During the last year and a half, I wrote a book on server-side WebAssembly. Getting into Wasm is hard. Resources are scattered, the tech is complex, and it's constantly changing. I wanted to contribute a resource to make learning easier. manning.com/books/server-sid… (1/5) 🧵

"Server-side WebAssembly" — kindly gifted and signed by @danologue at #WasmCon26 🙏 manning.com/books/server-sid… #WebAssembly #Wasm #WasmCon

Can you combine Wasm sandboxing with hardware isolation and still avoid slow cold starts? @danologue breaks down two approaches: • No OS (just memory and CPU) • Microkernel (controlled syscalls and more support) Catch him March 23rd at 10:40am CET: hubs.la/Q047Qbby0 45% off his book with code KubeConEU26: hubs.la/Q047Qf4M0

I've been working on making it easier to run higher-level apps (e.g., Python) in #Hyperlight by adding POSIX support to our micro-VMs. Posted about it on MSFT's OSS blog (see below). It features a demo w/ Hyperlight micro-VMs running AI generated code :) opensource.microsoft.com/blo…

Another book gone to print this week. I like the assembly angle. Early in my career I wrote a fair bit of 6502 assembly, 8086 assembly, and even quite a bit of Xerox Sigma VI assembly. Those were good days, and I enjoyed dropping into assembly from the various higher level languages I was coding in. Sometimes my doing that was justified, and other times I really shouldn't have. We grow in wisdom (hopefully!) as we progress in life. #wasm #webassembly #assembly @danologue @ManningBooks manning.com/books/server-sid…

Kubernetes shouldn’t have to choose between speed & safety. See how Hyperlight and Nanvix combine container-level performance with VM-level isolation. Watch @danologue’s live demo at @rejektsio (15:10 EST): hubs.la/Q03ScNf_0 Check out Dan's book in our KubeCon bundle: hubs.la/Q03ScL7G0
