Simple Writing pros & cons in Argdown is as simple as writing a Twitter message. You don't have to learn anything new, except a few simple rules that will feel very natural. Expressive With these simple rules you will be able to define more complex relations between arguments or dive into the details of their logical premise-conclusion structures. Powerful Argdown can even be used within Markdown!
Update: it looks this post has gotten way more attention than I anticipated. I’ve seen / received feedback that the title is misleading and some people get dissapointed. I see why, so at the risk of spoiling the surprise, let me clarify what this is about before starting.

The SaaS CTO Security Checklist Redux - Gold Fig — Peace of mind for infrastructure teams
Doing the basics goes a long way in keeping your company and product secure. This third1 edition of the SaaS CTO Security Checklist provides actionable security best practices CTOs (or anyone for that matter) can use to harden their security.

There are lots of posts trying to show how simple it is to get started with Kubernetes. But many of these posts use complicated Kubernetes jargon for that, so even those with some prior server-side knowledge might be bewildered. Let me try something different here. Instead of explaining one unfamiliar matter (how to run a web service in Kubernetes?) with another (you just need a manifest, with thr
It's Time to Forget About Docker | Martin Heinz | Personal Website & Blog
In the ancient times of containers (really more like 4 years ago) Docker was the only player in the container game. That's not the case anymore though and Docker is not the only, but rather just another container engine on the landscape. Docker allows us to build, run, pull, push or inspect container images, but for each of these tasks there are other alternative tools, which might just do better
I’ve been doing this “reliability” stuff for a little while now (~5 years), at companies ranging from about 20 developers to over 2,000. I’ve always cared primarily about the software elements I describe as living “outside” the application – like, how does it get its configuration? What kinds of instances does it run on, and are those the best kinds to use? What steps does it take on its path from
The Go Team 15 March 2022 Today the Go team is thrilled to release Go 1.18, which you can get by visiting the download page. Go 1.18 is a massive release that includes new features, performance improvements, and our biggest change ever to the language. It isn’t a stretch to say that the design for parts of Go 1.18 started over a decade ago when we first released Go. Generics In Go 1.18, we’re intr

How Japan Saved Tokyo's Rail Network from Collapse (Part 1, 1945-1982)
A train operator (or subway pusher?) holds onto rail as a window is busted open showing a packed train Imagine a city whose suburbs have outsized the core in a span of few years. Thanks to an economic boom and a severe housing crunch, residents are increasingly pushed to the outer ring of the city. Due to an influx to the outer areas, train services quickly become outstretched to its limits. Crowd
Visitor pattern in TypeScript Imagine that you are writing a program that can draw different shapes: circles, triangles, squares, etc. You represent them by corresponding data types. Depending on a language you use, these shapes become distinct classes, structs, members of an enum or parts of some algebraic data type. Because you also want to be able to do something with these shapes, you describe
Why LSP?
Why LSP? Apr 25, 2022 LSP (language server protocol) is fairly popular today. There’s a standard explanation of why that is the case. You probably have seen this picture before: I believe that this standard explanation of LSP popularity is wrong. In this post, I suggest an alternative picture. Standard Explanation The explanation goes like this: There are M editors and N languages. If you want to

Ox is lightweight so it can be used on older computers. Bear in mind, this is a personal project and is nowhere ne

GitHub - leandromoreira/cdn-up-and-running: CDN Up and Running - Building a CDN from Scratch to Learn about CDN
CDN Up and Running The objective of this repo is to build a body of knowledge on how CDNs work by coding one from "scratch". The CDN we're going to design uses: nginx, lua, docker, docker-compose, Prometheus, grafana, and wrk. We'll start creating a single backend service and expand from there to a multi-node, latency simulated, observable, and testable CDN. In each section, there are discussions
Optimize Cumulative Layout Shift Stay organized with collections Save and categorize content based on your preferences. Cumulative Layout Shift (CLS) is one of the three Core Web Vitals metrics.

Moonbit: the fast, compact & user friendly language for WebAssembly
The importance of WebAssembly (Wasm), a cross-platform Instruction Set Architecture (ISA), is escalating in Cloud and Edge computing, given its efficiency, security, compactness, and open standard. However, its true potential remains untapped. Low level Wasm languages like Rust and C/C++ are challenging to learn and can be slow for developers because of their long compilation time. On the other ha
I've found that one of the best ways to understand a new concept is to start from the very beginning. Start from a place where it doesn't exist yet and recreate it yourself, learning in the process not just how it works, but why it was designed the way it was. This isn't a practical guide to async, but hopefully some of the background knowledge it covers will help you think about asynchronous prob

Using unwrap() in Rust is Okay - Andrew Gallant's Blog
One day before Rust 1.0 was released, I published a blog post covering the fundamentals of error handling. A particularly important but small section buried in the middle of the article is named “unwrapping isn’t evil”. That section briefly described that, broadly speaking, using unwrap() is okay if it’s in test/example code or when panicking indicates a bug. I generally still hold that belief tod
Two years ago more or less I started my journey in Linux. I was scared at first and I didn’t know where to start from. But then I decided to buy a book - and what a book! - in order to follow a path. Along the way, I integrated the material with up-to-date documentation from kernel.org and source code. In the meantime, I started to learn C a bit so that I also could have played with what I was lea
Async Ruby - Bruno Sutic
Ruby has an Async implementation! It's available today, it's production-ready, and it's probably the most awesome thing that's happened to Ruby in the last decade, if not longer. Async Ruby adds new concurrency features to the language; you can think of it as "threads with none of the downsides". It's been in the making for a couple of years, and with Ruby 3.0, it's finally ready for prime time. I
The (not so) hidden cost of sharing code between iOS and Android
The (not so) hidden cost of sharing code between iOS and Android Until very recently, Dropbox had a technical strategy on mobile of sharing code between iOS and Android via C++. The idea behind this strategy was simple—write the code once in C++ instead of twice in Java and Objective C. We adopted this C++ strategy back in 2013, when our mobile engineering team was relatively small and needed to s

Let's build a Full-Text Search engine - Artem Krylysov
Full-Text Search is one of those tools people use every day without realizing it. If you ever googled "golang coverage report" or tried to find "indoor wireless camera" on an e-commerce website, you used some kind of full-text search. Full-Text Search (FTS) is a technique for searching text in a collection of documents. A document can refer to a web page, a newspaper article, an email message, or
