Shor published multiple quantum algorithms, including one for discrete logarithms. The term is sometimes used interchangeably.

They're closely related, ECC and RSA are both instances of the hidden subgroup problem.

You can't, but given that it's a previously unsolved problem, it doesn't seem relevant? (nor are the author's potential biases - the claims are easily verified independently)

We tried this, but the quota for Opus models defaults to 0 on VertexAI and quota increase requests are auto-rejected.

Any tips?

No, unless you count tricks which are explicitly against ToS

They use a buffer battery, it's quite feasible with that.

You can still use OpenCode with the Anthropic API.

Fun fact: In Germany, the civil courts will usually take the case anyways if it has merit, but the winner ends up paying for the whole lawsuit if they failed to make an effort to resolve the case before suing.

And Hungary is pretty much a rogue EU state - their government did go full authoritarian and is aligned with Russia.

> But the implementation of Gerrit seems rather unloved

There are lots of people who are very fond of Gerrit, and if anything, upstream development has picked up recently. Google has an increasing amount of production code that lives outside of their monorepo, and all of those teams use Gerrit. They have a few internal plugins, but most improvements are released as part of the upstream project.

My company has been using it for years, it's a big and sustained productivity win once everyone is past the learning curve.

Gerritforge[0] offers commercial support and runs a very stable public instance, GerritHub. I'm not affiliated with them and not a customer, but I talk to them a lot on the Gerrit Discord server and they're awesome.

LLMs don't really know why they got something wrong, so unless it had access to the original chain of thought, it's just guessing.

It's really the same thing. Network partitions can (and do) occur within a single DC.

This sounds simple, but can only be achieved with high certainty using distributed consensus.

It's complex, but Ceph's storage and consensus layer is battle-tested and a much more solid foundation for serious use. Just make sure that your nodes don't run full!

Reliable networks don't actually exist[1].

Clearly, it's possible to reduce the risk to the point where many companies are willing to accept it, but it's still a problem and comes with high operational costs. And for some use cases (like finance), even a small risk of undefined database behavior or lost writes is unacceptable.

The future are distributed databases with consensus, and unfortunately, Postgres isn't there yet.

Postgres replication, even in synchronous mode, does not maintain its consistency guarantees during network partitions. It's not a CP system - I don't think it would actually pass a Jepsen test suite in a multi-node setup[1]. No amount of tooling can fix this without a consensus mechanism for transactions.

Same with MySQL and many other "traditional" databases. It tends to work out because these failures are rare and you can get pretty close with external leader election and fencing, but Postgres is NOT easy (likely impossible) to operate as a CP system according to the CAP theorem.

There are various attempts at fixing this (Yugabyte, Neon, Cockroach, TiDB, ...) which all come with various downsides.
