Containers from first principles
You’ve likely heard everyone at the office or online proclaim that “K8s has eaten everyone’s lunch!” or that “everything should be in a docker container!”.
While there are advantages to the above methodologies; it’s very easy to have cargo-culted their adoption; especially for Kubernetes (K8s). I find the biggest problem however that there is a fundamental lacking of what is a *container.
There s a 1000 other posts online explaining containers and I’m adding my own to the pool. Perhaps this 1001th explanation will do so in such a way that it groks.
bpf_helpers and you...
This is a republishing of a e-mail I sent out to xdp-newbies mailing list which you can find here originally published on Wed, 30 Oct 2019
This is my attempt of a continuation of David Miller’s prior e-mail bpf.h and you….
I was curious about how ebpf filters are wired and work. The heavy use of C macros makes the source code difficult for me to comprehend.
Maybe there’s an online pre-processed version of the Linux kernel?

New blog. New format.
Hello World.
I’ve moved my blog from “Small Thoughts” blog.fzakaria.com, which was hosted on Wordpress & S3, one using Jekyll via Github Pages.
Why Github Pages and not S3 still? I wanted to see what all the fuss was about & it sounded simpler to set up the TLS certificates.
You may notice that the theme of this blog is very similar to that of Drew Devault’s; in fact, it is based on his published theme.
I admired on his blog his campaign to get others blogging that I revived my forgotten blog. I enjoyed the minimalism of his blog and embraced it. The site uses very minimal fancy Jekyll plugins, and you can find the source here.
I’m still a novice to Jekyll & blogging in general; feel empowered to reach out to teach me or discuss.
