Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

A traditional table-based DFA implementation looks like this:

uint8_t table[NUM_STATES][256]

uint8_t run(const uint8_t *start, const uint8_t *end, uint8_t state) {
    for (const uint8_t *s = start; s != end; s++)
        state = table[state][*s];
    return state;
}

API Design: Builder APIs (October-2020)

Some time has past (three years!) since I last wrote about API specifically about coroutines style APIs so I thought why not write another one about a different API type I encounter relatively often. The builder API.

Now first let me take a step back and put this into 20,000 feet view on where builder APIs are located in the grant scheme. In general everything in computing is separated into input, processing and finally output. In its most basic form I am currently typing on my keyboard. All pressed keys are processed from the OS up to the browser I am writing this in and finally rendered and displayed on the screen as output. Of course this example is very user centric

Information in this Gist originally from this github issue, which is outdated.

As @RomanMinkin mentioned, you can also consider Casbin (https://github.com/casbin/casbin). It is the most starred authorization library in Golang. There are several differences between Casbin and OPA.

Feature	Casbin	OPA
Library or service?	Library/Service	Library/Service
How to write policy?	Two parts: model and policy. Model is general authorization logic. Policy is concrete policy rule.	A single part: Rego
RBAC hierarchy	Casbin supports role hierarchy (a role can have a sub-role)	Role hierarchies can be encoded in data. Also with the new graph.reachable() built-in function queries over those hierarchies are much more feasible now.
RBAC separation of duties	Not supported	Supported: two roles cannot be assigned together
