    If you are waiting for next stable version (probably to be called 15.1) I fear that it might take more than one year before it gets released. The ChangeLog of Slackware current has not yet shown any sign of feature
    freeze or first release candidate.

    Slackware 15.0 was released Februari 2022, almost 6 years after Slackware 14.2 was released. During the years, as Slackware has grown with more and bigger packages, the time between stable releases has increased.

    Thanks for the warning. Got current (2025-05-24) installed, X is working
    with the Rx7600xt and driving 4K no problem. I was reluctant but since
    I hardly ever push the OS envelope I should be OK with this until 15.1.
    Had to burn the iso to blu-ray though since the file is 4.6gb and that's
    too much for the DVD+R's that I use.

    During the years I have created my own custom Slackware installation
    medias with extra software packages and my own packages containing
    different settings like a fixed choice of keyboard (yes I also customize
    the installation scripts to minimum number of scripts asked and all those setup scripts at the end of installation to no questions at all asked).

    The original Slackware 14.2 did fit on a 4.5 GB DVD, but with my customizations i needed a dual layer 8 GB DVD. My custom Slackware 15.0
    does no longer fit on those 8 GB discs, they require a 25 GB bluray. My biggest added software packages are the texlive-docs and texlive-extra packages from slackbuilds.org, those packages alone are 1.6 GB and 2.1 GB after compression with xz.

    In the 21st century, I would say that optical media still has its
    advantages:

    For small amounts of data optical media is usually cheaper than USB
    sticks, but yes, there are USB storage which is bigger than any optical
    media out there.

    The "write once" feature of optical media on one hand means that it can't
    be reused, but on the other hand it makes it great for backup purposes
    and saving of reference data like an installation media.

    USB sticks has more become a replacement of floppies than a replacement

    A sore arm!!! One of the word processors came on 47 floppies, even if

    couldn't feel your arm at the end.

    It has a few "advantages" in some (very few) cases, yes...

    We're talking about pennies here. Nobody cares about that.

    Yes, great for backup purposes, and I use the media for that myself. As
    for saving of installation media, I disagree. You end up with a stack
    of discs that you'll never use again, which is just clutter. Put the installation software on a USB stick, install it (without needing to use
    an external/usb optical drive), and then re-use the USB stick for
    whatever else you want. Save the .ISO file on a large hard drive if you
    think you'll use it again. Or delete it. Easy enough to re-download if needed. Installs from USB stick are also faster than from a
    slow-reading optical drive.

    USB sticks has more become a replacement of floppies than a replacement
    of optical media.

    Agreed on the floppy side of that statement, but for installation and/or transport of data, I think they've replaced optical media as well. By transport, I mean something like getting some data from one computer to another, when the computers aren't networked together.

    But for data that you want to save as a reference, often as some kind of backup purpose, a stack of optical media still has its purpose.

    I hadn't used any blu-ray since the early 'failures' epoch and was
    surprised to see 'archival' quality printed on a small stack that I just bought. Don't really know what the 'archival' difference is but there
    seems to me a strong market for the 25gb frisbies.

    Assuming "archival" is not simply a word inserted by the marketing
    department without any backing, "archival" for optical media usually
    refered to the use of dyes that were supposedly stable over a longer

    The details, if they even exist, won't likely appear on any of the
    marketing material. You'd have to go find the equivalent of an
    electronic chip "data sheet" for the disks to likely find any details
    of "what makes them archival".

    "Stored data is engraved on a patented inorganic write layer rCo it
    will not fade or deteriorate. Engraving process renders these
    archival grade discs practically impervious to environmental
    exposure, including light, temperature and humidity"

    If that's in the marketing material, then that's as close to "what
    makes them archival" as you'll likely find there. And that is a longer
    worded version of "use of dyes that were supposedly stable over a
    longer term time range".

    Fot the price you can buy a cheap 1tb ssd and make it host 40 backups of your 25gb data, but what happens to things magnetic or electic during a
    pole flip?

    True, but what happens to your 40 backups when the SSD drive decides to
    give up the ghost. This is why real 'backups' require some form of redundancy, whether multiple SSDs so one failing does not erase
    everything, or plural copies on 'archival' bluray disks so one disk
    failing does not take out "the only copy of X".

    What makes them good backups is that you cannot accidentally
    delete an entire folder (got the T-shirts) ...they're not even in the computer once done.

    If your only copy of data X is only on a single disk, it is no more a
    "good backup" than if your only copy of X were on a single SSD or a
    single mechanical drive.

    The read only aspect makes them impervious to accidental overwrite.
    That has advantages, but does not make them "a good backup" alone.

    Removability makes for easier expansion to a larger number of disks.

    But neither rises to the level of "makes a good backup" without also
    including redundant copies.

    These kind of mtbf claims are bs. They're based on testing
    thousands of items for several months, seeing how many of
    them fail during that short time, and then figuring out
    a mtbf for a single item based on that measured failure rate.
    So what's wrong with that? Real-life example: in the
    early 1990s, a particular variety (I forget which) of
    IBM pc hard drives began failing all over the place.
    Turned out a seal on their lubricant chambers had
    corroded after a year or two. And, of course, IBM's
    initial testing for a few months detected no such problem,
    which only arose after a year or two. Their advertised
    mtbf had been something like a million hours.
    Any kind of such problem, that only arises due to aging
    components, is completely unobservable by these kinds of tests.
    Heck, if we determined the "mtbf" for humans by measuring
    the death rates for children, our life expectancy would
    probably be hundreds of years.
    All this is pretty easy to understand, and I'd guess
    manufacturers making such claims are knowingly lying
    through their teeth (and probably various other orifices).
    So I'd keep an eye out for such intentionally false claims,
    and avoid those manufacturers like the plague that they are.

    It's from Verbatim, not a fly-by-night outfit but I havent' found any
    'details' as to exactly what makes them archival.

    YYMV, and longevity likely differs from initial reliability, but
    after I had used Verbatim brand DVD+/-Rs and BD-Rs for some
    years, I got annoyed by somewhere around 10%-20% of my burn
    attempts becoming coasters--and buying a new drive because I
    suspected the laser was going blind. I bought three packs of
    Verbatim, PlexDisc, and MicroBoards 25G BD-Rs and kept track of
    how many coasters vs. good burns I got from each brand. Verbatim
    had a high coaster rate. The other brands had nearly zero
    coasters. I am basing my future purchase decisions on those test
    results.


    Sounds reasonable. By becoming coasters do you mean that right off the
    bat they were duds (failing verification) or that sometime later they
    failed to check out the content compared to the source? I haven't used
    enough of them in my life to constitute any form of database (maybe 200
    since they first appeared in the 90's).

    With the Verbatim BD-Rs that became coasters, the burn would fail
    and error out within the first several seconds.

    OK, so that's indirectly a longevity issue :-)))

    My first experiences with blu-ray were so bad that I never used any
    again, that is to say not until this last attempt which seems to be a
    whole new generation. It was like that with early hard drives too and
    now some new ssd's. I had bought a pair of Fujitsu 2.5GB spinners and
    both were total distaters. More recently one of my 4tb Team-Grp ssd's
    keeps coming up as having only 2gb capacity. Growing pains.

    I should add to my to-do list to find some of my oldest BD-Rs
    that are still around and make sure they can be read and
    uncompressed.

    The oldest DVD of any sort that I have is a windows-95 installer but I
    don't think it will even boot on my box (much less a full check).
