Rebooting Petabyte Control Node

am rebooting one of the control nodes for a petabyte+ storage array, after 504 days of system uptime..

watching kernel log_level 6 debug info scroll by on the SoL terminal via iDrac..

logs scrolling, the array of SAS3 DE3-24C double-redundant SFF linked Oracle/Sun drive enclosures spin-up and begin talking to multipathd...

waiting for Zpool cache file import..

waiting.. 131 / 132 drives online across all enclosures.. hmm.. what's this now...

> transport_port_remove: removed: sas_addr(0x500c04f2cfe10620)

well ffs

> 12:0:10:0: SATA: handle(0x0017), sas_addr(0x500c04f2cfe10620), phy(32),

oh, that's a SATA drive on the system's local enclosure bay for scratch data, it's not part of the ZFS pool..

next step, not today, move control nodes to a higher performance + lower wattage pair of FreeBSD servers

terminal screen showing the storage node's system uptijme prior to a service / maintenance reboot. text shows 504 days of uptime with load average: 33.12, 32.96, 32.94

terminal screen showing a ZFS pool with many SAS3 drives in draid1, with dual optane nvme cache drives + dual deduplication drives and dual spare drives. top of screen shows a system log with some SAS related info from the kernel.

terminal screen showing kernel logs from SAS3 enclosure debugging, post-reboot stage

terminal screen showing the same ZFS pool, now having been imported after the node reboot cycle. scrub resilvered nice and quickly, no errors and all spares available.

Excellent Sunday afternoon read from Professor @drmichaellevin for Noema Magazine that takes a look at the metaphors we use to distinguish between organic and non-organic beings and challenges some of the assumptions around what we consider to be machines and/or living things.

Very much in the style of Donna Haraway, he advocates at once for #pragmatism, for empirically testing the methods we use for interrogating systems that imbricate the organic and the machine and to keep an open mind when categorising which is which.

For fans of Douglas Hofstadter, #cybernetics, #systems and #ConsequentialCategories.

@AmenZwa I'm puzzled that you don't mention Erlang. I'm not a programmer, but I follow the discussions. Maybe I'm completely out of date. I thought WhatsApp was built by 5 programmers in Erlang. Then completely rewritten when it was purchased by a large corp. Surely the importance of C in stability is due to the corporate infrastructure. I would have thought the brightest people would use the best new tools for prototyping and proof-of-concept for a new business, then sell it and move on. I'd hope that at least one Ukrainian group is using the Erlang infrastructure to program swarms of drones. I thought #Erlang was good for small and large #systems programming.

Coastal Environments - LiDAR Mapping of Copper Tailings Impacts, Particle Retention of Copper, Leaching, and Toxicity

maps - Geographic location of Grand (Big) Traverse Bay (red to green contours) along the eastern shoreline of the Keweenaw Peninsula. On the Peninsula, early copper mines are indicated by black dots within the Portage Lake Volcanic Series (dashed lines) and large stamp mills by stars. Two mills (Wolverine and Mohawk) are located near Gay. Insert shows anthropogenic copper inventory “halo” around the Peninsula, in µg/cm² copper

maps - Grand (Big) Traverse Bay: 2010 LiDAR DEM (digital elevation model) colour-coded by elevation and water depth (depth scale to right). Red horizontal contour lines are at 5 m depth intervals. Gay tailings pile (“original pile”) is indicated, as well as migrating underwater stamp sand bars dropping into an ancient river channel (the Trough; at locations #1, and #5). On the eastern flanks of Buffalo Reef, stamp sands are moving out of the Trough into cobble/boulder fields (#3, #4). Along the western edges, stamp sands have migrated as a beach deposit to the Traverse River Seawall (#8) and are slipping down into an underwater depression (#7) next to cobble/boulder fields. Stamp sands are also moving around the harbour outlet (#8). Hence, both the eastern and western sides of Buffalo Reef are experiencing tailings encroachment. Lower on the reef (#2, #6), there is little contamination. Past the Traverse River, the sands in the southern bay are almost exclusively natural quartz grains (#9), forming a white beach with shoreline cusp-like features and bar, plus ridges (#10) of natural sand moving from the shelf into deeper waters off the bay and into Lake Superior

aerial images - UAS high-resolution drone elevation and bathymetry surveys (base map 9 August 2022) of shoreline retreat at the original Gay pile location after bluff removal. Overlays along the beach edge trace shorelines in 2009, 2016, and 2022. The 78 m retreat over 6 years (2016–2022); equates to a 13 m/yr rate. The previous, nearly constant, long-term retreat rate prior to 2009 averaged 7.9 m/yr (ca. 26′) [7,57]. The original Jacobsville Sandstone shoreline, before stamp sands were discharged, is marked by the red border in the far-left upper region. Note white concrete basements of the two mills and remnants of both wooden and broken concrete launders in the northern region. Environmental recovery is beginning, as benthic organisms and fish are returning to clear underwater stretches of the bedrock shelf, where waves have removed stamp sands. Scattered trees (many birch) are beginning to colonise what is left of the original Gay Pile surface.

(b) Photo of 6–8 m high stamp sand bluffs in July 2008 off Gay, showing a buried small lateral sluiceway protruding out of the pile along the shoreline. Lake Superior waters are to the right; the dark beach sands are stamp sands with intermixed slime clay layers. (c) Bluff photo from about the same location in 2019, when shoreline erosion (ca. 7–8 m/year) reached the buried launder support beams, just before bluff removal.

There are two kinds of #systems #programming: small and large. By "small", I mean real-time control system, embedded software, or a device driver, the kind that people smarter and ballsier than I would happily write in hexadecimal. By "large", I mean operating system, communications protocol, compiler, database engine, and so on.

It is a fool's errand to design a new language that might replace C in the "small" space. For this type of software, assembly is too craggy, and C++ is too lumpy. Only Forth comes close to C, here.

And it is a herculean task to design a new language that might displace C++ in the "large" space. Countless new languages have tried, and only a few saw some success: Go and Rust, and perhaps Swift, Zig, Nim, and Odin.

This duopoly of the C family is both good and bad. This dominance is good, because it engenders stability. But stability in IT is an illusion. On the other hand, this dominance is bad, because it locks in the adopters and locks out the contenders. And there have been countless examples in IT of this lock-in/lock-out, duo-face problem, over the past 70 years.

What are the alternatives? Well, many arguments could be made in favour of every compiled language in existence. But the two simple choices are these:

• For the "small" space, there are plenty of cases where Forth is a good choice.
• For the "large" space, where safety and security are paramount, the ML family of languages—Standard ML, OCaml (including F# and Reason), and Rust—offer significant advantages over the C family.

Every modern compiled language is an admixture of the C and the ML families—like Rust. Yet, "new" languages keep cropping up, daily.

Despite some goon sending this kinda pricey Ice Lake Xeon through international post, wrapped up in two thin layers of non/anti-static bubble wrap shoved into a Tyvek shipping bag (not a box!), it arrived yesterday and seems to be in decent shape after a trip from Australia to the middle of America.

So, what one does with a NOS (new old stock) bit of hardware which needs to be perfect in order to function, we inspect with macro photos and various image filtering methods to identify any potential flaws.

I agree that while MMT presents as 'descriptive', to assume that human nature does not imbue descriptions with personally relevant meaning is to misunderstand human behavior.

It's actually quite simple to describe this without any judgement or subjective/political leanings. (It may be debated whether or not #systems philosophy is itself an ideology..)

The part where mmt shows taxes to be a dead-end in the financial flow, until spent back into the economy can be simplified/generalized further. Any system with flow will have the same set of logical parts that controls its physics. You need to know the volume that's moving, which includes both the velocity and size of the medium (like pipes & wires) it moves through the subsystems.

"Rich money" and "poor money" do not spend the same in an economy because of the important differences in their flows. Both taxes and profits inflate/increase the totals moving through the system, but to different areas. Profits flow up into the hands of the wealthy, and then 'trickle down' to the economy again (maybe, someday). It's very unidirectional, and most goes laterally to other wealthy nodes.

Taxing profits is *more* important than taxing incomes for this reason, otherwise, it's dead-end value for the system as a whole.
