That's so sick. Some srsly mindblowing stuff there... cool it see it advance. The "grinds" were creative and very skating like.
The scenery reminds me a lot of the Industrial Revolutions video:

My concern wouldn't be the reduction of .4 mm. There's probably plenty of meat still there. My concern would be the potential for a stress riser where the cut stops/starts. With such a small amount of material being removed it seems like it would be difficult to make a good taper from one size to the next. I'm neither an engineer nor a machinist, but seat posts are one of the components that I'd avoid modifying.

The axial compression stress will usually still exceed the bending tensile stress. So the post will be in net compression around its circumference. Now, a lot of this depends on your seat position relative to the axis of the seatpost and how much of a fat ass you are.

A month ago everyone jumped down my throat for suggesting that a seatpost cut by a hacksaw wielding jackass might be unsafe due to stress risers. Now a seatpost turned down .002 by a caliper wielding machinist is "iffy" due to those same stress risers. 
I'm sure all the seatpost safety experts here can tell me what torque spec y'all used on your seat clamp bolts. Oh, wait... I'm the guy who was ridiculed for looking for an installation manual so that I could get the torque spec on a part. Oh yeah.... nevermind.

I forgot about that part of it. So if the post has setback, and the saddle is slammed rearward, that adds to the bending force. How about the rocking and twisting forces? Would they play a role?

Depends on your riding technique. The way I ride, I keep my hips steady and don't rock much on the saddle, nor do I twist on it. The saddle is meant to be a perch to support most of your weight, and not a reaction point for pedal forces. Basically, the pedal forces are transferred to the handlebar, which is why handlebars and stems are more likely to break than seatposts. Try riding no-handed, and see how much power you can get to the pedals, not much.

The grinds were my favorite. When I shared the video on Facebook, one of my bike friends said it took over 100 tries to get that shot - I have no idea where this information came from, but wow, that's dedication.

Mmmm office phones 
I have a buddy who works there, Cisco hooked them up with Chrome mini-metro messenger bags.

Today I am heading down to the LBS to install the following. Having a LBS that has a customer work stand and full use of their tools for no charge is an absolute win. Bought everything through them so everything is all good!
new bars
new bar tape
new tires
new chainring
new chain
new chainring bolts
new cog
new front brake pads

I met the co-founder of Cisco a couple years back. He had some side-project that involves nanotechnology and came on site to visit our Chief Scientist and myself, as it involved my area of expertise.
The guy was totally casual, dressed in sneakers, blue jeans and a cotton sweater. A couple minutes in he goes: "Do you know who I am?"
To which I responded: "Yeah, we googled you
."
Nice guy.

Great job security but voice engineers are never home to see their family, always working, evenings and weekends because the phone system can't be maintained during the day while business is using it.
Cisco is giving me a stack of expensive gear - Meraki security appliance, 24 port switch and stadium wireless controller. Of course I have to learn it, demo it and fix it for customers when it breaks. Almost rather have a messenger bag.

Bike is done. Feels really crisp right now. I suck at wrapping bars so I get to redo them tomorrow because the weather is supposed to be crap. Pics to come tonight.

Today I climbed Mt. Hamilton. Slow as ****, but I made it to the top where it was cold and the wind was nuts and I was woefully underdressed.

Today I discovered an extended (double) trailer for Planet Earth II.
Unlike the previous version, this one is going to have a score, and it was composed by one of my favorites, Hans Zimmer.
Makes me weep. Literally weep.
