• TLS Certificate Transparency is about improving the (web) TLS ecology

  In Emily M. Stark's Certificate Transparency is really not a replacement for key pinning, one thing that Stark notes is that Certificate Transparency doesn't really have strong security properties. You can say some fuzzy things about security properties that CT perhaps offers (although they get fuzzier when you look at the details), but there's very few concrete security claims you can make (or that people try to make, for example in RFC 9162). Having been thinking about this for a while, I think that Stark is correct here, and that Certificate Transparency is not about security as much as it is about improving the 'Web PKI' ecology

• Void Linux root on an encrypted ZFS mirror with syslinux MBR and ZFSBootMenu

  In this tutorial I am going to use Void Linux to "replicate" how FreeBSD is utilizing ZFS snapshots for boot environments. I am going to use a MBR based setup with a native ZFS encrypted root mirror. With a ZFS root mirror we not only get the benefits of ZFS snapshots, but we also get the benefits of ZFS' ability to auto repair any corrupted data (from things like bit rot). And in case one of the hard drives fail, we can quickly replace the broken disk with a new disk and have everything up and running again in a very short time.

• Style performance and concurrent rendering

  I was fascinated recently by “Why we’re breaking up with CSS-in-JS” by Sam Magura. It’s a great overview of some of the benefits and downsides of the “CSS-in-JS” pattern, as implemented by various libraries in the React ecosystem.

  What really piqued my curiosity, though, was a link to this guide by Sebastian Markbåge on potential performance problems with CSS-in-JS when using concurrent rendering, a new feature in React 18.

• How to get your CPU using the terminal?

  In IT service, many times we don’t know the hardware models of the computer to be serviced or configured. Therefore, it is useful to know how to get your CPU using the terminal.

  Although a user with some technical knowledge can find out what CPU a computer has by checking the box it comes in, others may not know how to do this. Or even in a professional environment where you have to access remotely, it is another factor to consider.

  On the other hand, knowing the exact model of the CPU can help us in configuration scripts where we need it.

  Let’s go for it.
