  • While I don’t exactly intend to run RAID, I ended up choosing nas drives for the 24/7 intended usage,

    The purpose of a NAS drive is to be LESS reliable than a regular drive, not more reliable. Explanation: if a regular drive gets a read error on a block, it will retry for quite a while before giving up. The host, meanwhile, has to wait for the data to be retrieved if the retries work. That’s all it can really do, wait and hope. Meanwhile, the waiting slows the application down.

    A NAS drive instead will fail once or twice, then give up immediately, since it knows that it’s in a RAID system and that the data is also present on other disks. The RAID then puts the data together from the other drives and gets it to the host, logging the error. It will also hopefully mark the bad block on the drive with the read failure, and rewrite the recovered data to a spare sector. So this is faster than all the retries even though the drive that had the bad block gives up on it rather than attempting recovery by repeated reads.

    So if you buy NAS drives, put them in a RAID.

    Drives are currently around 2x as expensive as a year or so ago but they are available if you can afford them. I guess that’s better than shortages where they’re hard to find even if you can pay. We’ve had that before too.

    I like to think the current situation will settle out. Who knows though. Drive space is still way less expensive than in 2010 or anything like that.



  • Um obviously it will depend on the cost, and tape in general these days is seen as an enterprise thing with prices to match. Are you going to make a tape drive? What about the tape?

    1TB isn’t that interesting since you can get LTO-5 or LTO-6 (1.5TB or 2.5TB native) fairly affordably these days. The physical size of the cartridge isn’t that important for most of us.



  • This appears to be about medical coding, nothing to do with writing computer software. When someone gets medical treatment, someone has to translate the treatment description into insurance billing identifiers, called “codes”. I don’t know anything else about it except that it takes a lot of training, and some effort goes into gaming the system to choose the most expensive codes for a given treatment. CPC stands for Certified Professional Coder.






  • I’d be interested to know if there’s a way to fix this issue with extensions. Do you mean browser extensions? I use a browser sometimes and newpipe sometimes.

    Using a browser and ublock origin, I find viewing youtube to work ok except for the occasional age gated video that I can’t view without a google account. What’s stopped working is search ordering and seeing timestamps. Like old comments might get labelled “2 years ago” with mouse-over no longer showing the actual date/time. It’s not shown in the unrendered HTML in any obvious way either.




  • Devastating? Jeez.

    If you want to make a code change proposal, go ahead and make one. Otherwise, deletion is a feature offered to Lemmy users to use as they see fit. In fact some earlier (unrelated) proposals to speed up the software were rejected on the grounds that deletion is required to actually scrub the entry from the database, rather than simply making it inaccessible through the web. The scrubbing requirement may have been abandoned by now though.

    I half remember a Lemmy client (Voyager Jerboa?) with a user setting to automatically delete any post or comment that the user makes after 7 days or something. It had nothing to do with karma. I didn’t use that setting but it seemed reasonable to me. Lemmy is a discussion forum not a long term archive.

    I do like the idea of adding a wiki feature to Lemmy, to hold info of long term value to a community. Reddit already has something like that.**






  • I remember being annoyed that the standard camera app required microphone permission and that caused me some hassle once. It obviously needs file permissions in order to save pictures. But, I don’t remember it requiring network permissions or anything else especially alarming.

    It shouldn’t need microphone permission for taking still photos, or for shooting videos without sound. I joke that Charlie Chaplin was able to make silent movies 100 years ago, but the technology for doing that now seems to have been lost.

    What other permissions does it want? What Android version? When I encountered this, it was on my old phone that ran Android 6 at the time (later Android 7).
