So it turns out that Google Chrome was making everything on my computer slow *even when it wasn’t running*, because it installs something called Keystone which is basically malware.

I made a website because this shouldn’t

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.

it's done.

I got a Toshiba T1200, which has a bad screen, and a dead CMOS battery, and I thought the hard drive was broken too...

but I rebooted it and heard a KTHUNK and a really loud spin-up noise and holy shit, the hard drive works!

and it still has files on it. the newest date is January 1994.

It's a 21mb hard drive, with ~37k of bad sectors.

This fucker is never going to spin up again, so I better go find some serial cables and copy shit off now.

The backlight is fucked so I'm shining a flashlight on it.
without it, it looks like this.

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!]

The Phantom of Heilbronn (or how for 16 years the German police hunted a serial killer who didn't exist)

(Thread, non sweary version here: https://t.co/iDOIhaFgIT)

Between the years of 1993 and 2009, police in Heilbronn, Germany were tracking just about the most elusive serial killer since Ted Cruz.

Known as the Phantom of Heilbronn, or occasionally The Woman Without A Face, she was implicated in so many crimes that the police eventually put out a reward of €300,000 for any information leading to her arrest.

The case that brought her to the media's attention and earned her two ridiculously badass nicknames

(honestly, if you don't want people to do murders you're going to have to come up with less glamorous nicknames - what's wrong with Jack Shitshispants or the Zodiac Cuck)
