Please please please take your cyber security seriously even if you don’t consider yourself a high risk person. Here are a few easy things to start with. 1/n

Switch from WhatsApp to Signal and enable disappearing messages. Most of us cannot stop using WhatsApp entirely but at least turn off back ups to Google Drive or iCloud. 2/n

Do not have private conversations using the messaging service on any social media platform like Facebook, Instagram or Twitter. 3/n

Switch from Gmail to ProtonMail or any other secure email service provider. 4/n

Switch from Google Docs to CryptPad or RiseUp Pad.

There are only 3 real challenges to free speech at the tech level a) the need for CDNs at scale b) distortions of net neutrality c) nation-state firewalls.

All other claims are about social governance on private sites, where applying free speech doctrine is a stretch at best

Baseline free speech has expanded modestly since 1776 or whatever your reference point is.

About 20% beyond core case of government-critical speech in formally public spaces and media I'd say.

You can (for example) have more kinds of conversations in a bar without getting punched or kicked out by other patrons or management. You can teach more things in colleges than 100 years ago.

That's a genuine de facto increase in practical, informal free speech/expression.

But online free "speech" is, as @reneed has pointed out, not an expansion of free speech at all, but an expansion of reach. It is like the secondary freedom of the press to print as many copies as they can afford, not primary freedom to say what they want

If a newspaper wants to print more copies it has buy more printing equipment and front more upfront costs. Reach for a paper publication is not "free", but a function of desired circulation, which in turn is a function of demand prediction etc. But that logic is obscured online.

Torn between "I think losing $100 million when someone beats you at security research is pretty much exactly what you signed up for doing yield farming" and "Maaaaaaaybe not the future of finance you were expecting, huh."

How to put this in regular finance terms...

Suppose hypothetically you have an account at a brokerage with some valuable asset in it. You take a margin loan against that asset to fund your normal spending, or pay a tax bill, or maybe buy something at another brokerage.

For reasons known only to the brokerage, they don't denominate your loan in dollars. They denominate it in shares of a money market fund, which are worth $1 +/- epsilon and basically never deviate from that.

And you think "Hmm, I have a large equity cushion against this loan."

One day, a computer system at the brokerage reports, sorta-kinda erroneously, that the value of the money market fund is actually $1.30 per share. The equity cushion is gone. Your valuable asset is sold, at timing you didn't choose, at wrong price, to pay an inflated phantom debt

And your recourse is... probably tweeting at patio11 saying he finds too much joy in this.

Which I don't; I just feel like this is why you don't trust a CPU built out of redstone to build reliable financial infrastructure on top of.

Darkroom

Been reading up a lot about these jabs, esp as I know they are going to be a condition of a return to normality

Was on a zoom call last evening with a testing company that had some fascinating evidence on protection etc.

I have more reading to do.

I do not want to be coerced into something I don't want, BUT i want normal back as soon as possible.

Basically i'm at the point in my isolation and thinking that I'll take whatever just so this bullshit can end.

That is a desperate mindset, but so is 12 months of being cut off from the world.

All i have is what goes round and round in my head.

There's no one else to help balance it.

So i'm in group 6, and my surgery are doing group 6 right now. And i am at the point i want to do it to get it DONE.

And also to study what happens. Because i have that kind of mind.

I remember Pandemrix.

But we live with risk every day.

I risk my life climbing walls with only a harness around my waist to catch me as i lean back and fall off

And rational risk assessment is at the heart of everything going wrong these last 12 months

THREAD: Meditations on marriage metaphors in Ruth

The book of Ruth is, of course, a story about a beautiful marriage. But even before the courtship and the wedding and the important genealogy at the end, we find interesting language that is strikingly reminiscent of Genesis 2:24

That important verse reads:

'Therefore a man shall leave [יַֽעֲזָב] his father and his mother and hold fast [וְדָבַ֣ק] to his wife, and they shall become one flesh.'

The verb עזב can be quite strong in force. For example, Joseph leaves behind [וַיַּעֲזֹ֤ב] his garment as he flees from Pharaoh's wife's sexual advances. Countless times, Israel is depicted abandoning the LORD, for example in Judg 2:12 [וַיַּעַזְב֞וּ], and going after other gods.

Likewise, the verb דבק is rather striking. Lot is mortified of disaster overtaking him [תִּדְבָּקַ֥נִי] as he flees from Sodom. Israel is commanded in Deut 10:20 to cling fast [תִדְבָּ֔ק] to the LORD and serve him and swear by his name.

Together they illustrate how radical God designed marriage to be. Marriage is a real severing of family relations in order to form a new, permanent bond with another human being.

Something very similar to this takes places in Ruth's life.

So, I want to talk about how sexual harassment and fair pay are linked at Google (and beyond), because I think that's an angle that isn't being highlighted enough in the coverage of these walk-outs. I'm going to frame it largely around my personal experience there. Thread.

When I was sexually harassed by the director of the area I was working in, I was afraid to report it because I was worried that "getting him in trouble" would result in the subtle retaliation of missed leadership opportunities.

I wanted to continue working on the team I was on, because I'd gained a lot of very deep knowledge and expertise in that area, as well as reputation and camaraderie with the other folks working in that area. I didn't want to make the situation more "difficult."

To get promoted at Google, several need to happen: 1. you need opportunities for ownership and leadership above your current level (basically, opportunities to show you're working at the next level you're trying to get promoted to). The work you're "assigned" has a big impact.

2. You need glowing reviews from peers, *at or particularly above the level you're hoping to get promoted to.* Basically, you need people a lot more senior than you to say you're doing awesome work.
