9/ The staffs and management at Naomi House for women, the homeless shelter @PoverelloHouse were incredibly abusive. They constantly threatened vulnerable, mostly mentally ill women, with the sts for "disobeying" some new made-up rule(s). What jerks! -Michaela cc: @SoniaMDLR

OMG ya'll, I have major decode! Stick with me this is going to be good!

"The engineers on my team just want to code. They don't want to have anything to do with product. They just want specs. What do I do?"

1/n Are you asking them do to X *and* do their "day job" as defined by their managers (and frankly your roadmap) ?

If so, start there...

2/n Do they have a reason to believe that doing X will in any way improve the quality of the product and make their lives easier? Have they ever seen X "work" ?

Show don't tell.

3/n Is there average day/week a quagmire of unnecessary meetings, wading through tech debt, struggling to get *anything* to work ... and jumping through process hoops to prove their worth?

If so...no they will not have bandwidth.

4/n How do incentives work on the engineering team? Maybe they want to help, but their "grade" is determined by something altogether different.

"I'd love to, but I am on the hook to deliver [some project] this quarter to make a good impression..."

Talk to eng management.

5/n Have they had any time to practice?

Or did they get thrown into the deep end the first time they were given a shot ... expected to brainstorm on demand, be as vocal as practiced PdMs and designers, and "participate" !

Make it safe to practice. Reasonable expectations.

THREAD ON IRONFLY

These days the most preferred strategy for option sellers due to improved margins is IRONFLY. It's essentially a short straddle with long strangle. Long strangle acting as 'WINGS', which help in capping the unlimited risk associated with a short straddle.(1/n)

You can also view the position as a combination of Cal & Put credit spreads, if that makes it more easy for you.

There are 3 important things to understand while trading this strategy:

1) Initial size of the Wings
2) Risk Management
3) Adjustments

(2/n)

Since we are selling an ATM straddle, the 1st question is how far our wings should be? Ideally i sell .50 delta straddle & buy .20 or .10 OTM strangle, depending on my view on volatility. So the distance of wings depends on the IV setup. Higher the IVs, greater the distance.(3/n)

If you don't understand greeks, then ideally with 30 days to expiry (dte), wings should be around 300pts either side. If your trading in weekly then it should be not more than 200pts. Higher the premiums, higher the distance as we have more cushion of theta. (4/n)

It is important to understand that we need to reduce the distance of wings with time so as to manage our RISK in gap openings or sudden volatile move. So for eg. if you started with 300pt wings with 30dte, the wings wouldn't give the same protection when there is 7dte. (5/n)

Environmental impact of carrier bags

• In this life cycle assessment of supermarket carrier bags we can conclude that the environmental impact of all types of carrier bag is dominated by resource use and production stages. It is because there is so much energy that is needed in the production stage.

Transport, secondary packaging, and end-of-life management generally have a minimal influence on their performance.

Whatever kind of bag is actually utilized, the essential towards decreasing the effects are actually towards recycle it as often times as feasible as well as where recycle for buying isn't practicable

The recycling of traditional HDPE as well as various other light-weight provider bags for buying as well as/or even as bin-liners is actually critical towards their ecological efficiency as well as recycle as container linings create higher advantages compared to reusing bags.

It's a slow, snowy afternoon. How about a 🧵 on "rationalists" & "rationalism"? I want to talk about what real rationalism might look like & what people devoted to rationalism might actually behave like--and how that differs from what you often see from self-styled rationalists.

Caveat up front: this is not about Slate Star Codex, which I haven't read regularly enough to have an opinion on, or about the recent controversy between SSC & the NYT. I'm more interested in the *idea* of rationalism (vs. the practice).

The core premise of rationalism, as I understand it, is simply that humans' cognitive machinery was not designed by evolution to find truth, but rather to advance the interests & welfare of the collective -- a Venn overlap, but not the same thing. Therefore ...

... reasoning well, both individually & as groups, requires special effort. It requires consciously trying to set aside the parochialism, biases, & other distortions that typically characterize our thinking -- resisting, to some extent, the dynamics of group membership/welfare.

That's all fine. I agree entirely that we should make special effort to reason well & to guard against the typical failures of reasoning to which we humans are prone. I believe it's the best (maybe only) way forward as a species. So far so good.
