Linux 7.4 Begins Landing Patches To Speed Up The Kernel Build Process

Thu, 22 Oct 2026 09:00:00 +0000

There are notable patches by Arm engineer Lorenzo Stoakes that have begun landing in Linux 7.4 for speeding up the Linux kernel build process. This work can provide some significant reductions in the Linux kernel build time…

Linux 7.3 Squeezes Even More Performance Out Of The AMD Threadripper PRO 9995WX

Sun, 18 Oct 2026 09:00:00 +0000

On October 16, 2026, Michael Larabel published the latest in a long-running Phoronix series: benchmarks of the Linux 7.3 kernel state on a 96-core AMD Ryzen Threadripper PRO 9995WX workstation (192 threads), comparing it against the shipping Linux 7.2. The headline, in the author’s words, is that the kernel “looks great” — and the numbers back it up. I/O tests for PCIe Gen 4/5 NVMe storage posted clear gains, and that I/O improvement propagated into real application workloads: PostgreSQL, MariaDB, and TigerBeetle (the Go-based financial-transactions database) all ran faster on 7.3, network throughput came up, and the kernel’s own micro-benchmarks — fork, io_uring, and mutex contention — all moved. Compilation workloads were “subtly but consistently faster,” and CPU-based AI inference showed small gains.

Go 1.27 is released

Sat, 17 Oct 2026 09:00:00 +0000

Go 1.27 was released in August 2026, and it is one of the larger releases in the language’s history: generic methods finally exist, the standard library gained a uuid package, a new post-quantum signature scheme made it into crypto/tls and crypto/x509, a long-anticipated encoding/json/v2 package landed (and quietly became the implementation behind the v1 encoding/json), the runtime got size-specialized memory allocation and a generally-available goroutine-leak profile, and the toolchain gained a batch of new go fix modernizers.

Go Power: Microsoft’s Bold Bet on Faster TypeScript Tools

Sat, 17 Oct 2026 09:00:00 +0000

Go Power: Microsoft’s Bold Bet on Faster TypeScript Tools

In March 2025, Anders Hejlsberg — co-creator of TypeScript — announced Corsa, an initiative to port the TypeScript compiler and its language service to a native implementation written in Go. The numbers behind the bet: build times down by roughly 10x, project load 8x faster, and about half the memory usage of the JavaScript implementation, with a language service that makes completions, quick info, go-to-definition, and find-all-references dramatically snappier.

Introducing the pkg.go.dev API

Sat, 17 Oct 2026 09:00:00 +0000

For years the only way to get data out of pkg.go.dev was to scrape the HTML. Dependency dashboards, CI checkers, internal package browsers, and — increasingly — AI assistants that need to reason about the Go ecosystem all ended up parsing <a> tags from rendered package pages. That was never going to survive a refactoring. On May 21, 2026, the Go team shipped the fix: an official, documented, versioned REST API for pkg.go.dev, currently served under the /v1beta path, with a machine-readable OpenAPI specification published alongside it.

Linux Lands Fix for Rare, Varying SMP Boot Hangs Affecting Kernels Since 2024

Linux Lands Fix for Rare, Varying SMP Boot Hangs Affecting Kernels Since 2024

Kernel bugs that are rare and vary by hardware are the hardest kind to diagnose, because the reproduction is not a unit test you can run on a loop — it is a race that only fires when the scheduler happens to place one thread on one CPU at one exact millisecond of boot. That is exactly the class of bug Linus’s tree just fixed ahead of Linux 7.3, and it is a clean case study in concurrency timing that maps one-for-one onto Go: a set of worker threads that start too early, race a global setup phase, and intermittually deadlock the system.

Platform-independent SIMD in Go

Sat, 17 Oct 2026 09:00:00 +0000

Before 1.26, the only way to get SIMD performance out of a Go program was to write Go assembly, a bar high enough that plenty of code that could vectorize simply never did. The experimental archsimd package (1.26) lowered that bar for amd64, and 1.27 extends it to arm64 NEON and wasm. But architecture-specific SIMD has a second problem that assembly never fully solves: the platforms disagree about everything — vector sizes, which operations exist, how masks are represented, which features need runtime detection. amd64 has 128/256/512-bit vectors; arm64 has 128-bit NEON and 128–2048-bit SVE; wasm has a single fixed 128-bit size. AVX512 uses dedicated mask registers; NEON and wasm get by with vector bitmasks; SVE allocates one bit per byte with the least-significant bit governing the operation.

Results from the 2026 TAB election

Sat, 17 Oct 2026 09:00:00 +0000

On October 16, 2026, LWN reported a small headline with outsized consequences for anyone who runs Go on Linux: the results of the 2026 election for the Linux Foundation Technical Advisory Board (TAB) were announced. Kees Cook, Dave Hansen, Miguel Ojeda, and Shuah Khan have all been re-elected, and Laurent Pinchart is joining the board.

The announcement is three sentences long. The reason it matters is that the TAB is the top rung of the governance chain that every line of the Linux kernel passes through before it lands — and the people who are re-elected there decide what the kernel is allowed to be. If your production Go servers, your golang.org/x/ dependencies, your containers, and your eBPF programs all sit on top of the Linux kernel, the TAB is where the rules get made. This post unpacks what the TAB actually is, how the kernel’s governance chain works, what the 2026 roster change means, and what it implies for Go developers in practice.

Type Construction and Cycle Detection

Sat, 17 Oct 2026 09:00:00 +0000

Type Construction and Cycle Detection

Go’s static typing is a big part of why it is a good fit for production systems that have to be robust. Every time go build runs, the compiler first parses each package into an AST and hands that AST to the type checker. In Go 1.26, the language team overhauled a part of that type checker that most programmers never think about: how it constructs types, and how it detects when a type’s definition is circular. The result: a simpler construction algorithm, and a class of corner-case compiler panics that now produce ordinary type errors.
