Linux Internals: How /proc/self/mem writes to unwritable memory (2021)
Introduction An obscure quirk of the /proc/*/mem pseudofile is its “punch through” semantics. Writes performed through this file will succeed even if the destination virtual memory is marked unwritable. In fact, this behavior is intentional and actively used by projects such as the Julia JIT compiler and rr debugger…

We should revisit literate programming in the agent era
Literate programming is the idea that code should be intermingled with prose such that an uninformed reader could read a code base as a narrative, and come away with an understanding of how it works and what it does. Although I have long been intrigued by this idea, and have found uses for it in a couple1 of different…

Pushing and Pulling: Three reactivity algorithms
It’s looking like I’m going to need to build a reactive engine for work, so I’m going to prepare for that by writing down what I know about them. I want to look at three ways of building reactive engines: push reactivity, pull reactivity, and the hybrid push/pull combination that is used in a bunch of web frameworks…

Boy I was wrong about the Fediverse
I have never been an "online community first" person. The internet is how I stay in touch with people I met in real life. I'm not a "tweet comments at celebrities" guy. I was never funny enough to be the funniest person on Twitter. So when Twitter was accidentally

C# strings silently kill your SQL Server indexes in Dapper
If you're using Dapper with anonymous objects to query varchar columns, you're probably sending nvarchar(4000) parameters — causing CONVERT_IMPLICIT on every row and defeating your indexes. Here's the fix.

The window chrome of our discontent
In a WWDC 2011 session, Dan Schimpf explained some of the goals of the refreshed design for Aqua in Mac OS X Lion were “meant to focus the user attention on the active window content”. This sentiment was echoed by John Siracusa in his review of Lion for Ars Technica: Apple says that its goal […]

macOS Tahoe windows have different corner radiuses
I’m sometimes late to notice new and terrible things about macOS 26 Tahoe, because I use it only for testing, on a secondary Mac. My main Mac remains on Sequoia, as enforced by Little Snitch . I was of course aware that app windows on Tahoe have exaggerated corner radiuses, but I was unaware until now that the window…
