I don't often promote myself on here, but I should. I have done some things that I am proud of. So here is a thread of episodes from @OurTurnPodcast that I contributed a segment and/or co-hosted. #RPG #podcast

👇Thread.

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!

This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?

One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.

The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.

@ChenHuailun here. I'm adding a supplementary thread before today's scheduled one to expand on the origins and early history of the Church of the East (aka the Nestorian Church) ~ahc #jingjiao 1/

The Church of the East traces its origins to the christological position of the School of Antioch, which held that the human and divine and human essences (ουσία) of Christ were united in a single prosopon (πρόσωπον). ~ahc #jingjiao 2/

This ran against the position of the School of Alexandria, which held that the two essences of Christ were united in a single hypostasis (ὑπόστασις). In general terms, hypostasis is more inherent than prosopon. ~ahc #jingjiao 3/

One implication of the Antiochene rejection of the hypostatic union is that Mary could not accurately be called the Theotokos, or God-bearer. Instead, she is the Christotokos, the Christ-bearer. ~ahc #jingjiao 4/

These Christological debates were further complicated by Syriac terms such as 'kyana' (ܟܝܢܐ), associated with 'ousia' but later translated to 'hypostasis' by Syrian Orthodox; and 'qnoma ' (ܩܢܘܡܐ), sometimes contentiously translated as 'hypostasis' or 'person.' ~ahc #jingjiao 5/

THREAD: 15 of the most useful razors and rules I've found.

Rules of thumb that simplify decisions.

Bezos' Razors:

• If unsure what action to take, let your 80-year-old self make it.

• If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison.

Skinner's Law:

• If procrastinating on an item, you only have 2 options:

1. Make the pain of not doing it greater than the pain of doing it.

2. Make the pleasure of doing it greater than the pleasure of not doing it.

Luck Razor:

• If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line.

I used this razor to go for drinks with a stranger rather than watch Netflix.

In hindsight, it was the highest ROI decision I've ever made.

Bragging Razor:

• If someone brags about their success or happiness, assume it’s half what they claim.

• If someone downplays their success or happiness, assume it’s double what they claim.

The map is not the terrain.

🎉🎉 PHP 7.3 is here!

Here are the things I'm excited about.

🚂 Trailing commas in function/method calls!

This will certainly be a required styling choice for me. Same delightful benefits of trailing comma in multi-line PHP arrays, and JavaScript objects.

🧵 Less disgusting heredoc syntax!

Inlining heredoc strings in any way right now is grrrosssss. Now we get sensible capabilities. Everything that was wrong with it is now fixed!

(Ignore the bad syntax highlighting)

☠️ Finally, not-so-silent json_decode error detection!

This really sucked before, now it just sucks a bit less (who wants to pass a 4th param and pass 2 default params first? (helper function anybody?)

📜 Not horrible functions for getting the first and last item (or key) from an array!

Before you either strung a bunch of functions together or messed with internal array pointers. This is a much-needed improvement.

I want to explain what happened to tumblr overnight. And why Twitter as reached it's dream (or have come ever so close to it)

Yahoo, who bought Tumblr years ago, used to have a huge adult presence on the early net. They allowed adult groups and what not.

However, people and bots (just like now) misused the service, and Yahoo were forced to make a choice. They made private the groups (and later closed them down and sold some of it to other companies) and then ended their chatrooms on yahoo messenger...

after a incident with one of the chatrooms vid cams. The damage was done, Yahoo Messenger lost a lot of people - and with the closing of the groups - backpage and Craigslist came more important.

Now backpage is no more and Craigslist is slowly passing away. Tumblr had a semi strong community, but once 2014 came around and both porn, and political bots exploded the quality started to go down,
