The photographer Michael Weseley did a number of long exposures (>12mths iirc) of Berlin during the 1990s as it was being transformed after the fall of the Wall and subsequent reunification.
Viewed as huge prints in a gallery they were impressively detailed, as layers of various rebuilding and urban planning projects were revealed in varying degrees of transparency, depending on how long they took and how recent they were:
I'm running a ZFS NAS with mirrored 2 HDD vdevs. I've set the HDDs to spindown after 20mins using hdparm -S and this works fine under zfs. The drives (Toshiba N300s) take ~15s to spin up when something accesses them, and ime zfs has always handled this gracefully.
This vdev only contains data; it's not running the OS / root.
> “It leads to a new philosophy of physics that rejects the idea that the universe is a machine governed by unconditional laws with a prior existence, and replaces it with a view of the universe as a kind of self-organising entity in which all sorts of emergent patterns appear, the most general of which we call the laws of physics.”
Is this distinction as meaningful as it first seems; my assumption was that all 'laws of physics' are in essence only ever an expression of our current best understanding of these observed 'generalised patterns'?
By talking about the 'laws', it's easy to start treating these as though they are firm, a-priori rules, but my assumption was that - to physicists - these were always simply a short-cut way of describing a set of common, repeated and testable observations about the universe. Iow they were never 'rules' in the sense that they existed independent of the phenomena they were describing? I'm not a scientist, btw.
There may be multiple, different issues with Samsung parts at play here. The 900 series issues seem to have been addressed with a f/w update; the 870 EVO issues were - allegedly - caused by bad NAND and the devices needed to be replaced.
ofc part of the problem here is the lack of public acknowledgement / information from Samsung on these issues.
The SSDs in these machines consist of NAND chips soldered directly to the motherboard; the controller aspect is handled within the main M* SOC. As such there's no way that a company could offer an internal 'upgrade' or expansion to these drives.
A fuller instance of the first quote:
"Through careful and
thorough fault injection, we show that ZFS is robust to
a wide range of disk faults. We further demonstrate that
ZFS is less resilient to memory corruption, which can
lead to corrupt data being returned to applications or
system crashes"
...ie, ZFS is 'less resilient' in comparison to its robust disk fault handling, not that it's less resilient to memory corruption in comparison to other filesystems. The parent quotation above implies that ZFS is more sensitive to memory corruption than other fs but that is not claimed in the referenced paper.
The issue is not a cable thing. I have experienced the same behaviour on both a 2020 intel MBA and a 2021 M1 Pro; a 10GB/s rated Samsung T5 SSD only connects to either Mac at 5GB/s, despite being rated for 10GB/s. The same SSD (and cables) connects to Linux & Windows boxen at 10GB/s.
Equally, a Crucial X8 SSD rated for the same 10GB/s connects to both Macs at its rated speed.
This behavious has persisted across OS updates since Big Sur.
My current thinking is that there's some undocumented quirks in place in MacOS that scales speeds down with certain USB controllers.
No, this isn't an example of Godwin's law being used as a tactic to end discussion; rather he was using hyperbole - a rhetorical device - to make a point. The slavery reference is not used to suggest that 'non-free software is morally equivalent to slavery/nazism' etc but rather is used as an example of a clear, strongly held moral position in order to emphasise the (possibly more subtle) original point. The point of hyperbole is to further elucidate, not close down.
This misunderstanding tends to be caused by (1) treating the rhetorical device literally rather than as an (intentionally exaggerated) analogy, and (2) - as in this case - by assuming that the argument being made is trying to draw some moral equivalence between the analogy and the original example. It isn't.
