+Collection of spreadsheets for calculating suspension dynamics, brake bias, and so on.
+_I'm not an engineer, so use at your own risk._
+
+They're pieced together using information from several sources:
+
+- _Brake Handbook_, Fred Puhn, 1985.
+- _Engineer to Win_, Carroll Smith, 1984.
+- _Race Car Vehicle Dynamics_, Milliken & Milliken, 1994.
+- [_Springs & Dampers_](https://optimumg.com/springsdampers1/): Parts One through Six, Matt Giaraffa: OptimumG, 2018.
+- _Tune to Win_, Carroll Smith, 1978.

+
+Here is a list of some of the tools I use day-to-day.
+
+
+# Software
+
+- [Gentoo Linux](https://www.gentoo.org/) ---
+	One of the most solid barebones Linux distros I know of.
+	I use it on my desktop and laptop computers.
+- [OpenBSD](https://www.openbsd.org/) ---
+	Secure server operating system.
+	I use it to serve this website.
+
+	Unlike a GNU/Linux distro, OpenBSD is a single homogeneous system.
+	Everything makes sense and the documentation is really good.
+	Reminds me of [Plan 9](https://plan9.io/plan9/) in that respect.
+
+- [Acme](http://acme.cat-v.org/) ---
+	Originally developed for Plan 9, Acme is [Rob Pike's](https://commandcenter.blogspot.com/) user interface for programmers.
+	It's what we now call an IDE.
+	I'm writing this article in Acme right now.
+
+	Every piece of text in Acme can be a executed or piped into/out-of a script.
+	Very powerful.
+- [Dwm](https://dwm.suckless.org/) ---
+	Nice tiling window manager for X11.
+	Goes well with other Suckless accoutrements.
+- [Syncthing](https://syncthing.net/) ---
+	Syncthing is a sort of distributed filesystem.
+	I use it to synchronize files between my laptop, desktop, and phone.
+
+
+# Hardware
+
+- [Thinkpad T420s](https://www.thinkwiki.org/wiki/Category:T420s) ---
+	I've had this laptop for a few years now; no complaints.
+
+	I replaced the hard drive with an SSD and threw some extra DDR3 in there.
+	The 10+ year old 4-thread Sandy Bridge i5 is actually fine.
+	I'm waiting for someone to make a [serious multithreaded](https://netlib.org/utk/papers/advanced-computers/tera.html) RISC-V CPU, but unfortunately everyone seems to be obsessed with high clock speeds and out-of-order-execution chips that use as much die space and power as possible.
+	That [Esperanto ET-SoC-1](https://youtu.be/LmUu-lN7D0k) looked promising, but apparently they went out of business or something?
+
+	Anyway, the T420s has a sturdy magnesium frame, a good keyboard, and a three-button touchpad which is essential for Acme and CAD programs---I don't know how people live without one.
+
+- [USBtin](https://www.fischl.de/usbtin/) ---
+	Simple USB-to-CAN interface by Thomas Fischl.
+	Works with [SocketCAN](https://docs.kernel.org/networking/can.html).
+	Used to test and debug systems that incorporate a CAN bus, like [this](http://git.samanthony.xyz/can-gauge-interface.git/).
+
+- [Espotek Labrador](https://espotek.com/labrador/) ---
+	Combined oscilloscope, signal generator, power supply, logic analyzer, and multimeter.
+	Obviously a tiny $30 board is not as good as real lab equipment, but it's small and cheap and good enough for now.
