@tomshardware how much of that, if any, might be preserved in Archive.org?

Gizmodo: Will We Ever Solve the Problem of Losing Data?. “…for this Giz Asks, we asked experts in computer science, cybersecurity, and archival research to consider the idea of ‘permanence,’ specifically in the context of how we record, track, and store information. That is, is there such a thing as permanent data storage?”

GPT 5.6 deleted an AI Bro's files.

Making mistakes or malfunctions isn't surprising—what is surprising is how some AI enthusiasts give unsupervised access to productive systems without backups. 🤦‍♀️

Here's the reality: AI has no idea what it's doing. It's a highly sophisticated word completion system ≠ a sci-fi thinking machine.

I am experiencing this with #OpenZFS

➜  ~ sudo zpool status -x
  pool: ughetto
 state: DEGRADED
status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.
action: Replace the device using 'zpool replace'.

errors: No known data errors

This has already happened, but at a point where I didn’t mind losing the data, so I destroyed the pool and I recreated it from scratch, with no errors. Now, I would like to try to repair the corrupted data… Any tips? I would hate it if I have to throw away the hard disk, it’s less than one year old and I have been using it only for a couple of months… Is replacing the disk my only option?

IDrive.com lost all of my backup data. No user error. No support assistance.

Mashable: New ransomware wipes every file larger than 128 KB. “The ransomware contains a critical coding flaw that permanently destroys any file larger than 128 kilobytes rather than encrypting it. That threshold is smaller than a typical email attachment, meaning virtually every file that would matter to a victim — databases, backups, virtual machine disks, documents, spreadsheets — is […]

A Cursor AI agent wiped #PocketOS’ production database and backups in just 9 seconds after misusing a root API token, exposing serious risks in AI-driven coding and cloud setups.

🎉 Behold, the #miracle of Webminal! A single server with the horsepower of a #potato and RAM you'd find in a decade-old laptop, yet somehow it refuses to die—much like your uncle's Windows XP machine. 🤷‍♂️ Who needs modern #tech when you can survive on sheer stubbornness and the occasional data loss? 🚀

One DELETE Cascades To 3.5 MILLION Rows?!

PRODUCTION APOCALYPSE! Deleted ONE user and CASCADE deleted 3.5 MILLION rows across 4 tables! Orders, payments, everything GONE! This is the scariest SQL behavior! Watch this nightmare!

🎉 Oh, the wonders of #MariaDB #Galera #Cluster 12.1.2! 🎉 It promises bulletproof safety but instead acts like it’s on a mission to lose your precious data faster than you can say "network partition". 🤦‍♂️ Apparently, transaction consistency is just a suggestion, not a guarantee. 🐢✨

DELETE Without WHERE Deletes EVERYTHING?!

STOP RIGHT NOW! Forgot WHERE clause in DELETE? Your ENTIRE table is GONE! 10 million users DELETED in production! This is every developer's NIGHTMARE! Watch this disaster!

Yet another reason to not enable passkeys anywhere.

https://blog.timcappalli.me/p/passkeys-prf-warning/

TL;DR - If an idiot website uses your passkey to encrypt your data, losing/deleting the passkey will almost certainly mean losing your data.

Of course we should all be backing up our stuff locally instead of trusting cloud services, especially for irreplaceable things like pictures and movies, but lets be real, the average user doesn't.

Uups, that was lucky. I forgot that I canceled my VPS about a year ago and procrastinated migrating the data off of it for almost as long.

Well the contract would have expired at some time today. I just now removed the cancelation flag (for at least another month).

TRUNCATE Can't Be Rolled Back?!

Your brain will EXPLODE! TRUNCATE looks safe but ROLLBACK won't save you! Data is PERMANENTLY DELETED even in a transaction! This broke a production database! Watch the horror!

Nature: When two years of academic work vanished with a single click. “…in August, I temporarily disabled the ‘data consent’ option because I wanted to see whether I would still have access to all of the model’s functions if I did not provide OpenAI with my data.

Might be a good time to remind people that if you are expecting a winter storm and ice with potential for power outages, you might want to disconnect and remove any external hard drives, usb storage, etc from your computers to prevent #DataLoss and corruption. #data #Winter #Weather #Snow #WX #blizzard #arctic #poweroutage
