Additional time axes allow you to separate transactions from different sources of input. E.g. in a collaborative system it could be helpful to ask questions while rewinding the actions of a particular user. But a different question is wheth

If model-theoretic semantics and the various ways to slice, dice, and extend Datalog are interesting to you, then almost any talk by Peter Alvaro might be as well. In particular: https://www.youtube.com/watch?v=R2Aa4PivG0g

Check out the white paper at https://github.com/ipfs/papers/raw/master/ipfs-cap2pfs/ipfs-... , section 3.7. There is a name system called IPNS.

I think Finda ( https://keminglabs.com/finda/ ) fills a similar need, runs offline, and indexes lots of other stuff as well. Although I think it is not possible to assign additional keywords. (Not affiliated in any way,

Interesting point. As I don't have much experience in this area: Can you elaborate on some use cases for layouts other than AoS and SoA?

by ComNik 9y ago
Jonathan Blow's language "jai" allows for seamlessly switching between AoS and SoA and generally seems to value efficient data layout and "gradual" optimization over safety (in contrast to e.g. Rust). Unfortunately,

For anyone interested in exploring the datomic model, there is a great ClojureScript in-memory implementation called datascript ( https://github.com/tonsky/datascript ) by Nikita Prokopov.

We use Datalog every day in a React-Native application, via the datascript db ( https://github.com/tonsky/datascript ). Has been a very positive experience so far. Thinking in "facts" / binary relations is

Thank you for Murmur3! I have been using it in a consistent hashing implementation as part of my bachelor's thesis and it is performing very well.

Interesting note, thank you. Are you referring to "Sigma" https://code.facebook.com/posts/745068642270222/fighting-spa... ?

That was not the intension behind my comment at all. I rely on type systems a lot, myself. I was trying to note that Clojure, as a dynamic language, is making a (to my eyes) very interesting choice, of doubling down on these dynamic methods

As a side note in his talk "Simple Made Easy" ( https://www.infoq.com/presentations/Simple-Made-Easy , around minute 42) Rich Hickey mentions, that conditional statements are complex, because they spread (busin

Full, formal verification of complex systems (especially in the distributed case) requires a lot of modelling effort, beyond what is needed for "mere" implementation. A lot of important constraints cannot even be expressed in most

You make a very good point, the comparison was flawed there. > The thing I do see as being important is not how you write these things down, but whether they have an accessible representation at run/read/compile/whenever t

Clojure, with its dabbling in schemas and rule systems / logic programming (as a substitute for conditional statements) and thanks to its great tools (like figwheel or devcards), could really be establishing a cheaper, "as-good&qu

Can't comment on DarkBasic or Monkey, but: BlitzBasic and BlitzMax are about the same language. What BlitzMax provided over BlitzBasic was a direct integration with DirectX and OpenGL, which allowed you to make 2D games with hardware s

I spent most of my early programming years with BlitzMax. The language itself probably has no future on it's own, but combined with the DX/OpenGL integration and overall straightforwardness, I'd heavily recommend it for inter

It means that operations don't get executed in the same order on every replica. If the systems state depends on the ordering of operations, then each replica might be in a different state for the same set of operations. "Consisten

For all application-data events I consider postgres to be the ground-truth. That is somewhat unfortunate, because one can't easily place a queue in front of the database. For metrics and logs, the Kafka topic itself (which is persisted

Yes, I fully recognize the problem with double-writing. I will definitely try out Bottled Water. I was also thinking about replacing Kafka with a much simpler, lower-throughput system (because we are lightyears from LinkedIn's requirem

Thank you for your detailed thoughts. You obviously have much more practical experience with this kind of system. Many of the problems you mentioned I am aware of, and also have no workable solution yet (detecting lost messages being the bi
