You can find random PDP, VAX, even X86 systems that have lifespans 20+ years. As for a single boot probably a much smaller corpus, maybe some forgotten Sun SPARC in a telco on -48V DC power bus.
A VAXCluster or Sysplex(S/390) would I guess be more analogous but those can be a bit Ship of Theseus since you can change the hardware out over time.
I'm referencing the premium you pay to get some paltry VM in a public cloud with bizarre storage and networking that primarily make sense for the market maker versus the actual cost of the hardware. There are ways to make cloud economics work as a user, but only where staffing costs would dwarf spend (i.e. small businesses) and I've never seen them in practice.
Wow. I can't imagine the thought process of going from accumulating a decade of Microsoft shares and experience during a pivotal era and deciding to plow it into a consumer scam op.
It's easier to see in hindsight but servers have eaten a lot of macro economic headwinds.
1999 and 2002 correspond roughly to telecom and dotcom bubbles popping. So open source operating systems were also pulled up into these positions through a lot of work and by the early 2000s it was kind of obvious this was the way forward.
2008 financial crisis really knocked the high end (RISC/UNIX/Itanium) and started the long migration to renting vs owning. In hindsight it's remarkable how much money used to just be there in the economy of all this. But I guess it still is, considering how expensive public cloud is.
Dell puts a fair amount of engineering into their servers (as do other main brands like HPE and Lenovo) so it's unfortunate they've lost their roots from the old mail order sales company.
If someone else is paying I'd prefer one of these big OEMs for established firmware lifecycle, spare parts and long gray market availability, shock (shipping) and thermodynamics engineering. If I'm paying, Asus or MiTAC (Tyan) are good enough.
AFAIK those sold relatively well, considering the TCO of both sides (NICs were very expensive and there were like a dozen companies vying for position once upon a time). They were also interesting because they were cut-through. CX4 was noticeably lower latency than SFP+. So a very fast, but feature limited architecture which is probably why other players like Cisco and then Arista (aka Broadcom) took over.
You can, to some degree, do an online defrag with zfs rewrite -P now although it is not the primary intent. The displayed fragementation may not go down or may even increase, but all the files will go through the allocation policy. zfs fragmentation display is a little misleading, it measures free space fragmentation.
ef_vi is a solarflare proprietary feature which is now a support product, AMD moved on to Pensando. Once you move away from busy poll, you rapidly lost grounds to use DPDK. The PMD is a deliberate design to elide latency and lower interconnect taxes like PCIe traffic and cache/memory bandwidth by batching queue maintenance, that is the bargain made with a PMD. The field opens to OS native fast paths which have fewer downsides outside of that niche. Application developers are rarely concerned with this because it's far from where the bottleneck is for them.. a web service is rarely primarily a data mover, while a proxy is. Tokio has more in common with Golang than something like DPDK.
I don't think there is a ton of overlap. tokio is appropriate for general userspace apps, ranging anywhere from a CLI, GUI, API or web app. DPDK and SPDK are specialized fast paths for building network data paths and storage solutions that come with tradeoffs: DPDK uses poll mode drivers, outside of the operating system, which have various implications including busy waiting and taking over the interface. That is why DPDK is fast, no kernel/userspace context switching and copies, and the drivers are tuned for the polling model. But it's not a general purpose building block.
Definitely an accomplished architect, there are a lot of fine construction details in these photos. So much that it makes the IT/low voltage installation look like a hack job.
Corporate IT is kind of a parallel universe to me, so it is interesting to see how widely used these products are and how impactful these types of events are.
There are a few broad categories to building one of these platforms.. core virtualization ("relatively easy"), device model ("medium hard"), storage management ("hard"), management plane ("medium hard").
VMWare popularized x86 core virtualization and defined their own device model because they were the early market leader. But the device model is pretty bizarre and I haven't been particularly impressed by the guest driver quality over the years. VMFS and vSAN seem good for storage, the latter being better than anything open source. Management plane was mediocre, I remember it took a while to move off Flash and fat clients while cloud vendors were showing none of that was necessary from inception, and everything is kind of in a walled garden by design (embedded DB etc).
Most of these things have large categories that are inherently disinflationary. You can't make a new authentic vintage Ferrari. Whether they are fungible is the main problem and case by case. But you generally don't do it to build wealth, it's an expression of it that happens to have yields if taken seriously.
Antiquities and heirlooms can be a good stable investment, the same reason people trade art or watches or guns or cars. Some of these are fun to use without reducing value.
I run a web to text usenet gateway and it has been an interesting challenge to scale it to deal with this. Article fetch and retrieval is extremely efficient but I apply JWZ threading and that can cause a single article to make a number of overview requests which are more expensive depending on the depth. I solve it currently with caching but will eventually implement a thread backend on the NNTP side to keep thread roots updated at insertion time and it will be a very cheap read request.
One persistent thought is what are people doing with this data? I get that people want to train models, but I also have a hard time believing there are more than a hundred companies with the resources to spider the web like this and actually do anything meaningful with all that data. Academics, researchers, and people working on lower level innovation are probably well off with CommonCrawl.. only people trying to make frontier models really need fresh and endless data right?
Wow this is a deep dive, most people focus on the PC era. The Ultima/Impression were some of the very first commercial PCI cards, behind maybe NCR SCSI. Another interesting vendor in that era was Number Nine.
Fluency in one's native language, what an achievement. Neither of these words are complicated. The treasury is unsalable bonds according to the thread, which means the US is in a financial collapse, but also has unlimited capacity to support someone's special interests abroad. Master logicians at work here.
The way it's written is ambiguous as it could also just mean the peak demand rate, not a capacity peak. I was doing some benchmarks for something recently and noticed how tricky it is to capture all the nuance of a test in prose.
"Looking up synonyms" huh? You have yet to make a coherent argument and keep trying to attack the messenger, typical behavior when people get called out for false entitlement. Your "psychopathy" accusations are pure cowardice.
Whatever point you are trying to make is not coming across, what even are these numbers and what do they have to do with citizenry of the United States? You also have a quantum view of the United States that it is and isn't impoverished, so it's supposed to liquidate to fund some other foreign entity that is not rate paying? I'm dizzy.
Expecting an onslaught of cash as some permanent way of being, especially given the fickleness (and fragility) of any state let alone political regime is an incredibly daft move. I don't care if it's Europe or Israel or Bangladesh, all this is ultimately graft that comes back to bite the people taxed and sent to wars to enable it. You make an adjacent comment that insinuates the US economy is basically bunk, which means the free lunch is over anyway.
Directly and indirectly, there are a lot of other knock on effects. Value objects (only recently being added) help. You could treat it similar to an HFT application, having ephemeral workers that don't do GC and dies on heap exhaustion, with a NIO coordinator that tries to avoid all garbage creation. But why at this point, square peg round hole.
I wouldn't consider Rust a manual memory environment. There are ways to do that at edges if needed, but it is otherwise very much automatic which is kind of the whole point of its design.
I haven't kept up with POWER after POWER9, but I recall it to be a true hardwired control RISC, pure as the driven snow. This had some interesting properties (along with other clever designs like eFuses and pNOR) for creating a really credible security posture. They do have a millicode system and chicken bits for oops moments (which are kind of an opposite risk, if you don't get those right for unexpected problems).
The conclusion is honest, and you can of course brute force any ISA into any role. I used to loathe x86 for that reason, but now that I'm older I respect the game.
