Over the past year I’ve refined my approach to arena allocation . With practice, it’s effective, simple, and fast; typically as easy to use as garbage collection but without the costs. Depending on need, an allocator can weigh just 7–25 lines of code — perfect when lacking a runtime . With the core details of my own…
From the operating system's point of view, we have a large pool of memory from some starting address to some ending address. We can use our linker script (the virt.lds file) to provide us symbols representing the address of the starting and ending points.
In this regularly but rarely updated article, which is without doubt the most comprehensive list of Linux distributions' problems on the entire Internet, we only discuss their main problems and shortcomings (which may be the reason why some people say Linux distros are not ready for the desktop) while everyone should…
Perhaps the most often repeated complaint about Rust is its slow feedback loop and long compilation times. I hear about it all the time; in Rust podcasts, blog posts, surveys, conference talks or offline discussions. I also regularly complain about it, being a Rust user myself!
Over the last decade, we’ve seen great advancements in distributed systems, but the way we program them has seen few fundamental improvements. While we can sometimes abstract away distribution (Spark, Redis, etc.), developers still struggle with challenges like concurrency, fault tolerance, and versioning. There are…

You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Why does Space Station 14 crash with ANGLE on ARM64? 6 hours later…
Now that the CoreCLR is open-source we can do fun things, for instance find out if it’s possible to add new IL (Intermediate Language) instruction to the runtime.
On UNIX-like operating systems, userland processes invoke kernel procedures using the "syscall" feature. Each syscall is identified by a "syscall number" and has a short list of parameters, which both can vary between operating systems, hardware platforms, and configuration options.

Update Dec 20, 2012 : Apple appears to have fixed this in a way by adding a “Keep changes in original document” checkbox in the save dialog. Bandaids are better than nothing. It is also possible to add a keyboard shortcut for Save As, which is partially hidden (option key).
tl;dr I found several bugs in apk, the default package manager for Alpine Linux. Alpine is a really lightweight distro that is very commonly used with Docker...
Pipelines - a guided tour of the new IO API in .NET, part 1 (part 2 here) About two years ago I blogged about an upcoming experimental IO ...
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.
Ever since I got AMD, Intel, and Nvidia graphics cards to run on a Raspberry Pi, I had a nagging question: What's the point? The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That's not much. Especially considering a modern desktop has at least one slot with 16 lanes of…
Kenton Varda introduces the next iteration of Cloudflare's Durable Object platform, which recently upgraded from a key/value store to a full relational system based on SQLite. For useful background on …
Over the past years, the adoption of RocksDB increased dramatically. It became a standard for embeddable key-value stores.
It is time to celebrate EC2-Classic, which defined early cloud computing, and which is finally retiring.
My last post on the Rust compiler’s performance was two months ago and a lot has happened since then.
This is an effort to create a fully functional Kubernetes cluster with 1 million active nodes.
An overview of erasure coding, its trade-offs, and applications in distributed storage systems.
This is an introductory overview post for the Linux Graphics Stack, and how it currently all fits together. I initially wrote it for myself after having conversations with people like Owen Taylor, Ray Strode and Adam Jackson about this stack. I had to go back to them every month or so and learn the stuff from the…
