Technology Short Take 134

Welcome to Technology Short Take #134! I’m publishing a bit early this time due to the Thanksgiving holiday in the US. So, for all my US readers, here’s some content to peruse while enjoying some turkey (or whatever you’re having this year). For my international readers, here’s some content to peruse while enjoying dramatically lower volumes of e-mail because the US is on holiday. See, something for everyone!

Networking

Security

  • I’m glad to see this. Open source has become so critical to so many aspects of our computing infrastructure.
  • OpenCSPM looks like it could be quite a useful tool. I haven’t yet had time to dig in and get familiar with the details, but what I have seen so far looks good.
  • Uh oh…more hardware exploits.
  • The macOS OCSP fiasco generated quite a bit of attention and analysis (see here and here).

Cloud Computing/Cloud Management

Operating Systems/Applications

  • One of the things I love about Matt Oswalt is that he exemplifies the idea of a perpetual learner. The latest example is Matt’s post on the anatomy of a binary executable, in which he dives deep into what exactly it means to be a binary executable file. Good stuff!
  • You may have heard of eBPF, the Linux technology that is reshaping Linux applications (and in some ways reshaping Linux itself). Brendan Gregg discusses the future of BPF binaries, made possible through BTF and CO-RE. The idea of creating ELF binaries (don’t know what that is? See the previous bullet!) for BPF is pretty cool, in my opinion, and has the potential to unlock a lot of innovation in this space.
  • Something about Linux, and Fedora in particular, just keeps drawing me back. If you’re in a similar boat, and you’re looking for information on how to get Firefox on Fedora to play H.264 videos, Leo Chavez has some information that should help.
  • Here’s a bit of history on macOS, for those of us interested in such things.
  • This looks horribly confusing. It almost feels like we are well into Windows Registry territory here.
  • What a time to be alive: Microsoft has its own Linux distribution.
  • Whether it be dissatisfaction with macOS 11 “Big Sur,” or unhappiness at the direction of their hardware (there’s some discussion that the new M1 chips don’t support eGPUs), or concerns over privacy given the recent issues with OCSP and macOS “dialing home,” I’m seeing folks leaving macOS for other platforms (mostly Linux). Preslav Rachev shares his story here, and Juan Diego Caballero shares his story here.

Storage

Virtualization

That’s all this time, but hopefully it’s enough! If you have suggestions for content to include in a future Technology Short Take, or if you’d just like to catch up and say hello, feel free to contact me on Twitter. Enjoy the rest of your week!
