What I have done to maintain the integrity of my Time Machine backups (to UnRAID, via SMB):
For the "sparsebundles break" issue:
* Back up to multiple targets. I use both mbentley's Time Machine Docker image (only one backup per source machine) and UnRAID's built-in Time Machine functionality (multiple backups of same machine allowed).
* Use spaceinvader1's macinabox Docker image to have a local way to `fsck_apfs` the above sparsebundles.
* When one irreparably breaks, delete it and replace it with a copy of a working one from another of the above targets.
For the "backups are incredibly slow" issue:
* One of the above targets is to an SSD.
* Use TheTimeMachineMechanic's "Speed" option after a backup to determine the slow spots. Look at patterns in "Current:" lines. Pumping the output to an LLM is very helpful here.
What you're seeing are the speeds of various multi-tier caches (RAM, intermediate SLC etc.) It cannot write to its main flash memory that fast. While it to the user looks like they just wrote 10 GiB in a single second, the SSD is internally still busy for another 10 seconds persisting that data. The actual real write speed of top-shelf consumer grade SSDs these days is somewhere in the vicinity of 1.5 GiB/s. Most models top out at half of that or less.
I bought this one when upgrading my desktop, it indeed delivers what it promises. 14.5GB/s on my tiny random desktop, it's impressive. Everything feels so instantaneous, my Linux desktop finally feels like a Mac :)
That's certainly impossible as even USB4 is only 40Gb/s~5GB/s, and of that you could only expect to get 32Gb/s~4GB/s. Or realistically even less due to overhead.
It is probably the speed of it being read into RAM.
Try entering sync right after copying to see how long it really takes
I have one of these, though I'm using with a USB 3.x port as that's what my desktop has. For me it's working fine, and for others with actual USB 4 ports it seems to be working properly for them.
Thanks to the Earth's gravity well, it is significantly less energy-intensive to deliver 100kg of mass from the moon to low Earth orbit, than to launch the same amount from Earth.
This is the reason for SpaceX's recent pivot to the moon. Musk sees an opportunity to rapidly build AI data centers in orbit using lunar regolith without, say, community opposition.
Land acknowledgements are the ultimate in virtue signaling; once they actually mean something, they suddenly end. Two overlapping tribal claims in New Brunswick cover 100% of the province. Thus, New Brunswick provincial employees ordered to not make land acknowledgements while working, because of legal case <https://www.cbc.ca/news/canada/new-brunswick/first-nations-n...>.
The counterfactual to virtue signaling is genuine, anonymous, or quiet action—acting on moral convictions without seeking public recognition or social status.
While virtue signaling is a public, often insincere display of moral superiority (a "recognition desire"), the true alternative is "walking the walk" through tangible deeds.
It _is_ performative (not sure it's nonsense) because it doesn't actually do or intend to do anything. It's cheap.
(I personally think it's also _disingenous_, because you can't undo things done 100+ years ago -- not because they are no longer "bad" but because you can't figure out how or who to undo it to, and you should instead focus on "who needs help today", because they are alive).
> It _is_ performative (not sure it's nonsense) because it doesn't actually do or intend to do anything. It's cheap.
Yes, that's my point. Once some risk—however small—came to be of land acknowledgements within New Brunswick actually having some legal or practical ramification, poof there they went.
Given how widespread tribal territorial claims are in Canada (the entire city of Richmond BC, for example), I expect more such prohibitions.
Unfortunately, I never got around to using it! I bought it with high hopes, but my Zip disks turned out to be so convenient and spacious that the VHS-backup need never arose.
That said, it's not too late... I still have my Amiga system in storage, and a VHS recorder.
>I bought it with high hopes, but my Zip disks turned out to be so convenient and spacious that the VHS-backup need never arose.
It's good to hear, in retrospect, that you were able to use a storage medium that did not even exist when Amiga were discontinued. Which type of interface for the Zip drive works with it?
(It occurs to me that Zip disks presumably offer the great virtue, otherwise absent as I understand it for Amigans, of PC compatibility.)
It's amazing, the things that can be done without what we would consider modern technology.
The 8-bit Guy recently released a video asking "What if everything still ran out vacuum tubes?" <https://www.youtube.com/watch?v=mEpnRM97ACQ>. Conclusion: A surprising amount of things we take for granted today would still be possible.
>How about all the rock stars killed over the years
With the exception of rappers, most musicians who die early die from overdoses, suicides, and such (the "27 club" <https://en.wikipedia.org/wiki/27_Club>), as opposed to being murdered.
Then your point doesn't make sense. As I said, musicians who die early (again, excepting rappers) usually die from self-inflicted causes, not violence from others. What is the connection between this and violent attacks on AI and/or AI people?
Commodore so slowly and ineffectually improving on the OCS didn't help, but the original sin of the Amiga was committed in the beginning, with planar graphics (i.e., slow and hard to work with, even setting aside HAM) and TV-oriented resolutions/refresh rates (i.e., users needing to buy a "flicker fixer"). It's like they looked at one of the most important reasons for the PC and Mac's success—a gorgeous, rock-solid monochrome display—and said "Let's do exactly the opposite!"
Iirc interlaced display and 6 bitplanes were a compromise to allow color graphics in 1985 with the memory bandwidths available at the time.
If it's a sin or feature can of course be debated but I remember playing games on an Amiga in the early 90s and until Doom the graphics capabilities didn't look outdated.
By 1992 with AGA however I agree, flicker and planar graphics(with 8 bitplanes any total memory bandwidth gains were gone) was a downside/sin that should've been fixed to stay relevant.
5 sins in 1992:
- 8 bit planar instead of chunky
- progressive display (vs interlaced)
- sound was not 16-bit
- should have been 68030 with mmu support (vs 68020ec)
- HD mandatory.
If they addressed this, the Doom experience would have run better on Amiga.
