MySQL :: Hash join in MySQL 8
The build phase The literature usually divides hash join in two phases; the build phase and the probe phase. In the build phase, the server builds an in-memory hash table where rows from one of the inputs are stored, using the join attribute(s) as the hash table key. This input is also known as the build input, and let us assume that ‘countries’ is designated as the build input. Ideally, the serve
Podcasting Setup 2020
It’s been a while since the last time I wrote about my podcasting setup (link in Japanese). Although I haven’t changed most of the setup since the stability is one of the most important things, I’d like to note the current setup since it might be interesting to a future podcaster. Beta87A and US2x2 Recording Environment Before getting to the gears, it is important to pick where to record. The most

Load Balancing
Past a certain point, web applications outgrow a single server deployment. Companies either want to increase their availability, scalability, or both! To do this, they deploy their application across multiple servers with a load balancer in front to distribute incoming requests. Big companies may need thousands of servers running their web application to handle the load. In this post we're going t
I'm concerned by the number of times I've heard, "oh, we can do RAG with retriever X, here's the vector search query." Yes, your retriever for a RAG flow should definitely support vector search, since that will let you find documents with similar semantics to a user's query, but vector search is not enough. Your retriever should support a full hybrid search, meaning that it can perform both a vect

Now that our platforms are up and running as usual after yesterday’s outage, I thought it would be worth sharing a little more detail on what happened and why — and most importantly, how we’re learning from it. This outage was triggered by the system that manages our global backbone network capacity. The backbone is the network Facebook has built to connect all our computing facilities together, w
Summary of the Amazon Kinesis Event in the Northern Virginia (US-EAST-1) Region
November, 25th 2020 We wanted to provide you with some additional information about the service disruption that occurred in the Northern Virginia (US-EAST-1) Region on November 25th, 2020. Amazon Kinesis enables real-time processing of streaming data. In addition to its direct use by customers, Kinesis is used by several other AWS services. These services also saw impact during the event. The trig

(A lot of people over 30 or so, anyway. If this doesn’t sound familiar to you yet, just stick with me for a minute here.) At the time, I was happy with that. It seemed like
fast.ai - Mojo may be the biggest programming language advance in decades
I remember the first time I used the v1.0 of Visual Basic. Back then, it was a program for DOS. Before it, writing programs was extremely complex and I’d never managed to make much progress beyond the most basic toy applications. But with VB, I drew a button on the screen, typed in a single line of code that I wanted to run when that button was clicked, and I had a complete application I could now
Wiki - RustStarterKit2020
People were arguing about Rust’s std lib recently, so I went through the Cargo.toml of all the Rust projects I’ve written since 2015 and picked out the choice tools that get used over and over again. Up to date as of October 2020. Also see RustCrates, though that’s old. There’s also this, which is narrower but deeper, and awesome-rust, which is shallower and broader, and the various more specific
JavaScript is famous for the number of frameworks and tools that are created around it every week, and React, being one of the most popular of those frameworks as of late, “suffers” a similar fate, causing new developers to get overwhelmed when they attempt to start delving into the technology. So when it comes to picking the right IDE, the right visualizer or even the right stylesheet for your ne

How Netflix Scales its API with GraphQL Federation (Part 1)
Netflix is known for its loosely coupled and highly scalable microservice architecture. Independent services allow for evolving at different paces and scaling independently. Yet they add complexity for use cases that span multiple services. Rather than exposing 100s of microservices to UI developers, Netflix offers a unified API aggregation layer at the edge. UI developers love the simplicity of w

Learn how to bring multithreaded applications written in other languages to WebAssembly. WebAssembly threads support is one of the most important performance additions to WebAssembly. It allows you to either run parts of your code in parallel on separate cores, or the same code over independent parts of the input data, scaling it to as many cores as the user has and significantly reducing the over
One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m
They are popular and they are misunderstood. Containers have become the default way applications are packaged and run on servers, initially popularized by Docker. Now, Docker itself is misunderstood. It is the name of a company and a command (a suite of commands, rather) that allow you to manage containers (create, run, delete, network) easily. Containers themselves however, are created from a set
Bye, Amazon
May 1st was my last day as a VP and Distinguished Engineer at Amazon Web Services, after five years and five months of rewarding fun. I quit in dismay at Amazon firing whistleblowers who were making noise about warehouse employees frightened of Covid-19. What with big-tech salaries and share vestings, this will probably cost me over a million (pre-tax) dollars, not to mention the best job I’ve eve

With the recent launch of our Early Access preview of 1Password 8 on macOS I wanted to take a few minutes to pull back the curtain on this software development project that is over two years in the making.

How eBPF will solve Service Mesh - Goodbye Sidecars - Isovalent
Service mesh is a concept describing the requirements of modern cloud native applications with regards to communication, visibility, and security. Current implementations of this concept involve running sidecar proxies in each workload or pod. This is a pretty inefficient way of solving these requirements. In this post, we will look at an alternative to the sidecar model that provides a transparen

The ASR33, like most teletypes of the era, works at a fixed rate. It does 10 characters per second. It is 110 Baud, using 1 start, 8 data (inc parity), and 2 stop, so 10cps Tx and 10cps Rx; 10cps printing; 10cps punching tape; 10cps reading tape; 10cps maximum typing speed. Everything happens based on one motor that does this 10cps working, engaging clutches to start an operation which completes i

What is a B-tree?The B-tree plays a foundational role in many pieces of software, especially database management systems (DBMS). MySQL, Postgres, MongoDB, Dynamo, and many others rely on B-trees to perform efficient data lookups via indexes. By the time you finish this article, you'll have learned how B-trees and B+trees work, why databases use them for indexes, and why using a UUID as your primar

GNU Recutils
Fred and George, Turtles in love There are hundreds of cool command line tools that have been made over the years built on the unix philosophy. Plain text is powerful, ubiquitous, and human-centric. It was also the only option for computing for quite a while. It’s no surprise that some of the most sophisticated tools are focused on it. One such package is GNU Recutils, a set of tools and libraries
Hi, I'm Sam — software engineer at Spot and the 2nd most active maintainer of Emotion, a widely-popular CSS-in-JS library for React.

We'll start with an overview of CSS-in-JS and give an overview of its pros & cons. Then, we'll do a deep dive int

We’re going to put everything in a single file on disk again. As you might expect from our previous choice (and as many on the internet already predicted), we ran into some limits with etcd.

Earlier today, Airbnb Co-Founder and CEO Brian Chesky sent the following note to Airbnb employees. This is my seventh time talking to you from my house. Each time we’ve talked, I’ve shared good news and bad news, but today I have to share some very sad news. When you’ve asked me about layoffs, I’ve said that nothing is off the table. Today, I must confirm that we are reducing the size of the Airbn
Async Rust Is A Bad Language
But to get at whatever the hell I mean by that, we need to talk about why async Rust exists in the first place.
