"Readers will be familiar with Mask-Step-Index (MSI) hash tables, a technique for building fast, open-addressed hash tables in a dozen lines of code. If multiple threads or processes access an MSI table with at least one still inserting elements, care must be taken to avoid data races. This article will show how to add atomic operations to MSI tables in order to support different concurrency constraints."

"This past Tuesday I typed C-x C-c in Emacs for the last time after 20 years of daily use. Though nearly half that time was gradually retiring it, switching to modal editing, then to Vim. Emacs is a platform, and I’d grown accustomed to its applications, especially those I built myself. There was no particular hurry, so replacements came slowly. With my newly-acquired superpowers I could knock out the last two pieces in a few days’ work, namely M-x calc with stackcalc and Elfeed with Elfeed2. I’m especially excited about the latter because it already exceeds the original. Both are multi-platform, native C++ GUI applications using native UI components."

"The new w64devkit release two weeks ago is the first to be code-signed with my identity, verified by Microsoft’s certificate chain. Currently only the release packaging is signed — the self-extracting archive and its payload — but I will soon code-sign individual EXEs and DLLs within the distribution. In fact, all Windows builds of my project releases have been code-signed the past two weeks, including dcmake, and so should everything going forward. My signing identity builds reputation with each download, so users will have an easier time with SmartScreen, and security software generally. Azure Artifact Signing creates the actual signature, but the rest is done with new infrastructure I built myself, aas-sign. As is often the case, the existing options were deficient for my needs, so I had to build it myself."

"CMake has a --debugger mode since 3.27 (July 2023), allowing software to manipulate it interactively through the Debugger Adaptor Protocol (DAP), an HTTP-like protocol passing JSON messages. Debugger front-ends can start, stop, step, breakpoint, query variables, etc. a live CMake. When I came across this mode, I immediately conceived a project putting it to use. Thanks to recent leaps in software engineering productivity, I had a working prototype in 30 minutes, and by the end of that same day, a complete, multi-platform, native, GUI application. I named it dcmake (“debugger for CMake”). I’ve tested it on macOS, Windows, and Linux. Despite only being couple days old, it’s one of the coolest things I’ve ever built. Prior to 2026, I estimate it would have taken me a month to get the tool to this point."
