The behavior of the Windows scheduler changed significantly in Windows 10 2004 (aka, the April 2020 version of Windows), in a way that will break a few applications, and there appears to have been …
Taking a second look at the newly introduced mask registers, this time with the benefit of a SKX die shot from Fritzchens Fritz.
You’ve likely heard everyone at the office or online proclaim that “K8s has eaten everyone’s lunch!” or that “everything should be in a docker container!”. While there are advantages to the above methodologies; it’s very easy to have cargo-culted their adoption; especially for Kubernetes (K8s). I find the biggest…
Huawei has seemingly stepped its foot into the kernel self-protection game with the release of HKSP. Absent any threat model and riddled with weaknesses, it also introduces a trivially exploitable local root vulnerability due to a complete lack of defensive programming.
This is Part 3 in a series of posts describing the Raft distributed consensus algorithm and its complete implementation in Go. Here is a list of posts in the series:
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…
This investigation started, as so many of mine do, with me minding my own business, not looking for trouble. In this case all I was doing was opening my laptop lid and trying to log on.The first fe…
This is Part 2 in a series of posts describing the Raft distributed consensus algorithm and its complete implementation in Go. Here is a list of posts in the series:
Large-scale distributed software systems are composed of several individual sub-systems—such as CDNs, load balancers, and databases—and their interactions. These interactions sometimes have unpredictable outcomes caused by unforeseen turbulent events (for example, a network failure). These events can lead to…
Facts, directions, and thoughts regarding the evolution of OpenBSD framebuffer consoles
We'll get to the shrinking, but first let's motivate the binary in question. Three years ago I wrote the "Surfacing Hidden Change to Pull Requests" post which covered pushing important stats and diffs into PRs as a comment. This avoids surprises with changes that affect binary size, manifests, and dependency trees.
After a small delay * , the NetBSD Project is pleased to announce NetBSD 9.1 , the first feature and stability maintenance release of the netbsd-9 stable branch.
From the very beginning of Slack, MySQL was used as the storage engine for all our data. Slack operated MySQL servers in an active-active configuration. This is the story of how we changed our data storage architecture from the active-active clusters over to Vitess — a horizontal scaling system for MySQL. Vitess is…
The rules of logic no longer apply when you cross the line.
Explore many performance improvements, big and small, that have gone into the .NET 5 runtime and core libraries to make apps and services leaner and faster.
When we launched S3 back in 2006, I discussed its virtually unlimited capacity (“…easily store any number of blocks…”), the fact that it was designed to provide 99.99% availability, and that it offered durable storage, with data transparently stored in multiple locations. Since that launch, our customers have used S3…
In Prague, the C++ committee took a series of polls on whether to break ABI, and decided not to. There was no applause. But I’m not sure we fully understood what we did and the consequences it could have.
Introduction: Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32
Updated 11/16/2021: x64 emulation for Windows is now generally available in Windows 11. For those interested in experiencing this, a PC running Windows 11 on Arm is required. Today, we're releasing the first preview of x64 emulation
Cloudflare is a security company, and the heart of Workers is, in my view, a security project. Running code written by third parties is always a scary proposition, and the primary concern of the Workers team is to make that safe.
As AI and HPC datasets continue to increase in size, the time spent loading data for a given application begins to place a strain on the total application’s performance. When considering end-to-end…
