> I can't find any other open source time series database except Mimir/Cortex which allows this much scale (clustering options in their open source version)

The following open source time series databases also can scale horizontally to many nodes:

- Thanos - https://github.com/thanos-io/thanos/

- M3 - https://github.com/m3db/m3

- Cluster version of VictoriaMetrics - https://docs.victoriametrics.com/Cluster-VictoriaMetrics.htm... (I'm CTO at VictoriaMetrics)

> Can we use Prometheus/Mimir as general purpose time series database?

This depends on what do you mean under "general purpose time series database". Prometheus/Mimir are optimized for storing (timestamp, value) series where timestamp is a unix timestamp in milliseconds and value is a floating-point number. Each series has a name and can have arbitrary set of additional (label=value) labels. Prometheus/Mimir aren't optimized for storing and processing series of other value types such as strings (aka logs) and complex datastructures (aka events and traces).

So, if you need storing time series with floating-point values, then Prometheus/Mimir may be a good fit. Otherwise take a look at ClickHouse [1] - it can efficiently store and process time series with values of arbitrary types.

PCA can be construed as a loss compression of the data matrix. In fact, Eckart-Young theorem shows that this is an optimal compression (optimal w.r.t low rank, i.e. space to hold the values). In the language of OP, this shows the minimal energy loss for a given space constraint.

The key word is "lossy". It may as well be that the loss'ed part had the signal for further classification down the pipeline. Or may be not. It depends on the case.

I'm not sure what you mean by reading.

We say that we can experience thinking about an Apple, or imagining an Apple. I see no reason why a computer, or other physically implemented AGI system, could not do that. I suspect the act of imagination is just generating, processing and transforming a computational model abstracting the thing being imagined.

I believe brains are physical objects, so therefore physical objects can imagine Apples.

Not necessarily. Ubuntu LTS kernel is often very far behind and you have to rely on Canonical to backport drivers for you.

e.g. Vulkan on my 5700 XT didn't work (despite AMD being very good at writing kernel drivers!) because the Ubuntu kernel was so far behind. Switching to an up-to-date vanilla kernel and all my problems went away...

The reason I buy on Amazon is that finding anything you wouldn't see in a typical department store from somewhere else online takes a bit of effort; and it's an additional effort to gain some confidence that the "somewhere else" won't scam me, sign me up for even more spam, etc.

If there were some reliable meta-shopping site that aggregated trustworthy vendors, I would use that--but I can't see how to build one that wouldn't have all the problems of Amazon in the best case; and all the problems of wish.com in the more likely case.

[1] is a typical sign in Britain. The green sign (hopefully in my link) shows the main destinations, e.g. Warwick, since this is a long distance road. The white sign 200m further along the road shows more local destinations.

There are then large signs at every exit on the roundabout.

Sometimes (not here) the approach lanes have giant letters/numbers painted in each lane, even if it's crushed so Warwick is written "Wa'ck" or something.

Nothing prevents you going around a second time if you need to. Your satnav will have said something like "In 500m, at the roundabout, take the second exit to Warwick" and then "Take the second exit to Warwick".

On this road (which is typical) there's the confirmation-of-route sign very soon after exiting the roundabout towards Warwick, or (third exit) to the village.

> you can just go around again if you aren't sure which exit you need; you are forced into taking an exit, right or wrong

...doesn't make sense?

> the radius is too small so there is not much time to make a complex decision, especially if you aren't already familiar with the exits

Ideally, you should know what exit you need from the signs you saw approaching the roundabout. If not, slow down and go around again.

> it's hard to monitor traffic entering the roundabout to make sure I don't get hit by someone having a harder time navigating this than me, while at the same time trying to figure out what the crazy sign diagrams mean.

This is why the signs were 100-200m before the roundabout. It sounds like you are approaching the roundabout too fast.

We should (but the C++ committee too often does not) distinguish between additional complexity to serve some particular purpose, and constant greenfield development done solely because it was easier to burn some more forest than deal with the mess left by the previous occupants when renovating. This latter practice is of course unsustainable.

It is also good to distinguish complexity which matters to the implementer (for C++ this may represent maybe three groups - LLVM, GNU and MS - all of which have committee members) versus that which matters to ordinary programmers.

The novice Rust programmer in 2022 sees only that arrays work as you would expect -- the apparent complexity is quite small. You can't grow or shrink them (use a Vec) but you can mutate them (if you asked for a mutable array), you can iterate over them like other containers, they have the affordances you'd expect from a slice type (e.g. you can sort them, and if they're sorted you can do binary searches, that sort of thing) and so on.

In fact arranging this was pretty complicated, const Generics are involved for example, which Rust 1.0 did not have. But this novice programmer needn't care why arrays work, they just do, it's very simple. Compare the C++ novice who will be told that only some array features work, and they're not a collection, and they also aren't really a slice, and the affordances you'd want are missing, the C++ novice must carry around a pretty complicated understanding, all in order to simplify implementation for a handful of people.

Rust also has a third distinction of complexity, where it matters whether the complexity is exposed in safe Rust. For C++ the pointer provenance problem affects everybody. Finally resolving this long-standing hole in the C++ standard would significantly increase complexity for the language, and every C++ programmer may be at risk from the consequences. In contrast, safe Rust programmers needn't even be aware that provenance is a thing, only the nomicon explains that of course pointers aren't really just addresses because only in unsafe is management of provenance your problem.

This is false though as your top eigenvectors are going to have non-zero entries in all components unless your original data has some features with 0 covariance which is highly unlikely. You still need to collect all the original features, you have not selected features that can be removed.

I submit that any attempt to reduce your humanity to a math problem is ultimately going to give perverse results. Why give money to children in foreign countries and save 10,000 lives when I can contribute to the creation of technology that could save the lives of countless future human beings? Instead of that, why not give my money to Elon to help ensure we eventually develop an extraterrestrial and (possibly even extrasolar) colonization capability which will help ensure the survival of humanity as a whole? Oh, I know, I'll build a company that exploits its workers and consumers in order to amass a fortune that I can ultimately use to further that goal!

The part of your mind that does this kind of logic or math based reasoning is very useful, but there's a reason our minds aren't entirely rational. Rationality is a tool we use, it is not us and it is not the end-all be-all way of understanding and interacting with our reality.

I'd have to dig out the documentation, but I think Tilera addressed some of the Transputer's link limitations by having five (and six in the TilePro64) separate communications meshes between the cores.

There's one mesh each for: memory access, packet transfers, user data network, cache misses, and IPC. The Pro added a cache coherency mesh too.

Sadly, Tilera was bought by EZChip, who were bought by Mellanox, who were bought by NVIDIA, and the Tilera processors don't seem to be available or being updated.

However, AIUI, the Serenity kernel isn't C++ but C. I could be wrong.

As such, as this was specifically a piece about non-C OSes, I felt it didn't really fit.

Secondly, although now I've had a bit of exposure to it writing that 2nd article, nonetheless, SerenityOS -- impressive as it is -- remains a bit of a prototype sort of project, rather than anything actually deployed in production anywhere. The project pages note that there are issues getting it to run anywhere outside of QEMU.

Whereas, say, Oberon is pretty obscure, but various versions of Oberon run on bare metal, or as VMs under multiple other OSes, or both, and ETH very much ran Oberon in production on bare metal for non-technical staff for years. There are 3-4 different dialects of Oberon, it runs natively on other OSes, it has OSes designed solely to be VMs, and so on.

To draw a comparison: it straddles the spaces of Plan 9 (mainly intended as a native bare-metal OS) to Taos (primarily bare-metal but deeply cross-platform, no native binaries as such) to Inferno (deeply cross-platform, no native binaries as such, but mainly intended to run under other OSes).

Whereas in the space of, say, Rust OSes, there are so few that even niche ones that are in prototype stage are worthy of mention... IMHO.

I'll just pile on here. The functionality of the Terminal is seemingly infinite and goes way beyond market data. Although it is obviously very good at market data. You pull up a bond, or future, or stock, or index, type FLDS and see an amazing amount of data beyond just the price.

It has maps (ships, refineries, fires, earthquakes, etc), flight schedules, overviews, top/bottom lists, correlations, regressions... ad nauseam. And also a quant platform, where you can code in Python I think, but I've never used it. I've been using for longer than I can remember and it's still impressive.

Also, they have generally a good to excellent help desk. Hit F1 twice and you're chatting to a real person, who can either help you or direct you to someone else who can. They have let me down on occasion too, but compared to other help desks/support, BB is the best.

I am starting to see more latency in pulling up functions in the Terminal, so I hope they're not losing sight of the UX. Near-instance response used to be commonplace, now I find that even some very common screens like WEI take noticeable time to load.

It is expensive. Many competitors have come and gone, and the closest thing now is I think Eikon, which also have installed to access the old Datastream data, and it's a complex monstrosity. FactSet is another one but I haven't used it in a long time. Every time cost-cutting time comes, one of the first questions is, "Do you really need Bloomberg?" Well, yes, I do.

Also don't forget about how deeply integrated BB is at many companies. Not just spreadsheets, but entire applications using the API.

So good luck, but I don't see it happening.

All of these tools will at least run an introspection query to get the available tables and columns to display the data. But these queries will fail because SQLite doesn't have these tables.

You wrote in the previous comment:

> ... so external systems (eg Prometheus) can read data from them easily.

I pointed to an issue, which prevents from practical usage of remote read protocol from Prometheus itself.

As for the interoperability with external systems, Prometheus querying API [1] is better suited for this task than Prometheus remote read protocol because of the following reasons:

- Prometheus querying API is easy to use, since it is just JSON over HTTP (unlike compressed protobuf used for Prometheus remote read). E.g. humans can test and debug it either directly in web-browser or in a command-line shell with curl.

- Prometheus querying API is already supported by popular external systems such as Grafana.

- Many Prometheus-compatible systems such as Thanos, Cortex, M3, VictoriaMetrics, etc. support Prometheus querying API out of the box.

Avalanche is likeliest explanation for tragic Dyatlov Pass incident
About 8 years ago our Bloomberg rep met with us and told us that our use of Bloomberg Data License that we use to load descriptives into our trading platform was going to essentially have a crippling price increase.

They were going to be nice about it though and enact the crippling price increase over four years in equal installments. We were haughtily told there was no negotiation.

About 2.5 years later I emailed my rep and asked, “What is our minimum spend?” and he replied $1,000 per month.

I then switched to another provider. The data was better, perfectly mapped to our trading platform and required almost no work on our part. It was less than 1/4 the price even before Bloomberg’s crippling price increase went fully into effect.

It took my Bloomberg rep three months to notice we were down to paying our giant reduction of $1,000 per month. He sent me begging emails asking to meet, called me daily, asked why I didn’t tell him so he could negotiate. I didn’t reply to a single thing. Then he started calling and emailing my boss. Who didn’t reply.

I agree - competing with Bloomberg Terminals is going to be very hard. But there are so many people (like me) that literally hate Bloomberg the company and will actively ferret them out of any organization we move to because there are alternatives to Bloomberg products that are actually better in some areas.
sure transformer models may not be intelligence as people often claim, but undeniably ML has been conquering all the sensory modalities one after another. And the human brain itself is mostly devoted to sensory processing. It is conceivable that the remaining part of the puzzle of intelligence is not far out of grasp yet. While intelligence may seem undefined and elusive, it will probably turn out to be less complex than we think it is (if we are to take a hint from biology )
