Reminder: I offer free mentoring and mock interviews. Embed sys, C++, perf analysis, at-scale monitoring, and more. Grab a spot on my calendar at calendly.com/kc8apf.

Hot take: FPGAs are just very, very long instruction word (VVLIW?) processors

Guess I'm going to be the one to write an IPMI performance benchmark.

TFW you recognize throughput is varying with latency because every IPMI implementation sends requests sequentially instead of pipelining.

A #mastodon exclusive! You are invited to play on a *REAL* PDP-8/e running the TSS/8 monitor (TimeSharing System 8) pictured here. There is a user contributed tutorial here:

To connect, ssh tss8@tty.livingcomputers.org

If you are unable to connect that means all 6 (yes, just 6) lines are in use. Remember, this is real hardware and there is NO EMULATION happening. It is the real deal! Enjoy!

I'm coming to CanSecWest for the first time in 2020 and I'm bringing "Finding Firmware Implants" training to the Dojo with me. cansecwest.com/dojos/2020/firm

My day was spent in ISE 14.7. I could have been 8x as productive if it was multithreaded.

Ah, the winter holidays. The time when I inevitably overload myself with things like moving to another state, buying one house and selling another, tearing apart a car to send it off for bodywork restoration, and keep going at my day job. πŸ˜‚πŸ˜΄

The recordings of this year's #Open Source #Firmware Conference are now online, finally. :) Playlists are available. \o/

Yes. I did just put pumpkin pie and ice cream in a bowl and called it pumpkin pie a la mode.

Me: finds major security holes in BMC virtual media feature
Also Me: uses virtual media to install OSes on servers in another state

Starting my work day as usual: waking up my laptop and letting Windows spend 30 minutes applying updates.

TIL SunPlus has two homegrown ISAs: μ'nSP and S⁺Core 7.

Only 12 hours to image 2 laptops with their factory image and apply all the firmware and OS updates. Now they are all ready for surgery tomorrow.

Test Laptop: WARNING!! Machine is in an uncommitted state!
Me: Is this laptop hitting on me?

Every time I decide to make something as a gift, it takes _so_ much longer than I expected and I miss the deadline.
