Everyone and their dog has a blog at this point. Why not me? You see, I don’t really like the idea of blogging, but I do enjoy taking notes. I take a crap tonnes of notes, and sometimes people want to see a copy of them.

In order to facilitate this, some friends and I created taproot, a collective note-taking effort which also automatically compiled pretty cool previews and an internet site. I still am one of the primary maintainers of taproot.

Tips

• A well-run startup should have 18 month of cash planned, and have a runway of 6 months to ensure you can always get acq-hired and “bail out”

Myths of Startups

• “Joining Big Tech” vs. “Starting a Startup” are not binary options
• In between these poles: joining an existing startup

Myth: “90% of startups of fail”

True statement: 90% of SMALL BUSINESSES fail. Venture backed tech startups are very different world: only 1% of small businesses are venture backed.

Lambda Calculus with state:

\begin{equation} e \to (x | \lambda x . e | e e | i | \text{new} | {!e} | e := e) \end{equation}

where:

• \(new\) allocate a new memory location \(x\) and return pointer (initialize \(x\) to \(0\))
• \(!e\) deref a pointer
• \(e := e\), which is assigning the pointee of the memory location at the first argument to the second argument

new

\begin{equation} \frac{l \not \in dom(S)}{E,S \vdash \text{new} \to l, S[l=0]} \end{equation}

The stationary-action principle states that, in a dynamic system, the equations of motion of that system is yielded as the “stationary points” of the system’s action. i.e. the points of “least” action. (i.e. a ball sliding down a ramp is nice, but you don’t expect it—in that system—to fly off the ramp, do a turn, and then fly down.

A statistic is a measure of something
