Insightful talk, I would love to see better alternatives to JWT become common. However server side sessions still seem like a solid alternative, with far fewer problems/attack surface than any of the signed token approaches discussed.

Fastly have done some fantastic work in this area, it's great to hear about it! I would like to warn about putting more than one capability into a credential. Once you do this, the lovely mathematical properties that object-capability systems grant you don't entirely hold, even if the weakness is nicely scoped. Being able to re-use one credential for a different resource is at the root of a wide variety of vulnerabilities, especially attacks involving enumeration or ibac.

Isn’t the fact that he has a black card authorization and not authentication?

yes but can i test a sum function with this thing? lol

You have to look into meta data checksums in ZFS as it enables bitrot correction. Unlike Linux, Solaris and later BSD added ZFS exactly because of oblivious data loss caused by bitrot. And get this, ZFS was introduced with Solaris 10 a full decade before Fsyncgate… While you can’t easily update the IO used in a database, you can install a BSD distribution and format your database storage disk array with ZFS for handling all mission critical data. An enterprise would probably go with Oracle DB on Solaris . That said, for financial data, TigerBeetle is currently the single best option because not everyone has the time and expertise to gronk BSD / ZFS or the money for Oracle on Solaris.

You're Telling Me: Database Scaling - Because You Want Me to Believe its Cheap to Transmit Data on your Networks. I can come To America. build a Website in My Garage. Steal somethings from your Basement and Have a Successful E-Commerce Web Store. So You're Telling Me Database Scaling: "Come explore lessons learned from 5 years of building databases at petabyte scale at Dropbox and Figma" - You Want Me To Come for an Education at Dropbox/Figma. Where You'll Teach a Pr0stitute of Yours to Fu*ck Me.

You're Telling Me: Database Scaling - To Hide or Prevent Me from Learning - How You've Built Your Satellite Broadband Networks.

The Problem isnt Database Scaling. You Simply Shard the Database. Shard Means Split Up. Customers With surnames Beginning With A, are On Database 1. Customers With surnames Beginning With B are On Database 2. you Can Shard at The App Layer: PHP or ASP or You Can shard at The Database Layer: PGPool (Proxy DB). The Difficulty is Building The Network. You Have To Pay to Transmit Data on somebody else's Network. You've Turned Thailand into Slums to Make Your Satellite Broadband Networks. You Need Lots of Kerosine for your Top Gun Airforce (Jet engines) - You've Got Lots of Petrol/Diesel for Electricity And Piston Engine Aircraft. Such as a Cessna C172 or a Diamond DA42. Your Satellites are in The Clouds: Between 6,000 and 10,000 Feet. Piston Diesel Engines Work at that Altitude. You Need Kerosine for 15,000 Feet and above Jet Engines. The Difficulty is Building The Network. You Have To Pay to Transmit Data on somebody else's Network. You've Turned Thailand into Slums to Make Your Satellite Broadband Networks.

rad Intro ;)

Trying to abstract the client/server communication is a tale as old as MS ASP. It was leaky then, and it is leaky now. Much nicer to be explicit, and have to decide how to deal with network partition.

Dang, I want to hear so much more about voxel data storage, what a great talk! Also I love Loris's HTML LSP; I'm already using it.

juicy talks

Ghostty ❤

I love love love zig fmt's (zls') formatting rules for trailing commas resulting in each element on a new line. It's amazing. I get really frustrated everywhere else where this is not the default behavior of the formatter. Glad to see it coming to HTML :) Thanks loris!

nice, high info density talk, very cool project

Hi

I enjoy Matklad's fluent code navigation and editing skills. Considering his deep knowledge in how to make IDE smart (LSP and rust-analyzer fame), I wish for special episode on his development setup, and effective use of VS Code for Zig programming and TigerBeetle.

Every video I watch by this hero is amazing. Your contributions are invaluable.

Well at least it works for its users

Go slow to go fast. Love it!

This is all true for transactional workloads

Big distributed systems are all about trade offs. I personally would not want to use PostgreSQL for such an in-house build, but if it makes sense, it makes sense. For this product, with these constraints, on this timeline, they did what was best for the product. Which is the way it should always be, but it often is not. Congratulations for a job well done! ♥️

Amazing

Does anyone have link to a "great talk about NES our CEO gave last year" at 10:35?

This video condenses 100s of arcane PhD research papers into a clear, concise, and entertaining 45-minute presentation any high schooler could understand. Unbelievable!

10:59 I think SQL being a *query* language, it is maybe unfair to start off judging it with “hard to express application *behavior*”. It’s like judging a cake for not being savory. The fact that so many have been abusing SQL, which is designed to query for current time snapshot, to write time-varying behavior instead, is a testament to how good an abstraction it is at querying that it forces systems around it to conform to its shape.

great talk. love the philosophy behind tigerbeetle. just awesome. you guys are killing it!

A database is a base for your data. It is in the name!

RE: Andy Pavlo Carnegie Mellon University has an _excellent_ freely available database course, presented by Andy BTW. "CMU Intro to Database Systems", here on YT.

Current Relational Databases also completely ignore the concept of a sharable Domain; some DBs have them, but nobody is using them or teaching them either. For simplicity's sake think of a Domain as a datatype with extra constraints (either a subselection of specific values, or perhaps a range), that can be shared between columns (Column A from table X can have the same domain as column B from table Y).

SQL is indeed a terrible language. I hope that in the next Stack Overflow Survey they'll introduce a separate "Query Language" question, instead of slapping SQL between regular programming languages. BTW, it's terrible because a Relational Query Language should ALWAYS return a Relation (a set of tuples), but SQL can return a table, a row, a column or a cell, which is kind of awful.

I can't have you disrespecting The Coddfather (E. F. Codd) like that! The Relational Model was invented in 1969 (nice!) in a paper called "Derivability, Redundancy, and Consistency of Relations Stored in Large Data Banks", and took off in the second paper called "A Relational Model of Data for Large Shared Data Banks" in 1970. He also designed ALPHA in his paper "ALPHA: A Data Base Sublanguage Founded on the Relational Calculus", an unimplemented language that was based on Relational Calculus that could've been used to query data, instead of SQL, but alas. Oracle took SQL as basis and IBM had to follow suit if not to lose market share to Oracle, as the Relational Model was VASTLY superior to existing data types (trees and networks) that were being abused as databases - they were not even official models yet - The Relational Model predates whatever models IMS and IDS later on generated. There. Now I'm much more content.

I worked at a company that uses Infor SyteLine ERP and the DBA was constantly complaining about all the long-running transactions it used and the issues they caused on SQL Server.

Datalog is a fantastic query language.

Git is a example of terrible abstractions.

this truly conveys that idea that databases are literally just shared space.

The intro theme doesn't need to go this hard

Chimera Linux mentioned!

well, data is always immutable, what it is mutable is rw storage

I wanna know if the Roc team will ever make a JavaScript platform or will Richard always say "Use Elm"

well, 8:25 thats obvious because when you parallelize you are adding communication problem, however, the reason you add concurrency is to get fault-tolerance and high availability.

Great talk, great technique, great philosophy behind these techniques. Cheers to many more of these!

Not sure this is the same guy almost took down mongodb & elastic pointing out data inconsistencies in write operations a decade ago

Lesssssgo

waitingggg for this one

great talk, thank you very much

Commutativity is not the important factor for the reduce function; assiciativity is.

Love the mixture of fun and useful info in Andrews talks
