#Publikationsmanagement in der #OnePersonLibrary

Liebe #LISCommunity, aufgrund unserer #LeibnizEvaluierung war es etwas still hier in den letzten Wochen.

Heute haben wir eine Anfrage unserer Wiss., die im Kontext des #Informationsbudget|s steht.

Wer kennt sich mit #Zotero #DataStorage aus? #FDM in #Bibliotheken

Unser internat. vernetztes Team möchte eine institutsbasierte Lizenz etablieren, ich begleite gerne die Prozesse, es gibt aber viele rechtl. & admin. Fragen.

And my external hard drive died ... Great years of Work and memories lost so to a seemingly big I can't locate because the drive reacts but it sounds horrible and the PC doesn't recognizes anything...

Hopefully my USB sticks survive long enough til I can buy a new solid state this time... :/
1 TB of backups, works and or memories lost...
4 Month ago it just worked fine I guess the storage area got hotter as I expected or it's just its natural time to die after 13 years of service.

Remember to backup AS OFTEN and as MUCH as you can and not only on one medium.

@johncarlosbaez Ooooh!

So ... I've had a theory of ... stuff ... for a while, one aspect of which goes a bit like this:

Phenomena for recording or transmission of information have a modifiable regularity which can usefully generated, preserved or transmitted (for recording or signalling systems respectively), and detected.

Think of Schroedinger's "aperiodic crystals", a notion I'd first encountered ... maybe four decades ago. (Not sure if it was Hofstadter's Goedel, Escher, Bach or perhaps Jeremy Campbell's Grammatical Man, but mid/late 1980s, regardless.)

This means that there are certain phenomena which immediately suggest themselves as recording media or transmission channels. The regularity of a smooth stone, clay, or papyrus, parchment, or paper surface, for example, which can be etched or inked. Vinyl and polycarbonate can be etched with analogue waveforms or digital bit-patterns. The regularity of a magnetic medium whose polarity can be reversed. The regularity of a waveform, be it audio, radio, or optical. And the transmission channels of speaking tubes, RF waveguides, or fibre-optic strands.

EMF, masers, and lasers in this view are fairly readily apparent as possible transmission media, I realised after the fact.

And the extreme regularity of graphene suggests that it might be usable as an extremely thin, small-structured recording medium. The challenges I'd seen for this were how it might be transformed, whether or not those transformations were regular over time, and whether or not the transformations were nondestructively detectable. That is, can it be written, preserved, and read over time.

And this suggests to me that it might be one such method for doing so.

(I'm not the first person to think of graphene as a data storage medium. Though I'm not aware that there's been any successful practical demonstration as yet.)

Incidentally, transistor memory is sort of a curious exception to my recording-medium notion in that it consists of states which are (destructively) read, and which aren't particularly reliable, though they can be sustained through a destructive read/rewrite process.

And if not graphene, then perhaps something similar to it in which a regular lattice can be disrupted.

Related notion: the symmetry between records and signals as existing in space-time and energy-matter respectively:

  • Signals act to transmit an encoded symbolic message from a transmitter across space through a channel by variations in energy over time to a receiver possibly resulting in a record.

  • Records act to write an encoded symbolic message from a writer across time through a substrate by variations in matter over space to a reader possibly resulting a signal.

Toot.CatDoc Edward Morbius ⭕​ (@dredmorbius@toot.cat)This musing follows on a set of earlier thoughts on the symmetry between *signals* and *records*. **Signals** act to *transmit* an *encoded symbolic message* from a *transmitter* across *space* through a *channel* by variations in *energy* over *time* from a to a *receiver* resulting in a *record*. **Records** act to *write* an *encoded symbolic message* from a *writer* across *time* through a *substrate* by variations in *matter* over *space* to a *reader* resulting a *signal*. Again, there are hybrid forms as well, e.g., endocrine and chemical signalling systems are based on *records* (the encoded chemicals) but distribute much as *signals*. **Edits:** Lightly updated definitions: "reader" rather than "receiver" as end-chain for records, and resulting in their complements, as well as formatting. 2023-5-11.

"The Department of Government Efficiency (DOGE) announced Monday that the General Services Administration converted 14,000 magnetic to digital records, and claimed the process saved a million dollars a year.

@DOGE on X: The @USGSA IT team just saved $1M per year by converting 14,000 magnetic tapes (70 yr old technology for information storage) to permanent modern digital records.
The problem is, magnetic tapes are regarded by storage and archivist professionals as being a stable, reliable, and safe medium for long-term data storage. Just because it’s a 70 year old medium doesn’t mean those records needed a massive overhaul to digital, that it will save any money in the long term, or that the new storage method is better.

Casual storage enjoyers might hear tape and think fragile spools of plastic that can rot or wear out. But digital storage is not necessarily a better option if you’re trying to keep information for years; digital storage rot, or “bit rot,” can affect a hard drive over years of storage, making the data corrupt or inaccessible. This happens when the electrical charge inside a solid-state storage device—like the kind of digital drive we can assume DOGE is talking about—leaks and causes the drive to lose performance."

Welp. We just had a #SeagateExos #20TB die on us in a spectacular way.

It's not just dead. It's *really* dead. ZFS refused to actually replace it, and the drive wouldn't power on.

Luckily, I had a spare. So now it's resilvering and our 539 TB of used data is safe (assuming nothing else dies)

I'm in line for an #RMA because it was new in 2023. Of all the drives we've had in our video server, this is the... fourth I think to die since 2015.

off to RMA the bugger, then.

I would add to truly safeguard your data by keeping at least THREE copies--one in the Cloud, one on an external hard drive (which last longer than USBs) in your home, and a third either offsite or onsite, on a different hard drive.

Users have lost access to their own Cloud accts without explanation (especially Google). You can accidentally delete Cloud files, or want to revert to a previous version.

If you give anyone else a copy and ask them to be your offsite backup, LABEL your data storage.

I discovered this the hard way when my 10K+ files blew up. My laptop had died WHILE I was copying one backup to a secondary backup USB. ALL of my 10K+ files were GONE.

My 3 brothers had copies, and all of them had deleted my files and re-used the USB sticks, or simply lost the USB.

If I had not been married to a computer guy, I would've spent months in tears. Instead, I spent the next few months sorting out the recovered files.
