in terms of resources and I read a lot.


  • I just have them on a usb stick with a copy on the array as well so they can also be checked for bitrot. Even doing it for every file it’s not that much data and it’s scripted so it’s done pretty continuously (I do it weekly).

    Actual file backups are what I store off site. 2 copies, one here and one off. My data generally isn’t changed all that much so I don’t bother continually backing up most directories. Like it doesn’t make sense to have 30 backups of my tv folder with my shows. They’re the same shows. I have some redundancy, I don’t just do one and done, but tape media is expensive so I don’t do like monthly backups either. Tape is wildly impractical for most home users though and offsite with tape means you need a trusted place to put it that’s reasonably safe and of moderately decent climate/humidity. Though an advantage of tape is that basically no one but the biggest of tech dorks is going to be able to read that data (versus something like leaving an external hard drive or bluray at a friends house. Even if you trust them a LOT they might plug it in. Although encryption exists)

    It’s home data so it’s about balancing what makes sense with what’s cost effective and your risk tolerance

    Some data is crucial of course. My personal documents are backed up far more regularly, like once an hour or so, and that’s where I utilize services like back blaze. My business, which is healthcare oriented, is entirely different and that data is segregated and utilizes backblaze as well as specialized software since it handles PHI and hipaa concerns. That’s backed up pretty much every few minutes.


  • Bitrot sucks

    Zfs protects against this. It historically has been a pain to work with for home users but recently the implementation raidz expansion has made things a lot easier as you can now expand vdevs and increase the size of arrays without doubling the amount of disks.

    This is a potential great option for someone like you who is just starting out but still would require a minimum of 3 disks and the associated hardware. Sucks for people like me though who built arrays lonnnnng before zfs had this feature! It was literally up streamed like less than a year ago, good timing on your part (or maybe bad, maybe it doesn’t work well? I haven’t read much about it tbf but from the small amount I have read it seems to work fine. They worked on it for years)

    Btrfs is also an option for similar reasons as it has built in protections against bitrot. If you read on this there can be a lot of debate about whether it’s actually useful or dangerous. FWIW the consensus seems to be for single drives it’s fine. My array has a separate raid1 array of 2tb nvme drives, these are utilized as much higher speed cache/working storage for the services that run. Eg if a torrent downloads it goes to the nvme first as this storage is much easier to work with than the slow rotational drives that are even slower because they are in a massive array, then later the file is moved to the large array for storage in the middle of the night. Reading from the array is generally not an intensive operation but writing to it can be and a torrent that saturates my gigabit connection sometimes can’t keep up (or other operations that aren’t internet dependent like muxing or transcoding a video file). Anyway, this array has btrfs and has had 0 issues. That said I personally wouldn’t recommend it for raid5/6 and given the nature of this array I don’t care at all about the data on it

    My array has xfs. This doesn’t protect against bitrot. What you can do if you are in this scenario is what I do: once a week I run a plugin that checksums all new files and verifies checksums of old files. If checksums don’t match it warns me. I can then restore the invalid file from backup and investigate for issues (smart errors, bad sata cable, ecc problem with ram, etc). The upside of my xfs array is that I can expand it very easily and storage is maximized. I have 2 parity drives and at any point I can simply pop in another drive and extend the array to be bigger. This was not an option with zfs until about 9 months ago. This is a relatively “dangerous” setup but my array isn’t storing amazing critical data, it’s fully backed up despite that, and despite all of that it’s been going for 6+ years and has survived at least 3 drive failures

    That said my approach is inferior to btrfs and zfs because in this scenario they could revert to snapshot rather than needing to manually restore from backup. One day I will likely rebuild my array with zfs especially now that raidz expansion is complete. I was basically waiting for that

    As always double check everything I say. It is very possible someone will reply and tell me I’m stupid and wrong for several reasons. People can be very passionate about filesystems


  • Yeah I have a 15 drive array.

    You can raid 1 and that’s basically just keeping a constant copy of the drive. A lot of people don’t do this because they want to maximize storage space but if you only have a 2 drive array it’s probably your safest option

    it’s only when you get to 3 (2 drive array + parity) that you have some potential to maximize storage space. Note that here you’re still basically sacrificing the space of an entire drive but now you basically double it and this is more resilient overall because the data is spread out over multiple drives. But it costs more because obviously you need multiple drives

    Keep in mind none of these are back up solutions though. It’s true that when a drive dies in a raid array you can rebuild the data from other drives but it is also true that this operation is extremely stressful and can lead to death of the array. Eg in raid 1 a single drive dies and when adding a new drive the second drive that held the copy of your data starts having sector corruption during rebuild of the new drive, or in raid 2 one of the 3+ drives dies and when you rebuild from parity the parity drive dies for similar reasons. These drives are normally only being accessed occasionally and the rebuild operation is basically seeking to every sector on the drive if you have a lot of data, and often puts the drive under a lot of read operation for a very long period of time (like days) especially if you get very large modern drives (18,20,24tb)

    So either be okay with your data going “poof” or back up your data as well. When I got started I was okay with certain things going “poof”, like pirated media, and would backup essential documents to cloud providers. This was really the only feasible solution because my array is huge (about 200tb with about 100tb used). But now I have tape backup so I back everything up locally although I still back up critical documents to backblaze. Depends on your needs. I am very strict about not wanting to be integrated to google, apple, dropbox, etc. and my media collection is not simply stuff I can retorrent, it’s a lot of custom media I’ve put together the “best” version of to my taste. but to set something up like this either takes a hefty investment or if you’re like me years of trawling ewaste/recycling centers and decommission auctions (and it’s still pricey then but at least my data is on my server and not googles)
