EACL can efficiently answer questions like:

- "Does have on ?" via `eacl/can?` or `eacl/check-permission`

- "Which does have for?" via `eacl/lookup-resources`

- "Which have on ?" via `eacl/lookup-subjects`

EACL supports four Consistency Modes that map to SpiceDB's consistency semantics, so you can run these queries against the database as-of now, or via `at-least-as-fresh` semantics for better cache reuse.

SpiceDB is the most faithful open-source implementation of Google Zanzibar, and is used OpenAI, Reddit and Netflix. Zanzibar powers Google Drive, YouTube, Gmail and Google Calendar, serving billions of authorization requests per day over billions of Relationships.

"Situated" here means that permission data co-exist with your application data. This has several advantages over external AuthZ:

- Reduced network latency (no network hop to external system),

- Strong local consistency,

- Scale reads by scaling Peers horizontally, and

- Real-time UI view maintenance – tail the tx-log and run `eacl/lookup-subjects` for changed permissioned entities and notify online users of novelty, instead of polling or re-querying for all online users.

Rationale:

I spent the better half of 2024 integrating with SpiceDB at a former employer. SpiceDB is great, but it becomes non-trivial to keep an external authorization system in-sync, especially when there is an impedance mismatch between your data and SpiceDB’s 3-tuple Relationship schema. Plus, you also have to deal with eventual consistency.

So, you change your data model to match the Spice schema to make syncing easier. Now you can tail the transactor log via `d/listener` and write Relationship changes 1-for-1.

But once you do that, you might as well run your permission queries in your application and then you have one less system to deal with...and this is exactly what EACL does. You still retain the option to migrate to SpiceDB later.

EACL is aimed at a different scale from SpiceDB: Spice is benchmarked against 100B Relationships. EACL aims for ~1-100M Relationships in a situated environment, but there is no reason it won't scale further if you scale out Peers.

EACL is open-source under EPL 2.0.

"Situated" here means that permissions are just data that co-exist with your application data. This has several advantages: reduced network latency, strong local consistency and opportunities for real-time view maintenance.

So, for anyone thinking of using Ketamine on the regular or even monthly, there is good evidence that EGCG (epigallocatechin gallate) administered 30 minutes before prevents KBS (Ketamine Bladder Syndrome), in rats: https://www.sciencedirect.com/science/article/pii/S187952261...

This promising rat study from 2015 shows that EGCG extracted from green tea has a protective effect on the bladder, reversing ketamine-induced damage to control levels. So if you are taking ketamine for major depression or recreationally, taking EGCG before may prevent long-term bladder damage.

Summary from the study:

# Objective

To investigate the protective effect of green tea epigallocatechin gallate (EGCG) on long-term ketamine-induced ulcerative cystitis (KIC) using a ketamine addiction rat model.

# Materials and methods

Thirty Sprague-Dawley rats were divided into three groups which received saline, ketamine (25 mg/kg/d), or ketamine combined with EGCG (10 μM/kg) for a period of 28 days. In each group, cystometry and a metabolic cage micturition pattern study were performed weekly. Masson's trichrome study was done to evaluate the morphologic changes. Western blot analyses were carried out to examine the expressions of inflammatory protein [transforming growth factor-β (TGF-β)] and fibrosis proteins (fibronectin and type I collagen) in bladder tissues.

# Results

Chronic ketamine treatment resulted in bladder hyperactivity with a significant increase in micturition frequency and a decrease in bladder compliance. These alterations in micturition pattern were accompanied by increases in the expressions of inflammatory and fibrosis markers, TGF-β, fibronectin, and type I collagen after long-term ketamine treatment. Masson's trichrome stain showed that ketamine treatment decreased urothelium thickness while increasing the collagen to smooth muscle ratio and exacerbating interstitial fibrosis. By contrast, simultaneous EGCG and ketamine treatment reversed ketamine-induced damage to almost control levels, showing the protective effect of EGCG.

tldr; Starlink doesn't work in South Africa, Elon's home country, because the ANC and its lawfare arm ICASA demands they hand over 30% to the State because of BEE laws.
