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.
@nicolefv 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"
@nicolefv 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, w/aplomb"

https://t.co/OjY5KSDbNK
@nicolefv 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)
@nicolefv "Research and development is not a business that can be carefully planned and directed, not if you expect to make progress rapidly and economically." Burton Klein, Economist, 1958.

"What is the underlying science [and theory]?
@nicolefv "What accounts for successful innovation? What role do leadership and organizational design play?" What incredible questions!

"Today Rabinow, professional inventor w/230+ US patents, an advisor to NIST: 'all inventors come up w/many idea; you must know that most are trash."
@nicolefv One aspect Westrum hints at is need for constraints & scarcity. One factor for Sidewinder success is that it was hidden as an official program for years, classified as "fuse research," which could be easily classified.

This prevented expansions in budget, oversight, meddling
@nicolefv Counter-examples at this time were the Falcon (which became Phoenix), and Sparrow, both of which underperformed for years, unable to hit their targets.

Dr. Bill McLean is the center of the narrative, Ph.D. from Caltech, who led the program, and eventually China Lake
@nicolefv One dynamic with China Lake (let's call it CL) was minimum of organization and hierarchy: the important point: "Each person did the job for which they were best fitted. One day they'd be directing associates. Next day, it could be other day around."
@nicolefv In the interview, Dr. Westrum suggested that this is the opposite of a hierarchy, where managers tell workers what to do — instead, you want an org that give the job who can best do it.

That could be answering a question, dictating what the work should be, or doing the work.
@nicolefv Aside: that sounds kind of obvious, right? But contrast this to how many orgs actually work. This is about whether or not the organization respects knowledge.

"Lockheed Skunk Works shared many similar traits... Director "Kelly" Johnson promised P-80 Shooting star in
@nicolefv "...in 180 days; his hand-picked team did it in 141 days." Skunk Works was a small team, but China Lake had figured out how to scale this dynamic to thousands of employees
@nicolefv "Merle Tuve, maestro in charge of developing the proximity fuse in WWII, once said: "I don't want any damn fool in this laboratory to save money. I only want them to save time."

(Also resonates w/me. As @chawlady wrote: we stopped optimizing for cost, and optimized for speed)
@nicolefv @chawlady "Management theorist Deborah Dougherty argued successful products generally come from orgs whose design, mfg, sales, & marketing depts focus on meeting customer’s carefully studied needs.
@nicolefv @chawlady "Getting these four departments to focus on a common, well-chosen goal is the secret to success. What is remarkable about McLean is that he combined in a single person all these activities."

Dr. Westrum says that the literature calls this the "technical maestro"
@nicolefv @chawlady "In conceiving his missile, McLean determined to use “the minimum amount of garbage you had to hang on the rocket in order to make it home.” Experiments would tell him just how much garbage this was.."

(other missile programs burdened with lots of premature requirements)
@nicolefv @chawlady The dynamics of large, public, official missile programs (not Sidewinder): "years of effort go into preparing the systems, and often tests went badly. Millions of $$, and in some cases, fate of whole business divisions rode on the outcomes... Raytheon had 6K engrs on Falcon
@nicolefv @chawlady "...emotions ran high in the control room, and a man could break into tears when his missile failed." (painting the high-stakes dynamics in these massive programs that prematurely created rigid boundaries)
@nicolefv @chawlady Okay, taking a break. Will continue soon. I feel like I highlighted the entire book — I'm writing up my notes to clarify my own thinking on this. (thank you @RoamResearch)
...also, in addition to @nicolefv, while I'm thinking about it, my thanks to @jezhumble who first introduced me to Dr. Westrum's work, as it appeared in Lean Enterprise, and @allspaw, who sent me two of his papers over the years!

More to come later...

Fake chats claiming to be from the Irish African community are being disseminated by the far right in order to suggest that violence is imminent from #BLM supporters. This is straight out of the QAnon and Proud Boys playbook. Spread the word. Protest safely. #georgenkencho


There is co-ordination across the far right in Ireland now to stir both left and right in the hopes of creating a race war. Think critically! Fascists see the tragic killing of #georgenkencho, the grief of his community and pending investigation as a flashpoint for action.


Across Telegram, Twitter and Facebook disinformation is being peddled on the back of these tragic events. From false photographs to the tactics ofwhite supremacy, the far right is clumsily trying to drive hate against minority groups and figureheads.


Declan Ganley’s Burkean group and the incel wing of National Party (Gearóid Murphy, Mick O’Keeffe & Co.) as well as all the usuals are concerted in their efforts to demonstrate their white supremacist cred. The quiet parts are today being said out loud.


The best thing you can do is challenge disinformation and report posts where engagement isn’t appropriate. Many of these are blatantly racist posts designed to drive recruitment to NP and other Nationalist groups. By all means protest but stay safe.

If u are looking to enter a scrip just before the breakout
what would u look for?
How would u identify scrips just before breakout?

Here are a few pointers
Carefully understand the them and use at ur own discretion
(All comments r compiled from a question i posed)

1/23

Price is testing the same resistance repeatedly since long.
But now in recent times it's forming multiple candles near the same resistance with low volume.
Observe it and see for opposite move.
As soon as u get a positive candle, get in to it.

2/23

1. Volume buildup (vol > when resistance point created) along with, increase in OI, increase in delivery % on HTF
2. On LTF, price stalling around breakout area for at least 1-2hr.
3. No major events.

3/23

Stock reaching breakout LVL with HL-HH
Contraction of price and volume near it especially near 20 days ma.
If there is any breach of the latest HL it should be followed by a bullish candle with good volume.
Left side of the chart has a rally with a very steep slope of ma.

4/23

Number of wide range green bars with high volumes.
If stock is at its ATH then it adds more conviction bcz there wont b supply after that point

Consolidation below the resistance, volume of the candles & strong bullish candle closing at near highs just below the resistance

5/23

THE TRADER'S EDGE: THINKING IN PROBABILITIES

Casinos make consistent profits day after day and year after year, doing something random

At the same time, most traders believe that the outcome of the market's behavior is not random,yet can't produce consistent profits

Thread 🧵


What casino owners ,professional traders know is that probable outcomes can also produce consistent results if you " Have an edge" and trade on a large enough sample size.

The best traders treat trading like a numbers game.

1. To illustrate, let's look at the game of blackjack-


In blackjack, the casinos have approximately a 4.5-percent edge over the player.

This means that casinos will make profit over a large enough sample size, even after several winning streaks and big profits of many players.

At the end of the day, week, month, or year, the casino always ends up with approximately 4.5 percent of the total amount wagered.

That 4.5 percent might not sound like a lot, but let's put it in perspective.

Suppose a total of $100 million dollars is wagered collectively at all of a casino's blackjack tables over the course of a year. The casino will net $4.5 million.

What casino owners and pro traders understand about the nature of probabilities is that each individual hand played

A Thread on~ O V E R T R A D I N G

Sitting and observing the numbers flicker on the screen might be very exciting.


But have you ever felt like you might've done better? Or you're just too tired of waiting that you punch an order right in?

That's a Bad Idea.

So, Let's understand the reasons behind it and try to find a way out.

1. Not having a trading plan makes you clueless.
Your impulses start to take control of you.

2. Having a trading plan; But still taking impulsive/ random trades.
Because of adrenaline rush or gambling instinct.

3. Revenge trading
When you try to force a trade in order to recover from a previous loss.

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:

*Heads-up that this thread will feature some extreme examples of homophobia and transphobia.*

Hey folks, have you ever wondered why trans people face constant accusations of fetishism, sexual predation and child abuse/grooming? Well, today let's talk about stochastic terrorism.

So, first we have to talk about what stochastic terrorism actually is. Remember when there was a conspiracy that there was a pedophile ring operating out of a pizza parlour basement, and a crazed gunman showed up? It's that sort of incitement that stochastic terrorism describes.

It's the demonisation or incitement against a group of people or individuals with the intent that other, unaffiliated parties will act upon it; it's the releasing doctored footage and a shooter show up at Planned Parenthood as a direct result of what he's been led to believe.

So with that in mind, let's talk about Russia's extreme anti-LGBT laws that banned the "promotion" of LGBT lifestyles to children. A move that specifically marked LGBT people as a threat to children, and resulted in neo-nazis meting out vigilante "justice" against gay men.


Groups such as this would lure unsuspecting gay men via dating sites, and brutalise and humiliate them on camera. They did so under the guise of combating child abusers, one group calling themselves "Occupy

Lessor known facts of Sudarshan Chakra or Neela Chakra of Puri Jagannath Temple.

The metal wheel at the top of Bhagwan Jagannath temple is also known as Neela Chakra (Blue Wheel). The wheel is made of eight metals comprising of.. 1/n


iron, copper, zinc, mercury, lead, brass, silver & gold. It's circumferance is about 36 feet & it is so designed that there is a wheel within the wheel. The circumferance of the inner wheel is about 26 feet. Eight hubs join together the inner and the outer wheels. 2/n


There are decorative designs on the outer wheel. The thickness of the Neela Chakra is 2 inches.The wheel is said to be Bhagwan Vishnu's most powerful weapon, Sudarshana Chakra. Inside Jagannath temple, Lord Vishnu's wheel is also worshipped in the name of 'Sudarshana'. 3/n


But inside the temple Sudarshana is not in the shape of a wheel, but in the shape of a small wood pillar placed to the left of image of bhagwan Jagannath. It is believed that the same Sudarshana is also at the top of the temple and is known by the name of Neela Chakra. 4/n


There is a specific category of people among the temple sevaks to serve the Neela Chakra and they are known as Garuda Sevaka or Chunara Nejoga. The pilgrims hold these sevaks in high esteem because everyday at Sunset. 5/n

So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.


The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.

This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.

The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."

This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.
