The insanity of being a software engineer
Software gets more complicated. All of this complexity is there for a reason. But what happened to specializing? When a house is being built, tons of people are involved: architects, civil engineers, plumbers, electricians, bricklayers, interior designers, roofers, surveyors, pavers, you name it. You don’t expect a single person, or even a whole single company, to be able to do all of those. ↫ Vitor M. de Sousa Pereira I’ve always found that softwa … ⌘ Read more

Apple’s Darwin OS and XNU kernel deep dive
Apple’s Darwin operating system is the Unix-like core underpinning macOS, iOS, and all of Apple’s modern OS platforms. At its heart lies the XNU kernel – an acronym humorously standing for “X is Not Unix.” XNU is a unique hybrid kernel that combines a Mach microkernel core with components of BSD Unix. This design inherits the rich legacy of Mach (originating from 1980s microkernel research) and the robust stability and POSIX compliance of BSD. The … ⌘ Read more

Windows Hotpatch comes to client version of Windows
Good news for Windows users, and for once there’s not a hint of sarcasm here: Microsoft has started rolling out Windows Hotpatch to the client versions of Windows. This feature, which comes from the server versions of Windows, allows the operating system to install patches to in-memory processes, removing the need for a number of restarts. Obviously, this is hugely beneficial for users, as they won’t have to deal with constant r … ⌘ Read more

How big is VMS?
This question was asked during my Boot Camp presentation last fall in Boston, and over the past 35 years dozens of times people have asked, how big is VMS? That translates into “how many lines of code are in VMS”? I thought it was time to at least make a stab at pursuing some insight into the answer. I wrote some command procedures to count the number of source lines in .B32, .B64, .C, .MAR, .M64, and .S files. Not counted are blank lines and lines beginning with the standard comment characters and m … ⌘ Read more

Literally Windows on arm: here is Windows running on the Pixel Watch 3

Microsoft releases Windows 11 roadmap tool to help make sense of Windows 11’s development

Google moves all Android development behind closed doors
Up until now, Google developed several components of Android out in the open, as part of AOSP, while developing everything else behind closed doors, only releasing the source code once the final new Android version was released.
