Hi, folks!
I was thinking about having some separate systems inside a single one, and I'd like to know what are the ways of doing that.
I know I could do separate root partitions and a single kernel (or a few) and switch via systemd-boot, but that would require rebooting. With M.2 drives booting up a system is fast, but I'd like to explore other possibilities.
The end goal would be to have some isolated systems, which could use the same kernels in the EFI but have different root file systems, and possibly individual home directories to keep the isolation which in all of those could link to a separate partition (or BTRFS subvolume, as it's the file system I use) to keep some things that I'd like to share among these.
This way, I could have a minimal system for work, one for personal use, one for trying stuff out, and the packages could all be different as well as the configuration, and I'd like it to be easily hot swappable if possible, such as running a script to switch and not having to reboot unless I want to, for updates, or to switch to a different kernel.
Is this a job for something like systemd-nspawn or are there different ways to do that? Are containers or KVM my only option here?
I know there's the person here that did the immutable system using Arch, so I know there's a bunch of knowledge on this sub and very cool ideas, if anyone could point me in the right direction and elaborate a bit on the pros and cons, I'd appreciate it.
Hope everyone is having a really nice weekend. Stay safe.
A perfect isolated system likely does not exist, I know that. But what is the closest that we humans have gotten to creating one? My best guess would be experiments on the ISS or other satellites.
And what is the value of having slight improvements in how isolated a system is?
(Google isn't being of much use to me.)
Hi! I moved alone to a new town in late summer 2019 to attend school, and didn't make friends before COVID hit. I'm taking a lot of distance from the one person I did have a close connection with because eventually it didn't feel good to put them under the pressure of being my only local friend at such a high-stakes and stressful time. Only having one relationship to depend on is really the hard opposite of RA.
So I'm here with a blank slate, trying to unlearn the loneliness I've felt all my life. Prolonged isolation is touching a lot of wounds from the past about not fitting in or feeling invisible, and I am emotionally leaky and talk too much in Zoom school or whenever I speak to someone in real life. I gotta get my own boundaries under control while still meeting my need for social interaction and emotional connection in some way that doesn't bug other people.
From an RA framework, or your personal experience:
What can I do to prepare myself to be social and find a supportive community? (whenever that is finally possible)
Also: What are some other ways of seeing this situation?
and, What would you do if you were experiencing this?
I like to experiment with different settings and install tools to try them out. Downside of that is, when something goes wrong I often don't remember what I did and what I should do to revert it and go back to previous system state. I'm wondering if there is some kind of linux sandbox or "reversible bash" so it would track all changes I've made and eventually revert them?
Sorry for the length.
So my band are thinking about doing an Isolated IEM system for when gigs return, We have an X32 rack mixer already & just need to buy some IEM transmitters/receivers & the splitter.
Just looking for advice from Live sound guys as to what would cause the least fuss in our system for setup/packdown in shows with multiple acts.
We'll have an 8 channel Isolated splitter for our X32 with the following channels/mics
1: Kick (Audix D6)
2: Snare (SM57)
3: Drum Trash/audience mic (SM57)
4: Bass DI (DI off Darkglass Head)
5: Guitar L DI (Speaker sim output)
6: Guitar R DI (Speaker sim output)
7: Lead Vox 1 (beta 58)
8: Lead Vox 2 (beta 58)
Would having a patch panel on the rear of our rack to plug into the stage box (extra XLR cables would be needed which we would bring) or a pre-made labelled snake be easier for changeovers & Setup time?
We also own all of the mics in the list so would bring them to each show for consistency in our IEM mix
The consitency & accuracy of an IEM system would help our vocal performances especially and so its a route we would really like to go down, Our drummer would likely still be on wedges as he doesn't sing & prefers them.
Are there any suggestions you guys would have for making this system as unintrusive for FOH guys as possible? The setup as described I wouldn't expect to take too long for changeovers & the provided mics would normally work in a live setup.
Looking forward to hearing all your suggestions, Cheers!
I'm a 4th year apprentice, have been on this sub for a while now. I've been working on wiring operating rooms for a major hospital for the last couple months, and we're now starting to pull wire. We actually pulled a bunch of THHN, only to find out it was going to all need to come out. That was my friendly introduction to isolated power systems.
I'm trying to grasp this concept, I get that the point is to eliminate the low impedance ground fault path found with conventional systems. My biggest point of confusion is maybe that I don't understand how devices are able to function the same way without the neutral conductor? Can anyone give me a good overview of these isolated 120V power systems?
About a year ago I had FFS. I wasn't happy with the outcome, especially my forehead and nose. I recently had them revised and now I'm dealing with some of the same emotions and frustrations I had after my first surgery. It's hard for me cope with surgeries. I have health anxiety and having giant scabby wounds triggers it. Also, I'm currently very, very swollen so my face looks unnatural right now.
I'm definitely no beauty queen after this revision and that's something else I have to accept. This is probably the best looking I can get short of doing hair transplants. It's pretty disappointing when I see women coming out of FFS looking like models and I'm stuck looking like... well... looking like me. After two rounds of face surgery I look like my closet female relatives: my mom and aunts and her side.
I'm probably at the limit of what I can have done to surgically alter my face. I now have a type 3 forehead surgery which is as aggressive as it gets. My orbital rims were improved but my eyes are still deep. They'll always be deep because of the shape of my skull. Revision jaw surgery is off the table, too. My original jaw shave came very close to damaging my inferior alveolar nerve. There is not enough room to do a sliding genioplasty now. My only option at this point is probably a chin implant for my receded chin and, if I want to go to extremes, a Lefort 1 to try to shorten my midface. To be honest I haven't ruled those out but I'm quite tired of face surgery.
Anyway, my network of trans friends seems to be getting less and less interested in providing support. I feel like I've always been there for them. I'm really sorry that some people can't afford one let alone two rounds of facial surgery but that doesn't make my issues less real. I'm running of places and people to turn to for support.
I don't know what I'm hoping to get out of this. Thanks for reading.
