Today, I had lunch with a friend who owns a small construction company (like 5 employees).

He told me he's spent much of the last five years writing code, building this complex line-of-business app in Visual Basic and MS Access. And that it's essentially saved his business.

It's interesting, because here's this construction worker, used to working on physical things, talking about how Stackoverflow made such a difference in his life.
He has discovered on his own some of the same things we talk about here. He started rewriting his VB into C#, got one form done, and realized what a huge job it would be. And then decided it wasn't worth it to refactor everything just to have the latest language.
He talked about worrying he would build something that would become too much of a house of cards and that it would become unmaintainable.
We talked about automated testing, which he'd "heard of before". He was very curious why you'd want to do that, and what benefit it would bring.
He said he only had one other friend who knew anything about code + construction. He knows of dozens of small construction companies who are still doing everything manually, and badly.

Meanwhile, his company has consistent automated estimates, purchase orders, and invoices.
He has no idea what Silicon Valley is all about. He'd never heard of Slack. He just needed code to help his company survive, and discovered he loved it.

I asked him if he wanted to code full time someday, and he said, "Definitely."
His son is now studying computer science at a university and my buddy is excited to possibly work with him at some point in the future.

Code is changing everything. Or, rather, _accessible_ code is changing everything.
One postscript: as we were about to leave, he said, "I might be weird, but I REALLY LOVE debugging. It's so satisfying!"

"You're going to do just fine, buddy." 😂
PPS: I spent years working in construction prior to coding. More here: https://t.co/qGiueCPVUI
I should probably tweet more about my experiences back then. It was in the dark ages, you know, 1996-2005.
Here is another thread about some of the home design I used to do: https://t.co/Nl52s0SONt

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

https://t.co/FBfXhUrH5d


Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.
