1/4 — To mitigate the effects of #Starlink satellites on astronomy research, @SpaceX has developed a space-stable dielectric Bragg reflector film that reduces satellite visibility by an order of magnitude.

SpaceX will also be offering this film at cost to other operators! ❤️

@SpaceX

2/4 — @SpaceX has also developed a low reflectivity black paint, which is five times less reflective than the current darkest available space-stable paint, to coat various reflective #Starlink satellite components.

@SpaceX

3/4 — @SpaceX has also developed a special opaque coating for the backside of solar arrays and a special satellite maneuver called 'terminator tracking' to mitigate reflectivity.

@elonmusk

🧵1/7 — My take, by real estate analogy, of what happened between @elonmusk (buyer) and @Twitter (seller)

▫️ Seller lists the house as being less than 5% infested with termites

▫️ Buyer makes an offer and enters into a purchase agreement with the buyer

2/7

▫️ Purchase agreement includes a provision that seller will provide access to the house to the buyer's building inspector

▫️ Seller breaches the purchase agreement by not providing access to the basement and cellar of the house, rendering full inspection impossible

3/7

▫️ Nevertheless, building inspector estimates the extent of termite infestation is far more than 5%

▫️ On top of the modest foreseen costs for exterminators, it now appears whole sections of the house are structurally impaired and will need to be rehabilitated or rebuilt

🧵1/9 Energy Thread

Setting aside the impacts of fossil fuels on climate, environment, and health, there still remains 2 very good reasons for countries to transition to sustainable energy as fast as possible: Energy Security & Price

2/9

▫️ 80% of the world's proven crude oil reserves are controlled by only 8 countries.

▫️ At our current rate of production, the world's oil reserves will be depleted in 53 years.

3/9

▫️ 75% of the world's proven natural gas reserves are controlled by only 8 countries.

▫️ At our current rate of production, the world's gas reserves will be depleted in 47 years.

1/5 🧵— The 8 tell-tale signs of con artists:

▫️ Bait: They’ll offer you a small reward upfront, something exclusive that you desire or find appealing

▫️ Affinity: Claim their interests and motivations are aligned with your own, thus fabricating a connection and shared purpose

2/5

▫️ Familiarity: Claim to know you (which is not entirely untrue given they’ve researched you), thus fabricating a sense of closeness

▫️ Flattery: Compliment you in a manner that reinforces your own sense of identity, thus fabricating your sense of their identity

3/5

▫️ Empathy: Invoke a shared experience (positive or negative) that you can mutually empathize with, thus fabricating an emotional common ground

▫️ Vulnerability: Reveal a fault and/or claim to be a victim, thus fabricating sympathy and reinforcing the emotional connection

@elonmusk

🧵1/6— I believe there would be a relatively easy way to authenticate accounts as human @elonmusk

Create metric akin to a credit score for each account, let's call it a Human Score (HS), based on the premise humans engage far more w/ other humans than w/ spam or fake accounts

@verified

2/6— Build a social network graph where nodes are accounts and edges are directed, indicating who they follow

Start with @verified accounts & grow the graph from there. Incoming high-HS edges increase a node's HS. Incoming low-HS edges are ignored and have no effect on node's HS

3/6— All accounts have their Human Score (HS) publicly displayed. A badge (e.g. orange check) is awarded if the account has a high-enough HS to be deemed "human authenticated"

Newly created accounts get a probationary score w/ a newb badge for 1 year or some activity-threshold
