The content discusses the integration of Sorbet typechecking support into RSpec through a gem called `rspec-sorbet-types`. This allows users to specify type annotations in their tests, enhancing type safety. To set it up, users need to add the gem to their Gemfile, adjust their `require.rb` to include RSpec, and regenerate type definitions using Tapioca. If using Rails, adjustments to the test schema maintenance are necessary. Once set up, users can use basic RSpec

The post discusses the diagnosis and resolution of two crashes in Go related to frame pointer unwinding, caused by faulty assembly code that inadvertently overwrote the frame pointer without properly saving and restoring it. The problems manifested in two ways: one instance involved clobbering the frame pointer register, while the other affected a saved frame pointer on the stack. The issue was tied to the Go 1.23 version, specifically when using profile-guided optimization (PGO) and primarily impacted programs built for

The author is active on X/Twitter as @brandur and on Bluesky at brandur.org. Recently, an implementation for UUIDv7 was added to Postgres, offering advantages over traditional UUIDv4, such as improved performance during inserts with ordered structures like B-trees due to more deterministic ordering based on the current time. A notable feature of this implementation is that the random portion of the UUIDs is monotonic within each Postgres backend, achieved by storing a sub-millisecond timestamp that

At the end of 2024, Harold Aptroot shared his disappointment regarding the SHLX instruction on Alder Lake processors, describing it as a "medium latency" instruction that takes 3 cycles, unlike the 1 cycle it takes on other CPUs. SHLX, part of the BMI2 instruction set, does not affect the FLAGS register and is typically a 3-operand instruction. Tavian Barnes, intrigued by this discrepancy, noted that while Alder Lake's efficiency cores execute SHLX in 1
