It was October of 2012 when
I posted http://vzimmer.blogspot.com/2012/10/250.html.
Over a year and a half later I have finally hit 300 issued US patents 300
issued. In later posts I talked about innovation and invention http://vzimmer.blogspot.com/2013/12/invention-and-innovation.html,
so I don't have much to add.
Probably closer to my mind
includes recent events. Since my last posting I had the opportunity to talk
with the industry about UEFI and testing. With Ricard Neri from Intel's Open
Source Technology Center I spoke at the UEFI Plugfest in Seattle last month.
Our presentation and video of the same on "Open Source Test Tools for UEFI” are located at http://www.uefi.org/sites/default/files/resources/2014_UEFI_Plugfest_04_Intel.pdf and https://www.youtube.com/watch?v=aV1DSF4cwGw,
respectively. I will pick up on some of the topics of open source security and
tools at the upcoming ToorCamp, too http://toorcamp.toorcon.net/talks/#16.
Other events that have occurred since my last posting
include publication of the UEFI 2.4 specification. Items of note there include
removal of the need to time stamp each UEFI network packet and manage volatile
variables for the network stack. This is important because the former entails a
call to the real-time clock (RTC), which is an expensive I/O operation on some
systems and may entail a system management mode interrupt (SMI) trap, which has
non-zero overhead to effect the world switch. Similarly on the volatile
variables. Many implementations of UEFI implement all of the variables in SMM
in order to protect authenticated variables, thus even an update to a volatile
variable in the performance path of the network stack can entail significant
overhead. My colleagues posted a paper on these issues of PXE performance at https://uefidk.com/sites/default/files/Intel_UEFI_PXE_Boot_Performance_Analysis.pdf.
Speaking of UEFIDK.COM site, I have been encouraged to blog there, but I have yet to wean myself off of this site. Hopefully my next blogs on UEFI will migrate to that location. From that site I'd also like to note the existence of

Intel® Firmware Support Package (Intel® FSP) For MinnowBoard

under http://www.uefidk.com/content/minnowboard-uefi-firmware. This shows how to adapt the Intel Firmware
Support Package, or 'consume' that binary, into an edk2 http://edk2.sourceforge.net tree.
Similar infrastructure code in the coreboot upstream at http://www.coreboot.org can be found to do
similar integration, or how to 'consume' the FSP http://review.coreboot.org/#/c/4018/.
These are two examples of workflows of
open source firmware ecosystems that allow for building platforms with the FSP.
To provide guidance around the FSP construction, on both the 'producer' and 'consumer' side, the Firmware Support Package (FSP) External Architecture Specification (EAS) has been posted to the location

http://www.intel.com/content/www/us/en/intelligent-systems/intel-firmware-support-package/fsp-architecture-spec.html.
This helps to lock down the interfaces so that the above listed firmware
ecosystems can align their 'consumer' source infrastructure codes.
Why FSP? Even
UEFI/Edk2 stalwarts like my good friend Tim Lewis, CTO at Insyde Software, have
expressed thoughts on using edk2 for embedded, including anecdotal commentary
such as http://uefi.blogspot.com/2014/04/the-tale-of-three-conferences.html
Many discussions around UEFI have to
do with complexity. And there is something to these discussions, since the very
power and flexibility of UEFI has led to implementations (like that on
tianocore.org) which are broken into hundreds of pieces, where assembling the
right one requires the right recipes.
Most embedded vendors don't need their firmware distribution to be as
complicated as their Linux distribution (see yoctoproject.org).
So you can think of FSP + EDK2 as one 'recipe', among many,
to ease the embedded workflow in various open source firmware ecosystems. FSP helps preserve the boundary of critical silicon initialization code, with some examples found in PI Silicon Init. This doesn't describe the only mechanism, of course. But given the end goal of booting an operating system, Mille viae ducunt homines per saecula Romam.
So enough of UEFI and FSP, an additional thought on this 'milestone day'
of 300 include a mention of a book that I enjoyed reading over the last few
weeks, namely Ben Horowitz's The Hard Thing About
Hard Things http://www.amazon.com/Hard-Thing-About-Things-Building-ebook/dp/B00DQ845EA/.
Ben was a leader at Netscape during the startup days, and his book ranks among
Andy Grove's High Output Management and Only the Paranoid Survive
as more proactive business books, or managing a business in a crisis. Specifically, Horowitz speaks of the distinction
between the "Wartime" versus "Peacetime" CEO. He notes how Eric
Schmidt was a peacetime CEO of Google, with features like the 20% time, versus
Larry Paige becoming a wartime CEO, and the more narrow but aggressive product
focus.
After reading Ben's book, the question I would pose is
if the same analogy works for engineers, or more generally, the employees.
Namely, are some employees better at peacetime, with the less stress and
ability to explore more things, than in wartime, with the enhanced focus? I personally find constraints help with focus, and Paige's 'Scarcity brings Clarity' comes to mind. Food for thought.
Speaking of thoughts, I'll close with thoughts on
co-workers who have departed. Over the last day I learned about a manager with
whom I worked since the last 90's has passed away. I learned a lot from his
mentoring, and I especially recall a quote he made about project development at
a technology company: "If upper management knew the true cost of an
R&D project, they would never fund it." Fare well, Doug.
A couple of additional thoughts are for technical colleagues still with the world, but who have recently retired from Intel. One is a Senior PE from Folsom on the CPU development team. I learned many things from Steve about the trade-off between hardware and software, especially disabusing me of the fact that 'the other guy's job is easier.' I relent and the CPU microarchitects win for complexity. Talking to Steve was like reading Colwell's tale http://www.amazon.com/Pentium-Chronicles-Politics-Landmark-Practitioners-ebook/dp/B001CBCRCA/. A parting quote from Steve that sticks with me is “You will not have all the answers, but in working with the right people, you can find them.“ So true. And thanks to the 'right people' who still answer my emails, pick up the phone, and look up from their monitors when I invade their cubicle.
And last but not least, I have to comment on the retirement of George Cox. George had a rich Intel career, including setting up the first intel.com website, CDSA, iWARP, the Intel 432, and one of his last achievements, the digital random number generator (DRNG) http://spectrum.ieee.org/computing/hardware/behind-intels-new-randomnumber-generator/0. On the latter I still recall George quoting John von Neumann, in Geoge's distinct West Texas accent: 'Anyone who uses software to produce random numbers is in a ``state of sin''' when discussing the DRNG work with me over lunch. That work, and the 432 http://en.wikipedia.org/wiki/Intel_iAPX_432, count as epic events in just one career, and I'm still a fan of hardware capabilities http://www.google.com/patents/US8312509, especially as it's tough for 'software to protect software.' We all need a little help from our hardware friends.

Since I started the thread with patents, I'll end with patents. Intel has been a great place to work. I joked on my Google+ channel that this is the closest I'll ever get to the C-suite in response to the patent award photo at https://plus.google.com/+VincentZimmer/posts/R764RmhX7tg. In reality, though, Intel has offered me an opportunity to work with some of the smartest people in the industry and learn from them. I only hope that I can contribute back a small percentage of what they have provided to me over the years.
And with that, off to work.
