Tiger Data (Creators of TimescaleDB) sponsor [Proposal: `go run -c 'code here'`](https://groups.google.com/g/golang-nuts/c/tVWOr0zXF08/m/Bq1HaTBpCQAJ) β€” Some languages (like Python or Ruby) let you run once-off arbitrary bits of code as a one-liner from the terminal. Could Go do the same? Ian Lance Taylor, Rob Pike, and others weighed in on the idea in this [golang-nuts](https://groups.google.com/g/golang-nuts) thread. Dan Kegel et al. **IN BRIEF:** - [Go 1.27 Release Candidate 2](https://groups.google.com/g/golang-nuts/c/OAYrh9u-O-4) has been released. - [Go 1.26.5 and 1.25.12 have been released](https://groups.google.com/g/golang-nuts/c/HatL1GnWess) including two security fixes. - The Go vulnerability database now [marks `golang.org/x/crypto/openpgp` as unsafe](https://pkg.go.dev/vuln/GO-2026-5932), so `govulncheck` will start throwing warnings if you're using it. - [gopls 0.23.0](https://go.dev/gopls/release/v0.23.0) is the latest release of Go's official language server with fleshed out Go 1.27 support and an `sqlrowserr` analyzer that catches missing `sql.Rows.Err()`checks. **PROPOSAL UPDATES:** - [`maps.Same` (formerly `Identical`) is coming to the standard library](https://github.com/golang/go/issues/78456#issuecomment-4917830579) as a way to identify if two maps share the same underlying storage. - `x/net/http2`'s standalone `Transport` and `Server` types [are now going to be deprecated](https://github.com/golang/go/issues/78064) (proposal accepted two days ago). - [`sync/atomic` may be gaining `Max` and `Min` operations](https://github.com/golang/go/issues/63999) (becoming a 'likely accept' two days ago). [`mmap` vs `pread` in a Real Go Storage Engine](https://internals-for-interns.com/posts/mmap-vs-pread-go-storage-engine/) β€” A surprisingly thorough tour of how the VictoriaMetrics filesystem layer reads bytes: `mmap` when `mincore` says pages are resident, `pread` when a major page fault might block a Go thread. Phuong Le [Go Interfaces, Reflection, And Binary Size](https://utcc.utoronto.ca/~cks/space/blog/programming/GoInterfacesReflectAndBinarySize) β€” As we learnt in JesΓΊs Espino's [deep dive into `reflect`](https://internals-for-interns.com/posts/go-runtime-reflect/), reflection keeps extra type metadata around, but it also stops the linker stripping unused methods.
