Very interesting use case of using #OSv_unikernel to build fast and very resource-efficient server-less platform - fosdem.org/2024/schedule/eve…

The recording of my #FOSDEM24 talk about the most recent OSv enhancements has been just released - video.fosdem.org/2024/ud2208…! Tune in to learn about how we use Xconfig to build a custom kernel of 788K in size that runs an app with only 1.2MB of memory.

OSv can now run statically linked executables as well as dynamic ones via Linux' ld-linux-x86-64.so.2 instead of OSv's built-in dynamic linker. Stay tuned when this is going to officially land on master!

Among the clearest explanations of "why functional programming?" that I have seen: inner-product.com/posts/fp-w…

What Functional Programming Is, What it Isn't, and Why it Matters

The core premise of functional programming, in my opinion, is that local reasoning and composition make for better code. Here I discuss what these terms mean and the benefits they bring.

We have just brought the aarch64 edition back to life! OSv arm can now also boot on Raspberry Pi 4 with QEMU and KVM acceleration on. The aarch64 port is still quite behind the x64 so if you want to help us make it better send some patches! Please see groups.google.com/d/msg/osv-…

Building OSv images has become even easier with newly released capstan v0.4.1! Added ability to compose images rapidly by specifying list of required packages as command line parameters. Now also possible to run OSv on Mac using Docker's #Hyperkit and QEMU with Intel HAXM.
