I’m working on more posts about the Catalina release, but I wanted to start with a short warning. I’ve heard a bunch of reports of data loss in Apple Mail. Thankfully, none seem to be caused by my apps . (Ironically, one of the bugs I’ve encountered is the inability to delete messages via AppleScript.) And, in fact…
Back in summer I have read a new bookpublished by one of the core Intel architects about the Management Engine (ME).I didn’t quite like what I read there. In...
How would you build an operating system? My answer is I wouldn't. First off, I don't know how. And the second thing is it seems like to large of a task. It took thousands of developers to build Windows XP. But actually, it is possible to build an operating system from scratch. My guest is doing it. Andreas Kling…
More or less anyone using modern PCs has to wonder: Why does Windows use backslash as a path separator when the rest of the world uses forward slash? The clear intermediate answer is “because DOS and OS/2 used backslash”. Both Windows 9x and NT were directly or indirectly derived from DOS and OS/2, and certainly…
The original ANSI C standard, C89, introduced the concept of “undefined behavior,” which was used both to describe the effect of outright bugs like accessing memory in a freed object and also to capture the fact that existing implementations differed about handling certain aspects of the language, including use of…
Next time you look at a transmission line, I hope you'll focus on the big four properties: characteristic impedance, high-frequency loss, delay, and cros...
I unlocked Hypervisor.framework on my jailbroken phone and modified UTM, a popular QEMU port for iOS, to run arm64 Linux in a VM at full native speed. …for the clickbait - and to show iPhone’s untapped potential.

zswap and zram are fundamentally different approaches with different philosophies. If in doubt, use zswap.
This post discusses how maps are implemented in Go. It is based on a presentation I gave at the GoCon Spring 2018 conference in Tokyo, Japan.
TL:DR Successive, well intentioned, changes to architecture and technology throughout the lifetime of an application can lead to a fragmente...
This is the introduction of a multipart series. It is to give a high level overview without really deeply diving into any individual component.
I ended up getting a response from high level people at AMD. It was still very light on any real technical information, but it did include some great phrases like “I am able to replicate the issues you are facing” and some mockable phrases like “We are hoping that this will improve your perception of AMD products and…
In P of EAA I said "don't distribute your objects". Does this advice contradict my interest in Microservices?
When Apple introduced Bitcode and made it mandatory on watchOS and tvOS, they kinda hand-waved away questions about why it existed, with nebulous claims about it being useful to tune-up binaries by utilizing the latest compiler improvements.
This page lists some of the changes I make to a vanilla install of FreeBSD for security hardening. Some changes to increase network performance or make things a bit more sane are also included. It only covers basic changes that a sysadmin can make to a running system.
This article was supposed to be published all at once on July 30'th. But because of the staggered launch delay into August 8 and 15, some sections of this article were redacted until August 14th.
Then come along! Let’s make a compiler that goes all the way from source to assembly from scratch—no shortcuts!

Preface This is a technical article chronicling one of the most interesting bug hunts I’ve had the pleasure of chasing down. At AdGear Technologies Inc. where I work, ssh is king. We use it for management, monitoring, deployments, log file harvesting, even some event streaming. It’s solid, reliable, has all the…
