Discover Graft, an open-source transactional storage engine built to solve the challenges of syncing data at the edge. Inspired by lessons from SQLSync, Graft enables lazy, partial, and strongly consistent replication—allowing edge applications to sync only the data they need, exactly when they need it.

The Godbolt Compiler Explorer is a fantastic tool for assembler programmers. In this post, I show you how to use Compiler Explorer to generate RISC-V assembly code and offer some ideas to make best use of this tool.

Over the last many years, de-facto language of the Web (specifically front-end) has been Javascript (and variants like Typescript, ECMAScript versions and so on). The Web development has been revolving around HTML+CSS+Javascript trio. It all started with support for Javascript in browsers, followed by addition of XMLHTTP API, Rich DOM Manipulation Support in Javascript. To induce order and apply patterns to Javascript’s usage in browsers, numerous frameworks and libraries were introduced like React and Vue among others. To begin with, The target used to be browsers on Large Devices like Desktop & Laptops. However, soon all sorts of devices were targetted with advent of Responsive and Progressive CSS+Javascript libraries eg. Bootstrap. Offline Support soon came in ref: Electron and Progressive Web Applications.

We're open sourcing postgres-wasm, a PostgresQL server that runs inside a browser, with our friends at Snaplet.

It has been six years since we published our interview with Riccardo Mottola, one of the pillars of software development for our favorite architecture. In it, we talked about the vital importance of having an up-to-date browser to make a PowerPC computer usable in the modern world. At that time, we were anticipating the release […]

Thursday at the Open Source Summit started as usual at the keynotes.\nRobin Bender Ginn opened today’s session with a brief introduction and then we jumped into the first session by Matt Butcher of Fermyon.\nI’ve enjoyed these keynotes so far, but to be honest nothing has made me go “wow!” as much as this presentation by Fermyon. I felt like I was witnessing a paradigm shift in the way we provide services over the network.\n

In this, my fifth article on the Go programming language, I’m looking at the build and packaging process, and other tooling. I’ll start by looking at how code is structured into packages, and then look at the tools for building, packaging and testing.

For the last two years, I have been trying to improve CRuby performance. I have been working simultaneously on two major fronts: introducing register transfer language (RTL) for the CRuby virtual machine (VM) and just-in-time (JIT) compilation. For background on the goal of having Ruby 3 be 3 times faster than version 2 (3X3), see my previous article, “Towards the Ruby 3x3 Performance Goal”.

Narrow waists: an idea in software architecture that relates to networking, operating systems, language design, compilers, and distributed systems.

In this challenge, we had to obtain remote code execution, simply by exploiting a 1-day bug that forgot the difference between -0 and +0. This has probably been one of the most difficult, fun, and frustrating bugs I have ever exploited.

Large language models (LLMs) that generate code are nowadays common. Since a couple of weeks, VS Code has an agent mode that performs multi-step coding tasks. I was actively involved in web development roughly 20–25 years ago, when CGI, Perl, and early versions of PHP were popular. I have no idea how modern web development actually works. I always had some projects in mind that I wanted to create, but I never had the time to dig into one of the modern JavaScript frameworks like React. GitHub Copilot now seems like a way to create (web) applications just by describing the requirements (i.e., vibe coding) for an entire application. This post describes my experience building a PostgreSQL query plan explorer using React and VS Code in two evenings—without writing a single line of code myself.

Another year, another version of my Polyglot Conway project, this time for C89, also known as “ANSI C”, targeting quite a few compilers of the early 1990s, and some others from our more recent times.

Thanks to the open nature of the whole stack WebAssembly is arguably much closer to “write once, run anywhere” than Java/JVM ever was.

tl;dr: We’re just starting on the biggest revolution in smart client and web client development technology in many, many, many years. Now is an extremely exciting time to be a smart client developer, or to rediscover smart client development if you (like me) have been hiding in server-side code over the past decade or so. WebAssembly is the technology that may reshape the way we build client-side software, and it is really cool!
