#systemadmin — Public Fediverse posts

Hi, I’m Rook. I’m a 30-something nerdy #trans vixen.

I’ve been doing #WebDevelopment, #programming, and #database stuff since I was a kit, and I'm still loving it.

Currently, I am recovering from #AutisticBurnout and dealing with multiple #ChronicIllnesses.

Previously, I worked with complex #automation and #robotics systems in #HealthCare, doing a mix of #UserSupport, #SystemAdmin, and #DataAnalysis.

At home, I’m constantly tinkering with #SmartHome projects using #HomeAssistant, building my own #electronics, and battling my #3DPrinting hardware.

I also enjoy running around as a big, silly #fox in the #Furry fandom. #Fursuiter

I’m #ActuallyAutistic, #AuDHD, and #ADHD. I’m a proud #transgender member of the #LGBTQIA #queer community,

The 4mm active coolers have arrived!

I’ve just finished the installation. Mounting them to the USBridge radiator was a precise task, but the setup is now ready. No more relying on passive cooling alone — it's time to see if these tiny fans can handle the heat during intensive KVM video processing.

Moving straight to stress testing. I’ll share the thermal benchmarks soon!

Implementation of snapshots in USBridge.

I designed the system as a standalone mechanism, isolated from the host OS. The key priorities are determinism and data protection.
No drivers or agents. The host has no physical ability to delete or modify snapshots—this provides protection against OS compromise or encryption tools.

I use the Copy-on-Write mechanism. Snapshots are created instantly, without duplicating immutable data. Immediately after creation, the snapshot is sealed as a read-only subvolume.
I have disabled the automatic deletion of old blocks. If space runs low, archive mode is used so that the history isn’t erased by the algorithm.
Data can be read on any Linux system (native Btrfs).

People be like:

> " Oh noes!! My site is hacked!! 😱 Why did this happen? ⁉️ "

Well… you were using Mastodon v3 from over 5 years ago. That’s half a decade ago. That could be a clue. 🤡

Meanwhile, Mastodon 5.2 has a known security issue. It’s not exactly critical (not easy to trigger), but support for it ends next month — January 2026.

May I suggest you upgrade!

The current build is 4.5.3 (the nightly build is 4.6).

Another day, another breach. The Congressional Budget Office confirms a hack, with whispers that an ancient, unpatched firewall is to blame. It's almost like patching is important or something. 😉 What's your biggest 'should've patched that' horror story? #TechNews #SecurityBreach #PatchManagement #SystemAdmin https://techcrunch.com/2025/11/07/congressional-budget-office-confirms-it-was-hacked/

Happy #SysAdminDay. 🎉💪🚀

I suppose I should write an #introduction. I mean, I've only been on the fediverse for five years. :P

Hi, my name is Martin, I go by DarkFox (or DarkFoxDK) on the internet. I'm in my mid-30's and I've been doing #WebDevelopment, #programming, and #database stuff since I was still in school.

Currently I'm working with complex #automation systems in #HealthCare, where I'm a bit of a jack of all trades, doing a bit of #UserSupport, #SystemAdmin, and #DataAnalysis.

At home I thinker with a lot of #SmartHome stuff, based on #HomeAssistant. This includes building my own #electronics and #3DPrinting stuff.

At times, I enjoy running around as a big silly #fox, as part of the #Furry fandom.

I'm also #ActuallyAutistic, #AuDHD, #ADHD, and part of the #lgbtqia #AlphabetMafia.
