1/ Just realized this morning that it was 5 years ago today that I invested in @densityio ... it has truly been such a great career experience for me. Some notes ...

Many of you have seen the famous Westrum Organizational Typology model, so prominently featured in State of DevOps Research, Accelerate, DevOps Handbook, etc.
This model was created Dr. Ron Westrum, a widely-cited sociologist who studied the impact of culture on safety
Thanks to Dr. @nicolefv, I was able to interview him for an upcoming episode of the Idealcast! 🤯
It was a very heady experience, and while preparing to interview him, I was startled to discover how much work he's done in healthcare, aviation, spaceflight, but also innovation.
I've read 4+ of his papers, so I thought I was familiar with his work. (Here's one paper: https://t.co/7X00O67VgS)
I was startled to learn he has also studied in depth what enables innovation. He wrote a wonderful book "Sidewinder: Creative Missile Development at China Lake"
Dr. Westrum writes about China Lake Research Labs: "its design and structure had one purpose: to foster technical creativity. It did; China Lake operated far outside the normal envelope... Sidewinder & others were "impossible" accomplishments,
I love this book because it describes traits of organizations that routinely create and maintain greatness: US space program (Mercury, Gemini, Apollo), US Naval Reactors, Toyota, Team of Teams, Tesla, the tech giants (Amazon, Google, Netflix, Google)

1/ Feels like a good time to tell the story of how I went from broke to a millionaire to broke again in 2017/18 again...
Yesterday was brutal for some people...
Losing life-changing money sucks, losing any money sucks...you can chase the market or you can change your strategy.
2/ The original thread is gone but you can read it here.

tl;dr
- Traded $32k to $1.2m
- Thought I was a genius
- Made poor investments
- Didn't conserve capital
- Peaked at 150 BTC
- Lost nearly all of it
2 weeks from losing my house + no income. Oops.
3/ I am going to assume you are in it for the money rather than the tech. Yeah, you might Tweet about the amazing blockchaining of cross-border payments and oracles yadda yadda...really, you are in it to make money.
If you are really in it for the tech, go and build something.
4/ Okay, so if you want to make money, trading is super hard, you are trading against:
- Better traders than you
- People who can move markets
- Unknown information
And if you are trading with leverage you might blow up your account with the volatility.
5/ If you are not trading, you are investing. Okay, so what are you investing in?
I made the decision that the crypto with the best opportunity of existing in 10 years is #Bitcoin:
- Solves a genuine problem
- The right tech
- A proven track record

A 🧵on the basics of block and bulk deals.
Block and bulk deals are large purchases of stocks by investment banks, mutual funds, hedge funds, pension funds, FIIs, and promoters. Tracking block and bulk deals can help give you a sense of what these large players are thinking.
A single transaction where shares more than Rs 10 crores or the number of shares traded are more than 5 lakh is considered a block deal.
Block deals are carried out in separate trading windows. This trading window operates in two shifts of 15 minutes each:
Morning trading window from 8:45 AM to 9:00 AM.
Afternoon trading window from 2:05 PM to 2:20 PM
Block deals happen in different windows to reduce volatility and sudden price movements. Given that they are traded in a separate window, they do not show up on the volume charts.
Brokers facilitating the transaction are required to inform the exchange. You can track bulk and block deals on NSE & BSE:

Working on a problem reduces the fear of it.

It\u2019s hard to fear a problem when you are making progress on it\u2014even if progress is imperfect and slow.
Action relieves anxiety.

We often avoid taking action because we think "I need to learn more," but the best way to learn is often by taking action.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.
Legacy site *downloads* ~630 KB CSS per theme and writing direction.
6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices
https://t.co/qyl4Bt1i5x
PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.
735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices
https://t.co/w7oNG5KUkJ
The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.
The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
