Anybody with access to these models can challenge it to test the hypothesis that spacetime is a 4d viscous fluid with the speed of light being spacetime's sound barrier, mass relating to viscosity, blackholes being cavitation bubbles, Hawking radiation our perception of surface tension, and gravity just being a pressure differencial? Thanks

Beyond the training boundary. Seems a propos for "an infinite visual browser". I'm just not clear on how we get to the beyond part of it.

You can implement a BTree with nodes stored in file-backed memmaps. It's plenty fast for the usual business case.

I'll take this opportunity to remind anyone on Azure that if you enable service endpoints on a subnet without applying service endpoint policies, anyone with the resourceid of an affected subnet can silently backdoor your network. Your NSGs do not matter for service endpoints.

New comment by gxt in "Rust’s dependencies are starting to worry me"

gxt — Fri, 09 May 2025 14:22:12 +0000

You can audit your dependencies for crates with security vulnerabilities reported to the RustSec Advisory Database, also block unmaintained crates, and enforce your license requirements using SPDX expressions with cargo-audit and cargo-deny.

You can ensure that third-party Rust dependencies have been audited by a trusted entity with cargo-vet.

And you should have taken a look at where those 3M locs come from, it's usually from Microsoft's windows-rs crates that are transitively included in your dependencies through default features and build targets of crates built to run on windows.

Sure they are AGI. Just let one execute in while (1) and give it the ability to store and execute logic rag-like. Soon enough you're gonna have a pretty smart fellow chugging along.

At some point we should just commit the AST to git and render it however it is preferred in IDE.

New comment by gxt in "SQL nulls are weird"

gxt — Fri, 10 Jan 2025 03:55:00 +0000

This has always made queries unpredictable in many scenarios and it should be a feature to turn nulls off entirely and swap them out with Option instead.

gxt — Mon, 23 Dec 2024 14:58:04 +0000

I don't care about some scores going up. Newer models need to stop regressing on tasks they were already good at. 4o sucks at LLVM and related tasks were as legacy GPT 4 is relatively ok at it.

What if the DRM/license was based around offering binaries built with 8/16/32/64 bit limits in data types and max records per table, each being its own edition and priced accordingly? Eg yearly license of $8/160/3,200/640,000.

Ultimately security is incompatible with backwards compatibility. All OSes in prod today need to be rebuilt from the ground up to be secure for the next century. That means throwing out a lot of code too. It's the cost to pay.

New comment by gxt in "Writing an OS in Rust"

gxt — Sun, 15 Sep 2024 03:55:06 +0000

We shouldn't write an OS in rust. We should create a data platform on which we can run DML/DDL with an SSMS++ automatic frontend.

Is there an appliance or offline service to setup a private CA, do secure remote attestation, and issue certificates only to authenticated peers? Also preferably with fido2 support for administrative purposes.

New comment by gxt in "Belenios: Verifiable online voting system"

gxt — Tue, 06 Aug 2024 00:50:11 +0000

There is a contradiction on the first page. If "ballots are signed by the voter credential" then there is no vote privacy.

Electronic voting system must be prohibited across the board. Every system is vulnerable, electronic system are all remote controllable, I much prefer to have a person within the jurisdiction to go after than someone outside of it.

I don't understand howhy it's ever made out to be more complex than that.

Few can afford not to follow the basic (DO --> SECURE --> DOCUMENT --> ANNOUNCE) workflow. Working in any other order and you end up having to redo some if not most of the previous steps for whatever you where enterprising.

At these densities would it make sense to have raid arrays in SD form factor instead of just a bare device?
