Looking at the history of Unix stdio and how it manifests today: fingolfin.org/blog/20200327/…

New blog article on improving CPU performance counter support in illumos: fingolfin.org/blog/20191111/…. Also, a new blog 'engine' along for the ride.

Glad to see software.intel.com/security-softw… written up. Open question though: can spec exec forward an old gsbase past an unconditional swapgs? Given segment caches, makes you wonder. cc @jonmasters

Some writing on figuring out USB topology: dtrace.org/blogs/rm/2019/…

Next in the series: 'Transceivers: The Device Between the NIC and the Network': dtrace.org/blogs/rm/2019/…

A Tale of Two LEDs (and making them blink): dtrace.org/blogs/rm/2019/…

I took a moment to write on some recent work on temperature sensors: dtrace.org/blogs/rm/2019/…

@richlowe @jessfraz @postwait Both approaches can make sense. Happy to answer any questions related to it.

(unix: Could not start init)

@jussisallinen @joyent This is still a work in progress and in many ways far from reality. Hopefully it serves as an interesting point of discussion with folks and as we learn more, this will be updated and further fleshed out. Happy to take feedback, etc.

This type of detailed work is what divides @Joyent from the rest of the competition when evaluating open cloud platforms production readiness. Excellent document by @rmustacc eng.joyent.com/ras/

@rockncheeseband It's all in the repo and its history. See the stage directory. What's there is what I have.

Submit your talk for #SystemsWeLove by Oct. 18th! Looking for a variety of depths & styles for ANY systems you love: talks.systemswelove.com/submit/

No deed goes unpunished.

Another day, another painful firmware bug.

@polm23 And this is why everyone is confused that CPPFLAGS in makefiles aren't for C++ and rather are for the preprocessor.

@tuxology @bcantrill No. This refers to the Compact C Type Format, the way DTrace gets type information. See illumos.org/man/4/ctf.

@sjorge I don't know. @bcantrill or @joyent should be able to answer that for you.

Come for DTrace, stay for all the ridiculous and esoteric CTF demos! twitter.com/bcantrill/stat…

Happy to get my SMAP work upstream into illumos as well (github.com/illumos/illumo…).
