These past few days I've been experimenting with something new that I want to use by myself.

Interestingly, this thread below has been written by that.

Let me show you how it looks like. 👇🏻

Recently I just refunded all Poster's sales from Gumroad. Being that said, I decided to not using that service anymore.

Here's a little story \U0001f447\U0001f3fb

When you see localhost up there, you should know that it's truly an experiment! 😀

It's a dead-simple thread writer that will post a series of tweets a.k.a tweetstorm. ⚡️

I've been personally wanting it myself since few months ago, but neglected it intentionally to make sure it's something that I genuinely need.

So why is that important for me? 🙂

I've been a believer of a story. I tell stories all the time, whether it's in the real world or online like this. Our society has moved by that.

If you're interested by stories that move us, read Sapiens!

One of the stories that I've told was from the launch of Poster.

It's been launched multiple times this year, and Twitter has been my go-to place to tell the world about that.

Here comes my frustration.. 😤

An irony of facebook's situation.

Sheryl got her MBA at Harvard. One of the most famous cases (Extra Strength Tylenol) in one of the most famous classes (Business History) she took: in 1982, someone put cyanide in Extra Strength Tylenol capsules and killed 7 people in Chicago.

What do you do when someone turns your product into a weapon? When they use the system you built to harm? James Burke, CEO of J&J, was shockingly open with the public, he pulled the product and made significant packaging changes to make product safer (but not tamper-proof).

He over-shared every step along the way re investigation, redesign, stood up as both CEO and human. The reintroduction of new Extra Strength Tylenol succeeded. Burke saved the brand.

But four years later it happened again. A killer put cyanide in the capsules, this time a woman in Yonkers died. Same CEO, Burke, pulled the product again, completely changed the form factor from capsule to caplet and relaunched *again*. It worked *again*. How'd they do that?

Burke (CEO) tapped J&Js goodwill bank account w/ the public. Two big withdrawals from that bank account in four years + 8 dead bodies! But his honesty, openness, humanity (choked up about the deaths more than once), humility kept the goodwill bank balance positive the whole time.

Users: hey can you get rid of the Nazis please

Twitter: ok sure, we've changed the stars to hearts for likes

Users: no no, zero Nazis please

Twitter: yep we're getting rid of Vine

Users: nah hey, what about the Nazis

Twitter: ok ok fine, no more likes

Really though, if you had to ask any average user what were the main things leading to a bad "quality of debate" on this bad website, the tiny little heart symbols would not exactly be at the top of most people's lists

We're kicking off the Privacy Tech session at #enigma2021 with Mitch Negus speaking about "NO DATA, NO PROBLEM—GIVING NUCLEAR INSPECTORS BETTER TOOLS WITHOUT REVEALING STATE

A nuclear catastrophe hasn't occurred... yet. So we need to stay vigilant. Nuclear inspectors go in according to treaties to check what's going on and check compliance with treaty rules.

But as sophisticated analytics become more common, states will only want to share the minimum amount of information necessary under the treaty.

But perhaps we can use MPC -- secure multi-party computation

Yao's garbled circuits were first demonstrated on the millionaire's problem -- figuring out who's richer without revealing actual amounts.

Used for other things like cryptocurrency these days.

Can we use this for nuclear inspection?

MPC can be used to compute anything computed by a computer [but it's expensive!]

Elastic didn't really relicense ElasticSearch. It forked it.

🧵 A thread.

1/18

There's a lot of talk in the open source community about the cost of forking.

2/18

- "Forking is best avoided."

- "Forking is a last resort option."

- "Forking is like a nuclear weapons. It's a defensive threat."

3/18

Forking is seen as impractical and extremely expensive.

And that's a Really Good Thing(tm).

It's a forcing function for figuring out solutions that are broadly acceptable across the community.

4/18

The thing is, the cost of forking is mostly a function of three things:

1⃣ the size of the community that you can bring along with you,
2⃣ whether you need to rename your fork (who owns the trademark), and
3⃣ how much infrastructure you need to rebuild.

How to sell Strangles in weekly expiry as explained by boss himself. @Mitesh_Engr

• When to sell
• How to do Adjustments
• Exit

1. Let's start option selling learning.
Strangle selling. ( I am doing mostly in weekly Bank Nifty)
When to sell? When VIX is below 15
Assume spot is at 27500
Sell 27100 PE & 27900 CE
say premium for both 50-50
If bank nifty will move in narrow range u will get profit from both.

Beautiful explanation on positional option selling by @Mitesh_Engr
Sir on how to sell low premium strangles yourself without paying anyone. This is a free mini course in

Few are selling 20-25 Rs positional option selling course.
Nothing big deal in that.
For selling weekly option just identify last week low and high.
Now from that low and high keep 1-1.5% distance from strike.
And sell option on both side.

1st Live example of managing a strangle by Mitesh Sir. @Mitesh_Engr

• Sold only

Sold 29200 put and 30500 call
Used 20% capital@44 each

2nd example by @Mitesh_Engr Sir on converting a directional trade into strangles. Option Sellers can use this for consistent profit.

• Identified a reversal and sold puts

• Puts decayed a lot

• When achieved 2% profit through puts then sold

Already giving more than 2% return in a week. Now I will prefer to sell 32500 call at 74 to make it strangle in equal ratio.

To all. This is free learning for you. How to play option to make consistent return.
